Associations between phenotypes of preeclampsia and thrombophilia.

OBJECTIVES: Preeclampsia complicates 2-8% of all pregnancies. Studies on the association of preeclampsia with thrombophilia are conflicting. Clinical heterogeneity of the disease may be one of the explanations. The present study addresses the question whether different phenotypes of preeclampsia are associated with thrombophilia factors. Study design We planned a retrospective cohort study. From 1985 until 2010 women with preeclampsia were offered postpartum screening for the following thrombophilia factors: anti-phospholipid antibodies, APC-resistance, protein C deficiency and protein S deficiency, hyperhomocysteineamia, factor V Leiden and Prothrombin gene mutation. Hospital records were used to obtain information on phenotypes of the preeclampsia and placental histology. RESULTS: We identified 844 women with singleton pregnancies who were screened for thrombophilia factors. HELLP complicated 49% of pregnancies; Fetal growth restriction complicated 61% of pregnancies. Early delivery (<34th week) occurred in 71% of pregnancies. Any thrombophilia factor was present in 29% of the women. Severe preeclampsia was associated with protein S deficiency (p=0.01). Fetal growth restriction was associated with anti-phospholipid antibodies (p<0.01). Early onset preeclampsia was associated with anti-phospholipid antibodies (p=0.01). Extensive placental infarction (>10%) was associated with anti-phospholipid antibodies (p<0.01). Low placental weight (<5th percentile) was associated with hyperhomocysteineamia (p=0.03). No other associations were observed. CONCLUSIONS: Early onset preeclampsia, especially if complicated by fetal growth restriction, are associated with anti-phospholipid antibodies. Other phenotypes of preeclampsia, especially HELLP syndrome, were not associated with thrombophilia. We advise only to test for anti-phospholipid antibodies after early onset preeclampsia, especially if complicated by fetal growth restriction. We suggest enough evidence is presented to justify no further studies are needed.

PP045. Different associations between phenotypes of preeclampsia and thrombophilias.

INTRODUCTION: Studies on the association of preeclampsia (PE) with thrombophilias (TRPH) are conflicting. Clinical heterogeneity of PE may be one of the explanations. OBJECTIVES: The present study addresses the question whether different phenotypes of PE are associated with subtypes of TRPH. METHODS: In this retrospective cohort study between 1985 until 2010 women with PE were offered postpartum screening for the following TRPH: anti-phospholipid antibodies (APA), APC-resistance, protein C deficiency and protein S deficiency (PSD), hyperhomocysteinemia (HCY), factor V Leiden and Prothrombin gene mutation. RESULTS: 890 Women with PE were screened for TRPH. 49% Also had HELLP, 60% had IUGR, 71% delivered before the 34th week. One or more TRPH factors were present in 31% of the women. Severe PE was associated with PSD (p=0.01). IUGR (p<0.01) was associated with APA (p<0.01) and PSD (P=0.03). Early onset PE was associated with APA (P, 0.01). More than 10% of placental infarction was associated with APA (p<0.01). Placental weight below the 5th percentile was associated with HCY (p=0.03). Other phenotypes of PE and TRPH were not associated. CONCLUSION: Severe and early onset PE, especially if complicated by IUGR, are associated with APA and PSD. Other phenotypes of PE, especially HELLP syndrome, were not associated with TRPH. We advise to screen for APA and PSD after severe and early onset PE, especially if complicated by IUGR. We do not recommend screening for TRPH in other phenotypes of PE.

[Hallucinations attributed to djinns]. / Hallucinaties toegedicht aan djinns.

Individuals with an Islamic background who suffer from hallucinations often attribute these to djinns, invisible beings. The treatment of these hallucinations is complicated by the patients' reluctance to discuss them, and by their doubts concerning the usefulness of a biomedical treatment for a problem which they experience as metaphysical in nature. In this clinical lesson, we present case studies of three Moroccan patients who attributed their hallucinations to djinns. The first was a 30-year-old factory worker whose compulsive complaints had started when he saw a white figure in the basement who asked him 'What are you doing here?' The psychiatric diagnosis was obsessive-compulsive disorder. The patient was prescribed cognitive behavioural therapy, an SSRI and a consultation by the imam, but he refused. The second patient was a 25-year-old unemployed man, who had auditory hallucinations, delusions, behavioural problems, and alcohol and cannabis abuse. He heard voices which he attributed to maleficent djinns. He was diagnosed with schizophrenia, but his compliance with antipsychotics was insufficient. The imam who was consulted reassured him that his complaints were not caused by djinns. After prolonged treatment with clozapine and cutting down on cannabis use the patient recovered sufficiently to be discharged. The third patient was a 26-year-old unemployed woman who was hearing voices that her imam thought were caused by a djinn. She was examined because of serious self-mutilation and was diagnosed with a schizoaffective disorder. Treatment with an antipsychotic, lithium and valproic acid and a consultation by a second imam, who found no signs of evidence of djinns, was successful. We recommend to ask individuals with an Islamic background specifically whether djinns might be involved, especially in cases of mental problems and unexplained symptoms, and to seek the cooperation of a qualified imam or traditional healer for treatment purposes.
