[Nephrological aspects of complement-mediated thrombotic microangiopathy]

Area of Science:

• Nephrology
• Hematology
• Internal Medicine

Background:

• Complement-mediated thrombotic microangiopathy (C-TMA) is a severe condition.
• Delayed diagnosis of C-TMA is associated with significant morbidity and organ damage.

Purpose of the Study:

• To analyze complement-mediated thrombotic microangiopathy (C-TMA) cases in a hospital nephrology department.
• To evaluate the clinical course, treatment, and short-term outcomes of C-TMA.

Main Methods:

• Prospective study of 10 newly diagnosed C-TMA patients over one year.
• Collected demographic data, clinical severity, organ involvement, and treatment outcomes (plasma therapy, eculizumab).
• Assessed hematological remission and need for renal replacement therapy (RRT).

Main Results:

• Median diagnostic delay was 5 months; incidence was 6.4/1000 inpatients.
• All patients had renal dysfunction, 80% required RRT.
• No fatal outcomes; all achieved hematological remission. 30% recovered kidney function and stopped dialysis.

Conclusions:

• C-TMA is severe, causing multi-organ dysfunction and high risk of end-stage renal failure if diagnosed late.
• Early detection and treatment are key to improving renal prognosis in C-TMA.
• Prompt intervention can lead to recovery of kidney function and cessation of dialysis.
