Investigating the Prevalence of Intestinal Parasites in Immunocompromised Patients in Bushehr Province, Southwest Iran: A Conventional and Molecular Study.

OBJECTIVE

The aim of this study was to determine the status of intestinal parasitic infections in immunocompromised patients in Bushehr province, southwest Iran by conventional and molecular methods.

METHODS

A total of 201 stool samples were collected from kidney transplant recipients, AIDS patients and patients under chemotherapy. Samples were collected from healthy people as the control group. The specimens were tested using various conventional methods. Polymerase chain reaction (PCR) testing was performed on samples identified as positive for Coccidia by direct microscopic examination.

RESULTS

Approximately 32.45% were infected with at least one type of intestinal parasite. The highest (46.8%) and lowest rates of infection (24%) were observed in AIDS and chemotherapy patients, respectively, while the infection rate of the control group was 16%. spp. and spp. were observed in all patient groups, and Sarcocystis spp. sporocysts were detected in one of the transplant recipients. All identified coccidia were confirmed by PCR. There was a significant relationship between the rate of intestinal parasite infection and certain variables.

CONCLUSION

Given the potential risk of certain intestinal parasites in people with immune deficiency, it is recommended that diagnosis of parasitic infections in such patients be based on specific parasitological methods. Thus, it is advisable that physicians refer them to a parasitology laboratory prior to drug administration.
