RESUMEN
BACKGROUND: Psoriasis is a chronic inflammatory disease that is associated with many inflammatory conditions such as atherosclerosis, hypertension, among others. SCUBE-1 is a protein that plays a role in angiogenesis. OBJECTIVES: The present study aimed to investigate whether SCUBE-1 could indicate subclinical atherosclerosis in psoriatic patients, and to compare SCUBE-1 levels, measurement of carotid artery intima-media thickness (CIMT), and metabolic parameters in psoriasis patients and healthy controls. METHODS: Forty-six patients with psoriasis and 43 healthy controls were included. The severity of the disease was assessed with Psoriasis Area Severity Index (PASI) in the patient group. Levels of SCUBE-1, CRP, lipids, and fasting glucose were measured with the enzyme-linked immunosorbent assay (ELISA) method, and CIMT measurements were performed by the same cardiologist. RESULTS: SCUBE-1 levels and CIMT values were significantly higher in the patient group (for both p < 0.05). Moreover, systolic blood pressure, CRP levels, and waist circumference were higher in the patient group even though both groups had similar BMIs (for all p < 0.05). A positive correlation was found between SCUBE-1 and CIMT values among patients, and multiple regression analyses revealed that SCUBE-1 and CIMT are significantly associated with psoriasis as well. STUDY LIMITATIONS: A low number of participants and not including any other inflammatory marker related to angiogenesis or atherosclerosis such as VEGF, adiponectin are the main limitations of the present study. CONCLUSION: Despite the severity of the disease, even in psoriasis patients with mild disease the SCUBE-1 level may be an indicator of subclinical atherosclerosis and indicate the risk of cardiovascular disease in the future.

INTRODUCTION: Psoriasis is a chronic inflammatory dermatological disease with complex pathogenesis in which many immune system cells, including keratinocytes, play a role. Many genes regulate the proliferation of keratinocytes and other immune cells that have essential roles in the pathogenesis of psoriasis. The expressions of EREG, PTPN1, and SERPINB7 genes were shown as upregulated in psoriatic skins in a few studies previously. OBJECTIVES: We aimed to evaluate the expressions of these genes in psoriatic lesional skin and compared them with non-lesional adjacent skin of the same patients and normal skin of healthy controls. RESULTS: Our results revealed that the expressions of EREG and PTPN1 genes were upregulated, whereas the SERPINB7 gene expression was down regulated in the psoriatic skin of the patients than normal skin of controls. Moreover, the expression level of the SERPINB7 gene was also negatively correlated with the severity of the disease among patients. CONCLUSIONS: According to our results, overexpression of EREG and PTPN1 genes, and decreased expression of SERPINB7 gene may lead to the development of psoriasis.
RESUMEN
BACKGROUND: The differentiation between the pemphigoid diseases is essential for treatment and prognosis. In Turkey, data on the incidence of these diseases are insufficient. Our aim in this study is to determine the incidence, demographics and clinical characteristics associated with diseases of the pemphigoid group. METHODS: We prospectively analysed 295 patients with pemphigoid who visited dermatology clinics of tertiary referral hospitals in 12 different regions of Turkey within a year. The diagnosis was based on clinical, histopathological, direct immunofluorescence (DIF) and serological (multivariant enzyme-linked immunosorbent assay [ELISA], indirect immunofluorescence and mosaic-based BIOCHIP) examinations. Clinical and demographic findings, aetiological factors and concomitant diseases observed in the patients were recorded. RESULTS: A total of 295 (female/male ratio: 1.7/1) patients with pemphigoid were diagnosed in 1-year period. The overall incidence rate of pemphigoid diseases was found to be 3.55 cases per million-years. The ratio of pemphigoid group diseases to pemphigus group diseases was 1.6. The most common pemphigoid type was bullous pemphigoid (BP, 93.2%). The others were epidermolysis bullosa acquisita (3.1%), pemphigoid gestationis (2.4%), linear IgA disease (1%) and mucous membrane pemphigoid (0.3%). The most common (26.8%) possible trigger of the bullous pemphigoid was gliptin derivative drugs. The most common concomitant diseases with pemphigoid were cardiovascular (27.8%) and neurological diseases (23.7%). CONCLUSIONS: This study showed that the increased frequency of bullous pemphigoid reversed the pemphigoid/pemphigus ratio in Turkey. Further studies are warranted regarding the reasons for this increase.

Background/aim: Although the cause of immune activation in the pathogenesis of psoriasis is still unclear, miRs are thought to have an effect on psoriasis. This work aimed to evaluate the role of miRs (miR-4649-3p, miR-6867-5p, miR-4296, miR-210, and miR-1910-3p) that target the FOXP3 mRNA and IL-17A mRNA in psoriasis. Materials and methods: Forty-four psoriasis patients and 44 healthy controls were included in the study. Quantitative real-time PCR (qRT-PCR) was used for the measurement of miRs. Serum IL-17A levels were determined by an enzyme-linked immunosorbent assay (ELISA) method. Results: Plasma miR-1910-3p levels were significantly lower in the patient group than the controls (P = 0.000, fc: 0.10). ROC analysis showed that plasma miR-1910-3p levels could significantly differentiate psoriasis patients from healthy controls [AUC = 0.912 (0.848 0.975), P = 0.000]. The plasma miR-4649-3p level was significantly higher in the psoriasis group compared to the controls (P = 0.000, fc: 2.99). Conclusion: Decreased expression of miR-1910-3p increases the risk of developing psoriasis by approximately 50-fold and was able to use for the significant differentiation of psoriatic patients from healthy controls.

Abstract Background Psoriasis is a chronic systemic inflammatory disease frequently associated with serious comorbidities. Objectives To investigate the systemic inflammatory burden in psoriasis and to assess the correlation between traditional and novel inflammatory markers and the severity of the disease. Methods This cross-sectional study was conducted on 60 patients with psoriasis vulgaris and 50 healthy volunteers. Data including demographics, Psoriasis Area and Severity Index scores, and laboratory results were analyzed and compared. Results Compared with the control group, the psoriatic patients had significantly higher high sensitive C-reactive protein, serum amyloid A, erythrocyte sedimentation rate, leukocyte, neutrophil, neutrophil-to-lymphocyte ratio, monocyte to high density lipoprotein (HDL) cholesterol ratio, and aspartate aminotransferase levels, and significantly lower HDL cholesterol levels (p < 0.05). No significant difference was found in procalcitonin, lymphocyte, monocyte, hemoglobin, red blood cell distribution width, platelet, mean platelet volume, platelet distribution width, lymphocyte-to-monocyte ratio, anti-cyclic citrullinated peptide, glucose, alanine aminotransaminase, blood urea nitrogen, creatinine, triglyceride, total cholesterol, and LDL cholesterol levels between the two groups (p > 0.05). The Psoriasis Area and Severity Index score was positively correlated with high-sensitivity C-reactive protein, serum amyloid A, and monocyte to HDL cholesterol ratio, and negatively correlated with lymphocyte-to-monocyte ratio (p < 0.05). Study limitations This was a single-center study with relatively limited numbers of patients and controls. Conclusions The data show that high sensitivity C-reactive protein, serum amyloid A, erythrocyte sedimentation rate, neutrophil-to-lymphocyte ratio, and monocyte to HDL cholesterol ratio can be used as markers of systemic inflammation in patients with psoriasis. Moreover, high sensitivity C-reactive protein, serum amyloid A, monocyte to HDL cholesterol ratio and lymphocyte-to-monocyte ratio are closely related to the Psoriasis Area and Severity Index score, and they may be regarded as objective indicators in determining the disease severity.

Background/aim: Verruca vulgaris is a benign disease characterized with papillomas on the skin and mucosa. The aim of this study was to investigate the serum levels of coenzyme Q10, MDA, and zinc as well as the lipid profile of verruca vulgaris patients and examine the relationship between these parameters and clinical manifestations of the disease. Materials and methods: The study included 49 verruca vulgaris patients (mean age: 32.01 ± 14.20 years; 22 males, 27 females) and 40 healthy volunteers (mean age: 31.63 ± 8.98 years; 21 males and 19 females). Coenzyme Q10 levels were assessed by using an enzyme- linked immunosorbent assay. Serum MDA levels were measured spectrophotometrically. Zinc levels were measured using a Perkin Elmer AAnalyst 800 atomic absorption spectrometer with a deuterium background correction and additional standard techniques. Results: The coenzyme Q10 levels were found to be higher in the verruca vulgaris group compared to the healthy volunteers. However, this increase was not statistically significant (P = 0.195). Zinc levels were significantly lower in the verruca vulgaris group compared to the healthy volunteers (P = 0.002). In the patient group, MDA levels and HDL levels were significantly higher compared to the healthy volunteers (P = 0.023 and P = 0.004, respectively). Additionally, there was no statistically significant difference between the groups in the CoQ10/Total cholesterol ratio (P = 0.433). Conclusion: Reduced serum zinc levels and increase of oxidative stress in verruca vulgaris may be a factor responsible for development of verruca vulgaris.

Background/aim: IL-23R gene polymorphisms and the association of these polymorphisms with serum IL-23 levels were investigated in patients with psoriasis in the current study. Materials and methods: Sixty-seven patients with psoriasis who were admitted to our dermatology outpatient clinic and 67 healthy controls were included in the study. Polymorphisms of the IL-23R gene were determined by KASP-PCR method, and serum IL-23 levels were determined by ELISA method. Results: The distribution of IL-23R gene polymorphisms rs2201841, rs11209026, rs7530511, rs1343152, and rs11465804 was not significantly different in the patient and control groups. The AA genotype of the rs2201841 locus in males and the GA genotype in females, as well as the AA genotype of the rs1343152 locus in males and the CA genotype in females, were statistically significant in patients with psoriasis. The mean serum IL-23 level was significantly lower in the patient group (42.62 ± 5.96) compared to the control groups (75.76 ± 13.24). Conclusion: IL-23R gene polymorphisms including rs2201841, rs11209026, rs7530511, rs11465804, and rs1343152 were not found to be significantly related to psoriasis. Different genetic polymorphisms may play a role in the development of psoriasis in female and male populations. Ethnic differences between different populations may have led to differences in the distribution of polymorphisms in the current study with compared to other published studies. Additionally, many different genes, polymorphisms, and environmental factors that have an effect on the development of psoriasis may affect the disease process.

BACKGROUND: The effects of isotretinoin on suicide, social anxiety and obsessive-compulsive symptoms in adolescents with acne have not been sufficiently investigated. OBJECTIVE: This study aimed to evaluate the quality of life, depression, anxiety, suicide, social anxiety, and obsessive-compulsive symptoms of adolescents receiving systemic isotretinoin and antibiotic treatments at baseline and at 3 months. METHODS: The study included a total of 102 adolescents using isotretinoin (n = 60) and antibiotics (n = 42). The Acne Quality of Life Scale (AQLS), Hospital Anxiety and Depression Scale (HADS), Suicide Probability Scale (SPS), Liebowitz Social Anxiety Scale (LSAS), and Maudsley Obsessive-Compulsive Question List (MOCQL) were administered to both groups at baseline and at 3 months. In order to exclude patients with comorbid psychiatric disorders, the patients were evaluated at the beginning of the study with the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL). RESULTS: There were no significant differences in the mean age, gender distribution, educational level, and family history of mental illness between the two groups. There were significant decreases in the Global Acne Grading System scores, visual analogue scale scores, AQLS scores, total and subscale scores of LSAS, and total and subscale scores of MOCQL at 3 months compared with baseline in both groups. However, there were no significant changes in the total and subscale scores of HADS and total and subscale scores of SPS at 3 months compared with baseline in both groups. CONCLUSION: We found that neither isotretinoin nor antibiotic treatment affected the levels of depression, anxiety, and suicide in acne patients. Moreover, both isotretinoin and antibiotic treatment were shown to improve the quality of life, social anxiety, and obsessive-compulsive symptoms in acne patients. However, clinicians should be careful about psychiatric side effects in patients using isotretinoin. Further studies with a larger number of cases and with a longer follow-up period are needed to investigate the complex effects of isotretinoin on the central nervous system.

BACKGROUND: Since adolescents are psychologically more unstable, the emergence of acne vulgaris during adolescence makes this disease a focal point of concern for many individuals. AIM: In this study, psychiatric comorbidity and levels of self-injurious behavior, suicide probability, life satisfaction, self-esteem and loneliness in adolescents with acne was assessed and compared with a control group. METHODS: The study was conducted with 104 adolescents with acne and 102 age- and sex-matched healthy controls. The Rosenberg Self-Esteem Scale, Suicide Probability Scale (SPS), Life Satisfaction Inventory, Short form of the UCLA Loneliness Scale and Inventory of Statements About Self-Injury (ISAS) were administered to the case and control groups. Both groups were assessed according to the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version-Turkish Version. RESULTS: Adolescents with acne were found to have lower levels of self-esteem and life satisfaction and higher levels of loneliness compared to controls. The mean scores of SPS and its negative self-evaluation/hostility subscales were found to be significantly higher in adolescents with acne. The presence of self-injurious behavior and psychiatric comorbidity were shown to be significantly higher in adolescents with acne. CONCLUSIONS: The presence of high levels of psychiatric comorbidity, suicide probability, and self-injurious behavior in adolescents with acne in our study suggests that psychiatric evaluation should be included in acne treatment plans. Psychological assessment of adolescents with acne vulgaris is important for contributing to the detection of any potential covert sexual abuse. Our study demonstrates the importance of a multidisciplinary approach for acne treatment.

H1-receptor inhibiting drugs, namely loratadine and cetirizine, were frequently used in treatment of chronic urticaria. Urticarial weal and flare reactions, a neurogenic reflex due to neuropeptides, were reported to be more effectively inhibited by cetirizine than loratadine. The aim of this study was to determine and compare the effects of systemic loratadine and cetirizine treatments on serum levels of selected neuropeptides in chronic urticaria. Treatment groups of either systemic loratadine or cetirizine (10 mg/d), consisting of 16 and 22 patients, respectively, were included. Serum levels of stem cell factor (SCF), neuropeptide Y (NPY), calcitonin gene-related peptide (CGRP), nerve growth factor (NGF), vasoactive intestinal peptide (VIP), and substance P (SP) were detected before and after one week of treatment with antihistamines. Serum NPY and VIP levels were significantly decreased when compared before and after treatment with antihistamines (P < 0.001 and P < 0.01, respectively). SCF and NGF values were also decreased after antihistamine treatment (P < 0.05). Post-treatment levels of CGRP were significantly higher compared with pretreatment values, while no significant difference was detected between pre and post treatment levels of SP. Cetirizine was significantly more effective than loratadine on lowering serum levels of SCF among the other neuropeptides. Systemic loratadine and cetirizine treatments in patients with chronic urticaria precisely caused variations in serum levels of neuropeptides. The predominant effect of cetirizine compared to loratadine on reducing serum SCF levels might be explained with anti-inflammatory properties of cetirizine.

Psoriasis is a chronic inflammatory process associated with an increased risk of cardiovascular risk factors. sCD40L has been suggested to have a possible role in the pathogenesis, of psoriasis and is known to be associated with inflammation, atherogenesis and cardiovascular events. This study investigated cardiovascular risk factors (sCD40L and homocysteine) as well as subclinical atherosclerosis indicators in psoriatic patients and control subjects. The study included 56 consecutive patients with chronic plaque-type psoriasis and 53 age and gender matched healthy controls admitted to a university hospital. Serum sCD40L and homocysteine levels were measured by ELISA. Carotid artery intima-media thickness and brachial artery flow mediated dilatation (FMD) measurements were determined ultrasonographically. Subjects who had a history of cardiovascular diseases and cardiovascular risk factors and receiving any systemic treatment were excluded from the study. Plasma sCD40L levels were significantly higher in psoriasis patients compared with healthy controls (1.33±0.72 vs. 0.98±0.70 ng/ml P=0.012), whereas plasma homocysteine levels did not differ significantly between the two groups. FMD was significantly reduced in the psoriasis group compared to the controls (3.83±5.03 vs. 8.45±7.27% P=0.0001). Multiple linear regression analyses indicated a significant association between psoriasis, sCD40L, and FMD. Psoriatic patients had higher sCD40L levels than healthy controls, which may lead to an increase in cardiovascular diseases. sCD40L may be a more reliable and early predictive marker of cardiovascular events in psoriatic patients. New treatmentoptions that will be developed over sCD40L will benefit in prevention of psoriasis and its cardiovascular comorbidities.

Behcet's disease (BD) is a chronic, inflammatory, and multisystemic condition although its pathogenesis is uncertain. Main component of St. John's wort (Hypericum perforatum, HP) is hyperforin and induces antiinflammatory and antioxidant properties. We aimed to investigate effects of HP on oxidative stress, apoptosis, and cytosolic-free Ca²âº [Ca²âº](i) concentration in neutrophil of BD patients. Nine new-diagnosed active patients with BD and nine control subjects were included in the study. Disease activity was considered by clinical findings. Neutrophil samples were obtained from the patients and controls. The neutrophils from patients were divided into three subgroups and were incubated with HP, voltage-gated calcium channel (VGCC) blockers, (verapamil+dilitiazem) and non-specific TRPM2 channel blocker (2-aminoethyl diphenylborinate, 2-APB), respectively. The neutrophils were stimulated by fMLP as a Ca²âº-concentration agonist and oxidative stress former. Caspase-3, caspase-9, apoptosis, lipid peroxidation, and [Ca²âº](i) values were high in the patient groups, although cell viability, glutathione (GSH), and glutathione peroxidase (GSH-Px) values were low in patient group. However, the [Ca²âº](i), caspase-3, and caspase-9 values decreased markedly in patient+HP group although GSH and GSH-Px values increased in the group. The [Ca²âº](i) concentration was also decreased in the patient group by V+D, 2-APB, and HP incubations. In conclusion, we observed the importance of neutrophil Ca²âº entry, apoptosis, and oxidative stress through gating VGCC and TRPM2 channels in the neutrophils in the pathogenesis and activation of the patients with BD. HP induced protective effects on oxidative stress by modulating Ca²âº influx in BD patients.

BACKGROUND: The aim of this study was to examine the personality characteristics of patients with Behcet's Disease (BD) using the Temperament and Character Inventory (TCI) compared with healthy control subjects and to investigate the relationship between the temperament and character properties and quality of life, disease activity, depression and anxiety in Behcet's patients. METHODS: A total of 46 BD patients and 40 healthy subjects were included in the study. All patients and controls were determined using the TCI, Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders Clinical Version for Axis I disorders (SCID-CV), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Quality of life (QOL) Instrument for Skin Disorders and Behcet Disease Current Activity Form (BDCAF). RESULTS: BD patients demonstrated significantly lower Reward Dependence than healthy controls. Among the subscales; Explarotory Excitability, Shyness with Strangers, Attachment, Spiritual Acceptance were lower and Self-Acceptance was higher in patients compared to control subjects. Decreased quality of life and increased disease activity of the patients were correlated with increased anxiety and depression. Responsibility, Self-Forgetfulness and Transpersonal Identification were associated with quality of life while Responsibility was the major factor effecting QOL. Disease activity was not found related with TCI properties. CONCLUSION: Temperament and Character traits of BD patients were different from healthy group that might be due to many factors like genetics, biological or socio-cultural differences. BD patients were demonstrated as materialistic, self-contained, self-confident, cold, detached, and reserved although they are not shy. Considering the different personality traits of BD patients in psychotherapeutic approaches, may have a positive impact on QOL and comorbid major depressive disorder.

BACKGROUND: The pathophysiology of chronic idiopathic urticaria (CIU) is not fully understood; however, it has been hypothesized that a subset of people with CIU may have an autoimmune disease and that peripheral cutaneous nerve fibers may be involved in CIU. Similarly, it has been postulated that fibromyalgia syndrome (FMS) is an autoimmune disorder and may be associated with alterations of peripheral cutaneous nerve fibers. Accordingly, the present study aimed to determine whether the frequency of FMS is higher in patients with CIU. MATERIAL/METHODS: A total of 72 patients with CIU and 67 sex- and age-matched healthy controls were included. Urticaria activity score (UAS), fibromyalgia impact questionnaire (FIQ), tender point number, and visual analogue scale (VAS) were assessed. RESULTS: The frequency of FMS was similar between the groups (9.7% vs. 4.5%, p=0.32). However, symptom duration of FMS was significantly longer, and tender point number and FIQ were significantly higher in patients with CIU than in controls. In addition, patients with CIU had significantly higher VAS scores. UAS was significantly correlated with presence of FMS, symptom duration of FMS, tender point number, and FIQ and VAS scores. Logistic regression analysis revealed that UAS was an independent predictor of presence of FMS (b=0.34, p=0.003). CONCLUSIONS: Frequency of FMS was slightly, but not significantly, higher in patients with CIU than in controls. However, symptom duration of FMS, tender point number, and FIQ and VAS scores were significantly higher in patients with CIU, and UAS reflecting severity of the disease was significantly and independently associated with presence of FMS.

Psoriasis is a chronic, immune-mediated skin disease characterized by production of reactive oxygen species due to the activation of tumor necrosis factor alpha (TNF-α), which is thought to be an important factor in inducing and maintaining psoriatic lesions. As an external factor, ultraviolet B (UVB) radiation stimulates TNF-α production and secretion by human keratinocytes in vitro and can also reach the upper dermis and suppress endothelial cells in vitro. The selenium level in psoriatic patients has been found to be lower than expected, but studies on its role in the pathogenesis of the disease are scarce. Selenium can influence immune response by changing the expression of cytokines and their receptors or by making immune cells more resistant to oxidative stress. It was reported that selenium supplementation had inhibitory effects on TNF-α levels in patients with psoriasis, but the details are not completely elucidated. Selenium compounds are also known to prevent the in vitro release of UVB-induced proinflammatory cytokines by inhibition of mRNA in human keratinocytes. In the present review, the protective role of selenium in oxidative stress, lesions, and immune system regulation in patients with psoriasis is summarized.

Acne vulgaris is the one of the most common skin diseases. Although isotretinoin (13-cis-retinoic acid) is an effective and well-tolerated medication, it has a wide range of side effects. Because the effects of isotretinoin on oxidant and antioxidant systems have not yet been clarified, we investigated plasma and erythrocyte antioxidant vitamins, lipid peroxidation (LP), reduced glutathione (GSH) and glutathione peroxidase (GSH-Px) values in patients with acne vulgaris before and after isotretinoin treatment. The study was performed on the blood plasma and erythrocytes of 31 acne vulgaris patients. Blood samples were taken from the patients before treatment and after isotretinoin (oral and 0·5-0·7 mg·kg(-1)) treatment for 2 months. Plasma amtioxidant vitamins, erythrocyte malondialdehyde, GSH and GSH-Px levels were measured. Plasma vitamin E (p < 0·001), lipid peroxidation (LP) and serum high-density lipoprotein cholesterol (p < 0·001) values were significantly lower in the treatment group than in the pre-treatment group, although erythrocyte LP (p < 0·001), GSH (p < 0·01) and GSH-Px (p < 0·001), aspartate aminotransferase (p < 0·05), alanine aminotransferase (p < 0·05), density lipoprotein cholesterol (p < 0·001) and total cholesterol (p < 0·01) levels were significantly higher in the treatment group than in the pre-treatment group. Vitamins A, C and ß-carotene concentrations did not change significantly between the two groups. In conclusion, the results of the current study indicate that isotretinoin treatment induces oxidative stress and liver damage by decreasing plasma vitamin E and increasing erythrocytes GSH-Px, GSH and liver enzyme values.

Behçet disease (BD) is a chronic, inflammatory, and multisystemic condition with an uncertain pathogenesis. One of the major immunologic findings in BD pathogenesis is increase in activity of neutrophil. An increase in the cytosolic free Ca²âº[Ca²âº](i) concentration that induces Ca²âº signaling is an important step that participates in the neutrophil activation and reactive oxygen species production that leads to tissue damage in body cells. We aimed to investigate the effects of colchicine on oxidative stress and Ca²âº release in serum and neutrophil of BD patients with active and inactive periods. Twelve Behçet patients (6 active and 6 inactive) and 6 control subject were included in the study. Disease activity was considered by clinical findings. Serum and neutrophil samples were obtained from the patients and control subjects. Neutrophils from patients with active BD were divided into three subgroups and were incubated with colchicine, verapamil + diltiazem, and colchicine + verapamil + diltiazem, respectively. Erythrocyte sedimentation rate, leucocytes counts, serum C-reactive protein, neutrophil, and serum lipid peroxidation and intracellular Ca²âº release levels were higher in active and inactive groups than in the control group, although their levels were lower in active group than in inactive group. However, neutrophil Ca²âº release levels were decreased in colchicine, verapamil + diltiazem, and colchicine + verapamil + diltiazem groups group compared to active group. Serum glutathione, vitamin A, vitamin E, and ß-carotene concentrations were lower in active and inactive groups than in the control group, although serum vitamin E and ß-carotene concentrations were higher in the inactive group than in the active group. Neutrophil and serum glutathione peroxidase activity within the three groups did not change. In conclusion, we observed the importance of Ca²âº influx into the neutrophils and oxidative stress in the pathogenesis and activation of the patients with BD. Colchicine induced protective effects on oxidative stress by modulating Ca²âº influx in BD patients.
