Relapsing polychondritis with aortic arch aneurysm and aortic arch syndrome

Non-infectious diseases of the aorta and large arteries

This article describes the various forms of inflammatory lesions of the aorta and large arteries, including chronic periaortitis, as well as the diagnostic methods are considered. Large vessel vasculitis represent the most common entities, however, there is also an association with other rheumatological or inflammatory diseases, drug-induced or paraneoplastic entities. Instrumental imaging modalities play an important role in the diagnosis.

Large-vessel Vasculitis Affecting the Aorta and its Branches in Relapsing Polychondritis: Case Series and Systematic Review of the Literature

OBJECTIVE

To describe the features of large-vessel vasculitis (LVV) as it affects the aorta and its branches in patients with relapsing polychondritis (RP).

METHODS

Retrospective data and systematic literature review.

RESULTS

Twenty-one patients were identified. LVV diagnosis was subsequent to RP and associated with extrachondral involvement in the majority of patients. Supraaortic vessels were more frequently involved (82%). Fourteen patients (67%) were treated with a conventional synthetic disease-modifying antirheumatic drug (csDMARD) and 7 (33%) with a biological DMARD (bDMARD). Vascular interventional procedures were performed in 10 patients (48%). Premature death due to cardiovascular complications was reported in 3 cases (14%).

CONCLUSION

Extraaortic LVV is a serious and overlooked RP manifestation. All patients with RP should be investigated for LVV.

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.

Aortic involvement in relapsing polychondritis: case-based review

Relapsing polychondritis is a systemic inflammatory disease that mainly affects ears, nose, eyes, joints, and large airway. Relapsing polychondritis may also affect cardiac valves and large vessels with the aorta being most frequently involved. We conducted a systematic literature review to delineate the clinical characteristics, treatment, and outcome of relapsing polychondritis patients with aortic involvement including thoracic and abdominal aorta, aortic valve, and coronary arteries. 113 patients reported in 85 manuscripts were retrieved through the systematic literature search and references of the selected manuscripts. With the addition of a patient from our center, a total of 114 patients were included in the analyses. Aortic vessel involvement was the predominant type of involvement that was identified in 93 (82%) patients, while aortic valve involvement was identified in 41 patients (36%). The median age at aortic involvement was 37 years [IQR: 30-53] with a delay of 5 years [IQR: 1-8] between first relapsing polychondritis symptom and aortic involvement. Nineteen percent of the patients were asymptomatic at the time of aortic involvement diagnosis. The initial treatment was immunosuppressives in 41 patients (56%) and surgery in 28 patients (38%). The mortality ratio was 27% in a 24 month follow-up [IQR: 7.5-54 months]. Aortic dissection or rupture was the most frequent causes of mortality. Concomitant coronary artery involvement suggested a worse outcome. Aortic involvement in relapsing polychondritis is a mortal complication despite medical and surgical treatments. It may be asymptomatic in 19% of the patients which warrants the importance of screening.

Insights into imaging of aortitis

BACKGROUND

Aortitis is a subtype of the more general term "vasculitis", an inflammatory condition of infectious or noninfectious origin involving the vessel wall. The term "vasculitis" refers to a broad spectrum of diseases with different aetiologies, pathophysiologies, clinical presentations and prognoses. The clinical manifestations are nonspecific, as are the laboratory findings such as pain, fever, weight loss, vascular insufficiency and elevated levels of acute phase reactants, as well as other systemic manifestations, and sometimes may mimic other entities. Thus, if not suspected as part of the initial differential diagnosis, aortitis can be overlooked during the workup of patients with constitutional symptoms and systemic disorders.

METHODS

Imaging is rarely used for the primary diagnosis, but imaging findings, although nonspecific, can help in the assessment of these patients and is often required for making the final diagnosis. Imaging can be critical in the initiation of appropriate management and therapy.

RESULTS

Noninvasive cross-sectional imaging modalities such as contrast-enhanced CT, magnetic resonance (MR) imaging, nuclear medicine and in particular positron emission tomography (PET) are the leading modalities in modern diagnostic imaging of aortitis for both the initial diagnosis and follow-up.

CONCLUSION

This review focusses on the most common manifestations of aortitis with which radiologists should be familiar. TEACHING POINTS : • Aortitis is an inflammatory condition of infectious/noninfectious origin involving the vessel wall. • Imaging findings can help in the assessment of aortitis and are often crucial for the final diagnosis. • Contrast-enhanced CT, MRI and PET-CT are used for both the initial diagnosis and follow-up of aortitis.

[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.

Transverse Aortic Arch Replacement Associated with MAGIC Syndrome: Case Report and Literature Review

We report a case of ascending and transverse aortic arch aneurysm repair with aortic valve replacement in a patient with MAGIC syndrome (mouth and genital ulcers with inflamed cartilage), the unusual setting of both Behçet's disease and relapsing polychondritis.

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.

Relapsing polychondritis: a clinical review

OBJECTIVE

This study comprehensively reviews the literature related to relapsing polychondritis (RP).

METHODS

A detailed search via MEDLINE (PubMed) was performed using relapsing polychondritis as the key term. Relevant articles were analyzed with a focus on history, epidemiology, etiology, pathogenesis, clinical manifestations, diagnosis, treatment, and prognosis of RP.

RESULTS

RP is a rare episodic and progressive inflammatory disease of presumed autoimmune etiology first described in 1923. RP affects cartilage in multiple organs, such as the ear, nose, larynx, trachea, bronchi, and joints. In addition, it can affect proteoglycan-rich tissues, such as the eyes, aorta, heart, and skin. The diagnosis of RP is based on the presence of clinical criteria. A standardized therapeutic protocol for RP has not been established. Nonsteroidal anti-inflammatory drugs, dapsone and/or colchicine, may control disease activity in some patients. In other patients, immunosuppressive drugs and prednisone have been effective. RP is a potentially lethal disease; pulmonary infection, systemic vasculitis, airway collapse, and renal failure are the most common causes of death. Earlier studies indicate survival rates between 70% at 4 years and 55% at 10 years. In a recent study, a survival rate of 94% at 8 years may be due to improved medical and surgical management.

CONCLUSIONS

RP is a rare, multisystemic, and potentially fatal disease. The pathogenesis and optimal therapeutic approach to patients with RP is poorly understood.

Vasculitic peripheral ulcerative keratitis

The onset of peripheral ulcerative keratitis in the course of a connective tissue disorder, such as rheumatoid arthritis, relapsing polychondritis, or systemic lupus erythematosus, may reflect the presence of potentially lethal systemic vasculitis. Moreover, peripheral ulcerative keratitis may be the first sign of systemic necrotizing vasculitis in patients with Wegener's granulomatosis, polyarteritis nodosa, microscopic polyangiitis, or Churg-Strauss syndrome. Although the exact pathogenesis of this severe corneal inflammation and destruction is not well understood, evidence points to a dysfunction in immunoregulation with immune complexes formed in response to autoantigens or to some unknown microbial antigen depositing in scleral and limbal vessels. These events lead to changes that are mainly responsible for the resulting tissue damage. In pauci-immune vasculitides positive for antineutrophil cytoplasmic antibodies, cell-mediated cytotoxicity may play an important role in the pathogenesis of peripheral ulcerative keratitis. Untreated systemic conditions such as those mentioned above may carry a grave prognosis for the eye and may also be life-threatening. Immunosuppressive therapy with corticosteroids and cytotoxic agents is, we believe, mandatory in the treatment of these multisystem disorders associated with vasculitic peripheral ulcerative keratitis.

Relapsing polychondritis: bone marrow and circular fibrous nodules in the aorta

A case is reported of extensive aortic calcification, bone formation, and haemopoietic tissue in a woman with relapsing polychondritis. An additional feature was 'clock face' nodules of collagen in the aorta.

Ocular and systemic findings in relapsing polychondritis

The ocular and systemic findings in 112 Mayo Clinic patients with relapsing polychondritis were reviewed. The incidence of males and females was equal, with median age at diagnosis of 51 years and the median follow-up of 6 years. Most patients had several organ systems involved at the time of the diagnosis. Twenty-one patients had ocular symptoms at the onset, and 57 developed ocular symptoms during their course. Major ocular complications included proptosis, lid edema, episcleritis/scleritis, corneal infiltrates/thinning, iridocyclitis, retinopathy, and optic neuritis. The major system involvement included otorhinolaryngeal, respiratory, arthritic, renal, cardiovascular, dermatologic, and neurologic diseases. Generally, laboratory studies were not helpful in making the diagnosis but were valuable in monitoring the disease. Based on the experience in these cases, the indications for the various therapeutic modalities are offered.
