RESUMEN
AIM: Assess the characteristics of break through COVID-19 in Inflammatory Bowel Disease (IBD) patients, despite complete vaccination. METHODS: Patients who reported a COVID-19 at least 3 weeks after complete vaccination were asked to answer an on-line anonymous questionnaire which included patient and disease characteristics, vaccination history, and the evolution of COVID-19. RESULTS: Among 3240 IBD patients who reported complete vaccination between 1st May 2021 and 30thJune 2022, 402 (12.4%) were infected by SARS Cov-2 [223 male, 216 Crohn's disease (CD), 186 Ulcerative Colitis (UC), mean (SD) age 42.3 (14.9) years, mean (SD) IBD duration 10.1 (9.7) years]. Three hundred and sixty-nine patients (91.8%) were infected once and 33 (8.2%) twice. The mean (SD) time between last vaccination and infection was 4.1 (1.6) months. Overall, 351 (87.3%) patients reported mild constitutional and/or respiratory symptoms, 34 (8.4%) were asymptomatic and only 17 patients (4.2%) required hospitalization. Of hospitalized patients, 2 UC patients died of COVID-19 pneumonia. The remaining hospitalized patients did not need high flow oxygen supply or ICU admission. CONCLUSIONS: A minority of completely vaccinated IBD patients developed COVID-19 which evolved with mild symptoms and a favorable outcome. These results reinforce the importance of vaccination especially in vulnerable populations.

BACKGROUND: The benefits of fibrinogen concentrate in hypofibrinogenaemia have been established in congenital and has been used in acquired disorders. Most European countries have already changed their practice, using fibrinogen concentrate. METHODS: We compared the use of fibrinogen concentrate in acquired hypofibrinogenaemia to cryoprecipitate, which continues to be the standard of care in the UK. We undertook a retrospective analysis of fibrinogen increment in patients treated for acquired hypofibrinogenaemia. RESULTS: Sixty four transfusion episodes receiving cryoprecipitate and 36 episodes receiving fibrinogen concentrate were compared. The median increment following 10 donor pools (two bags) of cryoprecipitate was 0.26 g/l, compared to 0.44 g/l following 2g of fibrinogen concentrate. CONCLUSION: With its superior safety profile from infectious diseases, this provides further evidence to support the use of fibrinogen concentrate.
