Dr. Petr Kelbich | Investigating Inflammatory Conditions in Extravascular Body Fluids: An Important New Parameter

Jan 23, 2025 | Medical & Health Sciences

Diagnosing disorders of the brain and other organs can often feel like solving a challenging puzzle. Analyzing non-blood body fluids provides valuable clues that can help address this complexity. To enhance this process, Dr. Petr Kelbich from Jan Evangelista Purkyně University and Masaryk Hospital in Ústí nad Labem, Czech Republic, introduced an innovative method called Cytological-Energy Analysis.

At the core of this approach is the Coefficient of Energy Balance (KEB), a mathematical concept that offers deeper insights into immune cell activity and energy requirements during inflammation. By using this method, doctors can identify issues in different organs with greater precision, making diagnoses more accurate and efficient.

Dr. Kelbich initially introduced this method for diagnosing central nervous system (CNS) disorders through cerebrospinal fluid (CSF) analysis.

Cytological Investigation of CSF and the Coefficient of Energy Balance (KEB)

The first step of this method involves a cytological analysis of CSF. The cells found in CSF can offer valuable insights and help detect various CNS disorders. For example:

  • Plasma cells (Figure 1): Associated with antibody production during inflammation.
  • Foam cells (Figure 2): Indicating tissue damage.
  • Erythrophages (Figure 3): Suggesting bleeding in the CSF compartment.
  • Tumor cells (Figure 4): Pointing to malignant infiltration of the meninges.
  • Different pathogens (Figures 5 and 6): Pointing to infection in CNS.

However, simply observing the cells isn’t always enough. That’s where the Coefficient of Energy Balance (KEB) plays a crucial role—it calculates energy production in the affected area by analyzing glucose and lactate molar concentrations. This reveals the activity of immune cells and the severity of inflammation.

The KEB formula:

This formula enhances these insights by estimating the production of adenosine triphosphate (ATP), offering a clearer understanding of metabolic activity and energy demands within the CSF (Figure 7).

The energy pyramid illustrates the energy dynamics in normal and inflamed CSF conditions.

Under normal conditions, CSF metabolism is predominantly aerobic, yielding high ATP production and KEB values above 28.0 (Figure 8).

During inflammation, immune cell activation increases glucose and oxygen consumption, shifting to anaerobic metabolism. This change can result in reduced ATP production and lower KEB values (Figure 9):

  • KEB values above 28.0 indicate aerobic metabolism, which is typical in the absence of inflammation or during mild serous inflammation (Figure 10).
  • KEB values between 28.0 and 15.0 suggest moderate anaerobic metabolism, commonly reflecting the increased energy demands of an activated immune system during a “serous” inflammatory response (Figure 11).

  • KEB values below 10.0 signify strong anaerobic metabolism, typically associated with an intense inflammatory response. This process is characterized by the rapid release of reactive oxygen species by immune cells to combat pathogens, a phenomenon known as the oxidative burst.

The oxidative burst of neutrophils is central to purulent inflammation, a reaction typically triggered by extracellular bacteria in the CNS (Figure 12). In contrast, the oxidative burst of macrophages is crucial for combating intracellular pathogens, fungal infections, or tumor development (Figure 13).

Extending Cytological-Energy Applications

By combining cytological and energy analyses, the KEB method offers a more precise understanding of inflammation across various organ systems (Figures 14–16).

Following successful application in cerebrospinal fluid (CSF) analysis, Dr. Kelbich expanded his collaboration with medical specialists to explore other extravascular body fluids. These included pleural, pericardial, and abdominal effusions, as well as intraocular fluid, peritoneal dialysate, amniotic fluid, synovial fluid, and others. The results were highly promising, demonstrating that cytological-energy analysis has significant potential for broader applications across multiple medical fields.

Towards More Precise Diagnostics

Dr. Kelbich’s approach integrates cytological and metabolic profiling, providing a comprehensive framework for diagnosing inflammatory conditions across various organ systems. By quantifying the type and intensity of immune responses, Cytological-Energy Analysis enables:

  • More precise differentiation between types of local inflammation.
  • Enhanced monitoring of disease progression.
  • More targeted treatment strategies, leading to improved patient outcomes.

This method seamlessly combines scientific knowledge with practical application, offering deeper insights into localized bodily processes. It represents a promising tool to advance the diagnosis and treatment of a wide range of conditions, ultimately benefiting patients worldwide.
