Patterns of natural killer cell function activation in response to interferon in chronic HBsAG positive hepatitis: relationship with the state of viral infection and with the early clinical response.

In an effort to define immunobiological parameters identifying "responders" vs "non-responders" to IFN among hepatitis patients, 16 patients with chronic active hepatitis were screened for changes of Natural Killer cell activity (NK). 10/16 patients replicated the hepatitis B virus (HBV-DNA positive) whereas 6/16 replicated the defective B virus associated delta virus (HDV-RNA positive). Patients received 9 MU/3x/weekly/3 months of recombinant IFN alpha A. Mean NK activity of the HBV-DNA patients rose significantly from 29.9 +/- 5.3 to 45 +/- 4.7 during therapy, whereas the 6/16 HDV-RNA positive patients did not show any significant increase of NK activity. Interestingly, individual HDV-RNA positive patients exhibiting boosted NK activity also showed improvement of disease confirmed by clearance of intrahepatic delta antigen at one year. No such a correlation was found amongst the HBV-DNA positive patients. These data indicate that in spite of widespread individual variability, IFN-mediated NK boost may herald delta clearance and help in identifying "responders" and "non-responders" in IFN trials.

[Deep cerebral lesions: neuro-rehabilitative aspects].

All 21 patients under rehabilitative care, who were followed by the authors, suffered from language and motor deficits, the latter being part of a deficient hemi-syndrome caused by deep vascular cerebral lesions, in both thalamic (8 patients) and basal ganglia (13 patients) sites. All subjects, on entry and 3 months after treatment, underwent a language test, routine tests, De Renzi-Vignolo's Token test and neuromotor evaluation, to study muscle tone, the presence of pathological synergies, sensitivity, active motility and functionality. On entry, patients with thalamic lesions had fewer problems than those with lesions of the basal ganglia at both symbolic and neuromotor levels. A better recovery of the functional capacities in the treatment period was thus achieved.
