There are no evidence-based guidelines on pain management in people with haemophilia (PWH), who may suffer acute, disabling pain from haemarthroses and chronic arthropathic pain. To review evidence and to investigate current clinical practice in pain assessment and management in PWH the European Haemophilia Therapy Standardisation Board undertook a literature review and a survey in 22 Haemophilia Treatment Centres (HTC), using a questionnaire and seven clinical scenarios. Consensus was sought on pain assessment and management in PWH. ⋯ Second-line therapy is heterogeneous. There is little published evidence to guide pain assessment and management in PWH, and clinical practice varies considerably across Europe. General and specific recommendations are needed.

It is not clear whether von Willebrand disease (VWD) is associated with an increased risk of postpartum haemorrhage (PPH). We assessed the effect of VWD on PPH in a case-control study. Logistic regression was used to test for differences in the odds of PPH in deliveries to women with and without VWD, before and after adjustment for known risk factors. ⋯ PPH was observed in 7/24 (29%) deliveries in women known prepregnancy to have VWD. The unadjusted odds for VWD as a risk factor for PPH in this group was significantly greater than the control group (OR 2.78 (95% CI 1.03-7.49) P = 0.043) and remained significant after adjusting for other significant risk factors (OR 3.41 (95% CI 1.07-10.9) P = 0.038). VWD in itself may not be a significant risk factor for PPH, however, women known to have VWD predelivery may represent an at risk sub-group.

Persons with haemophilia experience persistent pain resulting in chronic arthritic symptoms. The older person with haemophilia who did not benefit from primary prophylaxis are particularly at risk for persistent pain in multiple target joints as a result of repeated joint bleeding with delayed treatment received. The National Pain Study, Ref. [11] identified over 700 persons with haemophilia who rated daily persistent pain as 4.22/10 (SD ± 2.05) using a visual analogue scale. ⋯ Six of the nine subjects reported an improvement in pain scores by at least 50%. Seven of the nine quality of life (QOL) domains within the QOL SF-36 questionnaire improved, suggesting a perception by subjects of improvement. This study suggests that acupuncture therapy can be a safe additional modality for pain management therapies in persons with haemophilia, although larger randomized studies are needed for further validation.

Rare bleeding disorders (RBDs) include the inherited deficiencies of fibrinogen, factor (F)II, FV, FV+FVIII, FVII, FX, FXI and FXIII. There have been remarkable advances in understanding the molecular profiles that lead to each type of coagulation factor deficiency. ⋯ The clinical manifestations in different RBDs are heterogeneous, and the residual plasma coagulant factor level does not always predict bleeding tendency. In this review, we describe the general features and recent advances in understanding three such deficiencies: FXI, FVII and fibrinogen deficiencies.

The evaluation of the coagulation profile has used so far either clotting-based or chromogenic assays with different endpoints. Clotting-based techniques are the most used worldwide, and they certainly are useful for diagnosis of clotting factor deficiencies. However, the information provided is relatively limited, and therefore the individual profile of coagulation is poorly assessed. ⋯ If one considers that a certain level of thrombin generated would predict clinical efficacy, monitoring of thrombin formation might offer new possibilities to individually predict the bleeding phenotype, select the most adapted therapeutic product and tailor the dose. The same holds true for thromboelastography/thromboelastometry which evaluate fibrin formation as well as clot resistance to fibrinolytic challenge, one step further down in the coagulation process. In this regard, these 2 assays could be seen as complementary in terms of information provided on the coagulation profile at the individual level.
