[HIV infection and "malignant" strongyloidiasis]

Area of Science:

• Parasitology
• Infectious Diseases
• Immunocompromised Hosts

Context:

• Strongyloides stercoralis infection is a significant concern in immunocompromised individuals.
• Acquired immunodeficiency syndrome (AIDS) patients are immunocompromised, yet disseminated strongyloidiasis is infrequently reported in this population.
• Geographic overlap exists between HIV infection and strongyloidiasis in endemic regions.

Purpose:

• To investigate the reported incidence and clinical characteristics of disseminated Strongyloides stercoralis infection in patients with acquired immunodeficiency syndrome (AIDS).
• To explore the potential association between human immunodeficiency virus (HIV) infection and the dissemination of Strongyloides stercoralis.
• To evaluate the implications of observed associations for the classification of AIDS-related opportunistic infections.

Summary:

• Disseminated Strongyloides stercoralis infection, typically seen in immunocompromised patients, has been reported in only six cases among individuals with AIDS.
• Clinical presentations of disseminated strongyloidiasis in AIDS patients lack unique features, often co-occurring with other opportunistic infections.
• The low reported incidence led to the exclusion of extra-intestinal strongyloidiasis from the revised AIDS classification, questioning a direct link with HIV.

Impact:

• Highlights a potential disconnect between the expected and observed incidence of disseminated strongyloidiasis in AIDS patients.
• Suggests that human immunodeficiency virus (HIV) may not be a significant predisposing factor for Strongyloides stercoralis dissemination.
• Informs clinical awareness and diagnostic considerations for Strongyloides stercoralis in immunocompromised individuals, including those with AIDS.
