Abstract
BACKGROUND Although it was originally unknown whether there would be cases of reinfection of coronavirus disease 2019 (COVID-19) as seen with other coronaviruses, cases of reinfection were reported from various regions recently. However, there is little information about reinfection in children. METHODS In this study, we aimed to investigate the incidence and clinical findings of reinfection in pediatric patients who had recovered from COVID-19. We retrospectively evaluated all patients under 18 years of age with COVID-19 infection from a total of eight healthcare facilities in Turkey, between March 2020 and July 2021. Possible reinfection was defined as a record of confirmed COVID-19 infection based on positive reverse transcription-polymerase chain reaction (RT-PCR) test results at least 3 months apart. RESULTS A possible reinfection was detected in 11 out of 8840 children, which yielded an incidence of 0.12%. The median duration between two episodes of COVID-19 was 196 (92-483) days. When initial and second episodes were compared, the rates of symptomatic and asymptomatic disease were similar for both, as was the severity of the disease (p = 1.000). Also, there was no significant difference in duration of symptoms (p = 0.498) or in hospitalization rates (p = 1.000). Only one patient died 15 days after PCR positivity, which resulted in a 9.1% mortality rate for cases of reinfection in pediatric patients. CONCLUSION We observed that children with COVID-19 were less likely to be exposed to reinfection when compared with adults. Although the clinical spectrum of reinfection was mostly similar to the first episode, we reported death of a healthy child during the reinfection.

Abstract
BACKGROUND In many cases of suspected sepsis, causative microorganisms cannot be isolated. Multiplex real-time PCR generates results more rapidly than conventional blood culture systems. METHODS In this study, we evaluated the diagnostic performance of multiplex real-time PCR (LightCycler® SeptiFast, Roche, Mannheim, Germany), and compared with blood cultures and cultures from focus of infection in nosocomial sepsis. RESULTS Seventy-eight nosocomial sepsis episodes in 67 adult patients were included in this study. The rates of microorganism detection by blood culture and PCR were 34.2% and 47.9%, respectively. Sixty-five microorganisms were detected by both methods from 78 sepsis episodes. Nineteen of these microorganisms were detected by both blood culture and PCR analysis from the same sepsis episode. There was statistically moderate concordance between the two methods (κ=0.445, P<0.001). There was no significant agreement between the blood culture and PCR analysis in terms of microorganism detected (κ=0.160, P=0.07). Comparison of the results of PCR and cultures from focus of infection revealed no significant agreement (κ=0.110, P=0.176). However, comparison of the results of PCR and blood cultures plus cultures from focus of infection (positive blood culture and/or positive culture from focus of infection) showed poor agreement (κ=0.17, P=0.026). When the blood culture was used as the gold standard, the sensitivity, specificity, positive and negative predictive value of PCR in patients with bacteremia was 80%, 69%, 57% and 87%, respectively. CONCLUSIONS SeptiFast may be useful when added to blood culture in the diagnosis and management of sepsis.
