目的 探讨肾小球肾炎合并急性间质性肾炎(AIN)患者的临床和病理特点。 方法 回顾性分析21例经肾活检证实的肾小球肾炎合并AIN患者的资料,以同期无肾小球疾病的AIN患者 35例作为对照。 结果 肾小球肾炎合并AIN占同期AIN的37.5%。β内酰胺类抗生素、中药是引起AIN的主要病因。76.2%的患者就诊原因为发现血肌酐升高。肾组织学检查同时存在肾小球肾炎和AIN的病理改变,肾间质与肾小球病变程度不平行,前者普遍重于肾小球损害,肾间质中嗜酸性粒细胞对诊断有提示价值。随访中,64.7%的患者肾功能最终恢复正常或基线水平,中位恢复时间为150 d(单纯AIN组为60 d),两组患者在2年内肾功能恢复情况方面无明显差异。 结论 肾小球肾炎合并AIN的患者临床表现不典型,AIN的症状易被肾小球肾炎掩盖。肾活检对诊断和鉴别有重要价值。早期诊治的患者预后较好。 相似文献

ObjectiveDrug-induced acute interstitial nephritis (DAIN) is often associated with improved outcomes, whereas some patients may still progress to chronic kidney disease (CKD). The aim of this study was to evaluate the prognosis of patients with severe DAIN requiring renal replacement therapy (RRT) at baseline, and to explore the risk factors of progression to CKD.MethodsWe performed a retrospective study of patients with severe DAIN confirmed by renal biopsies in our center over a 10 years period, all the patients received RRT at presentation. The clinical and pathological characteristics at baseline were recorded, and the outcomes (renal function recovered or progressed to CKD) during follow-ups were also evaluated. Univariate and multivariate logistic regression analysis were performed to identify the independent risk factors of progression to CKD.ResultsSeventy-two patients who met the inclusion criteria were enrolled, 13 patients (18.0%) progressed to CKD (GFR < 60 ml/min/1.73 m2) after at least 6 months of follow-up, the remaining 59 patients achieved a favorable renal function recovery. Compared with patients who achieved renal function recovery (recovery group), the patients progressed to CKD (progression group) were older and had longer interval from symptom onset to treatment with steroids. The peak serum cystatin C concentration was higher in progression group than recovery group. Higher score of interstitial fibrosis/tubular atrophy (IFTA) and more interstitial inflammatory cells infiltration were detected in renal tissue in progression group. According to multivariable analysis, higher peak cystatin C concentration (OR = 2.443, 95% CI 1.257, 4.746, p = 0.008), longer interval to treatment with corticosteroids (OR = 1.183, 95% CI 1.035, 1.352, p = 0.014) were independent risk factors of progression to CKD. The cutoff value of cystatin C concentration was 4.34 mg/L, at which the sensitivity and specificity were 76.9% and 89.3%, respectively; the cutoff value of interval to treatment with corticosteroids was 22.5 days, at which the sensitivity and specificity were 81.8% and 79.5%, respectively.ConclusionRenal function was reversible in majority of patients with severe DAIN requiring RRT when early identification and treatment. Higher peak cystatin C concentration and longer interval to treatment with corticosteroids associated with worse renal prognosis. 相似文献

Proton pump inhibitors and acute interstitial nephritis: report and analysis of 15 cases 总被引:2,自引:0,他引:2
Simpson IJ Marshall MR Pilmore H Manley P Williams L Thein H Voss D 《Nephrology (Carlton, Vic.)》2006,11(5):381-385
AIM: Although proton pump inhibitors (PPI) are usually safe and effective therapeutic agents, serious adverse effects can occur. The aim of the present study was to report and analyse the clinical features of 15 patients with acute interstitial nephritis (AIN) and acute renal failure from PPI that were referred to renal services in Auckland over a period of 3 years. METHODS: The clinical presentation, therapeutic drugs, demographic details and renal outcome of the patients were considered. The population at risk and total PPI exposure were able to be defined. The diagnosis of AIN was made by renal biopsy in 12 cases. In all patients, the time-course of drug exposure and improvement of renal function on withdrawal suggested PPI were causal. RESULTS: The median patient age was 78 years. The mean baseline serum creatinine level was 83 micromol/L, peak level 392 micromol/L, and recovery level 139 micromol/L. The erythrocyte sedimentation rate (ESR) and C-reactive protein were elevated at the time of diagnosis in the 11 and 12 patients, respectively, where this information was collected (ESR mean 85 mm/h, and C-reactive protein mean 81 mg/L). AIN occurred at 8 per 100 000 patient years (95% confidence level 2.6-18.7 per 100 000 patient years). Although four patients presented with an acute systemic allergic reaction, 11 were asymptomatic with an insidious development of renal failure. CONCLUSION: PPI are now the most commonly identified cause of AIN in the Auckland area. Recovery occurs after withdrawal of the drug but is often incomplete. Early diagnosis may be facilitated by clinician awareness of the insidious onset of renal failure, and an elevated erythrocyte sedimentation rate and C-reactive protein. 相似文献

Rabeprazole-induced acute interstitial nephritis 总被引:3,自引:0,他引:3
Acute interstitial nephritis is an uncommon but important cause of acute renal failure. Proton pump inhibitors are now thought to be the most common class of drugs implicated in drug-induced acute interstitial nephritis. This is the first reported case of rabeprazole-induced acute interstitial nephritis. 相似文献

Phenazopyridine is a urinary analgesic; commonly seen side-effects of this drug include, orange discoloration of urine, methemoglobinemia, yellowish skin discoloration, hepatitis and acute renal failure. Various case reports with phenazopyridine associated acute renal failure secondary to acute tubular necrosis have been reported in the literature. Acute kidney injury in these patients is caused by either direct injury to renal tubular epithelial cells or secondary to pigment induced nephropathy from hemolytic anemia. Hypoxic injury from phenazopyridine-induced methemoglobinemia has been well documented. We report a case of biopsy proven acute interstitial nephritis, associated with therapeutic doses of phenazopyridine without any evidence of methemoglobinemia or other mechanism of renal injury. Clinicians should be aware of the toxicity of this commonly used drug and should look closely for signs of renal insufficiency. Identifying and stopping the offending medication stays as the first step, but recent studies indicate that early steroid administration improves renal recovery, as well as decreasing the risk of progression to chronic kidney disease with fibrosis and consequent permanent renal damage. 相似文献

The introduction of Bruton''s tyrosine kinase inhibitor ibrutinib has made a significant progress in the treatment of chronic lymphocytic leukemia and other B-cell malignancies. Due to the reduction of cytokine release, it is effective in chronic graft-versus-host disease, and its use has also been suggested in autoimmune diseases and in prevention of COVID-19-associated lung damage. Despite this effect on the immune response, we report a severe hypersensitivity reaction in a 76-year-old male patient diagnosed with prolymphocytic leukemia. Four weeks after the ibrutinib start, non-oliguric acute kidney injury with proteinuria and microscopic hematuria developed and that was accompanied by lower limb purpuras and paresthesia. Renal biopsy revealed acute interstitial nephritis. Employing 1 mg/kg methylprednisolone administration, serum creatinine decreased from 365 μmol/L to 125 μmol/L at 11 days and the proteinuria-hematuria as well as the purpura, paresthesia resolved. Three months later at stabile eGFR of 56 ml/min/1.73 m2 methylprednisolone was withdrawn and a rituximab-venetoclax treatment was initiated without side effects. We conclude that despite the beneficial effect on cytokines response in Th1 direction, ibrutinib can cause acute interstitial nephritis. Early detection, discontinuation of ibrutinib, glucocorticoid administration may help to better preserve renal function, thereby lowering the risk of potential subsequent kidney injury. 相似文献

A syndrome of acute interstitial nephritis (AIN) and anterior uveitis is described in two children and the literature is reviewed. These disorders appear to improve, in uncontrolled studies, with systemic and topical ophthalmic corticosteroid treatment. Although the renal and ocular prognoses appear good, it is important to recotnize that patients with AIN are at risk for uveitis and if present, consultation with an ophthalmologist is recommended. 相似文献

Antibiotic-induced recurring interstitial nephritis 总被引:1,自引:0,他引:1
Acute interstitial nephritis (AIN) is often induced by drug therapy and accounts for 1%–3% of adult cases of renal failure.
A 13-year-old white female with cystic fibrosis developed two episodes of biopsy proven AIN following antibiotic use over
a 5-year period. The first episode resolved with pulse steroid therapy and the second resolved without intervention. Steroid
therapy may play a role in aborting subsequent AIN attacks.
