Lymphoedema and its management in cases of lymphatic filariasis: the current situation in three suburbs of Matara, Sri Lanka, before the introduction of a morbidity-control programme.

Using in-depth interviews, information on the current state of lymphoedema management was collected from 101 cases of lymphatic filariasis with lymphoedema in three suburbs of Matara. The interviews were conducted prior to the introduction of a programme of community home-based care (CHBC) that incorporates modern lymphoedema-management strategies. Thirty-two of the interviewees had severe lymphoedema (of grade III or above). The male interviewees had significantly more entry lesions than the female. Most of the subjects had suffered from episodes of limb pain with fever, although the incidence of these episodes appeared unrelated to the severity of the lymphoedema. The frequency of the episodes of limb-pain/fever in the 12 months prior to the interviews appeared unrelated either to the level of daily hygiene, which was generally poor, or to the frequency of bathing. Many (65%) of the subjects paid no attention to limb care when bathing, and 44% did not use footwear. Over 80% made no effort to keep their afflicted limbs elevated, and 95% did not exercise. Most of the female interviewees felt shameful of their condition and were, in consequence, less likely to attend government clinics, for treatment, than the male interviewees. The drug treatment that the interviewees had received was often inadequate, and most had stopped seeking treatment because they had not perceived any significant treatment-attributable improvement in their condition. Modern lymphoedema-management strategies (based on regular washing, careful drying, and treatment, with antifungal, antibiotic or emollient creams, of the affected limbs, limb elevation, exercise, and use of footwear) had not reached the study communities and the local physicians were not aware of them. When dermatology life-quality indexes (DLQI) were calculated for the interviewees, the 26 most impaired subjects gave scores of 5-15 (mean=8.6). The DLQI for these subjects will be regularly re-evaluated, as a measure of the effectiveness of the CHBC programme that has now begun.
