July 10, 2017 Immunoglobulin E: 5 KU/L July 10,2017 My RBC and Hemoglobin have come up and are normal. My iron levels will get high (too high) when I take 65 mg elemental iron twice a day for several weeks but my ferritin has never gotten over 42 ng/mL. When I stop taking my iron supplement my iron and ferritin plummet in just a matter of weeks. My hair is falling out, I get rapid heartbeat when I get too low on iron and if I get my iron too high. My whole body hurts especially my finger joints, back , knees and really all of my joints. Going to the bathroom at least 2 times day and sometimes up to 5 times a day. Extreme fatigue, Brain fog, extremely emotional and irritable. I just went gluten free July 1, 2017 and am starting to feel better. Joints feel better, I can sleep better, my mood is better. Celiac or maybe just gluten sensitive? Any thoughts? What do my labs say about me?
Celiac.com 11/04/2015 - A research team that conducted an analysis of the relationship between seronegative celiac disease and immunoglobulin deficiencies also conducted a literature search on the main medical databases, which revealed that seronegative celiac disease poses a diagnostic dilemma. The research team included F. Giorgio, M. Principi, G. Losurdo, D. Piscitelli, A. Iannone, M. Barone, A. Amoruso, E. Ierardi, and A. Di Leo. They are variously affiliated with the Section of Gastroenterology at University Hospital Policlinico, Department of Emergency and Organ Transplantation at University of Bari in Bari, Italy. They note that villous blunting, intraepithelial lymphocytes (IELs) count and gluten "challenge" are the most reliable markers in addressing seronegative celiac disease. They also note that immunohistochemistry/immunofluorescence tissue transglutaminase (tTG)-targeted mucosal immunoglobulin A (IgA) immune complexes in the intestinal mucosa of seronegative celiac disease patients may be useful. In the team's view, tTG-mRNA was similarly increased in seropositive celiac disease and suspected seronegative celiac disease, and strongly correlated with the IELs count. This increase is found even in the IELs' range of 15-25/100 enterocytes, suggesting that there may be a "grey zone" of gluten-related disorders. An immune deregulation, severely lacking B-cell differentiatio, underlies the association of seronegative celiac disease with immunoglobulin deficiencies. Therefore, celiac disease may be linked to autoimmune disorders and immune deficits, known as common variable immunodeficiency (CVID)/IgA selective deficiency. CVID is a heterogeneous group of antibody dysfunction, whose association with celiac disease revealed only by a positive response to a gluten-free diet. The research team suggests a possible familial inheritance between celiac disease and CVID. Selective IgA deficiency, commonly associated with celiac disease, accounts for IgA-tTG seronegativity. Selective IgM deficiency (sIgMD) is rare, with less than 300 documented cases, and is connected to celiac disease in 5% of cases. The team diagnosed seronegative celiac disease in a patient affected by sIgMD using the tTG-mRNA assay. One-year on a gluten-free diet restored IgM levels. This study data support a link between seronegative celiac disease and immunoglobulin deficiencies, and invites researchers to take a closer look at this connection.

Celiac.com 12/12/2012 - In duodenal biopsy samples from people with active celiac disease, the transferrin receptor, CD71, is up-regulated, and promotes retro-transport of secretory immunoglobulin A (SIgA)-gliadin complexes. To better understand how interactions between SIgA and CD71 promote transepithelial transport of gliadin peptides, a team of researchers set out to determine if interactions among secretory immunoglobulin A, CD71, and transglutaminase-2 affect permeability of intestinal epithelial cells to gliadin peptides. The research team included C. Lebreton, S. Ménard, J. Abed, I.C. Moura, R. Coppo, C. Dugave, R.C. Monteiro, A. Fricot, M.G. Traore, M. Griffin, C. Cellier, G. Malamut, N. Cerf-Bensussan, and M. Heyman. They are affiliated with the Mixed Research Unit 989 of the National Institute of Health and Medical Research (INSERM UMR989) in Paris, France. For their study, the team evaluated duodenal biopsy specimens from 8 adults and 1 child with active celiac disease. The team used fluorescence-labeled small interfering RNAs against CD71 to transfect Caco-2 and HT29-19A epithelial cell lines. They used flow cytometry, immunoprecipitation, and confocal microscopy to assess interactions among IgA, CD71, and transglutaminase 2 (Tgase2). They then assessed transcytosis of SIgA-CD71 complexes and intestinal permeability to the gliadin 3H-p31-49 peptide in polarized monolayers of Caco-2 cells. To assess physical interplay between SIgA and CD71 or CD71 and Tgase2 at the apical surface of enterocytes in biopsy samples and monolayers of Caco-2 cells, the team used fluorescence resonance energy transfer and in situ proximity ligation assays. They co-precipitated CD71 and Tgase2 with SIgA, bound to the surface of Caco-2 cells. They found that SIgA-CD71 complexes were internalized and localized in early endosomes and recycling compartments, but not in lysosomes. In the presence of celiac IgA or SIgA against p31-49, transport of intact 3H-p31-49 increased significantly across Caco-2 monolayers, while soluble CD71 or Tgase2 inhibitors interfered with transport. Once it binds to apical CD71, SIgA (with or without gliadin peptides) enters a recycling pathway and avoids lysosomal degradation; this process allows apical-basal transcytosis of bound peptides. This mechanism is assisted by Tgase2 and might be involved in the pathogenesis of celiac disease. Source: Gastroenterology. 2012 Sep;143(3):698-707.e1-4. doi: 10.1053/j.gastro.2012.05.051.
