Abstract

There is a lack of updated estimates of HIV-2 infection in Italy. Moreover, lack of standardized HIV-2 viral load (VL) and drug resistance tests challenges clinical practice. Among 2941 HIV-positive patients followed in our center (Brescia, Northern Italy), 220 (7.5%) were African at the beginning of the study period. We assessed a population of 151 HIV-Ab positive patients (141 of African origin), presenting for routine blood testing from January 2006 to May 2007. Those found infected with HIV-2 started an appropriate disease management with HIV-2 VL and genotypic drug resistance testing. Sixteen of 151 (10.6%) patients were positive for HIV-2. Of those 16 patients, 14 carne from Africa. Among 7 experienced patients, 1 was responding to nelfinavir and 4 to lopinavir/ritonavir-containing regimens. Two patients were failing treatment: 1 patient was switched to a saquinavir/ritonavir-containing regimen and responded. The remaining patient switched to lamivudine+atazanavir+saquinavir+ritonavir did not respond, having had previous experience to multiple ineffective drugs, resulting in a very complex HIV-2 drug-resistance pattern. Accurate screening programs and integration of virological tools must be implemented urgently, given the high prevalence of HIV-2, particularly in immigrant patients.

Abstract

Data from 197 patients for whom highly active antiretroviral therapy (HAART) failed, who started a new regimen chosen under the guide of resistance testing results interpreted by experts, were retrospectively studied, provided that at least 2 determinations of adherence and plasma drug concentrations were performed during the follow-up. Univariate and multivariable logistic regression analyses were conducted, using confirmed virologic response at week 24 as outcome measure (i.e., achievement of undetectable HIV plasma viral load at any time point before week 24 and its maintenance up to week 24). Suboptimal drug concentrations (odds ratio [OR]: 0.3; 95% confidence interval [CI] 0.2-0.7; p = 0.006) and suboptimal adherence (OR: 0.4; 95% CI 0.2-0.8; p = 0.014) were both negative independent predictors of sustained virologic response, while the use of boosted protease inhibitor-containing regimens resulted to be protective (OR: 2.4; 95% CI 1.1-5.3; p = 0.032).

Abstract

Abstract Background Quantitative real-time PCR assays, which are more rapid and practical than pp65 antigenemia determination, are progressively becoming the preferred method for monitoring Human Cytomegalovirus (HCMV) reactivation. However, the relationship between HCMV DNA and antigenemia levels is still under investigation. The aim of this study was to analyse the relationship between HCMV DNA and pp65 antigenemia levels in order to identify clinically useful threshold values for the management of patients. Methods 475 consecutive samples from 156 immunosuppressed patients were tested for HCMV by pp65 antigenemia and Real-time PCR assay. Results 136 out of 475 consecutive samples derived from 48 patients showed evidence of HCMV infection. HCMV DNA was detected in 106 samples, pp65 antigen in 3, and both markers in 27. pp65 antigen detection was associated with higher HCMV DNA levels. The cut-off HCMV DNA level that best predicted pp65 antigenemia in this series of samples was 11,500 copies/ml, but different threshold levels could be observed for specific groups of patients. HCMV disease was observed in 5 out of 48 patients with active HCMV infection. The presence of clinical symptoms was associated with positive pp65 and with higher antigenemia levels. Higher HCMV DNA load at the onset of viral replication was correlated to the development of clinical symptoms. Conclusion Both pp65 antigenemia and HCMV DNA load can be useful for the prospective monitoring of immunocompromised subjects. Specific cut-off levels capable of triggering preemptive antiviral treatment should be determined in accordance to the type of test used and the characteristics of patients and prospectively validated.

Abstract

Abstract Background Epstein-Barr virus (EBV) DNA load monitoring is known to be useful for the diagnosis and monitoring of EBV-associated diseases. The aim of this study is to compare the performance of two real-time PCR assays for EBV DNA: a commercial kit as the Q-EBV Real-Time System (Q-EBV PCR, Amplimedical, Turin, Italy) and an in-house assay (EBV RQ-PCR). Results The range of linearity and the degree of precision of the two assays were similar. The clinical sensitivity of Q-EBV PCR was higher for reference samples containing less than 1,000 EBV DNA copies/ml. The absolute quantitative results of the two methods were statistically correlated (R2 = 0.7789; p < 0.0001), with the systematic overestimation by EBV RQ-PCR possibly linked to different amplification efficiency in calibration standards. Conclusion Both the commercial and the in-house assay may be appropriate for clinical use, but common standards are advisable for comparable absolute values, as these would improve the clinical utility of EBV DNA load measurement.
