Introduction In pernicious anemia besides the presence of megaloblasts in the bone marrow, changes in myeloid series were seen; being the most evident among the metamyelocyte. The aim of this study was to perform the quantification of metamyelocyte of the bone marrow in pernicious anemia. Material and methods Between 2000-2006 in the Clinic of Hematology-Nis, 68 patients with pernicious anemia were examined and 30 with dyspeptic syndrome (control group). The group of patients with pernicious anemia in relation to pathohistologic changes of gastric mucosa was divided into three sub-groups. Morphometrical analysis of metamyelocyte of the bone marrow was carried out by the application of the double netlike system (B100). The following parameters were used: relative surface, contour length, absolute surface of nucleus and cytoplasm, absolute contour nucleus and cytoplasm density, shaped nucleus and cytoplasmic factor and nuclear-cytoplasmatic ratio of meta- myelocytes. Results Relative surface, contour length, absolute surface and contour density of nucleus and cytoplasm of metamyelocytes increased simultaneously with the degree of atrophic gastritis. Shaped nucleus and cytoplasmic factor and nuclear-cytoplasmatic ratio of metamyelocytes decreased in all examined groups in relation to the control group. Conclusion Not only are bone marrow erythroid elements scoped with megaloblastic changes but the changes on the level of leukocyte cells as well. The result of this is the phenomena of giant metamyelocytes.

Background: The purpose of the study was to see whether chronic alcohol abuse had any effect on the gastric mucosa in a population already affected by a high prevalence of Helicobacter pylori.Methods: 35 males with a history of chronic alcohol abuse were compared with 35 males who were abstinent or social drinkers. All subjects had complaints of dyspepsia. All subjects underwent endoscopy and targeted biopsies were taken from three specific sites in the stomach, namely body, antrum and incisura. Biopsies were studied to look for changes of atrophic gastritis and intestinal metaplasia. The presence or absences of H. pylori on the tissue biopsy were also recorded.Results: Atrophic gastritis were only assessable in 24 alcoholic patients and 21 non-alcoholic patients due to the inadequacy of the depth of the biopsy. AG were found to be equally distributed in both the groups. 23 (64.9%) patients in the alcoholic group and 19(54.5%) in the control group had AG (OR-1.54, p=0.47). Intestinal metaplasia was seen in 10 (28.5%) alcoholic group and 12 (34.2) in the control group (OR-0.65, p=0.45). Of the 42 subjects detected to have AG, 16 (38.1%) had IM. However, IM were always associated with AG. In addition, H. pylori were not seen to be different in the two groups. H. pylori were positive in 18 (51.4%) alcoholic and14 (40%) non-alcoholic patients (p=0.33).Conclusions: Chronic alcohol abuse doesn’t appear to have any major impact on the gastric mucosa in terms of producing premalignant lesions such as atrophic gastritis or intestinal metaplasia or enhancing the prevalence of H. pylori.

The condition of gastric mucosa was assessed in relatives of patients with gastric cancer (RPGC). The study included 108 RPGC (main group) and 102 patients with no family history of gastric cancer who were screened for dyspepsia. All study participants were subjected to clinical examination, questioning and esophagogastroduodenoscopy (EGDS) with a biopsy, in which the gastric mucosa state was assessed according to the modified Sydney system, the OLGA and OLGIM systems, and the definition of Helicobacter pylori (H. pylori) infection. It was established that the prevalence of H. pylori infection in the main group was 58.3 % (95 % CI 48.8–67.7), in the control group – 56.0 % (95 % CI 46.1–65.6). At RPGC, atrophy of any localization (46.3 % (95 % CI 39.4–53.2) versus 26.5 % (95 % CI 20.4–32.6), respectively, was found more often than in the control group, respectively, p = 0.002), antral atrophic gastritis (41.6 % (95 % CI 34.8–48.4) versus 26.5 % (95 % CI 20.4–32.6), respectively, p = 0.020), and isolated atrophy in the stomach body (4.6 % (95 % CI 1.7–7.4) versus 0 % ( p = 0.03). In RPGC, atrophy developed at a younger age (48.0 years (95 % CI 44.0–52.0) versus 53.0 years in the control group (95 % CI 48.3–57.8) p = 0.000). There were no significant differences between the groups in the incidence of metaplasia and dysplasia. The following risk factors for development of atrophy were identified in the factor analysis: age over 6f0 years (odd ratio (OR) 53.0; 95 % CI 12.2–390.1; p < 0.001), age over 40 years (OR 4.0; 95 % CI 2.0–8.2; p < 0.001), heredity burdened by gastric cancer (OR 2.7; 95 % CI 1.4–5.7; p = 0.006) and the use of strong alcoholic beverages (OR 5.5; 95 % CI 1.6–21.6; p = 0.009). The frequency of the atrophy development of the gastric mucosa is increased in RPGC, and atrophic gastritis develops at a younger age in comparison with individuals without a burdened hereditary history. In addition to the hereditary factor, the risk of atrophy is associated with age and alcohol use.

Serum levels of somatostatin were determined by RIA method in 50 patients with liver cirrhosis, 15 with pernicious anemia and atrophic gastritis, 31 with inflamatory bowel disease, 32 with colorectal tumors and in 40 control persons. In patients with liver cirrhosis somatostatin levels were significantly higher than in control group (p<0.01). Patients with pernicious anemia and ulcerative colitis in acute phase of the disease had significantly lower levels of somatostatin (p<0.01) (p<0.005). In patients with colorectal tumors somatostatin were significantly lower then in control group (p<0.01). Our results show that the liver is involved in somatostatin metabolism. Atrophic gastritis, ulcerative colitis and M. Crohn, so as colorectal neoplasia were associated with significantly changes in somatostatin levels which suggest the potential pathophysiologic and terapeutic role of somatostatin in those disease.

The aim: To determine the effect of prolonged use of H2-histamine receptor blockers on the degree of contamination of the gastric mucosa with HP infection in patients with chronic non-atrophic gastritis. Materials and methods: 28 patients with chronic atrophic gastritis (the main group), who regularly took H2-histamine receptor blockers for 2 to 7 years, and 30 patients (control group), who never used them were comprehensively examined. Comprehensive examination included: step-by-step intragastric pH-metry, esophagogastroduodenoscopy, helicobacter infection test (НР) (helicobacter urease test and microscopic examination of stained smears), histological investigations of the gastric stump mucous, material for which was taken during endoscopy from 4 topographical zones: from the middle third of the gastric antrum and body of stomach on the big and small curvature. Results: All the patients in 100% of cases have confirmed the existence of chronic non-atrophic gastritis in both active and inactive stages of varying degrees of severity. Helicobacter infection was detected in 100% of cases. A comparative analysis of the data on the average degree of infection of the gastric mucosa by HP infection in the same topographic zones in the patients of the main and control groups revealed a significant (p <0.05) higher degree of seeding of the gastric mucosa in patients of the main group in all zones. Conclusions: Monotherapy for chronic non-atrophic gastritis with blockers of Н2-histamine receptors leads to an increase in the degree of gastric mucosa semination with HP infection. This fact requires mandatory parallel use of antibacterial agents – colloidal bismuth subcitrate and antibiotics, with blockers of Н2-histamine receptors.

The aim: To determine of the factors influencing the formation of “kissing” duodenal bulb ulcer in patients with chronic non-atrophic gastritis. Materials and methods: The data of a comprehensive examination of 34 patients with chronic non-atrophic gastritis were analyzed, in which the examination revealed “kissing” ulcers of the duodenal bulb (primary group), and 37 patients with chronic non-atrophic gastritis, in which single ulcers were detected in the bulb (control group). Comprehensive examination included: step-by-step intragastric pH-metry, esophagogastroduodenoscopy, helicobacter infection test (НР) (helicobacter urease test and microscopic examination of stained smears), histological investigations of the gastric stump mucous, material for which was taken during endoscopy from 4 topographical zones: from the middle third of the gastric antrum and body of stomach on the big and small curvature. Results: In the course of the examination, the presence of chronic non-atrophic gastritis in 100% of cases was confirmed with a different degree of activity of the inflammatory process on the gastric mucosa, as well as the presence of Helicobacter pylori infection with a high degree of colonization of the gastric mucosa in the absence of a significant difference (p> 0.05) in the stomach zones. It was found that the main difference that can be traced in 100% of cases is the difference in the anatomical structure of the bulb of the duodenum, namely, the shape: in the control group, the shape and lumen of the duodenal bulb are round, while in the patients of the main group the bulb the duodenum, starting from the pylorus, is stretched toward the large and small curvature, which gives the lumen bulb its oval shape. Conclusions: “Kissing” ulcers of the duodenal bulb are formed in patients with chronic non-atrophic gastritis only if the patients have a peculiar anatomical structure of the bulb, in which the lumen has an oval shape.

Background/Aim. Autoimmune atrophic fundic gastritis induces the pernicious anemia (PA), as well as the changes in both epithelium and endocrine cells of gastric mucosa. The most important complications are: achlorhydria, hypergastrinemia, gastric cancer and enterochromaffin-like ( ECL) carcinoid. The aim of this study was to examine ECL carcinoid histogenesis in A-gastritis associated with PA. Methods. During the period from 2000?2006, 65 patients with PA and 30 patients of the control group were examined. Histopathological examination was done in endoscopical biopsies of gastric mucosa fixed in 10% formaldehyde. Paraffin sections were stained with classic hematoxylin-eosin (HE); histochemical AB-PAS (pH 2.5), cytochemical argyrophilic Servier-Munger?s and immunocytochemical PAP methods for G cell identification and chromogranin A antibodies - specific marker for neuroendocrine ECL cells. Both G and ECL cells were counted per 20 fields, of surface 0.0245312 mm2 by a field. Basal gastrin serum levels were also examined by using radioimmunoassay (RIA) method. The obtained results were statisticaly calculated by using Student?s t test. Results. Marked antral G cell hyperplasia associated with corporal ECL hyperplasia was found. ECL cell hyperplasia was of simplex, linear, adenomatoid type to the pattern of intramucous ECL cell carcinoid. An average number of G cells was statistically significant in the patients with PA as compared to the control group (p < 0.05) as well as an average number of ECL cells. Conclusion. We concluded that antral G cell hyperplasia accompanied by gastrinemia induces ECL hyperplasia and ECL corporal carcinoid in A-gastritis and that their histogenesis develops trough simple, linear and adenomatoide hyperplasia. .

Background & Aims: Previous genome-wide association studies showed that genetic polymorphisms in toll-like receptor 1 (TLR1) and protein kinase AMP-activated alpha 1 catalytic subunit (PRKAA1) genes were associated with gastric cancer (GC) or increased Helicobacter pylori (H. pylori) infection susceptibility. The aim of this study was to evaluate the association between TLR1 and PRKAA1 genes polymorphisms and H.pylori infection, atrophic gastritis (AG) or GC in the European population.Methods: Single-nucleotide polymorphisms (SNPs) were analysed in 511 controls, 340 AG patients and 327 GC patients. TLR1 C>T (rs4833095) and PRKAA1 C>T (rs13361707) were genotyped by the real-time polymerase chain reaction. H. pylori status was determined by testing for anti-H. pylori IgG antibodies in the serum.Results: The study included 697 (59.2%) H. pylori positive and 481 (40.8%) H. pylori negative cases. We observed similar distribution of TLR1 and PRKAA1 alleles and genotypes in H. pylori positive and negative cases. TLR1 and PRKAA1 SNPs were not linked with the risk of AG. TC genotype of TLR1 gene was more prevalent in GC patients compared to the control group (29.7% and 22.3% respectively, p=0.002). Carriers of TC genotype had a higher risk of GC (aOR=1.89, 95% CI: 1.26–2.83, p=0.002). A similar association was observed in a dominant inheritance model for TLR1 gene SNP, where comparison of CC+TC vs. TT genotypes showed an increased risk of GC (aOR=1.86, 95% CI: 1.26–2.75, p=0.002). No association between genetic polymorphism in PRKAA1 gene and GC was observed.Conclusions: TLR1 rs4833095 SNP was associated with an increased risk of GC in a European population, while PRKAA1 rs13361707 genetic variant was not linked with GC. Both genetic polymorphisms were not associated with H. pylori infection susceptibility or the risk of AG.

Pan masala is commonly consumed in south-east Asian and other oriental countries as an alternate of tobacco chewing and smoking. Genotoxic potential of pan masala (pan masala plain and pan masala with tobacco known as gutkha) was evaluated employing chromosome aberration (CA) and micronucleus (MN) assay in vivo. Animals were exposed to three different doses (0.5%, 1.5% and 3%) of pan masala plain (PMP) and gutkha (PMT) through feed for a period of 6 months and micronucleus and chromosomal aberrations were studied in the bone marrow cells. Induction of mean micronuclei in polychromatic erythrocytes (MNPCE) and normochromatic erythrocyte (MNNCE) was higher in both types of pan masala treated groups with respect to control group. Both pan masala plain and gutkha treatment significantly induced the frequency of MNPCE and MNNCE in the bone marrow cells, indicating the genotoxic potential. Furthermore, slight decline in the ratio of polychromatic erythrocytes to normochromatic erythrocytes was also noticed, suggesting the cytotoxic potential even though the ratio was statistically non significant. A dose-dependent, significant increase in chromosome aberration was observed in both types of pan masala treated mice with respect to control. However, no significant difference in micronucleus and chromosomal aberration induction was noticed between two types of pan masala exposed (PMP and PMT) groups. Results suggest that both types of pan masala, i.e. plain and gutkha, have genotoxic potential.
