RESUMEN
BACKGROUND: Sodium-glucose transporter-2 inhibitors (SGLT-2i) are recommended for use in patients with type 2 diabetes comorbid atherosclerotic cardiovascular disease, heart failure, or chronic kidney disease. Limited reports are currently available for their use in dialysis patients. In an observational, retrospective follow-up study, we reported the clinical characteristics of chronic peritoneal dialysis (PD) patients on SGLT-2i. METHODS: We enrolled 50 diabetic chronic PD patients, and 11 continued SGLT-2i after PD treatment. We reported the patients' ultrafiltration, HbA1c, urinary tract infection episodes, and venous CO2 during follow-up and compared the differences in these factors between patients with and without SGLT-2i. RESULTS: The mean age of the patients was 65 ± 15 years, and 16 (32%) patients were female. The age, gender, heart failure, and primary kidney disease were not different between patients with and without SGLT-2i at enrollment. In an average of 31 months follow-up, patients with SGLT-2i had higher ultrafiltration (1322 ± 200 ml/day vs. 985 ± 415 ml/day, p = 0.013), hemoglobin (11.2 ± 1.7 vs. 10.2 ± 1.7 g/dl), white blood cell count (9.2 ± 3.7 vs. 7.4 ± 2.1 109/L), and a lower venous CO2 (p = 0.036). The urine amount, the overall survival, the technical survival, and the chance of UTI were not different between patients with and without SGLT2i. CONCLUSION: SGLT-2i may increase ultrafiltration volume and hemoglobin levels in chronic PD patients. SGLT-2i did not increase urinary tract infection but was linked to subclinical metabolic acidosis. WHAT WAS KNOWN: The effect of SGLT-2i in chronic PD patients is not clear? THIS STUDY ADDS: SGLT-2i is associated with increased ultrafiltration, hemoglobin, white blood cell counts, and a decreased CO2 in PD patient. POTENTIAL IMPACT: SGLT-2i may increase ultrafiltration in PD patients.

BACKGROUND: Adequate fluid removal to achieve euvolemic status can be difficult in patients with incident peritoneal dialysis (PD). Limited treatments such as increased high dextrose PD solutions and icodextrin are currently available. We reported four incident PD patients whose' ultrafiltration volume was increased after sodium-glucose cotransporter-2 inhibitors. CASE PRESENTATION: The four reported cases were diabetic kidney disease stage 5 (cases 1-3) and IgA nephritis (case 4) patients whostartedt PD because of acute pulmonary edema (case 1 and 3), nausea vomiting (case 2), and hyperkalemia (case 4). They had an ultrafiltration volume of 700-1000 ml per day but hpersistentted peripheral pitting edema or pulmonary edema. Their ultrafiltration volincreased after dapagliflozin 5 mg daily, and the fluid overload symptoms ere improved. No hypotension, or hypoglycemia was found, and the urine was not increased during dapagliflozin treatment. CONCLUSIONS: SGLT-2 inhibitors may increase ultrafiltration in incident PD patients. More studies are needed to support the safety of SGLT-2 inhibitors in PD patients.

Urothelial carcinoma (UC) is the ninth most prevalent malignancy worldwide. Noninvasive and efficient biomarkers with high accuracy are imperative for the surveillance and diagnosis of UC. CKD patients were enrolled as a control group in this study for the discovery of highly specific urinary protein markers of UC. An iTRAQ-labeled quantitative proteomic approach was used to discover novel potential markers. These markers were further validated with 501 samples by ELISA assay, and their diagnostic accuracies were compared to those of other reported UC markers. BRDT, CYBP, GARS, and HDGF were identified as novel urinary UC biomarkers with a high discrimination ability in a population comprising CKD and healthy subjects. The diagnostic values of the four novel UC markers were better than that of a panel of well-known or FDA-approved urinary protein markers CYFR21.1, Midkine, and NUMA1. Three of our discovered markers (BRDT, HDGF, GARS) and one well-known marker (CYFR21.1) were finally selected and combined as a marker panel having AUC values of 0.962 (95% CI, 0.94-0.98) and 0.860 (95% CI, 0.83-0.89) for the discrimination between UC and normal groups and UC and control (healthy + CKD) groups, respectively.

OBJECTIVE: Temporary vascular access (TVA) is frequently used during the first dialysis in patients with chronic kidney disease (CKD), and it is associated with an increased risk of infection, central vein stenosis, and mortality. Here, factors associated with TVA in patients with CKD were explored. METHODS: This study included patients in a single-center CKD care program who initiated long-term renal replacement therapy. The primary outcome was TVA use at first dialysis. Factors possibly associated with TVA use were analyzed using Cox regression. RESULTS: Temporary vascular access was used in 53.2% of the patients at first dialysis. In total, 73.2% (n = 865) and 26.8% (n = 317) of the patients were on hemodialysis and peritoneal dialysis, respectively. Multivariate Cox regression analysis showed that TVA use in patients with CKD was associated with diabetes (hazard ratio [HR] 1.52, 95% confidence interval [CI] 1.28-1.81, p < 0.001), lower albumin (HR 0.82, 95% CI 0.75-0.91, p < 0.001), lower education level (HR 0.75, 95% CI 0.56-1.00, p = 0.055), and total care dependency (HR 1.92, CI 1.44-3.43, p = 0.003). CONCLUSION: Diabetes, education level, and care dependency are associated with TVA at dialysis initiation in patients with CKD.

BACKGROUND: Bacterial cultures allow the identification of infectious disease pathogens. However, obtaining the results of conventional culture methods is time-consuming, taking at least two days. A more efficient alternative is the use of concentrated bacterial samples to accelerate culture growth. Our study focuses on the development of a high-yield sample concentrating technique. RESULTS: A total of 71 paired samples were obtained from patients on peritoneal dialysis (PD). The peritoneal dialysates were repeat-centrifuged and then washed with saline, namely the centrifuging and washing method (C&W method). The concentrated samples were Gram-stained and inoculated into culture plates. The equivalent unprocessed dialysates were cultured as the reference method. The times until culture results for the two methods were compared. The reference method yielded no positive Gram stain results, but the C&W method immediately gave positive Gram stain results for 28 samples (p < 0.001). The culture-negative rate was lower in the C&W method (5/71) than in the reference method (13/71) (p = 0.044). The average time for bacterial identification achieved with the C&W method (22.0 h) was shorter compared to using the reference method (72.5 h) (p < 0.001). CONCLUSIONS: The C&W method successfully concentrated bacterial samples and superseded blood culture bottles for developing adequate bacterial cultures. The C&W method may decrease the culture report time, thus improving the treatment of infectious diseases.

BACKGROUND: Urothelial cancer (UC) includes carcinomas of the bladder, ureters, and renal pelvis. New treatments and biomarkers of UC emerged in this decade. To identify the key information in a vast amount of literature can be challenging. In this study, we use text mining to explore UC publications to identify important information that may lead to new research directions. METHOD: We used topic modeling to analyze the titles and abstracts of 29,883 articles of UC from Pubmed, Web of Science, and Embase in Mar 2020. We applied latent Dirichlet allocation modeling to extract 15 topics and conducted trend analysis. Gene ontology term enrichment analysis and Kyoto encyclopedia of genes and genomes pathway analysis were performed to identify UC related pathways. RESULTS: There was a growing trend regarding UC treatment especially immune checkpoint therapy but not the staging of UC. The risk factors of UC carried in different countries such as cigarette smoking in the United State and aristolochic acid in Taiwan and China. GMCSF, IL-5, Syndecan-1, ErbB receptor, integrin, c-Met, and TRAIL signaling pathways are the most relevant biological pathway associated with UC. CONCLUSIONS: The risk factors of UC may be dependent on the countries and GMCSF, IL-5, Syndecan-1, ErbB receptor, integrin, c-Met, and TRAIL signaling pathways are the most relevant biological pathway associated with UC. These findings may provide further UC research directions.

RATIONALE: Chronic pancreatitis (CP) is a pancreatic disease with poor prognosis and pancreatic cancer (PC) is one of the most lethal types of cancer that is symptomless in the early stage. Because the clinical and image findings of CP can overlap that of pancreatic cancer (PC) which leads to confusion in the diagnosis and treatment of PC, discovery/verification/validation of more accurate protein biomarkers to diagnose CP and PC is in urgent need. METHODS: The PubMed, Web of Science, and Google Scholar were searched using the keywords: 'biomarker', 'marker', 'chronic pancreatitis', "pancreatic cancer" or "proteomics" for highly related researches. We focused on the articles published after the year 2005 in this review. RESULTS: We introduce the background to CP and PC and summarize the diagnosis of CP and PC, analytically validated protein biomarkers, and proteomic approaches for discovery/verification/validation. The potential use of mass spectrometry (MS) in clinical diagnosis is also discussed. CONCLUSIONS: Continuously improving sensitivity of MS can provide deeper proteome for new marker discovery and high reliability for protein marker verification, validation, and clinical diagnosis. The analytically validated protein markers could be considered as targeted protein biomarkers for developing a MS platform in the clinical validation process or clinical diagnosis of CP and PC.

OBJECTIVE: The association between asthma and benign prostatic hyperplasia (BPH) has rarely been explored. We investigated whether male asthmatic patients had an increased risk of BPH by conducting this retrospective nationwide population-based study. METHODS: We utilized data derived from the National Health Insurance Research Database (NHIRD) in Taiwan. A total of 9778 male patients aged >40 years who were newly diagnosed with asthma between 2000 and 2006 were included in the asthma group. Male enrollees without asthma were selected as the non-asthma group from the same database. Both the groups were followed up until the end of 2013. We performed Cox proportional hazard regression analysis to estimate the risk of BPH and transurethral resection of the prostate (TURP) in the male patients with asthma compared with that in those without asthma. RESULTS: The risk of BPH and TURP in the asthma group was 1.40-fold (95% confidence interval [CI] = 1.30-1.42) and 1.30-fold (95% CI= 1.31-1.50) higher than that in the non-asthma group, respectively, after adjusting for comorbidities, relevant medications and number of annual outpatient visits. CONCLUSIONS: The male patients with asthma were found to have a higher risk of BPH than did those without asthma.

BACKGROUND: Hypokalemia is a common clinical problem. The association between urinary tract infection (UTI) and hypokalemia is not clear. Hypokalemia is common in patients with UTI in clinical observation. The aim of the study is to determine if UTI is associated with hypokalemia. METHODS: Patients hospitalized with UTI and the control group were retrieved from the Longitudinal Health Insurance Database 2005. The control group was patients hospitalized with other reasons and were matched for the confoundings of UTI and hypokalemia. We analyze the risk of hypokalemia using logistic regression and calculate the odds ratio (OR) and 95% confidence interval (CI) of OR. RESULTS: We analyzed 43,719 UTI patients and control patients. Hypokalemia was found in 4540 (10.4%) patients with UTI and 1842 (4.2%) control patients. The percentage of patients with hypokalemia was higher in UTI patients (chi-square, p < 0.001). UTI was associated with hypokalemia and the odds ratio (OR) was 2.27 [95% confidence interval (CI): 2.17-2.41]. Cerebrovascular accident, chronic obstructive pulmonary disease, hypertension, congestive heart failure, diarrhea, medications including thiazides, sulfonamides, xanthines, and laxatives were independently associated with hypokalemia. Recurrent UTI was associated with hypokalemia in UTI patients (OR: 1.13, 95% CI: 1.05-1.23, p < 0.001). CONCLUSIONS: Urinary tract infection is associated with hypokalemia among inpatients. The association is independent of patients' comorbidities and medications. Recurrent UTI is associated with increased hypokalemia in UTI patients.

BACKGROUND: Acute Kidney Injury (AKI) is common among inpatients. Severe AKI increases all-cause mortality especially in critically ill patients. Older patients are more at risk of AKI because of the declined renal function, increased comorbidities, aggressive medical treatments, and nephrotoxic drugs. Early prediction of AKI for older inpatients is therefore crucial. METHODS: We use 80 different laboratory tests from the electronic health records and two types of representations for each laboratory test, that is, we consider 160 (laboratory test, type) pairs one by one to do the prediction. By proposing new similarity measures and employing the classification technique of the K nearest neighbors, we are able to identify the most effective (laboratory test, type) pairs for the prediction. Furthermore, in order to know how early and accurately can AKI be predicted to make our method clinically useful, we evaluate the prediction performance of up to 5 days prior to the AKI event. RESULTS: We compare our method with two existing works and it shows our method outperforms the others. In addition, we implemented an existing method using our dataset, which also shows our method has a better performance. The most effective (laboratory test, type) pairs found for different prediction times are slightly different. However, Blood Urea Nitrogen (BUN) is found the most effective (laboratory test, type) pair for most prediction times. CONCLUSION: Our study is first to consider the last value and the trend of the sequence for each laboratory test. In addition, we define the exclusion criteria to identify the inpatients who develop AKI during hospitalization and we set the length of the data collection window to ensure the laboratory data we collect is close to the AKI time. Furthermore, we individually select the most effective (laboratory test, type) pairs to do the prediction for different days of early prediction. In the future, we will extend this approach and develop a system for early prediction of major diseases to help better disease management for inpatients.

BACKGROUND: Glomerular filtrate rate (GFR) decline is associated with increased risk of dialysis in patients with chronic kidney disease (CKD). It is unclear whether the maximum, the minimum, or the average of GFR decline rate is associated with the risk of mortality and the initiation of renal replacement therapy (RRT). We investigated prognostic role of the maximum, the minimum, and the average of GFR decline rate in patients with CKD not yet on dialysis. METHODS: Patients, enrolled in the CKD program of China Medical University Hospital between July 2004 and Aug 2013, with CKD stages 3-5 (estimated GFR [eGFR] < 60 mL/min/1.73 m2) not yet on dialysis were analyzed. Primary outcome was a composite of mortality and RRT. The association between 3 readings of GFR decline rate and primary outcome was analyzed using Cox proportional hazard regression. RESULTS: We analyzed 815 patients aged 75 (interquartile range [IQR] 65-82) years with a median follow-up of 5.2 years (IQR 3.9-6.9). The maximum of eGFR decline rate was associated with the primary outcome (hazard ratio 2.19, 95% CI 1.16-4.12, p = 0.015), independent of age, gender, diabetes, cerebrovascular accident, smoking, baseline eGFR, serum albumin, calcium, urine protein/creatinine ratio, usage of renin-angiotensin system blockade. The minimum and the average of eGFR decline rate were not associated with the primary outcome. CONCLUSIONS: The maximum of GFR decline rate was associated with mortality and poor renal outcome in CKD patients, independent of other contributive confounders.

AIM: Abdominal aortic calcification (AAC) score in dialysis patients was associated with coronary artery disease (CAD) in cross-sectional study, but the use of AAC score in the CAD prediction was not clear. We aimed to use AAC score in the estimation of CAD occurrence in middle-aged peritoneal dialysis (PD) patients. METHODS: Middle-aged (45-65 years old) PD patients were recruited and followed up until CAD occurrence, patient mortality, or PD failure. We quantified AAC score by lateral lumbar radiography, and used receiver operation curve (ROC) analysis to find the cut-off value for CAD prediction. RESULTS: There were 187 patients recruited for study with a mean follow-up of 1027 ± 427 days. AAC score in patients with CAD during follow-up period (9.7 ± 7.6, n = 41) was higher than in patients without CAD occurrence (5.5 ± 6.1, n = 146) (P < 0.001). Multivariate hazard ratio of AAC score for CAD was 1.07 (P = 0.044). ROC showed that AAC score of 5.5 had a sensitivity of 0.667 and a specificity of 0.581 in the prediction of CAD occurrence. Patients with AAC score above 5.5 had significantly higher cumulative incidence of CAD than patients with AAC score below 5.5 (Log-rank test, P = 0.003). Age (P = 0.002), diabetes (P = 0.002), hypertension (P = 0.032), longer dialysis vintage (P < 0.001) and lower serum potassium (P = 0.012) were parameters significantly associated with higher AAC score. CONCLUSION: AAC score can predict CAD occurrence in PD patients. Age, diabetes, hypertension, dialysis vintage and serum potassium level are factors associated with higher AAC score.

AIM: The prevalence of hypothyroidism is high in haemodialysis (HD) patients and hypothyroidism increases all-cause mortality in HD patients. Comorbidities are common in HD patients and are associated with both mortality and hypothyroidism. The aim of the study is to explore the effect of the interactions of comorbidities and hypothyroidism on all-cause mortality in HD patients. METHOD: Patients with hypothyroidism (ICD-9-CM 244.0, 244.1, and 244.9) and matched patients without hypothyroidism in the Registry for Catastrophic Illness Patient Database of Taiwan Health Insurance from 2000 to 2010 were analyzed. The association of hypothyroidism and risk of all-cause mortality was analyzed using Cox proportional hazard regression. RESULT: Nine hundred and eight HD patients with hypothyroidism and 3632 sex-, age-, gender- matched HD patients without hypothyroidism were analyzed. Hypothyroidism was associated with increased all-cause mortality with an adjusted hazard ratio of 1.22 [95% confidence interval (CI): 1.10-1.36, P < 0.001]. TRT may decrease mortality associated with hypothyroidism (P < 0.001). There was a significant interaction (P = 0.04) between diabetes and hypothyroidism. There was no significant interaction found in hypothyroidism and the following comorbidities: hyperlipidaemia, hypertension, chronic obstructive pulmonary disease, coronary artery disease, stroke, peripheral arterial disease, asthma, congestive heart failure and cancer. CONCLUSION: Hypothyroidism is associated with increased all-cause mortality in chronic HD patients. The interaction of hypothyroidism and diabetes, but not other common comorbidities in HD patients, has an effect on mortality risks.

BACKGROUND: Abdominal aortic calcification (AAC) has been known to be associated with cardiovascular mortality in hemodialysis. However, the association between AAC and future coronary artery disease (CAD) occurrence is not clear. We aimed to clarify the association of AAC severity and the occurrence of future CAD events in hemodialysis patients. METHODS: Hemodialysis (HD) patients were recruited in this prospective cohort study. AAC severity was quantified by AAC score, which was measured by lateral lumbar radiography. We used receiver operation curve (ROC) analysis to find the cutoff AAC value for CAD prediction. CAD-free survival was analyzed by Kaplan-Meier study. RESULTS: There were 303 patients recruited for study with a median (interquartile range) follow-up of 95 (65-146) months. The AAC score in patients with occurrence of new CAD [9 (3-15.25), n = 114] was higher than in patients without new CAD occurrence [5 (1-9) n = 189], p < 0.001. Multivariate hazard ratio of AAC score for CAD was 1.039 (p = 0.016). ROC study showed that an AAC score of 5.5 had a sensitivity of 0.658 and a specificity of 0.587 in the prediction of new CAD occurrence. Patients with AAC score above 5.5 had significantly higher cumulative incidence of CAD than patients with AAC score below 5.5. Age, diabetes, prior history of CAD, and longer dialysis vintage were major factors associated with higher AAC score. CONCLUSIONS: AAC score can predict the occurrence of future CAD events in HD patients. The best cut-off value of AAC score is 5.5. AAC score greater than 5.5 is a reliable abdominal aortic calcification marker, and can predict future CAD in ESRD patients. Major contributive factors for higher AAC score were age, presence of diabetes, prior history of CAD, and longer dialysis vintage.

OBJECTIVES: Systemic inflammation has been reported to be associated with uremic pruritus (UP). Although a vegetarian diet can reduce systemic inflammation in hemodialysis patients, the effect of vegetarian diet on UP is not clear. The purpose of the study was to know the possible effects of vegetarian diet on UP. METHODS: A cross-sectional study was done to compare the severity of UP and blood levels of systemic inflammatory markers between vegetarian and non-vegetarian hemodialysis patients. Six non-vegetarian patients with uremic pruritus changed their non-vegetarian diet to vegetarian diet for 2 months. Visual Analogue Scale (VAS) and pruritus score (PS) were used to measure the UP severity. The serum high-sensitivity C-reactive protein (hs-CRP), and interleukin-2 (IL-2) were used as markers of inflammation. RESULTS: Both the median VAS scores (p = .043) and the median PS scores (p < .001) were lower in the Vegetarian than in the non-vegetarian group. The median values of hs-CRP in Vegetarian were lower than that for the non-vegetarian (p = .020). The median value of IL-2 was also lower in Vegetarian than that of the non-vegetarian (p = .016). There were 6 non-vegetarian patients shift to vegetarian for 2 months. The pruritus score improved and IL-2 level decreased after change to vegetarian diet. CONCLUSION: We concluded that vegetarian diet might be associated with the amelioration of the uremic pruritus severity in hemodialysis patients.

BACKGROUND/PURPOSE: With an increasing geriatric population, the need for effective management of chronic conditions and medication use in the elderly is growing. Medication use in the elderly presents significant challenges due to changes in pharmacodynamic and pharmacokinetic profiles. We aimed to examine the impact of a collaborative physician-pharmacist medication therapy management (MTM) program for polypharmacy elderly patients. METHODS: Elderly patients with multiple chronic conditions on polypharmacy were enrolled in this prospective, randomized, and controlled study over 16 months of implementation. The intervention group consisted of patients randomized to a collaborative pharmacist-physician MTM program. They were monitored continuously by a clinical pharmacist, while patients in the control group received only usual care with follow-up assessment. Primary outcome was economic differences, measured in total medical expenditure. Secondary outcomes of clinical and humanistic effects were compared between the two groups. RESULTS: The total number of enrolled patients was 87 and 91 in the MTM and usual groups, respectively. The difference-in-difference estimate on medical expenditure during the 16-month implementation period was $3,758,373 New Taiwan Dollars ($127,015 US Dollars) less than the usually care group. Impact was also seen in humanistic outcomes while lipid profiles and mortality trended toward improvement. CONCLUSION: The pharmacist-physician collaborative MTM program for polypharmacy elderly had significant cost savings and improvement in humanistic measures, demonstrating the importance of clinical pharmacists and MTM programs for elderly patients in Taiwan. The results suggest the possibility of clinical benefits, but the study was not substantially powered to find a statistical difference.

AIM: Prolonged QT interval is related to changes of electrolytes in haemodialysis (HD) and is associated with all-cause mortality in HD patients. It is unknown if prolonged QT interval is associated with all-cause mortality in peritoneal dialysis (PD) patients as the electrolytes were relatively stable in PD. We therefore investigated the association of prolonged QT interval and all-cause mortality in chronic PD patients. METHODS: The QT intervals were measured in 2003 and all patients were followed to December 2012. A prolonged QT interval was defined as a QT interval > 450 ms. The association of prolonged QT interval with all-cause and cardiac-specific mortality was analyzed using Cox regression and Kaplan-Meier analysis. RESULTS: Of 306 patients, 196 (64%) patients had prolonged QT interval. The incidence density rate was 9.7 per 100 persons-years for all-cause mortality and 5.6 for cardiac specific mortality in patients with prolonged QT interval. Prolonged QT interval was associated with all-cause mortality with a hazard ratio (HR) of 1.59 (95% confidence interval (CI): 1.06-2.39, P = 0.03] and cardiac mortality (HR: 1.66, 95% CI: 1.00-2.78, P = 0.05) with adjustments for age, gender, diabetes, and vintage of dialysis. Longer QT interval (>500 ms, 450-500 ms, and < 450 ms) was significantly associated with a worse overall survival (P = 0.03, log-rank test) and cardiac mortality free survival (P = 0.05, log-rank test). CONCLUSIONS: Prolonged QT interval was associated with all-cause and cardiac mortality in patients on peritoneal dialysis. The association is independent of patient's age and diabetes.

BACKGROUND: Pruritus is a common and frustrating symptom in hemodialysis (HD) patients and 5-D itch scale is proposed as a reliable measurement of pruritus. However, information regarding 5-D itch scale categories is currently unavailable. We explored optimal cut-offs 5-D itching scale based on numerical rating scale (NRS) categories in HD patients. METHODS: Four hundred and nine HD patients in China Medical University Hospital in December 2014 were included and severity of pruritus was estimated using NRS and 5-D itch scale. The association of NRS and 5-D itch scale was analyzed by linear regression. The optimal cut-offs for 5-D itch scale based on NRS categories were generated. RESULTS: The average NRS was 3.4 ± 3.0 and the average 5-D itch scale was 10.9 ± 4.8. The 5-D score was strongly correlated with the NRS: r = 0.831 (p < 0.001). NRS = -2.31 + 0.52 × (5-D scale). The averages of 5-D scales were 6.4 ± 1.5, 9.6 ± 2.2, 13.1 ± 3.2, 15.7 ± 4.4, 19.5 ± 4.4 for no, mild, moderate, severe, and very severe pruritus based on categorized NRS. A 5-D itch scale categories were proposed, ≤ 8 for NRS = 0, 9-11 for mild pruritus, 12-17 for moderate pruritus, 18-21 for severe pruritus and ≥ 22 for very severe pruritus. CONCLUSIONS: Categories for the 5-D itch scale were proposed based on the measurements of pruritus severity in HD patients. This information provides a simple solution that enables transformation between the 5-D itch scale and the numerical rating scale.

BACKGROUND: Although the prescribing information for Venlafaxine extended release includes a discussion about possible increases in total cholesterol and triglycerides (TG) seen in healthier adult patients during premarketing clinical trials, no post-marketing studies or case reports, that discuss the effects of venlafaxine on TG in elderly patients with chronic kidney disease. CASE PRESENTATION: We report a 71 year-old male patient with end-stage renal disease on hemodialysis, with a history of coronary artery disease, mild hyperlipidemia, and hypertension. This patient twice demonstrated the severe rises in triglycerides while taking the antidepressant, i.e., venlafaxine, and discontinuing the long-term use of fenofirate. The adverse drug reaction sub-committee at the hospital rated the second event as a "probable reaction" using the Naranjo nomogram, accordingly. CONCLUSIONS: This case demonstrates the risk of changes in lipid profiles while taking venlafaxine and receiving on and off fenofibrate therapy in the older adult patient with chronic kidney disease and under hemodialysis. Regular monitoring for lipid changes after starting venlafaxine is strongly advised for patients with existing risk factors.

BACKGROUND: We hypothesize that autoantibodies are induced after the blood-brain barrier is damaged by stroke and the risk of bullous pemphigoid (BP) is increased after stroke. We assess the risk of BP after first-ever stroke in a nationwide population-based cohort of first-ever stroke patients. METHODS: We extracted data from the Longitudinal Health Insurance Database 2005 and identified patients with first-ever stroke as well as control patients matched for age, gender, and year of enrollment. The risk of BP in first-ever stroke patients in comparison with that in control patients was analyzed using Cox regression. RESULTS: Of 12,607 patients with first-ever stroke, 38 (0.3%) patients developed BP in a median of 3.5 years. In the control patients, 8 persons (0.06%) had BP in a median of 3.7 years. The crude hazard ratio (HR) of BP in first-ever stroke patients was 4.83 (95% CI 2.25-10.34, p < 0.001) compared to the control group. The adjusted HR was 4.20 (95% CI 1.94-9.08, p < 0.001) after adjustments for age, gender, hypertension, diabetes, dementia, epilepsy, Parkinson disease, furosemide, and neuroleptics for stroke patients. CONCLUSIONS: The risk of BP is increased in first-ever stroke patients in a nationwide population-based cohort and this association is independent of well-known confounders of BP.
