Epidemiological and Evolutionary Profile of HIV-HBV Co-Infected Patients Followed at Ambulatory Treatment Center in Fann Hospital Dakar-Senegal
Bibliographic record
Abstract
CONTEXT: Human immunodeficiency virus (HIV) and Hepatitis B virus (HBV) infections are major global public health problems because of their frequency, complications and probable socio-demographic consequences.Viral hepatitis B is identified as more frequent cause of morbidity and mortality in people living with HIV.The objective of this study was to describe the epidemiological and evolutionary profile of HIV-HBV co-infected patients, treated at CTA/CHNU Fann, in Dakar, Senegal.METHODOLOGY: This is a retrospective, descriptive and analytical study of patients aged at least 18 years, co-infected with HIV-HBV and followed-up at CTA under ART for at least one year from January 2010 to December 2014.RESULTS: The study included 457 patients. 58 of these patients were diagnosed positive, (12.7%) of HIV-HBV prevalence. The average age of patients was 39.62 ± 10.12 years with extremes ranging from 21 to 61 years. The sex ratio was 1.23. (96%) of patients were infected with HIV-1 and those at WHO stages III and IV were (67%). The average CD4 count at baseline was 235 cells/mm3 [3-936]. Plasma HIV viral load average at baseline was 4.1 log copies/ml [3.89-5.12] copies/ml. The average body mass index (BMI) was 21.42 ± 3.82 Kg/m². Fever and degraded general status were respectively (65%) and (60%) followed by hepatomegaly and jaundice. The lethality was 3.45%. Of the 58 patients co-infected with HIV-HBV, 51/58 (87.93%) were under a therapeutic regimen containing Tenofovir/lamivudine or Tenofovir/Emtricitabine and 7 patients under a regimen containing lamivudine. At 48 weeks of treatment a good evolution of the biological parameters was noted: (90%) had a controlled viral load, (91%) a normal transaminase, (79%) a normal serum creatinine. Only 29% had a CD4 cell count <350 cells/mm3.CONCLUSION: The Seroprevalence of viral hepatitis B remains relatively high (12.70%) among PLHIV in Dakar. While active search for hepatitis B has been effective in all PLHIV since 2010, overall management remains a challenge as hepatitis B markers and viral DNA assay are not at the reach of patients.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
