Liu YL, Wang SM, Lin HH, Wang IK, Kuo HL, Yang YF, Liu JH, Chou CY, Yeh HC, Ting IW, Tsai CA, Huang CC: The relationship between chronic hepatitis B infection and bone mineral, metabolism in peritoneal dialysis patients. Clin Nephrol. 2009 Jul;72(1):15-20.
OBJECTIVE: Abnormality of bone mineral metabolism is a common complication in chronic liver disease and/or chronic renal disease patients. We designed this study to evaluate the relationship between chronic hepatitis B infection and bone mineral metabolism in peritoneal dialysis patients. PATIENTS AND METHODS: Serum calcium [adj], phosphorus, calcium and phosphorus product (Ca x P), along with intact parathyroid hormone (iPTH) levels were compared in peritoneal dialysis patients with and without chronic hepatitis B infection. RESULTS: A total of 220 patients (142 female, 78 male) with a mean age of 56.30 +/- 14.28 (range 19 - 86) years old were recruited, 23 showed chronic hepatitis B infection and 197 showed none. No statistically significant difference in serum calcium [adj] levels (9.90 +/- 0.85 mg/dl vs. 10.08 +/- 0.80 mg/dl, p = 0.354), phosphorus levels (5.26 +/- 1.58 mg/dl vs. 5.21 +/- 1.35 mg/dl, p = 0.879) and calcium and phosphorus product (Ca x P) (52.23 +/- 17.54 mg (2)/dl (2) vs. 52.42 +/- 14.16 mg (2)/dl (2), p = 0.960) between groups with and without chronic hepatitis B infection was observed. Serum iPTH levels were significantly lower in chronic hepatitis B patients (median 143 pg/ml, range 3.42 - 889) than in the control group (median 235 pg/ml, range 3 - 2381) (p = 0.035). As analyzed by multi-variable linear regression, chronic hepatitis B was a predictor of lower serum iPTH levels (beta = -0.271; p = 0.030) after adjustments for age, gender, serum calcium and phosphorus levels and diabetes. CONCLUSION: No significant difference in serum calcium [adj]), phosphorus and calcium and phosphorus product (Ca x P) levels appeared between peritoneal dialysis patients with and without chronic hepatitis B infection. Serum iPTH levels proved to be definitely lower in chronic hepatitis B infection patients. |
