Rehabilitation Therapy for Acute Kidney Damage

Introduction:

Acute kidney damage occurs in 20 percent of all hospitalized patients. Furthermore, acute kidney injury is associated with chronic kidney disease, cardiovascular disease, and end-stage kidney disease. Only a few patients receive follow-up care and rehabilitation after suffering from acute kidney damage. It is important to provide rehabilitation therapy, lifestyle changes, medicines, control of blood pressure, and education for the patients after episodes of acute kidney injury as they belong to high-risk groups. If left untreated, this disease could lead to complications and death.

What Is Acute Kidney Damage?

Acute kidney damage is the sudden stopping of kidneys within a few hours or days, resulting in kidney failure or loss of kidney function. Renal impairment for more than seven days but less than 90 days is referred to as acute kidney damage. Generally, acute kidney damage occurs in elderly people and is associated with other grave illnesses that result in a decrease in urine production. However, it is also found among children and the youth. This disease would require early detection and prompt treatment, such as dialysis(management used to remove excess fluid and waste from the body in kidney failure cases) for a short period to return the kidney to normal.

What Causes Acute Kidney Damage?

The three leading acute kidney damage causes include the following.

Reduced Blood Flow to the Kidneys:

• Blood loss.

• Severe dehydration, excessive vomiting, and diarrhea.

• Serious burns.

• Heart and liver failure.

• Blood pressure medications.

• Drugs such as Aspirin, Ibuprofen, Naproxen.

Block in the Drainage of Kidneys:

• Enlarged prostate.

• Kidney stones.

• Blood clots in the urinary tract.

• Ovarian, bladder, cervical, or prostate tumors.

Direct Damage to the Kidneys:

• Cholesterol deposits.

• Drugs damaging the kidneys include NSAIDs (nonsteroidal anti-inflammatory drugs), antibiotics, and chemotherapy.

• Glomerulonephritis (inflammation of the kidney filters).

• Auto-immune diseases such as lupus, vasculitis (inflamed and damaged blood vessels), scleroderma (thickening and inflammation of the skin and other areas of the body), and multiple myeloma (blood cancer that affects plasma cells in bone marrow).

What Are the Symptoms of Acute Kidney Damage?

The acute kidney damage signs include the following.

• Decreased urine output.

• Swelling of legs, ankles, and feet.

• Tired and drowsiness.

• Loss of appetite.

• Shortness of breath.

• Confusion.

• Chest pain or pressure.

• Fever and muscle twitching.

• Joint pain.

• Coma or seizures in severe cases.

What Are the Complications of Acute Kidney Damage?

The complications of acute damage to the kidney or acute failure of the kidney are the following.

1. Fluid Accumulation: Acute damage to the kidney causes fluid accumulation within the body. The person has shortness of breath due to this.

2. Chest Pain: Inflammation of the heart's lining

3. Muscle Weakness: Due to the fluid and electrolyte imbalance within the body, paralysis and heart problems.

4. Acidic Blood: The body's blood contains more acids because the kidneys fail (metabolic acidosis).

5. Permanent Kidney Damage: Unbranded acute kidney damage left untreated may cause permanent or chronic kidney damage, known as end-stage renal disease. Such a disease would need permanent dialysis or transplant because the kidney stops working entirely.

6. Death is a severe complication of untreated acute kidney damage.

How to Treat Acute Kidney Damage?

Treatment of acute kidney damage should be facilitated in the hospital. The interventions the patient receives in the hospital are listed below.

• Resolution of the etiology causing acute kidney damage.

• Fluid and electrolyte correction through intravenous infusion

• Diuretics medication to remove excess fluid from the body.

• Calcium, glucose, or sodium polystyrene sulfonate administration to prevent the buildup of potassium in the body.

• This action includes removing the toxins, excess fluids, and potassium from the body, which will be accomplished when the kidneys heal themselves and work regularly again.

What Is the Rehabilitation Therapy for Acute Kidney Damage?

Research suggests including management strategies and post-follow-up care to enhance recovery after acute kidney damage. However, the intensity of the follow-up care depends on the following risk factors.

• Patient-specific risk factors include pre-existing hypertension, cardiovascular diseases, diabetes, older age, and recurrent episodes of acute kidney injury.

• Characteristics of acute kidney damage and episodes.

• Degree of kidney recovery.

The rehabilitation program should include strategies and therapies to prevent complications and promote faster renal recovery.

Renal Rehabilitation:

• Renal rehabilitation enhances the patient's functional level in the social, psychological, and physiological dimensions, reducing mortality and morbidity. The period of renal rehabilitation is anywhere between six and twelve weeks.

• Training in exercise or physiotherapy, pharmaceutical control, food and hydration management, application of educational tactics, and psychological and vocational counseling are the other important components of renal rehabilitation.

Management Interventions:

• The patient must be treated for his underlying disease to promote renal repair. Immunosuppressives, cytotoxic drugs, and steroids are used in renal rehabilitation.

• After acute kidney damage, simple dietary and life advice is given to promote renal and cardiovascular health.

• In follow-up, treatment with pharmaceuticals would be very important for patients.

• Patients who require dialysis need individualized programs according to their condition.

Education Interventions:

• The patients suffering from the disease, their caregivers, and their families are educated on the etiology, diagnosis, risk factors, and follow-up to avoid further damage to the kidney.

• Fluid maintenance, self-management, and health education to heal in the patient's care should be performed early.

Lifestyle and Home-Based Treatments for Rehabilitation:

• Dieticians are recommended an exclusive diet that is good for the kidneys in recovery.

• Avoid foods with high potassium content; these include grapes, strawberries, peppers, apples, and cauliflowers.

• Avoid foods high in potassium, including potatoes, oranges, bananas, tomatoes, and spinach.

• To avoid sodium, avoid products that are overly salinated.

• Dieticians advise against using high phosphorus until the kidneys function properly because it weakens the bones.

Physiotherapy Management:

The physiotherapist's contribution to renal rehabilitation is to create a well-thought-out, extensive exercise regimen. Participants are required to complete the exercises at home on at least two other days per week, and the lessons last one to two hours over six to twelve weeks.

• The objectives are to enhance muscular strength, flexibility, and fitness in general.

• Improve the quality of life.

• Reduce high blood pressure.

• Improve glycemic control.

• Strengthen the heart and lungs.

• Lose weight and build confidence.

• Combat or reverse the adverse consequences of steroidal treatment, including weight gain after transplantation, weakened bones, and muscle wasting.

What Is the Importance of Exercise in Acute Kidney Damage?

Managing patients with acute kidney injury involves exercise and physiotherapy for renal rehabilitation.

• Antioxidative Effects: It enhances the level of glutathione and catalase, which decrease lipid peroxidation.

• Anti-inflammatory Activities: Anti-inflammatory activities are displayed by modulating T-cell activation and macrophage infiltration and inducing anti-inflammatory myokines.

• Autophagy Upregulation: Autophagy activation promotes healing after kidney injury by minimizing the tubular injury and improving renal function. Mesenchymal stem cells or their conditioned medium have been shown to improve autophagy, contributing to renoprotection by enhancing kidney function and reducing oxidative stress. Before the induction of apoptosis, autophagy is activated in AKI(acute kidney injury), which prevents tissue damage and cell death. Inhibition or stimulation of autophagy may serve as a promising therapeutic strategy to hinder AKI's progression and slow subsequent chronic renal disease progression.

• Anti-Fibrotic Effects: Anti-fibrotic effects of exercise and drugs during the recovery from acute kidney injury. This exercise after AKI may decrease kidney damage and improve long-term outcomes by reducing inflammation and fibrosis. It mediates therapeutic effects by suppressing the recruitment of fibrocytes and the expression of fibrotic genes, thereby relieving renal fibrosis induced by tanshinone IIA therapy. Gal-8(galectin-8) exerts anti-fibrotic effects by suppressing apoptosis and upregulating the redifferentiation of epithelial cells while reducing the activation of fibroblasts. Suppression of renal fibrogenesis through FGF2 (fibroblast growth factor2) treatment prevents AKI from evolving into chronic kidney disease. ω3PUFAs (omega-3 polyunsaturated fatty acids) inhibit the progression from AKI to CKD (chronic kidney disease) by preventing renal fibrosis, and certain antifibrotic effects have also been attributed to EPA(eicosapentaenoic acid) metabolites.

• Improve muscle strength, mobility, fitness, heart and lung function, and self-esteem.

• It helps to bring the blood pressure down and keeps the weight under control.

Dialysis in the Treatment of Acute Kidney Damage:

• Patients with acute kidney damage who will need dialysis are admitted to or are patients in a dialysis center on the service of a nephrologist (kidney specialist).

• The device filters the blood using a dialysis machine, removing toxins and wastes. Blood is pumped through the machine, cleaned, and infused into the body.

• Blood pressure is checked periodically. The laboratory results from the week help the rehabilitation team act and enhance the patient's recovery.

Conclusion

Acute kidney injury is a complex condition that requires more renal recovery treatments. An exercise rehabilitation program improves renal recovery after acute renal damage and reduces the risk of progression to chronic kidney disease. Researchers support healthcare providers' provision of follow-up and rehabilitation for survivors of acute kidney damage or injury.
