Subthreshold autism spectrum disorder in patients with eating disorders.

AIM: Increasingly data suggest a possible overlap between psychopathological manifestations of eating disorders (EDs) and autism spectrum disorders (ASD). The aim of the present study was to assess the presence of subthreshold autism spectrum symptoms, by means of a recently validated instrument, in a sample of participants with EDs, particularly comparing participants with or without binge eating behaviours. METHODS: 138 participants meeting DSM-5 criteria for EDs and 160 healthy control participants (HCs), were recruited at 3 Italian University Departments of Psychiatry and assessed by the SCID-5, the Adult Autism Subthreshold Spectrum (AdAS Spectrum) and the Eating Disorders Inventory, version 2 (EDI-2). ED participants included: 46 with restrictive anorexia (AN-R); 24 with binge-purging type of Anorexia Nervosa (AN-BP); 34 with Bulimia Nervosa (BN) and 34 with Binge Eating Disorder (BED). The sample was split in two groups: participants with binge eating behaviours (BEB), in which were included participants with AN-BP, BN and BED, and participants with restrictive behaviours (AN-R). RESULTS: participants with EDs showed significantly higher AdAS Spectrum total scores than HCs. Moreover, EDs participants showed significantly higher scores on all AdAS Spectrum domains with the exception of Non verbal communication and Hyper-Hypo reactivity to sensory input for AN-BP participants, and Childhood/Adolescence domain for AN-BP and BED participants. Participants with AN-R scored significantly higher than participants with BEB on the AdAS Spectrum total score, and on the Inflexibility and adherence to routine and Restricted interest/rumination AdAS Spectrum domain scores. Significant correlations emerged between the Interpersonal distrust EDI-2 sub-scale and the Non verbal communication and the Restricted interest and rumination AdAS Spectrum domains; as well as between the Social insecurity EDI-2 sub-scale and the Inflexibility and adherence to routine and Restricted interest and rumination domains in participants with EDs. CONCLUSIONS: Our data corroborate the presence of higher subthreshold autism spectrum symptoms among ED participants with respect to HCs, with particularly higher levels among restrictive participants. Relevant correlations between subthreshold autism spectrum symptoms and EDI-2 Subscale also emerged.

Adult Autism Subthreshold Spectrum (AdAS Spectrum): Validation of a questionnaire investigating subthreshold autism spectrum.

AIM: Increasing literature has shown the usefulness of a dimensional approach to autism. The present study aimed to determine the psychometric properties of the Adult Autism Subthreshold Spectrum (AdAS Spectrum), a new questionnaire specifically tailored to assess subthreshold forms of autism spectrum disorder (ASD) in adulthood. METHODS: 102 adults endorsing at least one DSM-5 symptom criterion for ASD (ASDc), 143 adults diagnosed with a feeding and eating disorder (FED), and 160 subjects with no mental disorders (CTL), were recruited from 7 Italian University Departments of Psychiatry and administered the following: SCID-5, Autism-Spectrum Quotient (AQ), Ritvo Autism and Asperger Diagnostic Scale 14-item version (RAADS-14), and AdAS Spectrum. RESULTS: The AdAS Spectrum demonstrated excellent internal consistency for the total score (Kuder-Richardson's coefficient=.964) as well as for five out of seven domains (all coefficients>.80) and sound test-retest reliability (ICC=.976). The total and domain AdAS Spectrum scores showed a moderate to strong (>.50) positive correlation with one another and with the AQ and RAADS-14 total scores. ASDc subjects reported significantly higher AdAS Spectrum total scores than both FED (p<.001) and CTL (p<.001), and significantly higher scores on the Childhood/adolescence, Verbal communication, Empathy, Inflexibility and adherence to routine, and Restricted interests and rumination domains (all p<.001) than FED, while on all domains compared to CTL. CTL displayed significantly lower total and domain scores than FED (all p<.001). A significant effect of gender emerged for the Hyper- and hyporeactivity to sensory input domain, with women showing higher scores than men (p=.003). A Diagnosis* Gender interaction was also found for the Verbal communication (p=.019) and Empathy (p=.023) domains. When splitting the ASDc in subjects with one symptom criterion (ASD1) and those with a ASD, and the FED in subjects with no ASD symptom criteria (FED0) and those with one ASD symptom criterion (FED1), a gradient of severity in AdAS Spectrum scores from CTL subjects to ASD patients, across FED0, ASD1, FED1 was shown. CONCLUSIONS: The AdAS Spectrum showed excellent internal consistency and test-retest reliability and strong convergent validity with alternative dimensional measures of ASD. The questionnaire performed differently among the three diagnostic groups and enlightened some significant effects of gender in the expression of autistic traits.

Impact of Mood Spectrum Spirituality and Mysticism Symptoms on Suicidality in Earthquake Survivors with PTSD.

The aim of the present study was to explore the correlations between Spirituality/Mysticism/Psychoticism symptoms and suicidality in young adult survivors of the L'Aquila earthquake. The sample included 475 subjects recruited among high school seniors who had experienced the April 6, 2009, earthquake. Assessments included: Trauma and Loss Spectrum-Self Report and Mood Spectrum-Self Report (MOODS-SR). Mysticism/Spirituality dimension and suicidality were evaluated by means of some specific items of the MOOD-SR. The Spirituality/Mysticism/Psychoticism MOODS-SR factor score was significantly higher among subjects with PTSD diagnosis with respect to those without. Similarly, subjects with suicidal ideation, as well as those who committed a suicide attempt, reported significantly higher scores than those without.

Post-traumatic stress disorder in DSM-5: estimates of prevalence and criteria comparison versus DSM-IV-TR in a non-clinical sample of earthquake survivors.

BACKGROUND: The latest edition of DSM (DSM-5) introduced important revisions to PTSD symptomatological criteria, such as a four-factor model and the inclusion of new symptoms. To date, only a few studies have investigated the impact that the proposed DSM-5 criteria will have on prevalence rates of PTSD. METHODS: An overall sample of 512 adolescents who survived the L'Aquila 2009 earthquake and were previously investigated for the presence of full and partial PTSD, using DSM-IV-TR criteria, were reassessed according to DSM-5 criteria. All subjects completed the Trauma and Loss Spectrum-Self Report (TALS-SR). RESULTS: A DSM-5 PTSD diagnosis emerged in 39.8% of subjects, with a significant difference between the two sexes (p<0.001), and an overall 87.1% consistency with DSM-IV-TR. Most of the inconsistent diagnoses that fulfilled DSM-IV-TR criteria but not DSM-5 criteria can be attributed to the subjects not fulfilling the new criterion C (active avoidance). Each DSM-5 symptom was more highly correlated with its corresponding symptom cluster than with other symptom clusters, but two of the new symptoms showed moderate to weak item-cluster correlations. Among DSM-5 PTSD cases: 7 (3.4%) endorsed symptom D3; 151 (74%) D4; 28 (13.7%) both D3 and D4; 75 (36.8%) E2. LIMITATIONS: The use of a self-report instrument; no information on comorbidity; homogeneity of study sample; lack of assessment on functional impairment; the rates of DSM-IV-TR qualified PTSD in the sample was only 37.5%. CONCLUSIONS: This study provides an inside look at the empirical performance of the DSM-5 PTSD criteria in a population exposed to a natural disaster, which suggests the need for replication in larger epidemiological samples.

Hyperinsulinemic hypoglycemia associated with ectopic Cushing's syndrome due to a pancreatic endocrine tumor in a Type 2 diabetes mellitus patient: clinical implications of a rare association.

BACKGROUND: The coexistence of insulin and ACTH hypersecretion in the same patient is extremely rare. A diabetic patient with a pancreatic endocrine tumor (PET) co-secreting insulin and ACTH is even rarer and has never been described. The combination of these two endocrine syndromes results in a peculiar clinical picture. AIM: To determine the cause of glycemic variations in a patient with previously stable diabetes mellitus. SUBJECTS AND METHODS: This is a clinical case report from the Endocrinology Unit of Aosta Hospital and Internal Medicine and Surgical Unit of Verona University. A 69-yr-old diabetic patient was hospitalized for recurrent severe hypoglycemic events persistent after withdrawal of anti-diabetic drugs. The causes of hypoglycemia and subsequent resumption of hyperglycemia were investigated. RESULTS: An insulin-secreting PET was diagnosed. Diazoxide and octreotide therapy initially was able to control hypoglycemic symptoms, then, a Cushing's syndrome occurred resulting in worsening of diabetes control. ACTH was found to be released by the PET previously diagnosed as an insulin-secreting tumor. The tumor was removed and the histology was consistent with a well differentiated endocrine carcinoma. After surgery, adrenal function was normal and insulin therapy was again necessary to control diabetes. CONCLUSIONS: A single PET may be responsible for both a hyperinsulinemic and a Cushing's syndrome. When this rare association occurs, each of the two syndromes may affect the other resulting in a peculiar clinical course. Finally, an insulin-secreting PET has to be kept in mind as a rare cause of hypoglycemia in diabetic patients.

Lifetime post-traumatic stress symptoms are related to the health-related quality of life and severity of pain/fatigue in patients with fibromyalgia.

OBJECTIVES: The aim of the present study was to investigate the impact of lifetime potentially traumatic events, including losses, and of post-traumatic stress symptoms on the severity of illness and health-related quality of life in patients with fibromyalgia (FM). METHODS: Seventy patients with FM, diagnosed according to the American College of Rheumatology criteria, were consecutively enrolled at the Unit of Rheumatology of the University of Pisa, Italy. Assessments included: SCID-I/P; the Fibromyalgia Impact Questionnaire (FIQ) and the Medical Outcomes Study Short Form-36 Health Survey (MOS SF-36), for the severity of pain; the Health-Related Quality of Life (HRQoL); the Trauma and Loss Spectrum Self-Report (TALS-SR) life-time version. RESULTS: The FIQ total score was related to the number of loss events (Domain I) and to symptoms of grief reactions (Domain II) and re-experiencing (Domain V) of the TALS-SR. The 'VAS fatigue' scores (FIQ) were significantly related to the TALS-SR symptoms of grief reactions (Domain II) and re-experiencing (Domain V). The Mental Component Summary and Bodily Pain scores of the MOS SF-36 were significantly related to all TALS-SR domains, the latter with the exception of the VIII (Arousal). CONCLUSIONS: Our results corroborate the presence of a relationship between the lifetime exposure to potentially traumatic events, in particular loss events, and lifetime post-traumatic stress symptoms and the severity of illness and HRQoL in patients with FM.

Manic spectrum symptoms are correlated to the severity of pain and the health-related quality of life in patients with fibromyalgia.

OBJECTIVES: We aimed at investigating the impact of lifetime manic spectrum symptoms on the severity of pain and the health-related quality of life (HRQoL) in patients with fibromyalgia (FM). METHODS: One hundred and sixty-seven patients with FM, assessed according to the ACR criteria, were consecutively enrolled. Psychiatric diagnoses were carried out following the Diagnostic and Statistical Manual for Mental Disorders (DSM-IV-TR). The severity of pain and the HRQoL of FM patients was measured by means of the Fibromyalgia Impact Questionnaire (FIQ) and the Medical Outcomes Study Short Form-36 Health Survey (MOS SF-36); the mood spectrum symptomatology by means of the Mood Spectrum-Self Report (MOODS-SR). RESULTS: A high rate of lifetime manic symptoms was detected and resulted as related to the Pain Visual Analogic Scale ("pain VAS") of the FIQ and the FIQ total scores as well as to the "bodily pain", and to the physical and mental component summary scores of the MOS SF-36, both in the whole sample (n=167) and in FM patients without bipolar disorder (n=160). CONCLUSION: Our results highlight the need to pay more attention to manic spectrum symptoms and features in FM patients, because of their relationship with the severity of pain and with a worse HRQoL.

Ankle brachial pressure index usefulness as predictor factor for coronary heart disease in diabetic patients.

Ankle brachial pressure index (ABPI) is a non-invasive marker of atherosclerosis, helpful to identify subjects at high-risk for coronary heart disease (CHD) among large populations with cardiovascular disease (CVD) risk factors. The diagnostic role of ABPI has been also recognized in patients with diabetes. In the present study, the role of an ABPI score < 0.90 in predicting CHD has been evaluated in a large series of patients with Type 2 diabetes mellitus and compared to other known CVD risk factors. Nine hundred and sixty-nine (mean age was 66.1 yr) consecutive patients with Type 2 diabetes mellitus were evaluated. The patients were followed-up for 18.3+/-5.2 months (range 12- 24) and all events of CHD, defined as myocardial infarction, unstable and resting angina or coronary atherosclerosis at the instrumental investigation (at the coronary angiography and/or perfusion stress testing) were recorded. A rate of 17.5% of CHD events were recorded in diabetic population during the follow-up period. The relative risk of CHD was significantly increased for male patients [odds ratio (OR): 1.6; 95% confidence interval (CI): 1.1-2.2], patients with age > or = 66 yr (OR: 1.8; 95% CI: 1.3-2.5), body mass index (BMI) > 30 (OR: 1.5; 95% CI: 1.1-2.1), waist circumference > 88 cm for females and 102 cm for males (OR: 1.5; 95% CI: 1.0-2.1), proteinuria > or = 30 microg per min (OR: 1.6; 95% CI: 1.1-2.3), LDL-cholesterol > or = 100 mg/dl (OR: 2.1; 95% CI: 1.5-3.0), glycated hemoglobin > 7% (OR: 1.6; 95% CI: 1.1-2.3), insulin therapy (OR: 1.9; 95% CI: 1.3-2.9), and ABPI < 0.90 (OR: 3.7; 95% CI: 2.2- 6.2). BMI was higher in patients with ABPI < 0.90 than in those with ABPI > or = 0.90 (p<0.05). At the multivariate analysis, ABPI < 0.90 was the best factor independently associated with CHD (p<0.001). APBI < 0.90 is strongly associated to CHD in Type 2 diabetic patients. We recommend to use ABPI in diabetic patients and to carefully monitor diabetic subjects with an ABPI lower than 0.90.

Eradication of Helicobacter pylori infection with proton pump inhibitor-based triple therapy. A randomised study.

BACKGROUND: Helicobacter pylori (H. pylori) infection plays an important role in the pathogenesis of duodenal ulcer (DU) disease. Low DU recurrences and reinfection rates were universally described, when treatment was effective. It has been suggested that short-term triple therapy, comprising a proton pump inhibitor plus 2 antibiotics (clarithromycin, amoxycillin or a nitroimidazole), should be used as first choice in treating H. pylori infection. Nevertheless, conflicting results have been reported on using these treatment regimens in different countries. Our aim was to compare cure rates of H. pylori infection, with a 1-week triple therapy versus 10 and 15 day triple schedules, in patients with DU. METHODS: A total of 172 patients (91 males, mean age 56.2+/- 3.2 years) were randomly treated with a triple therapy including a standard dose of proton pump inhibitor, amoxicillin at a dose of 1 g twice daily and clarithromycin 500 mg twice a day. Sixty-six patients received a 1-week triple therapy (group I), 42 subjects were treated with a 10-day triple therapy (group II) and 64 others with a 14-day triple therapy (group III). H. pylori infection at entry and after eradication, at least 4 weeks after therapy had ended, were assessed by 13C urea breath test and histology on biopsies from the antrum and the corpus. RESULTS: At the end of the course of treatment, the overall H. pylori eradication rate was 68.2% (45/66) in group I, 76.2% (32/42) in group II and 71.9% (46/64) in group III, without any statistically significant difference between the 3 differing period regimens, although a trend for better results with the 10-day triple therapy was observed. Compliance was good and side effects infrequent and mild. CONCLUSIONS: None of the 3 periods of triple therapy achieved 80% eradication rate recommended by the Maastricht Consen-sus Conference. The 10-day triple therapy, although not significantly, provided a satisfactory treatment against H. pylori infection.
