Utility of Blood as the Clinical Specimen for the Molecular Diagnosis of Post-Kala-Azar Dermal Leishmaniasis.

The countries in the Indian subcontinent have reported a dramatic decline in visceral leishmaniasis (VL) cases. However, the presence of the parasite reservoir in the form of post-kala-azar dermal leishmaniasis (PKDL), a dermal sequel of VL, is a hurdle in attaining VL elimination. Presently employed clinical specimens for the diagnosis of PKDL include skin biopsy specimens and slit skin smears.

Real-Time Fluorimetry Loop-Mediated Isothermal Amplification for Diagnosis of Leishmaniasis and as a Tool for Assessment of Cure for Post-Kala-Azar Dermal Leishmaniasis.

Despite the dwindling number of visceral leishmaniasis (VL) cases in India, there is an urgent need for early and unequivocal diagnostics for controlling and preventing the reemergence of VL. Post-kala-azar dermal leishmaniasis (PKDL), a dermal sequela of VL, serves as a reservoir of the parasite. Diagnosis of PKDL, especially the macular variant, is challenging and poses impediment toward attainment of VL elimination.

Advancement in Molecular Diagnosis of Post Kala-Azar Dermal Leishmaniasis.

Post kala-azar dermal leishmaniasis (PKDL), a clinical sequela of visceral leishmaniasis (VL), plays a critical role in the anthroponotic transmission of VL, particularly in the Indian subcontinent (ISC). The early, accurate, and feasible diagnosis of PKDL is essential for the attainment and sustenance of VL elimination goal in ISC. PKDL poses a stumbling block for this goal, considering the heterogeneity presented with regard to time after cure of VL and onset of PKDL, chronicity, and clinical variations.

Assessing the Efficacy and Safety of Liposomal Amphotericin B and Miltefosine in Combination for Treatment of Post Kala-Azar Dermal Leishmaniasis.

Background: No satisfactory canonical treatment is available for post-kala-azar dermal leishmaniasis (PKDL), clinical sequela of visceral leishmaniasis. Confined treatment options and substantial increase in relapse rate after miltefosine (MIL) treatment warrant the need to adapt resilient combination therapies. In this study, we assessed the safety and efficacy of combination therapy using liposomal amphotericin B (LAmB) and MIL for treating PKDL.

Validation of SYBR green I based closed tube loop mediated isothermal amplification (LAMP) assay and simplified direct-blood-lysis (DBL)-LAMP assay for diagnosis of visceral leishmaniasis (VL).

Background: The World Health Organization has targeted elimination of visceral leishmaniasis (VL) in the Indian subcontinent (ISC) by 2020. Despite distinctive decline seen in the number of VL cases in ISC, there is still a quest for development of a diagnostic test which has the utility for detection of active infection and relapse cases and as a test of cure. The present study validated the sensitivity and specificity of SYBR Green I based closed tube LAMP assay reported by us for diagnosis of VL.
