What causes Pelodera dermatitis?

Pelodera dermatitis is a rare, nonseasonal, acute dermatosis that results from invasion of the skin by larvae of the free-living saprophytic nematode Pelodera strongyloides. The larvae are ubiquitous in decaying organic matter and on or near the surface of moist soil but are only occasionally parasitic.

How is Pelodera dermatitis treated?

Discarding moist or dirty bedding and replacing it with clean, dry bedding was the first step taken in treating our Pelodera dermatitis cases. All dogs were treated with ectoparasiticides. A favourable response was achieved with organophosphates (cases 1–6) and with ivermectin (cases 7, 9, 10 and 11).

How do you get rid of Strongyloides?

The medicine of choice to treat strongyloidiasis is a single dose of the antiparasitic medication ivermectin (Stromectol). This drug works by killing the worms in your small intestine. Your doctor may also prescribe two courses of albendazole (Albenza), to be taken 10 days apart.

How do you get Strongyloides?

How do people get infected with strongyloides? Strongyloides stercoralis is classified as a soil-transmitted helminth. This means that the primary mode of infection is through contact with soil that is contaminated with free-living larvae.

How does strongyloides affect the skin?

Cutaneous symptoms include chronic urticaria and larva currens- a recurrent serpiginous maculopapular or urticarial rash along the buttocks, perineum, and thighs due to repeated auto-infection. It has been described as advancing as rapidly as 10cm/hr.

How big are strongyloides?

Strongyloides stercoralis free-living adults. Free-living adult males measure up to 0.75 mm long; free-living females measure up to 1.0 mm long.

Is Strongyloides curable?

Treatment options include ivermectin, tiabendazole and albendazole. The drug of choice for strongyloidiasis is ivermectin, which kills the worms in the intestine at 200 μg/kg (7). Two doses are given 1–14 days apart, which has a cure rate of 94–100%.

How long does Strongyloides persist in gut?

Strongyloides parasites can persist and replicate inside human hosts for up to 30 years, causing minimal or no symptoms. However, in an immunocompromised host, they can cause a serious and life-threatening infection.

How do you know if you have strongyloidiasis?

Strongyloidiasis is infection with Strongyloides stercoralis. Findings include abdominal pain and diarrhea, rash, pulmonary symptoms (including cough and wheezing), and eosinophilia. Diagnosis is by finding larvae in stool or small-bowel contents or occasionally in sputum or by detection of antibodies in blood.
