Impaired gastric accommodation in patients with postprandial distress syndrome type of functional dyspepsia assessed by 2D ultrasonography.

BACKGROUND AND PURPOSE: The pathophysiology of postprandial distress syndrome includes impaired gastric accommodation, hypersensitivity to gastric distension and delayed gastric emptying. 2D-ultrasonography is one of the methods to assess gastric accommodation by measuring proximal gastric area and we evaluated its role in calculating proximal gastric area and thus assessing gastric accommodation in Indian patients with postprandial distress syndrome. METHODS: In a hospital-based comparative analysis, proximal gastric area was measured with 2D-ultrasonography of postprandial distress syndrome (PDS) patients and compared with healthy controls. Five readings were measured every five minutes till 25 minutes after 400 mL of vegetable soup. The Patient Assessment of Upper Gastrointestinal Disorders-Quality of Life (PAGI-QOL score) and diets aggravating PDS symptoms were studied through detailed questionnaires. Sample size was calculated at 80% study power and alpha error of 0.05 to be 30 subjects in each group. RESULTS: The mean age of patients (18 males) vs. 30 healthy controls (25 males) was 40.8 ± 11.50 years vs. 36.37 ± 7.58, respectively, (p = 0.084). Proximal gastric area was significantly lower in patients versus healthy controls at five minutes (22.54 ± 2.77 vs. 30.66 ± 2.55 cm2), 10 minutes (23.03 ± 2.45 vs. 31.10 ± 2.06 cm2), 15 minutes (23.06 ± 2.27 vs. 30.31 ± 2.11 cm2), 20 minutes (22.21 ± 2.31 vs. 29.73 ± 1.71 cm2) and 25 minutes (22.02 ± 2.33 vs. 28.39 ± 1.55 cm2); p < 0.001 at all intervals of time, indicating impaired gastric accommodation. The QOL was poor in all patients with PDS with mean PAGI-QOL score of 31.30 ± 15.05, median of 30, minimum score of 12 and maximum score of 66. CONCLUSIONS: Measurement of proximal gastric area with 2D-ultrasonography is simple and non-invasive. Proximal gastric area in patients was lower than controls, indicating impaired gastric accommodation. Poor quality of life was universal in patients with postprandial distress syndrome.

Histopathological and Immunohistochemical Findings in Congenital Pouch Colon: A Prospective Study.

BACKGROUND: There is a paucity of literature on the histopathological aspects of congenital pouch colon (CPC) and immunohistochemical (IHC) assessment has not been reported. So we planned to study the histopathological and IHC findings within the spectrum of CPC and compare the findings with the normal colon. METHODS: This is a descriptive prospective study on CPC patients. There were 49 cases of CPC (42 males and 7 females) and 13 controls. Histological examination was done using hematoxylin and eosin and Masson trichrome stain. IHC analysis was done with actin, myosin, and desmin antibodies, and neuron-specific enolase and S100 markers for counting ganglionic cells. RESULTS: Histologically, congestion, edema and hemorrhage were seen in mucosa, submucosa, and serosa. Muscle layers were disrupted and divided into bands. An additional muscle coat inside of the muscularis propria was seen in CPC types 1 and 2. Mature ganglionic cells were reduced and muscle layers showed reduced and patchy positivity for smooth muscle actin, myosin, and desmin compared to a normal colon. CONCLUSIONS: Histopathological and IHC findings suggest that CPC has distinct defects in the neuromusculature.

Cervical esophageal web and celiac disease.

BACKGROUND AND AIM: There is paucity of prospective data on association between cervical esophageal webs and celiac disease. It is not clear whether all patients with cervical esophageal web need screening for celiac disease. Hence, the present study was carried out to determine the association of cervical esophageal web with celiac disease. METHODS: This prospective study included consecutive patients with symptomatic cervical esophageal web diagnosed over a period of 4.5 years. Tissue transglutaminase antibody was measured in serum of each patient. Patients with elevated tissue transglutaminase antibody titer were subjected to esophagogastroduodenoscopy and biopsies were obtained from the descending duodenum to look for histological changes of celiac disease. Esophageal web was treated with bougie dilatation. Celiac disease was diagnosed on the basis of elevated tissue transglutaminase antibody and suggestive duodenal histology. RESULTS: Twenty one patients were diagnosed to have cervical esophageal web. Eighteen (85.7%) had evidence of iron deficiency. Five (23.8%) patients with cervical esophageal web fulfilled criteria for diagnosis of celiac disease. All five had evidence of iron deficiency. None of these patients gave a history of chronic diarrhea. All patients were treated with bougie dilatation. Patients with celiac disease were advised of a gluten-free diet. All five celiac disease patients are free of dysphagia without recurrence after a mean follow up of 10 months (range: 3 to 16 months). CONCLUSIONS: There is association between cervical esophageal web and celiac disease. All adult patients with cervical esophageal web and iron deficiency need screening for celiac disease even in the absence of chronic diarrhea.

Seroepidemiology and role of polymerase chain reaction to detect viremia in an epidemic of hepatitis E in Western India.

AIM: In an outbreak of hepatitis E affecting 859 individuals, we evaluated the titres of serological markers (IgM anti-HEV and IgG anti-HEV) and hepatitis E virus (HEV) RNA by reverse transcriptase polymerase chain reaction. METHODS: Serological markers for acute hepatitis were evaluated in 294 icteric patients (Group A) and 300 apparently healthy controls (Group B). HEV RNA was measured by RT nPCR in 19 patients in the first week of illness in patients with negative IgM anti-HEV. FINDINGS: None of the patients were positive for hepatitis A or B. In Group A, IgM anti-HEV was positive in 80.2%, 71.4% and 26.8% and IgG anti-HEV was positive in 58.3%, 77.1% and 86% of patients who were in their first, second and third weeks of illness, respectively. In Group A, amongst the 19 IgM anti-HEV negative patients in their first week of illness, 16 were positive for HEV RNA. In Group B 63.6% cases were positive for IgM anti-HEV. In the same village there had been a similar epidemic 4 years ago; none of the 93 patients traced from that time developed acute hepatitis during the present epidemic and all demonstrated the presence of IgG anti-HEV. This suggests that IgG anti-HEV was perhaps protective. CONCLUSION: During the first week of illness patients may display HEV viremia while testing negative for IgM and IgG anti-HEV. The presence of IgG anti-HEV may play a protective role against HEV infection and in the absence of IgM may help in diagnosing acute hepatitis E. Over 3 weeks of illness the IgM anti-HEV titres fall progressively whilst IgG anti-HEV titres gradually rise.
