    Abstract Background: Although the number of times dialyzer-reuse in hemodialysis is currently determined by the total volume of the dialyzer, the determination by macrophage activation using dialyzer-eluted protein might predict systemic inflammation.
    Objective: The pro-inflammatory activities of the proteins from 5- and 15-times reused dialyzers were tested as a proof of concept experiment.
    Methods: Accumulated proteins in dialyzers were eluted by the roller pump (the recirculation of 100 mL of buffer in a dialyzer with a roller pump at 15 mL/min for 2 h) or infusion procedures (infusion of 100 mL buffer in a dialyzer for 2 h) using chaotropic or potassium phosphate buffers (KPB) before the activation on macrophages cell lines (THP-1-derived human macrophages or RAW264.7 murine macrophages).
    Results: The concentrations of dialyzer-eluted protein from both methods were not different and the infusion procedure was further used. The eluted proteins (by both buffers) from 15-times-reused dialyzers reduced cell viability, increased supernatant cytokines (TNF-α and IL-6), and upregulated pro-inflammatory genes (IL-1β and iNOS) in either THP-1-derived or RAW264.7 macrophages (higher responses in RAW264.7 cells) compared with the new dialyzer. Meanwhile, the 5-times-reused dialyzer protein did not reduce cell viability but enhanced some of these pro-inflammatory macrophage markers.
    Conclusions: Due to the simpler preparation of KPB over chaotropic buffer with an easier protocol of RAW264.7 over THP-1-derived macrophages, the responses of RAW264.7 against dialyzer-eluted protein with infusion method using KPB buffer were proposed for determination of the number of times dialyzer reuse in hemodialysis.

    Abstract Although current regimens of immunosuppressive drugs are effective in renal transplant recipients, long-term renal allograft outcomes remain suboptimal. For many years, the diagnosis of renal allograft rejection and of several causes of renal allograft dysfunction, such as chronic subclinical inflammation and infection, was mostly based on renal allograft biopsy, which is not only invasive but also possibly performed too late for proper management. In addition, certain allograft dysfunctions are difficult to differentiate from renal histology due to their similar pathogenesis and immune responses. As such, non-invasive assays and biomarkers may be more beneficial than conventional renal biopsy for enhancing graft survival and optimizing immunosuppressive drug regimens during long-term care. This paper discusses recent biomarker candidates, including donor-derived cell-free DNA, transcriptomics, microRNAs, exosomes (or other extracellular vesicles), urine chemokines, and nucleosomes, that show high potential for clinical use in determining the prognosis of long-term outcomes of kidney transplantation, along with their limitations.

    Abstract Although macrophage depletion is a possible emerging therapeutic strategy for osteoporosis and melanoma, the lack of macrophage functions can lead to inappropriate microbial control, especially the regulation of intestinal microbiota. Cecal ligation and puncture (CLP) sepsis was performed in regular mice and in mice with clodronate-induced macrophage depletion. Macrophage depletion significantly increased the mortality and severity of sepsis-CLP mice, partly through the increased fecal Ascomycota, especially

    Abstract Background: Although allergy might be another factor that exacerbates lupus as demonstrated by several epidemiologic studies, the direct correlation between lupus activities and allergy is still in question.
    Objective: To explore the correlation between allergic reaction and lupus activities.
    Methods: The allergic asthma model using ovalbumin (OVA) administration in wildtype (WT) and Fc gamma receptor IIb deficient (FcgRIIb-/-) mice (a lupus-prone model) together with in vitro experiments on bone marrow-derived dendritic cells (DCs) were performed.
    Results: At 2-weeks-post OVA, both WT and FcgRIIb-/- mice demonstrated similar allergic reaction as indicated by an elevation of IgE and IL-4 in serum with asthma-liked lung histology (lung weight, inflammatory score, and bronchial thickness) with increased spleen weight. Apoptosis in the lungs and spleens (activated caspase 3 immunohistochemistry) was detected only in OVA-administered FcgRIIb-/- mice. Surprisingly, OVA-administered FcgRIIb-/- mice, demonstrated active lupus nephritis, as indicated by anti-dsDNA, proteinuria, and renal immune complex deposition (immunohistochemistry analysis) implying an impact of allergy on lupus activities. Meanwhile, serum creatinine and gut permeability defect (FitC-dextran assay and endotoxemia) were not different between the FcgRIIb-/- mice with OVA versus with control. In parallel, FcgRIIb-/- DCs were more susceptible to activations by OVA and lipopolysaccharide (LPS) than WT DCs as demonstrated by CD80 with major histocompatibility complex II (MHC II) using flow cytometry analysis.
    Conclusion: OVA-induced allergy in FcgRIIb-/- mice exacerbated lupus activity, possibly due to hyper-responsiveness of FcgRIIb-/- DCs over WT from the loss of inhibitory FcgRIIb. The proper control of allergy might be beneficial for lupus.

    Abstract Background: Evidence has demonstrated inferior humoral immune responses after SARS-CoV-2 vaccination in kidney transplant recipients compared to the general population. However, data on cellular immune responses in this population have not been established.
    Methods: We searched the MEDLINE, Scopus, and Cochrane databases and included studies reporting cellular immune response rates in kidney transplant recipients after receiving SARS-CoV-2 vaccines. Studies that reported factors associated with cellular immune responders or non-responders were also included (PROSPERO: CRD42022375544).
    Results: From a total of 1,494 articles searched, 53 articles were included in the meta-analysis. In all, 21 studies assessed cellular immune response by interferon-γ enzyme-linked immunosorbent spot (IFN-γ ELISPOT), 22 studies used interferon-γ release assay (IGRA), and 10 studies used flow cytometric analysis. The pooled response rate after two doses (standard regimen) and three doses of vaccination was 47.5% (95%CI 38.4-56.7%) and 69.1% (95%CI 56.3-80.6%) from IFN-γ ELISPOT, 25.8% (95%CI 19.7-32.4%) and 14.7% (95%CI 8.5-22.2%) from IGRA, and 73.7% (95%CI 55.2-88.8%) and 86.5% (95%CI 75.3-94.9%) from flow cytometry, respectively. Recipients with seroconversion were associated with a higher chance of having cellular immune response (OR 2.58; 95%CI 1.89-3.54). Cellular immune response in kidney transplant recipients was lower than in dialysis patients (OR 0.24; 95%CI 0.16-0.34) and the general population (OR 0.10; 95%CI 0.07-0.14). Age and immunosuppressants containing tacrolimus or corticosteroid were associated with inferior cellular immune response.
    Conclusion: Cellular immune response after SARS-CoV-2 vaccination in kidney transplant recipients was lower than in dialysis patients and the general population. Age, tacrolimus, and corticosteroid were associated with poor response. Cellular immune response should also be prioritized in vaccination studies.

    Abstract Both a leaky gut (a barrier defect of the intestinal surface) and gut dysbiosis (a change in the intestinal microbial population) are intrinsic to sepsis. While sepsis itself can cause dysbiosis, dysbiosis can worsen sepsis. The leaky gut syndrome refers to a status with which there is an increased intestinal permeability allowing the translocation of microbial molecules from the gut into the blood circulation. It is not just a symptom of gastrointestinal involvement, but also an underlying cause that develops independently, and its presence could be recognized by the detection, in blood, of lipopolysaccharides and (1→3)-β-D-glucan (major components of gut microbiota). Gut-dysbiosis is the consequence of a reduction in some bacterial species in the gut microbiome, as a consequence of intestinal mucosal immunity defect, caused by intestinal hypoperfusion, immune cell apoptosis, and a variety of enteric neuro-humoral-immunity responses. A reduction in bacteria that produce short-chain fatty acids could change the intestinal barriers, leading to the translocation of pathogen molecules, into the circulation where it causes systemic inflammation. Even gut fungi might be increased in human patients with sepsis, even though this has not been consistently observed in murine models of sepsis, probably because of the longer duration of sepsis and also antibiotic use in patients. The gut virobiome that partly consists of bacteriophages is also detectable in gut contents that might be different between sepsis and normal hosts. These alterations of gut dysbiosis altogether could be an interesting target for sepsis adjuvant therapies, e.g., by faecal transplantation or probiotic therapy. Here, current information on leaky gut and gut dysbiosis along with the potential biomarkers, new treatment strategies, and future research topics are mentioned.

    Abstract Background: Vitamin C is a potent scavenger of reactive oxygen species, which induce neutrophil extracellular trap (NET) formation. NETs are a major source of autoantigens and are involved in systemic lupus erythematosus (SLE) pathogenesis. We determined vitamin C status and evaluated NET formation and inflammatory cytokines in children with lupus nephritis.
    Methods: Serum vitamin C was measured in 46 patients (82.6% females, mean age 14.5 ± 0.3 years). Vitamin C levels < 0.3 mg/dL indicated vitamin C deficiency. Patients were divided into two groups according to serum vitamin C levels: normal and low (< 0.3 mg/dL). We compared NET formation and levels of SLE-related cytokines, including interleukin (IL)-8, IL-10, and tumor necrosis factor-α (TNF-α), between groups. NET formation was determined through measurement of serum citrullinated histone 3 levels and mRNA expression of peptidyl arginine deiminase-4 and assessment of the percentage of neutrophils with NETs by immunofluorescence.
    Results: Nine patients (19.6%) had vitamin C deficiency. Kidney pathology assessment at disease onset revealed that histological activity index and number of kidney biopsies containing crescentic glomeruli were higher in vitamin C-deficient patients, but chronicity index was not. NET formation and serum IL-8 were more prominent in vitamin C-deficient patients. Serum IL-8 levels were 12.9 ± 5.2 pg/mL in low vitamin C group and 5.2 ± 0.9 pg/mL in normal vitamin C group (p = 0.03). Serum IL-10 and TNF-α were similar between groups.
    Conclusions: Our study demonstrated correlation among vitamin C deficiency, increased NET formation, and IL-8 upregulation in children with lupus nephritis. A prospective study is required to evaluate cause‒effect relationships of vitamin C status, NET formation and IL-8 expression.

    Abstract The gut barrier is a single cell layer that separates gut micro-organisms from the host, and gut permeability defects result in the translocation of microbial molecules from the gut into the blood. Despite the silent clinical manifestation, gut translocation of microbial molecules can induce systemic inflammation that might be an endogenous exacerbating factor of systemic lupus erythematosus. In contrast, circulatory immune-complex deposition and the effect of medications on the gut, an organ with an extremely large surface area, of patients with active lupus might cause gut translocation of microbial molecules, which worsens lupus severity. Likewise, the imbalance of gut microbiota may initiate lupus and/or interfere with gut integrity which results in microbial translocation and lupus exacerbation. Moreover, immune hyper-responsiveness of innate immune cells (macrophages and neutrophils) is demonstrated in a lupus model from the loss of inhibitory Fc gamma receptor IIb (FcgRIIb), which induces prominent responses through the cross-link between activating-FcgRs and innate immune receptors. The immune hyper-responsiveness can cause cell death, especially apoptosis and neutrophil extracellular traps (NETosis), which possibly exacerbates lupus, partly through the enhanced exposure of the self-antigens. Leaky gut monitoring and treatments (such as probiotics) might be beneficial in lupus. Here, we discuss the current information on leaky gut in lupus.
