What is Chronic Parenteral Nutrition (Long-Term Home TPN)?

Chronic parenteral nutrition delivers all nutritional needs intravenously through a tunneled central venous catheter or implanted port for months to years.

It is indicated when intestinal failure precludes adequate enteral absorption — short bowel syndrome, motility disorders, refractory inflammatory bowel disease or radiation enteritis.

The formulation includes amino acids, dextrose, lipid emulsions, multivitamins, trace elements, electrolytes and fluid tailored to individual needs.

Most patients receive cyclic infusions over 10–14 hours overnight, allowing daytime independence.

Long-term complications include catheter-related bloodstream infections, central venous thrombosis, intestinal failure-associated liver disease and metabolic bone disease.

Symptoms

Persistent weight loss and progressive malnutrition despite oral or enteral feeding
Inability to absorb sufficient calories, protein or micronutrients due to intestinal disease
Severe diarrhea with high-output stomas or fistulas causing dehydration
Recurrent dehydration episodes requiring hospitalization for IV fluids
Vitamin and mineral deficiencies (B12, iron, magnesium, calcium, fat-soluble vitamins) unresponsive to oral supplementation
Failure to thrive with sarcopenia, fatigue and impaired immune function

Risk Factors

Short bowel syndrome after extensive small bowel resection (less than 100–200 cm)
Chronic intestinal pseudo-obstruction or severe motility disorder
Refractory Crohn disease with extensive bowel involvement or short bowel after multiple surgeries
Radiation enteritis with severe malabsorption
Mesenteric ischemia with extensive bowel infarction
Congenital intestinal disorders (microvillous inclusion disease, tufting enteropathy)
Severe high-output enterocutaneous fistulas

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Persistent weight loss despite optimized oral or enteral nutrition
  • Recurrent severe dehydration requiring hospitalization
  • Symptoms of catheter sepsis: fever, chills, hypotension or rigors during or shortly after infusion
  • Catheter site redness, swelling, drainage or pain
  • Jaundice, abdominal distension or rising liver enzymes suggesting liver injury
  • Refractory bone pain or fragility fractures
  • Sudden cessation of infusion with severe hypoglycemia

Treatment Methods

01
Refer to specialized intestinal failure center for evaluation, formulation and ongoing care
02
Place tunneled central venous catheter (Hickman, Broviac) or subcutaneous port using sterile technique
03
Tailor macronutrient and micronutrient prescription to individual needs based on indirect calorimetry, fluid balance and laboratory monitoring
04
Implement strict catheter care protocol with chlorhexidine site care, taurolidine or ethanol locks to prevent infection
05
Use mixed-oil lipid emulsions (SMOF) instead of soy-based emulsions to reduce intestinal failure-associated liver disease
06
Monitor liver function, vitamins, trace elements and bone density at regular intervals (every 3–6 months)
07
Consider teduglutide (GLP-2 analog) to enhance intestinal absorption and reduce parenteral support
08
Evaluate for intestinal transplantation in patients with life-threatening complications of long-term parenteral nutrition

Anaemia

Dahiliye (İç Hastalıkları)

Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.

Iron Deficiency Anaemia

Dahiliye (İç Hastalıkları)

Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.

Vitamin B12 Deficiency

Dahiliye (İç Hastalıkları)

Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.

Hypertension (High Blood Pressure) Management

Dahiliye (İç Hastalıkları)

Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.

Chronic Kidney Disease

Dahiliye (İç Hastalıkları)

Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.

Hepatitis B (HBV)

Dahiliye (İç Hastalıkları)

Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.

Hepatitis C (HCV)

Dahiliye (İç Hastalıkları)

Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.

Fatty Liver Disease

Dahiliye (İç Hastalıkları)

Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
