 Background:  Pomegranate extract (POMx) consumption has been shown to reduce the incidence and severity of collagen-induced arthritis in mice.

Objectives:  To investigate whether pomegranate consumption affects disease activity in patients with rheumatoid arthritis (RA), in relation to their serum oxidative status.

Methods:  In this pilot 12 week open-labeled study eight patients with active RA consumed POMx (10 ml/day) for 12 weeks. Patients’ joint status and serum oxidative status (lipid peroxidation, total thiols group, paraoxonase 1 activity) were evaluated at baseline and at week 12.

Results:  Six patients completed the study. POMx consumption significantly (P < 0.02) reduced the composite Disease Activity Index (DAS28) by 17%, which could be related mostly to a significant (P < 0.005) reduction in the tender joint count (by 62%). These results were associated with a significant (P < 0.02) reduction in serum oxidative status and a moderate but significant (P < 0.02) increase in serum high density lipoprotein-associated paraoxonase 1 (PON1) activity. The addition of POMx to serum from RA patients reduced free radical-induced lipid peroxidation by up to 25%.

Conclusions:  The pomegranate consumption reduced DAS28 in RA patients, and this effect could be related to the antioxidative property of pomegranates. Dietary supplementation with pomegranates may be a useful complementary strategy to attenuate clinical symptoms in RA patients.

Background: Overlap syndrome is an entity that satisfies the criteria of at least two connective tissue diseases. These conditions include systemic sclerosis, dermatomyositis or polymyositis, Sjogren's syndrome, rheumatoid arthritis and systemic lupus erythematosus. A combined pathology has impact on the clinical features, diagnosis and treatment.

Objectives: To analyze the features of SSc[1] patients with overlap syndrome registered in the European (EUSTAR) database at our center and to review the literature focusing on clinical and diagnostic issues and new treatments.

Methods: We studied the medical records of 165 consecutive SSc patients and reviewed cases with scleroderma overlap syndrome. Using the key words “overlap syndrome," "systemic sclerosis," “connective tissue disease” and “biological agents” we conducted a PubMed search for the period 1977 to 2009.

Results: Forty patients satisfied the criteria for scleroderma overlap syndrome. The incidence of additional connective tissue diseases in the whole group and in the overlap syndrome group respectively was: dermatomyositis or polymyositis 11.5% and 47.5%, Sjogren's syndrome 10.3% and 42.5%, rheumatoid arthritis 3.6% and 15.4%, and systemic lupus erythematosus 1.2% and 5.0%. Coexistence of SSc and another CTD[2] aggravated the clinical course, especially lung, kidney, digestive, vascular and articular involvement. Non-rheumatic complications mimicked SSc complications. An additional rheumatic or non-rheumatic disease affected treatment choice.

Conclusions: The definition of scleroderma overlap syndrome is important, especially in patients who need high-dose corticosteroids for complications of a CTD. The use of novel biological therapies may be advocated in these patients to avoid the hazardous influences of high-dose steroids, especially renal crisis. In some overlap syndrome cases, biological agents serve both conditions; in others one of the conditions may limit their use. In the absence of formal clinical trials in these patients a cautious approach is preferred.

Background: Infliximab and etanercept have been included in the Israeli national list of health services since 2002 for rheumatoid arthritis and juvenile idiopathic arthritis, and since 2005 for psoriatic arthritis and ankylosing spondylitis. The regulator (Ministry of Health and health funds) mandates using fixed doses of infliximab as the first drug of choice and increased dosage is not allowed. For other indications (e.g., vasculitis), anti-tumor necrosis factor therapy is given on a "compassionate" basis in severe refractory disease.

Objectives: To describe our experience with anti-TNF[1] therapy in a single tertiary referral center in northern Israel and to analyze the impact of the national health policy on the results.

Methods: We reviewed the medical records of patients who received anti-TNF therapy in our institution, and analyzed demographic data, diagnosis, clinical and laboratory features, previous and current therapies, and anti-TNF treatment duration and side effects.

Results: Between 2001 and 2006, 200 patients received anti-TNF therapy for rheumatoid arthritis (n=108), juvenile idiopathic arthritis (n=11), psoriatic arthritis (n=37), ankylosing spondylitis (n=29), adult Still's disease (n=4), overlap disease (RA[2] and scleroderma or polymyositis, n=6), temporal arteritis (n=1), polyarteritis nodosa (n=1), dermatomyositis (n=1), amyloidosis secondary to RA (n=1) and Wegener's granulomatosis (n=1). Forty percent of RA patients discontinued the first anti-TNF agent due to side effects or insufficient response. Higher sedimentation rate and lower or negative rheumatoid factor predicted better response to therapy among RA patients. AS[3] and PS[4] patients had a better safety and efficacy profile. Severe infections occurred in 2% of patients. All eight patients who presented lung involvement as part of their primary rheumatic disease remained stable or improved. A significant improvement was achieved in all six patients with overlap disease.

Conclusion: Our daily practice data are generally in agreement with worldwide experience. The ‘deviations’ might be explained by the local health policy at that time. The impact of health policy and economic and administrative constraints should be taken into account when analyzing cohort daily practice data.

Objective: To report our experience with terlipressin treatment for facilitation of transport to distant facilities for diagnostic or therapeutic procedures in septic patients treated with norepinephrine.

Methods:  We conducted a retrospective analysis of the records of our ICU[1], identifying the patients with septic shock who required norepinephrine for hemodynamic support.

Results: Terlipressin was given to 30 septic shock patients (15 females and 15 males) who were on high dose norepinephrine (10 μg/min or more) in order to facilitate their transport outside the ICU. The dose of terlipressin ranged from 1 to 4 mg, with a mean of 2.13 ± 0.68 mg. The dose of norepinephrine needed to maintain systolic blood pressure above 100 mmHg decreased following terlipressin administration, from 21.9 ± 10.4 μg/min (range 5–52 μg/min) to 1.0 ± 1.95 (range 0–10) (P < 0.001). No patients required norepinephrine dose adjustment during transport. No serious complications or overshoot in blood pressure values were observed following terlipressin administration. Acrocyanosis occurred only in eight patients receiving more than 1 mg of the drug. The overall mortality rate was 50%.

Conclusions: Our data suggest that terlipressin is effective in septic shock. Because it is long-acting and necessitates less titration it might be indicated for patient transportation.
