ABSTRACT: BACKGROUND: Cirrhotic patients with ascites are prone to develop various infectious diseases. This study aimed to evaluate the occurrence and effect of major infectious diseases on the mortality of cirrhotic patients with ascites. METHODS: We reviewed de-identified patient data from the National Health Insurance Database, derived from the Taiwan National Health Insurance Program, to enroll 4,576 cirrhotic patients with ascites, who were discharged from Taiwan hospitals between January 1, 2004 and June 30, 2004. We collected patients' demographic and clinical data, and reviewed diagnostic codes to determine infectious diseases and comorbid disorders of their hospitalizations. Patients were divided into an infection group and non-infection group and hazard ratios (HR) were determined for specific infectious diseases. RESULTS: Of the total 4,576 cirrhotic patients with ascites, 1,294 (28.2%) were diagnosed with infectious diseases during hospitalization. The major infectious diseases were spontaneous bacterial peritonitis (SBP) (645, 49.8%), urinary tract infection (151, 11.7%), and pneumonia (100, 7.7%). After adjusting for patients' age, gender, and other comorbid disorders, the HRs of infectious diseases for 30-day and 90-day mortality of cirrhotic patients with ascites were 1.81 (1.54-2.11) and 1.60 (1.43-1.80) respectively, compared to those in the non-infection group. The adjusted HRs of pneumonia, urinary tract infection (UTI), spontaneous bacterial peritonitis (SBP), and sepsis without specific focus (SWSF) were 2.95 (2.05-4.25), 1.32 (0.86-2.05), 1.77 (1.45-2.17), and 2.19 (1.62-2.96) for 30-day mortality, and 2.57 (1.93-3.42), 1.36 (1.01-1.82), 1.51 (1.29-1.75), and 2.13 (1.70-2.66) for 90-day mortality, compared to those in the non-infection group. CONCLUSION: Infectious diseases increased 30-day and 90-day mortality of cirrhotic patients with ascites. Among all infectious diseases identified, pneumonia carried the highest risk for mortality.

ABSTRACT: BACKGROUND: We noted only rare reports of cirrhotic patients with bacterial endocarditis (BE). There is insufficient data on the risk of BE in liver cirrhosis. This is the first national population-based study evaluating the risk of BE in cirrhotic patients. METHODS: We used the National Health Insurance Database, which is derived from the Taiwan National Health Insurance Program. The study cohort comprised 40 803 patients with cirrhosis and the comparison cohort consisted of 40 841 randomly selected subjects with a similar age and sex distribution. RESULTS: Of the total 81 644 patients, 192 (0.24%) experienced BE during the 3-year follow-up period, 121 patients from the study cohort (0.30% of the cirrhotic patients) and 71 patients from the comparison group (0.17% of non-cirrhotic patients) (p<0.001). After adjusting for patient age, sex, and comorbid disorders, the Cox regression analysis showed that cirrhotic patients had a high risk of BE compared to non-cirrhotic patients during the 3-year follow-up period (hazard ratio 2.04, 95% confidence interval 1.61-2.44, p<0.001). CONCLUSION: We conclude that liver cirrhosis is a risk factor for the occurrence of BE.

ABSTRACT: Cellulitis is a common infectious disease. However, the risk of cellulitis in cirrhotic patients is not well established, and whether liver cirrhosis is a risk factor for cellulitis remains unknown. This study evaluated the relationship between cellulitis and liver cirrhosis.
The National Health Insurance Database, which was derived from the Taiwan National Health Insurance program, was used to identify patients. The study group consisted of 39,966 patients with liver cirrhosis, and the comparison group consisted of 39,701 randomly selected age- and sex-matched patients.
During the 3-year follow-up period, 2,674 (6.7%) patients with liver cirrhosis developed cellulitis, and 1,587 (4.0%) patients without liver cirrhosis developed cellulitis (p<0.001). Following a Cox's regression analysis adjusted for age, sex, and underlying medical disorders, the cirrhotic patients demonstrated a greater risk for the occurrence of cellulitis than the non-cirrhotic patients during the 3-year period (hazard ratio [HR], 1.66; 95% confidence interval [CI], 1.55 to 1.77; p<0.001). Additionally, cirrhotic patients with complications also had a greater risk for the occurrence of cellulitis than those patients without complications (HR, 1.23; 95% CI, 1.14 to 1.33; p<0.001).
We conclude that cirrhotic patients have a greater risk of cellulitis than non-cirrhotic patients.

ABSTRACT: The effects of end-stage renal disease (ESRD) on the mortality of patients with cirrhosis and spontaneous bacterial peritonitis (SBP) have not been determined.
We collected data from Taiwan's National Health Insurance Database on 2592 patients with cirrhosis who were hospitalized with SBP from January 1 to December 31, 2004. Patients were matched with individuals from a national mortality database; 30-day and 1-year mortalities were calculated for each group and compared to calculate hazard ratios (HRs).
Of the patients with cirrhosis and SBP, 300 (11.5%) had renal function impairment. Of these, 145 had acute renal failure, 70 had ESRD, and 75 had chronic kidney disease. Overall, 30-day and 1-year mortality were 21.3% and 51.7%, respectively. After adjusting for age, sex, and underlying comorbidities, HRs for 30-day mortality from renal function impairment, acute renal failure, ESRD, and chronic kidney disease were 3.00, 4.68, 1.93, and 1.37, respectively. The HRs for 1-year mortality from renal function impairment, acute renal failure, ESRD, and chronic kidney disease were 2.03, 2.78, 1.70, and 1.37, respectively. The adjusted HRs for 30-day and 1-year mortality of patients with acute renal failure were 2.6 and 1.6, respectively, compared with patients with ESRD.
Acute renal failure is a better determinant of 30-day and 1-year mortality than renal function impairment in cirrhotic patients with SBP.

ABSTRACT: The relationship between osteonecrosis of the femoral head (OFH) and liver cirrhosis is controversial. The aim of this study was to determine whether liver cirrhosis is associated with the occurrence of OFH.
We used the National Health Insurance Database, derived from the Taiwan National Health Insurance program. The study cohort comprised 40,769 adult patients with liver cirrhosis. The comparison cohort consisted of 40,769 randomly selected age- and sex-matched subjects.
During the 3-year follow-up period, there were 321 (0.8%) cirrhotic patients with OFH, and 126 (0.3%) non-cirrhotic patients with OFH (p<0.001). Cox's regression analysis, adjusted by the patients' age, sex, and other confounding factors, showed that the cirrhotic patients had a higher risk for occurrence of OFH than non-cirrhotic patients during the 3-year period (hazard ratio=2.38, p<0.001). In this 3-year study, the incidence density of cirrhotic patients hospitalized for OFH was 3 episodes/1,000 person-year.
We conclude that cirrhotic patients have a higher risk for occurrence of OFH than non-cirrhotic patients.
