Frequency, pattern and short-term outcome of chronic renal dysfunction in patients with cirrhosis: a prospective study using HRS and ADQI-IAC criteria
(Lippincott Williams And Wilkins, 2014) de Silva, S.T.; Perera, R.P.; Niriella, M.A.; Pathmeswaran, A.; de Silva, H.J.
BACKGROUND: Diagnostic criteria of hepatorenal syndrome type 2 (HRS2) fail to detect milder degrees of chronic renal dysfunction (CRD) in cirrhosis and exclude patients with pre-existing kidney disease. Definitions addressing this have been proposed by Working Party of the Acute Dialysis Quality Initiative and International Ascites Club (ADQI-IAC). AIMS: We studied the frequency, pattern and short-term outcome of CRD in patients with cirrhosis, using both HRS2 and ADQI-IAC criteria. PATIENTS AND METHODS: Consecutive patients with cirrhosis and stable serum creatinine for 3 months or more attending outpatient clinics in Colombo North Teaching Hospital (Ragama, Sri Lanka) were prospectively recruited and followed up. RESULTS: Of 277 patients with cirrhosis and stable serum creatinine, 23 (8.3%) fulfilled criteria for HRS2, and 65/277 (23.5%) had estimated glomerular filtration rate (eGFR) less than 60 ml/min/1.73 m [ADQI-IAC definition of chronic kidney disease (CKD)]. This included the 23 patients with HRS2 and an additional 42/65 (64.6%) who did not fulfil diagnostic criteria for HRS2 (non-HRS2 CKD). In all, 58/277 (20.9%) died during follow-up [mean 9.8 months (SD 4.5)]. This included 12/23 (52.2%) with HRS2 and 14/42 (33.3%) with non-HRS2 CKD. On the basis of multiple regression model, Child-Turcotte-Pugh class and CRD were significantly associated with death. After correcting for Child-Turcotte-Pugh class, both HRS2 (odds ratio 4.56, 95% confidence interval 1.79-11.53) and non-HRS2 CKD (odds ratio 2.19, 95% confidence interval 1.02-4.68) were independently associated with death. CONCLUSION: Compared with HRS2 criteria, eGFR less than 60 ml/min/1.73 m detected almost twice the number of cirrhotics with CRD. Patients with eGFR less than 60 ml/min/1.73 m who did not fulfil criteria for HRS2 also had significant short-term mortality. ADQI-IAC criteria thus appear to be a more useful definition of CRD in cirrhotics.

It distributed 230 questionnaireswithinthe Western province of Sri Lanka followed by convenient sampling method and finallyanalysis was done based on 204 questionnaires properly filled. It employed StructuralEquation Model (SEM) by using AMOS-21 statistic package to do the hypotheses testing after Confirmatory Factor Analysis (CFA) is executed. Data analysis process followed the essentials for the dataset for normality and sample adequacy before employing the factor analysis for CFA.
