Renal pseudohypoaldosteronism type 1-an adult case series including a novel gene variant.

Renal pseudohypoaldosteronism type 1 (PHA1) is a rare disease affecting infants. Symptoms are failure to thrive, vomiting, and weight loss. It is caused by gene variants in NR3C2 by which the mineralocorticoid receptor is dysfunctional, and patients develop hyponatremia, elevated plasma aldosterone, and renin but have normal blood pressure. Little is known about PHA1 in adults. We present four adults with PHA1, their clinical, biochemistry, and genetic data. Clinical and biochemical data were collected from the medical files and clinical examination of the participants. Genetic testing was performed. Two adult dizygotic twins and their mother, as well as an adult man were included. One of the sisters and the man had had severe hyponatremia and been admitted several times as young infants, treated with sodium chloride and fludrocortisone. All had as adults elevated plasma aldosterone and normal sodium. The females now had normal plasma renin, but it was increased in the male. A novel genetic variant in NR3C2 was found in the twins and their mother (c.1816T>C, p.(Cys606Arg)). All had normal blood pressure and were asymptomatic. In adulthood, PHA1 seems to be asymptomatic and long-term consequences favorable.

Safety Evaluation of Amla extract by Acute and Sub-chronic exposure in rats

The current study sought to assess the safety of amla extract (Tri-Low®) in rats by acute and repeated dose (90-days) administration as per the OECD (Organisation for Economic Co-operation and Development) guidelines 423 and 408, respectively. In acute toxicity, amla extract was given to overnight starved rats as single dose (2000 mg/kg). Daily clinical symptoms of abnormality/mortality were studied by a veterinarian for 2 weeks period. In the repeated dose study (90 days; sub chronic) amla extract was orally given to rats at low (100mg/kg), medium (500 mg/kg) and high (1000 mg/kg) dose for 3 months. Hematological and biochemical markers were measured after 90 days of feeding. The histopathology of all main organs was also investigated. No death or clinical abnormalities were found in the acute toxicity investigation at 2000 mg/kg; thus, LD50 in rats was recorded as >2000mg/kg (GHS category 5). In the sub-chronic study, there were no visible adverse effects at any dose after repeated feeding of amla extract for 90 days. The hematological and biochemistry data of all the rats were in normal range and there was no statistically significant difference between control and amla extract fed rats (p>0.05). The histology of all the organs was normal for all the groups. The NOAEL (No-Observed-Adverse-Effect-Level) for amla extract in this investigation was established as 1000mg/kg daily. It can be inferred that Tri-Low® is safe to use as a daily food supplement for the management of cardiac and metabolic health.

Pharmacokinetics of intramuscular L-carvone in sheep.

To measure and model concentrations of the analgesic L-carvone, a natural component of spearmint, over time when administered IM to sheep and to characterize L-carvone's effects on CBCs and clinical biochemistry panels. L-carvone formulated as a 50% solution (v/v) in ethanol and propylene glycol was administered at 71.6 mg/kg IM, split between each semitendinosus muscle in 6 sheep. Venous blood was sampled over 24 hours, and plasma was separated by centrifugation. Additional blood was collected for CBC and serum biochemical analysis, and tissues were sampled after euthanasia. L-carvone concentrations in plasma and tissue homogenates were measured using HPLC-MS-MS. Plasma pharmacokinetic data were described using a nonlinear mixed effects model. Complete blood count and biochemistry data were compared to baseline values using repeated-measures ANOVA and Holm-Šidák tests (P < .05). Maximum plasma concentrations ranged from 0.28 to 1.93 µg/mL and occurred within 9 to 15 minutes after injection. Pharmacokinetics were best described using 2 compartments. Elimination half-life was 33.7 minutes and 390.2 minutes in the central and peripheral compartments, respectively. Mild increases in neutrophil count and significant increases in creatinine kinase and aspartate aminotransferase were associated with injection site myonecrosis. No physical examination, behavioral, or other clinically significant laboratory changes were noted. Intramuscular L-carvone exhibits rapid time to peak concentration, relatively slow plasma elimination, and low tissue concentrations after 24 hours. L-carvone exhibits a favorable pharmacokinetic profile for an analgesic drug. A new L-carvone formulation or administration route is needed to reduce inflammation and necrosis at the injection site.

Analysis of New Hemogram Markers in Patients Presenting to the Emergency Department with Epileptic Seizures

Objective: We aimed to analyze the diagnostic value of new potential hemogram biomarkers in patients presenting to the emergency department with epileptic seizures. Materials and Methods: Patients presenting with epileptic seizures to a tertiary hospital's emergency department between January 1, 2023, and January 31, 2024, were retrospectively reviewed. The patients were categorized into Group A (seizure patients) and Group B (healthy volunteers). Hemogram and biochemistry data from routine blood tests were examined. To predict seizure status, ROC analysis was performed to evaluate NLR, PLR and PNR. The area under the curve and cutoff values were calculated for each marker. Results: Our study examined two groups: seizure patients and the control group. The mean age of the seizure group was 50.31±1.83 years, and the mean age of the control group was 49.58±1.96 years (p&gt;0.05). In the seizure group (n=116), 55.8% were male and 44.2% were female, whereas in the control group (n=104), 57.8% were male and 42.2% were female (p&gt;0.05). WBC, neutrophil count, NLR, and PLR values were significantly higher in seizure patients compared to the control group (p

Screening for Fabry disease in patients with left ventricular hypertrophy in China: A multicentre and prospective study.

Left ventricular hypertrophy (LVH) is frequently detected via echocardiography in individuals with Fabry disease (FD), sometimes leading to confusion with hypertrophic cardiomyopathy (HCM) of other aetiologies. Considering this diagnosis challenge, FD should be included in the list of differential diagnosis for patients presenting with LVH. To address this concern, we conducted a prospective screening study in China, using dried blood spot (DBS) testing, to evaluate patients with unexplained LVH. Our study was designed as a nationwide, multicentre prospective investigation. A total of 1015 patients from 55 different centres who were diagnosed with LVH by echocardiography were screened in the study from September 2022 to December 2023. Demographic information, biochemistry data, echocardiography parameters and clinical observations were meticulously collected from all participants. The DBS method was used to assess α-galactosidase A (α-Gal A) activity in males and both α-Gal A and globotriaosylsphingosine (lyso-Gb3) levels in females. The final screening population included 906 patients (589 males, 65%) with LVH, characterized by a mean maximal myocardial thickness of 14.8±4.6mm and an average age of 56.9±17.2years. In total, 43 patients (38 males, 5 females) exhibited low α-Gal A activity measurement (<2.2μmol/L), while 21 patients (10 males, 11 females) presented low α-Gal A activity or elevated lyso-Gb3 levels (>1.1ng/mL). Among these patients, eight individuals (7 males and 1 female) were genetically confirmed to harbour pathogenic GLA mutations, resulting in a total prevalence of 0.88%. Compared with patients without FD, patients with FD tended to have proteinuria (75% vs. 21.2%, P=0.001), family history of HCM (37.5% vs. 2.3%, P<0.01) and neuropathic pain (37.5% vs. 4.4%, P<0.01) but lower systolic blood pressure (118.5±12.5 vs. 143.3±29.3mmHg, P=0.017). Five mutations were previously recognized as associated with FD while the remaining two, p.Asp313Val (c.938A>T) and c.547+3A>G, were deemed potentially pathogenic. Subsequent familial validation post-diagnosis identified an additional 14 confirmed cases. This pioneering screening study for FD among Chinese patients with unexplained LVH using DBS measurement, revealed an FD detection rate of 0.88%. Our findings confirmed that the combined measurement of lyso-Gb3 and α-Gal A activity is beneficial for primary screening of FD in patients with LVH. Given the availability of efficacious therapies and the value of cascade screening in extended families, early detection of FD in LVH patients is clinically important.

Hypertension status and its risk factors in highlanders living in Ganzi Tibetan Plateau: a cross-sectional study

BackgroundThe updated status of hypertension and its risk factors are poorly evaluated in Tibetan highland areas. We initiated a large-scale cross-sectional survey to provide updated status of hypertension and its risk factors (especially salt intake) in the Ganzi Tibetan Plateau, China.MethodsStratified multistage random sampling was performed to obtain a representative sample of 4,036 adult residents from 4 counties in the Ganzi Tibetan area. The whole survey population was used to present the epidemiology and risk factors of hypertension. The participants with blood and urine biochemistry data were used to analyze the relationship between salt intake parameters and hypertension.ResultsStratified multistage random sampling was performed to obtain a representative sample of 4,036 adult residents. The overall prevalence rate of hypertension was 33.5% (the age-adjusted prevalence rate was 28.9%). A total of 50.9% of the hypertensive patients knew their conditions; 30.1% of them received antihypertensive treatment; and 11.2% of them had their blood pressure controlled. Age, male sex, living altitude ≥ 3500 m, overweight and abdominal obesity were positively correlated with hypertension. In addition, the adjusted odds ratio (OR) for hypertension was 1.33 (95% CI: 1.01–1.74) for drinking tea with salt, and 1.51 (95% CI: 1.32–1.72) for per SD increase in the estimation of 24-hour urinary sodium excretion (e24hUSE). Furthermore, per 100mmol/day increase in e24hUSE was associated with elevation of blood pressure (+ 10.16, 95% CI: 8.45–11.87 mmHg for SBP; +3.83, 95% CI: 2.74–4.93 mmHg for DBP) in this population.ConclusionsOur survey suggests a heavy disease burden of hypertension in the Ganzi Tibetan Plateau. Age, male sex, altitude of residence ≥ 3500 m, overweight, abdominal obesity, and excessive salt intake (shown as drinking tea with adding salt and a higher level of e24hUSE) all increased the risk of hypertension in this highland area.

Pre-treatment with tocilizumab reduces lipopolysaccharide-induced acute lung injury in biliary cirrhotic rats

Infection-related lipopolysaccharide (LPS) release causes cytokine storm and acute lung injury. Emerging data show that the interleukin 6 (IL-6) inhibitor tocilizumab can improve lung damage in patients with sepsis. This study aimed to investigate the therapeutic effect of tocilizumab on acute lung injury in cirrhotic rats. Biliary cirrhosis was induced in Sprague-Dawley rats with common bile duct ligation (BDL). Sham-operated rats served as surgical controls. Tocilizumab was administered on post-operative day 21, and LPS was injected intraperitoneally on day 29. Three hours after LPS injection, hemodynamic parameters, biochemistry data, and arterial blood gas analysis were evaluated, along with measurements of IL-6 and tumor necrosis factor-α (TNF-α). Liver and lung histology was examined, and protein levels were analyzed. LPS administration reduced portal pressure, portal venous flow and cardiac index in the BDL rats. In addition, LPS administration induced acute lung injury, hypoxia and elevated TNF-α and IL-6 levels. Pre-treatment with tocilizumab did not affect hemodynamic and biochemistry data, but it ameliorated lung injury and decreased TNF-α, IL-6, and CD68-positive macrophage infiltration. Moreover, tocilizumab administration improved hypoxia and gas exchange in the BDL rats, and downregulated hepatic and pulmonary inflammatory protein expression. In conclusion, LPS administration induced acute lung injury in biliary cirrhotic rats. Pre-treatment with tocilizumab reduces lung damage and hypoxia, possibly by downregulating inflammatory proteins and reducing IL-6, TNF-α and CD68-positive macrophage recruitment in the lung.

RELATIONSHIP BETWEEN ELECTROCARDIOGRAPHY AND ELECTROLYTES BEFORE AND AFTER DIALYSIS IN HEMODIALYSIS PATIENTS

Background: Cardiovascular events are the most important cause of mortality in hemodialysis patients. Rapid volume changes and electrolyte shifts during dialysis lead to arrhythmias. Objective: We aimed to determine whether there is a relationship between electrocardiographic (ECG) wave and interval changes and electrolyte levels before and after hemodialysis in dialysis patients. Materials and Method: A total of 112 patients undergoing hemodialysis three times a week for four hours for more than six months were included in the study. Before and after hemodialysis, 12-lead ECG, weight, arterial blood pressure, hemogram, biochemistry, and demographic data were recorded. Waves and intervals were calculated from the 12-lead ECG taken before and immediately after dialysis, and the relationship with serum electrolyte levels was evaluated. P

An Alternative Non-Invasive Screening Model for Liver Fibrosis among US Adults at Risk of MASLD.

Background and Aims: Screening for liver fibrosis presents a clinical challenge. This study aimed to explore a useful alternative method for assessing fibrosis risk among US adults at risk of metabolic dysfunction-associated steatotic liver disease (MASLD). Methods: A liver stiffness score (LSS) model was proposed and tested using data from 3976 participants at possible risk of MASLD, obtained from the US National Health and Nutrition Examination Survey (NHANES). Results: The LSS model was developed using liver stiffness measurements, blood biochemistry, and body measurement data from 2414 NHANES participants at risk of MASLD, sampled between 2017 and 2020: LSS = exp(0.007035 × bodyweightkg - 0.1061 × raceblack1,0 + 0.183221 × diabetes1,0 + 0.008539 × ASTIU/L - 0.0018 × plateletcount1000cell/UL - 0.21011 × albuming/dL + 2.259087). The probability (P) of having fibrosis F3 + F4 is calculated as follows: P = 0.0091 × LSS2 - 0.0791 × LSS + 0.1933. The developed LSS model was tested on 1562 at-risk participants from the 2017-2018 cycle. The results showed that the LSS model achieved AUROC values of 0.79 and 0.78 for diagnosing cirrhosis (F4) and advanced fibrosis (F3 + F4) in the US population, respectively. It outperformed existing models such as NFS, FIB-4, SAFE, and FIB-3. For screening F3 + F4 fibrosis, the LSS model's top decile outperformed the NFS and FIB-4 models by 37.7% and 42.6%, respectively. Additionally, it showed superior performance compared to the waist circumference classification method by 29.5%. Conclusions: derived from an ethnically diverse population dataset, the LSS screening model, along with its probability equation, may offer clinicians a valuable alternative method for assessing the risk of liver fibrosis in the at-risk adult population.

Can inflammatory markers such as lymphocyte to C-reactive protein ratio and hemoglobin, albumin, lymphocyte, and platelet score predict complications after loop ileostomy closure?

Aim: This study aims to investigate whether inflammatory biochemical markers such as hemoglobin, albumin, lymphocyte, platelet scores (HALP), and lymphocyte-C-reactive protein ratio (LCR) can predict complications after ileostomy closure. Methods: Eighty-five patients who underwent loop ileostomy closure were included in this retrospective study. Alongside the patient’s demographic data, surgical data, histopathology results, and biochemistry data were recorded. Complications that occurred within the first 30 days after surgery were evaluated using the Clavien-Dindo classification. Inflammation markers such as HALP and LCR were obtained using biochemical parameters. Results: The rate of mild complications (Clavien-Dindo I and II) was 27%, while the rate of severe complications (Clavien-Dindo III and IV) was 12.94%. A statistically significant correlation was found between the development of early complications and levels of albumin, lymphocyte, neutrophil, and C-reactive protein (CRP) (p

Does COVID-19 infection alter serum biochemical and hematological biomarkers in deceased dementia patients?

Abstract Objectives The elderly population is categorized as a risk group for COVID-19 infection, and dementia is the primary cause of disability in elderly individuals and affects 70 % of the elderly population. In this study, we evaluated the blood and serum biomarkers of deceased dementia patients infected by COVID-19 compared to the survived dementia and non-dementia patients. Methods Laboratory biomarkers of 11 dementia patients infected by COVID-19 have been used for this study. The five patients’ serum biochemistry and blood data were compared with the six patients who died because of COVID-19. Additionally, data from nine patients aged 85–96 infected with COVID-19 without dementia have been used to compare the difference between dementia and non-dementia individuals. Results D-dimer, C-reactive protein (CRP), glucose, blood urea nitrogen (BUN), alanine transaminase (ALT), aspartate aminotransferase (AST), troponin, procalcitonin, red cell distribution width (RDW), white blood cell (WBC), neutrophil (NEU) and %NEU levels significantly increased in the deceased dementia patients compared to the survived and non-dementia individuals. Calcium (Ca), hematocrit (HCT), red blood cells (RBC), lymphocyte (%LYM), monocyte %MONO, and basophil (%BASO) levels significantly decreased in the deceased dementia patients compared to the survived and non-dementia individuals infected by COVID-19. Conclusions Serum biochemistry and hematological biomarkers, including D-dimer, CRP, glucose, ALT, AST, BUN, troponin, procalcitonin, RDW, RBC, WBC, NEU, %NEU, Ca, HCT, %LYM, %MONO, and %BASO were significantly altered in deceased dementia patients infected by COVID-19 compared to the survived individuals.

Gut Microbiota in Patients with Prediabetes.

Prediabetes is characterized by abnormal glycemic levels below the type 2 diabetes threshold, and effective control of blood glucose may prevent the progression to type 2 diabetes. While the association between the gut microbiota, glucose metabolism, and insulin resistance in diabetic patients has been established in previous studies, there is a lack of research regarding these aspects in prediabetic patients in Asia. We aim to investigate the composition of the gut microbiota in prediabetic patients and their differences compared to healthy individuals. In total, 57 prediabetic patients and 60 healthy adult individuals aged 18 to 65 years old were included in this study. Biochemistry data, fecal samples, and 3 days of food records were collected. Deoxyribonucleic acid extraction and next-generation sequencing via 16S ribosomal ribonucleic acid metagenomic sequencing were conducted to analyze the relationship between the gut microbiota and dietary habits. Prediabetic patients showed a lower microbial diversity than healthy individuals, with 9 bacterial genera being less abundant and 14 others more abundant. Prediabetic patients who consumed a low-carbohydrate (LC) diet exhibited higher diversity in the gut microbiota than those who consumed a high-carbohydrate diet. A higher abundance of Coprococcus was observed in the prediabetic patients on an LC diet. Compared to healthy individuals, the gut microbiota of prediabetic patients was significantly different, and adopting an LC diet with high dietary fiber consumption may positively impact the gut microbiota. Future studies should aim to understand the relationship between the gut microbiota and glycemic control in the Asian population.

Prevalence of canine renal crest hyperattenuation in precontrast computed tomography.

Normal canine kidneys are relatively homogeneous soft tissue attenuating structures on nonenhanced CT images. However, visible differences in attenuation between the renal crest and medulla are occasionally observed. This finding and its potential clinical implications have not been previously investigated. This study aimed to estimate the prevalence of renal crest hyperattenuation (RCH) and investigate possible associations with signalment and laboratory parameters. Abdominal CT studies from 100 dogs, with biochemistry and urinalysis data obtained within 48h before the CT acquisition, were categorized by two radiologists into those with and without visible RCH. The attenuation in Hounsfield units (HU) of the renal crest and renal medulla were measured. Signalment, biochemical, and urinalysis data were analyzed for associations with RCH. Correlation coefficients were calculated for measured HU and associated continuous parameters. Prevalence of RCH was 42.42% (42/99 dogs, 95% CI, 33-52%). Urinary specific gravity (USG) was significantly different between dogs with and without RCH (P=.034). Weak positive correlations were identified between left and right renal crest attenuation and USG (r=0.233 and 0.253, respectively; P=.05). Renal crest hyperattenuation is a common finding in dogs undergoing abdominal CT. Although the correlation between the USG and renal crest HU is weak, the dogs with RCH have significantly higher USG. Renal crest hyperattenuation might, therefore, not be associated with renal insufficiency. No other specific associations of RCH were identified with parameters typically altered in a variety of diseases. Further investigation may be warranted for its relevance to specific diseases or if it indeed represents a physiological variant.

Clinical characteristics, imaging features, and outcomes of primary hepatic angiosarcoma: A single‐center study and literature review

AbstractPrimary hepatic angiosarcoma (PHA) accounts for 0.5% to 2% of all primary hepatic malignancies, and histopathology findings are required to diagnose PHA accurately. This study investigated 12 patients with PHA at a single medical center in southern Taiwan. We analyzed the clinical characteristics, imaging features, histopathology findings, and survival outcomes of patients with PHA. Of the 12 patients, abdominal pain and fullness were the most common symptoms, and their liver biochemistry data and tumor markers were mostly within the normal limits. The liver tumors tended to present as multifocal or diffuse nodules with bilobar involvement. The median overall survival (OS) of the 12 patients after diagnosis was 9 months. Improved OS was observed in the surgery group compared with the nonsurgery group (15 vs. 2 months, p = .003). The median OS of patients in the surgery ± systemic therapy group was superior to that of patients in the systemic therapy group and in the no‐therapy groups (15 vs. 5 vs. 2 months, respectively; p = .012). Complete surgical resection remains the optimal treatment choice, and combined surgery and systemic therapy seem beneficial but require further investigation.

Ezetimibe treatment reduces oxidized low-density lipoprotein in biliary cirrhotic rats.

In liver cirrhosis, chronic inflammation is associated with an increase in oxidative stress, and subsequently an increase in the concentration of oxidized low-density lipoprotein (ox-LDL). Ezetimibe is a lipid-lowering agent with anti-inflammation and anti-oxidative stress activities. This study aimed to investigate the effect of ezetimibe treatment on ox-LDL in cirrhotic rats. Biliary cirrhosis was induced in Sprague-Dawley rats with common bile duct ligation (BDL). Sham-operated rats served as surgical controls. Ezetimibe (10 mg/kg/d) or vehicle was administered in the sham-operated or BDL rats for 4 weeks, after which hemodynamic parameters, biochemistry data, and oxidative stress were evaluated. Plasma and intrahepatic ox-LDL levels were also examined, and hepatic proteins were analyzed to explore the mechanism of ezetimibe treatment. The BDL rats had typical features of cirrhosis including jaundice, impaired liver function, hyperlipidemia, and elevated ox-LDL levels compared to the sham-operated rats. Ezetimibe treatment did not affect hemodynamics, liver biochemistry, or plasma lipid levels. However, it significantly reduced oxidative stress, plasma levels of ox-LDL, and tumor necrosis factor α. In addition, ezetimibe upregulated the hepatic protein expression of an ox-LDL scavenger (lectin-like ox-LDL rececptor-1), which resulted in reductions in intrahepatic ox-LDL and fat accumulation in the BDL rats. Nevertheless, ezetimibe treatment did not ameliorate hepatic inflammation or liver fibrosis. Ezetimibe reduced plasma and intrahepatic ox-LDL levels in the cirrhotic rats. Furthermore, it ameliorated intrahepatic fat accumulation and oxidative stress. However, ezetimibe did not alleviate hepatic fibrosis or inflammation in the biliary cirrhotic rats.

Exploring multifaceted factors in chronic kidney disease risk: A comprehensive analysis of biochemistry, lifestyle, and inflammation in elderly Chinese individuals.

This letter praises a recent article in the World Journal of Clinical Cases (Roles of biochemistry data, lifestyle, and inflammation in identifying abnormal renal function in old Chinese), examining factors affecting abnormal renal function in elderly Chinese using advanced machine learning. It highlights the importance of uric acid, age, hemoglobin, body mass index, sport hours, and systolic blood pressure. The study's holistic approach, integrating lifestyle and inflammation, offers a nuanced understanding of chronic kidney disease risk factors. The letter suggests exploring mechanistic pathways of hyperuricemia, the link between anemia and renal function, and the connection between body mass index and estimated glomerular filtration rate. It advocates investigating physical activity's impact on renal health and the independent effects of blood pressure. The study significantly contributes to chronic kidney disease understanding, proposing avenues for further exploration and interventions. Commendations are extended to the authors and the journal.

Risk Factors for Urinary Tract Infections in Children with Hematuria in the Emergency Department.

Hematuria is a worrisome symptom in children and is sometimes associated with urinary tract infections (UTIs). This study aimed to identify useful clinical factors that can predict UTIs in hematuria patients without pyuria in the pediatric emergency department (ED). We retrospectively recruited patients with hematuria from the pediatric ED. Clinical symptoms, urine biochemistry and microscopic examination results, and blood laboratory tests were analyzed to identify the predictors of UTIs. Patients were divided into the verbal group (age ≥ 2 years) and non-verbal group (age < 2 years) for identifying predictors of UTIs. Causes of hematuria were also investigated. A total of 161 patients with hematuria without pyuria were evaluated. Among symptoms, dysuria was significantly correlated with UTIs. Regarding urine biochemistry data, urine esterase and urine protein > 30 mg/dl were found to be significant parameters for predicting UTIs, while urine esterase and urine nitrite showed significant differences in children with age < 2 years. In the urine microscopic examinations, urine red blood cells (RBC) > 373/µL in children aged ≥ 2 years and urine RBC > 8/µL in children aged < 2 years were associated with UTIs. In addition, UTIs and urinary tract stones were found to be the top two causes of hematuria. Dysuria, urine esterase, urine nitrite, and urine protein may be useful parameters for predicting UTIs in pediatric patients with hematuria but no pyuria in the ED. In addition, a UTI was the most commonly identified etiology of hematuria without pyuria, followed by urinary tract stones.
