Project description:This review is describing the diagnostic and therapeutic approach to tracheobronchial involvement in relapsing polychondritis (RP), with a focus on differential diagnoses of inflammatory origin. RP is a systemic auto-immune disease that mainly affects cartilage structures, progressing through inflammatory flare-ups between phases of remission and ultimately leading to deformation of the involved cartilages. Besides the damage of auricular or nasal cartilage, tracheobronchial and cardiac involvement are the most severe, and can seriously alter the prognosis. Tracheobronchial lesions are assessed through a multimodal approach. Mapping of tracheal lesions is achieved using dynamic thoracic imaging and flexible bronchoscopy. Measurement of pulmonary function (with new emphasis on pulse oscillometry) is useful to diagnose obstructive ventilatory impairment, and can be used to follow RP patients, after therapeutics implementation. Diagnosis can be difficult in the absence of specific diagnostic tools, especially because there is a large number of differential diagnoses, in particular inflammatory diseases. Nuclear imaging can help with detection of metabolic activity on involved cartilages, leading to sharpen the final diagnosis. The prognosis has improved, thanks to the upgraded interventional bronchoscopy techniques, and the development of immunosuppressant including targeted therapies, such as tumor necrosis factor-α (TNF-α) inhibitors, offering patients several treatment options, in addition to supportive care.

Project description:BackgroundRelapsing polychondritis (RP) is a rare inflammatory disease characterized by recurrent inflammation and destruction of cartilaginous tissues. RP has characteristics of autoimmune disease and some reports have noted co-occurrence with autoimmune thyroid disease (AITD), consisting of Graves' disease (GD) and Hashimoto thyroiditis (HT). However, there have been no detailed studies on the co-occurrence of RP and AITD. In this study, we aimed to determine whether patients with RP tend to be complicated with AITD. We also analyzed the clinical and genetic profiles of patients in whom these diseases co-occur.MethodsWe recruited 117 patients with RP and reviewed their medical records. Furthermore, we genotyped Human Leucocyte Antigen (HLA)-A, B Cw, DRB1, DQB1, and DPB1 alleles for 93 of the 117 patients. The prevalence of AITD among the patients with RP was compared with that among the general Japanese population. We also analyzed the clinical and genetic features of the patients with both RP and AITD.ResultsThe prevalence of GD among the patients with RP was 4.3% (5 among 117 patients), significantly higher than that among Japanese (0.11%) (p = 2.44 × 10-7, binomial test). RP patients with GD tended to have nasal involvement (p = 0.023) (odds ratio (OR) 2.58) and HLA-DPB1*02:02 (p = 0.035, OR 10.41). We did not find significant enrichment of HT in patients with RP.ConclusionsPatients with RP appear to be at elevated risk of GD. Nasal involvement and HLA-DPB1*02:02 characterize the subset of RP patients with GD, which may guide attempts to characterize a distinct subtype of RP for precision medicine.

Project description:ObjectiveRelapsing polychondritis (RP) is a rare autoimmune inflammatory disease that attacks mainly cartilaginous structures or causes serious damage in proteoglycan-rich structures (the eyes, heart, blood vessels, inner ear). This study shows results regarding the epidemiology, progression, and associations of this highly variable disease by collecting all cases from a 124-million-person-year Central European nationwide cohort.MethodsWe used the Hungarian Health Care Database to identify all persons with possible RP infection. We followed patients who had International Classification of Diseases 10th edition code M94.1 at least once in their inpatient or outpatient records between January 1, 2002 and December 31, 2013 in Hungary. We classified these patients into disease severity groups by their drug consumption patterns between January 1, 2010 and December 31, 2013. We analyzed the regional distribution of RP incidences as well. Overall maps of comorbidity are presented with network layouts.ResultsWe identified 256 patients with RP among cumulatively 11.5 million registered inhabitants. We classified these patients into four severity classes as "extremely mild" (n=144), "mild" (n=22), "moderate" (n=41), and "severe" (n=4). Two additional groups were defined for patients without available drug data as "suspected only" (n=23) and "confirmed but unknown treatment" (n=22). The age and sex distributions of patients were similar to worldwide statistics. Indeed, the overall survival was good (95% confidence interval for 5 years was 83.6%-92.9% and for 10 years was 75.0%-88.3% which corresponds to the overall survival of the general population in Hungary), and the associations with other autoimmune disorders were high (56%) in Hungary. Almost any disease can occur with RP; however, the symptoms of chromosomal abnormalities are only incidental. Spondylosis can be a sign of the activation of RP, while Sjögren syndrome is the most frequent autoimmune association. Regional distribution of incidences suggests arsenic drinking water and sunlight exposure as possible triggering factors.ConclusionThe good survival rate of RP in Hungary is probably associated with the early diagnosis of the disease.

Project description:ObjectiveTo assess patient-reported burden of disease in pediatric patients with relapsing polychondritis (RP) and to compare those findings to adult patients.MethodsA survey based on known clinical symptoms of RP was developed and administered to patients with a pediatric diagnosis of RP. Adult patients completed a similar survey.ResultsTwenty-one pediatric patients, or their parents, completed surveys. Median age at symptom onset was 6 years (interquartile range 1.8-12). Prior to diagnosis, most pediatric patients went to the emergency room (ER; 61.9%), saw > 3 physicians (57.1%), and took > 1 year to be diagnosed (61.9%). Pediatric patients were often diagnosed with asthma (42.9%), ear infections (42.9%), or sinusitis (33.3%) prior to diagnosis of RP. Symptoms prior to diagnosis included ear pain/redness (85.7%), joint pain/swelling (61.9%), and airway symptoms (38.1%). Four pediatric patients (19%) reported tracheomalacia requiring tracheostomy. Pediatric patients frequently missed school because of their disease (71.4%). Surveys from 290 adult patients were compared to pediatric patients. Pediatric patients were significantly more likely to undergo biopsy (42.9% vs 17.4%; p < 0.01) and be treated with biologics (42.9% vs 19%; p = 0.02). Adults were significantly more likely to be female (87.8% vs 28.6%; p < 0.01) and to report airway symptoms (77.9% vs 47.6%; p = 0.01). Prevalence of disease complications was not significantly different between adult and pediatric patients.ConclusionsThe burden of disease in pediatric patients with RP includes missed school, diagnostic delay, ER visits, and multisystem disease, with resultant damage to cartilaginous structures. Differences in airway involvement and treatment approaches may exist between pediatric and adult patients.

Project description:Relapsing polychondritis (RP) is a rare autoimmune disorder, characterized by the inflammation of cartilaginous structures and proteoglycan-rich tissues. Due to its rarity and the notoriously variable presentations, the diagnosis of RP could be challenging. We report an unusual case of RP with isolated tracheal involvement and very non-specific symptoms of exertional dyspnoea and dry cough. The initial chest radiograph showed long-segment narrowing of the trachea, and the computed tomography of the chest revealed thickened cartilaginous walls of the trachea, while the posterior membranous portion was spared. The tracheal narrowing was readily observed under bronchoscopy. The patient was treated with oral prednisolone. Although the subsequent course was transiently complicated by an episode of severe Pneumocystis jirovecii pneumonia with acute respiratory distress syndrome, the patient overall responded well to systemic corticosteroid therapy. No new symptoms developed during a two-year follow-up.

Project description:ObjectivesRelapsing polychondritis (RP) is a rare, heterogeneous, systemic inflammatory disease that targets cartilage. Patient-reported outcome measures may differ from physician assessment. This study compared patient global assessment (PtGA) and physician global assessment (PhGA) scores in a prospective cohort of patients with RP.MethodsAdult patients with RP underwent a standardized comprehensive evaluation at ∼6 month intervals. At each visit, three physicians scored PhGA by consensus. The patient independently completed four patient-reported outcomes: PtGA, 36-item Short Form Health Survey (SF-36), Brief Illness Perception Questionnaire (BIPQ) and Multidimensional Fatigue Inventory (MFI). Patient-physician discordance was defined as a difference between PtGA and PhGA of ≥3 on a 0-10 scale.ResultsA total of 76 patients were evaluated over 154 visits. The median PhGA was 3 [interquartile range (IQR) 2-3] and the median PtGA was 5 (IQR 4-7). PtGA and PhGA were concordant in 66 visits (42.9%) and patients scored disease severity ≥3 points higher than physicians scored disease activity (positive discordance) in 84 visits (54.5%). Compared with visits with concordance, visits with positive discordance were associated with significantly worse scores on the MFI, BIPQ, SF-36 physical component score and SF-36 mental component score.ConclusionPatients with RP typically self-report high PtGA that does not align with PhGA. Discordance is likely driven by the high physical and psychological burden of illness experienced by patients. Multifaceted treatment approaches that address the burden of disease in RP from the patient perspective are needed.

Project description:BackgroundCommonly clinically diagnosed with relapsing polychondritis (RP), vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic syndrome (VEXAS) is a recently identified autoinflammatory disease caused by UBA1 somatic mutations. The low frequency and dynamic changes challenge the accurate detection of somatic mutations. The present study monitored these mutations in Chinese patients with RP. We included 44 patients with RP. Sanger sequencing of UBA1 was performed using genomic DNA from peripheral blood. Droplet digital polymerase chain reaction (ddPCR) was performed to screen low-prevalence somatic variants.ResultsMultiple ddPCR detections were performed using available blood samples collected at different follow-up time points. Three male patients were UBA1 somatic mutation carriers. Sanger sequencing detected the somatic UBA1 variant c.122T > C (p.Met41Thr) in two male patients. Initial ddPCR confirmed the variant in the two patients, with allele fractions of 73.75% and 88.46%, respectively, while yielding negative results in other patients. Subsequent ddPCR detected the somatic variant (c.122T > C) with low prevalence (1.02%) in another male patient from blood samples collected at a different time point, and confirmed dynamically fractional abundance in one patient with VEXAS, with allele fractions of 73.75%, 61.28%, 65.01%, and 73.75%. Nine patients assessed by ddPCR at different time points remained negative.ConclusionWe report UBA1 variants in patients with RP in the Chinese population for the first time. Multiple ddPCR detections from samples collected at different time points can enhance sensitivity and should be considered for patients with initial negative ddPCR results.

Project description:Airway involvement in relapsing polychondritis (RP) can be debilitating and life threatening, often requiring interventional procedures. If standard therapies including systemic corticosteroid and immunosuppressive agents are ineffective, airway stenting is often required. Recently, biologics have been reported to be effective for RP, and the early administration of biologics may avoid airway stenting. To evaluate survival rates and treatment approaches, medical records of RP patients with airway involvement were reviewed. These cases were divided into the following groups: with and without malacia, stenting and non-stenting, and with and without biologics. Kaplan-Meier was used to calculate survival rates and log rank tests were used to analyze biologics groups. A total of 77 patients were enrolled. Airway stenting was performed in 13 patients, all of which developed airway malacia. The stenting group had significantly lower survival rates than the non-stenting group (p < 0.001). Stent-related complications were granulation tissue (85%) and mucostasis (69%). In the non-stenting group, a lower mortality rate was observed. A significantly higher survival rate was seen in patients administered biologics than without (p = 0.014). The early administration of biologics shows promise in preventing severe airway disorders that require airway stenting.

Project description:ObjectiveTo assess patient-reported symptoms and burden of disease in relapsing polychondritis (RP).MethodsPatients with RP completed a disease-specific online survey to identify symptoms attributed to illness. Patients were divided into subgroups based upon presence or absence of ear/nose, airway, or joint involvement. Pathway to diagnosis, treatment, and disease-related complications were assessed within each subgroup.ResultsData from 304 respondents were included in this analysis. Prior to diagnosis, most patients with RP went to the emergency room (54%), saw > 3 physicians (54%), and had symptoms for >5 years (64%). A concomitant diagnosis of fibromyalgia and absence of ear/nose or joint involvement was associated with diagnostic delay >1 year. Common diagnoses prior to RP diagnosis included asthma in patients with airway involvement (35% versus 22%; P = 0.03) and ear infection in patients with ear/nose involvement (51% versus 6%; P < 0.01). Patients with joint involvement were more likely to receive a glucocorticoid-sparing agent (85% versus 13%; P < 0.01). Most patients reported a major complication, including disability (25%), tracheomalacia (16%), or hearing loss (34%). Patients with airway involvement reported more tracheomalacia (20% versus 4%; P < 0.01). Disability (24% versus 7%; P < 0.01) and hearing loss (39% versus 11%; P < 0.01) were prevalent in the joint involvement subgroup.ConclusionPatient-reported data in RP highlight a significant burden of disease. Patterns of organ involvement may lead to diagnostic delay and influence treatment decisions, ultimately impacting the development of disease-related complications. Timely diagnosis, standardization of treatment approaches, and prevention of disease-related complications are major unmet needs in RP.
