ABSTRACT
Background: In 2016, 6.3 million cases of PTB were reported by WHO. Magnesium is extremely essential for life and is present as intracellular ion in all living cells and tissues¹. Some workers have found serum Magnesium level to decrease in cases of PTB, which rises towards normal with specific treatment. Objectives: 1. To estimate and compare serum Magnesium levels in cases and controls 2. To measure correlation between Magnesium levels and severity of PTB Materials and Methods: This was a prospective case control study, conducted on 30 PTB patients and 30 controls who met the inclusion and exclusion criteria of the study. This study was done in S.Nijalingappa Medical College, Bagalkot, Karnataka during the period September 2021 to January 2022. All patients were clinically evaluated and underwent relevant investigations. Results: There was significant decrease in Serum Magnesium in cases and more decreased in moderately advanced and far advanced disease. Conclusion: The study concludes that there is significant reduction in Serum Magnesium in PTB and it further decreases as the severity of PTB increases, hence necessitating early treatment of PTB and need for Magnesium supplementation in PTB patients.
