We report a 33-year-old man with AIDS dementia complex, which is one of the most common neurologic complica-tion of HIV-1 infection. The man presented with mild psychomotor slowing and episodic loss of consciousness about 5 years after the detection of the HIV-1 infection. His symptoms included forgetfulness, concentration difficulties, apathy, and psychomotor retardation which progressed rapidly evolving into the characteristic features of terminal HIV-1-asso-ciated dementia complex, such as severe dementia, mutism, incontinence, and paraparesis before death. Brain MRIrevealed diffuse confluent high signal intensity lesions in the subcortical white matter on the T2 weighted image. HIV encephalitis (AIDS dementia complex) was confirmed by a brain autopsy.

CYP2D6 is primarily responsible for the metabolism of clomiphene citrate (CC). The purpose of the present study was to investigate the relationship between CYP2D6 genotypes, concentrations of CC and its major metabolites and drug response in infertility patients. We studied 42 patients with ovulatory dysfunction treated with only CC. Patients received a dose of 100 mg/day CC on days 3-7 of the menstrual cycle. CYP2D6 genotyping and measurement of CC and the major metabolite concentrations were performed. Patients were categorized into CC responders or non-responders according to one cycle response for the ovulation. Thirty-two patients were CC responders and 10 patients were non-responders with 1 cycle treatment. The CC concentrations were highly variable within the same group, but non-responders revealed significantly lower (E)-clomiphene concentration and a trend of decreased concentrations of active metabolites compared to the responders. Nine patients with intermediate metabolizer phenotype were all responders. We confirmed that the CC and the metabolite concentrations were different according to the ovulation status. However, our results do not provide evidence for the contribution of CYP2D6 polymorphism to either drug response or CC concentrations.

PURPOSE: Molecular genetic analysis is the main approach used for prenatal diagnosis of hemophilia A and B. However, in certain cases, such analysis is uninformative. In such situations, direct measurement of fetal coagulation factor levels is still the best option, and it may be the only option in some cases. This study was conducted to determine the normal ranges of midtrimester cord blood factor VIII (FVIII) and IX (FIX) in a Korean population. MATERIALS AND METHODS: Twenty-six FVIII samples and 29 FIX samples were assayed in fetal cord blood acquired by ultrasound-guided cordocentesis. Sampling was conducted during gestational ages of 19-24 weeks. RESULTS: The mean and standard deviations for FVIII and FIX activity were 45.5±30.5% and 19.9±12.2%, respectively. Ranges for FVIII and FIX were 1.5-125.0% and 6.0-52.0%, respectively. CONCLUSION: Our study revealed the normal ranges and lowest level of factor VIII and factor IX in non-affected normal fetus by fetal cord blood sampling during the mid-trimester in a Korea population. The factor assay of the fetal cord blood is invasive but feasible and provides important basic data related to hemophilia.

PURPOSE: Total parenteral nutrition (TPN) has been widely used in malnourished, critically ill or surgical patients since the 1970's. However, short-term application of TPN after elective gastrointestinal surgery has rarely been studied. The purpose of this study was to evaluate the safety and efficacy of postoperative TPN in patients after gastrectomy. METHODS: Forty seven patients who underwent elective gastrectomy from October 2005 to December 2005 were enrolled in this trial. Twenty two patients (TPN group) received multivitamin-containing TPN (Fulcaliq(R), Terumo, Japan) and 25 patients (control group) received the usual 10% dextrose solution for five days after surgery. Vital signs, body weight and nutritional support-related complications were evaluated on a daily basis. In addition, CBC, LFT, electrolyte, and trace elements were measured four times (preoperatively, POD1, POD 3 and POD 6). RESULTS: Nutritional support-related complications did not develop in the groups studied. Body weight and serum albumin levels were not different in comparisons between the two groups. However, in the TPN group, the total protein level on POD 6 had a tendency to be higher than in the control group. On POD 6, AST and ALT levels were significantly higher in the TPN group, but the total bilirubin and cholesterol levels were significantly higher in the control group. CONCLUSION: Multivitamin-containing TPN appears to be safe and effective for patients, in the short term, after gastric surgery.

Cytomegalovirus(CMV) rarely causes cutaneous rnanifestations. But since the recent development of organ transplants and the increased prevalence of AIDS, various skin manifestations of CMV infection such as varicelliform eruptions, perineal hulcerations, papular, purpurc and vesiculobllous lesions are increasing in immunocompromised subjects, Perineal ulceration is a typical cytomegalovirus-induced skin manifestation which exhibits similar morphology to herpes simplex viral infection. We describe a case of CMV-induced ulcer on labia majora in an AIDS patient, proven by histologic findings and immunohistochemistry. The patient was treated with ganciclovir and the lesion improved two months later.

OBJECTIVE: We used nucleated erythrocytes in maternal blood for prenatal determination of the fetal gender as the preliminary experiment for the screening of fetal genetic status and the BclI DNA polymorphism in an attempt to clarify the origin of erythrocytes in maternal blood. METHODS: In seventeen pregnant women, venous blood was withdrawn and the nucleated erythrocytes were recovered by magnetic activated cell sorting (MACS) and immunostaining. After isolation of nucleated erythrocytes by micromanipulation, we performed nested PCR for amelogenin gene to identify the fetal gender and performed BclI DNA polymorphism to clarify the origin of erythrocytes. RESULTS: We could amplify the minute DNA in a single cell by primer extension preamplification and nested PCR of amelogenin gene in 94 (48.7%) cells and could identify the fetal gender by 58.8%. BclI DNA polymorphism revealed that the several cells, which did not reveal the specific band of Y chromosome in spite of the pregnancy of male fetuses, must be the cells from mother. CONCLUSION: Through this study, we could conclude that several nucleated erythrocytes in maternal blood circulation can originate from mother, therefore we must develop the new method to identify the nucleated erythrocyte of fetal origin. Considering that we must apply for the larger number of pregnant women to screen, the procedure was multi-step and complex. Therefore, we must design the new scheme to utilize the nucleated erythrocytes in maternal blood.

BACKGROUND: Although therapeutic plasmapheresis (TP) is a useful procedure in removing pathogenic antibodies and toxic substances from the patient, adverse reactions could arise from the use of replacement fluids and anticoagulants. Comprehensive analysis on those adverse effects had been rarely reported in Korea. METHODS: We retrospectively investigated the clinical records and the TP records from 3,962 TP sessions for 581 patients between January 1995 and October 2008 at Asan Medical Center, and we analyzed the adverse reactions related to TP. RESULTS: Adverse reactions were seen in 142 patients (24.4%) in 348 TP procedures (8.8%). Citrate toxicity was most frequently seen in 83 procedures (23.9%) followed by chills in 72 procedures (20.7%), allergic reactions in 69 procedures (19.8%) and hypotension in 60 procedures (17.2%). Citrate toxicity, chills and allergic reactions were seen more frequently in the TP procedures using FFP than in the TP procedures using albumin (P=0.001). The prevalence of citrate toxicity was significantly lower in the cases where calcium gluconate was administered (P<0.001), while it was significantly higher in the patients whose hematocrit was below 28.5% (P<0.001). In terms of severity, the mild, moderate and severe adverse reactions were 36.8%, 56.3% and 6.9%, respectively. CONCLUSION: TP is a relatively safe method of treatment, but it is important to predict and prevent adverse reactions and to respond appropriately to these adverse reactions.

There are still no agreed guidelines on the vaccination of coronavirus disease 2019 (COVID-19) for previously infected patients. Here, we present two seropositive healthcare workers (HCWs) working in an isolation ward who recovered from COVID-19 in April 2020 and got vaccinated with BNT162b2 vaccine in March 2021. We have assessed the clinical course, vaccine-related adverse events, and antibody response after natural infection and after first and second dose vaccination. One of the two HCWs was asymptomatic during quarantine, but the other had mild upper respiratory infection symptoms 1 day before admission, and the symptoms continued for 9 days. There was no pneumonic infiltration in chest X-ray in both patients, and no COVID-19 specific treatment was administered.Total immunoglobulin antibody and neutralizing antibody to anti-spike protein receptorbinding domain of severe acute respiratory syndrome coronavirus 2 were confirmed to be present in both HCWs in blood tests performed at 2 weeks and 4 weeks after discharge.Antibody response to mRNA vaccination showed marked elevation after the first vaccination, which was 30–40 times higher than that of antibody titer after natural infection in each patient (83.2 U/mL vs. > 2,500 U/mL in patient 1; 61.6 U/mL vs. > 2,500 U/mL in patient 2).Signal inhibition rate of neutralizing antibodies was also increased to over 97%. Due to this increased effect, there was little difference in antibody levels after the first and second dose. Both patients 1 and 2 suffered more from adverse vaccine reactions after the second vaccination than from COVID-19 symptoms.
