An endoscopic study of gastroduodenal lesions induced by nonsteroidal anti-inflammatory drugs.

Rheumatoid arthritis (RA) and osteoarthritis (OA) are frequently treated with nonsteroidal anti-inflammatory drugs (NSAIDs). Although NSAIDs are an effective therapy for the pain and inflammation of arthritis, they are associated with serious side effects, particularly ulceration, bleeding, and perforation of the gastrointestinal (GI) tract. In this study, 1826 OA or RA patients who either had been taking NSAIDS for > or =6 months or had been unable to tolerate continuous NSAID use because of adverse GI symptoms or suspected NSAID-related gastroduodenal lesions were examined endoscopically for gastroduodenal lesions and ulcers. At the same time, the patients were asked to rate the severity of any GI symptoms they had been experiencing. Of the total number of patients studied, 817 (44.7%) were OA patients with a mean (+/- SD) age of 55.8+/-12.9 years, and 1009 (55.3%) were RA patients with a mean age of 53.1+/-13.1 years. Clinically significant gastroduodenal lesions were found in 37.1% of patients (n = 678); of these, 24.0% (n = 439) had ulcers. Gastric ulcers were more frequent than duodenal ulcers (14.8% vs 10.2% of patients; P < 0.05), and most gastric ulcers (72.0%) were found in the antrum of the stomach. The prevalence of gastroduodenal ulcers increased with age (P < 0.001), duration of OA (P < 0.001), and duration of current NSAID use (P = 0.019). The prevalence of gastroduodenal ulcers in patients taking NSAIDs for <1 year was 13.8%, compared with a nearly twofold higher prevalence (25.9%) in patients taking NSAIDs for periods of > or =1 year and up to 15 years. The prevalence of gastric ulcers was 32.6% in patients with a history of gastric ulcer but only 13.5% in patients with no GI history (previous gastric ulcer, duodenal ulcer, or upper GI hemorrhage). No relationship was found between the prevalence of gastroduodenal ulcers and sex (men, 22.4%; women, 24.9%) or prevalence of gastroduodenal ulcers and type of arthritic disease (RA, 23.6%; OA, 24.5%). The prevalence of gastroduodenal ulcers increased with the severity of GI symptoms (P = 0.007). These results provide further endoscopic confirmation of the association between NSAID use and gastroduodenal lesions and ulcers and support the contention that safer treatment alternatives to conventional NSAIDs are required.

Intra-articular orgotein in osteoarthritis of the knee: a placebo-controlled efficacy, safety, and dosage comparison.

PURPOSE: Superoxide dismutase (orgotein for injection) has been used in managing osteoarthritis for more than seven years in Europe; however, well-controlled studies to establish an optimum dosage regimen have not been conducted. In this study, three orgotein dose/regimens were compared with placebo in terms of efficacy, safety, and duration of effect in patients with active osteoarthritis of the knee. PATIENTS AND METHODS: A total of 139 patients with osteoarthritis of the knee were enrolled in the study. Nonsteroidal anti-inflammatory agents were withdrawn to induce a flare of disease activity. Patients were then randomly assigned to receive one intra-articular injection of either placebo or orgotein (8 mg to 32 mg) each week for three weeks. Both investigators and patients evaluated disease activity and adverse experiences at a series of follow-up visits for three months. RESULTS: Orgotein was effective in reducing symptoms of osteoarthritis for up to three months after treatment; 16 mg given twice was the most effective and most best-tolerated regimen. Discomfort at the injection site was drug related, although this effect also occurred occasionally after injection of placebo. CONCLUSION: The long-lasting effects of intra-articular superoxide dismutase contribute to a favorable risk-benefit ratio and support the importance of the free-radical anion, superoxide (O2-), in the biochemical pathology of osteoarthritis.

Reiter's disease.

Reiter's disease can no longer be considered a rare and relatively benign syndrome consisting of the clinical triad of urethritis, conjunctivitis and arthritis. It is, in fact, a post-infectious reactive arthritis that belongs to a new group of diseases now called seronegative spondyloarthropathies. These diseases are characterized by an extremely high association with the genetic marker, human leukocyte antigen B27. In its full course, the disease often is incomplete with its initial clinical manifestations and characterized by chronicity and progressive crippling recurrences.

"Ankylosing spondylitis" without sacroiliitis in a woman without the HLA B27 antigen.

An elderly woman with otherwise typical ankylosing spondylitis for 45 years lacked radiologic evidence of sacroiliitis and the HLA B27 antigen. The illness was complicated by renal tuberculosis requiring a left nephrectomy 23 years after the onset of low back pain, and 20 years after an episode of severe iritis. After the eradication of the tuberculosis by surgery and chemotherapy, she has continued to have symptomatic spondylitis. The case seems to be an exception to the rule that sacroiliitis is a sine qua non for ankylosing spondylitis. Women with ankylosing spondylitis tend to have milder disease with an apparently lower frequency of roentgenographic changes in sacroiliac joints.

Ankylosing spondylitis and related diseases: significance of HL-A W27 histocompatibility antigen.

The HL-A W27 tissue antigen provides a laboratory tool that has already been of great use in explaining the clinical relationships and overlaps among the true seronegative arthritides. In addition, the W27 antigen is useful to the clinician in differential diagnosis and is becoming more readily available through various laboratories. Tissue typing can be done with a tube of blood sent to the laboratory. As and its variants are becoming better understood and thus will be better managed as a result of the recent developments in transplantation antigen typing.

Immunoglobulin in clinically uninvolved skin in systemic lupus erythematosus: association with renal disease.

23 of 42, or 55%, of patients with systemic lupus erythematous had immunoglobulin deposits along the epidermal basement membrane of uninvolved skin (positive lupus band test [LBT]). In patients with low serum complement levels, 91% had a positive LBT), as compared with 15% in those with normal complement levels. The LBT was positive in 70% of patients with clinical and laboratory evidence of renal disease, but in only 31% of patients without renal disease. 81% of patients with the more severe histologic forms of lupus nephritis, i.e., proliferative glomerulonephritis and membranous glomerulonephritis, and positive tests, whereas only 23% with mesangial glomerulitis or normal histologic findings were positive. Immunoglobulins of the same class found in the skin were detected in the glomeruli of patients examined by renal biopsy. These results suggest that there is a relationship between the occurrence of immunoglobulin in the epidermal basement membrane and the presence of the more severe forms of lupus nephritis.
