Analyzing the prevalence of proctological diseases in HIV-positive and -negative patients

Abstract

Objective To compare proctological diseases in HIV-positive and -negative patients.

Method Prospective study conducted in the proctology outpatient clinic at Instituto de Infectologia Emílio Ribas from 2013 through 2019. All of them underwent anamnesis and proctological examination and were divided into two groups (HIV+ and HIV−). The groups were then compared with regard to age, sex, diagnosis, and whether or not there was any indication for surgery.

Results 485 HIV + patients (41.9%) (Group I) and 672 HIV− (58.1%) (Group II). The mean age in Group I was 42.8 years, and 404 (83.3%) of the patients were males. In Group II, the mean age was 48.3 years, and 396 (59%) patients were females. In comparing the groups, a statistically significant difference was found regarding sex, age, and diagnosis. The incidence of hemorrhoid and anal skin tags was higher in group II and that of condyloma acuminata was higher in in Group I (p < 0.001). In Group I, condyloma acuminata was more prevalent, but in those with CD4 levels above 500 cells/mm³, the diagnoses were more similar to those in the population without HIV.

Conclusions Proctological diseases were found to be similar but have different incidences. The incidences of diseases in HIV− and + patients tend to approach each other as CD4 level increases.

Resumo

Objetivo Comparar as doenças proctológicas nos pacientes HIV positivos e negativos.

Método Estudo prospectivo realizado no ambulatório de proctologia do Instituto de Infectologia Emílio Ribas de 2013 a 2019. Todos foram submetidos a anamnese e exame proctológico, e divididos em dois grupos (HIV+ e HIV−) sendo comparados em relação a idade, sexo, diagnóstico e se havia ou não indicação cirúrgica.

Resultados 485 pacientes HIV+ (41.9%) (Grupo I) e 672 HIV negativos (58.1%) (Grupo II). A média de idade do Grupo I foi 42.8 anos sendo 404 (83.3%) do masculino. No grupo II, a média de idade foi de 48.3 anos, sendo 396 (59%) do sexo feminino. Comparando os grupos, houve diferença estatisticamente significante em relação ao sexo, idade e diagnóstico. Houve maior incidência de hemorróida e plicoma no Grupo II e condilomas acuminados no Grupo I (p < 0.001). No Grupo I, o condiloma acuminado foi mais prevalente, porém naqueles com CD4 acima de 500 células/mm³, os diagnósticos se aproximaram da população sem HIV.

Conclusão As doenças proctológicas foram semelhantes, com incidências diferentes. A incidências das doenças de pacientes HIV− e + tendem a se aproximar na medida que o nível do CD4 aumenta.
