Introduction:
Apart from masking the diagnosis of AIDS in patients with HIV/AIDS, human T-cell lymphotropic virus (HTLV), when present, also increases the risk of myelopathies and neurological disease in these patients.
Methods:
Disease prevalence was estimated by ELISA and confirmed by Western blot.
Results:
The coinfection rate was 1.5% (11/720); 10 of 11 patients had HTLV-1, and the remaining one had HTLV-2. The majority were male, over 40 years old, and of pardo color (ethnicity).
Conclusions:
There was no association between the risk factors examined and HTLV/HIV coinfection. This is the first study to report the occurrence of HTLV-2 in Pernambuco.

The nitrous acid is unstable. Hence, it is formed in situ from a solution of sodium nitrite and cold aqueous acids such as hydrochloric or sulfuric acid. In an acidic solution, the –OH group of nitrous acid undergoes protonation to give oxonium ion, followed by...
