Proximal oesophageal strictures in a child with HIV disease

The patient and her twin brother were born preterm by caesarean section. Her birth weight was 2 100 g. She had perinatal exposure to HIV, and was therefore bottle-fed with term formula milk.She remained well until the age of 11 months when, weighing 6 880 g, she required hospital admission for a right upper lobe pneumonia, which responded well to oral amoxicillin. No causative organism was isolated. There was no evidence of active tuberculous infection on gastric washings or Mantoux test
