Future of HIV2 and HIV2 + 1 Infected Patients Treated with Antiretrovirals Followed at the Day Hospital HIV Care Unit from 2011 to 2015.

Introduction: HIV2 is endemic in West Africa. In Burkina Faso, its prevalence was estimated at 2%. The aim of this work was to evaluate the follow-up of patients and also to contribute to the availability of data. Methods: We involved 18 years or older. Infection was screened according to the national algorithm. A cross- sectional study from first June 2017 to 31 December 2017 was performed. For each patient, sociodemographic, clinical, biological, therapeutic and evolution data were collected and analyzed. Results: The proportion of patients infected with HIV2 (n = 48; 1.7%) and HIV2 + 1 (n = 67; 2.4%) was 4.3%. The sex rat mean age was 50.3 ± 8.5 years. The combination of 2INTI + LPV/r was the most prescribed (n = 73; 63.5%). The average gain of LTCD4 has evolved from + 236 cells/mm3 in 2011 to + 364 cells/mm3 in 2015. The retention rate at grade 5 was about 70%. Conclusion: The immunological and clinic response of the patients was satisfactory. More than half of the patients remained in the continuum of care after five years of follow-up.

Incidence and Predictors of Imported Cases of COVID-19 in Burkina Faso.

BACKGROUND: To limit the spread of COVID-19 due to imported cases, Burkina Faso has set up quarantine measures for arriving passengers. We aimed to determine the incidence and predictors of imported cases of COVID-19 in Burkina Faso. METHODS: A prospective cohort study was performed using data from passengers arriving at the airport from April 9 to August 31, 2020. The data was extracted from the District Health Information Software 2 (DHIS2) platform. Cox regression was used to identify predictors of imported cases of COVID-19. RESULTS: Among 6,332 travelers who arrived in the study period, 173 imported cases (2.7%) were recorded. The incidence rate was 1.9 cases per 1,000 traveler-days (95%CI: 1.6-2.2 per 1,000). Passengers arriving in April (Adjusted hazard ratio [aHR] = 3.56; 95%CI: 1.62-7.81) and May (aHR = 1.92; 95% CI: 1.18-3.12) were more at risk of being tested positive compared to those arriving in August, as well as, passengers presenting with one symptom (aHR = 3.71; 95% CI: 1.63-8.43) and at least two symptoms (aHR = 10.82; 95% CI: 5.24-22,30) compared to asymptomatic travelers. CONCLUSIONS: The incidence of imported cases was relatively low in Burkina Faso between April and August 2020. The period of travel and the presence of symptoms at arrival predicted the risk of being tested positive to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This is essential in the context of the high circulation of virus variants worldwide and the low local capacity to perform genotyping tests to strengthen the surveillance and screening capacities at the points of entry into the country.

Prison health priorities in Burkina Faso: a cross-sectional study in the two largest detention environments in Burkina Faso.

PURPOSE: The purpose of this paper is to study the factors associated with the occurrence of diseases and beriberi among prisoners incarcerated in the two largest Remand and Correctional Facilities (RCF). DESIGN/METHODOLOGY/APPROACH: This was a cross-sectional descriptive and analytical study carried out from April 20 to May 19, 2017, in the RCFs of Ouagadougou and Bobo-Dioulasso. All prisoners who consulted and those referred to the health center by the health-care team were included in the study. Complaints and diagnosed diseases information were collected using the second version of the International Classification of Primary Care (ICPC-2). The authors used a logistic regression model to perform univariate and multivariate analyses. FINDINGS: Of the 1,004 prisoners from the two RCFs included in the study (32.6%), 966 (96%) were male. The median age was 31.6 years. The distribution of diseases diagnosed using the ICPC-2 showed a predominance of gastrointestinal tract, skin and respiratory tract diseases among 206 (19.3%), 188 (17.6%) and 184 (17.2%) prisoners, respectively. A total of 302 prisoners (30.1%) had clinical beriberi, and 80 prisoners (8%) were underweight. Being incarcerated for more than nine months was independently associated with a high risk of digestive and respiratory diseases as well as beriberi. RESEARCH LIMITATIONS/IMPLICATIONS: This study highlighted higher frequencies of digestive, skin and respiratory complaints and diseases in the two largest detention centers in Burkina Faso. These diseases are variously related to age, penal status and length of incarceration. In addition, underweight and thiamin vitamin deficiency responsible for beriberi are more frequent in adult prisoners, those not attending school, convicted prisoners and those with a length of stay in detention of more than nine months. These concrete results should help define a strategy and priority actions needed to reduce morbidity in prisons. PRACTICAL IMPLICATIONS: The actions should include the intervention of specialists in the field of common diseases in prisons, the improvement of individual hygiene conditions and environment, the improvement of the quality and quantity of the food ration, a strategy to reduce prison overcrowding. Other actions must be planned to allow specific groups such as women and minors to have access to health care that is adapted to them. Beyond the central concern of promoting the rights of prisoners and humanizing prisons, actions to improve the health of prisoners are part of an overall public health approach with its socio-economic and environmental implications. SOCIAL IMPLICATIONS: There is a need for a strong commitment from the State to develop a prison health policy that prioritizes the prevention of communicable and non-communicable diseases that are particularly prevalent in this context, without forgetting mental health and nutrition. This requires a collaboration of stakeholders based on better intersectorial communication, the implementation of a monitoring and evaluation system for the health of prisoners, an enhancement of the status of health-care providers working in prisons and an increase in the funding allocated to the health of prisoners with the mobilization of the necessary funds. ORIGINALITY/VALUE: This study uses a primary health care classification to assess the health of inmates in a prison in Africa. It contributes to the weak evidence around prison health surveillance and health profiling of prisoners in Africa.

Predictors of severe hypoxemia among COVID-19 patients in Burkina Faso (West Africa): Findings from hospital based cross-sectional study.

INTRODUCTION: COVID-19 is one of the world's major health crises. The objective of this study was to determine the predictive factors of severe hypoxemia in patients hospitalized in COVID-19 health facilities in Burkina Faso. PATIENTS AND METHOD: This study was a hospital-based cross-sectional study. The data collected relate to the period of the first wave of the epidemic (March 9 to June 30, 2020). All patients hospitalized for COVID-19 in the requisitioned health facilities of Ouagadougou were included in this study. Predictors of severe hypoxemia were identified using a multivariate logistic regression model. RESULTS: During the study period, 442 patients were included, representing 45.7% of the total number of positive patients in the entire country. The most common co-morbidities were diabetes (55; 12.4%) and arterial hypertension (97; 21.9%). Severe hypoxemia (SpO2 < 90%) was observed in 64 patients (14.5%). Age over 65 years (OR = 8.24; 95% CI: 2.83-24.01) and diabetes (OR = 2.43; 95% CI: 1.17-5.06) were the predictors for occurrence of severe hypoxemia in multivariate analysis. CONCLUSION: The predictive factors of COVID-19 are similar in African and Caucasian populations. The surveillance of COVID-19 in risk groups should be strengthened to reduce their morbidity and mortality.

Severe dengue in adults and children, Ouagadougou (Burkina Faso), West Africa, October 2015-January 2017.

Introduction: Although dengue is the most common arbovirus infection worldwide, studies of severe dengue in Africa are lacking, and risk factors for severe dengue have been insufficiently described. This study was conducted in the context of the 2016 dengue epidemic in Burkina Faso to determine the prevalence of severe dengue, identify factors associated with severe dengue, and perform mapping of dengue cases in the country's capital, Ouagadougou. Methods: This cross-sectional study was conducted from November 2015 to January 2017. Data were collected in 15 public and private health centres, and included sociodemographic, clinical and patient outcome variables. Dengue was diagnosed using SD Bioline Dengue Duo rapid diagnostic tests. Data were analysed using Epi-Info Version 7. Logistic regression was used to identify predictors of severe dengue. P<0.05 was considered significant. Dengue case mapping was performed using Geographic Information System software (ArcGIS). Results: Of the 811 patients who tested positive for dengue, 609 (75%) had early dengue (AgNS1 positive) and 272 (33.5%) had severe dengue. Patient age ranged from 1 to 83 years (median 30.5 years) and 393 (48.3%) were female. Renal failure (13.1%) and severe bleeding (10.6%) were the most common signs of severe dengue. Risk factors for severe dengue included age, male sex, haemoglobin S, diabetes, hypertension, and primary dengue. Dengue cases were more concentrated  in sectors located in the centre of the city and close to the health centres. Conclusion: Dengue is increasingly common in Africa and factors associated with severity should be sought systematically as soon as a patient tests positive. Additional studies are needed to determine if the factors found to be associated with severity can be used to identify patients at risk for dengue-related complications, and to provide early and specialized management to reduce morbidity and mortality related to dengue in Africa.

Case Series of Chronic Inflammatory Rheumatic Disease Patients Infected by Coronavirus Disease 2019 (COVID-19).

Coronavirus disease 2019 (COVID-19) is a viral infection that appeared in December 2019. The risk of infection seems to be increased in chronic inflammatory rheumatic diseases due to both immune disturbances related to the disease and treatment. In this case report, we describe the clinical features of 5 rheumatic immune disease patients with the concomitant presence of COVID-19. Among these patients, 3 had rheumatoid arthritis and 2 had systemic lupus erythematosus. Patients' age ranged between 38 and 63 years. Only one patient (SLE) had a severe subtype of COVID-19. All the patients were cured of COVID-19 and were subsequently discharged.

[Epidemiology of acute renal failure during dengue fever in the city of Ouagadougou]. / Épidémiologie de l'insuffisance rénale aiguë au cours de la dengue dans la ville de Ouagadougou.

AIM: Describe acute renal failure during dengue fever in Ouagadougou, in a context of almost nonexistent african data on the subject. PATIENTS AND METHOD: The study was cross-sectional and descriptive with a retrospective collection of data in 13 health structures. It concerned a period of 16 months. Included were suspected cases of dengue fever following the guidelines of the ministry of health and for whom an ARF was diagnosed. The acute renal failure and its severity were defined according to KDIGO's recommendations. RESULT: Sixty-seven cases (sex ratio 2.7 ; mean age 39.6±16.7 years) of acute renal failure were noted among 316 dengue fever patients, or 21.2%. The mean of serum creatinine on admission was 440.7±504.2 µmol/L. The acute renal failure severity was classified at stage 3 in 29 cases, or 43.3%. The most common etiopathogenic factors were those responsible for renal hypoperfusion in 47 cases, or 70.2%; 14 cases of brown macroscopic hematuria, or 20.9%, were observed. Nine patients, or 13.4%, were taken in conventional acute hemodialysis. Six cases of death, a lethality rate of 9%, were observed. CONCLUSION: The acute renal failure in our dengue fever patients population was very common, severe, and highly lethal. The prognosis should improve with early management. It would be even better to promote primary prevention through effective vector control.

Dengue infection during pregnancy in Burkina Faso: a cross-sectional study.

BACKGROUND: Dengue fever is prevalent in the world; in recent years, several outbreaks occurred in West Africa. It affects pregnant women. We aimed to assess the consequences of dengue fever on pregnant women and their fetuses during dengue epidemic in Burkina Faso. METHODS: We conducted a cross-sectional study from November 1, 2015 to January 31, 2017 in 15 public and private health facilities in Ouagadougou, using secondary data. Immunochromatographic rapid test Duo detecting specific antibodies, immunoglobin M/G and /or dengue non structural antigen1 virus was used to diagnose dengue cases. RESULTS: Out of 399 (48%) women registered during the study period, 25 (6%) were pregnant. The average age of pregnant women was 30 years, with 18 and 45 years as extremes. The main symptoms were fever (92%) and headache (92%). Nine patients (36%) had severe dengue characterized by bleeding (16%), neurological symptoms (16%) and acute respiratory distress (8%). Eight (32%) of the 25 women had early miscarriage and 8 (32%) women gave birth to viable fetuses. Among those with viable babies, 5 (20%) presented post-partum hemorrhage and 3 (12%) presented early delivery. The main fetal complications included 3 cases of acute fetal distress (12%). One case of maternal death (4%) and 4 cases of neonatal mortality (44.5%) were notified. CONCLUSION: Dengue fever occurring during pregnancy increases maternal and neonatal mortality. Its severe complications require specific monitoring of pregnant women until delivery.

Building Laboratory-Based Arbovirus Sentinel Surveillance Capacity During an Ongoing Dengue Outbreak, Burkina Faso, 2017.

In West Africa, identification of nonmalarial acute febrile illness (AFI) etiologic pathogens is challenging, given limited epidemiologic surveillance and laboratory testing, including for AFI caused by arboviruses. Consequently, public health action to prevent, detect, and respond to outbreaks is constrained, as experienced during dengue outbreaks in several African countries. We describe the successful implementation of laboratory-based arbovirus sentinel surveillance during a dengue outbreak in Burkina Faso during fall 2017. We describe implementation, surveillance methods, and associated costs of enhanced surveillance during an outbreak response as an effort to build capacity to better understand the burden of disease caused by arboviruses in Burkina Faso. The system improved on existing routine surveillance through an improved case report form, systematic testing of specimens, and linking patient information with laboratory results through a data management system. Lessons learned will improve arbovirus surveillance in Burkina Faso and will contribute to enhancing global health security in the region. Elements critical to the success of this intervention include responding to a specific and urgent request by the government of Burkina Faso and building on existing systems and infrastructure already supported by CDC's global health security program.

Clinical outcomes and mortality associated factors in patients infected with HIV receiving a presumptive anti-tuberculosis treatment in a tertiary level hospital in Burkina Faso.

INTRODUCTION: Tuberculosis is the leading cause of death among people living with HIV/AIDS (PLHIV) in sub-Saharan Africa. In PLHIV, Smear-Negative Pulmonary Tuberculosis (SNPTB) and Extrapulmonary Tuberculosis (EPTB) are predominant. Presumptive anti-tuberculosis (anti-TB) treatment is often delayed leading to a high mortality rate. OBJECTIVES: To investigate the clinical outcomes of presumptive anti-TB treatment in HIV patients suspected of having TB and to determine the factors associated with patients' death. METHODS: We conducted a retrospective descriptive study from 1 January 2007 to 31 December 2008 in the Department of Internal Medicine of the Hospital Yalgado Ouédraogo on patients infected with HIV who received a presumptive anti-TB treatment. Defining patients with SNPTB or EPTB was based on the 2007 WHO's diagnostic algorithm of SNPTB and EPTB. RESULTS: One hundred and sixteen patients of the 383 (30.2%) HIV patients hospitalized in this period were suspected of having TB. The average CD4 count was 86.1 cells/µl (SD = 42.3). A SNPTB was diagnosed in 67 patients (57.8%) and a EPTB in 49 patients (42.2%). The median length of hospitalization duration was 23.5 days. The average time of initiation of anti-TB treatment after admission was 22 days (SD = 9.2 days). Evolution during the hospital stay was favorable for 65 patients (56.0%), unfavorable for 48 patients (41.4% or 12.5% of all hospitalized patients), and 3 patients (2.6%) were treatment defaulters. In a multivariate analysis, hospitalization duration longer than 15 days and a delay of anti-TB treatment initiation of more than 30 days are independent factors associated with patients' deaths. CONCLUSION: An urgent access to TB-diagnostic tools and a revision of the International algorithm for the diagnosis and treatment of SNPTB and EPTB in the context of HIV could help to reduce the delay of anti-TB treatment initiation and the mortality rate of PLHIV in sub-Saharan Africa.

Characteristics and follow-up of newly managed HIV-infected patients in the national referral center in Ouagadougou, Burkina Faso.

BACKGROUND: In sub-Saharan countries, HIV testing and treatment facilities are available, especially at subsidized rates for the past few years. METHODS: A prospective and descriptive review was conducted at Yalgado Ouédraogo Teaching Hospital Internal Medicine department in Ouagadougou, using personal case report forms, between June 2009 and August 2010 in all newly diagnosed adults with positive HIV antibody. RESULTS: The study participants consisted of 191 patients at a median age of 37 years (range, 18-65 years) and sex ratio (men/women): 0.66. In all, 110 (57.6%) patients were symptomatic. Fourteen patients were lost to follow-up. Of the 177 patients, 144 had CD4 count <350 cells/mm(3) and all have been treated. At the ninth month, weight gain and immune restoration were significant (P < .01); only 79 of the 144 patients had viral load measurement, and 76 of the 79 were undetectable. Mortality rate of treated patients was 6.25%. CONCLUSION: Laboratory tests and highly active antiretroviral therapy make the management of patients easier, but a majority of them still presented late and were still lost to follow-up. Nevertheless, we have excellent treatment success.
