Introduction: Chronic spontaneous urticaria (CSU) is the most commonly diagnosed skin condition in dermatology outpatient departments. Second-generation antihistamines are shown to be effective in the control of CSU. As per the guidelines, a combination of antihistamines is less recommended due to the lack of synergistic effect, though used widely. Exploring effective treatment options are crucial, given the challenges posed by CSU.

Aims and objectives: To assess the safety and efficacy of Bilastine up-dosing versus combination of 20 mg Bilastine with 5 mg Levocetirizine in the treatment of CSU.

Materials and methods: This prospective randomized non-blinded comparative trial involved 62 patients, with 32 in group A and 30 in group B. Group A received Tablet Bilastine 20 mg bd, while Group B received a combination of Tablet Bilastine 20 mg and Tablet Levocetirizine 5 mg. Urticarial Activity Score 7 was performed at baseline and follow-up visits (every 2 weeks for 6 weeks).

Results: Both groups had a higher number of male patients in the 20-30 years age group. Angioedema was present in 15.6% of group A and 23.3% in group B. After 6 weeks, both the groups showed a significant improvement in UAS 7 scores (P value <0.05). Group A demonstrated a remarkable reduction in UAS 7 from 19.4% to 0.03% with minimal side effects.

Conclusion: Bilastine up-dosing proved to be efficient, secure, and well tolerated when compared to the combined dose of Levocetirizine 5 mg and Bilastine 20 mg, suggesting that up-dosing of Bilastine could be a valuable addition to the current medication arsenal with the minimal side effects.

Androgenetic alopecia (AGA) is defined as the alopecia induced by androgens in genetically predisposed individuals. AGA results in progressive miniaturization of the hair follicles leading to vellus transformation of terminal hair. The high prevalence and wide range of expressed phenotypes in AGA is a result of a polygenic inheritance mode. The androgen receptor (AR) gene located on the X chromosome at Xq11-12 is the first gene to show genetic association with AGA. Newer genetic associations with AGA are under study. In early-onset AGA, obesity, diabetes, hypertension, dyslipidaemia, insulin resistance, benign prostatic hyperplasia (BPH), prostate cancers and coronary artery disease (CAD) are associated with AGA. Screening of early-onset AGA patients and intervention for metabolic syndrome and insulin resistance can prevent the development of cardiovascular disease (CVD) at an early stage. As effective treatments continue to be topical minoxidil, systemic finasteride and hair transplantations, newer modalities are under investigation. Understanding the genetic factors involved in AGA and continued research into newer therapies, such as cell-based therapies, will lead to effective treatment and improve the quality of life in patients with AGA.

Background: Rosacea is a chronic inflammatory skin disease. Previous studies have determined that IL-36, IL-37, and IL-38 may play a role in the pathogenesis of various inflammatory diseases.

Aims and objectives: The present study aims to evaluate the relationship of these cytokines with rosacea.

Materials and methods: A total of 100 individuals, including 50 patients with rosacea and 50 healthy controls, were included in the study. IL-36, IL-37, and IL-38 levels were measured using the ELISA method by taking serum samples from all participants.

Results: The mean serum levels of IL-36, IL-37, and IL-38 in the patient group were 52.17 ± 24.07 pg/ml, 18.46 ± 8.18 pg/ml, and 25.74 ± 8.36 ng/l, respectively. The mean serum levels of IL-36, IL-37, and IL-38 in the control group were 32.99 ± 19.90 pg/ml, 44.61 ± 22.27 pg/ml, and 45.61 ± 17.32 ng/l, respectively. The difference between the serum levels of IL-36, IL-37, and IL-38 in the patient and control groups was statistically significant (P < 0.001).

Conclusion: Based on these findings, an increase in IL-36 and a decrease in IL-37 and IL-38 may contribute to the pathogenesis of rosacea. Future rosacea treatments could target and/or interact with these possible steps in the pathogenesis of rosacea.
