- Disfunção ventricular esquerda em pacientes com suspeita de hipertensão arterial pulmonar(2014) GAVILANES, Francisca; ALVES JR., Jose Leonidas; FERNANDES, Caio; PRADA, Luis Felipe Lopes; JARDIM, Carlos Viana Poyares; MORINAGA, Luciana Tamie Kato; DIAS, Bruno Arantes; HOETTE, Susana; SOUZA, RogerioObjective: To evaluate the role of right heart catheterization in the diagnosis of pulmonary arterial hypertension (PAH). Methods: We evaluated clinical, functional, and hemodynamic data from all patients who underwent right heart catheterization because of diagnostic suspicion of PAH-in the absence of severe left ventricular dysfunction (LVD), significant changes in pulmonary function tests, and ventilation/perfusion lung scintigraphy findings consistent with chronic pulmonary thromboembolism between 2008 and 2013 at our facility. Results: During the study period, 384 patients underwent diagnostic cardiac catheterization at our facility. Pulmonary hypertension (PH) was confirmed in 302 patients (78.6%). The mean age of those patients was 48.7 years. The patients without PH showed better hemodynamic profiles and lower levels of B-type natriuretic peptide. Nevertheless, 13.8% of the patients without PH were categorized as New York Heart Association functional class III or IV. Of the 218 patients who met the inclusion criteria, 40 (18.3% and 178 (81.7%) were diagnosed with PH associated with LVD (PH-LVD) and with PAH, respectively. The patients in the HP-LVD group were significantly older than were those in the PAH group (p < 0.0001). Conclusions: The proportional difference between the PAH and PH-LVD groups was quite significant, considering the absence of echocardiographic signs suggestive of severe LVD during the pre-catheterization investigation. Our results highlight the fundamental role of cardiac catheterization in the diagnosis of PAH, especially in older patients, in whom the prevalence of LVD that has gone undiagnosed by non-invasive tests is particularly relevant.
- Use of medical therapies before pulmonary endarterectomy in chronic thromboembolic pulmonary hypertension patients with severe hemodynamic impairment(2020) CASTRO, Marcela Araujo; PILOTO, Bruna; FERNANDES, Caio Julio Cesar dos Santos; JARDIM, Carlos; SALIBE FILHO, William; OLEAS, Francisca Gavilanes; ALVES, Jose Leonidas; MORINAGA, Luciana Tamie Kato; HOETTE, Susana; TERRA FILHO, Mario; FREITAS FILHO, Orival; JATENE, Fabio Biscegli; SOUZA, RogerioChronic thromboembolic pulmonary hypertension (CTEPH) is a rare complication of acute pulmonary embolism, characterized by non-resolving fibro-thrombotic obstructions of large pulmonary arteries. Pulmonary endarterectomy (PEA) is the treatment of choice for the disease, significantly improving survival. Patients with worse hemodynamic profile have worse prognosis after surgery, raising the question of whether the use of medical therapy prior to surgery to optimize hemodynamics could improve outcomes. The aim of this study was to evaluate the role of medical therapy pre-PEA, according to the hemodynamic profile at the diagnosis. We retrospectively analyzed all patients submitted to PEA, from January 2013 to December 2017. Functional, clinical and hemodynamic data were collected to evaluate the main prognostic determinants. Patients were stratified according to the hemodynamic severity and use of targeted therapies prior to surgery. A total of 108 patients were included. Thirty-five patients (32,4%) used targeted therapy pre-PEA. The use of medical therapy delayed the surgical procedure by about 7 months. There was no difference in overall survival between patients that received targeted therapy and those treated only with supportive therapy (87.8% vs 80.3%, respectively, p = 0.426). Nevertheless, when analyzing the group of patients with severe hemodynamic impairment, defined by low cardiac output(< 3.7L/min) at baseline, patients treated with targeted therapies presented a significantly better one-year survival. In higher-risk CTEPH patients, characterized by the presence of low cardiac output, the use of targeted therapies prior to PEA was associated with better outcome, suggesting a potential role for pre-operative use of medical treatment in this particular subgroup.
- Real-world evidence to advance knowledge in pulmonary hypertension: Status, challenges, and opportunities. A consensus statement from the Pulmonary Vascular Research Institute's Innovative Drug Development Initiative's Real-world Evidence Working Group(2023) MORLAND, Kellie; GERGES, Christian; ELWING, Jean; VISOVATTI, Scott H.; WEATHERALD, Jason; GILLMEYER, Kari R.; SAHAY, Sandeep; MATHAI, Stephen C.; BOUCLY, Athenais; WILLIAMS, Paul G.; HARIKRISHNAN, Sivadasanpillai; MINTY, Evan P.; HOBOHM, Lukas; JOSE, Arun; BADAGLIACCA, Roberto; LAU, Edmund M. T.; JING, Zhi-Cheng; VANDERPOOL, Rebecca R.; FAUVEL, Charles; ALVES, Jose Leonidas; STRANGE, Geoff; PULIDO, Tomas; QIAN, Junyan; LI, Mengtao; MERCURIO, Valentina; ZELT, Jason G. E.; MOLES, Victor M.; CIRULIS, Meghan M.; NIKKHO, Sylvia M.; BENZA, Raymond L.; ELLIOTT, C. GregoryThis manuscript on real-world evidence (RWE) in pulmonary hypertension (PH) incorporates the broad experience of members of the Pulmonary Vascular Research Institute's Innovative Drug Development Initiative Real-World Evidence Working Group. We aim to strengthen the research community's understanding of RWE in PH to facilitate clinical research advances and ultimately improve patient care. Herein, we review real-world data (RWD) sources, discuss challenges and opportunities when using RWD sources to study PH populations, and identify resources needed to support the generation of meaningful RWE for the global PH community.
- Pulmonary artery enlargement in schistosomiasis associated pulmonary arterial hypertension(2015) HOETTE, Susana; FIGUEIREDO, Claudia; DIAS, Bruno; ALVES- JR., Jose Leonidas; GAVILANES, Francisca; PRADA, Luis Felipe; JASINOWODOLINSKI, Dany; MORINAGA, Luciana Tamie Kato; JARDIM, Carlos; FERNANDES, Caio Julio Cesar; SOUZA, RogerioBackground: Schistosomiasis associated pulmonary arterial hypertension (Sch-PAH) might represent the most prevalent form of PAH worldwide. In Sch-PAH, the presence of aneurismal dilation of the pulmonary artery has been described, although it is still a matter of debate whether on average the pulmonary artery is more enlarged in Sc-PAH than IPAH. Methods: We retrospectively evaluated patients with IPAH (n = 25) and Sch-PAH (n = 22) who underwent computed tomography pulmonary angiogram and right heart catheterization. Results: Sch-PAH patients were older and presented less severe hemodynamic profiles. Main pulmonary artery diameter (MPAD) was greater in Sch-PAH than IPAH (4.5 +/- 1.8 vs 3.7 +/- 1.1 cm, p = 0.018). For the same level of mean pulmonary artery pressure, the MPAD in Sch-PAH was 0.89 cm larger than in IPAH (Covariance model p = 0.02). Conclusion: This study demonstrated that pulmonary artery enlargement is more pronounced in Sch-PAH than IPAH, independently of mean pulmonary artery pressure level, suggesting that this is more likely a feature of Sch-PAH.
- Loss of response to calcium channel blockers after long-term follow-up treatment in patients with idiopathic pulmonary arterial hypertension(2023) PILOTO, Bruna; FERNANDES, Caio Julio Cesar dos Santos; JARDIM, Carlos; CASTRO, Marcela; ALVES- JR., Jose Leonidas; SOUZA, RogerioIdiopathic pulmonary arterial hypertension (PAH) patients with a positive response to acute vasodilator challenge and a clinical response to calcium channel blockers (CCBs) for at least one year are traditionally designated true responders. Nevertheless, little is known about a sustained response to CCBs over longer periods of time. We evaluated the loss of response to CCBs after long-term treatment in a cohort of idiopathic PAH patients previously classified as being true responders. Our data suggest that idiopathic PAH patients can lose clinical response to CCBs even after one year of clinical stability, reinforcing the need for constant multidimensional reevaluation to assess the need for targeted PAH therapies and to classify these patients correctly.
- Validation of the North America expert consensus statement on reporting CT findings for COVID-19 in individuals with lung cancer(2022) PEIXOTO, D.; NEVES, Y. C. S.; GENEROSO, G.; LOUREIRO, B. M. C.; CALLIA, J. P. B.; ANASTACIO, V. M.; ALVES, J. L.; OSHIRO, E. M.; LIMA, L. R.; SAWAMURA, M. V. Y.; AUAD, R. V.; BITTENCOURT, M. S.; ABDALA, E.; IBRAHIM, K. Y.The aim of our study was to validate the use of the standardized Radiological Society of North America (RSNA) reporting system in individuals with known lung cancer who presented to the emergency department with suspected COVID-19. We included patients aged 18 years or older from the Cancer Institute of the State of Sao Paulo (ICESP) with a confirmed diagnosis of lung cancer, admitted to the emergency department and undergoing chest computed tomography (CT) for suspicion of COVID-19. Comparison between SARS-CoV2 RT-PCR across RSNA categories was performed in all patients and further stratified by diagnosis of lung cancer progression. Among 58 individuals included in the analysis (65 +/- 9 years, 43% men), 20 had positive RT-PCR. Less than a half (43%) had no new lung findings in the CT. Positive RT-PCR was present in 75% of those with typical findings according to RSNA and in only 9% when these findings were classified as atypical or negative (Po0.001). Diagnostic accuracy was even higher when stratified by the presence or absence of progressive disease (PD). Extent of pulmonary inflammatory changes was strongly associated with higher mortality, reaching a lethality of 83% in patients with >25% of lung involvement and 100% when there was >50% of lung involvement. The lung involvement score was also highly predictive of prognosis in this population as was reported for non-lung cancer individuals. Collectively, our results demonstrated that diagnostic and prognostic values of chest CT findings in COVID-19 are robust to the presence of lung abnormalities related to lung cancer.
- Clinical presentation and in-hospital prognosis of lung cancer patients presenting with suspected and confirmed COVID-19(2022) PEIXOTO, D.; CALLIA, J. P. B.; BITTENCOURT, M. S.; GENEROSO, G.; ANASTACIO, V. M.; ALVES-JR, J. L.; SILVA, T. L. da; BELIZARIO, J. C.; ARAUJO, B. L. M.; HO, W.; DIZ, M. D. P. E.; HOFF, P. M.; ABDALA, E.; IBRAHIM, K. Y.We sought to compare the clinical presentation and prognosis of patients with lung cancer and confirmed COVID-19 infection to those with negative RT-PCR SARS-CoV-2 results. We included patients with confirmed lung cancer and suspected COVID-19 who presented to the emergency department. The primary outcome was in-hospital mortality and secondary outcomes included admission to intensive care unit (ICU) or mechanical ventilation. We analyzed the characteristics according to RT-PCR results and primary outcome. We constructed a logistic regression for each RT-PCR result group to find potential predictors of the primary outcome. Among 110 individuals with confirmed lung cancer (65 +/- 9 years, 51% male), 38 patients had positive RT-PCR and 72 patients had negative RT-PCR. There was no difference between groups for any clinical characteristic or comorbidities though individuals with confirmed COVID-19 had higher functionality in the ECOG scale. Leucocytes and lymphocytes were lower in individuals with positive tests. The primary outcome occurred in 58 (53%) individuals, 37 (34%) were admitted to the ICU, and 29 (26%) required mechanical ventilation. Although mortality was similar between the two groups, individuals with confirmed COVID-19 were significantly more likely to be admitted to the ICU or receive mechanical ventilation. Only lower lymphocytes and higher CRP were significantly associated with higher mortality. The clinical presentation of COVID-19 in lung cancer is not sufficient to identify higher or lower probability groups among symptomatic individuals, the overall mortality is high irrespective of RT-PCR results, and lymphopenia on admission was associated with the diagnosis and prognosis for COVID-19.
- New anticoagulants for the treatment of venous thromboembolism(2016) FERNANDES, Caio Julio Cesar dos Santos; ALVES JUNIOR, Jose Leonidas; GAVILANES, Francisca; PRADA, Luis Felipe; MORINAGA, Luciana Kato; SOUZA, RogerioWorldwide, venous thromboembolism (VTE) is among the leading causes of death from cardiovascular disease, surpassed only by acute myocardial infarction and stroke. The spectrum of VTE presentations ranges, by degree of severity, from deep vein thrombosis to acute pulmonary thromboembolism. Treatment is based on full anticoagulation of the patients. For many decades, it has been known that anticoagulation directly affects the mortality associated with VTE. Until the beginning of this century, anticoagulant therapy was based on the use of unfractionated or low-molecular-weight heparin and vitamin K antagonists, warfarin in particular. Over the past decades, new classes of anticoagulants have been developed, such as factor Xa inhibitors and direct thrombin inhibitors, which significantly changed the therapeutic arsenal against VTE, due to their efficacy and safety when compared with the conventional treatment. The focus of this review was on evaluating the role of these new anticoagulants in this clinical context.
- Inhaled iloprost as third add-on therapy in idiopathic pulmonary arterial hypertension(2021) FERNANDES, Caio J. C. S.; SILVA, Taysa A. F. da; JR, Jose L. Alves; JARDIM, Carlos V. P.; SOUZA, Rogerio deTriple combination therapy is suggested in current pulmonary arterial hypertension guidelines in case of unsatisfactory treatment with oral double combination therapy. However, there is a lack of evidence concerning some of the drug combinations currently employed. We demonstrate the clinical and hemodynamical benefits of inhaled iloprost as third add-on therapy in idiopathic pulmonary arterial hypertension.
- Pulmonary Arterial Hypertension in the Southern Hemisphere Results From a Registry of Incident Brazilian Cases(2015) ALVES JR., Jose Leonidas; GAVILANES, Francisca; JARDIM, Carlos; FERNANDES, Caio Julio Cesar dos Santos; MORINAGA, Luciana Tamie Kato; DIAS, Bruno; HOETTE, Susana; HUMBERT, Marc; SOUZA, RogerioBACKGROUND: Pulmonary arterial hypertension (PAH) is a rare and ultimately fatal disorder of the pulmonary vasculature. There is increasing interest in the worldwide characteristics of patients with PAH, although data coming from the Southern Hemisphere remain scarce. The objective of this study was to describe a cohort of incident patients with PAH from a large reference center in Brazil. METHODS: All consecutive patients who received a diagnosis of PAH by right-sided heart catheterization between 2008 and 2013 were included in the study. RESULTS: A total of 178 patients with newly diagnosed PAH were enrolled in the study (mean age, 46 years; female/male ratio, 3.3: 1; 45.5% in New York Heart Association functional class III or IV). Idiopathic PAH (IPAH), connective tissue disease (CTD), and schistosomiasis-associated PAH (Sch-PAH) accounted for 28.7%, 25.8%, and 19.7% of all cases, respectively. The patients were treated with phosphodiesterase type 5 inhibitors (66%), endothelin receptor antagonists (27%), or a combination of both (5%). For the PAH group as a whole, the estimated survival rate 3 years aft er diagnosis was 73.9%. The prognosis for the patients with CTD was worse than that for the patients with IPAH and Sch-PAH (P = .03). CONCLUSIONS: The distribution of PAH causes and the baseline characteristics in our registry clearly differ from the previously published European and US-based registries. These differences highlight the importance of regional registries and also raise questions regarding the need to better account for such differences in future clinical trials.
