Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with chronic kidney disease on hemodialysis for at least three months and elevated plasma homocysteine levels.

Probably not a fit

Patients with acute illnesses, malabsorption issues, or those receiving certain medications or supplements may not benefit from this study.

What this trial studies

This clinical trial evaluates the effectiveness of zinc supplementation compared to folic acid in reducing hyperhomocysteinemia in patients with chronic kidney disease undergoing hemodialysis. Hyperhomocysteinemia is a significant risk factor for cardiovascular events in these patients. The study will randomly assign ninety participants to receive either zinc sulfate or folic acid over a period of one and a half years at Chittagong Medical College Hospital in Bangladesh. The aim is to determine if zinc can provide a more effective solution for managing elevated homocysteine levels in this population.

Why it matters

Potential benefit: If successful, this study could offer a new treatment option to reduce cardiovascular risks in hemodialysis patients.

How similar studies have gone: While folic acid has been widely studied and shown efficacy, the use of zinc supplementation in this context is less established, making this approach relatively novel.
