There have been few studies on human trichostrongyliasis in Southeast Asia, information on its clinical manifestations is also sparse. Trichostrongyliasis occurs predominantly in areas where poor hygiene is common especially where human/animal feces are used as a fertilizer, thereby contaminating vegetables and stream water. The intimate coexistence of domestic animals and humans explains the prevalence of Trichostrongylus infection in such areas. The goal of the current study was to determine the prevalence of trichostrongyliasis among villagers in Thakamrien village, Sonkon district, Savannakhet province, Laos, and to investigate potential relationships between clinical features, laboratory data, and severity of infection. Of 272 villagers examined, 160 (58.8%) were determined positive for helminthic infections by fecal examination, and 59 (36.9%) of these were infected with Trichostrongylus. Only 58 cases were in the inclusion criteria of the study and then underwent further assessment, including a questionnaire on personal behaviors, physical examination, and laboratory tests. Villagers in the trichostrongyliasis group were more likely than the control group to have consumed fresh vegetables, not washed their hands before meals or after using the toilet, and to have had close contact with herbivorous animals (goats and cows). Similarly, villagers in the trichostrongyliasis group were more likely than the control group to have a history of loose feces, rash, or abdominal pain; however, no obvious clinical symptoms were observed during physical examination of the trichostrongyliasis patients. The degree of infection was determined by both fecal egg counts and quantification of adult worms after deworming. Laboratory data were evaluated for any relationship with severity of infection. No significant differences were found in laboratory values between the trichostrongyliasis and control groups, with most values being within normal limits; however, both groups had high eosinophil counts. This study demonstrated that the useful clinical characteristics of trichostrongyliasis patients include history of loose feces, rashes, and abdominal pain, as well as in personal behaviors, such as the regular consumption of fresh vegetables, lack of hand washing, and close contact with cattle.

Trichostrongylus is a common nematode found to infect livestock throughout the tropics and can cause accidental zoonosis in humans. In the Lao PDR and Thailand, cases of human trichostrongyliasis have been reported sporadically but clinical data are limited. We retrospectively reviewed 41 cases of trichostrongyliasis who presented to Srinagarind Hospital, Thailand from 2005 to 2012. The diagnosis of trichostrongyliasis was made by finding their eggs in the stool of patients. Of the 41 cases reviewed, 30 were Thais and 11 from the Lao PDR; their age range was 26-86 years. Fifty-eight point five percent of the cases were male, 56.1% had a primary school or a lower education level, 56.1% were farmers or laborers, 63.4% lived in a rural area and 95.1% had underlying disease. Twenty-one patients were co-infected with Opisthorchis viverrini (14/21; 66.7%) and Strongyloides stercoralis (10/21; 47.6%) while the remaining (n = 20) had a single infection with Trichostrongylus only. All the trichostrongyliasis only patients who had underlying disease not related to the gastrointestinal (GI) tract had normal bowel habits and normal grossly appearing stool. GI symptoms, such as abdominal pain, flatulence, bloating, nausea, vomiting, anorexia, diarrhea and constipation, were not found in these patients suggesting they had a light infection. This study is the first report of the clinical features of a trichostrongyliasis case series from tertiary care hospital in Thailand.
