Renal Tubular Acidosis - General Practice Notebook
The whole terminology of renal tubular acidosis can be confusing to the newcomer. Important features to grasp are: The acidosis refers to the plasma, not the contents of the renal tubules. Indeed, in classical (type I) renal tubular acidosis the urine is often alkaline. Thus renal tubular acidosis is a metabolic acidosis of renal tubular origin. There are three main types, named I, II and IV. Type III has become obsolete. The three types have different sites of localisation in the renal tubule. However, again the terminology is confusing in that type II is proximal, type I distal.

Renal Tubular Acidosis (rta)
By L. Aimee Hechanova, MD, Assistant Professor of Medicine, Texas Tech University; Attending Nephrologist, University Medical Center (See also Introduction to Disorders of Kidney Tubules .) In renal tubular acidosis, the kidney tubules malfunction, resulting in excess levels of acid in the blood. The tubules of the kidneys that remove acid from the blood are damaged when a person takes certain drugs or has another disorder that affects the kidneys. Often muscle weakness and diminished reflexes occur when the disorder has been present for a long time. Blood tests show high acid levels and a disturbance of the body's acid-base balance. Some people drink a solution of baking soda every day to neutralize the acid. To function normally, body acids and alkali (such as bicarbonate) must be balanced. Normally, the breakdown of food produces acids that circulate in the blood. The kidneys remove acids from the blood and excrete them in the urine. This function is predominantly carried out by the kidney tubules . In renal tubular acidosis, the kidney tubules malfunction in one of two ways that tend to increase acids in the blood ( metabolic acidosis ): Too little of the acids the body produc
This is a review of the pathophysiology, diagnosis and treatment of Renal Tubular Acidosis intended for 3rd and 4th year medical students and others learning clinical medicine.
Renal Tubular Acidosis
Renal tubular acidosis (RTA) is a disease that occurs when the kidneys fail to excrete acids into the urine, which causes a person's blood to remain too acidic. Without proper treatment, chronic acidity of the blood leads to growth retardation, kidney stones, bone disease, chronic kidney disease, and possibly total kidney failure. The body's cells use chemical reactions to carry out tasks such as turning food into energy and repairing tissue. These chemical reactions generate acids. Some acid in the blood is normal, but too much acidacidosiscan disturb many bodily functions. Healthy kidneys help maintain acid-base balance by excreting acids into the urine and returning bicarbonatean alkaline, or base, substanceto the blood. This "reclaimed" bicarbonate neutralizes much of the acid that is created when food is broken down in the body. The movement of substances like bicarbonate between the blood and structures in the kidneys is called transport. One researcher has theorized that Charles Dickens may have been describing a child with RTA in the character of Tiny Tim from A Christmas Carol. Tiny Tim's small stature, malformed limbs, and periods of weakness are all possible consequence
Patients with renal tubular acidosis (RTA) are often asymptomatic but may present with complaints of muscular weakness related to associated hypokalemia. Patients with severe acidemia can show hyperventilation or Kussmaul breathing due to respiratory compensation. Patients with RTA have a low arterial pH and serum bicarbonate with hyperchloremia and a normal serum anion gap. The urine pH exceeds 5.5 in classic distal RTA, but is lower than 5.0 i ...

Each time our internal organs do something, such as digesting food or healing damaged tissue, chemical reactions take place in the body's cells. These reactions cause acid to go into the bloodstream. Normally, the kidneys remove excess acid from blood, but certain diseases, genetic defects, or drugs can damage a kidney's ability to do this important job. This can allow too much acid to build up in the blood and cause problems. When this happens, ...
Distal renal tubular acidosis is a disease of defective urinary acidification, which is caused by insufficient net acid excretion by the kidney. Fiona E. Karet, in Genetic Diseases of the Kidney , 2009 Distal renal tubular acidosis is a disease of defective urinary acidification, which is caused by insufficient net acid excretion by the kidney. Unfortunately, the classification of the RTAs can be confusing, because within the overall historical ...
