RESUMO

INTRODUCCIÓN: El síndrome de tormenta de citoquinas (STC) es una complicación muy grave de los pacientes con infección por SARS-CoV-2. El tratamiento y la evolución no están bien definidos. Nuestro objetivo es describir sus características clínicas, los tratamientos empleados y su evolución clínica. PACIENTES Y MÉTODO: Estudio retrospectivo observacional de pacientes consecutivos ingresados en el período comprendido entre el 23 de marzo y el 12 de abril de 2020 con infección por SARS-CoV-2 confirmada, con neumonía por estudio radiológico o tomografía de tórax, que cumplían criterios de STC y que recibieron tratamiento. Clasificamos a los pacientes en los que recibieron solo pulsos de glucocorticoides (GC), o pulsos de GC y tocilizumab. Determinamos niveles séricos de ferritina, PCR y dímeros-D. La variable final fue la supervivencia. RESULTADOS: Veintiún pacientes con una edad de 83 años (80-88 años). La ferritina media fue de 1.056 microg/L (317-3.553), la PCR de 115,8mg/dL (22-306) y los dímeros-D de 2,9mg/L (0,45-17,5). Todos los pacientes recibieron pulsos de GC y en 2 casos simultáneamente tocilizumab. El tiempo medio de seguimiento fue de 13,7 días (8-21). La mortalidad global fue del 38,1% (8/21pacientes). Los 2 pacientes que recibieron tocilizumab fallecieron. Los fallecidos presentaron niveles significativamente más elevados de ferritina (1.254 vs. 925microg/L; p = 0,045) y PCR (197,6 vs. 76mg/dL; p = 0,007). Al final del seguimiento se observó una disminución en los parámetros bioquímicos con ferritina de 727microg/L, PCR de 27mg/dl y dímeros-D de 1,18mg/L. En 13/21 pacientes (61,9%) el STC se controló sin necesidad de añadir otros tratamientos. CONCLUSIONES: La mortalidad del STC por SARS-CoV-2 es alta a pesar del tratamiento. Una mayor respuesta inflamatoria se asoció con una mayor mortalidad. Aunque parece que el uso precoz de pulsos de GC puede controlarlo, pudiendo disminuir la necesidad de uso de otros tratamientos, con el diseño del estudio y sus limitaciones, no se puede establecer esta conclusión


INTRODUCTION: Cytokine storm syndrome (CTS) is a serious complication of patients with SARS-CoV-2 infection. Treatment and evolution in octogenarians are not well defiREVned. Our objective is to describe its clinical characteristics, the treatments and its clinical evolution. PATIENTS AND METHOD: Retrospective observational study of consecutive patients admitted in the period between March 23 and April 12, 2020 with confirmed SARS-CoV-2 infection, with pneumonia by radiological study or chest tomography, whith STC criteria and who received treatment. We classified patients as those who received only glucocorticoid (GC) pulses, or GC and tocilizumab pulses. We determined serum levels of ferritin, CRP and D-dimers. The final variable was survival. RESULTS: 21 patients, (80-88 years). The mean ferritin was 1056 microg/L (317-3,553), CRP 115.8mg/dL (22-306) and D-dimers 2.9m/L (0.45-17.5). All patients received GC pulses and in 2 cases simultaneously tocilizumab. The mean follow-up time was 13.7 days (8-21). The overall mortality was 38.1% (8/21 patients). The 2 patients who received tocilizumab died. The deceased had significantly higher levels of ferritin (1,254 vs. 925microg/L; P=.045) and CRP (197.6 vs. 76mg / dL; P=.007). At the end of the follow-up, a decrease in the biochemical parameters was observed with ferritin of 727microg/L, CRP of 27mg/dl and D-dimers of 1.18mg/L. In 13/21 patients (61.9%), the CTS was controlled without the need to add other treatments. CONCLUSIONS: STC mortality from SARS-CoV-2 is high despite treatment. A greater inflammatory response was associated with a higher mortality. Although it seems that the early use of GC pulses could control it, and the use of other treatments such as tocilizumab shouldo be, with the study design and its limitations, this conclusion cannot be stablished

RESUMO

Objectives: To evaluate the role of short-term low-dose glucocorticoids in mild COVID-19 patients. Methods: We conducted a retrospective, cross-sectional, single-center study in Kunming, China. A total of 33 mild COVID-19 cases were divided into two treatment groups (with and without glucocorticoids, methylprednisolone, were used in this setting), and the absolute value of peripheral blood lymphocyte count; CD3+, CD4+, and CD8+ T cell counts; and the time to achieve negative transformation of a nucleic acid pharyngeal swab were recorded. Peripheral blood lymphocyte and T cell counts were compared between the treatment group and 25 healthy individuals. At the point of time when there was a 50% accumulation conversion rate (positive to negative nucleic acid on pharyngeal swab), and the nucleic acid turned negative in half of the patients in two groups, the peripheral blood lymphocyte and T cell counts were compared between treatment groups. Results: The mean cumulative time for the 50% negative conversion rate of the nucleic acid in the pharyngeal swab was 17.7 ± 5.1 days and 13.9 ± 5.4 days in the glucocorticoid group and the nonglucocorticoid group, respectively. The absolute peripheral blood lymphocyte count and the T cell subset count in the glucocorticoid group were lower than those in the nonglucocorticoid group. When the nucleic acid turned negative in half of the patients, the absolute value of peripheral blood lymphocyte count and CD4+ T cells of the glucocorticoid group and the nonglucocorticoid group was not significantly different; the CD3+ and CD8+ T cells in the glucocorticoid group were lower than those in the nonglucocorticoid group. The absolute peripheral blood lymphocyte count, CD3+ T cells, and CD4+ T cells in the glucocorticoid group were lower than those of the healthy group during the whole disease period, and CD8+ T cells returned to normal at 19-21 days of the disease period. There was no significant difference between the nonglucocorticoid group and the healthy group for absolute peripheral blood lymphocyte and CD8+ T cells; moreover, CD3+ T cells and CD4+ T cells were lower in the nonglucocorticoid group than those in the healthy group from the day of admission to the 18th day and returned to normal at the period of 19-21 days. The absolute peripheral lymphocyte count (P = 0.048, effect size d = 0.727) and T cell subset count (CD3: P = 0.042, effect size d = 0.655; CD4: P < 0.01, effect size d = 0.599; and CD8: P = 0.034, effect size d = 0.550) in the nonglucocorticoid group were higher than those in the glucocorticoid group, and the difference between the groups was statistically significant. Conclusions: This study found that the use of short-term, low-dose glucocorticoids does not negatively influence the clinical outcome, without affecting the final clearance of viral nucleic acid in mild COVID-19 patients.

RESUMO

BACKGROUND: Manipulation under anaesthesia and arthroscopic capsular release are costly and invasive treatments for frozen shoulder, but their effectiveness remains uncertain. We compared these two surgical interventions with early structured physiotherapy plus steroid injection. METHODS: In this multicentre, pragmatic, three-arm, superiority randomised trial, patients referred to secondary care for treatment of primary frozen shoulder were recruited from 35 hospital sites in the UK. Participants were adults (≥18 years) with unilateral frozen shoulder, characterised by restriction of passive external rotation (≥50%) in the affected shoulder. Participants were randomly assigned (2:2:1) to receive manipulation under anaesthesia, arthroscopic capsular release, or early structured physiotherapy. In manipulation under anaesthesia, the surgeon manipulated the affected shoulder to stretch and tear the tight capsule while the participant was under general anaesthesia, supplemented by a steroid injection. Arthroscopic capsular release, also done under general anaesthesia, involved surgically dividing the contracted anterior capsule in the rotator interval, followed by manipulation, with optional steroid injection. Both forms of surgery were followed by postprocedural physiotherapy. Early structured physiotherapy involved mobilisation techniques and a graduated home exercise programme supplemented by a steroid injection. Both early structured physiotherapy and postprocedural physiotherapy involved 12 sessions during up to 12 weeks. The primary outcome was the Oxford Shoulder Score (OSS; 0-48) at 12 months after randomisation, analysed by initial randomisation group. We sought a target difference of 5 OSS points between physiotherapy and either form of surgery, or 4 points between manipulation and capsular release. The trial registration is ISRCTN48804508. FINDINGS: Between April 1, 2015, and Dec 31, 2017, we screened 914 patients, of whom 503 (55%) were randomly assigned. At 12 months, OSS data were available for 189 (94%) of 201 participants assigned to manipulation (mean estimate 38·3 points, 95% CI 36·9 to 39·7), 191 (94%) of 203 participants assigned to capsular release (40·3 points, 38·9 to 41·7), and 93 (94%) of 99 participants assigned to physiotherapy (37·2 points, 35·3 to 39·2). The mean group differences were 2·01 points (0·10 to 3·91) between the capsular release and manipulation groups, 3·06 points (0·71 to 5·41) between capsular release and physiotherapy, and 1·05 points (-1·28 to 3·39) between manipulation and physiotherapy. Eight serious adverse events were reported with capsular release and two with manipulation. At a willingness-to-pay threshold of £20 000 per quality-adjusted life-year, manipulation under anaesthesia had the highest probability of being cost-effective (0·8632, compared with 0·1366 for physiotherapy and 0·0002 for capsular release). INTERPRETATION: All mean differences on the assessment of shoulder pain and function (OSS) at the primary endpoint of 12 months were less than the target differences. Therefore, none of the three interventions were clinically superior. Arthoscopic capsular release carried higher risks, and manipulation under anaesthesia was the most cost-effective.

RESUMO

INTRODUCTION: Pneumonia is one of the most important characteristics of coronavirus disease 2019 (COVID-19) and imaging findings of COVID-19 pneumonia are diverse and change over disease course. However, the detailed clinical course of organizing pneumonia (OP) caused by COVID-19 has not been clarified. PATIENT CONCERNS: A 60-year-old man and a 61-year-old woman diagnosed with mild COVID-19 were admitted to our hospital. Their respiratory symptoms were deteriorating even after initiating treatment with antiviral drugs. DIAGNOSIS: Chest X-rays and computed tomography scan showed a rapid progression of linear consolidation with reversed halo sign, distributed in subpleural and peri-bronchial regions. They also presented with pulmonary fibrosis findings, including traction bronchiectasis and marked lung volume reduction. They were diagnosed with rapidly progressing OP. INTERVENTIONS: They were treated with systemic corticosteroids. OUTCOMES: The patients' imaging findings and respiratory conditions improved rapidly without any adverse effects. CONCLUSION: Physicians should carefully monitor patients with COVID-19, as they can develop rapidly progressive and fibrotic OP, which respond to corticosteroids.

RESUMO

RATIONALE: The clinical manifestations of the SARS-CoV-2 infection are mainly respiratory but the virus can cause a variety of symptoms. Dermatological findings are less well-characterized. Data is scarce on their timing, type and correlation with the immune response. PATIENT CONCERNS: We present the case of SARS-CoV-2 infection in a previously healthy woman who presented with respiratory symptoms and developed anosmia, diarrhea, and an erythematous maculo-papular rash on day 15 from symptom onset. DIAGNOSIS: The nasopharyngeal swab tested by real time PCR for COVID-19 was positive. We interpreted this as a viral exanthema likely caused by an immune response to SARS-CoV-2 nucleotides. INTERVENTIONS: She was treated with Hydroxychloroquine, Azithromycin and Lopinavir/Ritonavir, and the rash with topical corticosteroids. OUTCOMES: All symptoms resolved except for anosmia which persisted for 6 weeks. At the 4- and 6-weeks follow-up the IgG titers for SARS-CoV-2 were high. LESSONS: We must consider that SARS-CoV-2 has a multi-organ tropism. In our case, the SARS-CoV-2 infection had lung, nasopharyngeal, neurological, digestive, and skin manifestations. Identifying the different manifestations is useful for understanding the extent of SARS-CoV-2 infection. We not only present a rare manifestation but also suggest that cutaneous manifestations may correlate with immunity.

RESUMO

RATIONALE: We report a case of central retinal artery occlusion (CRAO) accompanied by choroidal folds in a patient positive for myeloperoxidase (MPO)-antineutrophil cytoplasmic antibody (ANCA). PATIENT CONCERNS: The study involved a 67-year-old female patient who presented at the Department of Ophthalmology, Osaka Medical College, Takatsuki-City, Osaka, Japan on October 24, 2016 after becoming aware of a sudden decrease of visual acuity (VA) in her right eye. Other than suffering with scleritis 6-months previous, there was no obvious past history. DIAGNOSIS: Upon examination, the VA in her right eye was hand motion, and the anterior segment of that eye showed thinning of the superior sclera. Macular edema in the inner retina and cherry red spots were observed in the ocular fundus, and optical coherence tomography (OCT) findings showed hyperreflectivity of the inner retina and choroidal folds. Fluorescein angiography (FA) examination of the fundus showed scattered areas of no retinal perfusion, and indocyanine green angiography (IA) findings of the fundus indicated a possible choroidal circulatory disturbance in her right eye. Blood test findings revealed the patient to be positive for MPO-ANCA. Based on the above findings, the patient was diagnosed with CRAO and choroidal circulatory disturbance due to ANCA-associated vasculitis. INTERVENTIONS: For treatment, steroid semi-pulse therapy was initiated. OUTCOMES: Post treatment initiation, the fundus features and choroidal folds gradually improved, and her VA slightly improved to 0.08. LESSONS: Based on the FA, IA, and OCT findings, the present case was considered to have CRAO accompanied by choroidal circulatory disturbance due to ANCA-associated vasculitis, a rare disease that may be complicated by choroidal circulatory disturbances.

RESUMO

INTRODUCTION: Hemophagocytic lymphohistiocytosis (HLH) is a condition characterized by a hyperinflammatory state and persistent macrophage activation, resulting in reactive phagocytosis of the hematopoietic elements. In children, it is usually a hereditary disorder, while in adults it is usually acquired secondary to viral infections, collagenoses, or tumors. Although accounting for 10% of hematologic malignancies, HLH is rarely associated with multiple myeloma (MM) and other plasmacytic dyscrasias. PATIENT CONCERNS: A 64-year-old Brazilian man seeked medical care with a 3-month history of intermittent fever, weight loss, night sweats, and progressive anemic symptoms. DIAGNOSIS: Total blood count showed severe bicytopenia (normocytic-normochromic anemia and thrombocytopenia), biochemical exams showed elevation of creatinine, as well as monoclonal peak in serum protein electrophoresis, high IgA dosage, and serum immunofixation with IgA kappa paraprotein. Bone marrow biopsy showed 30% of monoclonal and phenotypically anomalous plasmocytes, confirming the diagnosis of MM. Diagnosis of HLH was established by the presence of clinical and laboratory criteria: fever, splenomegaly, cytopenias, hypofibrinogenemia, hyperferritinemia, elevation of triglycerides, and several figures of erythrophagocytosis in bone marrow aspirate. INTERVENTIONS: The patient experienced pulse therapy with methylprednisolone for hemophagocytic lymphohistiocytosis, followed by initial therapy for multiple myeloma with cyclophosphamide and dexamethasone. OUTCOMES: Once the diagnosis of MM and secondary hemophagocytic syndrome was established, the patient had a rapid clinical deterioration despite the established therapeutic measures, evolving with cardiovascular failure, acute liver failure, acute disseminated intravascular coagulation, worsening renal dysfunction requiring dialysis support, respiratory dysfunction, and lowering of consciousness, characterizing rapid multiple organ dysfunction, ultimately leading to the death of the patient. INNOVATION: Here, we aimed to describe the sixth reported case of HLH associated with MM, according to cases cataloged in the PubMed database, and the first case evaluated by 18-fluordeoxyglucose positron emission tomography (18-FDG-PETCT). CONCLUSION: Our case report seeks to provide support for a better clinical and laboratory characterization of this rare paraneoplastic entity associated with MM, and aims to call the attention of hematologists and intensivists to this condition that falls within the scope of the differential diagnosis of rapid onset multiple organ failure in patients with plasmacytic neoplasms.

RESUMO

RATIONALE: The Goodpasture syndrome is an extremely rare disease, with renal and pulmonary manifestations, and is mediated by anti-glomerular basement membrane (anti-GBM) antibodies. Renal pathological changes are mainly characterized by glomerular crescent formation and linear immunofluorescent staining for immunoglobulin G on the GBM. There are few reports on the atypical course of the syndrome involving serum-negative anti-GBM antibodies. Therefore, we present a case of Goodpasture syndrome that presented with nephrotic-range proteinuria and was seronegative for anti-GBM antibodies. PATIENT CONCERNS: A 38-year-old Chinese man presented with a lung lesion that was discovered by physical examination a month prior to presentation. The chief concern was occasional hemoptysis without fever, cough, chest pain, and edema. DIAGNOSES: Laboratory testing revealed that the urinary protein level and urine erythrocyte count were 7.4 g/24 hours and 144/high-power field (HPF), respectively. Serological testing for anti-GBM antibodies was negative. Chest computed tomography revealed multiple exudative lesions in both lungs, indicating alveolar infiltration and hemorrhage. Electronic bronchoscopy and pathological examination of the alveolar lavage fluid indicated no abnormalities. However, kidney biopsy suggested cellular crescent formation and segmental necrosis of the globuli, with linear IgG and complement C3 deposition on the GBM. These findings were consistent with the diagnosis of anti-GBM antibody nephritis. INTERVENTIONS: The patient underwent 7 sessions of double filtration plasmapheresis. He was also administered with intravenous methylprednisolone and cyclophosphamide. After renal function stabilization, he was discharged under an immunosuppressive regimen comprising of glucocorticoids and cyclophosphamides. OUTCOMES: Three months later, follow-up examination revealed that the 24-hour urine protein had increased to 13 g. Furthermore, the urine erythrocyte count was 243/HPF. After a 6-month follow-up, the patient achieved partial remission, with a proteinuria level of 3.9 g/24 hours and a urine erythrocyte count of 187/HPF. LESSONS: This extremely rare case of Goodpasture syndrome manifested with seronegativity for anti-GBM antibodies and nephrotic-range proteinuria. Our findings emphasize the importance of renal biopsy for the clinical diagnosis of atypical cases. Furthermore, because renal involvement achieved only partial remission despite therapy, early detection and active treatment of the Goodpasture syndrome is necessary to improve the prognosis of patients.

RESUMO

INTRODUCCIÓN: el síndrome de liberación de citoquinas (SLC) es una complicación grave de los pacientes COVID-19. La base del tratamiento es tocilizumab. El uso de glucocorticoides (GC) es controvertidos. En otros SLC muy parecidas, como son el síndrome de activación macrofágica (SAM) y el síndrome hemofagocítico (SHF) los corticoides fundamentales. Nuestro objetivo es evaluar la eficacia de los GC en el SLC por COVID-19. PACIENTES: incluimos 92 pacientes con SLC por COVID-19 que recibieron GC, GC y tocilizumab y sólo tocilizumab. Determinamos marcadores de SLC. Evaluamos mortalidad, intubación y una variable combinada. RESULTADOS: en todos los casos los porcentajes de eventos fueron menores en el grupo de pacientes en los que se administraron GC. Las razones de riesgo delas variables finales de los grupos con GC frente al grupo en el que se administró sólo tocilizumab fue menor conforme se consideraron los GC, con significación estadística para la supervivencia. DISCUSIÓN: el uso precoz de pulsos de GC puede controlar el SLC, con un menor requerimiento de uso de tocilizumab y una disminución de eventos como la intubación y muerte


INTRODUCTION: cytokine stormsyndrome (CSS) is a serious complication of COVID-19 patients. Treatment is tocilizumab. The use of glucocorticoids (GC) is controversial. In other very similar CSS, such as macrophage activation syndrome (MAS) and hemophagocytic syndrome (HFS), the main treatment are corticosteroids. Our objective is to evaluate the efficacy of GC in the CSSby COVID-19. PATIENTS: we included 92 patients with CSS associated to COVID-19 who received GC, GC, and tocilizumab and only tocilizumab. We determine CSS markers. We evaluated mortality, intubation, and a combined variable. RESULTS: in all cases the percentages of events were lower in the group of patients with GC was administered. The hazardratio of the final variables with GC versus the group in which only tocilizumab was administered was lower as CGs were considered, with statistical significance for survival. DISCUSSION: the early use of GC pulses couldcontrol SLC, with a lower requirement to use tocilizumab and a decrease in events such as intubation and death

INTERVENTION AND COMPARATOR: Eligible patients will be randomized to receive standard ICU patient care (group 1) or standard ICU patient care plus high dose dexamethasone (group 2). Group 1: dexamethasone up to 6 mg/24 hours for up to 10 days + ventilatory, hemodynamic, nutritional, and antimicrobial support according to international guidelines. Group 2: dexamethasone 16 mg/24 hours for 5 days followed by dexamethasone 8 mg/24 hours for 5 days + ventilatory, hemodynamic, nutritional, and antimicrobial support according to international guidelines. MAIN OUTCOME: The main result is ventilator-free days at 28 days (Days without ventilator support in the first 28 days following randomization). Secondary outcomes are 28-days and 90-days mortality, frequency of nosocomial infections in the first 28 days after randomization, Sequential Organ Failure Assessment (SOFA) score variation and prone position in the first 10-days, viral shedding 28-days after randomization, and delirium and muscle weakness at ICU discharge. RANDOMISATION: Treatment will be assigned according to site stratified randomization by permuted random blocks sequence 1:1 generated with a table in R language concealed in a randomization tool in REDCap (Research Electronic Data CAPture) platform. BLINDING (MASKING): This is an open trial, so no masking of treatment assignment will be used. NUMBERS TO BE RANDOMISED (SAMPLE SIZE): Assuming a 3 days difference in ventilator-free days between treatment groups, with a mean of 9 days, and a standard deviation of 9 days; the necessary sample size would be 284 subjects (142 per group), with a power of 80% and a two-tailed alpha error of 0.05. TRIAL STATUS: The protocol with code 1264, version 3.0 on date: May 13, 2020 is approved by the local Ethics Committee. The trial is in the recruitment phase. Recruitment began May 22, 2020 and is anticipated to be complete by the end of December 2021. TRIAL REGISTRATION: The trial was registered under the title "Dexamethasone for COVID-19 Related ARDS: a Multicenter, Randomized Clinical Trial" with ClinicalTrials number NCT04395105, https://clinicaltrials.gov/ct2/show/NCT04395105 , registered on 20 May 2020.

RESUMO

BACKGROUND The effect of corticosteroids in the management of patients with coronavirus disease 2019 (COVID-19) is unclear. CASE REPORT A 67-year-old man who tested positive for COVID-19 by reverse-transcription PCR (RT-PCR) analysis was admitted to our hospital. On admission, he had no dyspnea and his oxygen saturation (SpO2) level was normal. Chest imaging revealed ground-glass opacities (GGO) distributed in both lung fields. Four days after admission, bilateral lung shadows worsened, with a slight reduction in SpO2 levels. Short-term corticosteroid therapy was initiated, and SpO2 and radiographic findings promptly improved without use of antiviral agents. CONCLUSIONS More data are required to ascertain the role of corticosteroids in the management of COVID-19 pneumonia.

RESUMO

The efficacy of glucocorticoids in COVID-19 is unclear. This study was designed to determine whether systemic glucocorticoid treatment in COVID-19 patients is associated with reduced mortality or mechanical ventilation. This observational study included 1,806 hospitalized COVID-19 patients; 140 were treated with glucocorticoids within 48 hours of admission. Early use of glucocorticoids was not associated with mortality or mechanical ventilation. However, glucocorticoid treatment of patients with initial C-reactive protein (CRP) ≥20 mg/dL was associated with significantly reduced risk of mortality or mechanical ventilation (odds ratio, 0.23; 95% CI, 0.08-0.70), while glucocorticoid treatment of patients with CRP <10 mg/dL was associated with significantly increased risk of mortality or mechanical ventilation (OR, 2.64; 95% CI, 1.39-5.03). Whether glucocorticoid treatment is associated with changes in mortality or mechanical ventilation in patients with high or low CRP needs study in prospective, randomized clinical trials.

RESUMO

BACKGROUND: It is commonly believed that mTOR inhibitors (mTORi) should not be used in high-immunological risk kidney transplant recipients due to a perceived increased risk of rejection. However, almost all trials that examined the association of optimal-dose mTORi with calcineurin inhibitor (CNI) have excluded hypersensitized recipients from enrollment. METHODS: To shed light on this issue, we examined 71 consecutive patients with a baseline calculated panel reactive antibody (cPRA) ≥50% that underwent kidney transplantation from June 2013 to December 2016 in our unit. Immunosuppression was based on CNI (tacrolimus), steroids and alternatively mycophenolic acid (MPA; n = 38), or mTORi (either everolimus or sirolimus, n = 33, target trough levels 3-8 ng/mL). RESULTS: Demographic and immunological risk profiles were similar, and almost 90% of patients in both groups received induction with lymphocyte-depleting agents. Cox-regression analysis of rejection-free survival revealed better results for mTORi versus MPA in terms of biopsy-proven acute rejection (hazard ratio [confidence interval], 0.32 [0.11-0.90], P = 0.031 at univariable analysis and 0.34 [0.11-0.95], P = 0.040 at multivariable analysis). There were no differences in 1-year renal function, Banff chronicity score at 3- and 12-month protocol biopsy and development of de novo donor-specific antibodies. Tacrolimus trough levels along the first year were not different between groups (12-mo levels were 8.72 ± 2.93 and 7.85 ± 3.07 ng/mL for MPA and mTORi group respectively, P = 0.277). CONCLUSIONS: This single-center retrospective cohort analysis suggests that in hypersensitized kidney transplant recipients receiving tacrolimus-based immunosuppressive therapy similar clinical outcomes may be obtained using mTOR inhibitors compared to mycophenolate.

RESUMO

BACKGROUND AND OBJECTIVES: Historically, autosomal recessive 5q-linked spinal muscular atrophy (SMA) has been the leading inherited cause of infant death. SMA is caused by the absence of the SMN1 gene, and SMN1 gene replacement therapy, onasemnogene abeparvovec-xioi, was Food and Drug Administration approved in May 2019. Approval included all children with SMA age <2 years without end-stage weakness. However, gene transfer with onasemnogene abeparvovec-xioi has been only studied in children age ≤8 months. METHODS: In this article, we report key safety and early outcome data from the first 21 children (age 1-23 months) treated in the state of Ohio. RESULTS: In children ≤6 months, gene transfer was well tolerated. In this young group, serum transaminase (aspartate aminotransferase and alanine aminotransferase) elevations were modest and not associated with γ glutamyl transpeptidase elevations. Initial prednisolone administration matched that given in the clinical trials. In older children, elevations in aspartate aminotransferase, alanine aminotransferase and γ glutamyl transpeptidase were more common and required a higher dose of prednisolone, but all were without clinical symptoms. Nineteen of 21 (90%) children experienced an asymptomatic drop in platelets in the first week after treatment that recovered without intervention. Of the 19 children with repeated outcome assessments, 11% (n = 2) experienced stabilization and 89% (n = 17) experienced improvement in motor function. CONCLUSIONS: In this population, with thorough screening and careful post-gene transfer management, replacement therapy with onasemnogene abeparvovec-xioi is safe and shows promise for early efficacy.

RESUMO

BACKGROUND: Evidence-based practices in medicine are linked with a higher quality of care and lower health care cost. For trigger finger, identifying patient factors associated with nonadherence to evidence-based practices will aid physicians in treatment decisions. The objectives were to (1) determine patient factors associated with treatment nonadherence, (2) examine the success rates of steroid injections, and (3) evaluate the economic consequences of nonadherence to treatment recommendations. METHODS: The authors used data from the Clinformatics DataMart database from 2010 to 2017 to conduct a population-based analysis of patients with single-digit trigger finger. The authors calculated rates of steroid injection success and examined associations between injection success and patient factors using chi-square tests. In addition, the authors analyzed differences in the cost to the insurer, the cost to the patient, and total cost. RESULTS: A total of 29,722 patients were included in this analysis. Injection success rates were similar for diabetic (72 percent) and nondiabetic patients (73 percent), women (73 percent), and men (73 percent). Nonetheless, diabetics (OR, 1.4; 95 percent CI, 1.4 to 1.5; p < 0.001) and women (OR, 1.2; 95 percent CI, 1.1 to 1.2; p < 0.001) were significantly more likely to receive nonadherent treatment. In total, $23 million (U.S. dollars) were spent on nonadherent trigger finger care. CONCLUSIONS: Diabetics and women have increased odds of having surgery without a prior steroid injection, despite similar success rates of steroid injections compared to nondiabetics and men. Because performing surgical release before any steroid injections may represent a higher cost treatment option, providers should provide steroid injections before surgery for all patients regardless of diabetes status or sex to minimize overtreatment. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

RESUMO

To describe the epidemiological and clinical characteristics of patients with Corona Virus Disease 2019 (COVID-19) in Beijing. To analyze the application of corticosteroids in patients with severe pneumonia. We collected information on demographic characteristics, exposure history, clinical characteristics, corticosteroids use, and outcomes of the 65 confirmed cases of COVID-19 at Fifth Medical Center of PLA General Hospital from Jan 20 to Feb 23, 2020. The final follow-up date observed was April 15th, 2020. The number of patients with mild, general, severe, and critical type were 10 (15.38%), 32 (49.23%), 8 (12.31%), and 15 (23.08%), respectively. The median incubation period was 6 days. Notable outliers were 1 patient at 16 days and 1 patient at 21 days. In lymphocyte subgroup analysis, decreases in total, T, CD4, and CD8 lymphocytes were more common as the disease worsened (All P < 0.05). Methylprednisolone (mPSL) was applied to 31 (47.69%) patients with pneumonia, including 10 (31.25%) general, 8 (100%) severe, and 13 (86.67%) critical patients, respectively. Corticosteroids inhibited Interleukin-6(IL-6) production (P = 0.0215) but did not affect T lymphocyte (P = 0.0796). There was no significant difference between patients using lower dose (≤ 2 mg/kg day) and higher dose (> 2 mg/kg day) mPSL in inhibiting IL-6 production (P = 0.5856). Thirty of 31 patients (96.77%) had stopped mPSL due to improvement of pneumonia. Virus RNA clearance time lengthened with disease progression (P = 0.0001). In general type, there was no significant difference in virus clearance time between patients with (15, 12-19 days) and without (14.5, 11-18 days) (P = 0.7372) mPSL use. Lymphocyte, especially T lymphocyte, in severe and critical patients showed a dramatic decrease. Application of lower dose corticosteroids (≤ 2 mg/kg day) could inhibit IL-6 production (a representative of cytokines) as effectively as a higher dose. Proper use corticosteroids in general type patients did not delay virus clearance.

RESUMO

BACKGROUND: Concerns exist regarding the analgesia effect and safety of multiple versus single doses dexamethasone in unicompartmental knee arthroplasty. There is an urgent need of studies that efficiently control for confounding, conduct comprehensive and consecutive observation of potential risks of the dexamethasone administration, and investigate its clinical applicability. We thus further designed a randomized controlled study to assess the different dose of dexamethasone on postoperative pain and complications in patients undergoing unicompartmental knee arthroplasty. METHODS: This randomized, prospective, controlled study was carried out between January 2018 and August 2019. It was approved by the institutional review board in our hospital (HBRM2020013). A total of 80 patients were randomly assigned to each group: the study group (n = 40) and the control group (n = 40). All surgical procedures were performed by a similar orthopedic surgeon. In the study group, patients received intravenously 20 mg dexamethasone (4 mL, Tianjin Kingyork group Co., Ltd., China) just after the anesthesia, and repeated at 24 hours after the surgery. Patients in the control group received intravenously 10 mg dexamethasone solution (2 mL) just after the anesthesia, and repeated at 24 hours after the surgery. CRP, IL-6, VAS pain scores at rest and walking, the VAS scores of nausea, and the incidence of postoperative vomiting and nausea (POVN) were recorded at 24, 48, and 72 hours postoperatively. CONCLUSION: We hypothesized that patients receiving multiple doses of dexamethasone was associated with better outcomes compared with patients receiving single dose of dexamethasone. TRIAL REGISTRATION: This study protocol was registered in Research Registry (researchregistry5770).
