Cerebral microbleeds (CMBs) appear to be somewhat more common in adults with hemophilia than in people who are hemostatically normal, according to a study involving 63 individuals. Participants either had hemophilia A or B (n=31) or were hemostatically normal (n=32). They underwent MRI brain scans, which investigators reviewed to determine the presence of CMBs. Among the results:
- HIV and hepatitis C virus infection were more common in patients with hemophilia.
- Smoking was more common in those who were hemostatically normal.
- Cardiovascular (CV) risk factors were similar in both groups.
- CMB prevalence was 35% in patients with hemophilia, vs 25% in hemostatically normal individuals.
- Advanced age, HCV infection history, and CV risk factors were linked with CMBs in patients with hemophilia.
- Multiple and large CMBs occurred only in the hemophilia group.
