Anti-HSV type 2 Monoclonal antibody

This article presents a study on women living in Attica, Greece (an area of 4.5 million inhabitants) who visited the outpatient clinics of two specialized hospitals for a follow-up for cervical intraepithelial neoplasia (CIN 3). A random sample of 170 women with CIN 3 and a control group of 195 women coming from the general population were interviewed. A semi-structured designed questionnaire was used as an instrument for data collection. The aim of the study was to search for a possible correlation between CIN 3 and a past history of herpes genitalis (HSV2) of the women and/or their partners. According to the results, CIN 3 is more frequent among women between 26 and 40 years of age. The majority of the patients (70.3 %) reported a past history of HSV2, but only 10.9% of the subjects in the control group had the same medical history (p=0.000). Sixteen percent of the patients and only 5.3% of the subjects in the control group reported infection of their sexual partners with HSV2. 75 patients (44.6%) stated that they did not know if their sexual partners had a past history of HSV2 while only 27 women (13.3%) in the control group reported the same (p=0.000). Patients reported more sexual partners than women in the control group.

Infectious agents play a critical role in MALT lymphoma development. Studies from Italy showed Chlamydia psittaci infection in 87% of ocular adnexal MALT lymphomas and complete or partial regression of the lymphoma after C psittaci eradication in four of nine cases. However, C. psittaci was not demonstrated in ocular adnexal MALT lymphomas from the USA. This study was thus designed to investigate further the role of C psittaci, and other infectious agents commonly associated with chronic eye disease, in the development of ocular adnexal MALT lymphoma. The presence of C psittaci, C trachomatis, C pneumoniae, herpes simplex virus 1 and 2 (HSV1, HSV2), and adenovirus 8 and 19 (ADV8, ADV19) was assessed separately by polymerase chain reaction in 142 ocular adnexal MALT lymphomas, 53 non-marginal zone lymphomas, and 51 ocular adnexal biopsies without a lymphoproliferative disorder (LPD), from six geographical regions. C psittaci was detected at similar low frequencies in non-LPD and non-marginal zone lymphoma groups from different geographical regions (0-14%). Overall, the prevalence of C psittaci was significantly higher in MALT lymphomas (22%) than in non-LPD (10%, p = 0.042) and non-marginal zone lymphoma cases (9%, p = 0.033). However, the prevalence of C. psittaci infection in MALT lymphoma showed marked variation among the six geographical regions examined, being most frequent in Germany (47%), followed by the East Coast of the USA (35%) and the Netherlands (29%), but relatively low in Italy (13%), the UK (12%), and Southern China (11%). No significant differences in the detection of C. pneumoniae, C trachomatis, HSV1, HSV2, ADV8, and ADV19 were found between lymphomas and controls from different geographical regions. In conclusion, our results show that C psittaci, but not C. pneumoniae, C. trachomatis, HSV1, HSV2, ADV8 or ADV19, is associated with ocular adnexal MALT lymphoma and that this association is variable in different geographical areas.
