Objective: to determine the clinical and immunovirological characteristics as well as the acceptance of antiretroviral drugs in this patient population. This is a cohort study of the files of PLHIV (People living with HIV) aged 50 years or more, followed in the Internal Medicine Department of the Point G University Hospital between January 2007 and December 2012. Results: Out of 161 HIV-infected patients in the cohort, 38 were aged 50 years or older, of whom 11 met the criteria and were included. The median age was 55 years, 90.9% of whom were in the [50 - 59 years] age group, with 63.6% being women (sex ratio = 0.57). At admission, 3 patients (27.3%) had prurigo and 2 (18.2%) had oral-pharyngeal candidiasis. At inclusion, 45.5% of patients were classified as WHO stage 2 and one as WHO stage 4. All were on ARVs, including 10 on 1st line HIV-1 and 1 on HIV-2. On triple therapy, the average weight gain was 5.1 kg at D15 and 6.84 kg at M6. However, at M12 there was a weight loss of 1.04 kg. The mean CD4 T cell gain was +102/mm<sup>3</sup> at M6 and +188/mm<sup>3</sup> at 12 months. At D0, mean viral load = 565024.75 copies/mm<sup>3</sup> [99 - 1100000] in 4/11. At M12, two patients had undetectable viral loads. Conclusion: The prevalence of HIV in elderly subjects is certainly underestimated. Thanks to triple antiretroviral therapy, PLHIV are aging with HIV but screening is not systematically proposed during consultations in elderly subjects. It is necessary to reinforce communication about HIV at all ages.展开更多

It is an untreatable disease that is fatal once it has been declared. Worldwide, 59,000 cases of rabies-related deaths are recorded each year. The diagnosis of rabies is clinical, biological, and anatomopathological. The aim was to establish the laboratory confirmation capacity for human rabies in Mali. The patient, a Malian female, aged four years, was bitten by a dog around her house in district sixth of Bamako near national road number six in 2020. The patient visited the doctor after a two-month bite. However, she was neither referred to the health center for an effective therapeutic measure nor vaccination (post-exposure prophylaxis). The patient was presented with psychomotor excitation, hypersalivation, aerophobia, and hydrophobia symptoms and visited a Malian hospital named “Hospital of Mali”. The patient was admitted with a history of animal bites and symptoms of rabies, and the patient was classified as a probable rabies case. The patient was then referred to an infectious disease physician and hospitalized. After referring the patient to the infectious disease physician, the physician sent oral swab and cerebrospinal fluid (CSF) samples to confirm to the Laboratory of Applied Molecular Biology. Human rabies was confirmed (RT-PCR) by the zoonotic unit of the Laboratory of Applied Molecular Biology. Diagnosis and therapy of human rabies without post-exposure management after a dog bites were still challenging. It was possible to confirm the human rabies case in Mali by RT-PCR and qRT-PCR.展开更多

We report the case of a 2-month-old infant with congenital left lower lobe emphysema. A 2-month-old female infant, born at term without incident, was hospitalized for respiratory distress. On a postnatal day 15, respiratory distress occurred. On admission, he weighed 3400 g and was apyretic. He had a polypnea of 58 cycles/min and a oxygen saturation of hemoglobin of 90% on room air. A chest radiograph revealed hyperclarity of the left lung. Chest CT revealed left lower lobe emphysema. He underwent a left lower lobectomy. The postoperative course was uneventful. He was discharged from the hospital 7 days after surgery without sequelae. Physicians should be aware that congenital lobar emphysema can present with respiratory distress in infants. A chest CT scan confirms the diagnosis. Surgical treatment is effective.展开更多

Tuberculosis is the 2<sup>nd</sup> leading cause of death from infectious disease after COVID-19 and the 13<sup>th</sup> leading cause of death worldwide. Objective: To collect cases of tuberculosis in children aged 1 month to 15 years in order to study the epidemio-clinical aspects in the pediatric department of the Mali Hospital during the period 2015-2021. Materials and Methods: This was a descriptive, retrospective study from January 1, 2015, to December 31, 2020, and a prospective study from January 1 to December 31, 2021, among children aged 1 month to 15 years admitted for suspected tuberculosis in the pediatric ward of the Mali Hospital. Results: From January 2015 to December 2021, we collected 69 cases of tuberculosis among 9438 hospitalized children, i.e. a frequency of 0.73%. The average age was 6.16 years with extremes of 3 months and 15 years. The sex ratio was 1.1% in favor of boys. The majority of children were vaccinated against tuberculosis (88.4%). The most frequent symptoms were fever (76.8%) and weight loss (73.9%). The pulmonary form was the most frequent (54.9%). Bacteriological confirmation was done in 43.5% of our children. It was Mycobacterium tuberculosis in all confirmed cases. More than half of our children (65.2%) were treated with first-line anti-tuberculosis drugs for 6 months. We observed a cure in 42.0% of our patients and a case fatality rate of 39.1%. Conclusion: Tuberculosis in children is frequent in Mali Hospital despite good BCG vaccination coverage. Its mortality remains high and is maintained by malnutrition, HIV, and the emergence of resistant strains of bacilli.展开更多

It is a good indicator of the degree of transmissibility. While performing routine qPCR, we observed an unusually short cycle threshold (Ct) value of SARS-CoV-2 for a clinical specimen obtained in Bamako, Mali. This prompted us to sequence the short-cycle SARS-CoV-2 sample to identify potential mutations in the Spike gene (S gene) gene. Methods: Post-infection, Quantitative Reverse Transcription (qRT-PCR) was performed over a defined time course to estimate the Ct of the SARS-CoV-2 specimen collected from the patient. Sanger sequencing was done on the entire fragment of the S gene to identify mutations. Findings: Sanger sequencing revealed mutations in the lineage of interest, designated B.1.525 by Pango, and also known as “Eta” using the nomenclature defined by WHO. This variant was originally found in Nigeria and Italy. The four novel mutations identified in Eta (D228N, Y451N, I1172M, and C1250F) were otherwise observed with a low frequency worldwide. Although the initial Ct was 10 in the case study patient, he did not exhibit severe symptoms of SARS-CoV-2, for example, pneumonia. However, we observed a longer viral clearance period than usual, of 3 weeks. We note that as compared to SARS-CoV-2 samples obtained during the first peaks of SARS-CoV-2 infection in Mali, when the infection was at its peak in March 2020 (Ct = 30.4), circulating strains evaluated at the time the Eta sample was obtained demonstrated a lower mean Ct (Ct = 24). Conclusions: The short cycle threshold associated with this variant, and the temporal association with a decrease in the mean Ct in the region of Bamako, may indicate higher levels of transmissibility due to a circulating variant. This variant is a lineage of interest designated B.1.525 by Pango or Eta by WHO.展开更多
