RESUMO

Genetic information has been crucial to understand the pathogenesis of T-cell acute lymphoblastic leukemia (T-ALL) at diagnosis and at relapse, but still nowadays has a limited value in a clinical context. Few genetic markers are associated with the outcome of T-ALL patients, independently of measurable residual disease (MRD) status after therapy. In addition, the prognostic relevance of genetic features may be modulated by the specific treatment used. We analyzed the genetic profile of 145 T-ALL patients by targeted deep sequencing. Genomic information was integrated with the clinicalbiological and survival data of a subset of 116 adult patients enrolled in two consecutive MRD-oriented trials of the Spanish PETHEMA (Programa Español de Tratamientos en Hematología) group. Genetic analysis revealed a mutational profile defined by DNMT3A/ N/KRAS/ MSH2/ U2AF1 gene mutations that identified refractory/resistant patients. Mutations in the DMNT3A gene were also found in the non-leukemic cell fraction of patients with T-ALL, revealing a possible mutational-driven clonal hematopoiesis event to prime T-ALL in elderly. The prognostic impact of this adverse genetic profile was independent of MRD status on day +35 of induction therapy. The combined worse-outcome genetic signature and MRD on day +35 allowed risk stratification of T-ALL into standard or high-risk groups with significantly different 5- year overall survival (OS) of 52% (95% confidence interval: 37-67) and 17% (95% confidence interval: 1-33), respectively. These results confirm the relevance of the tumor genetic profile in predicting patient outcome in adult T-ALL and highlight the need for novel gene-targeted chemotherapeutic schedules to improve the OS of poor-prognosis T-ALL patients.

RESUMO

INTRODUCTION: The prognosis of relapsed B cell precursor acute lymphoblastic leukemia (B-ALL) is poor and few patients can be successfully rescued with conventional therapies. Inotuzumab ozogamicin (IO), an antibody against the CD22 antigen linked to calicheamicin, has been approved as a rescue treatment in relapsed/refractory (R/R) B-ALL. PATIENTS AND METHODS: This was an observational, retrospective, multicenter study of adult patients included in the Spanish program of compassionate use of IO in centers from the PETHEMA group (Programa Español de Tratamientos en Hematología). RESULTS: Thirty-four patients with a median age of 43 years (range, 19-73) were included. Twenty patients (59%) were refractory to the last treatment, IO treatment was given as ≥3rd salvage treatment in 25 patients (73%) and 20 patients (59%) received allogeneic hematopoietic stem cell transplantation before IO treatment. After a median of 2 cycles of IO, 64% of patients achieved complete response (CR)/complete response with incomplete recovery. The median response duration, progression-free survival and overall survival (OS) were 4.7 (95%CI, 2.4-7.0 months), 3.5 (95%CI, 1.0-5.0 months) and 4 months (95%CI, 1.9-6.1 months) respectively, with better OS for patients with relapsed B-ALL versus refractory disease (10.4 vs. 2.5 months, respectively) (p = .01). There was a trend for better OS for patients with first CR duration >12 months (7.2 months [95%CI, 3.2-11.2] vs. 3 months [95% CI, 1.8-4.2] respectively) (p = .054). There was no sinusoidal obstruction syndrome (SOS) event during IO treatment, but three patients (9%) developed grade 3-4 SOS during alloHSCT after IO treatment. CONCLUSIONS: Our study showed slightly inferior outcomes of the pivotal trial probably due to poorer risk factors and late onset of IO therapy of recruited patients. Our results support early use of IO in relapsed/refractory ALL patients.

RESUMO

OBJECTIVES: The goal of this work was to study the relationship between presence of varicocele and testosterone serum levels in adulthood. METHODS: A comparative, cross-sectional study of 387 men who consulted for erectile dysfunction. Age, body mass index (BMI), diabetes (DM), and presence of varicocele were related to testosterone levels through uni- and multi-variate analysis. RESULTS: A total of 248 cases (70.8%) had no varicocele, 46 (13.1%) had grade I varicocele, 36 (10.3%) grade II, and 20 (5.7%) grade III. The mean total testosterone levels were 4.77 ng/mL in the non-varicocele group and 4.34 ng/mL in the varicocele group (p = .91), while free testosterone levels were 69.81 and 73.24 pg/mL (p = .18), respectively. In the multivariate analysis, BMI> = 30 was related to low total testosterone levels (OR: 2.94, p < .001) and low free testosterone (OR: 2.01, p = .01), while advanced age associated with low levels of free testosterone (OR: 1.04, p < .001). CONCLUSIONS: We were not able to establish a relationship between the presence of varicocele and decreased serum testosterone levels. Other factors already described, such as obesity and age, were related to low levels of total and free testosterone.

RESUMO

We report data from a prospective, observational study (ZAGAL) evaluating miglustat 100mg three times daily orally. in treatment-naïve patients and patients with type 1 Gaucher Disease (GD1) switched from previous enzyme replacement therapy (ERT). Clinical evolution, changes in organ size, blood counts, disease biomarkers, bone marrow infiltration (S-MRI), bone mineral density by broadband ultrasound densitometry (BMD), safety and tolerability annual reports were analysed. Between May 2004 and April 2016, 63 patients received miglustat therapy; 20 (32%) untreated and 43 (68%) switched. At the time of this report 39 patients (14 [36%] treatment-naïve; 25 [64%] switch) remain on miglustat. With over 12-year follow-up, hematologic counts, liver and spleen volumes remained stable. In total, 80% of patients achieved current GD1 therapeutic goals. Plasma chitotriosidase activity and CCL-18/PARC concentration showed a trend towards a slight increase. Reductions on S-MRI (p=0.042) with an increase in BMD (p<0.01) were registered. Gastrointestinal disturbances were reported in 25/63 (40%), causing miglustat suspension in 11/63 (17.5%) cases. Thirty-eight patients (60%) experienced a fine hand tremor and two a reversible peripheral neuropathy. Overall, miglustat was effective as a long-term therapy in mild to moderate naïve and ERT stabilized patients. No unexpected safety signals were identified during 12-years follow-up.

RESUMO

BACKGROUND: Erectile dysfunction (ED) is associated with cardiovascular events. High-sensitivity C-reactive protein (hsCRP) is a cardiovascular risk marker. The aim of this study is to determine whether hsCRP is useful in evaluating ED. METHODS: In 121 patients with ED, age, ED type and severity, time since onset of ED, weight, height, BMI, body fat percentage, waist and hip circumference, hsCRP and hormone profile were studied. Patients were classified as low or moderate-high cardiovascular risk based on hsCRP levels. A descriptive and univariate study was performed. A logistic regression was used to establish factors associated with low versus moderate-high cardiovascular risk and hsCRP. RESULTS: Most patients had moderate-severe ED (70%). 74% had a moderate-high cardiovascular risk based on hsCRP levels, and 33.9 and 34.7% had hypogonadism according to total (TT) and free testosterone. In the univariate analysis, a relationship between hsCRP and TT and physical examination variables was observed (p < 0.05). In the multivariate analysis, TT was found to be a predictor (OR: 0.676; 95% CI: 0.491-0.029). Higher cardiovascular risk was found in the hypogonadic group (OR: 5.51; 95% CI: 1.185-25.662) and waist- to-hip ratio (p = 0.008; OR: 1.361; 95% CI: 1.075-1.612). CONCLUSIONS: A majority of patients with ED have high cardiovascular risk based on hsCRP levels and there is an association with hypogonadism and obesity.

RESUMO

PURPOSE: To describe the contrast-enhanced ultrasound (CEUS) features of liver and biliary lesions related to hepatic artery thrombosis in adult patients with orthotopic liver transplantation. METHODS: Gray-scale ultrasound (US), Doppler US, and CEUS using a hexafluoride-based US contrast media were performed on a series of eight patients with liver transplantation and hepatic artery thrombosis. RESULTS: Six of the cases presented infarctions, seen as parenchymal geographic areas of lack of enhancement. Biliary necrosis, seen as nonenhancing periportal cuff, was seen in one case. Infected biloma, seen as a nonenhancing hilar collection, was present in two cases. Infarction and biloma coexisted in one patient. Two abscesses were seen as a late complication in one case. One of them was seen as a typical necrotic abscess with a central nonenhancing area and peripheral rim enhancement higher than the surrounding liver. The other one was seen as a partially liquefied abscess. CONCLUSION: CEUS was useful to diagnose lesions related to hepatic artery thrombosis in liver transplantation. It enabled distinguishing between them and to define their size and extension better than conventional gray-scale US.

RESUMO

Pediatric invasive fungal rhinosinusitis (PIFR) is a rapidly progressive, potentially fatal disease. Previous medical literature demonstrates that its early diagnosis significantly reduces the risk of mortality in these patients. This study aims to present an updated clinical algorithm for optimized diagnosis and management of PIFR. A comprehensive review was conducted with only original, full-text articles published in English and Spanish from Cochrane Library, Pub-Med/MEDLINE, Embase, Scopus, and Google Scholar between January 2010 and June 2022. Relevant information was extracted and then integrated to develop a clinical algorithm for a proper diagnosis and management of PIFR.

RESUMO

Imaging is required if complication is suspected in acute pyelonephritis to assess the nature and extent of the lesions, and to detect underlying causes. The current imaging modality of choice in clinical practice is computed tomography. Because of associated radiation and potential nephrotoxicity, CEUS is an alternative that has been proven to be equally accurate in the detection of acute pyelonephritis renal lesions. The aims of this study of 48 patients are to describe in detail the CEUS findings in acute pyelonephritis, and to determine if abscess and focal pyelonephritis may be distinguished. Very characteristic morphologic and temporal patterns of enhancement are described. These allow differentiation of focal pyelonephritis from renal abscess, and detection of tiny suppurative foci within focal pyelonephritis. The detection of abscesses is important because follow-up in 25 patients revealed a longer clinical course. Typical pyelonephritis CEUS features permit distinction from other renal lesions. As a whole, CEUS is an excellent tool in the work-up of complicated acute pyelonephritis, so it may be considered as the imaging technique of choice in the evaluation and follow-up of these patients who frequently are very young, so as to minimise radiation exposure.

RESUMO

BACKGROUND: Factors affecting outcomes of SARS-CoV-2 infection in people living with HIV are unclear. We assessed the factors associated with SARS-CoV-2 diagnosis and severe outcomes among people living with HIV. METHODS: We did a retrospective cohort study using data from the PISCIS cohort of people with HIV in Catalonia (Spain) between March 1 and Dec 15, 2020. We linked PISCIS data with integrated health-care, clinical, and surveillance registries through the Public Data Analysis for Health Research and Innovation Program of Catalonia (PADRIS) to obtain data on SARS-CoV-2 diagnosis, chronic comorbidities, as well as clinical and mortality outcomes. Participants were aged at least 16 years in care at 16 hospitals in Catalonia. Factors associated with SARS-CoV-2 diagnoses and severe outcomes were assessed using univariable and multivariable Cox regression models. We estimated the effect of immunosuppression on severe outcomes (hospital admission for >24 h with dyspnoea, tachypnoea, hypoxaemia, asphyxia, or hyperventilation; or death) using Kaplan-Meier survival analysis. FINDINGS: We linked 20 847 (72·8%) of 28 666 participants in the PISCIS cohort with PADRIS data; 13 142 people had HIV. 749 (5·7%) people with HIV were diagnosed with SARS-CoV-2: their median age was 43·5 years (IQR 37·0-52·7), 131 (17·5%) were female, and 618 (82·5%) were male. 103 people with HIV (13·8%) were hospitalised, seven (0·9%) admitted to intensive care, and 13 (1·7%) died. SARS-CoV-2 diagnosis was more common among migrants (adjusted hazard ratio 1·55, 95% CI 1·31-1·83), men who have sex with men (1·42, 1·09-1·86), and those with four or more chronic comorbidities (1·46, 1·09-1·97). Age at least 75 years (5·2, 1·8-15·3), non-Spanish origin (2·1, 1·3-3·4), and neuropsychiatric (1·69, 1·07-2·69), autoimmune disease (1·92, 1·14-3·23), respiratory disease (1·84, 1·09-3·09), and metabolic disease (2·59, 1·59-4·23) chronic comorbidities were associated with increased risk of severe outcomes. A Kaplan-Meier estimator showed differences in the risk of severe outcomes according to CD4 cell count in patients with detectable HIV RNA (p=0·039) but no differences were observed in patients with undetectable HIV RNA (p=0·15). INTERPRETATION: People living with HIV with detectable HIV viraemia, chronic comorbidities, and some subpopulations could be at increased risk of severe outcomes from COVID-19. These groups should be prioritised in clinical management and SARS-CoV-2 vaccination programmes. FUNDING: Fundació "la Caixa".

RESUMO

Acute myeloid leukemia (AML) with intermediate risk cytogenetics (IRcyto) comprises a variety of biological entities with distinct mutational landscapes that translate into differential risks of relapse and prognosis. Optimal postremission therapy choice in this heterogeneous patient population is currently unsettled. In the current study, we compared outcomes in IRcyto AML recipients of autologous (autoSCT) (n = 312) or allogeneic stem cell transplantation (alloSCT) (n = 279) in first complete remission (CR1). Molecular risk was defined based on CEBPA, NPM1, and FLT3-ITD mutational status, per European LeukemiaNet 2017 criteria. Five-year overall survival (OS) in patients with favorable molecular risk (FRmol) was 62% (95% confidence interval [CI], 50-72) after autoSCT and 66% (95% CI, 41-83) after matched sibling donor (MSD) alloSCT (P = .68). For patients of intermediate molecular risk (IRmol), MSD alloSCT was associated with lower cumulative incidence of relapse (P < .001), as well as with increased nonrelapse mortality (P = .01), as compared to autoSCT. The 5-year OS was 47% (95% CI, 34-58) after autoSCT and 70% (95% CI, 59-79) after MSD alloSCT (P = .02) in this patient subgroup. In a propensity-score matched IRmol subcohort (n = 106), MSD alloSCT was associated with superior leukemia-free survival (hazard ratio [HR] 0.33, P = .004) and increased OS in patients alive 1 year after transplantation (HR 0.20, P = .004). These results indicate that, within IRcyto AML in CR1, autoSCT may be a valid option for FRmol patients, whereas MSD alloSCT should be the preferred postremission strategy in IRmol patients.

RESUMO

Out of 956, there were 95 (10%) CD56+ APL patients treated with PETHEMA ATRA and chemotherapy. CD56+ expression was associated with high WBC, BCR3 isoform, and co-expression of CD2, CD34, CD7, HLA-DR, CD15, and CD117 antigens. CD56+ vs CD56- APL presented higher induction death rate (16% vs 8%, p = .02) and 5-years cumulative incidence of relapse (33% versus 10%, p = .006), irrespectively of the Sanz score (low-risk 47% versus 5%, p < .001; intermediate 23% versus 7%, p < .001; and high-risk 42% versus 21%, p = .007). In the multivariate analysis, CD56 + (p < .0001), higher relapse-risk score (p = .001), and male gender (p = .05) retained the independent predictive value. CD56+ APL also showed a greater risk of CNS relapse (6% versus 1%, p < .001) and lower 5-year OS (75% versus 83%, p = .003). The AIDA-based LPA2012 trial, with an intensified consolidation schedule for CD56+ APL, will elucidate whether an intensified consolidation schedule could mitigate the relapse rate in this setting.

RESUMO

BACKGROUND: We assessed the strategy of substituting nevirapine, efavirenz, or abacavir for a protease inhibitor in patients infected with human immunodeficiency virus type 1 (HIV-1) in whom virologic suppression had been achieved. METHODS: We randomly assigned 460 adults who were taking two nucleoside reverse-transcriptase inhibitors and at least one protease inhibitor and whose plasma HIV-1 RNA levels had been less than 200 copies per milliliter for at least the previous six months to switch from the protease inhibitor to nevirapine (155 patients), efavirenz (156), or abacavir (149). The primary end point was death, progression to the acquired immunodeficiency syndrome, or an increase in HIV-1 RNA levels to 200 copies or more per milliliter. RESULTS: At 12 months, the Kaplan-Meier estimates of the likelihood of reaching the end point were 10 percent in the nevirapine group, 6 percent in the efavirenz group, and 13 percent in the abacavir group (P=0.10 according to an intention-to-treat analysis). HIV-1 RNA could be amplified in 21 of the 29 patients in whom virologic failure developed during treatment with study medication (72 percent), and resistance mutations to the study medication and to at least one of the nucleoside reverse-transcriptase inhibitors in the regimen that failed were detected in all but 1 of the 21 patients. Twenty-three of the 29 patients with virologic failure during treatment with study medication had received prior suboptimal therapy with nucleoside reverse-transcriptase inhibitors. Fewer patients in the abacavir group (6 percent) than in the nevirapine group (17 percent) or the efavirenz group (17 percent) discontinued the study medication because of adverse events (P=0.01). The proportion of patients with fasting lipid levels warranting therapeutic intervention decreased significantly in the abacavir group, but the prevalence of clinical lipodystrophy did not change significantly in the three groups. CONCLUSIONS: When therapy was switched from a protease inhibitor to nevirapine, efavirenz, or abacavir in patients with virologic suppression, there was a trend toward a higher rate of virologic failure among those given abacavir.

RESUMO

Arthropods are the most diverse taxonomic group of terrestrial eukaryotes and are sensitive to physical alterations in their environment such as those caused by forestry. With their enormous diversity and physical omnipresence, arthropods could be powerful indicators of the effects of disturbance following forestry. When arthropods have been used to measure the effects of disturbance, the total diversity of some groups is often found to increase following forestry. However, these findings are frequently derived using a coarse taxonomic grain (family or order) to accommodate for various taxonomic impediments (including cryptic diversity and poorly resourced taxonomists). Our intent with this work was to determine the diversity of arthropods in and around Algonquin Park, and how this diversity was influenced by disturbance (in this case, forestry within the past 25 years). We used DNA barcode-derived diversity estimates (Barcode Index Number (BIN) richness) to avoid taxonomic impediments and as a source of genetic information with which we could conduct phylogenetic estimates of diversity (PD). Diversity patterns elucidated with PD are often, but not always congruent with taxonomic estimates-and departures from these expectations can help clarify disturbance effects that are hidden from richness studies alone. We found that BIN richness and PD were greater in disturbed (forested) areas, however when we controlled for the expected relationship between PD and BIN richness, we found that cut sites contained less PD than expected and that this diversity was more phylogenetically clustered than would be predicted by taxonomic richness. While disturbance may cause an evident increase in diversity, this diversity may not reflect the full evolutionary history of the assemblage within that area and thus a subtle effect of disturbance can be found decades following forestry.

RESUMO

The purpose of this study was to examine alcohol consumption in different stages of the estrogen treatment. Three groups of castrated male Wistar rats were used. One group was treated with 5 microg of estradiol benzoate (E) per day per rat for 6 days and oil from days 7 to 12 (EO group). The second group was treated with oil for 6 days and E from days 7 to 12 (OE) and the third with E for 12 consecutive days (EE). The three groups were exposed to a choice of both water and ethanol (10%) before treatment (PreT), from days 7 to 12 of the oil or the E treatment (T2), and during 6 additional days in the post-treatment period (PosT). Alcohol was not available from days 1 to 6 of the oil or the E treatment (T1). Alcohol consumption in the EO group during T2 was higher than in PreT and PosT periods and all periods in the other two groups. In contrast, alcohol consumption during T2 was significantly lower than during the PreT of the OE group and T2 of the EE group. At the same time in the EE group, alcohol intake in the T2 was higher than in the PreT and the PosT periods. These results reveal the opposite effects of estrogen treatment on alcohol consumption, which apparently depended on the physiological conditions produced by the temporal course of hormone treatment.

RESUMO

OBJECTIVE: To present the therapeutic management of severe complications related to postoperative mitomycin extravasation. METHODS: Description of clinical cases, medical and surgical management and pathologic results of surgical specimens. RESULTS: We report two cases of patients with extravesical mitomycin leakage after postoperative instillation. No bladder perforation was evident during tumor surgery. In both cases radical cystectomy was required. CONCLUSIONS: Postoperative mitomycin instillation may have undesirable consequences. The possible problems derived from its administration must be known, and each case must be individualized before administering this chemotherapy.

RESUMO

The role of allogeneic hematopoietic cell transplant (allo-HCT) in elderly patients with acute lymphoblastic leukemia (ALL) is unclear. We conducted a prospective study including 110 homogeneously treated patients with ALL aged 50-70 years. Their outcomes were analyzed by intention-to-treat on a donor-versus-no donor basis. Fifty-five patients (50%) underwent human leukocyte antigen (HLA) typing and were considered potential allo-HCT candidates, although only 25 (23%) eventually received an allo-HCT. Among potential allo-HCT candidates, patients with (n = 28) and without (n = 27) an HLA-identical sibling showed similar leukemia-free survival, overall survival (OS) and relapse risk, and the only variable associated with a better outcome was achievement of first complete remission (CR1) after induction therapy. Among the 25 patients who actually received an allo-HCT, the 4-year non-relapse mortality and OS were 42% (95% confidence interval 31-53%) and 37% (95% confidence interval 27-47%), respectively. In conclusion, having an HLA-identical sibling donor was not associated with a better outcome in patients with ALL aged 50-70 years.

RESUMO

BACKGROUND: Comprehensive biotic surveys, or 'all taxon biodiversity inventories' (ATBI), have traditionally been limited in scale or scope due to the complications surrounding specimen sorting and species identification. To circumvent these issues, several ATBI projects have successfully integrated DNA barcoding into their identification procedures and witnessed acceleration in their surveys and subsequent increase in project scope and scale. The Biodiversity Institute of Ontario partnered with the rare Charitable Research Reserve and delegates of the 6th International Barcode of Life Conference to complete its own rapid, barcode-assisted ATBI of an established land trust in Cambridge, Ontario, Canada. NEW INFORMATION: The existing species inventory for the rare Charitable Research Reserve was rapidly expanded by integrating a DNA barcoding workflow with two surveying strategies - a comprehensive sampling scheme over four months, followed by a one-day bioblitz involving international taxonomic experts. The two surveys resulted in 25,287 and 3,502 specimens barcoded, respectively, as well as 127 human observations. This barcoded material, all vouchered at the Biodiversity Institute of Ontario collection, covers 14 phyla, 29 classes, 117 orders, and 531 families of animals, plants, fungi, and lichens. Overall, the ATBI documented 1,102 new species records for the nature reserve, expanding the existing long-term inventory by 49%. In addition, 2,793 distinct Barcode Index Numbers (BINs) were assigned to genus or higher level taxonomy, and represent additional species that will be added once their taxonomy is resolved. For the 3,502 specimens, the collection, sequence analysis, taxonomic assignment, data release and manuscript submission by 100+ co-authors all occurred in less than one week. This demonstrates the speed at which barcode-assisted inventories can be completed and the utility that barcoding provides in minimizing and guiding valuable taxonomic specialist time. The final product is more than a comprehensive biotic inventory - it is also a rich dataset of fine-scale occurrence and sequence data, all archived and cross-linked in the major biodiversity data repositories. This model of rapid generation and dissemination of essential biodiversity data could be followed to conduct regional assessments of biodiversity status and change, and potentially be employed for evaluating progress towards the Aichi Targets of the Strategic Plan for Biodiversity 2011-2020.
