Input: The literature search yielded 359 reports of which only one study was identified that met our inclusion criteria and reported relevant clinical endpoints. This study randomised 4110 adult participants with a functioning kidney transplant and elevated homocysteine levels to folic acid plus high dose B multivitamins or low dose multivitamins who were followed for a mean 4.0 years. Despite effectively lowering homocysteine levels) in homocysteine levels at follow-up (MD -4.40 μmol/L, 95% CI -5.98 to -2.82) there was no evidence the intervention impacted on any of the outcomes reported including cardiovascular mortality (RR 0.91, 95% CI 0.69 to 1.20), all-cause mortality (RR 1.04, 95% CI 0.88 to 1.22), myocardial infarction (RR 1.02, 95% CI 0.77 to 1.35), stroke (RR 1.08, 95% CI 0.69 to 1.71), commencement of renal replacement therapy (RR 1.12, 95% CI 0.91 to 1.37) or all reported adverse events (RR 1.02, 95% CI 0.87 to 1.20). There was no evidence the intervention impacted on the primary endpoint of the study, a cardiovascular event composite (RR 0.99, 95% CI 0.85 to 1.15). The study was of high quality. There is no current evidence to support the use of homocysteine lowering therapy for cardiovascular disease prevention in kidney transplant recipients.
Output:

The aim of this review was to determine if homocysteine lowering therapies effectively reduce cardiovascular event rates in kidney transplant recipients. A single study was identified that randomised 4110 adult participants with a functioning kidney transplant to homocysteine lowering with folic acid and high dose multivitamins or to low dose multivitamins and followed them for an average of four years. Despite effectively lowering homocysteine levels, there was no evidence of benefit for any of a range of cardiovascular events. Similarly there was no evidence of harm.
