Show me the evidence: Effectiveness of low-dose prophylaxis.

Prophylaxis is the gold standard treatment for haemophilia but requires more amount of clotting factor concentrates, than on demand therapy. Low dose prophylaxis is an alternative for countries with limited resources. There are data of evidence showing the superiority of low-dose prophylaxis than episodic treatment. Studies from China, India, Tunisia, Thailand and Indonesia reported experiences with low dose prophylaxis using outcome assessment. These studies have shown the effectiveness of various protocols regimen with once, twice or thrice injection of 10-15 UI Kg-1 per injection. These protocols allow reduction of joint bleeds and at least delay of joint damages. There is not enough long-term data nowadays, but low dose prophylaxis is certainly better than on demand therapy and should be considered as a first step of prophylaxis in some countries but not the final goal.
