AI Article Synopsis

  • The study investigates SOCS gene expression in relation to CMV viremia after hematopoietic stem cell transplantation.
  • It compares SOCS1 and SOCS3 levels in healthy donors, pre-HSCT patients, and HSCT recipients categorized by CMV viremia and acute graft-versus-host disease (aGVHD).
  • Findings indicate that SOCS1 expression increases in CMV positive subgroups, particularly with aGVHD, while SOCS3 expression decreases across all groups, suggesting a link between SOCS regulation and CMV viremia.

Article Abstract

Background: The expression of the SOCS genes in cytomegalovirus (CMV) viremia after hematopoietic stem cell transplantation (HSCT) remains largely unexplored.

Methods: Using quantitative RT-PCR of mononuclear cells, we conducted pairwise comparison of SOCS1 and SOCS3 expression levels among a healthy donor group (N=55), a pre-HSCT group (N=17), and the recipient subgroup (N=107), which were divided according to the occurrence of CMV viremia and acute graft-versus-host disease (aGVHD).

Results: Compared to that in the healthy donor group, SOCS1 expression was higher in the CMV+ subgroup, especially in the CMV+GVHD- group, but decreased in the other subgroups. When compared to the expression in the pre-HSCT group, SOCS1 expression was significantly higher in the CMV+ subgroup, especially in the CMV+GVHD+ subgroup. Meanwhile, compared to that in the healthy donor group, SOCS3 expression was significantly lower in all other groups. The CMV-GVHD- subgroup showed significantly lower SOCS3 expression compared to the CMV+ subgroup, the CMV+GVHD+ subgroup, and the CMV+GVHD- subgroup.

Conclusion: We report differential expression of SOCS genes according to CMV viremia with acute GVHD occurrence after HSCT, suggesting that regulation of SOCS expression is associated with CMV viremia.

Background: In vivo T-cell depletion with antithymocyte globulin (ATG), especially at high-doses has been shown to be associated with increased incidence of infections after allogeneic hematopoietic stem cell transplantation (HSCT). However, it remains unclear whether ATG, even at low-doses increases the risk of posttransplant infections in the high-risk HSCT setting.

Patients And Methods: We conducted a single-center retrospective study of viral and fungal infections early after transplantation, using the data from 82 patients with hematological malignancies.

Cytomegalovirus infections and reactivations are more frequent in people living with HIV (PLWH) and have been associated with increased risk of HIV progression and immunosenescence. We explored the impact of combination antiretroviral therapy (cART) on latent CMV infection in 225 young adults parenterally infected with HIV during childhood. Anti-CMV IgG antibodies were present in 93.

Introduction: In renal transplantation, donor hepatitis C virus (HCV) status is crucial to consider when selecting a recipient given the high likelihood of transmission. We analyzed the effect of donor HCV status on post-renal transplant rejection and virologic infectious outcomes using electronic health record data from multiple US health care organizations.

Methods: Using real world data from electronic health records of renal transplant recipients, a propensity score-matched case-control study of one-year renal transplant outcomes was conducted on cohorts of HCV-negative recipients who received an organ from an HCV-positive donor (HCV D+/R-) versus from an HCV-negative donor (HCV D-/R-).

Treating acute rejection of a pancreas transplant in a severely immunocompromised patient with viral opportunistic infection is challenging due to the balance of rescuing from rejection without worsening the morbidity of infection and prolonging the infection episode. We present a case involving a pancreas-after-kidney transplant in a patient with CMV high-risk discordance (donor positive/recipient negative) and chronic lymphopenia who developed difficult-to-treat CMV disease approximately six months after pancreas transplant. Following the withdrawal of the antimetabolite due to the persistent CMV DNAemia and lymphopenia, the patient experienced acute pancreas rejection without adequate and sustained response to treatment with steroids and Thymoglobulin.

Background: Cytomegalovirus (CMV) is a significant cause of morbidity and death in solid organ transplant recipients. Pre-emptive treatment of patients with CMV viraemia using antiviral agents has been suggested as an alternative to routine prophylaxis to prevent CMV disease. This is an update of a Cochrane review first published in 2006 and updated in 2013.
