Chronic renal failure; an important feature of the Laurence-Moon-Biedl syndrome

Bardet-Biedl syndrome: Delayed diagnosis in a 14-year-old child with end-stage renal disease

Bardet-Biedl syndrome (BBS) is a rare autosomal recessive ciliopathic disorder. Because of its low prevalence and wide spectrum of clinical features, many patients remain undiagnosed. We report a case of a 14-year-old boy with a typical phenotype of BBS who remains undiagnosed until the development of end-stage renal disease.

Bangladeshi Case Series of Bardet-Biedl Syndrome

A rare multisystemic, ciliopathic autosomal recessive disorder called Bardet-Biedl syndrome (BBS) primarily affects children of consanguineous marriages. Both men and women are affected by it. It is characterized by some major and many minor features to aid in the clinical diagnosis and management. Here, we reported two Bangladeshi patients (a 9-year-old girl and 24-year-old male) who were presented with various major and minor features of BBS. Both patients came to us with the symptoms including excessive weight gain, poor vision, and learning disabilities with polydactyly. Our case 1 presented four primary features (retinal degenerations, polydactyly, obesity, and learning deficits) and six secondary features (behavioral abnormality, delayed development, diabetes mellitus, diabetes insipidus, brachydactyly, and LVH), whereas case 2 presented five major criteria (truncal obesity, polydactyly, retinal dystrophy, learning disabilities, and hypogonadism) and six minor criteria (strabismus and cataract, delay in speech, behavioral disorder, developmental delay, brachydactyly and syndactyly, and impaired glucose tolerance test). We diagnosed the cases as BBS. Because there is no specific treatment for BBS, we highlighted the importance of diagnosing it as early as possible so that comprehensive and multidisciplinary care can be offered to prevent avoidable morbidity and mortality.

Laurence-Moon-Bardet-Biedl Syndrome: A Case Report

Laurence-Moon-Bardet-Biedl syndrome (LMBBS), a rare autosomal recessive defect, mostly occurs in children born from consanguineous marriages. The major features of this syndrome are cone-rod dystrophy, polydactyly, obesity, learning disabilities, hypogonadism in males, renal anomalies, nystagmus, speech disorders, developmental delay, polyuria/polydipsia, ataxia, and poor coordination/clumsiness. In this report, we present a case of a 19-year-old man with pain and swelling of the left ankle and knee joints because of which he could not walk, with an onset of loose stools since a week. He presented with multiple non-itchy hyperpigmented macules on his face and back, polydactyly in his left foot, central obesity, proteinuria, macrocytic anemia, low intelligence quotient, reduced power in the left lower limb, reduced plantar reflexes, nystagmus, pigmented black lesions in the temporal retina on fundoscopy, a micropenis, absent pubic and axillary hair, and a small scrotum containing testes. The patient was diagnosed with LMBBS.

Laurence-Moon-Bardet-Biedl Syndrome with Coexisting Abdominal Distension and Positive Fluid Thrill: A Rare Manifestation Reported in Karachi, Pakistan

Laurence-Moon-Bardet-Biedl syndrome (LMBBS) is a rare autosomal recessive (AR) disorder. It is characterized predominantly by hypogonadism, polydactyly, retinitis pigmentosa, obesity, and mental retardation. Herein, we present a classic case of LMBBS with generalized body edema, abdominal distension, and positive fluid thrill in a 32-year-old male. LMBBS patients are friendly with a happy predisposition, proper management, and regular examinations should be done in order to maintain healthy organ function and to avoid an early death. Renal failure is the most common cause of mortality in LMBBS patients.

Bardet-Biedl syndrome

This case report describes the presentation of a patient with Bardet-Biedl syndrome. Bardet-Biedl Syndrome is an autosomal recessive condition that includes retinal dystrophy, dystrophic extremities (commonly polydactyly), obesity, hypogenitalism, and renal disease. Cognitive deficit has also been considered part of the syndrome. The historically associated Laurence-Moon syndrome includes spastic paraparesis but not the obesity and polydactyly. They are now considered separate conditions. The most common feature of Bardet-Biedl syndrome is retinal dystrophy. The appearance of the retina in the condition is quite variable with typical retinitis pigmentosa being present in only a minority of cases. The associated optic atrophy can be primary in nature and might play a role in the decreased central vision. Diagnosis of the condition is important for visual prognosis and low vision management. The renal disease often goes undetected until specific radiological testing is done after diagnosis of Bardet-Biedl syndrome. This is significant in that early death often occurs in this condition because of the renal disease.

Pediatric renal transplantation in Laurence-Moon-Biedl syndrome

Two cases of renal transplantation in pediatric patients with Laurence-Moon-Biedl syndrome are reported. Immunosuppressive therapy consisted of cyclosporine, prednisone and azathioprine. Renal function has been good but both patients developed morbid obesity.
