Is a 25-year-old patient with Helicobacter pylori (H. pylori) infection and symptoms of dyspepsia, including epigastric burning, chest tightness, dysphagia, regurgitation, and globus sensation, who has shown improvement with antibiotic treatment but now experiences bloating, nausea, and cramps, likely experiencing antibiotic side effects or requiring further investigation for other conditions, given normal blood work and ultrasound results?

From the Guidelines

The patient should complete the H. pylori eradication regimen as the symptoms are likely related to the infection and the new symptoms of bloating, nausea, and cramps are probably side effects of the antibiotics. Given the patient's significant symptom improvement during treatment and normal blood work and ultrasound, it is reasonable to attribute the symptoms to H. pylori infection rather than stomach cancer 1. The standard H. pylori eradication regimen, as recommended by the European Helicobacter Pylori Study Group, typically consists of a proton pump inhibitor plus two antibiotics for 7-14 days 1. The American Gastroenterological Association also suggests that patients who respond to H. pylori test and treat or PPI therapy can be managed without further investigation, and endoscopy usually adds little in young patients without alarm features 1. Some key points to consider in managing this patient include:

• Completing the full course of H. pylori eradication treatment despite the side effects of bloating, nausea, and cramps
• Managing antibiotic-associated symptoms with probiotics, hydration, and smaller meals
• Planning follow-up testing to confirm H. pylori eradication at least 4 weeks after completing treatment
• Considering endoscopy if symptoms persist after confirmed eradication or worsen significantly The patient's age, health status, and response to treatment all support the diagnosis of H. pylori infection over stomach cancer, and the current treatment approach is appropriate 1.

From the FDA Drug Label

1.2 Helicobacter pylori Eradication to Reduce the Risk of Duodenal Ulcer Recurrence Eradication of H. pylori has been shown to reduce the risk of duodenal ulcer recurrence. Triple Therapy Omeprazole delayed-release capsules in combination with clarithromycin and amoxicillin, is indicated for treatment of patients with H pylori infection and duodenal ulcer disease (active or up to 1-year history) to eradicate H. pylori in adults.

The patient's symptoms improved a lot during the H. pylori treatment regimen, which suggests that H. pylori was likely the cause of the symptoms. Given that the patient is H. pylori positive and the symptoms improved with treatment, it is likely that H. pylori was the primary cause of the symptoms, and stomach cancer is less likely. The new symptoms of bloating, nausea, and cramps could be side effects of the antibiotics. However, since blood work and ultrasound are normal, and the patient's symptoms improved with treatment, no further investigation is warranted at this time, but monitoring of the patient's symptoms is recommended. 2

From the Research

Patient Symptoms and H. pylori Infection

• The patient is experiencing symptoms such as burning in the stomach, tightness in the chest, difficulty swallowing, indigestion, heartburn, regurgitating, and globus sensation, which are commonly associated with H. pylori infection 3.
• The patient is H. pylori positive, which suggests that the infection is likely the cause of their symptoms.

Treatment Options for H. pylori Infection

• The current treatment regimen for H. pylori infection typically involves a combination of antibiotics and a proton pump inhibitor (PPI) 4, 5.
• Studies have shown that quadruple therapy regimens, which include two antibiotics, a PPI, and either clarithromycin or metronidazole, can be effective in eradicating H. pylori infection 6, 7.
• The choice of treatment regimen may depend on factors such as antibiotic resistance patterns and patient tolerance.

Patient Response to Treatment

• The patient's symptoms improved significantly during the initial treatment regimen, which suggests that the treatment is effective in reducing the bacterial load and alleviating symptoms 3.
• However, the patient has recently experienced bloating, nausea, and cramps, which may be side effects of the antibiotics or indicative of another underlying condition.

Further Investigation

• Given the patient's age and lack of risk factors, stomach cancer is unlikely, but it is essential to continue monitoring the patient's symptoms and response to treatment 3.
• The patient's blood work and ultrasound results are normal, which suggests that there are no underlying conditions that need to be addressed.
• Further investigation may be necessary to determine the cause of the patient's recent symptoms and to adjust the treatment regimen as needed.
