RESUMO

Background: X-Linked Moesin-Associated Immune Deficiency (X-MAID) is a rare severe combined immunodeficiency (SCID) subtype that can present at any age due to its variability. Depending on severity, patients demonstrate failure to thrive, recurrent bacterial and viral infections, and increased susceptibility to varicella zoster. It has been characterized by marked lymphopenia with hypogammaglobulinemia and impaired T-cell migration and proliferation. Case Presentation: This is a report of a Cuban 7-year-old male with poor weight gain and facial dysmorphia. He had a history of recurrent bacterial gastrointestinal infections and pneumonia beginning at 4 months of age. He additionally had 4-6 upper respiratory tract and ear infections annually. While still living in Cuba, he was admitted for a profound EBV infection in the setting of significant leukopenia. A bone marrow biopsy confirmed no malignancy. After he moved to the United States, his laboratory work-up revealed marked leukopenia with low absolute neutrophil and lymphocyte count with low T and B cells, very low immunoglobulin levels IgG, IgA, and IgM, and poor vaccination responses to streptococcus pneumonia, varicella zoster, and SARS-CoV-2. Genetic testing revealed a missense pathogenic variant c.511C>T (p.Arg171Trp) in the moesin (MSN) gene associated with X-MAID. He was managed with Bactrim and acyclovir prophylaxis, and immunoglobulin replacement therapy, and considered for hematopoietic stem cell transplantation. Discussion(s): Diagnosis of X-MAID should be considered in patients with recurrent infections and profound lymphopenia. As with SCID, early diagnosis and intervention is of utmost importance to prevent morbidity and mortality. This case demonstrates the importance of genetic testing in identifying this disease as it may prompt an immunologist to consider HSCT if conservative management is suboptimal. In the current literature, HSCT appears promising, but the long-term outcomes have yet to be described.Copyright © 2023 Elsevier Inc.

RESUMO

Submission content Introduction: At the end of a particularly hectic night shift on the intensive care unit (ICU) I found myself sitting in the relatives' room with the mother and aunt of a young patient, listening to their stories of her hopes and aspirations as she grew up. She had been diagnosed with lymphoma aged 14 and received a bone marrow transplant from her younger sister. Fighting through treatment cycles interposed with school studies, she eventually achieved remission and a portfolio of A-levels. Acceptance into university marked the start of a new era, away from her cancer label, where she studied forensic science and took up netball. Halfway through her first year she relapsed. Main body: When I met this bright, ambitious 20-year-old, none of this history was conveyed. She had been admitted to ICU overnight and rapidly intubated for type-1 respiratory failure. The notes contained a clinical list of her various diagnoses and treatments, with dates but no sense of the context. Rules regarding visitation meant her family were not allowed onto the unit, with next-of-kin updates carried out by designated non-ICU consultants to reduce pressures on ICU staff. No photos or personal items surrounded her bedside, nothing to signify a life outside of hospital. She remained in a medically-induced coma from admission onwards, while various organ systems faltered and failed in turn. Sitting in that relatives' room I had the uncomfortable realisation that I barely saw this girl as a person. Having looked after her for some weeks, I could list the positive microbiology samples and antibiotic choices, the trends in noradrenaline requirements and ventilatory settings. I had recognised the appropriate point in her clinical decline to call the family in before it was too late, without recognising anything about the person they knew and loved. She died hours later, with her mother singing 'Somewhere Over the Rainbow' at her bedside. Poignant as this was, the concept of this patient as more than her unfortunate diagnosis and level of organ failure had not entered my consciousness. Perhaps a coping mechanism, but dehumanisation none-the-less. Conclusion(s): Striking a balance between emotional investment and detachment is of course vital when working in a clinical environment like the ICU, where trauma is commonplace and worst-case-scenarios have a habit of playing out. At the start of my medical career, I assumed I would need to consciously take a step back, that I would struggle to switch off from the emotional aspects of Medicine. However, forgetting the person behind the patient became all too easy during the peaks of Covid-19, where relatives were barred and communication out-sourced. While this level of detachment may be understandable and necessary to an extent, the potential for this attitude to contribute to the already dehumanising experience of ICU patients should not be ignored. I always thought I was more interested in people and their stories than I was in medical science;this experience reminded me of that, and of the richness you lose out on when those stories are forgotten.

RESUMO

Our charity's mission is dedicated to beating blood cancer by funding research and supporting those affected. Since 1960, we have invested over 500 million in blood cancer research, transforming treatments and saving lives. Since 2015 there has been a Support Services team within the charity. This service was established to provide information that the blood cancer community can trust, in a language they can understand. By connecting and listening to our community they deepen our understanding and help shape our work. Research suggests that blood cancer patients are more likely than any other patients to leave their diagnosis appointment feeling they do not fully understand their condition. Our service can often consolidate the information given by clinicians. Patients also need advice and support on how to adapt to day-to- day life after their diagnosis. There are challenges that are unique to blood cancer, such as living with cancer as a chronic condition, being on 'watch and wait' or fluctuating remissions and relapses. In 2023 the Support Services team have a 7 day presence on our phone line, email and social media platform where people can communicate with one of our trained blood cancer support officers, or one of three Registered Nurses, all who can provide information about blood cancer diagnosis and help with emotional and practical support. We also run an online community forum where people affected by blood cancer can connect, share experiences and provide peer support. The highly experienced haematology nurses provide a clinical aspect to the support of the Blood Cancer Community that enhances the established patient centred support given historically by the charity. The nurses advanced knowledge and experience of haematological cancers, treatments, side effects, holistic care and NHS process can further guide the community. This is in addition to the invaluable information from their treatment teams. In 2023 the Support Services team are now reaching thousands of the blood cancer community. We understand that in the past 3 years the COVID-19 pandemic and the work of our charity around this will have influenced the significant increase in contacts but equally the robust and trusted services provided through this charity has contributed too.

RESUMO

In phase 1 of CC-92480- MM- 001 (NCT03374085), the recommended phase 2 dose (RP2D) of mezigdomide plus dexamethasone (MEZI-d) was selected at 1 mg once daily for 21/28 days. Here we report preliminary results from the MEZI-d dose-expansion cohort in patients with heavily pretreated RRMM. Key eligibility criteria were: RRMM;>=3 prior lines of therapy;disease progression <=60 days of last myeloma therapy;refractoriness to lenalidomide/pomalidomide, a proteasome inhibitor, a glucocorticoid, and an anti-CD38 monoclonal antibody. Oral mezigdomide 1 mg was given on days 1-21 of each 28-day cycle, plus weekly dexamethasone (40 mg;20 mg if >75 years of age). Primary objective was to evaluate efficacy (overall response rate [ORR]);secondary objectives included safety/tolerability and additional efficacy assessments. Pharmacodynamics was an exploratory objective. As of 16/Sep/2022, 101 patients had received MEZI-d at the RP2D. Median age was 67 (range 42-85) years, median time since initial diagnosis was 7.4 (1.1-37.0) years;39.6% of patients had plasmacytomas and 37/101 patients had high-risk cytogenetics (56/101 not evaluable). Median number of prior regimens was 6 (3-15);prior therapies included stem cell transplantation (77.2%) and anti-BCMA therapy (29.7%). All patients were refractory to last myeloma regimen and triple-class refractory. Median follow-up was 7.5 (0.5-21.9) months, with a median of 4 (1-20) cycles;10.0% of patients continued treatment;progressive disease was the main reason for discontinuation (60.4%). ORR was 40.6% for all patients. Whilst data are not mature yet, median PFS was 4.4 (95% CI 3.0-5.5) months and median duration of response was 7.6 (95% CI 5.4-9.5) months. ORR was 30.0% in patients with plasmacytomas (N = 40) and 50.0% in patients with prior anti-BCMA therapy (N = 30). Ninety-one (91.1%) patients experienced a grade 3/4 treatment-emergent adverse event (TEAE). Most frequent hematologic grade 3/4 TEAEs were neutropenia (75.2%), anaemia (35.6%), and thrombocytopenia (27.7%);34.7% of patients had grade 3/4 infections, including grade 3/4 pneumonia (15.8%) and COVID-19 (7.0%). Occurrence of other grade 3/4 non-hematologic TEAEs was generally low. Due to TEAEs, 76.2% and 29.7% of patients had mezigdomide dose interruptions and reductions, respectively;90.1% of patients discontinued mezigdomide. Mezigdomide induced substrate degradation and increases in activated and proliferating T cells in patients, including those directly refractory to pomalidomide-based therapies. MEZI-d had a manageable safety profile with encouraging efficacy in patients with triple-class refractory RRMM, including patients with prior BCMA-targeted therapies. These results strongly support the continued development of mezigdomide in MM, and especially in combination.

RESUMO

Introduction: Croatian National Cancer Registry of Croatian Institute for Public Health reported that in year 2020 lung cancer was the second most common cancer site diagnosed in men with 16% and the third most common in women with 10% incidence among all cancer sites. Unfortunatelly lung cancer has the highest mortality in both men and women. Haematological malignancies had 7% share in all malignancies in both male and female cances cases. In 2020 190 newly diagnosed cases of lymphatic leukemia in men and 128 cases in women were reporeted, meaning 1.5 and 1.2% of all malignancies, respectively. Chronic lymphatic leukemia (CLL) is an advanced age disease and incidence increases with age. Impaired immunity, T and B cell dysfunction in CLL, chromosomal aberations, long-term immunosuppressive therapy and genetic factors can all cause secondary malignancies. Co- occurence of solid tumors and CLL is very rare. Although patiens with CLL have an increased risk of developing second primary malignancies including lung carcinoma, the data about their clinical outcomes are lacking. Parekh et al. retrospectively analyzed patients with simultaneous CLL and lung carcinoma over a 20-year period, and they found that ~2% of patients with CLL actually developed lung carcinoma. The authors claimed that up to 38% of patients will also develop a third neoplasm more likely of the skin (melanoma and basal cell carcinoma), larynx (laryngeal carcinoma) or colon. Currently there are no specific guidelines for concurrent CLL and non-small cell lung carcinoma (NSCLC) treatment. Usually, when the tumors are diagnosed simultaneously, treatment is based to target the most aggressive malignancy, as the clinical outcomes depend on the response of the tumor with the poorest prognosis. For this reason, a multidisciplinary approach is mandatory. Case report: A patient with history of coronary heart disease, myocardial infarction and paroxysmal atrial fibrillation was diagnosed in 2019 (at the age of 71) with B chronic lymphocytic leukemia with bulky tumor (inguinal lymph nodes 8x5 cm), stage B according to Binet, intermediate risk. He was treated with 6 cycles of chemoimmunotherapy (rituximab/cyclofosfamid/fludarabine). In 10/2019 remission was confirmed, but MSCT described tumor in the posterior segment of upper right lung lobe measuring 20x17 mm and bilateral metastases up to 11 mm. Bronchoscopy and biopsy were performed, and EGFR neg, ALK neg, ROS 1 neg, PD-L1>50% adenocarcinoma was confirmed. He was referred to Clinical Hospital Center Osijek where monotherapy with pembrolizumab in a standard dose of 200 mg intravenously was started in 01/2020. Partial remission was confirmed in October 2020. Immunotherapy was discontinued due to development of pneumonitis, dysphagia and severe weight loss (20kg), but without radiologically confirmed disease progression. At that time he was referred to our hospital for further treatment. Gastroscopy has shown erosive gastritis with active duodenal ulcus, Forrest III. Supportive therapy and proton pump inhibitor were introduced. After complete regression of pneumonitis, improvement of general condition and resolution of dysphagia, no signs of lung cancer progression were found and pembrolizumab was reintroduced in 12/2021. Hypothyroidism was diagnosed in 01/2021 and levothyroxine replacement ther apy was started. In 03/2021 he underwent surgical removal of basal cell carcinoma of skin on the right temporal region with lobe reconstruction. From 02/2021, when pembrolizumab was reintroduced, regression in tumor size was continously confirmed with complete recovery of general condition. He was hospitalized for COVID 19 infection in 09/2021, and due to complications pembrolizumab was discontinued till 11/2021. Lung cancer immunotherapy proceeded till 11/2022, when Multidisciplinary team decided to finish pembrolizumab because of CLL relapse. CLL was in remission till August 2022 when due to B symptoms, lymphcytosis, anemia and generalized lymphadenopathy, hematological workup including biopsy of cervical lymph node was performed and CLL/SLL relapse was confirmed. Initially chlorambucil was introduced, but disease was refractory. Based on cytogenetic test results (IGHV unmutated, negative TP53) and due to cardiovascular comorbidity (contraindication for BTK inhibitors) venetoclax and rituximab were started in 01/2023. After just 1 cycle of treatment normal blood count as well as regression of B symptoms and peripheral lymphadenopathy occured, indicating the probability of complete disease remission. In our patient with metastatic lung adenocarcinoma excellent disease control is achieved during 41 month of treatment in first line setting. Furthermore, relapsed/refractory CLL/SLL is currently in confirmed remission. Conclusion(s): Successful treatment of patients with multiple primary malignancies is based on multidisciplinarity, early recognition and management of side effects, treatment of comorbidities with the aim of prolonging life, controlling symptoms of disease and preserving quality of life.

RESUMO

The most common non-Hodgkin's lymphoma (NHL) is diffuse large B-cell lymphoma (DLBCL), an aggressive lymphoma that can be cured with standard frontline chemo-immunotherapy in 60%-70% of patients but with historically poor outcomes for relapsed/refractory disease. Patients with relapsed DLBCL after autologous stem cell transplant (ASCT) or with chemotherapy-refractory disease have a particularly dismal prognosis, with a median overall survival (OS) of only 6 months. Chimeric antigen receptor (CAR) T-cell therapy has significantly improved outcomes for patients with relapsed/refractory large B-cell lymphoma, mantle cell lymphoma and follicular lymphoma, with multiple FDA approved CAR T products now commercially available in many developed world including European countries. Ongoing studies seek to move CAR T cells to earlier lines of therapy and to characterise the efficacy and safety of CAR T-cell approaches in additional lymphoma histologies including relapsed/refractory follicular lymphoma and chronic lymphocytic leukaemias. Other areas of active research address CAR T in combination with other lymphoma-directed therapies, and mechanisms of CAR T resistance. We conducted a retrospective observational study assessing the outcomes of patients referred to our tertiary centre, University College London hospital NHS foundation Trust (UCLH) from January 2018 to December 2022, over a 48-month period. We collected data including patients' demographics, types of lymphomas, prior lines of therapies including stem cell transplantation, bridging therapies as appropriate, complications and overall response rate. We also analysed the communication between teams during the challenging period of the COVID-19 pandemic.

RESUMO

'BSH Global Speakers' was established in 2015 as a core project of the BSH Global Haematology Special Interest Group (SIG). As the project enters its eighth year, we present an update and reflection on the successes and challenges encountered. Initially known as the 'Plenary Speaker Scheme', the project was developed following a stakeholder meeting in 2015 at the inception of the SIG. Haematology colleagues from the UK and low-and middle-income countries (LMIC) came together to discuss how the BSH may be best placed to support haematologists practicing in LMICs. Sharing of expertise and building collaborative networks were identified as key priorities. The 'Plenary Speaker Project' was conceived;BSH haematologists would be supported in delivering plenaries at the meetings of colleagues in LMICs, with the aim that each visit could act as a catalyst for creating networks and developing collaborative projects in education, research, and capacity building. We established a yearly cycle of inviting applications from LMIC societies for a funded speaker at their scientific meetings, selecting the most impactful meetings, then recruiting appropriate UK-based speakers. We place emphasis on the likelihood of ongoing collaborative working or other impacts, for example engagement with local haematology trainees. To date, ten speakers have represented BSH at the meetings of LMIC societies, presenting on diverse topics, from molecularly guided interventions to prevent relapse in AML, to adapting lymphoma treatment strategies for low resource settings. Recently we have opened applications to nurse specialists and scientists, with our first scientific speaker presenting in Thailand May 2023. The COVID-19 pandemic created significant challenges for the project due to the disruption in international travel and the cancellation of many haematology meetings around the globe. We were, however, able to adapt the project to support virtual speakers at meetings in South Africa, Vietnam, and Ghana. Although virtual meetings do not naturally lend themselves to collaborative working, we were pleased that a longer term joint educational program in haemoglobinopathy care has been established with the Vietnamese Society of Haematology as a result of BSH support. The impact of BSH Global Speakers is significant. Even at smaller meetings, speakers will have the ear of the majority of practicing haematologists in a country. From the relationships built between societies and speakers we have seen the development of fellowship programmes, online education programmes, laboratory support, and numerous networks for informal advice in clinical care, research, and more.

RESUMO

Cancer remains one of the most prevalent diseases in the United States and a leading cause of death. Large prospective studies have found significant correlations between dietary intake and cancer. Chronic inflammation promotes pro-cancer inflammatory environments and nutrition can influence inflammation, with the intake of certain food items increasing inflammatory biomarkers. The objective of this research was to explore the relationship between inflammatory diet score measured by the Dietary Inflammatory index and all-cause mortality, cancer-specific mortality, and cancer recurrence among cancer survivors. Web of Science, Medline, CINHAL, and PsycINFO databases were searched to collect potentially eligible sources that focus on dietary inflammation and cancer outcomes. All sources were uploaded to Covidence software and screened by two independent blinded reviewers. The quality of the sources was assessed using the Newcastle Ottawa scale and relevant data was extracted and transferred to the Comprehensive Meta Analysis software and a random effects model was used to perform meta-analysis. Of the 1444 studies imported into the Covidence software, 13 passed all the screening stages and were included in the final analysis. Eight studies reported on pre-diagnosis diet while five others reported on postdiagnosis diet. Five studies reported on colorectal cancer, four on breast cancer, two on ovarian cancer, one on endometrial cancer and one on prostate cancer. Meta-analysis of the studies found that being in the highest postdiagnosis DII score indicating pro-inflammatory diet significantly increased the risk of all-cause death among cancer survivors by 33.5% (HR = 1.335, 95% CI = 1.049, 1.698, n = 6). Analysis did not show a statistically significant association between DII score and cancer mortality or recurrence (HR = 1.097, 95% CI = 0.939, 1.281, n = 6). Analysis by cancer subtype found a significant correlation between postdiagnosis DII score and all-cause mortality among the breast cancer survivors (HR = 1.335, 95% CI = 1.041, 1.711, n = 3) though there were no significant associations between DII and the outcomes of interest from the other cancer types. The meta-analysis concludes that being in the highest postdiagnosis DII score group significantly increased the risk of all-cause death among cancer survivors. This suggests that risk of all-cause mortality could be reduced for cancer survivors by consuming more anti-inflammatory food components and reducing consumption of pro-inflammatory foods. These findings also warrant more research in this field to clarify the relationship between dietary inflammation as measured by the DII and cancer outcomes, particularly cancer-specific mortality.

RESUMO

Background: B-cell lymphoma-2 (Bcl-2) proteins play an important role in multiple myeloma (MM) cell survival and represent an attractive therapeutic target. In prior trials, a subgroup analysis of patients with t(11;14)-positive relapsed/refractory (R/R) MM showed the combination of a Bcl-2 inhibitor, a proteasome inhibitor, and dexamethasone improved progression-free survival with no increased mortality. BGB-11417, a Bcl-2 inhibitor, is more potent and selective than venetoclax. BGB-11417- 105 (NCT04973605) is a phase 1b/2 study assessing the safety and efficacy of BGB-11417 monotherapy, in combination with dexamethasone, or with dexamethasone+carfilzomib in patients with t(11;14)-positive R/R MM. Preliminary safety results for the combination of BGB-11417 + dexamethasone are presented. Method(s): Eligible patients had t(11;14)-positive R/R MM and had been exposed to a proteasome inhibitor, immunomodulatory agent, and anti-CD38 therapy. Patients received 80-, 160-, 320-, or 640-mg BGB-11417 daily with 40-mg dexamethasone weekly until death, intolerability, or disease progression. Dose escalation was guided by a mTPI-2 design and overall review by a safety monitoring committee. Pharmacokinetics (PK) were also assessed. Result(s): As of 1 July 2022, 10 patients were enrolled in the 80-, 160-, and 320-mg (3 patients each) and 640-mg (1 patient) dose-escalation cohorts of BGB-11417 + dexamethasone. The median age was 69 years (range, 52-81) and median prior lines of therapy was 3 (range, 1-5). The median treatment duration was 3.2 months (range, 0.5-6.5). No patients experienced dose-limiting toxicity at any dose level. Three patients died whilst on study: 1 due to COVID-19 complications 157 days after treatment discontinuation (day 208), 1 due to progressive disease 50 days after treatment discontinuation (day 89), and 1 due to COVID-19 whilst on study treatment (day 78). No deaths were associated with study treatment. Two patients experienced Grade >= 3 treatment-emergent adverse events (TEAEs). One patient in the 160-mg cohort experienced Grade 3 increase in liver enzymes and lymphopenia. One patient in the 320-mg cohort experienced Grade 3 lymphopenia. The most common TEAEs were insomnia (50%), fatigue (30%), arthralgia (20%), back pain (20%), lymphopenia (20%), and nausea (20%). BGB-11417 exposure increased dose-dependently from 80 mg to 320 mg with high interpatient PK variability. BGB-11417 exposures after single and multiple doses appeared similar, indicating limited accumulation. Conclusion(s): BGB-11417 plus dexamethasone was generally well-tolerated in patients with R/R MM harbouring t(11;14) at doses <=640 mg. Efficacy data are forthcoming. Recruitment is ongoing in the US, Australia, and New Zealand;the BGB-11417, dexamethasone, and carfilzomib combination arm will open in the future.

RESUMO

Background: Lymphoproliferation is the persistent proliferation of lymphoid cells and it's incidence in inborn errors of immunity varies from 0.7 to 18%. Material(s) and Method(s): This is a retrospective analysis of patients referred to the department of Immunology, B. J. Wadia Hospital for Children, Mumbai between March 2017 to December 2022. Inclusion criteria consisted of 3 months duration of significant lymphadenopathy and/or splenomegaly or history of lymphoma. The clinical characteristics, laboratory and molecular findings of the included patients were analyzed. Result(s): A total of 66 patients were included. There was a male preponderance with male:female ratio of 25:8. Median age of onset of lymphoproliferation was 4.75 years(Range 1 year to 60 years). Splenomegaly was seen in 75%. Infections included recurrent pneumonia (14/66), recurrent ear infections(5/66), COVID(4/66), one episode of pneumonia(6/66), herpes zoster(3/66), recurrent subcutaneous abscess (3/66), abdominal koch(3/66), chronic sinusitis(2/66), dermatophytosis(2/66), esophageal candidiasis(2/66), recurrent malaria(1/66), recurrent varicella(1/66), cryptococcal meningitis(1/66), gram negative sepsis(1/66), BCG adenitis(1/66), pseudomonas osteomyelitis(1/66), impetigo (1/66), pseudomonas urinary tract infection (1/66), chicken pox(1/66), herpes keratitis(1/66), dengue(1/66), Other manifestations included Evans plus phenotype(10/66), Evans phenotype(8/66), Autoimmune hemolytic anemia(5/66), bronchiectasis(5/66), Type 1 diabetes(3/66), hyper reactive airway disease(2/66), inflammatory bowel disease(4/66), autoimmune thrombocytopenia(2/66), stroke(3/66), hemophagocytic lymphohistiocytosis(2/66), hypertriglyceridemia(2/66), hypothyroidism(2/66), celiac disease(1/66), Type 2 diabetes(1/66), autoimmune encephalitis(1/66), autoimmune hepatitis(2/66), anti-parietal cell antibody(1/66), arthritis(1/66), autoimmune enteropathy(1/66), systemic lupus erythromatosus(1/66), primary biliary cirrhosis requiring liver transplant(1/66), nephrotic syndrome(1/66), lymphoedema(1/66), hypersplenism(1/66), recurrent oral ulcers(1/66), gout(1/66), dermatitis(1/66), ovarian teratoma(1/66), alopecia areata(1/66). Hodgkin's lymphoma(HL) was the most common malignancy(9/66), followed by non Hodgkin lymphoma(NHL)(6/66), transformation from NHL to HL(1/66), Burkitt to T-cell lymphoma(1/66), HL to DLBCL(1/66), HL to anaplastic T-cell lymphoma(1/66). EBV driven lymphoproliferation was seen in biopsy of21/66. Genetic testing showed mutations in LRBA(11/66), PIK3CD(5/66), CTLA4(3/66), TET2(2/66), IL2RA (1/66), IL12RB1(1/66), BACH2(1/66), PRKCD(1/66), TNFSFR13B(1/66), TNFAIP3(1/66), FAS(2/66), FASL(1/66), Caspase8(1/66), CARD11(1/66), RTEL1(1/66), AICD(1/66), PIK3R1(1/66), IKBKB(1/66). Treatment included IVIG, chemotherapy, rituximab, sirolimus, abatacept, HSCT. Conclusion(s): All children with persistent lymphoproliferation, with or without autoimmunity and/or infections should be worked up for an underlying monogenic disorder of immune dysregulation. Lymphomas presenting at abnormal site and/or age, relapse and EBV driven lymphomas require further evaluation. Presence of monogenic cause helps in providing targeted therapy.Copyright © 2023 Elsevier Inc.

RESUMO

Introduction: Pediatric brain tumors are the most common tumor in children after hematological malignancies. There is very few data about the epidemiology of pediatric brain tumors in India. Methods - This was a prospective and retrospective study in pediatric patients who had undergone surgery in our institute (JIPMER,Pondicherry). 80 cases were recruited and followed up for minimum follow up period of 1 year. The demographic profile was analysed and IHC markers were done for embroyonal tumors and glioma. Result(s): Pediatric brain tumors was equally distributed among male and females. (1:1) .Mean age of presentation was 10 years . 27.5 % of our cases were embryonal tumors,low grade glioma (16.25 % ) ,high grade glioma ( 12.5 % ) ,ependymoma and craniopharyngioma comprised 15 % of our cases each. Medulloblastoma comprised 23.75 % of cases Out of which 31.5 % had craniospinal metastasis at time of diagnosis. The most common location of SHH pathway medulloblastoma was cerebellar hemisphere and non WNT/non SHH was fourth ventricle. 45.45 % of patients with high grade glioma had recurrence .50 % of ependymoma cases were infratentorial. we had 2 cases of ganglioglioma ,one in the midbrain and other in temporal lobe .Gross total resection was achieved in 30 % ,Subtotal resection in 46.25 % and partial resection in 20 % of our cases. Outcome of patients at the end of 1 year for low and high grade glioma, ependymoma and craniopharyngioma were similar to western literature. Two patients acquired COVID 19 and died while undergoing treatment. Molecular markers like INI1, LIN28 A was highly sensitive and specific for diagnosing atypical teratoid rhabdoid tumor (ATRT) and embryonal tumor with multilayered rosettes (ETMR )respectively. Conclusion(s): Our study emphasizes the need of standardized and systemic cancer registries in India. (Figure Presented).

RESUMO

It is known that inflammatory cytokines exacerbate the persistence and severity of various disease states. Breast cancer is the most frequently detected cancer among women worldwide and our recent studies suggest that the inflammatory state of breast (BrCa) cancer, a byproduct of elevated cytokine expression, induces epigenetic modifications leading to increased recurrence. Ongoing NCI clinical trial data (ClinicalTrials.gov, CCC19, NCT04354701) indicates that among patients with cancer and COVID-19, the mortality is high, and the most prevalent malignancies are of breast [21%] and prostate [16%] origin. Due to the risk of cytokine storm during SARS-CoV-2 infection, it is crucial to identify potential mechanisms of hyperinflammation in BrCa patients. In this study, we have evaluated the level of copy number alteration (CNA) of different inflammatory cytokines including IL-8, IL-1b, IL6, IL-8, GM-CSF, TNF-alpha and many others using cBioportal platform which includes over sixty-nine thousand tumor samples (n>69,000 from 213 different studies) from over 33 different cancers. We found that IL-8 has the highest level of amplification in different breast cancers subtypes. Besides, we also analyzed serum samples from BrCa patients, both recurrent and non-recurrent, by different proteomics methods to identify serum cytokines involved in prognosis and recurrence. Comparative data analysis between non-recurrent BrCa against recurrent BrCa patients identified several proteins with very high significance, mostly proteins associated with epigenetic pathways including HDAC9 (P = 0.0035), HDAC5 (P = 0.013), and HDAC7 (P = 0.020). Besides, we identified differential expression of several pro-inflammatory cytokines and immune regulators (IL-8, IL-4, IL-18, IL-12p70) that were present only in recurrent BrCa patient serum. Our data indicate that inflammatory processes contribute to epigenetic modifications that ultimately play a critical role in breast cancer recurrence. In terms of COVID-19 associated co-morbidity, the already dysregulated inflammatory state of BrCa patients may increase their susceptibility to cytokine-storm, leading to increased severity of COVID-related complications and increased mortality rate. Specifically, we hypothesize that the identified elevated level of IL-8 in BrCa patients may lead to a higher basal level of inflammation and contribute to the risk of attaining cytokine-storm during SARS-CoV-2 infection, making it a valuable target for future studies.

RESUMO

Background Triple-negative breast cancer (TNBC) accounts for ~15% of breast cancer diagnoses but is linked to worse outcomes and comprises a disproportionate number of breast cancer deaths. The TNBC pilot study is a prospective longitudinal study to provide a critical resource for understanding TNBC disease. However, the pandemic impacted the collection of samples. Objective To highlight the impacts of COVID-19 on this longitudinal cancer translational research study including the patient's perspective and to develop recommendations to avoid future disruptions. Methods 389 participants were enrolled in the prospective longitudinal cohort, which collected serial blood samples for up to 5 years. Due to the pandemic, research was curtailed for 6 months due to concerns about patient safety, halting the collection of blood samples. Missed samples and data gaps were documented. To complement this, we initiated a survey capturing the patient perspective on their experience of the study disruption due to COVID. Results 217 enrolled participants missed a blood draw or had a collection outside the study window. 158 patients missed 1 time-point collection, and 59 patients missed >= 2 collections. Of the 217 participants who missed a collection, 6 disease recurrence diagnoses and 3 deaths occurred during research curtailment. The collection of survey responses from participants is ongoing and will be presented at the AACR Annual Meeting. Conclusion Missed samples resulted in irreplaceable data gaps critical to monitoring patient outcomes, and reduced cohort sampling during the pandemic. Our current knowledge of the risks suggests that with proper informed consent, collections could have continued. To mitigate disruption in future clinical studies, clear plans should be part of study design to provide continuity. The participants' experience to be reported will also help researchers understand their issues and help develop policies. (Table Presented).

RESUMO

Introduction: Congenital choledochal cyst (CCC) is a rare cystic dilatation of intrahepatic or extrahepatic biliary ducts. We present a case of a type IVb choledochal cyst presenting as recurrent acute pancreatitis in a young healthy female with initial negative screenings. Case Description/Methods: An 18-year-old-female with a history of COVID-19 presented to the emergency department with one month of persistent abdominal pain, nausea, and vomiting. She was hospitalized once prior for similar symptoms and was diagnosed with acute pancreatitis. This admission, blood work showed elevated lipase, elevated liver enzymes, mild bilirubinemia with a normal lipid panel and urine was significant for infection. She received fluids, antiemetics and was started on prophylactic antibiotics for ascending cholangitis. A right upper quadrant ultrasound ruled out cholelithiasis or acute cholecystitis, but showed dilation of the common bile duct. MRCP confirmed dilation with bulbous termination in the periampullary region diagnosed as type IVb choledochal cyst. Discussion(s): CCCs are rare in Western countries with an incidence between 1 in 100,000 to 150,000. 80% of these cysts are diagnosed in patients under the age of 10. They are difficult to diagnose due to variable clinical presentations. A study of 214 CCC patients demonstrated the most common symptom was abdominal pain, followed by jaundice and fever. When cysts are found in adults, symptoms resemble atypical acute biliary tract disease. Surgical cyst removal may be needed for patients with significant risk factors such as older age and age of symptom onset, due to increased risk of malignant transformation. Longer periods of observation have been documented to be associated with an increased chance of developing late complications, such as anastomotic stricture, biliary calculi and recurrent cholangitis. Type IVb CCCs, as seen in this case, consist of multiple extrahepatic cysts and hepaticojejunostomy is the treatment. This patient's young age and recurrent acute pancreatitis combined with her lab and imaging findings strongly suggest the diagnosis of CCC. The anatomical location of the CCC impeded flow of pancreatic enzymes through the ampulla of vater, leading to recurrent pancreatitis in an otherwise healthy young female. CCC, although very rare, should be considered in the differential of acute pancreatitis when other causes such as gallstones and heavy alcohol consumption cannot be identified, as prompt diagnosis and surgical removal is imperative.

RESUMO

Background/Aims Baricitinib is the most common Janus Kinase inhibitor (JAKi) used in the treatment of rheumatological conditions. Whilst randomised controlled trials have demonstrated the efficacy and safety profile of baricitinib, real-world data on the experience of JAKi use in clinical practice is lacking. The aim of this analysis was to evaluate baricitinib use in a real-world patient population in South London. Methods We looked at two rheumatology departments in South London (St George's Hospital;a tertiary teaching centre and Kingston Hospital;a district general hospital). All patients prescribed baricitinib between January 2017 to June 2022 were included. A retrospective assessment of electronic patient notes was performed to evaluate disease activity (determined by DAS-28 scores at baseline, 3-6 months and presently);adverse effects including side effects, rates of and reasons for discontinuation;and prescribing practice, including previous use of other biological disease modifying anti-rheumatic drugs (bDMARDs). Baseline data including age, gender, co-morbidities and rheumatological diagnoses were also included. Results 233 patients were included in this evaluation, with seropositive rheumatoid arthritis being the most common diagnosis (58%) and with a significant female population (87%). Baricitinib improved average DAS-28 scores from 5.75 (range 3.57-8.3) at baseline to 3.23 (range 0.28-7.49) at 3-6 months post-baricitinib, with the most recent DAS-28 score of 2.90 (range 0.56-6.77). Rates of adverse effects were low as shown in Table 1. Baricitinib was discontinued in 60/233 patients, with average duration to discontinuation of 9.5 months. The most common reasons for discontinuation were: ineffective disease control (28/60), recurrent bacterial infection (5/60), deranged liver function (3/60) and venous thromboembolism (2/60). Eight patients died whilst taking baricitinib. Where documented, the causes of death were Covid-19 (4/8) and malignancy (1/8). 110 out of 233 patients had received other bDMARDs before starting baricitinib. Documented reasons for baricitinib choice over tumour necrosis factor inhibitors (TNFi) included: previous lack of response to TNFi (89/233), contra-indication to TNFi (11/233) and preference of oral route (10/ 233). Conclusion Our real-world study of JAKi use shows that baricitinib is efficacious in the treatment of rheumatological conditions. Moreover, baricitinib is well tolerated, with low rates of adverse effects and subsequent discontinuation. (Table Presented).

RESUMO

Introduction: Autoimmune enteropathy (AIE) is a very rare immune disorder that mainly attacks the gastrointestinal tract by T-cell. The full pathology mechanism is not clear. Typically, characterized by intractable diarrhea and nutritional malabsorption with extra-intestinal manifestations. The proposed diagnostic criteria include small bowel villous atrophy not responding to diet restriction, circulating gut epithelial cell autoantibodies (GECA), and lack of immunodeficiency. We describe a case of AIE with extensive GI involvement, presenting in a 60-year-old patient diagnosed with Type AB thymoma. Case Description/Methods: Our gentleman with a history of Covid-19 complicated with pulmonary embolism and an incidental finding of malignant thymoma. A CT-guided biopsy was consistent with undifferentiated malignant thymoma supported by immunohistochemistry staining. Subsequently, complicated severe diarrhea erupted with significant weight loss. Conservative management, antibiotics, and diet restriction were ineffective. Diagnostic work-up was unremarkable except for anti-enterocytes antibodies (AEA) and anti-goblet cells antibodies (AGA). Bowel biopsy revealed villous blunting, loss of Paneth cells, and minimal intraepithelial lymphocytosis with no evidence of crypt abscesses. Corticosteroid and Octreotide have helped the patient's diarrhea. Thoracoscopy thymectomy performed with radiation therapy due to local and lymphovascular invasion. Discussion(s): AIE characterized by severe villous blunting with the absence of goblet cells and Paneth cells, intraepithelial lymphocytosis, and increased crypt apoptosis. In comparison, graft vs host disease lack crypt abscesses, celiac disease shows increase in the intraepithelial lymphocytosis with intact goblet and Paneth cells, whereas inflammatory bowel disease has intact goblet and Paneth cells, and CVID characterized by absence of plasma cell in the lamina propria. The presences of the GECA are nonspecific but it may help in confirming the diagnosis or may predict the prognosis and recurrence. Only AGA has been reported in IBD. Neither has been observed in celiac disease. The low incidence of AIE and the limited existing literature available on the optimal guidance in management. Oral nutritional supplementation as well as total parenteral nutrition is helpful. The target is to control diarrhea and optimize the nutritional status before surgery. The main treatment is thymectomy.

RESUMO

Background/Aims Through the COVID pandemic there have emerged reports of autoimmunity or new rheumatic diseases presenting in patients after they had COVID-19. This is thought to be caused by cross-reactivity of the COVID-19 spike protein to human antigens. Given the use of mRNA COVID-19 vaccinations which express the spike protein we might expect to see presentation of new rheumatic diseases following their use. We discuss a case where this appears to have occurred. Methods Our patient is a 24-year-old male with mixed phenotype acute leukaemia who had been treated with allogenic stem cell transplant and was currently in remission. He presented with fevers, palpitations, myalgia and bilateral arm and leg swelling. Symptoms began the day after receiving the first dose of an mRNA COVID-19 vaccination (Pfizer/BioNTech.) There were no other symptoms or recent change in medications. Physical examination revealed tender oedema in his forearms, biceps and thighs bilaterally with sparring of the hands. He had reduced power with shoulder (MRC 3/5), elbow (4), wrist (4+) and hip (4) movements. Observations revealed tachycardia and fevers up to 40C. Results Laboratory studies showed markedly elevated C-reactive protein (202), creatinine kinase (6697) and troponin (593) whilst investigations for infection were negative. An autoimmune panel was positive for anti- PM-SCL-75-Ab. An electrocardiogram showed sinus tachycardia. Echocardiogram was normal. Bilateral upper limb dopplers revealed no deep vein thrombus. An MRI of his thighs showed diffuse symmetrical oedema within the muscles, in keeping with an inflammatory myositis. A quadricep muscle biopsy showed evidence of MHC class 1 up-regulation, suggesting an inflammatory process. In addition, there were numerous macrophages evident in the endomysium. While this can be seen in graft-versus-host disease (GVHD), they would usually be found in the perimysium. After discussion between haematology, rheumatology and neurology, this was felt to be a case of vaccine induced myositis and myocarditis. Autoimmune myositis was thought to be less likely due to the relative sparing of the hands and the absence of Raynaud's phenomenon. 1 gram of intravenous methylprednisolone was then given for 3 days. The patient had a marked response with defervescence, improving laboratory markers, improved myalgia and decreased limb swelling. The patient was stepped down to a reducing regime of prednisolone and discharged. Due to relapse whilst weaning he has started on mycophenalate mofetil and rituximab and now continues to improve. Conclusion There are case reports of myositis following COVID-19 vaccination but our patient's case is complicated by the differential diagnosis of GVHD and concurrent myocarditis. Ongoing work is needed to clarify the exact link between vaccination and the presentation of a new inflammatory myositis, but it is important to recognise and start treatment early in order to preserve muscle bulk and ensure recovery.

RESUMO

Ablation includes ethanol injection, radiofrequency ablation (RFA), microwave ablation (MWA), etc. Ablation can be potentially curative, minimally invasive and easily repeatable for recurrence. RFA has been the most widely used ablation technique for liver tumors. The new-generation MWA system incorporating antenna cooling and high-power generation has attracted attention. It can create a more predictable ablation zone and a larger ablation volume in a shorter procedure time. Many high-volume centers have introduced new-generation MWA in Japan. However, many studies failed to show that new-generation MWA is superior to RFA in terms of local control and overall survival. In MWA, clinical data have been insufficient compared with those of RFA. There has been keen competition between surgical resection and ablation for almost 40 years since the era of ethanol injection. In 2021, SURF trial revealed that overall survival and recurrence-free survival were not significantly different between surgical resection and RFA. SURF trial was a multicenter randomized controlled trial in which 49 major centers in Japan enrolled patients with good hepatic function (Child-Pugh scores <= 7) and primary HCC of largest diameter <= 3 cm, and <= 3 nodules during the 6-year period of 2009-2015. The registered patients were followed for at least 5 years. As the result of SURF trial and other comparative studies, the revised Japanese clinical practice guidelines in 2021 treats hepatic resection and ablation equally for patients with <= 3 lesions, <= 3 cm in diameter. Recently, the combination of systemic and locoregional therapies has been attracting much attention. Systemic therapy using molecular targeted agents or immune checkpoint inhibitors is used for advanced HCC which cannot be treated by surgery or ablation. On the other hand, some locoregional therapies, such as hepatectomy and ablation, are potentially curative, but they cannot be indicated for advanced HCC. Combination of both therapies is an approach to improve the prognosis of advanced HCC, which is not indicated for curative treatment. Systemic therapy is used to shrink the tumor, and then locoregional therapies are performed to eradicate it. The combination may build a new strategy for advanced HCC. Ablation is highly operator-dependent. The skills and outcomes are very different from operator to operator. Before the pandemic of COVID-19, we held domestic and international training programs for intermediate and advanced doctors and hands-on seminars for young doctors. These were activities to exchange knowledge and experience and standardize the procedure. During the pandemic, we cannot get together. Since August 2020, we have conducted Japan Ablation Webinar 8 times with a total of 1,566 participants. We have also conducted International Ablation Webinar 4 times with a total of 1,272 participated doctors. Education is important to acquire skills and knowledge for successful ablation. We have established Japan Academy of Tumor Ablation (JATA) this year. There are two triggers. One is that SURF trial revealed that there is no difference between hepatectomy and ablation. The other is that ablation for lung, bone and soft tissue and kidney cancers has become reimbursed with health insurance since this September.
