Oligo-arthritis and type IV hyperlipoproteinemia.

The increased risk of cardiovascular mortality in patients with inflammatory joint disease indicates a need for routine investigations to detect conventional cardiovascular risk factors. These investigations may provide the classification of the disease. We report a case of oligoarticular arthritis with type IV hyperlipoproteinemia, a condition of which only 15 cases are described in the literature. The patient had oligoarthritis, laboratory signs of severe inflammation, and type IV hyperlipoproteinemia (triglycerides, 24.6 mmol/L; and total cholesterol, 10.7 mmol/L). The clinical and laboratory test abnormalities resolved under fenofibrate therapy.
