Abstract
BackgroundConventional synthetic disease modifying anti-rheumatic drugs (csDMARDs) are the cornerstone first-line treatment in psoriatic arthritis (PsA), although there is a paucity of evidence for the effectiveness of csDMARDs and especially their combination. Assessing the efficacy and safety of combinations of csDMARDs compared with csDMARD monotherapy has been prioritized on the EULAR research agenda. We hypothesized that combining csDMARDs might be more effective than csDMARD monotherapy.ObjectivesWe aimed to investigate whether a combination of methotrexate (MTX) and leflunomide (LEF) is superior to MTX monotherapy on improvement in disease activity in patients with PsA.MethodsPatients with a clinical diagnosis of PsA and active disease (≥2 swollen joints) were included in this randomised, placebo-controlled, double-blind trial. Patients were randomised (1:1) to MTX plus LEF or MTX plus placebo. Patients received MTX 15 mg/week for four weeks and thereafter 25 mg/week, combined with two LEF 10 mg tablets or two placebo tablets daily. The primary outcome was the difference between the MTX plus LEF group and the MTX plus placebo group on the psoriatic arthritis disease activity score (PASDAS) at week 16 adjusted for baseline PASDAS. Key secondary outcomes included safety and the achievement of minimal disease activity (MDA) criteria and PASDAS low disease activity (LDA) (≤3.2).ResultsA total of 78 PsA patients (MTX + LEF n=39; MTX + placebo n=39) were included. The mean age was 53.1 (SD=12.8) years and 36% (n=28) of the patients were female. The mean PASDAS at baseline was 4.9 (SD=1) in both treatment groups. Table 1 shows that MTX plus LEF was superior to MTX plus placebo at week 16 (PASDAS 3.1, SD=1.4 vs 3.7, SD=1.3; treatment difference= -0.6, 90% CI -1.0 to -0.1, one-sided P-value=0.025). Similar and significant results were found for achievement of MDA criteria (59% vs 33%, one-sided P-value=0.013) and PASDAS LDA (59% vs 35%, one-sided P-value=0.019) (Figure 1 and Table 1). Other favorable and significant outcomes for the MTX plus LEF group included -among others- the improvement in swollen joint count (SJC) (median [IQR] = -3 [-5, -2] vs -2 [-4, 0], one-sided P-value=0.039) and the proportion of patients with active psoriasis (i.e. body surface area score >0) at week 16 (44% vs 68%, one-sided P-value=0.014). Generally mild adverse events and treatment discontinuation (MTX+LEF n/N=10/39; MTX + placebo n/N=3/39) occurred more frequently in the MTX plus LEF group.Table 1.Primary and secondary outcomes at week 16MTX + LEF(N=39)MTX + placebo (N=38)*Absolute difference [90% CI]P-valueOne-sidedPrimary endpointPASDAS at week 163.1 (1.4)3.7 (1.3)-0.6 [-1.0, -0.1]0.025Selected secondary endpointsFulfilling PASDAS LDA, N (%)23 (59)13 (35)24% [6, 42]0.019Fulfilling MDA criteria, N (%)23 (59)12 (33)26% [7, 44]0.013SJC66, change from baseline, median (Q1, Q3)-3 (-5, -2)-2 (-4, 0)..0.039TJC68, change from baseline, median (Q1, Q3)-2 (-4, 0)-2 (-5, 0)..0.457VAS physician global, change from baseline, mean (SD)-22.0 (21.9)-12.2 (19.7)-9.8 [-17.7, -1.9]0.021VAS patient global, change from baseline, mean (SD)-20.9 (24.4)-13.9 (28.3)-7.0 [-17.0, 3.0]0.124Active psoriasis, N (%)17 (44)26 (68)-25% [-43, -7]0.014* One patient in the MTX + LEF group was excluded from the efficacy analysis due to change of diagnosis.Figure 1.Proportion of patients meeting different PsA responder criteria for low disease activity at week 16* = one-sided P-value <0.05DAPSA = Disease Activity in Psoriatic ArthritisConclusionMTX plus LEF combination therapy resulted in a significantly greater improvement in disease activity according to PASDAS and MDA than treatment with MTX monotherapy in patients with PsA after 16 weeks. In addition, a greater improvement in psoriasis was found for the combination group. However, there are indications that MTX plus LEF combination is less well tolerated than MTX monotherapy.AcknowledgementsWe would like to thank all the patients that participated in this study; all rheumatologists from the Sint Maartenskliniek that helped with the patient inclusion; our patient partners and especially R. van den Griend; Dr. E.

Abstract
Background:Initiation of urate lowering therapy (ULT) is associated with an increase in gout flares1. Therefore, guidelines advice prophylactic therapy during the first six months of ULT2. Colchicine 0.5-1 mg/day is recommended. Whether 1 mg/day colchicine is superior to 0.5 mg/day is unknown.Objectives:To examine the difference in gout flares in the first six months after initiation of ULT between 0.5 and 1.0 mg/day colchicine prophylaxis.Methods:Patients with clinical diagnosis of gout, a first outpatient visit between January 2010 and March 2018 and a follow-up of at least 6 months were included in a retrospective cohort study, conducted in two rheumatology centres in the Netherlands. Within this cohort, patients starting ULT and colchicine prophylaxis were selected. Difference in gout flare incidence density (ID) in the first six months after start of ULT between colchicine 0.5 and 1.0 mg/day was analysed using Poisson regression, corrected for confounders. Secondary analyses included the proportion of patients reaching a target of serum urate acid (SUA) of < 0.36 mmol/l within the first six months.Results:Of 2108 gout patients, 379 patients started ULT and used colchicine prophylaxis (table 1). ID of flares was 2.8 and 2.6 per patient year on colchicine 1.0 and 0.5 mg/day respectively, resulting in an incidence rate ratio of 1.05 (95% CI 0.86 – 1.27). Within the first six months 68% in the colchicine 1mg/day and 63% in the colchicine 0.5 mg/day reached their target (difference 5%, 95% CI -0.08 – 0.18).Table 1.Baseline patient, disease and treatment characteristicsColchicine prophylaxis0,5 mg/day (n=275)1 mg/day (n=104)Men, no.

For generalisability it should be noted that flare rates were not very high, probably due to the background ULT being characterised by a “start low, go slow” approach. In this context colchicine 0.5 mg/day is sufficient as prophylaxis.References:[1]Seth R et al. J Rheumatol 2014;92;42-47.[2]Richette P et al.
