Increasing Rate of Fatal Streptococcus pyogenes Bacteriemia-A Challenge for Prompt Diagnosis and Appropriate Therapy in Real Praxis. Microorganisms 2024; 12:995. [PMID: 38792824 PMCID: PMC11124258 DOI: 10.3390/microorganisms12050995] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2024] [Revised: 05/11/2024] [Accepted: 05/13/2024] [Indexed: 05/26/2024] Open
Abstract
Streptococcus pyogenes, group A streptococci (GAS) bacteriaemia, is a life-threatening infection with high mortality, requiring fast diagnosis together with the use of appropriate antibiotic therapy as soon as possible. Our study analysed data from 93 patients with GAS bacteraemia at the General University Hospital in Prague between January 2006 and March 2024. In the years 2016-2019 there was an increase in GAS bacteraemia. Mortality in the period 2006-2019 was 21.9%; in the period 2020-2024, the mortality increased to 41.4%, p = 0.08. At the same time, in the post-2020 period, the time from hospital admission to death was reduced from 9.5 days to 3 days. A significant predictor of worse outcome in this period was high levels of procalcitonin, >35.1 µg/L (100% sensitivity and 82.35% specificity), and lactate, >5 mmol/L (90.91% sensitivity and 91.67% specificity). Myoglobin was a significant predictor in both compared periods, the AUC was 0.771, p = 0.044, and the AUC was an even 0.889, p ≤ 0.001, respectively. All isolates of S. pyogenes were susceptible to penicillin, and resistance to clindamycin was 20.3% from 2006-2019 and 10.3% in 2020-2024. Appropriate therapy was initiated in 89.1%. and 96.6%, respectively. We hypothesise that the increase in mortality after 2020 might be due to a decrease in the immune status of the population.

Invasive group A streptococcal infections in children and adolescents in Denmark during 2022-23 compared with 2016-17 to 2021-22: a nationwide, multicentre, population-based cohort study. THE LANCET. CHILD & ADOLESCENT HEALTH 2024; 8:112-121. [PMID: 38103567 DOI: 10.1016/s2352-4642(23)00295-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Revised: 10/27/2023] [Accepted: 11/02/2023] [Indexed: 12/19/2023]
Abstract
BACKGROUND A historic increase in paediatric invasive group A streptococcal (iGAS) infections was reported globally in 2022. iGAS infections can lead to severe manifestations (eg, pleural empyema, necrotising fasciitis, toxic shock syndrome, osteomyelitis, septic arthritis, and meningitis). We aimed to compare the incidence and severity of iGAS infections overall, for distinct clinical phenotypes, and for GAS emm variants in Denmark in 2022-23 with reference to the previous six seasons (ie, 2016-17, 2017-18, 2018-19, 2019-20, 2020-21, and 2021-22). METHODS In this nationwide, multicentre, population-based cohort study, we included all children and adolescents in Denmark aged 0-17 years with a positive culture of GAS or GAS confirmed through PCR-based methods from otherwise sterile sites in 2022-23 and the previous six seasons from 2016-17 to 2021-22. For all seven seasons, data were obtained from week 21 to week 20 of the next year. Patients at all 18 paediatric hospital departments in Denmark were identified through the Danish Microbiology Database, in which iGAS isolates from sterile sites are prospectively registered, including emm typing. We obtained electronic medical health records for each patient admitted with a diagnosis of iGAS. We calculated the incidence of iGAS per 1 000 000 inhabitants aged 0-17 years in each season from week 21 to week 20 of the next year and the risk ratios (RRs) for incidence of iGAS, distinct disease manifestations, and emm variants in 2022-23 versus the three pre-COVID-19 seasons in 2016-17, 2017-18, and 2018-19 using Fisher's exact test and Pearson's χ2 test. FINDINGS Among the Danish population of 1 152 000 children and adolescents aged 0-17 years, 174 with iGAS disease were included. 76 children and adolescents with iGAS during 2022-23 were identified; 31 (41%) of 76 were female and 45 (59%) were male. 98 children and adolescents with iGAS during 2016-17 to 2021-22 were identified; 41 (42%) of 98 were female and 57 (58%) were male. There was an increase in incidence of iGAS from mean 22·6 (95% CI 14·7-33·1) per 1 000 000 children and adolescents during 2016-17 to 2018-19 to 66·0 (52·0-82·6) per 1 000 000 during 2023-23 (RR 2·9, 95% CI 1·9-4·6; p<0·0001). During the COVID-19 pandemic in 2019-20, 2020-21, and 2021-22, the mean incidence of iGAS was 6·1 (95% CI 2·4-12·5) per 1 000 000 children and adolescents. In 2022-23, there was a 9·5-fold increase in emm-12 (95% CI 2·2-40·8; p=0·0002) and a 2·7-fold increase in emm-1 (1·3-5·5; p=0·0037). The most common clinical manifestations of iGAS in 2022-23 were soft-tissue infections, which increased by 4·5-fold (1·9-10·9; p=0·0003), and complicated pneumonia with parapneumonic effusion, which increased by 4·0-fold (1·4-11·4; p=0·0059), both compared with the three pre-COVID-19 seasons. Overall, there was no increased severity of iGAS in 2022-23 compared with the previous six seasons as measured by median duration of hospital stay (8 days, IQR 4-14 vs 9 days, 5-15; p=0·39), paediatric intensive care unit (PICU) admission (17 [22%] of 76 vs 17 [17%] of 98; p=0·53), duration of stay in PICU (4 days, IQR 2-10 vs 4 days, 2-11; p=0·84), or mortality (three [4%] of 76 vs three [3%] of 98; p=1·00). In 2022-23, there was a 3·6-fold (95% CI 1·8-7·3; p=0·0001) increase in children with a preceding upper respiratory tract infection and a 4·6-fold (1·5-14·1; p=0·0034) increase in children with a preceding varicella-zoster infection, both compared with the three pre-COVID-19 seasons. INTERPRETATION In Denmark, the incidence of paediatric iGAS increased in 2022-23 compared with the three pre-COVID-19 seasons of 2016-17, 2017-18, and 2018-19. However, the course of iGAS disease in children and adolescents in 2022-23 was not more severe than in previous seasons. The high morbidity across all seasons highlights iGAS as a major invasive bacterial infection in children and adolescents. FUNDING Innovation Fund Denmark.

Abstract
Foodborne Diseases (FBDs) are a worldwide problem and occur after contaminated food has been ingested, signaling a lack of food quality. Even though the SARS-CoV-2 virus is not transmitted through food, the COVID-19 pandemic has caused several challenges worldwide that have had direct implications on food production and handling, stimulating and reinforcing the adoption of good manufacturing and food handling practices. The aim of this study was to analyze data on notifications of FBD in Brazil in the years before (2018 and 2019) and during (2020 and 2021) the COVID-19 pandemic. Secondary data from the National System of Notifiable Diseases was analyzed, evaluating: overall incidence rate, lethality and mortality, contamination sites, and criteria for confirming the etiological agent. There were 2206 records of FBDs, and the mortality rate was 0.5% in both periods. The incidence rate before the pandemic was 6.48 and during the pandemic was 3.92, while the mortality coefficient was 0.033 before and 0.019 during the pandemic, both per 100,000 inhabitants. There was no significant difference in the number of FBD notifications in the evaluated periods. There was a migration of the location of FBD, with a significant increase in FBD notifications in hospitals and health units and a reduction in notifications from social events. There was a significant increase in the type of criteria used to confirm outbreaks, with an increase in clinical laboratory tests and clinical reports for bromatology. The increase in notifications in hospitals and health units demonstrates the necessity of improving food safety knowledge and the attitudes and practices of food handlers and healthcare professionals.

Abstract
OBJECTIVE To describe the space-time evolution of TB incidence rates (TI) in indigenous and non-indigenous people, according to the Federative Units (UF) of Brazil, from 2011 to 2022. METHODS Ecological, temporal, and spatial study on new tuberculosis cases in Brazil among indigenous and non-indigenous populations. Data from the Notifiable Diseases Information System (Sinan) were collected from 2011 to 2022 and stratified by Federal Unit, explored and statistically analyzed using R software version 4.2.3. RESULTS The mean TI among indigenous populations in Brazil was 71.7 new cases per 100,000 inhabitants, while for non-indigenous populations it was 28.6/100,000 inhabitants. The regions of the country that presented the highest (mean) incidence among indigenous populations were: Central-West (102.8/100,000 inhabitants), Southeast (99.6/100,000 inhabitants), and North (79.9/100,000 inhabitants). For non-indigenous populations the highest incidence was in the North region (36.5/100,000 inhabitants), followed by the Southeast (31.3/100,000), and the Northeast (27,4/100,000 inhabitants). The analysis showed that the highest incidence of TB cases among indigenous populations occurred in the states of: SP, RO, RJ, MS, MT e PA. CONCLUSION High incidence of the disease compared to the non-indigenous population show the need for a specific approach to address the health needs of these populations. Regional disparities in incidence indicate the need to address socioeconomic and infrastructure issues that affect the health of indigenous populations.

Characteristics and related factors of waterborne and foodborne infectious disease outbreaks before and after the onset of the COVID-19 pandemic (2017-2021) in the Republic of Korea: a descriptive study. Osong Public Health Res Perspect 2023; 14:483-493. [PMID: 38204427 PMCID: PMC10788414 DOI: 10.24171/j.phrp.2023.0221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Revised: 10/17/2023] [Accepted: 11/12/2023] [Indexed: 01/12/2024] Open
Abstract
BACKGROUND The incidence of waterborne and foodborne infectious diseases (WFIDs) continues to increase annually, attracting significant global attention. This study examined trends in WFID outbreaks in the Republic of Korea over the 5-year period before and during the coronavirus disease 2019 (COVID-19) pandemic and provided foundational data to establish measures for the prevention and control of WFID outbreaks. METHODS We analyzed 2,541 WFID outbreaks from 2017 to 2021 (42,805 cases) that were reported through the Integrated Disease Surveillance System of the Korea Disease Control and Prevention Agency. Outbreaks were defined as the occurrence of gastrointestinal symptoms in ≥2 individuals within a group with temporal and regional epidemiological associations. The related factors associated with WFID outbreaks during the observation period were statistically analyzed. RESULTS The total number of WFID outbreaks significantly decreased in 2020 during the COVID-19 pandemic and increased to the pre-pandemic level in 2021. Different patterns were observed for each pathogen. The incidence of Salmonella outbreaks more than doubled, while norovirus outbreaks decreased significantly. CONCLUSION WFID outbreaks in the Republic of Korea showed different patterns before and during the COVID-19 pandemic, influenced by infection control measures and changes in dietary consumption patterns. Outbreaks of some diseases increased, but the infection control measures applied during the pandemic resulted in a significant decrease in the overall number of WFID outbreaks. This highlights the importance of strengthening the management strategies for outbreak prevention through hygiene inspections, long-term monitoring, education, and promotion by conducting multidimensional analyses to understand the complex related factors.

The Epidemiology of Chickenpox in England, 2016-2022: An Observational Study Using General Practitioner Consultations. Viruses 2023; 15:2163. [PMID: 38005841 PMCID: PMC10674747 DOI: 10.3390/v15112163] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Revised: 10/24/2023] [Accepted: 10/25/2023] [Indexed: 11/26/2023] Open
Abstract
Chickenpox is a common childhood disease caused by varicella-zoster virus (VZV). VZV vaccination is not part of the UK childhood immunisation programme, but its potential inclusion is regularly assessed. It is therefore important to understand the ongoing burden of VZV in the community to inform vaccine policy decisions. General practitioner (GP) chickenpox consultations were studied from 1 September 2016 to 9 December 2022. Over the study period, the mean weekly chickenpox consultation rate per 100,000 population in England was 3.4, with a regular peak occurring between weeks 13 and 15. Overall, rates decreased over time, from a mean weekly rate of 5.5 in 2017 to 4.2 in 2019. The highest mean weekly rates were among children aged 1-4 years. There was no typical epidemic peak during the COVID-19 pandemic, but in 2022, rates were proportionally higher among children aged < 1 year old compared to pre-pandemic years. Chickenpox GP consultation rates decreased in England, continuing a longer-term decline in the community. The COVID-19 pandemic impacted rates, likely caused by the introduction of non-pharmaceutical interventions to prevent SARS-CoV-2 transmission. The lasting impact of the interruption of typical disease transmission remains to be seen, but it is important to monitor the chickenpox burden to inform decisions on vaccine programmes.
