Predisposing Factors to Infections in Thalassemia Syndrome Patients

Area of Science:

• Hematology
• Infectious Diseases
• Medical Research

Background:

• Thalassemia, an inherited blood disorder causing chronic anemia, increases infection susceptibility.
• Transfusion-dependent patients face risks from anemia, iron overload, and splenectomy.
• Understanding infection factors is crucial for improving thalassemia patient management.

Purpose of the Study:

• To explore factors contributing to infections in thalassemia patients.
• To identify key risk factors for infection in this population.
• To inform strategies for reducing infection incidence and improving patient outcomes.

Main Methods:

• Retrospective analysis of 303 thalassemia patients (2007-2022).
• Data collection included demographics, transfusion status, splenectomy, ferritin, vaccination, and culture results.
• Logistic regression identified infection risk factors (p < 0.05).

Main Results:

• 72 patients (23.8%) had culture-positive infections; Escherichia coli was most common.
• Infected patients had higher ferritin levels and less chelation therapy (OR 0.18, p < 0.001).
• Higher serum albumin (OR 0.92, p < 0.001) and chelation therapy correlated with lower infection odds; mortality was higher with infections (22% vs 3%).

Conclusions:

• A strong association exists between iron overload, chelation therapy, and infection risk in thalassemia.
• Effective chelation and ferritin monitoring are critical for reducing infections.
• Further research is needed to confirm findings and guide future thalassemia management.
