Eculizumab therapy and complement regulation in a case of resistant catastrophic antiphospholipid syndrome.

Catastrophic antiphospholipid syndrome (CAPS) is a life-threatening form of antiphospholipid syndrome characterised by diffuse arterial and venous thrombosis, in the presence of positive antiphospholipid antibodies. The multiple sites of thrombosis in small, medium and large vessels progress to multiorgan failure, accounting for the high mortality rate associated with CAPS. Unregulated complement activation is increasingly recognised as critical to the pathogenesis of CAPS. Early diagnosis is essential to initiate prompt life-saving treatment with the triple therapy of anticoagulation, immunosuppression and either plasmapheresis or intravenous immunoglobulin. Among other immunosuppressive agents, eculizumab, a complement inhibitor has demonstrated efficacy in treatment-resistant cases.We report an instructive case of a woman presenting with both clinical and laboratory findings consistent with primary CAPS, resistant to initial treatment and responsive to eculizumab, with emphasis on genetic testing and implications for future therapy.

Recommendations for weight management in osteoarthritis: A systematic review of clinical practice guidelines.

Objective: While targeting obesity is central to osteoarthritis management, recent meta-analyses demonstrate only modest effects of weight loss on symptoms, and little on structure. The World Health Organisation recommends that effective management of obesity include prevention of weight gain, weight maintenance and weight loss. Therefore, we systematically reviewed the recommendations and approaches for management of obesity in clinical practice guidelines (CPGs) for osteoarthritis. Design: Nine databases were searched (01.01.2010-15.03.2022) to identify guidelines informing the non-pharmacological management of osteoarthritis. Three reviewers appraised guidelines according to the AGREE II instrument, and independently extracted data on their characteristics. One author extracted and summarised guideline recommendations on weight management. This systematic review is registered on PROSPERO (CRD42021274195). Results: Of the included fifteen CPGs (median AGREE II domain score 78.7%), weight loss was recommended for knee (12 of 13) and hip (10 of 11) but not hand (0 of 4) osteoarthritis. Combination approaches of diet and/or exercise were recommended for overweight or obese individuals in knee (8 of 12) and hip (4 of 10) osteoarthritis. Two guidelines specified ≥5% weight loss. One guideline specified strategies for maintenance of lost weight; none specifically recommended preventing weight gain. There was discordance between strength of recommendation for weight loss and level of evidence (3 of 15). Conclusion: Most CPGs for knee and hip osteoarthritis recommend weight loss to manage obesity in osteoarthritis. As steady weight accumulation is common in adults, preventing weight gain should also be considered as it is a missed opportunity to improve outcomes in osteoarthritis.

Interprofessional learning about medication safety.

BACKGROUND: Safe medication management requires collaboration between health professionals. APPROACH: A mixed academic and clinician team co-designed and co-facilitated a 2-h interprofessional medication safety workshop, covering medication history taking, perioperative medication management, discharge planning, incident review and dosing and administration calculations. Three workshop sessions were delivered across three sites during September 2019 at a large metropolitan healthcare network. Senior nursing, medical and pharmacy students were invited to participate in the workshops and evaluation. EVALUATION: We evaluated satisfaction, learning experience and perceived clinical application for medical, pharmacy and nursing students. Surveys were conducted immediately after each workshop and at 4 weeks. Quantitative data was analysed descriptively and qualitative data analysed using thematic analysis. Forty-five students participated in the evaluative component of the workshops. Mean student response scores demonstrated a high level of satisfaction with the workshop's relevance and utility to their learning. Students expressed strong agreement that the workshop promoted communication across professions for medication safety. Analysis of the qualitative data identified seven key themes, with consistently positive responses provided in each: interactions within the interprofessional team; recognising the importance of teams; learning the process of medication use; acknowledging and working with difference; role playing; thinking patient safety; and authenticity. IMPLICATIONS: A 2-h interprofessional workshop about medication safety provided positive learning experiences with high satisfaction to medical, nursing and pharmacy students, and had strong perceived applicability to their future clinical practice.
