A TYPICAL EXTENSIVE GENITAL ULCER IN FULL BLOWN AIDS WITH SLIM DISEASE
Background: Atypical and exceptional clinical presentation of full blown AIDS may be observed in sub-Saharan Africa. We report herein the case
of a Central African 37-year-old male patient presented with full blown AIDS, a typical picture of slim disease with marked cachexia and wasting
faces. In addition, the patient was suffering from very extensive genital ulcer with complete loss of substance of the genitalia.
Methods: Extensive histological and microbiological analysis of the genital lesion was carried out.
Results: HIV-1 serology was positive, the HIV-1 RNA plasma viral load was 5.3 log copies/ml and CD4 T cell count was 1 per μL. Search for
Mycobacterium tuberculosis in sputum and urine was negative by direct microscopic examination with Ziehl-Neelsen staining. Testing for syphilis
serology was negative. Direct immunofluorescence detection on genital ulcer scraping was negative for Chlamydia trachomatis and Treponema
pallidum. Furthermore, the infections with Haemophilus ducreyi and Chlamydia trachomatis were excluded by PCR on genital swabs.Genital PCR
was positive for herpes simplex virus (HSV) type 2. Marked improvement was observed within 6 weeks after starting empirical therapy including
first-line antiretroviral therapy, cotrimoxazole, doxycycline and valacyclovir, with progressive healing of genital ulcer and negativity of HSV PCR.
Conclusion: Taken together, the extensive genital ulcer in this patient is likely the result of a multifactorial process, involving both profound cellular
immune depression and complex genital infectious process in which herpetic infection may have participated as a chronic worsening co-factor
Episodic Therapy for Genital Herpes in Sub-Saharan Africa: A Pooled Analysis from Three Randomized Controlled Trials
BACKGROUND: A randomized controlled trial in South Africa found a beneficial effect of acyclovir on genital ulcer healing, but no effect was seen in trials in Ghana, Central African Republic and Malawi. The aim of this paper is to assess whether the variation in impact of acyclovir on ulcer healing in these trials can be explained by differences in the characteristics of the study populations. METHODOLOGY/PRINCIPAL FINDINGS: Pooled data were analysed to estimate the impact of acyclovir on the proportion of ulcers healed seven days after randomisation by HIV/CD4 status, ulcer aetiology, size and duration before presentation; and impact on lesional HIV-1. Risk ratios (RR) were estimated using Poisson regression with robust standard errors. Of 1478 patients with genital ulcer, most (63%) had herpetic ulcers (16% first episode HSV-2 ulcers), and a further 3% chancroid, 2% syphilis, 0.7% lymphogranuloma venereum and 31% undetermined aetiology. Over half (58%) of patients were HIV-1 seropositive. The median duration of symptoms before presentation was 6 days. Patients on acyclovir were more likely to have a healed ulcer on day 7 (63% vs 57%, RR = 1.08, 95% CI 0.98-1.18), shorter time to healing (p = 0.04) and less lesional HIV-1 RNA (p = 0.03). Small ulcers (<50 mm(2)), HSV-2 ulcers, first episode HSV-2 ulcers, and ulcers in HIV-1 seropositive individuals responded best but the better effectiveness in South Africa was not explained by differences in these factors. CONCLUSIONS/SIGNIFICANCE: There may be slight benefit in adding acyclovir to syndromic management in settings where most ulcers are genital herpes. The stronger effect among HIV-1 infected individuals suggests that acyclovir may be beneficial for GUD/HIV-1 co-infected patients. The high prevalence in this population highlights that genital ulceration in patients with unknown HIV status provides a potential entry point for provider-initiated HIV testing
