연구배경: 다제내성결핵 치료에서 감수성으로 증명된 1차 항결핵제는 가장 항결핵효과가 큰 약제로 알려져 있다. 본 연구는 다제내성결핵 환자에서 표준 1차 항결핵제사용 후 1차 항결핵제에 대한 추가 내성 획득의 빈도와 그 위험 인자를 알아보고자 시행되었다. 방 법: 2004년 1월에서 2008년 5월까지 국립마산결핵병원에서 약제감수성 검사가 보고되기 전 표준 1차 항결핵제로 치료받은 다제내성결핵 환자 중에서 1차 항결핵제 치료 전과 1차 항결핵제 치료 후의 연속된 두 시점의 약제 감수성 검사 결과가 모두 있는 환자를 대상으로 하여 의무기록을 후향적으로 검토하였다. 결 과: 표준 1차 항결핵제로 치료 받은 41명 중 14명 (34.1%)에서 ethambutol (EMB) 혹은 pyrazinamide (PZA)에 대한 추가 내성이 획득되었다. 치료 전 isoniazid (INH), rifampicin (RFP)에만 내성을 보였던 11명 중 3명(27.3%)에선 EMB와 PZA에 동시 내성, 3명(27.3%)에선 PZA에 추가 내성이 획득되었다. INH, RFP, EMB에 내성을 보인 18명 중 6명(33.3%)에서 PZA에, INH, RFP, PZA에 내성을 보인 6명 중 2명(33.3%)에서 EMB에 추가 내성이 획득되었다. 대상 환자 중 10명(24.4%)에서 1차 항결핵제 치료 전 내성이었던 약제가 치료 후 감수성으로 전환되었다. 추가 내성획득과 연관된 통계학적으로 유의한 위험인자를 발견할 수 없었다. 결 론: 우리나라의 다제내성결핵 치료에서 1차 항결핵제는 추가 획득 내성의 위험을 고려하여 주의 깊게 사용해야 할 것으로 사료된다.

A 33-year old male was admitted due to continuous high spiking fever for 2 months via local clinic. He had been diagnosed pulmonary tuberculosis at local clinic. However, spiking fever had not been controlled by anti-tuberculous medications. Chest PA showed confluent consolidation on right upper & mid-lung field. 5 anti-tuberculous regimens(Streptomycin, Isoniazid, Rifampin, Ethambutol, Pyrazinamaide) were administered initially and steroid therapy was followed for relieving toxic symptoms Very slowly resolved chest X-ray lesion and continuous fever suggested the possibility of misdiagnosis. After 60th hospital day, the chest X-ray lesion was resolved gradually and fever subsided almost completely. He was discharged on 76th hospital day with anti-tuberculous drugs and steroid(prednisolon), without any other problems except sustained mild fever.

The drug reaction with eosinophilia and systemic symptom (DRESS) syndrome is a severe adverse drug-induced reaction which includes a severe skin eruption, fever, hematologic abnormalities (eosinophilia or atypical lymphocytes) and internal organ involvement. The most frequently reported drug was anticonvulsants. The diagnosis of DRESS syndrome is challenging because the pattern of cutaneous eruption and the types of organs involved are various. The treatments for DRESS syndrome are culprit drug withdrawal and corticosteroids. Here we report a 71-year-old man with skin eruption with eosinophilia and hepatic and renal involvement that appeared 4 weeks after he had taken anti-tuberculosis drugs (isoniazid, ethambutol, rifampicin, and pyrazinamide), and resolved after stopping anti-tuberculosis drugs and the administration of systemic corticosteroids. DRESS recurred after re-challenging isoniazid, we identified isoniazid was causative drug.

A Lactobacillus isolate was collected from the feces of a healthy Korean individual and named as Lactobacillus ruminus SPM0211. It was further characterized by subjecting it to an antibiotic resistance test and genetic analysis. In the antibiotic resistance test, all tested Lactobacillus spp. were classified as 'high resistance' for multiple antibiotics, such as isoniazid, ethambutol, cycloserine, and vancomycin. L. ruminus SPM0211 was classified as 'high resistance' for streptomycin also, while the other tested Lactobacillus spp. were classified as low resistance. This suggests that the antimicrobial spectra may be a good indicator in the discrimination of this strain among the tested Lactobacillus spp. In a polymerase chain reaction-random amplified polymorphic DNA (PCR-RAPD) analysis using the Microbial Uniprimer kit, L. ruminus SPM0211, and L. suebicus were clustered as a group with a 74.3% similarity level, suggesting that these two species are genetically related. Thus, our data suggest that the PCR-RADP method using the Microbial Uniprimer kit may be valuable in discriminating L. ruminus SPM0211 from other Lactobacillus spp.

Mycobacterium abscessus comprises rapidly growing mycobacteria, and the clinical manifestations of M. abscessus skin infection include papule, nodule, ulcer, scar and mixed form. The cutaneous infections have been reported due to minor trauma, cosmetic therapy, acupuncture and disseminated infection. A 75-year-old man presented with pruritic diffuse various sized erythematous papuloplaques and pustules on the neck and chest for 2 months. The cutaneous lesions were spread around the wound of the shaving on the neck. The histopathologic findings were consistent with abscess showing infiltrations of neutrophils and lymphocytes in the dermis and negative findings were observed on immunohistochemical stain including acid-fast bacilli stain. One month later, mycobacterial culture result showed positive findings, and the pathogen was identified by reversetranscriptase polymerase chain reaction with hybridization. The patient was treated with combination of clarithromycin and ethambutol for 5 months and there is no evidence of recurrence after 6 months of follow-up. Herein, we report a case of M. abscessus cutaneous infection through minor trauma caused by shaving in the elderly.

Miliary tuberculosis (TB) is a rare extrapulmonary form of TB, and there have been only two reports of miliary TB associated with infection with multidrug-resistant (MDR)-TB pathogen in an immunocompetent host. A 32-year-old woman was referred to our hospital because of abnormal findings on chest X-ray. The patient was diagnosed with MDR-TB by a line probe assay and was administered proper antituberculous drugs. After eight weeks, a solid-media drug sensitivity test revealed that the pathogen was resistant to ethambutol and streptomycin in addition to isoniazid and rifampicin. The patient was then treated with effective antituberculous drugs without delay after diagnosis of MDR-TB. To the best of our knowledge, this is the first case of miliary TB caused by MDR-TB pathogen in Korea.

Tuberculosis (TB) remains a threat to public health and is the leading cause of death globally. Isoniazid (INH) is an important first-line agent for the treatment of TB considering its early bactericidal activity. Resistance to INH is now the most common type of resistance. Resistance to INH reduces the probability of treatment success and increases the risk of acquiring resistance to other first-line drugs such as rifampicin (RIF), thereby increasing the risk of multidrug-resistant-TB. Studies in the 1970s and 1980s showed high success rates for INH-resistant TB cases receiving regimens comprised of first-line drugs. However, recent data have indicated that INH-resistant TB patients treated with only firs-tline drugs have poor outcomes. Fortunately, based on recent systematic meta-analyses, the World Health Organization published consolidated guidelines on drug-resistant TB in 2019. Their key recommendations are treatment with RIF-ethambutol (EMB)-pyrazinamide (PZA)-levofloxacin (LFX) for 6 months and no addition of injectable agents to the treatment regimen. The guidelines also emphasize the importance of excluding resistance to RIF before starting RIF-EMB-PZA-LFX regimen. Additionally, when the diagnosis of INH-resistant TB is confirmed long after starting the first-line TB treatment, the clinician must decide whether to start a 6-month course of RIF-EMB-PZA-LFX based on the patient's condition. However, these recommendations are based on observational studies, not randomized controlled trials, and are thus conditional and based on low certainty of the effect estimates. Therefore, further work is needed to optimize the treatment of INH-resistant TB.

Tuberculous cervical lymphadenitis is one of common cause of neck mass in young adult in Korea. Tuberculous cervical lymphadenitis known as scrofula was being treated by the 'Royal Touch' in the 5th century and by surgery in the 17th century, yet the principle of the treatment is still controversal. We report the clinical evaluation and therapeutic result about 121 tuberculous cervical lymphadenitis. The result were as follows: 1) The annual incidence(1985-1994) was 30.5 % (37 cases: 1985-1986), 17.7 % (21 cases: 1990-1992). 19.8%(24 cases: 1994). 2) The age of highest incidence was 20-29 year old age group in 41.3% (50 cases) and female predominated over male by 1.8 : 1. 3) The duration of disease was less than 6 months, in 85.9% (104 cases). 4) The most commonly involved LN group was superficial cervical group in 69.4% (84 cases), and difference between Rt & Lt, was not significant. 5) The most common symptom and local finding(P/E) were, painless swelling of LN in 74.3 % (90 cases) and single mass in 59.5 % (72 cases). 6) In seasonal variation, 85.9% (104 cases) was spring and summer. 7) Procedures except biopsy for evaluation were chest PA, AFB smear & culture(sputum), Mantoux test, USG, CT and, Associated extracervical tuberculous lesions were lung, axilla, breast. 8) In operation method (involving biopsy), Excision was 68.5 % (83 cases), neck dissection was 6.6% (8 cases). 9) The Modality, Duration and side effect of antituberculous medication: INH-Rifampin­Ethambutol was 66.1 % (88 cases), duration was 1 year in 84.3% (102 cases), side effects were severe GI trouble (24.8%), liver function damage (3.3%). 10) 3 cases recurred on the same site after 2 yrs(2 cases) and 4 months(1 case) and its treatment was curretage or I & D, with antituberculous medication.

Nontuberculous mycobacterial (NTM) diseases are increasing worldwide. However NTM lung disease in organ transplant recipients has been rarely reported. Here, we report 2 cases of NTM lung disease in heart transplant recipients. A 37-year-old man, who had undergone a heart transplant one year previous, was admitted to hospital due to a cough. Chest CT scan showed multiple centrilobular nodules in both lower lungs. In his sputum, M. abscessus was repeatedly identified by rpoB gene analysis. The patient improved after treatment with clarithromycin, imipenem, and amikacin. An additional patient, a 53-year-old woman who had undergone a heart transplant 4 years prior and who suffered from bronchiectasis, was admitted because of purulent sputum. The patient's chest CT scan revealed aggravated bronchiectasis; M. intracellulare was isolated repeatedly in her sputum. Treatment was successfully completed with clarithromycin, ethambutol, and ciprofloxacin. NTM lung disease should be considered as a potential opportunistic infection in organ transplant recipients.
