Kala azar is a disease endemic to the Sudan and a cause of major morbidity and mortality to affected patients when the diagnosis or treatment has been delayed. In this report we described the clinical features of 99 parasite proven patients with visceral leishmaniasis. The Sudanese kala azar patient is young in age (teens to 20's), has marked weight loss despite a continuous, excellent appetite and suffers from insomnia, epistaxis and abdominal pain. Hepatosplenomegaly is universally present. Generalized lymphadenopathy is a prominent feature (72%). The high prevalence of lymphadenopathy has a wide range of implications: for diagnosis, i.e., the use of lymph node aspiration; for response to treatment, i.e., the resolution of lymphadenopathy; and for studies of immunoregulation in this systemic infection.

We describe five cases of gastrointestinal leishmaniasis in patients with human immunodeficiency virus infection and review 10 additional cases reported in the literature. All of the patients had CD4+ cell counts of < 200/mm3, and AIDS had been previously diagnosed for 12 patients. Fever and splenomegaly were present in 46% of cases. Thirteen patients had digestive symptoms; these symptoms included diarrhea (6), dysphagia and/or odynophagia (6), abdominal pain (2), epigastric pain (2), gastrointestinal hemorrhage (1), and rectal discomfort (1). The regions of the digestive tract most frequently affected by Leishmania organisms were the duodenal mucosa (90%) and the gastric mucosa (75%). Endoscopy showed normal-appearing mucosa in 45% of cases. In 10 cases the diagnosis of visceral leishmaniasis was first made by biopsy of the gastrointestinal mucosa. In most cases treatment with antimonial agents was not effective.

A dog being treated with meglumine antimonate for leishmaniasis was examined because of anorexia, vomiting, diarrhea, weakness, and signs of abdominal discomfort. The history, physical examination findings, clinicopathologic abnormalities, and results of coagulation testing were compatible with a diagnosis of renal failure and disseminated intravascular coagulation. The signs of abdominal pain were most likely a result of microcirculatory obstruction. The cause of disseminated intravascular coagulation in this dog was not determined; however, visceral leishmaniasis could have been associated.

Gastrointestinal involvement is reported in approximately 50% to 93% of patients with human immunodeficiency virus. It is frequently the result of coinfection with several microorganisms. Selective Leishmania intestinal involvement presents with atypical symptoms for visceral leishmaniasis, and may appear as a relapse or as the first manifestation of the disease. The authors present a patient with acquired immune deficiency syndrome who has a history of treated leishmaniasis and gastrointestinal infection by showed Mycobacterium avium intracellulare (MAI). After the new onset of abdominal pain, an intestinal biopsy showed the presence of both MAI and Leishmania in duodenum. Intestinal infection by Leishmania must be included in the differential diagnosis in patients with a previous history of leishmaniasis or travel to an endemic area.

We report a case of coinfection of visceral leishmaniasis and Mycobacterium avium-intracellulare in the same lesions in the small bowel and bone marrow of a 33-year-old man with acquired immunodeficiency syndrome who complained of abdominal pain and chronic diarrhea. The duodenal mucosa and bone marrow biopsy specimens showed numerous foamy macrophages packed with two forms of microorganisms that were identified histologically and ultrastructurally as Leishmania and Mycobacterium species. Visceral leishmaniasis is rarely suspected in patients residing in nonendemic countries including the United States. It should be included in the differential diagnosis for opportunistic infection in patients with acquired immunodeficiency syndrome. An appropriate travel history is important. To our knowledge, this is the first reported case showing coinfection of visceral leishmaniasis and Mycobacterium avium-intracelluulare in the same lesion in a patient with acquired immunodeficiency syndrome.

Efficacy and safety of meglumine antimoniate and sodium stibogluconate BP 88R were compared in cutaneous leishmaniasis treatment in Corte de Pedra, Bahia, an endemic area of leishmaniasis due to Leishmania (Viannia) braziliensis. An open trial was developed with one hundred twenty seven patients who were diagnosed based on clinical criteria and Montenegro's skin test. Fifty eight patients were treated with meglumine antimoniate and 69 received sodium stibogluconate. Both groups received 20 mg/Sbv/kg/day for 20 days. Patients were followed every ten days during treatment and every month thereafter for three months. Sixty two percent patients cured with meglumine antimoniate and 55% cured with sodium stibogluconate (p = 0.42). Headache was more frequent during the first half of treatment in patients receiving sodium stibogluconate (p = 0.026). During the second half, patients treated with sodium stibogluconate showed a greater frequency of myalgia/arthralgia (p = 0.004) and abdominal pain/anorexia (p = 0.004). Three patients treated with sodium stibogluconate had severe side effects.

In this article, we report the case of a 16-month-old German boy who was admitted to the Children's Hospital of Stuttgart with a 4-week history of intermittent fever, decreased appetite, weakness, fatigue, and difficulty sleeping. He was healthy at birth and remained so for the first 15 months of his life. On admission, physical examination showed enlarged cervical, axillary, and inguinal lymph nodes, as well as hepatosplenomegaly. Laboratory data revealed pancytopenia, elevated liver function tests, and hypergammaglobulinemia. Blood, stool, and urine culture results were negative. Viral infections and rheumatologic and autoimmune disorders were ruled out, but a positive titer for Leishmania antibodies was noted. In a liver and bone marrow biopsy, the amastigote form of the parasite could not be seen in cells. The promastigote form of Leishmania was found and the diagnosis of visceral leishmaniasis was made by combining the cultures of both the liver and the bone marrow biopsy material in 5 mL 0.9% saline on brain heart infusion agar, supplemented with defibrinated rabbit blood and incubated at 25 to 26 degrees C for 5 days. The parasite was identified by Southern blot analysis as Leishmania infantum. Specific therapy with the antimonial compound sodium stibogluconate with a dose of 20 mg/kg body weight was begun immediately. Within 4 days, the patient became afebrile. The side effects of treatment, including erosive gastritis, cholelithiasis, worsening hepatosplenomegaly, elevation of liver enzymes, pancreatitis, and electrocardiogram abnormalities, necessitated the discontinuation of treatment after 17 days. On discharge 4 weeks later, the patient was stabilized and afebrile with a normal spleen, normal complete blood count, normal gammaglobulins, and decreasing antibody titers to Leishmania. During the next 24 months, the patient experienced intermittent episodes of abdominal pain, decreased appetite, recurrent arthralgia, and myalgia. But at his last examination in January 1998, he was well; all symptoms mentioned above had disappeared. Because the child had never left Germany, nonvector transmission was suspected and household contacts were examined. His mother was the only one who had a positive antibody titer against Leishmania donovani complex. She had traveled several times to endemic Mediterranean areas (Portugal, Malta, and Corse) before giving birth to the boy. But she had never been symptomatic for visceral leishmaniasis. Her bone marrow, spleen, and liver biopsy results were within normal limits. Culture results and polymerase chain reaction of this material were negative. A Montenegro skin test result was positive, indicating a previous infection with Leishmania. Western blot analysis showed specific recognition by maternal antibodies of antigens of Leishmania cultured from the boy's tissue. Visceral leishmaniasis is endemic to several tropical and subtropical countries, but also to the Mediterranean region. It is transmitted by the sand fly (Phlebotomus, Lutzomyia). Occasional nonvector transmissions also have been reported through blood transfusions, sexual intercourse, organ transplants, excrements of dogs, and sporadically outside endemic areas. Only 8 cases of congenital acquired disease have been described before 1995, when our case occurred. In our patient, additional evaluation showed that the asymptomatic mother must have had a subclinical infection with Leishmania that was reactivated by pregnancy, and then congenitally transmitted to the child. Visceral leishmaniasis has to be considered in children with fever, pancytopenia, and splenomegaly, even if the child has not been to an endemic area and even if there is no evidence of the disease in his environment, because leishmaniasis can be transmitted congenitally from an asymptomatic mother to her child.

Acute acalculous cholecystitis (ACC) is unusual. We present a case of cholecystitis associated with visceral leishmaniasis (VL) in a man in Venezuela who presented high fever, anorexia and abdominal pain. Histopathological study of the gallbladder showed Leishmania spp. ACC in VL must be kept in mind in tropical countries.

The authors report the occurrence of a fatal case in patient with cutaneous leishmaniasis in the municipality of Caxias, MA. Male patient, 22 years old, road sweeper, presented with an ulcer in left leg, diagnosed as cutaneous leishmaniasis and treated with sodium stibogluconate BP88 (Sb+5) (Shandong Xinhua) at a dose of 10mg/Sb+5/kg/day/20 days. After dose three he presented arthralgia, myalgia, nausea and weakness. During the therapy there was an aggravation of the symptoms with abdominal pain and irradiation into the thorax. After dose seven he presented a picture of associated dyspnea and thoracic pain of mild intensity. At dose nine there was further worsening of the picture, nevertheless the therapy was continued up to dose 11, when the patient's state deteriorated to such an extent that he was hospitalized in the intensive care unit. Exams: erythrocytes, 4.4 million; hemoglobin, 10.6%; hematocrits, 35%; white blood cells 26,400, basophiles and myelocytes (0); segmented leukocytes, 59%; lymphocytes 30%; monocytes 2%; platelets (normal); glucose, 42mg%; urea, 73mg%; creatinine, 2.4mg%; and ECG (blockade of right branch). The patient died from cardiorespiratory insufficiency. The current report underscores the need to clarify health workers regarding the use of Sb+5 and also to remind the Health Ministry to verify the quality and origin when acquiring new products.

We here report a case of subacute Budd-Chiari syndrome (BCS) related to Factor V Leiden (FVL) mutation in the presence of visceral leishmaniasis. A 17-year-old man was admitted to hospital because of abdominal pain, pretibial edema and fever. The clinical picture of BCS had been developed within several months. BCS was diagnosed by radiographic examination. On DNA analysis, a heterozygote Arg506Gln mutation in the factor V gene was found. Histological examination of the bone marrow showed intracellular leishmania amastigotes. Despite appropriate treatment patient's clinical condition deteriorated rapidly and died with multiorgan failure. FVL mutation is the most common procoagulant disorder and account for many cases of BCS. This case report demonstrates that in addition to duration and severity of the disease accompanying conditions including infections are prognostically significant for the outcome of this potentially lethal disease.
