For years, doctors treated Helicobacter pylori infection without checking if it worked. As a result, antibiotic resistance grew, and fewer people got better. Now, we can test if the bacteria will respond to treatment.

This new way focuses on using antimicrobial stewardship for H pylori. It means doctors choose antibiotics carefully, based on what will work. This change has improved how we treat the infection.

Understanding Helicobacter Pylori Infection

Helicobacter pylori is a type of bacteria that causes stomach problems. It was found out in the 1980s. Doctors realized it could cause ulcers and cancer in the stomach. They also found out treating this infection could stop these diseases.

What is Helicobacter Pylori?

H. pylori is a common infection worldwide. It affects about half of all people. The bacteria usually enter the body in childhood. But we are not sure how exactly. Thanks to new tests, doctors can easily check for this infection.

Symptoms and Risk Factors

Many people with Helicobacter pylori do not feel sick. But, it can cause problems like stomach ulcers and cancer. People from poorer backgrounds, with many siblings, or people whose mothers had the infection, have a higher chance of getting it.

Prevalence and Epidemiology

If you are born outside of North America, you might be more likely to get this infection. In the U.S., it’s often found in immigrants and certain ethnic groups. However, the number of infections has gone down in recent years. From 2014 to 2020, it went from 50-55% to 43%.

Indications for Testing and Treatment

Testing is needed for H. pylori in some patients. If a patient has the infection, they should get treated. Anyone with peptic ulcer disease now or before needs testing.

This is unless their infection was shown to be cured already. Also, people with certain stomach conditions must be tested.

Peptic Ulcer Disease and Gastric Cancer

For patients with acid reflux, testing is not always needed. But, if they have had ulcers or stomach pain, they should be tested. If H. pylori is found because of reflux disease, treat it.

The ACG suggests testing before long-term NSAID use or with unknown anemia causes.

Unexplained Iron Deficiency Anemia

Clearing H. pylori can help with iron deficiency anemia. It can also help with blood issue problems. After treatment, blood issues might get better.

Long-term NSAID Therapy

Getting rid of H. pylori can lower the risk of ulcers in NSAID users. It’s good for preventing stomach bleeding too. This is especially true for people taking small amounts of aspirin or naproxen.

Diagnostic Tests for Helicobacter Pylori

Finding Helicobacter pylori (H. pylori) is key to treating it well. Tests like the urea breath test, fecal antigen test, or endoscopic biopsy are best for this.

Urea Breath Test

The urea breath test is a common, easy way to find H. pylori. Patients drink a solution with a special carbon. If H. pylori is there, the breath will show it. It works well for both grown-ups and kids over 6.

Fecal Antigen Test

The fecal antigen test also checks for H. pylori without invading the body. Scientists look for H. pylori signs in a stool sample. This is the top test for finding the infection.

Endoscopic Biopsy

Doctors can also check for H. pylori with an upper endoscopy. They take tiny pieces of the stomach to see if the bacteria are there. This is used when other tests don’t give clear answers or for certain patients.

Taking certain drugs can mess with the test results. Patients need to avoid antibiotics, proton pump inhibitors, and bismuth subsalicylate for a month before the test. This makes sure the tests work right.

First-Line Treatment Strategies

When dealing with Helicobacter pylori (H. pylori) infection, doctors use a mix of antibiotics and a proton pump inhibitor (PPI). For first-line treatments, they suggest several strategies.

Clarithromycin Triple Therapy

One common first-line therapy is the clarithromycin triple. Patients take a PPI, clarithromycin, and either amoxicillin or metronidazole for two weeks. But, if the area has a lot of clarithromycin resistance (more than 15%), they would pick other options.

Bismuth Quadruple Therapy

Another good first choice is the bismuth quadruple. It uses a PPI, bismuth, tetracycline, and a nitroimidazole for 10 to 14 days. This treatment works well for those who’ve used macrolides before or have a penicillin allergy.

Concomitant Therapy

Concomitant therapy also works, using a PPI, clarithromycin, amoxicillin, and a nitroimidazole for 10 to 14 days. It’s good because it works about as well as the triple therapy but is easier to tolerate.

Other first-line options are sequential therapy, where patients take a PPI and amoxicillin first, then switch to a combination of a PPI, clarithromycin, and a nitroimidazole. And there’s hybrid therapy, which starts with a PPI and amoxicillin, then becomes a mix of a PPI, amoxicillin, clarithromycin, and a nitroimidazole.

Management of Helicobacter Pylori Infection

Dealing with Helicobacter pylori (H. pylori) infection needs careful steps. It includes handling antibiotics well, keeping to the treatment plan, and checking if it works. These steps are key to removing the infection and stopping antibiotic problems.

Antimicrobial Stewardship

The aim of using antibiotics the right way is to beat H. pylori. This means using the right antibiotics that the infection can’t resist. Also, it involves the right doses, ways of taking the medicine, and for the right times. Doing this cuts down on the risk of creating superbugs.

Treatment Duration and Adherence

How long and how well patients follow their treatment plan really matter. Most treatments last 10 to 14 days. But, longer treatment often works better to kill the infection. Making sure patients finish all their medicine is so important. Stopping too soon makes the treatment less effective. It also adds to the problem of antibiotic resistance.

Monitoring Treatment Success

After treatment, it’s vital to check if it worked. Testing for a cure with a breath or stool test is smart. This check-up happens 4 to 6 weeks after ending treatment. It lets doctors catch if the infection is still there. Then, they can fix the issue right away. Watching how well treatments work helps doctors make better choices for the next steps. This is key for truly fighting off H. pylori.

Antibiotic Resistance and Susceptibility Testing

When treating Helicobacter pylori, knowing about antibiotic resistance is crucial. Unfortunately, the United States lacks enough data on H. pylori resistance. So, making treatment choices based on evidence is hard. Culture-based or molecular-based susceptibility tests help check resistance. But, they’re not widely used in the US.

Patterns of Antibiotic Resistance

Some antibiotics like clarithromycin and metronidazole don’t work well because of resistance. This resistance makes H. pylori infections harder to treat. Luckily, resistance to other drugs like amoxicillin is not common. We need more studies to find out about resistance locally and nationwide. This info would help pick the best treatments and keep antibiotic use careful.

Culture-based Susceptibility Testing

With culture-based testing, doctors can check which antibiotics may not work. They take stomach tissue samples to grow and test H. pylori. This test pinpoints which antibiotics the bug is likely resistant to. Yet, few places, including the US, can do this test.

Molecular-based Susceptibility Testing

Molecular tests, like PCR, show if H. pylori might resist certain antibiotics. These tests are more common and give quick results. By spotting resistance genes, these tests help choose the right antibiotic. This approach improves the chances of wiping out H. pylori.

Optimizing Treatment Regimens

Susceptibility testing has made it easier to pick the right antibiotics for H. pylori. This means doctors can choose the best helicobacter pylori infection natural treatment that the infection is likely to respond to. They might prescribe medicine that’s based on what the tests show, aiming for a more effective cure. This way, treatment can work better at getting rid of H. pylori.

Tailoring Therapy Based on Susceptibility

Using tests to see what medicine will work better against H. pylori is a big step forward. It follows the idea of using antibiotics only if we know they will help, which is good for everyone. Doctors now have the tools to give more personalized therapy, which increases the chance of wiping out H. pylori.

Emerging Treatment Options

Old treatments are still useful, but new ones are being looked at to fight antibiotic resistance in H. pylori. Vonoprazan and amoxicillin treatment is one of these new ways and looks promising. Its success, however, needs more checks in many places to make sure it really works worldwide.

Preventing Helicobacter Pylori Reinfection

Preventing Helicobacter pylori (H. pylori) reinfection is key after getting rid of the bacteria. Many risk factors make it more likely to get infected again. These include living in a place with lots of H. pylori, low hygiene, and being poor.

Risk Factors for Reinfection

People with low incomes and those from developing areas are at a higher risk of getting H. pylori again. This happens because they might not have good hygiene habits. They also might use water that’s not clean and this water can have the bacteria. Being close to infected people or living in a place where many people have H. pylori also raises the risk.

Hygiene and Lifestyle Modifications

There are effective ways to lower the chance of getting H. pylori again. Doing simple things like washing hands often, especially before eating and after using the bathroom, can keep the infection away. It’s also important to drink clean water, not water that might be dirty.

Teaching people about the value of keeping food and surroundings clean can also help. By making these simple changes in hygiene and life habits, you can make it unlikely to have Helicobacter pylori come back.

Special Considerations

Dealing with Helicobacter pylori infection requires extra thought in certain cases. The number of kids with this infection can change a lot, up to 50% in some places. In pregnant women, it is linked to issues like hyperemesis gravidarum, which causes severe nausea and vomiting, during pregnancy. But, not all pregnant women need to be checked for this. Only those with stomach ulcers or other problems from H. pylori should consider treatment.

Pediatric Patients

Kids with this infection face some challenges in treatment. Things like antibiotic resistance and getting kids to follow the treatment can make it hard. Doctors need to think carefully about testing and treating kids without symptoms, especially in places where many kids have helicobacter pylori. For kids showing symptoms, it’s best to use simpler tests first, like the urea breath test, instead of doing a biopsy with a camera.

Pregnancy and Lactation

For pregnant women and those who are breastfeeding, treating this infection can be tricky. The aim is to balance the good that can come from getting rid of H. pylori with the risk of using antibiotics. In fact, for pregnant women not showing symptoms, testing and treating them isn’t common advice. But, if a pregnant woman has a stomach ulcer or a similar problem, then doctors should look at treating it carefully, thinking about the mother and the baby.

CharacteristicPediatric PatientsPregnancy and Lactation
PrevalenceUp to 50% in some regionsVarying, with some correlation to adverse outcomes
Diagnostic ApproachPrefer non-invasive tests (urea breath test, stool antigen)Caution with antibiotic exposure, individualized approach
Treatment ConsiderationsAntibiotic resistance, compliance, adverse effectsBalancing benefits and risks for mother and fetus

Although we’ve made progress in handling Helicobacter pylori, thinking about kids and pregnant women needs extra care. Doctors should think about how much the infection spreads, which tests are best, and how treatment might affect the patient and their family.


The way we handle Helicobacter pylori infection has changed a lot. Now, we focus on using antibiotics wisely and testing first to see which ones work best. By doing this, we pick the right medicines based on what works in our area and for each patient. This helps get rid of the infection better. Also, keeping an eye on which bacteria resist antibiotics is super important. This helps us always get better at treating this big health problem.

The key point on fighting Helicobacter pylori is using antibiotics carefully and testing to see which ones work. We have good treatments that we can adjust to fit what’s best for our local area and for different patients. This improves our chances of curing the infection. And, it’s crucial to keep checking how bacteria react to antibiotics. This way, we can keep getting better at treating this serious health issue.

Even as we keep finding new ways to deal with Helicobacter pylori, doctors must stay alert. We need to follow important practices when using antibiotics and testing them. By picking treatments that match what’s going on in our area and every patient’s needs, we can do a better job of wiping out the infection. This is how we make sure those with this common health issue get the best care.
