Abstract
BACKGROUND To compare glycemic variability (GV) indices between patients with fibrocalculous pancreatic diabetes (FCPD) and type 2 diabetes mellitus (T2D) using continuous glucose monitoring (CGM). METHODS We measured GV indices using CGM (iPro™2 Professional CGM, Medtronic, USA) data in 61 patients each with FCPD and T2D who were matched for glycated hemoglobin A1c (HbA1c) and duration of diabetes. GlyCulator2 software was used to estimate the CGM-derived measures of GV (SD, mean amplitude of glycemic excursion [MAGE], continuous overall net glycemic action [CONGA], absolute means of daily differences [MODD], M value, and coefficient of variance [%CV]), hypoglycemia (time spent below 70 mg/dL, AUC below 70 mg/dL, glycemic risk assessment diabetes equation hypoglycemia, Low Blood Glucose Index), and hyperglycemia (time spent above 180 mg/dL at night [TSA > 180], AUC above 180 mg/dL [AUC > 180], glycemic risk assessment diabetes equation hyperglycemia, High Blood Glucose Index [HBGI], and J index). The correlation of GV indices with HbA1c, duration of diabetes, and demographic and biochemical parameters were also assessed. RESULTS All the CGM-derived measures of GV (SD, MAGE, CONGA, MODD, and %CV), except M value, were significantly higher in the FCPD group than in the T2D group (P < 0.05). Measures of hyperglycemia (TSA >180, AUC >180, HBGI, and J index) were significantly higher in the FCPD group than in the T2D group (P < 0.05). The measures of hypoglycemia were not significantly different between the two groups. All the hyperglycemia indices showed a positive correlation with HbA1c in both groups. CONCLUSIONS FCPD is associated with higher GV than is T2D. The findings of higher postprandial glycemic excursions in patients with FCPD could have potential therapeutic implications.

Abstract
We report a 30-year-old woman who was confined to a wheelchair because of severe myopathy. She was first seen by a neurologist because of a convulsive syndrome of unknown etiology when she was nine. She was started on anticonvulsive drugs but the drug was stopped when her serum calcium level was found to be very low. She had a history from childhood of steatorrhea and abdominal pain after a fatty meal and became vegetarian at age five years. She worked in a hospital as a nurse and at home her living room received no direct sunlight. As a result of these conditions osteomalacia progressed. We believe an awareness of chronic pancreatitis (CP) during childhood could have prevented the consequences of the disease in this case.

Abstract
Chronic pancreatitis (CP) is a disabling condition worldwide that presents as pain, maldigestion, and diabetes. It is usually perceived as alcohol related, or classified as idiopathic otherwise. However, this is true only for Western countries. Asian CP comprises not only alcohol-related CP but also tropical pancreatitis (TP). Tropical pancreatitis is a unique entity commonly found in South Asia. It shares similar presentations with other CPs for pain and maldigestion. However, its diabetes is more ketosis resistant. Non-surgical approach like endoscopic therapy plus extracoporeal shock wave lithotripsy provides better outcome for TP than other CPs, because of its less strictured pancreatic duct that is more amenable to endoscopic stone clearance. Diagnosis of CP in Asia mainly relies on image studies such as ultrasonography ± computed tomography (CT) scan, and non-invasive tests on fecal chymotrypsin, serum trypsin, and serum pancreatic isoamylase. Endoscopic ultrasonography and intestinal tubing tests are used mainly in some research centers. Autoimmune pancreatitis (AIP) is another CP originated from Asia in large series and subsequently being recognized in the West. AIP patients seldom present with maldigestion until the disease progresses to a very late stage and this occurs in less than one third of patients. In contrast, AIP is usually presented as pseudotumor of the pancreatic head, causing obstructive jaundice. Immunoglobulin G4 level is typically elevated in AIP and can be used as a marker for responsiveness. Without a need of surgery, steroids are the standard treatment. Those who relapse and are resistant to steroids should be placed on long-term immunosuppressive agents.

Abstract
OBJECTIVE The Cohen diabetes-sensitive rat develops postprandial hyperglycemia when fed a high-sucrose, copper-poor diet, whereas the Cohen diabetes-resistant rat maintains normoglycemia. The pathophysiological basis of diabetes was studied in the Cohen diabetic rat centering on the interplay between the exocrine and endocrine compartments of the pancreas. RESEARCH DESIGN AND METHODS Studies used male Cohen diabetes-sensitive and Cohen diabetes-resistant rats fed 1-month high-sucrose, copper-poor diet. Serum insulin and glucose levels were measured during glucose and insulin tolerance tests. The pancreas was evaluated for weight, insulin content, macrophage, and fat infiltration. Glucose-stimulated insulin secretion (GSIS) was determined in isolated perfused pancreas and in islets. RESULTS Hyperglycemic Cohen diabetes-sensitive rats exhibited reduced pancreatic weight with lipid deposits and interleukin-1beta-positive macrophage infiltration in the exocrine pancreas. Islet morphology was preserved, and total pancreatic insulin content did not differ from that of Cohen diabetes-resistant rats. Lipids did not accumulate in skeletal muscle, nor was insulin resistance observed in hyperglycemic Cohen diabetes-sensitive rats. Intravenous glucose-tolerance test revealed markedly elevated glucose levels associated with diminished insulin output. Insulin release was induced in vivo by the non-nutrient secretagogues arginine and tolbutamide, suggesting a selective unresponsiveness to glucose. Decreased GSIS was observed in the isolated perfused pancreas of the hyperglycemic Cohen diabetes-sensitive rat, whereas islets isolated from these rats exhibited glucose-dependent insulin secretion and proinsulin biosynthesis. CONCLUSIONS The association of the in vivo insulin secretory defect with lipid accumulation and activated macrophage infiltration in the exocrine pancreas suggests that changes in the islet microenvironment are the culprit in the insulin secretory malfunction observed in vivo.

Abstract
BACKGROUND AND AIMS A survey was conducted of chronic pancreatitis (CP) in different countries in the Asia-Pacific region. The main objective of the survey was to generate a database containing information regarding the prevalence, etiology, clinical presentation, diagnostic work-up, and management of CP in the Asia-Pacific region. METHODS Data were collected from seven countries using a structured questionnaire. Expert participants were asked to respond to the questionnaire based on the data of patients with CP studied in their centers. RESULTS The prevalence of CP was found to be very high in southern India (114-200/100 000 population), in contrast to the low reported rate of 4.2/100 000 population in Japan. Alcohol was the most common etiological factor in Australia (95%) and Japan (54%) while idiopathic pancreatitis was the most common type in India (tropical pancreatitis) and China, accounting for approximately 70% of all cases of CP. Pain was the most common clinical feature. Diabetes and steatorrhea were uncommon. With regard to the diagnosis of CP, all the experts believed that a patient could be diagnosed as having CP in the presence of any one or more of the following: ductal changes on endoscopic retrograde cholangiopancreatography, a positive secretin test, pancreatic calcification, and endosonographic abnormalities suggestive of CP. Most experts suggested pancreatic enzymes and analgesics as initial medical therapy for pain relief in CP. Endotherapy was suggested as the therapy of choice if medical therapy failed. Surgery was offered only after the failure of endotherapy. Most experts agreed that research should focus on genetic abnormalities in CP and the role of endotherapy for pain relief. CONCLUSION The survey brought out the prevalent types and presentation of CP, common management practices, and also the shortcomings in the existing knowledge of CP in the Asia-Pacific region. These findings might help focus attention on the research priorities for CP in this region.

Abstract
AIMS In chronic calcific pancreatitis of the tropics, etiology and relationship to developing diabetes mellitus are unknown. Some consider these cases a straightforward secondary type of diabetes, while others suggest selective beta-cell impairment. Testing pancreatic function, we investigated whether selective beta-cell impairment triggers diabetes associated with tropical pancreatitis. METHODS At a Bangladeshi research institute, 8 chronic tropical pancreatitis and no diabetes mellitus subjects, 14 fibrocalculous pancreatic diabetics and 27 matched healthy controls underwent arginine (endocrine pancreatic function) and secretin (exocrine pancreatic function assessment) stimulation tests. RESULTS All patients with clinically-diagnosed, chronic pancreatitis demonstrated pronounced exocrine pancreatic dysfunction with beta-cell functioning differing significantly between the two groups. Compared to controls, patients having tropical pancreatitis and no diabetes showed normal plasma C-peptide values at baseline and after arginine stimulation, while fibrocalculous pancreatic diabetics demonstrated a typical diabetic pattern for plasma C-peptide levels. In contrast, pancreatic alpha-cell functioning (glucagon response to arginine) was preserved in both pancreatitis groups. CONCLUSION A preserved pancreatic alpha-cell function in diabetics with advanced chronic pancreatitis of the tropics supports the concept of two different pathogenic mechanisms, one eliciting chronic pancreatitis and the other selective pancreatic beta-cell impairment and subsequent diabetes mellitus.

Abstract
Tropical pancreatitis is a special type of chronic pancreatitis that is seen mainly in tropical countries. The prevalence of tropical pancreatitis is about 126/100,000 population in southern India. It occurs usually in young people, involves the main pancreatic duct and results in large ductal calculi. The etiology is not known, but genetic mutations such as the SPINK1 gene mutation and environmental factors are likely causes. Clinically, >90% of patients present with abdominal pain. About 25% of patients develop diabetes which generally requires insulin for its control but is ketosis-resistant. Painless diabetes is another clinical presentation in some patients. Most patients develop malnutrition during the course of the disease. Steatorrhea is less common. Patients with tropical pancreatitis may develop pancreatic cancer as a long-term complication. The diagnosis can be established by plain radiography of the abdomen, ultrasonography, computerized tomography scan of the abdomen or endoscopic retrograde cholangiopancreatography. Management is directed towards relief from pain and control of diabetes and steatorrhea. Pain relief can be obtained by analgesics and enzyme supplementation with preparations rich in proteases. Endotherapy coupled with stone fragmentation by extracorporeal shock wave lithotripsy is an effective therapy for those who fail to respond to medical therapy. Surgical decompression of the main pancreatic duct by lateral pancreato-jejunostomy is reserved for patients with severe pain non-responsive to other forms of therapy.

Abstract
The majority of young diabetics in India prefer to use low-cost bovine insulin for economic reasons. Therefore, the question of insulin antibody response to bovine insulin and its functional significance is still relevant in the Indian context. We assessed insulin antibody response in 52 young diabetics (type 1, n=25, malnutrition modulated form of diabetes, n=19 and fibrocalculous pancreatopathy (FCP) n=8) on bovine insulin therapy (mean duration 3.0+/-2.1 years) using an internationally standardised in-house radioligand assay. The functional significance of insulin antibody was assessed by calculating their affinity constant, maximum binding capacity and total insulin binding power by Scatchard analysis (type 1, n=14, malnutrition modulated form of diabetes, n=11). All the patients treated with bovine insulin showed high titers of insulin antibodies with S.D. score ranging from 5.1 to 42.0. No significant difference was observed in the mean S.D. score of insulin antibodies in the three diabetic groups. The mean daily insulin dose, maximum insulin binding capacity and total insulin binding power were significantly higher in type 1 when compared to the malnutrition modulated form of diabetes (36+/-8 vs. 26+/-11 IU/day, P<0.05; 9. 7+/-7.8 vs. 4.0+/-3.9 nmol/l, P=0.03 and 59+/-29 vs. 29+/-43, P=0.01, respectively). Insulin antibodies S.D. score and its affinity did not show significant relationship with daily insulin dose and glycemic control (HbAl) at admission. Only 24+/-7% variations in daily insulin requirement were accounted for by total insulin binding power. There was a significant inverse relationship between insulin antibody S.D. score and duration of insulin therapy (r=-0. 4172, P<0.0004). To conclude, insulin antibody response following bovine insulin therapy is not different among type 1, malnutrition modulated form of diabetes and FCP diabetes. The insulin antibody response to bovine insulin therapy does not contribute significantly to increase in daily insulin requirement in bovine insulin treated insulin requiring young diabetics.

Abstract
Tropical calcific pancreatitis (TCP) is a variant of chronic pancreatitis, occurring only in developing countries. It frequently leads to diabetes at a young age. To determine the pathogenesis of glucose intolerance, beta-cell function and insulin sensitivity were measured in 11 TCP patients with normal glucose tolerance (TCP-NGT), six TCP patients with mild hyperglycemia [TCP-DM] median fasting plasma glucose, 6.1 mmol/L), and 16 healthy control subjects. The technique of continuous infusion of glucose with model assessment (CIGMA) was used to calculate beta-cell function (%B) and insulin sensitivity (%S), based on plasma glucose and insulin levels achieved after an intravenous infusion of glucose. %S was similar in both groups of TCP patients and controls. In contrast, %B was significantly lower in TCP-DM patients (median, 53; interquartile range, 41 to 62) compared with controls (90; 65 to 143; P < .01) and with TCP-NGT patients (119; 91 to 159; P < .01). TCP-NGT and control subjects had similar beta-cell function. Among patients with TCP, %B negatively correlated with the duration of pancreatitis (r = -.63, P < .05). Our results suggest that patients with TCP develop diabetes due to a diminution in beta-cell function, and that insulin resistance does not play a significant role in its pathogenesis.
