Laboratory abnormalities in patients with bacterial pneumonia

Area of Science:

• Clinical Medicine
• Biochemistry
• Infectious Diseases

Background:

• Bacterial pneumonia is a significant cause of morbidity and mortality.
• Identifying predictors of severity is crucial for effective patient management.
• Laboratory abnormalities may offer insights into disease severity.

Purpose of the Study:

• To evaluate laboratory abnormalities as predictors of illness severity in bacterial pneumonia.
• To compare laboratory findings between pneumonia patients and a control group.
• To identify specific laboratory markers associated with worse outcomes.

Main Methods:

• Retrospective analysis of 302 bacterial pneumonia patients admitted to a tertiary care hospital.
• Patients were categorized based on serum phosphorus levels: hypophosphatemia (< or = 2.4 mg/dL) and normophosphatemia (> 2.4 mg/dL).
• Comparison of laboratory data, mortality, and hospitalization duration between groups; logistic regression used to identify predictors.

Main Results:

• Hypophosphatemia was more prevalent in pneumonia patients (44.7%) than controls (10.3%).
• Pneumonia patients exhibited lower levels of calcium, phosphorus, albumin, cholesterol, and alanine aminotransferase.
• Hypophosphatemic pneumonia patients had lower potassium, calcium, albumin, and higher glucose and creatine phosphokinase levels, with longer hospital stays and higher mortality.

Conclusions:

• Hypophosphatemia, hypocalcemia, hypokalemia, and hypoalbuminemia are potential predictors of severity in bacterial pneumonia.
• These laboratory findings may indicate a more severe clinical course and increased risk.
• Early identification of these abnormalities can aid in risk stratification and management.
