We report mefenamic acid-induced non-oliguric renal failure and severe neutropenia occurring simultaneously in two elderly females. The neutropenia was due to maturation arrest of the myeloid series in one patient. Both patients were also hypothyroid, but it is not clear whether this was a predisposing factor to the development of these adverse reactions. However, it would seem prudent not to use mefenamic acid in hypothyroid patients until the hypothyroidism has been corrected. 相似文献

A 52 year old man developed bullous pemphigoid, Coombs' positive haemolytic anaemia and diarrhoea related to the use of mefenamic acid. Clinical manifestation of the bullous pemphigoid, haemolytic anaemia and diarrhoea resolved following discontinuation of the mefenamic acid. Mefenamic acid should be added to the list of agents that are known to induce bullous pemphigoid. 相似文献

目的探讨建立马兜铃酸引起的大鼠慢性肾间质纤维化动物模型.方法将雌性wistar大鼠分为马兜铃酸组与对照组.马兜铃酸组大鼠腹膜内注射马兜铃酸5mg@kg-1@d-1共16周,开始用药后8、12、16、20、24周分别处死6只大鼠.对照组大鼠(5只)腹膜内注射生理盐水2ml/d,共16周,24周时处死.两组动物处死时分别留取血、尿、肾组织标本,分别作生化、病理(光镜,免疫荧光,电镜)等方面的检查及应用电脑软件测定肾小管-间质面积.结果马兜铃酸组大鼠用药后16、20、24周体重明显低于对照组;用药后16周血尿素氮、血清肌酐明显高于对照组,24周时肾功能损伤进一步加重.光镜检查可见马兜铃酸组大鼠有明显肾小管-间质损伤,16周时肾小管面积明显增加,管腔面积明显小于对照组;24周时出现明显肾小管萎缩,肾小管面积明显缩小,而肾间质面积明显增加,肾间质呈多灶性纤维化.电镜检查16周时肾小管上皮细胞胞质内初级溶酶体、次级溶酶体明显增加,部分肾小管上皮细胞刷状缘消失;20、24周时可见胞质内次级溶酶体和髓样小体堆积.结论建立了慢性马兜铃酸肾病动物模型.马兜铃酸具有慢性肾毒性作用,可引起大鼠慢性肾间质纤维化. 相似文献

A case of acute oliguric renal failure following gentamicin and linocomycin therapy is described. Renal biopsy showed an acute interstitial nephritis. This was associated with high serum gentamicin levels and the later development of ototoxicity. Withdrawal of antibiotics and conservative measures was followed by rapid recovery of renal function. Attention is drawn to the association between gentamicin and lincomycin therapy and the development of an acute interstitial nephritis. 相似文献

Objective: To explore the protective effect of Baoyuan Qiangshen Capsule No. II (BYQS) and its mechanism in treating chronic renal failure (CRF).Methods: Sixty CRF patients were divided into 2 groups randomly, the treated group used BYQS combined with Lotensin and the control group administered with essential amino acid combined with Lotensin. Changes of renal functions and tubular labelled proteins were observed.Results: The markedly effective rate and total effective rate of the treated group were 63.3% and 93.3% respectively, and those of the control group were 30.0% and 56.7% respectively, the effect of the treated group was obviously better than that of the control group (P < 0.01). In the treated group after medication, blood urea nitrogen, serum creatinine and clearance rate of creatinine were improved significantly (P < 0.01), while Tamm-Horfau protein increased significantly (P < 0.01).Conclusion: BYQS could alleviate tubular interstitial injury significantly so as to improve the renal function and enhance the effective rate in treating CRF. 相似文献

Acute interstitial nephritis secondary to esomeprazole 总被引:2,自引:0,他引:2

Between January 1979 and June 1985, 10 patients with acute allergic interstitial nephritis were seen in a clinical nephrology service at a large regional hospital. The onset of renal failure was temporally related to the use of a drug: a nonsteroidal anti-inflammatory agent (NSAID) (in four patients), cimetidine (in three), antibiotics (in two) or allopurinol (in one). The onset of renal failure was acute in three patients and insidious in seven. Two patients also exhibited marked proteinuria. Clinical features such as fever, rash, hematuria, pyuria with or without eosinophiluria, and mild to marked proteinuria had led to suspicion of the disease. The diagnosis was confirmed by renal biopsy findings of inflammatory cells, predominantly lymphocytes, plasma cells and eosinophils. Three patients required hemodialysis; two of them received steroids as well. Steroid therapy was also used in two patients with NSAID-induced proteinuria. Renal function improved in nine patients by 35 days, but one patient continued to have slow but progressive deterioration of renal function. Acute interstitial nephritis can be distinguished from other forms of acute renal failure by heavy renal uptake of gallium 67, maximal 48 hours or more after injection. The improvement in renal function after discontinuation of the implicated drug, the characteristic histopathological findings of allergic interstitial nephritis, and the presence of eosinophils and sometimes IgE in the blood suggest a hypersensitivity reaction. 相似文献
