Quality of life post-BMT
Caocci G, et al. EBMT 2012: P1034
54 patients (26 females and 28 males) after a mean of 20
years from sibling donor BMT compared to 41 sibling donors.
Mean age at BMT 14 yrs (currently 38 yrs) and 18 (currently
41 yrs) for patients and donors, respectively. Chronic graft
versus host disease reported in 18.5%.
Patients had lower QoL scores for vitality, physical & social
functioning

Splenectomy and BMT
 Enlarged spleen per se is not associated with higher
rejection rates
 May increase transfusion requirements and delay
engraftment
 Splenectomy may be associated with increased transplantrelated mortality. Mathews et al. Pediatr Transplant. 2009;13(2):171–176
Bone marrow and stem cell transplantation
Hepatitis C and BMT
 No evidence that BMT has any influence on the course
of HCV infection or vice versa.
 Hepatitis C and iron overload may accelerate
progression of liver fibrosis
Erer et al. Bone Marrow Transplant.,1994;14(3):369–372
Angelucci et al. Blood, 2002;100(1):17–21
HCV positivity may thus actually strengthen the indication
for BMT if proper supportive care is not available

Thalassemia in Pakistan
• Thalassemia carriers

• Total Carriers
8 million
• Thalassaemia births/year
5,000 – 6,000
• Thalassaemia Major prevalence
~ 60,000
• ~ 4% national health budget goes to thalassemia
care (for appropriate management it would have to increase to
40%).
• Thalassemia is the main donated blood consumer

The role of third-party international professional
organizations
 Foster the use of common protocols and procedures
 Reassure patients and professionals in the early phase
 Decrease unnecessary expenses
 Increased scientific visibility
 Support fund-development
 Provide network referrals
 Promote screening and prevention
Bone marrow and stem cell transplantation
Conclusions
 BMT outcomes are improving in parallel with supportive and thus
indications in severe thalassemia are still controversial, at least in
affluent countries
 In thalassemia-prone regions where appropriate long-term supportive
care might not be readily accessible and resources limited, BMT is
feasible, cost-effective and can save lives.
 Thalassemia associations, NGOs and professional networks may play
an important role to promote non-profit and ethical BMT programs
 In emerging countries better access to BMT may increases hope and
thus improve compliance with supportive care
 BMT programs may increase awareness, attract professionals and
promote prevention
