Off-label direct oral anticoagulants dosing in atrial fibrillation and venous thromboembolism is associated with higher mortality.

BACKGROUND: Direct oral anticoagulants (DOAC) off-label use data is lacking. Our study aimed to assess the clinical outcomes in a racially mixed population treated for atrial fibrillation (AF) and venous thromboembolism (VTE). METHODS: We retrospectively evaluated six months of DOAC prescriptions for AF or VTE treatment. Prescriptions were classified as off-label or appropriate following FDA labeling. The off-label group was sub-classified as under or overdosing. RESULTS: Of the 1,087 DOAC prescriptions, 67% were for AF. African Americans and Caucasians were equally represented. There were 171 (16%) inappropriate prescriptions, with 106 (62%), being underdosed. The off-label group had a higher 30-day readmissions risk (OR = 1.69, 95% CI:1.11-2.54, p = 0.012) and 1-year all-cause mortality (OR = 1.90, 95% CI:1.02-3.37, p = 0.032). There was no difference in major bleeding (OR = 1.27, 95% CI:0.63-2.37, p = 0.480) or new thromboembolism (OR = 1.27, 95% CI:0.73-2.13, p = 0.369) between the groups. Underdosing carried a higher risk of new thromboembolism (OR = 3.15, 95% CI:1.09-9.15, p = 0.024). CONCLUSIONS: One in every six patients received off-label DOACs dosing. Off-label use had increased 30-day readmissions and 1-year all-cause mortality. Underdosing was associated with a higher risk of new thromboembolism.

Predictors of venous thromboembolism in patients with COVID-19 in an underserved urban population: A single tertiary center experience.

INTRODUCTION: Venous thromboembolism (VTE) is reported in up to 27% of patients with COVID-19 due to SARS-CoV-2 infection. Dysregulated systemic inflammation and various patient traits are presumed to underlie this anomaly. Optimal VTE prophylaxis in COVID-19 patients has not been established due to a lack of validated models for predicting VTE in this population. Our study aims to address this deficiency by identifying demographic and clinical characteristics of COVID-19 patients associated with increased VTE risk. METHODS: This study is a retrospective analysis of all adult patients (final sample, n = 355) hospitalized with confirmed COVID-19 at Einstein Medical Center Philadelphia between March 1 and April 24, 2020. Demographic and clinical patient data were collected and factors associated with VTE were identified and analyzed using t-tests, multivariable logistic regression, and receiver operating characteristic (ROC) curves. RESULTS: Thirty patients (8.5%) developed VTE. Patients with VTE had significantly higher D-dimer levels on admission (P = 0.045) and peak D-dimer levels (P < 0.0001), in addition to higher rates of vasopressor requirements (P = 0.038), intubation (P = 0.003), and death (P = 0.023). Age (OR 1.042), obstructive sleep apnea (OR 5.107), and need for intubation (OR 3.796) were associated with significantly increased odds of VTE. Peak D-dimer level was a good predictor of VTE (AUC 0.806, P < 0.0001) and a D-dimer cutoff of >6640 ng/mL had high (>70%) sensitivity and specificity for VTE. CONCLUSION: Peak D-dimer level may be the most reliable clinical marker in COVID-19 patients for predicting VTE and future prospective studies should attempt to further validate this.

Association of Pre-Admission Statin Use With Reduced In-Hospital Mortality in COVID-19.

BACKGROUND: Coronavirus disease-19 (COVID-19) infection is associated with an uncontrolled systemic inflammatory response. Statins, given their anti-inflammatory properties, may reduce the associated morbidity and mortality. This study aimed to determine the association between statin use prior to hospitalization and in-hospital mortality in COVID-19 patients. METHODS: In this retrospective study, clinical data were collected from the electronic medical records of patients admitted to the hospital with confirmed COVID-19 infection from March 1, 2020 to April 24, 2020. A multivariate regression analysis was performed to study the association of pre-admission statin use with in-hospital mortality. RESULTS: Of 255 patients, 116 (45.5%) patients were on statins prior to admission and 139 (54.5%) were not. The statin group had a higher proportion of end stage renal disease (ESRD) (13.8% vs. 2.9%, p = 0.001), diabetes mellitus (63.8% vs. 35.2%, p<0.001), hypertension (87.9% vs. 61.1%, p < 0.001) and coronary artery disease (CAD) (33.6% vs. 5%, p < 0.001). On multivariate analysis, we found a statistically significant decrease in the odds of in-hospital mortality in patients on statins before admission (OR 0.14, 95% CI 0.03- 0.61, p = 0.008). In the subgroup analysis, statins were associated with a decrease in mortality in those with CAD (OR 0.02, 95% CI 0.0003-0.92 p = 0.045) and those without CAD (OR 0.05, 95% CI 0.005-0.43, p = 0.007). CONCLUSIONS: Our study suggests that statins are associated with reduced in-hospital mortality among patients with COVID-19, regardless of CAD status. More comprehensive epidemiological and molecular studies are needed to establish the role of statins in COVID-19.

Clinical Characteristics, Respiratory Mechanics, and Outcomes in Critically Ill Individuals With COVID-19 Infection in an Underserved Urban Population.

BACKGROUND: The COVID-19 outbreak in the United States has disproportionately affected Black individuals, but little is known about the factors that underlie this observation. Herein, we describe these associations with mortality in a largely minority underserved population. METHODS: This single-center retrospective observational study included all adult subjects with laboratory-confirmed SARS-Cov-2 treated in our ICU between March 15 and May 10, 2020. RESULTS: 128 critically ill adult subjects were included in the study (median age 68 y [interquartile range 61-76], 45% female, and 64% Black); 124 (97%) required intubation. Eighty (63%) subjects died during their in-patient stay, which did not differ by race/ethnicity. Compared with other racial/ethnic groups, Blacks had a greater proportion of women (52% vs 30%, P = .02) and subjects with hypertension (91% vs 78%, P = .035). Asthma (P = .03) was associated with lower in-patient death, primarily among Black subjects (P = .02). Among Black subjects, increased age (odds ratio 1.06 [95% CI 1.05-1.22] per year), positive fluid balance (odds ratio 1.06 [95% CI 1.01-1.11] per 100 mL), and treatment with tocilizumab (odds ratio 25.0 [95% CI 3.5-180]) were independently associated with in-patient death, while higher platelets (odds ratio 0.65 [95% CI 0.47-0.89] per 50 × 103/mL) and treatment with intermediate dose anticoagulants (odds ratio 0.08 [95% CI 0.02-0.43]) were protective. Among other race/ethnic groups, higher total bilirubin (odds ratio 1.75 [95% CI 0.94-3.25] per 0.2 mg/dL) and higher maximum lactate (odds ratio 1.43 [95% CI 0.96-2.13] per mmol/L) were marginally associated with increased death, while tocilizumab treatment was marginally protective (odds ratio 0.24 [95% CI 0.05-1.25]). During first 72 h of ventilation, those who died had less increase in [Formula: see text] (P = .046) and less reduction in PEEP (P = .01) and [Formula: see text] requirement (P = .002); these patterns did not differ by race/ethnicity. CONCLUSIONS: Black and other race/ethnicity subjects had similar mortality rates due to COVID-19 but differed in factors that were associated with increased risk of death. In both groups, subjects who died were older, had a positive fluid balance, and less improvement in [Formula: see text], PEEP, and [Formula: see text] requirement on ventilation.

The relationship between diabetes and clinical outcomes in COVID-19: a single-center retrospective analysis.

AIMS: Coronavirus disease 19 (COVID-19) has become a pandemic. Diabetic patients tend to have poorer outcomes and more severe disease (Kumar et al. in Diabetes Metab Syndr 14(4):535-545, 2020. https://doi.org/10.1016/j.dsx.2020.04.044 ). However, the vast majority of studies are representative of Asian and Caucasian population and fewer represent an African-American population. METHODS: In this single-center, retrospective observational study, we included all adult patients (> 18 years old) admitted to Einstein Medical Center, Philadelphia, with a diagnosis of COVID-19. Patients were classified according to having a known diagnosis of diabetes mellitus. Demographic and clinical data, comorbidities, outcomes and laboratory findings were obtained. RESULTS: Our sample included a total of 355 patients. 70% were African-American, and 47% had diabetes. Patients with diabetes had higher peak inflammatory markers like CRP 184 (111-258) versus 142 (65-229) p = 0.012 and peak LDH 560 (384-758) versus 499 (324-655) p = 0.017. The need for RRT/HD was significantly higher in patients with diabetes (21% vs 11% p = 0.013) as well as the need for vasopressors (28% vs 18% p = 0.023). Only age was found to be an independent predictor of mortality. We found no significant differences in inpatient mortality p = 0.856, need for RRT/HD p = 0.429, need for intubation p = 1.000 and need for vasopressors p = 0.471 in African-Americans with diabetes when compared to non-African-Americans. CONCLUSIONS: Our study demonstrates that patients with COVID-19 and diabetes tend to have more severe disease and poorer clinical outcomes. African-American patients with diabetes did not differ in outcomes or disease severity when compared to non-African-American patients.

Bacterial infections and patterns of antibiotic use in patients with COVID-19.

Bacterial coinfection is associated with poor outcomes in patients with viral pneumonia, but data on its role in the mortality of patients with coronavirus disease 2019 (COVID-19) is limited. This is a single-center retrospective analysis of 242 patients with confirmed COVID-19 admitted to both intensive care and non-intensive care settings. Bacterial coinfection was determined by the presence of characteristic clinical features and positive culture results. Multivariable logistic regression was used to analyze the association of concomitant bacterial infection with inpatient death after adjusting for demographic factors and comorbidities. Antibiotic use pattern was also determined. Bacterial coinfection was detected in 46 (19%) patients. Genitourinary source was the most frequent, representing 57% of all coinfections. The overall mortality rate was 21%. Concomitant bacterial infections were independently associated with increased inpatient mortality (OR, 5.838; 95% CI, 2.647-12.876). Patients with bacterial coinfection were relatively older (71.35 ± 11.20 vs 64.78 ± 15.23; P = .006). A total of 67% of patients received antibiotic therapy, yet 72% did not have an obvious source of bacterial infection. There was a significantly higher rate of inpatient mortality in patients who received antibiotics compared to those who did not (30% vs 5%; P < .0001). Bacterial coinfection in COVID-19 is associated with increased mortality.

The relationship between coronary artery disease and clinical outcomes in COVID-19: a single-center retrospective analysis.

INTRODUCTION: Recent studies have reported evidence that coronavirus disease 2019 (COVID-19) has disproportionately affected patients with underlying comorbidities. Our study aims to evaluate the impact of both cardiac and noncardiac comorbidities on a high-risk population with COVID-19 infection and coronary artery disease (CAD) compared to those without CAD. METHODS: This is a retrospective study of patients who tested COVID-19 positive via reverse transcriptase-PCR (RT-PCR) assay. We compared the characteristics and outcomes of patients with and without CAD. Population demographics, comorbidities and clinical outcomes were collected and analyzed. Multivariate logistic regression analysis was used to identify factors associated with inpatient mortality. RESULTS: A final sample population of 355 patients was identified, 77 of which had a known diagnosis of coronary artery disease. Our study population had a higher proportion of females, and those with CAD were significantly older. The rates of cardiovascular risk factors including hypertension, diabetes mellitus and chronic kidney disease, as well as heart failure and chronic obstructive pulmonary disease were significantly higher in the CAD population. Lactate dehydrogenase was the only inflammatory marker significantly lower in the CAD group, while troponin and brain natriuretic peptide were significantly higher in this population. Patients with CAD also had significantly higher inpatient mortality (31% vs 20%, P = 0.046) and need for renal replacement therapy (33% vs 11%, P < 0.0001) compared to the non-CAD group. However, only age [odds ratio 1.041 (1.017-1.066), P = 0.001] was significantly associated with mortality in the overall population after adjusting for demographics and comorbidities, while the presence of CAD was not independently associated with mortality. CONCLUSION: Patients with CAD and COVID-19 have higher rates of comorbidities, inpatient mortality and need for renal replacement therapy compared to their non-CAD counterparts. However, CAD in itself was not associated with mortality after adjusting for other covariates, suggesting that other factors may play a larger role in the increased mortality and poor outcomes in these patients.

Association Between Intravenous Fluid Resuscitation and Hospital Mortality in Post Cardiac Arrest Patients: A Retrospective Study.

OBJECTIVE: To assess the role for intravenous fluid (IVF) resuscitation in the postarrest state. Primary outcome was survival to hospital discharge and 30-day mortality. Secondary outcomes were associations with amount of vasopressor use and mechanical ventilation days. DESIGN: Retrospective study design. SETTING: Single-center tertiary hospital in Philadelphia, Pennsylvania. PATIENTS: All patients admitted to the intensive care unit between 2018 and 2019. INTERVENTIONS: Patients were divided into two groups based on amount of IVF received within 24 h <30 mL/kg (restricted) and over 30 mL/kg (liberal). MEASUREMENTS AND MAIN RESULTS: A total of 264 patients were included in the study, with 200 included in the restrictive (<30 mL/kg) group and 64 included in the liberal (>30 mg/kg) group. There was no difference in 30-day mortality between the two groups with 146 (73%) deaths in the restrictive groups and 44 (69%) deaths in the liberal group (P = 0.53). There was also no significant difference between those who survived to hospital discharge in the liberal and restrictive groups on Kaplan-Meier analysis (Log-rank = 1.476 P = 0.224). However, there was a significant difference between restrictive and liberal groups with the duration of mechanical ventilation (4 ±â€Š6 days vs. 6 ±â€Š9 days; P = 0.03) and in the rates of two or more vasopressor use (38% vs. 59%; P = 0.002). End-stage renal disease (ESRD) (OR = 2.39; P = 0.03) and volume of fluids in mL/kg/24 h (OR = 1.025; P < 0.0001) were independently associated with higher vasopressor need. Volume of fluid in mL/kg/24 h (P = 0.01), ESRD (P = 0.015), and chronic obstructive pulmonary disease (P = 0.04) were significantly associated with duration of mechanical ventilation, even after adjusting for demographic factors, comorbidities, and mortality. CONCLUSIONS: A liberal strategy of IVF used in resuscitation after cardiac arrest is not associated with higher mortality. However, it predicts higher vasopressor use and duration of mechanical ventilation.

Characteristics and clinical outcomes of COVID-19 patients in an underserved-inner city population: A single tertiary center cohort.

There is limited information describing the characteristics and clinical outcomes of patients infected with coronavirus disease 2019 (COVID-19) especially those in underserved urban area with minority population in the United States. This is a retrospective single-center study for patients who were admitted with COVID-19 infection. Data collection was from 1 March through 24 April 2020. Demographic, clinical, laboratory, and treatment data were presented using descriptive statistics and frequencies. The χ2 test and multivariate logistic regression were used to determine association of risk factors and clinical outcomes. A total of 242 inpatients were included with a mean age of 66 ± 14.75 (±standard deviation). A total of 50% were female and 70% were African American. Comorbidities included hypertension (74%), diabetes mellitus (49%), and 19% had either COPD or asthma. Older age was associated with higher risk of inpatient death odds ratio (OR): 1.056 (95% confidence interval [CI]: 1.023-1.090; P = .001). Inpatient mortality occurred in 70% who needed mechanical ventilation (OR: 29.51; 95% CI: 13.28-65.60; P < .0001), 58% who required continuous renal replacement therapy/hemodialysis (CRRT/HD) (OR: 6.63; 95% CI: 2.74-16.05; P < .0001), and 69% who needed vasopressors (OR: 30.64; 95% CI: 13.56-69.20; P < .0001). Amongst biomarkers of disease severity, only baseline CRP levels (145 ± 116 mg/L) were associated with mortality OR: 1.008 (95% CI: 1.003-1.012; P = .002). Majority of hospitalized patients had hypertension and diabetes. Older age was an independent risk factor for inpatient mortality. Requirement of mechanical ventilation, vasopressor use, and CRRT/HD was associated significantly with inpatient mortality. Higher baseline CRP was significantly associated with inpatient death.

Angiotensin converting enzyme inhibitors and angiotensin II receptor blockers and outcomes in patients with COVID-19: a systematic review and meta-analysis.

BACKGROUND: The use of angiotensin-converting enzyme inhibitors (ACEI) and angiotensin II receptor blockers (ARB) in patients with coronavirus disease 2019 (COVID-19) given their interaction with the angiotensin-converting enzyme-2 (ACE-2) receptor remains controversial. . OBJECTIVE: To investigate the impact of ACEI/ARB on COVID-19 disease severity and mortality through a systematic review and meta-analysis. METHODS: We searched PubMed and CINAHL databases as well as pre-print servers for studies investigating usage of ACEIs/ARBs in patients with COVID-19 compared to a control group of COVID-19 patients without ACEI/ARB use. COVID-19 related severity of disease, and death were identified as end points. Pooled odds ratios (OR) and their 95% confidence intervals (CI) were calculated using random-effects model. RESULTS: 21 studies were included in the meta-analysis. For mortality with ACEI/ARB use, the pooled odds ratio was 1.29 [0.89-1.87] p = 0.18 with heterogeneity of 91%, while the pooled OR for COVID-19 severity was 0.94 [0.59-1.50] p = 0.81 with heterogeneity of 89% (Figure 2). In combining both mortality and severe disease outcomes, the pooled odds ratio was 1.09 [0.80-1.48] p = 0.58 but with heterogeneity of 92%. EXPERT OPINION: Even on pooled analysis of both un-adjusted data, adjusted data(studies with matched controls) and taking into account factors such as risk of bias of studies via meta regression and sensitivity analyses, the results hold true that ACEI/ARB use is not associated with COVID-19 disease severity or mortality. To look for any potential beneficial effects, randomized controlled trials are needed. CONCLUSION: use of ACEI/ARB was not associated with increased mortality or severe COVID-19.

Anticoagulation and bleeding risk in patients with COVID-19.

BACKGROUND: There is no current standardized approach to anticoagulation in patients with Coronavirus Disease 2019 (COVID-19) while potential bleeding risks remain. Our study characterizes the patterns of anticoagulation use in COVID-19 patients and the risk of related bleeding. METHODS: This is a single center retrospective analysis of 355 adult patients with confirmed diagnosis of COVID-19 from March 1 to May 31, 2020. Chi-square was used to analyze the relationship between degree of anticoagulant dose and bleeding events by site. Multivariable logistic regression was used to look at factors associated with inpatient death. RESULTS: 61% of patients were being treated with prophylactic doses of anticoagulation, while 7% and 29% were being treated with sub-therapeutic and therapeutic anticoagulation (TA) doses respectively. In 44% of patients, we found that the decision to escalate the dose of anticoagulation was based on laboratory values characterizing the severity of COVID-19 such as rising D-dimer levels. There were significantly higher rates of bleeding from non-CNS/non-GI sites (p = 0.039) and from any bleeding site overall (p = 0.019) with TA. TA was associated with significantly higher rates of inpatient death (41.6% vs 15.3% p < 0.0001) compared to those without. All patients who developed CNS hemorrhage died p = 0.011. After multivariable logistic regression, only age OR 1.04 95% CI (1.01 to 1.07) p = 0.008 and therapeutic anticoagulation was associated with inpatient mortality OR 6.16 95% CI (2.96 to 12.83) p ≤ 0.0001. CONCLUSION: The use of TA was significantly associated with increased risk of bleeding. Bleeding in turn exhibited trends towards higher inpatient death among patients with COVID-19. These findings should be interpreted with caution and larger more controlled studies are needed to verify the net effects of anticoagulation in patients with COVID-19.

Characteristics of peripheral blood differential counts in hospitalized patients with COVID-19.

BACKGROUND: A lot remains unknown about the features and laboratory findings that may predict worse outcomes in patients with coronavirus disease 2019 (COVID-19). The aim of this study was to evaluate the difference in complete blood count parameters and differential counts in patients hospitalized with COVID-19 who survived compared to those who died. DESIGN: We performed a single-center retrospective study including 242 patients with confirmed COVID-19. We described the characteristics of the complete blood count parameters in these patients. Mann-Whitney U test was used to compare hematologic parameters of patients who died and those who survived; multivariate logistic regression was used to look for associations with mortality. RESULTS: Patients with COVID-19 who died had significantly lower median absolute monocyte count (AMC) (0.4 vs 0.5, P = .039) and median platelet count (169 vs 213, P = .009) compared to those who survived. Patients who died had a significantly higher neutrophil-to-lymphocyte ratio (6.4 vs 4.5, P = .001). The NLR was positively associated with death (OR = 1.038; 95% CI, 1.003-1.074, P = .031), while AMC was inversely associated with death (OR = 0.200; 95% CI, 0.052-0.761, P = .018). CONCLUSION: Among patients with COVID-19, a lower AMC and higher NLR are associated with higher mortality.

The use of IV vitamin C for patients with COVID-19: a case series.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has affected almost 2.5 million people worldwide with almost 170,000 deaths reported to date. So far, there is scarce evidence for the current treatment options available for COVID-19. Vitamin C has previously been used for treatment of severe sepsis and septic shock. We reviewed the feasibility of using vitamin C in the setting of COVID-19 in a series of patients. METHODS: We sequentially identified a series of patients who were requiring at least 30% of FiO2 or more who received IV vitamin C as part of the COVID-19 treatment and analyzed their demographic and clinical characteristics. We compared inflammatory markers pre and post treatment including D-dimer and ferritin. RESULTS: We identified a total of 17 patients who received IV vitamin C for COVID-19. The inpatient mortality rate in this series was 12% with 17.6% rates of intubation and mechanical ventilation. We noted a significant decrease in inflammatory markers, including ferritin and D-dimer, and a trend to decreasing FiO2 requirements, after vitamin C administration. CONCLUSION: The use of IV vitamin C in patients with moderate to severe COVID-19 disease may be feasible.

Clinical Characteristics and Outcomes of Community- and Hospital-Acquired Acute Kidney Injury with COVID-19 in a US Inner City Hospital System.

INTRODUCTION: Emerging data have described poor clinical outcomes from infection with the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV 2) among African American patients and those from underserved socioeconomic groups. We sought to describe the clinical characteristics and outcomes of acute kidney injury (AKI) in this special population. METHODS: This is a retrospective study conducted in an underserved area with a predominance of African American patients with coronavirus disease 2019 (COVID-19). Descriptive statistics were used to characterize the sample population. The onset of AKI and relation to clinical outcomes were determined. Multivariate logistic regression was used to determine factors associated with AKI. RESULTS: Nearly half (49.3%) of the patients with COVID-19 had AKI. Patients with AKI had a significantly lower baseline estimated glomerular filtration rate (eGFR) and higher FiO2 requirement and D-dimer levels on admission. More subnephrotic proteinuria and microhematuria was seen in these patients, and the majority had a pre-renal urine electrolyte profile. Patients with hospital-acquired AKI (HA-AKI) as opposed to those with community-acquired AKI (CA-AKI) had higher rates of in-hospital death (52 vs. 23%, p = 0.005), need for vasopressors (42 vs. 25%, p = 0.024), and need for intubation (55 vs. 25%, p = 0.006). A history of heart failure was significantly associated with AKI after adjusting for baseline eGFR (OR 3.382, 95% CI 1.121-13.231, p = 0.032). CONCLUSION: We report a high burden of AKI among underserved COVID-19 patients with multiple comorbidities. Those who had HA-AKI had worse clinical outcomes compared to those who with CA-AKI. A history of heart failure is an independent predictor of AKI in patients with COVID-19.

Palliative Care Utilization Among Patients With COVID-19 in an Underserved Population: A Single-Center Retrospective Study.

BACKGROUND: As health-care institutions mobilize resources to address the coronavirus disease 2019 (COVID-19) pandemic, palliative care may potentially be underutilized. It is important to assess the use of palliative care in response to the COVID-19 pandemic. METHODS: This is a retrospective single-center study of patients with COVID-19 diagnosed via reverse transcriptase-polymerase chain reaction assay admitted between March 1, 2020, and April 24, 2020. An analysis of the utilization of palliative care in accordance with patient comorbidities and other characteristics was performed while considering clinical outcomes. Chi-square test was used to determine associations between categorical variables while t-tests were used to compare continuous variables. RESULTS: The overall mortality rate was 21.5% (n = 52), and in 48% (n = 25) of these patients, palliative care was not involved. Fifty-nine percent (n = 24) of those who had palliative consults eventually elected for comfort measures and transitioned to hospice care. Among those classified as having severe COVID-19, only 40% (n = 31) had palliative care involvement. Of these patients with severe COVID-19, 68% (n = 52) died. Patients who got palliative care consults were of older age, had higher rates of intubation, a need for vasopressors, and were dead. CONCLUSION: There was a low utilization rate of palliative care in patients with COVID-19. Conscious utilization of palliative care is needed at the time of COVID-19.

Case of acute hepatic injury and elevated ethanol levels in a non-alcoholic adult.

Blood ethanol concentration is measured using different techniques. Gas chromatography/mass spectrometry is used in forensic laboratories to measure whole blood ethanol levels while enzyme immunoassay is often used in hospitals to measure serum or plasma ethanol levels. Lactic acidosis can theoretically cause false elevation of blood ethanol levels measured through enzymatic assay because this method measures the reduction of nicotinamide adenine dinucleotide (NAD+) to nicotinamide adenine dinucleotide- hydrogen (NADH) via the action of a dehydrogenase. Here, we present a rare incidence of ethanol level elevation in a non-alcoholic adult male secondary to lactic acidosis from a rare form of large B-cell lymphoma with infiltration of the liver.

Plummer-Vinson syndrome: improving outcomes with a multidisciplinary approach.

Plummer-Vinson syndrome is a rare condition associated with dysphagia, iron deficiency, and esophageal webs. Data regarding this condition is limited to mostly case reports and a few small cohort studies. Although most cases have a benign and indolent course, the risk of malignancy warrants long-term surveillance. A multidisciplinary approach among healthcare providers is of the utmost importance in the management of this condition.
