|Abstract:||BACKGROUND: The human T-cell leukaemia virus type 1 (HTLV-1) subtype c is endemic to central Australia. We report the first large-scale, community-based, health survey of HTLV-1 and its disease associations in this setting. METHODS: Aboriginal community residents aged >2 years in seven remote communities were invited to do a health survey that included a questionnaire, spirometry and clinical examination by a physician blinded to HTLV-1 status, clinical records and spirometry results. Blood was drawn for HTLV-1 serology and proviral load (PVL). Pulmonary disease was assessed clinically and spirometrically and, where records were available, radiologically after the clinical assessment. Associations between specific diseases and HTLV-1 status were determined using logistic regression, adjusting for available confounders. RESULTS: Overall, 579 residents (children aged 3-17, 164; adults, 415) were examined (37.7% of the estimated resident population). HTLV-1 prevalences for children and adults were 6.1% and 39.3%, respectively. No associations were found between HTLV-1 and any assessed clinical condition among children. Chronic pulmonary disease and gait abnormalities were more common among adults with HTLV-1 infection. Adjusted odds ratios (aOR)(95% CI) among participants with PVL ≥ 1000 per 10 5 PBL were 7.08 (2.67, 18.74; p<0.001), 9.81 (3.52, 27.35; p<0.001) and 14.4 (4.99, 41.69; p<0.001) for clinically defined chronic pulmonary disease, moderate-severe expiratory airflow limitation and radiologically determined bronchiectasis/bronchiolitis, respectively, and 5.21 (1.50, 18.07; p=0.009) for gait abnormalities. CONCLUSION: In the first study of HTLV-1 disease associations based on community recruitment and blinded assessment, HTLV-1 infection was strongly associated with pulmonary disease and gait abnormalities.|
