Thesis (M. A. (PHARM.) -- University of Limpopo, 2019 / Introduction Multidisciplinary team (MDT) approach has emerged as one solution to improving chronic kidney disease (CKD) care. The MDT may include a nephrologist, physicians, nurses, dietitians, pharmacists, and social workers, all working together to deliver effective care to patients with CKD. Participation of pharmacists within the renal MDT at Polokwane hospital seems to be limited. The perceived barriers to pharmacists providing renal care services to CKD patients at Polokwane hospital could inform future strategy development, to enhance their participation. The aim of this study was to explore the role of pharmacists in renal care and develop strategies to maximise their participation in the renal multidisciplinary health care team, based on their participation at Polokwane hospital, Limpopo province. Method A qualitative study using semi-structured interviews was conducted with a purposeful sample of 8 members of the renal MDT and 9 pharmacists. The audiotaped interviews were transcribed exactly as said and analysed using thematic content analysis. Results Four themes emerged from the analysis: ‘pharmacist’s current scope of practice within the renal MDT’, ‘potential future roles of pharmacists’, ‘perceived barriers to participation of pharmacists within the renal MDT’ and ‘recommendation/Strategies to incorporate pharmacists into the MDT’. Results have shown that pharmacists have an absent role within the renal MDT. Their role is limited to just dispensing and managing stock, with no role in direct patient care. Both pharmacists and MDT members showed preference to working together during renal care. Pharmacy services suggested include medication reviews, provision of patient education and counselling, patient adherence improvement, dosage workouts, patient monitoring and education on contraindicated drugs and drug interactions. Shortage of staff, pharmacists lack of clinical skills, lack of communication and attitude of pharmacists were perceived as the major barriers to participation of pharmacists within the renal xii MDT. To overcome these barriers, it was recommended that the department of health (DoH) provide more pharmacy staff and educational opportunities in the form of workshops, to equip pharmacists clinically and broaden competency and knowledge on effective communication and coordination. In addition, it was recommended that the clinical curriculum at Universities be revised, to build solid foundation on MDT care and pharmacology and that the MDT programme be standardized through standard treatment guidelines (SOP’s), policies and drawing of job descriptions. Conclusion The role of pharmacists at Polokwane hospital is confined to just stock management and dispensing. There are promising avenues for future development of their role during patient care, which can be achieved by addressing the barriers highlighted Recommendations The expansion of the role of pharmacists within the renal MDT will require improved partnership between health care professionals, resources, legislations and guidance from formal SOPs. Having a national framework for pharmacy practice from Ministry of Health, supported by educational opportunities and a pro-active professional association would be key to incorporating pharmacists within the renal MDT.

A research project submitted in fulfilment of the requirements for the degree of Master of Arts in Psychology through the Faculty of Humanities, University of the Witwatersrand, Johannesburg, 2016 / Background Chronic Kidney Disease (CKD) is a reality faced by many around the world. There has been much physiological study around factors associated with CKD, as well as many studies surrounding the psychosocial impacts of the disease, with relatively less attention given to neuropsychological effects the disease can have on sufferers. This paper investigates the cognitive impacts as well as psychological impacts simultaneously, impacting on sufferers of End Stage Kidney Disease (ESKD). Methods Sixteen medically stable patients aged (M = 40.56, SD = 12.52) years with ESKD, were investigated. Eight of the patients were evaluated before and after six months of successful kidney transplant, using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), which assessed immediate memory, visuospatial / constructional, language, and attention. They were also tested on a brief symptom inventory (BSI 18) to assess depression and anxiety in these patients. A further eight who remained on dialysis, and had not undergone renal transplant were evaluated in the same manner for comparative purposes. Results Between-group comparisons showed a statistically significant improvement in overall cognitive functioning, as well as in the specific cognitive domains of visuospatial / constructional, language and attention for participants who had undergone renal transplant surgery compared to their counterparts who had not. Results also found that there were no statistically significant differences between the levels of anxiety experienced between patients in the two groups. When assessing the differences in cognitive improvement within the transplant patient group before and after transplant, improvement in the delayed memory function of renal transplant patients post-transplant was found. Conclusion These data show improvements in delayed memory function of patients having undergone renal transplant therapy, while also highlighting a continued decline of overall cognitive functioning in patients remaining on hemodialysis therapy. / GR2017

Thesis (M.Sc. (Statistics)) -- University of Limpopo, 2020 / Peritoneal Dialysis (PD) is a process of replacing kidney function which cleans waste from the blood and remove extra fluid from the body. In most cases, the process of PD is slowed down by a peritoneal membrane infection called peritonitis. Despite recent advancements in treatments and prevention, peritonitis still remains the leading complication which results in high morbidity and technique failure among PD patients. Using a prospective peritonitis dataset of 159 kidney patients who were on PD from 2008 to 2015 in Pietersburg Provincial Hospital, the aim of this study was to identify potential social, demographic and biological risk factors that contribute to the first episode of peritonitis. Both semi-parametric (Cox PH) and parametric (Accelerated Failure Time: Weibull, exponential, loglogistic, and gamma) survival models were fitted to the peritonitis dataset. Akaike Information Criterion (AIC) was applied to select models which best fit to the peritonitis data. Accordingly, log-logistic Accelerated Failure Time (AFT) model was found to be a working model that best fit to the data. A total of 96 (60.38%) peritonitis cases were recorded over the follow-up period with majority of peritonitis infection coming from females (65.4%) and rural dwellers (65.7%) with (62.6%) of black Africans showing higher risk of developing peritonitis. The multivariate log-logistic AFT model revealed that availability of water (p-value=0.018), electricity (p-value=0.018), dwelling (p-value=0.008), haemoglobin status (p-value=0.002) and duration on PD (p-value=0.001) are significant risk factors for the development of peritonitis. Therefore, patients with no water and electricity, coming from rural background with low level of haemoglobin and shorter duration on PD are associii ated with high risk or hazard of developing peritonitis for the first time.

Patients were selected for the study on the basis of 1: A diagnosis of systemic Lupus Erythematosus according to the 1982 revised American Rheumatology Association criteria47 and 2: An adequate biopsy defined as containing at least six glomeruli. Patients were biopsied at Groote Schuur Hospital during the period 1978 to 1988 and the indications for renal biopsy were clinical based on laboratory results of renal function. Patients were followed between 1 and 120 months with a mean observation period of 34 months. The clinical records were scrutinised and the following pa·rameters were noted at the time of biopsy: age, sex, race, time from diagnosis to biopsy, serum urea, creatinine, creatinine clearence and urinary 24 hour protein. Using the latest serum urea, creatinine, creatinine clearence and / or 24 hour urinary protein where available, outcome was graded as: 1: An improvement in renal function 2: A stable renal function 3: Deterioration in renal function 4: Patient on dialysis 5: Death due to disease.

The purpose of this study was to identify determinants of compliance behavior. Since compliance among dialysis patients increases survival rate, it is important for social workers to identify patients who are at risk of noncompliance.

Thesis (M. Tech. (Biomedical technology)) - Central University of technology, Free State, 2013 / INTRODUCTION: The renal effects of Tenofovir Disoproxil Fumarate (TDF) and antiretroviral treatment (ART) outcomes remain under-reported in African settings. The study sought to assess immunological outcomes and to compare renal function outcomes between patients exposed to TDF and unexposed patient group. METHODS: Phase 1 of the study was a retrospective case control analysis of serum creatinine data for 312 ART naïve adult patients exposed to TDF and 173 unexposed patients enrolled on ART between Dec 2006 and Jan 2011 at Roma Health Service Area in Lesotho. Sub-optimal renal function outcomes were serum creatinine clearance values <50 ml/min calculated using the Cockcroft-Gault equation. Phase 2 was based on re-sampling of the study population and analysis of CD4 counts of 516 adult naïve HIV-positive patients. Univariate logistic regression (p<0.1) and multivariate analyses (p<0.05) were performed using STATA® version 11 software. RESULTS: Overall, 153 (31.5%) patients had moderate baseline (30-60 ml/min) renal insufficiency. Renal function improved by +2 ml/min at 24 months. Almost 18% (n=312) of the patients on TDF were erroneously put on TDF. The use of TDF was a marginally significant factor (p=0.054) associated with CrCl<50 ml/min outcomes in univariate analysis but was insignificant (p=0.122) in multivariate analysis. Female gender (p=0.016), high blood pressure (p=0.009), ages over 60 (p=0.004), and underweight (p<0.001) were significantly associated with CrCl<50 ml/min outcomes. The proportion of patients who developed immunological failure in this study was low (6.8%, n=516). The mean CD4 count increased significantly after treatment (p<0.001). Baseline CD4 count below 50 cells/mm3 (p=0.049) and male gender (p=0.005) were significantly associated with sub-optimal immunological outcomes. CONCLUSIONS: TDF is a weak contributing factor associated with renal impairment outcomes compared to other variables such as hypertension, older age, underweight and female gender. More research on long term effects of TDF is recommended. Baseline renal function screening should be improved to minimise leakages of patients contraindicated of TDF. Although the patients’ immunological status generally improved, males and patients with low baseline CD4 counts should be monitored closely while on ART.

Text in Afrikaans / Summaries in Afrikaans and English / Psigonefrologie behels die studie von psigologiese faktore wat 'n rot speel by eindstadiumnierversaking. Nierversaking word beskou as 'n lewensbedreigende siekte, wat die lewensverwogting von die pasient verkort indien hy nie behandeling ontvang nie. Nierversaking kan ingedeet word in drie stadiums: Die pre-dialise, diatise, en oorplantingstadiums. Die onderskeibaorheid von hierdie stadiums is die gevotg von verski lie in mediese behandelingsmetodes. Nie een hiervon bring genesing nie, maar vertig simptome van die uremiese sindroom, verleng die tewensverwagting von die pasient, en is veronderstel om sy lewenskwaliteit te verbeter. DepresS,ie en angs, is algemene simptome wat by nierpasiente voorkom. Die redes hiervoor, is die pasient se psigologiese reaksie teenoor nierversaking, dialise, en/of 'n oorplanting. Verder moet hy ook die newe-effekte van die mediese behandeling trotseer. Aanpassings moet ook gemaak word in terme von beroep~ en sosiate funksionering. Nie net het eindstodiumnierversaking 'n psigososiate impok op die nierposient nie, maar word die gesonde moat ook daardeur be"invtoed. Daarom ervoar meeste egpore gesamentlik die impok von nierversaking op hulle huwelik- en gesinslewe. Vir optimale oanpassing by nierversaking moet egpore sekere oanpassingstoke bemeester, soos om nierversoking as 'n gedeetde probteem te hanteer, oan te pas by die rot von pasient en versorger. die verskillende behoeftes oan nobyheid en afstand tussen pasient en versorger, en die verwisseting in beroepsrolle hanteer, asook effektiewe kommunikasie met mekoar en die mediese span doarstel, en mekaor deurlopend instrumenteel en emosioneel ondersteun ten einde die huweliksverbintenis in stand te hou. Die resultate von hierdie ondersoek dui doarop dat huweliksverondertikes, soos 'n afnome in ontsponningsaktiwiteite en seksuatiteit, en gelykmakende rolle 'n belangrike rot speel om oanpassing by nierversaking te vergemaklik. Daarmee soam is gevind dat godsdiens 'n belangrike oanpossende funksie vir egpore het. Deurgoans speel'n ondersteuningsisteem, wat uit famitie en vriende, onder nierpasiente, die mediese span en 'n sielkundige bestoan 'n vernome rol om die egpoar met oanpassing te help. Uiteindelik blyk dit moonttik te wees vir egpare om hulle huwetiksverhouding in stand te hou, of setfs konstruktief te herstruktureer, asook groter huwelikstevredenheid te ervoar, ondanks die bedreiging von eindstadiumnierversaking. Meeste egpore ervoar die moeilike tydperk dan ook met 'n verdieping in hulle huwelik- en geloofslewe. / Psychonephrology is the study of psychological factors which are evident in end-stage renal disease (ESRD). ESRD is regarded as a life-threatening disease, which shortens the life-expectancy of a patient if he does not receive treatment. ESRD can be divided into three stages: the pre-dialysis, dialysis and transplant stages. These stages are signified by differences in medical treatment methods. None of these leads to a cure but all alle.viate symptoms of the uremic syndrome, increase the life-expectancy of the patient and are supposed to improve his quality of life. Depression and anxiety are general symptoms found in end-stage renal patients. The reasons for this are the patient's psychological reaction to renal disease, dialysis and/or transplant. Patients must also endure the side effects of medical treatment. Adjustment in vocational and social functioning is also evident. ESRD not only has a psycho social impact on the patient but also affects the healthy spouse. This is why most married couples together experience the impact of ESRD in their marital and family life. For optimal adjustment to ESRD couples need to master certain adaptational tasks, such as treating ESRD as a shared problem, adopt the roles of patient and caregiver, manage the various needs of closeness and distance between patient and caregiver and change of career roles, as well as effectively communicating with each other and the medical team, and instrumentally and emotionally support eac~ other in order to maintain the marital bonds. The results of this investigation show that marital variables, such as a decrease in recreation and sexuality and role equality, are important to ease the adjustment to ESRD. It was also found that religion has an important adaptational function for the married couples. A support system of family, friends, other renal patients, the medical team and a psychologist are also important to aid the couples' adjustment. Lastly it should be possible for renal couples to maintain, or even to positively reconstruct their marital relationship, and to experience marital satisfaction in the face of the threat of ESRD. Apparently most couples experience this ordeal as a time of intensification of their married and spiritual life. / Psychology / D.Litt. et Phil. (Psychology)

Conclusions. The growing epidemic of type 2 diabetes and its cardiorenal complications place a major burden on our health care system. Diabetic kidney disease is of particular importance in Asian populations including Chinese. In this series of studies, using a large prospective cohort established since 1995, I confirmed the powerful predictive value of albuminuria on cardio-renal complications. Inhibition of the RAAS interacted with both modifiable and genetic factors, notably the ACE I/D polymorphism, on the development of cardio-renal complications. In addition, it was found that CKD predicts CVD independent of albuminuria. Based on two prospective studies, I confirmed the effectiveness of global risk-factor control using structured care protocol to prevent these devastating complications. (Abstract shortened by UMI.) / I then examined the possible independent and interactive effects of CKD and albuminuria on cardio-renal outcomes in the original cohort of 5,004 patients. Glomerular filtration rate was estimated (eGFR) by the Modification of Diet in Renal Disease equation. The frequency of CKD as defined by eGFR &lt;60ml/min/1.73m 2 was 15.8% in the cohort at baseline, when 6% of patients had serum creatinine &ge;150mumol/L. / In collaboration with colleagues, I have conducted a series of studies to examine the prognostic factors for cardio-renal complications in Chinese type 2 diabetic patients. The modulating effects of RAAS inhibition and the effectiveness of rnuitidisciplinary care to prevent ESRD are also examined. / Research Hypotheses. (1) Albuminuria is a prognostic factor on cardio-renal outcomes in type 2 diabetes patients; (2) Chronic Kidney Disease is associated with other metabolic risk factors and phenotypes and is a prognostic factor on cardio-renal outcomes in type 2 diabetes patients; (3) Angiotensin-converting-enzyme insertion/deletion polymorphism is a prognostic factor on cardio-renal outcomes in type 2 diabetes patients, and has an effect on treatment responses with RAAS blockage with ACE inhibitors; (4) Structured care models by risk stratification using various prognostic factors and adherence to care protocol can improve cardio-renal outcome in type 2 diabetes patients. / Results. In a prospective cohort of 5,004 patients, I examined the effect of albuminuria and ACE inhibition on survival and cardio-renal outcomes in 3,773 patients who had been observed for at least 6 months with a mean follow up period of 35.8 months. / Taken together, measurement of serum creatinine alone without GFR estimation may underestimate the frequency of CKD in Chinese type 2 diabetic patients. Estimated GFR was inversely associated wit-29h an increasing frequency of micro- and macrovascular complications cross-sectionally and an increased risk of all-cause mortality prospectively, independent of albuminuria and metabolic control. / So Wing Yee. / Source: Dissertation Abstracts International, Volume: 70-06, Section: B, page: 3422. / Thesis (M.D.)--Chinese University of Hong Kong, 2008. / Includes bibliographical references (leaves 203-243). / Electronic reproduction.

Background. Diabetes mellitus is a complex metabolic disorder characterized by clustering of multiple cardiovascular risk factors. Diabetic albuminuria is associated with increased prevalence of both micro-vascular and macro-vascular complications. This thesis examined vascular function (Flow-mediated dilatation, FMD) in type 2 diabetic patients with particular emphasis on its relationships with nephropathy. Independent predictors for FMD in Chinese population using data from both diabetic and non-diabetic subjects as well as the predictive value of FMD on clinical endpoints and death in type 2 diabetic patients with nephropathy were examined. / Conclusions. In Chinese subjects with or without type 2 diabetes, hyperglycaemia, hypertriglyceridemia, smoking and albuminuria were independent predictors for FMD. Type 2 diabetic subjects with overt nephropathy had impaired endothelium-dependent and endothelium-independent dilatation, suggesting vascular dysfunction beyond the endothelium. In agreement with studies from Caucasians, smoking was the most important determinant for vascular dysfunction in Chinese type 2 diabetic patients with overt nephropathy. Furthermore, FMD was predictive of new onset of cardiovascular events and related death in Chinese type 2 diabetic patients with overt nephropathy. / In diabetic patients with overt nephropathy, smoking (current and ex-smokers), waist hip ratio (WHR) and serum creatinine were independent predictors for impaired FMD. The latter was predictive of advancement of IMT and was an independent predictor for new onset of combined cardiovascular diseases and related death after a follow up period of 42 months (log rank test=6.04, p=0.014 using Cox regression analysis) after controlling for all confounding factors. In addition, fasting total cholesterol and plasma glucose were predictive for all-cause mortality while serum creatinine predicted new onset of renal endpoint. In a subgroup analysis in diabetic patients with overt nephropathy, smokers who developed CVD or ESRD had greater diminution of FMD than those who did not develop clinical endpoints. / Methods and results. FMD was assessed using high-resolution ultrasound scan. In the cross-sectional study, the sample population was divided into four groups according to the presence or absence of type 2 diabetes and level of albuminuria. They included the non-diabetic group (N=52), diabetic group with normoalbuminuria (N=18), diabetic group with microalbuminuria (N=18) and diabetic group with overt nephropathy defined as macroalbuminuria and renal insufficiency (N=22). Compared to non-diabetic subjects, type 2 diabetic subjects with nephropathy had impaired FMD (4.54% +/- 2.25 vs. 2.50% +/- 2.31, p&lt;0.05) and impaired GTN-dependent dilatation (GTND) (14.30% +/- 3.77 vs. 12.70% +/- 4.70, p&lt;0.05). They also had reduced endothelium-dependent dilatation to endothelium-independent dilatation ratio when compared to non-diabetic subjects (0.19 +/- 0.17 vs. 0.32 +/- 0.15, p&lt;0.05). These findings suggest that the impaired vascular dilatation was due to dysfunction of both endothelium and vascular smooth muscle cells. In the entire cohort, fasting plasma glucose, fasting triglyceride, smoking and albuminuria were independent predictors for FMD. / Lai Wai Keung Christopher. / "February 2006." / Source: Dissertation Abstracts International, Volume: 67-11, Section: B, page: 6298. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2006. / Includes bibliographical references (p. 202-252). / Electronic reproduction.
