RESUMO
Protein-bound homocyst(e)ine was measured in the plasma of 38 nonhomocystinuric patients with rheumatoid arthritis. Nineteen of them were treated orally with D-penicillamine 100-1,500 mg/d for a period of one month to 15 years. For these patients, the mean +/- standard deviation level of plasma protein-bound homocyst(e)ine was 1.95 +/- 1.07 nmol/mL. In contrast, the mean plasma level of protein-bound homocyst(e)ine was 4.72 +/- 1.11 nmol/mL in the 19 patients who had not been treated with oral D-penicillamine. There was a statistically significant difference (P less than .0001) in the plasma protein-bound homocyst(e)ine concentrations between patients with and without oral D-penicillamine therapy. Thus, it may be speculated that oral D-penicillamine may be beneficial in protecting patients from the development of thromboembolism and arteriosclerosis.

Pain properties of 50 fibromyalgia patients were examined and compared with pain properties of 50 rheumatoid arthritis patients. In both fibromyalgia and rheumatoid arthritis, pain was bilateral, involved multiple sites, and was of equal intensity (60.8 versus 58.7, respectively, on a scale of 100). Fibromyalgia pain, however, was less localized to the joints and suggested greater spatial diffusion. It involved more kinds of pain experiences (radiating, steady, spreading, spasms, gnawing, unlocalized, pricking, crushing, shooting, pressing, splitting, cramping, nagging, and pins and needles), and was dispersed over larger areas of the body. The anatomic sites best for discrimination between patients with fibromyalgia and patients with rheumatoid arthritis were the lower back, thigh, abdomen, head, and hips for fibromyalgia, and wrist, foot, and fingers for rheumatoid arthritis. The traditional clinical description of aching and stiffness does not appear to accurately describe the complexity of the fibromyalgia pain syndrome.

Thirty patients with fibrositis and 2 control groups, one of rheumatoid arthritis patients and the other of arthritis patients with other than rheumatoid arthritis, were compared on the basis of the Minnesota Multiphasic Personality Inventory (MMPI) to assess the role of psychologic factors in fibrositis. Patients with fibrositis differed in both elevation and variability in their MMPI profiles, indicating that they were more psychologically disturbed than patients with rheumatoid or other types of arthritis. The fact that almost all of the fibrositis patients' MMPI scales were higher suggests that we might be dealing with a number of different psychologic disturbances that have stiffness and musculoskeletal pain as principal and common symptoms.
