Introduction: Diagnosing moderate haemophilia A (MHA) solely based on deficient FVIII protein levels limits its optimal management and delays the initiation of prophylaxis. Updating protocols and incorporating new variables into its diagnosis could prevent underestimating disease severity, avoiding early arthropathies and impairing patients' quality of life.

Aim: To propose recommendations to improve the comprehensive management of people with MHA.

Article Synopsis
  • A retrospective study in Spain and Portugal evaluated the real-world effectiveness of lonoctocog alfa (rVIII-SingleChain), a long-acting factor VIII therapy, in patients with hemophilia A who switched from other treatments.
  • Among 29 patients, there was a significant increase in those requiring fewer weekly infusions (from 37.5% to 60.7%) and an improvement in bleeding control, with total bleeds reducing from 50 to 33 after the switch.
  • Overall, patients experienced excellent safety and efficacy, leading to improved quality of life without any reported safety issues.

Management of patients with hemophilia A (HA) requires the knowledge and experience of specialized health care professionals. However, these patients may need to be attended in emergencies, outside the referral hospital, where health care professionals do not know about hemophilia and/or new innovative treatments. This study aimed to develop a simple and practical algorithm that could be used in emergency situations by nonspecialized treaters in HA and bleeding with or without factor VIII (FVIII) inhibitors under emicizumab prophylaxis.

Tumour lysis syndrome (TLS) is a life-threatening emergency characterised by a massive cytolysis with the release of intracellular electrolytes, nucleic acids, and metabolites into the circulation. TLS comprises laboratory derangements (hyperuricaemia, hyperkalaemia, hyperphosphataemia, and hypocalcaemia) responsible for acute kidney injury. In patients with hematologic malignancies after cytotoxic therapy or spontaneously and also in advanced solid tumours.
