Factors associated with adverse outcomes among SARS-CoV-2 positive children in a Tertiary Government COVID-19 Referral Hospital in the Philippines

Background and Objective@#Pediatric COVID-19 epidemiology and factors associated with adverse outcomes-mortality, need for invasive mechanical ventilation, and ICU admission, are largely unstudied. We described the clinicodemographic characteristics of Filipino pediatric COVID-19 patients and determined the factors associated with adverse outcomes.@*Methods@#This is a retrospective cohort study of 180 hospitalized SARS-CoV-2-confirmed cases 0-18 years old from April 2020 to August 2021 in a tertiary COVID-19 referral hospital in Manila, National Capital Region. Crude associations were determined using chi-squared or Fisher’s exact tests; and medians were compared using the Mann-Whitney test. Factors predictive of mortality were determined using Cox proportional hazards regression analysis. The survivor functions were depicted in graphs.@*Results@#About 41.67% had mild disease, 58.33% were males, 39.4% aged 0-4 years, and 69.44% had at least one comorbidity. About 9.44% died (adjusted 9.2 persons per 1000 patient-days, 95% CI 5.5%-15.2%), 17.78% needed invasive mechanical ventilation, and 20% needed ICU admission. Independently, severe-critical COVID-19 (HRc 11.51, 95% CI 3.23, 41.06), retractions (HRc 10.30, 95% CI 3.27, 32.47), alar flaring (HRc 4.39, 95% CI 1.53, 12.58), cyanosis (HRc 4.39, 95% CI 1.72, 14.11), difficulty of breathing (HRc 7.99, 95% CI 2.25, 28.71), poor suck/appetite (HRc 4.46, 95% CI 1.59, 12.40), ferritin (HRc 1.01, 95% CI 1.00, 1.01), IL-6 (HRc 1.01, 95% CI 1.00, 1.01), aPTT (HRc 1.05, 95% CI 1.01, 1.10), IVIg (HRc 4.00, 95% CI 1.07, 14.92) and corticosteroid (HRc 6.01, 95% CI 2.04, 17.67) were significant hazards for mortality. In adjusted Cox analysis, only retractions (HRa 34.96, 95% CI 3.36, 363.79), seizure (HRa 9.98, 95% CI 1.76, 56.55), and corticosteroids (HRa 8.21, 95% CI 1.12, 60.38) were significantly associated with mortality while alar flaring appeared to be protective (HRa 0.10, 95% CI 0.01, 0.95). Several clinical characteristics were consistently associated with adverse outcomes.@*Conclusions@#Majority of hospitalized pediatric COVID-19 patients were very young, males, had mild disease, and had at least one comorbidity. Mortality, invasive mechanical ventilation, and ICU admission were relatively low. Except for alar flaring which appeared to be protective, retractions, seizure, and use of corticosteroids were associated with adverse outcomes.

Strategic optimization of patient flow and staffing schemes during the COVID-19 pandemic through Operations Management in a Neonatal Intensive Care Unit

Background@#The COVID-19 pandemic posed challenges in making time-bound hospital management decisions. The University of the Philippines -Philippine General Hospital (UP-PGH) is a tertiary COVID-19 referral center located in Manila, Philippines. The mismatch of increasing suspected or confirmed COVID-19 infected mothers with few documented cases of infected infants has caused significant patient overflow and manpower shortage in its NICU.@*Objective@#We present an evaluated scheme for NICU bed reallocation to maximize capacity performance, staff rostering, and resource conservation, while preserving COVID-19 infection prevention and control measures.@*Methods@#Existing process workflows translated into operational models helped create a solution that modified cohorting and testing schemes. Staffing models were transitioned to meet patient flow. Outcome measurements were obtained, and feedback was monitored during the implementation phase.@*Results@#The scheme evaluation demonstrated benefits in (a) achieving shorter COVID-19 subunit length of stay; (b) better occupancy rates with minimal overflows; (c) workforce shortage mitigation with increased non-COVID workforce pool; (d) reduced personal protective equipment requirements; and (e) zero true SARS-CoV-2 infections.@*Conclusion@#Designed for hospital operations leaders and stakeholders, this operations process can aid in hospital policy formulation in modifying cohorting schemes to maintain quality NICU care and service during the COVID-19 pandemic.

Philippine pediatric COVID-19 living clinical practice guidelines as of March 2022

Executive Summary@#The Coronavirus disease 2019 (COVID-19) pandemic has triggered a global crisis and has affected millions of people worldwide. With the evolution of the different variants of concern, the incidence of COVID- 19 in the pediatric population has risen. The Surveillance and Analysis of COVID-19 in Children Nationwide (SALVACION) Registry, developed by the Pediatric Infectious Disease Society of the Philippines (PIDSP) and the Philippine Pediatric Society (PPS), has reported 3,221 cases as of March 31, 2022, with 90.4% requiring hospitalization and 36.2% with moderate to critical disease severity. Given the magnitude of the impact of COVID-19, with most of the clinical recommendations available designed towards adult patients, there was an urgent need for clinicians, public health officials and the government to also prioritize evidence-based clinical practice guidelines for the pediatric population. Hence, the development of the Philippine Pediatric COVID-19 Living Clinical Practice Guidelines was conceptualized. This independent project, funded and supported by the PPS and PIDSP, aimed to formulate up-to-date, evidence-based recommendations on the treatment, diagnosis, infection prevention and control of COVID-19 in children. Following the standard CPG development process outlined in the DOH Manual for CPG Development and the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) methodology, 15 evidence summaries and 24 recommendations were generated by 12 consensus panelists representing their specific health organizations and institutions.

Minimally invasive distal biceps tendon repair: a case series

Background@#Distal biceps tendon repairs are commonly performed using open techniques. A minimally invasive distal biceps tendon repair technique using a speculum and hooded endoscope was developed to improve visualization, reduce soft-tissue dissection, and minimize complications. This paper describes the technique and reports the outcomes of 75 minimally invasive distal biceps tendon repairs. @*Methods@#The operation reports and outcomes of 75 patients who underwent distal biceps tendon repair using this technique between 2011 and 2021 were retrospectively reviewed. @*Results@#Median time to follow-up was 12 months (interquartile range [IQR], 6–56 months). Primary outcomes were function as measured by the Disabilities of Arm, Shoulder and Hand Score (DASH) questionnaire, and rate of complications. Median DASH score was 1.7 of 100 (IQR, 0–6.8). There were 2 of 75 (2.7%) re-ruptures of the distal tendon. There were no cases of vascular injury, proximal radius fracture, or posterior interosseous nerve, median, or ulnar nerve palsy. @*Conclusions@#In this series, minimally invasive distal biceps repair was safe and effective with a low rate of major complications. Recovery of function, as indicated by low DASH scores, was satisfactory, and inconvenience during recovery was minimized.Level of evidence: IV.

Meningococcal disease and carriage in the Philippines: A review of recent data

@#This article reviews recent data on meningococcal disease and carriage in the Philippines. It aims to provide information on the epidemiology of meningococcal disease, its carriage, data on prevention, and the impact of vaccination on disease and carriage. The World Health Organization considers the Philippines as having low endemicity for meningococcal disease. However, current data underestimates the true burden in the country due to many factors. In recent years, data from the Philippines show a high case-fatality rate since only the septicemic form is being reported. Studies on asymptomatic meningococcal carriage rates are sparse, with one study by Gonzales, et al. investigating the prevalence of meningococcal nasopharyngeal carriage in Filipinos aged 5-24 years old living in an urban setting. The study showed that the overall prevalence of carriage was 3.7% and was highest (9%) among the 10-14 age group. Serogroup B was the most common isolate. Effective meningococcal vaccines are available. Although not included in the National Immunization Program, medical societies recommend giving vaccines to individuals at high risk of infection. Data on local epidemiology accounting for the disease and asymptomatic carriage are important to strengthen future programs on immunization and prevention of meningococcal disease.

The association of adherence to Antimicrobial Prophylactic Recommendations for Clean Neurosurgeries with post-operative surgical site infection

Objective@#The use of antimicrobial prophylaxis to prevent surgical site infections (SSI) is well established. This study examined the association of adherence to antimicrobial prophylaxis for clean neurosurgeries with post-operative surgical site infection (SSI) rates. @*Methods@#A retrospective descriptive study was conducted at the Philippine General Hospital (PGH) among pediatric patients who underwent clean neurosurgical procedures between January 1, 2018 – December 31, 2019. The outcome measured was the development of SSI. Univariate and multivariate analysis was performed to show the association of risk factors with SSI. Compliance to existing antibiotic prophylaxis recommendation was assessed.@*Results@#One hundred eighty-nine (189) medical charts were reviewed. Overall prevalence of SSI was 9.5% and fever was the most common initial symptom of SSI. Staphylococcus species was identified from cultures of surgical sites, consistent with existing literature, however gram-negative organisms including multidrug-resistant organisms (MDRO) were noted. All cases received prophylactic antibiotics, but adherence to all parameters (antimicrobial choice, dose, timing, route, re-dosing and duration of prophylaxis) was low at 7.9%. Appropriate antibiotics were prescribed in only 15.9% and antibiotics were discontinued beyond 24 hours post-surgery in 45.5% of cases. Patients who received a regimen fully compliant with antimicrobial prophylaxis recommendations did not develop SSI. @*Conclusion@#Adherence to existing antimicrobial prophylaxis protocol for neurosurgeries is low at 7.9%. Patients who received a regimen fully compliant with the recommendations did not develop SSI. Interventions to improve compliance to antimicrobial prophylaxis guidelines are needed.

A rapid review on the sensitivity of SARS-CoV-2 RT-PCR done on different clinical specimens

Background@#RT-PCR using respiratory tract specimens, most commonly nasopharyngeal swab (NPS), has been used to confirm the diagnosis of COVID-19. NPS is a relatively invasive procedure that causes patient discomfort and risks viral transmission. Other specimens are therefore being investigated for the detection of SARS-CoV-2 RNA. @*Objective@#To determine the sensitivity of non-respiratory tract specimens in detecting SARS-CoV-2 RNA in patients with COVID-19. @*Methodology@#This review summarized the results of eight studies obtained from a literature search done in May 2020 in PubMed MEDLINE, Cochrane Library and MedRxiv. Two independent investigators reviewed and appraised the studies that were included, and pooled estimates of sensitivity for each specimen were determined using Stata’s Metaprop function@*Results@#The sensitivity in detecting SARS-CoV-2 RNA in non-respiratory tract specimens of diagnosed COVID-19 patients are as follows: Saliva 77% (95% CI 71-83%), stool/rectal swab/anal swab 22% (95% CI 22-37%), blood/serum/plasma 2% (95% CI 1-3%), and urine 22% (95% CI 18-25%). @*Conclusion@#SARS-CoV-2 RNA is detected in saliva, stool/rectal swab/anal swab, blood/serum/plasma and urine. Among these, saliva has the highest estimated sensitivity. However, more studies are needed to correct the heterogeneity brought about by factors such as timing of specimen collection, disease severity and treatment.

Accuracy of Nasopharyngeal Aspirate GeneXpert Compared to Gastric Aspirate TB Culture and GeneXpert in Diagnosing Pulmonary Tuberculosis in Pediatric Patients

Background@#Pulmonary TB in children remains to be a burden in the Philippines. Diagnosis remains to be a challenge for pediatricians due to its paucibacillary nature, difficulty in obtaining specimens, cost of test as well as the varied sensitivity of the different tests available. Gastric aspirate (GA), commonly used for bacteriological diagnosis of pulmonary tuberculosis (PTB) in children, involves an invasive procedure that may cause discomfort and sometimes require admission. Nasopharyngeal aspirate (NPA), on the other hand, can be easily and non-invasively obtained but is currently not a recommended specimen for testing for PTB. @*Objectives@#This study aims to determine the accuracy of NPA GeneXpert in diagnosing PTB among pediatric patients 0-18 years old with presumptive TB using GA GeneXpert as the initial screening test and GA TB culture as gold standard. @*Methodology@#This prospective, cross-sectional diagnostic study involved collection of single NPA and GA specimens for GeneXpert and TB culture in 100 patients with presumptive PTB seen at a tertiary government hospital in the Philippines. @*Results@#Of the one hundred pediatric patients (mean age 6 ± 5.63 years) enrolled, 50 were clinically diagnosed PTB, 16 bacteriologically-confirmed and 34 were not PTB disease. Sensitivity, specificity and predictive values with 95% confidence intervals of the NPA GeneXpert were determined compared to GA GeneXpert and GA culture. Sensitivity, specificity, positive and negative predictive values of the NPA GeneXpert compared to GA GeneXpert were 70%, 96.67%, 70% and 96.67%, respectively. While NPA GeneXpert compared to GA TB culture were 40%,91.58%, 20% and 96.67%, respectively. @*Conclusion@#GeneXpert testing on a single NPA specimen is a highly specific and rapid test that can be used to diagnose PTB in pediatric patients, particularly where gastric aspiration or mycobacterial culture is not feasible.

Clinical characteristics and patient symptoms associated with poor outcomes among children with COVID-19: A rapid review

Objective@#To identify specific clinical characteristics and patient signs and symptoms that increase the risk of developing severe/critical COVID-19 disease or death in the pediatric population, and identify strength of these associations @*Methodology@#A systematic search was done in PubMed, Science Direct, Cochrane Library and grey literature databases focusing on severe and critical COVID-19 disease in the zero to eighteen year old age group until August 26, 2020. Data regarding patient characteristics, signs and symptoms on admission and disease severity were extracted. Outcomes measured were severe or critical COVID-19, Multisystem Inflammatory Syndrome in Children (MIS-C) or death. Results were pooled and meta-analyzed. @*Results@#Four eligible studies with a total of 292 pediatric patients with COVID-19 were examined. Older children (MD=6.62, 95%CI=4.23 to 9.00, p-value<0.00001, I2=33%) significantly present with a higher percentage of severe disease. Shortness of breath (OR=8.14, 95%CI=2.33 to 28.47, p-value=0.001, I2=42%) was also found to be associated with severe COVID-19 disease. The presence of a pre-existing medical condition (OR=4.02, 95%CI=1.55 to 10.43, p-value=0.004, I2=0%), especially cardiac disease (OR=6.40, 95%CI=1.45 to 28.38, p-value=0.01, I 2=13%) and diabetes (OR=7.01, 95%CI=1.54 to 31.95, p-value=0.01, I2=0%) was noted to be a risk factor for severe disease. @*Conclusion@#Based on poor quality observational studies, older age group, shortness of breath, and a pre-existing medical condition, especially cardiac disease or diabetes were found to be associated with poor outcomes in children with COVID-19.

Antimicrobial Stewardship (AMS) program in private hospitals in the Philippines: Its acceptability, barriers, and enablers

Background@#Antimicrobials are drugs that are often misused and inappropriate antimicrobial prescribing often results in poor clinical outcome and drug resistance. Monitoring and regulation of antimicrobial use is currently being done by the Department of Health through the Antimicrobial Stewardship (AMS) Program. There is a need to determine the factors that affect successful implementation of an AMS program in private hospitals in the Philippines. This study was conducted to identify the enablers and potential barriers in implementing an AMS program in nine (9) private hospitals. @*Methodology@#A concurrent mixed methods design was used to assess various stakeholders’ (physicians, administrators, other AMS members) perceptions of existing or proposed AMS programs, and to identify barriers and enablers in their implementation. Quantitative data were collected using self-administered survey questionnaire to assess clinician’s acceptance of AMS programs. Qualitative data were collected through semi-structured one-on-one interviews of clinicians and other AMS personnel and focus group discussions (FGD) of selected clinician groups. Data were gathered from October 2018 to October 2019. @*Results@#409 clinicians were surveyed, 52 were interviewed and 46 sat for 13 sessions of FGDs. Overall, the survey established that physicians were well aware of antimicrobial resistance problem. Majority of the clinicians indicated general agreement with the currently practiced antimicrobial protocols in their hospitals and with the AMS program. However, there were disagreements in perceptions with how antimicrobial restrictions impair prescribing practices and overuse of the same. These responses were strong points of discussion during the Key Informant Interviews (KII) and FGDs. All respondents were amenable with the institutionalization of an AMS program in their hospitals. The hospital leadership’s commitment was determined to be the key enabler of a successful AMS program’s implementation. Barriers identified for hospitals with existing AMS programs were: lack of dedicated staff, resistance and/or non-cooperation of physicians, lack of support from non-medical departments, and inadequate cooperation between hospital personnel. Barriers identified, regardless of the status of the AMS programs were: deficiency in knowledge with developing and implementing an AMS program, inadequate information dissemination, unavailability of an IT-based monitoring for antibiotic use, and the influence of pharmaceutical companies on stakeholders with regards to antimicrobial use. @*Conclusion@#Similar enablers and barriers to a successful implementation of an AMS program were seen in the different hospitals. A hospital leadership’s commitment was determined to be the key enabler. The success or failure of any AMS program appears to depend on physician understanding, commitment and support for such a program. By involving the main players in an AMS program- the hospital administrators, clinicians and other key members, perceived barriers will be better identified and overcome, and enablers will help allow a successful implementation of an AMS program. This multi-center study was funded by Philippine Council on Health Research and Development ( PCHRD) and Pediatric Infectious Disease Society of the Philippines ( PIDSP) and was conducted by the PIDSP Research Committee.

Effectiveness of daily Chlorhexidine bathing in reducing healthcare associated infections in the Pediatric Intensive Care Unit of a tertiary government hospital

Introduction@#Healthcare-associated infections (HCAIs) are a common complication of prolonged hospital stay, leading to increased morbidity and mortality. This study aims to determine the effectiveness of daily chlorhexidine bathing in reducing HCAIs in the pediatric intensive care unit (PICU).@*Methodology@#This is a randomized controlled, observer-blinded study conducted over a 6-month period. Included were 2 months to 18-year-old patients admitted to the PICU, randomly assigned to daily bathing with 2% chlorhexidine or to the standard practice of bathing with plain soap and water. Primary outcome was the incidence of HCAI in each group. @*Results@#A total of 50 patients were enrolled in the study. Overall incidence of HCAI was lower in the chlorhexidine group compared to the control group (12% versus 36%, RR=0.33, 95% CI 0.10 – 1.09, p=0.047). Incidence density rate was lower in the chlorhexidine group (5.91 versus 21.03 infections per 1000 person-days, p=0.049). Ventilator-associated pneumonia and bloodstream infections were lower in the chlorhexidine group, but results were not statistically significant. There were no significant differences in mortality rates and length of hospital stay. One adverse event of transient rash occurred in the chlorhexidine group. @*Conclusion@#Daily chlorhexidine bathing may be more effective in reducing HCAIs in the PICU compared to standard care.

Clinico-Epidemiologic profile and outcome of pediatric patients with Multi Drug Resistant Gram-Negative healthcare associated infections at the Philippine General Hospital

Introduction@#Multi Drug Resistant Organisms (MDRO) are microorganisms that are resistant to one or more classes of antimicrobial agents, and these have become significant pathogens to contend with in the treatment of Healthcare Associated Infections.@*Objectives@#This study aimed to determine the clinico-epidemiologic profile and outcome of pediatric patients with healthcare-associated multi-drug resistant gram-negative infections, and its antimicrobial susceptibility patterns. @*Methodology@#This was a retrospective study done on pediatric patients with gram negative healthcare associated MDRO sepsis compared to non-MDRO sepsis admitted at the ICU and pediatric wards of a tertiary government hospital from July 2015 to June 2016. Descriptive statistics was used to summarize the clinical characteristics of patients. Odds ratio and the corresponding 95% confidence interval from binary logistic regression was computed to determine significant predictors for the development of multi drug resistance. Outcome of patients with MDRO gram-negative infection was noted, as well as its antimicrobial susceptibility patterns. @*Results@#A total of 199 patients developed HAI, and 41% were identified to be gram negative MDR cases. Pediatric patients with healthcare associated infections due to MDR gram negative organisms had shorter hospital stay and a higher mortality rate of 78% compared to 41% among non MDR patients.The most commonly isolated gram negative organisms were Burkholderia cepacia, 38%; Klebsiella pneumoniae, 31%; and Acinetobacter baumanii, 18%; while the most common MDR gram negative isolates were Klebsiella pneumoniae, 65%; Acinetobacter aumanii, 22%; and Pseudomonas aeruginosa, 7%. Significant predictors for MDRO were age (0-28 days old), ICU admission, intravascular catheterization and use of total parenteral nutrition. @*Conclusion@#Profile of pediatric patients with healthcare-associated multidrug resistant gram-negative infections were neonates admitted in the ICU with a shorter hospital stay and a high mortality rate. The identified risk factors for developing Multi Drug Resistant Gram Negative sepsis were age of 0-28 days, admission to ICU, intravascular catheterization and parenteral nutrition. Patients with gram-negative MDR infections have a high mortality rate and isolates are susceptible mostly to Colistin.

Clinical profile, microbiology, management, and outcome of Pediatric Brain Abscess at the University of the Philippines- Philippine General Hospital: A 5-year retrospective study (2012-2016)

Objective@#To determine the clinical profile, microbiology, management, and outcome of pediatric brain abscess at a tertiary hospital in the Philippines from 2012 to 2016.@*Methods@#A retrospective study and review of medical records of 50 patients aged 18 years old and below diagnosed with brain abscess from 2012 to 2016 was performed. @*Results@#Majority of patients affected were 10 years old and below (74%), with no gender predilection, and mostly underweight/wasted (68%). Coverage for common vaccine-preventable pathogens was low (38% for H. influenzae type b, 2% for S. pneumoniae). Most common signs and symptoms on admission were fever (62%), vomiting (50%), and headache (50%). The top pre-disposing condition was congenital heart disease (46%), mostly Tetralogy of Fallot (33%). Methicillin-resistant Staphylococcus aureus (MRSA) was isolated in 38%) of cases. Sterile cultures comprised 68% of cases. There were two cases of tuberculous abscess. Empiric antibiotics administered for patients seen in 2012 were penicillin G and chloramphenicol, with a shift to a third-generation cephalosporin and metronidazole in the succeeding years. Aspiration with or without drainage was performed in majority of cases (85%). Six underwent complete excision and had a shorter mean length of stay of 57 days, and a lower morbidity rate of 17% with no mortalities. The overall mean length of hospital stay was 65 days. Residual neurologic deficit was observed in 28%, mostly extremity weakness. Mortality rate was 6.8%. No statistical association was found between a predisposing condition and affectation of a particular area of the brain using the Fisher exact test. @*Conclusion@#There should be a high index of suspicion for brain abscess among patients with pre-disposing conditions (i.e. paracranial infection, cyanotic congenital heart disease) presenting with fever, headache, and vomiting. Common etiologic agents in this study were MRSA and Enterococcus. The isolates were sensitive to the antibiotics recommended for empiric therapy, particularly parenteral third generation cephalosporin + metronidazole for 6 to 8 weeks. Patients with sterile cultures were also continued on this regimen. With the high resistance rates to oxacillin, vancomycin should be considered for abscesses arising from paracranial infections and for those with breaks in the skull post-trauma. There was an overall reduction in mortality due to improved imaging studies andidentification of pathogens for definitive treatment, as well as improved surgical techniques over time. A considerable number of affected children however had neurologic deficits upon discharge.

Intraventricular Antimicrobial Therapy in children with Multi-Drug Resistant Ventriculitis: A tertiary hospital experience and literature review

Background@#Intraventricular antimicrobial therapy (IVT), defined as the direct installation of antimicrobial agents into the lateral ventricles has been utilized as the last therapeutic option for the treatment of multidrug-resistant ventriculitis. The aim of this case series is to report our institution’s experience with IVT in pediatric patients with ventriculitis. @*Material and Methods@#Retrospective chart review was done. The demographic data, cerebrospinal fluid (CSF) culture isolates, treatment regimens, and clinical outcomes of these patients were collected and described. @*Results@#Between 2016 to 2018, seven (7) pediatric patients diagnosed with ventriculitis caused by multidrug-resistant organisms underwent intraventricular antimicrobial therapy in combination with intravenous therapy. The median age was 1 year (range 1 month to 17 years old, mean: 4.4 years). Fifty-seven (57) percent of the patients were females. The isolated pathogens were Acinetobacter baumannii MDRO (n = 3), Klebsiella pneumoniae MDRO (n = 2), Methicillin-resistant Staphylococcus aureus (n = 1), and Methicillin-resistant Staphylococcus epidermidis (n = 2).One patient had mixed isolates on CSF culture (Acinetobacter baumannii and MRSE). The antimicrobial agents for IVT used were colistin (n = 4), vancomycin (n = 2), and gentamicin (n = 1). The mean time to initiation of intraventricular therapy from the diagnosis of ventriculitis was 19 days. The mean duration of IVT therapy was 15 days. The survival rate was 57%. @*Conclusion@#Ventriculitis caused by drug-resistant organisms is an emerging concern. Optimal therapy is not yet established and experience with IVT is limited. This series showed that there were no adverse effects related to IVT thus it may be considered an option for MDRO ventriculitis. Gram negative organisms are more common causes of ventriculitis in our institution.

Procalcitonin-Guided Antibiotic Theraphy in pediatric patients: A systematic review

Background@#Serum procalcitonin is a useful biomarker in establishing the presence of bacterial infections and has been used in algorithms to guide antibiotic treatment among adults. It role in pediatric infections, however, remains unclear. @*Objectives@#This research aims to evaluate the impact of serum procalcitonin in guiding antibiotic therapy among pediatric patients with suspected local or systemic infections. @*Methodology@#Randomized controlled trials comparing procalcitonin-guided antibiotic therapy to clinically guided therapy in pediatric patients with local or systemic infections were searched through MEDLINE, Cochrane, EMBASE, HERDIN and ClinicalTrials.gov. Hand search in various search engines was also done. Outcomes included antibiotic usage, morbidity and mortality. Two reviewers independently assessed potentially relevant studies. Statistical analysis was conducted using RevMan 5.3 using inverse variance weighting and random effects model. @*Results@#Five randomized controlled trials were included. Overall, there was a reduction in antibiotic prescription rate in the procalcitonin group compared to controls for all groups (RD -0.13, 95% CI [-021,0.06]; p <0.00001), however, pooled studies were heterogenous. Subgroup analysis showed that for children with pneumonia, procalcitonin guidance significantly reduced antibiotic prescription rate (RD – 012,95% CI [-021,0.04]; p <0.005 ), and may have potential in reducing the duration of therapy (95% CI [-6.8,2,54], p <0.0001) and antibiotic-related adverse effects (RD- 0.17, 95% CI[-0.24,-0.10], p<0.00001) compared to controls. In one study on neonates with early onset sepsis, procalcitonin guidance reduced antibiotic prescription rate by 27% (p=0.0009) and duration of therapy by 22.4 hours (p=0.0009). Procalcitonin guidance has no significant impact on antibiotic prescription rate in children with fever without a source (RD -0.11, 95% CI[0.28,0.05], p=0.190). @*Conclusion@#Procalcitonin guidance significantly reduces antibiotic prescription rate among children with pneumonia and neonates with early onset sepsis. It has the potential in reducing the duration of antibiotic therapy and antibiotic-related side effects in these populations. ON the other hand, it had no impact among children with fever without a source. These results highlight the need for algorithm-based approaches using procalcitonin cut-off values to guide antibiotic therapy in children.

HBV Infection in Italian and Non-Italian Patients in Northern Italy.

Aims: The introduction of HBV vaccination in Italy has reduced the incidence and prevalence of HBV infection. However, increasing immigration from countries in which HBV is endemic has led to a wave of new HBsAg-positive subjects and their clinical impact needs evaluation. We compared the serological, clinical and epidemiological data relating to Italian and non-Italian subjects referred to a hospital in Northern Italy. Study Design: We retrospectively analysed the laboratory and clinical records of 488 subjects, including 107 (21.9%) non-Italians, in order to find data concerning clinical diagnoses, possible routes of infection, anti-HCV and anti-HDV antibodies. Results: The differences in gender distribution and mean age between the non-Italian and Italian patients were statistically significant (p<.001). There were no significant differences in the prevalence of anti-HCV (2.9% vs 4.9%, p=.86) or anti-HDV (4.7% vs 5.0%, p=.89) co-infection, or the presence of HBeAg in chronic infection. There were no differences in the rates of acute (3.3% vs 5.1%; p=.68) or chronic infections (96.7% vs 94.9%; p=.68) infections, but there were statistically significant differences (p<.001) in the rates of prevalent (54.5% vs 85.3%) and incident cases (45.5% vs 14.7%). The differences in the rates of asymptomatic (70.6% vs 34.9%) and symptomatic patients (29.4% vs 65.1%) were also statistically significant (p<.001). The only significant differences in terms of risk factors related to transfusions (0% vs 6.8%; p=.04), and vertical/perinatal transmission (44.1% vs 6.8%; p<.001). Conclusion: The non-Italian HBsAg-positive subjects were mainly women and younger than their Italian counterparts, and had a recent diagnosis. They were predominantly asymptomatic and probably considered themselves healthy and fit to emigrate. Perinatal transmission among non-Italians is still an important risk factor that reflects the epidemiological situation of their countries of origin.
