Is fibrodysplasia ossificans progressiva an interleukin-1 driven auto-inflammatory syndrome?

Fibrodysplasia ossificans progressiva (FOP) is the most catastrophic form of heterotopic ossification, due to ongoing intracellular signaling through the bone morphogenic protein pathway. The paroxysmal appear...

Rationale: Fibrodysplasia ossificans progressiva (FOP) is rare genetic disease featuring progressive heterotopic ossification of soft tissues of the musculoskeletal system which leads to severe disability and premature death. Recognition of this disease is important since invasive diagnostic procedures can promote disease progression. However, despite its distinctive clinical manifestations, diagnosis can be difficult because of its rarity Patient concerns: A 20-year-old woman was referred to rheumatology clinic for management of “ankylosing spondylitis”. The patent had begun to have hard subcutaneous nodu...

Abstract Fibrodysplasia ossificans progressiva (FOP) and diffuse intrinsic pontine glioma (DIPG) are diseases that typically manifest in childhood and are associated with severely reduced life expectancy. However, there are currently no effective therapies for these diseases, which remain incurable. Activin receptor-like kinase-2 (ALK2), encoded by the ACVR1 gene, is a bone morphogenetic protein (BMP) type-I receptor subtype that plays an important physiological role in the development of bones, muscles, brain, and other organs. Constitutively active mutants of ALK2 have been identified as causative of FOP and inv...

In conclusion, available reports suggest no contraindication to radiotherapy in FOP patients; although the number of cases was small, systematic toxicity reports often were not available, and none of the reports described high-dose, high-energy radiation treatment at locations such as muscle and joint regions.

Fibrodysplasia ossificans progressiva (FOP) is a rare hereditary disorder causing neck stiffness, ankylosis of temporomandibular joints, and severe restrictive respiratory dysfunction due to progressive heterotopic ossification of the connective tissue. Herein, we report a case of successful airway and anesthesia management using a high-flow nasal cannula (HFNC) in a 51-year-old man with FOP undergoing partial bone resection of the right greater trochanter of the femur. Although general anesthesia with awake fiberoptic nasotracheal intubation has been described as the gold standard, HFNC may yield another potentially viabl...

We thank Dr Dulski and Dr Slawek for sharing their fascinating case of pseudodystonia due to fibrodysplasia ossificans progressiva (FOP), a connective tissue disorder characterised by heterotopic ossification in muscles, tendons and ligaments. The patient presented with abnormal neck postures suggestive of cervical dystonia and further developed abnormal trunk and limb postures. Considering imaging evidence of inflammation in the sternocleidomastoid muscles, the abnormal postures were characterised within the spectrum of pseudodystonia rather than dystonia.
