Objective. To study the presentation of Behcet's disease (BD) in the S
audi population and to determine any differences in clinical manifesta
tion and prognosis between men and women. Methods. One hundred ninetee
n patients with BD attending the King Faisal Specialist Hospital and R
esearch Centre (KFSH & RC) and the King Khalid University Hospital (KK
UH) between 1979 and 1992 were studied. Results. The male to female ra
tio was 3.4:1. The mean age was 29.3; oral ulcer was present in all th
e patients (100%), genital ulcer 87%, ocular involvement 65%, skin man
ifestations 57%, and arthritis 37%. Central nervous system involvement
was present in 52 patients (44%) of which 12 had benign intracranial
hypertension (BICH), pleuropulmonary manifestation 16%, deep venous th
rombosis 25%, arterial thrombosis and aneurysm 18%, gastrointestinal m
anifestations 4%, and epididymitis 4%. Significant proteinuria was pre
sent in 9 patients 7.5%, of whom 3 had renal biopsy. The pathergy test
was positive in 15 of 85 (17.5%) patients. HLA-typing was performed f
or 85 patients and HLA B5(51) was positive in 61 (72%) patients compar
ed with 26% general population. Conclusion. Using the Fisher exact tes
t, there was no significant difference in clinical manifestation or pr
ognosis comparing men to women.
