Perioperative Rhabdomyolysis in Obese Individuals Undergoing Bariatric Surgery: Current Status

One potential complication in bariatric surgery is rhabdomyolysis, which is a condition involving muscle tissue damage that can significantly impact a patient's health. The causes of rhabdomyolysis can be broadly classified into two major categories: traumatic and non-traumatic. Early investigations into the development of intraoperative rhabdomyolysis in bariatric surgery identified the main risk factors as tissue compression-primarily affecting the lower extremities, gluteal muscles, and lumbar region-as well as prolonged periods of immobilization. Clinically, rhabdomyolysis is typically suspected when a patient presents with muscle pain, weakness, and potentially dark urine or even anuria. However, the most reliable biomarker for rhabdomyolysis is elevated serum creatine kinase levels. The primary goal in managing hydration is to correct intravascular volume depletion, with solutions such as Lactated Ringer's or 0.9% saline being appropriate options for resuscitation. Perioperative diagnosis of rhabdomyolysis poses a significant challenge for anesthesiologists, requiring a high degree of clinical suspicion, particularly in bariatric patients. In this vulnerable population, prevention is crucial. The success of treatment depends on its early initiation; however, there are still significant limitations in the therapies available to prevent renal injury secondary to rhabdomyolysis.

Postoperative rhabdomyolysis following otoplasty: an autopsy case report

Postoperative rhabdomyolysis is a significant complication that can arise from prolonged surgery, causing potential harm to the kidneys and leading to acute renal failure. Despite its importance, the incidence of rhabdomyolysis following ear reconstruction surgery remains undocumented in the literature. In this report, we present a case study of a male patient in his forties who underwent otoplasty for ear reconstruction after the amputation of his right ear due to a physical assault. The surgery lasted for 8 h under general anesthesia, and unfortunately, the patient developed postoperative rhabdomyolysis, which resulted in severe renal failure and ultimately an unrecoverable cardiac arrest, leading to his death. The autopsy findings indicated no identifiable lesions except for organ congestion, while histopathology revealed acute tubular necrosis of the kidney and muscle rhabdomyolysis. Previous literature has explored the association between surgical duration, location, and rhabdomyolysis, underscoring that this condition is an infrequent yet preventable consequence of prolonged surgery. The co-occurrence of rhabdomyolysis and acute renal injury in this case suggests the presence of comorbidity, emphasizing the need for prompt action to mitigate the negative consequences of rhabdomyolysis. Awareness and early intervention are crucial in preventing and managing this condition effectively.

Creatine Kinase Surge: Levetiracetam-Induced Rhabdomyolysis

Rhabdomyolysis is the breakdown of muscle cells secondary to both traumatic and non-traumatic causes. The lysing of the muscle cells can lead to the release of cell contents that can lead to acute injury and other life-threatening conditions. Levetiracetam is an anticonvulsant commonly used in generalized and partial tonic-clonic seizures. Well-known side effects include agitation, depression, anxiety, irritability, rash, and somnolence; however, there are an increasing number of case reports that report rhabdomyolysis secondary to antiepileptic use. We present a case of a 27-year-old male with new-onset seizures who was started on levetiracetam therapy and found to have elevated creatine kinase (CK), which decreased only with tapering of the drug. Our case displays the importance of considering levetiracetam as a cause of rhabdomyolysis, supporting this rare side effect of the antiseizure medication. Rhabdomyolysis is a potentially life-threatening condition that can lead to irreversible renal damage if not managed properly.

A systematic review of the drug-drug interaction between Statins and Quinolones

BACKGROUND

Statins are widely used in cardiovascular disease (CVD) as a common lipid-lowering drug, while quinolones are widely used for the treatment of infectious diseases. It is common to see CVD in combination with infectious diseases, therefore it is often the case that statins and quinolones are used in combination. Data suggest combinations of statin and quinolone may be associated with potentially life-threatening myopathy, rhabdomyolysis and acute hepatitis. This systematic review aims to characterize data regarding patients affected by the statin-quinolone interaction.

METHODS

The purpose of this systematic review was to collect and evaluate the evidence surrounding statin-quinolone drug interactions and to discuss related risk mitigation strategies. The following databases were searched: PubMed (Medline), Embase, Scopus, and Cochrane Library. The systematic electronic literature search was conducted with the following search terms. In this study, three types of search terms were used: statins-related terms, quinolones-related terms, and drug interactions-related terms.

RESULTS

There were 16 case reports that met the criteria for qualitative analysis. Patients were involved in the following adverse reactions: rhabdomyolysis (n = 12), acute hepatitis (n = 1), muscle weakness (n = 1), hip tendinopathy (n = 1), or myopathy (n = 1). In the included literature, patients vary in the dose and type of statins they take, including simvastatin (n = 10) at a dose range of 20-80 mg/d and atorvastatin (n = 4) at a dose of 80 mg/d. There were 2 patients with unspecified statin doses, separately using simvastatin and atorvastatin. The quinolones in combination were ciprofloxacin (n = 9) at a dose range of 800-1500 mg/d, levofloxacin (n = 6) at a dose range of 250-1000 mg/d, and norfloxacin (n = 1) in an unspecified dose range. 81% of the case patients were over 60 years of age, and about 1/3 had kidney-related diseases such as diabetic nephropathy, post-transplantation, and severe glomerulonephritis. Nearly two-third of the patients were on concomitant cytochrome P450 3A4 (CYP3A4) inhibitors, P-glycoprotein (P-gp) inhibitors, or organic anion transporting polypeptide 1B1 (OATP1B1) inhibitors.

CONCLUSION

Patients treated with statin-quinolone combination should be monitored more closely for changes in aspartate aminotransferase or creatine kinase (CK) levels, and muscle symptoms, especially in patients with ciprofloxacin or levofloxacin, with simvastatin and high-dose atorvastatin, over 60 years of age, with kidney-related diseases, and on concomitant CYP3A4 inhibitors.

Ritodrine-induced rhabdomyolysis and psychiatric symptoms: a case report and literature review

BACKGROUND

Ritodrine hydrochloride, a β2-adrenergic agonist, has been widely used in Asia and Europe to treat preterm labor in pregnant women. It has some typical side effects, such as palpitations, pulmonary edema, and hypokalemia. Here, we report a case of rhabdomyolysis and psychiatric symptoms might be associated with intravenous ritodrine.

CASE PRESENTATION

A 32-year-old Chinese primigravida woman who was pregnant with twins by in vitro fertilization-embryo transfer was diagnosed with placenta previa and threatened abortion at 21 gestational weeks (GW). The patient was then treated with ritodrine hydrochloride. The initial dose of ritodrine was 150 μg/min, gradually increasing to 360 μg/min at 23^5/7 GW and 400 μg/min at 27^1/7 GW. Magnesium sulfate was added to the ritodrine regimen at 21^5/7 GW in dosage of 1-2 g/h. Psychiatric symptoms appeared at 24^5/7, 26^5/7, and 27^3/7 GW, manifesting as depression, anxiety, and suicidal tendencies. Severe muscle pain in her limbs and general weakness appeared after six weeks of ritodrine administration, which might have been a sign of rhabdomyolysis resulting from ritodrine administration. After ceasing the administration of ritodrine, the muscle pain and relevant data from laboratory tests on the patient were significantly improved, and her mood was stable. It is worth noting that this is the first time to report psychiatric symptoms may associated with the administration of ritodrine. In addition, we reviewed and analyzed six reported cases of rhabdomyolysis caused by ritodrine.

CONCLUSION

Our results suggest that we should pay more attention to the risk of rhabdomyolysis and psychiatric symptoms induced by intravenous ritodrine hydrochloride, especially in patients with a history of neuromuscular disorder, or concomitant use of magnesium sulfate.

The management and diagnosis of rhabdomyolysis-induced acute kidney injury: a case study

Rhabdomyolysis is characterised by a rapid dissolution of damaged or injured skeletal muscle that can be the result of a multitude of mechanisms. It can range in severity from mild to severe, leading to multi-organ failure and death. Rhabdomyolysis causes muscular cellular breakdown, which can cause fatal electrolyte imbalances and metabolic acidosis, as myoglobin, creatine phosphokinase, lactate dehydrogenase and other electrolytes move into the circulation; acute kidney injury can follow as a severe complication. This article reflects on the case of a person who was diagnosed with rhabdomyolysis and acute kidney injury after a fall at home. Understanding the underpinning mechanism of rhabdomyolysis and the associated severity of symptoms may improve early diagnosis and treatment initiation.
