Renal replacement therapy (RRT) for Brazilian children with uraemia has been utilized since 1970 in the state of Rio Grande do Sul. One hundred and eighty patients receiving this therapy between 1970 and 1988 have been reviewed. The annual acceptance rate of new paediatric patients in this period increased from 0.6 to 6.5 patients per million child population. Glomerulonephritis (36.1%) and pyelonephritis including urological anomalies (31.7%) were the most frequent causes of end-stage renal disease. Outpatient hospital haemodialysis was the primary form of dialytic treatment in patients 5-15 years of age. Continuous ambulatory peritoneal dialysis was more often used in patients less than 5 years of age. The survival after 1 year on dialysis was 79.9% for children aged 5-15 years starting dialysis during the period 1985-1988. Fluid overload with congestive heart failure and infection were the main causes of death in children on dialysis. Eighty-four children received 93 grafts; only 14 (15%) were from cadaveric donors. One-year patient and graft survival of first living-related donor transplants were 92.2% and 78.5% respectively during the period 1985-1988. Infection accounted for 43.5% of deaths after transplantation. We conclude that RRT is becoming increasingly successful for children in our region but that greater emphasis upon patient compliance with all forms of RRT and upon cadaver kidney donation is needed.

The development of pulmonary injury in cases of antepartum pyelonephritis is rare but serious. To date, factors that might identify patients at risk have not been determined. We compared 11 patients with pyelonephritis and pulmonary injury with 119 patients with pyelonephritis only. Pulmonary injury was more likely to occur in the more severe cases; however, the presence of a maternal heart rate greater than 110 beats/min and a fever to 103 degrees F 12 to 24 hours before the occurrence of respiratory symptoms in a gestation greater than 20 weeks was highly predictive of pulmonary injury. The most significant predictive factors associated with pulmonary injury were elements of treatment such as fluid overload, use of tocolytic agents, and, to a lesser extent, choice of antibiotic. Therefore, if tocolytic agents are considered at all in the management of acute pyelonephritis in pregnancy, they should be used only in patients with documented cervical change. In addition, urinary output should be monitored very closely. These data also may suggest a cause of the pulmonary edema that is occasionally seen in the management of premature labor with the use of tocolytic agents and fluids in the presence of a possible occult infection.

Patients with pyelonephritic renal scarring are at risk of developing renal failure and hypertension. We studied glomerular filtration rate (GFR), renal plasma flow (RPF), filtration fraction (FF), systolic (SBP) and diastolic (DBP) blood pressure, fractional sodium, potassium and phosphate excretion, peripheral renin activity (PRA), plasma aldosterone (p-Aldo), urinary albumin excretion (U-Alb) and urinary beta 2-microglobulin excretion (beta 2-M) in hydropenia and during transition to 3% volume expansion with isotonic saline infusion in 22 female patients with renal scarring due to pyelonephritis and 9 healthy controls. The patients had significantly lower GFR, higher SBP and higher PRA in hydropenia, but there was no significant difference in RPF, FF, DBP or p-Aldo. After volume expansion, SBP, DBP, PRA and p-Aldo were significantly higher in patients than in controls. Transition to 3% volume expansion was associated with a similar increase in SBP in both patients and controls, whereas DBP increased significantly more in the patients (p less than 0.01). Volume expansion resulted in a significant suppression of PRA and p-Aldo in both patients and controls. The patients with renal scarring had the same capacity to excrete sodium and water during transition to volume expansion as the healthy controls. The renin-aldosterone system seems abnormally activated and is probably more important than hypervolemia in the development of hypertension in this group of patients.

At the end of 1985 there were 5482 patients known to the Registry who started renal replacement therapy (RRT) between the ages of 6 months and 15 years. Of these, approximately 25% had died, 30% were still aged less than 15 years, and the other 45% were older. The acceptance rate of new patients over the last 10 years has slowly but steadily increased; six new paediatric patients per million child population probably represents the likely needs of the near future. Hospital haemodialysis remained the main form of renal replacement therapy in new patients, while 3 years after start of RRT, transplantation became the most frequently used replacement therapy; CAPD appeared to be used mainly in children with a short waiting time for transplantation. Out of the 384 grafts reported in 1985, only 16% were from living related donors; among 321 cadaver grafts, 24% were second and only 3% were third grafts. Glomerulonephritis and pyelonephritis accounted for 50% of all primary renal diseases. During the last 5 years, the proportion with glomerulonephritis seems to have decreased slightly. Hyperkalaemia and fluid overload have still to be considered the main causes of death. Only in 17% of all cases was the cause of death reported as unknown or undetermined.

Over a 7-year period, 15 pregnant women admitted to Parkland Memorial Hospital for acute pyelonephritis developed respiratory insufficiency characterized by dyspnea, tachypnea, hypoxemia, and radiographic evidence of pulmonary infiltrates. Clinical manifestations usually appeared 24 to 48 hours after the patient was admitted and varied from mild respiratory distress to pulmonary failure in three; these three required tracheal intubation and mechanical ventilation. We found no evidence that pulmonary edema was caused by intravenous fluid overload. Oxygen therapy and ventilation were given to maintain the arterial PO2 at 80 mm Hg or greater, and erythrocyte transfusions were given to six women to correct anemia. Women with pulmonary injury were more likely to have multisystem derangement than a control group without respiratory involvement, but there were no clinical risk factors that were predictive at admission. This syndrome was probably caused by permeability pulmonary edema, likely mediated by endotoxin-induced alveolar-capillary membrane injury since other evidence of endotoxemia was common. Thrombocytopenia, hemolysis, intravascular coagulation, renal dysfunction, and transient cardiomegaly concomitant with hyperdynamic ventricular function are all explicable from endotoxin effects.

Biogenesis of tetrahydrofolate cofactors essential for bacterial growth and survival is blocked by sulfamethoxazole-trimethoprim. An intravenous form of the antimicrobial combination has recently been approved for the treatment of acute, symptomatic, bacterial pyelonephritis, recurrent urinary tract infections, shigellosis, and Pneumocystis carinii pneumonia. Intravenous sulfamethoxazole-trimethoprim has emerged as an invaluable agent for the management of selected infections, including bacterial meningitis and Salmonella bacteremia, where limited therapeutic alternatives exist. In addition, co-administration of intravenous sulfamethoxazole-trimethoprim with a carboxypenicillin provides an empiric treatment for the infected granulocytopenic patient that compares favorably with standard combinations. Adverse events unique to the intravenous form of the drug consist of phlebitis and fluid imbalances. Fluid overload results from the relatively large volumes of 5% dextrose solution required as diluent.

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.
