HIV infection is characterized by progressive immunodeficiency leading to invasion by opportunistic pathogens. It was of interest to find out if disease course in HIV type-1 infection could have any relation with alteration in body iron status among individuals with history of oral iron intake. A follow-up study of immunologic and virologic markers in relation to disease progression was undertaken on asymptomatic HIV-1 positive blood donors with history of oral iron intake (subgroup I) compared to those without such history (subgroup II). High serum iron was associated with elevated levels of Th2 category of cytokines, heightened immune activation, faster decline in CD4 + T lymphocyte count and higher viral set point. Pulmonary tuberculosis (PT) was the most common AIDS related illness (ARI) (>70%) recorded among subgroup I compared to non-PT category of ARI. Median ARI free duration (months) was shorter among those who developed PT compared to those developing non-PT category of ARI i.e. 30 (95% CI as 26,32) versus 67(95% CI as 60,71) in subgroup I and 47 (95% CI as 42,49) versus 80 (95% CI as 72,87) in subgroup II (P P < 0.001 for PT versus non-PT in both subgroups). The present study indicates that body iron overload resulting from excess intake of iron may be associated with qualitative defects in cell mediated immunity at early stage of HIV-1 infection that may facilitate subsequent acquisition of pulmonary tuberculosis, shorter ARI free duration and reduced survival.展开更多

Methods: From February 2018 to March 2019, 40 patients with pulmonary tuberculosis (tuberculosis group) and 40 healthy persons (control group) were collected, the levels of TNF-α, IL-6 and IL-8 in serum were detected by enzyme-linked immunosorbent assay (ELISA);the expressions of LncRNA-PACER and NFκB1 mRNAs in PBMCs were detected by real-time fluorescence quantitative PCR;Western blot was used to detect the expressions of NFκB1 and COX 2 in PBMCs;Pearson method was used to analyze the expressions of LncRNA-PACER and NFκB1 in PBMCs of patients with pulmonary tuberculosis, and the expressions of LncRNA-PACER and NFκB1 in PBMCs of patients with pulmonary tuberculosis were analyzed. Results: Compared with the control group, the expressions of TNF-α, IL-6 and IL-8 in the serum of patients with pulmonary tuberculosis was significantly increased (P<0.05), and the expressions of LncRNA-PACER, NFκB1 mRNAs, proteins and COX-2 protein in PBMCs were significantly increased (P<0.05). The expressions of LncRNA-PACER and NFκB1 proteins in PBMCs were related to the number of pulmonary lesions and pulmonary cavity (P<0.05), and there was a positive correlation between the expression of LncRNA-PACER and the expression of NFκB1 mRNA in PBMCs of patients with pulmonary tuberculosis (r = 0.873, P<0.05). Conclusions: The expressions of NFκB1 and LncRNA-PACER in PBMCs of patients with pulmonary tuberculosis are significantly increased, they are positively correlated and both of them are related to the occurrence and development of pulmonary tuberculosis.展开更多
