Introduction:  Chronic kidney disease (CKD) is commonly associated with secondary hyperparathyroidism. Elevated phosphorus concentrations and decreased synthesis of active vitamin D (calcitriol) as a direct result of impaired renal function induce a cascade of symptoms, including decreased calcium absorption and increased parathyroid hormone (PTH) secretion. This study aimed to assess the association between calcium levels and PTH levels in patients diagnosed with CKD.

Methods:   A cross-sectional observational study was conducted involving a cohort of 80 individuals diagnosed with CKD who met the established criteria. The statistical tests employed in this study were Pearson's correlation. Statistically significant findings are obtained from these tests when the p-value is below 0.05.

Results: This study demonstrates a correlation between decreased levels of calcium in the blood and increased levels of PTH in persons with impaired kidney function.   In eighty patients with CKD stages 3 to 5, regardless of dialysis status, a clear inverse correlation (-0.328, P = 0.000) was observed between parathyroid hormone and serum calcium levels.

Conclusion: Patients with CKD showed a significant inverse correlation between their blood serum calcium levels and PTH levels.   Hence, it is imperative to assess the concentrations of blood calcium and PTH in individuals with CKD and a glomerular filtration rate below 60 ml/min/1.73 m2.
