Idiopathic Benign Hyper-CK-Emia

Area of Science:

• Rheumatology
• Clinical Medicine
• Biochemistry

Background:

• Persistent elevation of serum creatine (phospho) kinase (CK) levels, or hyper-CK-emia, frequently prompts rheumatology consultation.
• Idiopathic benign hyper-CK-emia is a recognized condition in medical literature but often underdiagnosed by primary care physicians.
• Early recognition is crucial for differentiating benign cases from more serious myopathies.

Observation:

• A descriptive analysis of 16 consecutive adult patients with idiopathic benign hyper-CK-emia was conducted.
• Patients were evaluated at a tertiary care Rheumatology Clinic in Bismarck, North Dakota.
• The study observed the clinical course and laboratory findings associated with this condition.

Findings:

• The study identified idiopathic benign hyper-CK-emia in 16 adult patients.
• The condition was characterized by persistent elevation of serum CK levels without an identifiable underlying cause.
• The observed course of the condition in these patients was benign.

Implications:

• Increased awareness among primary care physicians regarding idiopathic benign hyper-CK-emia is warranted.
• This condition's benign nature necessitates distinguishing it from potentially serious neuromuscular disorders.
• This report represents the first documentation of idiopathic benign hyper-CK-emia in North Dakota, contributing to broader medical literature.
