ABSTRACT
Abdominal symptoms frequently affect patients with AIDS. Acute abdominal pain is a diagnostic challenge that may require elective or urgent surgical treatment, although information about the latter is scarce. In this study we analyzed the clinical findings and follow-up of acute abdominal pain complicating patients with AIDS. In a two-year period, we collected several variables from patients with AIDS and acute abdominal pain: demographic, laboratory, clinical symptoms, initial diagnosis, surgical findings, post-surgical and histopathological diagnosis and post-surgical complications. From 232 hospitalized patients, 34 had acute abdominal pain: 32 male and 2 women (median age = 32 years; range 26 to 58 years). Twenty-two patients required surgical treatment. Eight patients had a post-surgical complication; in five of them, six surgical re-interventions were performed. Three deaths occurred in the 30-day period after surgery. Survival for patients conservatively treated was 4 months (1 to 17 months), vs. 6.5 months (1 to 20 months) in the surgically treated group. Physicians should be aware about the several diagnostic possibilities of acute abdominal pain complicating patients with AIDS. Delay of surgery in these patients may be lethal. Surgery has an important role in the integral treatment of patients with AIDS.

Los síntomas abdominales son frecuentes en el SIDA y el dolor abdominal es un reto diagnóstico que puede requerir cirugía electiva o urgente aunque la información acerca de esta última es pobre. En este estudio analizamos los hallazgos clínicos y evolución de pacientes con SIDA y dolor abdominal agudo. En un periodo de dos años, recolectamos variables demográficas y de laboratorio, síntomas clínicos, diagnóstico inicial, hallazgos quirúrgicos, diagnóstico postquirúrgico, hallazgos histopatológicos y complicaciones postoperatorias de pacientes con SIDA y dolor abdominal agudo. De 232 pacientes hospitalizados, 34 tuvieron dolor abdominal agudo: 32 hombres y 2 mujeres (mediana de edad = 32 años; intervalos 26 a 58). Veintidós pacientes requirieron manejo quirúrgico. Ocho pacientes presentaron complicaciones postquirúrgicas; cinco requirieron seis segundas intervenciones. Ocurrieron tres muertes en los 30 días luego de la cirugía inicial. La supervivencia para los pacientes tratados médicamente fue 4 meses (1 a 17), contra 6.5 meses (1 a 20) del grupo quirúrgico. El médico debe estar alerta acerca de las posibilidades diagnósticas del enfermo con SIDA y dolor abdominal agudo. Demorar la cirugía puede ser letal. La cirugía tiene un papel importante en el tratamiento integral del paciente con SIDA.

Thrombosis has been considered an uncommon complication in patients with AIDS. In a 42-month period, 28 adult male homosexuals with AIDS experienced 34 thrombotic events. All but three received HAART regimen, two a successful round of double nucleoside analog therapy, and one patient received no treatment. Median age of group was 38.5 years (range, 24 to 56 years). Median time from HIV infection to thrombosis was 40.5 months (range, 3 to 108 months). No patient had previous thrombosis, family history of thrombosis, or prothrombotic conditions. There were 31 deep vein thromboses, two pulmonary thromboembolisms, and one renal vein thrombosis. Six patients had two thrombotic events. The rate of thrombosis during the 42-month study period was 1.52% (cumulative incidence = 0.30%/year), while the rate of thrombosis in 600 patients before the era of protease inhibitor therapy was 0.33% (cumulative incidence approximately 0.055%/year) (p < 0.001). Due to high incidence of thrombotic recurrences and hemorrhagic complications while using oral anticoagulants, acetylsalicylic acid was initiated; no thrombotic episodes were recorded while using this drug. Protein C and protein S deficiency were found in nine and two patients, respectively. Two patients had lupus anticoagulant and two activated protein C resistance (APCR) without FV Leiden mutation (APCR test was negative after initial screening). Fifteen patients had no thrombophilic abnormalities. These data suggest that protease inhibitors could be a risk factor for venous thrombosis not due to thrombophilic abnormalities but likely related to abnormalities in platelets or endothelium.

Se describen dos casos de pacientes diabéticos con cuentas normales de linfocitos TCD4+, que presentaban diarrea crónica y en los cuales se detectó Cryptosporidium en heces. En ambos casos las pruebas serológicas para VIH resultaron negativas. El hecho de que estos pacientes desarrollaran una patología que se observa comunmente en presencia de cuentas bajas de linfocitos TCD4+, sugiere que una alteración inmunológica distinta de la celular pudiera estar involucrada en la patogénesis de esta infección. Los autores sugieren que la búsqueda intencionada de Cryptosporidium debe considerarse en el estudio de la diarrea crónica del paciente diabético
