    Abstract:
    UNLABELLED: The Rome IV criterion for a diagnosis of NUD is chronic or recurrent epigastric pain within the last 3 months and an onset of symptoms at least 6 months prior to presentation. The term functional Dyspepsia and idiopathic dyspepsia are often used as well. Symptoms include ulcer-like dyspepsia; gastroparetic-like (nausea, early satiety, and post-prandial pain), and undifferentiated. Pathogenesis of NUD is not completely known yet. Several mechanisms have been proposed to be responsible for these symptoms. Although there is strong evidence of an association between H. pylori infection and NUD, Celiac Disease and NUD. Being a tropical country, the prevalence of infections is parasitic cause. Dyspepsia is likely to be more in India. However, the present data from India as scares in literature. Hence the present study was planned to decipher the clinical profile, prevalence of H. pylori, IgA tTG, spectrum of duodenal biopsy abnormalities in NUD patients. MATERIAL: This Descriptive Observational study was carried out in the Gastro Enterology center in GOI research institute from August 2020 to March 2021. Initially, 200 dyspepsia patients were selected. 50 patients were excluded due to various reasons. Finally, 150 patients who met the Rome 4 criteria for NUD/Functional Dyspepsia were recruited. The inclusion criteria were patients above 18 years of age, dyspepsia for >/- 6 months, and no evidence of underlying malignancy, pan gastritis, previous gastric ulcers, and pancreatitis. The patients underwent routine blood investigations like haemogram and biochemistry, Rapid Urease Test (RUT), Upper Gastro-Intestinal Endoscopy, Duodenal Biopsy, and Serum IgA-tTG antibody. OBSERVATION: The mean age was 46.3 yrs. +/- 14.12 yrs, of which 49.3% were females and 50.70% were males. The prevalence of Epigastric Pain Syndrome (EPS) was found in 37.3%, Post Prandial Distress Syndrome (PDS) in 30.7%, and 32% had both EPS+PDS. 38% of the NUD patients were positive on Rapid Urease Test (RUT) suggesting H. pylori infection. 88.7% of NUD patients were IgA-tTG antibody negative and 11.3% serologically positive. The Duodenal biopsy was normal in 48% of patients, 21.3% had mild inflammation/duodenitis, 8% chronic duodenitis and 22.7% had various grades of Celiac Disease (as per Marsh Grading). These 22.7% showing evidence of Celiac Disease on histopathological examination showed Marsh Grade 1 in 12.7%, Grade-2 in 2%, Grade 3A in 6.7%, and Grade 3B in 1.3%. Only 17.6% of biopsy positive had IgA-tTG antibody positivity but only 4% of total cases were positive for both biopsy and IgA-tTG antibody (p-value 0.05). Eosinophilic infiltration in duodenum common in NUD patients. It was observed that 17.33% (26/150) NUD patients had duodenal eosinophilia. Further, look for the association of duodenal eosinophilia with various diseases. 33.33% (19/57) H. pylori patients had duodenal eosinophilia with p-value < 0.001. It was also observed that 7.52% (7/93) others like normal individual, Chronic duodenitis, mild inflammation/ duodenitis had Duodenal eosinophilia. CONCLUSION: The prevalence of H. pylori and IgA-tTG antibodies in non-ulcer dyspepsia patients was 38% and 11.3% respectively. The spectrum of Duodenum biopsy abnormalities in NUD patients included mild inflammation/ duodenitis, Chronic duodenitis, and Celiac Disease. 22.7% of NUD patients had various degrees of celiac disease morphology on D2 biopsy and only 17.6% of these biopsy positive patients were positive for IgA-tTG. Only 4% of total NUD patients were positive for both biopsy and IgA-tTG antibody labeled as Celiac Disease (CeD). There is a significant association between H. pylori and duodenal eosinophilia.
