Objective To propose appropriate statements that drive the choice of biologic therapies in patients with rheumatoid arthritis (RA), factoring in their impact on the following issues: anti-drug antibody (ADAb) formation, suspicion and management of infections, lupus-like syndrome (LLS), effects on bone mass and sexual sphere, and relationship between RA and periodontal disease (PD). Methods An overview of existing evidence was undertaken by an expert panel on behalf of the Italian board for the TAilored BIOlogic therapy (ITABIO). Data were extracted from controlled trials, national registries, national health care databases, post-marketing surveys, and, when required by the paucity of controlled studies, from open-label clinical series. Anti-tumor necrosis factor (anti-TNF) and non-anti-TNF-targeted biologics approved for RA were investigated. Results ADAb formation is chiefly associated with anti-TNFs, and it is reduced by combination therapy with methotrexate. To date, ADAb titration is not advisable for clinical practice, and, in case of anti-TNF secondary failure, a non-anti-TNF biologic is indicated. LLS is observed in anti-TNF receivers and, in most cases, resolves without anti-TNF withdrawal. A non-anti-TNF biologic is advisable in patients experiencing LLS. Non-anti-TNFs demonstrated a low or absent infection risk and are preferable in patients with comorbidities. Due to their positive effects on bone mass, anti-TNFs are indicated in women at osteoporosis risk, whereas non-anti-TNF have been poorly investigated. The emerging evidence of the relationship between RA and PD and the effects on anti-TNF efficacy should lead clinicians to consider the periodontal status in RA patients. Anti-TNFs may exert a positive effect on fertility and sexuality, and clinicians should explore these aspects in RA patients. Conclusion The optimization of biologic therapies by taking into proper account the above issues would improve patient outcomes.

At baseline, patients received prednisone 1 mg/kg/day with rapid tapering and infliximab infusions (5 mg/kg) at weeks 0, 2, 6, and every 8 weeks thereafter. Nonresponders after the third infusion withdrew from the study. Primary outcome measures were visual acuity (VA) value improvement compared to baseline. Secondary outcome measures were proportion of patients with VA improvement from baseline; proportion of patients achieving disease remission; number of PU flare-ups; and incidence of adverse events.Results: At the final follow-up, mean right and left eye VA respectively increased from 0.57 ± 0.31 at baseline to 0.68 ± 0.33 (P = 0.048) and from 0.67 ± 0.28 to 0.76 ± 0.27 (P = 0.047). None of the patients had VA worsening and new onset ocular complications. A complete response of PU was recorded in 34/50 (68%) patients and partial response in 11/50 (22%). Five patients were nonresponders and withdrew from the study after the third infusion. A significant reduction of ocular attacks and of the proportion of patients with cystoid macular edema was observed. No differences in infliximab efficacy was recorded between patients with BD-associated and idiopathic PU. No serious adverse events occurred. The mean follow-up duration was 36.8 months.Conclusion: Long-term infliximab therapy was equally effective and safe with a significant VA gain in refractory BD-associated and idiopathic PU.Keywords: Behçet’s disease, idiopathic posterior uveitis, infliximab, posterior uveitis, visual acuity

Objective A multidisciplinary expert panel, the Italian board for the TAilored BIOlogic therapy (ITABIO), was constituted to formulate evidence-based decisional statements for the first-line tailored biologic therapy in patient with rheumatoid arthritis (RA), spondyloarthritis (SpA), and psoriatic arthritis (PsA). Methods Systematic review of the literature to identify English-language articles on the variables influencing the first-line biologic choice, including the efficacy and safety of the drug, the route of administration, the availability of response predictor biomarkers, the need of monotherapy, the patient socio-economic status, lifestyle, cultural level, personality, fertility and childbearing potential in women, the presence of comorbidities, the host-related risk factors for infection and latent tuberculosis infection (LTBI) reactivation, the cardiovascular (CV) risk, and costs. Results Some variables, including the patients’ preference, the indication for anti-TNF monotherapy in potential childbearing women, and the intravenous route with dose titration in obese subjects resulted valid for all the three rheumatic conditions. Further, evidence of a better cost-effectiveness profile for etanercept (ETN) and biosimilar infliximab (IFX) in RA was found. Any biologic may be employed in absence of choice driving factors in RA. Otherwise, a high infection risk or LTBI positivity drive the choice toward abatacept (ABA), tocilizumab (TCZ), or ETN. TCZ should be the first choice if monotherapy is required. High rheumatoid factor (RF) and anti-citrullinated protein antibodies (ACPA) titers should drive the choice toward TCZ or ABA, while in patients at high CVD risk anti-TNF choice, with preference for ETN, seems appropriate. Presence of anterior uveitis or inflammatory bowel disease drives the choice to monoclonal antibody anti-TNFs (MoAb anti-TNFs). In PsA, ustekinumab (UTK), and to a lesser extent ETN, represents the first choice in patients at high infection and TB risk. Anti-TNFs or UTK choice is guided by skin or articular disease severity, enthesitis, and dactylitis, whereas ETN should be preferred if metabolic syndrome or high CV risk complicate PsA. Conclusion Taking in account of multiple choice driving variables, first-line biologic therapy may be optimized in patients with RA, SpA, and PsA.

Fabrizio Cantini, Laura Niccoli, Emanuele Cassarà, Olga Kaloudi, Carlotta NanniniDivision of Rheumatology, Misericordia e Dolce Hospital of Prato, Prato,ItalyPurpose: The primary purpose of this study was to evaluate the proportion of psoriatic arthritis (PsA) patients maintaining clinical remission after adalimumab (ADA) dose reduction compared with patients with rheumatoid arthritis. Secondary purposes include evaluating the proportion of PsA patients who achieve remission, the duration of remission after ADA dose reduction, time to relapse, psoriasis course, and the frequency of adverse events at the end of follow-up.Methods: This was a single-center, prospective, follow-up, case-control study of 76 consecutive patients (35 females, 41 males; mean age 46 ± 10.2 years) who met the classification criteria for psoriatic arthritis and required anti-tumor necrosis factor therapy according to Group for Research and Assessment of Psoriasis and Psoriatic Arthritis recommendations. The 76 patients were compared with 55 patients (40 females, 15 males; mean age 50 ± 11.6 years) who satisfied the American College of Rheumatology criteria for rheumatoid arthritis and received the same treatment. Case patients and controls were recruited from January 2008 to December 2010. At baseline, PsA patients and controls received 40 mg of ADA every other week, usually with methotrexate (10 to 20 mg/weekly). In the presence of clinical remission, ADA dose was reduced to 40 mg every 4 weeks in both groups.Results: Fifty-three of the 76 (69.7%) PsA patients and 17 of the 55 (30.9%) rheumatoid arthritis (P < 0.019) controls achieved remission after a mean time of 5.1 ± 1.2 and 6.3 ± 1.6 months, respectively (P = nonsignificant). After halving the dose of ADA, 47 of the 53 (88.6%) PsA patients and three of the 17 (17.6%) controls maintained remission (P = 0.016) over a mean follow-up period of 28.9 ± 8.4 and 24.2 ± 6.4 months, respectively. No significant changes in Psoriatic Arthritis Severity Index scores were observed. The mean time to relapse was 8.3 ± 3.4 months in six case patients and 7.2 ± 4.2 in 14 controls (P = not significant). No serious adverse events occurred in either group.Conclusion: Clinical remission is possible in a high percentage of patients with early PsA receiving ADA. Such remission is maintained in a high proportion of subjects after ADA dose halving, with relevant advantages in terms of patient compliance, drug-exposure risk, and economic burden.Keywords: psoriatic arthritis, anti-TNF, adalimumab, remission, dose reduction

BackgroundCurrently, assessment of dermal thickness in systemic sclerosis (SSc) is performed by palpation and assessment using the modified Rodnan skin score (mRSS).ObjectiveTo verify whether high frequency ultrasound (US) may be a reliable and a reproducible method to measure digital dermal thickness.MethodsIn 70 patients with SSc, skin thickness was evaluated with US by 2 observers at 2 different sites on the second digit of the dominant limb to determine the interobserver variability. Patients and controls were examined twice by the first observer for intraobserver variability. Patients were divided into three subgroups according to the phase of the disease (oedematous, fibrotic or atrophic).ResultsAt both examined areas, US showed a significant dermal thickening (pConclusionsUS is a reliable tool giving reproducible results, and is able to detect digital dermal thickening in SSc.

OBJECTIVE Advanced glycation endproducts (AGEs), including Nepsilon-(carboxymethyl)lysine-protein adducts (CML) are involved in micro/macrovascular changes and are co-localized with adhesion molecules in inflamed tissues. Serum levels of CML were investigated in systemic sclerosis (SSc) characterized by microvascular modifications and correlated with indices of micro/macrovascular damage. METHODS In 66 SSc patients (limited SSc, n = 55; diffuse SSc, n = 11) and 20 controls, CML serum levels were measured by enzyme-linked immunosorbent assay. Nailfold capillaroscopy, intima-media thickness (IMT) and the ankle-brachial index (ABI) were also recorded, to characterize micro/macrovascular involvement. RESULTS CML levels were significantly higher in SSc (79.2 +/- 39 mg/ml vs 49.6 +/- 26.1 mg/ml, mean +/- s.d.; P
