PREVALENCE OF HYPOCALCAEMIA IN A SELECTED POPULATION IN KANO: CALL FOR METABOLOMICS AND GENETIC PROFILING FOR RISK PREDICTION.

Introduction: Severe acute symptomatic hypocalcemia, requiring emergency medical intervention, is a significant but poorly understood condition with high morbidity. In our setting, patients present to emergency rooms with painful carpo-pedal spasms that last for several hours, sometimes mimicking seizure disorders. Metabolomics and genetic profiling are innovative approaches that pinpoint molecular and genetic determinants of hypocalcemia risk which can be adopted to guide treatment in our population.

Objective: To determine the prevalence of hypocalcemia in urban Kano as a preliminary step towards identifying key risk factors.

Methods: We obtained retrospective data from patients who presented to a tertiary hospital between January and December 2023. Serum calcium levels were measured on Abbott Architect c4000 autoanalyzer. We analyzed data using R statistical software (version 4.3.2). Chi-square tests were used to assess significant differences (p < 0.05).

Results: A total of 1,270 samples were analyzed, consisting of 59.3% (n = 753) males, their mean age was 36.2 ± 4 years. Mean serum calcium levels were 2.05 ± 0.34 mmol/L to 2.11 ± 1.00 mmol/L. Overall prevalence of hypocalcemia (serum calcium < 2.2 mmol/L) was 52.2%. Females exhibited a significantly higher prevalence (58.8%) compared to males (p = 0.03). The highest prevalence was observed in the 40-59-year age group (p < 0.01).

Conclusion: Hypocalcemia is highly prevalent in our population emphasizing the need for innovative approaches to better understand the genetic predictors, enable early intervention and prevent the long-term complications. These findings also provide a foundation for future multicenter studies and could inform public health policies targeting at risk groups.
