Do we really need more evidence to use hepatitis C positive donor kidney more liberally?

ABSTRACT: The number of patients listed active for kidney transplantation has continued to rise over the last 10 years, leading to significantly increased wait-list time for patients awaiting kidney transplantation in the USA. This increased demand has led to a supply-demand mismatch and should prompt clinicians to seek timely solutions to improve access to available organs. Hepatitis C virus positive [HCV(+)] kidneys continue to be discarded without clear evidence that they lead to poor outcomes in the current era of highly efficacious HCV treatment with direct-acting antiviral agents (DAAs). Increased utilization of HCV(+) donor kidneys will decrease wait-list time and improve availability of donor organs. Emerging data suggests that HCV can be successfully treated with DAAs after kidney transplantation with 100% sustained virologic response rates and no significant changes from baseline kidney function. Utilization of HCV(+) donor kidneys should be considered more liberally in the era of highly effective HCV treatment. Further studies are warranted to assess the long-term effect of HCV(+) donor kidneys in transplant recipients in the new era of DAAs.

Kidney Transplantation from a Hepatitis C Virus-positive Donor to a Hepatitis C Virus-negative Recipient.

Project description:Kidney transplantation from a hepatitis C virus (HCV)-positive donor to an HCV-negative recipient till recently has been a contraindication. In view of the excellent sustained virological response (SVR) rates with directly acting antiviral agents, HCV-positive donors are being considered for the HCV-negative recipients in a few centers. We report the successful transplantation of an HCV-negative recipient transplanted with an HCV-positive donor kidney. Donor was treated with sofosbuvir and ribavirin for 12 weeks. At 10th and 16th weeks of starting treatment, her HCV-RNA PCR was negative. Three weeks later, transplantation was performed with basiliximab induction and triple immunosuppression with tacrolimus, mycophenolate, and prednisolone. The recipient was administered sofosbuvir and ribavirin for 12 weeks. He attained good graft function with a stable creatinine. His serial alanine transaminases were normal on 3rd, 6th, and 12th months, respectively. Six months posttransplant his anti-HCV antibody, and HCV-RNA PCR were negative.

Impact of Donor Hepatitis C Virus on Kidney Transplant Outcomes for Hepatitis C-positive Recipients in the Direct-acting Antiviral Era: Time to Revise the Kidney Donor Risk Index?

Project description:BackgroundKidneys from donors with hepatitis C virus (HCV) infection are traditionally considered to be at risk for poorer survival outcomes, as reflected in the kidney donor profile index (KDPI). Modern direct-acting antivirals may modify this risk.MethodsUsing United Network for Organ Sharing data, HCV-infected adult first-time kidney transplant recipients from 2014 to 2017 were examined. Graft and patient survival were compared in a propensity-matched cohort of recipients of HCV antibody (Ab)(+) kidneys versus Ab(-) kidneys. Subsequent analysis was performed in a propensity-matched cohort of recipients of HCV-viremic (RNA positive) versus HCV-naïve kidneys.ResultsThere were 379 recipients each in the matched cohort of recipients of HCV Ab(+) versus HCV Ab(-) kidneys. Despite a higher KDPI (58.2% for HCV Ab[+] versus 38.8% for HCV Ab[-]), 1-year patient and graft survival were similar in the HCV(+) and HCV(-) groups (95.4% and 94.9% versus 97.9% and 96.0%, P = 0.543 and P = 0.834, respectively). There were 200 recipients each in the cohort of recipients of HCV-viremic versus HCV-naïve kidneys, with the KDPI again higher in the HCV-viremic group (56.8% versus 35.2%). Baseline hazard ratios (HRs) for graft failure (HR, 4.69; P = 0.009) and death (HR, 7.60; P = 0.003) were significantly elevated in the viremic group, but crossed 1 at 21 and 24 months, respectively.ConclusionsIn the modern direct-acting antiviral era, calculated likely KDPI overestimates risk kidneys from HCV (+) donors. Donor viremia conveys an early risk which appears to subside over time. These results suggest that it may be time to revise the kidney donor risk index.

Does world heritage list really induce more tourists? Evidence from Macau.

Project description:It is commonly believed that being listed on the World Heritage List (WHL) results in attracting more tourists. However, this assumption has not been generally subject to rigorous econometric approach in the existing literature. To fill this gap, we assess the impact of the accreditation World Heritage status on the "Historic Centre of Macau" in 2005 on visitor numbers to the territory to identify the real effect of WHL on fostering tourism. In doing so, because of the policy restrictions on the mainland Chinese tourists, such tourists have been excluded from the analysis. The empirical results indicate that there is no significant effect of WHL on promoting tourism other than possibly a short-run tourism-enhancing impact. Notably, this effect is particularly relevant to Asian tourists. This paper discusses these results in the wider context of econometric analyses of tourism.

Helping More Patients Receive a Living Donor Kidney Transplant.

Project description:The best treatment option for many patients with kidney failure is a kidney transplant from a living donor. Countries that successfully increase their rate of living kidney donation will decrease their reliance on dialysis, the most expensive and high-risk form of kidney replacement therapy. Outlined here are some barriers that prevent some patients from pursuing living kidney donation and current knowledge on some potential solutions to these barriers. Also described are strategies to promote living kidney donation in a defensible system of practice. Safely increasing the rate of living kidney donation will require better programs and policies to improve the experiences of living donors and their recipients, to safeguard the practice for years to come.

The incidence of cytomegalovirus infection after deceased-donor kidney transplantation from hepatitis-C antibody positive donors to hepatitis-C antibody negative recipients.

Project description:BackgroundDeceased-donor kidney transplantation (KT) from hepatitis C (HCV)-infected donors into HCV-uninfected recipients (HCV D+/R-) could become standard care in the near future. However, HCV viral replication by viral transmission might lead to a higher incidence of cytomegalovirus (CMV) infection in these recipients.MethodsA national-registry-based retrospective cohort study was conducted using the Scientific Registry of Transplant Recipients (SRTR) data set. We assessed the incidence of CMV infection in HCV antibody (Ab) negative recipients receiving kidneys from HCV Ab positive (HCVAb D+/R-) and negative (HCVAb D-/R-) donors. The risk of CMV infection was analyzed by Cox regression analysis in a propensity score (PS) matched-cohort of HCVAb D+/R- (n = 950) versus HCVAb D-/R- (n = 950). Sensitivity analysis was also conducted in the entire cohort (n = 181 082).ResultsThe mean age at baseline was 54 years, 75% were male, and 55% of the patients were African American in PS-matched cohort. Compared to the HCVAb D-/R - patients, recipients with HCVAb D+/R - showed identical probability for the incidence of CMV infection (Hazard Ratio (HR) = 1.00, 95% Confidence Interval (CI): 0.82-1.22). In the sensitivity analysis, compared to the HCVAb D-/R - patients, the HCVAb D+/R - group had a significantly lower risk of CMV infection in the unadjusted analysis (HR = 0.75, 95%CI: 0.65-0.85), while this risk difference disappeared after the adjusted analysis (HR = 0.99, 95%CI: 0.87-1.14).ConclusionThe incidence of CMV infection was similar in recipients who received HCVAb D + and HCVAb D - KT. Further studies are needed to assess this association in KT from HCV nucleic acid positive donors.

Early sedation use in critically ill mechanically ventilated patients: when less is really more.

Project description:Over the last 10 years, there has been an explosion of literature surrounding sedation management for critically ill patients. The clinical target has moved away from an unconscious and immobile patient toward a goal of light or no sedation and early mobility. The move away from terms such as 'sedation' toward more patient-centered and symptom-based control of pain, anxiety, and agitation makes the management of critically ill patients more individualized and dynamic. Over-sedation has been associated with negative ICU outcomes, including longer durations of mechanical ventilation and lengths of stay, but few studies have been able to associate deep sedation with increased mortality.

Do chromosomal inversion carriers really need preimplantation genetic testing?

Project description:PurposeThis study aimed to evaluate the rates of euploidy, aneuploidy, and mosaicism in preimplantation genetic testing for structural rearrangements (PGT-SR) cycles from chromosomal inversion carriers. In addition, this work also focused on assessing the impact of some contributors on the incidence of parental originating aneuploidy and mosaicism.MethodsThis retrospective review enrolled chromosomal inversion carrier couples of whom the females were under 38 years old undergoing PGT-SR at a single academic reproductive center. Subgroups were divided according to the gender of carriers, the inversion type, and the semen parameters of male carriers (male factor infertility (MF) or non-MF). Patient demographics, cycle characteristics, and PGT-SR outcomes were compared among subgroups.ResultsA total of 71 PGT-SR cycles from 57 inversion carrier couples were included for analysis. Among the 283 blastocysts, 48.4% were identified as euploidy, 27.9% as aneuploidy, and the remaining 23.7% as mosaicism. Only 32.9% of aneuploid embryos and 1.5% of mosaic embryos involved the parental inversion chromosomes. Notably, the female inversion carriers seemed to produce more parental originating aneuploid embryos than male inversion carriers (45.5% vs 23.9%, p = 0.044).ConclusionsThe type of inversion and sperm parameters of male chromosomal inversion carriers did not affect the ploidy status of embryos. The incidence of parental originating aneuploidy in inversion carrier couples is lower than expected. For male chromosomal inversion carriers with normal sperm condition whose female partners are under 38 years old, natural conception combined with prenatal diagnosis could be provided as an option during fertility counseling.
