Prognosis and recovery of Metabolic Acidosis is dependent on the causative factor. Appropriate and timely treatment takes time but help in recovery. Some people totally recover from Metabolic Acidosis whereas others may develop


COMPLICATIONS FROM USE OF BICARBONATES:

Caution with bicarbonate therapy is indicated because of its potential complications, including the following:


PROGNOSIS:

The prognosis is directly related to the underlying etiology and the ability to treat or correct that particular disorder.

  • A study in 2016 indicated that in patients undergoing renal replacement therapy, an association exists between uncorrected severe metabolic acidosis (serum bicarbonate concentrations of below 20 mmol/L) and a 10-year risk for coronary heart disease of over 20%, as well as a high overall mortality rate.[1]
  • A study in 2017 indicated that a high rate of metabolic acidosis occurs in kidney transplant recipients; a low serum total CO2 concentration (< 22 mmol/L) was found in about 30-70% of such patients with an estimated glomerular filtration rate of under 30 mL/min per 1.73 m2. The study also found evidence that metabolic acidosis may increase the likelihood of mortality in kidney transplant recipients[2] and graft failure.
  • In a study of emergency department patients with acute kidney injury, metabolic acidosis is independently associated with mortality, along with sex, age over 60 years, blood urea nitrogen (BUN) concentration, hyperkalemia, cause of renal failure, and type of renal failure. [3]
