INTRODUCTION

Acute coronary syndrome (ACS) and end-stage renal disease (ESRD) are both prevalent globally. The diagnosis and management of ACS in ESRD is difficult because the interplay of cardiovascular and renal disease is complicated. The guidelines for ACS may not be applicable to the ESRD population because the trials from which these are drawn mostly excluded ESRD patients.

To determine the clinical profile and outcomes of CKD patients on dialysis admitted for ACS in the Philippine General Hospital (PGH).

We did a retrospective cohort study and employed a retrospective review of electronic medical records among ESRD patients presenting with ACS in PGH from May 2021 to November 2023. The collected data was analyzed using univariate and bivariate statistics using PRISM software.

A total of 48 patients with ESRD were admitted for ACS in this study – 8 with STEMI and 40 with NSTEMI. The mean age was 61 years old and 33 (68.8%) were male. Among those with STEMI, six (75%) presented with Kilip II or more. While among those with NSTEMI, 17 (42.5%) had a GRACE score >140 and 27 (67.5%) had an NSTEMI TIMI risk score >2. On average, the patients were on hemodialysis for 31 months prior to admission. The most common comorbidities were hypertension (91.7%) and heart failure (83.3%). On admission, 18 (37.5%) presented with SBP >160, 7 (14.6%) patients presented with shock, and 4 (8.3%) patients presented with cardiac arrest. 38 (79.2%) patients had anemia on admission. 21 (43.8%) patients had left ventricular hypertrophy on electrocardiogram while 34 (70.8%) patients had cardiomegaly on chest radiography. The average left ventricular ejection fraction on echocardiogram was 46% and 27 (90%) patients had segmental wall motion abnormalities. The most common angiographic finding was 3-vessel coronary artery disease seen in 50% of patients. Almost all patients received dualantiplatelet therapy, high dose statin, and beta-blocker. The mortality rate was high at 43.8% with cardiovascular causes being the most common cause of death.

This study demonstrates the high mortality rate among patients with ESRD presenting with ACS. Our study portrays that patients with ESRD present with higher risk features including abnormalities in vital signs, laboratories, imaging, high prognostications score, and high in-hospital morbidity.

Valacyclovir-associated neurotoxicity (VAN) is a recognized adverse effect in elderly patients with renal impairment but remains underdiagnosed due to its nonspecific presentation and overlap with acute neurologic emergencies. We report a 78-year-old Filipino female with end-stage renal disease on maintenance hemodialysis who developed acute disorientation, agitation, vivid visual hallucinations and generalized weakness shortly after initiation of valacyclovir for herpes zoster. Given the abrupt onset of neuropsychiatric symptoms, viral encephalitis was initially considered. Magnetic resonance imaging of the brain showed no evidence of acute infarction or encephalitis, while electroencephalography demonstrated diffuse generalized slowing consistent with an encephalopathic process. Review of the medication history revealed valacyclovir dosing that exceeded recommendations for patients with end-stage renal disease. Valacyclovir was discontinued and emergent hemodialysis was initiated resulting in marked improvement in sensorium after the second session and complete resolution of symptoms after the third. This case shows VAN as an important diagnostic mimic of acute encephalopathy in elderly patients with renal failure and emphasizes the critical role of early medication review in preventing unnecessary investigations and enabling prompt, reversible management.

INTRODUCTION

Chronic Kidney Disease (CKD) is a leading cause of morbidity and mortality in the Philippines. Most Filipino CKD patients prefer hemodialysis due to barriers such as cost and availability of Kidney Transplant. End-stage kidney disease (ESKD) patients face high symptom burden and unmet palliative care needs. Even with advancement in dialysis technology, the annual mortality rate of dialysis patients remains between 20% and 25%. While Advance Care Planning (ACP) can help align care with patient preferences by facilitating discussions about values and future decisions, its utilization in dialysis population remains low due to barriers in implementation. There is limited research specifically addressing the preferences and influencing factors of Advance Care Planning among CKD patients on hemodialysis in the Philippines.

This study aimed to determine the ACP preferences of CKD patients undergoing hemodialysis and to identify the clinicodemographic factors associated with these preferences.

An analytic cross-sectional study was conducted involving 96 chronic kidney disease (CKD) patients undergoing hemodialysis at Baguio General Hospital and Medical Center (BGHMC) from October to November 2024. Data were collected using validated questionnaires administered either through face-to-face interviews or self-administration, depending on patients’ preferences and capabilities. Descriptive and inferential statistical methods were employed for data analysis.

The study revealed limited awareness of ACP among participants (86.5%), underscoring the need for education. Family-centered decision-making was prominent, with most participants preferring family members as surrogate decision-makers and confidants. Quality of life was prioritized over life extension, and preferences for “Do Not Resuscitate” (DNR) orders were notable. Educational attainment and ethnicity significantly influenced preferences, with higher education linked to greater awareness; and Ethnicity shaping preferences for decision-makers, confidants, timing of discussions, and resuscitation choices. Additionally, duration of dialysis was linked to care setting preferences, while social support systems influenced the preferred place for discussions.

The findings highlight critical associations between clinicodemographic factors and ACP preferences among hemodialysis patients. Addressing these associations through targeted education and culturally sensitive approach can promote high-quality end-of-life care, aligned with diverse patient needs, values, and preferences.

BACKGROUND

Diabetes mellitus (DM) is a significant and growing global health concern. Worldwide, 537 million adults have diabetes and 206 million of them are from the Western Pacific Region1. Local prevalence continues to remain high at 7.5%, with 4,303,899 adult Filipinos suffering from diabetes in 2021. DM significantly contributes to the growing burden of chronic kidney disease (CKD) worldwide with about 50% of end-stage renal disease (ESRD) being due to diabetic nephropathy alone. Likewise, 60% of Filipinos on maintenance dialysis have ESRD due to DM and hypertension. The primary care setting is the initial point of contact between healthcare providers and patients with type 2 diabetes, hence, the development of clinical practice guidelines that will provide guidance in caring for patients with stable complications of diabetes. The guideline is the first of 3 that are being developed by the Philippine Academy of Family Physicians for the diagnosis and management of adult patients with type 2 diabetes and stable microvascular complications – nephropathy, retinopathy and neuropathy.

This guideline aims to provide evidence-based recommendations on the diagnosis and management of adults with type 2 diabetes mellitus (T2DM) and early stage CKD and is divided into 5 main sections – Clinical Assessment, Diagnostic Tests, Pharmacologic Treatment, Non-pharmacologic Treatment and Patient Outcomes.

The method of guideline development followed the ADAPTE process. The Technical Working Group identified 19 key questions after consultation with colleagues and patients. Recommendations were adopted from high-quality clinical practice guidelines whenever applicable for most of the key clinical questions. On the other hand, the De Novo method of evidence review was used to answer key clinical questions for which recommendations from reviewed guidelines were not available. A modified GRADEPro was used in assessing the quality of evidence – high, moderate, low or very low. Following external review by a nephrologist, the draft recommendations were sent to the members of the consensus panel. Voting on whether to include or not by the consensus panel was facilitated to determine the strength of each recommendation – strong, moderate or weak.

After reviewing 3 high-quality clinical practice guidelines and the current evidence, the technical working group was able to develop 40 recommendations for the 19 key clinical questions.

Peripheral nerve block (PNB) has been successfully used as the sole anesthetic for Peritoneal dialysis (PD) catheter insertion, and has been shown to provide satisfactory anesthesia and analgesia perioperatively, especially among critically – ill patients.

This report describes the anesthetic management of an 18 – year old underweight patient with End-stage renal disease (ESRD) and decompensated heart failure who was scheduled for PD catheter insertion. He was given a left lateral Transversus abdominis plane (TAP) block and a right Rectus sheath (RS) block as the main anesthetic. Fifteen mL of Isobaric Bupivacaine 0.375% with Epinephrine 1:400,000 dilution was injected for the TAP block, and 10mL for the RS block, for a total volume of 25mL (93.7mg). Sedation was given via a Remifentanil infusion at 0.1mcg/kg/min. Intraoperatively, the patient was awake, conversant, and comfortable, no pressors were used, and no conversion to general anesthesia was done. Post-operatively, he had good pain control, with a pain score of 1/10, and successfully underwent dialysis via the PD catheter on the 2ndhospital day.

This pediatric patient who is critically ill is not a good candidate for general or neuraxial anesthesia due to the risk of hemodynamic instability and perioperative decompensation. PNB was done to provide anesthesia, and ensure good pain control post-operatively, and a right TAP and left RS were done instead of a bilateral TAP to lower the LA volume and decrease the risk of LA toxicity.

Unilateral TAP with contralateral RS is a safe anesthetic technique among critically-ill pediatric patients who will undergo PD catheter insertion without the risk of hemodynamic instability with general or neuraxial anesthesia.

OBJECTIVES: To explore the value of serum cystatin C (CysC) levels in evaluating renal prognosis in IgA nephropathy (IgAN) patients. METHODS: We retrospectively collected the clinical data of IgAN patients diagnosed by renal biopsy at Guangdong Provincial People's Hospital from January, 2014 to December, 2018. Based on baseline serum CysC levels, the patients were divided into high serum CysC (>1.03 mg/L) group and normal serum CysC (≤1.03 mg/L) group. The composite endpoint for poor renal prognosis was defined as ≥50% decline in estimated glomerular filtration rate (eGFR) and/or progression to end-stage renal disease (ESRD). Lasso regression, multivariate Cox regression and Kaplan-Meier survival analysis were used to identify the risk factors and compare renal survival rates between the two groups. Smooth curves fitting and threshold effect analysis were used to explore the relationship between serum CysC levels and the outcomes. A nomogram model was constructed and its predictive performance was evaluated using concordance index, calibration curve, receiver operating characteristic (ROC) curve and the area under curve (AUC). RESULTS: A total of 356 IgAN patients were enrolled, who were followed up for 4.65±0.93 years. The composite endpoint occurred in 74 patients. High serum CysC was identified as an independent risk factor for poor renal prognosis in IgAN (HR=2.142, 95% CI 1.222 to 3.755), and the patients with high serum CysC levels had a lower renal survival rate (Log-rank χ²=47.970, P<0.001). In patients with serum CysC below 2.12 mg/L, a higher CysC level was associated with an increased risk of poor renal prognosis (β=3.487, 95% CI: 2.561-4.413, P<0.001), while above this level, the increase of the risk was not significant (β=0.676, 95% CI: -0.642-1.995, P=0.315). The nomogram model based on serum CysC and 3 other independent risk factors demonstrated good internal validity with a concordance index of 0.873 (95% CI: 0.839-0.907) and an AUC of 0.909 (95% CI: 0.873-0.945). CONCLUSIONS Serum CysC levels are associated with renal prognosis in IgAN patients, and high serum CysC an independent risk factor for poor renal prognosis.

OBJECTIVES: To investigate the effect of serum advanced glycation endproducts (AGEs) on stenosis after first autologous arteriovenous fistula (AVF) in patients with end-stage renal disease (ESRD). METHODS: Patients with ESRD undergoing standard native arteriovenous fistula (AVF) for the first time in the Department of Nephrology, Affiliated Hospital of Guilin Medical University from February to June 2022 were prospectively enrolled. The preoperative general data, clinical examination results and ultrasound data of the operated limbs were collected. The patients with and without stenosis within 2 months after the operation were compared for preoperative serum AGEs levels detected using ELISA and the clinical parameters. Logistic regression analysis was used to analyze the independent risk factors of AVF stenosis, and the sensitivity and specificity of AGEs for predicting postoperative stenosis were analyzed using receiver-operating characteristic (ROC) curve. RESULTS: Of the 94 patients enrolled, 34 had postoperative arteriovenous stenosis and 60 had no stenosis. The number of diabetic patients differed significantly between stenosis group and non-stenosis group (P<0.001). Serum AGEs levels, which were negatively correlated with serum phosphorus level (P<0.05), were significantly higher in stenosis group than in non-stenosis group (Z=-2.837, P=0.005). Serum AGE level was an independent risk factor for postoperative stenosis after AVF (OR=1.251, 95% CI:1.096-1.423, P<0.001). For predicting AVF stenosis, the area under the ROC curve (AUC) of AGEs was 0.677 (P=0.007, 95% CI: 0.572-0.770), with a specificity of 90.00% and a sensitivity of 52.94% at the optimal cut-off value of 8.43 µg/mL; AGEs combined with fibrinogen had an AUC of 0.763 (P<0.001, 95% CI: 0.664-0.844), with a specificity of 73.33% and a sensitivity of 70.59% at the optimal cut-off value of 0.30. CONCLUSIONS Elevated serum AGEs level is an independent risk factor for postoperative AVF stenosis, and its combination with fibrinogen has a better efficacy for predicting postoperative AVF stenosis.

Long-term exposure to particulate matter has been increasingly implicated in the progression of chronic kidney disease (CKD). However, its impact on IgA nephropathy (IgAN), a leading cause of end-stage renal disease (ESRD), remains unclear. A total of 1768 IgAN patients, confirmed by renal biopsy were included in this cohort study. Long-term exposure to PM_2.5 and PM₁₀ was assessed using high-resolution satellite-based data from the China High Air Pollutants (CHAP) dataset. Cox proportional hazards models were used to estimate the associations between PM_2.5 or PM₁₀ and ESRD risk, adjusting for demographic, clinical, and biochemical covariates. Over a median follow-up of 3.63 years, 209 participants progressed to ESRD. Higher exposure to both PM_2.5 and PM₁₀ was significantly associated with an increased risk, with hazard ratios of 1.62 and 1.36 per 10 µg/m³ increase, respectively. A nonlinear dose-response relationship was observed, with risk increasing markedly beyond threshold levels. Trajectory modeling of prebaseline exposure identified a subgroup with persistently high and fluctuating particulate matter exposure that showed the highest risk. This study provides strong evidence that prolonged exposure to ambient particulate matter contributes to renal disease progression in individuals with IgAN.

Peritoneal dialysis (PD) is one of the main renal replacement therapy methods for patients with end-stage chronic kidney disease, and peritoneal dialysis belt is a key auxiliary device. However, there are some problems in the existing PD technology, such as the separation of heating system and dialysate system, the inability to continuously heat dialysate and the single function of peritoneal dialysis belt. In order to solve the above problems, the staff of Shanghai Geriatric Medical Center designed an intelligent temperature-controlled peritoneal dialysis belt and obtained the National Utility Model Patent of China (patent number: ZL 2023 2 1815961.9). The intelligent temperature-controlled peritoneal dialysis belt is composed of a double-layer fixed belt, an intelligent temperature control system (including temperature control structure and intelligent control system) and other auxiliary structures. The peritoneal dialysis tube can penetrate into the dissection from the entry of the inner surface of the fixed belt and pass through the exit of the outer surface. The double-layer fixed belt ensures the stable fixation of the dialysis tube. The two ends of the fixing belt are designed with magic stickers to adjust the tightness of the fixing belt to adapt to people with different waist circumferences. The interlayer is equipped with an intelligent temperature control system, which can continuously heat the dialysate through an electric heating plate to maintain a temperature close to the body temperature. Through the display screen and controller on the intelligent control system, medical staff can be allowed to monitor and adjust the temperature, pressure and flow parameters of the dialysate in real time. In addition, a cloth with a pulling chain is designed on the inner surface of the fixed belt, and the cloth is opened to facilitate the medical staff to wear the peritoneal dialysis tube in the temperature control structure or the restraint belt. The intelligent temperature-controlled peritoneal dialysis belt enhances the effectiveness of PD, saves PD resources, improves the convenience of PD, is suitable for family and hospital use, can effectively improve the quality of life of patients with chronic renal failure, and is suitable for clinical promotion.

BACKGROUND

A patent and functional vascular access (VA) is the lifeline of hemodialysis patients. Prevention of VA failure and maintaining patency are crucial to ensure efficient dialysis, reduce morbidity, lessen healthcare costs and improve patient outcomes. This study aims to determine the risk factors of VA failure among hemodialysis dependent end-stage renal disease (ESRD) patients.

This is a retrospective, case-control study conducted between July 2022 and December 2022. One hundred forty six ESRD patients consisting of 73 with VA failure and 73 without VA failure, undergoing hemodialysis in Manila Doctors Hospital (MDH) - Hemodialysis Unit were included in the study. At least one age (up to 5 years or younger) and sex-matched control was recruited per case (1:1 case-control sampling). The relation of patient demographic profile, smoking, comorbidities (ie, hypertension, diabetes, dyslipidemia, coronary artery disease [CAD], peripheral artery disease [PAD] and heart failure [HF]), duration of dialysis, location of VA, preoperative vessel diameter and arterial peak systolic velocity (PSV) and history of central vein catheterization to VA failure were analyzed. Odds ratio and their 95% confidence interval (CI) for the association of risk factors to VA failure were calculated.

Based on univariate analysis, the following are significant risk factors for VA failure: diabetes (OR 2.35, CI 1.20-4.62), CAD (OR 3.58, CI 1.58-8.13) and PAD (OR 3.04, CI 1.11-8.29). On multivariate analysis, two variables are significant risk factors associated with VA failure, namely: heart failure (OR 7.3, CI 2.15-21.4) and history of ipsilateral central venous catheter (OR 5.51, CI 1.99-15.3) (p = 0.05). Distal radiocephalic VAs have higher failure rates (53.42%) than proximal brachiocephalic (23.36%) and brachiobasilic (8.22%).

Diabetes, CAD, PAD, HF and history of ipsilateral central vein catheterization are significant risk factors for VA failure. Distal VA has higher failure rates compared to proximal access in these high-risk patients. This information may guide clinicians in making the appropriate recommendation regarding location of VA in this subset of patients. Aside from patient comorbidities, inherent characteristics, patency and functionality of VA vessels may be influenced by other extrinsic factors leading to VA failure.
