Serum lipids were estimated in patients with renal amyloidosis (RA): 21 with familial Mediterranean fever (FMF) and 24 with secondary renal amyloidosis versus FMF patients without renal dysfunction or having chronic glomerular nephritis. All the RA patients had dyslipidemia of atherogenic nature the severity of which correlated with that of renal disorder. Our results showed the presence of dyslipidemia early during RA course. It is renal involvement that results in dyslipidemia observed in FMF patients.

The study involved 33 patients with chronic glomerulonephritis of hypertonic type (CGNHT), in their number 8 with the signs of a moderate renal failure, 25 with a latent form of the disease (CGNLF), 10 ones with hypertension, and 20 healthy age-matched subjects. Patients with CGNHT and hypertension patients were comparatively studies for the blood pressure values. Fatty acid, glycerine, malonic dialdehyde contents were investigated in all the examinees. Some patients were studied for the fraction composition of fatty acids as well. The majority of CGNHT and hypertensive patients demonstrated a significant increase in the levels of fatty acids, glycerine and malonic dialdehyde versus healthy and CGNLF subjects, whereas the content of polyunsaturated fatty acids was found to be decreased (exemplified by linoleic acid) and the content of monounsaturated ones increased (exemplified by myristic acid). The aforementioned changes were mostly pronounced in those CGNHT patients who had higher systolic pressure whereas the signs of renal failure were of no importance for the value variance. No differences were revealed in the parameters of hypertensive and CGNHT patients. Accounting for the role of fatty acids, polyunsaturated ones predominantly, which provide the energy consumption of myocardium (raised in those with higher blood pressure values) the authors suggested that arterial hypertension played a definite role in the aforementioned alterations. The results obtained could be of a certain clinical value for dietetic and medicamentous improvement of the deficiency in the levels of polyunsaturated fatty acids in the patients with CGNHT, possible normalization of fatty acid content and composition during the decrease of the blood pressure.
