Optimising psoriasis care pathway
Optimising the psoriasis care pathway is a multifaceted process that requires input from all healthcare professionals involved in psoriasis patient care. At the primary healthcare level GPs should be more aware of the impact of psoriasis on patients’ lives and use a validated
quality of life instrument to measure this impact and ideally to improve the triage of psoriasis referrals to secondary care. One of the studies presented in this thesis shows a potential benefit of utilizing the Dermatology Life Quality Index (DLQI) as a triage tool to identify those
individuals experiencing the greatest impact on their quality of life. Systemic therapies for psoriasis should be selected on a case by case basis according to guidelines, patients’ comorbidities and their personal preferences. It is important that patients are fully aware of the available evidence to enable them to make informed decisions. Fumarates are one of the recognised systemic therapies for psoriasis. The Cochrane systemic review presented
in this thesis demonstrates its superiority over placebo and possibly similar efficacy to methotrexate; however these findings were based on low-quality evidence. Following the Cochrane review publication, dimethylfumarate was licensed by the European Medicines Agency (EMA) based on new trial evidence and approved by the National Institute for Health and Care Excellence (NICE) as a third line systemic therapy for moderate-to-severe psoriasis. There is growing evidence that continued improvement on fumarates occurs after the usual 12 – 16 week endpoints commonly used in psoriasis trials. Therefore, long-term
randomised clinical trials are needed to measure their true effect and safety in direct headto- head comparisons with other systemic treatments. Inclusion of fumarates in
pharmacovigilance databases will be important to assess rare, delayed adverse effects such as progressive multifocal leukoencephalopathy
Dermatology life quality index (DLQI) as a psoriasis referral triage tool
Most primary care psoriasis referrals in the UK are triaged as ‘routine’, in part because of the prioritisation of skin cancer. As a result, patients with severe psoriasis may wait several months to be seen, enduring quality of life (QoL) impairment that could have been reduced. Furthermore some patients may spontaneously improve by the time they are seen by a specialist, making the appointment unnecessary at that time. Therefore, following approval from the local ethics committee, we conducted a prospective study to evaluate the usefulness of Dermatology Life Quality Index (DLQI) scores in triaging patients with psoriasis referred to our dermatology secondary health care services
Photoletter to the editor: A new variant of ichthyosis follicularis with alopecia and photophobia (IFAP) syndrome with coexisting psoriasiform lesions and palmoplantar keratoderma. IFAP-PPK syndrome?
IFAP is an acronym for a rare congenital ectodermal disorder characterized by ichthyosis follicularis, alopecia and photophobia. A recessive X-linked mode of inheritance was initially proposed but recent reports in girls suggested genetic heterogeneity of this syndrome. We herein describe a 1-year-old boy with clinical features typical of IFAP syndrome plus psoriasis-like lesions and palmoplantar keratoderma (PPK)

Risk of tuberculosis with the use of anti-TNF medications in psoriasis: incidence, screening and management
Tumor necrosis factor (TNF) plays an important role in containing mycobacterial infections. With the rapidly increasing role of TNF inhibitors in dermatology, tuberculosis (TB) is becoming an important and worrisome concern to dermatologists. This paper aims to provide a comprehensive review on the incidence of TB in patients treated with anti-TNF, the variety of TB screening methods, and management of these cases. Various national recommendations have been highlighted. The monoclonal antibodies, infliximab and adalimumab, appear to be more associated with the risk of TB reactivation than the soluble receptor etanercept. Tuberculosis associated with TNF inhibitors, in contrast to classical TB, is more likely to be disseminated, atypical, extra pulmonary, and life threatening. Vigilance for typical and atypical presentations of active TB is mandatory until the end of therapy. Although tuberculin standard test (TST) has been the gold standard for screening of latent TB infection (LTBI) for close to a century, it has several inadequacies and may be unreliable in patients with widespread psoriasis. Interferon gamma release assays (IGRAs) with better diagnostic specificity and sensitivity are a promising adjunct to diagnose LTBI at present. Although appropriate screening and treatment of LTBI will lower the risk of reactivation to a great extent, no chemoprophylactic regimen is fully protective

Assessing the impact of oral isotretinoin on the menstrual cycle: A prospective study on predictors of menstrual irregularities
Background and Objectives: This study aims to evaluate the association between the use of oral isotretinoin and menstrual irregularities in acne patients with previously regular menstrual cycles. Materials and Methods: A prospective observational study was conducted on 58,599 female patients aged 14 to 36 at King Abdullah University Hospital in Irbid, Jordan. The patients were followed for a period of 4.5 to 8 months during treatment and for 2 months post-treatment. Menstrual cycle changes were documented, and statistical analysis was performed to identify any significant associations. Results: A total of 111 (37.1%) patients, who were previously known to have regular menstrual cycles, complained of menstrual changes while using oral isotretinoin. Ninety-nine of those patients who complained of menstrual changes had their cycles back to normal post-treatment. There is a significant difference in the total accumulative dose between those with changes in menses and those without; p-value [0.008]. The most common change that occurred was amenorrhea (p < 0.001), followed by oligomenorrhea and menorrhagia (p < 0.001 and p = 0.050, respectively). The duration of treatment was a significant predictor of menstrual irregularities, with an odds ratio (OR) of 5.106 (95% CI: 1.371–19.020, p = 0.015), indicating a higher likelihood of menstrual changes with increased treatment duration. The total accumulative dose was also significantly associated with menstrual irregularities (OR = 0.964; 95% CI: 0.939–0.990; p = 0.006). Additionally, a family history of PCOS significantly increased the odds of menstrual irregularities (OR = 3.783; 95% CI: 1.314–10.892; p = 0.014). Conclusions: The study identified that 37.1% of the participants experienced changes in their menstrual cycles while undergoing isotretinoin therapy, with the vast majority (89.2%) returning to normal within two months post-treatment. Our logistic regression analysis pinpointed the duration of isotretinoin treatment, the total accumulative dose, and a family history of PCOS as significant predictors of menstrual irregularities
Oral fumaric acid esters for psoriasis
Background: Psoriasis is a chronic inflammatory skin condition that can markedly reduce life quality. Several systemic therapies exist for moderate to severe psoriasis, including oral fumaric acid esters (FAE). These contain dimethyl fumarate (DMF), the main active ingredient, and monoethyl fumarate. FAE are licensed for psoriasis in Germany but used off-licence in many countries.
Objectives: To assess the effects and safety of oral fumaric acid esters for psoriasis.
Search methods: We searched the following databases up to 7 May 2015: the Cochrane Skin Group Specialised Register, CENTRAL in the Cochrane Library (Issue 4, 2015), MEDLINE (from 1946), EMBASE (from 1974), and LILACS (from 1982). We searched five trials registers and checked the reference lists of included and excluded studies for further references to relevant randomised controlled trials. We handsearched six conference proceedings that were not already included in the Cochrane Skin Group Specialised Register.
Selection criteria: Randomised controlled trials (RCTs) of FAE, including DMF monotherapy, in individuals of any age and sex with a clinical diagnosis of psoriasis.
Data collection and analysis: Two review authors independently assessed trial quality and extracted data. Primary outcomes were improvement in Psoriasis Area and Severity Index (PASI) score and the proportion of participants discontinuing treatment due to adverse effects.
Main results: We included 6 studies (2 full reports, 2 abstracts, 1 brief communication, and 1 letter), with a total of 544 participants. Risk of bias was unclear in several studies because of insufficient reporting. Five studies compared FAE with placebo, and one study compared FAE with methotrexate. All studies reported data at 12 to 16 weeks, and we identified no longer-term studies. When FAE were compared with placebo, we could not perform meta-analysis for the primary outcome of PASI score because the three studies that assessed this outcome reported the data differently, although all studies reported a significant reduction in PASI scores with FAE. Only 1 small study designed for psoriatic arthritis reported on the other primary outcome of participants discontinuing treatment due to adverse effects (2 of 13 participants on FAE compared with none of the 14 participants on placebo; risk ratio (RR) 5.36, 95% confidence interval (CI) 0.28 to 102.1; 27 participants; very low-quality evidence). However, these findings are uncertain due to indirectness and a very wide confidence interval. Two studies, containing 247 participants and both only reported as abstracts, allowed meta-analysis for PASI 50, which showed superiority of FAE over placebo (RR 4.55, 95% CI 2.80 to 7.40; low-quality evidence), with a combined PASI 50 of 64% in those given FAE compared with a PASI 50 of 14% for those on placebo, representing a number needed to treat to benefit of 2. The same studies reported more participants achieving PASI 75 with FAE, but we did not pool the data because of significant heterogeneity; none of the studies measured PASI 90. One study reported significant improvement in participants' quality of life (QoL) with FAE, measured with Skindex-29. However, we could not compute the mean difference because of insufficient reporting in the abstract. More participants experienced adverse effects, mainly gastrointestinal disturbance and flushing, on FAE (RR 4.72, 95% CI 2.45 to 9.08; 1 study, 99 participants; moderate-quality evidence), affecting 76% of participants given FAE and 16% of the placebo group (representing a number needed to treat to harm of 2). The other studies reported similar findings or did not report adverse effects fully.
One study of 54 participants compared methotrexate (MTX) with FAE. PASI score at follow-up showed superiority of MTX (mean Difference (MD) 3.80, 95% CI 0.68 to 6.92; 51 participants; very low-quality evidence), but the difference was not significant after adjustment for baseline disease severity. The difference between groups for the proportion of participants who discontinued treatment due to adverse effects was uncertain because of imprecision (RR 0.19, 95% CI 0.02 to 1.53; 1 study, 51 participants; very low-quality evidence). Overall, the number of participants experiencing common nuisance adverse effects was not significantly different between the 2 groups, with 89% of the FAE group affected compared with 100% of the MTX group (RR 0.89, 95% CI 0.77 to 1.03; 54 participants; very low-quality evidence). Flushing was more frequent in those on FAE, with 13 out of 27 participants affected compared with 2 out of 27 given MTX. There was no significant difference in the number of participants who attained PASI 50, 75, and 90 in the 2 groups (very low-quality evidence) whereas this study did not measure the effect of treatments on QoL. The included studies reported no serious adverse effects of FAE and were too small and of limited duration to provide evidence about rare or delayed effects.
Authors' conclusions: Evidence suggests that FAE are superior to placebo and possibly similar in efficacy to MTX for psoriasis; however, the evidence provided in this review was limited, and it must be noted that four out of six included studies were abstracts or brief reports, restricting study reporting. FAE are associated with nuisance adverse effects, including flushing and gastrointestinal disturbance, but short-term studies reported no serious adverse effects
