Epidemiology of Intestinal Parasites in a University Hospital in Northern Cyprus: A 4-year Retrospective Experience

Abstract

Objective:Intestinal parasitic infections (IPI) are considered as one of the most important public health problems that cause morbidity and mortality. For this reason, to determine their prevalence it is critical for prevention. This study aimed to determine the prevalence of intestinal parasites.Methods:In our study, a total of 4.957 patients registered to our hospital with gastrointestinal symptoms between January 2016 and December 2019 were retrospectively analysed. Their stool samples were examined macroscopically and microscopically. In the microscopy, native-lugol and formol ethyl acetate concentration methods were used. Crypto-Giardia-Entamoeba antigen test was applied. All cases were evaluated in terms of age, gender, year and season.Results:In our study group, 239 (4.8%) patients were detected as positive for intestinal parasites. Among these patients, 129 (54%) were male and 110 (46%) were female. No statistically significant difference was found between IPI and gender (p=0.228). Blastocystis hominis (76.2%) and Giardia intestinalis (12.1%) were the most common parasites. According to age groups, most intestinal parasites are found in 16-45 years old and least in 0-15-years-old (p=0.0001). A significant increase was found in positive intestinal parasite cases especially after 2018 (p=0.0001). Our study determined that intestinal parasites were observed most frequently in autumn (p=0.033).Conclusion:The prevalence of IPI in our country is low. However, due to the increasing trend of IPI since 2018, necessary measures must be implemented to prevent further increase in the number of cases. In addition, reasons behind the rising cases of intestinal parasites during the autumn months in which rainfall begins require further investigation.
