Assessment of nutritional status among post-kala-azar dermal leishmaniasis patients in endemic areas of northern West Bengal, India.

CONTEXT: Nutritional status played significant roles in preventing infection of pathogens, expression of disease severity, and prognosis following treatment. Leishmaniasis is a neglected tropical disease affecting the poorest people and is generally undernourished. In the Indian subcontinent, malnutrition is found to be associated with visceral leishmaniasis (VL) but such reports for post kala-azar dermal leishmaniasis (PKDL) are not available.

OBJECTIVES

Assessment of nutritional status among PKDL cases from West Bengal, India.

METHODOLOGY: PKDL cases were searched by door-to-door visits. The nutritional status of the study participants was assessed by analyzing clinical, anthropometrical, and biochemical parameters. The data were analyzed using standard statistical methods with Minitab software.

RESULTS

A total of 42 PKDL (Group A), 38 with VL history (Group B), and 80 healthy control participants (Group C) were included. We noticed a higher rate of ocular and dermal abnormalities due to Vitamin A deficiency among PKDL patients. A lower range of body mass index was recorded among both Group A and B. The mean hemoglobin and Vitamin B12 level of Group A were significantly lower than Group C. The mean white blood cell count was significantly higher in Group A than other two groups.

CONCLUSION

The study revealed that PKDL patients were undernourished as evident by few clinical, anthropometrical, and biochemical parameters. The initiative of providing nutrient-rich food during the treatment of leishmaniasis by the Government of West Bengal is justified. A case-control study is highly suggested to evaluate the impact of such food supply during treatment on disease prognosis.
