The mortality rate related to H pylori infection is not precisely known, but it seems to be minimal (ie, approximately 2%-4% of all infected people). Mortality is due to the complications of the infection, such as gastric ulcer perforation or MALTomas of the GI tract. Otherwise, the morbidity of H pylori infection can be very high.

What happens after exposure to CAGA?

After the exposure to CAGA -positive H pylori strains, an increase in catalase, glutathione peroxidase, and superoxide dismutase activity has been reported. This increase is associated with fewer DNA adducts and reduced susceptibility of the gastric cells to the irreversible injuries from reactive oxygen species (ROS) compared with exposure to CAGA -negative H pylori strains. Such alterations of the ROS scavenging enzymes may partly account for the increased risk of gastric cancer in individuals with H pylori infection.

H. pyloriis associated with the development of gastrointestinal disorders as chronic gastritis, peptic ulcer, and gastric adenocarcinoma (Kuipers 1997). H. pyloriis also involved in the development of other extra-gastric disorders such as mucosa-associated lymphoid tissue lymphoma (MALT), idiopathic thrombocytopenic purpura, vitamin B12deficiency, and iron deficiency (Kuipers 1997). Eradication of H. pyloricould help in the management of these H. pylori-associated disorders.

What is a probiotic?

Probiotics are defined as living microbial species that can include anti-inflammatory and anti-oxidative mechanisms that may improve bowel microecology and general health (Lu et al. 2016). Probiotics are live microorganisms, which when administered in adequate amounts confer a health benefit on the host.

How high is the prevalence of H. pyloriresistance to clarithromycin?

In a recent systematic review, the global incidence of primary H. pyloriresistance to clarithromycin has been reported to be as high as 17.2%, showing an increase worldwide (Kuipers 1997). The prevalence of H. pyloriresistance to clarithromycin varies among different countries, such as 10.6 to 25% in North America, 16% in Japan, and 1.7 to 23.4% in Europe (Elitsur et al. 2006; Horiki et al. 2012; Koletzko et al. 2006). This disparity in resistance rates seems to be correlated to the national level of macrolide consumption and different policies for antibiotic consumption in different countries (Agudo et al. 2010a, b), for example, 49% of clarithromycin resistance has been reported in some Spanish areas, but only 1% in the Netherlands, reflecting a stricter Northern European policy for antibiotic use than in Southern European countries (Seck et al. 2013). New macrolides were marketed in Europe at the beginning of the 90’s; patients were exposed to macrolides in order to treat respiratory infections with antibiotics of this group. Additional aspects such as geographic features, virulence factors of H. pyloristrains, or some host aspects [age, place of birth] could contribute to the significant variation in the prevalence of antibiotic resistance (Van Doorn et al. 2000).

What should be taken into account before establishing a treatment plan for the patient to avoid repeated treatments?

Information about local resistant to antibiotics should be taken into account before establishing a treatment plan for the patient to avoid repeated treatments. Several expositions to antibiotic treatments could result in more side effects and a decrease in the percentage of antibiotic resistance.

Why is amoxicillin administered first?

Amoxicillin is administrated first, due to the fact that amoxicillin disrupts the bacterial cell walls to prevent the development of efflux channels transferring the rest of the antibiotics out of bacteria (Webber and Piddock 2003). There were some studies published, the majority of them in Italy, where the result of sequential therapy was superior to normal standard triple therapy. More recent data from studies developed in South America and Asia shows eradication rates lower than 80% (Kuipers 1997).
