Chronic hepatitis is a condition characterized by inflammation of the liver parenchyma lasting for more than six months. It has variable clinical features ranging from no symptoms to fulminant liver failure irrespective of the cause of chronic hepatitis. Several viruses (hepatitis B, C, D, and E ) are known to cause chronic active hepatitis with progression to cirrhosis [1] [2] as well as hepatocellular carcinoma. Chronic hepatitis develops over several years [1]. Other causes of chronic hepatitis include autoimmune hepatitis, drugs like isoniazid, nitrofurantoin and methyldopa (long-standing use), alcohol, non-alcoholic steatohepatitis, deficiency of alpha -1-antitrypsin, Wilson's disease, and hemochromatosis.

Non-specific symptoms of anorexia, easy fatigability, malaise with low-grade fever and upper quadrant abdominal discomfort may be seen in cases of chronic hepatitis although, many patients are asymptomatic and diagnosed incidentally due to elevated liver enzymes. In advanced stages of chronic hepatitis, features of cirrhosis like hepatosplenomegaly, palmar erythema, parotid enlargement, spider nevi, gynecomastia and even ascites, portal hypertension and hepatic encephalopathy may be present. Cholestasis can produce symptoms of jaundice, acholic stools, pruritus, and steatorrhoea. In women with autoimmune chronic hepatitis, features of other organ involvement such as arthralgias, menstrual irregularities, ulcerative colitis, thyroiditis, pulmonary fibrosis, nephritis and hemolytic anemia are seen. Extra-hepatic manifestation like lichen planus, vasculitis, porphyria cutanea tarda, glomerulonephritis, cryoglobulinemia and even lymphomas are noted in chronic hepatitis secondary to hepatitis C while ataxia with other neurological manifestation has been reported in chronic hepatitis E [3] [4].

The workup in all cases should begin with a detailed history and physical examination. As the etiology of chronic hepatitis can be variable like congenital alpha-1-antitrypsin deficiency, viral, autoimmune or long-standing usage of drugs and alcohol, the workup should specifically note previous history of hepatitis, high risk behavior (drug /alcohol abuse, multiple sexual partners), tattoos /piercings, history of incarceration, blood/ blood product transfusion, surgery, autoimmune diseases etc). Needle tracks, features of icterus, cirrhosis, and cholestasis should be looked for during physical examination.

Routine laboratory tests like complete blood count, urinalysis, stool analysis, liver enzymes, serum proteins and, coagulation profile are obtained. If hepatitis is confirmed on laboratory tests then specific tests to detect etiology of the chronic hepatitis are performed. These include viral serology, autoantibodies, alpha-1-antitrypsin levels, immunoglobulins, ceruloplasmin levels (in children to rule out Wilson's disease). Serum iron, ferritin, and total iron-binding capacity levels can help detect hemochromatosis as the cause of chronic hepatitis.

If an asymptomatic patient is detected with elevated liver enzymes and if they were born between 1945 and 1965, they should be evaluated for hepatitis C. Cryoglobulin and rheumatoid factor levels are assessed in patients with chronic hepatitis secondary to hepatitis C.

Liver biopsy is the gold standard for the diagnosis of chronic hepatitis and provides information about the extent of cellular necrosis, parenchymal fibrosis and inflammation [5] [6]. Histopathology can also detect steatohepatitis and iron deposition and helps to plan further disease management and prognosis [7]. Fibroscan, an ultrasound-based procedure can detect liver fibrosis in advanced cases while blood tests like FIBROSpect II, HepaScore, and HCV FIBROSURE are used to detect mild and severe stages of liver fibrosis.

The treatment of chronic hepatitis depends on its cause. For viral hepatitis, antiviral medications can help control the infection. In cases of autoimmune hepatitis, corticosteroids or other immunosuppressive drugs may be prescribed. Lifestyle changes, such as avoiding alcohol and maintaining a healthy diet, are essential for all patients. In severe cases, where liver damage is extensive, a liver transplant may be considered.

The prognosis for chronic hepatitis varies based on the cause and severity of the disease. With appropriate treatment, many patients can manage their symptoms and prevent further liver damage. However, if left untreated, chronic hepatitis can progress to cirrhosis or liver cancer, significantly impacting life expectancy and quality of life.

Chronic hepatitis can result from several causes. The most common are viral infections, particularly hepatitis B and C. Autoimmune hepatitis occurs when the body's immune system mistakenly attacks liver cells. Long-term use of certain medications, excessive alcohol consumption, and exposure to toxins can also lead to chronic hepatitis.

Chronic hepatitis is a global health issue, affecting millions of people worldwide. Hepatitis B and C are the most prevalent causes, with higher rates in regions like Asia and Africa. The incidence of chronic hepatitis varies based on factors such as age, gender, and lifestyle, with certain populations at higher risk due to genetic or environmental factors.

In chronic hepatitis, persistent inflammation leads to liver cell damage and death. Over time, this can cause fibrosis, where scar tissue replaces healthy liver tissue, impairing liver function. If fibrosis progresses, it can lead to cirrhosis, characterized by severe scarring and loss of liver function. The liver's ability to regenerate is compromised, leading to potential liver failure.

Preventing chronic hepatitis involves addressing its underlying causes. Vaccination is available for hepatitis B, significantly reducing the risk of infection. Safe practices, such as using clean needles and practicing safe sex, can prevent viral transmission. Limiting alcohol intake and avoiding unnecessary medications can also help protect the liver.

Chronic hepatitis is a prolonged inflammation of the liver with various causes, including viral infections and autoimmune disorders. It can lead to significant liver damage if not managed properly. Diagnosis involves a combination of clinical evaluation and tests, while treatment focuses on addressing the underlying cause and preventing further damage. With appropriate care, many patients can lead healthy lives.

If you suspect you have chronic hepatitis, it's important to understand the condition and its implications. Chronic hepatitis means your liver is inflamed for a long time, which can lead to serious health issues if not treated. Symptoms can vary, and some people may not feel sick at all. Diagnosis usually involves blood tests and sometimes a liver biopsy. Treatment depends on the cause but often includes medication and lifestyle changes. Preventive measures, like vaccination and safe practices, are crucial in reducing the risk of chronic hepatitis.
