Invasive pneumococcal disease (IPD) causes mortality in approximately 1 million children annually, a major part occurs in developing countries. We aimed to describe IPD spectrum, serotype distribution in relation to vaccine strains, antibiotic susceptibility and outcome in a private children's hospital in India.
This retrospective, observational study was conducted at a teaching hospital in Chennai from January 2018 to March 2019 after obtaining institute's ethical committee approval. Children were recruited based on IPD (CDC definition) and underwent medical history by interviewing the parents. Streptococcus pneumoniae isolated after antimicrobial susceptibility testing by VITEK 2 were serotyped by Quellung method at the pneumococcal WHO regional reference laboratory, CMC, Vellore.
A total of 33 confirmed IPD cases were enrolled in the study, of which twenty (61%) were males and 13 (39%) were females. The incidence of IPD was 2.3/1000 hospitalised children. Majority (48%) of the cases were <1 year old. Pneumonia (52%) contributed to majority of cases followed by bacteraemia (36%) and meningitis (12%). Nearly 79% of the infections were of vaccine types (major serotypes 19F [27%], 6B [21%], 23F [6%], 9V [6%] and 14 [6%]) and the rest 21% are nonvaccine types (2, 31, 15B, 15F, 11A, 18A and 25F) similar to earlier reports from South India.,,, Penicillin and cephalosporin resistance of 6% was seen in meningeal isolates. Antibiotic resistance is on an upsurge and is described in [Table 1]. Complications during the hospital stay which included empyema, ARDS, cerebral infarction, seizures, acute kidney injury and MODS were seen in 39%. Twenty-seven (82%) children were discharged well, 2 (6%) developed neurological deficits and four (12%) children succumbed. Proportional mortality rate was 3.2%, whereas case fatality rate was 12%.

Data on variability and rapid emergence of replacement pneumococcal serotypes are pivotal to introduce vaccines with wider coverage based on local epidemiological data. Pneumococcal vaccines have significantly decreased the incidence of IPD in developed countries, and the same needs to be introduced as a part of Universal Immunization Programme (UIP) all over India.
It is a single hospital-based study, which may underestimate the true number of cases in the region, and the data might not be representative of the entire country.
