Surviving Sepsis Campaign International Guidelines for the Management of Septic Shock and Sepsis-Associated Organ Dysfunction in Children

Evaluation of Disseminated Intravascular Coagulation in Critically Ill Pediatric Hemato-oncology Patients with Septic Shock

BACKGROUND

 Disseminated intravascular coagulation (DIC) is a serious complication in septic shock. This study aimed to evaluate DIC and associated clinical outcomes using the International Society on Thrombosis and Hemostasis (ISTH) and modified ISTH overt DIC scores in critically ill pediatric hemato-oncology patients with septic shock.

METHODS

 Pediatric hemato-oncology patients with septic shock admitted to the pediatric intensive care unit (PICU) of a tertiary children's hospital between January 2013 and February 2020 were included. We modified the ISTH overt DIC score by eliminating the platelet domain and compared the performances of the ISTH and the modified ISTH overt DIC scores in DIC diagnosis and PICU mortality prediction of these patients.

RESULTS

 DIC was diagnosed in 56.4 and 38.5% of patients by ISTH and modified ISTH overt DIC scores, respectively. Patients with DIC showed a higher pediatric risk of mortality (PRISM) III, pediatric sequential organ failure assessment (pSOFA) scores, and PICU mortality than those without DIC (p < 0.05). The modified ISTH overt DIC score was an independent prognostic factor for PICU mortality and showed a larger area under the receiver operating characteristic curve than the ISTH overt DIC score (0.687 vs. 0.695). Addition of the DIC diagnosis improved the performance of PRISM III in predicting PICU mortality.

CONCLUSION

 Critically ill pediatric hemato-oncology patients with septic shock frequently experience DIC, which was adequately evaluated by both ISTH and modified ISTH overt DIC scores. Considering the characteristics of these patients, the modified ISTH overt DIC score may be a promising prognostic factor for clinical outcomes in these critically ill pediatric patients.

Clinical Characteristics and Outcomes of Hospitalized and Critically Ill Children and Adolescents with Coronavirus Disease 2019 at a Tertiary Care Medical Center in New York City

OBJECTIVE

To describe the clinical profiles and risk factors for critical illness in hospitalized children and adolescents with coronavirus disease 2019 (COVID-19).

STUDY DESIGN

Children 1 month to 21 years of age with COVID-19 from a single tertiary care children's hospital between March 15 and April 13, 2020 were included. Demographic and clinical data were collected.

RESULTS

In total, 67 children tested positive for COVID-19; 21 (31.3%) were managed as outpatients. Of 46 admitted patients, 33 (72%) were admitted to the general pediatric medical unit and 13 (28%) to the pediatric intensive care unit (PICU). Obesity and asthma were highly prevalent but not significantly associated with PICU admission (P = .99). Admission to the PICU was significantly associated with higher C-reactive protein, procalcitonin, and pro-B type natriuretic peptide levels and platelet counts (P < .05 for all). Patients in the PICU were more likely to require high-flow nasal cannula (P = .0001) and were more likely to have received Remdesivir through compassionate release (P < .05). Severe sepsis and septic shock syndromes were observed in 7 (53.8%) patients in the PICU. Acute respiratory distress syndrome was observed in 10 (77%) PICU patients, 6 of whom (46.2%) required invasive mechanical ventilation for a median of 9 days. Of the 13 patients in the PICU, 8 (61.5%) were discharged home, and 4 (30.7%) patients remain hospitalized on ventilatory support at day 14. One patient died after withdrawal of life-sustaining therapy because of metastatic cancer.

CONCLUSIONS

We describe a higher than previously recognized rate of severe disease requiring PICU admission in pediatric patients admitted to the hospital with COVID-19.

Molecular Targets in the Chemotherapy of Coronavirus Infection

In the pathogenesis of the infectious process in the respiratory tract by SARS, MERS, and COVID-19 coronaviruses, two stages can be distinguished: early (etiotropic) and late (pathogenetic) ones. In the first stage, when the virus multiplication and accumulation are prevalent under insufficient host immune response, the use of chemotherapeutic agents blocking the reproduction of the virus is reasonable to suppress the development of the disease. This article considers six major chemotherapeutic classes aimed at certain viral targets: inhibitors of viral RNA polymerase, inhibitors of viral protease Mpro, inhibitors of proteolytic activation of viral protein S allowing virus entry into the target cell, inhibitors of virus uncoating in cellular endosomes, compounds of exogenous interferons, and compounds of natural and recombinant virus-neutralizing antibodies. In the second stage, when the multiplication of the virus decreases and threatening pathological processes of excessive inflammation, acute respiratory distress syndrome, pulmonary edema, hypoxia, and secondary bacterial pneumonia and sepsis events develop, a pathogenetic therapeutic approach including extracorporeal blood oxygenation, detoxification, and anti-inflammatory and anti-bacterial therapy seems to be the most effective way for the patient’s recovery.

COVID-19 in Children: Clinical Approach and Management

COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a major public health crisis threatening humanity at this point in time. Transmission of the infection occurs by inhalation of infected droplets or direct contact with soiled surfaces and fomites. It should be suspected in all symptomatic children who have undertaken international travel in the last 14 d, all hospitalized children with severe acute respiratory illness, and asymptomatic direct and high-risk contacts of a confirmed case. Clinical symptoms are similar to any acute respiratory viral infection with less pronounced nasal symptoms. Disease seems to be milder in children, but situation appears to be changing. Infants and young children had relatively more severe illness than older children. The case fatality rate is low in children. Diagnosis can be confirmed by Reverse transcriptase - Polymerase chain reaction (RT-PCR) on respiratory specimen (commonly nasopharyngeal and oropharyngeal swab). Rapid progress is being made to develop rapid diagnostic tests, which will help ramp up the capacity to test and also reduce the time to getting test results. Management is mainly supportive care. In severe pneumonia and critically ill children, trial of hydroxychloroquine or lopinavir/ritonavir should be considered. As per current policy, children with mild disease also need to be hospitalized; if this is not feasible, these children may be managed on ambulatory basis with strict home isolation. Pneumonia, severe disease and critical illness require admission and aggressive management for acute lung injury and shock and/or multiorgan dysfunction, if present. An early intubation is preferred over non-invasive ventilation or heated, humidified, high flow nasal cannula oxygen, as these may generate aerosols increasing the risk of infection in health care personnel. To prevent post discharge dissemination of infection, home isolation for 1-2 wk may be advised. As of now, no vaccine or specific chemotherapeutic agents are approved for children.

Extremely high canine C-reactive protein concentrations > 100 mg/l - prevalence, etiology and prognostic significance

BACKGROUND

In human medicine, extremely high CRP (C-reactive protein) concentrations > 100 mg/l are indicators of bacterial infection and the need of antibiotic treatment. Similar decision limits for septic pneumonia are recommended for dogs but have not yet been evaluated for other organ systems. The aim of the retrospective study was to investigate the prevalence and evaluate dogs with CRP concentrations > 100 mg/l regarding the underlying etiology, the affected organ system and the prognostic significance.

RESULTS

Prevalence of CRP > 100 mg/l was investigated in dogs presented between 2014 and 2015 and was 12%. For evaluation of etiology and organ systems, dogs with CRP > 100 mg/l presented between 2014 and 2016 were enrolled. Dogs were classified into 4 main disease categories, i.e. inflammatory, neoplastic, tissue damage or "diverse". Diseases were assigned to the affected organ system. If an organ classification was not possible, dogs were classified as "multiple". 147 dogs with CRP 101-368 mg/l were included and classified into disease categories: 86/147 (59%) with inflammatory etiology (among these, 23/86 non-infectious, 44/86 infectious (33/44 bacterial), 19/86 inflammation non-classifiable), 31/147 (21%) tissue damage, 17/147 (12%) neoplastic (all malignant) and 13/147 (9%) diverse diseases. The affected organ systems included 57/147 (39%) multiple, 30/147 (20%) trauma, 21/147 (14%) gastrointestinal tract, 10/147 (7%) musculoskeletal system, 8/147 (5%) respiratory tract, 7/147 (5%) urinary/reproductive tract, 6/147 (4%) skin/subcutis/ear, 6/147 (4%) central/peripheral nervous system and 2/147 (1%) heart. The disease group (p = 0.081) or organ system (p = 0.17) did not have an impact on CRP. Based on CRP, a detection of bacterial infection was not possible. The prognostic significance was investigated by determining the 3-months survival and hospitalization rate in a subgroup with known outcome. The 3-months survival rate was 46/73 (63%) while the majority 66/73 (90%) of patients was hospitalized.

CONCLUSIONS

CRP concentrations > 100 mg/l are occasionally seen in a clinic population. They indicate a severe systemic disease of various etiologies with guarded prognosis. Extremely high CRP concentrations do not allow a conclusion of the underlying etiology or an identification of bacterial inflammation.

Recommendations on the clinical management of the COVID-19 infection by the «new coronavirus» SARS-CoV2. Spanish Paediatric Association working group

On 31 December 2019, the Wuhan Municipal Committee of Health and Healthcare (Hubei Province, China) reported that there were 27 cases of pneumonia of unknown origin with symptoms starting on the 8 December. There were 7 serious cases with common exposure in market with shellfish, fish, and live animals, in the city of Wuhan. On 7 January 2020, the Chinese authorities identified that the agent causing the outbreak was a new type of virus of the Coronaviridae family, temporarily called «new coronavirus», 2019-nCoV. On January 30th, 2020, the World Health Organisation (WHO) declared the outbreak an International Emergency. On 11 February 2020 the WHO assigned it the name of SARS-CoV2 and COVID-19 (SARS-CoV2 and COVID-19). The Ministry of Health summoned the Specialties Societies to prepare a clinical protocol for the management of COVID-19. The Spanish Paediatric Association appointed a Working Group of the Societies of Paediatric Infectious Diseases and Paediatric Intensive Care to prepare the present recommendations with the evidence available at the time of preparing them.

Association of Antibiotics Administration Timing With Mortality in Children With Sepsis in a Tertiary Care Hospital of a Developing Country

Objective: To investigate the association between antibiotics administration timing with morbidity and mortality in children with severe sepsis and septic shock, presenting to a tertiary care center in a developing country. Methods: This is a retrospective study of children aged 14 years or younger diagnosed with severe sepsis or septic shock at a free-standing tertiary children's hospital in Saudi Arabia between April 2015 and February 2018. We investigated the association between antibiotic administration timing and pediatric intensive care unit (PICU) mortality, PICU length of stay (LOS), hospital LOS, and ventilation-free days after adjusting for confounders. Results: Among the 189 admissions, 77 patients were admitted with septic shock and 112 with severe sepsis. Overall, the mortality rate was 16.9%. The overall median time from sepsis recognition to antibiotic administration was 105 min (IQR: 65-185.5 min); for septic shock patients, it was 85 min (IQR: 55-148 min), and for severe sepsis, 130 min (IQR: 75.5-199 min). Delayed antibiotic administration (> 3 h) was associated with 3.85 times higher PICU mortality (95% confidence intervals 1.032-14.374) in children with septic shock than in children who receive antibiotics within 3 h, after controlling for severity of illness, age, comorbidities, and volume resuscitation. However, delayed antibiotics administration was not significantly associated with higher PICU mortality in children diagnosed with severe sepsis. Conclusions: Delayed antibiotics administration in children with septic shock admitted to a free-standing children's hospital in a developing country was associated with PICU mortality.

Management of Children With Fever at Risk for Pediatric Sepsis: A Prospective Study in Pediatric Emergency Care

Objective: To study warning signs of serious infections in febrile children presenting to PED, ascertain their risk of having sepsis, and evaluate their management. Design: Prospective observational study. Setting: A single pediatric emergency department (PED). Participants: Febrile children, aged 1 month-16 years, with >= 1 warning signs of sepsis. Interventions and Main outcome measures: Clinical characteristics, including different thresholds for tachycardia and tachypnoea, and their association with (1) delivery of pediatric sepsis 6 (PS6) interventions, (2) final diagnosis of invasive bacterial infection (IBI), (3) the risk for pediatric intensive care unit (PICU) admission, and (4) death. Results: Forty-one percent of 5,156 febrile children had warning signs of sepsis. 1,606 (34%) children had tachypnoea and 1,907 (39%) children had tachycardia when using APLS threshold values. Using the NICE sepsis guidelines thresholds resulted in 1,512 (32%) children having tachypnoea (kappa 0.56) and 2,769 (57%) children having tachycardia (kappa 0.66). Of 1,628 PED visits spanning 1,551 disease episodes, six children (0.4%) had IBI, with one death (0.06%), corresponding with 256 children requiring escalation of care according to sepsis guideline recommendations for each child with IBI. There were five additional PICU admissions (0.4%). 121 (7%) had intravenous antibiotics in PED; 39 children (2%) had an intravenous fluid bolus, inotrope drugs were started in one child. 440 children (27%) were reviewed by a senior clinician. In 4/11 children with IBI or PICU admission or death, PS6 interventions were delivered within 60 min after arriving. 1,062 (65%) visits had no PS6 interventions. Diagnostic performance of vital signs or sepsis criteria for predicting serious illness yielded a large proportion of false positives. Lactataemia was not associated with giving iv fluid boluses (p = 0.19) or presence of serious bacterial infections (p = 0.128). Conclusion: Many febrile children (41%) present with warning signs for sepsis, with only few of them undergoing investigations or treatment for true sepsis. Children with positive isolates in blood or CSF culture presented in a heterogeneous manner, with varying levels of urgency and severity of illness. Delivery of sepsis care can be improved in only a minority of children with IBI or admitted to PICU.

"How to Recognize if Your Child Is Seriously Ill" During COVID-19 Lockdown: An Evaluation of Parents' Confidence and Health-Seeking Behaviors

Background: Parents' health-seeking behaviors has changed during the COVID-19 pandemic. Providing parents with guidance in decision making might improve their confidence to seek timely advice when a child becomes ill. The aim of this study was to evaluate the "How to recognize if your child is seriously ill" leaflet on parents' confidence, health-seeking behaviors, and usefulness during the COVID-19 lockdown. Method: A nine-item survey, codesigned with parent advisors, was used to measure confidence and health-seeking behavior. Social media was used for data collection in a 6-week period (April-June 2020) during COVID-19 lockdown in the United Kingdom. Categorical data were analyzed as frequencies, and inductive content analysis was performed with the qualitative data. Results: In total, 171 parents responded. Most parents (n = 160, 93.6%) found the leaflet helpful. The leaflet increased the confidence among 116 parents (67.8%) to recognize if their child is ill, and 156 (91.2%) parents had a better understanding of when and where to seek help. Thirty-three (19.2%) parents used the leaflet, while their child was unwell during COVID-19 lockdown, and in 14 (42%) cases, the leaflet resulted in changing health-seeking behavior for that episode. Twelve of these parents decided to seek medical consultation when they had not planned to before. Content analysis revealed three categories. (1) Knowledge-parents found the leaflet an objective source to validate their concerns. (2) Usability-parents reported that the leaflet was clearly designed. (3) Decision aid-parents commented that the leaflet provided clarification around recognition of serious symptoms and when and where to seek appropriate care. Conclusions: Our leaflet provided parents with guidance on decision making and risk assessment of ill children during COVID-19 lockdown. Parents found it helpful; it increased their confidence and positively changed their health-seeking behaviors. Providing parents with targeted information to recognize serious illness in children at home could potentially foster self-care and safely maintain a reduction in pediatric emergency attendances for self-limiting illnesses.
