Hardikar syndrome

Hardikar syndrome is an extremely rare multisystem disorder first described by Hardikar et al. in 1992. It is characterized by a distinctive combination of obstructive liver disease (typically biliary atresia or other forms of cholestasis), intestinal malrotation, and cardiovascular anomalies, along with genitourinary abnormalities and cleft lip and/or cleft palate. Additional features may include pigmentary retinopathy, hepatosplenomegaly, and characteristic facial features. The syndrome affects multiple organ systems including the hepatobiliary system, gastrointestinal tract, cardiovascular system, genitourinary system, eyes, and craniofacial structures. The condition typically presents in the neonatal or early infantile period, often with jaundice related to biliary obstruction and associated congenital anomalies detected at birth or shortly thereafter. Liver disease can be progressive and may lead to significant hepatic complications. Cardiovascular defects vary in type and severity among affected individuals. There is no specific cure or targeted therapy for Hardikar syndrome. Management is supportive and symptom-directed, involving surgical correction of biliary atresia (such as the Kasai procedure), repair of cleft lip/palate, management of cardiac defects, and correction of intestinal malrotation when clinically indicated. Long-term follow-up by a multidisciplinary team including hepatologists, cardiologists, surgeons, and ophthalmologists is essential. Some patients may ultimately require liver transplantation if hepatic disease progresses to end-stage liver failure. Given the extreme rarity of the condition, with only a handful of cases reported in the medical literature, the natural history and long-term prognosis remain incompletely understood.
