The Diaphane-program instituted under the authority of the French Society of Nephrology has been steadily expanding since 1972. By December 1977, about 1500 patients treated in 30 public and private Dialysis Centres were followed up by this system. Full coverage of expenses is provided by the participating Centres. The statistical work presented in this report involves 1572 adult patients treated between June 1972 and December 1976 in 24 dialysis centres. The amount of collected data and the duration of the observation period permit to build up evolutive profiles of the population of patients treated in France by maintenance hemodialysis, of the various techniques and strategies used and of the main complications recorded in the patients. 1. Mean age of patients at start of dialysis is steadily increasing, from 40.1 years in 1972 to 48.2 years in 1976. 2. The predominance of male patients, constant over each year, may be explained by an increased proportion in man of chronic glomerulonephritis and renal vascular diseases. The sex-ratio in patients with chronic pyelonephritis is close to the one recorded in the French population. 3. The regular decrease of the mean plasma creatinine level at time of first dialysis recorded since 1972, is probably related to an earlier start of treatment. However, 10.6 per cent of the patients taken on treatment in 1975-1976 still had a plasma creatinine greater than or equal to 200 mg/100ml. 18.7 per cent had a diastolic blood pressure greater than or equal to 120 mmHg, and exsudative lesions at eye fundi examination were found in 33.5 per cent. The delay in initiating dialysis treatment may account for the frequency of early acute cardiopulmonary complications such as pulmonary oedema and pericarditis and also for the increase in the mortality rate recorded during the first year of treatment: 12.1 per cent instead of 6.2 per cent during the second year. This particularly relevant for the younger age group of patients. 4. There seems to be some social disparity concerning the detection of renal disease and the conditions under which dialysis treatment is started: chronic renal disease is detected at an earlier stage and dialysis treatment initiated for lower values of plasma creatinine and of diastolic blood pressure in patients belonging to the "higher income" group of population. 5. The percentage of patients dialysed twice a week is steadily increasing, whereas the average weekly dialysis time decreases, being about 15 hours in 1976. Day and evening dialysis replace overnight dialysis. Disposable flat-plate dialysers are used increasingly. 6. Episodes of hypotension and cramps are the incidents most frequently recorded during the dialysis sessions. Risk factors evidenced in the occurrence of hypotensive accidents are: the female sex, age greater than or equal to 55 years in males, orthostatic blood pressure drop at the end of previous dialysis, weight loss of more than 4 per cent of total body weight during dialysis...

A case of Turner's syndrome is presented; many congenital defects were detected. Predominant clinical findings were cheilognatoschisis, respiratory distress, caused by congenital bronchiektasis and chronic hypokalemia with paroxysmal attacks of paralysis and tetania. Hypokalemia was mainly due to gastrointestinal losses as a consequence of permanent vomiting in the presence of stomach atonia and hiatus insufficiency or because of "third space losses", while a subileus persisted chronically. Furthermore also a renal loss of serum potassium was evident in the patient's predialytic time. Basic renal diseases were pyelonephritis, renal damage from phenacetine abuse, or probably even a nephropathy due to potassium depletion. Uraemia was controlled by dialysis treatment and by a dialysate consisting of 7 and 6 mmol/l potassium respectively. The result of this intense therapy was physical rehabilitation and the patient finally could resume her professional work again.

Chronic atrophic pyelonephritis is associated with vesicoureteric reflux in infancy. Reflux disappears during childhood in 50% of cases. It is more commonly detected in infants (49%) and children (26%) with infection than in adults (4.4%). Severe reflux may persist in adults and is usually (94%) associated with scarring. Patients with end-stage renal failure due to pyelonephritis are much younger than patients with end-stage renal failure due to other causes. The incidence of reflux according to sex is equal in infancy, but after infancy both pyelonephritic scarring and reflux are far more common in females. Infection is the likely cause of progressive scarring in females. Hypertension is associated with chronic atrophic pyelonephritis. Proteinuria is the worst prognostic feature in patients with reflux nephropathy and pyelonephritic scarring. Intrarenal reflux determines the site of scarring. The role of surgical correction of vesicoureteric reflux remains uncertain, but meticulous control of infection appears to prevent progressive scarring.

By a nephroptosis already in childhood an obstruction of the urine flow with reduction of the drainage effect and thus the appearance of a pyelonephritis may develop. Changes at the vascular pedicle are also possible on account of the abnormal mobility of the kidneys so that without treatment from there may result parenchymatous and functional lesions which, as a rule, become manifest only at adult age. On the basis of own experiences which support themselves on the results of 29 children with nephroptosis we recommend the nephropexy in childhood. The operation is an active prophylaxis of the pyelonephritis caused by nephroptosis with its deleterious sequelae.

The presence of antibody coated bacteria in the urinary sediment was correlated with the infection site in 151 patients. 86 patients were followed regularly and support sequential data. A positive test is noted in most of the chronic pyelonephritis cases in all the prostatitis cases and in some of the chronic infection on bladder disease. In recurrent cystitis the test is generally negative as in acute pyelonephritis seen within 24 hours.

An immunofluorescence test for detection of antibody-coated bacteria in urinary sediments of patients with significant bacteriuria was carried out. According to previous data antibody-coated bacteria were not observed in urines from patients with cystitis, while they were observed in urine specimens from patients with pyelonephritis. These results confirm that the immunofluorescence test can be useful in distinguishing infection of kidney from infection of the bladder.

Hypertensives in pregnancy are not so grossly distinct and different from adult hypertensives if reference is made to the underlying arterial anomalies and malformations of the parenchyma and their incidence. It is, however, in this group that the limited way in which the active remnant of parenchyma, once constrained by these anomalies, can compensate for the changes in pressure and volume sensitivity imposed by pregnancy is most evident; these changes may be caused by pyelonephritis of pregnancy (genuine but rare), eclampsia of the primigravida, progressive hypertension in the multigravida, or certain cases of late hypertension, menopausal hypertension, or hypertension as a late result of a simple juvenile eclampsia. This series contains a particularly high percentage (21%) of cases of hypertension due to unilateral renal arterial ischaemia which are curable.

A review of 22,971 pregnancies from 1969-74 reveals that the reasons for requesting excretory urography were renal colic of pregnancy 11, pyelonephritis 8, renal contusion 2, threatened abortion 1, and suspected degeneration of fibroid 1. The final diagnoses were similar except that two patients with torsion of ovarian cysts and a renal calculus were discovered. The only intravenous pyelographic examination that was decisive for diagnosis was in a patient with a ureteric calculus. Careful clinical correlation should reduce excretory urography during pregnancy.

The present studies have confirmed a severe urinary concentrating defect early in the course of experimental enterococcal pyelonephritis. This defect in maximum concentrating ability was almost completely reversed immediately following indomethacin or sodium meclofenamate intravenously. This effect of indomethacin and sodium meclofenamate was transient and was not associated with a fall in numbers of enterococci per gram of kidney. Injection of indomethacin or sodium meclofenamate in noninfected rats had no effect on maximum renal concentrating ability. The potential mechanisms by which indomethacin and sodium meclofenamate, inhibitors of renal prostaglandin synthesis, could reverse a defect in maximum urinary concentration are discussed.
