Limited auricular relapsing polychondritis in a child treated successfully with infliximab

Relapsing polychondritis in childhood: A case report

RATIONALE

Relapsing polychondritis (RP) is a rare immune-mediated disease that leads to progressive cartilage destruction, notably affecting the ears, nose, and airways. Timely diagnosis is essential to prevent irreversible airway damage and life-threatening complications. This study presents a case of a 12-year-old child diagnosed with RP, emphasizing the critical need for timely identification of RP in children.

PATIENT CONCERNS

A 12-year-old girl was admitted with worsening hoarseness and cough, leading to respiratory distress and severe bradycardia, requiring transfer to the pediatric intensive care unit. After successful resuscitation and tracheal intubation, imaging showed significant subglottic swelling. She received antibiotics, corticosteroids, and nebulization. Despite initial stabilization, she required a tracheostomy 2 months post-discharge due to recurrent dyspnea. Six months later, she developed joint pain and a saddle nose deformity.

DIAGNOSES

The patient was clinically diagnosed with RP in accordance with the diagnostic standards set forth by Micheet et al.

INTERVENTIONS

During the initial phase of treatment, the patient was administered antibiotics, corticosteroids, and nebulization therapy. Due to severe respiratory distress, an emergency tracheostomy was performed by ear, nose, and throat surgeons. After a definitive diagnosis, the patient was treated with tocilizumab, methotrexate, and corticosteroid therapy. Additionally, supportive measures including calcium supplementation, gastric protection, and immune support were provided.

OUTCOMES

Three years post-diagnosis, the patient's condition is stable.

LESSONS

Due to RP low prevalence, diagnosis in children is frequently delayed or overlooked. Notably, involvement of the major airways is more common and severe in pediatric patients compared to adults. It is crucial for Otolaryngologists to have a comprehensive understanding of this condition to effectively diagnose and manage complications associated with RP.

Clinical patterns and the evolution of relapsing polychondritis based on organ involvement: a Chinese retrospective cohort study

Background

Relapsing polychondritis (RPC) is a rare autoimmune disease and its early diagnosis remains challenging. Defining the clinical patterns and disease course may help early recognition of RPC.

Results

Sixty-six males and 60 females were included in this study. The average age at onset were 47.1 ± 13.8 years and the median follow-up period was 18 months. Correlation analysis revealed a strong negative correlation between airway involvement and auricular chondritis (r = − 0.75, P < 0.001). Four distinct clinical patterns were identified: Ear pattern (50.8%), Airway pattern (38.9%), Overlap pattern (4.8%) and Airway-Ear negative pattern (5.6%), and patients with Ear pattern and Airway pattern were further divided into limited and systemic form of RPC (27.8% with limited form of Ear pattern and 24.6% with limited form of Airway pattern initially). During follow-up, a minority of patients with Ear pattern and Airway pattern progressed into Overlap pattern, and some Airway-Ear negative pattern patients progressed into Ear pattern. While a large majority of limited RPC patients remained limited form during follow-up, a minority of limited RPC patients progressed into systemic form. Patients with Ear pattern had the highest survival rate and relatively lower inflammatory status.

Conclusions

RPC patients can be categorized as 4 different clinical patterns and 2 distinct presenting forms (limited and systemic) based on organ involvement. The clinical patterns and presenting forms may evolve during follow-up. Our findings may facilitate early recognition of this rare disease.

Relapsing polychondritis: an unusual cause of sore throat, painful ear swelling and bilateral costal margin pain

A 54-year-old Chinese woman presented with a 3-month history of sore throat and dry cough, which was treated as chronic pharyngitis with minimal improvement. One month ago, she presented with painful right ear swelling without signs or symptoms of otitis media or otitis externa. She was treated with antibiotics and antiviral drugs without any improvement. Two weeks prior to her presentation to hospital, she developed bilateral costal margin pain with raised C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), mild chronic pharyngitis and painful right ear swelling. All other investigations including bloods and imaging were non-specific. Her painful right auricle swelling prompted the diagnosis of relapsing polychondritis (RP), which was supported by clinical improvement with high-dose corticosteroids. RP is a clinical diagnosis with non-specific inflammation of affected cartilage. It is a diagnosis of exclusion and early diagnosis can be made by the most common presenting feature of auricular chondritis.

Treatment of auricular relapsing polychondritis in a Saudi child using only non-steroidal anti-inflammatory drugs: a case report

Relapsing polychondritis (RP) is an autoimmune disease that can involve multiple sites within the human body. It is characterized by recurrent bouts of painful cartilage inflammation, and it can cause severe complications if it affects the vital organs. This report describes the case of a five-year-old child with limited auricular RP. The patient's history was obtained from his family, and a physical examination was performed at a pediatric rheumatology clinic. The patient was successfully treated using only a non-steroidal anti-inflammatory drug, and he completely recovered. This treatment and recovery have not been reported in the literature. Therefore, these results are worthy of mention in order to avoid the use of immunosuppressant medications with localized involvement.

Relapsing polychondritis in children: A review

Relapsing polychondritis (RP) is a rare auto-immune disease that causes progressive destruction of cartilaginous structures. Most cases of pediatric-onset RP were published as a single case report or hand-full case series although the prevalence of RP is unknown. This review aimed to describe the characteristics of pediatric-onset RP in order to provide a comparison between childhood and adulthood features of the disease and to review the experiences of biological agents used in children with RP. In children, the diagnosis of RP is either delayed or overlooked due to low incidence and variability in clinical features. Treatment of RP is challenging due to the recurrent episodic nature of the disease. Different immunosuppressive medications, including steroid and steroid-sparing disease-modifying antirheumatic drugs (DMARDs), such as methotrexate or azathioprine, are used to treat RP. There is no rigorous clinical research to support the use of new therapeutic modalities, including biological agents. It is challenging to protocolize the treatment of pediatric-onset RP due to the rarity of the disease. Corticosteroids are the primary form of therapy. However, DMARDs and biological agents may have a role in treating patients with sustained or refractory disease.
