Performance of composite measures used in a trial of etanercept and methotrexate as monotherapy or in combination in psoriatic arthritis

Objectives: To examine which composite measures are most sensitive to change when measuring psoriatic arthritis (PsA) disease activity, analyses compared the responsiveness of composite measures used in a 48-week randomized, controlled trial of MTX and etanercept in patients with PsA. Methods: The trial randomised 851 patients to receive weekly: MTX (20 mg/week), etanercept (50 mg/week) or MTX plus etanercept. Dichotomous composite measures examined included ACR 20/50/70 responses, minimal disease activity (MDA) and very low disease activity (VLDA). Continuous composite measures examined included Disease Activity Score (28 joints) using CRP (DAS28-CRP), Clinical Disease Activity Index (CDAI), Simplified Disease Activity Index (SDAI), Disease Activity for Psoriatic Arthritis (DAPSA) and Psoriatic Arthritis Disease Activity Score (PASDAS). Results: At week 24, etanercept-treated groups were significantly more effective than MTX monotherapy to achieve ACR 20 (primary end point) and MDA (key secondary end point). When examining score changes from baseline at week 24 across the five continuous composite measures, PASDAS demonstrated relatively greater changes in the etanercept-treated groups compared with MTX monotherapy and had the largest effect size and standardized response. Joint count changes drove overall score changes at week 24 from baseline in all the continuous composite measures except for PASDAS, which was driven by the Physician and Patient Global Assessments. Conclusion: PASDAS was the most sensitive continuous composite measure examined with results that mirrored the protocol-defined primary and key secondary outcomes. Composite measures with multiple domains, such as PASDAS, may better quantify change in PsA disease burden. Trail registration: https://ClinicalTrials.gov, number NCT02376790

Morbidity Associated with Colostomy Reversal After Cytoreductive Surgery and HIPEC

ABSTRACT Background. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has improved the survival in selected colorectal cancer patients with peritoneal metastases. In these patients, the risk of a low anastomosis is sometimes diminished through the creation of a colostomy. Currently, the morbidity and mortality associated with the reversal of the colostomy in this population is unknown. Methods. Our study involved two prospectively collected databases including all patients who underwent CRS-HI-PEC. We identified all consecutive patients who had a colostomy and requested a reversal. The associations between four clinical and ten treatment-related factors with the outcome of the reversal procedure were determined by univariate analysis. Results. 21 of 336 patients (6.3 %) with a stoma with a mean age of 50.8 (standard deviation 10.2) years underwent a reversal procedure. One patient was classified as American Society of Anesthesiologists (ASA) grade III, 6 as ASA grade II, and the remaining as ASA grade I. Median time elapsed between HIPEC and reversal was 394 days (range 133-1194 days). No life-threatening complications or mortality were observed after reversal. The reversal-related morbidity was 67 %. Infectious complications were observed in 7 patients (33 %). Infectious complications after HIPEC were negatively correlated with the ultimate restoration of bowel continuity (P = 0.05). Bowel continuity was successfully restored in 71 % of the patients. Conclusions. Although the restoration of bowel continuity after CRS-HIPEC was successful in most patients, a relatively high complication rate was observed. Patients with infectious complications after HIPEC have a diminished chance of successful restoration of bowel continuity. Colorectal carcinoma is the third most common cancer worldwide, accounting for approximately 1 million newly diagnosed patients per year and over 600,000 deaths due to this disease. 1 Approximately 10-25 % of colorectal cancer patients develop peritoneal metastases, of whom 25 % present with the peritoneum as the sole site of distant metastases. 2-4 The peritoneum is a thin membrane that covers the abdominal wall and internal organs. 5 Peritoneal metastases are believed to be the result of tumor cell shedding into the peritoneal cavity, either spontaneously or as a result of spill during surgical procedures, ultimately resulting in the development of tumor deposits on the peritoneal surface

New treatment paradigms in spondyloarthritis

The review presents the recent rapid expansion of therapeutical options in spondyloarthritis. Additionally, it focuses on the importance of additional questions raised by the growing therapeutic possibilities related to the optimal use of these drugs. The emergence of new treatment options opens new avenues and opportunities for treating patients with nonresponse, contraindications, or intolerance for classic drugs. However, it becomes more relevant than ever to define not only drugs and treatment options but also treatment strategies. We address current literature and remaining questions on strategies such as early intervention, combination treatment, personalized medicine, and treat-to-target. Not only the treatment as such, but also the treatment strategy is crucial to reveal the full therapeutic potential and benefit for patients. Whereas cautious but crucial steps have been taken in the last years to explore these aspects, related to timing and sequence of treatment (including combination treatments), stratified medicine approaches, and treat-to-target strategies, it is now time for full-scale investment in prospective strategy trial

Ideal target for psoriatic arthritis? Comparison of remission and low disease activity states in a real-life cohort

Background Psoriatic arthritis (PsA) recommendations state that the target of treatment should be remission or low disease activity (LDA). We used a real-life dataset to compare different potential targets. Methods 250 patients with PsA considered in an acceptable disease state according to their rheumatologist were included. Targets for remission were the Disease Activity Index for Psoriatic Arthritis (DAPSA) and clinical DAPSA (cDAPSA) remission (4), very low disease activity (VLDA) and Psoriatic Arthritis Disease Activity Score 1.9. LDA targets analysed were the DAPSA 14, cDAPSA 13, minimal disease activity (MDA) and adjusted MDA targets: MDAjoints with both tender joint count (TJC) and swollen joint count (SJC) mandated, MDAskin (psoriasis area and severity index (PASI) mandated) and MDAjoints&skin with TJC, SJC and PASI mandated. Results Comparison of the several candidate targets demonstrates that VLDA is achieved by the lowest proportion of patients and includes patients with the lowest residual disease activity compared with the other remission targets. The modified MDA measures are the most stringent targets for LDA in terms of residual disease on joints, psoriasis and enthesitis within patients achieving the target. In both remission and LDA, the inclusion of C reactive protein did not show an added value. The exclusion of a skin domain, as in the DAPSA measures, resulted in negligence of skin disease and a negative impact on the quality of life in some patients. Conclusions The different remission and LDA targets show us significant overlap between measures, but these measures targeting the same definition do differ in terms of allowance of residual disease. Inclusion of laboratory markers seems unnecessary, although exclusion of a skin domain may result in psoriasis not being assessed resulting in residual impactful skin diseas

Response to: 'To DAPSA or not to DAPSA? That is not the question' by Schoels et al

We thank the authors for the interest in our paper and are grateful for the opportunity to respond to the points raised1. We agree that there is a clear distinction between composite measures of psoriatic arthritis such as DAPSA and composite measures of psoriatic disease such as MDA/VLDA and PASDAS. As the Vienna group rightly point out, these measures differ in terms of the components included, but not due to disagreement within the outcome measure community as suggested in the letter. The choice of components for each composite measure was decided using different methodology in the development of each one, thus resulting in different measures. We believe that this variation in scores is one reason for the need to compare such scores in different populations to establish the optimal measure or measures for PsA. Indeed when the DAPSA was originally suggested, it was because the same components used in the DAREA were identified in a principal component analysis (PCA) in PsA. Interestingly in this analysis, the variables tested were taken from the OMERACT PsA domains and therefore DAPSA was not, a priori, designed specifically to be a unidimensional composite measure. The fourth component identified in the PCA was the PASI highlighting the importance of skin in PsA despite the fact that patients had a low baseline mean PASI of only 3.3. Whilst PASI was not included in the DAPSA as the eigenvalue was 0.949 and therefore just under the threshold of 12, it is interesting to imagine how the results may have differed if it were developed in a group with slightly more active skin disease

Anti-IL-17A treatment reduces serum inflammatory, angiogenic and tissue remodeling biomarkers accompanied by less synovial high endothelial venules in peripheral spondyloarthritis

Spondyloarthritis (SpA) is characterized by inflammation and new bone formation. The exact pathophysiology underlying these processes remains elusive. We propose that the extensive neoangiogenesis in SpA could play a role both in sustaining/enhancing inflammation and in new bone formation. While ample data is available on effects of anti-TNF on angiogenesis, effects of IL-17A blockade on serum markers are largely unknown. We aimed to assess the impact of secukinumab (anti-IL-17A) on synovial neoangiogenesis in peripheral SpA, and how this related to changes in inflammatory and tissue remodeling biomarkers. Serum samples from 20 active peripheral SpA patients included in a 12 week open-label trial with secukinumab were analyzed for several markers of angiogenesis and tissue remodeling. Synovial biopsies taken before and after treatment were stained for vascular markers. Serum levels of MMP-3, osteopontin, IL-6 (all P < 0.001), IL-31, S100A8, S100A9, Vascular Endothelial Growth Factor A (VEGF-A), IL-33, TNF-α (all P < 0.05) decreased significantly upon anti-IL17A treatment. Secukinumab treatment resulted in a decrease in the number of synovial high endothelial venules and lymphoid aggregate score. These results indicate that anti-IL-17A not only diminishes inflammation, but also impacts angiogenesis and tissue remodeling/new bone formation. This may have important implications for disease progression and/or structural damage
