One of the most frequent filariases in Africa is loiasis, or loaiasis, responsible for a large number of nematode infestations on that continent, where it represents a major public health problem, together with O.volvulus and M. perstans infestation4.
A diagnosis of loiasis was made and treatment with albendazole was started and doses were increased from 50 to 400 mg/d for 1 week and 600mg/d for the following 21 days, in combination with betamethasone 2 mg/d.
A diagnosis of loiasis should always to be considered in patients from endemic areas who complaining of pruritus symptoms that do not relate to allergies, difficult social conditions or housing problems.

 Filaria Journal | Full text | Combined Utilisation of Rapid Assessment Procedures for Loiasis (RAPLOA) and ...
RAPLOA (Rapid Assessment Procedure for loiasis), a newly developed rapid assessment procedure for loiasis that relates the prevalence of key clinical manifestation of loiasis (history of eye worm) to the level of endemicity of the infection (prevalence of high intensity), is a very useful tool to identify areas at potential risk of L.
The specific objectives were to (i) provide information on the prevalence and intensity of loiasis and onchocerciasis in an area where data was scarce, (ii) validate RAPLOA in different sites from where it was originally developed and (iii) to reinforce the validity of nodule palpation in an area of co-endemicity L.
The two tools have several similarities in their methodological approaches: they are carried out on individuals (adults or nearly-adults) of both sexes, who have been resident in a community for a long period of time, their sample size requirements are not conflicting, the exercises of interview and nodule palpation are very simply to execute.

In areas covered by the program where loiasis is also endemic, some patients with high levels of Loa loa microfilaremia develop encephalitis upon treatment with ivermectin (Gardon et al., 1997).
A double-blind, placebo-controlled trail of Albenazole in subjects with loiasis found that the drug was capable of reducing levels of microfilariae, eosinophils, and anti-filarial IgG (Klion et al., 1993) at a dose of 200 mg twice daily for 21 days.
Albendazole therapy appears to be effective in treating some loiasis patients that have remained uncured after multiple courses of DEC treatment (Klion et al., 1994).

 Final Report No.66 - Onchocerciasis: RAPLOA: a new, effective mechanism for identifying loiasis endemicity
A multicentre study was carried out to evaluate the use of specific clinical symptoms in the rapid assessment of loiasis endemicity.
The study showed that a simple rapid assessment procedure based on a restricted definition of Eye Worm can effectively identify communities where the endemicity of loiasis is high and where there is thus a risk of severe adverse reactions to ivermectin treatment.
Results demonstrate that RAPLOA is a rapid and simple tool for the assessment of the prevalence and intensity of loiasis at the community level.

 UpToDate Loiasis and mansonella infections
Although loiasis is not commonly associated with severe disease in either residents or visitors to endemic regions, it is a frequent reason for presenting for medical care in certain areas.
It is sometimes called "eyeworm" because the adult parasite may be found migrating across the subconjunctiva of the eye.
Infection appears to be occult in a large proportion of patients and remains undiagnosed; thus, the epidemiology of loiasis in many areas has not been clearly defined.

We conclude that doxycycline may not be an efficient therapy for loiasis.

We worked in 10 communities of a forest area presumed co-endemic for loiasis and onchocerciasis in the North-West Province of Cameroon where the mass-treatment with ivermectin had not been carried out.
For the first time, this study has demonstrated that the two rapid assessment procedures for loiasis and onchocerciasis can be carried out simultaneously by a survey team, in which a single individual can administer the questionnaire for RAPLOA and perform the nodule palpation for REA.

Microfilarial blood concentrations (may be required prior to and periodically during therapy with diethylcarbamazine; in loiasis, retinal hemorrhage and encephalopathy may occur with very high microfilarial blood concentrations
However, it is sometimes difficult to determine whether these reactions are caused by the death of microfilariae or by diethylcarbamazine itself.

 Filariasis   (Site not responding. Last check: 2007-10-01)
Recently, a 'new' filarial syndrome has been described as one of clinical and immunologic hyper-responsiveness found in expatriate visitors to regions endemic for loiasis.
This clinical syndrome is, of course, not really new, nor is it limited to loiasis, as similar clinical descriptions of patients with onchocerciasis, lymphatic filariasis, and other filarial infections also have been recorded previously.
Instead of developing the commonly described chronic clinical manifestations of their filarial infections, individuals who have grown up outside of the endemic regions and then moved to these regions and acquired a filarial infection manifest prominent signs and symptoms of inflammatory (including allergic) reactions to the mature or maturing parasites.
