Cefadroxil has been used for the treatment of acute osteomyelitis. However, its pharmacokinetics and pharmacodynamics have not been studied in these patients. We evaluated the kinetics and dynamics of cefadroxil in a pediatric patient with osteomyelitis caused by Staphylococcus aureus. After initial clinical improvement on intravenous nafcillin, the patient received oral cefadroxil, 60 mg/kg every 12 h. Blood samples were collected at 0, 1, 2, 4, 6, 8 and 12 h; bactericidal titers were determined at 2 and 12 h. Cefadroxil was measured by an HPLC method. The peak and trough serum concentration of cefadroxil was 35.4 and 0.5 micrograms/ml, respectively. The oral clearance and elimination half-life were 11.5 ml/min/kg and 2.4 h, respectively. The peak bactericidal titer was 1:4 and the trough titer was less than 1:2 for the infecting organism. The child's finger appeared worse with an increase in swelling and erythema after 2 days of cefadroxil therapy. Cefadroxil was discontinued and the patient was treated successfully with intravenous nafcillin. The apparent failure of cefadroxil therapy can be explained by lower than recommended peak (greater than or equal to 1:8) and trough (greater than or equal to 1:2) titers for therapeutic success. Thus, an alternative dosage regimen of cefadroxil should be considered in the future studies.

Ten cephalosporin derivatives (cefaclor, cefadroxil, cefalexin, cefazolin, cefoxitin, cefuroxime, cefoperazone, cefotaxime, ceftazidime, ceftriaxone) were analyzed by capillary zone electrophoresis using different background electrolyte solutions at different pH values. Electrophoretic mobilities of the analytes were calculated, the influence of the electrophoretic parameteres on the separation was established and the analytical conditions were optimized.

In 17 patients (7 with normal renal function, 10 with impaired renal function) who underwent renal surgery, renal tissue samples and blood samples were taken 3-4 h following the administration of a single oral dose of 1000 mg cefadroxil. It was demonstrated that the concentrations in renal tissue were within the range from 14.2 to 115 micrograms/g tissue, while the serum levels varied from 11.6 to 63.3 micrograms/ml serum. A statistically significant correlation between serum levels and renal tissue levels can be demonstrated. The correlation of the distribution ratio: serum level/tissue level to serum creatinine level proved to be a linear regression, i.e. the distribution quotient decreased if the serum creatinine level increased. This means that the renal tissue level of cefadroxil in comparison to serum level will be lower in patients with renal impairment. However, even with much impaired renal function the renal tissue level exceeded the minimum inhibitory concentration for the most relevant pathogens.

Cefetamet pivoxil, an oral third generation cephalosporin, was evaluated in 218 hospitalized patients with complicated urinary tract infections. Among these patients, 28 (13.1%) were suffering from concomitant diabetes: 25 of these patients were matched with 25 non-diabetic patients and for each pair, the age +/- 2 years, sex, complicating factors, etc. had to be identical. All patients received 2000 mg cefetamet pivoxil daily for 10 days. The predominant pathogen was E. coli; 18 in the diabetic group, 15 among non-diabetics. Comparison of the therapeutic results showed that the bacteriological eradication rate was similar in diabetic and non-diabetic patients, 92% and 87.5%, respectively. There was a similar improvement in pyuria, and therapeutic response was equal in diabetic patients as in non-diabetic patients. No unwanted effects on renal function were observed in the high-risk diabetic group.

The effect of two cephalosporins, cefadroxil and cefalexine, was in vitro studied by using two models of regulation of the IgE production in healthy humans, e.g. the induction of CD23-antigens on B-cells and the IgE synthesis in cell culture supernatants after stimulation by recombinant interleukin-4. Cefadroxil clearly inhibited CD23 membrane expression on normal human B-lymphocytes. In the same way, this cephalosporin blocked up to 90% of the in vitro interleukin-4-dependent IgE production by normal peripheral blood mononuclear cells. Cefalexine was unable to do the same. There results suggest that cefadroxil interplays with the regulation processes of the IgE production in humans.

The incidence of AAD in the probiotic group was 10.8% compared to 15.6% in the placebo group, the difference being statistically non-significant (p = 0.19). The relative risk for AAD was 0.7 with the 95% CI being 0.4 to 1.2. The diarrhoea duration in the probiotic group was two days with an interquartile range of 1- 3 days and was significantly less (p = 0.01) than the placebo group which was four days with an interquartile range of 3 - 5.5 days. Subgroup analysis of subjects with AAD showed that the incidence of severe diarrhoea (watery stools) was 96% in the placebo group (25 out of 26) compared to 31.6% (6 out of 19) in the probiotic group and this difference was significant statistically (p < 0.001). Four mild, non-serious, adverse events were detected (2.0%) in the probiotic group but there were none in the placebo group.

Twelve healthy volunteers received cefatrizine orally at doses equal to 500 mg every 12 h for 5 days. Cefatrizine was assayed by high performance liquid chromatography in plasma and urines collected after the first and/or the last administration. Cefatrizine absorption was rapid; its peak plasma level was reached at time 1.79 +/- 0.07 h following the first dose, it was equal to 7.37 +/- 0.31 micrograms.ml-1. Its apparent elimination half-life was equal to 1.50 +/- 0.05 h, it explains the lack of accumulation with time during multiple administrations every 12 hours. Comparisons between peak plasma concentration and area under curves following the first and last dosing showed significant (p less than 0.01) but weak (close to 15%) reduction of these 2 parameters with time which could be explained by a slight reduction of cefatrizine absorption with time. In conclusion, cefatrizine does not accumulate when administered repeatedly at a dose equal to 500 mg every 12 h in young adult, and its pharmacokinetics is virtually linear with time.

In vitro susceptibility testing of 28 strains of Eikenella corrodens by the agar dilution technique showed that all strains were uniformly susceptible to penicillin, ticarcillin, cefoxitin, cefotaxime, N-formimidoyl thienamycin, and moxalactam and resistant to clindamycin and cefadroxil. Cefoperazone, piperacillin, and mezlocillin showed good activity, with some strains relatively resistant. Bacampicillin and cefamandole showed relatively poor activity.

Thirty-two patients with pharyngitis were randomly assigned to receive either 30 mg/kg of cefadroxil every 24 hours orally or 15 mg/kg of penicillin V potassium every eight hours orally for ten days. Sera for antistreptolysin-O, streptozyme, and anti-DNAase were compared before and after treatment. Twenty patients finished the study and had a confirmed throat culture for the group A streptococcus and at least one fourfold antibody rise. Of these 20 patients, seven of eight in the penicillin group and all 12 in the cefadroxil group were cured at the end of therapy. One patient in the penicillin group had a positive culture at the end of therapy; one patient in each group was recolonized at follow-up culture 10 to 20 days after ending therapy. Seven other patients who finished the study had a positive throat culture but no antibody response and were presumed carriers; these included five in the penicillin and two in the cefadroxil group. One of these presumed carriers had a persistent infection and relapsed two days after the end of therapy. Both therapies appeared to be equally successful and no serious side effects occurred.

The in vitro activity of loracarbef, penicillin V, cefaclor and cefadroxil against log and stationary phase cultures of group A streptococci was compared. MICs and MBCs were determined with the broth dilution method and by a modified agar plate dilution technique where the beta-lactams were inactivated after the MICs were determined allowing inhibited but not killed organisms to grow on further incubation. The MICs of loracarbef and the two cephalosporins were 16-32 times higher than those of penicillin V. In plate dilution the MBC/MIC ratios of all agents were < or = 2 for log phase cultures. With stationary phase cultures, especially in the broth dilution test, the MBC/MIC ratios of loracarbef and the two cephalosporins were > or = 32 for a large number of strains. The phenotype response of stationary phase cultures to beta-lactam antibiotics may not only be related to the physiological status of the streptococci, to the culture conditions and to the beta-lactam under test. The present investigation indicated that the phenotypic response was also an intrinsic property of certain strains.

Eleven new 7-[2-(dihydro-5-substituted-6-thioxo-2H-1,3,5-thiadiazine-3( 4H)-yl)-2- (4-hydroxyphenyl)acetamido]-3-methyl-3-cephem-4-carboxylic acid derivatives were synthesized by the reaction of cefadroxil monohydrate, formaldehyde and substituted potassium dithiocarbamate. Their structures have been elucidated by spectral data and elementary analysis. The title compounds were tested for antimicrobial activity in vitro against gram-positive bacteria (Staphylococcus aureus, Streptococcus faecalis), gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa) and yeast-like fungi (Candida albicans, C. parapsilosis, C. stellatoidea, C. pseudotropicalis) in comparison with cefadroxil monohydrate. The activity of compounds 1 and 10 against S. aureus (MBC: 37.5 micrograms/ml) and compound 1 against E. coli (MBC: 75 micrograms/ml) were found to be the same as cefadroxil monohydrate. Compounds 1 and 10 were more effective than cefadroxil monohydrate against S. faecalis with 25 and 37.5 micrograms/ml MBC values, respectively. None of the compounds and cefadroxil monohydrate proved to be effective against P. aeruginosa (MBC: greater than 100 micrograms/ml). While cefadroxil monohydrate had no activity against yeast-like fungi, compounds 9 and 10 were significantly effective against yeast-like fungi (MFC: 37.5 micrograms/ml).

A double-blind, randomized clinical trial was carried out to compare the effectiveness of twice daily versus once daily administration of the cephalosporin, cefatrizine, in paediatric outpatients with bacterial infection of the respiratory tract. Thirty children were studied, aged 7 years 2 months (range, 4-12 years). They were given 75 mg/kg.day cefatrizine either once daily or twice daily at 12 h intervals for 8 days. Fever, clinical symptoms, bacterial eradication and overall tolerance were evaluated. No significant differences were observed between once daily or twice daily administration. This is in agreement with other studies carried out on adults. It is concluded that cefatrizine may be given to paediatric out-patients for the treatment of bacterial infection of the respiratory tract only once daily with good clinical and overall results.

Antibiotic resistance in avian bacterial pathogens is a common problem in the Bangladesh poultry industry. The aim of the present study was to provide information on the present status of antibiotic resistance patterns in avian pathogenic Escherichia coli in Bangladesh. Of 279 dead or sick poultry of different ages, 101 pathogenic E coli strains isolated from broilers and layer hens with colibacillosis infections were screened to determine phenotypic expression of antimicrobial resistance against 13 antibiotics used in both veterinary and human medicine in Bangladesh. Of 101 pathogenic E. coli isolates, more than 55% were resistant to at least one or more of the tested compounds, and 36.6% of the isolates showed multiple-drug-resistant phenotypes. The most common resistances observed were against tetracycline (45.5%), trimethoprim-sulphamethoxazole (26.7%), nalidixic acid (25.7%), ampicillin (25.7%), and streptomycin (20.8%). Resistance to ciprofloxacin (12.9%), chlormaphenicol (8.9%), nitrofurantoin (2%), and gentamicin (2%) was also observed, and none of the isolates were resistant to tigecycline as well as extended spectrum beta-lactamase (ESBL) producers. One isolate was resistant to cefuroxime (1%), cefadroxil (1%), and mecillinam (1%) but was not an ESBL producer. Resistance rates, although significant in Bangladeshi isolates, were found to be lower than those reported for avian isolates from the Republic of Korea and clinical, avian, and environmental isolates from Bangladesh. The high level of antibiotic resistance in avian pathogens from Bangladesh is worrisome and indicates that widespread use of antibiotics as feed additives for growth promotion and disease prevention could have negative implications for human and animal health and the environment.

1. The oral cephalosporins: cefatrizine and cephaloglycine inhibit the L-leucine absorption in vivo on rat jejunum. 2. This inhibition is dose and time dependent and the effect is irreversible. 3. These antibiotics have a systemic effect on L-leucine absorption. 4. The inhibition of these antibiotics affect only leucine transport, without affecting the diffusion. 5. Cefatrizine and cephaloglycine inhibit the basolateral (Na(+)-K+) ATPase activity in rat jejunum.

Ceftibuten and cyclacillin were recognized by PEPT1 with affinity constants comparable to those of natural dipeptides (K(i) = 0.3 and 0.5 mM, respectively). Cefadroxil, cefamandole, cephradine, cefaclor, cefuroxime-axetil, cefixime, cephalotin, cephalexin and ampicillin also interacted with PEPTI (K(i) = 7-14 mM). In contrast, cefapirin, cefodizime, cefuroxime, cefmetazole, ceftazidime, benzyl-penicillin, ceftriaxone, cefpirome, cefotaxime, cefepime, cephaloridine and cefsulodin displayed no affinity to the transport system (K(i) > 20 mM). The uptake into the cells and the transepithelial flux was highest for those beta-lactam antibiotics, which showed the strongest inhibition of [14C]Gly-Sar transport (p < 0.0001). Exceptions were cefuroximaxetil and cephalotin.

The in-vitro activity of ceftibuten was compared with cefuroxime and cefadroxil against 475 clinically-significant, epidemiologically-distinct isolates of Gram-negative bacilli: 170 from blood, 212 from urine and 93 from a supplementary collection of multiply-resistant strains known to have resistance plasmids, to have caused sporadic or epidemic nosocomial infection, or both. Ceftibuten MICs ranged from 0.003 to greater than 32 mg/l, with a modal MIC of 0.01 mg/l: 95% of all isolates had ceftibuten MIC values of less than or equal to 8 mg/l, the sensitivity breakpoint suggested by the manufacturer. Ninety per cent of isolates had MICs of less than or equal to 1 mg/l and 49% had MICs of less than or equal to 0.03 mg/l. All isolates of Klebsiella, Serratia, Proteus and Providencia spp., and Morganella morganii had MIC values of 8 mg/l or less. Only two of 124 isolates of Escherichia coli tested, and only one of 23 Citrobacter spp., had MICs of greater than 8 mg/l (16, 16 and greater than 32 mg/l respectively). Resistance MIC greater than 16 mg/l) was more frequent among Enterobacter and Acinetobacter spp. Thirteen of 52 Enterobacter spp., and seven of 18 Acinetobacter calcoaceticus had MICs of at least 32 mg/l. MIC ranges, modal MICs and MIC90s indicated that ceftibuten was, with the exception of only two strains, consistently more active in-vitro than cefuroxime, which was in turn more active than cefadroxil.

Intracerebral microdialysis was used to measure unbound concentrations of cefadroxil in rat blood, striatum extracellular fluid (ECF) and lateral ventricle cerebrospinal fluid (CSF). The distribution of cefadroxil in brain was compared in the absence and presence of probenecid, an inhibitor of OATs, MRPs and OATPs, where both drugs were administered intravenously. The effect of PEPT2 inhibition by intracerebroventricular (icv) infusion of Ala-Ala, a substrate of PEPT2, on cefadroxil levels in brain was also evaluated. In addition, using an in vitro brain slice method, the distribution of cefadroxil in brain intracellular fluid (ICF) was studied in the absence and presence of transport inhibitors (probenecid for OATs, MRPs and OATPs; Ala-Ala and glycylsarcosine for PEPT2).

Bacteriologic treatment success rates for patients in cefadroxil and penicillin groups were 94% and 86%, respectively. However, among patients classified clinically as likely to have bona fide GABHS pharyngitis, there was no difference in bacteriologic treatment success rates in cefadroxil and penicillin groups (95% and 94%, respectively). Among patients classified clinically as likely to be streptococcal carriers, bacteriologic treatment success rates in cefadroxil and penicillin groups were 92% and 73%, respectively. The presence of beta-lactamase and/or bacteriocin-producing pharyngeal flora had no consistent effect on bacteriologic eradication rates among patients in either penicillin or cefadroxil treatment groups or among patients classified as having either GABHS pharyngitis or streptococcal carriage.

Cefadroxil, a cephalosporin antibiotic, is a substrate for several membrane transporters including peptide transporter 2 (PEPT2), organic anion transporters (OATs), multidrug resistance-associated proteins (MRPs), and organic anion transporting polypeptides (OATPs). These transporters are expressed at the blood-brain barrier (BBB), blood-cerebrospinal fluid barrier (BCSFB), and/or brain cells. The effect of these transporters on cefadroxil distribution in brain is unknown, especially in the extracellular and intracellular fluids within brain.

This study was performed to characterize the transport of the endogenous photosensitizer delta-aminolevulinic acid in tumor cells of the extrahepatic biliary duct. Uptake of [(3)H]delta-aminolevulinic acid into human cholangiocarcinoma SK-ChA-1 cells was linear for up to 10 min, independent of a Na(+) gradient, but stimulated 3- to 4-fold by an inwardly directed H(+) gradient. Uptake of delta-aminolevulinic acid was mediated by a single transport system with an apparent affinity (K(t)) of 2.1 mM and a maximal velocity (V(max)) of 60.1 nmol. 10 min(-1). mg of protein(-1). Glycylsarcosine, alanylalanine, and cefadroxil strongly inhibited the [(3)H]delta-aminolevulinic acid uptake with K(i) values of 1.3, 0.2, and 3.6 mM, respectively. In contrast, gamma-aminobutyric acid, glycine, L-glutamic acid, and L-aspartic acid (all 10 mM) had no effect on the total [(3)H]delta-aminolevulinic acid uptake, neither at pH 6.0 nor at pH 7.5. Applying a Dixon type of experiment and the ABC test revealed that glycylsarcosine and delta-aminolevulinic acid are transported via the same system, PEPT1. Treatment of the cells with phorbol 12-myristate 13-acetate, a phorbol ester that activates protein kinase C, resulted in a significant inhibition of the transport rate. This inhibition could be blocked by cotreatment with staurosporine. We conclude that delta-aminolevulinic acid is transported by the H(+)/peptide cotransporter PEPT1 into epithelial cells of the extrahepatic biliary duct. delta-Aminolevulinic acid can be accumulated specifically in bile duct tumor cells before photodynamic therapy.

In our study, out of 449 Enterobacteriaceae strains isolated between 1985 and 1990, 16 strains (3 Proteus, 6 nontyphoidal Salmonella, 7 Escherichia coli) were resistant both buy duricef to Ampicillin- Sulbactam and Amoxycillin-Clavulanic acid associations. The activity profiles of the beta-lactamases produced by these resistant strains are described. Sarcina lutea ATCC 9341 was used as test strain. The effect of the enzymatic filtrate against beta-lactam antibiotics: Ampicillin, Cloxacillin, Cefadroxil, Cefuroxime, Cefotaxime, Ceftriaxone, was followed up. The enzyme types were established according to the ability of inactivating the tested antibiotics. Penicillins and cephalosporins were inactivated by these enzymes, except for Carbenicillin and Oxacillin. These beta-lactamases were resistant to Sulbactam and Clavulanic acid. In the studied Salmonella strains they are plasmidic codified, demonstrating that they belong to a new beta-lactamase class.

Nephronia or focal acute nephritis corresponds to a localized inflammatory non-liquefactive kidney infection which may involve parenchyma of one or more renal lobes. It has been suggested that nephronia buy duricef is part of the spectrum of upper urinary tract infections between acute pyelonephritis and renal abscess. It is associated with a prolonged clinical course, higher levels of inflammatory markers and an increased risk of renal scarring, compared to pyelonephritis. Ultrasound plays a useful role. Nephronia is an under-diagnosed condition, thus, clinical suspicion is important for early diagnosis and appropriate treatment. We present three paediatric cases, and a review of the literature.

The fate of four antimicrobials (cefadroxil, CFD; metronidazole, METRO; trimethoprim, TRI; sulfamethoxazole, SMX) was studied in Lemna minor systems and the role of different mechanisms on their removal was evaluated. All micropollutants were significantly removed in batch experiments with active Lemna minor; the highest removal was observed for CFD (100% in 14 d), followed by METRO (96%), SMX (73%) and TRI (59%) during 24 d of the experiment. Calculation of kinetic constants for hydrolysis, photodegradation, sorption to biomass and plant uptake revealed significant differences depending on the compound and the studied mechanism. For METRO, TRI and SMX the kinetic constants of plant uptake were by far higher comparing to those of the other mechanisms. The transformation products of antimicrobials were identified using UHPLC-QToF-MS. Two were the main degradation pathways for TRI; hydroxylation takes place during both phyto- and photodegradation, while demethylation occurs only in absence of Lemna minor. The operation of a continuous-flow duckweed system showed METRO and TRI removal buy duricef equal to 71±11% and 61±8%, respectively. The application of mass balance and the use of published biodegradation constants showed that plant uptake and biodegradation were the major mechanisms governing METRO removal; the most important mechanism for TRI was plant uptake.

The pharmacokinetics of cefadroxil suspension were studied in 30 children, 13 months to 12 years of age (mean age, 5.7 years). Average peak concentrations in serum of 11 to buy duricef 14 mug/ml and of 7 to 10 mug/ml after 15- and 10-mg/kg doses, respectively, were not substantially affected by the feeding status. The serum half-life values were 1.3 to 1.5 h. Cefadroxil was detected in saliva of all children 2 h after 15-mg/kg doses: the levels ranged from 0.17 to 2.6 mug/ml (mean, 0.46 mug/ml). The average concentrations in urine were 1,700 and 2,620 mug/ml at 0 to 2 and 2 to 4 h, respectively, after 15-mg/kg doses. In a randomized controlled study of 50 children with impetigo, cefadroxil was as effective as penicillin G in curing existing lesions and in preventing development of new lesions. Cefadroxil may be useful for therapy of mucocutaneous and urinary tract infections in infants and children.

The Delvotest method detection limits per manufacturer's instructions at a fixed reading time of 3 h for 24 antimicrobial agents were determined in ewe milk by photometric measurement. For each drug, eight concentrations were tested on 20 ewe milk samples from individual ewes. Detection limits, determined by means of logistic regression models, were (microg/kg): 3, amoxycillin; 2, ampicillin; 18, cloxacillin; 1, penicillin "G"; 34, cefadroxil; 430, cephalosporin "C"; 40, cephalexin; 20, cefoperazone; 33, Ceftiofur; 18, cefuroxime; 6100, streptomycin; 1200, gentamycin; 2600, neomycin; 830, erythromycin; 100, tylosin; 180, doxycycline; 320, oxytetracycline; 590, tetracycline; 88, sulfadiazine; 44, sulfamethoxazole; 140, sulfametoxypyridazine; 48, sulfaquinoxaline; 12,000, chloramphenicol; and 290, trimethoprim. Whereas the beta-lactam antibiotics, sulphonamides, and tylosin were detected by Delvotest method at levels equal to those of maximum residue limits, its sensitivity needs to be enhanced to detect aminoglycosides, tetracyclines, streptomycin, chloramphenicol, and trimethoprim residues in ewe milk or to develop an integrated residue detection system for ewe milk with different sensitive buy duricef microorganisms for each group of antiinfectious agents.

A new chemiluminescence reaction, the luminol-Cu(2+) reaction, was investigated for the determination of thirteen (13) cephalosporin antibiotics, namely cefalexin, cefadroxil, cefradine, cefazolin sodium, cefaclor, cefuroxime axetil, cefotaxime sodium, cefoperazone sodium, ceftriaxone sodium, ceftazidime, cefetamet pivoxil hydrochloride, cefixime, and cefpodoxime. It was found that, without adding any special oxidant, strong chemiluminescent (CL buy duricef ) signal could be produced from the reaction of the alkaline luminol with the above-mentioned antibiotics in the presence of Cu(2+). The experimental conditions for the reaction were carefully optimized with flow-injection mode. The detection limits are 0.3 ng/mL cefalexin, 3 ng/mL cefadroxil, 0.3 ng/mL cefradine, 0.02 μg/mL cefazolin sodium, 0.8 ng/mL cefaclor, 0.02 μg/mL cefuroxime axetil, 5 ng/mL cefotaxime sodium, 0.02 μg/mL cefoperazone sodium, 0.8 ng/mL ceftriaxone sodium, 1 ng/mL ceftazidime, 0.08 ng/mL cefetamet pivoxil hydrochloride, 0.8 ng/mL cefixime, and 2 ng/mL cefpodoxime. The proposed method was validated by direct application to commercial formulations and spiked milk samples containing cefradine. A possible reaction mechanism is also discussed.

Cefatrizine (SK & F 60771; BL--S640), like most other phenylglycine-type cephalosporins, has a tendency to lose potency in aqueous solutions and in normal sera even at low temperatures. Cefatrizine can be stabilized during storage by sodium metabisulphite (Na2S2O5), a reducing agent partially in tap water, better in deionized water, and to a lesser degree in citric acid-phosphate buffer (pH 6). Although this partial stabilizing effect of sodium metabisulphite is temperature-dependent, storage at 4 degrees C gives better results than storage in the frozen state (-20 degrees C). In these aqueous solutions and in sera, the potency of cefatrizine can be preserved even at room temperature for up to four weeks by the addition of 0.1 ml of 2 N hydrochloric acid to each 2 ml of aqueous solutions buy duricef or sera.

The antimicrobial buy duricef susceptibilities of 1385 clinical isolates of Streptococcus pneumoniae obtained from 25 laboratories across Austria between December 1994 and January 1996 were tested. Minimal inhibitory concentration (MIC) values were determined in tests with penicillin, amoxycillin, amoxycillin/clavulanate, ceftriaxone, cefodizime, cefpirome, cefotaxime, cefpodoxime, cefadroxile, azithromycin, clarithromycin, josamycin and roxithromycin by the agar-dilution method. A total of 40 isolates (2.9%) demonstrated intermediate resistance (MIC 0.125-1 microg/ml) and 28 isolates (2.0%) had high-level resistance (MIC > or = 2 microg/ml) to penicillin. Excepting cefadroxil, with an MIC90 of 2 microg/ml, all other tested beta-lactams had MIC90s of 0.03-0.06 microg/ml. Penicillin-resistant strains were much more likely to be also resistant to the other beta-lactams. The macrolides proved to be very active compounds against pneumococci with MIC90s of 0.06 microg/ml (clarithromycin) and 0.25 microg/ml (all other macrolides). Regional differences within Austria with regard to antimicrobial resistance were not observed.

Cefadroxil is a semi-synthetic first generation oral cephalosporin with advantages of almost 100% excretion in the urine within six hours and low cost. It was freely available in the formulary and we undertook an audit of its usage, the indications cited, underlying clinical conditions and relevant microbiology in 106 cases. Following the audit, cefadroxil was restricted, available only on the advice buy duricef of a microbiologist. Subsequently, another survey was carried out to document the reasons for requesting cefadroxil by clinical staff and the alternatives suggested in each case. The first survey revealed that in 91% cases, cefadroxil had been used inappropriately. The second suggested that the reasons for requesting it were based upon misunderstanding by clinicians as to its value. The only useful indication identified was the treatment of susceptible bacteruria in pregnancy. A suitable oral alternative could be identified for all other cases where an antibiotic was indicated. We believe that first generation cephalosporins such as cefadroxil have little role in hospital practice and should therefore be restricted.

MDL 19,592 is a new semisynthetic cephalosporin with a good therapeutic potential against Gram-positive bacterial infections when administered orally or parenterally. In the oral treatment of benzylpenicillin-resistant Staphylococcus aureus infections in mice, MDL 19,592 was superior to buy duricef cephalexin, cephradine, cefaclor, cefadroxil and cefroxadine. These in vivo results reflect the in vitro superiority expressed by MDL 19,592 over the other oral cephalosporins against staphylococci. Additionally, MDL 19,592 orally was superior to cefazolin and cephalothin administered subcutaneously and to a number of penicillinase-resistant penicillins given orally or subcutaneously in the treatment of S. aureus mouse infections. MDL 19,592 killed S. aureus cells at the same or faster rate than did cephalexin or cephradine. As compared to cephalexin, MDL 19,592 was marginally superior in vitro against Streptococcus pyogenes and Streptococcus pneumoniae. In vivo, MDL 19,592 was significantly the more effective of the two against S. pyogenes and marginally more effective against S. pneumoniae. Against Gram-negative organisms, with the exception of Haemophilus influenzae, cephalexin was the more potent of the two antibiotics both in vitro and in vivo. Administered orally to mice, MDL 19,592 was absorbed as rapidly as cephalexin with both drugs attaining similar concentrations in the blood. MDL 19,592, like cephalexin, was minimally bound by mouse serum.

We studied the effects of three cephalosporins (cefadroxil, cefaclor, cephalexin) on an in Zyrtec D Review vitro model of human mononuclear cell proliferation in response to polyclonal mitogens. Cefadroxil, and to a lesser extent cefaclor and cephalexin, induced a decrease of proliferative responses to phytohaemagglutinin and concanavalin A. This decrease was not due to a direct effect on lymphocytes, but depended on the presence of adherent monocytes in the cultures. Cephalosporins stimulated the release of prostaglandins E2 by monocytes, generating a suppressive activity. Cefadroxil and cephalexin were in vivo given to Brown-Norway rats sensitized to DNP-OVA to induce a primary and secondary IgE specific response. The administration of cefadroxil provoked a clear decrease of the secondary IgE response. As the IgE production closely depends on T suppressor cells, we hypothesize that cefadroxil could interfere with that production by stimulating a suppressor cell activity linked to an increased PGE2-release.

Sultamicillin is the tosylate salt of the double ester of sulbactam plus ampicillin. Sulbactam is a semisynthetic beta-lactamase inhibitor which, in combination with ampicillin, extends the antibacterial activity of the latter to include some beta-lactamase-producing strains of bacteria that would otherwise be resistant. The combination of sulbactam plus ampicillin for parenteral use has previously been shown to be clinically and bacteriologically effective in a variety of infections. The chemical linkage of sulbactam and ampicillin has now produced an orally effective compound, sultamicillin, with antibacterial activity and clinical efficacy which are similar to those of the parenteral formulation. Sultamicillin has been shown to be clinically effective in non-comparative trials in patients with infections of the respiratory tract, ears, nose and throat, urinary tract, skin and soft tissues, as well as in obstetric and gynaecological infections, and in the treatment of gonorrhoea. In a small number of controlled trials, sultamicillin has shown comparable clinical efficacy to phenoxymethyl penicillin (penicillin V) and to amoxycillin (alone and in combination with clavulanic acid) in the treatment of paediatric streptococcal pharyngitis and acute otitis media, respectively; to cefaclor in the treatment of acute otitis media in adults; and to bacampicillin, cloxacillin and flucloxacillin plus ampicillin in skin and soft tissue infections in adults, children and adult diabetic patients, respectively. Sultamicillin was superior in efficacy to bacampicillin in the treatment of chronic respiratory infections, to cefaclor in the treatment of acute otitis media in adults, and to cefadroxil in the treatment of patients with complicated urinary tract infections. However, in single-dose treatment of uncomplicated gonorrhoea, sultamicillin (1500mg plus probenecid 1g) was inferior to a 2g intramuscular dose of spectinomycin. While in several studies the incidence of diarrhoea associated with Combivir Dosage Children sultamicillin was greater than that with comparative antibacterials, sultamicillin-associated diarrhoea was generally mild and transitory, although occasionally severe enough to necessitate discontinuation of treatment. Further studies in larger groups of patients are needed to clarify the therapeutic efficacy and safety of sultamicillin in comparison with other antibacterial regimens, and to determine the optimum single dosage for the treatment of gonorrhoea. Nonetheless, sultamicillin appears to provide a similar pharmacodynamic and pharmacokinetic profile to that of parenteral sulbactam plus ampicillin and, as such, will extend the therapeutic efficacy of ampicillin, with the further advantage of allowing treatment of patients with an oral formulation, thus avoiding the potentially adverse clinical and financial effects of prolonged parenteral therapy.

A fluorescent spot test method for specific detection of microbial beta-lactamases as previously published (K. C. S. Chen, J. S. Cleocin 100 Mg Knapp, and K. K. Holmes, J. Clin. Microbiol. 19:818-825, 1984) was improved by the use of a fluorescence developer solution. The fluorescence developer solution used in this study consisted of 0.78 M sodium tartrate buffer containing 12% formaldehyde at a final pH of 4.5. An addition of 1 volume of fluorescence developer solution to 5 volumes of ampicillin or cephalex substrate solution incubated with beta-lactamase-producing organisms, followed by heating the mixture at 45 degrees C for 10 min resulted in enhancement of fluorescence of the end products of beta-lactamase activity. This provides a more sensitive assay for microbial beta-lactamases and offers the potential for direct detection of beta-lactamases in clinical specimens.

In acute pyelonephritis renal scarring may be decreased by immediate antibiotic therapy. Unfortunately in children there is often a delay in starting treatment, which increases the likelihood of renal scarring. In rodents immediate antibiotic therapy is effective for preventing renal scar formation resulting from experimentally induced pyelonephritis. However, the same treatment beginning 72 hours after infection does not prevent Acne Medication Duricef renal scarring in this paradigm. We examined whether delayed administration of the nonsteroidal anti-inflammatory agent ibuprofen only or combined with antibiotics suppresses renal scarring in a model of ascending pyelonephritis in rats.

The efficacy and safety of cefadroxil in eradicating localized skin and skin-structure infections of the foot were Zofran Iv Dose investigated in a retrospective chart review of 222 consecutive patients from two private practices seen over a 10-year period. Of the 189 patients for whom follow-up data were available, 187 (99%) received cefadroxil 500 mg twice daily, and 2 patients (1%) received 250 mg twice daily. The duration of therapy was 2 weeks or less in 87% of patients, with a median duration of therapy of 11.4 days (range, 5 to 35 days). Of the 189 clinically evaluable patients, 179 (95%) achieved a favorable clinical response to treatment; of the 57 patients with microbiologic cultures, 54 (95%) experienced a satisfactory bacteriologic response to therapy; no adverse events related to cefadroxil therapy were identified during the review. The overall results from this retrospective study suggest that cefadroxil is an effective agent with a favorable safety profile for the treatment of skin and skin-structure infections of the foot.

In recent years, patients allergic to amoxicillin (AX) but with good tolerance of penicillin G (PG) have been described. It has been suggested that the epitope implicated in this type of sensitization might be located on the side-chain of the AX molecule. Thus, cross-reactivity between AX and cephadroxil (CEPH), a cephalosporin which shares an identical side-chain with AX, is suspected. This study aimed to demonstrate clinical cross-reactivity between AX and CEPH in patients allergic to AX and showing good tolerance of PG. In 76 of 576 subjects with suspected allergic reaction to PG and/or AX, the diagnosis of allergy was confirmed. All of these had specific IgE to PG, penicillin V, or AX, and/or positive skin tests to PPL (penicilloyl-polylysine), or MDM (minor determinant mixture), or PG, or AX, and/or positive challenge tests with PG and/or AX. Sixteen subjects (21%) allergic to AX (11 with positive skin test and five with positive challenge test to AX) and good tolerance of PG (all with negative parenteral challenge test) were selected. These 16 patients were subsequently challenged with CEPH (up to 500 mg). Fourteen patients tolerated CEPH, and two (12%) had an immediate allergic reaction. Our study indicates that allergy to the side-chain of aminopenicillins seems to have little clinical relevance in patients with allergic reactions to aminopenicillins but with good tolerance of PG, as 88% of patients with this clinical characteristic tolerate a cephalosporin which shares an identical side-chain. It seems that IgE from most of these patients recognizes an epitope different from the side- Neurontin 50 Mg chain and the beta-lactam ring.

The present study describes the application of CE to investigate the interaction between a cephalosporin, cefadroxil and different metal ions. This study aims at quantifying the interaction of cefadroxil with Zn(2+), Al(3+), Fe(3+), Cu(2+) and Co(2+) ions using the effective electrophoretic mobility as a parameter for calculation of the reaction association constant (K). For this purpose, the electrophoretic mobilities of cefadroxil at different metal ion concentrations in citrate buffer pH 3.6 were determined. A mathematical model to calculate the association constant between cefadroxil and metal ions was used. The results showed that a strong change in the cefadroxil electrophoretic mobility was observed by increasing the metal ion concentrations. The results revealed that by increasing the concentration of metal ions in the running buffer the degree of complexation increases too. On the basis of the results, the strength of the interaction of cefadroxil with the investigated metal ions follows the order Zn(2+)>Cu(2+)>Co(2+)>Fe(3+)>Al(3+). The association Cymbalta Substitute Generic constant of the investigated reactions ranged from 451.57 to 1546.52 L/mmol. The results indicate that it is possible to characterize the interaction between cefadroxil and metal ions quantitatively using CE.

The luminol-bovine serum albumin chemiluminescence system Zanaflex Tizanidine Medication was proposed for the first time. It was found that the hydrophilic luminol bound to the hydrophilic domain at Trp(134) of BSA with accelerating the electrons transferring rate of excited 3-aminophthalate, which led to the enhancement CL intensity of luminol at 425 nm. The increment of chemiluminescence intensity was proportional to the concentrations of bovine serum albumin from 5.0 × 10(-11) to 1.0 × 10(-8)mol L(-1) with the linear equation of ΔI=7.47 C(BSA)+4.89 (R(2)=0.9950). Based on the remarkable quenching effect of cephalosporin on the luminol-bovine serum albumin chemiluminescence system, the interaction of bovine serum albumin-cephalosporin was studied by flow injection-chemiluminescence method. A valuable model for studying the interaction of bovine serum albumin-cephalosporin was constructed and the formula lg[(I(0)-I)/I]=lg K(D)+n lg[D] was obtained. The binding parameters calculated by the model did agree very well with the results obtained by fluorescence quenching method. The major binding force of bovine serum albumin with cephalosporins was the hydrophobic effect. The binding ability of cephalosporin analogues to bovine serum albumin followed the pattern: cefoperazone, ceftriaxone and cefotaxime>cefuroxime and cefaclor>cefadroxil, cefradine and cefazolin, which was close to the order of their antibacterial ability. Using flow injection chemiluminescence method also obtained the stoichiometric ratio, the average of association constant K(P) and dissociation degree α of luminol-bovine serum albumin were 1:1, 1.12 × 10(7)L mol(-1) and 0.086, respectively.

Data are presented on the effect of ethanol on the intestinal absorption and excretion in rats of two beta-lactam antibiotics, cephalexin (CFX) and cefadroxil (CFD). A recirculating perfusion technique within an antibiotic concentration range of 0.5 to 50 mM was used. Ethanol was administered either in an acute form into the intestine or in a chronic form as a 15% drinking solution for 2 months. The results are normalized in relation to the metabolic body weight, intestinal length, and osmotic conditions. Acute ethanol treatment decreases the antibiotic absorption; biliary excretion of CFD is increased, while urinary excretion of CFX is lowered. Chronic treatment shows slight negative effects on the absorption of CFX and CFD. Results are interpreted on the basis of the effect of ethanol on biological membranes. Enhanced urinary excretion after acute ethanol treatment, as well as differences between transport mechanisms, are invoked to explain these effects.

To explore the feasibility of targeting human tumor cells via their transport systems, dipeptide uptake was studied in the human fibrosarcoma cell line HT1080 and the human fibroblast cell line IMR-90 by the use of hydrolysis-resistant glycylsarcosine (Gly-Sar). The uptake of [14C]Gly-Sar into HT1080 was time dependent. Kinetic analysis of the concentration dependence of the initial rate of [14C]Gly-Sar uptake showed that a carrier-mediated transport system with a K(m) of 11.4 +/- 3.3 mM and V(max) of 26.8 +/- 4.0 (nmol/15 min/mg protein) and a nonsaturable component (k(d) of 0.80 microl/15 min/mg protein) were responsible for the dipeptide uptake by HT1080 cells. The optimal pH for the maximal uptake was around 6.0. [14C]Gly-Sar uptake was inhibited by various di- and tripeptides and peptide-mimetic drugs, such as bestatin and cefadroxil. [14C]Gly-Sar uptake was not affected by the presence of amino acids or tetra- or pentapeptides. The uptake of cefadroxil was reduced significantly by unlabeled Gly-Sar. Moreover, Gly-Gly and Gly-Leu produced an increase in the apparent K(m) of the uptake of Gly-Sar without altering V(max). On the other hand, dipeptide uptake by IMR-90, which is a normal diploid cell line (not malignant), showed no saturable transport. These results suggest that HT1080 cells take up dipeptides via a pH-dependent transporter. This is the first report showing that a dipeptide transport system, which is similar but not identical to the well-characterized oligopeptide transporters PepT1 and PepT2, exists in fibroblast-derived tumor cells but not in normal fibroblasts. The present finding could be the basis of a novel strategy for the specific delivery of oligopeptide-mimetic anticancer drugs into tumor cells.
