Off-label use of Baricitinib improves moderate and severe atopic dermatitis in China through inhibiting MAPK and PI3K/Akt/mTOR pathway via targeting JAK-STAT signaling of CD4 + cells. Front Pharmacol 2024; 15:1324892.

Abstract
As an inflammatory disease with a disrupted immune system, cytokine disorders in atopic dermatitis (AD) are closely related to the abnormal activation of JAK-STAT signal pathway. The critical relevance of the JAK-STAT signaling pathway to the pathogenesis of AD provides a strong rationale for JAK inhibitor research. Baricitinib, a small-molecule oral JAK inhibitor, has been proven to inhibit JAK-STAT signaling in a variety of diseases, including AD. It is currently available in China for off-label use. However, its efficacy in China and its mechanism are rarely reported. In our study, we found that the immune status of patients with moderate and severe AD was hyperactive. Among the 49 known immunotherapy targets, JAK1 and JAK2 genes on lymphocytes of AD patients were significantly upregulated, which was closely related to the symptom severity in moderate and severe AD patients. Baricitinib can improve immune hyperresponsiveness and clinical symptoms in moderate and severe AD by inhibiting the activation of Th2 cell subsets and the secretion of Th2-type cytokines through MAPK, mTOR and PI3K-Akt signaling pathways, providing an important theoretical basis for clinical off-label use of Baricitinib to treat moderate and severe AD.

Abstract
Purpose Data specific to the epidemiology, clinical features, and management of chronic urticaria (CU) in the geriatric population remain limited and not well understood. We aim to systematically review the prevalence, clinical manifestations, treatment, and clinical course of elderly patients with CU. Patients and methods Original articles that included data of elderly (aged >60 years) with CU that were published until February 2021 were searched in PubMed, Scopus, and Embase using predfefined search terms. Related articles were evaluated according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations. Results Among the included 85 studies and 1,112,066 elderly CU patients, most (57.4%) were women. The prevalence of elderly CU in the general population ranged from 0.2–2.8%, and from 0.7–33.3% among all CU patients. Compared to adult CU, elderly CU patients had a higher percentage of wheal alone (73.9%), and lower rate of positive autologous serum skin test and atopy. Gastrointestinal diseases were the most common comorbidity (71.9%), and there was a high rate of malignancies and autoimmune diseases. Second generation H1-antihistamines were commonly used, and achievement of complete control was most often reported. Omalizumab was prescribed in 59 refractory patients, and a significant response to treatment was reported in most patients. The treatment of comorbidities also yielded significant improvement in CU. Conclusion Elderly CU was found to be different from adult CU in both clinical and laboratory aspects. H1- antihistamines are effective as first-line therapy with minimal side-effects at licensed doses. Treatment of secondary causes is important since the elderly usually have age-related comorbidities.

Abstract
Omalizumab is the first monoclonal antibody that was globally approved as a personalized treatment option for patients with moderate-to-severe allergic asthma. This review summarizes the knowledge of almost two decades of use of omalizumab to answer some important everyday clinical practice questions, concerning its efficacy and safety and its association with other asthma-related and drug-related parameters. Evidence suggests that omalizumab improves asthma control and reduces the incidence and frequency of exacerbations in patients with severe allergic asthma. Omalizumab is also effective in those patients in reducing corticosteroid use and healthcare utilization, while it also seems to improve lung function. Several biomarkers have been recognized in predicting its efficacy in its target group of patients, while the optimal duration for evaluating its efficacy is between 16 and 32 weeks.

Abstract
Asthma is considered a syndrome composed of heterogeneous disorders involving complex chronic airway inflammation. Patients with severe asthma, prolonged symptoms, and frequent asthma exacerbations, despite high doses of inhaled corticosteroids, may benefit from treatment with biologics. Four types of biologics are available for severe asthma, including an anti-immunoglobulin E (IgE) antibody (omalizumab), anti-interleukin (IL)-5 antibody (mepolizumab and reslizumab), anti-IL-5 receptor α antibody (benralizumab), and anti-IL-4 receptor α antibody (dupilumab). Biologics for patients with severe asthma demonstrate high therapeutic efficacy and provide significant clinical benefits, including the prevention of asthma exacerbations, alleviation of symptoms, improvement in the quality of life and respiratory function, and reduction in frequencies of hospitalization and emergency outpatient visits. This review provides an overview of the modulation of immunological features by each of the four established biologics in patients with severe allergic asthma. Given the extensive immunomodulatory effects of biologics, further analyses of their precise effects on the human immune system are warranted.

Abstract
Immunoglobulin E (IgE) plays an essential role in many allergic diseases. This review highlights the role of IgE in atopic dermatitis (AD), a common, chronic, and complex skin inflammation, and the available therapeutic approaches that target IgE in AD. We examine the existing data showing the use of omalizumab, the only biologic anti-IgE therapy available in clinical use, plasma apheresis, and a combination of both therapeutic approaches for the treatment of AD. Existing data on the efficacy of omalizumab in AD are inconclusive. A limited number of randomised controlled studies, few uncontrolled prospective and retrospective reports, as well as multiple case series and case reports observed varying degrees of the efficacy of omalizumab in AD. Omalizumab displays a trend of higher efficacy in AD patients with low IgE levels compared with those with very high-to-extremely high serum IgE concentrations. Plasma apheresis and its combination with omalizumab show good efficacy, even in patients with unusually high serum IgE concentrations. Combining apheresis and anti-IgE treatment may serve as a comprehensive therapeutic approach for patients with elevated levels of IgE. Dedicated clinical studies with robust study designs are needed to establish the therapeutic efficacy of omalizumab in AD.

Abstract
Chronic spontaneous urticaria (CSU) is defined as the spontaneous development of itchy hives and/or angioedema due to known or unknown causes that last for at least 6 weeks. At any given time, CSU is believed to affect 0.5–1% of the global population. Omalizumab (a recombinant, humanized anti-immunoglobulin-E antibody) is the only approved treatment for antihistamine refractory CSU. However, ~ 30% of patients remain symptomatic at licensed doses of omalizumab 150 mg and 300 mg, even after a treatment period of over 6 months. In the recent years, there have been several studies on updosing of the drug, suggesting that the individualized approach for urticaria treatment with omalizumab is useful. In this article, we provide an overview of these studies and the real-world data on omalizumab updosing as it became necessary to obtain complete CSU symptom control in a proportion of patients. Published observational studies (from June 2003 to October 2019) on the updosing of omalizumab in CSU were identified using PubMed and Ovid databases. Reports mainly show that updosing/dose adjustment evaluated with the assessment of disease activity (Urticaria Activity Score) and control (Urticaria Control Test) achieves better clinical response to omalizumab with a good safety profile in a pool of patients with CSU. These real-world data will provide an overview of updosing of omalizumab in CSU and aid in setting informed clinical practice treatment expectations.

From regulatory limitations to new opportunities: Real-life experience on the effectiveness of short courses of omalizumab in the treatment of chronic idiopatic urticaria.

Abstract
Economic sustainability of long-term continuous treatment of antihistamine refractory chronic urticaria with omalizumab may be an issue. We assessed the efficacy of relatively short courses (5-6 months) of omalizumab in patients with chronic idiopathic urticaria (CIU). We retrospectively studied 40 patients (observed between June 2015 and January 2019) affected by moderate-to-severe CIU refractory to anti-H1 antihistamines (up to fourfold doses). Omalizumab was administered every 4 weeks for 24 weeks, then for 20 weeks in case of a relapse of moderate-to-severe degree, then again for 24 weeks in case of a second relapse. Monthly clinical evaluations were performed. Mean disease severity significantly dropped after 1 month and further decreased thereafter, with 30 complete remissions after the first course of treatment. In 2-4 months, 18 patients had a relapse of moderate-to-severe degree. The profile of response to the second course of omalizumab was similar to the first. A third course was necessary for seven patients. No adverse effects were recorded. Courses of 5-6 months of omalizumab may induce rapid significant improvement of urticaria and many prolonged complete remissions. In case of relapse, further courses show a similar profile of response and may induce additional long-term complete remissions.

Abstract
Importance Omalizumab is indicated for the management of chronic idiopathic urticaria (CIU) (also known as chronic spontaneous urticaria) in adolescents and adults with persistent hives not controlled with antihistamines. The effectiveness of omalizumab in the real-world management of CIU is largely unknown. Objective To quantitatively synthesize what is known about the benefits and harms of omalizumab in the real-world clinical management of CIU regarding urticaria activity, treatment response, and adverse events. Data Sources Published observational studies (January 1, 2006, to January 1, 2018) and scientific abstracts on the effectiveness of omalizumab in CIU were identified using PubMed, Embase, Web of Science, and Cochrane search engines; references were searched to identify additional studies. Study Selection Included studies were observational in design and included at least 1 outcome in common with other studies and at a concurrent time point of exposure to omalizumab. A total of 67 articles (35.2% of those screened) were included in the analysis. Data Extraction and Synthesis PRISMA and MOOSE guidelines were followed; independent selection and data extraction were completed by 2 observers. Random-effects meta-analyses were performed. Main Outcomes and Measures Main outcomes were change in weekly Urticaria Activity Score (UAS7; range, 0-42), change in Urticaria Activity Score (UAS; range 0-6) (higher score indicating worse outcome in both scales), complete and partial response rates (percentages), and adverse event rate (percentage). Results Omalizumab therapy was associated with an improvement in UAS7 scores (-25.6 points, 95% CI, -28.2 to -23.0; P < .001; 15 studies, 294 patients), an improvement in UAS scores (-4.7 points, 95% CI, -5.0 to -4.4, P < .001; 10 studies, 1158 patients), an average complete response rate of 72.2% (95% CI, 66.1%-78.3%; P < .001; 45 studies, 1158 patients) with an additional average partial response rate of 17.8% (95% CI, 11.7%-23.9%; P < .001; 37 studies, 908 patients), and an average adverse event rate of 4.0% (95% CI, 1.0%-7.0%; P < .001; any level of severity, 47 studies, 1314 patients). Conclusions and Relevance Benefits and safety of omalizumab in the real-world treatment of CIU meet or exceed results gleaned from clinical trials. These real-world data on omalizumab in CIU may help inform both clinical treatment expectations and policy decision making.

Abstract
INTRODUCTION Omalizumab, has been used for almost two decades, mainly in allergic asthma and chronic spontaneous urticaria for which it is highly beneficial. Smaller studies have evaluated the effects of omalizumab in atopic dermatitis (AD). Current treatments options, such as cyclosporine and azathioprine have limited effect on AD and numerous side effects. The recently introduced biologic dupilumab (anti-IL4) shows promising results, however with conjunctivitis as a prevalent side effect. We evaluate the current evidence for the use of omalizumab in AD. EVIDENCE ACQUISITION Systematic literature searches were performed in PubMed, Web of Science, Embase and Clinicaltrials.gov to identify any study (case reports, case series, and controlled trials) evaluating the effect of treatment with omalizumab in AD. EVIDENCE SYNTHESIS Thirty-four studies (12 single case studies, 15 case series, 5 prospective studies and 2 small pilot randomized placebo-controlled trials [RCTs]), including a total of 214 patients with median of 3, ranging from 1-35 patients were identified. A total of 169 patients (79.0%) experienced a beneficial effect from treatment, ranging from little to complete response, whereas 45 patients (21.0%) reported no or negative effect from omalizumab treatment. CONCLUSIONS Omalizumab is a safe and well-tolerated treatment with some clinical benefit in AD patients. However, the lack of larger RCTs and possible publication bias limit the recommendation of omalizumab for use in clinical practice for AD. Newer and more effective treatments exist and should be prioritized.

Abstract
Severe atopic dermatitis, which affects both adults and children, is a debilitating disorder with a significant decline of patients' quality of life. Although aetiopathogenic factors are currently a topic of study and interpretation, the main features of atopic eczema are skin barrier disturbance and immune dysregulation. Severe refractory disease that fails to improve with conventional therapy may benefit from biologic therapy. Progress in understanding immunopathology of atopic dermatitis have allowed identification of therapeutic molecular targets in the field of biological therapy. We reviewed the different biological treatments with a focus on novel targeted agents: Systemic immunotherapy (Omalizumab, Dupilumab, Lebrikizumab, Tralokinumab, Nemolizumab, Ustekinumab, Fezakinumab, Tezepelumab, Apremilast, allergen specific immunotherapy), and topical agents (Tofacitinib, Crisaborole).

Abstract
RATIONALE Atopic dermatitis is a frequent, relapsing, chronic inflammatory skin condition with a deep negative impact on quality of life. Three are the major pathological factors driving its complex pathogenesis: the skin barrier disruption, the altered Th2 cell response and itching. Current management of the disease is often unsatisfactory, unable to induce a complete resolution of signs and symptoms or at least a significant clinical improvement with adequate patient satisfaction. PATIENT CONCERNS We report the case of a 57-year-old man with severe chronic atopic dermatitis for at least 40 years irresponsive to traditional therapies. The patient was treated in the past with different standard therapeutic regimens without satisfactory and lasting results. DIAGNOSES The diagnosis of AD was based on the revised criteria of Hanifin and Rjika and the Scoring Atopic Dermatitis was assessed together with laboratory evaluation. INTERVENTIONS He received off-label omalizumab (300 mg subcutaneous injection repeated at 2-week intervals for six months). OUTCOMES Scorad and laboratory findings were assessed montly and demonstrated a progressive decrease (SCORAD and ECP levels) togheter with general clinical improvement. Omalizumab, in our patient, determined a significant symptomatic improvement, assessed by SCORAD, simultaneously with a progressive decline in ECP serum levels, whit no side effects, confirming the substantial safety of the drug. LESSONS The satisfactory response to omalizumab after the failure of all previous traditional treatments, confirms the efficacy of this biological drug in the therapy of refractory AD with high IgE levels and increased ECP serum levels. The lesson learnt from this case report is that Omalizumab represent an effective and safe alternative to traditional therapies in patients with severe irresponsive atopic dermatitis.

Abstract
Introduction Peripheral neuropathy (PN) is a common neurological condition causing symmetrical and diffuse damage in nerves. The etiology of PN includes systemic diseases, toxic exposure, medications, infections, and hereditary diseases. Omalizumab is a humanized monoclonal anti-IgE antibody that exerts its activity by binding to free IgE in circulation. Aim To investigate the relationship between omalizumab and peripheral neuropathy. Material and methods The study included 30 patients who underwent omalizumab therapy (Xolair) due to the diagnosis of chronic urticaria. A detailed neurological and physical examination was performed in each patient both before and 3 months after the therapy. Electrophysiological examination was also performed using a Medelec Synergy instrument. Results The 30 patients included 8 (26.7%) men and 22 (73.3%) women with a mean age of 37.5 ±14.14 years. No serious side effect of the medication was detected in any patient although local wound irritation occurred in 3 (10%) patients. Moreover, no change occurred in the pre-treatment Neuropathy Symptom Score (NSS) or Neurological Disability Score (NDS) of the patients and no pathological values that could result in neuropathy were observed during motor/sensory nerve conduction. However, significant changes were detected in the sensory and motor components of the nerves with regards to pre- and post-treatment values. Conclusions Omalizumab therapy caused no peripheral neuropathy in any of our patients but altered the latency, amplitude, and velocity values of the peripheral nerves.

Abstract
INTRODUCTION Chronic idiopathic/spontaneous urticaria (CIU/CSU) is a dermatological condition characterized by itchy wheals and/or angioedema of continuous or intermittent duration of ≥6 weeks with a high burden of disease and impact on quality of life. Omalizumab is a recombinant humanized monoclonal antibody that inhibits the binding of IgE to high affinity receptors, and is approved for the CIU/CSU indication. The objective of this systematic review was to evaluate and synthesize the evidence on the real-world effectiveness of omalizumab in CIU/CSU in daily clinical practice. AREAS COVERED This review of 84 observational effectiveness studies covers treatments (dosing, medication use), clinical outcomes (treatment response, disease activity, quality of life), and safety. EXPERT OPINION The clinical outcomes observed across studies underscore the real-world effectiveness of omalizumab in the management of CIU/CSU. Continued treatment may assist patients showing an initial response to achieve a complete treatment response. Response rates are aligned with observed changes in disease activity, symptom experience, and quality of life, and this across subtypes of CIU/CSU. The positive therapeutic profile is complemented by a positive safety profile. The real-world evidence summarized here points convincingly at the high degree of effectiveness of omalizumab in the treatment of CIU/CSU in daily clinical practice.

Abstract
Chronic spontaneous urticaria (CSU) is a mast cell-driven disease that is defined as the recurrence of weals, angioedema or both for > 6 weeks due to known or unknown causes. As of yet, disease diagnosis is purely clinical. Objective tools are needed to monitor the activity of CSU and the efficacy of treatment. Recently, several reports have suggested that blood parameters may be considered as potential disease-related biomarkers. Here, we reviewed available literature on blood biomarkers for CSU diagnosis, activity monitoring, duration, patient subgroup allocation or response to treatment. We performed a PubMed, Google Scholar and Web of Science search and identified and analysed 151 reports published prior to January 2016. We found strong evidence for significant differences between patients with CSU and healthy controls in blood levels or values of D-dimer, C-reactive protein (CRP), matrix metalloproteinase-9 (MMP-9), mean platelet volume (MPV), factor VIIa, prothrombin fragment 1 + 2 (F1 + 2), tumour necrosis factor, dehydroepiandrosterone sulphate and vitamin D. Also, there is strong evidence for a significant association between CSU activity and blood levels or values of D-dimer, F1 + 2, CRP, IL-6 and MPV. Strong evidence for reduced basophil count and high levels of IgG anti-FcεRI in the subgroup of CSU patients with positive autologous serum skin test was shown. In contrast, the evidence for all reported blood biomarkers for differentiating CSU from other diseases, or a role in prognosis, is weak, inconsistent or non-existent. Taken together, we identified 10 biomarkers that are supported by strong evidence for distinguishing patients with CSU from healthy controls, or for measuring CSU activity. There is a need for further research to identify biomarkers that predict outcome or treatment response in CSU.

Abstract
Therapeutics of autoimmune bullous disease has seen a major shift of focus from more global immunosuppression to targeted immunotherapy. Anti CD 20 monoclonal antibody Rituximab revolutionized the therapeutics of autoimmune bullous disease particularly pemphigus. Though it is still being practiced off-label, evidences in the form of RCT and meta analysis are now available. Other novel anti CD 20 monoclonal antibodies like ofatumumab, veltuzumab, and ocrelizumab, tositumomab or obinutuzumab/GA101 may add to the therapeutic options in coming days. Beyond anti CD 20 monoclonal antibodies other options that show promise at least in select scenario are omalizumab, TNF inhibitors plasmapheresis and intravenous immunoglobulin. The present article will discuss the role of rituximab and other newer therapeutics in the treatment of autoimmune blistering disease, especially pemphigus and suggests their positions in the therapeutic ladder.

Abstract
Atopic dermatitis (AD) is a common chronic inflammatory skin disease that predominantly affects children. However, it can persist in adulthood and/or start at older ages. Due to its chronic nature and frequently occurring relapses, AD has a substantial effect on patients' quality of life, often requiring long-term systemic treatment, especially in adult patients, who are more frequently refractory to adequate topical treatment with mid- to high-potent corticosteroids and/or calcineurin inhibitors. Therefore, treatment with systemic therapies is often needed to take control of the disease, prevent exacerbations and improve quality of life. However, data regarding systemic treatment effectiveness and long-term safety in adult patients with AD are insufficient. Indeed, standardized international guidelines are lacking, and the treatment approach widely differs among diverse countries. This review focuses on the use of systemic treatments in adult AD patients analyzing published literature.

Abstract
Despite the expansion of the understanding in asthma pathophysiology and the continual advances in disease management, a small subgroup of patients remain partially controlled or refractory to standard treatments. Upon the identification of immunoglobulin E and other inflammatory mediators, investigations and developments of targeted agents have thrived. Omalizumab is a humanized monoclonal antibody that specifically targets the circulating immunoglobulin E, which in turn impedes and reduces subsequent releases of the proinflammatory mediators. In the past decade, omalizumab has been proven to be efficacious and well-tolerated in the treatment of moderate-to-severe asthma in both trials and real-life studies, most notably in reducing exacerbation rates and corticosteroid use. While growing evidence has demonstrated that omalizumab may be potentially beneficial in treating other allergic diseases, its indication remains confined to treating severe allergic asthma and chronic idiopathic urticaria. Future efforts may be focused on determining the optimal length of omalizumab treatment, seeking biomarkers that could better predict treatment response, as well as extending its indications.

Abstract
Omalizumab, a therapeutic humanized monoclonal antibody specific for human IgE, was introduced in clinical practice more than a decade ago as an add-on therapy for moderate-to-severe allergic asthma in patients aged ≥12 years. Omalizumab has been demonstrated to be effective in adults with uncontrolled persistent asthma, with an excellent safety profile. In simple terms, omalizumab works by inhibiting the allergic cascade, that is, by neutralization of the circulating free IgE. This leads to reduction in the quantity of cell-bound IgE, downregulation of high-affinity IgE receptors, and, eventually, prevention of mediator release from effector cells. Evidence is far less abundant on the role of omalizumab in pediatric asthma. Although efficacy and safety of omalizumab in children and adolescents with uncontrolled, persistent allergic asthma has been recognized as well, further studies are needed to clarify a number of open questions in this specific patient population.
