Zoledronic acid is given as an intravenous infusion; a single dose is effective for two years. This is recommended for most people at high risk with active disease. Calcitonin
Salcatonin, also called calcitonin-salmon is a synthetic copy of a polypeptide hormone secreted by the ultimobranchial gland of salmon. Miacalcin is administered by injection, three times per week or daily, for 6–18 months. Repeat courses can be given after brief rest periods. Miacalcin may be appropriate for certain patients but is seldom used. Calcitonin was putatively linked to increased chance of cancer. The European Medicines Agency (EMA) recommended that calcitonin be used only on a short-term basis for 3 conditions for which it had previously been approved in the European Union: Pagets disease, acute bone loss resulting from sudden immobilization, and hypercalcemia caused by cancer. As a solution for injection or infusion, calcitonin should be administered for no more than 4 weeks to prevent acute bone loss resulting from sudden immobilization, and normally for no more than 3 months to treat Pagets disease, the EMA said. The agency did not specify a time frame for the short-term use of calcitonin for treating hypercalcemia caused by cancer. The EMA based its recommendations on a review of the benefits and risks of calcitonin-containing medicines.
Portal hypertension may be present, resulting in other conditions including enlarged spleen, hematemesis, and melena. These problems can severely affect the patients quality of life. In a 10-year period between 1995 and 2005, only 10 patients were surgically treated for Caroli disease, with an average patient age of 45.8 years.After reviewing 46 cases of Caroli disease before 1990,  21.7% of the cases were the result of an intrahepatic cyst or nonobstructive biliary tree dilation, 34.7% were linked with congenital hepatic fibrosis, 13% were isolated choledochal cystic dilation, and the remaining 24.6% had a combination of all three. Causes
The cause appears to be genetic; the simple form is an autosomal dominant trait, while the complex form is an autosomal recessive trait. Females are more prone to Caroli disease than males. Family history may include kidney and liver disease due to the link between Caroli disease and ARPKD. PKHD1, the gene linked to ARPKD, has been found mutated in patients with Caroli syndrome. PKHD1 is expressed primarily in the kidneys with lower levels in the liver, pancreas, and lungs, a pattern consistent with phenotype of the disease, which primarily affects the liver and kidneys. The genetic basis for the difference between Caroli disease and Caroli syndrome has not been defined. Diagnosis
Modern imaging techniques allow the diagnosis to be made more easily and without invasive imaging of the biliary tree. Commonly, the disease is limited to the left lobe of the liver.
