We retrospectively evaluated 100 consecutive MM patients treated with bortezomib-based therapies at the Roswell Park Cancer Institute for development of herpes zoster. Frontline and relapsed/refractory patients were included, and patients received bortezomib alone or in combination with agents such as doxorubicin, melphalan, or dexamethasone. All patients received >4 weeks of acyclovir prophylaxis (400 mg twice daily), which was initiated prior to starting treatment with bortezomib and discontinued 4 weeks following bortezomib.

Although addition of gemcitabine to paclitaxel and epirubicin and cyclophosphamide chemotherapy does not improve pCR, sequencing chemotherapy so that taxanes are received before anthracyclines could improve pCR in standard neoadjuvant chemotherapy for breast cancer.
Plerixafor is a recently introduced agent used to improve peripheral blood stem cell (PBSC) mobilization in patients with hematologic malignancies. However, some patients still cannot mobilize adequately even with plerixafor.
Systemic lupus erythematosus (SLE) is a complex autoimmune disease characterized by autoantibody production, complement activation, and deposition of immune complexes in tissues and organs. SLE can involve any region of the visual system. Although ocular manifestations are not part of the classification criteria for SLE, they can be observed in up to one-third of the patients with SLE. They are rarely reported at the time of disease onset. Retinal vasculitis is usually associated with active generalized disease. Due to its low frequency, we report a case of acute necrotizing retinal vasculitis as onset of SLE.

Twelve centres enrolled 436 eligible patients: 232 in Russia, 110 in Kazakhstan and 94 in Ukraine. Mean age ranged from 36 to 42 years and median SLE duration from 3 to 6.8 years. According to study definitions, 69.2% of patients in Russia, 72.7% in Kazakhstan and 55.4% in Ukraine had severe disease at diagnosis. SLE activity (Nasonova classification, 1972) decreased from diagnosis to the last visit in 2010 in all countries. At the last visit, mean (SD) Safety of Estrogens in Lupus Erythematosus National Assessment-Systemic Lupus Erythematosus Disease Activity Index score was 13.8 (10.5) in Russia, 19.4 (16.9) in Kazakhstan and 7.2 (6.8) in Ukraine, and Systemic Lupus International Collaborative Clinics/American College of Rheumatology damage index was 2.0 (2.2), 3.3 (3.2) and 2.2 (2.0), respectively. Treatment regimens included predominantly glucocorticoids (96.7-99.1%), immunosuppressants or cytotoxic drugs, for example, azathioprine and cyclophosphamide (20.7-53.2%), and antimalarial drugs (18.3-40.8%).

In rIFN-γ-primed RAW 264.7 macrophages, pretreatment with WAPP increased the productions of nitric oxide (NO) and tumor necrosis factor-α (TNF-α),and increased the expressions of inducible nitric oxide synthase (iNOS) at the protein level and of iNOS and TNF-α at the mRNA level. Molecular data revealed that WAPP upregulated the transcriptional activity and translocation of nuclear factor-κB (NF-κB) by activating inhibitory kappa B-α (IκB-α) degradation and phosphorylation. Furthermore, WAPP upregulated the phosphorylations of p38 MAP kinase, c-Jun NH2-terminal kinase (JNK), and extracellular signal-regulated kinase 1/2 (ERK1/2). In cycloheximide-induced immunosuppressed rats, pretreatment with WAPP (100, 200, or 400mg/kg, p.o.) increased the serum levels of albumin and globulin, and reduced immobility times.

We report a case of slowly progressive anti-Yo-associated paraneoplastic cerebellar degeneration (PCD) with breast cancer in a 54-year-old woman. The symptoms of limb and truncal ataxia, and dysarthria gradually progressed during the course of 1 year, and the modified Rankin scale (mRS) score was 2. A mastectomy with sentinel lymph node resection was performed for the breast cancer. No malignant cells were found on histopathological examination of the lymph node. Combination chemotherapy with adriamycin and cyclophosphamide (AC) prevented neurologic deterioration. However, subsequent treatment with trastuzumab and paclitaxel did not prevent progression of the symptoms (mRS score 3). Brain magnetic resonance imaging showed atrophy of the cerebellar hemispheres without brain stem atrophy. Anti-Yo antibody was detected in the serum, which led to a diagnosis of anti-Yo-associated PCD. We resected an enlarged axillary lymph node, which was found on computed tomography. The histopathological analysis of the lymph node revealed foreign body granuloma, which suggested an association with necrotic malignant tissue. Following additional tegafur-uracil therapy and two courses of intravenous immunoglobulin (IVIg), the cerebellar signs and symptoms gradually improved (mRS score 2). The clinical course shows that PCD can present as a slowly progressive cerebellar symptom. We propose an active treatment for anti-Yo-associated PCD consisting of tumor resection, combined chemotherapy, and IVIg.

Primary bone lymphoma and primary adrenal lymphoma are rare clinicopathological entities of non-Hodgkin's lymphoma (NHL). We present the first case of diffuse large B-cell lymphoma with the involvement of a single bone and both adrenal glands alone with adrenal insufficiency. As primary extranodal NHL may have other unusual extranodal lesions, which may present unexplained clinical findings, patients with primary extranodal NHL require careful systemic examination, even when lymphadenopathy is absent.
Neuropathy is a common and potentially disabling complication of adjuvant taxane therapy. Recent studies have identified candidate single nucleotide polymorphisms associated with taxane-induced neuropathy. Therefore, we sought to determine whether neuropathy was associated with breast cancer recurrence in a clinical trial population who received adjuvant taxane therapy.

The CXCR4 antagonist AMD3100 is progressively replacing cyclophosphamide (CYP) as adjuvant to granulocyte colony-stimulating factor (G-CSF) to mobilize hematopoietic stem cells (HSC) for autologous transplants in patients who failed prior mobilization with G-CSF alone. It has recently emerged that G-CSF mediates HSC mobilization and inhibits bone formation via specific bone marrow (BM) macrophages. We compared the effect of these three mobilizing agents on BM macrophages, bone formation, osteoblasts, HSC niches and HSC reconstitution potential. Both G-CSF and CYP suppressed niche-supportive macrophages and osteoblasts, and inhibited expression of endosteal cytokines resulting in major impairment of HSC reconstitution potential remaining in the mobilized BM. In sharp contrast, although AMD3100 was effective at mobilizing HSC, it did not suppress osteoblasts, endosteal cytokine expression or reconstitution potential of HSC remaining in the mobilized BM. In conclusion, although G-CSF, CYP and AMD3100 efficiently mobilize HSC into the blood, their effects on HSC niches and bone formation are distinct with both G-CSF and CYP targeting HSC niche function and bone formation, whereas AMD3100 directly targets HSC without altering niche function or bone formation.
A 22-year-old, wild-caught male kori bustard (Ardeotis kori) developed a large, slow-growing subcutaneous mass over the keel. The mass was surgically debulked and histopathologically described as a myxosarcoma. Surgical dehiscence and concurrent local tumor regrowth, with no evidence of metastasis, occurred over the subsequent 3 months, necessitating 2 additional surgical procedures to close the wound. At 19 weeks after the initial procedure, a second debulking surgical procedure was performed, at which time carboplatin-impregnated matrix beads were placed in the lesion. Moderate local tumor regrowth was clinically appreciable 4 weeks after surgery, at which time an oral metronomic chemotherapeutic protocol consisting of daily cyclophosphamide (10 mg/m(2)) and meloxicam (0.1 mg/kg) was initiated. Four months later, the tumor was no longer palpable. While oral therapy was discontinued during the breeding season, mass regrowth was observed, and the mass was surgically debulked before reinitiating oral chemotherapy. Treatment was extended for over 1 year with no hematologic evaluation or serum biochemical abnormalities, and the bird otherwise remained clinically healthy. To our knowledge, this is the first report of a myxosarcoma in a bustard species and the first report of successful clinical application of metronomic chemotherapy in an avian species.

Currently, there is no ideal noninvasive method to quantify the progressive loss of pancreatic β-cell mass (BCM) that occurs in type 1 diabetes. Magnetic resonance imaging has detected gross differences in BCM between healthy and diabetic mice using the contrast agent manganese, which labels functional β-cells and increases the water proton relaxation rate (R1), but its ability to measure gradations in BCM during disease progression is unknown. Our objective was to test the hypothesis that measurements of the manganese-enhanced pancreatic R1 could detect decreasing BCM in a mouse model of type 1 diabetes. We used cyclophosphamide-accelerated BDC2.5 T-cell receptor transgenic nonobese diabetic mice, which experience development of type 1 diabetes during a 7-day time period after cyclophosphamide injection, whereas transgene-negative mice do not. We measured the manganese-enhanced pancreatic R1 before cyclophosphamide injection (day 0) and on days 3, 4, 5, and 7 afterward. Pancreatic R1 remained constant in transgene-negative mice and decreased stepwise day-to-day in transgene-positive mice, mirroring their loss of BCM, confirmed by pancreatic insulin measurements and histology. Changes in R1 in transgene-positive mice occurred before elevations in blood glucose, a clinical indicator of diabetes, suggesting potential for early noninvasive detection of changes in functional BCM.

The essential oil showed a predominance of monoterpene compounds, being the terpinolene, p-cymene-8-ol, and p-cymene, present in the essential oil extracted in the 3 years. The essential oil showed a protection against cyclophosphamide-induced genotoxicity, and the cytotoxicity index polychromatic erythrocytes/normochromatic erythrocytes ratio in animals treated with oil at all doses (1.34 ± 0.33; 1.15 ± 0.1; 1.11 ± 0.13) did not differ from the negative control animal (1.31 ± 0.33), but from the cyclophosphamide group (0.61 ± 0.12). Cytotoxicity, at a concentration of 40.0 μg/mL, and antimicrobial activity were not observed for the essential oil (minimum inhibitory concentration ≥0.5 mg/mL). The essential oil did not change the levels of caspase-3 in the TNF-α level.
Allogeneic blood or bone marrow transplantation (BMT) is a potentially curative therapy for high-risk hematologic malignancies not curable by standard chemotherapy, but the procedure is limited by the availability of human leukocyte antigen-matched donors for many patients, as well as toxicities including graft-versus-host disease (GVHD). Our group has developed the use of high-dose post-transplantation cyclophosphamide (PTCy) to selectively remove alloreactive T cells without compromising engraftment. This protocol has allowed for successful transplantation of human leukocyte antigen (HLA)-haploidentical (haplo) grafts, thus expanding the donor pool for the many patients who would not otherwise be a candidate for this life-saving procedure. In this review we will summarize the data that led to the development of PTCy, then focus on the outcomes of haploBMT trials with PTCy across different transplant platforms for patients with malignant hematologic diseases, and finally we will discuss emerging evidence that suggests equivalency of haploBMT with PTCy compared with more traditional transplants.

Overall RR was 30.0% in the NIP and 38.5% in the EP group; there was no significant difference (P=0.236). The PFS in the EP group was little longer than that of NIP group, with 6.5 months for EP and 6.0 months for NIP group, but the difference was statistically non-significant (P=0.163). The median OS and one year survival rates were 10.4 months and 36.3% for NIP group, and 10.8 months and 49.0% for EP respectively, EP showing a survival benefit, although this was not statistically significant. Both groups well tolerated the adverse effects. The incidence of grade I-II leucopenia and alopecia in the NIP group was significantly higher than that of EP group (32.5% vs. 10.4% (P<0.001, 35.0% vs. 12.5%, P<0.001).

Pauci-immune glomerulonephritis often manifests with rapidly deteriorating kidney function, which may be accompanied by distinctive clinical features of systemic necrotizing small-vessel vasculitis of one the following clinical phenotypes: microscopic polyangiitis, granulomatosis with polyangiitis or eosinophilic granulomatosis with polyangiitis. These are associated with a wide spectrum of vasculitic manifestations in different organ systems at clinical presentation and during the course of the disease. ANCA specificity is associated with distinct clinical syndromes and different prognostic profiles among patients. The key element of the management of patients with pauci-immune glomerulonephritis, with or without systemic vasculitis, is the clinical acumen, which results in timely diagnosis. Speed in diagnosis is crucial for the quick institution of immunosuppressive therapy aimed at removing circulating autoantibodies and quelling the inflammatory process.
Five consecutive cases of anti-NMDA-receptor encephalitis that we encountered were marked by a rapidly fluctuating level of consciousness associated with psychotic and delirious mental states. Opisthotonus, catatonia, and rhythmic and non-rhythmic involuntary movements of the mouth and jaw were also characteristic features of these particular cases. Serious and potentially fatal problems included epilepsia partialis continua, partial and generalized seizures, and respiratory depression, resembling the symptoms of encephalitis lethargica. An epidemic of encephalitis lethargica, also known of Economo encephalitis, occurred around 1917. Magnetic resonance imaging revealed edema of the neocortex in two cases and electroencephalography showed polymorphic and monomorphic delta slowing in the acute stage, although electroencephalographic seizure activity were not apparent. Routine cerebrospinal fluid analyses revealed lymphocyte-dominant pleocytosis in three cases, but antibodies against the NMDA-GluR subunit, GluN2B N-terminal, were at a high level in the fluid. All patients recovered without apparent sequelae. Two patients found to have ovarian teratoma underwent surgery for tumor removal. Treatments included pulse intravenous methylprednisolone, high-dose immunoglobulin, and plasma exchange together with seizure control and respiratory support. However, rituximab and or cyclophosphamide pulse therapy should also be considered for intractable cases, as indicated by recent reports.
