The power of the Risk of Ovarian Malignancy Algorithm considering menopausal status: a comparison with CA 125 and HE4 / 부인종양

OBJECTIVE: To identify the power of tumor markers for predicting ovarian cancer according to menopausal status. METHODS: The medical records of 876 women with ovarian cysts were retrospectively reviewed. Cancer antigen 125 (CA 125), human epididymis protein 4 (HE4), and Risk of Ovarian Malignancy Algorithm (ROMA) were analyzed. Sensitivity, specificity, and the receiver operating characteristic (ROC) curve analyses of these tumor markers were evaluated. RESULTS: The sensitivity of ROMA was 66.7% and the specificity was 86.8% to detect ovarian malignancy. The patients were divided into 2 groups according to menopausal status: premenopause (n=532, 60.7%) and postmenopause (n=344, 39.3%). For diagnostic accuracy, ROMA was lower than HE4 in premenopausal women (82.7% vs. 91.4%) and lower than CA 125 in postmenopausal women (86.9% vs. 88.7%). The ROC curve analysis revealed that the power of ROMA was not significantly better than that of HE4 in premenopausal women (area under the curve [AUC], 0.731 vs. 0.732, p=0.832), and it was also not significantly better than that of CA 125 in postmenopausal women (AUC, 0.871 vs. 0.888, p=0.440). CONCLUSION: The discrimination power of tumor markers for ovarian cancer was different according to menopausal status. In predicting ovarian malignancy, ROMA was neither superior to HE4 in premenopausal women nor superior to CA 125 in postmenopausal women.

Comparison of the clinical outcome of frozen-thawed embryo transfer with and without pretreatment with a gonadotropin-releasing hormone agonist

OBJECTIVE: To describe the clinical outcomes of frozen-thawed embryo transfer (FET) with artificial preparation of the endometrium, using a combination of estrogen (E2) and progesterone (P4) with or without a gonadotropin-releasing hormone agonist (GnRHa), and the modified natural cycle (MNC) with human chorionic gonadotropin (hCG) trigger. METHODS: In this retrospective study, we evaluated 187 patients during 3 years (February 2012–April 2015). The patients were allocated to the following treatment groups: group A, comprising 113 patients (181 cycles) who received GnRHa+E2+P4; group B, comprising 49 patients (88 cycles) who received E2+P4; and group C, comprising 25 patients (42 cycles) who received hCG+P4. The inclusion criteria were regular menstrual cycles (length 24–35 days) and age 21–45 years. RESULTS: The primary outcome of the study — implantation rate (IR) per embryo transferred — was not statistically different among the 3 groups. Similar results were found for the IRs with fetal heartbeat per embryo transferred (68/181 [37.6%] in group A vs. 22/88 [25.0%] in group B vs. 14/42 [33.3%] in group C) and for the live birth rates (LBRs) per embryo transferred (56/181 [30.9%] in group A vs. 18/88 [20.5%] in group B vs. 11/42 [26.2%] in group C). CONCLUSION: Although the pregnancy outcomes were better in the hormone therapy with GnRHa group, hormone therapy FET with GnRHa for pituitary suppression did not result in significantly improved IRs and LBRs when compared with hormone therapy FET without GnRHa or MNC FET.

Analysis of the Vaginal Microbiome by Next-Generation Sequencing and Evaluation of its Performance as a Clinical Diagnostic Tool in Vaginitis

BACKGROUND: Next-generation sequencing (NGS) can detect many more microorganisms of a microbiome than traditional methods. This study aimed to analyze the vaginal microbiomes of Korean women by using NGS that included bacteria and other microorganisms. The NGS results were compared with the results of other assays, and NGS was evaluated for its feasibility for predicting vaginitis. METHODS: In total, 89 vaginal swab specimens were collected. Microscopic examinations of Gram staining and microbiological cultures were conducted on 67 specimens. NGS was performed with GS junior system on all of the vaginal specimens for the 16S rRNA, internal transcribed spacer (ITS), and Tvk genes to detect bacteria, fungi, and Trichomonas vaginalis. In addition, DNA probe assays of the Candida spp., Gardnerella vaginalis, and Trichomonas vaginalis were performed. Various predictors of diversity that were obtained from the NGS data were analyzed to predict vaginitis. RESULTS: ITS sequences were obtained in most of the specimens (56.2%). The compositions of the intermediate and vaginitis Nugent score groups were similar to each other but differed from the composition of the normal score group. The fraction of the Lactobacillus spp. showed the highest area under the curve value (0.8559) in ROC curve analysis. The NGS and DNA probe assay results showed good agreement (range, 86.2-89.7%). CONCLUSIONS: Fungi as well as bacteria should be considered for the investigation of vaginal microbiome. The intermediate and vaginitis Nugent score groups were indistinguishable in NGS. NGS is a promising diagnostic tool of the vaginal microbiome and vaginitis, although some problems need to be resolved.

Systemic Classification for a New Diagnostic Approach to Acute Abdominal Pain in Children / 대한소아소화기영양학회지

PURPOSE: With previous methods based on only age and location, there are many difficulties in identifying the etiology of acute abdominal pain in children. We sought to develop a new systematic classification of acute abdominal pain and to give some helps to physicians encountering difficulties in diagnoses. METHODS: From March 2005 to May 2010, clinical data were collected retrospectively from 442 children hospitalized due to acute abdominal pain with no apparent underlying disease. According to the final diagnoses, diseases that caused acute abdominal pain were classified into nine groups. RESULTS: The nine groups were group I "catastrophic surgical abdomen" (7 patients, 1.6%), group II "acute appendicitis and mesenteric lymphadenitis" (56 patients, 12.7%), group III "intestinal obstruction" (57 patients, 12.9%), group IV "viral and bacterial acute gastroenteritis" (90 patients, 20.4%), group V "peptic ulcer and gastroduodenitis" (66 patients, 14.9%), group VI "hepatobiliary and pancreatic disease" (14 patients, 3.2%), group VII "febrile viral illness and extraintestinal infection" (69 patients, 15.6%), group VIII "functional gastrointestinal disorder (acute manifestation)" (20 patients, 4.5%), and group IX "unclassified acute abdominal pain" (63 patients, 14.3%). Four patients were enrolled in two disease groups each. CONCLUSION: Patients were distributed unevenly across the nine groups of acute abdominal pain. In particular, the "unclassified abdominal pain" only group was not uncommon. Considering a systemic classification for acute abdominal pain may be helpful in the diagnostic approach in children.

Contributing Factors Analysis for the Changes of the Gross Motor Function in Children With Spastic Cerebral Palsy After Physical Therapy

OBJECTIVE: To investigate the factors which contribute to the improvements of the gross motor function in children with spastic cerebral palsy after physical therapy. METHODS: The subjects were 45 children with spastic cerebral palsy with no previous botulinum toxin injection or operation history within 6 months. They consisted of 24 males (53.3%) and 21 females (46.7%), and the age of the subjects ranged from 2 to 6 years, with the mean age being 41+/-18 months. The gross motor function was evaluated by Gross Motor Function Measure (GMFM)-88 at the time of admission and discharge, and then, the subtractions were correlated with associated factors. RESULTS: The GMFM-88 was increased by 7.17+/-3.10 through 52+/-16 days of physical therapy. The more days of admission, the more improvements of GMFM-88 were attained. The children with initial GMFM-88 values in the middle range showed more improvements in GMFM-88 (p<0.05). The children without dysphagia and children with less spasticity of lower extremities also showed more improvements in GMFM-88 (p<0.05). CONCLUSION: We can predict the improvements of the gross motor function after physical therapy according to the days of admission, initial GMFM-88, dysphagia, and spasticity of lower extremities. Further controlled studies including larger group are necessary.

A third stage pelvic organ prolapse due to cervical swelling during labor: A case report / 대한산부인과학회지

Pelvic organ prolapse complicating pregnancy is a rare clinical condition and its incidence is one in 10,000~15,000 deliveries. It is associated with multiparity, low socioeconomic status, inadequate perinatal care, maternal malnutrition, previous abdominal surgery, and weakness of pelvic muscular and connective tissue. It can cause cervical dystocia, which leads to cervical laceration, uterine rupture, maternal and fetal death. We experienced a case, first in Korea, of cervical swelling that developed during labor, prolapsed beyond the vaginal introitus and thus obstructed the birth canal. The patient underwent cesarean section and subsequently received MgSO4 topical therapy and resulted in complete resolution. We report this case with a brief review of literature.

A case of Bartter syndrome type I with atypical presentations / 소아과

Bartter syndrome (BS) is an autosomal recessively inherited rare renal tubular disorder characterized by hypokalemic metabolic alkalosis and hyperreninemic hyperaldosteronism with normal to low blood pressure due to a renal loss of sodium. Genetically, BS is classified into 5 subtypes according to the underlying genetic defects, and BS is clinically categorized into antenatal BS and classical BS according to onset age. BS type I is caused by loss-of-function mutations in the SLC12A1 gene and usually manifests as antenatal BS. This report concerns a male patient with compound heterozygous missense mutations on SLC12A1 (p.C436Y and p.L560P) and atypical clinical and laboratory features. The patient had low urinary sodium and chloride levels without definite metabolic alkalosis until the age of 32 months, which led to confusion between BS and nephrogenic diabetes insipidus (NDI). In addition, the clinical onset of the patient was far beyond the neonatal period. Genetic study eventually led to the diagnosis of BS type I. The low urinary sodium and chloride concentrations may be caused by secondary NDI, and the later onset may suggest the existence of a genotype-phenotype correlation.

Transient newborn neutropenia immediately after chemotherapy during pregnancy: A case report / 대한산부인과학회지

The incidence of acute leukemia in pregnancy is as low as 1 in 75,000 pregnancies. There is no established guideline for the treatment of leukemia during midtrimester pregnancy. But nowadays, consensus is not to delay the leukemia treatment with chemotherapy even in pregnancy. Many authors reported successful outcomes of mothers and newborns. Because of the leukemia itself and side effects of the chemotherapy, anemia, thrombocytopenia and neutropenia are commonly encountered in women treated with chemotherapy. With chemotherapy in utero just before the delivery, the newborn could be neutopenic. We report one case of midtrimester pregnant woman who took chemotherapy for leukemia and suffered from neutropenic fever and preterm labor. The newborn was neutropenic. However, both the mother and the baby were successfully recovered from neutropenia.

A variant of complete septate uterus with double cervix and vagina: A case report / 대한산부인과학회지

Rare mullerian anomalies without any present classification were sometimes reported. A 30-year-old nulligravid woman was referred to our hospital with 2-year history of primary infertility. Laparoscopic examination revealed a relatively intact uterine fundus with both patent fallopian tubes. Hysteroscopic exam confirmed the presence of double vagina and cervix, as well as complete uterine septum with opening at the lower segment. Hysteroscopic septotomy was successfully performed through the right-sided cervix. A variant of complete septate uterus with double cervix that communicated at the isthmic portion could be successfully treated by hysteroscopic operation.

Current Status and Activation Plan of Hospice Palliative Care in Korea - Based on Hospice Palliative Care Facilities Survey / 한국호스피스완화의료학회지

PURPOSE: This study aimed to evaluate the current status of hospice palliative care facilities in Korea. Based on the result, we attempted to suggest activation plans of hospice palliative in Korea. METHODS: To conduct a survey, we obtained a list of hospice palliative care facilities from related agencies and academic societies. A survey was conducted from February, 2009 to March, 2009. The survey was consisted of general characteristics of organizations, manpower, facilities & equipments, and so on. In addition, we used data from Statistics Korea to estimate the number of beds required and the bed occupancy rate. RESULTS: Total number of facilities responded to the questionnaire were 53. Forty-two facilities were general hospitals and 6 facilities were clinics among the total 53 facilities, and 18.8% of facilities were located in Seoul, Incheon and Gyeonggido. Overall bed occupancy rate was rather low as 21.9%, and there were 4 provinces where bed occupancy rates were 0%. Deaths in hospice palliative care facilities during 2008 were 6.3% of total deaths from cancers. As for the questions about the financial status of facilities, 86% of facilities were answered financial insufficiency. Also more than half of the facilities gave financial insufficiency as the reason for shortage of human resource supplies and inability to achieve the standard for authorization by the government. Facilities answered in order to activate the hospice palliative care, governmental support is needed, mostly in financial support (71.2%), donation tax deduction (43.1%), and setting up a public utility foundation (23.5%). CONCLUSION: This study showed low rates of hospice palliative care use and bed occupancy in Korea. Regional variance in bed occupancy rate was significantly high. As a roadblock for these problems, most of the facilities cited financial insufficiency. Therefore, there must be some action plans to boost financial support to activate hospice palliative care in Korea. Finally, efforts to improve these circumstances including lack of understanding about hospice and palliative care, are needed as well.

Clinical Characteristics and Associated Anomalies in Children with Solitary Kidney

PURPOSE: The clinical characteristics and associated anomalies in children with solitary kidney (SK) were analyzed retrospectively. METHODS: Total 38 children diagnosed to have SK at our hospital between December 1989 and December 2009 were recruited, and the clinical records including imaging studies were retrospectively reviewed. SK was defined as unilateral renal agenesis by imaging studies only, and patients with regression of unilateral dysplastic kidney were excluded. RESULTS: Among total 38 patients, 12 were male. The median age at the diagnosis of SK was 6.5 months (at birth-13 years). SK was detected by prenatal ultrasonography in 14 patients and during work-up for renal or urinary tract diseases in 13 (including urinary tract infection in 7). In 10 patients, SK was detected incidentally. Anomalies in the SK were noted in 17 patients including vesicoureteral reflux in 11. Other anomalies in the genitourinary tract were present in 16 patients, and multi-organ-involving syndromes or chromosomal anomalies were detected in 9. The mean duration of follow-up was 9 years (9 months-20 years). Two patients developed chronic renal failure during follow-up, and the median serum creatinine concentration of the remaining 36 at their last follow-up was 0.6 mg/dL. CONCLUSION: SK may be isolated and clinically asymptomatic; it is frequently accompanied by other anomalies in genitourinary tract and other organs, some of which can induce progressive renal dysfunction. Early recognition of associated anomalies with SK and regular follow-up is recommended to reduce long-term risk.

Relationship between Fatty Liver and Osteoporosis in Postmenopausal Women

BACKGROUND: The objective of the current study was to evaluate the association between fatty liver and osteoporosis in Korean postmenopausal women. METHODS: We examined postmenopausal women who participated in a health screening test from April 2004 to November 2007. Data about lifestyle and current medical diseases and medications were collected from medical records and medical interviews. Body weight, height, waist circumference and blood pressure were measured. Bone mineral density (BMD) was measured by dual- energy X-ray absorptiometry and body composition analyzer and abdominal ultrasonography were conducted for each participant. RESULTS: One thousand two hundred forty-five postmenopausal women were selected for this study. In postmenopausal women, the spine BMD levels (g/cm(2)) were significantly different in each subjects with normal (0.819+/-0.004), mild (0.846+/-0.007), moderate (0.844+/-0.009) and severe (0.779+/-0.031) fatty liver adjusted for age (P<0.01). The proportion of osteoporosis were significantly different in each subjects with normal (39.1%), mild (30.3%), moderate (31.6%) and severe (56.3%) fatty liver. A multiple logistic regression analysis was performed to determine the association between fatty liver and osteoporosis after age, body mass index, smoking, alcohol drinking and regular exercise. In severe fatty liver compared to the normal subjects of fatty liver, adjusted odds ratio was 3.6 (95% CI 1.2~10.9). CONCLUSION: In severe fatty liver disease, the proportion of osteoporosis was increased and the bone mineral density was lower than the normal subjects of fatty liver.

A Case of Metastatic Signet Ring Cell Carcinoma ofthe Colon in a Child / 대한소아소화기영양학회지

Colorectal carcinomas are extremely rare in childhood and adolescence; however, the colon is the most common site of a gastrointestinal carcinoma. Mucin secreting adenocarcinomas with signet ring formation is the most common type of colon cancer identified in children. An 11-year-old boy had abdominal pain and weight loss for three months, back pain and left thigh pain for two months, and hematochezia for four days. Colonoscopy showed an annular mass in the sigmoid colon and the histopathology revealed a signet ring cell carcinoma. A metastatic signet ring cell carcinoma was suspected from the findings of the bone scan, and confirmed later by a left scalp mass incisional biopsy and a bone marrow biopsy. We report a case of a metastatic signet ring cell carcinoma of the colon in a child.

Serum gamma-GT and Hypertension

BACKGROUND: We analyzed the data obtained from regular health checkups performed in a university hospital and investigated the effect of serum gamma-GT on hypertension for both Korean males and females. METHODS: A total of 3,288 adult males and females over 20 years of age were selected for this study who visited a health promotion center from April, 2004 to April, 2005. Patients with HBs Ag (+) or anti-HCV Ab (+) and those currently on medication that could affect hepatic function were excluded. The subjects' history of illness and their present health and medication status were examined through questionnaires and history taking. Also, basic physical examinations and laboratory tests were performed on these subjects. RESULTS: Classifying the serum gamma-GT into quartiles, as the gamma-GT classification stage increased, there was an increase in the amount of smoking, alcohol, body mass index, waist circumference, systolic blood pressure, diastolic blood pressure, fasting glucose, total cholesterol, triglyceride and low density lipoprotein for males or female (respectively, P for trend <0.01). When odd ratio (95% CI) for hypertension in the highest quartile of gamma-GT was compared to that of the lowest quartile, there was an increased risk of hypertension with an odd ratio of 1.6 (95% CI, 1.0~2.3) and 1.6 (95% CI, 1.0~2.4) for males and females, respectively. CONCLUSION: This study showed that the risk of hypertension was increased according to serum gamma-GT, even though the variable index affecting cardiovascular diseases was adjusted.

Clinical study on therpeutic effects of Guided tissue regeneration by Nanogide-C(R) and Biomesh(R) in furcation defects / 대한치주과학회지

This study was designed to compare the effects of treatment using chitosan membrane (Nanogide-C(R)) resorbable barrier with control treated by polylactic acid/polylacticglycolic acid membrane(PLA/PLGA membrane, Biomesh(R)). 44 furcation defecs from 44 patients with class 2 furcation degree were used for this study, 22 sites of them were treated by chitosan membrane as experimental group and 22 site were treated by PLA/PLGA membrane as control group. Clinical parameters including probing depth, gingival recession, attachment level and radiographic examination were evlauated at base line, 1 month, 2 month and 3 month. after surgery. Statistical test used to analyze these data included paired t-test, one way ANOVA. The results are as follows : 1. Probing depth was significanlly decreased in the two group and there were significant differences between groups(p<0.05). 2. Gingival recession was not significanlly increased in the two group and there were no significant differences between groups(p<0.05). 3. Loss of attachment was statistically decreased in the two group and there were no significant differences between groups(p<0.05). 4. Horizontal bone level was significanlly increased in the two group and there were significant differences between groups(p<0.05). On the basis of these results, chitoans resorbable membrane has similar potential to PLA/PLGA membrane in GTR for furcation defect.

The Effect of Brief Intervention on Heavy Drinking Patients in Primary Care

BACKGROUND: The management of problem drinking is very important in family practice and primary care. This research was de signed to evaluate the effect of brief intervention on heavy drinking patients in family practice. METHODS: The subjects were composed of 34 Korean males who had findings of alcoholic liver disease in the general health examination. About 5 to 10 minute outpatient interventions consisting of brief advice on drinking problems were delivered in the mean (+/-SD) f requency of 3.5 (+/-1.4) times during the 12 weeks.The effect of brief intervention was evaluated by the number of drinking days per week and drinks per drinking day during the 4 weeks before brief intervention and 12 weeks later.The result was compared with the control group (24 males)who had the same condition but did not receive the brief intervention. RESULTS: The mean (+/-SD)drinking days per week were significantly (P<0.001)decreased from 3.5 (+/-1.7) to 2.0 (+/-2.1) days and the mean (+/-SD) drinks per drinking day were significantly (P<0.001) decreased from 9.5 (+/-3.5) to 5.1 (+/-4.3) drinks.The degree of decrease in the subjects was significantly higher than the control group in both drinking days per week (P=0.001) and drinks per drinking day (P<0.005). CONCLUSION: The brief intervention by family physicians is an effective clinical method in the management of heavy drinking patients.

Carboxypeptidase-G2 Rescue in a Patient with High Dose Methotrexate-induced Nephrotoxicity / Journal of the Korean Cancer Association, 대한암학회지

A 13 year-old girl with osteosarcoma and pulmonary tumor recurrence developed acute renal failure following high dose methotrexate (12 g/m2) therapy, she had previously tolerated high dose methotrexate and her renal and hepatic functions were normal. Briefly, 48 hours after beginning methotrexate infusion her methotrexate concentration and creatinine level were 1338.8microM/L and 5.8 mg/dl, respectively. Grade IV oral mucositis and neutropenia with fever developed at 144 hours after MTX infusion. Hydration and alkalinization were continued and leucovorin rescue was intensified based on the plasma MTX concentrations. Plasma exchange was performed twice and hemodialysis 3 times without problems, but methotraxate and creatinine levels remained high, 91.9 microM/L, and 2.5 mg/dl, respectively. After 3 courses of hemodialysis carboxypeptidase-G2 (CPDG2) was administered at 50 U/kg, intravenously over 5 minutes. After 15 minutes of CPDG2 (Voraxaze(TM)) infusion, her plasma MTX concentration was 0.91microM/L and no rebound elevation or side effects developed. Thirteen days post-MTX infusion her renal function had normalized. We report here our experience of a dramatic methotrexate level reduction caused by CPDG2 administration.

Depression Level among Family Caregivers of Terminal Cancer Patients

BACKGROUND: As the importance of the quality of life is emphasiged in our society, efforts to improve the quality of life in the field of medicine have intensified. Terminal cancer patients, facing death, need not only biomedical therapy, but also systematic and continuous treatments such as mental or psycho-social intervention. The purpose of this study was to investigate the family caregiver's depression level and the associated factors. METHODS: The survey was conducted with 52 family caregivers of the terminal cancer patients who had been hospitalized at Chungnam National University Hospital from October 2003 to June 2004. The questionnaire consisted of the general characteristics of the subjects, BDI (Beck's Depression Inventory) evaluating the depression level and family APGAR score evaluating the family function. RESULTS: The mean age of the subjects was 50.4 years. The relationship with patients as 'spouse' accounted for 30 individuals (57.7%). The mean (+/-SD) BDI score was 24.0 (+/-10.9) points and 57.7 percent of the subjects were suggested to have depression tendency (> or =21 point). There was no relationship between the caregiver's depression level and their gender, religion, household income and family APGAR score. However, the depression level was significant related to the total caregiving duration (P=0.001), visiting frequency of visitors (P=0.004) and caregiving hours per day (P= 0.005). CONCLUSION: More than half of the family caregivers were suggested to have depression tendency. The depression level as influenced by the burden of caregiving and the visiting frequency of visitors. There is a need to activate social resources to share the burden of caregiving and to develop continuous and comprehensive care for terminal cancer patients and their families.

Nutritional Risk and its Related Factors Evaluated by the Mini Nutritional Assessment for the Elderly who are Meal Service Participants

This study is designed to assess the prevalence at risk of malnutrition according to the Mini Nutritional Assessment(MNA) and evaluate the factors influencing on the nutritional risk of the elderly. Three hundred and nine elderly (110 men and 199 women: mean age = 74.1) who participated in meal service in the Chung-buk province were investigated. Mean MNA total score was 21.9 and women had significantly lower MNA scores than men (respectively, 21.5 and 22.8). In the mean time mean MNA-SF (Short Form) score was 10.7, respectively 10.6 for the women and 11.0 for the men, with the difference being statistically significant. The MNA classified 33% of the elderly as well-nourished, 61.7% as at risk of malnutrition and 5.3% as overt malnourished. However, MNA-SF categorized the examinees 40.2% as good and 59.8% at nutritional risk. Those who identified as malnourished elderly had significantly lower mean BMI, mid-arm and calf circumference, poorer functional abilities (ADL, IADL), lower MAR and food habits scores, and higher number of nutrient < or = 75% of RDA than those with at risk of malnutrition and well nourished. Also socioeconomic status such as educational level, self-rated economic status, poverty level, and marital status significantly influenced nutritional status. Similar effect was observed in self-rated nutritional status and health status, dental status, appetite change according to MNA score. Stepwise multiple regression analysis indicated that weight loss was the most predictive item in the total MNA and MNA-SF score. It was found that items such as mobility, living status (home vs institution), mode of feeding, and pressure sores were inappropriate for assessment of the elderly who are able to participate meal service program. Also, some modifications of items in MNA are needed in order to apply to Korean elderly. Even though the MNA seems to be an useful tool to screen those old people at risk of malnourished, a lot of work is still to be done with this assessment tool to secure its reliability.

Rapidly progressive glomerulonephritis associated with infective endocarditis: a dramatically improved case after plasmapheresis / 대한내과학회지

A 28-year-old woman was admitted due to fever, dyspnea, hematuria and acute renal insufficiency. 1 months ago, she had been diagnosed as having ventricular septal defect with mild dyspnea and chronic cough. Infective endocarditis (IE) was diagnosed by clinical findings including vegetation in echocardiography. A blood culture drawn during the hospitalization grew streptococcus sanguis. A renal biopsy showed IE-induced crescentic glomerulonephritis (GN). Antibiotic treatment alone was effective for fever, but not for gross hematuria and renal insufficiency. After the initiation of plasmapheresis, gross hematuria and acute renal insufficiency was dramatically improved. After clinical stability was achieved, closure of the ventricular septal defect was performed. This result suggests that plasmapheresis may be beneficial in the treatment infective endocarditis-induced crescent GN.
