Helicobacter pylori infection in 755 patients with digestive complaints: Pasteur Institute, Morocco, 1998-2007

Abstract

We determined the prevalence of Helicobacter pylori infection in 755 patients with digestive complaints identified from laboratory records at the Pasteur Institute, Morocco from 1998 to 2007. Epidemiological factors and gastrointestinal conditions associated with this infection were also studied. All patients underwent endoscopy and diagnosis was by histology examination. The prevalence of H. pylori infection was 69%. The difference in prevalence between the age group 40-50 years and other age groups was statistically significant; gender had no significant association. H. pylori infection was found in 92% of chronic gastritis cases. The prevalence of H. pylori was significantly higher in the antrum (73%) than in the corpus (21%) and the pylorus (6%).

Epidemiological Profile of Helicobacter pylori Infection in Patients with Digestive Symptoms in Algeria

“…pylori in 71.73% of our population. The same results were found by Attaf et al [ 36 ] which attributed 70.9% of lesions to this site, and Joutei et al [ 32 ] with 73%. In another study, these values remain higher than those reported by Binan et al [ 37 ] who attributed 40.0% of H .…”

“…pylori infection by age, we obtained a peak rate (71.43%) affecting the ‘60–69’ age group. This average is higher than those found by Joutei et al [ 32 ], which revealed a rate of 11% among subjects in the ‘60–70’ age groups. For Ivorian, no significant difference has been reported for age groups [ 33 ].…”

Epidemiology of Helicobacter pylori Infection and Public Health Implications

“…Four studies were reported from Africa [16–19]. Studies from Africa recorded high H. pylori prevalence rates ranging from 41.3% to 91.3% [16–19].…”

“…Four studies were reported from Africa [16–19]. Studies from Africa recorded high H. pylori prevalence rates ranging from 41.3% to 91.3% [16–19]. There were seven studies that reported H. pylori prevalence from South America [20–26].…”

Prévalence de l’infection à Helicobacter pylori au cours de l’anémie par carence en vitamine B12 à Marrakech (Maroc)

“…L'HP induit une gastrite atrophique entraînant la destruction des cellules pariétales qui produisent le facteur intrinsèque. L'infection à HP est plus élevée dans les pays en voie de développement (78 % en Algérie, 71 % au Maroc, 69 % en Côte d'Ivoire) [11], il est logique de penser que la carence en vitamine B12 et ses conséquences soient plus importantes. La gastrite atrophique à HP est une cause fréquente du syndrome de non-dissociation de la vitamine B12 [10].…”
