Abstract

Insights

Mumps virus infection can trigger secondary autoimmune hemolytic anemia (AIHA) in children. Prompt treatment improved the patient's condition, highlighting the need to investigate underlying causes for pediatric AIHA.

Area of Science:

  • Pediatric Hematology
  • Viral Infections
  • Immunology

Background:

  • Autoimmune hemolytic anemia (AIHA) is a condition where the immune system attacks red blood cells.
  • While often idiopathic, AIHA can be secondary to various underlying conditions.
  • Investigating potential triggers is crucial, especially in pediatric cases.

Observation:

  • A 12-year-old boy presented with hemolytic anemia and altered consciousness.
  • Initial diagnosis was idiopathic hemolytic anemia, responsive to corticosteroids, immunoglobulins, and transfusions.
  • Later, symptoms of epidemic parotitis (mumps) emerged, confirmed by elevated serum and urine amylase levels.

Findings:

  • The patient's autoimmune hemolytic anemia was determined to be secondary to mumps virus infection.
  • Successful treatment involved corticosteroids, immunoglobulins, and supportive care.
  • The parotitis diagnosis was established through clinical signs and laboratory markers.

Implications:

  • This case underscores that AIHA in children may manifest as a symptom of an underlying viral illness.
  • Early identification and management of the trigger, like mumps virus, are essential for effective treatment.
  • Further research into the link between viral infections and secondary AIHA in pediatric populations is warranted.

Poliomyelitis01:17

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...

Encephalitis ll: Pathophysiology

Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
Encephalitis l: Introduction01:19

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
Viral Meningitis01:18

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...
Chickenpox01:20

Chickenpox

Chickenpox is an acute, highly contagious disease caused by the varicella-zoster virus (VZV), a double-stranded DNA virus belonging to the Herpesviridae family. Its transmission occurs primarily through the inhalation of respiratory droplets or direct contact with vesicular fluid from skin lesions. The incubation period typically ranges from 10 to 21 days, during which the virus replicates and disseminates through sequential phases within the host. Although generally self-limiting in children,...
Viral Hepatitis I: Introduction01:28

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
