Discovery of Genetic Mutations that Cause PCH
2/11/2014

A team of researchers, led by physicians and scientists at Intermountain Healthcare's Intermountain Medical Center and ARUP Laboratories, has made a medical breakthrough by discovering genetic mutations that cause a rare and deadly lung disease.

The disease, pulmonary capillary hemangiomatosis or PCH, is a rare cause of pulmonary hypertension, which occurs predominantly in young adults. PCH affects less than one in a million people, and has been extremely difficult and expensive to diagnose, as well as challenging to treat. Read PHA's full release

Chest Radiography Highly Predictive of Pulmonary Hypertension
2/9/2014

(news-medical.net) - Chest radiography is very accurate for predicting pulmonary hypertension (PH), report researchers. “We felt inappropriate to rule in a radiologic diagnosis of PH only on the basis of a prominent main pulmonary artery,” the researchers write in Thrombosis Research. For this reason, they required the presence of at least one additional finding for a PH diagnosis: isolated enlargement of the right ventricle; a right descending pulmonary artery diameter greater than 16 mm; or pruning of peripheral pulmonary vessels. “By adopting these criteria, chest radiography yielded high diagnostic accuracy for PH,” they report.

Another Piece of the Pulmonary Hypertension Puzzle gets Plugged into Place
1/22/2014

(Stanford Medicine Scope Blog) - Pulmonary hypertension, a dangerous increase in the pressure of blood vessels in the lung, is one nasty disease, as I wrote in a Stanford Medicine article a few years ago. As many as three times as many women – many of them quite young – as men are diagnosed with the spontaneous form of PH (which can also arise from scleroderma or bad pharmaceuticals).

But recent work has strongly implicated inflammation in pushing predisposed tissues over the edge into the diseased state. And this week, a Journal of Experimental Medicine study led by PH specialist Marlene Rabinovitch, MD, and her colleagues at Stanford’s PH-focused Vera Moulton Wall Center plunks a potentially pivotal piece of the puzzle into place. Rabinovitch and her associates showed that levels of a pro-inflammatory growth factor usually designated by the acronym GM-CSF (if you really must know, it’s “granulocyte-macrophage colony stimulating factor”) rise substantially when a cell-surface receptor with a heavyweight acronym of its own, BMPR2 (for “bone morphogenic protein receptor”) isn’t functioning properly. That can be due to mutations in the gene that codes for the receptor (as occurs in familial versions of PH), to various environmental causes, or the interaction of the two. Read article

New Research May Boost Drug Efficacy
1/17/2014

(From MedicalXpress.com) - The development of new, more effective vasodilators to treat pulmonary arterial hypertension (PAH) has been hampered because of their systemic toxicity and adverse side effects. An international team of investigators seeking to surmount these problems and increase drug efficacy have determined that a vascular homing peptide can selectively target hypertensive pulmonary arteries to boost the pulmonary but not systemic effects of vasodilators. Importantly for potential clinical use, this peptide retains its activity when given sublingually. The results using a rat model of PAH are published in the American Journal of Pathology.

New Pulmonary Hypertension Drug Approved!
12/22/2013

Friday, the U.S. Food and Drug Administration (FDA) approved United Therapeutics' oral treprostinil, an extended-release tablet commercially known as Orenitram, for the treatment of pulmonary arterial hypertension (PAH). Orenitram is the first orally administered prostacyclin analogue approved by the FDA for any disease.

"PHA is always pleased as new treatments become available. They increase options for patient treatment, both individually and in combination with others," says PHA President Rino Aldrighetti. "This is the twelfth treatment for PAH, the third new therapy to be FDA approved in the last two months. During the past 10 years, the average number of drugs approved per year for all rare diseases is fewer than thirty. To have this kind of advancement for PAH is extraordinary and speaks to the medical and research structure that has been built in this field."

Most Effective Use of Treatments Requires Early Diagnosis

While huge strides have been made in the advancement of therapeutic options, the time it takes to reach a correct PH diagnosis has not changed over the last 20 years. Many patients will see three or more different physicians over a three year period before they are properly diagnosed with PH, and almost three-fourths have advanced PH by the time they are diagnosed.

“Misdiagnosis and delayed diagnosis have an impact on patient survival and quality of life,” explains PHA Senior Director of Volunteer Services Debbie Castro. "Because PHA sees early diagnosis as a huge priority, we are working with medical professionals and patients to improve diagnosis through our early diagnosis campaign, Sometimes it’s PH."

More Needs to be Done for Children

While there are 12 treatments for pulmonary arterial hypertension (PAH), none are specifically approved for pediatric patients. PHA has launched the only pediatric PH research program in the United States, the Robyn Barst Pediatric Research and Mentoring Fund.

And, says Rino, “Ultimately, our goal is a cure. With increasing numbers of researchers engaged in more studies every year, we are hopeful and encouraged as we see that hope turning into action.”

New Mitochondrial Research Promising for PH
12/17/2013

(Medical Xpress) Queen's University [in Canada] professor Stephen Archer's research has revealed that in serious human diseases (such as pulmonary hypertension, lung cancer, cardiac arrest and neurologic disease) the cell's power source, known as mitochondria, displays an abnormal structure.

Dr. Archer discussed his findings in a recent New England Journal of Medicine article.

"This explosion in the understanding of the once secret lives of mitochondria will almost certainly advance our understanding of an important mechanism for cell death and cell growth," says Dr. Archer. "This basic understanding offers new molecular targets for therapies of neurologic diseases, cancer and pulmonary hypertension." Read the full article

They are the first changes in the criteria since 1980. Read article

Eleventh PH Drug Approved, The Second in Just Ten Days
10/18/2013

Today the U.S. Food and Drug Administration (FDA) approved the eleventh pulmonary arterial hypertension (PAH) treatment in the U.S., Actelion Pharmaceutical’s macitentan (commercially known as Opsumit), an oral dual endothelin-receptor antagonist. This comes just ten days after the approval of riociguat (commercially known as Adempas) for the treatment of PAH and some cases of chronic thromboembolic pulmonary hypertension (CTEPH). These two new drugs are the first in five years to be approved by FDA for treating PH.

According to Healio, the phase 3 SERAPHIN drug trial for macitentan was the first to test a PAH drug for its effects on morbidity and mortality. Patients who took the drug showed lower rates of morbidity and mortality as compared to patients who received a placebo, showed improved six-minute walk tests and more showed improvement in their WHO functional class.

Acknowledging the achievement of adding an eleventh drug to the choices for PAH patients in a rare disease state, PHA President Rino Aldrighetti said, “Of the 7,000 rare diseases, only three have as many or more treatments available. We are fortunate to have a strong and growing research community with great communication and cooperation. That has helped foster industry interest in exploring new options for patients.”

PHA itself has committed more than $12.5 million to support cutting-edge research focused on pulmonary hypertension. PHA has been able to leverage such substantial funding through partnerships with the National Heart, Lung, and Blood Institute (NHLBI), American Thoracic Society (ATS), American Heart Association (AHA), and Pfizer.

We know that your ultimate wish is for a cure, and that is why PHA will continue to support the work of researchers until the day when no one suffers from PH.

New Drug Approved for PAH and CTEPH Patients in U.S.
10/10/2013

On Tuesday, the U.S. Food and Drug Administration (FDA) approved Bayer’s riociguat pill for the treatment of pulmonary arterial hypertension (PAH) and for chronic thromboembolic pulmonary hypertension (CTEPH).  Riociguat, commercially known as Adempas, will be used for CTEPH patients after pulmonary thromboendarterectomy (PTE) surgery or if surgery is not possible. This will be the first drug available for CTEPH patients and tenth for PAH.

PHA President Rino Aldrighetti says, “Treatment opportunities for patients are growing rapidly. Eighteen years ago there were no treatments for pulmonary arterial hypertension. Twelve years ago there was one. Today there are ten, with a possible eleventh later this year (Actelion’s macitentan). Of the 7,000 rare diseases, only three have as many or more treatments available. We are fortunate to have a strong and growing research community with great communication and cooperation. That has helped foster industry interest in exploring new options for patients.”

Better Prognosis for PH Patients

The strong progress in the field of pulmonary hypertension over the past two decades has led to a better prognosis for PH patients. Whereas physicians treating PH once delivered terminal diagnoses, they now expect their patients to live with their condition. Many patients survive for years -- even 10-20 years or more -- with proper PH treatment.

Patients Not Receiving Treatments in a Timely Manner

“The problem we now face is getting these treatments to patients sooner. While we have made huge strides over the past 20 years, the time it takes to reach a correct PH diagnosis has not changed,” explains PHA Vice President for Community Engagement Mollie Katz. “With missed or late diagnosis, the disease continues to get worse, affecting patients’ survival and quality of life. Many patients will see three or more different physicians over a three year period before they are properly diagnosed with PH, and almost three-fourths have advanced PH by the time they are diagnosed. Because PHA sees early diagnosis as a huge priority, second only to a cure, we are working with medical professionals and patients to improve diagnosis through our early diagnosis campaign, Sometimes it’s PH. 

Not There Yet

While there are 10 treatments for pulmonary arterial hypertension (PAH) and now one for CTEPH, there are none approved for pediatric patients. PHA has launched the only pediatric PH research program in the United States, the Robyn Barst Pediatric Research and Mentoring Fund.

And, says Rino, “Ultimately, our goal is a cure. With increasing numbers of researchers engaged in more studies every year, we are hopeful and encouraged as we see that hope turning into action.”

Blocking Molecular Pathway Reverses Pulmonary Hypertension in Rats
9/9/2013

A new study from researchers at the Stanford University School of Medicine published recently in Science Translational Medicine suggests that pulmonary hypertension may be caused by an inflammation-producing molecular pathway that damages the inner lining of blood vessels. The results suggest that medications to block this pathway could lead to a possible cure for pulmonary hypertension as well as a better understanding of other diseases involving inflammation of blood vessels, such as coronary artery disease.

Details of Updated UK Heart Failure Guidelines Raise Some Eyebrows
8/23/2011

8/17/11 (Forbes) - Much of the controversy revolves around the relative weight given to echocardiography and natriuretic peptides in the diagnosis and treatment of heart failure. The updated NICE guidelines recommend that for the diagnosis of heart failure in patients with no history of MI, echocardiography should be used only if natriuretic peptides are raised. Peterson and Rumsfeld point out that both the ESC and ACC/AHA guidelines recommend that all patients with the signs and symptoms of heart failure should have an echocardiogram. The NICE position, they say, “may be questioned because of the utility of echocardiography for not only measuring left ventricular function but also for detecting structural or valvular heart disease, pulmonary hypertension, and pericardial effusion.” Read article

Conference Research Room Helps Researchers Develop New Tests for PH Patients
8/12/2011

Georg Hansmann, MD, PhDAn interdisciplinary group of researchers from Boston have developed a microfluidic device that can test for the number of beneficial circulating endothelial progenitor cells (EPCs) in the blood stream of patients with cardiovascular disease. The number of EPCs in the blood can be used as a biomarker for risk assessment, disease progression and the response to therapy.  Up to now, the measurement of EPCs in the bloodstream was very difficult and laborious and therefore, not very useful to physicians working with PH Patients at the bedside.

Dr. Hansmann and colleagues have attended the research room at PHA’s 2010 International Conference to apply the so called "EPC Capture Chip"  in over 40 patients with PAH. They found the EPC numbers in PAH patients to be half the number in healthy controls.  The new EPC capture chip has tremendous potential for serving as a rapid bedside tests to monitor treatment and disease progression. The research team includes: Georg Hansmann; B.D. Plouffe; A. Hatch; A. Von Gise; H. Sallmon; Roham T. Zamanin; Shashi Murthy. Read abstract

Epigenetic Gene Silencing May Hold Key to Pulmonary Hypertension
6/15/2010
6/11/10 (Media-Newswire.com) - A rare but fatal disease of blood vessels in the lung may be caused in part by aberrant silencing of genes rather than genetic mutation, new research reports. Pulmonary arterial hypertension, a syndrome characterized by gradual blockage of blood vessels in the lungs, has been linked to genetic causes in a small percentage of patients. But University of Chicago researchers have now found that a form of epigenetics -- the modification of gene expression -- causes the disease in an animal model and could contribute to the disease in humans. Published in the American Heart Association journal Circulation, the finding opens a promising avenue for research into the origins of vascular disorders. Read press release

The Role of the Protein HIF-2-Alpha in Chuvash Polycythemia, a Disease Associated with PH
2/22/2010
2/9/10 (Journal of Clinical Investigation) - Individuals with a condition known as Chuvash polycythemia, which is caused by a specific mutation in the protein VHL, have a greater proportion of their blood volume occupied by red blood cells than do healthy individuals. They also have pulmonary hypertension and increased respiratory rates, although the mechanistic basis for these symptoms has not been determined. Now, Celeste Simon and colleagues at the University of Pennsylvania School of Medicine, Philadelphia, have identified a role for the protein HIF-2-alpha in the lung complications of Chuvash polycythemia by studying mice that model the condition. Of particular interest, HIF-2-alpha activity was found to be increased in lungs from mice that model Chuvash polycythemia. Further, as loss of one copy of the gene responsible for generating HIF-2-alpha in mice that model Chuvash polycythemia suppressed both the polycythemia and pulmonary hypertension, the authors suggest that inhibiting HIF-2-alpha might provide a new approach to treat Chuvash disease.
