Serum samples from 22 patients with infective endocarditis were analysed for the presence of antibodies to cardiolipin, false positive Venereal Disease Research Laboratory (VDRL) test, and rheumatoid factor in order to determine the prevalence of anticardiolipin antibodies, their level, and to ascertain whether there was any correlation with the presence of rheumatoid factor. Although the latex test was positive in 10/22 (45%) patients, anticardiolipin antibodies, usually of a low level, were raised in only four (18%), and the VDRL test was positive in two patients in whom other antibodies were negative. These results show a clear discordance between these three tests, indicating that B cell production of these antibodies is separate and distinct. As with other infections which result in anticardiolipin antibody production, no thrombotic events were encountered.

Two young women (aged 32 and 25 years) with systemic lupus erythematosus and heart valve lesions in association with antiphospholipid antibodies are presented. In addition to the presence of the 'lupus anticoagulant' and false positive Venereal Disease Research Laboratory (VDRL) tests, both patients had high levels of IgG anticardiolipin antibodies. The first patient additionally had contraceptive induced chorea, chorea gravidarum, seven miscarriages, livedo reticularis, pulmonary embolism, and thrombocytopenia and developed culture negative endocarditis as well as hypertension. The second patient, who had presented with hypertension, developed aortic and mitral regurgitation, suspected myocarditis, manifested transient ischaemic attacks, and responded well to anticoagulation and steroid treatment.

Chlamydia trachomatis is being recognized as an important sexually transmitted disease in adolescents and young adults. This report reviews the recent literature regarding the many clinical entities encompassed by this organism; this includes urethritis and cervicitis as well as epididymitis, salpingitis, peritonitis, perihepatitis, urethral syndrome, Reiter syndrome, arthritis, endocarditis, and others. It is emphasized that many aspects of chlamydial infections parallel those of gonorrhea, including incidence, transmission, carrier state, reservoir, complications, (local and systemic), and others. A paragonococcal spectrum of sexual chlamydial disorders is discussed as well as effective antibiotic therapy. This microbiological agent must always be considered if venereal disease is suspected by the clinician in teenagers or adults. Mixed infections with Chlamydia trachomatis and Neisseria gonorrhoeae are common in both males and females. It may be preferable to treat gonorrhea with tetracycline to cover for this possibility.

Infection with Chlamydia trachomatis is an important cause of nongonococcal urethritis and cervicitis, and may be the most common sexually transmitted disease in the United States. Associated complications include epididymitis, proctitis, salpingitis, bartholinitis, arthritis, perihepatitis, and endocarditis. Perinatal transmission of infection may result in neonatal inclusion conjunctivitis and/or pneumonia of infancy. Chlamydial genital infection should be suspected in a patient (male or female) who presents with a gonorrhea-like syndrome but whose laboratory studies fail to demonstrate Neisseria gonorrhoeae. Such patients, together with their sex partners, should receive antichlamydial therapy; the uncomplicated genital infections respond well to oral treatment with tetracycline, erythromycin, and sulfonamide. The most important cause of treatment failure in nongonococcal urethritis is lack of simultaneous treatment of both patient and partner.

Non-specific urethritis (NSU) is a sexually transmitted disease; 50% of cases are due to Chlamydia trachomatis, so that this is the commonest sexually transmitted infection in the developed world. Chlamydial infection is now readily diagnosable and the evidence increasingly suggests that it is underdiagnosed. Chlamydial conjunctivitis (in the newborn baby or the adult) in the developed world is a complication of sexually transmitted genital infection by C trachomatis and it indicates a large reservoir of such infections. Because of the association of sexually transmitted diseases, systemic treatment for such chlamydial conjunctivitis should not be given until full genital and serological investigators have been carried out. Chlamydial infection causes serious complications (that were formerly often thought to be gonococcal), such as epididymitis in young men and salpingitis on young women. It may cause local complications in the eye of the newborn baby and even pneumonia in babies and fatal endocarditis in adults. The diagnosis of NSU should lead to the correct treatment of the male patient and of his sexual partners. It is the promiscuous woman, who does not have a regular sexual partner to report back to her that he has NSU, who is at particular risk of undiagnosed chlamydial infection. Routine genital investigations for chlamydia are particularly indicated in her case. Following the parallel of gonorrhoea, it seems that the use of contact tracers may be an effective method for controlling chlamydial infection.

With the decline in incidence of diphtheria in Europe and the USA, many laboratories no longer routinely culture throat swabs for Corynebacterium diphtheriae. However, there is an outbreak of infection with toxigenic strains in Russia and most adults do not have protective levels of antibody. Non-toxigenic strains are known to cause local disease and lysogenic conversion probably occurs in vivo as well as in vitro. Non-toxigenic C. diphtheriae var. gravis, formerly quite rare, has been isolated with increasing frequency in the UK over the last five years. During prospective screening at one Sexually Transmitted Disease Clinic, six (1%) of 578 homosexual men were found to harbour the organism in the throat, four of them with clinical pharyngitis. Only one of 1696 heterosexual men and women were found to be carriers. Seven cases of endocarditis due to this organism were reported in a single year in Sydney, Australia and non-toxigenic C. diphtheriae var. mitis has caused four cases of endocarditis in Switzerland. Non-toxigenic strains are responsible for pharyngitis and occasional invasive disease and should be treated. Routine screening of throat swabs should not be abandoned.

To identify prognostic indicators of survival at different CD4 cell levels, independent of highly active antiretroviral therapy (HAART), among injection drug users (IDUs). A community-recruited cohort of injection drug users followed semiannually from 1988 through 2000. Five partially overlapping subcohorts were defined by when participants first reached a CD4 cell level of 351 to 500, 201 to 350, 101 to 200, 51 to 100, or </=50 cells/microL. Prognostic factors were measured at entry into each category. Kaplan-Meier survival estimates for HIV-related death and Cox regression models were constructed by CD4 category. Among the 1030 HIV-infected IDUs, survival improved in the HAART-era with hazard ratios 0.42, 0.36, 0.24, 0.21, and 0.25, respectively, for CD4 cell groups of 500 to 351, 350 to 201, 200 to 101, 100 to 51, and </=50 cells/microL. Shorter survival was associated with prior hospitalization, AIDS, and sexually transmitted disease, with similar effects in the pre-HAART and HAART eras. For the lowest CD4 cell level, prior sepsis or endocarditis, outpatient/emergency room visits, and alcohol use provide additional prognostic value. Survival among HIV-infected IDUs improved since the introduction of HAART, even though utilization of HAART was incomplete. Clinical and behavioral variables provided prognostic information about survival, including substance use indicators.

Gardnerella vaginalis is typically associated with bacterial vaginosis in women. However, balanitis, urethritis, urinary tract infections and asymptomatic bacteraemia have also been described in men. Here we report a case of G. vaginalis septicaemia with infective endocarditis and septic emboli in the kidney and brain of an adult male.

Syphilis is a sexually transmitted disease caused by Treponema pallidum. Syphilitic aortitis might coexist in a dysfunctional aortic valve, but the etiology remains unclear, because microbiological diagnosis is difficult. A 62-year-old man with low-grade fever was diagnosed with aortitis and infective endocarditis, due to Treponema pallidum infection, using polymerase chain reaction analysis. This case suggests that syphilis might cause infective endocarditis.
