Background: Strategies aimed at expanding the organ donor pool have been sought, which has resulted in renewed interest in donation after cardio-circulatory death (DCCD), also known as non-heart beating donors (NHBDs).

Objectives: To describe the derivation and implementation of a protocol for DCCD in Israel and report on the results with the first six cases. 

Methods: After receiving approval from an extraordinary ethics committee, Ministry of Health, the steering committee of the National Transplant Center defined and reached consensus on the unique challenges presented by a DCCD program. These protocol included medical aspects (construction of a clinical pathway), social and ethical aspects (presentation of the protocol at a public gathering(, legal/ethical aspects (consent for organ preservation procedures being either implied if the donor had signed an organ donor card or received directly from a surrogate decision maker), and logistical aspects (pilot study confined to kidney retrieval and to four medical centers). Data regarding organ donors and recipients were recorded.

Results: The protocol was implemented at four medical centers. Consent for organ donation was received from four of the six potential donors meeting criteria for inclusion, in all cases, from a surrogate decision maker. Of the eight kidneys retrieved, only four were suitable for transplantation, which was carried out successfully for four recipients. Graft function remained normal in all cases in 6–12 months follow-up. 

Conclusions: The DCCD program was successfully implemented and initial results are encouraging, suggesting that expansion of the program might further aid in decreasing the gap between needs and availability of organs.

 

Background: The goals of treatment for rheumatoid arthritis (RA) are remission and low disease activity (LDA). However, many patients do not reach or maintain these targets with regard to disease control. 

Objective: To identify predictive factors of remission/LDA in a cohort of RA patients who started treatment with first line tumor necrosis factor-inhibitors (TNF-i). 

Methods: We included 308 RA patients treated with first line TNF-i for 2 years to evaluate remission/LDA based on the 28-joint disease activity score (DAS28). Predictive factors considered for achievement of remission/LDA were: gender, age at the time of TNF-i treatment, early arthritis, baseline C-reactive protein (CRP) and erythrocyte sedimentation rate levels, RF/anti-citrullinated protein antibody positivity, good/moderate European League Against Rheumatism response at 6 months, co-morbidities, and concomitant disease modifying antirheumatic drugs (DMARDs). Intention to treat, receiver operating characteristic curve, and univariate and multivariate analyses by logistic regression were performed. 

Results: Positive predictors of remission/LDA in both the univariate and the multivariate analyses were: male gender, age at the time of TNF-i treatment ≤ 54 years, negative baseline CRP, and concomitant DMARDs. The presence of any co-morbidity resulted to be a negative predictor of remission/LDA in both the univariate and the multivariate analyses. 

Conclusions: Demographic and clinical features were identified as reliable predictors of both the achievement and the maintenance of treatment targets in a cohort of RA patients treated for 2 years with first line TNF-i. 

 

Background: Evidence has shown that pregnancy failure (PF) in women with systemic sclerosis (SSc) consists mainly of preterm delivery (PD) and intrauterine growth restriction (IUGR). Thyroid dysfunction (TD) and Hashimoto's thyroiditis (HT) represent a common feature of SSc. Since TD has been associated with PF, its presence in SSc women may potentially affect pregnancy outcome. 

Objectives: To analyze the interplay between TD and PF in a cohort of SSc women. 

Methods: SSc women (n=77) and age-matched controls from the general obstetric population (n=50) were included. Clinical/biochemical/instrumental data exploring TD and the visceral involvement were collected in the context of a clinical practice setting. Pregnancy outcome was assessed by registering the history of primary infertility, recurrent spontaneous abortion, PD (≤ 37 gestational week), IUGR, and intrauterine fetal death. 

Results: A higher prevalence of PD/IUGR was recorded in the SSc cohort than the controls (P = 0.04). SSc women with PF showed a higher prevalence of diffuse SSc than women without PF (P = 0.03). Scl-70 positive SSc women had a higher prevalence of PF than women with anti-centromere positivity (P = 0.01). A higher prevalence of HT was recorded in SSc women with PF than in patients without (P = 0.04). 

Conclusions: Our findings support the evidence that women with SSc can have successful pregnancies despite a higher prevalence of PD/IUGR. Diffuse SSc and Scl-70 positivity may predispose SSc women to PF. Routine thyroid workup may be included in the multi-specialist monitoring of SSc women for the early detection of thyroid dysfunctions.

 

Background: Cytomegalovirus (CMV) infection during pregnancy is the most common cause of intrauterine infection, and is a common cause of sensorineural hearing loss and mental retardation. 

Objectives: To evaluate trends in amniocentesis and pregnancy outcome in women with suspected cytomegalovirus (CMV) infection during the first trimester.

Methods: All blood tests for CMV immunoglobulin M (IgM) done between 2008 and 2009 on pregnant women who were enrolled in the Maccabi Healthcare Services were retrieved from laboratory database. Immunoglobulin G (IgG) avidity was measured and women were classified according to the risk of acquiring CMV infection. For each patient, performance of amniocentesis and whether pregnancy came to term were recorded.

Results: Of 109,439 pregnant women evaluated during the study period, 76,712 (70.1%) were tested for CMV IgM, and 792 (1.03%) were found to be positive. Among women with positive IgM, only 205 (25.9%) underwent amniocentesis. When compared with women with negative CMV IgM, the rate of pregnancy cessation was doubled in women with positive CMV IgM (28.3% vs. 14.3%, P < 0.05) and mostly elevated in women with a high risk of acquiring CMV (42.3% pregnancy cessation). Among women with positive CMV IgM, those who did not undergo amniocentesis were more likely to abort than those who performed amniocentesis (35.6% vs. 7.3%, P < 0.05). 

Conclusions: More women with suspected CMV infection during the first trimester of pregnancy aborted before all means of detection were utilized to rule out or confirm fetal infection with CMV.

 

Background: The prevalence of major malformations in the general population is estimated at 5% of all live births. Prenatal diagnosis is an important scientific tool that allows reliable consultation and improves pregnancy outcome. In 2008, congenital malformations were the leading cause of death in Muslim infants and the second cause of death in Jewish infants in Israel. It is known that folic acid consumption prior to pregnancy decreases the rate of several fetal malformations.

Objectives: To assess the folic acid consumption rate and to characterize variables associated with its use among pregnant women attending a rural medical center. 

Methods: A cross-sectional observational study was conducted at our institution. Pregnant women in the second or third trimester of pregnancy or within 3 days postpartum were interviewed. The main variable measured was the use of folic acid. Demographic variables and the rate of prenatal testing were assessed. A secondary analysis of the population that reported no consumption of folic acid was carried out. 

Results: Out of 382 women who participated in the study, 270 (71%) reported consumption of folic acid. Using a multivariate analysis model, we found that maternal education, planning of pregnancy, and low parity were independent predictors of folic acid consumption. Women who were not consuming folic acid tended to perform fewer prenatal tests during pregnancy.

Conclusions: High maternal educational level, planning of pregnancy, and low parity are related to high consumption rates of folic acid. Women who were not taking folic acid performed fewer prenatal tests during pregnancy. 

Background: Abatacept acts as a co-stimulation modulator preventing activation of T cells. Although it is approved for the treatment of rheumatoid arthritis (RA), its effects on adaptive immune response have not been fully elucidated. 

Objectives: To observe, in a cohort study, based on a clinical practice setting, the variation of peripheral blood T cells, immunoglobulin levels, and autoantibodies in the serum of RA patients during abatacept therapy. 

Methods: Our study comprised 48 RA patients treated with abatacept. All clinical data were collected at baseline and after 3 months of treatment. Clinical and laboratory tests included erythrocyte sedimentation rate, C-reactive protein, 28-joint disease activity score, RF, anti-citrullinated protein antibody, total immunoglobulins, immunoglobulin A (IgA), immunoglobulin G (IgG), immunoglobulin M (IgM), and lymphocyte sub-population. 

Results: Total immunoglobulin serum levels significantly decreased after 3 months of treatment and correlated positively with disease activity both at baseline and after 3 months of abatacept treatment. A reduction of serum IgM, IgG, IgA and RF was also demonstrated. The absolute number and percentage of cytotoxic (CD8+) T cells significantly decreased after 3 months of abatacept treatment, in particular the percentage of cytotoxic (CD8+) T cells significantly decreased only in patients responding to the treatment.

Conclusions: Our results highlight a different role of abatacept in the modulation of the adaptive immune response in RA by the reduction of polyclonal B-cell activation and cytotoxic T cells. 

 

Background: The evidence on the use of dexamethasone implants in the treatment of Behçet’s disease (BD)-related uveitis is limited to a few cases. 

Objectives: To evaluate the efficacy of dexamethasone implants on ocular functional, morphological, and clinical parameters in BD patients with severe refractory uveitis. 

Methods: Five eyes from five BD patients were enrolled. A single intravitreal dexamethasone injection was applied to each eye. Best corrected visual acuity (BCVA), central macular thickness (CMT) assessed with optical coherence tomography, retinal vasculitis assessed by fluorescein angiography, vitreous haze score (Nussenblatt scale), intraocular pressure (IOP), and lens status (LOCS III, Lens Opacities Classification System III) were recorded at baseline and at 1, 3, and 6 month follow-up visits.

Results: At baseline, all eyes showed marked macular edema and 4/5 had concomitant active retinal vasculitis. Mean BCVA was increased from baseline at each control visit with a mean improvement of 0.26 ± 0.18 lines at 6 months follow-up. Mean CMT decreased from baseline at each control visit with a mean improvement at 6 months follow-up of 198.80 ± 80.08 µm. At the end of the study, none of the eyes showed macular edema and the mean CMT was 276.80 ± 24.94 µm. Retinal vasculitis resolved in all eyes. One eye experienced an IOP spike during treatment that resolved spontaneously, and one eye developed a clinically significant lens opacity at 6 months follow-up. 

Conclusions: Treatment with a dexamethasone implant in BD-uveitis and inflammatory macular edema was safe and effective as an additional treatment combined with systemic immunomodulatory drugs.

 

Background: Anti-glomerular basement membrane (GBM) antibody disease, or Goodpasture’s disease, is the clinical manifestation of the production of anti-GBM antibodies, which causes rapidly progressive glomerulonephritis with or without pulmonary hemorrhage. Anti-GBM antibody detection is mandatory for the diagnosis of Goodpasture’s disease either from the serum or kidney biopsy. Renal biopsy is necessary for disease confirmation; however, in cases in which renal biopsy is not possible or is delayed, serum detection of anti-GBM antibody is the only way for diagnosis.

Objectives: To assess the predictive value of positive anti-GBM antibodies in a clinical setting. 

Methods: Data from anti-GBM antibody tests performed at one medical center between 2006 and 2016 were systematically and retrospectively retrieved. We recruited 1914 patients for the study. Continuous variables were computed as mean ± standard deviation, while categorical variables were recorded as percentages where appropriate. Sensitivity and specificity of anti-GBM titers were calculated. Kaplan–Meyer analysis was performed, stratifying survival according to the anti-GBM antibody titers.

Results: Of the 1914 anti-GBM test results detected, 42 were positive, 23 were borderline, 142 were excluded, and 1707 results were negative. Male-to-female ratio was 1:1.2. Sensitivity of anti-GBM test was 41.2% while specificity was 85.4%. Concerning the Kaplan–Meyer analysis, overall survival was 1163.36 ± 180.32 days (median 1058 days). 

Conclusions: Our study highlights the lack of sensitivity of serological testing of anti-GBM titers. Comparing survival curves, the survival correlated with anti-GBM titer only in a borderline way. Because highly sensitive bioassays are not routinely used in clinics, renal biopsy is still pivotal for Goodpasture’s disease diagnosis.

 

Fevers recurring at a nearly predictable rate every 3–8 weeks are the signature symptom of periodic fever, aphthous stomatitis, pharyngitis, cervical adenitis (PFAPA) syndrome, an acquired autoinflammatory disorder which recurs in association with at least one sign among aphthous stomatitis, pharyngitis, and/or cervical lymph node enlargement without clinical signs related to upper respiratory airways or other localized infections. The disease usually has a rather benign course, although it might relapse during adulthood after a spontaneous or treatment-induced resolution in childhood. The number of treatment choices currently available for PFAPA syndrome has grown in recent years, but data from clinical trials dedicated to this disorder are limited to small cohorts of patients or single case reports. The response of PFAPA patients to a single dose of corticosteroids is usually striking, while little data exist for treatment with cimetidine and colchicine. Preliminary interesting results have been published with regard to vitamin D supplementation in PFAPA syndrome, while inhibition of interleukin-1 might represent an intriguing treatment for PFAPA patients who have not responded to standard therapies. Tonsillectomy has been proven curative in many studies related to PFAPA syndrome, although the evidence of its efficacy is not widely shared by different specialists, including pediatricians, rheumatologists and otorhynolaryngologists.

Background: The debate continues regarding the best way to manage partial anterior cruciate ligament (ACL) tears.

Objectives: To prospectively compare the clinical outcomes of remnant-preserving augmentation (RPA) and double-bundle reconstruction (DBR) in patients with ACL tears.

Methods: In this prospective study, we included 13 cases of RPA and 30 cases of DBR with a follow-up period of 6 months, 12 months and 24 months. We clinically compared the preoperative and postoperative range of motion, Knee Society Score (KSS), Visual Analog Scale (VAS), Lysholm score, Tegner activity score, Short Form Health Survey (SF-36), thigh and calf circumference and anterior translation (Using the KT-1000 knee arthrometer). 

Results: There were no significant differences in Lysholm score, Tegner score, VAS or KSS within the two groups at any time. The KT-1000 arthrometer results were higher in the RPA group at 6 months than in the DBR group; however, it did not reach statistical significance. 

Conclusions: We found no significant differences between the two specific groups leading us to believe that RPA may play a role in reconstruction when only a single bundle is injured.

 

Background: Standardization of the dietetic care process allows for early identification of malnutrition and metabolic disorders, interdisciplinary collaboration among the medical team, and improved quality of patient care. Globally, dietitians are adopting a nutrition care model that integrates national regulations with professional scope of practice. Currently, Israel lacks a standardized dietetic care process and documentation terminology.

Objectives: To assess the utilization of a novel sectoral documentation system for nutrition care in Israel.

Methods: Seventy dietitians working in 63 geriatric facilities completed an online training program presenting the proposed patient-sectoral-model. Training was followed by submission of sample case studies from clinical practice or completion of a case simulation. Application of the proposed model was assessed by measuring the frequency participants implemented different sections of the model and responses to an approval questionnaire.

Results: Fifty-four participants (77%) provided completed cases. Over 80% of participants reported each step of the proposed dietary care process with 100% reporting the “nutrition diagnosis”. Fifty-one dietitians (72.8%) completed the approval survey with the section on nutrition diagnosis receiving a highly favorable response (95%), indicating that the new documentation system was beneficial. Over 80% of participants rated the model useful in clinical practice.

Conclusions: A sectoral approach for documenting dietetic care may be the ideal model for dietitians working in specific patient populations with the potential for improving interdisciplinary collaboration in patient care.

Obstetric antiphospholipid syndrome (Obs-APS) is one of the most commonly identified causes of recurrent pregnancy loss and its accurate diagnosis is a requirement for optimal treatment. Some patients do not fulfill the revised Sapporo classification criteria, the original APS classification criteria, and are considered to be non-criteria Obs-APS. In these patients with non-criteria, there is controversy about their inclusion within the spectrum of APS and eventually their treatment as having Obs-APS. A subset of patients may also have clinical characteristics of Obs-APS even though lupus anticoagulant (LA), anticardiolipin antibodies, and anti-β2-glycoprotein I (aβ2GPI) antibodies are consistently negative. These patients are recognized as seronegative Obs-APS.

We reviewed evidence of non-criteria Obs-APS and discuss a case of a woman with a diagnosis of active systemic lupus erythematosus (SLE) and non-criteria Obs-APS with four consecutive pregnancy losses. After an accurate diagnosis the patient received prenatal counseling and benefited from the optimal treatment of Obs-APS that led to a successful pregnancy. The applicability of this successful experience about outcomes in women with non-criteria, or seronegative, Obs-APS is also evaluated.
