Individuals with cystic fibrosis have a 1% to 7% incidence of insulin-dependent diabetes mellitus. The occurrence of diabetic microangiopathy in patients with cystic fibrosis has been reported recently. From 1978 to 1987, 19 patients with cystic fibrosis and diabetes mellitus were followed up. Four patients (21%) had evidence of diabetic microangiopathy. In one, peripheral neuropathy developed 5 years after the onset of diabetes mellitus, and the other 3 patients each had complications of retinopathy, nephropathy, and neuropathy which developed 10 years after the onset of diabetes mellitus. All were poorly compliant in their medical care. Significant morbidity was seen in the 3 patients with multisystem involvement--blindness, glaucoma, hypertension, and renal failure. The combination of long-standing diabetes mellitus, poor glycemic control, plus pathophysiologic features associated with cystic fibrosis may have contributed to the development of microangiopathy. The use of steroids in 4 other patients and dextrose infusions (as part of hyperalimentation) in another 4 patients precipitated or exacerbated diabetes. The data indicate that diabetic microangiopathy can occur in the individual with cystic fibrosis. Routine screening for diabetes and its complications in the population with cystic fibrosis, as well as optimal control of hyperglycemia, is warranted.

A 54-year-old woman, with no previously documented thyroid disease, treated with amiodarone (200 mg/day, five days a week for 33 months) for paroxysmal tachyarrhythmia complicating mitral stenosis, suddenly developed extremely severe thyrotoxicosis. After therapeutic failures with carbimazole and propylthyrouracil (PTU) associated with beta-blockers, she was transferred to intensive care for plasma exchange (PE). Two PE were performed, temporarily aggravating the cardiovascular status of the patient, with no secondary improvement. The quantity of T3 removed was very small, about 1,000 ng per exchange. On the 14th day PTU had to be discontinued (toxic thrombopenia) and only symptomatic treatment was maintained (assisted ventilation, digitalis, hyperalimentation). In the 4th month, while the patient had a high total serum iodine, hypothyroidism developed due to partial block of the organification of the iodine with high TSH and fixation; this state also lasted 4 months. Spontaneous recovery was observed after 8 months. In addition a severe peripheral neuropathy was observed during the hyperthyroid phase confirmed by electromyography, distinct from the signs of thyrotoxic myopathy. This gradually regressed over 7 months and may be attributed to amiodarone therapy. The association of these two successive types of thyroid disorder due to amiodarone is an exceptionally rare phenomenon. Severe thyrotoxicosis generally requires long-term symptomatic therapy, its natural course being towards spontaneous regression. PE are ineffective on the circulating hormonal levels and were dangerous because of the underlying cardiac disease. The development of hypothyroidism at the 4th month is explained by the persistent iodine overload, and therefore prolonged surveillance after withdrawal of therapy is advised. The neurological complication of amiodarone was quite distinct from the hyperthyroid myopathy.

India is amidst a demographic transition showing an ageing trend. This will increase non-communicable diseases including diabetes which is already showing an increasing trend. With scanty literature existing on elderly diabetics (> 60 years of age), it was decided to study the clinico-laboratory and complication profile of this group of patients. Fifty consecutive elderly diabetics were studied and evaluated for ECG, chest x-ray, blood sugar, urea, creatinine, lipid profile, proteinuria, motor nerve conduction velocity and autonomic neuropathy. Duration of diabetes varied from one month to 28 years. Fifty-six per cent of the patients presented with classical symptoms of polyuria, polyphagia and polydipsia. Hypertension was present in 40% and cataract in 54% of the patients. Eighteen per cent were obese, 52% had evidence of peripheral neuropathy while 56% had autonomic neuropathy. Background diabetic retinopathy was present in 56%, pre-proliferative retinopathy and maculopathy in 4% each; hypertensive retinopathy in 10% of patients; 44% had microproteinuria and 8% had chronic renal failure. Hypercholesterolaemia was present in 64% and hypertriglyceridaemia in 42% of the patients with 26% having coronary artery disease. Sixty per cent were harbouring infections--20% had foot infections, 14% had tuberculosis and 10% had urinary tract infections. Ninety-two per cent of the patients were aware of their disease but 62% were not aware of the complications and of the need for strict dietary and drug compliance. There was a high prevalence of associated diseases viz, osteoarthritis, cataract, hypertension, hepatitis and parkinsonism. Therefore, this study brings out the need to have a holistic and multidisciplinary approach for management of elderly diabetics who constitute a heterogeneous group with distinct health care problems.
