Background: Pulmonary tuberculosis (TB) is still common disease among the elderly patients in Korea where the overall incidence of TB is decreasing. Adverse drug reactions (ADR) associated with anti-TB drugs occurs frequently. Especially the aged tends to have more frequent ADRs than younger ones. These ADRs can cause significant morbidity, compromise therapeutic effects of drugs and even induce drug resistance. Therefore we evaluated the effect of ADRs on the first-line anti-TB drugs in elderly patients with active pulmonary TB. Methods: We retrospectively reviewed the charts and radiological findings of the patients with 65 and older who were bacteriologically confirmed as active TB and treated with standard anti-TB drugs for at least 6 months. Major ADR was defined with temporary or continuous stop of any first-line drugs intake. Results: An ADR was noted in 54% of all patients. The incidence of major ADR was 32% in all elderly patients. Dermatologic ADR (9%) was the most common among the major ADRs. GI trouble (8%), arthralgia (6%), visual change (6%), hepatotoxicity (4%), and fever (1%) were also noted. The drugs responsible for major ADR were ethambutol (62%), pyrazinamide (35%), rifampin (18%) and isoniazid (9%). Major ADRs were associated with higher ESR level at the initiation of anti-TB drugs. Conclusion: First-line anti-TB drugs in elderly patients frequently caused the major ADRs. Therefore the elderly patients receiving anti-TB drugs should be closely monitored and better tolerable therapy should be considered as part of a TB research agenda.

목적: 일차성 야뇨증에 여러 가지 치료법이 시도되고 있는데 이 중 일반적으로 사용되는 imipramine와 desmopressin 등의 약물요법은 치료효과가 빠르고 비교적 양호하기 때문에 선호하는 치료 방법이다. 그러나 효과가 매우 다양하고 때로는 약물에 의한 부작용으로 인해 사용이 어렵게 되는 경우도 있다. 본 연구에서는 이들 약물을 단독으로 투여한 경우에 비하여 복합투여 할 경우에 치료 효과와 안정성을 비교 평가하여 보다 나은 야뇨증 치료 방법을 제시하고자 하였다. 방법: 2002년 4월부터 2002년 12월까지 내원한 5-l5세 사이의 환자로서 1) 일차성 단일성 야뇨증, 2) 주 2회 이상의 야뇨증, 3) 5세 이상의 연령, 4) 비뇨기과적 이상이 없고, 5) 정신적 또는 신경학적인 증상이 없으며, 6) 내분비 질환이 없고, 7) 최근 2개월 동안 야뇨증 약물치료를 받지 않은 환아로서, 8) 부모의 동의를 받은 경우를 대상으로 하였으며 조건을 만족하는 환자들을 무작위로 선택하여 imipramine 단독투여군, desmopressin 단독투여군과 imipramine과 desmopressin 복합투여군의 3군으로 나누어 야뇨횟수, 부작용과 약물 중단 후 1개월 후 야뇨증 빈도를 확인하였다. 결과: 대상 환아들은 남, 녀 각각 78명과 90명이며, 5-10세가 119명이었고 11-16세는 49명이었다. 치료 시작 4주 이후에서부터 모든 군에서 유의하게 야뇨 횟수가 감소하였다. 치료 종료 시의 imipramine 단독투여군, desmopressin 단독투여군과 imipramine과 desmopressin 복합투여군의 치료율은 각각 68.6%, 74.4%와 86.1%로서 imipramine와 desmopressin 복합투여군의 치료율이 가장 높았으나 통계학적인 차이는 없었다. 치료 종료 후 4주의 야뇨 빈도는 imipramine 단독투여군은 주당 1.9회, desmopressin 단독투여군은 1.3회이고 imipramine와 desmopressin 복합투여군은 1.0회로 세군 사이에는 유의한 차이가 없었다. 약물에 의한 부작용은 imipramine 단독투여군은 20명, desmopressin 단독투여군은 12명, imipramine와 desmopressin 복합투여군13명에서 총 45례에서 나타났는데 이중 imipramine 투여로 인한 식욕 감퇴가 가장 많았다. 결론: 일차성 단일 증상성 야뇨증 치료를 위한 imipramine 단독용법, desmopressin 단독요법, imipramine과 desmopressin 복합요법의 치료효과와 단기간 동안 관찰한 재발 빈도에서는 의미있는 차이는 없어서, 두 약제의 복합요법이 desmopressin 단독 요법에 비해 치료효과, 재발정도와 부작용 빈도에서 차이가 없어 치료 효율성의 우월성을 발견하지 못하였다. 다만 약물 부작용 발생은 imipramine 단독요법이 다른 치료 방법에 비해 발생 빈도가 유의하게 높은 것으로 나타나서 imipramine 단독요법을 할 때에는 부작용 발생유무를 유의해서 관찰하여야 할 것으로 생각된다.

Ulcerative colitis (UC) is characterized by a life-long chronic course with remissions and exacerbations. Use of biological therapies may reduce or delay the surgical procedures in patients with UC. The aim of this study was to determine the impact of infliximab (IFX) use on the rate of remission, surgical interventions, and the effect on quality of life in patients with moderate to severe UC. Literature was searched for studies that investigated the efficacy of IFX on the rate of remission, colectomy and quality of life (QoL) between January 1990 and June 2012 at MEDLINE, January 1988 and June 2012 at EMbase and others. Eleven trials were included in the meta-analysis; divided into placebo controlled 8 trials and intravenous corticosteroid controlled group 3 trials. In comparison to placebo control groups, patients who received IFX had an odds ratio (OR) of 3.712 (95% CI: 2.714, 5.079) for the short-term clinical remission, and 3.053 (95% CI: 2.044, 4.559) for the rate of long-term remission. In colectomy rate and quality of life (QoL), odds ratio were 0.566(95% CI: 0.387, 0.827) and 0.658 (0.505, 0.811) respectively. Any adverse reactions including infections, infusion reaction, rash and arthralgia were equivalent in both groups. Compared with intravenous corticosteroid controlled group, patients who received IFX had lower remission rate with short-term odds ratio 0.227 (95% CI: 0.033, 1.556) and long-term odds ratio 1.054 (95% CI: 0.317, 3.502) respectively. However, statistical significance was not showed with both two analyses. The higher adverse drug reaction (ADR) rates were occurred in the corticosteroid controlled groups. 73.3% of patients treated corticosteroid reported Cushing-like syndrome with moon face. In conclusion, IFX does increase remission rate and decrease the rate of colectomy in patients with UC without elevating any adverse reactions significantly. IFX also improves QoL in moderate to severe UC patients. It would not exceed the efficacy of intravenous corticosteroid, whereas intravenous corticosteroid also reported high rate of adverse reactions.

Background: Small-molecule tyrosine kinase inhibitors (TKIs) have had major impacts on anticancer therapy by targeting the catalytic activities of dysregulated tyrosine kinases. TKIs have not presented traditional toxicities; however, some serious adverse effects, including hepatotoxicity, have been documented in clinical trials and post-marketing surveillance. Although TKI-induced hepatotoxicity can cause severe clinical complications in patients, the underlying mechanism is still unclear. Methods: Studies on TKI-induced hepatotoxicity were identified by Pubmed search, and relevant articles were reviewed. Results: Immunoallergic reaction, cytochrome P (CYP) 450 polymorphisms, and formation of reactive metabolites are under consideration as mechanisms of TKI-induced hepatotoxicity. Host protein-drug metabolite conjugates are recognized as antigens by class II major histocompatibility complexes and are believed to cause liver injuries. Polymorphisms in CYP, which influences TKI metabolism, can slow TKI metabolism and may induce development of hepatotoxicity. The formation of reactive metabolites during drug metabolism can induce hepatotoxicity by directly causing cytotoxicity, leading to cell dysfunction, and indirect toxicity by mediating secondary immune reactions. Concurrent use of various medications with TKI can also cause hepatotoxicity by affecting drug transporter or enzyme activities. Conclusion: Periodic monitoring of patients taking TKIs and risk/benefit reassessments though post marketing surveillance are necessary to prevent hepatotoxicity.

Background: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are immune-complex-mediated hypersensitivity reactions that predominantly involve skin and mucous membranes. Despite the low incidence, both are considered medical emergencies as the mortality rate has been estimated at 30-50%. Although as many as half of cases are idiopathic, several drugs have been implicated as main cause of SJS/TEN. This review therefore aimed to identify drugs that were potentially associated with SJS/TEN and compare the relative risk of the medications. Method: A comprehensive search was performed using MEDLINE, EMBASE and 5 Korean databases. We defined study drugs as non-steroidal anti-inflammatory drugs (NSAIDs), antibiotics, antiepileptics, and allopurinol. Only epidemiologic studies investigating associations between the above drugs and drug-induced SJS/TEN were included. Two reviewers independently selected and evaluated candidate papers and extracted odds ratios or incidence rates. Meta-analysis was performed only for drugs that were reported from 4 or more studies. Results: We found 8 case-control studies, 3 cohort studies and 1 RCT. The ranges of adjusted ORs were 0.6-34.0 for NSAIDs, 1.6-302.0 for antiepileptics, 0.3-10.0 for antibiotics and 1.0-187.0 for allopurinol. The drug with the highest incidence of SJS/TEN was carbamazepine (40 persons/1,000 DDD). Conclusion: Finally, the risk was highest in first 8 weeks after onset of treatment in all drugs.

현대 과학의 경험과 성과가 반영된 의약품의 사용으로 인류에게 질병의 치료와 건강 상태의 개선이라는 혜택이 주어지고 있다. 그러나 의약품은 질병의 치료라는 혜택 이외에도 본질적으로 피할 수 없는 부작용도 내포한다. 각국은 부작용으로 인한 피해의 최소화를 위해 시장진입 규제나 시판후조사 등의 조치를 취하고 있으나, 부작용의 발생은 피할 수 없다. 부작용으로 인한 손해의 발생이 불가항력이라도 그 점이 사전에 알려진 것이었다면, 의약품의 종류와 사용 형태에 따라서 처방한 의사나 복약지도를 담당하는 약사 등이 손해를 배상해야 한다. 의약품에 결함이 있어 손해가 발생하는 경우도 있는데, 손해 배상의 일반원칙을 그대로 적용해서는 결함으로 인한 부작용 피해자가 손해를 배상받기 쉽지 않다. 우리나라를 비롯한 여러 나라가 제조물 책임법을 통하여 피해자의 보호를 도모하고 있으며, 의약품도 제조물에 포섭되기 때문에 제조물 책임법을 통한 손해배상을 문의할 수 있는데, 이 때 주로 설계상의 결함이나 표시상의 결함이 문제될 수 있다. 제조물 책임법이 제정·시행되기 이전에도 의약품의 부작용으로 인한 손해는 발생하여왔다. 이러한 경우를 위해서 판례는 제조물 책임법과 유사한 법리를 발전시켜 왔고, 의약품 결함은 혈액제제와 관련하여 판례가 형성되어 왔다. 제조물 책임법 시행 이전에 제조된 의약품으로 인한 손해는 향후에도 발생할 수 있기에 판례 법리는 중요한 검토의 대상이다.

Many drugs are primarily metabolized by the cytochrome P450s (CYPs). Drug metabolites would be important allergens for adverse drug reactions such as drug eruptions. Skin tests with a suspected drug have conducted to identify causative drugs of drug eruptions, with vehicles such as white petrolatum, DMSO, ethanol. This study will compare the expression of rat CYP isozyme mRNAs between the skin and the liver, with examining an effect of the vehicles on the cutaneous CYPs using semi-quantitative RT-PCR. Thirty-two Sprague-Dawley rats between the ages of six and eight weeks were divided as four groups. One group was used to compare the constitutive mRNA expression between skin and liver, while the others were to examine the effects of three vehicles. The ratios of expression of CYP1A2, CYP2B1/2, CYP2E1, CYP3A1, and CYP4A1 were significantly higher in the liver than the skin. However, CYP1A1 and CYP2C11 were higher in the skin than liver. The effects of vehicles were quite different; white petrolatum significantly induced CYP1A1 (p=0.012) and CYP2C11 mRNAs, while ethanol inhibited CY P1A1 and CYP2B1/2. DMSO did not make any changes. The results suggest that rat skin can participate in drug metabolism with their own CYP isozymes. The effects of vehicles on the cutaneous CYP expression should not be ignored and may be applied for determination of an appropriate vehicle for certain drug(s).

Tapentadol is a novel oral analgesic with a dual mode of action as an agonist of the ${\mu}$-opioid receptor (MOR), and as a norepinephrine reuptake inhibitor (NRI) all in a single molecule. Immediate release (IR) tapentadol shows its analgesic effect quickly, at around 30 minutes. Its MOR agonistic action produces acute nociceptive pain relief; its role as an NRI brings about chronic neuropathic pain relief. Absorption is rapid, with a mean maximal serum concentration at 1.25-1.5 h after oral intake. It is present primarily in the form of conjugated metabolites after glucuronidation, and excretes rapidly and completely via the kidneys. The most common adverse reactions are nausea, dizziness, vomiting, and somnolence. Constipation is more common in use of the ER formulation. Precautions against concomitant use of central nervous system depressants, including sedatives, hypnotics, tranquilizers, general anesthetics, phenothiazines, other opioids, and alcohol, or use of tapentadol within 14 days of the cessation of monoamine oxidase inhibitors, are advised. The safety and efficacy have not been established for use during pregnancy, labor, and delivery, or for nursing mothers, pediatric patients less than 18 years of age, and cases of severe renal impairment and severe hepatic impairment. The major concerns for tapentadol are abuse, addiction, seeking behavior, withdrawal, and physical dependence. The presumed problem for use of tapentadol is to control the ratio of MOR agonist and NRI. In conclusion, tapentadol produces both nociceptive and neuropathic pain relief, but with worries about abuse and dependence.
