Hepatitis B : Hepatitis B is a potentially life-threatening liver infection caused by the hepatitis B virus. It is a major global health problem. It can cause chronic liver disease and chronic infection and puts people at high risk of death from cirrhosis of the liver and liver cancer. The virus is transmitted by exposure to infectious blood or body fluids such as semen and vaginal fluids, while viral DNA has been detected in the saliva, tears, and urine of chronic carriers. Perinatal infection is a major route of infection in endemic (mainly developing) countries. Other risk factors for developing HBV infection include working in a healthcare setting, transfusions, dialysis, acupuncture, tattooing, sharing razors or toothbrushes with an infected person, travel in countries where it is endemic, and residence in an institution. Transmission In highly endemic areas, HBV is most commonly spread from mother to child at birth, or from person to person in early childhood. Perinatal or early childhood transmission may also account for more than one third of chronic infections in areas of low endemicity, although in those settings, sexual transmission and the use of contaminated needles, especially among injecting drug users, are the major routes of infection. The hepatitis B virus can survive outside the body for at least seven days. During this time, the virus can still cause infection if it enters the body of a person who is not protected by the vaccine. The hepatitis B virus is not spread by contaminated food or water, and cannot be spread casually in the workplace. The incubation period of the hepatitis B virus is 75 days on average, but can vary from 30 to 180 days. The virus may be detected 30 to 60 days after infection and persists for variable periods of time. Symptoms Most people do not experience any symptoms during the acute infection phase. However, some people have acute illness with symptoms that last several weeks, including yellowing of the skin and eyes (jaundice), dark urine, extreme fatigue, nausea, vomiting and abdominal pain. In some people, the hepatitis B virus can also cause a chronic liver infection that can later develop into cirrhosis of the liver or liver cancer. More than 90% of healthy adults who are infected with the hepatitis B virus will recover and be completely rid of the virus within six months. Treatment There are seven medications licensed for treatment of hepatitis B infection in the United States. These include antiviral drugs lamivudine, adefovir, tenofovir, telbivudine and entecavir and the two immune systemmodulators interferon alpha-2a and PEGylated interferon alpha-2a. Prevention The hepatitis B vaccine is the mainstay of hepatitis B prevention. WHO recommends that all infants receive the hepatitis B vaccine as soon as possible after birth, preferably within 24 hours. The birth dose should be followed by 2 or 3 doses to complete the primary series. In most cases, 1 of the following 2 options is considered appropriate: 1.a 3-dose schedule of hepatitis B vaccine, with the first dose (monovalent) being given at birth and the second and third (monovalent or combined vaccine) given at the same time as the first and third doses of DTP vaccine; or 2.4 doses, where a monovalent birth dose is followed by 3 monovalent or combined vaccine doses, usually given with other routine infant vaccines. The complete vaccine series induces protective antibody levels in more than 95% of infants, children and young adults. Protection lasts at least 20 years and is possibly lifelong.
Acitretin : plasma concentration of methotrexate increased by acitretin . Aspirin : excretion of methotrexate reduced by aspirin Ciclosporin : risk of toxicity when methotrexate given with ciclosporin Cisplatin: increased pulmonary toxicity when methotrexate given with cisplatin Corticosteroids :increased risk of haematological toxicity when methotrexate given with corticosteroids Diclofenac :excretion of methotrexate reduced by diclofenac
