Tapeworm (Taenia solium) Treatment – Taeniasis, Cysticercosis, and Neurocysticercosis (NCC)

Precaution must always be taken before and during the treatment of neurocysticercosis (NCC) to prevent adverse events, especially in patients with intracranial hypertension secondary to NCC. If any lesions could be present in the nervous system or eyes, ocular cysticercosis, intraventricular NCC, massive/encephalitic NCC, and lesions in the brainstem and other high-risk areas must be ruled out before pharmacotherapy is initiated for a tapeworm infection.¹

There is never an urgent need for pharmacotherapy for patients with NCC. Moreover, the NCC treatment plan must always be individualized after the number and locations of lesions are determined. Ideally, patients with NCC will be managed by an experienced and multidisciplinary team of qualified healthcare professionals, including specialists in infectious disease, neuroradiology, neurology, pediatrics, and neurosurgery.¹

The diagnosis of NCC can be challenging, even with imaging. For example, the differential for multiple ring-enhancing lesions of the brain is broad and includes bacterial abscess, tuberculosis, syphilis, toxoplasmosis, echinococcosis, multiple sclerosis (MS), coccidioidomycosis, cryptococcosis, aspergillosis, neoplastic metastasis, CNS lymphoma, and sarcoidosis.²

Symptoms of NCC, including seizures and headaches, should be managed until it is safe to consider surgery and or antiparasitic medications. Treatment of NCC with antiparasitic medications must always be performed under medical supervision for at least one week. The medications must also be administered with concomitant steroid therapy to prevent adverse events, and preceded by appropriate symptomatic treatment.¹

Taenia solium Treatment Protocols

Once NCC is ruled out or managed appropriately concomitantly, treatment for taeniasis or cysticercosis can be prescribed. Pharmaceutical treatment options are noted in the document Taenia solium (Tapeworm) Treatment Protocols, which is posted on the Provider Tools page in the Provider Portal.

One animal study suggests that progesterone could be protective and open the door for the treatment of gastrointestinal helminth infections using the immunoendocrinological network.^3,4 Therefore, also ensure that saliva (free) steroid hormone levels, including progesterone, are optimal.

The most important goal when treating taeniasis is the prevention of NCC and cysticercosis. Therefore, eradication must be confirmed with extensive follow-up testing after treatment. According to the guidelines recommended by the international and interdisciplinary expert group known as COHEMI, microscopic and macroscopic examination of stool samples repeated on three different days at one and three months after treatment should be ordered. If a test result is positive, the treatment protocol and additional follow-up testing must be repeated until all follow-up testing is negative.¹

Testing other household members, discussing and implementing all food safety guidelines, initiating preventive strategies, and ruling out a chronic, ongoing exposure to a source of Taenia solium could also be indicated if the first round of taeniasis treatment fails.

Infection with Taenia solium is a significant danger to human health and livestock production.⁵ Fortunately, readily available and affordable screening and diagnostic testing from DiagnosTechs will help facilitate the treatment of current infections and the prevention of future infections.
