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.

Four weeks after returning from a holiday on Ischia, a 53-year-old man fell ill with nocturnal sweating, fever, severe general malaise and hepatosplenomegaly. Sternal marrow and liver punctures revealed an infection with Leishmania donovani, i.e. Kala-Azar. Characteristic features were hyperplasia of the plasma cells in the bone marrow and liver, together with lymphoplasmocytoid cell wash-out and polyclonal IgG proteinaemia. Treatment with pentamidine (Lomidine) was unsatisfactory, while all manifestations of the disease regressed after two courses of sodium stibogluconate (Pentostam), although the hypergammaglobulinaemia and hyperproteinaemia disappeared only slowly. The plasma-cell hyperplasia in conjunction with the hypergammaglobulinaemia, which suggest multiple myeloma, is interpreted as a result of antibody formation by the chronic parasitic infection. Together with storage-cell hyperplasia it is also taken to be the cause of the peripheral leukopenia and thrombocytopenia.

This is a case report of kala-azar with cutaneous leishmaniasis. Upon admission, the patient had fever, hepatosplenomegaly and an ulcer on her cheek. The patient responded to Pentostam. Isoenzyme studies of parasite isolates from the bone marrow and from the cutaneous lesion revealed that these were L. donovani and L. major, respectively. This is the first report in Iraq of a proven concomitant infection with two species of leishmania parasites.

Visceral leishmaniasis is endemic in southern Saudi Arabia. We prospectively evaluated 121 patients with visceral leishmaniasis at King Fahad Hospital in Gizan. All patients were infants and children. Seasonal variation was observed with more cases presenting in late spring and summer and few in winter. The predominant clinical features in these patients were chronic fever, abdominal distention, weight loss and hepatosplenomegaly. Lymphadenopathy was rare in contrast to African kala-azar. Common laboratory abnormalities included anemia, leukopenia, thrombocytopenia, hypoalbuminemia and hypergammaglobulinemia. Liver function tests were deranged in one-third of patients. Leishmania hemagglutination test was positive in all patients and all of them had positive bone marrow smear or culture for Leishmania donovani. Patients responded well to stibogluconate (Pentostam) therapy with a cure rate of 96.7%. Four patients died in the first few days of therapy. Jaundice and grossly deranged liver function tests were found to be bad prognostic signs.

The kingdom of Saudi Arabia (KSA) has succeeded in bringing the reported numbers of Visceral leishmaniasis (VL) cases from hundreds during the 1980s and 1990s to zero case in 2019. The endemicity of VL has been confined mainly to the Southwest regions, namely Jazan and Aseer regions. Leishmania donovani species have been identified as the causative species of VL, while L. infantum have been isolated only from dogs in the endemic areas. Many species of sand flies were caught in Southwest, but P. orientalis is the probable transmitter of the disease. The black rat (Rattus ratus) was found to be contributing to maintenance of the parasite life cycle. VL is primarily a disease of children, and 80% of cases were Saudi's, while cases from Yeminis nationality represent the majority of non- Saudi patients. The common clinical presentation consist of chronic fever, abdominal distention, weight loss, anemia and hepatosplenomegaly. Laboratory findings include: anemia, leukopenia, thrombocytopenia, hypoalbuminemia, hyperproteinaemia and hypergammaglobulinemia, low serum iron, and abnormal liver enzymes. Occurrence of jaundice has been identified as a bad prognostic sign. Diagnosis relying on direct smears from bone marrow aspirates was the commonest tool used, and also is advocated by the National Leishmaniasis Control Program (NLCP). Sodium stibogluconate (SSG) is the main drug used to treat VL cases, while Ambisome is preserved for complicated cases. Chemical control of sand flies using indoor residual spraying (IRS) with synthetic pyrethroids has been the most effective measure applied to prevent vector-human contact and disease transmission. The geographical overlap of VL and Malaria has facilitated the adoption and implementation of integrated vector control strategies. After reaching a zero case in 2019, the Ministry of Health (MoH) has a new commitment and facing a great challenge which are maintenance of current situation and elimination of VL. Through the support of stakeholders, encouragement of community participation, preparedness and readiness of leishmaniasis personnel, the new mission of the NLCP now is elimination of the scourge of VL from the country.
