Indications and diagnostic tests for Helicobacter pylori infection. Recurrence of H. Recrudescence reflects the reappearance of the original strain of H. Instead, true reinfection occurs when, after successful eradication, a patient becomes infected with either the original strain or a new strain of H. Many investigators have found that recurrence rates during the first months after cure are due to late recrudescence. A documented H. It seems that low-efficacy therapy does not actually cure H.
Pylori reinfection after successful eradication is an important problem in the management of this disease. Recrudescence rather than reinfection is likely to be responsible for most recurrent cases because the recurrences decrease with time, declining sharply after the first year, and identified strains before and after therapy are usually genetically identical.
Intrafamilial transmission could be also involved in the reinfection of H. The reinfection rate after eradication therapy for H. The annual reinfection rates reported by Zendehdel et al. In contrast to the low rates of H. Therefore the high prevalence of H. Genetic factors may also play a role, susceptible individuals who have eradicated H. Several articles dealing with the occupational risk of infection by H. Pylori have been published. Matysiak-Budnik 35 showed an association between occupational exposure and an increased risk of infection.
Williams 36 , too, stated that there were increased occupational risks for endoscopy personnel. The prevalence of H. Intrafamilial transmission is a modality of infection and reinfection, which should never be forgotten. The close contact among family members appears to be a key route responsible for the transmission of H.
Therefore, all family members of infected people should always be screened, regardless of their symptoms. In this way, by reducing the undiagnosed patients, the risk of development of the H.
Its recurrence in the first year after eradication therapy is likely due to a mixture of recrudescence of infection and reinfection. The reinfection is predominant in the subsequent years after eradication while the risk of recurrence tends to decrease. Since the early age at acquisition of H.
Then, to optimize eradication rate of H. National Center for Biotechnology Information , U. Journal List Acta Biomed v. Acta Biomed. Author information Copyright and License information Disclaimer.

Gastro-Oral Transmission H. Oral-Oral Transmission The saliva is another possible source of H. Fecal-Oral Transmission H.
Transmission by water The exact way by which H. Transmission by Food As it happens with water, food products may also be contaminated while being handled under poor hygienic conditions. For Vietnamese people, using chopsticks to pick food into their mouths and take them to everyone, drinking from the same glass of water has a very high risk of H. With more than 30 years of experience in endoscopic testing and treatment, Dr. The doctor said that in the case of patients suffering from peptic ulcer disease, H.
Infection with H. In particular, the most common route of infection is the oral route, the level of infection often infected across all ages, excluding men, women, and children. In particular, the number of infections is large but the drug resistance is also large, which makes the patient afraid, the doctor is "confused" in the treatment. People infected with H. Painful and hemorrhagic stomach ulcers are complications of peptic ulcers. In some cases, peptic ulcer is more severe when complications such as gastrointestinal bleeding, atrophic inflammation of the gastric mucosa, transformation of the gastric mucosa such as dysplasia, and real According to Dr.
Therefore, it is important to immediately diagnose a patient infected with H. Here we encounter many cases of adults and children infected with H. Doctors also believe that the main cause of the spread of H. Most of Southeast Asians live emotionally, respectfully, so they eat and drink, they don't consider and be vigilant, but eat together. That creates the advantage of infection, spread HP.
