DIAGNOSIS: Strongyloidiasis

The nematode Strongyloides stercoralis is known to be a common source of infection in Third World countries, is now recognized to be common in certain parts of the United States, and may be endemic in institutions.The infection may remain dormant and subclinical for many years. It is especially important to diagnose and treat this infection prior to institution of immunosuppressive therapy. Otherwise, an overwhelming fatal infection may follow. Gastrointestinal symptoms, if present, are usually mild, with only minimal change in villous architecture. Occasionally, heavy infestations may be T-associate with a severe lesion of villous architecture and related severe malabsorption. The primary mode of diagnosis is stool examination, although serologic testing is an adjunct. Sometimes the diagnosis is made on the basis of small bowel biopsy or biopsy from other parts of the gastrointestinal tract. The possibility of endemic strongyloidiasis should always be considered in patients who have unexplained high eosinophilic count.
