“…Furthermore, a prevalence of 64.6% in children with risk factors of overcrowding, patronizing of food vendors, and illiteracy was reported in Egypt [36]. In the Republic of Benin, a 71.5% prevalence rate was reported but was not associated with age, sex, marital status, religion, occupation, or education [37]; 73.2% in Cameroon with a significant association with age, socioeconomic status, alcohol, family history, and nonsteroidal anti-inflammatory drugs and similarly anemia, duodenal ulcer, and chronic gastritis have been reported as common in patients with H. pylori infection [38]; and 71.43% prevalence rate was published in Algeria [39]. In a research conducted in Ethiopia, 88.9% H. pylori prevalence was reported in male individuals, while 82.8% was in female individuals [40].…”

“…In Algeria, Moubri et al [62] in a study used both invasive and noninvasive methods including 13 C UBT, monoclonal SAT (HpStAR), endoscopy, RUT, histology, and culture for the diagnosis of HPI in children. In another epidemiological study of HPI in symptomatic patients in a tertiary hospital in Algeria, Kasmi et al [39] reported only the use of endoscopy and histological examination of biopsies in the diagnosis of HPI, for which a prevalence rate of 66.12% was recorded. In Egypt, another North African country, a consensus reached by experts in 2017 on the diagnosis of HPI in the country recommended the use of SAT, which is widely available in Egypt; histological detection of H. pylori; and assessment of atrophy; RUT; and UBT.…”

Background: The burden of Helicobacter pylori infection (HPI) in Africa remains high with varying levels of prevalence among children and adults reported in different regions of the continent. Persistent and uneradicated HPI could result in gastric cancer, although less severe pathological outcomes have been reported among Africans – the so-called “African enigma.” Summary: Analysis of endoscopic findings of the upper gastrointestinal tract demonstrates similarities with that of patients from the West. Thus, it could be asserted that the true picture of HPI in Africa is yet to be unveiled due to several challenges including inadequate health-care system, lack of treatment guidelines and standardized protocol for diagnosis, and lack of data. This review explores the prevalence, diagnosis, treatment, and health-care system in Africa as it relates to HPI, thus providing an update and highlighting the need for an African HPI guideline. Key Messages: There is high prevalence of Helicobacter pylori infection (HPI) in Africa with an increasing burden of antibiotic resistance. Various methods including invasive and noninvasive methods are deployed in the diagnosis of HPI in Africa. There is a need for consensus on diagnosis and treatment of HPI in Africa.

Helicobacter Pylori - From First Isolation to 2021

Infection due to Helicobacter pylori is a public health challenge worldwide as over 3 billion persons are infected with the bacterium globally. There is a serious need to update the knowledge on the epidemiology of this bacterial pathogen and its probable risks factors to generate intervention programs that will reduce the morbidity and mortality of infected individuals. This chapter evaluated the seromarkers of H. pylori infection and its predisposing factors among students of Nasarawa State University, Keffi, Central Nigeria. This study was done between June through August 2019; blood and stool specimens were collected from 400 students of the institution. Before the commencement of the study, ethical clearance and informed consent were retrieved and a structured questionnaire was administered to each participant. Specimens were screened for H. pylori antigen and antibody using rapid test kits (CTK Biotech, Inc., San Diego, USA and Biotest Biotech, China). Information obtained were analyzed using SSP version 2.80. P values <0.05 were reflected statistically significant. Out of the 400 students tested, 166 (41.5%) and 128 (32.0%) showed positive for anti-H. pylori IgG and Ag markers respectively. The antibody seromarker was higher in female while the H. pylori antigen was higher in males. Those students aged 21–30 years old reported the highest prevalence of the seromarkers while those of more than 41 years old had the least prevalence. Location, type of toilet facility and place of residence were statistical associated between H. pylori antigen (P < 0.05). There was a statistically significant association between anti-H. pylori IgG and the sources of water of the students (P < 0.05). This is the first public report that has successfully reported the prevalence of these seromarkers among students of a tertiary institution in Nasarawa state. The overall outcomes of this study stressed the need for student-based intervention programs to stem the transmission of this infection in Nasarawa State, Nigeria.

“…For example, most of the studies in Libia relied on serological tests for diagnosing H. pylori infection [ 68 , 69 , 70 ]. Nevertheless, in areas like Algeria, Tunisia, West, East, or Central Africa, studies also reported the use of more accurate methods such as a urea breath test, stool antigen, rapid urease test, or histological exam based on upper digestive endoscopy collected gastric biopsies and their combination [ 79 , 80 , 81 ]. Moreover, the use of certain diagnostic methods may be limited in Africa by poor health infrastructure, poor standard of living, and the limited number of health-care professionals [ 79 ].…”

Worldwide Prevalence and Risk Factors of Helicobacter pylori Infection in Children

2022

View full text Add to dashboard Cite

Helicobacter pylori is usually acquired during childhood. The reports from the last two decades pointed out a decrease in H. pylori prevalence across geographical areas worldwide compared to previously reported data. Most of the studies performed in America found an overall H. pylori infection prevalence of approximately 50%. The most important risk factors in America include being male, poor adherence or difficult access to treatment, and the lack of in-home water service. Despite the descending trend in prevalence worldwide, the overall prevalence in Africa remains very high (70%). Nevertheless, the prevalence of H. pylori in children without gastrointestinal who underwent screening was reported to be only 14.2%. The main risk factors in Africa are having a traditional pit or no toilet, poverty, birth order, source of drinking water, or being a farmer. Asia seems to have the widest variations in terms of H. pylori prevalence. Several risk factors were reported in Asia to be associated with this infection, such as lower income and educational level, house crowding, rural residence, ethnicity, the use of tanks as water supplies, alcohol drinking, active smoking, eating spicy food or raw uncooked vegetables, poor living conditions and sanitation. The overall prevalence of H. pylori infection in European children is almost 25%. Portugal has the highest prevalence of all European countries at 66.2% in children 13 years of age. The risk factors in European individuals consist of living in rural areas, eating unwashed fruits and vegetables, not washing hands after school, low parental education and unemployment, and short education duration. Further studies are required to identify the precise mechanisms involved in the discrepancies of H. pylori prevalence worldwide.
