The number of patients with end stage renal disease (ESRD) is increasing considerably worldwide. Human Leukocyte Antigens (HLAs) are relevant for the expression of many immunological diseases and contribute to the development of different nephropathies. Therefore, we aimed from the present work to investigate the possible association between the frequency of HLA-A, -B, and -DR antigens and ESRD in Kuwaiti patients awaiting renal transplant.

Background: High levels of soluble CD30 (sCD30), a marker for T-helper 2-type cytokine-producing T cells, pre or post-renal transplantation serves as a useful predictor of acute rejection episodes. Over the course of 1-year, we evaluated the accuracy of serial sCD30 tests to predict acute rejection episodes versus other pathologies that affect graft outcomes.

Patients And Methods: Fifty renal transplant recipients were randomly selected to examine sCD30 on days 0, 3, 5, 7, 14, and 21 followed by 1, 3, 6, and 12 months.

While conversion of stable renal transplant recipients (RTR) from calcineurin inhibitors (CNI) to sirolimus (SRL) is safe and effective, it is still under investigation for recent, high-risk cases. We studied the long-term effects of conversion of high-risk subjects maintained on a CNI, mycophenolate mofetil, plus steroid regimen to SRL, mycophenolate mofetil, plus steroid on graft and patient outcomes. We retrospectively reviewed the first 100 RTR converted to SRL treatment over approximately 5 years.

The presence of IgG antibodies in the pretransplant cross-match (XM) test results in hyperacute rejection, but IgM antibodies are inconsequential. The XM should be able to differentiate between IgG and IgM antibodies. This study evaluated 3 methods.

The prevalence of inflammatory bowel disease (IBD) after renal transplantation is affected by the immune tolerance and the modality of immunosuppression. Mycophenolate mofetil (MMF) may have a promoting effect on the development of posttransplantation erosive enterocolitis and a Crohn's disease-like pattern of colitis. We have presented a 40-year-old man with end-stage renal disease due to chronic glomerulonephritis who commenced hemodialysis for 2 months before receipt of a live unrelated renal transplant.

Cyclosporine (CsA) microemulsion has been the mainstay immunosuppressive agent for renal transplant recipients for years. A single daily dosing of cyclosporine (SD) is rarely used. The objective of this study was to evaluate the efficacy of SD versus twice daily dosing of CsA.

Objective: The area under the concentration-time curve of cyclosporine microemulsion is the best measure of the absorption and beneficial effects in renal transplant recipients. We sought to determine the best method of monitoring cyclosporine levels in these patients.

Methods: Prospective evaluation of peak cyclosporine blood levels and area under the curve monitoring were performed for 1 year in 65 renal transplant recipients (study group).

We prospectively analyzed the impact of post-transplant infections on the renal function in 532 stable renal transplant recipients (M=340; F=192) over a period of 5 years. Their age ranged from 3-75 years (40+14 years). During the follow-up period, 52 patients expired and 64 lost on followup.

Pemphigoid gestationis (PG) is a rare autoimmune disease of pregnancy. We report a series of 22 cases of PG in Kuwait. They constituted 18% of all the autoimmune bullous diseases registered in our centre over a span of 11 years.

A total of 80 Kuwaiti children with alopecia areata (AA), without clinical evidence of thyroid disease, were screened for the presence of thyroid abnormalities, and 50 unrelated children with AA were tissue typed for human leukocyte antigen (HLA) class I and class II antigens. Thyroid abnormalities were detected in 14 children (17.5%).

Objective: To retrospectively review the long-term outcome of renal transplant in diabetics at Mubarak Al-Kabeer Hospital and Hamad Al-Essa Organ Transplant Center, Kuwait from 1983 to 1998.

Methods: There were 631 renal transplant patients, comprising 79 (12.5%) patients with pretransplant diabetes mellitus (pre-TDM), 117 (18.

A total of 305 consecutive Kuwaiti children with psoriasis were studied for clinical features and 50 children were tissue typed for HLA class I and class II antigens. The salient features of psoriasis in these children included: female preponderance (M : F ratio, 1:1.5); peak age of onset between 2 and 8 years; scalp as the most common site of onset (30%); scalp and extensors of legs as commonly affected sites (52.

Background: Nocardiosis has emerged as an important bacterial disease among renal transplant recipients, leading to considerable morbidity and mortality. Apart from the increasing problem of resistance in pathogenic nocardiae, the spectrum of species causing disease has enlarged in recent years. There are no published reports on nocardiosis from Middle-East countries.

The presence of cytotoxic HLA antibodies (Ab1) against donor lymphocytes in pretransplant sera is almost always associated with rapid rejection of the renal transplant. We have investigated the possibility that antiidiotypic antibodies (Ab2) to cytotoxic HLA antibodies might modulate the immune response and favorably influence renal allograft outcome. The role of antibodies (Ab3) which potentiate the cytotoxic effect of Ab1 was also studied.

The survival of a one haplotype, mismatched living-related renal allograft is improved by donor specific transfusion (DST) before transplantation although the mechanism is unclear. The major risk of DST is sensitization of the recipient to donor lymphocytes precluding transplantation. Fifty prospective recipients of a living related transplant received either DST with cyclosporin A (group I) or DST alone (group II).
