![]() ![]() What causes Type 1 RTA?ĭistal renal tubular acidosis (type I RTA) is caused by a defect in the kidney tubes that causes acid to build up in the blood. This form of RTA has also been referred to as juvenile RTA. ![]() Type 3: combined proximal and distal This rare pattern was observed in the 1960s and 1970s as a transient phenomenon in infants and children with dRTA (possibly in relation with some exogenous factor such as high salt intake) and is no longer observed. Type II most often occurs during infancy and may go away by itself. Type I is also called distal renal tubular acidosis. Type II RTA is less common than type I RTA. Proximal renal tubular acidosis (type II RTA) occurs when bicarbonate is not properly reabsorbed by the kidney’s filtering system. Renal tubular acidosis (RTA) is a group of transport defects in the reabsorption of bicarbonate (HCO3), the excretion of hydrogen ion (H+), or both, resulting in systemic acidosis and hypokalemia with a normal glomerular filtration rate. Type 4 RTA Hyperkalemia is treated with volume expansion, dietary potassium restriction, and potassium-wasting diuretics (eg, furosemide 20 to 40 mg po once/day or bid titrated to effect). ![]() Type 4 RTA, or hyperkalemic RTA, occurs when the tubules are unable to remove enough potassium, which also interferes with the kidney’s ability to remove acid from the blood.
