Toxoplasma myositis
ICD-10 B58.82 is a billable code used to indicate a diagnosis of toxoplasma myositis.
Toxoplasma myositis is an inflammatory condition of the muscles caused by the protozoan parasite Toxoplasma gondii. This infection is particularly significant in immunocompromised individuals, such as those with HIV/AIDS or those undergoing immunosuppressive therapy. The parasite is typically transmitted through ingestion of oocysts found in contaminated food or water, or through contact with infected cat feces. In healthy individuals, Toxoplasma gondii often remains asymptomatic or causes mild flu-like symptoms. However, in immunocompromised patients, it can lead to severe complications, including myositis, which presents with muscle pain, weakness, and swelling. Diagnosis is primarily through serological testing for Toxoplasma antibodies, and muscle biopsy may be performed to confirm the presence of the parasite. Treatment typically involves the use of pyrimethamine and sulfadiazine, along with leucovorin to mitigate the side effects of pyrimethamine. Early diagnosis and treatment are crucial to prevent further complications, including systemic involvement and potential organ failure.
Detailed history of exposure, serological test results, and clinical symptoms.
Patients presenting with muscle pain and weakness, particularly in immunocompromised individuals.
Ensure thorough documentation of the patient's immune status and any concurrent infections.
Comprehensive assessment of muscle involvement and exclusion of other autoimmune myopathies.
Patients with unexplained myositis symptoms who may have underlying infections.
Differentiating between infectious and autoimmune causes of myositis.
Used to confirm diagnosis in patients suspected of Toxoplasma infection.
Document the reason for testing and the patient's clinical presentation.
Infectious disease specialists should ensure comprehensive testing for other co-infections.
Common symptoms include muscle pain, weakness, swelling, and in severe cases, systemic involvement leading to complications.
Diagnosis is typically made through serological testing for Toxoplasma antibodies and may include muscle biopsy for confirmation.
Treatment usually involves antiparasitic medications such as pyrimethamine and sulfadiazine, along with supportive care.
