Background/objectives: Tightly-controlled dose reduction was possible during 1 year in psoriasis patients on adalimumab, etanercept or ustekinumab with low disease activity (CONDOR trial). Extended observation is needed to ensure long-term effectiveness and safety of the strategy. With prolonged follow-up, we investigated the clinical effects and safety of the strategy, the proportion of patients with successful dose reduction, and assessed if patients with a disease flare regained remission., Methods: Two-year follow up of a subgroup of patients previously included in a randomized pragmatic study comparing usual care (UC) with stepwise dose reduction (DR). Effectiveness (Psoriasis Area and Severity Index, PASI), Dermatology Life Quality Index (DLQI), adverse events, proportion of patients with successful DR and proportion of persistent disease flares were analyzed., Results: DR leads temporarily to a slightly increased PASI groupwise, but on the long-term patients regained low PASI. DLQI scores remained stable during follow-up. No serious adverse events due to DR were reported. Forty-one percent of patients remained on a low dose up to 2 years. The number of persistent flares was low in DR and UC., Conclusions: The proposed dose reduction strategy is effective for a significant part of patients and remains safe up to 2 years of follow-up.

Background: Although solely topical treatment often suffices, patients with psoriasis may require more intensive treatment (phototherapy and/or systemic treatments) to control their disease. However, in paediatric, adolescent and young adult patients, little is known about persistence of topical treatment and time until switch to systemic treatment., Objectives: To determine the median time from psoriasis onset until (i) discontinuation of solely topical agents and (ii) switch to systemic treatment, and to identify patient characteristics associated with switching to systemic treatments., Methods: Data were extracted from the Child-CAPTURE registry, a prospective, observational cohort of patients with paediatric-onset psoriasis followed into young adulthood from 2008 to 2018. Data prior to inclusion in the registry were collected retrospectively. Median times were determined through Kaplan-Meier survival analyses. Cox regression analysis was used to identify patient characteristics associated with switch to systemic treatment., Results: Of 448 patients, 62·3% stayed on solely topical treatment until data lock; 14·3% switched from topicals to phototherapy, but not to systemic treatment; and 23·4% switched to systemic treatment. The median time from psoriasis onset until discontinuation of solely topical treatment was 7·3 years, and until switch to systemics was 10·8 years. Higher Psoriasis Area and Severity Index and (Children's) Dermatology Life Quality Index > 5 were independently associated with switching to systemic treatment., Conclusions: In a population of paediatric and adolescent patients with mild-to-severe psoriasis, one-third needed more intensive treatment than solely topical therapy to control their disease. We consider the median time until switching to systemics to be long., (© 2020 The Authors.

Purpose: The purpose of this study was to evaluate the functional relevance of longitudinal changes in hyperautofluorescent areas and flecks in Stargardt disease (STGD1) using short-wavelength autofluorescence (SW-AF) imaging., Methods: In this prospective, longitudinal study, 31 patients with STGD1 (56 eyes) underwent microperimetry (MP) and SW-AF imaging twice in 3 to 5 years. A total of 760 MP test points were included in the statistical analysis based on stable fixation and accurate alignment of SW-AF and MP. Autofluorescence intensity was qualitatively assessed in all MP test points. Small circumscriptive hyperautofluorescent lesions were defined as flecks. Longitudinal imaging characteristics observed on SW-AF were classified into the following categories: appearing, disappearing, and stable flecks, stable hyperautofluorescent, and stable background autofluorescence. The relationship between SW-AF intensity changes and MP changes was analyzed using a linear mixed model corrected for baseline sensitivity., Results: Retinal sensitivity declined most in locations without change in SW-AF intensity. Functional decline per year was significantly larger in flecks that disappeared (-0.72 ± 1.30 dB) compared to flecks that appeared (-0.34 ± 0.65 dB), if baseline sensitivity was high (≥10 dB; P < 0.01). The correlation between the change observed on SW-AF and the sensitivity change significantly depended on the sensitivity at baseline (P = 0.000)., Conclusions: Qualitative longitudinal assessment of SW-AF poorly reflected the retinal sensitivity loss observed over the course of 3 to 5 years., Translational Relevance: When aiming to assess treatment effect on lesion level, a multimodal end point including MP focused on hyperautofluorescent lesions appears essential but needs further studies on optimizing MP grids, eye-tracking systems, and alignment software.

Background: The rising incidence rates of skin cancer (SC) lead to an enormous burden on healthcare systems. General practitioners (GPs) might play an important part in SC care, but research has shown poor clinical recognition of SC, leading to a high rate of potentially unnecessary referrals., Objectives: The aim of this study was to evaluate if a dermato-oncological training programme (DOTP) for GPs improved their diagnostic skills and quality of referrals., Methods: Out of 194 GPs in the Nijmegen area, 83 (42·8%) followed a DOTP on SC. Referrals from both a trained cohort (TC) and two cohorts of untrained GPs [untrained present cohort (UPC) and untrained historical cohort (UHC)] were included. Data on diagnostic skills, quality of referrals and the number of potentially unnecessary referrals were evaluated., Results: A total number of 1662 referrals were analysed. The referral diagnosis was correct more often in the TC (70·3%) compared with the UPC (56·2%; P < 0·001) and the UHC (51·6%; P < 0·001). Furthermore, the TC also provided a better lesion description, mentioned a diagnosis more often in their referral letters and more often performed diagnostics before referral. In addition, fewer potentially unnecessary referrals were identified in the TC compared with the UPC (62·7% vs. 73·7%; P < 0·001) and the UHC (75·2%; P < 0·001)., Conclusions: GPs who followed a DOTP had better diagnostic skills and quality of referrals than untrained GPs, leading to fewer potentially unnecessary referrals. This might enhance a more efficient use of the limited capacity in secondary dermatological care and consequently lead to lower healthcare costs., (© 2020 Radboudumc.

Background: Female sex has been reported as a predictor for treatment discontinuation with biological therapies for psoriasis, although reasons remain unclear. It can be hypothesized that lower satisfaction with biological treatment in women might add to the lower drug survival rates., Objectives: To identify possible differences in satisfaction with biological treatment between female and male patients using the Treatment Satisfaction Questionnaire for Medication (TSQM)., Methods: Data of psoriasis patients treated with biologics were obtained from the prospective, multicentre, daily-practice BioCAPTURE registry. Longitudinal TSQM data were analysed by linear mixed models. Relevant patient characteristics were incorporated as possible confounding factors. Post hoc analysis of adverse events was performed in order to investigate differences between sexes., Results: We included 315 patients with 396 corresponding treatment episodes (137 adalimumab, 90 etanercept, 137 ustekinumab, 24 secukinumab and 8 infliximab). Almost forty per cent of the patients were female. Women had significantly lower baseline PASI scores (P = 0.01). Longitudinal analyses demonstrated lower TSQM scores for 'side-effects' (P = 0.05) and 'global satisfaction' (P = 0.01) in female patients compared with male patients over 1 year of treatment. Women reported more relevant adverse events in the context of biologic treatment compared to men (rate ratio 1.79; P < 0.001), with more fungal (rate ratio 2.20; P = 0.001) and herpes simplex infections (rate ratio 3.25; P = 0.005)., Conclusions: This study provides a prospective, longitudinal analysis of treatment satisfaction with biologics in female and male patients with psoriasis. Women were slightly less satisfied with treatment regarding side-effects and global satisfaction. Differences in treatment satisfaction and side-effects might add to the fact that women discontinue biological treatments more often., (© 2019 European Academy of Dermatology and Venereology.)

Purpose: Chronic central serous chorioretinopathy (cCSC) is characterized by fluid accumulation between photoreceptors and the retinal pigment epithelium of which the cause is unknown. Associations with steroid use, stress, pregnancy, and the male sex suggest a role for the steroid hormone system in the disease. Here, we performed a comprehensive analysis of the steroid hormone system in active cCSC., Methods: Serum hormone levels of 17 steroid hormones were measured in 46 male Caucasian patients with active cCSC and 46 male Caucasian age-matched controls using the AbsoluteIDQ stero17 kit., Results: Elevated levels of androsterone, estrone, etiocholanolone, and androstenedione were observed in cCSC patients compared with controls. Median hormone levels in cCSC patients versus controls, respectively, were as follows: androsterone, 0.84 ng/mL (interquartile range [IQR] = 0.61-1.06) versus 0.69 ng/mL (IQR = 0.48-0.96, P = 0.031); estrone, 0.12 ng/mL (IQR = 0.10-0.15) versus 0.10 ng/mL (IQR = 0.08-0.11; P = 0.0048); etiocholanolone, 0.19 ng/mL (IQR = 0.15-0.29) versus 0.13 ng/mL (IQR = 0.099-0.20, P = 0.0061). Mean levels of androstenedione were 3.10 ng/ml (SD = 1.03) versus 2.55 ng/mL (SD = 0.95), in cCSC patients versus controls, respectively. Additionally, Spearman's correlations between aldosterone and 11-deoxycortisol, androsterone, DHEA, DHEAS, and E1 differed between cCSC patients and controls, as well as between andosterone and E1, and between DHT and 17OHP., Conclusions: We present a comprehensive overview of the status of the steroid hormone system in active cCSC. Levels of four hormones were elevated in cCSC patients compared with controls, and the relationships between steroid hormones was altered, indicating that the balance in the steroid hormone system is altered in cCSC patients.

Age-related macular degeneration (AMD) is a common, progressive multifactorial vision-threatening disease and many genetic and environmental risk factors have been identified. The risk of AMD is influenced by lifestyle and diet, which may be reflected by an altered metabolic profile. Therefore, measurements of metabolites could identify biomarkers for AMD, and could aid in identifying high-risk individuals. Hypothesis-free technologies such as metabolomics have a great potential to uncover biomarkers or pathways that contribute to disease pathophysiology. To date, only a limited number of metabolomic studies have been performed in AMD. Here, we aim to contribute to the discovery of novel biomarkers and metabolic pathways for AMD using a targeted metabolomics approach of 188 metabolites. This study focuses on non-advanced AMD, since there is a need for biomarkers for the early stages of disease before severe visual loss has occurred. Targeted metabolomics was performed in 72 patients with early or intermediate AMD and 72 control individuals, and metabolites predictive for AMD were identified by a sparse partial least squares discriminant analysis. In our cohort, we identified four metabolite variables that were most predictive for early and intermediate stages of AMD. Increased glutamine and phosphatidylcholine diacyl C28:1 levels were detected in non-advanced AMD cases compared to controls, while the rate of glutaminolysis and the glutamine to glutamate ratio were reduced in non-advanced AMD. The association of glutamine with non-advanced AMD corroborates a recent report demonstrating an elevated glutamine level in early AMD using a different metabolomics technique. In conclusion, this study indicates that metabolomics is a suitable method for the discovery of biomarker candidates for AMD. In the future, larger metabolomics studies could add to the discovery of novel biomarkers in yet unknown AMD pathways and expand our insights in AMD pathophysiology., Competing Interests: The commercial affiliation of S.F. to La Roche AG does not alter our adherence to PLOS ONE policies on sharing data and materials.

Several prediction models for progression of age-related macular degeneration (AMD) have been developed, but the added value of using genetic information in those models in addition to clinical characteristics is ambiguous. In this prospective cohort study, we explored the added value of genetics using a genetic risk score (GRS) based on 52 AMD-associated variants, in addition to the clinical severity grading at baseline as quantified by validated drusen detection software, to predict disease progression in 177 AMD patients after 6.5 years follow-up. The GRS was strongly associated with the drusen coverage at baseline (P < 0.001) and both the GRS and drusen coverage were associated with disease progression. When the GRS was added as predictor in addition to the drusen coverage, R 2 increased from 0.46 to 0.56. This improvement by the GRS was predominantly seen in patients with a drusen coverage <15%. In patients with a larger drusen coverage, the GRS had less added value to predict progression. Thus, genetic information has added value over clinical characteristics in predicting disease progression in AMD, but only in patients with a less severe disease stage. Patients with a high GRS should be made aware of their risk and could be selected for clinical trials for arresting progression.

Purpose: To investigate the relationship between baseline number of hyperreflective foci (HF) on spectral domain optical coherence tomography (SD-OCT) in patients with diabetic macular edema (DME), as well as the dynamics of HF during treatment with anti-vascular endothelial growth factor (VEGF), and treatment response., Methods: We evaluated patients diagnosed with DME scheduled for treatment with intravitreal bevacizumab. Eyes were classified as adequate or insufficient treatment responders based on logMAR visual acuity improvement and central retinal thickness (CRT) decrease after three consecutive injections. Associations between number of HF at baseline and treatment response, the change in HF over the course of treatment, and the distribution of HF within the retinal layers were evaluated., Results: In 54 eyes of 41 patients, mean number of HF and CRT decreased after intravitreal treatment with bevacizumab (p = 0.002 and p<0.001 respectively). Decrease in CRT after 3 months was independently associated with a higher number of HF at baseline (estimated effect -2.61, 95% CI [-4.42--0.31], p = 0.006). Eyes with adequate treatment response presented with more HF at baseline (OR 1.106, 95% CI [1.012-1.210], p = 0.030) than eyes with insufficient treatment response. Most HF were located within the inner retinal layers, and decrease of HF was mostly due to a decrease of inner retinal HF., Conclusions: In patients with DME treated with anti-VEGF, higher baseline numbers of HF have predictive value for treatment response in terms of visual acuity improvement and CRT decrease after 3 months. In addition, HF were responsive to anti-VEGF therapy., Competing Interests: The authors have declared that no competing interests exist.

Purpose: To compare the anatomic and functional efficacy and safety of half-dose photodynamic therapy (PDT) versus high-density subthreshold micropulse laser (HSML) treatment in patients with chronic central serous chorioretinopathy (cCSC)., Design: Open-label, multicenter, randomized controlled clinical trial., Participants: Patients with cCSC whose disease had to be confirmed by both clinical characteristics and findings on multimodal imaging., Methods: Eligible patients were randomized in a 1:1 allocation ratio. Treatment was evaluated during a follow-up visit, and the same treatment was repeated in patients who still demonstrated subretinal fluid (SRF)., Main Outcome Measures: The primary end point was the complete disappearance of SRF at the first evaluation visit at 6 to 8 weeks after treatment. As a secondary outcome measure, we assessed this anatomic result at the final evaluation visit at 7 to 8 months after treatment. Other secondary outcomes covered functional improvement and included change in best-corrected visual acuity (BCVA; measured in Early Treatment Diabetic Retinopathy Study [ETDRS] letters), retinal sensitivity (measured using microperimetry), and vision-related quality of life using a validated questionnaire., Results: Between November 2013 and September 2016, 179 patients were included: 89 patients were assigned randomly to half-dose PDT, and 90 were assigned randomly to HSML treatment. At their first evaluation visit, SRF had resolved in 51.2% and 13.8% of patients, respectively (P < 0.001). At their final evaluation visit, a significantly higher percentage of PDT-treated patients demonstrated no SRF (67.2% vs. 28.8%; P < 0.001). Moreover, at the first evaluation visit, the PDT-treated patients showed a significantly higher increase in BCVA (+4.60±6.62 ETDRS letters vs. +1.39±8.99 ETDRS letters; P = 0.011), and a significantly higher increase in retinal sensitivity on microperimetry (+2.01±3.04 dB vs. +0.92±3.65 dB; P = 0.046); however, the improvement in vision-related quality of life was similar (score of +2.87±8.35 vs. +2.56±7.36, respectively; P = 0.800)., Conclusions: Half-dose PDT is superior to HSML for treating cCSC, leading to a significantly higher proportion of patients with complete resolution of SRF and functional improvement., (Copyright © 2018 American Academy of Ophthalmology.

Purpose: To investigate risk factors for the development and progression of diabetic retinopathy (DR) and long-term visual outcomes in Dutch patients with type 1 diabetes mellitus (T1DM)., Methods: Cumulative incidences were calculated for DR, vision-threatening DR (VTDR), defined as (pre)proliferative DR and diabetic macular oedema, and best-corrected visual acuity (BCVA) <0.5 and <0.3 at the most recent eye examination. The following factors were assessed: duration of diabetes, age of onset of T1DM, gender, mean HbA1c, HbA1c variability (defined as coefficient of variation of five separate HbA1c measurements), mean arterial blood pressure, body mass index, albuminuria and lipid profile. We used multivariable Cox regression models to identify factors associated with DR development and progression to VTDR., Results: We found 25-year cumulative incidences of 63% for DR, 21% for VTDR, 2% for BCVA <0.5, and 1% for BCVA <0.3. Mean HbA1c (HR 1.023, p < 0.001), HbA1c variability (HR 1.054, p < 0.001), age of onset of T1DM (HR 1.024, p < 0.001), HDL cholesterol (HR 0.502, p = 0.002) and total cholesterol (HR 1.210, p = 0.029) showed an independent association with faster development of any form of DR. The mean HbA1c (HR 1.023, p < 0.001) and the presence of albuminuria (HR 2.940, p = 0.028) were associated with faster progression to VTDR., Conclusion: These data show relatively low cumulative incidences of DR, VTDR and visual impairment. Higher mean HbA1c, HbA1c variability, age of onset of T1DM and total cholesterol were independently associated with the risk of DR development, and a protective association was found for HDL cholesterol in subjects with T1DM. Mean HbA1c and presence of albuminuria were associated with progression of DR., (© 2018 The Authors.

Purpose: The CONDOR study showed that docetaxel/cisplatin/5-fluorouracil (TPF) followed by conventional radiotherapy with cisplatin 100 mg/m 2 on days 1, 22, and 43 (cis100 + RT; n = 27)) versus accelerated radiotherapy with cisplatin weekly 40 mg/m 2 (cis40 + ART; n = 29) in locally advanced head and neck cancer (LAHNC) patients was not feasible. Here, we report the analysis of health-related quality of life (HRQOL) of the patients entered in this study., Methods: HRQOL was assessed at baseline, after two TPF, before start of chemoradiotherapy, and 1, 4, 8, 12, and 24 months after completion of chemoradiotherapy using the EORTC-QLQ-C30 and QLQ-H&N35 in 62 patients., Results: Compliance with the QOL questionnaires was 94% (59/62) at baseline and 61% (30/49) at 12 months, respectively. HRQOL decreased after TPF and further decreased during chemoradiohteray in both arms equally. Pain and swallowing dysfunction improved significantly during TPF but deteriorated below baseline levels during chemoradiotherapy, cis40 + ART > cis100 + RT (p < 0.05). HRQOL and symptoms restored to baseline within 12 months in both arms and remained at that level until 24 months., Conclusions: After TPF, cis40 + ART had a larger negative impact on symptoms than cis100 + RT, probably due to the ART. HRQOL and symptoms restored to baseline levels within 12 months after end of treatment in both arms, which is an important perspective for patients during the phase of most serious acute side effects of treatment., Trial Registration: NCT00774319.

Purpose: A recent genome-wide association study by the International Age-related Macular Degeneration Genomics Consortium (IAMDGC) identified seven rare variants that are individually associated with age-related macular degeneration (AMD), the most common cause of vision loss in the elderly. In literature, several of these rare variants have been reported with different frequencies and odds ratios across populations of Europe and North America. Here, we aim to describe the representation of these seven AMD-associated rare variants in different geographic regions based on 24 AMD studies., Methods: We explored the occurrence of seven rare variants independently associated with AMD ( CFH rs121913059 (p.Arg1210Cys), CFI rs141853578 (p.Gly119Arg), C3 rs147859257 (p.Lys155Gln), and C9 rs34882957 (p.Pro167Ser)) and three non-coding variants in or near the CFH gene (rs148553336, rs35292876, and rs191281603) in 24 AMD case-control studies. We studied the difference in distribution, interaction, and effect size for each of the rare variants based on the minor allele frequency within the different geographic regions., Results: We demonstrate that two rare AMD-associated variants in the CFH gene (rs121913059 [p.Arg1210Cys] and rs35292876) deviate in frequency among different geographic regions (p=0.004 and p=0.001, respectively). The risk estimates of each of the seven rare variants were comparable across the geographic regions., Conclusions: The results emphasize the importance of identifying population-specific rare variants, for example, by performing sequencing studies in case-control studies of various populations, because their identification may have implications for diagnostic screening and personalized treatment.

Background: The efficacy of etanercept and ustekinumab in psoriasis has been compared in one randomized controlled trial. Comparison of the long-term effectiveness of biologics in daily-practice psoriasis treatment is currently lacking., Objectives: To compare the effectiveness between the three widely used outpatient biologics adalimumab, etanercept and ustekinumab in daily-practice psoriasis treatment and to correct for confounders., Methods: Data were extracted from the prospective, multicentre BioCAPTURE registry. Multilevel linear regression analyses (MLRAs) and generalized estimating equation (GEE) analyses were performed on the course of mean Psoriasis Area and Severity Index (PASI) and PASI 75 (≥ 75% reduction vs. baseline). Both models were corrected for confounders. Subgroup analyses for biological dose were performed., Results: We included 356 patients with 513 treatment episodes: 178 adalimumab, 245 etanercept and 90 ustekinumab. MLRA showed a similar effectiveness between adalimumab, etanercept and ustekinumab after 1 year, but the highest effectiveness for ustekinumab during 5 years of treatment (P = 0·047; ustekinumab vs. etanercept, P = 0·019). GEE analysis revealed a higher chance of attaining PASI 75 with adalimumab and ustekinumab than with etanercept at 1 year of treatment. A higher than label dose was more often used in patients treated with etanercept (adalimumab, etanercept and ustekinumab: respectively 31·5%, 55·1% and 17% after 1 year, P < 0·001; 39·3%, 71·4% and 24% after 5 years, P < 0·001)., Conclusions: Compared with etanercept, ustekinumab had the highest effectiveness during 5 years of treatment. Patients receiving adalimumab and ustekinumab more often reached PASI 75 than those on etanercept at 1 year of treatment. Dose escalation was more frequent in etanercept and adalimumab than in ustekinumab., (© 2016 British Association of Dermatologists.)

The complement system is the first line of defense against foreign intruders, and deregulation of this system has been described in multiple diseases. In age-related macular degeneration (AMD), patients have higher complement activation levels compared to controls. Recently, a combination of three single nucleotide polymorphisms (SNPs) in genes of the complement system, referred to as a complotype, has been described to increase complement activation in vitro. Here we describe a novel complotype composed of CFB (rs4151667)-CFB (rs641153)-CFH (rs800292), which is strongly associated with both AMD disease status (p = 5.84*10(-13)) and complement activation levels in vivo (p = 8.31*10(-9)). The most frequent genotype combination of this complotype was associated with the highest complement activation levels in both patients and controls. These findings are relevant in the context of complement-lowering treatments for AMD that are currently under development. Patients with a genetic predisposition to higher complement activation levels will potentially benefit the most of such treatments.

Background: Actinic keratoses (AKs) are often treated separately, lesion by lesion. However, in the past years, AKs have been described as a field disease and not limited to single clinically apparent lesions. Treatment should therefore target an area of field change which may reduce the risk of development of further AKs, second tumours, and local recurrence., Objective: The primary objective was to determine the number of new lesions at 9 months after methyl aminolevulinate photodynamic therapy (MAL-PDT). Secondary objectives were to determine the number of new lesions at 3 and 6 months after treatment and the percentage reduction of AKs from baseline at 3, 6, and 9 months after MAL-PDT., Methods: This was a single-centre, prospective, randomized, split-face, investigator-blinded pilot study with a study duration of 1 year. The study population comprised patients with AKs on the face or scalp, with a maximum of 10 AKs on each side. One side was treated with 1 session of "lesion-by-lesion" MAL-PDT (LT side) and the other side with 1 session of field MAL-PDT (FT side)., Results: At 9 months the FT demonstrated significantly fewer new lesions. At every time point during the follow-up, we found a significant reduction in the number of AKs in the LT as well as in the FT sides. After 3 and 6 months we did not observe significant differences between the sides. However, after 9 months, the LT area showed significantly fewer remaining AKs, whereas the FT area demonstrated significantly fewer new lesions., Conclusions: Field treatment results in significantly fewer new AK lesions compared with lesion-by-lesion treatment., (© 2017 S.
