Current standards for diagnosis and treatment of syphilis : selection of some practical issues, based on the European (IUSTI) and U.S. (CDC) guidelines

Syphilis continues to be an important epidemiologic problem. For a few years a steady increase in the incidence of this sexually transmitted disease has been observed. Advances in medical science obligate the doctor to use only such diagnostic and therapeutic approaches that are scientifically proven. Based on the European (IUSTI) and U.S. (CDC) guidelines, in this manuscript, we present some selected practical issues concerning diagnosis and treatment of syphilis. We truly hope that the present review will help all doctors taking care of syphilitic patients to systematize the current knowledge

Pityriasis lichenoides-like secondary syphilis and neurosyphilis in a HIV-infected patient

Papulo- and vesiculo-necrotic lesions are rare manifestations of secondary syphilis. Until now it has been described only in HIV-infected patients with advanced stages of immunosuppression. This case report describes an unusual case of PLEVA-like syphilis in a 33-year-old man with newly diagnosed HIV infection. Despite that the CD4 cells level and viral load did not indicate the advance stage of immunosuppression, the unusual manifestation of syphilis and neurosyphilis occurred. The presented case indicates the need for HIV screening in every patient with syphilis especially when the clinical manifestation is unusual. Importance of syphilis testing in every case with atypical rashes should be also highlighted

HIV infection and sex in sex-on-premises venues are associated with a higher risk of syphilis reinfection among men who have sex with men

Introduction: Recent outbreaks of syphilis occurred predominantly in men who have sex with men (MSM). A significant proportion of syphilis cases occur in MSM who had more than one episode of syphilis. This group may play an important role in syphilis transmission. Aim: To identify factors associated with the risk of syphilis reinfection. Material and methods: Forty-four MSM patients with the first episode of syphilis who were treated at the Department of Dermatology at the Jagiellonian University School of Medicine in Krakow, Poland were included in this study. After completing the treatment, the RPR testing was done every 3 months for 2 years in every patient. In the study period, we identified 12 (22%) cases of syphilis reinfection, eight of which were asymptomatic. Clinical, demographic and behavior data from patients with only one episode of syphilis were compared with those collected from repeaters. Results: Individuals with syphilis reinfection had concomitant HIV infection more frequently, reported a higher number of sexual partners and had sex in sex on premises venues more frequently (p < 0.05). In the multivariate analysis, we found that being HIV-infected MSM and having sex in sex on premises venues independently correlated with a higher risk of syphilis reinfection (OR = 9.6, 95% CI: 2.2-42.5 and OR = 5.6, 95% CI: 1.4-22.5, respectively). Conclusions: Results of our study highlight a strong need for frequent and repeated screening among MSM patients (especially those with concomitant HIV infection) with the first episode of syphilis and taking detailed patient’s history regarding also demographic and behavior data. We should also improve prevention policies to reduce risk behaviors in this population

Clinical study on single-organ cutaneous small vessels vasculitis (SoCSVV)

Leukocytoclastic vasculitis (LCV) is a heterogenous group of disorders that may manifest as a mild disease isolated to the skin or be a part of life-threatening systemic vasculitis. According to the 2012 Chapel Hill Consensus Conference nomenclature, patients presenting symptoms of LCV confined only to the skin should be defined as suffering from a single-organ cutaneous small vessel vasculitis (SoCSVV). SoCSVV is a benign disease with a good clinical outcome but with a significant risk of relapse and skin ulcer formation. The aim of the current study was to characterize SoCSVV and to identify factors that may be associated with the risk of recurrence and skin ulcers. Medical records of patients with LCV hospitalized at the Department of Dermatology at University Hospital in Cracow in the years 2010 to 2015 were analyzed. A total of 24 patients fulfilled criteria of SoCSVV. Drugs and preceding infections were identified as precipitating factors in 40% and 20% of cases, respectively. Skin lesions other than palpable purpura (i.e., macules, urticarial vasculitis, or ulcers) were identified in almost half of the patients. Interestingly, the presence of macules independently increased the risk of skin ulcer formation (odds ratio = 16; 95% confidence interval: 1.5–176.6; P = 0.0075) in the multivariate logistic regression analysis. One-quarter of patients with SoCSVV experienced relapse during the 6-month follow-up. The greater number of affected skin areas was an independent risk factor of recurrence (odds ratio = 5; 95% confidence interval: 2–45; P = 0.02). SoCSVV was usually associated with drugs and preceding infections. The disease relapses in approximately one-quarter of the patients. The more severe the skin involvement in the course of SoCSVV, the higher is the risk of recurrence

Expression of metalloproteinases (MMP-2 and MMP-9) in basal-cell carcinoma

The aim of this study was to compare the expressions of mRNA for metalloproteinases (MMP-2 and MMP-9) and type IV collagen in two different histological types of basal-cell carcinoma (BCCs; nodular and infiltrative) and in normal tissues from the tumor interface. The study included biopsy specimens of the skin involved with BCC and normal skin adjacent the lesion. The expressions of mRNA for MMP-2, MMP-9 and type IV collagen were determined by means of RT-PCR (Reverse transcription polymerase chain reaction). The level of type IV collagen mRNA in nodular and infiltrative BCCs turned out to be significantly lower, and the expressions of MMP-2 and MMP-9 mRNA significantly higher than in normal tissues adjacent to these tumors. The expression of mRNA for MMP-9 but not for MMP-2 was significantly higher in infiltrative BCCs than in the nodular BCCs. In turn, normal tissues adjacent to nodular BCCs showed significantly higher levels of mRNA for MMP-2 and significantly lower levels of type IV collagen mRNA than the normal tissues from the interface of infiltrative BCCs. The findings suggest that MMP-2 and MMP-9 could be used as prognostic factors of BCCs
