Background: Exercise-induced rhabdomyolysis occurs in special situations, such as strenuous exercise or training of troops, and early diagnosis is difficult without suspicion. We investigated the clinical characteristics of exercise-induced rhabdomyolysis, and tried to identify factors associated with acute kidney injury, that often occurs as a complication.
Methods: One hundred and forty-two rhabdomyolysis cases were selected by reviewing hospital records of Combat and Auxiliary Police patients who were hospitalized at the National Police Hospital from 2007 to 2015. The records were analyzed based on the laboratory findings and clinical manifestations. The factors contributing to acute kidney injury were confirmed by comparing two groups: one with an elevated serum creatinine levels and one with a serum creatinine within the normal limits.
Results: The elevated serum creatinine group had a significantly higher uric acid and phosphate level and a lower albumin and sodium than the group with a normal serum creatinine. Logistic regression analysis revealed that high blood phosphate levels and low urine acidity are associated with a higher creatinine level.
Conclusion: The increase in serum creatine phosphokinase cannot predict the severity of the disease and the risk of complications. General body aches or pain in the trunk associated with a full body workout is thought to increase the likelihood of progression to acute kidney injury. There needs to be more careful observation in cases of high blood phosphate level and low urine acidity.
