FACTORS AFFECTING THE VARIATION OF TACROLIMUS LEVELS IN KIDNEY TRANSPLANT PATIENTS AT VIET DUC UNIVERSITY HOSPITAL

2025-09-04T07:53:18+00:00

Objectives: To analyze usage characteristics and Tacrolimus (TAC) trough level variability over time, and to analyze some factors affecting the intra-patient variability in TAC exposure in the first year after kidney transplantation. Methods: A retrospective, descriptive study was conducted based on medical records of patients who underwent kidney transplantation and had regular follow-up at the Department of Kidney Diseases and Dialysis, Viet Duc University Hospital, from January 1, 2019 to June 30, 2023. Results: 274 medical records of 274 kidney transplant patients were included. Dosage, trough concentrations, and intra-individual variability (IPV) of TAC trough concentrations tended to decrease over time. Logistic regression analysis revealed factors associated with high IPV (CV > 30%) in the first month after transplantation including concomitant use of azole antifungal agents non-continuously vs. continuously use vs. no use (OR = 16.51; p < 0.001); concomitant use of diltiazem non-continuously vs continuously use or no use (OR = 2.92; p = 0.002); factors during the 2 - 6 month period included hematocrit (OR = 0.86; p = 0.001) and mean C0/D ratio (OR = 1.41; p < 0.001); during the 6 - 12-month period, switching between twice-daily and once-daily formulations compared to no switching was associated (OR = 1.17; p = 0.004). Conclusion: TAC trough levels IPV decrease over time after transplantation. High IPV of TAC levels includes concomitant use of azole antifungal and diltiazem agents non-continuously; hematocrit and switching between twice-daily and once-daily formulations.

STUDY ON CHANGES IN LEFT VENTRICULAR STIFFNESS BY SPECKLE TRACKING ECHOCARDIOGRAPHY IN PATIENTS WITH END-STAGE CHRONIC KIDNEY DISEASE BEFORE AND AFTER KIDNEY TRANSPLANTATION

2025-09-08T07:39:47+00:00

Objectives: To investigate the change in left ventricular stiffness by speckle tracking echocardiography (STE) in patients with end-stage chronic kidney disease (ESKD) before and after kidney transplantation.Methods: A prospective, cross-sectional descriptive study was conducted on 63 patients with ESKD who underwent kidney transplantation at Military Hospital 103 from October 2024 to April 2025. All patients were followed up 1 month after transplantation. Results: There was no significant difference in DWS before and after kidney transplantation. Left ventricular stiffness after kidney transplantation decreased significantly compared to before transplantation. Left ventricular stiffness after transplantation in the hemodialysis group increased significantly compared to the emptive treatment group when assessed by both tissue doppler (TDI) and STE. There was no difference in DWS after transplantation between the two treatment groups. Left ventricular stiffness after transplantation in the hemodialysis group > 12 months was significantly higher than that < 12 months when assessed by both TDI and STE. Conclusion: 1 month after kidney transplantation, left ventricular stiffness measured by 3 methods (DWS and E/e’/LVEDV and E/LASr/LVEDV) tended to improve, reflecting a reduction in myocardial stiffness. Factors such as pre-transplant treatment and duration of dialysis may also affect left ventricular stiffness.

2025-09-03T08:52:25+00:00

Objectives:To investigate Tacrolimus's (TAC) concentration and intra-patient variability of Tacrolimus concentrations and analyze its relationship with some clinical and subclinical characteristics in patients after kidney transplantation from the 7th to the 12th month. Methods: A retrospective, prospective, cross-sectional descriptive study was conducted on 108 patients who were evaluated for the coefficient of variation of TAC concentration based on the quantification of TAC trough concentrations at the 7th to the 12th month post-kidney transplantation. The distribution of drug concentration variation was based on the quartile principle. Results: The median IPV of the study group from 7th to 12th month was 19.0%, with a minimum of 6.84% and a maximum of 57.84%. The proportion of patients with high IPV was 13.9%. IPV was not significantly associated with age, sex, eGFR, MMF dose, hemoglobin concentration, and post-transplant proteinuria, with p > 0.05. IPV was associated considerably with TAC trough concentrations at months 8, 9, and 10; p < 0.05. IPV was significantly related to TAC trough concentrations at months 8, 9, and 10; p < 0.05. Conclusion: The IPV of the study group during the 6 months (7th to 12th) fluctuated significantly and was significantly related to trough concentrations at months 8, 9, and 10.

2025-08-18T08:17:45+00:00

Objectives: To evaluate the quality of life (QoL) of kidney transplant recipients. Methods: A prospective, cross-sectional descriptive study was conducted on 172 kidney transplant recipients followed up at the Military Hospital 103. QoL was assessed using the SF-36 questionnaire. Results: The mean SF-36 score was 70.94 ± 15.32; the physical health component was 69.67 ± 17.51; and the mental health component was 72.21 ± 16.01. Overall, 48.8% of patients had SF-36 scores > 75, 39.5% scored 50 - 75, and 11.6% scored 25 - 50; no patients had scores < 25. Patients with BK, CMV, HBV, HCV infections, hypertension, diabetes, a history of acute rejection therapy, or elevated serum creatinine had significantly lower SF-36 scores (p < 0.05). No difference was observed between male and female patients (p > 0.05). Conclusion: Kidney transplant recipients achieved a fairly good QoL. Viral infections (BK, CMV, HBV, HCV), comorbid conditions (hypertension, diabetes), acute rejection, and reduced graft function were associated with decreased QoL.

INVESTIGATION OF THE ASSOCIATION BETWEEN INSULIN RESISTANCE AND SOME CHARACTERISTICS IN PATIENTS WITH NEW-ONSET DIABETES AFTER KIDNEY TRANSPLANTATION

2025-08-26T03:14:26+00:00

Objectives: To investigate insulin resistance status and its association with some characteristics in patients with new-onset diabetes after kidney transplantation (NODAT). Methods: A cross-sectional descriptive study was conducted on 81 patients with untreated NODAT and 53 age- and sex-matched healthy controls at Military Hospital 103 from October 2021 to December 2023. Clinical and laboratory characteristics were collected, and insulin resistance indices were calculated using the HOMA2 model, including insulin resistance (HOMA2-IR), insulin sensitivity (HOMA2-S), and β-cell function (HOMA2-B). Results: The median HOMA2-IR in the NODAT group was 0.95, which was significantly higher than that of the control group (0.7); p < 0.001. In contrast, both HOMA2-S and HOMA2-B were markedly reduced in the NODAT group compared to the control group (p < 0.001). Among NODAT patients, the prevalence of elevated HOMA2-IR, decreased HOMA2-S, and impaired HOMA2-B was 18.5%, 19.8%, and 27.2%, respectively. Patients with increased HOMA2-IR or reduced HOMA2-S exhibited significantly greater waist circumference, higher mean BMI, with those without these abnormalities, and the rate of increased HOMA2-IR was significant with OR 6,08 and 7,0, respectively (p < 0.05). Conclusion: Insulin resistance in NODAT patients is associated with increased waist circumference and higher BMI,

2025-08-29T00:31:59+00:00

Objectives: To evaluate the prevalence of anemia during the first six months after kidney transplantation and its association with selected clinical and paraclinical characteristics in patients undergoing kidney transplantation. Methods: A combined retrospective and prospective study was conducted on 258 patients who successfully underwent kidney transplantation between January 2022 and January 2025 at Military Hospital 103. Anemia prevalence was assessed at 1 week, 1 month, 3 months, and 6 months post-transplant. Results: The prevalence of anemia progressively decreased from 92.24% at 1 week to 68.6% at 1 month, 39.53% at 3 months, and 23.26% at 6 months. Most cases were mild normocytic normochromic anemia; polycythemia was observed in 5.04% of patients. At 6 months post-transplant, female patients and those with an estimated glomerular filtration rate (eGFR) < 60 mL/min had significantly lower hemoglobin levels compared with other groups (p < 0.05). Patients’ age and post-transplant eGFR were independent predictors of anemia, with odds ratios of 0.97 and 0.96, respectively (p < 0.05). Conclusion: Anemia was highly prevalent during the first six months after kidney transplantation, although the prevalence decreased over time. At 6 months, anemia persisted in 23.26% of patients and was associated with female sex, reduced eGFR, and older age.

2025-08-14T07:50:31+00:00

Objectives: To survey tissue-organ donation activities from brain death or circulatory death at Cho Ray Hospital from June 2024 to July 2025. Methods: A retrospective study on the allocation activities of tissue-organ donation and transplantation was conducted from June 2014 - July 2025. The activities consist of three separate branches with closely coordinated processes: The donor management branch, the patient on the waitlist management branch, and the media branch. Results: The allocation activities of tissue-organ donation and transplantation at Cho Ray Hospital achieved the following results: The donor management branch received 42 donors. The patient on the waitlist management branch received 183 patients. The media branch includes many articles to popularize knowledge about tissue-organ donation and transplantation. Conclusion: To develop the tissue-organ donation and transplantation program from brain-death or circulatory death that ensures transparency and fairness, the coordination system must have a clinical pathway, a strict and clear coordination process between specialties to ensure the scientific integrity and compliace with the ethics and law.

EMERGENCY LIVER TRANSPLANTATION IN A PATIENT WITH HEPATITIS B VIRUS-RELATED CIRRHOSIS COMPLICATED BY HEPATORENAL SYNDROME: A CLINICAL CASE REPORT

2025-09-03T08:49:52+00:00

Objectives: To present a clinical case of hepatitis B virus-related (HBV) cirrhosis that developed hepatorenal syndrome - acute kidney injury (HRS-AKI), managed with hemodialysis, plasma exchange, and subsequent liver transplantation; and to discuss diagnostic challenges, therapeutic strategies, and renal function recovery after transplantation. Methods: A case report was conducted on a patient with HRS-AKI who underwent emergency liver transplantation. Results: A 41-year-old male with cirrhosis due to chronic HBV infection, with poor treatment adherence, was admitted in a state of altered consciousness, ascites, and oliguria. Laboratory findings revealed severe progressive hepatic dysfunction and renal impairment. The patient was diagnosed with HRS-AKI after exclusion of other causes of acute kidney injury. Vasoconstrictor therapy and albumin infusion were unsuccessful, necessitating continuous renal replacement therapy and plasma exchange. Emergency liver transplantation was performed 10 days after admission. Five days post-transplant, liver function recovered significantly, and renal function gradually improved, eliminating the need for further dialysis. Conclusion: This case demonstrates that emergency liver transplantation is a life-saving option for patients with HRS-AKI unresponsive to medical therapy. It further highlights the importance of early diagnosis and timely referral to a transplant center.

2025-09-29T01:35:55+00:00

Objectives: To describe clinical and paraclinical characteristics and to evaluate complications during postoperative critical care after living donor kidney transplantation at Military Hospital 175. Methods: A retrospective, descriptive study was conducted on 50 patients who underwent living donor kidney transplantation at the Surgical ICU of Military Hospital 175, including patients ≥ 18 years who underwent kidney transplantation from July 2023 to June 2025. Results: the mean age was 42.3 ± 12.1 years; 68% patients were male; the mean BMI was 21.35 ± 2.52 kg/m². Most patients had chronic comorbidities and prolonged pre-transplant dialysis. No severe respiratory complications occurred postoperatively. Vasopressor support was required in 2% of cases. Hypertension requiring treatment was observed in 86% of cases. Early postoperative polyuria and electrolyte disturbances occurred but resolved quickly; serum urea and creatinine levels approached near-normal values by day 3. Complications were observed in 12% of patients (n = 6), including postoperative bleeding requiring reoperation (n = 2), lymphocele (n = 2), and acute rejection (n = 2). Conclusion: Living donor kidney transplantation carries considerable complication risks during the post-resuscitation period. Close postoperative monitoring is essential for timely detection and intervention to optimize outcomes.

URETEROURETEROSTOMY OF THE TRANSPLANTED KIDNEY TO THE NATIVE URETER IN A RECIPIENT WITH DISUSED ATROPHIC BLADDER: A CLINICAL CASE REPORT

2025-08-27T00:17:12+00:00

Patients on long-term hemodialysis often have a disused atrophic bladder, which poses a significant challenge for the reconstruction of the urinary pathway in kidney transplantation. We report the first case at our center in which a recipient with a disused atrophic bladder (capacity 30mL) underwent uretero-ureteral anastomosis. After 29 months of follow-up, graft function remained stable, the bladder showed good capacity expansion > 290mL, and only mild pelvicalyceal dilatation of the graft kidney (6 - 9mm) was observed, without intervention or hydronephrosis of the native kidney. Uretero-ureteral anastomosis should be considered in patients with a disused atrophic bladder to expand kidney transplantation opportunities for long-term dialysis patients.
