Haematologists as Genetic Counsellors for Haemoglobinopathies: Are They Prepared?

Background/Objectives: In haematology, a wide range of blood disorders are hereditary. The thalassaemias are hereditary anaemias characterised by a high burden of disease at the public health level, challenging the resources of many health systems. This review focuses on thalassaemias for which many countries have developed screening and prevention programmes. To manage this heavy burden, two approaches were introduced over the years. The first one focused on reducing the annual affected births consequent to appropriate non-directive genetic counselling, offering to the parents the chance to make an informed choice concerning their reproductive lives. The second approach was related to the development of curative treatments such as haematopoietic stem cell transplantation (HSCT) in the early years, with continued ongoing efforts for improvements, followed by successful advances in gene-based holistic cures in more recent years. Genetic counselling is a vital component in successful prevention, aiming at informing individuals who are found to be carriers and couples who are both carriers with a 25% risk at every pregnancy of having an affected child in the case of recessive, Mendelian inheritance. The issues are many, and that may have to be discussed, highlighting the level of skills which a genetic counsellor is expected to possess and utilise appropriately in every counselling session. The concern is that such trained and skilled professionals are few in number and not well integrated into the multidisciplinary groups addressing the control of these complex disorders. It is our experience that for blood disorders, counselling is rarely in the hands of qualified scientists. It is our firm belief that it is necessary to incorporate genetic counselling as an integral part of haematology services. Methods: To investigate current practices we have drawn on the experience of existing programmes, as well as published literature. Results: Currently, in almost all haemoglobinopathy prevention programmes, counselling is offered by the clinicians in charge of clinical care or, in some settings, by the nurse of the clinic or the screening laboratory scientist. Conclusions: The Thalassaemia International Federation suggests and is in the process of developing special training in counselling as part of haematology training, as well as professional development modules for those already in practice. Considering the complexity of the issues that must be discussed, a multidisciplinary approach to counselling should be considered where possible.
