Allgrove syndrome

Allgrove syndrome or triple A (3A) syndrome is a multisystem disorder which classically involves the triad of esophageal achalasia, alacrima, and adrenal insufficiency due to adrenocorticotropin hormone insensitivity. It follows an autosomal recessive pattern of inheritance and is associated with mutations in the AAAS (achalasia-addisonianism-alacrima syndrome) gene. Since its first description in 1978, the knowledge on clinical and genetic characteristics has been expanding; however, the current literature is limited to case reports and case reviews...

Allgrove syndrome (AS) is a rare disease with broad neurological involvement. Neurodegeneration can affect spinal motor neurons, Purkinje cells, striatal neurons, and the autonomic system. The mechanisms that lead to neuronal loss are still unclear. Recessive mutations in the AAAS gene affect the encoded protein Aladin, which would normally localize to the cytoplasmic face of the nuclear membrane as part of the nuclear pore complex (NPC). While the NPC is known to be a key factor for nucleo-cytoplasmic transport, the precise role of Aladin has not been elucidated yet...

Triple A syndrome or Allgrove's syndrome is a rare autosomal recessive disorder usually manifested with three main clinical features, i.e. achalasia, alacrimation and adrenal inadequacy. Sometimes, it presents with polyneuropathy and neurological complications. Here, we report a case of a 7-year girl presenting with features of weight loss who was diagnosed with adrenal insufficiency at the age of 7 years while achalasia was diagnosed at the age of 3 years. First manifestation was achalasia and at that time, alacrimation was also defected...

BACKGROUND: Allgrove syndrome is a multisystem disorder first described in 1978 and is classically associated with esophageal achalasia, alacrima, and adrenal insufficiency. Allgrove syndrome is caused by homozygous and/or compound heterozygous mutations on Chromosome 12q13, designated as "AAA" (Achalasia, Addisonianism Alacrima). AAA encodes the protein ALADIN (Alacrima, Achalasia, aDrenal Insufficiency Neurologic disorder), a member of the nuclear porin family forming the nuclear pore complex...

The association achalasia and non tuberculous Mycobacteria lung infection is described in the literature. Most of the time Mycobacterium Fortuitum is responsible of aspiration pneumonia that didn't respond to usual antibiotic therapy. We report a new case about a 15 year-old woman with Allgrove's syndrome history. The chest imaging showed a right pulmonary condensation and the diagnosis was bacteriological. Mycobacterium Fortuitum resistant to Rifampicin, isoniazid, Pyrazinamide and ethamabutol was isolated...

The association between achalasia and no tuberculosis mycobacterial   lung infection is well described in the literature. MycobactériumFortuitum is often responsible, and the clinical's presentation   is an aspiration pneumonia resistant to usual antibiotic therapy. We report the case of a 15 year-old patient with the history of Allgrove syndrome. The chest imaging showed right lung congestion; the diagnosis was bacteriological and MycobactériumFortuitum resistant to rifampicin, isoniazid, pyrazinamide and ethambutol was isolated...

CONTEXT: The α subunit of the stimulatory G protein (Gαs) links numerous receptors to adenylyl cyclase. Gαs, encoded by GNAS, is expressed predominantly from the maternal allele in certain tissues. Thus, maternal heterozygous loss-of-function mutations cause hormonal resistance, as in pseudohypoparathyroidism type Ia, whereas somatic gain-of-function mutations cause hormone-independent endocrine stimulation, as in McCune-Albright syndrome. OBJECTIVE: We report two unrelated boys presenting with a new combination of clinical findings that suggest both gain and loss of Gαs function...

Allgrove syndrome is a rare autosomal recessive syndrome of unknown prevalence. The first case of Allgrove syndrome was reported in 1978 by Allgrove. It is characterized by triad of achalasia, alacrima and adrenal hypoplasia. There are also associated autonomic and neurological manifestations. We report the case of a 7 years old boy being treated for achalasia cardia, presented with fits and altered sensorium which on further investigations was found to be due to adrenal insensitivity (Raised ACTH level, low Cortisol level, and normal Aldosterone and Renin ratio)...

BACKGROUND: Allgrove syndrome is a rare autosomal recessive disorder characterized by the triad of achalasia, alacrimia and adrenal insufficiency. It is caused by the mutations of the AAAS gene located on chromosome 12q13. The c.1331 + 1G > A mutation is one of the most common described in North Africa including Tunisia, Algeria and Libya. We report here the clinical and genetic profile of a Moroccan family with Allgrove syndrome. CASE PRESENTATION: A Moroccan sister and brother born to consanguineous parents were found, at the ages of twelve and fifteen months old respectively, to have alacrimia and isolated glucocorticoid deficiency...

Triple A (Allgrove) syndrome, an autosomal recessive disease is characterized by achalasia, alacrimia and ACTH-resistant adrenal failure with progressive neurological syndrome including central, peripheral and autonomic nervous system impairment, and mild mental retardation. The triple A syndrome gene, designated AAAS, localized on chromosome 12q 13 encodes for a 546 amino acid protein called ALADIN (Alacrimia-Achlasia-Adrenal Insufficiency and Neurologic disorder). This report relates to two sisters, aged 8 and 12 years, who had vomiting, muscle weakness, alacrimia, excessive fatigue and dysphagia...

Allgrove syndrome, also known as Triple A syndrome, is a rare autosomal recessive genetic disease characterized by three signs: esophageal achalasia, adrenocorticotropic hormone refractoriness, and alacrima. A 31-year-old male presented to our hospital for treatment of difficulty swallowing caused by esophageal achalasia. Because he had complicating alacrima, a neurologic disease, and a family history of consanguineous marriage, a genetic neurologic disease was suspected. Then, a mutation in the achalasia-addisonianism-alacrima syndrome gene was identified...

BACKGROUND: Triple A syndrome (or Allgrove syndrome) is a rare autosomal recessive disorder characterized by alacrima, achalasia, adrenal insufficiency and autonomic/neurological abnormalities. The majority of cases are caused by mutations in the AAAS gene located on chromosome 12q13. However, the clinical picture as well as genetic testing may be complex since symptomatology is variable and mutations cannot be identified in all clinically diagnosed patients. We present two unrelated patients with triple-A syndrome illustrating the importance of alacrima as an early clinical sign...

OBJECTIVE: Triple-A or Allgrove syndrome is an autosomal recessive disorder due to mutations in the AAAS gene, which encodes a nucleoporin named ALADIN. It is characterized by a classical clinical triad: alacrima, achalasia and adrenal insufficiency, the canonic symptoms that are associated with progressive peripheral neuropathy. Only a few cohorts have been reported. The objective of the present study was to characterize the various spectra of adrenal function in Triple-A patients. METHODS: A retrospective clinical and biological monitoring of 14 patients (10 families) was done in a single multidisciplinary French center...

Allgrove or triple A syndrome is a rare autosomal recessive disorder that can present with a variable range of multi-system manifestations, including optic atrophy, cerebellar ataxia, upper and lower motoneuron signs and various neuropathic abnormalities. These cases are a diagnostic challenge, particularly when the eponymous combination of achalasia, Addisonianism and alacrima is incomplete. Therefore, it is in the differential diagnosis for multisystem conditions and should be known to pathologists who diagnose disorders of skeletal muscle...

Triple-A syndrome, also known as Allgrove syndrome, is a rare autosomal recessive disorder. The 3 features of this syndrome are achalasia, adrenal insufficiency, and alacrima. Achalasia could be the first manifestation of the triple-A syndrome; however, its etiology is unclear. Alacrima is generally asymptomatic but can be detected by obtaining patient history. Although adrenal insufficiency could have manifestations such as asthenia, it might be wrongly diagnosed as muscle fatigue. Vitamin D and calcium supplements are usually prescribed for the prevention of osteoporosis...

AIM: To investigate the incidence of achalasia in Algeria and to determine its clinical and para-clinical profile. To evaluate the impact of continuing medical education (CME) on the incidence of this disease. METHODS: From 1990 to 2014, 1256 patients with achalasia were enrolled in this prospective study. A campaign of CME on diagnosis involving different regions of the country was conducted between 1999 and 2003. Annual incidence and prevalence were calculated by relating the number of diagnosed cases to 10(5) inhabitants...

BACKGROUND Allgrove syndrome, or triple "A" syndrome (3A syndrome), is a rare autosomal recessive syndrome with variable phenotype, and an estimated prevalence of 1 per 1,000,000 individuals. Patients usually display the triad of achalasia, alacrima, and adrenocorticotropin (ACTH) insensitive adrenal insufficiency, though the presentation is inconsistent. CASE REPORT Here, the authors report a case of Allgrove syndrome in a pediatric patient with delayed diagnosis in order to raise awareness of this potentially fatal disease as a differential diagnosis of alacrima...

Triple A syndrome, formerly known as Allgrove syndrome (AS), is characterized by achalasia, alacrima and adrenal insufficiency. Here we report an adolescent male with adrenal insufficiency who developed severe malnutrition secondary to a delayed diagnosis of achalasia. The severe malnutrition in our patient led to superior mesenteric artery (SMA) obstruction syndrome. Severe malnutrition to the point of SMA syndrome has not been previously described in the literature in Triple A syndrome.

Idiopathic achalasia is an archetype esophageal motor disorder, causing significant impairment of eating ability and reducing quality of life. The pathophysiological underpinnings of this condition are loss of esophageal peristalsis and insufficient relaxation of the lower esophageal sphincter (LES). The clinical manifestations include dysphagia for both solids and liquids, regurgitation of esophageal contents, retrosternal chest pain, cough, aspiration, weight loss and heartburn. Even though idiopathic achalasia was first described more than 300 years ago, researchers are only now beginning to unravel its complex etiology and molecular pathology...
