PURPOSE: The aim of the study is to evaluate the health-related quality of life, psychological symptoms, distress, and sense of coherence in adult haematopoietic stem cell transplantation survivors. METHODS: Fifty two survivors completed four questionnaires after the transplantation. The questionnaires were the Functional Assessment of Cancer Therapy-BMT Scale, the National Cancer Center Psychological Symptom Inventory, the Distress Thermometer, and the Sense of Coherence scale. RESULTS: Quality of life was positively correlated with sense of coherence, whereas sense of coherence was negatively correlated with all psychological symptoms and distress. Hierarchical regression analyses revealed that sense of coherence was the only significant predictor of quality of life after controlling for sex and age at transplantation. Model 2 explained 33.2% of the total variance of quality of life. CONCLUSION: Supporting patients towards improving comprehensibility, manageability and meaningfulness, the three components of sense of coherence, may be beneficial and improve outcomes. Individually pre-transplant and post-transplant assessments of sense of coherence may be of clinical importance, in order to identify patients with unmet needs and to provide rolonged support.

Thrombotic microangiopathy (TMA) is a rare complication of gemcitabine treatment. A 55-year-old man with a history of urothelial cancer underwent right ureteronephrectomy and palliative chemotherapy. The patient presented with dyspnea, generalized edema with foamy urine, and new-onset hypertension with acute kidney injury (AKI). Although AKI with oliguria was evident, thrombocytopenia and hemolytic anemia were not overt. To determine the cause of rapidly progressive azotemia, kidney biopsy was performed despite a single kidney and revealed chronic TMA. Microangiopathic hemolytic anemia and thrombocytopenia developed after renal biopsy. Diagnosed as gemcitabine-induced TMA, gemcitabine cessation and active treatment including steroids, plasmapheresis, and rituximab were carried out, but the patients condition progressed to a dialysis-dependent state. Gemcitabine-induced TMA is often difficult to diagnose because of its variable clinical course. Therefore, heightened awareness of this potentially lethal complication of gemcitabine is essential; renal biopsy may be helpful.

West Nile encephalitis was first identified in 1937, but until now, it was never diagnosed in Korea. A 58-yr-old Korean man was admitted with headache and cognitive dysfunction. The patient had been on a business trip in Guinea. Cerebrospinal fluid (CSF) showed pleocytosis. The patient complained of both leg weakness,and arachnoiditis and myelitis were observed on lumbar magnetic resonance imaging (MRI). A specific neutralizing antibody for West Nile virus was positive in serum. After a treatment with interferon-alpha 3mu, follow up CSF findings recovered completely after 3 months later. The first case of West Nile encephalitis in Korea was imported from Guinea, and was cured successfully.

Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary kidney disease. It is characterized by cyst growth in the kidneys, resulting in kidney enlargement and end-stage kidney disease. The polycystic kidney disease 1 (PKD1) and PKD2 have been identified as genes related to ADPKD and their significance in the molecular pathology of the disease has been studied. A disease-modifying drug has been approved; therefore, it has become important to identify patients at a high risk of kidney disease progression. Genetic tests, image analysis methods, and clinical factors for kidney disease progression prediction have been established. This review describes genetic and clinical characteristics, and discusses ongoing studies in Korean ADPKD patients.

IL-22, a pleiotropic cytokine, is known to have a profound effect on the regeneration of damaged intestinal barriers. The tissue-protective properties of IL-22 are expected to be potentially exploited in the attenuation and treatment of colitis. However, because of the disease-promoting role of IL-22 in chronic inflammation, a comprehensive evaluation is required to translate IL-22 into the clinical domain. Here, we present the effective production of soluble human IL-22 in bacteria to prove whether recombinant IL-22 has the ability to ameliorate colitis and inflammation. IL-22 was expressed in the form of a biologically active monomer and non-functional oligomers. Monomeric IL-22 (mIL-22) was highly purified through a series of 3 separate chromatographic methods and an enzymatic reaction. We reveal that the resulting mIL-22 is correctly folded and is able to phosphorylate STAT3 in HT-29 cells. Subsequently, we demonstrate that mIL-22 enables the attenuation of dextran sodium sulfate-induced acute colitis in mice, as well as the suppression of pro-inflammatory cytokine production. Collectively, our results suggest that the recombinant mIL-22 is suitable to study the biological roles of endogenous IL-22 in immune responses and can be developed as a biological agent associated with inflammatory disorders.

Reninoma is a tumor of the renal juxtaglomerular cell apparatus that causes hypertension and hypokalemia because of hypersecretion of renin. We present a case of a 29-year-old female patient with reninoma and concomitant variant angina. The patient had uncontrolled hypertension and elevated plasma renin activity and aldosterone levels. Imaging studies revealed a mass in the left kidney, which was further confirmed as a renin-producing lesion via selective venous catheterization. During the evaluation, the patient had acute-onset chest pain that was diagnosed as variant angina after a provocation test. After partial nephrectomy, the plasma renin activity and plasma aldosterone levels decreased and blood pressure normalized. We report a case of reninoma with variant angina.

Secondary rapidly progressive glomerulonephritis (RPGN) can be caused by many diseases and conditions, including vasculitis, systemic rheumatic diseases, infections, drugs and malignancies. Among the secondary RPGNs, malignancy-associated RPGN is extremely rare and causes renal function deterioration within several weeks to months. Thus, timely immunosuppressant therapy can improve renal outcome. Herein, we describe a case of RPGN detected simultaneously with marginal zone B-cell lymphoma. An 82-year-old male patient, who presented generalized edema and oliguria, was diagnosed with crescentic glomerulonephritis and marginal B-cell lymphoma. After the patient was given methylprednisolone pulse therapy, renal function was restored and hemodialysis was successfully discontinued without complications.
