Project description:BackgroundAngiogenesis has been implicated in the pathogenesis of idiopathic interstitial pneumonia (IIP). The aim of this study was to examine the relationship between plasma concentrations of the angiogenic cytokines interleukin 8 (IL-8), vascular endothelial growth factor (VEGF), and endothelin-1 (ET-1) and clinical parameters of disease progression over a 6 month period to identify potential aetiological mediators and prognostic markers of disease activity in patients with IIP.MethodsForty nine patients with IIP (40 men) were recruited to the study. Plasma cytokine measurements, pulmonary function tests, and high resolution computed tomography (HRCT) scans were performed on recruitment and after 6 months. Plasma cytokine measurements were also performed in 15 healthy volunteers for control purposes.ResultsPatients with IIP had significantly higher median (IQR) baseline concentrations of IL-8 and ET-1 than controls (155 (77-303) pg/ml v 31 (0-100) pg/ml, p<0.001) and (1.21 (0.91-1.88) pg/ml v 0.84 (0.67-1.13) pg/ml, p<0.01), respectively. Baseline concentrations of IL-8, ET-1, and VEGF were significantly related to the baseline HRCT fibrosis score (r = 0.42, p<0.005; r = 0.39, p<0.01; and r = 0.42, p<0.005, respectively). Patients with IIP who developed progressive disease had significantly higher baseline levels of IL-8 (345 (270-497) pg/ml v 121 (73-266) pg/ml, p = 0.001) and VEGF (1048 (666-2149) pg/ml v 658 (438-837) pg/ml, p = 0.019). Over 6 months the change in VEGF was significantly related to the change in HRCT fibrosis score (r = 0.565, p = 0.035) and negatively related to the change in forced vital capacity (r = -0.353, p = 0.035).

Project description:IntroductionMain clinical manifestations of SARS-CoV-2 infection are characterized by fever, dyspnea, and interstitial pneumonia, frequently evolving in acute respiratory distress syndrome (ARDS).Areas coveredFeatures of coronavirus disease 2019 (COVID-19) presents some common points with interstitial lung disease (ILD) both idiopathic and related to rheumatoid arthritis (RA), typically characterized by a chronic progression over time and possibly complicated by acute exacerbation (AE). The study of common pathogenetic mechanisms, such as the involvement of toll-like receptor 4, could contribute to the knowledge and treatment of idiopathic and RA-ILD. Moreover, hyperinflammation, mainly characterized by increase of effector T-cells and inflammatory cytokines, and activation of coagulation cascade, observed in COVID-19 related ARDS have been already shown in patients with AE of idiopathic and RA-ILD. A literature search was performed in PubMed, Embase, Scopus, and Web of Science, together with a manual search in COVID-resource centers of the main journals.Expert opinionDespite the uncertainty about pathogenetic aspects about COVID-19- pneumonia, it could be a possible model for other forms of ILD and AE. The great amount of data from studies on COVID-19 could be helpful in proposing safe therapeutic approaches for RA-ILD, in understanding pathogenesis of usual interstitial pneumonia and to develop new therapeutic strategies for AE.

Project description:BackgroundIdiopathic non-specific interstitial pneumonia (iNSIP), idiopathic pleuroparenchymal fibroelastosis (iPPFE), and unclassifiable idiopathic interstitial pneumonia (IIP) are IIPs with chronic fibrotic phenotypes, and unlike idiopathic pulmonary fibrosis, they have often been treated with anti-inflammatory drugs, including corticosteroids and immunosuppressants. However, the impact of bronchoalveolar lavage (BAL) lymphocytosis on the effects of anti-inflammatory therapy has never been evaluated. This study aimed to elucidate whether BAL lymphocytosis can be used to predict the efficacy of anti-inflammatory drugs for iNSIP, iPPFE, and unclassifiable IIP.MethodsJapanese patients diagnosed with iNSIP, iPPFE, and unclassifiable IIP by multidisciplinary discussion were identified using the nationwide registry. Eligible patients were stratified into four groups with and without BAL lymphocytosis and anti-inflammatory therapy to compare overall survival (OS) and changes in lung function. BAL lymphocytosis was defined as a lymphocyte differential count > 15%, and the cut-off was corroborated by survival classification and regression tree analysis.ResultsOverall, 186 patients (37 iNSIP, 16 iPPFE, and 133 unclassifiable IIP) were analyzed. Limited to patients treated with anti-inflammatory drugs (n = 123), patients with BAL lymphocytosis had a better prognosis [hazard ratio (HR), 0.26; 95% confidence interval (CI), 0.11-0.63; P = 0.003], higher slope of forced vital capacity (FVC) % predicted for 2 years, and longer OS (log-rank test, P = 0.012) than those without BAL lymphocytosis. On multivariate analysis, BAL lymphocytosis (HR 0.31; 95% CI 0.13-0.75; P = 0.009) was a prognostic factor for OS, along with age and FVC % predicted. Conversely, for patients managed without anti-inflammatory therapy (n = 63), the presence or absence of BAL lymphocytosis had no prognostic value.ConclusionsBAL lymphocytosis is associated with good outcomes in patients treated with anti-inflammatory drugs, but has no prognostic value when anti-inflammatory drugs are not used. BAL lymphocytosis may provide a predictive biomarker for identifying patients with iNSIP, iPPFE and unclassifiable IIP who are likely to benefit from anti-inflammatory drugs.

Project description:BackgroundCases of spontaneous pneumothorax have been described in patients suffering from coronavirus disease 2019 (COVID-19) pneumonia. The aim of this study is to systematically review all the cases of spontaneous pneumothorax that occurred in healthy patients with no underlying lung disease and who did not receive invasive mechanical ventilation.MethodsA PubMed research was conducted. The following data were collected: age, sex, side of the pneumothorax, smoking habit, time form onset of symptoms to the diagnosis of pneumothorax, the development of new bullous lesions on computed tomography and the type of treatment. In order to analyze the most homogeneous population possible, intubated patients were deliberately excluded. In total, 44 cases of spontaneous pneumothorax in otherwise healthy patients were taken into account. Since the available data were extracted from small observational studies, no particular bias risk assessment was performed. Descriptive statistics were used to synthesize results.ResultsThere were 37 male (84.1%) and 6 female (13.6%) patients. The majority of patients (66%) were treated only by chest tube thoracostomy, which most of the times resulted in a complete resolution of the pneumothorax. Simple surveillance was applied in 10 cases. Three patients underwent minimally invasive surgery. In 14 cases (31.8%) air-filled lesions were detected on imaging. Eleven patients received corticosteroids during their hospital stay. In the majority of cases (86.3%) the pneumothorax was resolved.DiscussionEven if the level of evidence, derived from case reports and small case series is low, the existence of a true secondary spontaneous pneumothorax due to SARS-CoV-2 should be recognized. Imaging techniques should be repeated throughout the clinical course of the patients in order to detect newly developed pulmonary complications. Surgical treatment is feasible and patients whose general condition permits, should be offered surgery according to the existing guidelines regarding spontaneous pneumothorax. National registries and databases are necessary in order to better understand the pathogenesis and complications of this novel entity.

Project description:BACKGROUND:The aim of the current study was to evaluate the impact of the coronavirus disease (COVID-19) pandemic on musculoskeletal tumor service by conducting an online survey of physicians. METHODS:The survey was conducted among the members of the ISOLS (International Society of Limb Salvage) and the EMSOS (European Musculo-Skeletal Oncology Society). The survey consisted of 20 questions (single, multiple-response, ranked): origin and surgical experience of the participant (four questions), potential disruption of healthcare (12 questions), and influence of the COVID-19 pandemic on the particular physician (four questions). A matrix with four different response options was created for the particular surgical procedures). RESULTS:One hundred forty-nine physicians from five continents completed the survey. Of the respondents, 20.1% and 20.7% stated that surgery for life-threatening sarcomas were stopped or delayed, respectively. Even when the malignancy was expected to involve infiltration of a neurovascular bundle or fracture of a bone, still 13.8% and 14.7% of the respondents, respectively, stated that surgery was not performed. In cases of pending fractures of bone tumors, 37.5 to 46.2% of operations were canceled. CONCLUSION:The SARS-CoV-2 pandemic caused a significant reduction in healthcare (surgery, radiotherapy, chemotherapy) for malignancies of the musculoskeletal system. Delaying or stopping these treatments is life-threatening or can cause severe morbidity, pain, and loss of function. Although the coronavirus disease causes severe medical complications, serious collateral damage including death due to delayed or untreated sarcomas should be avoided.

Project description:Although autoantibodies are routinely screened in patients with idiopathic interstitial pneumonia, there are no reliable data on their clinical usefulness. The aim of this study was to investigate the prognostic value of autoantibodies for predicting the development of new connective tissue disease in these patients and also mortality. We conducted retrospective analysis of the baseline, and follow-up data for 688 patients with idiopathic interstitial pneumonia (526 with idiopathic pulmonary fibrosis, 85 with nonspecific interstitial pneumonia, and 77 with cryptogenic organizing pneumonia) at one single tertiary referral center. The median follow-up period was 33.6 months. Antinuclear antibody was positive in 34.5% of all subjects, rheumatoid factor in 13.2%, and other specific autoantibodies were positive between 0.7%-6.8% of the cases. No significant difference in patient survival was found between the autoantibody-positive and -negative groups. However, the presence of autoantibodies, especially antinuclear antibody with a titer higher than 1:320, was a significant predictor for the future development of new connective tissue diseases (relative risk, 6.4), although the incidence was low (3.8% of all subjects during follow-up). In conclusion, autoantibodies are significant predictors for new connective tissue disease development, although they have no prognostic value.

Project description:The aim of this study was to describe the high-resolution CT (HRCT) scan features that characterize familial interstitial pneumonia (FIP).FIP was defined by the presence of two or more cases of probable or definite idiopathic interstitial pneumonia (IIP) in individuals related within three degrees. The cases were collected consecutively from three centers. We identified 371 individuals with potential FIP from 289 families, including 340 individuals who had HRCT scans. Two chest radiologists independently reviewed the HRCT scans, scoring the extent and distribution of HRCT scan findings, and assessed the overall radiologic diagnosis.HRCT scan abnormalities suggestive of IIP were present in 85% (289 of 340 subjects). The most frequent findings were reticular pattern (n = 238, 82%) and ground-glass opacity (GGO) associated with reticular abnormality (n = 231, 80%). Other changes included GGO in 116 (40%), honeycombing in 92 (32%), and micronodules in 65 (22%). In the 289 cases with evidence of IIP, the findings were diffusely distributed in the craniocaudal plane in 186 (64%), and the lower lung zones were predominantly involved in 89 (31%). In the axial plane, 194 (67%) had a subpleural distribution; 88 (30%) were diffuse. The imaging pattern was classified as definite or probable usual interstitial pneumonia (UIP) in only 62 subjects (22%) and definite or probable nonspecific interstitial pneumonia (NSIP) in 35 subjects (12%). In 160 subjects (55%), the imaging findings did not conform to previously described UIP or NSIP patterns.Reticulation and a mixed GGO/reticular pattern are the most common HRCT scan findings in FIP. The parenchymal abnormalities are most often diffuse in the craniocaudal dimension and have a predominantly peripheral distribution in the axial dimension. Although a radiologic UIP pattern is not uncommon, most cases do not conform to typical UIP or NSIP patterns.

Project description:AimsTo explore the impact of the coronavirus disease lockdown on diabetes patients living in Jeddah, Saudi Arabia, in terms of their compliance with medication intake and lifestyle habits, and quality of life.MethodsIn this cross-sectional, qualitative prospective study, a questionnaire was administered over the telephone to diabetes patients who had attended National Guard primary care centers in Jeddah, Saudi Arabia. The survey included questions on demographic data, type of diabetes, medications used, comorbidities, medication compliance, and daily habits before and after the lockdown, and those assessing patients' psychological parameters during the past month by using the Kessler Psychological Distress Scale (K10). Data analysis was performed using SPSS program version 26.ResultsTotally, 394 patients participated. All of them had type 2 diabetes, and 37.6% had only one comorbidity. Antidiabetic monotherapy was used in 76.4% of the patients, while combination therapy was used in 23.6%. The compliance score before the lockdown was significantly higher (18.49 ± 3.05) than that after it (17.40 ± 3.25) (p-value <0.001). The average psychological assessment score was 9.78 ± 4.14 (range 8-35). Male participants and smokers had a significantly better psychological status than female participants (p-value = 0.002) and non-smokers (p value < 0.001), respectively.ConclusionsThe patients' levels of compliance with medications and healthy lifestyle habits were significantly reduced after the lockdown. These findings highlight the need for healthcare professionals to encourage diabetes patients to adhere to healthy lifestyle habits and use telemedicine during lockdowns to ensure optimal blood glucose control and reduce the incidence of complications.
