The Emergence, Persistence, and Dissemination of Antimicrobial-Resistant Bacteria in Environmental Hajj Settings and Implications for Public Health

Systematic review of multidrug-resistant Klebsiella pneumoniae in the Arabian Peninsula: molecular epidemiology and resistance patterns

Background

The rapid emergence of multidrug-resistant Klebsiella pneumoniae (MDR K. pneumoniae) is a major public health and economic burden worldwide. Various resistance mechanisms complicate treatment, leading to increased morbidity and mortality. Despite numerous studies conducted in Gulf Health Council (GHC) countries, the molecular epidemiology of MDR K. pneumoniae remains not clearly defined. This systematic review aims to analyze the emergence of antimicrobial resistance genes in MDR K. pneumoniae across GHC countries.

Methods

A systematic search was conducted using PubMed, ScienceDirect, and OpenMD for articles published up to March 15, 2023. The search strategy focused on the bacterial name, drug-resistance genotypes, and GHC countries. The review followed PRISMA guidelines, with two independent reviewers assessing the risk of bias using NIH Study Quality Assessment tools.

Results

The primary search yielded 1,663 studies, of which 67 met the inclusion criteria. Saudi Arabia contributed the most studies, with 41 (61.1%), followed by Kuwait with 7 (10.4%), and the UAE with 6 (9%) studies. Oman and Qatar each contributed 4 studies (6%), and Bahrain contributed three studies (4.5%). The remaining 4 studies (4.4%) were from multiple GHC countries. The studies exhibited considerable heterogeneity in detection methods, target genes, and resistance mechanisms. Notably, only one environmental study was conducted in the UAE, and one community-based study in Kuwait, while the remaining studies focused on clinical samples. Various resistance mechanisms and patterns were observed between countries and across different years within the same country. The review highlighted the widespread prevalence of ESBL genes, particularly bla TEM and bla CTX-M-15, and the emergence of carbapenemase genes such as bla OXA-48 and bla NDM-1 and bla KPC-2. Additionally, colistin resistance through the mcr-1 gene and mgrB mutations was reported in Saudi Arabia and the UAE, posing a significant public health challenge.

Conclusion

Data from GHC countries shows significant gaps, particularly in community and environmental and molecular epidemiology studies. Limited molecular and genome-based investigations hinder comprehensive AMR surveillance. Implementing standardized methodologies and fostering molecular and genome-based AMR surveillance programs at both national and regional levels within the GHC are essential for effectively combating the spread of MDR K. pneumoniae and improving public health outcomes in the region.

Perceived Knowledge, Guidelines Concordance, and Practices of Physicians for Management of Recurrent Urinary Tract Infections in Women

Background

Recurrent urinary tract infections (rUTIs) are common complaints that burden the healthcare system. Reporting perceived knowledge and guidelines in concordance regarding the management of (rUTI) is essential for providing better healthcare and higher treatment rate. This study assesses the perceived knowledge, guidelines concordance, and physicians' practices toward treatment of (rUTI) among physicians with different specialties.

Study Design

This questionnaire-based survey included residents, fellows, and consultants of various specialties across several regions in Saudi Arabia.

Results

A total of 419 physicians were included in the final analysis. In terms of age distribution, the majority were 28-38 years of age (159, 37.9%), followed by 18-28 years (99, 23.6%). Gender distribution was nearly balanced. The sample included a significant number of residents (182, 43.4%), consultants (173, 41.3%), and fellows (64, 15.3%). OBS/GYNE shows a significant presence of females (40.6%) and is notably represented in private hospitals or clinics (52.5%) and among fellows (40.6%) and consultants (32.4%). Infectious disease physicians had the highest perceived knowledge scores (3.83 ± 0.09), followed closely by urologists/urogynecologists (3.67 ± 0.48). Urologists/urogynecologists also reported the highest satisfaction (4.24 ± 0.83) and familiarity (2.89 ± 1.11) with new rUTI guidelines. Infectious disease physicians were most confident (3.50 ± 0.71) in communicating with patients about rUTI treatment options. In terms of practices and guideline adherence, obstetricians/gynaecologists were more likely to repeat urine sample tests for suspected contamination (3.73 ± 1.00) and less likely to treat asymptomatic bacteriuria (1.33 ± 0.59) the same as UTIs compared to other physicians. They also scored highest in conducting post-treatment tests for asymptomatic patients (3.21 ± 1.37) and recommending vaginal estrogen therapy for peri- and post-menopausal women to prevent UTIs (3.59 ± 1.06) among all specialties. Conversely, urologists and urogynecologists were more likely to discuss antibiotic prophylaxis (3.79 ± 0.89) and cranberry prophylaxis (3.71 ± 0.73) with their rUTI patients.

Conclusion

The findings highlight variations in knowledge, satisfaction, familiarity with guidelines, confidence in communication, and guideline concordance among different physician specialities regarding the management of UTIs and rUTIs.

Meningococcal Disease and Immunization Activities in Hajj and Umrah Pilgrimage: a review

Invasive meningococcal disease (IMD) outbreaks associated with Hajj and Umrah pilgrimage events in the Kingdom of Saudi Arabia (KSA) are well recognized. Past outbreaks have been associated with substantial intercontinental spread of specific Neisseria meningitidis serogroups. The emergence of meningococcal serogroup W (MenW) was a global concern following the 2000/2001 Hajj outbreaks. Broader compulsory meningococcal serogroups A, C, W and Y (MenACWY) immunization strategies for pilgrims were introduced in response to these events and led to substantial declines in IMD cases associated with these mass gatherings. However, there remains potential for future outbreaks either within KSA during the Hajj or in local populations via pilgrim meningococcal transmission on their return. While the annual Hajj involves pilgrims from over 185 countries, two-thirds of these arrive from 13 countries, chiefly from across South-East Asia, the Middle East and North African (MENA) regions; for which we review the relevant epidemiology of IMD and meningococcal carriage. While disease surveillance is limited and data are often lacking, MenB is an important serogroup associated with IMD and carriage in a number of countries. Available literature suggests that most pilgrims receive polysaccharide MenACWY vaccines (which do not impact carriage and onward transmission) and incomplete compliance with visa/entry immunization regulations is reported. Existing preventative approaches for visiting pilgrims require continued oversight. More complete compliance and switching to the conjugated MenACWY vaccine can provide more robust and broader protection for pilgrims. Additional immunization options could also be considered.

Status of infectious disease content in the professional pharmacy curriculum in Saudi Arabia: Results of a national survey

Objectives

Antimicrobial resistance is one of the main global problems faced by healthcare institutions. Healthcare professionals as service providers must have a basic understanding of this emerging threat; additionally, considering the evolving role of pharmacists in both the community and hospital setting, it is crucial that pharmacists are part of the fight against this threat. Therefore, this study aimed to assess infectious disease subjects covered in the pharmacy curriculum in Saudi Arabia, to evaluate teaching and knowledge assessment strategies concerning infectious diseases, and to explore challenges faced by faculty members in teaching infectious disease courses.

Methods

We constructed a questionnaire with 26 items and sent it to infectious disease faculty members at 26 Saudi Arabian pharmacy colleges. It included questions regarding the faculty and institution, infectious disease topics, hours dedicated to each topic, and tools and strategies used in the courses for better understanding and assessment of students. In addition, we enquired about the faculty members' current satisfaction of, and future plans for, the curriculum.

Results

The questionnaire was completed by infectious disease faculty members, department chairs, or college deans. Among the respondent schools, 85.5% were governmental and 14.5% were private institutions. The majority of colleges (98.2%) followed a semester format schedule, with 67.3% offering solely the Doctor of Pharmacy (PharmD) program. More than 78% of respondents covered all tier 1 infectious disease topics from the American College of Clinical Pharmacy Pharmacotherapy Didactic Curriculum Toolkit. The main tool used for teaching was lectures (94.5%), while patient case application was the main teaching strategy (54.5%). Approximately 63% of respondents thought that the curricula were adequate when they were asked about their opinion of the curricula coverage, and 63.64% thought that the curriculum provided adequate baseline knowledge on infectious diseases for the following 5 years.

Conclusions

The study revealed variations in infectious disease topics covered and the time dedicated to them among pharmacy colleges in Saudi Arabia. The faculty members who responded to our questionnaire were generally satisfied with their infectious disease curriculum. To the best of our knowledge, this is the first study to assess infectious disease curricula among Saudi pharmacy colleges. Thus, the findings of this study may encourage faculty members to advocate for the standardization of infectious disease courses offered at Saudi Arabian pharmacy colleges.

Antibiotic Use and Resistance Knowledge: Awareness Among the General Public in Jazan, Saudi Arabia

Background and objective: Antibiotics (Abs) are a class of medication generally prescribed for bacterial infections. Abs misuse, caused by either medication non-compliance or self-medication, may lead to Abs resistance, a problem that is trending around the globe. In 2018, dispensing Abs without a prescription became prohibited in Saudi Arabia. This study aimed to evaluate knowledge and attitude toward Abs use and resistance in Jazan Province.

Materials and methods: A cross-sectional study was conducted in the population of Jazan, using a self-administered electronic questionnaire to assess the knowledge and attitude toward Abs use and resistance and its related factors.

Results: According to our findings, 543 participants responded and most of the participants use Abs with a prescription (n = 280; 75%). About 40% identified correctly that Abs can treat only bacteria, not viruses, and 44% denied that Abs can treat all coughs and common cases. Then, regarding the knowledge about resistance, we found that those who had heard about Abs resistance represented more than half of the participants (56%), and had better knowledge about Abs use. Further, more than half of those who have heard about Abs resistance correctly defined the antibiotic susceptibility test, and about two-thirds were able to answer the related questions about Abs resistance.

Conclusion: To conclude, a positive correlation was found between knowledge about Abs resistance and Abs use. Thus, national Abs regulations and policies with continuous education and awareness must be continued to ensure a better understanding of Abs use.

Public knowledge, attitude and practice towards antibiotics use and antimicrobial resistance in Saudi Arabia: A web-based cross-sectional survey

Background: Antimicrobial resistance is a global issue that causes significant morbidity and mortality. Therefore, this study aims to assess knowledge, attitudes, and practices (KAP) of the general Saudi populations toward antibiotics use.

Design and method: A cross-sectional, anonymous online survey was conducted from January 1 to May 11, 2020, across five major regions of Saudi Arabia. Participants (aged ≥18 years) were invited through social media to complete an online self-structured questionnaire. All data were analyzed by Statistical Package (SPSS v. 25). Descriptive statistics, Pearson’s Chi-squared, t-tests, one-way analysis of variance (ANOVA), and Pearson correlation analyses were conducted.

Results: Out of 443 participants, the majority (n=309, 69.8%) were females, 294 (64.4%) were married, 176 (39.7%) were 25-34 years of age, 338 (76.3%) were living in the Eastern Province, 313 (70.7%) had college or higher education, 139 (31.4%) were not working, and 163 (36.8%) had a monthly income of USD 800-1330. Overall, most participants demonstrated good knowledge and practice (88% and 85.6%, respectively). However, 76.8%had inadequate attitude score levels towards antibiotics use. Of all the respondents, 74.9% knew that not completing a full course of antibiotics may cause antibiotics resistance, 91.33% did not agree that antibiotics should be accessed without a prescription, and 94.04% will not hand over leftover antibiotics to family members. Factors associated with adequate knowledge were female, medical jobs, and higher income (p<0.05).

Conclusions: Our findings revealed that while most participants were aware of antibiotics use and demonstrated good knowledge, good practices, they had negative attitudes towards antibiotics use.
