    The study was intended to develop a new intra-gastric floating in situ microballoons system for controlled delivery of rabeprazole sodium and amoxicillin trihydrate for the treatment of peptic ulcer disease. Eudragit S-100 and hydroxypropyl methyl cellulose based low density microballoons systems were fabricated by employing varying concentrations of Eudragit S-100 and hydroxypropyl methyl cellulose, to which varying concentrations of drug was added, and formulated by stirring at various speed and time to optimize the process and formulation variable. The formulation variables like concentration and ratio of polymers significantly affected the in vitro drug release from the prepared floating device. The validation of the gastro-retentive potential of the prepared microballoons was carried out in rabbits by orally administration of microballoons formulation containing radio opaque material. The developed formulations showed improved buoyancy and lower ulcer index as compared to that seen with plain drugs. Ulcer protective efficacies were confirmed in ulcer-bearing mouse model. In conclusion, greater compatibility, higher gastro-retention and higher anti-ulcer activity of the presently fabricated formulations to improve potential of formulation for redefining ulcer treatment are presented here. These learning exposed a targeted and sustained drug delivery potential of prepared microballoons in gastric region for ulcer therapeutic intervention as corroborated by in vitro and in vivo findings and, thus, deserves further attention for improved ulcer treatment.

    A 5-year-old girl presented with a history of
    fever for four days associated with odynophagia.
    She was treated with amoxycillin prescribed
    by a general practitioner for 3 days prior to
    presentation. However, the symptoms were
    worsening and associated with drooling of
    saliva and poor oral intake. There was history
    of recurrent acute tonsillitis in the past two
    years, with 5 to 6 episodes per year. The child
    had completed regular immunizations up to her
    current age. There was no similar presentation
    amongst family members and friends. (Copied from article).

    Background and Aim: Aeromonas hydrophila is a major cause of bacterial infections affecting a wide range of warm water fishes worldwide. In Malaysia, A. hydrophila isolations from diseased fishes were previously reported; however, with limited information. The present study investigates the antibiotic susceptibility and pathogenicity of A. hydrophila isolated from farmed red hybrid tilapia (Oreochromis spp.) in Malaysia.

    Materials and Methods: A. hydrophila was biochemically identified and subjected to antibiotic susceptibility tests. The isolate was then intraperitoneally injected into red hybrid tilapia, and the mortality, clinicopathological changes, and LD50 were determined up to 240 h post-infection (hpi).

    Results: The isolate demonstrated multiple antibiotic resistances (MAR) toward amikacin, ampicillin, cefotaxime, amoxicillin, trimethoprim-sulfamethoxazole, erythromycin, and streptomycin, with a MAR index of 0.5. The experimental infection of A. hydrophila at 105 CFU/mL in the red hybrid tilapia resulted in 100% mortality at 240 hpi. The LD50 was determined at 1.1×104 CFU/mL. Infected fish demonstrated occasional erratic swimming patterns, localized hemorrhages and depigmentation on the body and operculum areas, fin erosion, enlargement of the gall bladder, and hemorrhage in internal organs. Microscopic observation of infected fish revealed brain congestion, tubular necrosis, and glomerular shrinkage in the kidneys, necrosis of hepatocytes, and congestion of blood vessels in the liver.

    Conclusion: The high virulence of A. hydrophila to the red hybrid tilapia emphasizes the importance of active, on-going monitoring of its prevalence in Malaysian tilapia farming.

    Antimicrobial resistance (AMR) has become a major problem worldwide with significance public health impact in both animal and human populations. Staphylococcus aureus (S. aureus) is a common pathogen in domestic livestock and Escherichia coli (E. coli) is a normal flora in the gut and these organisms are considered as effective indicators for AMR surveillance. Increased in antimicrobial resistance of these bacteria in veterinary medicine leads to difficulties in choosing effective antibiotics to treat diseases they caused. This study aimed to evaluate the susceptibility of S. aureus and E. coli isolated from dairy goats in selected farms located in Selangor, Malaysia against different antibiotics. Milk and faecal samples were collected from 36 dairy goats and samples were prepared for the isolation of S. aureus and E. coli isolates respectively. The isolates were subjected to antibiotic susceptibility test. All 11 (100%) E. coli isolates showed resistance to amoxicillin and penicillin while 3 (27%) of the 11 S. aureus isolates, showed resistance towards the same class of antibiotic. Both S. aureus and E. coli isolates showed high susceptibility to four antibiotics, namely trimethoprim-sulfamethazole, neomycin, tetracycline and enrofloxacin. This study provided information regarding the antibiotic resistance of S. aureus and E. coli in relation to the antimicrobial usage practice in selected dairy goat farms located in Selangor, Malaysia.

    Acute ptosis due to preseptal cellulitis requires urgent medical attention, as the infection can extend posteriorly into the orbit, leading to significant visual and cerebral complications. We report a case of a 58-year-old woman with uncontrolled diabetes mellitus presenting with acute ptosis due to preseptal cellulitis. After initial resolution of fever with intravenous amoxicillin-clavulanate, she experienced a seizure due to cerebral abscess a week later and was treated with intravenous ceftriaxone. Preseptal cellulitis is usually treated on an outpatient basis with oral antibiotics, as it rarely extends posteriorly to cause cerebral complications. We wish to highlight the importance of admitting patients with preseptal cellulitis in patients with uncontrolled diabetes for intravenous antibiotics due to the potential for visual and cerebral complications.

    Backgrounds & Objective: Antimicrobial resistance is an alarming public health threat that requires urgent global solution. Implementation of antimicrobial stewardship program (ASP) is an essential practice element for healthcare institutions in gate-keeping judicious antimicrobial use. This study highlighted the development, first year experience, and result of the implementation of ASP utilizing persuasive and restrictive approaches in a Malaysian district hospital.
    Methods: An observational study was conducted between January 2015 to December 2015 on implementation of ASP among hospitalized inpatients age 12 years old and above.
    Results: Recommendations were provided for 60% of cases (110 patients) with the average acceptance rate of 83.33%. Majority of the interventions were to stop the antimicrobial therapy (30.3%), and the most common audited antimicrobials was Piperacillin/Tazobactam (25.5%), followed by Meropenem (11.82%), Amoxicillin/Clavulanate and Vancomycin (8.18%) respectively. The concordance rate towards authorization policy was increased in 2015 (71.59% of cases) as compared before the implementation of ASP in 2014 (60.6% of cases). Restrictive enforcement under ASP had been shown to improve significantly adherence rate towards antimicrobials authorization policy (p-value: 0.004).
    Conclusion: ASP was successfully implemented in a district hospital. Future studies on its clinical outcomes are important to evaluate its effectiveness as well as focus on the improvement to the pre-existing strategies and measures.

    Background: (13) C – urea breath test (UBT) is sensitive and specific for detection of Helicobacter pylori (H. pylori) infection. Gastric biopsy culture for H. pylori confirms the diagnosis. Here, we analyzed data of all patients who were investigated for H. pylori infection using both tests throughout the year 2005. Materials and Methods : Retrospective data of 377 patients between the ages of 17 – 88 were identified through endoscopy records from January to December 2005. Upper endoscopy, UBT and gastric biopsy culture were performed on all patients simultaneously during each endoscopy session. Patients who had positive UBT and biopsy culture for H. pylori were treated with triple therapy of PPI, amoxicillin and clarithromycin for one week. A repeat of UBT was done at one-month post therapy. Results and Analysis: Twenty-eight patients on the list had no available data on UBT and were omitted from the analysis. Ethnic group Chinese comprised of 45.4% (n=163), followed by Malay, 37.3% (n=134), Indian, 10.6% (n=38) and others, 3.9% (n=14). UBT was positive in 23.7% (n=85)(figure1). H. pylori culture was positive in 19.2% (n=69)(figure1). Sixteen patients with UBT positive had H. pylori culture negative, 18.8% (n=16/85)(figure2). Five patients with H. pylori culture positive had UBT negative, 7.2% (n=5/69)(figure3). Ethnic group Indian had the highest incidence of UBT positive, 47.4% (n=18/38), followed by Others (Sikhs and foreigners) 42.8% (n=6/14), the Chinese 27.6% (n=45/163) and the Malays 11.6% (n= 16/138). UBT positive was the highest in the age group of 50 and above, 64.7% (n=55/85), followed by the age group between 30 to 49, 21.2% (n=18/85) and the age group of 29 and below, 14.5% (n=12/85). Out of the 85 UBT positive patients 91.8% (n=78/85)(figure4) of them responded to the conventional one week of triple therapy (PPI, amoxicillin, clarithromycin) with negative UBT at one-month post therapy compared to only 8.2% (n=7/85)(figure4) who failed with positive UBT at one-month post therapy.

    Salmonella has been reported to be presence both in raw and processed foods worldwide. In this study, the prevalence, quantification and antibiotic susceptibility of Salmonella isolated from raw vegetables or locally known as ulam such as asiatic pennywort (Centella asiatica (L) Urb), water dropwort (Oenanthe javanica (Blume) DC), long bean (Vigna sinensis EndL), and winged bean (Psophocarpus tetragonolobus (L) DC) obtained from retail markets in Selangor, Malaysia were carried out. From 96 samples tested, the overall prevalence of Salmonella spp. was 97.9%, Salmonella Enteritidis was 54.2% and Salmonella Typhimurium was 82.3% respectively. Samples were contaminated with Salmonella ranging from < 3 to 2400 MPN/g. Salmonella Enteritidis and Salmonella Typhimurium isolates obtained from the raw vegetables (ulam) were found to exhibit high resistance against ampicillin (100%), erythromycin (100%), amoxicillin/clavunic acid (81.3%), cephalothin (75%), streptomycin (50%) and ciprofloxacin (50%). All Salmonella isolates showed multi drug resistant (MDR) profile with each isolate being resistant to 3 or more antibiotics. The multiple antibiotic resistance (MAR) index of Salmonella isolates ranged from 0.27 to 0.55 for Salmonella Enteritidis and 0.27 to 0.82 for Salmonella Typhimurium. The presence of Salmonella on raw vegetables (ulam) and high antibiotic resistance isolates indicated that raw vegetables could be contaminated and thus imposes possible health risk to local consumers.

    Occurrence of pharmaceutical residues in drinking water has been widely reported in countries that have registered steady economic growth. This can exert concerns among the general consumers, prompting them to explore the potential human health risks associated with continuous exposure to pharmaceuticals. However, such an occurrence is rarely reported in developing or under-developed countries. To give more contexts, this study looked at the presence of nine pharmaceutical residues in drinking water (amoxicillin, caffeine, chloramphenicol, ciprofloxacin, dexamethasone, diclofenac, nitrofurazone, sulfamethoxazole, and triclosan) at Putrajaya residential area in Malaysia. Additionally, the potential health risks associated with contaminated drinking water were investigated. This study has found the presence of pharmaceutical residue concentrations up to 0.38 ng/L, with the highest concentration of caffeine (0.38 ng/L) and the lowest concentration of diclofenac (0.14 ng/L). In comparison, all the nine pharmaceutical residues were substantially lower than previously reported studies. In general, Hazard Quotient (HQ) values indicated that low potential health hazards were present for all age groups. Nevertheless, quantitative occurrences of pharmaceutical residues in drinking water will help guide future toxicological studies to examine other chronic effects, while canvassing for proper framework to look into the water risk management and regulation in Malaysia.

    AIM: The aim of this study is to identify antibiogram and heavy metal resistance pattern of Aeromonas hydrophila and Edwardsiella tarda isolated from red hybrid tilapia (Oreochromis spp.) coinfected with motile aeromonas septicemia and edwardsiellosis in four commercial fish farms.

    MATERIALS AND METHODS: A. hydrophila and E. tarda were isolated using glutamate starch phenol red and xylose lysine deoxycholate (Merck, Germany) as a selective medium, respectively. All the suspected bacterial colonies were identified using conventional biochemical tests and commercial identification kit (BBL Crystal, USA). Susceptibility testing of present bacterial isolates to 16 types of antibiotics (nalidixic acid, oxolinic acid, compound sulfonamides, doxycycline, tetracycline, novobiocin, chloramphenicol, kanamycin, sulfamethoxazole, flumequine, erythromycin, ampicillin, spiramycin, oxytetracycline, amoxicillin, and fosfomycin) and four types of heavy metals (mercury, chromium, copper, and zinc) were carried out using disk diffusion and two-fold agar dilution method, respectively.

    RESULTS: Three hundred isolates of A. hydrophila and E. tarda were successfully identified by biochemical tests. Antibiotic susceptibility testing results showed that 42.2% of the bacterial isolates were sensitive to compound sulfonamides, sulfamethoxazole, flumequine, oxytetracycline, doxycycline, and oxolinic acid. On the other hand, 41.6% of these isolates were resistant to novobiocin, ampicillin, spiramycin, and chloramphenicol, which resulted for multiple antibiotic resistance index values 0.416. Among tested heavy metals, bacterial isolates exhibited resistant pattern of Zn(2+) > Cr(6+) > Cu(2+) > Hg(2+).

    CONCLUSION: Results from this study indicated that A. hydrophila and E. tarda isolated from coinfected farmed red hybrid tilapia were multi-resistant to antibiotics and heavy metals. These resistant profiles could be useful information to fish farmers to avoid unnecessary use of antimicrobial products in the health management of farmed red hybrid tilapia.

    INTRODUCTION: The access, watch, and reserve (AWaRe) classification of antibiotics was developed in 2019 by the WHO Expert Committee on the Selection and Use of Essential Medicines as a tool to support antibiotic stewardship efforts at local, national, and global levels. The objectives of this study were to assess the availability of antibiotics as per WHO AWaRe classification at community pharmacies located around a tertiary care hospital in Lalitpur and to compare these antibiotics with the national essential medicine list of Nepal.

    METHOD: The cross-sectional study was conducted at community pharmacies located within a two-kilometer radius of a teaching hospital from August to November 2022. A total of 82 community pharmacies registered with the Nepal Chemist and Druggists Association and the Department of Drug Administration were studied. Data was collected using a standard proforma containing the names of the antibiotics classified as per the WHO's AWaRe classification.

    RESULTS: Access group of antibiotics, Ampicillin, (82;100%), Amoxycillin, (82;100%), Flucloxacillin, (82;100%), and Metronidazole, (82;100%) were available in all community pharmacies. Results from the watch group showed that Azithromycin, (80; 97.6%) was available in all pharmacies followed by Cefixime, (80; 97.6%), Ciprofloxacin, (73; 89%), Levofloxacin, (74; 90.2%)and Ofloxacin, (74; 90.2%). Linezolid, (24; 29.3%) was the most common antibiotics available from the reserve group of antibiotics. Colistin was the second commonly available antibiotic. The most available antibiotic from the not recommended group were Ampicillin/Cloxacillin (82; 100%), followed by Piperacillin/Sulbactam, (39; 47.6%). There were differences in the classification of antibiotics between the WHO AWaRe list and the Essential Medicines list of Nepal in terms of numbers of antibiotics listed.

    CONCLUSION: Antibiotics from the not recommended and reserve groups were commonly available in community pharmacies. The implementation of antibiotic guidelines should be emphasized along with strict monitoring of the sale of antibiotics without a prescription in community pharmacy settings.

    A previously healthy woman in her mid-70s presented with right upper quadrant abdominal pain, fever, intermittent chills and malaise for 1 week. She was clinically septic with raised inflammatory markers. Her blood culture revealed Pasteurella multocida, which was susceptible to penicillin and amoxicillin-clavulanic acid. CT of liver revealed an abscess of 8.0×7.9×8.5 cm at the left lobe of the liver. However, the abscess was not amenable for surgical or radiological drainage. She was a farmer and had close contact with her pet cats. She was occasionally scratched by her cats when caring for them. The liver abscess resolved completely without drainage after prolonged antimicrobial therapy of 109 days. She commenced on 63 days of intravenous antimicrobials and 46 days of oral amoxicillin-clavulanic acid. This case illustrated P. multocida bacteraemia with a large liver abscess in an immunocompetent adult after non-bite exposure.

    The synthesis of nanocomposite with controlled surface morphology plays a key role for pollutant removal from aqueous environments. The influence of the molecular size of the polyelectrolyte in synthesizing silica-iron oxide core-shell nanocomposite with open shell structure was investigated by using dynamic light scattering, atomic force microscopy, and quartz crystal microbalance with dissipation (QCM-D). Here, poly(diallydimethylammonium chloride) (PDDA) was used to promote the attachment of iron oxide nanoparticles (IONPs) onto the silica surface to assemble a nanocomposite with magnetic and catalytic bifunctionality. High molecular weight PDDA tended to adsorb on silica colloid, forming a more extended conformation layer than low molecular weight PDDA. Subsequent attachment of IONPs onto this extended PDDA layer was more randomly distributed, forming isolated islands with open space between them. By taking amoxicillin, an antibiotic commonly found in pharmaceutical waste, as the model system, better removal was observed for silica-iron oxide nanocomposite with a more extended open shell structure.

    BACKGROUND: Ragged placental membranes is a distinct entity from retained placenta and not uncommonly reported in midwifery texts. Although the incidence of postpartum endometritis is merely 1-5% after vaginal births, it remains the most common source of puerperal sepsis, contributing up to 15% of maternal mortality in low income countries. Geographically-remote centres in Malaysia prophylactically administer antibiotics for women with ragged placental membranes after vaginal birth, extrapolating evidence from retained placenta. We sought to clarify the rationale in continuing such practices.

    METHODS: This was an open-label, prospective, multicentre, randomized trial. Three hospitals where the current protocol was to administer prophylactic amoxycillin-clavulanic acid served as the sites of recruitment. Women who delivered vaginally beyond 24+ 0 weeks of gestation with ragged membranes were invited to participate in the trial and randomized into prophylaxis or expectant management with medical advice by blocks of 10, at a 1:1 ratio. A medication adherence diary was provided and patients followed up at 2 weeks and 6 weeks postpartum.

    RESULTS: A total of 6569 women gave birth vaginally in three centres during the trial period, of which 10.9% had ragged membranes. The incidence of endometritis was not significantly raised in women with or without prophylaxis (0.90% vs 0.29%; p = 0.60). All cases of endometritis presented within the first 2 weeks and preventive use of antibiotics did not ameliorate the severity of endometritis since rates of ICU admission, surgical evacuation and transfusion were comparable.

    CONCLUSION: Preventive use of antibiotics after vaginal delivery in women with ragged placental membranes did not result in a reduction of endometritis. Educating women on the signs and symptoms of endometritis would suffice. Based on the reported incidence of ragged membranes, a change in practice would result in 1500 less prescriptions of antibiotics per annum in these three centres.

    TRIAL REGISTRATION: NCT03459599 (Retrospectively registered on 9 March 2018).

    BACKGROUND: Excessive and inappropriate antimicrobial use in the community is one risk factor that can result in the spread of antimicrobial resistance. Upper respiratory tract infections are most frequently reported among children and mainly of viral origin and do not require antibiotics. We have conducted Knowledge, Attitude and Perception (KAP) survey of parents to explore the parent's knowledge, attitude & perception of Saudi parents.

    METHODS: A knowledge attitude perception questioner was adopted from a previous study conducted in Greece by Panagakou et al. Raosoft online sample size calculator calculated the sample size by adding the total estimated Makkah population of 5,979,719 with a response rate of 30%, 5% margin of error and 99% confidence interval. Based on the described criteria five hundred & fifty-eight was the required sample size of the study. Incomplete questioners were excluded from the statistical analysis. SPSS version 21 was used to analyse data and to produce descriptive statistics.

    RESULTS: Most of the mothers (95%) responded among parents. 67% had no health insurance to cover medications costs. Most of them (74%) were related to medium income level. Seventy per cent of the parents believed physicians as a source of information for judicious antibiotics use. Interestingly, only 8% were agreed that most of the upper respiratory tract infections are caused by viral reasons. Majority of Saudi parents (53%) expect pediatricians to prescribe antimicrobials for their children for symptoms like a cough, nose discharge, sore throat and fever. Moreover, most the parents had the poor knowledge to differentiate commonly used OTC medications for URTI and antibiotics like Augmentin (Co-amoxiclav), Ceclor (cefaclor) and Erythrocin (Erythromycin). While comparing males and female's knowledge level, few males have identified Amoxil (Amoxicillin). Similarly, parents of age 20-30 years have good knowledge about the antibiotics.

    CONCLUSIONS: Majority of Saudi parents believe in pediatricians and use antibiotics on physician's advice. Most of them expect antibiotics from their physicians as a primary treatment for upper respiratory tract infections. There is need for more educational activities to parents by the pharmacists to prevent antibiotics overuse among children.

    BACKGROUND: Multidrug-resistant Helicobacter pylori strains are emerging in Southeast Asia. This study evaluates the region's real-world practice in H. pylori management.

    MATERIALS AND METHODS: Physicians who managed H. pylori eradication in daily practice across 10 Southeast Asian countries were invited to participate in an online questionnaire, which included questions about the local availability of antimicrobial susceptibility tests (ASTs) and their preferred eradication regimens in real-world practice. An empiric regimen was considered inappropriate if it did not follow the local guidelines/consensus, particularly if it contained antibiotics with a high reported resistance rate or was recommended not to be empirically used worldwide.

    RESULTS: There were 564 valid responses, including 314 (55.7%) from gastroenterologists (GIs) and 250 (44.3%) from non-GI physicians. ASTs were unavailable in 41.7%. In countries with low and intermediate clarithromycin resistance, the most common first-line regimen was PAC (proton pump inhibitor [PPI], amoxicillin, clarithromycin) (72.7% and 73.2%, respectively). Regarding second-line therapy, the most common regimen was bismuth-based quadruple therapy, PBMT (PPI, bismuth, metronidazole, tetracycline) (50.0% and 59.8%, respectively), if other regimens were used as first-line treatment. Concomitant therapy (PPI, amoxicillin, clarithromycin, metronidazole) (30.5% and 25.9%, respectively) and PAL (PPI, amoxicillin, levofloxacin) (22.7% and 27.7%, respectively) were favored if PBMT had been used as first-line treatment. In countries with high clarithromycin resistance, the most common first-line regimen was PBMT, but the utilization rate was only 57.7%. Alarmingly, PAC was prescribed in 27.8% of patients, ranking as the second most common regimen, and its prescription rate was higher in non-GI physicians than GI physicians (40.1% vs. 16.2%, p

    BACKGROUND:
    H. pylori eradication failures are difficult to treat and rescue therapies often consist of complex treatment regimens.

    AIM:
    To determine an effective and practical rescue therapeutic strategy for H. pylori treatment failures using two consecutive regimens: first rescue therapy - rabeprazole 20 mg t.d.s. and amoxicillin 1 g t.d.s. for 2 weeks and for failures a further second rescue therapy - rabeprazole 20 mg b.d., levofloxacin 500 mg b.d., amoxicillin 1 g b.d. for a further 2 weeks.

    METHODS:
    Consecutive patients who failed the proton pump inhibitor (PPI) 1-week triple therapy were recruited for the study. H. pylori status was determined by a C(13) urea breath test.

    RESULTS:
    One hundred and forty-nine patients received the first rescue therapy. Seven were not compliant to medication/defaulted follow-up. Eradication success- first rescue therapy: per protocol (PP) analysis-107/142 (75.4%) (95% CI (68.3-82.4%) and intention to treat (ITT) analysis-107/149 (71.8%) 95% CI (64.6-79.0%). Thirty-one of 35 patients who failed the first rescue therapy received the second rescue therapy. All were compliant with medications. Eradication success- PP and ITT was 28/31 (90.3%) 95% CI (74.2-98.0%). The cumulative eradication rate using both rescue therapies: PP analysis- 135/138 (97.8%) 95% CI: (93.8-99.6%), ITT analysis- 135/149 (90.6%) 95% CI: (84.7-94.8%).

    CONCLUSIONS:
    A 2-week high dose PPI-amoxicillin dual therapy followed by a PPI-amoxicillin-levofloxacin triple therapy were highly successful in achieving eradication in H. pylori treatment failures.

    OBJECTIVE:
    To re-examine the efficacy and tolerability of 1-week proton pump inhibitor triple therapy as a first-line Helicobacter pylori (H. pylori) eradication therapy.

    METHODS:
    Consecutive participants with a positive rapid urease test during an outpatient upper endoscopy were included. All participants were given pantoprazole 40 mg b.i.d., amoxycillin 1 g b.i.d. and clarithromycin 500 mg b.i.d. for 1 week. They were asked to return after 1 week to report any side effects related to the medications and to check for compliance. Successful eradication was defined by negative (13)C-urea breath test at least 4 weeks after the completion of therapy.

    RESULTS:
    A total of 191 patients were recruited into the study, of whom 81 were male (42.4%) and 110 female (57.6%), with a mean age of 55.6 (range 21-88) years. Overall 26 patients (13.6%) defaulted follow up and five patients were not compliant (taking less than 85%) with the medications. Per-protocol and intention-to-treat eradication rates were 84.4% (95% CI: 78.6-89.9%) and 71.2% (95% CI: 64.5-77.6%), respectively. Overall 68 participants (42.5%) reported no side effects, followed by 58 (36.3%) with a taste disturbance, 16 (10.0%) with epigastric pain, 15 (9.4%) with diarrhea, 13 (8.1%) with nausea or vomiting, 12 (7.5%) with loss of appetite, nine (5.6%) with dizziness and two (1.3%) with an allergic skin rash, none of which was severe.

    CONCLUSION:
    The current regime using pantoprazole, amoxycillin and clarithromycin is highly tolerable and effective and should continue to be recommended as a first-line therapy for H. pylori eradication in our setting.
