A study group of 623 working women 30 to 49 years old with objective evidence of intake of phenacetin-containing analgesics and a matched control group of 621 women without such intake in 1968 were assessed six times from 1969 to 1978 for laboratory evidence of urinary-tract disorders. The two groups did not differ in development of bacteriuria, hematuria, or proteinuria. However, a low specific gravity of urine (study group vs. control group, 23 vs. 7 per cent) and a raised level of serum creatinine (6.7 vs. 0.9 per cent) were significantly more frequent in the study group (P less than 0.001). Adjusted analyses of mortality over 11 years showed significant differences between the groups in overall mortality (study group vs. control group, 39 vs. 13 deaths; P less than 0.001), mortality due to urinary-tract disorders (P = 0.033), and cardiovascular diseases (P = 0.008). We conclude that heavy users of analgesic mixtures in the course of a decade have a higher incidence of both abnormal kidney function and kidney-related mortality than do casual users and nonusers, but the absolute incidences remain small even among heavy users.

As found from a population study of women, those with arterial hypertension reported more often a history of toxaemia in pregnancy and had more often proteinuria, bacteriuria and impaired renal concentrating capacity than normotensive women. Serum potassium was found to be lower in treated as well as in untreated hypertensive women than in normotensive women.

Properly collected urine samples examined by qualified cytologists can aid in the diagnosis and management of various infectious and inflammatory renal parenchymal diseases. Patients with proteinuria, hematuria or bacteriuria will benefit most from renal cytologic examination. Exfoliative cells from renal parenchymal tumors often do not communicate with the collecting system. Some disseminated neoplasms, such as lymphoma or myeloma, can be diagnosed and followed by cytologic study.

Three clinical cases of toxic nephropathy in young horses were ascribed to gentamicin toxicity. Criteria for defining gentamicin-induced nephrotoxicosis were a serum urea nitrogen value greater than the pretreatment value or cylindruria, hematuria, and proteinuria in the absence of pyuria and bacteriuria. Recommended doses of gentamicin had been given in all cases. The nephropathy was reversible in 1 case in which the toxicosis was detected early and was treated by volume diuresis and drug withdrawal.

One hundred and thirty patients with primary chronic pyelonephritis diagnosed radiologically or by nephrectomy, 84 with unilateral and 46 with bilateral disease, have been followed for six to 240 months. The clinical and radiological features of the disease at presentation, together with its influence on pregnancy, have been analysed. Serial observations of bacteriuria, blood pressure and renal function have been made during follow up and the intravenous urogram (IVU) has been repeated after five years in most patients. Although the disease probably starts in early childhood it often presents to the nephrologist in young adults, mainly women, as symptomatic urinary tract infection, hypertension, renal insufficiency or a combination of these features. Though associated with increased morbidity in pregnancy it does not usually interfere with fertility and in this series it did not cause increased fetal loss. Repeated urinary tract infections and hypertension are common events. Proteinuria is usually minimal and when present is associated with hypertension. The disease in most patients with unilateral disease runs a benign course; a poorer prognosis is associated with bilateral disease, hypertension and proteinuria. Since we found no association between frequent urinary infections and declining renal function we suggest that only symptomatic urinary infection should be treated in adults with chronic pyelonephritis.

This study analyzed the interleukin 6 (IL-6) response in 114 children with suspected urinary tract infection (UTI). Urine and serum samples were obtained at the time of enrollment. There were 90 children with UTI, 41 with and 49 without a temperature > or = 38.5 degrees C. The remaining 24 children did not have bacteriuria; 11 were febrile and 13 were not. The urinary IL-6 concentrations were higher in the children with UTI (mean, 129 units/ml) than in the children without bacteriuria (mean, 7 units/ml, P < 0.01). In contrast the serum IL-6 did not differ between children with or without UTI or between children with or without a temperature > or = 38.5 degrees C. The urinary IL-6 response was higher in children who were infected with P fimbriated Escherichia coli than in other children with UTI (P < 0.05). There was a correlation of urinary IL-6 with the degree of proteinuria, hematuria and urinary leukocyte counts (P < 0.001, P < 0.05, P < 0.05, respectively) but not with serum IL-6, CRP or temperature, and of serum IL-6 to C-reactive protein (P = 0.053) and renal concentrating capacity (P < 0.05). The results demonstrate that infections of the urinary tract activate an IL-6 response in children and that the magnitude of the IL-6 response is influenced by the properties of the infecting strain.

This study represents a retrospective analysis of pregnancies with chronic arterial hypertension and their outcomes. The aim was to evaluate the influence of arterial hypertension on 101 essential and 109 cases of secondary hypertension in comparison to the control group consisting of 499 normotensive pregnancies. According to the obtained data, 27.7% of the women with chronic hypertension had proteinuria, 61% had bacteriuria and 58.6% had superimposed EPH gestosis. The occurrence of EPH gestosis among the controls was 5.6%, that is significantly less than in the experimental group (X2 = 282.8%; p < 0.001). The outcomes of pregnancies associated with chronic hypertension were: 19% preterm deliveries compared to the controls in which only 9.2% preterm deliveries occurred (X2 = 14.4; p < 0.001). Newborns from pregnancies with essential hypertension were significantly heavier, weighing 3177 +/- 734 g, than those from pregnancies with secondary hypertension, which weighted 2578 +/- 932 g. Perinatal mortality was higher in the study group and significantly higher in the pregnancies with associated secondary hypertension (30.3%) than in pregnancies associated with essential hypertension (15.8%).

The prevalence of bacteriuria as well as bacterial virulence and host factors were studied in 514 diabetic outpatients and 405 nondiabetic controls. The prevalence of bacteriuria was not significantly higher in diabetic women (15/239, 6.3%) than in age-matched nondiabetic women (8/236, 3.4%). In diabetic and nondiabetic men, the prevalence was also similar but lower than in women. E. coli was found in 55% of urine cultures with significant growth from diabetic patients, while in 91% of positive cultures from nondiabetic controls. Most E. coli strains lacked ability of P-fimbriae-mediated adhesion and aerobactin-mediated iron uptake, indicating low bacterial virulence. Long-term metabolic control (HbA1c), prevalence of retinopathy, neuropathy and previous foot ulcers were similar in bacteriuric and nonbacteriuric diabetic patients, matched according to gender, age, and duration of diabetes. Renal function was also similar, though the frequency of proteinuria and elevated blood pressure tended to be higher in the bacteriuric than in the noninfected group. Eight-three percent of the bacteriuric patients reported previous urinary tract infections but only 61% of nonbacteriuric patients (p = 0.07). As compared to non-diabetic women, diabetic women reported significantly more previous urinary tract infections (p < 0.01). In conclusion, the prevalence of bacteriuria in diabetic outpatients was not significantly higher than in non-diabetic outpatients or healthy volunteers. No studied host factor was clearly associated with bacteriuria in diabetic patients, although proteinuria and hypertension tended to be more common. The infecting E. coli strains were of low virulence.

The specific gravity of urine (SG) indicates the number and weight of solute particles in urine; its measurement is helpful in interpreting proteinuria detected by dipstick tests and in monitoring adequate hydration in patients with nephrolithiasis. Four methods for measuring SG or osmolality of urine are currently available (depression of the freezing-point, urometry, refractometry, cation exchange on a reagent strip). Using a recently developed reagent strip, we have measured SG in morning urines of 340 non-selected outpatients and compared the results with SG measurements by refractometry of the same urines. In 86.2% of all urines, a good positive correlation between SG measured by reagent strip and refractometry was noted (r = 0.913, p = 0.0001). In 13.8% of the urines, however, the SG measured by reagent strip deviated by more than +/- 5 from the value obtained by refractometry; in 90% of these urines, glucosuria (reagent strip values too low or too high), proteinuria (values too high), or bacteriuria/leukocyturia (values too low or too high) could be found. In alkaline urine (pH > 7.0), SG values obtained by reagent strip have to be corrected by +5.

In 103 subjects with asymptomatic isolated haematuria (persisting for more than 6 months in the absence of proteinuria, bacteriuria, impaired haemocoagulation or urological disease) renal biopsy was performed. The mean age of the patients was 25.2 years, range 14-58 years. In 94% glomerular changes were detected--most frequently minimal glomerular lesions (67%) and proliferative mesangial glomerulonephritis (15%). Focal segmental proliferative glomerulonephritis was rare (4%). Immunofluorescent examination revealed IgA nephropathy in 40% (all cases of diffuse and focally segmental proliferative glomerulonephritis and one quarter of minimal glomerular lesions). Changes of tubules and interstitium were recorded in 26%, with the exception of one patient they were always associated with glomerular affection. From the investigation ensues that the predominating cause of isolated asymptomatic haematuria, not clarified by non-invasive examination, is usually not serious and is an affection frequently associated with tubulointerstitial changes. As many as 40% of isolated cases of haematuria may be the manifestation of IgA nephropathy. The deposition of IgA is more frequently associated with a more advanced grade of glomerular affection. Indication of diagnostic renal biopsy in isolated haematuria remains individual.
