Summary: The study found that CMV infection following allo-HSCT correlated with increased mortality in children's patients, and haplo-HSCT was identified as an independent risk factor for CMV infection. Adoptive CMV-CTL cell therapy was safe and effective in pediatric patients with CMV infection.

Summary: Untreated HIV-1 infection leads to a decrease in CD4(+) T cell lymphocytes, susceptibility to opportunistic infections, and ultimately death. This study found that cytotoxic lymphocytes can target the HIV-1 Gag protein through granzyme cleavage to potentially control HIV-1 infection.

Summary: This study reveals a potential association between the non-pathogenic HPgV-1 virus and immunomodulation after allo-HSCT, suggesting that HPgV-1 may impair NK cell immune-reconstitution. This provides initial evidence for the potential impact of HPgV-1 infection.

Summary: Until recently, available drugs for CMV prevention and treatment in transplant patients have been limited by toxicity and resistance issues, with letermovir being the first new drug approved for CMV prevention since 2003. The efficacy of letermovir in treating established CMV infection or disease remains largely unstudied, while the investigational agent maribavir shows promise as a preemptive treatment option with unique mechanisms of action. Ongoing studies will define the efficacy of these drugs in patients with refractory or resistant CMV disease.

Summary: Cytomegalovirus (CMV) is a common infection in immunocompromised patients, especially those undergoing allo-HSCT. Recent management strategies include pre-emptive treatment with frequent CMV PCR monitoring and the use of new drugs like letermovir. Treatment of CMV disease is challenging due to drug resistance, but promising results have been seen with maribavir and other alternative treatments such as immunotherapy, artesunate, and leflunomide.

Summary: The expression of cytotoxic molecules in feline intestinal T-cell lymphoma cells, particularly their infiltration in the mucosal epithelium, is associated with shorter survival times.

Summary: This study analyzed the association between CMV reactivation and survival outcomes in patients undergoing auto-SCT and developed a predictive model for late CMV reactivation. The study found that early CMV reactivation was significantly associated with better overall survival in multiple myeloma patients, while late CMV reactivation, high lactate dehydrogenase level, and lymphoma diagnosis were independent risk factors for poor overall survival. The predictive risk model showed good discrimination in identifying high-risk patients for late CMV reactivation.

Summary: This study aimed to determine the relationship between CMV infection/serostatus and IFIs in allo-HSCT populations. The results showed that post-transplant CMV infection and high-risk CMV serostatus increased the risk of IFIs, while low-risk CMV serostatus decreased the risk of IFIs.

Summary: CMV infection is a common and severe complication of allo-HSCT in Taiwan due to high CMV seropositivity in the population. A CMV management strategy focusing on monitoring, prophylaxis, and treatment is proposed, including weekly monitoring with the COBAS (R) AmpliPrep system, a 14-week prophylactic course of letermovir for allo-HSCT recipients, and preemptive ganciclovir therapy when CMV viral load exceeds 1000 copies/mL. Limited availability of foscarnet is a crucial issue for patients not responsive to ganciclovir in Taiwan.

Summary: The study retrospectively analyzed a cohort of patients who underwent HSCT and found that CMV clinically significant infection (CS-CMVi) occurred in 48% of prophylactically treated patients, but it did not impact relapse incidence or overall survival. Additionally, the use of CMV-IG alone as prophylactic therapy did not effectively prevent CMV reactivation.

Summary: The immune system of patients with active Multiple Myeloma is significantly modulated by therapy, with treatments such as autologous stem cell transplantation and Lenalidomide leading to a dominant cytotoxic response that contributes to the anti-Myeloma effect of these regimens.

Summary: After conducting the study, it was found that the clinical manifestations of CMV retinitis differed between the SOT and HSCT groups, with different poor prognostic factors associated with each. The presence of concurrent CMV disease and foveal involvement were identified as factors associated with poor visual outcomes in CMV retinitis following transplantation in both the SOT and HSCT groups.

Summary: Reactivation of both cytomegalovirus and Epstein-Barr virus is common after hematopoietic stem cell transplantation and is associated with poor outcomes, including lower overall survival and leukemia-free survival rates. Co-reactivation of these viruses is also linked to prolonged viral duration and poor CD4+CD25+ T cell reconstitution post-transplantation.

Summary: CD4(+)FOXP3(+) regulatory T cells (Tregs) have been shown to be effective in preventing and treating graft-versus-host disease (GVHD). This study provides insight into the mechanisms by which Tregs suppress acute GVHD, demonstrating that they primarily affect the transcription of CD4 T cells and modulate the expression of genes involved in inflammation and metabolism. These findings support the clinical translation of Tregs as an immunoregulatory approach for GVHD.
