The role of treatment of hepatitis C with direct-acting antiviral agents on glycaemic control in diabetic patients: An updated systematic review and meta-analysis. J Viral Hepat 2024. [PMID: 39046172 DOI: 10.1111/jvh.13984] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Revised: 05/25/2024] [Accepted: 07/16/2024] [Indexed: 07/25/2024]
Abstract
Recent studies suggested that successful clearance of chronic Hepatitis C Virus (HCV) by using direct-acting antiviral (DAA) agents could improve glycemic control in patients with diabetes; however, some studies failed to identify this benefit. We conducted a systematic review and meta-analysis to assess the impact of sustained virologic response (SVR) after treatment with DAA agents on glycemic control. Embase, Scopus and PubMed were searched through March 26th, 2023, for all studies evaluating whether eradication of HCV infection with DAAs is associated with an impact on glycemic control. Only studies with data on glycemic control, including haemoglobin A1c (HbA1c), fasting glucose, or Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), at least 12-week post-SVR were included. Sixteen studies met our eligibility criteria and were included in qualitative analysis. The mean HbA1c was 8.05% (95% CI: 7.79%-8.31%) before treatment and 7.19% (95% CI: 6.98%-7.39%) after treatment. There was a significant mean absolute reduction in HbA1c of 0.72% (95% CI: 0.52%-0.93%) with high heterogeneity between studies (I2 = 91.7%). The reduction in HbA1c remained significant in the subgroup analysis at 3 months follow up post SVR [0.74% (95% CI: 0.57%-0.91%)] and at least 6 months follow up [0.66% (95% CI: 0.23%-1.10%)]. We found a significant reduction in HbA1C after SVR in patients with type 2 diabetes mellitus, reflecting better glycemic control with HCV eradication. This data highlights an important extrahepatic benefit of HCV eradication.

Abstract
BACKGROUND AND STUDY AIMS Hepatitis C virus (HCV) impairs glucose homoestasis, thus influences its clinical picture and prognosis. This study aimed at evaluating Diabetes mellitus (DM) on Egyptian patients with chronic hepatitis C (CHC), and its impact on their virologic response when treated with directly acting antiviral (DAA) medications. PATIENTS AND METHODS Adult patients with CHC were divided into 2 groups; Diabetic patients, and Non diabetic patients serving as control group. All patients were subjected to thorough clinical evaluation, basic biochemical laboratory tests including fasting blood glucose/glycosylated haemoglobin (HbA1C), and virologic assay. They were treated with various combined DAAs, and were monitored during, at and after end of treatment. RESULTS Diabetic patients constituted 9.85 % of CHC, and had generally worse laboratory tests (significantly higher transaminases, platelet count, Fib4 and hepatic steatosis) than non diabetic patients, and a less sustained virologic response (SVR) (significantly in Sofosbuvir (SOF) + pegylated interferon (PegIFN) + ribavirin (RBV), SOF + RBV, SOF + daclatasvir (DAC)). Although DM did not play a significant influence on SVR, yet Fib4 and SOF + RBV + PEG-IFN were significant factors affecting SVR among diabetics, while female gender and viraemia were significant factors affecting SVR among non diabetics. Hepatic fibrosis and SOF/RBV significantly influenced SVR in both groups. CONCLUSIONS Diabetic patients with CHC have worse liver biochemical profile, yet DM per se did not influence the virologic response to DAAs, however, some factors played roles in affecting SVR among them.

Abstract
The cure of chronic hepatitis C infection has a major impact on the morbidity and mortality of infected patients. It is now clear that sustained virologic response improves overall survival and significantly reduces the risk of liver failure, fibrosis progression, need of liver transplantation, and incidence of hepatocellular carcinoma. Moreover, hepatitis C eradication improves a broad range of extrahepatic manifestations, such as dermatologic, neoplastic, cardiovascular, and endocrine, and improves quality of life.

Abstract
AIM To assess the effect of treating chronic hepatitis C virus (HCV) infection with direct acting antiviral drugs (DAAs) on glycemic control in patients with concomitant diabetes mellitus (DM). METHODS We performed a retrospective case-control study in a viral hepatitis ambulatory clinic in Shreveport, Louisiana, during the period 11/01/2014 to 12/31/2017. All the clinic patient ages 18 years and above with treatment-naïve/biopsy-proven chronic hepatitis C and DM (hemoglobin A1C level ≥ 6.5%) who were eligible for treatment were included in the study. Of 118 such patients, 59 were treated with oral DAAs for 8-12 weeks with the goal of achieving a sustained virologic response (SVR). A control group of 59 patients did not receive treatment for their hepatitis C and was followed in the clinic. Patients in the control group did not receive treatment either due to insurance issues or refusal of hepatitis C treatment. RESULTS Fifty-five of the 59 patients treated with DAAs (93%) achieved a SVR. Six months after treatment completion, their mean ± SEM HbA1C level had decreased by 1.1 ± 0.03% (P < 0.0001). Four of the 59 patients treated with DAAs did not achieve a SVR. Their mean HbA1C 6 months after treatment completion had increased by 0.8 ± 0.2%. Furthermore, there was no improvement in HbA1C levels over time in the untreated group (mean HbA1C increase, 0.2 ± 0.05%; P < 0.0001 vs. the treatment group, which had a mean HbA1C decrease of 0.9 ± 0.2%). CONCLUSION This controlled study demonstrated that treatment of chronic hepatitis C with DAAs results in statistically significant and meaningful reductions in hemoglobin A1C levels in patients with coexisting diabetic mellitus if a SVR is achieved.

Abstract
AIMS The effect of HCV eradication following the use of direct-acting antiviral drugs (DAAs) on the glyco-metabolic control is unknown. Through a meta-analysis of available clinical studies, we investigated whether eradication of HCV infection with interferon-free DAAs is associated with improved glyco-metabolic control in diabetic patients. METHODS We searched the PubMed, MEDLINE and Embase, up to 08th June 2018, for all studies evaluating whether eradication of HCV infection with DAAs is associated with changes in glycated haemoglobin (HbA1c) and fasting plasma glucose (FPG) levels from baseline in human subjects, without restrictions for study type and language. Data were independently extracted by two researchers using pre-specified forms. Random effects meta-analyses were conducted on HbA1c and FPG levels before/after HCV eradication. RESULTS We found a significant mean reduction in HbA1c levels of - 0.45% (95% CI - 0.60 to - 0.30%; P < 0.001) and in FPG levels of - 22.03 mg/dL (95% CI - 41.61 to - 2.44 mg/dL; P = 0.03), with high heterogeneity between studies (χ2 = 20.4, P < 0.001, I2 = 80% and χ2 = 35.8, P = 0.001, I2 = 94%, respectively). The number of available manuscripts did not allow conducting a meta-regression to elucidate the role of sustained virological response and other confounders in determining the effect of direct-acting antiviral agents on HbA1c reduction. CONCLUSIONS We found a significant improvement in glyco-metabolic control after HCV eradication (in terms of glycated haemoglobin and fasting plasma glucose levels reduction) following direct-acting antiviral treatment in patients with established diabetes, including a consequent positive impact on anti-diabetic therapies.

Abstract
The prevalence and mortality of diabetes mellitus and liver disease have risen in recent years. The liver plays an important role in glucose homeostasis, and various chronic liver diseases have a negative effect on glucose metabolism with the consequent emergence of diabetes. Some aspects related to chronic liver disease can affect diagnostic tools and the monitoring of diabetes and other glucose metabolism disorders, and clinicians must be aware of these limitations in their daily practice. In cirrhotic patients, fasting glucose may be normal in up until 23% of diabetes cases, and glycated hemoglobin provides falsely low results, especially in advanced cirrhosis. Similarly, the performance of alternative glucose monitoring tests, such as fructosamine, glycated albumin and 1,5-anhydroglucitol, also appears to be suboptimal in chronic liver disease. This review will examine the association between changes in glucose metabolism and various liver diseases as well as the particularities associated with the diagnosis and monitoring of diabetes in liver disease patients. Alternatives to routinely recommended tests will be discussed.

Abstract
Chronic HCV infection has emerged as a complex multifaceted disease with manifestations extending beyond the liver. HCV plays a direct role in glucose metabolism leading to both insulin resistance and type 2 diabetes. To evaluate the changes in the glycemic state following Sofosbuvir-based treatment regimens in diabetic HCV patients. Four hundred chronic hepatitis C patients who underwent Sofosbuvir-based treatment regimens were retrospectively screened. Sixty-five diabetic HCV patients only enrolled in our analysis. Baseline demographic and laboratory data were recorded. Pretreatment Transient elastography was performed. At 24-week post EOT (SVR24), Fasting Plasma glucose, and Hemoglobin A1c were re-evaluated and compared with baseline. All enrolled diabetic patients were responders. They showed statistically significant decline in Fasting Plasma glucose and Hemoglobin A1c values at SVR24. Whatever the degree of hepatic fibrosis, the level of Fasting Plasma glucose and Hemoglobin A1c decreased at SVR24 in comparison to baseline level. Fifty-one patients showed improvement in their Hemoglobin A1c values at SVR24 and this improvement was more likely to occur among patients with low Body mass index. The reduction in Fasting Plasma glucose >20 mg/dL (>1.1 mmol/L) and Hemoglobin A1c ≥0.5% was not associated with age, gender or hepatic fibrosis stage. Sofosbuvir-based regimens are a highly efficient antiviral therapy for diabetic chronic HCV patients resulted in improvement in Fasting Plasma glucose and Hemoglobin A1c.

Abstract
INTRODUCTION AND AIM The effect of the new direct acting antiviral drugs (DAAs) for chronic hepatitis C (HCV) on glycemic control is unknown. MATERIALS AND METHODS We conducted a retrospective cohort study of patients who were treated for chronic HCV with direct-acting antiviral medications at a single academic institution between May 2013 and April 2016. Univariate analysis was performed comparing subjects pre- and post-treatment. RESULTS One hundred seventy-five consecutive adult patients were treated for chronic HCV and met enrollment criteria. The majority (80.8%) were genotype 1 and overall cohort sustained virologic response at week 12 (SVR12) was 97.8%. Thirty-one (18.5%) had diabetes mellitus (DM); twenty-six had pre- and post-treatment HbA1c values. Of these, 76.9% were male and 61.5% had cirrhosis. Ninety-six percent were prescribed sofosbuvir-based therapy and all but one (96.8%) achieved SVR12. Three patients were started on treatment despite meeting the definition for poorly controlled DM (HbA1c > 9 mg/dL). There was no significant difference when comparing pre-treatment (7.36 mg/dL, 95% CI 6.55-8.16) to post-treatment HbA1c (7.11 mg/dL, 95% CI 6.34-7.88, p = 0.268). Thirty-one percent of subjects required dose escalation or the initiation of insulin based therapy during treatment. DISCUSSION Although chronic HCV is associated with exacerbation of insulin resistance, our results showed HbA1c to be unaffected by eradication of chronic HCV with DAA in diabetic patients with and without cirrhosis. Paradoxically, almost 1/3 of patients required escalation of anti-diabetic therapy during treatment. Long-term studies are warranted to understand the relationship between HCV viral eradication and insulin metabolism.

Abstract
Patients with hematologic malignancies are at high risk for hyperglycemia due to factors such as frequent exposure to glucocorticoids, immunosuppressants, total parenteral nutrition, and medical stress. Hyperglycemia in these patients has been associated with poor outcomes including increased risk of infection, organ dysfunction, durability of remission, graft-versus-host disease, and mortality. However, the appropriate glucose targets are not well established, and there are few prospective data assessing whether glucose control improves outcomes. HbA1c should be interpreted with caution in patients with hematologic malignancies, due to inaccuracies imposed by disordered hematopoiesis and frequent transfusions, and short-term perturbations imposed by acute illness or medications. Management of diabetes or glucocorticoid-induced hyperglycemia in the hospital generally requires insulin therapy, which is tailored based upon nutritional needs, baseline glucose control, and concomitant factors such as type and dose of glucocorticoid administration. Close follow-up and adjustment of therapy, ideally with the assistance of patient self-titration algorithms, is required after discharge. Patients are at increased long-term risk for developing diabetes and therefore should undergo regular screening.

Abstract
Since the beginning of clinical use in the 1970s, hemoglobin A1c (A1c) has become the standard tool for monitoring glycemic control in patients with diabetes. The role of the A1c test was broadened in 2010, when the American Diabetes Association added A1c as a diagnostic criterion for diabetes. Because of hemoglobin A1c's integral role in diagnosis and treatment, it is important to recognize clinical scenarios and interfering factors that yield false results. The purpose of this review is to describe the A1c measurement, outline clinical scenarios or factors that may yield false results, and describe alternative laboratory biomarkers.

Abstract
HbA1c has become the gold standard for monitoring glycemic control in patients with diabetes mellitus. The use of this test has been expanded to diagnose and screen for diabetes mellitus with the endorsement of influential diabetes societies and the World Health Organization. The literature on the use of HbA1c for the diagnosis and screening of diabetes mellitus was critically examined. There is substantial recent literature on this topic with strong advocates for the use of HbA1c to diagnose and screen for diabetes and equally strong detractors for its use. Advocates of the use of HbA1c cite challenges in respect of patient compliance and the analysis of glucose and inconsistency of diagnosis with glucose-based diabetes diagnosis with the elimination or reduction in these challenges in HbA1c-based diagnosis. Detractors of its use cite increased cost, concerns about the availability of HbA1c testing, and the influence of demographic and clinical factors on HbA1c results that make the use of a single-threshold values questionable for different ethnic and age groups. Despite the recommendation of many international diabetes societies that HbA1c be used for screening and diagnosis of diabetes mellitus, there is a wide divergence of opinion on this use.

Abstract
BACKGROUND Among individuals without diabetes, elevated hemoglobin A1c (HbA1c) has been associated with increased morbidity and mortality, but the literature is sparse regarding the prognostic importance of low HbA1c. METHODS AND RESULTS National Health and Nutrition Examination Survey III (NHANES III) participants, 20 years and older, were followed up to 12 years (median follow-up, 8.8 years) for all-cause mortality. Cox proportional hazards regression was used to calculate hazard ratios (HR) and 95% confidence intervals (CI) for the association between HbA1c levels and all-cause mortality for 14 099 participants without diabetes. There were 1825 deaths during the follow-up period. Participants with a low HbA1c (<4.0%) had the highest levels of mean red blood cell volume, ferritin, and liver enzymes and the lowest levels of mean total cholesterol and diastolic blood pressure compared with their counterparts with HbA1c levels between 4.0% and 6.4%. An HbA1c <4.0% versus 5.0% to 5.4% was associated with an increased risk of all-cause mortality (HR, 3.73; 95% CI, 1.45 to 9.63) after adjustment for age, race-ethnicity, and sex. This association was attenuated but remained statistically significant after further multivariable adjustment for lifestyle, cardiovascular factors, metabolic factors, red blood cell indices, iron storage indices, and liver function indices (HR, 2.90; 95% CI, 1.25 to 6.76). CONCLUSIONS In this nationally representative cohort, low HbA1c was associated with increased all-cause mortality among US adults without diabetes. Additional research is needed to confirm these results and identify potential mechanisms that may be underlying this association.
