Prevalence and Physiological Effect of Blastocystis Hominis on Lipid Metabolism, Magnesium, and Zinc Levels in Diarrheal Patients
Abstract
Blastocystis hominis is a microscopic single-celled organism commonly known as a protist or parasite. It was first discovered in the early 20th century by a Scottish scientist named Alexei Pavlovich Alexeieff. Blastocystis hominis is found in the intestines of humans and other animals, where it can colonize the gastrointestinal tract. The objective of this study was to examine the presence of the Blastocystis hominis parasite in the stool samples of patients experiencing diarrhea and to explore its potential physiological effects. The study involved two groups: 1-the patients group, which consisted of 220 samples who suffered from diarrhea, and abdominal pain and 2-the control group, which consisted of 100 samples of healthy individuals. The age range of participants ranged between 4-40 years. The outcome indicated that the vacuolar form was the most common morphological appearance observed in the stool. The result showed non-significant difference was observed (P>0.05) for all ages. Furthermore, a statistically significant difference (P≤0.05) was observed in the infection rate between males (58.00%) and females (42.00%). The physiological examinations were conducted using Spectrophotometer revealed notable findings. There was a significant increase (P≤0.01) in the levels of cholesterol, low-density lipoproteins-cholesterol (LDL), very low-density lipoproteins (VLDL), and triglycerides (TG), in patients with diarrhea infected with B. hominis compared to the control group. Conversely, concentrations of magnesium, zinc, and high-density lipoproteins (HDL) showed a significant decrease (P≤0.01) in the same patient group compared to the control group.
