Successful living related kidney transplantation across an anti-donor HLA antibody.

In preconditioning highly sensitized kidney transplant candidates, renal allograft outcomes have been better when the serum titer for class I anti-HLA donor-specific antibody (DSA) is low in the recipient at the time of transplantation. However, the ideal level to which the titer should be lowered is still controversial. We report a primary living related kidney transplant in a 34-year-old highly sensitized woman (pretransplant panel-reactive antibody=70%) with end-stage renal disease secondary to chronic glomerulonephritis. We sought to desensitize by lowering the DSA titer specifically to 1:4 pretransplant. A standard complement-dependent cytotoxicity cross-match with her donor (sister) was repeatedly negative, although she was positive for class I antibody against her mismatched HLA antigen (A*2402) at a titer up to 1:16 by the single-antigen flowbead assay. The target DSA titer of 1:4 before transplant was achieved by 12 sessions of plasmapheresis (PP) over 7 weeks, plus two intravenous immune globulin infusions (IVIG) (500 mg/kg/infusion). The patient outcome was excellent. Neither IVIG nor PP was needed posttransplant. The serum creatinine ranged between 0.5 mg/dL and 1.2 mg/dL, and no rejection episode was documented at 28 weeks posttransplant. Therefore, we encourage the use of IVIG and PP to lower the DSA titer to at least 1:4 before kidney transplantation in highly sensitized patients. Large prospective trials are needed to establish a consensus for pretransplant risk assignment and to evaluate the need for desensitization.

[Cancer of the cervix uteri in Tunisia. Clinical presentation and development over a 10-year period]. / Le cancer du col utérin en Tunisie. Présentation clinique et évolution au cours d'une période de 10 ans.

Carcinoma of the cervix is still common in Tunisia, where it occupies second place among malignant diseases in women. Accounting for 17% of the female population of the National Cancer Institute of Tunis, it is preceded only by breast cancer (27%). Study of the factors concurrent with the origin of carcinoma of the uterine cervix seems to indicate that its decrease is secondary to the lowered average age at marriage, to the fall in the reproduction rate among the population at large, and to improved socio-economic conditions among the poorer classes. Study of clinical features observed during two separate periods of 10 years shows a modification in the physiognomy of this cancer, with, notably, a larger frequence of lower stages (45% of stage II in 1984 vs 20% in 1974) and a slight tendancy towards the discovery of smaller non - or early - infiltrating tumors (4% in 1984 vs 0% in 1974). Efforts must continue to be made in the domaine of early detection, especially among the "high risk" population.

[Diagnostic and therapeutic thoracoscopy in 83 cases of chronic pleurisy]. / Thoracoscopie diagnostique et thérapeutique dans 83 cas de pleurésies chroniques.

From May 1983 to June 1985 the authors performed a thoracoscopy as a diagnostic and therapeutic objective in 83 patients with chronic recurrent pleurisy; amongst these patients, 69 had know intra or extra thoracic cancer and the other 14 presented with an isolated pleurisy. Eight other patients had pleural carcinomatosis proven by needle biopsy and had pleural talc introduced by thoracoscopy. The examination was performed under local anaesthesia with neuroleptanalgesia; a rigid 7 mm diameter thoracoscope was used; the biopsies were performed uniquely on the parietal pleura using tropical forceps. The outcome was uncomplicated with no deaths nor any serious complications due to the method. The sensitivity of the pleural biopsy was 91.5% or 76 positive biopsies out of 83. 73 biopsies were metastatic and 3 were tuberculous pleurisies. The macroscopic appearance was strongly suggestive of malignancy in 78 patients and appeared inflammatory in 13, of whom 9 cases were positive on biopsy. The authors performed a pleural talcage in every case; a lasting pleural adhesion was obtained in 66 patients but regrettably there were 14 failures, the effusion recurring after removal of the drain. The authors stress the reduced number of incidents of pleural effusion, which confirms the good tolerance of pleural endoscopy.

Simultaneous pediatric kidney transplantation and ureterocystoplasty in a 20-month-old boy.

Kidney transplantation (KT) in children with end-stage renal disease and an abnormal bladder poses a complex management challenge. Ureterocystoplasty (UC) has been previously reported in older children with non-compliant bladders, but the timing and technique of repair are controversial. This case reports the youngest patient, a 20-month-old boy to undergo successful single-stage UC and living-related KT. UC was performed because of a fibrotic, non-compliant bladder. A temporary vesicostomy was placed to provide adequate drainage in the presence of urethral stenosis. The patient developed a single episode of pyelonephritis within the first six months post-operatively, but there were no other urologic complications. At 13 months, the renal function is excellent with a mean glomerular filtration rate of 100 mL/min/1.73 m(2) and no clinical evidence of rejection. This case demonstrates that simultaneous UC and KT can be safely performed even in infants with non-compliant bladders and renal failure.
