Light chain deposition disease (LCDD) is characterized by the deposition of abnormal immunoglobulin light chains in many organs, including kidney. It is usually associated with multiple myeloma or other lymphoproliferative disorders. Myeloma usually occurs in old age and may develop after renal transplantation thus being categorized as posttransplant lymphoproliferative disease (PTLD). Renal LCDD usually presents with variable degree of proteinuria and renal insufficiency. The diagnosis of LCDD depends on histologic findings with detection of monoclonal immunoglobulin light chain. Histologically, it is characterized by nodular glomerulosclerosis. We report the first case of de novo LCDD associated with myeloma after renal transplantation in Korea. With advancing renal transplantation and increasing old aged renal recipients, myeloma or LCDD should be included in the differential diagnoses of renal recipient patients with deteriorating renal function.

A spontaneous subcapsular hematoma in an allograft kidney is a rare condition with only a few cases reported in the literature. Common causes of subcapsular hematoma of an allograft include trauma, post-biopsy status, occult malignancy, vascular diseases, and infection. Chronic allograft dysfunction related to spontaneous subcapsular hematoma is extremely rare. We report a case of spontaneous subcapsular hematoma in a patient who underwent a renal transplant 14 years ago in which we could not find an associated condition.

PURPOSE: This study was planned to determine the efficacy and safety of mycophenolate mofetil (MMF) as a rescue treatment in patients with membranous nephropathy (MN) and focal segmental glomerulosclerosis (FSGS) who were not responsive to standard therapy with steroid and immunosuppressive regimen. METHODS: We planned a prospective, non-randomized study from Oct. 2002 to Aug. 2009, including biopsy-proven MN or FSGS patients in Keimyung university Dongsan hospital. MMF was initiated at 0.5-0.75 g twice daily, and advanced as appropriate or as tolerated to 0.75-1 g twice daily. RESULTS: 14 cases with MN and 5 cases with FSGS was enrolled. The mean age of patients was 51.7+/-12.3 years, and mean treatment duration was 14.4+/-6.5 months. Five patients (26.4%) went into complete remission and the seven (36.8%) into partial remission. The mean value of 24hr total urine protein over the follow-up 6 months' period declined significantly from 7.6+/-6.2 g in pre-treatment, to 4.1+/-3.2 g in 3 months, and 3.1+/-2.1 g in 6 months (p=0.011). The mean 24hr total urine protein decreased from 7.5+/-6.3 g in pre-MMF to 1.9+/-1.8 g in post-MMF (p=0.001). The mean serum albumin rose from 3.2+/-0.8 g/dL in pre-MMF to 3.9+/-0.5 g/dL in post-MMF (p=0.001). There were no significant changes in mean value for WBC, hemoglobin, serum creatinine, and total cholesterol. Side effects of MMF were infrequent and generally mild. CONCLUSION: MMF appears effective in 63% of patients with MN and FSGS who are resistant to other forms of treatment. Studies with more cases and multicenter controlled trials are required to establish the role and standards of MMF in these disorders.

BACKGROUND: The incidence of acute rejection has decreased with the introduction of new immunosuppressive agents. However, several studies have shown that allograft survival has not clearly improved over the past few decades. METHODS: We reviewed patients who underwent kidney transplantation between 1982 and 2007. We compared the causes of graft loss for three decades: 1982~1990 (period I),1991~2000 (period II), and 2001~2007 (period III), with the clinical characteristics of patients with functioning grafts and patients who lost their allografts. RESULTS: There were 785 recipients with a mean age of 36.1 years, and 65.2% were male. Graft loss occurred in 329 patients (41.9%), and the most common cause of graft loss was chronic allograft nephropathy (CAN, 52.0%), followed by patient death (17.6%), post-transplant glomerulonephritis (12.8%), and non compliance (7.9%). During the three time periods, 129, 172, and 28 patients lost their grafts, respectively. Five-year graft survival was 61.5%, 78.4%, and 90.8%, respectively, and increased significantly (P<0.000). CAN, as a cause of graft loss, fell from 65.1% (period I) to 32.1% (period III, P<0.000), but patient death increased from 12.4% to 32.1% (P=0.034). A multivariate analysis revealed that significant risk factors for graft loss included an older donor, transplantation at period I, and dual immunosuppression. Use of tacrolimus and mycophenolate mofetil was associated with a significantly reduced risk of graft loss. CONCLUSIONS: Graft survival has increased over the last three decades whereas the proportion of CAN, the most common cause of graft loss, has decreased. Attention to the main causes of graft loss, CAN, and patient death will offer potential improvement in graft survival.

PURPOSE: Peritoneal dialysis (PD) catheter removal is regarded as an important index of patient morbidity. The aim of this study was to evaluate factors influencing catheter loss following peritonitis in PD patients. METHODS: We retrospectively reviewed 917 episodes of peritonitis in 621 new CAPD patients from Jan 2001 to Feb. 2009 in Dongsan Medical center. Episodes requiring PD catheter removal were compared by both univariate and multivariate analyses with those in which PD catheters were preserved. RESULTS: When peritonitis episodes requiring PD catheter removal (n=80) were compared to catheter preserved peritonitis episodes (n=837), the incidence of PD catheter loss increased as the duration on PD preceding the peritonitis were longer (p<0.000). Also, PD catheter removal was more likely to occur after peritonitis episodes with low serum albumin level (p=0.009) and high serum CRP level (p<0.000), those with long duration of PD effluent leukocyte count remaining above 100/mm3 (p<0.000), those with concomitant exit site/tunnel infection (p=0.043), and those with presence of abdominal pathology (p<0.000). The microbiological determinants of PD catheter loss included two or more bacteria cultured (p=0.002) and fungi (p<0.000). In multivariate analysis, the duration of PD effluent leukocyte count remaining above 100/mL and the number of organism cultured were independent risk factors of PD catheter removal in peritonitis episodes. CONCLUSION: Duration of PD effluent leukocyte count remaining above 100/mm3, and the number of organisms cultured were independent risk factors for catheter removal following peritonitis.

OBJECTIVES: This study developed an information and communication technology (ICT)-based comprehensive health and social-needs assessment (CHSNA) system based on the International Classification of Functioning, Disability, and Health (ICF) with the aim of enhancing person-centered community care for community residents and supporting healthcare professionals and social workers who provide healthcare and social services in the community. METHODS: Items related to a CHSNA tool were developed and mapped with ICF codes. Experts validated the CHSNA system design and process using the Delphi method, and a pilot test of the initial version of the system was conducted. RESULTS: The following three steps of CHSNA were embedded in the system, which had a user-friendly screen and images: basic health assessment, life and activity assessment, and in-depth health assessment. The assessment results for the community residents were presented with visualized health profiles, including images, graphs, and an ICF model. CONCLUSIONS: The developed CHSNA system can be used by healthcare professionals, social workers, and community residents to evaluate the reasoning underlying health and social needs, to facilitate the identification of more appropriate healthcare plans, and to guide community residents to receive the best healthcare services. A CHSNA system can improve the implementation of standardized terminology utilizing the ICF and the accuracy of needs assessments of community residents.

Background: This study aimed to investigate the recent prevalence, management, and comorbidities of diabetes among Korean adults aged ≥30 years by analyzing nationally representative data. Methods: This study used data from the Korea National Health and Nutrition Examination Survey from 2016 to 2018, and the percentage and total number of people ≥30 years of age with diabetes and impaired fasting glucose (IFG) were estimated. Results: In 2018, 13.8% of Korean adults aged ≥30 years had diabetes, and adults aged ≥65 years showed a prevalence rate of 28%. The prevalence of IFG was 26.9% in adults aged ≥30 years. From 2016 to 2018, 35% of the subjects with diabetes were not aware of their condition. Regarding comorbidities, 53.2% and 61.3% were obese and hypertensive, respectively, and 72% had hypercholesterolemia as defined by low-density lipoprotein cholesterol (LDL-C) ≥100 mg/dL in people with diabetes. Of the subjects with diabetes, 43.7% had both hypertension and hypercholesterolemia. With regard to glycemic control, only 28.3% reached the target level of <6.5%. Moreover, only 11.5% of subjects with diabetes met all three targets of glycosylated hemoglobin, blood pressure, and LDL-C. The percentage of energy intake from carbohydrates was higher in diabetes patients than in those without diabetes, while that from protein and fat was lower in subjects with diabetes. Conclusion The high prevalence and low control rate of diabetes and its comorbidities in Korean adults were confirmed. More stringent efforts are needed to improve the comprehensive management of diabetes to reduce diabetes-related morbidity and mortality.
