Syphilis: Review with Emphasis on Clinical, Epidemiologic, and Some Biologic Features

Abstract: Syphilis is a chronic disease with a waxing and waning course, the manifestations of which have been described for centuries. It occurs worldwide, and the incidence varies significantly with geographic location. Transmission is mainly by sexual contact. The causative organism, Treponema pallidum, was first described in 1905, but because of the inability to culture the organism and the limitations of direct microscopy, serologic testing is the mainstay of laboratory diagnosis. The disease has been arbitrarily divided into several stages. The primary stage is defined by a chancre at the site of inoculation. The secondary stage is characterized by a polymorphic rash, lymphadenopathy, and other systemic manifestations. A variable asymptomatic latent period follows, which for epidemiologic purposes is divided into early ( 1 year) stages. The early stages (primary, secondary, and early latent) are potentially infectious. The tertiary stage is the most destructive and is marked by cardiovascular and neurologic sequelae and gummatous involvement of any organ system. Congenital infection may result in protean early or late manifestations. Unlike many other bacteria causing infectious diseases, the organism remains sensitive to penicillin, and this remains the mainstay of therapy.

A Randomized Trial of Enhanced Therapy for Early Syphilis in Patients with and without Human Immunodeficiency Virus Infection

Abstract: Background Reports of neurosyphilis and invasion of cerebrospinal fluid by Treponema pallidum in patients with human immunodeficiency virus (HIV) infection have led to doubts about the adequacy of the recommended penicillin G benzathine therapy for early syphilis. Methods In a multicenter, randomized, double-blind trial, we assessed two treatments for early syphilis: 2.4 million units of penicillin G benzathine and that therapy enhanced with a 10-day course of amoxicillin and probenecid. The serologic and clinical responses of patients with and without HIV infection were studied during one year of follow-up. Results From 1991 through 1994, 541 patients were enrolled, including 101 patients (19 percent) who had HIV infection but differed little from the uninfected patients in their clinical presentations. The rates at which chancres and rashes resolved did not differ significantly according to treatment assignment or HIV status. Serologically defined treatment failures were more common among the HIV-infect...

Treatment of the early manifestations of Lyme disease

Abstract: During 1980 and 1981, we compared antibiotic regimens in 108 adult patients with early Lyme disease. Erythema chronicum migrans and its associated symptoms resolved faster in penicillin- or tetracycline-treated patients than in those given erythromycin (mean duration, 5.4 and 5.7 versus 9.2 days, F = 3.38, p less than 0.05). None of 39 patients given tetracycline developed major late complications (meningoencephalitis, myocarditis, or recurrent attacks of arthritis) compared with 3 of 40 penicillin-treated patients and 4 of 29 given erythromycin (chi square with 2 degrees of freedom = 5.33, p = 0.07). In 1982, all 49 adult patients were given tetracycline; again, none of them developed major complications. However, with all three antibiotic agents nearly half of the patients had minor late symptoms such as headache, musculoskeletal pain, and lethargy. These complications correlated significantly with the initial severity of illness. For patients with early Lyme disease, tetracycline appears to be the most effective drug, then penicillin, and finally erythromycin.

Effect of Human Immunodeficiency Virus (HIV) Infection on the Course of Syphilis and on the Response to Treatment

Abstract: Purpose: To evaluate evidence that concurrent infection with human immunodeficiency virus (HIV) alters both the natural history of syphilis (by increasing the frequency of early neurosyphilis) and ...

European guideline for the management of syphilis

Abstract: Syphilis is classi® ed as acquired or congenital. Acquired syphilis is divided into early and late syphilis. Early syphilis: primary, secondary and early latent (Centers for Disease Control [CDC]: acquired 51 year previously1; World Health Organization [WHO]: acquired 52 years previously2). Late syphilis: late latent (CDC: acquired 51 year previously1; WHO: acquired 52 years previously2), tertiary, including gummatous, cardiovascular and neurosyphilis (the latter two are also sometimes classi® ed as quartenary syphilis). Congenital syphilis is divided into early (® rst 2 years of life) and late (apparent later in life), which includes the stigmata of congenital syphilis.
