Prostaglandins and their analogues are beneficial as topical agents in vitiligo treatment, yet neither of the previous study addressed their comparative efficiency with conventional topical agents used in vitiligo treatment. In this pilot (24 patients) left-right comparative study we addressed efficiency of prostaglandin F2α analogue latanoprost versus tacrolimus when combined with narrow-band ultraviolet B and microneedling in repigmentation of nonsegmental vitiligo lesions. Our results confirm potency of prostaglandins, in particular, that of latanoprost, in inducing repigmentation, with the efficiency being at least comparable to that of tacrolimus, while contribution of microneedling remains unclear. In summary, results of our study provide further evidences for justified use of prostaglandins, in particular, latanoprost, in vitiligo treatment. In turn, this warrants future studies on the topic aiming to conclusively introduce prostaglandin-based formulations as conventional agents for vitiligo management.

Coronavirus 2019 (COVID 19) was first detected in December 2019 in China. It has become a pandemic. With concern about therapies that may decrease immunity and enhance the severity of an indivduals's COVID‐19 infection, leading to a possibly fatal outcome, use of immunosuppressants has become an important concern. This work focuses on management of various skin diseases individuals lacking immunity to COVID‐19 but requiring a systemic immunosuppressant, keeping in view the challenge of the COVID 19 pandemic and that our knowledge of this virus and its effects on the immune system are incomplete including knowledge as to an individual's immunity after COVID‐19 infection.

Vitiligo progression is attributed to immune system malfunctioning, thus immunomodulating compounds might be beneficial in stopping vitiligo progression which is a prerequisite for successful repigmentation. The goal of this study was to assess efficacy of acridone acetic acid, sodium salt (Na-AAA), an immunomodulating compound with favorable safety profile, in stabilizing active vitiligo, and to reveal prognostic factors of treatment outcome. Sixty consecutive patients with progressing nonsegmental vitiligo were treated with 10 i.m. injections of Na-AAA every other day. Disease stability was assessed in 1, 3, 6, and 12 months post-treatment. Statistical analysis was applied to correlate treatment outcome and available clinical parameters. Of the 60 patients treated, vitiligo stopped progression in 44 patients (73.3%). Older age (p = 0.0219), age of 35 and older (p = 0.0189, odds ratio (OR) = 5.2, 95% confidence interval (CI) 1.30-20.84) or age of 40 and older (p = 0.0039, OR = 6.48, 95% CI 1.86-22.61), longer disease duration (p = 0.0234), pre-treatment interleukin-6 level over 2 pg/mL (p = 0.0005, OR = 13.7, 95% CI 2.97-63), and over the reference threshold value 5.9 pg/mL (p = 0.0009, OR = 25.8, 95% CI 2.8-239) as well as presence of other autoimmune diseases (p = 0.038, OR = 7.0, 95% CI 1.14-42.97) were negative prognostic factors of treatment success. In conclusion, acridone acetic acid, sodium salt, emerges as an efficient option for stopping vitiligo progression.

Vitiligo is a non‐lethal, non‐communicable, immune‐mediated, and generally progressive skin disease, with poorly understood etiopathogenesis and weak evidence base. The aim of the study is to contribute to the scant research on the patient‐reported outcomes in vitiligo, and to examine the presence of associations between various inputs for possible use in clinical practice. The study was designed as a web‐based questionnaire with 40 inputs across seven dimensions. The questions include demographics, skin type, eye and natural hair color, age of respondent and age of onset, possible triggers, disease extent, localization, progression and activity, the efficacy of most common treatment modalities, medication side‐effects, heredity and diseases among parents, and out‐of‐pocket expenses for treatments to date. The analysis presented with this work contributes to the discussion about the relation between therapies, socio‐economic factors, and treatment outcomes in vitiligo. All physicians should adequately manage patient expectations in terms of overall treatment duration and expected out‐of‐pocket expenses, and actively evaluate patients at shorter intervals. A more aggressive therapeutic approach using telehealth devices should be considered to supplement therapy, monitor treatment progress, and protocol compliance.
