Lower limb enthesopathy in patients with psoriasis without clinical signs of arthropathy: a hospital-based case–control study

Background: Psoriasis is associated with a form of spondyloarthropathy in 10–30% of cases. A major feature of psoriatic arthritis is enthesitis. In some patients with psoriasis the presence of enthesitis could be underdiagnosed. Objective: To investigate the presence of lower limbs entheseal abnormalities in patients with chronic plaque psoriasis without signs and symptoms of psoriatic arthritis. Methods: Thirty patients with psoriasis and 30 controls underwent ultrasonographic evaluation of Achilles, quadriceps, patellar entheses and plantar aponeurosis. Ultrasonographic findings were scored according to the Glasgow Ultrasound Enthesitis Scoring System (GUESS). Results: Mean GUESS score was significantly higher in patients with psoriasis as compared with controls: 7.9 (0.6) vs 2.9 (0.3); p<0.0001. In particular, the thickness of all tendons examined was significant higher in cases than in controls (p<0.0001), as well as the number of enthesophytes in all sites examined. In both cases and controls, the GUESS score was directly correlated with age (r = 0.22; p = 0.008), body mass index (r = 0.23, p = 0.0067) and waist circumference (r = 0.17; p = 0.02). In contrast, the GUESS score was not correlated with the duration and severity of psoriasis according to the Psoriasis Area and Severity Index (r = 0.03; p = 0.8) and body surface area involvement (r = 0.07; p = 0.6). Conclusions: Entheseal abnormalities can be documented by ultrasonography in clinically asymptomatic patients with psoriasis. These findings could be related to a subclinical entheseal psoriatic inflammation. We suggest close follow-up of patients with psoriasis with entheseal abnormalities for early diagnosis of psoriatic arthritis.

Long-term anti-TNF therapy and the risk of serious infections in a cohort of patients with rheumatoid arthritis: Comparison of adalimumab, etanercept and infliximab in the GISEA registry

OBJECTIVE To evaluate the risk of serious infections (SIs) in RA patients receiving anti-TNF therapy on the basis of the data included in the GISEA register. METHODS The study involved 2769 adult patients with long-standing RA (mean age 53.2±13.4 years; mean disease duration 9.0±8.3 years) enrolled in the GISEA register, who had been treated for at least 6 months with TNF inhibitors or had discontinued therapy due to SI: 837 (30%) treated with infliximab (IFN), 802 (29%) with adalimumab (ADA), and 1130 (41%) with etanercept (ETN). RESULTS 176 patients had experienced at least one of the 226 Sis during the 9 years of treatment with an anti-TNF agent, an overall incidence of 31.8/1000 patient-years (95% CI 25.2-38.3): 23.7/1000 patient-years (95% CI 13.1-34.2) on ADA; 12.8/1000 patient-years (95% CI 6.3-19.4) on ETN and 65.1/1000 patient-years (95% CI 48.4-81.8) on IFN. The risk was higher in the first than in the second year of treatment, but this difference was not statistically significant (p=0.08) (38.9% of the SIs were recorded in the first 12 months of treatment). The risk of SI was significantly different among the three treatment groups (p<0.0001). Multivariate models confirmed that the use of steroids (p<0.046), concomitant DMARD treatment during anti-TNF therapy (p=0.004), advanced age at the start of anti-TNF treatment (p<0.0001), and the use of IFN or ADA rather than ETN (respectively p<0.0001 and p=0.023) were strong and statistically significant predictors of infection. CONCLUSIONS Anti-TNF therapy is associated with a small but significant risk of SI that is associated with the concomitant use of steroids, advanced age at the start of anti-TNF treatment, and the type of anti-TNF agent.

Most cases of primary salivary mucosa-associated lymphoid tissue lymphoma are associated either with Sjoegren syndrome or hepatitis C virus infection.

Salivary gland mucosa‐associated lymphoid tissue (MALT) lymphomas (SGML) are rare, as are data concerning their behaviour. We analysed clinical features at presentation, particularly the association with Sjoegren syndrome (SS) and hepatitis C virus (HCV) infection, and outcome in 33 cases of SGML diagnosed between March 1985 and April 2003. There were five males and 28 females, with a median age of 61 years. At presentation, 12/33 (36%) had multiple salivary glands or mucosal involvement and four had bone marrow infiltration. Ann Arbor stage was IE in 15 (46%), IIE in four (12%) and IV in 14 patients (42%). Fifteen patients had a history of SS (46%), two of other autoimmune diseases, seven of HCV infection. No case had both SS and HCV. Of the 29 treated patients, 17 received surgery or local radiotherapy; 69% achieved complete remission. Histological transformation occurred in four (12%). Five patients died (three of lymphoma, two of unrelated causes). The 5 year‐overall survival (OS), cause‐specific survival and progression‐free survival was 85 ± 8%, 94 ± 6% and 65 ± 10% respectively. Overall, the disease course was indolent, despite the advanced stage at diagnosis, and local therapy often appeared to be adequate. The only prognostic factors influencing OS were histological transformation and age. The close association of SGML with either autoimmune diseases or HCV infection in our series (73%) confirms their possible role in the pathogenesis of these lymphomas.

Risk factors for a first thrombotic event in antiphospholipid antibody carriers: a prospective multicentre follow-up study

Objectives To assess risk factors for a first thrombotic event in confirmed antiphospholipid (aPL) antibody carriers and to evaluate the efficacy of prophylactic treatments. Methods Inclusion criteria were age 18–65 years, no history of thrombosis and two consecutive positive aPL results. Demographic, laboratory and clinical parameters were collected at enrolment, once a year during the follow-up and at the time of the thrombotic event, whenever that occurred. Results 258 subjects were prospectively observed between October 2004 and October 2008. The mean±SD follow-up was 35.0±11.9 months (range 1–48). A first thrombotic event (9 venous, 4 arterial and 1 transient ischaemic attack) occurred in 14 subjects (5.4%, annual incidence rate 1.86%). Hypertension and lupus anticoagulant (LA) were significantly predictive of thrombosis (both at p<0.05) and thromboprophylaxis was significantly protective during high-risk periods (p<0.05) according to univariate analysis. Hypertension and LA were identified by multivariate logistic regression analysis as independent risk factors for thrombosis (HR 3.8, 95% CI 1.3 to 11.1, p<0.05, and HR 3.9, 95% CI 1.1 to 14, p<0.05, respectively). Conclusions Hypertension and LA are independent risk factors for thrombosis in aPL carriers. Thromboprophylaxis in these subjects should probably be limited to high-risk situations.

Risk factors for a first thrombotic event in antiphospholipid antibody carriers. A multicentre, retrospective follow-up study

Objectives: To asses risk factors for a first thrombotic event in antiphospholipid antibody (aPL) positive carriers and evaluate the efficacy of prophylactic treatments. Methods: Recruitment criteria were age 18–65 years, no history of thrombosis, positivity for lupus anticoagulant and/or IgG/IgM anticardiolipin antibody (aCL) on ⩾2 occasions at least 6 weeks apart. Demographic, laboratory and clinical parameters were collected at enrolment and at the time of the thrombotic event. Results: 370 patients/subjects (mean (SD) age 34 (9.9) years) were analysed retrospectively for a mean (SD) follow-up of 59.3 (45.5) months. Thirty patients (8.1%) developed a first thrombotic event during follow-up. Hypertension and medium/high levels of IgG aCL were identified by multivariate logistic regression analysis as independent risk factors for thrombosis. Thromboprophylaxis during high-risk and long-term periods was significantly protective. Conclusions: Hypertension or medium/high titres of IgG aCL are risk factors for a first thrombotic event in asymptomatic aPL carriers and primary prophylaxis is protective.

Longterm Retention of Tumor Necrosis Factor-α Inhibitor Therapy in a Large Italian Cohort of Patients with Rheumatoid Arthritis from the GISEA Registry: An Appraisal of Predictors

Objective. To evaluate 4-year retention rates of tumor necrosis factor-α (TNF-α) inhibitors adalimumab, etanercept, and infliximab among patients with longstanding rheumatoid arthritis (RA), as derived from an Italian national registry. Methods. The clinical records of 853 adult patients with RA in the GISEA (Gruppo Italiano Studio Early Arthritis) registry were prospectively analyzed to compare drug survival rates and the baseline factors that may predict adherence to therapy. Results. In 2003 and 2004, 324 patients started treatment with adalimumab, 311 with etanercept, and 218 with infliximab. After 4 years, the global retention rate of anti-TNF-α therapy was 42%. Etanercept survival (51.4%) was significantly better than that of infliximab (37.6%) or adalimumab (36.4%; p < 0.0001). Accordingly, the mean duration of therapy was significantly longer for etanercept (3.1 ± 2 yrs) than for adalimumab (2.6 ± 2 yrs) or infliximab (2.7 ± 2 yrs; p < 0.05). The use of concomitant disease-modifying antirheumatic drugs, mainly methotrexate, and the presence of comorbidities significantly predicted drug continuation (p < 0.01), whereas a high Disease Activity Score did not. Conclusion. The 4-year global drug survival of adalimumab, etanercept, and infliximab was lower than 50%, with etanercept having the best retention rate. The main positive predictor of adherence to anti-TNF-α therapy was the concomitant use of methotrexate. Our study provides further evidence that the real-life treatment of patients with RA may be different from that of randomized clinical trials.

Efficacy of methotrexate in the treatment of ankylosing spondylitis: a three-year open study.

Abstract: The aim of the study was to evaluate the efficacy of methotrexate treatment in patients with ankylosing spondylitis in a 3-year open trial. Seventeen patients, 14 men and three women (mean age 32.7 ± 8.9 years), suffering from ankylosing spondylitis and non-responders to treatment with sulphasalazine, were enrolled in our study. Sixteen of them were evaluable at the end of the study. Methotrexate (7.5–10 mg/week) was administered for 3 years. Efficacy was evaluated on the basis of clinical and laboratory variables, radiographic signs of disease progression and daily dosage of indomethacin. We obtained a good and relatively prompt clinical response except for peripheral arthritis and iridocyclitis; in fact, after 3 months of methotrexate treatment a significant amelioration of the following parameters was observed: visual analogue scale for the evaluation of both night pain and general well-being, Shober’s test, occiput-wall distance, fingertip to floor, erythrocyte sedimentation rate, C-reactive protein level and daily dose of indomethacin. A further improvement was obtained during the subsequent period. Radiographs of the spine and sacroiliac joints did not show any signs of disease progression. Side-effects were a transitory elevation of transaminases (four cases) and slight hypogammaglobulinaemia (one case). Methotrexate treatment may be useful in ankylosing spondylitis, but a combined treatment might be indicated for patients with peripheral arthritis.

Comparative effect of tacrolimus 0.1% ointment and clobetasol 0.05% ointment in patients with oral lichen planus.

BACKGROUND Oral lichen planus (OLP) is considered to be an autoimmune disease of unknown aetiology that affects the mucosae, especially the oral cavity. OBJECTIVE We compared tacrolimus 0.1% ointment and clobetasol 0.05% ointment for the treatment of OLP. PATIENTS AND METHODS A total of 32 patients (20 females and 12 males; all white, Italian origin, mean age of 43.6+/-18.4 years; 16 patients per treatment group) were treated with tacrolimus or clobetasol ointment for 4 weeks in a randomized, double-blind, clinical trial. Pain severity, burning sensation, and mucosal lesion extension were assessed using a four-point scale. RESULTS At the end of the treatment period, symptom scores were significantly lower in the tacrolimus group than in the clobetasol group. CONCLUSION The results of this study suggest that tacrolimus 0.1% ointment is more effective than clobetasol propionate 0.05% ointment in the treatment of OLP. However, other studies are needed to confirm the effectiveness of this treatment before it can be recommended for use in clinical practice.

Neutrophil migration, oxidative metabolism, and adhesion in elderly and young subjects

Objective. To evaluate neutrophil functions in the elderly.Methods. We investigated the PMN migration in vivo and PMN superoxide production and adhesion in response to a variety of compounds; PMN have been isolated both from blood and from a skin experimental exudate (obtained by Senns skin window technique) of 25 normal elderly and of 25 normal young control subjects.Results. No difference was found in PMN migration in vivo (62.9±21.3×106 and 65.5±9.1×106 PMN/cm2/24 hours in elderly and young subjects respectively), neither were different the adhesion under basal condition and after some stimuli and the superoxide production in basal condition and in response to STZ and PMA in two groups. In elderly subjects superoxide production, in response to fMLP, markedly resulted lower than in young controls both by circulating PMNs (3.6±2.7 and 9.3±3.3 nMOLES O2−/106 PMN respectively, p<0.0001) and by exudate PMNs (13.6±4.3 and 19.4±6 nMOLES O2−106 PMNs respectively, p<0.005).Conclusion. Many PMN functions in the elderly do not differ from young people, suggesting that the overall defense function of these cells is not affected by aging. The only parameter that we have found to be different between the two groups is the poor superoxide production after fMLP stimulus of PMNs. The stimulus- and function-specificity of this defect in PMNs from elderly subjects indicates the existence of a dysregulation of the signal transduction pathway distal to fMLP receptor and proximal to NADPH oxidase activation.

Safety of rofecoxib in subjects with a history of adverse cutaneous reactions to aspirin and/or non‐steroidal anti‐inflammatory drugs

Background Adverse reactions to non‐steroidal anti‐inflammatory drugs (NSAID)s are frequent, and the need to identify a safe alternative drug is a common problem in clinical practice.
