4. Hepatitis C - Clinical Presentation

Quick info:

Hepatitis C cannot be diagnosed through clinical features alone, and patients are often asymptomatic. People with chronic hepatitis C may be identified:

  • following screening tests for people at high risk (common)
  • through follow up, after a diagnosis of acute hepatitis C
  • as a result of abnormal liver function tests (LFTs)

Acute hepatitis C infection:

  • usually asymptomatic and has a clinically mild course
  • occurs after an incubation period of 6-9 weeks
  • only 25–35% of people experience symptoms (rarely severe), e.g.:
  • mild flu-like illness
  • nausea and vomiting
  • pain in the right upper quadrant
  • jaundice and dark coloured urine (rare)
  • rarely presents with fulminant hepatic failure

Chronic hepatitis C infection:
Symptoms tend to be non-specific, e.g.:

  • mild to severe fatigue
  • muscle aches
  • nausea
  • depression
  • anxiety
  • pain or discomfort in the liver
  • poor memory or concentration

Signs of liver decompensation may be present in those with advanced liver disease, e.g.:

  • jaundice
  • ascites
  • hepatic encephalopathy
  • variceal (often oesophageal) bleeding
  • often remains asymptomatic until liver disease is advanced

Ask about:

  • intravenous (IV) drug use
  • blood transfusions or products recipient prior to September 1991
  • high-risk sexual behaviour
  • healthcare intervention in an endemic area, e.g., dialysis

Birth in high-endemicity region, e.g.:

  • Pakistan
  • Egypt
  • Romania
  • Easter European States
  • tattoos or piercings
  • occupational risk of exposure

Consider and record risk factors related to poor prognosis:

  • excessive alcohol consumption (past and present) - strongly associated with:
  • a poor prognosis
  • progression to severe liver complications

Weight - a body mass index (BMI) greater than 25 kg/m2 is associated with an increased risk of:

  • hepatic steatosis
  • disease progression
  • smoking - independent risk factor for hepatic inflammation
  • age at infection - infection at an older age causes a more rapidly progressing disease
  • current age - older age is a predictor of increased progression, independent of length of infection
  • male gender - men are more likely to progress to cirrhosis than women


  • progression of chronic disease may be less rapid in black people
  • Asian people may experience more rapid progression to cirrhosis
  • co-infection with the following (causes more rapid disease progression to serious illness):
  • HIV
  • hepatitis B

Examination for any stigmata of chronic liver disease, e.g.:

  • organomegaly
  • signs of decompensated liver disease

Before proceeding with testing, inform the person about the benefits of being tested and high success rate of oral treatment greater than 95%.

5.  Screening for Hepatitis C in high-risk groups

Quick info:
Screen the following people for hepatitis C using a hepatitis C virus (HCV) antibody test:

  • injecting drug users or those who have injected drugs in the past
  • those who are blood or organ recipients in the UK and who have received:
  • whole blood or organs prior to 1992
  • blood products prior to 1986
  • babies/children born to women found/known to be infected with hepatitis C
  • healthcare workers who have been accidentally exposed to blood where there is a risk of hepatitis C, e.g., needle stick injuries
  • people who have:
  • unexplained abnormal liver function tests (LFTs) or who present with overt liver failure

Received the following procedures in countries where hepatitis C is common and infection control may be poor (including people who have received blood transfusion products that have not been screened for hepatitis C):

  • medical
  • cosmetic surgery over sea
  • dental treatment
  • street shaving
  • barbers
  • any other invasive treatment
  • had tattoos or body piercing where unsterilized equipment may have been used - especially consider tattooing and piercing received in the UK before the mid-1980s or in other countries at any time
  • tested positive for:
  • hepatitis B see 'Hepatitis B' care map
  • HIV

Consider screening the following people, particularly if they have unexplained symptoms:

  • people who:
  • have, or are currently, snorting, or smoking drugs, e.g., cocaine, particularly if they have shared straws or pipes

Were born in countries where hepatitis C is endemic, e.g.:

  • Pakistan
  • Egypt
  • Middle East
  • Eastern Europe (especially Poland, Romania, and Lithuania)
  • regular sexual partners of people who are known to have chronic hepatitis C

The following people will usually be routinely screened outside of primary care:

  • who intend to donate blood or organs
  • with renal failure or who are on dialysis
  • healthcare workers
  • Anyone who has been in prison (or YOI) and/or shared injecting paraphernalia in prison
  • Commercial sex workers and other high risk sexual behaviour
  • Close contacts of someone known to be chronically infected with hepatitis C
  • Prior to testing, inform the person about the benefits of being tested.

6.  Investigation Abnormal LFTs

Quick info:
Anyone with a raised ALT should be considered for a Hepatitis C test - See 'Abnormal ALT pathway' for more details.

7.  Hepatitis C Screen

Quick info:
Screening test is the Hepatitis C Antibody.
If this is negative the person has not been infected with Hepatitis C.
Check not at risk of acquiring infection e.g., drug use or unsafe MSM - if so consider regular testing.

8a. HBsAg Negative HBcAb Negative

Quick info:
No further action

9a. Hepatitis C Surface Antigen (HBsAg) Positive

Quick info:
A positive test indicates exposure. To confirm on-going active infection a PCR test for viral RNA is needed.

B) For first tests from primary care the lab will automatically do this they will also request a confirmatory sample.

C) And HCV PCR -ve (HBV, HIV & LFT Negative)
Quick info:
Referral not required
This means previous infection - now cleared.
These needs confirming at three months.
Check the patient is not at risk of acquiring infection e.g., drug using or MSM population - if so consider regular testing.
This would need to be HCV PCR as the antibody is already positive.

D) And HCV PCR -ve (HBV, HIV negative but LFTs Abnormal)
Quick info:
Previous Hep C now cleared
LFTs abnormal so proceed to investigations outlined in the abnormal LFT pathway.

  • Harm Reduce Advise & Counselling

Quick info:

  • provide the person with information about hepatitis C, and advice on how to prevent transmission of the infection

Advise patients:

  • to reduce alcohol consumption, advise the person to avoid drinking alcohol

Risks of transmission:

  • use barrier intercourse if hepatitis B virus (HBV) status/vaccination of patient unclear
  • do not share toothbrush, razors, hair clippers
  • cover open cuts, scratches
  • clear blood spills with bleach, disinfectant
  • do not donate blood or semen


  • children should not be excluded from school or out of school activities
  • food utensils can be shared safely
  • HCV PCR Positive Refer Hepatology (Viral Hepatitis Clinic)

Quick info:
Viral Hepatitis Clinic appears on Choose and Book

10. Refer Hepatology (Viral Hepatitis Clinic)

Quick info:

  • If patients have had blood tests or dried blood testing or scans, outside Leeds, please ensure the referral includes these results.
  • If also HIV positive, then will need referral to both Hepatology and HIV services
  • If also Hepatitis B positive, then a single referral to Hepatology will suffice.

11. Red Flag

Quick info:

  • Clinically symptomatic acute hepatitis C is uncommon.
  • Suspect it in active intravenous drug users, recent tattoos etc presenting with jaundice or symptomatic with high ALT (> 300).
  • In this situation the antibody may be negative so request hepatitis C PCR directly and make it clear on the request that acute hepatitis C is suspected. Refer these patients urgently to viral hepatitis clinic. If the patient is very unwell admit through normal procedures at GP's discretion.
