Donor-Derived Cell-Free DNA Assessment in a Predominantly Hispanic/Latino Lung Transplant Population: Single-Center Analysis

Received: 31 March 2025;  Published: 21 July 2025;  doi: 10.21926/obm.transplant.2503254

Abstract

The demographics of lung transplant (LT) recipients show an evolution towards increased minority racial/ethnic representation, thanks to an increased focus on inclusion in LT access, healthcare and outcomes. Herein we assess potential differences in LT allograft health in a predominantly Hispanic/Latino (HL) vs Non-Latino/White (NLW) cohort during surveillance for acute rejection by analyzing the fraction of donor-derived cell-free DNA (dd-cfDNA%), a plasma biomarker of allograft injury. Of 245 LT recipients, media [...]

Checkpoint Inhibition Followed by CAR-T Cell Therapy in Refractory PMLBCL: Immunologic Response and Fertility Preservation in a Young Patient

Received: 22 February 2025;  Published: 18 June 2025;  doi: 10.21926/obm.transplant.2502253

Abstract

Primary mediastinal large B-cell lymphoma (PMLBCL) is an aggressive B-cell malignancy that may exhibit resistance to standard chemoimmunotherapy. Novel immunotherapeutic strategies, including checkpoint inhibitors and chimeric antigen receptor T-cell (CAR-T) therapy, are being explored in cases that are refractory to treatment. We report the case of a 29-year-old patient with refractory PMLBCL who was treated with pembrolizumab as a bridging therapy followed by axicabtagene ciloleucel (CAR-T) after failing R-CHOP a [...]

Modern UNOS Data Reveals Septuagenarians Have Inferior Heart Transplant Survival

Received: 10 November 2024;  Published: 11 June 2025;  doi: 10.21926/obm.transplant.2502252

Abstract

While heart transplantation is increasingly performed in the United States for elderly patients, survival outcomes have primarily been analyzed in single-center studies. The few existing long-term studies have indicated no difference in HTx outcomes between patients ≥70 years and 60-69 years age, but these studies only assessed to 5-years post-transplant and included data from the 1980-90s, introducing significant variance due to poorer outcomes in that era. We analyzed the UNOS database from 1987-2020, stratified [...]

Integrating RNA-Seq Biomarkers and Diagnostic Algorithms to Improve Liver Transplant Outcomes: A Comprehensive Review

Received: 21 February 2025;  Published: 09 June 2025;  doi: 10.21926/obm.transplant.2502251

Abstract

Graft rejection, early allograft dysfunction (EAD), and poor diagnostic accuracy are some of the challenges that still need to be addressed, even though liver transplantation (LT) has the potential to help patients with end-stage liver disease (ESLD) significantly. Traditional procedures, such as liver biopsies and liver function tests (LFTs), often fail to identify abnormalities early and with accuracy. Genomic RNA sequencing (RNA-Seq) has recently emerged as a powerful approach for identifying molecular markers o [...]

Mechanisms of Action of Ready-to-Use Therapies in Hematologic Malignancies: From Clinical Impact to Future Directions

Received: 23 January 2025;  Published: 06 June 2025;  doi: 10.21926/obm.transplant.2502250

Abstract

Off-the-shelf cellular therapies, utilizing allogeneic T cells derived from healthy donors, represent a promising alternative to autologous chimeric antigen receptor T-cell (CAR-T) therapies for the treatment of hematological malignancies such as leukemias and lymphomas. Unlike autologous approaches, which require the patient’s own cell collection, modification, and expansion, off-the-shelf therapies can be prepared in advance, substantially reducing treatment timelines, decreasing costs, and improving global acces [...]

Illness Perceptions and Their Impact on Treatment Adherence among Renal Transplant Patients in the COVID-19 Pandemic

Received: 17 December 2024;  Published: 16 May 2025;  doi: 10.21926/obm.transplant.2502249

Abstract

Although immunosuppressive drugs are essential and effective in improving the health status of renal transplant patients, they also make them more vulnerable to the risk of infection with COVID-19, which has become a significant concern for many patients. Perhaps this is what makes their way of thinking and perception impact their adherence to taking immunosuppressants. Therefore, this study reveals the possibility of an impact of illness perception and some sociodemographic and clinical factors on treatment adhere [...]

What Is the Current Status of Single Lung Transplantation? A Literature Review

Received: 19 September 2024;  Published: 27 April 2025;  doi: 10.21926/obm.transplant.2502248

Abstract

Lung transplantation (LTx) is the gold standard for the surgical treatment of end-stage lung disease. Ongoing discussions persist whether single lung transplantation (SLT) or bilateral lung transplantation (BLT) lead to better patient outcomes and quality of life. This study analyzed 58 peer-reviewed articles from 1990 to 2024, comparing SLT and BLT across several parameters, including indications for transplantation, overall survival, pulmonary hypertension, complications, chronic rejection, functional status, and [...]

Updates in Liver Transplantation for Alcohol-Related Liver Disease

Received: 30 November 2024;  Published: 17 April 2025;  doi: 10.21926/obm.transplant.2502247

Abstract

The prevalence of alcohol use disorder (AUD) and alcohol-related liver disease (ALD) has increased in the last two decades. ALD is currently the most common indication for both waitlist additions and liver transplant (LT) in the United States, including alcohol-associated cirrhosis, alcohol-associated hepatitis (AH), and acute-on-chronic liver failure (ACLF). ALD also has a significant global disease burden. LT in ALD is a complex paradigm that poses both medical and ethical challenges, requiring a multidisciplinar [...]

When Immunity Falls Short: Meningoencephalitis Despite Vaccination - A Case Report

Received: 13 June 2024;  Published: 09 April 2025;  doi: 10.21926/obm.transplant.2502246

Abstract

Varicella-zoster virus (VZV) significantly impacts the central and peripheral nervous systems, particularly in immunocompromised individuals. This case report details a rare presentation of VZV meningoencephalitis in a 42-year-old woman with interstitial lung disease and connective tissue disease undergoing lung transplant evaluation who presented with a thunderclap headache and a new-onset seizure. Despite normal initial MRI findings, further investigation with PCR of the cerebrospinal fluid (CSF) revealed the pre [...]

Poly ε-Caprolactone Scaffolds: Advancements in Bone Regeneration and Grafting

Received: 20 October 2024;  Published: 02 April 2025;  doi: 10.21926/obm.transplant.2502245

Abstract

In orthopedics and oncology, benign and malignant bone lesions pose significant clinical challenges. Malignant tumors, like osteosarcomas and multiple myeloma, pose substantial health dangers and can spread common and mostly non-life-threatening benign lesions, including non-sizing fibromas and unicameral bone cysts. Treatment plans for bone lesions may involve radiation, chemotherapy, and surgical excision, depending on their type. Combining stem cell research, bioactive materials, and advanced scaffold design, cu [...]
