ABSTRACT

BACKGROUND: Desmopressin (an analogue of antidiuretic hormone) holds an important place in the treatment of primary nocturnal enuresis. According to some long-term trials its action is mainly symptomatic. The benefit of treatment and persistence of the effect in relation to the expected decline of enuresis in 15% children/1 year is discussed. METHODS AND RESULTS: The open multicentre trial lasted 42 months. In the first stage 265 patients (164 boys, 101 girls) aged 9.4 +/- 2.8 (5-18 years) were given desmopressin (nasal drops) to achieve a 4-week dry integral. Enuresis stopped in 207/265 (78.1%) children within six (median) weeks of treatment after an effective dose of 10.5 micrograms (median) based on titration. During the second stage 55/265 children (25 boys and 30 girls) proceeded with treatment for 2-30 (median 12) months, one boy did not complete the trial. An effective dose was administered for 3.5 months (median) and then the dose declined depending on the effect by 3.5 micrograms (1 drop) per months (median). In the titration stage enuresis receded in 89.1% (49/55) children. After the first year of the trial there were 72.7% responders (p < 0.001, as compared with the assumed decline), after two years 70.9% (p < 0.01) and after three years 61.1% children (p < 0.05). The trial was completed by 61.1% (33/54) children as respondents. 23 of them 17-38 months after termination of treatment. 29.6% (16/54) patients were relapsing responders on long-term treatment, 5.6% (3/54) patients completed the trial as partial responders and 3.7% (2/54) children as non-responders. Minor side-effects were recorded during the titration stage in 4.5% children, during long-term treatment 5.4% children. The osmolality of morning urine increased during treatment regardless of the final effect (p < 0.01). The authors did not find a significant relationship between age, sex, familial incidence of enuresis, period of treatment and the achieved effect. CONCLUSIONS: The authors provided evidence of a rapid onset of the effect of desmopressin and a high effectiveness throughout the trial. The osmolality of the morning urine was not a reliable predictive factor of the effect. In the authors opinion long-term treatment is important for development of regulation and regression of complaints. During a relapse the authors recommend return to maintenance treatment and gradual discontinuation after 6-12 months. Desmopressin treatment is in the authors' opinion safe, well tolerated and very useful.

ABSTRACT

Escherichia coli was isolated from the urine of patients with pyelonephritis, with urinary tract infections other than pyelonephritis and with asymptomatic bacteriuria. Surface properties of the strains were analyzed by the salting-out aggregation test (SAT), hydrophobic interaction chromatography (HIC), Congo red binding (Crb), agglutination of erythrocytes (MRHA) and latex particles covered by digalactoside (PF) and by adherence to tissue culture cells. In addition, a DNA probe for the pap gene was used. The DNA probe detected the highest proportion of strains with pap gene in the group of patients with pyelonephritis, lower in the urinary tract infections other than pyelonephritis and the lowest in the group with asymptomatic bacteriuria. Tests for P-fimbriae (PF, MRHA) showed a similar distribution. Hydrophobicity measured by SAT and by HIC did not show differences among the tested groups of strains. The results suggest that factors other than the P-fimbriae and hydrophobicity may contribute to the persistence of E. coli in the urinary tract.

ABSTRACT

Subcutaneous recombinant human erythropoietin (rHuEpo) treatment of renal anemia was performed in four boys and eight girls on CAPD, aged 0.8-12.5 (mean 7.4) years. In contrast to previous studies, our therapeutic goal was not set with a hematocrit of 30% but with full correction of anemia. Following a maximum weekly rHuEpo dosage of median 120 (range 100-240) IU/kg body weight, hematocrit increased in 10 children from 24 (14-29)% within 12 (4-17) weeks to 40.1 (33.5-48.4)%. The weekly increase in hematocrit was 1.27 (0.5-3.1)%. The corrected reticulocyte count increased from 1.3 (0.7-1.8)% to 2.3 (1.4-3.9)% within 4 (2-6) weeks. Eight children fulfilled the protocol; six with an uncomplicated course were able to maintain a hematocrit of 37.1 (35.1-42.7)% with only one sc medication per week of approximately two-thirds of their highest weekly rHuEpo dosage. No serious adverse effect of rHuEpo therapy was observed.

ABSTRACT

The method of sequence scintigraphy of the kidney with 99mTc-DTPA (diethylene triamine pentacetic acid) and subsequent determination of glomerular filtration rate by means of a gamma camera and computer were applied in examining 160 children with different diseases of the kidneys and urinary tract. By modifying the commercial computer program a study with quantitative evaluation of some functional parameters was designed, involving also the determination of the overall and of separate values of GF 99mTc-DTPA according to G. Gates. The main advantages of the applied method are its noninvasiveness, speed, safety, low radiation load, and its relatively broad use in diagnostic nephrological practice particularly in children.
