Title: Treatment of chronic total venous occlusions in patients with end stage renal disease
Speaker
Biography:

Edwin Rodríguez-Cruz has completed Doctorate degree from the San Juan Bautista School of Medicine, PR. He specializes in Internal Medicine & Pediatrics. He completed Pediatric Cardiology fellowship and sub-fellowship in Interventional Cardiology from the Children's Hospital of Michigan. Currently, he is the Director of Cardiology of the San Jorge Children's Hospital, and Associate Professor of Medicine and Pediatrics at the San Juan Bautista School of Medicine, PR, USA. He has published over 20 articles in peer review journals and many specialty opinions by editors' request. His interests are in the areas of heart failure, structural heart diseases, and difficult venous accesses. He has special interest in chronic total venous occlusions (CTVO).

Abstract:

Chronic Total Venous Occlusions (CTVO) are one of the many challenges physicians have to confront in the daily treatment of patients with End Stage Renal Disease (ESRD). Even in cases where an arteriovenous fistula is present, central venous occlusions may occur and be a hassle for the culmination of therapy by hemodialysis. A total of 79 patients with CTVO has undergone re-opening of the vessels in our institution, of those 29 had ESRD. The 29 patients comprised: 17 females and 12 males. The mean age was 17 years (8- 76 years). One female patient was lost to follow up. The time at presentation was a mean of 4 months (3-9 months). The majority of patients had swelling of one extremity or face, and difficulty with dialysis upon presentation. A total of 48 percutaneous interventions were carried out. In all the patients, we were able to open the anomalous vessel. Twelve (12) patients required more than 1 intervention to maintain patency of their diseased vessel. The shortest time to need another procedure was 1 month, and the longest 25 months. Stents were implanted in 11 patients with 2 requiring more than 1 stent in different occasions. Of the patients with only 1 procedure, the range without re-interventions is from 1 month to 5 years. The most commonly intervened vessels were central thoracic veins. With the application of simple methods of reopening the CTVO percutaneously, we have achieved a good medium term patency in patients with ESRD. With newer technologies however, possibly adapted from arterial interventions, the longevity of these accesses may be prolonged.

Biography:

B Balaji Kirushnan has completed his medical training in the year 2012. He has won the Apollo gold medal award in Internal Medicine during his post-graduation. He has been trained in various fields of Nephrology like acute renal failure, continuous renal replacement therapy, peritoneal dialysis and renal transplant. He has also been trained in renal histopathology and across the blood group renal transplantation. He has given various lectures to physicians to highlight the importance of referral to a Nephrologist. He is a member of Indian Society of Nephrology and Indian Society of Nephrology southern chapter. He has been certified by Royal College of Physicians, UK in Nephrology. He has a number of case reports to his publications. He has won accolades and is prized for poster presentations in various international and national conferences. A special interest in research has made him a part of the ongoing research in clinical trials in nutrition in haemodialysis and novel therapies of hepatitis C.

Abstract:

Chronic hepatitis C remains an important health problem in chronic kidney disease and is associated with reduced graft survival after renal transplantation. It is more common in developing countries and in haemodialysis centers, where there is a break in universal precautions during reuse of haemodialyzers.  Hepatitis C is also associated with increased rates of rejection, new onset diabetes mellitus and occurrence of de-novo glomerulonephritis after renal transplant. It is associated with fibrosing cholestatic hepatitis and extra hepatic complications like vasculitis. The recommended treatment in the post-transplant setting with interferon is only when the benefits of the treatment outweigh the risks.  Conventional interferon therapy in the post renal transplant scenario has been associated with increased rates of allograft rejection. Directly acting antivirals (DAA) could offer a new therapeutic armamentarium in post renal transplant recipients without precipitating rejection. Newer drugs like sofosbuvir, ledipasvir and daclatasvir have been used in hemodialysis and peritoneal dialysis patients to achieve a sustained virological response before renal transplant. The above strategy has shown better outcome in terms of patient tolerability of drugs and sustained remission rates of virological response after transplant.

After one-year Medical Training in Nahariya Medical Center, he moved to Rambam Medical Center for Residency & Specialization in Internal Medicine and subsequently sub-specialization in Nephrology and Hypertension. Since 2003, he serves as Director of the Department of Nephrology and Hypertension at Nazareth Hospital, Nazareth, Israel. He has received several awards for his research and clinical activity including Dangur Family Award from Bar Ilan University. He has over 30 original publications in peer review journals and text books. Besides his recent and past achievements in research, he had excellent achievements as a Lecturer, expressed by a wide variety of prizes that he received for (constantly) excellence in teaching including the best Bar Ilan Lecturer Award. He has extensive experience in Nephrology research. His main interest is anemia and the impact of carnitine on iron-induced oxidative stress in CKD patients. Over the last 10 years his group has been studying the pathophysiology of inflammation and oxidative stress following IV iron administration. In addition, his research focuses on contrast-induced nephropathy and novel therapeutic approaches to this common disease state. Finally, he studies the incidence of depression in ESRD patients on hemodialysis and peritoneal dialysis and the factors underlying this phenomenon. 

Abstract:

Background: Anemia is a common problem in CKD patients. It is attributed to decreased erythropoietin (EPO) production, low iron stores, and the chronic inflammatory milieu. Therefore, therapy includes not only recombinant EPO, but also irons replenishment. However, the latter induces oxidative stress as well as inflammation. Randomized, controlled studies suggested that L-carnitine supplementation might have positive effects on the response to EPO in long term hemodialysis patients. However, there is no evidence whether this approach is also beneficial in earlier-stage CKD patients. Thus, the present study examined whether L-carnitine prevents IVIR-induced oxidative stress and whether it improves response to EPO.

Aims: Our hypothesis is that: 1. Intravenous administration of iron (IVIR) to CKD patients at early stages of the diseases (Stage 2-4) provokes oxidative stress and inflammation; 2. Prophylactic L-carnitine supplementation could prevent the IVIR-induced oxidative stress and inflammatory responses in these patients.

Methods: The current study included 32 anemic CKD patients (stages 2-4) that were divided into 2 subgroups: Group of 16 patients was given a weekly IVIR (Sodium ferric gluconate, [125 mg/100 ml] for 12 weeks. Group 2: Sixteen patients received the same IVIR regimen but also carnitine (20 mg/kg, IV) was administered weekly 30 min prior to IVIR administration through the whole treatment period. Weekly blood samples were drawn before and after each IVIR for Hb, C-reactive protein (CRP), advanced oxidative protein products (AOPP), TBARS and neutrophil gelatinase-associated lipocalin (NGAL), in addition to routine complete blood count and biochemical analyses.

Results: Combined administration of IVIR and carnitine increased Hb more profoundly (+8%) than those treated with IVIR alone (+13%). While IVIR alone induced oxidative and inflammatory responses, patients who received carnitine did not exhibit these adverse effects, as was evident by abolishing IVIR-induced elevation in CRP, NGAL, AOPP, and TBARS.

Conclusion: Our finding demonstrated that co-administration of carnitine with IVIR preferentially attenuates the adverse consequences of IVIR, suggests a role for Carnitine therapy in these patients.

Abstract:

Protein energy wasting (PEW) affects morbidity and survival of patients on maintenance dialysis. Primary end point was to evaluate efficacy of proseventy on hypoalbuminemia over a period of 6 months (increase in serum albumin). Inclusion criteria: i) Serum albumin is <3.8 g/100 mL ii) patients on maintenance dialysis for at least 3 months. Exclusion criteria: No clinical PEW as per ISRNM criteria. Multicentric oral nutritional intervention study was performed on maintenance dialysis patients with established hypoalbuminemia (serum albumin <3.8 g/100 mL) and PEW as per ISRNM criteria. 36 patients were on peritoneal dialysis and 144 on hemodialysis. The study was approved by ethics committee. 180 patients (90 supplemented and 90 control) were randomly assigned 1:1 to standard treatment (control group) or standard treatment plus nutritional supplement (supplemented group) for 6 months. The renal specific protein powder supplement contained 70% soya protein. Control group were kept on 1.2 g/kg/d protein and 35 kcal/kg/d. Supplemented group received protein supplement daily in three divided doses of 10 g/dose. Patients were evaluated on 3 visits at months 0, 3 and 6. At each visit, nutritional status was assessed by SGA, 24 hour dietary recall and anthropometry, routine biochemical parameters. SF36 Quality of Life questionnaire pre/post intervention was used for assessment of efficacy of nutritional supplement. Three days dietary recall was maintained in food diaries. At inclusion, no difference in age, sex, SGA and routine biochemistry was observed. Control group, however, had significantly higher serum albumin (3.37±0.36 vs. 3.2±0.41 g/dL; p=0.013) and subscapular skinfold thickness (14±6.0 vs. 12.1 ±5.0 mm; p=0.032) than supplemented group. Out of 180 patients, 128 (89 in control and 39 in supplemented) completed the study. Compliance was assessed by counting empty tins returned by the patient. At visit 1, 2 and 3, there was significant difference in protein intake in supplemented and control groups (48.35±14.2 and 51.93±16.4; 65.15±21.86 and 63.49±19.4; and 67.05±20.7 and 65.36±19.1 g/day respectively). At visit 1, 2 and 3 in supplemented and control groups, there was significant difference in energy intake (1546.06±397.24 and 1607.41±396.72; 1774.73±535.9 and 1730.49±408.15; and 1891.31±490.65 and 1813.26±464.82 kcals/day). Though CRP levels were above normal in both the groups, they were significantly higher in controls compared to supplemented group (visit one 8.7±8.1 vs. 4.2±6.01 visit 3, 5.2±0.9 vs. 4.7±0.8 (p=0.016). At 3rd month, the serum albumin (3.4±0.43 vs. 3.3±0.48 g/dL) and illiac SFT (18.1±8.6 vs. 15.5±8.5 mm; p=0.043), increased significantly in the supplemented group. At six months in supplemented group serum albumin increased significantly (p=0.000) to 3.9±0.49 versus 3.3 ±0.51 in control group. Nutritional status as per SGA score improved in supplemented compared to controls. At 6 months, the biceps (13.0±7.1 vs. 9.1±6.0 mm), triceps (16.1±5.1 vs. 12.1±5.1 mm), subscapular skinfold (17.0±7.2 vs. 16.4±6.9 mm) and suprailliac skinfolds (18.1±8.7 vs. 16.8±8.7 mm) were significantly higher in supplemented group (p=0.000) compared to controls. Additional protein-rich renal specific nutritional supplement to standard nutritional counseling raised serum albumin and increased skinfold thickness in PEW patients undergoing dialysis.

Abstract:

Background: Osteodystrophy management includes a dietary phosphorus restriction, which limits protein intake, exacerbating the malnutrition-inflammation syndrome and mortality among hemodialysis patients.

Methods: A multi-center randomized controlled trial was conducted to test the hypothesis that intensive nutrition education focused on phosphorus-to-protein balance will improve patient outcomes. Six hemodialysis units were randomly assigned to the Trained Hospital Dietitian (THD) protocol (210 patients). Six others (184 patients) were divided equally according to the patients' dialysis shifts and were assigned to Dedicated Dietitian (DD) and Control protocols. Patients in the THD group received nutrition education from hospital dietitians who were trained by the study team on renal dietetics, but who had limited time for hemodialysis patients. Patients in the DD group received individualized nutritional education on dietary phosphorus and protein management for 6 months (2-hour/patient/month) from study renal dietitians. Patients in the control group continued receiving routine care from hospital dietitians who had limited time for these patients and were blinded to the study. Serum phosphorus (mmol/L), malnutrition-inflammation score (MIS), 8-domain health-related quality of life (HRQOL) index and length of hospital stay (LOS) were assessed at T0 (baseline), T1 (post-intervention) and T2 (post-6 month follow up).

Results: Only the DD protocol significantly improved serum phosphorus (T0:1.78±0.5, T1:1.63±0.46, T2:1.69±0.53) and 3 domains of the HRQOL index and maintained MIS at T1, but this protective effect resolved at T2. The LOS significantly dropped for all groups by T2.

Conclusion: The presence of competent renal dietitians fully dedicated to hemodialysis units was superior over the other protocols in improving patient outcomes.

Title: Concepts of wearable artificial kidney development
Speaker
Biography:

Nikolai A Bazaev has completed his PhD and currently works as a Senior Scientist in National Research University of Electronic Technology, Department of Biomedical Systems. He has published more than 10 papers in reputed journals. He is an actual member of ESAO since 2016, member of ERA-EDTA since 2017. He works on two scientific projects: Development of a wearable artificial kidney, and development of a noninvasive glucometer. 

Abstract:

The work is devoted to results of dialysis regeneration methods investigation. The aim of the work is to construct a wearable artificial kidney that carries out prolonged continuous peritoneal dialysis. The dialysis fluid is recirculated through an extracorporeal circuit, which undergoes regeneration. Several activated carbons and hemosorbents were evaluated as potential sorpiton material. Three methods of urea elimination were aprobated: Immobilized urease, electrooxidation and thermal degradation. As a result, a prototype of a wearable artificial kidney was assembled. Its regeneration unit is based on electrolysis and gives opportunity to reach the urea elimination rate up to 1.2 g/h; creatine and uric acid elimination rates both equals to 0.3 mg/h (in vitro experinents). Along with that it is possible to keep concentration of sodium, chlorine and calcium ions in the range of 10% deviation from the starting value. The prototype of WAK is designed as a backpack and weights about 3.5 kg. In vivo experiment showed that the prototype carries out its functions, gives opportunity to eliminate exeeded fluid from peritoneal cavity and doesn’t affect blood pH during dialysis.

Abstract:

Acute kidney injury is defined by an abrupt decrease in kidney function that includes, but is not limited to acute renal failure. It is a broad clinical syndrome encompassing various etiologies, including specific kidney diseases like acute interstitial, glomerular or vasculitic renal diseases; non-specific conditions like ischemia, toxic injury or extra-renal pathology as pre-renal azotemia, or post-renal obstructive nephropathy. Acute kidney injury is common, harmful and potentially treatable. Even a minor acute reduction in kidney function has an adverse prognosis. Kidney failure is defined as a GFR of 15 ml/min per 1.73 m2 body surface area, or requirement for renal replacement therapy. Acute kidney injury complicates 5-7% of acute care hospital admissions and upto 30% of admissions at intensive care unit, particularly in the setting of diarrheal illness, infectious diseases like malaria, leptospirosis and natural disasters such as earth quakes. Mortality due to AKI may exceed 50% in cases admitted in intensive care unit. It also increases the risk for development or worsening of chronic kidney disease. Acute kidney injury may be community acquired or hospital acquired. Common causes of community acquired syndrome includes volume depletion, adverse effects of medication and obstruction of the urinary tract and those in hospital acquired AKI are sepsis, major surgical procedures, critical illness involving heart and liver failure, administrations of intravenous contrast and nephrotoxic medications. Pre-renal azotemia is the most common cause of acute kidney injury and usually a result of renal hypoperfusion. It accounts for approximately 60 to 70% of the community acquired and 40% of the hospital acquired cases. The most common clinical conditions associated with pre-renal azotemia are hypovolemia, decreased cardiac output, advanced cirrhosis and medications that interfere with renal autoregulatory responses such as NSAIDS and inhibitors of angiotensin II. Early in the course of pre-renal acute kidney injury, the renal parenchyma remains intact because kidney hypoperfusion initiates a neurohormonal cascade that results in afferent arteriolar dilatation like myogenic reflex, prostaglandin mediated and efferent arteriolar constriction, angiotensin II mediated thereby maintaining glomerular filtration pressure closer to normal and thus prevents marked reduction in GFR if renal blood flow reduction is not excessive. Intrinsic azotemia is classified according to the primary histologic site of injury. Renal tubular epithelial cell injury, commonly termed acute tubular necrosis, occurs more commonly in the setting of ischemia, although renal tubules can also be affected by sepsis and toxins both endogenous and exogenous.

Abstract:

The reason of anaemia during chronic renal insufficiency is deficiency of erythropoietin (ESA). Risk factors for ESA resistance are absolute or functional iron deficiency, gastrointestinal blood loss, haemolysis, inflammation, infection, malignancy, folic acid and vitamin B12 deficiency, inadequate haemodialysis, hyperparathyroidisim, Angiotensin converting enzyme inhibitor, Angiotensin II receptor blocker, Anti-erythropoietin antibody and genetic polymorphism. We describe a case of 52 year old man who had a history of renal allograft failure. Three moons later he presented to the hospital with symptoms of severe anemia, hematuria, fever, exhaustion and fatigue. Due to deep anaemia, 5 times in 2 months (2U each time) erythrocyte replacement (ES) was performed. There was sensitivity in the graft site. Laboratory examinations were: Hb 5.4 gr/dl (13-17), albumin 2.2 gr/dl (3.5-5.2), ferritin >2000 ng/ml (30-100), transferrin saturate was calculated as 40%, vitamin B12 402 pg/ml (191-663), parathormon 630 pg/ml (15-65), C-reactive protein 117 mg/L (0-5), sedimentation 70 mm/hour. In the conducted peripheral spread, normochromic was compatible with normocytic anaemia. The patient was taking epoetin beta 150 Ü/kg vitamin D in treatment, upon no detection of reproduction in sent blood, urine and sputum cultures. Methylprednisolone (10 mg) was started with Graft intolerance syndrome (GIS) diagnosis. Patient did not have fever and did not need ES in his medical follow-ups. GIS was successfully treated with low dose steroids despite the suggestion of high dose steroids. After treatment, Hb level exceeded 12 gr/dl and he did not need erythropoetin.

Abstract:

Dialysis patients with uremic pruritus (UP) have a significantly higher risk of mortality and a poor quality of life. This study aimed to develop and validate a multidimensional scale assessing the UP: Uremic Pruritus in Dialysis Patients (UP-Dial). The development and validation of the UP-Dial instrument was conducted in four phases: (1) Item generation, (2) development of pilot questionnaire, (3) refinement with patient recruitment, and (4) psychometric validation. Participants completed the UP-Dial, the visual analogue scale (VAS) of UP, the Dermatology Life Quality Index (DLQI), the Kidney Disease Quality of Life-36 (KDQOL-36), the Pittsburgh Sleep Quality Index (PSQI), and the Beck Depression Inventory (BDI) during May 15, 2012 to November 30, 2015.  The 27-item pilot UP-Dial was generated with 168 participants. After factor analyses, the final 14-item UP-Dial encompassed three domains: Signs and symptoms, psychosocial, and sleep. Face and content validity were satisfied through the item generation process and review of experts. The psychometric analysis demonstrated that the UP-Dial had good convergent and discriminant validity. The UP-Dial was significantly correlated (Spearman rank correlation, [95% CI]) with the VAS-UP (0.76 [0.69 to 0.83]), DLQI (0.78 [0.71 to 0.85]), KDQOL-36 (-0.86 [-0.91 to -0.81]), PSQI (0.85 [0.80 to 0.89]), and BDI (0.70 [0.61 to 0.79]). The UP-Dial revealed excellent internal consistency (Cronbach’s α 0.90 [0.87 to 0.92]) and reproducibility (intraclass correlation 0.95 [0.90 to 0.98]). The UP-Dial is valid and reliable for assessing UP among dialysis patients. This questionnaire can be used to standardize the effects of intervention in comparative-effectiveness research.

Abstract:

Sepsis has been found to be a leading contributing factor in acute kidney injury (AKI) during critical illness. In patients with sepsis, prerenal factors significantly contribute to AKI. Despite optimal hemodynamic monitoring, rapid hemodynamic resuscitation and intravascular volume restoration, certain patients remain hypotensive. We examined the impact of hypotension on the evolution of AKI in septic patients. Therefore, we focused on the role of hypotension as the principal objective and examined: 1) The influence of hypotension during sepsis, 2) the influence of proven sepsis to failure and 3) the influence of hypotension on the evolution to failure. Patients were divided into four groups based on their RIFLE classification on the day of positive blood stream infection (BSI) detection. Between all groups, there was no difference in the delay of antibiotic treatment, episodes of septic shock or the total number of days in septic shock. In total, 75% of the study population evolved to AKI during their ICU stay and most patients evolved to failure. There was no significant difference between patients with Gram-positive or -negative infection in the occurrence of hypotension, the duration of hypotension or the number of periods of hypotension. After BSI, the probability for a patient to be in failure is significantly higher than before BSI (OR=1.94, p=0.0276). Patients have a significantly higher risk of evolving to failure if the duration of severe hypotension is longer (OR=1.02 for 10 minutes increase in duration of hypotension is, p=0.0472). In our population of septic patients, a cut-off of at least 51 minutes of severe hypotension (<65 mmHg (sens=0.55, spec=0.68)) or at least 5.5 periods of severe hypotension within 1 day was determined to identify patients with increased risk of evolving to failure. This study underscores the observation that low mean arterial pressure levels are associated with a higher incidence of AKI in septic patients.

Abstract:

Background & Aim: Transesophageal Doppler (TED)-guided intraoperative fluid therapy has shown to noninvasively optimize intravascular volume and reduce postoperative morbidity. The aim of this study was to compare the effects of Doppler-guided intraoperative fluid administration and central venous pressure (CVP)-guided fluid therapy on renal allograft outcome and postoperative complications.

 

Material & Methods: A prospective nonrandomized active controlled study was conducted on end-stage renal disease patients scheduled for living donor renal transplant surgery. 110 patients received intraoperative fluid guided by corrected flow time (FTc) and variation in stroke volume values obtained by continuous TED monitoring. Data of 104 patients in whom intraoperative fluid administration was guided by CVP values were retrospectively obtained for a control.

 

Results: The amount of intraoperative fluid given in the study group (12.20±2.24 ml/kg/h) was significantly lower than in the controls (22.21±4.67 ml/kg/h). The amount of colloid used was also significantly less and fewer recipients were seen to require colloid (69 vs. 85%). The mean arterial pressures were comparable throughout. CVP reached was 7.18±3.17 mmHg in the study group. It was significantly higher in the controls (13.42±3.12 mmHg). The postoperative graft function and rate of dysfunction were comparable. Side-effects like postoperative dyspnoea (4.8 vs. 0%) and tissue edema (9.6 vs. 2.7%) were higher in the controls.

 

Conclusion: FTc-guided intraoperative fluid therapy achieved the same rate of immediate graft function as CVP-guided fluid therapy but used a significantly less amount of fluid. The incidence of postoperative complications related to fluid overload was also reduced. The use of TED may replace invasive central line insertions in the future.

Abstract:

The study of chloride channels of membranes has seen an explosion of interest recently and exciting developments have sparked renewed interest in this field. In contrast, despite the prominent concentration of chloride in serum, textbooks in general do not allocate chapters exclusively on chloride or hypochloremia and hyperchloremia. Although chloride was the first electrolyte to be easily measured, its importance always has been overshadowed by other major serum electrolytes, seemingly serving as a sort of appendix of sodium or potassium or just a stand-in for bicarbonate. Chloride is responsible for about 100 of the 300 mosm/L of extracellular fluid tonicity and for two-thirds of all negative charges in plasma. To maintain acid–base balance, chloride has an inverse relationship with bicarbonate, which is part of the major chemical buffering system responsible for maintaining a normal pH when bicarbonate is lost by the kidneys or the intestines. Chloride and bicarbonate shift into and out of erythrocytes and tubuli to maintain acid–base balance. Because of its high concentration, chloride is the most important anion to maintain the balance of extracellular cations and anions to ensure electrical neutrality as the number of anions and cations in body fluids must always be equal. The high intracellular [Cl] in erythrocytes allows chloride to move in and out of the red blood cells very effectively, as dictated by electrical charges on either side of the cell membrane. This important difference from other cells is the basis of the so-called “chloride-shift” with the movement of chloride from the plasma into erythrocytes as blood moves from the arterial to the venous end of systemic capillaries. The Donnan ratio represents the behaviour of charged particles near a semi-permeable membrane with imbalanced distribution across the two sides of the membrane. Since most of the CO2 carried by the blood is in the form of HCO3, the chloride shift is important because it enhances the carrying capacity of the blood for HCO3. A major role of the chloride shift is therefore mitigation of the change in pH that occurs during gas transport. The chloride concentration is primarily regulated by the gastrointestinal tract and the kidneys. Chloride channels are expressed along the entire mammalian nephron. They participate in transepithelial chloride transport, cell volume regulation and acidification of intracellular vesicles. Abnormal chloride levels alone usually signify a more serious underlying metabolic disorder, such as metabolic acidosis or alkalosis. Abnormalities in chloride channel expression and function in many organs can cause a wide range of disorders. Chloride also is an irreplaceable component of diagnostic tests in many clinical situations.

Abstract:

For many years, resistance profiles for many of the Gram-negative pathogens were relatively stable. However, the past few decades have seen a significant global upsurge in antimicrobial resistance particularly among Enterobacteriaceae. Worldwide, the prevalence of extended-spectrum β-lactamase (ESBL)–producing Enterobacteriaceae is increasing, and these organisms are frequently resistant to many other key antibiotics such as fluoroquinolones and aminoglycosides. Carbapenem-producing Gram negative bacteria are an emerging threat, leaving few treatment options. UTIs are among the most common types of infections in urology practice, with approximately 150–250 million cases globally per year. Owing to their high prevalence, UTIs are a major contributor to global antibiotic use and resistance. Increasing antimicrobial resistance represents a challenge to urologic practice and without effective antibiotics active against common uropathogens, many urologic procedures would carry excessive risk. Although new antiobiotics with activity against Gram-negative bacteria, including activity against strains with highly resistant phenotypes, are now available and some more might be available in the near future, they are likely to be used as last resort, owing to their high cost. Furthermore, it is unlikely that any single agent would be effective against the great diversity of resistance we are currently facing. This presentation will summarise the mechanisms of resistance, the current European resistance trends of Gram-negative uropathogens, examine the effect of resistance on common urology procedures, and discuss key antibiotic options in the era of resistance.

Abstract:

Approximately 40% of world’s population lives in areas where malaria is endemic mainly in tropical and sub tropical regions. World Health Organization (WHO) estimated a staggering figure of 214 million new cases of malaria in 2015 with an estimated death of 438,000 worldwide, majority of which occurred in African countries. Acute kidney injury (AKI) is fairly common, and serious complications are seen in acute falciparum malaria in adults. Malaria associated kidney disease (MAKI) is defined as “An abrupt decline in renal function in a patient who is suffering from acute malaria within 48 hours of onset characterized by an elevation of serum creatinine >0.3 mg/dl or elevation of creatinine level by >50% and/or oliguria with urine output <0.5 ml/kg/hr in >6 hours.” Incidence of AKI varies from 0.4-60% and is due to the variation in age, immunity status and locality. Complications are caused by interaction of the parasite with the host resulting in mechanical, immunological and humoral responses. MAKI is a result of combinations of two processes - cytoadherance and cytokines. Parasite containing RBCs express a protein called ‘variant surface antigen’ (VSA) on their surface. These RBCs attach to vascular endothelium using VSA and sequestration of the same into glomerular and tubulo-interstitial capillaries may cause AKI. Cytokines cause an increase in nitric oxide in the vessels or facilitate mitochondrial shutdown thereby leading to generalized arterial vasodilatation, increased permeability, increased interstitial volume, renal vasoconstriction with retention of Na+ and H2O, tissue hypoxia and thereby leading to glomerular injury. The vulnerable groups of patient include the pregnant women, high parasitemia, jaundice, prolonged dehydration and those on NSAID therapy. Two subsets of population – AKI occurring as a component of multi organ dysfunction (MOD) or AKI as a sole complication of malaria appearing at a later stage when other components have subsided or treated or did not appear. The later bears a better prognosis. Urine output is usually <400 ml/day and may persist for 3-10 days. Cerebral malaria is associated with AKI in 30% of cases and worsens the prognosis. MAKI usually resolves in days to weeks, do not progress to chronic kidney disease (CKD) or acute tubular necrosis (ATN) and mortality ranges from 15 to 50%. Anti-malarials, fluid management, treatment and prevention of complications and dialysis are the mainstay of treatment. Early initiation of dialysis has proven mortality benefit.

Abstract:

Depression and mortality association is well recognized. However, studies regarding the link between depression and mortality among peritoneal dialysis (PD) are scarce. A prospective single cohort study was conducted, involving adults treated with PD within Kidney Center, General Hospital, Chiang Mai, Thailand between 15 May 2012 and 31 December 2014, and followed until 31 December 2016. Presence of depression was reported a Beck Depression Inventory (BDI) II score ≥ 14 at baseline. A sensitivity analysis was evaluated using a BDI-II threshold ≥ 20. Data on sociodemographics and risk factors for mortality were collected. Risk for all-cause mortality, CV mortality, and CV hospitalization were estimated using the multivariable Cox proportional hazards regression. 409 participants (mean age of 59.3±12.4 years, 56.0% men) were included. Of those, 117 (28.6%) reported BDI-II score ≥ 14. During the median follow-up period of 20.8 months (10,023 person-months), 139 died, of 50 were attributable to CV death. Depression were associated with all-cause mortality (adjusted hazard ratio, 2.54 [95% confidence interval, 1.87-3.64; P<0.001]), CV mortality (3.36 [1.43-7.87; P=0.005]), and CV hospitalization (2.96 [1.67-5.26; P<0.001]). For sensitivity analysis, a higher BDI-II score (≥20) were associated with all-cause mortality (3.28 [1.71-6.30; P<0.001]) and CV mortality (3.80 [1.98-7.29; P<0.001]), but not CV hospitalization (1.26 [0.48-3.30; P=0.630]). Depression is associated with a substantially increased risk of death and adverse CV outcomes in PD patients. Further studies are needed to determine whether the interventions to alleviate these symptoms would alter adverse clinical outcomes, including mortality.

Abstract:

Kidney transplantation is treatment of choice for advanced chronic kidney disease patients as it gives better quality and quantity of life as compared to dialysis. The morbidity and mortality secondary to infections after transplantation is determined by various factors which include age, pre-existing chronic diseases, living versus diseased graft, induction and degree of immunosuppression, nutritional and socio-economic status. Newer immunosuppressive drugs including induction agents have resulted in better graft and hence better patient survival. The main drawback however is the risk of infections. In India around 50% of the recipients have mortality secondary to infection. Urinary tract infection (UTI), tuberculosis, CMV, Hepatitis C and B were the most common infections encountered previously. With better immunization (Hepatitis B), prophylactic drugs (CMV) and treatment (Hepatitis C) their incidence have come down considerably. The spectrum has changed now to more of viral and fungal infections. BK virus, Herpes, EBV, parvo virus, nocardiosis, pneumocystis and fungal infections are being detected more frequently. It is essential for all physicians to be aware of this new trend and to be more suspicious of these infections in transplant recipients so that an early diagnosis and treatment can be initiated which translates into a better survival. There are very few studies about the infectious complications from India. Hence, we conducted this retrospective data analysis to dertermine the etiology of infections in single tertiary care center in India.

Abstract:

Introduction: Despite the significant progress achieved in the treatment and outcome of children with renal involvement due to systemic diseases (lupus, vasculitis), many questions remain in the early detection of cardiovascular complications, the leading cause of death in these patients in adulthood.

Aim: This study is contributed to find out the risk of developing cardiovascular disease (CVD) in patients with lupus nephritis (LN), IgA Henoch-Schonlein purpura nephritis (HSPN) and ANCA-associated nephritis.

Materials: 49 children were enrolled in the study: 24 with lupus (2 boys, 7-17 years, median age 13.8), 21 with HSPN (10 boys, 3-17 yrs, median 10.5) and 4 with ANCA nephritis (2 boys, 7-17 yrs, median 11.8). All patients had morphological verification of the disease. As a control group 37 healthy children were examined. 24 hours monitoring of blood pressure (BP), ECHO-CG, carotid intima media thickness (cIMT), left ventricles mass index (LVMI), relative thickness of left ventricles wall (RTLV), body mass index (BMI), serum lipids levels, serum glucose, serum uric acid, eGFR and markers of vascular endothelial dysfunction VEGF and TGF1β were measured.

Results: Arterial hypertension was observed in 35/49 (72%) of children with glomerular diseases. In 21/24 of patients with LN (88%), in 100% of ANCA nephritis and 10/21 HSPN (48%), required of an average 3 hypotensive drugs. Dilatations of the LV in 24%, reduced ejection fraction in 2.1% of all patients were seen. LVMI, RTLV, BMI and cIMT were higher compared with healthy (p<0.05). In patients with nephritis concentration of serum VEGF and TGF1β correlated with AG. The mean serum cholesterol level was 5.8 mmol/l in LN, 6.94 in ANCA nephritis and 5.16 in patients with HSPN (p<0.05), lipoproteins of low and very low density prevailed. The mean serum glucose level was not significantly higher than in healthy, in contrast to the level of uric acid (p<0.05), especially in patients with ANCA nephritis (p<0.01).

Conclusions: In patients with LN, HSPN and ANCA-associated nephritis abnormalities in serum lipids level were correlated with disease activity and duration, younger age of diagnosis, mean cIMT, eGFR, increased systolic and diastolic BP, BMI, LVMI, RTLV, concentration of VEGF and TGF1β. Such patients are at high risk of early development of cardiovascular complications requiring early correction.

Abstract:

Nocturnal enuresis is a common disorder that affects the social life and mental health of a child. The objective of this study was to understand the remission rates, shifts in treatment methods used by parents and parents’ attitudes towards their children with primary nocturnal enuresis. A total of 408 children aged 6-12 years, diagnosed with primary nocturnal enuresis from a 2004 epidemiological study in Taiwan, were enrolled in this follow-up study. After a 5.5 year follow-up period, the remission rates of the children of each age group were evaluated, and the corresponding treatment methods were employed daily. Furthermore, the major risk factors that influenced the remission rates in these children were investigated. The overall remission rate was 93.1% among all age groups and the median age of remission was 9.9 years (95% C.I. = 9.5-10.2 years). The most common coping strategy was limiting water intake before sleep (42.3%). However, if enuresis continued to worsen as their children mature, parents will consider medical intervention. A Cox proportional hazards regression model revealed that girls, young children, those with fewer instances of bed-wetting, and light sleepers had higher remission rates than those of their counterparts. Children who were deep sleepers or affected by severe enuresis had a low probability of achieving dryness. However, girls and young children had a higher probability of achieving remission than their counterparts.
