High incidence of precipitins in sera of heroin addicts. 1975

W R Smith, and I D Wells, and F L Glauser, and H S Novey

We analyzed sera of 50 consecutively hospitalized heroin-abuse patients for precipitins against several antigens. Forty-seven addicts had precipitins against extracts from moldy hay, and 34 against extracts from bagasse. Thirty-six showed precipitin bands against extracts from one or more of the following: Aspergillus, Micropolyspora faeni, and Thermoactinomyces vulgaris. These findings were significantly different from those of a control population (P less than .0001 for all antigens tested). The recent culture identification of bacteria and fungi from street heroin suggests that the addicted population may be injecting antigenic material intravenously, with subsequent antibody formation.

UI MeSH Term Description Entries
D007122 Immunoelectrophoresis A technique that combines protein electrophoresis and double immunodiffusion. In this procedure proteins are first separated by gel electrophoresis (usually agarose), then made visible by immunodiffusion of specific antibodies. A distinct elliptical precipitin arc results for each protein detectable by the antisera.
D007275 Injections, Intravenous Injections made into a vein for therapeutic or experimental purposes. Intravenous Injections,Injection, Intravenous,Intravenous Injection
D008297 Male Males
D008848 Micromonosporaceae A family of gram-positive, saprophytic bacteria occurring in soil and aquatic environments.
D011009 Pneumoconiosis A diffuse parenchymal lung disease caused by inhalation of dust and by tissue reaction to their presence. These inorganic, organic, particulate, or vaporized matters usually are inhaled by workers in their occupational environment, leading to the various forms (ASBESTOSIS; BYSSINOSIS; and others). Similar air pollution can also have deleterious effects on the general population. Bagassosis,Pneumoconioses
D011233 Precipitin Tests Serologic tests in which a positive reaction manifested by visible CHEMICAL PRECIPITATION occurs when a soluble ANTIGEN reacts with its precipitins, i.e., ANTIBODIES that can form a precipitate. Precipitin Test,Test, Precipitin,Tests, Precipitin
D011234 Precipitins Antibodies which elicit IMMUNOPRECIPITATION when combined with antigen. Immune Precipitates,Precipitates, Immune
