Development of the suppository form of human immunoglobulin preparation with high titers of antibodies to herpes simplex virus types 1 and 2 for the treatment of chronic forms of herpetic disease

Abstract

In spite of the vast arsenal of therapeutic agents, therapy of herpes virus infection (HVI) is very difficult, particularly in pregnant women, newborns and children in the first years of life, as well as in patients with immune deficiency. In this regard, possibility of using immunoglobulins for the treatment of HVI is currently attracting the attention of doctors. The aim of this work was to develop a suppository form of the drug containing donor immunoglobulins with high levels of neutralizing antibodies to herpes simplex virus types 1 and 2 for the treatment of chronic forms of herpetic disease. The study included the following steps: 1) selection of gamma-globulins with high antibody titer for HSV-1 and HSV-2 ELISA test; 2) determination of the level of neutralizing antibodies in the selected series of gamma-globulins in tests in tissue cultures and animals; 3) lyophilization of immunoglobulins; 4) development of the suppository form of the preparation containing gamma-globulin donors with high levels of neutralizing antibodies to HSV-1 and HSV-2; 5) study of the safety of the activity of neutralizing antibodies to HSV-1 and HSV-2 in the suppository form of the drug with hyaluronic acid used as immunomodulator. As the result of this work, immunoglobulin preparation in the suppository form was developed. The developed preparation meets the requirements for safety and efficacy. It is not toxic or pyrogenic. The problems of clinical use of this drug as a method of HVI therapy are discussed.
