  • Treating Inflammation in PAH Using Antioxidant Inflammation Modulators
  • (Pulmonary Hypertension News) With the eminent clinical need for a new PAH therapy, an extensive body of leading academic scientists has been developing cutting edge investigations for production of novel drugs. Among those developing therapies for the disease, Reata Pharmaceuticals, Inc. is developing a novel class of drugs with potent transcriptional activity called antioxidant inflammation modulators (AIMs). The company has already focused early research collaborations involving the therapeutic use of AIMs in treating several diseases such as melanoma, lung cancer, Freidreich’s Ataxia, Mitochondrial Myopathies, and Radiation Dermatitis, as well as for RTA402 (also known an bardoxolone methyl), an AIM being tested and developed  as a potential therapy for treating the underlying inflammation in PAH.

    But one appendage of PANTHER-IPF was allowed to live on: the 81 patients taking N-acetylcysteine (which seemed safe enough), and their placebo-taking controls. Those results were announced at the American Thoracic Society 2014 meeting, and published in the New England Journal in May 2014:

    N-acetylcysteine showed no benefit over placebo in the treatment of idiopathic pulmonary fibrosis.
    ....
    The same national meeting and journal issue announced the exciting success of pirfenidone and nintedanib for slowing lung function decline in IPF, and possibly even preventing IPF exacerbations and extending life for people with idiopathic pulmonary fibrosis.

  • Sarcoidosis-Associated Pulmonary Hypertension and Lung Transplantation for Sarcoidosis
  • (MedScape) Abstract

    Pulmonary hypertension (PH) is a significant complication of sarcoidosis, occurring in approximately 6 to > 20% of cases, and markedly increases mortality among these patients. The clinician should exercise a high index of suspicion for sarcoidosis-associated PH (SAPH) given the nonspecific symptomatology and the limitations of echocardiography in this patient population. The pathophysiology of PH in sarcoidosis is complex and multifactorial. Importantly, there are inherent differences in the pathogenesis of SAPH compared with idiopathic pulmonary arterial hypertension, making the optimal management of SAPH controversial. In this article, we review the epidemiology, diagnosis, prognosis, and treatment considerations for SAPH. Lung transplantation (LT) is a viable therapeutic option for sarcoid patients with severe pulmonary fibrocystic sarcoidosis or SAPH refractory to...

  • Local and Systemic RAGE Axis Changes in Pulmonary Hypertension: CTEPH and iPAH
  • (Plos One) The molecular determinants of chronic thromboembolic pulmonary hypertension (CTEPH) and idiopathic pulmonary arterial hypertension (iPAH) remain poorly understood. The receptor for advanced glycation endproducts (RAGE) and its ligands: HMGB1 and S100A9 are involved in inflammatory disorders. We sought to investigate the role of the RAGE axis in patients with CTEPH undergoing pulmonary endarterectomy (PEA), iPAH undergoing lung transplantation (LuTX). The high pulmonary vascular resistance in CTEPH/iPAH results in pressure overload of the right ventricle. We compared sRAGE measurements to that of patients with aortic valve stenosis (AVS) – pressure overload of the left ventricle.

  •  Information experiences and needs in patients with pulmonary arterial hypertension or chronic thromboembolic pulmonary hypertension.
  • (Nursing Research and Practice) Background. Pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) are fatal, noncurable, but treatable diseases that strongly affect the patients. Objective. To describe patients' experience of information relating to PAH or CTEPH. Methods. A qualitative method using content analysis was applied.
    [..]
    Conclusions. In the future, healthcare organizations must struggle to achieve a holistic healthcare by making it more person-centred, and they must also promote cooperation between PAH centres and local healthcare providers. It is essential to determine the most appropriate and valuable path of information and communication and, thereby, the most cost-effective management of PAH or CTEPH.

  • Bosentan Makes No Impact on PH Associated With Fibrotic IIP
  • (Practical Reviews) PH is a commonly encountered problem in patients with advanced IIP and carries a significantly worse prognosis. Current expert consensus discourages use of PH-specific therapy for these patients. This randomized placebo-controlled trial of patients with PH and fibrotic IIP showed no benefit of treatment with bosentan. PVRi was chosen as the primary end point for the trial and, although PVRi is a strong predictor of mortality, it is not known whether a change in PVRi is associated with outcomes nor what a clinically significant change is. Another important consideration is the short duration of the trial. Perhaps longer trials are needed to demonstrate disease stability and/or improvement in hemodynamics in this patient population. At this point, bosentan should not be used to treat PH associated with fibrotic IIP.(Reviewer–Nadine Al-Naamani, MD).

  • United Therapeutics Blocks Generic PAH Drug For Remodulin in Patent Case
  • (Pulmonary Hypertension News) First approved in the United States in May 2002, Remodulin is a prostacyclin vasodilator used for the treatment of pulmonary arterial hypertension. The therapy is typically used to decrease symptoms associated with exercise. In patients with PAH, Remodulin is indicated to diminish the rate of clinical deterioration. Since it is considered a specialty medication for a rare, orphan disease, a 20 ml dose of Remodulin may cost over $6,000. The high price point of the drug has therefore made it an attractive target for generic drug manufacturers, who would like to produce a generic form of Remodulin and undercut United Therapeutics’ leading name-brand version of the drug — a gambit that Sandoz recently attempted, and that UT moved to block in the courts.
