Symptoms of chronic infection are subtle and similar to those seen with Clonorchis and Opisthorchis described above. Symptoms are associated with migration of the larval parasite through liver parenchyma (see life cycle below), and include abdominal pain, cough, urticaria and fever. The acute phase may last for a few months and occurs within a few weeks of infection. Hepatomegaly and right upper quadrant tenderness may be observed both in the acute and chronic setting.ĭistinct syndromes are associated with the acute and chronic phases of infection: Chronic symptoms include abdominal pain and discomfort, weight loss and anorexia. High-grade fever, arthralgia and lymphadenopathy as well as abdominal pain may occur after O. sinensis, urticaria, right upper quadrant abdominal pain and fever may develop. What are the clinical manifestations of infection with this organism?Īcute infection with C. The adult dosage of nitazoxanide is 500mg po bid (twice a day) for 7 days, with food. ![]() Paragonimus may be also treated with triclabendazole, 10mg/kg as a single oral dose which may be repeated.įor Fasciola infection, nitazoxanide may also be effective but is unproven. viverrini but is not yet clinically available in the US. A single 400mg dose of tribendimine has also been highly effective in initial clinical trials against both C. Opisthorchis and Clonorchis: Albendazole at 10mg/kg/day for 10 days may be used if praziquantel is not available or contraindicated but is not FDA approved for this indication. What alternative therapies are available? Seroreversion (loss of detectable antibodies) usually is noted 6 to 12 months after cure.Īre there issues of anti-infective resistance?Ĭlinically important resistance of liver flukes to praziquantel has not been observed but low cure rates for schistosomiasis have been reported, indicating the possibility of development of resistance in the future. Fasciolaserologic testing can be used to assess the response to therapy. Triclabendazole is not available in the US for human use but may be obtained from the CDC. Two doses 12-24 hours apart may also be given for severe infections. A single oral dose of 10mg/kg is administered. Triclabendazole is the first-line therapy for F. Praziquantel is FDA-approved but considered investigational for the treatment of intestinal flukes.įor cerebral disease, a short course of corticosteroids may be given with praziquantel to minimize the inflammatory response to dying flukes. Observed side effects include dizziness, sleepiness, headache, and diarrhea, but are generally transient. Praziquantel is administered at 25mg/kg given orally three times a day for two days. Praziquantel causes a spastic paralysis of the worms and alteration and disintegration of the worm tegument by incompletely understood mechanisms. It is also the first-line therapy for all the intestinal flukes and Paragonimus infection. ![]() Numbered structures include: mouth, sucker anterior, sucker posterior, penis, intestine, uterus, ovary, ootype, vas deferens, mehlis gland, yolk duct, testes and yolk.Praziquantel is the drug of choice for Clonorchis and Opisthorchis species.
