It seems to be associated with nutritional status in the general population, but little is known about kidney transplant recipients (KTRs). This study aimed to explore the relationship between dietary balance index and serum Cys in KTRs. MATERIAL AND METHODS In a cross-sectional study, 215 KTRs completed an FFQ questionnaire and information on serum Cys. Dietary intake was assessed using the Food Frequency Questionnaire (FFQ). Dietary Balance Index 2016 (DBI-16) edition scores were calculated as an indicator of dietary quality. Data on the patient's serum Cys were obtained through the hospital information system. RESULTS The majority of KTRs were male (75.34%), 76.74% were aged 18-44 years, and 79.53% were abnormal serum Cys. Dairy (z=-2.161, P<0.05), meat (z=-2.578, P<0.05), and dietary diversity (z=-3.393, P<0.05) in the normal group were higher than those in the abnormal group, and the dietary quality distance (DQD) score (t=-2.264, P<0.05) was lower than that in the abnormal group. After adjusting for confounders, a low-quality diet was a risk factor for maintaining the normal level of serum Cys (OR 3.022, 95% CI 1.263-7.231, P<0.05). CONCLUSIONS The present study suggested that KTRs with a high dietary quality might be associated with normal serum Cys levels. Dairy, meat, and varied diet seems to impact the serum Cys levels of KTRs.

GVHD diagnosis is usually based on clinical symptoms and pathologic confirmation. However, it is often misdiagnosed due to its non-specific symptoms. Here, we report the detection of donor-cell chimerism using peripheral blood (PB) donor-derived deoxyribonucleic acid (ddDNA) for 3 cases with suspected GVHD after LT (GVHD-LT) through real-time quantitative polymerase chain reaction (qPCR) assay targeting 39 insertions and/or deletions of chromosomes. MATERIAL AND METHODS The qPCR assay for detecting donor-cell chimerism was performed for 3 post-LT patients with suspected GVHD using KMRtype® and KMRtrack® assays (GenDx, Netherlands). The mean recipient/donor-cell fraction of informative markers unique to each recipient or donor was calculated. RESULTS In Case 1, who received living donor LT (LDLT) from his daughter, initial sign was diarrhea at post-operative day (POD) #23. Case 2 received unrelated deceased donor LT and initial sign was cytopenia at POD #29. Case 3 received LDLT from her son and GVHD associated cytopenia was developed at POD #80. Average PB ddDNA fractions in post-transplant samples of cases 1, 2, and 3 were 39.68%, 78.38%, and 4.76%, respectively. Despite an active treatment including steroid and tumor necrosis factor-alpha inhibitor, 2 patients (cases 1 and 2) died due to multiple organ failures.

MATERIAL AND METHODS Medical data of multiple myeloma or lymphoma patients who underwent autologous non-cryopreserved HSCT were reviewed. RESULTS A total of 58 patients (40 myeloma and 18 lymphoma) were reviewed. The median myeloma and lymphoma CD34⁺ cell doses were 7.59 and 6.9 million/kg, respectively, with good viability after storage.

MATERIAL AND METHODS After propensity score matching, we compared 71 kidney recipients with biopsy-proven acute rejection with 71 patients without rejection and also subjects with different histologic types of rejection. All 3 types of blood cell count-derived ratios were calculated 6 and 3 days prior to biopsy and on the day of biopsy. RESULTS There were 15 patients with T cell-mediated rejection, 33 with vascular rejection, and 23 with antibody-mediated rejection. The values of all examined ratios did not differ between subgroups with and without rejection. However, at all post-transplant study time-points, patients with antibody-mediated rejection had significantly higher values of all analyzed ratios than subjects with other types of rejection.
