Rhabdomyolysis - a Study of Patients and Laboratory Values to Guide Treatment

Completed
Conditions
Rhabdomyolysis
Registration Number
NCT04118608
Lead Sponsor
Oslo University Hospital
Brief Summary

Rhabdomyolysis is a potentially life-threatening syndrome characterized by breakdown of skeletal muscle, and leakage of intracellular substances such as myoglobin and creatine kinase (CK) into the circulation. The aetiological spectrum of rhabdomyolysis is extensive, and the clinical spectrum varies from a transient subclinical increase in CK activity to acute kidney injury (AKI) as a serious complication. There are no large prospective studies and only a few retrospective studies on rhabdomyolysis.

Detailed Description

Rhabdomyolysis is a potentially life-threatening syndrome characterized by breakdown of skeletal muscle, and leakage of intracellular substances such as myoglobin and creatine kinase (CK) into the circulation. The aetiological spectrum of rhabdomyolysis is extensive, and the clinical spectrum varies from a transient subclinical increase in CK activity to acute kidney injury (AKI) as a serious complication. There are no large prospective studies and only a few retrospective studies on rhabdomyolysis.

The project will give much needed information about incidence, aetiologies and the clinical course of rhabdomyolysis. The main objective will be to study rhabdomyolysis with focus on the development of AKI and how laboratory values can guide treatment, and thus act as basis for guidelines. More knowledge is needed about rhabdomyolysis and long-term kidney injury, and the study will aim to identify a risk population for later kidney injury, thus being able to refer this group to follow-up and prevent further injury. On the other hand, exercise-induced rhabdomyolysis patients are probably hospitalized more than necessary these days, and over-treatment could be prevented if better guidelines were obtained. The possible cardiotoxicity of myoglobin needs further study, and would benefit the patient group but also fill a knowledge gap for the clinicians. Therefore, this project will ideally obtain new knowledge for the health services, potentially improve existing practice and fill important knowledge gaps.

Study & Design

Study Type
OBSERVATIONAL
Study Design
Not specified
Primary Outcome Measures
NameTimeMethod
Development of Acute Kidney Injury (AKI)Change of creatinine from baseline (KDIGO 2012 guidelines) through hospitalization (average 1 week)

AKI will be defined according to KDIGO 2012 guidelines

Kidney function after three months and development of Chronic Kidney Disease (CKD)3 months

Change in kreatinine and/or eGFR. CKD classifications followed KDIGO stages I-V

Secondary Outcome Measures
NameTimeMethod
Other complicationsDuring hospitalization (average 1 week)

Other complications including death

Risk stratification based on Myoglobin/Creatine kinase ratioChange of creatinine from baseline (KDIGO 2012 guidelines) through hospitalization (average 1 week)

Risk of AKI (see above) can be predicted based on this ratio

Association between rhabdomyolysis, elevated cardiac enzymes and the effect on myocardium.Through hospitalization (average 1 week)

Increased Troponin T levels and findings on echocardiography with strain and in some cardiac IMR

Risk stratification based on Myoglobin and Creatine kinaseThrough hospitalization (average 1 week)

See if risk of AKI (see above) can be predicted based on this
