Prematurity and Related Biochemical Outcomes: Study of Bone Mineralization and Renal Function Parameters in Preterm Infants

Table 1

Comparison of serum calcium, phosphorus, alkaline phosphatase, creatinine and electrolyte levels at 28–30 weeks and 34–36 weeks (Controls) of gestational age in preterm babies.

S. No	Parameter	Cases (𝑛=25)	Controls (𝑛=25)	𝑃-Value
		28–30 weeks	34–36 weeks
(1)	Serum Calcium (mg/dL)	7.044±1.753	9.284±1.276	<0.001
(2)	Serum Phosphorus (mg/dL)	3.012±0.799	5.256±1.308	<0.001
(3)	Serum Alkaline Phosphatase (IU/L)	625.56±176.28	322.08±80.07	<0.001
(4)	Serum Creatinine (mmol/L)	67.64±7.4	46.31±7.7	<0.001
(5)	Serum Sodium (mmol/L)	136.6±4.1	132.8±3.8	NS
(6)	Serum Potassium (mmol/L)	6.98±0.72	5.36±0.60	<0.01

It is evident from this table that serum calcium and phosphorus level is decreased significantly whereas alkaline phosphatase and creatinine levels are significantly and electrolytes are non-significantly increased at 28–30 weeks as compared to 34–36 weeks of gestational age in preterm babies.
