Leukemoid reaction (LR) is an uncommon though dreadful sign for the treating physician, as it is related to increased mortality. In the few series that have addressed its incidence and clinical significance, infectious causes count for about half of the cases of LR, the rest accounting for cancer, drugs or rarer causes. In the HIV setting, it represents an even rarer event, owing probably to the impaired granulocytic response of AIDS patients to bacterial agents. However no report exists as to the incidence of LR to the immune-restored HIV patients adequately treated with antiretroviral therapy (ART)...

Patients who present with papular rashes have a wide differential diagnosis particularly in the setting of immune compromise. A 30-year-old male diagnosed with HIV since 2009, never on antiretroviral therapy, with a nadir CD4 count of 333 cells/mm3 and a current viral load of 44,300 copies/mL, presented with a diffuse monomorphic papular eruption that began on his trunk and extremities and subsequently spread to the penis and scrotum, sparing the distal acral sites. A thorough infectious workup revealed a positive rapid plasma reagin (RPR) and varicella IgM and IgG antibodies...

The origin of nontreponemal antibodies during syphilis infection is hotly debated. Here, we analysed the immune response in rabbits immunized with various antigens. Inactivated treponemes elicited the production of low-titre nontreponemal antibodies in some rabbits. Cardiolipin combined with bovine serum albumin also induced anti-cardiolipin antibody production. These findings indicate that T. pallidum contained a cardiolipin antigen with weak immunogenicity. However, active T.pallidum induced higher nontreponemal antibody production with strong immunogenicity at an earlier time point, and the antibody titre was consecutive, suggesting the high nontreponemal antibody titre resulted from the combined effects of both the T...

The polarization of macrophages and the molecular mechanism involved during the early process of syphilis infection remain unknown. This study was conducted to explore the influence of Treponema pallidum (T. pallidum) treatment on macrophage polarization and the Akt-mTOR-NFκB signaling pathway mechanism involved in this process. M0 macrophages derived from the phorbol-12-myristate-13-acetate-induced human acute monocytic leukemia cell line THP-1 were cultured with T. pallidum. T. pallidum induced inflammatory cytokine (IL-1β and TNF-α) expression in a dose- and time-dependent manner...

Every year, an estimated 180 000 babies in the Western Pacific Region are infected by hepatitis B, 13 000 by syphilis and 1400 by HIV through mother-to-child transmission. ( 1 ) These infections can be largely prevented by antenatal screening, treatment and timely vaccination for newborns. Despite challenges in controlling each disease, major achievements have been made. National immunization programmes have reduced the regional hepatitis B prevalence from over 8% in 1990 to 0.93% among children born in 2012...

BACKGROUND: Human immunodeficiency virus (HIV) infection is associated with chronic immune activation, and concurrent sexually transmitted infections (STIs) may increase immune activation. OBJECTIVES: Because HIV-infected youth are at high risk of STIs and little is known about the impact of STIs on immune activation in HIV-infected youth, we conducted an exploratory study examining the association between STIs and systemic inflammation and immune activation among HIV-infected adolescents...

Flagellin is a classical pathogen-associated molecular pattern that can evoke robust immune response. We have demonstrated previously that three full-length flagellins of Treponema pallidum, namely FlaB1, FlaB2 and FlaB3, did have diagnostic value in serodiagnosis of syphilis. Here, we selected and constructed three recombinant fragments of each complete FlaB, both the conserved N-terminal and the C-terminal region, and the middle variable part, with the goal of exploring fragment unique to Treponema pallidum for use as antigen target in a fragment based serological test...

INTRODUCTION: During syphilis a compelling fight is engaged between the host's humoral and cellular immune responses that work to eliminate the infection and Treponema pallidum (T. pallidum) that manages to evade eradication and cause chronic infection. Different mechanisms are utilized by treponemes to overcome immunological response. Although penicillin (BPG) proved to be effective in quelling the early manifestations of the disease and consequently its contagiousness, questions remain about its ability to prevent the late complications and to provide a microbiological eradication in vivo...

Primary Zika virus (ZIKV) infections that occur during pregnancy can cause spontaneous abortion and profoundly disrupt fetal development. While the full range of developmental abnormalities associated with congenital Zika syndrome is not yet known, severe cases of the syndrome can present with microcephaly, extensive neurologic and ocular damage, and pronounced joint malformations. Animal models that accurately recapitulate congenital Zika syndrome are urgently needed for vaccine development and for the study of ZIKV pathogenesis...

Syphilis is a multi-stage, sexually transmitted disease caused by the spirochete Treponema pallidum ( Tp ). Considered broadly, syphilis can be conceptualized as a dualistic process in which spirochete-driven inflammation, the cause of clinical manifestations, coexists to varying extents with bacterial persistence. Inflammation is elicited in the tissues, along with the persistence of spirochetes to keep driving a robust immune response while evading host defenses; this duality is best exemplified during the florid, disseminated stage called secondary syphilis (SS)...

Treponema pallidum subspecies pallidum (T. pallidum) causes syphilis via sexual exposure or via vertical transmission during pregnancy. T. pallidum is renowned for its invasiveness and immune-evasiveness; its clinical manifestations result from local inflammatory responses to replicating spirochaetes and often imitate those of other diseases. The spirochaete has a long latent period during which individuals have no signs or symptoms but can remain infectious. Despite the availability of simple diagnostic tests and the effectiveness of treatment with a single dose of long-acting penicillin, syphilis is re-emerging as a global public health problem, particularly among men who have sex with men (MSM) in high-income and middle-income countries...

Syphilis is a chronic disease caused by Treponema pallidum and the pathogenesis is still unclear. T. pallidum infection induced inflammatory responses are involved in the immunopathological damage in skin and other tissues. Flagellin, the monomeric subunit of bacterial flagella, is a classic pathogen associated molecular patterns (PAMPs) that interacts to TLR5 and induces inflammatory responses. Keratinocytes, as immune sentinels recognize the PAMPs via TLRs, play an important role in skin innate immune response...
