In normal muscle, TDP-43 is present in nuclei. In IBMPFD muscle, TDP-43 is additionally present as large inclusions within UBIs in muscle cytoplasm. TDP-43 inclusions were also found in 78% of sporadic inclusion body myositis (sIBM) muscles. [ncbi.nlm.nih.gov]

Presentation [ 1, 9 ] Muscle weakness is the usual presenting feature. It usually presents after the age of 50. The distribution is variable and can be both proximal and distal. [patient.info]

• Plethora

  VCP, a member of the AAA-ATPase gene family, associates with a plethora of protein adaptors to perform a variety of cellular processes including Golgi assembly/disassembly and regulation of the ubiquitin-proteasome system. [ncbi.nlm.nih.gov]

• Long Legs

  Knee-Ankle-Foot Orthosis A KAFO is a long-leg orthosis that spans the knee, the ankle, and the foot in an effort to stabilize the joints and assist the muscles of the leg. [ibmmyositis.com]

• Neck Flexor Muscle Weakness

  The phenotype of this chromosome 7q22.3-31.2 linked autosomal dominant muscle disease includes the onset of symptoms between the ages of 30 and 50 years and a slowly progressive proximal limb and neck flexor muscle weakness that remains benign. [journals.plos.org]

• Hearing Impairment

  Two family members also showed signs of early hearing impairment, which was confirmed to be sensorineural in one person, a symptom not yet described in the context of IBMPFD. [ncbi.nlm.nih.gov]

• Dysphasia

  "Both of these processes have a role in the disease process but which one occurs first and which has the dominant role is still debated " ( Needham and Mastaglia 2007). sIBM is not considered a fatal disease (baring complications - mostly dysphasia, generally [ibmmyositis.com]

[This is not my website] Return to top Treatment: Summary: Based upon research, no treatment is recognized as effective for sIBM (as of 2017). [ibmmyositis.com]

CONCLUSION: The mild benefits in muscle strength experienced by HIBM patients after IVIG treatment may be related to the provision of sialic acid supplied by IVIG. Other sources of sialic acid are being explored as treatment options for HIBM. [ncbi.nlm.nih.gov]

Management [ 1, 11 ] There is no effective treatment for the disease and few high-quality randomised controlled trials. [ 12 ] Treatment is challenging as the disease is typically resistant to standard immunotherapy. [patient.info]

Is there a treatment? Currently, there are no effective treatments for HIBM. Researchers at Hadassah, USC, UCLA, UCSD, Johns Hopkins University, Canada, NIH, and Japan are contributing towards finding an effective treatment. [hibm.org]

We ascertained a family in which five siblings presented with distal muscle weakness of unknown etiology. [ncbi.nlm.nih.gov]

Etiology Etiology of IBM is poorly understood. No causal gene has been identified but HLA-DR3 and 8-1 MHC genotypes have been shown to correlate with IBM susceptibility. Ageing and environmental factors are also surmised to play a triggering role. [orpha.net]

Electromyography of affected muscles have been interpreted to indicate chronic denervation/reinervation, implying a neurogenetic etiology ( 5 ), as well as a primary myopathic process ( 5, 6 ). [hmg.oxfordjournals.org]
