Renal Tubular Acidosis

Significant bilateral nephrocalcinosis (calcification of the kidneys) on a frontal X-ray (radiopacities (white) in the right upper and left upper quadrant of the image), as seen in distal renal tubular acidosis. Renal tubular acidosis (RTA) is a medical condition that involves an accumulation of acid in the body due to a failure of the kidneys to appropriately acidify the urine . [1] In renal physiology , when blood is filtered by the kidney, the filtrate passes through the tubules of the nephron , allowing for exchange of salts , acid equivalents, and other solutes before it drains into the bladder as urine . The metabolic acidosis that results from RTA may be caused either by failure to reabsorb sufficient bicarbonate ions (which are alkaline ) from the filtrate in the early portion of the nephron (the proximal tubule ) or by insufficient secretion of hydrogen ions (which are acidic) into the latter portions of the nephron (the distal tubule ). Although a metabolic acidosis also occurs in those with renal insufficiency , the term RTA is reserved for individuals with poor urinary acidification in otherwise well-functioning kidneys. Several different types of RTA exist, which all Continue reading >>

    K+ ions can be interchanged for H+ ions over the cell membranes.
    In the fluid the cells are bathed in outside the cell the main positive ion is sodium Na+, in the cell (intracellular fluid) the main positive ion is potassium K+.
    This is the classical way of seeing the relationship between pH and [K+]:
    If K+ ions were high in the fluid outside the cell, it would be exchanged for H+ ion within the cells, so lowering the K+ ion concentration outside the cell, but raising the H+ ion concentration thus lowering the pH outside the cell.
    A low K+ concentration outside the cell will lead to the raising of the pH of the fluid outside the cell because of H+ ions from outside the cell being exchanged for K+ ions from inside the cell.

    Hypokalemia causes Alkalosis.
    The reason:
    Its three fold

    In body, H+ and K+ (Hydrogen and Potassium ions) are exchanged with one another, say for example, a cell wants one potassium inside it, what it does is it gives one hydrogen ion to the outside and in exchange takes the needed potassium inside.
    An hypokalemic state is very dangerous to the body (mainly affects the heart and skeletal muscles in this scenario) so what the body does is it takes hydrogen ion from the outside (extracellular fluid) giving the blood some potassium ion in exchange.
    So, there is decreased hydrogen ion concentration (increased pH) in blood, resulting in alkalosis

    Hypokalemia also increases hydrogen ion excretion (in proximal and distal tubules) so this is the second cause of alkalosis.



    Hypokalemia also increases ammonia production in proximal tubule, thus increasing hydrogen ion excretion again along with increased reabsorption of bicarbonate.

What is HYPOKALEMIA? What does HYPOKALEMIA mean? HYPOKALEMIA meaning - HYPOKALEMIA pronunciation - HYPOKALEMIA definition - HYPOKALEMIA explanation - How to pronounce HYPOKALEMIA? Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/... license. Hypokalemia, also spelled hypokalaemia, is a low level of potassium (K+) in the blood serum. Normal potassium levels are between 3.5 and 5.0 mmol/L (3.5 and 5.0 mEq/L) with levels below 3.5 mmol/L defined as hypokalemia. Mildly low levels do not typically cause symptoms. Symptoms may include feeling tired, leg cramps, weakness, and constipation. It increases the risk of an abnormal heart rhythm such as bradycardia and cardiac arrest. Causes of hypokalemia include diarrhea, medications like furosemide and steroids, dialysis, diabetes insipidus, hyperaldosteronism, hypomagnesemia, and not enough intake in the diet. It is classified as severe when levels are less than 2.5 mmol/L. Low levels can also be detected on an electrocardiogram (ECG). Hyperkalemia refers to a high level of potassium in the blood serum. The speed at which potassium should be replaced depends on whether or not there are symptoms or ECG changes. Mildly low levels can be managed with changes in the diet. Potassium supplements can be either taken by mouth or intravenously. If given by intravenous, generally less than 20 mmol are given over an hour. High concentration solutions (40 and more mmol/L) should be given in a central line if possible. Magnesium replacement may also be required. Hypokalemia is one of the most common waterelectrolyte imbalances. It affects about 20% of people admitted to hospital. The word "hypokalemia" is from hypo- means "under"; kalium meaning potassium, and -emia means "condition of the blood".

Ibuprofen-induced Hypokalemia And Distal Renal Tubular Acidosis: A Patients Perceptions Of Over-the-counter Medications And Their Adverse Effects

Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) which is available over-the-counter (OTC) as a nonprescription drug. It is used widely as an antipyretic and analgesic.

Hypokalaemia And Metabolic Acidosis

Home | Education | Hypokalaemia and Metabolic Acidosis 35 year old Aboriginal female presents with a 2/52 Hx of weakness, thirst and nausea. Presents to ED unable to lift her hands. Admitted 3/12 ago with something similar but doesnt know what it was and her medical notes are not immediately available. No other past medical history of note. Examination reveals a quiet, dehydrated lady with generalised non-lateralising weakness in all 4 limbs. Bedside venous blood gas results included: Sinus rhythm with sinus arrhythmia at a rate of 72 bpm. U waves noted most prominently in leads V1-V3 Sinus arrhythmia [sinus rhythm with slight variation (>0.16 seconds) in the sinus cycles] Normal anion gap metabolic acidosis. The 2 most common causes in ED Other causes are many and varied. There are several mnemonics out there the most recent edition of Rosen suggests: F-USED CARS Basically (and rather obviously), a metabolic acidosis is caused by either excess acid or a loss of alkali. Excess acid may be produced by the body itself or may be exogenous. Calculating the anion gap is used in the context of having made a diagnosis of a metabolic acidosis to help determine possible causes. Its an arti Continue reading >>

Its causes are diverse, and its consequences can be serious, inclu ...
