Considering that in the HIV infection there is a precocious deterioration of humoral immunity with rapid turn-over of cellular B clones, we have evaluated the conduct of serum lactate-dehydrogenase activity (LD, EC 1.1.1.27) and its isoenzymes in 21 children born from HIV-positive mother respect to a control group (30 subjects). Furthermore we have checked the existence of a probable correlation between those and other clinical and immunologic parameters (total lymphocytes, CD4/CD8, immunoglobulins, classification according to the Atlanta CDC). In seropositive children we saw, respect to those evolved towards P3 stage, a significantly raising of LD4 (also vs. control group) for likely pulmonary parenchyma's damage, LD3 for B immature lymphocytes' increase and a reduction of LD1 (also vs. control group) for mature clones' decrement. Furthermore in seropositive subjects there was the existence of a direct correlation between LD1 and CD4/CD8 values. As such, the evaluation of LD isoenzymes can establish an useful element in the clinical monitoring of seropositive children.

D012044 Regression Analysis Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.
