Leishmaniasis, a parasitic disease transmitted by the bite of some species of sandflies affects various age groups depending on the infecting Leishmania species, geographic location, disease reservoir, and host immunocompetence. Visceral leishmaniasis is the most severe form of the disease affecting children. The extent and presentation of the disease depend on several factors, including the humoral and cell-mediated immune response of the host, the virulence of the infecting species, and the parasite burden. Children are at greater risk than adults in endemic areas. Malnutrition contributes to the development of disease, and incomplete therapy of initial disease is a risk factor for recurrence of leishmaniasis. Children usually present with intermittent fever, paleness, refusal to feed or anorexia, weight loss, and abdominal distension. Splenomegaly, hepatomegaly, lymph node enlargement, thrombocytopaenia, anaemia, leukopaenia and hypergammaglobulinemia are the most common findings in Paediatric leishmaniasis. Molecular methods appear to offer the promise of accurate non-invasive tools for the diagnosis of Leishmaniasis. Till these methods are evaluated, definite diagnosis will rely on the demonstration of the infecting parasite in various tissues. World-wide, with the notable exception of India, pentavalent antimonial compounds remain the most effective and the most affordable therapy for this disease. Lipid formulations of amphotericin B were assessed as short duration treatment and were proved to be effective. However, their cost precludes their wide use in developing countries. Miltefosine, a new oral agent, might prove effective, safe, and affordable. Strategies aimed at control of the micro-population of sandflies, eradication of canine leishmaniasis, and offering personal protection against sandfly bites, together with health education programs in developing countries, can help control the disease. Development of an effective vaccine remains a priority.

The People's Republic of Bangladesh has been working to eliminate visceral leishmaniasis or Kala-azar cases since there was a memorandum of understanding signed between neighboring countries in 2005. As a part of the elimination activity, 44 cases of Kala-azar were diagnosed and treated in the regional referral center Dhaka Medical College Hospital (DMCH) during the last three years, which is reported here. Confirmed leishmaniasis cases were included. Patients attending this specialized center with different demographic characteristics and varied presentations with laboratory findings were reviewed and recorded in a structured case record form. Ethical clearance was obtained prior to starting the study. A total of 44 patients with leishmaniasis were reviewed. Approximately 89% (n = 39) were New Kala-azar (NKA), 7% (n = 3) were Relapse Kala-azar (Relapse KA), only one case (2%) was Kala-azar Treatment Failure (KATF) and Post Kala-azar Dermal Leishmaniasis (PKDL) for both. The mean age of presentation was 32 years. Forty percent of patients had houses made by mud, 26% by tin shed, and the rest lived in buildings and semi-buildings. The predominant clinical features were fever (90.9%), pallor (88.6%), splenomegaly (81.8%) and hepatomegaly (68.2%). rK39 was positive in 90.7% of cases, and 94.4% of cases were positive for LD bodies on splenic aspirate. Of all, 90.90% were treated with Inj. Liposomal amphotericin B and 9.10% with the combination of Inj. Liposomal Amphotericin B and Inj. Miltefosine. Moving forward to the elimination of leishmaniasis from Bangladesh, the study highlights the status, characteristics and treatment of the disease in the country.
