74) but LIA had a fair agreement with ELISA and CLIF assay (? = 0.37, and 0.35 respectively). For the detection of anti-nucleosome, anti-nRNP/Sm, anti-Sm, anti-SSA, and anti-SSB antibodies, LIA had a substantial to perfect agreement with ELISA (? = 0.64, 0.78, 0.68, 0.91, and 0.74, respectively). Anti-dsDNA-NcX ELISA and anti-dsDNA CLIF assay had equally diagnostic performance (sensitivity, 66% vs. 68%, and specificity, 96% vs. 94%, respectively) whereas, anti-dsDNA LIA has low sensitivity (22%) but high specificity (100%). CONCLUSIONS LIA, ELISA, and CLIF demonstrated comparable performance for the detection of specific antinuclear-antibodies. However, there were some discrepancy between assays particularly in the detection of anti-dsDNA antibody.BACKGROUND Patients with chronic spontaneous urticaria (CSU) have been reported to experience increased disease activity in response to the oral intake of hot pepper (Capsicum spp.). As of now, it is unclear how common this is.  https://www.selleckchem.com/EGFR(HER).html  OBJECTIVE We assessed patients with CSU for the prevalence of disease worsening after the intake of hot pepper and characterized its effects on their urticaria. METHODS A questionnaire-based survey study in adult patients with CSU and a history of hot pepper consumption was carried out at a reference center for urticaria in Turkey. CSU patients who had co-existing chronic inducible urticaria were excluded from the study. RESULTS Of the eighty-five patients with CSU included in this study, 46% (39 of 85) reported worsening of their urticaria after consuming hot pepper. Demographic features, duration of CSU and control status of urticaria were not different between patients who experienced worsening of their urticaria after the intake of hot pepper and those who did not. In affected patients, worsening of their symptoms started 1.2 ± 1.2 hours after the intake of hot pepper and lasted for 3.3 ± 6.8 hours. Symptoms disappeared significantly faster in patients who took antihistamines after worsening of their urticaria with hot pepper (0.7 ± 0.6 vs. 5.8 ± 8.8 hours; p = 0.003). CONCLUSIONS Worsening of urticaria is common and relevant in patients with CSU in Turkey. Further studies are needed to explore if this is also the case in other geographical regions and to identify and characterize the underlying mechanisms.BACKGROUND Endotoxin exposure may cause asthma exacerbations and contribute to non-atopic respiratory diseases. Viet Nam, a country with multiple house types, is lacking data on indoor contamination by endotoxin in regard with house types. OBJECTIVE The comparison of measured settled dust endotoxin levels among house types in Ho Chi Minh city will allow to classify the house types regarding health risks. METHODS This study is a cross-sectional study. Five identified house types were selected apartment (APA), rental (REN), rural (RUR), slum (SLU) and tube house (TUB). One hundred house's endotoxin contamination was evaluated by questionnaire and dust sampling. Endotoxin concentration was measured by kinetic chromogenic Limulus assay. RESULTS dotoxin concentration (geometric mean 126.0 EU/mg, 95%CI 118.3-133.7) is particularly high in settled house dust compared to western countries and is significantly associated with the house type. The highest level was found in RUR in each room (p = 0.002 for living room; p less then 0.0001 for bedrooms and for kitchens). Concerning levels in the different rooms, APA and TUB form a low group while REN and SLU (p less then 0.001) form a median group and RUR the highest (p less then 0.001). Differences in endotoxin levels were associated to the presence of dog, chicken and farm animals, wood cooking, air-conditioning usage. CONCLUSIONS Further understanding of the relevant factors to endotoxin levels would contribute to prevent asthma exacerbations and chronic respiratory diseases. Public health interventions to reduce exposure to endotoxin include improving housing conditions, eliminating risk factors and a priority to high-risk house types.BACKGROUND Despite recent advances in the treatment of drug reaction with eosinophilia and systemic symptoms (DRESS), the mainstay of treatment involves discontinuing the culprit drugs and administering topical or systemic corticosteroid. OBJECTIVE The clinical use of a tumor necrosis factor (TNF)-alpha inhibitor was rarely explored in treatment of DRESS. METHODS We present a case of corticosteroid-induced DRESS that was successfully treated with a TNF-alpha inhibitor without sequalae. RESULTS This is the first case report that showed the clinical use of a TNF alpha inhibitor in treating corticosteroids- induced DRESS and immediate hypersensitivity reactions. The HLA-B*5801 was identified as a possible genetic factor associated with a corticosteroid-induced DRESS. CONCLUSIONS A TNF-alpha inhibitor could be a primary option in treating DRESS, especially in patients with hypersensitivity reaction to corticosteroids.The provision of healthy and safe food is vital for human health, and the addition of unnecessary sugars in foodstuffs is an important global issue, leading to multiple long- and short-term health issues and spiraling costs for individuals and governments alike. The negative effect of excess sugar consumption contributes to adverse health conditions, including obesity, type 2 diabetes, and poor oral health in both high and low resource settings. A key plank of governmental and health promotion bodies' nutritional guidance is to raise public awareness of "hidden" sugars, salt, and fats, such as found in processed foods and sugar-sweetened beverages (SSBs), and guide individuals to reduce their consumption. This rapid narrative review brings together some of the key issues identified in the literature around the consumption of SSBs, including patterns of consumption, the general impact on human health and nutrition, specific effects on oral health and the oral microbiome, and strategies to address over-consumption. The range of long-term adverse effects on health is often misunderstood or unknown by the public. However, some strategies have succeeded in reducing the consumption of SSBs, including public health strategies and interventions and the imposition of taxes or levies, and this article makes recommendations for action. © 2020 Journal of Population Therapeutics and Clinical Pharmacology.
