Somatoform disorders

prof. MUDr. Hana Papežová, CSc.

Department of Psychiatry, First Faculty of

Medicine, Charles University and General

University Hospital in Prague

Characteristics

 Somatic complains of major medical maladies without demonstrable peripheral organ disorder

 Psychological problems and conflicts are important in initiating, exacerbating and maintaining the disturbance.

 Physical and laboratory examinations do not explain the vigorous and sincere patients´complaints.

 The morbid preoccupation interferes with and anxiety are frequently present and may justify specific treatment

Diagnostic guidelines

Somatization disorder F45.0

A definite diagnosis requires the presence of all of the following:

At least 2 years of multiple and variable physical symptoms with no adequate physical explanation has been found,

Persistent refusal to accept the advice or reassurance of several doctors that there is no physical explanation for the symptoms,

Some degree of impairment of social and family functioning attributable to the nature of symptoms and resulting behavior.

DSM- IV versus ICD

Somatization disorders appeared first in DSM-III.

Current diagnostic criteria (DSM-IV) are simplified and symptoms from each of four symptoms group (pain, 2

GIT, 1 sexual symptoms, 1 pseudoneurological ) are required.

Usually diagnosed in the primary care

Difficult when the patient forgets (represses) or refuses

(supresses) medically relevant information and critical events.

In contrast with current DSM IV the conversion disorder is assigned in ICD 10 to the cluster of dissociative disorders.

Differential diagnosis

Medical conditions multiple sclerosis, brain tumour, hyperparathyroidism, hyperthyroidism, lupus erythematosus

Affective (depressive) and anxiety disorders

1 or 2 symptoms of acute onset and short duration

Hypochondriasis - patient´s focus is on fear of disease not focus on symptoms

Panic disorder - somatic symptoms during panic episode only

Differential diagnosis

Conversion disorder - only one or two

Pain disorder one or two unexplained pain complaints, not a lifetime history of multiple complaints

Delusional disorders - schizophrenia with somatic delusions or depressive disorder with hypochondriac delusions, bizzare, psychotic sy.

Undifferentiated somatization disorder - short duration (e.g. less than 2 years) and less striking symptoms

Course of the illness

Chronic relapsing condition, the cause remains unknown

Onset from in adolescence to the 3th decade of life.

Psychosocial and emotional distress coincides with the onset of new symptoms and health care-seeking behavior

Clinical practice showed that typical episodes last 6 to 9 months with a quiescent time of 9 to 12 months..

Therapy and Prognosis

The somatization disorders considerably affects social life and working ability of patient.

Focus on management than treatment.

Management strategies undertaken

by primary care

Therapy and Prognosis

The major importance for successful management

Trusting relationship between the patient and one

(if possible) primary care physician

Frequent changes of doctors are frustrating and countertherapeutic.

Regularly scheduled visits every 4 or 6 weeks.

Brief outpatient visits - performance of at least partial physical examination during each visit directed at the organ system of complaint.

Therapy and Prognosis

Understand symptoms as emotional message rather than a sing of new disease

Avoid more diagnostic tests , laboratory evaluations and operative procedures unless clearly indicated

Set a goal to get selected somatization patients referral-ready for mental health care.

Group therapy (time limited, behavior oriented and structured group: peer support, improvement of coping strategies, perception and expression of emotions and positive group experience

Case history

52yrs, w.f.referred to general internist for back pain and multiple other complaints

Disabled from her job of machine operator

History of 10 operations, in 5 hospitals and 7 different physicians in last 2 yrs.

Physical examination: Obese, wearing transcutaneous el. nerve stimulation, cooperative, shows the various scars with certain enthusiasm.

Case history

Mental status examination :

Cooperative and pleasant, somewhat seductive, no pressure in her speech, euthymic, affect little shallow,no problems with discussing of intimate details of her life.

The remainder of MSE within normal limits.

Disallowing all back-related symptoms (some degeneration of vertebral bodies L2-5 revealed by spinal radiographs) positive for 8 pain symptoms: 2 sexual, 4

GIT, 2 pseudoneurological onset at 26 yrs.

Diagnosis of somatization illness made in the presence of comorbid medical condition.

Somatization disorder undifferentiated F45.1

Includes unspecified psychophysiological or psychosomatic disorder in patients whose symptoms and associated disability do not fit the full criteria for other somatoform disorders.

The treatment and the outcome however do not considerably differ.

Hypochondriac disorder F45.2

Characterised by a persistent preoccupation and a fear of developing or having one or more serious and progressive physical disorders.

Patients persistently complain of physical problems or are persistently preoccupied with their physical appearance.

The fear is based on the misinterpretation of physical signs and sensations.

Physician physical examination does not reveal any physical disorder, but the fear and convictions persist despite the reassurance.

Diagnostic guidelines

A definite diagnosis requires presence of both of the following criteria:

Persistent belief in the presence of at least one serious physical illness despite repeated negative investigations and examinations or persistent preoccupation with presumed deformity or disfigurement.

Persistent refusal to accept the advice and reassurance of several different doctors that there is no physical illness or abnormity underlying the symptoms.

Includes: Body dysmorphic disorder, Hypochondriasis,

Dysmorphophobia (non delusional), Hypochondriacal neurosis,

Nosophobia

DSM - IV and ICD - 10

In DSM IV criteria for hypochondriacal disorder are essentially the same as those of

ICD-10

Since DSM-I

In DSM-IV addition of poor insight during the current episode

Differential diagnosis

Ruling out organic disease , usually completed by the primary care physician.

Somatization disorder - in somatization disorder concern about symptoms indifference about diseas

x

the preoccupation with 1 or 2 physical illness persistent, no sex differences, no special familial context

Differential diagnosis

Signs of malingering - actually experienced symptoms reported rather simulate them.

Somatic delusions in psychotic disorders , depressive disorder schizophrenia and delusional disorders-the more serious disorders.

Anxiety and panic disorders-somatic symptoms of anxiety sometimes interpreted as signs of serious physical illness but the conviction of presence of physical illness do not develop.

Therapy and prognosis

To date no evidence-based treatment has been described.

The comorbid psychiatric symptom may facilitate the referral to psychiatrist and improve frequently the hypochondriasis

Otherwise patients strongly refuse the mental health care professionals and remain in primary health care.

Similar management and group therapy strategy as in somatization disorder may be useful.

Course of the illness

The illness is usually long-standing, with episodes lasting moths or years .

Frequently recurrences occurs after psychosocial distress and induce impairment in psychosocial functioning and work abilities. that approximately 50 % of patients show improvement , in other cases a chronic fluctuating course remain.

Higher socio-economic status, presence of other treatable condition, anxiety and depression, an acute onset, absence of personality disorder or comorbid organic disease predict better outcome .

Somatoform autonomic disorder F45.3

The somatoform autonomic disorder has been similar chronic relapsing condition as the somatisation disorder.

Patients report worse health than do those with chronic medical condition and their report of specific symptoms

If they meet the severity criteria is sufficient and need not to be considered legitimate by the clinician.

Somatoform pain disorders F45.4

Persistent severe and distressing pain that cannot be explained fully by a physiological process of physical illness.

It occurs in association with emotional conflicts or psychosocial problems.

Chronic pain - a way of seeking human relationship , attention and support

Sometimes dissipate when an accompanying psychiatric disorder is treated.

Somatoform pain disorders (2)

It has been always difficult to specify to which extend the chronic pain is associated with a given lesion.

The expression of chronic pain may vary with different personalities and cultures.

It has been clinically accepted that the patient is not malingering and the complaints about the extend of the pain are to be believed.

Anorexia nervosa F50.0

a) Weight is maintained at least 15% below that expected

(either lost or never achieved) , or Quetelet´s body-mass index is 17,5 or less . Prepubertal patients fail to make the expected weigh gain during the period of growth.

b) The weight loss is self induced by diets, avoidance of

“fatting foods” and one or more following: self-induced vomiting, self induced purging, excessive exercise, use of appetite suppressant and/or diuretics.

c) There is body image distorsion in the form of a specific psychopathology with increasing emaciation the patient’s feeling to be too large persists and she imposes herself a low weight threshold.

Anorexia nervosa F50.0

Endocrine disorder of hypothalamic-pituitarygonadal axis, amenorhea in women men by lost of sexual interest and potency.

“masked” by hormonal replacement therapy

Elevated levels of growth hormone, cortisol, decrease thyroidal hormone and abnormalities in insulin secretion.

Prepubertal onset-delayed or stopped development on juvenile level (growth, breasts and the genitals).

Bulimia Nervosa F50.2

a) Persistent preoccupation with eating and an irresistible craving for food , the patients have the episodes of binge eating during which a large amounts of food are consumed in a short period of time.

b) The patient attempts to compensate the

“fattening” effect of consumed food by one or more following behaviour: self-induced vomiting, abuse of laxatives or diuretics, alternating periods of starvation, use of appetite suppressants, thyroid hormones or manipulation insulin( mainly in diabetic patients).

Bulimia Nervosa F50.2

c) The psychopathology consists of

1.morbid dread of fatness (the patient set herself or himself a sharply defined weight threshold below the premorbid weight that constitutes the optimum or healthy weight).

2.

frequent history of anorexia nervosa , the earlier episode may have been fully or mildly expressed (mild form with moderate loss of weight and/or a transient phase of amenorhea).

METABOLIC SIGNALS

The role of leptin in malnutrition

Circulating leptin levels are in most of the malnutrition states decreased in paralelle with drop of body fat

Hypoleptinemia is rather the consequence than the cause of anorexia nervosa and most of the malnutrition states

Hypoleptinemia triggers complex adaptive response to limited energy sources (

 body fat). This adaptation includes decreased energy expenditure, amenorrhea, immunodeficiency etc.
