SUMMARY

This case report outlines the diagnosis and management of T-cell prolymphocytic leukaemia (T-PLL) in a 78-year-old asymptomatic woman. The leukaemia rapidly progressed within five months, leading to a hyperleukocytosis of 305 × 109/L and thrombopenia suggestive for bone marrow involvement. Diagnostic assessments included peripheral blood analysis, immunophenotyping, cytogenetics and molecular analysis according to the unified diagnostic criteria of the T-PLL International Study Group (T-PLL-ISG). Bendamustine treatment was initiated resulting in a significant decrease in leucocytosis. In the past nine months, the patient has received six cycles of bendamustine and has remained asymptomatic to date.

SUMMARY

Despite significant advances in therapeutic modalities, the treatment of relapsed and refractory multiple myeloma (RRMM) is still challenging. In this publication, we aim to provide an update on therapeutic modalities for RRMM in Belgium. First, novel combinations of well-established therapeutic agents will be discussed. Second, T-cell redirection therapies will be addressed. These include bispecific antibodies, both anti-BCMA x CD3 and anti-GPRC5D x CD3, as well as chimeric antigen receptor (CAR) T cell therapy. Third, we discuss novel modalities such as antibody-drug conjugates, selinexor, venetoclax, melflufen and CELMoDs. Finally, a general flowchart regarding overall treatment sequencing will be proposed, providing an integrated treatment recommendation from frontline to relapse.

Systemic bevacizumab to treat refractory bleeding in hereditary haemorrhagic telangiectasia: A single centre case series

BJH - volume 14, issue 3, may 2023

J. Nelissen MD, K.L. Wu MD, PhD, N. Granacher MD, D. Breems MD, PhD

SUMMARY

Hereditary haemorrhagic telangiectasia (HHT) is a rare genetic disorder that causes mucocutaneous telangiectasia and visceral arteriovenous malformations (AVMs). Recurrent iron deficiency and anaemia are significant complications often treated by haematologists. Bevacizumab, an anti-VEGF monoclonal antibody, has been implemented to target elevated levels of VEGF as seen in HHT patients. We present a single centre case series of three patients with recurrent bleeding issues due to HHT who have been treated with bevacizumab. All three patients were benefited in terms of mean haemoglobin, need for iron infusions and number of haemostatic interventions. Based on our own case series and existing literature, systemic bevacizumab appears to be effective in the treatment of bleeding-related conditions. However, the optimal dose and treatment strategy has yet to be determined. Randomised controlled studies are needed to further support the indication of bevacizumab in HHT.

Ibrutinib and atrial fibrillation: A Belgian expert consensus paper

BJH - volume 12, issue 4, june 2021

SUMMARY

Over the last decade, the oral Bruton’s tyrosine kinase (BTK) inhibitor ibrutinib induced a paradigm shift in the treatment of patients with chronic lymphocytic leukaemia (CLL), mantle cell lymphoma (MCL), and Waldenströms macroglobulinemia (WM). In clinical trials and in real-world studies, ibrutinib proved to be an effective agent with an overall favourable safety and tolerability profile. However, compared with standard chemo-immunotherapy (CIT), ibrutinib was associated with a higher incidence of atrial fibrillation (AF). The patho-physiological mechanisms underlying this increased AF incidence are not completely understood, but it is thought to be related to off-target inhibitory effects of ibrutinib on the Tec protein tyrosine kinase (TEC) in cardiac cells. The prevalence of AF in patients treated with ibrutinib is highest during the first three months of therapy, which warrants an increased vigilance during this treatment phase. However, AF in patients treated with ibrutinib is generally well manageable without ibrutinib discontinuation. Prior to the start of ibrutinib treatment, identification and addressing modifiable risk factors for AF is a first important step. The threshold for haematologists to consult a cardiologist or a cardio-oncologist should be low and a close collaboration between both specialties is warranted. Unnecessary ibrutinib interruptions should be avoided, and uncomplicated AF is not a valid reason to discontinue or interrupt ibrutinib. If anticoagulation is required, direct oral anticoagulants are preferred. In this paper, a panel of haematology and cardiology specialists have provided practical guidance on how to evaluate patients prior to ibrutinib treatment and monitor during ibrutinib therapy. Furthermore, they have provided practical guidance on how to manage AF in ibrutinib-treated patients.

Practical management of multiple myeloma: Update 2020

BJH - volume 11, issue 8, december 2020

M.C. Vekemans MD, C. Doyen MD, K.L. Wu MD, PhD, A. Kentos MD, PhD, P. Mineur MD, L. Michaux MD, PhD, J. Caers MD, PhD, N. Meuleman MD, PhD, M. Delforge MD, PhD, On behalf of the BHS Myeloma Subgroup

SUMMARY

With the introduction of immunomodulatory drugs, proteasome inhibitors and anti-CD38 monoclonal anti-bodies, major improvements have been achieved in the treatment and outcome of multiple myeloma (MM). Different treatment combinations are now in use and other therapies are being developed. This rapidly changing therapeutic landscape urges for an update on practical guidelines. Based on an extensive review of the recent literature, we propose recommendations on myeloma management, to be used by haematologists as a reference for daily practice.

Ibrutinib and bleeding management: a Belgian expert consensus

BJH - volume 11, issue 4, june 2020

A. Janssens MD, PhD, D. Bron MD, PhD, V. Van Hende MD, V. Galle MD, K. Jochmans MD, PhD, S. Meers MD, PhD, M. André MD, PhD, M-C. Ngirabacu MD, PhD, K.L. Wu MD, PhD, B. De Prijck MD, P. Verhamme MD, PhD, C. Hermans MD, PhD

SUMMARY

In recent years ibrutinib emerged as a paradigm shifting agent in the treatment of chronic lymphocytic leukaemia (CLL), mantle cell lymphoma (MCL) and Waldenström’s macroglobulinemia (WM). In clinical trials and in real-world studies ibrutinib proved to be an effective agent with an overall favourable tolerability profile. However, compared with standard chemo-immunotherapy (CIT), ibrutinib was associated with a higher incidence of clinically significant bleeding. This has been hypothesized to be linked to the platelet-specific effects of inhibiting Bruton’s tyrosine kinase (BTK). Most bleeding events under ibrutinib are low-grade with a decreasing incidence over time. However, bleeding can have a significant impact on patients and interfere with persistence and compliance of ibrutinib treatment. Currently, no clear consensus exists on the use of ibrutinib in patients with an increased bleeding risk, on the management of ibrutinib-induced bleeding and on the use of ibrutinib around surgery or invasive procedures. In this paper, a panel of Belgian haematology and haemostasis specialists formulated practical advice on bleeding prevention and management in ibrutinib-treated patients.
