Does the Use of Immunosuppressive Drugs Impact on SARS-CoV-2 Infection Outcome? Data From A National Cohort of Patients With Immune-Mediated Inflammatory Diseases (SAR-COVID Registry).

BACKGROUND/OBJECTIVE: This study describes the impact of immunomodulatory and/or immunosuppressive (IM/IS) drugs in the outcomes of COVID-19 infection in a cohort of patients with immune-mediated inflammatory diseases (IMIDs). METHODS: Adult patients with IMIDs with a confirmed SARS-CoV-2 infection were included. Data were reported by the treating physician between August 13, 2020 and July 31, 2021. Sociodemographic data, comorbidities, and DMARDs, as well as clinical characteristics, complications, and treatment of the SARS-CoV-2 infection, were recorded. Descriptive analysis and multivariable logistic regression models were carried out. RESULTS: A total of 1672 patients with IMIDs were included, of whom 1402 were treated with IM/IS drugs. The most frequent diseases were rheumatoid arthritis (47.7%) and systemic lupus erythematosus (18.4%). COVID-19 symptoms were present in 95.2% of the patients. A total of 461 (27.6%) patients were hospitalized, 8.2% were admitted to the intensive care unit, and 4.4% died due to COVID-19.Patients without IM/IS treatment used glucocorticoids less frequently but at higher doses, had higher levels of disease activity, were significantly older, were more frequently hospitalized, admitted to the intensive care unit, and died due to COVID-19. After adjusting for these factors, treatment with IM/IS drugs was not associated with a worse COVID-19 outcome (World Health Organization-Ordinal Scale ≥5) (odds ratio, 1.24; 95% confidence interval, 0.73-2.06). CONCLUSIONS: SAR-COVID is the first multicenter Argentine registry collecting data from patients with rheumatic diseases and SARS-CoV-2 infection. After adjusting for relevant covariates, treatment with IM/IS drugs was not associated with severe COVID-19 in patients with IMIDs. STUDY REGISTRATION: This study has been registered in ClinicalTrials.gov under the number NCT04568421.

Radiation-induced lung injury: current evidence.

Chemo-radiotherapy and systemic therapies have proven satisfactory outcomes as standard treatments for various thoracic malignancies; however, adverse pulmonary effects, like pneumonitis, can be life-threatening. Pneumonitis is caused by direct cytotoxic effect, oxidative stress, and immune-mediated injury. Radiotherapy Induced Lung Injury (RILI) encompasses two phases: an early phase known as Radiation Pneumonitis (RP), characterized by acute lung tissue inflammation as a result of exposure to radiation; and a late phase called Radiation Fibrosis (RF), a clinical syndrome that results from chronic pulmonary tissue damage. Currently, diagnoses are made by exclusion using clinical assessment and radiological findings. Pulmonary function tests have constituted a significant step in evaluating lung function status during radiotherapy and useful predictive tools to avoid complications or limit toxicity. Systemic corticosteroids are widely used to treat pneumonitis complications, but its use must be standardized, and consider in the prophylaxis setting given the fatal outcome of this adverse event. This review aims to discuss the clinicopathological features of pneumonitis and provide practical clinical recommendations for prevention, diagnosis, and management.

Nitroglycerin Plus Whole Intracranial Radiation Therapy for Brain Metastases in Patients With Non-Small Cell Lung Cancer: A Randomized, Open-Label, Phase 2 Clinical Trial.

PURPOSE: Hypoxia has been associated with chemoradioresistance secondary to vascular endothelial growth factor receptor induced by hypoxia-induced factor (HIF). Nitroglycerin (NTG) can reduce HIF-1 in tissues, and this may have antiangiogenic, proapoptotic, and antiefflux effects. Particularly, epidermal growth factor-mutated (EGFRm) tumor cell lines have been shown to overexpress both vascular endothelial growth factor and HIF. In this phase 2 study, we evaluated the effect of transdermal NTG plus whole brain radiation therapy (WBRT) in patients with non-small cell lung cancer (NSCLC) with brain metastases (BM). METHODS: This was an open-label, phase 2 clinical trial with 96 patients with NSCLC and BM. Patients were randomized 1:1 to receive NTG plus WBRT (30 Gy in 10 fractions) or WBRT alone. The primary endpoint was intracranial objective response rate (iORR) evaluated 3 months posttreatment. NTG was administered using a transdermal 36-mg patch from Monday through Friday throughout WBRT administration (10 days). The protocol was retrospectively registered at ClinicalTrials.gov (NCT04338867). RESULTS: Fifty patients were allocated to the control group, and 46 were allocated to the experimental group (NTG); among these, 26 (52%) had EGFRm in the control group and 21 (45.7%) had EGFRm in the NTG arm. In terms of the iORR, patients in the NTG group had a significantly higher response compared with controls (56.5% [n = 26/46 evaluable patients] vs 32.7% [n = 16/49 evaluable patients]; relative risk, 1.73; 95% confidence interval [CI], 1.08-2.78; P = .024). Additionally, patients who received NTG + WBRT had an independently prolonged intracranial progression-free survival (ICPFS) compared with those who received WBRT alone (27.7 vs 9.6; hazard ratio [HR], 0.5; 95% CI, 0.2-0.9; P = .020); this positively affected overall progression-free survival among patients who received systemic therapy (n = 88; HR, 0.5; 95% CI, 0.2-0.9; P = .043). The benefit of ICPFS (HR, 0.4; 95% CI, 0.2-0.9; P = .030) was significant in the EGFRm patient subgroup. No differences were observed in overall survival. A significantly higher rate of vomiting presented in the NTG arm of the study (P = .016). CONCLUSIONS: The concurrent administration of NTG and radiation therapy improves iORR and ICPFS among patients with NSCLC with BM. The benefit in ICPFS is significant in the EGFRm patient subgroup.

Sociodemographic and clinical factors associated with poor COVID-19 outcomes in patients with rheumatic diseases: data from the SAR-COVID Registry.

BACKGROUND/OBJECTIVE: This study aims to describe the course and to identify poor prognostic factors of SARS-CoV-2 infection in patients with rheumatic diseases. METHODS: Patients ≥ 18 years of age, with a rheumatic disease, who had confirmed SARS-CoV-2 infection were consecutively included by major rheumatology centers from Argentina, in the national, observational SAR-COVID registry between August 13, 2020 and July 31, 2021. Hospitalization, oxygen requirement, and death were considered poor COVID-19 outcomes. RESULTS: A total of 1915 patients were included. The most frequent rheumatic diseases were rheumatoid arthritis (42%) and systemic lupus erythematosus (16%). Comorbidities were reported in half of them (48%). Symptoms were reported by 95% of the patients, 28% were hospitalized, 8% were admitted to the intensive care unit (ICU), and 4% died due to COVID-19. During hospitalization, 9% required non-invasive mechanical ventilation (NIMV) or high flow oxygen devices and 17% invasive mechanical ventilation (IMV). In multivariate analysis models, using poor COVID-19 outcomes as dependent variables, older age, male gender, higher disease activity, treatment with glucocorticoids or rituximab, and the presence of at least one comorbidity and a greater number of them were associated with worse prognosis. In addition, patients with public health insurance and Mestizos were more likely to require hospitalization. CONCLUSIONS: In addition to the known poor prognostic factors, in this cohort of patients with rheumatic diseases, high disease activity, and treatment with glucocorticoids and rituximab were associated with worse COVID-19 outcomes. Furthermore, patients with public health insurance and Mestizos were 44% and 39% more likely to be hospitalized, respectively. STUDY REGISTRATION: This study has been registered in ClinicalTrials.gov under the number NCT04568421. Key Points • High disease activity, and treatment with glucocorticoids and rituximab were associated with poor COVID-19 outcome in patients with rheumatic diseases. • Some socioeconomic factors related to social inequality, including non-Caucasian ethnicity and public health insurance, were associated with hospitalization due to COVID-19.

Prophylactic Cranial Irradiation Reduces Brain Metastases and Improves Overall Survival in High-Risk Metastatic Non-Small Cell Lung Cancer Patients: A Randomized phase 2 Study (PRoT-BM trial).

PURPOSE: To date, studies regarding the use of prophylactic cranial irradiation (PCI) versus standard of care (SoC) for patients with non-small cell lung cancer (NSCLC) have not shown a significant effect in terms of overall survival (OS). Additionally, the effect of PCI among high-risk patients has been scarcely studied. The objective of this randomized phase 2 study was to evaluate the role of PCI in a population of patients at high risk for development of brain metastases (BM). METHODS AND MATERIALS: Eligible patients had histologically confirmed NSCLC without baseline BM, harboring epidermal growth factor receptor mutations, anaplastic lymphoma kinase rearrangements, or elevated carcinoembryonic antigen levels at the time of diagnosis. Participants received systemic therapy according to molecular status, those without progressive disease were then assigned to receive SoC or SoC + PCI (25 Gy in 10 fractions). The primary outcome was cumulative incidence of brain metastases (CBM). The secondary endpoints included progression-free survival and OS. Quality of life and neurocognitive function are discussed in a separate article (Clinicaltrials.gov: NCT01603849). RESULTS: From May 2012 to December 2017, 84 patients were enrolled in the study, with 41 patients allocated to receive PCI and 43 received SoC. Patients allocated to receive PCI had a CBM at 24 months of 7% versus 38% in those allocated to the SoC arm. PCI was associated with a hazard ratio of 0.12 (95% confidence interval, 0.035-0.42) for developing BM. A benefit in OS was also observed (64.5 vs 19.8 months; hazard ratio: 0.41 (95% confidence interval, 0.22-0.78; P =∙007). CONCLUSIONS: Among a selected population at high risk for developing BM, PCI significantly decreased CBM in addition to increasing progression-free survival and OS. To our knowledge, this is the first study to evaluate PCI in epidermal growth factor receptor mutations, anaplastic lymphoma kinase rearrangements, or elevated carcinoembryonic antigen levels in patients with NSCLC, showing a significant improvement in CBM. This relevant information should be of particular importance in the context of patients without access to third-generation targeted agents. Further studies are warranted to ascertain this effect.

Prophylactic Cranial Irradiation in Patients With High-Risk Metastatic Non-Small Cell Lung Cancer: Quality of Life and Neurocognitive Analysis of a Randomized Phase II Study.

PURPOSE: To this date, studies regarding the use of prophylactic cranial irradiation (PCI) versus standard of care (SoC) for patients with non-small cell lung cancer have shown limited benefit in survival outcomes, in addition to the potential effects on quality of life (QoL) and neurocognitive function (NCF). This randomized, phase II study evaluated the role of PCI in QoL and NCF, in a population comprised of subjects at a high risk for development of brain metastases (BM). METHODS AND MATERIALS: Eligible patients had histologically confirmed non-small cell lung cancer without baseline BM, harboring epidermal growth factor receptor mutations, anaplastic lymphoma kinase rearrangements, or elevated carcinoembryonic antigen (CEA) at diagnosis. Participants were assigned to receive SoC or SoC plus PCI (25 Gy in 10 fractions). Primary endpoint was BM at 24 months (BM-24), for which the study was powered. Secondary endpoints included QoL assessed using the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30) and the Lung Cancer module (LC13) and NCF assessed using the Mini Mental State Examination (MMSE). Patients were followed every 3 months for a year for QoL and NCF. RESULTS: From May 2012 to December 2017, 84 patients were enrolled in the study, 41 were allocated to PCI while 43 received SoC. Efficacy outcomes are discussed in a separate article. The global health-QoL scores were similar at 3, 6, 9, and 12 months after randomization between both study arms, with no significant differences when comparing by groups. At 1-year postrandomization, median global health QoL scores were 83 (p25-p75: 75-83) and 83 (p25-p75: 75-83) in the control and experimental arms, respectively. There were no significant changes in terms of the mean differences between subjects in either study arm when analyzing the change between baseline and 12-month scores (16.4 ± 19.9 vs 12.9 ± 14.7; P = .385). Seventeen patients were alive at database lockdown in February 2020, without significant differences in median MMSE (30 [p25-75: 29-30] vs 30 [p25-75: 28-30]) or QLQ-C30 scores (75.0 [p25-75: 50-87.2] vs 67.0 [p25-75: 50.0-100.0]). CONCLUSIONS: Among a selected high-risk population for developing BM, PCI did not significantly decrease QoL or neurocognitive function as assessed using the MMSE. Future studies are warranted to assess this observation, using more varied and sensitive tools available to date.

Outcomes of COVID-19 in patients with primary systemic vasculitis or polymyalgia rheumatica from the COVID-19 Global Rheumatology Alliance physician registry: a retrospective cohort study.

BACKGROUND: Patients with primary systemic vasculitis or polymyalgia rheumatica might be at a high risk for poor COVID-19 outcomes due to the treatments used, the potential organ damage cause by primary systemic vasculitis, and the demographic factors associated with these conditions. We therefore aimed to investigate factors associated with COVID-19 outcomes in patients with primary systemic vasculitis or polymyalgia rheumatica. METHODS: In this retrospective cohort study, adult patients (aged ≥18 years) diagnosed with COVID-19 between March 12, 2020, and April 12, 2021, who had a history of primary systemic vasculitis (antineutrophil cytoplasmic antibody [ANCA]-associated vasculitis, giant cell arteritis, Behçet's syndrome, or other vasculitis) or polymyalgia rheumatica, and were reported to the COVID-19 Global Rheumatology Alliance registry were included. To assess COVID-19 outcomes in patients, we used an ordinal COVID-19 severity scale, defined as: (1) no hospitalisation; (2) hospitalisation without supplemental oxygen; (3) hospitalisation with any supplemental oxygen or ventilation; or (4) death. Multivariable ordinal logistic regression analyses were used to estimate odds ratios (ORs), adjusting for age, sex, time period, number of comorbidities, smoking status, obesity, glucocorticoid use, disease activity, region, and medication category. Analyses were also stratified by type of rheumatic disease. FINDINGS: Of 1202 eligible patients identified in the registry, 733 (61·0%) were women and 469 (39·0%) were men, and their mean age was 63·8 years (SD 17·1). A total of 374 (31·1%) patients had polymyalgia rheumatica, 353 (29·4%) had ANCA-associated vasculitis, 183 (15·2%) had giant cell arteritis, 112 (9·3%) had Behçet's syndrome, and 180 (15·0%) had other vasculitis. Of 1020 (84·9%) patients with outcome data, 512 (50·2%) were not hospitalised, 114 (11·2%) were hospitalised and did not receive supplemental oxygen, 239 (23·4%) were hospitalised and received ventilation or supplemental oxygen, and 155 (15·2%) died. A higher odds of poor COVID-19 outcomes were observed in patients who were older (per each additional decade of life OR 1·44 [95% CI 1·31-1·57]), were male compared with female (1·38 [1·05-1·80]), had more comorbidities (per each additional comorbidity 1·39 [1·23-1·58]), were taking 10 mg/day or more of prednisolone compared with none (2·14 [1·50-3·04]), or had moderate, or high or severe disease activity compared with those who had disease remission or low disease activity (2·12 [1·49-3·02]). Risk factors varied among different disease subtypes. INTERPRETATION: Among patients with primary systemic vasculitis and polymyalgia rheumatica, severe COVID-19 outcomes were associated with variable and largely unmodifiable risk factors, such as age, sex, and number of comorbidities, as well as treatments, including high-dose glucocorticoids. Our results could be used to inform mitigation strategies for patients with these diseases. FUNDING: American College of Rheumatology and the European Alliance of Associations for Rheumatology.

Response rate of patients with baseline brain metastases from recently diagnosed non-small cell lung cancer receiving radiotherapy according to EGFR, ALK and KRAS mutation status.

BACKGROUND: Previous studies have identified that patients with EGFR mutations tend to have better responses to targeted therapy, as well as chemotherapy; however, the effect of genetic alterations in terms of radiotherapy (RT)-related outcomes has not been fully assessed. We studied the impact of common non-small cell lung cancer (NSCLC) genetic alterations (EGFR, ALK and KRAS) in relation to objective response rate (ORR) to RT in patients with brain metastases. METHODS: From 2009-2015, 153 patients with an available genotyping status were treated with whole-brain irradiation (WBI) before receiving systemic therapy. Primary outcome was ORR; secondary outcomes included intracranial progression-free survival (IPFS) and overall survival (OS). RESULTS: Overall, ORR was 47.1%. ORR to RT varied significantly according to molecular status: EGFR (64.5%) ALK (54.5%) KRAS (20%) and WT (35.4%) (P = 0.001). EGFR mutation was the only independently associated factor for response to WBI (RR 3.52 [95% CI 1.6-7.7]; P = 0.002). Median IPFS was 10.8 months [95% CI 8.2-13.5] overall; however, IPFS also varied significantly according to molecular status: EGFR (18.2 months), ALK (18.4 months), KRAS (6.0 months) and WT (8.7 months) (P < 0.0001). OS for EGFR, ALK, KRAS and WT patients was 36.6, 32.2, 15.5 and 22.4 months, respectively (P = 0.014). Intracranial-ORR (HR 0.4 [95% CI 0.2-0.6], P < 0.001) and mutation status (HR 0.7 [95% CI 0.6-0.9], P < 0.042) were independently associated with a higher OS. CONCLUSIONS: RT response varies as per tumor molecular status. The presence of EGFR mutations favors the organ-specific response to RT, and is associated with longer OS in patients with NSCLC and BM. KEY POINTS: This study addressed for the first time the difference in radiotherapy-related outcomes in patients with different genotypes of non-small cell lung cancer (NSCLC) before they received systemic therapy. Results show that response to radiotherapy varies as per tumor molecular status, particularly EGFR-mutated tumors, have a favorable response to radiotherapy, contrary to KRAS-mutated tumors.

Recommendations for detection, prioritization, and treatment of thoracic oncology patients during the COVID-19 pandemic: the THOCOoP cooperative group.

The world currently faces a pandemic due to SARS-CoV-2. Relevant information has emerged regarding the higher risk of poor outcomes in lung cancer patients. As such, lung cancer patients must be prioritized in terms of prevention, detection and treatment. On May 7th, 45 experts in thoracic cancers from 11 different countries were invited to participate. A core panel of experts regarding thoracic oncology care amidst the pandemic gathered virtually, and a total of 60 initial recommendations were drafted based on available evidence, 2 questions were deleted due to conflicting evidence. By May 16th, 44 experts had agreed to participate, and voted on each of the 58 recommendation using a Delphi panel on a live voting event. Consensus was reached regarding the recommendations (>66 % strongly agree/agree) for 56 questions. Strong consensus (>80 % strongly agree/agree) was reached for 44 questions. Patients with lung cancer represent a particularly vulnerable population during this time. Special care must be taken to maintain treatment while avoiding exposure.

Radical aggressive treatment among non-small cell lung cancer patients with malignant pleural effusion without extra-thoracic disease.

Malignant pleural effusion (MPE) is an indicator of advanced disease (stage M1a) in patients with non-small cell lung cancer (NSCLC). Typically, these patients are candidates for palliative treatment. There is a lack of evidence about the radical surgical treatment in carcinomatous pleuritis with massive effusion. Here, we present data from a specific subset of patients with MPE treated with systemic therapy and aggressive surgical therapy. M1a NSCLC adenocarcinoma patients with MPE and without extra-thoracic disease were included. After receiving systemic therapy, all patients underwent surgical treatment, which included pneumonectomy or lobectomy, plus mediastinal dissection. Following surgery, patients received radiotherapy to thoracic wall and mediastinum. A total of six patients were analyzed. All patients had an Eastern Cooperative Oncology Group (ECOG) performance status ≤1, two patients harbored EGFR mutation and were treated with tyrosine kinase inhibitors (TKIs), the other four patients were treated with pemetrexed and platin as first-line treatment. Following systemic therapy, two patients had a pneumonectomy, four patients had a lobectomy plus pleurectomy performed. All patients continued with maintenance systemic therapy, and achieved complete responses, according to RECIST 1.1 criteria. The media progression-free survival (PFS) time was 15.9 months (95% CI: 15.6-55.5 months). At the last follow-up, all patients were still alive, with 4 of them without signs of macroscopic tumoral activity. The median overall survival (OS) was not reached. NSCLC patients with MPE without extra-thoracic disease could benefit from an aggressive surgical approach following standard of care systemic therapy. However, considering the low sample size of this study and the relatively low incidence of MPE without extra-thoracic disease, further prospective multi-center studies are necessary to evaluate aggressive surgery as a therapeutic option.

Radical consolidative treatment provides a clinical benefit and long-term survival in patients with synchronous oligometastatic non-small cell lung cancer: A phase II study.

OBJECTIVES: Evidence is rapidly accumulating for the use of radical consolidative treatment (RCT) for patients with oligometastatic non-small cell lung cancer (NSCLC). Nonetheless, published studies have several limitations, including a selection of patients whose favorable characteristics might dictate therapeutic success, as well as scarce prospective data regarding overall survival (OS). The objective of this study was to determine whether RCT increases OS in patients with oligometastatic NSCLC. MATERIALS AND METHODS: In this prospective, single-arm phase II study, we sought to evaluate the efficacy of RCT in patients with oligometastatic NSCLC in terms of OS. Patients with pathologically confirmed stage IV NSCLC who presented ≤5 synchronous, any-site metastases (including central nervous system [CNS] metastases), as assessed by PET-CT, were included. All patients received four initial cycles of systemic treatment. Following, those with stable disease/partial response received RCT to the primary site and metastases. The response to RCT was evaluated with PET-CT. The primary end-point was OS. Secondary end-points included progression-free survival (PFS) and best response by PET-CT. The study is registered in clinicaltrials.gov (NCT02805530). RESULTS: Thirty-seven patients were included in the analysis. The mean age was 55.8 years (range: 33-75 years). At diagnosis, 43.2% of patients presented with CNS metastases. Following RCT, 19 (51.4%) patients achieved a complete-response (CR) by PET-CT, while 18 (48.6%) had a non-complete response (NON-CR). The median OS was nonreached (NR) and was positively affected by CR on PET-CT (NR vs. 27.4 [95% CI: 16.4-38.3]; p = 0.011). The median PFS was 23.5 months (95% CI: 13.6-33.3) and was positively affected by CR on PET-CT (NR vs. 14.3 [95% CI: 11.7-16.9]; p < 0.001; HR: 0.19 [0.07-0.52]; p=0.001). CONCLUSION: Patients with oligometastatic NSCLC who undergo RCT have a high response rate and favorable OS. Patients with a CR by PET-CT have significantly longer OS, rendering this an important potential prognostic marker.

Características epidemiológicas y desenlaces de la infección por SARS-CoV-2 en pacientes con patologías reumáticas: Primer reporte del registro argentino SAR-COVID / Epidemiological characteristics and outcomes of SARS-CoV-2 infection in patients with rheumatic diseases: First report from the Argentine SAR-COVID registry

Con el fin de evaluar el impacto de la infección por SARS-CoV-2 en pacientes con enfermedades reumáticas, la Sociedad Argentina de Reumatología desarrolló el Registro Nacional de Pacientes con Enfermedades Reumáticas y COVID-19 (SAR-COVID). El objetivo del presente trabajo fue evaluar las características sociodemográficas y clínicas de los pacientes con enfermedades reumáticas e infección por SARS-CoV-2 incluidos en el registro SAR-COVID y describir las complicaciones y desenlaces de la COVID-19 en esta población. Material y métodos: SAR-COVID es un registro nacional, multicéntrico y observacional, en el cual se incluyen de manera consecutiva pacientes ≥18 años de edad, con diagnóstico de alguna enfermedad reumática que hayan cursado infección por SARS-CoV-2. Se consignan datos sociodemográficos, comorbilidades, enfermedad reumática y su tratamiento, características clínicas, laboratorio, complicaciones y tratamientos de la infección por SARS-CoV-2. Resultados: Se incluyeron 525 pacientes, con una edad media de 51.3 años (DE 15.2). Las enfermedades reumatológicas más frecuentes fueron artritis reumatoidea (40.4%), lupus eritematoso sistémico (14.9%) y espondiloartritis (8.2%). El 72.9% recibía tratamiento inmunosupresor o inmunomodulador al momento del inicio de la infección y 36.9% glucocorticoides. En la mayoría de los casos, el diagnóstico de infección por SARS-CoV-2 se llevó a cabo mediante RT-PCR (95%), 39.4% en la consulta externa, 32.2% en el departamento de urgencias, y 14.7% durante la hospitalización. La mayoría de los pacientes presentaron síntomas, siendo los más frecuentes fiebre (56.2%), tos (46.7%) y cefalea (39.2%). Durante la infección, 35.1% requirieron hospitalización y 11.6% en unidad de cuidados intensivos. El 75.1% se recuperó completamente, 8.4% presentó secuelas y 6.9% murieron a causa de COVID-19. Conclusión: En este primer reporte del registro SAR-COVID encontramos una amplia distribución de enfermedades reumáticas. La mayoría de los pacientes tuvieron una buena evolución de la infección, sin embargo un 7% falleció como consecuencia de la misma, datos comparables a los reportados por otros registros latinoamericanos con poblaciones similares.

In order to assess the impact of SARS-CoV-2 infection in patients with rheumatic diseases, the Argentine Society of Rheumatology has developed the National Registry of Patients with Rheumatic Diseases and COVID-19 (SAR-COVID). The aim of this study was to evaluate the sociodemographic and clinical characteristics of patients with rheumatic diseases and SARS-CoV-2 infection included in the SAR-COVID registry and to describe the complications and outcomes of COVID-19 in this population. Methods: SAR-COVID is a national, multicenter and observational registry, in which patients ≥18 years of age, with a diagnosis of a rheumatic disease who had SARS-CoV-2 infection are consecutively included. Sociodemographic data, comorbidities, underlying rheumatic disease and treatment, clinical characteristics, complications, laboratory and treatment of the SARS-CoV-2 infection were recorded. Results: A total of 525 patients were included, with a mean age of 51.3 years (SD 15.2). The most frequent rheumatic diseases were rheumatoid arthritis (40.4%), systemic lupus erythematous (14.9%) and spondyloarthritis (8.2%). At the time of the infection, 72.9% were receiving immunosuppressive or immunomodulatory treatment and 36.9% glucocorticoids. Most of the patients were diagnosed using RT-PCR (95%), at outpatient consultation (39.4%), at the emergency room (32.2%) or during hospitalization (14.7%). Symptoms were present in 96% of the patients, the most frequent being fever (56.2%), cough (46.7%) and headache (39.2%). During infection, 35.1% were hospitalized, 11.6% were admitted to the ICU and 6.9% died due to COVID-19. Most of them (75.1%) recovered completely. Conclusions: In this first report of the SAR-COVID registry we found a wide distribution of rheumatic diseases. Most of the patients had a good evolution of the infection, however 7% died as a result of it, comparable to other Latin American registries with similar populations.

Prognostic factors in patients with minor salivary gland carcinoma of the oral cavity and oropharynx.

BACKGROUND: This study was performed to define prognostic factors and management of minor salivary gland carcinoma of the oral cavity and oropharynx . METHODS: Retrospective analyses of patients with salivary gland carcinoma of the oral cavity or oropharynx, treated in 1989 to 2006. Statistics included univariate analyses to identify prognostic factors associated with disease-free survival (DFS) and disease-specific survival. A multivariate analysis model was constructed by the Cox method. RESULTS: Seventy-seven patients constituted our cohort. Significant prognostic factors regarding DFS and disease-specific survival in univariate analyses comprised tumor size, surgical margins, grade, lymph node status, and Karnofsky status and T classification. A multivariate model identified tumor size, grade, surgical margins, and lymph node status significant regarding DFS. CONCLUSIONS: Tumor size, grade, surgical margins, and lymph node status could be used for a rational design of treatment strategies in these rare tumors.
