[Food patterns in Russian patients with gastroesophageal reflux disease: the results of pilot comparative study].

AIM: To evaluate nutritional patterns in patients with gastroesophageal reflux disease (GERD) compared to the control group without GERD. MATERIALS AND METHODS: The data of complex examination of patients referred to perform esophageal pH-impedance recording and who gave written informed consent to participate in the study served as a source data. All the participants underwent complex examination, including clinical data (presence of heartburn and acid regurgitation), symptom evaluation (GERD-Q questionnaire), esophagogastroscopy, esophageal pH-impedance recordings and food frequency questionnaire. Diagnosis of GERD was based on GERD-Q score 8, acid exposure time 6%, number of gastroesophageal refluxes 80/day by 24-hrs esophageal pH-impedance recordings. Nutritional patterns were assessed with the use of healthy eating pyramid principles. RESULTS: Overall 165 patients were enrolled and the data of 150 of them (34 with confirmed GERD and 116 of the control group) were available for the final analysis. The patients of the both groups consumed lower compared to the recommended amounts of dairy and higher amounts of meat. Those with GERD consumed larger amounts of fruits (0.910.68 compared to the values of healthy eating pyramid vs 0.520.57 in the control group, p=0.001), and fats (0.690.55 vs 0.490.55, p=0.001). Compared to the controls, patients with GERD consumed lower amounts of vegetables (0.860.46 of the healthy eating pyramid vs 0.940.63 in the control group, р=0.004) and sugars confectionaries (0.380.39 vs 1.930.98, p=0.0001). CONCLUSION: Nutritional patterns of patients with gastroesophageal reflux disease significantly differ compared to the control group. The obtained data may be used for diet modification in patients with arterial hypertension.

[Association of nutritional patterns and arterial hypertension in Russia: does it exist?]

AIM: To evaluate nutritional patterns in patient with arterial hypertension (AH) compared to the control group without elevated blood pressure. MATERIALS AND METHODS: Retrospective search for unique records of the patients aged 1875 y.o. with complete data on usual nutrition with food frequency methods who had no mentions of diabetes mellitus, food intolerance or allergies, and history of major abdominal surgery, as well as signs of secondary reasons of AH. Nutritional patterns were assessed with the use of healthy eating pyramid principles. Ststistical analysis was performed with the use of SPSS 13.0 for Windows software (SPSS Inc., USA). RESULTS: The data of 711 patients were available for the final analysis (595 of them in AH group). Both groups consumed lower compared to the recommended amounts of fruits, dairy and higher amounts of meat. Those with AH consumed larger amounts of vegetables (1.130.74 compared to the values of healthy eating pyramid vs 0.940.63 in the control group; p=0.004), fruits (0.800.66 vs 0.520.57; p=0.001), meat (1.851.05 vs 1.620.91; p=0.002) and fats (0.770.60 vs 0.490.55; p=0.001). On the other hand, there were lower rates of consumption of sugars, and confectionaries in the structure of nutritional patterns in patients with AH compared to the control group: (0.350.44 of the healthy eating pyramid in AH vs 1.930.98, in the control group; p=0.0001). CONCLUSION: Nutritional patterns of patients with arterial hypertension significantly differ compared to the control group. The obtained data may be used for diet modification in patients with arterial hypertension.

[Association of thermal food processing methods and small intestinal bacterial overgrowth syndrome].

Small intestinal bacterial overgrowth (SIBO) is a widespread disease which antibiotic therapy is not effective enough and the relapse rate is high. Microbiota is dependent on dietary pattern of the patient and specific nutrients, therefore the diversity of dietary patterns may be one of the major factor promoting SIBO or its relapses after treatment. The aim: to compare the patterns of thermal food processing methods in patients with and without SIBO. Material and methods. We performed retrospective single center database search to identify unique depersonalized records of patients with SIBO and the data of lactulose breath test and nutritional assessment with the use of 24-hours dietary recall. Inclusion criteria were complete data on patient's demography, adequate data of nutritional assessment and the lactulose breath test, absence of previous history of SIBO treatment in a special form of the database. In accordance with the results of lactulose breath test, patients were assigned into groups with the presence of SIBO with excess production of hydrogen (H2), methane (CH4), both gases (CH4-H2) or without SIBO (control group). According to the data of 24 h dietary recall, we divided all dishes and products consumed by a patient to 6 categories (Cat) depending on thermal food processing method: those that were not processed (raw) (Cat-r), boiled (Cat-bl), fried (Cat-f), stewed (Cat-s), baked in the oven (Cat-bk) or grilled (Cat-g). To analyze the structure of thermal food processing, we divided the weight of all products or dishes that underwent specific method of processing to the total weight of the food eaten. We did not take into the account the weight of thermally stable components like water and salt. The pattern of thermal food processing within each patients group was obtained as a quotient of the total percentage (by weight) of the food processed with the certain method by the number of patients in the group. Results and discussion. The data of 1108 patients were available for the final analysis: 602 patients in the SIBO-H2 group, 140 in the SIBO-CH4 group, 248 in the SIBO-CH4-H2 group, and 118 patients in the control group. The distribution of thermal food processing categories was in patients with SIBO-H2 as follows: Cat-r - 45.8±17.3%, Cat-bl - 31.9±15.7%, Cat-s - 3.5±7.7%, Cat-f - 6.3±10.4%, Cat-bk - 12.2±10.2%, Cat-g - 0.3±3.3%); in patients with SIBO-CH4: Cat-r - 47.9±17.4%, Cat-bl - 29.6±15.6%, Cat-s - 4.4±7.6%, Cat-f - 5.8±9.8%, Cat-bk - 12.3±10.4%, Cat-g - 0,2±2,7%; in patients with SIBO-CH4-H2: Cat-r - 45.6±16.3%, Catbl - 31.5±16.2%, Cat-s - 4.0±8.0%, Cat-f - 5.1±9.3%, Cat-bk - 13.4±10.8%, Cat-g - 0.4±2.3%. Similar results were obtained in the control group (Cat-r - 44.7±17.0%, Cat-bl - 32.6±16.5%, Cat-s - 2.7±6.0%, Cat-f - 5.5±8.0%, Cat-bk - 14.2±10.6%, Cat-g - 0.3±2.0%). There were no significant differences between the SIBO and control groups by mean percentage of raw, boiled, stewed, fried, baked and grilled food intake. Conclusion. We found no association between thermal food processing patterns and SIBO. It seems that thermal food processing patterns has no influence on SIBO and its variants.
