Posaconazole is an antifungal drug used in both prophylaxis and treatment of invasive fungal infections. Its oral formulation requires therapeutic drug monitoring. To overcome gastric acidity, a gastro-resistant posaconazole tablet has recently been developed. POSANANTES was a prospective non interventional study that aimed to monitor plasma concentration trough level (Cmin) of posaconazole tablets used prophylactically in patients with hematological malignancies. Fifty patients were included. Group A (n= 31) included patients receiving induction chemotherapy for myeloid malignancies and group B (n=19) included patients treated for graft versus host disease after allogeneic hematopoietic stem cells transplantation...

Allogeneic hematopoietic cell transplantation offers the best chance for cure in many hematologic malignancies. Key decisions include patient selection, donor and graft source, conditioning regimen, and graft-versus-host disease (GVHD) prophylaxis. Transplant is risky; only one-third survive long term. Complications include relapse, GVHD, infection, and end-organ dysfunction. Expanding indications for transplantation, advancing upper age limits, and improvements in patient care have resulted in increasing numbers of transplant survivors...

Allogeneic hematopoietic stem cell transplantation (HSCT) is a critically important therapy for hematological malignancies, inborn errors of metabolism, and immunodeficiency disorders, yet complications such as graft-vs.-host disease (GvHD) limit survival. Development of anti-GvHD therapies that do not adversely affect susceptibility to infection or graft-vs.-tumor immunity are hampered by the lack of a physiologically relevant, preclinical model of allogeneic HSCT. Here we show a spectrum of diverse clinical HSCT outcomes including primary and secondary graft failure, lethal GvHD, and stable, disease-free full donor engraftment using reduced intensity conditioning and mobilized peripheral blood HSCT in unrelated, fully MHC-matched Mauritian-origin cynomolgus macaques...

BACKGROUND: In a previously published study, the authors randomized 108 adult patients with a malignant hematologic disorder undergoing allogeneic bone marrow transplantation from a human leukocyte antigen-identical sibling to receive methylprednisolone (53 patients; MP+) or not to receive methylprednisolone (55 patients; MP-) as a part of graft-versus-host disease (GVHD) prophylaxis. All patients received cyclosporine and methotrexate. The cumulative incidence of acute GVHD was found to be significantly lower among the patients given MP...

The introduction of high-efficacy therapies for relapsing-remitting multiple sclerosis has driven re-evaluation of treatment goals and benefit:risk considerations in treatment choice. In the alemtuzumab Phase II and III clinical trials, patients treated with alemtuzumab 12 mg versus subcutaneous interferon beta-1a demonstrated significantly reduced annualized relapse rates and improved magnetic resonance imaging outcomes, and were significantly more likely to achieve no evidence of disease activity and reduction in brain volume loss...

OBJECTIVES: Chronic subdural hematoma is a commonly encountered disease in neurosurgic practice, whereas its increasing prevalence is compatible with the ageing population. Recommendations concerning postoperative thrombosis prophylaxis after burr-hole drainage of chronic subdural hematoma are lacking. The aim of this study was to analyze the correlation between recurrence of chronic subdural hematoma and postoperative application of thrombosis prophylaxis. DESIGN: Retrospective, consecutive sample of patients undergoing burr-hole drainage for chronic subdural hematoma over 3 years...

REVIEW
Amy Houghtelin, Catherine M Bollard
While progress has been made in the treatment of both hematologic cancers and solid tumors, chemorefractory or relapsed disease often portends a dismal prognosis, and salvage chemotherapy or radiation expose patients to intolerable toxicities and may not be effective. Hematopoietic stem cell transplant offers the promise of cure for many patients, and while mismatched, unrelated or haploidentical donors are increasingly available, the recipients are at higher risk of severe immunosuppression and immune dysregulation due to graft versus host disease...

BACKGROUND: Acute graft-versus-host disease (aGVHD) is an important complication of allogeneic stem cell transplantation (alloSCT). High dose glucocorticosteroids, are currently recommended as first-line treatment for grade II-IV aGVHD resulting in overall complete responses (CR) in 40%-50% of patients. No standard second-line regimen has been established. Different options have been reported, including anti-TNFα antibodies. METHODS: We retrospectively reviewed the outcome of 15 patients with steroid-refractory (SR) aGVHD treated with etanercept at our institution...

Compared with standard graft-versus-host disease (GVHD) prophylaxis platforms, post-transplantation cyclophosphamide (PTCy) after T cell-replete HLA-haploidentical (haplo) bone marrow transplantation (BMT) reduces the risk of grades III to IV acute (a) and chronic (c) GVHD but maintains similar rates of grade II aGVHD. Given that mild GVHD has been associated with reduced treatment failure in HLA-matched BMT, we evaluated the risk factors for and effects of GVHD on survival in 340 adults with hematologic malignancies who engrafted after nonmyeloablative haplo-BMT with PTCy, mycophenolate mofetil, and tacrolimus...

The Japan Marrow Donor Program (JMDP) has facilitated unrelated peripheral blood stem cell transplantation (URPBSCT) since 2010. We conducted a prospective multicenter observational study to evaluate the feasibility of such transplantation. Between 2011 and 2014, 51 patients underwent URPBSCT from 8/8 allele-matched donors for hematological malignancies. The median age of the patients was 50 years; 21 had high-risk disease. Myeloablative conditioning regimens were used in 31 patients, and tacrolimus based graft-versus-host disease (GVHD) prophylaxis was used for all patients...

BACKGROUND: The impact of protein intake level leads to considerable alterations of the host essential amino acid profiles in the context of chronic viral infectious process. Amino acids play an important role in the pathogenesis of virus-related infections both as basic substrates for constant protein synthesis and as regulators in many metabolic pathways. The excess or deficiency of these host essential nutritional elements can play a limiting role in the life cycle of some viruses...

BACKGROUND: Given the potential of cotrimoxazole preventive therapy (CPT) to prevent bacterial and malarial infections in HIV-exposed, uninfected (HEU) infants, it is important to evaluate the effects of its concurrent use with antiretroviral agents that have overlapping toxicity profiles. METHODS: We used data from the Breastfeeding, Antiretrovirals, and Nutrition study (2004-2010) to evaluate the association of CPT and antiretrovirals with hematologic measures (hemoglobin, neutrophil, and alanine aminotransferase levels) from 6 to 48 weeks of age in 2006 HEU infants in Lilongwe, Malawi...
