Attitudes Toward Genetic Testing for Celiac Disease

Accuracy of the clinical indicators of ineffective health management in celiac people

OBJECTIVE

to analyze the accuracy of clinical indicators of "Ineffective health management" in celiac patients and to verify associations between sociodemographic characteristics and clinical indicators.

METHOD

a cross-sectional study, conducted from May to September 2017, with 83 celiac patients, through an interview. Accuracy measures were defined by latent class model.

RESULTS

there was a prevalence of "Ineffective health management" of 55.69%. "Failure to take action to reduce risk factor" and "Failure to include treatment regimen in daily living" better predict this diagnosis. Paid occupation reduces the chance of the presence of "Difficulty with prescribed regimen". Participation in support association reduces the chance of the presence of "Difficulty with prescribed regimen", "Ineffective choices in daily living for meeting health goal" and "Failure to take action to reduce risk factor".

CONCLUSION

accurate clinical indicators identification assists clinical reasoning for diagnostic inference in specific health contexts.

HEALTH CONTROL FOR CELIAC PATIENTS: AN ANALYSIS ACCORDING TO THE PENDER HEALTH PROMOTION MODEL

ABSTRACT Objectives: to describe the health control habits that influence the daily life of celiac patients and to analyze the practice of actions related to health control and its determinants, from the perspective of the first component of the Pender Health Promotion Model. Method: a cross-sectional study conducted through interviews with instrument with 83 individuals from Ceará and diagnosed with celiac disease. Data was analyzed using the characteristics and individual experiences component of Pender's theoretical model. Results: of the celiac patients, 96.4% did not follow the gluten-free diet; 80.7% had inappropriate behaviors to reduce risk factors; 72.3% made ineffective choices in daily life to achieve health goals and; and 25.3% could not keep the gluten free diet in their daily life. Conclusion: according to the theoretical model, celiac patients did not adhere to the proper diet and presented factors inherent to daily life and social issues, characterized as barriers to an effective health control.

Familial implications of autoimmune disease: Recurrence risks of alopecia areata and associated conditions in first-degree relatives

Alopecia areata (AA), a complex autoimmune hair loss condition, affects approximately 2.1% of the population. Individuals with AA have increased susceptibility to diseases such as atopy and autoimmune disorders, but little is known about first-degree relatives' risk to develop AA and associated conditions. Genetic counseling for multifactorial conditions, including autoimmune disease is complex, but potentially valuable. Anecdotally we know patients with AA ask medical providers about recurrence risk for family members as well as question whether they and their relatives are at risk for other conditions. Data on AA recurrence risks and comorbid conditions among relatives of affected individuals comprise valuable information that may guide clinical management by genetic counselors. This study investigated the recurrence risk of AA and compared the prevalence of associated conditions among first-degree relatives to the general population. The study also assessed the validity of self-reported conditions for a subset of participants. Relatives of individuals with AA (N = 155), recruited from the National Alopecia Areata Foundation Registry, completed telephone surveys about their personal medical history for 70 medical conditions associated with AA. Medical records for 60 participants were compared to self-reported responses. One-sided proportional tests, in which it is assumed the disease prevalence in first-degree relatives is higher than for those in the general population, yielded a 7.8% estimated risk of AA versus the general population prevalence of 2.1%. Furthermore, there are increased risks of 33 associated conditions, including atopy and other autoimmune conditions. Comparison of medical reports to self-reported conditions indicated only 12% was incongruent. The findings may help genetic counselors better serve patients and their families by informing them of lifetime risk estimates of developing AA and comorbid conditions, resulting in early diagnosis of autoimmune diseases in AA families. Findings also provide evidence supporting the validity of self-report data in AA families.

Potential risk factors for celiac disease in childhood: a case-control epidemiological survey

Background: Celiac disease (CD) prevalence has increased significantly in recent decades in some developed countries. Yet the environmental factors in the existing literature do not appear to provide a satisfactory explanation for this increase.

Objective: To determine whether nine variables are associated with CD in children. These variables are: incidence of ear infection before 2 years old, courses of antibiotics before 2 years old, duration of breastfeeding, vitamin D drop exposure in infancy, vitamin D supplement exposure between 2–3 years old, age at gluten introduction into the diet, fat content of cow’s milk consumed between 2–3 years old, quantity of cow’s milk consumed between 2–3 years old, and type of water consumed at 2 years old.

Methods: An Internet-based survey was conducted among parents living in the US with at least one biological child between 3 and 12 years old. Potential participants were informed about the survey through social media, websites, electronic newsletters, and advertisements.

Results: After exclusions, there remained 332 responses associated with children with CD (cases), and 241 responses associated with children who do not have CD (controls). In this data set, skim milk as the primary form of liquid cow’s milk consumed between 2–3 years old (adjusted odds ratio [aOR]=3.556, CI=1.430–10.22, P=0.010), vitamin D drops administered for more than 3 months (aOR=1.749, CI=1.079–2.872, P=0.025), courses of antibiotics (aOR=1.133, CI=1.037–1.244, P=0.007), and incidence of ear infection (aOR=1.183, CI=1.041–1.348, P=0.010) are all associated with CD in children.

Conclusions: This study is the first to find an association between skim milk consumption and CD and vitamin D drop use for greater than 3 months and CD. It also adds to evidence that early life exposure to antibiotics and early life infection, specifically ear infection, are associated with CD.

Survey on knowledge, attitude, acceptance and related factors among pregnant women in Thailand regarding antenatal thalassaemia screening

Thalassaemia is a common haematologic health condition in Southeast Asian countries (SEA) including Thailand. Reducing the birth of new thalassaemia cases is an effective method to control disease. The background level of knowledge and attitude of pregnant women on the disease influences their decision to perform antenatal screening. Unfortunately, the information about pregnant women's knowledge and attitude on antenatal thalassaemia screening in a developing country such as Thailand is lacking. We therefore conducted this cross-sectional study to examine patients' knowledge and to evaluate the factors which influence the patient's knowledge and attitude on antenatal thalassaemia screening. 1006 pregnant women who attended antenatal care at the Maha Chakri Sirindhorn Medical Center, Faculty of Medicine, Srinakharinwirot University, Ongkharak, Nakhon Nayok, Thailand were enrolled. We found that women's knowledge on antenatal thalassaemia screening is low. A maternal age of ≥35 years was associated with a higher level of knowledge. A higher level of education and multigravidity, a family history of thalassaemia and a positive level of attitude were found more likely to have higher scores for knowledge. A higher level of education and level of knowledge score were also more likely to have a positive attitude score, but multigravidity negatively affected the attitude score. Effective counselling should be monitored among women with a lower levels of education, those with no family history of thalassaemia, and in primigravidas. Lastly, a concurrent Down syndrome screening or foetal sex determination may be useful incentives to encourage the decision to undergo screening. Impact statement What is already known about this subject? Screening for the paternal and maternal thalassaemia carrier status is important for reducing the incidence of severely thalassaemia-affected children. Poorer education and receiving genetic counselling for the first time were the predictive factors for the low post-counselling knowledge in genetic counselling before second trimester genetic amniocentesis. What do the results of this study add? Pregnant women's knowledge of antenatal thalassaemia screening was low. We found that pregnant women aged ≥35 years had a higher level of knowledge. Women with a higher level of education, multigravidity, the presence of a family history of thalassaemia and a positive attitude were more likely to have higher scores for knowledge. A higher level of education and level of knowledge score were also more likely to have a positive attitude score but multigravidity negatively affected the attitude score. The encouraging factors, such as an adjunctive Down syndrome screening or foetal structural screening or foetal sex determination may be useful as the incentive tools. What are the implications of these finding for clinical practice and/or further research? The awareness of a possible incorrect understanding is important for the antenatal counselling in the developing countries. Intensive monitoring of effective counselling using a post-counselling test should be scheduled. The methods of effective counselling for antenatal thalassaemia in developing countries should be evaluated.
