A 23-month-old girl named Paola, who suffers from indolent systemic mastocytosis, has experienced significant relief following a new medical treatment at Necker Hospital in Paris.
Her 35-year-old mother, Mélanie, confirmed that the toddler's skin is less swollen and her bright red patches have nearly disappeared after previous hospital treatments had failed to ease her intense pain.
Paola, who turns two at the end of September, suffers from severe flare-ups caused by her condition. Her mother explained that the child frequently wakes up crying in agony from what she describes as a sensation of fire inside her body, leading the toddler to scratch her scalp and skin until she bleeds.
Indolent systemic mastocytosis is a rare immunological disorder marked by an excess accumulation of mast cells in bodily tissues. When triggered, these immune cells release chemical mediators such as histamine, causing severe skin reactions, internal inflammation, and systemic discomfort.
Emergency admission to Necker Hospital
Following a severe crisis over the summer in which Paola developed swollen bumps and deep red lesions across her body, Mélanie reached out to Necker Hospital by email. The pediatric institution initially prescribed cortisone, but when Paola's symptoms showed no improvement, her mother contacted the team again.
Within days, hospital staff called the family directly and instructed them to bring Paola to Paris for immediate hospitalization on a Friday at 2:00 pm. Mélanie recalled the emotional toll of leaving her 10-year-old daughter, Lola, behind for the trip, noting that both cried when parting, though she remained determined to find relief for Paola.
Necker Hospital, officially known as Necker-Enfants Malades Hospital, is a renowned pediatric teaching hospital in Paris and one of the oldest specialized children's medical centers in the world.
Specialist diagnosis and bone marrow involvement
Upon arriving at Necker Hospital, the family consulted with a professor specializing in mast cell disorders, who spent nearly an hour and a half explaining the full details of Paola's condition to her parents.
The specialist informed the family that Paola represents a rare case of the disease because her bone marrow is affected, a complication that makes managing her symptoms far more challenging.
To control the severe itching, doctors increased her dosage of antihistamines, describing the move as one of the final therapeutic steps available before considering stronger medical options.
The medical team explicitly sought to avoid placing the child on mild chemotherapy due to the significant risk of heavy adverse side effects. Instead, doctors chose a progressive approach aimed at treating the symptoms as effectively and safely as possible.
Compounded medications and daily routine
Paola currently takes approximately ten medications each day to control her condition. Most of these remedies are custom compounded preparations, as standard commercial drugs cause inflammatory reactions in her body.
The custom medications are manufactured by a specialized laboratory and delivered through the Lafayette Pharmacy in Cahors, a town in southwestern France where the family resides.
While the new medical protocol has brought noticeable relief in the days following her hospital stay, her mother remains cautious about the long-term outlook. Mélanie noted that minor events like a cold or a growing tooth can trigger an immediate flare-up, leaving Paola's back boiling hot, her skin bright red, and the toddler sleepless and agitated.
Impact on family life and support services
The relentless nature of the disease has placed immense strain on the household, with daily life organized entirely around Paola's medication schedules, customized meals, and carefully planned outings.
Mélanie expressed deep concern for her 10-year-old daughter Lola, explaining that the older girl had virtually no summer vacation and is unable to enjoy a normal childhood because Paola must remain indoors throughout the day.
To give Lola relief, Mélanie contacted the Coordination Support Device, a French public health framework that provides home support services. Two care workers now visit for four hours a week to allow Lola to engage in activities she enjoys outside the home.
However, Mélanie stated that no such relief services exist for herself, leaving her exhausted from the continuous physical and emotional demands of caring for a chronically ill child.
Awareness association and upcoming checks
In response to her family's struggle, Mélanie established a non-profit association called La voix de la mastocytose, translated as The Voice of Mastocytosis, to raise public awareness about the rare disorder.
She plans to launch public awareness initiatives around International Mast Cell Disease Day, an annual global event observed on October 20.
On October 19, the day prior to the awareness event, Paola is scheduled to return to Paris for follow-up medical evaluations at Necker Hospital.
Mélanie shared that she feels immense pride when looking at her daughter, even though dealing with public stares and societal perceptions remains a daily struggle for the family.
