[PMID: 38735650 DOI: 10.1080/09546634.2024.2324833] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Accepted: 02/23/2024] [Indexed: 05/14/2024]
Abstract
BACKGROUND Lebrikizumab, a high-affinity monoclonal antibody targeting IL-13, previously demonstrated clinical efficacy in three randomized, double-blind, placebo-controlled Phase 3 trials that included adults and adolescents with moderate-to-severe atopic dermatitis (AD): ADvocate1, ADvocate2, and ADhere. AIM This subset analysis evaluated 16-week physician- and patient-reported outcomes of lebrikizumab in the adolescent patients enrolled in these three trials. METHODS Eligible adolescents (≥12 to <18 years weighing ≥40kg) were randomized 2:1 to subcutaneous lebrikizumab (500 mg loading doses at baseline and Week 2 followed by 250 mg every 2 weeks) or placebo as monotherapy in ADvocate1&2, and in combination with topical corticosteroids (TCS) in the ADhere study. Week 16 analyses included clinical efficacy outcomes (IGA (0,1) with ≥2-point improvement, EASI 75, EASI 90), patient-reported Pruritus NRS ≥4-point improvement and Sleep-Loss Scale ≥2-point improvement. RESULTS Pooled ADvocate1&2 16-week results in lebrikizumab (N = 67) vs placebo (N = 35) were: IGA (0,1) 46.6% vs 14.3% (p < 0.01), EASI 75 62.0% vs 17.3% (p < 0.001), EASI 90 40.7% vs 11.5% (p < 0.01), Pruritus NRS 48.9% vs 13.1% (p < 0.01), and Sleep-Loss Scale 26.9% vs 6.9% (p = 0.137). Corresponding results for ADhere, (lebrikizumab + TCS, N = 32; placebo + TCS, N = 14), were consistent. CONCLUSIONS Lebrikizumab treatment demonstrated efficacy in improving the signs and symptoms of AD in adolescent patients, consistent with the ADvocate and ADhere overall population results.

Abstract
Background Atopic dermatitis (AD) is an inflammatory skin condition, often multifactorial in origin, and most commonly manifests during childhood. Although there remains a deficit in literature, current data suggest Honduras may have the highest prevalence and severity of AD among all Latin American countries. Objective To assess the current prevalence of pediatric AD in Honduras and evaluate existing gaps in available literature to monitor disease burden. Methods A comprehensive literature search was performed in March 2023. Articles were removed if they were published before 2007, were of the incorrect study design, or were focused on countries outside of Honduras. The articles were independently reviewed by 2 authors. Results The initial literature search yielded 174 studies, of which 7 met inclusion criteria. AD prevalence rates in children in Honduras ranged from 0.7% to 40.0%. Limitations Limitations include elements of study design, analytic methods, study populations, and limited articles. Conclusion There appears to be a disproportionately higher prevalence and disease burden of pediatric AD in Honduras. Future research should acquire accurate data to further understand the prevalence, incidence, and severity of AD in Honduras.

Atopic Dermatitis in Latin America: Considerations on Epidemiology, Clinical and Laboratory Features, Ethnic/Racial Variations, and Therapeutic Management. J Clin Med 2023; 12:jcm12103419. [PMID: 37240525 DOI: 10.3390/jcm12103419] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2023] [Revised: 05/05/2023] [Accepted: 05/10/2023] [Indexed: 05/28/2023] Open
Abstract
Latin America (LA) encompasses about 8.5% of the world's population, exhibits ethnic/racial heterogeneity and social inequality. We hereby present a 20-year literature review (2004-2023) on epidemiology, diagnosis, clinical and laboratory features, quality of life and management of atopic dermatitis (AD) in LA. Highest AD prevalence for children aged 6-7 years was reported in Ecuador (22.5%) and Colombia (20.9%), for adolescents in Colombia (24.6%) and for all ages, in Brazil (20.1%). Regions with a predominantly Black population in LA varied significantly, ranging from 4.4% in Northern Brazil to 10.1% in Cuba, indicating genetic variation among African subgroups. Filaggrin loss-of-function mutations showed variants seen in Europeans in 9.3% of Chilean patients and studies in Brazil revealed impaired expression of filaggrin and claudin-1 in the skin but increased expression in conjunctival epithelia of AD patients. The most reported AD features included erythema, pruritus, and dry skin, with marked lichenification. Severe pruritus was reported by 54.4% of patients and a high impact on quality of life was detected in 50% of adults with AD. In Brazilian referral hospitals, 65.6% of patients were classified as having severe AD, and 56% had one or more hospitalizations during their lifetime, indicating a need for better disease control. Diagnosing AD is challenging due to broad clinical features, ethnoracial variations and lack of universal diagnostic criteria. Furthermore, lack of physician training, barriers to medication access, and socioeconomic inequalities hinder effective disease management in LA.

Multimorbidity of Allergic Conditions in Urban Citizens of Southern China: A Real-World Cross-Sectional Study. J Clin Med 2023; 12:jcm12062226. [PMID: 36983228 PMCID: PMC10059830 DOI: 10.3390/jcm12062226] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Revised: 02/15/2023] [Accepted: 03/02/2023] [Indexed: 03/15/2023] Open
Abstract
Background: Extensive knowledge of allergic multimorbidities is required to improve the management of allergic diseases with the industrialization of China. However, the demography and allergen distribution patterns of allergic multimorbidities in China remain unclear, despite the increasing prevalence of allergies. Methods: This was a real-world, cross-sectional study of 1273 outpatients diagnosed with one or more allergic diseases in Guangzhou, the most populated city of southern China, with leading industrial and commercial centers, between April 2021 and March 2022. Seven allergic diseases (allergic rhinitis (AR), asthma (AS)/cough variant asthma (CVA), atopic dermatitis (AD)/eczema, food allergy (FA), allergic conjunctivitis (AC), drug allergy (DA), and anaphylaxis) were assessed. Positive rates of sensitization to different allergens were measured using an allergen detection system of the UniCAP (Pharmacia Diagnostics, Sweden) instrument platform to compare the groups of allergic multimorbidities against a single entity. Results: There were 659 (51.8%) males and 614 (48.2%) females aged from 4 months to 74 years included in the analysis. The study participants who were diagnosed with allergic diseases had an average of 1.6 diagnoses. Overall, 46.5% (592 of 1273) of the patients had more than one allergic condition, and allergic rhinitis was the most common type of multimorbidity. Women were more likely to suffer from an allergic disease alone, whereas allergic multimorbidities were more likely to be diagnosed in men (p = 0.005). In addition, allergic multimorbidities were common in all age groups, with an incidence ranging from 37.1% to 57.4%, in which children and adolescents were more frequently diagnosed with allergic multimorbidities than adults (18–60 years old) (all p < 0.05). Allergic multimorbidity was observed throughout the year. A difference in the positive rate of allergens sensitization and total immunoglobulin E (tIgE) levels between different allergic multimorbidities was observed. Conclusions: Allergic multimorbidities were very commonly found in nearly half of all patients with allergies. The proportion of allergic multimorbidities varied with the type of disease, sex, age, and allergen distribution pattern. These findings may help clinicians to develop “One health” strategies for the clinical management of allergic diseases.

Abstract
BACKGROUND Severity-associated factors in atopic dermatitis (AD) have focussed on early onset, concomitant atopic diseases, markers of Th2-shifted inflammation and filaggrin mutations. OBJECTIVES To investigate factors associated with severe AD in Finnish patients. METHODS We conducted a single-centre, cross-sectional observational study with 502 AD patients aged 4.79 to 79.90 years (mean 32.08 years). Disease severity was assessed with the Rajka-Langeland severity score and EASI and associated clinical signs were evaluated. Data regarding onset, relatives, atopic and other comorbidities was gathered retrospectively. We investigated total serum IgE-levels, a panel of filaggrin null mutations and functional variants of genes associated with skin barrier defects. RESULTS Factors more frequent in severe AD included early onset (P = 0.004, 95%CI 0.000-0.024), male sex (P = 0.002, 95%CI 0.000-0.11), history of smoking (P = 0.012, 95%CI 0.000-0.024), concomitant asthma (P = 0.001, 95%CI 0.000-0.011), palmar hyperlinearity (P = 0.013, 95%CI 0.014-0.059), hand dermatitis (P = 0.020, 95%CI 0.000-0.029) and history of contact allergy (P = 0.042, 95%CI 0.037-0.096). Body mass indices (P < 0.000, 95%CI 0.000-0.011) and total serum IgE-levels (P < 0.000, 95%CI 0.000-0.011) were higher in severe AD. No differences were observed for allergic rhinitis, allergic conjunctivitis, food allergy, peanut allergy, prick positivity, keratosis pilaris, history of herpes simplex infections, filaggrin null mutations and other gene variants. CONCLUSIONS Severity determinants in Finnish patients seem to be early-onset, male sex, smoking, overweight, concomitant asthma, palmar hyperlinearity, hand dermatitis and high IgE-levels. A sub-typing of patients in relation to confirmed severity determinants may be useful for course prediction, prognosis and targeted AD management.

Wang S, Wang Y, Han B, Chen Y, Bai X, Yu S, Liu M. Huanglian ointment alleviates eczema by maintaining the balance of c-Jun and JunB and inhibiting AGE-RAGE-mediated pro-inflammation signaling pathway. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 105:154372. [PMID: 35932609 DOI: 10.1016/j.phymed.2022.154372] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/27/2022] [Revised: 07/22/2022] [Accepted: 07/31/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Huanglian ointment exhibits clinical efficacy for repairing skin barriers and inhibiting skin inflammation, and has been used to ameliorate eczema for many years. However, the active components and mechanism of Huanglian ointment have not yet been elucidated. PURPOSE This study aimed to demonstrate the main active components and molecular mechanisms of Huanglian ointment for the treatment of eczema. METHODS The main active components of Huanglian ointment were identified by gas chromatography-mass spectrometry. Network pharmacology approach and molecular docking techniques to predict the potential molecular mechanisms of Huanglian ointment alleviating eczema. Furthermore, Biostir-AD®-induced guinea pigs and tumor necrosis α (TNF-α)/interferon γ (IFN-γ)-induced HaCaT cells were employed to investigate the effectiveness and mechanisms of Huanglian ointment using histopathological staining, enzyme-linked immunosorbent assay, MTT assay, and western blot analysis. RESULTS Fourteen chemistry components were identified in Huanglian ointment. In total, 78 intersecting gene targets were identified between Huanglian ointment and eczema, including Jun, inflammatory regulators, and chemokine factors. Intersecting gene targets were enriched for cytokine and chemokine receptor binding, and inflammatory related signaling pathways. The molecular docking results showed that the identified components had a stable binding conformation with core targets. In vivo experiments showed that Huanglian ointment markedly ameliorated eczema-like skin lesions, restored histopathological morphology, and decreased levels of TNF-α, IFN-γ, and interleukin 6. Moreover, Huanglian ointment effectively protected HaCaT cells against TNF-α/IFN-γ-induced cell death and overproduction of thymus- and activation-regulated chemokine, macrophage-derived chemokine, and regulated upon activation normal T cell-expressed and secreted factor. Subsequently, we found that Huanglian ointment repaired skin barriers by affecting c-Jun, JunB, and filaggrin expression, and suppressed inflammatory response by inhibiting AGE-RAGE signaling pathway, both in vivo and in vitro. CONCLUSION Our results demonstrated that Huanglian ointment repaired skin barriers and inhibited inflammation by maintaining the balance of c-Jun and JunB, and suppressing AGE-RAGE signaling pathway, thereby relieving eczema. These findings providing a molecular basis for treatment of eczema by Huanglian ointment.
