RHEUMATIC MANIFESTATIONS OF HYPERLIPIDEMIA AND ANTIHYPERLIPIDEMIA DRUG-THERAPY

Conflicting data exist with respect to the existence and clinical manifestations of a hyperlipidemic arthropathy. Reasonable evidence supports the existence of a migratory polyarthritis similar to rheumatic fever in patients homozygous for type II hyperlipidemia. Although similar complaints have been described in patients heterozygous for this condition, findings have been inconsistent among various reports. It is posible that high lipid levels are required to induce rheumatic complaints, and these are found predominantly in homozygous patients. Even so, rheumatic syndromes appear to be more attributable to periarthritis because evidence of inflammatory arthritis is largely lacking. In contrast, Achilles tendinitis appears to be associated with heterozygous type II hyperlipidemia and presumably is based on lipid deposits within the tendon. Gout is an accepted association of type IV hyperlipidemia. In addition, oligoarticular symptoms have been described with type IV hyperlipidemia. However, no consistent clinical entity has emerged. Drugs used in the treatment of hyperlipidemia are associated with a variety of rheumatic problems, including proximal myopathy and lupus-like syndromes. The most commonly implicated drugs are the hydroxymethyl-glutaryl-coenzyme A reductase inhibitors and the fibric acid derivatives. © 1993 W.B. Saunders Company. All rights reserved.
