Filariasis

Filariasis is a parasitic and infectious tropical disease, caused by the thread-like parasitic filarial worms, Wuchereria bancrofti, Brugia malayi, and Brugia timori, all transmitted by mosquitoes. It is extremely rare in Western countries. Loa loa is another filariasis of humans, transmitted by the horse-fly. more...

The most spectacular symptom of filariasis is elephantiasis (swelling in the genitals or limbs), which was the first disease discovered to be transmitted by insects. Elephantiasis is caused when the parasites lodge in the lymphatic system.

In 1866, Otto Wucherer demonstrated the presence of microfilaria, or filaria larva, in urine. In 1871, Timoth Lewis discovered the presence of microfilaria in peripheral blood; later, in 1876, Joseph Bancroft discovered the adult form. Finally in 1878, Patrick Manson observed the development of Wuchereria bancrofti in mosquitos.

Filariasis is endemic in tropical regions of Asia, Africa, Central and South America.

Elephantiasis affects above all the lower extremities, whereas ears, mucus membranes, and amputation stumps are rarely affected; however, it depends on the species of filaria. Wuchereria bancrofti can affect the legs, arms, vulva, breasts, while Brugia timori rarely affects the genitals. Infection by Onchocerca volvulus and the migration of its microfilariae through the cornea is a major cause of blindness (Onchocerciasis).

VALIDATE OF OG4C3 ELISA AND ICT CARD TEST IN BANCROFTIAN FILARIASIS SURVEY
From Revista do Instituto de Medicina Tropical de Sao Paulo, 11/1/03 by de Oliveira, Conceicao Maria

The classical methods for the diagnosis of bancroftian filariasis by the way of microscopic examination of thick blood smears, collected usually at night, are not sensitive enough neither perfectly trustful. Other available methods have been considered as more practical, as the Og4C3 ELISA and ICT card test. This work try to validate those methods using a population survey realized in an endemic area in Northeast of Brazil. Og4C3, ICT and thick blood film, the last used as a gold standard, were compared with the data of epidemiological surveillance. The Og4C3 showed a 96.1% sensibility, a negative predictive value of 98.7% and a precision of 87.7%. The ICT showed a 94.4% sensibility, a negative predictive value of 97.1% and a precision of 91.9%. The most useful method is the one which present a higher sensibility and a higher negative predictive value. This dissertation argues that neither Og4C3 nor ICT can be considered ideal tests. Notwithstanding, ICT is indicated in this work as an adequate method to be used in Metropolitan Region of Recife, because of its better general results and because it is the more practical.
