BACKGROUND
Vitiligo, a common dermatological disorder in Saudi Arabia, is associated with significant psychological impacts. This study explores the relationship between vitiligo and the severity of Major Depressive Disorder (MDD), highlighting the broader implications on mental health among affected individuals.
OBJECTIVE
To assess the prevalence and predictors of depression among adult vitiligo patients, and to examine the relationship between MDD severity and vitiligo.
METHODS
Employing a cross-sectional design, the research utilized the Vitiligo Area Severity Index (VASI) and the Patient Health Questionnaire-9 (PHQ-9) to measure the extent of vitiligo and depression severity respectively. The study involved 340 diagnosed vitiligo patients from various healthcare settings. Logistic and ordinal regression analysis were applied to evaluate the impact of sociodemographic variables and vitiligo types on MDD severity.
RESULTS
The prevalence of MDD was 58.8% (200 out of 340 participants). Depression severity varied notably: 24.7% of patients experienced mild depression, 31.1% moderate, 22.6% moderately severe, and 21.6% severe depression. Female patients had higher odds of severe depression compared to males (aOR = 3.14, 95% CI: 1.93-5.1, P < .001). Age was inversely related to depression severity, with patients over 60 years showing significantly lower odds (aOR = 0.1, 95% CI: 0.03-0.39, P < .001). Lower income was associated with higher depression severity (aOR = 10.2, 95% CI: 3.25-31.8, P < .001). Vitiligo types also influenced depression severity; vulgaris (aOR = 5.3, 95% CI: 2.6-10.9, P < .001) and acrofacial vitiligo (aOR = 2.8, 95% CI: 1.5-5.1, P < .001) were significantly associated with higher depression levels compared to focal vitiligo.
CONCLUSIONS
The findings suggest that vitiligo contributes to an increased risk of severe depression, highlighting the need for integrated dermatological and psychological treatment approaches to address both the physical and mental health aspects of the disease.

Vitiligo is an autoimmune disease characterized by epidermal melanocyte destruction, with abnormal autoimmune responses and excessive oxidative stress as two cardinal mechanisms. Human umbilical mesenchymal stem cells-derived exosomes (hUMSCs-Exos) are regarded as promising therapeutic choice for autoimmune diseases due to potent immunosuppressive and anti-oxidative properties, which can be potentiated under 3D cell culture condition. Nevertheless, whether exosomes derived from 3D spheroids of hUMSCs (3D-Exos) exhibit considerable therapeutic effect on vitiligo and the underlying mechanism remain elusive. In this study, systemic administration of 3D-Exos showed a remarkable effect in treating mice with vitiligo, as revealed by ameliorated skin depigmentation, less CD8T cells infiltration, and expanded Treg cells in skin, and 3D-Exos exerted a better effect than 2D-Exos. Mechanistically, 3D-Exos can prominently facilitate the expansion of Treg cells in vitiligo lesion and suppress HO-induced melanocytes apoptosis. Forward miRNA profile analysis and molecular experiments have demonstrated that miR-132-3p and miR-125b-5p enriched in 3D-Exos greatly contributed to these biological effects by targeting Sirt1 and Bak1 respectively. In aggregate, 3D-Exos can efficiently ameliorate vitiligo by simultaneously potentiating Treg cells-mediated immunosuppression and suppressing oxidative stress-induced melanocyte damage via the delivery of miR-132-3p and miR-125b-5p. The employment of 3D-Exos will be a promising treament for vitiligo.

BACKGROUND
The total glucoside of paeony (TGP) is recognized for its immunomodulatory properties and anti-inflammatory effects. This study evaluates the efficacy of TGP combined with oral mini-pulse therapy (OMP) and narrow-band ultraviolet B (NB-UVB) in treating active nonsegmental vitiligo (NSV).
MATERIALS AND METHODS
The combination therapy was contrasted against those from a group treated solely with OMP and NB-UVB. Data from 62 patients undergoing TGP combination treatment and 55 without were analyzed over a 3-month period. After 6 months, the differences in recurrence rate were investigated by follow-up.
RESULTS
The findings indicate that integrating TGP may yield superior outcomes compared to OMP + NB-UVB alone. Moreover, the patient's oxidative stress makers were significantly reduced after the treatment. The majority of patients in the TGP cohort exhibited enhanced skin pigmentation over the duration. Notably, no increase in side effects or recurrence was observed in this group. Especially, patients with vitiligo on their head and neck experienced pronounced improvements.
CONCLUSION
The efficacy of the combination treatment group was better than that of the control group at 2 and 3 months, and there was no difference in recurrence rate and side effects, suggesting that TGP may continue to show efficacy in NSV for a longer period of time by reducing the level of oxidative stress, and is especially suitable for patients with head and neck lesions.

BACKGROUND
The pathogenesis of vitiligo remains elusive. Emerging evidence suggests that vitiligo is an immune-mediated disorder, in which a plethora of immune cells play pivotal roles. However, the association between circulating immune cells and vitiligo continues to be enigmatic.
MATERIALS AND METHODS
We extracted single nucleotide polymorphisms (SNPs) associated with immune circulating cells at a genome-wide significance level from the BLOOD CELL CONSORTIUM's genome-wide association study (GWAS) dataset. Summary data for 385,801 cases of vitiligo were obtained from a large-scale Finnish genome-wide association study (ncases=292, ncontrols=385,509). The inverse variance weighted (IVW) method was employed as the primary analytical approach for Mendelian randomization (MR) analysis. Additionally, heterogeneity was assessed using Cochran's Q value, and horizontal pleiotropy was evaluated using MR-Egger Mendelian Randomization Pleiotropy RESidual Sum and Outlier and leave-one-out analyses.
RESULTS
The risk of vitiligo was found to increase with the elevation of 4 circulating immune cells, as evidenced by the odds ratios (ORs) and 95% confidence intervals (CIs): basophils (OR=1.81; 95% CI: 1.01-3.24, p=0.0450), monocytes (OR=1.67; 95% CI: 1.23-2.26, p=0.0009), eosinophils (OR=1.78; 95% CI: 1.22-2.59, p=0.0028), and neutrophils (OR=1.65; 95% CI: 1.08-2.54, p=0.0208). After removing outliers, the sensitivity analysis of the above indicators did not show heterogeneity and pleiotropy.
CONCLUSION
Our findings illuminate the association between circulating immune cells and vitiligo, offering insights that could guide clinical practices in the treatment of vitiligo.

AIMS AND OBJECTIVES
The aim of this study is to systematically review randomized controlled clinical trials (RCTs) studying various types of regenerative medicine methods (such as platelet-rich plasma, stromal vascular fraction, cell therapy, conditioned media, etc.) in treating specific dermatologic diseases. Rejuvenation, scarring, wound healing, and other secondary conditions of skin damage were not investigated in this study.
METHOD
Major databases, including PubMed, Scopus, and Web of Science, were meticulously searched for RCTs up to January 2024, focusing on regenerative medicine interventions for specific dermatologic disorders (such as androgenetic alopecia, vitiligo, alopecia areata, etc.). Key data extracted encompassed participant characteristics and sample sizes, types of regenerative therapy, treatment efficacy, and adverse events.
RESULTS
In this systematic review, 64 studies involving a total of 2888 patients were examined. Women constituted 44.8% of the study population, while men made up 55.2% of the participants, with an average age of 27.64 years. The most frequently studied skin diseases were androgenetic alopecia (AGA) (45.3%) and vitiligo (31.2%). The most common regenerative methods investigated for these diseases were PRP and the transplantation of autologous epidermal melanocyte/keratinocyte cells, respectively. Studies reported up to 68.4% improvement in AGA and up to 71% improvement in vitiligo. Other diseases included in the review were alopecia areata, melasma, lichen sclerosus et atrophicus (LSA), inflammatory acne vulgaris, chronic telogen effluvium, erosive oral lichen planus, and dystrophic epidermolysis bullosa. Regenerative medicine was found to be an effective treatment option in all of these studies, along with other methods. The regenerative medicine techniques investigated in this study comprised the transplantation of autologous epidermal melanocyte/keratinocyte cells, isolated melanocyte transplantation, cell transplantation from hair follicle origins, melanocyte-keratinocyte suspension in PRP, conditioned media injection, a combination of PRP and basic fibroblast growth factor, intravenous injection of mesenchymal stem cells, concentrated growth factor, stromal vascular fraction (SVF), a combination of PRP and SVF, and preserving hair grafts in PRP.
CONCLUSION
Regenerative medicine holds promise as a treatment for specific dermatologic disorders. To validate our findings, it is recommended to conduct numerous clinical trials focusing on various skin conditions. In our study, we did not explore secondary skin lesions like scars or ulcers. Therefore, assessing the effectiveness of this treatment method for addressing these conditions would necessitate a separate study.

INTRODUCTION
Despite the promising results in terms of effectiveness of anticancer treatments, a wide range of dermatologic adverse reactions have been reported. Among them, skin photosensitivity, defined as a range of dermatologic conditions caused or exacerbated by sunlight exposure, is an emerging adverse event.
EVIDENCE ACQUISITION
A review of the current literature was performed to report the most characteristic phototoxic and photoallergic reactions associated with anticancer therapies, as well as other characteristic manifestations potentially related to photo-exposure, including UV recall, vitiligo-like reactions, drug-induced cutaneous lupus erythematosus, and UV-induced hyperpigmentation.
EVIDENCE SYNTHESIS
A total of 30 manuscripts were collected in the present review, reporting several phototoxic and photoallergic reactions associated with anticancer therapies.
CONCLUSIONS
Photosensitivity reactions are an increasing challenge in cancer management. The raising awareness about this adverse event has increased the identification of potential photosensitizing drugs as well as its prevention and the management. However, more studies are required to improve the knowledge of this cutaneous toxicity and to define a personalized treatment strategy.

Background Numerous clinical signs and symptoms are thought to be associated with insulin resistance. The purpose of this study was to examine the prevalence of insulin resistance among male medical students attending a private Saudi Arabian institution, based on clinical indications. Methods A convenient non-probability sample consisting of 241 male medical students was used to conduct cross-sectional research. Each participant had an in-person interview as well as anthropometric measurements. The interview consisted of a questionnaire that was used to assess demographic data and clinical manifestations related to insulin resistance. Results The study demonstrated the connection between a few dermatological symptoms and waist circumference as an indicator of insulin resistance. In both the high and normal waist circumference groups, acne was the most common symptom. There was no correlation found between waist circumference and psoriasis, hidradenitis suppurativa, androgenic alopecia, alopecia areata, or vitiligo. Nevertheless, as an indicator of insulin resistance, waist circumference was statistically significantly correlated with both skin tags and acanthosis nigricans. Most students had excessive day sleep, foggy brains, struggled with planning and solving problems, and had a memory that became worse in the past few years. In addition, many students feel hungry even after eating some sweets and usually have extreme thirst. Conclusion Among medical students, skin tags, acanthosis nigricans, and acne were the most prevalent dermatological manifestations. Clinicians need to be aware that skin conditions, sleep difficulties throughout the day, changes in cognition, and food cravings might all be indicators of internal changes and/or illnesses such as diabetes and prediabetes.

Background Psoriasis is a common chronic inflammatory skin disease with an autoimmune etiology. Psoriasis has been presumed to be associated with several autoimmune diseases. We sought to determine the prevalence of autoimmune diseases in patients with psoriasis in a large referral tertiary care center. Methods This is a retrospective and cross-sectional chart review of patients with confirmed psoriasis diagnoses in the dermatology clinic of King Abdulaziz Medical City, Riyadh, Saudi Arabia. The electronic charts of patients were individually reviewed for autoimmune diseases such as hypothyroidism, hyperthyroidism, alopecia areata, vitiligo, atopic dermatitis, and inflammatory bowel diseases like Crohn's disease and celiac diseases. Results A total of 839 cases were included, 56.4% of whom were females. Most patients were between 31 and 50 years old (37.1%). The most common autoimmune disease was hypothyroidism (6.8%), seen more in females. The second most common autoimmune disease was alopecia areata (3.6%), followed by atopic dermatitis (2.9%). Rheumatoid arthritis, systemic lupus erythematosus, and inflammatory bowel diseases were uncommon in our cohort. Conclusion In this single-center retrospective cohort of patients with psoriasis, hypothyroidism and alopecia areata were the most commonly encountered autoimmune diseases. Larger, multi-center studies are needed to evaluate the prevalence of autoimmune diseases among patients with psoriasis.

BACKGROUND
Vitiligo is a dermatological condition characterized by the appearance of white spots or patches on the skin due to the loss of skin pigment called melanocytes. The estimated prevalence of vitiligo is about 0.5-2% of the world population, but in India, the prevalence rate varies from 2 to 8%, depending on the region. This study aimed to assess drug prescribing patterns in vitiligo patients.
MATERIALS AND METHODS
A prospective cross-sectional study was carried out in the Dermatology Department of Government General Hospital, Andhra Pradesh, India, from December 2019 to 2020. Patients aged ≥18 years, both genders, and diagnosed and receiving treatment for vitiligo were included in the study. All medicines prescribed to the patients were collected on the predesigned case report form. Ethical approval for this study was taken from the Institutional Ethics Committee of Rajiv Gandhi Institute of Medical Science (RIMS). The collected data were analyzed by using SPSS version 18.
RESULTS
The most commonly prescribed class of drugs was corticosteroids (42.9%), followed by calcineurin inhibitors (13.4%), vitamins (14.6%), basic fibroblast growth factor (BFGF) (9.5%), moisturizers (6.9%), antihistamines (6.5%), and minerals (6.2%). Among corticosteroids, betamethasone was the most commonly prescribed drug, followed by clobetasol propionate. Topical drugs were prescribed more often than orally.
CONCLUSION
The prescription pattern in vitiligo patients is as per the guidelines and recommendations. However, further studies using multiple centers are recommended to verify our findings.
