Alcohol-induced chronic pancreatitis is associated with bone loss, but bone histomorphometric data describing the mechanism of cortical (Ct) and trabecular (Tb) bone loss are scarce. In this case-control study, we investigated 13 black male patients aged 41.2 +/- 8.9 years with alcohol-induced chronic pancreatitis by routine iliac crest cortical and trabecular histomorphometry and by biochemistry relevant to bone, liver function, and iron overload. Patients showed lower values for Ct thickness (P = 0.018), endocortical (Ec) wall thickness (P = 0.0002), Tb bone volume (0.019), Tb thickness (0.001), Tb wall thickness (P < 0.0001), Ec osteoid thickness (P = 0.001), Ec mineral apposition rate (P = 0.011), and Ec bone formation rate (P = 0.035). Ec eroded surface (P = 0.004) was elevated compared to controls. Tb osteoid thickness (P = 0.14) and Tb mineral apposition rate (P = 0.195) tended to be lower than in controls. Levels of 25-hydroxyvitamin D (P < 0.005), serum magnesium (P = 0.02), and ascorbic acid (P = 0.049) were lower and urine calcium/creatinine ratios higher than in controls. Alkaline phosphatase and gamma-glutamyl transpeptidase (GGT) were negatively correlated but iron markers were positively correlated with bone structural and formation variables. The histomorphometric data were found to be consistent with alcohol bone disease. Osteomalacia was not a feature. Secondary pathogenetic factors were liver disease, hypovitaminosis D and C, diabetes mellitus, and possibly chronic pancreatitis.

Chronic pancreatitis is a disease that leads to irreversible changes in the pancreatic morphology and function. The loss of function can lead to diabetes mellitus and exocrine pancreatic insufficiency. The inflammation and fibrosis can also lead to other complications including a chronic abdominal pain syndrome, metabolic bone disease, and pancretic cancer. This article reviews our current understanding of the mechanisms and management of these complications of chronic pancreatitis.

Patients with chronic pancreatitis (CP) may have a higher prevalence of osteoporosis than the general population thereby increasing the risk of bone fracture. The pathophysiology of bone disease in CP is multifactorial. Their risk factors for secondary osteoporosis include increasing age, low body mass index from sitophobia, maldigestion due to exocrine pancreatic insufficiency (EPI) with resulting low vitamin D, as well as smoking and alcohol abuse. An obvious association of bone disease with CP is from EPI with maldigestion of fat-soluble vitamins including vitamin-D, which has a significant role in the process of bone formation. Vitamin-D deficiency may be higher in CP patients vs controls, and it is especially so in CP patients with EPI. Screening for CP-associated osteopathy, including osteopenia and osteoporosis, should be initiated early in the course of CP, as the overall prevalence of bone disease is approximately two-thirds of CP patients. Our initial approach in the treatment of osteoporosis should include correction of maldigestion resulting from EPI with use of pancreatic enzyme replacement therapy (PERT). PERT, which is the treatment for EPI is associated with improvement in Dual energy X-ray absorptiometry (DXA) values and vitamin-D levels compared to those who are not treated. This should improve, in addition to body mass index, vitamin-D deficiency and calcium absorption as well as improve overall nutritional status. Osteopathy is common in CP patients, has significant associated morbidity, should be screened for regularly, and corrected with fat soluble vitamin supplementation and PERT to prevent clinical sequelae. In this article, we review the epidemiology, pathophysiology, and treatment of bone disease in patients with CP.

Chronic pancreatitis is characterized by progressive, irreversible morphologic and functional changes that are most commonly attributed to environmental insults, particularly when there is a genetic or anatomic predisposition. Heavy alcohol use and cigarette smoking are the most common environmental risk factors, but both may be absent. Antecedent episodes of acute pancreatitis occur in about half of patients. Abdominal pain is the most common symptom and requires a tailored approach depending on the anatomic changes in the pancreas. Other clinical manifestations include diabetes mellitus, exocrine pancreatic insufficiency, metabolic bone disease, pancreatic cancer, and anatomic complications. Current disease management is centered on risk factor reduction and screening for and treating disease complications. There are no current therapies to delay or retard disease progression, but there are ongoing efforts to more fully understand the natural history of chronic pancreatitis and underlying mechanisms of disease. These studies are expected to provide insights that will transform our approach to disease management and provide increased hope to patients.

Bone disease (osteopenia or osteoporosis) is a highly prevalent condition in society and presents a tremendous, preventable public health burden. Screening procedures, such as, dual-energy X-ray absorptiometry scans, have allowed early identification and intervention to improve bone health, and reduce the risk of osteoporotic fractures, which carry significant morbidity and mortality. The association of bone disease has been recognized in several diseases of the gastrointestinal tract, resulting in established guidelines for screening in patients with malabsorptive disorders such as inflammatory bowel disease and celiac disease. Increasingly, the risk of bone disease has been recognized in patients with chronic pancreatitis (CP), who share similar risk factors as patients with other high gastrointestinal disorders. As a result, there have been a number of studies examining the prevalence and risks of bone disease and fractures in patients with CP. This review aims to summarize the recent literature and current recommendations related to bone disease in CP.
