Some individuals, even when heavily exposed to an infectious tuberculosis patient, do not develop a specific T-cell response as measured by interferon-gamma release assay (IGRA). This could be explained by an IFN-γ-independent adaptive immune response, or an effective innate host response clearing Mycobacterium tuberculosis (Mtb) without adaptive immunity. In heavily exposed Indonesian tuberculosis household contacts (n = 1347), a persistently IGRA negative status was associated with presence of a BCG scar, and - especially among those with a BCG scar - with altered innate immune cells dynamics, higher heterologous (Escherichia coli-induced) proinflammatory cytokine production, and higher inflammatory proteins in the IGRA mitogen tube.

The pathogenesis of SLE is not fully understood; however, there are alterations in neutrophils and lymphocytes. Recent parameters assessing both neutrophil activations (Neut-RI, Neut-GI, IG) and activated lymphocytes (Re-Lymp, As-Lymp) can be used to assess the activation of immune cells.

In Indonesia, the second largest contributor of TB cases globally, private practitioners (PPs) often do not adhere to national TB guidelines. A district public-private mix programme to mitigate this issue was started in 2019, yet engagement remains low.

Purpose: We aim to analyze the proportion and level of coronavirus disease 2019 (COVID-19) seropositivity in patients with systemic lupus erythematosus (SLE) and explore factors associated with lower anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike receptor-binding domain (S-RBD) antibody levels.
Materials And Methods: A cross-sectional study involving patients with SLE was conducted. We included those aged 18-60 years, either unvaccinated or had received inactivated vaccine (CoronaVac; Sinovac Biotech Ltd.
