Reduction of Helicobacter pylori and Lactobacilli.

Sub: Response to your editorial “causes of failure of eradication of Helicobacter pylori” (BMJ 2002; 325: 3-4, 6 July).
I have read with interest the editorial “causes of failure of eradication of Helicobacter pylori” (BMJ 2002; 325: 3-4, 6 July) by Dr. Jenks. It is difficult to eradicate Helicobacter pylori (H.pylori) from the gastric and duodenal mucosa and effective treatment requires multiple drug regiments(1). Antibiotic resistance to H. pylori is increasing due to widespread use of antibiotics(1). H.pylori organisms have been noted under the finger nails, between gums and teeth, dental plaque and over the tongue(2,3). In Vitro studies have shown that Lactic acid and Lactobacilli inhibit the growth of H.pylori(4). H. pylori has cytoplasmic urease which converts urea into carbon dioxide and ammonia(5). Lactic acid and Lactobacilli may prevent or suppress the production of ammonia which can inhibit the colonisation of H. pylori. Fermented milk products (curd, buttermilk and yoghurt) have lactic acid, Lactobacilli and nutrients. Intake of these fermented milk products will cause slower gastric emptying, and this will give enough time for local action of lactic acid and Lactobacilli to act on H. pylori organisms in the stomach. In addition to the use of antibiotics, proper washing of hands before meal and consumption of buttermilk(200-300 ml) twice a day before meal may help in reduction of H. pylori organisms.
