Unveiling the clinical spectrum of relapsing polychondritis: insights into its pathogenesis, novel monogenic causes, and therapeutic strategies

Abstract Relapsing polychondritis is a rare multisystem disease involving cartilaginous and proteoglycan-rich structures. The diagnosis of this disease is mainly suggested by the presence of flares of inflammation of the cartilage, particularly in the ears, nose or respiratory tract, and more rarely, in the presence of other manifestations. The spectrum of clinical presentations may vary from intermittent episodes of painful and often disfiguring auricular and nasal chondritis to an occasional organ or even life-threatening manifestations such as lower airway collapse. There is a lack of awareness about this disease is mainly due to its rarity. In 2020, VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome, a novel autoinflammatory syndrome, was described. VEXAS syndrome is attributed to somatic mutations in methionine-41 of UBA1, the major E1 enzyme that initiates ubiquitylation. This new disease entity connects seemingly unrelated conditions: systemic inflammatory syndromes (relapsing chondritis, Sweet's syndrome, and neutrophilic dermatosis) and hematologic disorders (myelodysplastic syndrome or multiple myeloma). Therefore, this article reviews the current literature on both disease entities.

A 31-year-old female patient is presented, with a history of menstrual disorders, arterial hypertension, diabetes mellitus, and collagenosis in the family. Which presents a clinical picture that evolves from joint pain to nasal, auricular and tracheal chondritis, as well as vestibulocochlear alterations, which lead to the diagnosis of relapsing polychondritis. Nowadays has a permanent tracheostomy and is responding favorably to treatment.

Policondritis recidivante: manifestaciones clínicas y tratamiento / Recurrent polychondritis. Clinical, diagnosis and treatment

La policondritis recidivante es una enfermedad rara caracterizada por la inflamación recurrente del cartílago y otros tejidos en todo el cuerpo. La afectación del oído es la característica más común, pero puede afectar otras áreas del cuerpo, incluidos el cartílago costal, los ojos, la nariz, las vías respiratorias, el corazón, el sistema vascular, la piel, las articulaciones, los riñones y el sistema nervioso. Los signos y síntomas varían de persona a persona según las partes del cuerpo afectadas. La causa subyacente exacta de la policondritis recidivante se desconoce, aunque los científicos sospechan que se trata de una enfermedad autoinmune. Las complicaciones respiratorias (colapso de la tráquea e infecciones) son la causa más común de muerte, seguidas de la afectación cardiovascular. Los objetivos principales del tratamiento son aliviar los síntomas actuales y preservar la estructura del cartílago afectado. Gracias a las mejoras en el tratamiento, en los últimos años las tasas de supervivencia han aumentado, incluso después de 10 años(AU)

Recurrent polychondritis is a rare condition characterized by recurrent inflammation of cartilage and other tissues throughout the body. Ear involvement is the most common feature, but a variety of other areas of the body may be compromised, including costal cartilage, eyes, nose, airways, heart, vascular system, skin, joints, kidneys and nervous system. The signs and symptoms vary from person to person depending on the body parts affected. The exact underlying cause of recurrent polychondritis is unknown; however, scientists suspect it is an autoimmune condition. The main goals of treatment for people with recurrent polychondritis are to alleviate current symptoms and preserve the structure of the affected cartilage(AU)

Policondritis recidivante como fenómeno paraneoplásico en paciente con síndrome mielodisplásico / Relapsing Polychondritis as paraneoplastic phenomenon in patient with Myelodysplastic Syndrome

Los síndromes mielodisplásicos son un grupo heterogéneo de enfermedades hematológicas, caracterizadas por hematopoyesis ineficaz con riesgo de progresión a leucemia mieloide aguda. Pueden asociarse a manifestaciones autoinmunes en un 10-30% de los pacientes, apareciendo antes, durante o luego del diagnóstico del trastorno hematológico. La prevalencia de policondritis recidivante como fenómeno paraneoplásico es de 0,7-5,4%, presentándose de forma simultánea en la mayoría de los casos. Otros procesos autoinmunes asociados incluyen: vasculitis sistémica, poliartritis seronegativa, dermatosis neutrofílica, citopenias inmunomediadas, presencia de autoanticuerpos y crioglobulinemia. Reportamos el caso de una mujer de 60 años, sin antecedentes patológicos previos, que presentó un cuadro de policondritis recidivante y vasculitis sistémica asociadas a síndrome mielodisplásico.

Myelodysplastic syndromes are a heterogeneous group of hematological diseases, characterized by ineffective hematopoiesis with risk of progression to acute myeloid leukemia. They can be associated to autoimmune manifestations in 10-30% of patients, appearing before, during or after the diagnosis of the hematological disorder. The prevalence of relapsing polychondritis as a paraneoplastic phenomenon is 0.7-5.4%, occurring simultaneously in the majority of cases. Other associated autoimmune processes include: systemic vasculitis, seronegative polyarthritis, neutrophilic dermatosis, immunomediated cytopenias, presence of autoantibodies and cryoglobulinemia. We report the case of a 60-year-old woman, with no previous medical history, who presented with recurrent polychondritis and systemic vasculitis associated with myelodysplasia.

Relapsing polychondritis, a rare cause of valvulopathy: A review of the medical literature / Policondritis recurrente, una rara causa de valvulopatía: revisión de las publicaciones médicas

Abstract Relapsing polychondritis (RP) is an inflammatory disease that involves cartilaginous structures predominantly in the nose, ears, and respiratory tract. Cardiovascular involvement is not common. Despite this, they are the second cause of death in patients with RP. The structures usually affected by this disease are the heart valves, with regurgitation being the most common valvulopathy. We present the case of a patient without the previous diagnosis of RP who was referred to our institute with heart failure secondary to aortic regurgitation, initially attributed to endocarditis.

Resumen La policondritis recurrente (PR) es una enfermedad inflamatoria que afecta a estructuras cartilaginosas, predominantemente las que se encuentran en nariz, pabellones auriculares y vías respiratorias. Las manifestaciones cardiovasculares son poco comunes; sin embargo, son la segunda causa de mortalidad en pacientes con PR. Unas de las estructuras afectadas casi siempre en la PR son las estructuras valvulares y la valvulopatía más común es la insuficiencia aórtica (IA). A continuación se presenta el caso de una paciente sin diagnóstico previo de PR a quien se refirió a este instituto por insuficiencia cardíaca secundaria a IA, atribuida en un principio a endocarditis.

Policondritis recidivante asociada a enfermedad por IgG4 / Relapsing polychondritis associated with IgG4-related disease

La policondritis recidivante (RP) es un trastorno autoinmune sistémico poco frecuente que se caracteriza por episodio y deterioro progresivo de la inflamación del cartílago. Aproximadamente el 30% de los pacientes con RP tienen enfermedad concurrente. Sin embargo, hay tres casos previos reportados de RP relacionado con enfermedad relacionada con la inmunoglobulina G4 (IgG4-RD). Nosotros presentamos otro caso de una mujer de 37 años que desarrolló RP aproximadamente 1 año antes del diagnóstico de IgG4-RD. La asociación entre ER-IgG4 y RP sigue sin estar clara.

Relapsing polychondritis (RP) is a rare systemic autoimmune disorder characterized by the episodic and progressive deterioration of cartilage inflammation. Approximately 30% patients with RP have concurrent disease. However, there are three cases reports of RP complicated by immunoglobulin G4-related disease (IgG4-RD). Here we report another case of a 37-year-old female who developed RP approximately 1 years before IgG4-RD diagnosis. The association between IgG4-RD and RP remains unclear.

Clinical Features of Relapsing Polychondritis Patients Presented with Arthropathy / 中国医学科学院学报

Objective To explore the clinical characteristics of relapsing polychondritis(RP)patients presented with arthropathy. Methods We retrospectively analyzed the clinical data of 201 RP patients who were hospitalized in our center between December 2005 and February 2019.After 16 patients with co-existing other autoimmune diseases and malignancies were ruled out,185 RP patients entered the final analysis,among whom 16 RP patients were presented with arthropathy and 169 without arthropathy.The demographic data,clinical manifestations,laboratory findings,and prognosis were compared between these two groups. Results Five of the 16 RP patients with arthropathy at presentation were misdiagnosed as rheumatoid arthritis.Compared with RP patients without arthropathy at presentation,RP patients with arthropathy at presentation had a longer disease course[(37.50±66.50)months

Relapsing polychondritis: prevalence of cardiovascular diseases and its risk factors, and general disease features according to gender / Policondrite recidivante: prevalência de doenças cardiovasculares e seus fatores de risco e características gerais da doença de acordo com o gênero

ABSTRACT The comorbidities in relapsing polychondritis have been scarcely described in the literature. Moreover, apart from a few relapsing polychondritis epidemiological studies, no studies specifically addressing relapsing polychondritis distribution according to gender are available. Therefore, the objectives of the present study were: (a) to analyze the prevalence of cardiovascular diseases and its risk factors in a series of patients with relapsing polychondritis; (b) to determine the influence of gender on relapsing polychondritis. A cross-sectional tertiary single center study evaluating 30 relapsing polychondritis cases from 1990 to 2016 was carried out. To compare comorbidities, 60 healthy individuals matched for age-, gender-, ethnicity- and body mass index were recruited. The mean age of relapsing polychondritis patients was 49.0 ± 12.4 years, the median disease duration 6.0 years, and 70% were women. A higher frequency of arterial hypertension (53.3% vs. 23.3%; p = 0.008) and diabetes mellitus (16.7% vs. 3.3%; p = 0.039) was found in the relapsing polychondritis group, compared to the control group. As an additional analysis, patients were compared according to gender distribution (9 men vs. 21 women). The clinical disease onset features were comparable in both genders. However, over the follow-up period, male patients had a greater prevalence of hearing loss, vestibular disorder and uveitis events, and also received more cyclophosphamide therapy (p < 0.05). There was a high prevalence of arterial hypertension and diabetes mellitus, and the male patients seemed to have worse prognosis than the female patients in the follow up.

RESUMO Há escassez de estudos na literatura sobre as comorbidades na policondrite recidivante (PR). Além disso, exceto por alguns estudos epidemiológicos sobre a PR, não existem trabalhos que analisem especificamente a distribuição da PR de acordo com o gênero. Portanto, os objetivos do presente estudo foram: (a) analisar a prevalência de doenças cardiovasculares e seus fatores de risco em uma série de pacientes com PR; (B) determinar a influência do gênero na PR. Fez-se um estudo transversal unicêntrico que avaliou 30 casos de PR entre 1990 e 2016. Para comparar as comorbidades, foram recrutados 60 indivíduos saudáveis pareados por idade, gênero, etnia e índice de massa corporal. A idade média dos pacientes com PR foi de 49,0 ± 12,4 anos. A duração média da doença foi de 6,0 anos e 70% eram mulheres. Foi observada uma maior frequência de hipertensão arterial (53,3% vs. 23,3%, p = 0,008) e diabetes mellitus (16,7% vs. 3,3%; p = 0,039) no grupo PR em comparação com o grupo controle. Em uma análise adicional, os pacientes foram comparados de acordo com a distribuição de gênero (nove homens versus 21 mulheres). As características clínicas iniciais da doença foram comparáveis em ambos os sexos. No entanto, durante o período de seguimento, os pacientes do sexo masculino tiveram maior prevalência de perda auditiva, envolvimento vestibular e eventos de uveíte e também receberam mais tratamento com ciclofosfamida (p < 0,05). Houve uma alta prevalência de hipertensão arterial e diabetes mellitus e os pacientes do sexo masculino apresentaram pior prognóstico do que as pacientes do sexo feminino no seguimento.

Relapsing polychondritis in Singapore: a case series and review of literature

<p><b>INTRODUCTION</b>This study aimed to describe the clinical presentation, treatment and outcome of patients with relapsing polychondritis (RP) who were seen at a large tertiary-care academic medical institution in Singapore.</p><p><b>METHODS</b>The medical records of all patients diagnosed with RP at the Department of Rheumatology and Immunology, Singapore General Hospital, Singapore, between 2005 and 2013 were reviewed. The diagnosis of RP was made using the modified McAdam criteria.</p><p><b>RESULTS</b>Ten patients were diagnosed with RP during the study period. Among these patients, five fulfilled the modified McAdam criteria and five were probable cases of RP. The most common clinical presentations were auricular chondritis (n = 9), episcleritis or scleritis (n = 5), and large airway involvement (n = 3). All of the patients received prednisolone. Five patients developed haematological disorders. Patients with both RP and haematological disorders had a longer duration of RP symptoms prior to diagnosis, compared to patients with RP who did not develop haematological disorders (average duration of symptoms 14.7 months vs. 4.2 months).</p><p><b>CONCLUSION</b>The high frequency of patients with haematological malignancies in this series was unexpected. Myelodysplastic syndrome has been reported, but other haematological malignancies are rarely associated with RP. As the association between haematological malignancies and RP is currently unclear, the threshold for haematological/lymphoproliferative screening should be lowered in patients with RP.</p>

Relapsing Polychondritis Presented with Encephalitis Followed by Brain Atrophy

Relapsing polychondritis (RP) is a rare autoimmune disease that is characterized by inflammatory reaction of unknown etiology and destruction of cartilaginous structures. Characteristic symptoms of this disease include cartilage inflammation of the ear, nose, larynx, trachea, bronchi, joints, eyes, heart and skin. Concomitance with neurologic symptom is very rare in RP, and the detailed underlying mechanism of neurological involvement associated with RP is not fully understood. We herein described an unusual recurrent case of inflammatory brain lesions associated with RP, with attention to clinical manifestations, autoimmune disease involvement, and therapeutic effects.

Policondritis recidivante / Relapsing polychondritis

La policondritis recidivante, es una infrecuente enfermedad inflamatoria del tejido conjuntivo, de etiología desconocida. Se caracteriza por inflamación episódica y progresiva de tejido cartilaginoso, principalmente del pabellón auricular, nariz y árbol traqueo-bronquial. Se presenta el caso de una paciente femenina de 58 años, que consulta por enrojecimiento y dolor en pabellón auricular derecho, con episodios previos similares en ambos oídos y nariz, además de estudio por poliartritis simétrica. Al examen físico destaca: eritema, edema y dolor local en pabellón auricular, respetando lóbulo. Con exámenes complementarios normales y presencia de tres criterios característicos de McAdam, se diagnostica policondritis recividante, iniciando prednisona oral, con respuesta favorable. Pese a ser una enfermedad poco frecuente, es importante considerarla en casos recurrentes de eritema y dolor local en regiones cartilaginosas, principalmente en pabellón auricular y nariz, de tal forma de lograr un diagnóstico precoz, para suprimir las crisis y mejorar el pronóstico de estos pacientes.

Relapsing Polychondritis (RP) is a rare inflammatory connective tissue disease of unknown etiology. It is characterized by episodic and progressive inflammation of cartilage tissue, especially ear, nose and tracheobronchial tree. We report the case of 58 year old Chilean female patient, who consulted for redness and pain in the right ear, with similar previous episodes in both ears and nose; along with symmetric polyarthritis study it is presented. Physical examination highlighted erythema, edema and local pain in ear, respecting lobe. With normal complementary examinations and presence of three diagnostic criteria of McAdam y col. relapsing polychondritis diagnosed, initiating oral prednisone, with favorable response. Despite being a rare disease, it is important to consider in recurrent cases of erythema and local pain in cartilaginous regions, mainly in ear and nose, so to achieve early diagnosis, to suppress the crisis and improve the prognosis of these patients.

Relapsing Polychondritis Showing Personality Changes and Cognitive Impairment / 계명의대학술지

Relapsing polychondritis is a rare, multisystem autoimmune disease. It is characterized by recurrent inflammation of the cartilage and connective tissues in the body. In this paper, we described a case of relapsing polychondritis initially presented symptoms of cognitive dysfunction and personality changes. A 63-year-old male reprented fever, cognitive impairment and personality changes. Brain magnetic resonance imaging revealed leptomeningeal and periauricular hyperintensities. A cerebrospinal fluid examination showed aseptic meningitis. As he reprented hearing difficulties, audiometry showed the sensory neural hearing loss. On physical examination, erythematous swollen auricles were noted. Auricle biopsy consisted with inflammation with perichondritis. He was diagnosed with relapsing polychondritis accompanied by leptomeningeal meningitis, and treated with methylprednisolone (62.5 mg/day for 3 days) followed by prednisolone 60 mg/day and methotrexate 7.5 mg/week. Fever and painful swellings on the both ears subsided. He showed improvement in cognitive function and personality. Although relapsing polychondritis is rare, it should be considered to be a possible cause of leptomeningeal meningitis.

Relapsing Polychondritis with Central Nervous System Involvement: Experience of Three Different Cases in a Single Center

Relapsing polychondritis (RP) is an autoimmune disorder characterized by inflammation in cartilaginous structures including the ears, noses, peripheral joints, and tracheobronchial tree. It rarely involves the central nervous system (CNS) but diagnosis of CNS complication of RP is challenging because it can present with varying clinical features. Herein we report 3 cases of relapsing polychondritis involving CNS with distinct manifestations and clinical courses. The first patient presented with rhombencephalitis resulting in brain edema and death. The second patient had acute cognitive dysfunction due to limbic encephalitis. He was treated with steroid pulse therapy and recovered without sequelae. The third patient suffered aseptic meningitis that presented as dementia, which was refractory to steroid and immune suppressive agents. We also reviewed literature on CNS complications of RP.

Relapsing Polychondritis: A Case Report.

Relapsing polychondritis is a chronic, recurrent, episodic, inflammatory disease of unknown cause affecting predominantly the cartilaginous tissues of the body. Episodes last few days to weeks. All types of cartilages may be involved. The most common presentation is the involvement of pinnae cartilages. The term was coined by Pearson and was first described by Jacksch-Wartenhorst in 1923, who called it polychondropathies. Annual incidence is about 3.5/million with the peak age at onset ranging from 40 to 50 years. Autoimmune etiology is suspected. Diagnosis is based on McAdam et al., criterion. Corticosteroid remains the mainstay of treatment along with the anti-inflammatory drugs. Here we present a case of 18-year-old male who presented with the involvement of the laryngeal cartilages, which is a rare presentation and later there was an involvement of other cartilages too. Our patient had four of McAdams criteria and also responded to steroids.

A Case of Relapsing Polychondritis Presenting with Diffuse Tracheobronchial Involvement

Relapsing polychondritis is a rare autoimmune disease involving the cartilaginous structures of the whole body. Its diagnosis can be difficult when the typical clinical features such as auricular chondritis are absent. Here, we report on a case of a 51-year-old female who presented with cough, dyspnea, and polyarthritis. Chest computed tomography showed the diffuse involvement of tracheobronchial cartilage. According to Damiani's criteria, she was diagnosed as relapsing polychondritis even though there was no unique involvement of auricular cartilage, and high dose steroid and immunosuppressive therapy were then started. This case indicated that patients who have tracheobronchial cartilage involvement without definite auricular chondritis should be considered for relapsing polychondritis as a differential diagnosis.

A Case of Relapsing Polychondritis Associated with Ankylosing Spondylitis

Relapsing polychondritis is an uncommon disease associated with inflammation in cartilaginous tissues throughout the body, particularly affecting the cartilaginous structures of ears, nose, joints, and respiratory tract. Several autoimmune diseases, including vasculitis, are associated with the concurrent relapsing polychondritis. However, ankylosing spondylitis primarily affecting the sacroiliac joints and spine is rare in patients with relapsing polychondritis. We report on a 54-year-old man with concurrently relapsing polychondritis and ankylosing spondylitis.

Clinical manifestation of child-onset relapsing polychondritis / 中华风湿病学杂志

Objective To investigate the clinical features of child-onset relapsing polychondritis (CORP). Methods The clinical manifestations of 11 CORP cases were analyzed retrospectively. Results Eleven cases of CORP were collected with Male to Female ratio of 5 ∶6; the mean age of disease onset was (11±4)(3-15) years; and the mean age of final diagnosis was(16±5)(6-22) years-old. The mean time of delay of diagnosis was(55±46)(2-144) month. Nine cases were simple CORP and 2 cases were concurred with SLE and pSS respectively. Laryngotracheal symptoms as initial presentation was seen in 7/11(64%) of cases, followed by rhinitis, eye involvement and arthritis. Laryngotracheal involvement occurred in 10/11 (91%) cases and 6/11(55%) underwent trachectomy when the diagnosis was made, followed by eye and nose involvement (saddle nose)(46% each), involvement of auricular cartilage,vestibule disorder and arthritis (36% each). Elevation of ESR or CRP(36%) were observed and positive autoantibody(18%) were detected in serology study; 9/11 (82%) were treated with steroid combined immunosuppressant. All cases were improvedor stable except 2 cases with exacerbation after upper respiratory infection during the follow-up of mean(27±15)(4-48) month. Conclusion Laryngopharyngeal involvement is the most common phenomenon in CORP and is associated with poor prognosis due to diagnosis delay. Imaging investigation may provide useful evidence for early diagnosis. Aggressive treatment is helpful in improving outcome.

A Case of Relapsing Polychondritis with Sequentially Bilateral Sudden Sensory Neural Hearing Loss / 대한이비인후과학회지

Relapsing polychondritis is a relatively rare systemic disease of unknown etiology. The disease is considered as an autoimmune disorder and characterized by episodic recurrent inflammation of cartilage and connective tissue, most often of the ears, nose, eyes, joints, respiratory tract, cardiovascular system and audiovestibular system. Treatment plans involve suppression of the immune system with corticosteroid. However, steroid therapy is associated with a number of adverse effects, and non-steroidal anti-inflammatory agents and immunosuppressive agents are helpful in treating the disease. Authors have recently experienced a case of relapsing polychondritis in a 24-year-old man who had both auricular chondritis and bilateral sudden hearing loss with vertigo. The patient showed a significant hearing improvement with the treatment using steroid and immunosuppressive agents. We report this case with a review of the literature.

Aggravation of Relapsing Polychondritis due to the Infection and Its Manifestation on a Nasal Tip Graft

Relapsing polychondritis (RP) is an uncommon systemic disease that is characterized by episodic and progressive inflammation of the cartilaginous structures, which can be very debilitating and in some instances life-threatening. The pathogenic pathways of RP are largely unknown. However, several hypothesis have been suggested. We had an interesting case of aggravation of RP due to the infection. Graft cartilage on the nasal tip was affected by RP also. This case can give a clue of revealing the pathogenesis of RP. We introduce a case with a review of the literature.
