A CLINICAL STUDY OF NEUROLOGICAL COMPLICATIONS IN PREGNANCY AND UPTO 6 WEEKS POSTPARTUM.

BACKGROUND

Several neurological conditions may appear during pregnancy, that are either unique to or occur with increased frequency during pregnancy and puerperium. Pre-existing disorders such as epilepsy may worsen in one-third of pregnant patients and seizures are common during peripartum period. Changes in haemodynamics, blood volume and hormonal effects on the vessel wall increase the risk of cerebrovascular disorders during pregnancy and the postpartum period. Cerebral venous sinus thrombosis is common in the postpartum period. Brain tumours may enlarge during pregnancy because of fluid retention and the presence of oestrogen and progesterone receptors on the tumour cells. Neurological disorders may influence the management of obstetric outcomes. In this study, the common neurological problems during pregnancy and six weeks of postpartum period are discussed.

Aims and Objectives of the Study

To study the neurological disorders and clinical features occurring during pregnancy and 6 weeks of postpartum.

MATERIALS AND METHODS

This was a descriptive study carried out in Osmania General Hospital OPD/IPD with neurological symptoms, Hyderabad (December 2015-January 2018). 67 patients were included in the study and consent was taken from them. All the pregnant women attending OP and admitted as inpatients in Osmania General Hospital were included in this study. Neurological disorders due to trauma, infections and obstetrical procedure were excluded from this study. Age, duration of pregnancy and history were noted. Detailed neurological examination was done. Basic and relevant investigations were done including brain and spine imaging, CSF analysis, EEG, NCS, 2D echo and ANA profile whenever necessary. MS Excel 2010 was used for descriptive statistics.

Inclusion Criteria

Sixty seven pregnancy patients and postpartum 6 weeks of post-delivery with neurological symptom patients who met with inclusion criteria and were included in the study.

RESULTS

Most patients belonged to age between 21-25 years (62%) as shown in Figure 1.

Most of the patients were in postpartum period (41%) followed by second trimester (32%) as shown in Figure 2.

Out of total sixty seven cases, seizures were found to be the most common presentation followed by cerebrovascular disorders. Other patients presented with facial nerve palsy, chorea and GBS as shown in Table 1.

Most patients with seizures were in second (45%) and third trimesters (35%) as shown in Table 2.

24 patients presented with cerebrovascular disorders, out of which PRES was the most common as shown in Figure 3.

Most of the cerebrovascular disorder events occurred during the postpartum period as shown in Table 3.

Three patients presented with chorea. No aetiology was found in two cases. One had Wilson's disease. Two had presented during the first trimester and the other in the second trimester. Three patients had presented with facial nerve palsy. One patient had bilateral facial nerve palsy during postpartum period. Other two patients had presented during 2nd trimester with unilateral facial nerve palsy. Three patients had presented with GBS. One patient had presented during second trimester. Other two patients had presented during postpartum period. One case who presented with raised intracranial pressure symptoms during 2nd trimester was found to have Glioblastoma. Another case of primi presenting during postpartum period with facial nerve palsy was found to have glioma. One patient had Neurofibroma.

DISCUSSION

A wide range of neurologic conditions can affect women during pregnancy and puerperium. The primary neurological disorders studied in relation to pregnancy include eclampsia, strokes, epilepsy, benign intracranial hypertension, CNS tumours, Bell's palsy, obstetric pressure palsies, demyelinating diseases of the central/ peripheral nervous system and neuromuscular junction disorders (Myasthenia gravis). Neurological diseases may be incidental to pregnancy (e.g. meningitis). Patients may also present with secondary neurological disorders such as metabolic encephalopathies secondary to hypoxia-ischaemia, hypoglycaemia, hepatic failure, azotaemia, hypercalcaemia and nervous system disorders secondary to nutritional deficiencies and endocrine dysfunction.

Sixty seven cases presented to our hospital with various neurological disorders. Out of 67 thirty one cases of generalised seizures, eleven cases of cerebrovascular disorders, in that three ischaemic, two haemorrhagic and six cases of CSVT, three cases each of neoplasms, peripheral neuropathy and movement disorders were reported. Among three cases of neoplasm one was glioma, one was glioblastoma and the other presented with neurofibromatosis. All cases of peripheral neuropathy were GBS. Among three cases of movement disorders, all presented with chorea. Two were diagnosed as chorea gravidarum and one was diagnosed to be Wilson's disease.

This Table 4 shows comparative analysis of different neurological illnesses in pregnancy and puerperium across various studies. Epilepsy was found to be major neurological ailment varying between 23-63%, except one study conducted by Agarwal et al [5] which showed higher incidence of cerebrovascular disease. The other disorders like CNS tumours, cranial nerve palsies, neuropathies and movement disorders constitute lesser proportion of cases and distribution is also variable.

There are a number of factors that can affect seizure frequency in women with epilepsy who are pregnant. The major factors are hormonal changes that accompany the pregnant state, changes in behaviour and changes in metabolism that alter the concentrations of antiepileptic drugs. One-third of women with epilepsy will have an increase in seizure frequency during pregnancy. Ten to twenty percent will have a decrease in seizure frequency. A small number of women will have one or two seizures during pregnancy and never have them at any other time in their life. (7) Majority of the women with epilepsy will not have their seizure frequency altered. Studies show that changes in seizure frequency do not depend on the seizure type, age of the mother, duration of epilepsy or the number of seizures that occurred in a previous pregnancy. In general, it is believed that most seizures will occur toward the end of the pregnancy; however, one-third of seizures can occur in the first trimester. A small percentage of women will have a permanent increase in their seizure frequency following pregnancy. A recent evaluation of previous studies found no clear evidence to state if seizures were increased or decreased in general in pregnant women with epilepsy.

In the current study, seizure disorder was the most common cause of neurological referral of a pregnant patient in our institute. There is a wide range of variability of incidence of seizure in pregnancy in various studies conducted in India. [1-6]

This variation may be attributed to the facilities available at the centre for neurological care or number of cases referred from a gynaecological centre.

In our study, patients aged between 21-25 years of age had higher incidence of seizure disorder.

In our study most of the patients with seizures were in second trimester (41%) followed by patients in third trimester (35.4%), which is in contrast to previously published studies that showed a higher incidence of seizures in the third trimester as depicted in Table 5. [6,8] In a study by Gupta et al, [2] there was higher incidence of seizures in second trimester and postpartum. Most seizures occur towards the end of the pregnancy; however, one-third of seizures can occur in the first trimester. [9] In the current study, 38.7% had new-onset seizure during pregnancy. Rest of the patients had prior history of seizure disorder, of which 32.2% were already on AEDs and had seizures despite being compliant with therapy. These results were in accordance with study conducted by Gupta et al. [2]

There were limited studies available to evaluate incidence of cerebrovascular disorders in pregnancy and there is wide variability in the data available. In three population based studies, the incidence of all types of stroke ranged from four-to-seven cases per 100,000 pregnancies. However, data from the National Inpatient Sample of the Healthcare Cost and Utilisation Project suggest that the incidence of pregnancy associated stroke has risen since the 1990s. These data estimate the incidence of all types of pregnancy associated stroke to be 25 to 34 per 100,000 deliveries. Table 6 depicts the incidence of stroke in pregnancy in various studies.

In the present study 35.8% patients presented with cerebrovascular disorders, of which 12.5% were ischaemic stroke, 8.3% were haemorrhagic stroke, 25% had CSVT and 54.1% had PRES.

Postpartum angiopathy is one of several conditions included in the spectrum of the Reversible Cerebral Vasoconstriction Syndromes (RCVS).18 Postpartum angiopathy is characterised by severe headaches and reversible narrowing of intracerebral arteries, often complicated by seizures, reversible brain oedema, lobar haemorrhage, convexity (non-aneurysmal) subarachnoid haemorrhage and ischaemic strokes. Postpartum angiopathy is a non-inflammatory, vasoconstrictive condition. Approximately, one-third of patients with postpartum angiopathy are noted to have reversible cerebral oedema and clinical features (Headaches, Seizures), which are very similar to patients with PRES and more than half the patients with PRES show evidence of cerebral artery narrowing on vascular imaging. Hence, postpartum angiopathy and PRES are considered overlapping conditions. In our study, there were two patients who presented with ischaemic stroke. Intracranial haemorrhage is a rare, but serious disorder that accounts for approximately 1% of ICU admissions and carries a mortality of 40% to 70%. Common causes include hypertensive intracerebral haemorrhage, ruptured berry aneurysm, arteriovenous malformation, eclampsia, anticoagulant toxicity, bleeding disorders and (rarely) bleeding into a brain tumour or cocaine use. The relative risk of intracerebral haemorrhage during pregnancy and the 6 weeks after pregnancy was 5.6 times that for non-pregnant patients. The relative risk of bleeding during pregnancy was 2.5 (95% confidence interval, 1.0-6.4) and increased to 18.2 (95% confidence interval, 8.7-38.1) in the immediate postpartum period.15 Subarachnoid haemorrhage occurs in one to two per 10,000 pregnancies. There is a three-fold increased risk of subarachnoid haemorrhage during pregnancy and 85% of subarachnoid haemorrhages occur in the second or third trimester. [19,20]

The risk of bleeding continues into the puerperal period. Theoretical explanations for the increased risk of haemorrhage during pregnancy include an increase in blood volume, stroke volume and cardiac output. Hormone-induced vasodilatation and changes in the vessel wall structure have also been suggested as contributory mechanisms. [15] Straining during labour would seem to make this a particularly high risk period, but surprisingly only few aneurysms bleed during labour. [15]

Cerebral venous thrombosis traditionally has been associated with pregnancy and it accounted for 12% of all cases in a series of 624 patients in a large International cohort. There may be some geographic differences in the incidence of cerebral venous thrombosis. In a series of 49 Taiwanese patients with stroke during pregnancy, Jeng et al [12] found that 11 (22%) had cerebral venous sinus thrombosis. In contrast, there was only one case of cerebral venous sinus thrombosis in a series of 31 patients with pregnancy-related stroke reported by Kittner et al from the United States. [15] In a series of 754 obstetric patients admitted to the ICU of the King Edward Memorial Hospital in Mumbai, India, over a 10-year period, 26 admissions (3.5%) were for cerebral venous sinus thrombosis. [21] Table 7 shows incidence of cerebral sinus thrombosis in various studies. There is 120% to 300% increase in circulating levels of clotting factors during pregnancy. Levels of factor II, VII and X are also increased. The level of protein S is decreased, but that of protein C remains unchanged. These changes along with an inhibited fibrinolytic system result in a marked increase in fibrin generation during pregnancy and puerperium. This hypercoagulable state along with conditions resulting in dehydration during labour and puerperium may be responsible for thrombotic complications in pregnancy including cerebral venous thrombosis. Risk factors associated with pregnancy-related cerebral venous sinus thrombosis are maternal age, hyperemesis, delivery by caesarean section, intercurrent infection and maternal hypertension. In a recent report, Jeng et al [12] noted that 64% of their 11 patients with pregnancy associated cerebral venous thrombosis were in a hypercoagulable state: four had protein S deficiency, one had protein C deficiency and one each had systemic lupus erythematosus and antiphospholipid syndrome. Only a small proportion of patients develop cerebral venous sinus thrombosis during pregnancy, and 66% to 80% of cases occur during puerperium. Headache is the commonest symptom of cerebral venous thrombosis and occurs in 95% of patients. Other manifestations include focal seizures (47%), paresis (43%), papilloedema (41%), altered consciousness (39%), and isolated intracranial hypertension (20%). The diagnosis is made by CT or MR Venogram.

Posterior Reversible Encephalopathy Syndrome (PRES) is a constellation of neurological signs and symptoms associated with Magnetic Resonance Imaging (MRI) findings of hyperintensity and oedema on T2 weighted images, mainly in the occipital parietal lobes. While PRES has been seen with a variety of clinical conditions such as eclampsia, hypertensive encephalopathy, immunosuppression and liver failure. The clinical presentation and imaging findings appear to be similar regardless of the underlying disease.

The obstetric literature on PRES has been limited to cases/ case series with the largest patient series (n= 46) describing the relationship between eclampsia and PRES. Brewer and colleagues [22] reported that among patients with PRES, headache was the most common symptom (87.2%) followed by altered mental status (51.1%) and visual disturbances (34%). In a study by Nelli Fisher et al, [23] while a headache was present in all preeclamptic patients with PRES. In the present study, there were thirteen patients that were diagnosed with PRES. All of them presented with features of preeclampsia. All patients had headache and elevated blood pressures at the time of admission. Ten patients had seizures. Visual symptoms were present in nine cases and six patients presented with altered sensorium. Imaging showed presence of oedema in occipital regions.

Gliomas are the commonest tumours in pregnant patients and account for 38% of all primary brain tumours followed by meningiomas (28%) and acoustic neuromas (14%). Most brain tumours expand considerably during pregnancy and often manifest for the first time in pregnant patients. Peritumoral oedema can worsen as a result of a generalised increase in intracellular and extracellular fluid compartments in the late second and third trimesters. [24] Headache, vomiting, visual symptoms, focal neurologic deficits and seizures are common symptoms of primary brain tumours.

In our study three patients had tumours. One patient presented with facial nerve palsy in the postpartum period. Imaging was suggestive of glioma. Patient was successfully operated and her post-operative recovery was uneventful. Second case was glioblastoma, diagnosed during 2nd trimester and she presented with headache, vomiting and altered sensorium.

Third case was diagnosed as cutaneous neurofibromatosis. She had multiple neurofibromas all over the body which appeared in first pregnancy and the size, number of lesions increased in second pregnancy. There is a possible role of oestrogens in the appearance and growth of neurofibroma in pregnancy.

The most common movement disorders encountered in pregnancy include Restless Legs Syndrome (RLS), Chorea Gravidarum (CG), Parkinson's Disease (PD), Essential Tremor (ET) and Huntington's Disease (HD). Chorea gravidarum is a generic term for chorea of any cause starting during pregnancy. CG begins after the first trimester in half of patients, spontaneously abates in approximately one-third before delivery and resolves as the pregnancy progresses and may recur in 1 in 5 women in subsequent pregnancies. [25] Maternal and foetal risks are not elevated.

In the present study, 3 cases presented with chorea. Two patients were diagnosed with chorea gravidarum. Another case was diagnosed as Wilson's disease. Our study findings are similar to other studies as shown in Table 8.

An increase in the incidence of idiopathic facial palsy during pregnancy and postpartum period was found in previous studies. [26] Prognosis is excellent and similar to that observed in non-pregnant patients. Sarella et al [8] reported one case of facial nerve palsy during third trimester of pregnancy. Raymond L Hilsinger, Jr. and Kedar Karim et al [27] reported 42 cases of Bell's palsy during pregnancy. Of the 42 cases in pregnancy 31 occurred in the third trimester, five in the first two weeks postpartum and six in the first two trimesters. In our study, three patients presented with facial nerve palsy. One patient presented during the postpartum period and had bilateral facial nerve palsy, whose CSF and imaging findings were normal. Two cases presented in second trimester had unilateral LMN facial palsy. All the three patients recovered completely. Guillain-Barre syndrome affects 6-24/100,000 of population during pregnancy.

Incidence in pregnancy is not greater than expected in non-pregnant women of child bearing age. [28] GB syndrome is known to worsen during the postpartum period due to increase in delayed hypersensitivity relapses during subsequent pregnancies can occur. Pregnancy, labour and delivery proceed normally for most women. Both plasmapheresis and immunoglobulins were used with good maternal and foetal outcome. In our study, three patients were diagnosed with GBS. All had AIDP, one case presented during second trimester and two cases during postpartum period. All three patients improved spontaneously.

CONCLUSION

Many different neurological conditions may be encountered during pregnancy. Epilepsy and cerebrovascular disorders emerge as the predominant neurological disorders during pregnancy and puerperium. Effects of these conditions on pregnancy and the effects of pregnancy on the course of these disorders should be kept in mind when dealing with these conditions in pregnancy.
