ABSTRACT
Background/Aims@#To investigate if BK virus (BKV)-specific T cell immunity measured by an interferon-γ enzyme-linked immunospot (ELISPOT) assay can predict the outcome of BK virus infection in kidney transplant recipients (KTRs). @*Methods@#We included 68 KTRs with different viremia status (no viremia [n = 17], BK viremia [n = 27], and cleared viremia [n = 24]) and 44 healthy controls (HCs). The BK viremia group was divided into controller ( 3 months) according to sustained duration of BKV infection. We compared BKV-ELISPOT results against five BKV peptides (large tumor antigen [LT], St, VP1-3). @*Results@#BKV-ELISPOT results were higher in three KTRs groups with different BKV infection status than the HCs group (p < 0.05). In KTR groups, they were higher in cleared viremia group than no viremia or BK viremia group. Within the BK viremia group, controller group had higher LT-ELISPOT results compared to noncontroller group (p = 0.032). Also, KTRs without BK virus-associated nephropathy (BKVN) had higher LT, St, VP1, and VP2-ELISPOT results than those with BKVN (p < 0.05). @*Conclusions@#BKV-ELISPOT assay may be effective in predicting clinical outcomes of BKV infection in terms of clearance of BK virus and development of BKVN.
ABSTRACT
Lymphoproliferative disorder in a posttransplant setting has emerged as a difficult problem in kidney transplantation (KT). Lymphoma involving adnexa of the eye has rarely been reported due to scarcity of lymphoreticular tissue in the ocular area. This report presents a case of a 37-year-old KT recipient who was diagnosed with conjunctival mucosa-associated lymphoid tissue lymphoma with a chief complaint of seeing black spots. Unlike other post-transplant lymphoproliferative diseases associated with the Epstein-Barr virus (EBV) reactivation via immunosuppression, the lesion was not related to the virus. The patient received radiotherapy with concomitant conversion from the tacrolimus to the sirolimus. Overall, the results presented herein indicate lymphoma may be an important differential diagnosis when KT recipients complain of ocular discomfort.

BACKGROUND: Successful pregnancy outcomes in patients with advanced chronic kidney disease (CKD) are increasingly common in Western countries. However, in Korea, the available literature addressing this clinical issue is scarce. METHODS: We reviewed 5 successful parturitions [1 patient with Stage 5 CKD and 4 with maintenance hemodialysis (HD)] at Seoul St. Mary's Hospital over 3 years and investigated changes in dialysis prescription, anemia management, and the incidence of maternal and neonatal complications. RESULTS: There were no maternal or neonatal deaths in this cohort. The mean age at the time of conception and delivery was 35.8 ± 3.7 and 36.2 ± 3.5 years, respectively. Dialysis patients received more frequent and intensified HD during pregnancy, 20.0 ± 5.7 h/wk of HD over 5 visits with the ultrafiltration dose maintained between 1 and 2 kg per session. All patients received erythropoietin-stimulating agents and iron replacement therapy during pregnancy. The mean hematocrit was 33.1 ± 1.9% before pregnancy and was well maintained during gestation (33.9 ± 3.8% at the first trimester, 29.2 ± 4.2% at the second trimester, and 33.6 ± 8.7% at delivery). The mean gestation period was 32.7 ± 4.7 weeks, with 60% of patients experiencing premature delivery. The primary maternal complication was pre-eclampsia; 3 women developed pre-eclampsia and underwent emergency cesarean sections. Most neonatal complications were related to preterm birth. CONCLUSION: Dialysis-related care and general clinical management improved the clinical outcome of pregnancy for patients with advanced CKD.

BACKGROUND: Longer needle and complicated insulin injection technique such as injecting at a 45-degree angle and making skinfolds may decrease patient compliance to insulin injection therapy. In this light, shorter insulin needles have been recently developed. However, it is necessary to ascertain that such shorter needles are appropriate for Korean patients with diabetes as well. METHODS: First, the diverse demographic and diabetic features of 156 Korean adults with diabetes were collected by a questionnaire and a device unit of body fat measurement. The skin and subcutaneous fat thicknesses of each subject were measured by Ultrasound device with a 7- to 12-MHz probe. Data were analyzed using analysis of variance and multiple linear regression. RESULTS: The mean skin thickness was 2.29+/-0.37 mm in the abdomen and 2.00+/-0.34 mm in the upper arms, and the mean subcutaneous fat thickness was to 10.15+/-6.54 mm in the abdomen and 5.50+/-2.68 mm in the upper arms. Our analysis showed that the factors affecting the skin thickness of the abdomen and upper arms were gender and body mass index (BMI), whereas the factors influencing the subcutaneous fat thickness in the abdomen were gender and BMI, and the factors influencing the subcutaneous fat thickness in the upper arms were gender, BMI, and age. Insulin fluids may not appear to be intradermally injected into the abdomen and upper arms at any needle lengths. The risk of intramuscular injection is likely to increase with longer insulin needles and lower BMI. CONCLUSION: It is recommended to fully inform the patients about the lengths of needles for insulin injections. As for the recommended needle length, the findings of this study indicate that needles as short as 4 mm are sufficient to deliver insulin for Korean patients with diabetes.
