Unraveling the potential clinical utility of circulating tumor DNA detection in colorectal cancer-evaluation in a nationwide Danish cohort.

BACKGROUND: Increasingly, circulating tumor DNA (ctDNA) is proposed as a tool for minimal residual disease (MRD) assessment. Digital PCR (dPCR) offers low analysis costs and turnaround times of less than a day, making it ripe for clinical implementation. Here, we used tumor-informed dPCR for ctDNA detection in a large colorectal cancer (CRC) cohort to evaluate the potential for post-operative risk assessment and serial monitoring, and how the metastatic site may impact ctDNA detection. Additionally, we assessed how altering the ctDNA-calling algorithm could customize performance for different clinical settings. PATIENTS AND METHODS: Stage II-III CRC patients (N = 851) treated with a curative intent were recruited. Based on whole-exome sequencing on matched tumor and germline DNA, a mutational target was selected for dPCR analysis. Plasma samples (8 ml) were collected within 60 days after operation and-for a patient subset (n = 246)-every 3-4 months for up to 36 months. Single-target dPCR was used for ctDNA detection. RESULTS: Both post-operative and serial ctDNA detection were prognostic of recurrence [hazard ratio (HR) = 11.3, 95% confidence interval (CI) 7.8-16.4, P < 0.001; HR = 30.7, 95% CI 20.2-46.7, P < 0.001], with a cumulative ctDNA detection rate of 87% at the end of sample collection in recurrence patients. The ctDNA growth rate was prognostic of survival (HR = 2.6, 95% CI 1.5-4.4, P = 0.001). In recurrence patients, post-operative ctDNA detection was challenging for lung metastases (4/21 detected) and peritoneal metastases (2/10 detected). By modifying the cut-off for calling a sample ctDNA positive, we were able to adjust the sensitivity and specificity of our test for different clinical contexts. CONCLUSIONS: The presented results from 851 stage II-III CRC patients demonstrate that our personalized dPCR approach effectively detects MRD after operation and shows promise for serial ctDNA detection for recurrence surveillance. The ability to adjust sensitivity and specificity shows exciting potential to customize the ctDNA caller for specific clinical settings.

Bicaudal D2 autoantibodies are highly specific for systemic sclerosis.

OBJECTIVE: Autoantibodies directed against the intracellular protein bicaudal D2 (BICD2) have been identified as a specific marker of systemic sclerosis (SSc). Since autoantibodies are of value in predicting disease onset and identifying meaningful clinical subsets, as well as having prognostic value, this study aimed to establish the prevalence of BICD2 autoantibodies (anti-BICD2) in a cohort of patients with connective tissue disease and healthy controls. METHOD: In this cross-sectional study, 363 patients with connective tissue disease (121 SSc, 141 systemic lupus erythematosus, 101 myositis, and 100 blood donors) were tested for the presence of anti-BICD2. All SSc patients were tested for specific anti-nuclear antibodies (ANAs), and clinical and laboratory associations were evaluated in the SSc patients, stratified by anti-BICD2 status. RESULTS: In the SSc cohort, 35 patients had autoantibodies directed against BICD2. The specificity of anti-BICD2 in SSc patients was 96.5%; however, the sensitivity was only 28.9%. Anti-BICD2 and centromere autoantibodies were present together in 91% of the anti-BICD2-positive SSc patients, and in none of the cases was anti-BICD2 the only antibody present. Anti-BICD2-positive patients had lower forced expiratory volume in 1 s (FEV1) (p = 0.01) and lower carbon monoxide transfer coefficient (KCO) (p = 0.01) than anti-BICD2-negative SSc patients, but they had higher forced vital capacity (p = 0.03). CONCLUSION: Autoantibodies against BICD2 were highly specific for SSc patients. Reduced FEV1 and KCO in anti-BICD2-positive patients may indicate that the presence of anti-BICD2 is associated with altered lung function in an unknown pathophysiological manner, which awaits further elucidation.

Culture media affect sex after IVF treatment-a detailed analysis of explanatory variables.

PURPOSE: The purpose of this study was to provide a detailed analysis of clinical and laboratory factors associated with skewed secondary sex ratio (SSR) after ART. METHOD: Retrospective cohort study of embryos resulting in live births, from frozen and fresh single blastocyst transfers. Embryos were cultured in either G-TL (n = 686) or Sage media (n = 685). Data was analyzed using a multivariate logistic regression model and a mixed model analysis. RESULTS: Significantly more male singletons were born after culture in Sage media compared to G-TL media (odds ratio (OR) 1.34, 95% CI (1.05, 1.70), P = 0.02). Inner cell mass grade B vs A (OR 1.36 95% CI (1.05, 1.76), P = 0.02) and one previous embryo transfer (OR 1.49, 95% CI (1.03, 2.16), P = 0.03) were associated with a significantly higher probability of male child at birth. Factors associated with a reduced probability of male child were expansion grade 3 vs 5 (OR 0.66, 95% CI (10.45, 0.96), P = 0.03) and trophectoderm grade B vs A (OR 0.57, 95% CI (0.44, 0.74), P = 0.00). Male embryos developed significantly faster in Sage media compared to G-TL media for the stages of blastocyst (- 1.12 h, 95% CI (- 2.12, - 0.12)), expanded blastocyst (- 1.35 h, 95% CI (- 2.34, - 0.35)), and hatched blastocyst (- 1.75 h, 95% CI (- 2.99, - 0.52)). CONCLUSION: More male children were born after culture in Sage media compared to G-TL media. Male embryo development was affected by culture media. Our observations suggest that culture media impact male embryo quality selectively, thus potentially favoring the selection of male embryos.

Randomized Phase 3 trial demonstrating high efficacy, favourable safety and convenience of a novel calcipotriol and betamethasone dipropionate cream for the treatment of psoriasis.

BACKGROUND: The fixed dose combination of calcipotriene (CAL) and betamethasone dipropionate (BDP) is a well-established topical treatment option for psoriasis based on strong scientific rationale for the single agents having complementary efficacy and safety. CAL/BDP PAD-cream is an easily spreadable cream based on PAD Technology™, an innovative formulation and drug delivery system. OBJECTIVES AND METHODS: A Phase 3, multicentre, randomized, investigator-blind, active and vehicle-controlled trial enrolling 490 patients with mild to moderate psoriasis according to the Physician Global Assessment (PGA) scale was conducted in three European countries. Products were applied once daily for 8 weeks. The aim of the trial was to evaluate the efficacy and safety of CAL/BDP PAD-cream as well as treatment acceptability compared to CAL/BDP gel and PAD-cream vehicle. Primary endpoint was percentage change in modified Psoriasis Area and Severity Index (mPASI) from baseline to Week 8. RESULTS: The percentage mean change from baseline to Week 8 in mPASI for CAL/BDP PAD-cream (67.5%) was superior compared to PAD-cream vehicle (11.7%; p < 0.0001) and non-inferior to CAL/BDP gel (63.5%). The proportion of patients achieving PGA treatment success (at least two-step improvement to clear or almost clear) after 8 weeks was superior for CAL/BDP PAD-cream (50.7%) compared to PAD-cream vehicle (6.1%, p < 0.0001) and statistically significantly greater than CAL/BDP gel (42.7%, p = 0.0442). Patient-reported psoriasis treatment convenience score (PTCS) for CAL/BDP PAD-cream was rated superior to CAL/BDP gel at Week 8 (p < 0.0001) and the mean change in DLQI from baseline to Week 8 improved statistically significantly more in the CAL/BDP PAD-cream group compared to both PAD-cream vehicle (p < 0.0001) and CAL/BDP gel (p = 0.0110). Safety assessments during the trial demonstrated that CAL/BDP PAD-cream was well-tolerated. CONCLUSION: CAL/BDP PAD-cream is a novel topical treatment of psoriasis that has a high efficacy and a favourable safety profile combined with a superior patient-reported treatment convenience.

HSP90 inhibitor RGRN-305 for oral treatment of plaque-type psoriasis: efficacy, safety and biomarker results in an open-label proof-of-concept study.

BACKGROUND: HSP90 is a downstream regulator of tumour necrosis factor (TNF)-α and interleukin (IL)-17A signalling and may therefore serve as a novel target in the treatment of psoriasis. OBJECTIVES: This phase Ib proof-of-concept study was undertaken to evaluate the safety and efficacy of a novel HSP90 inhibitor (RGRN-305) in the treatment of plaque psoriasis. METHODS: We conducted an open-label, single-arm, dose-selection, single-centre proof-of-concept study. Patients with plaque psoriasis were treated with 250 mg or 500 mg RGRN-305 daily for 12 weeks. Efficacy was evaluated clinically using the Psoriasis Area and Severity Index (PASI), body surface area (BSA), Physician's Global Assessment (PGA) scores and the Dermatology Life Quality Index (DLQI). Skin biopsies collected at baseline and at 4, 8 and 12 weeks after initiation of treatment were used for immunohistochemical staining and for gene expression analysis. Safety was monitored via laboratory tests, vital signs, electrocardiogram and physical examinations. RESULTS: Six of the 11 patients who completed the study responded to RGRN-305 with a PASI improvement between 71% and 94%, whereas five patients were considered nonresponders with a PASI response < 50%. No severe adverse events were reported. Four of seven patients treated with 500 mg RGRN-305 daily experienced a mild-to-moderate exanthematous drug-induced eruption owing to the study treatment. Two patients chose to discontinue the study because of this exanthematous eruption. RGRN-305 treatment resulted in pronounced inhibition of the IL-23, TNF-α and IL-17A signalling pathways and normalization of both histological changes and psoriatic lesion gene expression profiles in patients who responded to treatment. CONCLUSIONS: Treatment with RGRN-305 showed acceptable safety, especially in the low-dose group, and was associated with clinically meaningful improvement in a subset of patients with plaque psoriasis, indicating that HSP90 may serve as a novel future target in psoriasis treatment.

Long-term efficacy and safety of brodalumab in moderate-to-severe plaque psoriasis: a post hoc pooled analysis of AMAGINE-2 and -3.

BACKGROUND: Brodalumab is a monoclonal antibody that blocks multiple interleukin (IL)-17 family cytokines by binding to the shared A subunit of the IL-17 receptor. In Phase 3 trials, brodalumab provided high levels of skin clearance through 52 weeks in patients with moderate-to-severe psoriasis and was generally well tolerated. OBJECTIVES: To assess efficacy response rates and safety outcomes through 120 weeks for patients with moderate-to-severe psoriasis who received brodalumab. METHODS: Safety and efficacy data were pooled for patients from AMAGINE-2 and -3 who received continuous brodalumab 210 mg every 2 weeks, or brodalumab 210 mg every 2 weeks after receiving either brodalumab 140 mg or placebo through Week 12. Efficacy data are presented using observed data, non-responder imputation (NRI) and a combination of NRI and missing at random assumption to account for missing data. Absolute PASI scores are presented using mixed-effect model repeated measure modelling and multiple imputation. RESULTS: Based on observed data at Week 120, 86% of the continuous brodalumab 210 mg group achieved PASI 90 and 74% achieved PASI 100. At Week 12, 58% of this group achieved absolute PASI ≤1; this proportion increased to approximately 80% at Week 52 and persisted through Week 120. Among patients receiving continuous brodalumab 210 mg, median duration of brodalumab exposure was 747 days and the overall exposure-adjusted event rate of treatment emergent adverse events per 100 patient-years was 329. Safety through 120 weeks was comparable to the results of the primary AMAGINE-2 and -3 studies. Patients who switched to brodalumab 210 mg after receiving either brodalumab 140 mg or placebo through Week 12 showed similar skin clearance and safety profiles. CONCLUSIONS: Brodalumab treatment was well tolerated and resulted in high levels of skin clearance that were rapidly achieved and maintained through Week 120, supporting its long-term efficacy and safety profile.

Prevalence and characterization of treatment-refractory psoriasis and super-responders to biologic treatment: a nationwide study.

INTRODUCTION: Treatment with biologics often leads to clearance of psoriasis. However, some patients do repeatedly fail to respond and/or lose an achieved response (treatment refractory) to the biologic, whereas other patients achieve excellent response to one biologic and remain clear of psoriasis for several years (super-responders). OBJECTIVE: To identify and characterize patients with treatment refractory psoriasis and patients who are super-responders to biologic treatment. MATERIAL AND METHODS: Patients registered in DERMBIO between January 2007 and November 2019 were included. Patients were categorized as being treatment refractory if they had had treatment failure to ≥3 biologics targeting ≥2 different pathways. Super-responders were patients treated with their first biologic for minimum 5 years without an absolute psoriasis area and severity index (PASI) > 3 between 6 months and 5 years of treatment. All remaining patients from DERMBIO served as comparators. RESULTS: In total, 3280 patients were included with a mean age of 45.0 years. 1221 (37%) of the patients were females. Of the included patients, 214 (6.5%) were categorized as treatment refractory and 207 (6.3%) were categorized as super-responders. Treatment refractory patients had higher mean body weight (100.6 kg vs. 90.6 kg, P < 0.0001) and higher mean BMI (32.2 vs. 29.4, P < 0.0001) compared with the rest of patients in DERMBIO. Super-responders had higher socioeconomic status and fewer comorbidities compared with the comparator group (P < 0.0001). CONCLUSION: A small proportion of patients with psoriasis treated with biologics are either super-responders or treatment refractory. Treatment refractory patients have higher body weight, whereas super-responders have fewer comorbidities and higher socioeconomic status.

Prevalence and severity of coronary artery disease linked to prognosis in psoriasis and psoriatic arthritis patients: a multi-centre cohort study.

OBJECTIVES: (i) To estimate the prevalence and severity of coronary artery disease and (ii) to assess the risk of cardiovascular events and mortality, in patients with psoriasis and psoriatic arthritis (PsA) in a large-scale cohort of patients referred to coronary computed tomography angiography (CTA). METHODS: This was a cross-sectional study with follow-up of 46,022 patients based on data from a Danish national CTA registry. Exposure was defined as psoriasis or PsA. A group of patients without psoriasis, PsA or any other inflammatory disease was used as reference. Cross-sectional primary outcomes were a coronary artery calcium score (CACS) >0 and CACS ≥400, and secondary outcome was obstructive CAD. At follow-up, the primary outcome was a composite endpoint of cardiovascular events and all-cause mortality. All outcomes were adjusted for traditional cardiovascular risk factors. RESULTS: We identified 1356 psoriasis and 370 PsA patients. The adjusted odds ratio (OR) for psoriasis patients for CACS >0, CACS ≥400 and obstructive CAD was 1.26 (1.10-1.46), 1.25 (1.04-1.50) and 1.14 (0.98-1.33), respectively. For PsA patients, OR for CACS >0 was 1.28 (1.00-1.64). We found a crude hazard ratio (HR) of 1.49 (1.21-1.85) and adjusted HR of 1.14 (0.92-1.41) for the primary outcome in psoriasis patients. CONCLUSIONS: In this population, both psoriasis and PsA were associated with an increased prevalence of coronary calcification. Psoriasis patients also showed an increased prevalence of severe calcification. Psoriasis patients were at increased risk for cardiovascular events and death, however not after adjusting for the effect of other predictors.

Early efficacy and safety data with fixed-dose combination calcipotriol/betamethasone dipropionate foam attributed to mechanism of absorption and steroid potency.

Topical therapy is the mainstay of treatment for the majority of patients with psoriasis vulgaris (chronic plaque psoriasis), with combinations of vitamin D analogues and glucocorticoids having been shown to negate many of the negative effects associated with either monocomponent individually. Following the established efficacy of fixed-dose combination calcipotriol (Cal; 50 µg/g) plus betamethasone dipropionate (BD; 0.5 mg/g) ointment and gel formulations, a novel Cal/BD foam formulation was developed. When applied, Cal/BD foam forms a supersaturated solution on the skin, increasing the penetration and bioavailability of Cal and BD. Early data indicate that this results in improved efficacy outcomes versus Cal/BD ointment, without negatively affecting safety outcomes (such as the incidence/severity of side effects or impacted calcium homeostasis or hypothalamic-pituitary-adrenal axis). This article discusses the potency and absorption of fixed-dose combination Cal/BD foam, as well as the positive early efficacy and safety data associated with its utilisation in the treatment of psoriasis vulgaris.

Efficacy and safety of mogamulizumab by patient baseline blood tumour burden: a post hoc analysis of the MAVORIC trial.

BACKGROUND: Mogamulizumab was compared with vorinostat in the phase 3 MAVORIC trial (NCT01728805) in 372 patients with relapsed/refractory mycosis fungoides (MF) or Sézary syndrome (SS) who had failed ≥1 prior systemic therapy. Mogamulizumab significantly prolonged progression-free survival (PFS), with a superior objective response rate (ORR) vs. vorinostat. OBJECTIVES: This post hoc analysis was performed to evaluate the effect of baseline blood tumour burden on patient response to mogamulizumab. METHODS: PFS, ORR, time to next treatment (TTNT), skin response (modified Severity-Weighted Assessment Tool [mSWAT]) and safety were assessed in patients stratified by blood classification (B0 [n = 126], B1 [n = 62], or B2 [n = 184], indicating increasing blood involvement). RESULTS: Investigator-assessed PFS was longer for mogamulizumab versus vorinostat across all blood classes, significantly so for B1 and B2 patients. ORR was higher with mogamulizumab than with vorinostat in all blood classification groups and more markedly so with escalating B class (B0: 15.6% vs. 6.5%, P = 0.0549; B1: 25.8% vs. 6.5%, P = 0.2758; B2: 37.4% vs. 3.2%, P < 0.0001). TTNT was significantly longer for patients treated with mogamulizumab versus vorinostat with B1 (12.63 vs. 3.07 months; HR 0.32 [95% CI 0.16-0.67]; P = 0.0018) and B2 (13.07 vs. 3.53 months; HR 0.30 [95% CI 0.21-0.43]; P < 0.0001) blood involvement. In the mogamulizumab arm, 81 patients (43.5%) had ≥50% change in the mSWAT vs. 41 patients (22.0%) with vorinostat; mSWAT improvements with mogamulizumab occurred most often in B1 and B2 patients. Rapid, sustained reductions were seen in CD4+ CD26- cell counts and CD4:CD8 ratios in mogamulizumab patients for all B classes. Treatment-emergent adverse events were less frequent overall with mogamulizumab and similar in frequency regardless of B class. CONCLUSIONS: This post hoc analysis indicates greater clinical benefit with mogamulizumab vs. vorinostat in patients with MF and SS classified as having B1 and B2 blood involvement.

Long-term efficacy and safety of tildrakizumab for moderate-to-severe psoriasis: pooled analyses of two randomized phase III clinical trials (reSURFACE 1 and reSURFACE 2) through 148 weeks.

BACKGROUND: Tildrakizumab is a specific anti-interleukin-23p19 monoclonal antibody approved for the treatment of plaque psoriasis. OBJECTIVES: To evaluate the long-term efficacy and safety of tildrakizumab treatment for patients with moderate-to-severe psoriasis for up to 148 weeks. METHODS: Pooled analysis from two double-blind, randomized controlled trials: reSURFACE 1 and reSURFACE 2. Efficacy was assessed for responders (≥ 75% improvement in Psoriasis Area and Severity Index; PASI 75) and partial responders (PASI 50-75) to tildrakizumab 100 mg and 200 mg at week 28 who were maintained on the same dose (administered every 12 weeks), and for partial responders or nonresponders (PASI < 50) to etanercept 50 mg at week 28 who, after a 4-week washout, were switched to tildrakizumab 200 mg (administered at weeks 32 and 36, and every 12 weeks thereafter). Safety was assessed in the all-patients-as-treated population. Three different methods of imputing missing data were used: nonresponder imputation (NRI), multiple imputation and observed cases. The Clinicaltrials.gov numbers are NCT01722331 (reSURFACE 1) and NCT01729754 (reSURFACE 2). RESULTS: At week 148 (NRI), 72·6%, 53·8% and 28·9% of tildrakizumab 100-mg responders and 80·2%, 59·9% and 32·6% of tildrakizumab 200-mg responders had PASI 75, 90 and 100 responses, respectively. For partial responders to tildrakizumab 100 mg and 200 mg, the proportions of patients achieving PASI 75, 90 and 100 responses were 32·5%, 25·0% and 10·0%; and 47·1%, 27·5% and 12·8%, respectively. For patients who were partial responders or nonresponders to etanercept, the proportions of patients achieving PASI 75, 90 and 100 responses were 66·9%, 43·8% and 14·9% at week 148. Rates of discontinuations due to adverse events [tildrakizumab 100 mg: 1·7 per 100 patient-years (PYs); tildrakizumab 200 mg: 1·2 per 100 PYs] and exposure-adjusted rates of serious adverse events (5·9 per 100 PYs; 5·5 per 100 PYs), severe infections (1·1 per 100 PYs; 1·1 per 100 PYs), malignancies (0·6 per 100 PYs; 0·4 per 100 PYs) and major adverse cardiovascular events (0·4 per 100 PYs; 0·5 per 100 PYs) were low. CONCLUSIONS: Tildrakizumab was well tolerated and efficacy was well maintained in week 28 responders who continued tildrakizumab treatment through 3 years, or improved among etanercept partial responders or nonresponders who switched to tildrakizumab. What's already known about this topic? Tildrakizumab 100 mg and 200 mg are efficacious and well tolerated with short-term use in the treatment of patients with moderate-to-severe plaque psoriasis. What does this study add? High levels of efficacy are maintained for up to 3 years of psoriasis treatment with tildrakizumab. There is a favourable long-term safety profile with both tildrakizumab 100 mg and 200 mg, with a low incidence of adverse events of special interest through 3 years.

Validation of the Danish Colorectal Cancer Group (DCCG.dk) database - on behalf of the Danish Colorectal Cancer Group.

AIM: The aim of this study was to validate the clinical quality database of the Danish Colorectal Cancer Group. The validation is meant to focus on core data regarding staging of the disease, treatment provided, patient-related factors and key complications. METHOD: This was a database validation study assessing the completeness of the database and the accuracy of the data by re-entering core variables into an online module in a blinded fashion and comparing re-entered data with the original database data. A sample of 5% of patients from the years 2014-2017 was randomly selected. RESULTS: The sample of 936 patients was identified and data were re-entered. The completeness of the data retrieved was a median of 96%, 100% and 99% for preoperative, intra-operative and postoperative variables, respectively. The overall accuracy was a median of 95%. The least accurate variable was date of diagnosis (50% perfect agreement), with agreement rising to 96% when near matches defined as correct date ± 30 days were included. Intra-operative variables were of high quality, as were data on surgical complications including anastomotic leakage, where agreement was 97%. CONCLUSION: This was the first major validation of the Danish Colorectal Cancer Group's database. Overall, the completeness and quality of data were high, but the validation process also identified weaknesses, which can be crucial for future users to acknowledge and consider.

Localization of treatment-resistant areas in patients with psoriasis on biologics.

BACKGROUND: Traditionally, psoriasis in certain body sites such as the scalp, nails, palms, soles and intertriginous areas has been acknowledged as difficult to treat. OBJECTIVES: To investigate the body location of treatment-resistant psoriasis in patients treated with biologic agents in real-world clinical practice, and to study the association between localization and quality of life. METHODS: This was an observational, noninterventional, study. We investigated the skin and/or nail location of treatment-resistant psoriasis in patients with moderate-to-severe psoriasis treated for > 6 months with biologic agents. A partial or good response to treatment was defined as having a Psoriasis Area and Severity Index (PASI) score ≥ 1 and ≤ 5. Experienced PASI assessors used a uniform data collection form in which the body area was divided into 26 regions and 20 nails. RESULTS: We included 146 patients with chronic plaque-type psoriasis (109 men, 74·7%, mean ± SD age 49·8 ± 13·7 years), with a median PASI score of 2·4 (interquartile range 1·2-3·2). The median PASI reduction from treatment initiation was 86·1% (interquartile range 78·1-91·3). The most common site of recalcitrant psoriasis was the anterior lower leg [49·3%; 95% confidence interval (CI) 41·2-57·4]. Further common sites of recalcitrant psoriasis were the posterior lower leg (24·7%; 95% CI 17·7-31·6), elbow (35·6%; 95% CI 27·8-43·4) and the scalp (19·2%; 95% CI 12·8-25·6%). No association between Dermatology Life Quality Index and specific areas of recalcitrant psoriasis were observed. CONCLUSIONS: In real-world clinical practice, the most common sites of recalcitrant psoriasis in patients treated with biologic agents are the anterior lower leg, posterior lower leg and elbows. Recalcitrant psoriasis in no specific area caused a greater impact on quality of life than any other area.

Preadmission use of antidepressants and risk of complications and death after colorectal cancer surgery: a nationwide population-based cohort study.

AIM: Few studies have evaluated how preadmission use of antidepressants affects outcomes in colorectal cancer (CRC) patients after they have undergone surgery. Therefore, our aim is to examine whether preadmission use of antidepressants increased the risk of complications and death in patients who underwent CRC surgery. METHOD: Using the Danish Colorectal Cancer Group Database we identified patients who underwent CRC surgery in Denmark from 2005 to 2012. We identified prescriptions for antidepressants redeemed within 1 year prior to surgery and categorized patients as current users (≤ 90 days), former users (91-365 days) and nonusers. All patients were followed from surgery to 30 days thereafter or to death. We calculated 30-day rates of complications, intensive care unit (ICU) admission and mortality and compared these between users and nonusers using logistic and Cox regression adjusting for potential confounders. RESULTS: Of 27 374 patients, 8.9% were current users and 3.0% were former users. Antidepressant users were older and had more comorbidity but a similar cancer stage. Compared with nonusers, current users had a higher risk of postoperative reoperation [adjusted odds ratio (aORs) = 1.15 (95% CI 1.02-1.30)], medical complications [aORs = 1.41 (95% CI 1.25-1.60)] and increased ICU admission rate [adjusted hazard ratio (aHR) = 1.32 (95% CI 1.21-1.45)]. The 30-day mortality was 11.4% for current users, 9.1% for former users and 6.2% for nonusers [aHR = 1.34 (95% CI 1.17-1.53) for current vs nonusers]. CONCLUSION: Patients with preadmission use of antidepressants had a higher risk of complications and ICU admission, and higher 30-day mortality following CRC surgery than nonusers.

Treatment use and satisfaction among patients with psoriasis and psoriatic arthritis: results from the NORdic PAtient survey of Psoriasis and Psoriatic arthritis (NORPAPP).

BACKGROUND: There are scarce data in Scandinavia about treatment satisfaction among patients with psoriasis (PsO) and/or psoriatic arthritis (PsA). The number of patients receiving systemic treatment is unknown. OBJECTIVE: To describe patients' experience of treatments for PsO/PsA in Sweden, Denmark and Norway, addressing communication with physicians, satisfaction with treatment and concerns regarding treatment options. METHODS: The NORdic PAtient survey of Psoriasis and Psoriatic arthritis (NORPAPP) asked 22 050 adults (randomly selected from the YouGov panels in Sweden, Denmark and Norway) whether they had PsO/PsA. A total of 1264 individuals who reported physician-diagnosed PsO/PsA were invited to participate in the full survey; 96.6% responded positively. RESULTS: Systemic treatment use was reported by 14.6% (biologic: 8.1%) of respondents with PsO only and by 58.5% (biologic: 31.8%) of respondents with PsA. Biologic treatments were more frequently reported by respondents considering their disease severe (26.8% vs 6.7% non-severe) and those who were members of patient organizations (40.7% vs 6.9% non-members). Discussing systemic treatments with their physician was reported significantly more frequently by respondents with PsA, those perceiving their disease as severe (although 35.2% had never discussed systemic treatment with their physician) and those reporting being a member of a patient organization (P < 0.05). Many respondents reported health risk concerns and dissatisfaction with their treatment. Of special interest was that respondents aged 45-75 years reported less experience with biologics (8.1%) than those aged 18-44 years (21.5%). The older respondents also reported more uncertainty regarding long-term health risks related to systemic treatments (most [66.7-72.9%] responded 'do not know' when asked about the risk of systemic options). CONCLUSION: It appears likely that substantial numbers of Scandinavians suffering from severe PsO/PsA are not receiving optimal treatment from a patient perspective, particularly older patients. Also, one-third of respondents with severe symptoms had never discussed systemic treatment with a physician.

Associations between functional polymorphisms and response to biological treatment in Danish patients with psoriasis.

Biological agents including anti-tumor necrosis factor (anti-TNF; adalimumab, infliximab, etanercept) and anti-interleukin-12/13 (IL12/23; ustekinumab) are essential for treatment of patients with severe psoriasis. However, a significant proportion of the patients do not respond to a specific treatment. Pharmacogenetics might be a way to predict treatment response. Using a candidate gene approach, 62 mainly functional single-nucleotide polymorphisms (SNPs) in 44 different genes were evaluated in 478 Danish patients with psoriasis undergoing 376 series of anti-TNF treatment and 230 series of ustekinumab treatment. Associations between genetic variants and treatment outcomes (drug survival and Psoriasis Area Severity Index reduction) were assessed using logistic regression analyses (crude and adjusted for gender, age, psoriatic arthritis and previous treatment). After correction for multiple testing controlling the false discovery rate, six SNPs (IL1B (rs1143623, rs1143627), LY96 (rs11465996), TLR2 (rs11938228, rs4696480) and TLR9 (rs352139)) were associated with response to anti-TNF treatment and 4 SNPs (IL1B (rs1143623, rs1143627), TIRAP (rs8177374) and TLR5 (rs5744174)) were associated with response to ustekinumab treatment (q<0.20). The results suggest that genetic variants related to increased IL-1ß levels may be unfavorable when treating psoriasis with either anti-TNF or ustekinumab, whereas genetic variants related to high interferon-γ levels may be favorable when treating psoriasis with ustekinumab.

Pelvic insufficiency fractures frequently occur following preoperative chemo-radiotherapy for rectal cancer - a nationwide MRI study.

AIM: The aim of this prospective case-control study was to evaluate the rate of pelvic insufficiency fractures (PIFs) in Denmark using MRI at the 3-year follow-up. All patients had rectal cancer and had undergone surgery with or without preoperative chemo-radiotherapy (CRT). METHOD: Patients registered with primary rectal cancer in the Danish Colorectal Cancer Group database, who underwent rectal cancer resection from April 2011 through August 2012, were invited to participate in a national MRI study aiming to detect local recurrence and evaluate quality of the surgical treatment. Pelvic MRI including bone-specific sequences 3 years after treatment was obtained. The primary outcome was the rate of PIFs; secondary outcome was risk factors of PIFs evaluated in multivariate analysis. RESULTS: During the study period, 890 patients underwent rectal cancer surgery. Of these, 403 patients were included in the MRI study and had a 3-year follow-up MRI. PIFs were detected in 49 (12.2%; 95% CI 9.0-15.4) patients by MRI. PIFs were detected in 39 patients (33.6%; 95% CI 24.9-42.3) treated with preoperative CRT compared to 10 (3.5%; 95% CI 1.3-5.6) non-irradiated patients (P < 0.001). In a multivariate analysis female gender (OR = 3.52; 95% CI 1.7-7.5), age above 65 years (OR = 3.20; 95% CI 1.5-6.9) and preoperative CRT (OR = 14.20; 95% CI 6.1-33.1) were significant risk factors for PIFs. CONCLUSION: Preoperative CRT in the treatment of rectal cancer was associated with a 14-fold higher risk of PIFs after 3 years, whereas female gender and age above 65 years each tripled the risk of PIFs.

Psoriasis and risk of myocardial infarction before and during an era with biological therapy: a population-based follow-up study.

BACKGROUND: Attention towards cardiovascular disease prevention in patients with moderate to severe psoriasis increased with the introduction of biological therapy. OBJECTIVE: To determine the risk of myocardial infarction (MI) following hospital-diagnosed psoriasis compared with the general population, in eras before and following the introduction of biological therapy. METHODS: We conducted a cohort study in Denmark utilising nationwide prospectively collected data from population-based registries. For the early era cohort, we identified subjects with first time hospital-diagnosed psoriasis between 1995 and 2002, and, for the late era cohort, those diagnosed between 2006 and 2013. Comparison cohorts from the general population were matched (10:1) on sex and birth year. All individuals were followed from date of psoriasis diagnosis (index date for matched controls) until incidence of MI, death, emigration or end of study (1 January 2002 for the early era cohort; 1 January 2013 for the late era cohort). We computed the cumulative MI incidence at 5 years of follow-up, and used Cox regression to compute HRs of MI comparing psoriasis subjects with general population subjects. RESULTS: For the early era, we identified 4302 psoriatic subjects and 43 791 general population subjects; and for the late era, 4577 psoriatic subjects (4% received biologic therapy) and 46 376 general population subjects. The cumulative incidence of MI among psoriatic subjects in the early era was 2.5% and it was 2.2% in the late era. The HRs comparing MI risk in the psoriasis and general population cohorts were 1.40 (95% CI: 1.09-1.80), for the early era, and 1.39 (95% CI: 1.10-1.75) for the late era, adjusting for educational level and use of cardiovascular drugs. CONCLUSION: The increased risk of MI among patients with hospital-diagnosed psoriasis, relative to the general population, remained unchanged during the initial years of increased attention towards cardiovascular disease prevention and availability of biologic therapy.

Clinical use of dimethyl fumarate in moderate-to-severe plaque-type psoriasis: a European expert consensus.

Fumaric acid esters (FAEs) are a group of small molecules that were first investigated for the treatment of psoriasis in 1959. The first fumarate-based drug - Fumaderm® - was approved in Germany in 1994 for severe psoriasis and then in 2008, the label was expanded to include moderate psoriasis. Fumaderm is a combination of different FAEs: dimethyl fumarate (DMF), which is regarded as the main active component, plus calcium, magnesium and zinc salts of monoethyl fumarate (MEF). FAEs are the most frequently used first-line systemic psoriasis treatment in Germany, with an overall treatment experience comprising more than 220 000 patient-years. FAEs have demonstrated good, sustained clinical efficacy with an acceptable safety profile for the long-term treatment of patients with moderate-to-severe psoriasis. Indeed, the European S3-Guideline on the systemic treatment of Psoriasis vulgaris recommends FAEs for induction and long-term treatment. Until recently, FAEs were only licensed (for the psoriasis indication) in Germany, but were imported to many other European countries, such as The Netherlands, UK, Ireland, Austria and Italy, for the treatment of psoriasis. In 2017, the European Medicines Agency (EMA) approved Skilarence® , a new oral formulation of DMF, for the treatment of adult patients with moderate-to-severe chronic plaque psoriasis in need of systemic therapy. Skilarence only contains DMF and is the first FAE for the treatment of psoriasis that has been approved by the EMA. This approval has given rise to a new oral treatment option for patients with moderate-to-severe plaque psoriasis across Europe. Here, we report the results of an expert meeting which was convened to deliver clinician-agreed consensus and real-world guidance on the clinical use of DMF in moderate-to-severe chronic plaque psoriasis. Guidance on appropriate patient selection, DMF dosage considerations, monitoring and side-effect management is offered based upon available evidence and collective real-world clinical experience.

Secukinumab treatment in new-onset psoriasis: aiming to understand the potential for disease modification - rationale and design of the randomized, multicenter STEPIn study.

BACKGROUND: To date, biological treatments have been assessed in subjects with a long-term history of psoriasis and previous failures to systemic and topical therapies. In rheumatoid arthritis and other immune-mediated inflammatory diseases, early intensive systemic treatment prolongs treatment-free remission. We hypothesize that, by treating patients with psoriasis early with an effective systemic therapy, we may be able to alter the clinical outcome and the natural course of the disease. The STEPIn study (NCT03020199) investigates early intervention with secukinumab versus narrow-band ultraviolet B (nb-UVB) phototherapy in subjects with new-onset psoriasis. OBJECTIVE: To determine whether early intervention with either nb-UVB treatment or secukinumab in subjects with new-onset plaque psoriasis might modify the natural course of the disease. METHODS: One hundred and sixty subjects aged 18-50 years with new-onset (≤12 months) moderate-to-severe plaque psoriasis and naïve to systemic treatment and phototherapy will be randomized to secukinumab 300 mg or nb-UVB. The Main Study has two treatment arms: Arm A1, subcutaneous secukinumab 300 mg at baseline, Weeks 1, 2, 3 and 4, and every 4 weeks thereafter until and including Week 52; Arm B1, one/two cycles of nb-UVB for 12 weeks each (maximum 28-week break between cycles). After treatment discontinuation, patients will be followed up and monitored for disease activity up to Week 208. A Mechanistic Sub-study will assess immunological changes and pathogenic tissue-resident memory T cells in skin biopsies. CONCLUSIONS: STEPIn is the first study to investigate whether early intensive treatment in new-onset psoriasis can modify the long-term natural course of the disease and thus become a novel treatment strategy for patients with psoriasis.
