Diabetic gangrene in black patients
Southern Medical Journal
|March 1, 1982
Summary
Hypertension is strongly linked to advanced lower limb vascular disease and amputations in Black Americans with diabetic gangrene. Anemia also correlates with higher amputation rates and mortality in these patients.
Area of Science:
- Vascular Surgery
- Diabetology
- Epidemiology
Background:
- Diabetic gangrene affects a significant portion of the diabetic population.
- Understanding risk factors for severe outcomes like amputation is crucial.
Purpose of the Study:
- To investigate the clinical features and risk factors associated with diabetic gangrene in American Black patients.
- To identify associations between hypertension, anemia, and amputation levels or mortality.
Main Methods:
- Retrospective review of 104 American Black patients with diabetic gangrene.
- Analysis of clinical features, comorbidities (hypertension, cardiac disease), anemia status, and amputation levels.
- Statistical analysis to determine significant associations (P-values provided).
Main Results:
- Clinical features were similar to the general diabetic population.
- Hypertension significantly associated with above-knee and bilateral amputations (P < .001, P < .01).
- Anemia (hematocrit 20-30%) significantly associated with above-knee amputation and mortality (P < .02, P < .05).
- Higher mortality in patients with cardiac disease, above-knee amputations, and longer diabetes duration (P < .02, P < .01, P < .025).
Conclusions:
- Hypertension is a strong indicator of advanced occlusive vascular disease in the lower limbs of diabetic patients.
- Anemia is a significant risk factor for amputation and mortality in diabetic gangrene.
- Effective management of hypertension and anemia is vital in preventing severe outcomes in diabetic patients.

01:26Type I Diabetes II: Pathophysiology
Type 1 diabetes mellitus arises from an immune-mediated destruction of pancreatic β-cells, resulting in an absolute deficiency of insulin. This process develops in genetically susceptible individuals when autoimmunity, environmental exposures, and immunologic dysregulation converge to trigger a targeted attack on the insulin-producing cells of the pancreas. The β-cells are located within the islets of Langerhans and are essential for regulating blood glucose by facilitating cellular uptake of...
01:22Complications of Diabetes Mellitus
Diabetes mellitus is a chronic metabolic disorder characterized by persistent hyperglycemia due to insulin deficiency, resistance, or both. Prolonged hyperglycemia disrupts metabolic homeostasis and leads to acute and chronic complications.Acute ComplicationsAcute complications result from sudden metabolic imbalance.Diabetic ketoacidosis (DKA) mainly appears in type 1 diabetes but may also develop in type 2 diabetes, particularly under extreme stress. It arises from severe insulin deficiency,...
01:31Diabetic Foot Ulcer
Definition A diabetic foot ulcer (DFU) is a chronic, non-healing wound that develops in individuals with diabetes. It typically occurs on pressure-bearing areas such as the heel, metatarsal heads, or hallux, and carries a high risk of infection and amputation.Pathophysiology • The development of DFUs can be explained by four interconnected mechanisms: neuropathy, ischemia, infection, and impaired wound healing. • Neuropathy is the most common factor. Sensory neuropathy reduces pain perception,...
01:27Diabetic Retinopathy
DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
01:28Diabetic Nephropathy
Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...
01:22Diabetic Neuropathy
DefinitionDiabetic neuropathy is nerve damage caused by long-standing diabetes mellitus. It results directly from prolonged high blood sugar levels.PathophysiologyThe pathophysiology of diabetic neuropathy involves both metabolic and vascular disturbances triggered by chronic hyperglycemia.Metabolic injury: Elevated glucose levels activate the polyol pathway within nerve cells, leading to the accumulation of sorbitol and fructose. This increases oxidative stress, disrupts normal nerve...
