Abstract

BackgroundOne of the major health problems among HIV seropositive patients is superimposed infection due to the defect of immunity. Furthermore, intestinal parasite infection, which is also one of the basic health problems in tropical region, is common in these patients. In this study, a cross sectional study to document the prevalence of intestinal parasitic infection in Thai HIV-infected patients with different immune status was performed.MethodsA study of stool samples from 60 Thai HIV-infected patients with different immune status was performed at King Chulalongkorn Memorial Hospital, Thailand. Each patient was examined for CD4 count and screened for diarrheal symptoms.ResultsThe prevalence of intestinal parasitic infection among the HIV-infected patients in this study was 50 %. Non- opportunistic intestinal parasite infections such as hookworms, Opisthorchis viverrini and Ascaris lumbricoides were commonly found in HIV-infected people regardless of immune status with or without diarrheal symptoms. Opportunistic intestinal parasites such as Cryptosporidium, Isospora belli, Microsporidia and Strongyloides stercoralis infection were significantly more frequent in the low immunity group with diarrhea.ConclusionTherefore, opportunistic intestinal parasite infection should be suspected in any HIV infected patient with advanced disease presenting with diarrhea. The importance of tropical epidemic non-opportunistic intestinal parasite infections among HIV-infected patients should not be neglected.

Summary

Introduction

One of the major health problems among HIV seropositive patients is superimposed infection due to the defect of immunity. A cross sectional study to document the prevalence of intestinal parasitic infection in Thai HIV-infected patients with different immune status was performed. In Thailand, a tropical country in Southeast Asia, HIV infection is a major problem, like in other regional countries. It has been estimated that a million people are infected with HIV infection in Thailand [1]. Intestinal parasite infection, which is one of the basic health problems in tropical region [2], is common in these patients
