Popis: | Involvement of the digestive system in patients with acquired immunodeficiency syndrome (AIDS) is frequent and many changes in these patients are diagnosed only at autopsy. There are few studies of autopsy with detailed analysis of this system and only one was conducted in Brazil. We evaluated each segment of the digestive system in 93 consecutive autopsies of patients infected with human immunodeficiency virus (HIV) and the importance of these lesions to death. Of these, 90 (96.8%) patients had AIDS. We reviewed medical records, autopsy reports and histological sections from tongue to rectum stained with hematoxylin-eosin. When necessary, we analyzed special stains and immunohistochemistry to investigate infections. There was damage to the digestive system in 73 (78.5%) cases. The most common infections were candidiasis (42%), cytomegalovirus (29%), histoplasmosis (11.8%), toxoplasmosis (9.7%) and mycobacterial infection (9.7%). Malignancies were rare, present in four (4.3%) cases (two Kaposi's sarcoma, one adenocarcinoma and one metastatic embryonal carcinoma). All segments showed lesions: tongue (48.6%), esophagus (44.8%), stomach (44.7%), colon (43.2%) and small intestine (28.9%). The lesions found were immediate cause of death in five (5.4%) cases. In another 36 (38.7%) cases the basic disease was systemic and also compromised the digestive system. Envolvimento do sistema digestório em pacientes com síndrome da imunodeficiência adquirida (AIDS) é frequente e muitas alterações nesses pacientes são diagnosticadas apenas à autopsia. Há escassos estudos de autopsia com análise detalhada desse sistema e apenas um deles foi realizado no Brasil. Neste estudo avaliamos cada segmento do sistema digestório em 93 autopsias consecutivas de indivíduos infectados pelo vírus da imunodeficiência humana (HIV) e a importância dessas lesões para o óbito. Desses, 90 (96,8%) pacientes apresentavam AIDS. Revisamos prontuários médicos, relatórios de autopsias e cortes histológicos da língua ao reto corados pela técnica de hematoxilina-eosina. Quando necessário, analisamos colorações especiais e imuno-histoquímica para pesquisar infecções. Havia lesões no sistema digestório em 73 (78,5%) casos. As alterações mais comuns foram infecciosas: candidíase (42%), citomegalovirose (29%), histoplasmose (11,8%), toxoplasmose (9,7%) e infecção por micobactérias (9,7%). Neoplasias malignas foram raras, presentes em quatro (4,3%) casos (dois sarcomas de Kaposi, um adenocarcinoma gástrico e um carcinoma embrionário metastático). Todos os segmentos apresentaram lesões: língua (48,6%), esôfago (44,8%), estômago (44,7%), intestino grosso (43,2%) e intestino delgado (28,9%). As lesões encontradas foram causa imediata do óbito em cinco (5,4%) casos. Em outros 36 (38,7%) casos a doença básica era sistêmica comprometendo, também, o sistema digestório. |
