The new antirheumatic agents, fenoprofen calcium, naproxen, and tolmetin sodium, are effective in the management of rheumatoid arthritis. Their efficacy is comparable, but not superior, to that of aspirin in usual oral doses. These agents also may be useful in degenerative joint disease and ankylosing spondylitis and as analgesics and antipyretics; however, there are insufficient data available to establish their efficacy and dosages for these uses. The incidence of adverse reactions, including gastrointestinal bleeding, is lower with these agents than with aspirin; thus, these drugs may be useful substitutes in patients who cannot tolerate the gastrointestinal effects of aspirin.

An attempt was made to determine whether a relationship exists between ankylosing spondylitis (AS) and hyperparathyroidism (HP). Twenty patients with definite AS, studied for biochemical evidence of HP, did not show consistent abnormalities in serum calcium, phosphorus, alkalinephosphatase, or parathyroid hormone levels or in bone-density measurements. Reviewing roentgenograms of 39 patients with HP showed one patient with sacroiliitis, and one of the 28 hyperparathyroid patients tissue-typed as HLA B27-positive. Both AS and HP are independent entities that have no causative or pathological relationship to each other.

The elimination of calcium, phosphorus, hydroxyproline and nitrogen was studied in 127 patients with inflammatory joint diseases and )6 healthy controls for 4 days. On the third day, 186 mg of calcium was administered intravenously. Provoked hypercalciuria tests were made in 35 males, 116 females with rheumatiod arthritis (RA), 18 males with ankylosing spondylitis (ASp), 8 postinfectious arthritis (PA) and 18 healthy controls (C). In 120 patients comparison was made between the ratios of eliminated P/hydroxyproline, Ca/hydroxyproline and P/Ca with regards to the results obtained in healthy controls. The kinetics of 47Ca were studied in 7 males with ASp and 4 C. The ratios Ca/P in serum and P/Ca in urine were studied in the same patients and compared with 21 C. The results show that the bone symptomatology of PA manifests itself by elimination of elevated amounts of all of the indicators studied, especially phosphorus. In RA there may be considerable oscillations of flow of urine due to the perspiration of patients. RA differs from decompensated coxarthrosis and gonarthrosis in that the patients eliminate significantly less calcium and phosphorus. Corticosteroids stimulate the elimination of hydroxyproline. Younger patients with RA (25-44) show changes compatible with osteoporosis, older females (45-64) display changes similar to those seen in osteomalacia, the oldest female patient (65-84) appear to have insufficient binding capacity for calcium. The hyposthesis is proposed that at the disease onset RA is characterized by an extremely marked syndrome of osteopathy. ASp is characterized by significantly reduced elimination of hydraxyproline, higher metabolic pool of calcium, lower elimination of calcium in urine and faeces and lower accretion to bone.

Neutrophil Fc gamma receptor (Fc gamma R) signalling responses were compared in healthy subjects, patients with definite rheumatoid arthritis (RA), ankylosing spondylitis, and osteoarthritis. The patients with A were subdivided into those with active synovitis and those with quiescent disease. Basal intracellular calcium ion concentrations in patients with inactive RA were significantly higher than in control subjects, which in turn were greater than in patients with active RA. Transient cytosolic calcium ion fluxes were observed after binding Fc gamma RII or Fc gamma RIII with specific monoclonal antibodies and cross linking with the F(ab')2 fragment of antimouse IgG. Response times were significantly faster for Fc gamma RII than for Fc gamma RIII. Peak concentrations of intracellular calcium ions after neutrophil stimulation were comparable for Fc gamma RII and RIII in healthy subjects. Neutrophils in patients with ankylosing spondylitis and osteoarthritis responded to Fc gamma R triggering, but in the group with active RA fluxes of calcium ions were severely depressed. Neutrophils isolated from patients with RA with quiescent disease showed exaggerated responses when compared with controls. Expression of all three Fc gamma R types on neutrophils from patients with active RA, as measured by monoclonal antibody binding, was comparable with control cells. Impairment of neutrophil Fc gamma R cytosolic signalling in active RA could reflect a receptor signalling defect with potential effects on Fc mediated functions, or a fundamental defect in calcium ion homeostasis within these cells.

Patients with severe ankylosing spondylitis of long duration often have spinal osteoporosis secondary to ankylosis and immobility. Bone mineral density of defined regions of the lumbar spine, femoral neck, and carpus was measured in 25 men who met accepted diagnostic criteria for ankylosing spondylitis but had early disease, with normal mobility and no, or very minor, radiological evidence of lumbar spine involvement. Compared with age-matched male controls, patients with ankylosing spondylitis had a significantly lower hydroxyapatite density in the lumbar spine (mean [SD] 0.82 g/cm2 [0.12] vs 0.91 g/cm2 [0.11]) and in the femoral neck (0.83 g/cm2 [0.11] vs 0.92 g/cm2 [0.11]). There was no significant difference in carpal bone mineralisation density. The pattern of bone loss in these patients indicates early loss of trabecular bone in ankylosing spondylitis, possibly from a systemic cause, but biochemical indices of calcium turnover were similar in patients and controls.

A patient with AA amyloidosis secondary to ankylosing spondylitis showed intense liver uptake of Tc-99m MDP on bone imaging. The biopsy showed hepatic amyloid deposition. A repeat bone scan with Tc-99m MDP 1 year later was negative, although the clinical signs and liver function tests of the patient had not changed. A mechanism might exist, other than the affinity of amyloid to calcium, which would explain the extraosseous uptake of pyrophosphates and diphosphonates in organs and soft tissues affected by systemic amyloidosis.

The oxidative metabolism and chemotaxis of polymorphonuclear leukocytes (PMNs) collected from patients with ankylosing spondylitis and healthy subjects were studied in parallel. The responses to opsonized zymosan were significantly lowered considering oxygen consumption and release of superoxide anions, whereas no modification of these parameters to phorbol myristate acetate and calcium ionophore (A 23187) stimulations were observed. A seric factor was not involved but the characterization of a specific intrinsic abnormality of the PMNs needs further investigations. PMN chemotaxis, assessed by two methods performed in parallel, remained unchanged.

Five anatomic specimens were studied in an attempt to visualize by high-resolution computed tomography (HRCT) the ligamentous bands of the costotransverse and costovertebral joints. HRCT-anatomic comparison is presented to relate the CT views to the anatomic structures. The authors demonstrate that axial, sagittal and, to a lesser extent, coronal HRCT views perfectly outline the ligamentous structures, although these are flattened, short, deep and free from calcium deposit. The method may be valuable in disease states such as ankylosing spondylitis.

Subjectively healthy HLA-B27 positive 1st degree relatives (n = 14) of patients with ankylosing spondylitis (AS) were investigated concerning the mass fraction of calcium (Ca), magnesium (Mg), manganese (Mn), iron (Fe), zinc (Zn), strontium (Sr) and copper (Cu) in isolated blood cells using the nuclear microprobe technique. No relative had laboratory signs of inflammatory disease defined by acute phase plasma proteins. An accumulation of Mg, Ca, Mn and Fe was found in granulocytes compared with healthy controls. In platelets there was an accumulation of Fe and a reduction of the Cu content. In erythrocytes Ca was accumulated and the levels of Mg, Mn and Cu were reduced compared with the controls. Five of the relatives had radiological signs of sacroiliitis and 1 of these had sacroiliac tenderness. Relatives with and without radiological sacroiliitis showed no differences in the cellular metal amounts. When the alterations were compared with those previously found in patients with AS, a striking similarity was noted, although the changes were quantitatively less pronounced. In contrast B27 negative 1st degree relatives (n = 11) had normal mineral amounts in their cells. However, it seems less likely that altered metal handling could play a primary role for the disease susceptibility linked to HLA-B27 since B27 positive healthy controls (n = 12) without AS in the family had normal cellular stores of the measured elements. Rather our findings indicate that redistribution of cellular metals is an extremely sensitive marker of an inflammatory process not evident by clinical symptoms or increase of acute phase plasma proteins.

The mechanism of joint destruction in rheumatic diseases is a complex and not fully known phenomenon in which many factors probably take part. The hormones which regulate the bone metabolism may be engaged in this process. In this study the serum level of the parathyroid hormone was correlated with the degree of joint destruction observed in rheumatoid arthritis, ankylosing spondylitis and osteoarthritis. Besides the degree of joint changes (radiologic aspects) the extension of the pathological process and duration of disease were also considered and the serum and urine level of calcium and phosphorus was analyzed. Similar patterns of the parameter investigated were observed in the rheumatic diseases studied and in healthy persons.
