Chronic low-grade inflammation plays a role in the pathogenesis of several chronic diseases including cancer. Physical activity (PA) and diet have been supposed to modulate inflammatory markers. We evaluated the effects of a 24-month dietary and/or PA intervention on plasma levels of pro-inflammatory cytokines, a secondary analysis in the DAMA factorial trial.

In the Bolivian Chaco, recent surveys documented a dramatic decrease in the prevalence of soil-transmitted helminth (STH) infections as compared with the 1980s after thirty years of preventive chemotherapy (PC). Concomitant immunological rearrangements are expected. Because nematode infections are associated with increased levels of circulating IgE and glycoprotein CD30 soluble form (sCD30), this study aims to evaluate changes in serological markers of T helper (Th)2-cells activity between 1987 (high STH prevalence) and 2013 (low STH prevalence) in rural communities in the Bolivian Chaco area.

Article Synopsis
  • High accuracy diagnostic tests are essential for diagnosing both active tuberculosis (TB) and latent Mycobacterium tuberculosis (MTB) infections, with a new assay called LIOFeron®TB/LTBI being tested against the established QuantiFERON®-TB Gold Plus test.
  • The study involved 389 subjects classified into different health categories, and blood samples were analyzed using both tests to compare their effectiveness in identifying active TB and latent infections.
  • Results showed that both tests had excellent agreement in detecting MTB infections, but the LIOFeron®TB/LTBI assay demonstrated better sensitivity in identifying latent infections compared to the QuantiFERON®-TB Gold Plus test.

Article Synopsis
  • * Researchers discovered that 20% of activated CD4 T-cell clones in these patients specifically recognize intrinsic factor, primarily exhibiting characteristics of T helper 17 and T helper 1 cells.
  • * Findings suggest that these T cells play a significant role in the disease's progression and indicate the T helper 17/T helper 1 pathway could be a potential target for new treatments.

Systemic lupus erythematosus is frequently associated with antiphospholipid syndrome. Patients with lupus-antiphospholipid syndrome are characterized by recurrent arterial/venous thrombosis, miscarriages, and persistent presence of autoantibodies against phospholipid-binding proteins, such as β2-Glycoprotein I. We investigated the cytokine production induced by β2-Glycoprotein I in activated T cells that infiltrate atherosclerotic lesions of lupus-antiphospholipid syndrome patients.

Nontuberculous mycobacteria are the most frequent cause of chronic cervical lymphadenitis in childhood. The aim of the study was to evaluate the performance of IL-2, IL-17, and INF-γ in-house enzyme-linked immunospot assays using a Mycobacterium avium lysate, in order to identify a noninvasive diagnostic method of nontuberculous mycobacteria infection. Children with subacute and chronic lymphadenopathies or with a previous diagnosis of nontuberculous mycobacteria lymphadenitis were prospectively enrolled in the study.
