Understanding H. pylori and Extra-Gastric Disorders
The bacterium Helicobacter pylori (H. pylori) primarily infects the stomach but can be associated with various conditions outside the digestive tract (extra-gastric disorders).
Conditions Benefiting from H. pylori Eradication
Research suggests that eradicating H. pylori infection can be beneficial in managing certain extra-gastric conditions:
- Unexplained vitamin B12 deficiency: H. pylori can interfere with B12 absorption. Eradication often improves B12 levels.
- Idiopathic thrombocytopenic purpura (ITP): Eradicating H. pylori has been shown to increase platelet counts in some patients with ITP.
- Iron deficiency anaemia (IDA) without obvious GI bleeding: H. pylori can contribute to IDA through various mechanisms, including inflammation and blood loss. Eradication may help resolve the anaemia.
Extra-Gastric Disorder NOT Benefited (The Exception)
Acute glomerulonephritis is a kidney inflammation condition. While infections can sometimes trigger or worsen kidney issues, a direct, consistent benefit from H. pylori eradication for acute glomerulonephritis is not established, unlike the other listed conditions.
Therefore, eradication of H. pylori infection is least likely to prove beneficial in acute glomerulonephritis compared to the other options.

Select the correct answer using the code given below: - Which one of the following statements about Barrett's Oesophagus is NOT correct?
Risk scoring system used to stratify the patients of acute upper gastrointestinal bleeding to predict the need for intervention to treat bleeding is:
- Consider the following statements in respect of Helicobacter Pylori :
1. It is a gram positive, spiral-shaped bacterium.
2. It uses an adhesion molecule (BabA) to bind to the 'Lewis b' antigen on gastric epithelial cells.
3. It produces 'urease' enzyme that helps to raise the pH around the bacterium.
4. It exclusively colonises only 'gastric-type' epithelium.
Which of the above statements are correct?
