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

Quality of life post-BMT

Splenectomy and BMTEnlarged spleen per se is not associated with higher rejection ratesMay increase transfusion requirements and delay engraftmentSplenectomy may be associated with increased transplant-related mortality. Mathews et al. Pediatr Transplant. 2009;13(2):171–176


Hepatitis C and BMTNo 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 fibrosisErer et al. Bone Marrow Transplant.,1994;14(3):369–372Angelucci 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

A global perspective

Thalassemia in Pakistan

• Thalassemia carriers 5% population

• 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

Indirect positive effects of BMT

Increases awareness about thalassemia

Attracts families for screening

Generates resources for supportive care and prevention

Increase compliance with chelation and use of safe blood

Attracts and motivate professionals

Empowers medical centers and paves the way for the cure of related disorders

Accessible HLA screening

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 transplantationConclusions 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
