Fibrodysplasia ossificans progressiva: disabling but now treatable

Keen Richard , Jacobs Benjamin , Mughal M Zulf

Background: Fibrodysplasia ossificans progressiva (FOP) is a rare condition characterised by congenital malformation of the great toes and progressive heterotopic endochondral ossification. The disease progresses with episodic flare-ups, resulting in disabling cumulative immobility. The discovery of the ACVR1 gene as the cause of FOP has allowed identification of therapeutic targets. Palovarotene, a retinoic acid receptor gamma agonist, is in phase 2 clinical trials.<...

Uptake of influenza vaccine in UK patients with fibrodysplasia ossificans progressiva

Gak Nataliya , Vinton Jacqueline , Jacobs Benjamin , Keen Richard

Fibrodysplasia ossificans progressiva (FOP; OMIM #135100) begins in childhood and leads to irreversible restriction of movement, functional impairment, and shortened life-span. Individuals with FOP develop progressive limitations in chest expansion, resulting in restrictive lung disease. Current management guidelines published in 2011 (1) highlight that Influenza may be a causative factor for FOP flare-ups, and can also cause potentially deadly cardiopulmonary complications, e...

Phalangeal microgeodic disease: A rare cause of painful swollen toes

Govindan Ranjith , Green Ruth , Dyankova-Peeva Daniela , Keen Richard , Jacobs Benjamin

A healthy 8-year-old girl of Nigerian origin, presented in January 2014 with a 2 month history of progressive pain and swelling of the right 2nd, 3rd and 4th toe. There was no preceding trauma or illness. Those toes were swollen, tender and cold to touch, with bluish skin discoloration (Figure 1).She had normal peripheral pulses. Her inflammatory markers were normal, as was haemoglobin electrophoresis. A Doppler ultrasoun...

Chronic recurrent multifocal osteomyelitis: the value of whole-body MRI in a series of 34 children

Jacobs Benjamin , Brown Mathew , Guha Ananya , Alexandrou Dion , Paul O'Donnell , Keen Richard

Objectives: To assess the role of whole-body MRI in the diagnosis and management of chronic recurrent multifocal osteomyelitis (CRMO) is a benign and non-infective auto-inflammatory bone disorder characterised by multiple and recurrent inflammatory bone lesions. No universal diagnostic criteria exist.Methods: Retrospective review of CRMO cases diagnosed at this hospital between 2008 and 2014. Cases were identified from patient records and clinical inform...

A slow and difficult diagnosis of a child with chronic recurrent multifocal osteomyelitis

Guha Ananya , Brown Mathew , Green Ruth , Keen Richard , Calder Peter , Jacobs Benjamin

Background: Chronic recurrent multifocal osteomyelitis (CRMO) is an auto-inflammatory bone disorder that has been difficult to diagnose in the past. Diagnosis used to depend on bone biopsy but can now be made with whole-body MRI scan.Presenting problem: A 9-year-old healthy girl had a 2-year history of pain, swelling, redness and heat in her right foot following a fall from bars in the park. She had an X-ray of her foot on the day of injury which was rep...

Classical SATB2-associated syndrome with severe osteoporosis, recurrent bony fractures and tibial bowing

Jacobs Benjamin , Rose Anna M. , Zulf Mughal M. , Keen Richard , Wakeling Emma L.

Background: Mutations in SATB2 have been described in association with a unique phenotype known as SATB2-associated syndrome (SAS). This condition is characterised by severe intellectual disability affecting speech development, behaviour, facial features and dental anomalies. Skeletal features and osteoporosis have been reported in older individuals (aged 15–36), in association with point mutations. We report a 24-year-old man with a SATB2 misse...

The treatment of Camurati-Engelmann disease with Losartan: a case report

Moylan Alex , Wakeling Emma L. , Mughal M. Zulf , Keen Richard , Thornton Matt , Peeva Daniela , Jacobs Benjamin

Background: Camurati-Engelmann disease (CED) is a rare bone dysplasia characterised by hyperostosis and sclerosis of the diaphyses of the long bones and skull. It is caused by autosomal dominant gain-of function mutations within TGFB1, which result in increased activity of transforming growth factor β1 (TGF-β1). It typically presents in mid-childhood with bone pain, myopathy and progressive immobility. Evidence for treatment is based on a number of case repo...

Fibrodysplasia ossificans progressiva: baseline characteristics of 101 subjects participating in a global, longitudinal, natural history study

Kaplan Frederick S , Hsiao Edward C , Baujat Genevieve , Brown Matthew A , De Cunto Carmen , Di Rocco Maja , Keen Richard , Al Makkadam Mona , Grogan Donna R , Pignolo Robert J

Objectives: Progressive heterotopic ossification in fibrodysplasia ossificans progressiva (FOP; OMIM #135100) begins in childhood and leads to irreversible restriction of movement, functional impairment, and shortened life-span. Baseline data from an on-going, global, 3-year, natural history study (NHS) describe FOP disease characteristics, and retrospective flare-up history, causes/symptoms, and outcomes.Methods: Data from 101 subjects (recruited from 2...

Palovarotene inhibits the development of new heterotopic ossification in fibrodysplasia ossificans progressiva (FOP)

Kaplan Frederick , Hsiao Edward C , Baujat Genevieve , Keen Richard , De Cunto Carmen , Di Rocco Maja , Brown Matthew A , Al Mukaddam Mona M , Grogan Donna R , Pignolo Robert J

Objective: FOP is a rare, severely disabling disease characterized by episodic flare-ups and accumulation of heterotopic ossification (HO) leading to restricted movement, physical disability, and early death. Data from two Phase 2 interventional studies and one natural history study (NHS) were used to evaluate whether palovarotene could reduce HO following an FOP flare-up.Methods: HO volume at the flare-up site was determined by CT at baseline and 12 wee...
