A randomised half body prospective study of low and medium dose regimens using the 308 nm excimer laser in the treatment of localised psoriasis
This study compared two dose-escalation regimens using the 308 nm excimer laser treating localised plaque psoriasis, to determine the optimal regimen. A randomised, left–right body trial was designed including patients aged >18 years with localised plaque psoriasis (<10% body surface area). The standard/low dose regimen started at 70% of the minimal erythema dose (MED), with 20% dose increments. The medium dose regimen commenced at 200% MED, with 25% increments. Patients were treated until disease clearance or a maximum of 36 treatments. Fifteen patients aged 28–55 years completed the study. Psoriasis severity index scores analysed at weeks 0, 6 and 12 showed a significant reduction with each regimen (p < 0.0001). Six patients cleared, seven had significant improvement with uneven clearance of plaques and two failed. Average remission was four months (range 1–12 months). There was a significant reduction in DLQI (p = 0.014). Excimer laser improved psoriasis and reduced DLQI scores, but clearance was incomplete for many patients and remission was short-lived. Adverse effects of pain and blistering were commoner with the medium dose regimen, without any benefit in psoriasis clearance
The use of transient elastography and fibrotest for monitoring hepatotoxicity in patients receiving methotrexate for psoriasis
IMPORTANCE There is a need for noninvasive tools to monitor hepatotoxicity in patients with psoriasis who are receiving methotrexate sodium.
OBJECTIVE To evaluate the use of transient elastography (TE) and FibroTest (FibroSURE in the United States), an indirect serum marker of fibrosis, in this population.
DESIGN, SETTING, AND PARTICIPANTS Patients receiving methotrexate therapy for psoriasis between January 2008 and September 2009 were recruited from a dermatology outpatient department. Transient elastography and FibroTest were performed, and patients with abnormal results were considered for liver biopsy. Serial procollagen III peptide (PIIINP) results were recorded.
INTERVENTIONS Transient elastography uses pulse-echo ultrasonography to measure liver stiffness, and this result is an indirect measure of hepatic fibrosis. FibroTest is an indirect serum marker of hepatic fibrosis.
MAIN OUTCOMES AND MEASURES Procollagen III peptide, TE, and FibroTest results, as well as the need for liver biopsy in this cohort.
RESULTS Seventy-seven patients (41 male [ 53%]) were included. Fifty (65%) patients had a valid TE assessment, and 9 (18%) had an abnormal result (range, 7.1-11.3 kPa). Being overweight or obese increased the possibility of obtaining an invalid TE result significantly (P = .01). On univariate analysis body mass index (r = 0.40, P = .005) and age (r = 0.52, P = .005) were correlated with abnormal TE results. Seventy-one patients received a FibroTest and 11 of 70 analyzed (16%) had an abnormal result (METAVIR score &gt;F1). Age (r = 0.31, P = .009), cumulativemethotrexate dose (r = 0.31, P =.01), and duration of methotrexate therapy (r = 0.36, P = .002) were correlated with abnormal FibroTest results. There was no correlation between PIIINP levels and TE results or between PIIINP levels and FibroTest results. Steatosis was demonstrated in all 5 patients who received liver biopsies during the study. Two patients had hepatic fibrosis, with 1 showing a sinusoidal pattern of fibrosis attributed to steatohepatitis.
CONCLUSIONS AND RELEVANCE Transient elastography and FibroTest are effective noninvasive tools for monitoring hepatotoxicity in patients receiving methotrexate for psoriasis. We propose that the need for liver biopsy could be reduced if abnormalities in at least 2 tests (serial PIIINP, TE, or FibroTest) are required before biopsy is considered. This strategy should be evaluated in prospective studies

Clinicopathological characteristics of individuals with co-existing melanoma and chronic lymphocytic leukaemia:a multicentre cohort study
BACKGROUND: Individuals with a prior diagnosis of chronic lymphocytic leukaemia (CLL) have a higher risk of developing melanoma and exhibit poorer outcomes than patients without CLL. However, there are limited data reporting the clinicopathological features of melanoma diagnosed in patients with CLL. AIMS: To review clinicopathological characteristics of patients with coexisting diagnoses of melanoma and CLL. METHODS: A retrospective review was undertaken for patients with coexisting diagnoses of melanoma and CLL between 2005 and 2015 in 11 centres in the UK and Ireland. RESULTS: Overall, 46 cutaneous melanomas identified in 45 patients were included. In 28 (62.2%) patients, melanoma was diagnosed after an existing diagnosis of CLL. In this group, mean Breslow thickness was 2.7 mm (range 0.2-25 mm). Ten patients (35.7%) developed locoregional recurrence and 8 (28.6%) developed distant metastases. Melanoma-specific mortality was 5 of 28 (17.9%) and all-cause mortality was 13 of 28 (46.4%). In 17 patients, melanoma was diagnosed before CLL. In this group, mean BT was 2.9 mm (range 0.4-14 mm); five patients (29.4%) developed locoregional recurrence and three (17.6%) developed distant metastases. Melanoma-specific mortality was 1 of 17 (5.8%) and all-cause mortality was 5 of 17 (29.4%) in this group. CONCLUSIONS: To our knowledge, this is the first and largest cohort study to report clinicopathological data of coexisting melanoma and CLL in the UK and Ireland. Although the thickness of primary melanoma was not different before or after a CLL diagnosis, melanoma recurrence and melanoma-specific mortality appear to be more common in patients with a prior diagnosis of CLL.RD&E staff can access the full-text of this article by clicking on the 'Additional Link' above and logging in with NHS OpenAthens if prompted.Published version, accepted version (12 month embargo), submitted versio
The sero-epidemiology of human papillomavirus among Caucasian transplant recipients in the UK
<p>Abstract</p> <p>Background</p> <p>Despite intensive study of high-risk mucosal human papillomaviruses (HPV), little is known of the epidemiology of cutaneous HPV. As part of a study of cutaneous squamous cell carcinoma and HPV among organ transplant recipients (OTR) from London and Oxford, we investigated the seroprevalence and risk factors for 34 HPV types (detected using Luminex technology) among 425 Caucasian OTR without skin cancer.</p> <p>Results</p> <p>Overall, 86% of participants were seropositive to at least one HPV: 41% to mucosal alpha types, 33% to cutaneous alpha types, 57% to alpha types, 56% to beta, 47% to gamma types and 45% to other types (nu, mu, HPV101 and 103). In both centres, the most common types were HPV6 (33% and 26% for London and Oxford respectively), HPV8 (24% and 18%), HPV15 (26% and 29%), HPV17 (25% and 21%), HPV38 (23% and 21%), HPV49 (19% and 21%), HPV4 (27% and 23%), HPV65 (30% and 25%), HPV95 (22% and 20%), HPV1 (33% and 24%) and HPV63 (28% and 17%). The seroprevalence of 8 HPV types differed significantly (P < 0.05) between London and Oxford. Those individuals seropositive to multiple types of one genus were more likely to be seroreactive to multiple types of another genus. As expected, antibodies against mucosal alphaHPV types were more frequent in younger patients and among women. Sunbed use and sunbathing was associated with seropositivity to multiple gammaHPV (P-trend = 0.007) and self-history of abnormal smear was related to seroactivity to multiple betaHPV (P = 0.01). Skin type and other self reported markers of exposure to ultraviolet radiation were not consistently associated with any HPV types. No other distinguishing epidemiological features of transplant recipients with antibodies against single or multiple HPV types were identified.</p> <p>Conclusion</p> <p>Findings for mucosal HPV types were in line with results from previous studies. We observed differences in HPV seroprevalence between organ transplant recipients from two geographically close centres but no clear risk factor was found associated with cutaneous HPV seropositivity among organ transplant recipients. These findings have implications for interpretation of future seroepidemiology studies addressing the association between HPV and cutaneous SCC in OTR populations.</p
