A Rare Case with Systemic Lupus Erythematosus Manifested by two Different Neurologic Entities; Guillain Barre Syndrome and Posterior Reversible Encephalopathy Syndrome

Systemic lupus erythematosus (SLE) is an immune-mediated, lifelong disease characterized by quite heterogeneous neuropsychiatric manifestations. Herewith, we report the first rare co-incidental case with posterior reversible encephalopathy syndrome (PRES), Guillain Barre Syndrome (GBS), and (SLE). The coexistence of these neurological conditions in SLE patients could lead to delayed diagnosis and treatment due to this rare coalescence and clinical diversity. Currently, there are no specific, diagnostic radiological or laboratory biomarkers for neurological involvement in SLE. Awareness and, early recognition of neuropsychiatric involvements of the disease are important for timely appropriate treatment. Delayed treatment may cause permanent damage, poor prognosis, long term morbidity, and even death.

Evaluation of chromosomal DNA damage, cytotoxicity, cytostasis, oxidative DNA damage and their relationship with endocrine hormones in patients with acute organophosphate poisoning

Pesticides are commonly used compounds in agriculture. Especially, organophosphates (OPs) are among the extensively used pesticides. Therefore, OPs poisoning is common, especially in underdeveloped and developing countries. Primary aim of this study was to research the effects of acute OPs poisoning on genome instability in the individuals' lymphocytes with acute OPs poisoning both by using the cytokinesis-block micronucleus cytome (CBMN-cyt) assay to examine chromosome/genome damage, cell proliferation index and cell death rate and by using the plasma 8-hydroxy-2'-deoxyguanosine (8-OHdG) levels to determine oxidative DNA damage. Secondary aim of this study was also to assess whether a relation exists between endocrine hormones and the genome damage in acute OPs poisoning. In the study, blood samples were analysed of 13 patients before and after treatment admitted to the Department of Intensive Care Unit with acute OPs poisoning and of 13 healthy subjects of similar age and sex. The present study demonstrates that genome damage (micronucleus; MN and nucleoplasmic bridges; NPBs frequencies), apoptotic and necrotic cell frequencies increased in lymphocytes of patients with acute OPs poisoning before treatment and decreased after treatment. The present study also show that CBMN cyt assay parameters and 8-OHdG levels could be affected by some endocrine hormones such as E2, fT3, fT4, GH, IGF-1, FSH, LH, TSH, PRL, but not be related to ACTH and tT levels in acute OPs poisoning. In conclusion, it is believed that this is the first study to evaluate the chromosomal/oxidative DNA damage, cell proliferation, cell death and their associations with endocrine hormones in acute OPs poisoning. These preliminary findings need to be supported by further studies with larger sample sizes.
