We report the case of a 50 year old lady with end stage renal disease, treated with colistin for catheter related blood stream infection and developed muscle weakness and parasthesia. Concomitant use of meropenem may have precipitated neurotoxicity of colistin. Conventional hemodialysis was effective in reversing her signs and symptoms. Clinicians should be aware of the risk of neurotoxicity while using colistin, especially after a loading dose in patients with renal impairment. According to our knowledge, this is the first report of conventional hemodialysis reversing the neurotoxic effects of colistin.","PeriodicalId":38952,"journal":{"name":"Open Urology and Nephrology Journal","volume":"8 1","pages":"53-55"},"PeriodicalIF":0.0,"publicationDate":"2015-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68066645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Jamboti","doi":"10.2174/1874303X01509010045","DOIUrl":"https://doi.org/10.2174/1874303X01509010045","url":null,"abstract":"Kidneys have a pivotal role in maintaining our homeostasis. Kidneys and heart work in tandem to maintain volume homeostasis. Heart failure impacts renal function in many ways including renal hypo perfusion but also due to increased venous pressure along with stimulation of various neuro-humoral responses. Renal failure induces cardiac damage and dysfunction by causing volume overload, inflammation and cardiomyocyte fibrosis. Concomitant comorbidities like Hypertension and Diabetes also play important role resulting in Cardiorenal Syndrome (CRS). Acute Dialysis Quality Initiative, 2007 recognized the bidirectional nature and different manifestations of CRS in acute and chronic settings. Diuretics are the most common drugs to treat the most common symptoms of CRS i.e., peripheral edema and pulmonary congestion. Diuretics could nevertheless contribute to worsening renal function (WRF). Initially it was accepted that WRF during the course of treatment of acute decompensated heart failure (ADHF) uniformly resulted in worse prognosis. However, in view of a few recent studies, the significance of WRF early in response to treatment of ADHF is being debated. The optimal dose and method of delivery of diuretics is still undecided. Isolated ultrafiltration does not improve renal function in patients with CRS despite the early promise. A large, multicentre trial ruled out any survival benefits with Recombinant Brain Natriuretic Peptide (Nesiritide). Despite good physiological basis and early promise with smaller studies, many drugs like Dobutamine, Rolofylline and Tolvaptan failed to show survival benefit in larger studies. However, two recent studies involving Relaxin and Neprilysin have shown good survival advantage. There had been little progress in treatment of CRS until studies involving Relaxin and Neprilysin inhibitor combination with ARB were published. There may after all, be a glimmer of hope in the field of CRS bogged by multiple negative studies.

The lower cost, and simplicity of the procedure makes it a particularly attractive option for the developing world which may lack even basic HD facilities, and patients continue to die for want of Renal Replacement Therapy (RRT). We present a review of the available literature about PD in the AKI setting with special reference to the developing world, including the procedure, costs, and effectiveness of the treatment.

The diagnosis of definite APS requires both clinical and laboratory criterion as established by the working group of the International Congress on Antiphospholipid Antibodies (based on expert opinion). Since thrombosis and pregnancy loss are common in the general population, and antiphospholipid antibodies (aPL) occurs in a small percentage of the healthy public, it is important to demonstrate antibody persistence in patients who have the proper clinical indications in order to avoid misdiagnosis. Unfortunately, laboratory testing in this area lacks standardization, resulting in wide inter-laboratory variance. However, due to the commercialization of tests and automation, inter-laboratory variance has improved. Data on several new non-criterion tests suggest that they may improve the specificity or risk stratification for thrombosis. A new guidance document on aPL testing strives to achieve better consistency, but much work remains to be done in the area of standardization.","PeriodicalId":38952,"journal":{"name":"Open Urology and Nephrology Journal","volume":"8 1","pages":"18-21"},"PeriodicalIF":0.0,"publicationDate":"2015-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68066999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients may present with recurrent thrombosis, obstetric morbidity, cardiac valvular lesions, thrombocytopenia, skin lesions, renal or neurologic abnormalities. We provide a comprehensive review of these diverse clinical features except renal and obstetric complications. Treatment of APS can be challenging as one tries to balance the benefit of anticoagulation therapy in this hypercoagulable state while minimizing the risk of bleeding. We discuss the various therapeutic options including the role of aspirin, warfarin, low molecular weight heparin, new direct thrombin inhibitors, hydroxychloroquine, intravenous gamma globulin, rituximab and others. Lower risk APS patients (i.e. first venous thrombosis) should receive warfarin with a target INR of 2.0-3.0. Higher risk patients (i.e. arterial thrombosis or recurrent venous events) have a target INR of >3.0. Currently, warfarin remains the mainstay in treatment of APS. Because of lack of adequate data, the newer oral direct inhibitors should be considered only when there is a known allergy/ intolerance or poor control with warfarin. Additional vascular and thrombotic risk factors should be aggressively reduced. Further studies involving large number of APS patients, diagnosed according to accepted criteria, are needed to better define the role of newer anticoagulants and other novel therapies.","PeriodicalId":38952,"journal":{"name":"Open Urology and Nephrology Journal","volume":"8 1","pages":"27-38"},"PeriodicalIF":0.0,"publicationDate":"2015-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68066522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
