[Parasites found in HIV-seropositive patients]

Area of Science:

• Medical Parasitology
• Infectious Diseases
• Immunocompromised Host Research

Context:

• Human Immunodeficiency Virus (HIV) infection significantly compromises the immune system, increasing susceptibility to opportunistic infections.
• Patients with advanced HIV disease (Centers for Disease Control and Prevention stages 3 and 4) are at high risk for parasitic and fungal infections.
• The study focuses on a seropositive HIV population exhibiting clinical characteristics of advanced disease.

Purpose:

• To investigate the prevalence and types of parasitic infections in the gastrointestinal tract of advanced HIV patients.
• To determine the incidence of Pneumocystis pneumonia (PCP) in the same patient cohort using respiratory samples.
• To correlate parasitic and PCP findings within this vulnerable population.

Summary:

• Over 41 months, 212 fecal samples from 135 advanced HIV patients were analyzed. 53.33% tested positive for enteroparasites, with Blastocystis hominis (26.66%) and Entamoeba coli (13.33%) being most common.
• Respiratory samples (17 bronchoalveolar lavages and 194 sputa) were examined for Pneumocystis jirovecii. PCP was diagnosed in 47% of BAL and 22.68% of sputa, totaling 34.68% of respiratory cases.
• Multiple parasitic infections were observed, with 46 patients having one, 19 having two, 5 having three, and 2 having four different parasites.

Impact:

• Highlights the significant burden of parasitic infections in advanced HIV patients, necessitating targeted diagnostic and treatment strategies.
• Underscores the high prevalence of Pneumocystis pneumonia in this population, emphasizing the importance of prophylaxis and early detection.
• Provides crucial epidemiological data for public health initiatives and clinical management guidelines for immunocompromised individuals.
