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.
stitistics:Blastocystis was detected by qPCR in 23.2% (13/56) of patients with IBS and 16.1% (9/56) of control subjects . Interestingly, when considering only males, the prevalence of the parasite in the IBS group (36.8%, 7/19) was significantly higher (p = 0.017) than in the control group (4.8%, 1/21). In contrast, the prevalence of Blastocystis sp. in females did not significantly differ between both groups (p = 0.559). Similar results were observed when considering only the IBS-C subgroup.
