Autoantibodies are important in the diagnosis of dermatomyositis. They can be divided in two different groups: myositis-associated autoantibodies (MAA) prevailing in overlap syndromes, and myositis-specific autoantibodies (MSA), with diagnostic specificity exceeding 90%. Our purpose was to detect retrospectively the prevalence of the most common MSAs in a group of 19 adult DM patients (13 women, 6 men). A severe DM (SDM), with extensive cutaneous and muscular manifestations, dysphagia, and sometimes pneumopathy, was detected in ten cases...

PURPOSE OF REVIEW: Inclusion body myositis (IBM) is an enigmatic progressive disease of skeletal muscle. This review provides a summary of the clinical and pathophysiologic aspects of IBM. RECENT FINDINGS: The development of diagnostic blood testing for IBM followed from the discovery of a B-cell pathway in IBM muscle and circulating autoantibodies against NT5C1A, further establishing IBM's status as an autoimmune disease. The key role of cytotoxic T cells in IBM is further supported by the identification of a link between IBM and T-cell large granular lymphocytic leukemia...

Extraintestinal manifestations are common in inflammatory bowel disease; however, muscular involvement in Crohn disease is rarely reported. We present a case of a 26-year-old male with ileocolonic Crohn disease who developed sudden tenderness in both calves. Doppler ultrasound was negative for deep vein thrombosis. Magnetic resonance imaging of the gastrocnemius muscle showed high intensity signal in the muscle fibers, and muscle biopsy demonstrated nonspecific lymphocytic myositis. Other relevant laboratory results included normal antineutrophil cytoplasmic antibodies and creatine kinase as well as elevated C-reactive protein, erythrocyte sedimentation rate, and anti-Saccharomyces cerevisiae IgG titer...

Inflammatory myopathies are a heterogeneous group of immune-mediated diseases that involve the skeletal muscle as well as many other organs. In addition to a histological diagnosis at muscle biopsy, the clinical phenotypes of inflammatory myopathies can be defined by the presence of various autoantibodies that are originally detected by RNA or protein immunoprecipitation. However, the correlation between histological features and autoantibodies has not been fully elucidated. Immune-mediated necrotizing myopathy (IMNM), which is characterized by significant necrotic and regeneration muscle fibers with minimal or no inflammatory cell infiltration, is associated with the presence of autoantibodies...

Idiopathic inflammatory myopathies are historically classified into polymyositis and dermatomyositis based on the presence or absence of skin lesions. Recently, however, a more histology-oriented classification into 6 subtypes has been proposed. The subtypes include dermatomyositis, polymyositis, inclusion body myositis, immune-mediated necrotizing myopathy, anti-synthetase syndrome, and non-specific myositis. With strict criteria applied, polymyositis is now extremely rare, while immune-mediated necrotizing myopathy is the most common among all inflammatory myopathies and is often associated with autoantibodies including those for signal recognition particle (SRP) or 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR)...

The standard of care for localized hepatocellular carcinoma (HCC) is surgical resection. For patients who decline or who are unfit for surgery, stereotactic body radiotherapy (SBRT) is emerging as a viable treatment approach. We present a case of a 77-year-old female in whom an early stage HCC was incidentally discovered. Given her religious edicts as a devout Jehovah's Witness and her subsequent desire to avoid a blood transfusion, she declined surgical resection or transplant due to the risk of hemorrhage...

Sporadic inclusion body myositis (sIBM) is a chronic progressive myopathy characterized by muscle weakness of both the quadriceps femoris and finger flexors. We herein present the case of a typical male patient with sIBM, which manifested as the isolated weakness of the finger flexors three years after the disease onset. We have identified several patients with sIBM in our cohort with muscle weakness of the flexors but not the quadriceps femoris. Examination of the flexor digitorum profundus muscle is important for the early and proper diagnosis of sIBM, even if a patient only presents with isolated finger flexor muscle weakness...

Inflammatory myopathies comprise heterogeneous, often multisystemic autoimmune diseases with muscle involvement as a common feature. The prognosis largely depends on a timely diagnosis and initiation of therapy. Given the complexity of these rare diseases, when an inflammatory myopathy is suspected patients should be referred to an expert center with established algorithms for the diagnostic work-up. The differential diagnostic exclusion of myositis mimics should ideally be carried out in close collaboration with neurologists and neuropathologists...

The coordination of macrophage polarization is essential for the robust regenerative potential of skeletal muscle. Repair begins with a phase mediated by inflammatory monocytes (IM) and proinflammatory macrophages (M1), followed by polarization to a proregenerative macrophage (M2) phenotype. Recently, regulatory T cells (Tregs) were described as necessary for this M1 to M2 transition. We report that chronic infection with the protozoan parasite Toxoplasma gondii causes a nonresolving Th1 myositis with prolonged tissue damage associated with persistent M1 accumulation...

BACKGROUND: Dystrophic calcifications may occur in patients with J uvenile Idiopathic Inflammatory Myopathy (JIIM) as well as other connective tissue and metabolic diseases, but a reliable method of measuring the volume of these calcifications has not been established. The purpose of this study is to determine the feasibility of low dose, limited slice, Computed Tomography (CT) to measure objectively in-situ calcification volumes in patients with JIIM over time. METHODS: Ten JIIM patients (eight JDM, two Overlap) with calcifications were prospectively recruited over a 2-year period to undergo two limited, low dose, four-slice CT scans...

A 79 year-old female was admitted to our hospital because of high serum creatine kinase level together with proximal muscle weakness and pain on grasping. MRI revealed inflammatory changes in femoral muscles on both sides. Muscle biopsy showed size irregularity of muscle cells, and necrosis and regeneration of fibers. Study of antibodies was also consistent with the diagnostic criteria of anti-signal recognition particle (anti-SRP) antibody-positive myopathy. On admission, the patient required pericardiocentesis for the management of exudative pericarditis...

REVIEW

Immune checkpoint inhibitors (ICIs) are increasingly studied and used as therapy for a growing number of malignancies. ICIs work by blocking inhibitory pathways of T-cell activation, leading to an immune response directed against tumors. Such nonspecific immunologic activation can lead to immune-related adverse events (IRAEs). Some IRAEs, including inflammatory arthritis, sicca syndrome, myositis, and vasculitis, are of special interest to rheumatologists. As use of ICIs increases, recognition of these IRAEs and developing treatment strategies will become important...

Intra-abdominal myositis ossificans, also known as heterotopic mesenteric ossification, defines the formation of bone-like lesions inside the abdominal cavity. It is a rare medical condition, usually following abdominal surgery or trauma. A 55-year-old male presented for closure of a Hartmann's colostomy, created 6 months ago because of sigmoid adenocarcinoma. Intraoperative findings consisted of an elongated bone-like lesion attached on the peritoneum and protruding inside the abdominal cavity, while two more stiff calcified nodules were found in the mesocolon...
