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.

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.

Visceral leishmaniasis (VL) caused by Leishmania donovani, a protozoan parasite, is a disease of high morbidity associated with hepatosplenomegaly, hypergammaglobulinemia, fever and death. One of the immunological hallmarks of VL is a remarkable increase in serum immunoglobulin levels as a result of polyclonal B cell activation. This study demonstrated that T lymphocytes expressing the T cell receptors (TcR) gamma delta in association with CD3 molecules are increased in circulation of patients with VL. A large proportions of TcR gamma delta-bearing T cells had CD4+ CD8- phenotype, and expressed CD25, CD38, CD71 and HLA-DR activation antigens. Furthermore, we demonstrated wide functional differences in TcR gamma delta and TcR alpha beta T cells in their proliferative response, secretion of interleukin-2 (IL-2), B cell growth factor (BCGF) and B cell differentiation factor (BCDF). It was of interest that the TcR gamma delta T cells from patients with VL could be expanded by in vitro culture with human recombinant IL-2. Although these TcR gamma delta T cells secreted diminished levels of IL-2, they produced highly augmented levels of both BCGF and BCDF, suggesting that secretion of these lymphokines in these T cell subsets is regulated independently. The relative increases in the CD4+ CDw29+ TcR gamma delta T cell subsets and their secretion of highly elevated levels of BCGF and BCDF largely accounted for the humoral immune system abnormality and hypergammaglobulinemia found in this disease. These observations may help to explain that TcR gamma delta T cells might be functional in vivo and are involved in immunological mechanisms of pathogenesis in VL.

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.

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.

In a young man who had a prolonged fever of unknown origin, hepatosplenomegaly, and progressive pancytopenia, stained smears, blood-agar cultures of bone marrow, and serologic testing for antileishmanial antibodies were negative. Biopsies from liver and bone marrow were uninformative. Visceral leishmaniasis was diagnosed only after splenectomy, when amastigotes were finally cultured from the spleen. The parasite was shown to be an unusual leishmanial parasite, possessing a mixture of intrinsic biochemical and serologic characteristics displayed independently by Leishmania tropica and Leishmania donovani sensu lato, the latter being the usual cause of visceral leishmaniasis. After splenectomy, parasites were also demonstrated in stained bone marrow aspirate smears. Recovery was uneventful after treatment with antimony for 28 days. Visceral leishmaniasis can be a cause of fever of unknown origin and should be considered in its differential diagnosis in endemic areas.

A 5 year old German girl contracted visceral leishmaniasis during a vacation in Spain, either 32 or 20 month prior to the manifestation of disease. She presented with fever, hepatosplenomegaly and pancytopenia. A bone marrow aspirate proved the diagnosis. Therapy with a pentavalent antimony drug brought about immediate improvement. Visceral leishmaniasis has to be suspected in individuals with fever, hepatosplenomegaly and pancytopenia who have resided in endemic areas (Mediterranean countries, India, East Africa, South America) during the previous years. If untreated, visceral leishmaniasis runs a fatal course. Therefore, early diagnosis by morphological and serological means and specific therapy with pentavalent antimony drugs are mandatory.

This study describes the plasma lipoprotein system of young children with visceral Leishmaniasis (Kala-azar disease). In addition to the presence of amastigote forms in the sternal aspirates of bone marrow, the patients exhibited fever, anemia, hepatosplenomegaly, various degrees of pancytopenia and a slight liver cytolysis. Patients had normal total cholesterol levels and increased triglyceride levels in the plasma. The concentrations of HDL and LDL were 30% and 50% of these reported for normolipemic subjects, respectively. In contrast, there was a three-fold increase in the concentration of VLDL. The ratio of free to total cholesterol was high; this was further substantiated by electron microscopy of HDL showing the presence of disc-like particles. Quantitative determination of apolipoproteins revealed a three- and seven-fold decrease of apolipoproteins (Apo) A-I and A-II, respectively, whereas Apo B levels were within the normal range. The presence of LP-A-II particles was demonstrated by two-dimensional immunoelectrophoresis in most of the patients' plasma during the acute phase of disease.

A 53-year-old man developed a septic fever up to 40 degrees C, pancytopenia and hepatosplenomegaly after a holiday in Spain. Administration of piperacillin and amikacin was ineffective, but the fever subsided and partial haematological remission occurred when 1 mg/kg methylprednisolone daily was added. After six months his general condition worsened and pancytopenia with typical inclusion bodies in bone-marrow macrophages was noted, leading to the diagnosis of visceral leishmaniasis (Kala-Azar). The diagnosis was confirmed by serological tests. The causative organism was eliminated and the abnormal findings regressed during treatment with sodium stibogluconate, at first 600 mg/d for two weeks, then 850 mg/d over 16 days, interrupted for 14 days because of side effects.
