Anti-lipid therapy and risk factor management for triglyceridaemia-induced acute pancreatitis.

BACKGROUND: Pancreatitis secondary to hypertriglyceridaemia is rare, accounting for less than 5% of pancreatitis presentations. We reviewed our institutional experience with triglyceridaemia induced acute pancreatitis to report the clinical presentation, patient demographics and clinical management. METHODS: The Acute Surgical Unit database at a high-volume general surgical referral centre was queried to identify cases of acute pancreatitis secondary to hypertriglyceridaemia between 2016 and 2019. Patient demographics, clinical manifestations, biochemical derangements and treatment regimens were analysed. Current related literature was reviewed. RESULTS: There were 496 presentations for acute pancreatitis of which 14 presentations (2.8%), amongst 12 patients were due to hypertriglyceridaemia. The mean triglyceride level at presentation was 92.46 (standard deviation 46.9) mmol/L. Ten patients (83%) had poorly controlled type 2 diabetes. All patients were managed using conservative therapy combined with a restricted fat diet and commenced on long-term anti-lipid therapy to manage associated risk factors. In addition, 10 patients received an insulin infusion and one patient received insulin infusion, plasmapheresis and heparin infusion in combination. The median length of hospital stay was 5.5 (range 3-13) days. Two patients (16%) developed a recurrent episode related to non-compliance to medical therapy. CONCLUSION: Hypertriglyceridaemia is a rare cause of acute pancreatitis. Successful management involves the treatment of acute pancreatitis in conjunction with long-term anti-lipid therapy and optimisation of associated risk factors.

Case of severe acute lupus myocarditis and multiple-organ failure.

We report a case of severe lupus myocarditis with rapid, acute deterioration to cardiogenic shock and multiorgan failure, highlighting the importance of early identification and treatment of acute presentations in patients with systemic lupus erythematosus. A 31-year-old woman with previously diagnosed subacute cutaneous lupus erythematosus initially presented with abdominal pain and frank per-rectal bleeding. She deteriorated rapidly with type 1 respiratory failure and acute kidney injury requiring dialysis secondary to acute cardiac failure with a prolonged intensive care unit admission, over a month. A significantly elevated troponin, global hypokinesia on echocardiogram and normal coronary artery angiogram and cardiac MRI lead to the diagnosis of acute lupus myocarditis as the cause for the cardiogenic shock. She was treated with high-dose corticosteroids and eventually made a full recovery, with cardiac function returning to normal.

Impact of non-traditional phosphate binders and cinacalcet on haemodialysis patient biochemistry, pill burden and cost.

AIM: The Australian Pharmaceutical Benefits Scheme (PBS) commenced cost subsidization for haemodialysis patients of sevelamer in December 2007, cinacalcet in July 2008 and lanthanum in May 2009. To determine the impact of PBS listing of these medications, we performed a single centre cross-sectional, longitudinal study. METHODS: Dialysis parameters and biochemistry were prospectively collected at 6 monthly intervals for all prevalent haemodialysis patients from October 2007 to April 2010. Medications prescribed to manage chronic kidney disease mineral and bone disorder were recorded. Univariate regression analysis was undertaken for each variable against time. RESULTS: Patient numbers ranged from 87 to 114 in each period. At baseline, mean age was 68.8 ± 14.3 years, 71% male, 15.1 ± 3.5 haemodialysis hours/week and urea reduction ratio 71.9 ± 9.8%. These variables were unchanged over time. The use of sevelamer, cinacalcet and lanthanum increased (P < 0.001). There was a decrease in the use of aluminium- and calcium-based phosphate binders (P < 0.001) but no change in the use of magnesium based phosphate binders (P = 0.09) or calcitriol (P = 0.11). Serum phosphate (P = 0.13) and parathyroid hormone (PTH) (P = 0.87) were unchanged. Mean 'bone pill' burden fell from 60.3/week to 51.9/week (P = 0.02). Mean pill cost increased from Australian dollars (AUD) 12.85/patient per week to AUD 59.85/patient per week (P < 0.001). CONCLUSION: The PBS subsidization of sevelamer, cinacalcet and lanthanum has changed prescribing patterns, although serum phosphate and PTH remain unchanged. These changes have been at an additional cost of AUD 2444/patient per year. Data to address clinical end-points of mortality and hospitalization is needed to determine if the cost of these newer agents is warranted.
