There is no accurate research value for the chance of primary failure of H. pylori eradication and secondary sterilization.
Clinically, the chances of failure of primary eradication of H. pylori and secondary sterilization are relatively high.
After the failure of H. pylori primary quadruple therapy, a certain degree of resistance may appear, and then the second sterilization will need to change the corresponding antibiotic type. Generally, amoxicillin combined with levofloxacin or tetracycline will be chosen for treatment, because amoxicillin has relatively less resistance.
If the treatment is complete after the second sterilization, it is also necessary to closely carry out the appropriate tests, because after the elimination of the situation may be re-infected. When there is Helicobacter pylori infection, the patient’s body will develop more antibodies.
In daily life, it is important to pay attention to dietary hygiene, do not eat half-baked food, and try to share meals to avoid bacterial infections and other diseases.
