Assessment and treatment of pulmonary arterial hypertension: an Australian perspective in 2006.
    Internal medicine journal, 2007, Volume: 37, Issue:1

    Pulmonary arterial hypertension is a group of diseases which forms a small subset of those with elevated pulmonary artery pressure (pulmonary hypertension). The recent development of selective pulmonary vasodilator has lead to a substantial resurgence of interest in what have been previously regarded as rare and incurable diseases. This review aims to describe the spectrum of pulmonary vascular diseases, the evolving understanding as to pathogenesis, the evolving evidence of efficacy for drug therapies, trying to put this into a contemporary Australian context. Several key pathogenic pathways may be involved: prostacycline, Nitric Oxide-cGMP-phosphodiesterase 5 and endothelin- all of which are exploited for therapeutic benefit by newly available drug therapies. A recently modified classification system reasserts the importance of precise diagnosis. The cardinal symptom of exertional dyspnea warrants careful evaluation in an attempt to prevent (frequently occurring) substantial delay in diagnosis. Echocardiogram is the cornerstone of screening for pulmonary arterial hypertension; however, a detailed evaluation including a carefully performed right heart catheterisation with sufficient data to allow calculation of pulmonary vascular resistance is key to accurate diagnosis. These new approaches to therapy are already substantially improving quality of life and prognosis.

Inhaled iloprost for severe pulmonary hypertension.
    The New England journal of medicine, 2002, Aug-01, Volume: 347, Issue:5

    Uncontrolled studies suggested that aerosolized iloprost, a stable analogue of prostacyclin, causes selective pulmonary vasodilatation and improves hemodynamics and exercise capacity in patients with pulmonary hypertension.. We compared repeated daily inhalations of 2.5 or 5.0 microg of iloprost (six or nine times per day; median inhaled dose, 30 microg per day) with inhalation of placebo. A total of 203 patients with selected forms of severe pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension (New York Heart Association [NYHA] functional class III or IV) were included. The primary end point was met if, after week 12, the NYHA class and distance walked in six minutes were improved by at least one class and at least 10 percent, respectively, in the absence of clinical deterioration according to predefined criteria and death.. The combined clinical end point was met by 16.8 percent of the patients receiving iloprost, as compared with 4.9 percent of the patients receiving placebo (P=0.007). There were increases in the distance walked in six minutes of 36.4 m in the iloprost group as a whole (P=0.004) and of 58.8 m in the subgroup of patients with primary pulmonary hypertension. Overall, 4.0 percent of patients in the iloprost group (including one who died) and 13.7 percent of those in the placebo group (including four who died) did not complete the study (P=0.024); the most common reason for withdrawal was clinical deterioration. As compared with base-line values, hemodynamic values were significantly improved at 12 weeks when measured after iloprost inhalation (P<0.001), were largely unchanged when measured before iloprost inhalation, and were significantly worse in the placebo group. Further significant beneficial effects of iloprost treatment included an improvement in the NYHA class (P=0.03), dyspnea (P=0.015), and quality of life (P=0.026). Syncope occurred with similar frequency in the two groups but was more frequently rated as serious in the iloprost group, although this adverse effect was not associated with clinical deterioration.. Inhaled iloprost is an effective therapy for patients with severe pulmonary hypertension.

Aerosolized iloprost in CREST syndrome related pulmonary hypertension.
    The Journal of rheumatology, 2001, Volume: 28, Issue:10

    To assess the outcome of patients with CREST syndrome associated severe pulmonary hypertension treated by aerosolized iloprost in a noncomparative study.. Five patients with CREST syndrome associated severe pulmonary hypertension were treated with 100 microg/day of aerosolized iloprost. New York Heart Association functional class and exercise tolerance (6 min walk test) were assessed at baseline, after one month, and then every 6 months. A right heart catheterization was performed at baseline in all but one patient. Systolic pulmonary artery pressure (PAP) was measured with Doppler echocardiography after one month and every 6 months.. The mean followup was 13.2 +/- 8.8 months (median 6, range 6-24). Subjective quality of life improved in all patients. NYHA functional class decreased from Class III to II in 3 patients, from Class III to I in one patient, and from Class IV to III in one patient. At 6 months, the distance walked in 6 min had increased from 352 +/- 48 to 437 +/- 56 m (p = 0.06). At one month the mean systolic PAP was 58 +/- 13 vs 81 +/- 9 mm Hg at baseline (p = 0.04). At 6 months the mean systolic PAP was 57 +/- 13 mm Hg (p = 0.06). The improvement of both clinical and hemodynamic status was maintained in the 2 patients treated for 2 years. Neither adverse effects nor need to increase the daily dose of iloprost were observed. One patient died of right heart failure and one patient did not experience any improvement of exercise tolerance and hemodynamics.. Aerosolized iloprost might be potentially useful as treatment for CREST syndrome associated pulmonary hypertension. However, patients who could benefit from this treatment will probably have to undergo careful criteria selection.
