ABSTRACT
Background We studied the clinical features and treatment outcome of patients with melioidosis in our hospital. Methods We did this retrospective observational chart review over a period of 7 years between December 2014 and February 2022. Results There were 59 cases and 23 deaths attributable to melioidosis over the study period. The age range was 5 to 74 years and 48 (81.3%) were men. The comorbid conditions included diabetes mellitus (68%), alcoholism (11.8%), pulmonary tuberculosis (6.7%) and chronic kidney disease (5%). Over three-fourths of patients (78%) presented during the rainy season (June to December) and were acute presentations (44 [75%]). The most common sites were liver and spleen, followed by the musculoskeletal system, skin, soft tissues, lungs and brain. Of the 21 (36%) patients with septic shock, 16 (76%) died. On the contrary, of 38 (64%) patients without septic shock, only 11% died. Of the 27 (47%) admitted to ICU, 11 (41%) died. In ICU, 18 (67%) were ventilated. Of the 23 (39%) deaths overall, median time from admission to death was 4 days. There were no relapses in the 42% patients followed up for 2-6 months. Conclusions The epidemiology of melioidosis is similar to other endemic areas with preponderance of men. There was a temporal association with the monsoon season and a higher number of acute cases. The differences included a higher proportion of deep visceral abscesses and musculo-skeletal involvement compared to lung involvement.

BACKGROUND: Little is known about differences in patient characteristics before and after implementation of the new definition of sepsis (Sepsis-3) and whether the new definition is affecting clinical practice in intensive care units. OBJECTIVE: To examine and compare the clinicoepidemiologic characteristics of patients with sepsis or septic shock before and after implementation of Sepsis-3. METHODS: In this population-based cohort study, a nationwide registration database in South Korea was used to identify patients with sepsis or septic shock. Patients admitted to hospitals from 2012 to 2015 constituted the Sepsis-2 group, and patients admitted from 2017 to 2020 constituted the Sepsis-3 group. RESULTS: The study involved 443 217 patients, of whom 170 660 (38.5%) were in the Sepsis-2 group and 272 557 (61.5%) were in the Sepsis-3 group. The mean (SD) age was 73.3 (14.5) years in the Sepsis-2 group and 75.5 (14.5) years in the Sepsis-3 group. The intensive care unit admission rate was higher in the Sepsis-2 group (34.6%, 59 081 of 170 660) than in the Sepsis-3 group (21.3%, 57 997 of 272 557). Multivariable Cox regression analysis showed that 1-year all-cause mortality was 21% lower in the Sepsis-3 group than in the Sepsis-2 group (hazard ratio, 0.79; 95% CI, 0.78-0.79; P < .001). CONCLUSIONS: Implementation of the Sepsis-3 definition was associated with an increased number of patients with sepsis. Other findings suggested that patients in the Sepsis-2 group had more severe illness, with increased 1-year all-cause mortality, compared with those in the Sepsis-3 group.

OBJECTIVE: To analyse the preva lence of complications related to out-of-hospital cardiac arrest patients achieving target temperature management within 360 minutes compared to those taking more than 360 minutes. METHODS: The retrospective study was conducted at a medical centre in Taiwan, and comprised data from Januar y 1, 2014, to December 31, 2020. Data was retrieved using the International Classification of Diseases version 10 codes I46.2, I46.8 and I46.9 related to adult patients of either gender presenting to the Emergenc y Medicine department with out-of-hospital cardiac arrest. Data included gender, age, medical histor y, body mass index, acute physiology and chronic health evaluation II score, blood glucose levels, electrocardiogram results, and complications occurring within the target temperature management timeframe. Data was divided into group A having patients who achieved target temperature management within 360 minutes, and group B having patients with delayed TTM of more than 360 minutes. Data was analysed using SPSS 22. RESULTS: Of the 127 patients, 76(59%) were males, 51(41%) were females,, 47(37%) were aged >75 years, and 13(10.3%) were aged <50 years. Of the total, 65(51.2%) patients were in group A, and 62(48.8%) were in group B. Pneumonia, urinary tract infection, septic shock and gastrointestinal bleeding had lower incidence rates in group A than group B (p<0.05). The odds of death were 2.879 times high er in group B patients than group A (95% confidence interval: 1.908-8.916). CONCLUSIONS: Hypothermia tre atment should be sta rted as soon as pos sible to achieve target temp erature management within 360 minutes to reduce the risk of complications and mortality.

The study aimed to evaluate the prevalence, risk factors, and clinical outcomes of pulmonary embolism in patients diagnosed with sepsis with and without shock. The National Inpatient Sample was used to identify adults with sepsis with and without shock between 2017 and 2019. The prevalence of acute pulmonary embolism and the association of acute pulmonary embolism with in-hospital mortality, hospital length of stay for survivors, and overall costs of hospitalization were evaluated. Multivariable logistic and linear regression analyses, adjusted for various parameters, were used to explore these associations. Of the estimated 5,019,369 sepsis hospitalizations, 1.2% of patients with sepsis without shock and 2.3% of patients with septic shock developed pulmonary embolism. The odds ratio for in-hospital mortality was 1.94 (95% confidence interval (CI) 1.85-2.03, p < 0.001). The coefficient for hospital length of stay was 3.24 (95% CI 3.03-3.45, p < 0.001). The coefficient for total costs was 46,513 (95% CI 43,079-49,947, p < 0.001). The prevalence of pulmonary embolism in patients diagnosed with sepsis with and without shock was 1.2 and 2.3%, respectively. Acute pulmonary embolism was associated with higher in-hospital mortality, longer hospital length of stay for survivors, and higher overall costs of hospitalization.

INTRODUCTION: Sepsis is a major cause of morbidity and mortality worldwide. In the updated, 2016 Sepsis-3 criteria, sepsis is defined as life-threatening organ dysfunction caused by a dysregulated host response to infection, where organ dysfunction can be represented by an increase in the Sequential Organ Failure Assessment (SOFA) score of 2 points or more. We sought to apply the Sepsis-3 criteria to characterise the septic cohort in the Amsterdam University Medical Centres database (Amsterdam UMCdb). METHODS: We examined adult intensive care unit (ICU) admissions in the Amsterdam UMCdb, which contains de-identified data for patients admitted to a mixed surgical-medical ICU at a tertiary academic medical centre in the Netherlands. We operationalised the Sepsis-3 criteria, defining organ dysfunction as an increase in the SOFA score of 2 points or more, while infection was defined as a new course of antibiotics or an escalation in antibiotic therapy, with at least one antibiotic given intravenously. Patients with sepsis were determined to be in septic shock if they additionally required the use of vasopressors and had a lactate level >2 mmol/L. RESULTS: We identified 18,221 ICU admissions from 16,408 patients in our cohort. There were 6,312 unique sepsis episodes, of which 30.2% met the criteria for septic shock. A total of 4,911/6,312 sepsis (77.8%) episodes occurred on ICU admission. Forty-seven percent of emergency medical admissions and 36.7% of emergency surgical admissions were for sepsis. Overall, there was a 12.5% ICU mortality rate; patients with septic shock had a higher ICU mortality rate (38.4%) than those without shock (11.4%). CONCLUSIONS: We successfully operationalised the Sepsis-3 criteria to the Amsterdam UMCdb, allowing the characterization and comparison of sepsis epidemiology across different centres.

OBJECTIVES: We examined long-term outcomes of toxic shock syndrome. METHODS: We conducted a matched cohort study of 630 patients with toxic shock syndrome and 5009 healthy controls between 2006 and 2021 in Quebec, Canada. Outcomes included hospitalization for renal, cardiovascular, hepatic, and other morbidity during 15 years of follow-up. We estimated adjusted hazard ratios (HR) and 95% confidence intervals (CI) for the risk of these outcomes over time, comparing patients with toxic shock syndrome relative to matched controls. RESULTS: Compared with healthy controls, rehospitalization rates at 15 years were higher for men with toxic shock syndrome (52.0 vs 30.0 per 100) but not for women (38.7 vs 45.6 per 100). In men, toxic shock syndrome was associated with an elevated risk of renal (HR 17.43, 95% CI 6.35-47.82), cardiovascular (HR 2.57; 95% CI 1.52-4.34), and hepatic hospitalization (HR 19.83, 95% CI 4.72-83.34). In women, toxic shock syndrome was associated with renal hospitalization (HR 4.71, 95% CI 1.94-11.45). Streptococcal toxic shock was associated with a greater risk of rehospitalization than staphylococcal toxic shock. CONCLUSIONS: Toxic shock syndrome is associated with rehospitalization up to 15 years later, especially in men. These patients may benefit from continued follow-up to prevent long-term morbidity.

Acinetobacter baumannii (Ab) is a well-known nosocomial pathogen that has emerged as a cause of community-acquired pneumonia (CAP) in tropical regions. Few global epidemiological studies of CAP-Ab have been published to date, and no data are available on this disease in France. We conducted a retrospective chart review of severe cases of CAP-Ab admitted to intensive care units in Réunion University Hospital between October 2014 and October 2022. Eight severe CAP-Ab cases were reviewed. Median patient age was 56.5 years. Sex ratio (male-to-female) was 3:1. Six cases (75.0%) occurred during the rainy season. Chronic alcohol use and smoking were found in 75.0% and 87.5% of cases, respectively. All patients presented in septic shock and with severe acute respiratory distress syndrome. Seven patients (87.5%) presented in cardiogenic shock, and renal replacement therapy was required for six patients (75.0%). Five cases (62.5%) presented with bacteremic pneumonia. The mortality rate was 62.5%. The median time from hospital admission to death was 3 days. All patients received inappropriate initial antibiotic therapy. Acinetobacter baumannii isolates were all susceptible to ceftazidime, cefepime, piperacillin-tazobactam, ciprofloxacin, gentamicin, and imipenem. Six isolates (75%) were also susceptible to ticarcillin, piperacillin, and cotrimoxazole. Severe CAP-Ab has a fulminant course and high mortality. A typical case is a middle-aged man with smoking and chronic alcohol use living in a tropical region and developing severe CAP during the rainy season. This clinical presentation should prompt administration of antibiotic therapy targeting Ab.

BACKGROUND: Patients with heart failure with reduced ejection fraction (HFrEF) are at increased risk for sepsis/septic shock. METHOD: A retrospective study was conducted using the Nationwide Readmission Database (2016-2020). Adult patients admitted with sepsis or septic shock were identified and stratified based on the presence of underlying HFrEF. Multivariable logistic regression assessed the association between HFrEF and in-hospital mortality, 90-day readmission, and other complications. RESULTS: Among 7,326,930 sepsis/septic shock admissions, 6.2 % had HFrEF. HFrEF patients had higher in-hospital mortality (17 % vs. 9.6 %, p < 0.01) and 90-day readmission rates (30.2 % vs. 22.5 %, p < 0.01) compared to those without HFrEF. These differences persisted after adjustment with increased risk of in-hospital mortality (aOR 1.40, 95 %CI 1.38-1.42) and 90-day readmission (aOR 1.15, 95 %CI 1.13-1.16). CONCLUSION: HFrEF patients admitted with sepsis/septic shock have significantly higher rates of in-hospital mortality, complications, and 90-day readmissions compared to those without HFrEF.

INTRODUCTION: Postoperative sepsis represents a rare complication following thyroidectomy. We aimed to explore the incidence, risk factors, sources, and outcomes of postoperative sepsis and septic shock among adult patients undergoing thyroidectomy. METHODS: Data from the American College of Surgeons National Surgical Quality Improvement Program were used in this retrospective cohort study. Patients aged ≥18 y who underwent elective thyroidectomy between 2005 and 2019 were included. Multivariable binary logistic regression models were computed to explore risk factors and outcomes of 30-d sepsis and septic shock. RESULTS: Among the 180,373 included patients, 0.1% developed sepsis or septic shock. Male gender, low body mass index, American Society of Anesthesiologists classes 3-5, functional dependence, smoking, diabetes mellitus, pulmonary disease, inpatient surgery, malignant indication, clean-contaminated wound classification, and operation time ≥150 min were significant risk factors for development of sepsis or septic shock. Common infectious sources of sepsis included surgical site infections (29.6%), pneumonia (18.6%), urinary tract infections (16.2%), and multiple infections (6.9%). Patients with postoperative sepsis or septic shock were significantly more likely to develop complications, including wound disruption, stroke, cardiac and renal complications, thromboembolism, prolonged length of stay, unplanned reoperation, and mortality. CONCLUSIONS: Sepsis is rare following thyroidectomy. Our study provides insight into risk factors and procedural characteristics which may contribute to the development of postoperative sepsis or septic shock in this population.

BACKGROUND: Escherichia coli is the most frequent cause of bloodstream infections (BSIs). About one-third of patients with BSIs due to E coli develop sepsis or shock. The objective of this study is to characterise the microbiological features of E coli blood isolates causing sepsis or septic shock to provide exploratory information for future diagnostic, preventive, or therapeutic interventions. METHODS: E coli blood isolates from a multicentre cross-sectional study of patients older than 14 years presenting with sepsis or septic shock (according to the Third International Consensus Definitions for Sepsis and Septic Shock criteria) from hospitals in Spain between Oct 4, 2016, and Oct 15, 2017, were studied by whole-genome sequencing. Phylogroups, sequence types (STs), serotype, FimH types, antimicrobial resistance (AMR) genes, pathogenicity islands, and virulence factors were identified. Susceptibility testing was performed by broth microdilution. The main outcome of this study was the characterisation of the E coli blood isolates in terms of population structure by phylogroups, groups (group 1: phylogroups B2, F, and G; group 2: A, B1, and C; group 3: D), and STs and distribution by geographical location and bloodstream infection source. Other outcomes were virulence score and prevalence of virulence-associated genes, pathogenicity islands, AMR, and AMR-associated genes. Frequencies were compared using χ² or Fisher's exact tests, and continuous variables using the Mann-Whitney test, with Bonferroni correction for multiple comparisons. FINDINGS: We analysed 224 isolates: 140 isolates (63%) were included in phylogenetic group 1, 52 (23%) in group 2, and 32 (14%) in group 3. 85 STs were identified, with four comprising 44% (n=98) of the isolates: ST131 (38 [17%]), ST73 (25 [11%]), ST69 (23 [10%]), and ST95 (12 [5%]). No significant differences in phylogroup or ST distribution were found according to geographical areas or source of bloodstream infection, except for ST95, which was more frequent in urinary tract infections than in other sources (11 [9%] of 116 vs 1 [1%] of 108, p=0·0045). Median virulence score was higher in group 1 (median 25·0 [IQR 20·5-29·0) than in group 2 (median 14·5 [9·0-20·0]; p<0·0001) and group 3 (median 21 [16·5-23·0]; p<0·0001); prevalence of several pathogenicity islands was higher in group 1. No significant differences were found between phylogenetic groups in proportions of resistance to antibiotics. ST73 had higher median virulence score (32 [IQR 29-35]) than the other predominant clones (median range 21-28). Some virulence genes and pathogenicity islands were significantly associated with each ST. ST131 isolates had higher prevalence of AMR and a higher proportion of AMR genes, notably blaCTX-M-15 and blaOXA-1. INTERPRETATION: In this exploratory study, the population structure of E coli causing sepsis or shock was similar to previous studies that included all bacteraemic isolates. Virulence genes, pathogenicity islands, and AMR genes were not randomly distributed among phylogroups or STs. These results provide a comprehensive characterisation of invasive E coli isolates causing severe response syndrome. Future studies are required to determine the contribution of these microbiological factors to severe clinical presentation and worse outcomes in patients with E coli bloodstream infection.

BACKGROUND: Pyometra is a disease characterized by the collection of pus in the uterus. The clinical characteristics and etiology of pyometra have not been sufficiently described. In this study, we investigated the clinical characteristics, epidemiology, outcomes, and risk factors of septic shock in patients with pyometra. METHODS: Patients with pyometra admitted to one of four university-affiliated hospitals between January 2010 to August 2022 were enrolled. Pyometra cases associated with peripartum infection and surgical site infection were excluded. Clinical characteristics and outcomes of pyometra were described, and pyometra patients with or without septic shock were compared. RESULTS: A total of 192 patients was included. Twenty-eight-day all-cause mortality was 5.0%, and the 1-year recurrence rate was 6.3%. Median patient age was 77.5 years. The two most common symptoms were abdominal pain (49.0%) and vaginal discharge (47.9%). Escherichia coli (40.1%), Klebsiella pneumoniae (16.7%), and Streptococcus spp.(16.0%) were the pathogens most frequently isolated by conventional culture; those isolated from polymerase chain reaction were Mycoplasma hominis (48.0%), and Ureaplasma spp. (32.0%). In multivariable analysis, fever, uterine perforation, and dementia were associated with increased incidence of septic shock, while vaginal discharge was associated with a lower incidence of septic shock. CONCLUSIONS: Our findings suggest that pyometra is a unique gynecological infectious syndrome in post-menopausal individuals. The most common associated pathogens are similar to those involved in urinary tract infections rather than those of sexually transmitted diseases. Decreased cognitive function could delay early diagnosis of pyometra and lead to septic shock and higher mortality.

INTRODUCTION: Patients with severe neutropenia who develop septic shock (SS) have high mortality. This study aimed to evaluate the risk factors and mortality of SS in patients with HM and febrile neutropenia. METHODOLOGY: We included all patients with hematological malignancies (HM) who presented fever and severe neutropenia, admitted to an oncological tertiary care center in Mexico City for one year. RESULTS: Two hundred ninety-two episodes of fever and severe neutropenia were documented; 68 patients (23.2%) developed SS. Documented clinical infection was different between SS and non-SS patients (94.1% vs. 63.4%, p < 0.001); pneumonia was the most frequent infection (36.8% vs. 23.2%, p = 0.02). Also, in SS vs. non-SS, there were more positive cultures (69.1% vs. 38.4%, p < 0.001), higher frequency of Gram-negative bacteria (89.3% vs. 63.9%, p < 0.001), particularly Escherichia coli (68% vs. 44.2%) and Klebsiella spp. (23.4% vs. 15.1%). There were no differences when multidrug-resistant (MDR) microorganisms were compared. In the multivariate analysis, associated risk factors for SS were: prolonged neutropenia, a documented site of infection, and having received highly myelosuppressive chemotherapy. Risk factors for mortality at 30 days were: older patients, prolonged neutropenia, and SS. CONCLUSIONS: Severe and prolonged neutropenia was associated with SS development and mortality at 30 days. ICU management should be offered to all critically ill patients with HM if long-term survival of the underlying malignancy is expected.

OBJECTIVE: Prior studies have demonstrated the adverse effects of upper respiratory infections on the pediatric population, such as increased risk for acute otitis media (AOM). Other studies have noted decreased otitis media complaints during the COVID-19 pandemic. This project aims to identify whether individuals who tested positive for COVID-19 at the Emergency Department (ED) visit had an increased risk of developing severe complications. Additionally, we will study whether vaccination helped decrease following COVID-19 complications. METHODS: Utilizing the TriNetX database, we obtained de-identified electronic medical records for children under five and 6-10 years old from 2020-2023 in the United States. The study population was propensity-matched for gender, index age, and comorbidities. Complications within eight weeks of the ED visit were compared between COVID-19 vaccinated and unvaccinated children. Risk ratio was used to measure associations between our groups. A p-value less than or equal to 0.05 was considered significant. RESULTS: After propensity matching, a total of 211,138 children were identified. Within eight weeks after the ED visit, unvaccinated children <5 years old who tested negative for COVID-19 had a 30 % relative risk reduction for AOM, 52 % for sinusitis, 76 % for multisystem inflammatory system (MIS), 17 % for acute respiratory failure, and 37 % for septic shock when compared to those with a positive COVID-19 result (p ≤ 0.05). Unvaccinated 6-10 years old children who tested negative for COVID-19 had an 18 % risk reduction for AOM, 44 % reduction for sinusitis, 63 % reduction for MIS, and 42 % for acute respiratory failure (p ≤ 0.05) compared to those that tested positive for COVID-19. Vaccinated children with positive COVID-19 results have no significant risk of AOM or acute respiratory failure. Additionally, children 6-10 years old with positive COVID-19 results did not have a substantial risk of sinusitis. CONCLUSION: COVID-19's effects require continued investigation in children. This study showed that there are some increased risks of severe complications following this viral infection.

INTRODUCTION: Acute necrotizing pancreatitis (ANP) mortality increases when pancreatic necrosis is infected (IPN). Current treatment of IPN relies on prolonged antibiotic therapies associated with a step-up strategy of drainage. The objective of this study was to analyze IPN treatment outcomes in two referral centers in France. METHODS: Data of consecutive patients with documented IPN hospitalized in two expert centers in France between 2014 and 2019 were retrospectively reviewed. The composite primary outcome was the proportion of unsuccessful management outcome, defined as new emergency drainage to treat sepsis with organ failure, an unplanned new antibiotic course, an unplanned prolongation of antibiotic course and/or death by septic shock, within three months following the diagnosis of ANP. RESULTS: All in all, 187 patients (138 males; 74.0%), with documented IPN were included. The most frequently identified microorganism was Escherichia coli (26.2%). Ninety-eight patients (52.4%) were admitted to an intensive care unit or resuscitation ward within the first two days of ANP care. Overall, 126 patients (67.4%) endured an unsuccessful outcome: new emergency drainage to treat acute sepsis (62.0%), unplanned new antibiotic course (47.1%), unplanned prolongation of antibiotic course (44.9%) and/or death by septic shock complicating IPN (8.0%). CONCLUSION: The unfavorable evolution in two thirds of patients shows that determination of optimal drainage timing and choice of antibiotic therapy remain major challenges in 2024.

OBJECTIVES: Streptococcal toxic shock syndrome (STSS) is caused by group A Streptococcus (GAS; Streptococcus pyogenes) strains. In Japan, the number of STSS cases has decreased; however, the underlying reason remains unclear. Moreover, information on distribution and prevalence of specific emm types in STSS cases is scarce. Hence, we investigated the reason for the decreased number of STSS cases in Japan. METHODS: We genotyped emm of 526 GAS isolates obtained from 526 patients with STSS between 2019 and 2022. The distributions of emm types in each year were compared. RESULTS: The emm1 type was predominant, with the highest proportion in 2019, which decreased after 2020 following the onset of the coronavirus disease 2019 (COVID-19) pandemic. Strains isolated during the pandemic correlated with strains associated with skin infection, whereas those isolated during the prepandemic period correlated with strains associated with both throat and skin infections. The decrease in the annual number of STSS cases during the COVID-19 pandemic could be due to a decreased proportion of strains associated with pharyngeal infections. CONCLUSIONS: Potential associations between pandemic and STSS numbers with respect to public health measures, such as wearing masks and changes in healthcare-seeking behavior, may have affected the number of GAS-induced infections.

OBJECTIVES: To describe the epidemiological characteristics of pediatric sepsis in Southwest China PICUs. DESIGN: A prospective, multicenter, and observational study. SETTING: Twelve PICUs in Southwest China. PATIENTS: The patients admitted to the PICU from April 1, 2022, to March 31, 2023. The age ranged from 28 days to 18 years. All patients met the criteria of severe sepsis or septic shock. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of the 31 PICUs invited to participate, 12 PICUs (capacity of 292 beds) enrolled patients in the study. During the study period, 11,238 children were admitted to the participating PICUs, 367 (3.3%) of whom met the diagnosis of severe sepsis or septic shock. The most prevalent sites of infection were the respiratory system (55%) and the digestive system (15%). The primary treatments administered to these patients included antibiotics (100%), albumin (61.3%), invasive mechanical ventilation (58.7%), glucocorticoids (55.6%), blood products (51%), gammaglobulin (51%), and vasoactive medications (46.6%). Sepsis-related mortality in the PICU was 11.2% (41/367). Nearly half of the sepsis deaths occurred within the first 3 days of PICU admission (22/41, 53.7%). The mortality rate of septic shock (32/167, 19.2%) was significantly higher than that of severe sepsis (9/200, 4.5%; p < 0.001). The outcomes of a multivariate logistic regression analysis suggested that a higher pediatric Sequential Organ Failure Assessment score, and the use of invasive mechanical ventilation and vasoactive medications were independently associated with PICU mortality in children with sepsis. CONCLUSIONS: This report updates the epidemiological data of pediatric sepsis in PICUs in Southwest China. Sepsis is still a life-threatening disease in children.

BACKGROUND: Group A Streptococcus is responsible for severe and potentially lethal invasive conditions requiring intensive care unit (ICU) admission, such as streptococcal toxic shock-like syndrome (STSS). A rebound of invasive group A streptococcal (iGAS) infection after COVID-19-associated barrier measures has been observed in children. Several intensivists of French adult ICUs have reported similar bedside impressions without objective data. We aimed to compare the incidence of iGAS infection before and after the COVID-19 pandemic, describe iGAS patients' characteristics, and determine ICU mortality associated factors. METHODS: We performed a retrospective multicenter cohort study in 37 French ICUs, including all patients admitted for iGAS infections for two periods: two years before period (October 2018 to March 2019 and October 2019 to March 2020) and a one-year after period (October 2022 to March 2023) COVID-19 pandemic. iGAS infection was defined by Group A Streptococcus isolation from a normally sterile site. iGAS infections were identified using the International Classification of Diseases and confirmed with each center's microbiology laboratory databases. The incidence of iGAS infections was expressed in case rate. RESULTS: Two hundred and twenty-two patients were admitted to ICU for iGAS infections: 73 before and 149 after COVID-19 pandemic. Their case rate during the period before and after COVID-19 pandemic was 205 and 949/100,000 ICU admissions, respectively (p < 0.001), with more frequent STSS after the COVID-19 pandemic (61% vs. 45%, p = 0.015). iGAS patients (n = 222) had a median SOFA score of 8 (5-13), invasive mechanical ventilation and norepinephrine in 61% and 74% of patients. ICU mortality in iGAS patients was 19% (14% before and 22% after COVID-19 pandemic; p = 0.135). In multivariate analysis, invasive mechanical ventilation (OR = 6.08 (1.71-21.60), p = 0.005), STSS (OR = 5.75 (1.71-19.22), p = 0.005), acute kidney injury (OR = 4.85 (1.05-22.42), p = 0.043), immunosuppression (OR = 4.02 (1.03-15.59), p = 0.044), and diabetes (OR = 3.92 (1.42-10.79), p = 0.008) were significantly associated with ICU mortality. CONCLUSION: The incidence of iGAS infections requiring ICU admission increased by 4 to 5 after the COVID-19 pandemic. After the COVID-19 pandemic, the rate of STSS was higher, with no significant increase in ICU mortality rate.

Objective Molecular-targeted agents, including eculizumab and rituximab, are considered treatment options for refractory myasthenia gravis (MG), but bacterial infections can occur as serious adverse events when using these agents. The present study elucidated the relative risks of bacterial infections associated with eculizumab and rituximab using a pharmacovigilance database. Methods We analyzed eculizumab- and rituximab-associated adverse events reported between 2007 and 2021 in the US Food and Drug Administration Adverse Event Reporting System (FAERS) and herein report a refractory MG patient who developed streptococcal toxic shock syndrome during eculizumab treatment. Patients We evaluated a 74-year-old Japanese woman with refractory MG who developed severe bacteremia after receiving eculizumab. Results A total of 44,215 and 108,485 adverse events were reported with eculizumab and rituximab, respectively, from among 13,742,321 individual case safety reports in the FAERS database after data cleaning. We found a strong association between eculizumab and Neisseria infections. In contrast, we found only one case of meningococcal meningitis treated with rituximab. Both eculizumab and rituximab were weakly associated with streptococcal infections. Two cases of streptococcal toxic shock syndrome were associated with rituximab. Conclusion Careful monitoring of serious bacterial infections associated with eculizumab treatment is warranted.

This research is an attempt to investigate the benefit of sodium-glucose cotransporter-2 inhibitor (SGLT2I) use in patients with diabetes mellitus (DM) for outcomes of sepsis/septic shock. We used Taiwan's national data set to identify patients and patients' characteristics to investigate sepsis/septic shock among diabetes patients who use SGLT2I compared to those who do not. We have compared the two groups for several relevant categories of potential risk factors for sepsis/septic shock and adjusted the Cox regression models accordingly. The adapted diabetes complications severity index (DCSI) was used for stratifying the advancing disease of DM. Compared to patients with DCSI = 0, patients with DCSI ≥ 2 had a significantly higher risk of sepsis/septic shock (adjusted HR = 1.52, 95% CI = 1.37-1.68). A significantly lower risk of sepsis/septic shock events was observed in the SGLT2I cohort than in the non-SGLT2I cohort with the DCSI groups [adjusted HR = 0.6 (DCSI group = 0), adjusted HR = 0.61 (DCSI group = 1), adjusted HR = 0.55 (DCSI group ≥ 2)]. Patients who received SGLT2I for a cumulative duration of ≥ 90 days had a significantly lower risk of sepsis/septic shock than patients with a duration of < 90 days (adjusted HR = 0.36, 95% CI = 0.34-0.39). We described a decreased risk of sepsis/septic shock among diabetic patients who took SGLT2I.

BACKGROUND: Pediatric acute myeloid leukemia (AML) chemotherapy increases the risk of life-threatening complications, including septic shock (SS). An area-based measure of social determinants of health, the social disorganization index (SDI), was hypothesized to be associated with SS and SS-associated death (SS-death). METHODS: Children treated for de novo AML on two Children's Oncology Group trials at institutions contributing to the Pediatric Health Information System (PHIS) database were included. The SDI was calculated via residential zip code data from the US Census Bureau. SS was identified via PHIS resource utilization codes. SS-death was defined as death within 2 weeks of an antecedent SS event. Patients were followed from 7 days after the start of chemotherapy until the first of end of front-line therapy, death, relapse, or removal from study. Multivariable-adjusted Cox regressions estimated hazard ratios (HRs) comparing time to first SS by SDI group. RESULTS: The assembled cohort included 700 patients, with 207 (29.6%) sustaining at least one SS event. There were 233 (33%) in the SDI-5 group (highest disorganization). Adjusted time to incident SS did not statistically significantly differ by SDI (reference, SDI-1; SDI-2: HR, 0.84 [95% confidence interval (CI), 0.51-1.41]; SDI-3: HR, 0.70 [95% CI, 0.42-1.16]; SDI-4: HR, 0.97 [95% CI, 0.61-1.53]; SDI-5: HR, 0.72 [95% CI, 0.45-1.14]). Nine patients (4.4%) with SS experienced SS-death; seven of these patients (78%) were in SDI-4 or SDI-5. CONCLUSIONS: In a large, nationally representative cohort of trial-enrolled pediatric patients with AML, there was no significant association between the SDI and time to SS.
