Prevalence of chronic hepatitis C infection in the general population: results from a national survey, Romania, 2020 to 2023.

IntroductionA national study from 2006 to 2008 showed a high antibody prevalence of 3.2% against hepatitis C virus (HCV) in Romania, but more recent epidemiological data on hepatitis C prevalence are lacking.AimWe aimed to estimate the current prevalence of HCV antibodies (anti-HCV) and chronic HCV infection in the general adult population in Romania, as a crucial element in monitoring progress towards eliminating hepatitis C.MethodsWe used anonymised leftover sera from a SARS-CoV-2 survey conducted between July and October 2020 (n = 2,100), supplemented with sera collected prospectively between July 2022 and March 2023 (n = 574). These included sera collected from adults visiting laboratories for routine medical check-ups. Sera were tested for anti-HCV and HCV core antigen and classified according to anti-HCV and chronic infection status.ResultsOf the total 2,674 specimens tested, 44 were anti-HCV-positive with a weighted anti-HCV prevalence of 1.4% (95% CI: 1.0-1.9), and 29 were HCV core antigen-positive with a weighted prevalence of chronic infection of 0.9% (95% CI: 0.5-1.2). The prevalence of chronic infection did not differ significantly between men and women. It was higher in persons 60 years and older (2.0%; 95% CI: 1.1-3.0) and in specimens from the North-East region (2.2%; 95% CI: 0.8-3.7).ConclusionAlthough the overall HCV prevalence in Romania is currently low, targeted screening, prevention measures and treatment scale-up are needed especially for the population 60 years and older and in the north-eastern part of the country to achieve the goal of ending the hepatitis C epidemic.

Prevalence of chronic hepatitis C infection in the general population: results from a national survey, Estonia, July to December 2022.

IntroductionObtaining epidemiological data on chronic hepatitis C virus (HCV) infection is essential to monitor progress towards the hepatitis C elimination targets.AimWe aimed to estimate the prevalence of chronic HCV and the seroprevalence of HCV in the adult general population in Estonia.MethodsThis cross-sectional study, conducted between 12 July and 6 December 2022, included anonymised residual sera collected prospectively from patients 18 years and older visiting a general practitioner in all counties of Estonia. Specimens were considered HCV-seropositive if they tested positive for HCV antibodies by enzyme-linked immunoassay, confirmed by line-immunoblot assay. Chronic HCV infection was determined by positive RT-qPCR.ResultsWe tested a total of 4,217 specimens. The estimated HCV seroprevalence and prevalence of chronic HCV infection were 1.8% (95% CI: 1.4-2.2) and 0.8% (95% CI: 0.5-1.1), respectively, with ca 8,100 persons estimated to have chronic HCV infection in the general adult population of Estonia. No statistically significant differences in the prevalence of chronic HCV infection were observed between sexes, counties or age groups, with the highest prevalence rates observed in men (sex ratio: 1.7), Ida-Virumaa County (1.8%; 95% CI: 0.8-3.6) and the age group 40-49 years (1.7%; 95% CI: 0.9-2.9).ConclusionThis study found an overall low prevalence of chronic HCV infection in Estonia. Continued efforts should be made for the targeted screening, diagnosis and treatment of individuals with chronic HCV infection to achieve hepatitis elimination targets.

Dietary Knowledge and Eating Habits among Patients with Type 2 Diabetes in Lebanon.

Little is known about the dietary knowledge (DK) and eating habits (EHs) of patients with type 2 diabetes (T2D) in Lebanon. Therefore, the aim of this study was to assess the DK and EH of the population with T2D and determine their associated factors. A cross-sectional survey enrolling 351 patients with T2D was carried out, using the snowball sampling technique. The survey used the UK Diabetes and Diet Questionnaire and the Dietary Knowledge questionnaire to assess participants' EH including the frequency of consumption of certain foods and their knowledge of food groups and food choices. While a higher DK index indicated better knowledge, a higher EH index indicated less healthy EH. Independent sample T-test and Mann-Whitney test were used for dichotomous variables, and ANOVA and Kruskal-Wallis tests were used for polytomous variables. Correlation analysis tested the association between two continuous variables. Two multiple linear regression models were used to identify factors associated with DK and EH. Overall, 67% of participants had good or adequate DK, and around 25% and 75% of them had healthy and less healthy EH, respectively. Better knowledge was significantly related to occupation, BMI, presence of comorbidities, and HbA1c testing during the last 3 months. Higher family income, physical activity, family history of diabetes, receiving help in medication administration from family or friends, and higher DK level were factors associated with healthier EH. Nutrition education and awareness campaigns aimed at patients and their families are needed to empower patients with adequate DK and skills to facilitate the adoption of healthy EH.

HPV Vaccination Prevalence among Lebanese Female University Students: A Cross-Sectional Study.

Background: Cervical cancer is the fourth most common cancer in women, worldwide. Most often, cervical cancer is caused by a human papillomavirus (HPV) infection. A lack of studies concerning HPV knowledge and vaccination among the Lebanese population is noticed. We aim to assess the prevalence of HPV vaccine administration among female university students in Lebanon alongside determining the predictors influencing vaccine uptake. Lastly, knowledge scores concerning HPV and HPV vaccination are also computed. Methods: This is a cross-sectional analytical study. It is an anonymous, online-based, close-ended questions survey conducted between the 24th of February 2021 and the 30th of March 2021. Our questionnaire was addressed to females aged between 17 and 30 years and enrolled in a Lebanese university. The collected data were analyzed using Statistical Package for Social Sciences (SPSS) v.26. We used bivariate analysis to compare the rate of vaccination with different variables. We used the chi-square test for categorical variables and Student's t-test for continuous variables. Logistic linear regression was conducted between the state of vaccination and other statistically significant variables from the bivariate analysis. Results: We have received a total of 454 questionnaires. Among the respondents, only 18.9% had received a minimum of one dose of the HPV vaccine. The mean age of up taking the first dose of the vaccine was 17.5 years. In addition, 48% of the respondents were not willing to take the HPV vaccine during the upcoming year. Barriers to not taking the HPV vaccine were mainly the low levels of knowledge concerning HPV and its vaccine. In the multivariate analysis, three predictors were found to affect the rate of HPV vaccination: university type, paternal educational level, and HPV vaccine knowledge score. In detail, a student enrolled in a public university had 77% likelihood of not being vaccinated. Furthermore, female students with a paternal educational level higher than a university degree had 88% probability of being vaccinated. Finally, every increase in the HPV vaccination knowledge of one point increased the likelihood of being vaccinated by 37%. Conclusion: A low vaccination rate among female university students in Lebanon was noticed in our study. In addition, a lack of HPV and HPV vaccine knowledge was found in our population. An awareness campaign alongside public vaccination programs is recommended in order to accomplish higher rates of HPV immunization.

A cross-sectional study of knowledge, attitude, behaviour and preventive measures for COVID-19 infection in Lebanon.

Background: The World Health Organization has often reiterated its recommendations for the prevention of COVID-19, however, the success of these measures largely depends on public knowledge and attitudes. Aims: This study assessed the relationship between knowledge, attitude, behaviour and preventive measures for COVID-19 infection in a Lebanese population. Methods: This cross-sectional study was conducted between September and October 2020 using the snowball sampling technique and an online self-administered questionnaire. The questionnaire had 4 parts targeting sociodemographic characteristics; medical history; knowledge, attitude and practices (preventive measures and behaviours related to COVID-19); and mental health variables such as psychological distress. Two models were derived using multivariable binomial logistic regression to optimize the picture of COVID-19 correlates. Results: Our sample comprised 1119 adults. Being older, female, a regular alcohol consumer, waterpipe smoker, having low level of education, low family income, and having contact with a COVID-19 patient correlated with increased odds of ever having been diagnosed with COVID-19. Participants who had ever been diagnosed with COVID-19 had a significantly better knowledge and a higher risky practice scale [adjusted odds ratio (ORa) = 1.49; 95% CI 1.27-1.74; P < 0.001; and ORa = 1.04; 95% CI 1.01-1.08; P = 0.024, respectively]. Conclusion: The most important predictors of COVID-19 infection appear to be generally well-known among the general population, however, their knowledge and adherence to preventive measures should be continuously re-evaluated. This study highlights the need for greater awareness to improve precautionary behaviours among the public.

Effect of an educational intervention among Lebanese dentists on antibiotic prescribing: a randomized controlled study.

OBJECTIVES: To investigate whether an educational intervention could improve antibiotic prescribing among Lebanese dentists and assess antibiotic prescribing patterns regarding international guidelines. MATERIALS AND METHODS: An interventional randomized controlled trial was conducted from the first of April to the end of August 2017. This was an oral presentation of about 20 min based on a review of the literature and the international guidelines. Sixty dentists specializing in oral dental surgery or general practitioners participated in this study. All the patients who took a consultation over 2 months were involved. RESULTS: In this study, 950 antibiotic prescriptions were analyzed. A change was found only in antibiotics prescribed for tooth extraction and tooth extraction (impacted tooth). The intervention was impactful in raising the mean percentage of prescriptions compliant with indication and with the choice regarding antibiotics prescribed for prophylactic reasons. A dentist in the intervention group would have after the intervention period a mean percentage of prescriptions compliant with indication and with choice of 31.7% and 20.7%, respectively, above one in the control group. Despite the decrease in the overall number of antibiotics prescribed by dentists in the intervention group over time, this does not suggest that this was solely due to the effect of the intervention. CONCLUSION: This study highlights the importance of continuing medical education to optimize antibiotic use in dentistry. CLINICAL RELEVANCE: This study can serve as the basis for a future audit, training, and feedback intervention to increase dentists' awareness of recommended guidelines and optimal antibiotic use.

Assessment of COVID-19 vaccines acceptance in the Lebanese population: a national cross-sectional study.

BACKGROUND: Vaccines have become the best weapon for epidemic prevention and control in the absence of standard approved effective therapies. However, skepticism about the vaccine efficacy and safety is constantly reported. To our knowledge, there has been no study assessing COVID-19 vaccine acceptance in Lebanon. The primary objective of this survey is to assess the COVID-19 vaccines' acceptance and its related determinants in the Lebanese population. METHODS: A cross-sectional study was conducted in Lebanon from February 16 through February 25, 2021. Data was collected using an online questionnaire via social media platforms using the snowball technique. The questionnaire consisted of 47 questions related to sociodemographic and medical history, COVID-19 experience, knowledge, practice, and beliefs towards COVID-19 vaccines, including vaccines acceptance. Binary logistic regression was performed to identify factors associated with vaccine acceptance. RESULTS: A total of 1209 questionnaires were completed; around 63.4% have reported their acceptance for receiving the COVID-19 vaccine, while only 57% of participants registered themselves on the national platform. The multivariable analysis showed that a higher knowledge scale, living in an urban residential area, having hypertension, not having a food allergy, reporting a higher fear to experience COVID-19 infection, and receiving or wanting to receive influenza vaccine, were positive predictors of COVID-19 vaccines acceptance. CONCLUSIONS: Our findings support the need to improve knowledge about COVID-19 infection and vaccination through education and awareness programs. Specifically residents of rural areas should be targeted to optimize COVID-19 vaccine acceptance among the Lebanese population.

Knowledge, use and practices of licensed dietitians related to dietary supplements in Lebanon.

OBJECTIVE: To evaluate Lebanese licensed dietitians' knowledge, prevalence of use and recommendation of dietary supplements (DS), and their associated factors. DESIGN: Cross-sectional survey. SETTING: Dietitians across Lebanon were contacted through the telephone and were asked to participate in the study. An online self-administered questionnaire was designed and sent to dietitians either by email or by WhatsApp, between 4 March and 4 May 2020. PARTICIPANTS: This study included 319 dietitians randomly selected from the dietitians' list that was provided by the Lebanese Ministry of Public Health. RESULTS: Around 75 % of dietitians had a knowledge score above 50 %. Overall, 73·7 % of them have used DS and 46·1 % have recommended them. Higher knowledge score was associated with less years of experience, using scientific articles as source of information on DS, and participating in research. Resorting to pharmacists was significantly associated with both nutrient supplements (NS) and herbal supplements (HS) use, whereas referring to health food stores was associated with HS use only. NS recommendation to patients was associated with personal NS use (OR = 3·38, P < 0·001), considering pharmacists as a source of information on DS (OR = 2·29, P = 0·01) and discussing DS with patients (OR = 3·82, P = 0·01). Having personally used HS (OR = 12·23, P < 0·001) and having discussed DS with patients (OR = 8·51, P = 0·01) increased the likelihood of recommending HS. CONCLUSIONS: A proper DS education, the elaboration of national scientific guidelines and the implementation of concise laws regarding the regulations of DS would play a crucial role in supporting dietitians' practices and improving the quality of patient care with respect to DS.

Acceptance of COVID-19 vaccination and its determinants among Lebanese dentists: a cross-sectional study.

BACKGROUND: Dentists are at high risk of exposure to occupational Coronavirus Disease 2019 (COVID-19). Since vaccination is crucial to control COVID-19 pandemic, we aimed to assess COVID-19 vaccination acceptance and its determinants among Lebanese practicing dentists. METHODS: A cross-sectional online study was conducted between February 15 and 22, 2021, among dentists practicing in Lebanon. Prevalence of COVID-19 vaccine acceptance was estimated. A multivariable modified Poisson regression model was used to explore determinants of COVID-19 vaccine acceptance. RESULTS: In total, 86% of participants were willing to receive or have already received a COVID-19 vaccine. Having received the influenza vaccine during the COVID-19 pandemic was linked to a 12% increase in the COVID-19 vaccination acceptance rate. In addition, participants having moderate and high COVID-19 vaccination knowledge levels were more likely to accept receiving the vaccine, and participants whose fear of COVID-19 level was high were more likely to accept receiving the vaccine compared to those having a low fear level. Contrarily, those who visit the medical doctor only when needed and once a year were less likely to accept COVID-19 vaccine compared to participants who routinely visit the medical doctor. CONCLUSIONS: Our study showed a high level of acceptance of COVID-19 vaccination among Lebanese practicing dentists. And since knowledge about COVID-19 vaccination was associated with the vaccine acceptance, it should be improved and updated to further increase the acceptance rate. High acceptability of COVID-19 vaccination among dentists is expected to have a positive impact among the population in terms of increasing awareness and vaccine uptake.

Determinants of knowledge and prevention measures towards COVID-19 pandemic among Lebanese dentists: a cross sectional survey.

BACKGROUND: Coronavirus Disease 2019 (COVID-19) is a major global threat. Healthcare professionals including dentists are facing real challenges during this pandemic. This study aimed to evaluate knowledge, attitudes, and prevention measures of Lebanese dentists towards COVID-19 and determinants of high level of knowledge and prevention practices. METHODS: A cross-sectional study was conducted between May and August 2020 in Lebanon on a random sample of 323 Lebanese dentists. Data were collected through an online survey questionnaire. A multivariate linear regression model was used to evaluate factors associated with COVID-19 knowledge. A multivariate logistic regression was conducted to evaluate the factors associated with high level of prevention measures towards COVID-19. RESULTS: The mean COVID-19 knowledge index was 24.5 over 38 with only 15% achieving high knowledge level. The mean prevention measures index was 11.4 over 16 with only 35% achieving high prevention level. Higher knowledge index was associated with younger age, being employed, and considering dentist's role significant in teaching others about COVID-19. General dental practitioners, dentists living with family members and concerned about their family members to get infected because of their occupational exposure were more likely to report higher level of adopted prevention measures. Higher knowledge was associated with high level of prevention measures. CONCLUSIONS: Given the rapid evolution of information related to COVID-19 pandemic, dentists should be regularly educated through trainings, workshops, and updates of national guidelines for dental healthcare.

Knowledge, attitudes and practices towards people living with HIV/AIDS in Lebanon.

BACKGROUND: Up till today, studies carried in Lebanon have focused more on the prevalence of HIV and behaviors and quality of life of infected individuals, however, none of these studies discussed the degree of stigma towards these populations. Therefore, the aim of this study is to measure the rate of stigma in terms of knowledge, attitude and practice towards patients living with Human Immunodeficiency Virus (HIV) and Acquired Immunodeficiency Syndrome (AIDS) (PLWHA) and examine the factors associated with this stigma. METHODS: A cross-sectional survey, enrolling 862 participants, was carried across the five governorates in Lebanon: Beirut, Mount Lebanon, North, South and Bekaa. The survey was a self-administered questionnaire which covered information about participants' general demographics, their knowledge, attitudes, practices and awareness towards HIV/AIDS in Lebanon., attitudes towards PLWHA, practices related to HIV/AIDS and awareness regarding HIV/AIDS situation in Lebanon. RESULTS: The response rate to the survey was 78.36% (862 participants). Being Muslim (Beta = -2.56) or Druze (Beta = -2.64) compared to Christians were significantly associated with lower knowledge towards HIV/AIDS, whereas having a secondary (Beta = 2.71) and a university (Beta = 3.04) levels of education compared to illiteracy and higher age (Beta = 0.05) were significantly associated with higher knowledge. Higher knowledge (Beta = 0.66) was significantly associated with better attitude, whereas higher age (Beta = -0.14) and being Muslim compared to Christian (Beta = -3.44) were significantly associated with worse attitude. Better attitude (Beta = 0.02) was significantly associated with better practice, whereas females compared to males (Beta = -0.39), having a secondary level of education compared to illiteracy (Beta = -0.88) and being Muslim compared to Christian (Beta = -0.32) were significantly associated with worse practice. CONCLUSION: Our results stress the need for educational programs, advocacy campaigns and policies to help reduce HIV stigma. This will then help start developing interventions and strategies for a possible reduction in the stigmatization level.

Trends in the consumption of antibiotics in the Lebanese community between 2004 and 2016.

Background Antibiotic resistance has reached an alarming rate globally especially in middle-income countries such as Lebanon. The development of antibiotic resistance is strongly linked to the increased population's injudicious consumption of antibiotics. Objective This study aims to explore the trends of antibiotics consumption in the Lebanese community, between 2004 and 2016, to inform rational use of antibiotics. Setting The study was performed using the Intercontinental Marketing Statistics (IMS) Health Lebanon database Method This is an observational longitudinal study conducted through a review of the IMS database. The annual antibiotics consumption was determined by the Defined Daily Dose (DDD)/1000 inhabitants/day (DID). The trends of antibiotics consumption were then categorized by antibiotic class and spectrum of activity. Main outcome measure The total consumption of antibiotics in Lebanon and the classes of antibiotics used by the community. Results Total community consumption of antibiotics, measured by DDD/1000 inhabitants/day (DID), significantly increased from 18.71 in 2004 to 31.26 in 2016. Penicillin combinations, quinolones, third-generation cephalosporins, tetracyclines, and carbapenems showed significant uptrends, in contrast to first-generation cephalosporins, sulfonamides and diaminopyrimidines, and beta-lactamase resistant penicillins. Broad-spectrum antibiotics showed a marked increase in their consumption from 11.50 DID in 2004 to 22.51 DID in 2016 whereas intermediate-spectrum antibiotics had only a slight increase in their consumption from 7.18 DID in 2004 to 8.51 DID in 2016, and narrow-spectrum antibiotics had a severe decline in their consumption from 0.006 DID in 2004 to 0.0003 DID in 2016. Conclusion There is an alarming increase in antibiotics consumption in Lebanon, particularly broad-spectrum antibiotics. This should be complemented with evidence on the determinants of antibiotic consumption such as prescriber and patient-related factors and drug promotional activities to minimize antibiotics overuse.

Risk of cancer in children exposed to antiretroviral nucleoside analogues in utero: The french experience.

All nucleoside analogues for treating HIV infection, due to their capacity to integrate into and alter human DNA, are experimentally genotoxic to some extent. The long-term oncogenic risk after in utero exposure remains to be determined. Cancer incidence in uninfected children exposed to nucleos(t)ide reverse transcriptase inhibitors (NRTIs) was evaluated, by cross-checking against the National Cancer Registry, in the French perinatal study of children born to HIV+ mothers. Twenty-one cancers were identified in 15,163 children (median age: 9.9 years [interquartile range (IQR): 5.8-14.2]) exposed to at least one NRTI in utero between 1990 and 2014. Five of these children were exposed to zidovudine monotherapy, and 15 to various combinations, seven of which included didanosine. Overall, the total number of cases was not significantly different from that expected for the general population (SIR = 0.8[0.47-1.24]), but the number of cases after didanosine exposure was twice that expected (SIR = 2.5 [1.01-5.19]). Didanosine accounted for only 10% of prescriptions but was associated with one-third of cancers. In multivariate analysis, didanosine exposure was significantly associated with higher risk (HR = 3.0 [0.9-9.8]). This risk was specifically linked to first-trimester exposure (HR = 5.5 [2.1-14.4]). Three cases of pineoblastoma, a very rare cancer, were observed, whereas 0.03 were expected. Two were associated with didanosine exposure. Despite reassuring data overall, there is strong evidence to suggest that didanosine displays transplacental oncogenicity. These findings cannot be extrapolated to other NRTIs, but they highlight the need for comprehensive evaluations of the transplacental genotoxicity of this antiretroviral class. Environ. Mol.

Noncardiac Lebanese hospitalized adult patients' awareness of their coronary artery disease risk factors.

BACKGROUND: Noncommunicable diseases are the leading cause of death in Lebanon, with cardiovascular diseases accounting for almost half of the annual deaths. PURPOSE: We aimed to determine awareness of noncardiac Lebanese hospitalized patients for their coronary artery disease risk factors, their level of adherence to medications or lifestyle modifications, and assess factors associated with awareness. MATERIALS AND METHODS: A cross-sectional study was conducted in 14 hospitals with a total of 382 patients. Levels of awareness were evaluated by the comparison of self-report with measurements and laboratory test results. Healthy behaviors and adherence to treatment were evaluated. Factors associated with better awareness were studied using multivariate regressions, while adherence to treatments and healthy lifestyle were described for the different risk factors and in the Framingham Risk Score categories. RESULTS: Our work revealed a moderate-to-high level of awareness (58.7% for overweight/obesity, 75% for hypertension, 85.7% for diabetes, and 86.4% for dyslipidemia) among patients for most cardiovascular risk factors, but a low-to-moderate level of adherence for some interventions such as physical exercise, weight loss, and smoking cessation. CONCLUSION: The results emphasize on the importance of educational campaigns on healthy habits and screening to improve early diagnosis, increase patients' awareness of their risk factors, and, therefore, optimize primary prevention.

In-utero exposure to nelfinavir-ethyl methyl sulfone.

Ethyl methyl sulfone contained in nelfinavir between 2007 and 2008 accidentally exposed embryos and fetuses to a powerful mutagen. We report data for 101 HIV-uninfected children exposed in utero included in the French prospective national cohort. The incidence of malformation was similar to that in the cohort as a whole with different drug exposures; no children had developed cancer after 9 years of follow-up.

Risk of cancer in children exposed to didanosine in utero.

BACKGROUND: Evaluation of long-term tolerance to antiretroviral exposure during pregnancy is required. An increased risk of cancer has been suggested in children exposed in utero to didanosine. METHODS: Updated evaluation of cancer incidence in uninfected children exposed to nucleos(t)ide reverse transcriptase inhibitors (NRTIs) in the French perinatal study of children born to HIV+ mothers, by cross-checking with the National Cancer Registry. Associations between cancer risk and exposure to NRTIs were evaluated by univariate survival analysis and Cox proportional hazard models. Standardized incidence ratios (SIR) were used for comparison with the general population. RESULTS: A total of 21 cancers were identified in 15 163 children (median age: 9.9 years [interquartile range (IQR): 5.8-14.2]) exposed to at least one NRTI in utero, between 1990 and 2014. Five children were exposed to zidovudine monotherapy, and 16 to various combinations, seven including didanosine. Didanosine accounted for only 10% of prescriptions but was associated with one-third of cancers. In a multivariate analysis, didanosine exposure was significantly associated with higher risk [hazard ratio = 3.0 (0.9-9.8)]. The risk was specifically linked with first-trimester exposure [hazard ratio = 5.5 (2.1-14.4)]. Overall, the total number of cases was not significantly different from that expected for the general population [SIR = 0.8 (0.47-1.24)], but was twice that expected after didanosine exposure [SIR = 2.5 (1.01-5.19)]. CONCLUSION: There are strong arguments to suggest that didanosine displays transplacental oncogenicity. Although not extrapolable to other NRTIs, they stress the need for comprehensive evaluation of the transplacental genotoxicity of this antiretroviral class.

Trends in survival after cancer diagnosis among HIV-infected individuals between 1992 and 2009. Results from the FHDH-ANRS CO4 cohort.

Although the decline in cancer mortality rates with the advent of combination antiretroviral therapy (cART) in HIV-infected individuals can be mostly explained by a decrease in cancers incidence, we looked here if improved survival after cancer diagnosis could also contribute to this decline. Survival trends were analyzed for most frequent cancers in the HIV-infected population followed in the French Hospital Database on HIV: 979 and 2,760 cases of visceral and non-visceral Kaposi's sarcoma (KS), 2,339 and 461 cases of non-Hodgkin lymphoma (NHL) and Hodgkin's lymphoma (HL), 446 lung, 312 liver and 257 anal cancers. Five-year Kaplan-Meier survival rates were estimated for four periods: 1992-1996, 1997-2000, 2001-2004 and 2005-2009. Cox proportional hazard models were used to compare survival across the periods, after adjustment for confounding factors. For 2001-2004, survival was compared to the general population after standardization on age and sex. Between the pre-cART (1992-1996) and early-cART (1997-2000) periods, survival improved after KS, NHL, HL and anal cancer and remained stable after lung and liver cancers. During the cART era, 5-year survival improved after visceral and non-visceral KS, NHL, HL and liver cancer, being 83, 92, 65, 87 and 19% in 2005-2009, respectively, and remained stable after lung and anal cancers, being 16 and 65%, respectively. Compared with the general population, survival in HIV-infected individuals in 2001-2004 was poorer for hematological malignancies and similar for solid tumors. For hematological malignancies, survival continues to improve after 2004, suggesting that the gap between the HIV-infected and general populations will close in the future.

Risk of non-AIDS-defining cancers among HIV-1-infected individuals in France between 1997 and 2009: results from a French cohort.

OBJECTIVES: Improved survival among HIV-infected individuals after the advent of combination antiretroviral therapy (cART) had drawn attention on non-AIDS-defining cancers. We evaluated the incidence and risk trends of lung cancer, Hodgkin's lymphoma, liver and anal cancers, focusing on patients with CD4 cell recovery and age at diagnosis, by comparison with the general population. DESIGN: Cohort study. METHODS: Standardized incidence rates were calculated in the HIV-infected individuals followed in the FHDH and the general population in France in 1997-2000, 2001-2004, and 2005-2009. We estimated standardized incidence ratios for each period and for patients with CD4 cell count at least 500 cells/µl for at least 2 years on cART. RESULTS: Among the 84,504 HIV-infected individuals, the risk of lung and anal cancers fell during the cART era, whereas that of Hodgkin's lymphoma and liver cancer remained stable. In 2005-2009, the standardized incidence ratios for lung cancer, Hodgkin's lymphoma, liver and anal cancers were, respectively, 2.8 [95% confidence interval (CI) 2.5-3.1], 26.5 (95% CI 23.2-30.1), 10.9 (95% CI 9.6-12.3) and 79.3 (95% CI 69.5-90.1). Among patients with CD4 cell recovery on cART, the risk was close to that of the general population for lung cancer, nine-fold higher for Hodgkin's lymphoma, and 2.4-fold higher for liver cancer. Age at diagnosis was significantly younger among HIV-infected individuals for lung cancer (-3.3 years), Hodgkin's lymphoma (-1 year) and liver cancer (-10.1 years). CONCLUSION: HIV-infected patients were at a higher risk for the four cancers over 1997-2009. CD4 cell recovery appears to control the excess risk of lung cancer. For liver cancer and Hodgkin's lymphoma, our results suggest that CD4 should never drop below 500/µl 500 cells/µl to avoid the excess risk.

Risk of AIDS-defining cancers among HIV-1-infected patients in France between 1992 and 2009: results from the FHDH-ANRS CO4 cohort.

BACKGROUND: We examined trends in the incidence of the 3 AIDS-defining cancers (ADCs; Kaposi sarcoma [KS], non-Hodgkin lymphoma [NHL], and cervical cancer) among human immunodeficiency virus (HIV)-infected patients relative to the general population between 1992 and 2009 in France, focusing on age at ADC diagnosis and on patients with controlled viral load and restored immunity on combination antiretroviral therapy (cART). METHODS: Age- and sex-standardized incidence rates were estimated in patients enrolled in the French hospital database on HIV, and in the general population in France during 4 calendar periods (1992-1996, 1997-2000, 2001-2004, and 2005-2009). Standardized incidence ratios (SIRs) were calculated for all periods and separately for patients on cART, with CD4 counts ≥500 cells/µL for at least 2 years and viral load ≤500 copies/mL. RESULTS: Although the incidence of ADCs fell significantly across the calendar periods, the risk remained constantly higher in HIV-infected patients than in the general population. In patients with restored immunity, the relative risk remained significantly elevated for KS (SIR = 35.4; 95% confidence interval [CI], 18.3-61.9), and was similar to that of the general population for NHL (SIR = 1.0; 95% CI, .4-1.8). ADCs were diagnosed at a younger age in HIV-infected patients, with a particularly marked difference for NHL (-11.3 years, P < .0001). CONCLUSIONS: The incidence of all ADCs continued to fall, including cervical cancer, in the cART period, but the risk remained higher than in the general population in 2005-2009. In patients with stably restored immunity, KS remained significantly more frequent than in the general population.
