C-reactive protein--an indicator of generalized bacterial infection in children with nephrotic syndrome
Insights
C-reactive protein (CRP) effectively distinguishes invasive bacterial infections from other infections in children with nephrotic syndrome. CRP levels remained reliable regardless of nephrotic syndrome activity, aiding diagnosis.
Area of Science:
- Pediatrics
- Infectious Diseases
- Nephrology
Background:
- Nephrotic syndrome increases susceptibility to infections.
- Accurate diagnosis of bacterial infections is crucial in these patients.
- C-reactive protein (CRP) is a potential biomarker for infection.
Purpose of the Study:
- To evaluate the utility of CRP in identifying bacterial infections in children with nephrotic syndrome.
- To determine if nephrotic syndrome activity affects CRP levels.
Main Methods:
- A study involving 12 children with nephrotic syndrome and 29 infection episodes.
- Measurement of C-reactive protein (CRP) levels during various infection types.
- Correlation of CRP values with infection severity (septic vs. superficial/focal).
Main Results:
- CRP levels were significantly higher in septic episodes (127-270 mg/l) compared to superficial/focal infections (<47 mg/l).
- CRP levels effectively differentiated invasive bacterial diseases from other infections.
- Nephrotic syndrome activity did not influence CRP levels.
Conclusions:
- C-reactive protein is a valuable tool for detecting invasive bacterial infections in pediatric nephrotic syndrome.
- CRP can reliably discriminate bacterial infections irrespective of the underlying nephrotic condition.
Abstract:
The usefulness of C-reactive protein for detecting bacterial infections in children with nephrotic syndrome was studied in 12 children who had a total of 29 episodes of infection. Four episodes were septic, with CRP values of 127-270 mg/l and 25 superficial or focal with all CRP values below 47 mg/l; 13 were below 10 mg/l. CRP thus discriminated the invasive bacterial diseases from other infections. It was not affected by the nephrotic syndrome activity.
