Study Notes

Systemic Intolerance Disease: Referral and Management

Referral:
- Secondary organic causes of fatigue should be referred.
- Infections not responsive to standard treatment should be referred.
- Difficult to control hyper- or hypothyroidism should be referred
- Severe psychological illness should be referred
- Malignancy should be referred

Evaluation of Fatigue

Detailed Health History:
- Explore the onset, duration, and exacerbating factors of fatigue.
- Inquire about associated symptoms to uncover possible undiagnosed illnesses.
- Obtain a thorough medication history, including prescribed and over-the-counter medications.
- Obtain a detailed sleep history.
Screen for Psychiatric Disorders:
- Screen for underlying psychiatric disorders like depression, anxiety, and substance abuse.
Explore Psychosocial Issues:
- Explore psychosocial issues like home life and occupation.
Rule Out "Must Not Miss" Diagnoses:
- Rule out crucial diagnoses, such as anemia, hypothyroidism, and diabetes mellitus.

Interviewing the Patient: Questions to Ask

Open-Ended Questions:
- "Tell me about your fatigue."
- "How would you describe your mood?"
- "Have you experienced loss of self-esteem?"
- "Have you had more difficulty with sleep?"
- "What medications do you take on a regular basis (prescribed/OTC)?"
- "Have you recently started taking any new medications?"
CAGE Screening:
- "Do you use alcohol?"
Substance Abuse:
- "Do you use illicit drugs?"
- "Do you have more than one sexual partner?"
- "Have you recently traveled to developing countries?"

Constructing a Differential Diagnosis

Diagnosis of SEID (Systemic Exertion Intolerance Disease):
- Diagnosis relies on excluding chronic active organic illnesses that cause chronic fatigue.
- Lab results are "normal" for SEID.
SEID Diagnostic Timeline:
- Although SEID diagnosis requires at least 6 months of fatigue, clinical evaluation should rule out other treatable causes sooner.

Fatigue: Physical Exams

Vitals:
- Vital signs, including blood pressure, temperature, heart rate, and respiratory rate.
Oropharyngeal Exam:
- Examination of the throat.
Lymph Node Assessment:
- Assessment of the lymph nodes.

Fatigue: Lab Testing

Basic Lab Testing:
- Studies show limited positive predictive value of blood tests for fatigue as it's associated with a low probability of underlying organic pathology.
- Labs are often normal and may not be repeated unless clinically indicated.
Lab Tests:
- Complete blood count (CBC)
- Erythrocyte sedimentation rate (ESR)
- Chemistry Panel (glucose, electrolytes, blood urea nitrogen [BUN], creatinine, calcium)
- Thyroid function tests
- Pregnancy test (women of childbearing age)
- Urinalysis

Fatigue: Additional Testing

Consider Only if Clinically Indicated:
- Serum cortisol levels
- Antinuclear antibody, rheumatoid factor, immunoglobulin levels
- Lyme serology
- HIV antibody, Tuberculin skin test
- Toxicology screen
- Chest radiography
- Brain MRI
- Echocardiography
- Electrodiagnostic testing
- Polysomnogram

Electrodiagnostic Testing

Purposes:
- Assess nerve disorders (peripheral nerve disorders, myopathy, motor neuron disease, neuromuscular junction disorders)
- Investigate symptoms like muscle pain, numbness, cramps, spasms, abnormal twitching
- Evaluate nerve and muscle damage from injuries
Types: - Nerve Conduction Study - Electromyography

Fatigue: Definition and Epidemiology

Fatigue is a state of physical or mental exhaustion that makes it difficult to initiate or maintain activity.
It can negatively impact mental alertness, physical motor skills, judgment, and decision-making
It's a common symptom, usually short-lived, and often related to an identifiable cause
Fatigue can impact work, family, and social relationships
It's one of the most common symptoms encountered in primary care settings.
1 in 5 family medicine patients present with fatigue.
According to international surveys, fatigue is the main reason for 6.5% and a secondary reason for 19% of patient visits
1 in 3 adolescents report experiencing fatigue at least four days a week.
Men often describe fatigue as "tired," while women may describe it as "depressed" or "anxious."
The lifetime prevalence of significant fatigue, lasting at least two weeks, is approximately 25%.
Common causes include overexertion, deconditioning, viral illness, upper respiratory tract infection, anemia, lung disease, medications, cancer, depression, and surgery.
Fatigue lasting 6-12 weeks is not unusual after even minor surgery.

Fatigue Etiology and Classification

Fatigue of unknown cause (idiopathic fatigue) or related to psychiatric illness is more common than medically-related fatigue.
No etiology can be identified in approximately 1/3 of cases.
Up to 75% of patients with fatigue experience psychiatric symptoms.
Sleep disorders, especially obstructive sleep apnea and insomnia, are frequent among those with fatigue.
Fatigue in older adults increases the risk of negative health outcomes, such as mortality, disability in daily living, and physical decline.
Fatigue is classified by time frame:
- Acute fatigue: Lasts less than a month and resolves with rest.
- Subacute fatigue: Lasts between 1 and 6 months.
- Chronic fatigue: Lasts at least 6 months and doesn't improve with rest.
Fatigue is also classified by etiology:
- Secondary fatigue: Related to an underlying medical condition; may last more than a month but typically less than 6 months.
- Physiologic fatigue: Caused by an imbalance in sleep, exercise, diet, or other activities, not attributed to an underlying medical condition; improves with rest.

Fatigue: Diagnostic Criteria and Evaluation

Clinically relevant fatigue is characterized by three main components:
- Generalized weakness: Difficulty initiating activities.
- Easy fatigability: Difficulty completing activities.
- Mental fatigue: Difficulty concentrating and remembering.
Differentiating between sleepiness and fatigue:
- Sleepiness: Temporarily aroused by activity, at least in the short term; feels better after a nap.
- Fatigue: Intensified by activity; reports lack of energy, mental exhaustion, poor muscle endurance, delayed recovery after exertion, and non-restorative sleep.
Evaluating Sleep Quality and Quantity:
- Ask about bedtime, sleep onset time, time spent falling asleep, sleep interruptions, and sleep quality.
- Consider factors like medication use, alcohol consumption, and exercise habits.
- Use the Epworth Sleepiness Scale (ESS) to assess daytime sleepiness.
Interviewing the Patient:
- Explore the impact of fatigue on lifestyle, social and occupational function, and potential precipitating events.
- Distinguish fatigue from other symptoms like excessive sleepiness or breathlessness.
- Determine how fatigue has changed the patient's lifestyle.

Fatigue: Asking the Right Questions

Quality of Fatigue:
- Does fatigue affect work or home responsibilities?
- Has exercise been stopped due to fatigue?
- Does fatigue worsen with exertion?
- Does exercise lead to shortness of breath?
Time Course:
- When did fatigue begin?
- How long has fatigue lasted?
- Is fatigue worse in the morning, throughout the day, or at the end of the day?
- Did fatigue begin after surgery?
- Has the patient received radiation therapy?
Alarm Symptoms of Fatigue:
- Fever, night sweats, weight loss, excessive thirst/urination, abdominal pain, sore throat, lymph node enlargement, chest pain, shortness of breath, palpitations, joint pain/stiffness, back pain, sleep disturbance, etc.
Modifying Factors:
- Does fatigue only occur with exertion?
- Is fatigue unrelated to physical effort?
- Does fatigue improve on weekends?
- Does fatigue improve after a good night's rest?
Personal/Social Issues:
- Increased stress, family problems, work pressures, bereavement, lack of vacation time, etc.

Fatigue: Physical Exam

Vital signs: Blood pressure, temperature, heart rate, respiratory rate.
Oropharyngeal exam: Inspect the mouth and throat.
Lymph node assessment: Palpate lymph nodes for enlargement.
Additional physical exams are determined based on patient intake, suspected diagnoses, and must-not-miss diagnoses.

Fatigue: Lab Testing Recommendations

Basic laboratory testing is recommended but has a limited positive predictive value for underlying organic pathology, as fatigue is associated with a low pre-test probability of an underlying medical condition.
Lab results influence management in only 5% of patients. If initial results are normal, repeated testing is usually not indicated.
Basic testing includes CBC (complete blood count), ESR (erythrocyte sedimentation rate), Chemistry panel (glucose, electrolytes, BUN, creatinine, calcium), thyroid function, pregnancy test for women of childbearing age, and urinalysis.

Fatigue: Additional Testing & Electrodiagnostic Testing

Additional testing is only considered if clinically indicated.
It may include serum cortisol, antinuclear antibody, rheumatoid factor, immunoglobulin levels, Lyme serology, HIV antibody, tuberculin skin test, toxicology screen, chest radiography, brain MRI, echocardiography, electrodiagnostic testing, and polysomnogram.
Electrodiagnostic testing is used to assess for nerve disorders, including peripheral nerve disorder, myopathy, motor neuron disease, neuromuscular junction disorders, and muscle pain, numbness, cramps, spasms, abnormal twitching, and traumatic injury affecting nerves and muscles.
Types of electrodiagnostic testing include nerve conduction study and electromyography.

Fatigue: Summary and Key Points

Fatigue is a common, nonspecific symptom in primary care that can disrupt patients' lives.
It can be caused by a wide range of factors, highlighting the need for comprehensive history and physical examination.
Psychological and psychosocial factors are frequent causes, as are sleep disturbances and medication side effects.
Consider red flags for serious illnesses when taking patient history and reviewing their systems.
Laboratory and additional testing should be used to confirm specific hypotheses and assess for the most common causes.
Systemic Exertion Intolerance Disease (SEID) is a rare cause of persistent fatigue and should be considered only after ruling out other explanations.
A patient-centered approach, including empathy, affirmation, and regular follow-up, is crucial in managing fatigue.
Building a suitable circle of care is essential for effectively managing fatigue.
