Hemoglobin level as a risk factor for lower respiratory tract infections

Area of Science:

• Pediatrics
• Infectious Diseases
• Hematology

Background:

• Lower Respiratory Tract Infections (LRTI) are a major cause of childhood morbidity.
• Anemia is a common condition in children, with various underlying etiologies.
• The relationship between hemoglobin levels and LRTI risk requires further investigation.

Purpose of the Study:

• To evaluate the role of hemoglobin levels as a risk factor for LRTI in children.
• To compare the prevalence of anemia in children with and without LRTI.

Main Methods:

• A prospective study included 100 children diagnosed with LRTI and 100 age- and sex-matched controls without respiratory illness.
• Diagnostic tests included complete blood count (CBC), C-reactive protein (CRP), Mantoux test, and chest X-ray.
• Anemic children underwent peripheral smear, serum ferritin, and serum iron-binding capacity tests.

Main Results:

• Radiological pneumonia was present in 63% of LRTI cases.
• Anemia was significantly more prevalent in the LRTI group (74%) compared to controls (33%).
• Low hemoglobin levels were identified as a significant risk factor for LRTI (p=0.000).

Conclusions:

• Anemic children were 5.75 times more susceptible to LRTI than the control group.
• Preventing anemia, regardless of its cause, is crucial for reducing LRTI incidence.
• Addressing anemia can significantly impact pediatric respiratory health.
