Prevalence of Helicobacter Pylori Infection among Adult Patients with Different Gastrointestinal Parasites in Tanta City District

This work aims to estimate the prevalence of Helicobacter pylori ureA gene and evaluate cagA gene-positive strains in both patients of laryngeal squamous cell carcinoma (LSCC) and those with benign laryngeal polyps. This study included 49 patients confirmed pathologically to have LSCC and 15 patients with benign laryngeal polyps over a period from June 2013 to March 2015. Samples of laryngeal tissue were collected during direct laryngoscope under general anesthesia to be pathologically evaluated followed by analysis for H. pylori detection. Each laryngeal tissue sample was divided into three parts; one for bacteriological examination, the second for pathological examination and the third for PCR to detect both ureA and cagA genes. Out of 49 LSCC samples, 31 (64.6 %) was positive for ureA by PCR. Out of them, 29 samples (93.5 %) were cagA positive. Only three cases (20 %) of the benign laryngeal polyp were ureA positive by PCR and one of them was cagA positive by PCR. By the bacteriological culture, only eight samples (25.8 %) gave growth. All of them were ureA positive and only seven of them were cagA positive. There was a significant association between presence of H. pylori and LSCC as compared to benign laryngeal polyp which may contribute in the pathogenesis of laryngeal carcinoma. These results should be confirmed by further studies over larger number of cases.

Helicobacter pylori and enteric parasites co-infection among diarrheic and non-diarrheic Egyptian children: seasonality, estimated risks, and predictive factors

Helicobacter pylori (H. pylori) and intestinal parasites are known for their high prevalence in children. Both of them infect the gastrointestinal tract with overlapping clinical pictures. This study was conducted to determine H. pylori prevalence and its association with intestinal parasites in children, moreover to estimate risk and predictive factors for their detection in stool samples. Single fecal samples were collected from 226 Egyptian pediatric patients (125 diarrheic and 101 non-diarrheic) attending gastroenterology outpatients' clinics, from February 2016 to June 2017. All stool specimens were microscopically examined to search for ova and parasites. Copro-DNAs detection of H. pylori and Cryptosporidium were performed using nested-PCR assays. H. pylori was detected molecularly in 36.8% of the total study population, with a higher prevalence in diarrheic than in nondiarrheic children. Intestinal parasites were detected in 27.4% of the total study populations, of these, 43.9% had co-existence with H. pylori colonized patients and was significantly associated with Cryptosporidium spp. and G. intestinalis. Estimated risk of the presence of H. pylori was in January. Our data provide a better understanding of the epidemiology of H. pylori infection when associated with intestinal parasites. H. pylori co-existence with G. intestinals and Cryptosporidium may suggest the association of H. pylori infection with markers of fecal exposure. Whether H. pylori provides favorable conditions for intestinal parasitosis or vice versa, still further investigations are needed with an emphasis upon determining correlation with gut microbiomes.
