Onchocerciasis treatment

Onchocerciasis (rivierblindheid)

The treatment for onchocerciasis is ivermectin (Mectizan®). Ivermectin paralyses and kills microfilariae, relieving intense skin itching and halting the progression towards blindness. It also prevents adult worms from producing more microfilariae for a few months following treatment, so reduces transmission Ivermectin is now considered to be the drug of choice for the treatment of onchocerciasis. The prognosis for people with onchocerciasis has changed greatly. It is now possible to avoid the heavy infection loads seen previously, and patients, especially expatriates, may have their symptoms relieved by treatment Moxidectin is an antiparasitic drug that was approved by the FDA in June 2018 to treat onchocerciasis in patients aged 12 years or older. The WHO initiated clinical trials for use in onchocerciasis.. Treatment WHO recommends treating onchocerciasis with ivermectin at least once yearly for between 10 to 15 years. Where O. volvulus co-exists with Loa loa, treatment strategies have to be adjusted Treatment The standard treatment for onchocerciasis is ivermectin (150-µ g/kg given orally ever 6 to 12 months). Ivermectin is a highly lipophilic [ 49 ], 16-membered macrocyclic lactone from Streptomyces avermitilis [ 50 ]


Onchocerciasis, or river blindness, is a neglected tropical disease (NTD) caused by the parasitic worm Onchocerca volvulus.It is transmitted through repeated bites by blackflies of the genus Simulium.The disease is called river blindness because the blackfly that transmits the infection lives and breeds near fast-flowing streams and rivers, mostly near remote rural villages Onchocerciasis is diagnosed by finding the parasites in skin nodules, skin biopsies, or skin scrapings. The treatment is the antiparasite drug ivermectin, given once or twice a year for about 10-15 years; the antibiotic doxycycline may also be utilized

  1. Onchocerciasis is a neglected tropical disease (NTD), a category of disease that tends to specifically devastate the underprivileged. Common in many poorer areas, river blindness can condemn those who cannot afford or find treatment for blindness and serious pain
  2. Receiving treatment for onchocerciasis can prevent long-term issues, such as blindness and permanent skin damage. A doctor may prescribe the antiparasitic medication ivermectin to kill the worm..
  3. Onchocerciasis is a typical condition of irritation in the eye, which can further turn into redness, inflammation and in extreme cases, blindness. It is also known as 'river blindness' and is caused by the infection with the parasitic worm 'onchocerca volvulus'. This infection is the second most common reason for blindness and can be.
  4. If you get onchocerciasis, early treatment can prevent or reduce long-term problems. Programs like the African Programme for Onchocerciasis Control (APOC) and the Onchocerciasis Control Programme (OCP) have prevented blindness in over 200,000 people. If you have the infection, anti-parasitic drugs can reduce the number of parasites in the body
  5. No treatment is effective against adult Onchocerca. Ivermectin (200 mcg/kg) and moxidectin (400 mcg/kg) are efficacious (>99%) against microfilariae and produce marked clinical improvement in horses with onchocercal dermatitis

Surgical Care Removal of all subcutaneous nodules can be curative; however, many nodules are difficult to find. Background Onchocerciasis is a chronic parasitic disease caused by the filarial nematode Onchocerca volvulus Goals for elimination of the disease. Current available treatment has not permitted elimination of the transmission of onchocerciasis. Moxidectin is a new promising treatment which could substantially reduce transmission of the parasite between annual treatments and thus decrease the number of years of treatments required to achieve parasite elimination In onchocerciasis, it has been established that treatment with doxycycline at 100 mg per day for six weeks leads to the long-term sterility of adult female worms 22, 23. This effect is probably permanent because there is no evidence for the reappearance of Wolbachia or for the resumption of embryogenesis in a large series of extirpated. Annual treatment has been the principal treatment strategy for onchocerciasis control in Africa and it has also already achieved interruption of transmission and elimination of infection in several foci. However, the success of annual treatment does not exclude the use of other intervention strategies for specific purposes This treatment kills only the larvae, which successfully alleviates the cutaneous symptoms of onchocerciasis, but it does not kill adult worms. Following a period of temporary sterility, the adult worms may resume production of larvae, which cause symptoms to return, requiring repeated treatment every 6-12 months
