Rhabdomyolysis as the main manifestation of coronavirus disease 2019

Profound Rhabdomyolysis and Viral Myositis Due to SARS-CoV-2: A Case Report

The novel SARS-CoV-2 introduced several new inflammatory conditions including SARS-CoV-2-associated rhabdomyolysis and viral myositis. We present a 22-year-old man who noted a week of cough followed by myalgias, dark-colored urine, and decreased oral intake. He was found to have acute nontraumatic rhabdomyolysis after an acutely positive SARS-CoV-2 test. Initial creatine kinase (CK) level was above the reference range as were liver enzymes reflective of muscle breakdown. Treatment involved fluid resuscitation and pain control, with close monitoring of kidney, liver, and skeletal markers over five days of hospitalization till there was clinical and symptomatic improvement.

NEW PREDICTIVE BIOMARKERS FOR SCREENING COVID-19 PATIENTS WITH RHABDOMYOLYSIS IN COMBINATION WITH CYSTATIN C

ABSTRACT

Purpose: Cystatin C (CysC) has been linked to the prognosis of corona virus disease 2019 (COVID-19). The study aims to investigate a predictor correlated with CysC screening for poor prognosis in COVID-19 patients combined with skeletal muscle (SKM) impairment and rhabdomyolysis (RM). Methods: A single-center retrospective cohort analysis was carried out. Demographic information, clinical data, laboratory test results, and clinical outcome data were gathered and analyzed. Results: According to the inclusion and exclusion criteria, 382 patients were included in this study. The subjects were divided into three groups based on CysC tertiles. Multivariate analysis revealed that SaO 2 (hazard ratio [HR], 0.946; 95% confidence interval [CI], 0.906-0.987; P = 0.011), CysC (HR, 2.124; 95% CI, 1.223-3.689; P = 0.008), aspartate aminotransferase (AST) (HR, 1.009; 95% CI, 1.000-1.018; P = 0.041), and hypersensitive C-reactive protein (HR, 1.005; 95% CI, 1.000-1.010; P = 0.045) were significantly associated with survivals. The area under curve (AUC) in the model characterized by RM incidence was 0.819 (0.698-0.941), as shown by CysC receiver operating characteristic curves. LDH*CysC and AST*CysC had better predictive values than CysC and the best prediction for RM, with an AUC of 0.880 (0.796,0.964) for LDH*CysC ( P < 0.05, vs CysC) and 0.925 (0.878,0.972) for AST*CysC ( P < 0.05, vs CysC). Conclusion: CysC is an essential evaluation indicator for COVID-19 patients' prognosis. AST*CysC and LDH*CysC have superior predictive value to CysC for SKM, RM, and death, and optimal classification for RM.

Blood Features Associated with Viral Infection Severity: An Experience from COVID-19-Pandemic Patients Hospitalized in the Center of Iran, Yazd

Pandemics such as coronavirus disease 2019 (COVID-19) can manifest as systemic infections that affect multiple organs and show laboratory manifestations. We aimed to analyze laboratory findings to understand possible mechanisms of organ dysfunction and risk stratification of hospitalized patients in these epidemics. Methods. This retrospective study was conducted among patients admitted to COVID-19 referral treatment center, Shahid Sadoughi Hospital, Yazd, Iran, from April 21 to November 21, 2021. It was the fifth peak of COVID-19 in Iran, and Delta (VOC-21APR-02; B.1-617.2) was the dominant and most concerning strain. All cases were positive for COVID-19 by RT-PCR test. Lab information of included patients and association of sex, age, and outcome were analyzed, on admission. Results. A total of 466 COVID-19 patients were included in the study, the majority of whom were women (68.9%). The average age of hospitalized patients in male and female patients was 57.68 and 41.32 years, respectively (p < 0.01). During hospitalization, abnormality in hematological and biochemical parameters was significant and was associated with the outcome of death in patients. There was incidence of lymphopenia, neutrophilia, anemia, and thrombocytopenia. The changes in neutrophil/lymphocyte (N/L) and hematocrit/albumin (Het/Alb) ratio and potassium and calcium levels were significant. Conclusion. Based on these results, new biochemical and hematological parameters can be used to predict the spread of infection and the underlying molecular mechanism. Viral infection may spread through blood cells and the immune system.

Urea/Creatinine Ratio's Correlation with Creatine Kinase Normalization in Pediatric COVID-19 Patients with Myositis: Evaluating Prognostic and Predictive Value

Coronavirus disease 2019 (COVID-19) has been chiefly linked with substantial respiratory complications. However, emerging studies have brought attention to the occurrence of severe muscle inflammation (myositis) related to COVID-19, potentially leading to multi-organ failure and increased mortality. Myositis is generally characterized by heightened serum creatine kinase (CK) levels. Acute myositis is characterized by an infiltration of viruses into calf muscle fibers, which may cause a subsequent inflammatory response leading to calf muscle pain. Symptomatic and supportive management, along with explanation and reassurance, is all that is required in managing this condition. While the association between myositis and severe outcomes has been recognized in adults, it remains less understood in the pediatric population. The current retrospective study, conducted at Policlinico San Marco University Hospital in Catania, aimed to analyze clinical and laboratory factors associated with myositis in pediatric patients with SARS-CoV-2 infection. Between January 2022 and January 2023, ten pediatric patients diagnosed with myositis and SARS-CoV-2 infection were evaluated. The study highlighted clinical manifestations such as fever, calf muscle pain, and abnormal gait. Lab results showed elevated CK levels among other findings. All patients underwent treatment, with the majority recovering without complications. A notable correlation was observed between CK levels, blood urea nitrogen (BUN), and the urea/creatinine ratio (UCR). The study also discusses potential pathophysiological mechanisms behind SARS-CoV-2's impact on skeletal muscles, emphasizing an indirect inflammatory response. Our findings underscore that while myositis in children with SARS-CoV-2 infection appears to follow a benign and self-limiting trajectory, it is crucial to monitor specific markers for early intervention and management. Further research is warranted to elucidate the underlying mechanisms and improve clinical outcomes.

Detection of Fungal Diseases in Lettuce by VIR-NIR Spectroscopy in Aquaponics

One of the main challenges facing the development of aquaponics is disease control, due on one hand to the fact that plants cannot be treated with chemicals because they can lead to mortality in cultured fish. The aim of this study was to apply the visible-near-infrared spectroscopy and vegetation index approach to test aquaponically cultivated lettuce (Lactuca sativa L.) infected with different fungal pathogens (Aspergillus niger, Fusarium oxysporum, and Alternaria alternata). The lettuces on the third leaf formation were placed in tanks (with dimensions 1 m/0.50 m/0.35 m) filled up with water from the aquaponics system every second day. In this study, we included reference fungal strains Aspergillus niger NBIMCC 3252, Fusarium oxysporum NBIMCC 125, and Alternaria alternata NBIMCC 109. Diffuse reflectance spectra of the leaves of lettuce were measured directly on the plants using a USB4000 spectrometer in the 450-1100 nm wavelength range. In near-infrared spectral range, the reflectance values of infected leaves are lower than those of the control, which indicates that some changes in cell structures occurred as a result of the fungal infection. All three investigated pathogens had a statistically significant effect on leaf water content and water band index. Vegetative indices such as Chlorophyll Absorption in Reflectance Index (CARI), Modified chlorophyll absorption in reflectance index (MCARI), Plant Senescence Reflectance Index (PSRI), Red Edge Index (REI2), Red Edge Index (REI3), and Water band index (WBI) were found to be effective in distinguishing infected plants from healthy ones, with WBI demonstrating the greatest reliability.

Pathophysiology, diagnosis, and management of neuroinflammation in covid-19

Although neurological complications of SARS-CoV-2 infection are relatively rare, their potential long term morbidity and mortality have a significant impact, given the large numbers of infected patients. Covid-19 is now in the differential diagnosis of a number of common neurological syndromes including encephalopathy, encephalitis, acute demyelinating encephalomyelitis, stroke, and Guillain-Barré syndrome. Physicians should be aware of the pathophysiology underlying these presentations to diagnose and treat patients rapidly and appropriately. Although good evidence has been found for neurovirulence, the neuroinvasive and neurotropic potential of SARS-CoV-2 is limited. The pathophysiology of most complications is immune mediated and vascular, or both. A significant proportion of patients have developed long covid, which can include neuropsychiatric presentations. The mechanisms of long covid remain unclear. The longer term consequences of infection with covid-19 on the brain, particularly in terms of neurodegeneration, will only become apparent with time and long term follow-up.

Kidney Injury in Critically Ill Patients with COVID-19 - From Pathophysiological Mechanisms to a Personalized Therapeutic Model

Acute kidney injury is a common complication of COVID-19, frequently fuelled by a complex interplay of factors. These include tubular injury and three primary drivers of cardiocirculatory instability: heart-lung interaction abnormalities, myocardial damage, and disturbances in fluid balance. Further complicating this dynamic, renal vulnerability to a "second-hit" injury, like a SARS-CoV-2 infection, is heightened by advanced age, chronic kidney disease, cardiovascular diseases, and diabetes mellitus. Moreover, the influence of chronic treatment protocols, which may constrain the compensatory intrarenal hemodynamic mechanisms, warrants equal consideration. COVID-19-associated acute kidney injury not only escalates mortality rates but also significantly affects long-term kidney function recovery, particularly in severe instances. Thus, the imperative lies in developing and applying therapeutic strategies capable of warding off acute kidney injury and decelerating the transition into chronic kidney disease after an acute event. This narrative review aims to proffer a flexible diagnostic and therapeutic strategy that recognizes the multi-faceted nature of COVID-19-associated acute kidney injury in critically ill patients and underlines the crucial role of a tailored, overarching hemodynamic and respiratory framework in managing this complex clinical condition.

Liver injury in patients with COVID-19 in comparison to patients with the pandemic influenza A (H1N1) 2009: a population-based study

BACKGROUND

Elevated liver tests in patients with COVID-19 are widely reported. Population-based studies utilizing a validated analysis of drug-induced liver injury (DILI), with a control group of other viral illnesses and follow-up are largely lacking.

MATERIALS AND METHODS

All hospitalized patients in Iceland with SARS-CoV-2 in 2020 and pandemic influenza A (H1N1) in 2009 were included in this retrospective, population-based study. Liver tests were compared between the two groups and the correlation to inflammatory markers and persistence of alanine aminotransferase (ALT) elevations were assessed. Potential DILI cases were reviewed using the Roussel Uclaf Causality Assessment Method (RUCAM).

RESULTS

225 SARS-CoV-2-positive and 73 influenza A (H1N1)-positive patients were included. Liver test values were similar between the groups, except for aspartate aminotransferase (AST) which was significantly lower in COVID-19, with a mean difference of 26 U/L (95%CI 4.2-47). Ferritin elevation was positively correlated with ALT, AST and alkaline phosphatase. No patient had persistently elevated ALT in COVID-19 and none had a probable DILI. Only 3 patients had a possible DILI according to the RUCAM.

CONCLUSIONS

Elevated liver enzymes are not specific for COVID-19. Hyperferritinemia was associated with elevated liver tests. DILI was very rare in COVID-19 and an unlikely cause of elevated liver enzymes in COVID-19. Abnormal liver tests are nonpersistent and generally not clinically important in these patients.

COVID-19-Triggered Acute Liver Failure and Rhabdomyolysis: A Case Report and Review of the Literature

COVID-19 is primarily known for its respiratory tract involvement, often leading to severe pneumonia and exacerbation of underlying diseases. However, emerging evidence suggests that COVID-19 can result in multiorgan failure, affecting organs beyond the respiratory system. We present the case of a 62-year-old male with COVID-19 who developed acute liver failure (ALF) and rhabdomyolysis in the absence of respiratory failure. Initially, the patient presented with significantly elevated aspartate transaminase (5398 U/L) and alanine transaminase (2197 U/L) levels. Furthermore, a prolonged prothrombin time international normalized ratio (INR) of 2.33 indicated the diagnosis of ALF without hepatic coma, according to Japanese diagnostic criteria. The patient also exhibited elevated creatine kinase (9498 U/L) and a mild increase in creatinine (1.25 mg/dL) levels, but both values improved with intravenous fluid support and molnupiravir administration. To our knowledge, this is the first reported case presenting with both ALF and rhabdomyolysis associated with COVID-19. In addition, we review the existing literature to summarize previously reported cases of ALF triggered by SARS-CoV-2. This case report underscores the significance of recognizing COVID-19 as a significant contributing factor in the development of multiorgan failure. Furthermore, it suggests that COVID-19 can lead to severe illness, irrespective of the absence of respiratory failure.

A severe case of rhabdomyolysis after Moderna mRNA anti-COVID-19 vaccine with a literature review

The identification of rhabdomyolysis as a potential fatal adverse reaction to recent COVID-19 vaccines is essential. As the symptoms of rhabdomyolysis are not specific, the threshold to actively search for this complication should be low.

Post-COVID Multisystem Inflammatory Syndrome-Adult (MIS-A) Presenting with Rhabdomyolysis and AKI

Multisystem inflammatory syndrome is a rarely reported post-COVID (coronavirus disease) phenomenon in adults. Our understanding of the multisystem inflammatory syndrome- adult (MIS-A) is based on multiple case reports that have demonstrated heterogeneous clinical presentations and treatment options. Rhabdomyolysis is an unusual presentation of MIS-A. We report the case of a 61-year-old man who presented with rhabdomyolysis with acute kidney injury (AKI), acute inflammatory demyelinating polyneuropathy (AIDP), myocarditis, disseminated intravascular coagulation, and minimal respiratory symptoms. The patient was found to have post-COVID inflammatory syndrome and recovered with supportive treatment and intravenous immunoglobulin (2 g/kg over 5 days). COVID-19 (coronavirus disease 2019) antibody positivity played a significant role in making the diagnosis of MIS-A and in providing prompt treatment.

Rhabdomyolysis after COVID-19 Infection: A Case Report and Review of the Literature

Rhabdomyolysis is a condition in which muscle breaks down potentially leading to renal dysfunction, and often occurs secondary to a precipitating factor. Viral or bacterial infections are common precipitants for initiating rhabdomyolysis. Recently, healthcare systems across the world have been challenged by a pandemic of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) causing ‘coronavirus disease 2019’ (COVID-19) disease. SARS-CoV-2 infection is recognized to cause respiratory and cardiovascular compromise, thromboembolic events, and acute kidney injury (AKI); however, it is not known whether it can precipitate rhabdomyolysis, with only a limited number of cases of SARS-CoV-2 infection preceding rhabdomyolysis reported to date. Here, we report the case of a 64-year-old woman who developed rhabdomyolysis shortly after SARS-CoV-2 infection and COVID-19. She initially presented with muscular pain, a creatine kinase level of 119,301 IU/L, and a mild rise in her creatinine level to 92 µmol/L, but successfully recovered with intravenous fluid support. We also review the literature to summarise previously reported cases of rhabdomyolysis precipitated by SARS-CoV-2, highlighting the need to consider this diagnosis in patients presenting with SARS-CoV-2 and myalgia.

Successful Treatment of Delayed Localized Necrotizing Inflammatory Myositis After Severe Acute Respiratory Syndrome Coronavirus 2 mRNA-1273 Vaccine: A Case Report

Reported adverse reactions to the mRNA-1273 vaccine (Spikevax, Moderna Inc) against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) range from mild, local delayed cutaneous reactions to rarer, more serious reactions such as myocarditis. Here, we describe the presentation and successful treatment of delayed, localized necrotizing inflammatory myositis following a third dose of the mRNA-1273 SARS-CoV-2 vaccine. To our knowledge, this is the first report of biopsy-confirmed, delayed inflammatory myositis after administration of an mRNA-1273 SARS-CoV-2 vaccine booster.

Rhabdomyolysis in Pediatric Patients with SARS-CoV-2 Infection

Background: Rhabdomyolysis is a rare but severe complication in adult patients with Coronavirus disease 2019 (COVID-19), which can result in acute kidney injury and death; however, it is rarely reported in pediatric patients. Methods: In this study, we retrospectively reviewed the clinical features and outcomes of rhabdomyolysis in pediatric patients aged 0–18 years with COVID-19 who were hospitalized at Taipei Tzu Chi Hospital, an epicenter of COVID-19 in northern Taiwan. Results: We treated eight patients with rhabdomyolysis during the omicron variant-Severe acute respiratory syndrome coronavirus 2 (omicron variant-SARS-CoV-2) community outbreak and none during the alpha variant endemic. These eight patients shared stereotypical presentations, including the presence of bilateral calf pain after defervescence. The creatinine kinase (CK) levels were between 1346 and 6937 U/L on admission, and clinical course was uneventful after aggressive saline hydration. Conclusion: Rhabdomyolysis is not a rare complication in pediatric patients with the omicron-SARS-CoV-2 infection, and reassurance of a good prognosis is important to alleviate family anxiety.

Prognostic Value of Routine Blood Parameters in Intensive Care Unit COVID-19 Patients

INTRODUCTION

Laboratory medicine has an important role in the management of COVID-19. The aim of this study was to analyze routinely available blood parameters in intensive care unit COVID-19 patients and to evaluate their prognostic value.

PATIENTS AND METHODS

This is a retrospective, observational, single-center study including consecutive severe COVID-19 patients who were admitted into the intensive care unit of Ben Arous Regional Hospital in Tunisia from 28 September 2020 to 31 May 2021. The end point of the study was either hospital discharge or in-hospital death. We defined two groups based on the outcome: survivors (Group 1) and non-survivors (Group 2). Demographical, clinical, and laboratory data on admission were collected and compared between the two groups. Univariate and multivariate logistic regression analysis were performed to determine the predictive factors for COVID-19 disease mortality.

RESULTS

A total of 150 patients were enrolled. Eighty patients (53.3%) died and 70 (46.7%) survived during the study period. Based on statistical analysis, median age, Simplified Acute Physiology Score (SAPS II) with the serum levels of urea, creatinine, total lactate dehydrogenase (LDH), creatine kinase, procalcitonin and hs-troponin I were significantly higher in non-survivors compared to survivors. On multivariate analysis, LDH activity ≥ 484 U/L (OR=17.979; 95%CI [1.119-2.040]; p = 0.09) and hs-troponin I ≥ 6.55 ng/L (OR=12.492; 95%CI [1.691-92.268]; p = 0.013) independently predicted COVID-19 related mortality.

CONCLUSION

Total LDH and hs-troponin I were independent predictors of death. However, further clinical investigations with even larger number of patients are needed for the evaluation of other laboratory biomarkers which could aid in assessing the prediction of mortality.

Systematic Review on Pathophysiological Complications in Severe COVID-19 among the Non-Vaccinated and Vaccinated Population

COVID-19, caused by SARS-CoV-2, is one of the longest viral pandemics in the history of mankind, which have caused millions of deaths globally and induced severe deformities in the survivals. For instance, fibrosis and cavities in the infected lungs of COVID-19 are some of the complications observed in infected patients post COVID-19 recovery. These health abnormalities, including is multiple organ failure-the most striking pathological features of COVID-19-have been linked with diverse distribution of ACE2 receptor. Additionally, several health complications reports were reported after administration of COVID-19 vaccines in healthy individuals, but clinical or molecular pathways causing such complications are not yet studied in detail. Thus, the present systematic review established the comparison of health complication noted in vaccinated and non-vaccinated individuals (COVID-19 infected patients) to identify the association between vaccination and the multiorgan failure based on the data obtained from case studies, research articles, clinical trials/Cohort based studies and review articles published between 2020-2022. This review also includes the biological rationale behind the COVID-19 infection and its subsequent symptoms and effects including multiorgan failure. In addition, multisystem inflammatory syndrome (MIS) has been informed in individuals post vaccination that resulted in multiorgan failure but, no direct correlation of vaccination with MIS has been established. Similarly, hemophagocytic lymphohistiocytosis (HLH) also noted to cause multiorgan failure in some individuals following full vaccination. Furthermore, severe complications were recorded in elderly patients (+40 years of age), indicates that older age individuals are higher risk by COVID-19 and post vaccination, but available literature is not sufficient to comply with any conclusive statements on relationship between vaccination and multiorgan failure.

Rhabdomyolyse au cours de l’infection par COVID-19

Introduction

La COVID-19 est une maladie systémique qui se présente avec une pléthore de manifestations dont la fièvre, la toux et les maux de gorge qui ont été les symptômes les plus rapportés associés à la maladie. Il apparaît désormais que l’appareil locomoteur n’est pas non plus épargné avec des manifestations musculo-squelettiques allant d’une légère élévation de la créatine kinase (CPK) avec une faiblesse légère ou nulle à une rhabdomyolyse sévère.

Observation

Nous rapportons l’observation d’une patiente âgée de 26 ans atteinte d’une infection à Sars-Cov-2 compliquée d’une rhabdomyolyse. La patiente a présenté un syndrome fébrile avec une pharyngite justifiant la réalisation d’un test antigénique Covid-19 revenu négatif. Une semaine plus tard, alors que ses symptômes s’améliorent, elle rapporte des myalgies des quatre membres avec une faiblesse motrice prédominant à la ceinture scapulaire d’aggravation progressive. La patiente est admise au SAU. Ses antécédents sont marqués par une dermatite atopique et une rhinite allergique. Elle est vaccinée (2 doses) contre le Sars-Cov-2 depuis plus de 6 mois. L’examen neurologique objectif un déficit coté à 4/5 aux membres inférieurs et 3/5 aux membres supérieurs, sans déficit sensitif et sans anomalies des réflexes. Elle ne présente pas d’exanthème ni d’arthralgies, ni de dysphagie. Le bilan montre un taux de CPK à 22 502 UI/L, un ionogramme normal, une cytolyse hépatique ASAT à 599 UI/L et ALAT à 730 UI/L, une CRP à 3 mg/L, une VS à 13 mm, une hyperleucocytose à 11 900/μL, une lymphopénie à 700/μL. La bandelette urinaire est en faveur d’une myoglobinurie. Le sédiment urinaire est normal. L’ECG est sans anomalies. La patiente est mise sous prednisone à 60 mg/j et hyperhydratation. L’aggravation de la créatinine sérique passant de 5 mg/L à 22 mg/L fait démarrer en urgence un bolus de 1 g de méthylprednisolone pendant 03 jours avec relai par la prednisone à 60 mg/j. Les anticorps anti-nucléaires sont négatifs. La sérologie COVID-19 réalisée montre les IgM anti Sars-Cov-2 à 96,73 U/L et les IgG négatives signant une infection récente. L’évolution est favorable en 15 jours avec disparition du déficit moteur, de la cytolyse et normalisation des CPK permettant d’entamer la dégression des corticoïdes et leur arrêt.

Discussion

En juillet 2020, une première observation de myosite liée au Sars-Cov-2 a été rapportée dans la littérature. Depuis, près de 23 patients ont présenté une myosite attribuable au COVID-19[1]. L’atteinte musculaire peut varier d’une élévation asymptomatique de la CK à une rhabdomyolyse sévère [2].

Le SARS-CoV-2 a été isolé de plusieurs organes et soulève la possibilité que le virus infecte les muscles striés et entraîne potentiellement une dégradation musculaire. Une autre hypothèse est que les lésions musculaires squelettiques pourraient être causées par la réponse immunitaire de type « tempête de cytokines » de l’hôte [3]

Conclusion

L’infection par le SRAS-CoV-2 présente un large éventail de manifestations cliniques secondaires à l’atteinte de différents organes. Le spectre des dommages du COVID-19 est toujours un sujet en évolution, et des recherches supplémentaires sont nécessaires pour révéler les mécanismes exacts par lesquels le SRAS-CoV-2 conduit à la rhabdomyolyse qui reste une manifestation clinique atypique. Étant donné que les myalgies peuvent être un symptôme précoce de la rhabdomyolyse, celle-ci doit être suspectée chez les patients qui présentent des myalgies sévères. Les cliniciens doivent être conscients de cette présentation rare de la COVID-19.

COVID-19 associated rhabdomyolysis leading to major amputation in the absence of macrovascular thrombosis

A 50 year old patient presented with bilateral lower extremity weakness, lethargy, and dyspnea. Nasopharyngeal swab was positive for SARS-CoV-2. She progressed to acute hypoxemic respiratory failure and hemodynamic instability requiring intubation, pressor support, and hemodialysis. Maculopapular rashes developed on bilateral lower extremities with progressively worsening rhabdomyolysis. Bilateral lower extremity fasciotomies were performed with subsequent serial operative debridements to remove necrotic muscle. One month later, she required a right above knee amputation. There was no evidence of macrovascular thrombosis. A high clinical suspicion of rhabdomyolysis in COVID-19 patients is necessary to avoid major limb loss.

Clinicopathological Characteristics of Inflammatory Myositis Induced by COVID-19 Vaccine (Pfizer-BioNTech BNT162b2): A Case Report

As more individuals were coronavirus disease 2019 (COVID-19) vaccinated, unexpected side effects appeared. Herein, we present the case of a 30-year-old man with myopathy in both extremities after the second dose of the Pfizer-BioNTech (BNT162b2) COVID-19 vaccine. Symptoms, swelling and pain, started from the proximal upper and lower extremities and extended to the distal parts. Although he underwent massive hydration, the muscle enzyme level continuously increased. He complained of dysphagia and dysarthria. Microscopically, muscle biopsy showed multifocal or scattered macrophage infiltration and degenerated myofibers. In contrast to general myopathy including inflammatory myositis and rhabdomyolysis, vaccine-induced inflammatory myositis shows a prolonged increase in muscle enzyme levels and multifocal macrophage infiltration with necrosis of the muscle fibers. Symptoms improved with glucocorticoid and immunosuppressive treatment. If vaccinated individuals experience severe and continuous muscle pain and swelling, clinicians should consider vaccine-induced inflammatory myositis, measure the muscle enzyme levels, and perform muscle biopsy for a definite diagnosis.

The Musculoskeletal Involvement After Mild to Moderate COVID-19 Infection

COVID-19, a disease caused by the novel coronavirus SARS-CoV-2, has been drastically affecting the daily lives of millions of people. COVID-19 is described as a multiorgan disease that affects not only the respiratory tract of infected individuals, but it has considerable effects on the musculoskeletal system, causing excessive fatigue, myalgia, arthralgia, muscle weakness and skeletal muscle damage. These symptoms can persist for months, decreasing the quality of life of numerous individuals. Curiously, most studies in the scientific literature focus on patients who were hospitalized due to SARS-CoV-2 infection and little is known about the mechanism of action of COVID-19 on skeletal muscles, especially of individuals who had the mild to moderate forms of the disease (non-hospitalized patients). In this review, we focus on the current knowledge about the musculoskeletal system in COVID-19, highlighting the lack of researches investigating the mild to moderate cases of infection and pointing out why it is essential to care for these patients. Also, we will comment about the need of more experimental data to assess the musculoskeletal manifestations on COVID-19-positive individuals.

Case Report: Severe Rhabdomyolysis and Multiorgan Failure After ChAdOx1 nCoV-19 Vaccination

Background

Severe skeletal muscle damage has been recently reported in patients with SARS-CoV-2 infection and as a rare vaccination complication.

Case summary

On Apr 28, 2021 a 68-year-old man who was previously healthy presented with an extremely severe rhabdomyolysis that occurred nine days following the first dose of SARS-CoV-2 ChAdOx1 nCov-19 vaccination. He had no risk factors, and denied any further assumption of drugs except for fermented red rice, and berberine supplement. The clinical scenario was complicated by a multi organ failure involving bone marrow, liver, lung, and kidney. For the rapid increase of the inflammatory markers, a cytokine storm was suspected and multi-target biologic immunosuppressive therapy was started, consisting of steroids, anakinra, and eculizumab, which was initially successful resulting in close to normal values of creatine phosphokinase after 17 days of treatment. Unfortunately, 48 days after the vaccination an accelerated phase of deterioration, characterized by severe multi-lineage cytopenia, untreatable hypotensive shock, hypoglycemia, and dramatic increase of procalcitonin (PCT), led to patient death.

Conclusion

Physicians should be aware that severe and fatal rhabdomyolysis may occur after SARS-CoV2 vaccine administration.

Concurrent myopathy and inflammatory cardiac disease in COVID-19 patients: a case series and literature review

Adult COVID-19 patients can present with acute muscle and/or cardiac involvement. Our study aims to describe the incidence and characteristics of patients with the co-occurrence of COVID-19 myopathy and inflammatory cardiac disease. We retrospectively reviewed all COVID-19 patients admitted to a large tertiary center to assess the co-occurrence of myopathy and inflammatory cardiac disease. We conducted a literature review of prior relevant case reports. There were three COVID-19 patients with concurrent involvement from our center and five cases in the published literature. Overall, mean age was 57.7 ± 16, four were females (50%) and only two patients (25%) had major relevant comorbidities. Muscle involvement included rhabdomyolysis or myositis and cardiac involvement included myocarditis or pericarditis. Most patients (75%) had no respiratory COVID-19 symptoms. Troponin and creatine phosphokinase levels were higher than twofold of the upper limit of normal for all patients. Steroids were used in the treatment of most patients (75%). All patients had a resolution or improvement of their extra-pulmonary involvement while two (25%) deteriorated due to COVID-19 pneumonia. The incidence for this co-occurrence is 0.07% among hospitalized COVID-19 patients. Patients with these rare COVID-19 simultaneous manifestations have distinct features. They are generally younger, present with extra-pulmonary symptoms and do not have severe respiratory compromise. An underdiagnosis causing treatment delay is possible. Further study is needed.

Evaluation of the effectiveness of the Nutritional Risk Screening System 2002 (NRS-2002) in COVID-19 patients admitted to the intensive care unit

BACKGROUND

Nutritional status of patients with COVID-19 can affect the recovery process of patients; however, no nutritional scale was introduced to evaluate the nutritional status of the patients. Thus, the main objective of this study was to examine the usefulness of Nutritional status-2002 (NRS-2002) among COVID-19 patients admitted to the intensive care unit (ICU).

MATERIAL AND METHODS

In this cross-sectional study, 73 patients with definitive corona diagnosis admitted to the ICUs of Al-Zahra hospital, Isfahan, Iran in October 2020 to January 2021 were recruited. Dietary intake, NRS-2002, demographic, anthropometric and biochemical indices of patients were recorded.

RESULTS

The majority of patients were at risk for moderate (69.9%) to severe (12.3%) malnutrition. Daily calorie intake (P = .001) and albumin (P = .001) levels in deceased patients were significantly lower than the recovered group. A direct correlation between NRS-2002 and age (P < .001) and an inverse correlation with daily calorie intake (P = .002), albumin (P = .05) and PaO2 (P = .034) was found. Moreover, there is a strong correlation between NRS-2002 score and chance of death among COVID-19 patients (OR=34.5, 95%CI:(5.2 - 228.93), P-value<0.001). Likewise, the levels of bilirubin direct (OR=8, 95%CI:(1.30 - 49.38), P-value=0.025) and creatine-phosphokinase (OR=0.9, 95%CI:(0.99 - 1.00), P-value=0.035) have a significant direct association with chance of death.

CONCLUSION

Results showed patients with COVID-19 admitted to the ICU did not have appropriate nutritional status and mortality was higher among patients with lower amounts of the serum albumin and daily calorie intakes. Furthermore, there is a strong association between the NRS-2002 index and the chance of mortality in these patients.

Incidence, Risk Factors, and Outcomes of Rhabdomyolysis in Hospitalized Patients With COVID-19 Infection

INTRODUCTION

There is a paucity of studies examining the prevalence and clinical characteristics of rhabdomyolysis in hospitalized patients with COVID-19 infection. The purpose of this study is to examine the incidence, clinical characteristics, and outcome of hospitalized patients with COVID-19 infection who develop rhabdomyolysis.

METHODOLOGY

This is a single-center retrospective analysis of all hospitalized patients with COVID-19 admitted between March 8, 2020, and January 11, 2021. All patients with creatinine kinase (CK) levels available during the hospital admission were included. Rhabdomyolysis was defined as an elevation in CK level higher than five times the upper limit of normal (i.e., 1125 U/L). We compared clinical characteristics and outcomes of patients who developed rhabdomyolysis with patients who did not develop rhabdomyolysis.

RESULTS

The incidence of rhabdomyolysis in hospitalized patients with COVID-19 infection was 9.2%. There was no significant difference noted in comorbidities and clinical characteristics between the two groups. Moreover, there was no significant difference noted in the presence of severe COVID-19 infection (72.7% vs 54.6%, p = 0.1), mortality (27.3% vs 23.9%, p = 0.72), acute kidney injury (59.1% vs 42.7%, p = 0.14), or need for intensive care unit (ICU) care (72.7% vs 51.4%, p = 0.051). However, a higher percentage of patients in the rhabdomyolysis group required physical rehabilitation after discharge (40.9% vs 19.3%, p = 0.02).

CONCLUSION

The overall incidence of rhabdomyolysis in hospitalized patients with COVID-19 infection was high (9.2%). The presence of rhabdomyolysis was not associated with the increased severity of the disease. Patients with rhabdomyolysis more frequently required physical rehabilitation compared to those without rhabdomyolysis.

Severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) /Hepatitis B virus (HBV) Co-infected Patients: A case series and review of the literature

OBJECTIVE

We aimed to determine whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)/hepatitis B virus (HBV) coinfection affects liver function and the outcome of the disease.

METHODS

One hundred fifty-six laboratories confirmed SARS-CoV-2 positive patients were followed up between 1 July and 31 December 2020 and analysed retrospectively. Continuous variables were compared with the independent samples t-test. Categorical variables were compared using the Pearson's chi-square or Fisher's exact test. A P value of less than .05 was considered statistically significant.

RESULTS

The age range of the cohort was from 40 to 78 and 73 (46.8%) of 156 patients were male. There was no significant difference in age and gender distribution between 20 patients (12.8%) with SARS-CoV-2/HBV coinfection and 136 patients without HBV infection (87.2%) (P > .05). Liver function tests were higher in the SARS-CoV-2/HBV coinfected patient group but were not statistically significant. The levels of creatine kinase (CK) were significantly higher in coronavirus disease 2019 (COVID-19) patients without HBV infection compared with the SARS-CoV-2/HBV coinfected patient group (P = .0047). Severe/critical illness was less common in the SARS-CoV-2/HBV coinfected patient group, and no deaths were observed.

CONCLUSIONS

SARS-CoV-2/HBV coinfection did not change the severity and outcome of COVID-19. However, the patients with SARS-CoV-2/HBV coinfection should be closely monitored for liver complications.

Myoglobin Offers Higher Accuracy Than Other Cardiac-Specific Biomarkers for the Prognosis of COVID-19

Although sporadic studies have shown that myoglobin may have better prognostic performance than other cardiac markers in COVID-19, a comprehensive comparative study is lacking. Herein, we retrospectively analyzed the clinical and laboratory data of COVID-19 patients admitted to the Guanggu Campus of Wuhan Tongji Hospital from February 9, 2020 to March 30, 2020, intending to compare the prognostic accuracy of three commonly used cardiac markers on COVID-19 mortality. Our results revealed that abnormal increases in myocardial biomarkers were associated with a significantly increased risk of in-hospital mortality with COVID-19. Interestingly, myoglobin, a non-cardiac-specific biomarker, also expressed in skeletal myocytes, had even higher prognostic accuracy than cardiac-specific biomarkers such as high-sensitivity troponin I (hs-TnI) and creatine kinase-MB (CK-MB). More importantly, multivariate Cox analysis showed that myoglobin, rather than hs-TnI or CK-MB, was independently prognostic for in-hospital mortality in COVID-19. These results were further confirmed by subgroup analyses of patients with severe and critical illnesses and those without a history of cardiovascular disease. Our findings suggest that myoglobin may be a reliable marker of illness reflecting general physiological disturbance and help to assess prognosis and treatment response in patients with COVID-19.

Neurological Presentations of COVID-19: Characteristic Features in a Case Series of Hospitalized Patients from Abu Dhabi, UAE

Background

COVID-19 patients can present with neurological manifestations in the form of headache, dizziness, hyposmia, myalgia, peripheral neuropathy, acute cerebrovascular disease, and encephalopathy. Neurological involvement could be due to virus-induced brain hypoxia, brain infection, or immune reaction. We aim to describe the neurological presentation of COVID-19 patients and study their neuroimaging findings and disease outcome.

Method

The study is a single-centre, retrospective, observational study in Sheikh Shakhbout Medical City (SSMC), Abu Dhabi, UAE. Patients diagnosed with COVID-19 between March and May 2020 who presented with neuropathological features with or without respiratory manifestations of COVID-19 were enrolled. Electronic records were studied for age, sex, duration of hospitalization, detailed neurological presentation, history or documented concomitant fever and respiratory features of COVID-19, inflammatory markers, neuroimaging, progress, and disease outcome.

Results

Thirty-three patients of 10 nationalities presented with neurological manifestations. Mean (range) age was 51.4 (21–86) years. Twenty-four had comorbidities, and 18 had no prior or concomitant respiratory symptoms. Ten patients presented with encephalopathy and exhibited altered behavior/sensorium: 7 presented with myositis, 8 with stroke, and 4 with seizures, and 4 had peripheral and cranial nerve involvement. The mean (average) duration of hospital stay was 11.4 days (1-38) with the longest observed in stroke patients. Fifteen patients (45%) died and 3 (9%) had residual weakness. Serum ferritin, CRP, and procalcitonin were higher in the severe disease group and correlated with risk of death. Twelve of 22 brain images showed abnormalities including haemorrhage, infarcts, small vessel ischemia, and oedema. Risk of death was higher in older age but did not differ based on the underlying neuropathology.

Conclusion

COVID-19 patients who present with neurological involvement have a higher risk of mortality which is aggravated by older age and higher inflammatory markers. The type of neurological pathology does not seem to influence the risk of mortality.

COVID-19 and Myositis: What We Know So Far

PURPOSE

Myositis as a rare manifestation of COVID-19 is only recently being reported. This review examines the current literature on COVID-19-induced myositis focusing on etiopathogenesis, clinical presentations, diagnostic practices, and therapeutic challenges with immunosuppression, and the difficulties experienced by rheumatologists in established myositis in the COVID-19 era.

RECENT FINDINGS

COVID-19 is associated with a viral myositis attributable to direct myocyte invasion or induction of autoimmunity. COVID-19-induced myositis may be varied in presentation, from typical dermatomyositis to rhabdomyolysis, and a paraspinal affliction with back pain. It may or may not present with acute exponential elevations of enzyme markers such as creatine kinase (CK). Virus-mediated muscle inflammation is attributed to ACE2 (angiotensin-converting enzyme) receptor-mediated direct entry and affliction of muscle fibers, leading on to innate and adaptive immune activation. A greater recognition of the stark similarity between anti-MDA5-positive myositis with COVID-19 has thrown researchers into the alley of exploration - finding common etiopathogenic basis as well as therapeutic strategies. For patients with established myositis, chronic care was disrupted during the pandemic with several logistic challenges and treatment dilemmas leading to high flare rates. Teleconsultation bridged the gap while ushering in an era of patient-led care with the digital transition to tools of remote disease assessment. COVID-19 has brought along greater insight into unique manifestations of COVID-19-related myositis, ranging from direct virus-induced muscle disease to triggered autoimmunity and other etiopathogenic links to explore. A remarkable shift in the means of delivering chronic care has led patients and caregivers worldwide to embrace a virtual shift with teleconsultation and opened doorways to a new era of patient-led care.

Rhabdomyolysis Following Recovery from Severe COVID-19: A Case Report

BACKGROUND Rhabdomyolysis occurs when muscle injury leads to the release of muscle cell constituents into circulation, often leading to significant systemic complications. There are many causes of rhabdomyolysis, and the etiology is often multifactorial or unclear. Current data suggest that acute COVID-19 may cause muscle injury that can lead to rhabdomyolysis, particularly in cases of severe illness requiring prolonged hospitalization; however, data on the long-term effects of COVID-19 on the musculoskeletal system are lacking. CASE REPORT We present a case of a woman with generalized weakness 1 week following discharge from the hospital after a prolonged admission for severe COVID-19. She was found to have acute kidney injury and elevated creatine kinase (CK) of 1775 U/L (normal 36-234 U/L). Her home medications, including her statin, were held, but her CK continued to rise, peaking at 15 085 U/L, and she developed renal failure necessitating renal replacement therapy. A thorough work-up for the underlying etiology of her rhabdomyolysis was pursued, including testing for autoimmune myositis, statin-associated necrotizing autoimmune myositis, and a muscle biopsy, which were all unrevealing. Ultimately, the patient's rhabdomyolysis was determined to likely be secondary to a post-viral myopathy from COVID-19. A toxic myopathy from medication use or a delayed critical illness myopathy from her recent prolonged hospitalization could have also contributed. CONCLUSIONS This case highlights the wide differential diagnosis of rhabdomyolysis in the setting of recent COVID-19 and prolonged hospitalization. It demonstrates the possibility that muscle injury and resultant rhabdomyolysis may be a late complication of COVID-19 that is not yet fully described in the literature.

Increased Creatine Kinase May Predict A Worse COVID-19 Outcome

Early reports from Asia suggested that increased serum levels of the muscular enzyme creatine-(phospho)-kinase (CK/CPK) could be associated with a more severe prognosis in COVID-19. The aim of this single-center retrospective cohort study of 331 consecutive COVID-19 patients who were hospitalized during Italy’s “first wave” was to verify this relationship, and to evaluate the role of possible confounding factors (age, body mass index, gender, and comorbidities). We subdivided our cohort in two groups, based on “severe” (n = 99) or “mild” (n = 232) outcomes. “Severe” disease is defined here as death and/or mechanical invasive ventilation, in contrast to “mild” patients, who were discharged alive with no need for invasive ventilation; this latter group could also include those patients who were treated with non-invasive ventilation. The CK levels at admission were higher in those subjects who later experienced more severe outcomes (median, 126; range, 10–1672 U/L, versus median, 82; range, 12–1499 U/L, p = 0.01), and hyperCKemia >200 U/L was associated with a worse prognosis. Regression analysis confirmed that increased CK acted as an independent predictor for a “severe” outcome. HyperCKemia was generally transient, returning to normal during hospitalization in the majority of both “severe” and “mild” patients. Although the direct infection of voluntary muscle is unproven, transient muscular dysfunction is common during the course of COVID-19. The influence of this novel coronavirus on voluntary muscle really needs to be clarified.

Rhabdomyolysis in Severe COVID-19: Male Sex, High Body Mass Index, and Prone Positioning Confer High Risk

BACKGROUND

Bedside experience and studies of critically ill patients with coronavirus disease 2019 (COVID-19) indicate COVID-19 to be a devastating multisystem disease. We aim to describe the incidence, associated variables, and outcomes of rhabdomyolysis in critically ill COVID-19 patients.

MATERIALS AND METHODS

Data for all critically ill adult patients (≥18 years old) admitted to the ICU at a large academic medical center with confirmed COVID-19 between March 13, 2020 and April 18, 2020 were prospectively collected. Patients with serum creatine kinase (CK) concentrations greater than 1000 U/L were diagnosed with rhabdomyolysis. Patients were further stratified as having moderate (serum CK concentration 1000-4999 U/L) or severe (serum CK concentration ≥5000 U/L) rhabdomyolysis. Univariate and multivariate analyses were performed to identify outcomes and variables associated with the development of rhabdomyolysis.

RESULTS

Of 235 critically ill COVID-19 patients, 114 (48.5%) met diagnostic criteria for rhabdomyolysis. Patients with rhabdomyolysis more often required mechanical ventilation (P < 0.001), prone positioning (P < 0.001), pharmacological paralysis (P < 0.001), renal replacement therapy (P = 0.010), and extracorporeal membrane oxygenation (ECMO) (P = 0.025). They also had longer median ICU length of stay (LOS) (P < 0.001) and hospital LOS (P < 0.001). No difference in mortality was observed. Male sex, patients with morbid obesity, SOFA score, and prone positioning were independently associated with rhabdomyolysis.

CONCLUSIONS

Nearly half of critically ill COVID-19 patients in our cohort met diagnostic criteria for rhabdomyolysis. Male sex, morbid obesity, SOFA score, and prone position were independently associated with rhabdomyolysis.

COVID-19 infection and severe rhabdomyolysis

Although patients with COVID-19 can have mild nonspecific myalgia and mild elevation of creatinine kinase levels, severe myalgia along with elevation of creatinine kinase levels >10 times the upper normal limit and dark-colored urine indicate an underlying severe rhabdomyolysis. This report describes a 60-year-old morbidly obese man who was found to have severe rhabdomyolysis, along with acute kidney injury, dark-colored urine, and a positive COVID-19 test. He had a prolonged hospital course requiring continuous renal replacement therapy, mechanical ventilation, and multiple vasopressors and eventually died of multiorgan failure. The management of severe rhabdomyolysis and COVID-19 is challenging, and fluid resuscitation should be done cautiously, monitoring for early signs of fluid overload.

The prognostic value of elevated creatine kinase to predict poor outcome in patients with COVID-19 - A systematic review and meta-analysis

BACKGROUND AND AIMS

Creatine kinase (CK), a marker of muscle damage, is potentially associated with a more severe COVID-19. In this systematic review and meta-analysis, we aim to evaluate the association between the elevated CK and severity and mortality in COVID-19.

METHODS

We performed a systematic literature search on PubMed, Scopus, and Embase up until January 26, 2020. The main outcome was poor outcome, a composite of mortality and severe COVID-19.

RESULTS

There are 2471 patients from 14 studies included in this systematic review and meta-analysis. The incidence of elevated CK in this pooled analysis was 17% (11%, 22%) and the incidence of poor outcome in this pooled analysis was 27% (19%, 34%). Elevated CK was associated with poor outcome in patients with COVID-19 (OR 3.01 [2.21, 4.10], p < 0.001; I²: 10.2%). The effect estimate did not vary with age (p = 0.610), male (p = 0.449), hypertension (p = 0.490), and diabetes (p = 0.457). Elevated CK has a sensitivity of 0.24 (0.17, 0.32), specificity of 0.91 (0.86, 0.94), PLR of 2.6 (1.9, 3.7), NLR of 0.84 (0.78, 0.90), DOR of 3 (2, 5), and AUC of 0.62 (0.57, 0.66) for predicting poor outcome in patients with COVID-19. In this pooled analysis, elevated CK confers to a 49% probability for poor outcome and a non-elevated CK confers to a 24% probability. Subgroup analysis and univariate meta-regression indicates that the sensitivity and specificity does not vary with age, male, hypertension, and diabetes.

CONCLUSION

Elevated CK was associated with increased mortality and severity in patients with COVID-19.

Ratios between circulating myeloid cells and lymphocytes are associated with mortality in severe COVID-19 patients

Recent studies indicate that host immune responses are dysregulated with either myeloid cell compartment or lymphocyte composition being disturbed in COVID-19. This study aimed to assess the impact of SARS-CoV-2 viral infection on the composition of circulating immune cells in severe COVID-19 patients. In this retrospective single-center cohort, 71 out of 87 COVID-19 patients admitted to the intense care unit for oxygen treatment were included in this study. Demographics, clinical features, comorbidities, and laboratory findings were collected on admission. Out of the 71 patients, 5 died from COVID-19. Compared with survived patients, deceased patients showed higher blood cell counts of neutrophils and monocytes but lower cell counts of lymphocytes. Intriguingly, the neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), and basophil-to-lymphocyte ratio (BLR) were markedly higher in deceased patients compared to survived patients. Furthermore, the lymphocyte counts were negatively correlated with D-dimer levels, while the ratios between myeloid cells and lymphocyte (NLR, MLR, and BLR) were positively correlated with D-dimer levels. Our findings revealed that the ratios between myeloid cells and lymphocytes were highly correlated with coagulation status and patient mortality in severe COVID-19.

Clinical, electromyographical, histopathological characteristics of COVID-19 related rhabdomyolysis

Rhabdomyolysis is an uncommon complication of the coronavirus disease 2019 (COVID-19) infection. Previous reports have described its management and treatment in medical units, but have not discussed confirmatory tests or differential diagnosis. We report a case of a 58 year-old male patient, who was admitted for COVID-19 pneumonia and subsequently developed severe weakness, inability to move limbs, acute renal failure, significantly elevated myoglobin and creatinine kinase, and was diagnosed with rhabdomyolysis. Continuous renal replacement therapy, the treatment modality of choice over hyperhydration due to ongoing mechanical ventilation, was effective in resolving symptoms. No direct viral invasion of muscles was noted on biopsy. Here, we describe his symptoms, electromyography, and muscular biopsy results, and further discuss the possible differential diagnoses. Neuromuscular symptoms related to COVID-19 require careful clinical analysis. In addition, detailed reports of patients' course of illness and diagnoses will assist in improving care for affected patients.

The emerging spectrum of COVID-19 neurology: clinical, radiological and laboratory findings

Preliminary clinical data indicate that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is associated with neurological and neuropsychiatric illness. Responding to this, a weekly virtual coronavirus disease 19 (COVID-19) neurology multi-disciplinary meeting was established at the National Hospital, Queen Square, in early March 2020 in order to discuss and begin to understand neurological presentations in patients with suspected COVID-19-related neurological disorders. Detailed clinical and paraclinical data were collected from cases where the diagnosis of COVID-19 was confirmed through RNA PCR, or where the diagnosis was probable/possible according to World Health Organization criteria. Of 43 patients, 29 were SARS-CoV-2 PCR positive and definite, eight probable and six possible. Five major categories emerged: (i) encephalopathies (n = 10) with delirium/psychosis and no distinct MRI or CSF abnormalities, and with 9/10 making a full or partial recovery with supportive care only; (ii) inflammatory CNS syndromes (n = 12) including encephalitis (n = 2, para- or post-infectious), acute disseminated encephalomyelitis (n = 9), with haemorrhage in five, necrosis in one, and myelitis in two, and isolated myelitis (n = 1). Of these, 10 were treated with corticosteroids, and three of these patients also received intravenous immunoglobulin; one made a full recovery, 10 of 12 made a partial recovery, and one patient died; (iii) ischaemic strokes (n = 8) associated with a pro-thrombotic state (four with pulmonary thromboembolism), one of whom died; (iv) peripheral neurological disorders (n = 8), seven with Guillain-Barré syndrome, one with brachial plexopathy, six of eight making a partial and ongoing recovery; and (v) five patients with miscellaneous central disorders who did not fit these categories. SARS-CoV-2 infection is associated with a wide spectrum of neurological syndromes affecting the whole neuraxis, including the cerebral vasculature and, in some cases, responding to immunotherapies. The high incidence of acute disseminated encephalomyelitis, particularly with haemorrhagic change, is striking. This complication was not related to the severity of the respiratory COVID-19 disease. Early recognition, investigation and management of COVID-19-related neurological disease is challenging. Further clinical, neuroradiological, biomarker and neuropathological studies are essential to determine the underlying pathobiological mechanisms that will guide treatment. Longitudinal follow-up studies will be necessary to ascertain the long-term neurological and neuropsychological consequences of this pandemic.
