Disease Understanding and Diagnostic Algorithm

Inflammatory Myositis Overview

Inflammatory myopathies are rare and can affect both adults and children. Patients with inflammatory myopathies typically present with sub-acute to the chronic onset of proximal weakness manifested by difficulty rising from a chair, climbing stairs, lifting objects, and combing hair, among others.

Inflammatory Myositis Diagnosis

Diagnosing inflammatory myositis is challenging, particularly in the early stages when the symptoms are nonspecific. Diagnosis of inflammatory myositis is complicated because, despite appropriate diagnostic investigation, no uniform diagnostic criteria are available. The existing diagnostic criteria for inflammatory myositis, such as the Bohan and Peter criteria for dermatomyositis, have limitations. These criteria rely on a combination of clinical, laboratory, and histopathological features, which can be subjective and lack sensitivity and specificity. Developing updated and more refined diagnostic criteria can improve diagnostic accuracy and reduce misdiagnosis.

Currently, imaging techniques, such as magnetic resonance imaging, can assist in diagnosing inflammatory myositis by visualizing muscle inflammation. Invasive procedures, such as muscle biopsies, are currently required for definitive diagnosis of inflammatory myositis. However, there is still a need for more sensitive and specific imaging modalities that can accurately detect and quantify muscle inflammation, differentiate between different muscle pathologies, and assess disease activity. Developing noninvasive diagnostic tools, such as blood tests or imaging-based approaches, that can accurately identify and differentiate inflammatory myositis subtypes would be valuable in reducing the need for invasive procedures.

Inflammatory Myositis Epidemiology

For the purpose of designing the patient-based model for Inflammatory Myositis (OSA), the report provides historical as well as forecasted epidemiology segmented by Total Diagnosed Prevalent Cases of Inflammatory Myositis, Type-specific Diagnosed Prevalent cases of Inflammatory Myositis, Gender-specific Diagnosed Prevalent cases of Inflammatory Myositis, Age-specific Diagnosed Prevalent cases of Inflammatory Myositis, in the 7MM covering the United States, EU4 countries (Germany, France, Italy, and Spain) and the United Kingdom, and Japan, from 2020 to 2034. As per the analyst's estimations, the total diagnosed prevalent cases of Inflammatory Myositis in the 7MM were approximately 184 thousand cases in 2022 and are projected to increase during the forecast period.

• The overall count of individuals diagnosed with Inflammatory Myositis in the United States was approximately 90 thousand in 2022, and it is expected to increase at an estimated CAGR throughout the study period (2020-2034). The anticipated future rise in Inflammatory Myositis cases may stem from factors like increased awareness, aging population, environmental triggers, genetic predisposition, autoimmune factors, improved survival, and changing lifestyles.
• Among the 7MM, EU4 and the UK accounted for nearly 37% diagnosed prevalent cases of Inflammatory Myositis, and these cases are expected to increase during the forecast period (2023-2034).
• Among EU4 and the UK, Germany had the highest diagnosed prevalent population of Inflammatory Myositis, accounting to 32%, followed by the Italy (22%) and the UK (20%) in 2022. On the other hand, Spain had the lowest diagnosed prevalent population in EU4 and the UK in 2022.
• In Japan, there were around 26 thousand diagnosed prevalent cases of Inflammatory Myositis in 2022. These cases are expected to increase at a significant CAGR.
• The primary types of inflammatory myositis are Polymyositis, Dermatomyositis, and Inclusion Body Myositis (IBM). Each present distinct symptoms, including muscle weakness, skin rashes, and specific patterns of muscle involvement. In 2022, within the EU4 and the UK, Polymyositis had the highest percentage, representing approximately 51% of the total diagnosed inflammatory myositis cases.
• Gender-specific diagnosed prevalent cases of Inflammatory Myositis showed that females were more affected by Inflammatory Myositis than males in the 7MM in 2022. The higher prevalence of Inflammatory Myositis in females compared to males may be attributed to hormonal influences, genetic predispositions, and differences in immune responses between sexes.
• Assessments as per estimates suggest that among age groups 0-17 years, 18-44 years, 45-64 years, and 65 years and above, a higher number of diagnosed prevalent cases of inflammatory myositis were found in the age group of 45-64 years accounting for 46% of the cases in the US, in 2022.
• The highest proportion of Inflammatory Myositis cases was estimated in the 80 years and above age group in the 7MM, while the least cases were in the age group 40-49 years. Inflammatory Myositis is highly prevalent in geriatric population, while the disease appears rare below this age group.
