Insights
This study on childhood visceral leishmaniasis in Brazil found a high case fatality rate of 10.2%, primarily due to infections and bleeding. Early recognition and management of visceral leishmaniasis are crucial for better outcomes.
Area of Science:
- Tropical medicine
- Pediatric infectious diseases
- Parasitology
Context:
- Visceral leishmaniasis (VL) is a severe parasitic disease affecting children in endemic areas.
- Socioeconomic factors, such as poor sanitation and limited education, are associated with VL prevalence.
- This study examines VL in a pediatric referral hospital in northeastern Brazil.
Purpose:
- To detail the clinical and epidemiological characteristics of pediatric visceral leishmaniasis cases.
- To report on treatment strategies and the overall case fatality rate.
- To identify key factors contributing to mortality in children with VL.
Summary:
- A retrospective analysis of 431 children with visceral leishmaniasis revealed common symptoms like splenomegaly and fever.
- Laboratory findings indicated severe anemia and thrombocytopenia.
- Glucantime was the primary treatment, but the case fatality rate remained high at 10.2%, with complications like infections and bleeding being major causes of death.
Impact:
- Highlights the significant burden of visceral leishmaniasis in pediatric populations.
- Underscores the need for improved public health interventions and sanitation in endemic regions.
- Emphasizes the importance of healthcare worker training for early diagnosis and management of VL and its complications.
Objective:
To describe the clinical and epidemiological features of children with visceral leishmaniasis admitted to a pediatric referral hospital, and to describe treatment measures and the case fatality rate.
Methods:
Retrospective analysis of biological, demographic, clinical and laboratory data from children with visceral leishmaniasis admitted to Instituto Materno Infantil de Pernambuco (Recife, state of Pernambuco, northeastern Brazil) between 1996 and 2001.
Results:
431 children were included in the study. Age ranged from 4 months to 13.7 years. 50.3% were female and 82.5% came from the interior of the state of Pernambuco. 70% of the patients lived in brick homes, and 70% were not served with piped water and sewage services. Average maternal schooling was 3 years. Clinical presentation included splenomegaly (97%), fever (95.6%) and malnourishment (44.5%). Associated infections were diagnosed in 10.9% of cases. The mean values for laboratory variables were: hemoglobin 6 g/dl, leukocyte count 3,516/mm(3), and platelet count 118,641/mm(3). The first line treatment used in 98% of the cases was glucantime. Amphotericin B was used in seven cases. The case fatality rate was 10.2%. The main immediate causes of death were associated infections, bleeding and liver failure.
Conclusions:
Health care workers should be trained for the early recognition and appropriate management of visceral leishmaniasis and its complications.
