Paroxysmal nocturnal hemoglobinuria associated with infectious mononucleosis
Blood
|August 1, 1979
Summary
Infectious mononucleosis may trigger paroxysmal nocturnal hemoglobinuria (PNH), a rare blood disorder. This case highlights a potential link between viral infections and the onset of PNH in adolescents.
Area of Science:
- Hematology
- Infectious Diseases
- Genetics
Background:
- Presents a case study of a 16-year-old female with no prior health issues.
- Focuses on the development of blood disorders following infectious mononucleosis.
Observation:
- The patient exhibited pancytopenia, low reticulocyte count, and cellular bone marrow.
- Clinical and laboratory signs of infectious mononucleosis were present.
- Pancytopenia and hemolytic anemia persisted after the resolution of infectious mononucleosis symptoms.
Findings:
- Sucrose hemolysis and acid hemolysis tests confirmed paroxysmal nocturnal hemoglobinuria (PNH).
- After 18 months, platelet counts normalized, but leukopenia and hemolytic anemia persisted.
- The patient's condition suggests a potential causal link between infectious mononucleosis and PNH development.
Implications:
- This case suggests infectious mononucleosis as a potential trigger for paroxysmal nocturnal hemoglobinuria.
- Highlights the importance of considering PNH in patients presenting with persistent cytopenias post-viral infections.
- Underscores the need for further research into the relationship between viral illnesses and the pathogenesis of PNH.

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...

Bacterial Meningitis
Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
Atypical Pneumonia
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
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...
Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
