[Diabetes mellitus and the biosynthesis of porphyrins]. 1983

M P Pisanets, and K Pavlov

The blood and urine porphyrin content and porphyrin biosynthesis in the red blood cells after delta-amino levulinic acid (ALA) incubation, porphobilinogen and non-consumed ALA levels, porphobilinogen-synthetase activity were studied in 86 patients divided into 3 groups depending on diabetes severity. Porphyrin separation was investigated by means of thin-layer chromatography. It was found that porphyrin biosynthesis decreases in all diabetics at the early periods of the disease, not depending on its severity. Porphyrin biosynthesis is lowered during a phase of chronic renal insufficiency in patients with diabetic nephropathy. Porphyrin metabolic disorder is caused by hepatic dysfunction and diabetic nephropathy development.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D008930	Mitochondria, Liver	Mitochondria in hepatocytes. As in all mitochondria, there are an outer membrane and an inner membrane, together creating two separate mitochondrial compartments: the internal matrix space and a much narrower intermembrane space. In the liver mitochondrion, an estimated 67% of the total mitochondrial proteins is located in the matrix.

D011166	Porphyrins	A group of compounds containing the porphin structure, four pyrrole rings connected by methine bridges in a cyclic configuration to which a variety of side chains are attached. The nature of the side chain is indicated by a prefix, as uroporphyrin, hematoporphyrin, etc. The porphyrins, in combination with iron, form the heme component in biologically significant compounds such as hemoglobin and myoglobin.	Porphyrin
D011704	Pyelonephritis	Inflammation of the KIDNEY involving the renal parenchyma (the NEPHRONS); KIDNEY PELVIS; and KIDNEY CALICES. It is characterized by ABDOMINAL PAIN; FEVER; NAUSEA; VOMITING; and occasionally DIARRHEA.	Necrotizing Pyelonephritis,Pyelonephritis, Acute Necrotizing,Pyelonephritides
D003920	Diabetes Mellitus	A heterogeneous group of disorders characterized by HYPERGLYCEMIA and GLUCOSE INTOLERANCE.
D003928	Diabetic Nephropathies	KIDNEY injuries associated with diabetes mellitus and affecting KIDNEY GLOMERULUS; ARTERIOLES; KIDNEY TUBULES; and the interstitium. Clinical signs include persistent PROTEINURIA, from microalbuminuria progressing to ALBUMINURIA of greater than 300 mg/24 h, leading to reduced GLOMERULAR FILTRATION RATE and END-STAGE RENAL DISEASE.
