摘要

Paroxysmal nocturnal haemoglobinuria (PNH) was initially named 'chronic haemolytic anaemia with perpetual haemosid-ennuna and often results in iron deficiency secondary to urinary iron loss (Parker et al, 2005). Eculizumab is an inhibitor of complement component 5, which has been shown effective in the control of complement-mediated intravascular haemolysis of PNH (Hillmen et al, 2006; Kelly et al, 2011; Risitano et al, 2011). We investigated iron com-partmentalization in 20 haemolytic PNH patients: two untreated, 14 on eculizumab, and four analysed before and during eculizumab treatment (Table I). Standard biochemical testing, including iron parameters and flow cytometry for complement component 3 (C3) on erythrocytes, was combined with magnetic resonance imaging (MRI) to assess calculated iron content (CIC) of kidneys, liver and spleen (Gandon et al, 1994; Deugnier & Turlin, 2007).
