Blastocystis hominis is a microscopic organism that may be found in the stools of healthy people who aren't having any digestive symptoms. Blastocystis hominis is also sometimes found in the stools of people who have diarrhea, abdominal pain or other gastrointestinal problems.
Symptoms: Signs and symptoms that might be associated with blastocystis include: Diarrhea Nausea Abdominal cramps Bloating Excessive gas (flatulence) Hives Loss of appetite Fatigue
Treatment:Treatment of Blastocystis infection remains a complicated issue. Because there is still a great deal of debate about the true pathogenicity of Blastocystis, there is still much debate about the need for treatment. Further knowledge about the genotyping and subtyping of Blastocystis and the impact that various subtypes may have on pathogenicity and antimicrobial efficacy is still being sought . In a symptomatic patient, isolation of cysts in stool specimens should trigger a thorough evaluation for other causes of the patient’s gastrointestinal tract complaints, given the possibility for coinfection with other pathogens.
statistics:Of the 59 patients, stool samples of 13 patients (22.1%) were positive for parasites. These were B. hominis (13.6%), Strongyloides stercoralis larvae (1.7%), Giardia lamblia cysts (1.7%), and non-pathogenic protozoa, ie Endolimax nana cysts (5.1%). The prevalence rate of parasitic infections in the control group (20%) was not statistically different from the patients. There was no statistical difference between B. hominis infection in IBS patients and control was found in this study (p = 0.87). In the IBS group, B. hominis infection predominated (13.6%), while other parasitic infections were found in 8.5%.
