The serum levels of beta 2-microglobulins (beta 2-m) were studied in 65 celiac children. Significant statistical differences (p less than 0.05) were found between the values of patients on a gluten-containing diet (mean +/- SD, 1.92 +/- 0.64 mg/L) and those on a gluten-free diet for less than (mean +/- SD, 2.38 +/- 0.76 mg/L) or greater than (mean +/- SD, 1.46 +/- 0.77 mg/L) 8 months. A significant difference was also found between the first group and the 15-subject control group, who underwent intestinal biopsy for low stature or chronic diarrhea but had normal intestinal mucosa (mean +/- SD, 1.56 +/- 0.42 mg/L). Serum beta 2-m levels were above normal values (less than 2 mg/L) in 10 of 26 (38.5%) celiac patients on a gluten-containing diet and in two of 15 (13.3%) subjects of the control group. The beta 2-m values of patients on a gluten-free diet for less than or equal to 8 months were significantly different (p less than 0.001) from those of patients on a gluten-free diet for greater than 8 months, as well from those of the control group. No significant differences were found between patients on a gluten-free diet for greater than 8 months and the control group. A significant correlation between the antigliadin antibody (AGA) IgA and beta 2-m in the patients on a gluten-free diet for greater than 8 months and control-group patients was found.(ABSTRACT TRUNCATED AT 250 WORDS)

D007070 Immunoglobulin A Represents 15-20% of the human serum immunoglobulins, mostly as the 4-chain polymer in humans or dimer in other mammals. Secretory IgA (IMMUNOGLOBULIN A, SECRETORY) is the main immunoglobulin in secretions. IgA,IgA Antibody,IgA1,IgA2,Antibody, IgA

D012044 Regression Analysis Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.

D002446 Celiac Disease A malabsorption syndrome that is precipitated by the ingestion of foods containing GLUTEN, such as wheat, rye, and barley. It is characterized by INFLAMMATION of the SMALL INTESTINE, loss of MICROVILLI structure, failed INTESTINAL ABSORPTION, and MALNUTRITION.

D004797 Enzyme-Linked Immunosorbent Assay An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
