The importance of immunosupression in the development of the heavy form of cytomegaloviral infection in newborn children

Objective : to study the features of disorders in T and B cell immunity and the synthesis of serum immunoglobulins of classes IgA, IgM, IgG with the aim of predicting severe cytomegalovirus infection (CMVI) in newborns. Research methods : 133 newborns with cytomegalovirus infection were examined. Lymphocytes were typed to differentiation clusters CD3, CD4, CD8, CD20 using monoclonal antibodies, IMMUNOTECH (France). The expression of membrane markers of immunocompetent cells was determined using a Beckman COULTER EpicsXLII ow laser cytouorimeter. Depending on the severity of the condition, all children were divided into two groups: 1 — CMVI, severe form — 60 people (45,1%); 2 CMVI, moderate form — 73 people (54,9%). Results . Using the «classication trees» method, we were able to develop a differentiated approach to the prognosis of a severe form of CMVI in newborn children. Systems of inequalities were obtained, four of which classify a subgroup of newborns with severe CMVI. Conclusion: the proposed diagnostic rules can be considered screening markers for prognosis of a severe form of CMVI in newborns.
