Introduction: In Burkina Faso, as in most developing countries, limited access to biological tests forces practitioners to resort very often to probabilistic antibiotic therapy. The objective of this study is to determine the extent of this prescription. Patients and Methods: This was a cross-sectional study with retrospective data collection of patients hospitalized in the infectious diseases department in the period from January 1, 2005 to December 31, 2020. The records of patients who received probabilistic antibiotic therapy were included. Results: During the study period, 330 patients had received probabilistic antibiotic therapy. The majority of patients were male (53%), with a sex ratio of 1.12. The mean age of the patients was 33 years ± 14. The age range of 20 to 40 years was the most represented (42%). Fifteen percent (15%) of patients were living with HIV. The majority of patients were from urban areas (56.4%). Forty-nine percent (49%) of the patients worked in the informal sector. Clinically, the reasons for consultation were dominated by fever, alteration of general condition, neurological disorders, digestive disorders, respiratory signs, urinary signs and diffuse pain. The physical examination showed that 48.1% of the patients had meningeal irritation syndrome, 10% had convulsions and 10% had focal signs, trismus was present in 4% of the patients and facial paralysis in 3%. In the digestive system, hepatomegaly was present in 29% of patients and digestive candidiasis in 31%. Respiratory examination showed crepitus and fluid effusion syndrome in 26.83% and 20.62% of patients respectively. The presumptive diagnosis was dominated by bacterial meningitis, salmonellosis and bronchopneumonia with banal germs. In terms of treatment, the beta-lactam family of drugs was the most prescribed. They were followed by aminoglycosides and fluoroquinolones. The evolution was marked by the death of 50 patients (15%). Conclusion: The most prescribed molecules belong to

Introduction: Parasitic diseases remain a public health problem in Burkina Faso, as they are in other developing countries. Objective: To describe the epidemiological, clinical and evolutionary characteristics of parasitosis diagnosed in the infectious diseases department of the Yalgado Ouédraogo University Hospital. Patients and Method: This is a descriptive cross-sectional study with retrospective data collection during the period from January 1, 2010 to August 31, 2022. Results: From January 1, 2010 to August 31, 2022, a total of 2829 patients were admitted to the infectious diseases department of the Yalgado Ouédraogo University Hospital in Ouagadougou. Among them, 624 patients suffered from parasitic pathologies, representing a hospital prevalence of 22%. The patients were predominantly male with a sex ratio of 1.1. The average age was 34 years ± 11. Most patients (74.7%) lived in the capital city of Ouagadougou. Ten percent (10%) of the patients with parasitosis were infected with HIV (PLHIV). Out of a total of 624 cases of parasitosis, protozoosis represented 97%, of which 80% were malaria cases. Clinical signs were dominated by neurological signs, digestive signs and dehydration. Comorbidities were dominated by HIV infection, tuberculosis and digestive candidiasis. Under treatment, the evolution was marked by a lethality of 10%. Conclusion: Protozoosis were the most frequently diagnosed. They were dominated by malaria and opportunistic parasitosis during AIDS. These results argue for a revitalization of voluntary HIV testing and careful management of PLHIV.

The use of antimicrobials without microbiological proof is frequent and contributes to the emergence of resistance. The aim was to identify the organisms isolated during laboratory examinations and the type of antimicrobials consumed by patients hospitalized to infectious diseases’ Clinic. This is a cross-sectional and analytical study, carried out from January 1 to December 31, 2017 in the infectious diseases department of Point “G” Teaching Hospital in Mali. All biological specimens from patients during the study period were analyzed. In total, 322 patients benefited from microbiological test, with a mean age of 40.9 ± 12.2 years (range 15 and 74 years) with a sex ratio of 0.93. Only 5.6% of patients were HIV negative. In all participants, a total of 658 microbiological specimen were taken, 224 (34.0%) identified at least one pathogen including bacteria in more than a half of the cases (58.5%). On the report of bacteriological analysis, the most frequently identified organisms were Mycobacterium tuberculosis (42.2%) mainly in sputum;Escherichia coli (24.2%) and Klebsiella pneumoniae (7.8%) commonly in urine and Gardnerella vaginalis (7.0%) exclusively in vaginal secretions. Candida albicans (5/8) and Cryptococcus neoformans (3/8) were the most common fungi while Plasmodium falciparum (96.4%) represented the parasite frequently found in blood. From a therapeutic standpoint, 1143 antimicrobials were prescribed to 322 admitted patients, i.e. 3.55 anti-infectives per patient. Antibiotics (excluding tuberculosis drugs), antiparasitics and antifungals represented respectively 46.2%;18.8% and 15.1% of anti-infectives. Antibiotic therapy was effective in 274 (85.1%) patients and among them, only 76 (27.7%) cases were based on microbiological evidence. Antibiotics are the most widely used antimicrobials in an infectious disease department. Empiric treatments are common but must be minimized by the search for microbiol

HIV infection is a major cause of chronic kidney disease, associated with high morbidity and mortality in sub-Saharan Africa. The objective of this study is to assess the prevalence and risk factors of renal disease at initiation of antiretroviral therapy. This was a descriptive and analytical retrospective study carried out in the infectious and tropical diseases department at Sylvanus Olympio University Hospital. The data have been extracted from the ESOPE software. Kidney disease was defined by a GFR, estimated by MDRD (Modification of Diet in Renal Disease) formula, less than 60 ml/min/1.73 m2. Risk factors associated with kidney disease were assessed using univariate and multivariate analysis. There were 3118 HIV-infected patients included in our study. The median estimated filtration rate was 94.7 ml/min/1.73 m2: 2.9% had an eGFR 2. 1303 had kidney disease (41.8%). Most patients (30.8%) were in the WHO clinical stage 1. The median CD4 count was 165/μL [IQR = 72 - 274/μL];the median hemoglobin level was 10.4 g/dL [IQR = 8.8 - 11.9 g/dL];all patients had thrombocytopenia less than 100.000/mm3;8.5% had leukocytosis greater than 10.000/mm3. Most of patients had HIV1. In the multivariate analysis, age greater than 40 years (p 3 were significantly associated with renal disease. The prevention of kidney disease must go through the identification of its risk factors in the target populations.

Objectives: To identify predictive factors for poor prognosis during cerebral toxoplasmosis at Donka Hospital. Methods: It was a retrospective study of descriptive and analytic type lasting one year six months (18 months) from January 1st, 2016 to June 30th, 2017 which involved patients admitted and hospitalized for cerebral toxoplasmosis in HIV field. Data enter was performed by Epi data 3.1 software and SPSS 21 software for statistical analysis. The threshold of significance was p Results: We observed 87 cases of cerebral toxoplasmosis (CT). The mean age was 38.53 ± 12.16. The clinical signs were mainly infectious syndrome (100%), headache (69.0%), confusion (46.0%) and meningeal syndrome (41.4%). The lethality was 37.9%. Living with a partner (p = 0.007), CD4 at initiation of antiretroviral therapy 3 (p = 0.009), and coma (p = 0.02) were the factors associated with death. Conclusion: This study showed that cerebral toxoplasmosis is associated with very high morbidity and mortality in the infectious diseases department of Donka National Hospital. Living in a relationship, CD4 counts at baseline 3 and coma were independently associated with death. Special attention to these factors associated with infectious resuscitation and primary prevention in patients with a CD4 T lymphocyte count below 200 cells/mm may improve the prognosis of this pathology.

Despite the availability of effective antibacterial drugs, the increasing prevalence of antibiotic-resistant bacteria is primarily attributed to their excessive and inappropriate utilization. Antimicrobial resistance (AMR) represents one of the most concerning global health and development threats [1]. Thereby, the continuous escalation in AMR necessitates urgent advancements in novel antibacterial strategies. The MraY enzyme, which plays a pivotal role in synthesizing bacterial cell wall-composing polysaccharides, holds significant potential as a target for antibacterial agents [2]. However, its conformational dynamics have presented substantial challenges in developing MraY-targeting inhibitors.
