Leukergy--a new diagnostic test for bone infection

Area of Science:

• Hematology
• Infectious Diseases
• Clinical Diagnostics

Background:

• Inflammatory diseases are often associated with white blood cell aggregation in peripheral blood, a phenomenon known as leukergy.
• Accurate and timely diagnosis of bone and joint infections is crucial for effective patient management and preventing complications.

Purpose of the Study:

• To evaluate the diagnostic and prognostic utility of a novel leukergy blood test for bone and joint infections.
• To compare the accuracy of the leukergy test with established hematological markers like ESR, white cell count, and blood culture.

Main Methods:

• The leukergy test was performed on 26 patients diagnosed with bone or joint infections.
• Assessed the correlation between the percentage of agglomerated white cells and clinical severity.
• Compared the test's performance against erythrocyte sedimentation rate (ESR), white cell count, and blood culture results.

Main Results:

• The leukergy test demonstrated high sensitivity, correctly identifying infection in 25 out of 26 patients.
• The test proved more accurate than ESR, white cell count, and blood culture in diagnosing bone and joint infections.
• The degree of white cell agglomeration correlated with the clinical severity of the infection.
• The leukergy test effectively detected reactivation of septic processes, outperforming other hematological tests.

Conclusions:

• The leukergy test is a rapid, inexpensive, and highly accurate method for diagnosing bone and joint infections.
• This novel diagnostic tool aids in monitoring infection severity and detecting disease recurrence.
• The leukergy test offers a valuable addition to the management of patients with bone and joint infections.
