Abstract
BACKGROUND Data on the use of biologic therapy and malignancy risk are inconsistent due to limited long-term robust studies. OBJECTIVES To assess the malignancy risk in patients with secukinumab-treated psoriasis, psoriatic arthritis (PsA) and ankylosing spondylitis (AS). METHODS This integrated safety analysis from both the secukinumab clinical trial programme and postmarketing safety surveillance data included any patient receiving at least one approved dose of secukinumab with a maximum of 5 years of follow-up. Safety analyses evaluated the rate of malignancy using exposure-adjusted incidence rates [EAIR; incidence rates per 100 patient treatment-years (PTY)]. Standardized incidence ratios (SIRs) were reported using the Surveillance, Epidemiology, and End Results Program (SEER) database as a reference population. Crude incidence of malignancy was also reported using postmarketing surveillance data. RESULTS Safety data from 49 clinical trials with secukinumab-treated patients were included: 10 685 patients with psoriasis, 2523 with PsA and 1311 with AS. Across indications over a 5-year period, the EAIR of malignancy was 0·85 per 100 PTY [95% confidence interval (CI) 0·74-0·98] in secukinumab-treated patients, corresponding to 204 patients per 23 908 PTY. Overall, the observed vs. expected number of malignancies from secukinumab clinical trial data were comparable, as indicated by an SIR of 0·99 (95% CI 0·82-1·19) across indications. The estimated crude cumulative incidence reporting rate per 100 PTY for malignancy was 0·27 in the postmarketing surveillance data across indications with a cumulative exposure of 285 811 PTY. CONCLUSIONS In this large safety analysis, the risk of malignancy was low for up to 5 years of secukinumab treatment. These data support the long-term use of secukinumab in these indications.

Abstract
Background Since the outbreak of coronavirus disease 2019 (COVID-19), the pattern of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA shedding has not been well characterized. Methods In our study, 652 patients in Wuhan Designated Hospital were recruited, and their clinical and laboratory findings were extracted and analyzed. Results The median duration of SARS-CoV-2 RNA detection was 23 days [interquartile range (IQR), 18 days] from symptom onset. Compared to patients with early viral RNA clearance (<23 days after illness onset), we found that patients with late viral RNA clearance (≥23 days) had a higher proportion of clinical features, as follows: symptoms, including fever, dry cough, and sputum production; comorbidities, including hypertension, chronic kidney disease, uremia, chronic liver disease, anemia, hyperlipidemia, and bilateral lung involvement; complications, such as liver injury; delayed admission to hospital; laboratory parameters at baseline, including higher eosinophils, uric acid, cholesterol, triglycerides, and lower hemoglobin; and less treatment with arbidol, chloroquine, or any antivirals. After generalized linear regression, prolonged SARS-CoV-2 RNA shedding was independently associated with younger age; delayed admission to hospital; symptoms including fever, shivering, and sputum production; comorbidities including hypertension, diabetes, cardiovascular disease, anemia, hyperlipidemia, uremia, and lung involvement; and higher alanine aminotransferase (ALT), uric acid, and cholesterol levels at baseline. Conclusions In conclusion, the factors mentioned above are associated with the negative conversion of SARS-CoV-2 RNA. A deeper insight into virological dynamics will be helpful for establishing patient discharge and quarantine release criteria.

Abstract
BACKGROUND Many patients with mild asthma are undiagnosed and untreated due to the low diagnostic sensitivity of bronchodilation test (BDT). OBJECTIVE To investigate whether airway reversibility in BDT and fractional exhaled nitric oxide (Feno) can predict the response to antiasthma therapy (RAT) in patients with suspected asthma. METHODS This open-label, prospective cohort study included patients with chronic recurrent asthma symptoms, normal FEV1, and negative BDT results. Inhaled corticosteroids and long-acting β agonists were given for 4 weeks. A positive RAT was defined as improved symptoms and an increase of more than 200 mL in FEV1 after inhaled corticosteroid/long-acting β agonist treatment. Lung tissues from another 19 patients who underwent pneumectomy for lung nodules were also analyzed. RESULTS Of 110 patients recruited, 102 completed the study. Patients in the positive RAT group had a higher Feno and greater absolute (Δ) and percent (Δ%) improvements in forced vital capacity, FEV1, and forced expiratory flows (FEFs) in BDT than in the negative RAT group. The area under the curves of Feno, ΔFEV1%, ΔFEF25-75% (percent improvement in FEF at 25%-75% of forced vital capacity), and ΔFEF75% (percent improvement in FEF at 75% of forced vital capacity) for positive RAT were 0.703, 0.824, 0.736, and 0.710, with cutoff values of 33 parts per billion and 3.50%, 15.26%, and 26.04%, respectively. A joint model of Feno and ΔFEV1% increased the area under the curve to 0.880. Inflammatory cytokines were higher in the lung tissues of patients with predicted positive RAT than in those with predicted negative RAT. CONCLUSIONS ΔFEV1% in BDT together with Feno predicted a positive RAT and an asthma diagnosis in patients with a normal FEV1 and negative BDT. Evidence of pathological changes increases the credibility of the predictive model.

Abstract
Background Poor control of asthma results from many factors, partly due to inadequate knowledge towards asthma among patients. It is necessary to know patients’ knowledge level before education. However, there is no accepted instrument to evaluate knowledge of asthma in Chinese patients with asthma. The study aims to develop a Chinese version of Patient-completed Asthma Knowledge Questionnaire (PAKQ) to assess its reliability, validity, and responsiveness for testing its clinical application in Chinese adult patients with asthma. Methods After translation, back-translation, and cross-cultural adaptation of the PAKQ into Chinese version, a survey of patients with asthma (n=464) in China was conducted. Demographics and clinical data were collected in addition to questionnaires concerning cognition of asthma, education, history, and asthma control test score. The PAKQ was then completed. 14±4 days after the initial assessment, the participants completed the retested questionnaire and again completed the questionnaire immediately after education. The reliability and the construct validity were evaluated. The optimal cut-off points for predicting disease knowledge among asthma patients were determined using the Youden index method. Results The Chinese version of PAKQ showed high internal consistency (Cronbach’s alpha =0.888) at baseline and an acceptable 2-week test-retest reliability (ICC =0.932, r=0.874). On the basis of large modification indices (>10), this four-factor questionnaire was found to fit the data satisfactorily (χ2/df =1.695, RMSEA =0.039, GFI =0.856, CFI =0.885, and SRMR =0.058). Paired t-tests showed significant changes on pre-educational and post-educational tests (t=22.83, df=463, P<0.0001). The optimal cut-off value of the PAKQ total score for assessing patients’ knowledge level was 35 points (AUC =0.757). Conclusions The Chinese version of the PAKQ questionnaire was developed and validated in terms of reliability and validity as an effective instrument for the insight into asthma knowledge of adult patients with asthma in China. Future research will evaluate the utility of the instrument in clinical practice.

Abstract
Background:Pooled safety data has been reported with secukinumab (SEC) in patients (pts) with Psoriatic arthritis (PsA), Ankylosing Spondylitis (AS) and Psoriasis (PsO).1Objectives:To report longer-term safety data of SEC treatment in PsA, AS, PsO pts up to 5 years.Methods:The integrated clinical trial safety dataset included data pooled from 28 randomised controlled clinical trials of SEC 300 or 150 or 75 mg in PsO (11 Phase 3 and 8 Phase 4 trials), PsA (5 Phase 3 trials), and AS (4 Phase 3 trials), along with post-marketing safety surveillance data with a cut-off date of 25 December 2018. Adverse events (AEs) were reported as exposure-adjusted incident rates (EAIRs) per 100 pt-years. Analyses included all pts who received ≥1 dose of SEC.Results:A total of 12637 pts (8819, 2678 and 1140 pts with PsO, PsA and AS, with an exposure of 15063.1, 5984.6 and 3527.2 pt-years, respectively) were included. The most frequent AE was upper respiratory tract infection and EAIR per 100 pt-years for IBD, malignancies and MACE remained low. The EAIR per 100 pt-years for adverse events (AEs) of special interest are reported in Table 1. The cumulative post-marketing exposure to SEC was estimated to be ~285,811 pt-years across the approved indications.

Abstract
BACKGROUND To date, there is no effective treatment for thromboangiitis obliterans (TAO). Anlotinib, as a third-line therapy, is recommended for patients with refractory advanced non-small cell lung cancer (NSCLC). We presented a case report of a patient suffering from right lung squamous cell carcinoma combined with thromboangiitis obliterans, and analyzed the treatment dilemma, which provided a new idea for the treatment of these two diseases. METHODS A patient of right lung squamous cell carcinoma complicated with TAO was admitted to the department of respiratory and critical care medicine of the Shanghai General Hospital in August 2018. The diagnosis and treatment was retrospectively analyzed, and the literature was reviewed. RESULTS The 73-year-old male patient complained of cough and sputum for 5 months and was diagnosed with NSCLC (T4N2M0, stage IIIb, performance status score 2) in right upper lung by tracheoscopy biopsy. Pigmentation in both lower extremities accompanied by weakened pulse of dorsal foot artery was confirmed. He had a history of smoking, and suspected vascular intermittent claudication and wandering phlebitis for more than one year. Ultrasound indicated multiple arterial occlusion in both upper and lower extremities and deep venous thrombosis in lower extremities. TAO was diagnosed. Peripherally inserted central catheter (PICC) implantation and intravenous infusion post implantation failed and he could not receive chemotherapy. Vascular endothelial growth factor (VEGF) signal pathway dysfunction is also involved in TAO. Anlotinib (12 mg qd po) was selected for treatment NSCLC and TAO, accordingly. He had partial response (PR) and the cancer kept stable for 14 months. At the same time, TAO improved. CONCLUSIONS Anlotinib effectively controlled the growth of NSCLC and improved TAO related symptoms. Anlotinib maybe normalize disordered growth of blood vessels through the VEGF signaling pathway, rather than simply inhibiting angiogenesis.

Abstract
Abstract
Background
NT-proBNP has diagnostic and prognostic value in patients with heart failure (HF). Compared with enalapril, sacubitril/valsartan (S/V) significantly reduced NT-proBNP within 1 week (wk) of administration and reduced HF re-hospitalisation in patients with acute decompensated HF (ADHF) in PIONEER-HF. Identification of predictors of NT-proBNP reduction with S/V could aid prognostication following hospitalisation.
Methods
TRANSITION (NCT02661217) is an open label study in stabilised ADHF patients with HFrEF that compared S/V initiation pre- versus post-discharge (within 2 wk of discharge). Baseline NT-proBNP was measured at randomisation in both S/V groups (n=950). Clinical predictors of favourable response of NT-proBNP to S/V therapy (defined as reduction to <1000 pg/ml or >30% reduction vs. baseline) were studied at discharge, 4 wk and 10 wk post-randomisation.
Results
Median NT-proBNP at randomisation was similar in patients with S/V started pre- and post-discharge (1919 vs 1659 pg/ml). In patients receiving S/V in-hospital, NT-proBNP was reduced by 28% at discharge, compared to a 3% reduction in patients receiving optimised standard of care (between group p<0.001). A favorable response was reached in 46% vs 18% patients at discharge, 46% vs 42% at 4 weeks and 51% vs 48% at 10 weeks in pre- vs post-discharge groups. (Figure 1). Predictors of favourable NT-proBNP response to S/V at discharge were hypertension and shorter time from admission to first S/V dose. At 4 wk after randomisation, NT-proBNP was reduced similarly in patients started on S/V pre- and post-discharge. When the two S/V initiation groups were combined, predictors of favorable NT-proBNP response at 4 wk were higher initial dose of S/V (≥49/51 mg b.i.d.), higher baseline levels of NT-proBNP, de novo HF hospitalisation, ACEI/ARB naïve, lower baseline creatinine, no atrial fibrillation (AFib), no prior myocardial infarction (MI). A further reduction in NT-proBNP was seen at 10 wk post-randomisation in patients started on S/V pre- and post-discharge (38% vs 34%, between group p=0.250). Predictors of favourable NT-proBNP response to S/V were similar at 4 wk and 10 wk post-randomisation.
Conclusion
In-hospital initiation of sacubitril/valsartan shortly after stabilisation was associated with a prompt improvement of NT-proBNP already at discharge, whereas higher baseline levels of NT-proBNP, higher starting dose, absence of AFib and MI history, de novo HF and ACEI/ARB naïve status were associated with favourable NT-proBNP response in the vulnerable phase after discharge.

Abstract
Abstract
Background
Optimisation of chronic heart failure (HF) therapy remains the key strategy to improve outcomes after hospitalisation for acute decompensated HF (ADHF) with reduced ejection fraction (HFrEF). Initiation and uptitration of disease-modifying therapies is challenging in this vulnerable patient population. We aimed to describe the patterns of treatment optimisation including sacubitril/valsartan (S/V) in the TRANSITION study.

TRANSITION (NCT02661217) was a randomised, open-label study comparing S/V initiation pre- vs. post-discharge (1–14 days) in patients admitted for ADHF after haemodynamic stabilisation. The primary endpoint was the proportion of patients achieving 97/103 mg S/V twice daily (bid) at 10 weeks post-randomisation. Up-titration of S/V was as per label. Information on dose of S/V and on the use of concomitant HF medication was collected at each study visit up to week 26.
Results
A total of 493 patients received at least one dose of S/V in the pre-discharge arm and 489 patients in the post-discharge arm. One month after randomisation, 45% of patients in the pre-d/c arm vs. 44% in the post-discharge arm used 24/26 mg bid starting dose and 42% vs. 40% were on 49/51 mg S/V bid, respectively. At week 10, 47% of patients had achieved the target dose in the pre-discharge arm vs. 51% in the post-discharge arm. At the end of the follow-up at 26 weeks, the proportion of patients on S/V target dose further increased to 53% in the pre-discharge and 61% in the post-discharge arm (Figure 1). At week 10, the mean dose of S/V was 132 mg in the pre-discharge arm and 136 mg in the post-discharge arm, and at week 26, it was 140 mg and 147 mg, respectively.
Before hospital admission, 52% and 54% of the patients received a beta-blocker (BB) in the pre-discharge and post-discharge group, respectively, and 42% in both arms received a mineralcorticoid receptor antagonist (MRA). At time of discharge, 68% and 71%% of the patients received a BB and 68% and 65% an MRA, in the pre-discharge and post-discharge groups, respectively. These proportions remained stable to week 10 and week 26.
Uptitration of sacubitril/valsartan
Conclusions
In the vulnerable post-ADHF population, initiation of S/V and up-titration to target dose was feasible within 10 weeks in half of the patients alongside with a 20% increase in the use of other disease-modifying medications that remained stable through the end of the 6-month follow-up.

Abstract
Abstract
Background
Patients with acute decompensated heart failure (ADHF) are at high risk of recurrent hospitalisations and death. In-hospital initiation of sacubitril/valsartan (S/V) reduced the risk for HF re-hospitalisation by 44% compared to enalapril in the PIONEER-HF study during the 8-week follow-up period. We aimed to describe the pattern of readmissions and their causes in the TRANSITION study, which randomised participants to pre-discharge or post-discharge initation of S/V.
Methods
TRANSITION (NCT02661217) was a randomised, open-label study comparing S/V initiation pre- vs. post-discharge (1–14 days) in haemodynamically stabilised patients with HF with reduced ejection fraction, admitted for ADHF. The primary endpoint was the proportion of patients achieving 97/103 mg S/V twice daily at 10 weeks post-randomisation. Information on rehospitalisation was collected throughout the study up to 26 weeks.
Results
A total of 493 patients received S/V in the pre-discharge arm and 489 patients in the post-discharge arm. Readmissions due to any cause were reported in 9.7% and 18.1% in the pre-discharge arm vs. 10.6% and 21.3% in the post-discharge arm within 30 days, and 10 weeks respectively. During the 26-weeks follow-up, all-cause readmission was reported in 34.5% of patients in the pre-discharge arm vs. 34.6% in the post-discharge arm. Median time to first rehospitalisation was 67 days in the pre-discharge arm (IQR: 26–110 days) and 50 days (IQR: 23–108 days) in the post-discharge arm. At least one HF hospitalisation was reported in 7.5% of patients in the pre-discharge arm and 7.4% in the post-discharge arm during 10 weeks and in 11.8% and 12.3% of patients, respectively, during 26 weeks of follow-up. Median duration of HF readmission was 7 days (IQR: 4–11 days) in the pre-discharge group and 6.5 days (IQR: 6.5–10 days) in the post-discharge arm. In total 2.6% and 5.5% patients in pre-discharge arm and 3.9% and 7% in the post-discharge arm visited an emergency room during 10 weeks and 26 weeks, respectively.
Conclusions
Initiation of S/V in patients hospitalised for ADHF either before or shortly after discharge, results in comparable rates of all cause and HF rehospitalisations, as well as emergency room visits without hospital admission over the 26 week follow-up period. HF re-hospitalisations rates at 10 weeks in TRANSITION are in line with the 8% in S/V arm reported in PIONEER-HF during the 8-weeks follow-up.

Abstract
Background Recent evidence has shown that C-X-C chemokine receptor type 4 (CXCR4) plays a crucial role in acute lung injury (ALI). Macrophages are key factors in the pathogenesis of ALI. The aim of this study was to investigate the role of CXCR4 in macrophages after lipopolysaccharide (LPS) stimulation and confirm that CXCR4 knockdown can inhibit inflammatory cytokines by suppressing mitogen-activated protein kinase (MAPK) and nuclear factor-κB (NF-κB) signaling pathway activation. Results In this study, we found that CXCR4 expression in lung tissue of ALI was significantly increased using immunofluorescence. We also found that the expression of CXCR4 in macrophages sorted from bronchoalveolar lavage fluid (BALF) of ALI was obviously upregulated through RT-qPCR. After CXCR4 knockdown using siRNA, we found that the expression of interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α) was obviously down regulated in macrophages. Additionally, the phosphorylation of p38, Erk, and p65 was significantly decreased after CXCR4 knockdown through western blotting. Conclusions Taken together, the present study suggests that CXCR4 knockdown may inhibit inflammatory cytokine expression in macrophages by suppressing MAPK and NF-κB signaling pathway activation. Therefore, CXCR4 knockdown may have potential clinical value in treating ALI.

Abstract
Previous research has showed that miR-99a-5p was a tumor suppressor. The aim of our study was to explore the effect of miR-99a-5p on the vitality and proliferation, migration together with the invasion of oral tumor cells via inhibiting the expression of NOX4. QRT-PCR and Western blot were applied to examine the expression level of miR-99a-5p and NOX4 in human oral tumorous and adjacent tissues. Dual luciferase reporter gene assay was applied to confirm that miR-99a-5p negatively regulated directly on NOX4 in TSCC1 cells. Cell transfection and lentiviral vectors were used to up-regulate expression of miR-99a-5p and NOX4, respectively. Cell proliferation, cell cycle, apoptosis and invasion along with the migration in different groups were assessed using MTT assay, colony formation assay, the flow cytometry, transwell assay and the wound healing assay, respectively. MiR-99a-5p was under-expressed in human oral tumor, while NOX4 was over-expressed. There was a negative relationship between miR-99a-5p and NOX4. Up-regulating miR-99a-5p or down-regulating NOX4 suppressed the vitality, proliferation, migration together with invasion of TSCC1 cells. MiR-99a-5p affected the vitality and proliferation, migration together with the invasion of oral tumor cells through targeting NOX4.

Abstract
BACKGROUND AND OBJECTIVE Exposure to ozone contributed to the worsening of inflammation and glucocorticoids insensitivity in OVA-challenged asthma. Interleukin-17A participates centrally in stages of the inflammatory response and glucocorticoids insensitivity. In this study, the effect of neutralizing anti-murine interleukin-17A monoclonal antibody (IL-17A mAb) on inflammation and glucocorticoids insensitivity in ozone-exposed and ovalbumin (OVA)-challenged mice was investigated. METHODS Mice were sensitized and challenged with OVA and then exposed to ozone. Dexamethasone (Dex) and IL-17A mAb were administrated in corresponding periods. RESULTS Compared with OVA-challenged mice, combination administration of ozone exposure and OVA challenge increased the recruitment of inflammatory cells in bronchoalveolar lavage fluid, enhanced the inflammation scores and levels of inflammatory cytokines and IL-17A mRNA, and caused the activation of p38 MAPK together with down regulation of glucocorticoids recepters (GR) in lung tissue. Monotherapy of IL-17A mAb partially attenuated lung inflammation in OVA-challenged and ozone-exposed mice, while the combination treatment of Dex and IL-17A mAb effectively reduced lung inflammation, inactivated p38 MAPK and up regulated GR in lung tissue. CONCLUSIONS Ozone exposure worsened OVA-challenged airway inflammation, activation of p38 MAPK and down regulation of GR in OVA-sensitized and -challenged mice, which was effectively counteracted by IL-17A mAb, and combination treatment of IL-17A mAb and Dex shows profound efficacy in inhibiting airway inflammation and improving glucocorticoids insensitivity synergistically.

Abstract
Abstract
Background: In three separate Phase III randomized, placebo-controlled trials, ribociclib (RIB; cyclin-dependent kinase 4/6 inhibitor) + various endocrine therapy (ET) partners prolonged progression-free survival (PFS) vs placebo (PBO) + ET in patients (pts) with hormone receptor-positive (HR+), HER2-negative (HER2–) advanced breast cancer (ABC). Here we further evaluate the efficacy of RIB-based regimens of interest (i.e. with a non-steroidal aromatase inhibitor [NSAI] or fulvestrant [FUL]) in pts who were ET-naïve in the ABC setting, using pooled data from three Phase III trials: MONALEESA (ML)-2 (NCT01958021; all pts), ML-3 (NCT02422615; no prior ET for ABC subgroup only), and ML-7 (NCT02278120; RIB + NSAI subgroup only).
Methods: Postmenopausal pts with no prior ET for ABC received RIB (600 mg/day; 3-weeks-on/1-week-off) or PBO + either letrozole (2.5 mg/day) in ML-2 or FUL (500 mg every 28 days, with an additional dose on Day 15 of Cycle 1) in ML-3. In ML-7, premenopausal pts with no prior ET and ≤1 line of chemotherapy for ABC received RIB or PBO + goserelin (3.6 mg every 28 days) + NSAI (anastrozole [1 mg/day]/letrozole [2.5 mg/day]). The primary endpoint of all three trials was locally assessed PFS. Secondary endpoints included overall response rate (ORR), clinical benefit rate (CBR), and duration of response (DoR; ML-3 and -7). DoR was an exploratory endpoint in ML-2.
Results: Data were pooled for 820 pts treated with RIB + ET (ML-2: n=334; ML-3: n=238; ML-7: n=248) and 710 pts treated with PBO + ET (ML-2: n=334; ML-3: n=129; ML-7: n=247). As of the data cutoffs (ML-2: January 2, 2017; ML-3: November 3, 2017; ML-7: August 20, 2017), in the RIB + ET vs PBO + ET arms, 385 (47%) vs 234 (33%) pts remained on-treatment; the most common reason for discontinuation was disease progression (n=292 [36%] vs n=391 [55%]). In this pooled analysis, median PFS was prolonged for RIB + ET vs PBO + ET, with a hazard ratio of 0.570 (95% confidence interval [CI] 0.491–0.662); median PFS was 25.3 months (95% CI 23.9–29.6) vs 15.6 months (95% CI 14.4–16.9), respectively. Consistent PFS benefit for RIB + ET vs PBO + ET was observed across pt subgroups, including ECOG performance status, age, race, or presence/absence of liver and/or lung metastases or bone-only disease. Among all pts in the pooled analysis, the ORR was 41% for RIB + ET vs 28% for PBO + ET and the CBR was 79% vs 70%, respectively. In pts with measurable disease at baseline (RIB + ET: n=639; PBO + ET: n=542), the ORR was 51% for RIB + ET vs 37% for PBO + ET and the CBR was 79% vs 68%, respectively. In the RIB + ET vs PBO + ET arms, the median DoR was 26.7 months vs 20.0 months. A decrease in best percentage change from baseline in the sum of longest diameters per RECIST was observed in 86% of pts receiving RIB + ET vs 73% of pts receiving PBO + ET.
Conclusions: RIB in combination with various ET partners demonstrates improved clinical outcomes vs PBO + ET across a broad population of pts with HR+, HER2– ABC. These data provide further support for the use of RIB-based combinations in pre- and postmenopausal pts with HR+, HER2– ABC who have received no prior ET for advanced disease.

Abstract
Abstract
Background: In Phase III trials, ribociclib (RIB; cyclin-dependent kinase 4/6 inhibitor) + various endocrine therapy (ET) partners has demonstrated significantly prolonged progression-free survival vs placebo (PBO) + ET in patients (pts) with hormone receptor-positive (HR+), HER2-negative (HER2–) advanced breast cancer (ABC). Here we further evaluate the safety of RIB-based regimens of interest for the proposed indication (i.e. with a non-steroidal aromatase inhibitor [NSAI] or fulvestrant [FUL]) using pooled data from three Phase III trials (MONALEESA [ML]-2 [NCT01958021], -3 [NCT02422615], and -7 [NCT02278120]).
Methods: Postmenopausal pts with HR+, HER2– ABC received RIB (600 mg/day; 3-weeks-on/1-week-off) or PBO + letrozole (LET; 2.5 mg/day; ML-2 [no prior ET for ABC]) or FUL (500 mg, Days 1 and 15 of Cycle 1, then Day 1 of every cycle thereafter; ML-3; no or ≤1 prior line of ET for ABC]). Premenopausal pts (ML-7; no prior ET and ≤1 chemotherapy for ABC]) received RIB or PBO + anastrozole (1 mg/day)/LET (2.5 mg/day) + goserelin (3.6 mg every 28 days). Adverse events (AEs) were characterized per Common Terminology Criteria for Adverse Events v4.03; safety analyses included time to first event, duration of event, and rate of associated RIB/PBO discontinuations.
Results: Data for 1883 pts were pooled; 1065 pts received RIB + ET and 818 pts received PBO + ET (median exposure to study treatment: 17 and 13 months, respectively). Exposure-adjusted incidence rates for AEs of special interest were 561 and 131 per 100 pt-years in the RIB and PBO arms, respectively. The most common all-causality Grade 3/4 AEs (≥10% in any arm; RIB vs PBO) were neutropenia (59% vs 2%), leukopenia (18% vs 1%), and hypertension (13% vs 13%). A new Fridericia's corrected QT interval (QTcF) >480 ms occurred in (n/N) 52/1054 (5%) vs 11/814 (1%) pts in the RIB vs PBO arms; a new QTcF >500 ms occurred in 14/1054 (1%) vs 1/814 (<1%) pts. Median time to first event for Grade ≥2 neutropenia, elevated alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST), and QTc prolongation in the RIB arm was 2, 12, and 2 weeks, respectively; median duration of first Grade ≥2 event was 4, 4, and 2 weeks. In the RIB arm vs PBO arms, 7% vs 3% of pts discontinued study treatment due to AEs; common all-grade AEs leading to RIB/PBO discontinuation (≥2% in any arm) were elevated ALT (4% vs <1%) and elevated AST (2% vs 1%). Discontinuation due to QT prolongation occurred in 4 pts in the RIB arm and 2 in the PBO arm (both <1%). All-grade serious AEs occurred in 25% of pts in the RIB arm vs 15% of pts in the PBO arm.
Conclusions: RIB in combination with various ET partners continues to demonstrate a predictable and manageable tolerability profile across a broad population of pts with HR+, HER2– ABC.

Abstract
AIM To evaluate GI safety of celecoxib compared with 2 nonselective (ns) NSAIDs, as a secondary objective of a large trial examining multiorgan safety. METHODS This randomised, double-blind controlled trial analysed 24 081 patients. Osteoarthritis or rheumatoid arthritis patients, needing ongoing NSAID treatment, were randomised to receive celecoxib 100-200 mg b.d., ibuprofen 600-800 mg t.d.s. or naproxen 375-500 mg b.d. plus esomeprazole, and low-dose aspirin or corticosteroids if already prescribed. Clinically significant GI events (CSGIE-bleeding, obstruction, perforation events from stomach downwards or symptomatic ulcers) and iron deficiency anaemia (IDA) were adjudicated blindly. RESULTS Mean treatment and follow-up durations were 20.3 and 34.1 months. While on treatment or 30 days after, CSGIE occurred in 0.34%, 0.74% and 0.66% taking celecoxib, ibuprofen and naproxen. Hazard ratios (HR) were 0.43 (95% CI 0.27-0.68, P = 0.0003) celecoxib vs ibuprofen and 0.51 (0.32-0.81, P = 0.004) vs naproxen. There was also less IDA on celecoxib: HR 0.43 (0.27-0.68, P = 0.0003) vs ibuprofen; 0.40 (0.25-0.62, P < 0.0001) vs naproxen. Even taken with low-dose aspirin, fewer CSGIE occurred on celecoxib than ibuprofen (HR 0.52 [0.29-0.94], P = 0.03), and less IDA vs naproxen (0.42 [0.23-0.77, P = 0.005]). Corticosteroid use increased total GI events and CSGIE. H. pylori serological status had no influence. CONCLUSIONS Arthritis patients taking NSAIDs plus esomeprazole have infrequent clinically significant gastrointestinal events. Co-prescribed with esomeprazole, celecoxib has better overall GI safety than ibuprofen or naproxen at these doses, despite treatment with low-dose aspirin or corticosteroids.

Abstract
Trichophyton rubrum and T. violaceum are prevalent agents of human dermatophyte infections, the former being found on glabrous skin and nail, while the latter is confined to the scalp. The two species are phenotypically different but are highly similar phylogenetically. The taxonomy of dermatophytes is currently being reconsidered on the basis of molecular phylogeny. Molecular species definitions do not always coincide with existing concepts which are guided by ecological and clinical principles. In this article, we aim to bring phylogenetic and ecological data together in an attempt to develop new species concepts for anthropophilic dermatophytes. Focus is on the T. rubrum complex with analysis of rDNA ITS supplemented with LSU, TUB2, TEF3 and ribosomal protein L10 gene sequences. In order to explore genomic differences between T. rubrum and T. violaceum, one representative for both species was whole genome sequenced. Draft sequences were compared with currently available dermatophyte genomes. Potential virulence factors of adhesins and secreted proteases were predicted and compared phylogenetically. General phylogeny showed clear gaps between geophilic species of Arthroderma, but multilocus distances between species were often very small in the derived anthropophilic and zoophilic genus Trichophyton. Significant genome conservation between T. rubrum and T. violaceum was observed, with a high similarity at the nucleic acid level of 99.38 % identity. Trichophyton violaceum contains more paralogs than T. rubrum. About 30 adhesion genes were predicted among dermatophytes. Seventeen adhesins were common between T. rubrum and T. violaceum, while four were specific for the former and eight for the latter. Phylogenetic analysis of secreted proteases reveals considerable expansion and conservation among the analyzed species. Multilocus phylogeny and genome comparison of T. rubrum and T. violaceum underlined their close affinity. The possibility that they represent a single species exhibiting different phenotypes due to different localizations on the human body is discussed.

Abstract
Background Exposure to ambient ozone (O3) increases the susceptivity to allergens and triggers exacerbations in patients with asthma. However, the detailed mechanisms of action for O3 to trigger asthma exacerbations are still unclear. Methods An ovalbumin (OVA)-established asthmatic mouse model was selected to expose to filtered air (OVA-model) or 1.0 ppm O3 (OVA-O3 model) during the process of OVA challenge. Next, the possible involvements of p38 MAPK and oxidative stress in the ozone actions on the asthma exacerbations were investigated on the mice of OVA-O3 model by treating them with SB239063 (a p38 MAPK inhibitor), and/or the α-tocopherol (antioxidant). Biological measurements were conducted including airway hyperresponsiveness (AHR), airway resistance (Raw), lung compliance (CL), inflammation in the airway lumen and lung parenchyma, the phosphorylation of p38 MAPK and heat shock protein (HSP) 27 in the tracheal tissues, and the malondialdehyde (MDA) content and the glutathione peroxidase (GSH-Px) activity in lung tissues. Results In OVA-allergic mice, O3 exposure deteriorated airway hyperresponsiveness (AHR), airway resistance (Raw), lung compliance (CL) and pulmonary inflammation, accompanied by the increased oxidative stress in lung tissues and promoted p38 MAPK and HSP27 phosphorylation in tracheal tissues. Administration of SB239063 (a p38 MAPK inhibitor) on OVA-O3 model exclusively mitigated the Raw, the CL, and the BAL IL-13 content, while α-tocopherol (antioxidant) differentially reduced the BAL number of eosinophils and macrophages, the content of BAL hyaluronan, the peribronchial inflammation, as well as the mRNA expression of TNF-α and IL-5 in the lung tissues of OVA-O3 model. Administration of these two chemical inhibitors similarly inhibited the AHR, the BAL IFN-γ and IL-6 production, the perivascular lung inflammation and the lung IL-17 mRNA expression of OVA-O3 model. Interestingly, the combined treatment of both compounds together synergistically inhibited neutrophil counts in the BALF and CXCL-1 gene expression in the lung. Conclusions O3 exposure during the OVA challenge process promoted exacerbation in asthma. Both p38 MAPK and oxidative stress were found to play a critical role in this process and simultaneous inhibition of these two pathways significantly reduced the O3-elicited detrimental effects on the asthma exacerbation.

The Value of Fractional Exhaled Nitric Oxide and Forced Mid-Expiratory Flow as Predictive Markers of Bronchial Hyperresponsiveness in Adults with Chronic Cough. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY-IN PRACTICE 2017; 6:1313-1320. [PMID: 29128336 DOI: 10.1016/j.jaip.2017.09.026] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Subscribe] [Scholar Register] [Received: 06/20/2017] [Revised: 09/11/2017] [Accepted: 09/22/2017] [Indexed: 12/22/2022]
Abstract
BACKGROUND Bronchial provocation tests are standard for diagnosing the etiology of chronic cough, but they are time consuming and can induce severe bronchospasm. A safer and faster clinical examination to predict bronchial hyperresponsiveness (BHR) is needed. OBJECTIVE The objective of this study was to investigate whether small-airway function tests can predict BHR in adult patients with chronic cough. METHODS A retrospective, cross-sectional study of diagnoses made using spirometry and bronchial provocation test results was performed in 290 patients with chronic nonproductive cough. BHR-predictive values were analyzed via the area under receiver operating characteristic curves (AUCs). Optimal cutoff values were determined by maximizing the sum of sensitivity and specificity. RESULTS Patients with chronic cough with BHR showed lower forced expiratory flow between 25% and 75% (FEF25%-75%), higher fractional exhaled nitric oxide (FENO), and a higher percentage of eosinophils in blood than patients without BHR (P < .0001 for all). The AUCs of FENO and FEF25%-75% for a BHR diagnosis were 0.788 (95% CI, 0.725-0.851) and 0.702 (95% CI, 0.641-0.763), respectively. Optimal cutoff values were 43 ppb for FENO and 78.5% for FEF25%-75%, with negative predictive values of 85.38% and 81.34%, respectively. The combined use of FENO and FEF25%-75% increased the AUC to 0.843 (95% CI, 0.794-0.892), significantly higher than either FENO (P = .012) or FEF25%-75% (P < .0001) alone. CONCLUSIONS Small-airway dysfunction is present in patients with chronic cough and BHR. FEF25%-75% has value as a negative predictive parameter for BHR, especially when combined with FENO. FENO > 43 ppb and FEF25%-75% < 78.5% strongly predicted a positive bronchial provocation test.
