Insights
Chronic kidney disease (CKD) is significantly associated with viral hepatitis (hepatitis B virus and hepatitis C virus) in Oman. Hepatitis C virus infection showed the highest CKD prevalence, emphasizing the need for kidney function monitoring.
Area of Science:
- Nephrology
- Hepatology
- Epidemiology
Background:
- Chronic kidney disease (CKD), hepatitis B virus (HBV), and hepatitis C virus (HCV) are prevalent in Oman.
- A significant association between viral hepatitis and CKD risk has been suggested.
Purpose of the Study:
- To investigate the association between CKD and viral hepatitis (HBV and HCV) in Oman.
- To evaluate the prevalence of CKD in patients with chronic HBV, chronic HCV, and HBV/HCV coinfection.
Main Methods:
- An observational cohort study was conducted at the Royal Hospital, Sultanate of Oman.
- 233 patients were analyzed: 112 with chronic HBV, 112 with chronic HCV, and 9 with coinfection.
- Prevalence of CKD and mean estimated glomerular filtration rate (eGFR) were calculated for each group.
Main Results:
- CKD prevalence was 51% in HBV, 78% in HCV, and 56% in coinfection groups.
- Mean eGFR was lowest in the coinfection group (57.6 mL/min/1.73 m²).
- HCV infection showed the highest CKD prevalence and the fastest decline in renal function.
Conclusions:
- Viral hepatitis, particularly HCV infection and coinfection, is significantly and independently associated with an increased risk of CKD.
- Close monitoring of kidney function is crucial for patients with viral hepatitis.
- Screening for viral hepatitis is recommended for patients diagnosed with CKD.
Abstract:
Chronic kidney disease (CKD), hepatitis B virus (HBV), and hepatitis C virus (HCV) have a high prevalence in Oman. This study aimed to examine the association between CKD and viral hepatitis through an observational cohort study conducted at the Royal Hospital of the Sultanate of Oman to evaluate the relationship of HBV and HCV with CKD. During the study, 233 patients were identified, 112 with chronic HBV (Group 1), 112 with chronic HCV (Group 2), and nine with HBV and HCV coinfection (Group 3). The population was predominantly male, especially in Groups 1 and 3. The difference in age between Groups 1 and 2 was significant, with the mean age being 48 ± 14.6 years and 55 ± 12.6 years, respectively (P <0.05). This study revealed that the prevalence of CKD in Group 1 is 51%, in Group 2 was 78%, and in Group 3 was 56%. The mean estimated glomerular filtration rate (eGFR) was 79.7 mL/min/1.73 m2 in Group 1, 73.2 mL/min/1.73 m2 in Group 2, and 57.6 mL/min/1.73 m2 in Group 3. CKD had the highest prevalence in Group 2. The lowest eGFR was found in Group 3. Group 2 showed the highest rate of declining renal function over time despite treatment. This study found a significant and independent association between viral hepatitis and the risk of CKD, especially in cases of coinfection and HCV infection. This warrants close monitoring of kidney function during screening and follow-up. Patients with CKD should be screened for viral hepatitis.
