Acute renal failure (ARF), also known as acute kidney failure or acute kidney injury, is a rapid loss of renal function due to damage to the kidneys, resulting in retention of nitrogenous (urea and creatinine) and non-nitrogenous waste products that are normally excreted by the kidney. Depending on the severity and duration of the renal dysfunction, this accumulation is accompanied by metabolic disturbances, such as metabolic acidosis (acidification of the blood) and hyperkalaemia (elevated potassium levels), changes in body fluid balance, and effects on many other organ systems. It can be characterised by oliguria or anuria (decrease or cessation of urine production), although nonoliguric ARF may occur. It is a serious disease and treated as a medical emergency.
Acute (sudden) kidney failure is the sudden loss of the ability of the kidneys to remove waste and concentrate urine without losing electrolytes.
Cause of Acute Renal Failure
Pre-renal (causes in the blood supply):
• Hypovolemia (decreased blood volume), usually from shock or dehydration and fluid loss or excessive diuretics use.
• Hepatorenal syndrome in which renal perfusion is compromised in liver failure.
• Vascular problems, such as atheroembolic disease and renal vein thrombosis (which can occur as a complication of the nephrotic syndrome).
• Infection usually sepsis, systemic inflammation due to infection.
• Severe burns.
• Sequestration due to pericarditis and pancreatitis.
• Hypotension due to antihypertensives and vasodilators.
• Trauma & severe haemorrhage.
• Severe vomiting & diarrhea causing dehydration.
Intrinsic (damage to the kidney itself):
• Toxins or medication (e.g. some NSAIDs, aminoglycoside antibiotics, iodinated contrast, lithium, phosphate nephropathy due to bowel preparation for colonoscopy with sodium phosphates).
• Rhabdomyolysis (breakdown of muscle tissue) – the resultant release of myoglobin in the blood affects the kidney; it can be caused by injury (especially crush injury and extensive blunt trauma), statins, stimulants and some other drugs.
• Hemolysis (breakdown of red blood cells) – the hemoglobin damages the tubules; it may be caused by various conditions such as sickle-cell disease, and lupus erythematosus.
• Multiple myeloma, either due to hypercalcemia or “cast nephropathy” (multiple myeloma can also cause chronic renal failure by a different mechanism).
• Acute glomerulonephritis which may be due to a variety of causes, such as anti glomerular basement membrane disease/Goodpasture’s syndrome, Wegener’s granulomatosis or acute lupus nephritis with systemic lupus erythematosus.
• Acute pyelonephritis.
• Acute tubular necrosis.
• Blood incompatibility
Post-renal (obstructive causes in the urinary tract) due to:
• Medication interfering with normal bladder emptying (e.g. anticholinergics).
• Benign prostatic hypertrophy or prostate cancer.
• Kidney stones.
• Due to abdominal malignancy (e.g. ovarian cancer, colorectal cancer).
• Obstructed urinary catheter.
• Drugs that can cause crystalluria and drugs that can lead to myoglobinuria & cystitis.
OTHER CAUSES of Acute Renal Failure
• Malignant hypertension.
• Disorders associated with child birth; PPH, placenta previa.
Symptoms of Acute Renal or Kidney Failure
• Bloody stools.
• Breath odor.
• Brusing easily.
• Changes in mental statusor mood.
• Decreased appetite.
• Decreased sensation, especially in the hands or feet.
• Flank pain (between the ribs and hips).
• Hand tremor.
• High blood pressure.
• Metallic taste in mouth.
• Nausea or vomiting, may last for days.
• Persistent hiccups.
• Prolonged bleeding.
• Slow, sluggish movements.
• Swelling – generalized (fluid retention).
• Swelling of the ankle, feet, and leg swelling.
• Urination changes:
o Decrease in amount of urine.
o Excessive urination at night.
o Urination stops completely.
COMPLICATIONS of acute renal failure
• Cardiac arrhythmia.
• Congestive cardiac failure.
• Pulmonary oedema.
• Uraemic coma.
• Secondary infection.
GENERAL MANAGEMENT of Acute Renal Failure
• Correct cause.
• Maintain fluid, electrolyte balance.
• Bed rest.
• Restrict fluid to an amount equal to the volume of urine produced.
• Salt intake is also restricted.
• Protein, sodium & potassium intake is restriction.
• Diet should be high in carbohydrate content.
• Correct anaemia.
• Maintain daily record of
o Body weight.
o Fluid intake.
o Urine output.
o Blood urea.
o Serum electrolytes
• Dialysis is not necessary in all the cases of acute kidney failure. It is indicated & life saving particularly when; serum potassium is very high, deranged mental status, precarditis, anuria, fluid overload, serum creatinine > 10mg/dl.
Homeopathic Treatment for Acute Renal Failure
Homeopathy treats the person as a whole. It means that homeopathic treatment focuses on the patient as a person, as well as his pathological condition. The homeopathic medicines are selected after a full individualizing examination and case-analysis, which includes the medical history of the patient, physical and mental constitution etc. A miasmatic tendency (predisposition/susceptibility) is also often taken into account for the treatment of chronic conditions. The medicines given below indicate the therapeutic affinity but this is not a complete and definite guide to the treatment of this condition. The symptoms listed against each medicine may not be directly related to this disease because in homeopathy general symptoms and constitutional indications are also taken into account for selecting a remedy. To study any of the following remedies in more detail, please visit our Materia Medica section. None of these medicines should be taken without professional advice.
Homeopathy Remedies for Acute Renal Failure
Incipient stage of post scarlatinal nephritis, pain in loins, scanty urine without blood.
Apis is not so much a remedy for chronic Bright’s disease as for the acuter forms. There are oedematous swellings of the face and extremities, paleness, ascites, oedema pulmonum, pains in the head, back and limbs. Albuminuria following scarlatina. It may be of use in any form of Bright’s disease when there are dull pains in the kidneys, scanty urine and frequent Micturition. The urine is heavily charged with albumen and contains blood corpuscles. The oedema appears quickly, there is general dropsy and suppression of urine and perhaps an eruption of the skin like a nettle rash. The patient is drowsy, apathetic and has a bruised feeling all over. Apis in such cases acts best in trituration; do not depend on the tincture or dilutions. Hepar is recommended by Kafka in Bright’s disease following scarlatina. A valuable symptom for Apis is the feeling of suffocation. He does not see how he is get another breath.
Palliative in dropsical conditions where the urine is scanty. Also useful for coma & convulsions in the nephritis of pregnency.
This remedy corresponds to all stages of Bright’s disease, bearing a closer resemblance than any other remedy. It comes in later in the disease where there is dropsy, pale skin, waxen appearance, watery diarrhea and great thirst. The urine is dark, casts are abundant, and it contains much albumen. There are attacks of dyspnoea when lying down in the evening and after midnight, relieved by an expectoration of mucus. It may come in immediately after Aconite in many cases. “Blood boils” make a special indication for this remedy. Baehr, Millard and Hale question the usefulness of Arsenicum in kidney affections. However, it seems a simile to the large white kidney; in fact, one could hardly wish for a closer correspondence. Hughes considers it a favorite with anxiety and sinking of vital forces will call for Arsenicum. Calcarea arsenica has been used in the anaemia, progressive emaciation and debility of this disease with success.
Morbus Brightii from gout, suppurations or syphilis. Interstitial nephritis in its incipiency with digestive and nervous phenomena, hypochondriasis, irritability and vertigo.
Simple albuminuria, here it seems to occupy a place midway between Aconite and Arsenicum. Belladonna is of the greatest service in inflammation of the kidneys with piercing burning pains in the lumbar region, returning periodically with increased severity.
This remedy pictures nephritis with cutting pains in the lumbar region; the urine is passed in drops and is mixed with blood, with much urging. Post scarlatinal and post diphtheric kidney diseases with dropsy may indicate Cantharis.
Nephritis from heart disorders. It affords relief when there is extreme rapid & irregular action of the heart, and in general anasarca & ascites from mitral insufficiency.
Cuprum arsenicum is also useful in uraemic conditions and is praised highly by Goodno. Cuprum is a valuable remedy for uraemic eclampsia.
This remedy has an irritant action on the kidneys. It is homoeopathic to granular degeneration. Heart symptoms, feeble pulse, scanty, dark, turbid urine, faintness at the stomach, rheumatic pains will indicate it. It is especially useful when the circulation is weak. Rheumatic pains, pulmonary catarrh with profuse expectoration are marked symptoms.
Glonoine has albuminous urine and will sometimes be found useful in acute and haemorrhagic nephritis.
This remedy is said to be the most homoeopathic of all remedies in Bright’s disease. It has scanty, dark, albuminous urine containing casts. It excites a violent nephritis.
This remedy corresponds to the large white kidney. There is an albuminous, scanty and red urine; pale waxen color of the body; there are lumbar pains, great dyspnoea and excessive strangury. It takes the first rank among all the mercurials for nephritis, and it comes in the later stages. Syphilitic complication further indicate it. There is an expression of uneasiness on the face. Dr. Ludlam considers it our best remedy for the albuminous nephritis of pregnancy and Baehr lauds it in suppurative nephritis.
