ABSTRACT
Burkina Faso, like other countries, reported a focal interruption of onchocerciasis transmission and was thus placed under post-therapeutic surveillance. However, the country seems to be experiencing a resurgence of the disease according to recent surveys at certain sentinel sites and data from various surveys. The aim of our study is to take stock of the evolution of the current epidemiological situation of onchocerciasis in Burkina Faso. For data collection, in addition to the scientific articles, we have used data from different epidemiological and entomological surveys conducted by the National Program for the Control of Neglected Tropical Diseases (PNLMTN) through its onchocerciasis elimination unit in Burkina Faso. Prior to implementation of the Onchocerciasis Control Program in West Africa (OCP), Burkina Faso had onchocerciasis prevalence between 60% and 80%. In 2002, the maximum prevalence dropped to 15%. However, in 2010 and 2011, epidemiological surveys indicated that some villages in the Comoé River basin had prevalence rate ranging from 0.7% to 71%. Thirteen (13) villages had prevalence rates above the tolerable threshold of 5%. Despite the implementation of the community-directed treatment with ivermectin (CDTI) since 2011, recent surveys show a tendency for a recrudescence of the disease in some sites, yet covered by the TIDC. This suggests that the elimination of onchocerciasis requires the integration of new control strategies. Thus, an essential condition for the elimination of onchocerciasis is the analysis of the situation in each focus in order to define the most cost-effective strategy for permanently interrupting the transmission of the parasite. National onchocerciasis elimination committees put in place will play a key role in determining the best strategy.
Le Burkina Faso, comme d'autres pays, avait signalé une interruption focale de la transmission de l'onchocercose et était ainsi placé sous surveillance post-thérapeutique. Cependant, le pays semble connaître une résurgence de la maladie selon les récentes enquêtes au niveau de certains sites sentinelles et les données de diverses enquêtes. Le but de notre étude est de faire le point sur l'évolution de la situation épidémiologique actuelle de l'onchocercose au Burkina Faso. Pour la collecte des données, nous nous sommes servis, en plus des articles scientifiques, des données des différentes enquêtes épidémiologiques et entomologiques menées par le Programme national de lutte contre les maladies tropicales négligées (PNLMTN) au travers de son unité d'élimination de l'onchocercose au Burkina Faso. Avant la mise en oeuvre du Programme de lutte contre l'onchocercose en Afrique de l'Ouest (Onchocerciasis Control Programme in West Africa), le Burkina Faso enregistrait des prévalences de l'onchocercose comprises entre 60 et 80 %. En 2002, la prévalence maximale a chuté à 15 %. Cependant, en 2010 et 2011, des enquêtes épidémiologiques indiquent que certains villages du bassin de la Comoé avaient des prévalences allant de 0,7 à 71 %. Treize villages avaient des prévalences supérieures au seuil tolérable de 5 %.Malgré la mise en place du traitement à l'ivermectine sous directives communautaires (TIDC) depuis 2011, les récentes enquêtes montrent une tendance à la recrudescence de la maladie dans certains sites, pourtant couverts par le TIDC. Cela suggère que l'élimination de l'onchocercose nécessite l'intégration de nouvelles stratégies de lutte. Ainsi, une condition essentielle pour l'élimination de l'onchocercose est l'analyse de la situation dans chaque foyer afin de définir la stratégie la plus rentable pour interrompre de manière permanente la transmission du parasite. Les comités nationaux d'élimination de l'onchocercose mis en place joueront un rôle clé dans la détermination de la meilleure stratégie.
ABSTRACT
The present investigation aimed to assess the prevalence of genotypes of C. albicans in Ouagadougou and to analyze the relationship between the genetic diversity and antifungal susceptibility. Ninety-six clinical strains are included. They were diagnosed as C. albicans using germ tube test, chlamydospore formation, and Api-Candida test. Genotyping was performed using PCR targeting 25S rDNA. Antifungal susceptibilities were tested based on the disk diffusion method. The genotypes A (85.4%) was predominant followed by genotypes B (10.4%) and C (4.2%). The highest resistance rate with genotype A was obtained with fluconazole (74.4%). A resistance to amphotericin B was observed with genotypes A (29.3%) and B (30%).

A cross-sectional study was conducted in Bobo-Dioulasso, Burkina Faso, to identify the yeast diversity associated with the manufacture of dolo, a traditional fermented beverage of Burkina Faso. From sixty specimens spread onto chromogenic medium plates, sixty-two strains were isolated then identified using MALDI-TOF analysis. Seven yeast species were identified, Saccharomyces cerevisiae (39%) followed by Pichia manshurica (18%) being the most frequent. Forty-three percent of the samples contained Candida species, notably Candida albicans. In conclusion, the combined use of a chromogenic medium and MALDI-TOF analysis reveals a higher diversity in yeast species present in the dolo than previously thought.

INTRODUCTION: In recent years, the infection Candida albicans infection worldwide has risen, and the incidence of resistance to traditional antifungal therapies is also increasing. The aim of this study was to evaluate in vitro susceptibility of C. albicans clinical isolates to eight antifungal agents in Ouagadougou. MATERIALS AND METHODS: A cross-sectional study was conducted from January 2013 to December 2015 at Yalgado Ouédraogo University Teaching Hospital. Two hundred seven strains have been isolated from 347 symptomatic patients received in different clinical services. Samples were cultured on Sabouraud Dextrose Agar supplemented with Cloramphenicol. Isolates were diagnosed as C. albicans using germ tube test, chlamydospore formation on Corn Meal Agar, and Api-Candida test (Biomérieux). Antifungal susceptibility testing was performed by disk diffusion method and isolates classified as susceptible, susceptible dose-dependent and resistant. RESULTS: Three hundred forty-seven (347) patients are included in this study. Two hundred and six (206) out of 347 collected samples (59.36%) were found positive for C. albicans. The strains were mostly isolated from vulvovaginal (49%) and oral infections (40.3%). The highest resistance rates of azoles were obtained with fluconazole (66.5%), itraconazole (52.3%) and ketoconazole (22.9%) when all clinical isolates were included. The resistance rates of fluconazole, itraconazole and ketoconazole remain highest for vulvovaginal and oral isolates. The rate of resistance to the polyene amphotericin B was 32.0% for all clinical isolates and was 56.4% for vulvovaginal strains. Resistance rate to nystatin was 6.3% for all clinical isolates. Cross-resistance analysis with data of all clinical strains revealed that the incidence of resistance to ketoconazole and itraconazole in fluconazole-resistant isolates was significantly higher than recorded for fluconazole-susceptible isolates. CONCLUSION: In vitro C. albicans antifungal susceptibility test in this study showed relatively high resistance to commonly and widely used azoles (fluconazole, ketoconazole). Most C. albicans clinical isolates were susceptible to nystatin.

AIM: Our study aimed to analyze the epidemiological aspects of cutaneous mycosis in people living with human immunodeficiency virus (PLHIV). MATERIALS AND METHODS: This is a descriptive study of 382 patients living with HIV. Following an investigation into the risk factors, mycological samples have been performed. Each sample underwent direct examination and cultivation for the identification of fungal species. The Blastese test is used for the identification of Candida albicans. RESULTS: One hundred and six (106) of the 382 people living with human immunodeficiency virus undergo a mycological collection of which 76 gave a positive result. The overall prevalence of cutaneous mycosis was 19.9 %. It was significantly higher in women and in patients who had a CD4 count ≤500/mm3. C. albicans and Trichophyton rubrum were the most isolated species with 22.4 and 19.8 % of all fungal species isolated, respectively. CONCLUSION: Cutaneous mycoses are common among people living with human immunodeficiency virus and whose CD4 count ≤ 500/mm(3).

Mycetoma is a bacteriological or fungal infectious disease affecting the skin and/or soft tissues, which can be complicated by bone involvement. The most common feature is a tumor of the foot, but extrapodal localizations have been described. We report one case of a 47-year-old man who presented with tumefaction of a leg with multiple skin fistulae. Histopathological examination permitted to confirm the diagnosis of actinomycetoma and TDM showed the degree of bone and soft tissues involvement. Our case was characterized by the very inflammatory aspect of the tumor, its localization to the leg without foot involvement, the modest functional signs compared to the importance of radiological bone involvements, the deep destruction of the fibula while the tibia was apparently intact and the good response to treatment. In spite of its characteristic features, diagnosis of mycetoma is still late in our country, often with bone and/or articular spread. Priority may be given to measures for reduction of mycetoma diagnosis lateness.

OBJECTIVE: The fight against fungal infections in prisons is within the overall framework of the fight against these diseases in the general population. To contribute to the fight against these diseases, we conducted this study among inmates of the big prison of Ouagadougou. It aimed to analyze the epidemiological and etiological aspects of superficial fungal infections among prison inmates in Ouagadougou. MATERIALS AND METHODS: It was a matter of an analytical descriptive study (December 2011-April 2012) that examined 212 selected using a stratified sampling detainees. It consisted firstly of a survey on risk factors. Secondly, samples were taken from prisoners with suspicious lesions of superficial mycoses. For each lesion, some fragments were examined directly between slide and coverslip in KOH (10% or 30%). The remaining fragments were cultured on Sabouraud-Chloramphenicol and Sabouraud-Chloramphenicol-Actidione. The media were then incubated at 27°C for 1 month before declaring any negativity. RESULTS: The overall prevalence of superficial fungal infections among prison inmates Ouagadougou was 25.5%. The recent prison inmates (≤24 months) were the most affected (89.8%). Dermatophytes (15.56%) were more isolated than non-dermatophytes (12.26%) Anthropophilic species predominated among dermatophytes: T. mentagrophytes (7.0%), T. rubrum (3.3%), M. langeronii (23%), E. floccosum (1.41%) and T. violaceum (0.94%). M. gypseum (0.47%) was the only land-based species encountered. Non-dermatophytes were Malassezia sp. (11.79%) and Candida sp. (0.47%). Polyparasitism was less represented (7.4% of infected prisoners). Several body sites were mostly infected by one fungal agent. Pityriasis versicolor was the most common fungal infection (37.31%). CONCLUSION: Considering the results, specific control measures are to be taken against the superficial fungal infections in prisons and in the general population.

After widespread use and misuse of antimalarial drugs led to the emergence of resistance, new guidelines for malaria treatment with artemisinine-based combination therapy (ACT) were introduced in Burkina Faso in 2005. To describe the management (drug therapy and other practices) of patients with suspected malaria before their admission to the district hospital of Dô, seven years later. This cross-sectional study was conducted during admission to the district hospital, during the low season for malaria, from December 2010 to May 2011. It included all patients aged 6 months or older diagnosed with suspected malaria according to the criteria of the national malaria control program, excluding those with severe comorbidities. The study included 476 suspected cases, 422 (88.7%) uncomplicated and 54 (11.3%) complicated. They accounted for 7.9% of all admissions. Their mean age was 14.4 years, and 35.3% (n = 168) were younger than 5 years. Only 23 (4.8%) had first consulted in a primary health care facility; 346 (72.7%) had used initial self-medication (or, more precisely in some cases, parental administration of medication without medical consultation). Overall, 435 (91.4%) came directly to the district hospital, 331 (76.1%) of them after self-medication; 10 (2.1%) had first consulted a traditional healer. The practice of self-medication did not differ according to age, gender, or complications (p>0.05). The drugs used for self-medication were mainly antipyretics (94.5%) and antimalarials (16.8%); the latter included ACT (39.6%), quinine (19.0%), and non-recommended antimalarial agents (41.4%). During the malaria low season, the treatment itinerary of suspected malaria cases is marked by equal use of ACT and non-recommended antimalarials for self-medication and minimal use of the primary level of care. A study underway of this management and these itineraries during the epidemic season may provide more data about use of ACT, the last armament against malaria in drug-resistant areas such as Burkina Faso.

OBJECTIVE: To identify Candida species in asymptomatic subjects in Bobo-Dioulasso (Burkina Faso) by the matrix-assisted laser desorption ionization-time of flight mass spectrometry. METHODS: A cross-sectional study was conducted from January to February 2013 in Bobo-Dioulasso to collect fecal and urine specimens from voluntary donors. Fungal strains were isolated on Sabouraud dextrose agar and analyzed using matrix-assisted laser desorption ionisation-time-of-flight mass spectrometry. RESULTS: A total of 135 samples including stools (78.5%, 106/135) and urine (21.5%, 29/135) were analyzed. The results revealed that fecal specimens contained mainly Candida krusei (C. krusei) (42.5%) followed by Candida albicans (29.3%), Candida glabrata (18.0%) and Candida tropicalis (C. tropicalis) (4.7%). C. krusei (34.6%) was also found to be the most frequently identified in urine samples followed by Candida albicans (27.0%), C. tropicalis (15.4%) and Candida parapsilosis. However, uncommon species such as Candida nivariensis, Candida kefyr, Candida norvegensis, Candida parapsilosis, Candida lusitaniae and Candida robusta were also identified from fecal and urines samples. CONCLUSIONS: This study noted the emergence of species such as C. krusei, Candida glabrata, Candida parapsiolosis, C. tropicalis, Candida nivariensis, Candida norvegensis, and others. It is an imperative to take into account the existence of these species in the therapeutic management of patients in Bobo-Dioulasso.
ABSTRACT
The deficit of cellular immunity, as found in HIV infected individuals, may lead to the reactivation of latent Toxoplasma gondii cysts, with as consequence, the occurrence of toxoplasmosis and an eventual vertical transmission of the disease during pregnancy. The present study was designed for determining the occurrence of latent Toxoplasma gondii among HIV-infected pregnant women during the first trimester in Bobo-Dioulasso. Thus, 348 pregnant women aged from 17 to 47 years (average age of 6.64 ± 4.75 yaers) were enrolled. The specific anti-Toxoplasma gondii IgG and IgM antibodies were quantified from whole blood specimens using the high-sensitivity direct agglutination and the enzyme linked fluorescent assays, respectively, the IgG avidity test being used for the dating of the primary infection. The results revealed that the seroprevalence of Toxoplasma gondii latent infection was 34.7%. It was significantly higher in HIV-infected women compared with uninfected ones (68,7%; CI 95%: 43,6%-88,9%) versus (33,1%; CI 95%: 28, 2%-38,3%). In addition, all the occurrences of the high IgG avidity were closely linked with the presence of IgM. These results underlined the need for the clinical follow-up of the maternal HIV diseases including the toxoplasmosis during the pregnancy since; the newborns are still exposed to vertical transmission of Toxoplasma infection in endemic areas like Burkina Faso.

The objectives of this prospective study, conducted from November 2011 to July 2013, in Bobo-Dioulasso were to evaluate seroprevalence of toxoplasma infection and to screen for maternal and congenital toxoplasmosis during pergravidic monitoring. MATERIAL AND METHODS: Techniques of High Sensitivity Direct Agglutination (HSDA) and Enzyme Linked Fluorescent Assay (ELFA) were used for the detection of IgG and IgM toxoplasma respectively. The IgG avidity assay was used for the dating of seroconversion. Screening and monitoring for fetal lesions were echographic. In case of seroconversion, a prenatal treatment with pyrimethamine and sulphonamide was introduced. Systematically and regularly immunoassay surveillance of newborn from cases of recent pergravidic toxoplasmosis was performed until complete and final negativity of serology. RESULTS: In total 301 pregnant women were included. The overall seroprevalence was 31.9%. Three cases of seroconversion (0.9%) including two cases at the 22nd and one at the 41th week of amenorrhea were noted. Series of obstetrical echography have detected no case of fetal Toxoplasma gondii infection and no congenital toxoplasmosis was detected. CONCLUSION: This study underlines the importance of implementation of a legal disposition for screening and routine monitoring of toxoplasmosis during pregnancy. This is due to the low rate (31.9%) of toxoplasma immunity among gestante in Burkina Faso that may lead to pergravidic acute toxoplasmosis or congenital toxoplasmosis whose outcome is often fatal.
Les objectifs de la présente étude prospective conduite de Novembre 2011 à Juillet 2013 à Bobo-Dioulasso ont été d'évaluer la séroprévalence de l'infection toxoplasmique et de dépister une toxoplasmose maternelle et congénitale au cours du suivi pergravidique. MATÉRIEL ET MÉTHODES: Les techniques d'agglutination haute sensibilité (ADHS) et ELFA (enzyme linked fluorescent assay) ont respectivement servi à la détection des IgG et d'IgM anti toxoplasmiques. Le test d'avidité des IgG a servi à la datation de la séroconversion. Le dépistage et le suivi des lésions fÅtales ont été échographiques. En cas de séroconversion, un traitement anténatal associant pyriméthamine et sulfamide a été instauré. Une surveillance immunologique systématique et régulière du nouveau-né issu de cas de séroconversion toxoplasmqiue a été faite jusqu'à négativation complète et définitive de la sérologie. RÉSULTATS: Au total, 301 gestantes ont été incluses. La séroprévalence globale a été de 31,9%. Trois cas de séroconversion (0,9%) dont deux à la 22 ème et un à la 41ème semaine d'aménorrhée ont été notés. Les séries d'échographies obstétricales n'ont dépisté aucun cas d'infection toxoplasmique fÅtale et aucune toxoplasmose congénitale n'a été détectée. CONCLUSION: Cette étude souligne l'intérêt de la mise en place d'une disposition légale de dépistage et de surveillance systématique de la toxoplasmose gestationnelle. Ceci en raison du faible taux (31,9%) de l'immunité toxoplasmique de la gestante au Burkina Faso qui peut conduire à une toxoplasmose aiguë pergravidique voire une toxoplasmose congénitale dont l'issue est parfois fatale.

ABSTRACT
It is a retrospective study in the Service of Dermatology at the University Hospital Center Yalgado Ouédraogo of Ouagadougou (C.H.U.-YO). This study aimed to list the leishmaniasis clinical cases reported in the registers of this department from January 1999 to December 2007. In total, 251 leishmaniasis clinical cases have been reported. The hospital prevalence was 1,1%. Women represented 53% versus 47% men. The average age of patients was 22,78 ans +/- 121. The most frequent clinical forms were those often crusted (40.2%), papulo ulcerative (16.7%) and papulonodular (13.9%). Lesions most often sat on the lower limbs (33%) and thoracic limbs (45%). On the therapeutic level, the first line treatment meglumine antimonite (Glucantime) accounted for only 25.9% of prescriptions.

INTRODUCTION: Mansonella perstans is a genus of filaria that is often asymptomatic or responsible for unspecific symptoms. M. perstans microfilariae are uncommon on cervicovaginal smears. CASE: We report the case of a woman with pruritis and eosinophilia. Microfilariae of M. perstans were observed on both cervicovaginal and blood smears. The patient was successfully treated with a combined single dose of 400 mg of albendazole and ivermectin (150 µg/kg). CONCLUSION: We described here an atypical and rare localization of M. perstans. The routine examination of cervicovaginal smears of women admitted to Bobo-Dioulasso Hospital for screening of cervical neoplasia should allow us to determine the frequency of this parasitosis and propose appropriate treatment.

The purpose of this study is to describe trends in the annual incidence of cutaneous leishmaniasis in Ouagadougou, Burkina from 1999 to 2005. Data recorded at city health care centers were reviewed. A total of 7,444 cases of cutaneous leishmaniasis were observed, with an annual mean incidence of 1,063.3 +/- 270.8 cases. The M/F sex ratio was 0.9. Mean patient age was 22.8 +/- 13.5 years. Patients older than 15 years accounted for 72.5% of the population. The predominant age bracket was 16-30 years (51.80%).A decrease in incidence was observed from March to June and in December. Peak incidence occurred in September and October. Over the 7-year study period, the average incidence rate was 0.1% +/- 0.04. Since this rate does not reflect the real prevalence of the disease, a prospective study is needed.

UNLABELLED: The purpose of this study was to assess the application of national guidelines on the diagnosis and treatment of severe malaria in adults in Burkina Faso. We conducted a retrospective study of medical records of the patients admitted for severe malaria in the emergency service of the regional hospital of Fada N'Gourma in the east of Burkina Faso in the year 2008; 165 records were chosen by simple random sampling. We reported all the severe clinical and biological signs of malaria and its treatment. We compared them with the criteria of severe malaria diagnosis and its treatment according to the national guidelines. The mean age of patients was 38 ± 16.2 and male to female ratio was 0.96. The most frequent period of admissions was between July and October. Fever or recent past of fever was reported in 142 cases (86.1%). According to the two criteria for severe malaria (means existing of at least one of the severe signs associated and positive parasitemia with Falciparum plasmodium), we noted that only 74 cases had at least one of the severe signs (44.8%) which were: anemia (51.3%), cardiovascular collapse (7.9%), jaundice (7.3%), dyspnea (6.7%), impairment of consciousness (5.5%), prostration (5.5%), renal failure (4.8%), hypoglycemia (2.4%), hemorrhage (1.8%) and seizures (1.2%). The biological signs were not systematically searched. Parasitological exam was conducted in 91 cases (55.1%). Only 18 were positive (19.8%). In total, only 18 cases (10.9%) met the guidelines' criteria of severe malaria. The other cases were over-diagnosed; note that the investigation was not complete for 74 of these cases (50.3%). Among the 165 cases, the treatment was appropriate in 146 (88.5%) and 19 cases (11.5%) didn't receive treatment for malaria. CONCLUSION: So much we observed an over diagnosis of severe malaria in adults that we can suggest an under diagnosis of the disease due to the lack of biological investigations.
