Relapsing polychondritis: a clinical review

Annular eruption preceding relapsing polychondritis: case report and review of the literature

Relapsing polychondritis (RP) is a rare multisystem disorder affecting cartilaginous tissues, primarily of the ears, nose, larynx, and trachea. RP shows dermatologic manifestations in 35-50% of cases, and may show skin findings as the first sign of disease in 12% of affected patients. There have been reports of urticarial-like lesions in RP, typically associated with vasculitis, as well as a few reports of erythema multiforme-like lesions. There has also been one previous report of erythema annulare centrifugum associated with RP, presenting with a histology suggestive of a drug eruption. Our patient presented with urticarial and erythema annulare centrifugum-like plaques preceding the diagnosis of RP by over 1 year, with an initial histology suggestive of a drug eruption.

Relapsing polychondritis: an uncommon cause of dementia

Relapsing polychondritis Is a rare disorder that is characterised by recurrent and progressive inflammation of cartilaginous structures. Nervous system involvement in relapsing polychondritis has been described. We describe two cases of relapsing polychondritis with subacute dementia.

Aseptic meningitis with relapsing polychondritis mimicking bacterial meningitis

Relapsing polychondritis (RP) is a rare multisystem autoimmune disease. Though meningitis in RP is not common, some cases with cerebrospinal fluid (CSF) pleocytosis of the lymphocyte cells have been reported. Of the 18 previously reported cases, two cases demonstrated pleocytosis of polymorphonuclear leukocytes (PMN) in the CSF. In addition, cases with a decreased glucose level in the CSF were also seen. Our case also demonstrated pleocytosis of PMN in CSF mimicking bacterial meningitis. In the clinical field, as it is not possible to obtain a culture of CSF on admission day, the glucose level and cellular fraction are considered important. Therefore, meningitis in RP should be considered as a differential diagnosis of bacterial meningitis.

HLA class II transgenic mice mimic human inflammatory diseases

Population studies have shown that among all the genetic factors linked with autoimmune disease development, MHC class II genes on chromosome 6 accounts for majority of familial clustering in the common autoimmune diseases. Despite the highly polymorphic nature of HLA class II genes, majority of autoimmune diseases are linked to a limited set of class II-DR or -DQ alleles. Thus a more detailed study of these HLA-DR and -DQ alleles were needed to understand their role in genetic predisposition and pathogenesis of autoimmune diseases. Although in vitro studies using class-II restricted CD4 T cells and purified class II molecules have helped us in understanding some aspects of HLA class-II association with disease, it is difficult to study the role of class II genes in vivo because of heterogeneity of human population, complexity of MHC, and strong linkage disequilibrium among different class II genes. To overcome this problem, we pioneered the generation of HLA-class II transgenic mice to study role of these molecule in inflammatory disease. These HLA class II transgenic mice were used to develop novel in vivo disease model for common autoimmune diseases such as rheumatoid arthritis, multiple sclerosis, insulin-dependent diabetes mellitus, myasthenia gravis, celiac disease, autoimmune relapsing polychondritis, autoimmune myocarditis, thyroiditis, uveitis, as well as other inflammatory disease such as allergy, tuberculosis and toxic shock syndrome. As the T-cell repertoire in these humanized HLA transgenic mice are shaped by human class II molecules, they show the same HLA restriction as humans, implicate potential triggering mechanism and autoantigens, and identify similar antigenic epitopes seen in human. This review describes the value of these humanized transgenic mice in deciphering role of HLA class II molecules in immunopathogenesis of inflammatory diseases.

[Relapsing polychondritis: an analysis of 11 patients]

OBJECTIVE

To analyze 11 patients with relapsing polychondritis reported by 3 hospitals in our country.

PATIENTS AND METHOD

We describe 11 cases of relapsing polychondritis reported by 3 hospitals in our country, analizing gender, age at the beginning of the disease, delay time in diagnosis, clinical manifestations at the beginning of the disease and during follow-up, initial treatment, and treatment in the "chronic phase" of the disease.

RESULTS

We described 8 female patients and 4 males, with a mean age of 40.8 years. The delay time in diagnosis was from 4 months to 4 years. The main manifestations were: auricular chondritis in 8 patients (72.7%), hearing loss in 4 (36.3%), and dysphonia in 4 (36.3%). The complications included subglotic stenosis in 4 patients (36.3%), epiescleritis in 2 (18.1%), 1 retinal and corneal dettachment with macular lesion (9%), conductive and sensorial hearing loss in 2 (18.1%), glomerulonephritis in 2 (18.1%), and mitral and tricuspid insufficiency in one patient (9.0%). All of them received prednisone. Cyclophosphamide, methotrexate, and azathioprine were the most common immunosupressors used.

CONCLUSIONS

This is the largest cohort reported in our country, sharing clinical and outcome patterns reported in other series and in the literature. Response to steroids is good, however, we need to consider other therapeutic options because the disease continues progressing and relapsing.

Anévrysmes aortiques multiples au cours d’une polychondrite atrophiante

BACKGROUND

Although rare, cardiovascular involvement is the second most frequent cause of mortality in chronic relapsing polychondritis behind tracheobronchial tree chondritis. The most frequent cardiovascular complications are valvulopathy and aortic aneurysm.

CASE REPORT

We report a case of chronic relapsing polychondritis with multiple aortic aneurysms that were clinically silent but continued to progress despite systemic corticosteroids and immunosuppressive therapy.

DISCUSSION

Progression of aortic aneurysms and extravascular disease do not appear to be correlated. Although the disease may appear to be in remission, vascular lesions can continue to progress independently. This case shows that medical treatment has little effect on the progression of these aneurysms. Consequently, it is necessary to opt for surgical therapy at the opportune moment.

A case of life-threatening refractory polychondritis successfully treated with combined intensive immunosuppressive therapy with methotrexate

Relapsing polychondritis (RP) is a rare disease of unknown etiology causing systematic inflammation and resulting in destruction of cartilaginous tissues. We describe here an 18-year-old Japanese woman who developed severe airway stenosis as the initial symptom with auricular, nasal, and ocular inflammation. The effect of high dose oral steroid, methylprednisolone pulse therapy, and cyclophosphamide was temporary and her conditioning was worsening. Finally we added methotrexate to the immunosuppressive treatment and achieved reduction of disease activity. This case illustrates the potentially fatal sudden onset of airway inflammation that can occur with this disorder, and the effectiveness of methotrexate.

Relapsing polychondritis presenting as meningoencephalitis with valvular abnormality: a case report

Relapsing polychondritis is a rare rheumatologic disorder that is characterized by recurrent inflammation of selected connective tissue sites and destruction of cartilage throughout the body. We report a case of newly diagnosed relapsing polychondritis in a 40-year-old man presenting with episcleritis, deformed "cauliflower" ears, aortic regurgitation, and aseptic meningoencephalitis. Steroid therapy was instituted with good resolution of his clinical symptoms.

Optic Neuropathy Associated With Periostitis in Relapsing Polychondritis

Optic neuropathy is an uncommon manifestation of relapsing polychondritis (RPC), a rare systemic disease affecting cartilaginous and proteoglycan-rich structures. The optic neuropathy has been attributed to ischemia, intrinsic inflammation of the optic nerve, or spread of inflammation to the nerve from adjacent intraconal orbital tissues. We report a case of recurrent corticosteroid-responsive optic neuropathy in which MRI did not show ocular, optic nerve, or intraconal orbital abnormalities but did show periosteal thickening and enhancement in the apical orbit and adjacent intracranial space consistent with periostitis. The periostitis, which is a manifestation of a systemic vasculitis or an autoimmune reaction to progenitors of cartilage, probably caused the optic neuropathy by compression or inflammation. It is important to recognize this mechanism of optic neuropathy as its imaging features may be a subtle yet critical clue to an underlying systemic condition that can be life-threatening if not properly managed.

Mice expressing HLA-DQ6alpha8beta transgenes develop polychondritis spontaneously

Relapsing polychondritis (RP) is a human autoimmune disease of unknown etiology in which cartilaginous sites are destroyed by cyclic inflammatory episodes beginning, most commonly, during the fourth or fifth decade of life. We have previously described collagen-induced polychondritis that closely mirrors RP occurring in young (6–8 weeks old) HLA-DQ6αβ8αβ transgenic Aβ0 mice, following immunization with heterologous type II collagen (CII).

We present evidence here that transgenic strains expressing the DQ6α8β transgene develop spontaneous polychondritis (SP) at the mouse equivalent of human middle age (4.5–6 months and 40–50 years old, respectively) and display polyarthritis, auricular chondritis and nasal chondritis – three of the most common sites affected in RP. Auricular chondritis in SP, like RP but unlike CII-induced polychondritis, exhibited a relapsing/remitting phenotype, requiring several inflammatory cycles before the cartilage is destroyed. Elevated serum levels of total IgG corresponded with the onset of disease in SP, as in RP and CII-induced polychondritis. No CII-specific immune response was detected in SP, however – more closely mirroring RP, in which as few as 30% of RP patients have been reported to have CII-specific IgG. CII-induced polychondritis displays a strong CII-specific immune response. SP also demonstrated a strong female preponderance, as some workers have reported in RP but has not observed in CII-induced polychondritis. These characteristics of SP allow for the examination of the immunopathogenesis of polychondritis in the absence of an overwhelming CII-specific immune response and the strong adjuvant-induced immunostimulatory influence in CII-induced polychondritis.

This spontaneous model of polychondritis provides a new and unique tool to investigate both the initiatory events as well as the immunopathogenic mechanisms occurring at cartilaginous sites during the cyclic inflammatory assaults of polychondritis.

Vasculitis associated with connective tissue disorders

Vasculitis associated with connective tissue disorders is an important cause of secondary vasculitis about which little is written. When vasculitis occurs in the setting of a preexisting connective tissue disorder, it often correlates with disease severity and portends a poorer prognosis. It may involve virtually any organ system and present in a myriad of ways. Prompt recognition and treatment of vasculitis can dramatically improve the outcome for the patient. This review focuses on recent insights into the clinical presentation and pathogenic mechanisms that may be involved.

Pneumatosis cystoides intestinalis in relapsing polychondritis

Relapsing polychondritis (RP) is a rare systemic disease characterized by an inflammatory process involving predominantly cartilaginous structures. Pneumatosis cystoides intestinalis (PCI) in RP has not been reported previously. We report a case of PCI in RP that was successfully treated with high oxygen and antibiotics.

Relapsing Polychondritis: Prevalence of Expiratory CT Airway Abnormalities

PURPOSE

To retrospectively determine the prevalence of expiratory computed tomographic (CT) abnormalities, including malacia and air trapping, in patients with relapsing polychondritis and to retrospectively determine the frequency with which expiratory abnormalities are accompanied by inspiratory abnormalities on CT scans.

MATERIALS AND METHODS

Institutional review board approval was obtained, and informed consent was not required for this retrospective HIPAA-compliant study. A computerized hospital information system was used to identify all patients with clinically diagnosed or biopsy-proved relapsing polychondritis who were referred for CT airway imaging during a 17-month period. The study cohort comprised 18 patients (15 women, three men; mean age, 47 years; age range, 20-71 years). Multidetector helical CT was performed in all patients by using a standard protocol, which included end-inspiratory and dynamic expiratory volumetric imaging. Two observers who were blinded to the original scan interpretations simultaneously reviewed CT scans. Findings were recorded in consensus. Dynamic expiratory CT scans were assessed for malacia that involved the trachea and main bronchi (reduction in cross-sectional area of more than 50%) and for air trapping (failure of lung parenchyma to increase in attenuation during expiration). Air trapping was visually classified according to pattern and extent (lobular, segmental, lobar, or whole lung). Inspiratory CT scans were evaluated for tracheal and bronchial stenosis (>25% luminal diameter narrowing compared with a corresponding uninvolved segment), wall thickening (>2 mm), and calcification.

RESULTS

Expiratory CT abnormalities were present in 17 (94%) of 18 patients and included malacia in 13 patients (72%) and air trapping in 17 patients (94%). Inspiratory CT abnormalities were found in eight (47%) of 17 patients who had expiratory CT abnormalities. Calcification of the airway walls was present in seven (39%) of 18 patients. All patients who had inspiratory CT abnormalities demonstrated expiratory CT abnormalities.

CONCLUSION

Expiratory CT abnormalities were present in the majority of patients with relapsing polychondritis who were referred for airway imaging, yet only half of these patients demonstrated abnormalities on routine inspiratory CT scans. Thus, dynamic expiratory CT should be a standard component of imaging assessment in patients with relapsing polychondritis.

[Acute mesenteric ischemia in a patient with relapsing polychondritis]

We report about a 43-year old woman with relapsing polychondritis, admitted with progressive malaise, fatigue, anorexia and profound weight loss. Two years ago a nasal chondritis with characteristic changes of the nasal profil, scleritis, laryngitis and unspecific general symptoms (fever, fatigue, signs of a systemic inflammation) developed and relapsing polychondritis was diagnosed. The patient was treated initially with azathioprine followed by methotrexate in combination with ciclosporine and glucocorticoids. During the hospitalization her condition slowly worsened, and crampy abdominal pain developed subsequently with massive tenderness, rebound and guarding. The clinically presumed diagnosis of ileus and peritonitis was radiomorphologically confirmed with signs of enteric perforation and a laparatomy was performed. A complete occlusion of the A. mesenterica superior and stenosis of the truncus coeliacus were diagnosed followed by a revascularization with an aorto-mesenteric bypass and subsequent resection of the necrotic ischemic ileum. An association with various autoimmune disorders including vasculitic syndromes is well known for relapsing polychondritis. The case demonstrated a progressive mesenteric ischemia with the acute exacerbation caused by a vasculitic mesenterial occlusion. The unusual presentation should be considered in the differential diagnosis of uncommon abdominal symptoms during the course of relapsing polychondritis.

Obliterative Microangiopathy Presenting as Chronic Conjunctivitis in a Patient With Relapsing Polychondritis

PURPOSE

To report histopathologic findings and treatment of obliterative microangiopathy in a patient with chronic conjunctivitis due to relapsing polychondritis (RP).

METHODS

This interventional case report describes a 50-year-old woman with relapsing polychondritis was referred to the Ocular Immunology and Uveitis Service for bilateral tearing due to refractory chronic conjunctivitis. Ocular examination revealed the presence of bilateral follicular conjunctivitis. Conjunctival biopsy of the inferior palpebral conjunctiva was performed, and the histopathologic findings guided the therapeutic intervention.

RESULTS

The pathology of the conjunctival biopsy included granulomatous obliterative microangiopathy with numerous eosinophils, plasma cells, lymphocytes, and epithelioid cells in the substantia propia. The chronic conjunctivitis resolved with systemic methotrexate therapy.

CONCLUSIONS

Microangiopathy may cause chronic conjunctivitis in patients with RP and may be a harbinger of evolving nonocular problems as a consequence of incomplete control of this autoimmune disorder. Immunomodulatory therapy should be considered in such cases to prevent possible cardiovascular, renal, respiratory, and neurologic complications of vasculitis. Although methotrexate has been used in treatment of RP-related necrotizing scleritis with poor results, it can be sufficient for the conjunctivitis with microangiopathy associated with RP.

Otologic manifestations of relapsing polychondritis

OBJECTIVE

Relapsing polychondritis (RP) is an episodic disease most likely of autoimmune etiology, characterized by recurrent inflammation of cartilaginous structures.

METHODS

Retrospective case study at two tertiary referral centers with presentation of nine patients with otologic involvement of RP, review of the spectrum of otologic disorders seen, and treatment.

RESULTS

The clinical course of otologic manifestations of RP was highly variable and ranged from mild to moderate. In 6/9 patients there was an association with other autoimmune disorders. In addition to recurrent auricular chondritis, which was present in 8/9 patients, our patients had otitis externa, chronic myringitis, Eustachian tube dysfunction, conductive hearing loss, sensorineural hearing loss, and tinnitus. All patients had their diagnosis of RP made on the basis of their otologic involvement and the response to systemic corticosteroids.

CONCLUSION

The diagnosis of RP is primarily clinical, but laboratory studies and biopsy may contribute as well. Once the diagnosis is suspected, the otolaryngologist should consider consultation with a rheumatologist to assist in the management of additional systemic manifestations.

Uncommon causes of cough: ACCP evidence-based clinical practice guidelines

OBJECTIVES

To describe the uncommon causes of cough.

DESIGN/METHODOLOGY

An English language literature search by MEDLINE citations from 1975 through 2004 was used to identify publications on uncommon pulmonary and nonpulmonary disorders in which cough was present as the major or presenting symptom in >50% of those persons affected by the uncommon diseases.

RESULTS

A substantial number of uncommon or rare pulmonary and nonpulmonary disorders were identified. The uncommon occurrence of these diseases made it difficult to develop a meaningful evidence-based guideline to the diagnosis and therapy of many of the uncommon causes of cough. As cough was the major or presenting symptom, it was usually initially attributed to common respiratory diseases (eg, asthma or bronchitis). As a result, a substantial time lag existed from the onset of cough to the diagnosis of the etiologic entity. Diagnostic tests limited to the respiratory system did not always provide clues to the diagnosis of uncommon causes of cough.

CONCLUSIONS

Cough is the major or presenting symptom in many uncommon pulmonary and nonpulmonary disorders. A strong index of suspicion is essential to consider and diagnose the uncommon causes of cough. The diagnosis and management of cough in patients with uncommon causes of cough is dependent on the underlying etiology.

Meningeal plasma cell granuloma with relapsing polychondritis

✓ Relapsing polychondritis (RP) is a rare systemic disease characterized by recurrent inflammation of the cartilaginous structures and connective tissue. Central nervous system lesions in association with RP have occasionally been reported, but intracranial mass lesions have not been described. The authors report the first such case, in which a 51- year-old man presented with parasagittal meningeal plasma cell granuloma with RP. The mass was subtotally resected and adjuvant radiotherapy was administered. The patient did not experience any recurrence of the lesion during an 8-year follow-up period. In this case, the exact diagnosis of RP was made based on symptoms of respiratory tract chondritis, which was successfully treated by the placement of tracheobronchial stents.

Laryngotracheal involvement as the initial manifestation of relapsing polychondritis

Relapsing polychondritis (RP) is a rare multisystemic disease characterized by recurrent inflammation of cartilaginous and noncartilaginous tissues. When laryngotracheal or bronchial cartilages are involved, the disease can be life-threatening and needs aggressive treatment. Upper airway complaints are rare as initial presentations of RP. Here, however, we present a case of RP, with initial manifestations of cough and dyspnea that were treated as bronchial asthma for 6 months. Subglottic stenosis was found in April 2003, during a bronchoscopic examination, and emergency tracheostomy was performed. Auricular and nasal chondritis and bilateral scleritis developed 3 months after tracheostomy. High doses of methylprednisolone and immunosuppressive agents were used, and active inflammation in the eyes and ears was controlled, but the patient's upper airway was completely collapsed. This case is reported with the hope of increasing awareness about the potential for early upper airway involvement in RP.

Relapsing polychondritis: a rare disease with varying symptoms

PURPOSE

Relapsing polychondritis (RPC) is a rare systemic disease affecting primarily cartilaginous and proteoglycan-rich structures. It is a potentially fatal disease with unknown aetiology. There are no specific tests for RPC. The diagnosis is dependent on clinical criteria, which include chondritis of both auricles, non-erosive inflammatory polyarthritis, nasal chondritis, ocular inflammation, respiratory tract chondritis and cochlear and/or vestibular damage. Ocular symptoms will occur in approximately 60% of RPC patients. As an example, a patient with signs of RPC is described.

METHODS/RESULT

A 30-year-old woman was referred to our department for evaluation of a central corneal ulcer in the left eye. She had a history of recurrent pain in both her auricles and was also found to have a nasal septum perforation. Relapsing polychondritis was suspected.

CONCLUSION

Non-healing corneal ulcers should alert the ophthalmologist to look for unusual reasons for this condition. RPC is one possible cause.

Relapsing polychondritis, chronic hepatitis C virus infection, and mixed cryoglobulemia

OBJECTIVE

Review of relapsing polychondritis (RP) and its association to chronic hepatitis C virus (HCV) infection and mixed cryoglobulinemia.

METHODS

A case of RP associated with HCV infection is reported. The English language medical and scientific literature was reviewed for RP, hepatitis C, and its relation to other connective tissue diseases from February 1966 to January 2003 using MEDLINE.

RESULTS

RP is an uncommon, multisystem disease of unknown etiology characterized by recurrent inflammation of cartilaginous and related tissues, being associated with other diseases in 30% to 35% of cases. HCV infection is a systemic illness with a propensity to trigger or exacerbate autoimmune disorders: eg, essential mixed cryoglobulinemia, membranoproliferative glomerulonephritis, and leukocytoclastic and systemic vasculitis. We could find no previous report of an association between RP with HCV and mixed cryoglobulinemia. Treatment with interferon gamma and ribavirin (IR) not only induced an undetectable viral load, but also resolved symptoms of RP.

CONCLUSIONS

We report a patient with RP, HCV, and mixed cryoglobulinemia. It is unknown if there is a cause-effect or chance relationship. Treatment with IR improved the symptoms of RP. It is not known whether the effects of IR were directly on the RP or suppressed RP indirectly through the actions on the viral load or active hepatitis.

Relapsing polychondritis

SUMMARY

Relapsing polychondritis is a unique, rare autoimmune disorder in which the cartilaginous tissues are the primary targets of destruction but the immune damage can spread to involve noncartilaginous tissues like the kidney, blood vessels, and so forth. The manifestations of the disease can take many different forms and the pathogenesis is still unclear. It may occur in a primary form or it may be associated with other disease states. This article summarizes important aspects of the disease with a focus on recent information regarding clinical manifestations, disease associations, pathogenesis, and advances in therapeutics.

Alopecia areata and relapsing polychondritis or mosaic autoimmunity? The first experience of co-trimoxazole treatment

A 13 year old girl presented with auricular chondritis and recurrent episodes of unexplained chest pain, arthritis, bronchitis, conjunctivitis, prolonged steroid resistant alopecia areata, and a history of recurrent tonsillitis. Both the mosaic of autoimmunity and relapsing polychondritis were considered in the differential diagnosis. The patient was successfully treated with co-trimoxazole. The significance of co-trimoxazole, which is an antibiotic and an immunomodulatory drug, in the treatment of autoimmune disease is discussed.
