Fibrocalculous pancreatic diabetes (FCPD) is a form of diabetes secondary to chronic pancreatitis that is found in tropical countries. Most patients with FCPD are lean and many are frankly undernourished. Four patients with FCPD who were obese are reported in this paper and this is the first report of obesity in FCPD patients.

Fibrocalculous pancreatic diabetes (previously known as tropical pancreatic diabetes) is a rare cause of diabetes confined to countries within the tropical belt. The aetiology of fibrocalculous pancreatic diabetes is thought to be environmental although the agent(s) is unknown. We have investigated a possible genetic basis of this disease by looking for restriction fragment length polymorphisms of genes implicated in the aetiology of diabetes mellitus. Seventy-six Dravidian patients with fibrocalculous pancreatic diabetes were studied, and the restriction fragment length polymorphisms obtained compared to racially matched control subjects (n = 94), patients with Type 2 (non-insulin-dependent) diabetes (n = 87) and Type 1 (insulin-dependent) diabetes (n = 58). No association of fibrocalculous pancreatic diabetes was found with restriction fragment length polymorphisms of the insulin receptor gene. Although no association of fibrocalculous pancreatic diabetes was found with polymorphism of the HLA DR alpha/DQ alpha/DX alpha genes, an association was found with the Taq 1 restriction fragment length polymorphisms of the DQ beta gene (DQ beta T2/T6 present in 39% of patients with fibrocalculous pancreatic diabetes compared to 19% in control subjects; p = 0.01; corrected p value = 0.04) which is similar to that found in Type 1 but not Type 2 diabetes. An association of fibrocalculous pancreatic diabetes was also found with the hypervariable region in the 5-prime flanking region of the insulin gene; 40% of patients possessed the class 3 allele compared to 9.5% of control subjects p = 0.0001; corrected p value = 0.0008).(ABSTRACT TRUNCATED AT 250 WORDS)

Fibrocalculous pancreatic diabetes (FCPD) is a form of diabetes seen in tropical countries. It is secondary to chronic, calcific, non-alcoholic pancreatitis. FCPD is usually a disease of youth. This paper reports on two elderly onset cases of FCPD. Macrovascular complications are usually rare in FCPD patients. These two patients had evidence of macrovascular diseases probably due to the older age group of the patients.

Fibrocalculous pancreatic diabetes (FCPD) is a form of diabetes secondary to chronic, non-alcoholic pancreatitis in tropical countries. Being a secondary form of diabetes, vascular complications are believed to be rare. In this paper we present two case reports of macrovascular complications (myocardial infarction and gangrene). This shows that large vessel disease does occur in FCPD.

Fibrocalculous pancreatic diabetes of the tropics has not been previously identified in Papua New Guinea where the prevalence of Type 2 (non-insulin-dependent) diabetes is increasing. Four patients with this syndrome:--onset of diabetes before the age of 30 years, low body mass index, radiologic pancreatic calcification and marked hyperglycaemia with resistance to ketosis were recognized over three years at Port Moresby General Hospital. Two patients had a history of recurrent abdominal pain in childhood, and two patients had documented insulin requirement greater than 1.5 U/kg daily, and insulin resistance confirmed by intravenous insulin tolerance test. Plasma C-peptide was present in the three cases tested. In the two patients tested islet cell antibodies were not detected but in both there was a prominent diffuse acinar stain suggestive of antibodies to acinar tissue.

Fibrocalculous pancreatic diabetes (FCPD) is a form of diabetes secondary to tropical calcific pancreatitis (TCP). The usual age of onset of FCPD is between 15 and 50 years. This paper reports on two unusual cases of FCPD with age of onset below 5 years. This is the first report of FCPD in infancy and raises intriguing questions about the rapidity with which calcification occurs in this entity.

Fibrocalculous pancreatic diabetes (FCPD) is a form of diabetes associated with tropical chronic calcific pancreatitis, seen mostly in developing countries. FCPD is likely to be a multifactorial disease with both environmental and genetic components. The reg 1A gene encodes a protein associated with regeneration of pancreatic islets and has a sequence identical to that of pancreatic stone protein. Since FCPD is associated with both diabetes and pancreatitis, we tested the hypothesis that FCPD may be the result of mutations in the coding regions of the reg 1A gene. Restriction length polymorphisms (RFLPs) and possible sequence variants of the reg 1A gene were studied by RFLP analysis, looking for single-stranded conformational polymorphisms (SSCPs) and direct nucleotide sequencing. In 20 patients with FCPD and 20 control subjects, no RFLPs were detected using 10 restriction enzymes. In 50 patients with FCPD and 50 control subjects, no SSCP variants were detected. Finally, direct nucleotide sequencing of the reg 1A gene from 30 patients with FCPD did not show any differences from the published human reg 1A gene sequence. In conclusion, it seems unlikely that mutations in the coding region of the reg 1A gene are a common cause of FCPD.

Fibrocalculous pancreatic diabetes (FCPD) is a type of diabetes secondary to tropical chronic non-alcoholic pancreatitis. Little is known about the aetiopathogenesis of FCPD. We studied glutamic acid decarboxylase antibodies (GAD-Ab) and islet cell antibodies (ICA) in patients with FCPD and compared the results with Type 1 (insulin dependent) diabetes mellitus, Type 2 (non-insulin-dependent) diabetes mellitus and non-diabetic subjects in Southern India. The prevalence of GAD-Ab was 7.0% (95% Confidence Interval (CI) 1.9-17.2) in FCPD, 47.5% (CI 31.4-64.0) in Type 1 (p < 0.001 compared to FCPD), 5.6% (CI 1.5-13.9) in Type 2 (non-significant (NS) compared to FCPD) and 0% in controls. The prevalence of ICA was 6.3% (CI 1.2-17.4) in FCPD, 53.8% (CI 37.1-70.0) in Type 1 (p < 0.001 compared to FCPD), 9.9% (CI 4.0-19.4) in Type 2 (NS compared to FCPD) and 4.7% (CI 0.4-16.1) in controls. The data suggest that in FCPD, the frequency of auto-antibodies is low and its aetiology is probably not linked to autoimmunity in the majority of the patients.

Fibrocalculous pancreatic diabetes (FCPD) is a unique form of diabetes secondary to chronic pancreatitis seen in developing countries of the world associated with either overt protein-calorie malnutrition or, more likely, with deficiency of certain micronutrients. FCPD affects young individuals and runs an aggressive course to reach the endpoints of diabetes, pancreatic calculi and exocrine pancreatic dysfunction (steatorrhoea) in the majority of cases. There are characteristic features of FCPD radiologically, ultrasonographically, on endoscopic retrograde cholangiopancreatography and on histopathology which distinguish it from chronic pancreatitis of other aetiologies seen in temperate zones, e.g. alcoholic chronic pancreatitis. Although a secondary form of diabetes, specific diabetes-related complications like retinopathy and nephropathy do occur in FCPD. There appears to be a high risk of developing pancreatic carcinoma. Although the aetiology of FCPD is still unclear, the role of micronutrient (antioxidant) deficiency is emerging as a possible aetiological or predisposing factor. The contribution of genetic factors and environmental toxins, e.g. cyanogenic glycosides or other nutritional/toxic factors, merit further study. Studies on FCPD, a good model of a secondary form of diabetes, could lead to improved understanding of other primary forms of diabetes as well. If the underlying aetiological factors are identified, it may also be possible to prevent this type of diabetes.

Fibrocalculous pancreatic diabetes (FCPD) is an uncommon cause of diabetes, seen mainly in developing countries. A family-based study was carried out in 67 Bangladeshi families, consisting of a proband with FCPD and both parents, to determine whether an association exists between FCPD susceptibility and either the major histocompatiblity complex (MHC) or insulin gene (INS) loci. HLA-DQB1 typing was done using allele-specific primers, and INS was typed using the restriction enzyme HphI. Three microsatellites (TNFa, TNFc and TNFd), from within and flanking the TNF-LT locus, were used for MHC Class IV typing and a PCR-RFLP assay was used to define the -308G/A TNF promoter polymorphism. The extended transmission disequilibrium test (ETDT) was used for statistical analysis. An overall association was observed between FCPD and HLA-DQB1 (P = 0.003), that was largely due to a positive association with HLA-DQB1*0302 and a negative association with HLA-DQB1*0202. Although no association was found between FCPD and TNF-LT microsatellite markers a trend was observed for TNFc (P = 0.037, Pc = 0.15). No association was found between FCPD and INS (P = 0.26). This study confirms an association between FCPD and the MHC using a family-based study design and the stringent ETDT analysis; a novel protective association was found with HLA-DQB1*0202 in Bangladeshi FCPD subjects. The genetic susceptibility to FCPD has features both similar and dissimilar to T1DM.
