Te signifcance of the H. pylori for the human diseases were frst acknowledged at 1983. Nearly 60 percent of the world’s adult population has been infected. Tough they are asymptomatic, they can lead to peptic ulcers and gastritis, an infammatory condition of the stomach, in some people (Amieva M and Peek Jr RM, 2016). Gastric infec- tions caused by H. pylori is one of the most widespread infectious disease worldwide with an estimation of 40%-50% of the popula- - able for the testing the presence of H. pylori in patients sufering with ulcer or dyspepsia. Te commonly used tests are the evalua- tion of biopsy specimens during upper Gastrointestinal tract (GI) I endoscopy, the detection of serum anti-H. pylori antibodies and breathe tests with 13 C-labeled urea (Howden CW and Hunt RH, H. pylori is adapted to live in harsh acidic environment and so they are well suited to survive in the stomach. Tese bacteria are capable of changing their surrounding environment and it reduc- es the acidity of stomach so they could live there. Te spiral shape of the bacteria helps in penetrating of the stomach lining, where they are protected by mucus from the body’s immune system. Tese bacteria lead to stomach related problems (McNamara D, et al., 2002). More than 80% of the people afected do not express any symp- toms and it may also play an important role in the natural stom- ach ecology. Nearly 50%-75% of the worldwide population has been afected by H. pylori infection. Over 70% of the people are afected in the developing countries whereas only 25%-50% of the population are afected in the developed countries (Howden CW and Hunt RH, 1998). It is revealed in the annual report that the rate of the infection in Asia is 4.3%-13% greater than the West, where the infection rate is only 0.5%-2.5% (Drumm B, et al., 2000). Studies has shown that in Asia the prevalence is greater in the over populated countries like China(58%), South Korea(60%), Vietnam(75%), India(79%), Bangladesh(92%) than the less popu- lated countries like Singapore(31%), Malaysia(36%), Japan(39%), Taiwan(55%) and Tailand(57%) (Graham DY and Qureshi WA, 2001). Most of the children are afected by this infection from the par- ents or siblings and they are also afected due to the transmission of the bacterium to the GI tract by oral cavity, by fecal-oral route or by human to human transmission (Zhao S, et al., 2014; Safavi M, et al., 2016). Te H. pylori infection is most commonly asso- ciated with the lower socioeconomic background, poor diet and hygiene, over-crowding, ethnicity, ages and sex, as well as less ed- ucated level and geographic location, which plays a major role in the distribution of the infection (Rana R, et al., 2017). Most afected person’s are asymptomatic, for which the reason is not very clear, but some person’s could be born with more resistant immune system. But when the symptoms occur, the may include: • An ache or burning pain in your abdomen • Abdominal pain that's worse when your stomach is empty • Nausea • Loss of appetite • Frequent burping • Bloating • Unintentional weight loss H. pylori can lead to various upper gastrointestinal disorders such as gastric infammation (gastritis), heartburn, gastro esophageal refux disease, gastric duodenal ulcer disease, gastric cancer and Mucosa-Associated Lymphoid Tissue (MALT). Several erad- ication measures are available to treat the infection caused by H. pylori and one of the most widely used method is the sever- al combined antibiotics, such as amoxicillin plus clarithromycin or metronidazole with a proton-pump inhibitor. Nowadays, the main problems faced towards H. pylori infection is antibiotic re- sistance, patients compliance and intolerance to therapeutic reg- imens. Antibiotic resistance is a major concern as the H. pylori becomes resistant to drugs and thus the treatment fails (Stollman NH and Graham DY, 2014). Tis resistance can be caused due to poor drug penetration, low drug concentration, short gastric residence time and also the antibiotic resistance represent a sig- nifcant health care burden on the society. Patient compliance also becomes a problem due to poor stability of antibiotics in gastric content which requires frequent administration of the antibiotics (Pacifco L, et al., 2010; Carraher S, et al., 2013). Te diferent ther- apies used for the treatment of H. pylori infection are standard, sequential, quadruple, concomitant and levofoxacin therapy. Tese therapies are best of the treatments and assure high cure rate. Tough, recently standard triple therapy has shown reduced efcacy due to antibiotic resistance. Bismuth quadruple, concom- ABSTRACT Helicobacter pylori (H. pylori) is a gram negative bacteria whose infection is highly prevalent among the human population and leads to gastrointestinal tract related diseases (gastric and duodenal ulcers, mucosa asso- ciated tissue lymphoma and gastric adenocarcinoma). Most people with H. pylori infection will never have any signs or symptoms. While this bacterium infects 50% of the world’s population, in Africa its prevalence reach as high as 80% as the infection is acquired during child- challenging due to increasing antimicrobial resistance.
