Evaluation of the Prevalence of Anti-transglutaminase 2 and 6 Antibodies in Patients with Sero-Positive Multiple Sclerosis

Background

Gluten sensitivity (GS) is one of the gluten-related disorders (GRDs). Patients with GS may have serum antibodies against tissue transglutaminase (tTG) (IgA and IgG) without any evidence of enteropathy. We aimed to evaluate both tTG-6 and tTG-2 antibodies to determine the prevalence of seropositive tTG-2 and tTG-6 antibodies in patients with multiple sclerosis (MS).

Methods

In this cross-sectional study, we carried out serological tests (IgA & IgG anti-tTG-6 and tTG-2 antibodies) in patients with MS.

Results

Seventy-two patients with MS were included in this study. Of them, seropositive patients for total (IgA+IgG) of tTG-6 and tTG-2 autoantibodies were 9.7% (95% CI, 4.2-18) and 5.6% (95% CI, 1.4-12.5), respectively.

Conclusion

Anti-tTG-6 antibody testing may be necessary for early diagnosis of GS in patients with MS. More studies with larger sample sizes are warranted to confirm these data.

Celiac disease in Iran: a systematic review and meta-analysis

Introduction

Celiac disease (CD) is a chronic autoimmune-mediated disorder with both intestinal and systemic manifestations. The aim of this study was to determine the prevalence of celiac disease in Iran.

Methods

We conducted a systematic search on Embase, Pub Med, Web of Science, Google Scholar, MagIran, Scientific Information database (SID) and Iranmedex from 2003 through to November 2015. The Der-Simonian/Laird’s (DL), with a 95% confidence interval employed to estimate the overall pooled prevalence. Heterogeneity was investigated by using subgroup analysis based on sample size and time of study.

Results

Sixty-three studies with 36,833 participants met inclusion criteria for analysis. The overall prevalence of celiac disease in 63 studies that had used serological tests for the diagnosis was observed as 3% (95% CI: 0.03–0.03) and the overall prevalence of celiac disease in studies that had used biopsy method for diagnosis was observed as 2% (95% CI: 0.01–0.02).

Conclusion

The prevalence of celiac disease in Iran was similar or even higher than world-wide reported.

Assessing of Celiac Disease and Nonceliac Gluten Sensitivity

The publication of papers on the topic of gluten related disorders has substantially increased over the last few years. This has motivated healthcare professionals to pay attention not only to celiac disease and wheat allergy but also to a condition termed nonceliac gluten sensitivity (NCGS). Until now this condition has been diagnosed clinically on the basis of exclusion criteria and clinical response to gluten withdrawal. In addition, recent research in this field has shown that other food components distinct from gluten are implicated in NCGS cases, thereby changing our general understanding of NCGS diagnosis in either individuals on gluten containing diets or those already following a gluten-free diet with no proper diagnostic work-up of celiac disease. With this in mind, the assessment of NCGS will require extensive knowledge of celiac disease manifestations and the laboratory tests commonly performed during diagnosis of celiac disease.

Phenotypical characterization of the peripheral blood T cells in patients with celiac disease: does it differentiate suspicious celiac disease cases?

AIM

The present study aimed to study the immunological changes seen in the intestinal epithelium of the celiac patients could also be detected in the peripheral blood lymphocyte populations.

BACKGROUND

Celiac disease (CD) is a small bowel enteropathy caused by permanent wheat gluten intolerance. One of the earliest signs of CD is an increase in the numbers of the intestinal intraepithelial lymphocytes (iIEL).

PATIENTS AND METHODS

In this case-control study, totally 13 untreated subjects with acceptable criteria for CD without any complication and 16 healthy subjects without any positive criteria for CD were selected. Peripheral blood T cells were analyzed by two-color flow cytometry in both groups.

RESULTS

The mean age of patients was 33.6 ± 3.4 years and two patients had Marsh IIIB, five patients had Marsh IIIA and six patients had Marsh II histology class. The mean percentages of the TCR(+) T cells in the patients were significantly higher than the controls (p=0.015). However, the mean percentages of the αβTCR(+) T cells were significantly lower in the untreated patients than the controls (p=0.025). There were no significant difference between the mean percentages of lymphocytes expressing the CD3, CD4 and CD8 molecules in the patients and the controls.

CONCLUSION

The change in the percentages of the peripheral blood T cells expressing the γδTCR and αβTCR in the celiac patients could be used in conjunction with the other serological markers to identify new CD cases.
