ABSTRACT
OBJECTIVE: To know the prevalence of hyperglycemia in patients with Spanish toxic oil syndrome (TOS). To analyze clinical, biochemical, and pathological associated factors. To compare them with a control group. DESIGN: Case and controls study. SETTING: Primary Health Care. XI Sanitary district in Madrid. PATIENTS AND OTHER PARTICIPANTS: 734 cases with toxic oil syndrome. 1474 control subjects. MEASUREMENTS AND MAIN RESULTS: Prevalence of impaired glucose tolerance was 2.95% in TOS and 0.07% in control subjects (p < 0.001; OR, 7.55; IC, 291-19.57). Diabetes No insulin treated was 7.78% in TOS and 3.26% in controls (p < 0.001; OR 250; IC 1.62-3.87). Diabetes insulin treated was 1.99% in TOS and 0.47% in controls (p < 0.01; OR, 4.98; IC, 1.80-13.78). Prevalence of diabetes mellitus in TOS was 9.77 and 3.67% (p < 0.001; OR, 2.85; IC, 1.90-4.25) in controls. The pancreatic lesions found in the necropsies were vasculitis type TOS (4 cases) and endothelial vascular lesions (1 case). CONCLUSIONS: The prevalence of hyperglycemia in TOS reached 13%, where as in the control subjects, it was 3.8% (p < 0.001). The pancreatic lesions detected in deceased TOS patients did not coincide with those commonly described in diabetes mellitus.
