Intestinal Parasites Infection among Immunocompromised Patients in Riyadh, Saudi Arabia

This study was conducted to determine the prevalence of intestinal parasites among immunocompromised patients in Riyadh, Saudi Arabia. Fecal samples were collected from 136 immunocompromised patients (52 females and 84 males), aged 2 to 69 years. Specimens were fixed with 10% formalin for 30 min (2-3 g fecal^-1) and then concentrated by a formalin-ether sedimentation technique. Samples were examined as wet saline mounts and in iodine preparation for detection of protozoan oocysts, cysts, helminthic eggs and larvae. Permanent stained smears were performed for intestinal coccidian parasites by the modified Ziehl-Neelsen technique and the modified trichrome stain. Intestinal parasites were detected in 54 (39.7%) most of them (25.7%) were with diarrhea. More specifically the following parasites were detected Cryptosporidium parvum 11(8.1%), Giardia lamblia 9 (6.6%), Cyclospora cayetanensis 8 (5.9%), Blastocystis hominis 7 (5.2%), Entamoeba histolytica 7 (5.2%), Entamoeba coli 5 (3.7%), Strongyloides stercoralis 3 (2.2%), Ascaris lumbricoides 1 (0.7%), Hymenolepis nana 1 (0.7%), Dicrocoelium dendriticum 1 (0.7%) and Hook worm 1 (0.7%). The most common parasite associated with diarrhea in patients, was C. parvum (p<0.001), followed by G. lamblia, C. cayetanensis and E. histolytica_. However, differences between different age groups were statistically non-significant. Similarly, no significant difference in the infection rate were found between male and female patients.
