J Cosmet Dermatol 2023; 22:2579-2583. [PMID: 37017934 DOI: 10.1111/jocd.15754] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Revised: 02/03/2023] [Accepted: 03/21/2023] [Indexed: 04/06/2023]
Abstract
BACKGROUND Alopecia areata (AA) is an immune-mediated nonscarring hair loss disorder with multiple subtypes, including alopecia universalis (AU). Previous studies have shown a link between serum lipid profile and alopecia. We aimed to investigate the frequency of fatty liver in patients with AU and patchy alopecia areata (PAA) compared to a control group. METHODS This case-control study included patients with AU and PAA referred to a dermatology clinic from September 23, 2019 to September 23, 2020. A group of individuals without hair loss disorders attending the same clinic were selected as controls. Participants' general information, including age, sex, weight, height, and waist circumference (WC), was recorded. Body mass index (BMI) was calculated for all participants. Also, hyperlipidemia and statin use were noted and liver enzymes were evaluated. For AU and PAA patients, disease duration and the Severity of Alopecia Tool (SALT) score were also recorded. Then, all subjects underwent ultrasound to assess fatty liver and its grade. RESULTS Overall, 32 patients were included in each group. All three groups were comparable in age, sex, weight, height, BMI, WC, hyperlipidemia, abnormal liver enzymes, and statin use. Disease duration and SALT score were significantly higher in the AU than in the PAA group (p = 0.009 and p < 0.001, respectively). The frequency of fatty liver was the highest in AU patients (40.6%), followed by 34.4% in PAA patients, and 21.9% in controls (p = 0.263). This was also the case for grade-1 fatty liver, while grade-2 was more common in PAA patients, and grade-3 was only observed in one patient from the AU group (p = 0.496). CONCLUSIONS Fatty liver was more frequent in AU and PAA patients than controls, without statistically significant differences. There might be an association between fatty liver and AA, particularly the AU subtype.

Abstract
Alopecia areata (AA) is an inflammatory autoimmune disease characterized by non-scarring hair loss on the scalp or any other part of the hair-bearing skin. While the collapse of the immune privilege is considered as one of the most accepted theories accounting for AA, the exact pathogenesis of this disease remains unclear by now. Other factors, such as genetic predisposition, allergies, microbiota, and psychological stress, also play an important role in the occurrence and development of AA. Oxidative stress (OS), an unbalance between the oxidation and antioxidant defense systems, is believed to be associated with AA and may trigger the collapse of hair follicle-immune privilege. In this review, we examine the evidence of oxidative stress in AA patients, as well as the relationship between the pathogenesis of AA and OS. In the future, antioxidants may play a new role as a supplementary therapy for AA.

Abstract
Purpose Oxidative stress (OS) plays a critical role in the onset and progression of macro and microvascular complications of diabetes mellitus (DM). Ischemia-modified albumin (IMA) is a novel and simple test for evaluating OS. In the present study, we reviewed the available information on the alteration of circulating IMA in DM and its possible prognostic and diagnostic value in DM-related complications. Methods Relevant studies regarding IMA alteration in DM published until May 30, 2022 were extracted from Google Scholar, PubMed, Scopus, and Science Direct databases. The following key words were used: IMA, DM, diabetes complications, retinopathy, nephropathy, diabetic foot, and vascular complications. Results This review revealed increased circulating IMA levels in the patients with type 1, type 2, and gestational DM. Furthermore, IMA showed a close relationship with the severity of DM complications including hyperglycemia, dyslipidemia, diabetic retinopathy, diabetic nephropathy, peripheral arterial disease, and diabetic foot ulcer. However, lack of assay standardization and low specificity are major obstacles to the use of IMA as a promising biomarker. Conclusion IMA levels are associated with DM complications and can be applied as a practical test for evaluating the risk and predicting the severity of DM complications.

Abstract
Context Alopecia areata (AA) is the most common cause of inflammatory, nonscarring hair loss, involving hair-bearing areas of the body. The etiology of AA still remains uncertain; however, genetic, environmental, and autoimmunity play a role. Newer theories such as oxidative theory, HPA axis activation, and finally, the role of increased inflammatory cytokines such as interleukin 1 (IL1), tumor necrosis factor-alpha, interferon-gamma, IL-2 IL-4, and MIF are suggested to contribute to both AA and metabolic syndrome (MS). Aims Assessment of the degree of association of MS (NCEP ATP III criteria) in clinically diagnosed cases of AA and compare to that of controls. Materials and Methods Similar age/sex-matched AA patients and controls (106 in each group) were taken. Anthropometric measurements, blood-sugar estimation, lipid-profile estimation in venous blood sample, and blood-pressure measurement were done. Results Prevalence of MS was almost similar among cases of AA 9/106 (8.47%) as well as healthy controls 8/106 (7.54%), and the difference was not statistically significant (P = 1). Among all components of MS, waist circumference (WC) (central obesity) was the most common parameter (100% cases). In controls, high systolic blood pressure (SBP) was the most common parameter (77.78% controls). AA is associated with a higher level of SBP, diastolic blood pressure (DBP), WC although nonsignificant, and low level of high-density lipoprotein cholesterol which was the only significant association. Conclusion Insignificant correlation between occurrence of MS and evidence of insulin resistance (IR) in AA was observed in this study population. However, some of the observations in the present study may raise awareness in susceptible individuals that lifestyle changes and regular screening in AA can reduce the risk of cardiovascular diseases and other co-existing autoimmune inflammatory condition-IR, dyslipidemia, and hypertension.

Abstract
Alopecia areata (AA) is a dermatological condition characterized by non-scarring hair loss. Exact etiopathogenesis of AA is still unknown although it is known that several factors contribute to the collapse of the hair-follicle (HF)-immune-privileged (IP) site. Oxidative stress (OS) plays an important role in skin diseases. The aim of this review was to clarify the role of OS in AA pathogenesis and diagnosis, and to discuss potential treatment options. Oxidative-stress markers are altered in serum and skin samples of patients with AA, confirming a general pro-oxidative status in patients with AA. OS induces MHC class I chain-related A (MICA) expression in HF keratinocytes that activates the receptor NKG2D, expressed in NK cells and CD8+ T cytotoxic cells leading to destabilization of the HF immune-privileged site through the production of IFN-γ that stimulates JAK1 and JAK2 pathways. OS also activates the KEAP1-NRF2 pathway, an antioxidant system that contributes to skin homeostasis. In addition, a decrease of ATG5 and LC3B in the hair matrix and an increase in p62 levels indicates a reduction of intrafollicular autophagy during the evolution of AA. Potential biomarkers of OS in AA could be: malondialdehyde (MDA), advanced glycation end-products (AGEs), and ischemic-modified albumin (IMA). JAK inhibitors are the new frontier in treatment of AA and the use of nutraceuticals that modulate the OS balance, in combination with standard treatments, represent promising therapeutic tools.

Abstract
INTRODUCTION OBJECTIVE: To investigate the role of ischemia-modified albumin (IMA) and IMA/albumin levels in patients with AA. METHODS The present prospective crossectional study includes patients ≥18 who were admitted to the Dermatology and Venerology Department of Hitit University Hospital between April 1, 2021, and September 30, 2021. 70 patients participated in the study (n=34 for the study group and n=36 for the control group). Demographic features, clinical characteristics, IMA, and IMA/albumin levels were compared between the groups. The study group was divided into subgroups based on the number of patches, disease duration, and the number of disease attacks. IMA and IMA/albumin levels were compared between each subgroup. RESULTS The study and control groups were similar with regard to demographic features and clinical characteristics. Significant differences were observed between the mean IMA and IMA/albumin ratio (p=0.004 and 0.012, respectively). The study subgroups were comparable in the number of patches, disease duration, and number of disease attacks. CONCLUSION Although oxidative stress is an important component in the etiology of AA, IMA and IMA/albumin may not be useful in the prediction of disease severity in patients with AA.

Abstract
Lipocalin-2 and visfatin are proinflammatory adipokines involved in the regulation of glucose homeostasis. Their role has been described in numerous inflammatory skin diseases such as atopic dermatitis and psoriasis. Recently, an increased prevalence of metabolic abnormalities has been reported in patients with alopecia areata. The aim of the study is to determine the serum levels of lipocalin-2 and visfatin in patients with alopecia areata in comparison with healthy controls. Moreover, the serum levels of total cholesterol, low-density lipoprotein cholesterol (LDL-cholesterol), high-density lipoprotein cholesterol (HDL-cholesterol), triglycerides, fasting glucose, insulin, c-peptide, and homeostasis model assessment for insulin resistance (HOMA-IR) were evaluated. Fifty-two patients with alopecia areata and 17 control subjects were enrolled in the study. The serum levels of lipocalin-2 [mean ± standard deviation, SD: 224.55 ± 53.58 ng/ml vs. 188.64 ± 44.75, p = 0.01], insulin [median (interquartile range, IQR): 6.85 (4.7–9.8) μIU/ml vs. 4.5 (3.5–6.6), p<0.05], c-peptide [median (IQR): 1.63 (1.23–2.36) ng/ml vs. 1.37 (1.1–1.58), p<0.05)], and HOMA-IR [median (IQR): 1.44 (0.98–2.15) vs. 0.92 (0.79–1.44), p<0.05) were significantly higher in patients with alopecia areata compared to the controls. The serum concentration of insulin and HOMA-IR correlated with the number of hair loss episodes (r = 0.300, p<0.05 and r = 0.322, p<0.05, respectively). Moreover, a positive correlation occurred between insulin, HOMA-IR, c-peptide and BMI (r = 0.436, p <0.05; r = 0.384, p<0.05 and r = 0.450, p<0.05, respectively). In conclusion, lipocalin-2 and insulin may serve as biomarkers for alopecia areata. Further studies are needed to evaluate the role of insulin as a prognostic factor in alopecia areata.

Abstract
There is growing evidence that oxidative stress is involved in the pathogenesis of numerous conditions, including dermatological diseases. Various markers are available to assess oxidative stress, but none of these can be considered the ideal marker. Recent studies have shown that ischemia-modified albumin (IMA) is not only an indicator of ischemia, but also a marker of oxidative stress. We have conducted a narrative review to evaluate the role of IMA in dermatological diseases. We have identified 24 original articles that evaluated IMA in skin disorders (psoriasis, acne vulgaris, hidradenitis suppurativa, urticaria, vitiligo and Behcet’s disease) and hair disorders (alopecia areata, androgenetic alopecia and telogen effluvium). The results of the studies analyzed reveal that IMA may be considered a new marker of oxidative stress in dermatological diseases and offer new insights into the pathogenesis of these disorders and the theoretical basis for the development of new, effective, targeted therapies. To the best of our knowledge, this is the first review that gathers up data on the role of IMA in dermatological diseases.

Abstract
Alopecia areata is an autoimmune, inflammatory form of non-scarring hair loss that may affect any hair-bearing area. Recently, an increased risk of cardiovascular disorders has been described in patients with alopecia areata. The aim of the study was to evaluate the serum concentrations of proinflammatory proteins associated with atherosclerosis (chemokine C-C motif ligand 4; CCL4, chemokine C-C motif ligand 7, CCL7; and sortilin, SORT1), and cardiovascular risk (myeloperoxidase, MPO; interleukin 1 receptor-like 1, IL1RL1; and growth differentiation factor 15, GDF15) in patients with alopecia areata without symptoms or prior cardiovascular disease in comparison with healthy controls. Sixty otherwise healthy patients with alopecia areata and twenty control subjects matched for age, gender, and body mass index (BMI) were enrolled in the study. No significant differences in the serum levels of MPO, IL1RL1, CCL4, CCL7, SORT1, and GDF15 were detected between patients with alopecia areata and healthy controls. A positive correlation was found between the serum concentration of CCL7 and the severity of alopecia areata (r = 0.281, p = 0.03), while GDF15 correlated with age at the disease onset (r = 0.509, p < 0.0001). The results of the present study suggest that the severity of alopecia areata may be associated with an increased risk of atherosclerosis.

Abstract
BACKGROUND Growing evidence has revealed abnormalities in the retinal structures of patients with alopecia areata (AA). However, the relationship between AA and retinopathy remains unclear. OBJECTIVE To investigate the association between AA and retinal diseases. METHODS The study participants were recruited from the National Health Insurance Research Database in Taiwan. We included 9909 patients with AA and 99,090 matched controls to assess the risk of retinal diseases. A Cox regression model was used for all analyses. RESULTS Compared with the controls, patients with AA had an adjusted hazard ratio (aHR) of 3.10 (95% confidence interval [CI] 2.26-4.26) for retinal diseases. With respect to individual retinal diseases, Patients with AA had significantly higher risks of developing retinal detachment (aHR 3.98; 95% CI 2.00-7.95), retinal vascular occlusion (aHR 2.45; 95% CI 1.22-4.92), and retinopathy (aHR 3.24; 95% CI 2.19-4.81) than controls. LIMITATIONS This was a retrospective cohort study. Meanwhile, almost all the participating individuals were residents of Taiwan; therefore, the validity of our findings in other demographics remains unclear. CONCLUSION Patients with AA had a significantly higher risk of retinal disease than controls. Further studies are needed to clarify the pathophysiology of AA and retinal diseases.

Abstract
Importance Alopecia areata (AA) is a common autoimmune disease presenting as nonscarring hair loss. Although AA can be associated with other autoimmune comorbidities or atopic diseases, little is known about the risk of cardiovascular diseases in patients with AA. Objective To investigate the risk of acute myocardial infarction (AMI) and cardiovascular risk profiles (CVRPs) in patients with AA via a large-scale epidemiologic study. Design, Setting, and Participants This was a retrospective cohort study using data from the Korean National Health Insurance claims database, including data from the National Health Screening Program. Patients aged 30 to 89 years who were newly diagnosed with AA between January 1, 2006, and December 31, 2017, and controls without AA matched by age and sex were enrolled. Data were analyzed between July 2018 and August 2019. Exposures Presence of AA. Main Outcomes and Measures The CVRPs and incidence rates of AMI were assessed in participants with and without AA. The stratified Cox regression hazard model was used to estimate the relative hazards over time. Results A total of 228 886 patients with AA, ranging in age from 30 to 89 years (mean [SE] age, 44.37 [0.005] years; 127 564 [55.7%] men) and 4 577 720 matched controls without AA were identified. Patients with AA tended to have slightly better CVRPs than controls in all items except smoking status before and after the diagnosis (participants with normal systolic blood pressure who were nonsmokers: 44.6% vs 42.7% and 57.8% vs 61.6% in patients with AA vs controls before and after the diagnosis, respectively). In the early phase of observation, the cumulative incidence of AMI in patients with AA was lower than that in controls (incidence rate ratio of AMI in patients with AA compared with that in controls, 0.52 [95% CI, 0.42-0.65] between 2-4 years); however, during the later phase of the 12-year follow-up period, it increased exponentially and was greater than in the control group (incidence rate ratio, 2.06 [95% CI, 1.71-2.45] between 8-10 years). Similarly, after adjusting for CVRPs, the risk of developing AMI was lower in patients with AA than in controls at the beginning of the observation period (adjusted hazard ratio (HR), 0.17 [95% CI, 0.12-0.25] between 0-2 years); however, by 8 years postdiagnosis, the risk was higher in those with AA (adjusted HR, 1.37 [95% CI, 1.11-1.70] between 8-10 years), and it increased thereafter (adjusted HR, 4.51 [95% CI, 3.65-5.58] between 10-12 years). Conclusions and Relevance In patients with AA, there was a significantly increased risk of AMI over time during the 12-year follow-up period independent of CVRPs. Close long-term monitoring of cardiovascular health in patients with AA might be appropriate.

Abstract
Adipokines are the primary mediators of adipose tissue-induced and regulated systemic inflammatory diseases; however, recent findings revealed that serum levels of various adipokines correlate also with the onset and the severity of dermatological diseases. Importantly, further data confirmed that the skin serves not only as a target for adipokine signaling, but may serve as a source too. In this review, we aim to provide a complex overview on how adipokines may integrate into the (patho) physiological conditions of the skin by introducing the cell types, such as keratinocytes, fibroblasts, and sebocytes, which are known to produce adipokines as well as the signals that target them. Moreover, we discuss data from in vivo and in vitro murine and human studies as well as genetic data on how adipokines may contribute to various aspects of the homeostasis of the skin, e.g., melanogenesis, hair growth, or wound healing, just as to the pathogenesis of dermatological diseases such as psoriasis, atopic dermatitis, acne, rosacea, and melanoma.

Ischemia-modified albumin as a possible marker of oxidative stress in patients with telogen effluvium. An Bras Dermatol 2020; 95:447-451. [PMID: 32482549 PMCID: PMC7335859 DOI: 10.1016/j.abd.2020.01.005] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2019] [Accepted: 01/10/2020] [Indexed: 12/27/2022] Open
Abstract
BACKGROUND Telogen effluvium is the most common form of non-scarring alopecia characterized by diffuse hair loss. Ischemia-modified albumin is a marker of oxidative stress and inflammation. OBJECTIVE The aim of this study was to compare the levels of ischemia-modified albumin of telogen effluvium patients with healthy controls. METHODS Ninety-one patients diagnosed with telogen effluvium and 35 healthy volunteers were included in the study. Serum ischemia-modified albumin level was determined by a fast-colorimetric method, and albumin cobalt binding test. The results were evaluated statistically. RESULTS There was no statistically significant difference between the serum albumin values of patient and control groups (p=0.739). Serum ischemia-modified albumin values were significantly higher in the patients with telogen effluvium than healthy controls (p<0.001). STUDY LIMITATIONS Body mass index values of the patient and control groups could not be calculated. CONCLUSIONS To the best of the authors' knowledge, this is the first clinical study to investigate the role of oxidative stress in the pathogenesis of telogen effluvium using ischemia-modified albumin as a biomarker. Based on the results of the present study, it can be considered that oxidative stress plays an important role in the pathogenesis of telogen effluvium. There is a need for further studies to support the results of this study, to demonstrate the possible effects of oxidative stress, and to investigate the other oxidative stress markers in the pathogenesis of telogen effluvium.
