A double blind, multicentre, placebo controlled trial of lornoxicam in patients with osteoarthritis of the hip and knee.

Lornoxicam is a new non-steroidal anti-inflammatory agent (NSAID) with a similar pharmacological profile to other oxicams and a potency 10 times greater than piroxicam. A multicentre, randomised, double blind, parallel group study was undertaken to compare the efficacy and tolerance of four weeks' treatment with lornoxicam (6 mg once daily, 4 mg twice daily, and 6 mg twice daily) and placebo in patients with osteoarthritis of the hip or knee. A dose related efficacy of lornoxicam was shown by the numbers of patients in each treatment group who withdrew from the trial owing to inadequate symptom relief (12/40 (30%) receiving placebo, 6/40 (15) receiving lornoxicam 6 mg daily, 4/40 (10%) receiving lornoxicam 8 mg daily, and none receiving lornoxicam 12 mg daily). This effect was confirmed by pain relief scores, which were significantly better than placebo during treatment with lornoxicam 8 mg and 12 mg daily, the effect of 12 mg daily being significantly superior to that of 8 mg daily. Similar results were obtained from functional status scores. Mean functional index (Lequesne) scores were significantly greater than placebo only at a daily dose of 12 mg lornoxicam. Lornoxicam was generally well tolerated, though some gastrointestinal side effects were seen as has been reported with other NSAIDs. Laboratory investigations showed no evidence of drug toxicity.

Hip arthropathy in genetic hemochromatosis. Radiographic and histologic features.

Genetic hemochromatosis, a disorder of iron metabolism, results in the deposition of massive amounts of iron in the tissues. Arthropathy is one of a number of clinical features associated with the disease. Characteristic radiographic features in the wrist and hand have been reported, and an increased incidence of severe hip disease has been observed. In this study, hip radiographs of 112 patients with genetic hemochromatosis and arthritis were reviewed, and histologic examination of 2 femoral heads was performed. Twenty-eight of the 112 patients (25%) had evidence of arthritis of the hip joint. In 23 (82%) of the 28 patients, this feature was thought to be associated with osteoarthritis; 2 of these patients had an atypical arthropathy associated with radiolucency of the femoral head and histologic features of atypical stripping of the cartilage from the subchondral bone. These atypical features were not thought to be due to avascular necrosis, pyrophosphate-associated arthropathy, apatite-associated deposition arthritis, or osteoarthritis, but may be typical of genetic hemochromatosis and possibly the result of increased susceptibility to shearing forces at the bone-cartilage interface. In 5 of the 28 patients (18%), chondrocalcinosis was the sole abnormal finding on radiography. Ten of the 28 patients eventually required hip surgery, which confirms the severity of the hip disease associated with genetic hemochromatosis.

Studies on the frequency and pathogenesis of liver involvement in rheumatoid arthritis.

A systematic prospective survey of 100 outpatients with rheumatoid arthritis revealed that 45 had biochemical evidence of liver disease. In most cases this was due to increases in total serum alkaline phosphatase (ALP) and/or gammaglutamyl transpeptidase (GGT). Examination of serum ALP isoenzyme profiles in 50 of the patients showed that the liver isoenzyme was the sole or major component in 44 patients, including many with normal total ALP levels. 18% had raised serum liver ALP together with raised GGT, suggestive of an underlying hepatobiliary lesion. No correlation could be detected between raised serum levels of liver enzymes and the age or sex of the patient, duration or severity of arthritis, and drug or alcohol history. However, there was a significant correlation between raised serum ALP and lacrimal or salivary gland dysfunction. It is suggested that immunological mechanisms may be involved in the development of hepatic abnormalities in rheumatoid arthritis.

Indoprofen and naproxen in the treatment of rheumatoid arthritis: a clinical trial.

Thirty-six patients suffering from rheumatoid arthritis took part in a double-blind crossover trial, in which they received either indoprofen 800 mg/day, naproxen 500 mg/day, or a matching placebo. Indoprofen was shown to be significantly superior as an analgesic and in improving grip strength and the patients preferred it. Adverse effects were comparable, although indigestion was seen slightly more often during indoprofen treatment. Indoprofen is therefore at least as effective as existing anti-inflammatory drugs in rheumatoid arthritis and seems to be better tolerated.

Rheumatic disorders in primary biliary cirrhosis.

Eighty-three patients with primary biliary cirrhosis were investigated to determine the prevalence of rheumatic disorders. 14 had scleroderma, which tended to be mild but in several patients produced severe systemic manifestations. The CRST syndrome (calcinosis, Raynaud's phenomenon, sclerodactyly, telangiectasia) was only identified twice. There was an increased incidence of HLA A1+B8 in those patients with scleroderma. As well as those with scleroderma, 4 patients had a destructive arthropathy resembling avascular necrosis. 4 patients had an inflammatory arthritis, without specific features, but the frequency was no greater than might be expected in the general population.

Radioisotope scanning using a gamma camera.

Sixteen outpatients with rheumatoid arthritis took part in a placebo controlled double-blind crossover study. In addition to conventional measurements, a radioactive index was measured using a gamma camera that indicated a radioactive count over the measured joints and a comparable area of normal adjacent bone. This index showed poor correlation with other conventional measurements of change in the clinical trial.

Alclofenac and D-penicillamine. Comparative trial in rheumatoid arthritis.

Forty-six patients with rheumatoid arthritis, 22 receiving D-penicillamine and 2j alclofenac, took part in a 6-month single-bind external observer trial to compare the efficacy and toxicity of these drugs in the treatment of severe rheumatoid arthritis. Both drugs were active and similar in their efficacy at 6 months as judged by clinical and laboratory measurements. Penicillamine was active therapeutically by 3 months, one month before alclofenac. 9 patients, 8 on alclofenac and one on D-penicillamine, had to stop treatment because of lack of effect or toxic effects. Skin rashes within the first week of treatment were a major problem with alclofenac and led to 6 withdrawals.

Multi-centre trial of naproxen and phenylbutazone in acute gout.

Naproxen 750 mg as a single dose followed by 250 mg three times daily has been compared with phenylbutazone 200 mg four times daily for 48 hours followed by 200 mg three times daily for the treatment of acute gout in an open study on 41 patients. The drugs were equally effective with few and relatively mild side effects. Naproxen is a useful alternative agent for the treatment of acute gout.

Spinal changes in idiopathic chondrocalcinosis articularis.

The lumbar-spine radiographs of 67 patients with idiopathic chondrocalcinosis articularis were reviewed for disc calcification and other changes. Calcification was present in 21 (31%) of the patients, seen most frequently at the L 2-3 disc space. The 21 patients as a group were significantly older than the 46 patients without disc calcification, and also had a much higher incidence of chondrocalcinosis in peripheral joints. There was no association with back pain or spinal stiffness. The 21 patients with disc calcification included six patients with a destructive peripheral arthropathy, and three of them had destructive changes affecting the lumbar spine. Three patients with a destructive peripheral arthropathy were also included in the group without disc calcification, and one of these had a destructive arthritis of the lumbar spine. For comparison, there was a 55% incidence of spinal chondrocalcinosis in nine patients with primary hyperparathyroidism and peripheral joint chondrocalcinosis, and a 6% incidence in 100 anteroposterior lumbar spine radiograph 'controls', taken before intravenous urography, although in this latter group the changes were minimal and confined to the margin of a single disc in each case.

Familial Felty's syndrome.

A family is described in which the mother and 2 of the 5 children had Felty's syndrome, a pattern of inheritance suggesting a dominant defect and one which has not previously been reported. The family is also of interest in that the other sib had rheumatoid arthritis.
