Objectives: Combination neonatal prophylaxis (CNP) is recommended in high‐risk situations for the prevention of mother‐to‐child HIV transmission, although data on its safety are limited. The aim of the study was to identify whether neonatal prophylaxis (NP) type is associated with the risk of severe anaemia or neutropaenia. Methods: An individual patient data meta‐analysis was conducted within six European cohorts, in infants at high risk for acquiring HIV infection. Adjusted logistic regression models were used to assess the risk of National Institute of Allergy and Infectious Diseases, Division of AIDS (DAIDS) grade 3–4 anaemia/neutropaenia at ages 0–6 months. Mixture models of haemoglobin (Hb) level and log10‐transformed neutrophil count (NC) were used to explore associations with NP type at ages 0–18 months. Results: Of 1836 infants, 25% were preterm, 1149 (63%) had antenatal combination antiretroviral therapy (cART) exposure and 395 (22%) received NP (125 received CNP with three drugs). Overall, 117 (6.7%) infants had grade 3–4 anaemia at age 0–6 months and 140 (9.1%) had grade 3–4 neutropaenia. The presence of grade 3–4 anaemia or neutropaenia was not associated with NP type [adjusted odds ratio (aOR) 1.04 for one‐drug NP and 1.60 for three‐drug NP versus two‐drug NP (P = 0.879 and P = 0.277, respectively) for anaemia; aOR 1.33 for one‐drug NP and 1.98 for three‐drug NP versus two‐drug NP (P = 0.330 and P = 0.113, respectively) for neutropaenia], but was associated with preterm delivery. Overall, 7746 Hb and NC results were available for 1836 infants up to age 18 months; no significant differences in predicted Hb level or NC were apparent by NP type. Conclusions: A small proportion of infants experienced grade 3–4 haematological adverse events; risk of anaemia or netropenia was not associated with type of NP. [ABSTRACT FROM AUTHOR]

Objectives: The aim was to summarize national prevention of mother-to-child transmission (PMTCT) guidelines across Europe and to identify differences between these. Methods: A survey was conducted using a structured questionnaire sent to experts in 25 European countries from January to March 2012, requesting a copy of the national guidelines. Responses were received from 23 countries. Results: Twenty-two (96%) countries supported a policy to recommend antenatal HIV screening for all pregnant women (15: opt-out strategy; 8: opt-in strategy). For HIV-positive women in whom the only indication for antiretroviral therapy (ART) was PMTCT, the recommended gestational age for commencing ART varied from 12 to 28 weeks: initiation before 19 weeks gestation was recommended in guidelines from nine countries; in France, the UK and the Netherlands, there was a wide range, from 14 to 24 weeks, whereas the Swiss and Ukrainian guidelines recommended starting at 24–28 weeks and the German/Austrian and Lithuanian at 28 weeks. Six national guidelines recommended inclusion of Zidovudine in antenatal ART regimens, and seven (37%) allowed continuation of Efavirenz for women conceiving on this drug. According to nine guidelines, zidovudine should always be used intrapartum. Eighteen national guidelines stated that HIV-positive women on successful ART can have a vaginal delivery. Viral load thresholds for vaginal delivery were <1000 copies/ml in 5 countries, <400 copies/ml in 3 and <50 copies/ml in 11 countries. Conclusion: There are important differences across Europe in national PMTCT guidelines, with most variation seen where the evidence-base remains limited. Such differences should be considered when interpreting research and surveillance findings. [ABSTRACT FROM AUTHOR]

Abstract Introduction HER2 mutations occur in 1–3% of lung adenocarcinomas. With increasing use of next-generation sequencing at diagnosis, more patients with HER2 -mutant tumours present for treatment. Few data are available to describe the clinical course and outcomes of these patients when treated with afatinib, a pan-HER inhibitor. Methods We identified patients with metastatic or recurrent HER2 -mutant lung adenocarcinomas treated with afatinib among seven institutions across Europe, Australia, and North America between 2009 and 2017. We determined the partial response rate to afatinib, types of HER2 mutations, duration of response, time on treatment, and survival. Results We collected information on 27 patients with stage IV or recurrent HER2 -mutant lung adenocarcinomas treated with afatinib. Of 23 patients evaluable for response, three partial responses were noted (13%, 95% confidence interval [CI] 4–33%). In addition, 57% of patients (13/23) had stable disease, and 30% (7/23) had progressive disease. We documented partial responses in patients with HER2 exon 20 insertions, including two with YVMA insertion and one with VAG insertion. Two patients with partial responses were previously treated with trastuzumab and pertuzumab. Median duration of response to afatinib was 6 months (range 5–10); median time on treatment was 3 months (range 1–30) and median overall survival from the date of diagnosis of metastatic or recurrent disease was 23 months (95% CI 18–53 months). Conclusions Afatinib is modestly active in patients with HER2 -mutant lung adenocarcinomas, including responses after progression on prior HER2-targeted therapies. However, investigations into the biology of HER2 -mutant lung adenocarcinomas and development of better HER2-directed therapies are warranted. Highlights • The response rate of advanced HER2 -mutant lung cancers treated with afatinib was 13%. • All responses were seen in patients with HER2 exon 20 insertion mutations. • Responses were observed even in patients treated with prior HER2-targeted therapies. • Afatinib led to durable disease control in a subset of patients (up to 30 months). • Afatinib was well tolerated in most patients.

Objectives: The rarity of early diffuse cutaneous systemic sclerosis (dcSSc) makes randomised controlled trials very difficult. We aimed to use an observational approach to compare effectiveness of currently used treatment approaches., Methods: This was a prospective, observational cohort study of early dcSSc (within three years of onset of skin thickening). Clinicians selected one of four protocols for each patient: methotrexate, mycophenolate mofetil (MMF), cyclophosphamide or 'no immunosuppressant'. Patients were assessed three-monthly for up to 24 months. The primary outcome was the change in modified Rodnan skin score (mRSS). Confounding by indication at baseline was accounted for using inverse probability of treatment (IPT) weights. As a secondary outcome, an IPT-weighted Cox model was used to test for differences in survival., Results: Of 326 patients recruited from 50 centres, 65 were prescribed methotrexate, 118 MMF, 87 cyclophosphamide and 56 no immunosuppressant. 276 (84.7%) patients completed 12 and 234 (71.7%) 24 months follow-up (or reached last visit date). There were statistically significant reductions in mRSS at 12 months in all groups: -4.0 (-5.2 to -2.7) units for methotrexate, -4.1 (-5.3 to -2.9) for MMF, -3.3 (-4.9 to -1.7) for cyclophosphamide and -2.2 (-4.0 to -0.3) for no immunosuppressant (p value for between-group differences=0.346). There were no statistically significant differences in survival between protocols before (p=0.389) or after weighting (p=0.440), but survival was poorest in the no immunosuppressant group (84.0%) at 24 months., Conclusions: These findings may support using immunosuppressants for early dcSSc but suggest that overall benefit is modest over 12 months and that better treatments are needed., Trial Registration Number: NCT02339441., Competing Interests: Competing interests: ALH has done consultancy work for Actelion, served on a Data Safety Monitoring Board for Apricus, received research funding and speaker's fees from Actelion, and speaker's fees from GSK.
