PFAPA syndrome

PFAPA (Periodic Fever, Aphthous Stomatitis, Pharyngitis, and Adenitis) syndrome is a periodic fever syndrome that typically manifests between ages 2 to 6 years old [3]. It causes recurring episodes of fever that last 3 to 6 days, accompanied by mouth sores (aphthous stomatitis), sore throat (pharyngitis), and swollen lymph nodes (adenitis) [7][8].

The symptoms of PFAPA syndrome are characterized by:

• Repeated episodes of fever
• Mouth sores (aphthous stomatitis)
• Sore throat (pharyngitis)
• Swollen lymph nodes (adenitis)

These symptoms occur due to an abnormal immune system response, making PFAPA an autoinflammatory disease [1][2]. It is not triggered by infection and is not contagious. In about 15% of patients, PFAPA persists into adulthood [2].

PFAPA syndrome is the most common cause of periodic fever syndromes in children, accounting for approximately 50-70% of cases [5][6]. The exact cause of PFAPA remains unknown.

PFAPA syndrome, also known as Periodic Fever, Aphthous Stomatitis, Pharyngitis, and Adenitis, is a rare autoinflammatory disorder that affects children. The signs and symptoms of PFAPA syndrome can vary from child to child, but they often include:

• Recurring fevers: Children with PFAPA syndrome experience repeated episodes of fever, which can last for several days.
• Mouth sores (stomatitis): PFAPA syndrome is characterized by the presence of mouth ulcers or sores, which can be painful and uncomfortable for children.
• Sore throat (pharyngitis): Children with PFAPA syndrome often experience a sore or red throat, which can be accompanied by white patches on the tonsils.
• Swollen lymph nodes: The lymph nodes in the neck may become swollen and tender during episodes of fever.
• Fatigue and chills: Children with PFAPA syndrome may feel tired and experience chills, especially during periods of fever.
• Abdominal pain and headache: Some children may also experience abdominal pain and headaches, although these symptoms are not as common.

According to [3], PFAPA syndrome causes fatigue, chills, and occasionally abdominal pain and headache, as well as fever, sore throat, mouth ulcers, and swollen lymph nodes. This information is consistent with the description provided in [1] and [4].

It's worth noting that PFAPA syndrome typically affects children between the ages of 2 and 5 years old, and the symptoms can vary from episode to episode. If you suspect your child may have PFAPA syndrome, it's essential to consult a healthcare professional for proper diagnosis and treatment.

Diagnostic Tests for PFAPA Syndrome

PFAPA (Periodic Fever, Aphthous Stomatitis, Pharyngitis, Adenitis) syndrome is a rare condition that affects children and young adults. While there are no specific diagnostic tests for PFAPA syndrome, various laboratory and clinical evaluations can help establish the diagnosis.

Laboratory Tests

• Blood tests, such as white blood counts, may be performed to look for signs of infection [1].
• Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are common markers of inflammation that rise during fevers [3].
• Other causes of fever and inflammation can be ruled out through laboratory tests.

Clinical Evaluation

• The diagnosis of PFAPA syndrome is primarily based on clinical criteria, including:
  • Recurring episodes of fever
  • Aphthous stomatitis (mouth sores)
  • Pharyngitis (sore throat)
  • Adenitis (swollen lymph nodes) [8]
• A physical exam and medical history can also help establish the diagnosis.

Genetic Testing

• Genetic testing may be recommended for patients with a high-risk Gaslini score to rule out other conditions [4].

Summary

In summary, while there are no specific diagnostic tests for PFAPA syndrome, various laboratory and clinical evaluations can help establish the diagnosis. A combination of blood tests, clinical evaluation, and genetic testing (if necessary) can aid in diagnosing this rare condition.

Treatment Options for PFAPA Syndrome

PFAPA (Periodic Fever, Aphthous Stomatitis, Pharyngitis, and Adenitis) syndrome is a rare condition characterized by recurring episodes of fever, mouth sores, sore throat, and swollen lymph nodes. While there is no specific treatment for PFAPA, various medications can help manage its symptoms.

Medications Used to Treat PFAPA

• Corticosteroids: These are often the first line of treatment for PFAPA, as they can help reduce inflammation and fever episodes [1][2].
• Colchicine: This medication has been shown to be effective in reducing the frequency and severity of fever episodes in some patients with PFAPA [3][4].
• Cimetidine: Another medication that may be prescribed to help manage symptoms, particularly mouth sores and sore throat [5].
• Nonsteroidal anti-inflammatory drugs (NSAIDs): These can be used to reduce fever and alleviate pain, although their effectiveness in treating PFAPA is limited [6].

Surgical Treatment

In some cases, surgical removal of the tonsils (tonsillectomy) may be considered as a treatment option for PFAPA. This procedure has been shown to cure the condition in more than 80% of children who undergo it [7].

It's essential to note that each patient with PFAPA is unique, and the most effective treatment plan will depend on individual circumstances.

PFAPA (Periodic Fever, Aphthous Stomatitis, Pharyngitis, and Adenitis) syndrome is a complex condition that requires a comprehensive differential diagnosis to rule out other potential causes of the symptoms.

Infectious Causes

• Infectious pharyngitis: This is often the first consideration in the differential diagnosis of PFAPA syndrome. However, the absence of typical upper respiratory tract infection symptoms (such as cough and runny nose) can help differentiate it from infectious pharyngitis [1].
• Cyclic neutropenia: This condition also presents with recurrent episodes of fever, but it is characterized by a significant decrease in white blood cell count [1].

Autoinflammatory Disorders

• PFAPA syndrome itself is an autoinflammatory disease, meaning that the immune system is overactive and causes inflammation. However, its exact cause remains unknown [2].
• Other autoinflammatory disorders, such as mevalonate kinase deficiency and familial Mediterranean fever, may present with similar symptoms to PFAPA syndrome [3].

Other Conditions

• Hereditary fever syndromes: Although the genetic cause of PFAPA syndrome is not yet determined, it tends to be grouped with hereditary fever syndromes due to its recurrent nature [4].
• Other conditions that may mimic PFAPA syndrome include periodic fever syndromes and other autoinflammatory disorders.

Key Points

• Infectious pharyngitis can often be ruled out by the absence of typical upper respiratory tract infection symptoms.
• Cyclic neutropenia is a consideration in cases with significant decreases in white blood cell count.
• Autoinflammatory disorders, such as mevalonate kinase deficiency and familial Mediterranean fever, may present with similar symptoms to PFAPA syndrome.
• Hereditary fever syndromes are often grouped with PFAPA syndrome due to its recurrent nature.
