The diagnosis of acute intermittent porphyria combined with seizures: Case report.

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.

Lovastatin induces neuroprotection by inhibiting inflammatory cytokines in 6-hydroxydopamine treated microglia cells.

PURPOSE/AIM: This study aims to investigate the impact of lovastatin on neuroinflammation in 6-OHDA-treated microglia cells. MATERIALS AND METHODS: 6-Hydroxydopamine (6-OHDA)-treated microglia cells were used to investigate the neuroprotective nature of lovastatin. After incubation with 6-OHDA and/or lovastatin for 24 h, test kits were used to detect the levels of LDH and glutamate, which were released from PC12 cells exposed to different culture media. The mRNA levels of TNF-α, IL-6 and IL-1ß were determined by RT-PCR and the protein levels were analyzed by Western blot. RESULTS: LDH and glutamate levels in 6-OHDA-incubated PC12 cells increased, when compared with those in the controls, while incubation with lovastatin inhibited this elevation. The expression levels of TNF-α IL-6 and IL-1ß were significantly upregulated after treatment with 6-OHDA. The 6-OHDA-stimulated mRNA and protein levels of TNF-α IL-6 and IL-1ß were reduced by lovastatin. CONCLUSIONS: Our results suggest that Lovastatin is able to induce neuroprotection by inhibiting inflammatory cytokines. The data provide direct evidence of the potential application of lovastatin for the treatment of neuroinflammatory diseases.

Inflammatory response in Parkinson's disease (Review).

Parkinson's disease (PD) is one of the most common age­related neurodegenerative diseases, which results from a number of environmental and inherited factors. PD is characterized by the slow progressive degeneration of dopaminergic (DA) neurons in the substantia nigra. The nigrostriatal DA neurons are particularly vulnerable to inflammatory attack. Neuroinflammation is an important contributor to the pathogenesis of age­related neurodegenerative disorders, such as PD, and as such anti­inflammatory agents are becoming a novel therapeutic focus. This review will discuss the current knowledge regarding inflammation and review the roles of intracellular inflammatory signaling pathways, which are specific inflammatory mediators in PD. Finally, possible therapeutic strategies are proposed, which may downregulate inflammatory processes and inhibit the progression of PD.
