Kala-azar (visceral leishmaniasis [VL]) is endemic in southern Iran. We retrospectively evaluated 367 infants and children suffering from VL at hospitals affiliated to the Shiraz University of Medical Sciences in Fars Province, southwest Iran). Seasonal variations were observed with more cases presenting in late winter, spring and fewer in summer. The predominant clinical features in these patients were chronic fever, pallor, weight loss, abdominal distention and hepatosplenomegaly. Lymphadenopathy was less common. Common laboratory abnormalities included anaemia, leukopenia, thrombocytopenia, hypoalbuminaemia and hypergammaglobulinaemia. Liver function tests were deranged in two-thirds of the patients. The immunofluorescence antibody test was positive in all patients and all of them had a positive bone marrow smear or a culture for Leishmania donovani. Patients responded well to glucantim therapy with a cure rate of 96.7%. Relapse was observed in 8.2% (30). Mortality in this series was 7.3%. Twenty patients died during their therapy period. Jaundice and grossly deranged liver function tests were found to be bad prognostic signs.

One hundred and one children with visceral leishmaniasis (VL) who admitted to Akdeniz University Hospital during a 20-year period were analyzed. Median age of the patients was 3 years (range: 5.5 months-13 years). The most common symptoms at presentation were fever, pallor and abdominal distension. Splenomegaly was found in all of the patients while hepatomegaly was present in 98%. Anemia (96%), leukopenia (74%) and thrombocytopenia (56%) were the main laboratory abnormalities. Thirty-three (33%) of the patients were pancytopenic on admission. Bone marrow smear was positive for leishmania in 91% of the patients. Seventy-four patients were treated with antimony +/- pentamidine and 27 with amphotericin B. Three of our patients died because of secondary infections and hemorrhage. Relapse was observed in two patients. No patient showed post kala-azar dermal leishmaniasis findings. We conclude that VL should be considered in patients with prolonged fever, hepatosplenomegaly and cytopenia who live in an endemic region. Amphotericin B is a therapeutic agent as effective as pentavalent antimony compounds and could be preferred.

An Eritrean-born man observed over an extended period had upper gastrointestinal symptoms, fever, hepatosplenomegaly and pancytopenia in the setting of advanced HIV infection and poor adherence to antiretroviral therapy. Despite thorough investigation, it was not until a repeat gastroscopic examination and gastric biopsy were performed 18 months after initial presentation that Leishmania infection was diagnosed. The species was identified by polymerase chain reaction assay as L. donovani. Physicians managing HIV-infected patients from regions where Leishmania is endemic should consider visceral leishmaniasis, even in patients who have not lived in a Leishmania-endemic region for many years.

Existing standard treatment options for visceral leishmaniasis are less than optimal. We report here the use of oral miltefosine in the treatment of two paediatric cases of visceral leishmaniasis at a tertiary care hospital in Karachi, Pakistan. One patient came from Balochistan while the second patient was from Northern Pakistan. Both presented with a prolonged history of fever, massive hepatosplenomegaly, anaemia and thrombocytopenia. Visceral leishmaniasis was diagnosed with bone marrow studies. Amphotericin B was first started in the first patient; however severe hypokalaemia and allergic reaction occurred. Oral miltefosine was then administered. The child showed clinical improvement with regards to signs of leishmania infection but succumbed to a nosocomial infection during the hospital stay. In the second patient, miltefosine was started in the first instance. He showed remarkable clinical improvement. At 2 months follow-up, the child showed adequate weight gain along with successful resolution of hepatosplenomegaly and fever. Miltefosine has the potential to be considered a first line therapy for visceral leishmaniasis in developing countries; however larger studies are warranted to validate the trends observed in this small case series.

Leishmaniasis is a zoonotic disease which may be difficult to diagnose in children. Successful results have been achieved with amphotericin B in treatment. Here, we present a 7 month old girl who lives in Istanbul. She was given a diagnosis of kala-azar and treated with liposomal amphotericin B. Our case, born in Istanbul, had had fatigue for 3 weeks and pallor and abdominal distention for 2 days. History of travel was absent. In physical examination, paleness, malaise and hepatosplenomegaly were found. In laboratory findings there was pancytopenia and her albumin level was low. A peripheric smear and other laboratory findings were normal. Her first bone marrow aspiration was normal. Because of persistent fever and increase in hepatosplenomegaly, a second bone marrow aspiration was done on the tenth day after admission and Leismania amastigotes were seen. She was given a diagnosis of kala-azar and, clinical and microbiological responses were achieved by treatment with amphotericin B. In our country, visceral leishmaniasis should be considered in all age groups who live in western regions and have no history of travel and contact, that present with pancytopenia or bicytopenia, even if massive splenomegaly is absent.

Sudanese visceral leishmaniasis (VL) is a disease of children that is characterized by fever, hepatosplenomegaly, lymphadenopathy, pancytopenia, and renal injury. Microalbuminuria (MA) and urinary retinol binding protein (urRBP) are useful markers for glomerular and tubular dysfunctions, respectively. We report the prevalence of subtle renal injury in 88 parasitologically confirmed VL patients in a cross-sectional and hospital-based study. Blood and urine were collected before treatment for hematological, biochemical profiles in addition to MA and urRBP measurement using competitive solid phase, sandwich enzyme-linked immune sorbent assay (ELISA), and immunoturbidometry. All the patients had normal serum urea and creatinine levels and no detectable urRBP. However, 40% of the patients had MA detected by ELISA, and 42% were reactive with turbidometry. The sensitivity, specificity, positive and negative predictive values for MA turbidometric technique were calculated as 100%; 96%; 95% and 100%, respectively. In conclusion; subtle renal injury in VL is mainly glomerular. Turbidometry for MA measurement is a simple, inexpensive, sensitive, and specific technique with high predictive values.

Visceral leishmaniasis is a severe and potentially fatal vector-borne disease. The most typical symptoms are fever, hepatosplenomegaly, weight loss, bleeding and bacterial infections. Neurological changes are rarely reported. This paper describes a child who presented with neurological signs as the first symptoms of leishmaniasis; tone was diminished and tremors in the extremities were observed. A diagnosis of visceral leishmaniasis was confirmed by parasite detection in the bone marrow. Symptoms were reversed by specific treatment. The nature of a possible mechanism of neurological involvement in visceral leishmaniasis remains unexplained.

Leishmania infantum is endemic in the Maltese archipelago, a group of islands in the Mediterranean which are visited frequently by tourists from Northern European countries. The burden of leishmaniasis is highest in children who may present with cutaneous or visceral manifestations. We describe systematically the manifestations, diagnosis and management of leishmaniasis in children <14 years of age, who had a histopathological diagnosis of leishmaniasis in Malta, from 2004 to 2008. Eleven children were diagnosed with leishmaniasis; 8 children (15-44 months of age) had visceral disease and three (aged 9-13 years) suffered cutaneous infections. Prolonged high grade fever, pallor, hepatosplenomegaly, and pancytopenia were common presenting features of visceralisation. Diagnosis was based on the visualisation of amastigotes from bone marrow aspirates. Pentavalent antimonials were associated with treatment failure in two children, whilst liposomal amphotericin B was curative in all. Children with cutaneous leishmaniasis had dry crusted ulcero-nodular lesions on exposed areas which responded to intra-lesional instillation of sodium stibogluconate or to cryotherapy. Leishmaniasis should be included in the differential diagnosis of fever and hepatosplenomegaly or chronic cutaneous lesions in children who travel to Malta.

The present study describes pathologic findings and immunohistochemical diagnosis of canine visceral leishmaniasis (CVL) in 22 dogs who died naturally in the Aegean region of Turkey. At necropsy, lymphadenomegaly, hepatosplenomegaly, hepatic, and nephrosclerotic lesions were conspicuous. Histopathologically, chronic inflammatory reactions of the spleen, lymph nodes, bone marrow, liver, and skin were marked findings. Cytological and histological examinations showed macrophages loaded with Leishmania amastigotes in these organs. Immunohistochemistry revealed that immunolabeling of amastigotes and/or parasite antigen, especially in the lymph nodes, spleen, bone marrow, liver, and skin, and occasionally, in the kidneys, intestines and lungs. Our laboratory results showed that immunohistochemistry should be included, along with cytological and histological examinations, in the diagnosis of CVL.

Malaria is endemic in Malaysia. Leishmaniasis is a protozoan infection rarely reported in Malaysia. Here, a 24-year-old Nepalese man who presented with prolonged fever and hepatosplenomegaly is reported. Blood film examination confirmed a Plasmodium vivax malaria infection. Despite being adequately treated for malaria, his fever persisted. Bone marrow examination showed presence of Leishman-Donovan complex. He was successfully treated with prolonged course of amphotericin B. The case highlights the importance of awareness among the treating physicians of this disease occurring in a foreign national from an endemic region when he presents with fever and hepatosplenomegaly. Coinfection with malaria can occur although it is rare. It can cause significant delay of the diagnosis of leishmaniasis.
