The authors report the case of a 25 year old woman with a chronic corticosteroid-refractory nephrotic syndrome complicated by myocardial infarction. The thromboembolism, especially acute myocardial infarction, is the most serious complication of nephrotic syndrome. Until now many mechanisms have been studied about thromboem bolism including coronary artery disease in nephrotic syndrome, but not clear. Hypercoagulability and prolonged hyperlipidemia are known as the principal contributing factors in this complication. In addition, use of steroid as therapeutic trial and hypovolemic state induced by vigorous diuretics will affect the thromboembolism, too. In this case, several coagulation abnormality and prolonged hyperlipidemia are observed. On admission day, this patient had deep vein thrombosis and then was complicated by pulmonary thromboembolism. Despite of anticoagulant and thrombolytic therapy, she experienced acute myocardial infarction on fourth day after admission. After onset of myocardial infarction, by thrombolytics and prolonged anticoagulant therapy, this nephrotic patient was relieved and discharged without other serious complication. We recommend anticoagulant and antiplatelet agent therpy in risky patient of nephrotic syndrome. We present this case with review of literature.

Nephrogenic fibrosing dermopathy (NFD) is a rare cutaneous fibrosing disorder that primarily affects patients with a history of renal disease. NFD manifests with induration, thickening and hardening of the skin with brawny hyperpigmentation. Lesions are typically symmetrical and usually develop on the limbs and trunk. Flexion contractures of the joints may be a feature of the disease. Histopathological features of NFD include proliferation of dermal fibroblasts and dendritic cells, thickened collagen bundles, increased elastic fibers and focal mucin deposition. Although the pathogenesis remains largely unknown, some of the factors implicated in the pathogenesis include renal dysfunction, circulating fibrocytes, vascular injury, and gadolinium which is a contrast material used in magnetic resonance imaging. Currently, no definitive or uniformly effective therapies are available for the treatment of NFD. We herein describe the case of a 44-year-old female NFD patient who undergoes significant improvement of skin lesions and associated joint contracture after renal transplantation.

Mycobacterium marinum is a nontuberculous mycobacterium responsible for skin infection. Risk factors include a history of trauma and water/fish-related hobbies or occupations. This infection is characteristically limited to the skin but deep soft tissue may be involved. We report a case of M. marinum infection in a 51-year-old man with ulcer and erythematous nodules on his right hand. The patient owned a tropical fish tank and remembered having previous hand trauma. The lesions extended to his forearm and formed sporotrichoid appearance. M. marinum was isolated from tissue specimens. The patient was treated with rifampin, etambutol and clarithromycin for 5 months, then the skin lesions were cured. The key to the diagnosis of this case are clinical awareness and a detailed history. M. marinum infection should be considered in chronic sporotrichoid skin lesions, particularly when there is a clinical suspicion on an infectious cause, and it could lead to successful treatment.

We report 2 cases of chronic estimated glomerular filtration rate (eGFR) decline after unilateral adrenalectomy due to primary aldosteronism. The patients were diagnosed with unilateral adrenal cortical adenoma releasing aldosterone. Two patients were examined for hypertension and hypokalemia. Unilateral laparoscopic adrenalectomy was performed in both cases, and pathology confirmed adrenal cortical adenoma. After adrenalectomy, hypertension and hypokalemia improved to within normal range. However, the eGFR decreased postoperatively, and abdominal computed tomography scan showed decreased kidney size compared to previous images. Kidney biopsy was performed to delineate the exact cause of renal function deterioration and revealed hypertensive changes with chronic interstitial changes, indicating that glomerular hyperfiltration with aldosterone excess masked renal function damage. Physicians have to consider the probability of postadrenalectomy eGFR decline related to chronic hypertensive change.

Poor retention in care (RIC) is associated with higher antiretroviral therapy (ART) failure and worse survival. Identifying high risk patients for poor RIC is important for targeted intervention. A retrospective cohort study was conducted at a tertiary care hospital in Korea. HIV-infected patients initiating ART during 2002-2008 were included. 5 year-RIC was measured by hospital visit constancy (HVC) at 5 years after initiating ART. Among 247 enrolled patients, 179 (72.5%) remained in care, 20 (8.1%) were transferred to other hospitals, 9 (3.6%) died and 39 (15.8%) were lost to follow-up. We compared the demographic, psychosocial, and clinical characteristics between the groups with 100% HVC (n = 166, 67.2%) and < or = 50% HVC (n = 33, 13.4%). In multivariable analysis, ART-starting age < or = 30 years (odds ratio [OR] 4.08 vs. > 50; 95% confidence interval [CI] 1.10-15.15, P = 0.036), no non-HIV related comorbidity (OR 2.94 vs. comorbidity > or = 1; 95% CI 1.02-8.49, P = 0.046), baseline CD4 cell count > 300 cells/muL (OR 3.58 vs. < or = 200; 95% CI 1.33-9.65, P = 0.012) were significant predictable factors of poor RIC. HIV/AIDS care-givers should pay attention to young patients with higher baseline CD4 cell counts and no non-HIV related comorbidity.

BACKGROUND: Oral sodium phosphate (NaP) is currently used for colon preparation prior to colonoscopy or barium enema because of its convenience and efficacy. It can cause transient hyperphosphatemia and should be considered potentially dangerous in the presence of renal impairment. METHODS: A retrospective study was done in 48 patients (32 patients with normal renal function and 16 patients with azotemia : serum creatinine >or= 1.4 mg/dL) with hyperphosphatemia (serum phosphate >or= 6 mg/dL or 50% increase in baseline) who were administered NaP solution as bowel preparation at Seoul National University Hospital in the period of January 2000 to June 2003. RESULTS: The patients' mean age was 60 years (range, 25-85 years). The increase of serum phosphate was 5.3 +/- 3.1 mg/dL (7.6 +/- 4.4 mg/dL in azotemia group vs. 4.2 +/- 1.2 mg/dL in normal renal function group). Serum calcium and potassium concentration decreased significantly, while serum sodium level increased significantly. There were no significant differences in serum chloride, total CO2, blood urea nitrogen and creatinine. The product of calcium and phosphate increased from 33.0 +/- 11.3 mg2/dL2 to 74.0 +/- 28.7 mg2/dL2 (to 93.0 +/- 39.8 mg2/dL2 in azotemia group). Only 8 patients ingested the recommended dose of oral NaP with an appropriate time interval. The symptomatic adverse events were numbness in 3 patients and carpopedal spasm in 1 patient. 12 patients underwent CaCO3 or amphojel administration and 1 patient needed hemodialysis as a treatment of hyperphosphatemia. Serum phosphate returned to baseline level at 1.3 +/- 0.6 day (1.8 +/- 0.8 day in azotemia group vs. 1.0 +/- 0.3 day in normal renal function group). CONCLUSION: NaP is inappropriate for patients who may be at an increased risk for phosphate intoxication, especially patients with impaired renal function. Even to healthy adult without renal disease, NaP should be ingested the recommended dose with an appropriate time interval.

BACKGROUND/AIMS: Increasing incidences of hepatitis C virus (HCV) infection in human immunodeficiency virus (HIV)-infected men who have sex were reported in the United States and Europe. However, few studies regarding the epidemiology of HCV infection in HIV-infected patients in Asian countries have been reported. METHODS: To determine the prevalence and incidence of HCV infection in HIV-infected patients, a retrospective cohort study was conducted. All HIV-infected patients who visited a tertiary care hospital in Korea from 2000 to 2013 were identified. Patients with ≥ 1 HCV antibody (Ab) test were included and observed until December 2014. RESULTS: Among 996 HIV-infected patients, 790 patients (79%) had baseline HCV Ab tests and 41 (5.2%) were positive at baseline and four at follow-up. Experience of injecting drug use (IDU; adjusted odds ratio, 16.20; 95% confidence interval [CI], 1.56 to 167.89; p < 0.01) was significantly associated with prevalent HCV infection. Conversion to HCV Ab positivity was observed in four of 384 included patients, with an incidence rate of 2.22 (95% CI, 0.60 to 5.80)/1,000 person-years (PYs); 164.89 (95% CI, 34.00 to 481.88)/1,000 PYs in patients with IDU, and 1.40 (95% CI, 0.35 to 7.79)/1,000 PYs in men who have sex with men who denied IDU. There was no significant increase in incidence rate of HCV in HIV-infected patients from 2009 to 2014 (p = 0.119). Among 19 patients who were positive for HCV RNA, genotype 1b (73%) was the most common following 2a/2c (20%). CONCLUSIONS: IDU was an independent risk factor for prevalent HCV infection. Prevalence of HCV infection was low and incidence of HCV infection was not significantly increased in HIV-infected patients in South Korea.
