ABSTRACT
Doença de Castleman ou hiperplasia linfoide angiofolicular é uma doença linfoproliferativa, não maligna e relativamente rara. Possui duas variantes: Unicêntrica (DCU) e Multicêntrica (DCM). A DCU manifesta-se em idade mais precoce (em média aos 33 anos), com predominância da variante hialino-vascular e localização preferencial na região da cabeça/pescoço e retroperitôneo. Cerca de 90% dos doentes são assintomáticos e o tratamento de primeira linha consiste na excisão curativa da lesão. Em contra-partida, sua forma multicêntrica envolve um grupo de entidades linfoproliferativas policlonais secundárias a um aumento na secreção de interleucinas, principalmente IL-6. Pode se apresentar de forma idiopática, estar relacionada ao Herpes virus humano (HHV-8) ou a Síndrome POEMS. Quando associada ao HHV-8, manifesta-se clinicamente com sintomas constitucionais (febre, sudorese noturna, perda ponderal), sintomas respiratórios, linfonodomegalias e esplenomegalia. Laboratorialmente pode ter anemia, trombocitopenia, hipoalbuminemia e hipergamaglobulinemia, com aumento de PCR. Apesar da extensa diversidade de manifestações tanto clínico como histopatológicas, há um consenso no “international working group”de que sua forma idiopática (sem HHV8) pode ainda ser subdividida conforme o fenótipo, com ou sem TAFRO - trombocitopenia (T), anasarca (A), febre (F), mielofibrose (R), organomegalia (O). No presente caso, porém, relata-se um paciente com DCM e HHV8 positivo com manifestações que mimetizaram TAFRO. Trata-se de paciente de 28 anos, branco, masculino, HIV positivo com carga viral indetectável e diagnóstico prévio de Sarcoma de Kaposi já tratado. Um ano antes do diagnóstico de DCM, iniciou quadro intermitente de febre, astenia, sintomas respiratórios, gastrointestinais e pancitopenia. Possuia esplenomegalia e linfonodopatias difusas e após biópsia recebeu diagnóstico de Doença de Castleman. O anatomopatológico mostrou-se compatível com variante intermediária entre espectros hialino vascular e plasmacítica. Teve pesquisa de HHV8 positiva na peça e no PCR sérico. Seis meses após este diagnóstico, doença entrou novamente em atividade e foi tratada com corticoterapia e etoposídeo, com resposta mínima. Trocada quimioterapia por esquema alternativo (contendo ciclofosfamida, talidomida e prednisona), cursou com remissões e recaídas, inclusive com recidiva do Sarcoma de Kaposi. Passados 3 anos do diagnóstico de Castleman, paciente manifestou anasarca, ascite, fibrose em biópsia da medula óssea, além de sintomas constitucionais, progressão de linfonodomegalia, esplenomegalia e excesso de IL-6. Assim paciente contemplou todos os cincos critérios maiores do diagnóstico de TAFRO. Na indisponibilidade de rituximabe e anticorpo monoclonal anti-IL-6, optou-se por pulsoterapia com corticoide e CHOP (ciclofosfamida, doxorrubicina, vincristina, prednisona). Após o primeiro ciclo complicou com hematotoxicidade, sepse urinária por KPC e infecção por SARS-CoV-2. Recebeu suporte clínico, com melhora lenta, discreta e momentânea, evoluindo com pancitopenia grave, icterícia. Agregou múltiplas disfunções e foi a óbito, exemplificando como realmente essa etidade rara, ainda pouco compreendida e de difícil diagnóstico se comporta de maneira extremamente agressiva.
ABSTRACT
INTRODUCTION: Patients (pts) with blood disorders are at particular risk for severe infection and death from COVID-19. Factors that contribute to this risk, including cancer treatment, have not been clearly delineated. The ASH RC COVID-19 Registry for Hematology is a public-facing, volunteer registry reporting outcomes of COVID-19 infection in pts with underlying blood disorders. We report a multivariable analysis of the impact of cancer treatment and other key variables on COVID-19 mortality and hospitalization among pts with blood cancer. METHODS: Data were collected between April 1, 2020, and July 2, 2021. All analyses were performed using R version 4.0.2. Multivariable logistic regression explored associations between mortality and seven patient/disease factors previously reported as important to COVID-19 outcome. Independent variables included: age (>60);sex;presence of a major comorbidity (defined as any of heart disease, hypertension, pulmonary disease and/or diabetes);type of hematologic malignancy;estimated prognosis of < 6 months prior to COVID-19;deferral of ICU care;and administration of cancer treatment in the previous year (excluding single agent hydroxyurea). A secondary multivariable logistic regression explored associations between the same variables and hospitalization with COVID-19. RESULTS: We included all pts in the registry with a malignant diagnosis except for 3 patients excluded based on a data sharing agreement (N=1029). Median age category was 50-59y (range <5y to > 90y). The sample was 42% female and 28% had major comorbidities. Types of hematologic malignancies were 354 (34%) acute leukemia/MDS, 255 (25%) lymphoma, 206 (20%) plasma cell dyscrasia (myeloma/amyloid/POEMS), 116 (11%) CLL, 98 (10%) myeloproliferative neoplasm (MPN). Most pts (73%) received cancer treatment during the previous year, 9% had a pre-COVID-19 prognosis of <6months, and 10% deferred ICU care. COVID-19 mortality in the entire cohort was 17%. In multivariable analyses, age > 60 (OR 2.03, 1.31-3.18), male sex (OR 1.69, 1.11 - 2.61), estimated pre-COVID-19 prognosis of less than 6 months (OR 6.16, 3.26 - 11.70) and ICU deferral (OR 10.87, 6.36 - 18.96) were all independently associated with an increased risk of death. Receiving cancer treatment in the year prior to COVID-19 diagnosis and type of hematologic malignancy were not significantly associated with death. In multivariable analyses, age > 60 (OR 2.46, 1.83 - 3.31), male sex (OR 1.34, 1.02 - 1.76), estimated pre-COVID-19 prognosis of < 6 months (OR 4.81, 2.45 - 10.50), presence of a major comorbidity (OR 1.57, 1.15 - 2.16), and cancer treatment in the previous year (OR 1.50, 1.10 - 2.06) were all independently associated with an increased risk of a severe COVID-19 requiring hospitalization. Pts with a MPN or plasma cell dyscrasia and COVID-19 were less likely to require hospitalization for COVID-19 compared to patients with CLL, leukemia/MDS, or lymphoma. CONCLUSIONS: These analyses confirm the negative impact of age > 60, male sex, pre-COVID-19 prognosis of < 6 months, and deferral of ICU care on mortality among patients with hematologic malignancy and COVID-19. We did not observe an increased risk of COVID-19 mortality among pts with COVID-19 who received blood cancer treatment in the previous year, although rate of hospitalization was higher. Pts with some hematologic malignancies (MPN, plasma cell dyscrasias), may experience less severe COVID-19 infections than others.

ABSTRACT
Introduction: Pomalidomide is a third-generation immunomodulatory drug approved for relapsed and/or refractory Multiple Myeloma (RRMM). In the phase 3 OPTIMISMM trial, pomalidomide, bortezomib, and dexamethasone demonstrated superior efficacy in patients with RRMM. PRIME study (CTRI/2019/10/021618) is testing this combination in Newly Diagnosed Multiple Myeloma (NDMM) Aim: To determine safety of Pomalidomide in combination with Bortezomib and dexamethasone (VPD) in NDMM Study design: A prospective, single arm, phase II study from a tertiary center. Both transplant eligible and ineligible patients with NDMM aged between 18-70 years are being recruited in the study. Patients with Plasma cell leukemia, POEMS and amyloidosis were excluded. The regimen consists of weekly Bortezomib 1.3mg/sq.m (subcutaneous), Tab. Pomalidomide 2-4mg once daily for 21days, and Tab Dexamethasone 20mg twice weekly, with the cycle repeating every 28 days, 9-12 cycles. Here we report the adverse events (AE) by NCI CTCAE v5.0, upon recruiting 26 patients, as predetermined in the study. Results: Of the proposed 45-50 patients, 26 patients were enrolled in the study between April 2020 to May 2021 and 23 (88.4%) have completed 4 cycles of VPD. The median age is 55years (18-70), and gender ratio 1:1. At disease presentation, bone lesions were the commonest (96.2%, n=25), IMWG high risk cytogenetics were seen in 42.4% (n=11), RISS-2 in 69.3% (n=18), IgG kappa paraproteinemia in 54% (n=14) patients and ECOG performance score 2-3 in 57.6%(n=15). Ten (38.5%) patients have completed 9 cycles, and 3 underwent auto-transplant (between Cycle 4 & 6). Protocol adherence was 96.1% (25/26 patients). Table-1 shows drug-induced toxicity, hematological toxicities were the commonest. Two patients withdrew consent in view of bortezomib-induced peripheral neuropathy. Serious adverse events (SAE) were reported in 9 (34.6%) patients and were considered unrelated to the regimen by the safety committee (PSVT=1, Bony pain=2, dyspnea=1, pneumonia=1, constipation=1, diarrhea=1, hypotension=1) and one death due to SARS-CoV2 pneumonia. Treatment delays of 2 weeks in 4 patients (SARS-CoV2 = 3, Syncope = 1) After 4 cycles (n=23), 6 (26%) patients were in stringent Complete Response (sCR), 17(74%) in Very Good partial response (VGPR) and 13 (56.5%) are Measurable Residual Disease (MRD) negative. Of 10 patients who completed cycle 9, 9 were MRD negative and 1 showed disease progression. Conclusion: Safety data from the PRIME study demonstrates that VPD regimen has a favorable tolerance profile in patients with NDMM. Early efficacy signals are encouraging, and recruitment continues.

ABSTRACT
Polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS) syndrome is a multisystem autoinflammatory disease due to an underlying plasma cell disorder that lacks a standard treatment strategy because of its rarity. We report a case of relapsed POEMS syndrome successfully treated with a second ambulatory autologous hematopoietic-cell transplantation (AHCT) after a daratumumab desensitization protocol performed during the coronavirus disease (COVID-19) pandemic in a patient with coexisting human immunodeficiency virus (HIV), hepatitis B virus (HBV) and syphilis infections. He is a 37-year old Latin-American male who had been treated with radiation, CyBorD regimen, AHCT and bortezomib therapy before being referred to our service. It was decided to administer daratumumab therapy and subsequently perform the transplant. Placement of central venous access, fluid infusion, conditioning regimen with melphalan and previously cryopreserved autograft infusion were carried out in an outpatient basis. Following second AHCT, the patient demonstrated clinical, VEGF, hematological response and remains SARS-CoV-2 infection-free and in POEMS remission with excellent quality-of-life at last follow up (6 months). We evidenced that thanks to an outpatient transplant program, the best therapeutic modalities can be offered to patients with hematologic malignancies in the context of present or future pandemics. Finally, high-complexity patients with HIV infection should have access to the same treatment strategies as non-infected patients. A second AHCT in the outpatient setting is feasible, safe and highly effective to treat patients with relapsed POEMS syndrome.
