AIM: This study aimed at comparing between bone density using DEXA, serum osteocalcin and urinary DPD in obese and non obese prepubertal children. METHODS: After taking the consent of eighty children they were subjected to: full examination, anthropometric measurements, blood samples were withdrawn to determine serum osteocalcin, Ca, Ph, alkaline phosphatase, and urinary DPD. Bone densities, body composition of the whole body were examined using DEXA. Data were analyzed using SPSS.RESULTS: All anthropometric variables showed significant increase in obese children except for height in comparison to control group. Total mass, lean + BMC, lean, fat, area, BMC, BMD and Z score of the whole body were significantly increased in obese children. Serum calcium showed significant increase while alkaline phosphatase was significantly decreased in obese children. DPD showed no significant difference between obese and non obese children. Significant negative correlation was found between ca, lean, lean + BMC and total mass. Serum alkaline phosphatase showed also a significant negative correlation with (lean + BMC and total mass). Serum osteocalcin showed negative significant correlation with area, BMC, BMD, lean and Z score.CONCLUSION: Obese children showed significant increase in anthropometric and DEXA parameters, increase in serum calcium and significant decrease in serum alkaline phosphatase. Osteocalcin was negatively correlated with most of DEXA results.

Background: Normal cerebral membrane integration is important to maintain the cellular calcium homeostasis. Recent studies have suggested that elevated serum calcium levels at presentation correlates well with the infarct size and severity of stroke.Methods: A total of 73 patients with acute ischemic stroke satisfying inclusion and exclusion criteria were included in the study from November 1st 2017 to April 30th 2019 at a tertiary care centre in Kolar, Karnataka. Serum calcium (total, ionized and albumin corrected calcium) levels were measured at the time of presentation and compared with the infarct size and severity of stroke using NIHSS score (National Institute of Health Stroke Scale).Results: The levels of total calcium, albumin-corrected calcium, and ionized calcium were 9.13±0.89 mg/dL (range: 8.24-10.02), 9.56±0.82 mg/dL (range: 8.74-10.38), and 4.79±0.47 mg/dL (range: 4.3-5.2), respectively. Mean stroke size as measured on the CT scan was 47.38±17.7 cm (range: 21-88). Analysis revealed significant negative correlation between calcium levels (total, corrected, and ionized) and infarct size and severity of stroke.Conclusions: In this study, it was found that there was a statistically significant negative correlation between total, ionized and corrected calcium with the infarct size in patients with ischemic stroke and also the total calcium at presentation and severity of stroke calculated using NIHSS score.

SUMMARY Methods for assay of parathyroid hormone based on an increase in serum calcium concentration, urinary 32P excretion and serum alkaline phosphatase elevation in parathyroidectomized rats have been compared and modifications introduced to improve sensitivity, precision, speed and ease of manipulation. Both the serum calcium and urinary 32P assay gave good precision (mean λ = 0·23 and 0·29, respectively) but by the serum calcium method less than 10 USP units of parathyroid hormone could not be detected, whereas the phosphaturic assay detects as little as 0·5 USP unit. Both assays are simple to perform and each requires only 2 days to complete. They can be combined in a single design using the same animals. Assays based on serum alkaline phosphatase levels in parathyroidectomized rats were not successful since it was impossible to produce a significant alteration in serum alkaline phosphatase by the administration of parathyroid hormone.

The development of bone metastases in cancer can be monitored easily using three markers: 24 h urinary hydroxyproline excretion (HOP) (an index of osteoclastic activity), serum alkaline phosphatase (Alk.Ph.) (an index of osteoblastic activity) and 24 h whole body retention of 99mTc-methylene diphosphonate (WBR%) (an index of bone turnover). To evaluate the effectiveness of this group of bone tumor markers in breast cancer we compared it with the following group of three markers which are commonly used in the monitoring of breast cancer and in the follow-up of advanced disease with or without bone metastases: carcinoembryonic antigen (CEA), tissue polypeptide antigen (TPA) and breast carcinoma antigen (CA 15/3). In 48 patients with bone metastases CEA, TPA and CA 15/3 were shown to be sensitive (79%, 85%, 90% respectively), while HOP, Alk.Ph. and WBR%, which are commonly accepted as reliable markers of bone activity, showed a lower sensitivity (67%, 46%, 75% respectively). These results may be explained by the lack of osteoclastic or osteoblastic (or both) activity at the time of diagnosis. This explanation is supported by the fact that the bone markers HOP, Alk.Ph. and WBR% were found to be more sensitive than the others in the subsequent follow-up study. We conclude that in our study, CEA, TPA and CA 15/3 are at first more sensitive than Alk. Ph., HOP and WBR% but during the follow-up Alk.Ph., HOP and WBR% are possibly both more specific and more sensitive

A case-control cross-sectional study was carried out to observe the changes in serum calcium, albumin and alkaline phosphatase levels of postmenopausal women compared to their premenopausal counterparts. This is to enable us ascertain the relative risk of developing osteoporosis in postmenopausal women in Bangladesh. One hundred and eighteen (118) apparently healthy females (59 premenopausal=control and 59 postmenopausal=case) were selected for the study. The study was carried out in the Department of Biochemistry, Mymensingh Medical College in cooperation with the Department of Gynecology, Mymensingh Medical College Hospital and Community Based Medical College Hospital Bangladesh during the period from January to December 2009. Data were collected through clinical evaluation from pre-selected questionnaires. Fasting venous blood samples were taken for laboratory investigations. Serum calcium and albumin was determined using colorimetric method and enzymatic end point method was used to determine serum alkaline phosphatase levels. Statistical significance of difference between two groups were evaluated by using Student's unpaired 't' test with the help of SPSS software package. The results showed statistically significant decrease in serum calcium and albumin (p<0.01) of menopausal women compared to reproductive age group. The postmenopausal women had significantly higher (p<0.01) concentrations of serum alkaline phosphatase than the premenopausal women with regular menstruation. Therefore, it can be concluded that menopause leads to the increased risk of osteoporosis by decreasing serum calcium and albumin and by increasing alkaline phosphatase levels. The decreased serum calcium and increased alkaline phosphatase levels indicate that menopause is an independent risk factor for developing osteoporosis in women of Bangladesh.

Biochemical changes that had appeared after subtotal parathyroidectomy (PTx) in 26 patients with end-stage renal failure were observed. The volume of excised parathyroid glands was also measured. Serum calcium and inorganic phosphorus levels fell after PTx; only to rise in due course. Serum alkaline phosphatase levels rose after PTx, reaching a peak by the 14th postoperative day. These elevated levels returned to normal range at about three months after PTx. Strong correlation was noted among the degree of postoperative hypocalcemia, and increase in serum alkaline phosphatase, but not between absolute pre or postoperative alkaline phosphatase levels and changes in serum calcium or phosphorus concentrations. Nevertheless, significant correlation was seen between pre-PTx levels of alkaline phosphatase and its short-lived postoperative rise, indicating hastened osteoblastic activity.

Background: Bone is a strong dynamic organ of the endoskeleton playing a vital role in structural integrity envisaging to keep proper shape and maintenance of the body, mineral reservoirs, blood production, coagulation and immunity. Metabolic bone diseases are a heterogeneous group of disorders that interrupt the normal homeostasis of bone formation and resorption. Bone regulates as well as acts as a host for hematopoiesis by providing niche for proliferation and differentiation of hematopoietic cell. Bone is a dynamic tissue but metabolically active as it is being constantly formed (modelling) and reformed (remodelling). Metabolic bone diseases comprise of a broad spectrum of inherited and acquired disorders characterized by abnormalities in calcium metabolism and bone cell physiology- that lead to an altered serum calcium concentration and skeletal failure.Methods: After taking a properly informed written consent and complete history, thorough clinical examination was done and these patients were subjected to radiographic imaging and biochemical analysis.Results: Serum alkaline phosphatase is a good marker in rickets and osteomalacia, ICTP in osteoporosis, pyridinoline, deoxypyridinoline in primary hyperparathyroidism, serum PICP in renal osteodystrophy.Conclusions: In cases of rickets and osteomalacia either decreased or normal values of serum calcium and serum phosphorus were obtained. But the cases pertaining to renal failure with rickets values of serum phosphorous were found to be raised. However, in all cases of rickets and osteomalacia values of serum alkaline phosphatase were also found to be raised.
