التهاب الكبد ج

أسباب

The hepatitis C virus is spread through contact with the blood of an infected person.

A woman with hepatitis can pass the virus on to her baby during birth. The hepatitis C virus is not spread through food or water.

عوامل الخطر

Factors that increase your chance of this infection:

• Injecting illicit drugs, especially with shared needles
• Receiving a blood transfusion before 1992—this risk is very low in the United States.
• Receiving blood clotting products before 1987
• Receiving an HCV-infected organ transplant
• Long-term kidney dialysis treatment
• Sharing toothbrushes, razors, nail clippers, or other personal hygiene items that have HCV-infected blood on them
• Being accidentally stuck by an HCV-infected needle—a concern for healthcare workers
• Frequent contact with HCV-infected people—a concern for healthcare workers
• Tattooing
• Body piercing
• Having sex with partners who have hepatitis C or other sexually transmitted diseases—this is most common in men who have sex with men.

الأعراض

Eighty percent of people with hepatitis C have no symptoms. Over time, the disease can cause serious liver damage.

قد تشمل الأعراض ما يلي:

• تعب
• فقدان الشهية
• Jaundice (yellowing of the eyes and skin)
• Darker colored urine
• Loose, light, or chalky colored stools
• ألم في البطن
• Aches and pains
• مثير للحكة
• خلايا النحل
• الم المفاصل
• Cigarette smokers may suddenly dislike the taste of cigarettes
• الغثيان
• القيء

Chronic hepatitis C may cause some of the above symptoms, as well as:

• ضعف
• التعب الشديد
• فقدان الشهية

Serious complications of hepatitis C include:

• Chronic infection that will lead to cirrhosis (scarring) and progressive liver failure
• Increased risk of liver cancer

التشخيص

Your doctor will ask about your symptoms and medical history. A physical exam will be done. You will also discuss your risk factors.

قد تشمل الاختبارات ما يلي:

• Blood tests—to look for hepatitis C antibodies or genetic material from the virus (antibodies are proteins that your body has made to fight the hepatitis C virus)
• Liver function studies— to initially determine and follow how well your liver is functioning
• Ultrasound of the liver—to assess liver damage
• Liver biopsy —removal of a sample of liver tissue to be examined

العلاج

Hepatitis C is usually treated with combined therapy, consisting of:

• Interferon—given by injection
• Ribavirin —given orally
• Protease inhibitor

These medicines can cause difficult side effects. They also have limited success rates.

In unsuccessful cases, chronic hepatitis C can cause cirrhosis and serious liver damage. A liver transplant may be needed, although it does not typically cure hepatitis C.

If you are diagnosed with hepatitis C, follow your doctor’s instructions .
