RESUMO
OBJECTIVES: The incidence of anti-neutrophil cytoplasmic antibodies (ANCA) associated vasculitis (AAV) shows disparate results due to variable classification criteria and heterogeneous-population series. We aimed to estimate the incidence of AAV in a well-defined population with standardized classification criteria. METHODS: Population-based study of AAV patients diagnosed from January 2000 to December 2023 in Cantabria, Northern Spain. Patients were classified according to ACR/EULAR 2022 into granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), or unclassified vasculitis if the criteria were not met. Eosinophilic granulomatosis with polyangiitis (EGPA) patients were not included. The annual incidence rates were estimated by cases over 1,000 000 (106) (95% CI) including overall AVV, type of AAV, sex, and year of diagnosis. A literature review was also performed. RESULTS: We included 152 (80/72 men; mean age; 70.6 ± 13.18 years) patients. They were classified as MPA (67; 44%), GPA (64; 42.2%), and unclassified vasculitis (21; 13.8%). Annual incidence was 13.4 (10-16.8)/106 [male 14.5 (10.5-18.5); female 12.1 (8.7-15.6)]. The Annual incidence of MPA was 5.9 (4-7.8)/106 and GPA 5.6 (3.9-7.3)/106. The mean Annual incidence increased from 6.1 (4.5-7.7)/106-16.5 (5.6-27.4)/106 in the last three years, particularly, in GPA from 2.3 (0.3-4.9)/106-8.2 (2-14.5)/106. The prevalence of AAV was 184.7 (181-188)/106. CONCLUSION: During a 20-year period we found that the incidence of AAV (GPA and MPA) in Northern Spain is higher than Southern Spain, but lower than Northern European countries. An increase in the incidence was observed in the last years.
RESUMO
ITGAM-ITGAX (rs11150612, rs11574637), VAV3 rs17019602, CARD9 rs4077515, DEFA (rs2738048, rs10086568), and HORMAD2 rs2412971 are mucosal immune defence polymorphisms, that have an impact on IgA production, described as risk loci for IgA nephropathy (IgAN). Since IgAN and Immunoglobulin-A vasculitis (IgAV) share molecular mechanisms, with the aberrant deposit of IgA1 being the main pathophysiologic feature of both entities, we assessed the potential influence of the seven abovementioned polymorphisms on IgAV pathogenesis. These seven variants were genotyped in 381 Caucasian IgAV patients and 997 matched healthy controls. No statistically significant differences were observed in the genotype and allele frequencies of these seven polymorphisms when the whole cohort of IgAV patients and those with nephritis were compared to controls. Similar genotype and allele frequencies of all polymorphisms were disclosed when IgAV patients were stratified according to the age at disease onset or the presence/absence of gastrointestinal or renal manifestations. Likewise, no ITGAM-ITGAX and DEFA haplotype differences were observed when the whole cohort of IgAV patients, along with those with nephritis and controls, as well as IgAV patients, stratified according to the abovementioned clinical characteristics, were compared. Our results suggest that mucosal immune defence polymorphisms do not represent novel genetic risk factors for IgAV pathogenesis.

OBJECTIVES: Rapid control of intraocular inflammation in non-infectious uveitis (NIU) is mandatory to avoid irreversible structural and functional damage. In this study, we assessed the efficacy and safety of intravenous methylprednisolone (IVMP) pulses in the treatment of NIU. METHODS: A retrospective case series of 112 patients who received IVMP for the treatment of NIU, either isolated or associated with different underlying diseases, was studied. Intraocular inflammation (anterior chamber cells and vitritis) was the primary outcome measure. Secondary outcome measures were macular thickness and best corrected visual acuity (BCVA). Patients were assessed at baseline visit, and at days 2-5, 7, 15 and 30 after initiation of IVMP pulse therapy. RESULTS: A total of 112 patients (mean age 42±14.5 yrs) were assessed. An underlying immune-mediated disease was diagnosed in 73 patients. Inflammatory ocular patterns were panuveitis (n=68), posterior uveitis (n=30), anterior uveitis (AU) (n=12), and intermediate uveitis (n=2). Additionally, patients presented cystoid macular oedema (CME) (n=50), retinal vasculitis (n=37), and exudative retinal detachment (n=31). Therapies used before IVMP included intraocular glucocorticoids (n=4), high-dose oral systemic glucocorticoids (n=77), and conventional (n=107) or biologic (n=40) immunosuppressive drugs. IVMP dose ranged from 80 to 1,000 mg/day for 3-5 consecutive days. Improvement was observed in AU, vitritis, BCVA, CME, and retinal vasculitis. At first month evaluation, total remission was achieved in 19 patients. Side effects of IVMP were respiratory infections (n=3), uncontrolled hyperglycaemia (n=1), herpes zoster (n=1), and oral candidiasis (n=1). CONCLUSIONS: IVMP pulse therapy was effective and safe, and achieved rapid control of NIU.

OBJECTIVES: Anti-IL6R tocilizumab (TCZ) therapy has proved to be useful in the treatment of refractory ocular and/or neurological involvement of Behçet's disease (BD). However, TCZ efficacy in other BD manifestations remains unclear. In this study we aimed to assess the efficacy of TCZ in the different clinical phenotypes of BD. METHODS: This is a multicentre study of BD patients treated with TCZ, due to refractivity to standard systemic treatment. RESULTS: We studied 16 patients (10 men/6 women); mean age 36.5±18.2 years. The main clinical manifestations at TCZ onset were ocular, oral and/or genital ulcers, arthritis, folliculitis and/or neurological involvement. Before TCZ, they had received several conventional and/or biological immunosuppressants, such as methotrexate, cyclosporine, adalimumab or infliximab. TCZ was used in monotherapy or combined with conventional immunosuppressive drugs. The main indications for TCZ prescription were refractory uveitis (n=14) and refractory neurobehçet (n=2). After a median [IQR] follow-up of 20 [9-45] months using TCZ, neurological and ocular domains improved in most cases with complete remission in most patients with uveitis. Articular and peripheral venous manifestations also experienced a favourable evolution. However, oral/genital ulcers, skin lesions and intestinal manifestations followed a torpid course. CONCLUSIONS: TCZ is effective in BD with major clinical involvement. However, it does not seem to be effective in oral/genital ulcers or skin lesions.

OBJECTIVES: Clinicians often face the challenge of providing effective and safe therapy for pregnant women with uveitis. Certolizumab pegol (CZP) differs from other anti-TNFα agents due to its limited placental transfer. In this study we assessed the efficacy of CZP in pregnant women with uveitis. We also provided information on outcomes of pregnant women and neonates exposed to CZP. METHODS: We carried out a multicentre study of women with uveitis who received CZP during pregnancy and their neonates. The main visual outcomes were visual acuity (VA), intraocular inflammation and corticosteroid-sparing effect. Pregnancy outcomes, maternal and neonatal infections and congenital malformations were also assessed. RESULTS: We studied 14 women (23 affected eyes); mean age of 34.3±5.5 years. The underlying diseases were spondyloarthritis (n=7), idiopathic (n=2), and Vogt-Koyanagi-Harada, rheumatoid arthritis, juvenile idiopathic arthritis, punctate inner choroidopathy and Behçet's disease (1 each). The patterns of ocular involvement were anterior (n=10), posterior (n=2), intermediate (n=1), panuveitis (n=1). Cystoid macular oedema was present in one patient (1 eye). Uveitis was bilateral in nine cases and chronic in seven patients. CZP was started before getting pregnant in ten patients and after conceiving in four. All patients achieved or maintained ocular remission throughout pregnancy. Fifteen healthy infants were born. Only one woman presented a mild infection during pregnancy. Neither infections nor malformations were observed in neonates after a follow-up of 6 months. Six infants were breastfed and all of them received scheduled vaccinations without complications. CONCLUSIONS: Certolizumab pegol is effective and safe in women with uveitis during pregnancy.

OBJECTIVES: The objective of the present study was to assess the efficacy of apremilast (APR) in the management of refractory oral and/or genital ulcers in patients with Behçet's disease (BD). METHODS: National multicentre open-label observational study on BD patients with recurrent oral and/or genital ulcers. In all cases orogenital ulcers were refractory to conventional therapy. APR was given and maintained at standard dose of 30 mg twice daily. The main outcome was the achievement of oral and/or genital ulcers remission. Efficacy of APR for other clinical manifestations was also evaluated. RESULTS: We included 51 patients (35 women/16 men; mean age 44.7±13.2 years). Before APR, all patients had received several systemic conventional and/or biologic drugs. APR was initiated because of refractory oral (n=19) or genital (n=2) aphthous ulcers or both (n=30). Other manifestations found at APR onset were arthralgia/arthritis (n=16), folliculitis/pseudofolliculitis (n=14), erythema nodosum (n=3), furunculosis (n=2), paradoxical psoriasis induced by TNF-α-inhibitors (n=2), ileitis (n=2), deep venous thrombosis (n=2), leg ulcers (n=1), erythematosus and scaly skin lesions (n=1), fever (n=1), unilateral anterior uveitis (n=1) and neuro Behçet (n=1). After a mean follow-up of 8.5±6.9 months, most patients had experienced improvement of orogenital ulcers and prednisone dose had been successfully reduced or discontinued. APR also yielded improvement of some non-aphthous manifestations such as the cutaneous follicular and intestinal manifestations. However, the effect on musculoskeletal manifestations was variable. CONCLUSIONS: APR yielded a rapid and maintained improvement of refractory mucocutaneous ulcers of BD, even in patients refractory to several systemic drugs including biologic therapy.

The aim of this study is to compare the efficacy and safety of biological therapy with cyclosporin A (CsA), azathioprine (AZA), or placebo in uveitis flares and other ocular outcomes in patients with Behçet disease. A comprehensive and sensitive search in MEDLINE, EMBASE, and the Cochrane Library was performed. We selected articles including: (1) adult patients with Behçet's and uveitis; (2) on biological therapies; (3) placebo or active control with CsA or AZA; (4) analyzing efficacy (number of uveitis flares, macular edema, etc.) and/or safety outcomes. Meta-analyses, systematic reviews, clinical trials, and observational studies with > 10 patients were included. The selection, data collection and quality assessment (Oxford scale) was carried out by 2 reviewers independently. Nine articles of moderate quality were included (6 randomized clinical trials and 3 retrospective studies) involving 378 patients. Most of them, apart from the study drugs received systemic corticosteroids and other immunosuppressant drugs. Infliximab was more effective than CsA in reducing short-term uveitis flares and severe complications of retinal vasculitis in the long term. Rituximab was similar to a combination of cytotoxic drugs in improving inflammatory activity. In patients with active uveitis adalimumab was associated with a lower risk of uveitic flare or visual impairment, and in patients with inactive uveitis to a significantly lowered the risk of flare upon corticosteroid withdrawal. Secukinumab and daclizumab were not superior to placebo in reducing uveitis flares, like interferonα compared to other drugs. Our results highlight the need for better designed comparative studies on Behçet's uveitis.

Objective: To assess the efficacy of tocilizumab (TCZ) in refractory uveitis of Behçet's disease (BD). Methods: Multicentre study of patients with BD-associated uveitis. Patients were refractory to conventional and biologic immunosuppressive drugs. The main outcome measures were intraocular inflammation, macular thickness, visual acuity and corticosteroid-sparing effects. Results: We studied 11 patients (7 men) (20 affected eyes); median age 35 years. Uveitis was bilateral in nine patients. The patterns of ocular involvement were panuveitis (n = 8, with retinal vasculitis in 4), anterior uveitis (n = 2) and posterior uveitis (n = 1). Cystoid macular oedema was present in seven patients. The clinical course was recurrent (n = 7) or chronic (n = 4). Before TCZ, patients had received systemic corticosteroids, conventional immunosuppressants and the following biologic agents: adalimumab (n = 8), infliximab (n = 4), canakimumab (n = 1), golimumab (n = 3), etanercept (n = 1). TCZ was used as monotherapy or combined with conventional immunosuppressants at 8 mg/kg/i.v./4 weeks (n = 10) or 162 mg/s.c./week (n = 1). At TCZ onset the following extraocular manifestations were present: oral and/or genital ulcers (n = 7), arthritis (n = 4), folliculitis/pseudofolliculitis (n = 4), erythema nodosum (n = 2), livedo reticularis (n = 1) and neurological involvement (n = 2). TCZ yielded rapid and maintained improvement in all ocular parameters of the patients, with complete remission in eight of them. However, this was not the case for the extraocular manifestations, since TCZ was only effective in three of them. After a mean (s.d.) follow-up of 9.5 (8.05) months, TCZ was withdrawn in two cases, due to a severe infusion reaction and arthritis impairment, respectively. Conclusion: TCZ could be a therapeutic option in patients with BD and refractory uveitis.

PURPOSE: To assess efficacy, safety, and cost-effectiveness of adalimumab (ADA) therapy optimization in a large series of patients with uveitis due to Behçet disease (BD) who achieved remission after the use of this biologic agent. DESIGN: Open-label multicenter study of ADA-treated patients with BD uveitis refractory to conventional immunosuppressants. SUBJECTS: Sixty-five of 74 patients with uveitis due to BD, who achieved remission after a median ADA duration of 6 (range, 3-12) months. ADA was optimized in 23 (35.4%) of them. This biologic agent was maintained at a dose of 40 mg/subcutaneously/2 weeks in the remaining 42 patients. METHODS: After remission, based on a shared decision between the patient and the treating physician, ADA was optimized. When agreement between patient and physician was reached, optimization was performed by prolonging the ADA dosing interval progressively. Comparison between optimized and nonoptimized patients was performed. MAIN OUTCOME MEASURES: Efficacy, safety, and cost-effectiveness in optimized and nonoptimized groups. To determine efficacy, intraocular inflammation (anterior chamber cells, vitritis, and retinal vasculitis), macular thickness, visual acuity, and the sparing effect of glucocorticoids were assessed. RESULTS: No demographic or ocular differences were found at the time of ADA onset between the optimized and the nonoptimized groups. Most ocular outcomes were similar after a mean ± standard deviation follow-up of 34.7±13.3 and 26±21.3 months in the optimized and nonoptimized groups, respectively. However, relevant adverse effects were only seen in the nonoptimized group (lymphoma, pneumonia, severe local reaction at the injection site, and bacteremia by Escherichia coli, 1 each). Moreover, the mean ADA treatment costs were lower in the optimized group than in the nonoptimized group (6101.25 euros/patient/year vs. 12 339.48; P < 0.01). CONCLUSION: ADA optimization in BD uveitis refractory to conventional therapy is effective, safe, and cost-effective.

OBJECTIVES: To assess the efficacy of golimumab (GLM), a fully humanised anti-TNF-α monoclonal antibody, in refractory juvenile idiopathic arthritis (JIA)-associated uveitis. METHODS: This was a multicentre study of JIA-associated uveitis refractory to standard synthetic immunosuppressive drugs and in most cases to other anti-TNF-α agents. Results were expressed as mean±standard deviation or as median (range or interquartile range). The Wilcoxon signed-rank test was used to compare continuous variables. A literature review of the efficacy of GLM in uveitis related to JIA was also conducted. RESULTS: We studied 7 patients (5 females; mean age 21.7±7.5 years; 13 affected eyes). Uveitis was bilateral in 6. Cystoid macular oedema (CME) occurred in 3 patients (5 eyes). Besides corticosteroids and synthetic immunosuppressive drugs, patients had received before GLM a median of 2 biologic agents (range 0-3) including adalimumab (n=6), etanercept (n=2), infliximab (n=3) and abatacept (n=2). GLM dose was 50 mg/sc every 4 weeks. After 6 months of therapy the number of anterior chamber cells decreased from 1 [0.25-1.5] to 0 [0-0.5] (p=0.02) and optical coherence tomography (in patients with CME) from 313.6±77.05 to 261.4±75.1 µm (p=0.03). The best-corrected visual acuity increased from 0.5 to 0.62 (p=0.018). Complete remission of uveitis was achieved in 4 of 7 patients after 16.8±11.4 months of follow-up. However, 2 of the seven patients had to be switched to tocilizumab due to inefficacy. Local erythema at the injection site was observed in 2. CONCLUSIONS: GLM may be considered in the management of refractory JIA-related uveitis.

OBJECTIVES: To determine if cutaneous vasculitis (CV) associated with severe infection has some histopathologic findings that may help us to differentiate patients with this condition from other patients with CV. METHODS: We reviewed the skin biopsy specimens of patients with leukocytoclastic CV associated with a severe bacterial infection. Histopathologic findings of these patients were compared with those observed in leukocytoclastic CV secondary to other causes. Biopsy-proven leukocytoclastic CV were stratified as follows: group a): CV associated with severe underlying bacterial infection; group b): CV without severe bacterial infection but with systemic involvement; group c): CV without systemic involvement. Slides were reviewed by expert pathologists that were blind to the clinical information. The severity of vascular lesions was measured according to a semiquantitative scale (Hodge index). A comparative study between group a) and the other groups was conducted. RESULTS: group a) included 12 patients (2 women/10 men), mean age± SD 56±15 years; group b) 21 patients (10 women/11 men), 52±18 years; and group c) 19 patients (12 women/7 men), 59±24 years. Presence of neutrophilia was significantly increased in biopsies from group a) when compared with the other two groups. Also, a trend to higher frequency of pustular dermatosis was found in patients from group a). Hodge index, degree of inflammatory infiltrate and deep arterioles involvement were similar in all groups. CONCLUSIONS: Neutrophilia is common in skin biopsies of patients with CV associated with severe bacterial infection. No other histopathological findings help us to establish the presence of a severe underlying infection.

OBJECTIVES: To assess the efficacy of tocilizumab (TCZ) in patients with Takayasu arteritis (TA). METHODS: Multicentre open-label retrospective study. RESULTS: Eight patients (all women) with a mean age of 34±16 years, median 36 years (range: 7-57) were assessed. The main clinical features at TCZ therapy onset were: constitutional symptoms (n=4), fever (n=3), headache (n=2), chest pain (n=1), abdominal pain (n=1), mesenteric ischaemia (n=1), myalgia involving the lower limbs (n=1), cerebral vascular insufficiency (n=1), malaise (n=1), upper limb claudication (n=1) and nodular scleritis (n=1). Besides corticosteroids and before TCZ treatment onset, 7 of 8 patients had also received several conventional immunosuppressive and/or biologic agents. Seven patients experienced marked clinical improvement in the first 3 months after the onset of TCZ therapy. After a median follow-up of 15.5 [interquartile range-IQR: 12-24] months, 7 patients were asymptomatic. The median C-reactive protein decreased from 3.09 [IQR: 0.5-12] to 0.15 [IQR: 0.1-0.5] mg/dL (p=0.018), and median erythrocyte sedimentation rate from 40 [IQ range: 28-72] to 3 [IQR: 2-5] mm/1st hour (p=0.012). The median dose of prednisone was also tapered from 42.5 [IQR: 25-50] to 2.5 [IQR: 0-7.5] mg/day (p=0.011). However, TCZ had to be discontinued in 1 patient because she developed a systemic lupus erythematosus, and in another patient due to inefficiency. TCZ dose was reduced in a patient because of mild thrombocytopenia. CONCLUSIONS: TCZ appears to be effective in the management of patients with TA, in particular in patients refractory to corticosteroids and/or conventional immunosuppressive drugs.

OBJECTIVES: To assess the efficacy of other biologic therapies, different from infliximab (IFX) and adalimumab (ADA), in patients with Behçet's disease uveitis (BU). METHODS: Multicenter study of 124 patients with BU refractory to at least one standard immunosuppressive agent that required IFX or ADA therapy. Patients who had to be switched to another biologic agent due to inefficacy or intolerance to IFX or ADA or patient's decision were assessed. The main outcome measures were the degree of anterior and posterior chamber inflammation and macular thickness. RESULTS: Seven (5.6%) of 124 cases (4 women/3 men; mean age, 43 (range 28- 67) years; 12 affected eyes) were studied. Five of them had been initially treated with ADA and 2 with IFX. The other biologic agents used were golimumab (n=4), tocilizumab (n=2) and rituximab (n=1). The ocular pattern was panuveitis (n=4) or posterior uveitis (n=3). Uveitis was bilateral in 5 patients (71.4%). At baseline, anterior chamber and vitreous inflammation were present in 6 (50%) and 7 (58.3%) of the eyes. All the patients (12 eyes) had macular thickening (OCT>250µm) and 4 of them (7 eyes), cystoid macular edema (OCT>300 µm). Besides reduction anterior chamber and vitreous inflammation, we observed a reduction of OCT values, from 330.4±58.5 µm at the onset of the biological agent to 273±50 µm at month 12 (p=0.06). Six patients achieved a complete remission of uveitis. CONCLUSIONS: The vast majority of patients with BU refractory to standard immunosuppressive drugs are successfully controlled with ADA and/or IFX. Other biologic agents appear to be also useful.

OBJECTIVES: Data from a small series suggested that the Interleukin 1 beta (IL1ß) rs16944 polymorphism may be associated with severe renal involvement and persistent renal damage (renal sequelae) in Henoch-Schönlein purpura (HSP). To confirm this association, we assessed the largest cohort of Caucasian HSP patients ever considered for genetic studies. METHODS: 338 Spanish HSP patients and 635 sex and ethnically matched controls were recruited in this study. All patients were required to have had at least 6 months' follow-up. Patients and controls were genotyped for IL1ß rs16944 by TaqMan genotyping assay. RESULTS: No differences between IL1ß rs16944 genotype or allele frequencies were found either in the case/control study or when HSP patients were stratified according to the age at disease onset, presence of nephritis or gastrointestinal manifestations. Nevertheless, 4 (25%) of the 16 HSP patients who developed severe renal manifestations carried the TT genotype versus 29 (9%) of 322 who did not develop this complication (p=0.01, OR=5.48, 95% CI: 1.01-28.10). Accordingly, patients carrying the mutant T allele had an increased risk of developing severe nephropathy (p=0.016, OR=2.35, 95% CI: 1.09-5.07). Additionally, a significant increase of the TT genotype was observed in patients with persistent renal damage when compared with those patients without this complication (25% versus 8.6%, respectively; p=0.0035, OR=4.90, 95% CI: 1.26- 18.51). Moreover, renal sequelae were more common in patients carrying the mutant T allele (p=0.0076, OR=2.20, 95% CI: 1.17-4.14). CONCLUSIONS: Our results support that the IL1ß rs16944 polymorphism may be a potential marker of severe renal manifestations and renal sequelae in HSP.

OBJECTIVE: Cutaneous vasculitis (CV) encompasses a wide group of entities characterized by inflammation of skin blood vessels. The term single-organ vasculitis was recently coined by the 2012 Chapel Hill Consensus Conference (CHCC) to define vasculitis affecting a single organ. To our knowledge there are no published reports on single-organ cutaneous small vessel vasculitis (SoCSVV). Our aim was to characterize this entity from a wide series of patients with CV. METHODS: We analysed cases of SoCSVV from a series of 766 patients with CV from a single university referral centre. According to 2012 CHCC, the following conditions were required to define SoCSVV: (i) skin biopsy showing characteristic leucocytoclastic vasculitis and (ii) vasculitis limited to skin. RESULTS: We included 60 patients (26 women and 34 men) with a mean age of 56 years. The main precipitating factors for SoCSVV were drugs [26 patients (52%)] and previous infection [17 patients (34%)]. The main clinical manifestations were palpable purpura (81.7%) and fever (18.3%). The most frequent laboratory findings were leucocytosis and elevated ESR. Nearly one-quarter of patients with SoCSVV required pharmacological therapy. Corticosteroids (15%) and NSAIDs (13.3%) were the main agents prescribed. After a median follow-up of 4 months, complete recovery was observed in all the patients, although relapses occurred in 8% of patients. CONCLUSION: SoCSVV defined according to the 2012 CHCC may be considered a benign disease usually associated with drugs and/or a previous infection.

OBJECTIVE: The aim of this study was to assess the efficacy of anti-TNF-α therapy in refractory uveitis due to Behçet's disease (BD). METHODS: We performed a multicentre study of 124 patients with BD uveitis refractory to conventional treatment including high-dose corticosteroids and at least one standard immunosuppressive agent. Patients were treated for at least 12 months with infliximab (IFX) (3-5 mg/kg at 0, 2 and 6 weeks and then every 4-8 weeks) or adalimumab (ADA) (usually 40 mg every 2 weeks). The main outcome measures were degree of anterior and posterior chamber inflammation, visual acuity, macular thickness and immunosuppression load. RESULTS: Sixty-eight men and 56 women (221 affected eyes) were studied. The mean age was 38.6 years (s.d. 10.4). HLA-B51 was positive in 66.1% of patients and uveitis was bilateral in 78.2%. IFX was the first biologic agent in 77 cases (62%) and ADA was first in 47 (38%). In most cases anti-TNF-α drugs were used in combination with conventional immunosuppressive drugs. At the onset of anti-TNF-α therapy, anterior chamber and vitreous inflammation was observed in 57% and 64.4% of patients, respectively. In both conditions the damage decreased significantly after 1 year. At baseline, 50 patients (80 eyes) had macular thickening [optical coherence tomography (OCT) >250 µm] and 35 (49 eyes) had cystoid macular oedema (OCT>300 µm) that improved from 420 µm (s.d. 119.5) at baseline to 271 µm (s.d. 45.6) at month 12 (P < 0.01). The best-corrected visual acuity and the suppression load also showed significant improvement. After 1 year of follow-up, 67.7% of patients were inactive. Biologic therapy was well tolerated in most cases. CONCLUSION: Anti-TNF-α therapy is effective and relatively safe in refractory BD uveitis.

OBJECTIVES: The term cutaneous vasculitis (CV) includes a wide and heterogeneous group of entities. The American College of Rheumatology (ACR) established a set of criteria to classify vasculitis in 1990. Our aim was to further investigate into the applicability of these criteria for the classification of patients with primary CV. METHODS: We analysed a large and unselected series of patients with CV attended to a university referral centre from January 1976 to December 2011. Patients were classified according to the methodology and criteria proposed by the ACR1990 core data set. Patients were also classified according to the same ACR 1990 database as proposed by Michel et al. in 1992 to differentiate Henoch-Schönlein purpura (HSP) from hypersensitivity vasculitis (HV). RESULTS: We assessed 766 patients (346 women and 420 men) with a mean age of 34 years. Patients with cutaneous lesions in the setting of conditions different from primary CV were excluded. According to the 1990 ACR criteria, 405 (63.1%) of the 642 patients with primary CV were classified as having HSP and 230 (35.8%) as HV. However, 119 (18.5%) patients fulfilled the ACR 1990 criteria for both entities. In addition, 7 (1.1%) did not meet the ACR 1990 criteria for any of them and, therefore, they were considered as non-classified vasculitis. When patients with primary CV were tested for the Michel et al. criteria, 392 (61.1%) were classified as having HSP and 250 (38.9%) as HV. Frequent discordance between the ACR 1990 and the Michel et al. criteria was observed. It ranged between 18.4 and 21.7% for HSP and 32.2 to 38% for HV. CONCLUSIONS: According to our data, the ACR 1990 criteria are of limited value for the classification of patients with primary CV.

OBJECTIVES: Hypersensitivity vasculitis (HV) and Henoch-Schönlein purpura (HSP) are the most common entities included within the category of cutaneous vasculitis (CV). Palpable purpura and histological changes characterised by the presence of leukocytoclastic vasculitis are common in both conditions. Therefore, considerable overlap between them is often seen. It is especially true when the CV occurs in adults. To further establish clinical differences between these two conditions, in the present study we assessed the main clinical differences between HV and HSP in a wide and unselected series of adults with CV from a defined population. METHODS: We reviewed the clinical records of 297 consecutive adults (age >20 years) seen at a single centre between January 1975 and December 2012 that were classified as having HSP or HV according to the criteria proposed by Michel et al. (J Rheumatol 1992; 19: 721-8). RESULTS: Based on the inclusion criteria, 102 adult patients (71 men/31 women) were classified as HSP and 195 (104 men/91 women) as HV. The mean age was similar in both groups (55.8±16.5 years in HSP and 56.8±18.3 years in HV). Precipitating events, usually an upper respiratory tract infection and/or drug intake, were more frequently observed in HV. Both at the beginning of the disease and when the CV was established clinical manifestations were more frequent in patients with HSP than in those with HV. It was the case for gastrointestinal (57.4% vs. 6.8%; p<0.001), joint (51.5% vs. 36.6%; p=0.01) and renal involvement (86.3% vs. 18.3%; p<0.001). Corticosteroid (56.7% vs. 22%; p<0.001) and cytotoxic drug (19.4% vs. 3.2%; p<0.001) use was also more common in patients with HSP. After a median follow-up of 15.5 (interquartile range- IQR; 3-37) months in HSP and 4 (IQR; 2-12) months in HV, the outcome was better in HV than in HSP. In this regard, complete recovery (72.6% vs. 85.4%; p=0.01) was more commonly observed in HV while residual renal involvement (15.3% vs. 4.2%; p<0.001) was more common in HSP. The disease relapsed in 35.3% of patients with HSP and in 24.4% with HV (p=0.07). CONCLUSIONS: Our results confirm the claim that these two diseases presenting with similar cutaneous involvement are certainly two separate entities with greater systemic involvement and less favourable outcome in HSP.

OBJECTIVES: To evaluate the clinical response to Tocilizumab (TCZ) in three patients with non-infectious uveitis refractory to anti-TNF-α drugs. METHODS: Assessment of TCZ-treated patients with immune-mediated uveitis from two Spanish medical referral centers. Uveitis had been refractory to previous standard synthetic immunosuppressive drugs and at least one TNF-α inhibitor. A literature review of patients with immune-mediated uveitis treated with TCZ therapy was also conducted. RESULTS: 3 women (5 eyes) with uveitis refractory to conventional immunosuppressive therapy and at least one anti-TNF-α drug were treated with TCZ. The mean age of the patients was 48.6±16.1 (range 37-67) years. In two cases uveitis was bilateral and in the other unilateral. The underlying diseases were rheumatoid arthritis in one case and Behçet's disease in the other two cases. After a mean follow-up of 7.3±5.7 (range 1-12) months using TCZ therapy, all patients experienced ocular improvement. Also, in 3 eyes inactive intraocular inflammation was achieved. None of the patients had side effects during the period of treatment with this drug. A literature review disclosed that our observations are in keeping with other reports that showed good response to TCZ in 11 of 12 patients with immune-mediated uveitis refractory to other biologic agents. CONCLUSIONS: TCZ appears to be an effective and safe therapy for the management of patients with uveitis refractory to other biologic drugs.

OBJECTIVES: The aim of this paper is to assess the clinical response to golimumab (GLM) in patients with non-infectious uveitis from a single centre that had previously been treated with other anti-TNF-α drugs. METHODS: A retrospective chart review was carried out of patients with immune-mediated uveitis refractory to standard synthetic immunosuppressive drugs who were treated with GLM at Hospital Universitario Marqués de Valdecilla, Santander (Spain). Patients were included in this study if they had previously been treated with other anti-TNF-α drugs. A literature review of patients with immune-mediated uveitis undergoing GLM therapy was conducted. RESULTS: Three patients (2 men and 1 woman) were included in this study. Two of them were refractory to other anti-TNF-α drugs. The median age of patients was 26 years (range 20-42). Uveitis was bilateral in two patients. The underlying diseases were uveitis associated with HLA-B27 and psoriasis in one case and sarcoidosis in the other two cases. Improvement of the main ocular parameters following GLM therapy was achieved in all cases. After a median follow-up of 3 (range 1-9) months using GLM therapy, none of the patients had experienced new relapses of uveitis. None of them had side effects during treatment with this drug. A literature review disclosed that our observations were in keeping with other reports that showed good response to GLM in 13 of 16 patients with immune-mediated uveitis refractory to other biologic agents. CONCLUSIONS: Although the follow-up was too short in our series, GLM could be an effective and safe therapy for the management of patients with uveitis previously treated with other anti-TNF-α drugs.
