Thalassaemia in Britain: a tale of two communities. Births are rising among British Asians but falling in Cypriots

The impact of migrations on the health services for rare diseases in Europe: the example of haemoglobin disorders

Migration from different parts of the world to several European countries leads to the introduction of haemoglobinopathy genes into the population, which creates several demanding needs for prevention and treatment services for Hb disorders. In this paper we examined the degree to which European health services have responded to such challenges and in particular to health services necessary to address the needs of patients with thalassaemia and sickle cell disease (SCD). Information on available services was obtained from international organizations, collaborated European project, and the Thalassaemia International Federation (TIF) Databases, which include information from published surveys, registries, field trips, and delegation visits to countries and regions by expert advisors, local associations, and other collaborators' reports. Results show that countries with traditional strong prevention and treatment programs are well prepared to face the above challenges, while others are urgently needed to address these problems in a systematic way. The Thalassaemia International Federation (TIF) is committed to monitor the progress, raise awareness, and support the promotion of more immigrant-oriented health policies to ensure their integration in society and their access to appropriate, adequate, and timely health services.

Public perceptions and attitudes toward thalassaemia: Influencing factors in a multi-racial population

Background

Thalassaemia is a common public health problem in Malaysia and about 4.5 to 6% of the Malays and Chinese are carriers of this genetic disorder. The major forms of thalassaemia result in death in utero of affected foetuses (α-thalassaemia) or life-long blood transfusions for survival in β-thalassaemia. This study, the first nationwide population based survey of thalassaemia in Malaysia, aimed to determine differences in public awareness, perceptions and attitudes toward thalassaemia in the multi-racial population in Malaysia.

Methods

A cross-sectional computer-assisted telephone interview survey of a representative sample of multi-racial Malaysians aged 18 years and above was conducted between July and December 2009.

Results

Of a total of 3723 responding households, 2846 (76.4%) have heard of thalassaemia. Mean knowledge score was 11.85 (SD ± 4.03), out of a maximum of 21, with higher scores indicating better knowledge. Statistically significant differences (P < 0.05) in total knowledge score by age groups, education attainment, employment status, and average household income were observed. Although the majority expressed very positive attitudes toward screening for thalassaemia, only 13.6% of married participants interviewed have been screened for thalassaemia. The majority (63.4%) were unsupportive of selective termination of foetuses diagnosed with thalassaemia major.

Conclusion

Study shows that carrier and premarital screening programs for thalassaemia may be more effective and culturally acceptable in the reduction of pregnancies with thalassaemia major. The findings provide insights into culturally congruent educational interventions to reach out diverse socio-demographic and ethnic communities to increase knowledge and cultivate positive attitudes toward prevention of thalassaemia.

A holistic approach to education programs in thalassemia for a multi-ethnic population: consideration of perspectives, attitudes, and perceived needs

Hemoglobin disorders which include thalassemias are the most common heritable disorders. Effective treatment is available, and these disorders can be avoided as identification of carriers is achievable using simple hematological tests. An in-depth understanding of the awareness, attitudes, perceptions, and screening reservations towards thalassemia is necessary, as Malaysia has a multi-ethnic population with different religious beliefs. A total of 13 focus group discussions (70 participants) with members of the general lay public were conducted between November 2008 and January 2009. Lack of knowledge and understanding about thalassemia leads to general confusions over differences between thalassemia carriers and thalassemia major, inheritance patterns, and the physical and psychologically impact of the disorder in affected individuals and their families. Although most of the participants have not been tested for thalassemia, a large majority expressed willingness to be screened. Views on prenatal diagnosis and termination of fetuses with thalassemia major received mixed opinions from participants with different religions and practices. Perceived stigma and discrimination attached to being a carrier emerged as a vital topic in some group discussions where disparity in the answers exhibited differences in levels of participants' literacy and ethnic origins. The two most common needs identified from the discussion were information and screening facilities. Participants' interest in knowing the severity of the disease and assessing their risk of getting the disorder may imply the health belief model as a possible means of predicting thalassemia public screening services. Findings provide valuable insights for the development of more effective educational, screening, and prenatal diagnostic services in the multi-ethnic Asian society.

Haemoglobinopathies and glucose-6-phosphate dehydrogenase deficiency in a Scandinavian perspective

Haemoglobinopathies (mainly thalassaemia and sickle-cell anaemia syndromes) and glucose-6-phosphate dehydrogenase deficiency (G6PD) are globally among the most prevalent single-genomic diseases. About 3% of the world's population are heterozygotic for beta-thalassaemia and about 1-2% for sickle-cell anaemia, and it is estimated that more than 400 million people are affected by G6PD deficiency worldwide. The disorders are most prevalent in the Mediterranean area, in Asia and Africa. The Scandinavian countries, among others, have seen a boom in immigration during the past 20 years, and therefore migration makes haemoglobinopathies as well as G6PD deficiency increasingly more important from a differential diagnostic perspective in most countries. The purpose of the present special issue of the Journal is to summarize current epidemiological data and elucidate trends and practices in the laboratory diagnosis of these disorders.

Thalassemia treatment and prevention in Uva Province, Sri Lanka: a public opinion survey

Due to its excessive cost thalassemia management is a major health care problem in Sri Lanka. The majority of doctors are using only desferrioxamine (DFO), in grossly inadequate doses mainly because of its unavailability. Deferiprone (L1), which is more affordable, is not used due to fear of toxicity, as previously reported. Arthropathy attributed to L1 has been observed in some patients, and has led to the discontinuation of the drug in all patients, without scientific rationale. The proposed thalassemia prevention project for Uva Province is based on prevention of marriages between carriers. This could be achieved by carrier screening and counseling of teenagers and adolescents well before they select their partners. In Sri Lanka, people find their marriage partners at their work place or universities, by themselves, or with the help of professional marriage brokers (they are called Kapuwa), through relatives and close friends. This process of finding a partner may also be helped by paper advertisements. However, in addition to the appearance and attitude of the prospective partner, the caste, social background and horoscope are major considerations in selecting a partner. Even when they select partners on their own at the work place or university, they keep these factors in the back of their minds to ensure social acceptance. Many relationships are given up due to objections and advice from parents when the caste or social background does not match. A horoscope is a written document that almost every child gets, written by a professional horoscope reader and depending on the time of birth. It is believed, according to the horoscope, that a person's attitudes, desires, future prospects of finding a suitable partner, could be predicted. It is rare to proceed with a marriage if the horoscope does not match. These customs are considered less seriously among educated people when they find their partner at the work place or university. The concept of thalassemia risk-free marriages advocates promotion of marriages where at least one partner is a non-carrier. Success of such a project could be monitored at the time of marriage. This opinion survey indicates that the public is motivated to promote carrier screening and the prevention of thalassemia.

'Rakter dosh'--corrupting blood: The challenges of preventing thalassemia in Bengal, India

Thalassemia is an inherited blood disorder that has been receiving increasing attention in India. However, prevention of thalassemia in India continues to be difficult despite efforts of public health professionals and the government. Using West Bengal as a case study, this paper attempts to unravel some of the barriers to the prevention campaign and the consequent under utilization of the program. Lack of access, low awareness, low-risk perception and poverty are all important proximate constraints; however, one of the greatest barriers to the program is rooted in cultural notions of blood, marriage, identity, personhood and kinship in Bengali society. Blood is so deeply valued in the Bengali kinship system that this genetic mutation is perceived to be corrupting the blood (rakter dosh). Being a thalassemia carrier (i.e., having thalassemia minor) renders an individual unfit as a suitable marriage partner because of beliefs related to purity of blood, its association with the continuity of the lineage, and subsequent transmission of desirable traits to future generations. The risk of non-marriage affects women disproportionately, and parents are not inclined to test their daughters because of the possibility of not being able to marry them off to eligible suitors. The stigma associated with having thalassemia minor (TMI) is a deterrent to the disclosure of thalassemia status as well as to testing. Using anthropological theories and ethnographic methods, this paper focuses on the gendered process by which the diagnosis of a thalassemia carrier 'spoils' identities, thereby creating a disjuncture between the goals of the prevention program and people's need for social conformity, and ultimately between medical desirability and social desirability. The paper also suggests policies for enhancing the utilization of the program. Finally the conclusions from this study have potential applications for public health prevention programs that confront problems of stigma in program acceptability.

A qualitative study on the experiences of mothers caring for their children with thalassemia in Athens, Greece

This qualitative study investigated the caregiving experiences of mothers of children with thalassemia. Using a semistructured questionnaire, the researchers interviewed a convenient sample of 19 mothers who have children with thalassemia. A considerable failure to provide information regarding carrier testing prior to marriage or genetic screening for thalassemia during early pregnancy at the time of the participants' pregnancies was noted. Emotional distress, fear of death, and difficulties in dealing with feelings were some of the mothers' concerns. Although they reported that support was provided, approximately half of the subjects wished that support be offered on a more regular basis. Furthermore, most of the mothers stressed that, owing to the tremendous shortage of nursing staff, support services provided by nurses are difficult to obtain.

Attitudes towards prenatal diagnosis and termination of pregnancy for thalassaemia in pregnant Pakistani women in the North of England

OBJECTIVES

Most births of children affected with beta-thalassaemia major in the United Kingdom are to parents of Pakistani origin. A popular explanation for this is that Pakistanis decline termination of pregnancy on religious grounds. However, various factors influence people's attitudes towards prenatal diagnosis and termination of pregnancy, which have not been investigated in a UK Pakistani sample. This study is aimed at exploring the attitudes of pregnant Pakistani women towards prenatal diagnosis and termination of pregnancy for beta-thalassaemia major in the North of England.

METHODS

Forty-three pregnant women tested for thalassaemia carrier status were interviewed following receipt of their test results. Interviews were analysed using the grounded theory approach.

RESULTS

Findings showed: (1) women's awareness of and attitudes towards prenatal diagnosis; (2) the relationship between attitudes towards prenatal diagnosis and termination of an affected foetus; (3) the relationship between attitudes towards termination of pregnancy and religious beliefs, perceptions of severity of the condition, influence of significant others, and (4) the impact of gestational age at the time of the offer of termination of pregnancy.

CONCLUSIONS

Pakistani women's attitudes towards prenatal diagnosis and termination of pregnancy are influenced by various factors, and therefore their religion should not be taken as a proxy for their attitudes either for or against termination of pregnancy.

Ethnicity and the politics of the new genetics: principles and engagement

Identifying the genetic basis of disease is not a straightforward medical procedure but implicates the broader social, cultural and political context. Ethnicity represents an important part of this context, particularly given the confused and poorly informed debate about genetic differences among supposedly different 'racial' populations. Debates about the 'new genetics', however, have not engaged fully with the issue of ethnicity and racism. This paper, by reviewing a mix of empirical and theoretical debates, explores the discursive practices that inform current thinking on genetics, ethnicity and race. The account begins by exploring some of the philosophical tensions inherent in providing genetic testing. In doing so, the paper argues that current debates about genetics are not neutral but evoke a specific set of received ideas and codes of intervention, embodying social and power relationships. The paper then broadens the discussion by exploring the general meaning of screening and counselling for the 'lay' population, before focusing on the process of providing information and identifying people as carriers. The paper concludes by suggesting that the social space in which the 'new genetics' is enacted, understood and given meaning raises generic concerns, irrespective of ethnicity. These include the potential tension between prevention and informed decision making, whereby ideas about empowering individuals to exercise choice exist alongside a more general societal concern with minimising impairment and illness. In more practical terms, individual choice is compromised by poor-quality care, inadequate information, insensitivity to an individual's worries and concerns and a more general failure to meet his or her needs. At the same time, however, the often racialised perspectives articulated through the activities of service professionals can further complicate the choices and decisions available to minority ethnic populations. The failure to recognise and respond to diversity; blaming minority ethnic populations for their health problems; and the pervasiveness of racist myths and stereotypes in service provision, serve to disadvantage minority ethnic populations. This explains why themes such as equity and access, political engagement as well as more general notions of deservingness based on the construction of citizenship and identity emerge as fundamental in making sense of the relationship between ethnicity and the politics of the 'new genetics'.
