Ultrasound-guided procedures for plantar fasciitis: a randomized clinical study.

BACKGROUND: Corticosteroid injections are commonly used for the treatment of plantar fasciitis. In recent years, ultrasound-guided multipuncture treatment of the fascia has been described in the literature. Our study aimed to compare the effectiveness of these two techniques in the treatment of plantar fasciitis. METHODS: The outcomes achieved over 120 days following the use of these techniques to treat plantar fasciitis were examined. A total of 81 patients were randomly selected for the study; 41 were treated with ultrasound-guided multipuncture and 40 with ultrasound-guided corticosteroid injection. Clinical examinations and ultrasound assessments were performed before treatment and at 30, 60 and 120 days post-treatment. Clinical assessments included the use of a visual analog scale (VAS) to record pain and the Foot Function Index (FFI) to evaluate function. Ultrasound was used to measure the thickness of the plantar fascia. RESULTS: Both the ultrasound-guided multipuncture and corticosteroid injection techniques were associated with significant functional and echographic improvements at 4 months post-treatment (P < 0.001). Pain did not improve significantly after 120 days with ultrasound-guided corticosteroid injection, whereas significant pain reduction was observed with ultrasound-guided multipuncture. CONCLUSION: Corticosteroid injection provides better short-term results in terms of VAS pain and FFI scores. However, ultrasound-guided multipuncture shows superior outcomes in VAS pain and FFI scores at 120 days.

Retrospective Evaluation of Survival and Prognostic Factors in Immune Thrombocytopenia: A Single-Center and Cross-Sectional Study.

Background and Objectives: Immune thrombocytopenia (ITP) is an autoimmune disease characterized by the autoantibody-mediated destruction of platelets. The treatment of ITP aims to maintain a sufficient platelet count to prevent bleeding. First-line treatment options include corticosteroids and intravenous immunoglobulin (IVIg), while second-line treatments include splenectomy, rituximab and other immunosuppressive agents, and thrombopoietin (TPO) receptor agonists. This study aims to discuss the treatment methods and results from 100 patients with ITP at the Mugla Training and Research Hospital through a pharmacological approach. Materials and Methods: Demographic characteristics, clinical findings, bone marrow aspiration and biopsy results, and treatments and treatment responses at the time of diagnosis of the 100 patients with ITP who were treated and followed up in the period 2015-2023 were evaluated retrospectively. Results: In the third month after treatment, the overall response percentage was 100% in patients who received steroids only and 88% in patients who received IVIg treatment alone or in combination with steroids (p > 0.05). The most preferred second-line treatments were splenectomy (41%), eltrombopag (26%), and rituximab (10%). Bone marrow biopsy was performed in 54% of patients, where 35.1% showed increased megakaryocytes, 44.4% adequate megakaryocytes, and 14.8% decreased megakaryocytes. It is noted that eltrombopag and rituximab, in particular, yield higher complete remission rates than immunosuppressive drugs. Conclusions: Considering the side effects of immunosuppressive medications, IVIg, splenectomy, and steroid therapy, the use of new agents such as eltrombopag, which are easily tolerated and have a lower risk of side effects, is expected to increase.

Expedited liver transplantation as first-line therapy for severe alcohol hepatitis: ELFSAH; deferring corticosteroids in the sickest subset of patients.

BACKGROUND & AIMS: Severe alcohol-associated hepatitis (SAH) represents a lethal subset of alcohol-associated liver disease. Although corticosteroids are recommended by guidelines, their efficacy and safety remain questionable and so liver transplantation (LT) has been increasingly utilized. The timing and indication of corticosteroid use, specifically in patients being considered for LT requires further clarification. METHODS: A retrospective analysis was conducted on 256 patients with SAH between 2018 and 2022 at a single US center. RESULTS: Twenty of these patients underwent LT. Of the 256 patients, 38% had what we termed "catastrophic" SAH, defined as a MELD-Na ≥35 and/or discriminant function (DF) ≥100, which carried a mortality of 90% without LT. Compared with 100 matched controls, patients undergoing LT exhibited a one-year survival rate of 100% versus 35% (p < .0005). LT provided an absolute risk reduction of 65%, with a number needed to treat of 1.5. Steroid utilization in the entire cohort was 19% with 60% developing severe complications. Patients administered steroids were younger with lower MELD and DF scores. Only 10% of those prescribed steroids derived a favorable response. Sustained alcohol use post-LT was 20%. CONCLUSIONS: We propose ELFSAH: Expedited LT as First Line Therapy for SAH; challenging the current paradigm with recommendations to defer steroids in patients with "catastrophic" SAH (defined as: MELD-Na ≥35 and/or DF ≥100). Patients should be seen urgently by hepatology, transplant surgery, psychiatry and social work. Patients without an absolute contraindication should be referred for LT as first-line therapy during their index admission.

Comparison of Infection Risks Between Various Inhaled and Intranasal Corticosteroids: A Pharmacovigilance Analysis Based on the FAERS Database.

Purpose: This study conducted a pharmacovigilance analysis based on the FDA Adverse Event Reporting System (FAERS) database to compare the infection risk of inhaled or nasal Beclomethasone, Fluticasone, Budesonide, Ciclesonide, Mometasone, and Triamcinolone Acetonide. Methods: We used proportional imbalance analysis to evaluate the correlation between ICS /INCs and infection events. The data was extracted from the FAERS database from April 2015 to September 2023. Further analysis was conducted on the clinical characteristics, site of infection, and pathogenic bacteria of ICS and INCs infection adverse events (AEs). We used bubble charts to display their top 5 infection adverse events. Results: We analyzed 21,837 reports of infection AEs related to ICS and INCs, with an average age of 62.12 years. Among them, 61.14% of infection reports were related to females. One-third of infections reported to occur in the lower respiratory tract with Fluticasone, Budesonide, Ciclesonidec, and Mometasone; over 40% of infections reported by Triamcinolone Acetonide were eye infections; the rate of oral infections caused by Beclomethasone were 7.39%. The reported rates of fungal and viral infections caused by beclomethasone were 21.15% and 19.2%, respectively. The mycobacterial infections caused by Budesonide and Ciclesonidec account for 3.29% and 2.03%, respectively. Bubble plots showed that the ICS group had more fungal infections, oral infections, pneumonia, tracheitis, etc. The INCs group had more eye symptoms, rhinitis, sinusitis, nasopharyngitis, etc. Conclusion: Women who use ICS and INCs are more prone to infection events. Compared to Budesonide, Fluticasone seemed to have a higher risk of pneumonia and oral candidiasis. Mometasone might lead to more upper respiratory tract infections. The risk of oral infection was higher with Beclomethasone. Beclomethasone causes more fungal and viral infections, while Ciclesonide and Budesonide are more susceptible to mycobacterial infections.

The use of antenatal corticosteroids in preterm labour for the prevention of perinatal mortality in hospitals in Tanzania.

Background: Antenatal corticosteroids (ACS) are given to pregnant women at risk of preterm delivery to hasten the maturation of the lungs, lowering the risk of newborn respiratory distress syndrome (RDS) and perinatal mortality. Objective: The aim of this study was to determine whether exposure to ACS was associated with lower rates of perinatal mortality and RDS in preterm infants delivered by women with preterm labour. Methods: This is a secondary analysis of data from four hospitals in Mwanza, Tanzania. All singletons and twins born to women who were in preterm labour between July 2019 and February 2020 and delivered in-hospital between 24 and 34 weeks of gestation were included. Data were recorded from participants' medical records and analysed using STATA Version 14. Results: Over an eight-month period, 588 preterm infants were delivered to 527 women. One hundred and ninety (36.1%) women were given ACS. Infants who were exposed to ACS in utero had a lower rate of perinatal mortality (6.8% vs 19.1%) and RDS (12.3% vs 25.9%) compared to those not exposed to ACS. In adjusted multivariable models, ACS exposure was related to a lower risk of perinatal mortality, aRR 0.23 (95% CI 0.13 - 0.39), and RDS, aRR 0.45 (95% CI 0.30 - 0.68). Conclusion: ACS significantly reduced the risk of perinatal mortality and RDS among preterm infants exposed to ACS in utero and delivered by women in preterm labour. The use of ACS should be encouraged in low-resource settings where preterm birth is prevalent to improve perinatal outcomes.

Warfarin-related nephropathy: unveiling the hidden dangers of anticoagulation.

Warfarin-related nephropathy (WRN) is defined as acute kidney injury subsequent to excessive anticoagulation with warfarin. Patients with mechanical prosthetic valves require long-term anticoagulant therapy. Nonetheless, warfarin remains the sole available option for anticoagulant therapy. Consequently, patients with mechanical prosthetic valves constitute a special group among the entire anticoagulant population. The present study recorded two cases of patients who had undergone mechanical prosthetic valve surgery and were receiving warfarin therapy. They presented to the hospital with gross hematuria and progressive creatinine levels. Notably, their international normalized ratio (INR) did not exceed three. Subsequent renal biopsies confirmed WRN with IgA nephropathy. The two patients continued to receive warfarin as anticoagulation therapy and were prescribed oral corticosteroids and cyclophosphamide, which resulted in improved renal function during the follow-up. Based on a review of all relevant literature and the present study, we proposed a new challenge: must elevated INR levels be one of the criteria for clinical diagnosis of WRN? Perhaps some inspiration can be drawn from the present article.

Corticosteroids for improving patient-relevant outcomes in HELLP syndrome: a systematic review and meta-analysis.

BACKGROUND: We conducted this updated systematic review to assess the effects of corticosteroids vs. placebo or no treatment for improving patient-relevant outcomes in hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome. METHODS: CENTRAL, MEDLINE/PubMed, Web of Science, and Scopus, from the date of inception of the databases to February 3, 2024 were searched. Reference lists of included studies and systematic reviews were thoroughly searched. We included RCTs that enrolled women with HELLP syndrome, whether antepartum or postpartum, to receive any corticosteroid versus placebo or no treatment. No language or publication date restrictions were made. We used a dual independent approach for screening titles and abstracts, full text screening, and data extraction. Risk of bias was assessed in the included studies using Cochrane's RoB 2 tool. Pairwise meta-analyses were conducted, where two or more studies met methodological criteria for inclusion. GRADE approach was used to assess certainty of evidence for the pre-specified outcomes. RESULTS: Fifteen trials (821 women) compared corticosteroids with placebo or no treatment. The effect of corticosteroids is uncertain for the primary outcome i.e., maternal death (risk ratio [RR] 0.77, 95% confidence interval [CI] 0.25 to 2.38, very low certainty evidence). Out of 6 studies reporting maternal death, 5 were judged overall to have "low risk" of bias. The effect of corticosteroids is also uncertain for other important outcomes including pulmonary edema (RR 0.70, 95% CI 0.23 to 2.09), dialysis (RR 3, 95% CI 0.13 to 70.78), liver morbidity (hematoma, rupture, and failure; RR 0.22, 95% CI 0.03 to 1.83), or perinatal death (0.64, 95% CI 0.21 to 1.97) because of very low certainty evidence. Low certainty evidence suggests that corticosteroids have little or no effect on the need for platelet transfusion (RR 0.98, 95% CI 0.60 to 1.60) and may result in a slight reduction in acute renal failure (RR 0.67, 95% CI 0.40 to 1.12). Subgroup and sensitivity analyses showed results that were similar to the primary synthesis. CONCLUSIONS: In women with HELLP syndrome, the effect of corticosteroids vs. placebo or no treatment is uncertain for patient-relevant outcomes including maternal death, maternal morbidity, and perinatal death. These uncertainties regarding this critical question should be addressed by adequately powered rigorous trials. SYSTEMATIC REVIEW REGISTRATION: Center for Open Science, osf.io/yzku5.

[Anti-Neutrophil Cytoplasmic Antigens (ANCA)-associated vasculitis: Current therapeutics]. / Vascularites associées aux anticorps anti-cytoplasme des polynucléaires neutrophiles (ANCA) : actualités thérapeutiques.

ANCA-associated vasculitis brings together three diseases, granulomatosis with polyangiitis, microscopic polyangiitis and eosinophilic granulomatosis with polyangiitis. This group of diseases has benefited over the last 3 decades from major therapeutic advances both in terms of therapeutic strategies and availability of new drugs, mainly for targeted therapies. Treatments, whether conventional or not, include an induction phase followed by a maintenance phase. Induction treatment today poses few problems. It is essentially based on the combination of corticosteroids and rituximab or cyclophosphamide. Remission is achieved in less than 6 months and maintenance treatment, preventing relapses, is then started. We showed that the best maintenance treatment was rituximab, surpassing the efficacy of methotrexate or azathioprine. During this phase, corticosteroid therapy is stopped or given at a very small dose. In Eosinophilic Granulomatosis with Polyangiitis (GEPA), the strategy is slightly different and there is a lack of prospective trials to demonstrate the benefits of rituximab or mepolizumab (anti-IL5) in inducing remission. Regarding maintenance treatment, prolonged corticosteroid therapy (orally and/or inhaled) is often necessary to control asthmatic disease. Only mepolizumab has shown its ability to prevent relapses and reduce the dose of corticosteroids controlling asthma. The current questions posed by maintenance treatment are its duration which could be variable and adapted to the risk of relapse and the risks induced by prolonged immunosuppression, particularly infectious.

Title: Vascularites associées aux anticorps anti-cytoplasme des polynucléaires neutrophiles (ANCA) : actualités thérapeutiques. Abstract: Les vascularites associées aux anticorps anti-cytoplasme des polynucléaires neutrophiles (ANCA) réunissent trois maladies, la granulomatose avec polyangéite, la polyangéite microscopique et la granulomatose éosinophilique avec polyangéite. Ce groupe de maladies a bénéficié au cours des trois dernières décennies d'avancées thérapeutiques majeures tant en termes de stratégies thérapeutiques que de mise à disposition de nouveaux médicaments, essentiellement pour des thérapies ciblées. Les traitements, conventionnels ou non, comprennent une phase d'induction suivie d'une phase d'entretien. Le traitement d'induction pose aujourd'hui peu de problèmes. Il est essentiellement fondé sur l'association corticoïdes et rituximab ou cyclophosphamide. La rémission est obtenue en moins de 6 mois et un traitement d'entretien, préventif des rechutes, est alors initié. Nous avons montré que le meilleur traitement d'entretien était le rituximab, surpassant l'effet du méthotrexate ou de l'azathioprine. Durant cette phase, la corticothérapie est arrêtée ou donnée à très petite dose. Dans la granulomatose éosinophilique avec polyangéite (GEPA), la stratégie est un peu différente et les essais prospectifs manquent pour démontrer l'intérêt du rituximab ou du mépolizumab (anti-IL5) en induction de la rémission. En traitement d'entretien, une corticothérapie prolongée (par voie orale et/ou inhalée) est souvent nécessaire pour contrôler la maladie asthmatique. Seul le mépolizumab a montré sa capacité à prévenir les rechutes et à réduire la dose de corticoïdes contrôlant l'asthme. Les questions actuelles que pose le traitement d'entretien sont notamment sa durée qui pourrait être variable et adaptée au risque de rechute et les risques induits par l'immunodépression prolongée, notamment infectieux.

The long-term outcomes of mepolizumab treatment at 100 mg dose on idiopathic chronic eosinophilic pneumonia: A real-life experience.

Background: The standard therapeutic regimen for idiopathic chronic eosinophilic pneumonia (ICEP) involves the administration of oral corticosteroids (OCS). However, a notable proportion of individuals experience recurrent episodes after the tapering or cessation of OCS during the course of ICEP. There has been a growing interest in exploring alternative treatment modalities for patients with ICEP at heightened risk of relapse. Objective: The aim of this study was to assess the efficacy of mepolizumab at a dose of 100 mg administered every 4 weeks in preventing relapses of ICEP and its impact on the clinical outcomes. Methods: This retrospective clinical observational study used real-world data to assess the impact of mepolizumab on patients diagnosed with ICEP accompanied by severe asthma. Demographic information and clinical characteristics were extracted from medical records. The study examined the effect of mepolizumab on the annual relapse rate, OCS dose, eosinophil count, and respiratory function parameters. Results: All patients included in the study, with a median (range) follow-up period of 19 months (4-40 months), the annual relapse rate decreased from 0.33 to 0 after the initiation mepolizumab. In addition, the maintenance OCS dose, expressed in methylprednisolone equivalents, declined from 4 mg/day to 0 mg/day. A reduction in the blood eosinophil count was observed, alongside a partial improvement in respiratory function test results among the patients. Conclusion: A dose regimen of 100 mg of mepolizumab administered every 4 weeks emerges as a promising and well-tolerated therapeutic approach for averting relapses of ICEP.

SARS-CoV-2 clearance in term of Cycle Threshold (Ct) during first two waves of COVID-19 in Pakistan: a phenomenon of delayed viral clearance post-corticosteroid treatment.

SARS-CoV-2 is recently emerged virus, which caused millions of deaths, all over the world. To tackle COVID-19 pandemic, there is an utmost need for in-depth analysis of viral replication. We aimed to examine viral load in SARS-CoV-2 patients during first two waves of COVID-19 in Pakistan. 225,615 suspected subjects from 75 different regions of Pakistan were selected in the study. SARS-CoV-2 RNAs were detected via real time PCR. During first wave (period of June-July, 2020) of COVID-19 the prevalence of SARS-CoV-2 was 20.38%. However, during second wave (period of November-December, 2020) of COVID-19, the rate of prevalence was 9.41%. During first wave of COVID-19 96.31% of participants remained PCR positive for 14 to 21 days, 3.39% of subjects showed positive results for 22 to 35 days, while delayed Ct values were observed among 0.26% of participants for 36 to 49 days. However, during second wave of COVID-19 89.31% of the subjects exhibited symptoms and showed real-time PCR positive results for 14 to 21 days, 9.42% showed positive results for 22 to 35 days, while significantly delayed Ct value results were observed among 1.026% of participants for 36 to 63 days (3.95 times higher than first wave). In contrast to first wave of COVID-19, the factors that were different in second wave were neither viral (different strains) nor host (same population). But treatment factors changed significantly. As during second wave besides azithromycin, corticosteroid dexamethasone consumption was increased consequently causing delayed Ct value negativity. This suggests that corticosteroid treatment might be linked with delayed Ct value or viral clearance. This study is crucial for re-considering effective therapeutic options against COVID-19.

[Reversible cerebral vasoconstriction syndrome. Recurrence of thunderclap headaches after treatment with corticosteroids]. / Síndrome de vasoconstricción cerebral reversible. Recurrencia de cefaleas en trueno tras tratamiento con corticoides.

INTRODUCTION: Reversible cerebral vasoconstriction syndrome is a clinicoradiological entity with a self-limiting course that manifests with recurrent episodes of thunderclap headache, and is associated with certain triggers. Recurrence is very rare, and the pathophysiology is thought to be related to altered autoregulation of the cerebrovascular tone. We present a clinical case that raises questions about possible recurrences and triggers. CASE REPORT: A 44-year-old woman with a history of multiple sclerosis treated with interferon beta-1b who had four episodes of thunderclap headache while resting, after completing a course of corticosteroids due to a flare-up of optic neuritis. Three years earlier, the patient had presented several episodes of explosive-onset headache during a self-limited period of one month, only occurring during sexual intercourse. In the year prior to our assessment, she had suffered three thunderclap headaches with similar characteristics, but they were triggered only by intense physical exercise. She had not consulted a physician about these events. A cranial computed tomography scan was performed after the administration of contrast media and a cerebral arteriography, which were consistent with cerebral vasoconstriction syndrome, and its reversibility was confirmed three months later. CONCLUSIONS: Reversible cerebral vasoconstriction syndrome shares a phenotypic expression with primary exertion headaches. It is associated with drugs with vasoactive effects, including interferons, and corticosteroids are associated with a worse prognosis, and such their administration should be avoided.

TITLE: Síndrome de vasoconstricción cerebral reversible. Recurrencia de cefaleas en trueno tras tratamiento con corticoides.Introducción. El síndrome de vasoconstricción cerebral reversible es una entidad clinicorradiológica de curso autolimitado que se manifiesta con episodios de cefalea en trueno recurrentes y que se asocia a determinados desencadenantes. La recidiva es muy poco frecuente y la fisiopatología se cree que está en relación con la alteración de la autorregulación del tono vascular cerebral. Presentamos un caso clínico que plantea cuestiones sobre posibles recurrencias y desencadenantes. Caso clínico. Mujer de 44 años con antecedente de esclerosis múltiple en tratamiento con interferón beta-1b que consultó por cuatro episodios de cefalea en trueno en reposo, tras finalizar un ciclo de corticoides por un brote de neuritis óptica. Tres años antes, la paciente había presentado varios episodios de cefalea de inicio explosivo durante un período autolimitado de un mes, únicamente producidos en el contexto de relaciones sexuales. El año previo a nuestra valoración padeció en tres ocasiones cefalea en trueno de características similares, pero exclusivamente desencadenadas con el ejercicio físico intenso. No había consultado por estos eventos. Se realizó una tomografía computarizada craneal tras la administración de contraste y una arteriografía cerebral, que fueron compatibles con síndrome de vasoconstricción cerebral, y se confirmó su reversibilidad tres meses después. Conclusiones. El síndrome de vasoconstricción cerebral reversible comparte expresión fenotípica con el grupo de cefaleas primarias por esfuerzo físico. Se asocia a fármacos con efectos vasoactivos, entre los que se encuentran los interferones, y los corticoides se asocian a un peor pronóstico, por lo que es importante evitar su administración.

Systemic Corticosteroid as an Adjunct for Acute Respiratory Distress Syndrome in Non-Fatal Fresh Water Drowning: An Evidence-based Case Report.

BACKGROUND: Acute lung injury or acute respiratory distress syndrome (ARDS) is one of the most common complications of non-fatal drowning. Although respiratory societies' guidelines endorse the role of systemic corticosteroids in ARDS, the evidence for systemic corticosteroid use in ARDS due to non-fatal drowning is limited. METHODS: A search was conducted on Pubmed, OVID, and EuropePMC, assessing the clinical question using inclusion and exclusion criteria. The selected studies were critically appraised, and the results were summarized. RESULTS: A total of six retrospective studies were selected and assessed, all studies showed poor validity and a high risk of bias. Out of six studies, only four informed us of steroid administration's effect on outcomes. In two studies, mortality associated with corticosteroid administration seemed to be higher. On the contrary, one study found no mortality in the corticosteroid group, but 100% mortality was observed in the control group. In another study, steroid therapy seemed to not affect hospital length of stay or mechanical ventilation rates. CONCLUSION: Corticosteroid administration for non-fatal drowning and its impact on clinical outcomes remains equivocal. Routine administration of corticosteroids is not indicated and should be done on a case-by-case basis.

[Differential diagnosis and therapy of immune thrombocytopenia]. / Differenzialdiagnose und Therapie der Immunthrombozytopenie.

Immune thrombocytopenia is caused by autoantibodies against surface antigens on platelets. Since only about 50 % of cases will allow the identification of glycoprotein-specific antibodies, ITP remains a diagnosis of exclusion. Apart from EDTA-induced pseudo thrombocytopenia, other diseases like secondary thrombocytopenia due to medication, a large number of other disease and hereditary thrombocytopenias must be taken into account. The first-line therapy of ITP includes corticosteroids and intravenous immunoglobulins. The second line consists of thrombopoietin receptor agonists, rituximab, or splenectomy. For further lines of therapy, Fostamatinib and non-steroidal immunosuppressives are available.

Efficacy of corticosteroid therapy for oxygen-free coronavirus disease 2019-derived pneumonia.

Corticosteroid therapy for oxygen-free coronavirus disease 2019 (COVID-19) is not recommended due to its negative prognostic impact, but the efficacy of corticosteroids when limited to COVID-19 pneumonia is unclear. We aimed to evaluate the efficacy of corticosteroid monotherapy for patients with COVID-19 pneumonia without supplemental oxygen. We retrospectively reviewed patients with oxygen-free COVID-19 pneumonia at our institute between September 2020 and August 2021 and assessed the use of corticosteroids and the timing of initiation. We classified the patients into the following 2 groups: those who were initiated corticosteroids without developing respiratory failure (early steroid group) and those who were not (standard of care [SOC] group). We used inverse probability of treatment weighting (IPW) to balance between the groups. The primary outcome was the incidence of respiratory failure. A total of 144 patient records were reviewed; 63 patients were in the early steroid group and 81 patients were in the SOC group. Of all patients, 14 (22.2%) and 27 (33.3%) patients in the early steroid and SOC group, respectively, required supplemental oxygen (P = .192). After adjusted by the IPW method, 10 (16.0%) and 32 (40.1%) patients in the early steroid and SOC groups, respectively, required supplemental oxygen (P = .004). The logistic regression analysis indicated that early corticosteroid use was significantly associated with a decreased incidence of respiratory failure (odds ratio; 0.17, 95% confidence intervals; 0.06-0.46, P < .001). Corticosteroid monotherapy may suppress the development of exacerbation requiring oxygen supply in patients with oxygen-free COVID-19 pneumonia.

Recurrent steroid-responsive polyserositis of unclear aetiology: a possible post-COVID-19 phenomenon.

A previously healthy male patient presented with relapsing serous effusions affecting the pleural, pericardial and peritoneal membranes, along with thrombocytopaenia, following infection with COVID-19. An extensive workup was performed to rule out potential causes of polyserositis, including an infectious disease screen, autoantibody testing and imaging; however, no clear other cause was found. He exhibited a robust response to high-dose corticosteroid therapy but experienced several recurrences on tapering of treatment. His clinical course and treatment response were most suggestive of an autoimmune or autoinflammatory cause of polyserositis, though without confirmation of a specific underlying diagnosis. This report builds on existing literature on a possible link between COVID-19 and polyserositis.

Chondrotoxicity of Intra-Articular Injection Treatment: A Scoping Review.

The purpose of this scoping review was to identify possible chondrotoxic effects caused by drugs usually used for intra-articular injections. PubMed, Scopus, Web of Science and Cochrane were searched. Inclusion criteria required randomized controlled trials written in English that evaluate the toxic effect that damages the cartilage. The literature search resulted in 185 unique articles. 133 full-text articles were screened for inclusion, of which 65 were included. Corticosteroids, with the exception of triamcinolone, along with local anaesthetics, potentially excluding ropivacaine and liposomal bupivacaine, and nonsteroidal anti-inflammatory drugs, exhibited insufficient safety profiles to warrant casual use in clinical settings. Hyaluronic acid, on the other hand, appears to demonstrate safety while also mitigating risks associated with concurrent compounds, thereby facilitating therapeutic combinations. Additionally, there remains a paucity of data regarding platelet-rich plasma, necessitating further evaluation of its potential efficacy and safety. Overall, it seems that results are significantly influenced by the dosage and frequency of injections administered, observed in both human and animal studies.

Role of Doxofylline, Low Dose Theophylline, and Dexamethasone in Mice (BALB/C) Model of Corticosteroid Resistant Asthma: A Comparative Study.

OBJECTIVE: This study was designed to determine the comparative efficacy of Doxofylline (DOXO) compared to low-dose theophylline (LDT) in treating corticosteroid-resistant asthma. METHODS: This study was conducted on 56 adult BALB/C mice aged six to eight weeks old with an average weight of 20-25 g. They were divided into seven groups: control group, ovalbumin (OVA)+lipopolysaccharide (LPS) group, OVA+LPS+dexamethasone (DEXA) group, OVA+LPS+LDT group, OVA+LPS+ group, OVA+LPS+DEXA+LDT group, and OVA +LPS+DEXA+DOXO group. All mice were administered IP DOXO+DEXA. All the doses were administrated one day before the first challenge and lasted for five consecutive days after one hour of the OVA challenge until sacrificed. Lung biochemical parameters, including interleukin (IL)-2, IL-4, IL-8, IL-10, and IL-17 levels, were measured using enzyme-linked immunosorbent assay (ELISA). In addition, Histone deacetylase (HDAC) activity and lung histological analysis were also performed. Furthermore, the glucocorticoid receptor was measured by nexttec™. RESULTS: The OVA+LPS group exhibited significantly (p<0.05) elevated levels of interleukin (IL)-2, IL-4, IL-8, IL-10, and IL-17 compared to controls, indicative of airway inflammation. Moreover, OVA+LPS induction significantly (p<0.05) increased the levels of Interferon-gamma (IFN-γ), NF[Formula: see text]B, Tumor Necrosis Factor (TNFα), and Immunoglobulin E (IgE) parameters, indicating severe inflammation and immune response and successfully induced the disease model. Meanwhile, LDT and DOXO in conjunction with DEXA, further augmented HDAC2 activity compared to DEXA alone. Similarly, the administration of LDT increased the expression of GR by 64.5% (23.72±0.34), while DOXO increased the expression of GR by 94.10% (27.99±0.15), which restores it back to control. Furthermore, according to Hematoxylin and eosin (H&E) stained sections, the DOXO group exhibited a slight improvement in these histopathological features, suggesting a modest therapeutic effect. Masson's Trichrome staining showed a slightly improved patchy collagen deposition within alveolar spaces in intra-alveolar and interstitial inflammatory cell accumulation in DOXO group, and the combination of these drugs (DEXA+LDT group) improved collagen deposition moderately within alveolar spaces in intra-alveolar and interstitial inflammatory cell accumulation. Overall, treatment with DOXO, LDT alone, and with DEXA combination led to reductions in cytokine levels, with DOXO and LDT showing significant (p<0.05) efficacy to DEXA used alone, which showed non-significant (p>0.05) efficacy. CONCLUSIONS: Doxofylline and LDT were found to be effective therapeutic agents when used alone or in combination with Dexamethasone. However, randomized controlled trials are required to evaluate its further efficacy.
