RESUMO

Teratogenic medications are often prescribed to women of childbearing age with autoimmune diseases. Literature suggests that appropriate use of contraception among these women is low, potentially resulting in high-risk unintended pregnancies. Preliminary review in our clinic showed suboptimal documentation of women's contraceptive use. We therefore designed a quality improvement initiative to target three process measures: documentation of contraception usage and type, contraception counselling and provider action after counselling. We reviewed charts of rheumatology clinic female patients aged 18-45 over the course of 10 months; for those who were on teratogenic medications (methotrexate, leflunomide, mycophenolate and cyclophosphamide), we looked for evidence of documentation of contraception use. We executed multiple plan-do-study-act (PDSA) cycles to develop and evaluate interventions, which centred on interprofessional provider education, modification of electronic medical record (EMR) templates, periodic provider reminders, patient screening questionnaires and frequent feedback to providers on performance. Among eligible patients (n=181), the baseline rate of documentation of contraception type was 46%, the rate of counselling was 30% and interventions after counselling occurred in 33% of cases. Averaged intervention data demonstrated increased provider performance in all three domains: documentation of contraception type increased to 64%, counselling to 45% and provider action to 46%. Of the patients with documented contraceptives, 50% used highly effective, 27% used effective and 23% used ineffective contraception methods. During this project, one unintentional pregnancy occurred in a patient on methotrexate not on contraception. Our interventions improved three measures related to contraception counselling and documentation, but there remains a need for ongoing quality improvement efforts in our clinic. This high-risk population requires increased provider engagement to improve contraception compliance, coupled with system-wide EMR changes to increase sustainability.

RESUMO

T lymphocytes circulate between the blood, tissues, and lymph. These T cells carry out immune functions, using the C-C chemokine receptor 7 (CCR7) and its cognate ligands, CCL19 and CCL21, to enter and travel through the lymph nodes. Distinct roles for each ligand in regulating T lymphocyte trafficking have remained elusive. We report that in the human T cell line HuT78 and in primary murine T lymphocytes, signaling from CCR7/CCL19 leads to increased expression and phosphorylation of extracellular signal-regulated kinase 5 (ERK5) within eight hours of stimulation. Within 48-72 h we observed peak levels of endothelial differentiation gene 1 (EDG-1), which mediates the egress of T lymphocytes from lymph nodes. The increased expression of EDG-1 was preceded by up-regulation of its transcription factor, Krüppel-like factor 2 (KLF-2). To determine the cellular effect of disrupting ERK5 signaling from CCR7, we examined the migration of ERK5(flox/flox)/Lck-Cre murine T cells to EDG-1 ligands. While CCL19-stimulated ERK5(flox/flox) naïve T cells showed increased migration to EDG-1 ligands at 48 h, the migration of ERK5(flox/flox)/Lck-Cre T cells remained at a basal level. Accordingly, we define a novel signaling pathway that controls EDG-1 up-regulation following stimulation of T cells by CCR7/CCL19. This is the first report to link the two signaling events that control migration through the lymph nodes: CCR7 mediates entry into the lymph nodes and EDG-1 signaling controls their subsequent exit.

RESUMO

Interstitial lung disease (ILD) is a unique group of lung diseases that can be associated with inflammatory conditions, such as polymyositis-dermatomyositis (PM-DM). Presentation of PM-DM with ILD is not uncommon but clinical and radiological features can be similar to other conditions (e.g. atypical pneumonia) and can be challenging to diagnose. Delayed diagnosis of PM-DM can be associated with progression of pulmonary involvement and potentially increase morbidity. We report a patient presenting with pulmonary symptoms who had positive anti-Jo-1 antibodies and cryptogenic organizing pneumonia features on biopsy, which is a rare reported finding.
