ABSTRACT

There is a high prevalence of osteoporosis in HIV-infected patients. Initially described in HIV-positive men, studies have also demonstrated a high prevalence of osteoporosis in HIV-infected women. It would appear that antiretroviral therapy (ART) plays an important role in the pathogenesis of osteoporosis in HIV-infected patients, although little is known about its importance in relation to osteoporosis and fractures in HIV-positive women. The aim of this systematic review was to evaluate the frequency of bone loss, bone mineral density (BMD) and fractures in HIV-positive women taking ART or protease inhibitors (PI). After screening 597 citations from the databases of PubMed, EMBASE and Lilacs, five studies were selected for the review. A difference was demonstrated of over 3 percent in the BMD at the femoral neck of HIV-positive women taking PI/ART. No difference was registered in the BMD at the lumbar spine between users and non-users of PI/ART. The lack of studies has made it impossible to reach any conclusion regarding the occurrence of fractures.


A prevalência de osteoporose é elevada em indivíduos infectados pelo HIV. Inicialmente descrita em homens HIV-positivos, estudos demonstraram alta prevalência de osteoporose também em mulheres HIV-positivas. A terapia antirretroviral parece exercer papel importante na patogênese da osteoporose dos indivíduos com HIV. Pouco se sabe sobre sua importância para a osteoporose e fraturas nas mulheres HIV-positivas. Esta revisão objetivou avaliar a frequência de perda de massa óssea, densidade mineral óssea (DMO) e fraturas em mulheres HIV-positivas em uso de terapia antirretroviral (TARV) ou inibidores de protease (IP). Após busca nos bancos de dados PubMed, EMBASE e Lilacs, de 597 citações, cinco estudos permaneceram na revisão. Demonstrou-se haver uma diferença superior a 3 por cento na DMO no colo do fêmur de mulheres HIV-positivas em uso de IP/TARV. Não se evidenciou diferença na DMO da coluna lombar entre usuárias e não usuárias de IP/TARV. A escassez de estudos impossibilitou qualquer conclusão sobre a ocorrência de fraturas.
