Introduction: The side effects profile of the new direct-­acting antivirals for the treatment of hepatitis C virus (HCV) is not fully elucidated. Objective: In this cross-sectional study, we aim to describe the incidence and characteristics of a novel observation of de novo renal cryoglobulinemic glomerulonephritis after successful treatment with DAA. Methodology: A total of 12,985 Hepatitis C Patients (genotype IV) received the new DAA. After successful treatment, patients with deranged renal functions or proteinuria were referred to the nephrology department for assessment. The clinical manifestations ranged from lower limb edema to the development of purpura skin lesions. Cryoglobulins were tested in the serum using the PCR detection. Results: Fifty patients had detectable de novo cryoglobulins in the serum. The most common type in renal biopsies was membranoproliferative glomerulonephritis (52%) and chronic kidney disease (CKD) developed in 46% of cases. Conclusion: De novo cryoglobulinemic glomerulonephritis and progression to CKD may rarely complicate successful treatment of HCV using direct-acting antivirals.

Purpose Diabetes mellitus (DM) increases the risk of morbidity and mortality after liver resection. Albuminuria is associated with a higher risk for all-cause and cardiovascular mortality. This study evaluated albuminuria as a predictor of the outcome of living donor liver transplantation (LDLT) in patients with pre-existing DM. Methods This retrospective study involved 103 type II diabetic patients with end-stage liver disease who received LDLT. Preoperative spot urine albumin: creatinine ratio was used to determine the degree of albuminuria. The primary outcome measure was the impact of urinary albumin excretion on the 3-year mortality rate after LDLT in this diabetic cohort. Results Hepatitis C virus infection was the main cause of cirrhosis. Albuminuria was detected in 41 patients (39.8%); 15 had macroalbuminuria, while 26 had microalbuminuria. Patients with microalbuminuria were significantly older than those with macroalbuminuria and normal albumin in urine. After 3 years, twenty-four patients (23.3%) died within 3 years after LT. Myocardial infarction was the leading cause of death (25%). Albuminuria was an independent factor affecting 3-year mortality with an odds ratio of 5.17 (95% CI: 1.86–14.35). Conclusion Preoperative albuminuria is an independent factor affecting mortality within 3 years after LDLT in type II diabetic patients. Myocardial infarction was the leading cause of death in 25% of cases, followed by hepatocellular carcinoma recurrence, sepsis, and graft failure. KEY MESSAGES Diabetes mellitus (DM) increases the risk of morbidity and mortality after liver resection. Albuminuria is associated with a higher risk for all-cause and cardiovascular mortality. Preoperative albuminuria is a significant predictor of mortality within 3 years after LDLT in diabetic patients.
