microfilaremia

microfilaremia

 [mi″kro-fil″ah-re´me-ah]
the presence of microfilariae in the circulating blood.

mi·cro·fil·a·re·mi·a

(mī'krō-fil'ă-rē'mē-ă),
Infection of the blood with microfilariae. Microfilaremia caused by Wuchereria bancrofti is characterized by sharp nocturnal periodicity, apparently tied to the nocturnal habits of the vector mosquitoes; in geographic areas where mosquitoes are not strictly night-biters (as in areas of Polynesia), the microfilarial periodicity is modified or absent.
See also: periodic filariasis.

Synonym(s): microfilaraemia.

In a blood test performed in July, microfilaremia was confirmed in a few clinically normal chickens of the same flock.
Initially, loiasis was suspected as a diagnosis, given the location of the adult worm and presence of microfilaremia. However, the length (10 cm) of the adult worm did not correspond to a Loa loa worm, which can reach a maximum length of -7 cm.
In felids and other hosts, microfilaremia is either not present or transitory and present at low levels, while in humans the worms do not usually reach maturity [6].
A case of subcutaneous Dirofilaria (Nochtiella) repens with microfilaremia originating in Corsica.
Based on the patient's travel history to a Loa loa-endemic region, the attending physicians suspected loiasis but could not confirm microfilaremia despite increasing peripheral eosinophilia with repeated peripheral smears and Knott concentration tests on blood drawn at midday.
(7) Filariasis consists of spectrum of clinical presentations ranging from asymptomatic microfilaremia, acute lymphadenitis, chronic lymphadenitis, edema of limbs and genitalia & tropical pulmonary eosinophilia.
The International Task Force (WHO) has recommended that in mass treatment, diethylcarbamazine (DEC) is given to almost everyone in the community irrespective of whether they have microfilaremia or not, disease manifestations or no signs of infection in the area of high endemicity except children <2 years, pregnant women, and very sick patients.
In Aydin city, where the present authors residing and working, microfilaremia was detected with a rate of 13.9% among 158 dogs (25).
Microfilaremia and eosinophilia are common in the acute phase.

The overture of assays for circulating filarial antigen, the innovation of occult lymphatic pathology and renal disease in asymptomatic microfilaremics and the recognition of the role of bacterial infection in the pathogenesis of acute and chronic disease suggests that the old classification based on presence or absence of microfilaremia and/or chronic pathology is outdated.
While a single dose of ivermectin markedly reduces skin microfilarial loads up to 12 months, with a transient fall in microfilarial level (21), repeated doses of ivermectin are reported to lower the incidence of microfilaremia. Ivermectin is widely available through the Onchocerciasis Control Programme (OCP) in Nigeria and other west African countries (22) and it is currently the most accepted method for control of recrudescence of infection in an area where the parasite reservoir has been virtually eliminated by vector control (23).
