Pulmonary vasodilators in patients with advanced chronic kidney disease and pre-capillary pulmonary hypertension-A case series.

Pulmonary hypertension (PH) is a prevalent complication among patients with chronic kidney disease (CKD). In these patients, pulmonary vasodilators may be useful but are underused. We describe a group of patients with precapillary PH and advanced CKD treated with pulmonary vasodilators.

Shark fin sign: A rare EKG finding in a patient with Takotsubo cardiomyopathy from influenza A infection.

This case demonstrated the rare "shark fin" ECG pattern, an ST-segment elevation typically seen in acute myocardial infarction. We reported a case of takotsubo cardiomyopathy secondary to influenza A infection with multiple organ failure, showing the shark fin sign and resulting in in-patient mortality and various complication.

Clinical Characteristics and Outcomes Associated With Distinct Hemodynamic Patterns in End-stage Liver Disease: A Retrospective Cohort Analysis.

Introduction: Despite advances in the diagnosis and therapeutics strategies for pulmonary hypertension (PH) in patients with end-stage liver disease (ESLD), the impact of hemodynamic patterns among ESLD patients identified through right heart catheterization (RHC) on clinical outcomes remains poorly understood.

Methods: This single-center retrospective cohort study identified patients diagnosed with ESLD who underwent RHC from August 2018 to June 2023. Demographic and clinical data, including comorbidities, transthoracic echocardiography, and RHC findings, were obtained.

Association of mildly elevated pulmonary vascular resistance with major cardiovascular events in pulmonary hypertension and chronic kidney disease: A retrospective cohort analysis.

Pulmonary hypertension (PH) is associated with adverse outcomes in chronic kidney disease (CKD) patients. Our study suggests mildly elevated pulmonary vascular resistance ( > 2 to ≤ 3) is independently associated with major adverse cardiovascular events at 1-year follow-up. Early diagnosis of precapillary PH in CKD patients can potentially improve clinical outcomes.

Focal Alveolar Hemorrhage Secondary to Hydralazine-Associated Antineutrophilic Cytoplasmic Antibody Vasculitis.

Hydralazine is rarely associated with antineutrophilic cytoplasmic antibody (ANCA) vasculitis. In the appropriate clinical scenario, such as in a patient with pulmonary, renal, or cutaneous manifestations, finding antibodies against nuclear and cytoplasmic neutrophil antigens may suggest drug-induced vasculitis after exposure to hydralazine. We present the case of an elderly man diagnosed with focal alveolar hemorrhage with elevated concentrations of anti-myeloperoxidase antibody, anti-proteinase-3 antibody, and antinuclear antibodies in the setting of prolonged hydralazine therapy.

Clinical features and risk factors of adverse clinical outcomes in central pulmonary embolism using machine learning analysis.

Background: In prior studies, central pulmonary embolism (PE) was associated with high clot burden and was considered an independent predictor for thrombolysis. Further information about predictors of adverse outcomes in these patients is needed for better risk stratification. The objective is to describe independent predictors of adverse clinical outcomes in patients with central PE.

Clinical characteristics and treatment of patients with central pulmonary embolism and right heart thrombus.

Introduction: Right heart thrombus (RHT), also known as clot in transit, is an uncommon finding in pulmonary embolism (PE) that is associated with increased inpatient mortality. To date, there is no consensus on the management of RHT. Therefore, we aim to describe the clinical features, treatments, and outcomes of patients with simultaneous RHT and PE.

Coronavirus disease-19 infection and angioedema in African Americans: A case series.

Rationale: Few case series have described the simultaneous development of angioedema in patients with coronavirus 19 disease (COVID-19). Most of these reports were described in at-risk patients for developing bradykinin angioedema. Therefore, we aim to describe 5 African American patients who developed simultaneous COVID-19 and angioedema.

Risk factors associated with intubation and readmissions in patients with angioedema: A single-center experience al. / Ann Allergy Asthma Immunol 127 (2021) xxx-xxx"?>.

Background: Given the heterogeneity of etiologies, pathophysiology, and presentation of angioedema, variations in clinical outcomes, such as intubation and hospital readmissions, need further clarification.

Objective: To determine the factors associated with intubation and hospital readmissions in patients with angioedema.

Methods: Retrospective study of patients evaluated with a diagnosis of angioedema in a 6-year period.

Psychological impact of genetic and clinical screening for pulmonary fibrosis on asymptomatic first-degree relatives of affected individuals.

Screening for pulmonary fibrosis may help to identify early stages of the disease. We assessed the psychological impact of screening undiagnosed first-degree relatives of patients with pulmonary fibrosis by administering two validated measures after participants received their results: the Decisional Regret Scale and the Feelings About genomiC Testing Results Questionnaire. More than 90% of relatives reported either no or mild decisional regret.

A Tale of Two Proteolytic Machines: Matrix Metalloproteinases and the Ubiquitin-Proteasome System in Pulmonary Fibrosis.

Pulmonary fibrosis is a chronic and progressive lung disease characterized by the activation of fibroblasts and the irreversible deposition of connective tissue matrices that leads to altered pulmonary architecture and physiology. Multiple factors have been implicated in the pathogenesis of lung fibrosis, including genetic and environmental factors that cause abnormal activation of alveolar epithelial cells, leading to the development of complex profibrotic cascade activation and extracellular matrix (ECM) deposition. One class of proteinases that is thought to be important in the regulation of the ECM are the matrix metalloproteinases (MMPs).

Interstitial Lung Disease in Relatives of Patients with Pulmonary Fibrosis.

Although relatives of patients with familial pulmonary fibrosis (FPF) are at an increased risk for interstitial lung disease (ILD), the risk among relatives of sporadic idiopathic pulmonary fibrosis (IPF) is not known. To identify the prevalence of interstitial lung abnormalities (ILA) and ILD among relatives of patients with FPF and sporadic IPF. Undiagnosed first-degree relatives of patients with pulmonary fibrosis (PF) consented to participate in a screening study that included the completion of questionnaires, pulmonary function testing, chest computed tomography, a blood sample collection for immunophenotyping, telomere length assessments, and genetic testing.
