Abstract
BACKGROUND The pseudo germ-free (PGF) model has been widely used to research the role of intestinal microbiota in drug metabolism and efficacy, while the modelling methods and the utilization of the PGF model are still not standardized and unified. A comprehensive and systematic research of the PGF model on the composition and function of the intestinal microbiota, changes in host cytochrome P450 (CYP450) enzymes expression and intestinal mucosal permeability in four different modelling cycles of the PGF groups are provided in this paper. RESULTS 16S rRNA gene amplicon sequencing was employed to compare and analyze the alpha and beta diversity, taxonomic composition, taxonomic indicators and predicted function of gut microbiota in the control and PGF groups. Bacterial richness and diversity decreased significantly in the PGF group beginning after the first week of establishment of the PGF model with antibiotic exposure. The PGF group exposed to antibiotics for 4-week-modelling possessed the fewest indicator genera. Moreover, increased intestinal mucosal permeability occurred in the second week of PGF model establishment, indicating that one week of antibiotic exposure is an appropriate time to establish the PGF model. The results of immunoblots revealed that CYP1A2, CYP2C19 and CYP2E1 expression was significantly upregulated in the PGF group compared with the control group, implying that the metabolic clearance of related drugs would change accordingly. The abundance of functional pathways predicted in the gut microbiota changed dramatically between the control and PGF groups. CONCLUSIONS This study provides information concerning the microbial and CYP450 enzyme expression profiles as a reference for evaluating drug metabolism differences co-affected by gut microbiota and host CYP450 enzymes in the PGF model.

Abstract
Serum sickness (SS) is a known phenomenon; however, it is commonly missed due to vague symptoms, and is usually confounded by other aetiologies that present similarly. Obinutuzumab is a novel anti-CD20 antibody agent that has been approved for chronic lymphocytic leukaemia (CLL) treatment. At the time of approval, it was not linked to SS; however, this phenomenon has been recognised with other anti-CD20 agents like rituximab. SS remains a rare entity, but it is important to be recognised accurately and quickly in the appropriate circumstances, so that effective treatment with corticosteroids can be initiated to alleviate inflammatory symptoms. Here we present a patient with CLL who developed maculopapular rash, fever and polyarthritis and elevated inflammatory markers consistent with serum sickness triggered by obinutuzumab and was effectively treated with corticosteroids.

Abstract
INTRODUCTION AND OBJECTIVES Considering that no studies have been done on a comprehensive review of Serum sickness-like reactions patients (SSLRs) at a referral center in Iran so far, this study aimed to determine the clinical and laboratory characteristics of children with SSRL in Tehran Children's Medical Center. PATIENTS The present study was a registry-based study in which the data of 94 SSLRs patients registered in a two-year period were investigated. Confirmation of fever, rash, urticaria, arthralgia / arthritis and history of antibiotic consumption up to three weeks before were the criteria for the diagnosis. RESULTS Fifty-one (54 %) patients were male with mean age of 56 ± 30 months and there was no significant difference in the age of the two genders. The mean onset of symptoms before hospitalization were 3.8 ± 2.7 days (1-14 days); this mean was significantly higher in males than in females (4.6 ± 2.9 versus 2.9 ± 1.7 days, P-value = 0.003). Among antibiotics, Co-amoxiclav and Cefixime antibiotics had the most frequency by 31 % and 33 %, respectively as the most important incidence factor of SSLRs. The mean duration of consumption of culprit medications in the incidence of SSLRs was 5.6 ± 2.9 days with a range of 1-15 days. CONCLUSIONS This study showed that among the antibiotics, Co-amoxiclav and Cefixime are more prevalent and a review of prescribing these two antibiotics for the treatment of the children's infections is essential if this finding is confirmed by other Iranian scholars.

Abstract
Most immune-mediated adverse drug reactions (IM-ADRs) involve the skin, and many have additional systemic features. Severe cutaneous adverse drug reactions (SCARs) are an uncommon, potentially life-threatening, and challenging subgroup of IM-ADRs with diverse clinical phenotypes, mechanisms, and offending drugs. T-cell-mediated immunopathology is central to these severe delayed reactions, but effector cells and cytokines differ by clinical phenotype. Strong HLA-gene associations have been elucidated for specific drug-SCAR IM-ADRs such as Stevens-Johnson syndrome/toxic epidermal necrolysis, although the mechanisms by which carriage of a specific HLA allele is necessary but not sufficient for the development of many IM-ADRs is still being defined. SCAR management is complicated by substantial short- and long-term morbidity/mortality and the potential need to treat ongoing comorbid disease with related medications. Multidisciplinary specialist teams at experienced units should care for patients. In the setting of SCAR, patient outcomes as well as preventive, diagnostic, treatment, and management approaches are often not generalizable, but rather context specific, driven by population HLA-genetics, the pharmacology and genetic risk factors of the implicated drug, severity of underlying comorbid disease necessitating ongoing treatments, and cost considerations. In this review, we update the basic and clinical science of SCAR diagnosis and management.

Abstract
Cutaneous adverse drug reactions (ADRs) are among the most frequent adverse reactions in patients receiving drug therapy. They have a broad spectrum of clinical manifestations, are caused by various drugs, and result from different pathophysiological mechanisms. Hence, their diagnosis and management is challenging. Severe cutaneous ADRs comprise a group of diseases with major morbidity and mortality, reaching 30 % mortality rate in cases of Toxic Epidermal Necrolysis. This chapter covers the terminology, epidemiology, pathogenesis and classification of cutaneous ADR, describes the severe cutaneous ADRs and the clinical and laboratory approach to the patient with cutaneous ADR and presents the translation of laboratory-based discoveries on the genetic predisposition and pathogenesis of cutaneous ADRs to clinical management guidelines.

Mode of renal replacement therapy determines endotoxemia and neutrophil dysfunction in chronic kidney disease. Sci Rep 2016; 6:34534.

Abstract
Bacterial infection and sepsis are common complications of chronic kidney disease (CKD). A vicious cycle of increased gut permeability, endotoxemia, inadequate activation of the innate immune system and resulting innate immune dysfunction is hypothesized. We assessed endotoxemia, neutrophil function and its relation to oxidative stress, inflammation and gut permeability in patients with CKD grade 3–5 without renal replacement therapy (CKD group, n = 57), patients with CKD stage 5 undergoing haemodialysis (HD, n = 32) or peritoneal dialysis (PD, n = 28) and patients after kidney transplantation (KT, n = 67) in a cross-sectional observational study. In HD patients, endotoxin serum levels were elevated and neutrophil phagocytic capacity was decreased compared to all other groups. Patients on HD had a significantly higher mortality, due to infections during follow up, compared to PD (p = 0.022). Oxidative stress, neutrophil energy charge, systemic inflammation and gut permeability could not completely explain these differences. Our findings suggest that dialysis modality and not renal function per se determine the development of neutrophil dysfunction and endotoxemia in CKD-patients. HD patients are particularly prone to neutrophil dysfunction and endotoxemia whereas neutrophil function seems to improve after KT. Multi-target approaches are therefore warranted to improve neutrophil function and potentially reduce the rate of infections with patients undergoing haemodialysis.

Abstract
Background Acute gastrointestinal injury (AGI) is a common problem in the intensive care unit (ICU). This study is a review of the gastrointestinal function of patients in critical care, with the aim to assess the feasibility and effectiveness of grading criteria developed by the European Society of Intensive Care Medicine (ESICM) Working Group on Abdominal Problems (WGAP). Methods Data of patients who were admitted to the ICU of Shenzhen People’s Hospital, Shenzhen, People’s Republic of China, from January 2010 to December 2011 were reviewed. A total of 874 patients were included into the current study. Their sex, age, ICU admissive causes, complication of diabetes, AGI grade, primary or secondary AGI, mechanical ventilation (MV), and length of ICU stay (days) were recorded as risk factors of death. These risk factors were studied by unconditioned logistic regression analysis. Results All the risk factors affected mortality rate. Unconditional logistic regression analysis revealed that the mortality rate of secondary AGI was 71 times higher than primary AGI (odds ratio [OR] 4.335, 95% CI [1.652, 11.375]). When the age increased by one year, the mortality probability would increase fourfold. Mortality in patients with MV was 63-fold higher than for patients with non-MV. Mortality rate increased 0.978 times with each additional day of ICU stay. Conclusion Secondary AGI caused by severe systemic conditions can result in worsened clinical outcomes. The 2012 ESICM WGAP AGI recommendations were to some extent feasible and effective in guiding clinical practices, but the grading system lacked the support of objective laboratory outcomes.
