- BACKGROUND: In young men, high body mass index (BMI) has been linked to liver disease later in life, but it is unclear if this also applies to women.AIM: To study the association between BMI early in life and development of liver disease later in life in women.METHODS: We obtained data on early pregnancy BMI from 1 139 458 Swedish women between 1992 and 2015. National registers were used to ascertain incident severe liver disease, defined as cirrhosis, decompensated liver disease (hepatocellular carcinoma, oesophageal varices, hepatorenal syndrome or hepatic encephalopathy) or liver failure. A Cox regression model was used to investigate associations of BMI with incident severe liver disease adjusting for maternal age, calendar year, country of birth, smoking, civil status and education.RESULTS: (95% CI 1.02-1.05). A diagnosis of diabetes was associated with an increased risk of severe liver disease independent of baseline BMI.CONCLUSION: A high BMI early in life in women is associated with a dose-dependent, increased risk for future severe liver disease.

- BACKGROUND & AIMS: Data on healthcare resource use and costs associated with nonalcoholic fatty liver disease (NAFLD) in clinical practice are lacking. We compared real-life healthcare costs of patients with NAFLD to matched controls. METHODS: We performed a retrospective study of 646 patients with biopsy-proven NAFLD in Sweden from 1971 through 2009. Each patient was matched for age, sex, and county of residence with 10 persons from the general population (controls). We retrieved all healthcare contacts through Dec 31, 2014 from national registers. Unit costs were assigned to arrive at a total healthcare cost (in USD [$]) per study subject. RESULTS: During a mean follow-up of 19.9 years, we recorded a mean of 0.27 hospitalizations per year for patients with NAFLD vs 0.16 for controls (P <.001). This corresponded to an incremental cost of $635 per year for patients with NAFLD. Patients with NAFLD had a higher mean use of outpatient care visits: 1.46 contacts per year compared with 0.86 per year in controls, corresponding to $255 in additional costs (P <.001). Total costs incurred by patients with stage 3-4 fibrosis were higher than by patients with fibrosis stage 0-2 (mean annual costs, $4397 vs $629). Cumulative costs were higher for all stages of fibrosis compared to controls. CONCLUSIONS: Healthcare costs are nearly twice as high in patients with NAFLD than in matched controls. This is mostly attributable to higher costs for hospitalizations, but also to more outpatient visits. Patients with advanced fibrosis had the highest costs.

Tidskriftsartikel (refereegranskat)abstract
- Background and aim: Moderate alcohol consumption has been associated with a lower risk of disease severity in non-alcoholic fatty liver disease (NAFLD). It is unclear if this reflects current or lifetime drinking, or can be attributed to confounders such as diet and exercise. We evaluated the impact of lifetime alcohol consumption on fibrosis severity in NAFLD. Methods: We prospectively enrolled 120 subjects with biopsy-proven NAFLD and through detailed questionnaires examined lifetime alcohol consumption, diet and physical activity. Main outcome measures were odds ratios (OR) for fibrosis stage, calculated through ordinal regression after adjustment for body mass index, diabetes mellitus type 2, smoking and age at biopsy. A biomarker for recent alcohol consumption, phosphatidyl ethanol (PEth) was sampled. Results: An increase in median weekly alcohol consumption to a maximum of 13 drinks per week was associated with lower fibrosis stage (adjusted OR for each incremental unit, 0.86; 95% CI, 0.76-0.97; p = .017). The lowest risk for fibrosis was found with the lowest odds seen in the top quartile of alcohol consumption (aOR 0.23; 95% CI 0.08-0.66; p = .006). Adding soft drink and coffee consumptions, and physical activity to the model did not change the estimates. Subjects with PEth >= 0.3 mu mol/L had higher ORs for a higher fibrosis stage (aOR 2.77; 95% CI 1.01-7.59; p = .047). Conclusion: Lifetime alcohol consumption with up to 13 units per week is associated with lower fibrosis stage in NAFLD. Elevated PEth is associated with higher stages of fibrosis.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND & AIMS: The burden of diverticular disease on society is high and is increasing with an aging population. It is therefore important to identify risk factors for disease development or progression. Many lifestyle behaviors during adolescence affect risk for later disease. We searched for adolescent lifestyle factors that affect risk of diverticular disease later in life. METHODS: We performed a retrospective analysis of data from 43,772 men (age, 18-20 y) conscripted to military service in Sweden from 1969 through 1970, with a follow-up period of 39 years. All conscripts underwent an extensive mental and physical health examination and completed questionnaires covering alcohol consumption, smoking, and use of recreational drugs; cardiovascular fitness was assessed using an ergometer cycle at the time of conscription. Outcome data were collected from national registers to identify discharge diagnoses of diverticular disease until the end of 2009. We performed Cox regression analysis to determine whether body mass index, cardiovascular fitness, smoking, use of recreational drugs, alcohol consumption, and risky use of alcohol, at time of conscription are independent risk factors for development of diverticular disease. RESULTS: Overweight and obese men had a 2-fold increased risk of diverticular disease compared to normal-weight men (hazard ratio, 2.00; P < .001). A high level of cardiovascular fitness was associated with a reduced risk of diverticular disease requiring hospitalization (P = .009). Smoking (P = .003), but not use of recreational drugs (P = .11), was associated with an increased risk of diverticular disease requiring hospitalization. Risky use of alcohol, but not alcohol consumption per se, was associated with a 43% increase in risk of diverticular disease requiring hospitalization (P = .007). CONCLUSIONS: In a retrospective analysis of data from 43,772 men in Sweden, we associated being overweight or obese, a smoker, a high-risk user of alcohol, and/or having a low level of cardiovascular fitness in late adolescence with an increased risk of developing diverticular disease requiring hospitalization later in life. Improving lifestyle factors among adolescents might reduce the economic burden of diverticular disease decades later.

- Background: Obesity is a risk factor for colorectal cancer (CRC).Objective: The objective of this article is to investigate whether anthropometric measures reflecting visceral obesity are better predictors of CRC than body mass index (BMI).Methods: Data were analysed from the Malmo Diet and Cancer study in Sweden, comprising 16,669 women and 10,805 men (median age 56.6 and 59.1 years) followed for a median 21.5 years. Diagnoses of CRC were identified using Swedish national registers. Cox regression was used to test the associations of BMI, waist circumference (WC), waist-hip ratio, waist-to-height ratio, waist-to-hip-to-height ratio, A Body Shape Index (ABSI) and percentage body fat with the development of CRC adjusted for age, alcohol consumption, smoking, education and physical activity in men and women.Results: None of the measures were significantly associated with an increased risk for CRC in women. WC was the strongest predictor of colon cancer (CC) in men and the only measure that was independent of BMI. ABSI was the only measure significantly associated with the risk of rectal cancer in men.Conclusions: Visceral obesity, best expressed as WC, is a risk factor for CC in men but a poor predictive marker for CRC in women.

- Background and Aims Several genotypes associate with a worse histopathological profile in patients with non-alcoholic fatty liver disease (NAFLD). Whether genotypes impact long-term outcomes is unclear. We investigated the importance of PNPLA3, TM6SF2, MBOAT7 and GCKR genotype for the development of severe outcomes in NAFLD. Method DNA samples were collected from 546 patients with NAFLD. Advanced fibrosis was diagnosed by liver biopsy or elastography. Non-alcoholic steatohepatitis (NASH) was histologically defined. Additionally, 5396 controls matched for age, sex and municipality were identified from population-based registers. Events of severe liver disease and all-cause mortality were collected from national registries. Hazard ratios (HRs) adjusted for age, sex, body mass index and type 2 diabetes were estimated with Cox regression. Results In NAFLD, the G/G genotype of PNPLA3 was associated with a higher prevalence of NASH at baseline (odds ratio [OR] 3.67, 95% CI = 1.66-8.08), but not with advanced fibrosis (OR 1.81, 95% CI = 0.79-4.14). After up to 40 years of follow-up, the PNPLA3 G/G genotype was associated with a higher rate of severe liver disease (adjusted hazard ratio [aHR] 2.27, 95% CI = 1.15-4.47) compared with the C/C variant. NAFLD patients developed cirrhosis at a higher rate than controls (aHR 9.00, 95% CI = 6.85-11.83). The PNPLA3 G/G genotype accentuated this rate (aHR 23.32, 95% = CI 9.14-59.47). Overall mortality was not affected by any genetic variant. Conclusion The PNPLA3 G/G genotype is associated with an increased rate of cirrhosis in NAFLD. Our results suggest that assessment of the PNPLA3 genotype is of clinical relevance in patients with NAFLD to individualize monitoring and therapeutic strategies.

Tidskriftsartikel (refereegranskat)abstract
- Background: Prior studies suggest a link between metabolic dysfunction-associated steatotic liver disease (MASLD) and incident arrhythmias, including atrial fibrillation (AF). However, robust data are lacking from cohorts with liver histology, which remains the gold standard for staging MASLD severity.Methods: This population-based cohort included all Swedish adults with histologically-confirmed MASLD and without prior cardiac arrhythmias (1966-2016; n = 11,206). MASLD was defined from prospectively-recorded histopathology, and characterized as simple steatosis, non-fibrotic steatohepatitis (MASH), non-cirrhotic fibrosis, or cirrhosis. MASLD patients were matched to <= 5 controls without MASLD or arrhythmias, by age, sex, calendar year and county (n = 51,856). Using Cox proportional hazards modeling, we calculated multivariable-adjusted hazard ratios (aHRs) for incident arrhythmias (including AF, bradyarrhythmias, other supraventricular arrhythmias, ventricular arrhythmias/cardiac arrest).Results: Over a median follow-up of 10.8 years, incident arrhythmias were confirmed in 1351 MASLD patients (10.3/1000 person-years [PY]) and 6493 controls (8.7/1000PY; difference = 1.7/1000PY; aHR = 1.30, 95%CI 1.22-1.38), and MASLD patients had significantly higher rates of incident AF (difference = 0.9/1000PY; aHR = 1.26, 95%CI 1.18-1.35). Rates of both overall arrhythmias and AF were significantly elevated across all MASLD histological groups, particularly cirrhosis (differences, 8.5/1000PY and 5.3/1000PY, respectively). In secondary analyses, MASLD patients also had significantly higher rates of incident ventricular arrhythmias/cardiac arrest (aHR = 1.53, 95%CI 1.30-1.80), bradyarrhythmias (aHR = 1.26, 95%CI 1.06-1.48), and other supraventricular arrhythmias (aHR = 1.27, 95%CI 1.00-1.62), compared to controls.Conclusions: Compared to matched controls, patients with biopsy-confirmed MASLD had modest but significantly higher incidence of cardiac arrhythmias, including AF, bradyarrhythmias, other supraventricular arrhythmias and ventricular arrhythmias/cardiac arrest. Excess risk was observed across all stages of MASLD and was highest with cirrhosis.

- Background & Aims: High alcohol consumption is associated with an increased risk of severe liver disease. Current recommendations suggest it is safe for men to consume 30 grams of alcohol per day. We investigated the association between alcohol consumption early in life and later development of severe liver disease.Methods: We used data on alcohol consumption at conscription to military service from 43,296 men (18-20 years) in Sweden between 1969 and 1970. Outcomes were defined as incident diagnoses of severe liver disease from systematic national registration of clinical events until the end of 2009. A Cox regression model adjusted for body mass index, smoking, use of narcotics, cognitive ability and cardiovascular capacity was applied.Results: During a mean follow-up of 37.8 years, 383 men developed severe liver disease. Alcohol consumption was associated with an increased risk of development of severe liver disease in a dose-response pattern (adjusted hazard ratio for every one gram/day increase 1.02; 95% CI 1.01-1.02). No evidence of a threshold effect was found. Importantly, a clear trend pointed towards an increased risk of severe liver disease in men who consumed less than 30 grams of alcohol per day.Conclusion: Alcohol consumption in young men is associated with an increased risk of severe liver disease, up to 39 years later in life. The risk was dose-dependent, with no sign of a threshold effect. Current guidelines for safe alcohol intake in men might have to be revised.Lay summary: We investigated more than 43,000 Swedish men in their late teens enlisted for conscription in 1969–1970. After almost 40 years of follow-up, we found that alcohol consumption was a significant risk factor for developing severe liver disease, independent of confounders. This risk was dose-dependent, and was most pronounced in men consuming two drinks per day or more.

- BACKGROUND & AIMS: Noninvasive scoring systems are used to identify persons with advanced liver fibrosis. We investigated the ability of scoring systems to identify individuals in the general population at risk for future liver-related events. METHODS: We collected data from the Swedish Apolipoprotein Mortality Risk cohort on persons 35 to 79 years old who had blood samples collected from 1985 through 1996. We collected APRI (n = 127,302), BARD (n = 75,303), FIB-4 (n = 126,941), Forns (n = 122,419), and the nonalcoholic fatty liver disease (NAFLD) fibrosis scores (NFS, n = 13,160). We ascertained incident cases of cirrhosis or complications by linking Swedish health data registers. Cox regression was used to estimate hazard ratios (HRs) for severe liver disease at 5, 10, and a maximum follow-up time of 27 years. The predictive ability of the scores was evaluated using area under the receiver operating characteristic (AUROC) curve and C-statistics analyses. Our specific aims were to investigate the predictive capabilities of scoring systems for fatal and nonfatal liver disease, determine which scoring system has the highest level of accuracy, and investigate the predictive abilities of the scoring systems in persons with a higher probability of NAFLD at baseline. RESULTS: A similar proportion of individuals evaluated by each scoring system developed cirrhosis or complications thereof (1.0%-1.4%). The incidence of any outcome was increased in intermediate- and high-risk groups compared with low-risk groups, with HRs at 10 years in the high-risk group ranging from 1.67 for the BARD score to 45.9 for the APRI score. The predictive abilities of all scoring systems decreased with time and were higher in men. All scoring systems were more accurate in persons with risk factors for NAFLD at baseline, with AUROCs reaching 0.83. CONCLUSIONS: Higher scores from noninvasive scoring systems to evaluate fibrosis are associated with an increased risk of cirrhosis in a general population, but their predictive ability is modest. Performance was better when patients were followed for shorter time periods and in persons with a higher risk of NAFLD, with AUROC values reaching 0.83. New scoring systems are needed to evaluate risk of fibrosis in the general population and in primary care.
