Dahal P, Singh-Phulgenda S, Wilson J, Cota G, Ritmeijer K, Musa A, Alves F, Stepniewska K, Guerin PJ. Blood transfusion in the care of patients with visceral leishmaniasis: a review of practices in therapeutic efficacy studies. Trans R Soc Trop Med Hyg 2024; 118:481-490. [PMID: 38690667 PMCID: PMC11299541 DOI: 10.1093/trstmh/trae018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Revised: 01/04/2024] [Accepted: 03/27/2024] [Indexed: 05/02/2024] Open
Abstract
Blood transfusion remains an important aspect of patient management in visceral leishmaniasis (VL). However, transfusion triggers considered are poorly understood. This review summarises the transfusion practices adopted in VL efficacy studies using the Infectious Diseases Data Observatory VL clinical trials library. Of the 160 studies (1980-2021) indexed in the IDDO VL library, description of blood transfusion was presented in 16 (10.0%) (n=3459 patients) studies. Transfusion was initiated solely based on haemoglobin (Hb) measurement in nine studies, combining Hb measurement with an additional condition (epistaxis/poor health/clinical instability) in three studies and the criteria was not mentioned in four studies. The Hb threshold range for triggering transfusion was 3-8 g/dL. The number of patients receiving transfusion was explicitly reported in 10 studies (2421 patients enrolled, 217 underwent transfusion). The median proportion of patients who received transfusion in a study was 8.0% (Interquartile range: 4.7% to 47.2%; range: 0-100%; n=10 studies). Of the 217 patients requiring transfusion, 58 occurred before VL treatment initiation, 46 during the treatment/follow-up phase and the time was not mentioned in 113. This review describes the variation in clinical practice and is an important initial step in policy/guideline development, where both the patient's Hb concentration and clinical status must be considered.

Abstract
Background Visceral leishmaniasis (Kala-azar) is an inherently dangerous and progressive disease that can be seen in many parts of the world, including Iran. Therefore, we decided to conduct this study on children with Kala-azar in Rasht-Iran. Methods In this descriptive study, the hospital records of all children with Kala-azar disease admitted to 17 Shahrivar Hospital, Rasht-Iran from 2009 to 2021 were reviewed. Required information were collected from patients' records and descriptive statistical analysis was done using SPSS version 24 statistical software. Results A total of 22 children with visceral leishmaniasis were admitted to 17 Shahrivar Hospital during the study period. The average age of the children was 2.93 ± 3.32 years. Most of them (59.1%) were boys and lived in the foothills (59.1%). The most common season for children to get the disease was spring (45.5%), and the average duration of the disease until hospitalization was 16.5 ± 13.54 days. In this study, the most common clinical manifestations included fever (90.9%), splenomegaly (77.3%), hepatomegaly (50%), weakness and restlessness (27.3%), and vomiting (18.2%). The most common laboratory findings were anemia (90.9%), leukopenia (59.1%), increased erythrocyte sedimentation rate (ESR) (75%), and increased C-reactive protein (CRP) (75%). 72.7% of the children were treated with liposomal amphotericin and others with glucantime, which were all successful. Conclusion The results of our studies were consistent with most studies in Iran and other countries. These findings can help in the diagnosis and management of children with Kalaazar and better control of the disease in the province.

Abstract
BACKGROUND Visceral leishmaniasis (VL) type in Syria is Lashmania infantum, a fatal incapacitating disease, which is mostly seen in infants. SUBJECTS AND METHODS Hospital records of 19 children with VL were retrospectively reviewed. The period of the study was from June 2016 to July 2019. RESULTS The median age of the patients was 45.5 months. None was coinfected with human immunodeficiency virus or known to be immunocompromised. Pallor and anemia were observed in all cases, fever in 13 (68.42%), splenomegaly in 18 (94.7%), hepatomegaly in 11 (57.9%), thrombocytopenia in 15 (78.95%), and leukopenia in nine (47.4%). A bone marrow aspirate was obtained and Leishmania amastigotes were detected in all patients. All patients were initially treated with meglumine antimonate; one child did not respond and was treated with lipid formulations of amphotericin B. CONCLUSIONS Presentation of VL in the pediatric age group is characterized by pallor, fever, splenomegaly, and hepatomegaly. Hematological and biochemical indices are typical with cytopenias. In all cases, microscopic examination provided a positive diagnosis. Despite recent reports on decreased responses to antimonial drugs of patients with Mediterranean VL, meglumine antimonate treatment appears to be still highly effective in Syria.

Abstract
As an experienced writer, one is often asked the question "what can I publish" by younger and inexperienced colleagues who must publish. This paper will briefly review the reasons why academics publish and will then outline what kind of papers one may be able to publish with relative ease, using personal experience and citing first hand material as a practical guide. Potential authors must cultivate "a lean and hungry look" as competition from fellow writers is stiff, and editors are choosy. However, do take heart - if we, older colleagues did and can, you can too.

Abstract
BACKGROUND Visceral leishmaniasis (VL) remains a public health issue in Greece. The aim of this study was to describe the clinical and epidemiologic characteristics of pediatric VL in our region as well as to evaluate the laboratory findings and the diagnostic techniques that are applied. METHODS We retrospectively reviewed the medical records of all children diagnosed with VL in an 11-year period at a tertiary public hospital in the region of Athens. Demographic features, clinical information and laboratory findings were accessed. RESULTS A total of 43 cases were recorded during 2005-2015. Median age of the patients was 3.7 years. Pallor (100%), fever (98%), hepatosplenomegaly (55.8%) and appetite loss (32.6%) were the most common presentations of the disease. The predominant laboratory abnormalities were anemia (100%), thrombocytopenia (90.7%), elevated inflammatory markers (86.1%) and decreased albumin/globulin (A/G) ratio (72.1%). Four patients developed secondary hemophagocytic lymphohistiocytosis syndrome, whereas in 3 others abdominal ultrasound showed splenic nodules. Bone marrow aspiration detected Leishmania parasites in 92.7% of cases and the rapid rK39 strip test indicated anti-Leishmania antibodies in 97.1% of children. In addition, all patients in whom indirect immunofluorescent antibody test was implemented had positive results. CONCLUSIONS VL still affects children in our area. Fever, splenomegaly, anemia and appetite loss are the typical findings in children. Noninvasive techniques (immunofluorescent antibody test, rK39) in combination with bone marrow microscopy are useful in the diagnosis of pediatric VL.

Abstract
BACKGROUND Visceral leishmaniasis (VL) is a life-threatening parasitic infection transmitted by phlebotomine sandflies. We undertook this study to analyze the clinical features of pediatric VL in a population of Chinese children. METHODS A retrospective study was performed with pediatric patients (≤14 years) diagnosed with VL based on bone marrow biopsy, serology and diagnosis based on clinical manifestation and the improvement after the experimental drug when negative bone marrow and serology results were shown in West China Second Hospital, between January 2001 and December 2015. RESULTS A total of 43 patients were determined as having a VL infection (ranging from 4 months to 12 years with a slight male preponderance). Sixty-seven percent were less than 5 years of age and 74% of patients resided in endemic regions. The average time to diagnosis from the onset of symptoms was 37.5 days (ranging from 5 days to 6 months). The main clinical manifestations were fever (98%), splenomegaly (98%), hepatomegaly (74%), pancytopenia (72%), pallor (33%), cough (33%) and lymphadenopathy (33%). Hepatic dysfunction was also found in 24 patients (68%). All patients were treated with meglumine antimonite; only 1 child was treated with liposomal amphotericin B after resistance to meglumine antimonite was discovered. Patients were clinically cured except for 1 patient, who died from hemorrhagic shock because of refusal of standard treatment. CONCLUSIONS Although there were no specific clinical manifestations of pediatric VL, a characterization of the overall symptoms may lead to an improved awareness of VL by clinicians and prompt early diagnosis and treatments. Presently, pentavalent antimony remains the first-line drug and there is low resistance in China.

Abstract
Anemia is a typical symptom during visceral leishmaniasis (VL). We performed a systematic analysis of the literature on anemia in VL to understand the prevalence, severity, and possible mechanisms. Anemia is very common in VL patients with an overall prevalence higher than 90 %. The degree of anemia in VL is moderate to severe (hemoglobin level ∼7.5 g/dl), and the status can be recovered by treatment with antileishmanial drugs within a certain period of time. Possible pathogeneses of anemia in VL based on clinical observations included anti-RBC antibodies, dysfunction in erythropoiesis, and hemophagocytosis in the bone marrow or spleen, while hemolysis is a more likely cause than dyserythropoiesis. In hamsters with experimental VL, hemophagocytosis induced by immune complex and changes on erythrocyte membrane is speculated as the pathogenesis for anemia. In contrast, our recent study on murine VL indicated that hemophagocytosis contributes to anemia in contrast to lower contribution of anti-RBC antibodies or dysfunction in erythropoiesis. Together, hemophagocytosis is most likely associated with anemia in VL, and elucidation of the immunological mechanisms may lead to development of novel interventions to manage the symptom.

Abstract
Leishmaniasis is one of the major health problems in Iran. Although the incidence of visceral leishmaniasis (VL) is reported almost everywhere, the northwestern Iran is one of the major endemic regions.To do this study, clinical, laboratory as well as disease characteristics of children admitted to Children Cure and Health Hospital, Tabriz University of Medical Sciences, were examined as the reference hospital for the treatment of VL in northwestern Iran.In this study, 156 children hospitalized in a pediatric hospital from 2000 to 2015 for VL were included. Gender, age, anemia, thrombocytopenia, increase in the erythrocyte sedimentation rate (ESR), alanine transaminase (SGPT), and aspartate transaminase (SGOT), major clinical manifestations such as fever, splenomegaly, hepatomegaly, treatment type, and the disease were studied.Among 156 patients examined in this study, 88 (56.41%) and 68 (43.59%) participants were male and female, respectively. The minimum and maximum ages of the infection were 4.5 months and 6 years, respectively. The mean age of the infected children was 17.94 months. Fever (94.24%) and splenomegaly (86.53%) were the most common symptoms of this disease among children. In addition, 49 (31.41%), 64 (41.02%), 18 (11.53%), 33 (21.15%), and 40 (25.64%) participants had leukopenia, hemoglobin count below 8, ESR above 100, ESR above 60, and platelets below 100,000, respectively. Moreover, 39 (25%) and 17 (10.89%) patients had high aspartate transaminase (AST) and alanine transaminase (ALT). Also, 96.2% of the participants responded to the treatment with glucantime. The rate of mortality in this study was 3.2%.Clinically, almost all children had fever and splenomegaly at the onset of the disease. In addition, hepatic involvement was observed in all cases of mortality, cases with a lack of initial response, and those in need of auxiliary medication. Hepatic involvement appears to be related to the prognosis of the disease. In our study, bone marrow aspiration (BMA) and positive direct antiglobulin test (DAT) were observed in 66.67% and more than 90% of the patients, respectively.Children with VL in northwestern Iran responded well to glucantime. In case of resistance, amphotericin B was a good alternative. Early diagnosis is essential in reducing mortality rate.

Abstract
Leishmaniasis is a parasitic disease with clinical presentations that vary from asymptomatic infection to cutaneous, mucocutaneous or visceral disease. Recent epidemiological studies have shown an increased prevalence in Europe largely caused by an increase in international travel, difficulty eradicating leishmanial infection in AIDS patients, and the use of immunosuppressive medications. Clinical diagnosis may be challenging, and parasitological diagnosis entails the use of invasive procedures which may be unrevealing in the immunosuppressed. A number of less invasive tests for the detection of anti-leishmanial antibodies or leishmanial antigen are available but their sensitivity and specificity may vary with the infective species and results have to be interpreted in light of the clinical presentation. The availability of polymerase chain reaction assays amplifying leishmanial genetic material has been a major step forward in improving the diagnosis of leishmanial disease and the response to treatment.

Abstract
OBJECTIVE Visceral leishmaniasis (VL) in north-west Ethiopia is causing an overwhelming case load among adult migrant workers that masked the disease burden in children. This study describes the clinical profile and explores comorbidities in paediatric VL patients. METHODS A prospective study at two hospitals in this region (Gondar and Humera) was conducted in a year period, 2011-2012. The clinical manifestations and comorbidities such as malnutrition, intestinal parasitosis and vitamin D deficiency and HIV infection were assessed, and treatment outcomes noted. RESULTS A total of 122 children with VL were detected during the study period with median age of 8.5 years (IQR 5-12 years); 23% were under 5 years. Eighty-five (69.7%) cases were male. The clinical manifestations were similar to the adult patients. High rates of malnutrition, intestinal parasitosis (47.5%) and hypovitaminosis D (56.4%) were detected. The proportion of stunting and wasting was 63% and 22.2% in children aged under five years, and 50.5% and 75.9% in 5-year and older children, respectively, using WHO standard growth curves. Only one child had HIV infection. In 95% of the cases, sodium stibogluconate (20 mg/kg/day for 30 days) was used for treatment. The treatment success rate at end of therapy was 98.3%, but the definitive outcome at 6 months could not be determined because of a high loss to follow-up (80.2%). CONCLUSION While HIV co-infection was rare, malnutrition, intestinal parasitosis and vitamin D deficiency were frequent indicating the need for further research on their role in the pathophysiology. Meanwhile, systematic assessment and management of malnutrition and intestinal parasitosis in VL programmes is recommended.

Abstract
Leishmaniasis remains an important neglected tropical infection that affects children more than adults. Geographical variation exists in the distribution of the various Leishmania species. Although the majority of the disease burden is found in poor countries, leishmaniasis is also endemic in several countries within Southern Europe. Transmission is mediated by the sandfly and may follow an anthroponotic or zoonotic cycle that also varies by region. The expression of leishmaniasis depends on a complex interaction between the type of infecting species and the host immune response. Infection may be asymptomatic or may manifest as cutaneous disease that is pleiomorphic in presentation, muco-cutaneous disease or the visceral form that may be lethal if untreated. Molecular techniques aid diagnosis especially in cases where amastigotes are not visualised. The efficacy of treatment varies with the type of infecting species and resistance patterns. Preventive measures aimed at avoiding sandfly bites are effective in reducing acquisition of leishmaniasis and should be promoted for travellers visiting endemic regions. The persistent lack of a vaccine against human leishmaniasis is a result of the poor investment in this neglected parasitosis.

Abstract
BACKGROUND Visceral leishmaniasis (VL, kala-azar) is caused by Leishmania spp, a parasite that is commonly encountered in Mediterranean countries. Leishmaniasis usually presents with fever, hepatosplenomegaly, lymphadenopathy, and pancytopenia. OBJECTIVES The aim of the study was to prospectively examine the characteristics of cytopenia associated with VL and compare it with other post-infectious cytopenias observed in children with febrile illnesses. METHODS We studied 112 children, aged (mean) 4.0 (SD, 3.8) years (range, 0-14 years), who were admitted to the pediatric ward because of febrile cytopenia associated with infections, during a 2-year period (March 2005 to June 2007). Study participants were investigated with measurement of acute-phase reactants, bacterial cultures, and serologic tests. RESULTS Pancytopenia was detected in 9 (8%) of 112 patients (5 boys), with a mean age of 4.5 (SD, 3.0) years.The mean value of white blood cell was 3827 (SD, 1455)/mL; absolute neutrophil count, 1229 (SD, 655)/mL; hemoglobin, 8.3 (SD, 1.1) g/dL; and platelet count, 88,200 (SD, 20,186)/mL. All patients with pancytopenia had fever (mean duration, 8.9 [SD, 8.7] days) (maximum temperature, 39.5°C [SD, 0.6°C]) and hepatosplenomegaly (9/9), whereas 2 of 9 had lymphadenopathy. In these patients, a bone marrow aspiration was performed, and VL was detected in all 9 samples. They were treated with liposomal amphotericin B and had an excellent response rate. Pancytopenia resolved within a mean period of 17.6 (SD, 17.3) days (range, 8-60 days), and there was no relapse during a 2 years' follow-up. CONCLUSIONS In endemic countries, leishmaniasis is the main cause of febrile pancytopenia among children in whom hematologic malignancy has been ruled out.

Abstract
Cutaneous leishmaniasis (CL), an endemic disease in the littoral zones of the Mediterranean area, the Middle East, East Africa, and especially in Libya, has not been fully documented. The present study clarifies the clinico-epidemiologic profile of CL and the molecular genotyping of the Leishmania spp. in the Nalut district, Libya. Two hundred and twenty-three CL patients were examined at the out-patient clinics of Nalut Hospital from March 2006 to February 2007. CL was diagnosed by clinical, microscopic, culture, polymerase chain reaction (PCR), and PCR-restriction fragment length polymorphism (RFLP) analyses. The disease was observed year-round, with the highest prevalence between November and February. Fifty-nine percent of patients were younger than 20 yr. Nodulo-ulcerative lesions, indurated ulcers, papulo-ulcerative lesions, and subcutaneous nodular lesions were observed in 170, 25, 15, and 13 patients, respectively. Two hundred patients (89.7%) had dry type of lesions, whereas 23 patients (10.3%) presented a wet type of lesion. One hundred and fifty-nine (71.3%) of 223 patients were confirmed positive for CL by the presence of the amastigote form of Leishmania by stained Giemsa smear, and 170 (76.2%) were positive according to the presence of the promastigote form of Leishmania by culture in RPMI 1640 medium supplemented with 10% fetal bovine serum (FBS). PCR confirmed 203 (91.0%) positive cases. Genotyping of Leishmania spp. by RFLP analysis revealed that L. tropica was the most common species at all ages, and L . infantum was second under 20 yr of age. In summary, CL is endemic in the Nalut district, Libya; PCR was the most sensitive parasite diagnostic test, and L. tropica was the most common species.

Abstract
Leishmania infantum is endemic in the Maltese archipelago, a group of islands in the Mediterranean which are visited frequently by tourists from Northern European countries. The burden of leishmaniasis is highest in children who may present with cutaneous or visceral manifestations. We describe systematically the manifestations, diagnosis and management of leishmaniasis in children <14 years of age, who had a histopathological diagnosis of leishmaniasis in Malta, from 2004 to 2008. Eleven children were diagnosed with leishmaniasis; 8 children (15–44 months of age) had visceral disease and three (aged 9–13 years) suffered cutaneous infections. Prolonged high grade fever, pallor, hepatosplenomegaly, and pancytopenia were common presenting features of visceralisation. Diagnosis was based on the visualisation of amastigotes from bone marrow aspirates. Pentavalent antimonials were associated with treatment failure in two children, whilst liposomal amphotericin B was curative in all. Children with cutaneous leishmaniasis had dry crusted ulcero-nodular lesions on exposed areas which responded to intra-lesional instillation of sodium stibogluconate or to cryotherapy. Leishmaniasis should be included in the differential diagnosis of fever and hepatosplenomegaly or chronic cutaneous lesions in children who travel to Malta.

Abstract
We report a case of visceral leishmaniasis in a 66-year-old female with a history of MALT lymphoma in the gastrointestinal tract. The patient presented with major hemorrhage per rectum and perforation of the small intestine. Due to unexplained decreasing platelets, lymphoma bone marrow involvement was suspected and bone marrow examination was performed. Surprisingly, Leishman-Donovan bodies were detected. The low platelet count, caused by the combination of MALT lymphoma and visceral leishmaniasis, appears to have aggravated the symptoms of the intestinal lymphoma. Leishmaniasis should be suspected even among asymptomatic patients with immune compromising illnesses and a travel history to areas where leishmaniasis is endemic.

Abstract
Epidemiology, disease patterns, immunology, diagnosis, treatment and control measures of leishmaniasis are described. Various issues relating to leishmaniasis are highlighted: the relative lack of importance given to this disease compared with other infections, climate change and its possible impact on extension of endemicity of this infection, and new diagnostic tests which are improving diagnosis, especially in resource poor areas. Other important aspects discussed include the potential for newer oral therapy to change the way this disease is managed; Leishmania-HIV coinfection and groups at risk; and development of an effective vaccine.

Abstract
Este trabalho, realizado a partir de outubro de 2000 até janeiro de 2003, descreve as características clínico-epidemiológicas da leishmaniose visceral em Três Lagoas, Mato Grosso do Sul. Foram confirmados 149 casos da doença, com predominância do sexo masculino (71,1%). A faixa etária mais acometida foi de 0 a 4 anos (42%). Quanto ao quadro clínico, estiveram presente febre (97,3%), esplenomegalia (85,9%) e anemia (75,8%). Em 32 (21,5%) pacientes ocorreu infecção associada, predominando a pneumonia. Sobre as alterações laboratoriais observou-se mediana de hemoglobina de 8mg/dl e de leucócitos de 3.100 cel/mm³. O esfregaço de medula foi positivo em 90,6%. Dos 97,9% de pacientes tratados, 78,2% utilizaram antimoniato pentavalente. Ocorreram 8% de óbitos, metade deles portadores de infecção associada. O conjunto destes dados sugere mudanças no padrão fisiográfico de ocorrência da leishmaniose visceral na localidade, com expansão e urbanização da doença, necessitando atenção para o diagnóstico e tratamento precoces.

Abstract
BACKGROUND Visceral Leishmaniasis (VL) type in Turkey is consistent with the Mediterranean type of VL, a fatal debilitating disease, which is mostly seen in infants. METHODS Hospital records of 19 children with VL were retrospectively reviewed. The period of the study was from January 2000 to December 2003. RESULTS The median age of the patients was 36 months. None was coinfected with human immunodeficiency virus or known to be immunocompromised. Fever, pallor, hepatomegaly, splenomegaly, thrombocytopenia and elevated C-reactive protein were observed in all cases, anemia in 18 (95%), leucopenia in 17 (89.4%) and elevated erythrocyte sedimentation rate in 14 (77.7%) of the cases. A bone marrow aspirate was obtained in all cases and Leishmania amastigotes were detected in 15 (78.9%). Fifteen patients (78.9%) were treated initially with meglumine antimonate and four (21%) with sodium stibogluconate. The four patients who received sodium stibogluconate suffered from adverse side-effects during treatment and were subsequently treated with lipid formulations of amphotericin B. CONCLUSIONS Presentation of VL in the pediatric age group in Turkey is characterized by pallor, fever, splenomegaly and hepatomegaly. Hematological and biochemical indices are typical with cytopenias, hypoalbuminemia, and hyperproteinemia. In most of the cases, microscopic examination provided a positive diagnosis and the remaining patients were diagnosed by serology. Lipid formulations of amphotericin B may be useful in cases of treatment failure with antimonials or significant adverse effects of the drug.

Abstract
AIMS OF THE STUDY First, to describe liposomal amphotericin B (AmBisome use as first line treatment of pediatric visceral leishmaniasis and secondly, to evaluate the incidence of the disease in southern France (Provence - Alpes - Côte d'Azur - Corse). MATERIAL AND METHODS Retrospective chart review of children referred for visceral leishmaniasis from 1996 to 2003. RESULTS Thirty-two children under 15 years of age and suffering from visceral leishmaniasis were treated with liposomal amphotericin B as first line treatment. Clinical and biological features were usual: age <5 years, no immunodeficiency, spleen enlargement and fever, cytopenia. In this population, treatment effectiveness was evaluated to 97% (one relapse). Under treatment, patients quickly improved. Drug regimens varied from 18 to 24 mg/kg (day 1 to 5, and day 10). Four other children were not treated with first-line liposomal amphotericin B during the period. Thus, the incidence of pediatric visceral leishmaniasis was evaluated to be 0.61/100,000 children <15 years/year in the region (2.74 in the Alpes-Maritimes department, French Riviera, and 0.6 in the Bouches-du-Rhône department, Marseilles area). CONCLUSION Liposomal amphotericin B treatment is usual for children referred for visceral leishmaniasis in this region. This treatment may be approved regarding the high level of effectiveness and the low number of adverse events. A two days drug regimen with 20 mg/kg should be evaluated. Moreover, the incidence of the pediatric visceral leishmaniasis in southern France is decreasing, but local variations may be observed.

Abstract
Firm diagnosis of visceral leishmaniasis (kala-azar) requires organ aspiration and microscopic examination of tissue specimens. To determine the usefulness of noninvasive diagnosis by strip test detection of anti-K39 immunoglobulin (Ig) G antibody in blood specimens obtained by fingerstick, 143 Indian patients with suspected kala-azar (fever, splenomegaly, anemia) were studied. Of 120 strip test-positive subjects (subjects with presumed kala-azar [group A]), amphotericin B treatment induced clinical cure in 119. Of 23 strip test-negative subjects (subjects presumed to have other diseases [group B]), 16 had other disorders diagnosed at entry, 4 responded to empiric antimalarial therapy, 2 were proven to have kala-azar, and 1 died elsewhere after undergoing splenic aspiration. Six months after treatment ended, all 120 patients in group A and the 18 assessable patients in group B were healthy. In a region in India where visceral infection is prevalent, strip test detection of anti-K39 IgG is a clinically promising diagnostic guide in persons with suspected kala-azar.

Abstract
Visceral leishmaniasis is a vector-borne systemic infection, which affects half a million people each year in many areas of the world. Typical disease manifests with fever, hepatosplenomegaly, pancytopenia, and progressive deterioration of the host. Although molecular methods appear promising as a non-invasive diagnostic tool, definite diagnosis still relies on the demonstration of the parasite in tissue. Pentavalent antimonial compounds remain the mainstay of treatment worldwide, except in India. During the past decade, short courses of lipid formulations of amphotericin B were assessed and proved effective; however, their cost precludes their wide use in developing countries. Miltefosine, an oral active agent, was recently identified, and might fulfil our expectations for an effective, safe, easily administered and affordable antileishmanial treatment.

Abstract
Visceral leishmaniasis is suspected on the basis of clinical findings and a pancytopenic blood picture and is usually confirmed by the detection of amastigotes (Leishman-Donovan bodies) in a bone marrow aspirate. We describe a child on maintenance treatment for acute lymphoblastic leukaemia who developed visceral leishmaniasis and in whom amastigotes could not be detected in repeated bone marrow aspirates. Immunofluorescence antibody testing was positive. Immunocompromised patients in endemic areas who develop features of visceral leishmaniasis should have serological tests performed in addition to bone marrow aspiration in order to maximize the chances of making a diagnosis.
