Lactic acid bacteria are known to have various effects on the immune system. The type and extent of the effect differ, depending on the type of lactic acid bacteria. This study aimed to investigate the effects of Lactobacillus johnsonii bacterin on mouse-derived immune cells. Treating splenocytes with L. johnsonii bacterin slightly increased the metabolic activity. Additionally, the expression of the activation marker CD25 and production of the Th1-type inflammatory cytokine interferon (IFN)-gamma increased. We confirmed that the increase in IFN-gamma production due to L. johnsonii stimulation was mainly due to T and B cells among splenocytes. Treating dendritic cells (DCs) with L. johnsonii bacterin at concentrations of 10 6 and 10 7 cfu/ ml significantly increased tumor necrosis factor-alpha, a pro-inflammatory cytokine, and interleukin-12, a cell-mediated immunity cytokine. Additionally, the expression of surface markers increased. Allogeneic mixed lymphocyte reactions showed that L. johnsonii reduced the antigen-presenting ability of DCs. In cocultures of DCs and splenocytes, L. johnsonii decreased cellular metabolic activity and increased cell death. L. johnsonii upregulated the expression of programmed death ligand 1 on DCs. The findings of this study indicate that L. johnsonii bacterin has immunomodulatory and immunostimulatory effects. While L. johnsonii increased the expression of cytokines and surface markers of immune cells, it modulated DC-mediated immune response. Further studies are needed to determine the effects of L. johnsonii bacterin on DCs and related immune cells.

Background/Aims: This study aimed to evaluate the performance of the Model for End-Stage Liver Disease (MELD) 3.0 for predicting mortality and liver-related complications compared with the Child-Pugh classification, albumin-bilirubin (ALBI) grade, the MELD, and the MELD sodium (MELDNa) score. Methods: We evaluated a multicenter retrospective cohort of incorporated patients with cirrhosis between 2013 and 2019. We conducted comparisons of the area under the receiver operating characteristic curve (AUROC) of the MELD3.0 and other models for predicting 3-month mortality. Additionally, we assessed the risk of cirrhosis-related complications according to the MELD3.0 score. Results: A total of 3,314 patients were included. The mean age was 55.9±11.3 years, and 70.2% of the patients were male. Within the initial 3 months, 220 patients (6.6%) died, and the MELD3.0had the best predictive performance among the tested models, with an AUROC of 0.851, outperforming the Child-Pugh classification, ALBI grade, MELD, and MELDNa. A high MELD3.0score was associated with an increased risk of mortality. Compared with that of the group with a MELD3.0 score <10 points, the adjusted hazard ratio of the group with a score of 10–20 pointswas 2.176, and that for the group with a score of ≥20 points was 4.892. Each 1-point increase inthe MELD3.0 score increased the risk of cirrhosis-related complications by 1.033-fold. The risk of hepatorenal syndrome showed the highest increase, with an adjusted hazard ratio of 1.149, followed by hepatic encephalopathy and ascites. Conclusions The MELD3.0 demonstrated robust prognostic performance in predicting mortality in patients with cirrhosis. Moreover, the MELD3.0 score was linked to cirrhosis-related complications, particularly those involving kidney function, such as hepatorenal syndrome and ascites.

Purpose: To evaluate the efficacy and toxicities of skin-directed radiotherapy (RT) in primary cutaneous T-cell lymphoma (CTCL). Materials and Methods: We retrospectively analyzed 57 CTCL lesions treated with skin-directed RT between January 2000 and December 2022. Lesions were categorized into three distinct groups: early-stage disease treated with local RT, advanced-stage disease treated with local RT, and advanced-stage disease treated with total skin electron beam therapy (TSEBT). Treatment outcomes, including response rates, recurrence patterns, and local progression probability, were assessed for each group. Results: Mycosis fungoides (MF) constituted 90.9% of the advanced-stage pathologies, while CD4+ primary cutaneous small/medium T-cell lymphoproliferative disorder was common in the early stage lesions (55%). Median RT doses were 30.6 Gy, 27 Gy, and 32 Gy for the local RT with early stage, the local RT with advanced stage, and TSEBT with advanced stage, respectively. The complete response rates were high across the groups: 95.5%, 70.8%, and 90.9%, respectively. Seven local recurrences (29.2%) occurred in the local RT group with advanced stage, while seven patients (63.6%) in the TSEBT group experienced local failure. All recurrences were observed in lesions and patients with MF. Acute toxicities were mainly grade 1 or 2, with no grade 3 or higher events. No significant association between RT dose and local progression rates in MF lesions was found. Conclusion Skin-directed RT in CTCL is effective for local control and well-tolerated with less toxicity.
