The etiology of rheumatic arthritis (RA) is associated with a number of genetic and environmental factors, but is not definitively elucidated. Recently, more attention has been paid to the possibility of microbial etiology in the pathogenesis of RA, because many different infectious agents have been reported to precede the onset or exacerbation of RA. Adenovirus (ADV) may be one cause of persistent or recurrent inflammatory arthritis. Varicella zoster virus (VZV) arthritis is detected frequently in RA patients treated with low dose methotrexate. The demonstration of simultaneous presence of both viral agents of specific viral nucleic acid in synovial fluids from synovitis patients would provide more direct evidence for arthritis etiological relationship, but there are no confirmed results. Therefore, we studied the ability of adenovirus and VZV to establish coinfection and persistent infection in synovial fluid from synovitis patients. The presence of viral agents in the synovial fluid demonstrated by isolation of cell culture, enzyme immunoassay and nested-PCR. The synovial fluids were also investgated for the presence of viral nucleic acid by nested-PCR using specific primer. ADV produced 220 bp and VZV produced 447 bp by each nested-PCR with specific primers. We detected 4/6 cases (66.7%) with persistent infection of ADV and 5/6 cases (83.3%) of VZV with 13 synovial fluids (between 7 to 52 day intervals) from synovitis patients by monoclonal ErA and nested-PCR. 21/28 cases (75%) with coinfection of adenovirus and VZV with synovial fluids from synovitis patients by nested-PCR. ADV and VZV coinfection and persistent infection of synovial fluids may provide a chronic antigenic stimuli to the immune system therefore provoking a continuing inflammatory response and caused the possibility of synovitis and arthritis.

목적: 본 연구는 단일 기관에서 수두-대상포진 바이러스 감염으로 입원한 소아 환자의 임상 경과를 알아보고자 하였다. 방법: 2009년부터 2012년까지 서울대학교 어린이병원에서 피부 병변의 수포액으로 시행한 수두-대상포진 바이러스 배양검사와 중합효소 연쇄반응검사로 수두-대상포진 바이러스 감염증이 확진된 40명의 입원환자를 대상으로 하였다. 환자들의 의무기록을 통하여 진단 시 연령 및 성별, 수두 백신 시행유무, 임상증상 및 경과, 기저질환, 치료와 합병증에 대하여 분석하였다. 결과: 대상자 중 수두 환자는 16명, 대상포진 환자는 24명이었고, 연령 중앙값은 10.5세로 생후 16일부터 19세까지 분포하였다. 기저질환이 동반된 환자는 35명(87.5%)이었고, 24명의 대상포진 환자 중 과거에 수두를 앓았던 경우가 11례에서 있었고, 재발한 대상포진은 1례에서 있었다. 20명(50%)은 이전에 수두 백신의 접종력이 있었고, 이 중 19명은 면역저하환자였다. 대부분의 환자(95%)는 정맥용 또는 경구용 항바이러스제로 치료받았고, 정맥용 항바이러스제 투여 후 치료 실패는 관찰되지 않았다. 면역저하환자에서 발열의 기간은 평균 4.4일(1-10일)로 정상 면역력을 가진 환자와 비교하였을 때 유의한 차이는 없었으나, 항바이러스제의 투여기간은 평균 12일(7-23일)로 유의하게 길었다(P=0.014). 두 명(5.0%)의 환자에서 Streptococcus pyogenes와 Klebsiella oxytoca에 의한 이차 세균 감염이 확인되었으며, 1명(2.5%)에서 폐렴이, 11명(27.5%)에서 대상포진후 신경통이 합병되었다. 결론: 수두-대상포진 바이러스 감염은 면역저하 소아에서 발생할 시에 장기간의 항바이러스제 치료가 필요하므로 이 같은 환자들을 적극적으로 치료하고, 면밀하게 관찰하는 것이 필요하다.

Zoster sine herpete (ZSH) is a varicella zoster virus (VZV) reactivation without a zoster that is difficult to diagnose early after onset. This study examined 12 patients who presented with intercostal neuralgia, had no history of trauma, cutaneous eruption and no scar of a herpes zoster on the lesion. Two patients had a vertebral compression fracture. Two patients had a history of a zoster in the other site. No other suspicious findings were observed. Ten of the twelve patients were checked for the IgG and IgM varicellar zoster virus antibody. All the patients tested positive to the Ig G antibody test and only one patient tested positive to the IgM antibody test. One patient was confirmed to have ZSH and the other patients were suspected of having ZSH. All the patients were treated for postherpetic neuralgia, resulting in a significant decrease in the intercostal neuralgia.

;The Varicella zoster virus can cause two infectious diseases. The primary infection of this virus leads to Chicken pox and it goes into a latent period until it reveals itself again. When secondarily shown. it is called Herpes Zoster. Herpes Zoster can usually be seen between T-3 and L-2 of immunodepressant patients but in 13%. it is seen in the trigeminal nerve branch. During the predrominal stage. burning sensation, itching. and sharp pain can be experienced unilaterally where the nerve branch is distributed. Patients can also express tooth pain in this stage. After 2-4 days the acute stage begins with its characteristic unilateral macule showing vesicle formation. In this stage fever and fatigue can be experienced. Continuous pain even after the acute stage is called postherpetic neuralgia; deep pain and burning sensation can be expressed by the patient. The sequelae of this disease consists of rare osteomyelitis. necrosis of the jaws. or loss of teeth.teeth.

목 적 : 수두에 대한 개체 면역력을 평가하는데 있어서 약독화 수두백신을 불활성화 시킨 후 희석시켜 만든 용액을 이용한 피부시험이 유용한지를 알아보고자 하였다. 방 법 : 2005년도 7월에서 8월까지 한림대의료원 강동성심병원 의료진 19명과 입원한 소아 22명을 포함한 총 41명(남자 22명, 여자 19명, 만 1-32세)을 대상으로 하였다. 수두 감염의 과거력, 수두 예방접종 여부에 대한 사항은 설문지를 통해 이루어졌고 피부시험을 위한 용액은 Oka 균주의 약독화 수두백신을 상온에 10일간 방치하여 불활성화 시킨 후, 이를 다시 생리식염수로 50배 희석하여 사용하였다. 이 용액을 우측 상완 전박부에 피내 주사하였고 대조액으로 반대편 상완 전박부에 생리식염수액을 피내 주사하였다. 48시간 이후 경결의 직경 5 mm 이상일 때 양성으로 판독하였다. 또한 효소면역분석법을 이용하여 혈청 VZV 특이 IgG 항체가를 측정하여 피부시험 결과와 비교 분석하였다. 결 과 : 효소면역분석법을 이용한 항체 검사에 대한 성인에서의 수두 피부시험의 민감도는 94.7%이고 양성 예측도는 100%였다. 동일한 판정 기준을 소아에 적용하였을 때 양성 예측도와 특이도는 100%로 높았으나 민감도와 음성 예측도는 각각 50%, 30.7%로 낮았다. 소아에서의 VZV 피부반응도는 성인에 비해 낮았다. 결 론 : 약독화 수두백신을 불활성화, 희석시켜 만든 용액을 이용한 피부시험은 수두에 대한 면역력을 예측하는데 있어, 간편하고 안전한 저가의 유용한 검사이다. 그러나 피부시험에서 양성판정기준을 결정할 때 조사목적, 대상연령 등을 고려하여 신중히 판단하여야 할 것이며, 이에 대해서는 향후 더 많은 대상에서 추가 연구가 이루어져야 할 것으로 사료된다.

Background: Varicella is the most common infectious disease reported despite the high vaccination rate. Interventions that target humans are particularly effective for varicella because humans are its only natural host. On the other hand, the existing national varicella surveillance systems lack the information to identify an outbreak. Therefore, a new index to assess varicella outbreaks was developed. Methods: The residential addresses of 2,718 varicella cases reported in Daegu in 2016 were converted to geographic coordinates and the distances between new varicella case and previous cases within 21 days were calculated from the date analyzed. Two cases were considered to be adjacent if the distance between them was less than 1 km. Finally, a proximity index was introduced by dividing the number of adjacent cases by the number of new cases on the date analyzed. Results: First, time-series charts and scatter plots were used to verify that the proximity index reflected the spatial closeness of the different varicella cases. The proximity index is helpful in identifying outbreaks from a list of single varicella cases. In addition, in this study, a new epidemic characteristic of varicella based on the proximity index was shown. Conclusion: The proximity index introduced in this study can be used to determine the likelihood of an outbreak from a single case of varicella, and it can be embedded in a web-based national varicella surveillance system that is currently in operation.

Herpes zoster as a result of reactivated varicella-zoster virus is characterized by vesicular eruptions on skin and painful neuralgia in the dermatome distribution. Pain during an acute phase of herpes zoster has been associated with a higher risk of developing postherpetic neuralgia. The current therapies for herpes zoster including analgesics and sympathetic nerve block as well as antiviral agents are important to alleviate pain and prevent postherpetic neuralgia. However, in some cases, the pain does not respond well to these treatments. We had a case in which a patient with herpes zoster did not respond to conventional therapy so we attempted to administer intravenous infusion of vitamin C which resulted in an immediate reduction in the pain.

Oka strain VR-795 (Varicella Zoster Virus, VZV) of American Type Culture Collection (ATCC) has been used for chickenpox vaccine production. In order to use this strain for vaccine production, the strain must be identified and its stability must be confirmed. The identification of the Oka strain has been confirmed using Restriction Fragment Length Polymorphism (RFLP) and DNA sequence analysis of glycoprotein-II (gp-II). The amino acid sequences of Oka deduced from the DNA sequence of gp-II have changed at three amino acids against Ellen and at one amino acid against Webster. To prove the stability of the Oka strain during the passage, RFLP and DNA sequence analyses were also used with 11, 15 and 23 times of virus passage. We found that the Oka strain was stable at passages of up to 23 times, based on the RFLP and DNA sequence analyses. The confirmed Oka strain was renamed as BR-Oka for the purposes of chickenpox vaccine production.
