Background: Neonatal infections are the commonest cause of neonatal mortality along with perinatal asphyxia and consequence of Prematurity and Low Birth Weight (LBW) in Bangladesh. Early Onset Neonatal Sepsis (EONS) is neonatal sepsis occurring within the first 72 hours of birth and it is much more fulminant and has a higher mortality than Late Onset Sepsis (LOS). Sepsis in neonate remains a significant cause of mortality and morbidity in developing countries. Changing bacterial flora and emergence of resistant strains adds to the problem. Thus, neonatal sepsis requires accurate and timely clinical and laboratory diagnosis and proper management for better outcome. The organisms responsible for Early Onset Sepsis (EOS) are different than Late Onset Sepsis (LOS). In this study an attempt has been made to know the positivity rate of EOS and profile of bacteria responsible for EOS and determine the antimicrobial sensitivity pattern that were investigated for rule out sepsis. Methods: This was a prospective observation single centre study over a period of nine months (January to September, 2017) conducted on neonates born at Ad-din Medical College Hospital (AMCH), Dhaka and subsequently admitted in Neonatal Intensive Care Unit (NICU) within 72 hours of birth that were investigated for rule out sepsis. Dual blood sample for cultures from separate area along with essential investigations were sent by collecting samples under aseptic precautions. Empirical antimicrobial therapy was started according to antimicrobial guidelines in the NICU. The blood cultures test were carried out by BD BACTEC automated blood culture system and susceptibility testing was done for all blood culture isolates according to the criteria of the National Committee for Clinical Laboratory Standards by disk diffusion method. Results: A total of 700 neonates were investigated to rule out sepsis and 5.43% neonates were found with culture proven sepsis in the study. The gram positive bacteria accounted for 71% and gram negative 29% of the total isolates. Out of total 38 isolates, Coagulase-Negative Staphylococci (CONS) (68.4%) was the commonest followed by Acinetobacter (18.4%) and E. coli (7.9%) was common culture isolates. Among the gram positive, CONS (96.3%) was commonest isolate and in gram negative Acinetobacter (63.6%) was the most prevalent bacteria followed by E.coli (27.3%). Gram positive isolate, especially CONS (68.4%) was the major culprit for the early onset sepsis. Among the commonly used antibiotics, the susceptibilities were remarkably low to Amikacin (16%) in comparison to Ampicillin (42%) Cefotaxime (45%) and moderately high to Gentamicin (58%) for both gram positive & gram negative isolates. All (100%) gram positive isolates were resistant to Amikacin. Majority of the gram positive showed low susceptibilities to Meropenem (22%) Ciprofloxacin (41%) Ampicillin (48%) & Oxacillin (48%) in comparison to Cefotaxime (52%) Levofloxacin (55%) Gentamicin (70%), Linezolid (70%) and Vancomycin (74%). 50% of Coagulase Negative Staphylococcus (CONS) were resistant to Methicillin/Oxacillin. The sensitivity pattern of majority of gram negative isolates showed high level of resistance to Piperacillin+Tazobacterm (9%) and Ampicillin (27%) Gentamicin (27%) Cefotaxime (27%) less sensitive to Ciprofloxacin (45%); moderately high to Levofloxacin (54%) & Amikacin (54%) and highly sensitive to Imipenem/Meropenem (73%) & Colistin (91%). Gentamicin (58%) and Levofloxacin (55%) were showed marginal superiority compared to Ampicillin (42%) and Cefotaxime (45%) for effective coverage of both. Conclusion: Present study indicated that gram positive species especially CONS continue to be the predominant causative organism followed by Acinetobacter and E. coli in gram negative species. The antibiotic susceptibility profile suggested that for a given cohort empiric (initial) choice of Ampicillin and Gentamicin in EOS. Routine bacterial surveillance and their sensitivity patterns must be an essential component of neonatal care Chatt Maa Shi Hosp Med Coll J; Vol.17 (1); Jan 2018; Page 3-8

Background: Neonatal sepsis is a leading cause of neonatal mortality and continues to be a formidable problem for neonatologists and pediatricians world over.  Knowledge of microbial flora and their susceptibility will help us to decide empirical treatment for the neonatal sepsis. The objective of this study was to determine the bacteriological flora prevalent in NICU and the antimicrobial sensitivity pattern.Methods: The blood culture reports of all the neonates with culture proven neonatal sepsis during the period July 2010 to September 2013 were reviewed retrospectively. A retrospective review in tertiary care teaching medical college. The data was entered in Excel sheets and percentages of various outcomes were calculated.Results: A total of 28,927 babies were born during the study period and 336 among them had positive blood culture. The incidence of neonatal sepsis was 11.62 per 1,000 live births. Three hundred fifty- six microbes were isolated, out of which 50% presented as early onset sepsis and remaining as late onset sepsis. Pseudomonas aeruginosa was the most common organism encountered in both early (43.82%) and late onset sepsis (51.35%). Gram negative bacilli were sensitive to carbapenems (92%) followed by piperacillin-tazobactam (90%) whereas linezolid (90%) was most sensitive antimicrobial for gram positive cocci.Conclusions: Pseudomonas was most commonly isolated in both early and late onset sepsis.  Gram negative bacilli were most sensitive to piperacillin-tazobactam and the carbapenems whereas linezolid and vancomycin were most effective against the gram-positive cocci. Resistance to third generation cephalosporins was rampant. Continuous surveillance for microbial flora, their antibiotic susceptibility, rational use of antibiotics and the strategy of antibiotic cycling may be of help to curtail emerging antimicrobial resistance.

Neonatal sepsis is a major cause of mortality and morbidity in newborn. The spectrum of bacteria which causes neonatal sepsis varies in different parts of the world. The organisms responsible for early onset and late onset sepsis are different. The objective of the study was undertaken to determine the pattern of bacterial isolates responsible for early and late onset neonatal sepsis. A prospective descriptive study over the period of one year was conducted at the Department of Neonatal Intensive care unit of Ad-din Women’s Medical College and Hospital, Dhaka, Bangladesh.Organisms were isolated from 8.7% of collected blood samples. The male female ratio of culture proven sepsis was 1.7:1. More than half (52.8%) of the evaluated neonates were preterm. & 56.3% had low birth weight. The gram positive and gram negative bacteria accounted for 24.1% and 75.9% of the isolates respectively. Around three fourth of the neonates (75.8%) presented with early onset sepsis, while 24.2% presented with late onset sepsis. Acinetobacter was the most common pathogen both in early onset (70%) and late onset (30%) sepsis. Pseudomonas (89.4%) was the second most common pathogen in early onset sepsis. Total mortality rate was 5.7%. Pre term, low birth weight and gram negative sepsis contributes majority of mortality.Gram negative organism especially Acinetobacter found to be commonest cause of sepsis. Pseudomonas was second most common but contributed highest in late onset sepsis and neonatal death due to sepsis.

Neonatal sepsis is a major cause of mortality and morbidity in newborn, particularly in developing countries. The spectrum of bacteria which causes neonatal sepsis varies in different parts of the world. The organisms responsible for early onset and late onset sepsis are different. The objective of the study was undertaken to determine the pattern of bacterial isolates responsible for early and late onset neonatal sepsis based on the presence of one or more clinical signs, and its outcome. A cross- sectional prospective study was carried out in the special care baby unit (SCABU) from November 2008 to September 2009 under department of Paediatrics and Neonatology, BIRDEM General Hospital, Dhaka, Bangladesh. Organisms were isolated from 8.9% of collected blood samples. The male female ratio of culture proven sepsis was 1.7:1. Most of the culture proven septic neonates(71.88%) were preterm & 65.63% had low birth weight. The most frequent clinical presentations of patients with culture-proven sepsis were poor moro reflex (92.2%), feeding intolerance (90.6%), jaundice (87.5%), abdominal distention (76.6%), and lathergy (73.4%). The Gram positive and Gram negative bacteria accounted for 6 (9.4% ) and 58 (90.6%) of the isolates respectively. Around two third of the culture-proven septic neonates (70.3%) presented with early onset sepsis, while 29.7% presented with late onset sepsis. Klebsiella pneumoniae was the most common pathogen both in early onset (31.25%) and late onset (6.25%) sepsis. Serratia (18.75%) was the second most common pathogen in early onset sepsis. Total mortality rate was 9.38%. Preterm, low birth weight and Gram negative sepsis contributes majority of mortality. Gram negative organism especially Klebsiella pneumoniae contributed highest in early onset sepsis and neonatal death (6.25%) due to sepsis.

Neonatal sepsis is of two types; early onset sepsis and late onset sepsis. Early onset sepsis (EOS) present within first 72 hours of life. In severe cases, the neonates may be symptomatic at birth. Infants with EOS usually present with respiratory distress and pneumonia. Hence based on above findings the present study was planned to evaluate the immediate clinical outcomes of culture proven neonatal sepsis in the NICU. The study was planned by enrolling the 320 neonates admitted in Neonatal unit of Department of Paediatrics in Nalanda Medical College and Hospital, Patna, from Dec 2017 to Jun 2018. The 40 neonates were diagnosed positive for septicemia was enrolled in the present study.  The approval of the institutional committee was taken prior conduct of study. All the patients were informed consents. The data from the present study revealed that adequate care of the low birth weight babies is of utmost importance to prevent infection by Klebsiella pneumoniae. Amikacin should be used along with third-generation cephalosporins for empirical treatment of gram-negative neonatal sepsis. This empirical regimen should be modified later based on the antibiogram of the isolates. Keywords: neonatal sepsis, epidemiology, microbiology, etc.

A Prospective Study

About 20 % of neonates develop sepsis and among them approximately 1% die due to sepsis-related causes. Bacterial pathogens are the commonest cause of neonatal sepsis which is either early-onset (<72 hours of age) or late-onset (>72 hours). Little is known about the epidemiology and antimicrobial susceptibility pattern of sepsis causing bacterial pathogens in Nepal. A prospective study was carried out among neonates suspected to have sepsis and admitted to Tribhuwan University Teaching Hospital from January to December 2016. Clinical suspicion of sepsis was made based on clinical findings and laboratory parameters, later confirmed by isolation of organisms in blood culture. Drug resistance pattern of Gram-positive and Gram-negative bacteria were studied by standard methods. Meropenem resistant Gram-negative bacteria were processed for the detection of β-lactamases and resistant genes were detected by X-pert Carba-R (Cepheid) Assays. Of 372 neonates with clinically suspected sepsis, 132 (35.4%) had blood culture positivity, with 47% early-onset and 53% late-onset sepsis. Coagulase-negative Staphylococcus aureus (CONS) was the most common (37.9%) etiological agent followed by Klebsiella pneumoniae (12.9%). Of all 132 isolates, 81 (61.3%) were Gram-positive of which 22 (27.2%) were multi-drug resistant (MDR), three (3.7%) were methicillin-resistant S. aureus (MRSA), and 14 (17.2%) were methicillin-resistant CoNS; and 50 (37.8%) were Gram-negative of which 26 (52%) were MDR and 29 (58%) were resistant to β-lactamases. The blaKPC gene was detected in four isolates of K. pneumoniae, two of E. coli, one ABC (Acinetobacter baumanii complex), and one Enterobacter aerogenes whereas blaNDM gene was detected in one isolate of K. pneumoniae, two of E. coli, two Pseudomonas aeruginosa, one Acinetobacter baumanii complex, and one Enterobacter aerogenes. Overall mortality due to sepsis-related causes was 7.6% (10 of 132). One-third of clinically suspected neonatal sepsis cases were culture positive. Late-onset sepsis was more common than early onset. CoNS was the predominant bacterial isolate followed by Klebsiella pneumoniae, with high rates of multi-drug resistance.

Introduction: India has the highest incidence of clinical sepsis i.e.17,000/ 1,00,000 live births. In Neonatal sepsis septicaemia, pneumonia, meningitis, osteomyelitis, arthritis and urinary tract infections can be included. Mortality in the neonatal period each year account for 41% (3.6 million) of all deaths in children under 5 years and most of these deaths occur in low income countries and about one million of these deaths are due to infectious causes including neonatal sepsis, meningitis, and pneumonia. In early onset neonatal sepsis (EOS) Clinical features are non-specific and are inefficient for identifying neonates with early-onset sepsis. Culture results take up to 48 hours and may give false-positive or low-yield results because of the antenatal antibiotic exposure. Reviews of risk factors has been used globally to guide the development of management guidelines for neonatal sepsis, and it is similarly recommended that such evidence be used to inform guideline development for management of neonatal sepsis. Material and Methods: This study was carried out using institution based cross section study . The total number neonates admitted in the hospital in given study period was 644, of which 234 were diagnosed for neonatal sepsis by the treating pediatrician based on the signs and symptoms during admission. The data was collected: Sociodemographic characteristics; maternal information; and neonatal information for neonatal sepsis like neonatal age on admission, sex, gestational age, birth weight, crying immediately at birth, and resuscitation at birth. Results: Out of 644 neonates admitted 234 (36.34%) were diagnosed for neonatal sepsis by the paediatrician based on the signs and symptoms during admission. Of the 234 neonates, 189 (80.77%) infants were in the age range of 0 to 7 days (Early onset sepsis) while 45 (19.23%) were aged between 8 and 28 days (Late onset sepsis). Male to female ratio in our study was 53.8% and 46% respectively. Out of total 126 male neonates 91(72.2%) were having early onset sepsis while 35 (27.8%) were late onset type. Out of total 108 female neonates 89(82.4%) were having early onset sepsis while 19 (17.6%) were late onset type. Maternal risk factors were identified in 103(57.2%) of early onset sepsis cases while in late onset sepsis cases were 11(20.4%). Foul smelling liquor in early onset sepsis and in late onset sepsis was 10(5.56%) and 2 (3.70%) respectively. In early onset sepsis cases maternal UTI, Meconium stained amniotic fluid, Multipara and Premature rupture of membrane was seen in 21(11.67%), 19 (10.56%), 20(11.11%) and 33 (18.33%) cases respectively. In late onset sepsis cases maternal UTI, Meconium stained amniotic fluid, Multipara and Premature rupture of membrane was seen in 2 (3.70%), 1(1.85%), 3 (5.56%) and 3 (5.56%) cases respectively. Conclusion: Maternal risk identification may help in the early identification and empirical antibiotic treatment in neonatal sepsis and thus mortality and morbidity can be reduced.

Background: Neonatal sepsis is the commonest cause of neonatal mortality responsible for about 30-50% of total neonatal deaths in developing countries. Surveillance of causative organisms and their antibiotic sensitivity pattern promotes rational use of antibiotics and antibiotic stewardship.Methods: A retrospective study, relevant data regarding the neonates diagnosed with culture positive sepsis was obtained from the case records during the period from July 2014 to June 2017. Culture positive sepsis was defined as isolation of bacterial pathogen from blood in neonates with clinical suspicion of sepsis.Results: Of the 414 neonates with clinical suspicion of sepsis, 110 neonates had blood culture positive sepsis. Sepsis was predominant in males (64.5%). Low birth weight (47.2%) and prematurity (40.9 %) were important neonatal risk factors for sepsis. Early onset sepsis occurred in 58.1% of the cases and late onset sepsis in 41.9% of the neonates. Gram-positive cocci constituted 67.52% of all isolates and gram negative 30.76%. The most frequently isolated organism in blood was methicillin resistant coagulase negative staphylococcus(MRCONS) (32.47%). Gram positive organisms included MRCONS, methicillin resistant Staphylococci aureus (MRSA), group B Streptococci (GBS), Staphylococcus aureus and Enterococci. Among Gram-negative organisms, Acinetobacter was most frequently isolated followed by Klebsiella, Escherichia coli, Pseudomonas, Citrobacter and Burkholderia species. The mortality in the study group was 13.5%. Gram negative organisms were most resistant to ampicillin and cephalosporins. Gram positive isolates were least resistant to vancomycin and linezolid.Conclusions: Gram positive sepsis was the most common type of sepsis among the neonates, although mortality was more in gram negative sepsis.

Background: Neonatal sepsis refers to generalized bacterial blood stream infection in first 28 days of life documented by positive blood cultures. It is one of leading causes of neonatal mortality. Objectives was to study clinicobacteriological, antibiotic sensitivity patterns and mortality of neonatal sepsis.Methods: This prospective study was conducted in the Department of Pediatrics of Government Medical College Srinagar in collaboration with Department of Microbiology of same medical college after ethical clearance from ethical committee of Government Medical College Srinagar. One hundred (100) neonates out of 731 neonates admitted between octomber2007 and September 2008 with signs and symptoms of neonatal sepsis were included in our study by random sampling method. After history, examination and laboratory investigation blood culture results were analyzed by standard statistical methods.Results: The blood culture was positive in 40% of neonates. Fifty one (51) neonates were males while as 49 were females. Sixty three (63) neonates had late onset of sepsis while as 37 had early onset sepsis. The positive  blood culture was more common in males, late onset sepsis, babies born in rural areas, home born, vaginal births, preterm and other  low birth weight neonates .The gram negative isolates were most common followed by positive ones .The best sensitivity of gram negative isolates was to ciprofloxacin followed by amikacin and cephalosporins while as gram positive isolates were sensitive to imipenum followed by vancomycin. Pseudomonas was most responsive to pipercillin +tazobactum combination. The neonatal mortality was 35% being higher in early onset sepsis and low birth weights.Conclusions: This study depicts a high rate of neonatal sepsis, mainly caused by gram negative organisms followed by gram positive organisms with rising drug resistance that could bear far reaching implications to the times to come, mandating the implementation of sepsis preventive measures and administration of specific antibiotics.

Background: Sepsis is the second major cause of mortality among neonates. Present study was done to identify the common organisms which cause early and late onset neonatal sepsis in neonates admitted in our department and their antibiotic sensitivity patterns.Methods: All neonates weighing more than 1500 gms and born to mothers with pre-existing infection, admitted to neonatal intensive care unit for suspected neonatal sepsis were included in the present study. They underwent blood culture and antibiotic sensitivity profiling.Results: 210 newborns were admitted to the NICU of our department for suspected neonatal sepsis. Longer duration of rupture of membranes was found to be significantly associated with growth of organisms. Amongst the cases with gram positive organisms, most were due to Coagulase-negative staphylococci (CoNS) (n=25), followed by Staphylococcus aureus (n=14), and, Enterococcus (n=4). Gram negative organisms isolated constituted 17 organisms. Amongst the cases with gram negative organisms, mostly were due to Klebsiella (n=10), followed by Pseudomonas (n=5) and E. coli (n=2). The most common organism causing early onset sepsis was CoNS, while Staphylococcus aureus was the most common organism causing late onset sepsis. CoNS was fully sensitive to Vancomycin and Amikacin. Staphylococcus aureus was fully sensitive to Amikacin, α-hemolytic. Streptococcus were sensitive to Amikacin, Vancomycin and Piperacillin and Tazobactum and Enterococcus was sensitive to Amikacin and Vancomycin.Conclusions: Antimicrobial surveillance of neonatal septicaemia is required to know the antibiotic sensitivity pattern and thus to formulate policies on use of antibiotics and to know the changing spectrum of antimicrobial sensitivity patterns.
