Objective:

To explore the prevalence of Blastocystis subtypes in symptomatic patients and investigate their association with specific biomarkers of intestinal inflammation and metronidazole treatment outcomes.

Key Findings:
  • Blastocystis subtypes 3 and 4 were associated with increased intestinal inflammation.
  • Higher levels of fecal calprotectin were observed in patients infected with specific subtypes.
  • Metronidazole treatment showed variable efficacy depending on the Blastocystis subtype, indicating the need for tailored treatment approaches.
Interpretation:

The study suggests that different Blastocystis subtypes may contribute differently to intestinal inflammation and treatment responses, highlighting the need for subtype-specific management strategies.

Limitations:
  • The study lacked a non-infected control group, which may limit the interpretation of the findings.
  • Findings are exploratory and do not establish causal relationships.
  • Small sample size may limit generalizability.
Conclusion:

The findings indicate a potential link between specific Blastocystis subtypes and intestinal inflammation, warranting further research into subtype-specific treatment approaches to improve clinical outcomes.
