, Ki Tae Bang, Jong Ho Shin, Ju Ri Kim, Joo Heon Kim, Jin Uk Jeong A 35-year-old man presented with progressive dyspnea and hemoptysis. His blood pressure was 230/140 mmHg and serum creatinine level was 20.13 mg/dL. Chest radiography and computed tomography revealed pulmonary hemorrhage. His renal function was low, thus emergent renal replacement therapy was required. Malignant hypertension and acute kidney injury were diagnosed, and antihypertensive therapy and hemodialysis started immediately. Renal biopsy was performed to examine the underlying disease. Typical pathological changes of malignant hypertension, fibrinoid necrosis of the afferent arterioles, and proliferative endoarteritis at the interlobular arteries were observed. His renal function improved gradually and pulmonary hemorrhage completely disappeared with administration of antihypertensive agents. Here, we report this rare case of malignant hypertension with pulmonary alveolar hemorrhage and speculate that the hemorrhage may be related to vascular injuries at the alveolar capillary level caused by malignant hypertension.
, Sung Jin Kim, Ji Hei Cha, Seung Joo Lee, Sejung Sohn Influenza virus infection is a common respiratory disease in children. Renal complications of influenza infection were not commonly encountered until the 2009 H1N1 influenza pandemic, when acute kidney injury (AKI) frequently developed in severely ill patients. Kawasaki disease (KD) is another rare association in pandemic influenza virus infections. There are some reports about KD coincident with influenza A H1N1/09 infection. However, simultaneous AKI and KD in influenza A or B virus infections have never been reported. Herein, we report the first case of influenza B virus infection that initially presented as AKI but was subsequently diagnosed as atypical KD.
, Youn Kyung Kee, Eunyoung Lee, Choong-kun Lee, Seung Gyu Han, Su Jin Heo, Tae-Hyun Yoo Malakoplakia is an uncommon chronic granulomatous inflammatory disease which is associated with immunocompromised conditions such as malignancy, autoimmune disease, chronic alcohol intake, poorly controlled diabetes and long-term steroid use. Malakoplakia can occur at various sites, most commonly in the genitourinary tract including urinary bladder and the ureter. Renal parenchymal involvement is relatively uncommon, accounting for 15% of all malakoplakia. A few cases of renal malakoplakia have been reported in Korea, and only one case was accompanied by acute kidney injury. Here we report an 80-year-old female patient with renal parenchymal malakoplakia and acute interstitial nephritis presented as acute kidney injury with literature review.
