End-stage renal disease (ESRD), due to its high morbidity and mortality as well as social and financial implications, is a major public health problem. Outcome depends not only on different modalities of treatment like hemodialysis and peritoneal dialysis, but also on existing co-morbidities, age, duration on dialysis, supportive therapies and infection control strategies. Thus, a detailed study becomes necessary to improve health care delivery, provide medical care and to establish a geographical reference. The present study was undertaken to characterize the ESRD patients by their demographic and co-morbid conditions and relate this to the morbidity and mortality trends. The medical records of 110 ESRD patients seen over a five-year period (June 1995 to December 1999) in two tertiary-care hospitals in Riyadh, Saudi Arabia were studied retrospectively. There were 79 (64.5%) males and 31 (35.5%) females; their age ranged from 17 to 92 years (mean age 53.8 +/- 17.8 years). Diabetes was the commonest cause of ESRD seen in 26 (26.6%) followed by nephrosclerosis, unknown etiology, lupus nephritis, pyelonephritis and primary glomerulonephritis. Diabetes mellitus was the most prevalent co-morbidity seen during the study period and occurred in 65 patients (59%) followed by heart disease in 36 (32.7%), liver disease in 30 (27.3%), cerebrovascular accidents in 13 (11.8%) and neoplasm in 11 (10%). Seven (6.3%) patients only were smokers. Hemodialysis was the most frequent treatment choice as renal replacement therapy. Among the causes of hospitalization, cardiovascular conditions were the leading single cause (19.1%), followed by access related reasons and infections (11.5% each). The overall hospitalization rate was 11.2 days/year. The overall mortality rate was 8.07 deaths/year. The leading cause of death was cardiovascular in 15 (51.7%) followed by unknown/sudden death in eight (27.5%). Other causes of death included fluid overload, gastrointestinal hemorrhage, septicemia, liver disease and pulmonary embolism. Diabetes was the commonest co-morbid cause among the deceased. Old age, diabetes mellitus, prolonged duration on dialysis and cardiac diseases were the common causes of mortality. Our findings are consistent with worldwide reports. The study provides a reference data and will hopefully be helpful in improving the medical care.

By using kerosene and avoiding postmortem rigor one can obtain perfusion rates in kidneys nearly five times faster than those reported by observers who perfused kidneys immediately post mortem with saline solution, only half as viscous as kerosene. The results obtained by kerosene perfusion indicate possible renal blood flow 50 to 100 per cent greater than that measured by Smith and his coworkers (7) in living men by diodrast clearance under normal conditions, and about as high as those observed in febrile subjects. Like the diodrast method, kerosene perfusion shows a striking decrease in renal vascular bed between early matuity (age 18 to 35) and senescence (45 to 60). This decrease is about 25 per cent. Most kidneys from patients with hypertension without uremia have vascular beds in the normal range, but a few show great decreases in capacity for blood flow. This evidence is interpreted as another indication that renal arteriosclerosis is often a result, rarely a cause of hypertension. Significant occlusion of large renal arteries is rare. Uremia due to amyloid may occur with no significant decrease in renal vascular bed, but the uremia of renal sclerosis, glomerulo- or pyelonephritis is associated with reduction of vascular bed to very low levels.

Urinary lactic dehydrogenase, alkaline phosphatase and lysozyme determinations were performed on 70 patients with various kidney diseases such as acute and chronic pyelonephritis, acute and chronic glomerulonephritis, idiopathic nephrotic syndrome, diabetic nephropathy, nephrosclerosis, lupus nephritis, analgesic nephropathy, gouty nephropathy, renal tuberculosis, renal lithiasis, and polycystic kidneys. Fifty-three of these patients had elevated levels of urinary lactic dehydrogenase, but this was not of any value in determining the etiology of the renal disease. Similarly, the elevation of alkaline phosphatase in 23 of the 70 had no etiological significance. Neither of these determinations was significant in indicating the degree of renal functional impairment or prognosis. The urinary lysozyme was significantly elevated in only five of the 70 patients and was of no value in indicating the presence or the seriousness of the underlying renal disease.
