D Senger, F Erbguth
An average of 50-80% of patients treated in the intensive care unit is affected by disturbances of neuromuscular functions due to damage to the nerves and muscles, which has led to the terms critical illness polyneuropathy and myopathy. Both components occur in 30-50% of patients, while the others predominantly show a pure myopathy, while pure neuropathy is rare. Meanwhile, the descriptive term of the concept as intensive care unit-acquired weakness (ICUAW) is preferred. The most significant risk factors for the development of ICUAW are sepsis, multiorgan dysfunction and acute respiratory distress syndrome (ARDS)...

Acute neuromuscular paralysis (ANMP) is a clinical syndrome characterized by rapid onset muscle weakness progressing to maximum severity within several days to weeks (less than 4 wk). Bulbar and respiratory muscle weakness may or may not be present. It is a common neurological emergency which requires immediate and careful investigations to determine the etiology because accurate diagnosis has significant impact on therapy and prognosis. Respiratory failure caused by neuromuscular weakness is considered as more critical than lung disease because its development may be insidious or subtle until sudden decompensation leads to life threatening hypoxia...

The present study aimed to investigate the effects of acute sepsis on diaphragm contractility and relaxation, via examining the Ca2+‑uptake function of sarco/endoplasmic reticulum Ca2+ adenosine triphosphatase (SERCA), and the protein levels of SERCA1, SERCA2 and the ryanodine receptor (RyR) of the sarcoplasmic reticulum (SR). A sepsis rat model was established through cecal ligation and puncture (CLP). A total of 6 and 12 h following CLP, the isometric contractile and relaxation parameters of the diaphragm were measured...

The main aim of this study was to investigate factors associated with a delayed-onset posttraumatic stress disorder (PTSD) after the intensive care unit (ICU) treatment of patients with a chronic critical illness (CCI). Patients (n = 97) with critical illness polyneuropathy or critical illness myopathy were interviewed via the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, 4th Edition. The diagnosis of the acute stress disorder was assessed within 1 month (t1), the diagnosis of PTSD at 3 (t2) and 6 (t3) months after transfer from the acute care ICU to the post-acute ICU...

INTRODUCTION: We sought to determine the specificity of compound muscle action potential (CMAP) durations and amplitudes in a large critical illness neuromyopathy (CINM) cohort relative to controls with other neuromuscular conditions. METHODS: Fifty-eight patients with CINM who had been seen over a 17-year period were retrospectively studied. Electrodiagnostic findings of the CINM cohort were compared with patients with axonal peripheral neuropathy and myopathy due to other causes...

BACKGROUND: Critical illness polyneuropathy and myopathy (CIPNM) frequently occur in intensive care unit (ICU) critically ill subjects; about 55-70% of subjects achieve full recovery. CIPNM can occur in ICU subjects with severe acquired brain injury (sABI), but no data have been reported regarding their outcome. AIM: The aim of the present study was to investigate the functional recovery in subjects suffering from both CIPNM and sABI and whether they had poorer outcome than those with sABI only...

Intensive care interventions involve periods of mechanical ventilation, sedation and complete mechanical silencing of patients. Critical illness myopathy (CIM) is an ICU-acquired myopathy that is associated with limb muscle weakness, muscle atrophy, electrical silencing of muscle and motor proteinopathy. The hallmark of CIM is a preferential muscle myosin loss due to increased catabolic and reduced anabolic activity. The ubiquitin proteasome pathway plays an important role, apart from recently identified novel mechanisms affecting non-lysosomal protein degradation or autophagy...

A 42-year-old patient presented with acute allodynia and hyperalgesia in her distal limbs, most severe in the innervation area of the ulnar nerve. The patient developed critical illness myopathy/polyneuropathy after septic shock 5 months prior to her presentation. After exclusion of differential diagnosis, "late onset small fiber neuropathy" after critical illness was diagnosed. Recent studies showed small fiber lesions during critical illness and in follow-up exams, where additionally neuropathic pain were proved...

Weakness, seizures, and encephalopathy have a broad differential diagnosis in patients with systemic lupus erythematosus (SLE). We present a case of a 26-year-old female with a recent diagnosis of SLE who experienced a clinical deterioration with quadriparesis, seizures, and encephalopathy. Her quadriparesis was found to be secondary to biopsy-proven hydroxychloroquine-induced myopathy with concomitant inflammatory myopathy. Her seizures and encephalopathy were suspected to be multifactorial in the setting of sepsis and critical illness with possible contributions from neuropsychiatric manifestations of SLE and macrophage activation syndrome...

Critical care and intensive care units (ICUs) have undergone dramatic changes and improvements in recent years, and critical care is today one of the fastest growing hospital disciplines. Significant improvements in treatments, removal of inefficient and harmful interventions, and introduction of advanced technological support systems have improved survival among critically ill ICU patients. However, the improved survival is associated with an increased number of patients with complications related to modern critical care...

BACKGROUND: Critical illness polyneuropathy (CIN) and critical illness myopathy (CIM), together "ICU-Acquired weakness (ICUAW)," occur frequently in septic patients. One of the proposed mechanisms for ICUAW includes prolonged inactivation of sodium channels. Propofol, used commonly in patients with acute respiratory failure (ARF), primarily acts via enhancement of GABAergic transmission but may also increase sodium channel inactivation, suggesting a potential interaction. METHODS: Electronic medical records and EMG reports of patients with ICUAW and a diagnosis of either sepsis, septicaemia, severe sepsis, or septic shock, concurrent with a diagnosis of acute respiratory failure (ARF), were retrospectively analyzed in a single center university hospital...

Critical illness myopathy (CIM) and neuropathy are underdiagnosed conditions within the intensive care setting and contribute to prolonged mechanical ventilation and ventilator wean failure and ultimately lead to significant morbidity and mortality. These conditions are often further subdivided into CIM, critical illness polyneuropathy (CIP), or the combination-critical illness polyneuromyopathy (CIPNM). In this review, we discuss the epidemiology and pathophysiology of CIM, CIP, and CIPNM, along with diagnostic considerations such as detailed clinical examination, electrophysiological studies, and histopathological review of muscle biopsy specimens...

INTRODUCTION: Critically ill patients often develop tetraparesis. It has been debated whether this is caused by neuropathy, myopathy, or both. The aim was to determine the incidence of myopathy and neuropathy in weak patients in the intensive care unit by performing several electrophysiological examinations, including quantitative electromyography (qEMG). METHODS: Forty-nine patients referred for electrophysiological examination because of suspected critical illness-related weakness underwent qEMG, nerve conduction studies, and direct muscle stimulation...

Although patients with Legionnaire's disease frequently develop alterations of consciousness, this is no more frequent than in patients hospitalized with other, equally severe forms of bacterial pneumonia. Legionella meningitis occurs rarely, if ever. Patients with Legionnaire's are susceptible to critical illness polyneuropathy/myopathy, as are other critically ill patients. Legionnaire's patients may develop MRI hyperdensities in the splenium of the corpus callosum, as may other patients with severe infections...

PURPOSE OF REVIEW: This article discusses the clinical features, pathophysiology, and management of toxic and endocrine myopathies. RECENT FINDINGS: Early detection and expeditious correction of metabolic disturbances in endocrinopathies such as Cushing syndrome, thyroid and parathyroid diseases, and acromegaly can minimize and prevent neurologic complications including myopathy. Recently proposed mechanisms of injury in patients with critical illness myopathy include inhibition of protein synthesis, mitochondrial dysfunction, disruption of the ubiquitin-proteasome system, oxidative stress, and disruption of intramuscular calcium homeostasis, which can cause a myosin-loss myopathy...

BACKGROUND: Critical illness myopathy (CIM) and polyneuropathy (CIP) are a common complication of critical illness. Both cause intensive-care-unit-acquired (ICU-acquired) muscle weakness (ICUAW) which increases morbidity and delays rehabilitation and recovery of activities of daily living such as walking ability. Focused physical rehabilitation of people with ICUAW is, therefore, of great importance at both an individual and a societal level. A recent systematic Cochrane review found no randomised controlled trials (RCT), and thus no supporting evidence, for physical rehabilitation interventions for people with defined CIP and CIM to improve activities of daily living...
