Background: Cannabidiol (CBD)-based treatments for several diseases, including Tourette’s

syndrome, multiple sclerosis, epilepsy, movement disorders and glaucoma, are proving to be beneficial and the  scientific clinical background of the drug is continuously evolving. 

Objectives: To investigate the short-term effect of CBD-enriched hemp oil for relieving symptoms and improving the life quality (QOL) in young girls with adverse drug effects (ADRs) following human papillomavirus (HPV) vaccine. 

Methods: In this anecdotal, retrospective, “compassionate-use”, observational, open-label study, 12 females (age 12–24 years) with severe somatoform and dysautonomic syndrome following HPV vaccination were given sublingual CBD-rich hemp oil drops, 25 mg/kg per day supplemented by 2–5 mg/ml CBD once a week until a maximum dose of 150 mg/ml CBD per day was reached over a 3 month period. Patients’ quality of life was evaluated using the medical outcome short-form health survey questionnaire (SF-36).

Results: Two patients dropped out due to iatrogenic adverse events and another two patients stopped the treatment early due to lack of any improvement. SF-36 showed significant benefits in the physical component score (P < 0.02), vitality (P < 0.03) and social role functioning (P < 0.02) after the treatment. The administration of hemp oil also significantly reduced body pain according to the SF-36 assessment. No significant differences from the start of treatment to several months post-treatment were detected in role limitations due to emotional reactions (P = 0.02).

Conclusions: This study demonstrated the safety and tolerability of CBD-rich hemp oil and the primary efficacy endpoint. Randomized controlled trials are warranted to characterize the safety profile and efficacy of this compound.

 

Background: Anti-BLyS treatment with the human belimumab monoclonal antibody was shown to be a safe and effective therapeutic modality in lupus patients with active disease (i.e., without significant neurological/renal involvement) despite standard treatment.

Objectives: To evaluate the “real-life” safety and efficacy of belimumab added to standard therapy in patents with active lupus in five Israeli medical centers.

Methods: We conducted a retrospective open-labeled study of 36 lupus patients who received belimumab monthly for at least 1 year in addition to standard treatment. Laboratory tests (C3/C4, anti dsDNA autoantibodies, chemistry, urinalysis and complete blood count) were done every 3–4 months. Adverse events were obtained from patients’ medical records. Efficacy assessment by the treating physicians was defined as excellent, good/partial, or no response.

Results: The study group comprised 36 lupus patients (8 males, 28 females) with a mean age of 41.6 } 12.2 years. Belimumab was given for a mean period of 2.3 } 1.7 years (range 1–7). None of the patients discontinued belimumab due to adverse events. Four patients (11.1%) had an infection related to belimumab. Only 5 patients (13.9%) stopped taking belimumab due to lack of efficacy. The response was excellent in 25 patients (69.5%) and good/partial in the other 6 (16.6%). Concomitantly, serological response (reduction of C3/C4 and anti-dsDNA autoantibodies) was also observed. Moreover, following belimumab treatment, there was a significant reduction in the usage of corticosteroids (from 100% to 27.7%) and immunosuppressive agents (from 83.3% to 8.3%).

Conclusions: Belimumab, in addition to standard therapy, is a safe and effective treatment for active lupus patients.

Behçet's disease (BD) is a multi-systemic disorder of unknown etiology characterized by relapsing oral-genital ulcers, uveitis, and involvement of the articular, gastrointestinal, neurologic, and vascular systems. The choice of treatment is based on the severity of systemic involvement, clinical presentation and the site affected, and includes corticosteroids, azathioprine, interferon, cyclophosphamide, methotrexate or tumor necrosis factor-alpha and interleukin-1 blockers. We present a case series of four refractory BD patients successfully treated with intravenous immunoglobulins (IVIG). All patients fulfilled International Study Group criteria. The patients’ mean age was 38.75 ± 12.09 years and mean disease duration 10.25 ± 8.5 years. Human leukocyte antigen B51 was positive in two of four patients. In addition to oral aphthosis, all patients suffered from genital ulcers and cutaneous BD-related manifestations; central nervous system involvement and arthralgia were found in two patients. Peripheral nervous system, gastrointestinal and eye involvement occurred in 25% of cases. In all patients, previously treated according to EULAR recommendations without reaching satisfactory results, IVIG induced immediate and sustained response over time without incurring any side effects. We propose IVIG administration as an additional effective and safe treatment option in patients with severe and resistant BD.

Background: The efficacy of subcutaneous immunotherapy for the treatment of allergic rhinitis, allergic conjunctivitis, allergic asthma and stinging insect hypersensitivity has been demonstrated in several studies.

Objectives: To investigate the effectiveness and side effects of immunotherapy in Israel and the relationship between local and systemic side effects.

Methods: This retrospective study was based on patient records and a computerized database for drug dispensing over a 5 year period. Success was rated as partial or complete. Side effects were classified as local or systemic. Systemic side effects were further classified according to severity, as mild (cutaneous), moderate (respiratory symptoms), or severe (cardiovascular).

Results: Of the 135 patients on aero-allergen immunotherapy who reached maintenance, 120 (88.9%) exhibited complete or partial improvement and 15 (11.1%) did not improve. All of the 44 patients on hymenoptera immunotherapy reached effective maintenance doses. The mean percent side effects calculated per treatment (injection) were 2.49 for local and 1.58 for a systemic reaction during the build-up phase, and 1.13 and 1.12 during the maintenance phase, respectively. Rates of systemic reactions were 1.3% for cutaneous, 1.14% for respiratory and 0.97% for cardiovascular reactions during the build-up phase, and 1.11%, 0.53%, and 0.51% during the maintenance phase, respectively. The odds of systemic reactions were significantly higher in patients with local reactions both in the build-up phase (P = 0.03) and in the maintenance phase (P = 0.0003). The number of annual medications dispensed per patient decreased from 31.5 to 26.0 during the first year after reaching maintenance, and to 22.5 in the second year. Pharmaceutical costs were 67% lower 1 year after the start of the maintenance phase, compared to the year before the start of immunotherapy, and 63% lower in the second year (P = NS).

Conclusions: Immunotherapy was effective and safe. Recognizing the benefits and safety of immunotherapy is necessary for physicians and health authorities in order to provide better care for allergic patients.

Background: Tinea pedis is a common chronic skin disease; the role of contaminated clothes as a possible source of infection or re-infection has not been fully understood. The ability of ultraviolet light to inactivate microorganisms has long been known and UV is used in many applications.

Objectives: To evaluate the effectivity of sun exposure in reducing fungal contamination in used clothes.

Methods: Fifty-two contaminated socks proven by fungal culture from patients with tinea pedis were studied. The samples were divided into two groups: group A underwent sun exposure for 3 consecutive days, while group B remained indoors. At the end of each day fungal cultures of the samples were performed.

Results: Overall, there was an increase in the percentage of negative cultures with time. The change was significantly higher in socks that were left in the sun (chi-square for linear trend = 37.449, P < 0.0001).

Conclusions: Sun exposure of contaminated clothes was effective in lowering the contamination rate. This finding enhances the current trends of energy saving and environmental protection, which recommend low temperature laundry.

Methods: In this retrospective multicenter open-label study we examined the efficacy and tolerability of VNS in patients in five adult and pediatric epilepsy centers in Israel. All patients had drug-resistant epilepsy and after VNS implantation in 2006–2007 were followed for a minimum of 18 months. Patients were divided into two age groups: < 21 and > 21 years old.

Results: Fifty-six adults and children had a stimulator implanted in 2006–2007. At 18 months post-VNS implantation, none of the patients was seizure-free, 24.3% reported a reduction in seizures of ≥ 75%, 19% reported a 50–75% reduction, and 10.8% a 25–50% reduction. The best response rate occurred in patients with complex partial seizures. Among these patients, 7 reported a ≥ 75% reduction, 5 patients a 50–75% reduction, 3 patients a 25–50% reduction, and 8 patients a < 25% reduction. A comparison of the two age groups showed a higher reduction in seizure rate in the older group (< 21 years old) than the younger group.

Conclusions: VNS is a relatively effective and safe palliative method for treating refractory epilepsy in both adults and children. It is an alternative treatment for patients with drug-resistant epilepsy, even after a relatively longed disease duration, who are not candidates for localized epilepsy surgery.

Objectives: To evaluate the efficacy and safety of a simple bi-daily treatment regimen with the combination of pyridoxine (50 mg twice daily) and doxylamine (25–50 mg) as an alternative treatment for NVP.

Methods: A prospective case-controlled observational study of mother-infant pairs was conducted between February 2008 and December 2010. All women who contacted the Beilinson Teratology Information Service (BELTIS) regarding treatment of NVP were eligible for inclusion. Using data on NVP severity, treatment efficacy and outcomes, we compared the two groups of women: those treated with the combination of pyridoxine and doxylamine (treatment group, n=29) and those treated with metoclopramide (control group, n=29).

Results: Moderate to severe symptoms were present in 97% of the treatment group women vs. 69% of control group women (P < 0.01). Despite increased symptom severity in the treatment group, the combination regimen was efficacious: 20/29 (69%) vs. 18/25 (72%) in the treatment vs. control women respectively (P = 0.65). There were no congenital anomalies in the treatment group. Follow-up was normal for all infants.

Conclusions: Bi-daily combination therapy with pyridoxine and doxylamine for NVP is safe, has comparable efficacy to metoclopramide, and is a treatment alternative in countries where Diclectin is not available. Despite symptoms warranting counseling by a teratology information service, more than a third of women do not take the suggested treatment.

Background: In the last two decades milk oral immunotherapy has gained interest as an effective treatment option for milk-allergic patients.

Objectives: To report on the efficacy of a milk oral immunotherapy.

Methods: Children with immunoglobulin E-mediated cow’s milk allergy were included in the protocol. The treatment consisted of an induction phase in which milk doses were increased weekly in the hospital, while the tolerated dose was continued daily at home. The goal was to achieve a minimum milk intake of 200 ml a day. During the maintenance phase, patients ingested at least 200 ml of milk in a single dose every day.

Results: The protocol was applied to 105 milk-allergic children diagnosed by specific IgE to milk and controlled oral food challenge. The mean duration of the induction phase was 19 weeks. Of the 105 subjects, 86 (81.9%) successfully complied with the protocol and 19 (19.1%) failed. Causes of failure were moderate/severe reactions in 12 patients (12.44%) and personal reasons in 7 (6.66%). A total of 182 adverse reactions occurred during the induction phase, most of them mild. Baseline specific IgE to milk and casein were significantly lower (P < 0.05) in the successfully treated group compared to the group in which the treatment failed.

Conclusions: Milk oral immunotherapy is a safe and effective treatment for milk-allergic children, although adverse reactions may occur. Baseline milk and casein-specific IgE may be useful to predict a good response to milk oral immunotherapy.

Background: Glioblastoma multiforme (GBM) is an ultimately fatal disease that affects patients of all ages. Elderly patients (65 years and older) constitute a special subgroup of patients characterized by a worse prognosis and frequent comorbidities.

Objectives: To assess the efficacy of different treatment modalities in terms of survival in elderly patients with GBM¹.

Methods: Using retrospective analysis, we extracted, anonymized and analyzed the files of 74 deceased patients (aged 65 or older) treated for GBM in a single institution.

Results: Mean survival time was 8.97 months and median survival time 7.68 months. Patients who underwent tumor resection had a mean survival of 11.83 months, as compared to patients who underwent no surgical intervention or only biopsy and had a mean survival of 5.22 months (P < 0.0001). Patients who underwent full radiation treatment had a mean survival of 11.31 months, compared to patients who received only partial radiotherapy or none at all and had a mean survival of 4.09 months (P < 0.0001). Patients who underwent chemotherapy had a mean survival 12.4 months, compared to patients who did not receive any chemotherapy and had a mean survival of 5.89 months (P < 0.001).

Conclusions: Age alone should not be a factor in the decision on which treatment should be given. Treatment should be individualized to match the patient’s overall condition and his or wishes, while taking into consideration the better overall prognosis expected with aggressive treatment.
 

Background: ST-elevation myocardial infarction is caused by occlusive coronary thrombosis where antecedent plaque disruption occurs. When treating STEMI[1] the main goal is to achieve prompt reperfusion of the infarction area. Several studies have demonstrated the efficacy of an aspiration device before percutaneous coronary intervention in patients with acute myocardial infarction.

Objectives: To determine the added value of thrombus aspiration prior to primary PCI[2] by comparing AMI[3] patients with totally occluded infarct-related artery treated with routine primary PCI to those treated with extraction device prior to primary PCI.

Methods: The study group comprised 122 consecutive patients with AMI and a totally occluded infarct artery (TIMI flow 0) who underwent primary PCI. The patients were divided into two groups: 68 who underwent primary PCI only (control group) and 54 who underwent primary thrombus extraction with an extraction device before PCI (extraction group). Baseline clinical and lesion characteristics were similar in both groups. Final TIMI grade flow and myocardial blush as well as 1 year mortality, target lesion revascularization, recurrent myocardial infarction, unstable angina and stroke were compared between the two groups.

Results: Primary angiographic results were better for the extraction group versus the control group: final grade 3 TIMI flow was 100% vs. 95.6% (P = 0.03) and final grade 3 myocardial blush grade 50% vs. 41.18% (although P was not significant). Long-term follow-up total MACE[4] showed a non-significant positive trend in the extraction group (12.96% vs. 24.71%, P = 0.26).

Conclusions: The use of extraction devices for intracoronary thrombectomy during primary PCI in patients with totally occluded infarct artery significantly improved epicardial reperfusion in the infarct-related vessel and showed a trend for more favorable long-term outcome.
