- Japanese Pulmonary Arterial Hypertension Patients Fare Better On PAH Drugs, according to Study
(Pulmonary Hypertension News)
Fifty-six patients at the National Hospital Organization Okayama Medical Center, diagnosed between 1998 and 2012, were selected as participants. The average age of diagnosis was 32 years, with a survival rate of 96% of the patients 5 years after diagnosis, and a 78% survival rate 10 years after diagnosis. The mean survival period from the time of diagnosis while undergoing PAH treatment was 14.9 years.
Among these treated patients, 93% received prostacyclin analogs, 68% endothelia receptor antagonists, and 52% phosphodiesterase type 5 inhibitors. Overall, 75% of the patients were treated with some form of combination therapy...

- The homozygous VHLD126N missense mutation is associated with dramatically elevated erythropoietin levels, consequent polycythemia, and early onset severe pulmonary hypertension.
Von Hippel-Lindau (VHL) protein is the principal negative regulator of hypoxia sensing mediated by transcription factors. Mutations in exon 3 of the VHL gene lead to Chuvash (VHLR200W ) and Croatian (VHLH191D ) polycythemias. Here, we describe an infant of Bangladesh ethnicity with a novel homozygous VHLD126N mutation with congenital polycythemia and dramatically elevated erythropoietin (EPO) levels, who developed severe fatal pulmonary hypertension. In contrast to Chuvash polycythemia, erythroid progenitors (BFU-Es) did not reveal a marked EPO hypersensitivity. Further, NF-E2 and RUNX1 transcripts that correlate with BFU-Es EPO hypersensitivity in polycythemic mutations were not elevated. Pediatr Blood Cancer © 2014 Wiley Periodicals, Inc.

- Docosatetraenoyl LPA is Elevated in Exhaled Breath Condensate in Idiopathic Pulmonary Fibrosis
Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal disease with no effective medical therapies. Recent research has focused on identifying the biological processes essential to the development and progression of fibrosis, and on the mediators driving these processes. Lysophosphatidic acid (LPA), a biologically active lysophospholipid, is one such mediator. LPA has been found to be elevated in bronchoalveolar lavage (BAL) fluid of IPF patients, and through interaction with its cell surface receptors, it has been shown to drive multiple biological processes implicated in the development of IPF. Accordingly, the first clinical trial of an LPA receptor antagonist in IPF has recently been initiated. In addition to being a therapeutic target, LPA also has potential to be a biomarker for IPF. There is increasing interest in exhaled breath condensate (EBC) analysis as a non-invasive method for biomarker detection in lung diseases, but to what extent LPA is present in EBC is not known.

- Use of age-adjusted D-dimer levels to exclude lung blood clots
Using a patient's age to raise the threshold for an abnormal result of a blood test used to assess patients with a suspected pulmonary embolism (blood clot in lungs) appeared to be safe and led to fewer healthy patients with the diagnosis, according to a study. "Future studies should assess the utility of the age-adjusted cutoff in clinical practice. Whether the age-adjusted cutoff can result in improved cost-effectiveness or quality of care remains to be demonstrated," the authors conclude.

- Implementing Lessons Learned From Previous Bronchial Biopsy Trials in a New Randomized Controlled COPD Biopsy Trial With Roflumilast
Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory disease mediated by an array of inflammatory cells and mediators, but above all, CD8+ T-lymphocytes, macrophages and neutrophils are important players in disease pathogenesis. Roflumilast, a first-in-class, potent and selective phosphodiesterase 4 (PDE4) inhibitor, reduces the rate of exacerbations in patients with a high risk of future exacerbations and has been shown to reduce inflammatory cells and mediators in induced sputum, a surrogate of airway inflammation. However, these anti-inflammatory effects are yet to be confirmed in another robust study directly assessing inflammatory markers in bronchial sub-mucosa.
- FDA: Celgene's Otezla OK for Psoriatic Arthritis
I'm posting this article from MedPage Today not only for psoriasis sufferers but PDE-4's are also approved for treatment of COPD (see article above). This one has shown to have less GI side-effects than Rofumilast. PDE-4's are also showing promise as a potentially safer alternative to current treatments for a multitude of autoimmune conditions and some research suggests that they might even be beneficial for PH. It's a drug to keep an eye on.

- Pulmonary Hypertension Therapies Could Improve, Thanks To New Yale Study
While there is still much to be learned about this rare and deadly disease, a new study published researchers at Yale School of Medicine on pulmonary hypertension has revealed valuable insights into cells and how they function in relation to the onset and progression of the disease.
The new study, which was published in the February 27th edition of Cell Reports, highlights the researchers’ efforts to learn more about the specific cellular mechanisms that occur behind the scenes in terms of the way that cells are organized in pulmonary arteries in patients who have pulmonary hypertension. It is this organization of cells that has been found to directly lead to patients being short of breath and fatigued
”For the first time, we understand which cells are responsible and the cellular processes underlying their recruitment,” and adding that, “We looked at the mechanism involved in how these cells migrate along blood vessels.”
The result of diseases such as pulmonary hypertension and other vascular disorders such as atherosclerosis is the development of excess smooth muscle accumulation in vascular structures in the lungs. Healthy lungs have patterns that are similar is design to that of tree branches, and the smallest blood vessels that branch out from these structures normally do not have a muscular coating. In the case of PH, however,even these small blood vessel branches become muscularized, which in turn leads to labored breathing.

- Pulmokine Awarded $1.5 Million Stage B VITA Contract to Advance Inhaled Kinase Inhibitors for Pulmonary Arterial Hypertension
Pulmokine announced it has been awarded a Stage B Vascular Interventions and Therapeutic Advances (VITA) contract from the National Heart, Lung, and Blood Institute (NHLBI), a division of the National Institutes of Health (NIH). Proceeds from the contract will be used to develop an inhaled PDGF receptor kinase inhibitor for the treatment of pulmonary arterial hypertension (PAH). The VITA contract will fund the performance of studies that will support an Investigational New Drug (IND) application to be submitted to the FDA. - See more at: http://www.globenewswire.com/news-release/2014/03/27/621975/10074308/en/Pulmokine-Awarded-1-5-Million-Stage-B-VITA-Contract-to-Advance-Inhaled-Kinase-Inhibitors-for-Pulmonary-Arterial-Hypertension.html#sthash.xIWUo0aX.dpuf
"Preclinical results of our novel, inhaled PDGF receptor inhibitor are quite compelling, showing a meaningful decrease in pulmonary pressures in animal models of PAH. Importantly, by interfering with the PDGF receptor pathway, our candidates have the potential to address an underlying cause of PAH, not merely to alleviate its symptoms," said Dr. Zisman, the CEO of Pulmokine. "The VITA contract will allow us to complete additional studies required to advance our lead candidate into Phase 1 clinical trials in patients with PAH." - See more at: http://www.globenewswire.com/news-release/2014/03/27/621975/10074308/en/Pulmokine-Awarded-1-5-Million-Stage-B-VITA-Contract-to-Advance-Inhaled-Kinase-Inhibitors-for-Pulmonary-Arterial-Hypertension.html#sthash.xIWUo0aX.dpuf

- Pulmonary arterial hypertension common among Sjogrens Syndrome patients
Sjögren’s Syndrome is a chronic condition of the immune system that causes mucous membranes and moisture-secreting glands to function improperly. Dry eyes and mouth are the most common symptoms of the condition but in some cases the disease can affect major organ function.
A recent study found that pulmonary arterial hypertension (high blood pressure in the arteries in the lungs) is more common among patients with Primary Sjögren’s Syndrome.
The researchers discovered that the patients with pulmonary arterial hypertension were female, younger and had had Primary Sjögren’s Syndrome for a shorter amount of time.

- FDA Clarifies Its Position on Revatio Use in Children
The FDA announced clarifications to its previous recommendation related to prescribing Revatio (sildenafil; Pfizer) for children with pulmonary arterial hypertension (PAH).
In August 2012, the Revatio drug label was revised with an added warning that stated “use of Revatio, particularly of chronic use, is not recommended in children.” This recommendation was based on data from a long-term clinical trial in pediatric patients that showed increasing mortality with increasing Revatio doses.
Although Revatio is approved only to treat PAH in adults, healthcare providers must consider whether the benefits of treatment are likely to outweigh the risks for each patient. The Agency noted that there may be circumstances in which the benefit-risk profile of Revatio may be acceptable in individual children, if other treatment options are limited.
The recommendation from August 2012 was not intended to suggest that Revatio should never be prescribed for pediatric use.

- Endothelin antagonism and uric acid levels in pulmonary arterial hypertension: Clinical associations.
Elevated serum uric acid is detected in pulmonary arterial hypertension (PAH) and is associated with poor patient outcomes. High serum uric acid is an independent risk factor for cardiovascular disease and renal impairment. We analyzed the effects of endothelin receptor antagonism on serum uric acid in PAH patients participating in the Sitaxentan to Relieve Impaired Exercise (STRIDE)-2/2X trial, and the impact of uric acid on 6-minute walk distance (6MWD), time to clinical worsening (TtCW) and survival.
Endothelin receptor antagonism reduces serum uric acid in PAH patients, and this reduction is associated with improved survival and longer TtCW. Further prospective studies are needed to investigate the pathogenic role of serum uric acid in PAH and its prognostic potential.

Paradigm shift signals the evolution of trial design from treatment effect on symptoms to one that reflects clinical outcomes. This evolution has occurred in other disease states, such as systemic hypertension, hyperlipidemia, and congestive heart failure. Given the substantial clinical and economic burden of PAH, the shift to outcomes-based end points will likely help payers in their evaluation of new PAH-specific therapies. Further, in light of healthcare reform and its emphasis on quality and costeffectiveness, the availability of clinical outcomes data is increasingly important.
