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...

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...

Acute transverse myelitis (ATM) is an upper motor neuron disease of the spinal cord, and concomitant association of peripheral polyneuropathy, particularly the axonal type, is rarely reported in children. Our cases presented with ATM complicated with axonal type polyneuropathy. Axonal type polyneuropathy may be caused by acute motor-sensory axonal neuropathy (AMSAN) or critical illness polyneuropathy and myopathy (CIPNM). These cases emphasize the need for nerve and muscle biopsies to make the differential diagnosis between AMSAN and CIPNM in patients with ATM complicated with axonal polyneuropathy...

OBJECTIVE: Hyperglycemia may occur in the patients affected by any kind of critical illness. This complication makes an adverse effect on the clinical outcome of these patients by causing polyneuropathy and myopathy. It has been recently shown that treatment of hyperglycemia with insulin administration significantly reduces the prevalence of critical illness polyneuropathy and myopathy (CIPNM) and on the other hand reduces the demand for long-term mechanical ventilation in the patients admitted to the ICU for more than 1 week...

PURPOSE: The ability to diagnose patients with critical illness polyneuromyopathy (CIPNM) is hampered by impaired patient sensorium, technical limitations, and the time-intensive nature of performing electrophysiological testing. Therefore, we sought to determine whether single nerve conduction studies (NCS) could accurately screen for CIPNM. METHODS: Critically ill patients at increased risk for developing CIPNM were identified. Bilateral NCS of six nerves, and concentric needle electromyography were performed within 24 h of meeting inclusion criteria, and subsequently on a weekly basis until CIPNM was diagnosed or the patient was discharged from the intensive care unit (ICU)...

INTRODUCTION: Critical illness polyneuropathy and/or myopathy (CIPNM) is a severe complication of critical illness. Retrospective data suggest that early application of IgM-enriched intravenous immunoglobulin (IVIG) may prevent or mitigate CIPNM. Therefore, the primary objective was to assess the effect of early IgM-enriched IVIG versus placebo to mitigate CIPNM in a prospective setting. METHODS: In this prospective, randomized, double-blinded and placebo-controlled trial, 38 critically ill patients with multiple organ failure (MOF), systemic inflammatory response syndrome (SIRS)/sepsis, and early clinical signs of CIPNM were included...

PURPOSE: The clinical characteristics of and treatment approaches for critical illness polyneuromyopathy (CIPNM) are reviewed. SUMMARY: CIPNM is an acute axonal sensory-motor polyneuropathy that tends to occur after the development of respiratory insufficiency in patients with systemic inflammatory response syndrome, sepsis, or multiple-organ dysfunction syndrome. Numerous mechanisms have been proposed to explain the pathophysiology of CIPNM, most of which are complex and not fully understood or proven...

Critical illness polyneuropathy and myopathy (CIPNM) frequently develops in patients hospitalized in intensive care units. The number of patients with CIPNM admitted to inpatient rehabilitation is increasing. The aim of this study was to comprehensively evaluate the outcome of their rehabilitation. Twenty-seven patients with CIPNM were included in the study. The diagnosis was established clinically and confirmed electrophysiologically. Manual muscle testing was used for the assessment of function. Activity was assessed using the functional independence measure and two walking tests...

Following critical illness requiring prolonged mechanical ventilation and sedation, intensive care patients often present with neuromuscular weakness. This results from critical illness polyneuropathy (CIP) and critical illness myopathy (CIM). A lack of diagnostic criteria for each syndrome complicates prevention and treatment. Consequently the term critical illness polyneuromyopathy (CIPNM) has emerged and is characterised by severe weakness, reduced or absent limb reflexes and marked muscle wasting. Although clinical trials report a high incidence of CIPNM, in clinical practice it often remains undetected...

INTRODUCTION: Critical illness polyneuromyopathy (CIPNM) is a common complication of critical illness presenting with muscle weakness and is associated with increased duration of mechanical ventilation and weaning period. No preventive tool and no specific treatment have been proposed so far for CIPNM. Electrical muscle stimulation (EMS) has been shown to be beneficial in patients with severe chronic heart failure and chronic obstructive pulmonary disease. Aim of our study was to assess the efficacy of EMS in preventing CIPNM in critically ill patients...

BACKGROUND: Critical illness polyneuropathy and myopathy (CIPNM) is recognized as a common condition that develops in the intensive care unit (ICU). It may lead to a prolonged hospital stay with subsequent increased ICU and hospital costs. Knowledge of predisposing factors is insufficient and the temporal pattern of CIPNM has not been well described earlier. This study investigated patients with critical illness in need of prolonged mechanical ventilation, describing comprehensively the time course of changes in muscle and nerve neurophysiology, histology and mitochondrial oxidative function...

Acquired neuromuscular weakness due to critical illness polyneuropathy and myopathy (CIPNM) frequently develops in patients hospitalized in the intensive care unit for more than 1 week. CIPNM may present with muscle weakness and failure to wean from mechanical ventilation, but is discovered more often and earlier by electrophysiological examination. In this review, the incidence, clinical and electrophysiological features, differential diagnosis and prognosis of CIPNM will be described. Risk factors for CIPNM are sepsis or systemic inflammatory response syndrome and the severity of multi-organ failure...

Critical-illness polyneuropathy and myopathy (CIPNM) can be considered a part of the syndrome of multiple organ dysfunction. CIPNM is the commonest cause of muscle weakness acquired in the intensive care unit. Its incidence is 35-80% during prolonged mechanical ventilation. For a (differential) diagnosis, electrophysiological investigations are usually necessary, and sometimes a muscle biopsy. CIPNM may be induced by triggering of the immune response leading to increased vascular permeability with tissue invasion of inflammatory cells and local damage...

In a longitudinal prospective study a muscle biopsy was taken from 30/32 (33%) of the 98 patients who developed critical illness polyneuropathy and myopathy (CIPNM). Neuropathic changes were found in 37%, myopathic in 40%, and a combination in 23% of the biopsies. The immunohistopathology showed macrophages and Th-cells in 40% and 60% of the muscle biopsies respectively. Small mainly perivascular infiltrates contained macrophages and Th-cells. ICAM-1, VCAM and MAC were found on the vascular endothelium in 58%, 53% and 79% respectively...
