    ABSTRACT: We report a case of a 66-year-old patient with paraquat intoxication resulting in the requirement for hemoperfusion, hemodialysis, and plasma exchange. His initial serum paraquat level was 0.24 µg/mL (0.0–0.1 µg/mL). Activated charcoal (50 g) was administered orally, and high-dose N-acetylcysteine (150 mg/kg) was administered intravenously. In addition, immediate 4 h hemoperfusion was also performed for three consecutive days after admission. Hemodialysis was started on the 4th day after admission because of uremia. On the 9th day after admission, laboratory findings demonstrated hemolytic uremic syndrome (HUS): microangiopathic hemolytic anemia (MAHA), thrombocytopenia, elevated reticulocyte count, and lactate dehydrogenase (LDH). Plasma exchange was performed three times consecutively. Anemia and thrombocytopenia were improved, and LDH was normalized after plasma exchange. Urine output increased to 2240 mL/day on the 18th day after admission, and hemodialysis was discontinued. He is currently being observed at our follow-up clinic without renal impairment or pulmonary dysfunction for 1.5 years since discharge. We should suspect paraquat-associated HUS when thrombocytopenia and anemia are maintained for a long time after paraquat intoxication. J. Clin. Apheresis, 2013. © 2013 Wiley Periodicals, Inc.

    ABSTRACT: Abstract A 56-year-old Korean man visited to emergency room due to paroxysmal flaccid paralysis in his lower extremities. There was no family or personal history of periodic paralysis. His initial potassium levels were 1.8 mmol/L. The patient had been taking Salicornia herbacea for the treatment of diabetes and hypertension. Results of a thyroid function test were as follows: T3 = 130.40 ng/dL, TSH = 0.06 mIU/L, and free T4 = 1.73 ng/dL. A thyroid scan exhibited a decreased uptake (0.6%). His symptoms clearly improved and serum potassium levels increased to 4.4 mmol/L by intravenous infusion of only 40 mmol of potassium chloride. Eight months after the discontinuation of only Salicornia herbacea, the patient's thyroid function tests were normalized. Large amounts of iodine can induce hypokalemic thyrotoxic paralysis and it may be necessary to inquire about the ingestion of iatrogenic iodine compounds, such as Salicornia herbacea.

    ABSTRACT: This article describes the anuric acute renal failure (ARF) secondary to massive pericardial effusion without tamponade in an 84 year-old man. He was referred to our emergency room with progressive dyspnea and azotemia. An electrocardiogram showed sinus tachycardia. A two-dimensional echocardiogram confirmed the presence of severe pericardial effusion without prominent ventricular diastolic collapse and there were no changes in his vital signs. Laboratory findings showed that his blood urea nitrogen and serum creatinine levels were 91.8 and 3.77 mg/dL, respectively. Renal ultrasonography showed no signs of hydronephrosis. Urine output did not increase in spite of giving a saline and furosemide infusion but increased immediately after pericardiocentesis with drainage. His renal function was completely restored 3 days after the procedure. A pericardial biopsy demonstrated invasion of malignant cells. We should keep in mind that pericardial effusion is one of the causes of anuric ARF, although it is not accompanied by tamponade.

    ABSTRACT: A 74-year-old woman was admitted to our emergency room complaining of general weakness and anorexia that started 20 days earlier. She denied other underlying diseases that might have provoked chronic renal disease. Her serum creatinine was 12.35 mg/dL. A pelvic examination and computed tomography revealed severe bilateral hydroureteronephrosis with marked cortical thinning induced by total uterine prolapse. She was started on emergency hemodialysis due to her uremic symptoms and severe metabolic acidosis. Despite Foley catheter insertion and manual reduction of uterus for 1 month, renal function was not recovered. The department of gynecology was strongly opposed to performing a procedure to reverse the hydroureteronephrosis due to the irreversibility of her renal function. She is undergoing chronic maintenance hemodialysis. This is a case report of rare end-stage renal disease (ESRD) caused by obstructive uropathy due to pelvic organ prolapse (POP). We should consider POP as a cause of ESRD.

    ABSTRACT: Mantle cell lymphoma (MCL), owing to its insensitivity to chemotherapy, has a poor prognosis, with a median survival of 3 years to 4 years. MCL frequently infiltrates other organs. However, reports involving kidney in living patients are rare. Here, we report a case of MCL with renal involvement leading to end stage renal disease that required renal replacement therapy. A 69-year-old man diagnosed with MCL 3 years earlier was admitted to our emergency room due to uremic symptoms. After eight cycles of chemotherapy, he had displayed complete remission, but experienced a recurrence 1.5 years later; after refusing chemotherapy, the patient was lost on follow-up in the final 10 months. On presentation at the emergency room, the patient's serum blood urea nitrogen was 109.5 mg/dL, and creatinine was 11.1 mg/dL. All serological markers for secondary glomerulonephritis were negative. Renal biopsy revealed 50% sclerosis of the glomerulus and small dense lymphocyte infiltration of the tubulo-interstitium. Similar cells were found on the gastric mucosa. Despite our recommendation for chemotherapy, he refused all treatments except for hemodialysis, which was maintained for 12 months until his death. This patient represents the first case report of the renal involvement of MCL leading to end stage renal disease.

    ABSTRACT: Transcatheter arterial chemoembolization (TACE) is an effective treatment for unresectable hepatocellular carcinoma (HCC); however, large volumes of radiocontrast agents are used for TACE and may induce renal dysfunction. Most patients with HCC have coexisting liver cirrhosis (LC) at the time of diagnosis. Advanced cirrhosis is characterized by peripheral vasodilatation associated with decreased renal perfusion due to the activation of vasoconstrictor systems. We retrospectively investigated patients with HCC who had undergone TACE to determine the incidence and risk factors for radiocontrast-induced nephropathy (RCIN). A total of 101 patients with HCC who underwent a combined 221 TACE treatment sessions were included. Follow-up serum creatinine levels within 96 h after TACE were confirmed in these patients. RCIN was defined as an increase of at least 25% in baseline serum creatinine levels between 48 and 96 h after TACE. RCIN developed in 20 (9%) of the 221 treatment sessions after TACE. A univariate analysis showed that the Child-Pugh score (6.0 ± 1.3 vs. 6.7 ± 1.9, P = 0.005), ascites (14.4 vs. 40%, P = 0.008), contrast medium volume (257.3 ± 66.8 vs. 275.0 ± 44.0 ml, P = 0.009), total bilirubin (1.3 ± 1.7 vs. 3.4 ± 8.0 mg/dl, P < 0.001), basal serum creatinine levels (0.9 ± 0.3 vs. 1.0 ± 0.5 mg/dl, P < 0.001) and glomerular filtration rate using the modification of diet in renal disease formula (90.5 ± 21.8 vs. 88.4 ± 29.6 ml/min, P = 0.015) were significantly associated with the development of RCIN. A multivariate analysis revealed that the Child-Pugh score was associated with RCIN [odds ratio (OR) 1.5; P = 0.015]. Overall, in-hospital mortality after TACE was 4.07% (with RCIN, 30%; without RCIN, 1.5%; P < 0.001). The multivariate analysis also showed that the Child-Pugh score and the occurrence of RCIN were associated with in-hospital mortality after TACE (OR 2.8; P = 0.001; OR 26.7, P = 0.002, respectively). RCIN after TACE was closely associated with the severity of LC. Effective preventive measures remain to be determined in patients with HCC and advanced LC who are undergoing TACE.

    ABSTRACT: Uremic optic neuropathy (UON) is extremely rare, although sporadic cases have been reported. UON is sometimes regarded as a manifestation of uremic neuropathy. Here, we report a case of end-stage renal disease presenting as UON. A 22-year-old male was transferred to our nephrology department due to azotemia. Sudden deterioration of his vision occurred 3 days before his transfer. The patient's blood pressure was 150/90 mmHg, and he had no symptoms or signs of uremia, except for the visual disturbance. Blood tests showed an elevated serum creatinine of 6.0 mg/dL and serum BUN of 53.6 mg/dL. Both kidneys were decreased in size on ultrasound. His best-corrected vision was 20/62.5 in both the eyes. Ophthalmoscopy revealed hyperemia, swelling of both optic nerve heads, and blurred margins of both optic disks. These findings are compatible with UON. The patient's visual acuity and visual field improved following hemodialysis and corticosteroid treatment. The swelling of the patient's optic disks was also resolved. The patient is currently undergoing hemodialysis with the goal of vision restoration. Uremic optic neuropathy should be considered when patients with advanced chronic kidney disease complain of deterioration of their vision.

    ABSTRACT: A 22-year-old man was diagnosed with isolated mediastinal myeloid sarcoma which radiologically mimicked primary mediastinal lymphoma. Despite administration of standard remission induction chemotherapy with daunorubicin and cytarabine, and three cycles of intensive high-dose cytarabine-based consolidation, chemo-resistant hypermetabolic lesions were persistently detected in the highest mediastinum and in the supraclavicular area. However, complete remission and long-term survival were achieved by curative radiotherapy followed by unrelated allogeneic stem cell transplantation.
