Early treatment aids in recovery of boy with chemotherapy-linked PAH

A 5-year-old boy with a neuroblastoma developed pulmonary arterial hypertension (PAH) after receiving high-dose busulfan to prepare for a stem cell transplant, but diagnosing his condition early and treating it with three lung pressure-lowering medications led to a full recovery. This treatment approach has significantly increased survival in children…

Study finds possible diagnostic biomarkers for idiopathic PAH

Researchers identified two genes — PRDX1 and TNFAIP3 — whose activity levels could serve as diagnostic biomarkers for idiopathic pulmonary arterial hypertension (PAH). The genes are related to ferroptosis, an iron-dependent type of cell death involved in lung diseases and previously associated with PAH. “Our comprehensive analysis…

Stem cell exosomes may be hypoxic pulmonary hypertension therapy

Exosomes — very small, sac-like structures — derived from stem cells may offer a potential treatment for hypoxic pulmonary hypertension (HPH) by preventing the abnormal growth and movement of muscle cells lining blood vessels. That’s according to data from a new study, conducted by researchers in China using lab-grown…

Looking at why clinicians prescribe PAH combination vs. monotherapy

Among U.S. healthcare providers who treat pulmonary arterial hypertension (PAH), a patient’s current treatment, PAH cause, and coexisting health issues are the factors that most influence their willingness to prescribe first-line combination therapy over monotherapy, according to a new study. Most clinicians said they felt a single tablet combination…

Lung transplant referrals lacking for PAH patients: Study

Most people with pulmonary arterial hypertension (PAH) are not referred for a lung transplant, despite clinical recommendations that referral should occur early in potentially eligible cases, a study reports. About 18% to 29% of participants with advanced functional class 4 disease, who guidelines recommend referrals for, received referrals.

Balloon pulmonary angioplasty benefits CTEPH patients: Study

Balloon pulmonary angioplasty (BPA) led to significant clinical improvements for people with chronic thromboembolic pulmonary hypertension (CTEPH) when used as an initial therapy or after a pulmonary endarterectomy (PEA) surgery, according to a global observational study. “Our data are in line with previous reports on changes of clinical and…

Outcomes after lung transplant similar in PH groups 2 and 3

The rates of long-term survival and perioperative complications after a lung transplant in people with group 2 or group 3 pulmonary hypertension (PH) aren’t significantly different from those in people who don’t have PH, a study reports. “No significant differences [between group 2 PH, group 3 PH, or no…
