Confección por dos filarias (Loa loa y Mansonella perstans) en una paciente proveniente de Guinea

Abstract

We present a case of mixed infection by two filariae (Loa loa and Mansonella perstans). It seems that the infection was suspected due to a pronounced eosinophilia in a routine analysis. Sheathed and unsheathed microfilariae were observed in the spread of peripheral blood, which enabled a diagnosis to be established of mixed infection by filariae. The definitive diagnosis of the species was carried out at the National Centre of Microbiolgy of Majadahonda. A treatment was initiated with dietilcarbamazina and mebendazole which resulted in the patient's being cured and in the elimination of the microfilariae in the patient's blood. Filariasis is still endemic in many countries. Due to the increase of travellers to such zones and the migratory movements from such areas it is not unusual for us to come across such a diagnosis. The implantation of massive treatments against filariae in endemic zones by the World Health Organisation is reducing their transmission and is managing to eliminate the disease in some areas.

Imported Loa loa filariasis: three cases and a review of cases reported in non-endemic countries in the past 25 years

“…These 52 cases, plus the expatriate patient described in the case reports above, are summarized in Table 2. Sixty-one cases (60.4%) were reported from Europe 8,12,16,17,[19][20][21]24,[26][27][28][29][31][32][33][34][35][36][37]42,43,[45][46][47][48][51][52][53][54]56,59,61,63,64,67,69,70,[72][73][74]77,[79][80][81][82][83][86][87][88][90][91]<...>…”

“…The African country of acquisition of loiasis was not specified in nine cases; 8,11,14,16,29,49,61,73,89 56 Cameroon and Congo, 59 and Cameroon, Nigeria, and Niger 66 ). Microfilaremia was more common in immigrants (78.0%) 7,13,[21][22][23]26,31,35,37,39,40,47,48,52,58,61,63,67,70,74,75,80,82,[85][86][87][88]91,92 (including PR cases) than in expatriates and travelers (Table 3). In contrast, peripheral blood eosinophilia (95.3%) [8][9][10][11][12]14,16,[18]…”
