C - reactive protein and interleukin-6 levels among human immunodeficiency virus -infected patients with dysglycemia in Tanzania

BackgroundChronic inflammation has been associated with dysglycemia among people living with HIV (PLHIV). There is however, limited data regarding this phenomenon in sub-Sahara Africa (SSA). Therefore we assessed the levels of C-reactive protein (CRP) and Interleukin 6 (IL-6) on a cohort of PLHIV and its associations with dysglycemia in Tanzania.MethodsWe conducted a cross-sectional study at the Infectious Disease Clinic (IDC) in Tanzania from March to May 2018. Purposive sampling was used to identify participants who had an undetectable viral load, were on 1st line anti-retroviral therapy (ART) and had an overnight fast. The WHO stepwise approach for non-communicable disease (NCD) surveillance was used to collect data. Fasting blood glucose and blood glucose after 75g oral glucose load was measured, and Enzyme-linked immunosorbent assay (ELISA) was used to test for inflammatory markers (IL-6 and CRP). Associations were explored using the Chi square test and binary logistic regression was performed to estimate the odds ratios. A p-value less than 0.05 was considered statistically significant.ResultsA total of 240 participants were enrolled. Forty two percent were overweight/obese (>25kg/m(2)), 89% had a high waist to height ratio. The median ART duration was 8(5-10) years. The prevalence of dysglycemia among our cohort of PLHIV was 32%. High CRP was associated with a 2.05 increased odds of having dysglycemia OR 2.05 (1.15-3.65) (p=0.01). Taking stavudine was associated with a 1.99 odds of having dysglycemia OR 1.99 (1.04-3.82) (p=0.03).We did not find a significant association between IL-6 and dysglycemia.ConclusionHigh CRP and taking stavudine were significantly associated with dysglycemia among PLHIV with undetectable viral load.
