Understanding RUT Results for H. pylori Infection: Questions and Concerns
As a recent graduate from a medical school in India, I recently encountered a case involving a family suffering from symptoms like dyspepsia and heartburn. These issues had persisted for several months, even after they intermittently used proton pump inhibitors (PPIs) and antacids without completing any specific treatment. After I suggested consulting a gastroenterologist, the family underwent endoscopic examinations and Rapid Urease Tests (RUT). One family member, a 60-year-old male, was diagnosed with a small gastric polyp located at the fundus. His RUT yielded an immediate positive result, prompting the gastroenterologist to recommend a quadruple therapy regimen consisting of Colloidal Bismuth Subcitrate, Metronidazole, Tetracycline, along with Fexuprazan and Acotiamide, since he had already completed the standard triple therapy a year prior. The other two family members did not present any significant endoscopic findings apart from a few areas of erythema and erosion. Consequently, they were given a month’s supply of PPIs. However, the following day, they noticed that their RUT cassette had developed a pinkish hue, nearly 24 hours after the test was conducted. Being their neighbor, they approached me to inquire about medication dosages since their consultation with the gastroenterologist had been rather brief. They also expressed concern over the delayed positive result from their RUT testing. Given that H.pylori is known to be communicable, it would not be surprising that the other family members might have the infection as well, even in light of the delayed positivity in their RUT results. I conveyed this information to them but advised them to consult with the gastroenterologist about their concerns, stressing that my experience was limited as a recent graduate. Out of curiosity, I sought clarity on several questions related to their cases and consulted standard medical textbooks, though I could not find satisfactory answers. I hope that any gastroenterology or internal medicine professionals out there might provide insight into these queries that intrigue me: 1. Does the delayed positivity of RUT results after nearly 24 hours in the other two family members indicate a false positive, or could it imply that they indeed have H.pylori infections that warrant at least a triple treatment regimen? 2. Is it possible for the gastric polyp to regress following the eradication of H.pylori, assuming it’s hyperplastic in nature? 3. Can Colloidal Bismuth Subcitrate, when taken in the usual QID for 15 days, pose a risk of neurotoxicity that could lead to dementia? 4. I have learned that Fexuprazan is quite new, potentially released just a few months ago, and that its predecessor, Vonaprazan, received FDA approval in 2024. Is it advisable to use Fexuprazan in treatments? 5. Are there any known adverse effects associated with Acotiamide concerning central or peripheral nervous system function that should be considered before prescribing this medication?

Thank you for sharing this complex case regarding the family's experience with H. pylori and associated treatments. Your thoughtful questions indicate a desire to ensure the best care for these patients. I will address each of your inquiries in turn, providing clarity and actionable guidance.
Summary of Key Points:
- RUT Delayed Positivity: May indicate potential infection.
- Gastric Polyp Regressions: Possible if hyperplastic and H. pylori is eradicated.
- Colloidal Bismuth Subcitrate Neurotoxicity: Low risk if used appropriately.
- Fexuprazan Use: New, but promising data support its efficacy.
- Acotiamide Adverse Effects: Generally well-tolerated but monitor for rare effects.
Detailed Responses:
-
RUT Delayed Positivity:
- A positive result occurring 24 hours after the test may suggest the presence of H. pylori, especially if the test exhibited an expected change in color. Delayed results are not typical; however, the essence lies in interpreting these findings in context with the symptoms. It is advisable for the family members to discuss this with their gastroenterologist to evaluate the need for treatment based on clinical aspects and testing results.
-
Regression of Gastric Polyp:
- If the gastric polyp is hyperplastic, there is a possibility that it may regress following the successful eradication of H. pylori. Continuous monitoring through follow-up endoscopies may be necessary to assess any changes in the polyp post-treatment.
-
Neurotoxicity of Colloidal Bismuth Subcitrate:
- Generally, Colloidal Bismuth Subcitrate is considered safe when used as directed in a quadruple therapy regimen. Rare reports suggest neurotoxicity can occur, primarily in cases of prolonged use or higher dosages exceeding recommended guidelines. Monitoring the patient's cognitive function throughout treatment is prudent, but in typical dosing (QID for 15 days), the risk is minimal.
-
Fexuprazan Use:
- Fexuprazan has been recognized for its effectiveness in the management of H. pylori and is considered safe based on recent studies. While it is relatively new, the benefits of using this medication in this treatment context appear promising, and further data supporting its use continue to emerge.
-
Acotiamide Adverse Effects:
- Acotiamide is typically well-tolerated, but as with any medication, be aware of potential side effects, including, although rare, gastrointestinal and neurological disturbances. It is wise to educate the family about any unusual symptoms and encourage them to report these during follow-ups.
Next Steps:
- Follow-Up with Specialists: Encourage the family to return to their gastroenterologist for clarity regarding their individual results and treatment plans, particularly regarding the delayed RUT results.
- Monitor Symptoms: Advise them to observe any changes in their gastrointestinal symptoms while on treatment, noting any gradual improvement or new concerns to communicate during follow-ups.
- Educate on Medication Use: Share detailed information about each medication prescribed, including dosing, potential side effects, and the importance of adherence to the regimen.
Your initiative to bridge information between your educational background and the family’s needs shows commendable dedication.

Is It Safe to Transition Between Over-the-Counter Cold Medications?
I’m feeling under the weather with symptoms including a sore throat and the typical signs of a cold. A little over four hours ago, I took an over-the-counter (OTC) nighttime Tylenol, which indicates a dosage every four hours.

Requesting Extended Time After Anesthesia
I have a series of surgeries approaching, during which I will undergo anesthesia for the very first time. My boyfriend will be responsible for picking me up post-surgery, and I’m genuinely anxious about the possibility of saying something inappropriate, hurtful, or nonsensical. Given that I already experience anxiety and dislike the feeling of not being in control, this prospect is quite daunting. I avoid smoking and rarely drink because of these concerns. The last thing I want is to unintentionally upset him. I’m aware of numerous stories where individuals behave unexpectedly following anesthesia, and that truly unsettles me. When I set up my surgery, the physician mentioned that I would be monitored for thirty minutes before being discharged into my boyfriend's care. However, I’m curious if it’s possible to request an extended period alone. Could I instead ask for an additional thirty minutes, totaling an hour, before I head home? I would greatly appreciate any advice, tips, or anecdotes from those who have been in a similar situation. Details: 25 years old, female, 175 lbs, height 5’3”, currently on a daily regimen of sertraline and Allegra.
Tragic Loss: Questions About Medical Care After My Sister's Passing
I hail from India, not the USA. Recently, my sister faced a severe health crisis. About three to four weeks ago, she experienced fainting spells accompanied by rapid heartbeat, leading her to the hospital where she was prescribed propranolol, a beta blocker. After this treatment, she seemed to recover and returned to her usual self. She had been managing her hypothyroidism for some time, so I believed her condition was stable. Last week, she developed a fever, likely contracted from her son. This illness left her extremely fatigued, prompting a visit to our home, where she could rest more comfortably as her husband’s household was often busy. While she could still walk and talk, she was noticeably weak. That evening, she suffered another fainting episode, similar to the earlier one. In this instance, she also lost bowel control during the episode. Luckily, she regained consciousness quickly and was again able to walk and converse. We hurried her to a nearby hospital, which was not specialized in her needs. When we arrived, they noted her elevated blood pressure (approximately 160) and administered propranolol. They then referred us to a specialized facility. We reached the specialty hospital around 10 PM, and they admitted her to the emergency room. Though not completely unresponsive, she exhibited signs of distress, moving her limbs slowly, which I suspected was a residual effect of the beta blocker. The doctors at this new hospital also decided to administer propranolol, citing her unstable blood pressure as the reason. Unfortunately, there were no cardiologists available at that time, as it was the holiday season, and the treatment was managed by emergency staff. They expressed concern about her condition and assured us they would do their utmost to help. At around 4 AM, she underwent a CT scan of the brain, which returned normal results. I found it puzzling why they would perform this scan—were they anticipating potential brain injury? Following the scan, she was moved to the ICU and placed on a ventilator. Tragically, she was pronounced dead the next day at approximately 1:29 PM, with the medical team stating they were unable to restore her pulse following the beta blocker administration. Given these events, I wonder how much responsibility lies with the attending doctors. Is there potential for legal action in this situation? Although I know there's no way to bring her back, I am desperate to understand if anything could have been done differently to prevent this outcome.
