Since the beginning of the SARS-CoV-2 outbreak, few cases of COVID-19 pneumonia in patients with pulmonary arterial hypertension have been reported. We present four patients with known history of PAH admitted to our hospital with SARS-CoV-2 pneumonia to analyze the impact of this disease on their clinical outcome.

The Impact

Pulmonary arterial hypertension is a progressive disease that can lead to right-sided ventricular failure and premature death. Tailoring therapy to individual patient’s needs, along with regular risk assessment, is integral for optimal outcomes in patients with pulmonary arterial hypertension. Results from the AMBITION trial support the use of upfront combination of tadalafil and ambrisentan. In a recent analysis of risk assessment in pulmonary arterial hypertension, abridged versions of the REVEAL 2.0 risk score were shown to be comparable to the full tools. In this report, we present a case series of the use of riociguat in upfront combination or sequentially, and the impact on risk scores as determined by the abridged REVEAL Lite 2.0 approach.

The Impact

Pulmonary hypertension (PH) is a condition characterised by an abnormal elevation of pulmonary artery pressure caused by an increased pulmonary vascular resistance, frequently leading to right ventricular failure and reduced survival. Marked sexual dimorphism is observed in patients with pulmonary arterial hypertension, a form of pulmonary hypertension with a particularly severe clinical course. The incidence in females is 2–4 times greater than in males, although the disease is less severe in females. We review the contribution of the sex chromosomes to this sex dimorphism highlighting the impact of proteins, microRNAs and long non-coding RNAs encoded on the X and Y chromosomes. These genes are centrally involved in the cellular pathways that cause increased pulmonary vascular resistance including the production of reactive oxygen species, altered metabolism, apoptosis, inflammation, vasoconstriction and vascular remodelling. The interaction with genetic mutations on autosomal genes that cause heritable pulmonary arterial hypertension such as bone morphogenetic protein 2 (BMPR2) are examined. The mechanisms that can lead to differences in the expression of genes located on the X chromosomes between females and males are also reviewed. A better understanding of the mechanisms of sex dimorphism in this disease will contribute to the development of more effective therapies for both women and men.

Abstract Background There are significant risks of parenteral prostacyclin use in patients with pulmonary arterial hypertension associated with congenital heart disease (PAH-CHD), which may limit their use. Selexipag is an oral, selective prostacyclin analogue that has been shown to reduce disease progression and improve exercise capacity in patients with PAH-CHD. Administering Selexipag in patients with PAH-CHD could potentially overcome some of the risks of parenteral therapy while improving clinical outcomes. Case summary We report five cases highlighting the clinical uses of Selexipag in patients with PAH-CHD. In the first two cases, Selexipag was initiated as part of a Treat-to-close strategy. In the third case, initiation of Selexipag improved symptoms and objective exercise capacity in a patient with Eisenmenger syndrome. In the fourth and fifth cases, rapid cross-titration protocols were used to transition from parenteral prostacyclins to Selexipag. In the fourth case, Selexipag was initiated in the context of significant side effects limiting parenteral prostacyclin use. In the fifth case, Selexipag was used to down-titrate from parenteral prostacyclins following closure of a sinus venosus atrial septal defect and redirection of anomalous pulmonary veins. Discussion Selexipag is a promising oral therapy for patients with at various stages of the spectrum of PAH-CHD to improve symptoms, exercise capacity and, in some cases, haemodynamics. Our cases also highlight practical aspects of Selexipag use including targeting the individualized maximally tolerated dose for each patient, managing side effects and managing dose interruptions.

Abstract Background Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare form of pulmonary hypertension caused by blood clots and scar tissue in the blood vessels of the lungs. Health-related quality of life is often significantly impaired in patients with CTEPH. However, a better understanding of how CTEPH symptoms affect patients’ lives is needed to optimally assess the impact of the disease and treatment. Objectives This qualitative study aimed to better understand the symptoms of CTEPH and how they affect patients’ lives, as well as to determine the appropriateness of the Pulmonary Arterial Hypertension – Symptoms and Impact (PAH-SYMPACT™) questionnaire for use in this patient population. Methods Adults diagnosed with CTEPH, recruited from two clinical sites in the US, participated in one-to-one qualitative telephone interviews. They described their experience of CTEPH symptoms and the impact these symptoms have on their lives. They also provided feedback on the comprehensibility and relevance of the PAH-SYMPACT™‘s instructions, items, and response options. Results Participants (N = 12) had a mean age of 62.5 years. Two thirds were female and most (83%) had undergone pulmonary endarterectomy and/or balloon pulmonary angioplasty. The most frequently endorsed symptoms were shortness of breath (endorsed by all 12 participants), fatigue (11 participants), and lightheadedness (10 participants). All participants identified shortness of breath as an “extremely important” symptom, and seven participants rated fatigue as “extremely important.” The most frequent impacts of CTEPH were on ability to walk quickly (endorsed by all 12 participants), ability to walk up inclines or stairs (11 participants), and ability to carry things (11 participants). The PAH-SYMPACT™ items were relevant to most participants and reflected their experience of CTEPH. All participants indicated that no important CTEPH symptoms were missing from the PAH-SYMPACT™. Overall, the instructions, items, and response options of the PAH-SYMPACT™ were clear and easy to understand. Conclusions The symptoms and impacts experienced by patients with CTEPH align with items included in the PAH-SYMPACT™. The PAH-SYMPACT™ appears to be fit for purpose for assessing disease status in patients with CTEPH.

There is limited data regarding the feasibility of transitioning from intravenous prostacyclins to selexipag in pulmonary arterial hypertension (PAH) patients. We present a case series of successful transitions from intravenous prostacyclins to selexipag in the majority of carefully selected five stable PAH patients using a standardized protocol in the outpatient setting.

Patients with pulmonary arterial hypertension associated with connective tissue disease (PAH-PAH-CTD) such as systemic sclerosis (SSc) have a poorer response to treatment and increased mortality compared with patients with idiopathic PAH. Current treatment options for PAH-CTD include prostanoids, phosphodiesterase type-5 inhibitors (PDE-5i), endothelin receptor antagonists, and the soluble guanylate cyclase stimulator riociguat. In this case series, we describe three patients with PAH-CTD related to limited scleroderma who were switched from a PDE-5i to riociguat due to insufficient clinical response. The switch to riociguat was associated with an improvement in respiratory and hemodynamic parameters and a favorable tolerability profile. These cases demonstrate that switching to riociguat is a therapeutic option in patients with PAH-CTD who have not achieved a satisfactory clinical response to a PDE-5i.

The Impact

Pulmonary arterial hypertension (PAH) is a fatal lung disease characterised by progressive remodelling of the small pulmonary vessels. The daily-life activities of patients with PAH are severely limited by exertional fatigue and dyspnoea. Typically, these symptoms have been explained by right heart failure. However, an increasing number of studies reveal that the impact of the PAH reaches further than the pulmonary circulation. Striated muscles other than the right ventricle are affected in PAH, such as the left ventricle, the diaphragm and peripheral skeletal muscles. Alterations in these striated muscles are associated with exercise intolerance and reduced quality of life. In this Back to Basics article on striated muscle function in PAH, we provide insight into the pathophysiological mechanisms causing muscle dysfunction in PAH and discuss potential new therapeutic strategies to restore muscle dysfunction.
