Onset of type 1 diabetes mellitus during peginterferon alpha-2b plus ribavirin treatment for chronic hepatitis C

Characteristics of Interferon-Associated Diabetes Mellitus in Past 30 Years: A Review

Interferon (IFN) is a broad-spectrum antiviral agent that activates cell surface receptors and causes cells to produce antiviral proteins, inhibiting viral replication. Interferon use has long been associated with diabetes. The PubMed database was searched for articles related to diabetes and interferon from March 30, 2020. Patients were divided into type 1 diabetes group and type 2 diabetes group. We reviewed the relevant literature to compare interferon-associated T1D and interferon-associated T2D differences. Interferon treatment shortened the incubation period of T2D and changed the original T2D to T1D. The onset of interferon-associated T1D required longer periods of IFN treatment than interferon-associated T2D, and the interferon-associated T1D group had higher GADA positive rates, lower BMI, lower fasting blood glucose, and greater insulin dependence (p<0.05). More patients in the T1D group were positive for HLA-DRB1*04, DRB1*03, DRB1*09, DRB1*14, HLA-DQB1*04, HLA-DQB1*02, HLA-DQB1*03, and HLA-DQB1*05. The combined detection of GAD antibodies and HLA alleles may be an effective method to predict the incidence of T1D after IFN treatment.

Direct-acting antiviral treatment in real world patients with hepatitis C not associated with psychiatric side effects: a prospective observational study

BACKGROUND

Treatment of Hepatitis C virus (HCV) infection has evolved from interferon (IFN)-based treatments to direct-acting antivirals (DAAs). Patients with HCV have an elevated psychiatric morbidity (including substance abuse) and patients with such comorbidity have often been excluded from treatment with IFN. To date, little is known about psychiatric adverse effects of DAA-based regimens. We therefore aimed to study the psychiatric side effects of new IFN-free treatment for HCV (including depressive symptoms and sleep) in real world patients also including those with a history of psychiatric diagnosis, substance abuse or drug dependence.

METHODS

Consecutive patients were monitored during treatment with three of the latest DAA agents (sofosbuvir, simeprevir and daclatasvir). Repeated expert psychiatric assessments from baseline to 12 weeks post-treatment were performed with the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) clinical version and the self-report versions of the Montgomery Åsberg Depression Rating Scale (MADRS-S) and the Pittsburgh Sleep Quality Index (PSQI). Friedman's test was performed to calculate differences in the MADRS-S and PSQI over time. In a post-hoc analysis Wilcoxon's test was used to compare baseline depressive symptoms with those at post-treatment. Spearman's rank correlation test was conducted in another post-hoc analysis to evaluate the correlation between symptoms of depression and HCV viral load at baseline.

RESULTS

At baseline, 15/17 patients (88%) had a history of any psychiatric diagnosis; 11 (65%) had a history of substance abuse or dependence; and 11 (65%) had previously been treated with IFN and six of those had experienced psychiatric side effects. There was no correlation between depressive symptoms and HCV viral load at baseline. Symptoms of depression did not increase during DAA treatment and were lower 12 weeks post-treatment compared with baseline: MADRS-S 10.7 vs. 8.3 (p = 0.01). This observation held when excluding patients taking antidepressant medication. Sleep quality did not significantly change during treatment. Adherence to treatment was estimated to 95% and sustained virological response was 88%.

CONCLUSIONS

Despite high psychiatric morbidity, including previous substance abuse, patients successfully completed DAA treatment without increasing depressive symptoms or sleep disturbance. Symptoms of depression were significantly reduced 12 weeks after DAA treatment.

Recombinant Interferon Alpha-2b is a High-Affinity Antigen for Type 1 Diabetes Autoantibodies

OBJECTIVES

Type 1 diabetes results from T-cell-mediated destruction of the beta cells of the pancreas and is associated with several autoimmune phenomena. Many studies have suggested the involvement of interferon alpha (IFN α) in the development of type 1 diabetes, but the exact mechanism remains unclear. In this study, the binding of type 1 diabetes antibodies with recombinant interferon alpha-2b (hrIFN α-2b), their gene (cIFN α-2b gene) and commercially available interferon α-2b (IFN α-2b) were assessed. Furthermore, we also sought to use anti-hrIFN α-2b antibodies as a probe for the estimation of plasma IFN α in patients with type 1 diabetes.

METHODS

The binding specificity of antibodies was analyzed by direct binding, inhibition ELISA and quantitative precipitin titration in 45 patients with type 1 diabetes and 30 control subjects. Competition ELISA was also used to estimate INF α in the serum of patients with type 1 diabetes.

RESULTS

Antibodies from type 1 diabetes sera, purified in a protein A-agarose matrix, exhibited greater recognition of hrIFN α-2b than IFN α-2b (p<0.05) and cIFN α-2b gene (p<0.001). The relative affinity of type 1 diabetes antibodies for the hrIFN α-2b, IFN α-2b and cIFN α-2b genes was found to be 1.34×10^-7, 1.28×10^-6 and 1.13×10^-6, respectively. The concentration of plasma INF α evaluated by induced antibodies was found to be significantly higher than in controls (p<0.05).

CONCLUSIONS

High binding of hrIFN α-2b with IgG from patients with type 1 diabetes might suggest involvement of hrIFN α-2b in type 1 diabetes, especially as an antigenic agent. Anti-hrIFN α-2b antibodies were shown to be good probes for estimation of plasma INF α in patients with type 1 diabetes.

Pegylated interferon plus ribavirin therapy improves pancreatic β-cell function in chronic hepatitis C patients

BACKGROUND/AIMS

Pretreatment insulin resistance (IR) is associated with treatment response to peginterferon plus ribavirin (PegIFN/RBV) combination therapy in chronic hepatitis C (CHC) infection. However, the impact of PegIFN/RBV therapy on both IR and β-cell function in CHC patients has rarely been investigated.

METHODS

A total of 277 non-diabetic patients treated with PegIFN-α and weight-based RBV, with 80/80/80 adherence, were recruited. Their IR and β-cell function by homeostasis model assessment model (HOMA-IR and HOMA-%B) before treatment and at 24 week after treatment [end of follow-up (EOF)] was measured.

RESULTS

A sustained virological response (SVR) was achieved by 79.4% (220/277) of all patients: 63.6% (75/118) of genotype-1 and 91.2% (145/159) of genotype-non-1 patients. There was no significant change of HOMA-IR post-therapy (2.25 ± 2.46 vs 2.04 ± 2.12, P=0.42). By contrast, there was a significant reduction of HOMA-%B of all patients at EOF (122.9 ± 145.2 vs 92.4 ± 73.2, P=0.001), particularly in those responders (119.1 ± 142.1 vs 89.6 ± 70.3, P=0.002). In 80 patients with high baseline HOMA-IR, both HOMA-IR and HOMA-%B decreased significantly at EOF, irrespective of SVR achievement.

CONCLUSION

This study demonstrated pancreatic β-cell function was ameliorated by PegIFN/RBV therapy in CHC patients, particularly in those responders.

Type 1 diabetes and interferon therapy: a nationwide survey in Japan

OBJECTIVE

Interferon therapy can trigger induction of several autoimmune diseases, including type 1 diabetes. To assess the clinical, immunologic, and genetic characteristics of type 1 diabetes induced by interferon therapy, we conducted a nationwide cross-sectional survey.

RESEARCH DESIGN AND METHODS

Clinical characteristics, anti-islet autoantibodies, and HLA-DR typing were examined in 91 patients for whom type 1 diabetes developed during or shortly after interferon therapy.

RESULTS

Median age at the onset of type 1 diabetes was 56 (interquartile range 48-63) years and mean ± SD BMI was 20.8 ± 2.7 kg/m(2). The time period from the initiation of interferon therapy to type 1 diabetes onset in patients receiving pegylated interferon and ribavirin was significantly shorter than that in patients with nonpegylated interferon single therapy (P < 0.05). Anti-islet autoantibodies were detected in 94.5% of patients at diabetes onset. Type 1 diabetes susceptibility HLA-DRs in the Japanese population, DR4 and DR9, were also associated with interferon treatment-related type 1 diabetes. Furthermore, the prevalence of HLA-DR13 was significantly higher in interferon treatment-related type 1 diabetes than in healthy control subjects (odds ratio 3.80 [95% CI 2.20-7.55]; P < 0.0001) and classical type 1 diabetes (2.15 [1.17-3.93]; P < 0.05).

CONCLUSIONS

Anti-islet autoantibodies should be investigated before and during interferon therapy to identify subjects at high risk of type 1 diabetes. Stronger antiviral treatment may induce earlier development of type 1 diabetes. Furthermore, patients who develop interferon-induced type 1 diabetes are genetically susceptible.

Type 1 Diabetes Mellitus Associated with Pegylated Interferon-α Plus Ribavirin Treatment for Chronic Hepatitis C: Case Report and Literature Review

Combined pegylated interferon (PEG-IFN)+ribavirin (RBV) therapy has been used as a primary treatment for chronic hepatitis C. However, IFN-induced autoimmune disease, including type 1 diabetes mellitus, has been highlighted as one of the problems with this therapy. Here we report the case of a patient who developed type 1 diabetes mellitus during combined PEG-IFN+RBV therapy for hepatitis C but who showed no exacerbation of diabetes despite continued use of IFN. A 63-year-old man with chronic hepatitis C and a nonresponder to previous IFNα treatments, was admitted to our hospital because of excessive thirst, polydipsia, and polyuria 24 weeks after the start of PEG-IFNα+RBV therapy. High levels of blood glucose and glycosylated hemoglobin and low levels of C-peptide and immunoreactive insulin were observed. The serum antiglutamic acid decarboxylase antibody titer was 27,700 U/mL. We diagnosed IFN-induced type 1 diabetes mellitus; however PEG-IFNα+RBV therapy was continued for 48 weeks. Serum HCV remains negative five years after this treatment. Intensive insulin therapy was started immediately after the diagnosis of type 1 diabetes. Although the patient initially required 22 U/day of insulin, the dosage could be gradually reduced after completion of PEG-IFNα+RBV therapy and blood glucose remained well controlled. Prediction of onset of type 1 diabetes mellitus on the basis of baseline measurement of pancreas-associated autoantibodies is difficult. Therefore, it would be advisable to consider the possibility of onset of type 1 diabetes mellitus in all patients receiving IFN+RBV therapy.

Trajectories of anti-islet autoantibodies before development of type 1 diabetes in interferon-treated hepatitis C patients. Case reports and a literature review

Interferon-alpha (IFN-α) is widely used in the treatment of viral hepatitis, however, it is known that IFN-α therapy may induce type 1 diabetes. We report here on two cases of chronic viral hepatitis C who developed autoimmune type 1 diabetes during Peg-IFN-α plus ribavirin (RBV) therapy. Case 1: a 48-year-old male with chronic hepatitis C with chronic thyroiditis. The patient's plasma glucose level was normal and anti-islet autoantibody tests were negative before Peg-IFN-α+RBV therapy. The emergence of glutamic acid decarboxylase 65 autoantibody (GAD65Ab) was observed after five months of treatment. Autoantibodies to insulin and insulinoma-associated antigen-2 (IA-2) also became positive. Eleven months later, thirst and polydipsia occurred with increased fasting plasma glucose level and the patient was diagnosed with type 1A diabetes. Zinc transporter-8 autoantibody (ZnT8Ab) was not detectable at any point. The patient has type 1 diabetes-susceptible HLA-DRB1-DQB1 haplotypes *0405-*0401 and *0901-*0303. Case 2: a 65-year-old male with chronic hepatitis C with type 2 diabetes on insulin treatment. GAD65Ab and IA-2Ab were negative before Peg-IFN-α+RBV therapy, however, nine months later, a single appearance of GAD65Ab was observed. After twelve months, his plasma glucose control worsened rapidly, and he was diagnosed with type 1A diabetes. IA-2Ab and ZnT8Ab were negative throughout the clinical course. His HLA-DRB1-DQB1 haplotypes were *0410-*0402 and *1407-*0503. Both cases showed a unique GAD65Ab epitope (amino acids 360-442). These clinical courses suggest that IFN-α therapy provoked acute islet autoimmunity and onset of type 1 diabetes. Therefore, during IFN-α therapy, patients should be closely monitored for the occurrence of type 1 diabetes.

Dual onset of type 1 diabetes mellitus and Graves' disease during treatment with pegylated interferon alpha-2b and ribavirin for chronic hepatitis C

Currently, a combination therapy of pegylated (PEG) interferon (IFN) alpha-2b and ribavirin are being widely used for the treatment of chronic hepatitis C (CHC). We describe here a case of dual onset of type 1 DM accompanied by ketoacidosis, and Graves' disease during the combination therapy via the autoimmune process.

Association of pancreatic autoantibodies and human leukocyte antigen haplotypes with resolution of diabetes mellitus after therapy for hepatitis C virus infection in patients with HIV infection: case report and review of literature

Diabetes mellitus (DM) is a well known complication of interferon therapy for chronic hepatitis C virus (HCV) infection, but resolution of interferon-induced DM was rarely reported. In HIV and HCV co-infected patients, only two cases of incident DM during interferon therapy were reported and both cases required permanent insulin treatment. We report the first case of HIV/HCV co-infected patient who developed diabetic ketoacidosis during treatment for chronic HCV infection with complete resolution of DM after treatment cessation. Review of reported cases indicates that pancreatic autoantibodies and human leukocyte antigen haplotypes may predict the outcome of interferon-induced diabetes.

Safety of peginterferon in the treatment of chronic hepatitis C

BACKGROUND

Combination of 'pegylated' interferons (IFNs) plus ribavirin, the standard treatment of chronic hepatitis C (CHC), is frequently associated with side effects. Anticipation, recognition and proper management of these side effects are important to ensure compliance with therapy and achievement of sustained virologic response.

OBJECTIVE

To illustrate the side effect profile of pegIFN-alpha in the treatment of CHC.

METHODS

Studies and abstracts were identified through a computerized, English language literature search. Key search terms included peginterferon and CHC. Information available only in abstract form was retrieved from national and international hepatology associations.

RESULTS

Most adverse events occurring with combination therapy can be anticipated and managed appropriately; therefore, premature discontinuation of therapy owing to side effects is not required in most patients.

Peginterferon (PEG-IFN) plus ribavirin combination therapy, but neither interferon nor PGE-IFN alone, induced type 1 diabetes in a patient with chronic hepatitis C

Interferon (IFN) therapies, including IFN, peginterferon (PEG-IFN) and ribavirin (RBV) plus PEG-IFN combination, are widely used for patients with chronic hepatitis C. We encountered a patient with chronic hepatitis C in whom previous IFN or PEG-IFN alone had not induced type 1 diabetes (T1D), while the addition of RBV to PEG-IFN did induce T1D. The patient had HLA types conferring highly susceptibility to T1D. Thus, adding RBV to PEG-IFN may render chronic hepatitis C patients, with T1D-susceptible HLA types, more prone to developing T1D than IFN or PEG-IFN alone. To prevent T1D development, we recommend HLA typing prior to initiating RBV plus PEG-IFN administration.

Abrupt onset of type 1 diabetes mellitus during recombinant interferon-alpha 2b therapy in a patient with chronic hepatitis B

We describe a case of a 33-year-old female patient with chronic hepatitis B who developed type 1 diabetes mellitus (DM) after a 13-mo period of treatment with recombinant human interferon-alpha (IFN-α) 2b. The patient presented with polydipsia, polyuria, hyperglycemia, diabetic ketoacidosis, combined with C-peptide secretion deficiency and positive islet cell autoantibody (ICAb). IFN-α 2b treatment was terminated and instead insulin treatment was initiated. Five months after cessation of the recombinant human IFN-α 2b therapy, the patient remained insulin-dependent. Her serum HBV DNA became negative and serum transaminase returned to the normal level after a 10-mo period of IFN therapy. Type 1 DM induced by IFN-α is relatively rare in patients with chronic hepatitis B. We should pay more attention to patients on IFN-α therapy to avoid destruction of pancreatic beta cells. This is the first case report from China.

Sudden onset of diabetic ketoacidosis during consensus interferon therapy for chronic viral hepatitis C

INTRODUCTION

Interferon (IFN)-alpha, used for the treatment of chronic hepatitis C, has rarely been associated with the development of diabetes. Consensus interferon (CIFN), which is used for nonresponders, has not been associated with this complication. We describe the first case of new onset diabetes in a patient on CIFN.

CASE

A 50-year-old man with chronic hepatitis C and no prior diabetes was started on IFN-alpha. After 24 weeks with a detectable viral load, he was switched to CIFN. Four weeks later, he presented in diabetic ketoacidosis which resolved with appropriate therapy without any ascertainable etiology (glutamic acid decarboxylase negative). Within 9 months he was off insulin, and is off all diabetic medications with an HgA1c of 5.6% 2 years after the episode.

Type 1 diabetes mellitus provoked by peginterferon alpha-2b plus ribavirin treatment for chronic hepatitis C

A 51-year-old man developed type 1 diabetes mellitus following 24 weeks of treatment with recombinant alpha-2b peginterferon plus ribavirin for chronic hepatitis C. Pancreatic autoantibody tests were negative before the start of therapy, but a significant increase in glutamic acid decarboxylase (GAD) antibody titer was seen after 24 weeks of treatment. Six months after the onset of type 1 diabetes mellitus, the patient continues to receive 40 units of insulin daily. The clinical course suggested that recombinant alpha-2b peginterferon plus ribavirin provoked type 1 diabetes mellitus, therefore, in patients who are candidates for interferon therapy the presence of pancreatic autoantibodies and the fasting plasma glucose level should be investigated before and during treatment.

High incidence of type 1 diabetes mellitus during or shortly after treatment with pegylated interferon alpha for chronic hepatitis C virus infection

BACKGROUND

Development of diabetes mellitus (DM) during or shortly after treatment with interferon alpha (IFN-alpha) in patients with chronic hepatitis C virus (HCV) infection has been reported sporadically. We prospectively screened for DM during and after IFN-alpha therapy for chronic HCV infection.

METHODS

Blood glucose levels of patients with chronic HCV infection were routinely assessed at all outpatient visits during and after treatment with pegylated-IFN-alpha (Peg-IFN-alpha) and ribavirin (Riba).

RESULTS

Between December 2002 and October 2005, 189 non-diabetic patients were treated with Peg-IFN-alpha/Riba, of whom five developed type 1 DM (2.6%), three type 2 DM (1.6%) and one an indeterminate type of DM. Classical symptoms of DM were present in three patients who developed DM shortly after cessation of Peg-IFN-alpha/Riba. In the other patients, symptoms of DM were either indistinguishable from side effects caused by Peg-IFN-alpha/Riba or absent.

CONCLUSION

Our study showed a high incidence of type 1 DM during Peg-IFN-alpha/Riba therapy for chronic HCV infection. Symptoms of DM may be absent or mistaken for Peg-IFN-alpha/Riba-associated side effects. To diagnose DM without delay, we propose routine assessment of blood glucose at all outpatient visits during and after Peg-IFN-alpha/Riba treatment in chronic HCV patients.

Syndromes and complications of interferon therapy

PURPOSE OF REVIEW

Interferons are used to treat a variety of medical conditions. They are integral players in immunity and a number of immune-mediated complications can arise during interferon therapy. We have reviewed the occurrence of these complications, and the mechanisms behind them.

RECENT FINDINGS

Case reports and follow-up studies of large cohorts of patients on interferon therapy have confirmed that immune-mediated complications are uncommon but can occur in a number of different organ systems. IFNalpha production is induced by specific autoantibody-nuclear antigen immune complexes, and has a key role in the development and maintenance of autoimmunity in systemic lupus erythematosus.

SUMMARY

Interferon therapy can precipitate immune-mediated abnormalities de novo or can exacerbate an existing autoimmune tendency. This is manifest in the rise in titre of existing antibodies and in the development of clinical disease in patients with preexisting antibodies. Type I interferons have a key role in the development of systemic lupus erythematosus.

Simultaneous development of diabetic ketoacidosis and Hashitoxicosis in a patient treated with pegylated interferon-alpha for chronic hepatitis C

Classical interferon-alpha has been shown to be correlated with the development of a variety of autoimmune disorders. A 38 year-old female patient developed simultaneously diabetic ketoacidosis and hyperthyroidism 5 mo following initiation of treatment with pegylated interferon-α and ribavirin for chronic hepatitis C. High titers of glutamic acid decarboxylase, antinuclear and thyroid (thyroid peroxidase and thyroglobulin) antibodies were detected. Antiviral treatment was withdrawn and the patient was treated with insulin for insulin-dependent diabetes mellitus and propranolol for hyperthyroidism. Twelve months after cessation of pegylated interferon-α therapy the patient was euthyroid without any medication but remained insulin-dependent.
