Novel cell-free and concentrated ascites reinfusion therapy (KM-CART) is easy to use, safe and applicable for refractory ascites. We can get the full amount of ascites, filtrate, and concentrate in a short time. KM-CART can be applied as palliative care for dying patients including patients with massive malignant ascites. Some patients who underwent repeated KM-CART survived longer than those who did not repeat the therapy. The aim of this study was to identify the type of patients with ascites for whom KM-CART would be effective and candidates for repeated KM-CART. In this retrospective cohort observational study, we examined 123 CART processes performed on 58 patients with refractory ascites. Data were collected before and after processing of the ascites. We compared two groups; patients who underwent KM-CART = 5 times and those who underwent this process = 4 times. Age, disease, benign or malignant status of the disease, the amount of ascites, concentrations of total protein (TP) and albumin (Alb) and their amounts in the original ascites and the filtered and concentrated ascitic fluid and the recovery ratio of TP and Alb were determined. No significant difference was observed between the two groups in age, disease, amount of ascites, and the recovery ratio of TP and Alb. Significant differences were observed in the amounts of TP and Alb in the original ascites and the filtered and concentrated ascitic fluid. Patients who underwent KM-CART = 5 times had higher Alb levels in the original ascites than those who underwent this therapy = 4 times. Patients with higher Alb concentrations in the original ascites could be candidates for repeated KM-CART. [ABSTRACT FROM AUTHOR]

We report a case of suspected pseudo-elevation of serum creatinine in a patient with rheumatoid arthritis, whose blood sample was obtained from his right cubital vein immediately after the intra-articular injection of 0.67 mg of a pharmaceutical preparation of dexamethasone (Decadron) containing creatinine as a buffer into his right wrist joint to alleviate arthralgia. The 61-year-old male patient, who had been treated for rheumatoid arthritis, was referred to our outpatient clinic by his family doctor because of sudden elevation of his serum creatinine, which hitherto had been normal. Acute kidney injury (AKI) was suspected, but his medical history, physical examinations, and laboratory findings did not support the diagnosis of AKI. The preserved serum sample obtained when the elevation of his serum creatinine was reported was examined and revealed that the serum concentration of cystatin C was normal, but the serum concentration of creatinine measured with high-performance liquid chromatography method was elevated to a degree consistent with the serum creatinine concentration measured with enzymatic method. Accordingly, we predicted the possibility that creatinine contained in Decadron as a buffer was included in the measurement of his intrinsic serum creatinine. To test this hypothesis, the creatinine concentration of serum samples from another patient with known amounts of added Decadron were measured, and the additive effect of the extrinsic creatinine in the measurement of serum creatinine concentration was confirmed. These findings clearly suggest that we should consider the influence of extrinsic creatinine as an inactive ingredient in the measurement of serum creatinine.

A 17-year-old high school boy was admitted to our hospital because of hypertension. Doppler ultrasound of the renal arteries and 3D-CT angiography showed a stenosis of the right renal artery, which was pushed against the aorta by the right crus of the diaphragm. He underwent aortography and selective renal arteriography. His right renal artery originated from the aorta at a higher level than the left renal artery, between the celiac artery and the superior mesenteric artery. Renal arteriography confirmed a 50% reduction in diameter (stenosis) of the proximal right renal artery entrapped by the right diaphragmatic crus. This pathology, unlike common renal artery stenosis, sometimes requires surgical decompression or an aortorenal bypass graft, because renal angioplasty with stenting is reported to be at risk of complication by a fracture of the stent. However, the patient rejected surgical decompression for fear of deterioration of his athletic ability. Therefore we decided to follow up his blood pressure and renal size by ultrasound every six months. Renovascular hypertension caused by diaphragmatic entrapment is a very rare disease. The diagnosis may be overlooked easily at angiography if optimal views are not obtained. It is important to display images of the renal arteries, the celiac artery and the superior mesenteric artery in both inspiration and expiration.
