Background and study aim: Gastrointestinal parasites cause infectious diseases. Parasitic infection of duodenum is a relevant cause of its inflammation and appearance of upper GIT manifestation, especially in developing countries. Examination of duodenal aspirates can be very helpful in diagnosing intestinal infection because it eliminates some of the problems inherent in stool examination. The aim of this study was to estimate the prevalence of parasites in duodenal aspirate obtained by upper gastrointestinal tract endoscopy.
Subjects and methods: This cross-sectional study was conducted from March 2017 toMarch 2018 in sohag university hospital and Center of the digestive system. It was done on 100 patients who underwent Esophago-gastro-duodenoscopy. A total of 100 duodenal aspirate samples were collected from patients were subjected to Esophagogastroduodenoscopy for diagnostic or therapeutic reason. All cases were reviewed as regard age, sex. Cases with parasitic infestations were characterized regarding the mentioned variables.
Results: 60 % of duodenal aspirate samples were positive. Monoparasitized patients constituted 38% (38/100) of patients while 22% were polyparasitized. There were 44 patients (44%) of Cryptosporidium infection, 21 patients (21%) of Blastocystis hominis infection, 11 patients (11%) of Cyclospora infection, 8 patients (8%) of Giardia lamblia infection.
Conclusion:We concluded that the duodenal aspirate samples obtained during gastrointestinal endoscopic procedures helped in diagnosing the parasites.
Background and study aim: Giardiasis is a gastrointestinal disease, caused by the protozoan parasites Giardia lamblia. This infection occurs through ingestion of contaminated water or food by Giardia lamblia cysts. The aim of this study was to correlate between the presence of Giardia lambilia and different gastrointestinal symptoms.
Bronchial asthma is a chronic inflamatory disorder of the airways characterized by airway hyperresponsiveness and reversible airflow obstruction that fluctuates over time. Parasitic infection is one of the environmental factors associated with a small increase in bronchial asthma risk. In the present study, 200 stool samples were collected from patients suffering from bronchial asthma and 200 stool samples from non-asthmatic healthy volunteers as control group. The collected samples were preserved in 10%formalin and examined macroscopically, microscopically by direct smear and formol ether sedimentation test. It was found that 12 out of 200 cases (6%) wereinfected with Ascaris lumbricoides in asthmatic group and 2 out of 200 cases (1%) in control group with P-value = 0.007 * indicating statistically significant difference between cases and control group
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
