Известно, острые кишечные инфекции (ОКИ) до настоящего времени занимают одно из ведущих мест в инфекционной патологии у детей. Как показали многочисленные наблюдения, у детей, перенесших ОКИ, неблагоприятными последствиями могут быть постинфекционные функциональные гастроинтестинальные расстройства.
Activation of herpesvirus infection in HIV-infected patients, in addition to a general increase in HIV replication, occurs with increased release of HIV virions in areas of herpetic skin rashes, which do not always have the appearance characteristic of herpes. The most important thing is that in this case particles of a mixed phenotype can be formed - HIV virions, "dressed” in the herpes shell. Such "camouflaged" particles, unlike ordinary HIV virions, are capable of infecting various types of cells, including epithelial cells and fibroblasts, thereby giving a productive HIV infection, that is, it becomes possible to become infected with HIV through contact with the skin and mucous membrane.
It has now been established that with viral hepatitis, incl. and with Chronic viral hepatitis С (CHC), a universal mechanism of hepatocyte death develops through the increased production of reactive oxygen species, causing excessive lipid peroxidation of membrane structures (Glushkov S.I., 2016; Aripov O.A., 2018.). In this case, the main function of protection is when lipid peroxidation (LPO) is activated, the antioxidant defense system (AOD) of cells is performed, the deficiency of which becomes one of the factors for the activation of pro-oxidant systems. An important point in the effectiveness of AOP is the balance of SOD and catalase. A decrease in the activity of one of the AOP enzymes can lead to excessive accumulation of reactive oxygen species and membrane damage. An imbalance in the activity of the LPO and AOP systems is the basis for the onset of cellular destruction [Bueverov A.O. 2012].
