A deficiência de ornitina transcarbamilase (DOTC) é um problema no ciclo da ureia, que é o processo do corpo para eliminar substâncias tóxicas como a amônia. A doença pode se apresentar de duas maneiras: uma forma grave, que surge logo após o nascimento e afeta quase exclusivamente meninos; ou formas que aparecem mais tarde na vida (parciais). Em ambos os casos, ocorrem episódios de acúmulo excessivo de amônia no sangue (hiperamonemia), que podem ser fatais e provocar problemas neurológicos.

Catalyzes the second step of the urea cycle, the condensation of carbamoyl phosphate with L-ornithine to form L-citrulline (PubMed:2556444, PubMed:6372096, PubMed:8112735). The urea cycle ensures the detoxification of ammonia by converting it to urea for excretion (PubMed:2556444)
Mitochondrion matrix
Ornithine carbamoyltransferase deficiency
An X-linked disorder of the urea cycle which causes a form of hyperammonemia. Mutations with no residual enzyme activity are always expressed in hemizygote males by a very severe neonatal hyperammonemic coma that generally proves to be fatal. Heterozygous females are either asymptomatic or express orotic aciduria spontaneously or after protein intake. The disorder is treatable with supplemental dietary arginine and low protein diet. The arbitrary classification of patients into the 'neonatal' group (clinical hyperammonemia in the first few days of life) and 'late' onset (clinical presentation after the neonatal period) has been used to differentiate severe from mild forms.

Emerging neurological and cognitive symptoms in patients with late-onset ornithine transcarbamylase deficiency: a narrative review.
Ornithine transcarbamylase deficiency (OTCD) is a rare X-linked urea cycle disorder associated with mild-to-severe neurological/cognitive symptoms that impact quality of life. Most patients are diagnosed with late-onset OTCD after 28 days of age. Emerging symptoms in adolescents and adults may not be recognized as effects of hyperammonemia, a common and potentially lethal complication of OTCD, and may contribute to substantial burden even when patients are diagnosed and treated. However, current reviews do not address this burden. Our aim is to raise awareness of neurological/cognitive manifestations of late-onset OTCD in adolescents and adults to reduce diagnostic delays and improve outcomes. Acutely, patients can present with signs of neurological impairment and psychiatric manifestations, which may be associated with a specific trigger or without known cause. Cognitive changes are more likely to be subacute or chronic, and onset may occur after hyperammonemia. As many late-onset OTCD cases are identified after presenting to emergency departments or primary care providers (often followed by hospital admission), education of frontline providers is needed to drive awareness, recognize symptoms, and improve patient care.

Pediatric liver transplantation for inherited metabolic disease-Current challenges.
Liver transplantation (LT) was first introduced in the early 1960s, with early paediatric experience marked by significant technical challenges and high risk. Advances in surgical techniques and immunosuppressive therapy in the late 1970s led to successful paediatric LT outcomes, while continued improvements throughout the 1980s and 1990s have enhanced survival and reduced complications. Current 10-year graft and patient survival rates for elective paediatric indications exceed 90%. Over the past two decades, LT has increasingly been used to treat inherited metabolic diseases (IMDs), which now account for 25-30% of paediatric LT. Initially recommended for tyrosinaemia type 1 in 1978 and later for urea cycle disorders such as ornithine transcarbamylase deficiency, LT can be curative when the metabolic defect is confined to the liver and partially corrective in conditions with extrahepatic involvement. As indications expand and earlier intervention is emphasized, this review examines the role of LT in IMDs, highlighting current concepts, challenges, and controversies.

Impact of long-term nitrogen scavenger therapy on clinical outcome in individuals with urea cycle disorders.
Principles of long-term medical management in individuals with urea cycle disorders (UCDs) encompass (1) a low protein diet, (2) supplementation of arginine and/or citrulline along with essential amino acids, nutrients, vitamins and trace elements, and (3) use of nitrogen scavenging agents to reduce recurrent hyperammonemic events (HAEs). These principles aim at providing metabolic stability, elimimation of chronic complications, and achievement of normal development as well as growth. A retrospective comparative analysis was performed by studying 138 individuals with male ornithine transcarbamylase deficiency (mOTC-D), citrullinemia type 1 (CTLN1) and argininosuccinic aciduria (ASA) based on in vitro residual enzymatic activity for severity-adjustment. Results show that individuals with mOTC-D, CTLN1 and ASA are at risk of progressive linear growth impairment, recurrent annual HAEs and an unfavorable neurocognitive outcome despite being under long-term nitrogen scavenging pharmacotherapy. No overall superiority among existing nitrogen scavenging agents with regard to the individual's metabolic stability, linear growth impairment and poor neurocognitive outcome was observed. Novel therapeutic strategies are urgently needed to ultimately improve health outcomes in individuals with UCDs in order to sufficiently meet guideline-specific goals.
Hyperammonemia-Associated Stroke-Like Episodes and Acute Liver Failure in an 11-Month-Old Infant With Probable Ornithine Transcarbamylase Deficiency: Diagnostic and Therapeutic Challenges in a Resource-Limited Setting.
Hyperammonemia outside the neonatal period is a time-critical emergency and may reveal a late-onset urea cycle disorder, including ornithine transcarbamylase deficiency (OTCD), which can be particularly challenging to recognize in females. We report the case of an 11-month-old female who presented with seizures and transient focal neurological deficits in the context of recurrent vomiting and acute hepatic dysfunction, with respiratory alkalosis and marked hyperammonemia accompanied by biochemical features compatible with a proximal urea cycle defect. Brain imaging showed stroke-like changes that were not consistent with a vascular territory, supporting a metabolic mechanism rather than primary ischemia. In a resource-limited setting where standard nitrogen-scavenging therapy and extracorporeal ammonia removal were not accessible, prompt catabolic control using strict protein restriction and high-calorie hydration was associated with biochemical recovery and clinical improvement, although mild residual weakness remained. This report highlights that early suspicion and immediate supportive management can be lifesaving when advanced diagnostics and targeted therapies are unavailable.
