Alopecia Areata Different View; Heavy Metals
(Wolters Kluwer Medknow Publications, 2019) Ozaydin-Yavuz, Goknur; Yavuz, Ibrahim Halil; Demir, Halit; Demir, Canan; Bilgili, Serap Gunes
Background: Alopecia areata (AA) is a noncicatricial alopecia affecting any hair-bearing area. Although AA is considered to be an autoimmune disease, oxidative stress has been shown to be an important factor in the etiology of AA. Trace elements are highly essential for humans since they form the building blocks of large molecules, function as the cofactors of enzymes, and have some key biological functions. The aim of this study was to investigate serum levels of heavy metals like iron (Fe), zinc (Zn), manganese (Mn), copper (Cu), magnesium (Mg), cobalt (Co), cadmium (Cd), and lead (Pb) in patients with AA. Materials and Methods: The study included a patient group of 30 with AA and a control group of 31 healthy individuals. Serum levels of heavy metals were measured using atomic absorption spectrophotometry. Results: The 30 patients included 17 (56.7%) men and 13 (43.3%) women with a mean age of 33.8 (range, 19-48) years. Serum Zn and Mn levels were significantly lower and serum Cd, Fe, Mg, Pb, Co, and Cu levels were significantly higher in the patient group compared to that of the control group (P<0.05 for all). Conclusion: The results indicated that low levels of Zn and Mn are associated with AA while other metals were normal. So Zn supplementation may have some beneficial effect in AA while Fe prescription is fruitless.
Assessment of Heavy Metal and Trace Element Levels in Patients With Telogen Effluvium
(Wolters Kluwer Medknow Publications, 2018) Yavuz, Ibrahim Halil; Yavuz, Goknur Ozaydin; Bilgili, Serap Gunes; Demir, Halit; Demir, Canan
Background: Despite a multitude of studies, etiology of primary chronic telogen effluvium (TE) remains incompletely understood. Essential heavy metals are associated with beneficial effects in humans as well as in other living organisms. However, they may lead to toxic effects when the exposure exceeds the higher tolerable limits. We wanted to assess the heavy metal and trace element levels in patients with chronic TE. Materials and Methods: A total of 40 subjects with chronic TE were included in the study, and 30 healthy women served as control. General and dermatological examinations were taken up in all individuals. Those patients with positive hair pull test were evaluated with the help of a trichogram. The presence of >20% telogen hair as documented by trichogram was a requirement for the study inclusion. UNICAM-929 spectrophotometry device was used for determining serum trace element and heavy metal concentrations. Results: In spite of an absence of significant differences in terms of average Zn concentration, weight, or height between patients and controls, significant differences were noted for Cd, Fe, Mg, Mn, Pb, Co, and Cu (P<0.05). Conclusion: Our results suggest that heavy metals may play a causative role in the development of chronic TE. However, contrary to previous reports, zinc did not appear to play an important etiological role, while these patients had elevated serum iron levels.
Assessment of Hla-A, Hla-Dr, and Hla-Dq Alleles in Patients With Pemphigus Vulgaris From Eastern of Turkey
(Wiley, 2020) Dere, Gokturk; Yavuz, Ibrahim Halil; Ozaydin Yavuz, Goknur; Bayram, Yasemin; Gunes Bilgili, Serap; Ozturk, Murat
Background Pemphigus vulgaris (PV) is a chronic progressive autoimmune bullous disease caused by the interaction of pathogenic factors, genetic, and environmental factors. HLA alleles, which are considered as protective factors against disease or predisposing factors, may be different in various populations and ethnic groups. Aims The purpose of this study is to examine the HLA-A, HLA-DR, and HLA-DQ alleles in patients that are diagnosed with PV in and around eastern of Turkey and to determine the alleles that create predisposition to disease or protect against the disease. Patients/Methods Thirty patients diagnosed as PV with clinical, histopathological, and immunofluorescence findings and 30 healthy subjects were included in this study. The HLA-A, HLA-DR, and HLA-DQ typology in the DNA samples that were obtained from the blood samples of the groups was performed by using the PCR-SSP low-resolution gene panels. Results The HLA-A*03 allele was found to be significantly higher in patient group than the control group (P-value: .020). HLA-DRB1*04 and HLA-DRB1*14 alleles in PV patients were found to be significantly higher than the control group (P-value = .000). Conclusion It was concluded that the HLA-DRB1*03, HLADQB1*02, and HLA-DQB1*06 alleles in and around eastern of Turkey showed protective effects against pemphigus vulgaris. It was also concluded that the HLA-A*03, HLA-DRB1*04, HLA-DRB1*14, HLA-DRB4, HLA-DQB1*03, and HLA-DQB1*05 alleles could cause predisposition to the disease.

Comparison of Efficacy of Narrow Band Uvb Therapies With Uvb Alone, in Combination With Calcipotriol, and With Betamethasoneand Calcipotriol in Vitiligo
(Taylor & Francis Ltd, 2014) Akdeniz, Necmettin; Yavuz, Ibrahim Halil; Bilgili, Serap Gunes; Yavuz, Goknur Ozaydin; Calka, Omer
Objective: The purpose of this study is to compare the efficacy of three therapies in the treatment of non-segmental vitiligo: a combination of topical calcipotriol, narrowband-ultraviolet B (NB-UVB), and betamethasone therapies; a combination of NB-UVB and topical calcipotriol; and NB-UVB alone. Material and methods: Forty-five patients with non-segmental vitiligo presenting to our Dermatology clinic were recruited to participate in the study. Patients were randomly divided into three groups. For each patient the size of the depigmented areas was assessed according to the rule of nines. The first group was treated with a combination of topical calcipotriol, NB-UVB, and betamethasone therapies. The second group was treated with a combination of NB-UVB and topical calcipotriol and third group was treated with NB-UVB alone. Since the patients' vitiligo lesions had similar phototypes, all patients were started with 0.1 j/cm(2), regardless of their skin phototype. The dose of NB-UVB was increased 10% in each session and no further increment was done after reaching 2.5 j/cm(2). Treatment effectiveness was evaluated according to the percentage improvement in repigmentation. The quality of life of the patients was measured by the Dermatology Life Quality Index (DLQI). Results: The patients were aged from 13 to 55 years (mean: 25.29). The duration of disease ranged from 3 months to 20 years. Family history was positive for vitiligo in 10 patients (22.2%). The percentage of recovery after treatment was 63.33% +/- 7.55 in group 1, 60.67% +/- 5.75 in group 2, and 46.67% +/- 7.98 in group 3. There was no statistically significant difference between groups 1 and 2, and groups 2 and 3, but there was a statistically significant difference between groups 1 and 3 (p = 0.0048). Conclusions: In conclusion, NB-UVB-alone therapy and the combined therapies are effective treatment options in the treatment of vitiligo. Future studies with larger groups are warranted to confirm our results.
Cutaneous Reactions Caused by Nitrofurazone
(Termedia Publishing House Ltd, 2019) Bilgili, Serap Gunes; Ozaydin Yavuz, Goknur; Yavuz, Ibrahim Halil; Bilgili, Mehmet Ali; Karadag, Ayse Serap
Introduction: Allergic contact dermatitis (ACD) is a form of dermatitis due to type 4 hypersensitivity reaction that occurs when the skin comes into contacts with the topical product. Topical nitrofurazone is a widely used antimicrobial drug in our country which is well known to cause ACD. Aim: In this study, ACD cases with different clinical features attributed to the use of nitrofurazone were evaluated. Material and methods: Patients hospitalized in our clinic between 2013 and 2017 with ACD diagnosis due to nitrofurazone were evaluated. The patient age, gender, atopy histories, clinical features, dissemination of the lesions, treatment given were reviewed. Results: In a 5-year period, 58 cases were identified and their data were analysed. Twelve patients were female (21%), 46 patients were male (79%). Clinical presentations were dyshidrosiform (45%), excoriated papules and plaques (33%), combined (21%), and erythroderma in one patient. The dissemination was generalized in 34 patients, localized in 14 patients, and local spread in 10 patients. The mean hospitalization time was 7 +/- 3 days, and ranged from 3 to 18 days. Conclusions: There may be widespread and severe ACD due to the use of nitrofurazone. Topical nitrofurazone should not be applied on damaged skin as sensitization may develop. Patients and physicians should be aware of the ACD risk associated with topical nitrofurazone, which is also commonly used as self-medication, physicians should take a detailed history of the drug use and products containing nitrofurazone should not be used in conditions where skin integrity is not intact, whenever possible.
Effects of Omalizumab on Serum Levels of Substance P, Calcitonin Gene-Related Peptide, Neuropeptide Y, and Interleukin-31 in Patients With Chronic Spontaneous Urticaria
(Wiley, 2023) Boyvadoglu, Cagdas; Ulusal, Hasan; Taysi, Seyithan; Ozaydin-Yavuz, Goknur; Yavuz, Ibrahim Halil; Korkmaz, Pinar; Inaloz, Huseyin Serhat
The mechanism of action of omalizumab in urticaria is still not literally known. This study examines the serum values of substance P (SP), calcitonin gene-related peptide (CGRP), neuropeptide Y (NPY), and interleukin-31 (IL-31) in patients using omalizumab. In this study, 30 patients with chronic spontaneous urticaria (CSU) who were going to be treated with omalizumab and 20 healthy volunteers took part. Demographic data, clinical data, and disease activity scores were noted. For serum SP, CGRP, NPY, and IL-31 values, 10 mL of blood were taken from the patients before starting the treatment, 3 months after the treatment, at the end of the 6th month, and from healthy volunteers all at once. The change in values measured at baseline, 3rd month, and 6th month was analyzed by the Friedman Test. The Mann-Whitney U test was used to compare the parameters obtained from the patients and control groups. The significance level was set at p=0.05. SP, CGRP, NPY, and IL-31 values were all statistically significantly lower in the CSU patient group compared to the control group. After treatment, the levels of SP and CGRP in the serum went up, and the levels of serum IL-31 went down. These changes were statistically significant. This study supports the view that omalizumab does not only affect IgE receptors but also affects mast cells through other mechanisms. According to our knowledge, this is the first study to show that omalizumab therapy and serum CGRP levels are related.
Evaluation of Hirsutism and Hormonal Parameters in Acne Vulgaris Patients Treated With Isotretinoin
(Wiley-hindawi, 2021) Aktar, Rojda; Gunes Bilgili, Serap; Yavuz, Ibrahim Halil; Ozaydin Yavuz, Goknur; Aktar, Sirac; Ozturk, Murat; Karadag, Ayse Serap
Background Although the effect of isotretinoin use on hormonal changes in acne pathogenesis is not fully known, there are limited studies on its effects on the development of hirsutism. In this study, it was aimed to evaluate the effect of isotretinoin use on hirsutism and hormonal parameters in patients with acne vulgaris. Methods In this study, 30 female acne patients and 30 healthy females were evaluated prospectively. Menstrual irregularity, LH, FSH, prolactin, progesterone, 17-OH progesterone, oestradiol, total testosterone, DHEA-S, insulin, glucose, TSH levels, Ferriman-Gallwey (FG) score and ultrasonography (USG) findings of control group and patient group were recorded. Results Pre-treatment progesterone (P = .007) and oestradiol (P = .001) levels of the patients were statistically lower than the control group. In the patient group, menstrual irregularity (P < 001) and FG hirsutism score at the third month of treatment were significantly higher than before treatment. In 10% of the patients, there were abnormal findings on pelvic USG in the third month of treatment. Conclusion In our study, it could not be revealed that isotretinoin has a significant effect on pituitary, adrenal hormones and insulin resistance. We found that 3 months of isotretinoin treatment caused an increase in menstrual irregularity and FG hirsutism score.

(Turkish J Pediatrics, 2020) Cetin, Mecnun; Yavuz, Ibrahim Halil; Yavuz, Goknur Ozaydin; Karaman, Kamuran
Psoriasis is a chronic inflammatory disorder affecting the skin, nails, and joints. Its lifetime prevelance has been estimated to be at 1% to 3%. This study was designed to examine the association between serum pentraxin 3 (PTX3) and cardiovascular function in psoriatic children. Thirty-three children who were diagnosed with psoriasis, and 29 healthy children, between 4 and 18 years of age, were included in the study. Both patient and control group was evaluated by the pulsed wave tissue doppler imaging (TDI) echocardiography as well as with conventional Doppler echocardiography (CDE). PTX3 values of the groups were evaluated. There was no difference between cases and controls for age (9.67 +/- 3.72, 9.60 +/- 2.84 years, p=0.916, respectively). In evaluation of the left ventricle (LV) CDE; A wave, isovolumic relaxation time (IVRT) and myocardial performance index (MPI) were significantly higher in the study group (p<0.05). Ejection time (ET) was significantly lower in the study group compared to the control group (p<0.05). In evaluation of LV TDI; Deceleration time (DT'), IVRT', E/E' and MPI' were found to be significantly higher in the study group (p<0.05). In addition to, E', E'/A' and ET' were siginificantly lower in study group. PTX3 level was significantly higher in the study group compared to the control group (p=0.009) (Table III). However, no correlation was found between PTX3 level and cardiovascular parameters. In conclusion; both doppler echocardiography and PTX3 may be useful tools for the screening of cardiovascular (CV) risk in these patients. Psoriasis itself may be an independent risk factor for cardiac dysfunction in the pediatric population.

(Korean dermatological Assoc, 2020) Alpsoy, Erkan; Polat, Mualla; Yavuz, Ibrahim Halil; Kartal, Pelin; Balci, Didem Didar; Karadag, Ayse Serap; Senol, Yesim
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.
Investigation of Galectin-3, Lipocalin 2, Retinol Binding Protein (Rbp), Small Dense Low-Density Lipoprotein (Sdldl) in Patients With Hirsutism
(Termedia Publishing House Ltd, 2019) Yavuz, Ibrahim Halil; Ozaydin Yavuz, Goknur; Cokluk, Erdem; Kurtoglu, Zehra; Bilgili, Serap Gunes
Introduction: Hirsutism is defined as excessive terminal hair in androgen-dependent areas in women. Adipose tissue is no longer regarded as a storage site for triglycerides or as a source of free fatty acids but is currently emerging as a key constituent of energy metabolism secreting numerous enzymes, cytokines, growth factors, and hormones. Aim: To evaluate serum levels of galectin-3 (Gal3), lipocalin-2 (LCN2), retinol binding protein (RBP), and small dense low-density lipoprotein (sdLDL) in patients with hirsutism and patients co-presenting with polycystic ovary syndrome (PCOS) and hirsutism. Material and methods: The study included 90 patients that were divided into three groups: (I) patients with idiopathic hirsutism (IH) (n = 30), (II) PCOS patients with hirsutism (H-PCOS) (n = 30), and (III) the control group (n = 30). Informed consent was obtained from each participant. Idiopathic hirsutism was scored using the modified Ferriman-Gallwey (mFG) scoring system and the diagnosis of PCOS was established based on the modified Rotterdam criteria. Human Gal3, LCN2, RBP, and sdLDL levels were analysed using a commercially available double-antigen sandwich enzyme-linked immunosorbent assay. Results: No significant difference was found between the three groups with regard to serum Gal3, LCN2, RBP, and sdLDL levels (p > 0.05). Median values were higher in the H-PCOS group than in the other two groups: body weight (median: 76.5 kg) (p < 0.001), waist circumference (median: 82.5 cm) (p = 0.001). Conclusions: No significant correlation was found between the adipokines that play a role in the aetiology of numerous diseases and some mediators of the lipid metabolism and hirsutism.
Omalizumab Is Not Just an Anti-Immunoglobulin E
(Taylor & Francis Ltd, 2022) Ozaydin-Yavuz, Goknur; Yavuz, Ibrahim Halil; Inaloz, Huseyin Serhat; Boyvadoglu, Cagdas
Introduction and purpose The mechanism of omalizumab in urticaria is not literally known. Omalizumab may affect receptors on the mast cell surface in other ways, especially other than Fc epsilon RI. Materials and Methods Thirty patients who were treated with omalizumab with the diagnosis of chronic urticaria were included in the study. For serum vasoactive intestinal peptide (VIP), kallikrein (KAL), and substance p (SP) values, 5 mL of blood was taken from the patients. These bloods were centrifuged for 5 min and stored at -80 degrees until the levels were measured. The changes in values measured at baseline, third month, and sixth month were analyzed by Friedman test. A value of p < 0.05 was considered statistically significant results. Results While SP, KAL, and VIP values increased continuously, it was observed that the D-dimer value decreased. Conclusion This study shows that omalizumab can affect mast cells other than IgE. To the best of our knowledge, this is the first study to show the relationship between omalizumab and VIP.
The Role of Pentraxin 3 in Pemphigus Vulgaris
(Termedia Publishing House Ltd, 2020) Yavuz, Ibrahim Halil; Yavuz, Goknur Ozaydin
Introduction: Pemphigus is a group of autoimmune bullous diseases caused by antibodies directed against the desmosomal adhesion molecules desmoglein land 3, which are required for intercellular adhesion of keratinocytes. Pentraxins are a group of proteins that function as pattern recognition molecules and also play a role in humoral innate immunity. Pentraxin 3 (PTX3) is the prototype of the long pentraxins and has been shown to be increased in numerous autoimmune diseases. Aim: To investigate whether PTX3 can be used as a marker of PV caused by autoimmunity and resulting in tissue injury. Material and methods: The study included 30 patients who presented to the University Medical School Dermatology Department and were diagnosed with PV based on clinical, histological, and immunological findings. The control group included 30 healthy individuals. Human PTX3 concentration was measured with a commercially available ELISA kit, using a double antibody sandwich enzyme-linked immunosorbent assay. Results: The 60 participants comprised 31 (52%) men and 29 (48%) women. The most common site of onset was mucosa + skin (n = 22; 73.3%) and a psychological pathology was present in 7 (23.3%) patients. Median PTX3 level was significantly higher in the PV group compared to the control group (p = 0.008). The ROC curve analysis indicated a significant area under curve (AUC) value for serum PTX3 level in the prediction of PV. Conclusions: PTX3 was found to be increased in PV and PTX3 could be a useful indicator of disease activity in PV.
