Abstract
Eating disorders (EDs) are increasingly frequent. Their pathophysiology involves disturbance of peptide signaling and the microbiota–gut–brain axis. This study analyzed peptides and corresponding immunoglobulin (Ig) concentrations in groups of ED. In 120 patients with restrictive (R), bulimic (B), and compulsive (C) ED, the plasma concentrations of leptin, glucagon-like peptide-1 (GLP-1), peptide YY (PYY), and insulin were analyzed by Milliplex and those of acyl ghrelin (AG), des-acyl ghrelin (DAG), and α-melanocyte-stimulating hormone (α-MSH) by ELISA kits. Immunoglobulin G (in response to an antigen) concentrations were analyzed by ELISA, and their affinity for the respective peptide was measured by surface plasmon resonance. The concentrations of leptin, insulin, GLP-1, and PYY were higher in C patients than in R patients. On the contrary, α-MSH, DAG, and AG concentrations were higher in R than in C patients. After adjustment for body mass index (BMI), differences among peptide concentrations were no longer different. No difference in the concentrations of the IgG was found, but the IgG concentrations were correlated with each other. Although differences of peptide concentrations exist among ED subtypes, they may be due to differences in BMI. Changes in the concentration and/or affinity of several anti-peptide IgG may contribute to the physiopathology of ED or may be related to fat mass.

Abstract
Studies of 521 sera from the Icelandic cousin marriage project were made to assess the incidence of various anti-tissue antibodies and the levels of immunoglobulins, as these were considered to be useful markers of the humoral immune response. Comparisons were made between these parameters and the HLA-A and B antigens, the blood groups, the immunoglobulin allotypes (Gm, Km and Am), the properdin factor (Bf), and other markers. These investigations offered another approach to the study of the sites of action of immune response genes in man. Because the immune response may be expected to differ for each individual and depend at least in part, on the degree of exposure to different antigens, no absolute correlation was expected. There was, however, a marked association between certain IgG anti-tissue antibodies and HLA antigens. This was most marked for HLA-A10, B18 and b27, but not for HLA-A1 or B8. The comparison of immunoglobulin levels with HLA antigens, was less striking, although HLA-A2 appeared to be associated with low levels of IgE. There were also some associations between immunoglobulin levels and ABO blood groups.

Abstract
Antibodies purified from sera of patients with Burkitt's lymphoma by absorption onto and elution from cultured lymphoblastoid cells, were labeled with 125I and repurified by repeating the absorption-elution procedure. The doubly purified antibodies could bound with a high degree of efficiency to immunoadsorbents prepared by entrapping in polyacrylamide gel normal human serum or exudate fluids from patients with ovarian or breast cancer. Binding was specific, as it could be inhibited by high dilutions of human sera but not by animal sera. Globulin fractions of human sera were strongly inhibitory. Their capacity to inhibit was lost after treatment with rabbit anti-human IgG serum, indicating that at least part of the inhibition could be ascribed to antibodies. Some inhibitory activity was also found, however, in the "albumin" fractions of sera, suggesting that an antigen was also involved. It appears, therefore, that practically all human sera contain antibodies reacting with an antigen(s) which is present on human cells and is also circulating freely in serum and other body fluids. Sera of patients with Burkitt's lymphoma contained, on the average higher concentrations of these antibodies, as compared to sera of individuals not suffering from this disease. This antigen is thought to be associated with the cell membrane and has been identified in cells of widely differing origin.
