ABSTRACT
Introduction: TBX1 haploinsufficiency is an inborn error of immunity with the phenotype of DiGeorge Syndrome. DiGeorge Syndrome has variable immunodeficiency associated with grade of thymic hypoplasia ranging from mild with no infections to severe requiring thymus implant. Enterovirus is an example of an opportunistic infection that can be fatal in these patients. Case Presentation: A 1 year old girl with TBX1 haploinsufficiency complicated by Tetralogy of Fallot, pulmonary atresia, high arched palate, and vesicovaginal fistula presented for elective cardiac repair surgery from another country due to failure to thrive and cyanosis. She had no prior infectious history but was on sulfamethoxazole-trimethoprim for prophylaxis. She was asymptomatic with a negative COVID test but no other infectious studies performed. Immediately postoperatively, she was febrile and nasal respiratory viral panel was positive for rhinovirus/enterovirus with increased procalcitonin and leukocytosis with left shift. She decompensated with multi-organ failure and cardiac arrest on postoperative day two. She was cannulated to veno-arterial extracorporeal membrane oxygenation (ECMO). Pre-operatively, she had a normal absolute lymphocyte count. No thymus tissue was observed in surgery. She had profound CD3 lymphopenia to 130 cells/cmm when critically ill. Enteroviral meningitis was suspected as no infectious, cardiac, or other pathology could be identified causing decompensation. Enteroviral serum polymerase chain reaction (PCR) test was negative while lumbar puncture deferred due to clinical status. She was treated with immunoglobulin. Offlabel investigational drug pocapavir was considered but deferred to patient's irreversible neurological status. The patient was disconnected from ECMO and expired. Discussion(s): Though we cannot confirm that this patient had enteroviral meningitis, invasive enteroviral infections are associated with elevated transaminases, coagulopathy, and seizures all present in our patient. There has also been reported negative serum enteroviral PCR but positive CSF enteroviral PCR in an immunodeficient patient. Additionally, this case highlights the importance of immunologic evaluation in patients with DiGeorge Syndrome and questions if asymptomatic viral screening for viruses like enterovirus should be considered pre-operatively in patients with inborn errors of immunity. This case highlights potential treatment options for invasive enteroviral infections in patients with inborn errors of immunity: high dose immunoglobulin, fluoxetine, and pocapavir.Copyright © 2023 Elsevier Inc.
ABSTRACT
SARS-CoV-2 which first was observed in Wuhan region, China in December 2019 is affected many organs, such as central nervous system. We describe a case of a 57-year-old male patient, in hospital with the loss of consciousness, in the form of lack of verbal and visual communication. He got a seizure attack for about 3 minutes in the form of generalized tonic-clonic seizure (GTS) and admitted to the neurological department and was intubated. Since, the patient was not aware, awake, did not obey, corneal reflexes test was positive and his pupils were isochoric and reactive therefore, the primary diagnosis was cerebrovascular accident (CVA). On the second day after admission, although the brain computed tomography (CT) did not show brain lesion, but chest X-ray (CXR) revealed lung involvement. In addition, on third day the RT-PCR test for coronavirus RNA in and the cerebrospinal fluid and nasopharyngeal swap done and the result was positive for both of them. Therefore, treatment for the covid-19 was started. Result(s): Since, the treatment for the covid-19 was started with Atazanavir, Clindamycin and ceftriaxone, ten days after hospitalization, the lung involvement and general condition of patient got better and after two weeks he was released from the hospital. Conclusion(s): GTS should be considered as a neurological outcome of COVID-19 and medications against the coronavirus, such as Atazanavir, Clindamycin and ceftriaxone can recover the neurological deficits in these patients.Copyright© 2020, TMU Press.
ABSTRACT
Objective To explore the application of ultrasound-guided arterial line placement in severe patients with COVID-19. Methods From February to April 2020, we retrospectively collected and analyzed the clinical data of critical patients with COVID-19 with an indwelling peripheral arterial catheter treated by the medical team of Peking Union Medical College Hospital. Patients with ultrasound-guided peripheral arterial catheterization were taken as the study group, while patients whose arterial catheter was placed by traditional palpation were taken as the control group. The puncture condition and complication rate were compared between the two groups. Results A total of 60 severe patients with COVID-19 who met the inclusion and exclusion criteria were enrolled in this study. There were 30 cases in the study group and 30 cases in the control group. In the study group, the success rate of the first catheterization of the peripheral artery (63.3% vs. 26.7%) and the total puncture success rate [(79.43+/- 25.79)% vs. (53.07+/-30.21)%] were higher than those in the control group (all P < 0.05), the puncture times(1.43+/-0.56 vs. 2.50+/-1.28) were less than those of the control group (P < 0.05). The rates of 24-hour disuse (6.7% vs. 30.0%), local hematoma (10.0% vs. 36.7%), occlusion, and tortuous (3.3% vs. 40.0%) in the study group were lower than those in the control group (all P < 0.05). Conclusion Under the three-level protection, ultrasound-guided arterial catheter placement for severe patients with COVID-19 can improve the success rate of catheter placement, reduce puncture times, and reduce the incidence of complications.Copyright © 2021, Peking Union Medical College Hospital.

ABSTRACT
Background: To assess the safety, tolerability, and pharmacokinetic (PK) profile in humans of the novel inhaled epithelial sodium channel blocker ETD001. Method(s): Inhaled ETD001 or placebo, delivered via nebulizer, have been administered in a 3:1 ratio to 96 healthy subjects in a blinded, first-inhuman clinical trial (ClinicalTrials.gov Identifier: NCT04926701). The study consisted of two parts. Part A evaluated single ascending doses (SADs) up to 10.8 mg, and Part B evaluated multiple ascending doses (MADs) up to 3.1 mg once daily (QD) for 7 days and 4.65 mg twice daily (BID) for 14 days. Safety was assessed by monitoring for adverse events (AEs), laboratory safety tests (including blood potassium monitoring), vital signs, 12-lead electrocardiogram (ECG), and spirometry. Systemic exposurewas assessed using serial pharmacokinetic blood draws. Result(s): Therewere no serious AEs. Twenty-four subjects reported 38 AEs, all of mild to moderate intensity and all resolved. There were no clinically relevant changes in laboratory safety tests, vital signs, ECGs, or spirometry measurements. All blood potassium assessments were within normal range at all doses. Three subjects withdrew in Part B;all withdrawals were considered unrelated to study drug: one on day 6 from the 3.1-mg QD cohort for personal reasons, one after the first dose of the 3.1-mg BID cohort because of vasovagal syncope at time of venipuncture triggering atrial fibrillation that spontaneously resolved, and one on Day 4 of the 3.1- mg BID cohort because of a positive COVID-19 test. Pharmacokinetic parameters were approximately dose proportional in Part A, with peak concentrations 1 to 2 hours after dose and exposure out to 12 to 24 hours at all doses, indicating good lung retention. Part B plasma concentrations displayed dose-independent kinetics and showed minimal accumulation, with a mean of 1.11-fold observed over 14 days. Conclusion(s): ETD001 was well tolerated at single doses up to 10.8 mg and multiple doses of 3.1 mg QD for 7 days and 4.65 mg BID for 14 days. The wide safety margin is predicted to enable doses capable of durable target engagement in the lung, which are expected to enhance mucociliary clearance in people with cystic fibrosis.Copyright © 2022, European Cystic Fibrosis Society.

ABSTRACT
Purpose of study COVID-19 primarily affects the respiratory system from flu-like syndrome to acute hypoxic respiratory failure. Neurological manifestations are uncommon and can result in serious complications. We report a unique case of sudden onset of rapidly progressive encephalopathy in the setting of COVID-19. Methods used Reviewed the manifestations, clinical course, and outcome for a patient presenting with altered mental status secondary to COVID-19. Summary of results A 48-year-old with no significant past medical history presented to the emergency department complaining of severe headache for four days. His vital signs on presentation showed a blood pressure of 154/90, pulse of 114 bpm, temperature of 99.6 degreeF, and oxygen saturation of 97% on room air. Physical exam was unremarkable. Lab work showed elevated D-dimer 8,500 ng/L, Elevated ESR:42, LDH:340 and Ferritin:692. White blood count: 7.59 uL, Platelets 50 x 103 uL. Computer tomography angiography (CTA) of the chest showed bilateral multifocal pneumonia. CT Head was performed and was negative for an acute hemorrhage, hydrocephalus or territorial infarcts. Patient spiked a fever shortly after admission 103degreeF. Patient was started on Ceftriaxone and Azithromycin. Blood and urine cultures were positive for Klebsiella pneumonia. Patient was re-evaluated in the morning and was found altered with associated neck stiffness. Antibiotics were switched to cover for suspected meningitis. Neurology was consulted and recommended lumbar puncture. Within a few hours, the patient's mental status deteriorated and was found to be hypertensive with a blood pressure of 220/110. Repeat CT Head was negative. The patient was tested and found to be positive for COVID-19. Patient further decompensated within a few hours and became unresponsive, pulseless. ACLS was performed and the patient was transferred to the intensive care unit. Conclusions This case report highlights the heterogenous presentation in patients with COVID-19 and the importance of recognizing a new onset, severe headache as the only initial presentation. Headaches in some cases may precede the respiratory symptoms or may be the only manifestations in COVID-19 patients and it is crucial to be aware of the neurological complications and the rapid decompensation these patients may undergo if not recognized early.
ABSTRACT
Case Report: Cryptococcosis is an opportunistic infection caused by the encapsulated yeast Cryptococcus, with C. neoformans and C. gattii being the most common species to cause human disease. Immunocompromised individuals are predisposed to infections with C. neoformans, which has known predilection to CNS and pulmonary lymph nodes. We present a unique case of disseminated cryptococcosis in the setting of end-stage renal disease (ESRD), cirrhosis, tumor necrosis factor inhibitor use and steroid use for COVID19. Method(s): A single-patient case report was conducted after IRB approval. Case Presentation: A 55-year-old woman with uncontrolled diabetes, lupus, rheumatoid arthritis on adalimumab, hepatitis C status post boceprevir, cirrhosis, former IV drug use, and ESRD on hemodialysis via bovine arterial-venous fistula graft presented with worsening dyspnea, cough, and altered mental status. Three months prior, patient was admitted to an outside hospital for COVID19, complicated by pulmonary embolism status post anticoagulation therapy. Patient was treated with an unknown steroid regimen, which was continued by a second outside facility when symptoms failed to improve. Patient then presented to our facility 24 hours after discharge due to continued symptoms. On admission, patient was noted to have altered mentation and hypoxia with pulmonary edema on chest x-ray and was urgently hemodialyzed. Further work-up was obtained due to non-resolving symptoms, including blood and sputum cultures, cocci serology and QuantiFERON gold. CT chest revealed bilateral consolidations. Patient was started on antibiotics for presumed hospital-acquired pneumonia. During the hospital stay, preliminarily blood cultures grew yeast and patient was started on Micafungin. However, Micafungin was changed to Liposomal Amphotericin B as ovoid structures seen on gram stain could not confirm nor rule out cryptococcus. Subsequent bronchial wash and bronchoalveolar lavage cultures, as well as final blood cultures resulted Cryptococcus neoformans. Serum cryptococcus antigen returned reactive, titer 1:512. Antibiotics were discontinued and Isavuconazonium was started with Liposomal Amphotericin B. Due to recurrent headaches, lumbar puncture was obtained and revealed lymphocytic pleocytosis without cryptococcal antigenicity. Patient completed 14 days of Liposomal Amphotericin B and Isavuconazole with continuation of Isavuconazole upon discharge. Conclusion(s): Disseminated cryptococcosis in non-HIV patients is rare in the modern HIV era. Clinicians should be aware and include it in their differential of any patient with multiple risk factors for opportunistic infection. In patients with cirrhosis and ESRD, treatment is limited given altered pharmacokinetics. Studies have shown improved survival with the addition of Isavuconazole in patients with disseminated cryptococcosis with CNS involvement in the setting of chronic liver disease and ESRD.
ABSTRACT
Background: Hospitals are one of the primary resources for disease transmission, so many guidelines were published, and neuro-surgeons were advised to postpone elective spine surgeries during the COVID-19 pandemic. Objective(s): To avoid pulmonary complications and reduce the risk of spreading the virus and contracting the disease during the COVID-19 era, we operated a group of our patients under spinal anesthesia rather than general anesthesia. Method(s): We retrospectively analyzed all patients who underwent discectomy surgery for lumbar spinal disc herniation under SA between September 2020 and 2021. Result(s): Sixty-four patients diagnosed with lumbar disc herniation underwent lumbar discectomy with SA. All patients except three were male. The mean age was 44.52 +/- 7.95 years (28 to 64 years). The mean procedure time for SA was 10 minutes. The duration of the surgery was 40 to 90 minutes per each level of disc herniation. The mean blood loss was 350 cc (200 to 600 cc). The most common involved level was L4/L5 intervertebral disc (n = 40 patients;63.5%). The mean recovery time was 20 minutes. Only three patients requested more analgesics for relief of their pain postoperatively. All patients with discectomy were discharged a day after surgery, and in the case of fusion, two days after surgery. All the patients were followed up for six months, showing no recurrence symptoms, good pain relief, satisfaction with the surgery, and no bad memory of the surgery. Conclusion(s): Spinal anesthesia is a good alternative or even the main anesthesia route for patients with lumbar disc herniation. More studies are needed to elucidate the best candidate for SA in patients with lumbar pathology.Copyright © 2023, Author(s).
ABSTRACT
BACKGROUND: Since the first reports in November 2019, coronavirus 2 has represented a priority health problem causing severe acute respiratory syndrome and other extrapulmonary manifestations, originating a pandemic with millions of deaths. Therefore, vaccines represent the most effective means of controlling the COVID-19 pandemic. Skin reactions to COVID-19 mRNA vaccines have been observed. The objective of this paper is to evaluate the morphology of the cutaneous manifestations and to carry out a review on the current recommendations for their management. CLINICAL CASE: Case 1: A 25-year-old male patient who presented a morbilliform rash after the first dose of the Pfizer vaccine against SARS-CoV-2, which remitted without sequelae at 24 hours. Case 2: A 65-year-old female patient with erythema at the puncture site 10 days after the first dose of the Modern vaccine against SARS-CoV-2 with complete remission on the 4th day after its onset. CONCLUSION(S): Some of the dermatological manifestations to the mRNA COVID-19 vaccines were identified as mimicking the SARS-CoV-2 infection itself. As the administration of vaccines increases, it is essential to recognize and understand their adverse effects.Copyright © 2022 Comunicaciones Cientificas Mexicanas S.A. de C.V.. All rights reserved.
ABSTRACT
Case Report: West Nile Virus (WNV) was first isolated from the West Nile district of Northern Uganda in 1937, but was first detected in the United States well over half a century later in 1999. The arthropod-borne virus has since persisted, with 2,401 cases reported to the CDC on average annually. The infection typically causes a nonspecific acute systemic febrile illness with occasional gastrointestinal and skin manifestations;however, in less than 1% of infected patients, it can cause severe and potentially fatal neuroinvasive disease, presenting as meningitis, encephalitis or acute flaccid paralysis. Immunosuppression is one of the risk factors associated with the development of neuroinvasive disease, and chemotherapy thus places patients at risk. Uterine leiomyosarcoma is a rare gynecological malignancy. Palliative chemotherapy is common in late stage disease, but may predispose patients to conditions that present as neutropenic fever, leading to a diagnostic conundrum. This is the first case report where patient with neutropenic fever was found to have West Nile neuroinvasive disease, so it is important to include West Nile disease in the differential diagnosis. Case Description: This is a case of a 45-year-old female with history of diabetes, hypothyroidism and recently diagnosed uterine leiomyosarcoma status post tumor debulking with metastasis on palliative chemotherapy with gemcitabine that presented to the Emergency Room for a fever of 103.8 degrees Fahrenheit. Given the history of advanced leiomyosarcoma, the patient was admitted for neutropenic fever with an absolute neutrophil count of 1000. During the hospitalization, the patient became acutely altered and confused. CT head without contrast and lumbar puncture were performed. Due to clinical suspicion of meningitis, she was started on broad spectrum antibiotics. Lumbar puncture revealed leukocytosis of 168 with lymphocytic predominance and elevated protein level in the cerebrospinal fluid, therefore acyclovir was started due to high suspicion of viral meningoencephalitis. An EEG showed severe diffuse encephalopathy as the patient was persistently altered. A broad workup of infectious etiology was considered including HIV, syphilis, hepatitis A, B, C, COVID-19, adenovirus, pertussis, influenza, WNV, HHV6, coccidiomycosis, aspergillus, and tuberculosis. Patient was ultimately found to have elevated IgM and IgG titers for West Nile Virus. Discussion(s): It is important to consider a broad spectrum of diagnosis in patients with metastatic carcinoma presenting with new-onset fever and acute encephalopathy. This includes working up for other causes of altered mental status including cardiac, neurologic, psychiatric, endocrine, metabolic, electrolyte, drug, and infectious etiology. While uncommon in the healthy population, WNV encephalitis should be on the radar for any patient who is immunocompromised or on immunosuppressive therapy, especially those who present with a neutropenic fever.
ABSTRACT
Case Report: This is a 50-year-old man that presented to the ED complaining of generalized weakness and acute loss of ability to ambulate which has been progressing for a month. Patient began having left arm and leg weakness, which started in his fingertips of his left upper extremity and soon moved proximally to upper left arm. Symptoms then progressed to right upper and lower arms. Symptoms further continued to progress making the patient bedridden. On presentation, CT head showed a C1/C2 subluxation possibly chronic without significant focal soft tissue swelling. CT cervical spine showed C1-C2 subluxation, possibly chronic. MRI of brain was unremarkable pre and postcontrast without focal findings or abnormal enhancement and showed redemonstration of the C1-C2 subluxation as described on CT scan. MRI of cervical spine showed at the level of C1 there is spinal canal stenosis. However, there is no direct pressure upon the cord/medulla. Upon evaluation, patient had significant motor weakness and required maximal assistance for movement. Patient was moreover noted to have flaccidity of muscles associated with weakness with no bulbar weakness. Patient had no difficulty in breathing or with speech. A lumbar tap was performed which showed elevated protein, WBC, and glucose. Upon further investigation, patient stated that he received his (3rd dose) of the Moderna Vaccine for Covid-19 about a month before the onset of symptoms and felt fine. Two weeks later, he began experiencing subjective fevers, diarrhea, abdominal pain, and fatigue that lasted for a week and then self-resolved. Approximately another two weeks later is when patient began noticing his neurological symptoms. Possible Guillain-Barre Syndrome post Campylobacter Jejuni (C. Jejuni) infection vs. post Covid-19 vaccine induced GBS was suspected at this point and patient was started on Intravenous Immunoglobulin (IVIG). Stool cultures were collected for C.Jejuni which came back negative. Gastrointestinal Pathogen Panel PCR Feces also came back negative. Patient was discharged to a rehab center and planned to receive another round of IVIG for 5 days. Conclusion(s): Guillain Barre Syndrome (GBS) is a rare immune-mediated neurological disorder affecting peripheral nerves and nerve roots, that presents as acute sensorimotor neuropathy starting with distal paresthesia that progresses to weakness of legs and arms, noteably, flaccid paralysis. GBS has several triggers namely infections such as C. jejuni, cytomegalovirus, M. pneumoniae, Epstien-Barr virus and Zika virus. There has also been several case reports and studies that have shown increased incidence of GBS vaccines such as influenza vaccine. Furthermore, there has been several studies that have linked GBS to COVID-19 vaccine. With COVID-19 cases continuing to persist, and increasing advocacy for vaccination against the disease, GBS should be considered as very rare but possible side effect of the vaccine.
ABSTRACT
Background: Severe acute respiratory syndrome coronavirus 2 (SARSCoV2) has been associated with several neuro-ophthalmic manifestations. We report a case of bilateral longitudinally extensive optic perineuritis suspected due to SARSCoV2. Case Presentation: A 32-year-old woman developed headaches, photophobia, pulsatile tinnitus, and blurred vision 8 d after having a positive SARS-CoV-2 qualitative polymerase chain reaction (PCR) testing for coronavirus disease 2019 (COVID-19). She was diagnosed with and treated for idiopathic intracranial hypertension (IIH) elsewhere. Repeat evaluation at our institution showed a poor visual acuity in both eyes with Frisen grade II papilledema and cotton wool spots on fundoscopic examination. Orbital magnetic resonance imaging (MRI) showed bilateral longitudinally extensive optic nerve sheath enhancement. Repeat lumbar puncture revealed an elevated cerebrospinal fluid (CSF) opening pressure and protein, a finding that is incompatible with the diagnosis of IIH. Myelin oligodendrocyte glycoprotein, aquaporin-4 (AQP4)-IgG antibodies, and other serological tests for optic neuritis were unremarkable. Her visual acuity partially improved after corticosteroids. With the growing association of demyelinating disorders and COVID-19, unremarkable serological workup, and temporal relation of the patient's symptoms to the infection, we believe that her diagnosis is SARS-CoV-2 associated bilateral optic neuritis. Conclusion(s): There is a growing association between demyelinating disorders and COVID-19 and COVID-19 vaccination, and it is essential to recognize CSF abnormalities that are incompatible with a diagnosis of IIH, such as increased protein in our case, and may lead to an incorrect diagnosis.Copyright © 2023 The Authors.

ABSTRACT
Since the introduction of COVID-19 vaccine, various adverse events have been reported including injection site pain, fatigue, headaches, and myocarditis. Cranial neuropathies and optic neuritis, have been also rarely reported, however, the significance of these autoimmune manifestations after the administration of COVID-19 vaccine remain controversial. In this report we present a case of myocarditis and bilateral optic neuritis that occurred in a young healthy male patient after the administration of first dose of mRNA-1273 vaccine (Moderna).Copyright © 2022 The Author(s)
ABSTRACT
Serotonin syndrome associated with clozapine withdrawal and concurrent selective serotonin reuptake inhibitor (SSRI) use has previously been reported. A 56-year-old female with schizophrenia was admitted for pyrexia, rigidity, and altered mental state after her second dose of clozapine restart. She had discontinued her long-term clozapine 2 weeks prior. She developed ventilatory failure, reduced consciousness, eye deviation, and worsening rigidity, requiring ICU support. Examination showed a right upper motor neurone syndrome with absent ankle reflexes. She had raised inflammatory markers and creatine kinase. Serum neuropathy, encephalitis screen, and COVID PCR were negative. Respiratory investigations were unfruitful. MRI head and spine did not show brain or cord signal change to correlate to signs. Lumbar puncture showed a quiet CSF, negative culture, viral PCR, and encephalitis antibodies. EEG showed bihemispheric background slowing. Despite clinical improvement, repeat examination showed persistent signs. She was diagnosed with serotonin syndrome after developing a bilateral tremor. Treatment with cyproheptadine correlated with an improvement in her signs, cognitive state, and EEG. Serotonin syndrome can present with reversible neuromuscular signs. With clozapine withdrawal, it can require a prolonged time course of recovery in contrast with classical serotonin syndrome. Cyprohepta- dine can cause agranulocytosis and this delays clozapine restart.
ABSTRACT
Background: In the context of the COVID-19 pandemic it is very important to achieve collective immunity. Allergic reactions to vaccines are rare -up to 30 per 100 000, but 4-8 may have anaphylaxis. The aim of this study was to develop safe COVID-19 vaccination algorithm for patients with allergic diseases (AD). Method(s): Patients with the history of AD were invited for vacination to the Regional Allergy Center in Dnipro (Ukraine). Before vaccination all patients underwent: serum tryptase, whole blood count (WBC), D-dimer, blood biochemistry, electrocardiogram (ECG) and spirometry (for patients with asthma (A) only). 126 patients with AD 19-85 (53.2+/-1.5) years old (50, 39.68% men) were included into the study. 25.39% of them had seasonal allergic rhinitis (SAR);15.07% -A;10.32% -A+ SAR;35.71% -urticaria;11.11% -drug allergy;2.38% -history of anaphylaxis. Result(s): There were not any clinically significant changes found in WBC, blood biochemistry and ECG. At the same time in 4 patients (3.2%) high tryptase level was detected. Mastocytosis was diagnosed by sternal puncture in 3 of them. During 12 weeks they were treated by monoclonal antibodies and after that vaccinated with two doses of mRNA vaccine without adverse reactions. For 1 patient with high tryptase level and a history of 3 anaphylaxis with hospitalization vacination was postponed. 1 patient had elevated D-dimer (PTA was diagnosed by CT) -vaccination was temporarily delayed. In 10 patients uncontrolled A with FEV1 below 70% (36-65%) was found. After the correction of basic therapy, within 2 weeks vaccination was carried out. All patients were given a 4-fold dose of desloratadine 30 minutes before vaccination. Conclusion(s): 1. AD are not a contraindication for vacciantion against COVID-19. 2. Before vacciantion all patients with a history of AD should be examined by an allergist. 3. For patients with severe AD level of serum tryptase should be detected before vacciantion. 4. Patients with AD should be vaccinated in an allergy center with premedication of H1-blocker in a 4-fold dose.
ABSTRACT
Background The incidence of severe bacterial infections (SBIs) in infants aged ≤90 days is thought to have decreased because of widespread vaccination programs. However, relevant epidemiological data in Japan are scarce. Materials and methods This observational, single-center study investigated the epidemiology of fever in infants aged ≤90 days. SBI was defined as the presence of meningitis, urinary tract infections (UTIs), or bacteremia. Invasive bacterial infection (IBI) was defined as the presence of meningitis, bacteremic UTI, or bacteremia. We determined the incidence of UTIs, bacteremia, meningitis, SBIs, and IBIs in the following three age groups: 0-28, 29-60, and 61-90 days. We subsequently calculated the relative incidence for the groups aged 29-60 and 61-90 days, using the group aged 0-28 days as the reference group. Results Herein, 58, 124, and 166 infants were included in the 0-28 days, 29-60 days, and 61-90 days age groups, respectively. Of the total number of patients, 15.5%, 8.9%, and 16.9% in the 0-28 days, 29-60 days, and 61-90 days age groups, respectively, were diagnosed with SBI. The relative incidences were 1 for the 0-28 days group (reference group), 0.67 for the 29-60 days group (95% confidence interval [CI], 0.39-1.15), and 1.08 for the 61-90 days group (95% CI, 0.58-2.00). Of the total number of patients, 10.3%, 3.2%, and 0.6% in the 0-28 days, 29-60 days, and 61-90 days age groups, respectively, were diagnosed with IBI. Relative incidences were 1 (reference group), 0.50 (95% CI, 0.29-0.88), and 0.28 (95% CI, 0.19-0.41) for the 0-28 days, 29-60 days, and 61-90 days age groups, respectively. All cases of IBI were caused by Group B streptococcus (GBS), except for two cases of bacteremia, which were caused by Haemophilus influenzae. Conclusion The incidence of SBI was similar in the 0-28 days and 61-90 days age groups. However, the incidence of IBI decreased with increasing age. The incidence of UTIs was highest in the 61-90 days age group, and that of meningitis and bacteremia decreased with increasing age.
ABSTRACT
Since December 2019 the world has been dealing with a severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) pandemic. The first SARS-CoV-2 vaccine was made available in Europe at the end of 2020. 202 volunteers from the vicinity of the University of Applied Sciences Wiener Neustadt took part in this study;their IgG levels recognizing the RBD of SARS-CoV-2 were determined. The aim was to evaluate the SARS-CoV-2 titer levels of vaccinated, recovered and vaccinated plus recovered persons. We could show that there is a significant difference in the antibody levels of vaccinated, vaccinated plus recovered and only recovered probands. Additionally, the highest antibody levels were found in triple vaccinated persons. Furthermore, the Moderna vaccine seems to have a higher immune response.Copyright © 2022
ABSTRACT
We present a rare case of meningoradiculitis occurring after mRNA COVID-19 vaccination. This patient, with a history of inflammatory arthritis following rubella vaccination, presented to the emergency department 4 days after her vaccination with both central and radicular nervous system symptoms. Symptoms included pain, sensory and motor deficits in L5 roots distribution, along with signs of central irritation, such as headache, difficulty concentrating and a Babinski sign. MRI showed bilateral L5 nerve roots enhancement. Lumbar puncture showed elevated protein and IgG, and relevant serologies excluded common causes. Prednisone and physical therapy helped the patient to achieve near complete recovery nine weeks after presentation. We concluded that this patient presented meningoradiculitis probably secondary to her vaccination in a context of possible overactive immune system. While such presentations might be rare, and do not constitute a general reason to abstain from vaccination, they must be well recognized and treated.Copyright © 2022
ABSTRACT
Background: There have been reports of demyelinating syndromes in association with COVID-19 and to a much lesser extent COVID 19 vaccines. The association between demyelination and vaccines, in general, remains controversial. We review a presentation of fulminant demyelination, and discuss antecedent COVID-19 vaccination, the formulation of a broader differential diagnosis and ultimately the pathologic diagnosis. Case presentation: An 80-year-old woman presented with seizure, encephalopathy, quadriparesis and ultimately expired. She received a SARS-CoV-2 vaccine one day prior. Imaging revealed contrast enhancing cerebral lesions, longitudinally extensive transverse myelitis. CSF was markedly inflammatory. Pathologic examination of the CNS lesions revealed demyelination and inflammation beyond white matter, not restricted to a perivenular distribution. Conclusion(s): This case depicts a seemingly fulminant course of a diffuse demyelinating syndrome characterized clinicopathologically as Marburg's variant of multiple sclerosis. There are several unique aspects of this case including the extremely rapid course, the unusual evolution of CSF abnormalities, with hypoglycorrhachia and markedly elevated protein. The proximity to vaccination is a pertinent association to document, though we cannot unequivocally prove causation.Copyright © 2022 The Authors
