Unusually high creatine kinase in a case of rhabdomyolysis without acute kidney injury: a case report

BackgroundWhile rhabdomyolysis frequently leads to hospital admissions, typically following trauma, recurrent occurrences are relatively rare, accounting for just 10% of cases. For young patients experiencing repetitive episodes without an apparent cause, a comprehensive investigation into the possible etiologies is crucial. Recognizing the atypical nature of recurrent rhabdomyolysis is crucial and a thorough workup encompassing evaluations for potential endocrine, inflammatory, and metabolic etiologies is recommended. Additionally, acute kidney injury is a common complication with severe rhabdomyolysis, hence early recognition and intervention is crucial.Case DescriptionHerein we present a case of a 30-year-old young African American male patient with recurrent rhabdomyolysis with the highest ever reported creatine kinase (CK) to our knowledge. A notable aspect of this case is the surprising absence of acute kidney injury, despite the severity of CK elevation. We also delve into the extensive workup done for rhabdomyolysis of unclear etiology.ConclusionsOur case underscores the importance of looking into non-traumatic factors behind recurrent rhabdomyolysis, especially in young patients. We also stress the significance of early detection and intervention, showcasing the potential to prevent acute kidney injury even in the presence of markedly elevated CK levels. Timely recognition and appropriate management can prove instrumental in mitigating the severity of complications associated with rhabdomyolysis.
