New-onset diabetes after transplantation - Role of oral glucose tolerance test for diagnosis and study of risk factors |
p. 897 |
Manisha Sahay, Rakesh K Sahay, Girish Narayan, Anuradha DOI:10.4103/1319-2442.118068 PMID:24029252To determine the role of the oral glucose tolerance test in the early detection of new-onset diabetes after transplantation (NODAT) and to compare the various risk factors and insulin kinetics in the transplant patients, we studied 41 live-related renal allograft recipients who were not diabetic before transplantation. Immunosuppression included triple drug therapy (cyclosporine, azathioprine and steroids) and rejection episodes were treated with methyl prednisolone (30 mg/kg IV × 3 days). All the study patients were subjected to an oral glucose tolerance test (OGTT) at Day 90 post-transplant and classified as having normal glucose tolerance (NGT), impaired fasting glucose (IFG), impaired glucose tolerance (IGT) and NODAT as per the World Health Organization guidelines. Insulin levels were also determined at 0, ½ hour, 1 hour and 2 hours during OGTT. NODAT was noted in 29.2% of the study patients, IFG in 4.8% of the study patients and NGT in 65.8% of the study patients. All the groups had normal fasting plasma glucose, but higher than normal insulin levels, suggesting insulin resistance. The patients with overt NODAT had, in addition, low fasting insulin (insulin secretory defect). OGTT may be used for the early detection of NODAT. Although insulin resistance is detected in the majority of post-transplant patients, NODAT also reveals also an insulin secretory defect. |

Characteristics and prognosis of lymphoproliferative disorders post-renal transplantation in living versus deceased donor allograft recipients |
p. 903 |
Hossein Khedmat, Saeed Taheri DOI:10.4103/1319-2442.118069 PMID:24029253In this study, we compared the features and prognosis of post-transplantation lymphoproliferative disorders (PTLD) occurring in living donor recipients with those of deceased donor kidney transplant patients. A comprehensive search was performed for finding studies reporting data of PTLD in living and deceased donor renal recipients in the Pubmed and Google scholar search engines. Finally, international data from 14 different studies were included in the analysis. Overall, 122 renal recipients with PTLD were entered into this analysis. Chi square test showed that renal recipients from living donors significantly less frequently represented any remission episodes during the course of their disease (41% vs. 63%, respectively; P = 0.05). Living donor renal recipients were significantly more likely to develop metastasis in comparison with deceased donor recipients (64% vs. 23%, respectively; P = 0.035). Histopathological evaluations were comparable between the two patient groups. Survival analysis did not show any difference between the patient groups, even when patients were adjusted for the type of immuno-suppression. The mortality rate of the transplant patients with PTLD was 55.3% and the 1- and 5-year patients survival rates were 50% and 37%, respectively, for the deceased donor renal recipients compared with 60% and 34%, respectively, for the living donors group. We conclude that living donor kidney transplant recipients who develop PTLD have a higher rate of metastasis and a lower rate of remission episodes. Further prospective studies with a large patient population are needed to confirm our results. |

Safety and efficacy of everolimus in chronic allograft nephropathy |
p. 910 |
Uttara Das, Kaligotla Venkata Dakshinamurty DOI:10.4103/1319-2442.118074 PMID:24029254Chronic allograft nephropathy (CAN) is a major cause of late kidney allograft loss. Everolimus, a novel proliferation signal inhibitor, ameliorates CAN by its antiproliferative or apoptosis-enhancing effects. This study aims to evaluate the safety and efficacy of everolimus in renal transplant recipients with calcineurin inhibitor (CNI) withdrawal either due to CAN or cal-cineurin inhibitor toxicity (CNIT). A total 21 patients with CAN or CNIT converted from CNI to everolimus were prospectively studied from 2006 to 2009. There were 19 males and two females, with a mean age of 32.9 ± 10.7 years. Eight patients had chronic interstitial nephritis, three had diabetes mellitus, nine had end-stage renal disease and one had focal segmental glomerulosclerosis as native kidney disease. The mean duration of dialysis was 10.7 ± 7 months. 57.2% of the patients had CAN and 42.8% had CNIT. Everolimus was started within six months of post-transplantation in six patients, within 6-12 months in two patients, within 1-2 years in four patients and after more than 2 years in nine patients. The mean dose at first month was 1.25 mg/day, at six month was 1.028 ± 0.3 mg/day and at 12 th month was 0.97 ± 0.2 mg/day, with a mean trough level of 6.35 ± 3 ng/dL, 5.18 ± 3 ng/dL and 6.43 ± 1.7 ng/dL, respectively. At the 12 th month, serum creatinine declined from 2.07 ± 0.58 mg/dL to 1.65 ± 0.81 mg/dL. The mean calculated glomerular filtration rate improved from 40.85 ± 8.8 mL/min to 56.84 ± 11.4 mL/min. No major side-effects were observed. Everolimus along with mycophenolate mofetil or azathioprine and prednisolone as a maintenance immunosuppressive therapy was found to be effective and safe in patients with CNIs withdrawal either due to CAN or CNIT. |

Effect of chronic hepatitis C virus infection on bone mineral density in pediatric renal transplant recipients |
p. 917 |
Amr El-Husseini, Alaa Sabry, Rashad Hassan, Mohamed Sobh DOI:10.4103/1319-2442.118078 PMID:24029255Previous studies have suggested that loss of bone mineral density (BMD) frequently occurs in patients with chronic viral liver disease, presenting with histologically proven liver cirrhosis. However, little is known about the occurrence of bone disease in non-cirrhotic patients with chronic hepatitis C virus (HCV) infection. Furthermore, to the best of our knowledge, such an effect has never been studied in pediatric renal transplant recipients. The aim of this study was to assess the impact of HCV infection on BMD in pediatric renal transplant patients. We performed a cross-sectional study to assess BMD and HCV in 83 patients who received living renal allotransplants in the Mansoura Urology and Nephrology Center between 1983 and 2005. The mean age of the study patients at transplantation was 13.4 ± 2.9 years; there were 53 males (63.9%) and 30 females (36.1%). BMD was studied using dual energy X-ray absorptiometry at various time intervals up to 16 years after transplantation (mean duration after transplantation was 48 ± 34 months, range 12- 192 months). Thirty-three patients tested positive for HCV-RNA (positive group) and 50 patients were negative (negative group), and we compared the BMD between the two groups. Before transplantation, 58 patients (69.9%) were on maintenance hemodialysis, four (4.8%) were on peritoneal dialysis and 21 (25.3%) were pre-emptive. Among the HCV-positive group, six patients (18.2%) had osteoporosis, 17 (51.5%) had osteopenia and ten (30.3%) had normal BMD. In the HCV-negative group, ten patients (20.0%) had osteoporosis, 24 (48.0%) had osteopenia and 16 (32.0%) had normal BMD. The difference was not significant between the two groups (P = 0.9). Also, there was no significant difference in the serum creatinine, calcium, phosphorus and parathormone levels between the two groups. Our results suggest that chronic HCV infection does not pose a risk for low BMD in pediatric renal transplant recipients. |

Progressive pulmonary hypertension: Another criterion for expeditious renal transplantation |
p. 925 |
Yogesh N.V. Reddy, Deepika Lunawat, Georgi Abraham, Milly Matthew, Ajith Mullasari, Prethivee Nagarajan, Yuvaram N.V. Reddy DOI:10.4103/1319-2442.118080 PMID:24029256The aim of this retrospective study was to compare the prevalence of pulmonary hypertension in a cohort of patients with end-stage renal disease (ESRD) prior to and following renal transplantation and to identify the possible risk factors. Of the 425 renal transplantations performed between 2001 and 2007, Doppler echocardiographic findings were available in 124. The echocardiographic data, collected both pre- and post-transplant, included the pulmonary artery pressure (PAP), ejection fraction and left ventricular hypertrophy. The data analyzed included age, gender, hypertension, diabetes, smoking status, along with blood urea, creatinine, glomerular filtration rate, hemoglobin, hemodialysis duration, urine albumin, arterio-venous access and body mass index (BMI). Chi-square test was used for discrete variables and ANOVA was used for continuous variables. Of the patients studied, males comprised 72%; the mean age was 43.3 ± 13.02 years; 87% were hypertensive, 30% were diabetic and 4% were smokers. Statistical analysis revealed a significant reduction of the PAP, irrespective of its severity, following renal transplantation (P <0.05). The PAP had no significant correlation with any of the parameters analyzed, with the exception of BMI (P <0.05). Our study suggests that the PAP gets reduced in patients with ESRD after renal transplantation. |

Relation of middle molecules levels and oxidative stress to erythropoietin requirements in high-flux versus low-flux hemodialysis |
p. 930 |
Hala S El-Wakil, Abla A Abou-Zeid, Iman E El-Gohary, Nahla A Abou El-Seoud DOI:10.4103/1319-2442.118082 PMID:24029257The objective of this study is to investigate the serum beta-2-microglobulin (B2MG) and advanced oxidation protein products (AOPP) as middle molecule uremic toxins and protein carbonyl (PCO) as oxidative stress marker in uremic patients undergoing high-flux versus low-flux hemodialysis (HD) and to correlate their levels to the erythropoietin requirements for those patients. Twenty patients on chronic low-flux HD were recruited in the study. At the start of the study, all patients underwent high-flux HD for eight weeks, followed by low-flux HD for two weeks as a washout period. The patients were then subjected to another eight weeks of low-flux HD. Blood samples were obtained at the beginning and at the end of the high-flux period and the low-flux period. The mean erythropoietin dose for patients using high-flux HD was significantly lower than that for low-flux HD (P = 0.0062). Post-high flux, the B2MG and PCO levels were significantly lower than the pre-high-flux levels (P = 0.026 and 0.0005, respectively), but no significant change was observed in AOPP (P = 0.68). Post-low flux, the B2MG, AOPP and PCO were significantly higher than the pre-low-flux levels (P = 0.0002, 0.021 and <0.0001, respectively). Post-low flux, the B2MG and PCO were significantly higher than the post-high-flux levels (P <0.0001), but no significant difference was observed in AOPP (P = 0.11). High-flux HD results in reduction of some of the middle molecule toxins and PCO levels better than low-flux HD, and is associated with a better response to erythropoietin. |

Clinical presentation and etiology of osteomalacia/rickets in adolescents  |
p. 938 |
Mohammad A Hazzazi, Ibrahim Alzeer, Waleed Tamimi, Mohsen Al Atawi, Ibrahim Al Alwan DOI:10.4103/1319-2442.118087 PMID:24029258This study was conducted to determine the causes and clinical presentations of osteomalacia/rickets in adolescents seen at the King Abdulaziz Medical City (KAMC), Riyadh. Because osteomalacia and rickets constitute the same entity, the term osteomalacia will be used for future discussion. A retrospective file review was performed on all adolescents (10-16 years) with osteomalacia, defined as alkaline phosphatase levels ≥500 IU/L, seen at the KAMC, Riyadh, from 2000 to 2006. We recorded the signs and symptoms, dietary history and amount of sun exposure at presentation. A total of 135 patients were found to fit the inclusion criteria for the study. Of them, 57 had nutritional causes, with a mean age of 13.2 years, and included 32 females. At diagnosis, 22 patients were found to have bone pain, 10 had bone deformities, eight had pathological fractures and 17 were asymptomatic. Secondary causes for osteomalacia were found in 59 cases who had liver and renal disease and in 19 other patients who were on medications such as anticonvulsants and steroids, which are known to cause osteomalacia. Our study indicates that osteomalacia is a significant health burden that deserves special attention. Bone pain is the most common presenting symptom at diagnosis. Because of the high risk of osteomalacia associated with the use of anticonvulsants and steroids, it is advised that all patients on these drugs should be routinely screened for secondary osteomalacia. |

Peritubular capillaries and renal function in pediatric idiopathic nephrotic syndrome |
p. 942 |
Kamaljeet Singh, Ruma Ray, Alok Sharma, Ruchika Gupta, Arvind Bagga, Amit K Dinda DOI:10.4103/1319-2442.118091 PMID:24029259Nephrotic syndrome (NS) is a common renal disorder with significant tubulo-interstitial damage due to the combined effects of proteinuria and obstruction of efferent blood flow. Peritubular capillary (PTC) loss has also been correlated with interstitial fibrosis. This study included 30 pediatric cases of idiopathic NS. Clinical details, including biochemical parameters, were recorded and renal biopsy slides were reviewed for histological features. PTCs were highlighted using anti-CD34 antibody and quantified with the help of image analysis software. Postmortem kidney biopsies from seven children were taken as controls for quantification of PTCs and interstitial fibrosis. Wherever possible, as ultrastructural examination of the renal biopsy was performed. Appropriate statistical methods were applied. Patients with minimal change disease (MCD) had lower serum creatinine as compared with those with focal and segmental glomerulosclerosis (FSGS). Similarly, tubular atrophy and interstitial fibrosis were significantly lower in MCD than in FSGS. PTC density was lower in all groups of NS as compared with the controls. Biopsies with FSGS had a lower PTC density compared with both MCD and mesangioproliferative glomerulonephritis. PTC density showed a negative correlation with serum creatinine and degree of proteinuria. PTC loss appears to play an important role in the development of renal biopsy changes in pediatric NS. This aspect of the renal vasculature requires further study in idiopathic NS. |

Incidence and clinical outcome of renal amyloidosis: A retrospective study  |
p. 950 |
Emad Abdallah, Emam Waked DOI:10.4103/1319-2442.118094 PMID:24029260The kidneys are affected in almost all patients with amyloid A in secondary amyloidosis (AA) amyloidosis but less frequently in immunoglobulin light chains in primary systemic amyloidosis (AL) amyloidosis. In this study, we present the incidence, etiology, clinical manifestations, biochemical features and clinical course of renal amyloidosis. We conducted a retrospective study on a group of 40 cases with renal biopsy-proven amyloidosis. They constituted 2.5% of the total cases of renal biopsies performed in the Theodor Bilharz Research Institute, Cairo, Egypt, during the period from February 2003 to May 2009. The mean age (30 males, ten females) was 36.51 ± 10.32 years. Thirty-two of the cases had secondary AA amyloidosis and eight cases had primary AL amyloidosis. The causes of secondary amyloidosis were as follows: 12 (30%) familial Mediterranean fever (FMF), eight (20%) pulmonary tuberculosis, four (10%) chronic osteomyelitis, four (10%) bronchiectasis, three (7%) rheumatoid arthritis and one (2%) rheumatic heart disease. The eight cases of primary AL amyloidosis comprised of five cases that were associated with myloma (13%) and three (8%) cases that were idiopathic. Among the 23 patients with AA amyloidosis, after six months of treatment with colchicine, the proteinuria improved, serum albumin level increased and edema disappeared in 13 patients. In four cases of AA amyloidosis who were clinically and biochemically normal after cholchicine therapy, a second renal biopsy disclosed decreased amyloid deposition compared with the first biopsy. In the three renal transplanted patients who had amyloidosis secondary to FMF and were treated with colchicines, AA amyloidosis did not recur in the transplanted kidney. It might be possible that in AL amyloidosis, treatment with methotrexate, melphalan and prednisolone may improve survival. The incidence of renal amyloidosis is increasing and colchicine can be used in secondary amyloidosis as it may have an effect on reducing the production of the amyloid precursor proteins and in reducing proteinuria. |

Role of expression of endothelin-1 and angiotensin-II and hypoxia-inducible factor-1α in the kidney tissues of patients with Diabetic Nephropathy |
p. 959 |
Shrestha Kumar Duwal Sagar, Cuicui Zhang, Qing Guo, Run Yi, Lin- Tang DOI:10.4103/1319-2442.118098 PMID:24029261The objective of this study was to detect the expression of Angiotensin-II (Ang-II), Hypoxia-inducible factor-1α (HIF-1α) and Endothelin-1 (ET-1) in the kidneys of patients with diabetic nephropathy (DN) and to investigate their relationship with renal interstitial fibrosis (RIF). A total of 47 paraffin specimens of patients with DN and six controls were enrolled in this study, and all were diagnosed by histopathology. We studied the expressions of Ang-II, HIF-1α and ET-1 by immuno-histochemical staining and the level of RIF by Masson staining. The following results were found: (a) RIF existed in the kidneys of patients with DN, (b) the expressions of Ang-II, HIF-1α and ET-1 were lower in the control group but increased significantly in the DN group, (c) the expression of Ang-II, HIF-1α and ET-1 in tubular epithelial cells directly correlated with RIF (r s = 0.659, 0.633, 0.716, P <0.01) and (d) the expression of Ang-II, ET-1 and HIF-1α in the kidneys of patients with DN positively correlated with serum creatinine (Scr) levels (r s = 0.391, 0.594, 0.531, P <0.01) but they did not correlate with the 24-h urinary protein, blood glucose and serum albumin levels. These results provide new insights suggesting that over-expression of Ang-II, HIF-1α and ET-1 promote the progression of RIF in DN. Thus, targeting reduction in the expression of Ang-II, HIF-1α and ET-1 can delay RIF in DN. Further studies are needed to validate this observation. |

A kink in transplantation: A rare cause of early graft dysfunction |
p. 965 |
Vemuru Sunil K Reddy, Sandeep Guleria, Shamna Mahmood Abdullah, Ravi Bansal DOI:10.4103/1319-2442.118103 PMID:24029262Kink of the transplant renal artery is a rare yet correctable cause of early graft dysfunction. We describe a 35-year-old male patient with end-stage renal disease who underwent live, related renal transplantation with end-to-side anastomosis of the graft vessels with the external iliac vessels. He had oliguria and uncontrolled hypertension in the post-operative course and was found to have a parvus tardus waveform on Doppler ultrasound and an acute angled kink of the renal artery on angiography. After failure of initial attempts at per cutaneous transluminal renal angioplasty, the patient was re-explored and the graft renal artery was anastomosed with the internal iliac artery. The patient had a steady recovery and was discharged with a good renal function. A kinking of the renal artery should be excluded when early graft dysfunction is associated with a parvus tardus waveform. |

Late response to rituximab in a dialysis patient with severe lupus nephritis
|
p. 976 |
Magdi M Hussein, Jaap M Mooij, Najla Al Malki, Tarek M Demerdash DOI:10.4103/1319-2442.118101 PMID:24029264Although recently completed controlled trials failed to demonstrate a significant effect of rituximab on the clinical outcome in non-renal and renal lupus, there is growing evidence from case reports and open-label trials that the use of this medication is successful in certain subgroups of patients including refractory cases and helps in reducing the dose of steroids. We present a 26-year-old female who failed to respond to a long-course treatment with prednisolone, cyclophosphamide, mycophenolate mofetil and azathioprine and who went on to develop end-stage renal disease requiring commencement of regular maintenance hemodialysis. Ten days before starting dialysis, she was given rituximab, and a second dose was given 17 days after starting dialysis. After 7 months on dialysis, the patient began to regain kidney function and is now off dialysis for 11 months. To the best of our knowledge, this is the first case report of a lupus patient on dialysis treated with rituximab in whom dialysis could be stopped and who remained off this therapy up till now, after an observation period of 1 year. |

We present a case of a ureterocele containing a calcified stone in an 8-year-old girl. The diagnosis was made with radiological investigations (intravenous pyelogram, ultrasonography and, eventually, voiding cystourethrogram). Meatostomy and calculus extraction, or open surgery in more complicated cases, are the treatments of choice. |

Extragenitourinary retroperitoneal primary hydatid cyst: a rare cause of bilateral lower ureteric obstruction and unilateral limb edema
|
p. 991 |
Amit Goel, Punit Tiwari, Pramod Kumar Sharma, Suresh Kumar, Anup Kumar Kundu DOI:10.4103/1319-2442.118092 PMID:24029268Hydatid cyst is an endemic disease in our country. Most commonly, it occurs in the liver and lungs. Bilateral hydroureteronephrosis is one of the rare presentations of hydatid disease. Herein, we are reporting an unusual case of hydatid disease where the primary mode of presentation was external iliac vein compression with chronic renal failure because of bilateral ureteric involvement. The patient was treated with bilateral double-J stenting to improve the renal function and operated later for removal of hydatid cyst under albendazole drug treatment. |

Therapeutic effect of oral nicotinamide on refractory uremic pruritus: A randomized, double-blind study |
p. 995 |
Mohammad Omidian, Ahmad Khazanee, Reza Yaghoobi, Ali Reza Ghorbani, Nader Pazyar, Seyed Seifollah Beladimousavi, Mahmoodreza Ghadimi, Alireza Mohebbipour, Amir Feily DOI:10.4103/1319-2442.118070 PMID:24029269To determine the efficacy of oral nicotinamide with placebo to ameliorate uremic pruritus (UP), we conducted a prospective, randomized, double-blind, 4-week study in 50 chronic kidney disease patients with refractory UP. The patients were randomly allocated to nicotinamide tablet 500 mg twice/day or placebo. All anti-pruritic agents were discontinued at least two weeks before the study. All the patients completed the period of the study and their severity of pruritus was evaluated before the start of the study and at the end of each week for four weeks by using a traditional Visual Analogue Scale and a modified questionnaire method (pruritus score). The average pruritus score before administration of oral nicotinamide in the study group and that in the placebo group was 2.96 ± 0.45 and 2.72 ± 0.37, respectively. In the nicotinamide group, the average score of pruritus gradually reduced to 1.29 ± 1.08 and in the placebo group it gradually decreased to 1.52 ± 1.61 at the end of the fourth week. There was no significant difference between the reductions of pruritus in both groups, but the interaction effect using a linear mixed model was significant between drug and time (P <0.026). We conclude that increasing the time of application of nicotinamide sodium to more than four weeks may be more effective than placebo in reducing itching in uremic patients. |

Pediatric versus adult kidney transplantation activity in Arab countries |
p. 1031 |
Bassam Saeed DOI:10.4103/1319-2442.118089 PMID:24029280The objective of this study was to evaluate the current activity of pediatric versus adult kidney transplantation activity in the Arab world. A questionnaire was mailed to all kidney transplant centers in Arab countries to collect data on the kidney transplant activity in a recent single year. Three thousand three hundred and nine kidney transplants were performed in one year, with a transplant rate of 9.5 per million populations (PMP); 298 were performed for children with a pediatric kidney transplant (PKT) rate of 0.87 PMP, which is much lower than that of developed countries where it mostly ranges from 5 to 10. The pediatric share of all transplants is 9%, which is twice as high as that of European children. Kidney transplant programs in most Arab countries rely exclusively on living donors as there is a severe shortage of deceased donors. 93.5% of all transplants, combined adult and pediatric, were from living donors. Deceased transplant activity in Arab countries accounts for 14-31% of all transplants in the three countries with deceased donor programs. Of the 212 adult and pediatric transplants that were performed from deceased donors in eight countries, only 29 cases were for pediatric recipients. Deceased PKT is available in the Kingdom of Saudi Arabia (KSA), Tunisia and Kuwait. Surprisingly, the PKT share was not better in the countries with higher overall kidney transplant rate and or in those where deceased transplant was available. PKT is still inactive in most Arab countries and mostly relies on living donors. The lack of well-developed deceased donor programs is the main issue to be addressed. |

Allograft biopsy in kidney transplant recipients in the medical city of Baghdad |
p. 1039 |
Ala A Ali, Ali J.M. Al-Mudhaffer, Qais Al-Taee, Suad Al-Windawi DOI:10.4103/1319-2442.118090 PMID:24029281To determine the safety and efficacy of the practice of renal allograft biopsy and verify its impact on the management of kidney transplant patients presenting with graft dysfunction, we studied 50 renal allograft biopsies of 47 adult patients (38% males, mean age 32.4 ± 11 years) performed in the medical city complex from November 2008 to April 2011. All the biopsies were performed with a guidance of ultrasound. The procedure, complications, histological diagnoses and impact of the biopsy data on patients' management were recorded. Thirty percent of the biopsies were performed in the first 12 months post-transplantation and 24% were performed after the 60 th month. Adequate biopsy was achieved in 76% of the patients, with a 96% safety rate. Acute rejection was diagnosed in 38% of the biopsies and chronic allograft nephropathy in 38%, and they were the most common histological patterns in the study. The results of allograft biopsies positively impacted the management strategy in all study groups. Renal allograft biopsy was a useful and a relatively safe tool for the diagnosis of acute and chronic graft dysfunction in our experience. |

Barriers to kidney transplantation among adult Sudanese patients on maintenance hemodialysis in dialysis units in Khartoum state |
p. 1044 |
Hisham H Abdelwahab, Mazin M. T. Shigidi, Lamees S Ibrahim, Alyaa K El-Tohami DOI:10.4103/1319-2442.118093 PMID:24029282Kidney transplantation remains the preferred modality of treatment for patients with end-stage renal disease. In Sudan, kidney transplantation accounted for 28% of the total provided renal replacement therapies. A cross-sectional, hospital-based study was conducted in hemodialysis (HD) units in Khartoum State during the period from September 2010 to January 2011. It aimed to determine the main reasons for the currently low renal transplantation rate. Data were obtained by direct interviewing using a specifically pre-coded and pre-tested questionnaire following a pilot study. A total of 462 adult HD patients were randomly selected from the various HD units in Khartoum State; these patients accounted for 16.9% of the total HD population in Khartoum State. The mean age of the study patients was 48.5 ± 23.6 years and 312 (67.5%) were males. Upon interviewing, only 316 patients (68.4%) said that they had been counseled for kidney transplantation. One hundred and twenty-two patients (26.4%) were on the active transplant list; of these, 50% preferred to have their kidney transplantation performed abroad, mostly due to the availability of commercial transplantation and/or a presumed better outcome. The low renal transplantation rate was due to financial constraints in 112 patients (24.2%), lack of medical fitness in 97 patients (21%) and absence of a suitable kidney donor in 92 patients (20%), while 56 patients (12%) were still having misperceptions regarding transplantation and preferred to continue on dialysis. To improve the kidney transplantation rate in Khartoum State, the Sudan program for organ transplantation is expected to take more initiatives to promote and improve the outcome of kidney transplants inside the country and, accordingly, regain the patients' confidence on the health system. |

Patterns of childhood nephrotic syndrome in Aljouf region, Saudi Arabia |
p. 1050 |
Abdulaziz Alhassan, Waleed Z Mohamed, Mohamed Alhaymed DOI:10.4103/1319-2442.118096 PMID:24029283To determine the patterns in children with nephrotic syndrome (NS) in our region, we retrospectively studied 25 nephrotic patients evaluated and followed-up in the hospitals of the Aljouf region in Saudi Arabia. The male to female ratio was 2:1. The incidence of idiopathic NS was two to six cases per 100,000 children/year, while the prevalence was 12 cases per 100,000 children. Five patients presented with hypertension, seven (28%) with respiratory tract infection, three (12%) with tender abdomen, two (8%) with gross hematuria, one (4%) with thrombosis of renal veins with seizure and shock and the remaining seven presented to the hospital without complications. Twenty-three (92%) patients were sensitive to the first steroid course and two (8%) patients were steroid resistant, and both of them proved to have focal segmental glomerulosclerosis (FSGS) on biopsy. Of those who responded, six (24%) patients remained in remission, while 17 (68%) patients became steroid dependant. Of those who were diagnosed as steroid dependent, three patients were biopsied and one of them was diagnosed as FSGS, while the remaining two had minimal change glomerulonephritis. Regarding steroid-dependent patient relapses, seven (41%) patients showed infrequent relapses and ten (59%) patients had frequent relapses. We conclude that the patterns of NS and the response to treatment observed in this study did not differ significantly from studies from other places in the world. |

Idiopathic urolithiasis in Tunisian children: A report of 134 cases |
p. 1055 |
A Alaya, R Sakly, A Nouri, MF Najjar, M Belgith, R Jouini DOI:10.4103/1319-2442.118099 PMID:24029284We evaluated the metabolic and the nutritional aspects of 134 urolithiasis children in order to outline the characteristics of idiopathic urolithiasis in children. This prospective study group of 134 children (56 females, 78 males) with renal calculi was evaluated. The age range of the patients was six months to 16 years. A dietary survey was performed on every child. All patients were investigated with respect to stone localization and serum and urine risk factors. Statistical analysis of data was carried out using software SPSS 11.0 for Windows. Hypercalciuria was the most common risk factor detected in this group (28.3%). A decrease of water intake was noted in all age groups, especially in the rural area (549.6 mL/day vs. 1150.6 mL/day), and there was an increase in animal protein intake in 17 cases (mean: 1.9 g/kg). In addition, increased intake of starchy foods and food with high oxalate content (sorgum) were detected in the ten to 16 years age group (51%) of our study. Calcium oxalate monohydrate represents the principal component of idiopathic stone (58.2%), which is more frequent in children (68%) than in infants (51.7%) (P <0.02). The major etiology of idiopathic urolithiasis highlights the influence of dietary habit in stone formers in our country. The increased occurrence of calcium oxalate stones in school age children confirms the change in the etiology of urolithiasis according to age. |

Characteristics of atheromatous renovascular disease in Dubai: A single-center experience |
p. 1062 |
Wael Lateef Jebur, Khalid Abdulla, Sohrab Tomaraei DOI:10.4103/1319-2442.118102 PMID:24029285To determine the characteristics of atherosclerotic renal artery stenosis (ARAS) in a cohort of patients who attended the Nephrology Department of NMC Specialty Hospital in Dubai from 2006 through 2010, including their clinical and investigational features and their response to various remedial modalities, we studied 20 patients with a diagnosis of ARAS based on magnetic resonance angiography. Three (15%) patients developed acute renal failure (ARF) after the initiation of angiotensin converting enzyme inhibitors or angiotensin II receptor blockers and 13 (65%) patients presented with chronic kidney disease (CKD) of either ischemic nephropathy or nephroangiosclerosis etiology. Four (20%) patients presented with resistant arterial hypertension (RAH). Plasma renin activity was elevated in all the patients. Fifteen (75%) patients were diabetics. We conclude that CKD was the main presentation of ARAS followed by RAH and ARF in our study. Diabetes Mellitus was the main risk factor for ARAS found in our study. |

Epidemiological patterns of chronic kidney disease in black African elders: A retrospective study in West Africa |
p. 1068 |
Sidy Mohamed Seck, Ibrahima Mbemba Diallo, Seydina Issa Laye Diagne DOI:10.4103/1319-2442.118104 PMID:24029286Chronic kidney disease (CKD) is frequently described in elders. This study describes the epidemiological patterns of patients ≥60 years old admitted in our department during one year. The prevalence of CKD was 10.8% (60/552). The mean age of the patients was 70.5 years (60-84 years) and the sex ratio (male:female) was 1.08. The mean serum creatinine level was 7.10 mg/dL (1.31-25.0 mg/dL) and more than two-third of the patients presented CKD stage 4-5. Causes of CKD were dominated by hypertension (30%) and diabetes (25%). Prevalence of inpatients aged 60-69 years old was higher than in those ≥80 years old but lower than that in patients aged 70-79 years. At admission, 83.3% of the patients were hypertensive, 75% were anemic and 13% presented proteinuria. The main co-morbidities associated with CKD were neoplasms (17% of cases), chronic heart disease (15% of cases) and pneumonia (15% of cases). Furosemide was prescribed in 55% of the patients, calcium channel blockers in 23% of the patients and ACE inhibitors in 20% of the patients. Renal replacement therapy was not performed for any patient. Evolution was favorable in the majority of patients (77%), but 23% died mainly because of uremia and infections. |
