Novel and highly reliable leak check tests for drop- and external pressure-type cell-free and concentrated ascites reinfusion therapy.

INTRODUCTION: For safe management of cell-free and concentrated ascites reinfusion therapy (CART), a highly reliable leak test for detecting ascites filter damage is essential. However, such a test has not been established for drop-type CART. METHODS: We devised two novel leak tests for drop- and external pressure-type CART, manual or pump pressurization methods, using high-pressure loading and pressure monitoring, and investigated their reliability. RESULTS: Both methods could easily load and maintain sufficiently high pressure (>400 Torr) on the hollow fibers for 2 min. No result deviation was noted between different operators. The pressure drops in both methods were identical and significantly lower than those in the leak test using a special CART machine, the e-CART. CONCLUSION: The reliability of our revised leak test is equivalent to that of the automatic leak test of e-CART. These highly reliable leak tests may contribute to safety in patients undergoing drop- and external pressure-type CART.

Candida albicans and Staphylococcus lugdunensis superinfection of liver cysts in a patient with autosomal dominant polycystic kidney disease under prednisolone treatment.

We report a case of superinfection of liver cysts caused by Candida albicans and Staphylococcus lugdunensis in a patient with autosomal dominant polycystic kidney disease. A 69-year-old man with chief complaints of headache and blurred vision was admitted to the former institution for the evaluation of suspected temporal arteritis. He was prescribed oral prednisolone (55 mg/day) as a preemptive treatment; however, he became febrile and presented with bilateral flank pain during prednisolone tapering. Blood culture revealed fungemia as a result of Candida famata infection; thus, micafungin treatment was started. Thereafter, recrudescence of the C-reactive protein level ensued. Then a cyst infection as visualized on magnetic resonance imaging led to cyst aspiration sclerotherapy. Cyst aspirate culture revealed the presence of C. albicans in one of the cysts and S. lugdunensis in two of the cysts. The patient was clinically stabilized with an additional 3 weeks of antibiotic and antifungal drug administration.

Verification of serum albumin elevating effect of cell-free and concentrated ascites reinfusion therapy for ascites patients: a retrospective controlled cohort study.

Cell-free and concentrated ascites reinfusion therapy (CART) is frequently used to treat refractory ascites in Japan. However, its efficacy remains unclear. This controlled cohort study verified the serum albumin elevating effect of CART by comparisons with simple paracentesis. Ascites patients receiving CART (N = 88) or paracentesis (N = 108) at our hospital were assessed for the primary outcome of change in serum albumin level within 3 days before and after treatment. A significantly larger volume of ascites was drained in the CART group. The change in serum albumin level was +0.08 ± 0.25 g/dL in the CART group and -0.10 ± 0.30 g/dL in the paracentesis group (P < 0.001). The CART - paracentesis difference was +0.26 g/dL (95%CI +0.18 to +0.33, P < 0.001) after adjusting for potential confounders by multivariate analysis. The adjusted difference increased with drainage volume. In the CART group, serum total protein, dietary intake, and urine volume were significantly increased, while hemoglobin and body weight was significantly decreased, versus paracentesis. More frequent adverse events, particularly fever, were recorded for CART, although the period until re-drainage was significantly longer. This study is the first demonstrating that CART can significantly increase serum albumin level as compared with simple paracentesis. CART represents a useful strategy to manage patients requiring ascites drainage.
