SUMMARY

In the early weeks of the ongoing COVID-19 pandemic, little was known about the risk factors of this novel disease in haematology patients. We therefore created a national, multi-center, retrospective study via a national consortium of haematology centres in Belgium to investigate the incidence and clinical characteristics of COVID-19 in haematology patients. By combining these data with data collected through the national public health institute Sciensano and the national Belgian Cancer Registry, we were able to show that haematology patients were at an increased risk of being hospitalised with COVID-19 (1 in 250 haematology patients versus 1 in 2000 in the general population). Furthermore, we found that patients with multiple myeloma and acute leukaemia were overrepresented in these hospitalisations. Mortality at 90 days was 38% during the first wave, compared to 19.3% in the general population. We therefore conclude that haematology patients with COVID-19 are at a significantly higher risk of both hospitalisation and death.

SUMMARY

Multiple sclerosis is considered to be an immune mediated inflammatory disorder of the central nervous system. It mainly affects young, socioeconomic active patients. Although our armamentarium for this disease has significantly evolved in recent years some patients remain refractory to conventional therapies. In these cases, autologous haematopoietic stem cell transplantation can be considered as a therapeutic option. Decreasing morbidity, mortality and increasing patient awareness have led to rising inquiry by our patients about this treatment option. With the aim of a standardised protocol and data registration, a Belgian working party on stem cell therapy in multiple sclerosis was established. In this paper, we report the consensus protocol of this working party on autologous haematopoietic stem cell transplantation in multiple sclerosis.
