Introduction to Pancreatitis
What is pancreatitis?
The pancreas is a digestive gland located on the posterior abdomen wall, directly in front of the vertebrae L1 and L2. Between the right duodenum and left spleen is the pancreas. Its components are the head, neck, body, and tail. The duodenum loop surrounds the pancreatic head on the inferior vena cava and right renal vein. The pancreas tail reaches the splenic hilum. Pancreatic excretory and endocrine secretions are its main functions. Exocrine pancreatic juice (from acinar cells) goes to the duodenum through the main and auxiliary pancreatic ducts. Endocrine pancreatic juice (from the islets of Langerhans) goes to the circulation through glucagon and insulin.
Types of Pancreatitis: Acute vs. Chronic
Pancreatitis pathophysiology
Commonly, acute pancreatitis (AP) causes self-limiting pancreatic inflammation after a pancreatic injury. Pancreatitis can cause a severe multi-system inflammatory response in 25% of patients, leaving 30% to 50% dead [10]. Gallstones cause up to 40% of AP cases, while alcohol contributes 30%. Certain drugs (ACE inhibitors, sulfa-based drugs, furosemide, azathioprine, 6-mercaptopurine, and valproate), infections (such as coxsackievirus B, cytomegalovirus, and hepatitis A and E), inherited mutations in PRSS1 or cystic fibrosis, and mechanical causes (such as endoscopic retrograde cholangio) can also cause AP.
Pancreatitis pathophysiology
Chronic pancreatitis (CP) causes chronic structural damage to the pancreas, including fibrosis and ductal strictures, which eliminate exocrine and endocrine function. The prevalence of CP in the US and Europe is 0.2% to 0.6%, and 7–10 per 100,000. The main causes of CP are chronic alcohol use, which accounts for over 50% of cases, and tobacco smoking. Studies reveal an independent dose-response connection between alcohol and smoking in CP development, suggesting a synergistic impact. The fact that not all individuals with these risk variables develop AP or CP suggests further cofactors. Other causes include mutations in the CFTR, SPINK1, and PRSS1 genes. Chronic obstructive CP causes include pancreatic ductal strictures, the tumour mass effect, divisum, and Oddi dysfunction. Idiopathic and systemic immunoglobulin G4 (IgG4) illnesses are autoimmune predisposing factors. Tropical pancreatitis, which is idiopathic, is diagnosed early, has extensive ductal calculi, and progresses quickly in India, Indonesia, and Nigeria. Hyperlipidaemia and persistent hypercalcemia provide additional risks.
Understanding Pancreatitis in Children
Paediatric pancreatitis—acute recurrent and chronic—burdens children and carers. Adult and infant pancreatitis risk factors vary. Hereditary variations and congenital malformations, or gallstones, are the primary risk factors for children. Genetics and gallstones are risk factors for adults, but alcohol and tobacco use are the greatest. Diabetes, another pancreatitis risk factor, is less frequent in youngsters. Pancreatitis affects children and adults by reducing pancreatic enzyme production.
Causes of Paediatric Pancreatitis
Common Causes of Pancreatitis in Children
- Drinking alcohol can cause gallstones.
- Hypertriglyceridemia
- Drug-induced pancreatitis
- Idiopathic
- Abdominal surgery or post-op endoscopic retrograde cholangiopancreatography may be necessary.
- Ampullary stenosis, previously known as sphincter of Oddi dysfunction type I, has been identified.
- The condition is associated with type I (systemic IgG4 disease) and type II autoimmune pancreatitis
- Viral illnesses including Coxsackie, Cytomegalovirus, Echovirus, Epstein-Barr, Hepatitis A/B/C, HIV, Mumps, Rubella, and Varicella
- These infections include Campylobacter jejuni, Legionella, Leptospirosis, Mycobacterium avium, TB, and mycoplasma.
- Risk factors: smoking, trauma
- Congenital abnormalities like annular pancreas

- Haemodialysis for renal disease
- Scorpion bites have organophosphate toxicity.
- Vasculitis (SLE, Polyarteritis nodosa)
Genetic Factors Contributing to Pancreatitis
Chronic Fibrosis
Childhood hereditary pancreatic illness is most frequent in cystic fibrosis (CF). About 90% of childhood-onset pancreatic diseases depend on it. While CF affects numerous organs, increasing lung disease is the leading cause of illness and mortality. In utero, the CF pancreas begins to deteriorate. When mucus and protein obstruct the pancreas' tiny tubes that carry digesting enzymes to the gut, it scars and shrinks. 90% of CF children, typically suffering from severe malnutrition due to severe pancreatic insufficiency, receive a diagnosis at two years old. Pancreatic insufficiency necessitates the use of pancreatic enzymes with meals for 85% of CF patients. CF genes are well understood. In 1989, researchers discovered the CF gene on chromosome 7. About 70% of CF chromosomes globally have the genetic error DF508, which causes CF. More than 1000 uncommon genetic errors in the CF gene exist. Researchers are conducting numerous studies to fix the hereditary condition with gene therapy and find strategies to avoid it with medications.
SDS syndrome
SDS is the second-most prevalent hereditary cause of paediatric pancreatic failure. It is less frequent than CF and accounts for 5% of hereditary pancreatic illness. This disease also affects the liver, skeleton, and bone marrow. Children with SDS are typically small in stature and are more vulnerable to severe infections and leukaemia. Unlike CF, the SDS gene remains unknown. SDS is also on chromosome 7, according to the current study. The pancreatic issue differs from CF. Cancer cells—enzyme-producing cells—develop poorly.
Other inherited pancreatica
Hereditary pancreatic illness after CF and SDS is rare. The conditions include hereditary pancreatitis, Pearson's bone marrow syndrome, and Johanson Blizzard syndrome. Curiously, the hereditary pancreas gene is on chromosome 7. Strange coincidence!
Rarely, a kid is born without a pancreas, including its digesting (exocrine) and insulin-producing (endocrine) parts.
Environmental and Lifestyle Risk Factors
When zymogen and trypsinogen are activated too early, they damage the pancreas locally and start the inflammatory cascade, which leads to SIRS. Multiple organ dysfunction syndromes can result from systemic inflammation. Acute pancreatitis needs at least two of the following three criteria, according to the Revised Atlanta Criteria: 1) lipase or amylase levels 3 times normal; 2) pancreatitis-related physical exam; and 3) acute pancreatitis-related imaging (CT, MRI, ultrasound).
Differences Between Adult and Paediatric Pancreatitis Causes
Paediatric pancreatitis—acute recurrent and chronic—burdens children and carers. Adult and infant pancreatitis risk factors vary. Hereditary variations and congenital malformations, or gallstones, are the primary risk factors for children. Genetics and gallstones are risk factors for adults, but alcohol and tobacco use are the greatest. Diabetes, another pancreatitis risk factor, is less frequent in youngsters. Pancreatitis affects children and adults by reducing pancreatic enzyme production.

Chronic Pancreatitis in Children
Overview of Chronic Pancreatitis
Injury to interstitial mesenchymal, ductal, or acinar cells causes pancreatic fibrogenesis in CP. Pancreatic parenchymal tissue is initially damaged, leading to necrosis, apoptosis, and the release of cytokines and growth factors like TGF-α1, IL-8, PDGF, and chemokines from diverse cells. Pancreatic stellate cells (PSCs) or local fibroblasts change into myofibroblast-like cells that divide and express α-smooth muscle actin (α-SMA) to make collagen I, III, and fibronectin. This happens after the cells phagocytose and release cytokines. It is made up of myofibroblast-like cells that add new extracellular matrix (ECM) and matrix metalloproteinases (MMPs) that break down normal pericellular ECM to make room for inflammation. In addition, TGF-β1 expression in PSCs inhibits MMPs, reducing collagen breakdown and promoting fibrogenesis. Consuming ethanol may cause resident fibroblasts to bypass this inflammatory process, induce lithogenic proteins, increase the viscosity of pancreatic secretion, and form protein plugs that block ducts, damage, and atrophy acinar cells. After each pancreatic injury, fibrogenesis and atrophy worsen pancreatic function. Recurrent pancreatitis following AP and CP is linked to alcohol misuse and tobacco smoking.
How Chronic Pancreatitis Develops in Children
Acute recurrent pancreatitis (ARP) is two bouts of acute pancreatitis (AP), whereas chronic pancreatitis (CP) is persisting pancreatic inflammation. Genetic mutations, autoimmune pancreatitis, congenital pancreatic abnormalities, and other circumstances can cause these conditions in children. The illness spectrum includes acute recurrent pancreatitis, which often precedes CP. Early ARP-to-CP transition is associated with genetics. Clinical observations, metabolic testing, and imaging investigations diagnose CP and AP. Exocrine pancreatic dysfunction helps diagnose CP. Step-up CP therapy is becoming more common. Surgical treatment follows endoscopic pancreatic sphincterotomy and stenting if endoscopic therapy fails or is impossible. We frequently give non-opioid (ibuprofen/naproxen) and opioid (oxycodone) analgesia to paediatric patients with AP or CP, while pancreatic enzyme replacement treatment may help with stomach discomfort, steatorrhea, and malnutrition.
Impact of Chronic Pancreatitis on a Child’s Health and Growth
CP is rare in children but can cause serious issues that might impede quality of life and growth. Consequences include pain, pancreatogenic diabetes, exocrine pancreatic insufficiency, and malnutrition. According to their doctors, CP-afflicted children consume opioids in unknown quantities. Few studies address CP pain in children, which limits pain relief. 25% of CP children have exocrine pancreatic insufficiency; 6% have pancreatogenic diabetes. These problems require routine testing for early detection. Finally, CP children often have moderate malnutrition, fat-soluble vitamin insufficiency, and inadequate bone mineral density. These kids need regular monitoring to be healthy and develop normally.
Diagnosing Pancreatitis in Children: Blood tests are ordered to identify acute pancreatitis. An abdominal ultrasound can detect gallstones, while a CAT scan can detect pancreatic inflammation or damage. CAT scans uncover pseudocysts.
Challenges in Diagnosing Paediatric Pancreatitis
When pancreatic enzymes (acini function) and/or sodium bicarbonate (ductal function) are secreted inefficiently, nutrients are not absorbed properly in the gastrointestinal (GI) tract. When 90% of pancreatic tissue sustains damage and enzyme levels fall to 5–10% of normal physiological levels, it leads to steatorrhea. EPI primarily affects lipase, leading to a reduction in the absorption of fat and fat-soluble vitamins. The pancreas digests all macronutrients. Rareness and non-specific GI symptoms make early EPI diagnosis problematic.
Treatment Options for Paediatric Pancreatitis
Acute Pancreatitis Treatment in Children
Surgery treats haemorrhage, necrosis, ductal fistulae, and pseudocysts. Successful pancreatic pseudocyst surgery. Lower recurrence and death rates. Percutaneous and endoscopic drainage have higher recurrence rates than internal drainage. We should study transendoscopic and percutaneous drainage in children to find the best treatment for pancreatic pseudocysts. Current research has mostly focused on adults.
Chronic Pancreatitis Treatment Approaches
Chronic pancreatitis causes inflammation, fibrosis, and scarring and is irreversible. Chronic pain results from exocrine and endocrine dysfunction. Drinking is the biggest risk factor in adults; however, the cause is multifaceted. Between 35 and 55 is the usual diagnostic age. CT is ideal for diagnosing chronic pancreatitis. Computed tomography may be inconclusive early in the illness; thus, magnetic resonance imaging, cholangiopancreatography, or endoscopic ultrasonography with or without biopsy may be employed. We advise patients to quit alcohol and tobacco, and to eat modest, frequent, low-fat meals. Half of patients need surgery, even though opioids and antidepressants relieve pain best. Therapeutic endoscopy is used to treat strictures, stones, and pseudocysts. Large duct disease (dilation of 7 mm or greater) requires decompressive surgery, such as lateral pancreaticojejunostomy. Whipple surgery is the recommended treatment for small duct disease or pancreatic head enlargement. Prolonged pancreatitis, especially inherited, increases pancreatic cancer risk. Clinicians should advise patients on this elevated risk and check weight loss or jaundice for neoplasia, even if screening may not improve outcomes.
Long-Term Management of Chronic Pancreatitis in Children
The importance of monitoring and regular check-ups
Monitoring the BMI regularly with a proper understanding of patients' diet is of utmost importance. While any of the symptoms of the post-treatment period would aggravate the patient’s condition.
Managing pain and digestive health.
During the acute pain, the pain relievers are to be suggested to be used under proper guidance. Besides, the metabolism and the whole intestine mechanism have to be good, so the digestive functionality works better.
Nutritional Support and Diet Recommendations
Enteral and parenteral nutrition assistance has advanced greatly in the previous 30 years. Both oral nutrition and tube-fed nutrition are forms of internal nutrition. By peripheral or central venous access, parenteral nutrition delivers nutrients to the circulation. Central parenteral nutrition encompasses all aspects of parenteral nutrition, whereas peripheral parenteral nutrition focuses on specific areas. Many patients have benefited from enteral and parenteral procedures, equipment, nutritional formulations, and gastrointestinal and venous access devices in obtaining adequate nourishment.
Preventing flare-ups and reducing pancreatic strain
Doctors advocate reducing pancreatitis-causing meals. When chronic pancreatitis occurs, the pancreas cannot create enough enzymes to breakdown fats, carbs, and protein. After consuming high-fat and carb meals, your body may not absorb enough nutrients and cause stomach pain.
Complications Associated with Paediatric PancreatitisPotential Health Complications for Children with Chronic Pancreatitis
25% of CP children have exocrine pancreatic insufficiency; 6% have pancreatogenic diabetes. These problems require routine testing for early detection. Finally, CP children often have moderate malnutrition, fat-soluble vitamin insufficiency, and inadequate bone mineral density. These kids need regular monitoring to be healthy and develop normally.
How can pancreatitis affect other organs?
Recurring pancreatitis. Recurrence depends on the aetiology and treatment. Problems with acute pancreatitis include:
- Renal failure suddenly
- Lung injury (ARDS)
- Abdominal fluid increases.
- Pancreas abscesses
- Failed heart
Risk of diabetes and other related conditions
Debilitating pain, diabetes, pancreatic pseudocysts, and pancreatic cancer are the leading causes of morbidity and mortality from chronic pancreatitis. Pain is common at diagnosis, although diabetes develops over five years. Most pancreatic pseudocysts are asymptomatic, but 25% to 30% might cause significant problems. Rerupture, infection, bleeding, and blockage can result from pseudocysts. Frequent acute pancreatitis can induce abscesses, necrosis, sepsis, and multi-organ failure. One-quarter (23.4%) of chronic pancreatitis patients have osteoporosis, and two-thirds (65%) had one or both. Chronic pancreatitis, especially long-term alcohol use or hereditary pancreatitis, puts individuals at risk of pancreatic cancer.
Conclusion
It is crucial to monitor these diseases, and if someone notices any symptoms or findings, they should consult a specialist or visit Ovum Hospital for more effective medical advice and treatment.
FAQs
1: What causes childhood chronic pancreatitis?
Repeated acute pancreatitis can cause chronicity. Sometimes genetics has a role. However, occasionally the cause is unknown.
2: Why do certain foods seem to be fine and others problematic?
This phenomenon affects many people, although its cause is unknown. To rule out an enzyme deficiency, use pancreatic enzymatic supplements daily.
3: Are there additional vitamins or supplements?
Patients with chronic pancreatitis need routine evaluations for nutritional deficits to prevent chronic malabsorption. An annual blood test should guide vitamin therapy. Blood tests may guide the administration of multivitamins, calcium, iron, folate, vitamin E, vitamin A, vitamin D, and vitamin B12.
