RESUMEN
AIM: This cross-sectional survey aimed to determine the prevalence of Interventional Nephrology (IN) practice amongst nephrologists in the Asia-Pacific Region (APR), specifically related to dialysis access (DA). METHODS: The Association of VA and intervenTionAl Renal physicians (AVATAR) Foundation from India conducted a multinational online survey amongst nephrologists from the Asia-Pacific to determine the practice of IN in the planning, creation, and management of dialysis access. The treatment modalities, manpower and equipment availability, monthly cost of treatment, specifics of dialysis access interventions, and challenges in the training and practice of IN by nephrologists were included in the survey. RESULTS: Twenty-one countries from the APR participated in the survey. Nephrologists from 18 (85.7%) countries reported performing at least one of the basic dialysis access-related IN procedures, primarily the placement of non-tunnelled central catheters (n-TCC; 71.5%). Only 10 countries (47.6%) reported having an average of <4% of nephrologists performing any of the advanced IN access procedures, the most common being the placement of a peritoneal dialysis (PD) catheter (20%). Lack of formal training (57.14%), time (42.8%), incentive (38%), institutional support (38%), medico-legal protection (28.6%), and prohibitive cost (23.8%) were the main challenges to practice IN. The primary obstacles to implementing the IN training were a lack of funding and skilled personnel. CONCLUSION: The practice of dialysis access-related IN in APR is inadequate, mostly due to a lack of training, backup support, and economic constraints, whereas training in access-related IN is constrained by a lack of a skilled workforce and finances.

INTRODUCTION: This review article reports clinical outcomes and performance indicators of patients with kidney failure (KF) and acute kidney injuries (AKI) in Association of South East Asian Nations (ASEAN) countries. METHODOLOGY: Association of South East Asian Nations data, segregated by income status, from national registries and literature were collated, compared and benchmarked against international references. RESULTS: The national incidence and prevalence of treated KF ranged from 172 to 479 per million population (pmp) and 36-2255 pmp, respectively. Brunei (79%), Malaysia (66%) and Singapore (66%) had world-leading proportions of diabetes-related KF. Hemodialysis (HD), Peritoneal Dialysis (PD) and transplant accounted for 68-100%, 0-27% and 0-18% of all KF replacement therapy, respectively. Transplant patient survival was superior with 90%-93% at 5 years and 71%-90% at 10 years, compared to PD (44%-54%) and HD (53-64%) at 5 years. Higher-income countries were able to achieve good anemia control, HD and PD adequacy targets, while usage of arteriovenous fistula in HD varied from 70% to 85%. Acute Kidney Injury rates ranged from 24.2% to 49.2% of high-dependency admissions. Lower incidences of PD peritonitis and HD catheter-related Bloodstream Infections; and PD-favouring quality-of-life were evident in higher-income countries. CONCLUSION: Association of South East Asian Nations has a challenging burden of kidney disease, with extremely high incidence, prevalence, DM-related KF and AKI rates. The magnitude of the prevailing problem calls for the creation of a regional society under the auspices of ASEAN with a shared perspective of universal, equitable and charitable access to quality renal care; consistent with the founding premises and healthcare initiatives of ASEAN.

Increasing global precipitation has been associated with a warming climate resulting from a strengthening of the hydrological cycle. This increase, however, is not spatially uniform. Observations and models have found that changes in rainfall show patterns characterized as 'wet-gets-wetter' and 'warmer-gets-wetter'. These changes in precipitation are largely located in the tropics and hence are probably associated with convection. However, the underlying physical processes for the observed changes are not entirely clear. Here we show from observations that most of the regional increase in tropical precipitation is associated with changes in the frequency of organized deep convection. By assessing the contributions of various convective regimes to precipitation, we find that the spatial patterns of change in the frequency of organized deep convection are strongly correlated with observed change in rainfall, both positive and negative (correlation of 0.69), and can explain most of the patterns of increase in rainfall. In contrast, changes in less organized forms of deep convection or changes in precipitation within organized deep convection contribute less to changes in precipitation. Our results identify organized deep convection as the link between changes in rainfall and in the dynamics of the tropical atmosphere, thus providing a framework for obtaining a better understanding of changes in rainfall. Given the lack of a distinction between the different degrees of organization of convection in climate models, our results highlight an area of priority for future climate model development in order to achieve accurate rainfall projections in a warming climate.

OBJECTIVE: A limited study was found in regards to knowledge, attitudes, and practices (KAP) of traditional and complementary/alternative medicines (TCAM) amongst end-stage renal disease (ESRD) in South East Asian region including Brunei Darussalam. This study explored TCAM use amongst ESRD patients in Brunei Darussalam. METHODS: This was a cross-sectional study in a local Dialysis Centre using a bilingual self-structured questionnaire. Recruitment was done using systematic random sampling with certain inclusion criteria. All collected data were entered into Microsoft Excel 2016, and inferential statistics were carried out using R studio version 1.1.383. RESULTS: About 40.2% were TCAM users, and this was not predictable by any sociodemographic background. Nevertheless, compliance with conventional medicine (CM) was very high (94.1%). Users had a more positive disease perception, which was not affected by length on dialysis treatment or the presence of comorbidities. TCAM was perceived to be less effective and unsafe compared to CM, and patients agreed that its use should be monitored and notified. Health supplement (70.7%) was mainly used to improve general wellness (48.5%) or to relieve fatigue (42.4%), and most practices were influenced by family (43.9%). Only a minority of users (19.5%) reported side effects as majority (80.5%) consumed TCAM and CM separately. CONCLUSIONS: High TCAM practice showed that there are still needs that are not fulfilled. The health care professionals should always remain vigilant of its use and be attentive to attend to patients' needs.

Asia is the largest and most populated continent in the world, with a high burden of kidney failure. In this Policy Forum article, we explore dialysis care and dialysis funding in 17 countries in Asia, describing conditions in both developed and developing nations across the region. In 13 of the 17 countries surveyed, diabetes is the most common cause of kidney failure. Due to great variation in gross domestic product per capita across Asian countries, disparities in the provision of kidney replacement therapy (KRT) exist both within and between countries. A number of Asian nations have satisfactory access to KRT and have comprehensive KRT registries to help inform practices, but some do not, particularly among low- and low-to-middle-income countries. Given these differences, we describe the economic status, burden of kidney failure, and cost of KRT across the different modalities to both governments and patients and how changes in health policy over time affect outcomes. Emerging trends suggest that more affluent nations and those with universal health care or access to insurance have much higher prevalent dialysis and transplantation rates, while in less affluent nations, dialysis access may be limited and when available, provided less frequently than optimal. These trends are also reflected by an association between nephrologist prevalence and individual nations' incomes and a disparity in the number of nephrologists per million population and per thousand KRT patients.

BACKGROUND: Acute Kidney Injury (AKI) is common in elderly people (EP). There is paucity of data on predictor of mortality in EP with AKI. OBJECTIVE: This study was done to know more about factors associated with inpatient mortality in EP with AKI. METHODS: We retrospectively reviewed medical records of patients aged 65 years or above hospitalized with a diagnosis of AKI at Aga Khan University Hospital, Karachi, between January 2005 and December 2010. Binary logistic regression models were constructed to identify factors associated with mortality in EP with AKI. RESULTS: 431 patients had AKI, with 341 (79.1%) having stage I AKI, 56 (13%) having stage II AKI, and 34 (7.9%) having stage III AKI. Out of 431 patients, 142 (32.9%) died. Mortality increased with increasing severity of AKI. Mortality was 50% (17/34) in AKI stage III, 44.6% (25/56) in AKI stage II, and 29.3% (100/341) in AKI stage I. Factors associated with increased inpatients mortality were presence of stage III AKI (OR: 3.20, P = 0.04, 95% CI: 1.05-9.72), presence of oliguria (OR: 3.42, P = 0.006, 95% CI: 1.42-8.22), and need for vasopressors (OR: 6.90, P < 0.001, 95% CI: 2.42-19.65). Median bicarbonate 18 versus 17 between those who survived and those who died was associated with less mortality (OR: 0.94, P = 0.02, 95% CI: 0.89-0.99). History of hypertension (OR: 0.49, P = 0.03, 95% CI: 0.25-0.95) and high admission creatinine (OR: 0.68, P = 0.01, 95% CI: 0.50-0.91) were also associated with less mortality. CONCLUSION: Mortality in EP increases with increasing severity of AKI. Presence of stage III AKI, oliguria, and hemodynamic instability needing vasopressor are associated with increased mortality. Increased median bicarbonate, presence of hypertension, and high admission creatinine were various factors associated with decreased inpatient mortality. Increasing age and need for dialysis did not increase mortality in elderly population.

BACKGROUND: Effusion is common in dialysis patients. The most common causes include fluid overload due to renal failure and nonrenal causes like congestive heart failure and infection. We here report a case of left side transudative effusion due to brachiocephalic venous stenosis. METHODS: A 34-year-old female who had chronic kidney disease V during transplant work-up was found to be having left arm swelling and left transudative effusion. Work-up for transudative effusion did not show any cardiac cause or liver problem. Her dialysis duration was optimized from 2 times a week to 3 times a week for 4 hr and her dry weight was adjusted. Despite adequate dialysis for 1 month, effusion on the left side persisted. She had a previous venoplasty for a stenosis in brachiocephalic vein but restenosis occurred again. RESULTS: Brachiocephalic vein stenting was performed which successfully lead to resolution of left arm swelling and left effusion. She was later on successfully transplanted. CONCLUSIONS: Brachiocephalic stenosis can cause ipsilateral transudative effusion. Venoplasty and stenting of the brachiocephalic vein lead to complete resolution of effusion.

Watermelon Stomach or gastric antral vascular ectasia (GAVE) is a rare cause of chronic gastrointestinal blood loss. It has been commonly associated with autoimmune connective tissue and chronic liver disease. It is characterized by endoscopic appearances of erythematous patches secondary to dilated vessels that can be diffusely located or in linear stripes. Histology is characterized by dilated mucosa capillaries with fibrin thrombi and fibromuscular hyperplasia. Unless recognized, the endoscopic findings can be misdiagnosed as severe gastritis. GAVE can be treated using various modalities with variable success. We report four cases of GAVE as the cause of chronic gastrointestinal blood loss in patients with end stage renal disease. A literature review of this rare and interesting entity is presented.

BACKGROUND AND AIM: Brunei Darussalam is a small South East Asian country with a high prevalence and incidence of end stage kidney disease (ESRD). This study aims to compare key performance indicators recorded in the Brunei Dialysis and Transplant Registry and department records against international practice. Registries from the USA (USRDS), UK (UK Renal Registry), Australasia (ANZDATA), Europe (ERA-EDTA Registry) and Malaysia (MDTR) were used for comparisons. METHODS AND RESULTS: Haemodialysis (83%) and renal transplantation (6%) were the most and least favoured modality of renal replacement therapy in Brunei. Diabetes mellitus as a cause of ESRD (57%) was high in Brunei but on par with other South East Asian countries. Dialysis death rates (11%) and living-related transplant survival rates (5 year graft and patient survival 91% and 96% respectively) were favourable compared with other registries. Anaemia and mineral bone disease management were similar to Malaysia but slightly inferior to the others, but generally in keeping with KDOQI and KDIGO targets. Haemodialysis adequacy (48% achieving urea reduction ratio of >65%) was relatively poorer due to poor dialysis flow rates and low fistula usage (71%). Peritoneal dialysis peritonitis (24.5 patient-month/episode) and adequacy (78% achieving kt/v of 1.7) were in keeping with ISPD targets and international registries' results. CONCLUSION: Brunei has achieved reasonable and commendable standards in many areas pertaining to the renal services. This report has identified several key areas for developments but this is to be expected for a service making its first foray into international benchmarked practice.

There is shortage of organs, including kidneys, worldwide. Along with deceased kidney transplantation, there is a significant rise in live kidney donation. The prevalence of prediabetes (PD), including impaired fasting glucose and impaired glucose tolerance, is on the rise across the globe. Transplant teams frequently come across prediabetic kidney donors for evaluation. Prediabetics are at risk of diabetes, chronic kidney disease, cardiovascular events, stroke, neuropathy, retinopathy, dementia, depression and nonalcoholic liver disease along with increased risk of all-cause mortality. Unfortunately, most of the studies done in prediabetic kidney donors are retrospective in nature and have a short follow up period. There is lack of prospective long-term studies to know about the real risk of complications after donation. Furthermore, there are variations in recommendations from various guidelines across the globe for donations in prediabetics, leading to more confusion among clinicians. This increases the responsibility of transplant teams to take appropriate decisions in the best interest of both donors and recipients. This review focuses on pathophysiological changes of PD in kidneys, potential complications of PD, other risk factors for development of type 2 diabetes, a review of guidelines for kidney donation, the potential role of diabetes risk score and calculator in kidney donors and the way forward for the evaluation and selection of prediabetic kidney donors.
RESUMEN
Objective: Coronavirus disease (COVID-19) vaccinations have been shown to prevent infection with efficacies ranging from 50% to 95%. This study assesses the impact of vaccination on the clinical severity of COVID-19 during the second wave in Brunei Darussalam in 2021, which was due to the Delta variant. Methods: Patients included in this study were randomly selected from those who were admitted with COVID-19 to the National Isolation Centre between 7 August and 6 October 2021. Cases were categorized as asymptomatic, mild (symptomatic without pneumonia), moderate (pneumonia), severe (needing supplemental oxygen therapy) or critical (needing mechanical ventilation) but for statistical analysis purposes were dichotomized into asymptomatic/mild or moderate/severe/critical cases. Univariate and multivariable analyses were conducted to identify risk factors associated with moderate/severe/critical disease. Propensity score-matched analysis was also performed to evaluate the impact of vaccination on disease severity. Results: The study cohort of 788 cases (mean age: 42.1 ± 14.6 years; 400 males) comprised 471 (59.8%) asymptomatic/mild and 317 (40.2%) moderate/severe/critical cases. Multivariable logistic regression analysis showed older age group (≥ 45 years), diabetes mellitus, overweight/obesity and vaccination status to be associated with increased severity of disease. In propensity score-matched analysis, the relative risk of developing moderate/severe/critical COVID-19 for fully vaccinated (two doses) and partially vaccinated (one dose) cases was 0.33 (95% confidence interval [CI]: 0.16-0.69) and 0.62 (95% CI: 0.46-0.82), respectively, compared with a control group of non-vaccinated cases. The corresponding relative risk reduction (RRR) values were 66.5% and 38.4%, respectively. Vaccination was also protective against moderate/severe/critical disease in a subgroup of overweight/obese patients (RRR: 37.2%, P = 0.007). Discussion: Among those who contracted COVID-19, older age, having diabetes, being overweight/obese and being unvaccinated were significant risk factors for moderate/severe/critical disease. Vaccination, even partial, was protective against moderate/severe/critical disease.

Deceased donor kidney transplantation (DDKT) is common in high income Western countries with high transplantation rates. However, the utilization of deceased organs is suboptimal in Asia, due to a multitude of factors. Coherent policies are integral to the development of DDKT programs and deterrence of commercialization, but most are still at an infancy and formative stage in Asia. This review article identifies the glass ceiling effects of social, cultural, religious, political, and technical factors hampering the progress of DDKT in Asia. Additionally, it reviews the history of policy development in different countries and describes their idiosyncratic barriers and challenges. Lastly, it discusses innovative policy measures that can be undertaken to proliferate DDKT practice and curtail commercialization. The long-term ideal is to achieve regional equity and self-sufficiency, through a shared ethos of social and ethical responsibility that transcends and resonates with the different segments of the Asian community.
RESUMEN
BACKGROUND: This paper presents the level of colorectal cancer awareness among multi-ethnic rural population in Malaysia. METHODS: A rural-based cross sectional survey was carried out in Perak state in Peninsular Malaysia in March 2011. The survey recruited a population-representative sample using multistage sampling. Altogether 2379 participants were included in this study. Validated bowel/colorectal cancer awareness measure questionnaire was used to assess the level of colorectal cancer awareness among study population. Analysis of variance (ANOVA) was done to identify socio-demographic variance of knowledge score on warning signs and risk factors of colorectal cancer. RESULTS: Among respondents, 38% and 32% had zero knowledge score for warning signs and risk factors respectively. Mean knowledge score for warning signs and risk factors were 2.89 (SD 2.96) and 3.49 (SD 3.17) respectively. There was a significant positive correlation between the knowledge score of warning signs and level of confidence in detecting a warning sign. Socio-demographic characteristics and having cancer in family and friends play important role in level of awareness. CONCLUSIONS: Level of awareness on colorectal cancer warning signs and risk factors in the rural population of Malaysia is very low. Therefore, it warrants an extensive health education campaign on colorectal cancer awareness as it is one of the commonest cancer in Malaysia. Health education campaign is urgently needed because respondents would seek medical attention sooner if they are aware of this problem.

AIM: Gastrointestinal (GI) symptoms are reported to be common among patients with chronic disorders including end-stage renal disease (ESRD). This questionnaire study assessed the prevalence of GI symptoms among patients undergoing hemodialysis (HD) and to correlate with the presence of diabetes mellitus and psychosomatic symptoms in Asian patients with ESRD. METHODS: A total of 123 patients (male 47.2%) participated in this study. GI symptoms (upper GI: anorexia, nausea, vomiting, odynophagia, dysphagia, early satiety, heartburn, dyspepsia and lower GI: abdominal bloating, non-epigastrium abdominal pain, bowel habit and bleeding per rectum) and psychosomatic symptoms (anxiety, backache, depression, headache and insomnia) in the previous 12 months were enquired and compared with age and gender matched controls (n = 197). RESULTS: The mean age of patients was 51.8 ± 12.9 years with mean duration of HD of 28 ± 38.2 months. Overall, 70.7% of ESRD patients had experienced any GI symptoms; upper GI, 65% and lower GI, 34.1%, significantly more than controls (P < 0.05). ESRD patients had more anorexia, nausea, vomiting, dyspepsia, irregular bowel habit and bleeding per rectum (all P < 0.05). Overlap of upper and lower GI symptoms was reported by 34.1%, significantly higher than control (14.2%, P < 0.05). ESRD patients also experienced significantly more anxiety, depressive symptoms and insomnia (all P < 0.05). Among the patients with ESRD, the presence of any psychosomatic symptoms correlated significantly with the presence of any upper or lower GI symptoms and overlapping of GI symptoms. Such correlations were not seen with diabetes mellitus. CONCLUSION: Gastrointestinal and psychosomatic symptoms are common among our Asian patients with ESRD undergoing regular HD. The presence of underlying psychosomatic symptoms but not diabetes mellitus correlated significantly with the presence of GI symptoms.

The Brunei Dialysis and Transplant Registry (BDTR) was established in 2011 to collect data from patients undergoing renal replacement therapy (RRT) in Brunei Darussalam. The chief aims of the registry are to obtain general demographic data for RRT patients and to determine disease burden attributable to End Stage Renal Disease (ESRD). The registry population comprises of all ESRD patients treated in Brunei Darussalam. Data domains include general demographic data, medical history, ESRD etiological causes, laboratory investigations, dialysis treatment and outcomes. There were 545 prevalent RRT patients in Brunei at the end of 2011. The incidence and prevalence of ESRD were 265 and 1250 per million population. Hemodialysis (HD), Peritoneal Dialysis (PD) and Transplant comprised of 83%, 11% and 6% of the RRT population, respectively. Diabetes mellitus accounted for 57% of all new incident cases. The mean serum hemoglobin, phosphate, calcium and iPTH were 11.0 ± 1.6 g/dL, 1.9 ± 0.5 mmol/L, 2.3 ± 0.2 mmol/L and 202.5 ± 323.4 ng/mL. Dialysis adequacy for HD and PD were 65.1 (urea reduction ratio) and 2.0 ± 0.3 (Kt/v). 71 % of all prevalent HD had functioning AV fistulae and the peritonitis incidence was one in 24.5 patient-month/episode. The first BDTR has identified some deficiencies in the renal services in Brunei. However, it signals an important milestone for the establishment of benchmarked renal practice in the country. We hoped to maintain and improve our registry for years to come and will strive to align our standards to acceptable international practice.

INTRODUCTION: Acute kidney injury (AKI) in coronavirus disease 2019 (COVID-19) patients affects their health outcomes. Incidence and outcomes varied in the literature, particularly with different population and epidemiological demographics. Data remain scarce in the Southeast Asia region. We report the incidence, outcomes, pattern, types of AKI, and factors that influence AKI patient outcomes in Brunei Darussalam. METHODS: All patients (N = 930) with COVID-19 who were admitted to the National Isolation Center (between 7th August 2021 and 30thSeptember 2021) were included in the study. The confirmation of AKI was based on the KDIGO (Kidney Disease Improving Global Outcomes) criteria. RESULTS: The mean age of the patients was 41.9 ± 14.4 years with diabetes mellitus (DM), hypertension (HT), and chronic kidney disease (CKD) accounting for 11.7%, 29.1%, and 4.8% of comorbidities, respectively. Overall, 109 (11.7%) had AKI (KDIGO Stage 1 [67.9%], 2 [13.8%], and 3 [18.3%]), while 75.2% of the cases occurred pre-admission and 26.6% were cases of acute exacerbation of CKD. Univariate analysis identified age (odd ratio [OR] 1.06), male gender (OR 1.63), local nationality (OR 8.03), DM (OR 4.44), HT (OR 5.29), vascular disease (OR 6.08), presence of gastrointestinal symptoms (OR 2.08), antibiotic (OR 3.70) and nephrotoxins exposures (OR 8.57) as significant variables. Multivariate analysis showed age (adjusted OR [AOR] 1.04), male gender (AOR 1.67), gastrointestinal symptoms (AOR 1.61), antibiotic (AOR 2.34), and nephrotoxins exposure (AOR 4.73) as significant. CONCLUSIONS: Our study showed that one in nine patients with COVID-19 developed AKI with almost a third having stages 2 and 3 AKI. Older age, male gender, presence of GI symptoms, and antibiotic and nephrotoxin exposures were significant predictors of AKI. Patients with these factors should be prioritized for admission and treatment. Even though manifestations are generally now less severe, findings from this study can guide the management of COVID-19 as the disease enters the endemic stage. Furthermore, lessons learned from the COVID-19 pandemic will provide useful information and knowledge for future viral outbreaks or pandemics.
RESUMEN
Mammalian target of rapamycin inhibitors (mTOR-I) lacks nephrotoxicity, has antineoplastic effects, and reduces viral infections in kidney transplant recipients. Earlier studies reported a significant incidence of wound healing complications and lymphocele. This resulted in the uncomfortable willingness of transplant clinicians to use these agents in the immediate posttransplant period. As evidence and experience evolved over time, much useful information became available about the optimal use of these agents. Understandably, mTOR-I effects wound healing through their antiproliferative properties. However, there are a lot of other immunological and nonimmunological factors which can also contribute to wound healing complications. These risk factors include obesity, uremia, increasing age, diabetes, smoking, alcoholism, and protein-energy malnutrition. Except for age, the rest of all these risk factors are modifiable. At the same time, mycophenolic acid derivatives, steroids, and antithymocyte globulin (ATG) have also been implicated in wound healing complications. A lot has been learnt about the optimal dose of mTOR-I and their trough levels, its combinations with other immunosuppressive medications, and patients' profile, enabling clinicians to use these agents appropriately for maximum benefits. Recent randomized control trials have further increased the confidence of clinicians to use these agents in immediate posttransplant periods.
RESUMEN
Statin or 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) inhibitor is widely used and plays a vital role in the management of cardiovascular and cerebrovascular diseases. Statin is generally safe and its side effects are mostly mild and self-limiting. Immune-mediated necrotizing myositis (IMNM) is a rare and serious side effect characterized by the presence of anti-HMGCR inhibitor and myositis. Long-term immunosuppressive therapy is often required to manage it, and in refractory cases, the treatment can be very challenging. We report the case of a 55-year-old female with underlying diabetes mellitus and hyperlipidemia who developed refractory statin-induced IMNM despite being administered prednisolone, methotrexate, azathioprine, and immunoglobulin. After the introduction of rituximab, steroids were able to be tapered down to the lowest maintenance dose. Unfortunately, the patient subsequently succumbed to severe coronary artery disease (CAD) likely caused by the long-term steroid therapy, highlighting the difficulty and complications associated with the treatment of IMNM, especially in patients with cardiovascular risk factors.
RESUMEN
BACKGROUND: Patients with end-stage renal disease who developed H1N1 infections have an increased risk of morbidity and mortality. In light of the high incidence of H1N1 infections in renal replacement therapy patients in Brunei Darussalam, an Oseltamivir (Tamiflu) prophylactic dosing regimen of 75 mg every 5 days for renal replacement therapy patients was initiated by the Ministry of Health in August 2009. The regime was used to serve as a bridge towards an anticipated nationwide vaccination programme that was due in September 2009. This study aimed to evaluate the side effects, factors that might influence the side effects profile and compliance of the dialysis patients that had undergone the month-long chemoprophylactic regime. METHODS: A cross-sectional study was carried out on the dialysis patients that had undergone the oseltamivir prophylactic regime, which involved distribution of questionnaires to participants after the regime was completed. RESULTS: Three hundred and thirty-three patients participated in this study. 25.7% of sample participants reported at least one side effect (experienced during the regime). 97% of participants were found to have reported three side effect types or less. The most frequent side effects reported were nausea (9.4%), abdominal pain (9.1%) and dizziness (9.1%). Age, gender, dialysis types, serum haemoglobin, serum albumin and dialysis clearance measurements were found to have no significant associations with the frequency of participants that had reported side effects. 11.2% of sample participants made up the non-compliant group. The top two reasons for not completing the medication were participants' perceived side effects (24.3%) and forgetting to take their medications (56.8%). CONCLUSIONS: Side effects were found to be mild and tolerable by participants, with no life-threatening events. The study showed that high compliance of this regime can be achieved. These results, together with no incidence of H1N1 cases in the sample participants, showed that the dosing regimen of 75 mg every 5 days in both haemodialysis and continuous ambulatory peritoneal dialysis patients is both tolerable and effective and should be considered for future prophylactic regimes.
