We present a case of amiodarone pulmonary toxicity (APT) in a patient treated with amiodarone and everolimus. A 57-year-old Caucasian male, under treatment with both everolimus (for 3 years) and amiodarone (for 2 months), presented with fever, dyspnoea and a negative chest X-ray after his second kidney transplant with suboptimal serum creatinine (3 mg/dl). A non-contrastive high-resolution CT scan showed bilateral interstitial lung disease with an associated reduction in carbon monoxide diffusing capacity. Bronchoalveolar lavage (BAL) was negative for an infection, but BAL cytology was suitable for APT (50% of 'foamy' macrophages). A complete recovery was achieved after amiodarone interruption and an oral steroid therapy increase. Everolimus was continued. His kidney function remained unchanged in the upcoming months. In conclusion, we suggest a possible synergistic effect between m-TORi and amiodarone. Furthermore, we propose a diagnostic algorithm that can be used as a surveillance tool to identify a potential initial lung damage in patients treated with 1 or more pneumotoxic drugs. </p>","PeriodicalId":89663,"journal":{"name":"Case reports in nephrology and urology","volume":"4 1","pages":"75-81"},"PeriodicalIF":0.0,"publicationDate":"2014-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000362361","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32358327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, most glomerulonephropathies associated with TA show the histological feature of mesangial proliferation. Membranous glomerulonephropathy (MG) is a form of glomerulonephropathy in which the mesangial proliferation is not conspicuous and its association with TA is extremely rare. A 54-year-old man was referred to our hospital due to progressive edema in the lower limbs and nephrotic range proteinuria. Five years previously, he underwent percutaneous angioplasty for left subclavian artery stenosis. Kidney biopsy revealed stage II MG. General examination including enhanced CT scan confirmed the presence of TA. He started oral prednisolone therapy at a dose of 40 mg daily. The C-reactive protein level normalized 7 days after the prednisolone therapy. Three months later, proteinuria had remitted. Though the true relationship between MG and TA was not revealed in present case, considering the fact that complete remission of nephrotic syndrome occurred following the improvement of C-reactive protein level in response to steroid therapy, TA might be the secondary cause of MG. To our best knowledge, only two case reports described the association of MG and TA previously. Those two patients, however, also demonstrated the feature of systemic lupus erythematosus in addition to TA. This is the first case report that describes a patient who presented as MG associated with TA, but not complicated by systemic lupus erythematosus. </p>","PeriodicalId":89663,"journal":{"name":"Case reports in nephrology and urology","volume":"4 1","pages":"60-9"},"PeriodicalIF":0.0,"publicationDate":"2014-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000360850","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32358326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the optimal, standardized approach to the prophylaxis and management of thromboembolic complications associated with NS has not been established, anticoagulation with heparin and subsequent warfarin is the de facto standard of treatment. Dabigatran, a novel direct thrombin inhibitor, has become a substitute for warfarin and heparin for many indications, including the prophylaxis of stroke associated with nonvalvular atrial fibrillation and postoperative thromboprophylaxis in orthopedic patients. We report a 35-year-old male with NS due to membranous nephropathy (MN) that presented with carotid thromboembolism. Because the patient developed drug-induced hepatitis due to warfarin, we attempted treatment with dabigatran and were successful in continuing the medication without any complications. We also reviewed the literature on stroke associated with NS. Twenty-one prior cases have been reported, and the review of these cases revealed some interesting points. The age of onset ranged from 19 to 59 years. Most of the reported cases sustained a stroke at earlier ages than patients with atherosclerosis and atrial fibrillation, which suggests that NS may independently predispose individuals to arterial and venous thromboses. MN was the most common underlying pathology. Given that a standardized approach to the prophylaxis and management of thrombotic complications associated with NS has not been established, our experience suggests that dabigatran is a valid new treatment option for thrombotic complications of NS. </p>","PeriodicalId":89663,"journal":{"name":"Case reports in nephrology and urology","volume":"4 1","pages":"42-52"},"PeriodicalIF":0.0,"publicationDate":"2014-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000362162","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32320747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
