Objective Real-world evidence of the long-term effectiveness of TNF-α inhibitor (TNFi) therapy in patients with PsA is limited. This study was conducted to describe patterns of TNFi therapy and treatment responses in patients with PsA treated in UK clinical practice. Methods A multicentre, retrospective, observational cohort study of consenting patients treated with TNFi for PsA with ≥3 years follow-up from first TNFi initiation (observation period) was carried out in 11 UK National Health Service hospitals. Data were collected concerning baseline patient characteristics, PsA-related treatment pathways and TNFi treatment responses (PsA response criteria components: swollen/tender joint counts, physician and patient global assessments). Results The mean age of patients ( n = 141) was 50.3 ( s . d .: 12.1) years (50% male). During a median observation period of 4.5 (range: 3.4–5.5) years, patients received a median of one (range: one to five) TNFi. Twelve-week response rates for first TNFi (where available) were as follows: 80% ( n = 64/80) for swollen joint counts, 79% ( n = 63/79) for tender joint counts, 79% ( n = 37/47) for physician global assessments, 69% ( n = 41/59) for patient global assessments and 79% ( n = 37/47) for PsA response criteria. At the end of the observation period, the proportions of patients remaining on first, second, third and fourth/fifth TNFi were 56, 15, 5 and 3%, respectively; 21% of patients permanently discontinued TNFi therapy. Conclusion Long-term TNFi therapy is generally well tolerated and may be effective; however, after initial TNFi failure, there appears to be progressively less benefit and more adverse effects with successive TNFi switches. Strategies are needed for effective therapy for PsA beyond the first TNFi failure.

Biologics are novel and important agents in the treatment of severe psoriasis. These agents block specific molecular steps in the inflammatory cascade, thereby reducing activation and proliferation of keratinocytes. Prescreening for biologic agents and careful monitoring of patients is important. There are four biologics currently licensed and used in the treatment of psoriasis in the European Union. This is an evidence-based review examining clinical trials and focusing on the long-term safety data for four biologic agents. Current British Association of Dermatology guidance for the use of biologics in psoriasis and guidelines on the management of psoriasis from the National Institute for Health and Clinical Excellence have been used. Advances on safety information since 2009 in clinical trials are reviewed. The results show that overall there is no statistical significance in the incidence of adverse effects of biologics versus placebo. However, there are serious adverse effects that are reported for biologics that need to be assessed for and addressed promptly. Results of studies discussing major adverse cardiovascular events are also reviewed.

Objectives: Congenital adrenal hyperplasia (CAH) is a group of rare autosomal-recessive disorders that arise from genetic deficiencies in key enzymes involved in cortisol synthesis. The burden of CAH has never been comprehensively reviewed; this literature review was conducted to summarise the existing burden of illness evidence available for these patients. Methods: A structured, comprehensive literature review was conducted to identify articles describing the burden and treatment landscape of CAH. Literature databases (MEDLINE, Embase, the Cochrane Library and EconLit), websites and conference proceedings were searched. Searches were performed in 2016 and updated in June 2020; eligible articles presented evidence for patients with CAH or paediatric patients with adrenal insufficiency (AI), for ≥1 topic of interest (epidemiology; natural history; clinical characteristics; humanistic, caregiver and economic burden; treatment options; or clinical guidelines). The evidence presented here focusses on the humanistic and economic burden of CAH in adults. Results: A total of 3,711 citations were identified and 336 were included; 84 references reported humanistic or economic burden data relevant to adult patients with CAH. 51 publications were identified reporting patient symptoms, comorbidities and cardiometabolic risk factors; 38 reporting on the impact of CAH on health-related quality of life (HRQL); 5 reporting patient views and 2 reporting economic burden associated with CAH. Compared to the general population, adult patients with CAH were found to be significantly shorter, have poorer bone health, increased levels of obesity, impaired male and female fertility, higher blood pressure and cholesterol levels, have more psychiatric and neurological disorders and have poorer cognitive performance. Adult patients with CAH were also found to have greater insulin resistance and higher levels of type 2 diabetes (T2D). CAH patients are also at risk of adrenal crisis, which contributes to excess mortality. The reported HRQL in adults with CAH varies, with increased impairment observed in more severe forms of CAH, and challenges due to living with a chronic disease impacting HRQL varying according to sex. “Sick day rules” where patients need to double or triple treatment doses, have a significant impact on patients’ HRQL and also have an impact on patients’ resource use, with a UK study reporting that CAH patients will implement these rules 171 times over their lifetime, and be hospitalised for adrenal crises on 11 occasions. CAH was also found to have a significant economic impact, with significantly higher annual healthcare costs compared to matched controls (p=0.007 for patients aged 18–40 years; p<0.001 for patients aged ≥40 years). Conclusions: This comprehensive review highlights that CAH in adults is associated with a significant humanistic and economic burden.
