    No full text
    Encapsulating peritoneal sclerosis (EPS) is a rare but serious complication seen in patients undergoing continuous ambulatory peritoneal dialysis (CAPD) or automated peritoneal dialysisAPD after prolonged duration on dialysis. Patients usally present with vague complaints of abdominal pain, vomitting, diarrhea, weight loss and change in peritoneal transport characte-ristics. High degree of suspicion is needed in PD patients who have been on dialysis for prolonged duration and have been using high-concentrated dialysis fluid. Mycobacterium fortuitum (MF) is a rapidly growing, non-tuberculous mycobacterium that has rarely been reported as a pathogen causing peritonits in patients on PD. We report a case of CAPD presenting with culture-negative peritonits, which, on specific culture, grew MF and, on radiological evaluation, showed diagnostic features of EPS

    Quality of Life (QoL) is a consistent and powerful predictor that affects the out-come in end-stage renal disease (ESRD) patients on dialysis. This study was undertaken to identify the factors that might predict QoL scores among ESRD patients on hemodialysis (HD). The study was conducted at three HD units in Saudi Arabia from January 2007 to January 2008. We studied 100 HD patients (53 males and 47 females) and used the SF-36 and KDQoL-SF forms covering six domains of QoL, namely physical, emotional, social, illness impact, medical and financial satisfaction, and overall general health. The mean age of the study patients was 47.5 ± 13.8 years and the mean duration of dialysis was 77.2 ± 75.5 months. The QoL scores were 45.8 ± 17.1 for general health, 53.1 ± 32.0 for physical QoL, 50.5 ± 14.8 for emotional QoL, 54.9 ± 18.1 for social QoL, 46.5 ± 13.7 for illness impact, and 45.9 ± 12.2 for the medical and financial domain. The total QoL score was 49.5 ± 13.7. The male patients had statistically significantly reduced QoL and younger patients had better QoL scores. The QoL scores revealed a decreasing trend with decreasing level of education; they were elevated among employed patients. Multiple linear regression analysis demonstrated that age, dialysis duration, and male sex were negative predictors of QoL score. We conclude from our study that QoL is reduced in all the health domains of HD patients. Older age, male gender, unemployment, and duration of dialysis adversely affected the QoL scores. Adequate management of some of these factors could influence patient outcomes

    Background: Viral hepatitis is a global health problem with a high mortality rate. End stage renal disease (ESRD) patients have a high prevalence of Hepatitis B and C virus infection. Present study was done to identify the prevalence and course of a new isolate Hepatitis G virus (HGV) infection in Saudi dialysis patients. Methods: The pattern of viral hepatitis infection (HBV. HCV and HGV) was investigated in 109 Saudi patients with ESRD and 100 healthy Saudi blood donors. Donated blood was tested for markers of Hepatitis B, C and G viruses. Liver functions were measured and blood picture and liver biopsies were also performed at regular intervals. Results: Out of the 109 ESRD patients 68 (62.4%) were positive for at least one viral marker: 59 (54.1%) were positive for HCV, six (5.5%) were positive for HGV and three (2.8%) were positive for HBsAg. Four of the six HGV positive patients were also co-infected with HCV. Eight (8%) of the blood donors were positive for at least one viral marker. Elevated ALT levels (>4 times normal) were recorded in four out of the six HGV-positive patients including three co-infected with HCV. Conclusions: Our results are in agreement with similar studies from different countries and also raise the question about the causal relationship between HGV and liver disease among dialysis patients

    To evaluate the diabetic complications and fate of diabetic nephropathy in Saudi population, we studied 184 diabetic nephropathy (DN) patients who were referred to nephrology clinic of King Khalid University Hospital, Riyadh, Saudi Arabia from January 2003-June 2006. The patients had mean age of 61.9 ± 13.1 years, included 128 (69.6%) males, and were followed up for a mean period of 10.2 ± 1.5 years. The mean duration of diabetes mellitus (DM) was 19.5 ± 5.8 years, and duration of nephropathy was 7.7 ± 3.3 years. Family history of DN was documented in 52 (28.2%) patients. At initial visit, the mean systolic blood pressure was 164 ± 14.5 mmHg, the mean diastolic blood pressure was 97.9 ± 10.4 mmHg. Thirty-seven (20%) patients had normal BMI, 88 (48%) were overweight, while 55 (30%) were obese. Mean creatinine clearance was 51.7 ± 26.3 mL/min, 24 hrs urinary proteins 1.99 ± 2.48 gm/day, HbA1C 9.2 ± 1.8 %, triglyceride 2.1 ± 1.3 mmol/L, and cholesterol 5.17 ± 1.54 mmol/L. Diabetic complications included angiography proven coronary artery disease in 106 (57.6 %) patients, stroke in 21 (11.4%), myocardial infarction (MI) in 27(14.6%), angina in 87 (47.2 %), retinopathy in 82 (44.5%), Blindness in 3 (1.6%), peripheral vascular disease in 121 (65.7%), Neuropathy in 123 (66.8%), hypertension in178 (96.7%), diabetic foot in 25 (13.5%), Amputation in 10 (5.4%), and end-stage renal disease in 70 (38%). Total of 13 (7.05%) patients died in the hospital. Thirty-seven percent of patients developed > 6 concomitant complications. 28% developed 5, 17% developed 4, and the rest developed < 3. DN was relatively refractory to therapy and progressive; 123 (66.8%) patients doubled their serum creatinine in 3.59 ± 2.88 years, 32 (17.3%) maintained stable renal function, 136 (73.6 %) deteriorated, and 12 (6.52%) improved. we conclude that the prevalence of diabetic complications is high among Saudi patients, and many had multiple complications. Baseline creatinine clearance and proteinuria, high systolic blood pressure, advanced age, and longer duration of diabetes were the most significant risk factors for developing complications

    No full text
    We describe here hydrothorax that occurred in a patient on continuous ambulatory peritoneal dialysis (CAPD) and highlight the problems of diagnosis and management. A 48 years-old man with history of obstructive uropathy secondary to urolithiasis was stared on CAPD when he reached end-stage renal failure. Two months later, he was admitted with two days history of shortness of breath on exertion and dry cough increasing in supine position. Chest examination was suggestive of right sided pleural effusion confusion confirmed by chest X-ray. Radioisotope Technetium <sup> 99m </sup> labeled albumin instilled through the peritoneal catheter was detected in the right pleural fluid confirming the peritoneo-pleural leak. The peritoneal dialysis (PD) was discontinued and the patient was switched to hemodialysis. The pleural effusion subsided and has not recurred for the following three years

    Serum cystatin C: A surrogate marker for the characteristics of peritoneal membrane in dialysis patients

    No full text
    To evaluate whether cystatin C levels can be a surrogate marker of creatinine clearance and reflect the characteristics of peritoneal membrane in dialysis patients, we performed peritoneal equilibration tests (PET) in 18 anuric adult chronic peritoneal dialysis (PD) patients with a mean age of 39.7 &#x00B1; 20 years. All the samples were analyzed for urea, creatinine, and cystatin C. Peritoneal transport, mass transfer, and peritoneal clearance of cystatin C were calculated. Correlation and regression analysis was done using cystatin C as a dependent variable and age, sex, height, weight, body surface area, and creatinine as independent variables. Cystatin C demonstrated a significant time dependent increase of dialysate concentration and decline in the serum concentrations during PET, and a strong correlation between serum creatinine and serum cystatin C concentrations(r: 0.62, p= 0.008). The trans-peritoneal clearance (mL/min/1.73 m 2 ) of cystatin C was related to its serum concentration and was similar to creatinine in its pattern but of smaller magnitude. Peritoneal mass transfer (mg/4 hr per 1.73 m 2 ) for cystatin C serum creatinine was 1.68 &#x00B1; 0.67 and 73.3 &#x00B1; 29.8, respectively. The dialysis/plasma D/P cystatin C concentration was &gt; 0.1 at 4 hrs of PET denoted high peritoneal transport, while the values of &lt; 0.1 denoted low transport type. We conclude that cystatin C follows the same pattern of peritoneal exchange as creatinine but the magnitude of transfer is many folds lower than creatinine. At present clinical utility of cystatin C in the evaluation of solute clearance is probably limited due to the minute amounts transferred across the membrane and the high renal clearance in the presence of residual renal function

    The aim of this study is to analyze the patients&#x2032; database of the Baxter&#x2032;s Training Peritoneal Dialysis Program (BTPDP) adopted at the Baxter Renal Education Center (BREC), Riyadh, Saudi Arabia in order to determine its effectiveness in the management, compliance, and outcome of the trained peritoneal dialysis (PD) patients. The study analyzes the database of the BTPDP, which includes the demographic data, duration of follow-up, complications, and outcome of the patients trained on PD between September 2003 and November 2007. Records of 376 patients with a mean age of 46.0 &#x00B1; 22.6 years were available in the database for analysis. Of them, 187 (49.7&#x0025;) were males, 312 (82.9&#x0025;) were trained at the BREC, 315 (83.8&#x0025;) were new PD patients, and 298 (79.3&#x0025;) were trained on automated PD (APD). The dropouts during the study period included 172 patients (46&#x0025;); 42 (24.4&#x0025;) were transplanted, 45 (26.2&#x0025;) switched to hemodialysis, 57 (33.1&#x0025;) died and 28 (16.3&#x0025;) were lost to follow-up. A comparison was made between the group trained at the BREC and the group trained at the hospital. There was an overwhelming adoption of BTPDP by the different hospitals during the study period (p &lt; 0.00001). There were 264 (84.6&#x0025;) patients trained on APD at the BREC vs. 34 (53.1&#x0025;) at the hospital (p &lt; 0.00001), and the patients trained at the BREC had significantly less dropouts than those trained at the hospital during the study period 135 (43.3&#x0025;) vs. 38 (59.4&#x0025;) respectively (p &lt; 0.02). The mean period of follow-up was significantly different between the patients trained at the BREC and those trained at the referring hospital (390 &#x00B1; 461 days vs. 679 &#x00B1; 779 days respectively (p &lt; 00000.8). Also, there was a trend for better technique survival after the second year, among the patients trained at the BREC. We conclude that the BREC model has increased the recruitment to PD, and helped in spreading this method of renal replacement therapy among patients. This model emphasizes the role of a designated training course by an expert team, and unifies the training standards. Furthermore, application of this model can be expanded nationwide and even to other countries

    This is the first report from Saudi Arabia studying the normal reference intervals in adult Saudi subjects and evaluating serum cystatin C as a prospective marker for the assessment of the glomerular filtration rate (GFR). Three hundred healthy adult Saudi subjects including 156 males (52&#x0025;) and 144 females (48&#x0025;), with a mean age of 31.21 &#x00B1; 9.82 years were prospectively studied to establish normal reference ranges for cystatin C. A total of 68.34&#x0025; of the study patients were in the age-group of 21-40 years. The mean serum cystatin C in the 300 healthy subjects was 0.751 &#x00B1; 0.11 mg/L (0.50 - 1.09), increasing gradually with age: it was 0.738 &#x00B1; 0.11 mg/L (0.51 - 1.09) in the age-group 21 - 30 years and 0.807 &#x00B1; 0.12 (0.51 - 1.09) among subjects who were &gt; 50 years of age. The mean serum cystatin C in females (0.778 &#x00B1; 0.118 mg/L) was significantly hig-her than in males (0.726 &#x00B1; 0.095 mg/L) (p &lt; 0.0001). The serum cystatin C level was within the defined reference range of 0.53 - 0.95 mg/L in 95&#x0025; of the subjects with a mean value of 0.74 &#x00B1; 0.097 mg/L, and was falling within the 95&#x0025; confidence interval of 0.73865 - 0.7637 mg/L, and with 98.84&#x0025; area under the curve (AUC). All the other renal function markers (urea, serum crea-tinine, calculated GFR, BMI) among the studied subjects were within the normal reference ranges for adult Saudi population. The serum cystatin C level had a significant correlation with the body mass index (BMI) (r = 0.155; p = 0.007) and a correlation with serum creatinine as well (r = 0.009; p = 0.873). It showed a negative correlation with calculated GFR as per Cockroft-Gault equation (r = - 0.101; p = 0.083)

    Appraising the outcome and complications of peritoneal dialysis patients in self-care peritoneal dialysis and assisted peritoneal dialysis: A 5-year review of a single Saudi center

    Our objective is to study the outcomes and complications of peritoneal dialysis (PD) including comparison of self-care PD with home-care assisted PD during a five-year period. A retrospective study of PD data at King Saud University-affiliated hospital in Riyadh from January 1, 2009, to December 31, 2013. One hundred and eleven patients were included (female 55%). The average age was 47.4 (1–83) years. Twenty-one (18.91%) patients were on continuous ambulatory PD and 90 (81.08%) on automated PD. The mean time on PD was 23.5 (3–60) months. At the end of five years, 47 (42.34%) patients were continuing on PD, 12 (10.81%) had renal transplant, 33 (29.73%) patients were transferred to hemodialysis, and two (1.8%) patients were transferred to other centers. Seventeen patients died during this period giving a mortality rate of 7.13 deaths/100 patient-year during the five-year period. Six patients died due to cardiovascular causes, while five had sepsis. There was one death each due to prostate cancer, hyperoxaluria, and toxic epidermal necrolysis. Three patients died suddenly at home. Peritonitis rate was one episode/35.28 patient/month or one episode/2.94 patient/year. We compared the results for patients doing the dialysis themselves [56 (50.45%)] “self-care PD” to 55 (49.5%) patients assisted by a family member or other caregivers “assisted PD.” We found no significant difference in the incidence of complications, technical outcome, mortality, and peritonitis episodes. However, we found a high prevalence of diabetes mellitus and significant increase in exit site infection in assisted PD. Our study suggests that PD patients in Saudi Arabia have a good overall outcome. Furthermore, assisted PD showed good patient and technique outcome

    Living Unrelated Renal Transplant: Outcome and Issues

    No full text
    Living unrelated transplantation (LURT) is emerging as a practical option in renal transplantation due to shortage of living related and cadaver donors. We report a six-years (December 1991 to December 1996) follow-up of 60 LURT patients. The majority of these patients (95&#x0025;) were transplanted outside the Kingdom of Saudi Arabia; 37 in India, 14 in Egypt, five in the USA and one in Pakistan. Only three patients (emotionally related) were transplanted in Saudi Arabia. Before transplantation, 50 (83.4&#x0025;) patients were on chronic hemodialysis, three (5&#x0025;) on peritoneal dialysis and three (5&#x0025;) were transplanted pre-emptively. Post-operatively, the majority of the study patients were on three drug immunosuppressive therapy. One and five year graft survival was 93.0&#x0025; and 59.6&#x0025;, while patient survival at one and three years was 93.7&#x0025; and 81&#x0025;, respectively. Surgical complications included lymphocele in 10&#x0025; of the study patients, urinary leak in 8.3&#x0025;, and bleeding from the vascular anastomosis in 6.6&#x0025;. There were eight episodes of acute rejection in eight (13.3&#x0025;) patients and all episodes were successfully treated; two patients required monoclonal anti-lymphocyte antibodies (OKT3). Eleven (18.3&#x0025;) patients developed chronic rejection, which resulted in the loss of ten (90&#x0025;) allografts. Infection was the commonest cause for hospital admission; urinary tract infection (UTI) being responsible for 40&#x0025; of admissions. Three patients had Cytomegalovirus pneumonia, one had Pneumocystis Carinii pneumonia and one had candida pneumonia. Two (3&#x0025;) patients developed Kaposi&#x2032;s sarcoma. We conclude that LURT can help in overcoming the shortage of organs for transplant, however, commercial transplantion in developing countries is associated with high morbidity and mortality
