Semin Arthritis Rheum 2024; 68:152519. [PMID: 39059155 DOI: 10.1016/j.semarthrit.2024.152519] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2024] [Revised: 06/18/2024] [Accepted: 07/08/2024] [Indexed: 07/28/2024]
Abstract
BACKGROUND Muscle biopsy is an important test in the evaluation of individuals with suspected myopathy, including those with suspected idiopathic inflammatory myopathy (IIM). Various approaches, including open surgical biopsy, needle biopsy and conchotome forceps, have been reported. However the real-world utilisation of these approaches remains unclear. There are no established guidelines for the use of muscle biopsy, or selection of biopsy technique, in investigating IIM and international practices are not well-documented. This study describes current approaches to muscle biopsy amongst clinicians with expertise in IIM. METHODS A survey regarding muscle biopsy practices was disseminated among members of the International Myositis Assessment and Clinical Studies (IMACS) group. Data were analysed using descriptive statistics. RESULTS One-hundred and sixteen clinicians completed the survey, primarily rheumatologists. Open surgical biopsy was the most commonly employed technique (74.5 %), followed by needle (11.3 %) and conchotome (9.4 %) approaches. Clinical examination was the most common method of muscle selection, with 85.2 % of respondents reporting they 'always or almost always' relied on it. MRI and electromyography were also frequently utilised for muscle selection (51.9 %, 45.4 % respectively). There was variability in the perceived utility of muscle biopsy in certain clinical contexts, such as presence of myositis specific antibodies or cutaneous manifestations of dermatomyositis. While respondents generally reported low complication rates following muscle biopsy, non-diagnostic histopathology was commonly reported, regardless of procedural approach. CONCLUSION Clinicians managing IIM report muscle biopsy to be well tolerated however, non-diagnostic results are common. Substantial heterogeneity regarding perceived indications for biopsy, procedural approaches, and muscle selection strategies were observed within this expert group. Future research is needed to establish best practice and determine the role of muscle biopsy in the context of continued advancements in serological profiling of IIM.

[PMID: 36734037 PMCID: PMC10946625 DOI: 10.1111/nan.12888] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2022] [Revised: 01/26/2023] [Accepted: 01/28/2023] [Indexed: 02/04/2023]
Abstract
AIMS Muscle biopsy techniques range from needle muscle biopsy (NMB) and conchotome biopsy to open surgical biopsy. It is unknown whether specific biopsy techniques offer superior diagnostic yield or differ in procedural complication rates. Therefore, we aimed to compare the diagnostic utility of NMB, conchotome and open muscle biopsies in the assessment of neuromuscular disorders. METHODS A systematic literature review of the EMBASE and Medline (Ovid) databases was performed to identify original, full-length research articles that described the muscle biopsy technique used to diagnose neuromuscular disease in both adult and paediatric patient populations. Studies of any design, excluding case reports, were eligible for inclusion. Data pertaining to biopsy technique, biopsy yield and procedural complications were extracted. RESULTS Sixty-four studies reporting the yield of a specific muscle biopsy technique and, or procedural complications were identified. Open surgical biopsies provided a larger tissue sample than any type of percutaneous muscle biopsy. Where anaesthetic details were reported, general anaesthesia was required in 60% of studies that reported open surgical biopsies. Percutaneous biopsies were most commonly performed under local anaesthesia and despite the smaller tissue yield, moderate- to large-gauge needle and conchotome muscle biopsies had an equivalent diagnostic utility to that of open surgical muscle biopsy. All types of muscle biopsy procedures were well tolerated with few adverse events and no scarring complications were reported with percutaneous sampling. CONCLUSIONS When a histological diagnosis of myopathy is required, moderate- to large-gauge NMB and the conchotome technique appear to have an equivalent diagnostic yield to that of an open surgical biopsy.

Abstract
Introduction/Aims Currently, there are no straightforward guidelines for the clinical and diagnostic management of hyperCKemia, a frequent and nonspecific presentation in muscle diseases. Therefore, we aimed to describe our diagnostic workflow for evaluating patients with this condition. Methods We selected 83 asymptomatic or minimally symptomatic patients with persistent hyperCKemia for participation in this Italian multicenter study. Patients with facial involvement and distal or congenital myopathies were excluded, as were patients with suspected inflammatory myopathies or predominant respiratory or cardiac involvement. All patients underwent a neurological examination and nerve conduction and electromyography studies. The first step of the investigation included a screening for Pompe disease. We then evaluated the patients for myotonic dystrophy type II–related CCTG expansion and excluded patients with copy number variations in the DMD gene. Subsequently, the undiagnosed patients were investigated using a target gene panel that included 20 genes associated with isolated hyperCKemia. Results Using this approach, we established a definitive diagnosis in one third of the patients. The detection rate was higher in patients with severe hyperCKemia and abnormal electromyographic findings. Discussion We have described our diagnostic workflow for isolated hyperCKemia, which is based on electrodiagnostic data, biochemical screening, and first‐line genetic investigations, followed by successive targeted sequencing panels. Both clinical signs and electromyographic abnormalities are associated with increased diagnostic yields.

Impact of muscle biopsy on diagnosis and management of children with neuromuscular diseases: A 10-year retrospective critical review. J Pediatr Surg 2018; 53:489-492. [PMID: 28651826 DOI: 10.1016/j.jpedsurg.2017.06.006] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2017] [Revised: 06/01/2017] [Accepted: 06/11/2017] [Indexed: 11/30/2022]
Abstract
BACKGROUND Muscle biopsy facilitates morphologic, biochemical, and ultrastructural analysis of muscle for the purpose of making definitive neuromuscular diagnosis. However, muscle biopsy is an expensive, invasive, time-consuming, and resource-dependent procedure. The need for general anesthesia in children also increases the risks associated with this procedure. The aim of this study was to investigate the benefits of muscle biopsies performed over a 10-year period, with a focus on indications, suspected and histopathologic diagnosis, and impact on diagnosis and management decisions. METHODS We retrospectively reviewed results of muscle biopsies performed in children at our center during the 2004 to 2014 study period. Clinical presentations, biopsy complications, pathologic results, and changes in management decision were reviewed and analyzed. RESULTS Biopsies from 92 patients were included. Mean age of patients was 7.1years, and 66.3% were male. There were no perioperative complications, and definitive diagnosis was made in 74 patients. Regardless of whether pathologic changes were found or not, information gained from muscle biopsy significantly impacted prognosis and subsequent genetic counseling. CONCLUSIONS Muscle biopsy is a safe and useful diagnostic tool in children suspected of having neuromuscular diseases, especially in those with muscle diseases. Definitive pathologic diagnosis helps to optimize treatment, counseling, and surveillance. THE TYPE OF STUDY AND LEVEL OF EVIDENCE Study of diagnostic test: level 1.
