RÉSUMÉ
Acute-on-chronic liver failure (ACLF) is a global health problem. Little scientific evidence exists on its prevalence in autoimmune hepatitis. Treatment response and mortality outcomes have also been reported differently. The study was conducted to estimate the overall prevalence of ACLF among patients with autoimmune hepatitis (AIH) and determine the associated treatment response and mortality. We scrutinized wide literature in Scopus, PubMed, Embase, Web of Science, and Cochrane, and assessed published articles completely, studies performed and reported from around the globe, until December 07, 2023, according to the PROSPERO registered protocol (CRD42023412176). Studies (retrospective and prospective cohort study type) that stated the ACLF development among established AIH cases were considered. Features of the study, duration of follow-up, and numeric patient information were retrieved from the studies included. The research paper quality was checked for risk of bias. Random effect meta-analysis with metaregression and subsection scrutinies were performed with R. The main outcome was the collective prevalence of ACLF in the AIH patients, whereas treatment response and mortality in AIH-associated ACLF were secondary outcomes. Six studies were involved with confirmed diagnoses in 985 AIH patients for the data synthesis. The pooled prevalence of ACLF in the explored patients was 12% (95% CI: 8-17) ( P =0.01). Heterogeneity was found to be high in the present meta-analysis ( I2 =72%; P < 0.01). For the secondary endpoint analysis, the pooled prevalence of complete remission at 1-year follow-up was 71% (0.52; 0.85), and mortality from the ACLF-AIH patient population was 32% (95% CI: 18-50). Sensitivity analysis showed no influence on the overall estimations of the pooled prevalence of ACLF by omitting studies one by one. One in 10 AIH patients likely present with ACLF. The response to treatment is seen in two-thirds of patients, and mortality is high.

BACKGROUND: Empirical use of pharmacogenetic test(PGT) is advocated for many drugs, and resource-rich setting hospitals are using the same commonly. The clinical translation of pharmacogenetic tests in terms of cost and clinical utility is yet to be examined in hospitals of low middle income countries (LMICs). AIM: The present study assessed the clinical utility of PGT by comparing the pharmacogenetically(PGT) guided- versus standard of care(SOC)- warfarin therapy, including the health economics of the two warfarin therapies. METHODS: An open-label, randomized, controlled clinical trial recruited warfarin-receiving patients in pharmacogenetically(PGT) guided- versus standard of care(SOC)- study arms. Pharmacogenetic analysis of CYP2C9*2(rs1799853), CYP2C9*3(rs1057910) and VKORC1(rs9923231) was performed for patients recruited to the PGT-guided arm. PT(Prothrombin Time)-INR(international normalized ratio) testing and dose titrations were allowed as per routine clinical practice. The primary endpoint was the percent time spent in the therapeutic INR range(TTR) during the 90-day observation period. Secondary endpoints were time to reach therapeutic INR(TRT), the proportion of adverse events, and economic comparison between two modes of therapy in a Markov model built for the commonest warfarin indication- atrial fibrillation. RESULTS: The study enrolled 168 patients, 84 in each arm. Per-protocol analysis showed a significantly high median time spent in therapeutic INR in the genotype-guided arm(42.85%; CI 21.4-66.75) as compared to the SOC arm(8.8%; CI 0-27.2)(p < 0.00001). The TRT was less in the PG-guided warfarin dosing group than the standard-of-care dosing warfarin group (17.85 vs. 33.92 days) (p = 0.002). Bleeding and thromboembolic events were similar in the two study groups. Lifetime expenditure was â¹1,26,830 in the PGT arm compared to â¹1,17,907 in the SOC arm. The QALY gain did not differ in the two groups(3.9 vs. 3.65). Compared to SOC, the incremental cost-utility ratio was â¹35,962 per QALY gain with PGT test opting. In deterministic and probabilistic sensitivity analysis, the base case results were found to be insensitive to the variation in model parameters. In the cost-effectiveness-acceptability curve analysis, a 90% probability of cost-effectiveness was reached at a willingness-to-pay(WTP) of â¹ 71,630 well below one time GDP threshold of WTP used. CONCLUSION: Clinical efficacy and the cost-effectiveness of the warfarin pharmacogenetic test suggest its routine use as a point of care investigation for patient care in LMICs.

Though the chronic lymphocytic leukaemia (CLL) management options in India are still limited compared to the novel drug options in resource-rich settings, the availability of less costly generics and the government health insurance scheme has enabled many patients to access the newer drugs in India. The current study compared the cost-effectiveness and cost-utility of existing initial management options for the progression-free survival (PFS) time horizon from the patient's perspective. A two-health-state, PFS and progressive disease, Markov model was assumed for three regimens (generics): ibrutinib monotherapy, bendamustine-rituximab (B-R), and rituximab-chlorambucil (RClb) used as the frontline treatment of CLL patients in India. All costs, utilization of services, and consequences data during the PFS period were collected from interviewing patients during follow-up visits. The transition probability (TP) and average PFS information were obtained from landmark published studies. EQ-5D-5L questionnaires were utilized to assess the quality of life (QoL). Quality-adjusted life years (QALY) were measured during the PFS period. The incremental cost-effectiveness ratio (ICER) and incremental cost-utility ratio (ICUR) were studied. Upon analysis, the entire monetary expense during the PFS time was â¹1581964 with ibrutinib, â¹171434 with B-R, and â¹91997 with RClb treatment arm. Pooled PFS and QALY gain was 10.33 and 8.28 years for ibrutinib, 4.08 and 3.53 years for the B-R regimen, and 1.33 and 1.23 years in RClb arms, respectively. Ibrutinib's ICER and ICUR were â¹214587.32 per PFS year gain and â¹282384.86 per QALY gain when assessed against the B-R regimen. Ibrutinib also performed better in ICER and ICUR against the RClb arm with â¹157014.29 per PFS year gain and â¹200413.6 per QALY gain. In conclusion, generic ibrutinib is a cost-effective initial line of management compared to other commonly used treatment regimes in resource-limited settings.

AIM: To compare the relative effects of different dosages of sodium-glucose cotransport inhibitors (SGLT2i) for renoprotection in Type 2 diabetes mellitus. METHODS: The study searched different databases (PubMed, Embase, Scopus, and Web of Science) for studies comparing dose-dependent renoprotective efficacy defined as a decline in eGFR with the different "-flozins namely Empagliflozin, Canagliflozin, Dapagliflozin, Ertugliflozin, Ipragliflozin, Luseogliflozin, Remogliflozin and Sotagliflozin. The studies were compared with the Bayesian approach of network meta-analysis coupled with the random-effect model using the Cochrane risk of bias tool (RoB 2.0), and the surface under the cumulative ranking curve (SUCRA) score was allotted to each dosage of different SGLT-2i. RESULTS: A total of 43,434 citations were identified, out of which forty-five randomized trials with 48,067 patients, mentioning the flozin dose and eGFR as an endpoint, were found to be eligible for further analysis. The median duration of the follow-up in the trials was 12 months (IQR 5.5-16 months). Canagliflozin 100 mg demonstrated distinct eGFR benefit with an odds ratio of 2.3 (CI 0.72-3.9) compared to placebo. A statistically non-significant eGFR benefit was observed with all other "-flozins." Canagliflozin 100 mg drug dose category showed the highest sucra rank probability score of 93%, followed by the Canagliflozin 300 mg and Dapagliflozin 5 mg with sucra rank probability scores of 69% and 65%, respectively. The Flozin-dose assessment against eGFR was similar to the albumin-creatinine ratios as the secondary endpoint in the SUCRA ranking. CONCLUSION: The renoprotective efficacy of SGLT2i is independent of the incremental doses suggesting lower doses may suffice for renal outcomes.
