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:In a study from Taiwan on 100 patients who had Blastocystis in the feces, all patients improved without specific treatment for Blastocystis. Further, on stool examination within 1 year of follow-up, the parasite was undetectable in 91.2% of patients despite their having no specific antiprotozoal treatment.
