Entire Body System
Rigor
- Excerpts from historical and/or anecdotal reports While rigorous data on LF distribution in L. loa areas is limited, there are many anecdotal and historical reports that W. bancrofti across Central Africa is low or absent.[parasitesandvectors.biomedcentral.com]

Hepatosplenomegaly
- Chest and heart were essentially normal, and there was no hepatosplenomegaly.[journals.plos.org]
Eyes
Photophobia
- The child was brought to the consultation with a 3-month history of irritability, insomnia, painful red eye, photophobia, and tearing.[ncbi.nlm.nih.gov]
- Case Presentation A 25-year-old woman from Sayaya village in Katsina State, northwestern Nigeria, presented to our eye clinic with a three-month history of redness, pain, photophobia, tearing, and itching, and a two-month history of gradual loss of vision[journals.plos.org]
Conjunctival Hyperemia
- The left eye examination revealed a visual acuity of light perception, conjunctival hyperemia, a clear cornea, and a live and active thread-like worm in the anterior chamber ( Fig 1 ).[journals.plos.org]
Red Eye
- Keywords: Loa loa, red eye, Cameroon Introduction Loa loa is commonly seen in the adnexae of the eye and subcutaneous tissues.[ncbi.nlm.nih.gov]
Blepharospasm
- The right eye examination revealed blepharospasm, significant lid edema, hyperhemic conjunctiva, and a mobile living whitish organic foreign body in the anterior chamber ( Figure 1 ). The left eye was quiet with no abnormality detected.[ncbi.nlm.nih.gov]
Miosis
- This examination revealed in the right eye, a moderate edema of the cornea, a white mobile worm in the anterior chamber, a hypo-pyon, a miosis with posterior synechiae of 360 , a cataract, and high intraocular pressure (of 30 mm Hg as measured with tonopen[ncbi.nlm.nih.gov]
Psychiatrical
Negativism
- The patient was treated with ivermectin 12 mg on the first day followed by albendazole 400 mg every 12 hours for 21 days with a reduction but no negativization of the parasitaemia and no collateral effect.[ncbi.nlm.nih.gov]
Urogenital
Incontinence
- By day 2 (D2), many patients experienced confusion, agitation, dysarthria, mutism and incontinence. Some cases of coma were reported as early as D2. The severity of adverse effects increased with higher microfilarial loads.[en.wikipedia.org]
Neurologic
Dysarthria

Prognosis
- Prognosis The prognosis in filariasis is good if infection is recognized and treated early. Filarial diseases are rarely fatal, but the consequences of infection can cause significant personal and socioeconomic hardship for those who are affected.[emedicine.com]
Etiology
- (See Pathophysiology and Etiology.) [13] As with most helminths, adult filarial parasites replicate in a definitive host. The adult worm burden in an individual cannot increase unless the host is exposed to additional microfilaria.[emedicine.com]

- It is targeted for elimination and is one of the five neglected tropical diseases (NTDs) that are primarily controlled by preventive chemotherapy.[parasitesandvectors.biomedcentral.com]
- Dead microfilariae within the uteri of the female worm degenerate and prevent further microfilarial production for 6-12 months. Ivermectin not only kills microfilariae, it is also a microfilarial suppressant.[emedicine.com]
