I have two comments on the interesting study by Jajoo et al.
First, Jajoo et al. addressed that the incidence of early-onset neonatal sepsis (EONS) was 18/1000 patient. Low birth weight (68%), prematurity (46%), and poor hygiene/cord care (46%) were common risk factors while lethargy/refusal to feed (77%), hypothermia (47.5%), and respiratory distress (44%) were common clinical presentations. Sepsis screen and blood culture were positive in 57% and 18%, respectively. Klebsiella pneumonia (36%), Staphylococcus aureus (21%), and Escherichia More Details coli (14%) were common organisms. Case fatality rate was 14%. I presume that the aforementioned results should be cautiously taken owing to the presence of the following three limitations. (1) The study population was small (n = 82). (2) The study period was short (1 year). (3) There was a methodological limitation related to the diagnostic algorithm used in the study to diagnosis sepsis. Jajoo et al. employed the following work-up. Sepsis screen and cultures (blood/urine/cerebrospinal fluid), tracheal aspirate, and chest X-ray were taken prior to the administration of antibiotics. Sepsis screen included total leukocyte count (TLC) and differential count, absolute neutrophil count (ANC), C-reactive protein (CRP), and immature to total neutrophil (I/TN) ratio. Sepsis screen was considered positive when any two of the following laboratory criteria were present: TLC <5000/mm 3, I/TN ratio 0.2, ANC <1800, and positive CRP >10 mg/dL. I presume that such sepsis work-up could not detect precisely all cases of EONS. This is based on the observation that the diagnosis of neonatal sepsis (NS) is a challenge due to nonspecific clinical signs and the fact that infection markers are difficult to interpret in thefirst and critical phase of NS. Accordingly, I presume that significant number of newborns included in Jajoo et al.'s study  were either over or underdiagnosed with EONS. Precise diagnosis of NS is in progress, and the recently published diagnostic work-up has shown that 16S rDNA polymerase chain reaction assay is more sensitive than blood culture. Moreover, the combination of markers (hs-CRP, procalcitonin [PCT], and interleukin [IL-6) was better than single markers to diagnose NS. In addition, PCT had greater diagnostic value than did hs-CRP and IL-6 while IL-6 was better for diagnosis of neonatal infection. I presume that constrained financial resources might curtail the implementation of the aforementioned sepsis work-up in India.
Second, Streptococcus agalactiae (SA) (previously called group B Streptococcus) is found in the digestive and vaginal tracts of 20–30% healthy individuals. It can infect the amniotic fluid before delivery or can infect the baby during delivery causing sepsis, pneumonia, or meningitis. Though intrapartum antibiotic prophylaxis (IPAP) protocol employed in many parts of the world has decreased the incidence of early-onset SA infection dramatically, it still remains a major cause of NS. To my knowledge, IPAP protocol is not yet widely implemented in the healthcare system in India. Hence, the nondetection of SA infection in Jajoo et al.'s study  is interesting and it might be attributed to the aforementioned limitations.
