Data on the burden of visceral leishmaniasis (VL) in Indian sub-continent are vital for elimination programme planners for estimating resource requirements, effective implementation and monitoring of elimination programme. In Indian sub-continent, about 200 million population is at risk of VL. Nearly 25,000-40,000 cases and 200-300 deaths are reported every year, but these are grossly underesti...

BACKGROUND Post-kala-azar dermal leishmaniasis (PKDL) is a dermal complication of visceral leishmaniasis (VL), which may occur after or during treatment. It has been frequently reported from India and the Sudan, but its occurrence in South America has been rarely reported. It may mimic leprosy and its differentiation may be difficult, since both diseases may show hypo-pigmented macular lesions ...

background: visceral leishmaniasis (vl) has strong links with poverty, substantial medical and veterinary impacts. this review aimed to focus in studies published during 1994-2016 on vl in southeastern iran. methods : the present review is based on expert knowledge and historical studies published during the past 23 yr (1994-2016) on vl in southeastern iran. in addition, related literature foun...

The group of diseases known as the leishmaniases are caused by obligate intracellular protozoa of the genus Leishmania (39). Natural transmission of leishmania is carried out by a certain species of sandfly of the genus Phlebotomus (Old World) or Lutzomyia (New World). These are present in three different forms: (i) visceral leishmaniasis (VL), (ii) cutaneous leishmaniasis, and (iii) mucocutane...

Visceral leishmaniasis (VL), commonly known as kala-azar in Indian subcontinent is a major public health problem and >90% of cases are from India, Bangladesh, southern Sudan, Nepal and north-east Brazil. VL affects more than 1,00,000 persons every year in India and occurs epidemically and endemically in well-defined areas in the eastern parts of the country, mainly Bihar, West Bengal, the easte...

Between 2000 and 2010, Médecins Sans Frontières diagnosed and treated 4,831 patients with visceral leishmaniasis (VL) in the Pokot region straddling the border between Uganda and Kenya. A retrospective analysis of routinely collected clinical data showed no marked seasonal or annual fluctuations. Males between 5 and 14 years of age were the most affected group. Marked splenomegaly and anemia we...

Post kala-azar dermal leishmaniasis (PKDL) is a sequel of visceral leishmaniasis (VL) and PKDL patients are an important reservoir for anthroponotic transmission of VL. Therefore, diagnosis and treatment of PKDL is important for the kala-azar elimination program in South Asia, including Bangladesh. While definitive diagnosis of PKDL is still based on microscopy, despite the low sensitivity o...

Natural transmission of leishmaniasis is carried out by female sand flies. VL is a systemic disease characterised by prolonged fever, splenomegaly, hepatomegaly, weight loss, progressive anaemia, pancytopenia, and is complicated by serious infections. After recovery, some patients (50% in Sudan and 1 3% in India) develop post kala-azar dermal leishmaniasis (PKDL) characterised by depigmented ma...

We evaluated lymph node aspiration (LNA) as a simple diagnostic procedure for visceral leishmaniasis (VL). Lymph node aspiration was compared with the direct agglutination test (DAT) using a diagnostic titer > or = 1:6,400 in 7,880 suspected VL patients in eastern Sudan. Compared with DAT, LNA had a sensitivity of 65.1% (95% confidence interval = 63.5-66.6%). Parasite density in LNA correlated ...

Visceral leishmaniasis (VL) (kala-azar) was most seriously prevalent in the plain regions of eight provinces/municipalities in the eastern and central parts of China. In the early 1950s, the number of counties/cities endemic for VL and the number of cases in the plain regions accounted for 60% and 80%, respectively, of the total numbers in the entire country. By implementing comprehensive contr...
