HYPERGAMMAGLOBULINEMIC PURPURA OF WALDENSTROM AND RO/SSA AUTOANTIBODIES. 9. Mivapma”. T. Fboto. and T. Shirai. Department of Dermatology, Nara Medical University, Nara, Japan Seven out of nine patients (78%) with hypergammaglobulinemic purpura of WaldenstrBm (HGP) were found to have antibodies to Ro/SSA. In all of the seven patients, associated diseases were recognized in 2-15 years. Five had primary SjUgren’s syndrome, one had rheumatoid arthritis, and one had systemic lupus erythematosus with Sjirgren’s syndrome and thyroid&is. Our study suggests that screening for antibodies to Ro/SSA, especially to the 52kd component of Ro/SSA, is important in the diagnosis of patients with HGP, and might be helpful in predicting prognosis.

TREATMENT WITH LIP0 PGE I PREPARATIONS IN PATIENTS WITH DIFFUSE CONNECTIVB TISSUE DISEASE AND PATlEN’SS WITH NEURALGIA -EVALUATION BY ACCELERATION PULSE WAVE. T.Okuda, Y.Umezawa. M.Hirata. T.Dh-i and M. Kona. Department of Dermatology, Tokyo Medical College, Tokyo, JAPAN. Lipo PGEl preparations have shown to be e&etive for the treatment of skin manifestations associated with diffuse cona&ive tissue disease in several studies. There are, however, oo objective aiterla for evaluating the efficacy of the drug. We investigated whether the efficacy could be asxased by ecceleretion pulse wave. we studies 10 patients tith @#use conne&tive tissue disease (4 SLE, 4 PSS and 2 detmatomycaltis) and 10 patients with neuralgia subsquent to herpes wster es contml. Accclcretion pulse wave was measured at the sclerodaetyly or cold spat of the finger tip ia patients with diffuse comt&ive tissue disease and at the finger tip oppo& the a&&ted part in patients with neuralgia, before and after 1Oug of Lipo PGEl dissolved in 5Oml of physiological saline was infused intravenously over 5 &titer.

and A. Ohkews,a Depanment of Dermatology, Hokkaido University School of Medicine, Sappom. Japan. Several lines of’ clinical and experimental ewdencc suggest that spxific immunological mechanisms are involwd in the pathogenesis of generalized pustular psoriasis (GPP). We dcmonstmti that the scra fmm GPP patients contained higher amounts of ILlh IL-6, IL8 and TNF-a than those of control individuals. It is well known that ILlg can te acause of fercr and Induces othercytokine production. In this study, we examined ILIP production of patients peripheral bleed mononuclear cells (PBMC) and monocytes. PBMC were separated b) Ficoll and adherent momrytes-enriched fractions were further plritied by incubating PBMC on tissue culture plates for 2 hours and removing non-adherent cells. fbesc PBMC and monw~vs-enriched fractions were stimulated by various stimuli for 48 hours and sup;mataants were assayed for ILIe by ELISA. The results showed that LPSsumulated PBMC and monocytes from GPP patients both produced approximately twice more Il.-lp than those from normal individuals. supporting a view that IL-16 plays an imporlnnl role in the pathogcncsis of GPP
