Is Kidney Stiffness Measured Using Elastography Influenced Mainly by Vascular Factors in Patients with Diabetic Kidney Disease?

Studies published so far using ultrasound-based elastography in the kidneys, lack to prove a clear relationship between kidney shear wave speed (KSWS) and renal disease progression. Taking into account that the kidney is a highly vascularized organ, the present study aims to find a relationship between KSWS and vascular factors (blood pressure [BP], arterial stiffness). Our study included 38 diabetic kidney disease patients (mean age 56.52 ± 16.12 years, 19 female, 19 male). KSWS, an indicator of renal stiffness, was measured using point Shear Wave Elastography (pSWE; Siemens Acuson S2000). In every patient, we recorded BP, and we measured aortic augmentation index (AAI) and brachial pulse wave velocity (PWV), using oscillometry. We found statistically significant indirect correlations of KSWS with indicators of arterial stiffness, such as PWV ( r = -.41, p = .036), and AAI ( r = -.37, p = .031). We found also an indirect correlation of KSWS with diastolic BP ( r = -.65, p = .02) and systolic BP ( r = -.54, p = .008). We found no correlation of KSWS with estimated glomerular filtration rate (eGFR), urinary albumin/creatinine ratio, stage of diabetic retinopathy, or glycated hemoglobin. Our study shows that high BP and the progression of arteriosclerosis (high PWV and AAI), leads to a decrease of renal stiffness. Thus, it seems that KSWS is influenced by renal blood flow, rather than other factors, such as albuminuria or chronic kidney disease stage.

Cholesterol Gallstones and Long-Term Use of Statins: Is Gut Microbiota Dysbiosis Bridging over Uncertainties?

A total of 300 research participants-200 consecutive patients diagnosed with dyslipidemia (100 statin (+), treated for at least five years, and 100 statin (-)) and 100 healthy controls-were included in this observational study. The aim of the study was to deliver insights into the relationship between the long-term use of statins for dyslipidemia and gallstone disease (GSD), as well as insights into the background particularities of the gut microbiota. All study participants underwent clinical examination, laboratory workups, stool microbiology/stool 16S r RNA, next-generation sequencing, and abdominal ultrasound/CT exams. Results: The research participants presented with similarities related to age, gender, and location. Patients displayed comparable heredity for GSs, metabolic issues, and related co-morbidities. Gut dysbiosis (DB) was present in 54% of the statin (-) patients vs. 35% of the statin (+) patients (p = 0.0070). GSs were present in 14% of patients in the statin (-) group vs. 5% of patients in the statin (+) group (p = 0.0304). Severe dysbiosis, with a significant reduction in biodiversity, an increase in LPS (+) bacteria, and a notable decrease in mucin-degrading bacteria, mucosa-protective bacteria, and butyrate-producing bacteria were observed in the statin (-) group. Strong positive correlations between GSD and diabetes/impaired glucose tolerance (r = 0.3368, p = 0.0006), obesity (r = 0.3923, p < 0.0001), nonalcoholic fatty liver disease (r = 0.3219, p = 0.0011), and DB (r = 0.7343, p < 0.0001), as well as significant negative correlations between GSD and alcohol use (r = -0.2305, p = 0.0211), were observed. The multiple regression equation demonstrated that only DB (95% CI: 0.3163 to 0.5670; p < 0.0001) and obesity (95% CI: 0.01431 to 0.2578; p = 0.0289) were independent risk factors predicting GSD in the group of patients treated with statins. Conclusion: The long-term use of statins in dyslipidemic patients was associated with a low risk of developing GSs. The gut microbiota associated with a long-term use of statins in dyslipidemic patients was characterized by a low risk of developing an imbalance of various functional bacteria and alterations in the metabolic microbiota. DB and obesity were found to be independent risk factors predicting GSD in statin (+) patients.

The Significance of Inflammation in Atrial Fibrillation.

AIM: The aim of the study was to assess the inflammatory status in individuals diagnosed with atrial fibrillation (Afi) and establish an association between this status and the clinicopathological features. MATERIAL AND METHODS: Our study was conducted retrospectively and initially involved 278 patients. However, after excluding 27 patients, we ultimately ended up with 167 patients who had an inflammatory status and 84 patients who did not have an inflammatory status. These patients were then analyzed. RESULTS: Patients who had inflammation showed higher values for the CHA2DS2-VASc and HAS-BLED scores (P= 0.0132 for CHA2DS2-VASc and P= 0.0024 for HAS-BLED). Also, it was observed that patients with associated inflammation exhibited an increase in both the volume and the area of the left atrium. Patients with hypertension had a higher prevalence of inflammation, with heart failure and with ischemic heart disease. It is worth noting that patients with atrial fibrillation and increased inflammatory status exhibited higher rates of stroke (22.75% vs 10.71% in patients without inflammation, odds ratio = 2.455, 95% confidence interval 1.161 to 5.425, p = 0.0253). CONCLUSIONS: Our research has demonstrated that patients diagnosed with atrial fibrillation and exhibiting a heightened inflammatory status also present association with other comorbidities, including hypertension, heart failure, ischemic heart disease, and stroke.

Hepatic Veno-Occlusive Disease and Colorectal Cancer: Expect the Unexpected.

Sinusoidal obstruction syndrome/veno-occlusive disease (SOS/VOD) is a rare liver vascular condition, potentially life-threatening, with clinical signs of portal hypertension, frequently reported in relation to bone marrow transplantation and possibly in non-transplantation-related chemotherapy. We report the case of a 65-year-old female patient who insidiously developed fatigue, mild tenderness of the right upper abdominal quadrant, hepato-splenomegaly and slight weight gain consecutive to ascites development, as well as persistent elevation of transaminases and mild thrombocytopenia. To note, she had a previous history of colorectal cancer (CRC) with liver metastases and several courses of chemotherapy. Abdominal duplex and elastography measurements made the diagnosis of cirrhosis improbable. A lot of lab work-ups were performed in order to rule out several diseases and conditions. Further, transjugular access was used to perform the measurement of the hepatic venous pressure gradient and liver biopsy that confirmed SOS/VOD. In late 2023, she was diagnosed with endometrial adenocarcinoma, requiring chemotherapy again. At present, the liver condition is stationary, but the prognosis is, however, uncertain. In conclusion, we presented the atypical case of a female patient who developed portal hypertension syndrome associated with the late onset of SOS/VOD, after 5-fluorouracil and oxaliplatin chemotherapy for CRC and liver metastases, subsequently diagnosed with endometrial adenocarcinoma, which posed many diagnostic and therapeutic challenges. Given the potentially bad outcome, an early diagnosis of SOS/VOD in patients receiving drugs of risk is important not only to stratify further risk, but also to initiate an appropriate therapy in order to improve the prognosis.

Factors Associated with Stroke in Atrial Fibrillation. A Retrospective Study.

AIM: The aim of our study was to retrospectively evaluate known factors such as CHA2DS2-VASc, but, also, new factors (such as left atrial remodeling), associated with the development of stroke in patients with atrial fibrillation (AFi). MATERIAL AND METHODS: We performed a retrospective study in which 251 patients with AFi were included. 47 patients had an ischemic stroke before the diagnosis of AFi, at the time of diagnosis or after AFi was diagnosed. The CHA2DS2-VASc score was analyzed for all patients together with other left atrial remodeling parameters. RESULTS: We observed that among the patients with ischemic stroke approximately 61.70% were over 72.5 years old compared to those without stroke who presented this age in a proportion of only 44.61% (OR=2.001, P=0.0367). The CHA2DS2-VASc score had the greatest statistical impact for stroke, as expected. Patients with a CHA2DS2-VASc score >4.5 presented stroke in a proportion of 87.23% compared to CHA2DS2-VASc <4.5 who had stroke only in a proportion of 12.77% (OR=11.51, P=<0.0001). Regarding left atrial remodeling parameters, low LA ejection fraction was associated with a high percentage of stroke among patients (61.70%) compared to those with LA EF>34.5% who had stroke only in a percentage of 38.30% (OR= 2.124, P=0.0238). CONCLUSIONS: Although the CHA2DS2-VASc score remains a good factor for predicting the association of AFi with ischemic stroke, echocardiographic parameters for the evaluation of the left atrium can be used as new risk factors for predicting the occurrence of ischemic stroke in patients with AFi.

Arterial Hypertension and Serum Uric Acid in Elderly- SEPHAR III Study. / Hipertensão Arterial e Ácido Úrico Sérico em Idosos - Estudo SEPHAR III.

BACKGROUND: Hyperuricemia is a frequent finding in patients with arterial hypertension, and there is increasing evidence that this entity is also a risk factor for cardiovascular disease. OBJECTIVE: In the context of an aging population, this study aims to evaluate serum uric acid levels and arterial hypertension prevalence and control in a subgroup of Romanian adults (>65 years), concerning the influence of age on these parameters. METHOD: The study sample consists of 1,920 adults included in SEPHAR III survey, of whom 447 were elderly patients (>65 years of age). During the two study visits, three blood pressure (BP) measurements were performed at 1-min intervals and serum uric acid levels, kidney function by estimated glomerular filtration rate, blood pressure, and intima media thickness measurements were conducted. Hypertension and controls were defined according to the current guidelines. Intima-media thickness evaluation was assessed by B-mode Doppler ultrasound evaluation. A significance level p < 0.05 was adopted for the statistical analysis. RESULTS: Adult patients had a significant lower serum uric acid levels, compared to elderly patients, regardless of glomerular filtration rate levels. Adult patients showed a significantly lower intima-media thickness levels, when compared to elderly patients. CONCLUSION: Similar to previous studies, in the present study, age represented one of the factors contributing to the increased level of serum uric acid. An increasing prevalence of arterial hypertension with age, together with a poor control of blood pressure, was also obtained.

FUNDAMENTO: A hiperuricemia é um achado frequente em pacientes com hipertensão arterial e há evidências cada vez maiores de que essa entidade seja também um fator de risco para doença cardiovascular. OBJETIVOS: No contexto da população em processo de envelhecimento, este estudo tem o objetivo de avaliar níveis de ácido úrico sérico e a prevalência e o controle da hipertensão arterial em um subgrupo da população de adultos romenos (>65 anos), em relação à influência da idade nesses parâmetros. MÉTODOS: A amostra do estudo consiste em 1920 adultos incluídos na pesquisa SEPHAR III, dos quais 447 eram pacientes idosos (>65 anos de idade). Durante as duas visitas do estudo, três aferições de pressão arterial (PA) foram realizadas em intervalos de 1 minuto, e foram realizadas medições de níveis de ácido úrico sérico, função renal por taxa de filtração glomerular, pressão arterial e espessura íntima-média. A hipertensão e os controles foram definidos de acordo com as diretrizes atuais. A avaliação da espessura íntima-média foi determinada pela avaliação por ultrassom Doppler modo B. Um nível de significância p < 0,05 foi adotado para a análise estatística. RESULTADOS: Pacientes adultos tinham níveis de ácido úrico sérico significativamente mais baixos, se comparados a pacientes idosos, independentemente dos níveis de taxa de filtração glomerular. Pacientes adultos tinham níveis de espessura íntima-média, comparados a pacientes idosos. CONCLUSÃO: De forma semelhante às pesquisas anteriores, neste estudo, a idade representou um dos fatores contribuintes ao nível aumentado de ácido úrico sérico. Também foi obtido um aumento da prevalência da hipertensão arterial com a idade, com um mau controle da pressão arterial.

Serum uric acid and arterial hypertension-Data from Sephar III survey.

OBJECTIVES: This paper aims to evaluate the association between serum uric acid (SUA) levels, arterial hypertension (HT) prevalence, blood pressure values control, kidney function and intima media thickness (IMT), as a surrogate marker of early atherosclerosis, in a representative group of Romanian adult population. MATERIALS AND METHODS: The study sample consists in 1920 adults included in SEPHAR III (Study for the Evaluation of Prevalence of Hypertension and cArdiovascular Risk in Romania) survey (mean age 48.63 years, 52.76% females) collecting data for SUA levels, blood pressure (BP) measurements, kidney function by estimated glomerular filtration rate (eGFR) and carotid IMT. SUA levels between 2,40-5,70mg/dl in females and 3,40-7,00mg/dl in males respectively were considered normal. HT and HT control were defined according to the current guidelines. IMT evaluation was assessed by B-mode Doppler ultrasound evaluation. RESULTS: Hypertensive subjects had significantly higher values of SUA compared with normotensive subjects, hypertensive patients were 1.713 times more likely to have higher values of SUA. Among treated hypertensive patients, those without optimal BP control had significantly higher SUA levels compared with those with optimal BP control, the presence of hyperuricemia increasing the odds of suboptimal BP control by 1.023. Hyperuricemic subjects had significantly lower eGFR values compared with normouricemic ones, on an average with 14.28ml/min/1.73m2 by Modification of Diet in Renal Disease formula (MDRD) and with 16.64ml/min/1.73m2 by Chronic Kidney Disease Epidemiology Collaboration formula (CKD-EPI), with an indirect association between SUA levels and eGFR values (rs = -0.319 / -0.347), independent of age. IMT values recorded in hyperuricemic subjects were significantly increased, on an average with 0.08mm, compared with normouricemic subjects, with a direct association between SUA levels and IMT values (rs = 0.263), independent of BP values. CONCLUSION: The results of our study offers support that increased SUA levels are associated with arterial hypertension and with suboptimal BP control in treated hypertensive subjects. The decline in kidney function, independent of age, and also increased IMT values as a marker of atherosclerosis, were also correlated with elevated SUA values. Hyperuricemia screening may have a role in identifying patients at risk of developing HT and lowering SUA levels may improve not only BP control in treated HT patients but also decrease total cardiovascular mortality by slowing the progression of atherosclerosis and renal failure in hypertensive patients.

The value of contrast-enhanced ultrasound in the characterization of vascular pattern of solid pancreatic lesions.

UNLABELLED: The AIM of our study was to evaluate the accuracy of CEUS in the characterization of pancreatic solid lesions, considering cross sectional imaging techniques (CE-CT/MRI) as the "gold standard" methods. MATERIAL AND METHODS: We performed a retrospective, monocentric study that included 91 solid pancreatic lesions which were evaluated by CEUS and by a second-line contrast imaging technique (CT or MRI), considered as the reference method. RESULTS: The rate of a conclusive diagnosis based on a typical enhancement pattern was 94% (78/83 cases). In 72 cases out of 83 (86.7%) there was a perfect concordance between CEUS and the "gold-standard" imaging method (CE-CT/MRI). In our study, 88% (73/83) of the pancreatic lesions were categorized as malignant due to their typical wash-out aspect in the late phase. The overall accuracy of CEUS for the differential diagnosis of solid pancreatic tumors was approximately 81%. The accuracy of CEUS for the diagnosis of hypoenhancing pancreatic tumors was approximately 89.1%; while for the diagnosis of hyperenhancing pancreatic tumors it was approximately 72.8%. CONCLUSION: CEUS allows the differentiation between hypo- vs. hyperenhancing pancreatic solid lesions, with a considerable diagnostic accuracy, a fundamental step in the precise diagnosis of pancreatic tumors.

Contrast enhanced ultrasound in the pathology of the pancreas - a monocentric experience.

UNLABELLED: The AIM: of this study was to summarize the spectrum of pancreatic pathology assessed by contrast enhanced ultrasound (CEUS) in a single Gastroenterology Center and to emphasize its accuracy in assessing two of the most important pancreatic lesions: solid tumors and necrotic lesions in acute pancreatitis. MATERIAL AND METHODS: Our retrospective study included 197 patients with pancreatic lesions (de novo pancreatic masses; acute, severe pancreatitis; other pathologies) evaluated by CEUS from October 2009 to May 2013, in which a reference method (contrast CT/MRI) was available. RESULTS: A conclusive diagnosis was established according to the EFSUMB Guidelines in 87.8% of the 197 cases. In 87.3% cases there was a perfect concordance between CEUS and the reference method (contrast CT/MRI). 95 examinations were made for pancreatic solid masses: 41.1% (39) were hypoenhanced, 34.7% (33) were hyperenhanced, and 20% (19) were isoenhancing - chronic pancreatitis and autoimmune pancreatitis - while in 4.2% (4) cases CEUS was inconclusive. 60 examinations were made in severe acute pancreatitis and in 50% (30) cases pancreatic necrosis was diagnosed. 42 examinations were performed for other lesions: 64.2% (27) pancreatic pseudocysts, 11.9% (5) cystic tumors, 23.8% (10) other pathologies (abscesses, fibrosis, etc). CEUS accuracy for solid tumors was 92.9%. For necrotic lesions the accuracy was 97.4%. CONCLUSIONS: CEUS has turned to be a good method for the characterization of different pancreatic pathologies and for evaluating acute pancreatitis. CEUS was conclusive in 90% cases and it should be considered as a first line imaging method in clinical practice.

Is There any Difference Between the Glomerular Filtration Rate of Patients With Chronic Hepatitis B and C and Patients With Cirrhosis?

BACKGROUND: Renal dysfunction is a major determinant of the Model of End-stage Liver Disease (MELD) score. The implementation of the MELD score has shifted allocation of livers to patients with renal dysfunction. OBJECTIVES: The aim of our study was the assessment of estimated Glomerular Filtration Rate (eGFR) by the Modification of Diet in Renal Disease 4 (MDRD4) method in patients with HBV chronic hepatitis, HCV chronic hepatitis, and cirrhosis (CH) caused by these viruses to detect any differences in renal function among these diseases. PATIENTS AND METHODS: We performed a cross-sectional analysis of all consecutive patients with HBV chronic hepatitis, HCV chronic hepatitis, and cirrhosis caused by these viruses hospitalized during a 4 year period in the Gastroenterology and Hepatology department of the Emergency County Hospital Timisoara, Romania. The eGFR was assessed by the MDRD4 method. Statistical analysis (unpaired t-test, ANOVA, Chi Square test) was performed using OpenEpi 2.3.1. RESULTS: HBV chronic hepatitis, HCV chronic hepatitis, and cirrhosis secondary to these viruses were associated with a reduction of the GFR. The eGFR was higher in patients with HBV chronic hepatitis than in patients with HCV chronic hepatitis (P < 0.001). Patients with cirrhosis secondary to HBV infection had a higher eGFR than patients with cirrhosis secondary to HCV (P = 0.01). The eGFR of patients with HCV chronic hepatitis was higher than the eGFR of patients with cirrhosis due to this virus (P < 0.001). CONCLUSIONS: Functional renal impairment in diseases caused by HCV was more important than in diseases caused by HBV. The eGFR was statistically lower in cirrhosis secondary to HCV than in HCV chronic hepatitis.

Asymptomatic urinary anomalies, hematuria and proteinuria, in patients with inflammatory bowel disease. Preliminary study.

The study assesses the presence of asymptomatic urinary anomalies in patients with inflammatory bowel disease. Asymptomatic urinary anomalies are mainly due to glomerular nephritis, they being one of the forms of its manifestation, together with chronic nephrotic and nephritic syndromes. We identified urinary anomalies in 18 patients (20%) with bowel inflammatory disease that consisted of haematuria in 8 (9%) patients, isolated proteinuria in 5 (6%) patients and haematuria associated with proteinuria in 5 (6%) patients. Asymptomatic urinary anomalies were more frequent in patients with the Crohn disease than in those with ulcerative colitis. We identified RFG under 60ml/min in 4 patients with asymptomatic urinary anomalies. It is very easy to evaluate asymptomatic urinary anomalies with dipstick. This method is also required in current practice for patients with urinary anomalies for identifying the glomerular disease that might have caused them. One must take into consideration differential diagnosis with other diseases that can manifest themselves with proteinuria or isolated proteinuria. One must also take into account the fact that urinary anomalies may also be related to administration of 5-aminosalicylates.
