A 51-year old woman was admitted with multiple cerebral, pulmonary and intra-abdominal abscesses. The combination of apparent immunosuppression, obesity, diabetes mellitus, hypertension, hypokalaemia, osteoporotic fractures and bilateral shoulder avascular necrosis led to a clinical diagnosis of Cushing's syndrome (CS). This was biochemically confirmed as follows: midnight serum cortisol 4275 nmol/L (60-250), non-suppressed overnight dexamethasone suppression test, raised salivary cortisol 716 nmol/L (5-46) and ACTH 639 ng/L (0-46)...

PURPOSE: We conducted a survey of providers to assess for practice patterns in diagnosing and treating new-onset refractory status epilepticus (NORSE). NORSE is the occurrence of prolonged seizures that are not responsive to initial therapies in otherwise healthy individuals without obvious cause on initial presentation. This entity is thought to have multiple etiologies, including autoimmune. METHOD: A 29-question electronic survey was sent to providers included in the Neurocritical Care Society emailing list...

Constitutive activation of signal transducer and activator of transcription 3 (STAT3) in tumor cells and tumor associated dendritic cells (DCs) plays a major role in the progression of cancer. JSI-124 (Cucurbitacin I) is a potent inhibitor of STAT3, however, its poor solubility and non-specificity limits its effectiveness in cancer immunotherapy. In order to achieve a nano-carrier for solubilisation and passive targeting of JSI-124 to tumor cells and tumor associated DCs, the drug was chemically conjugated to pendent COOH groups of self-associating poly(ethylene oxide)-block-poly(-carboxylate-ε-caprolactone) (PEO-b-PCCL)...

PURPOSE OF REVIEW: Despite modern immunosuppression, renal allograft rejection remains a major contributor to graft loss. Novel biomarkers may help improve posttransplant outcomes through the early detection and treatment of rejection. Our objective is to provide an overview of proteomics, review recent discovery-based rejection studies, and explore innovative approaches in biomarker development. RECENT FINDINGS: Urine MMP7 was identified as a biomarker of subclinical and clinical rejection using two-dimensional liquid chromatography tandem-mass spectrometry (LC-MS/MS) and improved the overall diagnostic discrimination of urine CXCL10 : Cr alone for renal allograft inflammation...

Expression of PD-L1, the ligand for T-cell inhibitory receptor PD-1, is one key immunosuppressive mechanism by which cancer avoids eradication by the immune system. Therapeutic use of blocking antibodies to PD-L1 or its receptor PD-1 has produced unparalleled, durable clinical responses, with highest likelihood of response seen in patients whose tumour or immune cells express PD-L1 before therapy. The significance of PD-L1 expression in each cell type has emerged as a central and controversial unknown in the clinical development of immunotherapeutics...

Although effects of Merocel(®) nasal packs and silicone splints on nasal flora alterations and bacteremia formation after septoplasty were assessed before, the effect of transseptal suturing technique has not been studied yet. The objective of this study is to compare nasal flora alterations and bacteremia occurrence rates between Merocel packs, silicone splints, and transseptal suturing technique in septoplasty. Ninety patients were divided into three groups randomly: Merocel packing (Group M), silicone splint (Group S), and transseptal suturing without packing (Group T)...

PURPOSE: The definitions of sepsis and septic shock have recently been revised in adults, but contemporary data are needed to inform similar approaches in children. METHODS: Multicenter cohort study including children <16 years admitted with sepsis or septic shock to ICUs in Australia and New Zealand in the period 2012-2015. We assessed septic shock criteria at ICU admission to define sepsis severity, using 30-day mortality as outcome. Through multivariable logistic regression, a pediatric sepsis score was derived using variables available within 60 min of ICU admission...

Transplantation of stem cells represents an upcoming therapy for many degenerative diseases. For clinical use, transplantation of pluripotent stem cell-derived cells should lead to integration of functional grafts without immune rejection or teratoma formation. Our previous studies showed that the risk of teratoma formation is highly influenced by the immune system of the recipients. In this study, we have observed a higher teratoma formation rate when undifferentiated so-called multipotent adult germline stem cells (maGSCs) were transplanted into the heart of T, B, and natural killer (NK) cell-deficient RAG2(-/-)γc(-/-) mice than in RAG2(-/-) mice, which still have NK cells...

Mycolactone is the exotoxin virulence factor produced by Mycobacterium ulcerans, the pathogen responsible for Buruli ulcer. The skin lesions and immunosuppression characteristic of this disease result from the action of mycolactone, which targets the Sec61 complex and inhibits the co-translational translocation of secretory proteins into the endoplasmic reticulum. In this study, we investigate the effect of mycolactone on the Sec61-dependent biogenesis of different classes of transmembrane protein (TMP). Our data suggest that the effect of mycolactone on TMP biogenesis depends on how the nascent chain initially engages the Sec61 complex...

Hepatitis B reactivation associated with immune suppressive and biological therapies is emerging to be an important cause of morbidity and mortality in patients with current or prior exposure to hepatitis B virus infection. The population at risk for HBV reactivation includes those who are either currently infected with HBV or have past exposure to HBV. Since curative and eradicative therapy for HBV is not currently available, there is a large reservoir of individuals at risk for HBV reactivation in the general population...

Common variable immunodeficiency is a primary immunodeficiency characterized by hypogammaglobulinemia and recurrent bacterial infections. We report a case of a 44-year-old male patient with end-stage renal disease and an established diagnosis of common variable immunodeficiency who underwent a living unrelated kidney transplant. He remained nearly infection free on maintenance immunoglobulin replacement. However, his posttransplant course was complicated by acute rejection that ultimately led to allograft loss...

Trichoblastoma is rare, benign skin neoplasm that may be difficult to distinguish from malignant baso-cellular skin cancer. Renal transplant recipients are at increased risk for development of skin malignancies. Resection and histopathological evaluation of a suspicious lesion is mandatory to determine malignant skin changes. We present the first reported case of trichoblastoma in a renal transplant recipient. Proper diagnosis enables less aggressive resection and maintenance of the same immunosuppressive protocol...

PURPOSE: Studies have shown that arecoline, the major alkaloid component of betel nuts, alters the activity of enzymes in the cytochrome P450 (CYP-450) family. Tacrolimus, an immunosuppressant that protects against organ rejection in transplant recipients, not only is mainly metabolized by CYP3A enzymes but also has a narrow therapeutic range. We aimed to investigate whether dose-adjusted blood trough levels of tacrolimus differed over time between betel nut-chewing and non-betel nut-chewing liver transplant recipients...

BACKGROUND: In kidney transplant recipients (KTRs) with hepatitis B virus (HBV) infection, immunosuppression may increase viral replication with increased risk for liver disease progression and HBV-related kidney diseases, factors that could adversely influence graft and patient outcomes. We aimed to analyze the impact of different phases of HBV infection on the outcomes in KTRs. METHODS: Using the Organ Procurement and Transplant Network/United Network for Organ Sharing database, we selected adult KTRs from 2001 to 2011 who received peri-operative antibody induction followed by calcineurin inhibitor/mycophenolate mofetil maintenance with/without steroid...

AIM: The aim of this study was to evaluate risk factors affecting graft and patient survival after transplantation from deceased donors. METHODS: We retrospectively analyzed the outcomes of 186 transplantations from deceased donors performed at our center between 2006 and 2014. The recipients were divided into two groups: Group I (141 recipients without graft loss) and Group II (45 recipients with graft loss). Kaplan-Meier, log-rank test, and Cox proportional hazard regressions were used...

An 8-year-old girl with Chediak-Higashi syndrome (CHS) had pulmonary complications after hematopoietic stem cell transplantation (HSCT) for hemophagocytic lymphohistiocytosis (HLH) and eventually underwent single living-donor lobar lung transplantation (LDLLT). Electron micrographic findings showed vagus nerve tissue in extracted lung having granular inclusions, which are pathognomonic for CHS. Because her mother was the donor for both hematopoietic stem cell and lung transplantations, she was weaned from immunosuppression and is doing well 3 years after lung transplantation...
