    Abstract Data regarding long-term outcomes following renal transplantation in patients with hepatitis C virus (HCV) infection have been controversial. Our aim was to determine whether there is a difference in outcomes between patients with HCV and more advanced fibrosis on pretransplant biopsy and those with minimal or no fibrosis. Patients were divided according to the severity of fibrosis and their outcomes (including acute rejection, chronic rejection, re-initiation of dialysis, progression of liver disease and mortality) were compared. Thirty-one patients with minimal or no fibrosis (Scheuer stages 0 and 1: Group-A) and 10 patients with more advanced fibrosis (Scheuer stages 2 and 3: Group-B) were included in the final data analysis. Acute rejection occurred in 29% (9/31) of the patients with minimal and 30% (3/10) of the patients with advanced fibrosis (P = 0.95), while chronic allograft nephropathy occurred in 6.5% (2/31) of the patients without and 50% (5/10) of the patients with fibrosis (P = 0.006). None of the patients without fibrosis required re-initiation of dialysis compared with 50% (5/10) of the patients with fibrosis (P <0.05). Median graft survival was 46 months and 18 months for patients with minimal and advanced fibrosis, respectively. There were four deaths among patients with advanced and three deaths among patients with minimal fibrosis (P = 0.04). Our data suggests that patients with chronic HCV and more advanced fibrosis on liver biopsy who undergo a renal transplant have a higher incidence of chronic rejection, graft failure and mortality following renal transplant compared with those with minimal fibrosis.

    Abstract Abstract Background The COVID-19 pandemic, caused by SARS-CoV-2 virus, has resulted in over 100,000 deaths in the USA. Our institution has treated over 2000 COVID-19 patients during the pandemic in New York City. The pandemic directly impacted cancer patients and the organization of cancer care. Mount Sinai Hospital has a large and diverse multiple myeloma (MM) population. Herein, we report the characteristics of COVID-19 infection and serological response in MM patients in a large tertiary care institution in New York. Methods We performed a retrospective study on a cohort of 58 patients with a plasma-cell disorder (54 MM, 4 smoldering MM) who developed COVID-19 between March 1, 2020, and April 30, 2020. We report epidemiological, clinical, and laboratory characteristics including the persistence of viral detection by polymerase chain reaction (PCR) and anti-SARS-CoV-2 antibody testing, treatments initiated, and outcomes. Results Of the 58 patients diagnosed with COVID-19, 36 were hospitalized and 22 were managed at home. The median age was 67 years; 52% of patients were male and 63% were non-White. Hypertension (64%), hyperlipidemia (62%), obesity (37%), diabetes mellitus (28%), chronic kidney disease (24%), and lung disease (21%) were the most common comorbidities. In the total cohort, 14 patients (24%) died. Older age (> 70 years), male sex, cardiovascular risk, and patients not in complete remission (CR) or stringent CR were significantly (p < 0.05) associated with hospitalization. Among hospitalized patients, laboratory findings demonstrated elevation of traditional inflammatory markers (CRP, ferritin, D-dimer) and a significant (p < 0.05) association between elevated inflammatory markers, severe hypogammaglobulinemia, non-White race, and mortality. Ninety-six percent (22/23) of patients developed antibodies to SARS-CoV-2 at a median of 32 days after initial diagnosis. The median time to PCR negativity was 43 (range 19–68) days from initial positive PCR. Conclusions Drug exposure and MM disease status at the time of contracting COVID-19 had no bearing on mortality. Mounting a severe inflammatory response to SARS-CoV-2 and severe hypogammaglobulinemia was associated with higher mortality. The majority of patients mounted an antibody response to SARS-CoV-2. These findings pave a path to the identification of vulnerable MM patients who need early intervention to improve outcomes in future outbreaks of COVID-19.
