Immunological outcomes in infants with ROP after dexamethasone and aminophylline.

This research aims to improve anaesthesia services given to preterm infants by the use of dexamethasone and aminophylline administrated under sevoflurane, and to analyze its effect on the cell-mediated immunity (CD4+CD25+Foxp3+(T-reg) and CD4+CD25highFoxp3+CD127low). We have examined 74 premature babies with retinopathy of prematurity (ROP) at the 3-5 stages during the 25-32 week gestation period (1-6 months after birth). Both immunomodulators had no significant effect on clinical parameters after one dose (P > .

[Disorders in the immune regulation and hemostasis as factors triggering the proliferative retinopathy in diabetes mellitus].

A comprehensive clinical- immunological- and-hemostasiological study of the lachrymal fluid and blood of 105 patients with diabetic retinopathy (DR) showed that an "extreme" activity of the local antibody-dependent response to collagens, DNA, cytokine, TNF-alpha, increased levels of the circulating immune complexes (CIC) and of antibodies to DNA in the blood serum as well as local immune insufficiency and deficiency of free antibodies to collagens and TNF-alpha in the lachrymal fluid and serum during the onset of proliferative forms and traction retinal detachment are the key manifestations of the immune pathology in a progressing DR. Signs of hypercoagulation, free heparin deficiency, a reduced activity of fibrinolysis and insufficiency of the anti-thrombin system were detected with the development of the chronic syndrome of disseminated intravascular blood coagulation. Trends of the immunohemostatic correction of the activity of the local and systemic autoimmune responses and of hemostasis were substantiated during the generally accepted therapy of diabetes mellitus and of systemic micro- and-macroangiopathy.

[Antibodies to types II and IV collagens, tumor necrosis factor-alpha and circulating immune complexes in lacrimal fluid and serum of patients with diabetic retinopathy and different stages].

Clinical and immunological examinations are carried out in patients with preclinical, nonproliferative, preproliferative, and proliferative diabetic retinopathy (DR). On the whole, DR is characterized by a notable increase in antibody-dependent immune response, associated with appearance of antibodies to collagen of the II and IV types in the lacrimal fluid and serum, with the "local" reactions predominating. The level of reactions of cellular autoimmune response (tumor necrosis factor-alpha) and cell-to-cell reactions in the lacrimal fluid and serum is low.

[Heparin inhalations combined with intravenous laser exposure of blood in patients with diabetic retinopathy].

Heparin inhalations combined with intravenous laser exposure of the blood are effective in patients with nonproliferative, preproliferative, and proliferative diabetic retinopathy. Clinical effect consisted in decrease of edema in the macular area, partial resolution of hemorrhages, a tendency to decrease in the caliber of veins, improvement of visual acuity, and extension of visual field. Immunological studies revealed immunomodulating effect of heparin inhalations and intravenous laser exposure of the blood, manifesting by decreased levels of pathological circulating immune complexes and increased concentrations of immunoglobulins, mainly IgG and IgM.
