RESUMO

During an earlier multicenter, open-label, randomized controlled trial designed to evaluate the effectiveness of high-dose inhaled ciclesonide in patients with asymptomatic or mild coronavirus disease 2019 (COVID-19), we observed that worsening of shadows on CT without worsening of clinical symptoms was more common with ciclesonide. The present study sought to determine if an association exists between worsening CT shadows and impaired antibody production in patients treated with inhaled ciclesonide. Eighty-nine of the 90 patients in the original study were prospectively enrolled. After exclusions, there were 36 patients each in the ciclesonide and control groups. We analyzed antibody titers against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleocapsid protein at various time points. Changes in viral load during treatment were compared. There was no significant difference in age, sex, body mass index, background clinical characteristics, or symptoms between the two groups. Although evaluation on day 8 suggested a greater tendency for worsening shadows on CT in the ciclesonide group (p = 0.072), there was no significant difference between them in the ability to produce antibodies (p = 0.379) or the maximum antibody titer during the clinical course. In both groups, worsening CT shadows and higher viral loads were observed on days 1-8, suggesting ciclesonide does not affect clearance of the virus (p = 0.134). High-dose inhaled ciclesonide did not impair production of antibodies against SARS-CoV-2 or affect elimination of the virus, suggesting that this treatment can be used safely in patients with COVID-19 patients who use inhaled steroids for asthma and other diseases.

RESUMO

BACKGROUND: The successful management of patients infected with coronavirus disease 2019 (COVID-19) with inhaled ciclesonide has been reported, however few studies have investigated its application among hospitalized patients. METHODS: This retrospective cohort study enrolled all adult patients admitted to our hospital with confirmed COVID-19 infection from May to June 2021. Critical patients who received mechanical ventilation within 24 h after admission and those who started ciclesonide more than 14 days after symptom onset were excluded. The in-hospital mortality rate was compared between those who did and did not receive inhaled ciclesonide. RESULTS: A total of 269 patients were enrolled, of whom 184 received inhaled ciclesonide and 85 did not. The use of ciclesonide was associated with lower in-hospital mortality (7.6% vs. 23.5%, p = 0.0003) and a trend of shorter hospital stay (12.0 (10.0-18.0) days vs. 13.0 (10.0-25.3) days, p = 0.0577). In subgroup analysis, the use of inhaled ciclesonide significantly reduced mortality in the patients with severe COVID-19 infection (6.8% vs. 50.0%, p < 0.0001) and in those with a high risk of mortality (16.4% vs. 43.2%, p = 0.0037). The use of inhaled ciclesonide also reduced the likelihood of receiving mechanical ventilation in the patients with severe COVID-19 infection. After multivariate analysis, inhaled ciclesonide remained positively correlated with a lower risk of in-hospital mortality (odds ratio: 0.2724, 95% confidence interval: 0.087-0.8763, p = 0.0291). CONCLUSIONS: The use of inhaled ciclesonide in hospitalized patients with COVID-19 infection can reduce in-hospital mortality. Further randomized studies in patients with moderate to severe COVID-19 infection are urgently needed.

RESUMO

Autism spectrum disorder is a neurodevelopmental disorder marked by repetitive behaviour, challenges in verbal and non-verbal communication, poor socio-emotional health, and cognitive impairment. An increased level of signal transducer and activator of transcription 3 (STAT3) and a decreased level of peroxisome proliferator-activated receptor (PPAR) gamma have been linked to autism pathogenesis. Guggulsterone (GST) has a neuroprotective effect on autistic conditions by modulating these signalling pathways. Consequently, the primary objective of this study was to examine potential neuroprotective properties of GST by modulating JAK/STAT and PPAR-gamma levels in intracerebroventricular propionic acid (ICV PPA) induced experimental model of autism in adult rats. In this study, the first 11 days of ICV-PPA injections in rats resulted in autism-like behavioural, neurochemical, morphological, and histopathological changes. The above modifications were also observed in various biological samples, including brain homogenate, CSF, and blood plasma. GST was also observed to improve autism-like behavioural impairments in autistic rats treated with PPA, including locomotion, neuromuscular coordination, depression-like behaviour, spatial memory, cognition, and body weight. Prolonged GST treatment also restored neurochemical deficits in a dose-dependent manner. Chronic PPA administration increased STAT3 and decreased PPAR gamma in autistic rat brain, CSF, and blood plasma samples, which were reversed by GST. GST also restored the gross and histopathological alterations in PPA-treated rat brains. Our results indicate the neuroprotective effects of GST in preventing autism-related behavioural and neurochemical alterations.

RESUMO

Importance: Systemic corticosteroids are commonly used in treating severe COVID-19. However, the role of inhaled corticosteroids in the treatment of patients with mild to moderate disease is less clear. Objective: To determine the efficacy of the inhaled steroid ciclesonide in reducing the time to alleviation of all COVID-19-related symptoms among nonhospitalized participants with symptomatic COVID-19 infection. Design, Setting, and Participants: This phase 3, multicenter, double-blind, randomized clinical trial was conducted at 10 centers throughout the US and assessed the safety and efficacy of a ciclesonide metered-dose inhaler (MDI) for treating nonhospitalized participants with symptomatic COVID-19 infection who were screened from June 11, 2020, to November 3, 2020. Interventions: Participants were randomly assigned to receive ciclesonide MDI, 160 µg per actuation, for a total of 2 actuations twice a day (total daily dose, 640 µg) or placebo for 30 days. Main Outcomes and Measures: The primary end point was time to alleviation of all COVID-19-related symptoms (cough, dyspnea, chills, feeling feverish, repeated shaking with chills, muscle pain, headache, sore throat, and new loss of taste or smell) by day 30. Secondary end points included subsequent emergency department visits or hospital admissions for reasons attributable to COVID-19. Results: A total of 413 participants were screened and 400 (96.9%) were enrolled and randomized (197 [49.3%] in the ciclesonide arm and 203 [50.7%] in the placebo arm; mean [SD] age, 43.3 [16.9] years; 221 [55.3%] female; 2 [0.5%] Asian, 47 [11.8%] Black or African American, 3 [0.8%] Native Hawaiian or other Pacific Islander, 345 [86.3%] White, and 1 multiracial individuals [0.3%]; 172 Hispanic or Latino individuals [43.0%]). The median time to alleviation of all COVID-19-related symptoms was 19.0 days (95% CI, 14.0-21.0) in the ciclesonide arm and 19.0 days (95% CI, 16.0-23.0) in the placebo arm. There was no difference in resolution of all symptoms by day 30 (odds ratio, 1.28; 95% CI, 0.84-1.97). Participants who were treated with ciclesonide had fewer subsequent emergency department visits or hospital admissions for reasons related to COVID-19 (odds ratio, 0.18; 95% CI, 0.04-0.85). No participants died during the study. Conclusions and Relevance: The results of this randomized clinical trial demonstrated that ciclesonide did not achieve the primary efficacy end point of reduced time to alleviation of all COVID-19-related symptoms. Trial Registration: ClinicalTrials.gov Identifier: NCT04377711.

RESUMO

Background: Ciclesonide (CIC) is an inhaled corticosteroid (ICS) approved for the maintenance treatment of asthma in patients ages ≥ 12 years. The prodrug aspect of CIC is associated with a safety profile that may make it ideal for children. Objective: The objective was to summarize efficacy results from the eight phase III, randomized, double-blind, controlled trials in children with asthma conducted during CIC clinical development. Methods: Four trials compared CIC 40, 80, or 160 µg/day with placebo. Two trials compared CIC 160 µg/day with fluticasone propionate 200 µg/day, one trial compared CIC 80 or 160 µg/day with fluticasone 200 µg/day, and one trial compared CIC 160 µg/day with budesonide 400 µg/day. Results: The primary end point was met by at least two CIC doses versus placebo in the trials in which the primary end point was the change from baseline in lung function outcome (forced expiratory volume in 1 second [FEV1] % predicted or morning peak expiratory flow [PEF]). A trial that compared CIC with placebo did not meet the primary end point of superiority in time-to-first severe wheeze exacerbation or lack of improvement. The primary end point of noninferiority to the active control (fluticasone or budesonide) in the change from baseline in a lung function outcome (FEV1, morning PEF, evening PEF) was met with the CIC 160-µg dose in all active control trials. CIC generally demonstrated statistically significant improvements in forced expiratory flow at 25%-75% of forced vital capacity, asthma symptoms, rescue medication use, and asthma control when compared with placebo and noninferiority for these outcomes compared with fluticasone or budesonide. Conclusion: In children with asthma, once-daily CIC significantly improved large and small airway function, asthma symptoms, and asthma control, and reduced rescue medication use compared with placebo. CIC was comparable with other ICS used to treat asthma in children, which demonstrated its worth for the pediatric population.

RESUMO

OBJECTIVE: To determine if inhaled and intranasal ciclesonide are superior to placebo at decreasing respiratory symptoms in adult outpatients with covid-19. DESIGN: Randomised, double blind, placebo controlled trial. SETTING: Three Canadian provinces (Quebec, Ontario, and British Columbia). PARTICIPANTS: 203 adults aged 18 years and older with polymerase chain reaction confirmed covid-19, presenting with fever, cough, or dyspnoea. INTERVENTION: Participants were randomised to receive either inhaled ciclesonide (600 µg twice daily) and intranasal ciclesonide (200 µg daily) or metered dose inhaler and nasal saline placebos for 14 days. MAIN OUTCOME MEASURES: The primary outcome was symptom resolution at day 7. Analyses were conducted on the modified intention-to-treat population (participants who took at least one dose of study drug and completed one follow-up survey) and adjusted for stratified randomisation by sex. RESULTS: The modified intention-to-treat population included 203 participants: 105 were randomly assigned to ciclesonide (excluding two dropouts and one loss to follow-up) and 98 to placebo (excluding three dropouts and six losses to follow-up). The median age was 35 years (interquartile range 27-47 years) and 54% were women. The proportion of participants with resolution of symptoms by day 7 did not differ significantly between the intervention group (42/105, 40%) and control group (34/98, 35%); absolute adjusted risk difference 5.5% (95% confidence interval -7.8% to 18.8%). Results might be limited to the population studied, which mainly included younger adults without comorbidities. The trial was stopped early, therefore could have been underpowered. CONCLUSION: Compared with placebo, the combination of inhaled and intranasal ciclesonide did not show a statistically significant increase in resolution of symptoms among healthier young adults with covid-19 presenting with prominent respiratory symptoms. As evidence is insufficient to determine the benefit of inhaled and intranasal corticosteroids in the treatment of covid-19, further research is needed. TRIAL REGISTRATION: ClinicalTrials.gov NCT04435795.

RESUMO

BACKGROUND: Eosinophilic esophagitis (EoE) is a chronic allergen-mediated disease of the esophagus. Pharmacologic treatment has largely relied on repurposing corticosteroids. Ciclesonide (CIC) is a corticosteroid for the treatment of asthma with biochemical properties that improve topical potency. OBJECTIVE: To determine whether CIC decreased clinicopathological features of EoE. METHODS: We performed a retrospective cohort study of patients with EoE treated with CIC at a pediatric hospital from 2010 to 2019. Data were extracted from the electronic health record. Patients who were prescribed CIC with pre- and post-CIC endoscopic and histological data available were included for analysis. RESULTS: A total of 281 patients were treated with CIC and 81 met criteria for inclusion. Use of CIC was associated with reduced symptoms including dysphagia (P < .001), abdominal pain (P < .001), vomiting (P = .01), heartburn (P = .02), and behavior changes (P = .02). Average composite endoscopic reference scores decreased from 2.54 to 1.37 (P < .001), with improvement in exudates, edema, and furrows (all P < .001). Peak eosinophil counts decreased from 48 to 23 eosinophils/hpf (P < .001). Forty-three patients (53%) achieved remission (<15 eosinophils/hpf). Esophageal Candida was reported in 1 patient. Fasting morning cortisol concentrations were low in 10 of 31 patients tested. Six of these 10 patients had abnormal adrenocorticotropic hormone stimulation testing, 5 of 6 diagnosed with adrenal insufficiency before transition to CIC and 3 of 6 with subsequent normalization of adrenal function on CIC therapy. CONCLUSIONS: Patients with EoE treated with CIC experienced significant reductions in clinicopathological features of EoE. CIC can be considered an alternative therapy in patients with known adrenal insufficiency or at risk of developing adrenal insufficiency.

RESUMO

We describe a case of coronavirus disease 2019 (COVID-19) in a patient with mixed cellularity classical Hodgkin lymphoma (cHL) undergoing brentuximab vedotin, doxorubicin, vinblastine, and dacarbazine (A+AVD) therapy. A 43-year-old man presented to our hospital with a complaint of fever, for which he was diagnosed with COVID-19 after a positive polymerase chain reaction (PCR) test for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and antiviral therapy with favipiravir and ciclesonide was started subsequently. The fever persisted for the first few days of treatment, but his respiratory status was stable, and he became asymptomatic and afebrile on day 9. Although the PCR tests remained positive, he met the updated discharge criteria of the World Health Organization (WHO) on day 12. However, his fever recurred, and his condition worsened on day 16. A chest X-ray showed a new opacity. It is likely that favipiravir and ciclesonide treatment probably did not completely eliminate the virus in the patient, and therefore the infection persisted. We added remdesivir from day 21, and the improvement was remarkable. He was discharged on day 29 after two consecutive PCR test results were negative. PCR tests are not mandatory for the updated WHO discharge criteria. However, even after antiviral therapy, COVID-19 patients with hematologic malignancies may have prolonged active infection with impaired viral excretion. Depending on the background disease and comorbidities, there may be some patient populations for whom it is not appropriate to simply comply with the current discharge criteria. Therefore, more emphasis may be needed on PCR examinations.

RESUMO

Multiple Sclerosis (MS) is a progressive neurodegenerative disease with clinical signs of neuroinflammation and the central nervous system's demyelination. Numerous studies have identified the role of the Janus kinase (JAK)/signal transducer and activator of transcription (STAT) overexpression and the low level of peroxisome proliferator-activated receptor-gamma (PPAR-γ) in MS pathogenesis. Guggulsterone (GST), an active component derived from 'Commiphora Mukul,' has been used to treat various diseases. Traditional uses indicate that GST is a suitable agent for anti-inflammatory action. Therefore, we assessed the therapeutic potential of GST (30 and 60 mg/kg) in ethidium bromide (EB) induced demyelination in experimental rats and investigated the molecular mechanism by modulating the JAK/STAT and PPAR-γ receptor signaling. Wistar rats were randomly divided into six groups (n = 6). EB (0.1%/10 µl) was injected selectively in the intracerebropeduncle (ICP) region for seven days to cause MS-like manifestations. The present study reveals that long-term administration of GST for 28 days has a neuroprotective effect by improving behavioral deficits (spatial cognition memory, grip, and motor coordination) associated with lower STAT-3 levels. While elevating PPAR-γ and myelin basic protein levels in rat brains are consistent with the functioning of both signaling pathways. Also, GST modulates the neurotransmitter level by increasing Ach, dopamine, serotonin and by reducing glutamate. Moreover, GST ameliorates inflammatory cytokines (TNF, IL-1ß), and oxidative stress markers (AchE, SOD, catalase, MDA, GSH, nitrite). In addition, GST prevented apoptosis, as demonstrated by the reduction of caspase-3 and Bax. Simultaneously, Bcl-2 elevation and the restoration of gross morphology alterations are also recovered by long-term GST treatment. Therefore, it can be concluded that GST may be a potential alternative drug candidate for MS-related motor neuron dysfunctions.

RESUMO

Programmed death-ligand 1 (PD-L1) is an immune checkpoint molecule, that is overexpressed in non-small cell lung cancer (NSCLC) and has been associated with the response to anti-PD-1/PD-L1 immunotherapy. Z-guggulsterone (Z-GS), an active compound extracted from the gumresin of the Commiphora mukul tree, has been shown to have anti-tumor effects in NSCLC in our previous study. However, whether Z-GS could affect PD-L1 expression levels in tumor cells remains unknown. In this study, we verified the inhibitory effects of Z-GS on NSCLC cell viability and cell cycle progression in vitro, and mouse Lewis lung carcinoma (LLC) tumor growth in vivo. Notably, Z-GS treatment increased PD-L1 surface and mRNA expression levels, and gene transcription in NSCLC cells, in a dose- and time-dependent manner. Mechanistic experiments showed that the upregulation of PD-L1 was mediated, partly by farnesoid X receptor inhibition, and partly by the activation of the Akt and Erk1/2 signaling pathways in Z-GS-treated NSCLC cells. In vivo, Z-GS treatment dose-dependently increased PD-L1 expression levels in mouse LLC tumor models. Overall, our findings demonstrated a promoting role for Z-GS in PD-L1 expression in NSCLC and provided mechanistic insights, that may be used for further investigation into synergistic combined therapies.

RESUMO

As no definitive therapy or vaccine is yet available for COVID-19, in a desperate attempt repurposed drugs are being explored as an option. A drug repurposing study identified Ciclesonide as a potential candidate. We reviewed the available evidence and clinical trials on the use of Ciclesonide in COVID-19. At present the evidence is limited to a report of three cases. However, five clinical trials are underway, and their results will help in elucidating the role of Ciclesonide in COVID-19.

RESUMO

PURPOSE: To describe an atypical case of acute retinal pigment epitheliitis including spectral domain optical coherence tomography (OCT) and OCT angiography features. METHODS: We report a 41-year-old woman with 3 episodes of acute retinal pigment epitheliitis over a 3-year period. Spectral domain OCT and OCT angiography images were acquired with Cirrus 5,000 spectral domain OCT. RESULTS: Although acute retinal pigment epitheliitis is described as a benign, self-limited pathology, as this case shows, recurrences are possible. OCT angiography shows a choriocapillaris alteration and further recovery during the acute episodes. CONCLUSION: Acute retinal pigment epitheliitis can present as a recurrent disease.

RESUMO

We treated two patients with severe respiratory failure due to coronavirus disease 2019 (COVID-19). Case 1 was a 73-year-old woman, and Case 2 was a 65-year-old-man. Neither of them had a history of autoimmune disease. Chest computed tomography scans before the antiviral therapy showed bilateral multiple patchy ground-glass opacities (GGO) consistent with COVID-19 pneumonia. The GGO regressed over the course of the antiviral treatment; however, new non-segmental patchy consolidations emerged, which resembled those of interstitial lung disease (ILD), specifically collagen vascular disease-associated ILD. We tested the patients' sera for autoantibodies and discovered that both patients had high anti-SSA/Ro antibody titers. In Case 1, the patient recovered with antiviral therapy alone. However, in Case 2, the patient did not improve with antiviral therapy alone but responded well to corticosteroid therapy (methylprednisolone) and made a full recovery. The relationship between some immunological responses and COVID-19 pneumonia exacerbation has been discussed previously; our discovery of the elevation of anti-SSA/Ro antibodies suggests a contribution from autoimmunity functions of the immune system. Although it is unclear whether the elevation of anti-SSA/Ro antibodies was a cause or an outcome of aggravated COVID-19 pneumonia, we hypothesize that both patients developed aggravated the COVID-19 pneumonia due to an autoimmune response. In COVID-19 lung injury, there may be a presence of autoimmunity factors in addition to the known effects of cytokine storms. In patients with COVID-19, a high level of anti-SSA/Ro52 antibodies may be a surrogate marker of pneumonia severity and poor prognosis.

RESUMO

Full house nephropathy is defined as the simultaneous detection of IgA, IgG, IgM, C3, and C1q deposits by immunofluorescence, usually indicating lupus nephritis. There are patients with this immunofluorescence pattern, but with negative autoantibody serology, which means they cannot be diagnosed with systemic lupus erythematosus. Patients presenting with full house nephropathy but no other criteria for lupus are diagnosed as having nonlupus full house nephropathy. Here, we describe two cases: A male patient who debuted with rapidly progressive glomerulonephritis and a female patient with nephrotic syndrome. Both had negative autoantibody serology, findings in the renal biopsy of class IV lupus nephritis and afull house immunofluorescence pattern. Histological findings in non-lupus full house nephropathy are similar to those in lupus nephritis and, probably, similar physiopathological bases. However, prospective studies are needed to determine risk factors and the renal prognosis and to make suggestions for specific treatments.


La nefropatía full house se refiere a la detección simultánea de depósitos de IgA, IgG, IgM, C3 y C1q en la inmunofluorescencia, lo que generalmente indica la presencia de nefritis lúpica. Hay pacientes con este patrón de inmunofluorescencia, pero con serología negativa para autoanticuerpos, por lo que no se les puede diagnosticar un lupus eritematoso sistémico. Este tipo de nefropatía, en la que no se presentan otros criterios para lupus, se denomina nefropatía full house no lúpica. En esta presentación, se describen dos casos: un paciente que ingresó con una glomerulonefritis rápidamente progresiva y una paciente con síndrome nefrótico, ambos con serología negativa para autoanticuerpos, hallazgos en la biopsia renal indicativos de nefritis lúpica de clase IV y un patrón full house en la inmunofluorescencia. La nefropatía full house no lúpica tiene rasgos histológicos similares a los de la nefritis lúpica y, probablemente, sus bases fisiopatológicas son parecidas. Sin embargo, se necesitan estudios prospectivos para conocer los factores de riesgo y el pronóstico renal, y poder hacer sugerencias sobre tratamientos específicos.

RESUMO

We report a coronavirus disease 2019 (COVID-19) case with rheumatoid arthritis taking iguratimod. The patient who continued iguratimod therapy without dose reduction was treated with ciclesonide had an uneventful clinical course, but prolonged detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was observed after resolution of symptoms. The effects of disease-modifying antirheumatic drugs (DMARDs) and ciclesonide on clinical course and viral shedding remain unknown and warrant further investigation.
