Introduction: Carbapenem-resistant Acinetobacter baumannii (CRAB) infection is being increasingly observed and is associated with significant morbidity and mortality in newborns. In this study, we determined the epidemiology, risk factors, and outcomes of blood stream infection (BSI) caused by CRAB in neonates. Methodology: The clinical charts of neonates who developed Acinetobacter baumannii BSI in the period between 1 January 2010 and 31 December 2012 were reviewed. Results: During the study period, 65 neonates developed Acinetobacter baumannii BSI; 33 were CRAB at an incidence of 0.50 case per 1,000 patient-days. Compared with carbapenem-sensitive Acinetobacter baumannii (CSAB), patients with CRAB BSI had significantly higher prior antimicrobial use, longer duration of ventilation, and late isolation of organisms. Feeding with expressed breast milk was protective. All isolates of Acinetobacter baumenii were sensitive to colistin and tigecycline. The all-cause mortality rates were 27.3% in CRAB and 9.4% in CSAB BSI, respectively (p = 0.074). Conclusions: Neonatal BSI caused by CRAB was not common but caused high mortality. Feeding with breast milk was protective. Lack of effective antibiotics was the major challenge in treating these patients.

Very little is known about healthcare-associated infections (HAIs) in neonatal intensive care units (NICUs) in resource-limited settings including, India. The aim of this prospective study was to determine the prevalence, onset, risk factors and causative agents of laboratory confirmed blood stream (LBCI) as a HAI in a level-2 NICU at RD Gardi Medical College, Ujjain, India. The diagnosis of HAI was established using the Centre for Disease Control, USA criteria. A predesigned questionnaire containing risk factors associated with BSHAI was filled. A total of 150 neonates (43% preterm) were included in the study. The incidence of LBCI was 31%; 56% of which was late onset sepsis. The independent risk factors for LBCI were: preterm (Odds Ratio OR 3.22), duration of NICU stay more than 14 days (OR 2.38), chorioamnionitis in the mother (OR 18.48), neonate born through meconium stained amniotic fluid (OR 4.53), mal-presentation (OR 10.58), endotracheal intubation (OR 11.60), umbilical catheterization (OR 15.11), HAI due to ventilator-associated pneumonia (VAP) (OR 11.88). Initiation of minimal enteral nutrition was protective (OR 0.15). The predominant causative organisms were Gram-negative pathogens (58%). Among Klebsiella spp. and E. coli isolates, 73 and 80%, respectively were identified as extended-spectrum beta-lactamase producers. The results can be used to identify high-risk neonates for LBCI.

Very little is known about laboratory confirmed blood stream infections (LCBIs) in neonatal intensive care units (NICUs) in resource-limited settings. The aim of this cohort study was to determine the incidence, risk factors, and causative agents of LCBIs in a level-2 NICU in India. The diagnosis of LCBIs was established using the Centre for Disease Control, USA criteria. A predesigned questionnaire containing risk factors associated with LCBIs was filled-in. A total of 150 neonates (43% preterm) were included in the study. The overall incidence of LCBIs was 31%. The independent risk factors for LCBIs were: preterm neonates (relative risk (RR) 2.23), duration of NICU stay more than 14 days (RR 1.75), chorioamnionitis in the mother (RR 3.18), premature rupture of membrane in mothers (RR 2.32), neonate born through meconium-stained amniotic fluid (RR 2.32), malpresentation (RR 3.05), endotracheal intubation (RR 3.41), umbilical catheterization (RR 4.18), and ventilator-associated pneumonia (RR 3.17). The initiation of minimal enteral nutrition was protective from LCBIs (RR 0.22). The predominant causative organisms were gram-negative pathogens (58%). The results of the present study can be used to design antibiotic interventions to reduce LCBIs in resource-limited settings.

Objectives: Acinetobacter baumannii is a causative pathogen of various healthcare-associated infections (HAIs) and is particularly prevalent in high-risk hospital settings. This study aimed to determine risk factors associated with HAIs caused by carbapenem-resistant A. baumannii (CRAB) in a neonatal intensive care unit (NICU). Methods: This prospective study was performed between January 2013 and June 2014 among NICU patients at the Mansoura University Children’s Hospital, Mansoura, Egypt. Neonates who developed HAIs due to CRAB were assigned to a case group, while those infected with carbapenem-sensitive A. baumannii (CSAB) were assigned to a control group. Results: Among the 124 neonates who developed A. baumannii-caused HAIs during the study period, 91 (73.4%) were caused by CRAB and 33 (26.6%) were caused by CSAB. Prematurity, premature rupture of the membranes (PROM), a previous stay in another hospital, prolonged NICU stay, the presence of invasive devices, previous exposure to carbapenems or aminoglycosides and prolonged antibiotic therapy before infection were significantly associated with CRAB-caused HAIs. A multivariate logistic regression analysis identified prematurity (adjusted odds ratio [aOR] = 25.3; P <0.01), mechanical ventilation (aOR = 18.9; P <0.01) and the previous use of carbapenems (aOR = 124.7; P <0.01) or aminoglycosides (aOR = 22.6; P = 0.04) to be independent risk factors for CRAB infections. Conclusion: Various risk factors were significantly associated with CRAB-caused HAIs among the studied NICU patients.

Abstract Background: Carbapenem-resistant Klebsiella pneumoniae bloodstream infections (CRKP-BSIs) are associated with high morbidity and mortality rates, especially in critically ill patients. Comprehensive mortality risk analyses and therapeutic assessment in real-world practice are beneficial to guide individual treatment.Methods: We retrospectively analyzed 87 patients with CRKP-BSIs (between July 2016 and June 2020) to identify the independent risk factors for 28-day all-cause mortality. The therapeutic efficacies of tigecycline-and polymyxin B-based therapies were analyzed.Results: The 28-day all-cause mortality and in-hospital mortality rates were 52.87% and 67.82%, respectively, arising predominantly from intra-abdominal (56.32%) and respiratory tract infections (21.84%). A multivariate analysis showed that 28-day all-cause mortality was independently associated with the patient’s APACHE II score (p = 0.002) and presence of septic shock at BSI onset (p = 0.006). All-cause mortality was not significantly different between patients receiving tigecycline- or polymyxin B-based therapy (55.81% vs. 53.85%, p = 0.873), and between subgroups mortality rates were also similar. Conclusions: Critical illness indicators (APACHE II scores and presence of septic shock at BSI onset) were independent risk factors for 28-day all-cause mortality. There was no significant difference between tigecycline- and polymyxin B-based therapy outcomes. Prompt and appropriate infection control should be implemented to prevent CRKP infections.

Objective: To evaluate carbapenem resistance and to detect blaOXA-23 and blaOXA-51 genes in carbapenem-resistant acinetobacter baumanii isolates recovered from patients having pneumonia secondry to ventilation. Methods: The cross-sectional study was conducted from July 2017 to June 2018 at the Department of Microbiology, University of Health Sciences, Lahore, Pakistan, and comprised endotracheal aspirates / tracheobroncheal lavage samples from patients irrespective of age and gender who developed pneumonia after being on the ventilator for 48 hrs at the Combined Military Hospital, and Jinnah Hospital, Lahore.  The samples were inoculated on MacConkey and blood agar and aerobically incubated at a temperature of 370C for 18-24 hours. The isolated organisms were further assessed by standard morphological, cultural and biochemical profile. Antibiotic susceptibility was done by Kirby-Bauer disc diffusion method. Carbapenem-resistant acinetobacter baumannii were checked for carbapenemase production using Modified Hodge Test. Conventional polymerase chain reaction and agarose gel electrophoreses were performed to detect blaOXA-23 and blaOXA-51 genes. Data was analysed using SPSS 17. Results: Out of 157 samples, 92(58.6%) yielded growth of bacteria, and, among them, 39(42.4%) were identified as acinetobacter baumannii. All (100%) acinetobacter baumannii cases showed resistance to carbapenem, were producing carbapenemase enzyme, and were positive for blaOXA-51 gene. The blaOXA-23 gene was amplified in 38(97.4%) isolates. Conclusion: BlaOXA-23 gene appeared to be the major cause of carbapenem resistance. Continuous...

Background: Incidence of multidrug resistant Klebsiella pnumoniae infections are increasing globally especially in ICUs. Aim: We evaluated the burden of colistin resistant K. pneumoniae (ColR KP) and the risk factors associated with the outcome of these patients. Methods: Consecutive patients developing K. pneumoniae infections were included. K. pneumoniae from endotracheal tube and catheterized urine sample, having cell count <105 cfu/ml, and which did not necessitate a change in antibiotics as per the treating physicians was considered as colonizer. Demographic and clinical details were collected and samples were processed as per standard protocol. Any growth was identified and its antimicrobial susceptibility was carried out by using Vitek 2 automated system. Minimum inhibitory concentration of >4 μg/ml for Colistin was considered as resistant. The resistant isolates were confirmed with Broth microdilution method. Risk factor associated with the outcome of ColR KP was analyzed. Findings: Burden of K. pneumoniae infection was 50.02 per 1000 admissions. K. pneumonie (n=155) was isolated from patients with ventilator associated pneumonia (84, 54.2%), followed by blood stream infection (49, 31.6%) and urinary tract infection (22, 14.2%). ColR KP and intermediate (ColI KP) isolates were 58 (37.41%) and 97 (62.6%) respectively. Among ColR KP infected patients 32 (55.1%) died whereas 26 (44.8%) patients were discharged. Higher mortality was witnessed in ColI KP cases (75, 77.3%) compared to ColR-KP cases (32, 55.1%) (p=0.004; OR=2.77; 95% CI=1.37 to 5.59). Colistin resistance and presence of central line were independently associated with mortality. Conclusion: Colistin resistant K. pneumoniae infections among ICU patients are on rise. Presence of central venous catheter and resistance to colistin were independent predictors of mortality.
