Introduction and aim of the work Patients infected with hepatitis B virus (HBV) or hepatitis C virus (HCV) are at increased risk of renal disease. This study compares factors associated with proteinuria and doubling of serum creatinine level in patients who were infected with HCV or HBV alone with those who were coinfected with HCV and HBV. Materials and methods The study was performed on 1243 patients who were diagnosed with HBV and/or HCV at the Cairo University Hospitals. All the included subjects underwent urine analysis for proteinuria and serum creatinine level. Clinical characteristics were recorded at baseline and at last follow-up. Results Of 1243 patients, 293 (23.6%) patients had proteinuria. Subset analysis of the patients with proteinuria showed that 10.6% were HBV infected, 63.8% were HCV infected, and the remaining 25.6% were coinfected with both HBV and HCV. Overall, coinfection with both viruses (P=0.01), lower serum albumin (P=0.001), hypertension (P=0.01), and diabetes (P=0.001) were associated with an increase in risk of proteinuria. Coinfection (P=0.001), presence of HBV (P=0.001), and increasing HCV RNA level in patients with HCV and in coinfected patients (P=0.05) was associated with doubling of serum creatinine level. Conclusion The patients coinfected with HBV and HCV are at greater risk of clinically significant proteinuria and loss of renal function owing to complex virological profile. Progressive loss of renal function in that population is associated with markers of viral activity such as proteinuria and increasing HCV RNA levels among HCV-infected patients.
