Background: A polymeric diet rich in transforming growth factor-beta 2 used as a single nutrient has been shown to induce remission in 79% of children with Crohn's disease.

Objectives: To summarize the experience of several pediatric gastroenterology units in Israel using a TGFβ2[1]-enriched polymeric diet (Modulen IBD) supplementation in children and adolescents with Crohn's disease.

Methods: In a retrospective study we reviewed the charts of 28 children with Crohn's disease (10 girls, 18 boys) who received, in addition to conventional treatment, Modulen IBD™ as a supplement to their regular nutrition. These children were compared with 18 children supplemented with standard polymeric formula (Ensure Plus®) and 18 children without formula supplementation. We recorded clinical manifestations, growth, and the Pediatric Crohn's Disease Activity Index before and after initiation of the polymeric diet.

Results: The Modulen-treated children showed a significant decrease in PCDAI[2] from 34.3 to 15.7 (P < 0.0001). A significant decrease in PCDAI was recorded also in the Ensure Plus group, from 35 to 22 (P = 0.02) but not in the non-supplemented group. Significant improvements in body mass index (P = 0.01) and erythrocyte sedimentation rate (P = 0.03) were recorded at follow-up (median 3.4 months) only in the Modulen IBD group.

Conclusions: In this cohort of children with Crohn's disease, supplementation of the diet with Modulen IBD as well as supplementation with Ensure Plus was associated with a decrease in PCDAI. The children supplemented with Modulen IBD also showed improvement in BMI[3], suggesting an additional advantage of nutritional therapy in children with this disease.

Background: Atopic dermatitis or atopic eczema is an itchy inflammatory skin condition with a predilection of the skin flexures. Most cases start in children although some have been reported in adults. Patients with moderate to severe disease refractory to topical corticosteroid or calcineurin inhibitors may require second-line treatment such as phototherapy or systemic immunosuppressants. Methotrexate therapy has been suggested to be a useful immunosuppressant in adult atopic dermatitis.

Objectives: To further determine the efficacy of low dose methotrexate therapy in adults with new-onset atopic dermatitis or with idiopathic eczema.

Methods: All adult patients with new-onset atopic dermatitis or idiopathic eczema treated by methotrexate in our clinics from 2004 to 2006 were included in the study. All had failed prolonged therapy with oral antihistamines and local corticosteroid creams. Methotrexate, 10–20 mg, was given orally once a week along with folic acid supplements 5 days a week. Additional therapies included predominantly emollients. During the entire treatment period the investigators made global assessments of the clinical response.

Results: Nine patients diagnosed with late-onset atopic dermatitis (n=6) or idiopathic eczema (n=3) were treated with methotrexate. All patients responded to the drug. The initial response was noted after 3–7 weeks. Six patients achieved complete remission after 3 months of methotrexate therapy and three patients had significant improvement. One patient's the condition worsened after achieving a complete response while on methotrexate and it was withdrawn completely. No serious adverse events were noted during treatment.

Conclusions: Low dose methotrexate is an effective therapeutic alternative for late-onset atopic dermatitis or idiopathic eczema in patients unresponsive to local and other systemic therapies.
 

Background: Iron deficiency is the most common single cause of anemia worldwide. Treatment consists of improved nutrition along with oral, intramuscular or intravenous iron administration.

Objectives: To describe the efficacy and adverse effects of intravenous iron sucrose therapy in a group of children with iron deficiency anemia who did not respond to oral iron therapy.

Methods: We conducted a prospective investigation of 45 children, aged 11 months to 16 years, whose oral iron therapy had failed. The children attended the Pediatric Ambulatory Care Unit where they received intravenous iron sucrose infusion.

Results: Forty-four of the 45 patients were non-compliant. Nine had Helicobacter pylori gastritis and 16 patients suffered from intestinal malabsorption from different causes. Before treatment, the blood mean hemoglobin concentration was 7.43 g/dl (range 5–10.1 g/dl). Fourteen days after treatment the mean hemoglobin concentration increased to 9.27 g/dl (SD 1.23) and 6 months later to 12.40 g/dl (SD 1.28). One patient demonstrated a severe side effect with temporary and reversible reduced blood pressure during treatment.

Conclusions: These preliminary data suggest that administration of intravenous iron in pediatric patients is well tolerated and has a good clinical result, with minimal adverse reactions.

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.

There has been a paradigm shift in the treatment of rheumatoid arthritis in recent years. Early and aggressive treatment with good control of disease activity has improved the prognosis of the disease, however, there is significant variability in the response of patients to different therapeutic agents. Hence it is essential to find the predictors of response to a drug at baseline so that we can avoid the delay in achieving remission and improve the outcome. Here we review the literature on available predictors for treatment response in general and specifically for methotrexate and biological agents. We also look at specific scores or indices that can help predict the response in individual patients.

Background: In an era of increasing antimicrobial resistance, knowledge of local antimicrobial susceptibility patterns of common uropathogens is essential for prudent empiric therapy of community-acquired urinary tract infections.

Objectives: To define antimicrobial susceptibility of Gram-negative uropathogens in northern Israel over a 10 year period and to compare it with antibiotic-use patterns in the same community.

Methods: We tested the susceptibility of all Gram-negative urinary isolates from outpatients at HaEmek Medical Center over the years 1995, 1999, 2002 and 2005 to common antimicrobial agents. MIC₉₀ of Escherichia coli to some of these agents was determined and antibiotic consumption data over the years 2000–2005 (DDD/1000/day) were obtained.

Results: We observed a rise in susceptibility rates of E. coli to amoxicillin-clavulanate, trimethoprim-sulfamethoxazole and nitrofurantoin and of other Gram-negative isolates to amoxicillin-clavulanate, ceftriaxone and cephalothin. Susceptibility rates of all Gram-negative uropathogens to ciprofloxacin decreased significantly. MIC₉₀ of E. coli for all drugs tested remained stable. There was a significant decrease in the use nitrofurantoin and TMP-SMX[1] and a significant increase in the use of ampicillin, cephalothin and ceftriaxone.

Conclusions: Antibiotic resistance patterns mostly remained unchanged or improved slightly. There was, however, a constant decrease in susceptibility of all Gram-negative uropathogens to ciprofloxacin. Antibiotic use patterns could not explain the changes seen in antibiotic susceptibility patterns.

Background: The extent of medical and financial problems of polypharmacy in the elderly is disturbing, particularly in nursing homes and nursing departments.

Objectives: To improve drug therapy and minimize drug intake in nursing departments.

Methods: We introduced a geriatric-palliative approach and methodology to combat the problem of polypharmacy. The study group comprised 119 disabled patients in six geriatric nursing departments, and the control group 71 patients of comparable age, gender and co-morbidities patients in the same wards. After 12 months, we assessed whether any change in medications affected the death rate, referrals to acute care facility and costs.

Results: A total of 332 different drugs were discontinued in 119 patients (average of 2.8 drugs per patient) and was not associated with significant adverse effects. The overall rate of drug discontinuation failure was 18% of all patients and 10% of all drugs. The 1 year mortality rate was 45% in the control group but only 21% in the study group (P < 0.001, chi-square test). The patients’ annual referral rate to acute care facilities was 30% in the control group but only 11.8% in the study group (P < 0.002). The intervention was associated with a substantial decrease in the cost of drugs.

Conclusions: Application of the geriatric-palliative methodology in the disabled elderly enables simultaneous discontinuation of several medications and yields a number of benefits: reduction in mortality rates and referrals to acute care facilities, lower costs, and improved quality of living.
