Abstract

De Barsy syndrome (DBS), synonymously known as autosomal recessive cutis laxa type III, is an extremely rare condition clinically characterized by cutis laxa, a progeroid appearance, and ophthalmologic abnormalities. We present here an account of 5-year follow-up since the birth of an Indian boy with DBS, who had a few rare and unusual manifestations. In addition, our case probably represents the first reported case of DBS from India.

 Introduction



The De Barsy syndrome (DBS) is an extremely rare autosomal recessive disorder characterized by cutis laxa, progeroid look, and corneal clouding. [1] After the initial description by De Barsy et al. in 1968, only a few cases have been reported in the English-language literature till date. [1],[2],[3] The disorder was recognized as a subgroup of the cutis laxa syndrome (cutis laxa type III) and expressed in variable presentations involving ocular, skeletal, dermatologic, and neurologic abnormalities. [1] We describe here, the evolution of a child with DBS with a few rare and unusual manifestations. We present here an account of a 5-year follow-up of this boy since birth. Furthermore, our case probably represents the first reported case of DBS from India.

 Case Report



A newborn Muslim boy from Eastern India, born out of consanguineous parentage, was admitted to the neonatal care unit of our hospital. His mother had a normal pregnancy. However, her late antenatal ultrasonography (USG) showed features of marked intrauterine growth retardation (IUGR). Following normal delivery, the baby needed no active resuscitation and the immediate postnatal period was uneventful. His other three siblings and first-degree relatives were normal. On examination, the boy showed asymmetrical IUGR. His weight, length, and head circumference were 1.85 kg (0.65 kg below the 3 rd percentile), 43.2 cm (3.1 cm below the 3 rd percentile) and 32.8 cm (0.7 cm above 3 rd percentile), respectively.

We noted that he had distinctive dysmorphic features [Figure 1] including small face with progeroid look, asymmetrical head with widely open fontanelles, thin sparse scalp hair, small nose with long philtrum, large and low set ear, and small mouth. Hypertrichosis was evident over the forehead. He had thin translucent lax skin with prominent superficial blood vessels. The nails were normal. Examination of the musculoskeletal system showed flexion deformity of both wrist joints with claw-like fingers and subluxation of multiple small joints. In the lower limbs talipes with equinus deformity was present. The baby was hypotonic. He also had large bilateral inguinal hernia [Figure 2]. Other systemic examinations did not reveal any abnormality. Complete hemogram and biochemical panels including thyroid, hepatic, and renal functions were normal. USG of the abdomen, echocardiography, and skeletal X-ray did not reveal any abnormality. His karyotype was normal.{Figure 1}{Figure 2}

At the age of 2 months, the progeroid look and corneal opacity became more apparent, and strabismus was evident. The inguinal hernia also became more prominent, and he developed torticolis.

During follow-up, delayed developmental milestones were noted. Social smile developed at 4 months of age, neck holding at 6 months, sitting without support at 18 months, and walking at 2.5 years. He developed generalized tonic-clonic convulsion at the age of 3.5 years. Electroencephalography (EEG) at that time showed features of generalized seizure disorder and he was put on the antiepileptic drug. Computerized tomography scan of the brain (done twice) showed normal brain parenchyma, except features of dysraphism of the splenium of the corpus callosum and a mild degree of colpocephaly [Figure 3]. Magnetic Resonance Imaging of the brain was attempted, but could not be done due to repeated failure to sedate the child. At the time of last follow-up, he was 5-year-old. He could walk with an unsteady gait.{Figure 3}

His weight was10 kg (4.3 kg below the 3 rd percentile), height was 93 cm (8.2 cm below the 3 rd percentile). He had a progeroid and grimacing face, convergent squint, asymmetrical head with frontal bossing, and torticolis. His head circumference is 46.5 cm (1.4 cm below the 3 rd percentile). Neurologically, he had generalized hypotonia, athetoid movements of limbs, and brisk tendon jerks. He has moderate mental retardation. He is socially adjusted, plays with friends, and can utter a few meaningful words. We needed to accelerate the dose of the antiepileptic drug for his recurrence of convulsion.

Dermatological evaluation at that time revealed thin, atrophic, wrinkled skin especially over his dorsum of the hands and feet with reduced subcutaneous fat. Teeth and nails were well-developed. Small joints were hyperextensible. Movements of the large joints were normal. Inguinal hernia had been successfully operated and torticolis was partially corrected [Figure 4]. Skin biopsy, done twice on the 3 rd day after birth and at the age of 4.5 years, showed hyperkeratosis, but an otherwise normal epidermis, fragmented collagen in the dermis with preservation of adnexae. Verhoeff van Gieson stain showed markedly reduced elastic tissue fibers in the mid and lower dermis and presence of small fragmented elastic fibers [Figure 5]. Based on the clinical features and histological findings, a diagnosis of DBS was made.{Figure 4}{Figure 5}

 Discussion



Since the initial description of DBS, only a few cases have been described in the literature with diverse phenotypic features. The exact pathogenesis of DBS remains elusive.

Elastic fiber abnormality in the form of sparse, small, fragmented fibers in the dermis with small fibers per unit area is probably the main underlying cause of this disorder. Molecular hybridization studies demonstrated reduced elastin mRNA steady-state levels as compared with age-matched control individuals. The progeroid appearance originates due to hypoplasia of the dermis. [3],[4],[5]

There is no racial variation, but male predominance has been noted. [2] History of the reported cases may suggest an autosomal recessive mode of inheritance and affection of other siblings in the same family has been noted. [4],[6] They have dysmorphic features such as the progeroid look, prominent forehead; large low set dysplastic ears, sparse hair, small mouth with thin lips, and small upturned nose. The majority (96%) of the affected children have IUGR and show postnatal growth retardation. [2]

Besides cutis laxa, thin translucent skin with reduced subcutaneous fat has been described, and inguinal and umbilical hernia has been noted in 34% cases. [2],[7]

Congenital corneal opacity due to degeneration of Bowman's membrane was seen in 48% of cases and cataract, myopia, strabismus, and blue sclera has been seen in varying proportion. [8]

Developmental delay since birth has been seen in 76% of cases while 48% showed severe delay. Hypotonia, athetoid movement, grimacing, and seizures have also been reported. [2],[6],[7] Hyper extensible joints with subluxation or dislocation of small joints, sclerosis, pectus excavatum, congenital vertical talus and hip dysplasia or dislocation have all been described. [9],[10]

Although nonspecific EEG changes and ventricular dilatation have been described in the literature, dysraphism of the splenium of corpus callosum with a mild degree of colpocephaly was a unique feature in our patient. The lifespan of the patients with this syndrome is unknown. To the best of our knowledge, the oldest reported case was of a 24-year-old at the time of reporting. [6]

Other progeroid conditions are the close differential diagnoses of DBS. However, distinctive morphological features along with skin biopsy will help distinguishing others. Mutation in PYCR1, coding for a mitochondrial enzyme involved in proline metabolism may have a causative role in DBS. [11] However, the genetic study could not be performed in the present case because of local unavailability and financial constraints. Based on the specific mutation patterns, DBS may also be divided into an autosomal recessive cutis laxa type IIIA (due to mutations in ALDH18A1) and autosomal recessive cutis laxa type IIIB (due to mutations in PYCR1). [12],[13] Till date, less than 30 cases of DBS have been reported in the PubMed, Medline, and PubMed Central databases. We have searched these databases, Google Scholar, and standard textbooks with the terms such as, "De Barsy," India, and "Indian." However, in spite of our best effort, we could not find any report in Indian population. As there is no specific therapy for this condition, we seek to emphasize the importance of regular follow-up in order to address the different evolving problems in these patients.
