[PMID: 37623363 PMCID: PMC10455552 DOI: 10.3390/jcdd10080350] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 07/31/2023] [Accepted: 08/13/2023] [Indexed: 08/26/2023] Open
Abstract
Pulmonary hypertension (PH) was once a devastating and fatal disease entity, the outlook of which has been significantly improved by the continued progress of medical treatment algorithms. However, some patients still ultimately fail to achieve an adequate clinical response despite receiving maximal medical treatment. Historically, lung transplantation (LTx) has been the only effective therapeutic option that could lead to satisfactory outcomes and save these advanced patients' lives. However, patients with PH tend to have the highest mortality rates on the transplant waiting list; especially after comprehensive medical treatment, they continue to deteriorate very rapidly, eventually missing optimal transplantation windows. Balancing optimized medical treatment with the appropriate timing of referral and listing has been highly controversial in LTx for patients with PH. The 2021 consensus document for the selection of lung transplant candidates from the International Society for Heart and Lung Transplantation (ISHLT) updated the specific recommendations for the LTx referral and listing time for patients with PH based on objective risk stratification. Herein, we review the evolving PH-related concepts and highlight the optimization of LTx referral and listing for patients with PH, as well as their management on the waiting list.

Melatonin inhibits inflammasome-associated activation of endothelium and macrophages attenuating pulmonary arterial hypertension. Cardiovasc Res 2021; 116:2156-2169. [PMID: 31774487 DOI: 10.1093/cvr/cvz312] [Citation(s) in RCA: 31] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2019] [Revised: 09/25/2019] [Accepted: 11/25/2019] [Indexed: 01/08/2023] Open
Abstract
AIMS Pulmonary arterial hypertension (PAH) is a pathophysiological syndrome associated with pulmonary/systemic inflammation. Melatonin relieves PAH, but the molecular mode of action remains unclear. Here, we investigated the role of melatonin in normalizing vascular homeostasis. METHODS AND RESULTS Light-time mean serum melatonin concentration was lower in patients with PAH than in normal controls [11.06 ± 3.44 (7.13-15.6) vs. 14.55 ± 1.28 (8.0-19.4) pg/mL], which was negatively correlated with increased serum levels of interleukin-1β (IL-1β) in patients with PAH. We showed that inflammasomes were activated in the PAH mice model and that melatonin attenuated IL-1β secretion. On one hand, melatonin reduced the number of macrophages in lung by inhibiting the endothelial chemokines and adhesion factors. Moreover, use of Il1r-/- mice, Caspase1/11-/- mice, and melatonin-treated mice revealed that melatonin reduced hypoxia-induced vascular endothelial leakage in the lung. On the other hand, we verified that melatonin reduced the formation of inflammasome multiprotein complexes by modulating calcium ions in macrophages using a live cell station, and melatonin decreased inositol triphosphate and increased cAMP. Furthermore, knockdown of melatonin membrane receptors blocked melatonin function, and a melatonin membrane receptors agonist inactivated inflammasomes in macrophages. CONCLUSION Melatonin attenuated inflammasome-associated vascular disorders by directly improving endothelial leakage and decreasing the formation of inflammasome multiprotein complexes in macrophages. Taken together, our data provide a theoretical basis for applying melatonin clinically, and inflammasomes may be a possible target of PAH treatment.

Abstract
Sarcoidosis is a systemic inflammatory disease defined by the presence of aberrant granulomas affecting various organs. Due to its multisystem involvement, care of patients with established sarcoidosis becomes challenging, especially in the intensive care setting. While the lungs are typically involved, extrapulmonary manifestations also occur either concurrently or exclusively within a significant proportion of patients, complicating diagnostic and management decisions. The scope of this review is to focus on what considerations are necessary in the evaluation and management of patients with known sarcoidosis and their associated complications within a cardiopulmonary and critical care perspective.

Abstract
Pulmonary hypertension (PH) is the condition of elevated pressures in the pulmonary circulation. PH can develop acutely in patients with critical illness such as acute respiratory distress syndrome, sepsis, massive pulmonary embolism, left ventricular dysfunction, or after surgery. In a cancer patient, unique etiologies such as myeloproliferative disorders, tyrosine kinase inhibitors, or tumor emboli may result in PH. Early recognition and treatment of the causative condition may reverse acute PH or return chronic PH to its baseline status. Progression of the disease or its decompensation due to infection, a thromboembolic event, or other triggers can lead to admission to an intensive care unit. Regardless of etiology, the development or worsening of PH may precipitate hypoxemia, hemodynamic instability, or right ventricular failure, which can be challenging to manage or even fatal. In select cases, rapid institution of advanced treatment modalities may be warranted. This chapter reviews the etiology, epidemiology, pathophysiology, clinical features, diagnosis, and prognosis of PH and presents a comprehensive analysis of PH and right heart failure management strategies in the critical care setting. In particular, a unique perspective on oncologically relevant PH is provided.
