Relationships Between Chronic Cough and Asthma Control and Quality of Life in Patients With Severe Asthma: A 6-Month Longitudinal Analysis.

The prevalence and clinical implications of chronic cough (CC) in patients with severe asthma receiving asthma treatment remain relatively unknown. This study aimed to evaluate the relationships between CC and asthma control and quality of life (QoL) in patients with severe asthma through longitudinal analysis. Baseline and 6-month follow-up data from the Korean Severe Asthma Registry were analyzed. CC was defined as a cough visual analog scale (VAS) score of ≥40 at both baseline and 6 months. Demographic parameters and clinical outcomes were compared between patients with severe asthma and CC and those without CC. Generalized estimating equation (GEE) analysis was performed to identify associations of CC with asthma control and QoL scores. Of the total 286 participants with severe asthma, 116 (40.6%) were defined as having CC. Patients with CC had higher baseline cough and wheeze severity VAS scores (all P < .001), poorer asthma control (P < .001), and worse QoL (Severe Asthma Questionnaire [SAQ] and Euro-QoL 5-Dimension [EQ-5D] index, all P < .001) than those without CC. During the follow-up, patients with CC were more frequently exposed to oral corticosteroids (58.6% vs 38.6%, P= .010) and experienced more frequent asthma exacerbations (48.3% vs 28.6%, P= .009) than those without CC. GEE analysis revealed that CC was independently associated with poor asthma control, lower SAQ scores, and a lower EQ-5D index after adjusting for confounders. The presence of CC was associated with worse asthma control and QoL in patients with severe asthma. Further studies are warranted to better evaluate and manage CC in these patients.

Exploring Traits Associated With Central Sensitization Features in Patients With Chronic Cough.

The concept of cough hypersensitivity suggests that central sensitization plays a role in the pathophysiology of chronic cough. However, it remains unclear which traits are associated with central sensitization features in patients with chronic cough. A cohort of 317 Korean patients with newly referred chronic cough underwent clinical evaluations. The Central Sensitization Inventory (CSI), a questionnaire originally developed as a screening tool to identify patients with Central Sensitization Syndrome, was also administered. Other patient-reported outcomes (PROs), such as the cough severity visual analogue scale, Leicester Cough Questionnaire (LCQ), Cough Hypersensitivity Questionnaire (CHQ), and the Center for Epidemiological Studies Depression (CES-D) scale, were also administered. Follow-up assessments were conducted one month later. At baseline, the presence of CSI scores of ≥ 40 was associated with being female (89.6% vs. 63.4%; P < 0.001), older age, concomitant symptoms, and cough-related complications. CSI scores correlated with PRO scores, including LCQ (r = -0.424, P < 0.001), CHQ (r = 0.373, P < 0.001), and CES-D (r = -0.660, P < 0.001). Their patterns of correlations were similar in the 1-month longitudinal follow-up data analysis. In conclusion, CSI scores in patients with chronic cough correlated with cough-specific and depression-related PROs, suggesting the potential relevance of central sensitization in certain phenotypes of chronic cough.

The McMaster Cough Severity Questionnaire (MCSQ): a cough severity instrument for patients with refractory chronic cough.

Cough severity represents an important end-point to assess the impact of therapies for patients with refractory chronic cough (RCC). Our objective was to develop a new patient-reported outcome measure addressing cough severity in patients with RCC. Phase 1 (item generation): a systematic survey, focus groups and expert consultation generated 51 items. Phase 2 (item reduction): from a list of 51 items, 100 patients identified those they had experienced in the previous year and rated their importance on a 5-point scale. The McMaster Cough Severity Questionnaire (MCSQ) included items reported to occur most frequently and that had the highest importance scores. Patient feedback on the MCSQ led to elimination of redundant items. Another 100 patients completed the MCSQ, from which we performed an exploratory factor analysis and a Rasch analysis to further refine items on the MCSQ. Previous publications report on the details of Phase 1. Phase 2 led to selection of 15 items from the initial 51. Patient feedback on the 15 items led to elimination of five redundant items. An exploratory factor analysis of the 10-item MCSQ led to the selection of two domains, and the elimination of one item that demonstrated cross-loading and another that had high inter-item correlations. A Rasch analysis of the 8-item MCSQ confirmed that the response options functioned in a logically progressive manner and that no items exhibited differential item functioning. The final 8-item MCSQ has a 1-week recall period and includes two domains (intensity and frequency). The 8-item MCSQ had high internal consistency (Cronbach's α=0.89), proved able to distinguish different levels of cough severity (person separation index 0.89) and demonstrated high cross-sectional convergent validity (Pearson's correlation 0.76, 95% CI 0.66-0.83) with the 100-mm cough severity visual analogue scale. Initial evidence supports the validity of the MCSQ, an 8-item instrument measuring cough severity in patients with RCC. Future studies should evaluate its properties in measuring change over time.

Association Between Smell Loss, Disease Burden, and Dupilumab Efficacy in Chronic Rhinosinusitis with Nasal Polyps.

To evaluate the association between smell loss and other aspects of disease, and evaluate dupilumab efficacy in patients with severe chronic rhinosinusitis with nasal polyps (CRSwNP) and moderate or severe smell loss. This post-hoc analysis of the SINUS-24/52 studies (NCT02912468/NCT02898454) analyzed nasal polyp score (NPS, 0-8), nasal congestion/obstruction (NC, 0-3), Lund-Mackay CT-scan score (LMK-CT, 0-24), rhinosinusitis severity visual analog scale (RS-VAS, 0-10), and 22-item Sinonasal Outcome Test (SNOT-22, 0-110) according to baseline monthly average patient-reported loss of smell scores (LoS, 0-3) of >1 to 2 (moderate) or >2 to 3 (severe) in patients randomized to dupilumab 300 mg or placebo every 2 weeks. Of 724 patients randomized, baseline LoS was severe in 601 (83%) and moderate in 106 (15%). At baseline, severe versus moderate LoS was associated with 1-point greater severity of NC (odds ratio [OR] 6.01 [95% confidence interval, (CI) 3.95, 9.15]), 5-point greater severity of LMK-CT (OR 2.19 [1.69, 2.85]), and 8.9-point greater severity of SNOT-22 (OR 1.35 [1.20, 1.49]). At Week 24, least squares mean differences (95% CI) dupilumab versus placebo in change from baseline were: NPS -1.90 (-2.56, -1.25) and -1.95 (-2.20, -1.70) in the moderate and severe baseline LoS subgroups, respectively; NC -.35 (-.64, -.06) and -1.00 (-1.13, -.87); LMK-CT -6.30 (-7.88, -4.72) and -6.22 (-6.82, -5.63); RS-VAS -1.18 (-2.20, -.16) and -3.47 (-3.90, -3.03); and SNOT-22 -7.52 (-14.55, -.48) and -21.72 (-24.63, -18.82); all nominal P < .05 versus placebo. Improvements with dupilumab in NC, RS-VAS, and SNOT-22 were statistically greater in patients with severe versus moderate baseline LoS. Significant smell impairment in severe CRSwNP is associated with significant disease (NC, RS-VAS, LMK), health-related quality of life impairment (SNOT-22), asthma, and non-steroidal anti-inflammatory drug-exacerbated respiratory disease. Dupilumab significantly improved NPS, NC, LMK-CT, RS-VAS, and SNOT-22 in subjects with moderate and severe baseline smell loss.

Repeat expansions in RFC1 gene in refractory chronic cough.

Refractory chronic cough (RCC), persisting despite addressing contributory diagnoses, is likely underpinned by neurally mediated cough hypersensitivity. RFC1 disorders are genetic neurodegenerative conditions caused by biallelic RFC1 repeat expansion sequences, commonly presenting with cough, followed by neurological features including cerebellar ataxia with neuropathy and vestibular areflexia syndrome (CANVAS). The prevalence and identifying clinical characteristics of RFC1 repeat-expansion disorders in patients with RCC are unknown. Consecutive patients with RCC underwent RFC1 genotyping, cough severity visual analogue scale (VAS) and cough-specific health status assessment (Leicester Cough Questionnaire (LCQ)). Participants with biallelic RFC1 repeat expansions (RFC1++) also underwent nerve conduction studies, brain imaging (MRI) and cough reflex sensitivity testing. 51 participants with RCC were recruited; 36 (71%) female, median (IQR) age 65 (56-70) years, duration of cough 12.8 (6.9-20.0) years. Four (8%) were RFC1++, five (10%) monoallelic carriers (RFC1+-) and 42 (82%) of wild-type genotype (RFC1--). No difference was observed in age, sex, cough duration, spirometry, VAS or LCQ scores between RFC1++ and RFC1-- subjects (p>0.05). The symptom of pins and needles was more frequent in RFC1++ (n=4, 100%) compared to RFC1-- (n=12, 33%) (p=0.01). RFC1++ participants had impaired sensory action potentials, and one had cerebellar atrophy. RFC1++ participants had heightened cough reflex sensitivity to capsaicin, similar to previous CANVAS and RCC studies. Biallelic RFC1 repeat expansions (RFC1++) were present in 8% of RCC patients. RFC1++ participants demonstrated features of cough reflex hypersensitivity. RFC1++ chronic cough had few identifying features, although symptoms of pins and needles were more common.

Risk factors Associated with Pain Severity in Syrian patients with non-specific low back Pain

BackgroundLow back pain (LBP) majorly contributes to activity limitations and work absences worldwide. Therefore, a comprehensive knowledge of the risk factors linked to non-specific low back pain (NSLBP) can enable early and timely interventions to achieve long-term improvements. Current study aimed to assess the risk factors associated with the severity of NSLBP patients in Syria.MethodsThis study used a cross-sectional design and a self-assessment questionnaire to collect data on NSLBP, as well as personal and physical factors, across four provinces in Syria (Damascus, Aleppo, Homs, and Latakia) from November 2021 to September 2022. The assessments incorporated the Short Form 36-Item Health Survey (SF-36), the Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI). Then we examined the relationship between the severity of NSLBP and these potential risk factors. Descriptive statistics were employed to summarize the demographic characteristics of the participants. Additionally, multiple logistic regression analysis was performed to evaluate the risk factors for non-specific low back pain.ResultsThe study included a total of 875 patients with NSLBP. The results indicated that patients with primary school education, a high body mass index (BMI), prolonged driving and sitting durations, smoking habits, and recurrent low back pain had higher VAS and ODI scores, as well as lower SF-36 scores (p < 0.01). Additionally, workers and drivers had higher VAS and ODI scores and lower SF-36 scores compared to waiters and patients who lifted objects heavier than 10 kg for more than a quarter of their work time for over 10 years (p < 0.01). The multiple logistic regression analysis revealed that lower education levels, low back pain lasting 1–7 days, chronic low back pain in the past year, smoking, driving for prolonged time, and higher BMI were associated with more severe VAS scores.ConclusionThe severity of NSLBP is related to lower education levels, poor living conditions, strenuous physical labor, inactive lifestyle, and driving for a long time. Additionally, patients with recurrent NSLBP experience more intense pain. To manage these issues, potential interventions could include reducing obesity rates, limiting the duration of hard physical work, limiting driving duration and reducing sedentary behaviors and smoking. These measures may help alleviate the overall burden of NSLBP.

Efficacy and safety of gefapixant in women with chronic cough and cough-induced stress urinary incontinence: a phase 3b, randomised, multicentre, double-blind, placebo-controlled trial

Approximately two-thirds of women with chronic cough have cough-induced stress urinary incontinence (CSUI). We aimed to evaluate the efficacy and safety of gefapixant in reducing CSUI episodes in women with refractory or unexplained chronic cough. This phase 3b, double-blind, randomised, placebo-controlled trial done at 90 sites in 12 countries enrolled women aged 18 years or older who had chronic cough for at least 1 year, a diagnosis of refractory or unexplained chronic cough, a cough severity visual analogue scale score of 40 mm or more (100 mm maximum), and CSUI for 3 months or more. Participants were randomised 1:1 to oral gefapixant or placebo for 12 weeks. The primary outcome was percentage change from baseline in daily CSUI episodes (7-day average) at week 12. This study is registered with ClinicalTrials.gov (NCT04193176). From May 10, 2020, to Sept 2, 2022, 375 participants were randomised to and treated with gefapixant 45 mg twice daily (n=185) or placebo (n=190). Mean age was 56·4 years (SD 11·4), with mean chronic cough duration of 5·2 years (SD 6·6) and SUI duration of 4·0 years (SD 5·9). Least-squares mean percentage change from baseline in daily CSUI episodes was -52·8% (95% CI -58·4 to -47·1%) for gefapixant and -41·1% (-46·7 to -35·4%) for placebo (estimated treatment difference: -11·7% [95% CI -19·7 to -3·7]; p=0·004). 129 (70%) of 185 participants who received gefapixant and 71 (37%) of 190 participants who received placebo had at least one adverse event. Safety and tolerability were consistent with previous trials of gefapixant; the most frequent adverse events were taste related. Gefapixant 45 mg twice daily is the first treatment to show efficacy versus placebo in reducing CSUI episodes in participants with refractory or unexplained chronic cough.

Cough severity visual analog scale scores and quality of life in patients with refractory or unexplained chronic cough

Refractory chronic cough (RCC) and unexplained chronic cough (UCC) adversely affect patients' quality of life (QoL). This multicenter, non-interventional study evaluates the relationship between cough severity and QoL and other patient-reported outcomes (PROs) in Spanish outpatients. RCC/UCC patients self-administered a printed survey comprising the cough-severity visual analog scale (VAS), adapted Cough Severity Diary (CSD), and Leicester Cough Questionnaire (LCQ), plus purpose-designed items regarding the physical and everyday-life impact of cough. Patients were stratified into VAS score tertiles. The impact of cough on QoL and other PROs in each tertile, and relationships between LCQ scores and the tertiles, were assessed. The VAS was completed by 189 patients, and VAS score tertiles were identified as 0-50, 60-70, and 80-100mm. The only between-tertile difference in demographic or cough characteristics was cough duration. VAS score tertiles were linearly associated with mean LCQ domain and total scores, as well as the proportion of patients with the highest scores on all adapted CSD items, and almost all physical and everyday-life impact items. In multiple linear-regression models, an increase of one tertile in the VAS score was associated with a decrease of 2.23 points in the LCQ total score, indicating poorer cough-related QoL. As self-assessed in patients with RCC/UCC, cough-severity VAS scores were strongly associated with the impact of cough on QoL and everyday life. Patients with VAS scores of 60-100mm reported the greatest impact and thus may benefit the most from targeted cough therapies.

The effects of connective tissue massage and classical massage on pain, lumbar mobility, function, disability, and well-being in chronic low back pain: A three-arm randomized controlled trial

Chronic low back pain (CLBP) is a common musculoskeletal disorder. Effect of massage in the management of CLBP has been documented, but it is not clear which massage regimen is more effective. This study was carried out to compare the effect of connective tissue massage and classical massage on pain, lumbar mobility, function, disability, and well-being among patients with CLBP. The study included 30 participants who were randomly assigned to one of three intervention groups: the connective tissue massage group (CTMG; n = 10), the classical massage group (CMG; n = 10), and a standard physiotherapy/control group (CG; n = 10). The interventions were administered three times a week for four consecutive weeks. Assessments were conducted at baseline and at the end of the fourth week. Pain severity (Visual Analog Scale), lumbar mobility (Modified Schober Test), function (Back Pain Functional Scale), disability (Roland Morris Disability Questionnaire), and well-being (Short Form-36/SF-36) was evaluated. All groups exhibited improvements in pain, lumbar mobility, function, and disability after 4 weeks (p < 0.05). The CMG showed enhancements in physical function, bodily pain, role physical, and role emotional subgroups of SF-36. The CTMG demonstrated improvements in all subgroups of SF-36 except general health (p < 0.05), while the CG only improved in the physical function subgroup (p < 0.05). A 2-way repeated measures ANOVA revealed a significant group-time interaction for MST (p = 0.04), Bodily Pain (p = 0.025) and Role Physical (p = 0.015). The findings obtained from this study showed that CTMG was superior to CMG and CG in increasing lumbar mobility, and both massage applications were superior to the CG in increasing the well-being.

The development of the Cough Hypersensitivity Questionnaire for chronic cough.

Chronic cough is considered a disorder of neuronal hypersensitivity in which patients frequently report abnormal laryngeal and chest sensations, and excessive triggers. To facilitate clinical assessment, we developed the Cough Hypersensitivity Questionnaire (CHQ). Candidate questionnaire items were developed following interviews with patients with refractory chronic cough (n=10, United Kingdom), and review by a multidisciplinary team. The CHQ was evaluated in individuals with chronic cough (n=535, UK/South Korea), for unidimensionality and differential item functioning (with Rasch analysis), internal consistency, concurrent validity (against cough severity visual analogue scale (VAS) and Leicester Cough Questionnaire (LCQ) scores), and content validity (cognitive debriefing interviews, n=13). Concept elicitation created a pool of 34 items. Eleven items were removed following multidisciplinary team review of patient interviews. Rasch analysis confirmed the CHQ total score to be a unidimensional scale; one item was removed due to differential item functioning. The final 22 binary-item CHQ comprises 6 sensation-related and 16 trigger-related items. Median (interquartile range) total CHQ scores were 9 (6-12); sensations 4 (2-5) and triggers 5 (3-8). Internal consistency was good (person separation index 0.74). The CHQ total score was moderately associated with cough severity VAS (0.42, p=0.005) and LCQ total score (ρ=-0.52, p<0.001). In cognitive debriefing, patients found that the CHQ was relevant to their condition and simple to complete. The CHQ is simple to use and has validity for assessing cough triggers and sensations in patients with chronic cough. Further studies are needed to assess its repeatability, responsiveness and clinical utility.

Could cough hypersensitivity symptom profile differentiate phenotypes of chronic cough?

Recently, cough reflex hypersensitivity has been proposed as a common underlying feature of chronic cough in adults. However, symptoms and clinical characteristics of cough hypersensitivity have not been studied amongst phenotypes of chronic cough. This study aimed to compare symptom features, such as cough triggers and associated throat sensations, of cough hypersensitivity in patients with asthmatic chronic cough and those with refractory chronic cough (RCC). Patients with chronic cough from the Korean Chronic Cough Registry were prospectively evaluated over 6 months. Physicians determined the aetiological diagnosis based on clinical evaluations and responses to treatment at the 6-month follow-up visit. Symptoms of cough hypersensitivity and cough-specific quality of life were assessed using the Cough Hypersensitivity Questionnaire (CHQ) and the Leicester Cough Questionnaire (LCQ), respectively. The analysis included 280 patients who completed the follow-up: 79 with asthmatic cough (cough variant asthma or eosinophilic bronchitis) and 201 with RCC. Baseline CHQ scores were similar between the groups (8.3±3.7 in asthmatic cough versus 8.9±3.9 in RCC; p=0.215, adjusted for age, sex and LCQ score). There were no significant between-group differences in the LCQ and cough severity Visual Analog Scale scores. Both groups showed a similar negative correlation with LCQ scores (asthmatic cough: r=-0.427, p<0.001; RCC: r=-0.306, p<0.001). The symptoms of cough hypersensitivity may not distinguish between asthmatic cough and RCC. This suggests that chronic cough is the primary diagnosis in both phenotypes. It indicates a shared mechanism in their cough pathogenesis, despite having potentially different treatable traits.

Burden of Disease Associated with Refractory and Unexplained Chronic Cough in Canada: Results from a National Survey.

Chronic cough (persisting for ≥ 8weeks) is a common disorder that includes refractory chronic cough (RCC; cough that persists despite treatment of underlying disease) and unexplained chronic cough (UCC; cough with no identifiable cause). We evaluated self-reported health-related quality of life (HR-QoL) and work/activity impairment associated with RCC/UCC in Canada. Our exploratory study included Canadians in the Leger Opinion Panel with RCC or UCC. Key entry criteria were ≥ 18years of age, cough for ≥ 8weeks, not currently smoking/quit ≥ 1year ago, no serious respiratory disease or lung cancer, and not taking angiotensin-converting enzyme inhibitors. Respondents completed a 30-min online survey with general and cough-specific HR-QoL questionnaires, including the EuroQol (EQ) visual analogue scale (VAS), EQ-5-dimension 5-level (EQ-5D-5L), cough severity VAS, Leicester Cough Questionnaire (LCQ), and Work Productivity and Activity Impairment-Specific Health Problem (WPAI-SPH). Of 49,076 individuals who completed the chronic cough screening questionnaire (July 30-September 1, 2021), 1,620 (3.3%) met entry criteria for RCC/UCC and 1,046 (2.1%) completed the survey. The mean age of respondents was 45years and 61% were female. Respondents reported impairments in global HR-QoL (EQ-VAS 73.8, 61% with anxiety/depression on the EQ-5D-5L) and cough-specific HR-QoL (mean cough severity VAS score 29.7, LCQ index 15.2). Work and non-work activities were reduced by 34% and 30%, respectively, on the WPAI-SPH. RCC/UCC is prevalent in Canada and associated with impaired HR-QoL, particularly in mental health domains. Additional support and management options may be required to fully address this burden.

Efficacy of apremilast in hyperkeratotic hand and foot dermatitis: results from a randomized observer-blinded comparative study.

Hyperkeratotic hand and foot dermatitis significantly affects quality of life. Some patients respond suboptimally to topical corticosteroids and have multiple recurrences. Our aim was to compare the efficacy and safety profile of apremilast and topical corticosteroid versus corticosteroid alone in hyperkeratotic hand and foot dermatitis. This randomized controlled study involved 77 patients treated for 3 months. GroupA (39 patients) received mometasone furoate 0.1% cream with oral apremilast 30 mg twice daily, and Group B (38 patients) received mometasone alone. They were assessed monthly using the Hand Eczema Clinical Severity Index (HECSI) and Visual Analogue Scale (VAS) scores for pruritus. Investigator Global Assessment (IGA) and Quality of Life in Hand Eczema Questionnaire (QOLHEQ) were conducted at the end of 3 months. The HECSI, VAS score, and QOLHEQ showed a significant decrease in both groups from baseline to the third month. Intergroup comparisons of HECSI failed to reach the significance level. When compared, patients receiving apremilast had significantly better improvement in the third month according to the Patient Global Assessment (PGA) and Investigator Global Assessment (IGA). They also had a smaller number of flares. Adding apremilast to topical corticosteroid leads to better patient and physician-perceived improvement and reduces the number of flares in hyperkeratotic hand eczema.

Exploring the concept of disease control in chronic cough.

Disease control in chronic diseases is an overarching concept that reflects the degree to which the goals of therapy are met. However, to date, there is no consensus on the definition of disease control in chronic cough. This study aimed to provide a conceptual exploration of patient-reported cough control in chronic cough. This research is comprised of two subanalyses. First, patients with chronic cough receiving care at referral clinics were evaluated. Correlation analyses were performed between patient-reported cough control (a 5-point Likert scale), cough-specific patient-reported outcomes (PROs) and generic health PRO scores. Second, a survey was conducted among patients with refractory chronic cough and physicians to identify factors pertinent to cough control. The analysis of 341 patients (mean age: 55.5±15.1 years; female: 66.6%) revealed that cough control rating was moderately correlated with cough severity visual analogue scale and Leicester Cough Questionnaire scores, while demonstrating weaker correlations with cough-associated throat symptoms, cough-related complications or general health-related quality of life (QoL). In the survey of patients and physicians, both groups considered certain factors, such as cough frequency, severity and impact on QoL, to be relevant to the concept of cough control. However, patients rated "need for cough rescue drug" notably higher than physicians. Patient-reported cough control was associated with cough severity or impact on QoL; however, cough control may not be fully captured by conventional cough PRO measurement tools. Further studies are warranted to define the consensus and tools to measure disease control in chronic cough.

Epidemiology and Prognostic Significance of Cough in Fibrotic Interstitial Lung Disease.

Rationale: Cough is a key symptom in patients with fibrotic interstitial lung disease (ILD). Objectives: This study evaluated the prevalence, longitudinal change, associations, and prognostic significance of cough severity in patients with fibrotic ILD. Methods: We included consecutive patients with idiopathic pulmonary fibrosis (IPF) and non-IPF fibrotic ILD who completed the 100-mm Cough Severity Visual Analog Scale from the prospective multicenter Canadian Registry for Pulmonary Fibrosis. Baseline cough severity and associations with patient demographics and clinical factors were determined. Relationships between baseline cough severity and health outcomes were evaluated. Measurements and Main Results: Patients with IPF (n = 1,061) had higher median baseline cough severity than those with non-IPF fibrotic ILD (n = 2,825) (24 vs. 20 mm; P < 0.001), with worse cough associated with gastroesophageal reflux disease for both cohorts. Worse cough severity was independently associated with worse health-related quality of life at baseline, larger annualized decline in DlCO, development of disease progression, and reduced transplant-free survival in both IPF and non-IPF fibrotic ILD cohorts. The IPF cohort (2.2 mm; 95% confidence interval, 1.6-2.9 mm) had larger annualized increments in cough severity than the non-IPF fibrotic ILD cohort (1.1 mm; 95% confidence interval, 0.8-1.4 mm; P = 0.004). There was no difference in worsening cough over time comparing those receiving and not receiving ILD-targeted therapy or with and without lung function decline. Conclusions: Cough is common in patients with IPF and non-IPF fibrotic ILD, with increasing cough severity over time irrespective of ILD-targeted therapy. Patient-reported cough severity has prognostic implications on health-related quality of life, disease progression, and survival in fibrotic ILD.

Endovascular treatment of chronic ilio-femoral vein obstruction with extension below the inguinal ligament in patients with post-thrombotic syndrome

This study aimed to evaluate postoperative outcomes of patients with chronic iliofemoral venous outflow obstruction and post-thrombotic syndrome (PTS) who underwent endovascular recanalization and stenting across the inguinal ligament. All consecutive patients with chronic iliofemoral venous outflow obstruction and PTS were included in the analysis, from January 2018 and February 2022. Preoperative, intraoperative, and postoperative outcomes were assessed. Primary endpoints analyzed were major adverse events (MAEs) at 30days and primary patency rate at 2years of follow-up. Secondary endpoints assessed were secondary patency rate, target vessel revascularization, and clinical improvement evaluated with the Venous Clinical Severity Score (VCSS) classification, Villalta scale, and visual analog scale (VAS), respectively. A total of 63 patients (mean age, 48.1± 15.5years; female, 61.9%) were evaluated. No intraoperative and 30-day postoperative complications were documented. The technical success rate was achieved at 100%. Overall, one in-stent occlusion and five in-stent restenosis were detected during follow-up. The primary patency rate was 93.7% (95% confidence interval [CI], 87.8%-99.9%) and 92.1% (95% CI, 85.6%-99%), at 1- and 2-year follow-up, respectively (Kaplan-Meier analysis). Target vessel revascularization was conducted in two cases, resulting in a secondary patency of 98.4% (95% CI, 95.4%-100%) at 2years of follow-up. Stent fracture and/or migration were not observed during follow-up. A significant clinical improvement in the patient's quality of life was documented. The median improvement of VCSS and Villalta scores were 4 (interquartile range, 2-7; P= .001), and 3 (interquartile range, 1.5-5; P= .001) vs baseline at the last follow-up. Overall, pain reduction of 17mm on the VAS scale was documented at 2years of follow-up. At multivariate analysis, presence of trabeculation into the femoral vein and deep femoral vein (odds ratio, 1.89; 95% CI, 0.15-6.11; P= .043), and Villalta scale >15 points at admission (odds ratio, 1.89; 95% CI, 0.15-6.11; P= .043) were predictive for in-stent occlusion during the follow-up. The use of a dedicated venous stent across the inguinal ligament was safe and effective for the treatment of symptomatic iliofemoral venous disease with acceptable primary and secondary patency rates at 2years of follow-up.

Potassium-Competitive Acid Blocker Versus Proton Pump Inhibitor: A Pilot Study on Comparable Efficacy in the Treatment of Gastroesophageal Reflux-Related Cough.

Acid inhibitors have been considered in treating gastroesophageal reflux-related cough (GERC). Compared to proton pump inhibitors (PPIs), potassium-competitive acid blockers (P-CABs) have more potent and durable effects on anti-acid secretion. However, whether vonoprazan and esomeprazole have different therapeutic effects on GERC remains unknown. Patients diagnosed with GERC were enrolled in our study and randomly treated with vonoprazan (20 mg, once daily, P-CAB) or esomeprazole (20 mg, twice daily, PPI) for two months. A prokinetic agent was also administered. Patients were followed up once a month. Cough severity visual analogue scale (VAS) was measured as the primary outcome, while cough symptom score (CSS) and scores for cough-related quality-of-life or reflux-related symptoms were the secondary endpoints. A total of 50 patients completed the study, with 25 patients in each group. P-CAB and PPI groups showed similar decreases in cough severity VAS and CSS scores after the 2-month treatment (all P < 0.001). For quality-of-life, the Leicester Cough Questionnaire (LCQ) score increased significantly from baseline in both groups, but the P-CAB group had greater improvement and a higher LCQ score in month 2 (all P ≤ 0.05). For reflux-related symptoms, the Hull Airway Reflux Questionnaire (HARQ) score declined substantially over time in the P-CAB group, while the reflux symptom index (RSI) score decreased in both groups. The P-CAB group tended to have a lower HARQ (P = 0.051) and RSI (P = 0.069) scores in month 2. In conclusion, vonoprazan may be comparable to esomeprazole in cough symptom relief in GERC during the 2-month treatment period, but possibly provides better gains on classic reflux symptoms and quality-of-life. The long-term efficacy of P-CABs on GERC may be worth further exploration. Trial Registration: Chinese Clinical Trial Registry Identifier: ChiCTR2200067089.

Dupilumab Treatment Efficacy and Impact on Clinical Scores, Serum Biomarkers, and Itch in Adult Patients with Atopic Dermatitis: A Retrospective Analysis.

Dupilumab, a fully human monoclonal antibody that inhibits the signaling pathways of interleukin (IL)-4 and IL-13, has demonstrated remarkable efficacy in the treatment of atopic dermatitis (AD). Dupilumab has been reported to attenuate itch and reduce several serum markers, including blood lactate dehydrogenase (LDH), blood eosinophil count, and serum total immunoglobulin E (IgE). The present study investigated retrospectively changes in clinical scores and serum biomarker from 175 adults with moderate-to-severe AD treated with dupilumab. Clinical manifestations were assessed using eczema area and severity index (EASI) and visual analogue scale (VAS) for itch at baseline and subsequently at 16-week intervals up to a duration of 48 weeks. Total IgE, LDH and blood eosinophil count were also collected. The dupilumab treatment significantly improved EASI and VAS scores and decreased serum levels of IgE, LDH, and total eosinophil count. The EASI scores were positively correlated with VAS for itch at all recorded time points, whereas serum biomarkers did not exhibit a strong correlation with EASI scores. These findings highlight the close relationship between the extent and severity of eczema and the intensity of itch experienced by patients and suggest that factors beyond the measured serum biomarkers play a significant role in the clinical manifestations of AD, emphasizing the complex nature of the disease.

The correlation between clinical symptom and morphological parameters on magnetic resonance imaging in patients with spondylolisthesis levels L4/L5 and L5/S1.

Spondylolisthesis is one of the common causes of spinal pain. There is currently a lack of studies on the correlation between magnetic resonance imaging (MRI) and clinical symptoms of patients with spondylolisthesis. This study is aimed to find the correlation between clinical symptoms of L4/L5, L5/S1 lumbar spondylolisthesis, and imaging parameters on MRI. A retrospective study on 100 patients who were diagnosed with lumbar spondylolisthesis at the L4/L5, L5/S1 levels from August 2022 to February 2023. Parameters on MRI are measured the cross-sectional area of the dural sac (DSA), the cross-sectional area of the spinal canal (SCA), the ligamentum flavum cross-sectional area (LFA), and ligamentum flavum thickness (LFT), anterior-posterior diameter (APD), sliding distance (SD) at the spondylolisthesis level. Clinical symptoms were investigated according to the Visual Analogue Scale (VAS) for grading of pain and the subjective disability was assessed by the Oswestry Disability Index (ODI). There was no statistically significant difference between SD, APD, SCA, DSA, LFA, and LFT between the mild and moderate pain VAS and severe pain VAS groups. No correlation was found between VAS and SD, APD, SCA, DSA, LFA, and LFT. There is a negative correlation between ODI and APD, SCA, and DSA. The statistically significant difference in APD, SCA, and DSA indexes in the two groups with mild/moderate disability (ODI ≤40%) and the group with severe disability (ODI >40%). A higher DSA and SCA, APD are associated with lower ODI. Decreased APD, SCA, and DSA are all suggestive of decreased spinal function. However, the MRI findings did not correlate with the patient's clinical pain level.

Burden of refractory and unexplained chronic cough on patients' lives: a cohort study.

Chronic cough (cough lasting for ≥8 weeks) can lead to significant impairment in quality of life (QoL). Using patient-reported outcomes, this cohort study assessed the perceived impact of chronic cough on QoL and everyday life in patients from outpatient hospital clinics with refractory chronic cough (RCC) or unexplained chronic cough (UCC). This was a multicentre, non-interventional survey study. Cough severity was assessed on a 0-100 mm Visual Analogue Scale (VAS). Frequency, intensity and disruptiveness of cough were assessed using an adaptation of the Cough Severity Diary. The impact of cough on QoL was assessed using the Leicester Cough Questionnaire (LCQ). The physical impact of cough and associated impact on everyday life activities were explored using purpose-designed questions. 191 patients responded to the survey; 121 (63.4%) had RCC and 149 were women (78.0%). Mean score on the cough severity VAS was 62.9 mm. Mean LCQ total score of 11.9 indicated reduced QoL. Cough impaired patients' everyday life, including the inability to speak fluently (58.0% of patients) and feeling tired/drained (46.6%). Women perceived poorer chronic cough-related QoL than men, as reflected by lower LCQ scores, and greater impairment of physical health, including cough-related stress urinary incontinence, and psychological health. Patients with RCC/UCC experience a significant burden in their everyday life, including impaired QoL, and perceive a negative impact on physical and psychological health and everyday activities, affecting work, relationships and leisure activities. The impact appears to be greater in women than men for several of the aspects studied.
