[Management of thrombotic microangiopathy]

Area of Science:

• Hematology
• Internal Medicine
• Emergency Medicine

Background:

• Thrombotic microangiopathy (TMA) is a critical condition demanding immediate medical attention.
• Understanding the underlying pathophysiology is essential for timely and effective treatment, aiming to minimize patient morbidity and mortality.
• Thrombotic thrombocytopenic purpura (TTP) is a significant differential diagnosis within the spectrum of TMA.

Purpose of the Study:

• To highlight the importance of systematically considering TTP in cases of TMA.
• To introduce and discuss the utility of diagnostic scoring systems (French and PLASMIC scores) in the initial assessment of TMA.
• To emphasize the need for early treatment initiation in suspected TTP cases, even before definitive diagnostic confirmation.

Main Methods:

• Review of clinical cases presenting with TMA.
• Application of French and PLASMIC scoring systems for TTP probability assessment.
• Discussion of management strategies based on diagnostic scores and clinical suspicion.

Main Results:

• The presented cases illustrate diverse TMA presentations and their management pathways.
• Diagnostic scores can aid in stratifying TTP risk upon patient admission.
• Early therapeutic intervention in high-probability TTP cases is demonstrated as a viable strategy.

Conclusions:

• Prompt recognition and etiological diagnosis of TMA are paramount for effective patient outcomes.
• The French and PLASMIC scores serve as valuable tools for the initial evaluation of TMA, particularly for identifying TTP.
• Initiating treatment for TTP based on high clinical probability, supported by scoring systems, can expedite care and improve prognosis.
