Rare diseases, affecting a small percentage of the population, continue to pose significant challenges in diagnosis and treatment. According to the Indian Ministry of Health and Family Welfare, approximately 7,000 rare diseases impact around 8% of the global population. Alarmingly, 75% of those affected are children. While advances in treatment options for certain conditions have emerged over the past two decades, numerous patients still suffer due to misdiagnosis, high treatment costs, and a general lack of awareness.
Misdiagnosis and Delayed Diagnosis: A Major Obstacle
The accurate diagnosis of rare diseases, such as Fields condition, Kuru, Gaucher Disease, and RPI deficiency, is crucial to effective treatment. However, diagnosing these conditions can be a lengthy process involving clinical consultation, extensive testing, and cross-referencing symptoms. The rarity of these diseases, coupled with limited documentation and understanding, leads to widespread misdiagnosis and delayed identification of the disorder. Such delays often result in patients undergoing ineffective treatments that do not address the root cause of their health issues.
Dr. Vinit Banga, Director of Neurology and Head of Neuro-Intervention at Fortis Escorts Hospital in Faridabad, emphasized the severity of misdiagnosis in treating rare diseases. “Misdiagnosis is one of the most critical issues when it comes to identifying rare diseases. It prolongs suffering and places patients on incorrect treatments, which often worsen their conditions,” Dr. Banga said. He added that the absence of specialist expertise and genetic testing makes it even more challenging for patients to receive an accurate diagnosis.
Costly Treatments: A Barrier to Access
Once a rare disease is diagnosed, patients often face additional hurdles in accessing appropriate treatments. Available therapies, including small molecule medications, enzyme replacement therapy, antibody therapy, gene therapy, stem cell therapy, and drug repositioning, can be prohibitively expensive. Many of these treatments require long-term care, specialized drugs, or cutting-edge genetic therapies that are not typically covered by standard health insurance policies.
“Even after diagnosing a rare disease accurately, its treatment remains financially prohibitive. Many rare diseases require specialized drugs or long-term care that is invariably high-priced and not usually compensated for by health insurance,” Dr. Banga noted.
The Urgent Need for Awareness and Action
The challenges faced by patients with rare diseases—misdiagnosis, lack of affordable treatment, and low awareness—are pressing issues that need immediate attention. Awareness and timely intervention can significantly improve the quality of life for individuals suffering from these conditions. As Dr. Banga urges, “It is crucial to remain aware of these conditions and their treatments. Many lives have been lost due to the lack of awareness, misdiagnosis, and the high cost of care. It’s time for a concerted effort to address these challenges.”
In conclusion, while there have been notable strides in the treatment of rare diseases, the journey to better care requires a multi-faceted approach that includes increased awareness, improved diagnostic capabilities, and accessible treatment options for patients worldwide.
