Plasma metabolite profiling identifies non-diabetic CP patients with metabolic alterations progressing to prediabetes prior to HbA1c.

INTRODUCTION: Diabetes (T3cDM) secondary to chronic pancreatitis (CP) arises due to endocrine dysfunction and metabolic dysregulations. Currently, diagnostic tests are not available to identify patients who may progress from normoglycemia to hyperglycemia in CP. We conducted plasma metabolomic profiling to diagnose glycemic alterations early in the course of disease. METHODS: Liquid chromatography-tandem mass spectrometry was employed to generate untargeted, targeted plasma metabolomic profiles in CP patients, controls (n=445) following TRIPOD guidelines. Patients were stratified based on glucose tolerance tests following ADA guidelines. Multivariate analysis was performed using PLS-DA to assess discriminatory ability of metabolites among stratified groups. COMBIROC, logistic regression were employed to derive biomarker signatures. AI-ML tool(Rapidminer) was employed to verify these preliminary results. RESULTS: Ceramide, lysophosphatidylethanolamine, phosphatidylcholine, lysophosphatidic acid, phosphatidylethanolamine, carnitine and lysophosphatidylcholine discriminated T3cDM CP patients from healthy controls with AUC 93%(95%CI 0.81-0.98, p<0.0001), integration with pancreatic morphology improved AUC to 100%(95%CI 0.93-1.00, p<0.0001). Lysophosphatidic acid, phosphatidylinositol and ceramide discriminated non-diabetic CP with glycemic alterations (pre-diabetic CP);AUC 66% (95% CI 0.55-0.76, p=0.1),integration enhanced AUC to 74%,(95% CI 0.55-0.88,p=0.86). T3cDM was distinguished from pre-diabetic by lysophosphatidic acid, phosphatidylinositol and sphinganine(AUC 70%; 95%CI 0.54-0.83,p=0.08), integration improved AUC to 83% (95%CI 0.68-0.93,p=0.05). CombiROC cutoff identified 75% and 78% prediabetes in validation 1 and 2 cohorts. Random forest algorithm assessed performance of integrated panel demonstrating AUC of 72% in predicting glycemic alterations. DISCUSSION: We report for the first time that a panel of metabolites integrated with pancreatic morphology detects glycemia progression prior to HbA1c in CP patients.

Success of Xenografts in Alveolar Ridge Preservation Based on Histomorphometric Outcomes.

Different xenograft approaches in alveolar ridge preservation (ARP) are essential to understand relative to their histomorphometric outcomes. Therefore, the aim of this study involved studying biomaterials of a xenograft nature that are used in ARP procedures, to compare the different approaches and evaluate their efficacy in relation to histomorphometric data. An electronic search was completed using the databases: Ovid (Medline), Google Scholar and Wiley Online Library, including a hand search for relevant articles and grey literature. Only randomised controlled trials, using xenograft biomaterials for alveolar ridge preservation procedures involving human studies, dated from 2010-2022 were included in the review. An initial search yielded 4918 articles, after application of the eligibility criteria, 18 studies were deemed eligible for inclusion in the systematic review. The two main xenograft groups found were of bovine origin and of porcine origin. The main histomorphometric outcomes evaluated included new bone percentage (N.B%) and residual graft percentage (R.G%). The mean N.B% for the bovine and porcine groups were 33.46% and 39.63% respectively and the mean R.G% for the bovine and porcine groups were 19.40% and 18.63% respectively. The current evidence suggests that the two main xenograft biomaterials used in ARP procedures after tooth extraction, which are of bovine and porcine origin, displayed effectiveness in producing new bone.

Chronic emphysematous osteomyelitis.

Emphysematous osteomyelitis (EO) is a rare and dangerous infection characterized by the presence of intraosseous gas. In this case report, a 65-year-old man with primary central nervous system lymphoma had recurrent infections and pain in his shoulders. Urine and blood cultures revealed Klebsiella pneumoniae. CT showed the formation of gas in the right humerus and left clavicle penetrating the surrounding tissues, which led to the diagnosis of EO. After several long-term antibiotic treatments, the patient underwent surgery on the right proximal humerus. Biopsy cultures revealed K. pneumoniae.

Prevalence of Hyperuricemia in Indian Population with Hypertension.

Background and objective: The prevalence rate of hyperuricemia (HU) is comparatively higher in Asian countries than in the Western regions. Patients with coexisting HU and hypertension (HTN) are at greater risk of uncontrolled HTN, metabolic syndrome, and complications. This study aims to determine the prevalence of HU in individuals with HTN from the major geographical regions across India. Materials and methods: A cross-sectional, multicentric, observational study conducted in primary and secondary care centers from urban areas across different regions in India. Primary inclusion criteria were either a history of HTN or blood pressure systolic blood pressure (SBP) ≥140 and diastolic blood pressure (DBP) ≥ 90 mm Hg. A structured Google form was circulated among the participating healthcare practitioners from various participating centers to record the demographic, clinical, and biochemical parameters of patients visiting the respective centers. The data was consolidated and analyzed using Microsoft Excel. Screening for HU among individuals with HTN was based on two criteria-(1) self-reported diagnosed history of HU or (2) based on serum uric acid (SUA) levels >7 and > 6 mg/dL for men and women, respectively. The data were analyzed and represented using GraphPad Prism version 9. Results: Among the study population from 12 participating centers across different regions in India, 1,528 individuals had HTN. The mean age of the study participants was 57.4 ± 10.5 years with a male-to-female ratio of 1:1. The total prevalence rate of HU among individuals with HTN is 22.5% (N = 345). Gender-wise analysis indicated that 51.5% (177) of the males and 48.5% (168) of the females had HU. Among the patients with HTN and HU, 75% were overweight with a body mass index (BMI) of ≥25 kg/m2. The region-wise prevalence rate HU are North-17.4% (60), South-18% (62), Central-12.2% (42), East-29.6% (102), and West-22.9% (79). Conclusion: India's overall HU prevalence rate (22.5%) was comparable to that in other Asian countries (10-30%). However, the prevalence of HU among HTN patients varies between different regions of India (12.2-29.6%). Results from the participating centers located in an urban setting indicated that the eastern region had the highest HU prevalence (29.6%) and the Central region had the lowest HU prevalence rate (12.2%). The varying prevalence rate can be attributed to the diversity in geographical factors, genetic background or (family history of HU), sociocultural habits, and metabolic perturbations. Understanding this prevalence rate diversity can help strengthen the HU prevention measures to improve quality of life. How to cite this article: Patni B, Singh AN, Singh NK, et al.

Endoscopic sleeve gastroplasty - minimally invasive treatment for non-alcoholic fatty liver disease and obesity.

INTRODUCTION: Adequate weight loss can lead to reduction in steatosis, inflammation, and fibrosis in patients with obesity and non-alcoholic fatty liver disease (NAFLD). We evaluated the role of endoscopic sleeve gastroplasty (ESG) in patients with obesity and NAFLD. METHODS: In this single-center prospective study, consecutive adult patients with NAFLD who underwent ESG between November 2018 and May 2019 were included. The primary outcome was the impact of ESG on hepatic parameters: change in alanine aminotransferase (ALT), hepatic steatosis index (HSI), NAFLD fibrosis score (NFS), fibrosis-4 index (FIB-4), and aspartate aminotransferase (AST)-to-platelet ratio index (APRI) from baseline to 6 and 12 months. Secondary outcomes included change in glycated hemoglobin (HbA1c), percentage weight loss, and safety. Analysis of variance with repeated measures was used for statistical analysis. RESULTS: A total of 26 patients (mean age [SD] 41.5 [9.58] years; 16 females) with mean (SD) weight of 99.43 (21.89) kg at baseline were included. There was significant improvement in ALT (mean ± SD) from baseline of 59.54 ± 17.02 IU/L to 49.50 ± 11.72 IU/L and 48.42 ± 13.22 IU/L at 6 and 12 months (p = 0.001). Mean (SD) NFS was significantly improved from 0.228 (1.00) at baseline to -0.202 (1.16) and -0.552 (1.08) at 6 and 12 months (p 0.001). Mean (SD) HSI, FIB-4, and APRI scores significantly reduced from baseline to 6 and 12 months (p = 0.001). There was 18.07% total body weight loss at 12 months, with significant improvement in HbA1c. There were no major adverse events. CONCLUSION: ESG is a safe and effective treatment option for patients with NAFLD and obesity causing significant weight loss. Rigorous randomized trials are required to incorporate ESG in NAFLD treatment algorithm.

Initiation of and persistence with P2Y12 inhibitors in patients with myocardial infarction according to revascularization strategy: a nationwide study.

BACKGROUND: We aimed to analyse initiation of and persistence with P2Y12 inhibitors after first-time myocardial infarction (MI). METHODS AND RESULTS: Using Danish nationwide registries, we identified patients ≥30 years with first-time MI during 1 January 2005-30 June 2016 and subsequent prescriptions of P2Y12 inhibitors. Independent factors related to initiation of and persistence with P2Y12 inhibitors were analysed by multivariable logistic regression and a Cox proportional hazards model. Patients were stratified by revascularization strategy: percutaneous coronary intervention (PCI), coronary artery bypass graft (CABG), or medical therapy alone (MTA). Overall, 79 597 MI patients were included with 39 172 undergoing PCI, 2619 CABG, and 16 640 MTA, showing initiation of P2Y12 inhibitors of 93.4%, 49.0%, and 51.5%, respectively. Congestive heart failure, cerebrovascular disease, cardiac dysrhythmias, renal failure, previous bleeding, and oral anticoagulants were associated with less initiation of P2Y12 inhibitors. Female sex was associated with less initiation of P2Y12 inhibitors following MTA. MTA, coronary angiography, cerebrovascular disease, diabetes with complications, previous bleeding, antidiabetics, and ticagrelor as P2Y12 inhibitor were associated with non-persistence, whereas female sex, advanced age, and concomitant pharmacotherapy with angiotensin-converting enzyme inhibitors, beta-blockers, statins, oral anticoagulants, and aspirin were associated with high persistence. CONCLUSION: Initiation of P2Y12 inhibitors in PCI-treated MI patients was high in contrast to those treated with CABG or MTA and patients with certain comorbidities. Further studies on the benefit-risk ratio of P2Y12 inhibitors in CABG-treated or MTA-treated patients and patients with comorbidities after first-time MI are warranted, as is focus on persistence among patients receiving MTA, patients with comorbidities, and users of ticagrelor.

The gut microbiome in pancreatogenic diabetes differs from that of Type 1 and Type 2 diabetes.

We hypothesized that the gut microbiome in patients with diabetes secondary to chronic pancreatitis (Type 3c) is different from those with Type 1 and Type 2 diabetes. This was a cross-sectional preliminary study that included 8 patients with Type 1, 10 with Type 2, 17 with Type 3c diabetes and 9 healthy controls. Demographic, clinical, biochemical, imaging and treatment data were recorded and sequencing of the V3-V4 region of the bacterial 16SrRNA was done on fecal samples. Bioinformatics and statistical analyses was performed to evaluate the differences in the diversity indices, distance matrices, relative abundances and uniqueness of organisms between the types of diabetes. There was significant difference in the species richness. Beta diversity was significantly different between patients with Type 3c diabetes and the other groups. 31 genera were common to all the three types of diabetes. There was significant differences in the species level taxa between Type 3c diabetes and the other groups. The unique bacterial species signature in Type 3c diabetes compared to Type 1 and Type 2 diabetes included Nesterenkonia sp. AN1, Clostridium magnum, Acinetobacter lwoffii, Clostridium septicum, Porphyromonas somerae, Terrabacter tumescens, and Synechococus sp.

Pancreas Divisum Increases the Risk of Recurrent Acute Pancreatitis in Patients with rs12338 Polymorphism in the Cathepsin B Gene.

OBJECTIVES: Pancreas divisum (PD) as a cause of pancreatitis has been debated. In this study, we report the association of multiple gene polymorphisms on the risk of RAP in the presence of PD. DESIGN: We enrolled 687 individuals (167 IRAP, 276 ICP, and 244 unrelated healthy controls) from May 2015 to September 2016. Patients were divided into those with/without PD. Associations between the significantly prevalent SNPs and IRAP/ICP in the presence of PD were evaluated. Clinical data were analyzed using Mann-Whitney U/Chi-square test. Effect size of association of SNPs with IRAP/ICP was expressed as odds ratio (OR) (95% CI). Gene-gene interaction was assessed by transheterozygosity analyses. Bonferroni-corrected two-tailed "p" value of ≤ 0.01 was considered statistically significant. RESULTS: Thirty-three (19.8%) and 82 (29.7%) patients with IRAP and ICP, respectively, had PD. Among the patients with IRAP, duration of disease was significantly shorter in those with PD compared to those without (mean [95% CI] duration: 1.6 (1.3-1.9) vs 2.7 (2.3-3.1) years; p = 0.005). There were no differences in gender, race, and diabetes among patients with/without PD in IRAP/ICP groups. Mean (95% CI) pancreatic duct diameter (mm) was significantly higher in the presence of PD in patients with both IRAP [1.6 (1.4-1.9) v/s 1.29 (1.2-1.4); p = 0.03)] and ICP [5.2 (4.5-5.9) v/s 4.5 (3.9-5.1); p = 0.02]. CTSB (rs12338) polymorphisms were significantly associated with IRAP [OR (95% CI) 2.44 (1.41-4.22); p = 0.001] among patients with PD. No association was observed with ICP. Transheterozygosity analysis did not show any significant associations of combination of SNPs with IRAP in the presence of PD. CONCLUSION: Risk of RAP due to PD increases in patients with rs12338 polymorphism in the cathepsin B gene.

Risk factors for development of endocrine insufficiency in chronic pancreatitis.

Endocrine insufficiency is a common and frequent complication of chronic pancreatitis. Identifying the role of pancreatic damage in the development of diabetes is important for early identification and appropriate management. METHODS: All consecutive CP patients between January 2019 and May 2020 were retrospectively studied. Relevant statistical tests were performed. A two sided p value < 0.05 was considered statistically significant. RESULTS: Total 587 chronic pancreatitis patients were included of which 118 (20.1%) patients developed diabetes with duration of 12 (IQR 4-48) months. Older age (OR 1.079; 95% CI 1.045-1.113; p < 0.001), presence of pancreatic parenchymal (OR 2.284; 95% CI 1.036-5.038; p = 0.041) and ductal (OR 2.351; 95% CI 1.062-5.207; p = 0.035) calcifications, exocrine insufficiency (OR 6.287; 95% CI 2.258-17.504; p < 0.001), and pancreatic duct stricture (OR 3.358; 95% CI 1.138-9.912; p = 0.028) were independently associated with development of diabetes mellitus in chronic pancreatitis patients. On cox-regression analysis, smoking (HR 2.370; 95% CI 1.290-4.354; p = 0.005) and pancreatic ductal calcification (HR 2.033; 95% CI 1.286-3.212; p = 0.002) were independently associated with earlier onset of diabetes mellitus in patients with chronic pancreatitis. CONCLUSION: Pancreatic calcification, pancreatic duct stricture and pancreatic exocrine insufficiency are associated with development of diabetes mellitus in chronic pancreatitis indicating disease progression. Smoking is the modifiable risk factors associated with early onset of diabetes mellitus in CP patients.

Genetic Evaluation of Children with Idiopathic Recurrent Acute Pancreatitis.

OBJECTIVES: Several genetic risk factors have been identified in adults with idiopathic acute recurrent pancreatitis (IARP). However, the literature regarding the genetics of IARP is sparse in children. In this study, we aimed to analyze the genetic risk factors in children with IARP. METHODS: All children (< 18 years) with ARP from January 2015 to May 2018 were prospectively enrolled in the study. Children with a known cause of ARP like obstructive, toxic/metabolic, and autoimmune were excluded from the final analysis. Children with IARP underwent genetic testing for mutations/polymorphisms in genes known to predispose to pancreatitis including cationic trypsinogen protease serine 1 (PRSS1), serine protease inhibitor Kazal type 1 (SPINK1), cystic fibrosis transmembrane conductance regulator gene (CFTR), chymotrypsin C (CTRC), claudin-2 (CLDN2) and cathepsin B (CTSB). RESULTS: A total of 239 children (116 boys, 10.3 ± 3.7 years) were enrolled during the study period. Of these, 204 (85.35%) children were identified as IARP. The mean age of symptom onset and the number of pancreatitis episodes were 8.3 ± 3.7 years and 3.3 ± 1.8, respectively. A family history of pancreatitis was noted in 4.6% children. Mutations/polymorphisms in at least 1 gene were identified in 89.5% (129/144) children including SPINK1 in 41.9%, PRSS1 (rs10273639) in 58.2%, CTRC in 25.6%, CTSB in 54.9%, CLDN2 in 72.9%, and CFTR in 2.3%. There was no significant incidence of genetic mutations/polymorphisms in IARP with or without pancreas divisum (95.7 vs 88.4%; p = 0.467). CONCLUSIONS: Genetic alterations are present in the majority of the children with IARP. The incidence of genetic mutations is similar in children with or without pancreas divisum.

Reduced pancreatic polypeptide response is associated with early alteration of glycemic control in chronic pancreatitis.

AIM: To study the incidence of glucose intolerance in CP patients without diabetes by performing oral glucose tolerance test (OGTT). METHODS: We screened consecutive Indian CP patients without diabetes over 6 months by performing OGTT and correlated with physical characteristics and glycated hemoglobin (HbA1c). We also compared c-peptide and pancreatic polypeptide response in different groups based on OGTT. Relevant statistical tests were performed. P < 0.05 was considered significant. RESULTS: Total of 171 patients were screened. Mean duration of CP was 5.03 ± 4.32 years. 55 were detected to have prediabetes and 40 DM on OGTT. CP patients with diabetes and prediabetes had significantly dilated pancreatic duct compared to non-diabetic CP (4.2 ± 2.7 mm, 3.6 ± 2.7 mm, 2.84 ± 2.25 mm; p = 0.018). Fasting blood glucose (FBS) and 2-hour OGTT were 109.35 ± 19.06, 97.47 ± 11.94, 85.24 ± 9.95 and 236.13 ± 31.42, 154.65 ± 19.53, 112.89 ± 16.32 in patients with DM, prediabetes and CP patients without diabetes (p < 0.0001). There was a good c-peptide response (p = 0.001) and reduced pancreatic polypeptide response (p = 0.003) in CP patients compared to controls. CONCLUSION: Early in the course of disease reduced pancreatic polypeptide response in the presence of good c-peptide response may result in development of DM.

Nursing Home Admission and Initiation of Domiciliary Care Following Infective Endocarditis.

BACKGROUND: Infective endocarditis (IE) may cause debilitating physical and mental changes that can interfere with activities of daily living. Admission to a nursing home and need for domiciliary care following hospitalization for IE represent such relevant outcomes, yet no such data have been reported. METHODS: Using Danish nationwide registries, we identified all patients discharged alive after a first-time IE hospitalization in the period 1996 to 2014. These were matched by age, sex, calendar year, and relevant comorbidities with the background population in a 1:1 ratio. The 1-year rate of nursing home admission and initiation of domiciliary care, respectively, were assessed by multivariable Cox regression analyses. RESULTS: In total, 4,493 IE patients were matched with 4,493 control subjects from the background population (median age: 66.8 years; interquartile range: 54.1, 76.7; 67.8% men). The 1-year incidence of nursing home admission was significantly higher among IE patients compared with the matched population (3.4% vs. 1.0%; hazard ratio: 7.95; 95% confidence interval: 4.00-15.77). Furthermore, IE patients had an increased use of domiciliary care compared with the matched population (6.6% vs. 2.1%; hazard ratio: 4.39; 95% confidence interval: 2.74-7.05). Factors associated with an increased risk of nursing home admission and domiciliary care among IE patients included older age, living alone, longer length of hospital stay, cardiovascular comorbidities, and stroke during admission. CONCLUSIONS: Patients who survived IE had an 8× higher incidence of nursing home admission and a 4× higher incidence of initiation of domiciliary care than their counterparts from the matched population.

Incidence of infective endocarditis in patients considered at moderate risk.

AIMS: Stratification of patients at risk of infective endocarditis (IE) remains a cornerstone in guidance of prophylactic strategies of IE. However, little attention has been given to patients considered at moderate risk. METHODS AND RESULTS: Using Danish nationwide registries, we assessed the risk of IE in patients with aortic and mitral valve disorders, a cardiac implantable electronic device (CIED), or hypertrophic cardiomyopathy (HCM) and compared these patient groups with (i) controls from the background population using risk-set matching and (ii) a high-risk population (prosthetic heart valve). Cumulative incidence plots and multivariable adjusted Cox proportional hazard analysis were used to compare risk of IE between risk groups. We identified 83 453 patients with aortic or mitral valve disorder, 50 828 with a CIED, and 3620 with HCM. The cumulative risk of IE after 10 years was 0.9% in valve disorder, 1.3% in CIED, and 0.5% in HCM patients. Compared with the background population, valve disorder, CIED, and HCM carried a higher associated risk of IE, hazard ratio (HR) = 8.75 [95% confidence interval (CI) 6.36-12.02], HR = 6.63 (95% CI 4.41-9.96), and HR = 6.57 (95% CI 2.33-18.56), respectively. All three study groups were associated with a lower risk of IE compared with high-risk patients, HR = 0.27 (95% CI 0.23-0.32) for valve disorder, HR = 0.28 (95% CI 0.23-0.33) for CIED, and HR = 0.13 (95% CI 0.06-0.29) for HCM. CONCLUSIONS: Heart valve disorder, CIED, and patients with HCM were associated with a higher risk of IE compared with the background population but have a lower associated risk of IE compared with high-risk patients.

Bach2 repression mediates Th17 cell induced inflammation and associates with clinical features of advanced disease in chronic pancreatitis.

OBJECTIVES: Altered immune homeostasis and involvement of T cells has been reported in chronic pancreatitis (CP). We evaluated the role of Bach2 (BTB and CNC homology basic leucine zipper transcription factor 2), a key regulator of immune homeostasis in the chronicity of CP. METHODS: Expression of Bach2 and T-cell transcription factors, enumeration of BACH2+/CD4+ T-lymphocytes were performed by qRT-PCR and flow cytometry respectively. Bach2silenced human CD4+ T-lymphocytes were exposed to CP tissue extract to assess T-cell lineage commitment. Aryl hydrocarbon receptor (Ahr) and Deubiquitinase enzyme A (DUBA/OTUD5gene) were evaluated as markers of persistent Th17 cell differentiation. Bach2 gene (exons) was sequenced to identify risk variants and functionally validated. RESULTS: Decrease in Bach2 (p < 0.0001) and increase (p < 0.001) in TBX21, RORC, Ahr, PRDM1, IL23R mRNA were noted in pancreatic tissues, while BACH2+/CD4+ T-lymphocytes were decreased (p < 0.01) in circulation and tissues. Exposure of Bach2 silenced CD4+ T-lymphocytes to CP tissue extract showed increased Ahr, decreased OTUD5, and enhanced Th17 cell differentiation. Sequencing of Bach2 gene revealed association of novel variant (rs9111 in 5'-UTR) with advanced disease and luciferase assay confirmed its role in Bach2 repression. CONCLUSION: Bach2 repression mediates Th17 cell induced inflammation and rs9111-TT in individuals with primary genetic susceptibility to CP is associated with clinical features of advanced disease.

PRSS1 (R122H) mutation in an Indian family with low penetrance is associated with pancreatitis phenotype.

Mutations in PRSS1 gene namely R122H and N29I cause hereditary pancreatitis. They are autosomal dominant with a high penetrance (80%) reported in North American, North-east Asian, and North European ethnicities. However, the mutations are reportedly absent in Indian, African, and South American ethnicities. We report here for the first time a family from India that is positive for R122H mutation in the PRSS1 gene. The proband is symptomatic with chronic pancreatitis, however, the father although heterozygous for R122H is asymptomatic.

Clinical Profile and Outcome of Parathyroid Adenoma-Associated Pancreatitis.

BACKGROUND: Primary hyperparathyroidism due to parathyroid adenoma presenting with pancreatitis as the initial manifestation is rare. The causal relationship between pancreatitis and primary hyperparathyroidism is debatable. OBJECTIVE: To study the clinical and biochemical profile of patients with parathyroid adenoma-associated pancreatitis as well as the outcome following parathyroidectomy. METHODS: The authors retrospectively studied the clinical and biochemical parameters of patients with acute, recurrent acute and chronic pancreatitis who underwent parathyroidectomy for parathyroid adenoma at Asian Institute of Gastroenterology, Hyderabad, India, between April 2010 and June 2016. RESULTS: Of the total 3962 patients who presented with recurrent acute and chronic pancreatitis, 77 (1.94%) patients had parathyroid adenoma-associated pancreatitis and were included in this study for further analysis. Of these, 41 (53.2%) had recurrent acute pancreatitis and 36 (46.8%) had chronic pancreatitis. Serum calcium (12.4 ± 1.7 mg/dl) and parathyroid hormone levels (367 ± 286.4 pg/ml) were found to be elevated. Left inferior parathyroid adenoma (37.7%) was the most common finding on neck imaging. Patients with chronic pancreatitis had a longer disease duration (3.8 ± 5 years) and more pain episodes (10.7 ± 10.2) than those with recurrent acute pancreatitis (0.62 ± 0.7 years and 2.6 ± 2.7, respectively) (P = 0.0001). In all the patients, following parathyroidectomy, there was a significant decrease in serum calcium (12.4 ± 1.7 mg/dl vs. 9.7 ± 1.9 mg/dl; P = 0.0001) and serum parathyroid hormone levels (367 ± 286.4 pg/ml vs. 116.4 ± 47.1 pg/ml; P = 0.0001) as well as there was a reduction in the number of episodes and severity of pain. CONCLUSIONS: Estimating serum calcium after an episode of unexplained pancreatitis is important and can help minimize delay in diagnosing primary hyperparathyroidism, and possibly prevent the progression of pancreatitis. Parathyroidectomy improves the clinical outcome of primary hyperparathyroidism and prevents further attacks of pancreatitis.

Hereditary Persistence of Alpha-Fetoprotein Is Associated with the -119G>A Polymorphism in AFP Gene.

Alpha-fetoprotein (AFP) is a glycoprotein that is produced by the liver and yolk sac during fetal development. Its levels are usually raised in malignant conditions. Hereditary persistence of AFP (HPAFP) is a rare benign condition with elevated levels of AFP. It is inherited in a dominant mode with complete penetrance and is usually not associated with any clinical disability. We report two individuals with elevated levels of AFP harboring the -119G>A polymorphism in the AFP gene. A genetic screening to rule out variants in the AFP gene is advised in cases with unexplained persistent AFP levels to avoid inappropriate treatment and surgical options.
