Objectives: The aim of this review was to summarize existing data on the contribution of Vitamin D level and/or deficiency/insufficiency to systemic sclerosis susceptibility and its clinical features.
Methods: An electronic literature search for eligible studies among all papers published prior to 30 June 2024 was conducted through PubMed, EMBASE, Web of science, and Scopus databases. Meta-analyses estimating pooled raw mean differences, odds ratios, and Pearson together with subgroup analyses and meta-regressions were performed for the association of Vitamin D with susceptibility to systemic sclerosis and disease presentation.
Background: Screening for latent tuberculosis infection using Interferon-Gamma Release Assays is a routine procedure prior to the initiation of anti-tumor necrosis factor (TNF) biotherapy or immunosuppressive therapy. However, indeterminate results are relatively frequent and are an obstacle to treatment initiation.
Aim: The aim of this cross-sectional study was to estimate the frequency of indeterminate QuantiFERON-TB Gold Plus test results in Tunisian patients, and to analyze the potential clinico-biological risk factors associated with these indeterminate results.
