Fascioliasis is a parasitic infection caused by the trematode Fasciola hepatica, which primarily affects the liver and bile ducts. Chronic cholecystitis, on the other hand, is a condition characterized by inflammation of the gallbladder, which can lead to various complications if left untreated. In this article, we will discuss a case of Fascioliasis associated with chronic cholecystitis in a woman from Sistan and Baluchestan province, a non-endemic region in Southeastern Iran.
The patient in question was a 42-year-old woman who presented to the hospital with complaints of abdominal pain, nausea, and vomiting. She had a history of cholecystitis and had undergone cholecystectomy (surgical removal of the gallbladder) four years ago. However, her symptoms persisted, and she was referred for further evaluation.
Upon examination, the patient was found to have an enlarged liver and evidence of bile duct obstruction. Laboratory tests revealed elevated liver enzymes and eosinophilia (an increase in the number of eosinophils, a type of white blood cell that is associated with allergic reactions and parasitic infections). An abdominal ultrasound showed multiple hyperechoic lesions in the liver, which were suggestive of Fascioliasis.
Further investigations, including a serological test for Fasciola antibodies and a stool examination for Fasciola eggs, confirmed the diagnosis of Fascioliasis. The patient was started on treatment with triclabendazole, a drug that is highly effective against Fasciola. She responded well to the treatment, and her symptoms improved significantly.
The association between Fascioliasis and chronic cholecystitis is not well established in the literature. However, there have been a few case reports of patients with chronic cholecystitis who were found to have Fasciola eggs in their bile ducts. It is thought that the presence of Fasciola in the bile ducts can cause inflammation and obstruction, leading to chronic cholecystitis.
Sistan and Baluchestan province is not considered an endemic region for Fascioliasis. However, there have been a few cases reported in the past, mostly in people who have consumed contaminated water or vegetables. The source of infection in this particular case was not identified, but it is likely that the patient consumed contaminated water or vegetables at some point in the past.
Fascioliasis is a neglected tropical disease that affects millions of people worldwide, mostly in developing countries. The disease is caused by the ingestion of metacercariae, the infective stage of the parasite, which are found in freshwater plants or watercress. The metacercariae migrate to the liver, where they mature into adult worms and lay eggs that are passed out in the feces. The eggs can contaminate water sources and infect snails, which serve as intermediate hosts for the parasite. The cercariae, the free-swimming stage of the parasite, emerge from the snails and infect humans or animals that come into contact with contaminated water or vegetation.
The clinical manifestations of Fascioliasis can vary from asymptomatic infection to severe liver damage and even death in some cases. The symptoms usually appear several weeks after infection and include abdominal pain, nausea, vomiting, fever, and eosinophilia. In chronic cases, the disease can lead to fibrosis, cirrhosis, and even hepatocellular carcinoma (liver cancer).
The diagnosis of Fascioliasis can be challenging, as the symptoms are non-specific and can mimic other liver diseases. Laboratory tests, including serology and stool examination, can help in the diagnosis. Imaging studies, such as ultrasound and computed tomography (CT), can reveal the characteristic hyperechoic lesions in the liver.
Treatment of Fascioliasis involves the use of antiparasitic drugs, such as triclabendazole, which is highly effective against the parasite. The drug is usually given in a single dose and can cure the infection in most cases. However, in some cases, a second dose may be necessary to achieve complete cure.
Prevention of Fascioliasis involves avoiding consumption of contaminated water or vegetables and improving sanitation and hygiene practices. In endemic areas, mass treatment of the population with antiparasitic drugs may be necessary to control the disease.
In conclusion, Fascioliasis is a parasitic infection that can cause chronic cholecystitis and other liver diseases. The disease is prevalent in many developing countries, and it can also occur in non-endemic regions, as seen in this case. Early diagnosis and treatment with antiparasitic drugs can cure the infection and prevent complications. Prevention of the disease involves avoiding consumption of contaminated water or vegetables and improving sanitation and hygiene practices.

False Assumptions Regarding Fascioliasis associated with chronic cholecystitis in a woman from Sistan and Baluchestan province, a non-endemic region in Southeastern Iran | BMC Infectious Diseases
Introduction
Fascioliasis is a parasitic infection caused by Fasciola hepatica or Fasciola gigantica. It is primarily a disease of herbivorous animals, but humans can also be infected. Chronic cholecystitis, on the other hand, is a condition characterized by inflammation of the gallbladder that persists over a long period of time. Both conditions can occur independently, but there is a common misconception that fascioliasis is always associated with chronic cholecystitis in women from non-endemic regions of Iran.
Misconception 1: Fascioliasis is always associated with chronic cholecystitis
While it is true that fascioliasis can cause cholecystitis, it is not always the case. In fact, cholecystitis is a relatively rare complication of fascioliasis. Most patients with fascioliasis do not develop cholecystitis, and most patients with cholecystitis do not have fascioliasis. Therefore, it is important to consider other causes of cholecystitis in patients from non-endemic regions of Iran.
Misconception 2: Chronic cholecystitis is always caused by fascioliasis in non-endemic regions of Iran
Cholecystitis can be caused by a variety of factors, including infections, gallstones, and autoimmune diseases. Fascioliasis is just one of many possible causes of chronic cholecystitis. Therefore, it is important to consider other possible causes of cholecystitis in patients from non-endemic regions of Iran, especially if they do not have a history of exposure to contaminated water or ingestion of raw aquatic vegetation.
Misconception 3: Only women are affected by fascioliasis-associated chronic cholecystitis in non-endemic regions of Iran
While it is true that women are more commonly affected by fascioliasis-associated chronic cholecystitis in endemic regions, this is not necessarily the case in non-endemic regions of Iran. In fact, men can also be affected by fascioliasis-associated chronic cholecystitis, especially if they have a history of exposure to contaminated water or ingestion of raw aquatic vegetation.
Misconception 4: Diagnosis of fascioliasis-associated chronic cholecystitis is straightforward
Diagnosis of fascioliasis-associated chronic cholecystitis can be challenging, especially in non-endemic regions of Iran. Clinical manifestations of this condition can be non-specific and overlap with other causes of cholecystitis. Laboratory tests, including serological tests and stool examinations, can be helpful in establishing the diagnosis, but they are not always definitive. Imaging studies, such as ultrasound and computed tomography, can also aid in the diagnosis, but they may not always show characteristic findings.
Misconception 5: Treatment of fascioliasis-associated chronic cholecystitis is simple
Treatment of fascioliasis-associated chronic cholecystitis can be complex and requires a multidisciplinary approach. Antiparasitic drugs, such as triclabendazole, are the mainstay of treatment for fascioliasis, but they may not always be effective, especially in cases of chronic infection. In addition, treatment of chronic cholecystitis may require surgery, such as cholecystectomy, in order to alleviate symptoms and prevent complications. Therefore, it is important to seek the advice of a specialist in infectious diseases and gastroenterology for the management of this condition.
