The article reports on a case of visceral leishmaniasis in a 3-year-old child of German residents in Rome who had passed two vacations on the isle of Ischia. Initial signs were intermittent temperatures, marked anorexia, hepatosplenomegaly and pancytopenia, with spontaneous recovery after three weeks. At that time, leishmania serology was already positive, whereas no leishmania were found in several bone marrow preparations despite a most thorough search. During the following eight weeks, the patient had chickenpox and mumps. During the mumps, relapse of the visceral leishmaniasis occurred, associated with a dramatic increase of the hepatosplenomegaly and recurring pancytopenia. It was only now that we could discover multiple leishmania infection of the bone marrow. Subsequent therapy with sodium stibogluconate (Pentostam) was effective without any complications, and eventually cured the patient.

A 19-year-old women developed prolonged fever, weight loss, hepatosplenomegaly, anemia, leukopenia, and hyperglobulinemia. Appropriate tests indicated that she had visceral leishmaniasis (kala-azar). Urinalysis demonstrated significant proteinuria and microhematuria with the presence of red cell casts. A kidney biopsy was performed. Light microscopy showed a slight mesangial thickening and segmental mesangial proliferation. Immunofluorescence demonstrated deposits of immunoglobulins A and M, complement, and fibrinogen. Electron microscopy showed subendothelial and intramembranous deposits. After treatment with N-methylglucamine antimonate the proteinuria and microhematuria disappeared and the patient recovered uneventfully.

The effect of administration of live Bacillus Calmette-Guerin (BCG), a nonspecific immunostimulant, on the course of experimental cutaneous leishmaniasis in mice was investigated. BALB/c mice were injected in the footpad with Leishmania tropica, NIH S-strain; in mice that were not pretreated with BCG this produced a reproducible fatal infection characterized by local inflammation, regional lymphadenopathy, and dissemination of parasites with hepatosplenomegaly. In mice that were pretreated with BCG and similarly infected with L. tropica there was a reduction in the severity of cutaneous disease and a significant (p less than 0.005) decrease in mortality without evidence of visceralization.

The epidemiology, clinicopathological features, and response to therapy of 63 Saudi patients with visceral leishmaniasis are described. The clinical features in our cases were similar to those described from Asir province, India, and Ethiopia, except for the presence of lymphadenopathy. Fever, hepatosplenomegaly, pancytopenia, and liver dysfunction were common findings. The unusual feature is the seasonal variation in the distribution of the disease. The response to sodium stibogluconate was excellent and the mortality rate was low (less than 1 per cent).

A 77-year-old man returned from Honan Province, mainland China, and developed intermittent fever and loss of body weight. On physical examination there was evidence of chest infection but no lymphadenopathy or hepatosplenomegaly. Laboratory data suggested anemia, thrombocytopenia and polyclonal gammopathy. The diagnosis of Leishmaniasis was finally established by bone marrow aspiration which disclosed Leishman-Donovan bodies. Unfortunately, the patient expired soon after the diagnosis was made and a partial autopsy was performed. Kala-azar is a rare disease in Taiwan. However, it should be suspected in those patients who have visited the endemic areas, even though the clinical manifestations are atypical.

Physicians examined the records of 47 adults with visceral leishmaniasis (VL) and HIV-1 infection who were patients at 3 urban teaching hospitals in the Andalucia region in southern Spain between January 1986 and November 1991. They wanted to identify the clinical, biological, and epidemiological features of VL in HIV-1 positive patients. 96% of the cases were diagnosed with both infections during the last 2 years of the study period and 79% between January and November 1991. All the patients had risk factors for HIV infection (65.9% IV drug use, 21.3% sexual contact, and 12.8% blood transfusion). 70% exhibited the classic symptoms of VL (fever, enlarged liver and spleen, and depressed counts of blood cells). Most patients were already very immunocompromised when VL was diagnosed. 87% had a total lymphocyte count of less than 1000 x 1 million/1 and a CD4 lymphocyte count of less than 200 x 1 million/1. In fact, 66% had full blown AIDS prior to diagnosis of VL. VL was the first severe infection in 10 cases. 68% also suffered from opportunistic infections, especially candidiasis, extrapulmonary tuberculosis, and Pneumocystis carinii pneumonia. Microscopic examination of Leishmania amastiogotes in tissue samples led to a diagnosis in 94% of cases, isolation of motile amastigotes in culture of bone marrow aspirate in 2%, and microscopic and culture in 4%. Just 46% completed a full course of treatment (pentavalent antimony, allopurinol, and/or pentamidine). Only 38% had a microbiological response. Immunofluorescence detected sizeable titers (1:40) of antileishmanial antibodies in just 31% of cases. 17% experienced clear clinical improvement. Physicians in endemic areas should consider VL in every HIV-1 infected patient with fever, hepatosplenomegaly, or hematological abnormalities to avoid underdiagnosis of leishmaniasis.

Visceral leishmaniasis is an important public health problem in Libya, but its exact prevalence is not known. Prompted by the paucity of information in the literature relevant to Libyan children, we reviewed the records of 21 children treated at El-Fatah Children's Hospital, Benghazi between March 1982 and May 1990. Visceral leishmaniasis was diagnosed on the basis of the history, physical findings and confirmatory laboratory tests including examination of bone marrow. The duration of illness before seeking medical advice ranged from 3 months to 1.5 years. The commonest presenting features were fever, abdominal distension, anorexia with weight loss, hepatosplenomegaly and pallor. The consistent laboratory findings were anaemia with reticulocytosis and normal serum iron, neutropenia, thrombocytopenia, high ESR and hyperglobulinaemia. The bone marrow was positive for L. donovani in 86% of cases and the indirect haemagglutination test was positive in all patients. Bronchopneumonia was the most common complication and responded rapidly to antibiotics. All patients were treated with sodium stibogluconate 10 mg/kg/day. There were no major side-effects or complications of drug therapy. The relative paucity of cases and their late presentation may reflect a lack of awareness of the occurrence of visceral leishmaniasis by doctors in the community.

Canine leishmaniasis, a generally fatal parasitic disease, was diagnosed in 2 dogs with a medical history of foreign travel, lymphadenopathy, emaciation, anorexia, intermittent fever, and cutaneous lesions. Clinically, hyperproteinemia, proteinuria, azotemia, and glomerulopathy were evident. Isolation of Leishmania species was done using Schneider's Drosophila medium. Syrian hamsters were used for infectivity studies. Clear taxonomic identification was done biochemically by isoenzyme analysis and comparison of zymogram banding patterns with 6 World Health Organization reference strains. Based on the geographic origin of affected dogs, clinicopathologic presentation, visceralization with hepatosplenomegaly in hamsters, and isoenzyme analysis, a diagnosis of Leishmania leishmania infantum was made. This study, representing the first taxonomic identification of an isolate from canine leishmaniasis, demonstrates the zoonotic and epidemiologic implications of this disease.

During an epidemic of visceral leishmaniasis in the Sudan, two cases of congenital kala-azar were seen. The first child, whose mother had contracted kala-azar in southern Sudan, was born in Khartoum, where no transmission of leishmaniasis is currently occurring. At seven months, the child had fever, lymphadenopathy, and hepatosplenomegaly; leishmania parasites were detected in the bone marrow. The child died and an autopsy showed leishmania parasites in all tissues including the lungs, kidneys, and thymus. In the second case, parasites were found in the placenta of a five-month-old fetus. These two cases demonstrate the importance of follow-up of infants born to mothers with leishmaniasis.

Parasitic infections and malnutrition coexist in many tropical and subtropical areas. Studies of Leishmania donovani and of experimentally infected Syrian hamsters have provided important insights into the complex interrelationships between malnutrition and this parasitic disease. Malnutrition, which adversely affects cell-mediated immunity, is associated with the development of visceral leishmaniasis (kala-azar) in children living in endemic areas. In turn, L. donovani can cause wasting as well as hepatosplenomegaly, fever, and anemia. Syrian hamsters infected with L. donovani develop a disease that is comparable to that of humans with kala-azar. Weight loss in infected hamsters is associated with splenic macrophage secretion of potentially catabolic cytokines as measured by the D10.G4.1 assay for interleukin-1 and the L929 cytotoxicity assay for tumor necrosis factor/cachectin. Although decreased food intake contributes to wasting in infected hamsters, studies of skeletal muscle function indicate that it is not the sole factor. Leishmania donovani-infected hamsters have also been used to study drugs with the potential to prevent or reverse cachexia.
