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.

This study aims to explore the medication rules and mechanisms of treating chronic renal failure(CRF) by Jinling medical school based on data mining, network pharmacology, and experimental validation systematically and deeply. Firstly, the study selected the papers published by the inherited clinicians in Jinling medical school in Chinese journals using the subject headings named "traditional Chinese medicine(TCM) + chronic renal failure", "TCM + chronic renal inefficiency", or "TCM + consumptive disease" in China National Knowledge Infrastructure, Wanfang, and VIP Chinese Science and Technology Periodical Database and screened TCM formulas for treating CRF according to inclusion and exclusion criteria. The study analyzed the frequency of use of single TCM and the four properties, five tastes, channel tropism, and efficacy of TCM used with high frequency and performed association rule and clustering analysis, respectively. As a result, a total of 215 TCM formulas and 235 different single TCM were screened, respectively. The TCM used with high frequency included Astragali Radix, Rhei Radix et Rhizoma, Salviae Miltiorrhizae Radix et Rhizoma, Poria, and Atractylodis Macrocephalae Rhizoma(top 5). The single TCM characterized by "cold properties, sweet flavor, and restoring spleen channel" and the TCM with the efficacy of tonifying deficiency had the highest frequency of use, respectively. Then, the TCM with the rules of "blood-activating and stasis-removing" and "diuretic and dampness-penetrating" appeared. In addition, the core combination of TCM [(Hexin Formula, HXF)] included "Astragali Radix, Rhei Radix et Rhizoma, Poria, Salviae Miltiorrhizae Radix, and Angelicae Sinensis Radix". The network pharmacology analysis showed that HXF had 91 active compounds and 250 corresponding protein targets including prostaglandin-endoperoxide synthase 2(PTGS2), PTGS1, sodium voltage-gated channel alpha subunit 5(SCN5A), cholinergic receptor muscarinic 1(CHRM1), and heat shock protein 90 alpha family class A member 1(HSP90AA1)(top 5). Gene Ontology(GO) function analysis revealed that the core targets of HXF predominantly affected biological processes, cellular components, and molecular functions such as positive regulation of transcription by ribonucleic acid polymerase Ⅱ and DNA template transcription, formation of cytosol, nucleus, and plasma membrane, and identical protein binding and enzyme binding. Kyoto Encyclopedia of Genes and Genomes(KEGG) analysis revealed that CRF-related genes were involved in a variety of signaling pathways and cellular metabolic pathways, primarily involving "phosphatidylinositol 3-kinase(PI3K)-protein kinase B(Akt) pathway" and "advanced glycation end products-receptor for advanced glycation end products". Molecular docking results showed that the active components in HXF such as isomucronulatol 7-O-glucoside, betulinic acid, sitosterol, and przewaquinone B might be crucial in the treatment of CRF. Finally, a modified rat model with renal failure induced by adenine was used, and the in vivo experimental confirmation was performed based on the above-mentioned predictions. The results verify that HXF can regulate mitochondrial autophagy in the kidneys and the PI3K-Akt-mammalian target of rapamycin(mTOR) signaling pathway activation at upstream, so as to alleviate renal tubulointerstitial fibrosis and then delay the progression of CRF.

OBJECTIVES: To summarize the clinical and genetic characteristics of end-stage renal disease caused by PLCE1 gene mutations. METHODS: A retrospective analysis of the clinical and genetic features of three children from a family with PLCE1 gene mutations was conducted, along with a literature review of hereditary kidney disease cases caused by PLCE1 gene mutations. RESULTS: The proband was an 8-year-old male presenting with nephrotic syndrome stage 4 chronic kidney disease. Renal biopsy showed focal segmental glomerulosclerosis. Two years and five months after kidney transplantation, the patient had persistent negative proteinuria and normal renal function. Whole-exome sequencing identified two pathogenic heterozygous variants: c.961C>T and c.3255_3256delinsT, with c.3255_3256delinsT being a novel mutation. Family screening revealed no renal involvement in the parents, but among five siblings, one brother died at age of 4 years from end-stage renal disease. A 7-year-old sister presented with proteinuria and bilateral medullary sponge kidney, with proteinuria resolving after one year of follow-up. A 3-year-old brother died after kidney transplantation due to severe pneumonia. The literature review included 45 patients with hereditary kidney disease caused by PLCE1 gene mutations. The main clinical phenotype was nephrotic syndrome (87%, 39/45), and renal pathology predominantly showed focal segmental glomerulosclerosis (57%, 16/28). No mutation hotspots were identified. CONCLUSIONS Compound heterozygous mutations in the PLCE1 gene can lead to rapid progression of the disease to end-stage renal disease, with favorable outcomes following kidney transplantation. Family screening is crucial for early diagnosis, and medullary sponge kidney may be a novel phenotype associated with these gene mutations.

OBJECTIVE: To explore the mechanism of colon dialysis with Yishen Decoction (YS) in improving the autophagy disorder of intestinal epithelial cells in chronic renal failure (CRF) in vivo and in vitro. METHODS: Thirty male SD rats were randomly divided into normal, CRF, and colonic dialysis with YS groups by a random number table method (n=10). The CRF model was established by orally gavage of adenine 200 mg/(kg•d) for 4 weeks. CRF rats in the YS group were treated with colonic dialysis using YS 20 g/(kg•d) for 14 consecutive days. The serum creatinine (SCr) and urea nitrogen (BUN) levels were detected by enzyme-linked immunosorbent assay. Pathological changes of kidney and colon tissues were observed by hematoxylin and eosin staining. Autophagosome changes in colonic epithelial cells was observed with electron microscopy. In vitro experiments, human colon cancer epithelial cells (T84) were cultured and divided into normal, urea model (74U), YS colon dialysis, autophagy activator rapamycin (Ra), autophagy inhibitor 3-methyladenine (3-MA), and SIRT1 activator resveratrol (Re) groups. RT-PCR and Western blot were used to detect the mRNA and protein expressions of zonula occludens-1 (ZO-1), Claudin-1, silent information regulator sirtuin 1 (SIRT1), LC3, and Beclin-1 both in vitro and in vivo. RESULTS: Colonic dialysis with YS decreased SCr and BUN levels in CRF rats (P<0.05), and alleviated the pathological changes of renal and colon tissues. Expressions of SIRT1, ZO-1, Claudin-1, Beclin-1, and LC3II/I were increased in the YS group compared with the CRF group in vivo (P<0.05). In in vitro study, compared with normal group, the expressions of SIRT1, ZO-1, and Claudin-1 were decreased, and expressions of Beclin-1, and LC3II/I were increased in the 74U group (P<0.05). Compared with the 74U group, expressions of SIRT1, ZO-1, and Claudin-1 were increased, whereas Beclin-1, and LC3II/I were decreased in the YS group (P<0.05). The treatment of 3-MA and rapamycin regulated autophagy and the expression of SIRT1. SIRT1 activator intervention up-regulated autophagy as well as the expressions of ZO-1 and Claudin-1 compared with the 74U group (P<0.05). CONCLUSION Colonic dialysis with YS could improve autophagy disorder and repair CRF intestinal mucosal barrier injury by regulating SIRT1 expression in intestinal epithelial cells.

OBJECTIVES: End stage renal disease (ESRD) is a major disease that seriously threatens the health of young people, and kidney transplantation is an effective treatment method to improve its prognosis.Young ESRD patients at a critical stage of life development often face significant physical and psychological challenges while waiting for kidney transplantation. Their psychological state directly affects treatment compliance and transplantation outcomes.This study aims to explore the psychological experiences of young patients with end stage renal disease during the waiting period for kidney transplantation, and provide a reference for formulating relevant psychological intervention measures. METHODS: A descriptive qualitative research design was adopted. Using purposive sampling, 20 young ESRD patients awaiting for kidney transplantation at the Transplantation Center of Xiangya Third Hospital, Central South University, from June to August 2024, were recruited. Based on the socio-ecological systems theory, a semi-structured interview outline was developed, and directed content analysis was applied to analyze the interview data. RESULTS: According to the results of qualitative interviews, 3 themes and 9 sub-themes were summarized as follows: Microsystem (disease pain experience, anxiety during transplantation waiting period, cognitive differentiation and coping differences), mesosystem (imbalance of family roles and dependent guilt, physician-patient trust dynamics, ambivalence toward peer support), and macrosystem (decision-making powerlessness caused by information asymmetry, sociocultural stigma and public bias, institutional dependence and passive behavior). CONCLUSIONS Young ESRD patients experience complex psychological experiences during the waiting period for kidney transplantation. Healthcare providers should explore corresponding intervention measures based on patients' psychological status to improve their waiting period experience and promote both physical and mental health.

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.
