Methods: The study included newly diagnosed giant cell arteritis (GCA, n = 27) or Takayasu arteritis (n = 9) patients and healthy control (HC, n = 31) subjects. PET scan and blood samples were obtained before the introduction of treatments.

Long-term safety and efficacy of anakinra and canakinumab in patients with familial Mediterranean fever: a single-centre real-life study with 101 patients.

Objectives: Anakinra and canakinumab are the most commonly used agents in colchicine resistant/intolerant patients. In this study we investigated long-term efficacy and safety of anakinra and canakinumab.

Methods: In this retrospective study, we enrolled 101 adult patients with familial Mediterranean fever (FMF).

Decreased exercise capacity, strength, physical activity level and quality of life in adult patients with familial Mediterranean fever.

Background: Familial Mediterranean fever (FMF) is a systemic autoinflammatory disease that causes recurrent attacks of fever, polyserositis, arthritis or skin eruptions, resulting in pain in the abdomen, muscles, joints and chest. All of these might lead to a reduction in exercise capacity, muscle strength, physical activity level (PAL) and quality of life (QoL). Therefore, assesment of these parameters are important.

Phenotypic characterization of Familial Mediterranean Fever patients harboring variants of uncertain significance.

Background/aim: Familial Mediterranean Fever (FMF) is the prototype of hereditary autoinflammatory disorders and caused by mutations on the MEFV gene located on the short arm of chromosome 16. Although some MEFV variants are clearly associated with disease phenotype, there are numerous variants with unknown clinical association which are termed as variants of uncertain significance (VUS). Here, we present clinical correlations of VUS in a large cohort of adult FMF patients from three tertiary centers located in Central Anatolia.

Work productivity impairment in patients with familial Mediterranean fever and effects of interleukin-1 antagonists.

Introduction: Familial Mediterranean fever (FMF) is characterized by recurrent attacks of fever, serositis, and arthritis. Some patients suffer from associated inflammatory conditions and damage related to FMF that may potentially impair work productivity which have not been studied to date.

Methods: Consecutive FMF patients who were attending a tertiary referral center and age-and sex-matched healthy subjects enrolled into the study.

Appendectomy history is associated with severe disease and colchicine resistance in adult familial Mediterranean fever patients.

Background/aim: Peritonitis attacks of Familial Mediterranean Fever (FMF) usually requires emergency medical admissions and it’s hard to distinguish a typical abdominal attack from surgical causes of acute abdomen. Therefore, history of abdominal surgery, particularly appendectomy, is very common in patients with FMF. However, history of appendectomy might also give some clues about the course of FMF in the adulthood.

Folfirinox versus gemcitabine-cisplatin combination as first-line therapy in treatment of pancreaticobiliary cancer.

Background/aim: The purpose of this study was to compare efficacy and safety of a combination chemotherapy regimen consisting of oxaliplatin, irinotecan, fluorouracil, and leucovorin (FOLFIRINOX) and gemcitabine-cisplatin as first-line therapy in patients with pancreatic cancer.

Materials And Methods: Pancreaticobiliary cancer patients who had Eastern Cooperative Oncology Group performance status score of 0 or 1 (on a scale of 0 to 5, with higher scores indicating greater severity of illness) were evaluated to receive folfirinox or gemcitabine plus cisplatin. The primary endpoints were progression-free and overall survival time.

Compliance of Familial Mediterranean Fever Patients With Regular Follow-up Visits and Associated Factors.

Background: Follow-up is crucial to detect asymptomatic complications of familial Mediterranean fever (FMF). The current European League Against Rheumatism recommendations state that patients with FMF should be evaluated at least every 6 months to monitor attacks, acute phase response, and proteinuria.

Objectives: This study aimed to assess compliance of FMF patients with regular follow-up visits and the associated factors.

Prognostic value of interleukin-18 and its association with other inflammatory markers and disease severity in COVID-19.

Background: The effectual immune response is crucial to defeat viral infections. However, exuberant immune response with features of macrophage activation syndrome (MAS) lead detrimental consequences in COVID-19 patients. Interleukin (IL)-18 is one of the leading cytokines in MAS which has not been studied in COVID-19.
