Role of C-Reactive Protein and Procalcitonin in Differentiation of Tuberculosis from Bacterial Community Acquired Pneumonia

Objective: In this study, we aimed to explore the role of the plasma presepsin level in patients with community-acquired pneumonia during admission to the emergency department in assessing the diagnosis, severity, and prognosis of the disease. In addition, we wanted to investigate the relationship of presepsinin with procalcitonin, C-reactive protein and pneumonia severity scores. Methods: One hundred twenty-three patients over the age of 18 who presented with a diagnosis of pneumonia to the emergency department were included in the study. The vital signs, symptoms, examination findings, background information, laboratory results, and radiological imaging results of the patients were recorded. The 30-day mortality rates of the patients were determined. Results: A statistically significant difference was found between the presepsin levels of the patients diagnosed with pneumonia and those of healthy subjects (p < 0.05). The plasma presepsin levels of the patients who died (8.63 ± 6.46) were significantly higher than those of the patients who lived (5.82 ± 5.97) (p < 0.05). The plasma procalcitonin and C-reactive protein levels of the dead patients were significantly higher than those living (p < 0.05). A presepsin cut-off value of 3.3 ng/mL for 30-day mortality was established (AUROC, 0.65; specificity, 45%; sensitivity, 82%). Procalcitonin is the most successful biomarker in the determination of mortality (AUROC, 0.70). A significant correlation was available between presepsin and lactate, C-reactive protein and procalcitonin (p < 0.05). There was a significant correlation between the Pneumonia Severity Index values and presepsin levels (p < 0.001, r = 0.311). Conclusion: The plasma presepsin level can be utilized for diagnosing community-acquired pneumonia. Plasma presepsin, procalcitonin and C-reactive protein levels can be used to predict the severity and mortality of community-acquired pneumonia.

BACKGROUND:In recent outbreak of COVID-19 infection,the risk of thrombosis should be concerned.We observed dynamic changes of D-Dimer level,C-Reactive Protein(CRP) level and Venous Thromboembolism risk assessment score(VTE score) during active disease.We included patients of conrmed covid-19 patients who were RT-PCR positive and patients of community acquired pneumonia(CAP) who were conrmed by CT-SCAN ndings.We observed correlation of D-dimer level with both CRP level & VTE score. METHOD:We examined the clinical laboratory result of 50 patients with conrmed COVID-19 positive patients and 50 patients with community acquired pneumonia(CAP).We analysed D-dimer level of this patients by Automated Coagulometer-STAGO in our hematological laboratory and CRP level by latex method.We use pauda prediction score to identify patients at high risk for venous thrombo embolism.We observed D-dimer level of all patients with their correlation to CRP level & VTE score.S RESULT:On admission,Both COVID-19 and CAP patients,D-dimer level were increased,more increased in COVID-19 patient compare to CAP patient. D-dimer level were related to inammatory marker,mainly with CRP level.There was low correlation between VTE score & Ddimer levels weakened the role of D-dimer in the prediction of thrombosis. CONCLUSION:Elevated baseline D-dimer levels are associated with inammation but not with VTE score in COVID patients,So we can't judge whether anticoagulation is needed only according to D-dimer levels. Abnormal D-dimer level with inammatory factors suggest that anticoagulant therapy might be needed.

Lung cavities are not typically associated with community-acquired pneumonia (CAP). CAP due to P. aeruginosa is rare and even less commonly causes necrotizing pneumonia. We report a case of P. aeruginosa CAP that progressed to necrotizing pneumonia and was eventually fatal. Procalcitonin (PCT) has been well investigated in guiding antibiotic therapy (especially CAP) in adults. In this case, PCT at presentation and sequentially was negative. We discuss this caveat and present hypotheses as to the sensitivity and specificity of PCT and C-reactive protein (CRP) in these patients. To better characterize P. aeruginosa CAP, we undertook a review of cases indexed in PubMed from 2001 to 2016 (n=9). The data reveal that risk factors for P. aeruginosa CAP include smoking, alcohol use, obstructive lung disease, sinusitis, and hot tub use. The route of infection for P. aeruginosa CAP remains unknown. One of the most interesting findings on reviewing cases was that P. aeruginosa CAP involves the right upper lobe in the vast majority. We suggest that when physicians in the community see patients with distinctly upper lobe necrotizing or cavitary pneumonia, they should consider P. aeruginosa in their differential diagnosis. Further studies are needed to clarify route of infection, role of PCT and CRP, and optimal therapy including drug and duration.
