Разоблачение иммунитета хламидии трахоматис в врожденных секрециях: систематический обзор.

Хламидиотрахоматис (CT) — широко распространенная бактериальная инфекция, передающаяся половым путем (ИППП), связанная с тяжелыми заболеваниями. КТ нацелена на уникальную иммунологическую среду: эпителий гениталия. Хотя выборка гениталий сопряжена с трудностями, предыдущие исследования показали, что антитела, относящиеся к гениталиям, демонстрируют повышенную нейтрализующую способность по сравнению с антителами сыворотки. Кроме того, клетки памяти Т (TRM) обеспечивают более высокую степень защиты по сравнению с циркулирующими Т клетками. Однако необходимы дополнительные исследования для выявле

Refractory and/or Relapsing Cryptococcosis Associated with Acquired Immune Deficiency Syndrome: Clinical Features, Genotype, and Virulence Factors of Cryptococcus spp. Isolates.

Refractory and relapsing crytocococcosis in acquired immune deficiency syndrome (AIDS) patients have a poor prognosis. The risk factors for this complicated infection course were evaluated by comparing refractory and/or relapsing cryptococcosis in human immunodeficiency virus-coinfected patients (cohort 1) with another group of AIDS patients who adequately responded to antifungals (cohort 2). Except for one isolate of Cryptococcus gattii from a cohort 2 case, all other isolates were identified as Cryptococcus neoformans var. grubii, sex type α, genotype VNI, including Cryptococcus reisolated f

Direct-acting antiviral drugs for the treatment of chronic hepatitis C virus infection: Interferon free is now.

Chronic hepatitis C (CHC) is a global, serious, and life-threatening disease. Virologic response at 12 weeks post-treatment (SVR12) signifies a durable virologic response and is currently the primary efficacy endpoint used in registrational trials. This change led to more rapid clinical development and earlier approvals of highly effective and well-tolerated therapies, facilitating access to those in need. Hepatitis C virus (HCV) infection is a therapeutic area where mathematical modeling has proven helpful in understanding the drug mechanism and characterizing viral kinetics to inform therapy

Herpes Simplex [corrected] Virus Type 2 Shedding From Male Circumcision Wounds in Rakai, Uganda.

A prospective observational study of 176 men coinfected with human immunodeficiency virus and herpes simplex virus type 2 (HSV-2) was conducted to assess whether their sexual partners may be at an increased risk of HSV-2 from male circumcision (MC) wounds. Preoperative and weekly penile lavage samples were tested for penile HSV-2 shedding. Prevalence risk ratios (PRRs) were estimated using Poisson regression. Detectable penile HSV-2 shedding was present in 9.7% of men (17 of 176) before MC, compared with 12.9% (22 of 170) at 1 week (PRR, 1.33; 95% confidence interval [CI], .74-2.38) and 14.8%

Opportunistic DNA Recombination With Epstein-Barr Virus at Sites of Control Region Rearrangements Mediating JC Virus Neurovirulence.

We document a unique DNA recombination between polyomavirus JC (JC virus [JCV]) and Epstein-Barr virus (EBV) at sequences of JCV found infecting the brain. Archetype JCV is present in bone marrow and uroepithelial cells of most adults. During immunosuppression, JCV can infect the brain, causing a demyelinating disease, progressive multifocal leukoencephalopathy. Rearrangements in the archetype noncoding control region are necessary for neurovirulence. Two NCCR deletions and a duplication occur at sequences of homology with EBV, present latently in B cells, which may be coinfected with both vir
