Skin and respiratory ill-health attributed to occupational face mask use.

BACKGROUND: Face mask use in the workplace has become widespread since the onset of the Covid-19 pandemic and has been anecdotally linked to adverse health consequences. AIMS: To examine reports of adverse health consequences of occupational face mask use received by The Health and Occupation Research (THOR) network before and after the pandemic onset. METHODS: THOR databases were searched to identify all cases of ill-health attributed to 'face mask' or similar suspected causative agent between 1 January 2010 and 30 June 2021. RESULTS: Thirty two cases were identified in total, 18 reported by occupational physicians and 14 by dermatologists. Seventy-five per cent of cases were reported after the pandemic onset and 91% cases were in the health and social care sector. 25 of the 35 (71%) diagnoses were dermatological, the most frequent diagnoses being contact dermatitis (14 cases) and folliculitis/acne (6 cases). Of the seven respiratory diagnoses, four were exacerbation of pre-existing asthma. CONCLUSIONS: There is evidence of an abrupt increase in reports of predominantly dermatological ill-health attributed to occupational face mask use since the start of the pandemic. Respiratory presentations have also occurred.

Alcohol misuse is associated with poor response to systemic therapies for psoriasis: findings from a prospective multicentre cohort study.

BACKGROUND: Factors that might influence response to systemic treatment for moderate-to-severe psoriasis are varied, and generally, are poorly understood, aside from high bodyweight, suggesting that other unidentified factors may be relevant in determining response to treatment. The impact of alcohol misuse on treatment response has not been previously investigated. OBJECTIVES: To investigate whether alcohol misuse is associated with poor response to treatment for psoriasis. METHODS: This was a prospective cohort study in which response to systemic therapies was assessed using the Psoriasis Area and Severity Index (PASI). The CAGE (Cut down, Annoyed, Guilty, Eye opener) questionnaire was used to screen for alcohol misuse. A multivariable factional polynomial linear regression model was used to examine factors associated with change in PASI between baseline and follow-up. RESULTS: The cohort comprised 266 patients (biologic cohort, n = 134; conventional systemic cohort, n = 132). For the entire cohort, the median (interquartile range) PASI improved from 13 (10·0-18·3) at baseline to 3 (1·0-7·5) during follow-up. A higher CAGE score [regression coefficient: 1·40, 95% confidence interval (CI) 0·04-2·77]; obesity (1·84, 95% CI 0·48-3·20); and receiving a conventional systemic rather than a biologic therapy (4·39, 95% CI 2·84-5·95) were significantly associated with poor response to treatment; whereas a higher baseline PASI (-0·83, 95% CI -0·92 to -0·74) was associated with a better response to treatment. CONCLUSIONS: The poor response to therapy associated with alcohol misuse and obesity found in people with psoriasis calls for lifestyle behaviour change interventions and support as part of routine clinical care. Targeting interventions to prevent, detect and manage alcohol misuse among people with psoriasis is needed to minimize adverse health consequences and improve treatment response.

Systematic review examining changes over time and variation in the incidence and prevalence of psoriasis by age and gender.

BACKGROUND: There is a lack of any overview of changes over time and variation in the epidemiology of psoriasis with age and between genders. OBJECTIVES: To perform a systematic review of published population-based studies on variations in psoriasis incidence and prevalence with age and between genders, and to explore trends in psoriasis epidemiology over time. METHODS: Eleven electronic and regional databases were searched from their inception dates to October 2019. No language restrictions were applied. Studies were eligible if they reported on changes in psoriasis incidence and/or prevalence over time and/or by age group and gender. RESULTS: In total 308 papers were critically appraised, from which 90 studies from 22 countries were included. Incidence data confirmed a clear bimodal age pattern in psoriasis onset, with the first and second peaks at around 30-39 and 60-69 years of age, respectively, and evidence suggesting that it presents slightly earlier in women than in men. Prevalence data showed an increasing trend with age until around 60 or 70 years, after which it decreases. Although there was lack of agreement on specific gender differences in psoriasis incidence and prevalence, a slight male predominance was reported in several studies. Studies worldwide suggested a stable or slightly decreasing trend in psoriasis incidence, while an increasing trend in psoriasis prevalence has been consistently reported. One particular challenge faced was the vastly different methodologies used in the included studies, which contributed to some of the heterogeneity of the results. CONCLUSIONS: Studies on changes over time in the occurrence of psoriasis have contributed to a greater appreciation of the increasing burden of the disease. However, further research is required to determine the reasons driving the increase in psoriasis prevalence over time.

Incidence and prevalence of psoriasis in Israel between 2011 and 2017.

BACKGROUND: Psoriasis is a common chronic inflammatory skin disease associated with a heavy burden of morbidity, disability and cost. The occurrence of the disease in Israel has not been previously investigated. OBJECTIVES: To provide standardized estimates of trends in psoriasis incidence, prevalence and mortality among patients in Israel between 2011 and 2017. METHODS: Using electronic health records from Clalit Health Services, the largest nationwide public health provider in Israel, we conducted a population-based study investigating trends in the annual incidence and prevalence of psoriasis between the years 2011 and 2017. We report age- and sex-adjusted rates, using the standard European population as a reference. RESULTS: We identified 71 094 incident psoriasis cases. The mean (SD) age of onset was 42.4 (21.0) years with a bimodal distribution, peaking in the early '30s and early '60s. Late-onset psoriasis, occurring after 40 years of age, accounted for 51.1% of incident cases. The annual psoriasis incidence rate was constant throughout the study period (280/100 000 person-years). Psoriasis prevalence rose from 2.5% in 2011 to 3.8% in 2017. CONCLUSIONS: Psoriasis prevalence is increasing in Israel, although its incidence is stable. Clinicians and policymakers should plan to address the growing demands in the clinical, economic and societal burden of psoriasis.

Comparative effectiveness of biological therapies on improvements in quality of life in patients with psoriasis.

BACKGROUND: Evidence of the comparative effectiveness of biological therapies for psoriasis on health-related quality of life (HRQoL) in routine clinical practice is limited. OBJECTIVES: To examine the comparative effectiveness of adalimumab, etanercept and ustekinumab on HRQoL in patients with psoriasis, and to identify potential predictors for improved HRQoL. METHODS: This was a prospective cohort study in which changes in HRQoL were assessed using the Dermatology Life Quality Index (DLQI) and EuroQoL-5D (EQ-5D) at 6 and 12 months. Multivariable regression models were developed to identify factors associated with achieving a DLQI of 0/1 and improvements in the EQ-5D utility score. RESULTS: In total, 2152 patients with psoriasis were included, with 1239 patients on adalimumab, 517 on etanercept and 396 on ustekinumab; 81% were biologic naïve. For the entire cohort, the median (interquartile range) DLQI and EQ-5D improved from 18 (13-24) and 0·73 (0·69-0·80) at baseline to 2 (0-7) and 0·85 (0·69-1·00) at 6 months, respectively (P < 0·001). Similar improvements were achieved at 12 months. At 12 months, multivariable regression modelling showed that female sex, multiple comorbidities, smoking and a higher DLQI or a lower EQ-5D utility score at baseline predicted a lower likelihood of achieving a DLQI of 0/1 or improvement in the EQ-5D. Compared with adalimumab, patients receiving etanercept, but not ustekinumab, were less likely to achieve a DLQI of 0/1. There was no significant difference between the biological therapies in EQ-5D improvement. CONCLUSIONS: In routine clinical practice biological therapies produce marked improvement in HRQoL, which is influenced by the choice of biological therapy, baseline impairment in HRQoL, lifestyle characteristics and comorbidities. These findings should help inform selection of optimal biological therapy for patients related to improvements in HRQoL.

Patterns of biologic therapy use in the management of psoriasis: cohort study from the British Association of Dermatologists Biologic Interventions Register (BADBIR).

BACKGROUND: Treatment modifications, including dose escalations, dose reductions, switches, discontinuations and restarts of biologics may be necessary in the management of psoriasis but the patterns of usage are incompletely defined. OBJECTIVES: To examine the treatment utilization patterns of adalimumab, etanercept and ustekinumab among biologic-naïve and non-naïve patients with psoriasis enrolled in the British Association of Dermatologists Biologic Interventions Register (BADBIR). METHODS: The study cohort included adults with chronic plaque psoriasis who were followed up for ≥ 12 months. Treatment modifications were assessed during the first year of therapy. The time-trend method, comparing the cumulative dose (CD) patients received with the recommended cumulative dose (RCD), was used to assess dosing patterns. Concomitant use of other systemic treatments was also examined. RESULTS: In total, 2980 patients (adalimumab: 1675; etanercept: 996; ustekinumab: 309) were included; 79·2% were biologic-naïve. Over 12 months, 77·4% of patients continued the biologic, 2·6% restarted therapy after a break of ≥ 90 days, 2·5% discontinued, and 17·5% switched biologic therapy. Most patients (85·7%) received the RCD of the biologic, although 8·1% were exposed to a higher CD. In total, 749 (25·1%) patients used conventional systemic therapies concomitantly with a biologic at some stage; methotrexate was used most commonly (458; 61·2%). Of those using combination therapy, 454 (60·6%) continued the use of the conventional systemic therapy for > 120 days after the start of the biologic. CONCLUSIONS: More than one-third of patients experienced treatment modifications within the first year of initiating a biologic. Conventional systemic therapies, particularly methotrexate, were commonly used concurrently, which should be considered when evaluating treatment response and adverse events to biologics in real-world observational studies.

Demographics and disease characteristics of patients with psoriasis enrolled in the British Association of Dermatologists Biologic Interventions Register.

BACKGROUND: The British Association of Dermatologists Biologic Interventions Register (BADBIR) is a prospective, observational cohort designed to assess the long-term safety of biologic and conventional systemic therapies used for adults with moderate-to-severe psoriasis in the U.K. and Republic of Ireland. OBJECTIVES: To describe the demographics, disease severity and comorbidities of patients with psoriasis on enrolment into BADBIR, and to highlight differences in those commencing biologics compared with those on conventional systemic therapies. METHODS: Baseline data were collected from 151 dermatology departments in the U.K. and Republic of Ireland. Descriptive analysis was conducted. RESULTS: As of August 2014, 8399 patients were registered with BADBIR; 5065 (60%) received biologics, of whom 52·8% received adalimumab, 24·6% etanercept, 18·7% ustekinumab and 3·9% infliximab. In the comparator cohort 44·1% received methotrexate, 23·1% ciclosporin, 18·0% acitretin and 7·6% fumaric acid esters. Overall 4897 (58%) were male. Patients on biologics had a higher mean ± SD age and disease duration than patients on conventional systemic therapies (46·3 ± 12·7 vs. 44·3 ± 14·3 years and 23·0 ± 12·6 vs. 19·0 ± 13·4 years, respectively; both P < 0·001). Mean body mass index, Psoriasis Area and Severity Index and Dermatology Life Quality Index scores for patients on biologics were higher than for those on conventional systemic therapies (31·0 ± 7·2 vs. 30·1 ± 7·3 kg m(-2) ; 16·4 ± 8·3 vs. 15·5 ± 7·9 and 17·4 ± 7·5 vs. 15·0 ± 7·1, respectively; all P < 0·001). In total 71% of all patients had comorbidities and 47% had more than one comorbidity. The most frequent comorbidities were obesity (42·1%), hypertension (25·7%), depression (22·1%) and psoriatic arthritis (17·1%). CONCLUSIONS: BADBIR is an invaluable resource to study the safety and effectiveness of both biologic and conventional systemic therapies. Understanding differences in baseline characteristics between cohorts is crucial in undertaking future pharmacovigilance studies.
