[PMID: 38129888 PMCID: PMC10740300 DOI: 10.1186/s40360-023-00722-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2023] [Accepted: 12/06/2023] [Indexed: 12/23/2023] Open
Abstract
BACKGROUND Previously, observational studies showed that amlodipine can mitigate calcineurin inhibitor- and contrast-induced acute kidney injury (AKI). Herein, we aimed to measure the effect of amlodipine on renal ischemia/reperfusion (I/R) injury and find the underlying mechanisms. MATERIALS AND METHODS Bilateral renal I/R was induced by clamping the hilum of both kidneys for 30 min. The first dose of amlodipine 10 mg/kg was gavaged before anesthesia. The second dose of amlodipine was administered 24 h after the first dose. Forty-eight hours after I/R, rats were anesthetized, and their blood and tissue specimens were collected. RESULTS Amlodipine significantly decreased the elevated serum levels of creatinine and blood urea nitrogen (BUN) and mitigated tissue damage in hematoxylin & eosin (H&E) staining. Amlodipine strongly reduced the tissue levels of malondialdehyde (MDA), interleukin 1β (IL1β), and tumor necrosis factor α (TNF-α). Amlodipine enhanced antioxidant defense by upregulating nuclear factor erythroid 2-related factor 2 (Nrf2) and Sestrin2. Furthermore, amlodipine significantly improved mitochondrial biogenesis by promoting Sestrin2/peroxisome proliferator-activated receptor-gamma coactivator (PGC-1α)/mitochondrial transcription factor A (TFAM) pathway. It also enhanced autophagy and attenuated apoptosis, evidenced by increased LC3-II/LC3-I and bcl2/bax ratios after renal I/R. CONCLUSION These findings suggest that amlodipine protects against renal I/R through Nrf2/Sestrin2/PGC-1α/TFAM Pathway.

Abstract
The occurrence of secondary neoplasms in adult patients treated with chemotherapy in childhood is not uncommon. Prior chemotherapy is found to be an independent risk factor for the development of secondary malignancies, which are usually associated with a worse prognosis. The presented case is a 35-year-old female patient who was diagnosed with Ewing sarcoma in her late adolescence. The tumor was successfully treated with chemotherapy, but 3 years later she was diagnosed with T-cell lymphoblastic lymphoma. The patient received allogeneic hematopoietic stem cell transplantation (allo-HSCT) from human leukocyte antigen (HLA) matched related donor. The procedure was complicated by grade 2 acute graft-versus-host disease (GvHD) which resolved after implementation of immunosuppressive treatment. However, a year later, the patient developed extensive chronic GvHD (cGvHD) and required reintroduction of immunosuppressants. Prolonged immunosuppressive treatment with tacrolimus led to irreversible kidney failure. After a 2-year period of regular peritoneal dialysis, she was found to be eligible for a kidney transplant from a deceased donor. Now, 15 years after stem cell transplantation and 8 years after kidney transplantation, the patient remains in good condition overall, presenting with symptoms of limited cGvHD. The case described here presents a unique clinical scenario of a female patient who was successfully treated for her double malignancy. Moreover, she underwent effective double transplantations and was eventually found to be cured despite accompanying complications.

Acute kidney injury within 100 days post allogeneic hematopoietic cell transplantation is associated with increased risk of post-transplant complications and poor transplant outcomes. Bone Marrow Transplant 2022; 57:1411-1420. [PMID: 35752740 DOI: 10.1038/s41409-022-01744-0] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2021] [Revised: 06/01/2022] [Accepted: 06/14/2022] [Indexed: 11/09/2022]
Abstract
Allogeneic hematopoietic cell transplantation (HCT) offers cure for some patients with hematological diseases but is associated with significant risk of morbidity and mortality. We investigated the incidence of AKI and its impact on transplant outcomes among 408 patients transplanted at Princess Margaret Hospital Cancer Centre, Toronto, Canada. The overall incidence of AKI at 100 days was 64.2%. Compared to those with no AKI, patients who developed AKI had inferior 2-y overall survival (OS), 44.7% vs. 62.4% (P = 0.0004), higher 2-y transplant related mortality (TRM) 36.8% vs. 18.7% (P = 0.0003), lower 2-y graft-vs-host disease (GVHD)- and relapse-free survival (GRFS), 21.0% vs. 39.8% (P = 0.0002), and higher 100-day grade 3-4 acute GVHD (aGVHD), 12.4% vs. 6.3% (P = 0.01). There was no difference in 2-y incidence of relapse between the AKI and non-AKI groups, 24.2% vs. 24.3% (P = 0.84), 100-day grade 2-4 aGVHD, 27.7% vs. 25.7 (P = 0.41) or 2-y moderate-severe chronic GVHD, 24.0% vs. 21.6% (P = 0.79). Patients who develop AKI within 100 days of HCT have inferior OS and GRFS with higher rates of TRM and grade 3-4 aGVHD. These results highlight the importance of close monitoring of renal function, multidisciplinary collaboration, and implementation of protective strategies throughout HCT to optimize transplant and kidney outcomes.

Abstract
Hematopoietic stem cell transplantation (SCT) provides a curative option for the treatment of several malignancies. Its growing use is associated with an increased burden of kidney disease. Acute kidney injury is usually seen within the first 100 days of transplantation and has an incidence ranging between 12 and 73%, with the highest rate in myeloablative allogeneic SCT. A large subset of patients after SCT develop chronic kidney disease. They can be broadly classified into thrombotic microangiopathy, nephrotic syndrome, and calcineurin toxicity. Dialysis requirement after SCT is associated with mortality exceeding 80%. Given the higher morbidity and mortality related to development kidney disease, nephrologists need to be aware of the various causes and best treatment options.

Abstract
Background and objectives Acute kidney injury (AKI) is a major complication of allogeneic hematopoietic stem cell transplantation, increasing risk of non-relapse mortality. AKI etiology is often ambiguous due to heterogeneity of conditioning/graft-versus-host disease (GVHD) regimens. To date, GVHD and calcineurin inhibitor effects on AKI are not well defined. We aimed to describe AKI and assess pre/post-hematopoietic transplant risk factors in a large recent cohort. Design, setting, participants, and measurements We performed a single-center retrospective study of 616 allogeneic hematopoietic cell transplant recipients from 2014-2017. We defined AKI and CKD based on KDIGO criteria and estimated GFR using CKD-EPI equation. We assessed AKI pre/post-hematopoietic transplant risk factors using cause-specific Cox regression and association of AKI with CKD outcomes using Chi-squared test. AKI was treated as a time-dependent variable in relation to non-relapse mortality. Results Incidence of AKI by day-100 was 64%. Exposure to tacrolimus and other nephrotoxins conferred a higher risk of AKI, but tacrolimus levels were not associated with severity. Reduced intensity conditioning carried higher AKI risk compared to myeloablative conditioning. Most stage 3 AKIs were due to ischemic acute tubular necrosis and CNI nephrotoxicity. Kidney replacement therapy was initiated in 21/616 (3%) of whom 9/21 (43%) recovered and 5/21 (24%) survived to hospital discharge. T-cell depleted transplants, higher baseline albumin, and non-Hispanic ethnicity were associated with lower risk of AKI. CKD developed in 21% (73/345) of patients after 12 months. Non-relapse mortality was higher in those with AKI (HR 2.77, 95% CI: 1.8-4.27). Conclusions AKI post-hematopoietic cell transplant remains a major concern. Risk of AKI was higher with exposure to CNIs. T cell depleted hematopoietic cell transplants and higher albumin had lower risk of AKI. Forty-three percent of patients requiring KRT recovered kidney function. Prospective studies are needed to further assess modification of these risk factors.

Update on Treatment of Hypertension After Renal Transplantation. Curr Hypertens Rep 2021; 23:25.

Abstract
PURPOSE OF REVIEW To incorporate novel findings on pathophysiology and treatment of posttransplant hypertension. RECENT FINDINGS (1) The sodium retaining effects of CNIs are mediated by stimulation of the thiazide-sensitive sodium chloride co-transporter in the distal convoluted tubule and in this regard chlorthalidone was proven to be an effective antihypertensive drug in renal transplantation. (2) Local and not systemic activation of the renin-angiotensin-aldosterone system plays a crucial role in the pathogenesis of posttransplant hypertension. (3) Recent randomized controlled trials failed to prove the presumed superiority of renin-angiotensin blockers in kidney transplantation. (4) Steroid-free and mammalian target of rapamycin-based immunosuppressive drug combinations did not show favorable effects on blood pressure control. (5) In a recent report the risk of non-melanoma skin cancer was higher with thiazide diuretics. But the increased cancer risk in transplant recipients is mainly attributed to comorbidities, such as diabetes and hypertension and of course to the transplantation condition itself or the obligatory application of immunosuppression, and has little to do with the antihypertensive medication Actual recommendations about BP targets in adult renal transplant recipients are coming from a post hoc analysis of a large randomized trial with another primary endpoint. Unless convincing studies on treatment of hypertension after renal transplantation are available, the ESC/ESH Guidelines 2018 should apply for these patients.
