Whats The Difference Between Acute And Chronic Hepatitis C
Hepatitis C is a contagious disease caused by HCV, which is spread through contact with blood and bodily fluids that contain HCV. This disease damages your liver. There are two types of hepatitis C infection: acute and chronic.
Acute hepatitis C is a short-term viral infection. People with acute hepatitis C carry the infection for a small window of time, often just several months . Most people with the acute form of hepatitis C will experience illness and mild symptoms such as fatigue and vomiting within the first six months after exposure. In many cases, the disease causes no symptoms at all.
Acute hepatitis C may improve or resolve without treatment. It leads to chronic infection in 75 to 85 percent of cases. The chronic form may cause long-term problems in your liver, including liver damage and liver cancer.
HCV is spread through direct contact with blood or certain bodily fluids that contain HCV. Its safe to engage in the following activities without worry of transmission:
If your doctor suspects that you have hepatitis C, they will draw blood to check for HCV antibodies. Antibodies are substances your body produces when its fighting an infection. If you have them, your doctor may order a second test to confirm that the virus is still present.

Severe Morbidity And Mortality
For patients with a principal diagnosis of acute hepatitis B, 2,408 hospital bed days were recorded. The median length of stay was three days, with longer stays for adults aged 60 years and over . There were 22 deaths from acute hepatitis B recorded in the two years 2003 to 2004, 17 in males and five in females. All of the deaths occurred in those aged 25 years and over, and nearly two thirds were aged over 60 years, in whom nine of the fourteen were males. In 2003, there were twice as many deaths as in 2004 . There were four cases of hepatic coma recorded among hospitalisations with a principal diagnosis of acute hepatitis B, with none of these cases recorded as having delta co-infection . There were three deaths reported to NNDSS in notified cases between 2003 and 2005.

How Can I Be Sure That The Patient Has Hepatitis B Virus Infection
HBV infection presents with nonspecific features. Infection with HBV has a wide spectrum of manifestations, including subclinical hepatitis, anicteric hepatitis, icteric hepatitis, and fulminant hepatitis during the acute phase and the asymptomatic carrier state. HBV infection includes chronic hepatitis, cirrhosis, and hepatocellular carcinoma during the chronic phase.
Approximately 70% of patients with acute HBV infection have subclinical hepatitis or anicteric hepatitis, whereas 30% become icteric. Acute liver failure develops in approximately 0.1% to 0.5% of patients. The incubation period lasts 1 to 4 months. A serum sickness-like syndrome may develop during the prodromal period. This is followed by constitutional symptoms such as low-grade fever, malaise, anorexia, nausea and vomiting, and right upper quadrant or midepigastric pain. Jaundice usually appears as the constitutional symptoms begin to subside. Clinical symptoms and jaundice generally disappear after 1 to 3 months, but some patients may have prolonged fatigue, even after normalization of aminotransferase levels.

How Is Hepatitis D Diagnosed
Hepatitis D is diagnosed by an ELISA that detects the presence of antibody to hepatitis D in serum or plasma. The presence of the antibody in serum correlates with ongoing hepatitis D replication in the liver. Detection of hepatitis D antigen in liver tissue generally adds little to the diagnostic process. Early in the course of infection, acute hepatitis D may be detectable only by performing a test for the IgM form of the antibody. A PCR-based assay also may be performed to detect the presence of RNA from hepatitis D in serum or tissue. This assay is not commercially available, and its use seems to add little to the antibody testing. Because hepatitis D occurs only with concurrent acute hepatitis B infection or as a superinfection of chronic hepatitis B, there is little utility in testing for its presence at the initial workup for viral causes of liver enzyme abnormalities.

What Other Diseases Conditions Or Complications Should I Look For In Patients With Hepatitis B Virus Infection
Acute HBV infection can lead to fulminant hepatitis. Acute liver failure develops in approximately 0.1% to 0.5% of patients.
Prothrombin time, which reflects hepatic synthetic function, is the best indicator of prognosis.
Progression to cirrhosis occurs in up to 20% of patients with untreated chronic hepatitis B. Annual incidence of hepatic decompensation is 5-8% and hepatocellular carcinoma is 2-4% in patients with cirrhosis. Rates of cirrhosis and HCC increase substantially with HBV DNA level, alt levels, HBeAg positivity, and genotype C. Additional risk factors include advanced age, male gender, immunocompromised state, concomitant viral infection , alcohol use, and metabolic syndrome. Furthermore, risk of HCC is higher in patients from Sub-Saharan Africa, positive family history, and smoking.
What Is Viral Hepatitis
Hepatitis means inflammation of the liver. The liver is a vital organ that processes nutrients, filters the blood, and fights infections. When the liver is inflamed or damaged, its function can be affected. Heavy alcohol use, toxins, some medications, and certain medical conditions can cause hepatitis. However, hepatitis is often caused by a virus. In the United States, the most common types of viral hepatitis are hepatitis A, hepatitis B, and hepatitis C.

What Are The Treatments For Hepatitis C
Treatment for hepatitis C is with antiviral medicines. They can cure the disease in most cases.
If you have acute hepatitis C, your health care provider may wait to see if your infection becomes chronic before starting treatment.
If your hepatitis C causes cirrhosis, you should see a doctor who specializes in liver diseases. Treatments for health problems related to cirrhosis include medicines, surgery, and other medical procedures. If your hepatitis C leads to liver failure or liver cancer, you may need a liver transplant.
What Is Hepatic Encephalopathy
Hepatic encephalopathy is an often-temporary neurological disorder due to chronic, severe liver disease. A diseased liver struggles to filter toxins from the bloodstream. These toxins build up in the body and travel to the brain. Toxicity affects brain function and causes cognitive impairment.
People with hepatic encephalopathy may seem confused or have difficulty processing their thoughts. Treatments can remove the toxins and reverse the problem. As liver disease progresses, the condition may worsen and become less treatable. Hepatic encephalopathy is also known as portosystemic encephalopathy .

Listing Of Usual Initial Therapeutic Options Including Guidelines For Use Along With Expected Result Of Therapy
Goals of antiviral therapy are HBeAg seroconversion , HBsAg loss, and suppression of HBV DNA. All patients with cirrhosis should continue treatment indefinitely. Patients without cirrhosis can consider discontinuation after 12 months of achieving above mentioned goal. However, the risk for seroconversion or recurrent viremia persists and patients need to be monitored every 3 months for at least one year after discontinuation of antiviral therapy.

Investigation Of Hepacivirus As Potential Cofactor
Experimental evidence shows that apart from HBV, other viruses, including hepatitis C virus , can provide envelope proteins for human HDV . As we previously detected a high prevalence of hepacivirus in the rodents studied , this possibility was investigated. Overall, we found 4 out of 30 RDeV RNA-positive rodents in which hepacivirus was not detected by the tests initially applied . To exclude having missed hepacivirus detection, we applied RT-PCR assays specifically designed for the E1, NS3, and NS5B genes of P. semispinosus hepacivirus to those samples. All four animals were confirmed to be hepacivirus RNA-negative by these assays as well as by RNA-seq read mapping against P. semispinosus hepacivirus. Statistical analysis of the degree of dependency between deltavirus and hepacivirus infection in individuals was conducted, providing no support for a dependency between the two infections . Also, analyses of sampling site-specific deltavirus and hepacivirus detection rates did not reveal any correlation between deltavirus and hepacivirus , arguing against a linear correlation. Logarithmic and linear regression fits did not yield significant associations either, suggesting that the two viruses follow different patterns of distribution. We conclude that RDeV infection in P. semispinosus does not depend on active hepacivirus infection.

How Can I Confirm The Diagnosis
What tests should be ordered first?
BsAg is the hallmark of HBV infection. It is usually detectable 1 to 10 weeks after an acute exposure to HBV, and approximately 2 to 6 weeks before the onset of clinical symptoms. Most patients who recover from acute hepatitis B clear HBsAg in 4 to 6 months. Persistence of HBsAg in serum for more than 6 months implies chronic infection. Anti-HBs can be detected in individuals who recovered from HBV infection and in those who successfully responded to hepatitis B vaccination.
The antigen HBeAg is a marker of HBV replication and infectivity. Its presence is usually associated with the detection of HBV DNA in serum and a high risk of transmission of infection. However, HBeAg-negative and anti-HBe-positive patients may continue to have active liver disease and moderate levels of HBV DNA in serum. These patients usually have HBV variants with diminished or abolished production of HBeAg.
In patients with acute hepatitis B, serum HBV DNA appears early and may precede the detection of HBsAg.
Chronic hepatitis B is categorized into four phases based on the virus activity and the patientâs immune response to the virus activity . Patients may evolve through some or all phases with variable duration.
Inactive carrier: HBeAg , HBV DNA low, ALT normal
Immune tolerant: HBeAg , HBV DNA elevated, ALT normal
Immune active: HBeAg , HBV DNA elevated, ALT elevated
Immune reactivation: HBeAg , HBV DNA elevated, ALT elevated
When A Transplant Is Needed
Sometimes, the only treatment for fulminant hepatitis is liver transplantation. A persons prognosis after the transplant depends on:
- Severity of the disease before the transplant
- Amount of confusion present in the patient
- Effects on other organ systems, like the kidneys
For those who do qualify for a transplant, the chance of survival is excellent, at 92%.

The most common causes of fulminant hepatitis are:
Generally, viruses are the most common cause of fulminant hepatitis worldwide, whereas Tylenol overdose is more common in the United States and the United Kingdom. Overdose can be both accidental or intentional.
In general, the causes of fulminant hepatitis can be divided into viruses, toxins, and other rare causes.

Genetics Of Infection With Hepatitis B
Several genes, many having to do with the host immune response, have been implicated in the susceptibility to chronic hepatitis B infection. The TNFSF9 gene encodes the CD137L protein, and its expression was found to be significantly higher in patients with chronic hepatitis B infection than in healthy controls. Its expression was also found to be higher in patients who had chronic hepatitis B with cirrhosis, in contrast to those without cirrhosis.
Research done in West Africa, where 90% of the population is infected with hepatitis B, shows that certain human leukocyte antigen class II haplotypes influence the likelihood of chronic infection. For reasons that are not completely clear, persons in the study who were heterozygous for the HLA-DRA and HLA-DQA1 genes were found to be less likely to develop a chronic infection.
Several additional genes are associated with susceptibility to hepatitis B infection. The IFNGR1 gene is located at 6q23.3 and encodes the interferon gamma receptor 1, which has an important role in cell-to-cell communications and can be activated in response to infection, but it is not specific to hepatitis B. Patients with significant dysfunction in this gene have a particular immune deficiency that leaves them extremely susceptible to mycobacterial infections.
