Saudi Journal of Kidney Diseases and Transplantation 2019 30(4):755-763

The aim of this study was to determine the relationship between the presence of carotid artery calcification (CAC) and pulp stone (PS). A total of 60 chronic hemodialysis (HD) patients (30 CAC positive, 30 CAC negative) participated in this study. The mean age of patients was 54.7 ± 16.4 years, and 32 (53%) of them were male. CAC was defined as the presence of heterogeneous nodular opacities in the soft tissue in C3–C4 intervertebral area. Panoramic radiographs of the patients were evaluated for CAC and PS by two oral and maxillofacial radiologists. PS was evaluated in all healthy, decayed, and restored teeth except the third molar teeth, in the coronal, sagittal, and axial planes. The Statistical Package for the Social Sciences (version 20.0; SPSS, Inc., an IBM Company, Chicago, IL, USA) was used. A probability P <0.05 was considered statistically significant. The prevalence of PS in this study was 30% (18 patients) all group. A total of 1324 teeth were analyzed and PS was detected in 237 teeth (17.9%). The occurrence of PS in teeth in CAC-positive group (10 patients, 17.2% of 654 teeth) was similar to that in CAC-negative group (8 patient, 18.3% of 670 teeth). There was no statistical correlation between CAC and PS in chronic HD patients (P = 0.08). In the subgroup analysis, the presence of diabetes (P = 0.003), parathormone level (P = 0.02), calcium × phosphorus product (P = 0.04), and C-reactive protein levels (P = 0.002) were higher, and duration of HD (P = 0.03) was significantly longer in patients with CAC-positive and PS. In chronic HD patients, the presence of PS was not a strong predictor for the presence of CAC.

Infective endocarditis (IE) is a life-threatening condition with high morbidity and mortality. The current IE guidelines recommend antibiotic prophylaxis only in patients with certain cardiac conditions and before certain dental procedures. However, there is not enough data about solid organ transplant (SOT) recipients. In this study, we aimed to investigate the IE prophylaxis in general dental and periodontal surgical procedures among our SOT recipients. Medical records of 191 SOT recipients (32 liver transplant recipients, 54 heart transplant recipients, and 105 kidney transplant recipients) who were admitted to our hospital between January 2016 and January 2018 were evaluated. A total of 65 patients who underwent dental procedures were included in the study. We investigated the adequacy of IE prophylaxis according to the current guidelines. Two groups were created according to whether they received antibiotic prophylaxis or not. The mean age was 44.2 ± 13.6 years, and 66.1% were male. The majority of patients (67.6%) received antibiotic prophylaxis. The most commonly used antibiotic was amoxicillin (48.8%). Among the procedures, 23.1% were classified as invasive and 76.9% were classified as noninvasive. No complication was observed after invasive and noninvasive dental procedures. There were no complications in both antibiotic prophylaxis and no-prophylaxis groups. According to our results, IE prophylaxis has been used appropriately in SOT recipients in our center. No serious infection has been reported. In addition, no complication due to antibiotic use was also observed.

Nephrotic syndrome (NS) is one of the most common kidney diseases seen in children. It is a disorder characterized by severe proteinuria, hypoproteinemia, hyperlipidemia, and generalized edema resulting from alterations of permeability at the glomerular capillary wall. Endothelin-1 (ET1) has a central role in the pathogenesis of proteinuria and glomerulosclerosis and has a role in assessment of the clinical course of NS in children. This study aims to investigate the relationship between ET1 serum level and the response to steroid therapy in children with primary NS. Serum ET1 levels were evaluated in 55 children with NS. They were classified into two groups: 30 patients with steroid-sensitive NS (SSNS) and 25 patients with steroid-resistant NS (SRNS). The SSNS group was further divided into infrequent-relapsing NS (IFRNS) and steroid-dependent NS (SDNS), while the SRNS group was subdivided into two groups according to renal pathology. ET1 levels were significantly higher in the SRNS group (52.5 ± 45.8 pg/dL) compared to the SSNS group (18.3 ± 17 pg/dL) (P <0.001). Furthermore, ET1 levels were significantly higher in SDNS (54.3 ± 18.6) compared to IFRNS (11.9 ± 7.8, P = 0.001). There was no statistically significant difference in ET1 levels between minimal change disease group and focal segmental glomerulosclerosis group, (P = 0.28). Serum ET1 can be considered as a predictor for response to steroid therapy.

Therapeutic plasma exchanges (TPE) is considered as one of the treatment modalities that is used in systemic autoimmune diseases. This study aimed to describe the early and late effect of TPE in patients with systemic lupus erythematosus (SLE) and antineutrophil cytoplasmic antibody-associated vasculitis (AAV) presented with acute kidney injury (AKI). Retrospective study comprised patients with SLE and AAV with AKI seen between January 2000 and June 2014 at King Faisal Specialist Hospital and Research Center in Riyadh. All patients underwent TPE. Retrospectively, all patients were assessed for early and late renal outcome at 12- month and 24-month intervals. Renal outcome was assessed according to serum creatinine level, glomerular filtration rate, active urine sediment, and proteinuria. P <0.05 was considered significant. A total of 68 patients were included, 58 patients (51 females) had SLE and 10 patients (7 females) had AAV completed TPE. All patients had active disease and had AKI. At the first 12 months, 18 patients (17 SLE and 1 AAV) showed complete response and 14 patients had partial response while 22 patients did not show therapeutic benefit. The nonresponders (22 patients) entered the late assessment interval (24 months) without any therapeutic response. Statistically, there was no significant difference between the patient’s response to TPE at the first and second assessment intervals and the baseline serum creatinine level. TPE might be an alternative rescue treatment in lupus nephritis with AKI.

The prevalence of suboptimal Vitamin D levels is higher in patients with chronic kidney disease (CKD) than in the general population. Recent findings suggest that progression of CKD is linked to a suboptimal Vitamin D level. A high percentage of CKD patients have severe Vitamin D deficiency. These patients also have a low level of 25-hydroxy-vitamin D [25(OH)D] and consequently, a reduced ability to form active 1,25-dihydroxyvitamin D. Various factors underlie the low level of 25(OH)D, including a sedentary lifestyle, decreased intake of Vitamin D due to CKD-related dietary restrictions, and decreased synthesis of Vitamin D in skin due to uremia. All these factors may be particularly influential in patients with progressively worsening CKD, including those receiving chronic dialysis. The objective of our study is to determine the prevalence of Vitamin D deficiency in children with CKD stages three to five and those receiving chronic dialysis, to ascertain whether there is a relationship between Vitamin D deficiency and the stage of CKD, and to identify any clinical correlates associated with the Vitamin D status. A single-center, retrospective review was conducted of 46 children (younger than 18 years) with CKD stages 3–5D who attended the renal clinic of the Red Cross Children’s Hospital between October 2013 and November 2014. In total, 73.9% of the study population had suboptimal Vitamin D levels (43.5% and 30.4% had Vitamin D deficiency and insufficiency, respectively). The prevalence of Vitamin D deficiency was significantly higher in older children (≥10 years of age) than in younger children (P = 0.000) but did not significantly differ between males and females (P = 0.693). In total, 12 of 15 black children (80%), 19 of 26 colored children (73.1%), two of four white children (50%), and one Asian child (100%) had suboptimal Vitamin D levels. Neither white nor Asian child had Vitamin D deficiency. In addition, 90% of patients undergoing chronic dialysis, 80% of whom were receiving peritoneal dialysis, had suboptimal Vitamin D levels. Age, weight, height, and the albumin concentration were significantly associated with the Vitamin D level. There was a positive linear relationship between the Vitamin D level and the serum albumin concentration (Spearman’s rho correlation coefficient = 0.397, P = 0.007). In total, 87.5% of patients with nephrotic-range proteinuria had suboptimal Vitamin D levels, and 80% were Vitamin D deficient (P = 0.004). A higher percentage of Vitamin D deficiency/insufficiency cases was documented during the winter (24/34, 70.6%) than during the summer (10/34, 29.4%); however, this difference was not statistically significant (P = 0.685). Sub-optimal Vitamin D is high among children with moderate to severe CKD and significantly higher in those undergoing chronic dialysis. The emerging evidence of the role of Vitamin D in slowing progression of CKD highlights the need for monitoring and correction of Vitamin D levels in predialysis children.

Chronic kidney disease (CKD) is no longer considered just a health burden, but a major health priority owing to its high treatment costs and poor outcome. The lack of community-based screening programs has led to the detection of CKD patients at advanced stages. This study aims to estimate the prevalence of CKD and patterns of known risk factors among the general population (middle-aged and elderly) attending a screening camp in a community-based setting. The study participants constituted a part of the general population of Varanasi (aged ≥45 years) who volunteered in a screening camp that was organized as part of the World Kidney Day Initiative at Opal Hospital. Information on age, sex, height, weight, smoking and drug history, history of diabetes, hypertension, and family history of kidney disease was extensively interrogated, while laboratory investigations such as urinalysis and serum creatinine levels were recorded. More than three-fifths of the participants were middle-aged adults (i.e., 45–64 years) and the remaining 34.8% were elderly population, i.e., ≥65 years. The overall prevalence of CKD in the 198 studied participants was 29.3%. Higher number of participants (40.6%) of elderly population had CKD (P = 0.011). The serum creatinine, albuminuria, and estimated glomerular filtration rate levels were strongly associated with CKD (P <0.05). Our study suggests that elderly individuals are at risk with higher serum creatinine levels and would benefit from early detection of CKD to prevent disease progression and associated morbidity and mortality.

Rheumatoid arthritis (RA) is accompanied by a variety of nephropathies. It is often difficult to distinguish between disease-associated and drug-associated renal diseases. Three hundred and seventy-six RA patients with renal involvement were included in our study; they were subjected to full history and clinical examination, kidney function, 24-h urinary protein, and kidney biopsy. All our patients were on methotrexate, low dose steroids, and nonsteroidal anti-inflammatory drugs, in addition to the previous medications. About 79.3%, 20.7%, 6.9%, and 5.9% of our patients were on leflunomide, hydroxychloroquine, etanercept, and infliximab, respectively. Renal presentation was in the form of nephrotic syndrome (33.5%), persistent subnephrotic proteinuria (12.2%), persistent proteinuria and recurrent hematuria (13.3%), acute nephritis (23.9), recurrent hematuria (7.4%), and creatinine >1.5 mg/dL (10.6%). Renal biopsies were glomerular amyloidosis (28.1%), mesangioproliferative (19.1%), membranous (6.1%), crescent (16.8%), focal segmental glomerulosclerosis (18.6%), and minimal changes (11.7%). There was a statistically significant difference in the incidence of membranous nephritis between patients who took leflunomide, and hydroxychloroquine and those did not. Etanercept in our study seems not to be related to any form of renal involvement, while infliximab is related to focal segmental sclerosis and amyloidosis of tubulointerstitial type. Kidney involvement in RA is not a rare complication. Any type of histopathological changes can be present, with amyloidosis on top of the list. Hydroxychloroquine and leflunomide are accused in membranous nephropathy. Infliximab is associated with focal segmental sclerosis and amyloidosis of tubulointerstial type, and etanercept appear to be safe as regards kidney affection.

Chronic kidney disease (CKD) is still a serious health problem in children with increasing morbidity and affecting children’s quality of life (QoL). The prevalence of children with CKD worldwide is approximately 82 cases/year/1 million children. From the Indonesian Basic Health Survey 2013, the prevalence of patients with CKD aged ≥15 years in Indonesia was 0.2%. To assess the QoL in children with CKD as well as its relationship with duration of diagnosis, severity, and related demographic factors, a cross-sectional analytic study was conducted. Individuals were recruited from July 2016 to May 2017 through consecutive sampling. CKD children aged 2–18 years who treated with conservative therapy and hemodialysis were included. Patients and their parents were asked to fill out the PedsQL™ generic score scale version 4.0 questionnaire. A total of 112 children were recruited, and QoL was assessed from parental reports (54.5%) and children’s reports (56.3%). The school and emotional aspects were the lowest score parameters studied. Factor related to QoL children with CKD were length of diagnosis >60 months (P = 0.004), female (P = 0.019), and middle school (P = 0.003). More than half of the children with CKD have disturbance of QoL in general from parental reports (54.5%) and children’s reports (56.3%). Length of diagnosis >60 months, female, and middle school education were all related to the QoL children with CKD.

Vascular calcification (VC) is a well-known complication in patients with chronic kidney disease (CKD). Keeping in mind, the end goal to assess the genuine effect of mineral bone disease in the pathogenesis of blood vessel calcification during the pre-dialysis course of CKD, we assessed the prevalence and extent of abdominal aortic calcification (AAC) in nondiabetic CKD patients recently starting hemodialysis (HD). Eighty-one patients with end-stage renal disease beginning HD over a one-month period were selected. They underwent a detailed clinical examination and laboratory evaluation, including serum calcium, phosphorus, parathyroid hormone, fibroblast growth factor (FGF-23), and alkaline phosphatase were measured, and spiral computed tomography was performed to evaluate AAC score. AAC was present in 64 patients (79%). There was a significant correlation between the AAC score and age (r = 0.609, P <0.001) and FGF-23 (r = 0.800, P <0.001). This study suggests that the prevalence and extent of AAC are critical in incident HD patients. Serum FGF-23 level is the sole statistically significant correlate of AAC in these patients. 

Significance of paraprotein gap and β2 microglobulins in predialysis Population with multiple myeloma

Saudi Journal of Kidney Diseases and Transplantation 2019 30(4):825-831

Paraprotein gap is sometimes used as a screening tool in some autoimmune diseases, cancers, and screening for latent infections. The increase in the paraprotein gap in these diseases was hypothesized to be the result of increased levels of immunoglobulins, raising the total serum protein without any changes in serum albumin. Our aim was to assess the overall survival using novel chemotherapy, bortezomib compared to traditional ones and to assess if paraprotein gap could be used as a predictor of survival. Finally, we aimed to assess factors that could predict renal response in this population.
