Background: Graft-versus-host disease (GVHD) is a recognized complication among individuals undergoing bone marrow transplantation (BMT). There is a requirement for supplementary data regarding the in-patient outcomes of GVHD in individuals who have undergone BMT. Our analysis seeks to assess the healthcare burden and outcomes associated with GVHD in hospitalized patients who have undergone BMT., Method: In this retrospective study, we used data from the National Inpatient Sample (NIS) database spanning from 2016 to 2019. Utilizing ICD-10 codes, we distinguished hospitalizations related to BMT and grouped them into two categories: those with GVHD and those without GVHD. Our areas of focus included in-hospital mortality, length of stay, charges, and associations related to GVHD. Unadjusted odds ratios/coefficients were computed through univariable analysis, followed by adjusted odds ratios (aORs)/coefficients from multivariable analysis that considered potential confounding factors., Results: From 2016 to 2019, data were collected from 13,999 hospitalizations with bone marrow transplants. Among them, 836 had GVHD cases. Patient characteristics showed slight differences in mean age and demographics between the two groups, with GVHD patients having a mean age of 51.61 years and higher percentages of males and whites. Analyzing outcomes, patients with GVHD experienced significantly longer hospital stays (41.4 days vs. 21.3 days) and higher total hospital charges ($824,058 vs. $335,765). Adjusting for confounding factors, GVHD posed a substantial risk. The aOR for mortality in GVHD hospitalizations was 7.20 (95% CI: 5.54-9.36, p < .001). The coefficient for the length of stay was 19.36 days (95% CI: 17.29-21.42, p < .001), and the coefficient for total hospital charges was $453,733 (95% CI: $396,577 to $510,889, p < .001) in GVHD cases. Furthermore, GVHD in patients was associated with elevated risks of various medical conditions. The aORs for sepsis, pneumonia, acute respiratory failure, intubation and mechanical ventilation, Clostridium difficile infection, and acute kidney injury (AKI) in GVHD patients were 2.79 (95% CI: 2.28-3.41, p < .001), 3.30 (95% CI: 2.57-4.24, p < .001), 5.10 (95% CI: 4.01-6.49, p < .001), 4.88 (95% CI: 3.75-6.34, p < .001), 1.45 (95% CI: 1.13-1.86, p = .003), and 3.57 (95% CI: 2.97-4.29, p < .001)., Conclusion: GVHD in individuals undergoing BMT is linked to elevated mortality rates, prolonged hospitalization, and higher healthcare costs. Moreover, they face a significantly increased risk of developing complications, such as sepsis, pneumonia, acute respiratory failure, C. difficile infection, and AKI. These results underscore the critical need for vigilant monitoring and effective GVHD management to improve patient outcomes and reduce the complications associated with BMT. Nevertheless, further prospective studies are essential to obtain a more profound understanding and a comprehensive assessment of outcomes in these hospitalized patients., (© 2024 The Author(s).

Background: Castleman disease (CD), also known as angiofollicular lymph node hyperplasia or large lymph node hyperplasia, is a rare medical condition. Despite its rarity, it exhibits diverse clinical presentations and outcomes, which pose challenges for comprehensive understanding and management. This study aims to shed light on the demographics, associations, and outcomes of CD by conducting a retrospective analysis., Methods: The National Inpatient Sample (US) was used to identify patients with the diagnosis of Castleman disease using ICD-10 diagnosis code D47.Z2, during the years 2016-2019. Data was collected on demographics, associated diagnoses, treatments and outcomes. Data analysis was performed using STATA Version 17, College Station, TX: Stata Corp LLC., Results: Our study identified 791 hospitalizations involving adult CD patients. The mean age of these patients was 52.4 years, with a male predominance (56.1%). Whites comprised the largest racial group affected (50.1%). Most patients were covered by Medicare (39.6%). The majority received treatment in urban teaching hospitals (84.0%) and large-bed size facilities (62.5%). In-hospital mortality was low at 2.8%, with an average length of stay of 7.5 days and average total charges of $109,308. Common associations included acute kidney injury (27.0%), congestive heart failure (17.1%), sepsis (16.4%), and acute respiratory failure (12.6%). Hematological and lymphatic associations featured anemia (47.5%), thrombocytopenia (12.2%), and other conditions. Red blood cell transfusions were administered to 11.1% of patients., Conclusion: This study contributes valuable insights into CD, a rare and clinically heterogeneous disease. It underscores the importance of recognizing its associations and complications. Additionally, it highlights the need for further research and improved diagnostic and treatment guidelines to address the complexity of this condition., (© 2023.

Background: Upper gastrointestinal hemorrhage (UGIH) and lower gastrointestinal hemorrhage (LGIH) are 2 of the most common reasons for hospital admissions across the United States. The 30-day readmission after index admission poses a major burden on the health care infrastructure, and thus, it is important to assess the causes of 30-day readmission for patients with UGIH and LGIH., Methods: The study cohort was derived from the 2013 National Readmission Database. International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) Volume 3 diagnosis codes were utilized to identify UGIH and LGIH patients from this data set. Patients who were readmitted to the hospital within 30 days within the same calendar year were further analyzed. Categorical variables and continuous variables were assessed by the χ test and the student t test, respectively. The independent predictors of unplanned 30-day readmissions were recognized by multivariate logistic regression, adjusting for stratified cluster design of National Readmission Database. SAS 9.4 (SAS Institute Inc., Cary, NC) was used for data analysis., Results: The number of index admissions identified from the National Readmission Data 2013 were 82,290 for UGIH and 133,114 for LGIH. All-cause 30-day readmission rate for UGIH versus LGIH was 14.6% (readmitted N=12,046; 56.64% age 65 y and above) versus 14.4% (readmitted N=19,128; 70.21% age 65 y and above and 49.61% men). Gastrointestinal causes were most common (33.9% vs. 39.6%), followed by cardiac (13.3% vs. 15.3%), infectious (10.4% vs. 9.1%), and respiratory causes (7.8% vs. 7.1%) for 30-day readmission for UGIH and LGIH. Significant predictors of increased 30-day readmission (odds ratio, 95% confidence interval, P-value) included metastatic disease (2.15, 1.75-2.64, P<0.001), discharge against medical advice (1.85, 1.55-2.22, P<0.001), and length of stay >3 days (1.50, 1.38-1.63, P<0.001). Predictors for 30-day readmission for LGIH included metastatic disease (1.75, 1.48-2.06, P<0.001), liver disease (1.59, 1.49-1.71, P<0.001), and drug abuse (1.38, 1.21-1.58, P<0.001)., Conclusions: Most common reason for UGIH and LGIH readmission was related to gastrointestinal disease, followed by cardiac, infectious, and respiratory etiologies. By addressing these etiologies for readmission, it may be possible to reduce adverse outcomes.
