“My name is Sofia’s father, and I would do anything for my daughter—because I love her more than life itself.”
When doctors finally said the words kidney transplant, there was no discussion, no fear, no pause for thought. For him, the decision was instant. He donated his kidney to his daughter Sofia, not as a heroic act, but as the most natural choice in the world. Because how could a father do anything less for his little princess?
Sofia Opalimova is fighting a rare and merciless disease called atypical hemolytic uremic syndrome—known as aHUS. It is a genetic condition that attacks the kidneys, destroys blood cells, and silently threatens vital organs. It is rare, affecting only a handful of children worldwide, but for Sofia and her family, it is an everyday reality that has stolen years of peace, safety, and childhood.
When Sofia was born, she appeared perfectly healthy. For five months, her parents lived in blissful ignorance of the disease quietly sleeping inside her body. Then, without warning, everything shattered. At just six months old, Sofia suffered a sudden cardiac and respiratory arrest. Her parents watched helplessly as doctors fought to bring their baby back to life.
Dialysis followed. Intensive care followed. Fear became permanent.
For a while, Sofia stabilized. Life seemed to return to something resembling normal. But at four years old, the nightmare returned. Her kidneys failed again. Resuscitation. Hospitalization. Dialysis. This time, recovery never truly came. Each relapse grew worse. Each hospitalization lasted longer. Hope became fragile.
For over two years, Sofia’s family lived in hospitals. In Ukraine, where they are from, treatment options were painfully limited. Doctors could offer only symptomatic and palliative care. Eventually, suspicions turned into a diagnosis that changed everything: atypical HUS. A disease so aggressive that without proper treatment, it leads to organ failure and death.
Barcelona became their only chance.
Doctors at Sant Joan de Déu Hospital agreed to treat Sofia. They agreed to try to save her life. But the cost was devastating—nearly one million złoty. A sum impossible for one family to raise alone. And time was running out.
Then came the transplant.
Sofia’s father gave her his kidney without hesitation. He says it was the simplest decision of his life. But even with the transplant, the fight did not end. Sofia now requires constant maintenance treatment to prevent relapses. Complications continue to follow her fragile body, one of the most frightening being epilepsy.
When doctors recently reduced her medication after signs of improvement, Sofia suffered a severe epileptic seizure. Tests were ordered immediately. Fear returned with full force. Her parents live in constant anxiety, never knowing when the next crisis will come.
And yet, they try to protect Sofia’s childhood.
Despite hospital rooms and medical machines, they celebrate every smile. Every moment she plays. Every laugh feels like a miracle. “When I see her smiling,” her father says, “my heart melts. Those moments keep us alive.”
But the trauma has left scars beyond the physical. Years of illness, procedures, and fear have caused Sofia to withdraw into herself. Doctors suspect signs of autism related to trauma. A psychologist has joined her care team, but language barriers make therapy painfully difficult. Sofia needs someone who can speak to her in her own language, who can help her process the unimaginable weight she carries at just eight years old.
Her mother admits there are moments she feels like she is drowning. Moments when she wishes this were all a nightmare she could wake up from—where Sofia is healthy, sleeping peacefully in her own room. But reality brings her back to hospital walls and endless bills.
Their hospital debt has now exceeded 100,000 euros.
This number keeps Sofia’s parents awake at night. It is not just a financial burden—it is a terrifying obstacle standing between their child and the care she needs to survive.
Still, they fight.
They fight because Sofia is alive. Because she laughs. Because she dreams. Because every small step toward a normal life feels like the greatest gift imaginable.
“I gave my kidney to my daughter,” Sofia’s father says. “But it is you who give us hope.”
They are not asking for miracles. They are asking for help. For solidarity. For compassion. For the chance to keep their daughter alive.
Sofia has endured more than any child ever should. But she is still here. And as long as she is here, her parents will not stop fighting.
They only ask that the world stands with them.
