BACKGROUND: A link between chronic inflammation and several noncommunicable diseases (NCDs) has been established. Although chronic infection with the human T-cell leukemia virus type 1 (HTLV-1) is the recognized cause of several inflammatory diseases and these are associated with a high number of HTLV-1-infected cells in peripheral blood (proviral load [PVL]), possible interactions between PVL and NCDs have not been studied at a community level.
METHODS: Adult Aboriginal residents of 7 remote communities were invited to complete a health survey between 25 August 2014 and 30 June 2018. Blood was drawn for HTLV-1 serology and PVL, and relevant medical conditions were obtained from health records. Associations between HTLV-1 PVL and diabetes, chronic kidney disease (CKD), and coronary artery disease (CAD) were determined using logistic regression, adjusting for available confounders.
RESULTS: Among 510 participants (56% of the estimated adult resident population, 922), 197 (38.6%) were HTLV-1-infected. A high HTLV-1 PVL was associated with a 2-fold increase in the odds of diabetes and CKD (diabetes, adjusted odds ratio [aOR], 1.95; 95% confidence interval [CI], 1.06-3.61; P = .033 and CKD: aOR, 2.00; 95% CI, 1.03-3.8; P = .041). A nonsignificant association between high PVL and CAD (aOR, 7.08; 95% CI, 1.00-50.18; P = .05) was found for participants aged <50 years at the time of angiography.
CONCLUSIONS: In a community-based study in central Australia, people with HTLV-1 who had high HTLV-1 PVL were more likely to have diabetes and CKD. These findings have potential clinical implications.
