Immunological disorders of increased severity in children with AIDS associated with hepatitis B and C infections.
Two groups of children were set up: children infected with HIV and hepatitis viruses and children infected with HIV, but not with hepatitis viruses, too. The immunological aspects investigated referred to the Ig serum value, the absolute number of T CD4 lymphocytes and the T CD4/T CD8 ratio. The subjects of the first group (in whom hepatitis markers were present) displayed increased IgA and IgM values at a higher rate than those of the second group (54.87% against 32%, 83.3% against 53%), as well as a lowering below 300/ml of the number of T CD4 lymphocytes (50% against 29.4%). On the other hand, increased IgG levels and values below 0.8 of the T CD4/T CD8 ratio were found at similar rates in the two groups of children (77.4% against 80% and 70.5% against 70% respectively). By means of the data obtained, the authors try to point out one of the ways by which hepatitis viruses, considered as a potential cofactor in the AIDS development, contribute to the course of this disease, namely by intensifying the immunological disorders.
