As shown in Fig. 1, significantly increased MAC deposition is seen on RBCs (p < 0.0003), neutrophils (p < 0.009), and platelets (p < 0.0003), but not on monocytes (p=0.5, not shown). PubMed:29929138
However, in primary Cys89Tyr CD59 deficiency and not in PNH, the endothelial cells are exposed to MACmediated injury. PubMed:29929138
Although aggregation has not been investigated in PNH, we clearly show here that in primary Cys89Tyr CD59 mutation there is a significant increase in coaggregation with high numbers of activated platelets adhering to a single monocyte, and granulocytes to monocytes, that may lead to nonendothelial-bound arterial occlusion, among other effects [36].

The Cys89Tyr mutation in CD59 was initially described with manifestation in infancy by chronic hemolysis and relapsing peripheral demyelinating disease resembling recurrent Guillain- Barre syndrome (GBS) or chronic inflammatory demyelinating polyneuropathy (CIDP). PubMed:29929138

More recently, we have described two infants carrying the mutation who manifested with recurrent strokes [8], establishing the concept that primary Cys89Tyr mutation in CD59 leads to a thrombophilic state. PubMed:29929138

In summary, thrombosis is an extremely important prognostic factor both in PNH and in primary Cys89Tyr nonfunctioning CD59. PubMed:29929138
Nonfunctioning CD59 is a major risk factor for stroke and hypercoagulability. PubMed:29929138

We recently encountered patients with recurrent strokes leading to premature death in 2/7 young children with primary Cys89Tyr CD59 deficiency [8]. PubMed:29929138

We have assessed the presence of MPs in four patients with primary Cys89Tyr mutation in CD59 and two PNH patients, as well as in four healthy donors. PubMed:29929138
In summary, patients with primary Cys89Tyr mutation in CD59 showed about 9–10-fold increase in the number of MPs compared to controls and slightly but significantly increased numbers when com pared to PNH patients. The origin of MPs was primarily RBCs and to a much lesser extent platelets and neutrophils. PubMed:29929138
The average mean fluorescence (MF) for CD61 staining of was slightly reduced in patients with primary Cys89Tyr CD59 deficiency and PNH as compared to controls. However, the average MF for CD62P expression in the healthy individuals was 38.3 ± 3.1 compared to 48.5 ± 4.7 in patients with primary Cys89Tyr CD59 deficiency (p < 0.0085) and 54.0 ± 4.2 in patients with PNH (p < 0.0013), indicating a significantly more activated platelet phenotype in both the patients with PNH and those with primary Cys89Tyr CD59 deficiency. PubMed:29929138
It is thus plausible to suggest that the increased monocyte-platelet interaction in patients with primary Cys89Tyr mutation in CD59 is related to an activated platelet phenotype. PubMed:29929138
Interaction between monocytes and platelets was suggested to be via p selection [17], which was shown here to be much higher in patients with primary Cys89Tyr mutation in CD59. PubMed:29929138
High free hemoglobin was shown in patients with primary Cys89Tyr mutation in CD59 (Table 1) and it has been suggested in several ways that free hemoglobin may serve as a major mechanism for thrombophilia. PubMed:29929138
Although aggregation has not been investigated in PNH, we clearly show here that in primary Cys89Tyr CD59 mutation there is a significant increase in coaggregation with high numbers of activated platelets adhering to a single monocyte, and granulocytes to monocytes, that may lead to nonendothelial-bound arterial occlusion, among other effects [36].
