Chen Y, Dong X, Wang Y, Li Y, Xiong L, Li L. Serum 25 hydroxyvitamin D in non-scarring alopecia: A systematic review and meta-analysis. J Cosmet Dermatol 2023. [PMID: 38010941 DOI: 10.1111/jocd.16093] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Revised: 09/18/2023] [Accepted: 11/09/2023] [Indexed: 11/29/2023]
Abstract
INTRODUCTION Non-scarring alopecia mainly includes androgenetic alopecia (AGA), female pattern hair loss (FPHL), alopecia areata (AA), telogen effluvium (TE), anagen effluvium (AE) and so on. Many studies had investigated the serum 25-hydroxyvitamin D level and vitamin D deficiency of patients with these diseases, but opinions varied, and no conclusion was reached. METHODS Relevant articles were retrieved through PubMed, Web of Science, EMBASE, Cochrane Library, China National Knowledge Infrastructure (CNKI) and other databases. Serum 25-hydroxyvitamin D [25(OH) D] levels and vitamin D deficiency were used as our primary outcome. The odds ratio (OR) and the standardized mean difference (SMD) with 95% confidence interval were both examined for vitamin D deficiency and levels. RESULTS Our meta-analysis had included a total of 3374 non-scarring alopecia patients and 7296 healthy controls from 23 studies through the inclusion criteria and exclusion criteria. We found non-scarring alopecia had decreased serum 25(OH)D level (WMD -7.29; 95% CI -9.21, -5.38) and increased vitamin D deficiency incidence (OR 3.11 95% CI 2.29, 4.22), compared with healthy controls. This meta-analysis chose to conduct random-effect model and subgroup analysis, because of the high heterogeneity (serum 25(OH)D level: I2 = 95%, vitamin D deficiency: I2 = 0%). CONCLUSION Patients with non-scarring alopecia (including AA, FPHL, AGA and TE) have insufficient serum level of 25(OH)D and increased incidence of vitamin D deficiency. Vitamin D supplementation and monitoring for vitamin D deficiency may be helpful in treating non-scarring alopecia.

Abstract
INTRODUCTION Alopecia areata (AA) is an autoimmune non-scarring hair loss. The role of micronutrients such as iron, zinc, and vitamins, especially vitamin D, on the natural hair cycle is well defined in literature. This study aims to evaluate the correlation between vitamin D and CRP levels in patients with alopecia areata. METHODS This cross-sectional study was performed from beginning of October 2020 until end of December 2021. Alopecia areata patients over 18 years of age gave their written consent to participate in the study. The severity of the patients' disease was assessed using the Severity of Alopecia Tool. Serum vitamin D and CRP levels were measured and CBC and LFT were also performed. RESULTS There were significant differences between the patients with the localized form of AA and its universal form in the following variables: Vitamin D levels, SALT score, WBC, ALKP, and CRP. There was also a significant inverse correlation between CRP and vitamin D levels (p < 0.0001). CONCLUSION Vitamin D deficiency is associated with higher CRP levels, and patients with low serum vitamin D and high CRP levels are at a higher risk of developing the universalis form of AA; therefore, these patients should undergo more aggressive treatments.

Abstract
Background Alopecia areata (AA) has been postulated to be an autoimmune disease affecting the hair follicles. Because vitamin D receptors are present in the immune system and hair follicles, vitamin D has been hypothesized to affect the disease. Objective The aim of this study was to determine serum 25-hydroxyvitamin D levels and the percentage of vitamin D deficiency in AA patients and compare them with those in healthy controls in a Philippine tertiary hospital. Methods This cross-sectional study included 29 AA patients and 29 healthy controls. The serum 25-hydroxyvitamin D levels were determined using the chemiluminescent immunoassay method. Results There was no significant difference in the mean vitamin D levels between AA patients (24.41 ± 6.87 ng/mL) and healthy controls (24.68 ± 6.68 ng/mL) (P = .88). The percentage of patients with vitamin D deficiency, defined as <20 ng/mL, trended to higher among AA patients (34.4%) than among healthy controls (17.2%), with an odds ratio of 2.53 (95% CI 0.73-8.65), though this was not statsitically significant. Limitations This study involved a limited number of patients in an urbanized area in the Philippines, and majority of the AA cases seen had mild AA. Conclusion The trend toward the increased percentage of vitamin D-deficient individuals among AA patients seen in this study may provide insight into the association of vitamin D with AA.

Abstract
BACKGROUND Alopecia areata (AA) is an autoimmune disorder and chronic recurrent inflammatory disease that results in non-scarring hair loss. OBJECTIVES Our aim is to investigate several parameters related to autoimmunity and inflammation in AA patients and to evaluate their association with this disease. METHODS This study included a total of 672 eligible AA patients and 580 age- and sex-matched healthy individuals who were treated at a third-class hospital in Hefei from January 2016 to May 2020. Data for serum C-reactive protein (CRP), 25-hydroxy vitamin D (25(OH)D), T3, T4, thyroid-stimulating hormone (TSH), thyroid antibodies (TPOAbs and TGAbs), antinuclear antibodies (ANA), complements (C3, C4), and several immunoglobulins (IgA, IgM, and IgG) were collected in this study. RESULTS Regarding autoimmune-related functional indicators, there were no statistically significant differences between TSH, TGAbs, C3, C4, IgA, IgM, and IgG levels between AA patients and healthy controls. Only T3, T4, TPOAbs, and ANA values were significantly abnormal in the AA group compared with the healthy individuals (p < 0.05). In addition, the mean serum 25(OH)D concentration was significantly lower in the patient group than that in control group (p < 0.05), and serum CRP was significantly increased (p < 0.05). CONCLUSION Although the etiopathogenesis of AA is not clear, the importance of monitoring the levels of T3, T4, TPOAbs, ANA, and 25 (OH)D in AA cases is indispensable.

Abstract
BACKGROUND Vitamin D, a vitamin and hormone, plays an important role in dermatology and dermatotherapeutics, due to its anti-inflammatory and immunomodulatory properties, and regulation of keratinocyte differentiation and proliferation. It also affects the hair cycle, and its role in hair loss is under constant research. OBJECTIVES This review aims to give a brief overview of vitamin D biology within the hair follicle, role in the etiopathogenesis, and rationale for supplementation in various alopecias. METHODS A PubMed literature search was performed to review relevant current literature and studies investigating the role of vitamin D in the etiopathogenesis, as a supplement and a potential therapeutic modality in hair loss. RESULTS AND CONCLUSION Vitamin D is intricately involved in various signaling pathways of growth and differentiation of hair follicles. Most studies show an inverse relationship between serum vitamin D levels and non-scarring alopecias such as telogen effluvium, androgenetic alopecia, alopecia areata, and trichotillomania. Vitamin D deficiency is also associated with scarring alopecia. However, conclusive studies to demonstrate the benefit of vitamin D administration in correcting hair loss and managing these conditions are lacking. Hence, further studies are needed before vitamin D can be routinely recommended as a treatment modality in these conditions.

Abstract
Hereditary vitamin D dependent rickets type II is a rare genetic disorder in children characterized by early onset of rickets and deranged biochemical parameters. Low serum calcium level, high alkaline phosphatase, high parathyroid hormone, and high values of 1,25-dihydroxy vitamin D are characteristic biochemical findings. We are reporting a rare case of Vitamin D Dependent Rickets and subsequent improvement after addition of cinacalcet. This is a case report of a 2.5-year-child with Hereditary Vitamin D Dependent Rickets type II receiving cinacalcet as adjunct to oral calcium and calcitriol. Oral cinacalcet (0.25mg/kg/day) was added to the regimen as an adjunct after treatment failure with high dose of oral calcium and calcitriol. A significant improvement in radiological findings and normal homeostasis of calcium, phosphate and parathyroid hormone was achieved after initiation of cinacalcet.

Abstract
This study was carried out to investigate the relationship between common variants in two vitamin D pathway genes (VDR and CYP27B1) and vitamin D3 serum levels. In this study, serum vitamin D metabolite levels were measured in the blood samples of 200 patients with alopecia areata. Then, single nucleotide polymorphisms (SNPs) in VDR and CYP27B1 were analyzed using polymerase chain reaction (PCR)-sequencing. Sixty-three variations were observed in these genes (42 variations in CYP27B1 and 21 variations in VDR). A significant difference in Rs1544410 (odds ratio: 7, P < 0.0005) and rs4646536 (odds ratio: 4.043, P < 0.0005) variants was found between the patients and controls. The study showed the relationship between the two polymorphisms, Rs1544410 (odds ratio: 7, 95% CI, 1–8) and rs4646536 (odds ratio: 4.043, 95% CI, 3–14.038) on the genes VDR and CYP27B1, respectively, with increased risk of developing vitamin D3 insufficiency in the Iranian population. Therefore, SNPs in the VDR and CYP27B1 genes can be considered as prognostic biomarkers of the risk of developing vitamin D3 deficiency.

Abstract
Patients suffering from alopecia areata (AA) can lose hair in focal regions, the complete scalp, including eyelashes and eyebrows, or even the entire body. The exact pathology is not yet known, but the most described theory is a collapse of the immune privilege system, which can be found in some specific regions of the body. Different treatment options, local and systemic, are available, but none of them have been proven to be effective in the long term as well for every treatment there should be considered for the possible side effects. In many cases, treated or non-treated, relapse often occurs. The prognosis is uncertain and is negatively influenced by the subtypes alopecia totalis and alopecia universalis and characteristics such as associated nail lesions, hair loss for more than 10 years and a positive familial history. The unpredictable course of the disease also makes it a mental struggle and AA patients are more often associated with depression and anxiety compared to the healthy population. Research into immunology and genetics, more particularly in the field of dendritic cells (DC), is recommended for AA as there is evidence of the possible role of DC in the treatment of other autoimmune diseases such as multiple Sclerosis and cancer. Promising therapies for the future treatment of AA are JAK-STAT inhibitors and PRP.

Abstract
Differential distributions of vitamin D were observed in the Indian population. Vitamin D levels was inversely correlated with SARS-CoV-2 infection rate. COVID-19 mortality rate was negatively associated with mean vitamin D levels.
Background The role of vitamin D in the susceptibility and severity of various viral diseases has been well documented. Recently, some reports highlighted the possible importance of vitamin D in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Although India receives adequate sunlight throughout the year, the majority of Indians are deficient in vitamin D levels. In the present study, we hypothesized that vitamin D deficiency would be associated with the SARS-CoV-2 infection rate and mortality in the Indian population. Materials and methods SARS-CoV-2 infection and mortality data were obtained from the Government of India's official website (accessed on 16th August 2020). Various literature databases like PubMed and Google Scholar were searched to find the mean of 25-hydroxyvitamin D [25(OH)D] levels in different states and union territories of India, Pearson correlation was carried out to investigate the possible link between mean 25(OH)D levels and SARS-CoV-2 infection and mortality per million of the population. Results An inverse correlation was observed between the mean level of 25(OH)D and SARS-CoV-2 infection rate (r = −0.43, p = 0.02) and mortality rate (r = −0.42, p = 0.02). Conclusions The present observational study revealed an association of vitamin D with SARS-CoV-2 infection and related mortality. Further studies are required to validate our observations.

Abstract
Introduction To investigate the associations of alopecia areata (AA) with serum vitamin D and calcium levels. Methods A systematic review of all relevant articles published up to February 2020 in PubMed, Embase, and Cochrane Library databases was conducted. Primary endpoints were serum 25-hydroxyvitamin D [25(OH)D] levels and vitamin D deficiency, and the secondary endpoint was serum calcium level. Odds ratio (OR) and standardized mean difference (SMD) with 95% CI across studies were analyzed. Results Data on 1585 patients with AA and 1114 controls from 16 case–control studies and three cross-sectional studies were included in this meta-analysis. A pooled meta-analysis was conducted using the random-effects model because of inter-study heterogeneity (vitamin D level, I2 = 87.90%; vitamin D deficiency, I2 = 81.10%; serum calcium level, I2 = 83.80%). A combined analysis revealed that patients with AA had significantly lower mean serum 25(OH)D level compared with control (WMD − 9.08, 95% CI − 11.65, − 6.50, p < 0.001), and were more likely to have vitamin D deficiency (OR 4.14, 95% CI 2.34, 7.35, p < 0.001). However, the pooled analysis revealed that patients with AA did not have significantly lower serum calcium levels compared with control (WMD − 0.17, 95% CI − 0.40, 0.06, p = 0.143). Subgroup analysis suggested that matched control, mean age, and country might contribute to the heterogeneity of serum vitamin D level, while study design, matched control, and country might contribute to the heterogeneity of vitamin D deficiency. Conclusion Deficiency of serum 25(OH)D level, rather than calcium level, was present in patients with AA. Screening for vitamin D deficiency and vitamin D supplementation may be beneficial in the treatment of patients with AA.

Abstract
BACKGROUND Vitamin D deficiency had been associated with various hair loss disorders, such as telogen effluvium, alopecia areata, and female pattern hair loss. However, previous studies have not found a correlation between serum vitamin D levels and the severity of androgenetic alopecia. METHODS A case-control study was conducted for a period of one year in a public tertiary care hospital. Fifty males clinically diagnosed with androgenetic alopecia and 50 age-matched healthy controls were recruited. Serum vitamin D levels in both cases and controls were measured by radioimmunoassay technique, and the results were compared. RESULTS A total of 50 cases and 50 controls were recruited and analyzed. The mean age of the cases was 23 years and that of controls was 24.2 years. The mean levels of serum vitamin D significantly decreased in cases, compared to controls (20.10 vs. 29.34 ng/mL; P ≤ 0.001). Eighty-six percent of the cases had deficiency of vitamin D (<30 nmol/L), while 14% had insufficient vitamin D levels (31-50 nmol/L). There was a positive correlation between vitamin D deficiency and severity of androgenetic alopecia (AGA), which was statistically significant (P ≤ 0.5). However, there was no correlation between the duration of sun exposure and serum vitamin D levels (2.36 ± 1.2 in cases and 3.23 ± 1.6 in controls, P value = 0.98). CONCLUSION Our study showed a significant correlation between vitamin D deficiency and the severity of androgenetic alopecia. This suggests that vitamin D may play a role in the premature onset of androgenetic alopecia. However, further studies on a larger population and the effect of vitamin D supplementation on the progression of androgenetic alopecia are required to validate the above findings.

Abstract
BACKGROUND It has been suggested that low vitamin D levels may affect the development of hair loss. AIMS Our aim was to evaluate the serum 25-hydroxy vitamin D [25(OH)D] status in Chinese patients with alopecia areata (AA), female pattern hair loss (FPHL), and male androgenetic alopecia (MAGA) compared with healthy individuals. METHODS We performed a case-control study including 443 AA patients, 657 FPHL patients, 777 MAGA patients, and 2070 normal controls (1064 male and 1006 female healthy individuals) from 2015 to 2017 to analyze the correlation of serum 25(OH)D levels and hair loss in a Chinese population. RESULTS Serum 25(OH)D levels stratified by age, sex, and season were compared between patients and healthy individuals. AA patients' serum 25(OH)D levels were statistically lower than that of controls (P < .0001, α = .05). Serum 25(OH)D levels of FPHL patients (P < .0001, α = .05) and MAGA patients (P = .0005, α = .05) were also significantly lower than counterpart control subjects. CONCLUSION Our findings suggest an association between serum 25(OH)D levels and alopecia areata, female pattern hair loss, or male androgenetic alopecia in a Chinese population.
