Pain threshold was measured using a pressure algometer in 126 subjects, of whom 54 were females and 72 males. These subjects included 18 males and 18 females with rheumatoid arthritis, 18 males and 18 females with osteoarthritis, 18 males with ankylosing spondylitis, and 18 male and 18 female healthy control volunteers. Six points were studied on each side of the body: 2 cm above the eyebrow on the forehead, lateral aspect of the arm at the insertion of the deltoid muscle, midpoint of the ulna, hypothenar eminence in the palm, midpoint of the quadriceps muscle, and midpoint of the antero-medial aspect of the tibia. None of these points corresponded to the "trigger" points in fibromyalgia. The pain threshold was statistically significantly higher in patients with ankylosing spondylitis than in patients with osteoarthritis, and these in turn were statistically higher than in the normal subjects. Patients with rheumatoid arthritis had significantly lower pain thresholds than the normal subjects. No laterality in pain threshold was identified, but females had in general a lower pain threshold.

The pharmacology, pharmacokinetics, clinical efficacy, adverse effects, and dosage of diclofenac sodium are reviewed. Diclofenac, the first nonsteroidal anti-inflammatory agent (NSAID) to be approved that is a phenylacetic acid derivative, competes with arachidonic acid for binding to cyclo-oxygenase, resulting in decreased formation of prostaglandins. The drug has both analgesic and antipyretic activities. Diclofenac is efficiently absorbed from the gastrointestinal tract; peak plasma concentrations occur 1.5 to 2.0 hours after ingestion in fasting subjects. Even though diclofenac has a relatively short elimination half-life in plasma (1.5 hours), it persists in synovial fluid. The drug is metabolized in the liver and is eliminated by urinary and biliary excretion. In clinical trials, diclofenac was as effective as aspirin, diflunisal, indomethacin, sulindac, ibuprofen, ketoprofen, and naproxen in improving function and reducing pain in patients with rheumatoid arthritis. For treatment of osteoarthritis, diclofenac was equivalent in efficacy to aspirin, diflunisal, indomethacin, sulindac, ibuprofen, ketoprofen, naproxen, flurbiprofen, mefenamic acid, and piroxicam. Diclofenac was as effective as indomethacin or sulindac in treating ankylosing spondylitis. The most frequent adverse effects reported for diclofenac were gastrointestinal, but these effects were fewer and less serious than occurred with aspirin or indomethacin; in addition, diclofenac caused fewer central nervous system reactions than indomethacin. Diclofenac is administered in divided doses with meals. The recommended total daily dosage is 100 to 150 mg (osteoarthritis and ankylosing spondylitis) or 150 to 200 mg (rheumatoid arthritis). Diclofenac is effective, but no more so than other NSAIDs. It is structurally distinct and offers another choice in the treatment of rheumatological conditions.

Serum alkaline phosphatase isoenzymes were determined quantitatively by electrophoresis on cellulose acetate in 168 patients with rheumatic diseases subgrouped for disease activity. Median values of total alkaline phosphatase and bone isoenzyme activity, as well as frequency of patients showing pathological values, increased gradually and significantly corresponding to disease activity in rheumatoid arthritis and ankylosing spondylitis, from 0% in inactive to 90% in very active forms. Bone isoenzyme was much more sensitive than total alkaline phosphatase in moderate disease activity and was also correlated to the number of involved extravertebral joints and pain in ankylosing spondylitis. No correlation was found with stage or duration of disease, age, sex, and erythrocyte sedimentation rate. Additional to bone isoenzyme, liver isoenzymes were elevated in some patients, but with only a weak correlation with disease activity. The intestinal isoenzymes were always normal. We conclude that quantitative determination of serum alkaline phosphatase bone isoenzyme activity is a major indicator for the assessment of disease activity and therapeutic monitoring in rheumatoid arthritis and ankylosing spondylitis.

The derangement of posture in advanced flexion deformity due to ankylosing spondylitis, as well as operative correction procedures are analysed. The "Dorsal Lordosating Spondylodesis", DLS, according to Zielke is introduced. This method of polysegmental correction and transpedicular fixation via USIS implants allows the recreation of a balanced upright posture by restoration of smooth lumbar lordosis. We present results of 173 patients corrected by DLS. Since the total amount of correction is split into 5-7 osteotomy sites, complication rates are substantially lower than in the monosegmental methods. Besides the gain of body height and immediate pain relief, the restoration of a horizontal axis of vision could be achieved. The latter, for all patients the most important feature, was maintained as up to 5 years follow-up's show.

The outcome of total hip replacement (THR) in ankylosing spondylitis (AS) is unclear. Concern has often been voiced by both surgeons and physicians regarding potential reankylosis, mechanical failure and poor function. We present an independent review of the patients' perception of outcome in 150 total hip replacements (138 primary + 12 revisions) in 87 subjects with AS. The mean followup was 7.5 years (1-34 years). Twelve were followed for greater than 15 years and 33 for greater than 10 years. Bilateral replacements were performed in 51 of the 87 patients (59%), 33 (65%) of whom had bilateral surgery within a 12-month period. Failures were early and rare. Twelve of 138 (9%) were revised (8 patients, mean of 3.6 years postoperatively) and 3 of the 12 were rerevisions. Twelve total hip replacements followed for 15 years or more resulted in only 2 failures (same patient: reankylosis) while 3 failed out of 33 followed for 10 years or more. Overall, for the 138 total hip replacements in situ (including the revisions), the patients considered outcome to be good or very good in 86%, while 89% had no (63%) or mild (26%) pain. Mobility was good or very good in 44%. On a scale of 1-5 (very poor to very good) patients followed for up to 5 years scored 4.7, as did those followed for greater than 15 years. Sixty-nine percent of the male recipients under age 60 are at work. Reankylosis occurred in only 1 patient (4 hips). In general the first and second hips replaced had an equally good outcome. The long-term outcome of total hip replacement in AS is very good. The few failures occurred early, and patients were as satisfied with the outcome more than 15 years postoperatively as they were within the first 5 years.

A prospective study analysing the radiological findings of calcaneus bone in ankylosing spondylitis is presented. It includes 43 patients with a relatively low mean age (33.5 years). The morphology of their lesions correlated with disease duration. Abnormal radiological findings were observed in 63% of the patients and in 58% of the radiographs, but in only 3 of 20 normal subjects. Erosive lesions were more frequently found in early stages, whereas sclerotic and proliferative lesions were typical of advanced stages of the disease. Only one patient suffered relevant local pain. No clinico-radiological correlation could be established.

We studied 87 Mexican mestizo patients (82 men and 5 women) with definite ankylosing spondylitis (AS) with particular reference to juvenile and adult onset types. HLA-B27 was present in 32 of 38. Forty-seven patients (54.0%) had onset before the age of 16 years and 40 (46.0%) thereafter. By the end of the 1st year of disease, main features included spinal involvement in 44 (50.6%), peripheral arthropathy in 57 (65.5%) and enthesopathy in 41 (47.1%). Frequency of these increased up to 100.0, 79.3 and 64.4%, respectively, through the course of the disease. Peripheral arthritis and/or enthesopathy occurred in 89.4 and 63.1% of juveniles and 37.5 and 27.5% of adults, respectively, while lumbar pain and/or stiffness occurred in 23.4% of the former and 82.5% of the latter during the first year of disease. Additional findings were high erythrocyte sedimentation rate, anemia and hypergammaglobulinemia. Uveitis was the commonest extraarticular manifestation occurring in 20.6%. Our data suggest that the clinical pattern of AS in our patients was influenced by both age at onset and sex distribution of the disease.

Forty-two sib pairs concordant for ankylosing spondylitis (mean disease duration 20.1 years) were assessed to define the relative role of genetic and environmental factors in determining age and calendar year of disease onset, systemic features, functional outcome and prognosis, and radiologic progression. Twenty-seven pairs were of the same sex (male/male n = 21, female/female n = 6). The correlation coefficient was not significant for age at onset (rs = 0.235), but was much higher for calendar year of onset (rs = 0.702, P less than 0.01). These data were confirmed by two-way analysis of variance: between sibs, the F probability was 0.07 for age at onset (41 degrees of freedom, F ratio 1.6) and was less than 0.001 for calendar year of onset (41 degrees of freedom, F ratio 5.45). Thus, it is suggested that environmental factors play the greater role in the timing of onset. Concordance for the presence or absence of uveitis was only 43%, again suggesting that genetic factors are less significant than the environment. Conversely, genetic factors are more important in influencing prognosis. A disability and pain index revealed that sibs had a closer score than expected by chance alone (P = 0.035); also, the correlation coefficient for blinded radiologic analysis (pelvic and lumbar views) was significant for pairs of sibs (rs = 0.859, P less than 0.01), but was not significant for random pairs of subjects (rs = -0.144). In contrast, within-sib pair and random subject-pair analyses of hip radiographs revealed rs = -0.111 and -0.033, respectively, neither of which was significant.(ABSTRACT TRUNCATED AT 250 WORDS)

A 55-year-old man who has had ankylosing spondylitis for over 20 years developed gradually increasing pain and sensory disorders in the legs, as well as mild foot and toe elevator weakness. There was no evidence of inflammatory activity. Clinical, neurophysiological and neuroradiological examination revealed a cauda equina syndrome as a late complication of ankylosing spondylitis. There is no known causal treatment.

The histopathological characteristic of ankylosing spondylitis (AS) is the presence of chronic enthesitis. Our aim was to develop a clinical measurement of the severity of tenderness over entheses. The scoring system was based on the patients' response to palpation over entheses easily accessible to examination. The enthesis index (EI) correlated with pain (r = 0.67, p less than 0.01) and stiffness (r = 0.46, p less than 0.05) scores. A single, blind, crossover study was conducted to determine the sensitivity of the index to change in clinical state associated with non-steroidal antirheumatic drug therapy and to record the interobserver variability. The index showed significantly lower scores after one week's drug treatment (p less than 0.05). The EI is a convenient, non-invasive measure of disease severity in patients with AS. Potential applications include the assessment of enthesitis in other polyarthritides and a means of distinguishing clinically between severity of enthesitis and synovitis in different types of polyarthritis.
