Congenital hydrocephalus and ligneous conjunctivitis in two children with severe type I plasminogen deficiency: A case report and literature review

Abstract

Type I plasminogen (PLG I) deficiency is a genetic disorder inherited in an autosomal recessive mode and carries high mortality and morbidity. This case report discusses two babies, aged 2 and 3 months, who were diagnosed with ligneous conjunctivitis and congenital hydrocephalus. They had progressive macrocephaly, which led to the insertion of a ventriculoperitoneal shunt. However, there was no significant improvement. During the course of the disease, they underwent genetic testing and were diagnosed with PLG I deficiency. One of the babies underwent ventriculocholecystic shunt insertion as part of palliative care and management, since this disease has poor absorption in the peritoneal cavity. Unfortunately, there was no improvement observed, and he died at 18 months. The other baby received intravenous plasma (10 ml/kg) three times a week, plus using several eye drops daily, with moderate improvement. Promising results are expected with the approved plasminogen, human-tvmh, by the Food and Drug Administration. However, access to the newly approved drug in developing countries is challenging, often hindered by cost or supply issues, necessitating the use of alternative treatments.
