Children with haematological malignancies such as acute lymphoblastic leukaemia (ALL) may have alteration of bone mineral metabolism therefore increased risk for osteopenia and osteoporosis.The purpose of this study was to examine the alterations of bone mineral metabolism in two groups of children (n=42) according to immunophenotyping (B-cell type, T-cell type) both quantitative (bone mineral density z-scores) and qualitative (serum osteocalcin - OC and carboxyl-terminal telopeptide of human type I collagen - ICTP) during diagnosis (T=0), after the intensified chemotherapy period (T=0.5) and the consolidation period (T=1).According to our results 15 patients had osteopenia and 1 child developed osteoporosis at T=0.5 and 13 patients had osteopenia at T=1. Mean BMD z-score was significantly decreased in both groups during chemotherapy and especially statistically significant decline of T-cell type ALL group compared with B-cell type ALL patients. OC mean level remains in low levels for both groups reaching in plateau during chemotherapy and ICTP level was increased in T-cell type ALL group of patients compared with B-cell type in both periods of chemotherapy.It seems that not only the combination of chemotherapeutic agents but also the cell lineage of ALL are important parameters of altering bone mineral metabolism. |
