Recent studies have revealed that encephalitis lethargica (EL) may not be related to influenza virus infection but more likely to be a post-infectious autoimmune disease. The diagnostic clinical criteria for EL like illness include subacute hypersomnolence and ophthalmoparesis followed by Parkinsonism, oculogyric crisis, neuropsychiatric disorders and central respiratory abnormality. Recently, Magnetic Resonance Imaging (MRI), which depicts hypersignal intensity on T2 weighted, and FLAIR images at midbrain, tegmentum, and basal ganglia, have been very helpful diagnostic tests in EL like illness. Nevertheless, EL like illness has never been reported in Thailand. A 17 year-old man presented with hypersomnolence one week before admission. Physical examination revealed drowsiness and ophthalmoparesis. MRI showed bilateral hypersignal intensity lesions on T2 weighted and FLAIR images at midbrain, basal ganglia and temporal lobes. CSF studies showed normal profiles. CSF-PCR for herpes simplex virus, varicella zoster virus, cytomegalovirus, Epstein-Barr virus, Pan-Enterovirus and Westnile virus were negative. CSF Dengue and Japanese encephalitis virus hemagglutination test were negative. He was treated with intravenous dexamethasone and immunoglobulin. Somnolence and ophthalmoparesis were improved. Two months later, he developed schizophreniform features and Parkinsonism. MRI revealed improvement of midbrain and basal ganglia lesions. CSF studies showed normal CSF profiles while oligoclonal bands were positive. Autoimmune profiles and serological tests for post-streptococcal infection as well as syphilis were negative. Thyroid function tests and serum ceruloplasmin were within normal limits. Levo-Dopa, clonazepam and sodium valproate had been prescribed and the clinical syndrome was gradually improved.

The paper deals with the topical theme--the state of antioxidant protective components in influenza infection. The values of catalase in red blood cells and those of ceruloplasmin in plasma were studied as an indicator of antiperoxide defense. The patients were grouped according to the severity of their condition and associated complications. The studies revealed a regular reduction in plasma ceruloplasmic levels at the height of influenza. In the waning period of clinical symptoms and in early convalescence, the parameter under study did not differ from that of healthy individuals. At the same time, the trend in influenza showed a significant increase in red blood cell catalase levels with the maximum values at the height of the disease and their normalization in early and late convalescence.

The present study assesses copper metabolism of the host organism as a target of antiviral strategy, basing on the "virocell" concept. Silver nanoparticles (AgNPs) were used as a specific active agent because they reduce the level of holo-ceruloplasmin, the main extracellular cuproenzyme. The mouse model of influenza virus A infection was used with two doses: 1 LD50 and 10 LD50. Three treatment regimens were used: Scheme 1-mice were pretreated 4 days before infection and then every day during infection development; Scheme 2-mice were pretreated four days before infection and on the day of virus infection; Scheme 3-virus infection and AgNP treatment started simultaneously, and mice were injected with AgNPs until the end of the experiment. The mice treated by Scheme 1 demonstrated significantly lower mortality, the protection index reached 60-70% at the end of the experiment, and mean lifespan was prolonged. In addition, the treatment of the animals with AgNPs resulted in normalization of the weight dynamics. Despite the amelioration of the infection, AgNP treatment did not influence influenza virus replication. The possibility of using nanosilver as an effective indirectly-acting antiviral drug is discussed.
