Comparison of auranofin, gold sodium thiomalate, and placebo in the treatment of rheumatoid arthritis. A controlled clinical trial.

A prospective controlled, double-blind multicenter trial compared placebo, auranofin (an orally administered gold complex), and parenteral gold sodium thiomalate (GST) in patients with active rheumatoid arthritis (RA). Of 193 patients who received any treatment, the only important improvement identified for either auranofin or GST was for pain/tenderness scores. When 161 patients who completed 20 weeks of treatment were examined, both auranofin and GST treatments were superior to placebo as measured by improvement in number of painful and/or tender joints, joint pain/tenderness scores, physician's assessment of disease activity, and decrease in erythrocyte sedimentation rate when elevated at entry. GST was superior to placebo in improvement of joint swelling scores, anemia, thrombocytosis, and rheumatoid factor. No drug-related remissions were observed. The only statistically significant advantages of GST over auranofin for efficacy were an increase in hemoglobin concentration and decrease of thrombocytosis with GST. Withdrawals for adverse effects were 5 times more frequent with GST treatment. Thrombocytopenia, proteinuria, elevated liver enzymes, "nitritoid" reactions, and "gold pneumonitis" were observed only in the GST treatment group. These results confirm that both parenteral and oral gold may be effective for the treatment of RA, that GST tends to show greater efficacy than auranofin, and that auranofin has fewer significant adverse effects than GST. However, long-term benefits, tolerability, and safety cannot be inferred from this study.

Rheumatoid vasculitis of the colon presenting as pancolitis.

This report describes a patient with pancolitis resulting from rheumatoid vasculitis. Corticosteroid treatment reduced colonic inflammation but colectomy was required to control hemorrhage. The case illustrates the need to recognize colitis as a manifestation of rheumatoid vasculitis so that new treatment modalities may be employed to achieve a more successful medical management. The appearance of discrete colonic ulcerations following corticosteroid treatment of pancolitis in patients with rheumatoid arthritis should further suggest the diagnosis of intestinal vasculitis.

Spontaneous nasal septal perforation in patients with rheumatoid arthritis.

Nasal septal perforation is known to be associated with various traumatic and disease states, yet spontaneous nasal septal perforation (SNSP) is relatively rare. SNSP has been reported in three patients with seropositive rheumatoid arthritis (RA) and we report an additional seven patients with SNSP and RA, four of whom were seronegative and none of whom had Raynaud's, in contrast to those reported previously. Manifestations of overt infectious, neoplastic or granulomatous disease have not been found in our seven patients over several years of close follow-up. We have identified no obvious pathogenesis or specific etiology for SNSP. We suggest that SNSP may represent an unusual manifestation of RA previously not well recognized.

Familial brachydactyly and chondrocalcinosis. Report of a patient, pedigree and review of the literature.

Familial brachydactyly has been recognized for many years but no published accounts report associated chondrocalcinosis. We recently evaluated such a patient and report the occurrence of brachydactyly in 4 generations of his kindred. The pattern of brachydactyly in this pedigree suggest autosomal dominant inheritance that is the mode of inheritance in most kindreds. The prepositus with chondrocalcinosis has longstanding arthralgias of both knees as does at least one other close relative who also has brachydactyly. The possibility that chondrocalcinosis may be part of the syndrome is suggested but awaits further clarification.

Clinical manifestations of synovial cysts.

Although synovial cysts are most commonly associated with rheumatoid arthritis and osteoarthritis, they may occur in many other conditions. The clinical manifestations of these cysts are numerous and may result from pressure, dissection or acute rupture. Vascular phenomena occur when popliteal cysts compress vessels, and result in venous stasis with subsequent lower extremity edema or thrombophlebitis. Rarely, popliteal cysts may cause arterial compromise with intermittent claudication. Neurological sequelae include pain, paresthesia, sensory loss, and muscle weakness or atrophy. When synovial cysts occur as mass lesions they may mimic popliteal aneurysms or hematomas, adenopathy, tumors or even inguinal hernias. Cutaneous joint fistulas, septic arthritis or osteomyelitis, and spinal cord and bladder compression are examples of other infrequent complications. Awareness of the heterogeneous manifestations of synovial cysts may enable clinicians to avoid unnecessary diagnostic studies and delay in appropriate management. Arthrography remains the definitive diagnostic procedure of choice, although ultrasound testing may be useful.

Rheumatology. What should students know?

The majority of patients with rheumatologic problems are seen and followed by nonrheumatologists. Of concern is the perception that a significant number of United States medical schools do not have adequate teaching programs in the rheumatic diseases. Two thousand two hundred and seventy practicing physicians, trainees, and medical students were surveyed in the Intermountain West to determine what they think undergraduate medical students should learn about rheumatology. Most respondents felt that common diseases and problems should be emphasized and that basic skills in history taking and physical examination are more important than disease related information.

Endotoxin toxicity in rats with 6-sulfanilamidoindazole arthritis.

Seven oral administrations of 6-sulfanilamidoindazole (6-SAI) to 10- to 12-month-old rats sensitized the animals to endotoxin, with dosages as small as 2.5 microgram causing death in 80% of animals. Endotoxin in a dosage of 3,000 microgram was not lethal for nonmedicated control animals. 6-SAI-treated 1-month-old rats were not as sensitive to endotoxin as aged animals. The sulfonamide-induced sensitivity to endotoxin could not be passively transferred and could not be explained by blockade of the reticuloendothelial system or impairment of endotoxin detoxification. 6-SAI administration was associated with both depletion of liver glycogen and lowering of blood glucose concentration without changes in blood lactic acid concentration. Disseminated intravascular coagulation is believed to be involved in the pathogenesis of shock and death as evidenced by: (i) concomitant decreases in plasma fibrinogen concentration and elevations in fibrin degradation products after endotoxin challenge; (ii) protection against lethal actions of endotoxin by pretreatment with heparin. Treatment of 6-SAI-medicated rats with glucocorticoids before endotoxin challenge protected the animals against lethal doses of endotoxin and prevented deposition of fibrin thrombi in the glomerular capillaries.

Nodular nonsuppurative panniculitis associated with jejunoileal bypass surgery.

A 32-year-old woman underwent jejunoileal bypass surgery for morbid obesity. Her postoperative course was marked with many of the complications of this type of surgery. In addition, tender, erythematous nodules developed on her legs and abdomen that were grossly and microscopically consistent with nodular nonsuppurative panniculitis. She did not have any condition or disease previously reported to be associated with nodular nonsuppurative inflammation. The nodular panniculitis in this patient appears to be a new complication of small-bowel bypass surgery.

Joint pain of recent onset.

A joint pain of recent onset is a common and often challenging problem to the family physician. The many etiologies of acute arthritis require a systematic approach to a careful definition of the problem which is essential to safe and effective therapy. The proper evaluation of joint pain of recent onset requires a detailed history and physical examination as well as a rationally selected battery of laboratory studies. This paper provides the busy physician with a specific approach to the diagnosis of acute joint pain as the basis for precise management.
