Sounds like you are talking about a case of the hyperinfective syndrome due
to Strongyloides stercoralis. Diagnosis is often missed since presentations
can vary quite markedly. If your mother still has larval migration tracks on
the skin, antinematode therapy has not yet killed them. Typically with
hyperinfection the patient has thousands of adult S. stercoralis in the
mucosa in many parts of the gastrointestinal tract, and thousands of
autoinfective larvae migrating in the gut wall and other organs of the body.

What sort of information are you after? Hyperinfection is a life threatening
situation as you know. Many patients in this state die from bacterial
infection and multisystem failure. Management consists of focusing on
controlling the septic aspects if they exist, manageing organ failure,
killing the adult parasites in the gut, and killing the migrating
To kill the adult Strongyloides the best drugs are ivermectin and
albendazole. In hyperinfection, ivermectin may be the drug of choice. No
double blind therapeutic trials appear to have been published on treatment
but one interesting case series was reported in Clin Infect Dis (1993)
"Efficacy of ivermectin in the treatment of strongyloidiasis complicating
AIDS." by Torres JR, Isturiz R, Murillo J, Guzman M, Contreras R. They found
that the best treatment was 200 micrograms/kg on a multidose schedule on
days 1, 2, 15, and 16. All seven patients who received multiple doses showed
sustained clinical and parasitological cure; whereas one of two patients who
received single dose therapy relapsed promptly and fatally. However,
treatment failures have been reported even after multiple doses of
ivermectin in some cases of chronic uncomplicated strongyloidiasis.
Killing autoinfective larvae of S. stercoralis is more difficult, and both
drugs may not be very efficient. If a patient does survive a severe
hyperinfective crisis, monitoring for Strongyloides after recovery has to be
prolonged and enthusiastic as the parasite is quite difficult to eradicate.
Repeat courses of albendazole or ivermectin will be required.
Hope this is of some assistance.
