RESUMO
OBJECTIVES: Fibrodysplasia ossificans progressiva (FOP) is one of the most catastrophic forms of genetic heterotopic ossification (HO). FOP is characterized by severe, progressive inflammatory flare-ups, that often lead to HO. The flare-ups are associated with increased inflammatory cytokine production, suggesting auto-inflammatory features driven by interleukin-1ß (IL-1ß). This study describes the short- and long-term responses of FOP patients to anti-IL-1 therapy. METHODS: Previously, we reported that a patient with FOP treated with anti-IL-1 agents showed dramatically lower rates of flare-ups, improved flare-up symptoms, decreased use of glucocorticoids, and apparently decreased size of residual lesions. Plasma analyses also showed marked elevation in IL-1ß levels during a FOP flare, further supporting a role of IL-1ß in the pathogenesis of FOP flares. Here, we report results from long-term therapy with IL-1 inhibitors in that patient, and describe 3 additional patients, from two medical centers. RESULTS: All 4 patients showed persistent improvement in flare activity during treatment with IL-1 inhibitors, with minimal formation of new HO sites. Two patients who stopped therapy experienced resurgence of flare activity that was re-suppressed upon re-initiation. These patients had IL-1ß levels comparable to those in IL-1ß-driven diseases. Child Health Assessment Questionnaires confirmed extensive subjective improvements in the pain and general health visual analogue scales. CONCLUSION: This case series demonstrates significant benefits from IL-1 inhibitors for reducing flare activity and improving the general health of patients with FOP. These data provide strong support for additional studies to better understand the function of IL-1 inhibition, primarily in reducing formation new HO. FUNDING: RH received support from the International FOP Association ACT grant; ECH received support from NIH/NIAMS R01AR073015 and the UCSF Robert Kroc Chair in Connective Tissue and Rheumatic Diseases III.
RESUMO
BACKGROUND/PURPOSE: Adequate transition from pediatric to adult care is associated with better adherence to treatment and better outcomes in pediatric patients with chronic diseases. There are little data on transition programs, outcomes, use of transition guidelines, and available tools in pediatric rheumatology centers from Latin America (LATAM). In this study, we described the characteristics of transition programs from 3 pediatric rheumatology centers. We also introduced results of the first survey examining the transition experience in countries from LATAM. METHODS: The experience and implementation process of transition programs from 3 pediatric rheumatology centers were described. A survey based on a questionnaire created by Chira et al (J Rheumatol. 2014;41:768-779) from the Childhood Arthritis and Rheumatology Research Alliance was also administrated to pediatric rheumatology centers from LATAM. RESULTS: A total of 49 (68%) pediatric rheumatologists answered the survey. Most centers do not have an official and written transition program and reported a need for more tools and resources in their services to facilitate the transition experience. CONCLUSIONS: Transition guidelines culturally tailored to developing countries are needed in LATAM.
RESUMO
BACKGROUND: The design of clinical trials in rare diseases is often complicated by a lack of real-world translational knowledge. Fibrodysplasia ossificans progressiva (FOP) is an ultra-rare genetic disorder characterized by skeletal malformations and progressive heterotopic ossification (HO). Palovarotene is a selective retinoic acid receptor gamma agonist. Here, we describe the methodology of three studies in the palovarotene clinical development program in FOP and discuss insights that could inform future research, including endpoint suitability and the impact of trial design. METHODS: PVO-1A-001 (NCT02322255) was a prospective, protocol-specified, longitudinal FOP natural history study (NHS). PVO-1A-201 (NCT02190747) was a randomized, double-blind, placebo-controlled phase II trial; PVO-1A-202 (NCT02279095) was its open-label extension. Trial designs, including treatment regimens and imaging assessments, were refined between PVO-1A-201 and PVO-|1A-202, and within PVO-1A-202, based on emerging data as the studies progressed. Palovarotene doses were administered using a flare-up treatment regimen (higher dose for 2/4 weeks, followed by lower dose for 4/≥8 weeks; from flare-up onset), with or without accompanying chronic (daily) treatment. Flare-up and disease progression outcomes were assessed, including incidence and volume of new HO during flare-ups and/or annually, as well as other clinical, patient-reported, and exploratory outcomes. Safety was monitored throughout all studies. RESULTS: Overall, 114 and 58 individuals with FOP were enrolled in the NHS and phase II trials, respectively. Results of the NHS and PVO-1A-201 were published in 2022; complete results of PVO-1A-202 will be publicly available in due course. Together the studies yielded important information on endpoint suitability, including that low-dose whole-body computed tomography was the optimum imaging modality for assessing HO progression annually and that long study durations are needed to detect substantial changes in functional and patient-reported outcomes. CONCLUSIONS: A flexible clinical development program is necessary for underexplored rare diseases to overcome the many challenges faced. Here, the NHS provided a longitudinal evaluation of FOP progression and interventional trials were based on emerging data. The studies described informed the design and endpoints implemented in the phase III MOVE trial (NCT03312634) and provide a foundation for future clinical trial development. TRIAL REGISTRATION: NCT02322255 (registered 23/12/2014); NCT02190747 (registered 15/07/2014); NCT02279095 (registered 30/10/2014).

BACKGROUND: Fibrodysplasia ossificans progressiva (FOP) is an ultrarare genetic disorder with episodic and progressive heterotopic ossification. Tissue trauma is a major risk factor for flareups, heterotopic ossification (HO), and loss of mobility in patients with FOP. The International Clinical Council on FOP generally recommends avoiding surgery in patients with FOP unless the situation is life-threatening, because soft tissue injury can trigger an FOP flareup. Surprisingly little is known about flareups, HO formation, and loss of mobility after fractures of the normotopic (occurring in the normal place, distinct from heterotopic) skeleton when treated nonoperatively in patients with FOP. QUESTIONS/PURPOSES: (1) What proportion of fractures had radiographic evidence of union (defined as radiographic evidence of healing at 6 weeks) or nonunion (defined as the radiographic absence of a bridging callus at 3 years after the fracture)? (2) What proportion of patients had clinical symptoms of an FOP flareup because of the fracture (defined by increased pain or swelling at the fracture site within several days after closed immobilization)? (3) What proportion of patients with fractures had radiographic evidence of HO? (4) What proportion of patients lost movement after a fracture? METHODS: We retrospectively identified 36 patients with FOP from five continents who sustained 48 fractures of the normotopic skeleton from January 2001 to February 2021, who were treated nonoperatively, and who were followed for a minimum of 18 months after the fracture and for as long as 20 years, depending on when they sustained their fracture during the study period. Five patients (seven fractures) were excluded from the analysis to minimize cotreatment bias because these patients were enrolled in palovarotene clinical trials (NCT02190747 and NCT03312634) at the time of their fractures. Thus, we analyzed 31 patients (13 male, 18 female, median age 22 years, range 5 to 57 years) who sustained 41 fractures of the normotopic skeleton that were treated nonoperatively. Patients were analyzed at a median follow-up of 6 years (range 18 months to 20 years), and none was lost to follow-up. Clinical records for each patient were reviewed by the referring physician-author and the following data for each fracture were recorded: biological sex, ACVR1 gene pathogenic variant, age at the time of fracture, fracture mechanism, fracture location, initial treatment modality, prednisone use at the time of the fracture as indicated in the FOP Treatment Guidelines for flare prevention (2 mg/kg once daily for 4 days), patient-reported flareups (episodic inflammatory lesions of muscle and deep soft connective tissue characterized variably by swelling, escalating pain, stiffness, and immobility) after the fracture, follow-up radiographs of the fracture if available, HO formation (yes or no) as a result of the fracture determined at a minimum of 6 weeks after the fracture, and patient-reported loss of motion at least 6 months after and as long as 20 years after the fracture. Postfracture radiographs were available in 76% (31 of 41) of fractures in 25 patients and were independently reviewed by the referring physician-author and senior author for radiographic criteria of fracture healing and HO. RESULTS: Radiographic healing was noted in 97% (30 of 31) of fractures at 6 weeks after the incident fracture. Painless nonunion was noted in one patient who sustained a displaced patellar fracture and HO. In seven percent (three of 41) of fractures, patients reported increased pain or swelling at or near the fracture site within several days after fracture immobilization that likely indicated a site-specific FOP flareup. The same three patients reported a residual loss of motion 1 year after the fracture compared with their prefracture status. HO developed in 10% (three of 31) of the fractures for which follow-up radiographs were available. Patient-reported loss of motion occurred in 10% (four of 41) of fractures. Two of the four patients reported noticeable loss of motion and the other two patients reported that the joint was completely immobile (ankylosis). CONCLUSION: Most fractures treated nonoperatively in individuals with FOP healed with few flareups, little or no HO, and preservation of mobility, suggesting an uncoupling of fracture repair and HO, which are two inflammation-induced processes of endochondral ossification. These findings underscore the importance of considering nonoperative treatment for fractures in individuals with FOP. Physicians who treat fractures in patients with FOP should consult with a member of the International Clinical Council listed in the FOP Treatment Guidelines ( https://www.iccfop.org ). LEVEL OF EVIDENCE: Level IV, therapeutic study.

Nuestro objetivo fue conocer las características clínicas, el compromiso coronario y la evolución de pacientes atendidos en nuestra institución. Se revisó una serie de casos desde 2001 hasta 2018. Se incluyeron 63 pacientes, 58 % varones; la mediana de edad fue 2,6 años. La mediana de días de fiebre al diagnóstico fue 5,5 días. El 33 % presentó la forma incompleta y se detectó compromiso coronario en el 20 %. El 60 % de los pacientes con afectación coronaria presentaron EK incompleta versus el 28 % de presentación incompleta en los pacientes sin compromiso coronario (p 0,06). No se observaron diferencias en datos de laboratorio entre los grupos según el compromiso coronario. En conclusión, 33 % presentó EK incompleta y el 20 %, afectación coronaria. Hubo una tendencia de mayor riesgo para daño coronario en la forma incompleta.
Kawasaki disease (KD) is considered the leading cause of acquired heart disease in children younger than 5 years. Our objective was to know the clinical characteristics, coronary involvement, and course of patients seen at our facility. A case series from 2001 to 2018 was reviewed. Sixty-three patients were included; their median age was 2.6 years; 58% were males. The median duration of fever at the time of diagnosis was 5.5 days. The incomplete form was observed in 33% and coronary involvement, in 20%. Among patients with coronary involvement, 60% had incomplete KD versus 28% among those without coronary involvement (p: 0.06). No differences were observed between groups in laboratory data based on coronary involvement. To conclude, 33% had incomplete KD and 20%, coronary involvement. There was a trend to a higher risk for coronary artery damage in the incomplete form of KD.

Fibrodysplasia ossificans progressiva (FOP) is an ultra-rare, severely disabling genetic disorder of progressive heterotopic ossification (HO). The single-arm, open-label, phase 3 MOVE trial (NCT03312634) assessed efficacy and safety of palovarotene, a selective retinoic acid receptor gamma agonist, in patients with FOP. Findings were compared with FOP natural history study (NHS; NCT02322255) participants untreated beyond standard of care. Patients aged ≥4 years received palovarotene once daily (chronic: 5 mg; flare-up: 20 mg for 4 weeks, then 10 mg for ≥8 weeks; weight-adjusted if skeletally immature). The primary endpoint was annualized change in new HO volume versus NHS participants (by low-dose whole-body computed tomography [WBCT]), analyzed using a Bayesian compound Poisson model (BcPM) with square-root transformation. Twelve-month interim analyses met futility criteria; dosing was paused. An independent Data Monitoring Committee recommended trial continuation. Post hoc 18-month interim analyses utilized BcPM with square-root transformation and HO data collapsed to equalize MOVE and NHS visit schedules, BcPM without transformation, and weighted linear mixed-effects (wLME) models, alongside prespecified analysis. Safety was assessed throughout. Eighteen-month interim analyses included 97 MOVE and 101 NHS individuals with post-baseline WBCT. BcPM analyses without transformation showed 99.4% probability of any reduction in new HO with palovarotene versus NHS participants (with transformation: 65.4%). Mean annualized new HO volume was 60% lower in MOVE versus the NHS. wLME results were similar (54% reduction fitted; nominal p = 0.039). All palovarotene-treated patients reported ≥1 adverse event (AE); 97.0% reported ≥1 retinoid-associated AE; 29.3% reported ≥1 serious AE, including premature physeal closure (PPC)/epiphyseal disorder in 21/57 (36.8%) patients aged <14 years. Post hoc computational analyses using WBCT showed decreased vertebral bone mineral density, content, and strength, and increased vertebral fracture risk in palovarotene-treated patients. Thus, post hoc analyses showed evidence for efficacy of palovarotene in reducing new HO in FOP, but high risk of PPC in skeletally immature patients. © 2022 The Authors.

Introduction. The continuity of care from pediatrics to adult medicine is key to optimal health care. Objective. To describe the experience of the transition process of adolescent patients with chronic diseases from pediatric to adult care in a general hospital. Population and methods. Cross-sectional study of patients aged 1624 years with a history of liver transplantation, kidney transplantation, endocrine, metabolic, rheumatic diseases, and myelomeningocele seen at a tertiary care teaching general hospital between 2015 and 2019 during the transition process. The process of health care and transition success were assessed. The Transition Readiness Assessment Questionnaire (TRAQ) was used. Results. A total of 372 patients were included. The myelomeningocele clinic, the kidney transplant and the liver transplant teams were the most common specialties. Thirty-seven percent of participants were involved in the transition process. The mean duration of follow-up by pediatrics until transition initiation was 9 years. The mean age at the beginning of transition was 19 years, and the mean age at the end, 21 years. The joint clinic transition strategy was the most frequent, used in 96% of cases. The median value of the ordinal TRAQ was 4; of these, 32% had already seen adult care physicians. A successful transition was achieved by 32.7%. Conclusions. The continuity of care during transition is a process that took almost 2 years; more than one third of the patients had a successful transition.

PURPOSE: We report the first prospective, international, natural history study of the ultra-rare genetic disorder fibrodysplasia ossificans progressiva (FOP). FOP is characterized by painful, recurrent flare-ups, and disabling, cumulative heterotopic ossification (HO) in soft tissues. METHODS: Individuals aged ≤65 years with classical FOP (ACVR1R206H variant) were assessed at baseline and over 36 months. RESULTS: In total, 114 individuals participated; 33 completed the study (mean follow up: 26.8 months). Median age was 15.0 (range: 4-56) years; 54.4% were male. During the study, 82 (71.9%) individuals reported 229 flare-ups (upper back: 17.9%, hip: 14.8%, shoulder: 10.9%). After 84 days, 14 of 52 (26.9%) imaged flare-ups had new HO at the flare-up site (mean new HO volume: 28.8 × 103 mm3). Mean baseline low-dose whole-body computed tomography (excluding head) HO volume was 314.4 × 103 mm3; lowest at 2 to <8 years (68.8 × 103 mm3) and increasing by age (25-65 years: 575.2 × 103 mm3). The mean annualized volume of new HO was 23.6 × 103 mm3/year; highest at 8 to <15 and 15 to <25 years (21.9 × 103 and 41.5 × 103 mm3/year, respectively) and lowest at 25 to 65 years (4.6 × 103 mm3/year). CONCLUSION: Results from individuals receiving standard care for up to 3 years in this natural history study show the debilitating effect and progressive nature of FOP cross-sectionally and longitudinally, with greatest progression during childhood and early adulthood.

Fibrodysplasia ossificans progressiva (FOP) is a rare and devastating genetic disease, in which soft connective tissue is converted into heterotopic bone through an endochondral ossification process. Patients succumb early as they gradually become trapped in a second skeleton of heterotopic bone. Although the underlying genetic defect is long known, the inherent complexity of the disease has hindered the discovery of effective preventions and treatments. New developments in the gene therapy field have motivated its consideration as an attractive therapeutic option for FOP. However, the immune system's role in FOP activation and the as-yet unknown primary causative cell, are crucial issues which must be taken into account in the therapy design. While gene therapy offers a potential therapeutic solution, more knowledge about FOP is needed to enable its optimal and safe application.

Fibrodysplasia ossificans progressiva (FOP) is an ultra-rare progressive genetic disease effecting one in a million individuals. During their life, patients with FOP progressively develop bone in the soft tissues resulting in increasing immobility and early death. A mutation in the ACVR1 gene was identified as the causative mutation of FOP in 2006. After this, the pathophysiology of FOP has been further elucidated through the efforts of research groups worldwide. In 2015, a workshop was held to gather these groups and discuss the new challenges in FOP research. Here we present an overview and update on these topics.

Fibrodysplasia ossificans progressiva (FOP) is an ultra-rare genetic disorder that leads to heterotopic ossification (HO), resulting in progressive restriction of physical function. In this study, low-dose, whole-body computed tomography (WBCT) and dual energy X-ray absorptiometry (DXA) were evaluated to determine the preferred method for assessing total body burden of HO in patients with FOP. This was a non-interventional, two-part natural history study in patients with FOP (NCT02322255; date of registration: December 2014). In Part A (described here), WBCT and DXA scans were individually assessed for HO presence and severity across 15 anatomical regions. All images were independently reviewed by an expert imaging panel. Ten adult patients were enrolled across four sites. The sensitivity to HO presence and severity varied considerably between the two imaging modalities, with WBCT demonstrating HO in more body regions than DXA (76/138 [55%] versus 47/113 [42%]) evaluable regions). Inability to evaluate HO presence, due to overlapping body regions (positional ambiguity), occurred less frequently by WBCT than by DXA (mean number of non-evaluable regions per scan 1.2 [standard deviation: 1.5] versus 2.4 [1.4]). Based on the increased sensitivity and decreased positional ambiguity of low-dose WBCT versus DXA in measuring HO in patients with FOP, low-dose WBCT was chosen as the preferred imaging for measuring HO. Therefore, low-dose WBCT was carried forward to Part B of the natural history study, which evaluated disease progression over 36 months in a larger population of patients with FOP.

Introducción: la pandemia de COVID-19 impone a los profesionales de la salud: altas exigencias y modificaciones en el modo de vincularse con pacientes, pares y familiares. Estos cambios implican consecuencias emocionales tales como el incremento del nivel de estrés y síntomas de ansiedad y de depresión. Objetivo: describir un proyecto interdisciplinario creado bajo el modelo de la Medicina Narrativa dirigido a habilitar el relato de la experiencia de profesionales de la salud pertenecientes a un hospital general privado de alta complejidad de la ciudad de Buenos Aires durante la pandemia de COVID-19. Metodología: se creó una lista de correo y se convocó a profesionales del hospital a realizar una producción escrita, oral o gráfica que represente su experiencia durante la pandemia. Luego, el material recibido se envió a la misma lista de distribución con frecuencia semanal. En cada correo se renovó la invitación a narrar lo vivido o comentar los relatos de otros. Resultados: en el transcurso de siete semanas se recibieron diez producciones individuales: ocho textos, un audio y un gráfico. Los principales temas tratados pudieron agruparse en tres ejes: sala COVID, comunidad y telemedicina. Los autores fueron profesionales de Medicina, Enfermería, Psicología y de Puericultura. Conclusión: desarrollamos un proyecto bajo el modelo de la Medicina Narrativa que permitió a profesionales narrar su experiencia durante la pandemia de COVID-19, habilitando la posibilidad de poner en palabras lo vivido, reflexionar sobre modelos de actuación y elaborar el desgaste emocional generado por el contacto permanente con el dolor y el sufrimiento.

Introduction: the COVID-19 pandemic imposes high demands on health professionals and changes in the way they relate to patients, peers and family members. These changes involve emotional consequences such as increased stress levels, symptoms of anxiety and depression. Objective: to describe an interdisciplinary project created under the Narrative Medicine model aimed at enabling the reporting of the experience of health professionals belonging to a highly complex private general hospital in the city of Buenos Aires during the COVID-19 pandemic. Methodology: a mailing list was created and hospital professionals were invited to make a written, oral or graphic production that represents their experience during the pandemic. Then, the received material was sent to the same distribution list on a weekly basis. In each email, the invitation to narrate what was experienced or to comment on the stories of others was renewed. Results: over the course of seven weeks, ten individual productions were received: eight texts, one audio and one graphic. The main topics discussed could be grouped into three axes: COVID room, community and telemedicine. The authors were professionals from Medicine, Nursing, Psychology and Childcare. Conclusion: we developed a project under the Narrative Medicine model that allowed professionals to tell their experience during the covid 19 pandemic, enabling the possibility of putting into words what was experienced, reflecting on models of action and elaborating on the emotional exhaustion generated by permanent contact with pain and suffering.

Progressive heterotopic ossification (HO) is a hallmark of fibrodysplasia ossificans progressiva (FOP); however, this tissue transformation is not random. Rather, we noticed that HO in FOP progresses in well-defined but inexplicable spatial and temporal patterns that correlate precisely with infrared thermographs of the human body. FOP is caused by gain-of-function mutations in Activin A receptor type I (ACVR1/ALK2), a bone morphogenetic protein (BMP) type I receptor kinase. As with all enzymes, the activity of ACVR1 is temperature-dependent. We hypothesized that connective tissue progenitor cells that express the common heterozygous ACVR1R206H mutation (FOP CTPCs) exhibit a dysregulated temperature response compared to control CTPCs and that the temperature of FOP CTPCs that initiate and sustain HO at various anatomic sites determines, in part, the anatomic distribution of HO in FOP. We compared BMP pathway signaling at a range of physiologic temperatures in primary CTPCs isolated from FOP patients (n = 3) and unaffected controls (n = 3) and found that BMP pathway signaling and resultant chondrogenesis were amplified in FOP CTPCs compared to control CTPCs (p < 0.05). We conclude that the anatomic distribution of HO in FOP may be due, in part, to a dyregulated temperature response in FOP CTPCs that reflect anatomic location. While the association of temperature gradients with spatial patterns of HO in FOP does not demonstrate causality, our findings provide a paradigm for the physiologic basis of the anatomic distribution of HO in FOP and unveil a novel therapeutic target that might be exploited for this disabling condition.
