Description of the Golde score calculation in sputum macrophages.
Table 1.
Clinical characteristics of the four patient groups.
Table 2.
Clinical features suggesting the presence of PVOD, number of evaluable cells, and Golde score.
Figure 2.
Haemosiderin-laden macrophages are significantly (P<0.05) more present in sputum from PVOD patients as compared to the others (IPAH, CTEPH and SAPH, respectively).
Figure 3.
Histologic specimen from a patient suffering from PVOD who underwent lung transplantation.
Intimal thickening and fibrous obstruction of septal veins and preseptal venules (asterixis) as well as features of pulmonary capillary hemangiomatosis with proliferation of dilated and congested capillaries as well as dilated lymphatic (left upper and right lower part of the figure; arrowhead). Alveoli with haemosiderin-laden macrophages of Golde score 3–4 (arrow) are clearly visible. Haemosiderin-negativ macrophages are difficult to be identified. Golde score from the tissue was 304, as compared to 252 in the sputum.
