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.

 

Autoimmune rheumatic diseases (ARD) affect mainly young women during their reproductive years. Fertility is usually not diminished but the time it takes to conceive is usually longer. Factors related to an ARD or to its treatment are responsible for this effect. In addition, contraception counseling is required to prevent negative fetal outcome and exacerbation of disease symptoms. In recent years, advances in therapies, clarification of risk factors for adverse pregnancy outcomes, and a multidisciplinary approach have vastly improved obstetric management, increasing the possibility of successful pregnancy with a high likelihood of favorable outcome.

Background: Dedicated, organ-specific screening clinics have been shown to significantly reduce cancer morbidity and mortality.

Objectives: To establish a dedicated clinic for Clalit Health Service patients at high risk for hereditary gastrointestinal cancer and to provide them with clinical and genetic counseling, diagnostic screening and follow–up.

Results: During the 3 years of the clinic's activity, 634 high risk families, including 3804 at-risk relatives, were evaluated. The most common conditions were hereditary colorectal syndromes, Lynch syndrome (n=259), undefined young-onset or familial colorectal cancer (n=214), familial adenomatous polyposis (n=55), and others (n=106). They entered follow-up protocols and 52 underwent surgical procedures.

Conclusions: Consistent public and professional education is needed to increase awareness of hereditary colorectal cancer and the possibility of family screening, early diagnosis and therapy. The public health services – i.e., the four health management organizations – should provide genetic testing for these patients who, at present, are required to pay for almost all of these available but costly tests. Dedicated colorectal surgical units are needed to provide the specialized therapeutic procedures needed by patients with familial colorectal cancer. Our future plans include adding psychosocial support for these at-risk patients and their families as well as preventive lifestyle and dietary intervention. 

Background: Primary pulmonary hypertension is a rare disorder, characterized by progressive pulmonary hypertension and right heart failure. It may be familial or sporadic. Mutations in bone morphogenetic protein receptor II (BMPR2), a member of the transforming growth factor-beta receptor superfamily of receptors, underlie many cases of the disorder.

Objectives: To perform molecular analysis of a patient with familial PPH[1] and provide her and her family with suitable genetic counseling.

Methods: DNA was extracted from 10 ml whole blood, and the BMPR2 gene was screened for mutations. Individual exons were amplified by polymerase chain reaction and sequenced. Mutation confirmation and molecular characterization of additional family members was performed using restriction enzyme analysis followed by appropriate genetic counseling.

Results: We identified a novel T to C missense mutation expected to result in substitution of arginine for a conserved cysteine in the ligand-binding domain of BMPR2. Screening of family members demonstrated the presence of the mutation in the father and a younger asymptomatic sister of the index patient.

Conclusions: Molecular diagnosis in PPH allows for identification of at-risk family members and raises the option of earlier diagnosis and possibly instituting earlier treatment in affected individuals. However, molecular screening of asymptomatic family members raises difficult ethical questions that can only be resolved by conducting large multicenter prospective studies in BMPR2 carriers.

The etiology of inflammatory bowel diseases, Crohn’s disease and ulcerative colitis, is uncertain. Studies of specific environmental factors and immune dysfunction have provided limited insight into disease pathogenesis. There is ample evidence that these diseases are in part the result of genetic predisposition. The early search for candidate genes focused on genes involved in the regulation of immune function.

Recent genome wide searches reported several susceptibility loci for Crohn’s disease and ulcerative colitis. The recent identification of the IBD1 gene (NOD2) with mutations that are associated with susceptibility to Crohn’s disease will have a major impact on the understanding of the genetics of this disease.
 

Background: The more patients know about their medications the higher their compliance with drug therapy, reflecting an effective communication between health professionals and their patients. Numerous studies on this subject have been published, but none has been conducted in Israel.

Objectives: To evaluate patients’ perceptions of drug counseling by health professionals – the prescribing physician and dispensing pharmacist – and to determine whether there is a difference in the patient’s perception according to his or her place of birth and mother tongue.

Methods: A total of 810 patients were interviewed following receipt of their medications from in-house pharmacies at two community clinics of Israel’s largest sick fund. Each patient was interviewed in his or her mother tongue according to a constructed questionnaire, which included the patient’s demographic background, type of medications received, the patient’s perceptions of drug counseling given by both the physician and the pharmacist, and the patient’s perception of non-prescription drug counseling given by the dispensing pharmacist.

Results: Of the 810 patients enrolled in this study, 32% received three or more medications at each physician visit. The main therapeutic classes of medications prescribed and dispensed were for neurological disorders, cardiovascular diseases, gastrointestinal problems and respiratory diseases. While 99% of the patients claimed that they knew how to use their medications, only 96% reported receiving an explanation from either physician or pharmacist. The quality of counseling, as evaluated by the patients, was ranked above average for 75% of the consultations with the prescribing physician and 63% with the dispensing pharmacist.

Conclusions: Although few conclusions can be drawn from this study based on the initial statistical analysis of the data, the major findings were that patients value highly the counseling they receive and that 99% believe they have the requisite knowledge for using their medications. Compared to the international literature, our results – based on the patients' perceptions – indicate that counseling by pharmacists is a common and well-accepted activity in Israel and occurs at a high rate.
