Evaluation of patients with antiphospholipid syndrome subsequently COVID-19 vaccinations: A retrospective cohort study.

The aim of this study is to evaluate development of side effects, thrombotic or obstetric complications in our antiphospholipid syndrome (APS) patient group, after vaccination against coronavirus disease 2019 (COVID-19). A cohort was formed from patients who have previously been followed up with a diagnosis of APS. The patients of the cohort were evaluated retrospectively to find out if they were vaccinated with CoronaVac and/or BNT162b2 vaccines which are being used in our country. To evaluate the side effects seen after the vaccination, the information was collected by the patients in their outpatient appointments or making a phone call. Thirty-five APS patients who had received at least 1 dose of any of the COVID-19 vaccines were included in the study. Median (min-max) number of vaccine doses per patient was 2 (1-3). Eleven patients had a booster dose after primary vaccination. Twenty patients were ever vaccinated with BNT162b2 and 18 with CoronaVac. Among BNT162b2 recipients, 9 (45.0%) and among CoronaVac recipients 15 (42.9%) reported an adverse event after a vaccine administration. The most common adverse events were myalgia and malaise after any dose of both vaccines. No vaccine-related new thrombotic events or APS flares were observed. Our results were comparable with those reported in the literature. Comprehensive large-scale studies are needed for more accurate results on the evaluation of side effects after COVID-19 vaccination in APS patients.

Effects of COVID-19 on axial spondyloarthritis disease flare

Aims: Rheumatological disease flares may occur after many infections. However, our knowledge of the post-Coronavirus disease-2019 (COVID-19) axial spondyloarthritis (SpA) flares and related factors is limited. Methods: We retrospectively assessed the axial SpA patients who had COVID-19. Demographic and clinical data were collected from the medical records. The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) was applied via telephone for pre- and post-COVID-19 SpA symptoms. An increase of ≥2 points in the BASDAI score or any new extra-articular manifestations were defined as SpA flares and SpA patients were grouped as flares and noflare. Factors predicting SpA flare were also analyzed. Results: A total of 48 axial SpA patients were included in the study [age, mean±standard deviation (SD): 42.3±8.6 years;male: 65%]. Post-COVID-19 SpA flare was identified in 19 patients (40%), and new extra-articular manifestations were recorded in 6 patients (13%). Although the diagnosis of inflammatory bowel disease was more common in the flare group, the difference was not significant compared with that of the no-flare group. Other features of SpA and COVID-19 disease severity were similar between the flare and no-flare groups. In the flare group, the frequency of back pain (84% vs. 62%, p=0.091) and diarrhea (53% vs. 28%, p=0.080), and headache (84% vs. 52%, p=0.021) were higher than the no-flare group. No risk factor for a post-COVID-19 SpA flare could be identified. Conclusions: Post-COVID-19 flare was common in the axial SpA, and even new extra-articular manifestations could be reported. Although some clinical manifestations of COVID-19 were more common in patients with a flare, any predictive factor could not be identified among the study variables. [ FROM AUTHOR]

Safety and immunogenicity of inactive vaccines as booster doses for COVID-19 in Türkiye: A randomized trial.

Protective neutralizing antibody titers reduce in time after COVID-19 vaccinations, as in individuals who have had COVID-19. This study aimed to evaluate the safety and immunogenicity of CoronaVac and TURKOVAC vaccines used as a booster dose after CoronaVac primary vaccination. This double-blind, randomized, controlled, phase II, multicenter study included healthy male and female adults (18-60 years) who were vaccinated with two doses of CoronaVac vaccine and did not exceed the duration of at least 90 days and a maximum of 270 days from the second dose of vaccination. Among 236 eligible volunteers, 222 were recruited for randomization between July 12, 2021 and September 10, 2021; 108 and 114 were randomized to the TURKOVAC and CoronaVac arms, respectively. The primary endpoint was adverse events (AEs) (ClinicalTrials.gov; Identifier: NCT04979949). On day 28, at the neutralizing antibody threshold of 1/6, the positivity rate reached 100% from 46.2% to 98.2% from 52.6% in the TURKOVAC and CoronaVac arms, respectively, against the Wuhan variant and the positivity rate reached 80.6% from 8.7% in the TURKOVAC arm vs. 71.9% from 14.0% in the CoronaVac arm against the Delta variant. IgG spike antibody positivity rate increased from 57.3% to 98.1% and from 57.9% to 97.4% in the TURKOVAC and CoronaVac arms, respectively. The TURKOVAC and CoronaVac arms were comparable regarding the frequency of overall AEs. Both vaccines administered as booster yielded higher antibody titers with acceptable safety profiles.

What is the context? The timing of the primary and booster doses for each vaccine differs.We aimed to evaluate the safety and immunogenicity of CoronaVac and TURKOVAC vaccines used as homologous booster dose after CoronaVac primary vaccination.What is new? The neutralizing antibody titers against the Wuhan variant decreased below 1/6- the seropositivity threshold value- in more than 55% of the participants 4 months after administration of two doses of CoronaVac vaccine.Immunogenicity was re-stimulated and the neutralizing antibody titers increased rapidly and markedly with the administration of the CoronaVac or TURKOVAC as a booster dose 4 months after the second dose.While the increase in neutralizing antibodies against the Wuhan variant was similar with both CoronaVac and TURKOVAC, more antibodies developed against the Delta variant with TURKOVAC.What is the impact? With the Hybrid COV-RAPEL TR study, after the primary vaccination consisting of two doses of inactivated vaccine, antibody titers decreased in the long term; however, higher antibody titers are achieved than the primary vaccination after the booster dose administered after 4­6 month interval.Booster application with TURKOVAC provides antibodies at least as much as the CoronaVac booster dose, with an acceptable safety profile.

Comparison of anakinra and tocilizumab in management of severe COVID-19: a retrospective cohort study.

BACKGROUND: Studies regarding effectiveness of anakinra and tocilizumab treatments in coronavirus disease 2019 (COVID-19) have contradictory results. Furthermore, there is scarce comparative data regarding superiority of any agent. To further elucidate any superiority between these two agents, we retrospectively investigated and compared outcomes in hospitalized COVID-19 patients of our inpatient cohort who received anakinra or tocilizumab. METHODS: This study was designed as a single-center, retrospective, cross-sectional cohort study. Hospitalized patients with confirmed diagnosis of COVID-19 who had Brescia-COVID respiratory severity scale score ≥3 and hyperinflammation (defined as elevation of C reactive protein ≥50 g/L or ferritin ≥700 ng/mL) and received anakinra or tocilizumab in addition to standard care were enrolled in the study. Length of hospital stay after initiation of antiinflammatory treatment, need for mechanical ventilation, need for intensive care unit admission, mortality were set as primary outcomes and compared between tocilizumab and anakinra recipients after propensity score matching. RESULTS: One hundred and six patients were placed in each group after propensity score matching. In the anakinra group, relative risk reduction for intensive care unit admission was 50% when compared to the tocilizumab group and the number needed to treat to avert an intensive care unit admission was 3 (95% CI, 2-5). In terms of mortality, a 52% relative risk reduction was observed with anakinra treatment and the number needed to treat to avert an intensive care unit admission was 8 (95% CI, 4-50). Significantly more patients were observed to receive glucocorticoids in the anakinra group. DISCUSSION: Anakinra administration in severe COVID-19 patients was significantly associated with better survival and greater clinical improvement compared to the tocilizumab administration in our study. Increased rate of glucocorticoid use in the anakinra group might have contributed to better outcomes.

Clinical course of idiopathic inflammatory myopathies in COVID-19 pandemic: a single-center experience.

Aim: To evaluate the clinical course of idiopathic inflammatory myopathy (IIM) patients in COVID-19 pandemic, and to assess the COVID-19 outcomes in infected IIM patients. Materials & methods: In this study, 39 patients were evaluated retrospectively. Myositis disease activity, myositis damage index, depression, fatigue, active medical treatment, drug compliance and SARS-CoV-2 PCR test results in COVID-19 pandemic were collected. Results: Fourteen of these patients (35%) were detected to have a positive SARS-CoV-2 PCR test. The demographic and clinical characteristics, active medical treatment, disease activity, depression and fatigue of the patients who had undergone or not SARS-CoV-2 were similar. Conclusion: Our results have shown that although prevalence of COVID-19 seems to be increased in IIM patients under immunosuppressive treatment, hospitalization rates were lower and no intensive care unit admissions or deaths were observed.

Intravenous treatment adherence of patients with chronic inflammatory rheumatic diseases during the COVID-19 pandemic: experience of a single center.

Introduction: Patients with chronic inflammatory rheumatic diseases (CIRD) who receive intravenous therapy requiring hospitalization are likely to be more affected than those with receiving oral therapy during COVID-19 pandemic. We aimed to investigate the effect of the COVID-19 pandemic on adherence to treatment in patients with CIRD receiving intravenous treatments. Methods: We evaluated patients with CIRD who were treated with intravenous immunosuppressive therapy such as rituximab (RTX), cyclophosphamide (CTX), infliximab (IFX), tocilizumab (TCZ) and abatacept (ABA) in our inpatient rheumatology clinic. The patients' medical treatment compliance and clinical follow-up were evaluated. Treatment discontinuation was decided according to postponement of at least one dose and discontinuation of CIRD treatments. Demographics and clinical characteristics were compared between treatment-incompliant (TI) and treatment-compliant (TC) groups. Results: A total of 181 CIRD patients were enrolled. Rheumatoid arthritis was the most common disease requiring intravenous immunosuppressive treatment followed by axial spondyloarthritis and Behçet's disease. Joint involvement was the most common followed by lung and kidney involvements. Rituximab was the most widely used intravenous immunosuppressive treatment for the CIRD. 34% patients have postponed at least one dose of their intravenous CIRD treatment and 25% discontinued. Fear of COVID-19 and SARS-CoV-2 positivity were the most common reasons. The TI group had a longer disease duration and a higher frequency of inflammatory arthritis than the TC group (p=0.013 and p=0.044, respectively). Conclusions: Fear of COVID-19 and SARS-CoV-2 positivity seemed to be the major reasons for discontinuing/postponing intravenous treatments in CIRD patients. Patients with long disease duration and less systemic involvement may be more prone to discontinuing their treatments.

A single-center COVID-19 vaccine experience with CoronaVac and BNT162b2 in familial Mediterranean fever patients.

AIM: To determine frequency of adverse events and attacks related to vaccination in recipients of CoronaVac and BNT162b2 in familial Mediterranean fever (FMF) patients, and to search whether history of prior COVID-19 or a booster dose increases occurrence of adverse events/attacks. METHODS: FMF patients were surveyed for administration of any COVID-19 vaccine and vaccine-related adverse events or FMF attacks. Demographic, clinical, vaccine-related data, history of COVID-19 infection before or after vaccination, adherence to FMF treatment during vaccination were collected. RESULTS: A total of 161 vaccinated FMF patients were included. Ninety-three patients out of 161 had reported suffering from an adverse event/attack after a vaccine dose. There were 54.7% of BNT162b2 recipients who reported any adverse event after any vaccine dose in comparison to 29.9% of CoronaVac recipients (P < .001). There were 22.2% of BNT162b2 recipients who reported suffering from a FMF attack within 1 month after vaccination in comparison to 19.4% of CoronaVac recipients (P = .653). When patients with or without adverse event/attack were compared, no significant differences were observed in means of demographics, comorbid diseases, disease duration, total vaccine doses, or treatments adhered to for FMF. Rates of adverse events/attacks were similar between patients with and without prior COVID-19. In booster recipients, adverse events/attacks were most frequent after the booster dose. CONCLUSIONS: A considerable number of FMF patients suffered from vaccine-related adverse events/attacks, particularly with BNT162b2. No serious events or mortalities due to vaccination were detected. Demographics, clinical characteristics and prior history of vaccination did not significantly affect these results. We observed an increased rate of adverse events/attacks with booster dose administration.

Reducing length of hospital stay with colchicine.

INTRODUCTION: Colchicine is an ancient agent with well-known anti-inflammatory effects and commonly used in treatment of hyperinflammatory conditions. It has been argued that colchicine could be an appropriate treatment option in COVID-19 to control hyperinflammatory response. Here in this study, we aimed to investigate the impact of colchicine on outcomes of COVID-19 in our inpatient cohort. METHODOLOGY: In this retrospective cohort study, hospitalized COVID-19 patients were investigated. Demographics, comorbidities, COVID-19 symptoms, laboratory findings on admission and discharge, baseline and seventh day oxygenation status, rates of mortality, intensive care unit admission, administration of other anti-inflammatory treatments and length of hospital stay were compared between patients who received standard of care medications and who received colchicine additionally. RESULTS: Three hundred and thirty-six patients were included in the study (171 standard of care, 165 standard of care plus colchicine). The median length of hospital stay in colchicine group was significantly shorter. Rates of admission to intensive care unit, anti-inflammatory treatment administration and mortality did not differentiate between standard of care and colchicine groups. However, reduced rates of mortality and ICU admission were observed in patients who received colchicine with a dose of 1 mg/day when compared to patients who received 0.5 mg/day. CONCLUSIONS: Our study demonstrated that COVID-19 patients who received colchicine in addition to standard of care had shorter hospital stay. Our results further support the use of colchicine in treatment of COVID-19, particularly with a dose of 1 mg/day.

COVID-19 in patients with Behçet's disease: Outcomes and rate of Behçet's exacerbations in a retrospective cohort.

OBJECTIVES: The aim of this study is to investigate the outcomes of coronavirus disease 2019 (COVID-19) in our cohort of Behçet's disease (BD) patients and to reveal the rate of BD exacerbations due to COVID-19. METHODS: Patients who have been followed with a diagnosis of BD were retrospectively investigated for a positive severe acute respiratory syndrome-coronavirus 2 polymerized chain reaction (PCR) test. Data regarding demographics, clinical features and COVID-19 outcomes were collected from medical records for patients with a positive PCR. PCR-positive patients were reached via phone numbers, and 'Behçet's Disease Current Activity Form' (BDCAF) scores for pre- and post-COVID-19 BD symptoms were calculated. RESULTS: Out of a total 648 BD patients, 59 were detected to have a positive PCR test. Three of the 59 patients (5.0%) were found to be hospitalized, none of them was admitted to the ICU or died. An increasing trend in the frequency of comorbid diseases and older age was observed in hospitalized patients. 32.2% of BD patients suffered from exacerbation of at least one symptom related to BD. CONCLUSIONS: We observed no ICU admission or mortality with COVID-19 in our BD patient cohort. A substantial number of patients suffered from exacerbation of BD symptoms.

Can Anakinra and corticosteroid treatment be an effective option in pregnant women with severe Covid-19?

Anakinra, which is an Interleukin-1 (IL-1) receptor antagonist with the advancing disease process, has started to be considered as an alternative treatment for Covid-19 patients with cytokine storms. We evaluated the effect of corticosteroids and IL-1 receptor blockage with anakinra on pregnant patients with Covid-19 at high risk for respiratory distress, ongoing fever, deterioration in their general condition and consequently maternal and fetal complications. Fourteen pregnant women who received anakinra (median dosage: 400 mg) and corticosteroid (methylprednisolone-median dosage: 80 mg) treatment were evaluated retrospectively. Patients were assessed according to the World Health Organization (WHO) scale. The mortality rate of the cohort was 7.1%, the median hospitalization period of the patients was 15 days and 2 patients had premature births. Covid-19 was found to have a similar spectrum of symptoms in pregnant and non-pregnant women, such as dyspnea, cough and fever. Our study was the first to analyze the combined treatment of corticosteroid and anakinra in pregnant patients with pneumonia from Covid-19 based on the WHO scoring system. Due to the obscurity in the treatment process in pregnant patients, studies are ongoing on managing Covid-19 infection in these patients. We presume that the early use of anakinra and corticosteroid treatments in patients severely infected with Covid-19 may have positive effects on disease progression and survival.

Compliance to not only prone but also lateral and supine positioning improves outcome in hospitalised COVID-19 patients.

BACKGROUND: Positioning of the patient is a common strategy to increase oxygenation in the management of acute respiratory distress syndrome. The aim of this study is to demonstrate the effects of our positioning approach on disease outcomes in COVID-19 patients with respiratory failure, by comparing patients compliant to positioning and not. METHODS: COVID-19 patients who were admitted to our internal medicine inpatient clinic and developed hypoxaemia and underwent positioning during hospital stay were retrospectively investigated for compliance to positioning. Rates of mortality, intensive care unit admission, intubation, initiation of anti-inflammatory treatment and length of hospital stay were compared between patients with and without compliance to positioning. RESULTS: A total of 144 patients were enrolled in this study (97 compliant with positioning, 47 incompliant with positioning). Rates of ICU admission (7.2% vs 25.5%, p < .001), anti-inflammatory treatment initiation (68% vs 97.9%, p < .001) and length of hospital stay (5 (2-16) days vs 12 (3-20) days, p < .001) were significantly reduced in patients compliant with positioning. CONCLUSION: Prone or other positioning should be considered in patients with noninvasive oxygen support for the potential to reduce rates of intensive care unit admissions, airway interventions, anti-inflammatory treatment initiation and mortality.

A single center experience of intravenous immunoglobulin treatment in Covid-19.

BACKGROUND: Intravenous immunoglobulins (IVIg) have been used in management of severe Covid-19. Here in this study, we report our single-center experience regarding IVIg treatment in management of severe Covid-19. MATERIALS AND METHOD: Among hospitalized adult Covid-19 patients between April 1 and December 31, 2020, patients with confirmed diagnosis of Covid-19 who had Brescia-COVID respiratory severity scale score ≥ 3, hyperinflammation and received IVIg treatment in addition to standard of care were retrospectively investigated. We grouped IVIg recipients into three according to reasons for IVIg administration: Group 1 patients requiring anti-inflammatory treatment but complicated with secondary infection and/or sepsis , group 2 patients with Covid-19 related complications including progressive disease refractory to other anti-inflammatory agents, myocarditis, adult multisystem inflammatory syndrome, hemophagocytic lymphohystiocytosis like syndrome and group 3 patients with other complications non-specific to Covid-19. Mortality and clinical data was compared among groups. RESULTS: A total of 46 IVIg recipients were enrolled. Group 1 comprised 17 (36.9%), group 2 comprised 18 (39.1%) and group 3 comprised 11 (23.9%) patients. No significant differences in means of age, gender and comorbidities were observed among groups. Mortality was significantly lower in group 3 when compared to group 1 (64.7% vs 18.2%, p = 0.016) and close to significance when compared to group 2 (50% vs 18.2% p = 0.087). CONCLUSIONS: IVIg seemed to be used mostly in severe, refractory and complicated cases in our population. As a rescue agent in severe cases refractory to other anti-inflammatory strategies, 33.7% survival rate was observed with IVIg.

COVID-19 and eosinophilic granulomatosis with polyangiitis or COVID-19 mimicking eosinophilic granulomatosis with polyangiitis?

Coronavirus disease 2019 (COVID-19) and eosinophilic granulomatosis with polyangiitis (EGPA) share similarities in clinical, imaging findings and may present with respiratory distress. Differentiating a new-onset EGPA from COVID-19 during the current pandemic is a diagnostic challenge, particularly if other EGPA symptoms are overlooked. Here in this study we reviewed the literature regarding EGPA patients with COVID-19 and patients who diagnosed with EGPA or suffered an EGPA flare mimicking COVID-19. We conducted a literature survey in PUBMED database using meshed keywords "COVID-19" and "EGPA", "COVID-19" and "eosinophilic granulomatosis with polyangiitis", "COVID-19" and "Churg Strauss Syndrome", to reveal previously reported cases involving EGPA patients who had COVID-19 infection, patients who suspected to have COVID-19 but eventually diagnosed with EGPA and patients with a known diagnosis of EGPA who suffered a flare but a COVID-19 infection was suspected initially. A total of 11 cases (6 literature cases, 5 cases from our clinic) were included in our study. Seven (63.6%) of the cases were defined as COVID-19 mimicker and 4 (36.4%) were EGPA with COVID-19. All of the cases in EGPA with COVID-19 group had a history of asthma. All of them had a positive PCR result and ground-glass opacities in thorax CT. In COVID-19 mimicker group, six (85.7%) patients had a history of asthma and other EGPA features that were observed were eosinophilia in 6 (85.7%). Our study provided clues regarding the EGPA/COVID-19 diagnostic challenge which may be useful in the current pandemic. Since none of the findings in COVID-19 are disease-specific, other conditions like EGPA should not be overlooked particularly in PCR negative patients and clinical, laboratory and imaging findings should be interpreted carefully. Furthermore, we did not observe poor outcomes in EGPA patients who had COVID-19.

Evaluation of 17 patients with COVID-19 pneumonia treated with anakinra according to HScore, SOFA, MuLBSTA, and Brescia-COVID respiratory severity scale (BCRSS) scoring systems.

COVID-19 pandemic has been affecting the whole world by increasing morbidity and mortality rates day by day. Treatment algorithms have been attempted as parallel to the increasing experience with COVID-19. In the pathogenesis of this virus pro-inflammatory cytokine storm has been called to have the main role. The right timing should be made for treatments. We proposed IL- 1 blocking by anakinra in seventeen COVID-19 patients at high risk of worsening. Patients were assessed according to HScore, SOFA (Sequential Organ Failure Assessment Score = SOFA), MuLBSTA Score (multilobular infiltration, hypo-lymphocytosis, bacterial coinfection, smoking history, hyper-tension, and age), Brescia-COVID respiratory severity scale (BCRSS). In our study, the mortality rate was 17.6%. Consequently, 1 (5.9%) patient was receiving low-flow oxygen supply, 3 (17.6%) patients needed no longer oxygen supply and 10 (58.8%) patients were discharged from the hospital. According to the results of our study in the manner of general evaluation; we found that SOFA, MuLBSTA, and BCRSS scores were one step ahead according to HScore being insufficient to determine early phases of the disease. In our opinion, the prominent factors that emphasize the use of anakinra could be listed as comorbidity, risk, or presence of secondary infection, ongoing malignant disease. However, the other factors that enhance the use of anakinra in the situation of viremia also could be sorted as no response to full dose antivirals, antiviral side effects, or no success to antiviral treatment.

COVID-19 outcomes in patients with familial Mediterranean fever: a retrospective cohort study.

Aim of this study is to investigate the course of coronavirus disease 2019 (COVID-19), in our cohort of familial Mediterranean fever (FMF) patients in means of mortality, admission to hospital and/or intensive care unit and length of hospital stay.A retrospective cohort was formed from patients who have previously been followed with a diagnosis of FMF. Patients of this cohort were retrospectively evaluated for a positive severe acute respiratory syndrome-coronavirus 2 (SARS-CoV 2) polymerized chain reaction (PCR) test result and information regarding hospitalisation, intensive care unit admission and mortality were collected from medical records.Out of a total 496 FMF patients, 34 were detected to have a positive SARS-CoV 2 PCR test. Eighty-five point three percent of these patients were under colchicine treatment and 17.6% were under interleukin (IL)-1 inhibitor treatment. Eight of the 34 patients (23.9%) were found to be hospitalized, one of them was admitted to the intensive care unit and died thereafter (2.9%). An increasing trend in the frequency of comorbid diseases (presence of at least one comorbidity 64.7% in all patients vs 75.0% in hospitalized patients) and IL-1 inhibitor usage (17.6% in all patients vs 50.0% in hospitalized patients) was observed in hospitalized patients.Rates of comorbid diseases and IL-1 inhibitor use for FMF were observed to be increased in FMF patients hospitalized for COVID-19.
