Managing children with frequent respiratory infections and associated wheezing: a preliminary randomized study with a new multicomponent nasal spray.

BACKGROUND: Preschoolers frequently have respiratory infections (RIs), which may cause wheezing in some subjects. Type 2 polarization may favor increased susceptibility to RIs and associated wheezing. Non-pharmacological remedies are garnering increasing interest as possible add-on therapies. The present preliminary study investigated the efficacy and safety of a new multi-component nasal spray in preschoolers with frequent RIs and associated wheezing. METHODS: Some preschoolers with these characteristics randomly took this product, containing lactoferrin, dipotassium glycyrrhizinate, carboxymethyl-beta-glucan, and vitamins C and D3 (Saflovir), two sprays per nostril twice daily for 3 months. Other children were randomly treated only with standard therapy. Outcomes included the number of RIs and wheezing episodes, use of medications, and severity of clinical manifestations. RESULTS: Preschoolers treated add-on with this multicomponent product experienced fewer RIs and used fewer beta-2 agonists than untreated children (P = 0.01 and 0.029, respectively). CONCLUSIONS: This preliminary study demonstrated that a multicomponent product, administered add-on as a nasal spray, could reduce the incidence of RIs and use of symptomatic drugs for relieving wheezing in children.

Rationale and design of the PARTHENOPE trial: A two-by-two factorial comparison of polymer-free vs biodegradable-polymer drug-eluting stents and personalized vs standard duration of dual antiplatelet therapy in all-comers undergoing PCI.

BACKGROUND: Over the past few decades, percutaneous coronary intervention (PCI) has undergone significant advancements as a result of the combination of device-based and drug-based therapies. These iterations have led to the development of polymer-free drug-eluting stents. However, there is a scarcity of data regarding their clinical performance. Furthermore, while various risk scores have been proposed to determine the optimal duration of dual antiplatelet therapy (DAPT), none of them have undergone prospective validation within the context of randomized trials. DESIGN: The PARTHENOPE trial is a phase IV, prospective, randomized, multicenter, investigator-initiated, assessor-blind study being conducted at 14 centers in Italy (NCT04135989). It includes 2,107 all-comers patients with minimal exclusion criteria, randomly assigned in a 2-by-2 design to receive either the Cre8 amphilimus-eluting stent or the SYNERGY everolimus-eluting stent, along with either a personalized or standard duration of DAPT. Personalized DAPT duration is determined by the DAPT score, which accounts for both bleeding and ischemic risks. Patients with a DAPT score <2 (indicating higher bleeding than ischemic risk) receive DAPT for 3 or 6 months for chronic or acute coronary syndrome, respectively, while patients with a DAPT score ≥2 (indicating higher ischemic than bleeding risk) receive DAPT for 24 months. Patients in the standard DAPT group receive DAPT for 12 months. The trial aims to establish the noninferiority between stents with respect to a device-oriented composite end point of cardiovascular death, target-vessel myocardial infarction, or clinically-driven target-lesion revascularization at 12 months after PCI. Additionally, the trial aims to demonstrate the superiority of personalized DAPT compared to a standard approach with respect to a net clinical composite of all-cause death, any myocardial infarction, stroke, urgent target-vessel revascularization, or type 2 to 5 bleeding according to the Bleeding Academic Research Consortium criteria at 24-months after PCI. SUMMARY: The PARTHENOPE trial is the largest randomized trial investigating the efficacy and safety of a polymer-free DES with a reservoir technology for drug-release and the first trial evaluating a personalized duration of DAPT based on the DAPT score. The study results will provide novel insights into the optimizing the use of drug-eluting stents and DAPT in patients undergoing PCI.

One-year clinical performance of ABSORB bioresorbable vascular scaffold in patients presenting with acute coronary syndromes: Results from the RAI registry.

OBJECTIVES: To report 1-year clinical outcomes of bioresorbable vascular scaffold (BVS) in acute coronary syndromes (ACS) population. BACKGROUND: BVS use has rapidly extended to high-risk patients as those presenting with ACS. To date limited data have been reported on BVS performance in ACS patients. METHODS: RAI is a multicenter, prospective registry that included 1,505 patients treated with at least 1 successful BVS implantation. A subgroup analysis on ACS patients was performed and the 1-year outcomes of this cohort compared to the remaining stable coronary artery disease (SCAD) population are reported here. Coprimary endpoints were target-lesion revascularization (TLR) and scaffold thrombosis (ScT) at 1-year follow-up. RESULTS: Fifty-nine percent of the patients presented with ACS, of whom 36.5% with ST-elevation myocardial infarctions. ACS patients were significantly younger, with a better cardiovascular risk profile, a lower rate of multivessel disease, chronic total occlusion or in-stent restenosis and a lower Syntax score. Predilation and postdilation were performed in 97.4% and in 96.5% of cases, respectively. No differences were noted in terms of TIMI 3 final flow, but acute gain was greater in ACS compared to SCAD group (P < 0.001). At one-year follow-up no differences were found in terms of TLR (3.3% vs. 3.3%, P = 0.98), and device-oriented composite end-point (4.3% vs. 3.4%, P = 0.4) between ACS and SCAD groups. The rate of definite/probable ScT was numerically higher in ACS vs. stable CAD patients (1.3% vs. 0.8%, P = 0.2). CONCLUSIONS: Our data suggest that the use of BVS in ACS patients is associated with a numerically higher rate of ScT compared to SCAD population numerically higher, but without statistical significance.

Absorb bioresorbable vascular scaffold vs. everolimus-eluting metallic stent in small vessel disease: A propensity matched analysis of COMPARE II, RAI, and MAASSTAD-ABSORB studies.

BACKGROUND: Patients with small vessel disease (SVD) are at higher risk of adverse events after PCI compared to non-SVD patients. In this subset, the use of bioresorbable vascular scaffolds (BVS) has raised particular concern. OBJECTIVE: We aimed to compare outcomes of Absorb BVS versus a 2nd-generation metallic everolimus-eluting stents (EES) in the SVD setting, by pooling patients from three large, prospective studies. METHODS: Patients with SVD (reference vessel diameter ≤2.75 mm by QCA) and treated with Absorb BVS were identified in the Italian RAI and the MAASSTAD-Absorb registries. EES controls were identified in the COMPARE II Trial. We performed a propensity-score matching using several clinical and angiographic variables. Implantation technique was not object of matching, being device-specific. RESULTS: Out of 4635 enrolled subjects, 1147 belonged to the SVD population. After matching, we obtained 337 pairs of patients. High clinical and angiographic complexity was found in both groups. Predilation and postdilation rates were significantly higher in BVS patients. No differences were found in terms of the device-oriented composite end-point at 1-year (HR = 1.08, 95%CI 0.5-2.3, P = .8) and 2-years (HR = 1.28, 95% CI: 0.68-2.43, P = .5). Notwithstanding, higher incidence of definite/probable stent thrombosis was observed in the BVS group at 1 year (HR 4.7, 95%CI 0.8-31.4, P = .08) and 2-years (HR = 8.34 95%CI 1.1-60.2, P = .04). CONCLUSION: In this propensity-matched analysis pooling SVD patients of three large prospective studies, incidence of composite device-related events was comparable between BVS and EES up to 2 years follow-up. However, higher rates of stent thrombosis were found in the BVS group.

Bioresorbable vascular scaffold versus everolimus-eluting stents or drug eluting balloon for the treatment of coronary in-stent restenosis: 1-Year follow-up of a propensity score matching comparison (the BIORESOLVE-ISR Study).

OBJECTIVES: to compare the 1-year outcome between bioresorbable vascular scaffold (BVS), everolimus-eluting stent (EES), and drug-eluting balloon (DEB) for in-stent restenosis (ISR) treatment. BACKGROUND: BVS has been proposed as alternative for ISR treatment. To date a direct comparison between BVS and DES or DEB for ISR treatment is lacking. METHODS: We retrospectively analyzed all ISR lesions treated with BVS, DEB, and EES from January 2012 to December 2014. A total of 548 lesions (498 patients) were included. By applying two propensity-score matching, 93 lesions treated with BVS were compared with 93 lesions treated with DEB, and 100 lesions treated with BVS were compared to 100 lesions treated with EES. RESULTS: At 1-year follow-up the incidence of device-oriented cardiovascular events (DOCE) and its components did not significantly differ between BVS and DEB (DOCE: 10.9 vs. 11.8%, HR, 0.91; 95% CI, 0.33-2.52; P = 0.86; Cardiac death: 2.2 vs. 1.2%, HR, 1.74, 95% CI 0.16-18.80, P = 0.65; ID-TLR: 8.9 vs. 10.7%, HR, 0.81, 95% CI 0.27-2.48, P = 0.71; TV-MI: 3.3 vs. 1.2%, HR, 2.39, 95% CI 0.27-21.32, P = 0.43) and BVS vs. EES (DOCE: 10.1 vs. 5.2% HR, 1.81, 95% CI, 0.63-5.25; P = 0.27; Cardiac death: 3.0 vs. 1.1%; HR, 2.83, 95% CI 0.29-27.4, P = 0.37; ID-TLR: 7.2 vs. 4.2%, HR, 1.57, 95% CI 0.47-5.23, P = 0.46; TV-MI: 3.1 vs. 0%). CONCLUSION: At 1-year follow-up the use of BVS as ISR treatment is associated with a higher, even if not significant, DOCE rate compared with EES while a similar rate compared to DEB.

Clinical outcomes of overlapping versus non-overlapping everolimus-eluting absorb bioresorbable vascular scaffolds: An analysis from the multicentre prospective RAI registry (ClinicalTrials.gov identifier: NCT02298413).

OBJECTIVES: To compare clinical outcomes of patients treated with overlapping versus non-overlapping Absorb BVS. BACKGROUND: Limited data are available on the clinical impact of stent overlap with the Absorb BVS bioresorbable stent. METHODS: We compared outcomes of patients receiving overlapping or non-overlapping Absorb BVS in the multicenter prospective RAI Registry. RESULTS: Out of 1,505 consecutive patients treated with Absorb BVS, 1,384 were eligible for this analysis. Of these, 377 (27%) were in the overlap group, and 1,007 (73%) in the non-overlap group. The most frequent overlap configuration was the marker-to-marker type (48%), followed by marker-over-marker (46%) and marker-inside-marker (6%) types. Patients of the overlap group had higher prevalence of multivessel disease and higher SYNTAX score, and required more frequently the use of intravascular imaging. At a median follow-up of 368 days, no difference was observed between overlap and non-overlap groups in terms of a device-related composite endpoint (cardiac death, TV-MI, ID-TLR) (5.8% vs. 4.1%, P = 0.20) or of a patient-related composite endpoint (any death, any MI, any revascularization) (15.4% vs. 12.5%, P = 0.18). Cardiac death (1.0% vs. 1.3%, P = 0.54), MI (4.5% vs. 3.6%, P = 0.51), TVR (4.5% vs. 3.6%, P = 0.51) and stent thrombosis (1.1 vs. 1.5%, P = 1.00) were also comparable between groups. When assessing outcomes of the overlap population according to overlap configurations used, no difference was observed in terms of the device- or patient-related composite endpoints. CONCLUSIONS: Outcomes of patients with or without overlapping BVS were comparable at mid-term follow-up despite higher angiographic complexity of the overlap subset. © 2017 Wiley Periodicals, Inc.

A prospective evaluation of a standardized strategy for the use of a polymeric everolimus-eluting bioresorbable scaffold in ST-segment elevation myocardial infarction: Rationale and design of the BVS STEMI STRATEGY-IT study.

OBJECTIVES: To assess the feasibility and the clinical results following a prespecified bioresorbable vascular scaffold (Absorb BVS) implantation strategy in ST-elevation myocardial infarction (STEMI) patients. BACKGROUNDS: Concerns raised about the BVS safety in STEMI setting because a not negligible thrombosis rate was reported within 30 days and 12 months after implantation. Technical procedural issues related to the structural BVS features were advocated as probable causes for the thrombotic events. METHODS: This is an investigators-owned and -directed, prospective, nonrandomized, single-arm multicenter registry intended to obtain data from 500 consecutive STEMI patients undergoing primary PCI with BVS (1.1 or GT1) following a prespecified implantation protocol. The study is recorded in ClinicalTrials.gov with the identifier: NCT02601781. RESULTS: The primary endpoint is a device-oriented composite end-point (DOCE) of cardiac death, any myocardial infarction clearly attributable to the intervention culprit vessel and ischemic-driven target lesion revascularization within 30 days after the index procedure. The DOCE will be assessed even at 6-month, 1-, 3-, and 5-year follow-up. CONCLUSIONS: This will be the first study investigating the feasibility and the early- and long-term clinical impact of a prespecified BVS implantation protocol in thrombotic lesions causing STEMI. Here, we describe the rationale and the design of the study. © 2016 Wiley Periodicals, Inc.

Bioresorbable vascular scaffolds for small vessels coronary disease: The BVS-save registry.

OBJECTIVE: In this study, we investigated long-term results following bioresorbable vascular scaffold (BVS) implantation in small coronary arteries. BACKGROUND: Management of small coronary vessel disease with percutaneous coronary interventions (PCI) is often associated with high recurrencies and an increased risk of late or very late adverse events. Currently, little is known about BVS behavior in this setting. METHODS: A retrospective cohort analysis in a consecutive all-comer population was performed in patients that had a BVS implanted for coronary artery disease (CAD) in vessels with reference diameter <2.75 mm. Primary end-point was the occurrence of BVS failure (any event between target lesion revascularization (TLR) and definite/probable thrombosis) at the longest available follow-up. Secondary end-points were device-oriented clinical outcome (DOCE, a composite of cardiac death, target-vessel non-fatal myocardial infarction (MI) and TLR) and its single components at 12-month follow-up. RESULTS: A total of 121 patients (133 lesions) were treated between March 2013 and December 2014 at three high volume Italian centers. From baseline clinical and angiographic characteristics emerges a highly complex patient population. Procedural success was obtained in 120 (99.2%) patients. In-hospital events included one cardiac death. At the longest available clinical follow-up (average 12 ± 6, median 11.4 months, interquartile ranges (IQR) 8, primary end-point occurred in 12 patients (9.0%), including 12 (9.0%) TLR and 2 (1.5%) BVS thrombosis. DOCE occurred in 9.0% of cases. The use of overlapping BVS in this setting did not increase the risk of adverse events. CONCLUSIONS: BVS implantation in a highly complex clinical and angiographic setting of small coronary vessels was technically feasible and effective in maintaining vessel patency after 12 months. © 2016 Wiley Periodicals, Inc.

Attitude to food supplement use: a survey promoted by the Italian Society of Pediatric Allergy and Immunology.

Food supplements are defined as foodstuffs the purpose of which is to supplement the normal diet and which are concentrated sources of nutrients or other substances with a nutritional or physiological effect, often referred to as nutraceuticals, may exert benefit to the human body. Their use is increasing worldwide, including Europe and in Italy. However, some doctors are skeptical about their effectiveness and safety. This reluctance may depend on poor knowledge of the mechanisms of action and clinical evidence in literature. The Italian Society of Pediatric Allergy and Immunology (SIAIP) promoted the institution of an ad hoc Committee. The first initiative performed by this Committee was the administration of a questionnaire to the members of SIAIP.The results of this survey provided interesting results. Most pediatricians know the food supplement concept but frequently need help understanding the mechanisms of action. Most prescribe food supplements, mainly for preventing infections or enhancing immune defense. In addition, they prefer to use food supplements as cycles or add-on therapy. Finally, most participants like to attend events on this issue and contribute to new evidence through trials.In conclusion, this survey underscores the relevance of food supplement issues and attests to interest in this topic. However, there is a need to provide information and promote studies on this matter.

Exploring the Role of Lactoferrin in Managing Allergic Airway Diseases among Children: Unrevealing a Potential Breakthrough.

The prevalence of allergic diseases has dramatically increased among children in recent decades. These conditions significantly impact the quality of life of allergic children and their families. Lactoferrin, a multifunctional glycoprotein found in various biological fluids, is emerging as a promising immunomodulatory agent that can potentially alleviate allergic diseases in children. Lactoferrin's multifaceted properties make it a compelling candidate for managing these conditions. Firstly, lactoferrin exhibits potent anti-inflammatory and antioxidant activities, which can mitigate the chronic inflammation characteristic of allergic diseases. Secondly, its iron-binding capabilities may help regulate the iron balance in allergic children, potentially influencing the severity of their symptoms. Lactoferrin also demonstrates antimicrobial properties, making it beneficial in preventing secondary infections often associated with respiratory allergies. Furthermore, its ability to modulate the immune response and regulate inflammatory pathways suggests its potential as an immune-balancing agent. This review of the current literature emphasises the need for further research to elucidate the precise roles of lactoferrin in allergic diseases. Harnessing the immunomodulatory potential of lactoferrin could provide a novel add-on approach to managing allergic diseases in children, offering hope for improved outcomes and an enhanced quality of life for paediatric patients and their families. As lactoferrin continues to capture the attention of researchers, its properties and diverse applications make it an intriguing subject of study with a rich history and a promising future.

Choosing nasal devices: a dilemma in clinical practice.

BACKGROUND AND AIM: Upper airway diseases are frequent and recognize different etiopathogenetic mechanisms, including infection, inflammation, and allergy. Therefore, topical treatments are preferable in comparison with systemic medications. Several delivery devices are available on the market, including nasal drops, syringes, sprays, nebulizers, and douches. However, it is clinically relevant to know the better way to use it. METHODS: The present experience compared five different devices that were tested: i) a nasal dropper, ii) a standard nasal spray device, iii) a mucosal atomization device with a nozzle tip, iv) a nebulizer device, and v) a nasal douche. Saline solution with methylene blue was the marker to evaluate the intranasal distribution. RESULTS: The findings showed an apparent difference in area distribution among these delivery devices. Conclusion The present experience showed that doctors should choose the most appropriate device for the current disease in clinical practice.

When rhinosinusitis is not just rhinosinusitis: Clinical characteristics and phenotypes of patients with type 2 chronic rhinosinusitis with nasal polyps.

BACKGROUND AND AIM: Chronic rhinosinusitis (CRS) is a chronic and recurrent disease that negatively affects patients' quality of life. CRS has two main phenotypes: CRS with nasal polyps (CRSwNP) and CRS without polyps (CRSsNP). Minimal research has been conducted to study the variability in patients' characteristics. Therefore, we conducted this study to examine these differences. METHODS: A retrospective cohort study included patients with both CRSwNP and CRSsNP. Outcomes included symptom severity, radiographic severity, and number of sinus surgeries. Symptom severity was assessed using the Sino-nasal Outcome Test and the Lund-Mackay CT score was used to determine radiographic severity. Further subgroup analysis was done based on the presence or absence of comorbid asthma. RESULTS: A total of 110 and 106 patients were included in the CRSwNP and CRSsNP groups, respectively. The mean age in the CRSwNP and CRSsNP groups was 50.2 and 48.7, and the proportion of female patients was 40.9% and 58.5%, respectively. No significant difference in symptom severity was noted between CRSwNP and CRSsNP group (68.1±18.6 vs. 73.2±21.27; P=0.097), while the Lund-Mackay score was significantly lower in the CRSsNP group (7.4±2.3 vs. 11.9±3.6; P=0.016). Also, the number of surgeries was significantly lower in the CRSsNP group as compared to the CRSwNP group (P=0.023). Subgroup analysis revealed statistically significant differences between those with and without asthma in patients with CRSwNP in terms of Lund-Mackay scores and number of surgeries (P=0.038 and 0.043), respectively. However, no significant differences were noted in the CRSsNP group (P>0.05). CONCLUSIONS: There is a clear variability in the characteristics of patients with CRSsNP and CRSwNP. A similar difference was noted in the CRSwNP group when patients were stratified based on the presence of absence of asthma. This warrants further investigation of potential correlation with the prognosis and optimum treatment strategies of this patient population.

ImpaCt of an Optimal Implantation Strategy on Absorb Long-Term Outcomes: The CIAO Registry.

AIM: To compare the long-term outcomes of patients implanted with Absorb bioresorbable scaffold (BRS) with optimal versus suboptimal technique. METHODS AND RESULTS: All patients who received an Absorb between March 2012 and January 2016 were selected from 19 Italian centers databases to assess the impact of an optimal implantation technique (CIAO criteria) on long-term device-oriented composite end-point (DOCE) - including cardiac death (CD), target-vessel myocardial infarction (TV-MI) and ischemia-driven target lesion revascularization (ID-TLR) - on its single components and on scaffold thrombosis (ScT). CIAO criteria consist of predilation (balloon/vessel ratio 1:1), correct sizing (BRS/proximal reference vessel diameter -RVD- ratio 0.8-1.2) and high-pressure postdilation with non-compliant (NC) balloon (≥20 atm for balloon/BRS ratio 1:1 or ≥16 atm for a 0.25-0.5 mm oversized balloon). Among the 1.434 patients analyzed, 464 (32.4%) fulfilled all CIAO criteria for every BRS implanted (CIAO 3 group), while 970 (67.6%) did not in at least one of the received BRS (CIAO 0-1-2 group). At 31.0 (interquartile range -IQR- 24.8-38.5) months follow-up, CIAO criteria did not impact on DOCE (8.2% vs. 8.0%, p = 0.92), ID-TLR (6.9% vs. 7.1%, p = 0.72) or ScT (1.9% vs. 1.8%, p = 0.80) in the overall population. At multivariate analysis overall BRS length (p = 0.001), severely calcified lesions (p = 0.03) and absence of CIAO criteria (CIAO 0, p = 0.005) were independent predictors of DOCE in long-term follow-up. CONCLUSION: Our data suggest that strict application of an optimal Absorb implantation technique doesn't improve long-term DOCE or ScT but may mitigate the worse outcome of patients with calcific lesions.

Prevention of recurrent respiratory infections : Inter-society Consensus.

Recurrent respiratory infections (RRIs) are a common clinical condition in children, in fact about 25% of children under 1 year and 6% of children during the first 6 years of life have RRIs. In most cases, infections occur with mild clinical manifestations and the frequency of episodes tends to decrease over time with a complete resolution by 12 years of age. However, RRIs significantly reduce child and family quality of life and lead to significant medical and social costs.Despite the importance of this condition, there is currently no agreed definition of the term RRIs in the literature, especially concerning the frequency and type of infectious episodes to be considered. The aim of this consensus document is to propose an updated definition and provide recommendations with the intent of guiding the physician in the complex process of diagnosis, management and prevention of RRIs.

Inter-society consensus for the use of inhaled corticosteroids in infants, children and adolescents with airway diseases.

BACKGROUND: In 2019, a multidisciplinary panel of experts from eight Italian scientific paediatric societies developed a consensus document for the use of inhaled corticosteroids in the management and prevention of the most common paediatric airways disorders. The aim is to provide healthcare providers with a multidisciplinary document including indications useful in the clinical practice. The consensus document was intended to be addressed to paediatricians who work in the Paediatric Divisions, the Primary Care Services and the Emergency Departments, as well as to Residents or PhD students, paediatric nurses and specialists or consultants in paediatric pulmonology, allergy, infectious diseases, and ear, nose, and throat medicine. METHODS: Clinical questions identifying Population, Intervention(s), Comparison and Outcome(s) were addressed by methodologists and a general agreement on the topics and the strength of the recommendations (according to the GRADE system) was obtained following the Delphi method. The literature selection included secondary sources such as evidence-based guidelines and systematic reviews and was integrated with primary studies subsequently published. RESULTS: The expert panel provided a number of recommendations on the use of inhaled corticosteroids in preschool wheezing, bronchial asthma, allergic and non-allergic rhinitis, acute and chronic rhinosinusitis, adenoid hypertrophy, laryngitis and laryngospasm. CONCLUSIONS: We provided a multidisciplinary update on the current recommendations for the management and prevention of the most common paediatric airways disorders requiring inhaled corticosteroids, in order to share useful indications, identify gaps in knowledge and drive future research.

Long-Term outcome of drug-eluting stents compared with bare metal stents in ST-segment elevation myocardial infarction: results of the paclitaxel- or sirolimus-eluting stent versus bare metal stent in Primary Angioplasty (PASEO) Randomized Trial.

BACKGROUND: Drug-eluting stents may offer benefits in terms of repeat revascularization that may be counterbalanced by a potential higher risk of stent thrombosis, especially among ST-segment elevation myocardial infarction (STEMI) patients. No data have been reported so far on the long-term benefits and safety of drug-eluting stents in STEMI. Thus, the aim of the present study was to evaluate the short- and long-term benefits of sirolimus-eluting stents (SES) and paclitaxel-eluting stents (PES) compared with bare metal stents (BMS) in patients undergoing primary angioplasty. METHODS AND RESULTS: Consecutive STEMI patients admitted within 12 hours of symptom onset and undergoing primary angioplasty and stent implantation at a tertiary center with 24-hour primary percutaneous coronary intervention capability were randomly assigned to BMS, PES, or SES. All patients received upstream glycoprotein IIb/IIIa inhibitors. The primary end point was target lesion revascularization at the 1-year follow-up. Secondary end points were death and/or reinfarction, in-stent thrombosis, and major adverse cardiac events (combined death and/or reinfarction and/or target lesion revascularization) at long-term follow-up (up to 4 to 6 years). Cumulative incidence of end points was investigated. No patient was lost to follow-up. From October 1, 2003, to December 31, 2005, 270 patients with STEMI were randomized to BMS (n=90), PES (n=90), or SES (n=90). Procedural success was obtained in 93% to 95% of patients. Follow-up data were available for all patients. Compared with BMS (14.4%), both PES (4.4%; hazard ratio, 0.29; 95% confidence interval, 0.095 to 0.89; P=0.023) and SES (3.3%; hazard ratio, 0.21; 95% confidence interval, 0.06 to 0.75; P=0.016) were associated with a significant reduction in target lesion revascularization at the 1-year follow-up (primary study end point). At the long-term follow-up (4.3 years; 25th to 75th percentile, 3.7 to 5 years), no difference was observed in terms of death, reinfarction, and combined death and/or reinfarction, but compared with BMS (22.2%), both PES (6.7%; hazard ratio, 0.27; 95% confidence interval, 0.11 to 0.68; P=0.005) and SES (5.6%; hazard ratio, 0.22; 95% confidence interval, 0.083 to 0.59; P=0.003) were associated with a significant reduction in target lesion revascularization. CONCLUSIONS: This study shows that among STEMI patients undergoing primary angioplasty, both SES and PES are associated with significant benefits in terms of target lesion revascularization at the long-term follow-up compared with BMS with no excess risk of thrombotic complications. Thus, until the results of further large randomized trials with long-term follow-up become available, drug-eluting stents may be considered among STEMI patients undergoing primary angioplasty.

Impact of diabetes on long-term outcome in STEMI patients undergoing primary angioplasty with glycoprotein IIb-IIIa inhibitors and BMS or DES.

Diabetes has been shown to be associated with worse survival and repeat revascularization (TVR) after primary angioplasty. Drug-eluting stent (DES) may offer benefits in terms of TVR, that may be counterbalanced by an higher risk of stent thrombosis, especially among STEMI patients. Aim of the current study was to evaluate the impact of diabetes on 5-year outcome in patients undergoing primary angioplasty with glycoprotein IIb-IIIa inhibitors in the era of DES. Our population is represented by STEMI patients undergoing primary angioplasty and stent implantation at a tertiary center with 24-h primary PCI capability within 12 h of symptom onset. All patients received glycoprotein IIb-IIIa inhibitors. No patient was lost to follow up. From 2003 to 2005, 270 STEMI patients were treated with DES (n = 180), or BMS (n = 90). A total of 69 patients had history of diabetes at admission (25.5%). At a follow-up of 1510 +/- 406 days, diabetes was associated with a higher rate of death (29.5 vs. 5.1%, P < 0.0001), reinfarction (24.1 vs. 9.1%, P < 0.0001), TVR (19.1 vs. 13.1%, P = 0.052), IST (17.2 vs. 6.8%, P < 0.001) and MACE (51.9 vs. 25.1%, P < 0.001). These results were confirmed in both patients receiving BMS or DES, except for TVR, where no difference was observed between diabetic and non-diabetic patients. This study shows that among STEMI patients undergoing primary angioplasty with Gp IIb-IIIa inhibitors, diabetes is associated with worse long-term mortality, reinfarction, and IST, even with DES implantation, that, however, were able to equalize the outcome in terms of TVR as compared to non diabetic patients.

Inflammation, infection, and allergy of upper airways: new insights from national and real-world studies.

The upper airways (UA) should be considered as a functional unit. Current functional anatomy divides URT in three, mutually dependent, "junction boxes": i) the ostio-meatal complex (OMC), ii) the spheno-ethmoidal recess (SER), and iii) the rhinopharynx (RP). Correct ventilation and effective mucociliary clearance of these sites significantly affect the healthy physiology of the entire respiratory system. The OMC, SER, and RP obstruction is the first pathogenic step in the inflammatory/infectious cascade of UA disorders. The inflammation of the respiratory mucosa is the main pathogenic factor for airway obstruction. Moreover, bacterial biofilm (a strategy modality of bacterial survival) is an important local cause of systemic antibiotic ineffectiveness, recurrent infections, and antibiotic resistance. Health microbiota guarantees UA wellness; on the contrary, dysbiosis promotes and worsens UA infections. Allergy, namely type 2 inflammation, is a common cause of UA obstruction such as promoting in turn infections. Fiberoptic endoscopy is a mandatory diagnostic tool in clinical practice. Nasal cytology, mainly concerning flow cytometry, allows defining rhinitis phenotypes so allowing a precision medicine approach. Several conventional therapeutic approaches are available, but efficacy and safety should be ever properly considered before the prescription. Also, complementary medicine plays a fruitful role in the management of UA diseases. National and real-world studies are reported and discussed as they may be useful in daily clinical practice.

Benefits of drug-eluting stents as compared to bare metal stent in ST-segment elevation myocardial infarction: four year results of the PaclitAxel or Sirolimus-Eluting stent vs bare metal stent in primary angiOplasty (PASEO) randomized trial.

BACKGROUND: Drug-eluting stent (DES) may offer benefits in terms of repeat revascularization, which may be counterbalanced by a potential higher risk of stent thrombosis, especially among patients with STEMI. No data have been reported so far on the long-term benefits and safety of DES in STEMI. The aim of the current study was to evaluate the short- and long-term benefits of sirolimus-eluting stent (SES) and paclitaxel-eluting stent (PES) as compared to bare-metal stent (BMS) in patients undergoing primary angioplasty. METHODS: Consecutive patients with STEMI admitted within 12 hours of symptom onset and undergoing primary angioplasty and stent implantation at a tertiary center with 24-hour primary percutaneous coronary intervention capability were randomly assigned to BMS, PES, and SES. All patients received upstream glycoprotein IIb-IIIa inhibitors. Primary end point was target-lesion revascularization at 1-year follow-up. Secondary end points were (1) cumulative combined incidence of death and/or reinfarction; (2) cumulative incidence of in-stent thrombosis; and (3) major adverse cardiac events (MACE) (combined death and/or reinfarction and/or target lesion revascularization [TLR]) at long-term follow-up (up to 4 years). No patient was lost to follow-up. RESULTS: From October 1, 2003, to December 2005, 270 patients with STEMI were randomized to BMS (n = 90), PES (n = 90), or SES (n = 90). Procedural success was obtained in 93% to 95% of patients. Follow-up data were available for all patients. As compared to BMS (14.4%), both PES (4.4%, hazard ratio [HR] 0.29, 95% CI 0.095-0.89, P = .023) and SES (3.3%, HR 0.21, 95% CI 0.06-0.75, P = .016) were associated with a significant reduction in TLR at 1-year follow-up (primary study end point). At long-term follow-up (1,233 +/- 215 days), no difference was observed in terms of death, reinfarction, and combined death and/or reinfarction, but as compared to BMS (21.1%), both PES (6.7%, HR 0.29, 95% CI 0.12-0.73, P = .008) and SES (5.6%, HR 0.24, 95% CI 0.09-0.63, P = .002), respectively, were associated with a significant reduction in TLR. CONCLUSIONS: This study shows that among patients with STEMI undergoing primary angioplasty, both SES and PES are safe and associated with significant benefits in terms of TLR up to 4 years' follow-up, as compared to BMS. Thus, until the results of further large randomized trials with long-term follow-up become available, DES may be considered among patients with STEMI undergoing primary angioplasty.
