Background: Procalcitonin (PCT) has emerged as a marker of infection and it could be useful for detection of systemic bacterial infections in patients with end-stage renal disease (ESRD) undergoing hemodialysis (HD). The aim of this study was to assess the influence of HD membrane permeability to PCT serum levels in noninfected HD patients on maintenance HD. Methods: In a prospective comparative study, we measured PCT serum levels and C reactive protein (CRP) before and after HD in 36 sessions (18 sessions of HD with low-flux = Group L; and 18 sessions with high flux membranes = Group H), in 18 chronic HD patients without history of infection. Results: Sessions of HD by high-flux membranes (Group H) displayed median PCT values that were significantly decreased after dialysis (0.21 ng/mL [0.13-0.41] vs. 0.18 ng/mL [0.10-0.24], p <0.001) but median PCT significantly increased after HD sessions by low-flux membranes (Group L) (0.21 ng/mL [0.14-0.33] vs. 0.25 ng/mL [0.14-0.36]; p = 0.008). CRP values were significantly increased after HD in both groups. CRP correlated with PCT values only in group H before HD (r = 0.49; p = 0.36). Conclusions: PCT represents a useful diagnostic marker for systemic bacterial infection. However, there is a need for specific reference ranges to be developed in patients with renal failure undergoing HD; also, PCT serum levels must be interpreted according to the HD membrane permeability.

Increased serum levels of uric acid have been associated with the onset and development of chronic kidney disease (CKD), cardiovascular disease, and mortality, through several molecular pathogenetic mechanisms, such as inflammation and oxidative stress. Oxidative stress is present even in the early stages of CKD, progresses parallelly with the deterioration of kidney function, and is even more exacerbated in end-stage renal disease patients undergoing maintenance hemodialysis. Although acting in the plasma as an antioxidant, once uric acid enters the intracellular environment; it behaves as a powerful pro-oxidant. Exogenous intake of antioxidants has been repeatedly shown to prevent inflammation, atherosclerosis and oxidative stress in CKD patients. Moreover, certain antioxidants have been proposed to exert uric acid-lowering properties. This review aims to present the available data regarding the effects of antioxidant supplements on both oxidative stress and uric acid serum levels, in a population particularly susceptible to oxidative damage such as CKD patients.

OBJECTIVE: To determine cut off value of procalciton (PCT) in aseptic end stage renal disease patients undergoing haemodialysis. BACKGROUND: Haemodialysisis considered as a proinflammatory state and therefore associated with release of inflammatory cytokines and acute phase reactant proteins. The conventional laboratory markers (C-reactive protein, erythrocyte sedimentation rate) are efficient tools for the diagnosis of infection in patients with normal kidney functions. However they can be nonspecifically elevated in patients on haemodialysis and only reflect inflammatory response not associated with infection. PCT is considered a very important biomarker in differentiating infections from inflammation. The study was undertaken to evaluate normal serum levels of PCT in patients undergoing HD.PATIENTS AND METHOD: The study included 82 end-stage renal failure patients without evidence of systemic or localized infection undergoing maintenance haemodialysis. RESULTS: In our study, the PCT concentrations showed a mean of .622ng/ml in patients on maintenance hemodialysis without signs of infection. CONCLUSION:The study suggests that serum PCT at a cutoff value of .62ng/ml should be considered normal in aseptic haemodialysis patients. KEYWORDS: Procalcitonin, haemodialysis, sepsis

Background and Objectives: The hemodialysis (HD) procedure may acutely induce regional left ventricular systolic dysfunction. This study evaluated the echocardiographic parameters in patients with End Stage Renal Disease (ESRD) on HD and to correlate those with clinical findings, more specifically to see whether there is any change in ejection fraction (EF) by developing new regional wall motion abnormality (RWMA) after hemodialysis, and to correlate these changes with the symptoms & hemodynamic condition of the patients.Methodology: This prospective observational study was carried on a total of 100 adult ambulant patients with end stage renal disease (ESRD) on maintenance hemodialysis in the department of Hemodialysis, BIRDEM General Hospital, Shahbag, Dhaka. Their echocardiogram was done 30 min before and after the hemodialysis.Result: It was revealed that majority of the patients were above 60 years (39%), and male to female ratio of about 3:2. The study subjects had diabetes mellitus (79%), hypertension (96%), dyslipidemia (42%), and family history of ischemic heart disease (24%). Chest pain and breathlessness were present in 31% and 42% subjects respectively before hemodialysis. Palpitation (23%), dizziness (19%), oedema (43%) and raised JVP (15%) were seen in the study subjects. Mean (±SD) serum creatinine level was 9.38 (±2.22) mg/dl and hemoglobin level was 9.0 (±1.08) g/dl. Ejection fraction (EF) before hemodialysis were ?55, 40-54 & 30-39 in 62%, 34% and 4% study subjects respectively and after hemodialysis it was ?55, 40-54 & 30-39 in 44%, 46% and 10% study subjects respectively. After HD, left ventricular failure (LVF) occurred in 32% subjects. HD-induced regional left ventricular systolic dysfunction occurred in total 36 patients (36%) and total 14 (14%) patients developed LVF 30 minutes after dialysis. Patients with hemodialysis-induced left ventricular systolic dysfunction were more in those who had worse predialysis EF. Blood pressure, heart rate, chest pain, palpitation, raised Jugular Venous Pressure (JVP) and edema did not differ significantly before and after hemodialysis. Simple regression analysis revealed that the hemodialysis procedure significantly (P<0.05) induce regional left ventricular systolic dysfunction.Conclusions: HD acutely induces regional wall motion abnormalities in a significant proportion of patients. It occurs within 30 min after hemodialysis and is not related to changes in blood pressure, heart rate, JVP and oedema.Bangladesh Crit Care J September 2017; 5(2): 97-100

Ceftriaxone (CTRX) is a third-generation cephalosporin widely used for the treatment of bacterial infections in patients with renal disease because of its excretion by both renal and hepatic mechanisms. Biliary pseudolithiasis is a known CTRX-associated complication; however, there have been no studies of this adverse event in adult patients receiving maintenance hemodialysis. Here we report the case of a 79-year-old Japanese woman with end-stage renal disease (ESRD) receiving maintenance hemodialysis who developed CTRX-induced pseudolithiasis. The patient received CTRX for bronchial pneumonia. Fifteen days following CTRX initiation, the patient presented with stomachache. Because of the presence of one gallstone and increased gallbladder wall thickness on computed tomography scans, not detected at the onset of pneumonia, the patient was diagnosed with CTRX-induced gallbladder pseudolithiasis. CTRX was discontinued immediately. At 48 days following CTRX withdrawal, the gallstone and thickening of the gallbladder wall had completely resolved. ESRD may be a risk factor for CTRX-induced pseudolithiasis as hepatic excretion of CTRX is the predominant clearance mechanism in patients with ESRD. More attention should be paid to CTRX-induced pseudolithiasis following the use of CTRX in ESRD patients.

Objectives An overlap between the somatic symptoms of depression and those of uremia seen in end-stage renal disease (ESRD) patients may affect the diagnosis of depression. This study aims to evaluate the effect of hemodialysis on the diagnosis of depression among patients on maintenance hemodialysis as dialysis diminishes the uremic symptoms, and to compare depression scores before and after dialysis. Methods This was a cross-sectional analytic study conducted from November 2018 through April 2019, in three tertiary hospitals. Consenting participants aged 18 years or older, who had received hemodialysis for at least three months were included. The Patient Health Questionnaire (PHQ-9) tool was used to collect patients’ data and to identify symptoms of depression Pre- and post-hemodialysis. Depression scores were compared using the paired sample Wilcoxon rank test or the McNemar test, where appropriate. Results Overall, 163 participants were enrolled in the study. The average age of the participants was 56.5 years old, whereas 44.8% were females. The prevalence of depressive symptoms before hemodialysis was 48.5%, with prevalence of mild, moderate and moderately severe of 34.4%, 11.7% and 2.5%, respectively. On the other hand, the prevalence of depressive symptoms after hemodialysis was 46.6% with 36.8%, 9.2% and 0.6% of the participants reporting mild, moderate and moderately severe symptoms, respectively. We found no significant difference in depression scores before and after dialysis (p-values > 0.05). Conclusion Our study supports the fact that the prevalence of depression is high among patients with ESRD on maintenance hemodialysis. We didn’t find a significant difference in depression scores among hemodialysis patients before and after dialysis, with negligible effect of uremic symptoms on the diagnosis of depression. We suggest adopting routine screening of depression among this high-risk group of patients.

Mineral and bone metabolism disorders are relatively common among patients with end-stage renal disease on maintenance hemodialysis. Corneal and conjunctival calcification is the main extravascular site for calcification. Recently, this form of calcification has been linked to vascular calcification. Secondary hyperparathyroidism can lead to high levels of calcium and phosphorus and increase the risk of calcification. Here, we report a case of a 38-year-old female with severe hyperparathyroidism who underwent eye examination before and after parathyroidectomy. Anterior segment optical coherence tomography showed an improvement in the number and size of ocular calcifications 6 months after surgery. This case calls attention to the importance of eye examination in patients on dialysis and brings the possibility of recovery of calcification in a short-term follow-up.

Abstract. Objective: Hemodialysis patients are prone to malnutrition because of diet or many uremic complications. The objective of this study is to determine whether thiamine deficiency is associated with regular dialysis patients. Methods: To determine whether thiamine deficiency is associated with regular dialysis patients, we measured thiamine in 100 patients undergoing consecutive dialysis. Results: Average thiamine levels were not low in both pre-hemodialysis (50.1 ± 75.9 ng/mL; normal range 24 - 66 ng/mL) and post-hemodialysis (56.4 ± 61.7 ng/mL). In 18 patients, post-hemodialysis levels of thiamine were lower than pre-hemodialysis levels. We divided the patients into two groups, the decrease (Δthiamine/pre thiamine < 0; - 0.13 ± 0.11) group (n = 18) and the increase (Δthiamine/pre thiamine> 0; 0.32 ± 0.21)) group (n = 82). However, there was no significance between the two groups in Kt/V or type of dialyzer. Patients were dichotomized according to median serum thiamine level in pre-hemodialysis into a high-thiamine group (≥ 35.5 ng/mL) and a low-thiamine group (< 35.4 ng/mL), and clinical characteristics were compared between the two groups. The low-thiamine value group (< 35.4 ng/ml; 26.8 ± 5.3 ng/ml) exhibited lower levels of serum aspartate aminotransferase and alanine aminotransferase than the high-thiamine value group (≥ 35.4 ng/ml; 73.5 ± 102.5 ng/ml) although there was no significance in nutritional marker, Alb, geriatric nutritional risk index , protein catabolic rate and creatinine generation rate. Conclusion: In our regular dialysis patients, excluding a few patients, we did not recognize thiamine deficiency and no significant difference in thiamine value between pre and post hemodialysis.

AbstractTrying to manage the dramatic coronavirus disease 2019 (COVID-19) infection spread, many countries imposed national lockdown, radically changing the routinely life of humans worldwide. We hypothesized that both the pandemic per se and the consequent socio-psychological sequelae could constitute stressors for Italian population, potentially affecting the endocrine system. This study was designed to describe the effect of lockdown-related stress on the hypothalamic-pituitary-thyroid (HPT) axis in a cohort of young men. A prospective, observational clinical trial was carried out, including patients attending the male infertility outpatient clinic before and after the national lockdown for COVID-19 pandemic. The study provided a baseline visit performed before and a follow-up visit after the lockdown in 2020. During the follow-up visit, hormonal measurements, lifestyle habits and work management were recorded. Thirty-one male subjects were enrolled (mean age: 31.6 ± 6.0 years). TSH significantly decreased after lockdown (p = 0.015), whereas no significant changes were observed in the testosterone, luteinising hormone, follicle-stimulating hormone, estradiol and prolactin serum levels. No patient showed TSH serum levels above or below reference ranges, neither before nor after lockdown. Interestingly, TSH variation after lockdown was dependent on the working habit change during lockdown (p = 0.042). We described for the first time a TSH reduction after a stressful event in a prospective way, evaluating the HPT axis in the same population, before and after the national lockdown. This result reinforces the possible interconnection between psychological consequences of a stressful event and the endocrine regulation.

AbstractMulti-organ fibrosis among end stage renal disease (ESRD) patients cannot be explained by uremia alone. Despite mitigation of thrombosis during hemodialysis (HD), subsequent platelet dysfunction and tissue dysregulation are less understood. We comprehensively profiled plasma and platelets from ESRD patients before and after HD to examine HD-modulation of platelets beyond thrombotic activation. Basal plasma levels of proteolytic regulators and fibrotic factors were elevated in ESRD patients compared to healthy controls, with isoform-specific changes during HD. Platelet lysate (PL) RNA transcripts for growth and coagulative factors were elevated post-HD, with upregulation correlated to HD vintage. Platelet secretome correlations to plasma factors reveal acutely induced pro-fibrotic platelet phenotypes in ESRD patients during HD characterized by preferentially enhanced proteolytic enzyme translation and secretion, platelet contribution to inflammatory response, and increasing platelet dysfunction with blood flow rate (BFR) and Vintage. Compensatory mechanisms of increased platelet growth factor synthesis with acute plasma matrix metalloproteinase (MMP) and tissue inhibitor of MMPs (TIMP) increases show short-term mode-switching between dialysis sessions leading to long-term pro-fibrotic bias. Chronic pro-fibrotic adaptation of platelet synthesis were observed through changes in differential secretory kinetics of heterogenous granule subtypes. We conclude that chronic and acute platelet responses to HD contribute to a pro-fibrotic milieu in ESRD.
