The socio-economic burden of H1-antihistamine-refractory chronic spontaneous urticaria in Germany.

BACKGROUND AND STUDY AIM: Data from the AWARE study (A Worldwide Antihistamine-Refractory chronic urticaria patient Evaluation) illustrate a substantial disease burden in German patients with H1-antihistamine (-H1-AH)-refractory chronic spontaneous urticaria (CSU). Detrimental effects on patients' quality of life, poor disease control and impairment in the ability to work and perform other daily activities are reported. Based on these findings, this study aims to quantify the epidemiological and socio-economic burden of H1-AH-refractory CSU in Germany. METHODS: To determine the epidemiological burden of H1-AH-refractory CSU, the age- and gender-specific prevalence of CSU and the proportion of H1-AH-refractory patients in Germany anonymized data from the InGef research database have been used. In a second step, the socio-economic burden in terms of lost numbers of hours in paid and unpaid work was calculated by extrapolating the age- and gender-specific work productivity and activity impairment (WPAI) observed in AWARE to the H1-AH-refractory CSU population in Germany. Finally, productivity losses in paid and unpaid work were monetized using the human capital and the friction cost approach respectively. Moreover, socio-economic burden was calculated depending on symptom control of the patients (measured by urticaria control test [UCT]). RESULTS: In Germany, over 203,000 patients (20 years or older) had H1-AH-refractory CSU in 2018. The avoided lost paid and unpaid work hours attributable to H1-AH-refractory CSU summed up to over 100 million. Overall, the socio-economic burden of H1-AH-refractory CSU in monetary terms was evaluated at € 2.2 billion and the majority of this was due to unpaid work loss. Patients with poor disease control, as indicated by UCT score < 12, were more likely to suffer from high impairment than patients with controlled disease, resulting in a higher socio-economic burden. CONCLUSION: The results of our analyses picture the substantial socio-economic burden of H1-AH-refractory CSU and therefore the tremendous impact it has on daily lives of individuals and society overall.

Modelling of patient journey in chronic spontaneous urticaria: Increasing awareness and education by shorten patients' disease journey in Germany.

BACKGROUND: Chronic spontaneous urticaria (CSU) is both physically and emotionally stressful, and guideline recommendations are often not optimally implemented in clinical practice. The objective of this study was to provide an overview on the patient journey in CSU and to develop a mathematical model based on solid data. METHODS: The journey of CSU patients in Germany was traced through literature review and expert meetings that included medical experts, pharmacists and representatives of patient organizations. The current situation's main challenges in the patient journey (education, collaboration and disease management) were discussed in depth. Then, a probabilistic model was developed in a co-creation approach to simulate the impact of three potential improvement strategies: (1) patient education campaign, (2) medical professional education programme and (3) implementation of a disease management programme (DMP). RESULTS: Chronic spontaneous urticaria patients are severely burdened by delays in diagnosis and optimal medical care. Our simulation indicates that in Germany, it takes on average of 3.8 years for patients to achieve disease control in Germany. Modelling all three optimization strategies resulted in a reduction to 2.5 years until CSU symptom control. On a population level, the proportion of CSU patients with disease control increased from 44.2% to 58.1%. CONCLUSION: In principle, effective CSU medications and a disease-specific guideline are available. However, implementation of recommendations is lagging in practice. The approach of quantitative modelling of the patient journey validates obstacles and shows a clear effect of multiple interventions on the patient journey. The data generated by our simulation can be used to identify strategies for improving patient care. Our approach might helping in understanding and improving the management of patients beyond CSU.

Real-world effectiveness and safety of tildrakizumab in long-term treatment of plaque psoriasis: Results from the non-interventional, prospective, multicentre study TILOT.

BACKGROUND: Plaque psoriasis is a chronic inflammatory disorder affecting the skin and impacting quality of life. Tildrakizumab (TIL) is an IL-23 inhibitor licensed for moderate-to-severe plaque psoriasis. Regulatory approval of medicinal products is based on safety and efficacy data from randomized controlled trials (RCTs) which impose stringent selection criteria. Long-term non-interventional studies (NIS) are needed to establish effectiveness and safety in daily practice bridging the gap between RCTs and the real-world setting. OBJECTIVES: This analysis of the NIS TILOT seeks to evaluate effectiveness and safety of TIL in patients with moderate-to-severe plaque psoriasis in a real-world setting. Secondary objectives include the assessment of the Dermatology Life Quality Index (DLQI), treatment satisfaction and course of scalp and nail disease using Physician Global Assessment (PGA). METHODS: Interim analysis at 52 weeks (W) of the ongoing non-interventional, prospective, long-term multicentre study TILOT. RESULTS: The effectiveness analysis included 412 patients. The mean [standard deviation, SD] Psoriasis Area and Severity Index (PASI) score was 16.0 [9.1] at baseline improving by 82.4% (95% confidence interval [CI], 78.9-86.0) to 2.1 [2.9] at W52. The proportion of patients achieving PASI scores of <3 and <5 increased over time peaking at 74.6% (95% CI, 69.3-79.4) and 88.4% (95% CI, 84.3-91.8) at W52. Scalp-PGA and nail-PGA improved by 79.8% (95% CI, 75.6-84.0) and 72.7% (95% CI, 63.9-81.6), respectively. DLQI of 0/1 was achieved by 48.2% (95% CI, 42.3-54.2). Nine out of 10 physicians and patients expressed a high level of treatment satisfaction. No new safety signals were observed. CONCLUSIONS: This prospective cohort study demonstrates a high degree of effectiveness and a reassuring safety profile of TIL in a real-world setting over 52 weeks. Patients with scalp and nail involvement or pruritus showed marked improvements.

Perception of the coronavirus pandemic by patients with atopic dermatitis - Results from the TREATgermany registry.

BACKGROUND: TREATgermany, a registry for patients with moderate to severe atopic dermatitis (AD), established an additional questionnaire in spring 2020 to investigate the effects of the coronavirus pandemic on the daily life of patients with AD. MATERIAL AND METHODS: A questionnaire was used to analyze general information regarding a patient's experience of the coronavirus pandemic and, using the Inventory of Life-Changing Events, the resulting personal burden. To analyze possible associations between disease severity (EASI score, oSCORAD, IGA, PGA, POEM), quality of life (DLQI) and personal burden, t-tests, analyses of variance and correlations were evaluated, controlled for sex and age. RESULTS: 58 % (n = 233) of the included 400 registry patients reported high burden scores caused by the coronavirus pandemic, regardless of an actual infection. Men showed significantly higher burden scores than women, and younger than older respondents (both P = 0.03). There were no differences in burden scores related to the physician's assessment of disease severity. However, patients with higher quality of life impairments and higher disease severity perceived the burden of the coronavirus pandemic as less severe (DLQI P = 0.019, PGA P = 0.044). CONCLUSIONS: Our data show that registry patients considered the coronavirus pandemic as a life-changing event and perceived the burden differently. This should be taken into account in the treatment of patients with moderate to severe AD as well as in further studies.

Documentation of psoriasis in routine care - expert consensus on a German data set.

BACKGROUND AND OBJECTIVES: Documenting patient data in psoriasis clinical practice can improve care, but standardized and transparent documentation is rare. The current project aimed to develop a data set for the documentation of psoriasis in daily practice. MATERIAL AND METHODS: In four online Delphi rounds and one in-person meeting, 27 psoriasis experts allocated variables to a standard, an optimal and an optional data set. Most of the questions were standardized. Open questions were included to allow for the provision of reasons and to enlarge the data sets. Furthermore, in the in-person meeting we considered a) patients' attitudes and b) dermatologists' information on the current usage and acceptability in Germany. RESULTS: The consensus approach resulted in a data set with 69 variables. The standard data set includes 20, the optimal data set 31 and the optional data set 18 variables. In summary, the data set can mainly be grouped into master data, general status and medical history data, medical history of psoriasis, status of psoriasis, diagnostics and comorbidity, therapies and patient-reported outcomes. CONCLUSIONS: The consensus recommendation of a standard, an optimal and an optional data set for routine care of psoriasis intends to be a decision-making aid and an orientation for both daily practice and further development of documentation systems.

Quality-of-Life Outcomes, Effectiveness and Tolerability of Apremilast in Patients with Plaque Psoriasis and Routine German Dermatology Care: Results from LAPIS-PSO.

INTRODUCTION: Psoriasis is a systemic inflammatory disease characterised by pruritic skin lesions that impair quality of life (QOL). Long-Term Documentation of the Utilization of Apremilast in Patients with Plaque Psoriasis under Routine Conditions (LAPIS-PSO; ClinicalTrials.gov: NCT02626793) was a 52-week, prospective, multicentre, observational cohort study conducted in real-world dermatology clinical settings in Germany. We evaluated physician- and patient-reported outcomes for QOL, effectiveness and tolerability in patients with moderate to severe psoriasis vulgaris in LAPIS-PSO. METHODS: The primary endpoint was the percentage of patients achieving Dermatology Life Quality Index (DLQI) score ≤ 5 or ≥ 5-point improvement from baseline in DLQI score at visit 2 (~ 4 months after baseline). Secondary endpoints included assessments of symptoms and disease severity. Tolerability was evaluated based on adverse events (AEs). A pre-defined subgroup analysis based on baseline Physician's Global Assessment (PGA) score (2 or 3 versus 4) was performed. Data were examined descriptively through visit 5 (~ 13 months) using the last-observation-carried-forward (LOCF) approach and data as observed. RESULTS: In total, 257 patients were included for efficacy assessment. On LOCF analysis, most patients achieved the primary endpoint at visit 2 (66.5%); DLQI response was maintained at visit 5 (72.4%). Earlier treatment response was observed in patients with a PGA score of 2 or 3 versus 4 (visit 1 PASI ≤ 3: 20.5% versus 10.8%). Adverse events were consistent with the known safety profile of apremilast. CONCLUSIONS: In routine clinical care in Germany, patients with moderate to severe plaque psoriasis benefited from apremilast treatment up to ~ 13 months, consistent with findings from clinical trials, with a good safety profile.

Expert consensus on practical aspects in the treatment of chronic urticaria.

BACKGROUND: Chronic urticaria (CU) is a common disease which represents a considerable burden for many patients. The current urticaria guideline describes the evidence-based diagnosis and treatment of CU. In addition, however, questions often arise in everyday practice that are not addressed by the guideline. METHODS: In May 2020, a digital meeting with German urticaria experts was held, in which practical aspects of CU treatment were discussed and supporting aids for everyday clinical treatment formulated. The resulting advice in this document focus on practical questions and the available literature and experiences of the participants. RESULTS: The diagnosis of CU can be made in a short time by means of a thorough anamnesis, a physical examination, and a basic laboratory chemical diagnosis. For this purpose, practical recommendations for everyday practice are given in this paper. An extended diagnosis is only indicated in a few cases and should always be carried out in parallel with an effective therapy. In general, CU should always be treated in the same way, regardless of whether wheals, angioedema or both occur. Symptomatic therapy should be carried out according to the treatment steps recommended by the guidelines. This publication provides practical advice on issues in everyday practice, such as the procedure in the current coronavirus disease 2019 (COVID-19) pandemic, the cardiac risk under higher dosed H1 antihistamines, the self-administration of omalizumab as well as vaccination under omalizumab therapy. In addition to treatment recommendations, topics such as documentation in the practice and family planning with urticaria will be discussed. DISCUSSION: These supporting treatment recommendations serve as an addendum to the current CU guideline and provide support in dealing with CU patients in everyday practice. The aim is to ensure that patients suffering from CU achieve complete freedom of symptoms with the help of an optimal therapy.
