Background: Tocilizumab is an interleukin 6 (IL-6) receptor antagonist used treat moderate to severe active rheumatoid arthritis (RA). Both intravenous (IV) and subcutaneous (SC) routes are approved for the treatment of adults with RA.

Objectives: To evaluate SC tocilizumab in a real-life clinical setting.

Methods: Our study was a multi-center, open-label, single-arm study. Participants were adults with a diagnosis of active RA, previously treated with disease-modifying antirheumatic drugs (DMARDs), with or without biologic agents. Participants received a weekly SC injection of tocilizumab 162 mg as monotherapy or in combination with methotrexate or DMARDs for 24 weeks. Efficacy, safety, and immunogenicity were assessed.

Results: Treatment of 100 patients over 24 weeks resulted in improvement in all efficacy parameters assessed: Clinical Disease Activity Index, Disease Activity Score using 28 joint counts and erythrocyte sedimentation rate, American College of Rheumatology response scores, Simplified Disease Activity Index, tender and swollen joint counts, and patient-reported outcomes including fatigue, global assessment of disease activity, pain, and Health Assessment Quality of Life Disease Index. Improvement was achieved as early as the second week of treatment. There were 473 adverse events (AEs)/100 patient-years (PY) and 16.66 serious AEs/100 PY. The most common AEs were neutropenia (12%), leukopenia (11%), and increased hepatic enzymes (11%). Of a total of 42 PY, the rates of serious infections and AEs leading to discontinuation were 4.8, and 11.9 events/100 PY, respectively.

Conclusions: The safety, tolerability, and efficacy profile of tocilizumab SC were comparable to those reported in other studies evaluating the IV and SC routes of administration.

Background: Chronic fatigue is common among patients with rheumatoid arthritis (RA), affecting quality of life. Osteoporosis is a prevalent co-morbidity in RA patients.

Objectives: To assess the effect of long-term treatment with tocilizumab on fatigue and bone mineral density (BMD) in RA patients with inadequate response to synthetic or biologic disease-modifying anti-rheumatic drugs. 

Methods: In this multicenter, open-label, non-controlled, single-arm study, patients ≥ 18 years of age received intravenous tocilizumab 8 mg/kg every 4 weeks for 96 weeks. The primary outcome was the change in Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue score from baseline to weeks 24, 48, 72, and 96. BMD was assessed before and 96 weeks after treatment. 

Results: The study comprised 145 patients (mean age 53.4 ± 13.4 years, 83.4% women). Of these, 88 (60.7%) completed the 2 year treatment period. The mean FACIT-Fatigue score improved consistently starting from week 4 and showed a statistically significant increase of 5.0 ± 9.7, 6.8 ± 10.5, 7.3 ± 10.9, and 7.3 ± 10.4 from baseline to weeks 24, 48, 72, and 96, respectively (P < 0.0001). Mean BMD of femoral neck and total spine remained stable. Disease activity, acute phase reactants, and composite efficacy measures decreased during the study, while hemoglobin levels increased. Adverse events and serious adverse events were as expected for the known and previously described data.

Conclusions: Tocilizumab therapy for 2 years significantly and clinically decreased fatigue. BMD remained stable and no new safety issue was reported.

 Background: Takayasu's arteritis is a rare, probably underdiagnosed disorder in Israel.

Objective: To evaluate the contribution of computerized tomography to the diagnosis of Takayasu's arteritis.

Methods: A retrospective analysis of the diagnostic process was recently conducted in three consecutive patients diagnosed over the last 3 years.

Results: Three females of Arab origin with Takayasu's arteritis were recently identified by CT. In two of the three patients the imaging procedure was performed for different working hypotheses, and the radiological findings (wall thickening, perivascular edema, and segmental intraluminal obliteration of the aorta and its major branches) were unexpected. In these two patients, repeated physical examination following the imaging procedure disclosed initially missed findings that could have led to an earlier consideration of Takayasu's arteritis (bruits above the epigastrium, subclavian and carotid arteries, and absent brachial pulses). Retrospective analysis of the patients' symptoms following CT revealed the true nature of the patients' misinterpreted complaints (e.g., typical abdominal angina replaced a faulty obtained history compatible with renal colic or dyspepsia). In the third patient CT was performed for the evaluation of an epigastric bruit associated with constitutional complaints. The diagnosis of aortitis, based upon the presence of diffuse aortic wall thickening and edema of the surrounding fat, without intraluminal narrowing, could have been missed by angiography, the traditional "gold standard" diagnostic procedure. All three patients complained of ill-defined epigastric abdominal pain and had epigastric tenderness during examination.

Conclusions: CT has the potential for detecting Takayasu's disease and may be superior to angiography, particularly at the early non-obliterative stage. Since the diagnosis of Takayasu's disease is rarely considered, the expanding use of CT and MRI technologies may reveal missed cases that are evaluated for other plausible diagnoses. The true incidence of Takayasu's arteritis in Israel may be much higher than reported, particularly in the Arab population. Our findings suggest that epigastric tenderness, originating from active inflammatory reaction in the abdominal aortic wall, should be considered as a diagnostic criterion of Takayasu's aortitis.
