RESUMO
BACKGROUND: Drug-drug interactions between antiretroviral treatment (ART) and cytostatics may have a negative impact in the prognosis of people with HIV (PWH) and cancer. OBJECTIVE: The objective of this study is to evaluate the impact of the implementation of interdisciplinary management and the type of ART in PWH diagnosed with lymphoid neoplasms. METHODS: This is a multicentric, retrospective observational cohort study including PWH diagnosed with lymphoid neoplasm who started first-line chemotherapy between 2008 and 2020. Demographic, clinical and therapeutic variables were obtained from the electronic medical records and associated with 5-year progression-free survival (PFS) and overall survival (OS) using Cox proportional hazard models. RESULTS: A total of 118 individuals were included. Boosted ART was being used in 55 (46.6%) cases at the time of neoplasm diagnosis. The Infectious Diseases or the Pharmacy Department was consulted before starting chemotherapy in 79/118 (66.9%) cases. Interdisciplinary management resulted in fewer subjects taking boosted ART (17.7% versus 71.8%, Pâ<â0.001) and more subjects using unboosted integrase strand transfer inhibitor-based ART (74.7% versus 7.7%, Pâ<â0.001). The use of boosted ART with chemotherapy was associated with worse 5-year PFS (Pâ=â0.003) and 5-year OS (Pâ=â0.016). There was a trend towards better 5-year PFS and OS when interdisciplinary management was implemented, with significant differences for individuals receiving boosted ART at neoplasm diagnosis (Pâ=â0.0246 and Pâ=â0.0329, respectively). CONCLUSIONS: Our findings underscore the significant impact of the type of ART on the prognosis of PWH undergoing chemotherapy. Encouraging collaborative management between oncologists, pharmacists and HIV teams for these patients enhances PFS and OS rates.
RESUMO
Despite high complete remission (CR) rates with frontline therapy, relapses are frequent in adults with T-cell acute lymphoblastic leukemia (T-ALL) with limited salvage options. We analyzed the outcomes and prognostic factors for CR to salvage therapy and overall survival (OS) of patients with R/R T-ALL included in two prospective measurable residual disease-oriented trials. Seventy-five patients (70 relapsed, 5 refractory) were identified. Relapses occurred in bone marrow, isolated or combined in 50 patients, and in the central nervous system (CNS; isolated or combined) in 20. Second CR was attained in 30/75 patients (40%). Treatment with FLAG-Ida and isolated CNS relapse were independently associated with a higher CR rate after first salvage therapy. The median OS was 6.2 (95% confidence interval [CI], 3.9-8.6) months, with a 4-year OS probability of 18% (95% CI, 9%-27%). No differences in survival were observed according to the treatment with hematopoietic stem cell transplantation in patients in CR after first salvage therapy. Multivariable analysis showed a ≥12-month interval between first CR and relapse, CR after first salvage therapy and isolated CNS relapse as favorable prognostic factors for OS with hazard ratios (HR) (95% CI) of 1.931 (1.109-3.362), 2.958 (1.640-5.334), and 2.976 (1.157-7.655), respectively. This study confirms the poor outcomes of adults with R/R T-ALL among whom FLAG-Ida was the best of the rescue therapies evaluated. Late relapse, CR after first rescue therapy and isolated CNS relapse showed prognostic impact on survival. More effective rescue therapies are needed in adults with R/R T-ALL.

BACKGROUND: BK polyomavirus reactivation can occur following allogeneic hematopoietic stem cell transplantation (allo-HSCT) and may lead to hemorrhagic cystitis (BKPyV-HC). We hypothesized that development of BKPyV-HC is associated with increased mortality post allo-HSCT. METHODS: We retrospectively reviewed data on 133 adult patients (≥18 years old) who underwent allo-HSCT from 2007 until 2014 at Hospital Israelita Albert Einstein in São Paulo, Brazil. RESULTS: Thirty-six patients presented with BKPyV-HC after a median time of 42 days, with a 1-year cumulative incidence probability of 28.9% (95% CI 21.5%-36.7%). In a multivariate Cox model, risk factors for development of BKPyV-HC included younger age, male sex, development of grade 2-4 acute graft-versus-host disease and recipients of umbilical cord blood grafts. Development of grade 3-4 BKPyV-HC (but not grade 1-2) was associated with a decreased overall survival (OS) in a multivariate Cox model (hazard ratio [HR] 7.51, P < 0.0001) and an increased risk of TRM (HR 3.66, P < 0.0001). Grade 3-4 BKPyV-HC was also associated with an increased risk of relapse that did not reach statistical significance (HR 3.01, P = 0.07). Median overall survival (OS) post-BKPyV-HC was 4.7 months, and cidofovir had no impact on survival. CONCLUSION: Development of BKPyV-HC appears to be associated with decreased survival following allo-HSCT.

OBJECTIVES: To analyse clinical outcomes comparing two age groups of patients undergoing allogeneic haematopoietic stem cell transplantation (allo-HSCT), and to identify risk factors associated with older patients' mortality. METHODS: In this retrospective study, the medical charts of all consecutive patients admitted in one hospital for allo-HSCT were reviewed. Overall survival (OS) and other outcomes were compared between patients aged up to 55 years (YG) and older than 55 (EG). RESULTS: From January 2007 to August 2014, 111 adult patients were admitted for allo-HSCT and were included 75 in the YG and 36 in the EG group. The OS rate at D+ 100 was 84% for YG individuals in contrast to 75% in the EG (p = 0.01), and 71% vs. 50% at one year after HSCT (p = 0.01) respectively. Therapy-related mortality (TRM) rates for the YG and EG were, respectively, 14% vs. 17% (p = 0.04) at D+ 100 and 17% vs. 32% (p = 0.04) at one year. Haploidentical donor type and active disease status significantly increased mortality risk in the EG (hazard ratio 2.42; p = 0.018; and 2.04; p = 0.033). CONCLUSION: YG and EG have similar TRM rates early after allo-HSCT, but the elderly had higher TRM during the critical period from 100 days to one year.

INTRODUCTION: The scenario of adult patients with acute lymphoblastic leukemia treated in Brazil has not been well described yet. METHODS: Four hundred patients diagnosed with acute lymphoblastic leukemia from 1981 to 2019, registered in the Brazilian lymphoma and leukemia association (ABRALE) or their caregivers were interviewed by telephone to evaluate patient-reported perceptions of diagnosis, treatment and adverse effects. RESULTS: Overall, 203 were male with a mean age of 15.7 years and median follow-up of 6.2 years. Main presenting symptoms were fever (39 %), bleeding/ecchymosis (38 %), intense fatigue (30 %), and musculoskeletal pain (28 %). The proportion of patients diagnosed within one week of symptoms onset differed between public (17.9 %) and private healthcare (31.1 %; p-value = 0.019). Additionally, diagnostic difficulties were higher in public care: 35 % versus 22.6 % (p-value = 0.034). Only 36 patients were able to report their treatment protocols; from a list of eight reported protocols, the most common were the Brazilian Childhood Cooperative Group for Treatment of Acute Lymphoblastic Leukemia in Children (GBTLI - 10/27.8 %) and Berlin-Frankfurt-Münster (BFM - 8/22.2 %). Seventy patients (17.5 %) required treatment modification, 37.1 % due to severe adverse effects; 21.7 % received short treatment duration (≤6 months) and 16 % proceeded to allogeneic hematopoietic stem cell transplantation with 17/64 (27 %) reporting difficulties in this step, characterized as >3 months delay. Indication for transplantation was related to minimal residual disease and cranial radiotherapy; 41.7 % reported treatment-related adverse effects (range: 1-6), in particular: mood disorders (26.3 %), neurologic deficit (13.8 %), cognitive/memory impairment (12 %), and lung disease (15 %). Risk factors for adverse effects were age, indication of transplantation and living in a large city. Treatment disparities such as diagnostic and transplantation delays remain challenges in these patients. CONCLUSIONS: Urgent interventions are needed to optimize healthcare and reduce adverse effects, especially in adolescent and young adult patients.
RESUMO
INTRODUCTION: Allogeneic Hematopoietic Stem Cell Transplantation (allo-HSCT) patients are exposed to acute and chronic nephrotoxic events (drugs, hypotension, infections, and microangiopathy). The need for hemodialysis (HD) may be associated with high mortality rates. However, the risk factors and clinical impact of HD are poorly understood. AIM: To analyze survival and risk factors associated with HD in allo-HSCT Patients and methods: single-center cohort study 185 (34 HD cases versus 151 controls) consecutive adult allo-HSCT patients from 2007-2019. We performed univariate statistical analysis, then logistic regression and competing risk regression were used to multivariate analysis. Survival was analyzed by Kaplan-Meier and Cox proportional-hazards models. RESULTS: The one-year HD cumulative incidence was 17.6%. Univariate analysis revealed that HD was significantly associated with male gender, age (p 0.056), haploidentical donor, grade II-IV acute GVHD, polymyxin B, amikacin, cidofovir, microangiopathy, septic shock (norepinephrine use) and steroid exposure. The median days of glycopeptides exposure (teicoplanin/vancomycin) was 16 (HD) versus 10 (no HD) (p 0.088). In multivariate analysis, we found: norepinephrine (hazard ratio, HR:3.3; 95% confidence interval, 95%CI:1.2-8.9; p 0.024), cidofovir drug (HR:11.0; 95%CI:4.6- 26.0; p < 0.001), haploidentical HSCT (HR:1.94; 95%CI:0.81-4.65; p 0.14) and Age (HR:1.01; 95%CI: 0.99-1.03; p 0.18) . The HD group had higher mortality rate (HR:6.68; 95% CI: 4.1-10.9; p < 0.001). CONCLUSION: HD was associated with decreased survival in allo-HSCT. Carefully use of nephrotoxic drugs and improving immune reconstitution could reduce severe infections (shock) and patients requiring cidofovir, which taken together may result in lower rates of HD, therefore improving survival.
RESUMO
INTRODUCTION: Despite knowledge advances on extramedullary haematopoiesis (EMH) in thalassemic patients, the real picture remains an open issue. OBJECTIVES: To assess EMH prevalence in patients with thalassemia major (TM) and intermedia (TI), to describe magnetic resonance imaging (MRI) findings and to explore clinical risk factors. METHODS: In this cross-sectional study, images and clinical records of 184 consecutive patients with thalassemia who underwent T2* MRI between 2004 and 2011 were reviewed. Association of EMH with survival was investigated for patients with available follow-up charts. RESULTS: EMH was detected in 16/168 (9.5%) patients with TM (aged 19-49 years) and in 3/16 (18.8%) with TI (aged 36-41 years). Most (88%) had paravertebral thoracic and/or abdominal masses. Age was significantly associated with EMH risk (hazard ratio, [HR] 1.10/year; confidence interval [CI]: 1.03-1.18; p-value < 0.001), while lower pancreatic iron content by T2*MRI (HR: 0.94/ms; CI: 0.89-0.99; p-value = 0.049) was a protective factor. Estimated survival rate was superior for EMH-positive (n = 19) when compared to EMH-negative patients (n = 75) (p-value = 0.013). CONCLUSIONS: The prevalence of EMH was 10.3% (19/184), presented mainly as tumoral masses of 3 to 10 cm. Age was a risk factor for EMH development, while lower pancreatic iron might be a protective factor in this cohort.
RESUMO
INTRODUCTION: Magnetic resonance imaging (MRI) T2* technique is used to assess iron overload in the heart, liver and pancreas of thalassaemic patients. Optimal iron chelation and expected tissue iron response rates remain under investigation. The objective of this study was to analyse serum ferritin and the iron concentration in the heart, liver and pancreas measured by MRI T2*/R2* during regular chelation therapy in a real-world cohort of patients with thalassemia. METHODS: We evaluated thalassaemic patients ≥ 7 years old undergoing chelation/transfusion therapy by MRI and assessed serum ferritin at baseline and follow-up from 2004-2011. RESULTS: We evaluated 136 patients, 92% major thalassaemic, with a median age of 18 years, and median baseline ferritin 2.033ng/ml (range: 59-14,123). Iron overload distribution was: liver (99%), pancreas (74%) and heart (36%). After a median of 1.2 years of follow-up, the iron overload in the myocardium reduced from 2,63 Fe mg/g to 2,05 (p 0.003). The optimal R2* pancreas cut-off was 148 Hertz, achieving 78% sensitivity and 73% specificity. However, when combining the R2* pancreas cut off ≤ 50 Hertz and a ferritin ≤ 1222 ng/ml, we could reach a negative predictive value (NPV) of 98% for cardiac siderosis. Only 28% were undergoing combined chelation at baseline assessment, which increased up to 50% on follow up evaluation. CONCLUSIONS: Chelation therapy significantly reduced cardiac siderosis in thalassaemic patients. In patients with moderate/severe liver iron concentration undergoing chelation therapy, ferritin levels and myocardium iron improved earlier than the liver siderosis.
RESUMO
BACKGROUND: The treatment of acute lymphoblastic leukemia (ALL) in older adults and elderly patients is a challenge, and modern protocols include targeted therapy and immunotherapy in combination with attenuated or minimal chemotherapy. However, frail patients are excluded from these trials, and reports on the outcome of this subgroup of patients are scarce. Our objective was to analyze the outcome of unfit older adults and elderly patients with Philadelphia chromosome-negative ALL included in a prospective trial (ALL-07FRAIL). PATIENTS AND METHODS: Older adults and elderly patients with Charlson Comorbidity Index (CCI) ≥ 4 were included. Induction therapy consisted of vincristine and dexamethasone, and maintenance therapy with mercaptopurine and methotrexate for 2 years. RESULTS: Seventy-two patients with a median age of 67 years (range, 57-89 years) and a median CCI of 5 (range, 4-12) were included. The rates of early withdrawal, early death, resistance, and complete response (CR) were 5%, 10%, 31%, and 54%, respectively. Six patients with CR abandoned the study, 5 died in CR, and 23 relapsed (cumulative relapse incidence 75%). The medians of disease-free and overall survival (OS) were 6.9 months (95% confidence interval [CI], 0.3-13.5 months) and 7.6 months (95% CI, 6.3-8.9 months), respectively. The most frequent toxic events were hematologic (neutropenia 77% and thrombocytopenia 54%, of grade III-IV in all cases). Eastern Cooperative Oncology Group score but not the CCI had significant impact on OS. CONCLUSION: Complete remission with very attenuated chemotherapy can be attained in one-half of older or elderly infirm patients with ALL. These results suggest that some of these patients could benefit from the concomitant or subsequent use of immunotherapy and/or targeted therapy.
