BACKGROUND/OBJECTIVES: Magnesium plays a crucial role in immune function, influencing immunoglobulin synthesis, antibody-dependent cytolysis, and other immune processes. In renal transplant patients, magnesium deficiency is primarily induced by calcineurin inhibitor treatment, through the reduction of magnesium transporter proteins in the renal tubules, leading to magnesium loss.
METHODS: To assess the correlation between serum magnesium levels and the long-term outcomes of renal graft and transplant recipients, we conducted a retrospective study on 87 patients who have had a transplant for more than 5 years, a period considered immunologically stable. We evaluated laboratory parameters such as glycemia, creatinine, total protein, and C-reactive protein (CRP), as well as demographic data, primary kidney disease, donor type, comorbidities, and infection incidence.
RESULTS: This study revealed clinical stability at over 5 years post-transplantation, with no significant differences between the 5-15 and over-15-years groups with regard to major comorbidities, except for HCV infection (p = 0.018). Reduced magnesium levels were associated with impaired renal function (p = 0.017) and inflammatory syndrome (p = 0.012). Viral infections were correlated with living donor grafts (p = 0.05), hypoproteinemia, and decreased eGFR (estimated glomerular filtration rate), while bacterial infections, namely urinary tract infections (UTIs), were linked to reduced eGFR (p = 0.05, p = 0.046). Female patients with hypomagnesemia had a higher incidence of recurrent UTIs (p = 0.03).
CONCLUSIONS: Hypomagnesemia correlates with increased infection risk in patients who received a renal transplant more than 5 years ago but does not significantly impact glycemic control or cardiovascular health.
