Abstract
CONTEXT: Hymenolepis diminuta infection is a very rare cestode infection. Until present, fewer than 500 cases have been observed worldwide. OBJECTIVE: The author performed a literature review on the reports of H diminuta in Thailand in order to summarize the characteristics of this infection among Thai patients. DESIGN: This study was designed as a descriptive retrospective study. A literature review of the papers concerning H diminuta infections in Thailand was performed. RESULTS: According to this study, there have been at least 6 reports in the literature of 10 individual cases of H diminuta infection, of which 1 case was lethal. Of 4 cases that documented patients' age, the ages ranged from 20 months to 55 years. Of 5 cases that documented patients' sex, 3 were males and 2 were females. Most (9/10) were asymptomatic; however, there was 1 inpatient case, concomitant with metastatic cholangiocarcinoma. Antiparasitic drugs were prescribed in 3 cases: niclosamide in 2 cases and praziquantel in 1 case. The 2 patients receiving niclosamide passed the parasites after treatment. CONCLUSION: In conclusion, the H diminuta infection is a rare cestode infection that is sporadically reported in Thailand. The diagnosis of H diminuta infection is usually by accident during a field survey. The prognosis outcome is usually good, and the treatment does not appear to affect outcome, as there is good survival without treatment.
