BACKGROUND Syphilis, a sexually transmitted disease caused by spirochetal bacterium Treponema pallidum, can progress to affect the central nervous system, causing neurosyphilis. Accumulating evidence suggest that regulatory T cells (Tregs) may play an important role in the pathogenesis of syphilis. However, little is known about Treg response in… (More)
BACKGROUND/AIMS We investigated the clinical and cognitive features of patients with mild general paresis of the insane (GPI) in comparison to Alzheimer's disease (AD) patients, mild frontotemporal dementia (FTD) patients and normal elderly individuals. METHODS Twelve patients with mild GPI, 24 patients with mild AD, 11 patients with mild FTD and 36… (More)
BACKGROUND There is a wide variation in the reported prevalence of primary hyperhidrosis in the literature. Further, it is unknown if primary hyperhidrosis is a lifelong condition, or if demographical factors influence hyperhidrosis prevalence. OBJECTIVES This study aims to examine the prevalence of hyperhidrosis in multiple ethnic groups from two… (More)
BACKGROUND Treponema pallidum infection evokes vigorous immune responses, resulting in tissue damage. Several studies have demonstrated that IL-17 may be involved in the pathogenesis of syphilis. However, the role of Th17 response in neurosyphilis remains unclear. METHODOLOGY/PRINCIPAL FINDINGS In this study, Th17 in peripheral blood from 103… (More)
At present, diagnosis for neurosyphilis remains a major clinical challenge. Venereal Disease Research Laboratory (VDRL) titer of the cerebrospinal fluid (CSF) is suboptimally sensitive to diagnose neurosyphilis, which can be negative in neurosyphilis patients, especially in asymptomatic neurosyphilis patients. In the search for biomarkers of neurosyphilis,… (More)
Syphilis is a systemic sexually transmitted disease caused by Treponema pallidum ssp. pallidum (TPA). The origin and genetic background of Chinese TPA strains remain unclear. We identified a total of 329 single-nucleotide variants (SNVs) in eight Chinese TPA strains using next-generation sequencing. All of the TPA strains were clustered into three lineages,… (More)

The preferred drugs for the treatment of syphilis, benzathine and procaine penicillin, have not been available in Shanghai for many years, and currently, the incidence of syphilis is increasing. Alternative antibiotics for patients with syphilis during the benzathine and procaine penicillin shortage include macrolides. The failure of macrolide treatment in… (More)
