RESUMO
BACKGROUND: The etiology of vitiligo has not been completely elucidated. Recently, 25-hydroxyvitamin D (25(OH)D) and IL-33 levels were found to be associated with the development of the vitiligo. The aim was to assess relationship between 25(OH)D, IL-33 levels, and clinical improvement after narrow-band UVB treatment in vitiligo. METHOD: Patients with vitiligo who underwent at least 48 sessions of narrow-band UVB treatment were included in this study. Age, gender, smoking status, family history of vitiligo, type of vitiligo, body surface area affected by vitiligo, and vitiligo activity were recorded. 25(OH)D and IL-33 were measured and compared at baseline, second month, and fourth month. RESULTS: Twenty patients with vitiligo and 20 healthy controls were included in this study. The mean baseline 25(OH)D level of vitiligo group was statistically significantly lower than the control group's (p < .05). The mean baseline IL-33 level was higher in vitiligo group with no statistically significantly difference (p > .05). The increase in 25(OH)D level and the decrease in vitiligo-affected body surface area were found to be statistically significant during treatment (p < .05). The mean IL-33 levels were found to be lower at the second and fourth month compared to baseline. However, there were no statistical significance (p > .05). CONCLUSION: Low levels of 25(OH)D are thought to play a role in the etiopathogenesis of vitiligo. 25(OH)D increase due to phototherapy may have a role in repigmentation independently from the direct effect of narrow-band UVB.

BACKGROUND: Pruritus, which is the most frequent subjective symptom of psoriasis, may cause significant discomfort, embarrassment and even interfere with patients normal daily activities. However, the perception of itch in various psoriasis subtypes remains unknown. OBJECTIVES: The aim of this study was to investigate and to characterize pruritus in different clinical variants of psoriasis. METHODS: This cross-sectional, binational, multicentre study included 295 subjects suffering from nine different clinical subtypes of psoriasis: large-plaque psoriasis (n = 45), nummular psoriasis (n = 32), guttate psoriasis (n = 31), scalp psoriasis (n = 32), inverse psoriasis (n = 23), erythrodermic psoriasis (n = 33), palmoplantar psoriasis vulgaris (n = 33), palmoplantar pustular psoriasis (n = 42) and generalized pustular psoriasis (n = 23). Measures included sociodemographic and anthropometric data, detailed pruritus characteristics including but not limited to pruritus intensity, frequency and extend, as well as psoriasis severity. RESULTS: The lifetime prevalence of pruritus in each clinical variant of psoriasis was similar and quite high, reaching up to 100% in some disease subtypes (i.e., nummular psoriasis, scalp psoriasis and generalized pustular psoriasis). Psoriasis severity correlated with pruritus intensity in scalp psoriasis, palmoplantar pustular psoriasis and generalized pustular psoriasis. The age, duration of psoriasis and BMI did not interfere with the intensity of itch. CONCLUSIONS: Pruritus is highly prevalent in each clinical variant of psoriasis. However, the sensation of itch is very individual, difficult to universally describe even in the same subtype.

Background: Monocyte to high-density lipoprotein cholesterol ratio (MHR) is a novel inflammatory biomarker which has been associated with cardiovascular diseases. Objective: To study MHR in patients with psoriasis treated with biological agents. Methods: Between April 2019 and August 2022, MHR was retrospectively evaluated in patients with psoriasis before and 3 months after treatment with infliximab, adalimumab, etanercept, ixekizumab, secukinumab, and ustekinumab in a university hospital in Ankara, Turkey. Results: This study included 128 patients, 53 females and 75 males. 39 (30.5%) patients were treated with infliximab, 26 (20.3%) with adalimumab, 8 (6.3%) with etanercept, 18 (14.1%) with ixekizumab, 12 (9.4%) with secukinumab, and 25 (19.5%) with ustekinumab. The median MHR was 0.0127 (0.0086-0.0165) in females and 0.0146 (0.0119-0.0200) in males (p = 0.011). The median MHR decreased after treatment with adalimumab, ixekizumab, secukinumab, and ustekinumab, whereas it increased after treatment with infliximab and etanercept (p = 0.790, p = 0.015, p = 0.754, p = 0.221, p = 0.276, p = 0.889, respectively). Conclusion: MHR significantly decreased in patients with psoriasis after treatment with ixekizumab. Since high MHR levels have been associated with poor clinical outcomes in patients with cardiovascular diseases, ixekizumab might have a positive impact in the treatment of psoriasis patients who had cardiovascular diseases. We suggest that MHR may be useful both in establishing appropriate biological agent treatment and in the follow-up of patients with psoriasis treated with biological agents.

Introduction: Psoriasis patients may be susceptible to malignancy due to chronic inflammation. Moreover, biological agents which are used in the treatment of psoriasis might increase the risk of malignancy due to their immunosuppressive effect. Objectives: We evaluated the mammography results of female patients with psoriasis aged over 40 years before the initiation of biological agent treatment. We aimed to determine whether breast cancer screening with mammography should be a prerequisite before the initiation of biological agent treatment for psoriasis. Methods: Between April 2019 and March 2021, medical records of female psoriasis patients aged over 40 years were reviewed retrospectively. Results: This study included 42 female psoriasis patients (mean age: 53.52 ± 7.09). BI-RADS score was 2 in 18 (42.9%) patients, 1 in 13 (31%) patients, 3 in 9 (21.4%) patients and 4A in 1 (2.4%) patient. Isodense masses were detected in 10 (23.8%) patients, while 6 (14.3%) patients had intramammary lymph nodes. Mammography revealed microcalcifications in 6 (14.3%) patients, macrocalcifications in 1 (2.4%) patient and a hamartoma in 1 (2.4%) patient. Isodense masses, calcifications and intramammary lymph nodes were associated with long disease duration (> 10 years). Intramammary lymph nodes were more common in patients treated with biological agents previously compared to biologic-naive patients. Conclusions: We suggest that female patients over 40 years, especially those who had a long disease duration, family history of breast cancer and previous history of treatment with biological agents should undergo mammography before the initiation of biological agents for the treatment of psoriasis.
RESUMO
BACKGROUND: Quality of life (QoL) and sleep, which are essential for well-being in the mental, physical, and socioeconomic domains, are impaired in psoriatic patients. However, the exact role of the clinical subtype of psoriasis in this aspect remains poorly studied. OBJECTIVES: The aim of this study was to investigate differences in QoL impairment and sleeping problems in patients suffering from various clinical subtypes of psoriasis and to evaluate the effects of pruritus on QoL. METHODS: This cross-sectional, multicenter study included 295 eligible subjects with diagnosed psoriasis. Each patient was examined with the use of the same questionnaire. Measures included predominant subtype of psoriasis, disease severity, pruritus scores, patients' health-related QoL and the incidence of sleep disturbance. RESULTS: The QoL of most patients was decreased irrespectively of clinical psoriasis subtype, however, the most impaired QoL was in patients with erythrodermic psoriasis. The majority of patients reported sleep disturbances caused by pruritus, albeit there was no relevant differences between analyzed subgroups in this aspect of patients' well-being. Pruritus was an important factor determining QoL and sleeping problems in the studied population. CONCLUSIONS: Identifying the most disturbing area of life and recognizing the most bothersome subjective symptoms of psoriasis are pivotal to focusing on the most relevant treatment goal and achieving therapeutic success.
RESUMO
Mycosis fungoides (MF) is a skin lymphoma characterised by atypical T lymphocyte infiltration, which may present with patches and tumors in advanced stages. Treatment options in MF aim to reduce symptoms, since patients usually do not achieve complete cure. Bexarotene is used for treatment-resistant early stage MF and advanced stages of the disease. It has been suggested that white blood cell (WBC)/absolute lymphocyte count, WBC, absolute lymphocyte and eosinophil counts might be prognostic factors in MF. Therefore, we investigated the changes in complete blood count (CBC) parameters and CBC-derived inflammatory biomarkers in patients with MF treated with bexarotene. The results revealed that neutrophil (NE)%, NE numbers, neutrophil/lymphocyte, derived neutrophil/lymphocyte, (neutrophil × monocytes)/lymphocyte and (neutrophils × monocytes × platelets)/lymphocyte counts decreased in all patients three months after bexarotene treatment. We suggest that these inflammatory biomarkers can be used in the follow-up of patients with MF receiving bexarotene treatment. Moreover, these results indicate that decrease in these inflammatory biomarkers may signify improvement of the disease. Key Words: Bexarotene, Inflammatory biomarkers, Mycosis fungoides.

INTRODUCTION: Acne vulgaris is a multifactorial disease. One of the main factors that plays a role in acne pathogenesis is an increase in sebum secretion. For sebum secretion, sebocyte differentiation followed by sebogenesis is essential. Sebocyte differentiation and proliferation, and sebum synthesis are controlled by complex pathways. Studies have shown that perilipin 2 and melanocortin 5 receptors play a role in sebogenesis. This study sought to determine whether levels of perilipin 2 and melanocortin 5 receptors have an impact on the development of acne vulgaris. METHODS: A total of 65 patients diagnosed with acne and 43 healthy control subjects were included in the study. Perilipin 2 and melanocortin 5 receptor levels were analyzed using the enzyme-linked immunosorbent assay (ELISA) technique. RESULTS: No significant differences were observed between the acne group and the control group in serum perilipin 2 (p = 0.594) and melanocortin 5 receptor (p = 0.213) levels. In the moderate acne group, perilipin 2 and melanocortin 5 receptor levels were significantly higher than in the mild acne group (p = 0.0014, p = 0.003). The levels in the severe acne group were not higher compared to the moderate and mild acne groups. CONCLUSION: This study failed to detect any association between acne pathogenesis and perilipin 2 and melanocortin 5 receptor serum levels. However, these proteins may have an influence on acne severity.

Psoriasis is a chronic, inflammatory skin disease present in about 3% of the world's population. The clinical symptoms manifest diversely, therefore one can distinguish several subtypes of psoriasis. The majority of patients with psoriasis experience pruritus, which is an unpleasant sensation that decreases patients' quality of life. The knowledge on pruritus in different subtypes of psoriasis is limited. We have performed a cross-sectional, prospective, and multicenter study to evaluate the relationship between clinical subtypes of psoriasis (large-plaque, nummular, guttate, palmoplantar, inverse, erythrodermic, palmoplantar pustular, generalized pustular psoriasis, and psoriasis of the scalp) and the prevalence, intensity, and clinical manifestation of itch. We introduced a questionnaire assessing various aspects of pruritus to a total of 254 patients. Out of these, 42 were excluded. Pruritus was present in 92.9% of the remaining patients and its prevalence did not depend on the clinical subtype. A correlation between the severity of psoriasis and the intensity of itch was explicitly noticeable in palmoplantar pustular psoriasis and scalp psoriasis (p < 0.05). The itch sensation was individual and differed among subtypes of psoriasis. In conclusion, pruritus is a frequent phenomenon, and its presentation is different in various subtypes of psoriasis.
RESUMO
BACKGROUND: Internalized stigma, adoption of negative attitudes and stereotypes of the society regarding persons' illness, has not been studied previously in pediatric psoriasis patients. OBJECTIVE: We aimed to investigate the internalized stigma in pediatric psoriasis patients and to determine differences according to factors affecting internalized stigma compared to adult psoriasis patients. METHODS: This multicenter, cross-sectional, comparative study included 125 pediatric (55 female, 70 male; mean age±standard deviation [SD], 14.59±2.87 years) and 1,235 adult psoriasis patients (577 female, 658 male; mean age±SD, 43.3±13.7 years). Psoriasis Internalized Stigma Scale (PISS), Dermatology Life Quality Index (DLQI), Perceived Health Status (PHS), and the General Health Questionnaire (GHQ)-12 were the scales used in the study. RESULTS: The mean PISS was 58.48±14.9 in pediatric group. When PISS subscales of groups were compared, the pediatric group had significantly higher stigma resistance (p=0.01) whereas adult group had higher scores of alienation (p=0.01) and stereotype endorsement (p=0.04). There was a strong correlation between mean values of PISS and DLQI (r=0.423, p=0.001). High internalized stigma scores had no relation to either the severity or localization of disease in pediatric group. However, poor PHS (p=0.007) and low-income levels (p=0.03) in both groups, and body mass index (r=0.181, p=0.04) in the pediatric group were related to high PISS scores. CONCLUSION: Internalized stigma in pediatric patients is as high as adults and is related to poor quality of life, general health, and psychological illnesses. Unlike adults, internalized stigma was mainly determined by psoriasis per se, rather than disease severity or involvement of visible body parts, genitalia or folds.
