Primodos EWG Report : Hannah Bardell MP Talks

Will the Primodos victims, and the new science evidence, be at the heart of the Government report ?

On 21 February 2018, Hannah Bardell, SNP MP for Livingston, raised concerns about the Primodos hormone pregnancy test drug, and asked important questions to the Health Secretary.

Primodos EWG Report : Emma Reynolds MP Talks

Will all Primodos victims be listened to ?

On 24 October 2018, Emma Reynolds, Labour MP for Wolverhampton North East, asked Health Secretary to guarantee women who took hormone pregnancy test Primodos will have time to tell their stories to review into claims it caused birth defects and miscarriages.

Families, including one in Reynolds’ constituency, must have confidence in the review. Answers long overdue.

Abstract

Background
Oral hormone pregnancy tests (HPTs), such as Primodos, containing ethinylestradiol and high doses of norethisterone, were given to over a million women from 1958 to 1978, when Primodos was withdrawn from the market because of concerns about possible teratogenicity. We aimed to study the association between maternal exposure to oral HPTs and congenital malformations.

Methods

I am fully supportive of this article on the effects of hormone pregnancy tests as it stands. I have no substantive criticism of the content or methods.

Dr David Healy, professor of psychiatry, psychopharmacologist, scientist and author.

We have performed a systematic review and meta-analysis of case-control and cohort studies that included data from pregnant women and were exposed to oral HPTs within the estimated first three months of pregnancy, if compared with a relevant control group. We used random-effects meta-analysis and assessed the quality of each study using the Newcastle–Ottawa Scale for non-randomized studies.

Results
We found 16 case control studies and 10 prospective cohort studies, together including 71 330 women, of whom 4209 were exposed to HPTs.

Exposure to oral HPTs was associated with a 40% increased risk of all congenital malformations: pooled odds ratio (OR) = 1.40 (95% CI 1.18 to 1.66; P<0.0001; I2 = 0%).

Exposure to HPTs was associated with an increased risk of

  • congenital heart malformations: pooled OR = 1.89 (95% CI 1.32 to 2.72; P = 0.0006; I2=0%);
  • nervous system malformations OR = 2.98 (95% CI 1.32 to 6.76; P = 0.0109 I2 = 78%);
  • gastrointestinal malformations, OR = 4.50 (95% CI 0.63 to 32.20; P = 0.13; I2 = 54%);
  • musculoskeletal malformations, OR = 2.24 (95% CI 1.23 to 4.08; P= 0.009; I2 = 0%);
  • the VACTERL syndrome (Vertebral defects, Anal atresia, Cardiovascular anomalies, Tracheoesophageal fistula, Esophageal atresia, Renal anomalies, and Limb defects), OR = 7.47 (95% CI 2.92 to 19.07; P < 0.0001; I2 = 0%).

Conclusions
This systematic review and meta-analysis shows that use of oral HPTs in pregnancy is associated with increased risks of congenital malformations.

Reactions

Prof. Henegan’s systematic analyses of epidemiological studies, is a scientific review which members of the Association for children damaged by HPT’s have waited over 45 years for. The findings are incredible and mirror the congenital abnormalities suffered by our members. It is a scandal that this epidemiological study was not commissioned by the Government Health Authorities and we cannot thank Prof. Heneghan and his colleagues enough, for the comprehensive and utterly compelling review.

Why did Primodos remain on the British market for so long ?

A historical argument for regulatory failure in the case of Primodos and other hormone pregnancy tests

Abstract

The drug Primodos and other hormone pregnancy tests (HPTs) remained on the British market for about a decade after they were first implicated, in 1967, as a possible cause of birth defects.

In November 2017, an expert working group (EWG) set up by the Medicines and Healthcare Products Regulatory Agency (MHRA) concluded against such an association.

However, it was explicitly ‘not within the remit of the EWG to make formal conclusions or recommendations on the historical system or regulatory failures’, a situation that has left many stakeholders dissatisfied.

Placing the question of a teratogenicity to one side, this article takes a more contextual and comparative approach than was possible under the auspices of MHRA. It asks why an unnecessary and possibly even harmful drug was allowed to remain on the British market when a reliable and perfectly safe alternative existed: urine tests for pregnancy.

Based on archival research in several countries, this article builds a historical argument for regulatory failure in the case of HPTs.

It concludes that the independent review which campaigners are calling for would have the potential to not only bring them a form of closure, but would also shed light on pressing issues of more general significance regarding risk, regulation and communication between policy makers, medical experts and patients.
