It presents a diagnostic challenge to the neonatologists due to a lack of objective evaluation. It may mimic noninfective conditions, such as inborn error of metabolism, birth asphyxia, and even respiratory distress syndrome in preterms. Nonetheless, over-diagnosis and initiating unwanted empirical antibiotics may pose the threat of drug resistance, increasing the hospital stay and cost of treatment. Traditionally, investigations such as white blood cell count, absolute neutrophil count, immature to total neutrophil ratio, C-reactive protein levels, and blood cultures have been used to diagnose sepsis. However, these have low sensitivity and specificity because they may be elevated in conditions other than sepsis. The in-depth understanding of the neonatal immune system’s response to early infection has led to the discovery of advanced diagnostic tools, including biomarkers.\u0000\u0000This literature review briefs on the various haematological parameters and biomarkers in neonatal sepsis, exploring newer biomarkers and comparing them with their older counterparts. This will help early diagnosis, treatment, and improved prognosis in neonatal sepsis. As there is a spectrum of markers for diagnosing neonatal sepsis, it is preferable to compile these markers and correlate clinically.\u0000\u0000A thorough search of this literature was done on the electronic databases PubMed, Elsevier’s Web of Science, and the Cochrane Library. The authors found around 90 relevant articles: 84 were from PubMed, 4 from Elsevier, and 2 from the latest Cochrane database.

An update from the PRIMA study showed that 10-year progression-free survival (PFS) was improved following the use of R maintenance compared with observation following induction. Prof Salles also provided an overview of the RELEVANCE study data, which showed that R plus lenalidomide was not superior to standard R-chemo for the treatment of first-line FL.\u0000\u0000Prof Seymour presented data showing that two-thirds of premature FL deaths occur in patients experiencing disease progression within 2 years of treatment, highlighting the need to identify patients at early risk of progression. Prof Seymour explored various prognostic and predictive tools that could be used to identify patients at high risk of death, but he noted that until these prognostic tools are available in the clinic, the high-risk population remains unidentifiable. Furthermore, the accuracy of these prognostic indices needs to be improved. Data analysis from the GALLIUM study showed that G-chemo decreased the risk of a disease progression event in the first 2 years by 46% compared to R-chemo.\u0000\u0000Prof Trotman explored the use of PET imaging and detection of minimal residual disease (MRD) to assess treatment outcomes. Prof Trotman showed that PET status at the end of induction is highly prognostic of the outcome. An exploratory analysis of the GALLIUM data showed that the application of the Lugano 2014 response criteria showed a rapid, deep separation of the PFS curves of patients achieving a complete metabolic response (CMR) versus those who did not. There was almost a 5-fold increase in risk of progression and in risk of death in patients failing to achieve CMR. An exploratory analysis of the MRD status of GALLIUM patients showed that a greater proportion of patients in the G-chemo arm achieved MRD-negative status at the end of induction (EOI). Interestingly, patients achieved similar MRD outcomes with G-chemo, regardless of chemotherapy backbone. Both PET and MRD status after induction were independently predictive of PFS.\u0000\u0000Dr Pettengell and Mr Bouguet discussed FL from both the clinician’s and the patient’s perspective, with a focus on health-related quality of life (HRQoL). They demonstrated how a marked decrease in HRQoL at progression highlights the importance of extending remission for FL patients. Dr Pettengell presented data from GALLIUM showing comparable quality of life for patients treated with either G-chemo or R-chemo. They also presented patient surveys showing that FL has a substantial physical and psychological impact on patients that both lasts beyond treatment and persists even during long-term remission.","PeriodicalId":326555,"journal":{"name":"EMJ Hematology","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130235887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, major challenges remain: a) RTX is often used with toxic chemotherapy that not only causes serious side effects but may also compromise RTX activity and host antitumour immunity, predisposing patients to relapse; b) indolent low-grade BNHL remain largely incurable; c) a significant percentage of aggressive BNHL do not respond to RTX-based therapy; and d) a significant number of responders may eventually relapse in long-term follow-up. The data suggest that the limit in the efficacy may result from the inability of RTX to directly kill lymphoma cells. RTX primarily relies on indirect mechanisms to attack lymphoma cells, which include complement-dependent cytotoxicity, Ab-dependent cellular cytotoxicity, induction of apoptosis, and immune activation. These mechanisms could be readily compromised by various situations, such as chemotherapy. The new generation of anti-CD20 Ab have not been found to be directly cytotoxic. Cytotoxic radioactive isotope-conjugated anti-CD20 Ab appeared to be highly effective, but serious radiotoxicity prohibited their clinical application. Increasing Ab valency augments activity; a recent study has demonstrated drastic improvement in activity by non-covalently associating RTX with nanomaterial graphene oxide (GO). The multivalent Ab product RTX/GO is highly cytotoxic, capable of directly killing BNHL cells in vitro and rapidly eliminating established xenograft lymphoma in vivo in the absence of toxic chemo-agents. While further studies are needed to determine the mechanism of activity and clinical efficacy, the current data suggest a significant possibility that RTX/GO might constitute nontoxic but effective therapy for BNHL.","PeriodicalId":326555,"journal":{"name":"EMJ Hematology","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124993843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Established therapeutic options for these patients remain limited. Fortunately, recent advancements in the knowledge of MDS pathogenesis have allowed for the development of many targeted therapies, including epigenetic regulators, signal transduction regulators, immune checkpoint inhibitors, cell apoptosis regulators, and novel cytotoxic agents. These novel therapeutics have shown varying degrees of promise in clinical trials. Epigenetic regulators, such as second-generation HMA and isocitrate dehydrogenase inhibitors, have shown modest efficacy in early studies, while histone deacetylase inhibitors have, thus far, failed to show significant clinical benefit. Signal transduction modulators, such as transforming growth factor (TGF)-β inhibitors and toll-like receptor inhibitors, appear to alleviate anaemia symptoms, but further studies are needed to determine their effect on survival. Rigosertib, a multikinase inhibitor, improved survival in a small subset of patients with very high-risk MDS. Immune checkpoint inhibitors have shown mixed results. Agents that have recently been approved for use in specific types of high-risk acute myeloid leukaemia, including FMS-like tyrosine receptor kinase 3 inhibitors and CPX-351, are also being studied for use in MDS, with early studies suggesting efficacy. Several other agents are also under investigation with results pending. These novel agents represent potential therapeutic options for patients who have failed HMA and for whom no currently established therapies are available.","PeriodicalId":326555,"journal":{"name":"EMJ Hematology","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114901187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the first presentation, Dr Soverini and Prof Lion discussed the importance of the timing and depth of response with respect to clinical outcomes in Philadelphia chromosome positive (Ph+) leukaemias. They showed how sensitive and reproducible measurements of molecular response (MR) and the proper interpretation of laboratory data are critical to correctly inform therapeutic decisions in patients with chronic myeloid leukaemia (CML) and Ph+ acute lymphoblastic leukaemias (ALL). Detection of BCR-ABL mutations can establish the need for treatment change and, in some cases, indicate which tyrosine-kinase inhibitor (TKI) is most likely to be effective. The speakers addressed the need for more sensitive and accurate methods to monitor minimal residual disease (MRD) and detect mutations that drive resistance to TKI therapy. They explored two distinct patterns of mutation observed in patients with >1 mutation (polyclonal and compound mutations) and how in addition to selecting the most appropriate TKI it is also important to consider the most appropriate dose.\u0000\u0000In the second presentation, Dr Bassan and Prof Dr Junghanß discussed the evolving treatment landscape for Ph+ ALL, including the role of TKI, chemotherapy, and allogenic stem cell transplantation (SCT). The advent of TKI has improved the prognosis for Ph+ ALL, allowing many more patients to achieve complete remission and be considered for allogeneic SCT. However, treatment-related mortality remains a significant issue after allogenic SCT affecting 20–33% of patients.\u0000\u0000Studies show that early death rates are lower for patients receiving ‘light’ chemotherapy and TKI with steroids in place of chemotherapy. Furthermore, for patients achieving complete MR, in some studies there is no difference in outcome between those who undergo allogenic SCT and those who do not, provided that the latter subgroup was selected according to absence of residual disease by PCR analysis. Such data suggest that, in Ph+ ALL, novel therapeutic approaches may in some patients obviate the need for intensive chemotherapy and allogeneic SCT. Studies are now ongoing to explore whether Ph+ ALL patients can abstain from allogenic SCT through selection of the strongest TKI upfront and whether chemotherapy-free regimens might be an option.","PeriodicalId":326555,"journal":{"name":"EMJ Hematology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128352775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At least half of the cases of anaemia in pregnant women are assumed to be due to iron deficiency, with folate or vitamin B12 deficiency, chronic inflammatory disorders, parasitic infections like malaria, and certain inherited disorders accounting for the remaining cases. A considerable variation has been observed in the incidence and aetiology of iron deficiency anaemia among developed and developing nations, warranting differences in the screening protocols and management strategies used by clinicians in these countries.

Scarisbrick","doi":"10.33590/emjhematol/10313097","DOIUrl":"https://doi.org/10.33590/emjhematol/10313097","url":null,"abstract":"Mycosis fungoides (MF) is the most common variant of cutaneous T cell lymphoma and frequently presents as early-stage disease with skin patches and plaques with an indolent course, but patients experience significant morbidity from itch and disfigurement. Around 30% of patients with MF present in the advance stages with skin tumours, erythroderma, and extensive nodal or visceral involvement. Sézary syndrome (SS) is the leukaemic cutaneous T cell lymphoma variant. The staging of MF or SS was revised in 2007 to include skin, nodal, visceral, and blood (tumour- node-metastasis-blood classification) to determine nine stages (IA–IVB). While most patients with early disease (Stages IA–IIA) have a good prognosis, 25% progress to advanced disease, with a poor life expectancy of around 3 years; however, some patients do survive for ≥10 years. Accurate staging is crucial since management strategies are stage-based, with skin-directed therapy recommended in early-stage disease and with no curative therapeutic options to improve symptoms and reduce skin tumour burden. In contrast, advanced-stage patients mostly require systemic therapy. Most treatments have only partial response rates, around 40%, and allogeneic bone marrow transplant may provide a more long-lasting therapeutic option for advanced patients.\u0000\u0000Relevant prognostic factors within the tumour-node-metastasis-blood classification are discussed in this review and their relevance to overall IA–IVB staging and outcomes are debated. Several important prognostic features have been identified that may be used alongside staging to give further prognostic information. These prognostic features include age >60 years at diagnosis, large cell transformation of the skin, and raised serum lactate dehydrogenase levels, which could be developed into a prognostic index to identify patients at risk of progression and requiring more aggressive therapy. The PROCLIPI study, a prospective cutaneous lymphoma international study, has been ongoing since 2015 to collect such data, with the aim of developing a prognostic index for MF and SS.","PeriodicalId":326555,"journal":{"name":"EMJ Hematology","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132290120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
