Quality of life in older patients with CKD (BiCARB study)

Does oral sodium bicarbonate therapy improve function and quality of life in older patients with chronic kidney disease and low-grade acidosis? A randomised controlled trial

A randomised controlled trial is being undertaken to test whether bicarbonate treatment makes older people with advanced kidney disease healthier. 380 patients will receive either bicarbonate or dummy (placebo) tablets three times a day for two years. We test muscle strength and bulk, walking and balance ability, quality of life, kidney, bone and blood vessel function at intervals over the two-year period. We record blood pressure and side effects, record falls, admissions to hospital and contact with GPs, and also test the cost of treatment against the cost of not treating.

More information on the trial is available at the BiCARB Study site.
