The nocebo effect, the inverse of the placebo effect, is a well-established phenomenon that is under-appreciated in cardiovascular medicine. It refers to adverse events, usually purely subjective, that result from expectations of harm from a drug, placebo, other therapeutic intervention or a nonmedical situation. ⋯ Statin-intolerant patients usually tolerate statins under double-blind conditions, indicating that the intolerance has little if any pharmacological basis. Known techniques for minimizing the nocebo effect can be applied to the prevention and management of statin intolerance.

Homozygous familial hypercholesterolemia is a rare clinical phenotype with a variable expression, which is characterized by extremely elevated plasma low-density lipoprotein (LDL), tendon and skin xanthomas, and a progressive atherosclerosis. In 95% of patients, homozygous familial hypercholesterolemia is due to mutations in low-density lipoprotein receptor (LDLR) gene, which abolish (receptor-negative) or greatly reduce (receptor-defective) LDLR function. ⋯ We report a rare event of 4 siblings found to be compound heterozygotes for 2 LDLR gene mutations but showing a different phenotype severity. The less severely affected siblings were carriers of a rare apoB missense variant.

To evaluate patient characteristics, treatment patterns, comorbidities, and risk factors associated with the development of acute pancreatitis (AP) in patients with severe hypertriglyceridemia (HTG) in an integrated health care delivery system. ⋯ Patients with severe HTG are at a higher risk of developing AP. A number of comorbidities, risk factors, and baseline TG levels are associated with an increased incidence of AP. Patients with severe HTG are underdiagnosed, undertreated and are nonadherent to their index lipid therapy. There is a need to better define optimal approaches to treating severe HTG so as to reduce the incidence of AP. Economic studies are also needed to evaluate the burden of AP on various health care systems.
