No Increased Risk for Primary Osteoarthritis in Liver Cirrhosis - A Danish Nationwide Cohort Study.

ABSTRACT:

Objective

Chronic synovial inflammation causes primary osteoarthritis, but it is unknown whether chronic systemic inflammation does, too. Patients with cirrhosis have chronic systemic inflammation and therefore we examined the association between cirrhosis and primary osteoarthritis of the hip and knee.

Methods

In Danish healthcare databases we identified all residents over 60 years diagnosed with cirrhosis in 1994-2011, and for each of them we sampled five age- and gender-matched reference persons from the general population. We excluded everyone with risk factors for secondary osteoarthritis and computed incidence rates of primary osteoarthritis of the hip or knee. We used stratified Cox regression to estimate the hazard ratios of primary osteoarthritis for cirrhosis patients vs. reference persons in strata defined by gender, age, cirrhosis etiology, and ascites vs. no ascites. We also computed separate HRs for primary osteoarthritis of the hips or knees.

Results

We identified 10,049 cirrhosis patients. Their median age was 67 years, and 65% were men. Among the cirrhosis patients the crude incidence rate of primary osteoarthritis was 8.40 (95% CI: 7.30-9.63) per 1000 person-years. The rate was similar in the reference persons: 8.76 (95% CI: 8.43-9.12) per 1000 person-years. Accordingly, the hazard ratio for primary osteoarthritis for cirrhosis patients vs. reference persons was 0.99 (95% CI: 0.85-1.16), and we found the same null association in all patient strata and in both joints.

Conclusion

Cirrhosis, and thus chronic systemic inflammation, is not a risk factor for primary osteoarthritis.

Project description:BACKGROUND: Low socioeconomic status is a risk factor for liver cirrhosis, but it is unknown whether it is a prognostic factor after cirrhosis diagnosis. We examined whether marital status, employment, and personal income were associated with the survival of cirrhosis patients. METHODS: Using registry-data we conducted a population-based cohort study of 1,765 Danish cirrhosis patients diagnosed in 1999-2001 at age 45-59 years. Follow-up ended on 31 December 2003. With Cox regression we examined the associations between marital status (never married, divorced, married), employment (employed, disability pensioner, unemployed), personal income (0-49, 50-99, 100+ percent of the national average) and survival, controlling for gender, age, cirrhosis severity, comorbidity, and substance abuse. RESULTS: Five-year survival was higher for married patients (48%) than for patients who never married (40%) or were divorced (34%), but after adjustment only divorced patients had poorer survival than married patients (adjusted hazard ratio for divorced vs. married = 1.22, 95% CI 1.04-1.42). Five-year survival was lower for disability pensioners (31%) than for employed (46%) or unemployed patients (48%), also after adjustment (adjusted hazard ratio for disability pensioners vs. employed = 1.35, 95% CI 1.09-1.66). Personal income was not associated with survival. CONCLUSION: Marital status and employment were associated with the survival of cirrhosis patients. Specifically, divorced cirrhosis patients and cirrhosis patients who never married had a poorer survival than did married cirrhosis patients, and cirrhosis patients who were disability pensioners had a poorer survival than did employed or unemployed cirrhosis patients. The poorer survival for the divorced and for the disability pensioners could not be explained by differences in other socioeconomic factors, gender, age, cirrhosis severity, substance abuse, or comorbidity. Personal income was not associated with survival.

Project description:Liver cirrhotic predisposes patients to coagulopathy and bleeding. Little is known about outcomes of acute myocardial infarction (AMI) in cirrhotic patients.Data from Taiwan National Health Insurance Research Database during 2001 to 2013 were retrieved for patients admitted with cirrhosis and AMI. We excluded patients with missing information, <20 years old, previous AMI, previous coronary intervention, and liver transplant. Patients were separated into cirrhotic and non-cirrhotic. Primary outcomes included all-cause mortality, recurrent myocardial infarction (MI), major cardiac and cerebrovascular events (MACCE: recurrent MI, revascularization, ischemic stroke, and heart failure), and liver outcomes (hepatic encephalopathy, ascites tapping, spontaneous peritonitis, and esophageal varices bleeding).A total of 3217 cirrhotic patients and 6434 non-cirrhotic patients were analyzed, with a mean follow up of 2.8?±?3.3 years. In cirrhotic patients with AMI, subsequent coronary and cerebrovascular events were lower in comparison to non-cirrhotic patients, with higher all-cause mortality observed from adverse liver related outcomes and bleeding. There were significantly lower cumulative incidence of both recurrent MI and MACCE in cirrhotic patients with AMI compared with non-cirrhotic patients with AMI (hazard ratio [HR] 0.82, confidence interval [CI] 0.71-0.94, P?=?.006 and HR 0.86, 95% CI 0.79-0.92, P?<?.001, respectively). There was significantly higher cumulative incidence of liver related outcome in cirrhotic patients with AMI compared with non-cirrhotic patients with AMI (HR 2.27, 95% CI 2.06-2.51, P?<?.001). And there was significantly higher all-cause mortality in cirrhotic patients with AMI compared with non-cirrhotic patients with AMI (HR 1.30, 95% CI 1.23-1.38, P?<?.001).In cirrhotic cohort with AMI, a decreased in coronary and cerebrovascular events were observed. However, these patients also had higher all-cause mortality due to adverse liver outcomes and bleeding.
