Myasthenia gravis in pregnancy and birth: identifying risk factors, optimising care
ABSTRACT Women with myasthenia gravis (MG) have increased risk of pregnancy complications and an adverse pregnancy outcome. This study examined risk factors for such complications in order to improve the care for pregnant MG women. Through the Medical Birth Registry of Norway, 73 MG mothers with 135 births were identified. Their obstetrical and clinical records were examined. Data on pregnancy, delivery and the newborn were combined with information on mother's disease. The risk for neonatal MG was halved if the mother was thymectomized (P = 0.03). Children with neonatal MG were more likely to display signs of foetal distress during delivery (P = 0.05). Only in one-third of the pregnancies did the patient see a neurologist during pregnancy. These patients used MG medication more often during pregnancy (P = 0.001), and were more likely to be thymectomized (P = 0.007). They also had a higher rate of elective sections (P = 0.009). Thymectomy may have a protective effect against neonatal MG. Neonatal MG can cause foetal distress during delivery. Most MG women benefit from being examined by a neurologist during pregnancy, to minimize risks and select the best delivery mode in collaboration with obstetricians.

ABSTRACT: Neurological conditions during pregnancy can be pregnancy related or can be caused by exacerbation of pre-existing neurological disorders. Knowledge of pre-existing epilepsy or myasthenia gravis in women of childbearing age requires preconception counselling by neurologist and planned pregnancy. Possible adverse effects of medication on the foetus should be balanced with the risk of uncontrolled symptoms. Interdisciplinary management before, during and after pregnancy is recommended. New acute neurological symptoms in pregnant or postpartum women should lead to an urgent neurological review. Patients need a thorough diagnostic evaluation that targets a range of serious pathological conditions that are either unique to (e.g. eclampsia) or arise more frequently (e.g. cerebral venous thrombosis) in this population. Most of these conditions are infrequent and require a specialized and multidisciplinary management. Treatment is challenging due to risks to the unborn child.Best practice & research.

ABSTRACT: Patients with autoimmune myasthenia gravis (MG) should be further classified before initiating therapy, as treatment response varies for ocular versus generalised, early onset versus late onset, and acetylcholine receptor antibody positive versus MuSK antibody positive disease. Most patients need immunosuppression in addition to symptomatic therapy. Prednisolone and azathioprine represent first choice drugs, whereas several second choice options are recommended and should be considered. Thymectomy should be undertaken in MG with thymoma and in generalised, early-onset MG. For MG crises and other acute exacerbations, intravenous immunoglobulin (IvIg) and plasma exchange are equally effective and safe treatments. Children and females in child bearing age need special attention regarding potential side effects of immunosuppressive therapy. MG pathogenesis is known in detail, but the immune therapy is still surprisingly unspecific, without a pin-pointed attack on the defined disease-inducing antigen-antibody reaction being available.10/2011; 2011:847393.
