A 46-year-old man with myeloproliferative disorder received a stem cell transplant from an HLA-identical unrelated donor. Eight months status post transplantation, during the course of tacrolimus therapy, the patient developed severe epigastric pain and fever. FGS findings showed eruptions with blisters in the esophagus and ulcers in the stomach. Biopsy specimens revealed acidophilic inclusion bodies in the nuclei. Varicella zoster virus (VZV) DNA copies were detected in the serum. No skin lesions were observed prior to hospital admission. The diagnosis of visceral VZV infection was made and the gastric and esophageal lesions were successfully healed with acyclovir (ACV). Severe abdominal pain is one of the most important signs of VZV infection for recipients of stem cell transplantation.

Introduction Congenital malformations are a major cause of perinatal morbidity and mortality in developing countries and are assuming greater importance than ever before. They affect a variety of organ systems and various etiologies have been identified in literature including Toxoplasmosis, Other (syphilis, varicella-zoster, parvovirus B19), Rubella, Cytomegalovirus, Herpes Simplex (TORCH) infections, exposure to pollutants, consumption of tobacco and alcohol, and advanced maternal age. In developing countries, diagnosis is frequently delayed which leads to poorer outcomes.

Varicella-zoster virus (VZV) is a known cause of meningoencephalitis, typically in immunocompromised inpatients. We report a case of meningitis caused by VZV in an immunocompetent man in his 20s. Diagnosis was delayed due to the atypical presentation of painless occipital zoster mimicking atopic dermatitis, and the presence of hypoglycorrhachia in his cerebrospinal fluid.

The determinants of varicella-zoster virus (VZV)-associated central nervous system (CNS) infection have not been fully elucidated. This study aimed to investigate the incidence and risk factors, including immunosuppression, for different manifestations of VZV-associated CNS infection. Patient registers were used to include adults diagnosed with VZV-associated CNS infections between 2010 and 2019 in Sweden.

Background: Previous investigations into the causal relationship between infections and systemic lupus erythematosus (SLE) have yielded controversial results. This study delves into the bidirectional causal relationships between various infectious agents and SLE, employing two-sample Mendelian randomization (MR) from an immunological perspective.
Methods: Utilizing genome-wide association study (GWAS) data for 46 antibody-mediated immune responses (AMIRs) to 13 pathogens and three distinct SLE datasets, we employed Bayesian Weighted MR (BWMR) and inverse variance weighted (IVW) methods to ascertain causal links, supplemented by meta-analysis to resolve inconsistencies.
