Parasite Burden of Trypanosoma cruzi in Whole Blood and Buffy Coat Determined by Real-Time PCR in Individuals with Chronic Chagas Disease

Role of buffy coat in detection of microfilaria in absence of eosinophilia: a case report

Filariasis is a very important public health problem endemic in tropical and subtropical countries. It is a debilitating disease with significant socioeconomic burden. In 2016, lymphatic filariasis was successfully eliminated from the Maldives, which was certified by WHO. We report a case of filariasis detected by a rapid antigen test while undergoing a screening program conducted by Health Protection Agency, Maldives in December 2023. The patient was asymptomatic and showed no peripheral blood eosinophilia. Conventional blood smears were negative. Nevertheless, buffy coat smear served as a promising test in detection of parasite, thus confirming the re-emergence of the disease in the country. Therefore, our study highlight the significance of buffy coat smears in detection of hemoparasites. We also focus on the importance of surveillance system in order to sustain the disease elimination goal that was already achieved.
