The objective was to study antiphospholipid antibody syndrome (APS or
Hughes syndrome) in two major teaching hospitals in Kuwait. Patients w
ith suspected Hughes syndrome were investigated with tests for anticar
diolipin antibodies (aCL) and lupus anticoagulants (LAC) over 1 yr. Di
agnosis was considered confirmed if significant levels of either or bo
th antibodies with no obvious cause (primary), or with systemic lupus
erythematosus (SLE) or SLE-like illness (including SLE serology) (seco
ndary) were present. Twelve (37.5%; seven females, 58%) primary and 20
(62.5%; IS females, 90%) secondary Hughes syndrome patients were seen
during this period. Patients were Kuwaiti, Middle-Eastern and North-A
frican Arabs (29), Filipinos (2) and White (1). None were from the Ind
ian subcontinent. The main presentation was thrombosis in 75% (arteria
l in 25% and venous in 50%), and recurrent abortions in 50% of married
women. Haematological and dermatological manifestations were limited
entirely to the secondary variety, seen in 25% and 19%, respectively.
Clinical manifestations were severe, leading to death in one, intensiv
e-care management in 31% and with partial or complete warfarin resista
nce or brittleness in 25% Neurological/eye and cardiac manifestations
were not seen, as these patients may be attending separate speciality
hospitals for these diseases in Kuwait. The approximate prevalence of
this syndrome was 2.66/000 admissions in medical wards. Projected to t
he total referral areas of the two hospitals, an approximate figure of
52 patients/million population/year was obtained. Hughes syndrome was
a common problem among Arabs, Filipinos and possibly Whites in Kuwait
. Its manifestations were severe, often requiring intensive-can manage
ment, and in one case it was fatal. Patients from the Indian subcontin
ent were conspicuous by their absence, despite the fact that they were
well represented in all other rheumatic disease groups. Ethnic and/or
geographical factors could be important in this syndrome. To the best
of our knowledge, this is the first report of Hughes syndrome from th
e Middle East.
