Evaluation of Intestinal Parasites and Some Clinical Symptoms in Children With Diarrhea

Abstract

Objective: This study aimed to determine the frequency of intestinal parasites in children who were presented to health centers with a complaint of diarrhea and to reveal the importance of these parasites. Methods: The study was conducted on children within the age range of 1-16 who were presented to Iğdır State Hospital and Private Bulut Hospital between 2020 February-April 2020 with a complaint of diarrhea. A total of 300 children comprising 141 girls and 159 boys were enrolled in the study. The control group was composed of 100 children (girls=50, boys=50) without any chronic disease and diarrhea. Stool samples were evaluated by the native-Lugol method and the modified acid-fast staining method. Results: Intestinal parasite positivity was found in 105 (35%) out of the 300 children in the patient group and in 17 (17%) out of the 100 children in the control group. In terms of parasitic positivity, a statistically significant difference was found between children with diarrhea and the healthy control group (p=0.001). Blastocystis hominis (13%), Cryptosporidium spp. (3%), and Giardia intestinalis (2%) were found in the patient group. Intestinal parasitic positivity was found in 30.2% and 40.4% of the boys and girls in the patient group, respectively, whereas it was found in 14% and 20% of the boys and girls in the control group, respectively. When evaluated statistically according to gender, a significant difference (comparison for boys: p=0.008; comparison for girls: p=0.004) was noted between the patient group and control group for each gender. In terms of the relationship between the frequency of parasites and some living conditions of the patients, a statistically significant relationship was found in the comparison of “whether or not livestock” (p=0.004) and “whether there is a sewerage network” (p=0.002). Additionally, a significant difference was found between parasitic positivity and abdominal pain (p=0.008) and nausea (p=0.003). Conclusion: The present study concludes that children with clinical symptoms, such as diarrhea, abdominal pain, and nausea, should be evaluated for intestinal parasites. Furthermore, it has been understood that intestinal parasites remain an important health problem among the pediatric cohort. © 2022 Turkish Society for Parasitology.
