[The psychological characteristics of dyspepsia. A controlled study with gastroscopic follow-up]. / Caratteristiche psicologiche della dispepsia. Studio controllato con follow-up gastroscopico.

It's known that some psychologic factors could be implicated in dyspepsia. Therefore, the psychologic aspects of 38 dyspeptic patients (17 males, 21 females, aged 18-65 years), who underwent digestive endoscopy, were evaluated by means of Rorschach and MMPI test. Patients with previous peptic ulcer history, with chronic ethanol or NSAID intake, operated on digestive tract and patients with behavioural problems were excluded. The results of psychological tests enhanced two main groups: anxiety patterns (17 patients--49%) and normal patterns (21 patients--55%). Endoscopic and histological findings moreover showed: "anxious" group--12 patients with chronic gastritis (HP+ 50%), 5 patients with normal endoscopy; "normal" group--16 patients with chronic gastritis (HP+ 87.5%), 5 patients with normal endoscopy. This study suggests that in about 50% of dyspeptic patients anxious pattern is present. Moreover chronic gastritis is more frequently associated to Helicobacter pylori in non-anxious patients.

Cholelithiasis in cirrhosis: analysis of 500 cases.

The prevalence of cholelithiasis (gallstones or previous cholecystectomy) was evaluated in a series of 500 cirrhotic patients from Northern Italy (329 males and 171 females, mean age 58 +/- 11 (SD) yr and 61 +/- 10 yr, respectively). Cirrhosis was related to chronic alcohol abuse in 180 cases, non-A non-B (NANB) hepatitis in 160, hepatitis B virus (HBV) in 94 (including 38 with concomitant alcohol abuse), idiopathic hemochromatosis in 44, and miscellaneous causes in the remaining 22 (including 15 with primary biliary cirrhosis). One hundred and sixteen patients (23.2%) had gallstones, and 31 others (6.2%) had previously undergone cholecystectomy, with an overall prevalence of cholelithiasis of 29.4%. The frequency was similar in both sexes (91/329 males, 27.7% vs. 56/171 females, 32.7%; p = NS), showed a slight increase with age, and differed significantly according to etiology (p less than 0.05), with the highest prevalence in the miscellaneous group and the alcoholics (36.4% and 33.3%, respectively). No significant difference was found in the prevalence of cholelithiasis according to Child's A, B, or C class.

T4+ cell depletion as a major risk factor for AIDS-related complex and AIDS. Longitudinal study of 253 HIV-antibody positive heroin addicts from northern Italy.

We enrolled 253 HIV-antibody positive heroin addicts without HIV-related disease (n = 81) or with persistent generalized lymphadenopathy (n = 172) in a prospective study to evaluate clinical progression to AIDS related complex (ARC) or AIDS and to identify factors of possible prognostic relevance. Follow-up lasted between 6 and 40 months (median 12 months). According to the non-parametric Cox's model the only significant (P less than 0.001) prognostic variable was T4+ cell count considered in three classes: greater than 800/microliters (no depletion), 400-800/microliters (moderate depletion) and less than 400/microliters (absolute depletion). Subjects with T4+ cell count of less than 400/microliters had a risk of developing ARC or AIDS that was 6.46 and 1.98 higher than those with values of greater than 800/microliters or between 400 and 800/microliters respectively. The estimated probability of progression to ARC or AIDS was 0.029, 0.056 and 0.172 at one year in subjects with T4+ cell count of greater than 800/microliters 400-800/microliters and less than 400/microliters, respectively, and 0.296, 0.501, and 0.896 at two years.

Prevalence of HIV infection in 646 heroin addicts and outcome of HIV-related conditions in the 266 followed up.

In a series of 646 heroin addicts anti-HIV was detected in 428 (66.2%) and HBsAg in 53 (8.2%). Forty-eight (90.5%) of the latter had concomitant chronic HDV infection. Markers of past HBV infection were found in 481 (74.4%). The prevalence of anti-HIV was significantly higher in the 534 subjects with HBV markers than in the other 112 without markers (69.8% versus 49.1%, p less than 0.001). Of the 266 anti-HIV positive subjects followed for 3-48 months (median 12), nine progressed from no disease to persistent generalized lymphadenopathy (PGL), 52 from PGL to AIDS-related complex (ARC) or AIDS (30 and 22 cases respectively), and six from ARC to AIDS. Baseline T4 + cell count was significantly lower and reduction during follow-up significantly greater in heroin addicts with disease progression than in those without.

HBV, HDV and HIV infections in 242 drug addicts: two-year follow-up.

Of 242 north Italian heroin addicts, 24 (9.9%) were HBsAg positive. HBeAg was positive in two of them (8.3%), anti-HBe in 16 (66.6%) and anti-HDV in 21 (87.5%). Of the 218 HBsAg negative, 182 (83.5%) had anti-HBc, 72 (33.0%) anti-HBe and 97 (44.5%) anti-HBs. One-hundred-eighty-five drug addicts were anti-HIV positive (76.4%); 77 of these (41.6%) were asymptomatic, 93 (50.3%) had PGL and 15 (8.1%) ARC. T4+ cell count was significantly lower in subjects with ARC as was T4+/T8+ ratio in subjects with PGL and ARC. During a median follow-up of 9.5 months (range 4-25), we observed three new cases of hepatitis (two caused by NANBV and one by HBV with HDV coinfection) and one new HIV infection. Ten anti-HIV positive subjects developed PGL and one AIDS.

HIV and HBV infection in intravenous drug addicts from northeastern Italy.

Three hundred and two intravenous drug addicts (IVDA) from five towns in Northeastern Italy were studied. Of the males, 37/249 (14.8%) were homosexuals and of the females, 29/53 (54.7%) were prostitutes; 118 (39.0%) were alcoholics. AST levels were abnormal in 31.8%, ALT in 45.7%, GTP in 36.4%, and bilirubin in 14.6%. The prevalence of HBsAg (13.9%) and HBeAg (21.4% of HBsAg positive) was significantly higher than in 2,983 controls (4.2% and 6.3%, p less than .001 and p less than .02, respectively). Of the HBsAg positive subjects, 51.7% had anti-HDV antibodies. Among 260 HBsAg negative cases, 146 (56.2%) were anti-HBs and anti-HBc positive, 76 (29.2%) were anti-HBc positive and anti-HBs negative (25 anti-HBe positive and 51 anti-HBe negative), and 38 had no HBV markers. Anti-HIV ELISA positive subjects came to 70.5% (triplicate determination with absolute concordance) and Western blot analysis confirmed the results in 99.1% of ELISA positive and 100% of ELISA negative subjects. The prevalence of anti-HIV was significantly higher in anti-HBc positive than negative cases (p less than .02), even excluding HBsAg positive subjects. Cases negative for HIV and HBV had a significantly lower median duration of drug abuse than those with past or present infection (36 vs 60 months, p less than .001). HIV-related diseases were present in 56.3% of the cases (120/213; PGL in 94, ARC in 24, and AIDS in two).(ABSTRACT TRUNCATED AT 250 WORDS)
