Sclerosis multiplex in gypsies.

MS rarely occurs in gypsies in Hungary despite the high DR2 frequency. When it does occur, it has special features more resembling that of Asians than Central Europeans. In order to find correlation between the clinical observations and the immunogenetical data, the distribution of DQw1 subtypes was investigated by means of Eco RV - DQ beta RFLP in DR2 positive healthy gypsies and Hungarians, as well asin DR2-positive Hungarian and unselected gypsy MS patients. DQw6 correlated with MS susceptibility in Hungarians. This allotype was completely absent in healthy DR2-positive gypsies. DR2-positive gypsy MS patients, however, carried DQw6. No correlation of complement allotypes with the occurrence of MS was found in Hungarians, while a striking elevation of C4 Q0 occurred in gypsy MS patients compared with healthy individuals in the gypsy group. The absence of the DR2, DW2, DQw6 haplotype, and the frequency of C4A Q0 in healthy gypsies seems to be associated with the low MS prevalence, but genes outside this region might also influence the MS susceptibility.

Positive autoradiographic findings in brains of four MS patients.

Autoradiography of brain slices from 4 multiple sclerosis (MS) and 9 control patients was performed. After 6 weeks of exposure the exact picture of the white matter appeared on the X-ray films in all cases with MS, but only in one of the controls. The high level of autoradiographic signal from MS white matter suggests that an abnormal accumulation of radioactive trace elements takes place within the brains of MS victims.

Adult-onset rapidly progressive spinal muscular atrophy of shoulder girdle with gammopathy.

The paper reports on clinical and pathologic findings in a 51-year-old man who presented with rapidly progressive spinal muscular atrophy associated with relatively early respiratory paralysis. Clinical diagnosis was based on typical EMG, and bioptic and enzyme findings. In the CSF protein and cell content were normal, the IgG concentration was high, the IgG/Alb quotient increased, intrathecal synthesis of IgG was evident, and oligoclonal gammopathy was found. All of these findings generally appear in neuroallergic diseases. Total loss of anterior-horn cells, demyelination of fasciculus cuneatus and spinothalamic pathways, as well as round Lafora-body like inclusions, preponderantly in the white matter, were observed with light microscopy. Electron microscopic examination revealed reoviruses in the glia cells of the damaged motor zone.
