Summary
Severe congenital neutropenia, a primary immunodeficiency, causes severe infections due to low neutrophil counts. Early diagnosis and treatment with granulocyte colony-stimulating factor improve patient outcomes.
Area of Science:
- Pediatrics
- Immunology
- Hematology
Background:
- Severe congenital neutropenia (SCN) is a primary immunodeficiency characterized by impaired neutrophil maturation in bone marrow.
- This leads to profound neutropenia and increased susceptibility to severe, recurrent bacterial and fungal infections.
Purpose of the Study:
- To report a case of SCN in an infant presenting with severe infections shortly after birth.
- To highlight the importance of early diagnosis and treatment for SCN.
Main Methods:
- Clinical case presentation of an infant with SCN.
- Diagnostic confirmation through bone marrow examination revealing myeloid maturation arrest.
- Treatment initiated with granulocyte colony-stimulating factor (G-CSF).
Main Results:
- The infant presented at 4 days of life with perianal abscess, sepsis, liver abscess, gingivitis, and oral ulcers.
- Infections were caused by Pseudomonas aeruginosa, Staphylococcus hominis, and Klebsiella sp.
- Bone marrow examination confirmed SCN, and G-CSF treatment was initiated.
Conclusions:
- SCN should be considered in neonates presenting with neutropenia and infections within the first month of life.
- Prompt diagnosis and initiation of G-CSF treatment are crucial for improving survival and quality of life in affected infants.

Immunodeficiency Diseases
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.

Inborn Errors of Metabolism
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...
Disorders of Leukocytes
Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...

Acute Pyelonephritis I: Introduction
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such as Proteus,...
Cytomegalovirus Disease
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
Disorders of Erythrocytes
Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
