Chronic fatigue in Ehlers-Danlos syndrome-hypermobile type

Abstract:

Chronic fatigue is an important contributor to impaired health-related quality of life in Ehlers-Danlos syndrome. There is overlap in the symptoms and findings of EDS and chronic fatigue syndrome. A proportion of those with CFS likely have EDS that has not been identified.

The evaluation of chronic fatigue in EDS needs to include a careful clinical examination and laboratory testing to exclude common causes of fatigue including anemia, hypothyroidisim, and chronic infection, as well as dysfunction of major physiological or organ systems.

Other problems that commonly contribute to fatigue in EDS include sleep disorders, chronic pain, deconditioning, cardiovascular autonomic dysfunction, bowel and bladder dysfunction, psychological issues, and nutritional deficiencies.

While there is no specific pharmacological treatment for fatigue, many medications are effective for specific symptoms (such as headache, menstrual dysfunction, or myalgia) and for co-morbid conditions that result in fatigue, including orthostatic intolerance and insomnia.

Comprehensive treatment of fatigue needs to also evaluate for biomechanical problems that are common in EDS, and usually involves skilled physical therapy and attention to methods to prevent deconditioning.

In addition to managing specific symptoms, treatment of fatigue in EDS also needs to focus on maintaining function and providing social, physical, and nutritional support, as well as providing on-going medical evaluation of new problems and review of new evidence about proposed treatments.

Mitochondrial Myopathy in Follow-up of a Patient With Chronic Fatigue Syndrome

Abstract:

Introduction. Symptoms of mitochondrial diseases and chronic fatigue syndrome (CFS) frequently overlap and can easily be mistaken.

Methods. We report the case of a patient diagnosed with CFS and during follow-up was finally diagnosed with mitochondrial myopathy by histochemical study of muscle biopsy, spectrophotometric analysis of the complexes of the mitochondrial respiratory chain, and genetic studies.

Results. The results revealed 3% fiber-ragged blue and a severe deficiency of complexes I and IV and several mtDNA variants. Mother, sisters, and nephews showed similar symptoms, which strongly suggests a possible maternal inheritance. The patient and his family responded to treatment with high doses of riboflavin and thiamine with a remarkable and sustained fatigue and muscle symptoms improvement.

Conclusions. This case illustrates that initial symptoms of mitochondrial disease in adults can easily be mistaken with CFS, and in these patients a regular reassessment and monitoring of symptoms is recommended to reconfirm or change the diagnosis.

Borderline Intracranial Hypertension Manifesting as Chronic Fatigue Syndrome Treated by Venous Sinus Stenting

Abstract:

Chronic fatigue syndrome and cases of idiopathic intracranial hypertension without signs of raised intracranial pressure can be impossible to distinguish without direct measurement of intracranial pressure. Moreover, lumbar puncture, the usual method of measuring intracranial pressure, can produce a similar respite from symptoms in patients with chronic fatigue as it does in idiopathic intracranial hypertension. This suggests a connection between them, with chronic fatigue syndrome representing a forme fruste variant of idiopathic intracranial hypertension. If this were the case, then treatments available for idiopathic intracranial hypertension might be appropriate for chronic fatigue.

We describe a 49-year-old woman with a long and debilitating history of chronic fatigue syndrome who was targeted for investigation of intracranial pressure because of headache, then diagnosed with borderline idiopathic intracranial hypertension after lumbar puncture and cerebrospinal fluid drainage. Further investigation showed narrowings at the anterior ends of the transverse sinuses, typical of those seen in idiopathic intracranial hypertension and associated with pressure gradients.

Stenting of both transverse sinuses brought about a life-changing remission of symptoms with no regression in 2 years of follow-up. This result invites study of an alternative approach to the investigation and management of chronic fatigue.

Chronic fatigue syndrome and non-celiac gluten sensitivity. Association or cause?

To the editor:

In their letter to the editor Response to: Fibromyalgia and chronic fatigue caused by non-celiac gluten sensitivity, Qanneta et al. pose a conceptual problem between the association of chronic fatigue syndrome (CFS) with non-celiac gluten sensitivity (SGNC) from the prevalent conception of considering chronic fatigue as a distinct disease. From this perspective, being chronic fatigue the central disease associated with other processes, they consider NCGS as a comorbid condition and not as an underlying cause.

Response to: fibromyalgia and chronic fatigue syndrome caused by non-celiac gluten sensitivity

Dear Editor:

We have closely read the article published by Isasi et al.1 in Reumatologia Clínica presenting a case of fibromyalgia (FM) and chronic fatigue syndrome (CFS) caused by non-celiac sensitivity to gluten (NGCD). We would like to comment our experience with this attractive topic regarding patients with FM/CFS, which I hope will contribute to an improved knowledge of this association. The authors have reasonably ruled out celiac disease (CD) and have hypothesized that NGCD is the cause of FM and CFS in their patient; upon complete remission (CR) of symptoms, both digestive and musculoskeletal, with a gluten-free diet (GFD).

A case of femoral arteriovenous fistula causing high-output cardiac failure, originally misdiagnosed as chronic fatigue syndrome

Abstract:

Percutaneous arterial catheterisation is commonly undertaken for a range of diagnostic and interventional procedures. Iatrogenic femoral arteriovenous fistulas are an uncommon complication of these procedures. Most are asymptomatic and close spontaneously, but can rarely increase in size leading to the development of symptoms. We report a case of an iatrogenic femoral arteriovenous fistula, causing worsening congestive cardiac failure, in a 34-year-old marathon runner. This was originally diagnosed as chronic fatigue syndrome. Following clinical examination, duplex ultrasound, and CT angiography a significant arteriovenous fistula was confirmed. Elective open surgery was performed, leading to a dramatic and rapid improvement in symptoms. Femoral arteriovenous fistulas have the potential to cause significant haemodynamic effects and can present many years after the initial procedure. Conservative, endovascular, and open surgical management strategies are available.

Lumbar puncture, chronic fatigue syndrome and idiopathic intracranial hypertension: a cross-sectional study

Abstract:

OBJECTIVE: Unsuspected idiopathic intracranial hypertension (IIH) is found in a significant minority of patients attending clinics with named headache syndromes, if it is specifically sought out. Chronic fatigue syndrome is frequently associated with headache. Could the same be true of chronic fatigue? Moreover, there are striking similarities between the two conditions. Could they be related? Attempting to answer these questions, we describe the results of a change in clinical practice aimed at capturing patients with chronic fatigue who might have IIH.

DESIGN: Cross-sectional.

SETTING: Hospital outpatient and radiology departments.

PARTICIPANTS: Patients attending a specialist clinic with chronic fatigue syndrome and headache who had lumbar puncture to exclude raised intracranial pressure.

MAIN OUTCOME MEASURES: Intracranial pressure measured at lumbar puncture and the effect on headache of cerebrospinal fluid drainage.

RESULTS: Mean cerebrospinal fluid pressure was 19 cm H2O (range 12-41 cm H2O). Four patients fulfilled the criteria for IIH. Thirteen others did not have pressures high enough to diagnose IIH but still reported an improvement in headache after drainage of cerebrospinal fluid. Some patients also volunteered an improvement in other symptoms, including fatigue. No patient had any clinical signs of raised intracranial pressure.

CONCLUSIONS: An unknown, but possibly substantial, minority of patients with chronic fatigue syndrome may actually have IIH. An unknown, but much larger, proportion of patients with chronic fatigue syndrome do not have IIH by current criteria but respond to lumbar puncture in the same way as patients who do. This suggests that the two conditions may be related.

A case of lyme disease requiring over 1 year to diagnose at an infectious-disease clinic

Abstract:

A 42-year-old woman presenting with years of fever and vague symptoms could not be satisfactorily diagnosed in physical examination or conventional workups. She was presumptively diagnosed with chronic fatigue syndrome and treated symptomatically. Fourteen months after the initial visit, she developed left facial palsy. Lyme disease serology was positive. Four weeks of oral amoxicillin ameliorated symptoms. Only 5 to 15 cases of Lyme disease are reported annually in Japan, mostly from the northeastern-most island of Hokkaido. It may occur anywhere in Japan, however; probably is underdiagnosed. Lyme disease may cause fevers of unknown origin. Astute clinical suspicion and appropriate workups are thus needed to diagnose this infection.

Fatigue heralding multiple sclerosis

Abstract:

BACKGROUND: Fatigue is a common symptom in multiple sclerosis (MS) and is an important determinant of overall well-being and disability.

OBJECTIVE: To assess the frequency with which fatigue precedes the diagnosis of MS using a retrospective database analysis.

METHODS: Between January 1, 2003 and September 30, 2008, patients diagnosed with fatigue with and without fatigue-related medications within a 3-year period prior to newly diagnosed MS were identified from the MarketScan Databases. All statistical analysis was performed using SAS.

RESULTS: Of the 16,976 patients with MS in the overall population, 5305 (31.3%) were newly diagnosed with MS and had three years of continuous healthcare coverage prior to MS diagnosis. Of these patients, 1534 (28.9%) were labeled with chronic fatigue syndrome (ICD9-780.71) or malaise or fatigue (ICD9-780.79) prior to the diagnosis of MS. One-third of these patients were labeled with fatigue one to two years before the diagnosis; 30.8% were diagnosed only with fatigue and had no other MS symptoms prior to their MS diagnosis. Among the patients diagnosed with fatigue, 10.4% were also prescribed medication for fatigue.

CONCLUSION: This study demonstrates that fatigue may herald MS, often by years. A careful history for transient neurological symptoms and a physical examination is warranted in any patient presenting with fatigue.

Improved chronic fatigue symptoms after removal of mercury in patient with increased mercury concentration in hair toxic mineral assay: a case

Abstract:

Clinical manifestations of chronic exposure to organic mercury usually have a gradual onset. As the primary target is the nervous system, chronic mercury exposure can cause symptoms such as fatigue, weakness, headache, and poor recall and concentration. In severe cases chronic exposure leads to intellectual deterioration and neurologic abnormality. Recent outbreaks of bovine spongiform encephalopathy and pathogenic avian influenza have increased fish consumption in Korea. Methyl-mercury, a type of organic mercury, is present in higher than normal ranges in the general Korean population. When we examine a patient with chronic fatigue, we assess his/her methyl-mercury concentrations in the body if environmental exposure such as excessive fish consumption is suspected. In the current case, we learned the patient had consumed many slices of raw tuna and was initially diagnosed with chronic fatigue syndrome. Therefore, we suspected that he was exposured to methyl-mercury and that the mercury concentration in his hair would be below the poisoning level identified by World Health Organization but above the normal range according to hair toxic mineral assay. Our patient’s toxic chronic fatigue symptoms improved after he was given mercury removal therapy, indicating that he was correctly diagnosed with chronic exposure to organic mercury.
