Distinct T-cell immunophenotypic signature in a subset of sarcoidosis patients with arthritis

Background: The objective of the study was to assess T-cell subsets in sarcoidosis patients with or without articular involvement.

Methods: Treatment-naïve patients were divided into Group A (articular) and Group B (non-articular) based on joint involvement. Flow cytometric analysis of T-cell subsets and pro-inflammatory cytokines were carried out in the peripheral blood.

Hypercalcaemia secondary to disseminated Mycobacterium abscessus and Mycobacterium fortuitum

The incidence and prevalence of nontuberculous mycobacteria (NTM) infection is on the rise with many cases still going unreported. Given the vague and nonspecific clinical features of NTM infections, it is often missed or mistaken for Mycobacterium tuberculosis. The presumption that NTM infections are benign and do not contribute to morbidity no longer holds true.
