Pituitary dysfunction after aneurysmal subarachnoid haemorrhage: Course and clinical predictors-the HIPS study

Objective We describe the occurrence and course of anterior pituitary dysfunction (PD) after aneurysmal subarachnoid haemorrhage (SAH), and identify clinical determinants for PD in patients with recent SAH. Methods We prospectively collected demographic and clinical parameters of consecutive survivors of SAH and measured fasting state endocrine function at baseline, 6 and 14 months. We included dynamic tests for growth-hormone function. We used logistic regression analysis to compare demographic and clinical characteristics of patients with SAH with and without PD. Results 84 patients with a mean age of 55.8 (±11.9) were included. Thirty-three patients (39%) had PD in one or more axes at baseline, 22 (26%) after 6 months and 6 (7%) after 14 months. Gonadotropin deficiency in 29 (34%) patients and growth hormone deficiency (GHD) in 26 (31%) patients were the most common deficiencies. PD persisted until 14 months in 6 (8%) patients: GHD in 5 (6%) patients and gonadotropin deficiency in 4 (5%). Occurrence of a SAH-related complication was associated with PD at baseline (OR 2.6, CI 2.2 to 3.0). Hydrocephalus was an independent predictor of PD 6 months after SAH (OR 3.3 CI 2.7 to 3.8). PD was associated with a lower score on health-related quality of life at baseline (p=0.06), but not at 6 and 14 months. Conclusions Almost 40% of SAH survivors have PD. In a small but substantial proportion of patients GHD or gonadotropin deficiency persists over time. Hydrocephalus is independently associated with PD 6 months after SAH. Trial registration number NTR 2085.

DIFFERENCES IN COGNITIvE AND EMOTIONAl OUTCOMES bETwEEN PATIENTS wITH PERIMESENCEPHAlIC AND ANEURySMAl SUbARACHNOID HAEMORRHAGE

OBJECTIVES To compare cognitive and emotional outcomes between patients with aneurysmal and perimesencephalic subarachnoid haemorrhage and norm scores. DESIGN First measurement in prospective cohort study. PATIENTS Sixty-seven patients with subarachnoid haemorrhage, were divided into perimesencephalic (n = 8) and aneurysmal (n = 59) subarachnoid haemorrhage groups. METHODS Patients completed several questionnaires within the first year after haemorrhage. Depression was measured with the Center for Epidemiologic Studies Depression scale, fatigue with the Fatigue Severity Scale, and objective cognitive functioning with the Trail Making Test. Glasgow Coma Scale scores were collected at hospital admission. RESULTS Perimesencephalic patients had lower depression (p = 0.006) and lower fatigue scores (p = 0.029) and were faster on the Trail Making Test A (p = 0.002) than aneurysmal patients. No differences between the groups were found on Trail Making Test B (p = 0.112) and presence of fatigue (p = 0.105). Compared with norm scores, aneurysmal patients scored significantly worse on all outcomes, whereas perimesencephalic patients scored worse on Trail Making Test B (p < 0.008), fatigue (p = 0.073) and presence of fatigue (p = 0.058). CONCLUSION Perimesencephalic patients may experience problems in complex cognitive functioning and fatigue. In this respect, they have similar sequelae as aneurysmal patients, which may interfere with daily activities and social participation. These findings are of clinical relevance, as perimesencephalic patients often are discharged from hospital without long-term follow-up.

Long-Term Functioning of Patients with Aneurysmal Subarachnoid Hemorrhage: A 4-yr Follow-up Study.

ObjectivesThe aim was to study changes over time for multiple outcomes based on the International Classification of Functioning, Disability, and Health in patients with aneurysmal subarachnoid hemorrhage and to compare long-term outcomes with norms. DesignA prospective cohort study with 4-yr follow-up was conducted. Main outcome measures were as follows: Center for Epidemiologic Studies–Depression Scale, Fatigue Severity Scale, Trail Making Test A and B, Barthel Index, Sickness Impact Profile-68, Impact on Participation and Autonomy Questionnaire, Social Support List-12, Multidimensional Health Locus of Control Scales, COOP-WONCA Charts, and Short Form-36 Health Survey. ResultsSeventy-six patients with aneurysmal subarachnoid hemorrhage were included. Measurements were done at T1 = 0.4 yrs (SD, 0.3 yrs) and T2 = 3.9 yrs (SD, 0.7 yrs) after onset. Significant improvements over time were found for Barthel Index (T1 = 18.5; T2 = 19.5; P = 0.023), Trail Making Test B (T1 = 119.4; T2 = 104.6; P = 0.025), Social Support List-12 total score (T1 = 31.1; T2 = 32.7; P = 0.042) and esteem support (T1 = 10.2; T2 = 10.9; P = 0.027), Multidimensional Health Locus of Control Scales (physician-orientation) (T1 = 21.8; T2 = 19.2; P = 0.020), and Short Form-36 Health Survey (role-emotional) (T1 = 54.6; T2 = 73.9; P = 0.048). Center for Epidemiologic Studies–Depression Scale, Fatigue Severity Scale, Sickness Impact Profile-68, and Short Form-36 Health Survey scores remained stable over time. A decline was found for COOP-WONCA (overall-health) (T1 = 2.3; T2 = 2.7; P = 0.021). At 4-yr follow-up, proportions of depression (27%) and fatigue (60%) were larger and scores on the Fatigue Severity Scale (mean [SE], 4.3 [0.2]), Trail Making Test A (mean [SE], 51.3 [3.9]), and Trail Making Test B (mean [SE], 104.4 [0.2]) were significantly worse than norm scores. ConclusionsMany patients with aneurysmal subarachnoid hemorrhage had fairly good long-term outcomes, but problems in executive functioning, mood, and fatigue still exist at long-term follow-up.

Hypopituitarism after subarachnoid haemorrhage, do we know enough?

BackgroundFatigue, slowness, apathy and decrease in level of activity are common long-term complaints after a subarachnoid haemorrhage (SAH). They resemble the symptoms frequently found in patients with endocrine dysfunction. Pituitary dysfunction may be the result of SAH or its complications. We therefore hypothesized that it may explain some of the long-term complaints after SAH.We reviewed the literature to clarify the occurrence, pattern and severity of endocrine abnormalities and we attempted to identify risk factors for hypopituitarism after SAH. We also assessed the effect of hypopituitarism on long-term functional recovery after SAH.MethodsIn a MEDLINE search for studies published between 1995 and 2014, we used the term subarachnoid haemorrhage in combination with pituitary, hypopituitarism, growth hormone, gonadotropin, testosterone, cortisol function, thyroid function and diabetes insipidus. We selected all case-series and cohort studies reporting endocrine function at least 3 months after SAH and studied their reported prevalence, pathogenesis, risk factors, clinical course and outcome.ResultsWe identified 16 studies describing pituitary function in the long term after SAH. The reported prevalence of endocrine dysfunction varied from 0 to 55% and the affected pituitary axes differed between studies. Due to methodological issues no inferences on risk factors, course and outcome could be made.ConclusionsNeuroendocrine dysfunction may be an important and modifiable determinant of poor functional outcome after SAH. There is an urgent need for well-designed prospective studies to more precisely assess its incidence, clinical course and effect on mood, behaviour and quality of life.

The relationship of coping style with depression, burden, and life dissatisfaction in caregivers of patients with subarachnoid haemorrhage.

OBJECTIVE To assess the relationship of coping style with depression, burden and life satisfaction in caregivers of patients with subarachnoid haemorrhage. DESIGN Cross-sectional study. PARTICIPANTS Forty-one primary caregivers of patients with subarachnoid haemorrhage. METHODS Caregivers completed several questionnaires within the first year after subarachnoid haemorrhage. Coping style was assessed using the Utrecht Coping List, depression with the Goldberg Depression Scale (GDS), burden with the Sense of Competence Questionnaire, and life satisfaction with the Life Satisfaction Questionnaire. RESULTS Caregivers had a mean burden score of 37.8 (standard deviation (SD) = 7.4) and a life satisfaction score of 5.0 (SD = 0.6). Nine caregivers (23%) had depressive symptoms (GDS ≥ 2). A palliative coping style was positively associated with the presence of depressive symptoms (odds ratio (OR) = 1.45, p = 0.016). A passive coping style was positively related to burden (ß = 1.61, p = 0.024), adjusted for morbidity of the caregiver (ß = 11.90, p = 0.013), and inversely related to life satisfaction (ß = -0.10, p = 0.025). CONCLUSION In caregivers of patients with subarachnoid haemorrhage palliative or passive coping styles are related to depressive symptoms, higher burden and life dissatisfaction. This implies that rehabilitation programmes for patients with subarachnoid haemorrhage should also include caregiver support programmes that focus on coping style.

Long-term fatigue after perimesencephalic subarachnoid haemorrhage in relation to cognitive functioning, mood and comorbidity

Abstract Purpose: To study relationships between fatigue and objective and subjective cognitive functioning, mood and comorbidity in the long term after perimesencephalic subarachnoid haemorrhage (PM-SAH). Methods: Cross-sectional study. Objective cognitive functioning was measured with: Trail Making Test; Symbol Substitution; D2; Verbal and Semantic Fluency; Tower Test; Digit Span; 15-Words Test; Rey Complex Figure. Subjective cognitive functioning: Cognitive Failure Questionnaire. Fatigue: Fatigue Severity Scale. Mood: Hospital Anxiety and Depression Scale. Results: Forty-six patients, mean age 50.4 (SD = 9.4), mean time after PM-SAH 4.7 (SD = 1.6) years participated. Patients with fatigue (33%) had significantly lower scores than patients without fatigue on most objective cognitive functioning tests (p < 0.05). Fatigue score was significantly associated with subjective and objective cognitive functioning, mood and comorbidity. After adjustment for mood and comorbidity, fatigue remained associated with attention and executive functioning. Conclusions: This study supports our previous findings that a third of patients with PM-SAH experience fatigue and problems of cognitive functioning, also in the long term. Future research should investigate whether these patients would benefit from long-term follow-up and/or cognitive rehabilitation programmes. Implications for Rehabilitation Consequences for patients with PM-SAH are underestimated. One in every three patients suffered from fatigue in the long term after onset of PM-SAH. Patients with PM-SAH should be screened for problems of cognitive functioning, fatigue and mood in outpatient clinic just as patients with aneurysmal SAH.

Impaired cardiorespiratory fitness after aneurysmal subarachnoid hemorrhage.

OBJECTIVE To assess cardiorespiratory fitness in patients following an aneurysmal subarachnoid haemorrhage and to explore this in fatigued and non-fatigued patients. DESIGN Cross-sectional case-control study. SUBJECTS/PATIENTS A total of 28 patients, 6 months post aneurysmal subarachnoid haemorrhage, and 28 sex- and age-matched controls. METHODS Cardiorespiratory responses to a progressive cardiopulmonary exercise test on a cycle ergometer were obtained using indirect calorimetry. Fatigue was assessed using the Fatigue Severity Scale. RESULTS Mean peak oxygen uptake (V̇O2peak) was significantly lower in patients (22.0 (standard deviation (SD) 6.2) ml/kg/min) than in controls (69% of controls, p < 0.001). All other cardiorespiratory fitness parameters were also lower, with peak levels ranging from 62% to 77% of matched controls. Mean V̇O2peak was 19.4 (SD 4.1) ml/kg/min in fatigued patients (63% of matched controls, p < 0.001) and 23.9 (SD 6.9) ml/kg/min in non-fatigued patients (74% of matched controls, p = 0.002). CONCLUSION Cardiorespiratory fitness is impaired after aneurysmal subarachnoid haemorrhage, both in fatigued and non-fatigued patients. This finding may have implications for treatment.

Impaired muscle strength may contribute to fatigue in patients with aneurysmal subarachnoid hemorrhage

Patients with aneurysmal subarachnoid hemorrhage (a-SAH) show long-term fatigue and face difficulties in resuming daily physical activities. Impaired muscle strength, especially of the lower extremity, impacts the performance of daily activities and may trigger the onset of fatigue complaints. The present study evaluated knee muscle strength and fatigue in patients with a-SAH. This study included 33 patients, 6 months after a-SAH, and 33 sex-matched and age-matched healthy controls. Isokinetic muscle strength of the knee extensors and flexors was measured at 60 and 180°/s. Maximal voluntary muscle strength was defined as peak torque and measured in Newton-meter. Fatigue was examined using the Fatigue Severity Scale. In patients with a-SAH, the maximal knee extension was 22% (60°/s) and 25% (180°/s) lower and maximal knee flexion was 33% (60°/s) and 36% (180°/s) lower compared with that of matched controls (P⩽0.001). The Fatigue Severity Scale score was related to maximal knee extension (60°/s: r=−0.426, P=0.015; 180°/s: r=−0.376, P=0.034) and flexion (60°/s: r=−0.482, P=0.005; 180°/s: r=−0.344, P=0.083). The knee muscle strength was 28–47% lower in fatigued (n=13) and 11–32% lower in nonfatigued (n=20) patients; deficits were larger in fatigued patients (P<0.05), particularly when the muscle strength (peak torque) was measured at 60°/s. The present results indicate that patients with a-SAH have considerably impaired knee muscle strength, which is related to more severe fatigue. The present findings are exploratory, but showed that knee muscle strength may play a role in the severity of fatigue complaints, or vice versa. Interventions targeting fatigue after a-SAH seem necessary and may consider strengthening exercise training in order to treat a debilitating condition.

The Puzzle of Apparent Life-Threatening Events in a Healthy Newborn

Apneic neonatal seizures can present as apparent life-threatening events. We report a newborn with unexplained episodes of apnea associated with cyanosis and desaturation, starting on the first day postpartum. Biochemical tests were normal. Central nervous system infections as well as abnormalities of upper airways and cardiovascular system were excluded. Brain monitoring using amplitude-integrated electroencephalography (aEEG) was inconclusive. Continuous monitoring using video EEG revealed epileptic seizures originating from the left temporal region as the cause of the apneas. Magnetic resonance imaging (MRI) of the brain showed a developmental malformation of the left frontal and temporal lobes. The patient became seizure free after treatment with antiepileptic medication. This report illustrates that brain monitoring using amplitude-integrated EEG alone could miss focal neonatal seizures. When clinical suspicion of apneic seizures is high in infants with apparent life threatening events, multichannel polygraphic video-EEG monitoring is indicated. Prompt diagnosis and treatment can be life saving.
