RESUMEN

BACKGROUND: In a phase 3 trial, letermovir was non-inferior to valganciclovir for CMV disease prophylaxis in CMV-seronegative (R-) kidney transplant recipients (KTRs) who received a kidney from a CMV-seropositive donor (D+). Genotypic antiviral resistance and CMV glycoprotein B (gB) genotype are reported. METHODS: Plasma samples with detectable CMV DNA were sequenced for presence of known letermovir and valganciclovir resistance-associated amino acid substitutions (RASs) encoded by CMV gene regions (UL51, UL56, UL89, UL54, UL97) and prevalence of gB (UL55) genotypes (gB1-gB5). RESULTS: 84 of 292 participants in the letermovir and 93 of 297 in the valganciclovir group had evaluable data for ≥1 gene target. Letermovir RASs were not detected in participants who received letermovir prophylaxis; however, 3 had valganciclovir RASs (pUL97). Twelve participants in the valganciclovir group had valganciclovir RASs (pUL54, pUL97); and 1 who did not receive letermovir during the trial also had letermovir RASs (pUL56). All but 1 participant responded to valganciclovir treatment irrespective of breakthrough CMV DNAemia or frequency of RASs. gB1 was the most frequent genotype across all participants and subgroups. CONCLUSION: Letermovir RASs were not detected in the letermovir group, supporting a low risk for development of resistance with letermovir prophylaxis in CMV D+R- KTRs. CLINICAL TRIALS REGISTRATION: ClinicalTrials.gov: NCT03443869, EudraCT: 2017-001055-30.

RESUMEN

BACKGROUND: COVID-19-induced acute respiratory distress syndrome (ARDS) can result in tissue damage and multiple organ dysfunction, especially in kidney transplant recipients (KTRs) receiving immunosuppressive drugs. Presently, single-cell research on COVID-19-induced ARDS is considerably advanced, yet knowledge about ARDS in KTRs is still constrained. METHODS: Single-cell RNA sequencing (scRNA-seq) analysis was performed to construct a comprehensive single-cell immune landscape of the peripheral blood mononuclear cells (PBMCs) of eight patients with COVID-19-induced ARDS, five KTRs with COVID-19-induced ARDS, and five healthy individuals. Subsequently, we conducted a comprehensive bioinformatics analysis, including cell clustering, enrichment analysis, trajectory analysis, gene regulatory network analysis, and cell-cell interaction analysis, to investigate the heterogeneity of the immune microenvironment in KTRs with ARDS. RESULT: Our study revealed that KTRs exhibit significant heterogeneity with COVID-19-induced ARDS compared with those of other individuals, with significant reductions in T cells, as well as an abnormal proliferation of B cells and monocytes. In the context of dual influences from immunosuppression and viral infection, KTRs exhibited more specific plasma cells, along with significant enrichment of dysfunctional GZMB and XAF1 double-positive effector T cells and IFI27-positive monocytes. Additionally, robust communication existed among T cells and monocytes in cytokine signaling. These effects impede the process of immune reconstitution in KTR patients. CONCLUSION: Our findings suggest that KTRs with COVID-19-induced ARDS show elevated antibody levels, impaired T cell differentiation, and dysregulation of innate immunity. In summary, this study provides a theoretical foundation for a comprehensive understanding of COVID-19-induced ARDS in KTRs.

RESUMEN

BACKGROUND: Kidney transplantation (KT) is the preferred modality of kidney replacement therapy with better patient outcomes and quality of life compared with dialytic therapies. This study aims to evaluate the epidemiology, accessibility and availability of KT services in countries and regions around the world. METHODS: This study relied on data from an international survey of relevant stakeholders (clinicians, policymakers and patient advocates) from countries affiliated with the International Society of Nephrology that was conducted from July to September 2022. Survey questions related to the availability, access, donor type and cost of KT. RESULTS: In total, 167 countries responded to the survey. KT services were available in 70% of all countries, including 86% of high-income countries, but only 21% of low-income countries. In 80% of countries, access to KT was greater in adults than in children. The median global prevalence of KT was 279.0 [interquartile range (IQR) 58.0-492.0] per million people (pmp) and the median global incidence was 12.2 (IQR 3.0-27.8) pmp. Pre-emptive KT remained exclusive to high- and upper-middle-income countries, and living donor KT was the only available modality for KT in low-income countries. The median cost of the first year of KT was $26 903 USD and varied 1000-fold between the most and least expensive countries. CONCLUSION: The availability, access and affordability of KT services, especially in low-income countries, remain limited. There is an exigent need to identify strategies to ensure equitable access to KT services for people with kidney failure worldwide, especially in the low-income countries.

RESUMEN

This study assessed humoral and T cell-mediated immune responses to the BNT162b2 vaccine in orthotopic liver transplant (OLT) and lung transplant (LUT) recipients who received three doses of the vaccine from March 2021 at our institution. Serum samples were collected 60 days post-second and third dose to quantify antibodies against the spike region of SARS-CoV-2 while whole blood samples were collected to analyze the SARS-CoV-2-specific T-cell response using an IFN-γ ELISpot assay. We enrolled 244 OLT and 120 LUT recipients. The third dose increased antibody titres in OLT recipients (from a median value of 131 after the second dose to 5523 IU/mL, p < 0.001) and LUT recipients (from 14.8 to 1729 IU/mL, p < 0.001). T-cell response also increased in OLT recipients (from 8.5 to 23 IFN-γ SFU per 250,000 PBMC, p < 0.001) and LUT recipients (from 8 to 15 IFN-γ SFU per 250,000 PBMC, p < 0.001). A total of 128 breakthrough infections were observed: two (0.8%) OLT recipients were hospitalized due to COVID-19 and one died (0.4%); among LUT recipients, seven were hospitalized (5.8%) and two patients died (1.7%). In conclusion, the three-dose schedule of the BNT162b2 vaccine elicited both humoral and T cell-mediated responses in solid organ transplant recipients. The risk of severe COVID-19 post-vaccination was low in this population.

RESUMEN

Inquilinus limosus is an environmental bacterium associated with respiratory tract colonization in cystic fibrosis patients. We report a case of I. limosus bacteremia in a patient in France who received a lung transplant and experienced chronic graft dysfunction and SARS-CoV-2 infection. This case suggests I. limosus displays virulence factors associated with invasion.

RESUMEN

OBJECTIVE: Renal transplant is associated with substantial survival advantage in patients with end-stage renal disease. However, little is known about the outcomes of renal transplant recipients (RTRs) after endovascular abdominal aortic aneurysm repair (EVAR). This study aimed to study the effect of renal transplant on perioperative outcomes and long-term survival after elective infrarenal EVAR. METHODS: The Vascular Quality Initiative database was queried for all patients undergoing elective EVAR from 2003 to 2021. Functioning RTRs were compared with non-renal transplant recipients without a diagnosis of end-stage renal disease (non-RTRs). The outcomes included 30-day mortality, acute kidney injury (AKI), new renal failure requiring renal replacement therapy (RRT), endoleak, aortic-related reintervention, major adverse cardiac events, and 5-year survival. A logistic regression analysis was used to assess the association between RTRs and perioperative outcomes. RESULTS: Of 60,522 patients undergoing elective EVAR, 180 (0.3%) were RTRs. RTRs were younger (median, 71 years vs 74.5 years; P < .001), with higher incidence of hypertension (92% vs 84%; P = .004) and diabetes (29% vs 21%; P = .005). RTRs had higher median preoperative serum creatinine (1.3 mg/dL vs 1.0 mg/dL; P < .001) and lower estimated glomerular filtration rate (51.6 mL/min vs 69.4 mL/min; P < .001). There was no difference in the abdominal aortic aneurysm diameter and incidence of concurrent iliac aneurysms. Procedurally, RTRs were more likely to undergo general anesthesia with lower amount of contrast used (median, 68.6 mL vs 94.8 ml; P < .001) and higher crystalloid infusion (median, 1700 mL vs 1500 mL; P = .039), but no difference was observed in the incidence of open conversion, endoleak, operative time, and blood loss. Postoperatively, RTRs experienced a higher rate of AKI (9.4% vs 2.7%; P < .001), but the need for new RRT was similar (1.1% vs 0.4%; P = .15). There was no difference in the rates of postoperative mortality, aortic-related reintervention, and major adverse cardiac events. After adjustment for potential confounders, RTRs remained associated with increased odds of postoperative AKI (odds ratio, 3.33; 95% confidence interval, 1.93-5.76; P < .001) but had no association with other postoperative complications. A subgroup analysis identified that diabetes (odds ratio, 4.21; 95% confidence interval, 1.17-15.14; P = .02) is associated with increased odds of postoperative AKI among RTRs. At 5 years, the overall survival rates were similar (83.4% vs 80%; log-rank P = .235). CONCLUSIONS: Among patients undergoing elective infrarenal EVAR, RTRs were independently associated with increased odds of postoperative AKI, without increased postoperative renal failure requiring RRT, mortality, endoleak, aortic-related reintervention, or major adverse cardiac events. Furthermore, 5-year survival was similar. As such, while EVAR may confer comparable benefits and technical success perioperatively, RTRs should have aggressive and maximally optimized renal protection to mitigate the risk of postoperative AKI.

RESUMEN

BACKGROUND: Acute kidney injury (AKI) is one of the most common complications after cardiac surgery with cardiopulmonary bypass (CPB). Renal transplant recipients (RTRs) have a higher risk of cardiac surgery-associated AKI (CSA-AKI). A relationship has been strongly suggested between AKI and poor long-term graft survival. The main objective was to evaluate the impact of on-pump cardiac surgery on the 1-year renal allograft survival rate. METHODS: The study population consisted of 37 RTRs and 56 non-RTRs who underwent cardiac surgery between 1 January 2010 and 31 December 2019. They were matched according to age, sex, preoperative glomerular function, diabetes and type of surgery. The primary composite outcome was renal survival, defined as patient survival without the requirement for permanent dialysis or new kidney transplantation at 1 year after surgery. RESULTS: The renal survival rate was significantly lower in the RTR group than in the non-RTR group [81% versus 96%; odds ratio 0.16 (95% confidence interval 0.03-0.82), P = .03]. The proportion of patients who returned to permanent dialysis was higher in the RTR group than in the non-RTR group (12% versus 0%; P = .02). The proportion of patients with severe AKI was also higher in the RTR group. At 1 year after surgery, serum creatinine level, glomerular filtration rate and all-cause mortality rates were comparable between both groups. CONCLUSION: Patients with a functional renal allograft have a low 1-year renal allograft survival rate after cardiac surgery with CPB. In addition, these patients have significant risks of AKI and acute kidney disease after open-heart surgery.

RESUMEN

INTRODUCTION: Living donor liver transplantation (LDLT) is a promising option for mitigating the deceased donor organ shortage and reducing waitlist mortality. Despite excellent outcomes and data supporting expanding candidate indications for LDLT, broader uptake throughout the United States has yet to occur. METHODS: In response to this, the American Society of Transplantation hosted a virtual consensus conference (October 18-19, 2021), bringing together relevant experts with the aim of identifying barriers to broader implementation and making recommendations regarding strategies to address these barriers. In this report, we summarize the findings relevant to the selection and engagement of both the LDLT candidate and living donor. Utilizing a modified Delphi approach, barrier and strategy statements were developed, refined, and voted on for overall barrier importance and potential impact and feasibility of the strategy to address said barrier. RESULTS: Barriers identified fell into three general categories: 1) awareness, acceptance, and engagement across patients (potential candidates and donors), providers, and institutions, 2) data gaps and lack of standardization in candidate and donor selection, and 3) data gaps regarding post-living liver donation outcomes and resource needs. CONCLUSIONS: Strategies to address barriers included efforts toward education and engagement across populations, rigorous and collaborative research, and institutional commitment and resources.

RESUMEN

BACKGROUND: In the general population, prior infection with SARS-CoV-2 reduces the risk of severe COVID-19; however, studies in lung transplant recipients (LTRs) are lacking. We sought to describe the clinical course of COVID-19 recurrence and compare outcomes between the first and second episodes of COVID-19 in LTRs. METHODS: We conducted a retrospective, single-center cohort study of LTRs with COVID-19 between January 1, 2022, and September 30, 2022, during the Omicron wave. We compared the clinical course of a second episode of COVID-19 to that of the patients' own first episode and to that of LTRs who developed a first episode during the study period. RESULTS: During the study period, we identified 24 LTRs with COVID-19 recurrence and another 75 LTRs with a first episode of COVID-19. LTRs who survived the initial episode of COVID-19 had a similar disease course with recurrence, with a trend toward reduced hospitalization (10 (41.6%) vs. 4 (16.7%), p = .114). Furthermore, compared to LTRs with a primary infection during the Omicron wave, those with a reinfection had a non-statistically significant trend toward reduced hospitalizations (aOR .391, 95% CI [.115-1.321], p = .131), shorter lengths-of-stay (median, 4 vs. 9 days, p = .181), and reduced intensive care unit admissions, intubations, and COVID-19-related mortality. CONCLUSIONS: LTRs who survive the first episode of COVID-19 are likely to have a similar clinical course with recurrent episodes. Although recurrent COVID-19 may be milder, larger, well-powered studies are needed to confirm this observation. Ongoing precautions are warranted.

RESUMEN

OBJECTIVE: Comorbid psychiatric disorders negatively affect the survival rate of patients with some physical disorders. In liver transplant recipients, various psychiatric disorders have been identified as worsening prognosis. However, little is known about how the presence of any comorbid (overall) disorders affect the survival rate of transplant recipients. In this study, we examined the effect of overall comorbid psychiatric disorders on survival rate in liver transplant recipients. METHODS: A total of 1006 recipients who underwent liver transplantation between September 1997 and July 2017 across eight transplant facilities with a psychiatric consultation-liaison team were identified consecutively. Recipients were categorized into those with comorbid psychiatric disorders and those without comorbid psychiatric disorders. In the comorbid psychiatric disorder group, psychiatric disorder diagnosis and time of diagnosis were investigated retrospectively. RESULTS: Of the 1006 recipients, 294 (29.2%) had comorbid psychiatric disorders. Comorbid psychiatric disorders in the 1006 recipients were insomnia (N = 107, 10.6%), delirium (N = 103, 10.2%), major depressive disorder (N = 41, 4.1%), adjustment disorder (N = 19, 1.9%), anxiety disorder (N = 17, 1.7%), intellectual disability (N = 11, 1.1%), autism spectrum disorder (N = 7, 0.7%), somatic symptom disorder (N = 4, 0.4%) schizophrenia (N = 4, 0.4%), substance use disorder (N = 24, 2.4%) and personality disorder (N = 2, 0.2%). The most common time of psychiatric disorder diagnosis was within the first 3 months after liver transplantation (51.6%). The final mortality in patients with comorbid psychiatric disorder diagnosis during the five periods (pretransplant, transplant to 3 months, months to 1 year, 1 to 3 years, and over 3 years posttransplant) was 16.2%, 18.8%, 39.1%, 28.6%, and 16.2% respectively, and there were no significant differences between the five periods (χ2 = 8.05, df = 4, p = 0.09). Overall comorbid psychiatric disorders were significantly associated with shorter survival time (log-rank test: p = 0.01, hazard ratio: 1.59 [95% confidence interval: 1.14-2.21], survival rate at the endpoint [%]: 62.0 vs. 83.3). However, after adjusting for confounding variables using Cox proportional hazards regression, there was no significant effect of overall comorbid psychiatric disorders on prognosis. CONCLUSION: Comorbid psychiatric disorders did not affect the survival rate of liver transplant recipients in this study.

RESUMEN

Solid organ transplant recipients (SOTR) frequently report tremor. Data concerning tremor-related impairment and its potential impact on health-related quality of life (HRQoL) are lacking. This cross-sectional study assesses impact of tremor on activities of daily living and HRQoL using validated questionnaires among SOTR enrolled in the TransplantLines Biobank and Cohort Study. We included 689 SOTR (38.5% female, mean [±SD] age 58 [±14] years) at median [interquartile range] 3 [1-9] years after transplantation, of which 287 (41.7%) reported mild or severe tremor. In multinomial logistic regression analyses, whole blood tacrolimus trough concentration was an independent determinant of mild tremor (OR per µg/L increase: 1.11, 95% CI: 1.02 to 1.21, p = 0.019). Furthermore, in linear regression analyses, severe tremor was strongly and independently associated with lower physical and mental HRQoL (ß = -16.10, 95% CI: -22.23 to -9.98, p < 0.001 and ß = -12.68, 95% CI: -18.23 to -7.14, p < 0.001 resp.). SOTR frequently report tremor-related impairment of activities of daily living. Tacrolimus trough concentrations appeared as a main determinant of tremor among SOTR. The strong and independent association of tremor-related impairment with lower HRQoL warrants further studies into the effects of tacrolimus on tremor. Clinical Trial Registration: ClinicalTrials.gov, Identifier NCT03272841.

RESUMEN

BACKGROUND: Aspergillus spp. is an uncommon and life-threatening cause of transplantrenal artery pseudoaneurysm after kidney transplantation. CASE: We report the case of a 62-year-old woman who underwent kidney transplantation 10 months before and presented a 7-cm asymptomatic transplant renal artery pseudoaneurysm. Transplanted kidney and pseudoaneurysm were surgically removed in emergency. Renal graft, urine, and pseudoaneurysm cultures grew Aspergillus flavus. She recovered after 12 months of antifungal therapy. LITERATURE REVIEW: To date 14 cases of Aspergillus spp. renal arteritis after kidney transplantation have been published, including 50% Aspergillus flavus arteritis. Vast majority were diagnosed within 90 days after transplantation (73%). Despite allograft nephrectomy and antifungal therapy, mortality rate was high (33%).

RESUMEN

Actinic keratoses (AKs) are pre-malignant skin lesions that can give rise to squamous cell carcinomas. Involvement of adnexal structures by AKs has been postulated to confer resistance to therapy and facilitate malignant progression. In our study, we identified several factors associated with increased risk of adnexal involvement of AKs. We found an increased risk of follicular involvement in AKs on the head and neck, a slightly increased risk of eccrine involvement with increasing age, and an increased risk of eccrine involvement in organ transplant patients. Additionally, our data showed a higher overall rate of follicular involvement of AKs than previously reported.

RESUMEN

BACKGROUND: History of chronic kidney disease and kidney transplantation is known to influence physical performance capacity. The aim of this study was to compare the physical performance of pediatric kidney transplant recipients to healthy controls and to find possible correlations between clinical parameters and physical performance capacity. METHODS: Twenty-four pediatric kidney transplant recipients (62.5% boys) were tested at a median age of 10.8 years. Physical performance capacity was tested with a test set including six different components assessing muscle endurance, strength, speed, and flexibility. The control group consisted of 273 healthy age-matched schoolchildren. Clinical parameters were collected as part of routine follow-up protocol. The majority of patients (62.5%) had congenital nephrotic syndrome of Finnish type (CNS) as primary diagnosis, and therefore, the results of CNS recipients were compared to the other disease groups. RESULTS: The physical performance capacity in pediatric kidney transplant recipients was lower compared to healthy controls. Surprisingly, no statistically significant correlation was found between graft function and physical performance capacity. The CNS patients scored worse than patients with other diagnoses in all test domains except for sit-and-reach and shuttle run, but the differences did not reach statistical significance. CONCLUSION: The physical performance of pediatric kidney transplant recipients is reduced, especially in those with congenital nephrotic syndrome. Clinical parameters, including graft function, did not predict physical performance capacity, suggesting that the reduced physical performance seems to be of multivariable cause. A higher resolution version of the Graphical abstract is available as Supplementary information.

RESUMEN

BACKGROUND: The COVID-19 pandemic is protracted and episodic surges from viral variants continue to place significant strain on healthcare systems. COVID-19 vaccines, antiviral therapy and monoclonal antibodies have significantly reduced COVID-19 associated morbidity and mortality. Concurrently, telemedicine has gained acceptance as a model of care and a tool for remote monitoring. These advances allow us to safely transit our inpatient-based care for COVID-19 infected kidney transplant recipients (KTRs) to a hospital-at-home (HaH) model of care. METHODS: KTRs with PCR-proven COVID-19 infection were triaged by teleconsult and laboratory tests. Suitable patients were enrolled into the HaH. Remote monitoring via teleconsults were conducted daily until patients were de-isolated based on a time-based criterion. Monoclonal antibodies were administered in a dedicated clinic where indicated. RESULTS: Eighty-one KTRs with COVID-19 were enrolled into the HaH between February and June 2022, 70 (86.4%) completed HaH recovery without complications. Eleven (13.6%) patients required inpatient hospitalization for medical issues (n = 8) and weekend monoclonal antibody infusion (n = 3). Patients requiring inpatient hospitalization had longer transplant vintage (15 years vs. 10 years, p = .03), anaemia (haemoglobin 11.6 g/dL vs. 13.1 g/dL, p = .01), lower eGFR (39.8 vs. 62.9 mL/min/1.73 m2 , p < .05) and lower RBD levels (<50 AU/mL vs. 1435 AU/mL, p = .02). HaH saved 753 inpatient patient-days with no deaths observed. Hospital admission rates from the HaH programme was 13.6%. Patients who required inpatient care had direct access admission without utilization of emergency department resources. CONCLUSION: Selected KTRs with COVID-19 infection can be safely managed in a HaH programme; alleviating strain on inpatient and emergency healthcare resources.

RESUMEN

INTRODUCTION: Thromboembolism is more common in kidney transplant recipients (KTRs) than in the general population. Studies evaluating arterial and venous thromboembolism (VTE) in KTRs are scarce and the magnitude and risk factors are mostly undefined. METHODS: A nested control study was conducted from January 1, 2007, to December 31, 2019. Adult KTRs who were detected to have VTE events during this period were included. The primary outcome was to assess the prevalence of VTE in this population. Secondary outcomes were the assessment of the time to occurrence of the thromboembolic events after transplantation and assessing the risk factors and patient survival. For each subject studied, 4 controls were matched from the data set. RESULTS: Amongst 2158 patients, 97 (4.5%) were found to have VTE. The median follow-up time was 3.9 years (6-156 months). A total of 101 VTE events were recorded. The most common site of VTE was the lower limb deep vein thrombosis in 79 patients (0.03%)).In multivariate Cox regression analysis, serum creatinine of more than 3 mg/dl [HR 1.30, 95% CI (1.03-1.38)] was independently associated with increased VTE risk. Patients who developed a VTE had higher mortality as compared to patients who did not develop VTE. No increased risk of graft failure was found in VTE patients. CONCLUSION: This study suggests that kidney transplantation surgery is a moderate risk factor for VTE, and VTE is associated with higher morbidity and mortality. However, prospective studies are needed to establish a definite role of VTE in outcomes in KTRs.

RESUMEN

Anonymity of deceased organ donation is a legal requirement in many international jurisdictions where legislation prohibits health professionals from disclosing identifiable information about donors, recipients or their families. Written correspondence between donor families and transplant recipients that is coordinated by healthcare professionals must remain anonymous. Internationally, an increasing number of donor families and transplant recipients have advocated for law reform and policy amendment to enable the exchange of identifiable written correspondence and/or face-to-face meetings. This paper aims to synthesise and critically evaluate published, peer-reviewed literature on the perceptions, benefits and challenges of identifiable communication or anonymity between donor families and organ transplant recipients in the international context. Analysis of the findings revealed two major themes: (1) views held by donor families, transplant recipients and healthcare professionals towards identity disclosure in the context of organ donation are diverse across and within groups (2) there are benefits and burdens associated with connecting donor families and transplant recipients through written correspondence. Less is known about the impact of face-to-face meetings between donor families and transplant recipients. However, what is known is that for some donor families, meeting with the transplant recipient(s) may provide a range of positive emotions.

RESUMEN

PURPOSE: High anxiety among kidney transplant recipients has negative psychosocial consequences for health quality. This study aims to determine the risk factors that affect levels of anxiety in recipients of kidney transplants according to living and deceased donor types. DESIGN: The study was conducted using a descriptive correlational research method. METHODS: The study conducted research with 330 kidney transplant recipients (from 261 live and 69 cadaver donors) who agreed to participate between February and July 2019. Participants completed the State-Trait Anxiety Inventory, which assesses state and trait anxiety. FINDINGS: Participants had low state anxiety and moderate trait anxiety scores. A statistically significant, positive, moderate correlation was found between state anxiety scale and trait anxiety scale mean scores of recipients of kidney transplants from both living and deceased donors. According to a regression analysis of trait anxiety scores of transplant recipients from living donors, positive independent risk factors for anxiety include kidney transplant recipients with a low income, receiving kidneys from male donors, drug noncompliance, sleep disorders, and mental problems. CONCLUSIONS: Both kidney transplant recipients from living and deceased donors had low state anxiety and moderate trait anxiety. Nurses should develop effective intervention strategies that continue throughout life to reduce the anxiety of kidney transplant recipients.

RESUMEN

Mucormycosis is a rare invasive fungal disease diagnosed in immunocompromised patients, including those with diabetes or iron overload, and in patients treated for hematological malignancies or after transplantation. Isavuconazole is a triazole antifungal effective against Mucorales with good tolerability, but with potential for relatively high interindividual variability in pharmacokinetics. This report demonstrates the case of a lung transplant recipient treated with isavuconasole that exhibits a very long elimination half-life of 159 hours, and discusses the practical implications of this finding for dosage adjustment and need for therapeutic drug monitoring.

RESUMEN

BACKGROUND: Kidney transplantation is currently the best choice for renal replacement therapy, due to its effect in reducing mortality and improving the quality of life (QoL) of patients with end-stage renal disease. This study aimed to identify factors affecting QoL after kidney transplantation. METHODS: We conducted a cross sectional study by recruiting patients who had kidney transplantation at Cipto Mangunkusumo General Hospital, Jakarta, Indonesia, from 2018 - 2020. QoL was assessed using the 36-item Short Form Health Survey (SF-36) questionnaire. We evaluated age, sex, body mass index, hemoglobin level, estimated glomerular filtration rate, duration of dialysis before transplantation, history of diabetes, depression, and performance status as factors associated with QoL score. RESULTS: We involved 107 subjects in our study. Depression, hemoglobin level, ECOG performance status, and duration of dialysis were factors affecting the physical component score (R2=0.21). Depression and hemoglobin level were factors affecting the mental component score (R2=0.34 ). Depression, hemoglobin level, and ECOG performance status were factors contributed to the total QoL score (R2=0.41). CONCLUSION: Factors that contributed to QoL status were depression, ECOG performance status, and hemoglobin levels. This study supported the need for assessment of QoL on regular basis, psychological aspects including depression, as well as other factors that can affect QoL such as performance status and hemoglobin level in patients before and after kidney transplantations.
