Hypertension and nephrology - 2011;15(05)

[Background: Percutaneous renal biopsy is an essential tool in diagnosis and prognosis of renal diseases. It is well-known that this method has potential complications. The connection between complication occurrence related to renal biopsies and histological diagnoses of the biopsy specimen was analyzed in the present study. We also analyzed the distribution of diagnoses in our population. Methods: In this retrospective survey, 353 patients undergoing renal biopsy was studied. Biopsies were performed after marking the site of puncture with ultrasound imaging. Influence of diagnoses and clinical parameters on complications was evaluated. Results: We found a complication rate of 44.5%. In patients with diabetic nephropathy (likelihood ratio (LR) 0.44) or acute tubular necrosis (LR 0.38) a significantly lower rate of complications was found, while patients with thin basement membrane syndrome had more than 6-fold higher risk for evolvement of intrarenal haemorrhage. Patients with acute interstitial nephritis (LR 3.18) or vasculitis (LR 2.88) have a more than 2-fold risk for arteriovenous shunts while in patients with severe arteriosclerosis the occurrence of this complication was lower (LR 0.46). In rapidly progressive glomerulonephritis, arteriovenous shunts evolved also in a significantly higher rate. Conclusion: Patients with vasculitis, rapidly progressive glomerulonephritis, thin basement membrane syndrome or acute interstitial nephritis should be monitored more carefully after renal biopsy due to the significantly higher risk for complications. ]

[Association of body composition and mortality in patients on maintenance dialysis and on waitlist and after kidney transplantation]

UJSZÁSZI Ákos, KALANTAR-ZADEH Kamyar, MOLNÁR Miklós Zsolt

[Overweight [body mass index (BMI) = 25-30 kg/m2] and obesity (BMI ≥30 kg/m2) are epidemic in both developed and developing countries. Obesity has been recognized as risk factor for the development and progression of chronic kidney disease and is associated with increased cardiovascular risk and poor survival. Almost 2/3 of maintenance hemodialysis patients die within five years of commencing dialysis treatment. Although patients on the waitlist having less severe comorbidities than their non-listed counterparts, the death rate remains high while it can take years for an organ donation. In patients with end stage renal disease (ESRD) undergoing maintenance hemodialysis an “obesity paradox” has been consistently reported, i.e., a high BMI is incrementally associated with better survival. Overweight and obesity are highly prevalent in patients at the time of kidney transplantation. Indeed, most transplant centers in US may suspend wait-listing of obese patients with a BMI above 30 or 35 kg/m2 and refer them for weight reduction procedures such as bariatric surgery as a contingency for the transplant surgery. The effect of pre- and post-transplant obesity in kidney transplanted patients on long-term graft and patient survival has not been well established. We have reviewed and summarized salient recent data pertaining to body composition and clinical outcomes about the association of survival and body composition in transplant-waitlisted dialysis patients and kidney transplanted recipients. ]

[Antihypertensive therapy in patients with COPD - the significance of nebivolol]

FARSANG Csaba

[The occurrence of hypertension associated with chronic obstructive pulmonary disease (COPD) is increasing. Recognising COPD is important in order to choose the appropriate antihypertensive drugs. Anti-hypertensive drugs that can be used to treat patients with hypertension and COPD include diuretics, ACE-inhibitors, angioten-sine receptor blockers (AT1 receptor antagonists) and calcium antagonists, as well as cardioselective beta blockers, as these drugs decrease total and cardiovascular mortality. Of these agents, the importance of the most cardioselective one, nebivolol should be stressed, as this drug has no clinically significant effect on parameters of respiratory function, and, through its additional effects (namely by increasing the synthesis of NO), it has a beneficial effect on COPD-related deterioration of respiratory functions, haemodynamic alterations (cor pulmonale) and local factors that participate in the respiratory inflammation and endothelial dysfunction.]

[Genetics of isolated steroid-resistant nephrotic syndrome - results of the two decades around the turn of the millennium]

TORY Kálmán, KERTI Andrea, REUSZ György

[Childhood steroid-resistant nephrotic syndrome (SRNS) is a devastating clinical condition which progresses to end-stage renal disease in 30-40% of the cases after a follow up of 10 years. Based on its etiology, two forms can be distinguished, an immune and a genetic form. During the last two decades, mutations of ten genes - encoding mainly podocyte proteins - were identified in the latter group. As the treatment in the immune and genetic forms are different, and only the identification of the causative mutation can reliably distinguish them, it is important to be familiarized with the genotype-phenotype correlations. The aim of the present review is to summarize our current knowledge on the phenotypes linked to the identified genes.]

[Perioperative management of patients taking new oral anticoagulants - dabigatran in focus]

MÁRK László

[Appearance of new oral anticoagulants (NOAC) on the market requires a basically new approach from the doctors compared to vitamin K antagonists (VKA), the only oral anticoagulants used for several decades. These new drugs are at least as effective in the prevention of thrombotic events as the old ones and have the advantage that no regular laboratory monitoring is needed. Compared to the VKA a different management is required also in the perioperative care of patients taking NOAC. There is no need for bridge therapy, i.e. low-molecular-weight heparin (LMWH). The smaller surgical procedures can be performed 24 hours after the last dose of NOAC if it is administered once a day or 12 hours in case of agents administered twice a day. When a large surgical procedure is planned the drug should be stopped 24-96 hours before. The therapy should be resumed 6-8 hours after the procedure in low, 48-72 hours later in high bleeding risk cases. In a Canadian prospective study a protocol was used in which the stopping and resumption of dabigatran was recommended based on the bleeding risk and its half-life depending on the renal function. In 541 surgeries (60% with standard, 40% with increased bleeding risk) the occurrence of serious bleeding events was 1.8%, that of minor bleedings 5.2%. During the study one thrombotic event (TIA) occurred (0.2%). At the end of the article the author also makes a recommendation for stopping and resuming dabigatran therapy in case of tooth extraction, endoscopic biopsy and cholecystectomy.]

[Contact lens wear ]

TAPASZTÓ Beáta

[The improvement of contact lens materials and types have made it possible to use contact lenses for visual rehabilitation besides optical and cosmetic use, The high oxygen permeability of contact lenses have extended the age limits for contact lens wear and encouraged clinicians to use them for therapeutic purposes, especially for pain relief and aiding cornea epithelialisation. Con­tact lenses can be worn safely for years if rules of hygiene are followed. Their use is most frequently abandoned because of contact lens related dry eye. Despite the high oxigen permeability, their prolonged wear increases the risk of inflammation.]

[Complications of wearing contact lenses]

MÉSZÁROSNÉ PINTÉR Katalin

[Aim of the study: The author seeks to identify the reasons why contact lenses can cause wearers to develop inflammation of the cornea. She also examines whether the development of this severe condition can be avoided. Sample and method: The study was conducted among contact lens-wearing inpatients at the Ophthalmology Department of the Szent Pantaleon Hospital and Clinic. A questionnaire designed by the author, consisting of closed-ended questions, was distributed to 18 patients. Results: All 18 of the patients used soft, monthly-replacement contact lenses. Ten persons wore the lenses for two weeks longer, and five persons for one week longer than prescribed. Five persons neglected to wash their hands before inserting and removing the lenses. Five persons were not in the habit of cleaning contaminants from the lens, and seven persons did not use fresh storage solution every day. Four persons used tap water for the care of the lenses. Five persons did not remove the lenses at night, and four inserted the lenses into red, inflamed eyes. With the exception of one person they did not take a break from wearing the lenses, and three persons possessed spectacles. Fourteen persons were not satisfied with the information received from the optician. Conclusions: All of the changes were due to bacterial complications that were attributable to unsatisfactory cleaning of the contact lenses. ]

[Complications after subtotal extirpation of the esophagus and the radiological aspects of their treatment]

VÁGÓ Andrea, LUKOVICH Péter, FARKAS Szabolcs, KISS Katalin, KUPCSULIK Péter

[INTRODUCTION - Complications after subtotal esophageal extirpation (for eg.: insufficiency of anastomosis, stricture, etc.) and their treatment have special radiological considerations. Surgical departments and their radiologists meet early complications. But, all other radiological departments can face late complications, so the knowledge of these is important for all radiologists. PATIENT AND METHODS - 58 subtotal esophageal extirpations were performed in the last 5 years in the 1st Department of Surgery, Semmelweis University, Budapest. All postoperative radiological examinations were undertaken by the Department of Diagnostic Radiology and Oncotherapy. Most plain chest X-rays and swallowing examinations were made per-os with non ionic water soluble, low osmolarity contrast media on the 7th postoperative day. Further examinations were performed only if needed clinically. RESULTS - The complications were categorized as early and late. Early complications were aspiration, anastomosis insufficiency (31% of cases). Nine cases had self-dilating stents placed because of suture insufficiency. Further complications were noted following stenting (eg.: occlusion, dislocation of stent, closure of stent because of granulation tissues). Amongst late complications, stomach dilatation caused by pylorus-spasm (1 case), stricture of anastomosis (14 cases) and ’too-long’ esophageal stump (3 cases) were seen. CONCLUSION - Conventional radiology has a major role in diagnostics and treatment of complications of esophageal extirpation. Dynamic radiological examination and team work are required between the radiologist and surgeon. Also, it is crucial to cultivate good cooperation in cases of stent implantation, as contrary to the published literature, we find it better to have stents placed under flouroscopy rather than endoscopically.]

[The treatment of bleeding complications associated with anticoagulant therapy]

SCHLAMMADINGER Ágota

[The last few years have seen an increasingly widespread use of anticoagulant treatment. Not only is it applied in a wider range of diseases, but the duration of the treatment has also become longer on the basis of recent recommendations. Beside the traditional anticoagulant agents, coumarin and heparin, a new generation of anticoagulants has emerged in the past few years. These can be administered orally in a fixed dose, which will make anticoagulant treatment available for an even wider patient population. However, the more widespread use of anticoagulants will result in the growing occurrence of their most threatening adverse effect, bleeding. We summarize the treatment options for the bleeding complications in connection with the administration of the currently used anticoagulants and the available methods of their reversal.]
