What is Primary Sclerosing Cholangitis (PSC) — Comprehensive Review?

PSC is a chronic, idiopathic, progressive cholestatic disorder featuring inflammation, fibrosis, and obliteration of intrahepatic and extrahepatic bile ducts in a multifocal pattern.

Approximately 60–80% of PSC patients have concurrent inflammatory bowel disease (most commonly ulcerative colitis with pancolonic, often mild, distribution).

Magnetic resonance cholangiopancreatography (MRCP) is the diagnostic modality of choice, revealing characteristic multifocal strictures with a beaded appearance; small-duct PSC requires liver biopsy for diagnosis.

PSC carries a 10–15% lifetime risk of cholangiocarcinoma and elevated risks of gallbladder cancer and PSC-IBD–associated colorectal carcinoma.

Symptoms

Asymptomatic elevation of alkaline phosphatase and gamma-glutamyl transferase on routine screening
Fatigue, debilitating pruritus (often nocturnal), and right upper quadrant discomfort
Episodic jaundice, dark urine, and pale stools indicating dominant stricture or cholangitis
Fever, chills, and rigors raising concern for acute bacterial cholangitis
Weight loss, steatorrhea, and fat-soluble vitamin (A, D, E, K) deficiencies
Decompensation manifestations: ascites, variceal bleeding, hepatic encephalopathy, hepatopulmonary syndrome

Risk Factors

Inflammatory bowel disease, particularly ulcerative colitis with pancolitis
Male predominance (male-to-female ratio approximately 2:1)
Peak diagnosis age 30–50 years
First-degree family history of PSC, autoimmune liver disease, or IBD
HLA-B8, HLA-DR3, HLA-DRB1*03:01 genetic haplotypes
Northern European ancestry

When to See a Doctor?

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

  • Persistent unexplained elevation of alkaline phosphatase, especially in patients with IBD
  • New-onset jaundice, fever, or severe right upper quadrant pain suggesting acute cholangitis
  • Newly diagnosed IBD patients for baseline hepatobiliary screening and surveillance planning
  • Worsening pruritus, ascites, or hepatic decompensation in known PSC

Treatment Methods

01
No proven disease-modifying therapy; ursodeoxycholic acid use remains controversial — moderate doses 15–20 mg/kg/day may improve biochemistry without proven survival benefit (avoid high-dose >28 mg/kg/day)
02
Endoscopic management of dominant strictures: ERCP with balloon dilation and selective stenting; brush cytology and FISH analysis for cholangiocarcinoma surveillance
03
Antibiotic prophylaxis pre-ERCP and prompt empiric therapy for bacterial cholangitis (ciprofloxacin or ceftriaxone, adjusted to culture)
04
Cancer surveillance: annual MRI/MRCP with CA 19-9; annual colonoscopy with biopsies in PSC-IBD; annual abdominal ultrasound for gallbladder polyps
05
Symptomatic care for pruritus (cholestyramine, rifampin, naltrexone, sertraline), fat-soluble vitamin supplementation, and bone density monitoring with calcium/vitamin D
06
Liver transplantation for end-stage liver disease, intractable pruritus, recurrent bacterial cholangitis, or early hilar cholangiocarcinoma (Mayo Clinic protocol with neoadjuvant chemoradiation)

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.
