Impact of hypoalbuminemia on clinical outcomes among patients with obesity treated with ceftriaxone.

The use of ceftriaxone, a highly protein-bound drug, in the setting of hypoalbuminemia may result in suboptimal drug exposure. Patients with obesity also exhibit higher absolute drug clearance. We aimed to evaluate the impact of hypoalbuminemia on clinical success among hospitalized adults with obesity who were treated with ceftriaxone. This retrospective review included adult inpatients with weight >100 kg or body mass index >40 kg/m2 who received ceftriaxone 2 g intravenously every 12 hours for at least 72 hours. The primary outcome was clinical success, a composite of clinical cure and microbiologic cure. Secondary outcomes included clinical cure, microbiologic cure, length of stay, ICU length of stay, mortality, 30-day readmission, and adverse events. In all, 137 patients were included, 34 of whom had a serum albumin of ≤2.5 g/dL. In a propensity-score-weighted analysis, clinical success was significantly more common among those without hypoalbuminemia (91.2%) as compared to those with hypoalbuminemia (77.8%) (P = 0.038). Death within 30 days (13.7% vs 0%, P < 0.001) and 30-day readmission (31.6% vs 12.0%, P = 0.008) were more common in the hypoalbuminemia group. In a univariate analysis, serum albumin and indication for ceftriaxone use were found to be predictors of clinical success. Hypoalbuminemia was associated with a lower rate of clinical success among patients with obesity who were treated with ceftriaxone 2 g every 12 hours.

Resolution of hypoalbuminemia in a 3-year-old hound-mix dog after discontinuation of oclacitinib.

OBJECTIVE: Albumins are protein molecules that account for 50% of total plasma protein. They are imperative in maintaining intravascular colloidal oncotic pressure, act as key scavenger molecules for oxygen free radicals, and perform a major role in transporting numerous substances and in wound healing. Hypoalbuminemia has been reported as the consequence of decreased intake, increased loss, decreased production, and redistribution. While anecdotal evidence of tyrosine kinase inhibitors causing hypoalbuminemia in canine patients exists, to the author's knowledge there is no formal report to this effect to date. This case report aims to bridge the gap between anecdotal evidence and literature. ANIMAL: 3-year-old neutered male hound-mix canine. CLINICAL PRESENTATION, PROGRESSION, AND PROCEDURES: The patient was presented for recurrent otitis externa refractory to treatments with orbifloxacin/mometasone/posaconazole otic suspension, miconazole/polymyxin B/prednisolone otic suspension, ketoconazole/TrizEDTA, and gentamicin/mometasone/clotrimazole, which prompted consideration of oral antifungals. Baseline blood work prior to initiation of fluconazole showed elevated alkaline phosphatase. Treatment was initiated with fluconazole, and blood work was rechecked and revealed hypoalbuminemia. Multiple diagnostic tests failed to reveal a cause of hypoalbuminemia. TREATMENT AND OUTCOME: Discontinuation of oclacitinib that the patient was being administered resulted in normalization of serum albumin. CLINICAL RELEVANCE: It is unclear whether hypoalbuminemia associated with oclacitinib administration is associated with worse outcomes for pathologies in canine patients; however, this seems to be the case in humans according to some reports. This report aims to take a step in the direction of this knowledge.

Diagnosis and treatment of Tropheryma whipplei infection in patients with inflammatory rheumatic disease: Data from the French Tw-IRD registry.

OBJECTIVES: Tropheryma whipplei infection can manifest as inflammatory joint symptoms, which can lead to misdiagnosis of inflammatory rheumatic disease and the use of disease-modifying antirheumatic drugs. We investigated the impact of diagnosis and treatment of Tropheryma whipplei infection in patients with inflammatory rheumatic disease. METHODS: We initiated a registry including patients with disease-modifying antirheumatic drugs-treated inflammatory rheumatic disease who were subsequently diagnosed with Tropheryma whipplei infection. We collected clinical, biological, treatment data of the inflammatory rheumatic disease, of Tropheryma whipplei infection, and impact of antibiotics on the evolution of inflammatory rheumatic disease. RESULTS: Among 73 inflammatory rheumatic disease patients, disease-modifying antirheumatic drugs initiation triggered extra-articular manifestations in 27% and resulted in stabilisation (51%), worsening (34%), or improvement (15%) of inflammatory rheumatic disease. At the diagnosis of Tropheryma whipplei infection, all patients had rheumatological symptoms (mean age 58 years, median inflammatory rheumatic disease duration 79 months), 84% had extra-rheumatological manifestations, 93% had elevated C-reactive protein, and 86% had hypoalbuminemia. Treatment of Tropheryma whipplei infection consisted mainly of doxycycline plus hydroxychloroquine, leading to remission of Tropheryma whipplei infection in 79% of cases. Antibiotic treatment of Tropheryma whipplei infection was associated with remission of inflammatory rheumatic disease in 93% of cases and enabled disease-modifying antirheumatic drugs and glucocorticoid discontinuation in most cases. CONCLUSIONS: Tropheryma whipplei infection should be considered in inflammatory rheumatic disease patients with extra-articular manifestations, elevated C-reactive protein, and/or hypoalbuminemia before disease-modifying antirheumatic drugs initiation or in inflammatory rheumatic disease patients with an inadequate response to one or more disease-modifying antirheumatic drugs. Positive results of screening and diagnostic tests for Tropheryma whipplei infection involve antibiotic treatment, which is associated with complete recovery of Tropheryma whipplei infection and rapid remission of inflammatory rheumatic disease, allowing disease-modifying antirheumatic drugs and glucocorticoid discontinuation.

Associated factors with liver fibrosis in rheumatoid arthritis patients treated with methotrexate.

INTRODUCTION: There are conflicting findings on the link between liver fibrosis and cumulative methotrexate dosages. We aimed to determine the frequency of liver fibrosis in rheumatoid arthritis patients treated with methotrexate and to identify its associated factors. METHODS: We conducted a cross-sectional study over 9 months (April-December 2021), including rheumatoid arthritis patients treated with methotrexate. Demographic and clinical data were collected. Liver stiffness was assessed by FibroScan. Fibrosis and significant liver fibrosis were defined as liver stiffness higher than 6 and 7.2 kPa, respectively. Liver tests, albuminemia, lipid profile, and blood glycemia were measured. Metabolic syndrome was also evaluated. Statistical analyses were performed using SPSS. RESULTS: We included 21 men and 47 women. The mean age was 51.60 ± 1.82 years. The mean disease duration was 8.29 ± 6.48 years. The mean weekly intake of methotrexate was 13.76 ± 3.91 mg. The mean methotrexate duration was 4.67 ± 4.24 years. The mean cumulative dose was 3508.87 ± 3390.48 mg. Hypoalbuminemia and metabolic syndrome were found in 34% and 25% of cases. We noted increased alkaline phosphatase levels in four cases. The mean liver stiffness was 4.50 ± 1.53 kPa. Nine patients had liver fibrosis, and four had significant fibrosis. Associated factors with liver fibrosis were as follows: age ≥ 60 years (OR:22.703; 95%CI [1.238-416.487]; p = 0.035), cumulated dose of methotrexate ≥ 3 g (OR: 76.501; 95%CI [2.383-2456.070]; p = 0.014), metabolic syndrome (OR: 42.743; 95%CI [1.728-1057.273]; p = 0.022), elevated alkaline phosphatase levels (OR: 28.252; 95%CI [1.306-611.007]; p = 0.033), and hypoalbuminemia (OR: 59.302; 95%CI [2.361-1489.718]; p = 0.013). CONCLUSION: Cumulating more than 3 g of methotrexate was associated with liver fibrosis in rheumatoid arthritis patients. Having a metabolic syndrome, higher age, hypoalbuminemia, and elevated alkaline phosphatase levels were also likely to be independently associated with liver fibrosis. Key points • Rheumatoid arthritis patients require monitoring hepatic fibrosis when the cumulated dose of methotrexate is above 3 g. • Metabolic syndrome is a risk factor for liver fibrosis, suggesting that its management is necessary to prevent this complication. • Hypoalbuminemia and elevated alkaline phosphatase levels (twice the upper limit) in rheumatoid arthritis patients treated with methotrexate were associated with liver fibrosis.

Doxorubicin and zoledronate treatment in a dog with hemophagocytic histiocytic sarcoma.

A 6-year-old castrated male greyhound dog was referred for hemophagocytic histiocytic sarcoma (HHS) diagnosed following splenectomy. Severe thrombocytopenia, mild hypoalbuminemia, mild hypocholesterolemia, and mild hyperbilirubinemia were present. Abdominal ultrasound findings were concerning for hepatic metastasis. Doxorubicin and zoledronate combination therapy was initiated. The dog improved clinically and its thrombocytopenia, hypoalbuminemia, and hyperbilirubinemia resolved. The dog appeared well for 147 d before tumor progression was noted. The dog was treated with lomustine as a final measure, with no response. The dog survived for 6 mo with chemotherapy. To the authors' knowledge, this is the first report of clinical benefit of chemotherapy for HHS. Key clinical message: Doxorubicin should be considered for treating canine HHS since this variant of the disease is historically refractory to lomustine. Further research regarding efficacy of doxorubicin and zoledronate should be pursued.

Traitement à la doxorubicine et au zolédronate chez un chien atteint de sarcome histiocytaire hémophagocytaire. Un lévrier mâle castré de 6 ans a été vu pour un sarcome histiocytaire hémophagocytaire (HHS) diagnostiqué à la suite d'une splénectomie. Une thrombopénie sévère, une hypoalbuminémie légère, une hypocholestérolémie légère et une hyperbilirubinémie légère étaient présentes. Les résultats de l'échographie abdominale étaient préoccupants quant aux métastases hépatiques. Un traitement associant doxorubicine et zolédronate a été instauré. Le chien s'est amélioré cliniquement et sa thrombocytopénie, son hypoalbuminémie et son hyperbilirubinémie ont disparu. Le chien semblait en bonne santé pendant 147 jours avant de constater une progression tumorale. Le chien a été traité avec de la lomustine comme mesure finale, sans réponse. Le chien a survécu 6 mois grâce à la chimiothérapie. À la connaissance des auteurs, il s'agit du premier rapport faisant état d'un bénéfice clinique de la chimiothérapie pour le HHS.Message clinique clé :La doxorubicine doit être envisagée pour traiter le HHS canin puisque cette variante de la maladie est historiquement réfractaire à la lomustine. Des recherches plus approfondies concernant l'efficacité de la doxorubicine et du zolédronate devraient être poursuivies.(Traduit par Dr Serge Messier).

Controversies Surrounding Albumin Use in Sepsis: Lessons from Cirrhosis.

This narrative review critically examines the role of albumin in sepsis management and compares it to its well-established application in liver cirrhosis. Albumin, a key plasma protein, is effective in the management of fluid imbalance, circulatory dysfunction, and inflammation-related complications. However, its role in sepsis is more intricate and characterized by ongoing debate and varied results from clinical studies. In sepsis, the potential benefits of albumin include maintaining vascular integrity and modulating inflammation, yet its consistent clinical efficacy is not as definitive as that in cirrhosis. This review evaluated various clinical trials and evidence, highlighting their limitations and providing practical insights for clinicians. It emphasizes identifying sepsis patient subgroups that are most likely to benefit from albumin therapy, particularly exploring the correction of hypoalbuminemia. This condition, which is significantly corrected in patients with cirrhosis, may have similar therapeutic advantages in sepsis. The potential effectiveness of albumin in the low-volume resuscitation and deresuscitation phases of sepsis management was noted. Given the safety concerns observed in cirrhosis, such as pulmonary edema and hypervolemia associated with albumin therapy, cautious integration of albumin into sepsis treatment is mandatory. Personalized albumin therapy is advocated for tailoring strategies to the specific needs of each patient, based on their clinical presentation and underlying conditions. The need for further research to delineate the role of albumin in sepsis pathophysiology is underscored. The review emphasizes the importance of conducting trials to assess the effectiveness of albumin in correcting hypoalbuminemia in sepsis, its impact on patient outcomes, and the establishment of appropriate dosing and administration methods. This approach to albumin use in sepsis management is posited as a way to potentially improve patient outcomes in this complex clinical scenario while being mindful of the lessons learned from its use in cirrhosis.

Response and survival of dogs with proteinuria (UPC > 2.0) treated with angiotensin converting enzyme inhibitors.

BACKGROUND: Angiotensin-converting enzyme inhibitors (ACEi) are a recommended treatment for glomerular proteinuria. Frequency of response to ACEi and the association of achieving proposed urine protein-to-creatinine ratio (UPC) targets on survival is unknown. OBJECTIVES: To determine response rates to ACEi therapy and whether a positive response is associated with improved survival. ANIMALS: Eighty-five dogs with proteinuria (UPC > 2.0). METHODS: Retrospective study including dogs (UPC > 2.0) prescribed an ACEi for treatment of proteinuria. Baseline creatinine, albumin, cholesterol, UPC, and systolic blood pressure were recorded, and cases reviewed to track UPC. Treatment response was defined as achieving a UPC of <0.5 or reduction of ≥50% from baseline within 3 months. Outcome data were collected to determine overall and 12-month survival. RESULTS: Thirty-five (41%) dogs responded to ACEi treatment. Treatment response was statistically associated with both median survival time (664 days [95% confidence interval (CI): 459-869] for responders compared to 177 [95% CI: 131-223] for non-responders) and 12-month survival (79% responders alive compared to 28% non-responders). Baseline azotemia or hypoalbuminemia were also associated with a worse prognosis, with odds ratios of death at 12 months of 5.34 (CI: 1.85-17.32) and 4.51 (CI: 1.66-13.14), respectively. In the 25 dogs with normal baseline creatinine and albumin, response to treatment was associated with 12-month survival (92% responders alive compared to 54% non-responders, P = .04). CONCLUSIONS AND CLINICAL IMPORTANCE: When the UPC is >2.0, achieving recommended UPC targets within 3 months appears to be associated with a significant survival benefit. Response to treatment is still associated with survival benefit in dogs with less severe disease (no azotemia or hypoalbuminemia).

Albumin administration in internal medicine: A journey between effectiveness and futility.

Albumin is the most abundant circulating protein and provides about 70% of the plasma oncotic power. The molecule also carries many other biological functions (binding, transport and detoxification of endogenous and exogenous compounds, antioxidation, and modulation of inflammatory and immune responses). Hypoalbuminemia is a frequent finding in many diseases, representing usually only a biomarker of poor prognosis rather than a primary pathophysiological event. Despite that, albumin is prescribed in many conditions based on the assumption that correction of hypoalbuminemia would lead to clinical benefits for the patients. Unfortunately, many of these indications are not supported by scientific evidence (or have been even disproved), so that a large part of albumin use is nowadays still inappropriate. Decompensated cirrhosis is the clinical area where albumin administration has been extensively studied and solid recommendations can be made. Besides prevention and treatment of acute complications, long-term albumin administration in patients with ascites has emerged in the last decade has a potential new disease-modifying treatment. In non-hepatological settings, albumin is widely used for fluid resuscitation in sepsis and critical illnesses, with no clear superiority over crystalloids. In many other conditions, scientific evidence supporting albumin prescription is weak or even absent. Thus, given its high cost and limited availability, action is needed to avoid the use of albumin for inappropriate and futile indications to ensure its availability in those conditions for which albumin has been demonstrated to have a real effectiveness and an advantage for the patient.

Pediatric Liver Abscess: Outcomes of Protocol-based Management and Predictors of Poor Outcome.

BACKGROUND: Liver abscess (LA) is an important cause of morbidity in children, especially in tropical countries. There is a paucity of data in pediatric LA with no standard guidelines regarding the best modality of treatment and drainage. With a large influx of patients at our center and protocol-based management; we aimed to study clinic-radiologic profile, risk factors, complications and outcomes of children with liver abscess and assessed possible predictors for poor outcomes. MATERIALS AND METHODS: This retrospective observational study was conducted from January 2019 to September 2019 at a tertiary care hospital in India. Records of all children (<12 years of age) with ultrasonographically diagnosed liver abscess were accessed for clinic-radiological and demographic profile, laboratory investigations, treatment, complications and outcomes. Patients were categorized into favorable or unfavorable groups based on predefined criteria and were compared for possible predictors of poor outcomes. Outcomes for the protocol-based management were analyzed. RESULTS: There were 120 cases of pediatric liver abscess with a median age of 5 years at presentation. The commonest clinical features were fever (100%) and pain in the abdomen (89.16%). The majority of liver abscesses were solitary (78.4%) and in the right lobe (73.3%). Malnutrition was present in 27.5%, overcrowding for 76.5% of patients and worm infestation in 2.5% of patients. Age-related leukocytosis ( P = 0.004), neutrophilia ( P = 0.013), elevated Aspartate transaminase ( P = 0.008), elevated alanine transaminase ( P = 0.007) and hypoalbuminemia ( P = 0.014) were significantly more in the unfavorable group. Overall, 29.2% of patients underwent conservative management with antibiotics alone, 25.0% underwent percutaneous needle aspiration (PNA), 49.1% underwent ultrasound-guided percutaneous drain (PCD) insertion and open surgical drainage (OSD) was needed in a single patient. The success rate was 100% for conservative management, 76.6% for PNA, 94.7% for PCD and 100% for OSD with an overall mortality of 2.5%. CONCLUSIONS: Age-related leukocytosis, neutrophilia, elevated aspartate transaminase or alanine transaminase and hypoalbuminemia at presentation are predictors of poor outcomes in pediatric liver abscess. Protocol-based management leads to the appropriate use of PNA and PCD while decreasing mortality and morbidity related to either.

Some Points for the KDIGO 2021 Guideline for Prophylactic Anticoagulation in Membranous Nephropathy: Is It Clear Enough for Us to Follow?

CONTEXT: Patients with membranous nephropathy (MN) are recognized as individuals with high risk of thrombosis. However, prophylactic anticoagulant therapy in this population is still a controversial topic for a lack of high-quality evidence. Subject of Review: The Kidney Disease: Improving Global Outcomes (KDIGO) 2021 Clinical Practice Guideline for the Management of Glomerular Diseases was published in Kidney International in October 2021, and it was updated on the topic of prophylactic anticoagulant therapy in patients with MN. Differing from the previous main concern about the risk of venous thromboembolism (VTE) in MN, it paid attention to the risk of arterial thromboembolism (ATE) as well. Additionally, the risk of ATE was considered to be associated with hypoalbuminemia. A tool for evaluating the risk of bleeding in patients with MN was proposed in the KDIGO 2021 guideline, and individuals with low risk of bleeding as well as high risk of VTE were suggested to use warfarin or low-molecular-weight heparin (LMWH) combined with aspirin, as an alternative regimen for warfarin. Second Opinion: Our analysis shows that no consensuses have been reached on whether the prevention of ATE is necessary for patients with MN or whether the risk of ATE is associated with hypoalbuminemia. The proposed tool is not the only choice of tools for bleeding assessment, and the HAS-BLED risk score might be a better choice from the perspective of general applicability and availability. Furthermore, in our opinion, the suggestion for prophylaxis regimen of LMWH combined with aspirin showed a lack of consideration and might be inappropriate to some degree. In summary, there are still many controversies in the field of prophylactic anticoagulation for MN; as a consequence, more high-quality studies are required to provide guidance.

Moderator Effect of Hypoalbuminemia in Volume Resuscitation and Plasma Expansion with Intravenous Albumin Solution.

Intravenous administration of crystalloid or colloid solutions is the most common intervention for correcting hypovolemia in intensive care unit patients. In critical illness, especially sepsis and severe trauma, vascular wall permeability increases, and trans-endothelial escape of serum albumin, the major oncotic plasma constituent, contributes to the development of hypoalbuminemia and edema formation. The volume effects of intravenous human albumin solution exceed those of crystalloid solutions. If hypoalbuminemia is an effect moderator, the crystalloid-to-albumin ratio of fluid resuscitation volumes is not well characterized. Randomized controlled trials have confirmed that intravenous administration of human albumin solutions for volume resuscitation results in a lower net fluid balance compared with crystalloids, and smaller infusion volumes may be sufficient for hemodynamic stabilization when human albumin solutions are used. This narrative review summarizes the current evidence and conclusions drawn regarding the role of hypoalbuminemia in volume resuscitation. In the 'Saline versus Albumin Fluid Evaluation' study using 4% human albumin solution or saline, the saline-to-albumin ratio of study fluids was significantly higher in patients with baseline serum albumin concentrations of 25 g/L or less as compared to patients with baseline serum albumin concentrations of more than 25 g/L. In patients receiving renal replacement therapy, intravenous administration of 20-25% human albumin solution reduces intradialytic hypotension and improves fluid removal better than saline if serum albumin levels are similarly reduced. These data suggest that hypoalbuminemia acts as an effect moderator in volume resuscitation and plasma expansion with albumin solution. The volume effectiveness of intravenous human albumin solution in resuscitation appears to be greater when the serum albumin levels are low. In clinical situations, serum albumin concentrations per se may inform when and how to include intravenous albumin in fluid resuscitation if large amounts of crystalloids are needed, which requires further studies.

The correlation between paclitaxel chemotoxicity and the plasma albumin level in cancer patients.

WHAT IS KNOWN AND OBJECTIVE: The aim of this study was to evaluate the pharmacokinetics of paclitaxel in cancer patients with hypoalbuminemia following paclitaxel-containing chemotherapy and to provide a reference for the prevention of adverse events (AEs) after paclitaxel administration. METHODS: Peripheral blood was collected from cancer patients treated with paclitaxel. The plasma concentration of paclitaxel was determined by ultra-high performance liquid chromatography after 24 ± 8 h of chemotherapy, and individual paclitaxel time above a threshold concentration of 0.05 µmol/L (Tc>0.05 ) was calculated using the population pharmacokinetic model. Haematological and non-haematological toxicities were monitored after chemotherapy, and the correlation between different chemotherapy toxicities and Tc>0.05 was evaluated using the Prism software. RESULTS AND DISCUSSION: The enrolled patients were divided into the hypoalbuminemia group and normal albumin level group. The mean Tc>0.05 values in the normal albumin level and hypoalbuminemia groups were 36.89 and 24.93 h, respectively (P < 0.001). The risk of myelosuppression was positively correlated with Tc>0.05 . Due to the lower Tc>0.05 , the incidences of immediate AEs such as gastrointestinal reactions and rashes were higher in the hypoalbuminemia group than in the normal albumin level group, and the incidences of delayed AEs such as myelosuppression and neurotoxicity were lower in the hypoalbuminemia group. WHAT IS NEW AND CONCLUSIONS: Plasma albumin level has a conclusive effect on Tc>0.05 , which can predict the potential clinical toxicity of paclitaxel. The study provides a theoretical basis for administration of paclitaxel.

Use of Albumin in the NICU: An Evidence-based Review.

Albumin is the most abundant protein in human blood with distinctive functions throughout the human body. Low albumin levels are a predictor of mortality as well as disease outcome in children and adults. However, the clinical significance of hypoalbuminemia and the role of albumin infusions in NICUs remain unclear and controversial.

Establishment of relapse risk model and multivariate logistic regression analysis on risk factors of relapse in children with primary nephrotic syndrome.

This study aimed to investigate relapse risk factors in children with primary nephrotic syndrome (PNS) for prevention and early intervention via logistic regression. One hundred thirty-seven children with PNS were enrolled in this study. Clinical variables were analyzed by single-factor and multiple regression analysis to establish the regression equation. The predictive ability of the regression equation was investigated by the receiver operating characteristic curve (ROC). Files of 17 patients were lost, and 120 patients were enrolled finally in the study, among whom 55 cases (45.8%) had frequently relapsed. Single-factor analysis and multiple regression analysis revealed that concurrent infection on first onset, irregular glucocorticoid therapy, severe hypoalbuminemia, and persistent severe hyperlipidemia were the significant risk factors for frequent relapse on PNS (P < .05), among which infection remained to be the main inductive factor. Among the 4 indicators, serum albumin had the best diagnostic efficacy based on the area under the ROC curve (0.933), sensitivity (89.09%), and specificity (81.54%). The area under curve, sensitivity, and specificity for the combined diagnostic model of the 4 indices were 97.8%, 98.18%, and 90.77%, respectively, which had good predictive power for the relapse of patients. Concurrent infection, irregular glucocorticoid therapy, severe hypoalbuminemia, and persistent severe hyperlipemia were all the risk factors for PNS relapse. The established logistic regression model based on these factors above is reliable for predicting frequent PNS relapse. Much attention should be paid to these critical factors, and early intervention should be taken to reduce the incidence of relapse.

A 6-Month clinical practice pilot study of sucroferric oxyhydroxide on nutritional status in patients on peritoneal dialysis.

BACKGROUND: Hyperphosphatemia is common in patients on peritoneal dialysis (PD). Restricting dietary phosphorus often leads to a decrease in protein intake, which may result in hypoalbuminemia. The high pill burden of phosphate binders may also contribute to compromised appetite and dietary intake. Hypoalbuminemia is associated with an increased risk of morbidity and mortality in PD patients. The goal of this study was to determine if sucroferric oxyhydroxide improves albumin and self-reported measures of appetite in PD patients. METHODS: We performed a prospective, open-label, 6-month, pilot study of 17 adult PD patients from the Denver Metro Area. Patients had to use automated peritoneal dialysis for ≥ 3 months, have a serum albumin ≤ 3.8 g/dL, and have serum phosphate ≥ 5.5 mg/dL or ≤ 5.5 mg/dL on a binder other than SO. SO was titrated to a goal serum phosphate of < 5.5 mg/dL. The primary outcome was change in serum phosphate, albumin, and phosphorus-attuned albumin (defined as albumin divided by phosphorus) over 6 months. RESULTS: The mean (SD) age and dialysis vintage was 55 ± 13 years and 3.8 ± 2.7 years, respectively. Participants' serum phosphate significantly decreased with fewer phosphate binder pills/day after switching to SO. There was no change in serum albumin, appetite, or dietary intake. However, participants had significant improvements in phosphorus-attuned albumin. CONCLUSION: The transition to SO improved phosphorus control, phosphorus-attuned albumin, and pill burden. There were no significant changes in self-reported appetite or dietary intake during the study. These findings suggest that PD patients maintained nutritional status with SO therapy. TRIAL REGISTRATION: First registered at ClinicalTrials.gov ( NCT04046263 ) on 06/08/2019.

[Risk of infection in cancer patients colonized by extended expectrum p-lactamases and carbapenem producing Enterobacteriaceae]. / Riesgo de infección en pacientes oncológicos colonizados por bacterias productoras de p-lactamasas de espectro extendido y enterobacterias productoras de carbapenemasas.

BACKGROUND: The prevalence of multi-resistant microorganisms is a public health problem that continues to grow globally. There is a population that is mainly susceptible to being colonized and subsequently infected, and these are cancer patients. AIM: To identify the clinical and pathological characteristics of cancer patients and their relationship with infection with ESBL and CPE producing microorganisms. METHODS: A retrospective and analytical study was conducted between January 1, 2019 and June 30, 2020 in three hematooncological units. RESULTS: We included 3315 patients of which 217 (6.5%) were colonized by microorganisms producing ESBL and CPE. Of these, 106/217 (48.8%) had at least one episode of infection. The most frequently isolated microorganism was Klebsiella pneumoniae 29/106 (27.4%). Of those infected, 18/106 (17%) presented infection by the same colonizing microorganism. Mucositis (p = 0.002), age over 65 years (p = 0.041), hypoalbuminemia (p < 0.01), neutropenia (p < 0.01) and the presence of invasive devices (p < 0.01) demonstrated a relationship with development of infection. The presence of hypoalbuminemia (OR 3.3, CI 1.5-7.1, P < 0.01), invasive devices (OR 5.8, CI 3.0-11.4, p < 0.01) and neutropenia (OR 4.1, CI 1.5-11.4, p < 0.01) predict the development of infections.

Crotalid Polyvalent F(ab)2 Antivenom Treatment in a Red-Tailed Hawk (Buteo jamaicensis).

Envenomation in avian species can result in death, with few cases of successful treatment described. A juvenile, wild-caught, intact female red-tailed hawk (Buteo jamaicensis) used in falconry was presented for emergency evaluation after being bitten by a Northern Pacific rattlesnake (Crotalus oreganus) approximately 2 hours before presentation. On presentation, the bird was quiet, alert, and responsive, with moderate swelling and discomfort of the digits on the right foot. Complete blood count (CBC) and plasma biochemistry abnormalities included a regenerative left shift, severe lymphopenia, and a moderate hypoproteinemia characterized by moderate hypoalbuminemia. Analgesic and antibiotic medications were administered during hospitalization. In addition, 5 mL of VenomVet was administered intravenously with crystalloid fluids over 60 minutes; no adverse effects were noted secondary to infusion. Improvement in the swelling was observed immediately after antivenom administration and nearly resolved within 12 hours. Complete resolution of digital swelling with no discomfort on palpation of that foot was observed 1 week after initial presentation. Blood collected at the 1 week reexamination was submitted for a CBC and plasma biochemistry panel. The results of the CBC revealed a reduced regenerative left shift, increased heterophil count, and a moderate monocytosis; the lymphopenia was resolved. A mild hypoalbuminemia still persisted. Ten months after presentation, the bird was reported to be doing well with no changes in function of the right foot and subsequently released from captivity.

Baseline Factors Predictive of the Receipt of Second-Line Chemotherapy After Nab-Paclitaxel Plus Gemcitabine for Patients With Advanced Pancreatic Cancer.

OBJECTIVE: Second-line (2L) chemotherapy is important for improved survival in patients with advanced pancreatic cancer (APC). However, approximately half of patients with APC do not receive 2L chemotherapy because of disease progression or adverse events. Baseline factors predictive of the receipt of 2L chemotherapy remain unknown. Therefore, we investigated predictive factors for the receipt of 2L chemotherapy in patients with APC. METHODS: Between January 2015 and March 2020, 53 patients with APC received nab-paclitaxel plus gemcitabine (AG) as first-line chemotherapy at our institute. Of these 53 patients, 29 patients received 2L chemotherapy, and 23 patients received best supportive care. Patients' characteristics were compared retrospectively, and predictive factors for the receipt of 2L chemotherapy were evaluated. RESULTS: Sarcopenia and hypoalbuminemia at baseline were independent negative predictive factors for the receipt of 2L chemotherapy in multivariate analysis. Although the presence of sarcopenia did not affect the relative dose intensity through 8 weeks of AG therapy, patients with hypoalbuminemia had a significantly lower relative dose intensity. CONCLUSIONS: Sarcopenia and hypoalbuminemia at baseline might be negative predictive factors for the receipt of 2L chemotherapy after AG treatment in patients with APC.

Eosinophilic enteritis accompanied by cytomegalovirus disease: a case report.

BACKGROUND: Eosinophilic enteritis is a chronic inflammatory disorder of the intestinal tract that is characterized by eosinophil infiltration. Cytomegalovirus (CMV), a common virus, has a broad infectivity range. CMV is retained in the host body after infection. Impairment of host immune defences may reactivate the latent CMV, leading to symptoms of overt disease. CASE PRESENTATION: A Japanese female in her 70 s was admitted to a hospital due to diarrhoea and then transferred to our hospital. Laboratory data showed hypoalbuminemia. Computed tomography (CT) revealed oedema of the small intestine. Lower gastrointestinal endoscopy revealed oedema of the submucosa, without any remarkable changes in the mucosa of the terminal ileum. Histological examination of the terminal ileum revealed infiltration of > 20 eosinophils per high-power field (HPF). These findings aided in diagnosing eosinophilic enteritis. We administered methylprednisolone (500 mg/day) for three days, followed by tapering prednisolone. However, the patient's general condition and hypoalbuminemia failed to improve. Immunoglobulin (Ig) G- CMV and IgM-CMV tests were positive. CMV antigenemia was extremely high. Therefore, we administered ganciclovir intravenously, which improved the patient's condition. Furthermore, azathioprine was administered to taper and discontinue prednisolone without relapse of eosinophilic enteritis. This treatment helped stabilize the patient's condition for approximately four years. CONCLUSION: We present a case of eosinophilic enteritis accompanied by CMV disease during prednisolone treatment. The patient's condition improved after administration of ganciclovir. Azathioprine aided in discontinuing prednisolone and stabilizing the patient's condition for approximately four years.
