The large scale, international FIELD and ACCORD-Eye trials found that fenofibrate therapy reduced required laser treatment for diabetic retinopathy by 1.5% over 5 years, as well as reducing progression by 3.7% over 4 years. Further studies looking at the role of fenofibrate in the progression of diabetic retinopathy as the primary outcome is warranted to understand its role in this condition. Although no statistically significant cardiovascular risk benefits were identified in these trials, benefits may accrue to add on therapy to patients with high triglyceride dyslipidaemia currently taking statin medications.Fenofibrate appears to reduce the risk of below ankle amputations in patients with Type 2 diabetes without microvascular disease. The FIELD study reported that fenofibrate at doses of 200 mg daily, reduced the risk for any amputation by 37% independent of glycaemic control, presence or absence of dyslipidaemia and its lipid-lowering mechanism of action. However, the cohort of participants who underwent amputations were more likely to have had previous cardiovascular disease (e.g. angina, myocardial infarction), longer duration of diabetes and had baseline neuropathy.Fenofibrate has an off-label use as an added therapy of high blood uric acid levels in people who have gout.It is used in addition to diet to reduce elevated low-density lipoprotein cholesterol (LDL), total cholesterol, triglycerides (TG), and apolipoprotein B (apo B), and to increase high-density lipoprotein cholesterol (HDL) in adults with primary hypercholesterolemia or mixed dyslipidemia. Severe hypertriglyceridemia type IV or V
It is used in tandem with diet for treatment of adults with severe hypertriglyceridemia.
Recurrent pyogenic cholangitis (RPC), also known as Hong Kong disease, Oriental cholangitis, and Oriental infestational cholangitis, is a chronic infection characterized by recurrent bouts of bacterial cholangitis with primary hepatolithiasis. It is exclusive to people who live or have lived in southeast Asia. Presentation
Presentation can be atypical and without pain or fever, especially in the elderly. Positive symptoms include biliary colic, acute pancreatitis, obstructive jaundice and less commonly, liver enlargement and abnormal liver function tests. Additional complications in the acute setting include ascending cholangitis, gallbladder empyema, clotting within the hepatic and portal veins, sepsis and death.Chronic biliary obstruction may cause jaundice, itchiness, liver abscesses, and cirrhosis, particularly at the left lobe segment 3, and can eventually lead to intraductal papillary mucinous neoplasm or cholangiocarcinoma. Pathogenesis
With RPC, the gallstones found within the biliary system are made of calcium bilirubinate or pigmented calcium. Calcium bilirubinate stones are prevalent in Asia and very rare in Europe and the United States. They tend to be friable concretions of various shapes and sizes within the biliary tree, and their associated bile is often muddy in consistency and contains numerous fine particles of calcium bilirubinate as well. This differs greatly from cholesterol stones, which are common in Europe and the United States. The formation of calcium bilirubinate stones in RPC has been attributed to a high incidence of infection with Escherichia coli in bile. In humans, the majority of bilirubin is excreted in the bile as bilirubin glucuronide.Hepatolithiasis is associated with Clonorchis sinensis and Ascaris lumbricoides infestation of the liver.
