Background The contribution of HIV-infection to periodontal disease (PD) is poorly understood. Forty (40) topics with median 2.7 months on HAART and median nadir CD4+ T-cell count of 212 cells/l completed a median 3 visits. Over 24 months, CD4+ T-cell count increased by a mean 173 cells/l (p<0.001) and HIV RNA decreased by 0.5 log10 copies/ml (p<0.001); concurrently, PPD, CAL and BOP decreased by a mean 11.7%, 12.1%, and 14.7% respectively (all p<0.001). Lower nadir CD4+ T-cell count was associated with worse baseline REC (-6.72%; p=0.04) and CAL (9.06%; p<0.001). Further, lower nadir CD4+ T-cell count was associated with a greater relative longitudinal improvement in PPD in subjects with higher baseline levels of (p=0.027), and BOP in subjects with higher baseline levels of or (p=0.001 and p=0.006 respectively). Longitudinal changes from baseline in CD4+ T-cell count and level of HIV RNA were not independently associated with longitudinal changes in any medical markers of PD. Summary Degree of immunosuppression was associated with baseline gingival downturn. After HAART initiation, steps of active PD improved most in those with lower nadir CD4+ T-cell counts and higher baseline levels of specific periodontopathogens. Nadir CD4+ T-cell count differentially influences periodontal disease both before and after HAART in HIV-infected adults. Background While HIV/AIDS is considered a modifier of periodontal disease (PD) [1,2], the mechanisms of this connection are poorly recognized. Clearly, immunosuppression can potentiate PD, as evidenced by reports of florid examples of HIV-associated gingival/periodontal disease during the early days of HIV outbreak in the United States [3,4]. Recently, inside a cross-sectional evaluation of 112 HIV+ adults, our group found that ever possessing a CD4+ T-cell count CUDC-907 below 200 cells/l conferred approximately twice the risk for traditionally defined PD as did cigarette smoking, a known strong risk element for PD . Actually in the era of highly active antiretroviral therapy (HAART), the prevalence of traditionally defined PD within cohorts of mainly African American HIV+ adult cohorts has been high, ranging from 66% to >90% [5,6] depending on the definition of PD used. Because African People in america are disproportionately infected with HIV, the public health relevance of traditionally-defined PD in HIV+ adults is definitely significant both in terms of the population affected and individual morbidity; however, the issue remains underappreciated and under-recognized. There are several methodological limitations in earlier studies proposing a low level of PD in HIV+ adult cohorts, as detailed in our 2009 statement. In our 2011 longitudinal statement of 43 HIV+ individuals on HAART, we found that PD improved significantly during immune reconstitution on HAART. We consequently hypothesized that longitudinal improvement in CD4+ T-cell count and/or decreased level of HIV RNA would be associated with longitudinal improvement in medical steps of PD. To address this hypothesis, we prolonged the analysis of our earlier statement by modeling the effect of nadir CD4+ T cell depend and the longitudinal switch in CD4+ T cell depend and level of HIV RNA on medical steps of PD. We CUDC-907 found that nadir CD4+ T cell count influences periodontal disease in HIV-infected adults both before and after HAART initiation, and that this influence varies prior to and after HAART initiation. Methods Study Design This was a prospective observational study of adult subjects recruited from three outpatient HIV medical clinics in Cleveland, Ohio as previously described[5,8]. IRB authorization was from University or college Hospitals Case Medical Center (UHCMC). Most participants were self-referred; all subjects signed a written UHCMC IRB-approved educated consent document. Exclusion criteria included evidence of cardiovascular disease, a history of Type I or II diabetes mellitus, fewer than 20 teeth, uncontrolled systemic ailments, analysis or treatment of malignancy Rabbit Polyclonal to Claudin 2. in the past five years, pregnancy, and need for antibiotic prophylaxis prior to dental care CUDC-907 as per the American Dental care Association (ADA) and additional recommendations[9,10]. Inclusion criteria were: medication-compliant adult subjects, age 18 or older, who were taking highly active antiretroviral therapy (HAART) for < 2 years at baseline. HAART was defined previously as a treatment routine that included at least three different antiretroviral medicines from at least two different classes. All subjects were seen for evaluation and PD measurement at baseline and at one.
