How is giant cell retinitis treated?

summary

There are many possible infections caused by cytomegalovirus, which can damage the reproductive, urinary and central nervous systems. Therefore, in the presence of cytomegalovirus, timely treatment is quite critical, but to ensure symptomatic, so as to ensure the curative effect. Today let me tell you how to treat giant cell retinitis?.

How is giant cell retinitis treated?

First, ganciclovir (DHPG) can prevent CMV from spreading. If combined with high titer of anti CMV immunoglobulin, it can reduce the mortality of CMV pneumonia complications after bone marrow transplantation. If CMV infection is resistant to propoxyguanosine, foscarnet can be used. Although it can reduce CMV diffusion for a long time, the effect is worse than the former. The development of CMV live vaccine abroad can induce the production of antibodies, but the elimination of the carcinogenic potential of the vaccine remains to be solved.

Second, immune prevention and treatment is still under research and exploration. The inactivated vaccine had no significant preventive effect on CMV induced intracellular infection. When the primary infection of CMV and / or the presence of CMV antigen in amniotic fluid cells are found in early pregnancy, the pregnancy should be terminated. Live attenuated vaccine can make the vaccinees produce antibodies. It can also produce cellular immunity to CMV and reduce the occurrence of symptomatic CMV infection. CMV high immunoglobulin has a protective effect on symptomatic CMV infection in CMV negative bone marrow transplant recipients, but it can not prevent reinfection. Wash hands carefully after contacting urine or saliva to prevent CMV infection.

Third, to prevent CMV infection caused by fresh blood transfusion, the following methods can be used: (1) using frozen blood or washed blood; ② Blood should be stored for more than 48 hours before transfusion; ③ Using irradiated blood; ④ Use a blood filter to remove giant cells from the blood.

matters needing attention

(1) carry out conscious physical training. Improve the immune function and disease resistance of the body, especially women of childbearing age, in order to reduce the serious harm of cytomegalovirus to the fetus. (2) pregnant women or patients with chronic consumptive diseases and low immunity should be protected from the source of infection. (3) pay attention to environmental hygiene and food hygiene. (4) those with positive cytomegalovirus in breast milk should not breast feed.
