[Sexual transmission of strongyloidiasis in men who have sex with men (MSM) in Paris].

INTRODUCTION

The sexual transmission of intestinal parasites has been reported for a long time, even before the HIV pandemic. It mainly involves protozoa. More rarely, helminths are involved: Strongyloides stercoralis, Enterobius vermicularis. This type of transmission is almost exclusively observed in men who have sex with men (MSM) through direct oral-genital-anal sexual contact.

OBSERVATIONS: We present four cases of sexually transmitted strongyloidiasis in MSM.

DISCUSSION: Several associated factors were found: HIV infection, recurrent episodes of other sexually transmitted infections, or risk factors: sexual relations with men from regions endemic for S. stercoralis, rimming, chemsex, scatological practices. In MSM, strongyloidiasis must be considered and investigated in the presence of eosinophilia, which may be fluctuating, with or without digestive and/or cutaneous signs, even in the absence of a stay in a tropical zone.

CONCLUSION

These MSM patients must be thoroughly questioned, with details of their sexual behavior leading to appropriate prophylactic advice, such as unprotected oral-genital-anal intercourse.
