I must have read the same post. Someone commented (and my pulmonologist confirmed) that it may be have been due to Papillon–Lefèvre syndrome (PLS) is a very rare inherited disorder caused by mutations in the CTSC gene.

It is characterized by:
Thickened, scaly skin on the palms and soles (palmoplantar keratoderma)
Severe early-onset gum disease (periodontitis)
Premature loss of both baby and adult teeth
It usually begins in early childhood and is linked to a deficiency of the enzyme cathepsin C (DPP1).

When taking Brinsupri regular dental checks are imperative, every 3-6 months.
