PFAPA syndrome (Periodic Fever, Aphthous Stomatitis, Pharyngitis, and Adenitis) is the most common non-genetic periodic fever syndrome. It’s characterized by recurrent episodes of fever, mouth sores, sore throat, and swollen lymph nodes.
Overview
PFAPA syndrome typically begins in early childhood, usually before the age of 5. The condition is named for its most common symptoms:
- Periodic Fever: Individuals with PFAPA syndrome experience recurrent episodes of high fever that last for 3-6 days.
- Aphthous Stomatitis: This refers to mouth sores, similar to canker sores, that often accompany the fever.
- Pharyngitis: This is inflammation of the throat, causing a sore throat.
- Adenitis: This refers to inflammation of the lymph nodes, often causing them to become swollen and tender.
One of the defining characteristics of PFAPA syndrome is its periodicity. Individuals with PFAPA syndrome experience episodes, or flares, of symptoms that occur with a predictable frequency, typically every 3 to 8 weeks. These flares often start suddenly and can last for several days, usually around 3 to 6 days.
Interestingly, the timing of these flares can be so regular that families often can predict almost to the day when the next flare will occur. This periodicity is unique to PFAPA syndrome and is one of the key factors that help doctors make a diagnosis.
Between flares, individuals with PFAPA syndrome are completely healthy with no symptoms. However, the regular return of flares can significantly impact a child’s life and family routine. Understanding and anticipating this periodicity can help manage the condition and plan for the onset of symptoms.
Symptoms
The symptoms of PFAPA syndrome come in episodes, or flares, that occur every few weeks. Each flare is usually the same in terms of the symptoms it causes and its duration. In addition to the symptoms listed above, individuals with PFAPA syndrome may also experience:
- Headache
- Abdominal pain
- Joint pain
- General feeling of being unwell
Natural Course of PFAPA Syndrome
A reassuring aspect of PFAPA syndrome is its self-limiting nature. While the recurrent episodes of fever and other symptoms can be distressing, it’s important to know that in most cases, PFAPA syndrome does not continue into adulthood.
The frequency of episodes tends to decrease over time. By late childhood or early adolescence, most individuals with PFAPA syndrome find that their episodes become less frequent and eventually stop altogether. This spontaneous resolution is a unique feature of PFAPA syndrome, and while the syndrome can cause significant disruption during the years it is active, it does not typically result in any long-term health problems.
However, during the active phase of the disease, it’s important to manage the symptoms effectively to ensure the child’s comfort and well-being. Regular follow-ups with the healthcare provider are recommended to monitor the course of the disease and adjust treatment strategies as needed.
Diagnosis
PFAPA syndrome is diagnosed based on the characteristic pattern of symptoms. There’s no specific test for PFAPA syndrome, but doctors may perform tests to rule out other conditions with similar symptoms.
Treatment
Treatment for PFAPA syndrome is aimed at managing symptoms and preventing flares. This can include:
- Fever-reducing medications: These can help manage the high fever that comes with each flare.
- Corticosteroids: These medications can often stop a flare in its tracks if taken at the first sign of symptoms.
- Tonsillectomy: In some cases, removing the tonsils can reduce the frequency and severity of flares.
Living with PFAPA Syndrome
Living with PFAPA syndrome can be challenging due to the recurrent nature of the symptoms. However, most children with PFAPA syndrome outgrow the condition by their teenage years. In the meantime, treatment can help manage symptoms and improve quality of life.
