Background The mechanism of cognitive dysfunction in systemic lupus erythematosus (SLE) is still not fully understood. Even though many SLE patients present some neurological dysfunction, including various deficits, neither a specific pattern nor structural changes associated with impairment have been established. Moreover, although prevalent and bothersome, deficits included the most recent diagnostic criteria. Purpose aim this study was to determine relationship between presence white...

Systemic sclerosis (SSc) is a connective tissue disease characterized by progressive fibrosis of the skin and internal organs, leading to their failure disturbances in morphology function blood vessels. The affects people different ways, identifying how difficulties limitations are related quality life may contribute designing helpful interventions. aim this study was identify factors associated with SSc.This cross-sectional conducted 11 rheumatic centres Poland. Patients diagnosed SSc were...

Long-term analyses of demographical and clinical characteristics COVID-19 patients can provide a better overview the course disease. They also help understand whether changes in infection symptomatology, disease severity, outcome occur over time. We aimed to analyze demographics, early symptoms infection, laboratory parameters, manifestation hospitalized during first 17 months pandemic Poland (March 2020–June 2021). The patients’ data (n = 5199) were extracted from national SARSTer database...

Tofacitinib is a newly approved small-molecule targeted synthetic disease-modifying antirheumatic drug. The drug was designed as selective and specific inhibitor of pro-inflammatory receptor signalling. inhibits the process intracellular signalling from to cellular nucleus inflammation via new pathway (inhibition Janus kinases), which unavailable biological medicines. has been for use in treatment patients with moderate severe active RA. may be used combination methotrexate or another...

Ultrasound examinations are recognised as being safe. The greatest epidemiological threat during the performance of examination is transfer pathogenic and opportunistic microorganisms between patients from personnel to patients. Colonization skin with bacteria immunocompromised high risk may lead infection following an ultrasound scan.To identify evaluate strains occurring on equipment subjected unexpected control performed by a local infectious diseases team. We assumed that transducers,...

Corynebacterium coyleae is part of the commensal microflora skin, urethra, mucous membranes, and genital tract. Isolates from patients with urinary tract infection (UTI) were reported, but pathogenic potential this species has not been defined yet. The aim study to determine whether C. could be etiological agent UTI analyze its antibiotic susceptibility. Urine samples cultured quantitatively according accepted laboratory procedures. identification bacterial isolates was carried out using...

Cognitive impairment is a significant clinical problem both in multiple sclerosis (MS) and systemic lupus erythematosus (SLE) patients. In MS cognitive dysfunction has been associated with brain atrophy total demyelinating lesion volume. SLE much less understood, its link to structural damage remains be established. The aim of this study was identify the relationship between subcortical gray matter volume SLE. We recruited 37 38 patients matched by age, disease duration educational level....

Bacteroides fragilis is an anaerobic bacterial species that involved in gynecological infections and pathology. The incidence of vaginal carriage largely unknown, order to study this, 120 pregnant women attending a general hospital for delivery were examined. Cultures positive eight these (6.6%). Interestingly, potential clonal relatedness could be demonstrated among several the nonenterotoxigenic B. strains. Among strains, only one produced metalloprotease enterotoxin. presence gene...

Differentiation of systemic lupus erythematosus (SLE) from multiple sclerosis (MS) can be challenging, especially when neuropsychiatric (NP) symptoms are accompanied by white matter lesions in the brain. Given lack discriminative power currently applied tools for their differentiation, there is an unmet need other measures that aid distinguishing between two autoimmune disorders. In this study we aimed at exploring whether brain atrophy could serve as markers differentiating MS and SLE....

&lt;b&gt;&lt;i&gt;Objective:&lt;/i&gt;&lt;/b&gt; Central nervous system (CNS) involvement in systemic lupus erythematosus (SLE) remains poorly understood. Damage within the CNS is driven by autoimmune response; however, immunopathophysiology of neuropsychiatric (NP) SLE multifactorial. Immune cell neurotrophin production could be neuroprotective against autoimmunity-driven damage, as has been shown multiple sclerosis. The aim this study was to establish whether immune associated with damage...
