쇼크 갑상샘(shock thyroid)은 CT 저혈압 복합체(CT hypotension complex)의 드문 발현 중 하나이며, 쇼크 상황에서 CT상 갑상샘과 갑상샘 주위에 부종이 관찰될 때 진단 가능하다. 쇼크 갑상샘은 비보상성 쇼크를 시사하는 유용한 CT 징후일 수 있다. 이 상태는 가역적이며 적절한 치료를 통해 빠르게 회복될 수 있다. 저자들은 쇼크 갑상선과 일치하는 CT 소견을 보인 패혈성 쇼크 상태의 84세 여자 환자의 증례를 보고한다. 이와 더불어, 문헌에 보고된 임상 및 영상 소견을 함께 고찰하고자 한다. 본 증례는 쇼크 갑상선이 임박한 혈류역학적 불안정성의 초기 지표가 될 수 있으며, 중요한 예후 및 치료적 함의가 될 수 있음을 강조한다.

Background and Objectives: The prognostic implications of septic cardiomyopathy have not been clearly demonstrated. We evaluated serial changes in left ventricular (LV) and right ventricular (RV) function in patients with septic shock and their prognostic value on 7-day and in-hospital mortality. Methods: Transthoracic echocardiography was performed within 48 hours of the diagnosis of septic shock and 7 days after the initial evaluation. In addition to traditional echocardiographic parameters, LV and RV function was evaluated using global longitudinal strain (GLS), and tricuspid annular plane systolic excursion (TAPSE). Results: A total of 162 patients (men, 83, 51.5%; 70.7±13.4 years; Acute Physiology and Chronic Health Evaluation [APACHE] II, 30.6±9.2) were enrolled. Initial GLS and TAPSE were -14.9±5.2% and 16.9±5.5 mm, and improved in the follow-up evaluation (GLS, -17.6±4.9%; TAPSE, 19.2±5.4 mm). Seven-day and in-hospital mortality were 24 (14.9%) and 64 (39.8%). Seven-day mortality was significantly associated with initial GLS >-16% (odds ratio [OR], 14.066, 95% confidence interval [CI], 1.178-167.969, p=0.037) and APACHE II score (OR, 1.196, 95% CI, 1.047-1.365, p=0.008). The in-hospital mortality of 7-day survivors was associated with follow-up TAPSE <16 mm (OR, 10.109, 95% CI, 1.640-62.322, p=0.013) and Sequential Organ Failure Assessment score (OR, 1.340, 95% CI, 1.078-1.667, p=0.008). GLS was not associated with in-hospital mortality of 7-day survivors. Conclusions: Fluctuation of both ventricular function was common in septic shock. Seven-day mortality of patients with septic shock was related to GLS, whereas in-hospital mortality of 7-day survivors was related to TAPSE, not to GLS.

Purpose: To assess whether the Modified Early Warning Score (MEWS) predicts the need for intensive care unit (ICU) transfer for patients with severe sepsis or septic shock admitted to general wards. Methods: A retrospective chart review of 100 general ward patients with severe sepsis or septic shock was implemented. Clinical information and MEWS according to point of time between ICU group and general ward group were reviewed. Data were analyzed using multivariate logistic regression and the area under the receiver operating characteristic curves with SPSS/WIN 18.0 program. Results: Thirty-eight ICU patients and sixty-two general ward patients were included. In multivariate logistic regression, MEWS (odds ratio [OR] 2.02, 95% confidence interval [CI] 1.43-2.85), lactic acid (OR 1.83, 95% CI 1.22-2.73) and diastolic blood pressure (OR 0.89, 95% CI 0.80-1.00) were predictive of ICU transfer. The sensitivity and the specificity of MEWS used with cut-off value of six were 89.5% and 67.7% for ICU transfer. Conclusion: MEWS is an effective predictor of ICU transfer. A clinical algorithm could be created to respond to high MEWS and intervene with appropriate changes in clinical management.

연구배경 : 패혈성 쇼크에서는 혈압이 저하됨에도 불구하고 혈중 AVP의 농도가 낮은데, 그 이유는 미생물에서 유리된 독소에 따른 염증반응을 매개로 증가한 산화질소(NO)가 혈관을 확장시켜 이차적으로 AVP의 고갈을 유발하기 때문인 것으로 알려져 있다. 한편 패혈성 쇼크의 치료를 위해 사용하는 노르에피네프린과 카테콜아민계 승압제는 다량 사용시 내부 장기의 혈류감소를 유발할 수 있다. 이에 본 저자들은 페혈성 쇼크 환자에게 AVP를 정주함으로써 승압제의 감량과 신기능의 향상이 일어나는지 알아보았다. 방 법 : 혈압의 유지를 위해 다량의 승압제를 투여중인 여덟 명의 패혈성 쇼크 환자들을 대상으로 AVP를 4시간 동안 정주하였다. 투여전, 투여중 및 투여 종료 4시간 경과후 시점을 기준으로 평균 동맥압 및 노르에피네프린의 투여속도, 시간당 소변량을 측정하였다. 결 과 : AVP의 정주 결과, 세 측정 시점 사이에서 평균 동맥압의 유의한 변화는 일어나지 않은 채로(p=0.197) 노르에피네프린의 투여속도(${\mu}g/min$)을 유의하게 감소시킬 수 있었다(p=0.001). 그러나, 시간당 소변량은 측정 시점 사이에 차이가 없었다(p=0.093). 결 론 : 패혈성 쇼크 환자에게 AVP를 정주한 결과, 카테콜아민계 승압제의 투여속도를 유의하게 줄일 수 있었다. 그러나 단시간 AVP 정주에 따른 시간당 소변량은 유의한 변화를 나타내지 않아 향후 AVP 투여가 주요 장기 및 생존율에 미치는 영향에 대한 추가 연구가 필요할 것이다.

Kunitz-type soybean trypsin inhibitor (SBTI) and chondroitin sulfate (A, and C type) were conjugated using sodium periodate method. And the physicochemical, pharmacokinetic properties and immunogenecity of the conjugates (Chon-A-SBTI or Chon-C-SBTI) were characterized. We expected the conjugation using chondroitin sulfate to reduce the immunogenecity and to improve the pharmacological effect. As the results, the mean molecular weight of the conjugate highly increased. After I.V. injection of the radiolabeled conjugates or native SBTI into mice, it was found that native SBTI showed rapid elimination from plasma, whereas Chon-A-SBTI and Chon-C-SBTI were slowly eliminated. Organ distribution of the two agents at 30 min after I.V. injection was different : Chon-A-SBTI or Chon-C-SBTI accumulated to a large extent in the liver (13% in Chon-A-SBTI and 16% in Chon-C-SBTI), whereas native SBTI was taken up more rapidly by the kidney (107% dose/g of tissue) and excreated into the urine (26%). In addition we evaluated the therapeutic value of the conjugates by using the sublethal septic shock model caused by pseudomonal elastase and tested the immunogenecity by passive cutaneous anaphylaxis shock (PCA). The conjugates were more effective than native SBTI against pseudomonal elastase induced septic shock in guinea pig. In case of the conjugates, the pharmacological and therapeutic effect lasted over 3 hours long. In immunogenecity test, both of the conjugates showed the reduction of their immunogenecity, especially Chon-A-SBTI looked most effective.

Three kinds of serine protease inhibitors, members of the Bowman-Birk trypsin inhibitor, were purified from Dolichos lablab seeds and named Dolichos protease inhibitor 1, 2 and 3 (DI-1, DI-2 and DI-3), respectively. Each inhibitor showed a single band with gel mobility at around 15.9, 12.1 and 14.6 kDa on 20% SDS-PAGE under reducing conditions. To characterize inhibitory specificity, the inhibition constant (Ki) for these inhibitors was measured against several known serine proteases. All three Dolichos protease inhibitors (DI-1, DI-2 and DI-3) inhibited the activity of trypsin and plasmin, but had no effect on thrombin and kallikrein (either for human plasma kallikrein or for porcine pancreas kallikrein). DI-1 inhibited chymotrypsin most effectively (Ki = $3.6{\times}10^{-9}\;M$), while DI-2 displayed inhibitory activity for porcine pancreatic elastase (Ki = $6.2{\times}10^{-8}\;M$). Pre-treatment of the 33 mg/kg of DI-mixture (active fractions from $C_{18}$ open column chromatography that included DI-1, DI-2 and DI-3) inhibited the induction of pseudomonal elastase-induced septic hypotension and prevented an increase in bradykinin generation in pseudomonal elastase-treated guinea pig plasma. Also, the increase of kallikrein activity, by injection of pseudomonal elastase, was inhibited by the pretreatment of the DI-mixture in a guinea pig. Since the DI-mixture had no inhibitory effect on kallikrein activity when Z-Phe-Arg-MCA was used as a substrate in vitro, its inhibitory activity in the pseudomonal elastase-induced septic hypotension model might not be due to a direct inhibition of plasma kallikrein in the activation cascade of the Hageman factor and prekallikrein system. These results suggest that the Dolichos DI-mixture might be used as an inhibitor in pathogenic bacterial protease-induced septic shock.

A 60-year-old woman with a history of diabetes mellitus and chronic renal failure was admitted to the hospital with severe pain in the upper lip, which began 4 days prior to admission, accompanied by a bullous lesion and suspected cellulitis in the upper lip. Immediately after admission, as the patient's general condition worsened, tests revealed a non-ST elevated myocardial infarction, septic embolism of the lung, as well as septic shock. Her upper lip suddenly presented a gangrenous and necrotic change, which the tissue and blood culture confirmed to be a Klebsiella pneumoniae infection. After a quick response, the patient's general condition improved. Subsequently, serial debridement was performed to effectively clear away the purulent discharge. While under general anesthesia, the process confirmed full-layer necrosis of the upper lip including the orbicularis oris muscle. Almost half of the entire upper lip sustained a full-layer skin and soft tissue defect, with scar contracture. Six months later, to correct the drooling and lip sealing following the defects, a scar release and an Abbe flap coverage were performed considering both functional and aesthetic aspects. The follow-up revealed a favorable corrective result of the upper lip drooling, and the patient was satisfied from a functional perspective.

Severe sepsis or septic shock is characterized by an excessive inflammatory response to infectious pathogens. Acute respiratory distress syndrome (ARDS) is a devastating complication of severe sepsis, from which patients have high mortality. Advances in treatment modalities including lung protective ventilation, prone positioning, use of neuromuscular blockade, and extracorporeal membrane oxygenation, have improved the outcome over recent decades, nevertheless, the mortality rate still remains high. Timely treatment of underlying sepsis and early identification of patients at risk of ARDS can help to decrease its development. In addition, further studies are needed regarding pathogenesis and novel therapies in order to show promising future treatments of sepsis-induced ARDS.

Severe sepsis and septic shock is a life-threatening disease. It is combined with multi-organ failure. In the past decade, early goal directed therapy has been proposed as an effective treatment strategy for better outcome. Recent epidemiologic studies showed that the outcome of sepsis has been improved with the introduction of early goal directed therapy. However, it is unclear which elements of early goal directed therapy contributed to the better outcome. Recent prospective and randomized trials suggested that some elements of early goal directed therapy did not have any effect on the outcome benefit. In this paper, recent articles about early goal directed therapy will be reviewed and the effectiveness of individual elements of early goal directed therapy will be discussed.

Symmetrical Digital Gangrene (SDG) is characterized by the sudden onset of peripheral, symmetrical gangrene in the absence of any major vascular occlusive disease. Catecholamine inotropes are frequently used for the treatment of septic shock combined with an unstable hemodynamic state, and their usage can rarely induce SDG. There is no standard treatment for the SDG. Early recognition and prompt management of sepsis and expeditious process of weaning off of the inotropes are necessary to prevent progression of SDG. To the best of our knowledge, this is the first report in Korea regarding the treatment of SDG induced by catecholamine inotropes.
