Rhabdomyolysis

🔬 Practice-Changing Findings
Evidence from RCTs and meta-analyses published in the last 12 months.

1. CDK4/6 inhibitor-statin interaction and rhabdomyolysis in breast cancer treatment: a case-based systematic review.

Cancer chemotherapy and pharmacology (2026) - Systematic Review

Key Findings

  • Increased CK ranged from 3,070 to 47,000 U/L, with onset from 3 days to 48 months after CDK4/6 inhibitor-statin exposure or shortly after statin dose escalation.
  • CK levels ranged from 3,070 to 47,000 U/L, AKI occurred in five cases, five patients recovered fully, one had persistent renal dysfunction, and mortality occurred in one case.

📋 Practice Implication: Medication reconciliation for patients on CDK4/6 inhibitors should specifically flag statins and recent statin dose escalation as triggers for urgent CK and renal assessment.

2. Factors associated with acute kidney injury in rhabdomyolysis: Insights from a prospective study.

World journal of nephrology (2026) - Prospective Study

Key Findings

  • AKI developed in 51.9% of 54 ICU patients with rhabdomyolysis.
  • A McMahon score threshold of 4.75 predicted AKI with 78.6% sensitivity and 76.9% specificity, while initial LDH and bicarbonate were independently associated with AKI occurrence.

📋 Practice Implication: Early triage should combine CK with admission LDH, bicarbonate, and McMahon score rather than waiting for creatinine trends alone.

3. Primary aldosteronism-induced hypokalemic rhabdomyolysis syndrome: a case report and literature review.

Frontiers in medicine (2026) - Case Report and Literature Review

Key Findings

  • The reported patient had recurrent generalized pain and weakness after mild exertion with repeatedly increased CK and hypokalemia.
  • Spontaneous, refractory hypokalemia from primary aldosteronism increased the risk of recurrent rhabdomyolysis until the endocrine cause was identified.

📋 Practice Implication: Recurrent or exertion-triggered rhabdomyolysis with hypokalemia should prompt evaluation for primary aldosteronism, especially when potassium depletion is spontaneous or refractory.

4. Acute kidney injury in rhabdomyolysis defined by serum creatine kinase ≥1000 IU/L: association with creatine kinase levels.

Postgraduate medical journal (2026) - Cohort Study

Key Findings

  • Among 855 adults with CK above 1000 IU/L, AKI developed in 368 patients (43%) and renal replacement therapy was required in 43 patients (5.0%).
  • CK levels above 5000 IU/L were associated with more severe AKI and greater dialysis requirement; among 269 AKI survivors followed at least three years, 87.4% fully recovered renal function.

📋 Practice Implication: CK above 5000 IU/L should raise the intensity of renal surveillance and fluid management, while prognosis counseling can note that most AKI survivors recover kidney function.

5. Early start of hemoadsorption is associated with improved kidney recovery in ICU patients with ischemic/reperfusion cause of rhabdomyolysis.

PloS one (2026) - Retrospective Cohort Study

Key Findings

  • Hemoadsorption with CRRT was associated with significant myoglobin reductions at all measured time points compared with CRRT alone.
  • Starting hemoadsorption within 12 hours was associated with shorter AKI duration, less acute kidney disease, and longer survival than late initiation (49.2 vs 15.3 days).

📋 Practice Implication: For severe ischemic/reperfusion rhabdomyolysis with AKI in the ICU, early nephrology and critical care escalation may affect the window for adjunctive hemoadsorption benefit.

💡 Summary

Recent rhabdomyolysis literature emphasizes early AKI risk stratification, medication-interaction vigilance, and rapid escalation for severe ICU presentations. The strongest current evidence links higher CK burden, admission metabolic markers, and early extracorporeal support timing with renal outcomes, while case-based data highlight preventable causes such as CDK4/6 inhibitor-statin combinations and primary aldosteronism-related hypokalemia.
