Helicobacter Pylori or widely known as H. Pylori. The first time i come across this was when i was enrolled in Microbiology class. H. Pylori sounds cute. Right? Cute but deadly. hahaha. I thought of blogging about this bacteria because several friends of mine are positive with H. Pylori after having done endoscropy and one mom of my friend, it helps her develop stomach cancer. So I hope that with this post, I can share to you abit of the important facts about this bacterium.
WHAT IS H. PYLORI?
Helicobacter pylori (H. pylori) is a bacterium that causes chronic inflammation of the inner lining of the stomach (gastritis) in humans. This bacterium also is the most common cause of ulcers worldwide. H. pylori infection is most likely acquired by ingesting contaminated food and water and through person to person contact. Infected individuals usually carry the infection indefinitely unless they are treated with medications to eradicate the bacterium. One out of every six patients with H. pylori infection will develop ulcers of the duodenum or stomach. H. pylori also is associated with stomach cancer and a rare type of lymphocytic tumor of the stomach called MALT lymphoma.
HOW IS IT DIAGNOSED?
1. Blood antibody tests
2. urea breath tests (UBT)
3. stool antigen test
4. endoscropic biopsies
HOW TO TREAT?
H. pylori is difficult to eradicate from the stomach because it is capable of developing resistance to commonly used antibiotics. Therefore, two or more antibiotics usually are given together with a PPI and/or bismuth containing compounds to eradicate the bacterium. (Bismuth and PPIs have anti-H. pylori effects.) Examples of combinations of medications that are effective are:
a PPI, amoxicillin (Amoxil) and clarithromycin (Biaxin)
a PPI, metronidazole (Flagyl), tetracycline and bismuth subsalicylate
These combinations of medications can be expected to cure 70%-90% of infections. However, studies have shown that resistance of H. pylori (failure of antibiotics to eradicate the bacteria) to clarithromycin is common among patients who have prior exposure to clarithromycin or other chemically similar macrolide antibiotics (such as erythromycin). Similarly, H. pylori resistance to metronidazole is common among patients who have had prior exposure to metronidazole. In these patients, doctors have to find other combinations of antibiotics to treat the H. pylori. Antibiotic resistance is another reason why antibiotics should be used carefully and judiciously for the right reasons, and indiscriminate use of antibiotics for improper reasons should be discouraged.
WHY TREAT H. PYLORI?
Chronic infection with H. pylori weakens the natural defenses of the lining of the stomach against the ulcerating action of acid. Medications that neutralize stomach acid (antacids), and medications that decrease the secretion of acid in the stomach (H2-blockers and proton pump inhibitors or PPIs) have been used effectively for many years to treat ulcers.
Antacids, H2-blockers and PPIs, however, do not eradicate H. pylori from the stomach, and ulcers frequently return promptly after these medications are discontinued. Hence, antacids, H2-blockers or PPIs have to be taken daily for many years to prevent the return of the ulcers and the complications of ulcers such as bleeding, perforation, and obstruction of the stomach. Eradication of H. pylori prevents the return of ulcers and ulcer complications even after the medications are stopped. Eradication of H. pylori also is important in the treatment of the rare condition known as
MALT lymphoma of the stomach. Treatment of H. pylori to prevent stomach cancer is still controversial.

Welcome to The Dating Profiles Meme. This meme is based on a feature from WTIT: The Blog authored by Bud Weiser. This is a bit different than an “answer this question” meme. Either you have used sites such as Match.com or Yahoo Personals or you’ve read them. Weekly, we scour those on-line dating sites to respond either a person’s profile or often their headlines as most of us would really like to do. We use only “lines” that are gender-neutral. So, your mission is to respond to ten we choose each week. Seriously or with humor is your choice! The spelling or grammar errors were in the original profiles. Join us each and every Friday!
