Analysis of physiological markers and risk factors for the development of rhabdomyolysis in military personnel: a systematic review.

OBJECTIVES

To analyze case reports with individual patient data belonging to the Armed Forces submitted to specific physical or military combat training that was affected by rhabdomyolysis and identify factors that influenced the diagnosis and clinical evolution of the syndrome.

CONTENT

We conducted a systematic review following the PRISMA guidelines and registered on PROSPERO (CRD42021242465). We searched MedLine (via PubMed), Scopus, Cochrane, Lilacs, SciELO, CINAHL, Web of Science, SPORTDiscus, ScienceDirect, and PEDro databases for studies that reported cases of military personnel affected by rhabdomyolysis.

SUMMARY AND OUTLOOK

Thirteen studies met the inclusion criteria. Forty-nine individual cases of rhabdomyolysis were analyzed. From them, it was possible to identify several associated factors, which were responsible for developing rhabdomyolysis in military personnel. Thirty military personnel (60%) practiced physical training and 20 (40%) practiced specific military combat training. The creatine kinase (CK) peak ranged from 1,040 to 410,755 U/L, with an average of 44.991 U/L, and 14 (28%) of the cases reported alteration of renal function and four militaries (8%) evolved to death condition. Physical activities performed strenuously and without proper planning conditions such as room temperature, the period without adequate water intake, the amount of equipment used during the activity contributed to the development of rhabdomyolysis in the cases of military personnel analyzed in the present study. Therefore, it is recommended that future studies investigate the relationship between the prevalence of rhabdomyolysis cases and the severity of its consequence when associated with progressive methods of training, hydration control, acclimatization to austere environments, monitoring for the existence of hereditary diseases, and control of the use of supplementary nutritional substances.
