“…Such colonizations are generally asymptomatic and discovered by accident while screening for other conditions [28,36,37]. Although much rarer than adverse reactions to roundworms, adverse reactions associated with uncontrolled HDC colonization have been reported [38,39,40,41]. The rarity of case reports associated with HDC colonization, despite the fact that the organisms are very common in nature [42], probably reflects the fact that HDCs fail to colonize (live to adulthood) in the vast majority of individuals who encounter the organism.…”

Background. Biome depletion, or loss of biodiversity from the ecosystem of the human body, is a major "evolutionary mismatch" underlying a variety of inflammatory diseases in Western populations. Enhancing biodiversity via exposure to helminths has effectively treated immune diseases in a variety of experimental animal models and in a few published studies involving human subjects. Purpose. This study probes another untapped resource for helminthic therapy: the methods and outcomes reported by individuals currently self-treating with helminths. Procedures. Helminth providers were interviewed, surveys were collected from self-treaters, and publically available information was compiled. Results. More than 250 anecdotal experiences of self-treatment were assessed, and the total number of individuals worldwide currently self-treating was estimated at between 6,000 and 7,000. A wide range of inflammationrelated diseases, including inflammatory bowel disease, allergies, and autoimmunity, were effectively treated. Conclusions. This study finds that the therapy is being refined through experience and is now expanding to treat widespread neuropsychiatric problems such as depression, anxiety, migraine headaches, bipolar disorder, and perhaps Parkinson's disease.

“…Most scientific publications are case reports among travelers, immigrants (Gualdieri et al 2011), and adopted children (Di Lernia et al 2004;Marseglia et al 2007). H. diminuta is less commonly diagnosed but sporadically occurs in Asia and Europe (Wiwanitkit 2004;Patamia et al 2010). H. nana infections often remain asymptomatic.…”

FLOTAC for the diagnosis of Hymenolepis spp. infection: proof-of-concept and comparing diagnostic accuracy with other methods

Hymenolepis nana is the most common cestode parasitizing humans, yet it is under-diagnosed. We determined the optimal flotation solution (FS) for the diagnosis of this intestinal parasite with the FLOTAC method, and compared its diagnostic accuracy with an ether-concentration technique and the Kato-Katz method. Zinc sulphate (specific gravity 1.20) proved to be the best-performing FS. Using this FS, we detected 65 H. nana infections among 234 fixed fecal samples from Tajik and Sahrawi children (prevalence 27.8 %). The ether-concentration technique detected 40 infections (prevalence 17.1 %) in the same samples. Considering the combined results as a reference, the sensitivities of FLOTAC and ether-concentration were 95.6 % and 58.8 %, respectively. The Kato-Katz method resulted in a prevalence of only 8.7 %. In terms of eggs per gram of stool, a significantly (P <0.05) higher value was obtained with the FLOTAC and Kato-Katz techniques compared to ether-concentration. In another study carried out in China, the FLOTAC method detected six Hymenolepis diminuta infections in 302 fecal samples, whereas five samples were found positive with the Kato-Katz technique. We conclude that FLOTAC is an accurate coprodiagnostic technique for H. nana and H. diminuta, two species which join a growing list of intestinal parasites that can be reliably diagnosed by this technique.

“…In contrast, those infections in humans are rare. According to Genov (13) the incidence of H. diminuta infection in humans is sporadic and varies between 0.001% to 5.5% of the human population (14).…”

A field study was conducted to disclose the prevalence of different helminth parasites in the black rat, Rattus rattus, in some regions of Stara Zagora district, Bulgaria. Out of 67 examined rats, 53 (79.1%) were found to be positive. Helminths of three classes were detected such as Cestoda: Hymenolepis diminuta (47.8%), Hymenolepis nana (43.3%), Taenia taeniaeformis larvae (7.5%), Taenia polyacantha larvae (1.5%); Secernentea: Syphacia obvelata (4.5%), Aspiculuris tetraptera (3.0%) and Adenophorea: Capillaria hepatica (9.0%), Trichuris muris (3.0%). Of all the investigated rats, 27 (40.3%) were infected by one helminth species and 26 (38.8%) by more than one. Hymenolepis diminuta was a predominant species in cases of single infections (23.9%). The most frequent co-infections were observed by H. nana and H. diminuta (16.4%).
