Aim: Diseases caused by intestinal parasites are an important public health problem in our country as well as in the world. In this study, it was aimed to determine the distribution of intestinal parasites in patients applied to İnönü University Turgut Özal Medical Center Parasitology Laboratory with various gastrointestinal system complaints and to show their association with variables such as gender and year.
Materials and Methods: Stool samples of 15610 patients sent to the Parasitology Laboratory between January 2018 and March 2022 were included in the study. Stool samples of the patients were analyzed first macroscopically and then microscopically by native-lugol methods. Cellophane tape method was used in 917 patients according to the complaints of rectal itching and growth retardation. Demographic data of the patients were obtained through the hospital and laboratory information operating system.
Results: Intestinal parasites were detected in 5.5% (861) of the 15610 patients analyzed. Of 15610 stool samples, 7232 (46.33%) belonged to female and 8378 (53.67%) to male patients. When the distribution of intestinal parasites detected by years is analyzed, the highest number of patients and positivity rate were in 2018 [4265 (28.92%) of 4526 samples were negative, and 261 (30.31%) were positive], and the lowest was in 2022 (679(4.60%) of 712 samples were negative, and 33 (3.83%) were positive). When the distribution of the positivity rate according to the parasites wasanalyzed, 221 (25.67%) Giardia intestinalis, 201 (23.35%) Blastocystis hominis, 157 (18.23%) Entamoeba histolytica / Entamoeba dispar, 179 (20.79%) Entamoeba coli, 57 (6.62%) Enterobious vermicularis, 19 (2.21%) Trichomonas hominis, 17 (1.97%) Iodeomoeba butschlii and 10 (1.16%) Taenia saginata were found.
Conclusion: Although the frequency of parasite infection in patients applied to the laboratory was found to be lower than in previous years, another reason for this is that people have started to pay more attention to hygiene conditions due to the coronavirus (COVID-19) epidemic in our country. Although there has been a statistical decrease despite the past years and it shows that intestinal parasite infections continue to be an important public health problem in our region, it is also important in terms of revealing the decrease in incidence.
