PURPOSE: The goal of this study was to investigate the association between hypercholesterolemia and the time required for progression to castration-resistant prostate cancer (CRPC) in patients who have undergone androgen deprivation therapy (ADT). MATERIALS AND METHODS: Data from 154 patients with prostate cancer between 2005 and 2012 were reviewed retrospectively. ADT was employed as a treatment modality for these patients either due to multiple bone metastases at the time of diagnosis or due to old age in combination with other morbidities. Serum cholesterol levels and statin use were reviewed. We analyzed the factors associated with the development of CRPC after ADT treatment. The mean follow-up period was 34.8 months. RESULTS: The mean age of the patients was 71.3 years old and their mean prostate-specific antigen level was 141.8±212.6 ng/mL. Their mean cholesterol level was 175.9±37.7 mg/dL, and 14 patients (9.1%) were statin users. CRPC developed in 44 patients (28.6%), and the mean duration from ADT treatment to CRPC was 24.1 months. In a multivariate analysis, hypercholesterolemia was associated with the development of CRPC (hazard ratio [HR]=1.017, p<0.001), depending on clinical T stage (p=0.005) and the presence of bone metastasis (p<0.001). A subanalysis showed that hypercholesterolemia was associated with the development of CRPC in patients with bone metastasis (HR=1.032, p<0.001), but not in patients without bone metastasis. CONCLUSIONS: Hypercholesterolemia may be associated with the development of CRPC after ADT in patients with bone metastasis. Further studies with longer follow-up periods and larger samples are needed to validate this finding.

Hemangioma of the liver is usually asymptomatic and incidentally discovered. However, giant hemangioma of the liver may be symptomatic, which is an indication for treatment. A 31-year-old female was admitted with a fever and 1-month history of a nonproductive cough. Her blood test results revealed thrombocytopenia, anemia, and mild coagulopathy. A giant hemangioma of the liver was the cause of her symptoms and signs, and was too large for surgical treatment. Therefore, we performed two sessions of transcatheter hepatic arterial embolization (TAE). The patient has been doing well without fever for 1 year following the second TAE procedure. Surgical resection and enucleation are the traditional treatments of choice for symptomatic giant hemangioma of the liver. However, the signs and symptoms of giant hemangioma of the liver improved by TAE in the present case. We herein report a case of complicated giant hemangioma of the liver that was partially treated by TAE and conservative management.

On the 12th day of abacavir treatment, a 39-year old HIV-infected male patient was admitted with fever, generalized rash, abdominal pain, and watery diarrhea that had persisted for five days. Results of blood tests indicated rapid progression of hepatitis and renal failure. The day after stopping anti-retroviral therapy, his fever subsided and his liver function began to normalize. He was clinically diagnosed with abacavir hypersensitivity and was found to carry the HLA-B*57:01 allele. This is the first reported case of abacavir hypersensitivity associated with the presence of the HLA-B*57:01 allele in Korea.

BACKGROUND/AIMS: The disease course and factors associated with poor prognosis in Korean patients with Crohn’s disease (CD) have not been fully determined. The aim of this study was to explore potential associations between the clinical characteristics and long-term outcomes of CD and perianal fistulas in a Korean population. METHODS: The retrospective Crohn’s Disease Clinical Network and Cohort (CONNECT) study enrolled patients diagnosed with CD between July 1982 and December 2008 from 32 hospitals. Those followed for < 12 months were excluded. Clinical outcomes were CD-related surgery and complications, including nonperianal fistulas, strictures, and intra-abdominal abscesses. RESULTS: The mean follow-up period was 8.77 years (range, 1.0 to 25.8 years). A total of 1,193 CD patients were enrolled, of whom 465 (39.0%) experienced perianal fistulas. Perianal fistulizing CD was significantly associated with younger age, male gender, CD diagnosed at primary care clinics, and ileocolonic involvement. Both nonperianal fistulas (p=0.034) and intra-abdominal abscesses (p=0.020) were significantly more common in CD patients with perianal fistulas than in those without perianal fistulas. The rates of complicated strictures and CD-related surgery were similar between the groups. Independently associated factors of nonperianal fistulas were perianal fistulas (p=0.015), female gender (p=0.048), CD diagnosed at referral hospital (p=0.003), and upper gastrointestinal (UGI) involvement (p=0.001). Furthermore, perianal fistulas (p=0.048) and UGI involvement (p=0.012) were independently associated with the risk of intra-abdominal abscesses. CONCLUSIONS: Perianal fistulas predicted the development of nonperianal fistulas and intra-abdominal abscesses in Korean CD patients. Therefore, patients with perianal fistulizing CD should be carefully monitored for complicated fistulas or abscesses.
