American College of Rheumatology Guidance Statement for Diagnosis and Management of VEXAS Developed by the International VEXAS Working Group Expert Panel.

OBJECTIVE: Vacuoles E1 enzyme X-linked autoinflammatory somatic syndrome (VEXAS) is a recently identified rare genetic disorder associated with somatic mutations in the UBA1 gene. VEXAS presents with a combination of inflammatory and hematologic manifestations, leading to increased morbidity and mortality. METHODS: Given the variability in disease presentation and the limited number of studies to date, no clinical documents currently exist to provide guidance to health care providers about the management of VEXAS. To address this gap, we formed an international multidisciplinary panel of VEXAS experts. RESULTS: Through formalized meetings and a voting process, the group developed consensus clinical guidance considerations for the management of VEXAS. These considerations offer practical advice on several key topics: (1) clinical features of VEXAS, (2) UBA1 screening methods, (3) the diagnosis of myelodysplastic syndromes (MDSs) in patients with VEXAS, and (4) prognosis and management. The aim is to provide expert guidance on which patients to test, how to test for VEXAS, how to approach MDS in the context of VEXAS, and considerations for management. CONCLUSION: This work marks the first formal international consensus guidance for VEXAS and is intended to be used as a resource for clinicians seeking to understand the disease and its management.

Chronic periaortitis and HLA-DRB1*03: another clue to an autoimmune origin.

OBJECTIVE: Patients with chronic periaortitis (CP) often show clinical and laboratory findings of a systemic autoimmune disorder. The aim of the present study was to investigate the role of the HLA system in CP. METHODS: Low-resolution genotyping for HLA-A, HLA-B, and HLA-DRB1 loci and genotyping of TNFA(-238)A/G and TNFA(-308)A/G single nucleotide polymorphisms were performed in 35 consecutive patients with CP and 350 healthy controls. RESULTS: The HLA-DRB1*03 allele frequency was strikingly higher in patients with CP than in controls (24.28% versus 9.14%; chi(2) = 15.50, P = 0.000084, corrected P [P(corr)] = 0.0012, odds ratio [OR] 3.187, 95% confidence interval [95% CI] 1.74-5.83); the HLA-B*08 allele frequency was also higher in patients than in controls (17.14% versus 6.28%; chi(2)=11.12, P = 0.0008, P(corr) = 0.0269, OR 3.085, 95% CI 1.54-6.16). The A*01 allele frequency was significantly different (P = 0.0463), but the statistical significance was lost after correction for multiple testing (P(corr) = 0.5088). TNFA(-238)A allele and TNFA(-308)A allele frequencies were not significantly different (P = 0.512 and P = 0.445, respectively). Comparison of the main clinical and laboratory findings suggestive of a systemic autoimmune disease (e.g., acute-phase reactants, constitutional symptoms, other autoimmune diseases associated with CP) between the HLA-DRB1*03-positive and the HLA-DRB1*03-negative patients showed that the former group had significantly higher levels of C-reactive protein (P = 0.045) at disease onset, although this difference was not statistically significant after correction for multiple tests (P(corr) = 0.369). CONCLUSION: The HLA system plays a role in susceptibility to CP. The strong association between CP and HLA-DRB1*03, an allele linked to a wide range of autoimmune conditions, further supports the view that CP may represent a clinical manifestation of an autoimmune disease.

Retroperitoneal fibrosis.

Retroperitoneal fibrosis encompasses a range of diseases characterised by the presence of a fibro-inflammatory tissue, which usually surrounds the abdominal aorta and the iliac arteries and extends into the retroperitoneum to envelop neighbouring structures--eg, ureters. Retroperitoneal fibrosis is generally idiopathic, but can also be secondary to the use of certain drugs, malignant diseases, infections, and surgery. Idiopathic disease was thought to result from a local inflammatory reaction to antigens in the atherosclerotic plaques of the abdominal aorta, but clinicolaboratory findings--namely, the presence of constitutional symptoms and the high concentrations of acute-phase reactants--and the frequent association of the disease with autoimmune diseases that involve other organs suggest that it might be a manifestation of a systemic autoimmune or inflammatory disease. Steroids are normally used to treat idiopathic retroperitoneal fibrosis, although other options--eg, immunosuppressants, tamoxifen--are available. The outlook is usually good, but, if not appropriately diagnosed or treated, the disease can cause severe complications, such as end-stage renal failure. Here, we review the different aspects of retroperitoneal fibrosis, focusing on idiopathic retroperitoneal fibrosis and on the differential diagnosis associated with the secondary forms.

Interleukin-10 promoter polymorphisms in giant cell arteritis.

OBJECTIVE: To investigate potential associations between interleukin-10 (IL-10) promoter polymorphisms and susceptibility to, and clinical features of, giant cell arteritis (GCA). METHODS: A total of 140 patients with biopsy-proven GCA who were residents of Reggio Emilia, Italy, and 200 population-based controls from the same geographic area were genotyped for promoter polymorphisms of the IL-10 gene, by molecular methods. The patients were subgrouped according to the presence or absence of polymyalgia rheumatica (PMR) and ischemic complications (any or all of the following: vision loss, jaw claudication, cerebrovascular accidents, or aortic arch syndrome). RESULTS: The distribution of the C/A 592 genotype differed significantly between the GCA patients and the controls (P(corr) = 0.003). Carriers of the A592 allele (A/A or C/A) were significantly more frequent among the GCA patients than among the controls (P(corr) = 0.004, odds ratio [OR] 2.0 [95% confidence interval (95% CI) 1.3-3.1]). Homozygosity for the A592 allele was significantly more frequent among the GCA patients than among the controls (P(corr) = 0.002, OR 3.4 [95% CI 1.6-7.2]). The distribution of the A/G 1082 genotype was similar in GCA patients and controls. In the haplotype analysis, the frequency of the ATA haplotype was significantly higher in GCA patients than in the controls (P = 0.0001), whereas the frequencies of the ACC and GTA haplotypes were significantly lower (P = 0.0001 for both comparisons). No significant associations were found for comparisons of GCA patients with and those without PMR or GCA patients with and those without ischemic complications. CONCLUSION: Our findings show that the -592 C/A promoter polymorphism of the IL-10 gene is associated with susceptibility to GCA.

New approaches in the treatment of Adamantiades-Behçet's disease.

PURPOSE OF REVIEW: To update clinicians on the recent advances in the treatment of Adamantiades-Behçet's disease. RECENT FINDINGS: Interferon-alpha-2a and infliximab have proved able to induce prompt remission in the vast majority of Adamantiades-Behçet's patients with DMARD-resistant uveoretinitis. Efficacy of interferon-alpha-2a has also been reported for mucocutaneous lesions, arthritis, and (more anecdotally) for neuro-Behçet, while results from small case series suggest that infliximab is beneficial for mucocutaneous lesions and (more anecdotally) for arthritis and gastro-intestinal manifestations. Two cases of neuro-Behçet treated with infliximab showed a complete resolution. Finally, in a randomized controlled trial of patients with mucocutaneous, arthritic manifestations, or both, etanercept effectively suppressed mucocutaneous lesions.A different approach is tolerization by oral administration of the 336-351 peptide of the human heat shock protein 60 (thought to have a pathogenic role in Adamantiades-Behçet's disease-associated uveitis), linked to recombinant cholera B-toxin B-subunit. Preliminary results have shown that tolerization is safe and effective in preventing relapses of uveitis. SUMMARY: Biologic agents have proved effective in patients resistant to conventional treatment. However, disease subsets characterized by severe morbidity and mortality such as vasculo-Behçet and neuro-Behçet still pose major therapeutic challenges. Further studies are needed to devise better treatment strategies for severe Adamantiades-Behçet's disease.

Relationship between interleukin 6 promoter polymorphism at position -174, IL-6 serum levels, and the risk of relapse/recurrence in polymyalgia rheumatica.

OBJECTIVE: To assess the role of -174 G/C promoter polymorphism of interleukin 6 (IL-6) in the susceptibility to polymyalgia rheumatica (PMR). We also investigated whether this polymorphism modulates the circulating level of IL-6 and the risk of relapse/recurrence in a series of patients with PMR followed up prospectively. METHODS: A prospective study of 112 consecutive, untreated patients with isolated PMR (i.e., without evidence of giant cell arteritis) who were followed up for at least 24 months. This cohort represented all patients diagnosed over a 5-year period in one Italian rheumatological secondary referral center. Patients were monitored for clinical signs/symptoms and acute-phase reactants. All PMR patients and 112 population-based controls from the same geographic area were genotyped for IL-6 polymorphism at position -174 by molecular methods. IL-6 serum levels were measured in 67 PMR patients and 43 population-based controls. RESULTS: The distribution of the G/C 174 genotype was similar in PMR patients and controls. No significant associations with IL-6 promoter polymorphism at position -174 were found when PMR patients with and without relapse/recurrence were compared. Controls homozygous for the C allele had higher serum IL-6 levels than the carriers of the G allele (4.5 +/- 3.7 pg/ml vs 1.8 +/- 2.1 pg/ml, p = 0.01). Patients homozygous for the allele C had significantly higher values of IL-6 during followup than patients carrying GC or GG genotypes. CC homozygosity was significantly more frequent in patients with persistently elevated levels of IL-6 than in those without. The presence of persistently elevated IL-6 levels, but not the CC genotype, was associated with an increased frequency of relapse/recurrence. CONCLUSION: Our findings show that the 174 G/C promoter IL-6 polymorphism is not implicated in susceptibility to PMR. However, CC genotype characterized PMR patients with persistently elevated levels of IL-6 who are at higher risk of developing relapse/recurrence. A genetically modulated pattern of IL-6 production could affect the longterm outcome of patients with PMR.

Tumor necrosis factor-alpha protects synovial cells from nitric oxide induced apoptosis through phosphoinositide 3-kinase Akt signal transduction.

OBJECTIVE: To investigate the anti-apoptotic role of tumor necrosis factor-a (TNF-a) and its signaling pathways in cultured human fibroblast-like synoviocytes (FLS) from patients with rheumatoid arthritis. METHODS: FLS were cultured in Dulbecco's modified Eagle's medium. Apoptotic cells were identified by TUNEL assay and Hoechst staining. Cell viability was determined by the MTT method. Expression of phospho-Akt and phospho-BAD was measured by Western blotting. RESULTS: A 24-h TNF-a treatment prevented FLS apoptosis induced by nitric oxide (NO) donor sodium nitroprusside dihydrate (SNP), achieving 70% protection. At 1-10 ng x ml-1 concentrations, TNF-a induced phosphorylation of Akt and BAD in a time and concentration-dependent manner. This effect was blocked by treatment with both LY294002 and nuclear factor-kB inhibitor pyrrolidine-dithiocarbamate. CONCLUSION: TNF-a has an anti-apoptotic effect in human FLS. Activation of Akt and BAD may have an important role in this process.

Systemic lupus erythematosus (SLE) in Italy: an Italian prevalence study based on a two-step strategy in an area of Florence (Scandicci-Le Signe).

BACKGROUND: The goal was to ascertain the prevalence of SLE in the population over 18 years of age in the Scandicci-Le Signe area of Florence, Italy, based on the records of general practitioners (GPs). MATERIAL/METHODS: Twenty GPs screened 32,521 patients by administering the Lupus Screening Questionnaire (LQS) and found 30 patients with suspected or definite diagnosis of SLE. To confirm the diagnoses the patients were referred to a rheumatologist who conducted routine examinations and assessed antinuclear antibodies and SLE activity (ECLAM score). RESULTS: Total population >18 years of age in the three municipalities was 71,204 persons, with 42,474 in Scandicci, 15,368 in Lastra a Signa, and 13,362 in Signa. In 23/30 patients diagnosed with SLE the diagnosis was confirmed. Eleven of the 23 SLE patients were from Scandicci and 6 each from Lastra a Signa and Signa. An overall estimated prevalence of SLE of 71/100,000 (1/1408; 95% CI=49, 92) was found in the total population of the three municipalities. Scandicci (95% CI=42, 121) had a rate of 81/100.000, while Lastra a Signa (95% CI=32, 92) and Signa (95% CI=36, 94) had estimated rates of 62/100,000 and 65/100,000, respectively. Medium ECLAM score was 4.68+/-1.81 SD. CONCLUSIONS: This is the first epidemiological study on SLE prevalence in Italy. The prevalence and point prevalence are similar to other European studies. The LQS was also confirmed as an easy and reliable tool to assess SLE diagnosis in the Italian population.

Positron emission tomography (PET): evaluation of chronic periaortitis.

OBJECTIVE: To evaluate the presence and extent of large-vessel inflammation in patients with chronic periaortitis (CP) using (18)F-fluorodeoxyglucose-positron emission tomography (FDG-PET). METHODS: A consecutive case series consisting of 7 patients with CP seen over a 3-year period and a control group of 14 patients with malignancy were evaluated with FDG-PET. For every case we selected 2 age- and sex-matched controls who underwent PET imaging for malignancy. The diagnosis of CP was made by means of computed tomography. PET imaging was performed at diagnosis before therapy was started. Measurement of vascular uptake was graded using a 4-point semiquantitative scale. RESULTS: All patients had evidence of grade 2+ or 3+ vascular uptake in the abdominal aorta and/or iliac artery. No controls showed vascular uptake greater than 1+. Vascular uptake in the thoracic aorta and/or in its branches was seen in 3 (43%) of 7 patients. Vascular uptake in abdominal aorta and/or iliac artery was observed in patients with CP but not in controls (100% versus 0%). There was also a significantly more frequent FDG uptake in the large thoracic arteries in case-patients compared with controls (43% versus 0%; P = 0.03). CONCLUSION: FDG-PET scan shows in patients with CP the presence of a large-vessel vasculitis involving abdominal aorta and common iliac arteries, which in some patients is also extended to thoracic aorta and/or its branches.

Risk factors for visual loss in an Italian population-based cohort of patients with giant cell arteritis.

OBJECTIVE: To evaluate the frequency of visual manifestations at presentation in an Italian population-based cohort of patients with biopsy-proven giant cell arteritis (GCA), and to investigate predictors for the development of permanent visual loss. METHODS: We identified 136 Reggio Emilia (Italy) residents with biopsy-proven GCA diagnosed between 1986 and 2002. Medical records of these 136 patients were reviewed, and demographic, clinical, and laboratory data were collected.Multivariate analysis with multiple logistic regression models was performed to identify the best predictors of visual loss. RESULTS: Visual manifestations developed in 41 patients (30.1%). Partial or total visual loss was observed in 26 patients (19.1%). Anterior ischemic optic neuropathy was seen in 24 patients, and 2 patients had central retinal artery occlusion. Unilateral vision loss occurred in 19 patients, and bilateral visual loss in 7. In 25 patients, visual loss developed before glucocorticoid therapy for GCA was started. The age at disease onset was significantly higher in patients with permanent visual loss compared with those without it. The frequency of systemic signs/symptoms and erythrocyte sedimentation rate (ESR) and C-reactive protein values at diagnosis were significantly lower in patients with permanent visual loss. By multivariate logistic regression, the only statistically significant predictor for the development of permanent visual loss was the absence of high levels of ESR at diagnosis (tertile 2: Odds ratio [OR] 0.08; tertile 3: OR 0.11). Other predictors included in the model were the absence of systemic manifestations (OR 0.24), an older age at disease diagnosis (quintile 5: OR 5.60), and the presence of an elevated platelet count at diagnosis (OR 4.99), however they were only of borderline statistical significance. CONCLUSION: The proportion of Italian patients with GCA that developed visual loss was similar to that reported from other countries. The patients with low inflammatory response had a higher risk of visual loss.

Acute-phase reactants and the risk of relapse/recurrence in polymyalgia rheumatica: a prospective followup study.

OBJECTIVE: To determine laboratory parameters that may be useful in identifying polymyalgia rheumatica (PMR) patients who require long-term corticosteroid therapy. METHODS: A prospective followup study of 94 consecutive untreated patients with PMR were assessed for relapse/recurrence for a mean of 39 months. This cohort represented all the patients diagnosed over a 4-year period in 2 Italian secondary referral centers. Patients were monitored for clinical signs and symptoms, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and serum interleukin-6 (IL-6). IL-6 levels were also measured in 43 controls matched to the patients for age and sex. RESULTS: The ESR was elevated in 91.5% of the patients prior to therapy initiation, as were CRP in 98.9% and serum IL-6 in 92.6%. Forty-seven (50.0%) patients had at least 1 relapse/recurrence during the followup period and 24 (25.5%) had at least 2. After 4 weeks of prednisone therapy, ESR was elevated in 13.2% patients, CRP in 41.9%, and serum IL-6 in 37.2%. IL-6 levels remained persistently elevated in 9.9% and CRP in 8.7% of patients during the first year of followup, whereas no patient had persistently elevated ESR. Persistently elevated CRP and IL-6 levels were significantly associated with an increased risk of relapse/recurrence. In particular, patients with persistently elevated levels of IL-6 during the first year of therapy had the highest relative risk. CONCLUSION: Despite the control of clinical symptoms, corticosteroids do not adequately control the inflammatory process in a subset of patients with PMR who have persistently elevated levels of CRP and IL-6 and who have a higher risk of relapsing.

Are steroids alone sufficient for the treatment of giant cell arteritis?

Glucocorticosteroids are the cornerstone of treatment of giant cell arteritis. An initial dose of prednisone or its equivalent of at least 40-60mg per day as single or divided dose is usually adequate. Glucocorticosteroids may prevent, but usually do not reverse, visual loss. A treatment course of 1-2 years is often required. Some patients, however, have a more chronic-relapsing course and may require low doses of glucocorticosteroids for several years. Glucocorticosteroid-related adverse events are common. In studies on immunosuppressant agents, methotrexate has been used as a glucocorticosteroid-sparing drug with conflicting results. This drug may, however, be given to patients who need high doses of glucocorticosteroids to control active disease and who have serious side effects. A recent pilot study found that infliximab was efficacious in patients with glucocorticosteroid-resistant giant cell arteritis. However, randomized controlled trials are required to define the role of anti-tumor necrosis factor-alpha agents in the treatment of giant cell arteritis. Finally, low-dose aspirin has been shown in a recent retrospective study to decrease the rate of cranial ischemic complications secondary to giant cell arteritis. It is conceivable that the definition of different patterns of inflammation in giant cell arteritis in the future might facilitate the design of differentiated therapeutic approaches.

Interleukin-6 promoter polymorphism at position -174 in giant cell arteritis.

OBJECTIVE: To investigate potential associations between the -174 G/C interleukin-6 (IL-6) promoter polymorphism and susceptibility to and clinical features of giant cell arteritis (GCA), particularly in patients with or without polymyalgia rheumatica (PMR) and with or without ischemic complications. METHODS: One hundred and twenty-six patients with biopsy-proven GCA who were residents in Reggio Emilia, Italy, and 112 population-based controls from the same geographic area were genotyped for IL-6 polymorphism at position -174 by molecular methods. Patients were divided in subgroups according to presence or absence of PMR and ischemic complications (visual loss, jaw claudication, cerebrovascular accidents, aortic arch syndrome). RESULTS: Distribution of the G/C 174 genotype was similar in patients with GCA and controls. No significant associations with the IL-6 promoter polymorphism at position -174 were found when GCA patients with or without PMR or with or without ischemic complications were compared. Further, IL-6 genotypes did not significantly affect levels of C-reactive protein or other inflammatory markers at diagnosis. CONCLUSION: Our findings show that the 174 G/C promoter IL-6 polymorphism does not seem to be implicated in susceptibility to and clinical expression of GCA.

Prednisone plus methotrexate for polymyalgia rheumatica: a randomized, double-blind, placebo-controlled trial.

BACKGROUND: Steroids are the standard treatment for polymyalgia rheumatica. The efficacy of the candidate drug methotrexate has not yet been demonstrated in controlled studies. OBJECTIVE: To compare the efficacy and safety of prednisone plus methotrexate and prednisone alone in patients with polymyalgia rheumatica. DESIGN: Multicenter randomized, double-blind, placebo-controlled trial. SETTING: 5 Italian rheumatology clinics. PATIENTS: 72 patients with newly diagnosed polymyalgia rheumatica. MEASUREMENTS: The proportion of patients no longer taking prednisone, the number of flare-ups, and the cumulative prednisone dose after 76 weeks. INTERVENTION: Prednisone dosage (25 mg/d) was tapered to 0 mg/d within 24 weeks and was adjusted if flare-ups occurred. Oral methotrexate (10 mg) or placebo, with folinic acid supplementation (7.5 mg), was given weekly for 48 weeks. RESULTS: Twenty-eight of 32 patients in the methotrexate group and 16 of 30 patients in the placebo group were no longer taking prednisone at 76 weeks (P = 0.003). The risk difference was 34 percentage points (95% CI, 11 to 53 percentage points). Similar results were obtained after adjustment for C-reactive protein level and duration of symptoms in a multivariate model. Fifteen of 32 patients in the methotrexate group and 22 of 30 patients in the placebo group had at least 1 flare-up by the end of follow-up (P = 0.04). The median prednisone dose was 2.1 g in the methotrexate group and 2.97 g in the placebo group (P = 0.03). The rate and severity of adverse events were similar. LIMITATIONS: Follow-up was short, and a high dose of folinic acid and a relatively high starting dosage of prednisone were used. Ten of 72 patients (14%) discontinued treatment or were lost to follow-up. CONCLUSIONS: Prednisone plus methotrexate is associated with shorter prednisone treatment and steroid sparing. It may be useful in patients at high risk for steroid-related toxicity.
