Effect of highly active antiretroviral therapy (HAART) on the natural history of ocular manifestations in HIV-infected children

PURPOSE

To determine the effect of highly active antiretroviral therapy (HAART) on the natural history of ocular manifestations in HIV-infected children.

METHODS

All of the HIV-infected children attending the Institute of Pediatrics, University of Milan, Milan, Italy, between 1982 and 2004 were studied. Every 3 months, they were physically examined and underwent indirect fundoscopy conducted by an experienced ophthalmologist; if diagnosed as having eye disease, they were evaluated by the ophthalmologist every week while on specific therapy and monthly thereafter. The clinical and laboratory findings before and after the introduction of HAART were compared.

RESULTS

The cohort consisted of 117 HIV-infected children (61 males), with a follow-up ranging from 0.09 to 22.31 years (median, 16.33 years). A total of nine cases of ocular involvement (7.7%) were diagnosed between 1983 and 1994, before the introduction of HAART. All nine children died 4-24 months (median, 15 months) after the diagnosis of ophthalmic disease. No case of ocular involvement was observed after the introduction of HAART (P=0.011 vs. before HAART).

CONCLUSION

The introduction of HAART has had a significant impact on the natural history of ocular manifestations in HIV-infected children, thus suggesting that a reduction in the frequency of ophthalmologic follow-up should be considered for HAART-treated HIV-infected children with immune reconstitution and no visual symptom.

Bilateral nuclear cataracts as the first neonatal sign of Fanconi-Bickel syndrome

A patient with early bilateral nuclear cataracts and subsequent diagnosis of Fanconi-Bickel syndrome is described. Despite impaired galactose and glucose metabolism, cataracts have been reported in only few cases with this disorder. We conclude that Fanconi-Bickel syndrome should be considered in the differential diagnosis of neonatal cataracts. The pathogenesis of this complication has not been fully elucidated.

Spherophakia associated with molybdenum cofactor deficiency

Molybdenum cofactor deficiency is an autosomal recessive disorder characterized by lack of activity of the enzymes sulfite oxidase, aldehyde oxidase, and xanthine dehydrogenase or oxidase. The clinical manifestations are indistinguishable from those of isolated sulfite oxidase deficiency: craniofacial alterations, intractable neonatal convulsions, very severe mental retardation, lens dislocation, and death in the first decade of life. Lens dislocation is found in nearly all patients after neonatal age. In the present case it developed late (at the age of 8 years) and was preceded by bilateral spherophakia. We hypothesize that an abnormal relaxation of the zonular fibers is the cause of spherophakia in this disease; this causes lens dislocation eventually, after days, months, or years.

[Clinical improvement induced by chemotherapy and social rehabilitation in a preterminal case of brain stem neoplasm: the objective and instrumental aspects]

A sixteen-years-old boy with a brain-stem neoplasia inducing coma was treated with chemotherapeutic agents. It resulted in dramatic clinical and instrumental improvement; radiologic findings were evaluated, showing decreasing dimension of intracranial mass. Brain-stem auditory evoked potentials were highly sensitive. We think that chemotherapy can be considered among the options a physician can offer to such a patient explaining informed consensus.
