The EuroSIDA study: 25 years of scientific achievements.

The EuroSIDA study was initiated in 1994 and follows adult people living with HIV (PLHIV) in 100 collaborating clinics across 35 countries covering all European regions, Israel and Argentina. The study aims to study the long-term virological, immunological and clinical outcomes of PLHIV and to monitor temporal changes and regional differences in outcomes across Europe. Annually collected data include basic demographic characteristics, information on AIDS- and non-AIDS-related clinical events, and details about antiretroviral therapy (ART), hepatitis C treatment and other medications, in addition to a range of laboratory values. The summer 2016 data set held data from a total of 23 071 individuals contributing 174 481 person-years of follow-up, while EuroSIDA's unique plasma repository held over 160 000 samples. Over the past 25 years, close to 300 articles have been published in peer-reviewed journals (h-index 52), covering a range of scientific focus areas, including monitoring of clinical and virological outcomes, ART uptake, efficacy and adverse events, the influence of hepatitis virus coinfection, variation in the quality of HIV care and management across settings and regions, and biomarker research. Recognizing that there remain unresolved issues in the clinical care and management of PLHIV in Europe, EuroSIDA was one of the cohorts to found The International Cohort Consortium of Infectious Disease (RESPOND) cohort consortium on infectious diseases in 2017. In celebration of the EuroSIDA study's 25th anniversary, this article aims to summarize key scientific findings and outline current and future scientific focus areas.

Sexual acquisition of HIV infection after solid organ transplantation: Late presentation and potentially fatal complications.

INTRODUCTION: While the growing knowledge on HIV among solid organ transplant recipients (SOT) is limited to either pretransplant infection or allograft transmission, there are only sparse reports describing HIV-infection after transplantation through sexual route, the primary mode of transmission in the general population. METHODS: From two different centers, we report nine new cases of HIV infection in SOT recipients attributed to sexual acquisition: eight cases of kidney-transplant recipients and one heart-transplant recipient. FINDINGS: There were nine cases of post-transplant HIV-infection detected among 14 526 transplants performed 1998 to 2015. In 6/9 cases, infection was contracted 5 years after SOT. All but one patient had stable allograft function under immunosuppressive therapy. The main trigger to diagnosis was late CMV disease and sexually transmitted diseases; five patients had CDC-stage 3 HIV infection. In 7/9 patients, virologic response and CD4 recovery were achieved within 3 months after starting antiretroviral therapy (ART). After an average of 3.6 years post diagnosis, 5/9 patients remained alive with well-controlled infection and functioning allograft. CONCLUSION: Sexual acquisition of HIV infection after SOT represents a difficult challenge, as it may occur in any kind of transplant and at any time. The course of infection resembles that of the general population, with life-threatening infectious complications, but good response to ART. Assessment of lifestyle and risk behavior is paramount, as indications may be not disclosed without direct questioning.

Tuberculosis in recipients of solid-organ transplants during 1995-2015 in Cali, Colombia.

SETTING: Tuberculosis (TB) in solid-organ transplants (SOTs) is an important opportunistic infection associated with mortality and graft loss. SOT recipients carry a higher risk of contracting active TB than the general population. Clinical and radiographic presentations are non-specific, and sputum smear and culture have low yields. TB patients with SOTs require standard anti-tuberculosis treatment. However, rifampicin (RMP) use is associated with a 30% rate of acute graft rejection (AGR) and a 20% rate of transplant loss. OBJECTIVE: To determine treatment outcomes in SOT recipients with active TB. DESIGN: A retrospective study of clinical and microbiological data and TB treatment outcomes. RESULTS: Among the 2349 transplants assessed, active TB was detected in 31 recipients; 55% had pulmonary TB and 40% were sputum smear-positive. In 32% of the patients, TB was diagnosed 30 days after symptom onset, 77% of the patients were cured and 10% died. AGR occurred in 13%. CONCLUSION: TB was diagnosed in <30 days. Anti-tuberculosis treatment without RMP (80% vs. 67%; P = 0.48, OR 0.5, 95%CI 0.07-3.55) and with moxifloxacin yielded higher treatment success rates and a lower risk of AGR.

Estimation of renal function by CKD-EPI versus MDRD in a cohort of HIV-infected patients: a cross-sectional analysis.

BACKGROUND: Accurately determining renal function is essential for clinical management of HIV patients. Classically, it has been evaluated by estimating glomerular filtration rate (eGFR) with the MDRD-equation, but today there is evidence that the new Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation has greater diagnostic accuracy. To date, however, little information exists on patients with HIV-infection. This study aimed to evaluate eGFR by CKD-EPI vs. MDRD equations and to stratify renal function according to KDIGO guidelines. METHODS: Cross-sectional, single center study including adult patients with HIV-infection. RESULTS: Four thousand five hundred three patients with HIV-infection (864 women; 19%) were examined. Median age was 45 years (IQR 37-52), and median baseline creatinine was 0.93 mg/dL (IQR 0.82-1.05). A similar distribution of absolute measures of eGFR was found using both formulas (p = 0.548). Baseline median eGFR was 95.2 and 90.4 mL/min/1.73 m2 for CKD-EPI and MDRD equations (p < 0.001), respectively. Of the 4503 measurements, 4109 (91.2%) agreed, with a kappa index of 0.803. MDRD classified 7.3% of patients as "mild reduced GFR" who were classified as "normal function" with CKD-EPI. Using CKD-EPI, it was possible to identify "normal function" (>90 mL/min/1.73 m2) in 73% patients and "mild reduced GFR" (60-89 mL/min/1.73 m2) in 24.3% of the patients, formerly classified as >60 mL/min/1.73 m2 with MDRD. CONCLUSIONS: There was good correlation between CKD-EPI and MDRD. Estimating renal function using CKD-EPI equation allowed better staging of renal function and should be considered the method of choice. CKD-EPI identified a significant proportion of patients (24%) with mild reduced GFR (60-89 mL/min/1.73 m2).
