Renal biopsy was performed in 20 graft recipients to characterise the histological features associated with poor renal function concomitant with cytomegalovirus infection (CMV). Eight patients presented with proteinuria, three had microscopic haematuria at onset, and five were hypertensive. Infection was accompanied by clinical symptoms (fever, leucopenia, mild hepatic damage, or pneumonitis) in 15 patients. In all cases, serum creatinine was greater than 2 mg/dl. All patients showed some glomerular alteration on biopsy, and vascular changes were the predominant feature in seven cases. IgM and complement (C3) were found in the glomeruli of five of six patients studied by immunofluorescence. Serum creatinine was below 2 mg/dl at ten to 26 months following the infectious episode in four patients and between 2-3 mg/dl in three patients. The remaining 13 developed irreversible rejection and end-stage renal failure. We conclude that CMV, the most commonly recognised viral infection following transplantation, can cause renal changes, both glomerular (CMV glomerulopathy) and vascular (transplant vasculopathy), which may induce poor graft function.

Of 521 children with a previously untreated nephrotic syndrome, as defined by proteinuria greater than or equal to 40 mg/h/m2 and serum albumin less than or equal to 2.5 g/dL, entering the International Study of Kidney Disease in Children between January 1967 and April 1976, 389 showed minimal changes on renal biopsy. Of these, seven boys and three girls died, all before July 1972. Infection was the cause of death in six patients. One child died of dural sinus thrombosis, one died as a result of cardiorespiratory failure following salt-poor albumin infusion, and another died from chronic renal failure due to focal and segmental glomerulosclerosis not apparent on initial biopsy. The mode of death in the remaining child was uncertain. Analysis according to histopathologic subgroups of minimal change disease showed no statistically significant differences in the incidence of deaths, although mesangial abnormalities and tubular atrophy were associated with higher mortality than nil disease or focal glomerular obsolescence. Nine of the ten children who died had either failed to respond to initial prednisone therapy (initial nonresponders, n = 5), or responded but relapsed during the initial 8 weeks of treatment (early relapser, n = 4), even though only one quarter of the total sample were nonresponders or early relapsers (P less than .0005). Nearly one fifth of all initial nonresponders with minimal change nephrotic syndrome died. Thus the pattern of response to initial steroid therapy in patients with minimal change nephrotic syndrome may have prognostic significance.

Signs of damage to the glomerular basement membrane appearing as haematuria and proteinuria have been observed in 16 cases of proven acute yersiniosis. The infecting agent was Yersinia enterocolitica serotype O:3 in all. In a few cases a transient deterioration of the renal function was observed. The renal symptoms were not related to the acute febrile state, but seemed to appear about 14 days after the onset of yersiniosis and to be reversible in the observation period. Infection with other microorganisms known as nephritogenic was not found in spite of attempts to do so. Kidney biopsy was performed in one case and immunofluorescence microscopy showed deposits of immunoreactants. Based on these observations we suggest that acute glomerulonephritis can be included in the spectrum of complications of infection with Yersinia enterocolitica serotype O:3. The frequency of complicating glomerulonephritis in yersiniosis could not be estimated from this study.

Urinary tract infections are among the most frequently encountered health problems in patients of family physicians. The diagnosis requires the demonstration of more than 100,000 bacterial colonies per milliliter in a freshly voided urine specimen. Dysuria, proteinuria, and pyuria are unreliable diagnostic criteria. The pathogenesis is uncertain although vaginal colonization with enteric bacteria, voluntary avoidance of urination, and sexual intercourse are contributing causes. Vesicoureteral reflux is related to recurrent infection but a causal relationship has not been established. Urinary tract infection in children is related to decreased renal growth and kidney scars, but therapy of the infections does not prevent kidney damage. Infections disappear spontaneously in up to 40 percent of adult women. Bacteriuria in pregnancy, however, is related to low birth weight in infants and increased perinatal mortality. Asymptomatic bacteriuria need not be diagnosed or treated except in pregnant women. For symptomatic infections, short-term antibiotic therapy is as effective as long-term therapy. Prophylactic antibiotics and therapy by modification of behavior using a multifaceted regimen can reduce the frequency of recurrent infection.

In an attempt to identify causes of perinatal mortality and thence devise preventative strategies on the island of Jamaica, a study was made of the 1847 singleton perinatal deaths occurring over the 12-month period between 1 September 1986 and 31 August 1987. Complications of the pregnancy were elicited by questioning the mother as well abstracting data from the antenatal and clinical obstetric records. The deaths were classified using the Wigglesworth categorisation and the three largest groups were chosen for special study: antepartum fetal deaths, deaths of live birth from immaturity and deaths from intrapartum asphyxia. The medical features of the pregnancies were compared with data similarly obtained from 9919 women delivering singletons in the 2 months of September and October 1986 and who survived the first week of life. Unadjusted statistically significant associations were found with maternal syphilis, vaginal infection or discharge, bleeding in the first two trimesters, bleeding in the third trimester, lowest haemoglobin, highest diastolic and first diastolic blood pressures, highest level of proteinuria, diabetes and antenatal eclampsia. Logistic regression taking account of social, environmental and health behaviour variables showed the following significant relationships. Antepartum fetal death was associated with adjusted odds ratio (AOR) for syphilis 2.88 [95% confidence interval (CI): 1.91, 4.32], bleeding in third trimester 3.86 [2.73, 5.44], highest diastolic blood pressure (P < 0.0001), highest level of proteinuria (P < 0.0001), lowest Hb (P < 0.0001) and antenatal eclamptic fits AOR 4.62 [1.47, 14.50]. Deaths from immaturity were independently associated with bleeding < 28 weeks AOR 3.50 [2.39, 5.13], bleeding 28 + weeks AOR 1.93 [1.16, 3.22], highest diastolic blood pressure (P < 0.01) and highest level of proteinuria (P < 0.0001). Infection featured in deaths associated with intrapartum asphyxia, with syphilis AOR 2.17 [1.44, 3.26] and vaginal infection/discharge (P < 0.01) independently associated; other strong associations were bleeding < 28 weeks AOR 2.10 [1.57, 2.81], bleeding 28 + weeks AOR 2.32 [1.62, 3.33], highest diastolic blood pressure (P < 0.0001), first diastolic blood pressure (P < 0.0001) and antenatal eclampsia AOR 6.70 [2.63, 17.13]. For all perinatal deaths combined, independent features were syphilis AOR 2.06 [1.49, 2.85], vaginal infection/discharge (P < 0.001), bleeding < 28 weeks AOR 2.01 [1.60, 2.53], bleeding 28 + weeks AOR 2.65 [2.02, 3.48], highest diastolic blood pressure (P < 0.0001), first diastolic blood pressure (P < 0.0001), proteinuria (P < 0.0001) and antenatal eclampsia AOR 4.22 [1.76, 10.14]. The results help identify areas for monitoring and identifying pregnancies at highest risk.

A survey of 8080 subjects was conducted in Baltimore, examining the association between infection with hantaviruses and renal disease. Two groups (N = 6060) with no known risk factors were selected to establish a baseline antibody prevalence. Overall, antibody prevalence was 0.25%. Seroprevalence increased with age, without sex- or race-related differences. Patients with proteinuria showed the same patterns of infection but were more commonly seropositive (1.46%) than the reference group (OR, 3.23; P < .05). Infection among dialysis patients with end-stage renal disease was 2.76%, significantly higher than in the reference group (OR, 5.03; P < .05). In the proteinuria and the dialysis groups, hantavirus infection was consistently associated with a diagnosis of hypertensive renal disease. The association was unrelated to other chronic renal disease diagnoses. Overall, 6.5% of patients with end-stage renal disease due to hypertension were seropositive for a hantavirus. These data suggest that hantavirus infection is associated with hypertensive renal disease.

Forty-one hospitalized patients were randomized to be treated with cefuroxime (4.05 g/die) or cefotiam (5.30 g/die). Several patients received additionally furosemide (0.5 mg/kg body weight) intravenously. Serum creatinine and creatinine clearance did not show significant differences during versus after treatment in any of the groups. Cefotiam or cefotiam/furosemide treated patients displayed higher proteinuria and higher urinary excretion of lysosomal enzymes (leucine aminopeptidase) than patients treated with cefuroxime or cefuroxime/furosemide. Our data indicate higher tubulotoxicity of cefotiam compared to cefuroxime.

To assess the morbidity of S. haematobium infection in women of reproductive age (15-49 years) in the western part of Madagascar, the village of Betalatala with a prevalence of urinary schistosomiasis in women of 75.6% (95% confidence limit 69.3 to 81.9%) was compared with a neighbouring village with similar socio-economic characteristics and a prevalence of 5.0% (95% confidence limit 0 to 11.75%). The women were questioned in Malagasy about obstetrical history and urogynecological symptoms. They were examined gynaecologically, parasitologically and by ultrasonography. Important STDs were excluded by appropriate diagnostics. In Betalatala significantly more women reported a history of spontaneous abortion (P < 0.01), complaints of irregular menstruation (P < 0.001), pelvic pain (<0.05), vaginal discharge (P < 0.0001), dysuria (P < 0.05) and haematuria (P < 0.01) than in the control village. Biopsies were obtained from the cervix of 36 women with macroscopical lesions, and in 12 cases S. haematobium eggs were found by histological sectioning (33.3%). In the control village no eggs were detected in the histological sections of biopsies taken from 14 women. (P < 0.05). Infections with Candida albicans, Trichomonas vaginalis, Gardnerella vaginalis and Treponema pallidum were found in similar frequencies in both villages. In 9.8% of the women in Betalatala abnormalities of the upper reproductive tract were revealed by ultrasonography versus none in the women from the control village (P < 0.05). Echographic abnormalities of the urinary tract were present in 24% and 3% of the women in the study village and in the control village, respectively (P < 0.0001). These findings were accompanied by an elevated frequency of haematuria (55% versus 20%) and proteinuria (70.4% versus 25%) in the study population (P < 0.0001). Our study indicates that S. haematobium infection in women may not only cause symptoms in the urinary tract, but also frequently in the lower and upper reproductive tract.

Twenty seven ANA and dsDNA positive cases were selected from surgical files from years 1986 to 1997. Clinical, biochemical, morphological and immunofluorescence findings were correlated. Routine Haematoxylin and Eosin, Per iodic-Acid-Schiff and Methaneamine-Silver stains were used for all cases. Direct immunofluorescence was done whenever possible. Morphologically cases were grouped as per WHO criteria. Morphologically cases were quantified into Austin's chronicity and activity indices. Twenty one to thirty years was common age group. M:F:: 1:4.4. Anemia, skin rash and arthralgia were common extra-renal manifestations. There were 1,5,7,10 and three cases as per WHO class I to V respectively. All cases of class IV had active urine sediments and proteinuria. Four cases had high BUN and Serum creatinine levels. All (12) cases of immunofluorescence revealed group specific patterns. Five cases died. Infection was common cause of death. Twenty to thirty years, males, High BUN and Creatinine levels and high activity and chronicity indices were associated with poor prognosis.

A rare case of botryoid Wilms tumor is presented. The main clinical manifestations were persistent low-grade fever, malaise, and proteinuria associated with microhematuria. Ultrasonography revealed an echogenic mass in the right kidney, and a contrast-enhanced mass was found in the dilated collecting system by contrast-enhanced computed tomography. The surgically resected tumor was a polypoid, light-yellow, glistening mass that occupied a large part of the renal pelvis and originated from the pelvicaliceal wall. Part of the tumor extended to the proximal ureter, resulting in hydronephrosis in the involved kidney. No parenchymal lesion was observed. Microscopic examination revealed epithelial, stromal, and blastemal components, which indicated Wilms tumor. Infection had occurred in the hydronephrotic kidney, which presumably had caused the major presenting symptoms. The prognosis of our patient and previously reported cases of botryoid Wilms tumor was good compared with that of typical Wilms tumor, since the botryoid type can be detected at an early stage.
