Correlation of Specific Inflammatory Markers With the Occurrence of Depression in Patients With Psoriasis and Their Use as Biomarkers for the Diagnosis of Depression.

INTRODUCTION: Psoriasis is a systemic disease of the skin and nails associated with a wide range of comorbidities such as depression, psoriatic arthritis and metabolic syndrome. OBJECTIVES: The study aimed to examine a potential association between inflammatory markers (C- reactive protein [CRP] and erythrocyte sedimentation rate [ESR]) and depression in patients with psoriasis. METHODS: A total of 80 individuals were enrolled in the study. Case participants included 28 patients diagnosed with Psoriasis (Beck Depression Inventory-II: :0-13) and 24 patients diagnosed with Psoriasis and Depression (Beck Depression Inventory-II:14-63). Twenty-eight (28) healthy participants comprised the control group.Psoriasis severity was evaluated by using Psoriasis Area and Severity Index, Physician Global Assessment, Body Surface Area and Dermatology Life Quality Index. Written approval was obtained for its use in this study: Cardiff University (09/2015). Other factors considered in the study were obesity using the Body Mass Index, the levels of stress using the Beck Anxiety Inventory, and the presence of insomnia using the Athens Insomnia Scale. Blood draws and inflammatory markers measurements were performed for all participants. RESULTS: Both CRP and ESR levels were higher in the case group (ie Psoriasis and Depression and Psoriasis) compared to healthy controls. Furthermore, psoriatic patients with depression showed increased CRP and ESR levels compared to those of psoriatic patients without depression. CONCLUSIONS: The evaluation of both CRP and ESR and their use to detect the presence of depression in patients with psoriasis can be an important tool for their holistic treatment of theirs.

Real-world treatment patterns, patient-reported outcomes, and effectiveness of flexibledosing etanercept in patients with plaque psoriasis in Greece.

Etanercept is approved for continuous or intermittent use and flexible dosing in plaque psoriasis (PsO). The objectives of this study were to investigate real-world treatment patterns with etanercept in Greek adults with moderate-to-severe PsO. This non-interventional multicenter study included a retrospective-to-prospective (RP) cohort, previously treated with etanercept for ≥24 months and followed for an additional 6 months, and a biologic-naïve, prospective-only (PO) cohort, followed for 6 months after treatment initiation. Parameters assessed included Psoriasis Area and Severity Index (PASI), percentage of body surface area (BSA) affected, Dermatology Life Quality Index (DLQI), and adverse events (AEs). This study enrolled 123 patients (RP, n = 56; PO, n = 67), who mostly adhered to continuous treatment (RP, 68%; PO, 95%). The two cohorts had similar mean baseline-to-endpoint decreases in PASI (-9.5 vs -10.1) and BSA (-11.9 vs -12.3). The PO-CTP population had a mean DLQI baseline-to-endpoint score decrease of -5.8, which was statistically significant and clinically meaningful. Treatment-emergent AE rates were 58.9% (RP) versus 26.9% (PO). These real-world data suggest a similar effectiveness of continuous and intermittent etanercept treatment in Greek patients with PsO.

Efficacy of adalimumab in moderate to severe hidradenitis suppurativa: Real life data.

Hidradenitis suppurativa (HS) is a relapsing, inflammatory disease characterized by painful nodules, abscesses, sinuses track formation and scarring. HS has a great impact on patients' quality of life and its treatment may be really challenging. Adalimumab provides a new therapeutic option for HS. Our aim was to assess the therapeutic potential of adalimumab on patients with HS based on the data from the daily clinical practice of an HS Outpatient Clinic. 19 patients with clinically evident moderate to severe HS, under adalimumab treatment for at least 24 week, participated in this observational, retrospective study. The Hidradenitis Suppurativa Physician's Global Assessment scale, Modified Santorius scale and Dermatology Life Quality Index (DLQI) at baseline, week 4, week 12 and week 24 were retrieved from the records. Both Modified Santorius score and DLQI were significantly decreased during the weeks of evaluation (Friedman's test; P < 0.001). The proportion of patients who achieved clinical response was 10.5% (n = 2) at week 4, 42.1% (n = 8) at week 12 and 63.2% (n = 12) at week 24. Treatment with adalimumab was linked with both clinical remission of HS and improvement of patients' quality of life.

An extension of a multicenter, randomized, split-face clinical trial evaluating the efficacy and safety of chromophore gel-assisted blue light phototherapy for the treatment of acne.

A variety of laser/light-based devices have been reported to be effective for the treatment of acne, yet no long-term data on efficacy and safety have been published. A first 12-week clinical trial ("Main trial") recently demonstrated that the KLOX BioPhotonic System, an LED blue light device using photo-converter chromophores, can significantly improve moderate and severe facial acne vulgaris with an excellent safety profile. This Extension trial followed the Main trial, using the same BioPhotonic System, with the same dose and instructions for use, on patients having already completed treatment in the Main trial. Main objectives of this open-label long-term extension 12-week study were to evaluate the efficacy of the KLOX BioPhotonic System on the untreated hemiface during the Main trial, as well as the duration of response on the hemiface treated during the first 12-week Main trial. Despite their young age (mean age: 21.6 years) and their 12-week participation in the Main trial, 49 (54.4%) of the total number of patients who participated in the Main trial enrolled in this additional 12-week Extension trial. Baseline grading of acne was performed with the Investigator's Global Assessment (IGA) scale. For each patient, the hemiface randomly selected as a control during the Main trial received 6 weeks of treatment (twice weekly) and was then followed up for an additional 6 weeks. The first hemiface treated in the Main trial was consequently observed throughout the Extension trial, allowing for a further 12-week assessment of outcomes (total 24 weeks). In light of an additional 12 weeks of treatment on the contralateral face, the patient compliance rate was excellent, with 91.9% of the total number of patients receiving at least 80% of the treatments. Patients with a baseline IGA grade of 2 (mild) on the treated hemiface demonstrated a success rate of 58.3 and 66.7% at weeks 6 and 12, respectively. At these same time points, subjects with a baseline IGA grade of 3 (moderate) demonstrated a success rate of 81.8 and 90.0%. Patients with a baseline IGA grade of 4 (severe) demonstrated a success rate of 100% at both week 6 and week 12. When evaluating the originally treated hemifaces from the Main trial, the rate of return to baseline at 24 weeks was calculated to be 15.5%. This latter outcome confirmed the long duration of effect following treatment. The patient safety profile was also excellent, with very few related adverse events. The BioPhotonic System, which is comprised of LED blue light phototherapy and photo-converter chromophores, provides long-term efficacy and safety in the treatment of acne vulgaris, with a rate of compliance above what is generally observed in a young population of patients suffering from acne vulgaris, especially in light of sequential enrollment in a study treating one hemiface.

Serum Leptin, Resistin, and Adiponectin Concentrations in Psoriasis: A Meta-Analysis of Observational Studies.

BACKGROUND: Psoriasis is an immune-mediated, inflammatory disease. Adipokines contribute to the regulation of immune-mediated processes and inflammation. OBJECTIVE: The aim of our study was to systematically review the literature for studies that have evaluated the circulating concentrations of adipokines in patients with psoriasis and controls and to meta-analyze the best evidence available. METHODS: Eligible were studies that have assessed leptin, resistin, or adiponectin concentrations in psoriatic patients and a reference group. The study was conducted in adherence with the PRISMA standards. RESULTS: Psoriatic patients had higher leptin concentrations compared to controls (random effects model, mean difference, MD = 5.64 ng/mL, 95% CI: 3.00-8.29, p < 0.0001). Heterogeneity among studies was high (I2 = 95.9%). Psoriatic patients had higher resistin concentrations compared to controls (MD = 4.66 ng/mL, 95% CI: 2.62-6.69, p < 0.0001). Heterogeneity was high (I2 = 99.2%). Finally, psoriatic patients had lower adiponectin concentrations compared to controls (MD = -1.87 µg/mL, 95% CI: -2.76 to -0.98, p < 0.0001). Heterogeneity was high (I2 = 95.9%). CONCLUSION: The study supported the hypothesis that leptin and resistin concentrations are higher and adiponectin concentrations are lower in patients with psoriasis compared to controls. Hereby, the suggested pathogenic link between psoriasis and metabolic syndrome/obesity is reinforced and the role of comorbidities in psoriasis is highlighted.

Spectrum of Autoimmune Bullous Diseases in Northern Greece. A 4-year Retrospective Study and Review of the Literature.

Bullous Diseases Unit at the 2nd Department of Dermatology and Venereology, Aristotle University of Thessaloniki was founded with the aim to provide the optimal diagnostic approach and treatment of patients with autoimmune bullous diseases (AΙBD). We processed all AIBD files of patients diagnosed from 2011 to 2014 in order to record all epidemiological data and therapeutic manipulations during monitoring. 57 patients were diagnosed with intraepidermal and 62 with subepidermal bullous diseases. There were 51 cases (89%) of pemphigus vulgaris (PV) and 6 (11%) of pemphigus foliaceus (PF), whereas 45 (73%) patients were diagnosed with bullous pemphigoid (BP), 9 (14%) with mucous membrane pemphigoid (MMP), 3 (5%) with pemphigoid gestationis (PG), 3 (5%) with linear IgA dermatosis (LAD), 1 (2%) with epidermolysis bullosa aquisita (EBA), and 1 patient with an undefined subepidermal AIBD. The mean age of patients within the pemphigus spectrum was 57 years. In the pemphigoid spectrum, the mean age was 72 years. Comorbidities were reported with increasing frequency, as well as treatment options other than systemic corticosteroids, such as adjuvant immunosuppressive agents, which were used to achieve complete remission. This is a report from a tertiary AIBD Referral Center in northern Greece. Our data from a 4-year period contribute to the completion of the global geographic incidence map of AIBD.

Prevalence of onychomycosis among patients with nail psoriasis who are not receiving immunosuppressive agents: Results of a pilot study.

Nail psoriasis and onychomycosis can often be hard to differentiate clinically and may coexist, complicating each other's course. The aim of this study was to determine the prevalence of onychomycosis among patients with nail psoriasis not being treated with immunosuppressive agents, which constitute an independent risk factor for fungal infections. A cross-sectional study was performed. All adult patients with nail psoriasis who were not receiving antifungal and/or immunosuppressive treatment were recruited at the 2nd University Dermatology Department of Aristotle University of Thessaloniki from 10/2016 till 02/2017. If onychomycosis was clinically suspected, nail samples were collected and direct microscopy with 15% KOH solution and culture were performed. Target-NAPSI and DLQI score were also calculated. Of the 23 patients recruited, 20 were men and 3 were women, with a mean age of 53.43 years (48.25, 58.62), a mean target-NAPSI score of 10.72 (9.62, 11.77) and a mean DLQI score of 10.17 (7.46, 12.89). A total of 34.78% of patients tested positive for onychomycosis. Yeast were isolated in 37.50% of cases, non-dermatophyte filamentous fungi in 37.50% and T. rubrum in 12.50%. The prevalence of onychomycosis among nail psoriasis patients is higher than that among the general population of Greece (15%-20%). Yeast and moulds predominate in infection cases of nail psoriasis patients.

Netherton Syndrome: A Genotype-Phenotype Review.

Netherton syndrome (OMIM #256500) is a rare but severe autosomal recessive form of ichthyosis that affects the skin, hair, and immune system. The identification of SPINK5, which encodes for the serine protease inhibitor LEKTI, as the gene responsible for Netherton syndrome, enabled the search for causative mutations in Netherton syndrome patients and families. However, information regarding these mutations and their association with the pathological Netherton syndrome phenotype is scarce. Herein, we provide an up-to-date overview of 80 different mutations in exonic as well as intronic regions that have been currently identified in 172 homozygous or compound heterozygous patients from 144 families. Genotypes with mutations located more upstream in LEKTI correlate with more severe phenotypes compared with similar mutations located towards the 3' region. Furthermore, splicing mutations and post-transcriptional mechanism of nonsense-mediated mRNA decay affect LEKTI expression in variable ways. Genotype-phenotype correlations form the basis of prenatal diagnosis in families with a history of Netherton syndrome and when consanguinity is implied.

Sclerotic Regressing Large Congenital Nevus.

Regression of congenital nevi is usually associated with loss of pigment or halo formation. In rare cases, regression is characterized by sclerosis and hair loss. We describe a rare case of a sclerotic hypopigmented large congenital melanocytic nevus in which a localized scleroderma-like reaction process of regression seemed to have started in utero and progressed throughout early childhood.

A multicenter, randomized, split-face clinical trial evaluating the efficacy and safety of chromophore gel-assisted blue light phototherapy for the treatment of acne.

BACKGROUND: Although a variety of laser/light-based devices have been reported to be effective for the treatment of acne, long-term data on efficacy and safety in the management of moderate and severe inflammatory acne is lacking. The objective of this 12-week clinical trial was to evaluate the efficacy and safety of the KLOX BioPhotonic System, a LED blue light device using specific photo-converter chromophores, in the treatment of moderate to severe acne vulgaris. METHODS: One patient hemiface was randomly selected to receive 6 weeks of treatment (twice weekly) with the LED light and the photo-converter chromophores whereas the contralateral hemiface was not treated with the BioPhotonic System. All patients were provided with a skin cleanser and a non-comedogenic cream with ultraviolet protection to be used on the entire face during the treatment period. Following completion of the 6-week treatment period, the patient was followed for an additional 6 weeks. Efficacy was assessed through changes in acne severity using the Investigator's Global Assessment (IGA) scale and inflammatory acne lesion counts, both evaluated against baseline at weeks 6 and 12. Safety was assessed through physical exam, vital signs, laboratory evaluations, and physician and patient reporting of adverse events. RESULTS: A reduction of at least two grades in IGA scale severity was demonstrated in 51.7% of patients at week 12. Furthermore, at week 12, subjects with a baseline IGA grade of 3 (moderate) demonstrated a success rate (2 or greater grade drop) of 45.3% whereas patients with a baseline IGA grade of 4 (severe) demonstrated a success rate of 61.1%. Acne inflammatory lesion counts confirmed these results, with a reduction of at least 40% of lesions in 81.6% of treated hemifaces after 12 weeks. Treatment was considered as safe and well tolerated, with no serious adverse event and no patient discontinuation from the study from any adverse event. Patients' quality of life was also improved with a decrease of pain linked to acne after the 6-week treatment period. CONCLUSIONS: The BioPhotonic System comprised of LED blue-light phototherapy and photo-converter chromophores was found to be efficacious and safe, with a sustained clinical response at 12 weeks for the management of moderate to severe facial inflammatory acne.

The cellular microenvironment and neoplastic population in mycosis fungoides skin lesions: a clinicopathological correlation.

The cellular microenvironment has been proven to play a crucial role in solid tumours and seems to be important in haematologic malignancies, however, it has not been adequately investigated in primary cutaneous T cell lymphomas. The aim of this study was to register the composition of the cellular microenvironment in mycosis fungoides skin lesions and correlate the composing parameters with the clinical data and follow-up results. The presence of eosinophilic polymorphonuclear leukocytes, B lymphocytes, CD68+ macrophages, and CD1a+ epidermal Langerhans and antigen-presenting dermal dendritic cells, as well as their relation to clinicopathological parameters, were studied in 16 mycosis fungoides cases of different disease stages. The presence and nature of the participating T cell populations was also investigated. CD8+ tumour infiltrating T cells and CD56+ cells were found among neoplastic CD4+ T cells in the lesions. Generally, eosinophils and B lymphocytes were absent or in low numbers, regardless of clinical presentation, contrary to tumourous lesions. Macrophages and CD1a+ cells were constantly present, even in early-stage mycosis fungoides. The reduced presence of the CD1a+ population was associated with resistance to therapy (x2; p = 0.012). There is a striking difference in cellular microenvironment composition between early and advanced mycosis fungoides lesions.

Bilateral Aleukemic Myeloid Sarcoma of the Eyelids With Indolent Course.

Leukemic infiltrates may be seen in the skin in the absence of detectable bone marrow involvement. Leukemia cutis may exceptionally occupy the eyelids. An unusual case of a 58-year-old man presenting bilateral erythematous eyelid lesions, proven to be aleukemic leukemia cutis, is reported. Biopsy was conducted and hematoxylin/eosin stained sections were histologically evaluated. Immunohistochemistry was also performed.Light microscopy revealed cutaneous infiltration by a neoplastic population consisting of medium-sized cells. These cells infiltrated the overlying epidermis leading to focal microulcerations. The morphological and immunohistochemical characteristics of the neoplastic population were compatible with myeloid leukemia cutis. The bone marrow biopsy was normocellular for the patient's age. Although chemotherapy was advised, the patient refused any treatment. He remains free of leukemia or evolution of eyelid lesions approximately 1 year after diagnosis. Leukemia cutis of the eyelids is a rare manifestation of acute leukemia and may remain aleukemic in adults for an indefinite period of time.
