Distal renal tubular acidosis is a disease that occurs when the kidneys don't remove acid properly into the urine, leaving the blood too acidic (called acidosis).
Renal tubular acidosis - distal; Renal tubular acidosis type I; Type I RTA; RTA - distal; Classical RTA
Causes, incidence, and risk factors
Your kidneys normally regulate your body's pH by removing acids from the blood and discarding them into the urine.
Distal renal tubular acidosis (Type I RTA) is caused by a defect in the kidney tubes that causes acid to build up in the bloodstream.
Type I RTA is caused by a variety of conditions, including:
- Fabry disease
- Sickle cell disease
- Sjogren syndrome
- Systemic lupus erythematosus
- Wilson disease
- Use of certain drugs such as amphotericin B, lithium, and analgesics
