Abstract
RATIONALE: Acute intermittent porphyria (AIP) is a rare metabolic disorder affecting heme production due to enzyme porphobilinogen deaminase deficiency. Diagnosing acute intermittent porphyria is difficult because its symptoms interrelate with those of other common diseases. When AIP is combined with seizures, the diagnosis process is more complicated. This case report shows all tests and criteria used to arrive at the final stage of diagnosis. PATIENT CONCERNS: The patient complained of severe abdominal pain, nausea, vomiting, and intermittent convulsions. Her medical history shows she had abdominal pain, mainly dull pain in the left upper abdomen. DIAGNOSES: Different symptomatic tests were done, and the cause of her symptoms was uncertain. A urine sun drying test was then done and confirmed the presence of porphyrin used to diagnose AIP. A genetic test was done after the patient was discharged, and AIP diagnosis was confirmed. INTERVENTIONS: Acute intermittent porphyria treatment was administered. OUTCOMES: The patent recovered fully. LESSONS: It is essential to consider acute intermittent porphyria diagnosis in patients having unexplained severe abdominal pain associated with neurological and psychiatric symptoms. Since AIP is a rare disease with a high mortality rate when not treated early, Clinical practices should include AIP as one of the tests done on patients showing these symptoms at an early stage. The fastest way to identify this is to conduct a urine test. The change of color from brown to reddish color is a diagnostic indicator of AIP. This strategy helps reduce misdiagnoses and delayed treatment of the right disease.
