Non-compaction cardiomyopathy and visceral leishmaniasis: uncommon combination with therapeutic challenges in a resource limited-setting.
Sudan J Paediatr

Pediatric Department, Faculty of Medicine, National University, Khartoum, Sudan.
Non-compaction cardiomyopathy (NCCM) or spongy myocardium is a rare type of congenital cardiomyopathy. Visceral leishmaniasis is a protozoal disease caused by and transmitted by the bite of female sand-fly species of , which is common in tropical areas like Sudan. We report a 6-year-old female, presented with a fever of unknown origin, weight loss, anemia that necessitated multiple blood transfusions and had hepatosplenomegaly.

Visceral leishmaniasis is a systemic disease that affects various internal organs and represents the most severe and fatal form of leishmaniasis. Conventional treatment presents significant challenges, such as prolonged management in hospital settings, high toxicity, and an increasing growing number of cases of resistance. In previous studies, our research group demonstrated the effective and selective activity of the 2-amino-thiophene derivative SB-83 in preclinical models of cutaneous leishmaniasis.

SET proteins are lysine methyltransferases. In investigating Leishmania donovani SET29, we found depletion of LdSET29 by two-thirds did not affect promastigote growth, nor alter the parasite's response to UV-induced or HU-induced stress, but made it more tolerant to HO-induced oxidizing environment. The deviant response to oxidative stress was coupled to lowered accumulation of reactive oxygen species, which was linked to enhanced scavenging activity.

The current treatment of leishmaniasis is confronted with significant challenges, including limited efficacy, adverse effects, and parasite resistance to drugs. The search for alternative therapeutic options, including the utilisation of natural products, has demonstrated considerable promise. In this study, the antileishmanial activity of the flavonoid hesperetin against Leishmania donovani, the causative agent of visceral leishmaniasis, was reported for the first time.

Background: Visceral leishmaniasis is endemic in Ethiopia and caused by Leishmania donovani. Although the disease manifests with significant clinical variability, a substantial number of individuals are asymptomatic. These individuals can serve as reservoirs, complicating control efforts.
