What is Heerfordt Syndrome?
Heerfordt syndrome – also known as uveoparotid fever or Febris uveoparotidea – is a rare but distinctive presentation of sarcoidosis, a systemic inflammatory disease in which clusters of inflammatory cells (granulomas) form in various organs. It was first described in 1909 by Danish ophthalmologist Christian Frederick Heerfordt. The condition most commonly affects young adults and appears to occur more frequently in women.
Causes
Heerfordt syndrome is a specific manifestation of sarcoidosis. The exact cause of sarcoidosis remains incompletely understood. Current evidence suggests that an exaggerated immune response to certain triggers – possibly bacteria, viruses, or environmental antigens – leads to the formation of non-caseating granulomas in genetically susceptible individuals. These granulomas can deposit in the parotid glands, eyes, nervous system, and other organs.
Symptoms
Classic Heerfordt syndrome is defined by four cardinal features, often referred to as the Heerfordt tetrad:
- Parotid gland enlargement: Painless or mildly tender swelling of the parotid (salivary) glands, typically bilateral.
- Uveitis: Inflammation of the middle layer of the eye (the uvea), which may present as redness, photosensitivity, and eye pain, and can lead to vision impairment if untreated.
- Facial nerve palsy: Weakness or paralysis of the facial nerve (cranial nerve VII), resulting in one-sided or bilateral drooping of the facial muscles.
- Fever: Persistent low-grade to high fever reflecting the systemic inflammatory process.
Not all four features need to be present simultaneously. Additional manifestations may include fatigue, general malaise, enlargement of other salivary glands, and neurological deficits in the context of neurosarcoidosis.
Diagnosis
The diagnosis of Heerfordt syndrome is established through a combination of clinical evaluation, laboratory testing, and imaging:
- Clinical assessment: Identification of the characteristic features including parotid swelling, uveitis, facial palsy, and fever.
- Laboratory tests: Elevated inflammatory markers (CRP, ESR), raised serum angiotensin-converting enzyme (ACE) levels as a marker for sarcoidosis, and occasionally hypercalcemia.
- Imaging: Chest X-ray or CT scan to detect bilateral hilar lymphadenopathy, a hallmark of pulmonary sarcoidosis. Brain MRI if neurological involvement is suspected.
- Biopsy: Tissue sampling from the parotid gland or another affected organ to histologically confirm non-caseating granulomas – considered the gold standard for diagnosis.
- Ophthalmological examination: Slit-lamp examination to assess the extent of uveitis.
Treatment
Treatment of Heerfordt syndrome is guided by the severity of symptoms and extent of organ involvement. There is no curative therapy for sarcoidosis; management is therefore aimed at controlling inflammation and preventing organ damage.
Corticosteroids
Corticosteroids (e.g., prednisone or prednisolone) are the mainstay of treatment. They suppress the overactive immune response and can significantly reduce parotid swelling, uveitis, and facial nerve palsy. Systemic corticosteroids are typically administered orally and continued for several months depending on treatment response.
Eye Drops
For uveitis, topical corticosteroid eye drops and mydriatic agents (pupil-dilating drops) are used in addition to systemic therapy to reduce intraocular inflammation and prevent posterior synechiae (adhesions of the iris).
Immunosuppressive Agents
In severe or corticosteroid-refractory cases, immunosuppressive medications such as methotrexate, azathioprine, or hydroxychloroquine may be employed as steroid-sparing agents.
Prognosis
Heerfordt syndrome generally carries a favorable prognosis. With appropriate treatment, symptoms often resolve completely. Facial nerve palsy is reversible in the majority of cases. Regular ophthalmological follow-up is important to detect potential complications of uveitis, such as cataracts or secondary glaucoma, at an early stage.
