Societal costs and survival of patients with biopsy-verified non-alcoholic steatohepatitis: Danish nationwide register-based study.

INTRODUCTION AND OBJECTIVES: Studies on the societal burden of patients with biopsy-confirmed non-alcoholic fatty liver disease (NAFLD) are sparse. This study examined this question, comparing NAFLD with matched reference groups. MATERIALS AND METHODS: Nationwide Danish healthcare registers were used to include all patients (≥18 years) diagnosed with biopsy-verified NAFLD (1997-2021). Patients were classified as having simple steatosis or non-alcoholic steatohepatitis (NASH) with or without cirrhosis, and all matched with liver-disease free reference groups. Healthcare costs and labour market outcomes were compared from 5 years before to 11 years after diagnosis. Patients were followed for 25 years to analyse risk of disability insurance and death. RESULTS: 3,712 patients with biopsy-verified NASH (n = 1,030), simple steatosis (n = 1,540) or cirrhosis (n = 1,142) were identified. The average total costs in the year leading up to diagnosis was 4.1-fold higher for NASH patients than the reference group (EUR 6,318), 6.2-fold higher for cirrhosis patients and 3.1-fold higher for simple steatosis patients. In NASH, outpatient hospital contacts were responsible for 49 % of the excess costs (EUR 3,121). NASH patients had statistically significantly lower income than their reference group as early as five years before diagnosis until nine years after diagnosis, and markedly higher risk of becoming disability insurance recipients (HR: 4.37; 95 % CI: 3.17-6.02) and of death (HR: 2.42; 95 % CI: 1.80-3.25). CONCLUSIONS: NASH, simple steatosis and cirrhosis are all associated with substantial costs for the individual and the society with excess healthcare costs and poorer labour market outcomes.

Antibiotic-free vaginal microbiota transplant with donor engraftment, dysbiosis resolution and live birth after recurrent pregnancy loss: a proof of concept case study.

Background: Vaginal dysbiosis covers imbalances in the vaginal microbiota, defined by altered composition of bacteria, viruses, and fungi and is associated with euploid pregnancy losses, premature birth, infertility, or bacterial vaginosis. A large proportion of women who have vaginal dysbiosis do not experience any symptoms. Antibiotics are the traditional treatment, recently combined with local probiotics in some cases. Vaginal Microbiota Transplantation (VMT) with eubiotic vaginal bacterial microbiota after antibiotic eradication of pathogens has successfully been performed in a case study with five patients, but no VMT has been performed without the use of antibiotics. Methods: This is a proof of concept case study. The patient was found to have vaginal dysbiosis at the RPL clinic at Copenhagen University Hospital Hvidovre, Denmark on the 23rd of June 2021. She was offered and accepted to receive experimental treatment in the form of a VMT as a compassionate use case. VMT is the transfer of cervicovaginal secretions (CVS) from a healthy donor with a Lactobacillus-dominant vaginal microbiome to a recipient with a dysbiotic vaginal microbiome. CVS is a mixture of e.g., mucus, bacteria, metabolites present in the vaginal canal. Potential donors were thoroughly screened for the absence of STIs, and the most suitable donor sample for the specific patient in this study was determined via an in vitro microbiome competition assay. Findings: A 30-year-old patient with one livebirth and a complicated pregnancy history of two stillbirths and 1 s trimester pregnancy loss in gestational weeks 27 (2019), 17 (2020) and 23 (2020) respectively with complaints of vaginal irritation and discharge that had aggravated in all her pregnancies. Her vaginal microbiome composition showed a 90% dominance of Gardnerella spp. After one VMT there was a complete shift in microbiome composition to 81.2% L. crispatus and 9% L. jensenii with a concurrent resolvement of vaginal symptoms. Single nucleotide polymorphism-analysis confirmed her microbiome to be of donor origin and it remain stable now 1.5 years after the VMT. Five months after the VMT she became pregnant and has successfully delivered a healthy baby at term. Interpretation: Here we report a successful VMT with confirmed donor strain engraftment followed by a successful pregnancy and delivery after a series of late pregnancy losses/stillbirths. Findings suggest that VMT is a potential treatment for severe vaginal dysbiosis. Further, larger studies are required. Funding: The study was partially funded (i.e., analysis costs) by Freya Biosciences Aps, Fruebjergvej, 2100 Copenhagen, Denmark.

Liraglutide versus sitagliptin for patients with type 2 diabetes who did not have adequate glycaemic control with metformin: a 26-week, randomised, parallel-group, open-label trial.

BACKGROUND: Agonists of the glucagon-like peptide-1 (GLP-1) receptor provide pharmacological levels of GLP-1 activity, whereas dipeptidyl peptidase-4 (DPP-4) inhibitors increase concentrations of endogenous GLP-1 and glucose-dependent insulinotropic polypeptide. We aimed to assess the efficacy and safety of the human GLP-1 analogue liraglutide versus the DPP-4 inhibitor sitagliptin, as adjunct treatments to metformin, in individuals with type 2 diabetes who did not achieve adequate glycaemic control with metformin alone. METHODS: In this parallel-group, open-label trial, participants (aged 18-80 years) with type 2 diabetes mellitus who had inadequate glycaemic control (glycosylated haemoglobin [HbA(1c)] 7.5-10.0%) on metformin (>or=1500 mg daily for >or=3 months) were enrolled and treated at office-based sites in Europe, the USA, and Canada. Participants were randomly allocated to receive 26 weeks' treatment with 1.2 mg (n=225) or 1.8 mg (n=221) subcutaneous liraglutide once daily, or 100 mg oral sitagliptin once daily (n=219). The primary endpoint was change in HbA(1c) from baseline to week 26. The efficacy of liraglutide versus sitagliptin was assessed hierarchically by a non-inferiority comparison, with a margin of 0.4%, followed by a superiority comparison. Analyses were done on the full analysis set with missing values imputed by last observation carried forward; seven patients assigned to liraglutide did not receive treatment and thus did not meet criteria for inclusion in the full analysis set. This trial is registered with ClinicalTrials.gov, number NCT00700817. FINDINGS: Greater lowering of mean HbA(1c) (8.5% at baseline) was achieved with 1.8 mg liraglutide (-1.50%, 95% CI -1.63 to -1.37, n=218) and 1.2 mg liraglutide (-1.24%, -1.37 to -1.11, n=221) than with sitagliptin (-0.90%, -1.03 to -0.77, n=219). Estimated mean treatment differences for liraglutide versus sitagliptin were -0.60% (95% CI -0.77 to -0.43, p<0.0001) for 1.8 mg and -0.34% (-0.51 to -0.16, p<0.0001) for 1.2 mg liraglutide. Nausea was more common with liraglutide (59 [27%] patients on 1.8 mg; 46 [21%] on 1.2 mg) than with sitagliptin (10 [5%]). Minor hypoglycaemia was recorded in about 5% of participants in each treatment group. INTERPRETATION: Liraglutide was superior to sitagliptin for reduction of HbA(1c), and was well tolerated with minimum risk of hypoglycaemia. These findings support the use of liraglutide as an effective GLP-1 agent to add to metformin. FUNDING: Novo Nordisk.

Effects of Liraglutide on Cardiovascular Outcomes in Patients With Diabetes With or Without Heart Failure.

BACKGROUND: More data regarding effects of glucagon-like peptide-1 receptor agonists in patients with type 2 diabetes (T2D) and heart failure (HF) are required. OBJECTIVES: The purpose of this study was to investigate the effects of liraglutide on cardiovascular events and mortality in LEADER (Liraglutide Effect and Action in Diabetes: Evaluation of Cardiovascular Outcome Results) participants, by HF history. METHODS: In the multinational, double-blind, randomized LEADER trial, 9,340 patients with T2D and high cardiovascular risk were assigned 1:1 to liraglutide (1.8 mg daily or maximum tolerated dose up to 1.8 mg daily) or placebo plus standard care, and followed for 3.5 to 5 years. New York Heart Association (NYHA) functional class IV HF was an exclusion criterion. The primary composite major adverse cardiovascular events outcome was time to first occurrence of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke. Post hoc Cox regression analyses of outcomes by baseline HF history were conducted. RESULTS: At baseline, 18% of patients had a history of NYHA functional class I to III HF (liraglutide: n = 835 of 4,668; placebo: n = 832 of 4,672). Effects of liraglutide versus placebo on major adverse cardiovascular events were consistent in patients with (hazard ratio [HR]: 0.81 [95% confidence interval (CI): 0.65 to 1.02]) and without (HR: 0.88 [95% CI: 0.78 to 1.00]) a history of HF (p interaction = 0.53). In both subgroups, fewer deaths were observed with liraglutide (HR: 0.89 [95% CI: 0.70 to 1.14] with HF; HR: 0.83 [95% CI: 0.70 to 0.97] without HF; p interaction = 0.63) versus placebo. No increased risk of HF hospitalization was observed with liraglutide, regardless of HF history (HR: 0.98 [95% CI: 0.75 to 1.28] with HF; HR: 0.78 [95% CI: 0.61 to 1.00] without HF; p interaction = 0.22). Effects of liraglutide on the composite of HF hospitalization or cardiovascular death were consistent in patients with (HR: 0.92 [95% CI: 0.74 to 1.15]) and without (HR: 0.77 [95% CI: 0.65 to 0.91]) a history of HF (p interaction = 0.19). CONCLUSIONS: Based on these findings, liraglutide should be considered suitable for patients with T2D with or without a history of NYHA functional class I to III HF.

Estrogen receptor alpha and beta polymorphisms: is there an association with bone mineral density, plasma lipids, and response to postmenopausal hormone therapy?

OBJECTIVE AND DESIGN: A cross-sectional segregation analysis of polymorphisms in the estrogen receptor (ER) genes (Pvull and Xbal in ERalpha, and Alul in ERAbeta with bone mineral density in the lumbar spine and forearm and with lipid profile was performed in 1098 postmenopausal women. Additionally, in a subpopulation of 280 women, who completed 1 year of treatment with estrogen plus progestin, the association between genotypes and the response to treatment in both plasma lipids and bone was investigated. In another untreated subpopulation of 443 women, genotype influence on the prevalence of vertebral fractures and on annual rate of bone loss during a mean follow-up period of 11 years was estimated. RESULTS: Baseline plasma lipids, bone mineral density, annual rate of bone loss and prevalence of spinal fractures were not significantly associated with polymorphisms in the ERbeta gene. The ERA polymorphism was significantly associated with bone loss from the distal forearm (P = 0.04) but not with bone loss from the spine. After 1 year of treatment with hormone therapy there was also a significant association between the ERbeta polymorphism and the response in total cholesterol (P = 0.02); while the ERalpha gene polymorphisms did not significantly influence the response to hormone therapy. CONCLUSIONS: In a large white population of postmenopausal women, ERalpha gene polymorphisms were not associated with bone mineral density or lipid profile at baseline or after hormone therapy. Conversely, the ERbeta genotype appeared to segregate with bone loss from the forearm and to modulate the decrease in total cholesterol during hormone therapy.

Shortened life span, bradycardia, and hypotension in mice with targeted expression of an Igf2 transgene in smooth muscle cells.

IGF2 is known to affect the normal development and pathology of the cardiovascular system. We previously created mutant mice with targeted expression of an Igf2 transgene in the smooth muscle cells and showed that these mice spontaneously develop aortic intimal cushions. In the present work, we provide a general description of the phenotype of two independent lines of heterozygous transgenics. These mice showed organomegaly and a shortened life span. The latter trait was stronger in the line with a relatively more marked organomegaly and more pronounced in males than females in both lines. Postmortem histology revealed gross abnormalities of the cardiac architecture, suggesting that transgenic mice may accumulate lethal cardiovascular defects. Accordingly, apparently normal transgenic mice had mild cardiomegaly, an enlarged left ventricle, bradycardia, and hypotension. These observations are discussed in the light of the proposed therapeutic use of IGF2 in human cardiac diseases.

Associated response in bone and lipids during hormone replacement therapy.

OBJECTIVE: In postmenopausal women, we investigated if the response in bone mineral density (BMD) was associated with the response in the atherogenic lipid profile during hormone replacement therapy. METHODS: We performed an exploratory, post-hoc analysis of data from a prospective double-blind placebo-controlled trial. Healthy postmenopausal women were randomised into five groups, each receiving different combinations of 17 beta-estradiol and gestodene or placebo. A total of 133 women completed the study. The study period was 3 years. The response in bone mass was expressed as the percentage change in BMD from baseline calculated by linear regression from semi-annual measurements. The change in lipid profile was evaluated as the average of three mid-cycle and end-cycle values in percentage from baseline in order to account for cyclic changes during sequential hormone therapy. RESULTS: A significant correlation between the increase in BMD of the spine and hip and forearm with the decrease in serum low density lipoprotein (LDL) and cholesterol was found. Additionally, the decrease in atherogenic lipids correlated significantly with the response in biochemical bone markers for resorption and formation. CONCLUSION: In conclusion, our study shows that it is the same women who have a favourable response in BMD as in the lipid-profile during hormone replacement therapy (HRT). The association is most likely driven by a common response in FSH to exogenous estradiol therapy. This indicates that common denominators for the response to HRT exist. Further studies are needed to explore and identify such predictors.
