[Evolution and prognosis of retrobulbar optic neuritis as the initial symptom of multiple sclerosis].

In 61 of 300 patients suffering from multiple sclerosis, disease onset was retrobulbar optical neuritis. Comparing the clinical data of these patients with those of the remaining 239 cases, the following typical features were observed: in patients with optical neuropathy, disease onset is more frequently acute and course, in the early years of the disease, is in fits and starts. Recurrence frequency is higher in these patients but not significantly so. Prognosis, deduced from the analysis of degrees of invalidity, does not differ substantially between the two groups. Current techniques of diagnosing multiple sclerosis in patients with retrobulbar optical neuritis are also discussed.

[Visual evoked potentials and the E-UFA test. Laboratory contribution to the diagnosis of multiple sclerosis].

Visual evoked potentials (VEPs) and electrophoretic mobility test of erythrocytes (E-UFA test) were compared in 50 multiple sclerosis (M.S.) patients as diagnostic tests. Abnormal VEPs were recorded in 35 patients. E-UFA test was found positive in 31 cases. With respect to Mc Alpine diagnostic criteria, 26 out of 33 definite M.S., 6 out of 9 probable M.S. and 3 out of 8 possible M.S. cases had abnormal VEPs. A positive response in E-UFA test was observed rispectively in 16, 8, 7 patients. Complessively 48 cases (96%) had an abnormal response to the one and/or to the other of the two tests, which apper complementar in early diagnosis of M.S.

Erythrocyte unsaturated fatty acid test (E-UFA test): a biological test to detect optic neuritis as initial feature of multiple sclerosis.

Retrobulbar optic neuritis, though suspicious is not always considered as a possible onset of MS. For this reason we submitted to the E-UFA (erythrocyte unsaturated fatty acid) test, 41 subjects who suffered from one or several episodes of retrobulbar optic neuritis with no other neurological signs. The test was positive in 14 subjects (34, 1%).

2 [(methylsulfinyl) acetyl] pyridine (Oxisuran): a new immunosuppressive agent in EAE.

The authors discuss the effects of a new immunosuppressive agent on the development of EAE. Animals (albino rabbits) were inoculated with an encephalitogenic emulsion, according to Kies' method, whereas a control group was inoculated by a physiological saline solution. Some animals were treated by Oxisuran in the first day after challenge; some others after initial symptoms (18th day). Thirty days after challenge, the animals were sacrificed. No toxicity was found in thoracic and abdominal structures neither in blood count. Pharmacological effectiveness of Oxisuran is well documented either in pretreatment or in therapy; the course was positively influenced in animals, when treated after the appearance of initial symptoms.

Heterogeneity of human T lymphocytes to bind sheep red blood cells in multiple sclerosis patients and controls.

The present studies were performed as a result of the report that the human T-cells may be composed of heterogeneous subpopulation in the sense of their ability to bind SRBC. In this paper, the diversity of human peripheral lymphocytes in M.S. patients, other neurological diseases and controls were investigated by means of an interesting approach based on the heterogeneity of humnan T-lymphocytes examined by the rosette formation of SRBC (E rosette) in two different reaction media.

E-UFA test in multiple sclerosis.

Field et al. have recently suggested a blood test for multiple sclerosis based on determination of the absolute electrophoretic mobility of erythrocytes alone and in the presence of linoleic acid (LA) or arachidonic acid (AA). We attempted to reinvestigate this phenomenon in an Italian population.

Study of the relationship between rubella virus and encephalitogenic factor in experimental allergic encephalomyelitis.

The Authors research in the sera of 30 rabbits affected by E.A.E. the connection between encephalitogenic factor and rubella virus. They dose the antibodies against rubella virus and encephalitogenic factor before the challenge by BP, after 15 days and after 30 days. While in the first control no response either to the virus or to BP was evidenced, in the two following controls, the sera of the rabbits recognized immunologically both rubella virus and the myelinic components.

Clinical picture of multiple sclerosis with late onset.

A group of 47 patients (multiple sclerosis (M.S.) diagnosed according to Schumacher's criteria) with age at onset over 40 years, was studied by statistical analysis and compared with a control group (100 M.S. patients with onset between ages 18 and 38). The following features appear peculiar in this group: --the most frequent initial symptoms are motor disturbances --the onset is generally monosymptomatic --the course is generally progressive and more severe than that of controls, as seen by Kurtzke's Disability Scale, relapse rate, interval between first and second attack --the course is more severe when the onset is progressive and characterized by motor disturbances.

HLA-A3 linked C3 deficiency in multiple sclerosis.

Many workers claim variations in quantity of functional activity of several components in the complement system in M.S. patients. Studies were performed in 58 M.S. patients, typing for HLA-SD specifities and C'3 complement component. We have been able to confirm a significant correlation between the hypocomplementaemic group (31.03%) with HLA-A3. In this connection we present some considerations on complement system and M.S.

[Oral contraception and multiple sclerosis].

The uncertain question of the use of oral contraceptives by women with multiple sclerosis is discussed. Reference is made to results observed in animals with experimentally induced allergic encephalitis subjected to oestroprogestin management. The course of M.S. during pregnancy is examined and the effects of blood lipid changes produced by oestrogens and progesterone, on the assumption that M.S. is due to a deficiency of unsaturated fatty acids. Lastly, attention is directed to interference with immunity, clotting, and platelet changes, these being factors in the spread off the disease. The data point to a protective rôle on the part of oestrogens, while the picture for progesterone is less conclusive. It would seem that these biological and immunological findings justify the use of oral contraceptives in subjects with M.S., though due caution is imposed by the absence of clinical and epidemiological data.

[Biochemical aspects of lipid metabolism in multiple sclerosis].

The biochemical features of lipid metabolism in multiple sclerosis are discussed and the contribution made by work on the aetiopathogenesis of the disease is illustrated. Reference is made to diagnostic tests (E-UFA and MEM tests), whose premisses are based on lipid metabolism. A link between biochemical and immunological research in this field is put forward.
