title: [Enteric parasites and AIDS in Haiti: utility of detection and treatment of intestinal parasites in family members].
abstract: Intestinal parasites and human immunodeficiency virus (HIV) are major health problems in Haiti. Both entities are known to interact strongly with cell-mediated immunity. The purpose of this study undertaken in Port-au-Prince, Haiti was to evaluate the risk of enteric parasite transmission between HIV-infected patients and family members. Routine examination of stool specimens for parasites was conducted in 90 HIV-infected undergoing treatment for intestinal disorders due mainly to Cryptosporidium sp. (62%) and 123 healthy family member volunteers. A stool sample preserved in 10% formalin solution was examined to detect protozoa (MIF, modified Ziehl-Neelsen stain, Uvibio fluorescence technique, Weber stain) and helminth ova (Bailenger technique). In addition to Cryptosporidium sp., 14 parasitic species were identified: 6 Rhizopoda, 3 Flagellata (including Giardia duodenalis), 1 Coccidia (Cyclospora cayetanensis), 3 Nematoda (mainly Ascaris lumbricoides) and 1 Cestoda (Hymenolepis nana). This is the first time that 5 protozoa, i.e., Blastocystis hominis, Entamoeba hartmanni, E. polecki, Chilomastix mesnili, and Enteromonas hominis, have been reported in Haiti. As expected, enteric parasites were less common in HIV-infected subjects undergoing medical treatment (11.1%) than in uninfected family members (41.5%) (p = 0.0000). Multiple intestinal parasitism (infection by 2 to 4 parasites) was observed in 19.5% of family members. The findings of this study indicate that detecting and treating intestinal parasites in subjects living in close contact with HIV-infected patients as well as informing family members of the importance of personal hygiene in Haiti are highly recommended measures to preserve the health of AIDS patients.
