  Lactic acidosis - Wikipedia, the free encyclopedia
Lactic acidosis is a condition caused by the buildup of lactic acid in the body.
It leads to acidification of the blood (acidosis), and is considered a distinct form of metabolic acidosis.
Lactic acidosis may be caused by diabetic ketoacidosis or liver or kidney disease, as well as some forms of medication (most notably metformin).

 metabolic acidosis   (Site not responding. Last check: 2007-10-20)
Metabolic acidosis is a condition in which the acid level within the blood is higher than normal.
By definition, the condition is not due to breathing problems, which is known as respiratory acidosis.
Metabolic acidosis may be suspected after a history and physical exam.

 Acidosis
Acidosis is a condition in which body chemistry becomes imbalanced and overly acidic.
Acidosis occurs when the body loses its alkaline reserve.
Some causes of acidosis include kidney, liver, and adrenal disorders; improper diet; malnutrition; obesity; ketosis; anger; stress; fear; anorexia; toxemia; fever; and the con-sumption of excessive amounts of niacin, vitamin C, or aspirin.

 8.3 Acidosis and Renal Failure
This is called Renal Tubular Acidosis (RTA) and this is a normal anion gap or hyperchloraemic type of acidosis.
The acidosis occurring in uraemic patients is due to failure of excretion of acid anions (particularly phosphate and sulphate) because of the decreased number of nephrons.
Most other forms of metabolic acidosis are of relatively short duration as the patient is either treated with resolution of the disorder or the patient dies.

 Respiratory acidosis
Respiratory acidosis is a condition in which a build-up of carbon dioxide in the blood produces a shift in the body's pH balance and causes the body's system to become more acidic.
Respiratory acidosis is an acid imbalance in the body caused by a problem related to breathing.
If the acidosis is related to an overdose of narcotics, or a drug overdose is suspected, the patient may be given a dose of naloxone, a drug that will block the respiratory-depressing effects of narcotics.

 Metformin and Fatal Lactic Acidosis   (Site not responding. Last check: 2007-10-20)
Ninety percent of metformin is excreted unchanged by the kidneys and lactic acidosis typically occurs in patients with renal insufficiency.
Significant renal impairment (serum creatinine >0.16 mmol/L) is a contraindication to the use of metformin, and mild renal disease increases the risk of lactic acidosis.
In situations predisposing to dehydration such as fasting for surgery or contrast radiography, metformin should be ceased at least 48 hours prior to the procedure (or on admission for an emergency procedure), and not restarted until the patient has fully recovered and is eating and drinking normally.

 MedlinePlus Medical Encyclopedia: Respiratory acidosis
Respiratory acidosis occurs when the lungs cannot remove all of the carbon dioxide (a normal by-product of metabolism) produced by the body.
Other conditions that may lead to respiratory acidosis include: obesity hypoventilation syndrome, excessive fatigue of the diaphragm or muscles of the rib cage, or severe deformities of the spine and rib cage (for example, severe scoliosis).
Respiratory acidosis may be a sign of respiratory failure, with dangerously low blood oxygen levels.

 THE MERCK MANUAL--SECOND HOME EDITION, Acidosis in Ch. 159, Acid-Base Balance
Acidosis is excessive blood acidity caused by an overabundance of acid in the blood or a loss of bicarbonate from the blood (metabolic acidosis), or by a buildup of carbon dioxide in the blood that results from poor lung function or slow breathing (respiratory alkalosis).
The diagnosis of acidosis generally requires the measurement of blood pH in a sample of arterial blood, usually taken from the radial artery in the wrist.
When acidosis is severe, bicarbonate may be given intravenously; however, bicarbonate provides only temporary relief and may cause harm—for instance, by overloading the body with sodium and water.

Lactic acidosis emerged around the same time as body fat and metabolic changes seen in people on ARV regimens (aka lipodystrophy), and some researchers suggest these conditions may be linked.
Lactic acidosis is a side-effect of the long term use of the reverse transcriptase inhibitor (RTI) class of HIV drugs (AZT, 3TC, d4T, ddI, and abacavir) because reverse transcriptase and polymerase gamma are similar, and what inhibits one can inhibit the other.

 The WorldWide Intensivist - Hyperchloraemic acidosis
Such acidosis may on occasion be due to an overwhelming stress on the kidney (for example, ongoing massive intestinal bicarbonate loss) but is far more likely to be related to impairment of the renal mechanisms themselves.
Acidosis of this type is often both initiated and perpetuated by renal tubular dysfunction, hence the term "renal tubular acidosis" (RTA).
RTA excludes people with severe renal dysfunction, where acidosis is often associated with a moderately raised anion gap, and is due to overall renal dysfunction with inability to clear hydrogen ions.
