Hashimoto's thyroiditis masquerading as acute tubular injury and rhabdomyolysis.

Hashimoto's thyroiditis manifesting as hypothyroidism has been implicated in glomerular disorders due to autoantibody formation. Here we present the case of a 26-year-old male without any comorbidities presenting with easy fatiguability and weight gain for 2 months. He was found to have a creatinine of 2.1 mg/dL with a history of rhinitis treated with anti-histaminic three days prior to the hospital visit. He had symptoms of intermittent myalgia for the past two weeks. On laboratory evaluation, he was found to have raised CPK, elevated TSH, low normal T4, and positive anti-TPO and anti-Tg antibodies. Neck ultrasound revealed linear echogenic septations in the thyroid gland. Renal biopsy revealed acute tubular injury. Appropriate thyroxine supplementation was started and his creatinine decreased to 1.2 mg/dL after 1 month. It is important that clinicians should be aware of this rare kidney presentation in Hashimoto's thyroiditis.

Boswellia serrata intoxication manifesting with syndrome of inappropriate antidiuretic hormone secretion, hyponatremia, seizure, and rhabdomyolysis.

Boswellia serrata is an herbal extract from the Boswellia serrata tree that has anti-inflammatory and analgesic properties and alleviates pain caused by rheumatoid arthritis, gout, osteoarthritis, and sciatica. Syndrome of inappropriate antidiuretic hormone secretion accompanied by hyponatremia, seizures, and rhabdomyolysis as a manifestation of Boswellia serrata intoxication has not been reported previously. A 38-year-old female suffered clinically isolated syndrome and has since been regularly taking B. serrata capsules (200mg/d) to strengthen her immune system. She experienced hypersensitivity to light, ocular pain, nausea, dizziness, and lower limb weakness four days after receiving her first BNT162b2 vaccine dose, and she increased the dosage of B. serrata to five capsules (1000mg/d) one week after vaccination. After taking B. serrata at a dosage of 1000mg/d for 3 weeks, she was admitted to the intensive care unit because of a first, unprovoked generalized tonic-clonic seizure. The patient's workup revealed syndrome of inappropriate antidiuretic hormone secretion, which resolved completely upon treatment and discontinuation of B. serrata. In summary, B. serrata potentially causes syndrome of inappropriate antidiuretic hormone secretion when it is taken at high doses. Patients should not self-medicate.

Oral Dantrolene Reduces Myalgia and Hyperckemia in a Child with RYR1-Related Exertional Myalgia/Rhabdomyolysis.

RYR1-related exertional myalgia/rhabdomyolysis (ERM) is an underrecognized condition, which can cause limiting muscle symptoms, and may account for more than one-third of undiagnosed rhabdomyolysis cases. Dantrolene has shown promising results in controlling muscle symptoms in individuals with ERM, however, its use in children remains poorly documented. This case report presents the successful treatment of a 5-year-old patient with ERM using oral dantrolene. The patient experienced notable improvements, including a reduction in the frequency and intensity of myalgia episodes, no hospitalizations due to rhabdomyolysis, a substantial decrease in creatine phosphokinase (CPK) levels, and enhanced performance on the 6-minute walk test. The use of dantrolene was well-tolerated, and no significant adverse effects were observed. This report adds to the existing evidence supporting the effectiveness of oral dantrolene in managing ERM, and, to the best of our knowledge, this is the first report of the use of dantrolene in a pediatric patient for controlling anesthesia-independent muscle symptoms.

[Severe rhabdomyolysis associated with atorvastatin. Case report]. / Rabdomiólisis severa asociada a atorvastatina. Reporte de caso.

Background: Dyslipidemia is a risk factor for the development of atherosclerosis and ischemic heart disease. Statins are safe drugs that are part of the routine treatment in patients with Acute Myocardial Infarction (AMI), however, rhabdomyolysis associated with severe myonecrosis due to statins can occur and associated complications such as acute kidney injury increase mortality. The main objective of this article is to report the case of a critically ill patient with AMI who presented severe statin-associated rhabdomyolysis documented with muscle biopsy. Description of the case: A 54-year-old man who presented with AMI, cardiogenic shock, and cardiorespiratory arrest requiring cardiopulmonary resuscitation, fibrinolysis, and successful salvage coronary angiography. However, he presented severe rhabdomyolysis associated with atorvastatin that required suspension of the drug and multi-organ support in a Coronary Care Unit. Conclusions: The prevalence of statin-associated rhabdomyolysis is low, however, the late elevation of CPK above 10 times its upper normal value in those patients with successful percutaneous coronary angiography should promptly draw attention, generate a diagnostic approach towards non-traumatic acquired causes of rhabdomyolysis and assess the suspension of statins.

Introducción: la dislipidemia es un factor de riesgo para el desarrollo de ateroesclerosis y cardiopatía isquémica. Las estatinas son fármacos seguros que forman parte del tratamiento de rutina en el paciente con infarto agudo de miocardio (IAM). Sin embargo, la rabdomiólisis asociada a mionecrosis severa por estatinas puede presentarse y las complicaciones asociadas como la lesión renal aguda incrementan la mortalidad. El objetivo principal de este artículo es reportar el caso de un paciente críticamente enfermo con IAM que presentó rabdomiólisis severa asociada a estatinas documentada con biopsia muscular. Caso clínico: hombre de 54 años que presentó IAM, choque cardiogénico y paro cardiorrespiratorio, que ameritó reanimación cardiopulmonar, fibrinólisis y angiografía coronaria de rescate exitosa. Sin embargo, presentó rabdomiólisis severa asociada a atorvastatina que requirió de suspensión del fármaco y soporte multiorgánico en una unidad de cuidados coronarios. Conclusiones: la prevalencia de la rabdomiólisis asociada a estatinas es baja, sin embargo, la elevación tardía de la CPK por arriba de 10 veces su valor superior normal en aquellos pacientes con angiografía coronaria percutánea exitosa debe llamar la atención, generar un abordaje diagnóstico hacia causas adquiridas no traumáticas de rabdomiólisis y valorar la suspensión de estatinas.

Administration of a single dose of lithium ameliorates rhabdomyolysis-associated acute kidney injury in rats.

Rhabdomyolysis is characterized by muscle damage and leads to acute kidney injury (AKI). Clinical and experimental studies suggest that glycogen synthase kinase 3ß (GSK3ß) inhibition protects against AKI basically through its critical role in tubular epithelial cell apoptosis, inflammation and fibrosis. Treatment with a single dose of lithium, an inhibitor of GSK3ß, accelerated recovery of renal function in cisplatin and ischemic/reperfusion-induced AKI models. We aimed to evaluate the efficacy of a single dose of lithium in the treatment of rhabdomyolysis-induced AKI. Male Wistar rats were allocated to four groups: Sham, received saline 0.9% intraperitoneally (IP); lithium (Li), received a single IP injection of lithium chloride (LiCl) 80 mg/kg body weight (BW); glycerol (Gly), received a single dose of glycerol 50% 5 mL/kg BW intramuscular (IM); glycerol plus lithium (Gly+Li), received a single dose of glycerol 50% IM plus LiCl IP injected 2 hours after glycerol administration. After 24 hours, we performed inulin clearance experiments and collected blood / kidney / muscle samples. Gly rats exhibited renal function impairment accompanied by kidney injury, inflammation and alterations in signaling pathways for apoptosis and redox state balance. Gly+Li rats showed a remarkable improvement in renal function as well as kidney injury score, diminished CPK levels and an overstated decrease of renal and muscle GSK3ß protein expression. Furthermore, administration of lithium lowered the amount of macrophage infiltrate, reduced NFκB and caspase renal protein expression and increased the antioxidant component MnSOD. Lithium treatment attenuated renal dysfunction in rhabdomyolysis-associated AKI by improving inulin clearance and reducing CPK levels, inflammation, apoptosis and oxidative stress. These therapeutic effects were due to the inhibition of GSK3ß and possibly associated with a decrease in muscle injury.

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.

Ovariectomy exacerbates glycerol-induced acute kidney injury in rats / A ovariectomia intensifica a lesão renal aguda induzida pelo glicerol em ratas

Objective: This study aimed to evaluate the effects of ovariectomy on glycerol-induced renal changes in rats. Methods: Twenty-four female Wistar rats were submitted to ovariectomized (OVX) or sham surgery. One week after surgery, the animals received an intramuscular injection (8ml/kg) of 50% glycerol or saline (0.15 M) solution. These animals were divided into the following groups (n=6 per group): Sham, sham-operated female rats injected with saline; OVX, ovariectomized female rats injected with saline; Sham+Gly, sham-operated female rats injected with glycerol; OVX+Gly, ovariectomized female rats injected with glycerol. All rats were euthanized 3 days after the injections and the kidneys were removed for histological and immunohistochemical studies. Blood and urine samples were also collected for renal function studies. Results: The OVX+Gly group presented higher creatinine serum levels, as well as greater fractional excretion of sodium and urinary flow than the Sham+Gly group. Histological lesions and tubulointerstitial staining for macrophages, nuclear factor-kappa B, and nitrotyrosine were more pronounced in the renal cortex of the OVX+Gly group compared to the Sham+Gly group. Conclusion: We conclude that ovariectomy aggravated changes in renal function and structure in glycerol-induced acute kidney injury by the intensification of the proinflammatory tissue response.

Objetivo: Avaliar os efeitos da ovariectomia nas alterações renais induzidas pelo glicerol em ratas. Métodos: Vinte e quatro ratas Wistar foram submetidas à ovariectomia (OVX) ou cirurgia sham (intervenção falsa). Uma semana após a cirurgia, os animais receberam injeção intramuscular (8ml/kg) de glicerol a 50% ou solução salina (0,15 M). As ratas foram divididas nos seguintes grupos (n=6 por grupo): Sham, fêmeas sham-operadas e injetadas com solução salina; OVX, fêmeas ovariectomizadas e injetadas com solução salina; Sham+Gly, fêmeas sham-operadas e injetados com glicerol; OVX+Gly, fêmeas ovariectomizadas e injetadas com glicerol. Todas as ratas foram eutanasiadas 3 dias após as injeções e os rins foram removidos para estudos histológicos e imuno-histoquímicos. Amostras de sangue e urina também foram coletadas para estudos de função renal. Resultados: O grupo OVX+Gly apresentou maiores níveis séricos de creatinina, assim como maiores fração de excreção de sódio e fluxo urinário do que o grupo Sham+Gly. As lesões histológicas e imunomarcação tubulointersticial para macrófagos, fator nuclear-kappa B e nitrotirosina foram mais pronunciadas no córtex renal do grupo OVX+Gly em comparação ao grupo Sham+Gly. Conclusão: Concluímos que a ovariectomia agravou as alterações na função e estrutura renal, na lesão renal aguda induzida por glicerol, pela intensificação da resposta tecidual pró-inflamatória.

Síndrome neuroléptico maligno asociado con intoxicación aguda por un organofosforado: reporte de caso / Neuroleptic malignant syndrome associated with acute organophosphate poisoning: Case report

El síndrome neuroléptico maligno es una condición clínica rara y potencialmente letal que frecuentemente se asocia con el uso de antipsicóticos. En la literatura especializada se encontró únicamente un reporte de caso relacionado con la ingestión de organofosforados. Se presenta un paciente con un cuadro clínico correspondiente al síndrome neuroléptico maligno posterior a la ingestión de clorpirifós. Como resultado de un intento de suicidio con el mencionado organofosforado, el hombre de 57 años presentó deterioro agudo del estado de consciencia, evolución neurológica tórpida e inestabilidad autonómica asociada a rigidez e hipertermia persistentes, así como incremento de la creatina-fosfocinasa (creatine phosphokinase, CPK). Se le administró tratamiento con bromocriptina, con lo cual el cuadro clínico remitió, y fue dado de alta sin secuelas. El diagnóstico del síndrome neuroléptico maligno es clínico y debe contemplarse en cualquier caso de exposición a sustancias que puedan resultar en una desregulación de la neurotransmisión dopaminérgica, con el fin de iniciar el tratamiento oportuno y contrarrestar efectivamente los efectos.

Neuroleptic malignant syndrome is a rare and potentially fatal clinical condition frequently associated with the use of antipsychotics. In the literature, there is only one case report associated with the intake of organophosphates. We present the case of a patient who presented with a clinical picture compatible with neuroleptic malignant syndrome, after the ingestion of an organophosphate (chlorpyrifos). A 57-year-old man who consulted for attempted suicide, acute deterioration of consciousness, torpid neurological evolution, and associated autonomic instability associated with rigidity, persistent hyperthermia, and elevated CPK. Bromocriptine treatment was offered, which resolved the clinical picture. The association with the ingestion of an organophosphate was established, and he was discharged without sequelae. The diagnosis of neuroleptic malignant syndrome is clinical and should be considered in any case of exposure to substances that may lead to dysregulation of dopaminergic neurotransmission in order to initiate timely therapy and impact outcomes.

Characteristics of Snakebite-Related Infection in French Guiana.

Wound infection is frequently reported following snakebite (SB). This study is retrospective. It was conducted in the emergency department and the Intensive Care Unit (ICU) of Cayenne General Hospital between 1 January 2016 and 31 July 2021. We included 172 consecutive patients hospitalized for SB envenoming. All patients were monitored for wound infection. Sixty-three patients received antibiotics at admission (36.6%). The main antibiotic used was amoxicillin-clavulanate (92.1%). Wound infection was recorded in 55 cases (32%). It was 19% in grade 1, 35% in grade 2, and 53% in grade 3. It included abscess (69.1%), necrotizing fasciitis (16.4%), and cellulitis (21.8%). The time from SB to wound infection was 6 days (IQR: 3-8). The main isolated microorganisms were A. hydrophila and M. morganii (37.5% and 18.8% of isolated organisms). Surgery was required in 48 patients (28.1%), and a necrosectomy was performed on 16 of them (33.3%). The independent factors associated with snakebite-associated infection were necrosis (p < 0.001, OR 13.15, 95% CI: 4.04-42.84), thrombocytopenia (p = 0.002, OR: 3.37, 95% CI: 1.59-7.16), and rhabdomyolysis (p = 0.046, OR: 2.29, 95% CI: 1.02-5.19). In conclusion, wound infection following SB is frequent, mainly in grade 2 and 3 envenomed patients, especially those with necrosis, thrombocytopenia, and rhabdomyolysis. The main involved bacteria are A. hydrophila and M. morganii.

Rhabdomyolysis Episode in an Individual with McArdle's Disease after Low Aerobic Exercise.

McArdle's disease, known as blockage of muscle glycogen metabolism, is characterized by glycogen accumulation of chains in skeletal striated muscles. One of the typical symptoms of the disease is the feeling of intolerance to exercise. Severe muscle cram and contracture, which often cause stiffness, occur due to a lack of muscle energy substrate during the exercise. These factors can lead to muscle damage, myoglobinuria, and, in severe cases, renal failure and rhabdomyolysis. Rhabdomyolysis is a syndrome that presents injury and necrosis of muscle cells leading to the release of intracellular material to the circulatory system. The present study aimed to report rhabdomyolysis in an individual with McArdle's disease after exercise of walking with low intensity. Patient, aged 33 years, was treated in the emergency room of a hospital located in the State of Rio de Janeiro, Brazil. After performing a full lap on the block of home (~500 m in ~4 min 37 s), walking at a moderate speed (~6.5 km/h), the individual felt sick and was rescued, later being hospitalized. The examinations collected presented hematocrit (HCT) compatible with chronic disease anemia and myoglobinuria. The patient was discharged from the intensive care center on the 3rd day, after a 45% drop in creatine kinase. The patient described in the present study achieved full recovery. Attention to symptoms, early diagnosis, and immediate treatment made it possible to interrupt the development of complications caused by rhabdomyolysis, not allowing progression to acute renal failure.

Acute kidney injury associated with rhabdomyolysis in a patient with COVID-19.

Rhabdomyolysis is defined as the breakdown of skeletal muscle leading to the release of muscle contents into the extracellular fluid. Patients with rhabdomyolysis can be asymptomatic or have myalgia symptoms, weakness, myoglobinuria with dark urine, significant electrolyte imbalance, and acute kidney injury. Here we describe a case on acute kidney injury associated to rhabdomyolysis in a patient with COVID-19.

Polymyositis associated with brainstem signs in a dog

Background: Polymyositis is a generalized inflammatory myopathy which can lead to rhabdomyolysis. This affection may have several origins, including degenerative, metabolic, autoimmune, infectious, inflammatory, ischemic, traumatic, by drug use, induced by toxins and also of idiopathic origin. Diagnosis is made with seric dosage, electrodiagnostic tests and muscle biopsy. Lesions in the rostral oblong medulla may affect the central vestibular system, and there may be signs such as opisthotonos, nystagmus, and strabismus. The aim of this report is to describe a case of a mixed breed dog with manifestation of polymyositis associated with brainstem signs of probable idiopathic origin. Case: A 5-year-old mixed breed male dog was attended with opisthotonos episodes for 2 days, and pelvic limbs extension and thoracic limbs flexion that lasted 10 to 20 min at intervals of approximately 1 h. The animal was anorexic and had also presented one episode of emesis. Upon neurological examination, ventromedial strabismus and Horner's syndrome was observed on the right side, besides vertical nystagmus, flaccid tetraparesis and absence of proprioception in the four limbs. Biochemical analyses revealed creatine kinase (CK) increased (2,433.9 UI/L - reference: 1.5-28.4 UI/L), and urinalysis showed dark color and presence of occult blood without, however, erythrocyturia. Electrocardiogram (ECG) showed QS wave and deviation of the electrical axis. Treatment with prednisolone (1 mg/kg, BID), phenobarbital (2 mg/kg, BID), maropitant citrate (1 mg/kg in 2 doses), and crystalloid fluid therapy (50 mL/kg/day) were prescribed. On the 4th day, the dog was more active and feeding without a tube, so it recommended keep the treatment at home. On the 10th day, the animal had proprioception present on the 4 limbs and normorexia. Biochemical analyses and urinalysis showed no alterations, but normochromic normochromic anemia with thrombocytopenia and leukocytosis by neutrophilia showed in blood count exam. PCR to Ehrlichia canis, Hepatozoon sp., and Babesia canis resulted negative. On the 15th day, blood count, biochemical analyses and urinalysis showed no alterations. Neurological examination revealed only positional vertical nystagmus. which remained as a sequel. Discussion: Polymyositis may be accompanied by rhabdomyolysis, characterized by acute muscle necrosis, increased CK and myoglobinuria. The animal had polymyositis of acute onset, with myoglobinuria and elevated CK values, whose presentation included myalgia and muscle weakness. In humans, polymyositis is accompanied by changes in electrocardiographic tracing without clinical alterations. In dogs, the first report that showed cardiac involvement was compatible with myocarditis. The changes in ECG in the present case was attributed to failure in myocardial electrical conduction. The patient also showed signs of brainstem and central vestibular system injuries. Stress myopathy, intoxication, snakebite, infectious, and metabolic diseases were discarded leading to a clinical suspicion as idiopathic origin. Similar to a published case, the patient of this report received symptomatic and supportive treatment, being discharged from the hospital 20 days after the onset of clinical signs. Thus, polymyositis may be accompanied by signs indicative of brainstem injury. Patients with rhabdomyolysis require intense monitoring due to the high risk of developing acute renal failure. Since no causative agent was identified, symptomatic treatment combined with the prevention of possible complications were fundamental for the maintenance of the animal's life.

Downer cow syndrome causing rhabdomyolysis and acute renal failure in a 17-month-old Guzerá heifer / Síndrome da vaca caída causando rabdomiólise e insuficiência renal aguda em uma novilha Guzerá de 17 meses

The downer cow syndrome (DCS) is characterized by an alert cow showing inability or reluctance to stand for 12 hours or more. This paper reported clinical, laboratory, and pathological findings in a Guzerá heifer with rhabdomyolysis, pigmenturia and acute renal failure following DCS. A 17-month-old Guzerá heifer was transported via a 350-km ride in a truck and showed sternal recumbency and severe difficulty in standing and walking. Neurological examination was unremarkable, and the heifer presented normal response to cranial nerves and spinal cord tests. Rectal palpation revealed a 5-month gravid uterus. No other abnormalities were noted in the pelvis or around the coxofemoral joints. Biochemical abnormalities included extremely high muscular enzyme activities (creatine phosphokinase and aspartate aminotransferase) and high creatinine levels. Urinalysis revealed blackish and cloudy urine, proteinuria, and a positive occult blood test. Spinal cord ultrasonography showed no abnormalities. This report highlighted an uncommon clinical presentation (myoglobinuria) and pathological findings in a heifer with DCS as a consequence of severe compressive muscle damage. Practitioners and producers must be aware of the risk of careless road transportation for long distances of cattle, especially obese cows, avoiding unnecessary suffering and expenses due to DCS.

A síndrome da vaca caída (SVC) é caracterizada por um bovino alerta que mostra incapacidade ou relutância em permanecer em estação por 12 horas ou mais. O objetivo deste trabalho é relatar os achados clínicos, laboratoriais e patológicos em uma novilha Guzerá com rabdomiólise, pigmentúria e insuficiência renal aguda após a SVC. Uma novilha da raça Guzerá, de 17 meses de idade, foi transportada de caminhão por 350 km e apresentou decúbito esternal, grande dificuldade para assumir estação e caminhar. O exame neurológico não demonstrou alterações, e a novilha possuía resposta normal aos testes de nervos cranianos e medula espinhal. A palpação retal revelou útero grávido de cinco meses. Nenhuma outra anormalidade foi observada na pelve ou na região das articulações coxofemorais. As anormalidades bioquímicas incluíram atividades de enzimas musculares (creatina fosfoquinase e aspartato aminotransferase) extremamente aumentadas e níveis elevados de creatinina. A urinálise revelou urina enegrecida e turva, proteinúria e teste de sangue oculto positivo. O exame ultrassonográfico da medula espinhal não apresentou anormalidades. Este relato evidencia uma apresentação clínica (mioglobinúria) e achados patológicos incomuns em uma novilha com SVC em consequência de extensa lesão muscular compressiva. Veterinários e produtores devem estar atentos aos riscos do transporte rodoviário descuidado por longas distâncias de bovinos, especialmente vacas obesas, evitando assim sofrimento e despesas desnecessárias decorrentes da SVC.

[Rhabdomyolysis as the presentation form of COVID-19 infection. Report of one case]. / Rabdomiólisis como presentación inicial de COVID-19. Caso Clínico.

COVID-19 infection causes a systemic inflammatory response, which mainly presents as a febrile syndrome with respiratory involvement. We report a 37-year-old male who consulted for myalgia, nausea and epigastric pain lasting three days. On admission, he had crepitations at the lung bases. The initial laboratory showed a creatine kinase of 62,768 U/L, a LDH of 1,110 IU/L, a creatinine a 2.1 mg/dL, an aspartate aminotransferase of 1,347 IU/L, a D-dimer of 1,140 ng/mL, a ferritin of 1,201 ng/mL and a lymphocyte count of 810 cells/mm3. The chest CT scan was compatible with multifocal pneumonia, suggesting a COVID-19 infection. COVID-19 PCR was positive. The patient was managed with hydration, sodium bicarbonate, ceftriaxone, and azithromycin, with a good clinical response.

[Acute kidney injury caused by rhabdomyolysis as a SARS-CoV-2 infection manifestation. Report of one case]. / Insuficiencia renal aguda secundaria a rabdomiolisis como manifestación de infección por SARS-CoV-2.

SARS-CoV-2 infection has a wide spectrum of clinical manifestations secondary to the impairment of different organs, including kidney. Rhabdomyolysis is produced by disintegration of striated muscle and the liberation of its contents to the extracellular fluid and bloodstream. This may produce hydro electrolytic disorders and acute kidney injury. We report a 35-year-old female with a history of SARS-CoV-2 infection who was hospitalized because of respiratory failure and developed renal failure. The etiologic study showed elevated total creatine kinase levels and a magnetic resonance imaging confirmed rhabdomyolysis. The patient required supportive treatment with vasoactive drugs, mechanic ventilation and kidney replacement therapy. She had a favorable evolution with resolution of respiratory failure and improvement of kidney function.

[Late rhabdomyolysis secondary to SARS-CoV-2 infection]. / Rabdomiólisis tardía secundaria a infección por SARS-CoV-2.

SARS-CoV-2, the cause of 2019 novel coronavirus disease (COVID-19), has shown to produce a variety of extrapulmonary manifestations. Rhabdomyolysis due to SARS-CoV-2 infection has been reported mainly in the early course of the disease. In this report, we present the case of a female patient with confirmed SARS-CoV-2 infection who recovered from respiratory compromise and developed a late-onset rhabdomyolysis successfully managed with oral corticosteroids and aggressive hydration. Prompt recognition of this underdiagnosed entity could help prevent subsequent life-threatening complications.

El SARS-CoV-2, la causa de la enfermedad por el nuevo coronavirus de 2019 (COVID-19), ha demostrado producir una variedad de manifestaciones extra pulmonares. La rabdomiólisis debida a la infección por SARS-CoV-ha sido reportada principalmente en el curso temprano de la enfermedad. En el presente informe, presentamos el caso de una paciente con infección confirmada por SARS-CoV-2 que se recuperó de neumonía por COVID-19 y posteriormente desarrolló una rabdomiólisis de inicio tardío que fue manejada con éxito con corticosteroides orales e hidratación enérgica durante el curso de la hospitalización. El reconocimiento y diferenciación oportuna de esta subdiagnosticada entidad y las manifestaciones constitucionales usuales durante el COVID-19, podrían ayudar a prevenir y tratar tempranamente complicaciones posteriores potencialmente mortales.

Motor Vehicle Injury and Kidney Damage: Trauma, Rhabdomyolysis, Acute Kidney Injury and Beyond.

Clinical Background: Automobile accidents constitute one of the main causes of morbidity and mortality worldwide. Kidney injury related to automobile accidents occurs through several mechanisms. Among the mechanisms are direct traumatic injury, rhabdomyolysis, acute renal failure, hypovolemic shock, and others. Kidney injuries after traffic accidents can have different forms of clinical presentation, which can include morphological and functional changes of the organ. Epidemiology: Annually, approximately 1.35 million individuals are fatal victims of motor vehicle accidents. Challenges: It is of the utmost importance to recognize and adequately manage kidney injuries secondary to automobile events, since their timely identification can prevent permanent damage to the organ and, at times, save lives. Prevention and Treatment: An approach with a focus on traffic safety is ideal for all users. The cornerstones of this approach are safe roads and road shoulders, adequate speeds, safe vehicles, and trained drivers. Kidney injury and death due to this condition can be prevented by effective and integrated traffic legislation. After the occurrence of traffic accidents, effective emergency care is vital. Thus, a series of urgent actions are essential to provide assistance to the injured individual. In patients who are victims of car accidents and develop acute kidney injury and rhabdomyolysis, a timely diagnosis is extremely important to be able to offer assistance to the patient still in the early stages.
