A 46-year-old man with plaque psoriasis suffered from EP following the sudden discontinuation of medications. He was diagnosed with COVID-19 one month before erythroderma appeared. The body surface area involvement was 96% and psoriasis area severity index was 49.8. His general condition and laboratory examination were within normal limits. He was treated with cyclosporine-A for one month after being healed from COVID-19 with significant improvement. Excessive production of proinflammatory cytokines in COVID-19 plays a role in the pathogenesis of psoriasis. This condition should be managed appropriately to minimize the complication. Cyclosporine-A is the first-line therapy for EP because of its effectiveness and good safety profile. It is also shown a beneficial effect in COVID-19 infection in vitro.","PeriodicalId":8488,"journal":{"name":"Asia Pacific Allergy","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45756426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An estimated 20% of those with AD comprise a subset of patients with treatment-resistant AD, for whom traditional therapeutics and management strategies are unsuccessful. Physical symptoms significantly impact quality of life for patients and caregivers. The condition is chronic and may persist throughout the lifespan with recurrent episodes. Novel AD therapeutics offer new opportunities to resolve symptoms of treatment-resistant more effectively AD. Recently developed pharmacological agents were developed with an appreciation of AD as a heterogeneous condition. New advances include topical, oral, and injectable therapeutics with novel mechanisms of action. In addition, advances in clinical practice, including the application of digital tools, can promote a personalized medicine approach. For example, teledermatology for chronic conditions such as AD have been embraced by clinicians and patients; communicating symptoms via photographs can augment patient symptom trackers and aid trigger identification. Digital tools can also be used to increase medication adherence and improve patient/caregiver engagement. Integrating the above is a personalized medicine approach. Advanced therapeutics with novel mechanisms of action, integrated with digital tools, and trends toward patient-centered medicine can assist this chronic, heterogeneous condition via precision medicine and better treat treatment-resistant AD.","PeriodicalId":8488,"journal":{"name":"Asia Pacific Allergy","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46125987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The exact pathophysiology of this disease has not received much attention. Moreover, while it has been reviewed many times [1, 2], there is little mention of senile erythroderma. The accumulated findings [1, 2] reveal 3 factors involved in its etiology: drugs such as carbamazepine, preexisting skin diseases such as psoriasis [1], and stages of malignancies such as cutaneous T-cell lymphomas. Li and Zheng [2] reported the most prevalent causative factors—preexisting dermatoses (70.77%), followed by idiopathic causes (14.23%), drug-induced reactions (12.69%), and malignancies (2.31%). Among the pre-existing dermatoses, psoriasis was the most common etiology (55%). Several case analyses show that males are 4 times more likely to be affected by erythroderma than females [1, 2]. The average age is 52 to 57 years, including those in 80s [1, 2]. One study reported a unique case of erythroderma caused by propolis [3]—a food product produced by honeybees. Steroid withdrawal erythroderma [4] has been reported; as it is caused by medical care, it is called iatrogenic. Patients with systemic eczema have received steroids for external use at various medical institutions for many years due to the intractability of their conditions. In cases of steroid withdrawal, erythroderma occasionally occurs. As the cases caused by an underlying disease are diverse, dermatologists and clinicians should first determine the possible cause in patients with erythroderma.","PeriodicalId":8488,"journal":{"name":"Asia Pacific Allergy","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47809836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biologics or bronchial thermoplasty (Bio/BT) are recommended for such patients. Objectives To determine which definitions of severe uncontrolled asthma are associated with an additional Bio/BT treatment in patients with severe uncontrolled asthma. Methods Consecutive 107 asthmatics (including 15 patients for whom Bio/BT was introduced within 3 months after examination), classified as treatment step 4 according to the Global Initiative for Asthma 2015 guideline, were eligible for this analysis. Patients were assessed using the European Thoracic Society/American Thoracic Society (ERS/ATS) severe uncontrolled asthma guideline as defined by these 4 characteristics: poor control (ACT < 20), frequent exacerbations (≥2/yr), admissions (≥1/yr), and airflow limitation (forced expiratory volume in 1 second < 80% of predicted), along with comorbidities, and biomarkers, including blood granulocytes, fractional nitric oxide, and capsaicin cough reflex sensitivity (C-CS). These indices were compared between patients with and without Bio/BT introduction, and multivariate logistic regression analysis was performed to determine the association of the 4 definitions with treatment needs for Bio/BT. Results Patients who were introduced to Bio/BT had heightened C-CS, heavier smoking history, and a greater prevalence of diabetes mellitus than those without (p < 0.05). Poor asthma control (ACT < 20), frequent exacerbations (≥2/yr), and admissions (≥1/yr) were relevant to the future use of Bio/BT in the multivariate regression analysis. Type 2-related biomarkers including absolute eosinophil counts were higher in patients in the Bio introduction group than in the BT introduction group. Meanwhile, there was no significant difference of the 4 characteristics of severe uncontrolled asthma definition between patients in the Bio and those in the BT groups. Conclusion Although multiple factors such as treatment cost and asthma phenotypes affect treatment decision-making, the definition of poor asthma control, frequent exacerbations and admission by the ERS/ATS guidelines were important factors for an additional intensive treatment for severe uncontrolled asthma.
