[Q]: Abstract: Studies in patients on dialysis have shown that aluminum (Al) accumulation in bone plays a major role in the pathogenesis of osteomalacia. It has been suggested that deferoxamine (DFO) may be beneficial in the treatment of aluminum-induced osteomalacia. The present studies were performed in four groups of uremic rats to determine if DFO and/or discontinuation of Al administration have an effect on bone histomorphometry and blood chemistries. The groups were: 1) uremic control 2) aluminum (0.75 to 1.0 mg/rat i.p., five times a week for twelve weeks): 3) aluminum + DFO, after twelve weeks Al was discontinued and the rats received DFO (75 mg/rat two times a week for nine weeks); 4) aluminum + time, after twelve weeks Al was discontinued and the rats were sacrificed after nine weeks. High levels of Al in serum and bone and low levels of PTH were seen in rats receiving Al. Bone histology revealed Al at the mineralization front, abnormal tetracycline uptake, and an increase in osteoid. DFO treatment did not significantly change the level of Al in bone, however both DFO treatment and discontinuation of Al reversed towards normal the above described lesions. In conclusion, these studies suggest that DFO and/or discontinuation of Al administration to rats with approximately 30% of renal function greatly improve aluminum-induced osteomalacia.

[Q]: Abstract: Non-excretor cirrhotic patients, defined by their inability to normally excrete a standard water load, display variable responses to head-out water immersion. The hemodynamic, hormonal, and renal functional status of fifteen such patients were analyzed relative to water excretion during head-out water immersion. Group 1 patients (N = 7) all excreted less than 40% of the water load during immersion, whereas excretion was greater than 40% in all eight patients in Group 2. Group 1 patients, when compared with Group 2, had more ascites, more diuretic resistance, lower serum sodium concentration (125 +/- 2 vs. 130 +/- 1 mEq/liter, P less than 0.05), and more impaired baseline water excretion (12.9 +/- 1.2 vs. 35.9 +/- 5.9% of water load in 5 hr, P less than 0.005). Systemic hemodynamic responses to water immersion were similar in both groups. Glomerular filtration rate and renal plasma flow were significantly more impaired in Group 1 patients (inulin clearance 28 +/- 6 vs. 62 +/- 9 ml/min/1.73 m2, P less than 0.05; para-aminohippurate clearance 212 +/- 35 vs. 357 +/- 37 ml/min, P less than 0.05). Concentrations of plasma vasopressin (1.7 +/- 0.5 vs. 0.8 +/- 0.1 pg/ml, P less than 0.05), renin (8.6 +/- 1.7 vs. 3.8 +/- 0.9 ng/ml/hr, P less than 0.05), aldosterone (82 +/- 14 vs. 39 +/- 10 ng/dl, P less than 0.05) and norepinephrine (1155 +/- 183 vs. 603 +/- 126 pg/ml, P less than 0.05) were all significantly higher in Group 1 than Group 2 patients during water immersion.(ABSTRACT TRUNCATED AT 250 WORDS)

[Q]: Abstract: Although osteoarthritis (OA) generally is considered a disorder of mechanical origin, the common occurrence of chronic mononuclear cell infiltrates in the synovium in conjunction with immunofluorescent evidence for immune-reactant products in cartilage of surgical case specimens (knees, hips, and peripheral joints) has suggested the local involvement of immune processes in the arthritis. Further, the findings of polyarthropathy in the majority of these cases have indicated the propensity for a systemic disorder. Wide variations were noted in both synovial and cartilage immune changes, quite different to those found in rheumatoid arthritis, along with the frequent asymptomatology of the many joints involved. These features, with and without other causative factors, suggest that immune reactions of local and/or systemic origin occur at times in a population at risk for joint degradation.
