Numerous studies have focused on lymphoma among patients infected with human immunodeficiency virus (HIV). However, little is known about the treatment options and survival rate of lymphoma in the Chinese people living with HIV (PLHIV). Our study aimed to investigate the prognosis and compare outcome of dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin, and rituximab (DA-EPOCH-R) with standard cyclophosphamide, doxorubicin, vincristine, prednisone and rituximab(R-CHOP) as front line therapy for PLHIV with diffuse large B-cell lymphoma (DLBCL) receiving modern combined antiretroviral therapy (cART).
A retrospective analysis evaluating PLHIV with DLBCL was performed in Shanghai Public Health Clinical Center from July 2012 to September 2019. The demographic and clinical data were collected, and overall survival (OS) and progression-free survival (PFS) analyses of patients receiving R-CHOP or DA-EPOCH-R therapy were performed by Kaplan-Meier analysis. Additionally, a Cox multiple in the modern cART era.
Outcomes of R-CHOP therapy do not differ from those of DA-EPOCH-R therapy. No HIV-related factors were found to be associated with the OS of PLHIV in the modern cART era.
Cryptococcal meningitis (CM) is one of the most common opportunistic infections caused by Cryptococcus neoformans in human immunodeficiency virus (HIV)-infected patients, and is complicated with significant morbidity and mortality. This study retrospectively analyzed the clinical features, characteristics, treatment, and outcomes of first-diagnosed HIV-associated CM after 2-years of follow-up.
Data from all patients (n = 101) of HIV-associated CM hospitalized in Shanghai Public Health Clinical Center from September 2013 to December 2016 were collected and analyzed using logistic regression to identify clinical and microbiological factors associated with mortality.
Of the 101 patients, 86/99 (86.9%) of patients had CD4 count <50 cells/mm, 57/101 (56.4%) were diagnosed at ≥14 days from the onset to diagnosis, 42/99 (42.4%) had normal cerebrospinal fluid (CSF) cell counts and biochemical examination, 30/101 (29.7%) had concomitant Pneumocystis (carinii) jiroveci pneumonia (PCP) on admission and 37/92 (4y in HIV-associated CM.
This study described the clinical features and outcomes of first diagnosed HIV-associated CM with 2-year follow-up data. Altered mental status and coinfection with PCP predicted mortality in HIV-associated CM.
Human immunodeficiency virus (HIV) prevalence among student men who have sex with men (MSM) in college is more than 5.0% and keeps on increasing in China. This study aims to clarify the proportion of HIV recent infection, its propeller and the source among college student MSM.
We conducted a multicenter cross-sectional study in seven major Chinese cities during 2012-2013. HIV recent infections (≤ 168 days) and incidence was measured and estimated by BED HIV-1 capture enzyme immunoassay (BED-CEIA) testing strategy. HIV-related behaviors and transmitted drug resistance (TDR) were investigated and compared between the college student MSM, <25-year-old non-student youth MSM (NSYM), and ≥25-year-old non-student non-youth MSM (NSNYM), using structured survey, and analyses of drug resistance.
Overall, 4,496 (4496/4526, 99.3%) were eligible for enrollment, comprising 565 college student MSM, 1,094 NSYM, and 2,837 NSNYM. The proportion of HIV recent infection were 70.3% (26/37), 50.8% (65/128) and 35.1% (95/271), the HIV incidence rate were 10.0 (95% CI 6.2-13.9)/100PY, 12.9 (95% CI 9.8-16.1)/100PY, 6.8 (95% CI 5.4-8.2)/100PY, and TDR prevalence were 7.4% (2/27), 2.0%, (2/98) and 4.9% (11/226), among student MSM, NSYM, and NSNYM, respectively. Among HIV positive student MSM with age< 21-year-old, the proportion of HIV recent infection is 90.9% (10/11). Factors independently associated with HIV recent infection in student MSM was usage of recreational drug in the past 6 months (AOR 2.5; 95% CI 1.0-5.8).
College student MSM had higher proportion of HIV recent infection and TDR than the youth and older MSM in China during 2012-2013. The HIV infections were more likely to happen during the early year of college life among student MSM.

Transplant glomerulopathy (TG) is a pathologic feature of chronic active antibody-mediated rejection (cAMR) and is associated with renal allograft failure. The specific role of B cells in the pathogenesis of TG is unclear.
We utilized a minor mismatched rat kidney transplant model with B cell deficient recipients, generated by CRISPR/Cas9 technology, to investigate the impact of B cell depletion on the pathogenesis of TG. We hypothesized B cell deficiency would prevent TG in the rat kidney transplant model of cAMR. Treatment groups included syngeneic, allogeneic, sensitized allogeneic, and B cell deficient allogeneic transplant recipients.
B cell deficient recipients demonstrated reduced TG lesions, decreased microvascular inflammation, reduced allograft infiltrating macrophages, and reduced IFNγ transcripts within the allograft. Allograft transcript levels of IFNγ, MCP, and IL-1β correlated with numbers of intragraft macrophages. B cell deficient recipients lacked circulating donor-specific antibodies and had an increased splenic T regulatory cell population.
In this model of cAMR, B cell depletion attenuated the development of TG with effects on T cell and innate immunity.

Transplant recipients who develop COVID-19 may be at increased risk for morbidity and mortality. Determining the status of antibodies against SARS-CoV-2 in both candidates and recipients will be important to understand the epidemiology and clinical course of COVID-19 in this population. While there are multiple tests to detect antibodies to SARS-CoV-2, their performance is variable. Tests vary according to their platforms and the antigenic targets which make interpretation of the results challenging. see more Furthermore, for some assays, sensitivity and specificity are less than optimal. Additionally, currently available serological tests do not exclude the possibility that positive responses are due to cross reactive antibodies to community coronaviruses rather than SARS-CoV-2.
This study describes the development and validation of a high-throughput multiplex antibody detection assay.
The multiplex assay has the capacity to identify, simultaneously, patient responses to 5 SARS-CoV-2 proteins, namely, the full spike protein, 3 individual domains of the spike protein (S1, S2, and receptor binding domain), and the nucleocapsid protein.
