RESUMO

BACKGROUND: Identifying people with HIV (PWH) at risk for chronic kidney disease, cardiovascular events, and death is crucial. We evaluated biomarkers to predict all-cause mortality and cardiovascular events, and measured glomerular filtration rate (mGFR) slope. METHODS: Biomarkers were measured at enrollment. Baseline and 5-year mGFR were measured by plasma iohexol clearance. Outcomes were a composite criterion of all-cause mortality and/or cardiovascular events, and mGFR slope. RESULTS: Of 168 subjects, 146 (87.4%) had undetectable HIV load. Median follow-up was 59.1 months (interquartile range, 56.2-62.1). At baseline, mean age was 49.5 years (± 9.8) and mean mGFR 98.9 mL/min/1.73m2 (± 20.6). Seventeen deaths and 10 cardiovascular events occurred during 5-year follow-up. Baseline mGFR was not associated with mortality/cardiovascular events. In multivariable analysis, cystatin C (hazard ratio [HR], 5.978; 95% confidence interval [CI], 2.774-12.88; P < .0001) and urine albumin to creatinine ratio (uACR) at inclusion (HR, 1.002; 95% CI, 1.001-1.004; P < .001) were associated with mortality/cardiovascular events. Area under receiver operating curve of cystatin C was 0.67 (95% CI, .55-.79) for mortality/cardiovascular event prediction. Biomarkers were not associated with GFR slope. CONCLUSIONS: uACR and cystatin C predict all-cause mortality and/or cardiovascular events in PWH independently of mGFR.

RESUMO

OBJECTIVES: People who survive after primary cancer are at an increased risk for subsequent primary cancers. We aimed to investigate the possible determinants of second primary cancer (SPC) in HIV-positive cancer survivors. METHODS: This was a multicenter retrospective study using longitudinal data from the French Dat'AIDS cohort. Subjects who developed at least 2 primary cancers were selected. Cancer cases were identified using ICD10 codes and distributed in 3 cancer categories: AIDS-defining cancer (ADC), virus-related non-ADC (VR-NADC), and virus-unrelated-NADC (VU-NADC). The possible determinants considered were the first primary cancer category, sex, age, HIV transmission route, duration of HIV infection follow-up, duration of ART exposure, nadir CD4+ T cell count, and hepatitis C and hepatitis B serostatus. RESULTS: Among the 44642 patients in the Dat'AIDS cohort, 4855 were diagnosed with cancer between 1 December 1983 and 31 December 2015, of whom 444 (9.1%) developed at least 2 primary cancers: 130 ADCs, 85 VR-NADCs, and 229 VU-NADCs. A longer delay between the first primary cancer and the SPC was associated with an increased risk of occurrence of a VR-NADC rather than a secondary ADC. Having had a first primary VU-NADC, an older age, and a longer delay between the HIV diagnosis and the first primary cancer as well as between the first primary cancer and the SPC were associated with an increased risk of VU-NADC rather than ADC. CONCLUSION: SPCs are now a major concern in HIV-positive cancer survivors justifying the development of monitoring strategies after a first cancer.

RESUMO

PURPOSE: Progressive multifocal leukoencephalopathy (PML) is a rare but severe demyelinating disease caused by the polyomavirus JC (JCV) in immunocompromised patients. We report a series of patients with primary immune deficiencies (PIDs) who developed PML. METHODS: Retrospective observational study including PID patients with PML. Clinical, immunological, imaging features, and outcome are provided for each patient. RESULTS: Eleven unrelated patients with PIDs developed PML. PIDs were characterized by a wide range of syndromic or genetically defined defects, mostly with combined B and T cell impairment. Genetic diagnosis was made in 7 patients. Before the development of PML, 10 patients had recurrent infections, 7 had autoimmune and/or inflammatory manifestations, and 3 had a history of malignancies. Immunologic investigations showed CD4+ lymphopenia (median 265, range 50-344) in all cases. Six patients received immunosuppressive therapy in the year before PML onset, including prolonged steroid therapy in 3 cases, rituximab in 5 cases, anti-TNF-α therapy, and azathioprine in 1 case each. Despite various treatments, all but 1 patient died after a median of 8 months following PML diagnosis. CONCLUSION: PML is a rare but fatal complication of PIDs. Many cases are secondary to immunosuppressive therapy warranting careful evaluation before initiation subsequent immunosuppression during PIDs.

RESUMO

BACKGROUND: HCV treatment uptake has drastically increased in HIV-HCV coinfected patients in France since direct-acting antiviral (DAA) treatment approval, resulting in HCV cure in 63% of all HIV-HCV patients by the end of 2015. We investigated the impact of scaling-up DAA on HCV prevalence in the whole HIV population and in various risk groups over the next 10 years in France using a transmission dynamic compartmental model. METHODS: The model was based on epidemiological data from the French Dat'AIDS cohort. Eight risk groups were considered, including high-risk (HR) and low-risk (LR) men who have sex with men (MSM) and male/female heterosexuals, intra-venous drug users, or patients from other risk groups. The model was calibrated on prevalence and incidence data observed in the cohort between 2012 and 2015. RESULTS: On January 1, 2016, 156,811 patients were registered as infected with HIV in France (24,900 undiagnosed patients) of whom 7938 (5.1%) had detectable HCV-RNA (722 undiagnosed patients). Assuming a treatment coverage (TC) rate of 30%/year (i.e., the observed rate in 2015), model projections showed that HCV prevalence among HIV patients is expected to drop to 0.81% in 2026. Sub-analyses showed a similar decrease of HIV-HCV prevalence in most risk groups, including LR MSM. Due to higher infection and reinfection rates, predicted prevalence in HR MSM remained stable from 6.96% in 2016 to 6.34% in 2026. Increasing annual TC rate in HR MSM to 50/70% would decrease HCV prevalence in this group to 2.35/1.25% in 2026. With a 30% TC rate, undiagnosed patients would account for 34% of HCV infections in 2026. CONCLUSIONS: Our model suggests that DAA could nearly eliminate coinfection in France within 10 years for most risk groups, including LR MSM. Elimination in HR MSM will require increased TC.

RESUMO

INTRODUCTION: Morbidity and mortality of Herpes simplex virus encephalitis (HSE) remain high. Relapses of neurological signs may occur after initial clinical improvement under acyclovir treatment. METHODS: We report here a case of post-HSE anti-N-methyl-d-aspartate receptor-mediated encephalitis in an adult and perform a systematic search on PubMed to identify other cases in adults. RESULTS: We identified 11 previously published cases, to discuss diagnostic and therapeutic management. Symptoms in adults are often inappropriate behaviors, confusion and agitation. Diagnosis of anti-NMDA-R encephalitis after HSE is often delayed. Treatment consists in steroids, plasma exchange, and rituximab. Prognosis is often favorable. CONCLUSION: Anti-NMDA-R antibodies should be searched in cerebrospinal fluid of patients with unexpected evolution of HSE. This emerging entity reopens the hot debate about steroids in HSE.

RESUMO

BACKGROUND: A persistent immune activation is observed in gut during HIV-1 infection, which is not completely reversed by a combined antiretroviral therapy (cART). The impact of the time of cART initiation may highly influence the size of the viral reservoir and the ratio of CD4(+)/CD8(+) T cells in the gut. In this study, we analyzed the characteristics of HIV rectal reservoir of long-term treated patients, regarding their blood CD4(+) T cells count at the time of cART initiation. RESULTS: Twenty-four consenting men were enrolled: 9 exhibiting a CD4(+) T cells count >350/mm(3) ("high-level CD4 group") and 15 < 350/mm(3) ("low-level CD4 group") in blood, at the start of cART. An immunophenotypical analysis of T and B cells subpopulations was performed in blood and rectal biopsies. HIV cell-associated DNA loads and qualitative intra-cellular RNA were determined in both compartments. The ratio of CD4(+)/CD8(+) T cells was significantly decreased in the blood but not in the rectum of the "low-level CD4 group" of patients. The alteration in ß7(+) CD4(+) T cells homing was higher in this group and was correlated to a low ratio of CD4(+)/CD8(+) T cells in blood. An initiation of cART in men exhibiting a low-level CD4 count was also associated with an alteration of B cells maturation. HIV blood and gut DNA reservoirs were significantly lower in the "high-level CD4 group" of men. A high HIV DNA level was associated to a detectable intracellular HIV RNA in rectum. CONCLUSIONS: An early initiation of cART could significantly preserve gut immunity and limit the viral reservoir constitution.

RESUMO

OBJECTIVE: To evaluate the mutational patterns on the pol gene of the main HIV-1 strain archived in cell genome of 10 chronically infected men according to their clinical and therapeutic history. The genotyping resistance profiles were compared between the first blood plasma available at the time of HIV diagnosis and rectal biopsies and PBMC sampled 1-5 years after the initiation of combined antiretroviral therapy (cART). METHODS: HIV-1 RNA and cell-associated HIV-1 DNA were quantified by Abbott Real-Time HIV-1 and Generic HIV® DNA cell (Biocentric) assays. The mutations in protease and reverse transcriptase genes were assessed by the Trugene® assay (Siemens). The C2V3 region was amplified to determine the viral tropism. RESULTS: In 9 patients, slight or no differences were observed between the 3 resistance profiles. Those mostly detected were related to the resistance to nucleos(t)ide (D67N, L210W, T215A, T69D) and nonnucleoside (K103N, V106I, V179I) inhibitors. In 1 rilpivirine-treated patient, the M230I mutation was detected in PBMC. No change of viral tropism was observed between samples. CONCLUSION: These data suggest that resistance mutations harbored by the main HIV strain in plasma at the time of diagnosis are durably archived in DNA cells whatever the delay between infection and initiation of therapy in patients well controlled by cART.

RESUMO

Guillain-Barré syndrome (GBS) is an autoimmune disease that can be triggered by different infectious agents. Here we report the case of a 26-year-old Algerian woman who developed GBS associated with a Mycobacterium bovis cervical lymphadenitis. Following intravenous immunoglobulin therapy, the patient's neurologic state returned to normal after 3 months. The lymphadenitis responded more slowly to the antituberculous treatment and an excision of necrotic cervical lymph nodes had to be performed four times. Antibiotics were administered for 16 months: ethambutol was stopped after 2 months, and rifampicin and isoniazid pursued for 14 months. An extensive etiological investigation showed that, in this case, the only likely infectious trigger GBS was the concomitant M. bovis infection. To our knowledge, this is the first report of GBS triggered by M. bovis. We performed a literature review revealing that the association between tuberculosis and Guillain-Barré syndrome is very rare (only seven cases previously reported) but is not coincidental. Physicians should be aware that tuberculosis can be a cause of GBS.

RESUMO

BACKGROUND: We aimed to describe the prevalence and spectrum of second primary cancer (SPC) in HIV-positive cancer survivors. METHODS: A multicenter retrospective study was performed using longitudinal data from the French Dat'AIDS cohort. Subjects who had developed at least two primary cancers were selected. The spectrum of SPCs was stratified by the first primary cancer type and by sex. RESULTS: Among the 44,642 patients in the Dat'AIDS cohort, 4855 were diagnosed with cancer between 1 December 1983 and 31 December 2015, of whom 444 (9.1%) developed at least two primary cancers. The most common SPCs in men were non-Hodgkin lymphoma (NHL) (22.8%), skin carcinoma (10%) and Kaposi sarcoma (KS) (8.4%), and in women the most common SPCs were breast cancer (16%), skin carcinoma (9.3%) and NHL (8%). The pattern of SPCs differed according to first primary cancer and by sex: in men, NHL was the most common SPC after primary KS and KS was the most common SPC after primary NHL; while in women, breast cancer was the most common SPC after primary NHL and primary breast cancer. CONCLUSION: The frequency and pattern of subsequent cancers among HIV-positive cancer survivors differed according to the first primary cancer type and sex.

RESUMO

BACKGROUND: We aimed to evaluate the incidence rates between 2010 and 2015 for invasive cervical cancer (ICC), breast cancer (BC), and colorectal cancer (CRC) in people living with HIV (PLWH) in France, and to compare them with those in the French general population. These cancers are targeted by the national cancer-screening program. SETTING: This is a retrospective study based on the longitudinal data of the French Dat'AIDS cohort. METHODS: Standardized incidence ratios (SIR) for ICC and BC, and incidence rates for all three cancers were calculated overall and for specific sub-populations according to nadir CD4 cell count, HIV transmission category, HIV diagnosis period, and HCV coinfection. RESULTS: The 2010-2015 CRC incidence rate was 25.0 [95% confidence interval (CI): 18.6-33.4] per 100,000 person-years, in 44,642 PLWH (both men and women). Compared with the general population, the ICC incidence rate was significantly higher in HIV-infected women both overall (SIR = 1.93, 95% CI: 1.18-3.14) and in the following sub-populations: nadir CD4 ≤ 200 cells/mm3 (SIR = 2.62, 95% CI: 1.45-4.74), HIV transmission through intravenous drug use (SIR = 5.14, 95% CI: 1.93-13.70), HCV coinfection (SIR = 3.52, 95% CI: 1.47-8.47) and HIV diagnosis before 2000 (SIR = 2.06, 95% CI: 1.07-3.97). Conversely, the BC incidence rate was significantly lower in the study sample than in the general population (SIR = 0.56, 95% CI: 0.42-0.73). CONCLUSION: The present study showed no significant linear trend between 2010 and 2015 in the incidence rates of the three cancers explored in the PLWH study sample. Specific recommendations for ICC screening are still required for HIV-infected women and should focus on sub-populations at greatest risk.

RESUMO

BACKGROUND: Cancer risk is higher in people living with HIV (PLWH) compared with the general population, and cancers related to age are expected to be most prevalent. METHODS: We determined the spectrum and incidence rates of AIDS-defining cancers (ADC) and non-AIDS-defining cancers (NADC) and of lung, Hodgkin lymphoma (HL), head and neck (HNC), colon-rectum, anal, liver, breast, prostate, and urinary bladder cancers between January 2010 and December 2015 in the French Dat'AIDS cohort. Incidence rates were calculated by year and compared using the χ 2 test for linear trend. Standardized incidence ratios [SIR (95% confidence interval)] were calculated relative to the French general population. RESULTS: Among 44,642 patients, corresponding to 180,216.4 person-years (PY), 1,440 cancer cases occurred in 1,314 patients. ADC incidence was 191.4 (172.3-212.7)/105 PY and declined over time overall and in men, whereas NADC incidence was higher [548.8 (515.6-584.1)/105 PY] and did not change. In men, non-Hodgkin lymphoma was the most common cancer, but prostate cancer had the highest incidence among NADCs. Breast cancer was the most common cancer in women. SIRs were higher for cervical cancer [1.93 (1.18-3.14)], HNC in women [2.4 (1.4-4.2)], liver [overall: 3.8 (3.1-4.6); men: 3.2 (2.5-4.0); women: 12.9 (8.3-20.0)], and HL [overall: 13.8 (11.1-17.1); men: 16.2 (12.9-20.4); women: 6.2 (3.22-11.9)] but lower for lung [overall: 0.7 (0.6-0.9); men: 0.7 (0.5-0.8)], prostate [0.6 (0.5-0.7)], and breast cancers [0.6 (0.4-0.7)]. CONCLUSIONS: Spectrum of NADCs has changed, with prostate and breast cancers becoming the most common despite their lower SIR. IMPACT: These results confirm the need to maintain regular epidemiologic cancer monitoring in order to update screening guidelines.

RESUMO

OBJECTIVE: High hepatitis C virus (HCV) treatment uptake combined with effective direct-acting antiviral-based regimens resulted in a dramatic decline of HCV infection in French people living with HIV (PLWH). We assessed the yearly incidence of new HCV infection in PLWH enrolled in the large French Dat'AIDS cohort from 2012 to 2016 with a specific focus on MSM. METHODS: The incidence of new HCV infection was determined yearly in HCV-negative PLWH with serological follow-up during 2012-2016. The incidence of HCV reinfection was determined in patients who were cured of a previous infection. RESULTS: Among 40 714 PLWH, HCV status was available in 38 217 (94%). A total of 5557 PLWH (15%) were HCV infected at first time-point, 82% of whom were cured of HCV by the end of 2016. Among 21 519 HCV-negative PLWH with serological follow-up (63 449 patient-years), 219 first HCV infections occurred (MSM: 188, others: 31). Similarly, among 3406 patients who were cured of a previous infection (10 602 patient-years), 73 reinfections occurred (MSM: 51, others: 22). From 2012 to 2016, the incidence of a first infection in MSM rose from 0.5 to 0.92% patient-years, whereas the incidence or reinfection remained stable (2.52-2.90% patient-years). CONCLUSION: Despite a high HCV treatment uptake and cure rate, the incidence of first HCV infection regularly increased in French HIV-positive MSM between 2012 and 2016. The incidence of reinfection fluctuated but remained constantly higher than the incidence of first infection, suggesting that a subgroup of MSM pursued high-risk practices following cure of a first infection.

RESUMO

INTRODUCTION: Chronic kidney disease (CKD) is a prevalent comorbidity in persons living with HIV infection (PLWH) associated with an increase in cardiovascular morbidity and all-cause mortality. Furthermore, early diagnosis of CKD is difficult in PLWH. Areas covered: We reviewed the main diagnostic tools for CKD in PLWH, and discussed their strengths and limits. We performed a literature search on PubMed to identify reviews and clinical trials dealing with attractive kidney biomarkers of CKD in PLWH, with the following key words: 'HIV AND kidney', 'HIV AND Kidney biomarkers', 'CKD AND Kidney biomarkers'. Expert commentary: Currently, CKD diagnosis is based on the estimation of Glomerular Filtration Rate (GFR), and measurement of proteinuria by urine protein/creatinine ratio (uPCR). These parameters are independent and complementary predictors of outcomes. GFR estimates are lacking in accuracy in PLWH. The best GFR estimate is CKD-EPI study equation. Moreover, low-grade proteinuria is associated with an increased risk of kidney disease progression in PLWH, and guidelines derived from the general population may lack sensitivity. Different biomarkers of kidney diseases like N-acetyl beta glucosaminidase (NAG), Kidney Injury Molecule-1 (KIM-1), and Alpha-1-microglobulin may predict kidney disease progression and mortality in PLWH. Others may help clinicians detect antiretroviral-induced tubulopathy, or predict cardiovascular events. More studies are needed to validate the routine use of these types of biomarkers.

RESUMO

OBJECTIVES: Direct-Acting Antivirals (DAAs) opened a new era in HCV treatment. We report the impact of HCV treatment in French HIV-HCV coinfected patients. METHODS: All HIV-HCV patients from the Dat'AIDS cohort followed between 2012 and 2015 were included. HCV status was defined yearly as naive, spontaneous cure, sustained virological response (SVR12), failure or reinfection. RESULTS: Among 32,945 HIV-infected patients, 15.2% were positive for anti-HCV antibodies. From 2012 to 2015, HCV incidence rate increased from 0.35%PY to 0.69%PY in MSM, while median incidence was 0.08%PY in other patients. Median reinfection rate was 2.56%PY in MSM and 0.22%PY in other patients. HCV treatment initiation rate rose from 8.2% in 2012 to 29.6% (48.0% in pre-treated patients vs 22.6% in naïve patients). SVR12 rate increased from 68.7% to 95.2%. By the end of 2015, 62.7% of the patients were cured either spontaneously or following SVR. CONCLUSIONS: HCV treatment dramatically increased in HIV-HCV patients in France from 2012 to 2015 resulting in HCV cure in nearly two-thirds of the patients in this cohort. Combined with a declining HCV prevalence, the prevalence of active HCV infection among HIV patients will drastically decrease in the forthcoming years.

RESUMO

Localized macronodular tuberculosis of the liver is rare. In this location antituberculosis therapy results in a favorable clinical evolution in 100% of cases. We report a pseudo-tumoral form of this condition with no specific clinical, biological or radiological data. After ultrasound guided needle aspiration cytology suggesting metastasis, the correct diagnosis was obtained on liver biopsy after laparotomy. After what was probably inadequate therapy, the enlargement of several hepatic and splenic macronodules was observed. After two years and eight months, the clinical condition of the patient was good but radiological features remained. The risk of diagnostic errors and the therapeutic difficulties in the zones where the incidence of tuberculosis is low should be noted.

RESUMO

Human immunodeficiency virus (HIV)-infected patients remain at increased risk of infection including vaccine-preventable diseases. Vaccines are therefore critical components in the protection of HIV-infected patients from an increasing number of preventable diseases. However, missed opportunities for vaccination among HIV-infected patients persist and vaccine coverage in this population could be improved. This article presents the French recommendations regarding immunization of HIV-infected adults in the light of the evidence-based literature on the benefits and the potential risks of vaccines among this vulnerable population.

RESUMO

BACKGROUND: The semen of HIV-1 infected men represents the main vector of HIV-1 spread following sexual transmission of cell-free or cell-associated virions. OBJECTIVE: The present study aimed to assess the impact of HAART on HIV-1 RNA/DNA and on inflammatory environment in the semen of long-term HAART-experienced men. METHODS: Forty-five paired samples of semen and blood were obtained from 37 consenting men, 10 untreated and 27 under HAART. Blood and seminal HIV RNA and DNA loads were quantified by the Abbott RealTime m2000rt assay and an inhouse real-time PCR protocol, respectively. Tat/rev/nef intra-cellular mRNA was tested by qualitative PCR. Interleukin (IL)- 1ß, IL-2, IL-6, IL-7, IL-8, IL-10, GM-CSF and TNFα were quantified in 20 paired samples by Bio-plex® assay. RESULTS: No semen was found HIV RNA positive in men under HAART. Twenty-six percent of semen samples from HAART-experienced men remained positive for HIV DNA. Seminal HIV DNA was significantly associated with the duration of infection and the HIV DNA load in blood. No seminal mononuclear cells were found positive for intracellular HIV RNA in HAART experienced men. All the tested chemokines exhibited significantly higher concentration in semen than in blood in both treated and untreated men. No effect of HAART on cytokines/chimiokines loads was observed. CONCLUSION: These results demonstrate the efficacy of HAART on the reduction of seminal RNA HIV-1 loads despite the persistence of local inflammation. Moreover, in our hands the seminal cell-associated virus reservoir was not reactivated in an inflammatory environment was not productive and its reactivation seems unlikely.
