It is well established that acute pancreatitis (AP) often causes diabetes mellitus. However, whether pre-existing diabetes is associated with the development of AP remains unknown. To clarify the association of pre-existing diabetes and the development of AP, we carried out a meta-analysis of observational studies. A computerized literature search was performed in MEDLINE (from 1 January 1966) and EMBASE (from 1 January 1974), through 31 January 2012. We also searched the reference lists of relevant articles. Summary relative risks with their corresponding 95% confidence intervals (CIs) were calculated using a random-effects model. Between-study heterogeneity was assessed using Cochran's Q statistic and the I 2. A total of seven articles (10 523 incident cases of AP) were included in this meta-analysis. Analysis of seven studies indicated that, compared with nondiabetic individuals, diabetic individuals had a 92% increased risk of development of AP (95% CI 1.50-2.47). There was significant evidence of heterogeneity among these studies (P heterogeneity<0.001, I 2=93.0%). These increased risks were independent of alcohol use, gallstones, and hyperlipidemia. Although the current evidence supports a positive link between pre-existing diabetes and an increased risk of development of AP, additional studies, with a perfect design, are required before definitive conclusions can be drawn.
    • "Furthermore , GA is reported to serve as a better indicator of glycemic control than HbA1c in diabetic patients on dialysis212223. Findings from the DCCT/EDIC and other studies2425262728 revealed the association of increased GA values with the presence of diabetic retinopathy, nephropathy, and cardiovascular complications; these findings also support the use of GA measurements in the diagnosis of diabetes. The present study was undertaken to ascertain whether measurement of GA can be employed to determine the need for an OGTT in the diagnosis of diabetes. "
    [Show abstract] [Hide abstract] ABSTRACT: In the diagnosis of diabetes mellitus, hemoglobin A1c (HbA1c) is sometimes measured to determine the need of an oral glucose tolerance test (OGTT). However, HbA1c does not accurately reflect glycemic status in certain conditions. This study was performed to test the possibility that measurement of serum glycated albumin (GA) better assesses the need for OGTT. From 2006 to 2012, 1559 subjects not known to have diabetes or to use anti-diabetic medications were enrolled. Serum GA was measured, and a 75-g OGTT was then performed to diagnose diabetes. Serum GA correlated significantly to age (r = 0.27, p<0.001), serum albumin (r = -0.1179, age-adjusted p = 0.001), body mass index (r = -0.24, age-adjusted p<0.001), waist circumference (r = -0.16, age-adjusted p<0.001), and plasma GA (r = 0.999, p<0.001), but was unaffected by diet (p = 0.8). Using serum GA at 15% for diagnosis of diabetes, the sensitivity, specificity, and area under the receiver-operating characteristic curve were 74%, 85%, and 0.86, respectively. Applying a fasting plasma glucose (FPG) value of < 100 mg/dL to exclude diabetes and of ≥ 126 mg/dL to diagnose diabetes, 14.4% of the study population require an OGTT (OGTT%) with a sensitivity of 78.8% and a specificity of 100%. When serum GA value of 14% and 17% were used to exclude and diagnose diabetes, respectively, the sensitivity improved to 83.3%, with a slightly decrease in specificity (98.2%), but a significant increase in OGTT% (35%). Using combined FPG and serum GA cutoff values (FPG < 100 mg/dL plus serum GA < 15% to exclude diabetes and FPG ≥ 126 mg/dL or serum GA ≥ 17% to diagnose diabetes), the OGTT% was reduced to 22.5% and the sensitivity increased to 85.6% with no change in specificity (98.2%). In the diagnosis of diabetes, serum GA measurements can be used to determine the need of an OGTT.

    • "Improvement occurred with remission of systemic inflammatory response syndrome and weight loss. There is a bidirectional relationship between dysglycaemia and pancreatitis [4, 6, 7]. Acute pancreatitis could induce beta cell dysfunction and transient insulin deficiency and also could increase insulin resistance due to systemic inflammation. "
    [Show abstract] [Hide abstract] ABSTRACT: A 30-year-old obese male patient had been diagnosed with diabetes mellitus due to acute hyperglycemia and ketonuria. He also presented with severe hypertriglyceridemia and high levels of serum lipase. He was initially misdiagnosed with type 1 diabetes and treated with insulin for one month. At two months from first presentation, pancreatic antibodies were negative, and the C-peptide level was normal. A1c level was 5.9% without insulin treatment. The association between diabetes mellitus and acute pancreatitis is well established. We reported a case of severe transient hyperglycemia during mild acute pancreatitis in a metabolically ill patient.

  • [Show abstract] [Hide abstract] ABSTRACT: To describe clinical and epidemiological characteristics of patients with very high hypertriglyceridemia (HTG) who were attended in lipid units of the Spanish Society of Atherosclerosis (SEA). Patients of the HTG Registry of SEA with at least one triglyceride concentration greater than 1,000mg/dL (n=298, HTG severe group) and those whose baseline triglycerides were between 200 and 246mg/dL (HTG control group, n=272) were included. Patients with very high triglyceride levels were younger (46.9±11.5 years vs 52.7±13 years; p<0.0001), with a larger waist circumference (100.5±10.6cm vs 98.5±11.1cm; p=0.0426), higher alcohol intake (170.7±179.1g/wk vs 118.8±106.4g/wk; p=0,0473), active smoking status (45.6% vs 26.8%; p<0.0001) and a higher frequency of pancreatitis (10.2% vs 3%; p=0.0006) than HTG control group. There was a higher percentage of patients with atherogenic dietary pattern in severe HTG group compared with the control group (138 [46.3%] vs. 94 [34.5%]; p=0,001). The multivariate analysis showed that factors associated with a triglyceride concentration greater than 1,000mg/dl were age, male sex, weight, waist circumference, alcohol, physical inactivity in non-business hours and the presence of diabetes mellitus. Patients with very high HTG were usually men in the fourth decade of life, with abdominal obesity, smoking and alcohol consumption. In 60% of cases the HTG was primary, and pancreatitis the most frequently complication.
