PATIENTS: Patients selected had unequivocal evidence of H. pylori infection based on the urease test, culture and histology and had either peptic ulcer disease or non-ulcer dyspepsia.
DESIGN: The study was a comparative and double-blind study and patients were randomized to receive either amoxycillin 750 mg t.i.d. and metronidazole 500 mg t.i.d. for 12 days or amoxycillin 1000 mg b.i.d. and metronidazole 500 mg b.i.d. for 12 days. Both groups also received famotidine 40 mg for 6 weeks.
MAIN OUTCOME MEASURE: Patients were assessed for successful eradication, defined as absence of bacteria in all tests, at least 4 weeks after completion of antibiotic therapy by repeat gastroscopy.
RESULTS: One hundred and twenty-nine patients were recruited for the study. Two patients defaulted follow-up, two patients were withdrawn from the study and six patients were found to be non-compliant with medications. The eradication rates of the t.i.d. regimen was higher than the b.i.d. regimen (per protocol (PP) analysis: 83.3% (50/60) vs. 76.3% (45/59), P=0.337; intention-to-treat (ITT) analysis: 78.5% (51/65) vs. 75.0% (48/64), P=0.642). Seventy-five patients had pre-treatment cultures checked for metronidazole resistance, 33 (44.0%) were found to be resistant. Acquired resistance occurred in 3/40 (7.5%) patients. Eradication rates of metronidazole-sensitive and metronidazole-resistant patients: t.i.d. regimen - 100% (17/17) and 88.2% (15/17), b.i.d. regimen - 19/21 (90.5%) and 11/15 (73.3%). Side effects were reported in up to 70% of patients but were mild and tolerable in the majority. Two patients were withdrawn from the study because of a fixed drug eruption in one and generalized macular rash in the other.
CONCLUSION: Combination amoxycillin and metronidazole is effective in eradicating H. pylori. There was a tendency for the t.i.d. regimen to be better than the b.i.d. regimen and for metronidazole-resistant infections to be associated with a lower eradication rate but these differences did not reach statistical significance.
Methods: A cross-sectional study, using a validated 23-item self-administered questionnaire, was conducted among pharmacists from 11 public hospitals in the State of Selangor, Malaysia, from December 2016 to January 2017. All public hospital pharmacists (n=432) were invited to participate in the survey. A 5-point Likert scale was employed in the questionnaire; the perception section was scored from 1 (strongly disagree) to 5 (strongly agree) while the practice section was scored from 1 (never) to 5 (always). Both descriptive and inferential statistical analyses were used to analyse data.
Results: Of the 432 pharmacists surveyed, 199 responded, giving a response rate of 46.0%. The majority of the respondents agreed (n=190, 95.5%) that the AMS programme improves patient care at their hospitals (median=5; IQR=1). Slightly less than half of the respondents indicated that a local antibiotic guideline was established in their hospitals (median=3, IQR=2.5), and had taken part in antimicrobial awareness campaigns to promote optimal use of antimicrobials in hospitals (median=3, IQR=1).
Conclusions: Overall, the perception and practices of the surveyed hospital pharmacists towards AMS programme were positive. National antibiotic guidelines, which take into consideration local antimicrobial resistance patterns, should be used fully to improve antimicrobial usage and to reduce practice variation. Collaboration among healthcare professionals should be strengthened to minimise the unfavourable consequences of unintended use of antimicrobial agents while optimising clinical outcomes.
AREAS COVERED: Antimicrobial stewardship programs improve rational antibiotic use, reduce antimicrobial resistance, decrease complications of antibiotic use, and improve patient outcomes. Though health professional students recognize the importance and impact of antibiotic prescribing knowledge, many studies have consistently demonstrated low levels of confidence and competencies amongst students, highlighting that health professional schools failed to prepare them to prescribe antibiotics accurately.
EXPERT OPINION: There is an urgent call for the integration of antimicrobial stewardship teaching at the undergraduate level of medical education to train future prescribers on this critical aspect of public health. Proper undergraduate education on rational antibiotics use would enable health professional graduates to enter clinical practice with adequate competencies to become rational prescribers.
METHODS: This point prevalence survey (PPS) was conducted in 13 hospitals among 7 different cities of Pakistan. The survey included all inpatients receiving an antibiotic on the day of PPS. A web-based application was used for data entry, validation, and reporting as designed by the University of Antwerp (www.global-pps.com).
RESULTS: Out of 1954 patients, 1516 (77.6%) were treated with antibiotics. The top three most reported indications for antibiotic use were prophylaxis for obstetrics or gynaecological indications (16.5%), gastrointestinal indications (12.6%) and lower respiratory tract infections (12.0%). The top three most commonly prescribed antibiotics were ceftriaxone (35.0%), metronidazole (16.0%) and ciprofloxacin (6.0%). Out of the total indications, 34.2% of antibiotics were prescribed for community-acquired infections (CAI), 5.9% for healthcare-associated infections (HAI), and 57.4% for either surgical or medical prophylaxis. Of the total use for surgical prophylaxis, 97.4% of antibiotics were given for more than one day.
CONCLUSIONS: Unnecessary prophylactic antibiotic use is extremely high, and broad-spectrum prescribing is common among hospitals in Pakistan. There is an urgent need to work on the national action plan of Pakistan on antibiotic resistance to address this.
