Forty-eight Arab patients with steroid-responsive childhood nephrotic
syndrome were studied for the frequency of HLA-A, -B, -C and -DR antig
ens. HLA-DR7 was significantly increased in the patient group (63% vs.
28%, P = 0.0002) confirming reports of a DR7 association in other eth
nic groups and indicating a universal association with this antigen. H
LA-CW6 was also significantly increased (44% vs. 21%, P corr. = 0.042)
. HLA-DQW1 was significantly reduced in the patients (29% vs. 57%, P c
orr. = 0.012) as was HLA-CW4 (6% vs. 24%, P corr. = 0.042).
