Four cases of type 1 diabetes mellitus showing sharp serum transaminase increases and hepatomegaly due to glycogenic hepatopathy

Glycogenic hepatopathy is associated with type 1 diabetes mellitus in only a minority of cases in a contemporary adult population

OBJECTIVES

This study examines the clinical-pathological profiles of patients with glycogenic hepatopathy in a contemporary cohort of patients at an adult acute care hospital.

METHODS

Liver biopsies with glycogenic hepatopathy were retrieved from the departmental surgical pathology database, the histological findings were studied, and the clinical findings were reviewed.

RESULTS

Five cases of glycogenic hepatopathy were found, including cases associated with type 1 diabetes mellitus (n = 1), type 2 diabetes mellitus (n = 1), corticosteroids (n = 2), and anorexia (n = 2, including the patient with type 1 diabetes). AST and ALT were normal to mildly elevated (13-115 U/L and 7-126 U/L, respectively). Trace ascites was present in two patients. Hepatomegaly was only present in the patient with type 1 diabetes at the time of diagnosis.

CONCLUSIONS

Four of five cases were associated with etiologies other than type 1 diabetes, which is widely reported as the most common etiology of glycogenic hepatopathy. This study suggests that etiologies currently only rarely recognized may actually be more common causes of glycogenic hepatopathy than type 1 diabetes in a contemporary adult population. It is important not only to recognize that these rarely reported causes of glycogenic hepatopathy may be underrecognized, but that the clinical presentation may also be mild.

Hepatopathy Associated With Type 1 Diabetes: Distinguishing Non-alcoholic Fatty Liver Disease From Glycogenic Hepatopathy

Autoimmune destruction of pancreatic β-cells results in the permanent loss of insulin production in type 1 diabetes (T1D). The daily necessity to inject exogenous insulin to treat hyperglycemia leads to a relative portal vein insulin deficiency and potentiates hypoglycemia which can induce weight gain, while daily fluctuations of blood sugar levels affect the hepatic glycogen storage and overall metabolic control. These, among others, fundamental characteristics of T1D are associated with the development of two distinct, but in part clinically similar hepatopathies, namely non-alcoholic fatty liver disease (NAFLD) and glycogen hepatopathy (GlyH). Recent studies suggest that NAFLD may be increasingly common in T1D because more people with T1D present with overweight and/or obesity, linked to the metabolic syndrome. GlyH is a rare but underdiagnosed complication hallmarked by extremely brittle metabolic control in, often young, individuals with T1D. Both hepatopathies share clinical similarities, troubling both diagnosis and differentiation. Since NAFLD is increasingly associated with cardiovascular and chronic kidney disease, whereas GlyH is considered self-limiting, awareness and differentiation between both condition is important in clinical care. The exact pathogenesis of both hepatopathies remains obscure, hence licensed pharmaceutical therapy is lacking and general awareness amongst physicians is low. This article aims to review the factors potentially contributing to fatty liver disease or glycogen storage disruption in T1D. It ends with a proposal for clinicians to approach patients with T1D and potential hepatopathy.

Acute Hepatitis due to Hepatic Glycogenosis After Insulin Overdose and Oral Glucose Administration in an Adolescent

Background

Hepatic glycogenosis (HG) has been reported after intravenous (IV) dextrose administration to treat insulin overdose. We describe a case of HG in a patient with type 1 diabetes mellitus (T1DM) due to insulin overdose treated with oral glucose administration.

Case Presentation

An adolescent boy with T1DM on a basal bolus insulin regimen presented with abdominal discomfort, nausea, vomiting, and hypoglycemia of a few hours. His glucose was 71 mg/dL, aspartate transaminase (AST) 119 U/L, and alanine transaminase (ALT) 65 U/L. Hypoglycemia was treated with juice, and 12 hours later AST and ALT were 979 U/L and 700 U/L, respectively. Workup for infectious, autoimmune, metabolic, and toxic causes of hepatitis was negative. The transaminases improved by the next day and normalized within 3 weeks. Two weeks after discharge the patient returned with hypoglycemia, nausea, and right-sided abdominal pain of 13 hours. Hypoglycemia persisted despite multiple courses of glucose tablets and juice. Laboratory studies showed glucose of 58 mg/dL, AST of 776 U/L, ALT of 496 U/L, negative toxicology studies, and normal abdominal ultrasound. His serum insulin level was 249.7 mU/L and, C-peptide was less than 0.1 ng/mL, consistent with insulin overdose. He received IV fluids with dextrose, and insulin was held. Transaminases improved by the following day. Repeat serum insulin while on home regimen was normal.

Conclusion

Along with other diagnoses, HG should be considered in patients treated with insulin who present with hypoglycemia and acute hepatitis. HG can occur in cases of insulin overdose treated with repeated oral glucose administration.

Persistent lactic acidosis in the Mauriac syndrome in type 1 diabetes mellitus

Mauriac syndrome is an uncommon clinical condition arising in the setting of poorly controlled type 1 diabetes mellitus. Clinical features include hepatomegaly and liver abnormalities indistinguishable from nonalcoholic fatty liver disease. Early diagnosis and management are essential, as Mauriac syndrome is reversible.

Liver disease in children and adolescents with type 1 diabetes mellitus: A link between glycemic control and hepatopathy

AIM

The aim of this study was to assess the prevalence of liver disease in children and adolescents with type-1 diabetes mellitus (T1DM) by detection of elevated liver transaminases, confirmed by fibroscan and ultrasound. The secondary objective was to assess the effect of glycemic control on improvement of liver functions.

METHODS

One hundred and seven children and adolescents with T1DM were investigated by liver transaminases, mean HbA1c and pelviabdominal ultrasound while fibroscan was done for those with elevated liver transaminases only. Patients with elevated liver enzymes were reassessed after one year.

RESULTS

Only nine (8.4%) of the studied patients have exhibited liver dysfunction in the form of elevated liver transaminases with median ALT 140 U/L and AST 191 U/L and hepatomegaly by ultrasound; The HbA1c (median = 10.8%) and fibroscan abnormalities (median fibrosis score 1) were significantly higher in patients with elevated liver transaminases (p < 0.001). Adequate glycemic control resulted in a significant decrease in liver transaminases (median ALT = 25 U/L and AST = 29 U/L), fibroscan fibrosis score (median = 0) and HbA1c (median = 9%) (p = 0.003), (p = 0.01) and (p = 0.003) respectively.

CONCLUSION

Adequate glycemic control was associated with improvement of liver disease in children and adolescents with diabetes.

Evaluation of biomarkers in liver following Solanum melongena green calyx administration in diabetic rats

Background

Solanum melongena green calyx (SMGC) has antioxidant properties. Diabetes mellitus (DM) increases oxidative stress and causes cellular damages in liver. This study attempts to show the protective effects of SMGC against morphometric, inflammatory, oxidative, and apoptotic changes in liver following DM induction.

Methods

For DM induction, the streptozotocin (60 mg/kg) was injected intraperitoneally. After the preparation of the SMGC extract, phytochemical content was analyzed. Sixty-four rats were categorized into 8 groups (n = 8); control, diabetic, SMGC, and diabetic + SMGC. SMGC administration was applied orally with doses of 100, 300, 500 mg/kg for 4 weeks. The assays of nitrite oxide, lipid peroxidation (LP), and Ferric Reducing Ability of Plasma (FRAP) were conducted for sample analysis. P53, Bcl2, and Bax genes expression, inflammatory cytokines, enzymes, and morphological features were measured. Apoptotic cell index, body weight, and levels of glucose and insulin were also analyzed. A one-way ANOVA test was used for statistical analysis.

Result

According to the phytochemical analysis, the SMGC is rich in Tannins and Saponins. Antioxidant values, p53 and Bax genes expression, inflammatory cytokines, enzymes, body weight, serum glucose, and morphometrical features were increased significantly (except insulin and FRAP levels and Bcl2 gene expression which were decreased) in diabetic group compared to the control group (P < 0.05). Also, evaluated parameters were reduced significantly (except insulin and FRAP levels and Bcl2 gene expression which were increased) in SMGC and diabetic + SMGC groups in comparison with the diabetic group (P < 0.05).

Conclusion

These findings revealed that the SMGC attenuates blood glucose levels in diabetic animals and also eliminates destructive effects of DM on liver through antioxidant features.

Diabetes Association with Liver Diseases: An Overview for Clinicians

BACKGROUND

There is a strong association between liver diseases and diabetes (DM) which is higher than expected by a correlation between two very common diseases. Liver diseases may occur as a result of diabetes, and the reverse is true as well.

AIM

To review the etiology of this association between liver diseases and diabetes and how to diagnose it.

METHODS

Studies that identified this association between liver diseases and diabetes and how to diagnose it was reviewed.

RESULTS

This association can be divided into the following categories: liver disease related to diabetes (Diabetic hepatopathy), hepatogenous diabetes (HD), and liver diseases that occur in conjunction with Diabetes mellitus. Two hours after glucose loading is the best screening test for HD. HbA1c may neither be suitable for diagnosis nor monitoring of diabetes that links liver disease.

CONCLUSION

NAFLD, hepatogenous diabetes, glycogenic hepatopathy and diabetic hepatosclerosis are the most important association between liver diseases and diabetes. The criteria for the diagnosis of diabetes associating liver disease are the same for primary diabetes. Two hours post glucose load is the best screening test for HD due to the fact that fasting glucose can be normal early in the disease. The tool used for diabetes monitoring depends on stage and severity of liver condition.

Glycogenic hepatopathy as an unusual etiology of deranged liver function in a patient with type 1 diabetes: A case report

RATIONALE

Deranged liver function is a common finding among patients with diabetes mellitus. We report a case of liver biopsy-proven glycogenic hepatopathy (GH) in a patient with long-standing poorly controlled type 1 diabetes (DM1), presented with recurrent transaminitis.

PATIENT CONCERNS

A 28-year-old Chinese woman was noted to have deranged liver function with transaminases elevated to more than 15 times the upper limit of normal.

DIAGNOSIS

She had underlying long-standing poorly controlled DM1. Blood tests including hepatitis serology and autoimmune panel were negative. Liver biopsy confirmed the diagnosis of GH, showing an increase in glycogen deposition with intact liver parenchymal architecture, and no inflammation or significant fibrosis.

INTERVENTIONS

Her glycemic control was optimized.

OUTCOMES

Her transaminase levels normalized upon subsequent follow-up with improved glycemic control.

LESSONS

GH is suspected when transaminase flare occurs in patients with poorly controlled DM1, usually with exaggerated hemoglobin A1c levels, especially after drug-induced, viral, autoimmune and metabolic liver diseases are excluded. The gold standard of diagnosis is liver biopsy. When diagnosis of GH is ascertained, the mainstay of treatment is to optimize glycemic control. Typically, the transaminases may become normal within days to months after improvement of glycemic control. Compared to non-alcoholic fatty liver disease, GH is associated with favorable prognosis and runs a benign course, making this differentiation clinically important.

Glycogenic hepatopathy as a cause of severe deranged liver enzymes in a young patient with type 1 diabetes mellitus

Glycogenic hepatopathy (GH) is a rare complication of poorly controlled type 1 diabetes mellitus (T1DM). We present a 19-year-old woman with T1DM and autoimmune thyroiditis who admitted to our department because of abrupt onset intermittent abdominal pain in the right upper quadrant accompanied by laboratory evidence of acute anicteric hepatitis. Physical examination revealed significant hepatomegaly but the common imagining studies were negative. Following exclusion of common causes of acute hepatitis and because of the presence of smooth muscle antibodies in a young female patient with already established two autoimmune diseases, a liver biopsy was performed in order to exclude the potential presence of autoimmune hepatitis. However, liver histology showed typical findings of GH. Intense treatment targeting strict glycemic control resulted in normalisation of liver biochemistry. This case underlines that GH should be considered as a rare cause of acute hepatitis in T1DM patients with poor glycemic control.

An Unusual Presentation of Glycogenic Hepatopathy with Bridging Fibrosis

Glycogenic hepatopathy is a rare and under-recognized complication of poorly controlled diabetes mellitus. We report a patient who presented with predominant elevation in alkaline phosphatase and liver biopsy showing bridging fibrosis, which is an unusual presentation of glycogenic hepatopathy. This case emphasizes the fact that glycogenic hepatopathy can also present with a cholestatic pattern of liver abnormality and with liver fibrosis, which warrants further study because severe fibrosis can progress to cirrhosis.

Glycogenic Hepatopathy in Type 1 Diabetes Mellitus

Glycogenic hepatopathy (GH) is a rare complication of poorly controlled type 1 diabetes mellitus (T1DM), and is characterized by elevated liver enzymes, hepatomegaly, and glycogen accumulation. We herein present the case of a 23-year-old man with poorly controlled T1DM who had liver dysfunction. Imaging studies showed severe hepatomegaly and fatty liver. The examination of a liver biopsy specimen revealed fatty droplets, ballooning, inflammation, and mild fibrosis. Subsequent periodic acid-Schiff (PAS) staining after diastase digestion confirmed GH. In this case, the improvement of hyperglycemia, not HbA1c, resulted in the improvement of the patient's liver function. This is the first report on the use of continuous glucose monitoring in patients with GH to show that continuous hyperglycemia may worsen GH.

Glycogenic hepatopathy: A narrative review

Glycogenic hepatopathy (GH) is a rare complication of the poorly controlled diabetes mellitus characterized by the transient liver dysfunction with elevated liver enzymes and associated hepatomegaly caused by the reversible accumulation of excess glycogen in the hepatocytes. It is predominantly seen in patients with longstanding type 1 diabetes mellitus and rarely reported in association with type 2 diabetes mellitus. Although it was first observed in the pediatric population, since then, it has been reported in adolescents and adults with or without ketoacidosis. The association of GH with hyperglycemia in diabetes has not been well established. One of the essential elements in the pathophysiology of development of GH is the wide fluctuation in both glucose and insulin levels. GH and non-alcoholic fatty liver disease (NAFLD) are clinically indistinguishable, and latter is more prevalent in diabetic patients and can progress to advanced liver disease and cirrhosis. Gradient dual-echo MRI can distinguish GH from NAFLD; however, GH can reliably be diagnosed only by liver biopsy. Adequate glycemic control can result in complete remission of clinical, laboratory and histological abnormalities. There has been a recent report of varying degree of liver fibrosis identified in patients with GH. Future studies are required to understand the biochemical defects underlying GH, noninvasive, rapid diagnostic tests for GH, and to assess the consequence of the fibrosis identified as severe fibrosis may progress to cirrhosis. Awareness of this entity in the medical community including specialists is low. Here we briefly reviewed the English literature on pathogenesis involved, recent progress in the evaluation, differential diagnosis, and management.

Focal Hepatic Glycogenosis in a Patient With Uncontrolled Diabetes Mellitus Type 1

Hepatomegaly and elevated liver enzymes in patients with diabetes are commonly associated with fatty liver disease. However, physicians often forget about another intrinsic substance that can cause a similar clinical picture-glycogen. Liver stores approximately one third of the total body glycogen and is responsible for blood glucose homeostasis. Excessive hepatocellular glycogen accumulation occurs not only in congenital glycogen storage diseases, but also in acquired conditions associated with hyperglycemic-hyperinsulinemic states such as uncontrolled diabetes mellitus, high-dose corticosteroid use, and dumping syndrome. All reported cases of acquired abnormal glycogen deposition described a diffuse form of hepatic glycogenosis with the entire liver involved in the accumulating process. To our knowledge, this is the first reported case of abnormal focal glycogen deposition in a patient with diabetes mellitus type 1 with imaging and pathologic correlation. Awareness of the imaging appearance of focal glycogen deposition can help to distinguish it from other pathologic conditions.

Glycogenic hepatopathy, an underdiagnosed cause of relapsing hepatitis in uncontrolled type 1 diabetes mellitus

Glycogenic hepatopathy is a rare condition that causes significant hepatomegaly and elevated liver enzyme levels in uncontrolled type 1 diabetic patients. It develops due to excessive accumulation of glycogen in the hepatocytes. It is typically reversible with good glycemic control and rarely progresses to mild fibrosis, but not cirrhosis.
