Visceral leishmaniasis (VL) is a vector-borne disease caused by the obligate intracellular protozoan in India. VL can be complicated by post-kala-azar dermal leishmaniasis (PKDL), a macular or nodular rash that develops in 10%-20% of patients after treatment of VL in India. Patients with PKDL are infectious to sand flies, promoting further transmission of the parasite.

Background: The underlying pathophysiology of some occupational diseases such as silicosis involves autoantibodies. An autoantibody, antineutrophil cytoplasmic antibody (ANCA), has been recently reported and is known to be elevated in diseases such as vasculitis; therefore, the disease is currently known as ANCA-associated vasculitis. The risk of ANCA-associated vasculitis is known to be 25 times higher in patients with silicosis than in those without any occupational disease.

This review explores the therapeutic potential of the stable gastric pentadecapeptide BPC 157 in addressing electrolyte imbalances, specifically hyperkalemia, hypokalemia, hypermagnesemia, and hyperlithemia. In hyperkalemia, BPC 157 demonstrated a comprehensive counteractive effect against KCl overdose (intraperitoneally, intragastrically, and in vitro), effectively mitigating symptoms such as muscular weakness, hypertension, sphincter dysfunction, arrhythmias, and lethality. It also counteracted the adverse effects of succinylcholine and magnesium overdose, including systemic muscle paralysis, arrhythmias, and hyperkalemia.

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.

Chikungunya virus infection often manifests as an acute, self-limiting febrile illness, with arthralgia and musculoskeletal symptoms being the most commonly reported. Arthralgia can persist for months or even years, and approximately 50% of cases progress to chronic conditions. However, recent outbreaks have revealed a rising number of severe cases and fatalities.
