ABSTRACT Coeliac disease (CD) is associated with an increased risk of non-Hodgkin lymphoma (NHL), but there is little information about whether this is true for clinically silent CD.
To investigate the frequency of CD in two European populations; one with NHL and another derived from the general population.
A prospective, multi-centre, case-control study in 10 European countries was conducted between May 1998 and April 2001. A total of 1446 consecutive patients with newly diagnosed NHL aged over 18 years was collected. The control group consisted of a population of 9676 individuals who were screened for CD. The number of patients with a previous diagnosis of CD and those with silent CD detected by screening were determined in the two groups.
The patients with CD had a significantly increased risk of developing NHL [odds ratio (OR) 2.6, 95% confidence interval (CI) 1.4-4.9]. This risk was only present in patients with CD diagnosed clinically before the study (OR 3.3, 95% CI 1.4-7.9), but not in those with silent CD detected by screening (OR 1.3, 95% CI 0.6-2.7).
Patients with CD have an increased risk of developing NHL, although this is lower than previously thought. Clinically silent CD is rare in patients with NHL.

    ABSTRACT: The prevalence of celiac disease is rising. As a result there is increasing interest in the associated mortality and morbidity of the disease. Screening of asymptomatic individuals in the general population is not currently recommended; instead, a strategy of case finding is the preferred approach, taking into account the myriad modes of presentation of celiac disease. Although a gluten-free diet is the treatment of choice in symptomatic patients with celiac disease, there is no consensus on whether institution of a gluten-free diet will improve the quality of life in asymptomatic screen-detected celiac disease patients. A review of the studies that have been performed on this subject is presented. Certain patient groups such as those with autoimmune diseases may be offered screening in the context of an informed discussion regarding the potential benefits, with the caveat that the data on this issue are sparse. Active case finding seems to be the most prudent option in most clinical situations.

    ABSTRACT: Chronic pediatric diseases arising from early-life immune insult and postnatal immune dysfunction are among the most prevalent health challenges for children. Diseases such as childhood asthma and allergies, chronic otitis media, type 1 diabetes, childhood leukemia and pediatric celiac disease all feature dysfunctional immune responses and/or inappropriately skewed immune capacities. Additionally, these disorders have been increasing in incidence in recent years with previously identified risk factors unable to fully account for the change. Still, some treatment approaches target the initial health complaint and its symptoms without fully addressing either the underlying immune dysfunction of the initial disease or the likelihood for additional associated health risks in later life. Therefore, it is useful to understand both the nature of the immune dysfunction as well as the reported associated health risks. This review characterizes those pediatric immune dysfunctions produced by well-studied immunotoxicants and provides a matrix of those health risks that appear to be linked together via the underlying pediatric immune dysfunction. This information could lead to: 1) improved identification and treatment of underlying immune dysfunction, 2) long-term approaches to health management, and 3) improved prenatal and neonatal prevention strategies to avoid environmentally-induced immune insult and developmental immunotoxicity.

    ABSTRACT: Due to its high prevalence, celiac disease is a major health problem. Because of the long-term complications and difficulty of diagnosing this disease, the need for population-based screening has been raised. Serological methods for detection of celiac disease include antiendomysial and antitransglutaminase antibody detection, which has high sensitivity and specificity (nearly 100%) in forms with atrophy and low sensitivity and specificity (between 15 and 30%) in patients with minimal lesions, thus posing diagnostic difficulties in this group of individuals. The risk of late complications is unknown in this group of patients with lymphocytic enteritis. However, this group may be just as symptomatic as patients with atrophy and consequently would also benefit from a gluten-free diet. Systematic screening allows a greater number of patients with gluten-sensitive enteropathy to be detected. However, there are insufficient data to be able to evaluate the economic and social impact of systematic screening.
