- In a cross-sectional study of diabetic patients diagnosed at or after 30 years, and with different stages of retinopathy, factors such as duration of diabetes, treatment mode, metabolic control, blood pressure, and clinical signs of nephropathy were examined. The different stages of retinopathy used were absence of retinopathy, simplex, and severe retinopathy. Patients with simplex and severe retinopathy were older than those without retinopathy (p less than 0.001, and p less than 0.01, respectively). They also had a longer duration of diabetes (p less than 0.001), and were more often treated with insulin (p less than 0.001) and in larger doses (p less than 0.001). Their glycosylated haemoglobin levels were higher (p less than 0.01). Their systolic blood pressure was higher (p less than 0.01), but the diastolic blood pressure did not differ, and the number of patients treated for hypertension was similar in all groups. Albumin clearance was higher (p less than 0.01 and p less than 0.001), as were urinary albumin levels (p less than 0.001). The only variables that distinguished patients with simplex from those with severe retinopathy were albumin clearance (p less than 0.01) and urinary albumin levels (p less than 0.05).

Retinopathy and nephropathy in insulin-dependent diabetics: an inconsistent relationship?
- 1987
-
Ingår i: Diabetic Medicine. - 1464-5491. ; 4:3, s. 248-250
-
Tidskriftsartikel (refereegranskat)abstract
- The association between retinopathy and nephropathy was investigated in a retrospective study of 52 insulin-dependent diabetics with preproliferative or proliferative retinopathy and in 48 patients without or with background retinopathy. The duration of diabetes was 23.2 +/- 1.0 years (mean +/- SEM) and 22.0 +/- 1.2 years in the two groups. Patients in the retinopathy group showed a higher frequency of detectable nephropathy and were more often treated with antihypertensive drugs. However, a high proportion (35%) of patients with proliferative retinopathy did not show any detectable signs of nephropathy. Furthermore, nephropathy did not seem to develop in patients with retinopathy during an observation period of up to 9 years. The data suggest that the factors underlying the development of retinal and renal microangiopathy might be of different origin.

Wound classification is more important than site of ulceration in the outcome of diabetic foot ulcers
- 1989

Ingår i: Diabetic Medicine. - 1464-5491. ; 6:6, s. 526-530
-
Tidskriftsartikel (refereegranskat)abstract
- The importance of wound classification and site of ulceration was evaluated in 314 consecutive diabetic patients with foot ulcers. The ulcers were classified as superficial (through the full thickness of the dermis; n = 150), deep (n = 50), osteomyelitis and/or abscess (n = 46), minor gangrene (n = 39) or major gangrene (n = 29). Wound healing was defined as intact skin for at least 6 months. In patients with superficial and deep ulcers, primary healing occurred in 88% and 78%, respectively, compared with 57% in those patient who developed an abscess and/or osteomyelitis. Only 2 out of 68 patients with gangrene healed (through mummification) without amputation. Patients with gangrene had lower ankle and toe blood pressure than patients with all other types of ulcers. There were only marginal differences in primary healing rate between different ulcer sites. The highest rate was seen in ulcers localized to the metatarsal heads (78%). Patients with multiple ulcers had the lowest primary healing rate (5%) compared with single ulcers at all sites. These differences were probably due to circulatory factors, since patients with multiple ulcers had lower distal perfusion pressures compared with all other groups.
