Proteomic study of sporadic inclusion body myositis

Ongoing Developments in Sporadic Inclusion Body Myositis

Sporadic inclusion body myositis (IBM) is an acquired muscle disorder associated with ageing, for which there is no effective treatment. Ongoing developments include: genetic studies that may provide insights regarding the pathogenesis of IBM, improved histopathological markers, the description of a new IBM autoantibody, scrutiny of the diagnostic utility of clinical features and biomarkers, th...

Sporadic inclusion body myositis: a continuing puzzle.

There is now compelling evidence that sporadic inclusion body myositis (sIBM) is a muscle-specific autoimmune disease in which both T and B-cells play a part and in which both cytotoxic muscle fibre necrosis and degeneration occur. However the factors responsible for breakdown of immune tolerance and the nature of the target antigens expressed by muscle fibres remain unknown. Genetic factors ar...

Long-term observational study of sporadic inclusion body myositis.

We describe a long-term observational study of a large cohort of patients with sporadic inclusion body myositis and propose a sporadic inclusion body myositis weakness composite index that is easy to perform during a clinic. Data collection from two groups of patients (Paris and Oxford) was completed either during a clinic visit (52%), or by extraction from previous medical records (48%). One h...

Sporadic inclusion body myositis: an unsolved mystery.

Sporadic inclusion body myositis (sIBM) is considered to be the most common acquired muscle disease associated with aging. It is a disabling disorder still without effective treatment. sIBM causes weakness and atrophy of the distal and proximal muscles. Involvement of quadriceps and deep finger flexors are clues to early diagnosis. Dysphagia in the course of the disease is common. Muscle biopsy...
