This is a case series study to evaluate immunological markers associated with schistosomiasis advanced fibrosis, including 69 patients from an endemic area from the State of Sergipe and from the Hepatology Service of the University Hospital in Sergipe, Brazil. Hepatic fibrosis was classified based on Niamey protocol for ultrasonography (US). Immune response to Schistosoma mansoni antigens was evaluated by stimulating peripheral blood mononuclear cells (PBMCs) from these patients with either adult worm (SWAP—10 μg/ml) or egg (SEA—10 μg/ml) antigens or purified protein derivative of turberculin (PPD—10 μg/ml) or phytohemagglutinin (PHA—1 μg/ml) for 72 h. The levels of IFN-γ, TNF-α, IL-5, IL-10, and IL-17 were measured in these supernatants by ELISA and IL-9 by Luminex. Single nucleotide polymorphisms in IL-17, IL10, and CD209 genes were genotyped using TaqMan probe by qPCR. Higher levels of IL-9, IL-10, and IL-17 were found in PBMC supernatants of patients with advanced hepatic fibrosis. Direct correlations were detected between IL-9 and IL-17 levels with US spleen sizes, portal vein diameters, and periportal thickening. The CD209 rs2287886 AG polymorphism patients produce higher IL-17 levels. Together, these data suggest a role of these cytokines in the immunopathogenesis of advanced fibrosis in human schistosomiasis.

ABSTRACT The objective of this study was to evaluate the role of cytokines in hepatic fibrosis in the prehepatosplenic and early hepatosplenic stages of schistosomiasis mansoni. Hepatic fibrosis was classified by ultrasonography of 94 patients. Immunological evaluation was performed by the measurement of secreted cytokines (interleukin-5 [IL-5], IL-10, IL-13, gamma interferon, tumor necrosis factor alpha, and transforming growth factor β) in peripheral blood mononuclear cells (PBMC) stimulated by Schistosoma mansoni antigens. Significantly, higher levels of IL-5, IL-10, and IL-13 were found in supernatants of soluble egg antigen-stimulated PBMC from subjects with degree III hepatic fibrosis compared to patients with degree I or II fibrosis. Significant increases in IL-5 and IL-13 levels were also observed in some of the subjects who remained untreated for 1 year following initial assessment and developed more serious fibrosis during this period. The data suggest a role for type 2 cytokines in hepatic fibrosis in human schistosomiasis mansoni.

Background: Concern is growing about the negative consequences that response measures to the COVID-19 epidemic may have on the management of other medical conditions. Methods: A retrospective descriptive case-series study conducted at a large University-hospital in northern Italy, an area severely hit by the epidemic. Results: Between 23 February and 14 May 2020, 4160 (52%) COVID-19 and 3778 (48%) non-COVID-19 patients were hospitalized. COVID-19 admissions peaked in the second half of March, a period characterized by an extremely high mortality rate (27.4%). The number of admissions in 2020 was similar to 2019, but COVID-19 patients gradually occupied all available beds. Comparison between COVID-19 and non-COVID-19 admissions in 2020 revealed significant differences concerning all age classes and gender. Specifically, COVID-19 patients were older, predominantly male, and exhibited more comorbidities. Overall, admissions for non-communicable diseases (NCDs) in 2020 vs. 2019 dropped by approximately one third. Statistically significant reductions were observed for acute myocardial infarction (−78, −33.9%), cerebrovascular disease (−235, −41.5%), and cancer (−368, −31.9%). While the first two appeared equally distributed between COVID-19 and non-COVID-19 patients, chronic NCDs were statistically significantly more frequent in the former, except cancer, which was less frequent in COVID-19 patients. Conclusions: Prevention of collateral damage to patients with other diseases should be an integral part of epidemic response plans. Prospective cohort studies are needed to understand the long-term impact.

PURPOSE: Triple therapy for HCV-1 infection consists in boceprevir or telaprevir, ribavirin and PEG-interferon. Telaprevir is a P-glycoprotein substrate and it is metabolized by CYP3A4/5. No data have been published on intracellular penetration of telaprevir. We determined peripheral blood mononuclear cells (PBMCs) and trough plasma S and R telaprevir isomers concentrations; moreover, we evaluated the influence of some single nucleotide polymorphisms (SNPs) on these pharmacokinetic data after 1 month of triple therapy in humans. METHODS: Plasma and intracellular telaprevir concentrations were determined at the end of dosing interval (Ctrough) using ULPC-MS/MS validated methods; allelic discrimination was performed through real-time PCR. RESULTS: Median telaprevir Ctrough plasma concentrations were 2579 ng/mL and 2233 ng/mL for the pharmacologically more active S, and R, enantiomers, respectively, with median S/R plasma ratio of 1.11. In PBMC, the medians were 6863 ng/mL and 1096 ng/mL for S and R, respectively, with median S/R being 5.73. The PBMC:plasma ratio for S was 2.59 for R. Plasma ribavirin concentrations were directly correlated with plasma S-telaprevir concentrations. In linear regression analysis, only CYP24A1_rs2585428 SNP (p=0.003) and body mass index (p=0.038) were able to predict S-telaprevir PBMC concentrations. CONCLUSIONS: Our preliminary data could increase the understanding of mechanisms underlying telaprevir intracellular and plasma exposure, suggesting the implementation of pharmacogenetics in these drug kinetic studies. This article is open to POST-PUBLICATION REVIEW.

AimsTo explore the role of the suppressor of cytokine signalling 3 (SOCS3) gene in Graves’ ophthalmopathy (GO) patients.MethodsA case–control study was conducted in a Chinese Han population by recruiting 114 Graves’ disease (GD) patients with GO and 156 GD patients without GO. We determined SOCS3 mRNA and protein levels in Epstein–Barr virus-transformed lymphoblastoid cell lines (EBV-LCLs) from peripheral blood mononuclear cells (PBMCs) by quantitative real-time (QRT)-PCR analysis and western blot analysis. We also genotyped five single nucleotide polymorphisms (SNPs) in the SOCS3 locus (SOCS3 rs12952093, rs4969170, rs4969168, rs4969169 and rs2280148) in all 270 GD patients using ligase detection reaction and multiplex PCR analyses. QRT-PCR and western blot assays were then performed to compare SOCS3 mRNA and protein levels between the rs4969170 AA and GG genotype groups from 20 GO patients.ResultsBasal SOCS3 mRNA and protein expression levels were significantly increased in patients with GO (p<0.05). The SOCS3 rs4969170 AA genotype was strongly associated with GO (OR=3.5, 95% CI 1.6 to 7.5, p=0.001). The AA genotype carriers had significantly higher SOCS3 mRNA and protein levels than those with the GG genotype (p<0.05).ConclusionsPatients with GD who carry the AA genotype of the rs4969170 SNP in SOCS3 are more susceptible to the development of GO.

ABSTRACT Background: Trauma is one of the common surgical emergencies presenting at B. P. Koirala Institute of Health Sciences (BPKIHS), Nepal, a tertiary referral center catering to the needs of the population of Eastern Nepal and nearby districts of India. Objective: The objective of this study is to analyze the magnitude, epidemiological, clinical profile and outcome of trauma at B P Koirala Institute of Health Sciences. Materials and Methods: This descriptive case series study includes all patients with history of trauma coming to BPKIHS emergency and referred to the surgery department. We noted the detailed clinical history and examination, demographics, mechanism of injury, nature of injury, time of reporting in emergency, treatment offered (operative or non operative management) and analyzed details of operative procedure (i.e. laparotomy, thoracotomy, craniotomy etc.), average length of hospital stay, morbidity and outcome (according to Glasgow outcome scale). Collected data were analyzed using EpiInfo 2000 statistical software. Results: There were 1848 patients eligible to be included in the study. The mean age of the patients was 28.9 ± 19.3 years. Majority of the patients (38%) belonged to the age group of 21 - 40 years and the male to female ratio was 2.7:1. Most of the trauma victims were students (30%) followed by laborers (27%) and farmers (22%) respectively. The commonest causes of injury were fall from height (39%), road traffic accident (38%) and physical assault (18%); 78% of the patients were managed conservatively and 22% underwent operative management. Postoperative complications were seen in 18%. Wound infection 7.5%, neurological deficit including cerebrospinal fluid (CSF) otrorrhea was seen in 2.2% patients. Good recovery was seen in 84%, moderate disability in 5.2% patients and severe disability in 1.4% patients. The mortally was 6.3% and most of the deaths were related to traumatic brain injuries. Conclusions: In Nepal, trauma-related injury contributes significantly to morbidity and mortality and is the third leading cause of death. There are very few studies on trauma from this country and hence this study will help in understanding the etiology and outcome particularly in the Eastern region of Nepal.

Dysregulation of signaling pathways in multiple sclerosis (MS) can be analyzed by phosphoproteomics in peripheral blood mononuclear cells (PBMCs). We performed in vitro kinetic assays on PBMCs in 195 MS patients and 60 matched controls and quantified the phosphorylation of 17 kinases using xMAP assays. Phosphoprotein levels were tested for association with genetic susceptibility by typing 112 single-nucleotide polymorphisms (SNPs) associated with MS susceptibility. We found increased phosphorylation of MP2K1 in MS patients relative to the controls. Moreover, we identified one SNP located in the PHDGH gene and another on IRF8 gene that were associated with MP2K1 phosphorylation levels, providing a first clue on how this MS risk gene may act. The analyses in patients treated with disease-modifying drugs identified the phosphorylation of each receptor’s downstream kinases. Finally, using flow cytometry, we detected in MS patients increased STAT1, STAT3, TF65, and HSPB1 phosphorylation in CD19+ cells. These findings indicate the activation of cell survival and proliferation (MAPK), and proinflammatory (STAT) pathways in the immune cells of MS patients, primarily in B cells. The changes in the activation of these kinases suggest that these pathways may represent therapeutic targets for modulation by kinase inhibitors.
