Standardized and disease-specific patient-reported outcome (PRO) instruments assessing pain, functional impairment and health-related quality of life (HRQoL) in people with haemophilia (PWH) have been used in studies, but infrequently in comprehensive care settings for individual assessment or treatment planning. ⋯ Data demonstrate challenges of predominantly ankle/knee pain and lower extremity functional impairment in US adult PWH, affecting HRQoL across PROs/HJHS.

Prior to the introduction of viral inactivation of factor concentrates and screening of blood, 225 people with haemophilia became infected with hepatitis C (HCV) in Ireland. ⋯ After 30 years of infection, 40% of the patients who had evidence of chronic HCV had developed advanced liver disease, such as cirrhosis and HCC, or had died from liver-related causes. This proportion is high relative to similar international cohorts despite good anti-HCV treatment uptake and responses.

N8-GP (turoctocog alfa pegol) is an extended half-life glycoPEGylated recombinant factor VIII (FVIII) product developed for the prevention and treatment of bleeds in haemophilia A patients. ⋯ The data showed that N8-GP was effective and well tolerated for the prevention and treatment of bleeds during major surgery; such FVIII products with extended half-lives may modify current treatment schedules, enabling fewer infusions and earlier patient discharge.
-
Haemophilia is characterized by frequent haemarthrosis, leading to acute/chronic joint pain. ⋯ Patients with chronic pain, particularly those with both acute/chronic pain, frequently experience psychological issues, functional disability and reduced HRQoL. Treatment strategies for acute pain (e.g. routine infusions to prevent bleeding) and for chronic pain (e.g. long-acting opioids) may be underused.

Fibrinogen Mahdia: A congenitally abnormal fibrinogen characterized by defective fibrin polymerization.
Congenital dysfibrinogenemia is a rare qualitative fibrinogen deficiency. Molecular defects that result in dysfibrinogenemia are usually caused by mutations which affect fibrinopeptide release, fibrin polymerization, fibrin cross-linking or fibrinolysis. ⋯ The new dysfunctional fibrinogen, Mahdia variant, describes its impact on fibrin assembly after the loss of the αC domains which are involved in the lateral aggregation of protofibrils. The study confirms that the truncated Aα-chain could be incorporated into mature fibrinogen molecules.
