Experience of nevirapine use in a London cohort of HIV‐infected pregnant women
Bibliographic record
Abstract
OBJECTIVE: To describe the experience of four London HIV centres prescribing nevirapine (NVP) to HIV-1 infected pregnant women with respect to immunological and virological response, tolerability and pregnancy outcome. METHODS: We identified all HIV-1-infected women who received NVP as part of a triple antiretroviral regimen during pregnancy between January 1997 and September 1999. Laboratory results, clinical events, side-effects and pregnancy outcome were abstracted using a standardized proforma from the medical records. RESULTS: Forty-six women were identified, 85% of whom were black African. At initiation of NVP, the median age was 29 years and the median baseline CD4 cell count and viral load were 242 cells/microL and 4.15 log10 copies/mL, respectively. Thirty-two out of 36 women who had a plasma sample obtained at, or just prior to, delivery had an undetectable viral load (< 50 to < 400 copies/mL). Adverse events that were definitely attributed to NVP included a generalized rash (n = 2) and hepatitis (n = 2). Obstetric complications occurred in nine women (19.5%), which was not statistically different (P = 0.36) from that found in a historical (1990-96) control group 7/51 (14%). The rate of preterm delivery (13%) was similar to that previously reported in HIV-1 infected pregnant women (18%). CONCLUSIONS: NVP (as part of highly active antiretroviral therapy) reduced plasma viraemia to below the limit of detection in 89% of women. It was generally well tolerated and clinical and laboratory adverse events were infrequent. There was no evidence of an increase in obstetric complications including preterm delivery during the second and third trimesters of pregnancy.

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.
