Are HTLV-II-seropositive injection drug users at increased risk of bacterial pneumonia. abscess, and lymphadenopathy?

Disease associations of HTLV-II are poorly defined, despite a high seroprevalence among injection drug users (IDU). One hundred twenty-four HTLV-II-seropositive emergency room and clinic patients were matched by age, sex, and clinic to 120 HTLV-I/II-seronegative patients. Medical records were reviewed blinded to HTLV-11 status, and International Classification of Disease 9th Clinical Modification (ICD-9CM)--coded diagnoses were compared between seropositive patients and controls.
