Objective Allergic reactions are a severe complication of plasma exchange (PEx). Few reports have analyzed allergic reactions during PEx using fresh-frozen plasma (FFP) as a replacement solution. We therefore clarified the relationship between risk and exacerbation factors that lead to the onset of PEx-related allergic reactions, particularly PEx, using FFP, and examined whether or not allergic reactions were predictable. Methods This retrospective study included 88 consecutive patients who underwent PEx with FFP as a replacement solution at Kitasato University Hospital. The patients were grouped according to the presence of allergic reactions and compared. Data were analyzed using the χ2 test, Mann-Whitney U test, and a binomial logistic analysis. Statistical analyses were performed using EZR software program, version 1.54, with p <0.05 considered statistically significant. Results There were 44 allergic reaction cases. The average time to the onset of an allergic reactions was 63.5 (45-93) min. The allergic reaction-onset group had significantly higher average albumin (Alb) levels than did the non-allergic reaction-onset group. The binomial logistic analysis identified Alb levels as independent risk factors for allergic reactions. The receiver operating characteristic analysis identified an Alb level ≥3.4 g/dL as a risk factor for allergic reactions (area under the curve: 0.731; 95% confidence interval: 0.622-0.84). Conclusion Allergic reaction onset occurred approximately one hour after PEx initiation in the critical period. A serum Alb level ≥3.4 g/dL was identified as a risk factor for predicting allergic reactions. Patients with Alb levels ≥3.4 g/dL at the first PEx should be monitored for allergic reaction symptoms.

Objective The present study was undertaken to determine the characteristics and outcome of in-hospital cardiac arrests and the effectiveness of BVM ventilation with airway adjuncts including the oropharyngeal airways and nasopharyngeal airways. Methods Information about in-hospital cardiac arrests over a period of 6 years was retrospectively collected, and the effectiveness of BVM ventilation with airway adjuncts was analyzed using a multivariate logistic regression model. Results During the study period, 105 (male, n=70; age, 68.6±14.2 years) cardiac arrests occurred, of which 95.2% developed among inpatients and 21.0% of them were witnessed. The initial rhythm of cardiac arrests was pulseless electrical activity in 63.8% (67/105) and respiratory failure (44.8%) was the most common cause. Overall, a return of spontaneous circulation occurred in 76.2% of in-hospital cardiac arrests, 31.4% survived to discharge, and the neurological outcome was good (cerebral performance category-1) in 66.7% of them. Bag-valve-mask ventilation with airway adjuncts improved the neurological outcome (OR 3.52, 95%CI 1.07, 11.5). Conclusion Bag-valve-mask ventilation with airway adjuncts improved neurological outcomes.

Lecithin cholesterol acyltransferase (LCAT) is a lipid-modification enzyme that catalyzes the transfer of the acyl chain from the second position of lecithin to the hydroxyl group of cholesterol (FC) on plasma lipoproteins to form cholesteryl acylester and lysolecithin. Familial LCAT deficiency is an intractable autosomal recessive disorder caused by inherited dysfunction of the LCAT enzyme. The disease appears in two different phenotypes depending on the position of the gene mutation: familial LCAT deficiency (FLD, OMIM 245900) that lacks esterification activity on both HDL and ApoB-containing lipoproteins, and fish-eye disease (FED, OMIM 136120) that lacks activity only on HDL. Impaired metabolism of cholesterol and phospholipids due to LCAT dysfunction results in abnormal concentrations, composition and morphology of plasma lipoproteins and further causes ectopic lipid accumulation and/or abnormal lipid composition in certain tissues/cells, and serious dysfunction and complications in certain organs. Marked reduction of plasma HDL-cholesterol (HDL-C) and corneal opacity are common clinical manifestations of FLD and FED. FLD is also accompanied by anemia, proteinuria and progressive renal failure that eventually requires hemodialysis. Replacement therapy with the LCAT enzyme should prevent progression of serious complications, particularly renal dysfunction and corneal opacity. A clinical research project aiming at gene/cell therapy is currently underway.
