Prevalence of primary painless chronic pancreatitis: A systematic review and meta-analysis. Pancreatology 2022; 22:20-29. [PMID: 34840065 PMCID: PMC8785146 DOI: 10.1016/j.pan.2021.11.006] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2021] [Revised: 11/12/2021] [Accepted: 11/15/2021] [Indexed: 01/03/2023]
Abstract
BACKGROUND/OBJECTIVES While pain is the predominant symptom of chronic pancreatitis (CP), a subset of patients may experience a painless course. This systematic review aimed to determine the prevalence of primary painless CP. METHODS MEDLINE (PubMed), EMBASE and Web of Science Core Collection databases were searched for published studies through September 15, 2020 that included at least 10 consecutive patients with CP and which reported the number with painless CP. The presence of a history of recurrent acute pancreatitis (RAP), exocrine pancreatic insufficiency (EPI), diabetes mellitus (DM) and pancreatic adenocarcinoma (PA) in the painless CP patients was also recorded. A random effects model was used to determine pooled prevalence estimates with 95% confidence intervals (95% CI). RESULTS Among the 5057 studies identified and screened, 42 full-text articles were included in the final analysis. There were a total of 14,277 patients with CP among whom 1569 had painless CP. The pooled prevalence of painless CP was 12% (95% CI 10-15%). Among a subset of studies that reported on calcifications (n = 11), DM (n = 12), EPI (n = 8) and history of RAP (n = 14), the pooled prevalence estimates were 96% (95% CI 73-100%), 51% (95% CI 32-70%), and 47% (95% CI 15-81%), respectively. Alcohol, idiopathic/genetic and other etiologies were attributed to be the cause of painless CP in 32.4%, 56.9% and 8.9% patients, respectively. CONCLUSION Approximately one in ten patients with CP have primary painless disease with the majority being attributable to an idiopathic/genetic etiology. Further research is needed to determine the optimal management of these patients.

Abstract
Fibrocalculous pancreatic diabetes (FCPD) is a unique form of diabetes reported from tropical countries, associated with both endocrine and exocrine disease of the pancreas. The pre-diabetic phase of the disease is called tropical chronic pancreatitis (TCP). Currently FCPD is classified as a secondary form of diabetes called pancreatic diabetes, because essentially the disease is caused by pancreatic damage. There is an overlap of these subjects with idiopathic, non-alcoholic pancreatitis. This review will cover the etiopathogenesis, diagnosis and management of this clinical condition. FCPD could lead to endocrine dysfunction (diabetes and its complications) as well as exocrine dysfunction, and is associated with a higher risk of pancreatic cancer, for which early detection is important.

Abstract
Fibrocalcific pancreatic diabetes (FCPD) is a rare form of diabetes affecting people in the tropics and presenting with unique clinical and radiological features. The onset of diabetes usually follows the first few episodes of abdominal pain and develops by the second or third decade of life. Endocrine and exocrine pancreatic insufficiency, brittle glycemic control, and insulin-requiring, ketosis-resistant diabetes are the novel characteristics of FCPD. The etiopathogenetic mechanisms leading to FCPD remain unknown. Although defects in insulin secretion are the major contributors, growing evidence towards a possible role for insulin resistance and body composition abnormalities have added a new dimension to the disease pathogenesis. Deciphering the key pathogenetic mechanisms may have a profound effect on therapeutic strategies in future studies on FCPD.

Abstract
OBJECTIVE To study the clinical characteristics of newly diagnosed diabetic patients in tropical Africa. DESIGN Prospective study of all newly diagnosed diabetic patients registered at a major urban hospital between 1 June 1981 and 31 May 1987. SETTING Muhimbili Medical Centre, Dar es Salaam, Tanzania. PATIENTS 1250 Patients: 874 men, 376 women. RESULTS 272 (21.8%) Patients had diabetes requiring insulin, 825 (66.0%) had diabetes not requiring insulin, and 153 (12.2%) had diabetes of uncertain type. Most patients (1103, 88.2%) presented with the classic symptoms of diabetes. The peak time of presentation of diabetic patients requiring insulin was at age 15 to 19 years. Male manual workers and peasant farmers with diabetes not requiring insulin presented at a significantly older age and had a lower body mass index than sedentary office workers. Forty six (18.1%) of the patients requiring insulin diabetes and 111 (14.4%) not requiring insulin had first degree relative with diabetes. Twenty seven per cent of patients were underweight (body mass index less than 20 kg/m2) and 14.6% were obese (body mass index greater than 30 kg/m2). Hypertension was diagnosed in 211 (26.7%) of 791 patients not requiring insulin. Nine (3.3%) of those requiring insulin may have had the protein deficient type of diabetes related to malnutrition. The fibrocalculous variety of diabetes related to malnutrition was not observed. CONCLUSIONS Newly presenting diabetic patients in Tanzania with diabetes requiring insulin are older at presentation than those in Britain; most diabetic patients present with diabetes not requiring insulin and a smaller proportion of Tanzanian patients are obese. Most have a lower socioeconomic state than diabetic patients in Britain. There are often delays in diagnosis in Tanzania, and there is a higher incidence of death shortly after presentation.

Abstract
Twenty three patients with chronic calcific pancreatitis of the tropics in Northern India were prospectively studied. All had pancreatic calcification and ERCP changes typical of chronic pancreatitis, the most predominant being ductal dilatation which was detected in all patients by both ERCP and by ultrasonography. Pain was present in 19 (83%) patients and diabetes in 11 (48%) patients. Exocrine pancreatic dysfunction was uncommon, steatorrhoea being present in only 9% of patients. Ten of the 11 patients with diabetes required insulin for control and one case was able to be controlled by an oral antidiabetic agent. Two patients developed ketoacidosis during acute episodes of pancreatitis, 3 patients had peripheral neuropathy and one patient had visual changes. Recurrent severe pain was the reason for operation in 7 patients. All had a lateral pancreaticojejunostomy. In order to obtain an objective assessment of pain, a scoring system was developed to grade its severity according to its intensity, frequency and consequences. Six patients who preoperatively had a pain score of 15 or more (out of a maximum score of 24) attained significant relief after the surgery. We feel this scoring system may provide an easy objective assessment of pain in the subsequent follow-up of these patients.

Abstract
In magnesium deficient rats with a clinical picture of protein malnutrition, pancreatic changes typical of protein malnutrition were expected. However, in rats fed for four weeks on a low magnesium diet (protein content 25%), light and electron microscopic studies revealed that the acinar cells of the pancreas were packed with zymogen granules, suggesting a disturbance in the discharge (rather than in the production) of the pancreatic enzymes. The mitochondria and the lumina of the RER were swollen. The nuclei had an irregular outline, the chromatin was aggregated into irregular granules and the nucleolemma of the nucleolus was fibrillar. It was suggested that the disturbance in the release of pancreatic enzymes might cause a maldigestion of the dietary protein, which eventually would lead to the condition of protein malnutrition in the magnesium deficient rats. The disturbance of exocytosis in the pancreas of magnesium deficient rats might be due to the preferential use of all the available magnesium for protein (enzymes) synthesis so that there were no magnesium ions left for the energy dependent discharge of the zymogen granules.
