Background and Aim: Alopecia areata (AA) is a chronic, autoimmune disease that causes non-scarring hair loss. Recently, serum vitamin D has been implicated in the etiopathogenesis of AA due to its immunoregulatory effects. Its deficiency can cause a loss of selftolerance and predispose individuals to autoimmune diseases. This study compared the serum vitamin D levels between AA cases and controls. We aimed to compare the serum levels of vitamin D between AA patients and age and sex-matched healthy controls and to elucidate any correlation between AA and vitamin D serum levels in terms of disease pattern, severity, and extent.Methods: A case group comprising 25 AA patients and a second group of 25 healthy controls of 10 years of age or older were involved in the study. A detailed history was taken, along with a complete clinical examination. Serum vitamin D levels were measured and compared between the groups.Results: The mean level of vitamin D in cases (17.15 ± 5.01 ng/ ml) was significantly lower as compared to controls (34.58 ± 20.83 ng/ml) (P < 0.001). The duration, pattern, and severity of AA had no significant relationship with patients’ serum vitamin D levels.Conclusion: We demonstrated a statistically significant variation in serum vitamin D between controls and cases, with lower values in patients. Our findings indicate a possible cause-and-effect relationship between low serum vitamin D and AA, which needs further exploration.

Background: Hyperhomocysteinemia and vitamin D deficiency maybe involved in the pathogenesis of vitiligo. This study comparedthe serum levels of vitamin D, homocysteine, vitamin B12, andfolic acid between vitiligo-affected children and healthy children.Methods: Using a case-control design, 30 children with vitiligoand 30 age and sex-matched healthy children were enrolledfrom April 2018 to August 2020. Serum levels of vitamin D,homocysteine, vitamin B12, and folic acid were analyzed in bothgroups during the same season of the year. Additionally, theassociation between serum levels of these factors with demographicand clinical features of the children (collected by interview andphysical examination) was evaluated. Data were analyzed usingthe independent T-test, Fisher’s exact test, and chi-squared test.Results: The vitiligo group had significantly lower vitamin Dand folic acid serum levels compared with the control group[95% CI -19.87 to -2.96 and -4.15 to -4.18, respectively]. Amongpatients, the vitamin D level was negatively correlated with age(r = -0.459, P = 0.011) and disease duration (r = -0.373, P = 0.042).Moreover, there was a significant association between vitiligoactivity and serum homocysteine levels (P = 0.027).Conclusion: Routine measurement of vitamin D and folic acidserum levels might be suggested, especially in children withlong-standing disease. Monitoring the homocysteine level maybe beneficial, particularly in children with progressive vitiligo.

Viral skin diseases range from simple superficial exanthems to complex systemic diseases, affecting people of all ages. Careful assessment of infectious contacts and immunization status is of considerable importance along with a thorough physical examination. Recent research has linked a deficiency of vitamin D to an increased risk of autoimmune, infectious, and atopic disorders. Intralesional vitamin D3 may be an effective treatment option for warts. Vitamin D3 derivatives are effective for various skin conditions, including psoriasis, transient acantholytic dermatosis, actinic porokeratosis, and keratosis palmaris et plantaris. Vitamin D3 treatment has been shown to decrease chemokine synthesis and monocyte trafficking, as well as to downregulate toll-like receptors (TLRs) 2 and 4 of monocytes. This suggests an association between TLRs and vitamin-D-mediated innate immunity. The effect of vitamin D derivatives was speculated to be derived from its potential to regulate epidermal cell proliferation and differentiation and to modulate cytokine production. According to some studies gathered here, not only we can use different forms of vitamin D as therapy for viral skin disease, but also there is an important relationship between them. Therefore, we should consider the serum level of vitamin D for better management of these disorders. Also, keeping vitamin D levels within the normal range may be a preventative healthcare strategy.

Background: Vitiligo is a skin disease caused by the destruction of melanocytes of the epidermis, leading to well-defined white patches that are often distributed symmetrically. The presentstudy aimed to determine the correlation relationship between the α-MSH and vitamin D serum levels among Iraqi vitiligo patients. Materials and Methods: This study was done on outpatients who attended the Dermatology and Venereology Consulting Clinic of Salah-Al Deen General Hospital from November 2017 to March 2018. One hundred and ninety individuals were stratified into 110 cases of vitiligo and 80 healthy controls. Serum assays for α-MSH and vitamin D levels were sent for all subjects. Results: Vitiligo patients had significantly lower α-MSH levels and vitamin D levels than the controls (P ≤ 0.01). There was a significant, positive correlation between α-MSH and vitamin D levels in vitiligo patients overall (r = 0.236; P ≤ 0.01), though this correlation was negative within the male and female subgroups (r = -0.392 and -0.661, respectively; P ≤ 0.01). Conclusion: Compared to normal controls, vitiligo patients had significantly lower levels of α-MSH and vitamin D. These findings may back the normalization of both α-MSH and vitamin D levels in vitiligo patients as an important step toward disease recovery.

Background: The use of vitamin D and its analogues in the treatment of warts has been to be effective and painless without any considerable side effects, unlike some other routine safe and effective therapeutic modalities such as cryotherapy that in some cases is really difficult to perform due to related pain, especially in the children. Owing to a probable relationship between the deficiency of serum vitamin D and warts, this research aimed to find the association between level of serum vitamin D and warts. Methods: This case-control study was conducted on 56 subjects in Rasoul Akram Hospital, Tehran, Iran, for 18 months. The subjects were randomly divided into case and control groups, including 28 age and sex-matched subjects in each of them. The required data were extracted through a questionnaire. Finally, the data were analyzed in the SPSS software V.22 using tests such as Mann-Whitney and Pearson correlation. Results: In this study, 56 people were examined, and 28 subjects were included in both case and control groups. The mean serum level of vitamin D in both case and control groups was 23.564and 31.593, respectively. The association between serum levels of vitamin D in the group with and without wart was not significant in both men and female groups. Serum vitamin D levels were compared in two groups of under 18 years old and between 18 and 50 years old, which were not statistically significant. Conclusion: According to our results, there is no significant relationship between serum vitamin D levels and existence of warts. This relationship is not statistically significant at the level of age and sex variables, and there is no difference in age and gender between the case and control groups.

Skin as an outer layer of body and a main connection between the body and the environment is a way that pathogens can access the body; Therefore, it has a crucial protecting role for the body because of obstacle functioning and micobiota. Factors that seem to commonly contribute to the disease are follicular hyperkeratinization, propionibacterium acnes, sebum production, and inflammation; however, pathogenesis of acne vulgaris as an inflammatory skin disorder is still poorly understood. Google Scholar and PubMed databases were searched for all related articles, using the key words of zinc, diet, vitamin D, BMI, and acne vulgaris.

Background: Pemphigus vulgaris (PV) is a rare autoimmune blistering disease of the skin and mucous membranes. Because vitamin D deficiency is associated with many immune disorders, we compared the levels of vitamin D between PV patients and healthy controls. Methods: Vitamin D level of 20 patients with PV was compared with 20 healthy individuals matched for age, gender, hours spent in the sun, body mass index (BMI) and daily vitamin D intake at the same time interval. The severity of the disease was estimated according to ABSIS score. The serum level of 25-hydroxyvitamin D (25OHD) was measured by a commercial ELISA test. Results: Vitamin D deficiency in the pemphigus vulgaris group (75%) was higher than healthy controls (45%) (P = 0.053). Mean level of vitamin D in PV patients was significantly lower than healthy controls, and was in the range of vitamin deficiency (P ? 0.05). No significant relationship was observed between the severity of the PV disease and vitamin D levels (P > 0.05). Conclusions: Based on the results of the present study, the mean level of vitamin D in patients with PV was significantly lower than healthy people. Based on our findings and given the important role of vitamin D in preventing inflammatory and autoimmune diseases, vitamin D deficiency can be considered as a factor triggering the onset of PV.

Background: Generalized vitiligo is characterized by autoimmunedestruction of melanocytes, which results in patches of thedepigmented skin and the overlying hair. Vitamin D is an essentialhormone synthesized in the skin and is responsible for skinpigmentation. Low vitamin D levels have been noted in patientswith a variety of autoimmune diseases. A recent study showedthat low vitamin D levels may be associated with vitiligo. Theaim of this study was to compare 25-hydroxyvitamin D (25[OH]D) levels in Iranian patients with vitiligo with normal controls.Method: In this case-control study, we studied 30 newly diagnosedpatients with vitiligo and 30 healthy controls through a casecontrol design. Two groups were matched for gender, age, andthe season in which the serum levels of 25-hydroxy vitamin Dwere measured. The serum levels were categorized as sufficient,insufficient and deficient.Result: The mean serum level of vitamin D was 10.24±1.27 ng/mL in patients compared to 18.31±7.39 ng/mL in the controlgroup. Male patients had lower levels of vitamin D compared tocontrols (7.25 ng/mL vs. 13.31ng/mL, P=0.03), while no significantdifference was observed between females and controls (14.12 ng/mL vs. 16.25 ng/mL, P=0.51).Conclusion: The present study demonstrated that there may be anassociation between low levels of Vitamin D3 and vitiligo in men.
