Double Trouble: COVID-19 Infection Exacerbates Sickle Cell Crisis Outcomes in Hospitalized Patients-Insights from National Inpatient Sample 2020.

Background: This study investigated the impact of COVID-19 on patients with sickle cell crisis (SCC) using National Inpatient Sample (NIS) data for the year 2020. Methods: A retrospective cohort analysis was conducted utilizing International Classification of Diseases (ICD-10) codes to identify adults who were admitted with a principal diagnosis of sickle cell crisis. The primary outcomes examined were inpatient mortality, while the secondary outcomes assessed included morbidity, hospital length of stay, and resource utilization. Analyses were conducted with STATA. Multivariate logistic and linear regression analyses were used to adjust for confounding variables. Results: Of 66,415 adult patients with a primary SCC diagnosis, 875 were identified with a secondary diagnosis of COVID-19 infection. Unadjusted mortality rate was higher for SCC patients with COVID-19 (2.28%) compared to those without (0.33%), with an adjusted odds ratio (aOR) of 8.49 (p = 0.001). They also showed increased odds of developing acute respiratory failure (aOR = 2.37, p = 0.003) and acute kidney injury requiring dialysis (aOR = 8.66, p = 0.034). Additionally, these patients had longer hospital stays by an adjusted mean of 3.30 days (p < 0.001) and incurred higher hospitalization charges by an adjusted mean of USD 35,578 (p = 0.005). Conclusions: The SCC patients with COVID-19 presented higher mortality rates, increased morbidity indicators, longer hospital stays, and substantial economic burdens.

The association between adverse cardiovascular outcomes in celiac disease and the role of inflammation: Retrospective analysis using the national inpatient sample.

Celiac disease (CD) is an immune-mediated disease with patients being prone to a proinflammatory state. With recent studies showing an association between adverse cardiovascular events in patients with CD, we aim to further elucidate this relationship. Furthermore, when risk-stratifying patients with cardiovascular disease (CVD), chronic inflammatory conditions such as CD are not included in these calculations. We conducted a retrospective analysis using the National Inpatient Sample database from 2016 to 2019 to investigate the relationship between CD and adverse cardiovascular events. Our secondary endpoints include examining patient demographics, underlying comorbidities, in-hospital mortality, and cost of hospitalization. In addition, we performed a subgroup analysis in the CD cohort to assess if concomitant iron deficiency anemia increased CVD. Our study aims to examine the association between atherosclerosis and inflammation and aims to be a stepping stone for future long-term randomized controlled trials for the incorporation into atherosclerotic CVD risk score stratification.

Aeromonas caviae-Associated Severe Bloody Diarrhea.

Aeromonas species are capable of inducing severe infections in both immunocompetent and immunocompromised individuals. Gastroenteritis is the most common infection associated with Aeromonas species in humans. We report a rare case of Aeromonas caviae severe gastroenteritis and bloody diarrhea that led to the development of sepsis in a 45-year-old female with no history of immunocompromising conditions. This patient required extensive medical support which included blood transfusions and antibiotics. Fortunately, with appropriate diagnostic measures and targeted antibiotic therapy, her symptoms resolved. Aeromonas species are becoming increasingly frequent among the pathogens isolated from patients suffering from gastroenteritis. As such, it is becoming increasingly important for clinicians to consider this pathogen when working up their patients for diarrhea.

Superior vena cava syndrome presenting as chylothorax.

Chylothorax caused by superior vena cava (SVC) syndrome is a rare but potentially life-threatening complication requiring a multidisciplinary diagnosis and management approach. We present a case of a 27-year-old female with end-stage renal disease who developed chylothorax secondary to SVC syndrome caused by venous stenosis from a tunneled hemodialysis (HD) catheter. The patient had a history of ongoing hemodialysis through a tunneled catheter placed in the right internal jugular vein approximately seven months before presentation. She presented with dyspnea, chest pain, and a large left-sided pleural effusion. A multidisciplinary diagnostic workup and management included 2 thoracentesis, pleural fluid studies, serial radiological tests, right and left heart catheterizations, and blood serum studies with flow cytometry. They revealed that SVC stenosis around the hemodialysis catheter was causing the patient's pathology. The patient underwent veno-plasty of the right SVC and brachiocephalic veins and replacement of HD catheter leading to the resolution of the chylothorax and significant improvement in respiratory symptoms. This report will highlight the approach to diagnosing and managing chylothorax and a review of existing medical literature.

Iatrogenic lung hernia, a rare complication of thoracoscopic spinal fusion: A case report and review of literature.

A lung hernia is a rare and potentially severe complication that may occur due to thoracic surgery amongst other etiologies. This case report describes the clinical presentation, imaging findings, and management of a patient who developed an iatrogenic lung hernia after undergoing thoracic fusion surgery at the level of T6-T7. The patient presented with persistent chest pain, shortness of breath, and a nonproductive cough. Initial imaging studies revealed the presence of an abnormality within the pleural space, later confirmed through computed tomography of the chest. This case highlights the importance of considering iatrogenic lung hernia as a potential complication of thoracic fusion surgery and the need for close monitoring and prompt intervention in cases when it occurs.

Septic Shock and Bacteremia Secondary to Herbaspirillum huttiense: A Case Report and Review of Literature.

The Herbaspirillum species are gram-negative bacteria that inhabit soil and water. Infections caused by this pathogen are an uncommon clinical entity. We describe a rare case of septic shock and bacteremia caused by Herbaspirillum huttiense in an immunocompetent adult female. The patient, a 59-year-old female, presented to the hospital with circulatory shock, fever, chills, and cough. Chest x-ray revealed right lower lobe lung consolidation consistent with pneumonia, and blood cultures with a positive concerning gram-negative curved rod which was later identified as H. huttiense. The patient was treated in the ICU for three days with cefepime and vasoactive agents. After improvement and an additional seven days of hospitalization, the patient was discharged home with a five-day course of oral levofloxacin. Although our patient responded well to cefepime and levofloxacin, meropenem and piperacillin-tazobactam were found to be the most commonly used and the most effective antibiotics to treat H. huttiense infections in other reported cases. This is amongst the few reported cases of H. huttiense bacteremia in an immunocompetent individual with pneumonia.

A Review on Clostridioides Difficile Testing and How to Approach Patients With Multiple Negative Tests: A Case Report.

Clostridioides difficile (C. difficile) is an important nosocomial infection that is commonly associated with antibiotic use with pseudomembranous colitis being present in only 13% of cases. Disease severity ranges from asymptomatic carriers to severe complicated disease, based on clinical and laboratory findings. There is no single rapid FDA-approved test to diagnose C. difficile infections (CDI) and diagnosis usually requires a multi-step diagnostic approach. C. difficile testing usually begins with the C. difficile toxin and glutamate dehydrogenase antigen screen (GDH). If testing is negative for either, then nucleic acid amplification testing (NAAT) is done to confirm the diagnosis. Endoscopic evaluation may be required in rare instances when there is a high clinical suspicion of disease with negative testing. Here, we present an interesting case of a patient with multiple negative C. difficile toxin and GDH tests. Given the high index of clinical suspicion of CDI, the patient underwent a colonoscopy which revealed diffuse pseudomembranous colitis. The patient was then appropriately treated with oral vancomycin. We aim to shed light on the different testing modalities available to clinicians and the indications for doing a colonoscopy to delineate between false positive testing and active CDI.

A Rare Case of Splenic Artery Thrombosis Provoked By Medroxyprogesterone Acetate Requiring Splenectomy.

Splenic artery thrombosis is estimated to occur in only 0.016% of hospital admissions. Hormonal contraception is known to have hypercoagulable side effects, but splenic artery thrombosis (SAT) followed by functional autosplenectomy is a very rare side effect. We report a case of a 48-year-old female with persistent SAT provoked by depot medroxyprogesterone acetate (DMPA). She initially presented with severe left lower quadrant abdominal pain, and imaging revealed an extensive thrombus in the splenic artery. She was immediately started on intravenous heparin, and her symptoms improved after a few days, at which point she was discharged on oral apixaban. Three months after discharge, the patient presented with symptoms similar to the initial presentation. Further history revealed that she received an injectable DMPA shot prior to her initial admission. Other possible causes of SAT were ruled out. On imaging, her previous thrombus had increased in size and now filled the entire splenic artery. Therefore, the patient underwent robotic splenectomy with remarkable improvement in her symptoms. This case represents a rare clinical manifestation of a hypercoagulable state induced by DMPA. We review the existing literature to explain the epidemiology, presentation, diagnosis, and treatment of SAT, and incorporate our patient's presentation into the existing literature regarding the effect of contraception in inducing thrombotic events.
