A statistically significant positive correlation was detected between PCT and CRP levels in patients with infectious fever (rho: 0.461; P = 0.003), but not in patients with central fever.
Fever was more common (65.2% vs. 32.0%, p = 0.004), C-reactive protein (CRP) was higher (31.5 ± 39.4 mg/L vs. 17.5 ± 32.2 mg/L, p = 0.038), and diffusion capacity for carbon monoxide (DLCO) % predicted was lower (45.9 ± 14.2% vs. 57.6 ± 18.5%, p = 0.050) in relapse group compared to nonrelapse group.
Plasma concentrations of markers of endothelial (Angpt-2, sFlt-1, sVCAM-1, sICAM-1) and immune (sTREM-1, IL-6, IL-8, CHI3L1, sTNFR1, PCT, CRP) activation pathways were determined in consecutive adults with acute fever (>38°C) at presentation to outpatient clinics in Dar es Salaam, Tanzania.
Any modification of the WBC count associated with an elevation of CRP (> 40 mg/L) or fever (> 38.5 °C) showed a high specificity for the diagnosis of infection.
High Concentration of C-Reactive Protein Is Associated With Serious Bacterial Infection in Previously Healthy Children Aged 3 to 36 Months With Fever and Extreme Leukocytosis.
Factors, such as enlarged liver, spleen and lymph nodes, digestive system involvement, low hemoglobin, leukopenia, CRP, decreased albumin, anti-dsDNA antibody, glucocorticoids, and cyclophosphamide, were independent risk factors for noninfectious fever in SLE.
Patients in the noninsect bite group more commonly had fever at presentation (P < 0.001), with increased white blood cell and C reactive protein values (both P < 0.001).
Antibiotic prescription for respiratory tract infections, the most common infection type, in children without comorbidities was most variable across countries (15-67% for upper respiratory tract infections and 24-87% for lower respiratory tract infections) and was associated with age (odds ratio [OR] 1·51, 95% CI 1·08-2·13), fever duration (OR 1·45, 1·01-2·07), blood concentrations of C-reactive protein (OR 2·31, 1·67-3·19), and chest x-ray results (OR 10·62, 5·65-19·94, for focal abnormalities; OR 3·49, 1·59-7·64, for diffuse abnormalities).
Fever disappearance and CRP normalization within 4 weeks were reported more frequently in patients receiving intravenous antibiotics (17/20 vs. 9/19, p<0.05).
The univariate analysis revealed a statistically significant difference between groups in preoperative fever (p = 0.032), stone burden (p < 0.001), C-reactive protein (p = 0.011), PCT (p < 0.001) and interleukin-6 (p = 0.035) levels.
Post-XRT findings included a second wave of fever and increased CRP and IL6, beginning 21 days after CAR T cells, which is late for cytokine-release syndrome from CAR T-cell therapy alone on this trial.
Values of PCT and CRP at fever onset as well as two days later were considered for analysis of their performance in distinguishing aetiologies of fever.
Patients with M pneumoniae-induced mucocutaneous disease had longer duration of prodromal fever (median [interquartile range], 10.5 [8.3-11.8] vs 7.0 [5.5-9.5] days; P = .02) and higher C-reactive protein levels (median [interquartile range], 31 [22-59] vs 16 [7-23] mg/L; P = .04) than patients with CAP due to M pneumoniae without mucocutaneous manifestations.
SLE patients with infections (n=13) showed a significantly higher incidence rate of fever (84.6 vs 28.2%) and serositis (84.6 vs 23.1%), increased level of erythrocyte sedimentation rate (60.5±30.1 vs 37.4±27.1 mm/h), serum C-reactive protein (CRP) (102.7±94.9 vs 9.4±14.9 mg/L), procalcitonin (PCT) (1.07±0.08 vs 0.16±0.13 μg/L), and lower blood hemoglobin (Hb) (93.0±20.5 vs 110.4±16.0 g/L) level compared with non-infection patients (n=39) (all P<0.05).
We validated a clinical prediction rule for <i>Legionella</i> based on clinical parameters (dry cough, fever) and laboratory findings (C-reactive protein, lactate dehydrogenase, sodium, platelet counts) in 713 consecutive patients with community-acquired pneumonia.
Children aged 2-59 months with fever and cough and without life-threatening conditions received an antibiotic based on a CRP-informed strategy (combination of CRP ≥80 mg/L plus age/temperature-corrected tachypnea and/or chest indrawing) or current World Health Organization standard (respiratory rate ≥50 breaths/minute).
The infant, born at 39 weeks of gestation by normal delivery, developed fever (38.5˚C) with the high serum C-reactive protein levels on the 1st day of life, and exhibited tachypnea on the 3rd day.
