Sporotrichosis Diagnosis and Testing
Sporotrichosis is typically diagnosed when your doctor obtains a swab or a biopsy of the infected site and sends the sample to a laboratory for a fungal culture. Serological tests are not always useful in the diagnosis of sporotrichosis due to limitations in sensitivity and specificity.
Treatment and Outcomes for Sporotrichosis
Most cases of sporotrichosis only involve the skin and/or subcutaneous tissues and are non-life-threatening, but the infection requires treatment with prescription antifungal medication for several months. The most common treatment for this type of sporotrichosis is oral itraconazole for 3 to 6 months. Itraconazole may also be used to treat bone and joint infections, but treatment should continue for at least 12 months.
For patients with severe disease, and/ or an infection that has spread throughout the body, a lipid formulation of amphotericin B should be used. Itraconazole can be used for step-down therapy once the patient has stabilized. Supersaturated potassium iodide (SSKI) is another treatment option for cutaneous or lymphocutaneous disease. SSKI and azole drugs like itraconazole should not be used during pregnancy. Treatment recommendations may differ for children.
How Can I Prevent Sporotrichosis?
There is no vaccine to prevent sporotrichosis. You can reduce your risk of sporotrichosis by wearing protective clothing such as gloves and long sleeves when handling wires, rose bushes, bales of hay, pine seedlings, or other materials that may cause minor cuts or punctures in the skin. It is also advisable to avoid skin contact with sphagnum moss.
