Oprea C, Ianache I, Vasile S, Costescu C, Tardei G, Nica M, Umlauf A, Achim C. Brain opportunistic infections and tumors in people living with HIV - still a challenge in efficient antiretroviral therapy era. J Neurovirol 2023; 29:297-307. [PMID: 37219810 PMCID: PMC10204662 DOI: 10.1007/s13365-023-01135-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Revised: 03/23/2023] [Accepted: 04/07/2023] [Indexed: 05/24/2023]
Abstract
The aim of the study was to evaluate the incidence of brain opportunistic pathologies and survival in patients living with HIV from a Romanian tertiary center. A 15-year prospective observational study of brain opportunistic infections diagnosed in HIV-infected patients was performed at Victor Babes Hospital, Bucharest, between January 2006 and December 2021. Characteristics and survival were compared related to modes of HIV acquisition and type of opportunistic infection. A total of 320 patients were diagnosed with 342 brain opportunistic infections (incidence 9.79 per 1000 person-years), 60.2% males with median age at diagnosis of 31 years (IQR 25, 40). Median CD4 cell count and VL were 36/μL (IQR 14, 96) and 5.1 log10 copies/mL (IQR 4, 5.7) respectively. The routes of HIV acquisition were heterosexual (52.6%), parenteral route in early childhood (31.6%), injecting drug use (12.9%), men having sex with men (1.8%), and vertical (1.2%). The most common brain infections were progressive multifocal leukoencephalopathy (31.3%), cerebral toxoplasmosis (26.9%), tuberculous meningitis (19.3%), and cryptococcal meningitis (16.7%). Patients infected by parenteral mode in early childhood were younger at diagnosis of both opportunistic infection and HIV (p < 0.001 and p < 0.001, respectively), developed more frequently PML (p < 0.001), and had the lowest early (p = 0.002) and late (p = 0.019) mortality rates. Risk factors for shorter survival were age > 30 years (p = 0.001), injecting drug use (p = 0.003), CD4 + < 100/μL (p = 0.007), and VL > 5 log10 copies/mL at diagnosis (p < 0.001). The incidence and mortality rate of brain opportunistic infections were high and did not decrease significantly during the study period, due to late presentation or non-adherence to ART.

Abstract
Human immunodeficiency virus infection is related with an increased risk of hematological malignancy principally, non-Hodgkin lymphoma. Most non-Hodgkin lymphomas are acquired immunodeficiency syndrome defining and constitute greater than 50% of all acquired immunodeficiency syndrome defining cancers. The main pathogenesis mechanisms are immunodeficiency, chronic antigenic stimulation, and the ability to infect cancer cells causing direct carcinogenesis. Human immunodeficiency virus related non-Hodgkin lymphomas are heterogeneous in immunophenotyping and molecular features; and choice of drug treatments is similar with sporadic types. The main objective is to assess the epidemiology, pathogenesis, and morphology of human immunodeficiency virus related non-Hodgkin lymphoma. The searching strategy was done by searching relevant original and review articles from www.biosemanticjane/org, Google scholar, Google, and PubMed sites using keywords like; Acquired immunodeficiency syndrome, Human immunodeficiency virus, and non-Hodgkin lymphoma. In conclusion, human immunodeficiency virus infected people continue to have elevated risk of non-Hodgkin lymphoma. Diffuse large B-cell lymphomas are the most common and severe subtype. The pathogenesis of this type of lymphoma is associated with chromosomal abnormalities that deregulate the expression of various oncogenes by different viral particles and cytokines. However, the role of these viral particles and cytokines on pathogenesis is not clearly stated, so further study could be required.

Biomed Pharmacother 2021; 145:112392. [PMID: 34781140 DOI: 10.1016/j.biopha.2021.112392] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2021] [Revised: 10/21/2021] [Accepted: 11/02/2021] [Indexed: 12/24/2022] Open
Abstract
Polymerase chain reaction (PCR) analysis of Epstein-Barr virus (EBV) DNA in cerebrospinal fluid (CSF) remains vital for evaluating active EBV infection involving the central nervous system (CNS). CSF EBV DNA was often found in conjunction with other microbial infection affecting the CNS among patients infected with human immunodeficiency virus (HIV). Sometimes CSF EBV DNA is detectable in patients without neurological symptoms. This review focused on the clinical and laboratory features of CNS EBV infection among patients with HIV, and discussed various types of EBV-associated CNS infections, and predominant neoplasms involving CNS such as primary central nervous system lymphoma (PCNSL), CNS-non-Hodgkin's lymphoma, smooth muscle tumors and leiomyosarcomas, EBV encephalitis or myelitis, EBV meningitis and EBV coinfection with other causative agents were also included. Furthermore, the metagenomic next-generation sequencing technique with high sensitivity for the detection of pathogenic coinfection in the CSF were also reviewed. We concluded that CSF EBV-DNA detection with high sensitivity and specificity could be a useful diagnostic tool for CNS lymphoma among HIV patients; however, it is still unknown for other CNS diseases. We further summarized and conclude that positive CSF EBV-DNA detection combined with specific brain focal lesions could be a minimally invasive method to diagnose PCNSL. The occurrence of positive CSF EBV-DNA was influenced by PCR detection limit, PCR methods, immunocompromised status, the possible influence of anti-herpetic therapy and anti-HIV therapy, and the size and location of a tumor mass. Uniform PCR methods as vital diagnostic tools and optimal EBV-DNA load threshold need to be established.

Abstract
Primary central nervous system lymphoma of T-cell origin (T-PCNSL) is rare, and its clinicopathological features remain unclear. Peripheral T-cell lymphoma of γδ T-cell origin is an aggressive lymphoma mainly involving extranodal sites. Here, we report a case of γδ T-PCNSL involving the intramedullary spinal cord and presenting with paraplegia. A 75-year-old Korean woman visited the hospital complaining of back pain and lower extremity weakness. Magnetic resonance imaging revealed multifocal enhancing intramedullary nodular lesions in the thoracic and lumbar spinal cord. An enhancing nodular lesion was observed in the periventricular white matter of the lateral ventricle in the brain. There were no other abnormalities in systemic organs or skin. Laminectomy and tumor removal were performed. The tumor consisted of monomorphic, medium-to-large atypical lymphocytes with pale-to-eosinophilic cytoplasm. Immunohistochemically, the tumor cells were CD3(+), TCRβF1(-), TCRγ(+), CD30(-), CD4(-), CD8(-), CD56(+), TIA1(+), granzyme B(+), and CD103(+). Epstein-Barr virus in situ was negative. This case represents a unique T-PCNSL of γδ T-cell origin involving the spinal cord.

Abstract
The CD7 antigen is a member of the immunoglobulin superfamily that expresses on the surface of all thymocytes, a majority of mature T cells, and also natural killer cells. Interestingly, under physiological and different pathological conditions, the loss of CD7 antigen occurred in the subset of CD4+ memory T cells. Various functions have been proposed for CD7, including its role in the activation and intercellular adhesiveness of T cells. Several studies indicate that the number of CD4+ CD7- T cells increases in diseases such as chronic inflammation and T-cell malignancies, these being skin inflammatory lesions. Therefore, this can be useful for the diagnosis of cancer cells, especially with reference to blood origin, treatment monitoring, and establishment of new therapies. Therefore, a comprehensive review could be useful to increase our knowledge about the clinical importance of these cells in human disease.

FEBS J 2017; 284:2410-2424.

Abstract
Myeloid-derived suppressor cells (MDSCs), including granulocytic (G)-MDSCs and monocytic (M)-MDSCs, play a critical role in tumor-induced T cell tolerance. MDSC immunosuppressive function and differentiation are significantly promoted in patients and B-cell lymphoma model mice. However, the mechanisms regulating these processes remain largely unclear. In the present study, we observed increased microRNA (miR)-30a expression both in G-MDSCs and in M-MDSCs from B cell lymphoma model mice. After transfection with miR-30a mimics, the differentiation and suppressive capacities of MDSCs were significantly increased via up-regulation of arginase-1. Moreover, we showed that the 3'-UTR of suppressor of cytokine signaling 3 (SOCS3) mRNA is a direct target of miR-30a. Decreased SOCS3 expression and activated Janus kinase-signal transducer and activator of transcription 3 signaling promote MDSC differentiation and suppressive activities. These findings provide new insights into the molecular mechanisms underlying MDSC expansion and function during B cell lymphoma development.

Abstract
This study was to investigate the differences of lymphocyte in the cerebrospinal fluid (CSF) of patients with syphilis meningitis (SM) and tuberculous meningitis (TBM) for new diagnostic insights. Totally, 79 cases of SM and 45 cases of TBM were enrolled. In the CSF, the CD4, CD45RO or CD20 positive lymphocytes were detected by immunohistochemistry. The proportion of CD4 T cells in the CSF lymphocytes in patients with SM was significantly higher than that in patients with TBM (p < 0.05). After medical therapy, there was a significantly decline trend of the CD4 T-cell proportion in both groups (p < 0.05). The proportion of CD45RO T cells in CSF lymphocytes of patients with SM was less than that of patients with TBM (p < 0.05). After medical therapy, the positive ratio of CD45RO T cells was increased in the CSF of both group patients (p < 0.05). The proportion of CD20B cells in the CSF lymphocytes was not obviously different between the two groups during every stage. In conclusion, there are strong differences of CD4 and CD45RO T-cell ratio, but not the CD20 B cells in the meningitis. CD4 and CD45RO T cells in CSF are a useful complement in differentially diagnosing SM and TBM; it contributes to further understand the pathogenesis and prognosis of SM and TBM.
