Establishment of anti-Epstein–Barr virus (EBV) cellular immunity by adoptive transfer of virus-specific cytotoxic T lymphocytes from an HLA-matched sibling to a patient with severe chronic active EBV infection

We describe an experience of a specific immune transfer treatment in a patient with chronic active EBV infection. The patient had low anti-EBV T cell-mediated cytotoxic activity in his peripheral blood mononuclear cells (PBMC), which may have been the primary cause of the disease. An EBV-specific cytotoxic T lymphocyte (CTL) line was established from PBMC obtained from the patient’s sister whose human leucocyte antigens (HLA) are identical to patient's. The patient received three courses of intravenously administered CTL at 3-week intervals. The number of the cells was increased with each course of treatment. After infusion of the T cell line, anti-EBV CTL activity was detected in the patient's PBMC. CTL activity increased markedly after the second course of immune transfer therapy. The amount of EBV DNA in the patient's plasma showed transient but repeated decreases. Serum levels of tumour necrosis factor-alpha (TNF-α), which had elevated before treatment, began to decrease after initiation of treatment. No adverse effects were directly associated with CTL infusions. Despite having previously received a pneumococcal vaccine and prophylactic antibodies, the patient died of infection caused by Streptococcus pneumoniae bacteraemia 27 days after the third infusion. Although the long-term efficacy and safety of this therapy remains to be established, our findings suggest that adoptive transfer of CTL specific for EBV obtained from an HLA-matched donor might be a promising treatment for patients with chronic active EBV infection.     

Characteristics of juvenile dermatomyositis in Japan

Questionnaires were sent to 1290 hospitals in Japan asking for data on patients with juvenile dermatomyositis (JDM) diagnosed between June 1984 and May 1994. Of the 204 patients identified by these questionnaires, 102 met the criteria for JDM. JDM is categorized into three subtypes: Banker-type JDM , Brunsting-type and fulminant-type; patients with the latter exhibit markedly elevated serum levels of creatinine phosphokinase (> 10 000 U/mL) and appear to be at risk of renal failure. Cutaneous manifestations were present in 98% of patients and preceded the appearance of other symptoms. This tendency is one of the reasons for the difficulty in some cases in diagnosing the onset of JDM. Better criteria for early treatment of JDM are needed. The results of the present study suggest that itching and calcinosis are factors that indicate a poor prognosis in patients with JDM. Muscle enzyme levels do not always reflect disease activity, suggesting that methods other than measurement of muscle enzymes, such as measurement of the levels of neoprerin and von Willebrand factor antigen, as well as magnetic resonance imaging should be used to be evaluate disease severity. Patients with Brunsting-type JDM who exhibit dysphagia and antinuclear antibody positivity and patients with Banker-type JDM should be treated aggressively. Pulse therapy should be selected as the initial therapy in patients with fulminant-type JDM.

Eye Movements during Perception of Pictures in Chronic Schizophrenia

Using a device of our own built eye movements during the perception of some pictures were examined in 24 chronic schizophrenic and 20 normal subjects. While they were shown each of 4 pictures for 30 seconds, we plotted the points on which the subject's eyes fixed for a short time and observed their traces. We also recorded EOG during the eye closure for 17 cases of these schizophrenic subjects. Additional observations and comparison of eye movements during the perception with EOG findings led to the following conclusions: 1. Concerning the degree of diffusion of the eye's fixation points, the moving range of the gaze in chronic schizophrenics was much more limited than in normal subjects. 2. There was observed rather large number appearance of the small rapid eye movements with closed eyes in the schizophrenic subjects who showed limited moving range of eye's fixation points. Chronic schizophrenic patients probably look at a certain part vaguely. This may be due to their decreased motivation and lack of interest in trying to get information about the pictures and to cognize them.     

HNK-I antibody reacts with peripheral nerves and sweat glands in the skin

The distribution of Leu-7 antigen was investigated using immunoperoxidase staining technique. It was found that HNK-I monoclonal antibody reacted with peripheral nerves and sweat glands (both apocrine and eccrine) of the skin. HNK-I antibody is a new marker for them, and may help to elucidate the nature of some skin tumours.
