    Kurzfassung: Pegylated interferon and ribavirin for 72 weeks improve sustained virological response (SVR) in HCV genotype 1 (HCV-1) slow viral responders. Whether interleukin 28B (IL28B) single nucleotide polymorphism (SNP) genotypes and on-treatment viral responses can identify non-rapid virological response (RVR) patients who benefit from 48 or 72 weeks of therapy remains unclear. Methods Treatment-naive HCV-1 patients who failed to achieve RVR were randomly assigned to receive 48 ( n=168) or 72 ( n=167) weeks of therapy. Baseline factors and on-treatment virological responses at weeks 8 and 12 were evaluated for SVR in 289 compliant patients who received ≥80% of drug dosages and treatment duration, and had end of follow-up viral response. The stratified SVR rates for independent factors were compared by treatment duration. Results Treatment duration, IL28B rs8099917 genotypes, cirrhosis, week-8 viral response (undetectable HCV RNA at treatment week 8) and complete early virological response (cEVR) predicted SVR. In week-8 viral response patients, the SVR rates of 72-week and 48-week treatment were similar (75–88%), regardless of IL28B SNP genotypes or cirrhosis. In non-week-8 viral response patients who achieved cEVR, the SVR rate of 72-week treatment was higher than that of 48-week treatment for non-cirrhotic patients, regardless of IL28B SNP genotypes (91–100% versus 13–44%; P=0.001). Conclusions Although IL28B SNP genotypes predict SVR, they play a minor role when on-treatment viral responses are taken into consideration. On-treatment viral responses at weeks 8 and 12 are the key determinants to decide the optimal treatment duration in HCV-1 patients without RVR.

    Kurzfassung: Interleukin 28B (IL28B) single nucleotide polymorphism (SNP) genotypes and viral factors can predict sustained virological response (SVR) in HCV genotype-1 (HCV-1) patients receiving 48 weeks of pegylated interferon and ribavirin. Whether these factors would identify those patients who can benefit from a shorter duration of therapy remains unclear. Methods Treatment-naive HCV-1 patients ( n=662) receiving 24 or 48 weeks of combination therapy were enrolled. Baseline demographic data, HCV viral load, IL28B SNP genotypes (rs8099917), duration of therapy and rapid virological response (RVR) were evaluated to predict SVR. The SVR rates were further stratified by the independent factors and compared. Results The IL28B rs8099917 TT genotype, low baseline viral load (HCV RNA≤600,000 IU/ml), RVR and 48-week therapy independently predicted SVR. In RVR patients with the IL28B rs8099917 TT genotype, the SVR rate of 24-week therapy was comparable to 48-week therapy (95% versus 99%; P=0.21) at low baseline viral load, but was inferior to 48-week therapy (70% versus 97%; P 〈 0.001) at high baseline viral load. In non-RVR patients, the SVR rate of 24-week therapy was inferior to 48-week therapy for those with the IL28B rs8099917 TT genotype but high baseline viral load (23% versus 62%; P 〈 0.001), and those with the IL28B rs8099917 GT/GG genotype but low baseline viral load (0% versus 33%; P=0.02). Conclusions HCV-1 patients simultaneously bearing the IL28B rs8099917 TT genotype, low baseline viral load and RVR can benefit from a shorter duration of combination therapy.

    Kurzfassung: The aim of this study was to evaluate the effects of upper airway surgery on daytime sleepiness in nonobese patients with obstructive sleep apnea/hypopnea syndrome (OSA). Methods: This retrospective study included 121 consecutive adult nonobese patients with OSA from a tertiary academic medical center. Patients with OSA who refused continuous positive airway pressure therapy, or in whom it was unsuccessful, and then underwent OSA surgery were enrolled. Evaluations of excessive daytime sleepiness using the Epworth Sleepiness Scale (ESS) and major parameters of objective full-night polysomnography were collected preoperatively and at least 3 months postoperatively. Statistical analysis was performed using the Wilcoxon signed rank test and Wilcoxon rank sum test. Results: When pre- and postoperative ESS and polysomnographic parameters were compared in all patients, ESS scores, apnea/hypopnea index, and snoring index showed statistically significant improvements ( P = .007, P 〈 .001, and P 〈 .001, respectively). When patients were classified into mild, moderate, and severe OSA groups, snoring index had statistically significant improvements in all 3 groups, and apnea/hypopnea index had statistically significant decreases in the moderate and severe OSA groups. Although reductions in ESS scores were found in all 3 groups, the most statistically significant improvement was noted only in the severe OSA group. Conclusions: OSA surgery can improve daytime sleepiness in nonobese patients with OSA, especially for patients with severe OSA. This study elucidates the effects of OSA surgery on daytime sleepiness by excluding the major confounding factor of obesity. This study adds to the literature on the effects of upper airway surgery for nonobese patients with OSA on daytime quality of life.

    Kurzfassung: Although bevacizumab in combination with afatinib or erlotinib is an effective and safe first-line therapy for advanced epidermal growth factor receptor (EGFR)-mutated non-small-cell lung cancer (NSCLC), there are very few clinical data comparing afatinib and erlotinib combined with bevacizumab. We performed a retrospective multicenter analysis for the comparison of two combination therapies. Methods: Between May 2015 and October 2020, data of 135 stage IIIB/IV EGFR-mutated NSCLC patients receiving first-line afatinib or erlotinib combined with bevacizumab combination therapy in Linkou, Keelung, Chiayi, and Kaohsiung Chang Gung Memorial Hospitals were retrieved and retrospectively analyzed. Results: In all, 67 patients received afatinib plus bevacizumab, and 68 patients received erlotinib plus bevacizumab. Afatinib combined with bevacizumab had an objective response rate (ORR) of 82.1% and a disease control rate (DCR) of 97.0%, and the ORR and DCR were 83.8 and 95.6%, respectively, in the erlotinib combined with bevacizumab group ( p = 0.798 and p = 1.000). The median progression-free survival was 20.7 and 20.3 months for the afatinib plus bevacizumab group and the erlotinib plus bevacizumab group, respectively [hazard ratio (HR) = 1.02; 95% confidence interval (CI), 0.891–1.953; p = 0.167). The overall survival was 41.9 and 51.0 months for the afatinib plus bevacizumab group and erlotinib plus bevacizumab group, respectively (HR = 1.42; 95% CI, 0.829–2.436; p = 0.201). The secondary EGFR-T790M mutation rates after disease progression were 44% in the afatinib plus bevacizumab group and 58.8% in the erlotinib plus bevacizumab group ( p = 0.165). Skin toxicity was the most frequent treatment-related adverse event (AE) in both treatment groups. Diarrhea, an AE, occurred significantly more frequently in the afatinib plus bevacizumab group than in the erlotinib plus bevacizumab group ( p  〈  0.05). Conclusion: Afatinib combined with bevacizumab was equally as effective as erlotinib combined with bevacizumab for untreated advanced EGFR-mutated NSCLC. Prospective clinical studies that explore bevacizumab combined with afatinib or erlotinib for advanced EGFR-mutated NSCLC are warranted.

    Kurzfassung: Osteoporosis is easily overlooked in male patients, especially in the field of rheumatic diseases mostly prevalent with female patients, and its link to pathogenesis is still lacking. Attenuated monocyte apoptosis from a transcriptome-wide expression study illustrates the role of monocytes in osteoporosis. This study tested the hypothesis that the monocyte percentage among leukocytes could be a biomarker of osteoporosis in rheumatic diseases. Eighty-seven males with rheumatic diseases were evaluated in rheumatology outpatient clinics for bone mineral density (BMD) and surrogate markers, such as routine peripheral blood parameters and autoantibodies. From the total number of 87 patients included in this study, only 15 met the criteria for diagnosis of osteoporosis. Both age and monocyte percentage remained independently associated with the presence of osteoporosis. Steroid dose (equivalent prednisolone dose) was negatively associated with BMD of the hip area and platelet counts were negatively associated with BMD and T score of the spine area. Besides age, monocyte percentage meets the major requirements for osteoporosis in male rheumatic diseases. A higher monocyte percentage in male rheumatic disease patients, aged over 50 years in this study, and BMD study should be considered in order to reduce the risk of osteoporosis-related fractures.

    Kurzfassung: Evidence suggests increased mortality rates among autistic individuals. However, risks of mortality, including natural-cause, suicide, and accident mortalities, among autistic individuals remain unclear. Among the entire Taiwanese population ( N = 29,253,529), between 2003 and 2017, 45,398 autistic individuals were identified and 1:4 matched to 181,592 non-autistic individuals based on birth year and sex. All-cause mortality, including natural-cause, accident, and suicide mortalities, was assessed from 2003 to 2017 between the two cohorts. Cox regression models were used to investigate the mortality risk between autistic and non-autistic individuals. Autistic individuals had increased likelihoods (hazard ratio, 95% confidence interval) of all-cause mortality (3.43, 3.00–3.92), natural-cause mortality (4.73, 3.99–5.60), and suicide mortality (3.67, 2.37–5.68) compared with non-autistic individuals. In particular, autistic males were more likely to die by suicide (hazard ratio: 3.81, 95% confidence interval: 2.37–6.13), and autistic females were more likely to die of accident (hazard ratio: 5.07, 95% confidence interval: 2.54–10.13) compared with non-autistic individuals. Appropriate and effective medical and mental health care is recommended for autistic individuals. Lay abstract Our study was the first population-based study in an Asian country to investigate the mortality rates among autistic individuals. Among the entire Taiwanese population ( N = 29,253,529), between 2003 and 2017, 45,398 autistic individuals were identified and 1:4 age-/sex-matched to 181,592 non-autistic individuals. We found that autistic individuals had increased risks of all-cause mortality, natural-cause mortality, and suicide mortality compared with non-autistic individuals. Furthermore, autistic males were more likely to die by suicide, and autistic females were more likely to die of accident compared with the non-autistic individuals.

    Kurzfassung: Acute exacerbations (AEs) of chronic obstructive pulmonary disease (COPD) can affect health status, hospitalization and readmission rates, and disease progression. This study aimed to identify independent markers associated with COPD AEs. Methods This study included male patients with COPD and collected data regarding their AEs and baseline clinical parameters. Results We included 149 male patients. Among them, 58 were included in the year 0 high-AE group and 91 in the low-AE group. Multivariate analysis revealed that the high-AE group had higher white blood cell count, lower serum albumin level, and post-bronchodilator (BD) forced expiratory volume in one second (FEV 1 ) (%) with a combined receiver operating characteristic curve (ROC) of 0.721 ( p 〈 0.001). Additionally, 34 patients were included in the year 1 high-AE group and 70 in the low-AE group ( p 〈 0.001). Multivariate analysis revealed that the high-AE group had higher platelet count, positive asthma history, and lower pre-BD FEV 1 (%) with a combined ROC of 0.782 ( p 〈 0.001). Conclusion In male patients with COPD, baseline white blood cell count, albumin level, and post-BD FEV 1 (%) were correlated with year 0 AE; on the other hand, baseline platelet count, positive asthma history, and pre-BD FEV 1 (%) were associated with year 1 AE.

    Kurzfassung: To elucidate the interaction between hypoxia-induced autophagy and glycolysis in nasal polyp fibroblasts, and the regulatory role of Sirtuin 6 (SIRT6) in the pathogenesis of nasal polyp. Objective Through examining the expressions of lactate dehydrogenase (LDH), microtubule-associated protein II light chain 3 (LC3II) (an autophagy marker), and production of lactate under hypoxia, the interaction between autophagy and glycolysis was investigated. The role of SIRT6 on the hypoxia-induced autophagy and glycolysis was also examined. Methods Nasal polyp specimens were used to examine the expressions of hypoxia-inducible factor (HIF) 1α, LDH, and LC3II by Western blot analysis, and primary cultures of nasal polyp fibroblasts were established from resected nasal polyps to measure hypoxia-induced LDH and LC3II expression by Western blot analysis and lactate production by colorimetry. Forced expression of SIRT6 with a lentiviral-based technique was used to evaluate its suppressive effect on autophagy and glycolysis. Immunohistochemical staining was performed to detect the expressions of SIRT6, LDH, and beclin (another autophagy marker) in nasal polyps. Results Expression of HIF-1α, LDH, and an autophagy marker, LC3II, are increased in nasal polyp specimens, and forced expression of SIRT6 in nasal polyp fibroblasts inhibited LDH expression, lactate production under hypoxia, and SIRT6. An immunohistochemistry study of nasal polyp showed that SIRT6 expression was reduced and LDH and beclin were enhanced. Conclusion Analysis of these data indicated that hypoxia may contribute to the formation of nasal polyp by promoting autophagy in nasal polyp fibroblasts. Through the antiglycolytic activity of SIRT6, the autophagy was suppressed, which was beneficial to nasal polyp formation. Modulation of glucose metabolism through SIRT6-based strategy may possess therapeutic potential for nasal polyposis in the future.

    Kurzfassung: Tanshinone IIA (Tan IIA) and sinapic acid (SA) are 2 components separately isolated from 2 Asian medicinal plants, Hydnophytum formicarum Jack and Salvia miltiorrhiza Bunge. The antitumor activities of them were worth exploring, therefore, we examined their antitumor activities in A549, HCT116, HeLa, and Colo320 cancer cell lines by means of WST-1 assay. The results show that Tan IIA exerted far higher (IC 50 from 1.0 ± 0.0 to 166.3 ± 24.0 µg/mL) antiproliferative activities than SA (IC 50 from 2236.3 ± 484.1 to 〉 10 000.0 µg/mL). Of the 4 cell lines, A549 cells were the most sensitive to Tan IIA; thus, we used Western blotting to explore the cytotoxic mechanisms of Tan IIA in A549 cells and found that they rely on simultaneous induction of apoptosis and necroptosis in the cells. Apoptosis was hallmarked by the induction of cleaved caspase-3 by Tan IIA and necroptosis by the necroptotic marker proteins cyclophilin A and high mobility group box 1 (HMGB1), as well as increased lactate dehydrogenase (LDH) activities. The necroptotic effect was confirmed by the necroptosis inhibitor necrostatin-1 (Nec-1), which eliminated these effects and restored cell survival rates. The levels of cyclophilin A decreased in response to the pan-caspase inhibitor z-VAD-fmk, and those of cleaved caspase-3 decreased in response to Nec-1. Conclusively, Tan IIA has the potential to prevent lung cancer and the mechanism seems to be apoptosis and necroptosis, of which the relationship is mutually interdependent. This is the first report of Tan IIA eliciting necroptosis in A549 cells. Tan IIA may be used for necroptosis-based cancer therapy, especially to overcome apoptosis resistance.

    Kurzfassung: Atopic dermatitis (AD) is a chronic inflammatory disease of the skin that substantially affects a patient’s quality of life. While steroids are the most common therapy used to temporally alleviate the symptoms of AD, effective and nontoxic alternatives are urgently needed. In this study, we utilized a natural, plant-derived phenolic compound, phloretin, to treat allergic contact dermatitis (ACD) on the dorsal skin of mice. In addition, the effectiveness of phloretin was evaluated using a mouse model of ACD triggered by 2,4-dinitrochlorobenzene (DNCB). In our experimental setting, phloretin was orally administered to BALB/c mice for 21 consecutive days, and then, the lesions were examined histologically. Our data revealed that phloretin reduced the process of epidermal thickening and decreased the infiltration of mast cells into the lesion regions, subsequently reducing the levels of histamine and the pro-inflammatory cytokines interleukin (IL)-6, IL-4, thymic stromal lymphopoietin (TSLP), interferon-γ (IFN-γ) and IL-17A in the serum. These changes were associated with lower serum levels after phloretin treatment. In addition, we observed that the mitogen-activated protein kinase (MAPK) and NF-κB pathways in the dermal tissues of the phloretin-treated rodents were suppressed compared to those in the AD-like skin regions. Furthermore, phloretin appeared to limit the overproliferation of splenocytes in response to DNCB stimulation, reducing the number of IFN-γ-, IL-4-, and IL-17A-producing CD4 + T cells in the spleen back to their normal ranges. Taken together, we discovered a new therapeutic role of phloretin using a mouse model of DNCB-induced ACD, as shown by the alleviated AD-like symptoms and the reversed immunopathological effects. Therefore, we believe that phloretin has the potential to be utilized as an alternative therapeutic agent for treating AD.
