The aim of the present work is to evaluate the function of the proximal tubule in patients with active metabolic stone disease (a.m.s.d.), recognizing the urinary excretion of beta-2-microglobulin (B2-M) as a sensitive marker of that function. The investigated group included 30 patients with a.m.s.d. accompanied by chronic pyelonephritis (CP) and 31 patients with a.m.s.d. without CP. The serum and urinary B2-M concentrations were estimated by radioimmunoassay. The clearance of B2-M (CB2-M) and the tubular reabsorption of B2-M (TRB2-M) were estimated. Patients with a.m.s.d. and CP showed an increased excretion of B2-M, significantly higher values of CB2-M and a significantly lower TRB2-M. The results indicate that the proximal tubular dysfunction in the group of patients with a.m.s.d. is a result of a chronic inflammatory process in the urinary tract.

D007687	Kidney Tubules, Proximal	The renal tubule portion that extends from the BOWMAN CAPSULE in the KIDNEY CORTEX into the KIDNEY MEDULLA. The proximal tubule consists of a convoluted proximal segment in the cortex, and a distal straight segment descending into the medulla where it forms the U-shaped LOOP OF HENLE.

It can be congenital due to inherited enzyme abnormality (METABOLISM, INBORN ERRORS) or acquired due to disease of an endocrine organ or failure of a metabolically important organ such as the liver.

D002908	Chronic Disease	Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed). For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).
