Rhabdomyolysis and acute kidney injury: creatine kinase as a prognostic marker and validation of the McMahon Score in a 10-year cohort: A retrospective observational evaluation

BACKGROUND: High-volume fluid resuscitation and the administration of sodium bicarbonate and diuretics have a theoretical renoprotective role in patients at high risk of acute kidney injury (AKI) following rhabdomyolysis. Abnormally elevated creatine kinase has previously been used as a biological marker for the identification of patients at high risk of AKI following rhabdomyolysis. OBJECTIVE: To assess the sensitivity and specificity of plasma creatine kinase (admission and peak values) for the prediction of AKI requiring renal replacement therapy (RRT) or of death in patients with confirmed rhabdomyolysis. To compare the diagnostic performance of creatine kinase with the McMahon score. DESIGN: Retrospective observational study. Data collection included McMahon and Acute Physiology and Chronic Health Evaluation II (APACHE II) scores; daily creatine kinase; daily creatinine and electrolytes; ICU length of stay and mortality. SETTING: Neurosciences and Trauma Critical Care Unit (Cambridge, UK). PATIENTS: In total, 232 adults with confirmed rhabdomyolysis (creatine kinase > 1000 Ul−1) admitted to Neurosciences and Trauma Critical Care Unit between 2002 and 2012. MAIN OUTCOME MEASURES: AKI, RRT and mortality. RESULTS: Forty-five (19%) patients developed AKI and 29 (12.5%) patients required RRT. Mortality was significantly higher in patients who developed AKI (62 vs. 18%, P

Abstract Malignant hyperthermia (MH) is a rare, heterogenic syndrome leading to potentially life-threatening skeletal muscle hypermetabolism following exposure to inhalational anesthetics and succinylcholine. In more than 50% of affected individuals a pathogenic variant in the RYR1 gene coding for the sarcoplasmic reticulum calcium channel is responsible for the underlying pathology of uncontrolled calcium liberation. While the genetic prevalence of MH is as high as 1 : 2750, the incidence of clinical MH reactions is considerably lower, suggesting a dominant pattern of inheritance with incomplete penetrance. D...

Malignant hyperthermia (MH) is classically described as an autosomal dominant myopathy involving type 1 ryanodine receptor (RYR1), which predisposes affected individuals to potentially life-threatening sequela when exposed to volatile anesthetics or depolarizing skeletal muscle relaxants, such as succinylcholine. In cases where malignant hyperthermia or anesthetic induced rhabdomyolysis (AIR) is triggered, significant morbidity and often mortality can result. In an ambulatory anesthetic setting, family history of malignant hyperthermia and history of anesthetic-related events is typically utilized to screen out susceptible individuals.

Mutations in RYR1, the gene encoding the sarcoplasmic reticulum (SR) type 1 ryanodine receptor (RyR1), have emerged as the most common genetic cause of non-dystrophic neuromuscular disorders in recent years.[1] RYR1 mutations give rise to a wide variety of myopathies presenting throughout life [2], ranging from early-onset congenital myopathies (for review, Jungbluth et al. [3]) to episodic manifestations in adulthood such as exertional rhabdomyolysis (RM), malignant hyperthermia during anesthesia with susceptibility proven by an in vitro contracture test (MH) and periodic paralysis [4] in otherwise healthy individuals.

Abstract An 8-year-old, spayed female Chihuahua mixed breed dog was presented for dyspnea and was subsequently mechanically ventilated. Propofol was utilized as part of the anesthetic protocol. The dog developed rhabdomyolysis, myoglobinuria, cardiac arrhythmias, liver enzyme elevation, and methemoglobinemia. Propofol was discontinued and N-acetylcysteine was administered after which the clinical signs resolved. PMID: 30410181 [PubMed - in process]

Previous epidemiologic studies have shown no association between cancer and amyotrophic lateral sclerosis. Colorectal cancer arising in patients with amyotrophic lateral sclerosis has rarely been reported. Here, we report a case involving rectal cancer ar...
