Histoplasmosis Related to Immunosuppression in a Patient with Crohn's Disease: A Diagnostic Challenge.

BACKGROUND Infliximab, a monoclonal antibody against tumor necrosis factor (TNF) alpha with proven efficacy and known safety profile, is currently widely used in the treatment of inflammatory bowel diseases. Increased risk for serious infections and malignant neoplasms secondary to immunosuppression is a major concern during therapy with this medication. Histoplasmosis is a granulomatous disease caused by the fungus Histoplasma capsulatum.

Update on the management and treatment of viral hepatitis.

This review aims to summarize the current evidence on the treatment of viral hepatitis, focusing on its clinical management. Also, future treatment options and areas of potential research interest are detailed. PubMed and Scopus databases were searched for primary studies published within the last ten years.

HLA-E gene polymorphisms in chronic hepatitis C: Impact on HLA-E liver expression and disease severity.

Hepatitis C virus usually produces chronic infection and liver damage. Considering that: i) the human leukocyte antigen-E (HLA-E) molecule may modulate the immune response, and ii) little is known about the role of HLA-E gene variability on chronic hepatitis C, we studied the impact of HLA-E polymorphisms on the magnitude of HLA-E liver expression and severity of hepatitis C. HLA-E variability was evaluated in terms of: i) single nucleotide polymorphism (SNP) alleles and genotypes along the gene (beginning of the promoter region, coding region and 3'UTR), and ii) ensemble of SNPs that defines the coding region alleles, considered individually or as genotypes.

A Day-4 Lille Model Predicts Response to Corticosteroids and Mortality in Severe Alcoholic Hepatitis.

Objectives: Prednisolone therapy increases the risk of infections in patients with severe alcoholic hepatitis (SAH). We evaluated whether the use of the Lille Model at day 4 (LM4) is useful to predict response to prednisolone compared with the classic day 7 (LM7) in order to limit a futile exposure to corticosteroids.

Methods: We performed a retrospective analysis of a large multinational cohort of patients with SAH with Maddrey's discriminant function (DF) ≥32.

Fatal disseminated strongyloidiasis after kidney transplantation.

Disseminated strongyloidiasis (DS) is a rare and severe parasitic disease that is difficult to recognize and affects immunocompromised individuals. We report the case of a kidney transplant recipient who presented with DS despite prophylaxis with albendazole. We have discussed the need for better prophylactic strategies and for a higher degree of suspicion in order to diagnose DS.
