ObjectivesTo determine whether antenatal betamethasone prior to elective term caesarean section (CS) affects long term behavioural, cognitive or developmental outcome, and whether the risk of asthma or atopic disease is reduced.DesignA questionnaire based follow-up of a multicentre randomised controlled trial (Antenatal Steroids for Term Elective Caesarean Section, BMJ 2005).SettingFour UK study centres from the original trial.Participants862 participants from the four largest recruiting centres, 92% of the original study. 824 (96%) were traced and 799 (93%) were successfully contacted. Fifty-one percent (407/799) completed and returned the questionnaire. The children were aged 8–15 years (median 12.2 years, 52% girls). 386 gave consent to contact schools with 352 (91%) reports received.Main outcome measuresQuestionnaires including a strengths and difficulties questionnaire, International Study of Asthma and Allergies in Childhood, general health and school performance.ResultsThere were no significant differences between children whose mothers received betamethasone and controls for the mean total strengths and difficulties questionnaire scores and subscores for hyperactivity, emotional symptoms, prosocial behaviour, conduct or peer problems. 25 (12%) children whose mothers received betamethasone had reported learning difficulties compared with 27 (14%) control children. The proportion of children who achieved standard assessment tests KS2 exams level 4 or above for mathematics, English or science was similar as were the rates of ever reported wheeze (30% vs 30%), asthma (24% vs 21%), eczema (34% vs 37%) and hay fever (25% vs 27%).ConclusionsAntenatal betamethasone did not result in any adverse outcomes or reduction in asthma or atopy. It should be considered for elective CS at 37–38 weeks of gestation.Trial registration:Original trial was preregistration, the trial publication is BMJ. 2005 Sep 24;331(7518):662.

Objective. To evaluate the efficacy and tolerability of prolonged administration of quinapril, a long-acting angiotensin-converting enzyme inhibitor, in the management of the peripheral vascular manifestations of limited cutaneous systemic sclerosis (lcSSc) and in the prevention of the progression of visceral organ involvement in the disease.Methods. This was a multicenter, randomized, double-blind, placebo-controlled study evaluating quinapril 80 mg/day, or the maximum tolerated dosage, in 210 patients with lcSSc or with Raynaud's phenomenon (RP) and the presence of SSc-specific antinuclear antibodies. Treatment was for 2-3 years. The primary outcome measure was the number of new ischemic ulcers appearing on the hands; secondary measures were the frequency and severity of RP attacks, skin score, treatments for ischemia, health status (measured by the Short Form 36 instrument), measures of kidney and lung function, and echocardiographic estimates of pulmonary artery pressure. An intent-to-treat analysis was used.Results. Quinapril did not affect the occurrence of digital ulcers or the frequency or severity of RP episodes. It did not alter the treatments that were prescribed for either infected ulcers or severe RP symptoms. There was no apparent effect on the estimated tricuspid gradient. Health status was not affected by quinapril, and one-half of the patients who believed they had benefited from the trial treatment were in the placebo arm. Quinapril was not tolerated by one-fifth of the patients, with dry cough being the most frequent side effect.Conclusion. Administration of quinapril for up to 3 years had no demonstrable effects on the occurrence of upper limb digital ulcers or on other vascular manifestations of lcSSc in this patient population.

Objectives. This study aims to examine the utility of von Willebrand factor (vWF) as a biomarker in lcSSc, in particular the ability of vWF to predict the future development of disease manifestations in this disease.Methods. vWFAg concentrations were measured in the serum of patients with lcSSc at baseline and at 3 years, during the QUINs trial [Prevention of Vascular Damage in Scleroderma with Angiotensin-Converting Enzyme (ACE) Inhibition]. %DLCO, %KCO, %FVC, pulmonary artery pressure (PAP) estimation by echocardiography, Raynaud’s attack frequency, Raynaud’s severity, digital ulcer frequency, urinary protein excretion, estimated glomerular filtration rate (eGFR), modified Rodnan skin score and Medsger disease activity score were also measured at baseline and 3 years.Results. Baseline serum vWF concentrations were related to concurrent Medsger disease activity score, %DLCO, %FVC, urinary protein excretion, eGFR and PAP >30 mmHg. In logistic regression models, baseline serum vWF concentrations were able to predict the future development of elevated PAP by echocardiography (PAP >40 mmHg, P = 0.001).Conclusions. Pulmonary artery hypertension is a life-threatening complication of lcSSc. vWF is a marker of endothelial cell activation. Raised serum concentrations of vWF in lcSSc increase the risk of developing subsequent elevation in PAP. Therefore screening patients with lcSSc for vWF may identify a group at risk of developing PAH. These patients could potentially be targeted with agents that stabilize the endothelium, e.g. statins.

The majority of patients with lcSSc belong to distinctive serologic subsets, potentially with prognostic significance.
