Clinical transplantation and tolerance: are we there yet?

Organ transplantation is not only considered as the last resort therapy but also as the treatment of choice for many patients with end-stage organ damage. Recipient-mediated acute or chronic immune response is the main challenge after transplant surgery. Nonspecific suppression of host immune system is currently the only method used to prevent organ rejection. Lifelong immunosuppression will cause significant side effects such as infections, malignancies, chronic kidney disease, hypertension and diabetes. This is more relevant in children who have a longer life expectancy so may receive longer

Increased survival of cirrhotic patients with septic shock.

IntroductionThe overall outcome of septic shock has been recently improved. We sought to determine whether this survival gain extends to the high-risk subgroup of patients with cirrhosis.MethodsCirrhotic patients with septic shock admitted to a medical intensive care unit (ICU) during two consecutive periods (1997-2004 and 2005-2010) were retrospectively studied.ResultsForty-seven and 42 cirrhotic patients presented with septic shock in 1997-2004 and 2005-2010, respectively. The recent period differed from the previous one by implementation of adjuvant treatments of septic shock including albu

Дело о том, что скрытая и литичная инфекция Эпштейна-Барра была направлена на множественный склероз.

Вирус Эпштейн-Барр (EBV) тесно связан с множественным склерозом (MS). Он, вероятно, сыграет причинно-следственную роль в патогенезе MS, возможно, путем инициирования автономного иммунитета с помощью молекулярной имитации, автоантигенного представления или регулирования иммунной дистрибьюции. С другой стороны, имеющиеся данные подтверждают прямую роль ЭБВ в стимулировании деятельности по болезням MS посредством скрытых литических инфекций в циклическом режиме либо в рамках ЦНС, либо на периферии. Мы обращаем особое внимание на недавние иммунологические и вирологические выводы, подтверждающие ро

The role of CD38 in HIV infection.

The widely-expressed molecule CD38 is a single-stranded type II transmembrane glycoprotein that is mainly involved in regulating the differentiation and activation state of the cell. CD38 has broad and complex functions, including enzymatic activity, intercellular signal transduction, cell activation, cytokine production, receptor function and adhesion activity, and it plays an important role in the physiological and pathological processes of many diseases. Many studies have shown that CD38 is related to the occurrence and development of HIV infection, and CD38 may regulate its progression thr

T-cell receptor-based therapy: an innovative therapeutic approach for solid tumors.

T-cell receptor (TCR)-based adoptive therapy employs genetically modified lymphocytes that are directed against specific tumor markers. This therapeutic modality requires a structured and integrated process that involves patient screening (e.g., for HLA-A*02:01 and specific tumor targets), leukapheresis, generation of transduced TCR product, lymphodepletion, and infusion of the TCR-based adoptive therapy. In this review, we summarize the current technology and early clinical development of TCR-based therapy in patients with solid tumors. The challenges of TCR-based therapy include those associ

Incidence, significance, and persistence of human coronavirus infection in hematopoietic stem cell transplant recipients.

Hematopoietic stem cell transplant (HSCT) recipients are at increased risk of respiratory viral infections and their associated complications. Unlike other respiratory viruses, little is known about the clinical significance of human coronavirus infection (HCoV) in this population. We retrospectively identified all HSCT recipients who were transplanted between May 2013 and June 2017 at our institution and characterized the cumulative incidence of post-transplant HCoV infection. Of 678 patients who underwent HSCT during the study period, 112 (17%) developed HCoV infection, making HCoV the fourt

Effectiveness and safety of COVID-19 vaccines in patients with oncological diseases: State-of-the-art.

Although the coronavirus disease 2019 (COVID-19) pandemic was declared to be no longer "a public health emergency of international concern" with its wide range of clinical manifestations and late complications, severe acute respiratory syndrome coronavirus 2 infection proved to be a serious threat, especially to the elderly and patients with comorbidities. Patients with oncologic diseases are vulnerable to severe infection and death. Indeed, patients with oncohematological diseases have a higher risk of severe COVID-19 and impaired post-vaccination immunity. Unfortunately, cancer patients are

GvHD prophylaxis with tacrolimus, sirolimus, and mycophenolate mofetil after reduced intensity conditioning hematopoietic stem cell allogeneic transplantation.

We present the largest prospective real-world experience in 159 patients who received the triple combination of tacrolimus/sirolimus/mycophenolate mofetil after reduced intensity conditioning allogeneic hematopoietic stem cell transplantation (RIC-alloHSCT) from matched-related (MRD), matched-unrelated (MUD) or mismatched-unrelated donors (MMURD). Despite the high-risk and elderly population, non-relapse mortality (NRM) at day +100 and 1 year was 5.1% and 8.6%. Grades 2-4 and 3-4 acute Graft-versus-host disease (GvHD) at day +180 was 30.3% and 13%, respectively. Chronic GvHD at 1 and 3 years w

A year in pharmacology: new drugs approved by the US food and drug administration in 2025.

The US Food and Drug Administration approved 45 new drugs and 4 new cellular and gene therapy products in 2025, that is, a total of 49 new medical therapies. Oncology, hematology/immunotherapy, and cardiovascular/respiratory drugs remain most frequent. Among oncology drugs, there is a trend for targeting ever smaller subtypes of malignancies and/or rarer malignancies. Trends over the past 6 years include steady levels of first-in-indication (about 10%), first-in-class (about 38%), and next-in-class (about 51%) approvals. Along with a large share of approvals in orphan indications (> 50%), fast

High Mortality of HLH in ICU Regardless Etiology or Treatment.

Background: Adult hemophagocytic lymphohistiocytosis (HLH) is highly lethal in the ICU. The diagnostic and therapeutic emergency that HLH represents is compounded by its unknown pathophysiological mechanisms. Here, we report on a large cohort of adult HLH in the ICU (ICU-HLH). We analyzed prognostic factors associated with mortality to define the diagnostic and therapeutic challenges in this specific population. Methods: This retrospective study included adult patients diagnosed with HLH in four ICUs in Marseille, France between 2010 and 2020. Patients who fulfilled the HLH-2004 criteria (≥ 4/

Current trends of infectious complications following hematopoietic stem cell transplantation in a single center.

This study was to analyze the infectious complications after hematopoietic stem cell transplantation (HSCT) according to the recent changes of HSCT. Medical records of 379 adult patients who underwent HSCT consecutively at Catholic HSCT Center from January 2001 to December 2002 were reviewed retrospectively. Allogeneic HSCT accounted for 75.7% (287/379) and autologous HSCT for 24.3% (92/379). During pre-engraftment period, bacterial infection was predominant, and E. coli was still the most common organism. After engraftment, viral infection was predominant.

Micro and nanotechnologies: The little formulations that could.

The first publication of micro- and nanotechnology in medicine was in 1798 with the use of the Cowpox virus by Edward Jenner as an attenuated vaccine against Smallpox. Since then, there has been an explosion of micro- and nanotechnologies for medical applications. The breadth of these micro- and nanotechnologies is discussed in this piece, presenting the date of their first report and their latest progression (e.g., clinical trials, FDA approval). This includes successes such as the recent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines from Pfizer, Moderna, and Janssen (

Control of viral infections by epigenetic-targeted therapy.

Epigenetics is defined as the science that studies the modifications of gene expression that are not owed to mutations or changes in the genetic sequence. Recently, strong evidences are pinpointing toward a solid interplay between such epigenetic alterations and the outcome of human cytomegalovirus (HCMV) infection. Guided by the previous possibly promising experimental trials of human immunodeficiency virus (HIV) epigenetic reprogramming, the latter is paving the road toward two major approaches to control viral gene expression or latency. Reactivating HCMV from the latent phase ("shock and k

Аналитическая проверка множественного пептида для многоантигенного серологического профилирования вируса Эпштейн-Барр по различным клиническим образцам.

Вирус Эпштейн-Барр (ЭБВ) заражает более 95% взрослых и связан с различными результатами: от асимптомной запоздалости до инфекционного мононуклеоза (IM), малигнации и множественного склероза (MS). Обычная серология, основанная на ЭЛИСА, часто ограничивается небольшим количеством растворимых, цельнопротеиновых антигенов и не сохраняет информацию о конкретных линейных районах обнаружения антигенов, которые способствуют общей реакции антител. Множественные пептидные микроархивы устраняют это ограничение, однако их использование в клинической практике требует характеристики их аналитических характе

An Extensive Review on Preclinical and Clinical Trials of Oncolytic Viruses Therapy for Pancreatic Cancer.

Chemotherapy resistance and peculiar tumor microenvironment, which diminish or mitigate the effects of therapies, make pancreatic cancer one of the deadliest malignancies to manage and treat. Advanced immunotherapies are under consideration intending to ameliorate the overall patient survival rate in pancreatic cancer. Oncolytic viruses therapy is a new type of immunotherapy in which a virus after infecting and lysis the cancer cell induces/activates patients' immune response by releasing tumor antigen in the blood. The current review covers the pathways and molecular ablation that take place
