Immunocompromised patients who have a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection pose many clinical and public health challenges. We describe the case of a hematopoietic stem cell transplantation patient with lymphoma who had a protracted illness requiring three consecutive hospital admissions. Whole genome sequencing confirmed two different SARS-CoV-2 clades. Clinical management issues and the unanswered questions arising from this case are discussed.

We conducted a systematic review and meta-analysis to evaluate the outcomes of Allogeneic hematopoietic stem cell transplantation (Allo-HSCT) in the treatment of Shwachman-Diamond syndrome (SDS). A literature search was performed on PubMed, Embase, and Web of Science. After screening 397 articles, 10 studies were included.

Immunotherapy utilizes immune cells to target cancer and improves treatment outcomes with few side effects. Despite the effectiveness of immunotherapy, the limited availability of monocytes, which are essential for the differentiation of antigen-presenting cells, remains a major challenge. In this study, we developed a technique for inducing monocytes from hematopoietic stem and progenitor cells by using a serum-free (SF) medium supplemented with optimal concentrations of serum substitutes and cytokines.

We report the case of a 59-year-old patient with a history of peripheral T-cell lymphoma, not otherwise specified (PTCLNOS) presenting with profuse diarrhea 3 months after completing lymphoma treatment. After exhaustive workup a recurrence of the peripheral T-cell lymphoma in the gastrointestinal tract was diagnosed. Predominant gastrointestinal recurrence is a unique presentation of relapse of PTCL-NOS.

The pursuit of a vaccine against the human cytomegalovirus (HCMV) has been ongoing for more than 50 years. HCMV is the leading infectious cause of birth defects, including damage to the brain, and is a common cause of complications in organ transplantation. The complex biology of HCMV has made vaccine development difficult, but a recent meeting sponsored by the National Institute of Allergy and Infectious Diseases in September of 2023 brought together experts from academia, industry, and federal agencies to discuss progress in the field.

Clonal hematopoiesis (CH) is a condition in which hematopoietic stem cells (HSCs) acquire mutations seen in leukemia. While individuals with CH generally do not show signs of hematologic disease, the condition becomes more common with age and correlates with age-related diseases, especially cardiovascular disease (CVD). JAK2 mutations in HSCs can lead to CH and correlate with atherosclerosis, but the condition has been difficult to study because of challenges modeling the mutant cells at very low frequency.
