- Nefropatia diabética: protocolo de estudo pré-transplantação renalPublication . Baptista, C; Bastos, M; Paiva, S; Martins, T; Leitão, P; Lemos, MC; Alves, R; Bastos, C; Mota, A; Carvalheiro, M; Furtado, AL; Ruas, ABetween May 1990 and October 1998, 67 diabetic patients with end-stage renal disease, on dialysis, were submitted to a standardized protocol in order to assess the coexistence and degree of other diabetic and nondiabetic complications that could affect transplantation. Some of the results were analysed. Type 2 diabetic patients had more abnormal results on the lower limbs doppler ultrasound and on the lower limbs arteriography than type 1 (p < 0.05). Type 2 diabetic patients had more cardiovascular complications so the decision to transplant should be taken on a case by case basis.
- Sources of hepatic glucose production by 2H2O ingestion and Bayesian analysis of 2H glucuronide enrichment.Publication . Delgado, TC; Barosa, C; Castro, MM; Geraldes, CF; Bastos, M; Baptista, C; Fagulha, A; Barros, L; Mota, A; Carvalheiro, M; Jones, JG; Merrit, MThe contribution of gluconeogenesis to hepatic glucose production (GP) was quantified after (2)H(2)O ingestion by Bayesian analysis of the position 2 and 5 (2)H-NMR signals (H2 and H5) of monoacetone glucose (MAG) derived from urinary acetaminophen glucuronide. Six controls and 10 kidney transplant (KTx) patients with cyclosporine A (CsA) immunosuppressant therapy were studied. Seven KTx patients were lean and euglycemic (BMI = 24.3 +/- 1.0 kg/m(2); fasting glucose = 4.7 +/- 0.1 mM) while three were obese and hyperglycemic (BMI = 30.5 +/- 0.7 kg/m(2); fasting glucose = 7.1 +/- 0.5 mM). For the 16 spectra analyzed, the mean coefficient of variation for the gluconeogenesis contribution was 10% +/- 5%. This uncertainty was associated with a mean signal-to-noise ratio (SNR) of 79:1 and 45:1 for the MAG H2 and H5 signals, respectively. For control subjects, gluconeogenesis contributed 54% +/- 7% of GP as determined by the mean and standard deviation (SD) of individual Bayesian analyses. For the lean/normoglycemic KTx subjects, the gluconeogenic contribution to GP was 62% +/- 7% (P = 0.06 vs. controls), while hyperglycemic/obese KTx patients had a gluconeogenic contribution of 68% +/- 3% (P < 0.005 vs. controls). These data suggest that in KTx patients, an increased gluconeogenic contribution to GP is strongly associated with obesity and hyperglycemia
- Transplantação pancreáticaPublication . Bastos, M; Campos, MV; Baptista, C; Alves, R; Bastos, C; Mota, A; Carvalheiro, M; Furtado, AL; Ruas, AA clinic case of simultaneous pancreas/kidney transplantation on a type 1 diabetic patient is described. A six years follow-up was made with both organs functionating and a good quality of live.Then the authors make a review of the available surgical techniques, indications and complications of this form of treatment. A comparison between the Portuguese and the International experience was discussed.
- Transplantação renal em doentes com diabetes mellitus tipo I e tipo IIPublication . Baptista, C; Bastos, M; Gomes, L; Macário, F; Ruas, L; Rodrigues, D; Alves, R; Gomes, H; Ferreira, C; Roseiro, A; Paiva, S; Barros, L; Carvalheiro, M; Mota, A; Furtado, AL; Ruas, AA total of 618 patients with end-stage renal disease received kidney transplants between 1980 and September 1996. Twenty eight of them were diabetics. Better results were achieved for type 1 diabetic patients than for type 2 (mortality: 5.9% vs 27.3%; functioning graft: 88.2% vs 72.7%). The morbility was also higher in those patients (infections: 81.8% vs 29.4%; vascular complications: 45.5% vs 17.6%). Actuarial patient and graft survival were lower for type 2 than for non diabetic patients. For type 1 diabetics the results are similar to those for non diabetics. Better results can probably be achieved by restricting the selection criteria. The decision to transplant or maintain on dialysis should be made on a case by case basis.
