Fascioliasis - Infectious Diseases - MSD Manual Professional Edition Galba truncatula is the main snail host in Europe, partly in Asia, Africa, and South America. Ectopic infections involving the subcutaneous tissue and other organs inside and outside the abdomen are reported and have been summarized by Taghipour et al.13 However, their prevalence has not been established in endemic areas and are not common at the community level. eggs can be difficult to distinguish from Fasciolopsis buski eggs, although the abopercular end of Fasciola spp. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. Fairweather I, Brennan GP, Hanna REB, Robinson MW, Skuce PJ. These forms usually have intermediate morphologic characteristics (e.g. They also had acute edematous pancreatitis and were treated by extraction of live Fasciola hepatica by balloon during ERCP and conservative management. Free swimming cercariae disperse a few meters away from the snail host usually following water currents. A specific indirect hemagglutination assay (IHA) using purified adult Fasciola hepatica F1 antigen (Laboratoires Fumouze Diagnostic, Levallois Perret, France; cut-off 1/320) was used for serological diagnosis of fascioliasis. The disease is a plant-borne trematode zoonosis, [3] and is classified as a neglected tropical disease (NTD). Fasciola hepatica and F. gigantica are primarily parasites of domestic and wild ruminants (most commonly, sheep, cattle, and goats; also, camelids, cervids, and buffalo). Inclusion in an NLM database does not imply endorsement of, or agreement with, The tegument facilitates this adsorption by containing many small folds to increase the surface area. 3 Gastroenterology and hepatology, National Hepatology and tropical medicine research institute, Cairo, Egypt. The snail intermediate hosts for Fasciola spp. Cringoli G, Maurelli MP, Levecke B, et al. Three patients were sisters and were admitted to the hospital on the same day. In the blood there is an increase in white blood cells of the type called eosinophils, a common finding in worm infections. Torres GB, Iwashita AT, Vargas CM, Lujn LV, Bianchi HA, Casanova RT. Economic impact of the liver condemnation of cattle infected with, Prevalence of bovine fasciolosis and its economic loss due to liver condemnation at Wolaita Sodo Municipal Abattoir, Ethiopia. Although F. hepatica and F. gigantica are distinct species, intermediate forms that are thought to represent hybrids of the two species have been found in parts of Asia and Africa where both species are endemic. In addition, they both require high levels of moisture in the air, as both are at risk of desiccation. Patients who were admitted to our clinic and were diagnosed with Fasciola hepatica infection between January 2008 and February 2011 were prospectively enrolled in this study. The laboratory findings before treatment (Table (Table1)1) showed that mild anemia was present in 2 (25%) patients, eosinophilia in 4 (50%), and elevations in the ESR in 4 (50%), ALT in 7 (87%), AST in 6 (75%), ALP in 4 (50%), GGT in 7 (87%), and total bilirubin in 3 (38%) patients. Diagnosis of fascioliasis may be delayed because of the wide spectrum of the differential diagnosis and the low incidence of Fasciola hepatica infection[3]. Microscopic examination of fecal specimens for Fasciola hepatica eggs revealed a positive result for only 2 (7%) of the 30 patients, one with biliary and one with hepatic phase. From the seminal vesicle projects the ejaculatory duct, and this opens into the genital atrium, and many prostate glands surround this opening. Belgin G, Kank Yksek S, Tezer H, et al. Echenique-Elizondo M, Amondarain J, Lirn de Robles C. Fascioliasis: an exceptional cause of acute pancreatitis. [4] Because of its relatively large size and economic importance, it has been the subject of many scientific investigations and may be the best-known of any trematode species. Detection of Fasciola spp. This work has been carried out in accordance with the Declaration of Helsinki (2000) of the World Medical Association. Co-infection of cattle with Fasciola hepatica or F. gigantica and It may also help rule out pseudofascioliasis associated with ingestion of parasite eggs in sheep or beef liver. The burden of infection is unclear, and studies have shown the geographic expansion of fascioliasis in human and livestock likely related to climate change. [13] Its also used for renewal of the surface plasma membrane and the active uptake of nutrients, and the uptake of some compounds (e.g. The presence of risk factors such as exposure to endemic areas, raw water plants, or untreated water may raise the clinical suspicion.63 The signs and symptoms of fascioliasis are not specific but certain combinations of these may suggest the infection. Prevalence, coinfection, and risk factors associated with Fasciola As a disease of cattle and sheep, fascioliasis has serious economic consequences. Center: Adult Fasciola hepatica fluke stained with carmine (30mm x 13mm). Before ERCP, we considered the diagnosis of fascioliasis in 4 (50%) patients with eosinophilia. They then migrate through the intestines and liver, and into the bile ducts. However, most microscopy techniques have a low sensitivity and require repeated testing and egg concentration. Fasciola hepatica, also known as the common liver fluke or sheep liver fluke, is a parasitic trematode (fluke or flatworm, a type of helminth) of the class Trematoda, phylum Platyhelminthes. Symptoms include abdominal pain in the right upper quadrant, obstructive . Our group documented treatment failures after multiple courses of treatment in 7/19 (37%) patients referred to our center for treatment.83 Ramadan et al reported on 67 Egyptian patients with acute fascioliasis treated with a single triclabendazole dose. During the acute phase, patients may develop an incapacitating prolonged febrile illness that may remain undiagnosed for weeks even in endemic areas.14,15 The migrating parasites may erode into blood vessels causing large and sometimes life-threatening subcapsular liver hematomas.1517 In the acute and chronic phases, patients can present with cholangitis or liver abscesses associated with bacteria carried by the parasites or obstruction of bile flow.16 The association of chronic fascioliasis with liver fibrosis, cirrhosis and biliary tree disease has been reported in the literature and studied in animals but has not been characterized in humans.18 Most importantly, patients with asymptomatic, acute, or chronic fascioliasis can experience significant weight loss and anemia.1416,19 Young children are especially vulnerable to the devastating long-term complications associated with undernutrition and anemia such as stunting and poor neurocognitive development. The genome contains many polymorphisms, and this represents the potential for the fluke to evolve and rapidly adapt to changes in the environment, such as host availability and drug or vaccine interventions. Two accepted species, Fasciola hepatica and Fasciola gigantica, infect a wide range of mammals including livestock and humans. School-age children are disproportionately affected by Fasciola infection in highly endemic countries. Fascioliasis is a neglected zoonotic infection with a global distribution lacking a precise estimation of infection and disease burden. Fasciola infection has been reported in 81 countries.1 Fascioliasis is considered a neglected zoonotic disease by the World Health Organization. Nonspecific symptoms/signs (e.g., abdominal pain, nausea, vomiting, hepatomegaly, malaise, fever, cough) and laboratory abnormalities (e.g., peripheral eosinophilia, elevated transaminase levels) may develop. Triclabendazole and bithionol are effective agents for the treatment of fascioliasis[8]. hepatica. Previous research . The authors report no conflicts of interest for this work. The package insert suggests caution in human known to have or taking other medications that prolong the QTc interval.79. Fasciola hepatica, also known as the common liver fluke or sheep liver fluke, is a parasitic trematode (fluke or flatworm, a type of helminth) of the class Trematoda, phylum Platyhelminthes. Fanke J, Charlier J, Steppin T, von Samson-himmelstjerna G, Vercruysse J, Demeler J. Arias-Pacheco C, Lucas JR, Rodrguez A, Crdoba D, Lux-Hoppe EG. Liver flukes is the general name for those digenean trematodes (Phylum Platyhelminthes - Class Trematoda - Subclass Digenea) that live in the adult stage in the liver, the bile ducts, or the gallbladder of vertebrates. Low allelic diversity in vaccine candidates genes from different locations sustain hope for. Intermittent long-standing right upper quadrant pain, anemia, and/or stunting in children from endemic areas should also make the clinician think about Fasciola infection. Development of two FhSAP2 recombinant-based assays for immunodiagnosis of human chronic Fascioliasis. It is considered a safe drug based on decades of experience using it around the world and a limited set of safety studies. Introduction. sharing sensitive information, make sure youre on a federal [36] Therefore, an infection from F. hepatica can make it difficult to detect bovine tuberculosis; this is, of course, a major problem in the farming industry. Traumatic hepatitis occurs as immature flukes . In addition to classically defined hepatic phase and biliary phase fascioliasis, some cases may have overlap of these two phases with or without acute pancreatitis. The migratory phase can last more than 12 weeks and causes acute symptoms characterized by fever and right upper quadrant pain associated with high eosinophil counts and hypodense track like lesions on liver imaging studies (Figure 1). [25] The number of genes predicted is 14,642. Association of Fasciola hepatica Infection with Liver Fibrosis All of the patients in this study resided in rural areas and had a history of consuming watercress grown in areas where sheep were raised. [31], F. hepatica's tegument protects it from the enzymes of the host's digestive system, whilst still allowing water to pass through.
