Are symptoms of ‘hypoglycemia’ in Chronic Fatigue Syndrome (CFS) associated with hypoglycemia or orthostatic intolerance in young people?

Background: Symptoms of nausea, feeling faint, malaise and mild anxiety are common in young people with CFS and popularly attributed to ‘hypoglycemia’ resulting in various dietary interventions with little reported improvement.

Objectives: To determine whether the symptoms are associated with measured hypoglycaemia using continuous tissue glucose monitoring or whether these symptoms are associated with documented orthostatic intolerance.

Methods: Nine young people with CFS (mean age 20 years) and mean duration of 4.5 years with persistently troublesome symptoms were compared with 10 healthy adult controls without diabetes. Each subject agreed to 3 days Continuous Glucose Monitoring System (Medtronic CGMS). This is routinely used in adolescent diabetics to document food intake, tissue glucose levels and activity levels to monitor control.

Subsequently 8 of these had formal cardiac tilt table testing where heart rate and blood pressure are measured supine and during 70 degree head-up tilt for up to 10 minutes to assess the presence orthostatic intolerance (either postural orthostatic tachycardia (POTS) or neurocardiogenic hypotensive syndrome). If positive, appropriate medical management of increasing salt and fluids, gentle improvement of muscle tone and blood pressure support medications, was implemented.

Results: The tissue glucose was calibrated with the blood glucose and all fell within acceptable normal range. There was statistical (but not clinical) significance in average tissue glucose in CFS subjects. 6% of time in controls and 16.8% in CFS was spent in the range <4mmol/L glucose (95% CI -23% to +2%, p=0.1) suggesting weak evidence for a difference given the variability and small sample size. The reported presence of symptoms throughout the day was not associated with significant reduction in tissue glucose levels.

Six had confirmed evidence for POTS, one for neurocardiogenic syndrome and one for a combination of both. All 8 reported improvement in all symptoms especially nausea, dizziness and malaise with active treatment of their orthostatic intolerance.

Conclusion: This study could not confirm a link between putative symptoms of ‘hypoglycemia’ and documented hypoglycemia. This suggests that symptoms frequently attributed to ‘hypoglycemia’ may be due to orthostatic intolerance and further investigation and management of this condition provides more reported relief for these troublesome symptoms.

Cervical spine stenosis as a cause of severe ME/CFS and orthostatic intolerance symptoms

Background: Comparatively little has been published on the clinical features and management of severe forms of ME/CFS.

Objectives: To describe the presenting symptoms and neurological examination findings in three young adult women whose disabling ME/CFS symptoms and orthostatic intolerance improved after the recognition and surgical management of cervical spine stenosis (CSS).

Methods: This retrospective case series includes three consecutive individuals who (1) met the Fukuda and criteria for CFS, (2) had evidence of refractory orthostatic intolerance, (3) were unable to work or attend school, and (4) were minimally responsive to medical and psychiatric management. To investigate pathological reflex findings, all underwent MRI evaluations. CSS was considered present if the AP cervical spinal canal diameter (SCD) was less than 10 mm at any level. Overall function was assessed before and after cervical disc replacement surgery using (1) a clinician-assigned Karnofsky score (range 0 to 100) and (2) the SF-36 physical function (PF) subscale score (range 10-30). Higher scores indicate better function on both measures.

Results: Age at onset of symptoms was 12, 29, and 29 years. The onset of ME/CFS was acute in all three. Neurological exam findings included > 3+ (brisk) deep tendon reflexes (DTR) in 2/3, positive Hoffman sign in 2/3, tremor in 2/3, and absent gag reflex in 1/3. Diagnosis was delayed for 6-9 years after the onset of symptoms. Brain MRIs were normal. The youngest patient had congenital CSS with a single level disc protrusion at C5-6 that caused further ventral cord compression and a SCD of 7 mm. Her mother also has cervical stenosis. A second
patient had two disc protrusions at C5-6 and C6-7 with SCD of 7 and 9 mm, and myelomalacia (this patient has a sibling with Chiari I malformation). The third had acquired CSS due to a single level disc bulge at C5-6 (SCD = 8.5 mm).

Improvements were evident within 2 months of single-level cervical disc replacement surgery (one patient also had fusion at an adjacent level). After 16-40 months of follow-up, all reported improved fatigue, cognitive dysfunction, PEM, lightheadedness, and anxiety. The pre- to post-op SF-36 PF scores improved from 13 to 30, 18 to 30, and 16 to 26, respectively, and the Karnofsky scores improved from 40 to 90, 40 to 90, and 50 to 100, respectively. Standing tests conducted at variable intervals from pre- to post-op showed a reduction in the maximal heart rate (HR) change during 5 minutes of standing from 64 to 22 bpm, 42 to 29 bpm, and 34 to 27 bpm, respectively.

Conclusion: This case series draws attention to the potential for CSS to contribute to ME/CFS and orthostatic symptoms, extending work by Heffez in fibromyalgia (Eur Spine J 2004;13:516). Further work is needed to define indications for surgery. However, the improvements in HR and function following surgery emphasize the importance of detecting and treating CSS, especially in the subset of those with ME/CFS whose severe symptoms are refractory to other interventions.

Clinical impact of B-cell depletion with the anti-CD20 antibody rituximab in chronic fatigue syndrome: a preliminary case series

Abstract:

BACKGROUND: Chronic fatigue syndrome (CFS) is a disease of unknown aetiology. A patient with CFS had unexpected, marked recovery of CFS symptoms lasting for five months during and after cytotoxic chemotherapy for Hodgkin’s disease. We reasoned that the transient CFS recovery was related to methotrexate treatment, which induces immunomodulation in part through B-cell depletion.

METHODS: In a case series, this patient and two additional CFS patients were B-cell depleted by infusion of the monoclonal anti-CD20 antibody rituximab.

RESULTS: All three had improvement of all CFS symptoms. Patients 1 and 2 had major amelioration from 6 weeks after intervention, patient 3 slight improvement from the same time, but then improved markedly from 26 weeks after intervention. The symptomatic effect lasted until weeks 16, 18 and 44, respectively. At relapse, all were retreated with a single (patient 1) or double rituximab infusion (patients 2 and 3). Again, all three had marked symptom improvement, mimicking their first response. After new symptom recurrence, patients 1 and 2 were given weekly oral methotrexate, patient 1 having effect also from this agent. Patients 1 and 2 were again treated for a third rituximab infusion after new relapse, again with a marked clinical benefit. No unexpected toxicity was seen.

CONCLUSION: These observations suggest that B-lymphocytes are involved in CFS pathogenesis for a subset of patients. Benefit for all CFS symptoms, the delayed symptom relief following B-cell depletion, the kinetics of relapses, and the effect also from methotrexate treatment, provide suggestive evidence that B-cells play a significant role in the ongoing clinical features, and that CFS may be amenable to therapeutic interventions aimed at modifying B-cell number and function. More systematic investigations of this therapeutic strategy, and of its biological basis, are now needed.

Association of chronic fatigue syndrome and acute psychotic episode: is it coincidental?

Sir: We present a case of a woman who had suffered from chronic fatigue syndrome (CFS) for several years and was admitted for an acute psychotic episode. This association has rarely been described.

Case report. Ms. A, a 43-year-old mother of 2 children, was admitted in January 2006 with delusion and hallucinations following a period of exacerbated fatigue. She was afraid that her children would be abducted by the devil and tried to protect them. She begged her children not to get near the walls of her house for fear that the devil could erupt from the walls and take them.

Ms. A first experienced persistent fatigue 3 years before admission. Prior to this, she had been a very active woman. She had to stop working and was able to participate in only very few activities during the day. She attributed her fatigue to the overwhelming task of educating her hyperkinetic 9-year-old son.

She had a depressive episode of several months’ duration 10 years before admission, following an abortion of a pregnancy involving a malformed child. This episode had subsided without relapse. She had infectious mononucleosis 20 years before admission. A polysomnographic test 2 years before admission showed many awakenings interrupting Ms. A’s sleep pattern. She was then diagnosed with chronic fatigue syndrome according to the criteria of Holmes1 and Fukuda.2 Antidepressive medication was prescribed; it alleviated the secondary depressive symptoms but had no impact on her fatigue complaint.

During Ms. A’s hospitalization, her blood analysis results were unremarkable, excluding common organic causes of fatigue. Results of her neurologic examination at admission were normal. Her brain computed tomography (CT) scan showed frontal cortical atrophy, but neuropsychological tests failed to show major cognitive impairments.

Olanzapine was prescribed at the dosage of 15 mg/day, and her symptoms gradually subsided. She was discharged 1 month after admission, totally free of her psychotic symptoms. Her neuroleptic treatment was changed to 10 mg of aripiprazole because of excessive weight gain. Aripiprazole was as effective as olanzapine but allowed her to return to her usual weight. The treatment was gradually stopped after 1 year, with no recurrence of psychotic symptoms.

The association between CFS and psychosis has rarely been described. We are aware of only 2 other case reports. The first describes a 28-year-old man who developed CFS after mononucleosis and suffered afterward from a manic episode with psychotic characteristics.3

Chronic fatigue syndrome and complement activation

Abstract:

This report describes a case of chronic fatigue syndrome (CFS) that followed a well-documented episode of acute Epstein-Barr virus (EBV) mononucleosis. All aetiological tests for chronic fatigue were found to be negative or normal, as were immunological tests. After 2 years of chronic fatigue following the acute illness, measurements of complement split products were performed to test for complement activation. These were positive and remained positive for 14 months, after which the patient then recovered from CFS.

Chronic fatigue syndrome with autoantibodies–the result of an augmented adjuvant effect of hepatitis-B vaccine and silicone implant

Abstract:

BACKGROUND: Chronic fatigue syndrome (CFS) that defines by prolonged fatigue and other manifestations, was recently integrated into a spectrum of central sensitivity syndromes including several diseases as fibromylagia. CFS etiology is multi-factorial commonly triggered by infectious agents. Vaccines, induce an immune response similarly to infections, and may trigger just like infections autoimmune diseases, CFS and fibromyalgia. Furthermore vaccines contain an adjuvant which enhances their immune stimulation.

CASE PRESENTATION: A 56-year-old woman was diagnosed with CFS accompanied by fibromyalgia, demyelination and autoantibodies. Her illness begun following the 2nd dose of hepatitis-B vaccine, and was aggravated by the 3rd vaccination. She underwent silicone breast implantation 6 years before vaccination with no adverse events. However, between the 2nd and 3rd vaccination she suffered a breast injury with local inflammation. Upon explanation of her breast implants silicone leak was observed.

DISCUSSION: Vaccines have been reported to precede CFS mainly following exposure to multiple vaccinations (e.g. the Gulf war syndrome), or as an adverse response to the vaccine adjuvant (e.g. the macrophagic myofasciitis syndrome). Silicone is considered an adjuvant to the immune system, and may induce “the adjuvant disease”. Silicone implant, especially silicone leak relationship with autoimmunity and CFS has been the focus of considerable debates.

CONCLUSION: Our patient illness started following hepatitis-B vaccine, suggesting that it was caused or accelerated by vaccination. In parallel to vaccination our patient suffered from breast injury, which might represent the time of silicone leak. The exposure to the adjuvant, silicone, might have augmented her immune response to the vaccine. To the best of our knowledge this is the first case of combined adverse effect to vaccine and silicone. Vaccine safety in individuals with silicone implants requires further studies.

Obstructions for quality care experienced by patients with chronic fatigue syndrome (CFS)–a case study

Abstract:

OBJECTIVE: To explore obstructions for quality care from experiences by patients suffering from chronic fatigue syndrome (CFS).

METHODS: Qualitative case study with data drawn from a group meeting, written answers to a questionnaire and a follow-up meeting. Purposeful sample of 10 women and 2 men of various ages, recruited from a local patient organization, assumed to have a special awareness for quality care.

RESULTS: CFS patients said that lack of acknowledgement could be even worse than the symptoms. They wanted their doctors to ask questions, listen to them and take them seriously, instead of behaving degrading. Many participants felt that the doctors psychologized too much, or trivialized the symptoms. Participants described how doctors’ lack of knowledge about the condition would lead to long-term uncertainty or maltreatment. Even with doctors who were supportive, it would usually take months and sometimes years until a medical conclusion would be reached, or other disorders were ruled out. Increased physical activity had been recommend, but most of the informants experienced that this made them worse.

CONCLUSION: Current medical scepticism and ignorance regarding CFS shapes the context of medical care and the illness experiences of CFS patients, who may feel they neither get a proper assessment nor management.

PRACTICE IMPLICATIONS: CFS patients’ reports about patronizing attitudes and ignorance among doctors call for development of evidence based strategies and empowerment of patients, acknowledging the patients’ understanding of symptoms and the complex nature of the disease. The NICE guidelines emphasize the need of patient participation and shared decision-making.

Normalization of the increased translocation of endotoxin from gram negative enterobacteria (leaky gut) is accompanied by a remission of chronic fatigue syndrome

Abstract:

There is now evidence that chronic fatigue syndrome (CFS) is accompanied by an increased translocation of endotoxins from gram-negative enterobacteria through the gut wall, as demonstrated by increased prevalences and median values for serum IgM and IgA against the endotoxins of gram-negative enterobacteria. This condition can also be described as increased gut permeability or leaky gut and indicates intestinal mucosal dysfunction (IMD).

Here we report a case of a 13 year old girl with CFS who showed very high values for serum IgM against the LPS of some enterobacteria and signs of oxidative and nitrosative stress, activation of the inflammatory response system, and IgG3 subclass deficiency. Upon treatment with specific antioxidants and a “leaky gut diet”, which both aim to treat increased gut permeability, and immunoglobins intravenously, the increased translocation of the LPS of gram negative enterobacteria normalized and this normalization was accompanied by a complete remission of the CFS symptoms.

Chronic fatigue syndrome in a 15-year-old girl

Abstract:

Fatigue and lack of energy are frequent symptoms in children and adolescents. A diagnosis of chronic fatigue syndrome should be considered in children and adolescents who complain of chronic fatigue associated with other symptoms without a demonstrable physical cause. Lack of knowledge about this syndrome and late diagnosis may have a negative impact on the normal development of affected children and adolescents. Treatment should be based on a rehabilitation program with cognitive behavioral therapy and a gradual increase in activities.
