Clinico-laboratory profile of 45 filarial arthritis cases.

ABSTRACT

This prospective observational study was done during the period from January 2000 to December 2004 including 45 cases of lymphatic filariasis manifested with acute arthritis. Different investigations were carried out to exclude allergy, parasitic and infectious diseases, autoimmune disorder and malignancy. They were given standard treatment with oral non-steroidal anti-inflammatory drugs (NSAIDs). Articular symptoms were not relived satisfactorily. Later they were given oral corticosteroids. During treatment slight relief of symptoms were noted, but all sign-symptoms reappear after withdrawal of corticosteroid drugs. Treatment with oral diethylcarbamazine citrate (DEC) (150 mg/day) for 3 weeks showed complete resolution of arthritis. No side effects or relapse were encountered. The basic mechanism of relief of pain remains unknown. It was assumed that during benign course of lymphatic filariasis, development of arthritis result most likely due to reaction against some occult agents in the joints.
