Abstract Background Transglutaminase 2 (TG2), a multifunctional calcium‐dependent acyltransferase, is upregulated in asthmatic airways and reported to play a role in the pathogenesis of allergic asthma. However, the underlying mechanism is not fully understood. Objective To investigate the role of TG2 in alternative activation of alveolar macrophages by using murine asthma model. Methods TG2 expression was assessed in induced sputum of 21 asthma patients and 19 healthy controls, and lung tissue of ovalbumin (OVA)‐induced murine asthma model. To evaluate the role of TG2 in asthma, we developed an OVA asthma model in both TG2 null and wild‐type mice. The expression of M2 macrophage markers was measured by fluorescence‐activated cell sorting (FACS) after OVA sensitization and challenge. To evaluate the effect of TG2 inhibition in vitro, interleukin 4 (IL‐4) or IL‐13‐stimulated expression of M2 macrophage markers was measured in CRL‐2456 cells in the presence and absence of a TG2 inhibitor. Results The expression of both TG2 and M2 markers was increased in the sputum of asthmatics compared with that of healthy controls. The expression of TG2 was increased in macrophages of OVA mice. Airway hyperresponsiveness, and the number of inflammatory cells, including eosinophils, was significantly reduced in TG2 null mice compared with wild‐type mice. Enhanced expression of M2 markers in OVA mice was normalized by TG2 knockout. IL‐4 or IL‐13‐stimulated expression of M2 markers in alveolar macrophages was also attenuated by TG2 inhibitor treatment in vitro. Conclusion Our results suggest that TG2‐mediated modulation of alveolar macrophage polarization plays important roles in the pathogenesis of asthma.

Abstract Objective Lamotrigine is one of the most widely used antiepileptic drugs, but it has a critical issue of a skin rash if the starting dose is too high or the escalation rate is too rapid. We investigated the efficacy and safety of a novel and rapid titration protocol for lamotrigine that takes only 11 days to reach a daily dose of 200 mg. Methods We prospectively enrolled 33 adult patients (age 18‐85) who were diagnosed with epilepsy and started lamotrigine administration for the first time at a single tertiary hospital. Our new protocol starts with a subthreshold dose of the drug and then administers a stepwise‐incremental dose until reaching the full therapeutic dose within 11 days. Results Of 29 patients analyzed, only two (6.9%) experienced idiosyncratic skin rash before the first follow‐up visit at 2 weeks (±3 days). In addition, a therapeutic concentration was reached in more than 75% of studied patients after 2 weeks of lamotrigine administration. Significance These findings demonstrate the value of the novel tolerance induction protocol for lamotrigine, which could widen the available application of lamotrigine in various situations. However, this study is a preliminary study limited by a small number of patients and its nonrandomized and open‐label design, so the current protocol needs more rigorous clinical evaluations before the application to the real clinical setting.

Abstract Background Several type B adverse drug reactions (ADRs), especially severe cutaneous adverse reactions (SCARs), are associated with particular human leukocyte antigen (HLA) genotypes. However, pre‐stored HLA information obtained from other clinical workups has not been used to prevent ADRs. We aimed to simulate the preemptive use of pre‐stored HLA information in electronic medical records to evaluate whether this information can prevent ADRs. Methods We analyzed the incidence and the risk of ADRs for selected HLA alleles (HLA‐B*57:01, HLA‐B*58:01, HLA‐A*31:01, HLA‐B*15:02, HLA‐B*15:11, HLA‐B*13:01, HLA‐B*59:01, and HLA‐A*32:01) and seven drugs (abacavir, allopurinol, carbamazepine, oxcarbazepine, dapsone, methazolamide, and vancomycin) using pre‐stored HLA information of transplant patients based on the Pharmacogenomics Knowledge Base guidelines and experts' consensus. Results Among 11,988 HLA‐tested transplant patients, 4092 (34.1%) had high‐risk HLA alleles, 4583 (38.2%) were prescribed risk drugs, and 580 (4.8%) experienced type B ADRs. Patients with HLA‐B*58:01 had a significantly higher incidence of type B ADR and SCARs associated with allopurinol use than that of patients without HLA‐B*58:01 (17.2% vs. 11.9%, odds ratio [OR] 1.53 [95% confidence interval {CI} 1.09–2.13], p = 0.001, 2.3% versus 0.3%, OR 7.13 [95% CI 2.19–22.69], p

HLA-B*58:01 is a well-known risk factor for allopurinol-induced severe cutaneous adverse reactions (SCARs). However, only a minority of HLA-B*58:01 carriers suffer SCARs after taking allopurinol. The aim of this study was to investigate subsidiary genetic markers that could identify those at further increased risk of developing allopurinol-induced drug reaction with eosinophilia and systemic symptoms (DRESS) in subjects with HLA-B*58:01.Subjects with B*58:01 were enrolled (21 allopurinol-induced DRESS and 52 allopurinol-tolerant control). HLA-A, -B, -C and -DRB1 alleles were compared. Comparison of risk between HLAs and allopurinol-induced SCAR in separate populations was performed to support the results. Kruskal-Wallis test, Pearson's chi-square test, Fisher's exact test and binary logistic regression were used to analyze the risk of SCAR development.Frequencies of A*24:02 (71.4 vs. 17.3%,The additional secondary screening with A*24:02 and DRB1*13:02 alleles may identify those at further increased risk of allopurinol-induced DRESS in B*58:01 carriers.

Background Chlorine is widely used in daily life as disinfectant. However, chronic exposure to chlorine products aggravates allergic TH 2 inflammation and airway hyperresponsiveness (AHR). Innate lymphoid cells (ILCs) in airways contribute to the inception of asthma in association with virus infection, pollution, and excess of nutrient, but it is not known whether chronic chlorine exposure can activate innate immune cells. The aim of this study was to evaluate the impact of chlorine inhalation on the innate immunity such as ILCs and macrophages in relation with the development of asthma by using murine ovalbumin (OVA) sensitization/challenge model. Methods Six-week-old female BALB/c mice were sensitized and challenged with OVA in the presence and absence of chronic low-dose chlorine exposure by inhalation of naturally vaporized gas of 5% sodium hypochlorite solution. AHR, airway inflammatory cells, from BALF and the population of ILCs and macrophages in the lung were evaluated. Results The mice exposed to chlorine with OVA (Cl + OVA group) showed enhanced AHR and eosinophilic inflammation compared to OVA-treated mice (OVA group). The population of TH 2 cells, ILC2s, and ILC3s increased in Cl + OVA group compared with OVA group. CD11cint macrophages also remarkably increased in Cl + OVA group compared with OVA group. The deletion of macrophages by clodronate resulted in reduction of ILC2s and ILC3s population which was restored by adoptive transfer of CD11cint macrophages. Conclusions Chronic chlorine inhalation contributes to the exacerbation of airway inflammation in asthmatic airway by mobilizing pro-inflammatory macrophage into the lung as well as stimulating group 2 and 3 ILCs.

Our paper focuses on Asian female managers and the influence of individual and organizational factors on objective and subjective career success. We use a survey and interviews of female managers in South Korea post-1997 Asian financial crisis and pre-2008 global financial crisis. Importantly, we find male-dominated business and societal cultures stemming from the context to be crucial. The implications of our findings include the greater need to take into account the restraints on individual actions and the need for state and management support. We conclude that the role of context is too often underplayed and needs to be more fully addressed in analysis of female careers in not only Asia, but also more widely.

Summary. Introduction: After intensive tobacco control efforts in recent decades, the prevalence of active smoking has decreased. However, the hazardous effect of indirect exposure to cigarette smoke is often underestimated, especially in children. We aimed to investigate the effect of parental smoking on the respiratory morbidity of the children of parents who smoke by evaluating the relationship between parental smoking behavior and children’s respiratory symptoms. Methods: We conducted a cross-sectional follow-up study of 31,584 children aged 6–11 in an urban community in Anyang City, Korea. The children’s parents were asked about their smoking status and completed questionnaires regarding their children’s symptoms related to asthma and other upper or lower respiratory illnesses. Our analysis focused on a comparison of the frequency of respiratory and ocular symptoms according to parental smoking status, whether it was non-smoking (Non-S), indirect passive smoking (third-hand smoking, THS) or direct passive smoking (second-hand smoking, SHS). Results: The children with Non-S patients were 40.9%, THS group 40.6%, and SHS group 18.5%. THS group showed lower ORs for most respiratory symptoms when compared with those of SHS group, however, THS group revealed increased ORs compared with Non-S in cough-related symptoms. There was a linear trend in frequencies of cough and sputum-related symptoms according to the degree of exposure to cigarette smoke (P < 0.05). Conclusion: The prevalence of respiratory symptoms increased in children exposed to parental smoking including SHS and THS. To avoid the risk of respiratory and allergic disease by environmental tobacco smoke, absolute smoking cessation by parents is strongly recommended. Pediatr Pulmonol. 2012; 47:338–345.
