Unusual presentation of early lymphogranuloma venereum in an HIV-1 infected patient: effective treatment with 1 g azithromycin

The incidence of lymphogranuloma venereum (LGV) is low in the western world. Early LGV is characterised by bubonic disease following a painless papule or small ulcer. We report a white bisexual male who presented with a painful perianal ulcer, inguinal lymphadenitis, and concomitant infection with human immunodeficiency virus 1 (HIV-1). Chlamydia trachomatis serovar L2 was identified as the cause after polymerase chain reaction and genotyping the major outer membrane protein by restricted fragment length polymorphism. Treatment with a single dose of 1 g azithromycin was effective. This case illustrates that early LGV may mimic other genital ulcer diseases, such as genital herpes or chancroid, especially in HIV infected patients. In the western world, LGV must still be included in the differential diagnosis of bubonic disease with or without sexually acquired ulcers.

European guideline for the management of genital herpes, 2010

This is the guideline for genital herpes simplex virus (HSV) management for the IUSTI/WHO Europe, 2010. They describe the epidemiology, diagnosis, clinical features, treatment and prevention of genital HSV infection. They include details on the management of HSV in pregnancy, those who are immunocompromised and the clinical investigation and management of suspected HSV-resistant disease.

Epidemiology of genital chlamydial infections in patients with chlamydial conjunctivitis; a retrospective study

OBJECTIVE: To determine how often chlamydial conjunctivitis is accompanied by a genital chlamydial infection and if there is a correlation between the dominant hand and the eye first infected. METHODS: We retrospectively studied the records of 65 patients with chlamydial conjunctivitis who were referred to the Outpatient Department of Sexually Transmitted Diseases (STD) of the University Hospital Rotterdam by ophthalmologists of the Eye Hospital Rotterdam. The patients have recently been asked by letter if they were left- or right-handed. RESULTS: Twenty of the 37 men (54%) had a positive chlamydial urethral culture. Seventy per cent of these men had no genital symptoms. Eight of the 37 men (22%) had a non-specific urethritis (NSU). Twenty of the 27 women examined (74%) had a positive chlamydial cervical culture. Sixty per cent of these women had no genital symptoms. Eight women with a genital chlamydial infection also had another genital infection. Five women without a genital chlamydial infection had another genital infection. Two women had no genital infection at all. A correlation between the eye infected and left- or right-handedness of the patient could not be found. CONCLUSIONS: A considerable percentage of the patients with a chlamydial conjunctivitis had a concomitant genital chlamydial infection. The majority of them had no genital symptoms. Since patients with chlamydial conjunctivitis and/or their partners possibly have a concomitant genital chlamydial infection, we recommend referral of both patients and sexual partners to an STD clinic for routine examination and systemic treatment when indicated.

Topical treatment of recurrent genital herpes simplex virus infections with trisodium phosphonoformate (foscarnet): double blind, placebo controlled, multicentre study.

A double blind, placebo controlled trial was performed in nine sexually transmitted diseases (STD) clinics in the United Kingdom and the Netherlands to investigate the efficacy of trisodium phosphonoformate (foscarnet) cream in treating recurrent genital herpes simplex virus (HSV) infection. The study group comprised 145 male and 85 female patients. Men received 0.3% foscarnet cream and women 1% foscarnet cream for five days. The difference in time to healing between patients receiving foscarnet or placebo was not significant. Fewer patients treated with foscarnet had positive viral cultures after treatment, but the difference was not significant. The development of new lesions, however, was significantly less common in patients given foscarnet. Though topical foscarnet is a safe drug, no appreciable efficacy in treating recurrent genital HSV infection could be shown.

The incidence of neonatal herpes in The Netherlands.

BACKGROUND In The Netherlands the incidence of neonatal herpes was 2.0-2.9 per 100,000 live births during the period 1981-1998. The low incidence warranted a rather conservative prevention policy. OBJECTIVES To monitor for potential changes in the incidence of neonatal herpes in The Netherlands between 1999 and 2005, which may affect the prevention policy. STUDY DESIGN Questionnaires were sent to all virological laboratories, the gynaecological and paediatric departments of every university hospital and half the number of the general hospitals in The Netherlands. The questionnaires pertained to the incidence of proven cases of neonatal herpes, the numbers of caesarean sections performed for the prevention of neonatal herpes and the numbers of pregnant women with genital herpes. RESULTS In the period 1999-2005 33 cases of neonatal herpes were reported, yielding an incidence of 3.2 cases per 100,000 live births per year. The estimated annual numbers of pregnant women with genital herpes ranged from 200 to 240. Approximately 9 caesarean sections were performed annually to prevent neonatal herpes. CONCLUSIONS In The Netherlands neonatal herpes is still a rare condition. From the findings of this study it is concluded that it is not necessary to revise the Dutch guidelines for the prevention of neonatal herpes simplex infection.

Analysis of rectal Chlamydia trachomatis serovar distribution including L2 (lymphogranuloma venereum) at the Erasmus MC STI clinic, Rotterdam

Objectives: Compared to urogenital infections, little is known of serovar distribution in rectal chlamydial infection. The aim of this study was to explore possible relations between demographics, sexual behaviour, clinical manifestations, rectal symptoms, and chlamydial serovars including L2 (lymphogranuloma venereum). Methods: Genotyping was done prospectively in all rectal chlamydial infections since the outbreak of proctitis caused by lymphogranuloma venereum in February 2003. 33 (15.1%) rectal Chlamydia trachomatis infections from the years 2001 and 2002 were genotyped retrospectively. Results: Of all 219 rectal chlamydial infections, detected in the period July 2001 to August 2005, a total of 149 (68.0%) were successfully genotyped including 21 (14.1%) infections with serovar L2. In univariable and multivariable analyses, L2 serovar positive patients were significantly more often HIV positive (p = 0.002; OR: 6.5; 95% CI: 2.0 to 21.1), and had had sex in the past 6 months with more partners compared to other serovars. Furthermore, patients with L2 proctitis presented far more often with self reported rectal symptoms (p<0.005; OR: 19.4; 95% CI: 4.9 to 77.0) and clinical manifestations (p<0.005; OR: 15.4; 95% CI: 4.5 to 52.5). Conclusions: Chlamydial infections with serovar L2 show a different clinical and epidemiological pattern compared to serovar D-K. LGV proctitis is significantly associated with HIV positivity and a high number of sexual partners and causes more rectal symptoms and clinical manifestations. Neither young age nor ethnicity were identified as risk factors for any of the serovars investigated in this study.

Sensitivity and specificity of three new commercially available Chlamydia trachomatis tests.

In order to determine the value of new Chlamydia trachomatis (Ct) specific tests for routine serological diagnosis of Ct infections, we evaluated several commercially available assays (C. trachomatis enzyme immunoassay (EIA), Labsystems (CtL); SeroCT, Savyon (CtS); pELISA, Medac (CtMp)) in various study populations. The prevalence of C. trachomatis-specific IgA antibodies in a blood donor population (n=443) as determined by the peptide based tests CtL, the CtS and the CtMp was 5%, while for IgG antibodies this was 6% (CtL and CtS) and 12% (CtMp) respectively. Prevalence was negatively correlated with age, concording with C. trachomatis specificity. None of the three tests showed significant titre rises in serum samples taken from patients with a proven infection of Chlamydia pneumoniae (n=22), indicating species-specificity for all three tests. In patients with a polymerase chain reaction proven (n = 324) Ct infection, 75%, 70% and 68% were positive for IgG and 45%, 38% and 47% positive for IgA as determined by the CtMp, CtL and CtS respectively. We conclude that the new synthetic peptide-based EIA tests are able to detect species-specific Ct antibodies, which are strongly correlated to (active) infection.

Can group B streptococci cause symptomatic vaginitis

BACKGROUND: Maternal cervicovaginal colonization with Lancefield group B streptococci (GBS) is an important risk factor for neonatal morbidity and mortality. About 15% of women are carriers of GBS. Usually, they are asymptomatic. CASES: We describe two patients with symptomatic vaginitis for which no apparent cause was found. Both patients were heavily colonized with GBS. After antibiotic treatment, both became asymptomatic and culture negative, but after recolonization with GBS, symptoms resumed. This phenomenon was repeatedly observed. After emergence of resistance to antibiotics, local application of chlorhexidine appeared to be the only useful treatment. CONCLUSION: We hypothesize that GBS-vaginitis may be a possible disease entity. Although at present it is not clear why some patients become symptomatic, we speculate that the immunologic response is somehow selectively hampered in such patients.

Prevalence of STD and HIV infections among attenders of the Erasmus MC STD clinic, Rotterdam, The Netherlands, during the years 1996 to 2000

The purpose of the study was to investigate possible changes in the prevalence of STD and HIV collected at a Dutch STD clinic in the period 1996 to 2000. Age, gender, ethnic background, sexual preference, intravenous drug use and STD or HIV infection in persons attending an STD outpatient clinic were analysed and compared. The prevalence of HIV infection among the clinic visitors remained stable. The prevalence of Neisseria gonorrhoeae and Chlamydia trachomatis infections increased significantly among heterosexual men and heterosexual women. Among homo- and bisexual men a significant increase was seen in chlamydial infections only. Because of the increasing prevalence of gonococcal and chlamydial infections among STD clinic visitors in Rotterdam, more attention should be paid to coordinated preventive activities, such as health education and contact tracing. Further subgroup analyses should be done in order to get more information on risk behaviour in the different groups.

European guideline for the management of tropical genito-ulcerative diseases

. Causative pathogen: the gram-negative, facultative anaerobic bacillus Haemophilus ducreyi . Chancroid is common in several areas of the world including Africa, the Caribbean and Southwest Asia. In Kenya, Gambia and Zimbabwe, chancroid is considered the most common cause of genital ulceration . In European countries epidemics, generally limited, may occur, the source often being found in a commercial sex setting.
