Critical illness neuropathy

OBJECTIVES: To report a case-control study of new-onset small fiber neuropathy (SFN) after COVID-19 with invasive cardiopulmonary exercise testing (iCPET). SFN is a critical objective finding in long COVID and amenable to treatment. METHODS: A retrospective chart review was conducted on patients seen in the NeuroCOVID Clinic at Yale who developed new-onset SFN after a documented COVID-19 illness. We collected demographics, symptoms, skin biopsy, iCPET testing, treatments, and clinical response to treatment or no intervention...

Light chain amyloidosis is a plasma-cell disorder with a poor prognosis. It is a progressive condition, causing worsening pain, disability, and life-limiting complications involving multiple organ systems. The medical regimen can be complex, including chemotherapy or immunotherapy for the disease itself, as well as treatment for pain, gastrointestinal and cardiorespiratory symptoms, and various secondary symptoms. Patients and their families must have a realistic awareness of the illness and of the goals and limitations of treatments in making informed decisions about medical therapy, supportive management, and end-of-life planning...

Dysphagia is a common manifestation of endocrine and metabolic diseases. Swallowing is a complex neuromuscular process, with an interplay of sensory and motor function, that has voluntary and involuntary control. Disruptions in any of these processes can cause significant dysphagia. Endocrine disorders and metabolic derangements are systemic conditions that affect multiple organ systems. They contribute to the development of neuropathies, myopathies, and motility disorders that lead to swallowing difficulty...

BACKGROUND: According to prevailing views in neuroscience, near-death experiences (NDE) occurring after severe head trauma, critical illness, or coma are often life-transforming experiences in which no awareness or sensory experience of any kind is possible. Although there are general patterns, each case is quite different from the other and requires accurate recording and reporting to potentially explain the phenomenon. AIM: This narrative study aimed to explore a pregnant woman's NDE due to complications from MERS-CoV...

INTRODUCTION: Dysphagia in post COVID-19 patients could be caused by several factors, including reduced pharyngolaryngeal coordination due to SARS-CoV-2 tropism to the central and/or peripheral nervous system. To our knowledge, this is the first reported case of COVID-19-related dysphagia successfully treated with botulinum toxin type A injection. CASE DESCRIPTION: We report the case of a patient with severe oropharyngeal dysphagia due to COVID-19 confirmed by fibre endoscopy...

BACKGROUND: Severe weakness associated with critical illness (CIW) is common. This narrative review summarizes the latest scientific insights and proposes a guide for clinicians to optimize the diagnosis and management of the CIW during the various stages of the disease from the ICU to the community stage. MAIN BODY: CIW arises as diffuse, symmetrical weakness after ICU admission, which is an important differentiating factor from other diseases causing non-symmetrical muscle weakness or paralysis...

BACKGROUND: Critical illness polyneuropathy (CIP) commonly occurs in critical care unit (CCU) patients, but timely diagnosis can be challenging. Therefore, new biomarkers, such as serum neurofilament light chain (sNfL), could help to improve early identification of patients with this condition. METHODS: CIP was diagnosed or excluded with neurological assessment and nerve conduction measurement in a prospective study of CCU patients. sNfL and secondary predictors for neuropathy (neuron-specific enolase (NSE), S100, folic acid, and vitamin B<inf>12</inf>) were measured at admission...

OBJECTIVE: To assess sociodemographic, medical complexity, and outcomes of persons receiving care at inpatient rehabilitation facilities (IRFs) with and without a diagnosis of COVID-19. DESIGN: A retrospective cohort study using electronic medical record (EMR) data from 138 IRFs across 34 states and Puerto Rico. SETTING: N/A. PARTICIPANTS: IRF EMR data for 212,663 patients discharged between 04/01/2020 and 05/31/2021 (N=212,663), of which 16,199 (COVID-19 group) had a primary or secondary COVID-19 diagnosis based upon ICD codes set (ICD-10 codes U07...

COVID-19 infection has had a profound impact on society. During the initial phase of the pandemic, there were several suggestions that COVID-19 may lead to acute and protracted neurologic sequelae. For example, peripheral neuropathies exhibited distinctive features as compared to those observed in critical care illness. The peripheral nervous system, lacking the protection afforded by the blood-brain barrier, has been a particular site of sequelae and complications subsequent to COVID-19 infection, including Guillain-Barre syndrome, myasthenia gravis, and small fiber neuropathy...

Weakness of limb and respiratory muscles that occurs in the course of critical illness has become an increasingly common and serious complication of adult and pediatric intensive care unit patients and a cause of prolonged ventilatory support, morbidity, and prolonged hospitalization. Two motor disorders that occur singly or together, namely critical illness polyneuropathy and critical illness myopathy, cause weakness of limb and of breathing muscles, making it difficult to be weaned from ventilatory support, commencing rehabilitation, and extending the length of stay in the intensive care unit, with higher rates of morbidity and mortality...

Neuromuscular symptoms may develop or persist after resolution of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Besides residual sensorimotor symptoms associated with acute neuromuscular complications of coronavirus disease-2019 (COVID-19), such as Guillain-Barré syndrome, critical illness neuromyopathy, and rhabdomyolysis, patients may report persistent autonomic symptoms, sensory symptoms, and muscle symptoms in the absence of these acute complications, including palpitations, orthostatic dizziness and intolerance, paresthesia, myalgia, and fatigue...

OBJECTIVES: Coronavirus disease 2019 (COVID-19) has neurologic manifestations associated with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This study aimed to retrospectively analyze SARS COVID-19 patients with neurological manifestations and identify patterns of presentation including the site of neuroaxis involvement, neuroimaging, and associated systemic involvement. METHODS AND SUBJECTS: This retrospective observational study was conducted at two tertiary care hospitals in western Rajasthan...

The coronavirus disease 2019 (COVID-19) pandemic has had an enormous impact on practically every aspect of daily life, and those with neuromuscular disorders have certainly not been spared. The effects of COVID-19 infection are far-reaching, going well beyond respiratory symptoms alone. From simple myalgias to debilitating critical illness neuromyopathies, we continue to learn and catalog the diverse pathologies presented by the severe acute respiratory syndrome coronavirus 2 (SARS - CoV-2) as it relates to the neuromuscular system...

Neurologists in both the inpatient and outpatient settings are increasingly using ultrasound to diagnose and manage common neurological diseases. Advantages include cost-effectiveness, the lack of exposure to ionizing radiation, and the ability to perform at the bedside to provide real-time data. There is a growing body of literature that supports using ultrasonography to improve diagnostic accuracy and aid in performing procedures. Despite the increasing utilization of this imaging modality in medicine, there has been no comprehensive review of the clinical applications of ultrasound in the field of neurology...

The recent developments in intensive care have resulted in improved survival rates of patients treated with acute organ deficiency. As a consequence, the rate of those who survive the acute phase and subsequently require protracted organ support due to persisting organ dysfunction has been growing. Several survivors display chronic health status deterioration leading to prolonged rehabilitation or nursing, and repeated hospitalizations. The condition developed following the survival of the acute phase and requiring long-lasting intensive care is frequently termed as chronic critical illness (CCI)...

Various conditions causing weakness associated with coronavirus disease 2019 (COVID-19) infection have been described, including cerebrovascular diseases, acute myelitis, Guillain-Barré syndrome, myasthenia gravis, critical illness myopathy and neuropathy, myositis, and rhabdomyolysis. We report an adult man presenting with an unusual etiology of weakness after a COVID-19 infection. Thyrotoxic hypokalemic periodic paralysis (THPP) was diagnosed from the presence of Graves' disease and hypokalemia because of intra-cellular potassium shifting...

BACKGROUND: Long-term data on ICU-survivors reveal persisting sequalae and a reduced quality-of-life even after years. Major complaints are neuromuscular dysfunction due to Intensive care unit acquired weakness (ICUAW). Quantitative MRI (qMRI) protocols can quantify muscle alterations in contrast to standard qualitative MRI-protocols. METHODS: Using qMRI, the aim of this study was to analyse persisting myostructural abnormalities in former ICU patients compared to controls and relate them to clinical assessments...

Our aim was to evaluate health-related quality-of-life (HRQoL) of the patients with critical illness neuropathy and/or myopathy after severe COVID-19 during their rehabilitation. The prospective cohort study included 157 patients (median age 64 years) admitted to rehabilitation. HRQoL was assessed the using European Quality 5-Dimensions questionnaire [EQ-5D index , range 0(or exceptionally less) to 1, and Visual Analogue Scale (VAS), range 0-100], which was completed by the patients at admission and discharge...

The rate at which obesity is becoming an epidemic in many countries is alarming. Obese individuals have a high risk of developing elevated intraocular pressure and glaucoma. Additionally, glaucoma is a disease of epidemic proportions. It is characterized by neurodegeneration and neuroinflammation with optic neuropathy and the death of retinal ganglion cells (RGC). On the other hand, there is growing interest in microbiome dysbiosis, particularly in the gut, which has been widely acknowledged to play a prominent role in the etiology of metabolic illnesses such as obesity...

BACKGROUND: The clinical presentation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can range from mild or moderate disease (80% of the cases) to severe disease (15%) requiring oxygen support, and critical disease (5%), associated with acute respiratory distress syndrome and admission to the intensive care unit (ICU). In critically ill patients, prone positioning can be used to optimize oxygenation. Although there is a favourable response to this strategy, being a life-saving measure, additional associated complications may appear, including compressive neuropathies...
