Progression of diabetic nephropathy from the stage of macroproteinuria with near-normal renal function until start of dialysis was compared in 16 patients with type I and 16 patients with type II diabetes mellitus. The mean creatinine clearance at the beginning of the study was 89 +/- 13 ml/min/1.73 m2 in patients with type I and 81 +/- 6 ml/min/1.73 m2 in those with type II diabetes. Dialysis was started after a mean interval of 77 (44-133) months, when creatinine clearance had decreased to 8 +/- 2 ml/min/1.73 m2 in type I diabetic patients. The respective figures for type II diabetic patients were 81 (40-124) months and 7 +/- 2 ml/min/1.73 m2. The mean rate of decrease in creatinine clearance was 1.05 +/- 0.45 ml/min/month in type I and 0.91 +/- 0.41 ml/min/month in type II diabetes. The mean rate of decrease was 1.46 +/- 0.30 ml/min/month in type I diabetic patients with a systolic BP > 160 mmHg versus 0.80 +/- 0.42 ml/min/month with < 160 mmHg (P < 0.01). In the type II diabetics the respective figures were 1.38 +/- 0.40 ml/min/month versus 0.78 +/- 0.15 ml/min/month (P < 0.01). During the observation period the prevalence of coronary heart disease increased from 6 to 50% in type I and from 31 to 87% in type II diabetes. In conclusion, the rate of progression of diabetic nephropathy during the predialytic phase is similar in type I and type II diabetes; BP adversely affects the rate of progression to the same extent in both groups.
Simultaneous pancreas-kidney transplantation (SPKT) has become the therapy of choice in patients with Type I (insulin-dependent) diabetes mellitus who have end-stage renal disease. During the last decade graft and patient survival have been improved, the 1-year pancreas graft survival rate is currently at 81 % for SPKT [1].Several studies have shown that diabetic retinopathy and peripheral neuropathy are positively influenced by pancreas transplantation [2,3]. A recent study also showed that pancreas transplantation in non-uraemic patients can reverse lesions of diabetic nephropathy, but this is not seen before 5 years of normoglycaemia [4]. Diabetologia (2000) Abstract Aims/hypothesis. The aim of the study was to examine the effect of pancreas-kidney transplantation on the progression of macrovascular diseases in Type I diabetic patients with end-stage renal disease.Methods. The progression of cerebrovascular disease, coronary heart disease and peripheral vascular disease in uraemic patients with Type I (insulin-dependent) diabetes mellitus and who had had simultaneous pancreas-kidney transplantation was compared with that of recipients of a kidney transplant alone. Between 1986 and 1998 a total of 11 uraemic diabetic patients received a simultaneous pancreaskidney transplantation and 10 diabetic patients a kidney transplant alone. All transplants functioned for at least 24 months, the mean observation period was 69 ± 37 compared with 70 ± 33 months in both patient groups. Macroangiopathic diseases were classified in four stages as described earlier.Results. In the group with simultaneous pancreas-kidney transplantation progression of cerebrovascular and coronary heart disease was observed in four patients (36 %) and progression of peripheral vascular disease in five subjects (45 %). In the cohort with kidney transplant alone four patients (40 %) showed progression of cerebrovascular and coronary heart disease and five progression of peripheral vascular disease (50 %); the difference is not significant. Mean values of HbA 1 c (5.8 ± 0.2 vs 7.5 ± 0.6 %, p < 0.001) and serum triglycerides (1.2 ± 0.4 vs 2.0 ± 1.0 mmol/l, p < 0.05) were significantly lower in the patients with pancreas-kidney transplantation than in the patient group with kidney transplant alone. Serum cholesterol concentrations and blood pressures were similar in both cohorts. Conclusion/interpretation. From our results we concluded that pancreas-kidney transplantation reduces risk factors for the development of macroangiopathy but fails to halt progression of macrovascular diseases similar to Type I diabetic patients with kidney transplant alone.

We report on a Mycobacterium marinum infection in a diabetic woman 8 years after undergoing a combined pancreas-kidney transplantation. This is, to our knowledge, the first case report on an isolated skin infection with atypical mycobacteria after simultaneous pancreas-kidney transplantation. A genetic probe categorization revealed an infection with M. marinum. Skin tuberculosis caused by M. marinum is an uncommon complication in kidney or pancreas-kidney transplant recipients, hence the diagnosis can be delayed.
