[Renal transplantation in patients with neurogenic bladder].

BACKGROUND: Renal transplantation can be done in patients with neurogenic bladder and clean intermittent self catheterization maintains renal function AIM: To retrospective assess the results of renal transplantation in patients with neurogenic bladder. PATIENTS AND METHODS: The medical records of seven patients aged 10 to 22 years old (3 female) followed during 7 to 32 months were reviewed. All patients had urinary tract infection, prior to transplantation, were instructed on self catheterization and received tri-associated immunosuppression. RESULTS: Grafts came from alive related donors in 5 patients and from cadavers in two. Prior to transplantation, three patients were subjected to nephrectomy and three to bladder enlargement, leaving a pigtail catheter. After transplantation, one lymphocele was drained, one uretherostomy due to an impacted lithiasis and one nephrectomy plus vesical enlargement due to intravesical pressures over 40 cm H2O, were done. One uretheral stricture was treated with dilatation. Seven episodes of pyelonephritis, 19 urinary tract infections and 77 asymptomatic bacteriurias were documented. Serum creatinine at the end of follow up ranged from 0.7 to 2.1 mg/dl. There were 0.7 acute rejection episodes per patient and all grafts survived. CONCLUSIONS: Renal transplantation in patients with neurogenic bladder is feasible, performing a vesical enlargement. There is however a high frequency of infectious episodes.

[Nail-patella syndrome associated with monoclonal gammopathy. Review regarding a case].

A 54 years old female with significant impairment of renal function is presented. On physical examination, the presence of dystrophic nails, elbow dysplasia and prominent iliac horns. Familial study showed similar nail and bone deformities in 3 of six sons. The nail patella syndrome diagnosis was based on these findings. This is a rare autosomal dominant hereditary disease, probably related to congenital alterations in collagen metabolism. Clinical characteristics include bone abnormalities that principally involve knees and elbows, nail alterations and the presence of iliac horns, that are considered pathognomonic of the syndrome. Renal involvement is observed in 30 to 55% of cases. This patient had also an IgA-lambda paraprotein, whose relationship to the above mentioned syndrome is uncertain, since no evidences of malignant plasma cell dyscrasia were demonstrated.

[Pregnancy in a class-T diabetic patient].

We report the pregnancy of a 35 year old diabetic woman with a positive Australia antigen, 3 years after a successful cadaver kidney transplant. Immunosuppressive therapy with prednisone, azathioprine and cyclosporine was maintained. Pregnancy was complicated by an acute rejection episode on week 13, mild hypertension and intrahepatic cholestasis on week 22. Cesarean section and tubal ligation were performed at 32 and a half weeks. A 2020 g female infant was delivered, with Apgar scores of 8 and 9 at 1 and 5 min, respectively. Mild respiratory distress, jaundice and hypocalcemia were noted. The Australia antigen was negative. No fetal anomalies were detected. The high risk of pregnancy in a class T diabetic patient is confirmed in this case.

A prospective one-year study evaluating the clinical outcome of recipients of living donor kidneys treated with cyclosporin and azathioprine.

Thirty recipients of living related donor kidneys treated either with cyclosporin or azathioprine were evaluated clinically and functionally in a 1-year prospective study. Only the azathioprine group showed either accelerated or chronic rejection (one patient each). The azathioprine patients had higher rate of infectious episodes (P = 0.05), leukopenia (P = 0.003) and steroidal side-effects (P less than 0.007). During the early post-transplant period the renal functional performance was the same in both groups. Afterwards, however, the plasma creatinine was higher in the cyclosporin group (P less than 0.01). Mean arterial pressure remained similar throughout the study in both groups. The anaemia correction was similar in both groups but the haematocrit was greater in the cyclosporin-treated subjects (P less than 0.005).

[Parasitic infections in renal transplantation patients].

We performed indirect hemagglutination tests for toxoplasmosis and Chagas disease, complement fixation test for toxoplasmosis, stool examination for parasites and Graham test for enteroparasites in 51 patients before and after renal transplant. Post transplant surveys were performed at 3, 6, 9, 12 and 18 months. 18 patients who were positive for toxoplasmosis remained so and 5 new asymptomatic cases were detected in the post transplant period (15%). Two patients who were positive for Chagas disease remained positive and asymptomatic. One patient receiving a kidney from a Chagas positive donor remains negative. Asymptomatic enteric infection was detected in 45% of patients at some time during follow up: amebic infection (25%), giardiasis (14%) and oxyuriasis (24%). Two patients showed asymptomatic cryptosporidiasis.
