Meibography health score: a simple grading system for isotretinoin-induced meibography alterations on patients with acne vulgaris.

PURPOSE: To develop a simple, subjective, and reliable grading scale for isotretinoin-induced meibography changes. METHODS: After analyzing meibography images obtained from systemic isotretinoin users, a grading scale was proposed and named "meibography health score." The score ranged from 1 to 3, with decreasing gland reflectivity and identifiable margins. A total of 11 medical professionals were asked to grade 10 meibography images obtained from isotretinoin users using the proposed scale and were divided into three groups: (A) ophthalmologists with experience with meibography, (B) ophthalmologists with no experience with meibography, and (C) radiologists. The kappa statistic was determined to test interrater reliability. RESULTS: The overall kappa was approximately 0.64. The kappa scores for Groups A, B, and C were 0.78, 0.59, and 0.90, respectively. Grade 2 had the lowest kappa scores (0.62, 0.35, and 0.82 for A, B, and C, respectively) and grade 3 the highest (0.78, 0.90, and 1.0 for A, B and C, respectively). Furthermore, Group C had the highest kappa scores and Group B the lowest. CONCLUSION: The meibography health score exhibited good interrater reliability, particularly in severe cases.

Frequency of use and annual costs of biological therapy for psoriasis in Colombia in 2019.

BACKGROUND: Evidence describing the types and annual costs of biological treatments for psoriasis in Latin America is scarce. This study aimed to estimate the frequency of use and costs of biologic therapy for psoriasis in Colombia in 2019. METHODS: This secondary data analysis uses the International Classification of Diseases terms associated with psoriasis, excluding those related to psoriatic arthritis, based on data from the registry of the Colombian Ministry of Health. We estimated the prevalence of psoriasis per 100,000 inhabitants; then, we retrieved the frequency of use of biologic therapy in patients with psoriasis and estimated the cost per year of each and overall therapies in 2019 in US dollars (USD). RESULTS: There were 100,823 patients with psoriasis in Colombia in 2019, which amounts to a prevalence of 0.2% in the general population. Of those patients, 4.9% received biologic therapy, most frequently males (60%). The most commonly used biological therapies for psoriasis in Colombia in 2019 were ustekinumab (35.2%), with an annual cost per patient of $12,880 USD; adalimumab (26%), with a yearly cost per patient of $7130 USD; and secukinumab (19.8%), with an annual cost per patient of $6825 USD. CONCLUSION: This is the first study to describe the use and cost of biological therapy for psoriasis in Colombia. It provides valuable cost-awareness information for the Colombian health system.

Efficacy and safety of secukinumab in psoriasis: five-year real life experience.

BACKGROUND: The efficacy and safety of secukinumab in psoriasis patients has been demonstrated in randomized controlled clinical trials. OBJECTIVES: The authors aimed to evaluate the efficacy and safety of secukinumab in plaque psoriasis patients followed in our clinic. METHODS: Data from 101 plaque psoriasis patients who received at least 16 weeks of secukinumab treatment between June 2018 and June 2023 were retrospectively analyzed. RESULTS: Fifty-three (53%) of the patients were bionaive. PASI-75, -90, -100 response rates were 72%, 50%, 30% respectively at week 16 in all patients. PASI-75 and -90 responses were higher in naive patients at weeks 16 and 28 (p < 0.001, p < 0.001, p < 0.01, p = 0.01, respectively). The percentage of patients with PASI ≤ 1, ≤ 3, ≤ 5 were 50%, 77%, and 92%, respectively at week 16. They were higher in the naive group than in nonnaive group at weeks 16 and 28 (p = 0.02, p < 0.01, p = 0.05, p = 0.07, p < 0.01, p = 0.03, respectively). At week 52, PASI-75, -90, -100 responses were significantly lower in smoking patients (p = 0.04, p = 0.03, p < 0.01, respectively). The mean duration of secukinumab treatment was 19.80 ±â€¯12.76 months. Secukinumab was discontinued 14 (26.4%) naive patients and 28 (58.3%) nonnaive patients at one occasion during treatment (p < 0.001). The most common adverse event in patients was mucocutaneous candida infection (8%). No hepatitis B or C reactivation and no active or reactivation tuberculosis were observed in any of the patients during the follow-up period. STUDY LIMITATIONS: This is a single-center retrospective study with relatively few patients including only the Turkish population. CONCLUSION: Secukinumab seems to be effective in plaque psoriasis, particularly in bionaive and non-smokers. Moreover, it is safe in patients with inactive hepatitis or tuberculosis.

Prevalence and factors associated with olfactory impairment among patients with acne treated with oral isotretinoin: a cross-sectional study.

OBJECTIVE: This study aimed to investigate the prevalence and factors associated with olfactory dysfunction in individuals exposed to Isotretinoin (ISO) for the treatment of acne, using the University of Pennsylvania Smell Identification Test (UPSIT®). METHODS: This cross-sectional study enrolled age and sex-matched patients with acne who were current users of oral ISO and unexposed controls without olfactory complaints. UPSIT® and a validated questionnaire (Nasal Obstruction Symptom Evaluation) were administered to evaluate nasal obstruction in patients exposed to ISO. RESULTS: A total of seventy patients were recruited, with 35 in the exposed group and 35 in the unexposed group, consisting of 18 males and 17 females in each group, aged from 17 to 47 years. The prevalence of olfactory dysfunction was higher in the exposed group compared to the non-exposed group (62.9% vs. 17.1%), yielding a Prevalence Ratio (PR) of 3.7 (95% CI 1.9-7.1). However, no participants were categorized as anosmia or severe hyposmia and the majority of dysfunction was mild hyposmia compared to moderate hyposmia (51.5% vs. 11.4%). Among the exposed individuals, gasoline, orange, coffee, and wood exhibited the highest rates of identification errors (≥54%). Olfactory function demonstrated a negative correlation with treatment duration (p = 0.01), cumulative dose (p = 0.02), and nasal obstruction (p = 0.02). CONCLUSIONS: Olfactory dysfunction was more prevalent among ISO users, despite the patients being unaware of the disorder. Olfactory changes were correlated with treatment duration, cumulative dose, and nasal obstruction. LEVEL OF EVIDENCE: Level 4.

Unmet need for and impact of adopting immunobiological drugs for moderate to severe plaque psoriasis in a pediatric population.

Palhano et al. demonstrate the feasibility of incorporating secukinumab and ustekinumab into the Clinical Protocol and Therapeutic Guidelines for moderate to severe psoriasis in pediatric patients. OBJECTIVE: Therefore, this study aimed to evaluate the impact of secukinumab and ustekinumab against moderate-to-severe plaque psoriasis in a Brazilian pediatric population with access to public healthcare. METHODS: A survey of immunobiological treatments registered for use against pediatric psoriasis at the National Health Surveillance Agency was conducted. These treatments were compared to the list available in the same treatment category in the public health system through the Clinical Protocol and Therapeutic Guidelines for psoriasis. A quantitative analysis of the data of patients treated with immunobiological drugs the previous year in accordance with the Clinical Protocol and Therapeutic Guidelines was performed using data available in the DATASUS portal. RESULTS: The public budget impact scenarios analyzed were comparable to the investment already planned for acquiring the only available drug option. CONCLUSION: The incorporation of two therapeutic options in the Clinical Protocol and Therapeutic Guidelines list for moderate-to-severe pediatric psoriasis was feasible in a horizon of 5 years compared to the investment into the single option available to pediatric patients. These findings can facilitate the local analysis of budgetary impact and discussions on the feasibility of this therapeutic incorporation at the state level. Incorporation of secukinumab and ustekinumab was economically feasible. These drugs are options for those who do not respond to or have contraindications to etanercept.

Evaluating the Cost Burden of Alopecia Areata Treatment: A Comprehensive Review for Dermatologists.

Alopecia areata (AA) is managed with prolonged medical treatments and cosmetic therapies, whose cost can be burdensome. We sought to identify the costs of AA treatment and consolidate the available data for the practicing dermatologist by performing a PubMed search of articles indexed for MEDLINE. Ten studies including approximately 16,000 patients with AA across a range of Oxford Centre for Evidence-Based Medicine Levels of Evidence were included. Studies showed that despite the limited efficacy of many AA therapies, patients incurred substantial expenses to manage their AA.

Sequential therapy with topical clobetasol for 14 days followed by hydroquinone versus hydroquinone alone in facial melasma treatment: a randomized, double-blind, controlled clinical trial.

BACKGROUND: Clobetasol has demonstrated remarkable results in treating melasma within a short time frame; however, its use is limited because of the risk of local side effects. To date, there is no controlled trial on sequential clobetasol/hydroquinone for melasma. This study aimed to investigate the tolerability and efficacy of 0.05% clobetasol followed by 4% hydroquinone (CLOB-HQ) in comparison to the isolated use of 4% hydroquinone (HQ). METHODS: A double-blinded, randomized clinical trial involving 50 women with facial melasma was performed. They were directed to apply 0.05% clobetasol every night for 14 days, followed by 4% hydroquinone for 46 days (CLOB-HQ group), or the use of hydroquinone for 60 days (HQ group). Evaluations were carried out at inclusion, and after 14 and 60 days of treatment, measuring modified Melasma Area and Severity Index (mMASI), Melasma Quality of Life scale (MELASQoL), and colorimetry. The Global Aesthetic Improvement Scale (GAIS) was assessed by a blinded evaluator. RESULTS: There was no difference in the main outcomes at D14 and D60 (P > 0.1). For CLOB-HQ, the mean (CI 95%) reduction in mMASI was 13.2% (5.1-21.3%) and 43.1% (32.2-54.0%) at D14 and D60, and for HQ, they were 10.6% (5.9-27.5%) and 44.8% (33.2-52.3%). The MELASQoL, colorimetric luminosity, and GAIS showed a progressive improvement for both groups despite no difference between them. No severe side effects were identified. No cases of telangiectasias, atrophy, or perioral dermatitis were associated with the use of CLOB. CONCLUSION: The sequential CLOB-HQ regimen was safe and well tolerated, even though its efficacy was not different from HQ after 14 or 60 days of treatment. Based on these findings, the use of clobetasol 14 days before hydroquinone is not advisable for the treatment of melasma.

Acne treatment challenges - Recommendations of Latin American expert consensus.

BACKGROUND: Acne is a chronic inflammatory disorder of the pilosebaceous unit that is associated with a negative impact on quality of life, causing anxiety, depression, and poor self-esteem. The treatment of acne is not simple and presents some new challenges. This article addresses important issues faced by dermatologists on their daily, some of them specific for Latin America. OBJECTIVE: To discuss daily practice recommendations when managing acne patients. METHODS: A literature review was conducted by a group of eight experts with extensive experience in the field of acne. The results of the data review were presented at an initial kick-off meeting to align the consensus topics. Two e-surveys using the Delphi methodology and an interim group webinar meeting were held. RESULTS: The expert panel reached a consensus on all proposed key statements, providing scientific support to help dermatologists and healthcare providers make acne management decisions on topics that can be challenging in the everyday practice of dermatology, such as the characteristics of Generation Z or the importance of the maintenance phase of adult acne treatment. CONCLUSION: This article provides current recommendations for managing acne patients. The high level of agreement achieved based on the latest evidence supports the best acne therapeutic choices in both established topics and new important issues that have emerged in recent years, such as the impact of social media, Generation Z characteristics, and transgender male patient specifics.

Topical corticosteroids for treating phimosis in boys.

BACKGROUND: This is an updated version of a Cochrane Review first published in 2014. Phimosis is a condition in which the prepuce (foreskin) cannot be fully retracted past the head of the penis (glans). Phimosis is often treated surgically by circumcision or prepuce plasty; however, reports of non-invasive treatment using topical corticosteroids applied for four to eight weeks have suggested favorable outcomes. OBJECTIVES: To assess the effects of topical corticosteroids applied to the stenotic portion of the prepuce for the treatment of phimosis in boys compared with placebo or no treatment. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, LILACS, and ClinicalTrial.gov. We checked reference lists of included studies and relevant reviews for additional studies. There were no restrictions on the language of publication. The date of the last search was 4 October 2023. SELECTION CRITERIA: We included all randomized controlled trials (RCTs) that compared the use of any topical corticosteroid with placebo or no treatment for boys with any type or degree of phimosis. DATA COLLECTION AND ANALYSIS: Two review authors independently selected studies, extracted data related to the review's primary and secondary outcomes, and assessed the studies' risk of bias. We used the random-effects model for statistical analyses and expressed dichotomous outcomes as risk ratios (RRs) with 95% confidence intervals (CIs). We contacted the authors of the primary articles to request details of the study design and specific outcome data. We used GRADE to assess the certainty of evidence on a per-outcome basis. MAIN RESULTS: In this update, we identified two new studies with 111 participants, bringing the total number of included studies to 14 (1459 randomized participants). We found that types of corticosteroids investigated, participant age, degree of phimosis, type of phimosis, and treatment duration varied considerably among studies. Compared with placebo or no treatment, topical corticosteroids may increase the complete resolution of phimosis after four to eight weeks of treatment (RR 2.73, 95% CI 1.79 to 4.16; I² = 72%; 10 trials, 834 participants; low-certainty evidence). Based on 252 complete resolutions per 1000 boys in the control group, this corresponds to 436 more complete resolutions per 1000 boys (95% CI 199 more to 796 more). We downgraded the certainty of the evidence by one level for serious study limitations and by one level for serious inconsistency. Topical corticosteroids may also increase the partial resolution of phimosis at four to eight weeks of treatment compared with placebo or no treatment (RR 1.68, 95% CI 1.17 to 2.40; I² = 44%; 7 trials, 745 participants; low-certainty evidence). Based on 297 partial resolutions per 1000 boys in the control group, this corresponds to 202 more partial resolutions per 1000 boys (95% CI 50 more to 416 more). We downgraded the certainty of the evidence by one level for serious study limitations and by one level for serious inconsistency. We are uncertain of the effect of topical corticosteroids compared to placebo on change in retractability score (standardized mean difference [SMD] -1.48, 95% CI -2.93 to -0.03; I²91%; 2 trials, 177 participants; very low-certainty evidence). We downgraded the certainty of the evidence by one level for serious study limitations, one level for serious heterogeneity, and one level for serious imprecision. Compared with placebo, topical corticosteroids may increase the long-term complete resolution of phimosis six or more months after treatment (RR 4.09, 95% CI 2.80 to 5.97; I² = 0%; 2 trials, 280 participants; low-certainty evidence). Based on 171 long-term complete resolutions per 1000 boys in the control group, this corresponds to 528 more complete resolutions per 1000 boys (95% CI 308 more to 850 more). We downgraded the certainty of the evidence by one level for serious study limitations and by one level for serious imprecision. There may be little or no difference in the risk of adverse effects between topical corticosteroids and placebo or no treatment (RR 0.28, 95% CI 0.03 to 2.62; I² = 22%; 11 trials, 1091 participants; low-certainty evidence). Only two of 11 studies that recorded adverse effects reported any adverse effects; one event occurred in the corticosteroid group and six in the control group. We downgraded the certainty of the evidence by one level for serious study limitations and by one level for serious imprecision. AUTHORS' CONCLUSIONS: Topical corticosteroids, compared to placebo or no treatment, may increase complete and partial resolution of phimosis when assessed after four to eight weeks of treatment, and may increase long-term complete resolution of phimosis assessed six or more months after treatment. Topical corticosteroids may have few or no adverse effects, and we are uncertain about their effect on retractability scores. The body of evidence is limited by poor reporting of methods in the studies, important clinical heterogeneity, and serious imprecision in the results. Future, higher-quality trials with long-term follow-up would likely improve our understanding of the effects of topical corticoids on phimosis in boys.

Effects of oral isotretinoin treatment for acne vulgaris patients on anger responses and the relationship with temperament.

OBJECTIVE: Isotretinoin is the only medication against all the factors involved in acne vulgaris pathogenesis. The aim of our study was to verify whether patients with acne vulgaris receiving isotretinoin therapy exhibit elevated anger levels and to observe the correlation between age, temperament traits, and anger. METHODS: The study group comprised a sum of 100 cases, involving 50 individuals with acne vulgaris-required high-dose retinol therapy and 50 controls who did not start any medication. RESULTS: Our study showed that anger levels increased with drug use. A positive correlation between cyclothymic temperament, the anxiety-related behavior subdimension, and the introvert and passive-aggressive subdimension of interpersonal anger reactions has been recognized. In addition, a positive one was observed between hyperthymic temperament and the introvert subdimension, which is one of the anger-related thoughts and interpersonal anger reactions. CONCLUSION: This study elucidates anger dimensions such as anger-related thoughts, behaviors, and reactions in individuals who received retinol treatment for acne vulgaris. In addition to anger and its dimensions, temperament was also investigated. Although several studies have investigated the relationship between acne vulgaris and psychiatric symptoms, to the best of our knowledge, no research has been reported in the English-language literature regarding the relationship between anger dimensions and temperament after retinol treatment that might make our study an original and valuable contribution to the literature.

Antiviral Evaluation of New Synthetic Bioconjugates Based on GA-Hecate: A New Class of Antivirals Targeting Different Steps of Zika Virus Replication.

Re-emerging arboviruses represent a serious health problem due to their rapid vector-mediated spread, mainly in urban tropical areas. The 2013-2015 Zika virus (ZIKV) outbreak in South and Central America has been associated with cases of microcephaly in newborns and Guillain-Barret syndrome. We previously showed that the conjugate gallic acid-Hecate (GA-FALALKALKKALKKLKKALKKAL-CONH2)-is an efficient inhibitor of the hepatitis C virus. Here, we show that the Hecate peptide is degraded in human blood serum into three major metabolites. These metabolites conjugated with gallic acid were synthesized and their effect on ZIKV replication in cultured cells was evaluated. The GA-metabolite 5 (GA-FALALKALKKALKKL-COOH) was the most efficient in inhibiting two ZIKV strains of African and Asian lineage at the stage of both virus entry (virucidal and protective) and replication (post-entry). We also demonstrate that GA-metabolite 5 does not affect cell growth after 7 days of continuous treatment. Thus, this study identifies a new synthetic antiviral compound targeting different steps of ZIKV replication in vitro and with the potential for broad reactivity against other flaviviruses. Our work highlights a promising strategy for the development of new antivirals based on peptide metabolism and bioconjugation.

One Year Into Dupilumab: Physician and Patient Experiences in Initiating Dupilumab for Pediatric Eosinophilic Esophagitis.

In 2022, the US Food and Drug Administration approved dupilumab for treatment of eosinophilic esophagitis (EoE). The aims of this study were to report physician and patient perspectives on initiating dupilumab. A 2-pronged approach was used: (1) data on physician prescribing practices was gathered via retrospective chart review of EoE patients prescribed dupilumab and (2) pediatric patients on dupilumab were approached to complete a questionnaire regarding reasons for initiation. During this time, 42 patients were prescribed dupilumab. From the physician's perspective, the primary reasons for dupilumab included nonresponse to topical corticosteroids (TCS) (52%), nonadherence (28%), adverse effects (10%), or to treat multiple atopic diseases (5%). The median dupilumab initiation time, from day prescribed to first injection, was 37 days [interquartile range (IQR) 37]. Almost all required prior authorization (PA) (98%), while 17% required letter of appeal and 2% required peer-to-peer. Fifteen patients (36%) completed the questionnaire portion of the study. From the patient's perspective, the primary reasons for dupilumab initiation included nonresponse to TCS (27%), nonadherence to TCS (27%), concern about adverse effects of TCS (7%), and treatment of multiple atopic diseases (33%). In conclusion, physicians are prescribing dupilumab primarily for nonresponse to TCS and almost all required PA with a long delay to starting dupilumab.

Acne characteristics in Latin American patients and the potential role of trifarotene.

BACKGROUND: Individualization of treatment based on acne type and severity, location, disease burden, and patient preference is required to maximize efficacy, safety, and adherence to therapy. Latin American populations have unique attributes that must be considered as part of this process to improve clinical success and achieve patient goals. Acne is more common among patients with darker skin phototypes, in whom it is often associated with postinflammatory hyperpigmentation and scarring-the most important acne sequelae-potentially due to more frequent and more severe underlying inflammatory processes in this population. DISCUSSION: These data argue for an early and proactive approach to managing acne in these patients with agents that target the inflammatory processes that underlie acne and its sequelae. As a class, retinoids offer a spectrum of activity that may be useful in addressing the unique needs of Latin American populations. CONCLUSION: Trifarotene, a novel, selective retinoid, has been evaluated in relevant patient populations.

Objective: the present study aims to gather care recommendations considering the prevention and treatment of skin lesions induced by treatment with antineoplastic chemotherapy, according to current studies and consensus. Methodology: a bibliographical study was carried out to survey the relationships between the main antineoplastic drugs and their dermatological intercurrences, as well as their respective management, to subsidize the guidance and counselling of health professionals who treat cancer patients. Result: the main dermatological problems arising from the use of antineoplastic agents correspond to skin lesions, such as discoloration, hyperpigmentation, photosensitivity, erythema, scaling and pruritus. Adverse effects that affect hair and body hair are also recurrent, resulting in alopecia, and the modification of growth and lesions on the nails. Specific treatments for each case can alleviate or reverse the problems. Conclusion: adverse drug reactions involving chemotherapy are frequent in oncology practice, and vary in terms of frequency and severity, affecting various skin appendages. Proper management of these effects improves the integrity of the skin and other structures, providing these patients with improved self-esteem and quality of life.

The usefulness of a dermocosmetic containing Myrtus communis extract and azelaic acid for maintenance phase of adult female acne: Results from a randomized exploratory investigator-blinded comparative study.

BACKGROUND: Acne is a very common condition. Currently, there are relatively few studies available to help guidance-based decisions for its long-term management, especially studies with cosmetic care products. We have developed a skin care product dedicated to adult female acne. OBJECTIVES: Evaluate the efficacy and tolerance of the test product containing Myrtus communis extract and azelaic acid compared with a light moisturizing cream (LCM) in adult females in the acne maintenance phase. METHODS: A clinical study was conducted as a Brazilian, multicentre, randomized, investigator-blinded trial in adult females with clear or almost clear facial acne after anti-acne treatment. The test group (26 subjects) applied the test product and the comparative product group (27 subjects) applied LCM. Both groups applied the products twice daily on the whole face. Subjects were evaluated every 4 weeks over 16 weeks. Efficacy was evaluated according to acne relapse; Investigator's Global Assessment (IGA); acne lesions counting; AcneQoL questionnaire; Subject Global change Assessment (SGA) of acne severity; and the number of Post-Inflammatory Hyperpigmentation (PIH) and Post-Inflammatory Erythema (PIE) lesions. Tolerance was assessed according to a 5-point scale. RESULTS: Over 16 weeks, the number of acne relapse was more than double in the comparator compared to the test product group (eight subjects vs. three subjects respectively). There was no statistical difference in the evolution of the mean IGA from baseline between the two groups; however, 85% of subjects were assessed as clear or almost clear in the test product group and 67% in the comparative group. CONCLUSIONS: This study demonstrated the effectiveness topical application of the test product compared to LCM on acne severity in the maintenance phase of adult female acne. Efficacy results after 16 weeks suggested a trend to limit acne relapses and a benefit of the test product in maintaining long-term remission.
