Salivary biochemical parameters in people living with HIV on ART and dental caries: a cross-sectional study in Monastir, Tunisia.

BACKGROUND: Studies regarding salivary biochemical parameters and dental caries in adult people living with HIV/AIDS (PLWHA) are scanty. AIM: To investigate salivary biochemical parameters and dental caries in adult PLWHA who are on antiretroviral therapy (ART) and compare the findings with people negative for HIV infection. METHODS: The study included 50 HIV positive individuals as a test group (TG) and 50 HIV negative individuals as a control group (CG). Dental examination was performed according to WHO guidelines to assess DMFT. Digital panoramic radiographs were taken to detect additional infectious foci. Non-stimulated saliva was collected between 9 and 12 a. m for 5 min to evaluate 18 biochemical parameters and salivary flow rate (SFR). Parametric and non parametric tests were used according to data distribution. The level of significance was set at p < 0.05%. RESULTS: Patients' mean ages and M/F sex ratios for TG and CG were 38.80 ± 9.69 y/o. vs. 37.98 ± 13.47 y/o. and 3.54 vs. 2.33, respectively. Higher means of decayed teeth were recorded in TG, 4.47 ± 3.00 vs. 3.88 ± 2.81 in CG with no significant difference (p = 0.41). Means of filled teeth were significantly lower in TG 2.38 ± 2.16 vs. 4.16 ± 3.35 in CG (p = 0.01), respectively. No statistical significant difference was noted in DMFT indices between the 2 groups (8.04 ± 6.90 vs. 8.52 ± 6.24, p = 0.71). The following salivary parameters were significantly lower in TG compared to CG, respectively: mean SFR 0.44 ± 0.18 ml/min vs. 0.61 ± 0.26 ml/min; median levels of sodium and chlorides, 4 mmol/L and 13.5 mmol/L vs. 9 mmol/L and 19 mmol/L (p < 0.001) and uric acid, 103.50 mmol/L vs. 163 (p = 0.009). However, higher median levels were recorded with calcium, 1.09 mmol/L vs. 0.54 (p < 0.001) and sIgA 23 mg/dl vs. 5 mg/dl (p < 0.001). In TG, a positive correlation was found between DC, potassium, urea, and chlorides (p < 0.05). Salivary renal and hepatic biomarkers were comparable between the two groups. CONCLUSIONS: PLWHA have shown an alteration in some salivary parameters, more decayed teeth and less filled teeth. Preventive measures should be implemented to lower dental caries and enhance accessibility to oral care services. In addition, saliva can be utilized to monitor oral and general health status among PLWHA on ART.

Informing a target product profile for rapid tests to identify HBV-infected pregnant women with high viral loads: a discrete choice experiment with African healthcare workers.

BACKGROUND: Elimination of mother-to-child transmission of hepatitis B virus (HBV) requires infant immunoprophylaxis and antiviral prophylaxis for pregnant women with high viral loads. Since real-time polymerase chain reaction (RT-PCR), a gold standard for assessing antiviral eligibility, is neither accessible nor affordable for women living in low-income and middle-income countries (LMICs), rapid diagnostic tests (RDTs) detecting alternative HBV markers may be needed. To inform future development of the target product profile (TPP) for RDTs to identify highly viremic women, we used a discrete choice experiment (DCE) and elicited preference and trade-off of healthcare workers (HCW) in Africa between the following four attributes of fictional RDTs: price, time-to-result, diagnostic sensitivity, and specificity. METHODS: Through an online questionnaire survey, we asked participants to indicate their preferred test from a set of two RDTs in seven choice tasks with varying levels of the four attributes. We used mixed multinomial logit models to quantify the utility gain or loss generated by each attribute. We attempted to define minimal and optimal criteria for test attributes that can satisfy ≥ 70% and ≥ 90% of HCWs, respectively, as an alternative to RT-PCR. RESULTS: A total of 555 HCWs from 41 African countries participated. Increases in sensitivity and specificity generated significant utility and increases in cost and time-to-result generated significant disutility. The size of the coefficients for the highest attribute levels relative to the reference levels were in the following order: sensitivity (ß = 3.749), cost (ß = -2.550), specificity (ß = 1.134), and time-to-result (ß = -0.284). Doctors cared most about test sensitivity, while public health practitioners cared about cost and midwives about time-to-result. For an RDT with 95% specificity, costing 1 US$, and yielding results in 20 min, the minimally acceptable test sensitivity would be 82.5% and the optimally acceptable sensitivity would be 87.5%. CONCLUSIONS: African HCWs would prefer an RDT with the following order of priority: higher sensitivity, lower cost, higher specificity, and shorter time-to-result. The development and optimization of RDTs that can meet the criteria are urgently needed to scale up the prevention of HBV mother-to-child transmission in LMICs.

Limited sampling strategy for predicting isoniazid exposure in patients with extrapulmonary tuberculosis.

WHAT IS KNOWN AND OBJECTIVE: Limited sampling strategies (LSS), using few sampling times after dosing, have been used to reliably predict the isoniazid area under the 24-hour concentration-time curve (AUC). Experience with isoniazid is very limited, and no LSS has been developed in south-Mediterranean populations. Hence, we aimed to develop an accurate and convenient LSS for predicting isoniazid AUC in Tunisian patients with extrapulmonary tuberculosis. METHODS: Pharmacokinetic profiles consisting of six blood samples each, collected during the 24-hour dosing interval, were obtained from 25 (6 men and 19 women) Tunisian patients with extrapulmonary tuberculosis. The AUC was calculated according to the linear trapezoidal rule. The isoniazid concentrations at each sampling time were correlated by a linear regression analysis with the measured AUC. We analysed all the developed models for their ability to estimate the isoniazid AUC. Error indices including the percentage of Mean Absolute Prediction Error (%MAE) and the percentage of Root Mean Squared Prediction Error (%RMSE) were used to evaluate the predictive performance. The agreement between predicted and measured AUCs was investigated using Bland and Altman and mountain plot analyses. RESULTS AND DISCUSSION: Among the 1-time-point estimations, the C3 -predicted AUC showed the highest correlation with the measured one (r2  = .906, %MAE = 10.45% and %RMSE = 2.69%). For the 2-time-point estimations, the model including the C2 and C6 provided the highest correlation between predicted and measured isoniazid AUC (r2  = .960, %MAE = 8.02% and %RMSE = 1.75%). The C0 /C3 LSS model provided satisfactory correlation and agreement (r2  = .930, %MAE = 10.19% and %RMSE = 2.32%). The best multilinear regression model for predicting the full isoniazid AUC was found to be the combination of 3 time points: C0 , C1 and C6 (r2  = .992, %MAE = 4.06% and %RMSE = 0.80%). The use of a 2-time-point LSS to predict AUC in our population could be sufficient. C2 /C6 combination has shown the best correlation but the use of the C0 /C3 combination could be more practical with an accurate prediction. Therapeutic drug monitoring of isoniazid based on the C3 can be used also in daily clinical practice in view of its reliability and practicality. WHAT IS NEW AND CONCLUSION: The LSS using C0 and C3 is reliable, accurate and practical to estimate the AUC of isoniazid. A 1-time-point LSS including C3 had acceptable correlation coefficient and prediction error indicators could be used alternatively.

Interspecific molecular variation of Tunisian complex Lolium perenne L. and Festuca arundinacea Schreb. based on the internal transcribed spacer locus (ITS).

To establish phylogenetic relationships and estimate the intra and interspecific divergence, the amplification and the sequencing of the internal transcribed spacers of ribosomal DNA (ITS = ITS1 + 5.8S + ITS2) were analyzed in Tunisian complex Lolium-Festuca DNA. These spacer regions have evolved mainly by point mutations. Results revealed a high level of polymorphism within studied species. Significant similarities were observed between these two species and showed the existence of an important phylogenetic relationship. Besides, this molecular approach has revealed two new clusterings, with a homologous ITS gene namely: Bromus hordeaceus and Hordeum murinum subsp. This could be explained by the conservation of an ancestral ITS gene in some fescue plants. Thus, Tunisian tall fescue and perennial ryegrass may derive from Bromus hordeaceus and Hordeum murinum subsp. Considerable morphology and bioclimatic distribution similarities were discovered in ITS sequences within the same species. This study can be of great help to identify suitable accessions that could be used in local fescue and ryegrass improvement program.

Robust analysis of the determinants of healthcare expenditure growth: evidence from panel data for low-, middle- and high-income countries.

This paper examines the determinants of healthcare expenditure for low-, middle- and high-income countries, and it quantifies their influences in order to assess policies for achieving universal health coverage. We elaborate two models, a fixed-effect model and the dynamic panel model, to estimate the factors associated with the total health expenditure growth as well as its major components for 167 countries over the period of 1993-2013. The panel data on total health expenditure per capita and its components were taken from the World Development Indicators. Overall, our results showed that total health expenditure per capita is rising in all countries over time as a result of rising incomes. However, our estimates showed that the income elasticity of health expenditure ranged from 0.75 to 0.96 in the fixed-effect static panel model, while in the dynamic panel model, it was smaller and ranged from 0.16 to 0.47. Our empirical findings indicate that development assistance for health reduced government domestic spending on health but increased total government health spending. Our results also indicate that the trend in health expenditure growth is significantly depending with the country's economic development. In addition, out-of-pocket expenditure is powerfully influenced by a country's capacity to increase general government revenues and social insurance contributions. Knowledge of factors associated to health expenditure might help policy makers to make wise judgments, plan health reforms and allocate resources efficiently.

Measuring health-related quality of life: psychometric evaluation of the Tunisian version of the SF-12 health survey.

BACKGROUND: The 12-item short-form health survey (SF-12) was developed as a shorter alternative to the SF-36 for use in large-scale studies as an applicable instrument for measuring health-related quality of life. The main purpose of this study was to evaluate the psychometric properties of the Tunisian version of the SF-12. METHODS: A stratified representative sample (N = 3,582) of the general Tunisian population aged 18 years and over was interviewed. SF-12 summary scores were derived using the standard US algorithm. Factor analysis was used to confirm the hypothesized component structure of the SF-12 items. Reliability was estimated using internal consistency, and construct validity was investigated with "known groups" validity testing and via convergent and divergent validity. RESULTS: SF-12 summary scores distinguished well, and in the expected manner, between groups of respondents on the basis of gender, age, education and socioeconomic status, thus providing evidence of construct validity. Mean scores in the total sample were 50.11 (SD 8.53) for the physical component summary (PCS) score and 47.96 (SD 9.82) for the mental component summary (MCS) score. The results showed satisfactory internal consistency and acceptable convergent validity for both summary scores. Cronbach's α coefficient for PCS-12 and MCS-12 was 0.73 and 0.72, respectively. Known groups comparison showed that the SF-12 discriminated well between groups of respondents on the basis of gender, age, education and socioeconomic status. In addition, no floor or ceiling effects at baseline were observed. The PCA confirmed the two-factor structure of the SF-12 items. Items belonging to the physical component correlated more strongly with the PCS-12 than those with the MCS-12. Similarly, items belonging to the mental component correlated more strongly with the MCS-12 than those with the PCS-12. CONCLUSION: The findings suggest that the SF-12 appears to be a valid and reliable measure that can be used for measuring of population health status. However, for optimal measurement, modifications to traditional scoring methods for the SF-12 should be considered.

Diffuse Kaposi sarcoma with oral involvement in a person diagnosed with human immunodeficiency virus/acquired immune deficiency syndrome: A case report.

Kaposi's sarcoma is a well-known multifocal vascular tumor initially described by pathologist Moritz Kaposi. This report presents the case of a 38-year-old bisexual male who consulted the infectious diseases department with non-itchy maculopapular and purpuric lesions on the skin with the involvement of the oral mucosa, suggesting a diagnosis of Kaposi's sarcoma. Biological and radiological investigations were performed. The patient was found to be human immunodeficiency virus positive with a viral load of 251.000/mL and a CD4 count of 182/mm3. In addition, secondary syphilis was diagnosed. Histopathological examinations confirmed HHV-8 KS. The patient was treated with Extencilline® and antiretroviral therapy. After 10 months of chemotherapy, a favorable outcome was noted with complete resolution of skin and oral mucosa lesions.

[Determinants of risky sex practices among consultants of a Voluntary HIV counseling and testing Centre]. / Déterminants des pratiques sexuelles à risque chez les consultants d'un Centre de Conseils et de Dépistage Anonyme et Gratuit du VIH

BACKGROUND: Thirty years after the discovery of human immunodeficiency virus (HIV), knowledge and practices must be improved. AIM: Contribute to reducing the risk of virus transmission. METHODS: A study about the determinants of risky practices was conducted among the consultants of the Voluntary HIV Counseling and Testing Centre (VCTC) in Monastir University Hospital. RESULTS: We performed a cross sectional descriptive study with a total of 241 consultants who used the services of the VCTC during the period from January 1, 2008 to December 31, 2011. Data gathering was based on a self-administered questionnaire. Consultant's mean age was 27.4 ± 8 years with a male predominance. Three patients out of four were single and 65% have at least secondary-level education. Knowledge about the risk of HIV infection after an unprotected sex and drug use by injection were reported by 94.3% and 76.7% of the participants respectively. Risky sex practices were adopted by 89.3% of the subjects. At least secondary school level, knowledge of risk factors of contamination and fear of the virus transmission were identified as determinants of safe sexual practices (0,004 ≤ p ≤ 0,032). CONCLUSION: Improving knowledge of populations at risk for HIV is a privileged axis to lead to a reduction of infectious risk in our country.

Quality of Life of People Living with HIV on Antiretroviral Therapy: A Cross-Sectional Study in Monastir, Tunisia.

Introduction: Despite the benefits of an efficient antiretroviral therapy (ART), HIV/AIDS epidemic still represents the most seriousaffection worldwide that negatively impacts people's quality of life (QoL). As no studies exist on QoL in Tunisia, the aim of the present work was i: to assess, based on WHOQOL-HIV BREF tool, the perception of QoL of people living with HIV (PLHIV) receiving ART and ii: to investigate the relationship between socio-demographic features, disease-related variables and QoL domains' mean scores. Methods: This cross-sectional study was conducted at the department of infectious diseases of F. Bourguiba Teaching Hospital in Monastir, Tunisia. One hundred and five participants receiving ART were involved. QoL assessment was based on the WHOQOL-HIV Bref including six domains with 29 items with scores ranged from the lowest (4) to the highest (20). Results were reported as frequencies and means (±SD). The Student's t-test for independent samples and the one-way ANOVA were performed to assess differences in QoL mean scores. Linear regression analysis was used to investigate predictors of QoL. The confidence interval was set at 95%. Results: Clients' mean age was 39.20±10.18 years old with a male to female sex ratio of 3.12. Low mean scores were seen with the environment (12.34±2.90), social relations (12.58±3.94) and psychological domains (12.76±3.31), and moderate mean scores were noted for the physical (14.11±3.52), the spiritual (14.05±3.78) and the level of independence (13.98±3.57) domains. Regression analysis showed that health status and feeling healthy were related to all QoL domains and that profession, marital status and the presence of a confident person were related to environment and spiritual domains. Conclusion: QoL of PLHIV on ART is affected. Concrete measures and strategies should be undertaken by healthcare stakeholders to improve QoL determinants.

Accelerating the prevention, control and elimination of communicable diseases through integration and optimization of the support from Gavi and Global Fund: A vision for the Eastern Mediterranean Region.

Over the years, the Eastern Mediterranean Region (EMR) has faced a funding gap with respect to malaria, tuberculosis (TB), HIV, and vaccine-preventable diseases programmes. In the early 2000s, Gavi, the Vaccine Alliance (Gavi) and the Global Fund against AIDS, TB and Malaria (GFATM) became important financial contributors to these programmes. In 2000-2015, funding support from these two global health initiatives allowed progress. However, from 2015, coverage of interventions plateaued, and the region is now behind on the related Sustainable Development Goal (SDG) targets.

Checklist for studies of HIV drug resistance prevalence or incidence: rationale and recommended use.

HIV drug resistance (HIVDR) is a major challenge to the effectiveness of antiretroviral therapy. Global efforts in addressing HIVDR require clear, transparent, and replicable reporting in HIVDR studies. We describe the rationale and recommended use of a checklist that should be included in reports of HIVDR incidence and prevalence. After preliminary consultations with experts on HIVDR and establishing the need for guidance on HIVDR reporting, we used a sequential, explanatory, mixed methods approach to create the checklist; together with the accompanying articles, the checklist was reviewed by the authors and validated externally. The checklist for studies on HIVDR prevalence or incidence (CEDRIC-HIV) includes 15 recommended items that would enhance transparency and facilitate interpretation, comparability, and replicability of HIVDR studies. CEDRIC-HIV will help authors of HIVDR studies prepare research reports and assist reviewers and editors in assessments of completeness of reporting. The checklist will also facilitate statistical pooling and interpretation of HIVDR data.

Prevalence of comorbid asthma in Tunisian patients with COVID-19: clinical features and outcomes.

INTRODUCTION: The coronavirus disease 2019 (COVID-19) pandemic caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has resulted in around 1 million COVID-19 infection cases and over 29,000 deaths in Tunisia thus far. There is great variability in the prevalence of asthma among patients with COVID-19, but the impact of asthma on patients with COVID-19 is not clear. We sought to describe the clinical features of Tunisian patients with COVID-19 and to compare asthmatic and non-asthmatic patients. METHODOLOGY: This retrospective study included 675 Tunisian patients who were hospitalized with COVID-19. Clinical characteristics were collected from medical records. Bivariate analyses and multivariate regression models were used to assess the associations between asthma and the risk of severe symptoms, including death/recovery. RESULTS: The prevalence of asthma in the sample was 14.5%. The results show that asthmatic patients with COVID-19 have significantly less severe symptoms and better outcomes than non-asthmatic patients. CONCLUSIONS: Asthma was not found to be associated with higher severity or worse prognosis among patients with COVID-19 in Tunisia.

Detection of herpes simplex virus (1 and 2), varicella-zoster virus, cytomegalovirus, human herpesvirus 6 and enterovirus in immunocompetent Tunisian patients with acute neuromeningeal disorder.

Enteroviruses (EVs) and human herpesviruses (HHVs) are involved frequently in acute neurological disorders of viral etiology. This study aimed to investigate the incidence of herpes simplex virus types-1 (HSV-1) and 2 (HSV-2), varicella-zoster virus (VZV), cytomegalovirus (CMV), human herpesvirus 6 (HHV-6) and human enteroviruses (EVs) in cerebrospinal fluid (CSF) samples of Tunisian immunocompetent patients with neuromeningeal disorders. The patients had been hospitalized at the Fattouma Bourguiba University Hospital (Monastir, Tunisia) between September 2007 and June 2009. At least one viral genome was detected in 58 (46%) out of 126 CSF samples collected. Enterovirus was detected in 31 of the positive samples (53.4%), CMV in 20 (34.5%), HSV-1 in 3 (5.2%), HSV-2 in 6 (10.3%), VZV in 4 (6.9%), HHV-6 in 2 (3.4%). More than one viral genome was detected in seven CSF samples, including CMV DNA in six of the samples. The high frequency of enteroviral infections in aseptic meningitis was confirmed. The detection of CMV DNA only suggests a direct role of this virus in the etiology of acute neuromeningeal disorder.

Drug rash with eosinophilia and systemic symptoms (DRESS) probably induced by cefotaxime: a report of two cases.

We report two cases, one of a 52-year-old man and one of a 32-year-old man, who were treated with cefotaxime. On day 23 and day 28 of the treatment, respectively, the patients manifested clinically with fever, pruriginous skin rash, and facial edema. Blood tests showed marked eosinophilia and atypical lymphocytosis for both patients, and hepatic cytolysis only in the second patient. Cefotaxime was discontinued in both patients; the clinico-biological picture improved gradually and completely disappeared approximately 4 weeks later. Six weeks after complete recovery, both patients underwent intradermal testing which was positive to cefotaxime (2 mg/ml) at the 48-hour reading and negative to benzylpenicillin, amoxicillin, and cefazolin at the 20-minute and 48-hour readings. These clinical pictures suggest drug rash with eosinophilia and systemic symptoms (DRESS) induced by cefotaxime. To the best of our knowledge, only one case of cefotaxime-induced DRESS has been reported in the medical literature. Thus, we add two new cases of cefotaxime-induced DRESS and emphasize the usefulness and safety of intradermal testing in establishing the diagnosis.

Trends in Adult and Elderly Vaccination: Focus on Vaccination Practices in Tunisia and Morocco.

Vaccine preventable diseases (VPDs) are a prevailing concern among the adult population, despite availability of vaccines. Unlike pediatric vaccination programs, adult vaccination programs lack the required reach, initiative, and awareness. Clinical studies and real-world data have proven that vaccines effectively reduce the disease burden of VPDs and increase life expectancy. In Tunisia and Morocco, the national immunization program (NIP) focuses more on pediatric vaccination and have limited vaccination programs for adults. However, some vaccination campaigns targeting adults are organized. For example, influenza vaccination campaigns prioritizing at risk adults which includes healthcare professionals, elderly, and patients with comorbidities. Women of childbearing age who have never been vaccinated or whose information is uncertain are recommended to receive tetanus vaccination. Tunisia NIP recommends rubella vaccine mainly for women of childbearing age, while in Morocco, national vaccination campaigns were organized for girls and women (up to 24 years of age) to eliminate rubella. Further, travelers from both countries are recommended to follow all requirements and recommendations in the travel destination. The objective of this manuscript is to provide an overview of the global disease burden of common VPDs including (but not limited to) meningococcal diseases, pneumococcal diseases, hepatitis, and influenza. The review also provides an overview of clinical data and guidelines/recommendations on adult vaccination practices, with special focus on Tunisia and Morocco. Some European and North American countries have concrete recommendations and strategies for adult vaccination to keep the VPDs in check. In Morocco and Tunisia, although, there are sporadic adult vaccination initiatives, the efforts still need upscaling and endorsements to boost vaccination awareness and uptake. There is a need to strengthen strategies in both countries to understand the disease burden and spread awareness. Additional studies are needed to generate economic evidence to support cost-effectiveness of vaccines. Integration of private and public healthcare systems may further improve vaccination uptake in adults.

The evolving challenges confronting adults living with HIV in three North African countries during the COVID-19 crisis: a survey-based study.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has resulted in a huge burden on healthcare systems, especially on programs for chronic illnesses such as HIV. We aimed to assess the challenges confronting adult people living with HIV (PLHIV) in three countries in North Africa during the COVID-19 crisis and their awareness of COVID-19 non-pharmaceutical preventive measures. METHODS: This online survey included PLHIV aged ≥18 y from three countries in North Africa recruited by a snowball sampling technique, who were asked to complete a modified questionnaire originally developed by the University of Antwerp in Belgium, which was then disseminated through social media tools to assess the study outcomes. RESULTS: Out of 369 respondents, 260 (70.5%) were males and 237 (64.2%) were aged 18-39 y. Adherence to COVID-19 preventive measures, wearing facemasks (308 [83.2%]), applying hand-sanitizers (299 [80.8%]) and following cough etiquette (261 [70.5%]), were predominantly reported. Only 48 (13%) were vaccinated against influenza. One hundred and forty-five participants (42%) experienced flu-like symptoms, 29 (20%) were tested for COVID-19, with only one confirmed case identified. Among 344 (93.2%) on antiretroviral therapy (73.8% efavirenz- vs 6.4% dolutegravir-based regimens), 219 (63.7%) attended their scheduled visits, 144 (41.9%) had limited access to care due to lockdown and 29 (8.4%) became less adherent to their antiretroviral therapy. Covariates associated with challenges during access to care were age ≥60 y (OR=6.5; 95% CI 1.8 to 23.2) and receiving second-line HIV treatment such as protease inhibitors (OR=2.7; 95% CI 1.3 to 5.8). CONCLUSION: The pandemic adversely affected PLHIV. New innovative strategies should be implemented to ensure the continuity of HIV services.

COVID-19 vaccine acceptance and associated factors among people living with HIV in the Middle East and North Africa region.

Background: Identifying coronavirus disease 2019 (COVID-19) vaccine acceptance and associated factors among people living with HIV (PLHIV) in the Middle East and North Africa region is important to meet the need for broad-scale vaccination against COVID-19. Objectives: To investigate the COVID-19 vaccine acceptance rate and factors among PLHIV in the Middle East and North Africa region. Method: An online cross-sectional survey was conducted among PLHIV currently living in Egypt, Tunisia and Saudi Arabia between March 2021 and August 2021. Results: Of the 540 respondents, 19.3% reported already being vaccinated against COVID-19 (n = 104), 32.0% responded 'definitely yes' (n = 173), and 13.3% responded 'probably yes' (n = 72) for intention to receive a COVID-19 vaccine, with an overall COVID-19 vaccine acceptance rate of 64.6% among PLHIV in the region. The most significant predictors of COVID-19 vaccine acceptance included feeling less worried about COVID-19 transmission post-vaccination (221.0% higher odds), and believing the disease is vaccine-preventable (160.0% higher odds). Reported barriers to COVID-19 vaccine acceptance include concerns about vaccine effectiveness and belief that HIV medications protect against COVID-19 transmission, living in a rural area and reporting less-frequent engagement with HIV care. Nine out of 10 participants reported that the chances of them getting COVID-19 vaccine would increase if given adequate information and if their doctor recommended it. Conclusion: Findings of the study can help researchers, health officials, and other health system actors understand the predictors and barriers to COVID-19 vaccine acceptance reported by PLHIV. This understanding could inform the future planning of interventions tailored to PLHIV.

[H1N1 influenza vaccines in Tunisia: efficiency and safety]. / Les vaccins anti A(H1N1) en Tunisie : efficacité et tolérance.

OBJECTIVE: We carried out this study in order to evaluate the effectiveness and the safety of the two H1N1 vaccines available in Tunisia: Focetria(®) and Panenza(®). METHODS: It's a prospective epidemiological study including 601 vaccinated subjects. The vaccine effectiveness was based on the occurrence of flu clinical symptoms after vaccination. The safety was based on the occurrence of unexpected events after vaccines administration. The vaccines imputability was established according to Begaud et al. method. RESULTS: The number of subjects vaccinated by Focetria(®) is more important than Panenza(®). The efficiency of vaccines would be 93.6%. Neither the medical statue nor the type of the vaccine used influence the occurrence of a flu episode after vaccination. We recorded 406 adverse effects (32.4%) with a high score of imputability (I3). Focetria(®) adverse effects were more frequent than Panenza(®) ones (p = 0.009). Almost all adverse events disappeared within few days. CONCLUSION: The two vaccines used in Tunisia remain enough efficient to face the influenza (H1N1) pandemia and are well tolerated independently of the demographic and pathological statue of the vaccinated person as well as nature of the vaccine used.
