Early shoulder-girdle MRI findings in severe COVID-19-related intensive care unit-acquired weakness: a prospective cohort study.

ABSTRACT:

Objective

To describe clinical and early shoulder-girdle MR imaging findings in severe COVID-19-related intensive care unit-acquired weakness (ICU-AW) after ICU discharge.

Methods

A single-center prospective cohort study of all consecutive patients with COVID-19-related ICU-AW from November 2020 to June 2021. All patients underwent similar clinical evaluations and shoulder-girdle MRI within the first month and then 3 months (± 1 month) after ICU discharge.

Results

We included 25 patients (14 males; mean [SD] age 62.4 [12.5]). Within the first month after ICU discharge, all patients showed severe proximal predominant bilateral muscular weakness (mean Medical Research Council total score = 46.5/60 [10.1]) associated with bilateral, peripheral muscular edema-like MRI signals of the shoulder girdle in 23/25 (92%) patients. At 3 months, 21/25 (84%) patients showed complete or quasi-complete resolution of proximal muscular weakness (mean Medical Research Council total score > 48/60) and 23/25 (92%) complete resolution of MRI signals of the shoulder girdle, but 12/20 (60%) patients experienced shoulder pain and/or shoulder dysfunction.

Conclusions

Early shoulder-girdle MRI findings in COVID-19-related ICU-AW included muscular edema-like peripheral signal intensities, without fatty muscle involution or muscle necrosis, with favorable evolution at 3 months. Precocious MRI can help clinicians distinguish critical illness myopathy from alternative, more severe diagnoses and can be useful in the care of patients discharged from intensive care with ICU-AW.

Key points

• We describe the clinical and shoulder-girdle MRI findings of COVID-19-related severe intensive care unit-acquired weakness. • This information can be used by clinicians to achieve a nearly specific diagnosis, distinguish alternative diagnoses, assess functional prognosis, and select the more appropriate health care rehabilitation and shoulder impairment treatment.

Project description:Intensive care unit-acquired weakness (ICU-AW) is the most common neuromuscular impairment in critically ill patients. We discuss critical aspects of ICU-AW that have not been completely defined or that are still under discussion. Critical illness polyneuropathy, myopathy, and muscle atrophy contribute in various proportions to ICU-AW. Diagnosis of ICU-AW is clinical and is based on Medical Research Council sum score and handgrip dynamometry for limb weakness and recognition of a patient's ventilator dependency or difficult weaning from artificial ventilation for diaphragmatic weakness (DW). ICU-AW can be caused by a critical illness polyneuropathy, a critical illness myopathy, or muscle disuse atrophy, alone or in combination. Its diagnosis requires both clinical assessment of muscle strength and complete electrophysiological evaluation of peripheral nerves and muscles. The peroneal nerve test (PENT) is a quick simplified electrophysiological test with high sensitivity and good specificity that can be used instead of complete electrophysiological evaluation as a screening test in non-cooperative patients. DW, assessed by bilateral phrenic nerve magnetic stimulation or diaphragm ultrasound, can be an isolated event without concurrent limb muscle involvement. Therefore, it remains uncertain whether DW and limb weakness are different manifestations of the same syndrome or are two distinct entities. Delirium is often associated with ICU-AW but a clear correlation between these two entities requires further studies. Artificial nutrition may have an impact on ICU-AW, but no study has assessed the impact of nutrition on ICU-AW as the primary outcome. Early mobilization improves activity limitation at hospital discharge if it is started early in the ICU, but beneficial long-term effects are not established. Determinants of ICU-AW can be many and can interact with each other. Therefore, future studies assessing early mobilization should consider a holistic patient approach with consideration of all components that may lead to muscle weakness.

Project description:BackgroundIntensive care unit-acquired weakness is a prevalent complication among critically ill patients, associated with heightened mortality rates, extended durations of mechanical ventilation and hospital stays, as well as diminished mobility and unfavorable prognoses. Early diagnosis of intensive care unit-acquired weakness and identification of its subcategories are essential for early implementation of targeted interventions and care strategies. Nevertheless, there remains a significant gap in the availability of widely accepted, accurate, and user-friendly diagnostic tools for intensive care unit-acquired weakness.ObjectiveThe aim of this research was to conduct a comprehensive review of pertinent studies on diagnostic tools for intensive care unit-acquired weakness in critically ill patients, summarizing their diagnostic efficacy and constraints to aid healthcare professionals in choosing suitable diagnostic tools for intensive care unit-acquired weakness.MethodsThe Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement were utilized to direct the literature search, bias risk assessment and data extraction. The search databases included PubMed, Web of Science, EMBASE, Cochrane Library, and CINAHL. The search period was from the inception of the database to 1 July 2024. Different types of risk bias assessment tools were used for different types of studies. Due to the heterogeneity of the data, solely a narrative synthesis of the intensive care unit-acquired weakness diagnostic tool was performed in this study.ResultsA total of 38 observational studies were included in the study. In the included studies, the gold standard for intensive care unit-acquired weakness diagnosis include the Medical Research Council score, muscle biopsy and electrophysiologic testing, potential diagnostic tools include the manual muscle test, electrophysiologic testing, imaging, serum inflammatory markers, neuromuscular ultrasound, and other parameters. In various studies, the diagnostic accuracy of intensive care unit-acquired weakness diagnostic tools has been inconsistent, with each tool possessing its own set of advantages and disadvantages. At present, no single tool is available for the definitive diagnosis of intensive care unit-acquired weakness, necessitating the combined use of multiple methods, each with inherent limitations. Manual muscle test is inexpensive and straightforward to perform, but it requires the patient to be conscious and cooperative. Muscle biopsy is invasive and rarely utilized. Electrophysiological testing can help differentiate whether intensive care unit-acquired weakness is caused by neural or muscular alterations, thereby aiding in the classification of its subtypes. However, it is moderately invasive, costly, and operator-dependent. Other diagnostic modalities, such as imaging and respiratory parameters, are under ongoing investigation.ConclusionsThe diagnostic tools available in intensive care unit-acquired weakness are varied, each with its own strengths and limitations. This study summarizes the current evidence on potential diagnostic tools for intensive care unit-acquired weakness and identifies possible future directions for these diagnostic tools.RegistrationPROSPERO Registration Number CRD42024573139.
