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.

A study was undertaken to find our the biological profile of bone symptomatology of decompensated coxarthrosis and gonarthrosis. In a group of 77 patients and in 48 individual patients the levels of calcium, phosphorus, hydroxyproline and nitrogen were studied for four successive days. Calcium was administered by the intravenous route on the third day (186 mg). The results were compared to 16 healthy controls. Analysis was made with reference to the differences in sex, age, stature and anabolic therapy. The products eliminated were referred in absolute amounts to the body surface and to the period of 1 minute. 91 patients and 17 healthy controls were subjected to a provoked hypercalciuria test. Five patients were followed up in a 47Ca kinetic study and its result was compared to the content of Ca/P and P/Ca in serum and urine found in the same patients and in 21 healthy controls. The biological profile was also compared to a group of patients with gonarthrosis and varose deformity and to 127 patients with inflammatory joint diseases. From the results it is assumed that in women with decompensated coxarthrosis and gonarthrosis the syndrome of disease is a bone manifestation which affects the mineral bone substrate and particularly its calcium level. Phosphorus and the organic products of bone (nitrogen and hydroxyproline) of these patients are susceptible to intravenous administration of calcium. In women the metabolism of collagen appears to be more active than that seen in controls, and tends to resemble that of phosphorus. With its lower activity calcium tends to relate to noncollagenic products, such as osseomucoid (glycoprotein, proteoglycan) and osseoalbumoid. In accord with the findings, the patients show a higher miscible pool of calcium (47Ca), and its lower elimination (in urine and stools) and lower accretion to bone. There are a number of factors (sex, stature, age, clinical compensation of disease) that must be taken into consideration when evaluating the results.
