Ovarian reserve alterations in premenopausal women with chronic inflammatory rheumatic diseases: impact of rheumatoid arthritis, Behçet’s disease and spondyloarthritis on anti-Müllerian hormone levels

OBJECTIVE Recent publications have shown a negative influence of SLE on female ovarian reserve. Other authors have not found a significant impact of Crohns disease or early RA on anti-Müllerian hormone (AMH) levels. This study aimed to investigate the potential effect of Behçets disease (BD), RA and SpA on ovarian reserve as reflected by serum AMH levels. METHODS Serum samples from 33 RA, 32 SpA and 30 BD patients without previous cytotoxic treatment were analysed and compared with age-matched, healthy controls. AMH was quantified using a standard ELISA with a standard value of 1-8 ng/ml; values <1 ng/ml defined a reduced ovarian reserve. RESULTS Median age was 26, 28.5 and 33 years and median disease duration was 6, 5.9 and 7 years for RA, SpA and BD patients, respectively. Compared with healthy controls, patients had significantly reduced AMH levels, with a median value for RA of 1.8 ng/ml (control 2.4 ng/ml; P = 0.009), for SpA of 1.5 ng/ml (control 2.3 ng/ml; P = 0.013) and for BD of 1.1 ng/ml (control 1.9 ng/ml; P = 0.007). HLA-B27 had a negative influence on ovarian reserve in SpA patients, whereas other serological parameters did not in the other diseases. CONCLUSION This is the first study to show a reduced ovarian reserve in patients with RA, SpA or BD. Together with our findings in SLE, we conclude a negative influence of chronic rheumatic diseases on ovarian reserve.

Tocilizumab in Uveitic Macular Edema Refractory to Previous Immunomodulatory Treatment

ABSTRACT Purpose: To analyze the efficacy of tocilizumab in uveitic macular edema (ME) resistant to various immunomodulatory drugs. Methods: Patients received tocilizumab every 4 weeks intravenously. Central foveal thickness (CFT) was assessed by optical coherence tomography (OCT). Results: Five patients (8 eyes) who were ineffectively pretreated with systemic prednisolone, at least one immunosuppressive drug, and at least one biologic drug for uveitic macular edema were included in the study. At 3 months, a response of ME (≥25% reduction in CFT) was observed in 6 eyes (75.0%) of 5 patients. During follow-up, complete resolution of ME was achieved in 5 eyes (62.5%) of 4 patients. Improvement of BCVA was observed in 3 eyes of 3 patients, and stabilization in 3 eyes of 3 patients. Tocilizumab was well tolerated, and no severe side effects occurred. Conclusions: Treatment with tocilizumab can be considered in chronic uveitic macular edema even if previous immunomodulatory therapy has failed.

MRI parametric monitoring of biological therapies in primary large vessel vasculitides: a pilot study

OBJECTIVE To evaluate the development of characteristic MRI changes in patients with primary large-vessel vasculitis (LVV) when treated with biological therapies. METHODS 12 patients with primary LVV (8 patients with Takayasu arteritis and 4 patients with giant-cell arteritis) received biological therapy with tumour necrosis factor-α blockers (n = 9) or an interleukin-6 inhibitor (n = 3). MRI investigations were performed at baseline (pre-treatment) and follow-up. All patients underwent the same MRI/MR angiography (MRA) protocol. Laboratory parameters (C-reactive protein and erythrocyte sedimentation rate) and clinical response (Birmingham Vasculitis Activity Score) were assessed. RESULTS Wall thickness was 4.2 ± 0.3 mm pre-treatment and significantly decreased to 3.2 ± 0.3 mm post treatment in 9/12 patients. Mural enhancement was increased in all 12/12 patients with LVV, and subsided with therapy in 5/12 patients. Mural oedema or ill-defined contour were less prevalent but also improved with biological treatment. C-reactive protein and erythrocyte sedimentation rate levels decreased, and clinical assessment revealed a significant improvement from pre-treatment to post-treatment. However, the course of imaging characteristics often did not parallel that of laboratory or clinical parameters. In all three patients receiving interleukin-6 blockade, laboratory markers and clinical scores normalized despite persistent vascular inflammation in one patient which was disclosed by MRI. CONCLUSION Contrast-enhanced MRI/MRA may be useful when evaluating the development of disease activity in primary LVV under biological therapies. A high degree of suspicion and regular imaging follow-up is needed to detect persistent inflammation. ADVANCES IN KNOWLEDGE This is the first study investigating the applicability of different MRI/MRA parameters for monitoring biological therapy in patients with primary LVV.

Perfusion-based assessment of disease activity in untreated and treated patients with aortitis and chronic periaortitis: correlation with CT morphological, clinical and serological data

OBJECTIVE To evaluate the role of perfusion-based assessment of inflammatory activity in patients with treated and untreated aortitis and chronic periaortitis as compared with clinical and serological markers. METHODS 35 patients (20 females; median age 66 years) with (peri) aortitis were retrospectively evaluated. All patients had clinical symptoms prompting at the time of imaging. All patients first underwent whole-body contrast-enhanced CT and subsequently segmental volume perfusion CT for assessment of the degree of vascularization of (peri) aortitis as a surrogate marker for inflammatory activity. Blood flow, blood volume, volume transfer constant (k-trans), time to peak and mean transit time were determined. The thickness of the increased connective tissue formation was measured. Perfusion data were correlated with clinical symptoms and acute-phase inflammatory parameters such as C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and leukocyte number. RESULTS 21 of 35 patients were untreated and 14 of 35 had previous/ongoing immunosuppression. The interobserver agreement was good (κ = 0.78) for all perfusion parameters. Average values of perfusion parameters were higher in untreated patients but remained abnormally elevated in treated patients as well. Perfusion data and ESR and CRP correlated well both in aortitis (p < 0.05) and in periaortitis (p < 0.05). In periaortitis, perfusion parameters agreed well with ESR and CRP values (p < 0.05) only in untreated patients. CONCLUSION Perfusion CT parameters in untreated aortitis and chronic periaortitis correlate well with serological markers with respect to disease activity assessment. However, in treated periaortitis, correlations were weak, suggesting an increased role for (perfusion-based) imaging. ADVANCES IN KNOWLEDGE Volume perfusion CT may be used for diagnosis of aortitis/periaortitis.

Monitoring Disease Activity in Patients with Aortitis and Chronic Periaortitis Undergoing Immunosuppressive Therapy by Perfusion CT

RATIONALE AND OBJECTIVES To evaluate the role of perfusion CT for monitoring inflammatory activity in patients with aortitis and chronic periaortitis undergoing immunosuppressive therapy. MATERIALS AND METHODS Seventeen symptomatic patients (median age 68.5 years) who underwent perfusion-based computed tomography (CT) monitoring after diagnostic contrast-enhanced CT were retrospectively included in this study. Blood flow (BF), blood volume (BV), volume transfer constant (k-trans), time to peak, and mean transit time were determined by setting circular regions of interest in prominently thickened parts of the vessel wall or perfused surrounding tissue at sites where the perfusion CT color maps showed a maximum BF value. Differences in CT perfusion and, morphological parameters, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) were tested for significance during therapy. RESULTS In all patients BF and BV dropped at second perfusion CT (P < 0.05). In aortitis patients, CRP dropped from 3.86 ± 5.31 mg/dL to 0.9 ± 1.37 mg/dL and in periaortitis patients from 1.78 ± 2.25 mg/dL to 0.79 ± 1.55 mg/dL, whereas ESR dropped from 45.71 ± 37.59 seconds to 8.57 ± 3.1 seconds and 36.78 ± 34.67 seconds to 17.22 ± 21.82 seconds in aortitis and in periaortitis, respectively. CONCLUSIONS The course of perfusion CT parameters in aortitis and chronic periaortitis undergoing immunosuppressive therapy dropped at different extent after therapy.

Whole Exome Sequencing Identifies Rare Protein‐Coding Variants in Behçet's Disease

Behçets disease (BD) is a systemic inflammatory disease with an incompletely understood etiology. Despite the identification of multiple common genetic variants associated with BD, rare genetic variants have been less explored. We undertook this study to investigate the role of rare variants in BD by performing whole exome sequencing in BD patients of European descent.

Morbus Behçet@@@Behçet’s disease

Behçets disease is a systemic disorder with the histopathological correlate of leukocytoclastic vasculitis. Pathogenetically, besides a strong genetic component participation of the innate immune system and an autoinflammatory component are discussed. The disease is most common in countries along the former silk route but in Germany the disease is rare (prevalence approximately 0.6/100,000). Oral aphthous ulcers are the main symptom, followed by skin manifestations, genital ulcers and oligoarthritis of large joints. Severe manifestations, threatening quality of life and even life itself, are the gastrointestinal manifestations which often perforate, arterial, mainly pulmonary arterial aneurysms which cause life-threatening bleeding, CNS manifestations and ocular disease, which with occlusive retinal vasculitis often leads to blindness. For milder manifestations low-dose steroids and colchicine are used, for moderate manifestations such as arthritis or ocular disease not immediately threatening visual acuity, azathioprin or cyclosporin A are combined with steroids. For severe manifestations, interferon-alpha, TNF-antagonists or cytotoxic drugs are recommended. Interleukin 1 (IL-1) antagonists are currently being examined in clinical studies.

Extraokuläre Manifestationen des Morbus Behçet

Behcets disease is a multisystem disorder with the histopathological correlate of leukocytoclastic vasculitis. The classification criteria for the disease include the presence of recurrent oral aphthous ulcers combined with at least two other manifestations, such as genital aphthous ulcers, skin manifestations (mostly erythema nodosa or pseudofolliculitis) and ocular manifestations (panuveitis or posterior uveitis with retinal vasculitis). A positive pathergy test is regarded as pathognomonic for the disease and a sterile papulopustule occurs after a sterile needle prick of the forearm. However, this test is positive in only 15% of the patients. The prognosis of Behcets disease becomes unfavorable when vital organs are involved. This is the case for involvement of the central nervous system which occurs in 10% of patients, arterial and pulmonary arterial aneurysms and gastrointestinal involvement, which clinically and histopathologically is difficult to differentiate from inflammatory bowel disease but tends to perforate. Oligoarthritis, which occurs in approximately 50% of the patients, causes problems concerning the differential diagnosis from classical forms of spondyloarthritis. Behcets disease is associated with HLA-B51 in 50-80% of the cases depending on the country of origin of the patient. The prognosis becomes unfavorable if the disease manifests in young male patients. The treatment of extraocular manifestations depends on the aggressiveness. Milder manifestations are treated with low dose prednisolone and steroid sparing immunosuppressants, such as azathioprine or cyclosporine A. In cases with more severe manifestations, such as central nervous system (CNS) involvement cyclophosphamide or TNF antagonists and in selected cases also interferon alpha can be considered.
