Abstract
A 64-year-old woman presented with agranulocytosis, anemia, and bacteremia, leading to a diagnosis of T-cell large granular lymphocytic leukemia (T-LGLL). A molecular analysis identified a signal transducer and activator of transcription 3 (STAT3) Y640F variant. Initial treatment with cyclophosphamide and prednisolone did not improve her condition, but serious infections were observed. The patient underwent cord blood transplantation (CBT) after preconditioning with fludarabine, busulfan, and total body irradiation, yielding a STAT3 Y640F variant disappearance, based on allele-specific quantitative polymerase chain reaction (AS-qPCR). In this case, CBT is a promising refractory T-LGLL treatment option, and the STAT3 Y640F variant AS-qPCR is a T-LGLL activity marker.

Efficacy of ruxolitinib in the treatment of relapsed/refractory large granular lymphocytic leukaemia. Br J Haematol 2024. [PMID: 38639192 DOI: 10.1111/bjh.19476] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2024] [Revised: 04/03/2024] [Accepted: 04/07/2024] [Indexed: 04/20/2024]
Abstract
Large granular lymphocytic (LGL) leukaemia is a rare chronic lymphoproliferative disorder characterized by an expansion of cytotoxic T or NK cells. Despite a usually indolent evolution, most patients will require a treatment over the course of the disease because of cytopenia or symptomatic associated autoimmune disorders. First-line treatment is based on immunosuppressive agents, namely cyclophosphamide, methotrexate and ciclosporin. However, relapses are frequent, and there is no consensus on the management of relapsed/refractory patients. The implication of the JAK/STAT pathway in the pathogenesis of this disease has prompted our group to propose treatment with ruxolitinib. A series of 21 patients who received this regimen is reported here. Ten patients (47.6%) were refractory to the three main immunosuppressive drugs at the time of ruxolitinib initiation. Ruxolitinib yielded an overall response rate of 86% (n = 18/21), including 3 complete responses and 15 partial responses. With a median follow-up of 9 months, the median response duration was 4 months. One-year event-free survival and 1-year overall survival were 57% and 83% respectively. Mild side effects were observed. Biological parameters, notably neutropenia and anaemia, improved significantly, and complete molecular responses were evidenced. This study supports ruxolitinib as a valid option for the treatment of relapsed/refractory LGL leukaemia.

Abstract
The purified polysaccharides fraction, DOP-2, was prepared from Dioscorea opposita Thunb (D. opposita). This study combined in vitro and in vivo experiments to comprehensively investigate the index changes in RAW264.7 cells and immunocompromised mice under DOP-2 intervention, aiming to elucidate the potential mechanisms of immunomodulatory effects of DOP-2. DOP-2 (10 ∼ 500 μg/mL) significantly elevated the levels of NO, interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) factors secreted by RAW264.7 cells, and restored the body weight of immunosuppressed mice and improve the degree of injury to the immune organ index, resulting in significant immunomodulatory effects. Notably, DOP-2 promoted the production of short-chain fatty acids (SCFAs) in immunosuppressed mice and modulated the composition of their gut microflora. These findings highlight the potential benefits of DOP-2 therapy in improving immune function and gut health, and will provide a theoretical basis for the application of D. opposita polysaccharides as an immunomodulatory adjuvant.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Caragana sinica (Buc'hoz) Rehd. is a plant widely grown in Yunnan, China, for both medicinal and edible purposes. The "National Compilation of Chinese Herbal Medicine" describes its nature as "slightly temperate and sweet". Caragana sinica is usually medicated with whole herbs, the main function is to replenish the kidneys and stop bleeding. Caragana sinica was used in folk medicine in Chuxiong, Yunnan, to treat deficiency colds, fatigue, fever, cough, hypertension, and other diseases. AIM OF THE STUDY This article investigates the structural characteristics of Caragana sinica polysaccharide (CSP) and explores its immune-regulatory activity and molecular biological mechanisms in cyclophosphamide-induced immunosuppressed mice, as well as its effects on intestinal bacteria. METHODS With the water-extraction and alcohol-precipitation method, Caragana sinica polysaccharide were extracted, obtaining CSP by purification. A variety of methods and techniques have been used to analyze the chemical properties and structural characteristics of CSP. Immunosuppressive mice model was established through intraperitoneal injection of cyclophosphamide (CTX) to study the immune-regulatory effects and mechanisms of CSP. RESULTS The data indicated that CSP is a neutral heteropolysaccharide mainly composed of arabinose and galactose. This article uses immunosuppressive mice induced by cyclophosphamide (CTX) as the model. The results showed that CSP can promote the immune function of CTX treated immunosuppressed mice and regulate the diversity and composition of intestinal microbiota. CSP can increase macrophage phagocytosis, NK cell killing activity, and lymphocyte proliferation activity. It can also repair the index and morphological damage of the thymus and spleen. And by binding to the TLR4 receptor, MyD88 was activated and interacted with TRAF6 to promote the transfer of NF-κB into the nucleus. Thereby promoting cytokine release and increasing the production of IL-1β, IL-6, IL-10, TNF-α, IgA, and IgG in the serum. CSP also effectively alleviated the liver damage caused by CTX through antioxidant activity. Furthermore, CSP can dramatically affect the intestinal microbiota and the body's immunity by boosting the relative presence of Bacteroides and Verrucamicrobiota. CONCLUSIONS Research results indicated that CSP can regulate the immune function of mice, providing a basis for developing CSP as a potential immune modulator and functional food.

Abstract
INTRODUCTION Large granular lymphocytic (LGL) leukemia is a rare lymphoproliferative disorder characterized by an expansion of clonal T or NK lymphocytes. Neutropenia-related infections represent the main clinical manifestation. Even if the disease follows an indolent course, most patients will ultimately need treatment in their lifetime. Interestingly, LGL leukemia is characterized by a high frequency of autoimmune disorders with rheumatoid arthritis being the most frequent. AREAS COVERED This review covers the pathophysiology, clinic-biological features and the advances made in the treatment of LGL leukemia. A special focus will be made on the similarities in the pathophysiology of LGL leukemia and the frequently associated rheumatic disorders. EXPERT OPINION Recent advances in the phenotypic and molecular characterization of LGL clones have uncovered the key role of JAK-STAT signaling in the pathophysiology linking leukemic cells expansion and autoimmunity. The description of the molecular landscape of T- and NK-LGL leukemia and the improved understanding of the associated rheumatic disorders open the way to the development of new targeted therapies effective on both conditions.

Abstract
T-cell large granular lymphocytic leukemia (T-LGLL) is a clonal proliferation of cytotoxic T lymphocytes that can result in severe neutropenia, anemia, and bone marrow failure. Strong evidence from patients and mouse models demonstrate the critical role of interleukin-15 (IL-15) in T-LGLL pathogenesis. BNZ-1 is a pegylated peptide that selectively inhibits the binding of IL-15 and other γc cytokines to their cellular receptor complex, which has demonstrated efficacy in ex vivo T-LGLL cells and transgenic mice in preclinical studies. We conducted a phase 1/2 trial of BNZ-1 in patients with T-LGLL who had hematocytopenias (anemia or neutropenia) and required therapy. Clinical responses were assessed using hematologic parameters (improvement in hematocytopenias) based on response criteria from the Eastern Cooperative Oncology Group 5998 T-LGLL trial. BNZ-1 demonstrated clinical partial responses in 20% of patients with T-LGLL with minimal toxicity and the maximum tolerated dose was not reached. Furthermore, T-LGL leukemic cells showed significantly increased apoptosis in response to BNZ-1 treatment as early as day 2, including in clinical nonresponders, with changes that remained statistically different from baseline throughout treatment (P < .005). We report first-in-human proof that T-LGL leukemic cells are dependent on IL-15 and that intervention with IL-15 inhibition with BNZ-1 in patients with T-LGLL shows therapeutic effects, which carries important implications for the understanding of the pathogenesis of this disease. This trial was registered at www.clinicaltrials.gov as #NCT03239392.

Abstract
Background Cyclophosphamide (CP), commonly used as an anticarcinogenic drug, has the potential to induce detrimental effects on multiple tissues, including the liver. Asprosin, which is a glucogenic adipokine, induces the liver to secrete glucose, thus contributing to the maintenance of homeostasis. This study aims to investigate the immunoreactivity of asprosin in the liver tissue of rats exposed to CP administration, as well as the changes in its levels due to the supplementation of Vitamin D (Vit D). Materials and methods Four experimental groups were formed, including control, Vit D (200 IU/kg), CP (200 mg/kg), and Vit D+ CP. Histopathological analysis was carried out by employing staining methods on liver tissues. These techniques encompassed the application of hematoxylin-eosin (H&E), Masson's trichrome, and periodic acid Schiff (PAS). Through the application of spectrophotometric methods, concentrations of malondialdehyde (MDA), total antioxidant status (TAS), total oxidant status (TOS), and asprosin were determined. Furthermore, apoptotic cells were identified by the terminal deoxynucleotidyl transferase (TdT) dUTP nick-end labeling (TUNEL) method, and the asprosin immunoreactivity was determined by immunohistochemistry. Results Under light microscope examination, the histopathological damage was found to be more notable in the CP group compared to the control group. Moreover, a decrease was observed in serum and tissue asprosin levels, while an increase was noted in the count of apoptotic cells, along with elevated MDA and TOS levels. However, in the CP+Vit D group, Vit D administration alleviated histopathological damage. Notably, there were significant increases in TAS and asprosin levels, accompanied by reductions in both MDA and TOS levels. Conclusions The effect of CP on liver tissue was observed to result in damage and a reduction in asprosin levels. Vit D supplementation revealed elevated asprosin levels and a distinct protective effect on the tissue. Considering the association between asprosin and liver injury induced by CP, further research is needed to elucidate the mechanisms that underlie the effect of asprosin on tissues. When combined with Vit D, asprosin holds promise for potential clinical applications as a therapeutic target.

Abstract
Large Granular Lymphocyte (LGL) Leukemia is a rare, heterogeneous even more that once thought, chronic lymphoproliferative disorder characterized by the clonal expansion of T- or NK-LGLs that requires appropriate immunophenotypic and molecular characterization. As in many other hematological conditions, genomic features are taking research efforts one step further and are also becoming instrumental in refining discrete subsets of LGL disorders. In particular, STAT3 and STAT5B mutations may be harbored in leukemic cells and their presence has been linked to diagnosis of LGL disorders. On clinical grounds, a correlation has been established in CD8+ T-LGLL patients between STAT3 mutations and clinical features, in particular neutropenia that favors the onset of severe infections. Revisiting biological aspects, clinical features as well as current and predictable emerging treatments of these disorders, we will herein discuss why appropriate dissection of different disease variants is needed to better manage patients with LGL disorders.

Abstract
This study aimed to investigate the immunoenhancement effects of low molecular weight peptides (SCHPs-F1) from red shrimp (Solenocera crassicornis) head against cyclophosphamide (CTX)-induced immunosuppressed mice. ICR mice were intraperitoneally injected with 80 mg/kg CTX for 5 consecutive days to establish the immunosuppressive model and then intragastrically administered with SCHPs-F1 (100 mg/kg, 200 mg/kg, and 400 mg/kg) to investigate its improving effect on immunosuppressed mice and explore its potential mechanism using Western blot. SCHPs-F1 could effectively improve the spleen and thymus index, promoting serum cytokines and immunoglobulins production and upregulating the proliferative activity of splenic lymphocytes and peritoneal macrophages of the CTX-treated mice. Moreover, SCHPs-F1 could significantly promote the expression levels of related proteins in the NF-κB and MAPK pathways in the spleen tissues. Overall, the results suggested that SCHPs-F1 could effectively ameliorate the immune deficiency caused by CTX and had the potential to explore as an immunomodulator in functional foods or dietary supplements.

Alruhaimi RS. Protective effect of arbutin against cyclophosphamide-induced oxidative stress, inflammation, and hepatotoxicity via Nrf2/HO-1 pathway in rats. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2023; 30:68101-68110.

Abstract
Cyclophosphamide (CP) is a potent anticancer drug widely employed in chemotherapy against various types of cancer. However, CP leads to toxicity to non-targeted organs, including the liver and this limits its clinical use. This study explored the role of arbutin (ARB) against CP-mediated oxidative and inflammatory reactions and hepatotoxicity. Rats were administered ARB (25 and 50 mg/kg) for 14 days and CP (150 mg/kg). CP triggered liver tissue injury with marked increase in serum AST, ALT, ALP, and bilirubin, and hepatic malondialdehyde (MDA) and nitric oxide (NO) coupled with diminution of GSH, SOD, catalase, and GPx. Liver NF-kB p65, NOS, IL-6, TNF-α, Bax and caspase-3 were upregulated by CP injection and IL-10 and Bcl-2 were decreased. ARB prevented liver injury, suppressed MDA, NO, NF-kB p65, inflammatory markers, Bax and caspase-3 in CP-treated rats. ARB restored antioxidants, IL-10 and Bcl-2, and enhanced Nrf2 and hemeoxygenase-1 (HO) both gene and protein in the liver of rats. In conclusion, these results pinpointed the protective role of ARB on oxidative and inflammatory reactions, apoptosis, and hepatotoxicity in rats. This hepatoprotective activity was linked to the ability of ARB to modulate Nrf2/HO-1 pathway.

Abstract
Large granular lymphocyte leukemia (LGLL) is a chronic lymphoproliferative disorder characterized by the proliferation of T or NK cytotoxic cells in the peripheral blood, the spleen and the bone marrow. Neutropenia leading to recurrent infections represents the main manifestation of LGLL. One specificity of LGLL is its frequent association with auto-immune disorders, among them first and foremost rheumatoid arthritis, and other hematologic diseases, including pure red cell aplasia and bone marrow failure. The large spectrum of manifestations and the classical indolent course contribute to the diagnosis difficulties and the frequency of underdiagnosed cases. Of importance, the dysimmune manifestations disappear with the treatment of LGLL as the blood cell counts normalize, giving a strong argument for a pathological link between the two entities. The therapeutic challenge results from the high rate of relapses following the first line of immunosuppressive drugs. New targeted agents, some of which are currently approved in autoimmune diseases, appear to be relevant therapeutic strategies to treat LGLL, by targeting key activated pathways involved in the pathogenesis of the disease, including JAK-STAT signaling.

Abstract
Ischemia/reperfusion injury (IRI) is a common cause of kidney damage, characterized by oxidative stress and inflammation. In this study, we investigated the potential protective effects of IAXO-102, a chemical compound, on experimentally induced IRI in male rats. The bilateral renal IRI model was used, with 24 adult male rats randomly divided into four groups (N=6): sham group (laparotomy without IRI induction), control group (laparotomy plus bilateral IRI for 30 minutes followed by 2 hours of reperfusion), vehicle group (same as control but pre-injected with the vehicle), and treatment group (similar to control but pre-injected with IAXO-102). We measured several biomarkers involved in IRI pathophysiology using enzyme-linked immunosorbent assay (ELISA), including High mobility group box1 (HMGB1), nuclear factor kappa b-p65 (NF-κB p65), interleukin beta-1 (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), 8-isoprostane, Bcl-2 associated X protein (BAX), heat shock protein 27 (HSP27), and Bcl-2. Statistical analysis was performed using one-way ANOVA and Tukey post hoc tests. Our results showed that IAXO-102 significantly improved kidney function, reduced histological alterations, and decreased the inflammatory response (IL-1, IL-6, and TNF) caused by IRI. IAXO-102 also decreased apoptosis by reducing pro-apoptotic Bax and increasing anti-apoptotic Bcl-2 without impacting HSP27. In conclusion, our findings suggest that IAXO-102 had a significant protective effect against IRI damage in the kidneys.

Abstract
Canine chronic large granular lymphocyte (LGL) leukaemia is commonly characterised by moderate to marked lymphocytosis but not neutropaenia. In humans, LGL leukaemia is often associated with autoimmune disorders, including immune-mediated cytopaenias (mainly neutropaenia). This presentation is rare in dogs. The aim of this retrospective study was to describe the clinical characteristics, treatments, and outcomes of dogs with chronic LGL leukaemia with suspected immune-mediated cytopaenia. Six dogs with a median age of 4.5 years (range 2-8 years) were included in the study. The most common presenting signs were pyrexia and lethargy. All dogs had severe neutropaenia (median neutrophil count 0.07 × 109/L), three had thrombocytopaenia (median platelet count 66 × 109/L), and one had anaemia (HCT 0.32 L/L). In all dogs, bone marrow cytology revealed infiltration of granular T lymphocytes; PARR analysis confirmed clonality in four, and bone marrow flow cytometry identified CD3+ CD8+ neoplastic cells in two cases. All patients received systemic chemotherapy, and the cytopaenias resolved after 1-19 weeks. Two dogs were euthanised 133 and 322 days after diagnosis, two were lost to follow-up after 224 and 357 days, and two were alive at 546 and 721 days. A subset of LGL leukaemia in dogs is associated with immune-mediated cytopaenia and has a unique clinical presentation.

Abstract
Large granular lymphocyte leukemia is a rare chronic lymphoproliferative disease of cytotoxic lymphocytes. The diagnosis, according to the WHO, is based on a persistent (>6 months) increase in the number of LGL cells in the peripheral blood without an identifiable cause. A further distinction is made between T-LGL and NK-LGL leukemia. The molecular sign of LGL leukemia is the mutation of STAT3 and other genes associated with the JAK/STAT pathway. The most common clinical features are neutropenia, anemia, and thrombocytopenia, and it is often associated with various autoimmune conditions. It usually has an indolent course. Due to the rarity of the disease, no specific treatment has yet been identified. Immunosuppressive therapy is used and may allow for disease control and long-term survival, but not eradication of the leukemic clone. Here, we discuss the clinical presentation, diagnostic challenges, pathophysiology, and different treatment options available for alpha/beta T-LGL leukemia, which is the most common disease (85%), in order to better understand and manage this often misunderstood disease.

Abstract
Complementary and alternative medicine (CAM) supplements are widely used by cancer patients. Dietary supplements, vitamins and minerals, herbal remedies, and antioxidants are especially popular. In a systematic literature review, 37 studies, each including more than 1000 participants, on CAM, dietary supplement, and vitamin use among cancer patients were identified. Accordingly, cancer patients use antioxidants such as vitamin C (from 2.6% (United Kingdom) to 41.6% (United States)) and vitamin E (from 2.9% (China) to 48% (United States)). Dietary supplements and vitamins are taken for different reasons, but often during conventional cancer treatment involving chemotherapy or radiotherapy and in a self-decided manner without seeking medical advice from healthcare professionals. Drug-drug interactions with dietary supplements or vitamins involving multiple signaling pathways are well described. Since most of the anticancer drugs generate reactive oxygen species (ROS), an adaptive stress response of healthy and malignant cells, mainly driven by the Nrf-2-Keap I network, can be observed. On the one hand, healthy cells should be protected from ROS-overproducing chemotherapy and radiotherapy; on the other hand, ROS production in cancer cells is a "desirable side effect" during anticancer drug treatment. We here describe the paradoxical use of antioxidants and supplements during cancer therapy, possible interactions with anticancer drugs, and the involvement of the Nrf-2 transcription factor.

Abstract
Liver injury is among the adverse effects of the chemotherapeutic agent cyclophosphamide (CP). This study investigated the protective role of the flavone apigenin (API) against CP-induced liver damage, pointing to the involvement of Nrf2/HO-1 signaling. Rats were treated with API (20 and 40 mg/kg) for 15 days and received CP (150 mg/kg) on day 16. CP caused liver damage manifested by an elevation of transaminases, alkaline phosphatase (ALP), and lactate dehydrogenase (LDH), and histological alterations, including granular vacuolation, mononuclear cell infiltration, and hydropic changes. Hepatic reactive oxygen species (ROS), malondialdehyde (MDA), and nitric oxide (NO) were increased and glutathione (GSH) and antioxidant enzymes were decreased in CP-administered rats. CP upregulated the inflammatory markers NF-κB p65, TNF-α, IL-6, and iNOS, along with the pro-apoptotic Bax and caspase-3. Pre-treatment with API ameliorated circulating transaminases, ALP, and LDH, and prevented histopathological changes in CP-intoxicated rats. API suppressed ROS, MDA, NO, NF-κB p65, iNOS, inflammatory cytokines, oxidative DNA damage, Bax, and caspase-3 in CP-intoxicated rats. In addition, API enhanced hepatic antioxidants and Bcl-2 and boosted the Nrf2 and HO-1 mRNA abundance and protein. In conclusion, API is effective in preventing CP hepatotoxicity by attenuating oxidative stress, the inflammatory response, and apoptosis. The hepatoprotective efficacy of API was associated with the upregulation of Nrf2/HO-1 signaling.

Abstract
AIMS Cyclophosphamide (Cyclo) is an immunosuppressive and antineoplastic agent. The clinical use of Cyclo is limited by significant hepatotoxicity. Piracetam (Pira) is used to improve cognitive function. Pira possesses diverse physiological functions; however, the exact mechanisms of its activity are still non-elucidated. MAIN METHODS Forty rats were allocated in four groups. 1st group comprised normal rats; the remaining groups received single Cyclo dose (200 mg/kg/i.p.) on the experiment's 15th day. 2nd group comprised Cyclo-control rats. 3rd & 4th groups received Pira (100 & 300 mg/kg body weight) for 15 days. KEY FINDINGS Cyclo administration resulted in deterioration of serum liver function tests and elevation of hepatic tissue concentration of P53, Nf-kβ, apoptosis-inducing factor-1, NLRP3 inflammasome, Bax; gene expression of receptor-induced protein-1 along with reduction of hepatic Bcl-2 concentration. Bax/Bcl-2 ratio headed for apoptosis. Cyclo administration also resulted in a severe deterioration of the hepatic histopathological picture and significant immunohistochemical expression of caspase-3, tumor necrosis factor-alpha (TNF-α) and Cyclooxygenase-2 (COX-2) in hepatic tissues versus the normal group. Pira significantly improved all the aforementioned parameters, reallocating the Bax/Bcl-2 ratio to anti-apoptosis. Moreover, Pira treatment amended Cyclo-induced histopathological abnormalities and significantly reduced caspase-3, TNF-α plus COX-2 immunoreactivity in hepatic tissues. SIGNIFICANCE The present work is the first to link Cyclo-induced hepatotoxicity to the activation of caspase-independent apoptosis (necroptosis), pyroptosis and caspase-dependent apoptosis signaling pathways. Pira treatment significantly ameliorated Cyclo-induced hepatotoxicity mainly via the amendment of necroptotic, pyroptotic and caspase-dependent apoptotic changes along with the histopathological deformities in rats' hepatic tissues.

Abstract
Cyclophosphamide (CP)-induced lung toxicity is a remaining obstacle against the beneficial use of this chemotherapeutic agent. More considerations were given to the role of Alogliptin (ALO) in ameliorating CP-induced toxicities in many tissues. We designed this study to clarify the protective potential of ALO against CP-induced lung toxicity in rats. ALO was administered for 7 days. Single-dose CP was injected on the 2nd day (200 mg/kg: i.p.) to induce lung toxicity. Rats were divided into four groups: control, ALO-treated, CP-treated and ALO + CP-treated group. Leucocytic count, total proteins, LDH activity, TNF-α, and IL-6 were estimated in the bronchoalveolar lavage fluid (BALF). The oxidative/antioxidants (MDA, Nrf2, TAO and GSH), inflammatory (NFκB), fibrotic (TGF-β1) and apoptotic (PI3K/Akt/FoxO1) markers in pulmonary homogenates were biochemically evaluated. Rat lung sections were examined histologically (light and electron microscopic examination) and immunohistochemically (for iNOS and CD68 positive alveolar macrophages). CP significantly increased oxidative stress, inflammation, fibrosis, and apoptosis markers as well as deteriorated the histopathological pulmonary architecture. These hazardous effects were significantly ameliorated by ALO treatment. ALO protected against CP-induced lung toxicity by mitigating the oxidative, inflammatory and fibrotic impacts making it a promising pharmacological therapy for mitigating CP-induced lung toxicity.

Abstract
T cell large granular lymphocytic leukemia (T-LGLL) is a rare lymphoproliferative disorder of mature, clonally expanded T cells, where somatic-activating STAT3 mutations are common. Although T-LGLL has been described as a chronic T cell response to an antigen, the function of the non-leukemic immune system in this response is largely uncharacterized. Here, by utilizing single-cell RNA and T cell receptor profiling (scRNA+TCRαβ-seq), we show that irrespective of STAT3 mutation status, T-LGLL clonotypes are more cytotoxic and exhausted than healthy reactive clonotypes. In addition, T-LGLL clonotypes show more active cell communication than reactive clones with non-leukemic immune cells via costimulatory cell-cell interactions, monocyte-secreted proinflammatory cytokines, and T-LGLL-clone-secreted IFNγ. Besides the leukemic repertoire, the non-leukemic T cell repertoire in T-LGLL is also more mature, cytotoxic, and clonally restricted than in other cancers and autoimmune disorders. Finally, 72% of the leukemic T-LGLL clonotypes share T cell receptor similarities with their non-leukemic repertoire, linking the leukemic and non-leukemic repertoires together via possible common target antigens. Our results provide a rationale to prioritize therapies that target the entire immune repertoire and not only the T-LGLL clonotype.

Abstract
PURPOSE OF REVIEW This manuscript aims at updating the knowledge on the clinico-biological characteristics, pathogenesis, and the diagnostic challenges of T-LGLL and CLPD-NK disorders and reviews the advances in the management and treatment of these patients. RECENT FINDINGS It has been shown that clonal large granular lymphocyte (LGL) expansions arise from chronic antigenic stimulation, leading to resistance to apoptosis. All the above findings have facilitated the diagnosis of LGLL and provided insights in the pathogenesis of the disease. At present, there is no standard first-line therapy for the disease. Immunosuppressive agents are the treatment routinely used in clinical practice. However, these agents have a limited capacity to eradicate the LGL clone and induce long-lasting remission. Advances in the knowledge of pathogenesis have made it possible to explore new therapeutic targets with promising results. Since LGLL is a rare disease, international efforts are needed to carry on prospective clinical trials with new potentially active drugs that could include a large number of patients.

Abstract
Large granular lymphocyte leukemia (LGLL) is a rare lymphoproliferative disorder characterized by the clonal expansion of cytotoxic T-LGL or NK cells. Chronic isolated neutropenia represents the clinical hallmark of the disease, being present in up to 80% of cases. New advances were made in the biological characterization of neutropenia in these patients, in particular STAT3 mutations and a discrete immunophenotype are now recognized as relevant features. Nevertheless, the etiology of LGLL-related neutropenia is not completely elucidated and several mechanisms, including humoral abnormalities, bone marrow infiltration/substitution and cell-mediated cytotoxicity might cooperate to its pathogenesis. As a consequence of the multifactorial nature of LGLL-related neutropenia, a targeted therapeutic approach for neutropenic patients has not been developed yet; moreover, specific guidelines based on prospective trials are still lacking, thus making the treatment of this disorder a complex and challenging task. Immunosuppressive therapy represents the current, although poorly effective, therapeutic strategy. The recent identification of a STAT3-mediated miR-146b down-regulation in neutropenic T-LGLL patients emphasized the pathogenetic role of STAT3 activation in neutropenia development. Accordingly, JAK/STAT3 axis inhibition and miR-146b restoration might represent tempting strategies and should be prospectively evaluated for the treatment of neutropenic LGLL patients.

Abstract
Large granular lymphocytic leukemia (LGLL) is a rare hematological malignancy that arises from cytotoxic T lymphocytes (T-LGLL) in 85% of cases and natural killer (NK) cells in the rest. A significant knowledge gap exists regarding the pathogenesis, treatment choices, and prognostic factors of LGLL. We report a cohort of 319 consecutive LGLL patients who presented to our cancer center between 2001 and 2020. A total of 295 patients with T-LGLL and 24 with chronic NK-cell lymphoproliferative disorder (CLPD-NK) were identified. The median age was 65 years (range, 17-90 years). Eighty-three patients (26.0%) had autoimmune diseases. A total of 119 patients (37.3%) had coexisting malignancies, 66 (20.7%) had solid tumors, and 59 (18.5%) had hematological malignancies. Most coexisting malignancies were diagnosed before the diagnosis of LGLL. Treatment was needed for 57% of patients. Methotrexate (MTX), cyclophosphamide (Cy), and cyclosporine A (CSA) were most used and had similar response rates between 61.5%-74.4%. Cy produced more complete responses (32.3%) compared to MTX and CSA (15.7% and 23.1%, respectively). Thrombocytopenia, splenomegaly, and female gender (after controlling for autoimmune diseases) were associated with decreased response rates to MTX, CSA, or Cy. Autoimmune diseases were associated with increased response rates. Thrombocytopenia was an independent risk factor for worse survival.

Abstract
Cyclophosphamide (CTX) was used to establish the immunosuppressive mice model. The immune organ viscera index, phagocytes vitality, the levels of cytokines in serum, the oxidative stress resistance, proteomics and intestinal flora in mice were investigated to evaluate the effect of immune regulation of Nigella sativa seed polysaccharide (NSSP). The results showed that the high-dose NSSP group could significantly increase the thymus and spleen index. The levels of ACP, LDH, T-AOC, SOD, IL-2, IL-4 and IL-6 were significantly increased and the levels of TNF-α and MDA were reduced. All evidences indicated that NSSP could improve the immune effects of the immunosuppressed mice. Proteomics investigation showed that NSSP could improve the immune by regulating the differential proteins of PI3K and PTEN, and regulating the metabolism-related pathways such as autoimmune diseases and PI3K-Akt signaling pathway. of Gut microbes analysis showed that NSSP could exert immunomodulatory effects by improving the structure of the intestinal flora, increasing the diversity of the flora, and regulating metabolic pathways such as lipid metabolism, polysaccharide synthesis and signal transduction by the prediction of flora metabolic functions. In addition, NSSP could regulate intestinal environment by regulating the content of short chain fatty acids.

Abstract
Cyclophosphamide is anticancer drug with a well-Known nephrotoxicity. This work was applied to study the lucrative antioxidant influence of metformin as co-therapy on the nephrotoxicity induced by cyclophosphamide in the treatment of different cancer diseases. Four groups of male Sprague Dawley rats were used; Control group (C) received single I.P. injection of 0.2 ml saline, Metformin (MET) group received daily gavage of 200 mg/kg metformin for two weeks, Cyclophosphamide (CP) group received single I.P. injection of 200 mg/kg CP, Protector group (CP.MET) received daily gavage of 200 mg/kg metformin for two weeks and single I.P. injection of 200 mg/kg CP at day 7. By day 14 rats were euthanized. Samples were collected from kidney tissues and blood for kidney function evaluation, histopathological and assessment of oxidative stress markers. The results disclosed that CP yields many functional and structural damage to the kidney, worsened oxidative stress markers and kidney function indicators. The protector group displayed better kidney tissue morphology, acceptable kidney function indicators as well as satisfactory oxidative stress markers. In assumption, metformin could be combined with CP owing to its lucrative effect counter to CP persuaded nephrotoxicity.

Abstract
T-cell large granular lymphocytic leukaemia (T-LGLL) is an incurable leukaemia characterised by clonal proliferation of abnormal cytotoxic T cells that can result in severe neutropenia, transfusion-dependent anaemia and pancytopenia requiring treatment. The most commonly used agents, methotrexate (MTX), cyclophosphamide (Cy) and cyclosporine primarily produce partial remissions (PRs), with few complete responses (CRs). We evaluated the clinical course and treatment response of 60 consecutive patients with T-LGLL to evaluate clinical outcomes and future potential treatment directions. Impaired overall survival was noted among male patients, patients with elevated lactate dehydrogenase, and those without rheumatoid arthritis. Cy was the most efficacious second-line agent, with a 70% overall response rate (ORR; three CR, four PR). All patients who failed frontline MTX responded to second-line Cy. In the relapsed or Cy-refractory setting, alemtuzumab (n = 4) and pentostatin (n = 3) had an ORR of 50% and 66%, respectively, while duvelisib induced a long-term response in one patient. In this large, retrospective analysis, our results suggest Cy is a highly effective therapy for second-line treatment in T-LGLL and should be considered a strong candidate for up-front therapy in select high-risk patients. Prospective studies evaluating pentostatin, alemtuzumab and novel agents, such as duvelisib, are needed for patients with relapsed/refractory T-LGLL.

Abstract
Introduction Cyclophosphamide (CP) causes redox imbalance and its use is associated with marked cardiotoxicity that limits its clinical applications. The present study investigated the protective effects of acetovanillone (AV) and edaravone (ED) against CP-induced oxidative stress and cardiac damage, emphasizing the role of PI3K/Akt/mTOR and Nrf2 signaling. Materials and Methods Rats received either AV (100 mg/kg) or ED (20 mg/kg) orally for 10 days and CP (200 mg/kg) on day 7. At day 11, the rats were sacrificed, and samples were collected for analysis. Results AV and ED ameliorated serum troponin I, CK-MB, LDH, AST and ALP, and prevented cardiac histological alterations in CP-intoxicated rats. Both treatments decreased cardiac lipid peroxidation and enhanced GSH, SOD and cytoglobin in CP-induced rats. AV and ED downregulated Keap1, whereas increased the expression of PI3K, Akt, mTOR and Nrf2 in the heart of rats received CP. Additionally, the binding modes of AV and ED to Keap1 were pinpointed in silico using molecular docking simulations. Conclusion AV and ED prevent CP cardiotoxicity by attenuating oxidative stress and tissue injury, and modulating cytoglobin, and PI3K/Akt/mTOR and Keap1/Nrf2 signaling. Therefore, AV and ED may represent promising agents that can prevent cardiac injury in patients receiving CP.

Nephroprotective effect of exogenous hydrogen sulfide donor against cyclophosphamide-induced toxicity is mediated by Nrf2/HO-1/NF-κB signaling pathway. Life Sci 2020; 264:118630. [PMID: 33169683 DOI: 10.1016/j.lfs.2020.118630] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2020] [Revised: 10/06/2020] [Accepted: 10/17/2020] [Indexed: 02/08/2023]
Abstract
AIM Cyclophosphamide (CP) is an effective anticancer and immunosuppressive agent. However, it induces nephrotoxicity that limits its use. This study explored the effect of H2S, an important biological signaling molecule with a cytoprotective activity, on CP-induced nephrotoxicity. METHODS Male Wistar rats were treated with saline or NaHS (100 μM/kg/day, H2S donor) or dl-propargylglycine (PAG) (30 mg/kg/day, H2S blocker) for 10 days before a single i.p injection of CP (200 mg/kg). Then, rats were sacrificed, and renal functions were assessed in serum. Histopathological changes, as well as oxidant defenses, inflammatory and apoptotic markers in the renal tissue, were evaluated. KEY FINDINGS Pretreatment with NaHS significantly reduced the urea and creatinine levels that were elevated in CP-intoxicated rats. NaHS increased the expression of the cytoprotective nuclear factor erythroid 2-related factor 2 (Nrf2) and its subsequent antioxidant proteins; heme oxygenase-1 (HO-1), NAD(P) H quinone oxidoreductase 1 (NQO1), reduced glutathione (GSH) and superoxide dismutase (SOD). Moreover, NaHS prohibited the histopathological damage induced by CP. The inhibition of caspase-3 and nuclear factor kappa B (NF-κB) supported the protective role of H2S against CP-induced kidney damage. On the other hand, blocking endogenous H2S did not provide a more significant deterioration in CP-induced nephrotoxicity in terms of oxidative stress or inflammatory status. SIGNIFICANCE Exogenous H2S donors exhibited a protective effect against CP-induced nephrotoxicity, which may be mediated via the Nrf2/HO-1/NF-κB signaling pathway. However, endogenous H2S may be insufficient to protect the cell against the induced oxidative damage. This approach provides a novel target to prevent nephrotoxicity of CP.

Abstract
Cyclophosphamide (CP) is widely used as a chemotherapy against various types of cancers. However, CP is accompanied with multiple organ toxicity due to production of reactive oxygen species (ROS), induction of inflammation and consequently apoptosis. Alogliptin (Alo) is a dipeptidyl peptidase 4 (DPP-IV) inhibitor, which is booming as an antidiabetic agent. Interestingly, gliptins are currently studied for their counter-regulatory effects against oxidative stress and inflammation via multiple pathways, among which is the mitogen-activated protein kinase (MAPK)/c-Jun N-terminal kinase (JNK) pathway. This cascade can reduce inflammation via mitigating the activity of mothers against decapentaplegic homolog 3 (SMAD3) and c-Jun. However, Alo effect against CP-induced kidney injury has not been previously elucidated. This tempted us to investigate the possible beneficial effect of Alo against CP-induced kidney injury via modulating the MAP3K/JNK/SMAD3 signaling cascade. Thirty-two male Wistar rats were randomly allocated into four groups. CP-treated group received a single dose of CP (200 mg/kg; i.p.). Alo-treated group received Alo (20 mg/kg/day; p.o.) for 7 days with single CP injection on day 2. Marked decrease in renal injury was observed upon Alo treatment, as evidenced through declined serum kidney function markers, oxidative stress and apoptosis markers, MAP3K expression, phospho (p)-SMAD3, p-JNK, and p-c-Jun levels. These cellular effects were reflected in reduced transforming growth factor beta (TGF-β) and tumor necrosis factor alpha (TNF-α) fibrotic and inflammatory mediators, coinciding with improved histopathological portrait. In conclusion, the current study provides novel application of Alo as a therapeutic modality against CP-induced nephrotoxicity.

Abstract
Cyclophosphamide (CP) is one of the most potent alkylating agents and is widely used in the treatment of numerous neoplastic conditions, autoimmune diseases and following organ transplantation. Due to its ability to induce oxidative stress and subsequent apoptosis, CP is affiliated with many adverse effects with special emphasis on the highly prevalent hepatotoxicity. Dipeptidyl peptidase 4 (DDP-IV) inhibitors are being rediscovered for new biological effects due to their ability to target multiple pathways, among which is the phosphoinositide 3-kinase (PI3K) and protein kinase B (Akt) axis. This could offer protection to multiple organs against reactive oxygen species (ROS) through modulating sirtuin 1 (SIRT1) expression and, in turn, inactivation of forkhead box transcription factor of the O class 1 (FoxO1), thus inhibiting apoptosis. Accordingly, the current study aimed to investigate the potential therapeutic benefit of alogliptin (Alo), a DPP-IV inhibitor, against CP-induced hepatotoxicity through enhancing PI3K/Akt/SIRT1 pathway. Forty male Wistar rats were randomly divided into four groups. The CP-treated group received a single dose of CP (200 mg/kg; i.p.). The Alo-treated group received Alo (20 mg/kg; p.o.) for 7 days with single CP injection on Day 2. Alo successfully reduced hepatic injury as witnessed through decreased liver function enzymes, increased phospho (p)-PI3K, p-Akt, superoxide dismutase (SOD) levels, SIRT1 expression, p-FoxO1 and anti-apoptotic B-cell lymphoma 2 (Bcl-2). This resulted in decreased apoptosis, as witnessed through decreased caspase-3 levels and improved histopathological picture. In conclusion, the current study succeeded to elaborate, for the first time, the promising impact of Alo in ameliorating chemotherapy-induced liver injury.

Abstract
T-cell large granular lymphocyte (LGL) leukemia is a rare indolent neoplasm primarily treated with immunosuppression. Few therapies and no consensus exist for the optimal treatment of T-cell LGL leukemia refractory to immunosuppressive therapy. Here, we report a case of relapsed/refractory T-cell LGL treated with belinostat. A 57-year-old male presented with lymphocytosis and anemia and was found to have T-cell LGL, requiring frequent packed red blood cell transfusions. He was initially treated with methotrexate with no response after 7 months. He was then switched to cyclosporine and cyclophosphamide and experienced transfusion independence for 42 months before disease relapse. He was then started on belinostat with noted subsequent transfusion independence for greater than 15 months to date and decreased disease involvement on bone marrow biopsy. To our knowledge, this is the first reported case of belinostat use in relapsed/refractory T-cell LGL leukemia which resulted in a durable clinical and biologic response.

Abstract
PURPOSE OF REVIEW The past decade in LGL leukemia research has seen increased pairing of clinical data with molecular markers, shedding new insights on LGL leukemia pathogenesis and heterogeneity. This review summarizes the current standard of care of LGL leukemia, updates from clinical trials, and our congruent improved understanding of LGL pathogenesis. RECENT FINDINGS Various clinical reports have identified associations between stem, bone marrow, and solid organ transplants and incidence of LGL leukemia. There is also a potential for underdiagnosis of LGL leukemia within the rheumatoid arthritis patient population, emphasizing our need for continued study. Preliminary results from the BNZ-1 clinical trial, which targets IL-15 along with IL-2 and IL-9 signaling pathways, show some evidence of clinical response. With advances in our understanding of LGL pathogenesis from both the bench and the clinic, exciting avenues for investigations lie ahead for LGL leukemia.

Abstract
Curcumin (CUR) has been used since ancient times to treat several ailments as it possesses many pharmacological activities. This study intended to explore the mechanism underlying the protective effects of CUR in remodeling oxidative stress and apoptotic signals in cyclophosphamide (CP)-induced pulmonary injury in albino rats. CUR was administered at a dose of 300 mg/kg/day for 7 days and on the seventh day a single dose of CP (200 mg/kg) was given. Histopathological and ultrastructural examinations of CP-intoxicated rats showed complete alveolar obstruction, thickened inter-alveolar septa, enlarged blood vessels, severe inflammatory edema with pyknotic nuclei, and disappearance of cytoplasmic organelles. Significant increases in caspase-3, malondialdehyde (MDA), and protein carbonyl (PCO) and significant decreases in superoxide dismutase (SOD) and glutathione peroxidase (GPx) were observed. In contrast, rats that received CUR showed clear and empty lumina with single row of pneumocytes, disappearance of edema, and no interstitial electron dense bodies in rats’ lung tissues. Additionally, CUR significantly reduced caspase-3, MDA, and PCO and increased SOD and GPx. In conclusion, these findings revealed the protective effects of CUR against CP-induced pulmonary injury in rats through suppressing oxidative damage and apoptosis.

Abstract
BACKGROUND AND AIMS Cyclophosphamide (CPh) is a frequently used drug, in human and animals for its immunosuppressive and anticancer potential. However, it is metabolized by the liver yielding damaging toxicants (to the liver itself and other non-target vital organs) via oxidative stress, apoptosis induction and finally necrosis. Since there is no escaping of using such harmful medications, we focused on alleviating its side-effects. Panax ginseng Meyer is a potent candidate, and we still lack adequate information on its hepatoprotective role against cyclophosphamide-induced liver-damage. METHODS Here, we used P. ginseng (Korean Red Ginseng) compared to vitamin-E (natural antioxidant) in combating CPh-induced liver damage. Forty-eight albino rats were divided into 6 groups, Control, Ginseng, Vitamin E, Cyclophosphamide (CPh), CPh + Ginseng or CPh + Vitamin-E. Blood samples were taken for biochemical analyses and liver samples were collected for histopathology, oxidative stress evaluation, and gene expression analyses. RESULTS In CPh group, typical CPh-liver damage was evident (higher levels of AST, ALT, ALP; lower albumin and total proteins levels; lower liver tissue concentrations of SOD, GPX and CAT and higher MDA; injured liver histopathological picture; and finally increased TNF-α, IL-1β and Caspase3 and decreased BCL-2 genes expression). All these were abolished with either P. ginseng or vitamin-E administration. However, P. ginseng was overall superior to vitamin-E, especially in restoring blood biochemical findings and damaged histopathological picture. CONCLUSIONS Therefore, P. ginseng is a potent hepatoprotector (vitamin-E to a lesser extent) and should be considered where liver damage is expected secondary to damaging medications; as cyclophosphamide.

Abstract
Cyclophosphamide (CP) is a widely used chemotherapeutic agent; however, its clinical application is limited because of its multi-organ toxicity. Galangin (Gal) is a bioactive flavonoid with promising biological activities. This study investigated the hepatoprotective effect of Gal in CP-induced rats. Rats received Gal (15, 30 and 60 mg/kg/day) for 15 days followed by a single dose of CP at day 16. Cyclophosphamide triggered liver injury characterized by elevated serum transaminases, alkaline phosphatase (ALP) and lactate dehydrogenase (LDH), and histopathological manifestations. Increased hepatic reactive oxygen species, malondialdehyde, nitric oxide, and oxidative DNA damage along with declined glutathione and antioxidant enzymes were demonstrated in CP-administered rats. CP provoked hepatic nuclear factor-kappaB (NF-κB) phosphorylation and increased mRNA abundance of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), and tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β) both expression and serum levels. Gal prevented CP-induced liver injury, boosted antioxidants and suppressed oxidative stress, DNA damage, NF-κB phosphorylation and pro-inflammatory mediators. Gal diminished Bax and caspase-3, and increased B-cell lymphoma-2 (Bcl-2) in liver of CP-administered rats. In addition, Gal increased peroxisome proliferator-activated receptor gamma (PPARγ) expression and activated hepatic nuclear factor erythroid 2-related factor 2 (Nrf2) signaling showed by the increase in Nrf2, NAD(P)H: quinone acceptor oxidoreductase-1 (NQO-1) and heme oxygenase 1 (HO-1) in CP-administered rats. These findings suggest that Gal prevents CP hepatotoxicity through activation of Nrf2/HO-1 signaling and attenuation of oxidative damage, inflammation and cell death. Therefore, Gal might represent a promising adjuvant therapy to prevent hepatotoxicity in patients on CP treatment.

Abstract
In the study, the protective effect of plasma protein from Tachypleus tridentatus (PPTT) on acute kidney injury (AKI) and the related molecular mechanisms were first investigated by Western blotting analyses, TdT-mediated dUTP Nick-End Labeling (TUNEL) assay, and immunohistochemistry. It was found that PPTT had an obviously inhibitory effect on Reactive oxygen species (ROS) in cyclophosphamide (CTX)-exposed mice. Furthermore, results demonstrated that the renal cell death mode is due to inducing apoptosis and autophagy inhibited by dose-dependent PPTT in mice treated with CTX by decreasing the protein expression of bax, beclin-1, and LC3 and increasing the expression of bcl-2. Moreover, the p38 MAPK and PI3K/Akt signaling pathways were observed to take part in the PPTT-induced renal cell growth effect by enhancing the upregulation of the expression of Akt and p-Akt as well as the downregulation of the expression of p38 and p-p38, which indicated a PPTT ameliorating effect on AKI CTX-induced in mice through p38 MAPK and PI3K/Akt signaling pathways. Briefly, this article preliminarily studies the mechanism of the PPTT ameliorating effect on AKI CTX-induced in mice, which helps to provide a reference for PPTT clinical application in AKI therapy.

Abstract
Large granular lymphocyte (LGL) leukemia has been recognized in the World Health Organization classifications among mature T cell and natural killer cell neoplasms and is divided into three categories. Chronic T cell leukemia and natural killer cell lymphocytosis can be considered as a similar spectrum of an indolent disease characterized by cytopenias and autoimmune conditions. The last category, aggressive natural killer cell LGL leukemia is very rare, related to Epstein-Barr virus, and seen mainly in young Asian people. Clonal LGL expansion arises from chronic antigenic stimulation sustained by interleukin-15 and platelet-derived growth factor cytokine signal. Those leukemic cells are resistant to apoptosis, mainly because of constitutive activation of survival pathways including Jak/Stat, MapK, Pi3k-Akt, RasRaf-1, MEK1/ERK, sphingolipid, and NFκB. Stat3 constitutive activation is the hallmark of this lymphoproliferative disorder. Socs3 is downregulated, but no mutation could be found to explain this status. However, several somatic mutations, including Stat3, Stat5b, and tumor necrosis factor alpha-induced protein 3, have been demonstrated recently in LGL leukemia; they are identified in half of patients and cannot explain by themselves LGL leukemogenesis. Recurrent infections as a result of chronic neutropenia, anemia, and autoimmune disorders are the main complications related to LGL leukemia. Despite an indolent presentation, 10% of patients die, mainly because of infectious complications. Current treatments are based on immunosuppressive therapies. A better mechanistic understanding of LGL leukemia will allow future consideration of a personalized therapeutic approach perhaps based on Jak/Stat inhibitors, which may offer better results than current immunosuppressive therapy.

Abstract
OBJECTIVE Up to one-third of patients with T cell large granular lymphocyte (T-LGL) leukemia display symptoms of rheumatoid arthritis (RA). In Crohn's disease and psoriasis, treatment with tumor necrosis factor (TNF) inhibitors is associated with hepatosplenic γδ T cell lymphoma and with clonal expansion of γδ T cells, respectively. This study was undertaken to determine the prevalence of clonal T-LGL cells in patients with RA and define risk factors for this rare hematologic malignancy. METHODS A total of 529 RA patients were recruited between November 2013 and August 2015. Eight-color flow cytometry (fluorescence-activated cell sorting [FACS]) was performed to screen for aberrant T cell populations of LGLs. Molecular analysis of the T cell receptor was used to confirm the diagnosis in patients with suggestive FACS findings. Electronic patient files were used to determine risk factors. Patients with clonal populations were monitored prospectively for up to 4 years. RESULTS The median patient age was 61 years, and 74% were female. The median duration of RA was 12 years. The median Disease Activity Score in 28 joints was 2.8, and 69.9% of patients had ever been treated with biologic disease-modifying antirheumatic drugs. We identified clonal T-LGL expansions in 19 patients, equaling a prevalence of 3.6%. The T-LGL cell clone was constant over time in most patients and was significantly associated with the duration of the exposure to TNF-blocking agents (P = 0.01). No other risk factors could be detected. CONCLUSION RA patients with long-term exposure to TNF-blocking agents were at a greater risk of developing clonal expansions of LGLs. This finding may prompt clinicians to refrain from using these substances in RA patients with known T cell aberrations.

Abstract
In humans, large granular lymphocytic leukaemia (LGLL) is a low-grade, indolent lymphoproliferative disorder of large granular lymphocytes (LGL) associated with autoimmune disorders; including rheumatoid arthritis and single or multiple cytopenias; particularly neutropenia. Therapy largely centres around immunosuppression which aims to resolve the immune-mediated secondary pathology, often without eradicating the neoplastic clone. The most effective agents appear to be cyclophosphamide, cyclosporine and methotrexate. This case report describes the presentation, diagnostics, therapeutic approach and outcome of a 6 year-old Golden Retriever presenting with severe neutropenia. Chlorambucil, prednisolone and cyclosporine failed to improve the neutropenia but subsequent cyclophosphamide resulted in a sustained albeit temporary improvement in neutrophil count and the ability to withdraw prophylactic antibacterials. This case closely mirrors the diagnostics and therapeutic response in human LGLL.

Abstract
AIM To assess the effect of human umbilical cord mesenchymal stem cells (UC-MSCs) on cyclophosphamide (CTX)-induced liver injury.
METHODS UC-MSCs were isolated from the human umbilical cord. Male SD rats were randomly divided into three groups: control group, CTX group, and CTX + UC-MSC group. The CTX group and CTX + UC-MSC group were intraperitoneally injected with CTX. After that, the control group and CTX group were injected with water via the tail vein, and the CTX + UC-MSC group was injected with MSCs via the tail vein. Six rats of each group were selected randomly and sacrificed at different time points. Blood samples were taken to measure serum alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), and total bilirubin (TBIL). Liver tissues were collected for biochemical assays of malondialdehyde (MDA), lipid peroxide (LPO), NO, glutathione (GSH), glutathione peroxidase (GSH-PX), and total superoxide dismutase (T-SOD). qPCR was used to test the expression of Bcl-2, Bax, and vascular endothelial growth factor (VEGF) A. Histological examination (HE straining) and immunohistochemical staining for α-smooth muscle actin (α-SMA) and Ki-67 were also performed.
RESULTS Compared with the control group, the levels of ALT, AST, ALP, and TBIL were significantly higher, the SOD, GSH, and GSH-PX contents were significantly lower, MDA, LPO, and NO were significantly higher, cell apoptosis significantly increased, and the expression of VEGFA significantly decreased in the CTX group. Compared with the CTX group, the ALT, AST, ALP, and TBIL were significantly lower, the SOD, GSH, and GSH-PX contents were significantly higher, and MDA, LPO, and NO were significantly lower in the CTX + UC-MSC group (P < 0.05). The expression of Bax was lower and Bcl-2 and VEGFA expression was higher in the CTX + UC-MSC group than in the CTX group (P < 0.05). Pathological analysis showed that liver status was better in the CTX + UC-MSC group than in the CTX group. The α-SMA+ cells in the CTX + UC-MSC group were less than and Ki-67+ cells were more than those in the CTX group (P < 0.05).
CONCLUSION UC-MSCs injected via the tail vein could alleviate CTX-induced hepatotoxicity in rats.

Abstract
AIM: The present study investigated the protective effect of the phytoestrogen, genistein (GEN), against (CP)-induced acute hepatotoxicity in rats. MATERIAL AND METHODS: Male adult rats were randomly assigned into five groups. Normal control group received the vehicles; CP group received a single dose of CP (200 mg/kg, i.p). The other three groups received subcutaneous GEN at doses of 0.5, 1 and 2 mg/kg/day, respectively, for 15 consecutive days prior CP injection. Sera and liver tissues were collected forty-eight hours after CP injection for assessment of liver function enzymes (ALT and AST) in rat sera, the hepatic oxidative/nitrosative biomarkers (GSH, MDA and NOx), hepatic interleukin-1β, and myeloperoxidase activity. Immunohistochemistry of cyclooxygenase-2 and histopathological examination of liver tissues were also conducted. RESULTS: The CP-induced acute liver damage was evidenced by elevated serum ALT and AST accompanied by increased hepatic oxidative stress and inflammatory biomarkers. Immunohistochemical outcomes revealed hepatic cyclooxygenase-2 expression in CP group with distortion of liver architecture. GEN-pretreatment significantly ameliorated the deterioration of liver function and exerted significant anti-oxidant and anti-inflammatory activity with a marked decline in hepatic cyclooxygenase-2 expression in a dose dependent-manner. CONCLUSION: The present study demonstrated that the antioxidant and anti-inflammatory activities of GEN might contribute to its protective effects against CP-induced liver damage.

Abstract
Large granular lymphocytic leukemia (LGLL) represents a clonal/oligoclonal lymphoproliferation of cytotoxic T and natural killer cells often associated with STAT3 mutations. When symptomatic, due to mostly anemia and neutropenia, therapy choices are often empirically-based, because only few clinical trials and systematic studies have been performed. Incorporating new molecular and flow cytometry parameters, we identified 204 patients fulfilling uniform criteria for LGLL diagnoses and analyzed clinical course with median follow-up of 36 months, including responses to treatments. While selection of initial treatment was dictated by clinical features, the initial responses, as well as overall responses to methotrexate (MTX), cyclosporine (CsA), and cyclophosphamide (CTX), were similar at 40-50% across drugs. Sequential use of these drugs resulted in responses in most cases: only 10-20% required salvage therapies such as ATG, Campath, tofacitinib, splenectomy or abatacept. MTX yielded the most durable responses. STAT3-mutated patients required therapy more frequently and had better overall survival.
