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.

An oxidimetric titrant, 2, 3-dichloro-5, 6-dicyano-1, 4-benzoquinone in anhydrous acetic acid is used for the semimicro-determination of hydrazine hydrate, phenylhydrazine hydrochloride, isoniazid and iproniazid phosphate in pure forms as well as in some pharmaceutical preparations containing isoniazid and iproniazid phosphate. The end point was detected potentiometrically using a platinum-calomel combination electrode. The results obtained are compared statistically with those obtained by the official methods and they are in good agreement.

A seven-month-old castrated male Chihuahua weighing 1.6 kg presented with generalized tonic-clonic seizure following ingestion of isoniazid. Emergency treatment with three doses of diazepam (total 1.5 mg/kg, intravenous [IV]) and phenobarbital (15 mg/kg IV) was administered. The seizure stopped after administration of propofol (constant rate infusion [CRI]; 0.2 mg/kg/min). Blood analyses showed mildly increased serum blood glucose concentration, hyperkalemia, and hyperphosphatemia. On suspicion of isoniazid toxicity, activated charcoal (1 g/kg, orally), lipid emulsion (CRI; 9 mL/hr), and pyridoxine hydrochloride (70 mg/kg IV) were added to the treatment regimen. Twelve hours after presentation, the dog showed increased serum liver enzyme activities, serum blood urea nitrogen, and creatinine concentrations indicating hepatic and renal failure. Twenty-two hours after presentation, blood analysis still revealed increased liver enzyme activities, blood urea nitrogen, and creatinine concentrations with low blood glucose concentration. Twenty-six hours after presentation, the dog's vital signs deteriorated and the owner elected for the dog to be euthanized. This is the first report of the clinical course of isoniazid toxicosis in a dog in South Korea. Furthermore, to our best knowledge, this is the first report where secondary multiple organ failure was observed due to isoniazid toxicosis. Clinicians should be aware of the possibility of isoniazid toxicosis in dogs. Rapid initiation of treatment after clinical recognition is warranted in such cases.

Regional lymphadenitis is the most common complication following BCG vaccination in this country. The literature describes controversial results with medical, surgical and combined therpy. The purpose of this study is to clarify the therapeutic effect of isoniazid(INH) after surgical procedures. The early and late postoperative complications of 136 children with lymphadenitis following BCG vaccination at the Taegu Fatima Hospital between March 1985 and February 1996 were reviewed. In 90 children, INH was given for 3-4 days before operation and for 3 months after surgery. In the other 46 cases, INH was not given during the pre- or postoperative period. Surgical procedures were excision or incision and currettage according to the states of lesions. Postoperative complications were fluid accumulation, wound infection, sinus formation and others. Complication rates were 14.4 % in INH-treated group and 13.0% of INH-nontreated group. The difference was not significant. There was no recurrence or other late complication in either groups. The result suggest that surgical excision or incision and currettage are sufficient for the treatment of regional lymphadenitis following BCG vaccination and postoperative INH therapy is not necessary.

Even though two different preparations are chemically equivalent, the variance of bioavailability differenciates the clinical effect of preparations, so that the preparations need to be evaluated by comparing bioavailability in vivo as well as chemical equivalence. In this study, bioequivalence tests of commercially available isoniazid tablets A, B, C and D (standard) were performed to give some guidelines to bioequivalence test. The bioavailability parameters obtained by drug administeration were statistically analyzed. Statistical evaluation of the data involved an analysis of variance for a cross over design. Cross over design was employed with 8 healthy volunteers. The results were within 20% difference of mean value in the AUC, Cmax, Tmax and amount of urinary excretion (Au) between standard and isoniazid tablets. The results of ANOVA showed no significant differences for 'group or sequence', but almost not for 'between subjects'. The tablet. A, B and D were within 20 min, but tablet C was within 50 min. Tablet A was biologically equivalent in the Au. tablet B biologically equivalent in the Au and AUC. Tablet C was biologically equivalent in the Au. The relationship between the dissolution rate and Au was significant.

Transient isoniazid-induced brain lesions have rarely been reported. The lesions were in the dentate nucleus of cerebellum and thalamus. Meanwhile, the neurotoxicity of rifampin has not been reported evidently. We observed bilateral lesions in the internal capsule in a young woman after taking a combination of isoniazid and rifampin. She transiently suffered numbness in both hands, dysarthria, and left side motor weakness while taking the medication. Isoniazid may induce structural lesions in various brain areas including the internal capsule.

연구배경 : Theophylline은 간세포내 cytochrome P-450 계열의 효소에 의해 거의 90% 정도 대사되는데, isoniazid, rifampicin 등 항결핵제틀은 미소체 효소계(microsomal enzyme system)에 영향을 미치어 theophylline과의 병용투여시 theophylline 대사에 변화를 일으킬수 있다. 방 법 : INH, RFP, EMB 및 PZA의 병합 요법이 theophylline의 약물동태에 미치는 영향에 대하여 Bayesian 방법을 이용하여 평가하였다. Theophylline을 투여중인 환자를 대상으로 3군으로 나누어, Group I를 대조군으로 하였으며, Group II는 INH, RFP, EMB 및 PZA를 병용 투여하였고, Group III는 INH, RFP 및 EMB을 병용 투여하였다. 모든 대상환자는 비흡연자로 간기능 및 신기능 검사상 정상 범위였으며 theophylline의 약물동태에 영향을 줄 수 있을 만한 약제를 복용한 환자는 제외하였다. 결 과 : 정상 대조군과 실험군들을 비교시, theophylline 소실률은 Group II와 Group III 모두 유의하게 감소하였으며(p<0.001), theophylline 반감기 역시 Group II와 Group III 모두 유의하게 증가하였다 (p<0.001). 그러나 Group II와 Group III간의 theophylline 소실률 및 반감기는 차이가 없었다. 결 론 : 이상의 결과로 INH, RFP 및 EMB 등의 항결핵제와 theophylline 병용 투여시 theophylline 용량의 재조정이 필요할 것으로 사료된다.

Early and accurate detection of drug resistant Mycobacterium tuberculosis can improve both the treatment outcome and public health control of tuberculosis. A number of molecular-based techniques have been developed including ones using probe molecules that target drug resistance-related mutations. Although these techniques are highly specific and sensitive, mixed signals can be obtained when the drug resistant isolates are mixed with drug susceptible isolates. In order to overcome this problem, we developed a new drug susceptibility test (DST) for one of the most effective anti-tuberculosis drug, isoniazid. This technique employed a microplate hybridization assay that quantified signals from each probe molecule, and was evaluated using clinical isolates. The evaluation analysis clearly showed that the microplate hybridization assay was an accurate and rapid method that overcame the limitations of DST based on conventional molecular techniques.

소아에서 약물 유발성 독성 간염은 비교적 흔하며 대부분 약을 끊으면 호전된다. 특히 항결핵약은 주요 유발 약물이다. 약물 유발성 독성 간염은 자가면역질환을 동반할 수 있으며, 이러한 원인으로 보고된 약제로는 주로 methyldopa, nitrofurantoin, minocycline, interferon 등이고, 항결핵약 보고는 드물다. 저자들은 갑상선염이 동반되고 항결핵약 isoniazid와 rifampin으로 유발된 약물 유발성 자가면역간염을 경험하였기에 국내에서 처음으로 문헌고찰과 함께 보고하는 바이다.

구리수은막 전극(CBMFE)으로 전위차 역적정함으로써 이소니아자이드(INH)를 정량하는 간단하고 빠른 방법이다. 순수한 형태와 투약형태에 대해서 1.0-10.0 mg 범위에서 정량 할 수 있도록 적정조건을 설정하였다. 방법의 정밀도와 정확도는 통계적인 방법으로 평가되었으며, 정제와 시럽속에 함유된 INH 정량법은 F-시험과 t-시험을 통하여 영국약전(BP) 방법과 비교하였다.
