Abstract

Background

We assessed the distribution of pneumococcal serotypes in children with microbiologically-confirmed invasive pneumococcal disease (IPD) before (2014-2015) and after (2016-2019) PCV10 introduction in Nepal in 2015.

Methods

Children (aged 2 months to <14 years) admitted to Patan Hospital, Nepal with pneumococcus detected in blood, CSF or pleural fluid were included. Serotyping was by Quellung method.

Results

Pre-vaccine, 6/22 (27.3%) IPD cases were age <2 years; post-vaccine, 5/36 (13.9%) were <2 years. Ratio of vaccine-type to non-vaccine-type IPD among <2y olds was 5:1 pre-vaccine and 2:3 post-vaccine; among >=2y olds, the ratio was 13:1 pre-vaccine and 7:1 post-vaccine. Most (32/41, 78%) vaccine-type IPD was serotype 1: 3/7 among <2 year olds (n=1 post-vaccine); 29/34 among >=2 year olds (n=17/19 post-vaccine were >4 years old). Among 44 IPD cases detected from blood, 36 (82%) were vaccine-type (n=29 were ST1), and 7 were non-vaccine-type (6C, 10A (n=2), 19A, 24F, 38, 41). Of 13 detected from CSF (1 culture, 3 PCR and 9 Binax-only), 5 were serotyped (1, 14, 6B, 6A/B, 7F) .The 3 pleural fluid cases were serotypes 1 (n=2) and 19A.

Conclusions

Post-PCV10 introduction, IPD among <2 year olds fell; although a high proportion of ST1 IPD remains, most were >4 years old.

Abstract

Background

S. pneumoniae is one of the most common causes of paediatric bacterial pneumonia. In low-income countries such as Nepal, CRP level and blood culture can be useful in diagnosis assessment. We assessed the association between CRP/blood culture, and pneumonia with end-point consolidation.

Methods

We included children less than 5 years of age admitted with suspected pneumonia to Patan Hospital in 2018 and 2019, whose chest xray, CRP level and blood culture were done. CRP levels >40 mg/dl were considered elevated.

Results

There was a significant difference (p<0.001) in CRP levels between EPC-pneumonia and non-EPC pneumonia cases with a median (IQR) CRP of 46.2 (16, 215) in 141 EPC-pneumonia cases and a median (IQR) CRP of 13 (4, 35) in non-EPC pneumonia cases. The sensitivity and specificity of CRP >40mg/dl to detect EPC pneumonia were 50% and 84% respectively. The area under the ROC curve was 0.727 indicating good discrimination between EPC-pneumonia and non-EPC pneumonia. Among the EPC-pneumonia cases, 62% had elevated CRP and 3.5% had S. pneumoniae positive blood cultures.

Conclusions

There was a significant association between CRP and EPC pneumonia. Blood culture had low sensitivity to detect bacterial pneumonia, nevertheless, CRP may be a useful tool in diagnosis of bacterial pneumonia.
