Antimicrobial resistance in Streptococcus pneumoniae: a retrospective analysis of emerging trends in the United Arab Emirates from 2010 to 2021. Front Public Health 2023; 11:1244357. [PMID: 38074724 PMCID: PMC10702210 DOI: 10.3389/fpubh.2023.1244357] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Accepted: 10/24/2023] [Indexed: 12/18/2023] Open
Abstract
Introduction Although pneumococcal conjugate vaccines (PCV) have been effective in reducing the burden of Streptococcus pneumoniae infections, there is a paucity of data on the relationship with antimicrobial resistance (AMR) trends in the Arabian Gulf region. This study was carried out to assess S. pneumoniae resistance trends in the United Arab Emirates (UAE) where PCV-13 vaccination was introduced in 2011. Methods Retrospective analysis of S. pneumoniae demographic and microbiological data collected as part of the national AMR surveillance program from 2010 to 2021 was carried out. A survey of reporting sites and hand searching of annual reports of local health authorities was carried out to identify data on S. pneumoniae serotypes as this is not included in the AMR surveillance database. Results From 2010 to 2021, 11,242 non-duplicate S. pneumoniae isolates were reported, increasing from 324 in 2010 to 1,115 in 2021. Factoring in annual increment in the number of surveillance sites, the number of isolates per site showed an upward trajectory from 2015 to 2018 and declined in 2020 with the onset of the pandemic. The majority of isolates (n/N = 5,751/11,242; 51.2%) were from respiratory tract specimens with 44.5% (n/N = 2,557/5,751) being nasal colonizers. Up to 11.9% (n/N = 1,337/11,242) were invasive pneumococcal disease (IPD) isolates obtained from sterile site specimens including blood (n = 1,262), cerebrospinal (n = 52), pleural (n = 19) and joint (n = 4) fluid; and were predominantly from pediatric patients. The downward trend for amoxicillin and for penicillin G at the non-meningitis and meningitis as well as oral penicillin breakpoints was statistically significant. In contrast, increasing trends of resistance were seen for levofloxacin, moxifloxacin, trimethoprim/sulfamethoxazole and erythromycin. IPD and non-IPD isolates showed similar demographic and AMR trends. None of the surveillance sites carried out S. pneumoniae serotyping and handsearching of annual reports did not yield this information. Conclusion The increasing trend of pneumococcal disease and AMR with emergence of isolates with MDR phenotype despite is of concern. In the absence of S. pneumoniae serotyping the role of non-vaccine serotypes in driving this pattern remains unknown. There is an urgent need for serotype, genomic and AMR surveillance of S. pneumoniae isolates in the UAE.

A Systematic Review of Pneumococcal Carriage, Disease, Antimicrobial Resistance, and Vaccination in Egyptian Children Aged 18 Years and Younger. Infect Dis Ther 2021; 10:2119-2155. [PMID: 34468962 PMCID: PMC8408359 DOI: 10.1007/s40121-021-00523-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2021] [Accepted: 08/05/2021] [Indexed: 11/05/2022] Open
Abstract
Streptococcus pneumoniae remains an important bacterial pathogen, particularly for young children in low- and middle-income countries. A systematic review was conducted of peer-reviewed literature from PubMed published as of May 13, 2020, to identify articles relevant to invasive pneumococcal disease, pneumonia, otitis media (OM), nasopharyngeal carriage (NPC), antimicrobial resistance (AMR), and vaccination coverage in Egypt, with particular focus on children ≤ 18 years of age. A total of 16 relevant articles spanning three decades were included in this review. Among studies reviewed, S. pneumoniae was the causative agent of meningitis in 21–30% of cases among hospitalized children between 1983 and 2003. One study showed that serotypes 6A and 6B predominated among meningitis cases of pediatric patients aged < 5 years. This review also revealed that S. pneumoniae was the most commonly identified bacterial pathogen of acute mastoiditis, a severe complication of acute OM, among children aged 9 months to 11 years. NPC studies showed that approximately 30% of Egyptian children were carriers of S. pneumoniae. AMR, especially to penicillin, continues to be a growing concern in low- and middle-income countries, including among Egyptian children. Several predominant serotypes were identified to be associated with penicillin resistance, such as 6B, 1, 19A, 23F, and 6A. Currently available pneumococcal vaccines (PCVs) such as PCV10 and PCV13 may provide coverage against the most prevalent circulating serotypes among Egyptian children. Comprehensive disease surveillance and immunization programs are needed to ensure that this vulnerable population is sufficiently protected against pneumococcal disease.

Antibiotic Prescribing Patterns for Hospitalized children with Community-Acquired Pneumonia in a Secondary Care Center. J Infect Public Health 2021; 14:1035-1041. [PMID: 34166877 DOI: 10.1016/j.jiph.2021.05.018] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2020] [Revised: 04/17/2021] [Accepted: 05/30/2021] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND Narrow-spectrum antibiotics are recommended as the first-line therapy for management of children hospitalized with community-acquired pneumonia (CAP). There are limited data evaluating the antibiotic prescription patterns for CAP in Saudi Arabia. The goal of this study to report on the antibiotic patterns in children hospitalized with CAP. METHODS A prospective cross-sectional study was conducted in children aged 1 month to 13 years who were hospitalized with a diagnosis of CAP at King Khalid Hospital in Majmaah, Saudi Arabia, between January 2019 and January 2020. RESULTS Data from 233 patients were collected. The majority of patients received amoxicillin clavulanate (57.9%), followed by ceftriaxone (30%), azithromycin (20.6%), cefuroxime (6%), ampicillin (2.1%), and piperacillin-tazobactam (2.1%). None of our patients were started on narrow-spectrum therapy. The younger age group (1-3 months) and patients with severe pneumonia were more likely to receive broad-spectrum cephalosporin and have a longer hospital stay (P = .000 and P = .002, respectively). However, the 4 months to 5 years age group was more likely to receive amoxicillin clavulanate (P = .001). Male gender was a significate risk factor for patients with severe pneumonia (P=.013) CONCLUSIONS: We demonstrated the inappropriate use of broad-spectrum therapy in children hospitalized with CAP. Further large multicenter studies are necessary to evaluate the patterns of antibiotic use and implement antimicrobial stewardship programs or quality-improvement projects to improve adherence to guidelines.

Abstract
BACKGROUND Children with sickle cell disease (SCD) are particularly susceptible to pneumococcal infection. Administration of the 13-valent conjugate pneumococcal vaccine which is now available in Nigeria may help to reduce the incidence. OBJECTIVES To determine the serum level of pneumococcal-specific IgG (PIgG) in a cohort of patients with SCD after administration of a single-dose of a 13-valent pneumococcal conjugate vaccine. METHODS The study was conducted between December 2011 and March 2012 among children with SCD aged 5 months to 5 years attending the sickle cell clinic in five public hospitals in Lagos. Altogether, 151 children with SCD and 52 without it (controls) were recruited by convenience sampling from the sickle cell clinics and well-child clinics. Blood samples were collected for PIgG concentrations before and 2 months after a single dose of the Prevenar 13 vaccine. Seroconversion was defined as a fourfold or greater increase in antibody concentration after vaccination while those with PIgG concentrations ≥200 μU/ml were considered to have protective levels. RESULTS The age range of the total study group was 5-60 months with a mean (SD) of 39.04 (15.44) months and a median of 39 months. The mean (SD) ages of subjects with and without SCD were 38.91 (15.75) months and 16.39 (15.45) months, respectively. The PIgG concentration 2 months post-vaccination was significantly greater than the pre-vaccination levels in all age categories in both groups and almost all subjects had protective PIgG concentrations 2 months after vaccination. A four-fold increase in PIgG concentration was detected more commonly in the controls than in SCD patients. CONCLUSION Prevenar 13 provided protective immunity in all vaccinated children but those under 2 years of age who had non-protective levels pre-vaccination benefited the most.

Abstract
This systematic review evaluated the epidemiology of community-acquired pneumonia in children <6 y of age within 90 developing and newly industrialized countries. Literature searches (1990–2011), based on MEDLINE, EMBASE, Cochrane, CAB Global Health, WHO, UNICEF, country-specific websites, conferences, health-technology-assessment agencies, and the reference lists of included studies, yielded 8,734 records; 62 of 340 studies were included in this review. The highest incidence rate among included studies was 0.51 episodes/child-year, for children <5 y of age in Bangladesh. The highest prevalence was in Chinese children <6 months of age (37.88%). The main bacterial pathogens were Streptococcus pneumoniae, Haemophilus influenzae and Mycoplasma pneumoniae and the main viral pathogens were respiratory syncytial virus, adenovirus and rhinovirus. Community-acquired pneumonia remains associated with high rates of morbidity and mortality. Improved and efficient surveillance and documentation of the epidemiology and burden of community-acquired pneumonia across various geographical regions is warranted.

Abstract
OBJECTIVE This systematic review examined the epidemiology of otitis media (OM) in children <6 years within 90 developing and newly industrialised countries. METHODS Literature searches (1992-2011), based on MEDLINE, EMBASE, WHO, Index Medicus, country-specific websites, conferences, and the reference lists of included studies, yielded 11,413 records; 59 of 344 studies analysed were included in this review. RESULTS The majority of the identified studies provided only a single timepoint for OM. In children <6 years of age, OM prevalence was found to be 9.2% in Nigeria, 10% in Egypt, 6.7% in China, 9.2% in India, 9.1% in Iran and 5.1-7.8% in Russia. Few studies examined the etiology of OM and the antibacterial resistance. The most common bacterial pathogens were S. pneumoniae, H. influenzae and S. aureus. A high resistance to penicillin was reported in Nigeria and Turkey. CONCLUSIONS Despite the variability between the identified studies, this review indicates that OM and its various sub-types remain a significant burden in different settings. However, the heterogeneity of studies and a general lack of reliable data made generalisation very difficult.

Abstract
AIM We aimed to describe the detection rate spectrum of clinical manifestations, and outcome of pneumococcal disease in children younger than 5 years admitted to the largest referral pediatric hospital in Egypt. MATERIALS AND METHODS This was a hospital-based study to detect laboratory-confirmed Streptococcus pneumoniae cases among children younger than 5 years. Data on demographic characteristics, clinical diagnosis, comorbidities, diagnostic tests, antibiotic resistance, and clinical outcome were collected during the study years from 2008 to 2011. RESULTS During the 4-year study period, 22 018 cases younger than 5 years had cultures performed at Cairo University Pediatric Hospital microbiology laboratory. We estimated the annual detection rate of total Streptococcus pneumonia infection to be 54.5/100 000. The incidence of invasive pneumococcal disease (IPD) was half the incidence of non-IPD (18.2 and 36.4/100 000, respectively). Infants of 1 year or younger were statistically more vulnerable to Streptococcus pneumonia infection compared with children between 1 and 5 years of age (annual rate: 110.5/100 000 and 21.6/100 000, respectively). The overall pneumococcal annual case fatality was 33.3% and was higher in IPD (75%) than in non-IPD (12.5%) cases. There was an obviously increasing trend of the pneumococcal detection rate throughout the 4 years of the study (P<0.0001). CONCLUSION AND RECOMMENDATIONS Our results confirm the substantial and increasing pneumococcal infection, the emerging of multidrug resistant isolates, and the vulnerability of the younger age group and high-risk population, which calls for a national surveillance to inform policy and decision-making before national wide vaccine introduction.

Abstract
The objective of this study was to describe the epidemiology of invasive pneumococcal disease (IPD) in Omani children. We retrospectively reviewed cases admitted in children <5 years of age who were admitted in one of 4 tertiary care facilities within the Muscat Governorate. These cases represented nearly 95% of all IPD admissions recorded throughout the country from 1 January 2006 to 31 December 2006. Cases of IPD were identified using the ICD-10 discharge code. Case definition required microbiological confirmation (i.e., isolation of Streptococcus pneumoniae from blood, cerebrospinal fluid or any other normally sterile biological fluid) or clinical diagnosis in the absence of a specimen. A total of 41 cases of IPD were identified. The annual incidence of IPD was 26.1 per 100,000 in children <2 years old and 18.6 per 100,000 in children <5 years old. Among the reported IPD cases, 22 (54%) isolates were resistant to at least one antibiotic and 15 (37%) of patients had a known comorbid medical condition. These results demonstrate that the incidence of IPD in Oman during 2006 was high compared to many of the neighboring countries and provides baseline data on the incidence of IPD in an era before the introduction of the pneumococcal conjugate vaccine (PCV). In light of evidence for a significant incidence of IPD, we recommended that a nationwide surveillance system be put in place to monitor the incidence of IPD in children <5 years of age in Oman and to document the impact of PCV.

Abstract
Despite efforts in prevention worldwide including recent advances in vaccine therapy, childhood community acquired pneumonia (CAP) remains a major cause of morbidity and mortality both in the developed and the developing world. Traditionally, qualifying the aetiology of CAP proved to be fraught with challenges particularly due to low yields from blood and sputum specimens. In recent years however, new advances in techniques such as enzyme-linked immunosorbent assay and polymerase chain reaction have dramatically improved detection rates of both bacteria and viruses. In addition to qualifying the true burden of disease by known organisms such as Streptococcus pneumoniae it has led to the identification of organisms such as human bocavirus which have not previously been associated with CAP. This article aims to provide a brief update to the clinician on the current epidemiology of CAP in this post-vaccination era. It is based on a combination of recommendations from existing clinical practice guidelines, recent systematic reviews and the current literature.
