Adults with autosomal dominant polycystic kidney disease (ADPKD) who have overt proteinuria (>300 mg/d) have higher mean arterial pressures, lower creatinine clearances, larger renal volumes, and a more aggressive course of renal disease than ADPKD patients without proteinuria. This study examines the relationship between proteinuria and microalbuminuria and similar factors in ADPKD children. A total of 189 children from 81 ADPKD families was included in the analysis. The ADPKD children (n = 103) had significantly greater urine protein excretion rates than the non-ADPKD children (n = 86) (3.9+/-0.3 versus 2.8+/-0.2 mg/m2 per h, P < 0.001). Children with severe renal cystic disease (> 10 cysts; n = 54) had greater protein excretion than those with moderate disease (< or = 10 cysts; n = 49) (4.4+/-0.5 versus 3.3+/-0.2 mg/m2 per h, P < 0.05). The ADPKD children had significantly greater albumin excretion rates than the non-ADPKD children (32+/-6 versus 10+/-2 mg/m2 per 24 h, P < 0.001), and a higher percentage of ADPKD children had significant microalbuminuria (>15 mg/m2 per 24 h in boys and >23 mg/m2 per 24 h in girls) than their unaffected siblings (30% versus 10%, P < 0.05). Thirty percent of ADPKD children had albuminuria and 23% had overt proteinuria. For all ADPKD children, there was no correlation between proteinuria and hypertension. However, there was a significant correlation between urinary protein excretion and diastolic BP among children diagnosed after the first year of life (r = 0.23, P < 0.05). Therefore, proteinuria and albuminuria occur early in the course of ADPKD and may be markers of more severe renal disease. 相似文献

Microalbuminuria is a considerable good indicator of atherogenic disease and cardiovascular risk. In the arterial hypertension, the main centre organ is the kidney. Structural and functional changes that happen in the hypertensive nephropathy are going to cause alterations m the albumin urinary excretion. The authors have done a revision of the main factors which can origin the existence of microalbuminuria in patients with arterial hypertension, and they conclude that this is an useful biochemist indicator in order to evaluate the degree of renal disease in these patients. 相似文献

To study the potential role of sympathetic activity in the pathogenesis of arterial hypertension associated with autosomal dominant polycystic kidney disease (ADPKD) and to analyze its relationship with 24-hour blood pressure pattern, plasma catecholamines and 24-hour ambulatory blood pressure monitoring were evaluated in 30 ADPKD hypertensive patients (of which 17 without and 13 with renal failure) and in 50 essential hypertensives. The groups were matched for sex, body mass index, known duration of hypertension, and clinic blood pressure. Plasma catecholamines, determined in resting position, were higher in ADPKD patients without renal failure than in essential hypertensives. Nighttime diastolic blood pressure was higher and the percentage day-night difference in mean blood pressure was lower in hypertensives with ADPKD compared to patients with essential hypertension. Blood pressure was significantly correlated with plasma noradrenaline in ADPKD patients, independently of renal function. No significant differences were observed between ADPKD patients with and without renal failure, with respect to plasma catecholamines, 24-hour daytime and nighttime ambulatory blood pressures and the percentage day-night difference in mean blood pressure. 相似文献

The Modification of Diet in Renal Disease Study showed a beneficial effect of a lower-than-usual blood pressure (BP) goal on the progression of renal disease in patients with proteinuria. The purpose of the present analyses was to examine the achieved BP, baseline characteristics that helped or hindered achievement of the BP goals, and safety of the BP interventions. Five hundred eighty-five patients with baseline glomerular filtration rate between 13 and 55 mL/min per 1.73 m2 (0.22 to 0.92 mL/s per 1.73 m2) were randomly assigned to either a usual or low BP goal (mean arterial pressure < or = 107 or < or = 92 mm Hg, respectively). Few patients had a history of cardiovascular disease. All antihypertensive agents were permitted, but angiotensin-converting enzyme inhibitors (with or without diuretics) followed by calcium channel blockers were preferred. The mean (+/- SD) of the mean arterial pressures during follow-up in the low and usual BP groups was 93.0 +/- 7.3 and 97.7 +/- 7.7 mm Hg, respectively. Follow-up BP was significantly higher in subgroups of patients with preexisting hypertension, baseline mean arterial pressure > 92 mm Hg, a diagnosis of polycystic kidney disease or glomerular diseases, baseline urinary protein excretion > 1 g/d, age > or = 61 years, and black race. The frequency of medication changes and incidence of symptoms of low BP were greater in the low BP group, but there were no significant differences between BP groups in stop points, hospitalizations, or death. When data from both groups were combined, each 1-mm Hg increase in follow-up systolic BP was associated with a 1.35-times greater risk of hospitalization for cardiovascular or cerebrovascular disease. Lower BP than usually recommended for the prevention of cardiovascular disease is achievable by several medication regimens without serious adverse effects in patients with chronic renal disease without cardiovascular disease. For patients with urinary protein excretion > 1 g/d, target BP should be a mean arterial pressure of < or = 92 mm Hg, equivalent to 125/75 mm Hg. 相似文献

Some patients with essential hypertension manifest increased urinary albumin excretion (UAE). Hypertensive patients with microalbuminuria manifest abnormal circadian variation of blood pressure, increased serum levels of LDL-cholesterol and lipoprotein(a), a greater rise of serum insulin in response to an oral glucose tolerance test, and greater thickness of the carotid artery than patients without microalbuminuria. A 7 year follow-up of 141 hypertensive patients, 54 with microalbuminuria and 87 without microalbuminuria, we observed 12 cardiovascular events in patients with microalbuminuria and only 2 events in the patients with normal urine albumin excretion (P < 0.0002). Creatinine clearance decreased more in patients with microalbuminuria than in those with normal UAE. In conclusion, hypertensive individuals with microalbuminuria manifest a greater incidence of cardiovascular events and more decline in renal function than patients with normal UAE. We propose that measurements of UAE may be a useful marker for cardiovascular risk in patients with essential hypertension. 相似文献

Urinary protein excretion is generally less than 1 g/24 h in autosomal dominant polycystic kidney disease (ADPKD), and the association of the nephrotic syndrome with this condition is considered rare. A patient with ADPKD associated with nephrotic-range proteinuria is described. She exhibited a relatively rapid impairment of her renal function. An open renal biopsy revealed focal segmental glomerulosclerosis (FGS) with features consistent with secondary FGS. Twenty-one patients with ADPKD and nephrotic syndrome were retrieved from the literature. Fourteen of them (including this case) had a histopathologic evaluation, and FGS was the dominant diagnoses (five patients). Next in frequency were minimal-change disease and membranous nephropathy, with two patients each. Five other patients had a variety of diagnoses. Thus, it is difficult to ascertain if these associations are coincidental or represent a specific pathogenetic relationship. The evaluation of the data also suggests that the presence of proteinuria and nephrotic syndrome accelerates the course of ADPKD toward ESRD. 相似文献

Microalbuminuria has been proposed as a potential atherosclerotic risk factor in hypertensive individuals. The aim of this cross-sectional population study was to analyse whether microalbuminuria is related to a higher prevalence of cardiovascular disease, and a more atherogenic risk profile, and reversely related to the use of antihypertensive drugs. In a major health screening at the State University Hospital in Copenhagen, including urinary albumin excretion, glomerular filtration rate, blood pressure (BP), electrocardiogram, body mass index, plasma lipoproteins, fibrinogen, and albumin, and information regarding a history of acute myocardial infarction, smoking, and antihypertensive drugs, 1254 participants without diabetes mellitus or renal/urinary tract disease had arterial hypertension. Age range was 30-70 years. Microalbuminuria (nocturnal urinary albumin excretion >15 microg/min) occurred in 5%, and cardiovascular disease (previous acute myocardial infarction or electrocardiographic Q-waves) also in 5% of the study population. Microalbuminuric hypertensive subjects were characterized by higher age and systolic BP, and a male predominance, as compared to normoalbuminuric hypertensive subjects. The frequency of cardiovascular disease was similar in the two groups. In contrast, when analysed as a continuous variable, a one unit increase in the logarithmically transformed urinary albumin excretion significantly increased the likelihood of cardiovascular disease (odds ratio [95% confidence interval] 1.32 (1.02-1.70); P < 0.05), and this relation was independent of age, sex, and conventional atherosclerotic risk factors. Participants who were effectively treated with antihypertensive drugs did not have a lower urinary albumin excretion than insufficiently treated or untreated participants. It is concluded that slightly elevated albumin excretion in the urine is not only a pressure-dependent functional phenomenon in the glomerular vessel walls, but associated with permanent atherosclerotic abnormalities in the entire vascular system. 相似文献

Among all inherited cystic kidney diseases, the commonest are polycystic kidney diseases, which include 2 diseases characterized by their pathological characteristics and their mode of inheritance, namely autosomal dominant or recessive. Autosomal dominant polycystic kidney disease is usually diagnosed in adulthood and is related at least to 2 different genes; PKD1 gene on chromosome 16 accounts for 85% of cases. This frequent disease (1 in 1,000 people) leads to end-stage renal failure in most patients at a mean age of 55 years. Renal ultrasonography allows its detection at an early stage, during childhood or adolescence, and even in utero in some cases. Autosomal recessive polycystic kidney disease, related to a single gene mapped to chromosome 6, is a rare disease, usually diagnosed during infancy because of enlarged kidneys and hypertension. The early occurrence of advanced renal failure is uncommon and only 1/3 of patients require renal replacement therapy during childhood. The term "polycystic kidney disease" should be limited to these 2 diseases; however there are many other inherited conditions including renal cysts like tuberous sclerosis or Hippel-Lindau's disease in adults, and several malformative syndromes in children. 相似文献

To examine clinical features and the prognostic factors for renal function in patients with autosomal dominant polycystic kidney disease (ADPKD), a total of 118 patients (60 men and 58 women) were followed for 3 to 192 months (mean 77 months). The mean age of men at the diagnosis of ADPKD was younger than that of women. Main Symptoms were hematuria, hypertension and proteinuria. Forty-one % of the patients showed deterioration of renal function at the diagnosis. The rate of residual volume of renal parenchyma on CT findings was correlated well with renal function. Twenty-eight % of the patients preserved good and stable renal functions for over 5 years, while most of others had deterioration in their renal function. Thirty-four % of the patients started dialysis within 79 +/- 62 months from the diagnosis. The frequency of end stage renal failure was 7% at 40 years, 21% at 50 years, 36% at 60 years and 63% at 70 years old, respectively. Men needed hemodialysis at younger ages than women. Renal function of the patients with hypertension was worse than that of the patients without hypertension. The ratio of the value of P.S.P.120 to that of serum creatinine (PSP120/sCr), and the rate of residual volume of renal parenchyma revealed distinct prognostic factors for renal function. 相似文献

PURPOSE: Access to retroperitoneal structures via the laparoscope has become established for various conditions. This minimally invasive approach has distinct advantages over conventional open surgery. We document our experience with laparoscopic cyst decortication for diseases of the kidney, including simple and complex cysts, multiple cysts and autosomal dominant polycystic kidney disease. MATERIALS AND METHODS: We retrospectively reviewed the records of 17 patients who underwent a total of 20 procedures. Cases were categorized as polycystic kidney disease and nonpolycystic kidney disease. Factors analyzed were estimated blood loss, length of surgical procedure, hospital stay and complications. Followup included radiographic studies (computerized tomography and/or renal sonography) and patient subjective pain relief, as determined by clinical records and telephone interview. RESULTS: Nine and 11 procedures were done for nonpolycystic kidney disease and polycystic kidney disease, respectively. Of the 8 patients with polycystic kidney disease 3 underwent repeat procedures. Followup was 3 to 63 months (average 26). All patients with simple cysts who were treated for pain were pain-free at the latest followup. Of the 10 procedures 9 (90%) performed for pain relief in polycystic kidney disease successfully produced immediate pain relief. Pain-free status decreased with time with 7 of 8 (87.5%) pain-free after 6 months, and 5 of 7 (71.4%) at 1, 4 of 6 (66.7%) at 2 and 1 of 4 (25%) at 3 years. A repeat operation successfully relieved recurrent pain in 2 of 3 cases (66.7%). Of the 7 patients with polycystic kidney disease who underwent surgery for pain relief 5 (71%) are currently pain-free. CONCLUSIONS: Laparoscopic renal cyst decortication is an effective minimally invasive treatment for painful simple cysts. It is also effective for short to intermediate pain relief in autosomal dominant polycystic kidney disease. Long-term followup suggests that a repeat procedure may be necessary to maintain adequate control of symptoms in polycystic kidney disease. 相似文献

Recently, it has been reported that Na,K-ATPase in the renal epithelia of human autosomal dominant polycystic kidney disease and cpk mouse, a murine model of autosomal recessive polycystic kidney disease, mislocates to apical plasma membrane and that mislocated Na,K-ATPase causes the cyst formation. Whether the DBA/2FG-pcy mice, which are presumably a suitable model for autosomal dominant polycystic kidney disease, also exhibit the reversal polarity of Na,K-ATPase localization was examined. Kidneys of newborn DBA/2FG-pcy mice, and those at early and late stages of cyst development were examined by immunohistochemical techniques. At any stage, abnormal distribution of Na,K-ATPase on the apical membranes of tubular epithelial cells could not be detected. It is suggested that cysts can be formed without reversed polarity of Na,K-ATPase distribution in pcy mice. 相似文献

BACKGROUND: Tuberculosis is a recognized complication following renal transplantation. Patients with autosomal dominant polycystic kidney disease are increasingly being offered renal transplantation as an alternative to chronic hemodialysis. These patients are uniquely susceptible to serious upper urinary tract infections that are associated with significant morbidity and mortality. While involvement with gram-negative organisms is well described, mycobacterial infection of native polycystic kidneys after transplantation has not been addressed. METHODS: A case report of a renal transplant recipient who suffered an isolated Mycobacterium tuberculosis infection of a native polycystic kidney and a literature review. RESULTS: Despite appropriate drug therapy, the infection proved refractory, and the patient required nephrectomy. CONCLUSIONS: Mycobacterial tuberculosis, though not common, must be recognized as a potential source of infection of native polycystic kidneys in immunocompromised transplant recipients. Similar to the pattern observed with more common pathogens, these infections may be difficult to eradicate with standard antimicrobial drug regimens. 相似文献

Medullary cystic kidney disease (MCD) is characterized by multiple renal cysts at the corticomedullary boundary area, by autosomal dominant inheritance, and by onset of chronic renal failure in the third decade of life. We report on a family with three affected individuals of both sexes in two generations presenting with end-stage renal failure at age 22-31 years. Primarily diagnoses considered included unclassified hereditary nephropathy and autosomal dominant polycystic kidney disease. Careful evaluation of all findings, initiated after investigation of renal morphology with CT, revealed features characteristic for MCD and led to the final diagnosis of MCD. We conclude that MCD is an important differential diagnosis for polycystic kidney disease in young adults with end-stage renal failure. Establishing the correct diagnosis has considerable impact for genetic counselling. 相似文献

Nephropathy of non-insulin-dependent diabetes mellitus (NIDDM) is the most common cause of end-stage renal failure (ESRF) in Western countries. This study investigates the clinical and histologic putative predictors of disease progression, with the final goal to identify patients at risk who may benefit from early diagnosis and intervention. It examines by repeated measurements of BP, blood glucose, serum creatinine, and urinary protein excretion rate 65 consecutive NIDDM patients with clinical, persistent proteinuria and biopsy-documented typical diabetic glomerulopathy (class I; n = 30), predominant nephroangiosclerosis (class II; n = 23), or nondiabetic type glomerulopathy (class III; n = 12), whose severity of renal tissue involvement was precisely quantified by a global histologic score. Baseline parameters and progression to renal end points, i.e., doubling of baseline serum creatinine, dialysis, or transplantation, were univariately and multivariately correlated by proportional hazards regression models. The median kidney survival time in the overall study population was 3.07 yr. Thirty-seven percent of patients reached an end point during a median (range) follow-up of 1.8 yr (0.4 to 5.7 yr). By univariate and multivariate analysis, kidney survival significantly correlated with baseline urinary protein excretion rate (P = 0.04 and P = 0.04, respectively) and renal tissue injury score (P = 0.0001 and P = 0.02, respectively), but not with the histologic classes. Patients with a urinary protein excretion rate < or = 2 g/24 h, or > 2 g/24 h with a histologic score < 7, never reached an end point. All patients with urinary protein excretion > 2 g/24 h and a histologic score > 13 progressed to ESRF over a median of 1.6 yr. No differences in other baseline parameters or in BP and diabetes control during follow-up accounted for these different outcomes. In NIDDM as well as in nondiabetic chronic renal disease, quantification of urinary protein excretion rate--independent of the pattern of underlying glomerular involvement--reliably discriminates progressors from nonprogressors and, combined with precise quantification of renal tissue injury, reliably predicts risk of ESRF. This information may be used to set guidelines for early diagnosis and appropriate intervention to reduce the number of diabetic patients who will need renal replacement therapy in years to come. 相似文献

There is controversy as to whether increased plasma levels of human atrial natriuretic peptide (hANP) in patients with type 1 diabetes mellitus may contribute to the development of diabetic nephropathy. Therefore, we decided to conduct two studies to examine the relationship of hANP levels to urinary albumin excretion and blood pressure. In a cross-sectional study, 83 randomly selected type 1 diabetic patients were investigated. 19 of the patients had increased urinary albumin excretion. 45 healthy volunteers served as controls. In a longitudinal study, 19 type 1 diabetic patients were examined for one year at monthly intervals. An increased risk of eventually developing diabetic nephropathy was identified in 7 out of these patients by repeatedly revealing increased urinary albumin excretion. On the average, hANP levels were increased in type 1 diabetic patients in comparison to controls (P < 0.001). In both studies, hANP levels were positively related (P < 0.05) to mean arterial blood pressure. There was no correlation between hANP levels and metabolic control. hANP levels lay within normal range irrespective of normal or elevated urinary albumin excretion provided that mean arterial blood pressure was normal. In the longitudinal study, increased urinary albumin and alpha-1-microglobulin excretion preceded the increase in both hANP levels and mean arterial blood pressure. Although hANP levels were evidently not related to the disease mechanisms of early diabetic nephropathy, it is tempting to speculate that hANP may contribute to the vicious circle connecting diabetic kidney disease to hypertension once that its levels are increased by elevated blood pressure. 相似文献

The authors report a retrospective series of 217 cases of autosomal dominant renal polycystic disease collected over a period of 30 years in the urology and nephrology departments of Nantes university hospital. They study the incidence of urological complications, observed in 87 patients (40%), consisting of calculi (15%), infection (22%, with 4 deaths), intracystic haemorrhages (3.5%) and urinary tract compression (2%). The diagnostic and therapeutic methods are presented and discussed. The results of renal transplantation are also analysed: 39 patients were transplanted, 72% retained a functioning kidney with a mean follow-up of 44.9 months (range: 12-108 months) and three patients died as a result of infectious complications. The 1-year and 3-year actuarial transplant survival rate of 92% was similar to that of renal transplantations performed for another form of renal disease. Preparation for renal transplantation remains an essential problem: the two major indications for pre-transplantation nephrectomy were the size of the kidneys and the presence of infection. 相似文献

Progression of nephropathy in long-term diabetics with proteinuria and effect of initial anti-hypertensive treatment 总被引:1,自引:0,他引:1
CE Mogensen 《Canadian Metallurgical Quarterly》1976,36(4):383-388
The rate of progression of nephropathy was studied in 6 young male diabetics with intermittent proteinuria (Albustix) and in 10 young male diabetics with constant proteinuria by measuring glomerular filtration rate (GFR), renal plasma flow (RPF), and urinary albumin excretion by exact techniques. Albumin excretion was elevated in both the recumbent and the erect position in patients with intermittent proteinuria. GFR and RPF were at the same level as in diabetics without proteinuria, and no deterioration in renal function was noted during a mean control period of 32 months. In the patients with constant proteinuria the fall rate during a mean period of 33.6 months for GFR and RPF was 0.91 ml/min/month +/- 0.68 (S.D.) and 4.38 ml/min/month +/- 3.23 (S.D.) respectively. Initial fall rate in GFR correlated well with long-term fall rate, both of which were studied in 7 patients. In the same patients there was a positive correlation between the fall rate in GFR and diastolic blood pressure as well as albumin clearance. In 8 patients with constant proteinuria and mean blood pressure of 159/101 mmHg, antihypertensive treatment was started with propranolol alone or combined with hydralazine and furosemide. During a treatment period of 47 days blood pressure was reduced to 143/93 mmHg, and in the same period urinary albumin excretion was reduced significantly from a mean value of 3547 mug/min to 2414 mug/min (P less than 0.01). Further control studies will clarify whether end-stage of renal insufficiency will be postponed by antihypertensive treatment. 相似文献

Renal vascular damage caused by arterial hypertension participates in the alterations to systemic vascular function and structure. Nephrosclerosis seems to run in parallel with systemic atherosclerosis, which accounts for the increased cardiovascular morbidity and mortality seen in hypertensive patients. Parameters indicating the existence of an alteration in renal function (increased serum creatinine, proteinuria and microalbuminuria) are independent predictors for an increased cardiovascular morbidity and mortality. Hence, parameters of renal function have to be considered in any stratification of cardiovascular risk in hypertensive patients. 相似文献

OBJECTIVE: We assessed the effects of atherosclerosis on the glomerular filtration rate (GFR) in patients with type 2 diabetes and who had micro- or normoalbuminuria. RESEARCH DESIGN AND METHODS: A total of 61 Japanese patients with type 2 diabetes were recruited from inpatients of Osaka City University Hospital. They ranged in age from 40 to 69 years (28 men and 33 women). Each subject collected a 24-h urine sample for quantitative analysis of albumin. Absence of albuminuria was defined as a urinary albumin excretion level of <30 mg/24 h (n = 36) and microalbuminuria as a level of 30-300 mg/24 h. The GFR was estimated using 99mTc diethylenetriamine pentaacetic renogram method. As indexes of atherosclerosis, we measured the intimal-medial thickness (IMT) and distensibility of the carotid artery using high-resolution B-mode ultrasonagraphy and an echo-tracking system. We measured the resistance index (RI) of the renal interlobar arteries by pulsed Doppler sonography. RESULTS: The clinical characteristics of type 2 diabetic patients with and without microalbuminuria did not differ except for duration of diabetes, which was longer in the patients with microalbuminuria. GFR also did not differ between the patients with and without microalbuminuria. GFR was significantly correlated with the patient's age (r = -0.256, P < 0.05), carotid IMT (r = -0.326, P < 0.05), carotid stiffness beta (r = -0.449, P < 0.001), and renal arterial RI (r = -0.365, P < 0.05). In multiple regression analysis, independent factors associated with GFR were carotid IMT (R2 = 0.108, P = 0.0102), carotid stiffness beta (R2 = 0.208, P = 0.0003), and renal artery RI (R2 = 0.130, P = 0.0043). CONCLUSIONS: The decline in GFR in type 2 diabetic patients in the early stages of nephropathy may be due in part to atherosclerosis. 相似文献

The aim of the study was to compare the diurnal pattern of blood pressure in diabetic patients with normal urinary protein excretion, microalbuminuria and end stage renal failure due to diabetic nephropathy and on continuous ambulatory peritoneál dialysis. An ABPM-oscillometric blood pressure monitor was used. Cholesterol, triglicerides, HDL and LDH1 cholesterole, apolipoprotein A1 and B, endogenous creatinine urinary protein and albumin excretion, beta-2-microglobulin were measured. The mean age and the mean diabetes duration of the 12 normoalbuminuric patients 38.3 and 16.5 years, of the 12 patients treated for renal failure with continuous ambulatory peritoneál dialysis 54.4 and 19.5 years. In the group with end stage renal failure and continuous ambulatory peritoneál dialysis, the mean nocturnal and diurnal systolic and diastolic blood pressure and the average arterial mean pressure was significantly higher than in the normal and microalbuminuric groups. In microalbuminuric and dialysed patients the physiological nocturnal decline of arterial blood pressure was absent. 24 hour blood pressure monitoring may accurately identify the early stage of diabetic nephropathy, and it might be valuable in the correction of antihypertensive treatment from the early to the final stages of diabetic nephropathy. 相似文献
