Potency of commonly retailed antibiotics in pharmacies found in Adama, Oromia regional state, Ethiopia.

ABSTRACT:

Introduction

Antibiotics are commonly used for the treatment and prevention of bacterial infections. The potency of antibiotics can be affected by factors such as temperature, light, moisture, and storage conditions. Inappropriate storage and transportation of antibiotics may lead to loss of potency earlier than the expiry date. The aim of this study was to determine the potency and associated factors of commonly retailed antibiotics.

Method

Institution-based cross-sectional study was conducted on commonly retailed antibiotics in pharmacies that are available in Adama, Ethiopia from March 2018 to June 2018. This study focused on commonly ordered antibiotics such as amoxicillin, azithromycin, ciprofloxacin, and ceftriaxone. Antibiotics to be tested were selected by using a simple random sampling technique. Socio-demographic and related data were collected using a semi-structured questionnaire. Antibiotic susceptibility testing was performed using the disc diffusion method as described in the Clinical Laboratory Standard Institute guideline.

Results

Mean inhibition zones of amoxicillin, ciprofloxacin, azithromycin, and ceftriaxone were 14.2 ± 4 mm, 30.9 ± 4.2 mm, 17.47 ± 3.83 mm, and 32.7±1.8 respectively. Out of 164 antibiotics tested, 61% passed the potency test. The potency of antibiotics varies across different countries in which 53.7% and 54.6 of antibiotics from India and Ethiopia passed the potency test. All ceftriaxone tested in this study passed the potency test. Factors such as air condition of pharmacy (X2 = 4.27; p = 0.039), source of all antibiotics (X2 = 5.41; p = 0.02), and source of amoxicillin (X2 = 4.73; p = 0.03) were significantly associated with potency of antibiotics.

Conclusions

About 40% of antibiotics tested in the current study did not pass the potency test; this warrants further investigation to identify the magnitude of the problem and its causes at a large scale.

Project description:BackgroundAzithromycin is a therapeutically" relevant macrolide antibiotic registered on the Essential Medicines List of the World Health Organization. The fact that medicine is selected as an essential drug doesn't mean that it is of good quality. Hence, a continuous quality evaluation of the drug should be mandated to verify that the right medication is available on the market.ObjectiveTo evaluate the quality of Azithromycin Tablets commonly marketed in Adama, and Modjo town, Oromia Regional State, Ethiopia.MethodsAll six brands were subjected to in-vitro quality control tests, which were carried out according to procedures described in the manufacturer's method, the United States Pharmacopeia, and the WHO inspection tool. All quality control parameters were compared by one-way ANOVA. Statistically, significant difference was considered when P<0.05. The in-vitro dissolution profiles of the brands were also compared statistically using the post-hoc Dunnett test, model-independent and model-dependent approaches.ResultsAll of the evaluated brands agreed with WHO visual inspection criteria. All of the tablets achieved the thickness, and diameter test requirements of the manufacturer's specification (±5%). All brands passed the hardness, friability, weight variation, disintegration, identity, and assay tests as stipulated by USP. The dissolution rate was more than 80% in 30 minutes, which was within the USP specification. The model-independent parameters have confirmed that only two brands (2/6) were deemed better brands for interchangeability. Weibull and Korsemeyer's Peppas model were the best release models.ConclusionAll of the evaluated brands passed the quality specification. The model dependent approaches revealed that drug release data fit well to the Weibull, and Korsemeyer's Peppas release models. However, the model-independent parameters have confirmed that only two brands were deemed better brands (2/6) for interchangeability. Due to the dynamic nature of low-quality medications, the Ethiopian Food, and Drug Authority should keep an eye on marketed products to guarantee their quality, especially for drugs like azithromycin for which non-bioequivalence data from the study has revealed a clinical concern.

Project description:A survey was undertaken from December 2017 to April 2018 to assess the biosecurity status of 44 commercial chicken farms established in Bishoftu town, Ethiopia, by interviewing farm owners using a structured questionnaire. The obtained data were summarized using frequency tables and analyzed with Pearson's chi-square test and Fischer's exact value using Stata 14 statistical software. From the assessed chicken farms, 31 (70.45%) were located within 0-50 m from the main road, 39 (88.64%) situated 500 m from the nearest farms, and 27 (61.36%) placed within 0-20 m from the residential areas. Forty-one (93.18%) participants disclosed that their employees did not receive training on biosecurity. From the assessed chicken farms, 30 (68.18%) had fences, 40 (90.91%) had footbaths at their gates, 31 (70.45%) prohibited visitors entrance, and 39 (88.64%) did not exchange equipment with other farms. In addition, 26 (59.09%) farms were easily accessed by wild birds, each of 42 (95.45%) farms purchased day-old chicks and feed, and 40 (90.91%) shared trucks with other farms as well. Among the assessed farms, only 2 (4.55%) had signages to restrict people's access, 9 (20.45%) had isolation rooms for diseased chickens, 14 (31.82%) disposed of dead birds properly, and 10 (22.73%) kept various types of records. Occupation (Fischer's exact value = 8.40; P=0.019), previous training (Fischer's exact value = 4.40; P=0.044), source of the premises (χ 2 = 5.50; P=0.019), and farm capacity (Fischer's exact value = 13.50; P=0.002) were found statistically significantly associated with the farm biosecurity status. The farm biosecurity status was found to be good in farms that were run by civil servants, had trained employees, are owned premises, and were of large and medium scales. In conclusion, the higher poor biosecurity status on chicken farms calls for the implementation of good biosecurity practices in each farm as well as the provision of training to the farm owners and their employees.

Project description:BackgroundOne of the major challenges in developing an effective vaccine against asexual stages of Plasmodium falciparum is genetic polymorphism within parasite population. Understanding the genetic polymorphism like block 2 region of merozoite surface protein-1 (msp-1) gene of P. falciparum enlighten mechanisms underlining disease pathology, identification of the parasite clone profile from the isolates, transmission intensity and potential deficiencies of the ongoing malaria control and elimination efforts in the locality. Detailed understanding of local genetic polymorphism is an input to pave the way for better management, control and elimination of malaria. The aim of this study was to detect the most frequent allelic variant of the msp-1 gene of P. falciparum clinical isolates from selected health facilities in Adama town and its surroundings, Oromia, Ethiopia.MethodsOne hundred thirty-nine clinical isolates were successfully amplified for msp-1 gene using specific primers. Nested PCR amplification was conducted targeting K1, MAD20, and R033 alleles followed by gel electrophoresis for fragment analysis. Based on the detection of a PCR fragment, infections were classified as monoclonal or multiple infections.Results19 different size polymorphism of msp-1 gene were identified in the study, with 67(48%) MAD20, 18 (13%) K-1 and 18 (13%) RO33 allelic family. Whereas, the multiple infections were 21(15%), 8 (5.8%), 4(2.9%), 3(2.2%) for MAD20 + K-1, MAD20 + RO33, K-1 + RO33, and MAD20 + K-1, RO33, respectively. The overall Multiplicity of infection (MOI) was 1.3 and the expected heterozygosity (He) was 0.39 indicating slightly low falciparum malaria transmission.ConclusionThe status of msp-1 allele size polymorphism, MOI and He observed in the study revealed the presence of slightly low genetic diversity of P. falciparum clinical isolates. However, highly frequent MAD20 allelic variant was detected from clinical isolates in the study area. Moreover, the driving force that led to high predominance of MAD20 allelic variant revealed in such malaria declining region demands further research.

Project description:BackgroundAdherence to preventive measures of Coronavirus disease 2019 (COVID-19) was among the means to tackle the transmission of the virus. However, reluctance to implement the recommended preventive measures has been reported to be a major problem everywhere including Oromia Regional State.PurposeThis research was aimed to assess the level of adherence to COVID-19 preventive measures and associated factors in the study area.Participants and methodsCommunity based cross-sectional study was conducted. Sample of 2751 adults aged ≥ 18 years were used for the quantitative study. Also, 20 FGDs and 30 KIIs were conducted in the qualitative approach. The collected data were entered into Epi info version 7.2.0.1 and analyzed using STATA 15. The qualitative data were entered into NVivo version 12 for its organization. Bivariate and multivariable binary logistic regression analyses were conducted to determine the association between the study variables. Odds Ratio with its 95%CI was calculated and P- Value < 0.05 was used as a cut off points to declare the significance.ResultsThe level of adherence to COVID-19 preventive measure was 8.3. Age [AOR, 4.00; 95% CI: 1.50, 10.45], Illiterate AOR, 0.38; 95% CI: 0.15, 0.93], read and write [AOR, 0.26; 95% CI: 0.10, 0.72], attended primary [AOR, 0.30; 95% CI: 0.13, 0.70], occupation (AOR; 95% CI: 0.29, 0.96] and knowledge [AOR, 0.20; 95% CI: 0.01, 0.11] were factors associated with level of adherence to COVID-19 preventive measures. Political context, unemployment, livelihoods, and social events were mentioned as reasons for the poor adherence to COVID-19 preventive measures.ConclusionsThe overall level of adherence to COVID-19 preventive measures in the study area was low. Age, level of education, occupation, and knowledge were factors associated with level of adherence to COVID-19 preventive measures. Activities to increase the adherence to COVID-19 preventive measures should be implemented by the concerned bodies.

Project description:BackgroundEven though health care seeking interventions potentially reduce child mortality from easily treatable diseases, significant numbers of children die without ever reaching a health facility or due to delays in seeking care in Ethiopia. This study aimed to assess health care seeking behavior for common childhood illnesses and associated factors.MethodsA community-based cross-sectional study was conducted in Jeldu District from January to February 2011. A systematic sampling method was used for sample selection. Data were collected from 422 caregivers with under-five children who experienced diseases within six weeks before the survey. Interviewer administered structured and pre-tested questionnaire which were used to collect data. Data entry and cleaning were carried out using Epi Info version 3.5.1 and analyzed using SPSS version 16. Descriptive analysis was done to determine the magnitude of health care seeking behavior. Multivariate logistic regression analyses were performed to identify associated factors.ResultsA total of 422 caregivers of under-five children were participated in the study giving an overall response rate of 97.5%. Three hundred fifteen (74.6%) children sought care from health facilities for all conditions. However, only 55.4% of them were taken to health facilities as first source treatment during their illness and prompt care was also very low (13.7%). Marital status of the caregivers (AOR = 2.84; 95%CI: 1.62-4.98), number of symptoms experienced by the child (AOR = 2.04; 95%CI: 1.24-3.36) and perceived severity of the illness (AOR = 3.20; 95%CI: 1.96-5.22) were predictors of health care seeking behavior.ConclusionHealth care seeking behavior for childhood illnesses was delayed and decision to seek care from health facilities was influenced by worsening of the illnesses. Thus, community level promotion of prompt health care seeking is essential to enhance the health care seeking behavior for child hood illnesses in the locality.

Project description:BackgroundUndernutrition is cellular imbalance between supply of nutrients, energy and body's demand to ensure growth, maintenance, and specific function. However, there was no study conducted earlier on this topic in East Borena Zone.ObjectiveTo assess the prevalence of undernutrition and associated factors among pregnant women in East Borena Zone, Liban District.MethodA community-based cross-sectional study was conducted on 420 study participants from November 20 to December 2021. The systematic sampling technique and simple random sampling methods were used to select study participants. Data were double entered into Epi-info software version 7 and SPSS version 21 software for analysis. Descriptive statistics were used to describe the characteristics of study participants. Bivariate and multivariable logistic regressions were carried out to identify the association between independent and dependent variables by measuring the adjusted odds ratio and 95% confidence interval. P-values less than 0.05 were considered statistically significant.ResultsPrevalence of undernutrition among pregnant women was about (44.9%) of family monthly income [AOR = 8.72 (4.80, 15.83)], women's decision-making autonomy [AOR = 0.40 (0.19, 0.82)], skipping meal [AOR = 2.62 (1.41, 4.89)], substance use [AOR = 2.01 (1.07, 3.77)], household food insecurity [AOR = 2.01 (1.06, 3.80)], lack of prenatal dietary advice [AOR = 2.73 (1.53, 4.89)], absence of household latrine [AOR = 9.23 (3.48, 24.46)], not participating health development army's meeting at village level [AOR = 3.01 (1.57, 5.72)] and hand washing habit [AOR = 6.55 (3.02, 14.20)] had shown statistically significant association with undernutrition.ConclusionThe prevalence of undernutrition among pregnant women was high income. Women's decision-making autonomy, skipping meals, substances use, household food insecurity, lack of prenatal dietary advice, poor hand washing habit, lack household of latrine, and not participation in health development army's meeting were found to be predictors of the undernutrition.
