Irene Baker Gruber v. HHS - DPT, Severe Myoclonic Epilepsy (SME) with significant aggravation (2004)

On January 13, 1995, Michael Gruber and Lana Baker filed a petition for compensation under the National Vaccine Injury Compensation Program on behalf of their daughter, Irene Baker Gruber. Irene was born on July 23, 1991.

She received DPT-containing immunizations on September 18, 1991, and November 20, 1991. Between late November 1991 and January 1992, her parents noticed intermittent eye-fluttering episodes.

On January 16, 1992, Irene received her third DPT vaccination, and Dr. Roach observed eye-fluttering episodes without recognizing them as unusual.

Both parties' experts later agreed that Irene was showing symptoms of Severe Myoclonic Epilepsy (SME) before this vaccination. The morning after the third DPT, Irene began to jerk during a diaper change.

Dr. Royhans suspected a seizure, scheduled an EEG, and noted a "seizure - time related to DPT." Irene experienced further seizures on January 29, February 2, February 13, and March 14, 1992, with increasing frequency and intensity.

EEGs performed were abnormal. On March 22, 1992, she suffered status epilepticus lasting about fifty minutes, requiring intubation after medication-induced apnea.

She developed an acute sensitivity to light, and her seizures continued, including a different type of seizure observed on August 5, 1992. Despite these issues, evaluations in July and August 1992 indicated age-appropriate cognitive, social, behavioral, and neurodevelopmental functioning, though fine/gross motor skills were equivalent to a ten-month-old.

By October 1992, she was noted to be experiencing three different seizure types. On March 11, 1996, Irene was hospitalized for status epilepticus and developed liver failure, requiring transfer for a potential liver transplant.

After her liver enzymes normalized, she remained hospitalized for three months. Her parents reported that she lost all developmental gains, became severely mentally retarded, is now wheelchair-dependent, unable to speak, and fully dependent on them.

At an evidentiary hearing on December 11, 1997, Dr. Tracy Glauser, a treating child neurologist for petitioners, testified that Irene's condition markedly worsened after the January 16, 1992 vaccination, beyond what he would expect from SME, and attributed this to the DPT vaccine.

Dr. Mary Anne Guggenheim, a child neurologist for respondent, testified that Irene's course reflected the natural progression of SME, including the development of additional seizure types, and that her condition was not significantly aggravated by the vaccine.

The Chief Special Master granted entitlement on December 22, 1998, finding that Irene's condition was significantly aggravated by the January 16, 1992 vaccine, applying the Whitecotton III test. The Chief Special Master later issued a damages decision on January 20, 2004.

Respondent filed a motion for review. On May 3, 2004, Judge Bruggink reversed and remanded the entitlement decision.

The court held that the Chief Special Master had applied the significant-aggravation test too broadly by treating any new seizure type within the Table period as sufficient without considering whether it was a manifestation of preexisting SME. The court also held that any claimed sequela, including severe mental retardation and related medical problems, required separate causal findings linking them to the significant aggravation of a Table residual seizure disorder.

The public review opinion therefore left compensation unresolved and returned the case for further proceedings. Petitioner counsel was not named.

Respondent counsel was not named. The Special Master was the Chief Special Master.

No award amount or annuity terms were specified in the public text.
