The association between HIV clinical disease severity and psychiatric disorders as seen in Western Romania

HIV disease continues to be a serious health issue all over the world. By the end of 2016, 36.7 million people were living with HIV, 1.8 million people became newly infected and 1 million died of HIV-related causes/diseases. In order to develop effective treatment strategies, is important to assess the risk factors that affect negatively the HIV-positive patients. HIV-infected patients are at high risk of developing psychiatric disorders in every stage of the illness. Psychiatric disorders can negatively influence the treatment adherence, induce risk behavior and influence the quality of life. The purpose of this study is to determine if the severity of HIV disease is associated with increased frequency of psychiatric disorders. We evaluated 101 HIV-positive patients receiving antiretroviral therapy in Western Romania via Psychiatric Diagnostic Screening Questionnaire (PDSQ). We conducted a risk analysis in order to see if the patients have a higher risk of developing psychiatric disorders depending on HIV serostatus factor (HIV asymptomatic, symptomatic, AIDS converted). Our study shows that, the patients having AIDS and symptomatic HIV have a higher prevalence for the most common psychiatric disorders: major depressive disorder (OR?=?5.81;p?p?=?0.016), agoraphobia (OR?=?4.31; p?=?0.024), social phobia (OR?=?2.81; p?=?0.038), generalized anxiety disorder (OR?=?4.79; p?=?0.006), somatization (OR?=?8.72; p?p?=?0.0013). Symptomatic HIV and AIDS converted serostatus is also a risk factor for post-traumatic stress disorder, obsessive-compulsive disorder and psychosis. The main conclusion of this study is that the more severe HIV clinical disease was associated with increased frequency of psychiatric disorders. As a consequence, we conclude that psychiatric disorders and HIV/AIDS treatment should be addressed simultaneously, depending on the risk specific factors such as the HIV infection stage and, due to psychiatric repercussions of HIV is expected to become more relevant in the coming years.     

Adrenal incidentaloma: a new cause of the metabolic syndrome?

A number of patients with adrenal incidentaloma are exposed to a slight degree of cortisol excess resulting from functional autonomy of the adrenal mass (usually a cortical adenoma). At present, there are only scant data on the unwanted effects of this endocrine condition referred to as subclinical Cushing's syndrome. The aim of the present study was to look for some features of the metabolic syndrome in patients with incidental adrenal adenoma. Forty-one patients (9 men and 32 women) bearing adrenal incidentaloma with typical computed tomography features of cortical adenoma were studied. For both patients and controls, exclusion criteria were age equal to 70 yr or greater, previous history of fasting hyperglycemia, or impaired glucose tolerance (IGT), severe hypertension, current use of medication or concomitant relevant illnesses, and body mass index (BMI) equal to 30 kg/m(2) or greater. Forty-one patients with euthyroid multinodular goiter accurately matched for sex, age, and BMI served for a 1:1 case-control analysis. The study design included an oral glucose tolerance test (75 g) and an endocrine workup aimed at the study of the hypothalamic-pituitary-adrenal axis. Age and BMI were fully comparable between patients (54.0 +/- 10.7 yr, 23.8 +/- 2.4 kg/m(2)) and controls (52.2 +/- 11.6 yr, 23.5 +/- 2.8 kg/m(2)). Fasting glucose and fasting insulin levels were not different between the two groups (4.96 +/- 0.61 mmol/liter vs. 4.88 +/- 0.58 mmol/liter; 67 +/- 34 pmol/liter vs. 59 +/- 32 pmol/liter), but the 2-h postchallenge glucose was significantly higher in patients than in controls (7.43 +/- 2.49 mmol/liter vs. 6.10 plus minus 1.44 mmol/liter, P = 0.01). Fifteen patients (36%) reached the World Health Organization criteria for IGT and two other patients (5%) reached those for diabetes, and 14% of the controls qualified for IGT (P = 0.01). No difference in the lipid pattern was seen between the two groups, but either systolic or diastolic blood pressure were higher in patients (135.4 +/- 15.5 mm Hg vs. 125.0 +/- 15.6 mm Hg, P = 0.003; 82.9 +/- 9.1 mm Hg vs. 75.3 +/- 6.6 mm Hg, P < 0.0001). We calculated the whole-body insulin sensitivity index derived from the oral glucose tolerance test that was significantly reduced in the patients (4.3 +/- 1.7 vs. 5.7 +/- 2.5, P = 0.01). In a multiple regression analysis, 2-h glucose was associated with BMI and midnight cortisol values (r(2) = 0.36, P = 0.002). The comparison of the patients with nonfunctioning adenoma (n = 29) with those with subclinical Cushing's syndrome (n = 12) yielded significant differences as to 2-h glucose and triglyceride levels, which were significantly higher in the second group (7.02 +/- 1.76 mmol/liter vs. 8.72 +/- 3.17 mmol/liter, P = 0.03; 1.06 +/- 0.4 mmol/liter vs. 1.73 +/- 0.96 mmol/liter, P = 0.002), but the insulin sensitivity index was conversely reduced (5.2 +/- 1.4 vs. 2.9 +/- 1.2, P < 0.0001). In conclusion, many patients with incidental adrenal adenoma display altered glucose tolerance, that may be explained by reduced insulin sensitivity, and increased blood pressure levels in comparison with carefully age- and BMI-matched controls. The slight hypercortisolism observed in some such patients may significantly contribute to this state of insulin resistance. Midnight serum cortisol appears as a sensitive marker of the metabolic effects of subclinical Cushing's syndrome.     

Muscle mass and functional recovery in men with hip fracture

OBJECTIVE: To investigate the association between muscle mass and functional recovery in men after hip fracture. DESIGN: We investigated 27 of 33 men admitted consecutively to a rehabilitation hospital after hip fracture. For each patient, we also studied two control women, matched for age and fracture type. Lean mass (LM) was assessed by dual-energy x-ray absorptiometry (DXA) 21.9 +/- 7.5 (mean +/- SD) days after fracture occurrence in the 27 men (22.8 +/- 7.2 days in the 54 control women). Appendicular LM (aLM) was calculated as the sum of LM in arms and legs. Functional recovery was assessed using Barthel index scores. Barthel index efficiency was calculated as the change in the Barthel index score after rehabilitation divided by the length of stay in hospital. RESULTS: After adjustment for age, height, fat mass, Barthel index scores at admission, and time between fracture occurrence and DXA assessment, aLM was significantly associated with Barthel index scores after rehabilitation (r = 0.480; P = 0.013) and Barthel index efficiency (r = 0.633; P = 0.001) in the 27 men. Conversely, in the 54 control women, no significant associations were found between aLM and the functional scores. CONCLUSIONS: LM assessed after hip fracture is significantly associated with the functional outcome in men.     

CYP11B2 -344T/C gene polymorphism and blood pressure in patients with acromegaly

CONTEXT: The pathogenesis of increased blood pressure (BP) in acromegaly is unclear, and the role of IGF-I levels and the renin-angiotensin-aldosterone system (RAAS) in this disease remains controversial. OBJECTIVE AND DESIGN: The aim of this study was to investigate the role of gene polymorphisms of the RAAS and involved in sodium handling on BP in acromegaly. SETTING AND PATIENTS: We conducted a multicentric retrospective study that included 100 consecutive patients with acromegaly referred during the period 2000-2003. INTERVENTION: All patients were genotyped for ACE I/D, AGT M235T, CYP11B2 -344T/C, B2R -58T/C, and alpha-adducin G460W polymorphisms. MAIN OUTCOME MEASURE: We assessed the prevalence of hypertension and BP according to the genotype. RESULTS: Patients with the CYP11B2 -344CC genotype displayed a significant increase in the risk of hypertension compared with patients with CT/TT genotypes (odds ratio = 4.0; 95% confidence interval = 1.4-11.6; P = 0.01). Consistently, a significant proportion of patients with the CYP11B2 -344CC genotypes were under antihypertensive treatment (73.1%) compared with patients with the TT/TC genotypes (38.2%; P = 0.003). Patients with the -344CC genotype displayed a significant increase in systolic BP (10.2 +/- 4.3 mm Hg; P = 0.02) but not a significant increase in diastolic BP (2.6 +/- 2.6 mm Hg; P = 0.32) compared with patients with the CT/TT genotype. CONCLUSIONS: We have shown an association of the -344T/C CYP11B2 gene polymorphism with BP in patients affected by acromegaly. These findings suggest that the RAAS is implicated in the pathogenesis of hypertension in acromegaly.     

Multiple myeloma: reduced plasma cell contamination in peripheral blood progenitor cell collections performed after repeated high-dose chemotherapy courses

The possibility of reducing tumour cell contamination by cytotoxic drug courses prior to peripheral blood progenitor cell (PBPC) collection was evaluated in two consecutives groups of multiple myeloma (MM) patient candidates for autograft. All patients were at disease onset and received two VAD (vincristine, doxorubicin and dexamethasone) courses as initial debulking. In the first group (44 patients), mobilization and harvest were performed ‘upfront’, after a single cyclophosphamide (CY) administration of 4 g/m²; in the second group (17 patients), PBPC were collected at the end of a high-dose sequential chemotherapy programme, including: CY 5 g/m², etoposide (VP16) 2 g/m², a chemotherapy-free interval with three courses of high-dose dexamethasone, a final mobilizing CY at 7 g/m². G-CSF was given following each high-dose cytotoxic drug. Cytofluorimetric analysis was performed to quantify progenitors (CD34⁺ cells) and plasma cells, identified by the high CD38 expression and/or CD38 and CD138 coexpression. Large amounts of PBPC were collected in either group (median harvested CD34⁺/kg: 15.8 × 10⁶ and 13.4 × 10⁶, respectively; P = 0.9). Circulating plasma cells were significantly higher in patients mobilized ‘upfront’ compared to those who received the high-dose sequence (median peak values of CD38^bright/μl: 39 and 10, respectively; P = 0.02); a similar difference was observed in the amount of con-taminating plasma cells in the harvest products (median CD38^bright/kg: 7.4 × 10⁶ and 1.3 × 10⁶, respectively; P = 0.02). The results demonstrate that an in vivo purging approach is feasible in myeloma patients through repeated high-dose chemotherapy courses; this may provide less-contaminated material suitable for further in vitro purging procedures.     

Molecular epidemiology of hepatitis C virus infection among intravenous drug users

Background/Aims: The clinico-pathologic features of hepatitis C virus infection intravenous drug users are different from those found in other hepatitis C virus-infected patients. Our airm was to test whether specific viral variants circulate within this particular patient population.Methods: We studied the distribution of hepatitis C virus genotypes in 90 drug addicts and 484 controls, according to the method described by Okamoto.Results: Hepatitis C virus type 1a and 3a infections were more frequent among intravenous drug users than in 125 age-matched controls (48.8% and 21.1% vs 17.6% and 11.2%), accounting for the majority of infections in intravenous drug users. Analysis of hepatitis C virus genotypes according to age showed that, in the general population, hepatitis C virus types 1a and 3a were more prevalent among patients younger than 40 years of age than in older individual (17.6% and 11.2% vs. 1.4% and 0.6%).Conclusions: These findings suggest that hepatitis C virus types 1a and 3a were recently introduced in Italy, presumably via needle-sharing among intravenous drug users, and from this reservoir they are extending to the general population, particularly among younger subjects.
