ABSTRACT
Some patients under antiretroviral therapy (ART) do not reach immune recovery when the viral load becomes undetectable. This is called discordant immunologic and virologic responses. Its prevalence varies between 8 percent and 24 percent. This study describes its prevalence and the characteristics of the affected subjects in the outpatient clinic of a Brazilian specialized-care center. Of 934 patients on ART, 536 had undetectable viral loads. Prevalence was 51/536 or 9 percent (95 percent confidence interval 6.6 percent to 11.4 percent). Median age at the beginning of ART was 37 years (interquartile range - IQR 31 to 45). Male gender and mixed race predominated (76.5 percent and 47.1 percent respectively). AIDS-defining illnesses were absent at the beginning of ART in 60.8 percent. Fifty-one percent were taking protease inhibitors, 43.2 percent Efavirenz and 5.8 percent both. Median time on ART was 36 months (IQR 17-81 months). Irregular treatment was recorded for 21.6 percent. ART had been modified for 63 percent prior to the study, and 15.7 percent had used monotherapy or double therapy. Median CD4 count was 255 cells/mm³ (IQR 200-284). Median viral load before ART was 4.7 log10 copies/mL (IQR 4.5-5.2). Discordant responders were not different from AIDS patients in general, but there was a high frequency of multiple schedules of treatment.
RESUMO
Alguns pacientes sob terapêutica antirretroviral (TARV) não obtêm recuperação imune quando a carga viral se torna indetectável. Isto é chamado resposta imunológica e virológica discordante. A prevalência varia entre 8 por cento e 24 por cento. Este estudo descreve sua prevalência e características dos afetados em ambulatório de um centro de cuidados especializados brasileiro. De 934 pacientes sob TARV, 536 tinham carga viral indetectável. A prevalência foi 51/536, ou 9 por cento (Intervalo de Confiança de 95 por cento de 6,6 por cento a 11,4 por cento). Idade mediana no início da TARV foi 37 anos (distância interquartílica - DQ 31 a 45). Gênero masculino e cor parda predominaram (76,5 por cento e 47,1 por cento, respectivamente). Doenças definidoras de Aids estavam ausentes no início da TARV em 60,8 por cento. Cinquenta e um por cento recebiam inibidores da Protease, 43,2 por cento Efavirenz e 5,8 por cento ambos. Tempo mediano de TARV foi 36 meses (DQ 17-81). Tratamento irregular foi registrado em 21,6 por cento. TARV havia sido anteriormente modificado em 63 por cento e 15,7 por cento haviam usado mono ou dupla terapêutica. A contagem mediana de CD4 foi 255 células/mm³ (DQ 200-284). O logaritmo mediano da carga viral antes do TARV foi 4,7 (DQ 4,5-5,2). Aqueles com resposta discordante não eram diferentes dos pacientes com AIDS em geral, mas houve alta frequência de múltiplos esquemas terapêuticos.
