Thyroid storm is a rare, life-threatening condition in children. We report the case of a 16-year-old girl who presented with fever, cough, chest pain, and breathing difficulty. On the initial evaluation, a working diagnosis of left-sided pneumonia with empyema was made. She also had persistent tachycardia which was out of proportion to fever, and a staring look. She was found to have a thyroid storm. Timely diagnosis and appropriate management of thyroid storm proved to be lifesaving.
Background and Aims QCRP being acute phase reactant has predictable pattern of rise and fall following inflammation. Few studies have used QCRP for appropriateness of antibiotic therapy.To determine the difference in the magnitude of change in QCRP values from baseline to 48 h in subjects with culture positive neonatal sepsis receiving sensitive antibiotics (CPSA) versus those receiving resistant antibiotics (CPRA). Methods Neonates < twenty-eight days with suspected sepsis and baseline QCRP >10 mg/L were enrolled. Serum samples at 24, 36 and 48 h after initiation of antibiotics were analyzed for QCRP (PETIA: Particle enhanced turbidimetric immunoassay). After collecting blood culture [BD BACTEC TM Peds Plus/F] report, CPSA and CPRA were cases and sterile cultures were controls. Mann-Whitney U test, linear regression, ROC curve and Youden's index were used to measure appropriateness of antibiotic therapy. Results In one hundred forty-one sepsis episodes forty-five were CPSA, forty-four were CPRA and fifty two were culture sterile. The difference in QCRP between CPSA and CPRA was significant at all time points (p<0.001). The area under ROC curve was highest for If ΔCRP 0-48 was > 6.2 mg/L, the infant was likely to be getting sensitive antibiotics (sensitivity 86%, specificity 84%). Conclusion A decrease in serum QCRP by 6.2 mg/L can be used as a useful indicator of the appropriateness of antibiotics in neonatal sepsis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
