Light chain nephropathy |
p. 437 |
Sihem Darouich, Ilhem Bettaieb, Raja Aouadia, Hafedh Hedri, Ezzeddine Abderrahim, Rym Goucha, Adel Khedher DOI:10.4103/1319-2442.157296 PMID:26022011Light chain deposition disease (LCDD) is characterized by the tissue deposition of monotypic immunoglobulin light chains of either kappa or lambda isotype. It is the archetypal systemic disease that is most frequently diagnosed on a kidney biopsy, although the deposits may involve several other organs. This brief review focuses on the clinicopathological features of LCDD-associated nephropathy with an emphasis on the diagnostic and therapeutic difficulties related to this elusive condition. |

Frequency of occurrence of urinary tract infection in double j stented versus non-stented renal transplant recipients |
p. 443 |
Durre Shohab, Athar Khawaja, Emad Atif, Imran Jamil, Iftikhar Ali, Saeed Akhter DOI:10.4103/1319-2442.157298 PMID:26022012Prophylactic ureteric stenting in renal transplant recipients prevents major surgical complications such as ureteric leak and obstruction on the one hand while, on the other hand, it is associated with complications like urinary tract infections (UTI), hematuria, stent migration, stent encrustation and forgotten stents. UTI is documented to be most common complication associated with double J (DJ) stent. In this retrospective observational study involving 157 patients, we compared the frequency of occurrence of UTI in DJ-stented versus non-stented renal transplant recipients. The study patients had undergone renal transplantation, with or without DJ-stenting, between January 2007 and June 2012. The mean age of the study subjects was 34.01 ± 14.63 years. The patients were followed-up for one year post-transplantation with regular evaluation, including detailed assessment, complete blood picture, renal function tests, routine urine examination and cultures. Data were collected through chart and electronic record review. Of a total of 157 patients, 61 (38.85%) developed UTI, including 30 of 74 stented patients (40.54%) and 31 of 83 non-stented renal transplant recipients (37.34%). Relative risk was calculated to be 1.08. The mean serum creatinine at the end of one year was 1.47 mg/dL in DJ-stented patients and 1.36 mg/dL in nonstented patients. Our study suggests that there is no significant difference in the frequency of UTI between DJ-stented and non-stented renal transplant recipients. |

Comparison of safety and efficacy of general and spinal anesthesia in kidney transplantation: Evaluation of the peri-operative outcome |
p. 447 |
Mohammad Ali Amir-Zargar, Mahmoud Gholyaf, Abdolmajid Iloon Kashkouli, Ahmad Moradi, Saadat Torabian DOI:10.4103/1319-2442.157300 PMID:26022013General anesthesia is a routine anesthetic technique for kidney transplantation. This study evaluated and compared the peri-operative hemodynamic, cardiopulmonary and general condition status in patients in whom spinal anesthesia (SA) or general anesthesia (GA) was used for kidney transplantation. A prospective study was carried out on 49 consecutive patients who underwent kidney transplantation with either GA (19 patients, mean age 37.53 ± 11.78 years) or SA (30 patients, mean age 42.17 ± 14.89 years), without any selection bias. One obese patient with a body mass index of 32.52 kg/m 2 died 22 days after transplantation in the GA group. One other patient, who developed severe nausea and vomiting, was changed from SA to GA. There were no statistical differences in gender, mean age, body mass index and hemodynamic and cardiopulmonary status between the two groups. Time to post-operative diet tolerance, defecation, ambulation and adequate urination were significantly better in the SA group. The mean operation time was 264.32 ± 18.91 and 233 ± 15.12 min in the GA and SA groups, respectively. Brisk diuresis was seen in all patients except one in the SA group. Our study suggests that kidney transplantation under SA is feasible and safe, particularly for patients who cannot receive GA. |

Comparison between valganciclovir and aciclovir/valaciclovir for CMV prophylaxis in pediatric renal transplantation |
p. 453 |
M Fila, A Dechartes, A Maisin, C Dossier, W Zhao, G Deschênes, V Baudouin DOI:10.4103/1319-2442.157306 PMID:26022014Prophylaxis has dramatically decreased the occurrence of cytomegalovirus (CMV) infection after renal transplantation. Optimal regimens of treatment remain controversial, especially in pediatric recipients. The aim of this study was to evaluate the effectiveness of valganciclovir (VGC) versus aciclovir/valaciclovir (ACV) in a pediatric renal transplant population. Data from 101 renal transplantations were retrospectively analyzed. Except those with R-/Dstatus, all patients received prophylaxis either with ACV, n = 39 or VGC, n = 38. Incidences of positive CMV antigenemia and disease, as well as the delay in relation to the prophylaxis, were collected during at least 12 months after the end of treatment. Positive CMV antigenemia was reported in 34 patients (ACV: 16, VGC: 16, no prophylaxis: 2). CMV disease occurred in 15 patients (ACV: 5; VGC: 8) (ns). For the majority of patients under VGC, positive CMV antigenemia occurred within the year following the withdrawal of prophylaxis (VGC: 14; ACV: 5, P <0.05), whereas it occurred during prophylaxis in 11 patients under ACV versus two under VGC (P <0.05). The over-all incidence of positive CMV antigenemia was similar between ACV and VGC prophylaxis. However, VGC was more efficient to prevent early CMV infection while patients treated with ACV had less CMV infection or disease after the end of the prophylaxis. |

Tumor necrosis factor gene expression in regular hemodialysis patients |
p. 460 |
Hemmat E El Haddad, Mohamed A Marie, Tarek M Samy, Reem Jan Farid, Mai Sherif, Usama A Sharaf El Din DOI:10.4103/1319-2442.157309 PMID:26022015This study evaluates tumor necrosis factor (TNF)-alfa gene expression in patients with end-stage renal disease (ESRD) on regular hemodialysis as an expression of cardiovascular disease (CVD) risk even on a sub-clinical level and its relation to some of the parameters incriminated in the pathogenesis and the establishment of uremic arteriopathy. A total of 51 patients with ESRD on regular hemodialysis and 20 healthy subjects matching in age and gender as a control group were recruited. All selected cases were subjected to serum lipid profile, Creactive protein (CRP), TNF-alfa gene expression and Doppler study of carotid arteries to estimate carotid intimal media thickness (cIMT). Serum triglycerides (TGS) level (P <0.001), CRP positivity (P = 0.002), relative quantification (RQ) of TNF-alfa gene expression (P = 0.007) and cIMT (P = 0.02) were significantly higher while high-density lipoprotein (HDL) level (P <0.001) was significantly lower among cases compared with controls. RQ showed a significant positive correlation with CRP titer (rho = 0.583, P = 0.011). Results also showed a significant strong negative correlation between with CRP titer and cIMT (rho = -0.590, P = 0.010). CRP titer showed only a significant strong negative correlation with age (rho = -0.589, P = 0.01) and positive correlation with HDL (rho = 0.51, P = 0.031). Patients with ESRD have increased gene expression of TNF-alfa and CRP titer together with increased atherosclerosis as expressed by increased cIMT. |

Effect of vitamin C supplementation on marital satisfaction in patients undergoing hemodialysis: A randomized, double-blind and placebo-controlled trial |
p. 468 |
Vajihe Biniaz, Ali Tayebi, Abbas Ebadi, Shermeh Sadeghi, Behzad Einollahi DOI:10.4103/1319-2442.157312 PMID:26022016One of the common problems in patients on hemodialysis (HD) is marital dissatisfaction. Because anemia and fatigue are two important factors for marital dissatisfaction, and vitamin C can ameliorate both of them, we carried out this study to evaluate the effect of vitamin C on marital satisfaction among HD patients. This randomized, placebo-controlled, double-blind and parallel-group trial was conducted on 62 HD patients. The MFI-20 and ENRICH questionnaires were completed at the start and end of study. Required laboratory parameters including serum levels of hemoglobin (Hb), hematocrit (Hct) and ferritin were also measured at the start and at the end of the study. In the intervention group, 250 mg of vitamin C was injected intravenously immediately at the end of each HD session three times a week for eight consequent weeks. In the control group, placebo saline was injected. There was a significant change in the level of fatigue (P = 0.01) and the serum levels of Hb (P = 0.006) and Hct (P = 0.02). The mean of the marital satisfaction score increased significantly in the intervention group (P = 0.001): Baseline score of 35.7 ± 5.10 versus a final score of 38.0 ± 5.30. However, the mean of marital satisfaction score decreased in the control group: Baseline 37.1 ± 7.10 versus a final score of 34.7 ± 7.40. Our findings suggest that vitamin C supplementation can modify the marital satisfaction. Further studies are recommended. |

The effectiveness of systemic antibiotic therapy with and without ethanol-locked solution in the treatment of hemodialysis-related catheter infection |
p. 477 |
Hamid Tayebi Khosroshahi, Hosein Mahdipur, Sahar Parkhideh, Saiid Basmenji, Mohammadreza Khalilzadeh, Majid Tozihi DOI:10.4103/1319-2442.157315 PMID:26022017Bacterial overgrowth in the inner layer of the catheter as a biofilm is highly encountered in routine medical care, and it may occur in a few days after inserting a catheter as an access in hemodialysis (HD) patients. Catheter-induced bacteremia is often due to the development of biofilms. Locking catheters with antimicrobial agents is an effective way of reducing the risk of catheter-related infection. In a controlled, randomized clinical trial, 64 chronic HD patients (32 men and 32 women with a mean age of 57.5 ± 15.6 years) were divided into case and control groups, with 32 patients in each group. The case group received systemic antibiotic and a lock of catheters with 60% ethanol and the control group received only systemic antibiotic. The results were evaluated after three weeks of treatment. The success rate of clearing infection in group A (29 patients) and group B (18 patients) was 90.6% and 56.2%, respectively (P = 0.002). We conclude that the significant difference in the success rate of clearing catheter infection in HD patients is due to the use of 60% ethanol-lock along with antibiotic therapy, and suggest this for routine use. |

Renal failure in patients with multiple myeloma |
p. 482 |
Samir H Almueilo DOI:10.4103/1319-2442.157327 PMID:26022018Renal dysfunction is encountered in 20-25% of patients with multiple myeloma (MM) at the time of diagnosis. There is often a precipitating event. Several biochemical and clinical correlations with renal failure in MM have been reported. Renal failure in MM is associated with worse outcome of the disease. We retrospectively analyzed the medical records of 64 patients with MM admitted to our institution during the period January 1992 to December 2012. Abnormal renal function was observed in 24 (37.5%) patients and 17 (26.6%) of them had renal failure; 14 of the 17 (82.4%) of patients with renal failure had Stage III MM. Urine Bence- Jones protein was positive in ten (58.8%) patients with renal failure versus ten (21.3%) patients without renal failure (P = 0.004). Potential precipitating factors of renal failure were determined in nine patients. Renal function normalized in 11 patients with simple measures, while six patients required hemodialysis; one remained dialysis dependent till time of death. Early mortality occurred in five (29.4%) patients with renal failure as compared with two (4.3%) patients in the group without renal failure (P = 0.005). In conclusion, renal failure is associated with a higher tumor burden and Bence-Jones proteinuria in patients with MM. It is reversible in the majority of patients; however, early mortality tends to be higher in patients with persistent renal failure. |

Cardiac surgery-associated acute kidney injury in a developing country: Prevalence, risk factors and outcome |
p. 489 |
Ekanem Nsikak Ekure, Christopher Imokhuede Esezobor, Anuradha Sridhar, Jyothi Vasudevan, Rajhavan Subramanyan, Kotturathu Mammen Cherian DOI:10.4103/1319-2442.157328 PMID:26022019Little is known about cardiac surgery-associated acute kidney injury (CS-AKI) in children in developing regions of the world. The study aimed to determine the prevalence of CSAKI, associated factors and its impact on mortality and utilization of hospital services. The hospital records of children aged 0-17 years who underwent CS at an Indian hospital were reviewed. CS-AKI was defined as a rise in serum creatinine of ≥0.3 mg/dL in any 48 h and or by urine output <0.5 mL/kg/h for an 8-h period in the first five days after CS. The study included 323 children with a median age of one year (0.04-17), of whom 22 (6.8%) were neonates and 18.3% had a single ventricle. About 60% of the children had Risk Adjusted Congenital Heart Surgery-I category 1 or 2 interventions. CS-AKI occurred in 39 children (12.1%). Factors associated with CS-AKI were sepsis and intraand post-operative hypotension. In-hospital mortality was six-fold higher in children who developed CS-AKI. CS-AKI was associated with two to three days more of mechanical ventilation and Intensive care unit stay. CS-AKI occurs in children in developing countries, but at a lower frequency mainly due to the predominance of post-neonatal children undergoing less-complex CSs. CS-AKI was associated with higher in-hospital mortality and increased utilization of hospital services. Factors associated with CS-AKI included intraand post-operative hypotension and sepsis. |

Serum cystatin C, urinary neutrophil gelatinase-associated lipocalin and N-acetyl-beta-D-glucosaminidase in juvenile and adult patients with systemic lupus erythematosus: Correlation with clinical manifestations, disease activity and damage |
p. 497 |
Tamer A Gheita, Abeer M. Nour El Din Abd El Baky, Heba S Assal, Tarek M Farid, Inas A Rasheed, Eman H Thabet DOI:10.4103/1319-2442.157336 PMID:26022020Lupus nephritis (LN) is a potentially devastating outcome of systemic lupus erythematosus (SLE). It is important to identify reliable, non-invasive methods to assess the kidneys in patients with SLE. The aim of the study was to measure the level of novel markers of renal involvement in these patients and assess their correlation with disease activity and damage. Sixtyone patients with SLE (33 adults and 28 juvenile) were included in the study. Fifty-two ageand sex-matched healthy individuals served as controls. Full history taking, thorough clinical examination and laboratory investigations were performed and disease activity and damage were assessed for all patients. Renal bio-markers including serum cystatin C, urinary neutrophil gelatinase-associated lipocalin (UNGAL) and N-acetyl-beta-D-glucosaminidase (UNAG) were assessed in patients and controls. There was a significant increase in serum cystatin C, UNGAL and UNAG levels in the adult SLE patients compared with controls (P = 0.000, P = 0.013 and P = 0.018, respectively); serum cystatin C and UNGAL levels were higher in the juvenile patients compared with controls (P = 0.038 and P = 0.000, respectively). Serum cystatin C significantly correlated with the damage index, renal biopsy class and negatively with the serum albumin; UNGAL correlated with albuminuria and the level of nephritis and UNAG negatively correlated with serum albumin level. Our study suggests that serum cystatin C, UNGAL and UNAG are important markers of LN and both cystatin C and UNAG would help in predicting the renal biopsy class. |

Urinary monocyte chemoattractant protein-1 as a biomarker of lupus nephritis activity in children |
p. 507 |
Emad E Ghobrial, Azza A El Hamshary, Ashraf G Mohamed, Yomna A Abd El Raheim, Ahmed A Talaat DOI:10.4103/1319-2442.157350 PMID:26022021Systemic lupus erythematosus (SLE) is a life-long, life-limiting and multi-systemic autoimmune disease. Glomerulonephritis is one of the most serious manifestations of SLE. Younger children have an increased incidence, severity and morbidity of lupus nephritis (LN) compared with adult-onset disease. Monocyte chemoattractant protein-1 (MCP-1) enhances leukocyte adhesiveness and endothelial permeability in the kidneys of murine and human LN models. Our study aimed to assess the role of urinary MCP-1 in the early diagnosis of LN activity. Sixty children, of whom 45 children aged from six to 12 years old and of both sexes (15 SLE patients without nephritis, 15 active LN and 15 inactive LN) fulfilling the American College of Rheumatology Classification Criteria for SLE were studied in comparison with 15 healthy subjects. We investigated the serum and urinary MCP-1 in all groups using the enzyme-linked immunosorbent assay test. Urinary MCP-1 was significantly higher in active LN in comparison with inactive LN and controls, and also significantly higher in inactive LN in comparison with SLE without nephritis and controls. There was also a significant difference between SLE without nephritis and controls. Serum MCP-1 was significantly higher in the group with active LN in comparison with the inactive group and SLE without nephritis and controls, but there was no significant difference between SLE and controls. The urinary MCP-1 level correlated well with SLE disease activity as measured by the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI). Urinary MCP-1 correlates positively with proteinuria, blood urea nitrogen level and creatinine and negatively with hemoglobin and creatinine clearance. We concluded that measurement of MCP-1 in urine may be useful for monitoring the severity of renal involvement in SLE. We recommend measuring urinary MCP-1 in pediatric SLE for the early diagnosis of LN and for the evaluation of the severity of renal involvement. |

Treatment of IgA nephropathy based on the severity of clinical and histological features |
p. 516 |
Pantelitsa Kalliakmani, Dimitrios Komninakis, Miltiadis Gerolymos, Marios Papasotiriou, Eirini Savvidaki, Dimitrios S Goumenos DOI:10.4103/1319-2442.157356 PMID:26022022Immunoglobulin A (IgA) nephropathy (IgAN) represents a common glomerular disease treated by various therapeutic regimens. We studied 50 IgAN patients to determine the effect of different regimens selected according to severity of the disease on the clinical outcome of patients over a follow-up period of five years. Patients with normal renal function and proteinuria <1 g/24-h received no treatment (Group A, n = 6). Thοse with normal renal function, proteinuria >1 g/24-h and mild to moderate histological lesions received angiotensin-converting enzyme inhibitors (ACEi) and corticosteroids (Group B, n = 23). Patients with baseline serum creatinine (Scr) <2.5 mg/dL, proteinuria >3.5 g/24-h and severe histological lesions received ACEi, corticosteroids and other immunosuppressive drugs (Group C, n = 18). Finally, patients with Scr >2.5 mg/dL, glomerulosclerosis and tubulointerstitial fibrosis received ACEi and fish oil (Group D, n = 3). Doubling of baseline Scr was observed in nine (18%) patients; two (8.7%) patients from Group B, five (27.7%) patients from Group C and two (66.7%) patients from Group D. Of the seven (14%) patients who reached end-stage renal disease, one (4.3%) patient was from Group B, four (21.0%) patients were from Group C and two (66.7%) patients were from Group D. Reduction of proteinuria was observed in all (100%) patients from Group B and in 15 (83.3%) patients from Group C. Adverse reactions occurred in three of 18 (16%) patients treated with immunosuppressive drugs. The choice of therapeutic regimen used in the treatment of patients with IgAN could be based on the severity of clinical and histological involvement in order to achieve the maximum effect with the least of adverse reactions. |

Cardiovascular risk in lupus nephritis: Do renal disease-related and other traditional risk factors play a role? |
p. 526 |
Inoshi Atukorala, Praveen Weeratunga, Janaka Kalubowila, Hasanthika Ranasinghe, Nalika Gunawardena, Rushika Lanerolle, Nadeeka Rathnamalala DOI:10.4103/1319-2442.157357 PMID:26022023This study was performed to evaluate the prevalence of thickened carotid intima media thickness (CIMT) in a Sri Lankan cohort of lupus nephritis (LN) patients and to identify associations between traditional cardiovascular disease (CVD) and LN-related risk factors with increased CIMT. Consecutive patients with biopsy-proven LN were evaluated for conventional CVD risk factors, renal parameters and extent of organ involvement in this cross-sectional study. Current disease activity and damage were assessed by the British Isles Lupus Activity Group (BILAG) score and the Systemic Lupus International Collaborative Clinics/American College of Rheumatology (SLICC/ACR) damage index, respectively. CIMT was assessed by B Mode grey scale ultrasonography. Increased CIMT was defined as CIMT more than the 75th percentile based on cutoffs from the "Carotid Atherosclerosis Progression Study." Forty patients (98% female), with a mean age of 38 years (age range of 20-50) and of South Asian descent, were evaluated. The mean duration of disease of 6.15 years (SD = 4.66). The overall prevalence of cardiovascular events was low and included previous acute coronary syndromes in 7.5%, stable angina in 5%, cerebrovascular accidents in 7.5% and transient ischemic attacks in 2.5% of the patients; 72.5% had hypertension (HTN) [mean blood pressure (BP) 140/80 mm Hg]; 32.5% had dyslipidemias (mean serum cholesterol 5.9; SD = 5.6) and 25% had diabetes (mean blood sugar 103.7; SD = 15.6). Forty percent were obese and 20% were overweight (Asian cutoffs). Increased CIMT (57.5%) and atherosclerotic plaques (15.36%) indicated a high CVD risk in this cohort. Diabetes (P = 0.016), HTN (P = 0.002), dyslipidemia (P = 0.002) and obesity (P = 0.048) were associated with thickened CIMT. The only LN-related risk factor associated with thickened CIMT (P <0.05) was the SLICC/ACR damage index. The independent predictors of thickened CIMT determined by logistic regression analysis were HTN and dyslipidemia. |

Short-term effects of renal transplantation on coronary artery calcification: A prospective study |
p. 536 |
Pratyusha Priyadarshini, Sandeep Aggarwal, Sandeep Guleria, Sanjiv Sharma, Gurpreet Singh Gulati DOI:10.4103/1319-2442.157359 PMID:26022024Cardiovascular disease is a leading cause of mortality in renal transplant recipients. Coronary artery calcification (CAC) has been found to have good correlation with atherosclerosis and cardiovascular morbidity. The objective of our study was to assess the prevalence of CAC and the long-term effects of renal transplantation on CAC and carotid intima-medial thickness (CIMT) in Indian renal transplant recipients. Twenty-eight renal transplant recipients were included in this prospective study. Dual-source computed tomography and calcium scoring using Agatston's method and CIMT measurement were performed at the time of transplant and then repeated at six and 12 months after transplantation. The prevalence of CAC in our study patients was low (32%), probably because they were young, had been on dialysis for a short duration and had undergone live-related renal transplant. An overall improvement in biochemical parameters was observed after transplantation. Patients with zero baseline calcium score did not show progression. Patients with baseline calcium score more than zero showed initial progression at 6 months and no further progression afterwards. There was good correlation between CIMT and CAC score. Our study suggests that renal transplantation does not reverse the calcification but appears to decrease the rate of progression in the long term. |

Level of dietary awareness among Saudi dialysis patients and the influence of various factors |
p. 544 |
Abdulmajeed A AlSadhan, Fayez Hejaili, Salih Bin Salih DOI:10.4103/1319-2442.157360 PMID:26022025Our objective was to investigate the degree of dietary awareness of Saudi patients on chronic hemodialysis and influencing factors on this awareness. This is an interviewadministered survey-based cross-sectional study carried out on adult dialysis patients at the King Abdulaziz Medical City, Riyadh. The first part of the survey consisted of the collection of demographic data and the second part consisted of questions in the areas of awareness on the dietary influence of sodium, potassium, fluid intake and calcium/phosphorous and lipids. The questions are simply answered as "yes" or "no." The overall awareness score was 79%. The awareness scores were highest in the area of lipids (86.5%) and lowest in the fluid intake area (71.3%). The scores for sodium, phosphorous/calcium and potassium were 80%, 79.6% and 73%, respectively. The degree of awareness was influenced by the number of visits by the dietitian (P = 0.008) and the educational level of the patients (P = 0.02), but not by age, duration on dialysis or gender. In conclusion, our findings suggest that there is a need for better of awareness among our dialysis patients. The highest score for awareness was seen in the cholesterol-related questions and the lowest score was seen in the fluid intake questions area. This is influenced by the number of visits by the dietitian and the educational level of the patients, but not by age, duration on dialysis or gender. |

Incidence and risk factors of acute kidney injury among the critically ill neonates |
p. 549 |
Ayman A El-Badawy, Samuel Makar, Abdel-Rahman A Abdel-Razek, Dalia Abd Elaziz DOI:10.4103/1319-2442.157362 PMID:26022026Acute kidney injury (AKI) is a complex disorder with clinical manifestations ranging from mild dysfunction to complete kidney failure. The published literature on the incidence and outcome of AKI in the critically ill neonatal population is scarce. The aim of this study was to evaluate the types, the associated risk factors and short-term outcome of AKI in the critically ill neonates. A cohort study was conducted including 100 critically ill neonates successively admitted to the Neonatal Intensive Care Unit. The inclusion criteria were a gestational age ≥28 weeks and body weight ≥1 kg. Exclusion criteria included those with multiple congenital anomalies or on drugs altering glomerular filtration rate or AKI developing postoperatively. Neonates were evaluated for the development of AKI [creatinine >1.5 mg/dL and/or blood urea nitrogen (BUN) >20 mg/dL] and were assigned as group A (who developed AKI) and group B (who did not develop AKI). Forty-one patients developed AKI (group A) among whom nine (22%) showed oliguric AKI. The most common risk factors among group A patients were sepsis (75.6%) and nephrotoxic drug administration (75.6%), followed by shock (39%). There were no statistically significant differences between both groups except for male sex predominance and necrotizing enterocolitis (NEC), which were significantly higher among group A (P <0.05). Use of continuous positive airway pressure (CPAP) ventilation was significantly higher in neonates without AKI (13.6% vs 0.0%, P = 0.02). The mortality rate among group A reached 51.2%. Various risk factors including gender, gestational age, birth weight, shock, NEC, sepsis, nephrotoxic drugs, oliguria and mechanical ventilation were studied as regards outcome of group A, and all factors except gender and oliguria proved to be significantly higher in deceased neonates. Male sex and NEC were important risk factors for developing AKI that was predominantly non-oliguric. CPAP ventilation may have a protective effect against AKI. The mortality rate was more than three times higher in the AKI group. |

Orthotropic liver transplantation for intractable neurological manifestations of Wilson's disease |
p. 556 |
Vaibhav K Sutariya, Anad H Tank, Pranjal R Modi DOI:10.4103/1319-2442.157365 PMID:26022027Wilson's disease (WD) is an inherited autosomal recessive disorder characterized by copper accumulation and toxicity, affecting mainly the liver and brain. Orthotopic liver transplantation (OLT) is the definitive therapy for patients with WD. Acute fulminant hepatic failure and decompensated cirrhosis are well-established indications for OLT. Patients with severe neurologic impairment can also be benefited by OLT. Here, we present a patient who underwent OLT for isolated neurological WD. |

The stuck dialysis catheter: A nasty astonishment |
p. 560 |
Georgios Galanopoulos, Constantinos Lambidis DOI:10.4103/1319-2442.157366 PMID:26022028Removal of a tunneled cuffed central venous catheter can be challenging and risky. In some cases, the catheter firmly adheres to the surrounding tissues, becoming an integrated part of the vessel wall. We present the case of an adult female hemodialysis (HD) patient with a dysfunctioning HD tunneled cuffed catheter. The catheter removal procedure proved mazy. After several attempts, the catheter was removed together with the peri-catheter fibrin sheath. However, the post-procedure period was uneventful. |

Sphingomonas paucimobilis peritonitis: A case report and review of the literature |
p. 567 |
Dhanya Mohan, Mohammed Railey DOI:10.4103/1319-2442.157371 PMID:26022030Sphingomonas paucimobilis, a yellow-pigmented, aerobic, glucose non-fermenting, Gram-negative bacillus, is a rare cause of human infection normally associated with immunocompromised hosts. It has been associated with a few cases of continuous ambulatory peritoneal dialysis (PD) and is notorious for its resistance to the commonly used antibiotics. In half of the cases reported so far, the peritonitis was refractory to treatment, necessitating PD catheter removal. We report a case of Sphingomonas paucimobilis peritonitis in a 50-year-old patient who had been on PD for two years. The patient was successfully treated with intraperitoneal and intravenous antibiotics and the PD catheter was salvaged. |

Herb-induced acute bone marrow intoxication and interstitial nephritis superimposing glomerular C1q deposition in a patient with paroxysmal nocturnal hemoglobinuria |
p. 572 |
Deena T Boqari, Shatha Al Faraj, Maria Arafah, Nourah Aloudah, Khalid S Alkhairy, Ahmed Alsuhaibani, Khaled O Alsaad DOI:10.4103/1319-2442.157384 PMID:26022031Paroxysmal nocturnal hemoglobinuria is a rare disease of the red blood cell membrane that renders it lyzable by the complement system, leading to chronic intravascular hemolysis. Renal hemosiderosis is a well-known complication of intravascular hemolytic anemia and can lead to acute kidney injury and renal failure. The use of herbal medicine is common worldwide. The nephrotoxicity of herbal remedies can take several forms, which include acute kidney injury and acute and chronic interstitial nephritis. In addition, the use of herbal remedies can result in bone marrow toxicity and suppression. C1q nephropathy is an uncommon form of glomerular disease characterized by dominant or co-dominant glomerular immunofluorescence positivity for C1q in the absence of clinical and serological evidence of systemic lupus erythematosus, and has various clinical presentations and outcome. Here, we report a patient of undiagnosed paroxysmal nocturnal hemoglobinuria who consumed herbal medicine of unknown constituents and clinically presented with anemia and acute kidney injury. The pathological findings of bone marrow and renal biopsies that include bone marrow intoxication, severe renal hemosiderosis and acute interstitial nephritis and kidney injury, as well as co-dominant glomerular deposition of C1q, are discussed. In addition, we discuss and hypothesize the possible pathogenesis of glomerular C1q deposition in the setting of paroxysmal nocturnal hemoglobulinuria. |

Hypothermia and hypokalemia in a patient with diabetic ketoacidosis  |
p. 580 |
Osamu Saito, Takako Saito, Taro Sugase, Eiji Kusano, Daisuke Nagata DOI:10.4103/1319-2442.157387 PMID:26022032We present the case of a 36-year-old man with type-1 diabetes who was hospitalized with diabetic ketoacidosis (DKA). On admission, he had hypothermia, hypokalemia and combined metabolic and respiratory alkalosis, in addition to hyperglycemia. Hypothermia, hypokalemia and metabolic alkalosis, with a concurrent respiratory alkalosis, are not commonly seen in DKA. After admission, intravenous infusion of 0.45% saline was administered, which resulted in the development of pure metabolic acidosis. After starting insulin infusion, hypokalemia and hypophosphatemia became evident and finally resulted in massive rhabdomyolysis. Hyperkalemia accompanying oliguric acute kidney injury (AKI) warranted initiation of hemodialysis (HD) on Day-five. On the 45th hospital day, his urine output started to increase and a total of 22 HD sessions were required. We believe that in this case severe dehydration, hypothermia and hypokalemia might have contributed to the initial symptoms of DKA as well as the prolongation of AKI. |

Coexistence of sickle cell nephropathy and lupus nephritis in a Sudanese child |
p. 584 |
Ahmed B Idris, Ala Abdulgayoom, Eman Mudawi, AM El Hassan, Elwaleed Mohamed Elamin, Lamyaa Ahmed Mohamed El Hassan DOI:10.4103/1319-2442.157397 PMID:26022033In spite of the wide distribution of sickle cell disease (SCD) in Africa, an association with systemic lupus erythromatosis (SLE) is seldom reported. This may be due to the poor association between the two diseases or the high prevalence of missed cases. Progressive renal injury is prominent in both SCD and SLE. In this communication, we are presenting a case of an 11-year-old male who presented with sickle cell nephropathy that manifested as nephrotic syndrome with no response to conservative therapy, alongside unexplained massive hemolysis. His renal biopsy proved SLE superimposed on sickle cell nephropathy. We are stressing the importance of considering alternate disease processes in patients with SCD when symptoms change or when there is an atypical clinical course. |

Profile of renal diseases in Iraqi children: A single-center report |
p. 613 |
Shatha Hussain Ali, Fadhil Shanan Hussien, Haider Abd Al-Amer DOI:10.4103/1319-2442.157422 PMID:26022043Renal disease in hospitalized children can be difficult to diagnose early as it may exhibit few symptoms, unlike in adults. This study reports the epidemiological data, percentages and types of renal disorders in children seen at the pediatric nephrology center of the AlKadhymia Teaching Hospital, Baghdad, Iraq. A retrospective review of the charts of all patients, aged between one month and 14 years, who were admitted and followed-up for a period of three years from January 2009 till January 2012 were studied. The presence of renal disease based on their clinical records, laboratory tests and final diagnosis were noted. A total of 4785 children were admitted during the study period, of whom 326 renal disorders were observed in 281 children (5.8%). The affected children included 158 males (56.2%) and 123 females (43.7%). Majority of the cases were above two years of age (n = 181; 64.4%). Among them, urinary tract infection, seen in 60 patients (18.4%), was the most common renal disease, followed by nephrotic syndrome (n = 52; 15.9%), renal stone disease (n = 49; 15%), congenital malformations (n = 46; 14.1%), acute renal failure (n = 37; 11.3%), chronic renal failure (n = 22; 6.7%), glomerulonephritis (n = 16; 4.9%), isolated hematuria (n = 14; 4.2%), hypertension (n = 8; 2.4%), tubular disorders [renal tubular acidosis (n = 8; 2.4%), isolated hypercalciuria (n = 7; 2.1%), Bartter syndrome (n = 1; 0.3%)] and Wilm's tumor in six (1.8%) patients. The spectrum of renal disorders in Iraq is wide, and is similar to those reported from other developing countries with a predominance of infectious diseases. |

Outcome assessment of pregnancy-related acute kidney injury in Morocco: A national prospective study |
p. 619 |
Nadia Kabbali, Nabil Tachfouti, Mohammed Arrayhani, Mustapha Harandou, Mounia Tagnaouti, Yassamine Bentata, Inass Laouad, Benyounes Ramdani, Rabia Bayahia, Zouhair Oualim, Tarik Sqalli Houssaini DOI:10.4103/1319-2442.157426 PMID:26022044Acute kidney injury (AKI) is a rare but life-threatening complication of pregnancy. The aim of this paper is to study the characteristics of acute AKI in pregnancy and to emphasize on its management modalities in Moroccan hospitals. This is a national prospective study performed over six months from July 1 to December 31 2010 on AKI developing in pregnant patients, both preand post-partum period. Patients with pre-existing kidney disease were excluded from the study. Outcome was considered unfavorable when complete recovery of renal function was not achieved and/or maternal death occurred. Forty-four patients were included in this study. They were 29.6 ± 6 years old and mostly illiterate (70.6%). Most AKI occurred in the post-partum period, with 66% of the cases occurring in those who did not receive antenatal care. The main etiologies were pre-eclampsia (28 cases), hemorrhagic shock (six cases) and septic events (five cases). We noted three cases of acute fatty liver, one case of obstructive kidney injury and one case of lupus nephritis. Hemodialysis was necessary in 17 (38.6%) cases. The outcome was favorable in 29 patients. The maternal mortality rate was 11.4%. Two poor prognostic factors were identified: Age over 38 years and sepsis. AKI is a severe complication of pregnancy in developing countries. Its prevention necessitates the improvement of the sanitary infrastructure and the establishment of the obligatory antenatal care. |

Restless leg syndrome in hemodialysis patients: A disorder that should be noticed |
p. 625 |
Zohreh Yazdi, Khosro Sadeghniiat-Haghighi, Amir Mohammad Kazemifar, Arash Kordi, Siavash Naghipour DOI:10.4103/1319-2442.157431 PMID:26022045Restless leg syndrome (RLS) is a distressing sleep disorder that is commonly experienced by patients undergoing maintenance hemodialysis. The aim of this study was to assess the prevalence of RLS and its related factors among hemodialysis patients. This was an analytical cross-sectional study that was performed on hemodialysis patients of the Bu"Ali Hospital of Qazvin during 2009 and 2010. One hundred and twelve patients were selected by the census sampling method as the study sample. Data collection was performed using the Insomnia Severity Index (ISI), Pittsburg Sleep Quality Index (PSQI), Berlin, Epworth Sleepiness Scale (ESS) and International Restless Leg Syndrome Study Group criteria (IRRLS) questionnaires. Student's ttest and chi-square test were applied to analyze the collected data. RLS complaints were very common among patients on long-term dialysis therapy and were reported in about 42.9% of the patients. Patients with RLS had higher daytime sleepiness, insomnia complaints and poorer sleep quality. Percentage of patients in the high-risk group was higher in the RLS group. RLS symptoms appear to be correlated with age (P = 0.012) and use of sedative drugs (P = 0.035). RLS is common in dialysis patients and is associated with a higher prevalence of other sleep disturbances. Therefore, the effective assessment and management of this sleep disturbance has the potential to significantly enhance patient outcomes. |

Quality of life in patients on continuous ambulatory peritoneal dialysis in an African setting |
p. 631 |
Enajite I Okaka, Sagren Naidoo, Momina M Ahmed, Malcolm Davies, Saraladevi Naicker DOI:10.4103/1319-2442.157436 PMID:26022046To determine the quality of life (QOL) of patients on continuous ambulatory peritoneal dialysis (CAPD), we studied all the CAPD patients attending their monthly follow-up care clinics at three tertiary hospitals in Johannesburg by administering the World Health Organization QOL-Bref questionnaire. The patients were grouped according to age, duration of peritoneal dialysis and gender. Data were analyzed to determine the significant differences in the QOL scores among the subgroups. There were 114 patients [64 males (56.1%), with a mean age of 42.4 ± 11.3 years) and 38 healthy control subjects (22 males (57.9%), with a mean age of 42.1 ± 12.4 years]. Twenty-one patients (18.4%) had hemoglobin <10 g/dL, while 16 patients (14%) had serum albumin <3 g/dL. The mean QOL scores in the physical, psychological, social relationships and environment domains of the CAPD patients were 55.7 ± 15.0, 56.6 ± 16.4, 55.3 ± 24.7 and 56.3 ± 16.6, respectively. The CAPD patients had significantly lower QOL scores compared with controls, and those aged <30 years had better scores in the physical and psychological domains, gender and hemoglobin concentration. Serum albumin levels did not have a significant impact on the QOL of the CAPD patients. |

Nephrectomy in adults: Experience at the Korle Bu Teaching Hospital, Accra, Ghana |
p. 638 |
Mathew Y Kyei, George O Klufio, James E Mensah, Richard K Gyasi, Samuel Gepi-Attee, Kwadwo Ampadu DOI:10.4103/1319-2442.157438 PMID:26022047The objective of this study was to analyze nephrectomies performed in adults over a 12-year period at the Korle Bu Teaching Hospital, Accra and to compare our findings with reports from other institutions. In this retrospective study, medical records of 97 consecutive adult patients who underwent nephrectomy from January 2000 to December 2011 were reviewed. The parameters extracted included the patients' age, gender, indication for nephrectomy and the side of nephrectomy. Also considered were the histology of the nephrectomy specimen and the peri-operative mortality. The data were analyzed using the Statistical Package for Social Sciences for Windows (Version 19.0). Of the 97 nephrectomies performed, 62 were performed for suspected malignant renal tumors and 35 were performed for clinically benign renal conditions. Malignancy was confirmed in 85.5% (53/62) of the suspected cases. The mean age of this group was 52.2 ± 15.5 years and the male to female ratio was 1:0.9. Thirty-two tumors (60.4%) were in the right kidney and 21 (39.6%) tumors were in the left kidney; the mean tumor size was 16.8 ± 4.0 cm. The predominant presenting complaints included flank pain (67.9%), flank mass (50.9%) and hematuria (24.5%). In one case (1.9%), the renal mass was found incidentally. Among patients who had benign disease, non-functioning kidney due to renal cystic disease was the most common lesion (11/44; 25.0%). A peri-operative mortality rate of 3.1% was recorded. Our study suggests that malignant renal tumors constitute the main indication for nephrectomy in our institution. Non-functioning kidney due to renal cystic disease was the most common benign renal indication for nephrectomy. |
