Strongyloidiasis is an intestinal parasitic disease caused by Strongyloides
stercoralis, Basically, detecting larvae of S. stercoralis in feces makes
definitive diagnosis. The ordinary agar plate culture method developed at o
ur department is much simpler to handle and much more sensitive than the co
nventional filter paper culture method. It is considered to be the most use
ful method in the diagnosis of strongyloidiasis and in evaluation of the er
adicating effect. Among chemotherapeutic agents, thiabendazole representing
the benzimidazole compounds is most effective. However, it has a problem i
n safety, since its adverse effects and liver dysfunction occur with a high
incidence, and it can be severe. Regarding the effects of mebendazole, alb
endazole and ivermectin, a study was conducted which included many patients
. A high incidence of liver dysfunction was observed with mebendazole, and
eradicating effect was not sufficient with albendazole, Ivermectin is diffe
rent from benzimidazole compounds in a pharmacokinetic profile, However, iv
ermectin showed a strong anthelmintic effect with the least toxicity. We th
erefore consider ivermectin is the most useful drug for the treatment of st
rongyloidiasis.
