Antibiotic resistance before, during, and after the COVID-19 pandemic: a retrospective study.

INTRODUCTION: Prevalence of antibiotic resistance (AR) during the coronavirus 2019 (COVID-19) pandemic was higher than pre-pandemic times. This study determined the prevalence and patterns of AR among Gram-positive and negative bacteria before, during and after COVID-19 in Saudi Arabia and identified the associated factors. METHODOLOGY: A retrospective cross-sectional study was employed to identify patients with positive AR bacteria between March 2019 and March 2022. The bacterial isolates and patients' data were identified from laboratory and medical records departments retrospectively. Binary logistic regression analysis was performed to identify the factors associated with AR and deaths. Multinominal logistic regression was applied to confirm the factors associated with AR classification. RESULTS: AR Gram-negative bacteria decreased during and after the pandemic. However, S. aureus showed a negligible increase in resistance rate after pandemic, while E. faecium, recorded a higher-than-average resistance rate during the pandemic. The prevalence of pan drug resistance (PDR) during the pandemic (85.7%) was higher than before (0%) and after (14.3%), p = 0.001. The length of stay and time were significant predictors for AR classification. The odds of multi drug resistance (MDR) development to PDR during the pandemic were 6 times higher than before and after (OR = 6.133, CI =, p = 0.020). Age, nationality, COVID-19 infection, smoking, liver disease, and type and number of bacteria were associated with death of patients with positive AR. CONCLUSIONS: Further studies are recommended to explore the prevalence of PDR and to justify the increased rates of E. faecium AR during the COVID-19 pandemic.

Five-year species distribution and antimicrobial susceptibility of non-tuberculous mycobacteria in Malaysia, 2018-2022.

Introduction. Non-tuberculous Mycobacteria (NTM) is a group of mycobacteria distinct from the Mycobacterium tuberculosis complex. They can cause opportunistic infections, especially in immunocompromised individuals.Gap Statement. Over the last few years, there has been a growing concern regarding the distribution and antimicrobial resistance of NTM in Malaysia. however, a comprehensive study to fully grasp the NTM situation has yet to be conducted.Aim. This study aimed to investigate the species distribution and antimicrobial susceptibility patterns of NTM isolated from clinical samples in Malaysia from 2018 to 2022.Methodology. A retrospective analysis was conducted on NTM isolates obtained from various clinical specimens over a span of five years. The isolates were identified using phenotypic and molecular techniques, and antimicrobial susceptibility profiles for clinically significant isolates were determined using minimum inhibitory concentration.Results. The study revealed a diverse distribution of NTM species in Malaysia, with Mycobacteroides abscessus complex and Mycobacterium avium complex emerging as the most predominant. Furthermore, the antimicrobial susceptibility patterns showed varying degrees of resistance to commonly used antibiotics, highlighting the significance of treatment tailored to susceptibility testing results.Conclusion. This study provides valuable perspective into the epidemiology of NTM in Malaysia. The information gained from this study should prove useful for empirically treating serious NTM infections prior to species identification and the availability of antimicrobial susceptibility testing results.

Anti-S Antibodies Against SARS-CoV-2 Infection Among Four Types of Vaccines in Malaysia.

Monitoring SARS-CoV-2 antibody levels can provide insights into a person's immunity to COVID-19 and inform decisions about vaccination and public health measures. Anti-S may be useful as an indicator of an effective immune response. Thus, we conducted this study that aimed to determine the immune response of anti-S antibodies against SARS-CoV-2 for all the vaccine types over time among adult recipients in Malaysia and to determine the associated factors. This study was a cohort that recruited 2513 respondents aged 18 years and above from June to December 2021. Each participant was followed-up for 1-year period from the initial vaccine dose (baseline). We found that the anti-S antibody generally increased for all vaccine types and peaked at two weeks after the second dose vaccination, with Pfizer recipients having the highest median of 100 (100.00-100.00). During the third-month follow-up, the seropositivity of anti-S antibody and the median level decreased for all vaccines. We found that type of vaccines, comorbid status, infection, and booster status were significantly associated with the anti-S antibody level after one year.

Healthcare commissioners' experience with antibiotic resistance during the COVID-19 pandemic in Saudi Arabia: a qualitative study.

Introduction: The occurrence of antibiotic resistance (AR) has become a critical issue during the Novel coronavirus disease 2019 (COVID-19) pandemic. This study explores the experiences of healthcare commissioners with AR during the COVID-19 pandemic, identifies challenges, and provides recommendations for combating AR during pandemics. Methods: This qualitative study was multi-centered and used a phenomenological approach. Semi-structured interviews were conducted between December 2022 and January 2023 among 11 health commissioners using video calls. Results: Seven themes emerged from the data, including knowledge of AR and its consequences, the antibiotic prescription system, the future of AR and potential contributory factors, the impact of COVID-19 on AR and their relationship, the experience of AR during the COVID-19 pandemic in healthcare facilities, barriers that prevent the misuse of antibiotics during pandemics, and recommendations regarding antibiotic resistance during pandemics. Conclusion: The findings of this study could be used to inform policy and practice for government healthcare workers (HCWs) and the public. Furthermore, this study identified the main challenges of AR during the pandemic, and the recommendations of health commissioners were provided accordingly. Such recommendations could be beneficial on a national and international scale to reduce the impact of future pandemics on AR.

Knowledge, attitude and practice of healthcare workers towards antibiotic resistance during the COVID-19 pandemic.

Background: During the novel Coronavirus 2019 (COVID-19) outbreak, there was an overuse of antibiotics in hospitals. The improper use of antibiotics during COVID-19 has increased antibiotic resistance (AR), which has been reported in multiple studies. Objectives: To assess the healthcare workers' (HCWs) knowledge, attitude and practice (KAP) in relation to AR during the era of COVID-19, and identify the associated factors with good knowledge, positive attitude and good practice. Methods: A cross-sectional design was used to assess the KAP of HCWs in Najran, Kingdom of Saudi Arabia (KSA). A validated questionnaire was used to collect participants' data, which consisted of the following information; socio-demographics, knowledge, attitude and items for practice. Data were presented as percentages and median (IQR). Mann-Whitney and Kruskal Wallis tests were used to compare them. Logistic regression was used to identify the associated factors linked to KAP. Results: The study included 406 HCWs. Their median (IQR) knowledge score was 72.73% (27.27%-81.82%), attitude score was 71.43% (28.57%-71.43%) and practice score was 50% (0%-66.67%). About 58.1% of the HCWs stated that antibiotics could be used to treat COVID-19 infection; 19.2% of the participants strongly agreed and 20.7% agreed that during the COVID-19 pandemic, antibiotics were overused at their healthcare institutions. Only 18.5% strongly agreed and 15.5% agreed when asked whether antibiotics used properly for the right indication and duration can still result in AR. The significantly associated factors with good knowledge were nationality, cadre and qualification. A positive attitude was significantly associated with age, nationality and qualification. Good practice was significantly associated with age, cadre, qualification and working place. Conclusion: Although the HCWs had a positive attitude regarding AR during COVID-19, their knowledge and practice need significant improvement. Implementation of effective educational and training programmes are urgently needed. In addition, further prospective and clinical trial studies are needed to better inform these programmes.

Antibiotic Resistance during COVID-19: A Systematic Review.

One of the public health issues faced worldwide is antibiotic resistance (AR). During the novel coronavirus (COVID-19) pandemic, AR has increased. Since some studies have stated AR has increased during the COVID-19 pandemic, and others have stated otherwise, this study aimed to explore this impact. Seven databases-PubMed, MEDLINE, EMBASE, Scopus, Cochrane, Web of Science, and CINAHL-were searched using related keywords to identify studies relevant to AR during COVID-19 published from December 2019 to May 2022, according to PRISMA guidelines. Twenty-three studies were included in this review, and the evidence showed that AR has increased during the COVID-19 pandemic. The most commonly reported resistant Gram-negative bacteria was Acinetobacterbaumannii, followed by Klebsiella pneumonia, Escherichia coli, and Pseudomonas aeruginosa. A. baumannii and K. pneumonia were highly resistant to tested antibiotics compared with E. coli and P. aeruginosa. Moreover, K. pneumonia showed high resistance to colistin. Commonly reported Gram-positive bacteria were Staphylococcus aureus and Enterococcus faecium. The resistance of E. faecium to ampicillin, erythromycin, and Ciprofloxacin was high. Self-antibiotic medication, empirical antibiotic administration, and antibiotics prescribed by general practitioners were the risk factors of high levels of AR during COVID-19. Antibiotics' prescription should be strictly implemented, relying on the Antimicrobial Stewardship Program (ASP) and guidelines from the World Health Organization (WHO) or Ministry of Health (MOH).

Tuberculosis Treatment Outcome in Patients with TB-HIV Coinfection in Kuala Lumpur, Malaysia.

BACKGROUND: Tuberculosis (TB) is a serious health threat to people living with human immunodeficiency virus (HIV). This study aimed to identify the characteristics, unsuccessful TB treatment rate, and determinants of unsuccessful TB treatment outcome among patients with TB-HIV coinfection in Kuala Lumpur. METHODS: This was a cross-sectional study. The data of all patients with TB-HIV in the federal territory of Kuala Lumpur from 2013 to 2017 were collected and reviewed. The data were retrieved from the national database (TB Information System) at the Kuala Lumpur Health Department from 1 March 2018 to 31 May 2018. RESULTS: Out of 235 randomly selected patients with TB-HIV, TB treatment outcome was successful in 57.9% (cured and completed treatment) and unsuccessful in 42.1% (died, failed, or lost to follow-up). Patients who did not receive DOTS (directly observed treatment, short course) (adjusted odds ratio: 21.71; 95% confidence interval: 5.36-87.94) and those who received shorter treatment duration of <6 months (aOR: 34.54; 95% CI: 5.97-199.93) had higher odds for unsuccessful TB treatment outcome. CONCLUSIONS: Nearly half of the patients with TB-HIV had unsuccessful TB treatment outcome. Therefore, it is important to ensure that such patients receive DOTS and continuous TB treatment of >6 months. It is crucial to strengthen and widen the coverage of DOTS, especially among high-risk groups, in healthcare settings. Strict follow-up by healthcare providers is needed for patients with TB-HIV to gain treatment adherence and for better rates of successful TB treatment.

Factors associated with tuberculosis disease among children who are household contacts of tuberculosis cases in an urban setting in Malaysia.

BACKGROUND: With the rise in prevalence of childhood tuberculosis (TB) globally, contact tracing should be a powerful strategy for early diagnosis and management, especially in children who are household contacts of active TB cases. Here, we aimed to determine the prevalence and factors associated with TB disease in children who are household contacts of TB cases. METHODS: We used a cross-sectional study with data from the Malaysian TB Information System (TBIS) recorded from 1 January 2014 to 31 December 2017. All children aged 0-14 years who were registered in the TBIS with at least one household contact of TB cases were included in the study. Multiple logistic regression analysis was performed to calculate the adjusted odds ratio (adj. OR) and for adjusting the confounding factors. RESULTS: A total of 2793 children were included in the study. The prevalence of active TB was 1.5% (95% confidence interval [CI]: 1.31, 1.77%). Children aged < 5 years [adj. OR 9.48 (95% CI: 3.41, 26.36) p < 0.001] with positive tuberculin skin test [adj. OR 395.73 (95% CI: 134.17, 1167.13), p < 0.001] and investigation period of > 6 weeks [adj. OR 7.48 (95% CI: 2.88, 19.43), p < 0.001] had significantly higher odds for TB disease. CONCLUSIONS: The prevalence of TB disease in children who were household contacts of TB cases is relatively low. However, contact tracing programmes should not only focus on children aged < 5 years and with positive tuberculin skin test results, but also be empowered to reduce the investigation period.

The Effectiveness of Breastfeeding Intervention on Breastfeeding Exclusivity and Duration among Primiparous Mothers in Hospital Universiti Sains Malaysia

Background: In Malaysia, the rates of mothers practising breastfeeding exclusively among babies at six months of age still do not achieve the Global Nutritional Targets 2025 which is 50%. Objective: To determine the effectiveness of breastfeeding intervention in improving breastfeeding outcomes. Method: A quasi-experimental design was used involving a purposive sample of 96 primigravidas (intervention group (IG) = 48, control group (CG) = 48) recruited at Hospital USM. Data were collected using the Breastfeeding Assessment Questionnaire. Mothers in IG received the current usual care and two hours of an additional education programme on breastfeeding, breastfeeding booklet, notes from the module, and postnatal breastfeeding support in the first week of postpartum. Mothers in CG received the current usual care only. The mothers were assessed on the first and sixth week and then the fourth and sixth month of postpartum. Results: The results indicated that there was a statistically significant difference between the groups on the fourth month postpartum (X2 = 5.671, P = 0.017) in practicing full breastfeeding. The breastfeeding duration rates of the IG were longer than those of the CG. However, the results showed only two follow-up weeks that were significant (week 6, X2 = 5.414, P = 0.020, month 4, X2 = 7.515, P = 0.006). There was a statistically significant difference between IG and CG as determined by one-way ANCOVA on the breastfeeding duration after controlling age and occupation, F (3, 82) = 6.7, P = 0.011. The test revealed that the breastfeeding duration among IG was significantly higher (20.80 ± 6.31) compared to CG (16.98 ± 8.97). Conclusions: Breastfeeding intervention can effectively increase breastfeeding duration and exclusivity outcomes among primiparous mother
