To assess efficacy, safety, pharmacokinetics, and immunogenicity of pegloticase plus methotrexate (MTX) versus pegloticase plus placebo cotreatment for uncontrolled gout in a randomized, placebo-controlled, double-blind trial.This study included adults with uncontrolled gout, defined as serum urate ≥7 mg/dl, oral urate-lowering therapy failure or intolerance, and presence of ongoing gout symptoms including ≥1 tophus, ≥2 flares in the past 12 months, or gouty arthritis. Key exclusion criteria included MTX contraindication, current immunosuppressant use, G6PDH deficiency, and estimated glomerular filtration rate40 ml/minute/1.73 mA total of 152 patients were randomized, 100 to receive pegloticase plus MTX, 52 to receive pegloticase plus placebo. Significantly higher treatment response occurred during month 6 in the MTX group versus the placebo group (71.0% [71 of 100 patients] versus 38.5% [20 of 52 patients], respectively; between-group difference 32.3% [95% confidence interval 16.3%, 48.3%]) (P 0.0001 for between-group difference). During the first 6 months of pegloticase plus MTX or pegloticase plus placebo treatment, 78 (81.3%) of 96 MTX patients versus 47 (95.9%) of 49 placebo patients experienced ≥1 adverse event (AE), most commonly gout flare (64 [66.7%] of 96 MTX patients and 34 [69.4%] of 49 placebo patients). Reports of AEs and serious AEs were comparable between groups, but the infusion reaction rate was considerably lower with MTX cotherapy (4.2% [4 of 96 MTX patients, including 1 patient who had anaphylaxis]) than with placebo cotherapy (30.6% [15 of 49 placebo patients, 0 who had anaphylaxis]) (P 0.001). Antidrug antibody positivity was also lower in the MTX group.MTX cotherapy markedly increased pegloticase response rate over placebo (71.0% versus 38.5%) during month 6 with no new safety signals. These findings verify higher treatment response rate, lower infusion reaction incidence, and lower immunogenicity when pegloticase is coadministered with MTX.

Introduction Effective communication between patients with psoriatic arthritis (PsA) and their physicians is important for optimizing treatment outcomes. We assessed the quality of patient–physician communication in terms of awareness and impact of PsA symptoms, their levels of satisfaction, and their perceptions of communications. Methods A global online survey was conducted by The Harris Poll in adult patients with PsA and physicians managing patients with PsA in eight countries. Participating physicians were either rheumatologists or dermatologists seeing ≥ 10 and ≥ 5 patients with PsA per month, respectively. Patient and physician groups were unmatched. Patient–physician communication was assessed with 35–60 questions regarding discussion topics during consultations, levels of satisfaction with communication, and specific communication issues. Results A total of 1286 patients with PsA (983 and 303 whose primary treating physician was a rheumatologist or dermatologist, respectively) and 1553 physicians (795 rheumatologists and 758 dermatologists) completed the survey. Regardless of whether they were primarily treated by a rheumatologist or dermatologist, most patients reported a social (84% and 81%, respectively) or work (81% and 80%, respectively) impact of PsA, and a major/moderate negative impact on their physical activity levels (79% and 74%, respectively) or emotional/mental wellbeing (69% and 68%, respectively). Physician responses were generally consistent with this; however, physicians often appeared to under-recognize the extent to which PsA affects patients. Most (≥ 85%) patients and physicians were very/somewhat satisfied with their patient–physician communication, and most (≥ 86%) patients were comfortable raising their concerns/fears with their physician. However, > 40% of patients were identified as being at risk of suboptimal communication. These patients were significantly less likely to report their PsA symptoms even when asked, were less comfortable discussing the impacts of PsA with their physician, and were more likely to experience major/moderate impacts of PsA on their health-related quality of life (HRQoL). Conclusions Physicians often underestimate the impacts of PsA, compared with patients, and some patients may be at risk of suboptimal communication with their attending physician, which may worsen the HRQoL impacts of PsA. These findings highlight a need for ways to improve communication between patients with PsA and their healthcare providers.

To effectively treat PsA, it is important that doctors and patients communicate well. We used a survey to ask patients with PsA and doctors from around the world about their communications about PsA. We also asked how PsA affects patients’ quality of life. In total, 1286 patients and 1553 doctors took the survey. Most patients said that PsA affected their social and work lives. Similarly, PsA had a negative impact on physical activity and on emotional and/or mental wellbeing in most patients who answered the survey. Doctors answered similarly, but they were generally less likely to recognize how severely PsA can impact patients, compared with patients themselves. Most patients and doctors were happy with their patient–doctor communication, and most patients felt comfortable talking about their worries and/or fears with their doctor. However, some patients (about four out of 10) felt that communication with their doctors was not good; these patients were less likely/comfortable to talk about their PsA symptoms and the impacts of PsA with their doctor. PsA was also more likely to negatively impact these patients’ quality of life. This survey shows that it is important to find ways to improve communication between patients with PsA and their doctors.

Background Pegloticase is a recombinant porcine-like uricase enzyme that is FDA-approved for the treatment of chronic refractory gout in adults. Some patients receiving pegloticase develop anti-drug antibodies, which leads to both loss of pegloticase efficacy and an increased risk for infusion reactions. In the pivotal trials, all patients received pre-infusion medications before each pegloticase dose, including intravenous (IV) hydrocortisone. In clinical practice, many clinicians use methylprednisolone for pre-infusion therapy with pegloticase; however, the efficacy of methylprednisolone compared with hydrocortisone as a pre-infusion medication for pegloticase has not been established. Objective The aim of this study was to compare the efficacy of methylprednisolone versus hydrocortisone as a pre-infusion medication for pegloticase. Methods Data were retrospectively collected from 92 qualifying patients treated with pegloticase and administered pre-infusion prophylaxis with either intravenous hydrocortisone or methylprednisolone. Patient demographics, steroid type and dose, duration of pegloticase therapy, overall number of infusions, and number of infusion reactions were assessed. Results Patients treated with methylprednisolone as a pre-infusion medication received on average 8.5 pegloticase infusions versus 4.9 infusions for patients who were treated with hydrocortisone (p
