Despite the established association between chronic idiopathic/spontaneous urticaria (CIU) and presence of antinuclear antibodies (ANAs), the prevalence of autoimmune comorbidities in this population has not been analyzed. Here, we aim to identify clinical and laboratory manifestations associated with ANA-positive CIU. ANA-positive patients were identified via electronic data capture from the electronic patient record database of Leumit Health care Services (LHS) of Israel. Patient characteristics, medical histories, and details of diagnostic workup, medical treatment, and follow-up were retrieved by performing a chart review of electronic patient records (EPRs). The prevalence of target diseases among ANA(+) CIU(+), ANA(+) CIU(-), and ANA(-) CIU(+) patients was calculated. A total of 91 ANA(+) CIU(+), 3131 ANA(+) CIU(-), and 478 ANA(-) CIU(+) patients were identified. The ANA(+) CIU(+) group was characterized by higher prevalence of Sjögren's syndrome (SS)-A 52 antibodies (Ab) (7.7% versus 2.4%; p = 0.008), SS-A 60 Ab (11% versus 2.8%; p = < 0.001), and SS-B Ab (14.3% versus 3.2%; p < 0.001), compared with ANA(-) CIU(+) group. Additionally, ANA(+) CIU(+) patients were more likely to be diagnosed with thyroid autoimmune diseases, higher C-reactive protein (6.4 ± 10.3 versus 4.1 ± 8.8 mg/L; p = 0.027), and more profound basopenia (0.04 ± 0.09 versus 0.15 ± 0.11 cell/mm(3); p < 0.001) than ANA(-) CIU patients. More ANA(+) CIU(+) patients were resistant to four-fold standard licensed doses of antihistamines than ANA(-) CIU(+) patients [11 (12.1%) versus 29 (6.1%); p = 0.046]. ANA-positive CIU is characterized by higher prevalence of SS-A 52, SS-A 60, and SS-B antibodies and poorer clinical response to antihistamine medications.

Physicians who opt to treat UTI in postmenopausal women empirically should consider prescribing drugs other than fluoroquinolones. Concomitant longitudinal surveillance of both antibiotic utilization patterns and uropathogen resistance rates should become routine practice in this managed-care organization.

An estimated prevalence of AA among an Israeli population was ∼0.8%. The novel finding of our study was the high prevalence of food allergy and CSU in patients with AA.

Ambulatory schizophrenia patients without a concomitant infectious/inflammatory process exhibit altered thermoregulation manifested by a substantial (about 0.2 C) and significantly lower oral temperature compared to healthy comparison subjects as well as a potential exaggerated increase in oral temperature during transitory infectious/inflammatory processes. The relevance of these phenomena to the pathophysiology of schizophrenia as well as the potential immune-mediated pathologies in schizophrenia merit further investigation.

Suboptimal adherence to the guidelines resulted in a significant and avoidable waste of the health plan's resources in both drugs and money.

AimsPrior authorization (PA), the requirement of physicians to obtain pre-approval as a prerequisite for coverage, may decrease drug utilization via a 'sentinel effect', a decrease in utilization caused by external review of prescribing. The purpose of this study was to assess the affect a PA restriction had on the utilization patterns of cefuroxime tablets in a managed care organization (MCO) in Israel. MethodsPhysician prescribing patterns were evaluated by conducting a retrospective drug utilization analysis. Data were derived from the electronic patient records of the MCO studied. All prescriptions for solid state antibiotics for patients diagnosed with an infectious disease written during three parallel 3-month segments, before, during and after a PA restriction for cefuroxime was enforced, were included. Frequency and proportion of antibiotic prescriptions for cefuroxime tablets, distribution of infectious diseases treated with cefuroxime, and the request rejection rate when PA was required were calculated. ResultsPrescriptions for cefuroxime declined from 5538 prescriptions (8.0% of eligible antibiotic prescriptions, 95% CI 7.8, 8.2) in the initial period to 1036 (1.2%, 95% CI 1.1, 1.3) during the PA period, rising to 3961 (4.3%, 95% CI 4.2, 4.4) in the post-PA period. Changes in the distribution of diseases treated with cefuroxime during the PA stage tended to regress after revocation to those observed in the pre-PA period. The rejection rate was found to be 8.5% (95% CI = 6.9, 10.1). ConclusionsThe implementation of a prior authorization requirement for cefuroxime tablets markedly reduced the use of this drug, probably due to a 'sentinel effect'.
