Populations and Risk Factors
- Diabetes mellitus (leading cause — approximately 40% of CKD cases)
- Hypertension (second leading cause — approximately 30% of CKD cases)
- Adults over 60 (age-related nephron loss)
- African American, Hispanic, and Indigenous populations (higher incidence and faster progression)
- Family history of kidney disease
- Obesity and metabolic syndrome
- Recurrent kidney infections or kidney stones
- Autoimmune diseases (lupus nephritis, IgA nephropathy)
- Long-term NSAID or nephrotoxic drug use
- Polycystic kidney disease (genetic)
- Smoking (accelerates progression)
Causes and Pathophysiology
- Progressive nephron destruction: Regardless of the original cause, CKD follows a common pathway. Damaged nephrons are lost. Remaining nephrons compensate by hyperfiltrating (increasing individual GFR). This compensatory hyperfiltration eventually causes glomerular hypertension and further nephron injury, creating a self-perpetuating cycle of destruction.
- Staging by GFR:
- Stage 1: GFR > 90 (kidney damage with normal function — asymptomatic)
- Stage 2: GFR 60-89 (mild decrease — usually asymptomatic)
- Stage 3: GFR 30-59 (moderate decrease — anemia, early bone disease begin)
- Stage 4: GFR 15-29 (severe decrease — significant symptoms; prepare for renal replacement)
- Stage 5 (ESRD): GFR < 15 (kidney failure — dialysis or transplant required for survival)
- Uremia: Accumulation of urea, creatinine, and other nitrogenous waste products causes systemic toxicity affecting the brain (encephalopathy), heart (uremic pericarditis), skin (pruritus), bones (renal osteodystrophy), and immune system (immunosuppression).
- Systemic complications:
- Anemia (reduced erythropoietin production by damaged kidneys)
- Renal osteodystrophy (impaired vitamin D activation leads to poor calcium absorption, secondary hyperparathyroidism, and bone resorption)
- Metabolic acidosis and hyperkalemia (impaired acid and potassium excretion — cardiac arrest risk)
- Fluid overload and hypertension (impaired sodium and water excretion)
- Uremic pericarditis (late-stage, potentially fatal)
- Peripheral neuropathy (uremic toxins damage peripheral nerves)
- Uremic pruritus (toxin deposition in skin)
- Platelet dysfunction (easy bruising despite normal platelet count)
Signs and Symptoms
- Early stages: often asymptomatic (diagnosed incidentally on bloodwork)
- Fatigue and weakness (anemia)
- Edema (fluid retention), especially periorbital (morning) and pedal (evening)
- Hypertension (fluid overload and RAAS activation)
- Nausea, anorexia, metallic taste (uremia)
- Pruritus (uremic toxin deposition in skin — often severe and debilitating)
- Muscle cramps and restless legs (electrolyte imbalances)
- Peripheral neuropathy (numbness, tingling, burning in extremities)
- Easy bruising (platelet dysfunction)
- Bone pain (renal osteodystrophy)
- Cognitive impairment and sleep disturbances (advanced stages)
- Uremic frost (rare — urea crystals on skin in end-stage disease)
Red Flags
- Uremic crisis: Confusion, pericarditis (chest pain worse with breathing), seizures — emergency referral
- Hyperkalemia symptoms: Muscle weakness, palpitations, cardiac arrhythmia — potentially fatal; emergency
- Pulmonary edema: Severe dyspnea, orthopnea, pink frothy sputum — call 911
- Sudden absence of urine output (anuria): May indicate acute-on-chronic renal failure — urgent referral
MT Considerations
- Gentle relaxation massage is indicated at all CKD stages with physician awareness. Massage can meaningfully improve quality of life by reducing anxiety, improving sleep, addressing uremic pruritus (gentle skin stimulation), and managing peripheral neuropathy discomfort.
- AV fistula/graft site: Never apply pressure, blood pressure cuffs, or tourniquet-like positioning to the extremity with a dialysis fistula or graft. Avoid the entire ipsilateral arm.
- Deep tissue massage is contraindicated: Platelet dysfunction causes easy bruising. Renal osteodystrophy makes bones fragile. Use light to moderate pressure only.
- Skin assessment: Uremic pruritus causes excoriations — assess skin integrity before each session. Uremic skin is dry, fragile, and easily damaged.
- Edema management: Elevate edematous limbs. Monitor for edema changes between sessions.
- Dialysis scheduling: Schedule massage on non-dialysis days. Clients are hemodynamically unstable on dialysis days (fluid shifts, hypotension). If same-day treatment is unavoidable, wait at least 1 hour post-dialysis.
- Session duration: Shorter sessions may be necessary due to fatigue
- Position changes: Antihypertensive medications cause orthostatic hypotension — slow repositioning is essential
- Medications: Erythropoiesis-stimulating agents (epoetin alfa) treat anemia. Phosphate binders manage bone disease. Calcimimetics (cinacalcet) treat secondary hyperparathyroidism. Multiple antihypertensives are standard. Post-transplant clients are on immunosuppressants — infection precautions required.
CMTO Exam Relevance
- Category: A7 Systemic Conditions — Urinary
- CKD is a systemic condition requiring comprehensive treatment modifications across multiple body systems
- AV fistula/graft site protection is an absolute rule — no pressure, no cuffs, no tourniquet
- Platelet dysfunction (easy bruising despite normal platelet count) contraindicate deep tissue work
- Renal osteodystrophy (bone fragility) — adjust pressure over bony prominences
- 5-stage GFR classification and the significance of each stage
- Cardiovascular disease is the leading cause of death in CKD (not renal failure itself)
Key Takeaways
- CKD is a progressive, irreversible condition most commonly caused by diabetes and hypertension
- It produces systemic complications affecting virtually every body system
- Never apply pressure to an AV fistula/graft site. Schedule massage on non-dialysis days
- Use light pressure due to platelet dysfunction (bruising) and bone fragility (renal osteodystrophy)
- Massage can meaningfully improve quality of life in CKD by addressing anxiety, sleep, pruritus, and neuropathy
- Cardiovascular disease is the leading cause of death — manage accordingly
