A prospective study of the relationship between disease activity and psychologic distress in patients with inflammatory bowel disease

BACKGROUND

The evaluation of psychologic states is very useful in the management of inflammatory bowel disease (IBD) patients, particularly when related to disease activity (DA). Our aim was to prospectively evaluate the relationship between psychologic distress and DA.

METHODS

DA and psychologic distress were evaluated in 104 IBD outpatients by means of clinical criteria and the Hospital Anxiety and Depression Scale (HADS) at base line and after 6 months. Patients were grouped in unchanged, improved, and worsened DA from base line to follow-up.

RESULTS

Repeated-measures ANOVA showed a significant group-by-time interaction for HADS anxiety (F = 89.6, P = 0.0001) and depression (F = 3.67, P = 0.03) subscales.

CONCLUSIONS

Over time changes in DA significantly affect psychologic distress and are closely related to corresponding increases and decreases in anxiety and depression in IBD patients. Our findings therefore suggest that the assessment of psychologic distress, particularly anxiety, should be included in the clinical management of IBD patients.

Alexithymia and functional gastrointestinal disorders. A comparison with inflammatory bowel disease

BACKGROUND

Although the alexithymia construct was derived from observations of patients with classical psychosomatic diseases, empirical studies have found only a moderate association between alexithymia and inflammatory bowel disease (IBD). Indeed, there is some evidence that alexithymia may be associated more strongly with functional somatic symptoms than with the psychosomatic diseases. The present study examined the relationship between alexithymia and functional gastrointestinal disorders (FGIDs) in a group of 121 FGID patients, and compared the results with findings from a group of 116 IBD patients and a group of 112 healthy subjects.

METHOD

The subjects completed the 20-item Toronto Alexithymia Scale and the Hospital Anxiety and Depression Scale.

RESULTS

The FGID group was significantly more alexithymic than the IBD group, and the two gastrointestinal groups were more alexithymic than the normal healthy group. These differences remained even after controlling for the influence of education, gender, anxiety, depression and gastrointestinal symptoms.

CONCLUSIONS

The finding of a high rate of alexithymia (66%) in the group of FGID patients is consistent with the propensity of these patients to somatization and to high levels of poorly differentiated psychological distress.

A longitudinal study of alexithymia and psychological distress in inflammatory bowel disease

A group of 104 patients with inflammatory bowel disease (IBD) was followed longitudinally for 6 months. While anxiety and depression scores were influenced over time by changes in the level of disease activity, there was no significant change in alexithymia scores. The findings support the contention that alexithymia is a stable personality characteristic in some IBD patients, in contrast to anxiety and depression which are state phenomena influenced by the level of disease activity.

Assessing somatization in functional gastrointestinal disorders: integration of different criteria

BACKGROUND

Psychiatric assessment of somatization (the tendency to experience and communicate psychological distress in the form of physical symptoms and to seek medical help for them) currently rests on DSM criteria. An alternative diagnostic and conceptual framework has been proposed by an international group of psychosomatic investigators. The aim of this study was to compare these new criteria (Diagnostic Criteria for Psychosomatic Research, DCPR) with DSM-IV in a population where a high prevalence of psychosocial problems is expected (functional gastrointestinal disorders, FGID).

METHOD

One hundred and ninety consecutive patients with FGID in a tertiary care center were assessed according to DSM-IV and DCPR criteria.

RESULTS

The number of the 12 DCPR diagnoses was almost double that of DSM diagnoses. Only 9% of the patients were not identified by DCPR criteria, whereas this occurred in 25% of patients using DSM criteria. While patients who were given a DSM diagnosis frequently had additional DCPR diagnoses, many patients with DCPR syndromes did not fulfill any DSM criteria. Four DCPR syndromes appared to be particularly frequent and accounted for almost three quarters of the total diagnoses (alexithymia, persistent somatization, functional symptoms secondary to a psychiatric disorder, demoralization).

CONCLUSIONS

The joint use of DSM and DCPR criteria was found to improve the identification of psychological factors in FGID. The results may pave the way for changes in DSM classification of somatoform disorders.

Alexithymia in inflammatory bowel disease. A case-control study

The purported association between alexithymia and inflammatory bowel disease (IBD) was investigated in a group of 112 IBD patients (89 with ulcerative colitis and 23 with Crohn's disease) using the well-validated 20-Item Toronto Alexithymia Scale. Alexithymia was assessed also in a group of 112 normal subjects matched for gender, age, and education. The IBD group was significantly more alexithymic than the control group, and no significant difference was found between the ulcerative colitis and Crohn's disease patients. Alexithymia was unrelated to the duration of illness and the level of disease activity. Although the rate of alexithymia in the IBD group (35.7%) was significantly higher than the rate in the control group (4.5%), it is lower than rates of alexithymia that have been found among psychiatric patients with disorders that also have been linked theoretically and clinically with alexithymia.

Functional gastrointestinal disorders and eating disorders. Relevance of the association in clinical management

BACKGROUND

As functional gastrointestinal disorders (FGID) are common in eating disorder patients, we aimed to assess past eating disorders in patients referred for current FGID.

METHODS

One hundred and twenty-seven consecutive FGID outpatients and 163 patients with gallstone disease (GD) were enrolled. All patients were interviewed to detect GI symptoms (by means of the GI Symptom Rating Scale), lifetime eating disorders (on the basis of DSM-IV criteria), and current psychologic distress (on the Hospital Anxiety and Depression Scale).

RESULTS

Past eating disorders were significantly more prevalent in FGID (15.7%) than in GD patients (3.1%) (chi-square = 14.6, P < 0.001). FGID patients with past eating disorders were significantly younger, more educated, more psychologically distressed, more dyspeptic, and more were women than FGID patients without past eating disorders.

CONCLUSIONS

This study confirms the previously found association between functional GI symptoms and eating disorders and shows that functional GI symptoms may still persist even after the recovery from eating disorders, particularly in psychologically distressed patients.

Evaluation of a long-chain polyunsaturated fatty acid supplemented formula on growth, tolerance, and plasma lipids in preterm infants up to 48 weeks postconceptional age

BACKGROUND

The last trimester of pregnancy is a period of rapid accretion of long-chain polyunsaturated fatty acids, both in the central nervous system and the body as a whole. Human milk contains these fatty acids, whereas some preterm infant formulas do not. Infants fed formulas without these fatty acids have lower plasma and erythrocyte concentrations than infants fed human milk. Preclinical and clinical studies have demonstrated that single-cell sources (algal and fungal) of long-chain polyunsaturated fatty acids are bioavailable. A balanced addition of fatty acids from these oils to preterm formula results in blood fatty acid concentrations in low birth weight infants comparable to those of infants fed human milk.

METHODS

In the present study the growth, acceptance (overall incidence of discontinuation, reasons for discontinuation, overall incidence and type of individual adverse events), and plasma fatty acid concentrations were compared in three groups of infants fed a long-chain polyunsaturated fatty acid-supplemented preterm infant formula, an unsupplemented control formula, or human milk. The study was prospective, double-blind (formula groups only), and randomized (formula groups only). Two hundred eighty-eight infants were enrolled (supplemented formula group, n = 77; control formula group, n = 78; human milk group, n = 133).

RESULTS

Anthropometric measurements at enrollment, at first day of full oral feeding, and at both 40 and 48 weeks postconceptional age did not differ between the formula groups, whereas the human milk-fed group initially grew at a lower rate. The incidence of severe adverse events was rare and not significantly different between formula groups. The groups fed either human milk or supplemented formula had long-chain polyunsaturated fatty acid concentrations higher than those in the control formula group.

CONCLUSIONS

The results of this study demonstrate the safety and efficacy of a preterm formula supplemented with long-chain polyunsaturated fatty acids from single-cell oils.

Criterion-related validity of the diagnostic criteria for psychosomatic research for alexithymia in patients with functional gastrointestinal disorders

BACKGROUND

Because of criticism made against psychiatric assessment of somatization, alternative Diagnostic Criteria for Psychosomatic Research (DCPR) have been proposed by an international group of psychosomatic investigators. One of these criteria concerns the alexithymia construct. The main aim of the present study was to investigate the criterion-related validity of the DCPR for alexithymia syndrome (DCPR-A). A secondary aim was to explore the relationship between alexithymia and depressed mood.

METHOD

The study included 190 consecutive outpatients with functional gastrointestinal disorders. Alexithymia was assessed by means of the DCPR-A and the 20-item Toronto Alexithymia Scale (TAS-20). Depressed mood was assessed on the basis of the Depression subscale of the Hospital Anxiety and Depression Scale (HDS) and the DSM-IV criteria.

RESULTS

The sensitivity of the DCPR-A together with the TAS-20 was 70.2%, specificity was 81.6%, positive predictive power 88.9%, negative predictive power 66.0% and overall hit rate 46.8%. DCPR-A positives scored significantly higher than DCPR-A negatives on the TAS-20 scores (t = 9.86, p < 0.001). The TAS-20 was not associated with any measure of depression, while the DCPR-A was significantly associated with the HDS and DSM-IV criteria.

CONCLUSIONS

The DCPR-A had adequate sensitivity, specificity and accuracy, thus proving that the criterion has good validity. The differences in association found between alexithymia and depression suggest that they may be due to differences in the methods of investigation rather than to the constructs per se.

Type A behaviour: a reappraisal of its characteristics in cardiovascular disease

AIMS

  The role of type A behaviour in cardiovascular disease is controversial and most of the research is based on self-rating scales. The aim of this study was to assess the prevalence of type A behaviour in cardiology and in other medical settings using reliable interview methods that reflect its original description.

METHODS

A sample of 1398 consecutive medical patients (198 with heart transplantation, 153 with a myocardial infarction, 190 with functional gastrointestinal disorders, 104 with cancer, 545 with skin disorders and 208 referred for psychiatric consultation) was administered the Structured Clinical Interview for the DSM-IV and the Structured Interview for the Diagnostic Criteria for Psychosomatic Research (DCPR) which identifies 12 clusters, including type A behaviour.

RESULTS

A cardiac condition was present in 366 patients. There was a significant difference in the prevalence of type A behaviour in cardiovascular disease (36.1%) compared with other medical disorders (10.8%). Type A behaviour frequently occurred together with psychiatric and psychosomatic disturbances, particularly irritable mood, even though in the majority of cases it was not associated with DSM-IV diagnoses. Among cardiac patients, those with type A behaviour were less depressed, demoralised and worried about their illness.

CONCLUSIONS

Type A behaviour was found to occur in about a third of cases of patients with cardiovascular disease. Only in a limited number of cases was it associated with depression. It has a lifestyle connotation that may have important clinical consequences as to stress vulnerability and illness behaviour.

A cluster analysis-derived classification of psychological distress and illness behavior in the medically ill

BACKGROUND

The classification of psychological distress and illness behavior in the setting of medical disease is still controversial. Current psychiatric nosology does not seem to cover the spectrum of disturbances. The aim of this investigation was to assess whether the joint use of DSM-IV categories and the Diagnostic Criteria for Psychosomatic Research (DCPR), that provide identification of syndromes related to somatization, abnormal illness behavior, irritable mood, type A behavior, demoralization and alexithymia, could yield subtyping of psychosocial variables in the medically ill.

METHOD

A cross-sectional assessment using both DSM-IV and the DCPR was conducted in eight medical centers in the Italian Health System. Data were submitted to cluster analysis. Participants were consecutive medical out-patients and in-patients for whom a psychiatric consultation was requested. A total of 1700 subjects met eligibility criteria and 1560 agreed to participate.

RESULTS

Three clusters were identified: non-specific psychological distress, irritability and affective disturbances with somatization.

CONCLUSIONS

Two-step cluster analysis revealed clusters that were found to occur across clinical settings. The findings indicate the need of expanding clinical assessment in the medically ill to include the various manifestations of somatization, illness behavior and subclinical distress encompassed by the DCPR.

Effects of different psychophysiological stressors on the cutaneous electrogastrogram in healthy subjects

To evaluate the effect of psychophysiological stress on the gastric electrical activity, the cutaneous electrogastrography (EGG), a non-invasive technique, was performed in ten healthy subjects. Three different stressful (cold pressor test, arithmetic task, and Stroop color-word test) tests and a non-stressful (reading a booklet) task were administered, and EGG parameters (dominant frequency, coefficient of variation of dominant frequency, and gastric power) were recorded during baseline, task and rest periods. Neutral task did not affect EGG parameters. During stressful stimulations, a slight decrease in the dominant frequency and an increase in the coefficient of variation of the dominant frequency were found. During arithmetic task, the gastric power significantly increased (baseline vs stimulus P = 0.008; stimulus vs rest P = 0.015; baseline vs rest P = 0.011), and a statistically significant difference between gastric power during arithmetic and neutral task was observed (P = 0.007). During Stroop test, the gastric power showed only a trend toward significance (baseline vs stimulus P = 0.018; stimulus vs rest P = 0.018). A wide interindividual variability was recorded during the stress period. Therefore, the individual susceptibility to psychological stress may influence the EGG response and gastric electrical activity. In conclusion, cutaneous electrogastrography may be used as a non-invasive technique to study the effects of acute stressors on the gastric electrical activity.

Growth in human milk-Fed very low birth weight infants receiving a new human milk fortifier

BACKGROUND/AIMS

Human milk fortification has been advocated to enhance premature infants' growth. We, therefore, undertook this study of a new human milk fortifier containing more protein than a reference one.

METHODS

Open, randomized, controlled, multiclinic trial, with weekly growth parameters and safety evaluations in premature infants <1,500 g.

RESULTS

The 2 groups did not differ in demographic and baseline characteristics. The adjusted daily milk intake was significantly higher in the infants fed reference human milk fortifier (n = 29; 154.2 +/- 2.1 vs. 144.4 +/- 2.5 ml/kg/day, mean +/- SE; p < 0.05). Both human milk fortifiers produced increases over baseline in weight, length, and head circumference, with greater gains observed in the new human milk fortifier-fed infants for the former two parameters (weight gain 26.8 +/- 1.3 and 20.4 +/- 1.2 g/day, p < 0.05; head circumference 1.0 +/- 0.1 and 0.8 +/- 0.1 cm/week; length 0.9 +/- 0.1 and 0.8 +/- 0.1 cm/week, respectively). Serum chemistries were normal and acceptable for age. Study events were typical for premature infants and similar in both groups.

CONCLUSIONS

This new human milk fortifier had comparable safety to the reference human milk fortifier and promoted faster weight gain and head circumference growth.

A cross-cultural investigation of attachment style, catastrophizing, negative pain beliefs, and symptom severity in irritable bowel syndrome

BACKGROUND

Little information exists regarding whether psychosocial variables in irritable bowel syndrome (IBS) vary by geographic location. Adult attachment is an important psychological concept rooted in childhood relationship experience that has not been previously studied in IBS. Catastrophizing and negative pain beliefs have been described in IBS and may be affected by attachment.

AIMS

In this cross-cultural study, we determined: (i) whether attachment differs between IBS patients and controls, (ii) whether geographic location has a significant effect on attachment style, catastrophizing and negative pain beliefs, and (iii) how all three variables correlate with IBS symptom severity.

METHODS

463 IBS patients, with moderate to severe symptom scores, and 192 healthy controls completed validated questionnaires about attachment, catastrophizing, negative pain beliefs and IBS-SSS in nine locations, USA (New York, Los Angeles), Mexico, Italy (Rome, Bari), Romania, Iran, India, and China.

KEY RESULTS

Attachment anxiety and avoidance scores were significantly higher in IBS patients than in controls (p < 0.001). This was particularly true for the fearful-avoidant attachment category, especially in China and Romania. Path analysis showed that attachment anxiety and avoidance had indirect effects on IBS-SSS through catastrophizing (p < 0.0001) and negative pain beliefs (p = 0.005). All three psychosocial measures varied significantly depending on location.

CONCLUSIONS & INFERENCES

In the IBS population studied, attachment style was significantly different in IBS compared to a control population. Geographic differences in attachment, catastrophizing and negative pain beliefs were documented and their correlation with symptom severity and thus, research of psychosocial variables in IBS should take into account the location of the population studied.

Persistent dyspepsia after laparoscopic cholecystectomy. The influence of psychological factors

BACKGROUND

Many patients with gallstone disease continue to report gastrointestinal symptoms after cholecystectomy, but the predictive value of preoperative factors is not well understood. We aimed to investigate whether psychological symptoms can be associated with poor outcome after cholecystectomy in patients with gallstones and dyspepsia.

METHODS

A sample of 52 consecutive patients with uncomplicated gallstone disease and dyspepsia (conceived in a broader sense to include symptoms of the whole digestive tract) were assessed for psychological (revised 90-item Hopkins Symptom Checklist) and gastrointestinal symptoms (Gastrointestinal Symptom Rating Scale). One year after laparoscopic cholecystectomy, patients rated their gastrointestinal symptoms and were divided into improved and unimproved on the basis of the change in symptoms.

RESULTS

Twenty-one (40.4%) patients did not improve after surgery. Improved and unimproved patients did not differ in terms of sex, age, education or illness duration. Unimproved patients showed significantly higher psychological and dyspeptic symptoms than improved patients before surgery. Logistic regression showed that psychological factors were significantly associated with unimprovement after surgery.

CONCLUSIONS

Patients with gallstone disease and dyspeptic symptoms are unlikely to improve 1 year after surgery if they show psychological distress before surgery. Psychological symptoms were strongly associated with poor post-cholecystectomy outcome, thus highlighting the clinical relevance of joint assessment of psychological and gastrointestinal symptoms before surgery.

Transient aplastic crisis in hereditary spherocytosis

In this study the case of a child affected with hereditary spherocytosis, who presented with a presumably viral infection induced transient aplastic crisis, is described. The bone marrow aspirate showed phagocytosis of erythrocytes and nucleated cells by reticular cells. The possible pathogenetic role of bone marrow phagocytosis in aplastic crises in patients with haemolytic anaemias is discussed.

The predictive role of pelvic magnetic resonance in the follow up of spontaneous or induced puberty in turner syndrome

Puberty is a critical age for patients with Turner syndrome (TS): infertility is reported to be linked to karyotype and spontaneous puberty and menarche occur in approximately 30% of patients, especially in mosaicism. However, it is not always predictable considering hormonal pattern and pelvic transabdominal ultrasound scan (US).

The aim of the study is to compare the accuracy of Magnetic Resonance Imaging (MRI) and US to evaluate uterine and gonads volume, to visualize the presence of follicles and to predict spontaneous puberty and menarche in girls with TS. In a retrospective study, we evaluated 19 TS patients (age: 9–16 years), who underwent transabdominal pelvic US and pelvic MRI as required by parents. We correlated pelvic imaging with karyotype, hormonal data and pubertal outcome, and we compared US resolution to MRI.

MRI revealed a higher accuracy in the study of uterus and ovaries, and permitted to measure ovaries not visualized by US. Ovarian volume, the presence of follicles and the occurrence of spontaneous puberty were not related to the karyotype; spontaneous puberty started in one patient with a karyotype 45,X and in two patients with mosaicism (45,X/46,XX; 47,XXX/45, X). Ovarian follicles were relieved by MRI in patients with a spontaneous menarche and the persistence of menstrual cycles correlated with an ovarian volume corresponding to Tanner stage 3–4. We stress the role of MRI in the follow-up of TS adolescents, guide in the choice of the timing of treatment.

[Body Image Index in the Rorschach test in ulcerative proctocolitis]

The use of the Rorschach test allows the body image to be examined using the Body-Image Index formulated by Fisher-Cleveland. This index is obtained by calculating the responses to Penetration and Barrier. The hypothesis is that the diseases which affect the inside of the body are more greatly correlated to a high P score and a low B score (high P-low B type personality). The paper examines the Body-Image Index in a sample of 41 patients suffering from ulcerous rectocolitis comprising 24 males and 17 females with a mean age of 32 years. The personality profile obtained is of the "high P-low B" type with a P/R% ratio which is clearly higher than the central mean value (28.7% vs 8%) and a B/R% ratio which is clearly lower than the central mean value (4.2% vs 18%). The personality of the patients in this group was marked by a tendency to anxiety and a tendency to express aggression within their bodies (anger-in) which was field-dependent, difficulty in tolerating stress, a tendency to react somatically to conflicts, a low degree of body image stability and a constant need for an external holding object.

Risk factors for postoperative complications in preterm infants with surgical necrotizing enterocolitis and associated outcomes

BACKGROUND

We aim to determine clinical risk factors for postoperative complications in preterm infants with surgical necrotizing enterocolitis (NEC) or spontaneous intestinal perforation (SIP).

METHODS

A retrospective cohort study of preterm infants with surgical NEC or SIP to compare clinical factors between those with and without postoperative complications.

RESULTS

78/109 (71.5%) infants had any complication following surgical NEC. Adhesions (20/35, 57.1%) and wound infection (6/35, 17.1%) were the most common single surgical complications. Patients with a single surgical complication (35/66, 53%) were significantly less likely to be exposed to antenatal steroids, more frequently had a jejunostomy, needed a central line longer, and had a longer length of stay than those without any surgical complication. Infants with > 1 surgical complication (43/71, 60.5%) included mainly females, and had AKI more frequently at NEC onset, lower weight z-scores and lower weight for length z- scores at 36 weeks PMA than those without any complications.On multinomial logistic regression, antenatal steroids exposure (OR 0.23 [CI 0.06, 0.84]; p = 0.027) was independently associated with lower risk and jejunostomy 4.81 (1.29, 17.9) was independently associated with higher risk of developing a single complication. AKI following disease onset (OR 5.33 (1.38, 20.6), P = 0.015) was independently associated with > 1 complication in surgical NEC/SIP infants.

CONCLUSION

Infants with postoperative complications following surgical NEC were more likely to be female, have additional morbidities, and demonstrate growth failure at 36 weeks PMA than those without surgical complications. There was no difference in mortality between those with and without surgical complications.

Correlation between pituitary gonadotropin response to GnRH and testicular histology in subjects suffering from dyspermia

No significant changes of LH in basal conditions and in response to GnRH stimulation were found in any of the subjects studied; the same applies to basal testosterone and testosterone after HCG stimulation. On the other hand, the pituitary response for FSH gonadotropin showed significant variations in the different groups of subjects examined. These variations were closely correlated to the stages at which spermatogenesis was arrested. The earlier the stage of spermatogenetic arrest, the more strongly enhanced the FSH response to GnRH stimulation. Further, the most significant change, and the one most liable to be suited for purposes of diagnosis, was the one observed when passing from the 1st to the 2nd degree arrest (spermatids-spermatocytes). This FSH pattern is a constant finding; so much so that in the view of some authors testicular biopsy can now be avoided in cases with strongly increased pituitary FSH reserve since in these conditions the seminal line has been shown not to go beyond the stage of the spermatocyte.

Psychological distress and levels of disease activity in inflammatory bowel disease

The aim of this study was to evaluate the association between anxiety and depression, and levels of disease activity (LDA) in IBD patients. One hundred and fifty IBD patients (91 males and 59 females) were assessed by means of the Hospital Anxiety and Depression scale, and divided into three LDA groups according to standard clinical criteria: LDA1 = absence, LDA2 = mild, LDA3 = moderate and severe. Using the analysis of variance and the Scheffé test, a significant difference was found in the anxiety score, but not in the depression score, between LDA1 and LDA3 (p < 0.005). The risk of developing anxiety and depression in relation to LDA was estimated by multiple logistic regression. A significant linear trend (p < 0.01) to develop anxiety was found in the highest LDA. Our study showed that anxiety was significantly associated with a higher disease activity and suggested that anxiety should be appropriately evaluated and treated with the exacerbated symptoms in IBD patients.

[Disabling outcomes and psychological disorders in the patient with an enterostomy]

The authors carried out a retrospective study of patients undergoing enterostomy during the past 9 years. From 1981 to present a total of 60 patients (39 males and 21 females) were operated and subsequently followed-up. The aim of the study was to examine the following factors: the diagnosis which led to operation, the type of stoma used, early and late complications, the behaviour of the alvus, psychological disorders and Karnofsky's Performance-Status Index. After having presented the findings, the surgical results obtained are discussed together with the patient's psychological reactions to stoma. All types of early surgical complications were absent in 66.6% of patients, whereas late complications were absent in 41.6%. Even in those cases where surgical techniques and prostheses permitted a satisfactory post-operative outcome, the sociopsychological and sexual problems relating to the wound and the perceived difference between the real and ideal Ego are highlighted.
