Relationships between creatinine increase and mortality rates in patients given vancomycin in 76 hospitals: The increasing role of infectious disease pharmacists

Abstract Purpose Vancomycin is a commonly used antimicrobial with the potential for renal toxicity. We evaluated vancomycin duration, changes in renal function after vancomycin initiation (“post-vancomycin” renal function changes), and associated mortality risk among hospitalized patients. Methods We analyzed data from 76 hospitals and excluded patients with a baseline serum creatinine concentration (SCr) of >3.35 mg/dL. We estimated mortality risk relative to vancomycin duration and the magnitude of post-vancomycin SCr change, controlling for demographics, baseline SCr, underlying diseases, clinical acuity, and comorbidities. Results Among 128,993 adult inpatients treated with vancomycin, 49.0% did not experience SCr elevation. Among the remaining patients, 26.0%, 11.4%, 8.8% and 4.8% experienced increases in post-vancomycin SCr of 1% to 20%, 21% to 40%, 41% to 100%, and greater than 100%, respectively. Compared to mortality risk among patients with a vancomycin therapy duration between 4 and 5 days (the lowest-mortality group), longer vancomycin therapy duration was not independently associated with higher mortality risk after adjusting for confounders. In contrast, there was a graded relationship between post-vancomycin SCr elevation and mortality. Multivariable adjusted mortality odds ratios ranged from 1.60 to 13.66, corresponding to SCr increases of 10% and greater than 200%, respectively. Conclusion Half of patients given vancomycin did not experience SCr elevation and had the lowest mortality, suggesting that vancomycin can be used safely if renal function is stabilized. In the large study cohort, vancomycin duration itself was not an independent predictor of mortality. Post-vancomycin SCr elevation appeared to be a driver of in-hospital mortality. Even a 10% SCr increase from baseline prior to vancomycin infusion was associated with increased mortality risk. This finding stresses the importance of closely monitoring renal function and may support the value of pharmacokinetic dosing.

Worsening Renal Function

Abstract Background Chronic kidney disease (CKD) is an important outcome predictor in patients with atrial fibrillation (AF). Moreover, renal function at baseline is used to guide oral anticoagulant (OA) selection and dosing at initial treatment. The prognostic role of worsening renal function (WRF) during treatment with direct oral anticoagulants (DOACS) has been poorly explored. Purpose To estimate the prognostic role of WRF in terms of major adverse cardiovascular events (MACEs) in a series of patients with newly diagnosed non-valvular AF (NVAF) treated with DOACs. Methods Among all patients with newly diagnosed NVAF and indication for OA between January 2017 and December 2018, we enrolled those treated with DOACs. Renal function at baseline and during follow-up was assessed with estimated glomerular filtration rates (eGFR). eGFR was calculated as a mean value of Cockcroft-Gault (CG), Modification of Diet in Renal Disease (MDRD) and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formulas. The hemorrhagic risk at baseline was estimated with the main available scores (HAS-BLED, ATRIA and ORBIT). WRF was defined as a decrease in eGFR of at least 20%. MACEs were evaluated according to the type of DOAC and the WRF. Major bleedings (MB) were defined according to the ISTH definition. Results The study population was constituted by 249 patients with newly diagnosed NVAF started on DOAC and followed for a median time of 14.1±8.6 months. Overall, WRF was observed in 58 cases (23.3%). Patients with WRF had significative higher rates of death (10.3% versus 3.1%, p=0.025) and MB (13.8% versus 4.7%, p=0.016). The incidence of bleeding events, acute coronary syndromes and stroke was not affected by WRF. Interestingly, CG formula better predicted the incidence of MB as compared to the other formulas (p=0.006). The type of DOAC did not significantly impact the observed renal impairment and had no effect on the occurrence of MACEs in patients showing WRF. The predictors of WRF were found to be age, female sex, low hemoglobin level and left ventricle end telediastolic volume. At multivariate analysis, WRF was identified as an independent predictor of MB (OR 3.1, 95% C.I, 1.12–8.58), regardless of the baseline bleeding risk. Conclusion This is the first prospective study to evaluate the impact of worsening renal function on cardiovascular events in patients with atrial fibrillation treated with DOACs. A significant WRF emerged as an independent predictor of death and MB. The specific DOAC did not affect either the entity of worsening renal function or the incidence of cardiovascular events.

Objective: The present study investigates a score based on baseline C-reactive protein (CRP) and fibrinogen values (FC score) in 173 consecutive glioblastoma (GBM) patients.Methods: The optimal cut-off value for fibrinogen and CRP was defined as 3.5 g/dl and 3.0 mg/L, respectively, according to previous reports. Patients with elevated CRP and fibrinogen were classified with a score of 2, those with an elevation of only one of these parameters were allocated a score of 1, and those without any abnormalities were assigned a score of 0.Results: No significant differences in age, gender, tumor area, molecular pathology, physical status, or extent of resection were identified among the three groups defined by this score. Univariate survival analysis demonstrated that a high baseline FC score (≥1) is significantly associated with a shortened overall survival (OS) (HR: 1.52, 95% CI: 1.05–2.20, p = 0.027). A multivariate Cox regression analysis considering age (>65/≤65), extent of resection (GTR/STR), MGMT promoter status (hypermethylated/non-hypermethylated), and FC score (0/≥1) confirmed that an elevated FC score (≥1) is an independent predictor of shortened OS (HR: 1.71, 95% CI: 1.16–2.51, p = 0.006).Conclusions: The baseline fibrinogen and CRP score thus serves as an independent predictor of OS in GBM. Further investigations of the role of inflammation in the prediction of a prognosis are needed.

SummaryTBeta-thromboglobulin (βTG) is a platelet-specific protein and since its concentration in plasma rises when platelets are activated, it has been used as an indicator of platelet involvement in vascular disease. Since platelets might be involved in the pathogenesis of diabetic microvascular disease we measured urinary βTG in 20 insulin-dependent diabetics with nephropathy and compared the results with those from 20 normal subjects. Measurement of βTG in urine was undertaken to avoid errors induced by blood sampling and to gain information over a prolonged period using a single assay. Measurements were made of βTG, β2-microglobulin and total protein in urine collected for 24 h and creatinine and β2 microglobulin in plasma. Survival of indium-111-labelled platelets was measured in nine patients. Urinary PTG was significantly (p <0.02) increased in the 20 patients compared with 20 normal volunteers (median value 1.3 vs 0.8 μg/24 h). There was a strong correlation between urinary βTG excretion and plasma creatinine concentration (r = 0.8, p <0.0001) and plasma β2-microglobulin concentration (r = 0.9, p <0.0001). Urinary βTG concentration did not correlate with platelet survival. The results indicate that although urinary βTG is significantly increased in patients with diabetic nephropathy its concentration in urine correlates with indicators of glomerular filtration rather than with a test of platelet activation.

Resynchronisation Therapy

Background: Although cardiac resynchronisation therapy (CRT) is an important player in the treatment of heart failure (HF) patients, the proportion of CRT patients with no improvement in either echocardiographic or clinical parameters remains consistently high and accounts for about 30% despite meeting CRT implantation criteria. Furthermore, in patients suffering from HF, renal dysfunction accounts for as many as 30-60%. Accordingly, CRT may improve renal function inducing a systemic haemodynamic benefit leading to increased renal blood flow. Objectives: The aim of the present study was to evaluate the importance of renal function in response to resynchronisation therapy during a 12-month follow-up period. Materials and methods: The study consisted of 46 HF patients qualified for implantation of cardiac resynchronisation therapy defibrillator (CRT-D). A CRT responder is defined as a person without chronic HF exacerbations during observation whose physical efficiency has improved owing to New York Heart Association (NYHA) class improvement ≥1. Results: A statistically significant difference was noted between responders and non-responders regarding creatinine level at the 3rd month (p=0.04) and, particularly, at the 12th month (p=0.02) of follow-up (100±23 vs 139±78 μmol/l). Moreover, there was a remarkable difference between both study groups with regard to GFR CKD-EPI (glomerular filtration rate (GFR) assessed using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula) at the 6th (p=0.03) and 12th month (p=0.01) of follow-up. The reference values for initial creatinine concentrations (101 μmol/l) as well as GFR CKD-EPI (63 ml/min/1.73m2 ) were empirically evaluated to predict favourable therapeutic CRT response. Conclusions: Predictive value of GFR CKD-EPI and creatinine concentration for a positive response to CRT were found relevant.

RESUMOIntrodução: A Granulomatose de Wegener (GW) é uma vasculite rara e idiopática associada à presença do anticorpo Anticitoplasma de Neutrófilo (ANCA) que acomete, preferencialmente, os pequenos vasos. As manifestações clínicas são diversas, ocorrendo em mais de 90% dos casos, sintomas do trato respiratório. O comprometimento renal é tardio e preditor de mau prognóstico. Sua morbidade a médio e longo prazo inclui insuficiência renal crônica. A probabilidade de sucesso de manutenção da função renal depende da concentração sérica de creatinina ao início do tratamento, o que indica a importância do diagnóstico e terapêutica adequada precoces. Casuística: Relata-se o caso de uma paciente do sexo feminino, 61 anos, portadora de GW com comprometimento renal avançado à apresentação não precedido por sintomas pulmonares esperados. O tratamento imunossupressor associado a plasmaferese permitiu a melhora da função renal da paciente poupando-a de tornar-se dialítica- dependente. Discussão: A paciente iniciou a doença através de insuficiência renal assintomática, com valores de função renal compatíveis com o estágio mais avançado de doença renal crônica, ultrassonografia dos rins sem alterações compatíveis e sem os sintomas respiratórios esperados. Segundo a literatura, a combinação de imunossupressores e plasmaferese associa-se à recuperação renal em três meses com sobrevivência sem necessidade de diálise por 12 meses, no caso relatado, obteve-se tal resultado em 22 dias sem a necessidade de diálise após um ano. Conclusão: Devido ao diagnóstico precoce, o tratamento adequado foi instalado rapidamente proporcionando à paciente um aumento da expectativa e da qualidade de vida, evitando dependência de terapia renal substitutiva.Palavras-Chave: Granulomatose de Wegener, Plasmaferese, Doença renal crônica. ABSTRACTIntroduction: The Wegener's Granulomatosis (WG) is a rare and idiopathic vasculitis associated with the presence of Antineutrophil Cytoplasmic Antibody (ANCA), that affects, preferentially, the small vessels. The clinical manifestations are diverse, occurring in over 90% of cases, symptoms in the respiratory tract. Kidney damage is a late and bad prognostic predictor. Morbidity in the medium and long term includes chronic renal failure. The probability of renal function maintenance success depends on serum creatinine concentration at the beginning of treatment that indicates the importance of early diagnosis and deployment of an appropriate therapy. Case Report: We present a case of a 61-year-old female patient, carrier of GW with advanced renal impairment presentation, not preceded by expected pulmonary symptoms. The immunosuppressive treatment associated with plasmapheresis allowed the improvement of the patient’s renal function, saving her from becoming dialysis-dependent Discussion: The patient developed the disease through asymptomatic renal failure, renal function with values that are compatible with the most advanced stage of chronic kidney disease, ultrasound of the kidneys without compatible changes and without the expected respiratory symptoms. According to the literature, the combination of immunosuppressive drugs and plasmapheresis is associated with renal recovery in three months with survival without dialysis for 12 months. In this case, a result was obtained in 22 days without the need for dialysis after one year. Conclusion: Due to the early diagnosis, appropriate treatment was quickly installed giving the patient increased life expectancy and quality, preventing dependence on renal replacement therapy.Keywords: Wegener’s granulomatosis, Plasmapheresis, Chronic renal failure.

Background:LN is still a severe manifestation of Systemic lupus erythematosus (SLE) and multitarget therapy is needed to control the disease especially in refractory cases.Objectives:To evaluate renal response in SLE patients with glomerulonephritis (GN) treated with Belimumab in real-life setting.Methods:Patients with proteinuria >0.5 g/24 h and/or active sediment at baseline enrolled in a multicentre Italian cohort of SLE patients (BeRLiSS study), treated with monthly iv Belimumab 10 mg/kg plus standard of care were considered in this study. Complete renal response (CRR) was defined as proteinuria <0.5 g/24 h, estimated glomerular filtration rate (eGFR)≥90ml/min/1.73m2 and no rescue therapy. Primary efficacy renal response (PERR) was defined as proteinuria ≤0.7 g/24 h, eGFR ≥60ml/min/1.73m2 and no rescue therapy. Prevalence and predictive factors of CRR and PERR at 12 and 24 months after Belimumab initiation were analyzed by multivariate logistic regression analysis.Results:A total of 91 patients were considered in this study, 79 female, mean age 40.51±9.03 years, mean disease duration 12.18±8.15 years, median follow-up time after Belimumab initiation 22 months. Twenty patients had baseline proteinuria ≥0.5 <1 g/day, 17 ≥1 <2 g/day, 13 ≥2 g/day. Belimumab was started at GN onset in 20 (22%) patients and at the time of a renal flare in all other cases. Seventy-five patients underwent a renal biopsy: 1 class I, 4 class II, 14 class III, 47 class IV and 9 class V. Baseline serum creatinine was 82.44±29.26 umol/L; 15 patients showed eGFR<60ml/min/1.73m2 at baseline. Immunosuppresants were taken by 70 (76.9%) patients: 47 micofenolate, 15 azathioprine and 5 ciclosporine. Sixty patients (65.9%) were on antimalarials. During follow-up 34 (37.4%) patients achieved CRR. Among them 5 (14.7%) patients relapsed and 29 (85.3%) patients maintained remission. Mean time to achieved CRR was 9.71±5.91 months.High levels of baseline proteinuria were a negative independent predictor of CRR and PERR at 6 months (OR 0.044 CI95% 0.006-0.320 p=0.002 and OR 0.232 CI95% 0.091-0.596 p=0.002) and 12 months (OR 0.029 CI95% 0.002-0.556 p=0.019 and OR 0.056 CI95% 0.009-0.327 p=0.001). High levels of baseline creatinine were a negative independent predictor of renal response. Renal response at 6 months was a strong predictive factor of renal response at 12 and 24 months.Conclusion:Belimumab is an effective add-on therapy in the treatment of GN in real-life practice setting.Disclosure of Interests:None declared

Background:The prevalence of loneliness increases with age. The presence of loneliness in older adults has been found to be associated with health problems such as depression, decreased cognitive functioning, increases in systolic blood pressure and increased mortality. The underlying mechanisms of the higher mortality risk are largely unknown.Methods:Meta-analysis to investigate the present evidence for the associations between loneliness and mortality. Cross-sectional studies investigating the associations between loneliness and cardiovascular disease and between loneliness and cortisol in 378 depressed and 132 non-depressed older adults.Results:Loneliness appears to be associated with increased mortality, although when only studies are included that consider depression as a covariate, the association is not significant. Therefore it seems likely that depression plays a mediating role in the higher mortality risk.We did not find a significant association between loneliness and cardiovascular disease. In contrast, loneliness was significantly associated with lower cortisol output and decreased dexamethasone suppression.Discussion:The results and their implications for prevention and treatment will be discussed from a clinical perspective as well as a general health perspective. Is loneliness as potentially dangerous as depression?

Renal Nerve Activity

The kidney is the most highly innervated peripheral organ, and both the excretory and endocrine functions of the kidney are regulated by renal nerve activity. The kidney plays a dominant role in body fluid homeostasis, blood ionic concentration, and pH and thereby contributes importantly to systemic blood pressure control. Early studies suggested that the neural-renal interactions were responsible only for short-term adjustments in renal function, but more recent studies indicate that the renal nerves may be a major contributor to chronic renal defects leading to established hypertension and (or) renal disease. The neural-renal interaction is also of considerable interest as a model to elucidate the interplay between the nervous system and peripheral organs, since there is abundant anatomical and physiological information characterizing the renal nerves. The investigator has easy access to the renal nerves and the neural influence on renal function is directly quantifiable both in vivo and in vitro. In this symposium that was presented at the 1990 annual convention of the Society for Neuroscience in St. Louis, Missouri, three prominent researchers evaluate the most recent progress in understanding the interplay between the nervous system and the kidney and explore how the results of these studies relate to the broader questions concerning the nervous system's interactions.First, Luciano Barajas examines the detailed anatomy of the intrarenal distribution of the efferent and afferent renal nerves along the nephron and vasculature, and he evaluates the physiological role of each of the discrete components of the innervation. His basic science orientation combined with his deep appreciation of the clinical consequence of the failure of neural-renal regulation enhances his discussion of the anatomy. Ulla C. Kopp discusses the role of the renorenal reflex, which alters renal responses following stimulation of the contralateral kidney. She also considers her recent findings that efferent renal nerve activity can directly modify sensory feedback to the spinal cord from the kidney. Finally, J. Michael Wyss examines the functional consequences of neural control of the kidney in health and disease. Although the nervous system has often been considered as only an acute regulator of visceral function, current studies into hypertension and renal disease suggest that neural-renal dysfunction may be an important contributor to chronic diseases.Together, these presentations examine most of the recent advances in the area of neural-renal interactions and point out how these data form a basis for future research into neuronal interactions with all visceral organs. The relative simplicity of the neural-renal interaction makes this system an important model with which to elucidate all neural-peripheral and neural-neural interactions.

Endometrial cancer (EC) is the most common gynecologic malignancy in Sweden and it has various prognostic factors. The LRIG family is a group of three integral surface proteins with a similar domain organization. The study aimed to explore LRIG family as prognostic factor proteins in EC. The initial study cohort included 100 women with EC who were treated at the Department of Women’s and Children’s Health, Karolinska University Hospital Solna, between 2007 and 2012. We assessed the associations between LRIG protein expression and type, grade, and stage of EC, as well as progression-free and overall survival. Immunohistochemistry results revealed that most women in the analytical sample had >50% LRIG1-, LRIG2- and LRIG3-positive cells. A statistically significant association was observed between having a high number of LRIG3-positive cells and superior overall survival (incidence rate ratio = 0.977; 95% confidence interval: 0.958–0.996, p = 0.019). Moreover, positive LRIG3 staining of the cell membrane was associated with reducing in the risk of death (hazard ratio = 0.23; 95% confidence interval: 0.09–0.57). Our results show that LRIG3 expression might be a prognostic factor in EC. The role of LRIG1 and LRIG2 expression remains to be further investigated.

Abstract COVID-19 has resulted in an ongoing global pandemic, which spread largely among people who have had close contact with the infected person. The immunopathology of the SARS-CoV-2 virus includes the production of an excess amount of pro-inflammatory cytokines “a cytokine-storm”. The respiratory system (main), cardiovascular system and the gastrointestinal tract are the most affected body systems during viral infection. It has been found that most of the patients who require admission to hospital are elderly or have chronic underlying diseases. Higher cases of malnutrition and co-morbidities like diabetes mellitus and cardiovascular diseases are reported in elderly patients due to which, the immune system weakens and hence, the response to the virus is diminished in magnitude. A deficiency of micronutrients results in impaired immune responses leading to improper secretion of cytokines, alterations in secretory antibody response and antibody affinity which increases susceptibility to viral infection. The deficiency of various micronutrients in COVID-19 patient can be treated by appropriate nutritional supplements, prescribed after evaluating the patients’ nutritional status. Here we aim to highlight the role of a few particular nutrients namely Vitamin D, Vitamin C, Omega-3 fatty acids, Zinc and Magnesium along with the synergistic roles they play in enhancing immunity and thus, maintaining homeostasis.
