The prevalence of atopy among patients having chronic fatigue syndrome (CFS) has been reported to be as high as 80% in published surveys of patients with this syndrome. However, many of the reports relied on self-assessment by patients for the presence of atopy or solely used total immunoglobulin E (IgE) levels to assess the likelihood of atopy. To more critically assess the presence of atopy among patients with CFS, testing was done for total IgE and allergen-specific IgE using the Pharmacia CAP system including 20 common allergens: trees (birch/oak/ash), grass (rye/blue), weeds (common/giant ragweed), molds (Penicillium/Aspergillus/Alternaria), dust mites (Dermatophagoides pteronyssinus/Dermatophagoides farinae), animal dander (cat/dog), and foods (egg white/milk/wheat/corn/peanut/shrimp). Testing of 50 patients having documented CFS indicated that 78% had total IgE < 100 IU/mL, among whom 26% had a positive test for allergen-specific IgE of class I or greater for one or more allergens. Among the 22% of CFS patients having a total IgE > 100 IU/mL, 73% had a positive test for allergen-specific IgE for one or more allergens. The most commonly positive allergens were dust mites (24-26%), whereas molds (0-6%) and foods (0-4%) were rarely positive. The overall frequency of positive results for the presence of allergen-specific IgE among CFS patients was 36%, not significantly different from the normal prevalence of these antibodies in the general population (20-35%). This assessment of the prevalence of allergen-specific IgE antibodies in patients with CFS fails to support a potential association between CFS and atopy.

Wastewater treatment by-products (WTBP), such as sewage sludge (SS) may be used to enhance soil chemical, physical, and biological properties. These enhanced soil properties, in turn, could from its source of production to its site of application. These concerns may be mitigated by incineration of the SS to produce ash (SSA) and dissolved in water and stored in ponds as contribute to an increase in plant growth, production, mineral nutrition. Some SS is difficult to handle due to bad odor in its raw state and has large mass, hence expensive for transportation weathered SSA (WSSA). A greenhouse study was conducted using Candler fine sand CFS; (CFS; pH = 6.8) and Ogeechee loamy sand OLS; (pH = 5.2) with application of either 0, 24.7, 49.4, 98.8, or 148.2 Mg ha(-1) as either SS, SSA, or WSSA to evaluate the biomass production and elemental composition responses of sorghum-sudan grass (Sorghum vulgaris var. Sudanese hitche). Shoot and root biomass were 2 to 3 fold greater in the soil amended with SS, than either SSA or WSSA. Concentrations of nutrient and trace elements in the shoots and roots increased with increasing rates of amendments. Application of these by-products up to 98.8 Mg ha(-1) rate did not adversely affect growth or accumulation of trace elements in sorghum-sudan grass. Long-term field studies are recommended to investigate the potential leaching of various elements from the amended soils in addition to evaluation of plant growth and production responses to determine the acceptable rates of these by-products as amendments to agricultural soils.
