Association of focus score and extraglandular involvement in Sjögren's syndrome: A study on antinuclear antibodies and minor salivary gland pathology.

Objectives: This study aimed to investigate the relationship between patients with and without extraglandular involvement in Sjögren's syndrome (SS) by analyzing ANA (antinuclear antibody) and ENA (extractable nuclear antigen) results and minor salivary gland pathology findings.

Patients And Methods: A total of 265 (245 females; 20 males; mean age: 50.4±12.

Corneal nerve loss and increased Langerhans cells are associated with disease severity in patients with rheumatoid arthritis.

Background/objectives: Rheumatoid arthritis (RA) is a multisystem autoimmune disorder characterized by articular and extra-articular manifestations. Neuropathy is a poorly studied manifestation of RA. The aim of this study was to utilize the rapid non-invasive ophthalmic imaging technique of corneal confocal microscopy to identify whether there is evidence of small nerve fibre injury and immune cell activation in patients with RA.

Is the Thoracic and Back Muscle Mass Associated with Disease Severity in Patients with COVID-19?

Objective: With this study, it was aimed to investigate whether the thoracic muscle mass of patients with coronavirus disease 2019 was related to disease severity and disease characteristics and to evaluate whether muscle mass measurement had a predictive effect on predicting disease severity.

Material And Methods: Two hundred twenty-three subjects (patient group = 161 and control = 62) who presented to our coronavirus disease 2019 outpatient clinic between May 2020 and September 2020 were included in the study. The medication, oxygen, and intubation requirements of the patients and their disease duration and hospital stay were also recorded.

Subclinical Corneal Nerve Fiber Damage and Immune Cell Activation in Systemic Lupus Erythematosus: A Corneal Confocal Microscopy Study.

Purpose: The purpose of this study was to evaluate the utility of corneal confocal microscopy (CCM) in identifying small nerve fiber damage and immune cell activation in patients with systemic lupus erythematosus (SLE).

Methods: This cross-sectional comparative study included 39 consecutive patients with SLE and 30 healthy control participants. Central corneal sensitivity was assessed using a Cochet-Bonnet contact corneal esthesiometer and a laser scanning CCM (Heidelberg, Germany) was used to quantify corneal nerve fiber density (CNFD), nerve branch density (CNBD), nerve fiber length (CNFL), and Langerhans cell (LC) density.

Investigation of the effects of angiotensin converting enzyme inhibitors and angiotensin receptor blockers on anemia in patients with normal or mildly low glomerular filtration rate.

Background/aim: The relationship between the activation of the renin-angiotensin system and the increase in erythropoiesis has been shown in many studies. In addition, the use of angiotensin converting enzyme inhibitors (ACEIs) or angiotensin-receptor blockers (ARB) has been reported to reduce hemoglobin levels in various patient groups at risk for secondary erythrocytosis/polycythemia. The aim of our study is to investigate whether there is a change in hemoglobin levels after starting ACEIs or ARBs in patients who have not used them before.

The association of Helicobacter pylori with choroidal and retinal nerve fiber layer thickness.

Purpose: To investigate the effect of Helicobacter pylori (H. pylori) infection on choroidal thickness (CT) and retinal nerve fiber layer thickness (RNFLT).

Methods: The study included 25 patients with H.
