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.

We would encourage construction of homes without carpets, wooden floors on stumps or weather board walls.

We assessed the influence of current indoor levels of fungi, house dust mite allergen (Der p 1), and cat allergen (Fel d 1) on sensitization and asthma in adults. A total of 485 adults answered a questionnaire and had skin prick tests and lung function tests. Dust and air samples were collected from their bedrooms. The dust was analyzed for Der p 1, Fel d 1, and fungal biomass (ergosterol). Fungal propagules were measured in air samples. Current asthma was defined as having wheezed during the past 12 mo plus bronchial hyperreactivity (BHR) to methacholine. High exposure to total airborne fungi was associated with increased BHR, but perhaps paradoxically with a lower risk of being sensitized to fungi. Ergosterol levels in floor dust were a risk factor both for being sensitized to fungi and having wheezed within the last year. High Fel d 1 levels in floor dust were found to increase the risk of being sensitized to cats and in beds to increase the risk of current asthma. Although Der p 1 levels in homes were high, people exposed to high Der p 1 levels in floor dust were less likely to be sensitized to house dust mites or to have wheezed within the past year. Current indoor levels of fungi and Fel d 1, but not Der p 1, influenced sensitization and asthma in adults with high dust mite exposure.

Validated instruments are not available to assess the residential characteristics. The aim of this study was to assess the reliability and validity of an interviewer-administered home visit report. The validity of 48 items in the Home Visit Report was examined against: observations made by a researcher, measurements of relative humidity, cat allergen, and ergosterol, a biomaker of fungal exposure and a biochemical test. Test-retest reliability of 10 fixed residential characteristics was assessed comparing the responses obtained in the main study with the pilot study, Kappa, ANOVA and Wilcoxon Rank Sum tests were applied to assess the agreement and P < 0.05 was considered as statistically significant. Among 44 items examined for the validity against observations, there was a perfect or almost perfect agreement in 21 (kappa = 0.9-1) and substantial agreement (kappa = 0.6-0.8) in 19. Higher cat allergen levels were observed with cat ownership and cat being allowed indoors. Observed condensation was associated with relative humidity and observed mould was associated with ergosterol levels. The agreement on the type of carpet and the test was substantial (kappa = 0.6). Among 10 items examined for reliability, there was a perfect or almost perfect agreement in 9 (kappa = 0.9-1) and substantial agreement (kappa = 0.7) in one. In conclusion, the Home Visit Report validated in this study provides reliable and valid data.
