Proximal renal tubular acidosis
Alternate Names : Renal tubular acidosis - proximal, Type II RTA, RTA - proximal, Renal tubular acidosis type II
Treatment
The goal is to restore the normal pH (acid-base level) and electrolyte balance to the body. This will indirectly correct bone disorders and reduce the risk of osteomalacia and osteopenia in adults. Some adults may need no treatment. All children need alkaline medication to prevent acid-induced bone disease such as rickets, and to allow normal growth. The underlying cause should be corrected if it can be found.
Alkaline medications include sodium bicarbonate and potassium citrate. They correct the acidic condition of the body and correct low blood potassium levels. Thiazide diuretics may indirectly decrease bicarbonate loss but may worsen the low blood potassium levels. Vitamin D and calcium supplements may be needed to help reduce skeletal deformities resulting from osteomalacia or rickets.
Prognosis (Expectations)
Although the underlying cause of proximal renal tubular acidosis may go away by itself, the effects and complications can be permanent or life-threatening. Treatment is usually successful.
