Obstet Gynecol 2016; 128: 52).<\/p>\n<p>Details:<\/p>\n<ul>\n<li>68 providers, 4 of whom did regular pap screening,\u00a0with\u00a01827 HIV-positive women seen in 2015. Rate of pap testing was 47%<\/li>\n<li>238 women\u00a0were\u00a0seen between 2000-2015 with a\u00a0history of HIV, previous hysterectomy, and no previous abnormal Pap test results<\/li>\n<li>Median follow-up time for the Pap test was 16 years.<\/li>\n<li>Results:\n<ul>\n<li>164 (69%) had normal Pap test results<\/li>\n<li>12 (5%) had results showing atypical cells of undermined significance and human papillomavirus-positive<\/li>\n<li>55 (23.1%) had results showing low-grade squamous intraepithelial lesion<\/li>\n<li>7\u00a0(2.9%) had results showing high-grade squamous intraepithelial lesion<\/li>\n<li>Of those who underwent biopsy for abnormal pap tests:\n<ul>\n<li>15 (28%) had normal results<\/li>\n<li>23 (43%) had VAIN 1<\/li>\n<li>9 (16%) had VAIN 2<\/li>\n<li>7 (13%) had VAIN 3<\/li>\n<li>No patients had invasive vaginal cancer.<\/li>\n<\/ul>\n<\/li>\n<li>No demographic risk factor was associated with the\u00a0abnormal Pap test results after hysterectomy (race, smoking history, alcohol history, illegal drug use). Also no association with a\u00a0specific indication for the hysterectomy (fibroids vs pelvic pain vs bleeding). The story was mixed on\u00a0HIV-related risk factor (though overall there was not much difference in CD4\u00a0or viral load between those with normal vs abnormal paps,\u00a0within 6 months of the pap abnormalities there was\u00a0a\u00a0significant\u00a0deterioration: median CD4 was 573 vs 364, and viral load was 248 vs 400, all values with p&lt;0.001)<\/li>\n<li>Older patients and higher viral load significantly increased the risk of development of an abnormal Pap test result. For example, the patients with viral load values greater than 400 had approximately two times the risk of developing an abnormal Pap test result than those lower than 400; the adjusted hazard ratio of\u00a02.1 (95% CI 1.2\u20133.5).

N Engl J Med 1996; 335: 1559, which noted that of 9610 vaginal smears,\u00a0atypical squamous cells of undetermined significance (ASCUS)\u00a0occurred in\u00a052 (0.5%); low-grade squamous intraepithelial lesion in\u00a044 (0.5%); high-grade squamous intraepithelial lesion in\u00a06 (0.1%); and squamous-cell carcinoma in\u00a02 (0.02%). In 5\u00a0women, biopsies revealed vaginal intraepithelial neoplasia type I or II; there were no biopsy-proved cases of vaginal cancer. The probability of an abnormal Pap\u00a0smear in this group of women was 1.1 percent, and the positive predictive value of the Pap\u00a0test for detecting vaginal cancer was 0.Mean time to get potentially significant\u00a0intraepithelial lesions was 19 yrs. Because of the age of this study, there was no\u00a0information about HIV or HPV status.<\/li>\n<\/ul>\n<\/li>\n<li>There are very limited data and no clear recommendations on pap testing in\u00a0HIV-positive\u00a0women having a hysterectomy for benign reasons.<\/li>\n<\/ul>\n<\/li>\n<li>There are several unanswered questions (which really should be studied).\n<ul>\n<li>This Texas study\u00a0was a retrospective analysis with limited data collected and there are\u00a0no\u00a0data I&#8217;ve seen\u00a0on the\u00a0effect of interventions on changing actual\u00a0clinical\u00a0outcomes\u00a0in abnormalities picked up\u00a0by routine screening<\/li>\n<li>We know that HPV infection tends to persist in HIV-positive men and women, with attendant increased risk of anal and cervical cancers. It would be great if there were prospective data looking at HPV\u00a0status and\u00a0vaginal paps\u00a0in\u00a0women. In the above study, the ASCUS findings were associated with HPV.\u00a0My guess is that HPV is the culprit and that it seems reasonable to consider HPV and\/or pap screening in women with HPV infection at the time of hysterectomy and later if at risk for getting an HPV infection. But this should be studied.\u00a0And\u00a0it is really important that\u00a0we pursue HPV vaccination rigorously in young women (and men).\n<ul>\n<li>Since\u00a0there\u00a0was a deterioration of HIV markers (CD4 and viral load)\u00a0within 6 months\u00a0of the abnormal pap, perhaps\u00a0should we be\u00a0doing selective paps on those with HIV deterioration, or at certain levels of these counts. Again, it would be good to know prospectively if changes in HIV markers consistently preceded vaginal cytology abnormalities.<\/li>\n<li>This study was done in a\u00a0single population\/demographic area. Is it\u00a0generalizable?<\/li>\n<li>Is there any relationship between numbers of sexual partners, partners infected with HIV, etc. and the\u00a0development\u00a0of VAIN?<\/li>\n<\/ul>\n<\/li>\n<li>So, this study does throw a bit of a wrench into conventional wisdom.\u00a0It is pretty clear that\u00a0there is more of a risk for vaginal cytologic abnormalities in women with HIV who get a hysterectomy for benign reasons than we had thought, and that recommendations be reconsidered given the relatively benign test (pap), and further\u00a0work-up (biopsy). To me, it is not unreasonable to assume\u00a0that for\u00a0a woman\u00a0with\u00a0significant\u00a0abnormalities on vaginal\u00a0biopsy and with pathological deterioration on observation\/local therapy, that definitive therapy be considered.<\/li>\n<li>But, at this point, it does seem reasonable to do vaginal\u00a0pap smears\u00a0on women with HIV and hysterectomy for benign reasons. Unclear what interval. But it seems from the data that these are not very aggressive or rapidly progressive evolution from VAIN to cancer, so likely that they could be done every several years.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Primary Care Corner with Geoffrey Modest MD: Pap Smears Post-Hysterectomy in HIV Positive Women  [&#8230;]<\/p>\n<p><a class=\"btn btn-secondary understrap-read-more-link\" href=\"https:\/\/stg-blogs.bmj.com\/bmjebmspotlight\/2016\/07\/18\/primary-care-corner-with-geoffrey-modest-md-pap-smears-post-hysterectomy-in-hiv-positive-women\/\">Read More&#8230;<\/a><\/p>\n","protected":false},"author":148,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[14283],"tags":[],"class_list":["post-1098","post","type-post","status-publish","format-standard","hentry","category-archive"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/stg-blogs.bmj.com\/bmjebmspotlight\/wp-json\/wp\/v2\/posts\/1098","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/stg-blogs.bmj.com\/bmjebmspotlight\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/stg-blogs.bmj.com\/bmjebmspotlight\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/stg-blogs.bmj.com\/bmjebmspotlight\/wp-json\/wp\/v2\/users\/148"}],"replies":[{"embeddable":true,"href":"https:\/\/stg-blogs.bmj.com\/bmjebmspotlight\/wp-json\/wp\/v2\/comments?post=1098"}],"version-history":[{"count":0,"href":"https:\/\/stg-blogs.bmj.com\/bmjebmspotlight\/wp-json\/wp\/v2\/posts\/1098\/revisions"}],"wp:attachment":[{"href":"https:\/\/stg-blogs.bmj.com\/bmjebmspotlight\/wp-json\/wp\/v2\/media?parent=1098"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/stg-blogs.bmj.com\/bmjebmspotlight\/wp-json\/wp\/v2\/categories?post=1098"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/stg-blogs.bmj.com\/bmjebmspotlight\/wp-json\/wp\/v2\/tags?post=1098"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
