Pancreatic Secretory Trypsin Inhibitor (SPINK1) Gene Mutation in Patients with Acute Alcohol Pancreatitis (AAP) Compared to Healthy Controls and Heavy Alcohol Users without Pancreatitis. Int J Mol Sci 2022; 23:ijms232415726. [PMID: 36555366 PMCID: PMC9778821 DOI: 10.3390/ijms232415726] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2022] [Revised: 11/27/2022] [Accepted: 12/06/2022] [Indexed: 12/14/2022] Open
Abstract
Only 3-5% of heavy alcohol users develop acute alcohol pancreatitis (AAP). This suggests that additional triggers are required to initiate the inflammatory process. Genetic susceptibility contributes to the development of AAP, and SPINK1 mutation is a documented risk factor. We investigated the prevalence of the SPINK1(N34S) mutation in patients with AAP compared to heavy alcohol users who had never suffered an episode of pancreatitis. Blood samples for the mutational analysis from patients with first episode (n = 60) and recurrent AAP (n = 43) and from heavy alcohol users without a history of AAP (n = 98) as well as from a control population (n = 1914) were obtained. SPINK1 mutation was found in 8.7% of the patients with AAP. The prevalence was significantly lower in healthy controls (3.4%, OR 2.72; 1.32-5.64) and very low in alcoholics without pancreatitis (1.0%, OR 9.29; 1.15-74.74). In a comparison adjusted for potential cofounders between AAP patients and alcoholics, SPINK1 was found to be an independent marker for AAP. The prevalence of the SPINK1 mutation is overrepresented in AAP patients and very low in alcoholics without pancreatitis. This finding may play a role in understanding the variable susceptibility to AAP found in heavy alcohol users.

Abstract
Background: Genetic factors may play an important role in the pathogenesis of acute pancreatitis. It has been observed
in various studies that the presence of risk factors alone like alcohol abuse or gall bladder stones does not lead to attacks of
pancreatitis in all the patients. This leads to assumption that genetic factors may decrease the threshold for the development of pancreatitis in
presence of one or more risk factors. We observed that there is a paucity of data regarding the role of genetics in acute pancreatitis (AP) and
recurrent acute pancreatitis (RAP) in our part of the world and we aimed at studying the prevalence of genetic mutations in such patients.
Methods: Our study intended to nd the prevalence of SPINK1 N34S (Serine protease inhibitor kazal type 1) and CaSR (Calcium sensing
receptor) gene mutations in patients of AP and RAP. A total of 50 patients and 25 age and gender matched controls entered our study. Blood
samples were obtained from all the cases and controls for routine investigations and genetic analysis. SPINK 1 N34S and CaSR gene mutation
studies were done in all the patients and controls.
Results: Alcohol (64%) followed by gallbladder stone disease (20%) was the most common aetiology of pancreatitis. SPINK 1 N34S mutation
was present in 21 patients and 2 controls whereas CaSR gene mutation was present in 13 patients and 2 controls. Patients with SPINK 1 N34S and
CaSR gene mutations were younger than the patients without these mutations. Prevalence of both SPINK1 N34S and CaSR gene mutations was
higher in patients of RAP than AP. These mutations were not associated with aetiology or severity of pancreatitis.
Conclusion: The prevalence SPINK 1 N34S and CaSR gene mutations was higher in patients of AP and RAP. Identication of these mutations
in patients of AP can help in the identication of patients who are at increased risk of recurrent attacks of AP

CaMKII/proteasome/cytosolic calcium/cathepsin B axis was present in tryspin activation induced by nicardipine. Biosci Rep 2019; 39:BSR20190516. [PMID: 31221819 PMCID: PMC6603279 DOI: 10.1042/bsr20190516] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2019] [Revised: 06/14/2019] [Accepted: 06/19/2019] [Indexed: 12/16/2022] Open
Abstract
Premature trypsinogen activation is the early event of acute pancreatitis. Therefore, the studies on the processes of trypsinogen activation induced by compounds are important to understand mechanism underly acute pancreatitis under various conditions. Calcium overload in the early stage of acute pancreatitis was previously found to cause intracellular trypsinogen activation; however, treatment of acute pancreatitis using calcium channel blockers did not produced consistent results. Proteasome activity that could be inhibited by some calcium channel blocker has recently been reported to affect the development of acute pancreatitis; however, the associated mechanism were not fully understood. Here, the roles of nicardipine were investigated in trypsinogen activation in pancreatic acinar cells. The results showed that nicardipine could increase cathepsin B activity that caused trypsinogen activation, but higher concentration of nicardipine or prolonged treatment had an opposite effect. The effects of short time treatment of nicardipine at low concentration were studied here. Proteasome inhibition was observed under nicardipine treatment that contributed to the up-regulation in cytosolic calcium. Increased cytosolic calcium from ER induced by nicardipine resulted in the release and activation of cathepsin B. Meanwhile, calcium chelator inhibited cathepsin B as well as trypsinogen activation. Consistently, proteasome activator protected acinar cells from injury induced by nicardipine. Moreover, proteasome inhibition caused by nicardipine depended on CaMKII. In conclusion, CaMKII down-regulation/proteasome inhibition/cytosolic calcium up-regulation/cathepsin B activation/trypsinogen activation axis was present in pancreatic acinar cells injury under nicardipine treatment.

An immunocapture-LC-MS-based assay for serum SPINK1 allows simultaneous quantification and detection of SPINK1 variants. Anal Bioanal Chem 2018; 410:1679-1688. [PMID: 29318362 DOI: 10.1007/s00216-017-0803-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2017] [Revised: 11/27/2017] [Accepted: 12/01/2017] [Indexed: 12/30/2022]
Abstract
Pancreatic secretory trypsin inhibitor Kazal type 1 (SPINK1) is a 6420 Da peptide produced by the pancreas, but also by several other tissues and many tumors. Some mutations of the SPINK1 gene, like the one causing amino acid change N34S, have been shown to confer susceptibility to recurrent or chronic pancreatitis. Detection of such variants are therefore of clinical utility. So far SPINK1 variants have been determined by DNA techniques. We have developed and validated an immunocapture-liquid chromatography-mass spectrometric (IC-LC-MS) assay for the detection and quantification of serum SPINK1, N34S-SPINK1, and P55S-SPINK1. We compared this method with a time-resolved immunofluorometric assay (TR-IFMA) for serum samples and primer extension analysis of DNA samples. We used serum and DNA samples from patients with acute pancreatitis, renal cell carcinoma, or benign urological conditions. With the help of a zygosity score calculated from the respective peak areas using the formula wild-type (wt) SPINK1/(variant SPINK1 + wt SPINK1), we were able to correctly characterize the heterozygotes and homozygotes from the samples with DNA information. The score was then used to characterize the apparent zygosity of the samples with no DNA characterization. The IC-LC-MS method for SPINK1 was linear over the concentration range 0.5-1000 μg/L. The limit of quantitation (LOQ) was 0.5 μg/L. The IC-LC-MS and the TR-IFMA assays showed good correlation. The median zygosity score was 1.00 (95% CI 0.98-1.01, n = 11), 0.55 (95% CI 0.43-0.61, n = 14), and 0.05 (range 0.04-0.07, n = 3) for individuals found to be wt, heterozygous, and homozygous, respectively, for the N34S-SPINK1 variant by DNA analysis. When DNA samples are not available, this assay facilitates identification of the N34S- and P55S-SPINK1 variants also in archival serum samples.

Abstract
Acute pancreatitis (AP) is a complex disease that results in significant morbidity and mortality. For many decades, it has compelled researchers to explore the exact pathogenesis and the understanding of the pathogenesis of AP has progressed dramatically. Currently, premature trypsinogen activation and NF-κB activation for inflammation are two remarkable hypotheses for the mechanism of AP. Meanwhile, understanding of the influence of genetic polymorphisms has resulted in tremendous development in the understanding of the advancement of complex diseases. Now, genetic polymorphisms of AP have been noted gradually and many researchers devote themselves to this emerging area. In this review, we comprehensively describe genetic polymorphisms combined with the latest hypothesis of pathogenesis associated with AP.

Abstract
OBJECTIVES This research was applied to case-control studies of the association between pancreatitis and SPINK1 gene to assess the joint evidence for the association, the influence of individual studies, and evidence for publication bias. METHODS MEDLINE and Embase were searched to identify longitudinal studies evaluating pancreatitis and SPINK1. Odds ratios (ORs) and 95% confidence interval (CI) were pooled using random-effect models and calculated using Carlin method. Publication bias was assessed using Egger et al's approach (A famous statistic method by Egger et al). Sensitivity, heterogeneity, and trim and fill analyses were conducted. RESULTS Based on the results, we found that (1) the results support for the association between pancreatitis and SPINK1, when analyzed totally and by subdivision (total [OR, 7.771; 95% CI, 5.232-11.543; P < 0.000]; European [OR,6.400; 95% CI, 4.346-9.426; P < 0.000]; Asian [OR, 11.823; 95% CI, 4.612-30.310; P < 0.000]; American [OR, 3.777; 95% CI, 1.596-8.939; P = 0.002]; mixed: [OR, 13.566; 95% CI, 2.322-79.252, P = 0.004]); (2) no evidence indicates that this association is accounted for by any one study, and no evidence indicates any publication bias exists. CONCLUSIONS The results indicated that SPINK1 gene, particularly the N34S mutation, has a genetic association with the development of pancreatitis.

Abstract
The Huntington's disease (HD) protein, huntingtin (HTT), is essential for early development. Because suppressing the expression of mutant HTT is an important approach to treat the disease, we must first understand the normal function of Htt in adults versus younger animals. Using inducible Htt knockout mice, we found that Htt depletion does not lead to adult neurodegeneration or animal death at >4 mo of age, which was also verified by selectively depleting Htt in neurons. On the other hand, young Htt KO mice die at 2 mo of age of acute pancreatitis due to the degeneration of pancreatic acinar cells. Importantly, Htt interacts with the trypsin inhibitor, serine protease inhibitor Kazal-type 3 (Spink3), to inhibit activation of digestive enzymes in acinar cells in young mice, and transgenic HTT can rescue the early death of Htt KO mice. These findings point out age- and cell type-dependent vital functions of Htt and the safety of knocking down neuronal Htt expression in adult brains as a treatment.

Abstract
BACKGROUND Genetic predisposition in paediatric idiopathic acute, acute recurrent pancreatitis and its consequences are unknown. We studied frequency of genetic markers in acute, acute recurrent, chronic pancreatitis and their impact on natural history. METHODS Over a period of 2 years 68 consecutive children with pancreatitis (35.3% acute, 32.3% acute recurrent, 32.3% chronic) and 25 controls were recruited in a single centre. Common mutations for serine-protease-inhibitor (SPINK1 N34S), protease-inhibitor (PRSS1 R122H) and cystic fibrosis transmembrane conductance regulator (CFTR DeltaF508, 5T) were analysed. RESULTS Mean age was 13.4±2.5 years. Overall, 30 cases (SPINK1 N34S n=26, CFTR 5T n=4) and 1 control (SPINK1 N34S) had mutations (p=0.0001). The prevalence of SPINK1 N34S mutation was similar in chronic and acute recurrent pancreatitis (45%). Six children with severe acute pancreatitis had SPINK1 N34S mutations (25%, p<0.05), and 4 were homozygous. On follow-up 5 acute pancreatitis patients with mutations and 1 without mutations developed chronic pancreatitis (p=0.004); 8 cases of acute recurrent pancreatitis progressed to chronic pancreatitis (38%); of these 66.7% had mutations vs. 16.7% who did not (p=0.03). CONCLUSIONS Almost 50% of idiopathic chronic, acute recurrent and 33% of acute pancreatitis in children are genetically predisposed. Presence of genetic mutations in acute and recurrent acute pancreatitis increases the risk of developing chronic pancreatitis.

Abstract
Background Explanation of the ultimate causes of acute and chronic pancreatitis is challenging. Hence, it is necessary to seek various etiological factors, including genetic mutations that may be of importance in triggering recurrence and progression of acute to chronic pancreatitis. The aim of this study was to determine the frequency of genetic mutations in patients with acute pancreatitis and to investigate their relationship with the etiology and clinical course. Methods The study included 221 patients treated for acute pancreatitis and 345 healthy subjects as a control group. Peripheral blood samples were collected from each study participant and genomic DNA was isolated. Genotyping of common mutations in the SPINK1 (p.N34S and p.P55S) and CTRC (p.I259V, p.V235I, p.K247_R254del, p.E225A) genes was performed using the high-resolution melting method. Mutations in the CFTR p.F508del (delF508_CTT) were genotyped using allele-specific amplification polymerase chain reaction. All detected mutations were confirmed with direct capillary DNA sequencing. Results Mutations in SPINK 1, CFTR and CTRC were detected in 6.3 %, 2.3 % and 1.8 % of patients with acute pancreatitis versus 3.2 %, 3.8 % and 1.2 % of volunteers in the control group. No relationship was found between the detected mutations and severity of acute pancreatitis: mild acute pancreatitis, mutation of CFTR in 4 (2.8 %) and CTRC in 2 (1.4 %) patients; severe acute pancreatitis, mutation of CFTR and CTRC in 1 (2.6 %) case each. The SPINK1 mutation was significantly more frequent in 8 (10.4 %) severe cases than in 6 (4.2 %) mild cases (P < 0.05), and was observed in 5/70 (7.1 %) patients with alcohol-related AP, 5/81 (6.2 %) with biliary AP, and 4/63 (6.3 %) in those without any established cause of the disease. Conclusions Mutation p.N34S in SPINK1 may predispose patients to acute pancreatitis, especially in those abusing alcohol, and may promote a more severe course of the disease.

Abstract
Integrated traditional Chinese medicine (ITCM) is known to improve health in patients with acute pancreatitis (AP); however, the molecular mechanisms underlying this effect are unknown. AP is associated with the expression of PRSS1 and SPINK1. Thus, the present study aimed to investigate whether ITCM was able to ameliorate AP by regulating the expression levels of protein, serine 1 (PRSS1) and serine peptidase inhibitor, Kazal type 1 (SPINK1). A total of 100 AP patients were divided at random into two groups. The treatment group were treated externally with a herbal ITCM preparation, while the control group received a routine placebo treatment. The mRNA and protein expression levels of PRSS1 and SPINK1 were subsequently compared between the two groups. The results revealed that the health of the patients who had received ITCM improved significantly when compared with the control group patients (P<0.05). In addition, the expression levels of PRSS1 and SPINK1 were found to be lower in the treatment group when compared with the control group (P<0.05). Therefore, ITCM exhibited a significant therapeutic effect on AP and produced no side effects since the treatment was applied externally. ITCM may ameliorate AP by downregulating the expression of PRSS1 and SPINK1; thus, should be considered as a potential therapy for the development of drugs against AP.

Abstract
OBJECTIVE The long-term morphological changes induced by a single episode of alcoholic pancreatitis are not known. Our aim was to study these morphological changes in secretin-stimulated magnetic resonance cholangiopancreatography (S-MRCP) after the first episode of alcohol-associated acute pancreatitis and to evaluate the risk factors and possible protective factors potentially associated with later chronic findings. We have previously reported 2-year follow-up results in pancreatic morphology. This study extends the follow-up to 9 years. PATIENTS AND METHODS In this prospective follow-up study, S-MRCP imaging was performed for 44 (41 M, 3 F; mean age, 46 (25-68) years) patients after their first episode of alcohol-associated pancreatitis. Pancreatic morphology was evaluated at 3 months and at 2, 7, and 9 years after hospitalization. Recurrent attacks of pancreatitis were studied and pancreatic function was monitored by laboratory tests. Patients' alcohol consumption was evaluated with questionnaires, laboratory markers, and self-estimated alcohol consumption via interview. Smoking and body mass index were annually recorded. RESULTS At 3 months, 32 % of the patients had normal findings in S-MRCP, 52 % had acute, and 16 % had chronic changes. At 7 years, S-MRCP was performed on 36 patients with normal findings in 53 %, the rest (47 %) having chronic findings. Pancreatic cyst was present in 36 %, parenchymal changes in 28 %, and atrophy in 28 % of the cases. There were no new changes in the pancreas in the attending patients between 7 and 9 years (18 patients). Of the patients with only acute findings at 3 months, 60 % resolved to normal in 7 years, but the rest (40 %) showed chronic changes later on. The initial attack was mild in 65 %, moderate in 25 %, and severe in 10 % of the patients. Patients with mild first attack had fewer chronic changes at 7 years compared to patients with moderate or moderate and severe together (p = 0.03, p = 0.01). Of the patients in the seventh year of S-MRCP, 22 % had suffered a recurrent episode of acute pancreatitis (mean, 22 (2-60) months) and 11 % had a clinical diagnosis of chronic pancreatitis. At 7 years, 88 % of the patients with recurrences had chronic findings in S-MRCP versus 36 % with nonrecurrent pancreatitis (p = 0.02). Six (17 %) patients abstained from alcohol throughout follow-up (mean, 8.7 (7-9.1) years), but even one of these developed pancreatic atrophy. Out of the non-abstinent patients who did not suffer recurrences, 4/22 (18 %) had developed new findings during at follow-up S-MRCP (NS). In univariate analysis, heavy smoking showed no correlation with increased chronic changes compared to nonsmoking. CONCLUSIONS Morphological pancreatic changes increase with recurrent episodes of acute pancreatitis. Patients with mild first attack have fewer chronic changes in the pancreas in the long term. However, even a single episode of acute alcoholic pancreatitis may induce chronic morphological changes in long-term follow-up.

Abstract
INTRODUCTION Impairment of the mucosal barrier plays an important role in the pathophysiology of acute pancreatitis. The myosin IXB (MYO9B) gene and the two tight-junction adaptor genes, PARD3 and MAGI2, have been linked to gastrointestinal permeability. Common variants of these genes are associated with celiac disease and inflammatory bowel disease, two other conditions in which intestinal permeability plays a role. We investigated genetic variation in MYO9B, PARD3 and MAGI2 for association with acute pancreatitis. METHODS Five single nucleotide polymorphisms (SNPs) in MYO9B, two SNPs in PARD3, and three SNPs in MAGI2 were studied in a Dutch cohort of 387 patients with acute pancreatitis and over 800 controls, and in a German cohort of 235 patients and 250 controls. RESULTS Association to MYO9B and PARD3 was observed in the Dutch cohort, but only one SNP in MYO9B and one in MAGI2 showed association in the German cohort (p < 0.05). Joint analysis of the combined cohorts showed that, after correcting for multiple testing, only two SNPs in MYO9B remained associated (rs7259292, p = 0.0031, odds ratio (OR) 1.94, 95% confidence interval (95% CI) 1.35-2.78; rs1545620, p = 0.0006, OR 1.33, 95% CI 1.16-1.53). SNP rs1545620 is a non-synonymous SNP previously suspected to impact on ulcerative colitis. None of the SNPs showed association to disease severity or etiology. CONCLUSION Variants in MYO9B may be involved in acute pancreatitis, but we found no evidence for involvement of PARD3 or MAGI2.

Abstract
OBJECTIVES The study's objective was to assess the association between the PRSS1 R122H and N29I and the SPINK1 N34S mutations and acute pancreatitis (AP) and recurrent pancreatitis in Mexican pediatric patients. METHODS The N34S and R122H mutations were detected using polymerase chain reaction-restriction fragment length polymorphism, and the N29I mutation was detected using allele-specific polymerase chain reaction in 92 pancreatitis patients (58 AP and 34 recurrent pancreatitis patients) and 144 controls. RESULTS We found 1 mutated allele in 4 (4.3%) of 92 pancreatitis patients and none in the controls. All 4 patients bearing mutations had AP, with a frequency of 6.8% (4/58). Three (5.2%) of 58 patients were heterozygous for the N34S mutation, and 1 (1.7%) of 58 patients was heterozygous for the N29I mutation. The comparison between the AP and control groups revealed both a significant number of patients carrying any mutations in the screened genes (P = 0.008) and bearing the N34S mutation (P = 0.023). Moreover, we found that the N34S G allele increased the risk of developing AP (odds ratio, 10.3; confidence interval, 1.1-248.8). CONCLUSIONS Patients bearing the N34S G allele exhibited a 10-fold increased risk of developing AP compared with controls, suggesting that the SPINK1 N34S mutation represents an etiologic risk factor for AP in our Mexican pediatric patients.

Abstract
OBJECTIVES Serine Protease Inhibitor Kazal type 1 (SPINK1) protects against premature intracellular activation of trypsinogen and development of acute pancreatitis. Our aim was to determine the prevalence of SPINK1 mutations (a) in unselected patients with first-time acute pancreatitis and (b) in the Danish background population (c) in a meta-analysis to combine the results with findings in similar investigations worldwide and (d) to evaluate whether patients with SPINK1 mutations had a more severe clinical course. METHODS A total of 75 consecutive patients admitted to a surgical department with first-time acute pancreatitis were prospectively included. In addition, 188 healthy controls were tested for the SPINK1 variants: p.N34S, p.P55S, p.R65Q, p.R67C, and IVS3+2 T>C, in order to calculate the prevalence of SPINK1 mutations in the Danish background population. A meta-analysis was conducted on previous studies on acute pancreatitis and SPINK1 mutations. RESULTS Two patients (2.7%) and two controls (1.1%) were heterozygous for the p.N34S variant. The meta-analysis confirmed that the p.N34S variant is overrepresented in patients with acute pancreatitis compared with the background population (OR=3.16, P<0.001). But this analysis did not clarify whether this was only true for patients with first-time acute pancreatitis or recurrent pancreatitis as the present studies do not provide this information, and those who do not have enough patients to reach levels of statistic significance, even if data are pooled. CONCLUSION The SPINK1 variant p.N34S is overrepresented in patients with acute pancreatitis, but more studies distinguishing between first-time and recurrent acute pancreatitis have to be done to determine whether this is only true for patients with recurrent acute pancreatitis.

Abstract
BACKGROUND AND AIM Previous studies have shown an association of variants in trypsin-associated genes, such as cationic trypsinogen (PRSS1) and serine protease inhibitor, Kazal type-1 (SPINK1) with pancreatitis. However, whether these genetic variants are associated with acute pancreatitis (AP) remains largely unknown, especially when the first attack is separated from recurrent attacks. METHODS A total of 261 patients with AP (174 with a sentinel attack, and 87 with recurrent attacks) and healthy controls were genotyped for the p.R122H mutation in the PRSS1 gene, p.N34S and IVS3 + 2T > C variants in the SPINK1 gene, the p.G191R variant in the anionic trypsinogen gene, the p.E32del variant in the mesotrypsinogen (PRSS3) gene, and the -2518G > A variant in the monocyte chemoattractant protein-1 gene by polymerase chain reaction-restriction enzyme digestion and direct sequencing. RESULTS Patients with recurrent attacks were younger. The proportions of biliary pancreatitis and severe cases were lower, and that of idiopathic pancreatitis was higher in patients with a sentinel attack than in those with recurrent attacks. The frequencies of the genetic variants examined did not differ between controls and patients with sentinel pancreatitis. The frequencies of the PRSS1 p.R122H mutation, SPINK1 p.N34S variant, and PRSS3 p.E32del variant, but not other genetic variants, were higher in patients with recurrent attacks than in controls or those with a sentinel attack. CONCLUSIONS The PRSS1 p.R122H mutation, SPINK1 p.N34S, and PRSS3 p.E32del variants were associated with recurrent, but not sentinel AP. The genetic background could possibly be different between sentinel and recurrent AP.

Abstract
BACKGROUND The main cause of chronic pancreatitis (CP) is excessive alcohol consumption. On the other hand, only 5-10% of heavy drinkers develop chronic pancreatitis. We have only limited information regarding the pathogenic mechanism by which alcohol leads to the disease. Mutations of the PRSS1 and SPINK 1 have been mostly implicated in hereditary and idiopathic CP, but their presence in other types of this disease have also been reported. AIMS The aim of the study was to determine the frequency of PRSS1 and SPINK1 mutations in patients with chronic alcoholic (ACP) and idiopathic pancreatitis (ICP) as well as to investigate their relation to the clinical course of the disease. METHODS The study included 33 ACP and 14 ICP patients as well 46 healthy subjects. The diagnosis of CP was based on clinical data, ultrasound, and computed tomography. After isolation of DNA from peripheral blood two trypsinogen mutations were detected N29I and R122H by allelo-specific amplification polymerase chain reaction (ASA-PCR) and by the PCR-restriction fragment length polymorphism (RFLP). Beside this N34S mutation of SPINK1 was analyzed by PCR restriction fragment length polymorphism (PCR-RFLP). RESULTS PRSS1 mutations have been detected in 11 (33%) patients with ACP. The frequency of the PRSS1 mutations was higher in patients with ACP than in controls (4.3%) (p < 0.001). The frequency of PRSS1 mutation was present in 21.4% of ICP patients, which was significantly higher (p < 0.05) than in controls. Overall, six (18%) SPINK1 mutations in ACP group have been detected. Among 14 patients with ICP, in four (28.6%) of them SPINK1 has been detected. The same mutations have also been found in three (6.5%) control subjects. The frequency of the N34S mutation was higher in patients with ICP than in the controls (p < 0.05), but the frequency of N34S mutation did not differ between ACP and the control group. No relations have been detected between PRSS1 and SPINK1 mutations presence and clinical course and complications of CP. CONCLUSIONS Those preliminary data suggest the high prevalence of SPINK1 and PRSS1 mutations in the Polish population, generally, as well as in CP patients. It may be speculated that those mutations contribute to the development of chronic pancreatitis, especially in patients with alcohol overindulgence.

Abstract
The association of alcohol consumption and acute pancreatitis (AP) has been well documented. Extensive research in the field of alcohol-induced AP has allowed scientists to understand the different aspects by which ethanol may alter pancreatic cellular function. However, despite the recognition and understanding of these proposed mechanisms, the basic question that remains unanswered is that although alcohol is consumed the world over, why is it that only some people develop AP? Epidemiologic data indicates a higher frequency of alcohol-induced AP in geographical locations where surrogate/home-brewed alcoholic beverages are freely available. These surrogate/home-brewed alcoholic beverages contain in addition to ethanol, higher alcohols (e.g. propanol and butanol) and other by-products/contaminants (e.g. acids, aldehydes and esters), the potential of which to induce pancreatic damage has been incompletely studied. Mutations in genes that metabolise alcohol as well as those that protect the acinar cells and the extra-acinar milieu from prematurely activated digestive enzymes (e.g. genetic mutations in SPINK1 or PRSS1 genes) have also been noted in these geographical locations. Based on the available epidemiologic, clinical and basic research data available at the present time, we propose a unifying hypothesis presenting for the first time the 'critical mass' concept. We hypothesise that it is the achievement of a 'critical mass' of damaged acinar cells that is required to trigger off the inflammatory cascade leading to a clinically recognised attack of AP. The consequence of a critical mass of damaged acinar cells is the generation of sufficient mediators to result in clinical AP. While the consumption of alcohol does damage acinar cells, the number of damaged acinar cells does not necessarily reach the 'critical mass' with every binge. Co-factors such a high fat or protein meals are required to sensitize the acinar cells by raising the metabolic state to a high level which compromises the viability of the cells. In addition, the existence of genetic mutations and / or the consumption of surrogate alcoholic beverages, by facilitating acinar cell damage, directly or indirectly, potentially hasten the achievement of the 'critical mass', leading to an attack of AP.

Abstract
OBJECTIVES Serine protease inhibitor Kazal type 1 (SPINK1) gene mutations have been associated with chronic pancreatitis of different etiologies; however, little is known about their role in the pathogenesis of acute pancreatitis (AP). Our aim was to study the prevalence of the SPINK1 N34S polymorphism in patients with sentinel and recurrent AP (RAP). METHODS Patients with AP were enrolled, and genetic tests were carried out to detect the SPINK1 N34S polymorphism. Subjects without pancreatitis from the North American Pancreatitis Study were used as controls. RESULTS A total of 188 patients (116 with sentinel AP and 72 with recurrent attacks) and 670 controls were evaluated. The SPINK1 N34S polymorphism was detected in 1 of 232 alleles in patients with sentinel AP, 11 of 144 alleles in patients with RAP, and in 19 of 1,340 control alleles. There was no difference in the prevalence of the polymorphism between sentinel attack patients and controls. Patients with the polymorphism were more prone to develop recurrent attacks (odds ratio (OR)=19.1, 95% confidence interval (CI): 2.4-149.6). CONCLUSIONS The SPINK1 N34S polymorphism was not associated with the sentinel AP attack, but it substantially increases the risk of recurrent attacks. Additional studies are needed to further elucidate the mechanism of SPINK1-associated protection in AP.

Abstract
The development of proteomic methods, especially mass spectrometry, has brought new possibilities to tumor marker research. Pancreatic secretory trypsin inhibitor (PSTI), a common known biomarker for various malignancies, occurs on genetic variants that we are able to detect at the protein level with proteomic techniques using immunoaffinity capture prior to liquid chromatography-mass spectrometry (LC-MS). We also show that PSTI can be detected in urine from cancer patients using a two-step peptide enrichment technique and LC-MS. These results show that tumor-associated peptides can be detected in urine by proteomic techniques.

Abstract
INTRODUCTION Pancreas susceptibility to alcohol is variable and only 5-10% of chronic alcohol abusers develop chronic pancreatitis; the role of genetic factors in this process is unknown. The CFTR gene encodes a protein that acts on epithelial cells and plays a key role in normal exocrine pancreatic function. METHODS This study investigated the frequency of polymorphisms in intron 8 of the CFTR gene in patients with alcoholic chronic pancreatitis. Three groups of patients were studied: group A - 68 adult alcoholics with a diagnosis of chronic pancreatitis; group B - 68 adult alcoholics without pancreatic disease or liver cirrhosis and group C - 104 healthy nonalcoholic adults. RESULTS T5/T7 genotype was more frequent in group A (11.8%) than in group B (2.9%) (p = 0.0481), and there was no statistical difference when groups A and C (5.8%) were compared (p = 0.1317). The haplotype combination (TG)10-T7/(TG)11-T7 was more frequent in groups B (23.5%) and C (20.2%) than in group A (7.3%) (p = 0.0080 and 0.0162). CONCLUSION There are differences when these three groups are compared and individuals with T5/T7 genotype might have a greater risk of developing chronic pancreatitis when they become chronic alcoholics.

Abstract
OBJECTIVE Acute pancreatitis (AP) is a disease whose pathogenesis remains largely obscure. Genetic research has focussed attention upon the role of the pancreatic protease/protease inhibitor system. The aim of this study was to investigate the prevalence of genetic variants of the trypsin inhibitor, SPINK1, in acute pancreatitis. METHODS We genotyped 468 patients with AP and 1117 healthy controls for SPINK1 alterations by single-strand conformation polymorphism analysis and by melting curve analysis using fluorescence resonance energy transfer probes. RESULTS The c.101A>G (p.N34S) variant was detected in 24/936 alleles of patients and in 18/2234 alleles of healthy controls (odds ratio=3.240; 95% confidence interval: 1.766-5.945; P<0.001). In the UK patients, the mean age of patients with N34S was 11.9 years younger compared with N34S negative patients (P=0.023), but this was not apparent in the German patients. Allele frequencies for the c.163C>T (p.P55S) variant did not differ between patients and controls. CONCLUSION The SPINK1 N34S variant is associated with acute pancreatitis. This supports the importance of premature protease activation in the pathogenesis of AP and suggests that mutated SPINK1 may predispose certain individuals to develop this disease.

Abstract
OBJECTIVE Primary hyperparathyroidism (pHPT)-related hypercalcemia is considered to represent a risk factor for the development of pancreatitis. We therefore explored whether mutations in genes that were previously identified to increase the risk for pancreatitis coexist in a cohort of 826 patients with pHPT prospectively studied between 1987 and 2002. METHODS Among 826 patients with pHPT, 38 patients were identified with pancreatitis (4.6%). DNA was available from 25 patients (13 women/12 men, 16 acute pancreatitis/9 chronic pancreatitis). These individuals and 50 patients with pHPT without pancreatitis were analyzed for mutations in the serine protease inhibitor Kazal type I (SPINK1) gene (N34S) and the cationic trypsinogen gene (PRSS1) (N29I, R122H) by melting curve analysis and DNA sequencing. Sequence analysis of the cystic fibrosis transmembrane conductance regulator (CFTR) gene was carried out for the detection of 36 mutations and the Tn polymorphism. RESULTS Four of 25 patients with pHPT and pancreatitis carried the N34S missense mutation in the SPINK1 gene (16%), while all 50 controls (pHPT without pancreatitis) showed no mutation in SPINK1 or PRSS1 genes (P < 0.05 vs controls, P < 0.001 vs general population). CF-causing CFTR mutations were present in four patients (P < 0.05 vs general population), while one patient carried a 5T allele. One patient was transheterozygous (SPINK1: N34S/CFTR: R553X). Mean serum calcium levels in pancreatitis patients (3.1 mmol/L) did not differ significantly from the mean of the entire cohort (3.0 mmol/L) or pHPT patients without pancreatitis (3.1 mmol/L). CONCLUSION Pancreatitis risk is approximately 10-fold elevated in pHPT, but pancreatitis occurs infrequently. This indicates an existing but minor impact of pHPT-related hypercalcemia. If pancreatitis occurs, it seems associated with genetic risk factors such as mutations in the SPINK1 and CFTR genes. In contrast, a combination of both hypercalcemia and genetic variants in SPINK1 or CFTR increases the risk to develop pancreatitis in patients with pHPT.

Abstract
BACKGROUND AND AIM The aim of this study was to assess the incidence and etiology of acute pancreatitis at a major pediatric referral center in Australia. METHODS A 10-year retrospective audit was conducted at The Royal Children's Hospital, Melbourne, Australia. All patients from 1993 and 2002 with a serum lipase level greater than three times the upper reference range and a history consistent with acute pancreatitis were included. RESULTS During the 10-year period, 279 confirmed cases of acute pancreatitis were identified. The median age at presentation was 10 years (range, 0.2-15.9). In 209 (74.9%) patients, a likely cause of acute pancreatitis was found, including trauma (36.3%), systemic disease (22.2%), metabolic (5.8%), biliary (5.4%), drugs (3.2%), or viral illness (2.2%). In the remaining 70 (25.1%) cases, the pancreatitis was deemed idiopathic. Comparing data from 1993 to 1997 with data from 1998-2002, there was a significant increase in the annual incidence of pancreatitis (24.6 +/- 2.3 vs 31.2 +/- 6 cases per year; P = 0.04). A linear regression analysis showed a strong association between the incidence and the year of diagnosis (r(2) = 0.5775, P = 0.01). This increase was mainly due to a significant rise in idiopathic disease (r(2) = 0.83, P = 0.0002) and systemic disease (r(2) = 0.41, P = 0.048), whereas the incidence of other causes of acute pancreatitis remained unchanged. CONCLUSION The incidence of acute pancreatitis in children has increased significantly over the past decade. The increase was greatest in children with idiopathic pancreatitis. It remains unclear whether this reflects a true incidence increase or improved clinical awareness.

Abstract
OBJECTIVE Mutations in the cationic trypsinogen gene (PRSS1) have been linked with hereditary pancreatitis (HP). A change in R122H in the third exon is one of the mutations most frequently associated with HP. A mutation N34S in the serine protease inhibitor Kazal type 1 gene has also been shown to be linked with HP. The purpose of this study was to report on the incidence of PRSS1 and SPINK1 mutations in a Finnish family with HP and to correlate the findings to the clinical symptoms. MATERIAL AND METHODS The study included 36 individuals from one Finnish family with HP (21 M, 15 F, median age 38 years). All individuals underwent abdominal ultrasound and laboratory tests (glucose, faecal elastase-1 test). Blood samples were taken for mutational analysis of PRSS1 (R122H, N29I and A16V) and SPINK1 (N34S). RESULTS Ten (28%) individuals were affected by mutations: the most frequent mutation was R122H, affecting 8 (22%) individuals; 2 (6%) individuals were affected by the N34S mutation and none by the other tested mutations (N29I and A16V). Four out of eight (50%) R122H-positive individuals had a diagnosis of chronic pancreatitis without other known aetiologies. Four out of five (80%) male individuals with the R122H mutation also had clinical pancreatitis, whereas none of the three mutation-positive females had any signs or symptoms of chronic pancreatitis. The two individuals with the N34S mutation did not have any signs of chronic pancreatitis. CONCLUSIONS In the investigated Finnish pedigree with HP, the PRSS1 mutation R122H is linked with chronic disease. Although the SPINK1 mutation (N34S) was also observed in two individuals, it was not linked with the disease.

Abstract
Familial adenomatous polyposis (FAP) is characterized by the development of multiple adenomatous polyps predominantly in the colon but also in the duodenum. Scattered case reports indicate that there is a risk for pancreatitis in FAP. The most likely cause of pancreatitis in FAP is obstructing ampullary adenomas. We describe 7 FAP patients who experienced one or more episodes of pancreatitis. Two patients experienced pancreatitis after endoscopic treatment of ampullary adenoma. The cause of the pancreatitis in 5 of 7 patients could not be determined, as none of the patients had obstruction of the ampulla. Furthermore, other risk factors for pancreatitis such as pancreatic serine protease inhibitor Kazal type I (SPINK1) gene mutations were ruled out. A review of literature identified 20 FAP patients who developed the first episode of pancreatitis at a mean age of 45 years (range 23-72 years). Some 55% had recurrent episodes of pancreatitis. Eight patients had (peri) ampullary adenomas or carcinomas. In most cases, the course of pancreatitis was mild with an uneventful outcome, but one patient died after an episode of acute pancreatitis.

Abstract
PURPOSE OF REVIEW As in our previous reviews, we endeavor to review important new observations in chronic pancreatitis made in the past year. Topics recently reviewed were truncated to accommodate a surge in publications on clinical aspects of chronic pancreatitis, which contained new observations or insights into new or old concepts. RECENT FINDINGS Cystic fibrosis carriers have been found to be at increased risk of pancreatitis. Autoimmune pancreatitis may belong to a multiorgan immunoglobulin G4-related autoimmune disease, and the natural history of chronic pancreatitis differs among the etiologies. Diffusion-weighted magnetic resonance imaging improves upon previous methodologies for diagnosing reduced pancreatic exocrine secretion, and fecal elastase-1 has been found to be a poor test for diagnosing pancreatic malabsorption. Visceral hyperalgesia or heightened central pain perception may contribute to pain in chronic pancreatitis. Instruments are evolving to assess quality of life in chronic pancreatitis, and fibrolytic agents have been found to have therapeutic promise. SUMMARY Researchers this past year have further characterized genetic, molecular and clinical aspects of chronic pancreatitis. Advancing the understanding of fibrogenesis, mechanisms of exocrine insufficiency, calcification, and pain and continuing development/modification of diagnostic tests should lead to improved prevention, detection and treatment of the condition. More accurate quantification of outcomes is critical for translating potential therapies from bench to bedside.

Abstract
BACKGROUND Although the analysis of genetic variability has traditionally been performed with molecular genetic techniques, the development of proteomic technology has raised the possibility of analyzing genetic variants at the protein level. This method provides additional information about posttranslational modifications and differences in expression. We used mass spectrometry to characterize 3 variants of the peptide encoded by the serine protease inhibitor Kazal type 1 (SPINK1) gene, pancreatic secretory trypsin inhibitor (PSTI). A genetic variant of PSTI, N34S, is associated with the development of pancreatitis. METHODS We used a quadrupole/time-of-flight hybrid mass spectrometer equipped with an electrospray ionization source to analyze the molecular identity of PSTI purified from the urine of 12 patients with pancreatitis and from 3 controls. We also developed a rapid small-scale capture procedure to isolate and analyze PSTI from small volumes of urine. RESULTS The mutations responsible for mass shifts of different PSTI variants could be verified. We observed differences in the expression of different variants as well as a novel proteolytic fragment of PSTI. Small-scale magnetic bead-mediated immunoaffinity chromatography PSTI enabled easy and rapid purification from small urine volumes, facilitating mass spectrometric analysis with adequate sensitivity. CONCLUSIONS Pancreatitis-related PSTI variants occurring at nanomolar concentrations in urine can be detected and quantified by immunoaffinity purification and mass spectrometry. In addition, the N34S variant occurs at higher concentrations than the wild type. This finding casts new light on the possible role of PSTI as a cause of hereditary pancreatitis.
