Background: Adverse drug reactions (ADRs) to first-line anti-tuberculosis (TB) drugs are common; however, there have been few reports of nationwide epidemiologic studies on ADRs to anti-TB drugs in Korea. This study aimed to investigate the clinical characteristics of various ADRs to first-line anti-TB drugs using a nationwide database of ADRs. Methods: We used the Korea Adverse Event Reporting System (KAERS) database (2009– 2018). The study subjects were selected using the Korean Standard Classification of Diseases codes for pulmonary and extrapulmonary TB and electronic data interchange codes for isoniazid (INH), rifampicin (RIF), ethambutol (ETB), and pyrazinamide (PZA). The causality assessment of “possible,” “probable,” or “certain” by World Health Organization-Uppsala Monitoring Center System causality category was selected. Results: A total of 1,562,024 ADRs were reported in the KIDS-KAERS database from 2009 to 2018, where ADRs to first-line anti-TB drugs were 17,843 cases (1.14%). The most common causative drugs were RIF (28.7%), INH (24.0%), ETB (23.4%), and PZA (23.9%) in that order. 48.5% of cases were reported in the older patients (≥ 60 years). According to organ system, gastro-intestinal system disorder was most common (32.0%), followed by skin and appendage (25.9%), liver and biliary system (14.2%). Nausea was the most common ADR (14.6%), followed by hepatic enzyme elevation (14.2%), rash (11.7%), pruritus (9.1%), vomiting (8.9%), and urticaria (4.2%). Most ADRs appeared within 1 month, but ADRs such as neuropathy, paresthesia, hematologic abnormalities, renal function abnormalities and liver enzyme abnormality were also often reported after 2 months. Conclusion: Our data are clinically informative for recognizing and coping with ADRs of antiTB drugs.

Background Latent tuberculosis infection (LTBI) has a high prevalence of around 25% worldwide. However, there are very few studies on adverse drug reactions to anti-TB drugs for LTBI. Objective: This study aimed to investigate clinical characteristics of various ADRs to anti-TB drugs in LTBI using a nationwide database of ADRs. Methods We used the Korea Adverse Event Reporting System (KAERS) database (2016-2019). The study subjects were selected using International Classification of Diseases (ICD) codes for LTBI and Electronic Data Interchange (EDI) codes for Isoniazid (INH), Rifampicin (RIF). The causality assessment of ‘possible’, ‘probable’, or ‘certain’ by WHO-UMC causality category was selected. The data were analyzed using R.4.0.2. Results A total of 499 cases were found from 371 ADR reports to INH and/or RIF in LTBI treatment. Male was 106 (21.2%), female was 205 (41.1%), and 136 cases (36.7%) were more than 50 yrs. According to treatment type, the frequency of ADRs was most common in INH/RIF (160); followed by INH (115), and RIF (96). According to organ system, liver and biliary system disorder was most frequent in INH (88/115, 76.5%), and in INH/RIF (100/160, 62.5%). However, skin and appendages disorders are most common in RIF (47/96, 49%). Rate of discontinuation was highest at RIF (46/96, 70%) followed by INH/RIF (57/160, 35,6%), and INH (49/160, 30%). The main cause of discontinuation was hepatic function abnormality in INH and INH/RIF while skin reactions in RIF. According to the time of ADR occurrence, gastrointestinal and skin symptoms appeared within one month, but hepatic dysfunction were occurred after three months in all regimens. Conclusions Information about ADRs in LTBI especially according to different regimen will be clinically informative to recognize and cope with ADRs of LTBI treatment.
An unexpected association between the blood bilirubin level and eosinophil count
( Soo Jie Chung ),( Suh-young Lee ),( So-hee Lee ),( Sun Sin Kim ) 대한천식알레르기학회 2023 Allergy Asthma & Respiratory Disease Vol.11 No.3
Purpose: Little is known about blood markers related to eosinophils in healthy individuals. We aimed to identify blood markers from routine tests associated with blood eosinophil count (BEC) in healthy individuals. Methods: Based on the complex interactions among blood markers, we used comprehensive analysis methods (regression, Bayesian network [BN], and partial correlation) and a health check-up database. To test consistency, we repeated the analysis using data from 3 check-ups of the same healthy individual. Results: A total of 12,625 individuals were enrolled in this study. Four groups were defined according to sex and smoking status: nonsmoking men (n=1,737), smoking men (n=6,518), nonsmoking women (n=3,995), and smoking women (n=375). The blood bilirubin and γ-glutamyltransferase levels showed significant associations with BEC by regression analysis. However, BN analysis found that only the bilirubin node was directly connected to the BEC node. By partial correlation analysis, the blood bilirubin level showed significantly negative association with BEC. The same results were obtained across all the 3 health check-ups, except in smoking women. In addition, a lower blood bilirubin level predicted a significantly elevated BEC (especially ≥200/μL). The blood bilirubin levels measured at 3 time-points were significantly associated with BEC in men and nonsmoking women. Conclusion: The blood bilirubin level, which is easily obtained by routine test in clinical practice, may be a useful marker for BEC. (Allergy Asthma Respir Dis 2023;11:151-160)

Purpose: Food-dependent exercise-induced anaphylaxis (FDEIA) is a rare subtype of food allergy in which both sensitization to food allergen and exercise as a trigger contribute to its development. However, its pathogenesis is still under investigation. This study compared clinical features, the causative foods, and the degree of sensitization to food between FDEIA and food anaphylaxis to characterize FDEIA more clearly. Methods: We retrospectively reviewed the medical records of patients who were diagnosed with FDEIA (n=89) or food anaphylaxis (n=115) between 2003 and 2015 at Seoul National University Hospital. Results: Subjects with FDEIA more frequently had urticaria than those with food anaphylaxis (88.8% vs. 76.5%, P=0.024). Whereas patients with FDEIA had less laryngeal edema than those with food anaphylaxis (12.4% vs. 30.4%, P=0.02). Wheat (67.4%) was the most common causative food allergen in FDEIA, whereas seafood (40.9%) was the most common culprit food allergen in food anaphylaxis. Also, subjects with FDEIA showed a lower atopic index score than those with food anaphylaxis (0.55±1.07 vs. 1.21±1.82, P=0.006). Conclusion: There were significant differences in clinical manifestation, causative food allergens and the degree of sensitization to food between FDEIA and food anaphylaxis.

Background: This study was done to compare vacuum delivery and cesarean section rates in a large population before and after on-demand labor epidural analgesia became available. Methods: We retrospectively investigated the overall sets of delivery modes in patients who gave birth during a 12-month period before the introduction of on-demand labor epidural analgesia, and those giving birth after labor epidural analgesia became available. Additionally, we compared the rates of cesarean section or vacuum delivery in patients delivering before and after the availability of on-demand labor epidural. Results: Included were 3905 patients who delivered before, and 4318 patients who delivered after epidural analgesia became available. Labor epidural rates were 0.3% vs 14.7% for the before and after groups. The rates of cesarean delivery for dystocia in primary cesarean operation did not change (10% vs 10.5%), and vacuum delivery rates in the total vaginal delivery patients were not changed (15.1% vs 14.7%) for the before and after group. Conclusions: Increased epidural analgesia did not change the overall cesarean delivery rates for dystocia and vacuum - assisted delivery rates. (Korean J Anesthesiol 1999; 37: 52∼56)

Exiguobacterium sp. 유래의 β-glucosidase 고정을 위하여 글루타르알데하이드를 사용한 키토산 비드를 조제하였다. 키토산 비드의 교차결합 및 고정화의 조건을 최적화하였다. β-glucosidase 고정화의 최적생산 조건에서 20%의 수율과 5.22 U/g의 효소활성을 나타냈다. 최적 pH 와 온도는 9.0과 55°C를 나타냈다. 고정된 효소의 안정성은 pH 7.0-10.0에서는 80%, 40°C 2시간 반응에서는 80% 및 50°C 1시간 반응에서는 48%의 활성을 보유하였다. 이러한 결과는 높은 pH와 고온에서 비고정 효소보다 안정성을 보여주었다. 고정된 효소를 가지고 대두 이소플라 본 배당체의 높은 가수분해능을 확인하였다. 이상의 결과는 고정화 효소의 다양한 이용 가능성을 시사하였다. Glutaraldehyde was used to cross-link chitosan beads to immobilize the crude enzyme β-glucosidase from Exiguobacterium sp. DAU5. The conditions for preparing cross-linking chitosan beads and immobilization such as concentration of glutaradehyde, cross-linking time, immobilization pH and time were optimized. The chitosan beads were cross-linked with 1.5% glutaraldehyde for 1.5 hr. The immobilized β-glucosidase had an overall yield of 20% and specific activity of 5.22 U/g. The optimized pH and temperature were 9.0 and 55°C, respectively. More than 80% of its activity at pH 7.0-10.0, 80% at 40°C for 2 hr and 48% at 50°C for 1 hr, were retained. However, the immobilization product showed higher pH and thermal stabilities than free enzymes. It also showed high hydrolyzing activity on soybean isoflavone glycoside linkage. These results suggest the broad application prospects of immobilization enzymes.

The spinal traumas in children are rare and exhibit different features other than in adults. We treated the 51 cases of pediatric spinal trauma in total 2624 spinal traumas during 19 years(from Jan. 1973 to Dec. 1991). The review of these pediatric cases was done. They showed higher cervical injury. higher incidence of SCIWORA(spina1 cord injury without radiographic abnormality) in more younger patients. The outcome after pediatric spinal trauma is relatively good.
