Skin Hypopigmentation in Hematology Disorders.

Hypopigmentation disorders pose significant diagnostic challenges in dermatology, sometimes reflecting underlying hematological conditions. This review explores the clinical presentations related to hypopigmentation in hematological disorders, focusing on vitiligo, morphea, and syndromic albinism. Vitiligo, an autoimmune disorder targeting melanocytes, involves interactions between genetic polymorphisms and immune responses, particularly regarding CD8+ T cells and IFN-γ. Drug-induced vitiligo, notably by immune checkpoint inhibitors and small-molecule targeted anticancer therapies, underscores

COVID-19 signalome: Pathways for SARS-CoV-2 infection and impact on COVID-19 associated comorbidity.

The COVID-19 pandemic has been the focus of research the past two years. The major breakthrough was made by discovering pathways related to SARS-CoV-2 infection through cellular interaction by angiotensin-converting enzyme (ACE2) and cytokine storm. The presence of ACE2 in lungs, intestines, cardiovascular tissues, brain, kidneys, liver, and eyes shows that SARS-CoV-2 may have targeted these organs to further activate intracellular signalling pathways that lead to cytokine release syndrome. It has also been reported that SARS-CoV-2 can hijack coatomer protein-I (COPI) for S protein retrograde

Towards Drug Repurposing in Cancer Cachexia: Potential Targets and Candidates.

As a multifactorial and multiorgan syndrome, cancer cachexia is associated with decreased tolerance to antitumor treatments and increased morbidity and mortality rates. The current approaches for the treatment of this syndrome are not always effective and well established. Drug repurposing or repositioning consists of the investigation of pharmacological components that are already available or in clinical trials for certain diseases and explores if they can be used for new indications. Its advantages comparing to de novo drugs development are the reduced amount of time spent and costs. In thi

Guillain-Barré syndrome in patients with multiple myeloma: three cases report and literature review.

BackgroundMultiple myeloma (MM) with Guillain-Barré syndrome (GBS) is relatively rare, and the specific mechanism is still unclear. The previous infection, surgery, and medication use may have contributed to the occurrence of GBS. The use of bortezomib in patients with MM can easily lead to peripheral neuropathy, which is similar to the symptoms of GBS, making it challenging to diagnose GBS.Cases presentationThree patients with IgA type MM experienced lower limb weakness during treatment. Combined with lumbar puncture, nerve conduction studies, and other tests, the diagnosis was confirmed as G

Total adenosine deaminase cases as an inflammatory biomarker of pleural effusion syndrome.

BACKGROUND: Although inflammatory diseases commonly affect the pleura and pleural space, their mechanisms of action remain unclear. The presence of several mediators emphasizes the concept of pleural inflammation. Adenosine deaminase (ADA) is an inflammatory mediator detected at increased levels in the pleural fluid. AIM: To determine the role of total pleural ADA (P-ADA) levels in the diagnosis of pleural inflammatory diseases. METHODS: 157 patients with inflammatory pleural effusion (exudates, n = 124, 79%) and non-inflammatory pleural effusion (transudates, n = 33, 21%) were included in t

A review on how to do hematology consults during COVID-19 pandemic.

The ongoing COVID-19 pandemic is the most trending and talked topic across the World. From its point of origin in Wuhan, China to clinical laboratory at NIH, a mere six-month-old SARS-CoV-2 virus is keeping the clinicians, and scientists busy at various fronts. However, COVID-19 is an emerging and evolving disease and each day brings in more data, new figures, and findings from the field of clinical practice. The role of hematologists has been increasingly recognized during the current pandemic because of several reasons. Most important of them are the characteristic hematological findings of

The Role of NLRP3, a Star of Excellence in Myeloproliferative Neoplasms.

Nucleotide-binding domain (NOD)-like receptor protein 3 (NLRP3) is the most widely investigated inflammasome member whose overactivation can be a driver of several carcinomas. It is activated in response to different signals and plays an important role in metabolic disorders and inflammatory and autoimmune diseases. NLRP3 belongs to the pattern recognition receptors (PRRs) family, expressed in numerous immune cells, and it plays its primary function in myeloid cells. NLRP3 has a crucial role in myeloproliferative neoplasms (MPNs), considered to be the diseases best studied in the inflammasome

Diagnosis and Treatment of Paraneoplastic Neurologic Syndromes.

Paraneoplastic antibody syndromes result from the anti-tumor antibody response against normal antigens ectopically expressed by tumor cells. Although this antibody response plays an important role in helping clear a nascent or established tumor, the engagement of antigens expressed in healthy tissues can lead to complex clinical syndromes with challenging diagnosis and management. The majority of known paraneoplastic antibody syndromes have been found to affect the central and peripheral nervous system. The present review provides an update on the pathophysiology of paraneoplastic neurologic s

MAIT Cells in the Bone Marrow of Patients with Aplastic Anemia.

Mucosal-associated invariant T cells (MAIT cells) are a subset of T cells with innate, effector-like properties that play an essential role in the immune response to microbial infections. In humans, MAIT cells are detectable in the blood, liver, and lungs, but little is known about the frequency of these cells in the bone marrow. Also, the pathogenic role, if any, of MAIT cells in the development of aplastic anemia, a disease with an exquisite origin in the bone marrow, is currently unknown. We investigated the frequency and clinical relevance of bone marrow MAIT cells in a cohort of 14 patien

Cancer Pain Is Not One-Size-Fits-All: Evolving from Tradition to Precision.

Cancer pain remains a significant challenge in oncology, profoundly affecting patients' quality of life, function, and prognosis. Historically under-recognized and managed with a uniform, opioid-centric approach, cancer pain was often inadequately treated. Advances in pain assessment, multimodal analgesia, and supportive care have improved outcomes, yet traditional algorithms frequently fail to address the complex, heterogeneous nature of cancer pain. Contemporary management is shifting toward precision and personalized medicine, integrating genetic, molecular, and biomarker data with individu

Probiotics and nanoparticle-mediated nutrient delivery in the management of transfusion-supported diseases.

Bone marrow is vital for hematopoiesis, producing blood cells essential for oxygen transport, immune defense, and clotting. However, disorders like leukemia, lymphoma, aplastic anemia, and myelodysplastic syndromes can severely disrupt its function, leading to life-threatening complications. Traditional treatments, including chemotherapy and stem cell transplants, have significantly improved patient outcomes but are often associated with severe side effects and limitations, necessitating the exploration of safer, more targeted therapeutic strategies. Nanotechnology has emerged as a promising a

Gemcitabine and carfilzomib induced thrombotic microangiopathy: eculizumab as a life-saving treatment.

Drug-induced aHUS is rare; however, early diagnosis is vital to reduce morbidity and mortality. With confirmation of the diagnosis, eculizumab appears to be a viable treatment option to suppress the pro-inflammatory surge. Furthermore, adverse side effects of medications such as carfilzomib and gemcitabine should be considered in the appropriate settings.

CAR-T cell therapy: A new dawn in the treatment of autoimmune disease.

Autoimmune diseases (AIDs) are a class of diseases caused by autoimmune intolerance, which can be divided into systemic and organ-specific diseases. AIDs affect approximately 10% of the global population and rank among the leading causes of disability and mortality. At present, immunosuppressive agents are the first choice for the treatment of AIDs. B-cell-targeted therapies-particularly CD20 monoclonal antibodies-have brought new hope for systemic AIDs, yet a subset of patients still respond poorly. As a rapidly developing cellular immunotherapy technology, Chimeric antigen receptor T cell (C

Cardio-cerebral infarction: a narrative review of pathophysiology, treatment challenges, and prognostic implications.

Cardio-cerebral infarction (CCI) is a rare clinical syndrome characterized by the simultaneous or sequential occurrence of acute myocardial infarction (AMI) and acute ischemic stroke (AIS). Despite its complex pathogenesis and more severe prognosis compared to isolated AMI or AIS, no consensus has been established regarding its definition, classification, epidemiology, treatment protocols, or prognostic management. Current research is largely confined to case reports or small case series, and there are no unified diagnostic or treatment guidelines, nor any expert consensus. Consequently, clini

Blood Coagulation and Beyond: Position Paper from the Fourth Maastricht Consensus Conference on Thrombosis.

The Fourth Maastricht Consensus Conference on Thrombosis included the following themes. Theme 1: The "coagulome" as a critical driver of cardiovascular disease. Blood coagulation proteins also play divergent roles in biology and pathophysiology, related to specific organs, including brain, heart, bone marrow, and kidney. Four investigators shared their views on these organ-specific topics. Theme 2: Novel mechanisms of thrombosis. Mechanisms linking factor XII to fibrin, including their structural and physical properties, contribute to thrombosis, which is also affected by variation in microbio
