Abstract | BACKGROUND: OBJECTIVE: The aim of the study is to evaluate in the chronic effect of cyclic intravenous Iloprost on pulmonary arterial pressure. METHODS: We studied 17 consecutive patients with CTD (14 systemic sclerosis, 3 mixed CTD) and RP, at the entry and after at least 6months of treatment of RP with cyclic Iloprost. On both occasions, in all patients we performed transthoracic Doppler echocardiography and we determined NT-proBNP plasma levels, NYHA functional class, 6 Minute-Walk Distance (6MWD). RESULTS: At follow-up (8.2±1.9months; range 6-12) mean values of pulmonary arterial systolic pressure ( PASP) significantly decreased (from 32.2±9.2 to 29.2±7.6mmHg, p<0.04) and mean values of 6MWD significantly increased (from 407.5±101.5 to 448.3±89.9m, p<0.01). Moreover, we observed a significant direct correlation between PASP and NT-proBNP values and a significant inverse correlation both between NT-proBNP and 6MWD values and between PASP and 6MWD values. CONCLUSION: Our results suggest that cyclic intravenous Iloprost may protect against the development or worsening of PAH in patients with CTD and RP.
