A Case of Cutaneous Mycobacterium chelonae in Common Variable Immunodeficiency

Mycobacterium chelonae is a rare acid fast bacilli that grows rapidly when compared to other members of the Mycobacteria genus. Localized cutaneous infections (i.e. cellulitis/ abscess) are common in immunocompetent patients, but in an immune compromised host disseminated infections are more prevalent. Disseminated cutaneous manifestations most commonly present in patients who are immunosuppressed by malignancy, corticosteroid therapy, various immunomodulating drugs used in organ transplantation or secondary immunodeficiencies1.

Authors: Rombauts A, Abelenda-Alonso G, Cuervo G, Gudiol C, Carratalà J Abstract INTRODUCTION: Despite adequate antibiotic coverage, community-acquired pneumonia (CAP) remains a leading cause of hospitalization and mortality worldwide. It induces both a local pulmonary and a systemic inflammatory response, particularly significant in severe cases. The intensity of the dysregulated host response varies from patient to patient and has a negative impact on survival and other outcomes. AREAS COVERED: This comprehensive review summarizes the pathophysiological aspects of the inflammatory response in CAP, brie...

Boosting the sensitivity of in vitroβ-lactam allergy diagnostic tests. Chem Commun (Camb). 2020 Oct 14;56(80):11973-11976 Authors: Peña-Mendizabal E, Morais S, Maquieira Á Abstract The synthesis of structurally new haptens and the development of suitable antigens are essential for boosting the sensitivity of drug allergy diagnostic testing. Unprecedented structural antigens for benzylpenicillin and amoxicillin are characterised and evaluated in a cohort of 70 subjects with a turnkey solution based on consumer electronics.

This study was designed to 1) assess the efficacy of a second brain biopsy when the first biopsy was nondiagnostic, 2) identify possible factors associated with an increased diagnostic rate in the second biopsy, and 3) analyze additional morbidity induced by the second biopsy. METHODS: We performed a retrospective cohort study from 2009 to 2019, during which 1,919 patients underwent a brain biopsy, including 30 who were biopsied twice (1.6%). The specific histological diagnosis rate, diagnosis-associated factors, and complication rate were assessed for the 30 twice-biopsied patients. RESULTS: The second biopsy allo...

CONCLUSION: DAAs are effective and safe in the treatment of recurrent HCV infection in LT recipients with history of HCC. Relapse to pre- and post-LT DAA therapy is associated with post-transplantation HCC recurrence. PMID: 33033569 [PubMed]

The patient is a 17-year-old girl referred to our primary immunodeficiency consult service after the diagnosis of a complicated left deltoid abscess due to Salmonella Typhimurium. Three months earlier she had noticed a stiff lesion in the left upper arm similar to an insect sting, which was diagnosed as cellulitis and treated with oral flucloxacillin for 8 days. Two weeks later she presented with fever and a local abscess. The abscess was drained and treated with oral amoxicillin-clavulanic acid.

AbstractPurpose of ReviewThe goal of this paper is to review the major adverse cutaneous reactions that have been reported to the most commonly used biologics.Recent FindingsAnti-TNF agents and immune checkpoint inhibitors have significant, immune-mediated cutaneous manifestations that can necessitate discontinuation. Anti-TNF agents, IL-6 inhibitors, and IL-12/23 inhibitors can paradoxically cause psoriasis flares or unmask previously undiagnosed psoriasis. IL-17 inhibitors are unique in increasing risk forCandida infections. Benign injection site reactions, non-specific rash, cellulitis, and hypersensitivity reactions ar...
