Temporary hypothyroidism in severe crush syndrome: a potential novel entity.

Background: Thyroid hormone synthesis is a complex process in the human body. Although the thyroid gland is essential for thyroid hormone synthesis, skeletal muscles also have crucial roles in thyroid hormone metabolism due to the deiodinase activities of the muscle cells. Hypothyroidism-related myopathy is a well-known entity.

Daily variability of acid-base status and determinants of serum bicarbonate in hemodialysis patients.

Aim: We aimed to evaluate daily variability of bicarbonate in hemodialysis (HD) patients and identify the factors which affect that issue.

Materials And Methods: Blood samples of 41 patients for bicarbonate (total carbon dioxide (CO)) and blood gas analysis (pH, bicarbonate (HCO)) were obtained, pre-dialysis and post-dialysis, on the first, second, and third session of the week. Those with pre-dialysis HCO < 22 mmol/L in all sessions were classified as acidotic.

Prognostic value of histopathological scoring and grading in patients with renal AA amyloidosis.

Objective: The amount and distribution pattern of amyloid deposits may contribute to renal function and outcome, given the great diversity of renal involvement in amyloidosis. The aim of this study was to analyze the impact of histological characteristics of patients with biopsy-proven renal AA amyloidosis (AAA) on renal outcome.

Methods: Renal biopsies of 37 patients with AAA were re-evaluated.

The relationship between glomerular IgG staining and poor prognostic findings in patients with IgA nephropathy: the data from TSN-GOLD working group.

Background: Galactose-deficient IgA1 (Gd-IgA1) has an increased tendency to form immunocomplexes with IgG in the serum, contributing to IgAN pathogenesis by accumulating in the glomerular mesangium. Several studies showed that glomerular IgG deposition in IgAN is an important cause of mesangial proliferation and glomerular damage. This study aims to determine the association of the positivity of IgG and the intensity of IgG staining with a poor renal prognosis.

Can systemic immune inflammation index at admission predict in-hospital mortality in chronic kidney disease patients with SARS-CoV-2 infection?

Background And Aim: Patients with chronic kidney disease (CKD) are susceptible to SARS-CoV-2 infection and more prone to develop severe disease. It is important to know predictors of poor outcomes to optimize the strategies of care.

Methods: 93 patients with CKD and 93 age-sex matched patients without CKD were included in the study.

Spectrum of biopsy-based renal disease in an elderly Turkish population.

Aim: The prevalence of kidney disease and the number of renal biopsies performed in the elderly are increasing with aging of the population. We aimed to analyze the clinicopathological findings of kidney diseases in the elderly (≥ 65 years), in comparison with their younger counterparts (aged 16 - 64 years).

Materials And Methods: The data at the time of renal biopsy were obtained by reviewing medical records and the biopsy reports of the patients retrospectively.

COVID-19 in hemodialysis patients: a single-center experience in Istanbul.

Objective: Coronavirus disease 2019 (COVID-19) causes a wide spectrum of symptoms, from asymptomatic conditions to severe inflammatory response. Hemodialysis (HD) patients have a higher risk for developing severe COVID-19 because of older age, multiple co-morbid conditions, and impaired immune system compared to the general population. As little is known about these special groups, we evaluated the clinical characteristics and outcomes of HD patients with COVID-19.
