CENPB and pulmonary arterial hypertension: What is known in the population of SSc antibody patients is that patients with anti-Cenp-B antibodies (usually LcSSc patients) more frequently develop pulmonary arterial hypertension (PAH) and prolonged gastrointestinal transit time [30], while SSc patients with anti-Topo-I antibodies (usually DcSSc patients) are linked with a higher probability of interstitial lung disease (ILD), renal vascular damage, renal crisis, and heart fibrosis [31].
