Role of serum fibroblast growth factor-23 and Klotho level in COVID-19 infection-related mortality: a prospective study.

Introduction: This study investigated the role of fibroblast growth factor 23 (FGF23)/Klotho in the mortality of patients hospitalized with coronavirus disease 2019 (COVID-19), excluding those with chronic kidney disease (CKD).

Methodology: A prospective cross-sectional study was conducted from April 2021 to May 2022. Patients who tested positive for COVID-19 via polymerase chain reaction and were hospitalized, were classified into two groups (survivors and non-survivors) at the end of their hospital follow-up.

Efficacy and safety of Sinovac vaccine administered in patients undergoing hemodialysis.

Introduction: COVID-19 disease is more serious and fatal in patients on dialysis treatment due to their immunosuppressive status. In this study, we aimed to evaluate the protection and safety of Sinovac vaccine, which is an inactivated vaccine, in patients undergoing hemodialysis.

Methodology: A control group consisting of 220 hemodialysis patients (HD group) and 648 healthcare professionals who were healthy in our institution were included in the study.

An unresolved issue: The relationship between spot urine protein-to-creatinine ratio and 24-hour proteinuria.

Objective: To investigate the relationship between spot urine protein-to-creatinine (sP/Cr) ratio and 24-h protein excretion in patients with different diagnoses.

Methods: This retrospective study analysed data from the medical records of patients admitted for24-h proteinuria determination who also had sP/Cr ratio data for the same day.

Results: A total of 1222 urine samples obtained from 694 adult outpatients were analysed.

Hyaluronic Acid as a New Biomarker to Differentiate Acute Kidney Injury From Chronic Kidney Disease.

Introduction: It may be difficult to differentiate acute kidney injury from chronic kidney disease in patients with no past medical reports of kidney function. This study aimed to investigate the role of serum hyaluronic acid (HA), which is known as a marker of fibrosis, in differential diagnosis of kidney failure.

Materials And Methods: A total of 90 patients (52 women and 38 mne) admitted to our renal unit with uremia for the first time were included.

Factors affecting responsiveness to hepatitis B immunization in dialysis patients.

Background: Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are widespread health problems all over the world and have high morbidity and mortality. Hemodialysis patients are more frequently exposed to these viruses as they have poor immune system and frequently undergo parenteral interventions. The vaccination against HBV prevents infection and it has been recommended for the prevention of HBV infection in all susceptible dialysis patients.

Screening Fabry's disease in chronic kidney disease patients not on dialysis: a multicenter study.

Objectives: Fabry's disease is an X-linked inherited, rare, progressive, lysosomal storage disorder, affecting multiple organs due to the deficient activity of α-galactosidase A (α-Gal A) enzyme. The prevalence has been reported to be 0.15-1% in hemodialysis patients; however, the information on the prevalence in chronic kidney disease not on dialysis is lacking.

A novel factor for primary arteriovenous fistula failure: hyperinsulinism.

Introduction: Dysfunction of vascular access is an important reason of morbidity for dialysis patients and it is a major factor affecting the economical burden of hemodialysis. The preferred type of vascular access is creation of an arteriovenous fistula (AVF). However, the problem of fistula maturation rate is still a challenge.

Type 4 renal tubular acidosis in a patient with lupus nephritis.

Although renal tubular acidosis (RTA) is a rare complication of systemic lupus erythematosus (SLE), type 4 RTA associated with lupus nephritis is extremely rare. A 20-year-old woman presented with malaise and edema in the lower extremities and face. She had multiple lymphadenopathies.

Role of lean body mass for estimation of glomerular filtration rate in patients with chronic kidney disease with various body mass indices.

Objective: Glomerular filtration rate (GFR) is the main tool used to diagnose, treat and follow up renal diseases. Age, gender, ethnicity and obesity all affect the relationship between serum creatinine, muscle mass/body weight and GFR. This study aimed to investigate the role of lean body mass for GFR estimation in patients with chronic kidney disease (CKD) with various body mass indices.

[Investigation of anticardiolipin antibodies in chronic hepatitis B infection together with total anti-delta positivity].

Anticardiolipin antibodies (ACAs) are formed against phospholipids in various clinical conditions such as autoimmune diseases, malignancy, infectious diseases, alcohol-related and hepatic cirrhosis. The aims of this study were to investigate the presence of ACAs in patients with chronic hepatitis B together with positive total anti-delta antibodies, and to investigate the relationship between age, gender, and some laboratory parameters (ALT, AST, albumin, globulin, platelet number) of patients with chronic hepatitis delta virus (HDV) infection, who were positive or negative for ACAs. A total of 60 patients (43 male, 17 female) with chronic hepatitis D infection [HBsAg positive, HBeAg negative, anti-HBe positive, anti-HBc IgG positive, anti-HBc IgM negative, total anti-delta positive, anti-HCV negative] and 30 patients (21 male, 9 female) without hepatitis D infection [HBsAg positive, HBeAg negative, anti-HBe positive, anti-HBc IgG positive, anti-HBc IgM negative, total anti-delta negative, anti-HCV negative] as control group were included to the study.

Thrombophilias and arteriovenous fistula dysfunction in maintenance hemodialysis.

Most episodes of fistula thrombosis are consequences of underlying physioanatomic abnormalities. However, some dialysis access thrombosis develops independent from any obvious anatomic cause. We aimed to clarify the role of thrombophilias in primary and secondary AVF failure.

Snakebite-induced acute kidney injury: data from Southeast Anatolia.

Renal failure is an important complication of snakebite and a major cause of mortality. We aimed to study the clinical profile of snake envenomation in Southeast Anatolia, Turkey, in an adult population. We retrospectively analyzed the records of 200 snakebite victims from 1998 to 2006 at the Dicle University School of Medicine, Diyarbakir, Turkey.

Ureterosigmoidostomy[corrected]-associated quadriparesis, non-traumatic rhabdomyolysis, and tetany in an adult.

We report an adult case of ureterosigmoidostomy-associated quadriparesis, rhabdomyolysis, and tetany which may be the first such case in the literature. A 32-year-old female patient was brought to the emergency room of our hospital, having been unable to walk or use her arms for 24 h. Neurological examination revealed quadriparesis.

Thrombosis of temporal artery and renal vein in Kimura-disease-related nephrotic syndrome.

Kimura disease (KD) is an angiolymphoid proliferative disorder of unknown etiology, occurs mainly in Asian patients, presenting with subcutaneous slowly growing masses, with a predilection for preauricular and submandibular regions. The clinical course of the disease is thought to be benign. Concomitant peripheral blood eosinophilia and elevated serum immunoglobulin E levels are often observed.

Rapid tumor lysis syndrome in a patient with metastatic colon cancer as a complication of treatment with 5-fluorouracil/leucoverin and irinotecan.

Tumor lysis syndrome is a potentially fatal complication of anti-cancer therapy that is usually seen in patients with bulky, rapidly proliferating, treatment-sensitive tumors such as hematological malignancies, but it rarely occurs in a variety of solid tumors such as colorectal carcinoma. Combination chemotherapy with infusional 5-fluorouracil/leucoverin and irinotecan has been recently accepted as the first treatment option for metastatic colorectal cancer. We present a case of tumor lysis syndrome in a patient with metastatic colon carcinoma that occurred 72 hrs after the initial course of a combination chemotherapy with irinotecan and 5-fluorouracil/leucoverin.
