Assessment of the Impact of Morbidity Management and Disability Prevention for Lymphatic Filariasis on the Disease Burden in Villupuram District of Tamil Nadu, India.

BACKGROUND

The global program to eliminate lymphatic filariasis (GPELF) was started in 2003 with two strategies: the mass drug administration (MDA) to interrupt disease transmission and the morbidity management and disability prevention (MMDP) to provide the basic hygienic care to filariasis lymphedema patients. Among the two strategies, the MDA is well advanced and got the desired results, but the MMDP is lagging due to poor execution.

OBJECTIVES

To assess the awareness of MMDP and ongoing morbidity management practices by lymphedema patients and to estimate the impacts of the MMDP on the prevalence and severity of lymphedema.

MATERIALS AND METHODS

This study was conducted among 100 lymphedema patients in 7 filariasis endemic villages of Villupuram district, Tamil Nadu, India through interviews using a structured, pretested questionnaire. The grading and adenolymphangitis (ADL) attack determination were done by a clinician. The impact was assessed in terms of changes in the lymphedema grades, frequency of ADL attacks, and changes in the burden.

RESULTS

Of the 100 patients, 70% were aware of the program and among them, only 48% were practising MMDP regularly (i.e. two times per day). The majority of them (80%) were taking treatment during ADL attacks. The overall lymphedema grades reversal and progression were observed in 13% and 52% of cases, respectively.

CONCLUSION

This study has revealed that the second arm of the GPELF, "MMDP" has not yielded the desired results as evidenced by the incidence of frequent ADL attacks and advancement of lymphedema grades.
