Antibiotic Susceptibility of Helicobacter pylori Clinical Isolates in Hamadan, West of Iran

Abstract: A B S T R A C TBackground: Surveillance data on Helicobacter pylori antibiotic susceptibilities are limited in Hamadan, Iran. Since antibiotic resistance is one of the reasons in therapies failure. Objectives: Thus the resistance patterns of H. pylori strains to the antibiotics metronidazole, clarithromycin, amoxicillin and tetracycline were evaluated. Patients and Methods: Gastric biopsy specimens of 153 patients with nonulcer dyspepsia, peptic ulcer dyspepsia, and peptic cancer collected during May 2010 to F… Show more

“…Resistance to drug combination was found among studied isolates in which 3.3% of isolates were resistant to four combined drugs, 3.3% to three combined drugs and variable resistant patterns to two combined drugs (Table 2). High rate of resistance (51.3%) was found to metronidazole which was comparable to that recorded by [13,14,15] who found that 57.5%, 51.5% and 56.3% of H. pylori isolates from Iranian patients were resistance to metronidazole respectively and Mansour et al, [16] found that 56.8% of the H. pylori isolates from Tunisian patients were resistance to metronidazole, but much lower than those found by Aboderin et al, [17] who found that 100% of H. pylori isolates from Nigerian patients were resistance to metronidazole and Majlesi et al, [18] who found 63.8% of H. pylori isolates from Iran were resistance to metronidazole. This high rate of resistance to metronidazole may be due to the wide use of this drug for other infections such as dental, gynecological and parasitic infections [19,20].…”

“…This high rate of resistance to metronidazole may be due to the wide use of this drug for other infections such as dental, gynecological and parasitic infections [19,20]. Resistance to clarithromycin was 10% which is lower than those recorded in other part of the world such as Mohammedi et al, [13], Mirzaei et al, [15] and Majlesi et al, [18] who found that 26.5%, 16.7% and 14.6% of the H. pylori isolates from Iranian patients were resistance to clarithromycin respectively, Mansour et al, (2010) from Tunisia found 15.4% were resistance and Aboderin et al, [17] from Nigeria found 100% were resistance. Resistance to clarithromycin can be developed either by using this drug as a key component of the drug combination used against H. pylori or used for the treatment of respiratory tract infection or due to the previous consumption of macrolides which induce cross resistance to clarithromycin [21].…”

“…In Iran, Clarithromycin resistance has increased from 1.4% in 1997 [13] to 26.5% in 2013 [14] . The rate is even reported higher in Turkey and Bahrain [15][16][17] .…”
