Exertional rhabdomyolysis

Joseph J Knapik, Francis G O'Connor
Exertional rhabdomyolysis (ER) is a medical condition whereby damage to skeletal muscle is induced by excessive physical activity in otherwise healthy individuals. The individual performs so much activity that he/ she presumably depletes local muscle energy stores and muscle cells are unable to maintain cellular integrity, resulting in cell damage and the release of cellular contents, with resultant secondary complications. In the military services, the incidence of ER appeared to increase in the period 2004 to 2015...

A previous report suggests a substantial incidence of exertional rhabdomyolysis (ER) in Arabian horses performing endurance racing. This study compared formalin histopathology and clinical and metabolic responses to a standardised field exercise test (SET) between Arabians with and without ER. Arabian horses with (n = 10; age 15.4 ± 5.6 years) and without (n = 9; 12.9 ± 6.1 years) prior ER were stall-rested for 24-48 h, after which paired ER and control horses were fitted with a telemetric ECG and performed a 47 min submaximal SET...

Mutations in the skeletal muscle ryanodine receptor (RYR1) gene are associated with a wide spectrum of inherited myopathies presenting throughout life. Malignant hyperthermia susceptibility (MHS)-related RYR1 mutations have emerged as a common cause of exertional rhabdomyolysis, accounting for up to 30% of rhabdomyolysis episodes in otherwise healthy individuals. Common triggers are exercise and heat and, less frequently, viral infections, alcohol and drugs. Most subjects are normally strong and have no personal or family history of malignant hyperthermia...

Phosphoglycerate mutase enzyme deficiency in muscle causes a metabolic myopathy (glycogen storage disease X) characterized by exertional muscle contractures, weakness, hyperCKemia, and myoglobinuria. Six different autosomal recessive variants in PGAM-M have been described thus far (Salameh et al., 2013). In this case report, we report a novel disease-causing variant. A 52-year-old African-American woman presented with exertional muscle contractures, myalgias, and weakness since childhood including an episode of rhabdomyolysis...

Rhabdomyolysis is a rare but potentially fatal complication of status asthmaticus. Since the first case was reported in 1978, only a few dozen cases have been described till date. We performed a literature review with the aim to characterize the pathophysiological basis of the occurrence of rhabdomyolysis in patients with status asthmaticus. Excessive exertion of respiratory muscles, hypoxia and acidosis, electrolyte imbalance, infections, some drugs used for asthma control, use of mechanical ventilation, prolonged cardiopulmonary resuscitation, higher age of the patient and some underlying diseases or genetic factors appear to be involved in its causation...

PURPOSE OF REVIEW: This article reviews adult presentations of the major congenital myopathies - central core disease, multiminicore disease, centronuclear myopathy and nemaline myopathy - with an emphasis on common genetic backgrounds, typical clinicopathological features and differential diagnosis. RECENT FINDINGS: The congenital myopathies are a genetically heterogeneous group of conditions with characteristic histopathological features. Although essentially considered paediatric conditions, some forms - in particular those due to dominant mutations in the skeletal muscle ryanodine receptor (RYR1), the dynamin 2 (DNM2), the amphiphysin 2 (BIN1) and the Kelch repeat-and BTB/POZ domain-containing protein 13 (KBTBD13) gene - may present late into adulthood...

BACKGROUND: Exertional rhabdomyolysis (ER) is the breakdown of skeletal muscle tissue following intense physical activity that results in impairment of the cell membrane, which allows intracellular contents to be released into the bloodstream. Signs and symptoms include myalgia, myoglobinuria and increased creatine kinase (CK) levels. Athletes are vulnerable to this condition due to their increased level of physical activity. The severity and effects of this condition vary between individuals; however, all athletes are at risk of significant muscle damage, renal failure and perhaps death if not recognized and treated quickly...

BACKGROUND: Studies have suggested that sickle cell trait elevates the risks of exertional rhabdomyolysis and death. We conducted a study of sickle cell trait in relation to these outcomes, controlling for known risk factors for exertional rhabdomyolysis, in a large population of active persons who had undergone laboratory tests for hemoglobin AS (HbAS) and who were subject to exertional-injury precautions. METHODS: We used Cox proportional-hazards models to test whether the risks of exertional rhabdomyolysis and death varied according to sickle cell trait status among 47,944 black soldiers who had undergone testing for HbAS and who were on active duty in the U...

Recurrent exertional rhabdomyolysis (RER) in Thoroughbred and Standardbred racehorses is characterized by episodes of muscle rigidity and cell damage that often recur upon strenuous exercise. The objective was to evaluate the importance of genetic factors in RER by obtaining an unbiased estimate of heritability in cohorts of unrelated Thoroughbred and Standardbred racehorses. Four hundred ninety-one Thoroughbred and 196 Standardbred racehorses were genotyped with the 54K or 74K SNP genotyping arrays. Heritability was calculated from genome-wide SNP data with a mixed linear and Bayesian model, utilizing the standard genetic relationship matrix (GRM)...

OBJECTIVE: To outline a 4-phase progressive program that safely and successfully enabled athletes to return to sport without recurrence of exertional rhabdomyolysis symptoms. BACKGROUND: In January 2011, a large cluster of National Collegiate Athletic Association Division I football athletes were evaluated and treated for exertional rhabdomyolysis. After the athletes were treated, the athletic trainers and sports medicine providers were challenged to develop a safe return-to-play program because of the lack of specific reports in the medical literature to direct such activities...

BACKGROUND: Heat stroke is a life-threatening condition with exertional heat stroke occurring frequently among soldiers and athletes. Because of its common occurrence, many military trainees practice preventive measures prior to any activity requiring severe exertion. Although it is said to be common in practice, different presentations of heat stroke are scarcely described in literature. CASE PRESENTATION: We describe a case of an exertional heat stroke in a 23-year-old male Sinhalese soldier who developed early changes of renal failure, liver failure and rhabdomyolysis...

BACKGROUND: Heat stroke, heat-related illness, and malignant hyperthermia all present with hyperthermia. The former two are common presentations in the emergency department (ED). On the other hand, malignant hyperthermia (MH) is an uncommon but equally dangerous condition that requires prompt recognition and specific treatment with dantrolene sodium and avoidance of certain medications to reduce morbidity and mortality. Recent research focusing on nonanesthetic or exercise-induced MH has demonstrated a relationship between certain gene mutations and malignant hyperthermia susceptibility...

Among active component members of the U.S. Army, Navy, Air Force, and Marine Corps in 2015, there were 456 incident episodes of rhabdomyolysis likely due to physical exertion or heat stress ("exertional rhabdomyolysis"). Annual rates of incident diagnoses of exertional rhabdomyolysis increased 17% between 2014 and 2015. In 2015, the highest incidence rates occurred in service members who were male; younger than 20 years of age; black, non-Hispanic; members of the Marine Corps and Army; recruit trainees; and in combat-specific occupations...
