The Evolution of Iron-Related Comorbidities and Hospitalization in Patients with Hemochromatosis: An Analysis of the Nationwide Inpatient Sample.

Hemochromatosis, either hereditary hemochromatosis (HH) or secondary hemochromatosis, consists of the accumulation of iron in the liver, heart, and other organs. It leads to end-organ damage in a proportion of affected subjects. Although liver-related morbidity (cirrhosis and hepatocellular carcinoma [HCC]) and mortality are well established, the frequency of these complications remains controversial. The aim of this study is to examine the rate of hospitalization and the incidence of iron overload-related comorbidities in patients with hemochromatosis between the years of 2002 and 2010. We queried the Nationwide Inpatient Sample (NIS) database from the year 2002 to 2010. We included adults (age ≥18 years) and used the ICD-CM 9 code 275.0x to identify hospitalized patients with a diagnosis of hemochromatosis. Data analysis for this study was generated using SAS software version 9.4. A total of 168,614 hospitalized patients between 2002 and 2010 had a diagnosis of hemochromatosis. The majority were males (57%) with a median age of 54 years (37-68), with a predominance of white patients (63.3%) followed by black (26.8%). The rate of hospitalization among patients with hemochromatosis increased by 79% between the years 2002 and 2010 (34.5/100,000 in 2002 vs 61.4/100,000 in 2010). The main associated diagnoses were diabetes mellitus (20.2%), cardiac disease, including arrhythmias (14%) and cardiomyopathy (dilated 3.8%; peri-, endo-, myocarditis 1.3%), liver cirrhosis (8.6%), HCC (1.6%), and acute liver failure (0.81%). Of note, HCC was associated with cirrhosis in 1188 patients (43% of HCC patients) and male sex (87%). Diagnostic biopsies were performed in 6023 (3.6%) of those patients and liver transplant was performed in 881 (0.5%). In-hospital mortality occurred in 3638 (2.16%) patients. In this large database study, we found a rising trend in hospitalization for hemochromatosis, possibly due to the increased recognition of this entity and billing for the condition. The incidence of cirrhosis in hemochromatosis was found to be similar to other studies (8.6% vs 9%). However, the rate of HCC was lower than previous reports (1.6% vs 2.2%-14.9%), and only 43% of HCC was associated with cirrhosis. This raises important pathophysiologic questions regarding the impact of iron overload in HCC. There has been an increase in the rate of hospitalization for patients with a diagnosis of hemochromatosis. This may be related to an increased recognition of hemochromatosis as the underlying etiology for conditions such as diabetes, cardiomyopathy, cirrhosis, and HCC. Further prospective studies are needed to clarify the burden of liver disease in HH and secondary iron overload.

Metastatic melanoma to the lung cured with lobectomy: A case report.

We herein present the case of a 79-year-old female patient who presents with a single asymptomatic pulmonary nodule, melanocytic in nature, later identified as a remote secondary lesion of a primary cutaneous melanoma that was resected 22 years before presentation. Although quite atypical, the patient underwent resection of the affected pulmonary lobe; follow-up imaging did not reveal any local or distant recurrences.

Proton Pump Inhibitors Use and Increased Risk of Spontaneous Bacterial Peritonitis in Cirrhotic Patients: A Retrospective Cohort Analysis.

Background: Since their introduction in the early 1980s, proton pump inhibitors (PPIs) have been used worldwide for a broad range of indications. Unfortunately, however, PPIs have become overly prescribed by healthcare providers, sometimes in the absence of clear indications. Although PPIs were initially presumed to have an excellent safety profile, emerging studies have shed light on the association between their long-term use and a myriad of side effects, including the possibility of an increased risk of spontaneous bacterial peritonitis (SBP). Data available to date regarding the association between PPI use and SBP development in cirrhotic patients is conflicting. While some observational studies provide no association between PPI use in cirrhotic patients and an increased risk of SBP development, many others support this association. As a result of the conflicting conclusions from case controls, cohorts, and meta-analyses, we aimed to carry out this retrospective cohort analysis of data from cirrhotic patients included in the electronic medical record-based commercial database, EXPLORYS (IMB-WATSON, Cleveland, Ohio). Our aim was to evaluate for a possible association between PPIs use and the risk of SBP development in cirrhotic patients and to compare the prevalence of SBP development between cirrhotic patients who were actively using PPIs and those who were not. Methods: A retrospective cohort analysis with chart review was conducted on patients with cirrhosis who were included in the electronic medical record-based commercial database, EXPLORYS (IMB-WATSON, Cleveland, Ohio). Using this database, records were reviewed between December 2017 and 2020. Included patients were adults aged 30 to 79 years with a Systematized Nomenclature of Medicine-Clinical Terms (SNOMED-CT) diagnosis of liver cirrhosis. Included patients with a SNOMED-CT diagnosis of liver cirrhosis were divided into two groups: the first group included all cirrhotic patients who did not use PPIs and the second group included all cirrhotic patients who were on PPIs at home. Results: In our analysis, SBP occurred in 1.7% (1,860 patients) of the included cirrhotic patients whether they were actively taking PPIs or not. Among the 40,670 cirrhotic patients who were on PPIs at home, 1,350 (3.3%) patients developed SBP. On multivariate analysis, PPI use was the strongest predictor for SBP in cirrhotic patients (odds ratio (OR) = 4.24; 95% confidence interval (CI): 3.83 - 4.7, P value < 0.0001), with cirrhotic patients taking PPIs being 4.24 more likely to develop SBP than those not on PPIs. In addition, PPI use, history of bleeding varices, age, race, and gender were found to be independent predicting factors for SBP, in descending order of importance. Conclusions: Our retrospective cohort analysis has shown that the use of PPIs in patients with liver cirrhosis is an independent predicting risk factor for SBP development. It solidified the argument that cirrhotic patients receiving this form of therapy seem to have a higher risk of developing SBP. In the setting of the emerging evidence that PPIs might impose health risks in cirrhotic patients, further studies are needed to settle the current debate between supporters and opponents of this proposition. In addition, future studies may help clarify the relationship between the occurrence of SBP in cirrhotic patients and the type, dose, and duration of PPIs used. We recommend that unless it is clearly indicated, PPI therapy should be avoided or administered with caution in patients with cirrhosis.

The Role and Efficacy of Vitamin C in Sepsis: A Systematic Review and Meta-Analysis.

Clinical rationale for study: Despite advancements in critical care, the mortality rate of sepsis remains high, with an overall poor prognosis. There is a complex pathophysiology of a lethal cascade of cytokines and inflammatory proteins underlying sepsis. The use of vitamin C can theoretically suppress the inflammatory cascade but remains a questionable practice due to a lack of conclusive evidence. Aims of the study: To appraise the therapeutic role of vitamin C in sepsis. Materials and methods: A systematic review was conducted on PubMed, Embase, and the Central Cochrane Registry. The study included randomized clinical trials (RCTs) with vitamin C as an intervention arm in the septic patient population. For continuous variables, the difference in means (MD) and for discrete variables, the odds ratio (OR) was used. For effect sizes, a confidence interval of 95% was used. A p-value of less than 0.05 was used for statistical significance. The analysis was performed using a random-effects model irrespective of heterogeneity. Heterogeneity was evaluated using the I2 statistic. Results: 23 studies were included with the total sample size of 2712 patients. In patients treated with vitamin C, there was a statistically significant reduction in the mortality: OR = 0.778 (0.635 to 0.954), p = 0.016; the sequential organ failure assessment score (SOFA): MD = −0.749 (−1.115 to −0.383), p < 0.001; and the duration of vasopressor requirement: MD = −1.034 days (−1.622 to −0.445), p = 0.001. No significant difference was found in the hospital or ICU length of stay. Conclusions and clinical implications: Vitamin C treatment regimens were associated with reduced mortality, SOFA score, and vasopressor requirement compared to the control in sepsis. Given its low cost and minimal adverse effects, we strongly encourage further large, randomized trials to establish vitamin C as a standard of care in sepsis management.

Association Between Sarcoidosis and Risk of Venous Thromboembolism: A Retrospective Chart Review.

Introduction Sarcoidosis is a multisystemic disorder of an unclear etiology. It has been postulated that sarcoidosis is a chronic autoimmune inflammation, which may predispose to venous thromboembolism (VTE). Recent studies showed increased VTE events in patients with sarcoidosis and other autoimmune disorders. This multicenter retrospective study aims at determining a possible correlation between VTE and sarcoidosis. Subjects and Method We reviewed charts from a commercial database (Explorys Inc, Cleveland, OH, USA), which is an aggregate of electronic health records from 26 major health care systems. We included patients between 30 and 69 of age. Patients with a condition known to cause a hypercoagulable state were excluded. We calculated the prevalence of VTE in patients with and without a diagnosis of sarcoidosis and compared the results. A multivariate analysis was performed to adjust for gender, race, age, tobacco use, and obesity. Results The overall prevalence of the VTE in patients without sarcoidosis was 1.4% compared to 4.9% in patients with sarcoidosis. Patients with sarcoidosis were more likely to develop VTE (OR: 2.96; 95% CI: 2.84-3.08; p < 0.001). Predictors of VTE in patients with sarcoidosis were gender, age, race, and obesity. Conclusion Our study indicates that sarcoidosis poses a risk of developing VTE. Further prospective studies are needed to shed light on this association and explain the prothrombotic phenotype of sarcoidosis.

Insulin use in type II diabetic patients: a predictive of mortality in covid-19 infection.

INTRODUCTION: Starting December 2019, the world has been devastated by the rapid spread of coronavirus disease 2019 (Covid-19). Many risk factors have been associated with worse outcomes and death from Covid-19 pneumonia including having diabetes mellitus. To date, it is not clear if all group of diabetics share the same risk of complications with COVID-19 infection. This study aims to compare disease severity and mortality rate in insulin users versus non-insulin users. METHODS: In this retrospective case-control study conducted at the largest health care network in New York state, we included adult, diabetic patients admitted from March 2020 to October 2020 with Covid-19 pneumonia. We compared the baseline characteristics in addition to outcomes of diabetic patients on home insulin (cases) and non-insulin user diabetics (controls). In addition, to determine if home insulin use is associated with an increased mortality, we conducted a cox regression analysis. RESULTS: We included 696 patients in the study period with a median age of 57 years, interquartile range [IQR] 51-62, and median body mass index 29.9 (IQR: 26-34.7). The majority (476 [68%]) were males. We identified 227 cases (33%) and 469 controls (67%). More cases than controls were hypertensive (74% vs 67%, p = 0.03), on ACE/ARB (50% vs 42%, p = 0.05), and had a hemoglobin A1c > 8.1 (71% vs 44%, p < 0.001). More cases had AKI (52% vs 38%, p < 0.001), however no significant differences were found in intubation rates (26% vs 24%, p = 0.54), detection of pulmonary embolism (4% vs 6%, p = 0.19) or death rate (15% vs 11%, p = 0.22) comparing cases and controls. In a multivariate analysis, we found that home insulin use was independently associated with increased risk of death: Hazard ratio: 1.92, 95% confidence interval (1.13-3.23). CONCLUSION: We showed herein that diabetic patients on home insulin with COVID-19 pneumonia, have worse outcomes and increased mortality compared to diabetics on oral antihyperglycemic agents. Close monitoring of insulin-dependent type II diabetic patients is needed in the current pandemic.

Predictors of Deep Venous Thrombosis in Hospitalized Patients With Liver Cirrhosis in the US.

Background Patients with liver cirrhosis were previously considered as anticoagulated; thus, their risk of developing venous thromboembolism (VTE) is lower. Recently, several studies showed contradicting results regarding deep venous thrombosis (DVT) occurrence in cirrhotic patients. The aim of this study is to evaluate the prevalence and risk associated with developing DVT in hospitalized cirrhotic patients in a large US population. Methods We queried the commercial database Explorys (IMB Inc., Armonk, New York), an aggregate of electronic health record data from 26 US healthcare systems. After excluding patients under 20 years old, a cohort of patients with a Systematized Nomenclature of Medicine - Clinical Terms of "cirrhosis of the liver" and "inpatient care" between 2015-2019 were identified, and prevalence of DVT was calculated in the exposure and the control groups. Statistical analysis for a multivariable model was performed. Factors adjusted for include gender, race, obesity, hypoalbuminemia, diabetes mellitus, viral hepatitis, and liver malignancy. Results Among 9,990,290 patients who were hospitalized between 2015 and 2019, 157,400 patients had a diagnosis of liver cirrhosis. The prevalence of DVT in hospitalized patients with liver cirrhosis was 3.29% compared to 3.18% in non-cirrhotic patients. Using the multivariate analysis model, DVT was inversely associated with cirrhosis in hospitalized patients [OR: 0.921; p<0.0001] compared to patients without liver cirrhosis. Predictors of developing DVT among patients with cirrhosis were non-Caucasian race, obesity (BMI>30), liver malignancy, hypoalbuminemia, and diabetes mellitus. Cirrhotic patients due to viral hepatitis were less likely to develop DVT [OR: 0.775; p<0.001] compared to non-cirrhotic patients. Conclusion In this database, although the prevalence of DVT in cirrhotic hospitalized patients was slightly higher than in non-cirrhotic patients (3.29% vs. 3.18%, respectively), cirrhosis as an independent factor was associated with less risk of DVT during hospitalization. This poses a question regarding DVT prophylaxis necessity in this group of patients. Further studies are needed to clarify the benefit and risks of DVT prophylaxis in cirrhotic patients.

Spontaneous Pneumothorax: A Tale of Two Unique Cases.

We herein present two cases of spontaneous pneumothorax. The first one is occurring in an elderly female who has an extensive history of smoking and an underlying chronic obstructive lung disease, whereas the second case represents a congenital bleb in a male patient who has no other underlying pulmonary disorder. Both cases presented to our facility with a spontaneous pneumothorax following pulmonary bleb rupture. Both patients underwent thoracoscopic surgery with subsequent partial pleurectomy and pleurodesis.

Primary non-typhoidal Salmonella infection presenting as a splenic abscess in a healthy adolescent male.

Isolated splenic abscess in a previously healthy patient is a rare clinical condition and remains a diagnostic dilemma. Clinical presentation is often non-specific and leads to a delay in diagnosis. Imaging studies help to elucidate the condition. Despite advances in medical diagnostics and therapeutics, splenic abscesses can cause significant morbidity and can be fatal. Although splenectomy was considered the treatment of choice in the past, recent trends have seen a shift towards more conservative management. We present the clinical case of a patient who presented to our emergency room with a chief complaint of left shoulder and left upper quadrant abdominal pain. Abdominal imaging showed an intrasplenic collection suspicious for a hemorrhage or an abscess. Percutaneous drainage was successfully performed, followed by conservative management with intravenous antibiotics. The culture of the fluid drained from the spleen was positive for Salmonella Saintpaul. The patient improved and was discharged. A high degree of clinical suspicion is necessary for early identification of a splenic abscess. Splenectomy can be avoided with the use of interventional radiological drainage.
