RESUMO
BACKGROUND: Psoriasis is a multifactorial, chronic inflammatory skin disease where genetic and environmental factors play a role in the pathogenesis. Smoking is one of the critical environmental factors triggering psoriasis. OBJECTIVE: The purpose of the present study was to analyse the smoking habits of patients with psoriasis and the effect of smoking on disease characteristics. METHODS: One hundred and thirty-three patients who applied to the department of Dermatological and Venereal Diseases, Ankara Numune Education and Research Hospital, between May 2018 and May 2019 and were diagnosed with psoriasis participated in the study. Clinical, demographical, and treatment-related characteristics, and smoking habits of patients were recorded. RESULTS: Sixty-seven point six percent of psoriasis patients were smokers. The presence of moderate to severe psoriasis (P = .028), nail involvement (P = .004), administration of systemic treatment (P = .024) and additional cardiovascular disease (P = .038) frequencies was higher in smokers compared to non-smokers. Besides, a positive correlation was observed between the amount of smoking and psoriasis area and severity index (PASI) (P = .003; r = .32). CONCLUSIONS: Smoking has many negative effects on patients with psoriasis including higher PASI levels, increased frequency of nail involvement, and cardiovascular diseases. Questioning cigarette smoking in psoriatic patients and supporting smoking cessation may contribute to reducing the adverse impact of smoking on psoriasis.

BACKGROUND: Vitiligo is an autoimmune disease characterised by acquired loss of melanocytes. Although the pathogenesis of vitiligo remains unknown, oxidative stress and autoimmune dysregulations are considered to play a role. OBJECTIVE: The aim of this study was to evaluate the HLA profile and total antioxidant capacity (TAC) and their relationship to clinical characteristic of vitiligo patients. METHODS: Ninety-one vitiligo patients and 100 healthy controls were included in the study. We analysed HLA allele frequencies using sequence-specific oligonucleotide Prob (SSOP) method. Serum total antioxidant capacity (TAC) levels were measured and compared between vitiligo patients and controls. RESULTS: HLA-A*02 allele frequency was increased (OR = 1.6, CI = 1.12-2.24, P = .009), HLA-A*11 (OR = 0.46, CI = 0.32-0.91, P = .019) and HLA-DRB1*01 (OR = 0.39, CI = 0.16-0.92, P = .029) frequencies were decreased in vitiligo patients. HLA-A*02 allele especially increased the risk of late onset (Vitiligo onset >30 years of age) vitiligo (OR:3.67, 95% CI: 1.63-8.26, P = .002). Serum TAC levels were similar between vitiligo patients and healthy controls but TAC levels were significantly lower in patients who did not have an HLA-DRB1*01 allele (1.52 vs 1.61, P = .033). CONCLUSION: Our study showed that HLA-A*02 increases, HLA-A*11 and HLA-DRB1*01 decreases vitiligo susceptibility in Turkish patients as well as a possible relationship between HLA and TAC.

INTRODUCTION: Galectin-3 is a ß-galactoside-binding lectin associated with cellular proliferation, inflammation and angiogenesis, which are the major characteristics of psoriatic skin. OBJECTIVES: To investigate serum galectin-3 levels in psoriasis patients compared with healthy controls and to study its relationship with disease characteristics. METHODS: Seventy-eight patients diagnosed with psoriasis and 78 age- and sex-matched healthy volunteers were included in the study. Serum galectin-3, IL-17, IL-6 and TNF-α levels were measured using Enzyme-linked immunosorbent assay (ELISA). RESULTS: Serum Galectin-3, IL-17, IL-6 and TNF-α levels were significantly higher in psoriasis patients compared with control group (P < .001, P = .003, P < .001 and P < .001, respectively). A cut-off value of 10 ng/mL for galectin-3 was set after receiver operating characteristic analysis. A serum galectin-3 level >10 ng/mL increased the risk of psoriasis by 14.5 times (95% CI: 6.6-32.3, P < .001) and a serum galectin-3 level >10 ng/mL predicted psoriasis with 83.3% sensitivity and 74.3% specificity. No statistically significant association was observed between serum galectin-3 concentrations and disease characteristics including disease severity, presence of psoriatic arthritis, nail involvement and psoriatic comorbidity. No statistically significant correlation was observed between serum galectin-3 level and serum IL-17, IL-6 and TNF-α levels (all three P values > .05). CONCLUSIONS: Elevated serum galectin-3 levels in psoriasis patients may indicate a possible role of galectin-3 in pathogenesis of psoriasis.

The 14 authors of the first review article on hidradenitis suppurativa (HS) pathogenesis published 2008 in EXPERIMENTAL DERMATOLOGY cumulating from the 1st International Hidradenitis Suppurativa Research Symposium held March 30-April 2, 2006 in Dessau, Germany with 33 participants were prophetic when they wrote "Hopefully, this heralds a welcome new tradition: to get to the molecular heart of HS pathogenesis, which can only be achieved by a renaissance of solid basic HS research, as the key to developing more effective HS therapy." (Kurzen et al. What causes hidradenitis suppurativa? Exp Dermatol 2008;17:455). Fifteen years later, there is no doubt that the desired renaissance of solid basic HS research is progressing with rapid steps and that HS has developed deep roots among inflammatory diseases in Dermatology and beyond, recognized as "the only inflammatory skin disease than can be healed". This anniversary article of 43 research-performing authors from all around the globe in the official journal of the European Hidradenitis Suppurativa Foundation e.V. (EHSF e.V.) and the Hidradenitis Suppurativa Foundation, Inc (HSF USA) summarizes the evidence of the intense HS clinical and experimental research during the last 15 years in all aspects of the disease and provides information of the developments to come in the near future.

BACKGROUND: Rosacea is a chronic disease that is characterized by facial skin inflammation and vascular abnormality. Vascular endothelial growth factor (VEGF) is a potent mediator of vascular permeability and inflammation that might play a role in the pathogenesis of rosacea. OBJECTIVE: This study aimed to determine the association between VEGF gene polymorphisms and rosacea. METHODS: A case-control study design was used to compare 100 patients with rosacea and 100 age- and gender-matched control subjects in terms of VEGF polymorphisms based on polymerase chain reaction and the serum level of VEGF and VEGF receptors based on enzyme-linked immunosorbent assay. RESULTS: Heterozygous and homozygous +405C/G polymorphism of the VEGF gene was observed to increase the risk of rosacea 1.7-fold (95% confidence interval 1.2-4.2) and 2.3-fold (95% confidence interval 1.2-4.2), respectively. There was a significant positive correlation between the severity of rosacea and +405C/G polymorphism of the VEGF gene in patients with erythematotelangiectatic rosacea. LIMITATIONS: Serum VEGF and VEGF receptor levels were measured in the limited number of patients. CONCLUSION: The present findings indicate that +405C/G polymorphism of the VEGF gene increases the risk of rosacea.

Background/aim: Erythema nodosum (EN) is an inflammatory disorder of subcutaneous tissue. Although etiopathogenesis of the disease is unknown, many predisposing factors such as infections, systemic disease, and drugs have been identified. Neutrophil to lymphocyte ratio (NLR) has been shown to be a novel inflammatory marker in many dermatological diseases. The aim of our study is to investigate NLR in EN patients and evaluate its relation to the underlying cause of the disease. Materials and methods: Between 2014 and 2018, clinical and laboratory data of 395 patients diagnosed with EN and 395 controls were extracted from patient files. EN patients were grouped as idiopathic EN and secondary EN (EN with an identified underlying cause). Clinical and laboratory characteristics of the two groups were compared Results: NLR was elevated in EN patients compared to controls (median of 2.38 vs. 1.55, P < 0.001). Among EN patients, NLR was also elevated in patients with secondary EN. In multivariate logistic regression model NLR (> 2.11), RDW-CV (> 13.65), and CRP (> 5.5) were identified as risk factors for secondary EN (relative risks were 17.16, 2.69, and 2, respectively). Conclusion: Elevated NLR (> 2.11) may be used as a parameter to discriminate secondary EN from idiopathic EN.

INTRODUCTION: Morphea localized scleroderma (LS) is a rare skin disease with unknown pathogenesis, which causes sclerosis of the dermis and subcutaneous tissue. OBJECTIVES: It was aimed to compare the characteristics of patients with pediatric and adult-onset morphea. METHODS: A retrospective analysis was performed on the records of 183 adult morphea patients. The demographics, clinical and laboratory characteristics, and treatment options of the patients were recorded. Adult patients with morphea over the age of 18 were divided into two groups according to the age of onset and compared. RESULTS: Twenty-two percent (N = 41) of the patients had pediatric-onset morphea (POLS) and 77.6% (n=142) had adult-onset morphea (AOLS). While POLS had a higher head-neck involvement, AOLS had a higher breast involvement (P < 0.001 and P = 0.043). Patients with linear morphea were younger, and more frequently had at least one laboratory anomaly (P = 0.016 versus 0.024). Anti-dsDNA positivity and low hemoglobin (Hb) were observed more frequently in patients with breast involvement. Patients with inguinal involvement, on the other hand, had lower Hb and a higher rate of diabetes, and those patients were older (P = 0.042, 0.040, and 0.012, respectively). CONCLUSIONS: Clinical characteristics and accompanying laboratory anomalies of the patients with morphea depend on the age of onset, involvement areas and the types of morphea, having such data readily available should guide the holistic approach for, and the monitoring process of, the disease.
RESUMO
Melasma is a common acquired hyperpigmentation disorder that affects mostly women and individuals with darker skin types. Oxidative stress may play a role in the pathogenesis of melasma. Dynamic thiol/disulfide homeostasis is one of the most important indicators of oxidative stress. This study aimed to investigate the presence of oxidative stress in patients with melasma by evaluating thiol/disulfide homeostasis. Sixty-seven patients with melasma and 41 healthy age- and sex-matched controls were included in the study. Disease severity was evaluated using the modified melasma area and severity index (mMASI). Thiol/disulfide homeostasis parameters of the melasma and control groups were measured using a novel, fully automated spectrophotometric method. Our data indicated the presence of oxidative stress in melasma, which may be correlated with disease severity. Because research on the presence of oxidative stress in melasma is limited, further studies are needed to support these conclusions.

INTRODUCTION: Vitiligo is a chronic skin disorder in which immune dysregulation has been reported as one of the major etiopathological factors. Interleukin-12 (IL-12), IL-23 and IL-27 of IL-12 cytokine family were identified as critical cytokines in the pathogenesis of many autoimmune and inflammatory skin diseases including vitiligo. IL-35 is one of the newest member of IL-12 cytokine family. OBJECTIVES: The purpose of our study was to examine serum IL-35 levels in addition to serum IL-12, IL-23, IL-27 levels in the vitiligo patients and control group, and to investigate the relationship of these cytokines with the characteristics of vitiligo. METHODS: Serum IL-12, IL-23, IL-27 and IL-35 levels of 87 vitiligo patients and 70 healthy volunteers were analyzed using the enzyme-linked immunosorbent assay (ELISA). We compared the IL-12 cytokine family levels in the patient and control groups, and investigated the relationship of these levels with the characteristics of vitiligo. RESULTS: Patients had higher levels of IL-12 (31.2 versus 20.1, P < 0.001) and IL-35 (9.6 versus 8.1, P = 0.031). Patient and control groups had similar levels of IL-23 (P = 0.78) but were correlated with the Vitiligo Area Scoring Index (VASI) (P = 0.022, r = 0.35). Patients had lower levels of IL-27 (207.6 versus 258.7, P < 0.001). In addition, the levels of serum IL-27 were correlated negatively with the Vitiligo Disease Activity (VIDA), and positively with disease duration (P = 0.007, r = 0.30). CONCLUSIONS: Differences of serum levels between Vitiligo patients and healthy controls, significant relationships with the characteristics of vitiligo suggest that the IL-12 cytokine family may play a role in the pathogenesis of vitiligo.
RESUMO
INTRODUCTION: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are life-threatening acute mucocutaneous disorders usually triggered by drugs. In this study, we aimed to evaluate the factors affecting mortality in patients with SJS-TEN. METHODS: Our study is a retrospective cohort study, analyzing data collected from a total of 12 tertiary care centers between April 2012 and April 2022. RESULTS: The study included 59 males and 107 females, a total of 166 patients, with an average age of 50.91 ± 21.25 years. Disease classification was TEN in 50% of cases, SJS in 33.1%, and SJS-TEN overlap in 16.9%. The average SCORTEN within the first 24 h was 2.44 ± 1.42. Supportive care was provided to 99.4% of patients. The most commonly used systemic immunomodulatory treatments were systemic steroids (84.3%), IVIG (intravenous immunoglobulin) (49.3%), and cyclosporine (38.6%). Plasmapheresis was administered to five patients. While 66.3% of patients were discharged, 24.1% resulted in exitus. Our comparative analysis of survivors and deceased patients found no effect of systemic steroids, IVIG, and cyclosporine treatments on mortality. Univariate analysis revealed that the SCORTEN scores on days 1 and 3 as well as the rates of detachment at the onset and during follow-up were significantly higher in deceased patients compared to survivors. The rates of fever, positive blood cultures, and systemic antibiotic use were higher in deceased patients compared to survivors. The presence of comorbidities, diabetes, and malignancy were significantly more common in deceased patients. Multivariate regression analysis indicated that over SCORTEN 2, the mortality risk exponentially rose with each SCORTEN increment, culminating in an 84-fold increase in mortality at SCORTEN 5-6 (odds ratio [95% confidence interval]: 13.902-507.537, p < 0.001) compared to SCORTEN 0-1. Additionally, the utilization of plasmapheresis was associated with a 22-fold increase in mortality (odds ratio [95% confidence interval]: 1.96-247.2, p = 0.012). CONCLUSION: Our study found that a high SCORTEN score within the first 24 h and the use of plasmapheresis were related to increased mortality, while systemic steroids, IVIG, and cyclosporine treatments had no impact on mortality. We believe that data gathered from one of the most comprehensive studies which we conducted on SJS-TEN will enrich the literature, although additional research is warranted.
RESUMO
BACKGROUND: Pyoderma Gangrenosum (PG) is a chronic disease characterized by recalcitrant skin ulcers. OBJECTIVE: We aimed to evaluate the demographic, clinical characteristics, treatments and factors affecting the treatment responses of patients with PG. METHODS: We performed a multicenter study of 12 tertiary care centers. We analyzed the data of the patients who were followed up with a diagnosis of PG between the years 2012â2022 retrospectively. RESULTS: We included a total of 239 patients of whom 143 were female and 96 were male, with an average age of 54.2⯱â¯17.4 years. The most common treatment was systemic steroids (nâ¯=â¯181, 75.7%). Among these patients, 50.8% (nâ¯=â¯92) used systemic steroids as the sole systemic agent, while 49.2% (nâ¯=â¯89) used at least one adjuvant immunosuppressive agent. The independent factors determined in regression analysis to influence response to systemic steroids positively were disease onset age ≥ 30-years, negative pathergy, absence of leukocytosis, negative wound culture, presence of a single lesion, and absence of upper extremity involvement. Biological agents were used in 18.4% (nâ¯=â¯44) of the patients in the present study. We also analyzed pathergy positive PG and early onset (onset age < 30) PG separately due to their distinct clinical features which were revealed during statistical analysis. STUDY LIMITATIONS: Retrospective nature of the present study. CONCLUSIONS: Analyses of the factors influencing treatment responses are addressed in this study. Also, we concluded that investigation for accompanying autoinflammatory diseases of pathergy positive PG and early onset PG is necessary and the patients in these two groups are more resistant to treatment, necessitating more complicated treatments.
RESUMO
Methotrexate (MTX) is commonly used as first-line systemic treatment agent in psoriasis. We aimed to evaluate the clinical characteristics and treatment responses of patients with psoriasis undergoing MTX monotherapy. Data from adult patients with plaque psoriasis who received MTX monotherapy for at least 3 months between April 2012 and April 2022 were retrospectively evaluated in 19 tertiary care centers. Our study included 722 female and 799 male patients, a total of 1521 participants. The average age of the patients was 44.3 ± 15.5 years. Mode of treatment was oral in 20.4% of patients while in 79.4% it was subcutaneous. The median treatment duration was 8 months (IQR = 5-15). The median weekly dose was 15 mg (IQR = 11-15). 1448 (95.2%) patients were taking folic acid supplementation. At week 12, 16.3% of the patients achieved PASI (Psoriasis Area and Severity Index) 90 response while at week 24, 37.3% achieved it. Logistic regression analysis for week 12 identified the following independent factors affecting PASI 90 achievement positively: median weekly MTX dose ≤ 15 mg (P = 0.011), subcutaneous administration (P = 0.005), no prior systemic treatment (< 0.001) and folic acid use (0.021). In logistic regression analysis for week 24; median weekly MTX dose ≤ 15 mg (P = 0.001), baseline PASI ≥ 10 (P < 0.001), no prior systemic treatment (P < 0.004), folic acid use (P = 0.001) and absence of comorbidities (P = 0.009) were determined as independent factors affecting the achievement of PASI 90. Adverse effects were observed in 38.8% of the patients, with nausea/vomiting (23.9%) and transaminase elevation (13%) being the most common. The most common reasons for interruptions (15.3%) and discontinuations (27.1%) of the treatment were patient related individual factors. The use of MTX as the first systemic treatment agent, at doses ≤ 15 mg/week and concurrent folic acid application are positive predictive factors for achieving the target PASI response both at weeks 12 and 24. In our study, which is one of the most comprehensive studies on MTX treatment in psoriasis, we observed that MTX is an effective and safe treatment option.

OBJECTIVE: Seborrheic dermatitis is a common papulosquamous skin disease with unknown pathogenesis. The aim of our study was to determine the serum level of 25-hydroxy vitamin D in patients with seborrheic dermatitis SD. METHODS: A total of 53 patients and 60 healthy controls were included in the study. Serum vitamin D, calcium, phosphorus, and parathormone levels were measured in the patient and control groups, and a comparison was made between the two groups regarding these parameters. RESULTS: Severe vitamin D deficiency was more frequent among patients with seborrheic dermatitisSD compared to controls (52.8 vs. 25.8%, p=0.003). In patients with severe vitamin D deficiency, seborrheic dermatitis SD was detected more frequently at an early age (p=0048) and in women (p=0.015). No correlation was found between the seborrheic dermatitis skin involvement site and vitamin D level. CONCLUSION: The fact that vitamin D levels decreased in patients with seborrheic dermatitis SD and patients with severe vitamin D deficiency develop seborrheic dermatitis SD earlier suggests that the low levels of vitamin D are related to seborrheic dermatitis.

Background: Vitiligo, a multifactorial, depigmented skin disease, is characterised by selective loss of functional melanocytes leading to pigment reduction in the affected areas of the skin. Aim: We aimed to examine thiol-disulphide homeostasis, IMA, copper, zinc, selenium, vitamin A and vitamin C levels in vitiligo patients. Materials and Methods: The study included 83 vitiligo patients and 72 healthy controls. Copper, zinc, and selenium levels were measured by atomic absorption spectrophotometer; vitamin A and E levels were measured by high-performance liquid chromatography. Ischemia-modified albumin and native/total thiol levels were measured by colourimetric method. Results: Serum native and total thiol levels were significantly lower in vitiligo patients (P < 0.001, for all). Zn levels were significantly higher in vitiligo patients than in the control group (P = 0.004). There was no statistical difference in terms of Cu, Se, vitamin A and vitamin E levels. Conclusions: All thiol-disulphide homeostasis parameters (the most important antioxidant-oxidant system in circulation), trace elements, and vitamins together were evaluated in the present study in vitiligo patients. It can be concluded that vitiligo patients have increased oxidative stress status, and also the increase in the dissemination of the disease also increases the oxidative stress in the body.
RESUMO
INTRODUCTION: Psoriasis is an immune-mediated, chronic and inflammatory disease whose pathogenesis is affected by the interactions of several immune cells and cytokines. PD-1 is an inhibitor receptor that is expressed to a large extent in T lymphocytes and responsible for regulating autoimmunity and self-tolerance. OBJECTIVES: In this study, we aimed to investigate the expression of PD-1/PD-L molecules in the lesioned skins of psoriasis patients. METHODS: The study included 30 psoriasis patients, and 15 healthy volunteers as the control group. Anti PD-1 and PD-L1 antibodies were applied to the skin biopsy samples that were collected from the patient and control groups. Cytoplasmic and membranous staining of PD-1 and PD-L1 were considered positive. The number of stained immune cells that was examined for each case. RESULTS: The percentage of the tissues with high PD-1 (+) and PDL-1 (+) immune cell counts were significantly higher in the psoriasis patients compared to healthy controls (P values = 0.004 and 0.002, respectively). A negative and statistically significant correlation was detected between PDL-1(+) immune cell numbers and PASI scores (P = 0.033, r=-0.57). CONCLUSIONS: In the lesioned skin samples of psoriasis patients, the PD-1 and PD-L1 expressions were significantly higher in immune cells than that in the skin samples of the healthy controls. This study was the first investigation of the expression of PD-1/PD-L molecules in the immune cells in found the lesioned skins of psoriasis patients.
RESUMO
BACKGROUND: Seborrheic dermatitis (SD) is a common, chronic inflammatory disease with relapses and remissions. OBJECTIVES: So we planned to investigate the relationship between SD and metabolic syndrome (Mets). METHODS: 54 patients over 18 years of age without known diabetes mellitus, hypertension, coronary artery disease who were clinically diagnosed with SD in our clinic and 47 healthy controls were included in the study. Body mass index (BMI) was calculated of all participants. Complete blood count, fasting blood sugar (FBG), triglyceride (TG), total cholesterol, high-density lipoprotein (HDL), and low-density lipoprotein (LDL) were examined. The relationship between the presence of MetS, disease severity, and duration was investigated. RESULTS: Average age of patients was 35.4 (sd: 12). Average age of controls was 32.9 (sd: 10.7). MetS was detected in 35.2% (n = 19) of the patient group and 10.6% (n = 5) of the control group. The presence of MetS was higher in SD patients than in the control group (p = 0.004). The rate of people with high TG was significantly higher in the SD group than the controls (p = 0.015). HDL level was significantly lower in the patient group (p = 0.050). Systolic and diastolic blood pressure were high in patients (p = 0.016, p = 0.029). CONCLUSIONS: Seborrheic dermatitis should be considered as a MetS marker and the presence of MetS should be examined in this group of patients. This can be helpful for the early diagnosis of a systemic disease complex with numerous complications. Also, treatment of MetS can also improve SD lesions.

BACKGROUND: Venous hypertension causes many different cutaneous findings such as varicosities, telangiectasia, edema, and pigmentation, dermatitis, and venous ulcers on the skin. OBJECTIVE: This study aims to investigate the cutaneous signs and symptoms of chronic venous insufficiency (CVI) and to examine their contribution to early diagnosis. METHODS: A total of 150 patients were included in the study who applied to the dermatology outpatient clinic and were diagnosed with skin disease related to CVI or had skin findings. Patient's age, gender, complaints, occupation, additional diseases, drug usage, history of prolonged standing and travel, smoking habit, number of pregnancies, history of varicose veins in the family, dermatological diagnosis/findings, and venous Doppler ultrasonography reports were examined retrospectively. RESULTS: 56% of patients were women. Mean age was 56.69 ± 13.6 years. Overall, 82.7% of total patients had at least one skin finding. The most frequent skin findings except varicose veins were insufficiency dermatitis accounted for 32.7% of patients, telangiectasia, and pigmentation which were comprised 25.3%, 19.3% of the total number of patients respectively. In addition to this, 48.7% of patients had itching problems and 32.7% had pain. Moreover, 46% of patients presented superficial vein insufficiency, while 8.7% had deep vein insufficiency. For 47.3% of patients, vein diameter dilation was observed and 11.3% suffered from perforating vein insufficiency. In terms of Clinical-Etiologic-Anatomic-Pathophysiologic (CEAP) classification, scores of 52% of the patients were C3 and lower, while scores of 48% of total patients were C4a and higher. CONCLUSIONS: Early diagnosis and treatment of chronic venous insufficiency could prevent further chronic processes such as venous ulceration which is an advanced CVI finding. Thus, assessing the early skin findings might be important to identify the underlying venous insufficiency disease.

BACKGROUND: Androgenetic alopecia (AGA) is the most common cause of hair loss in men. In addition to genetic and hormonal factors, oxidative stress (OS) is suggested as a factor in the etiology. AIM: In this study, we aimed to investigate the presence of OS due to thiol disulfide balance deterioration in male patients with AGA. MATERIALS AND METHODS: A total of 45 male AGA patients and 42 healthy male controls were included in the study. Native thiol, disulfide, and total thiol levels were assessed through automated spectrophotometry. The relationship between total protein, albumin, native thiol, disulfide, and total thiol levels in addition to demographic and clinical characteristics of the patients were examined. RESULTS: The mean age of the patients was 32.6 ± 10 years, and the median AGA duration in the patients was 3 years. There was no statistically significant difference in terms of native thiol, disulfide, total thiol levels, disulfide/total thiol, disulfide/native thiol, and native thiol/total thiol ratios between AGA patients and controls. Native thiol and total thiol levels negatively correlated with age and AGA duration, while disulfide levels only correlated with age.Albumin and native thiol levels were significantly lower in patients with low vitamin D levels (p = 0.040 and p = 0.021, respectively); however, total thiol and native thiol/total thiol ratio values were significantly higher. CONCLUSION: According to this study, thiol disulfide homeostasis is in balance in male patients with AGA. In patients with emotional stress and vitamin D deficiency, the balance appears to be shifted in favor of oxidative stress.
