Gonorrhea and the beginnings of clinical research ethics.
Research on ocular inflammation associated with gonorrhea began in conjunction with the entry of trachoma into Europe during the Napoleonic wars. The initial questions involved the cause of the contagiousness of gonorrhea and how the contagion spreads from the genitalia to other sites. Because efforts to infect animals with gonorrheal matter were unsuccessful, all experiments were conducted on human subjects. Once these two causes of blindness were tentatively differentiated, attempts to restore vision in an eye that had been blinded by a trachomatous membrane over the cornea by instilling gonorrheal pus began to be practiced. In 1841, Joseph Piringer described his use of this method to determine infectiousness decades before the discovery of pathogenic bacteria, as well as ethical concerns about the associated endangerment of patients. Beginning in the 1880s, research focused on the identification of the gonococcus and assessment of its pathogenicity. The ethical dilemma of inducing a disease with an unpredictable outcome persisted until the 1940s, when gonorrhea could be reliably cured by penicillin.
