Although autonomic dysfunction has been described in primary amyloidosis patients, this has not been established for patients with secondary amyloidosis. This study examines the autonomic function of 23 biopsy-proven secondary amyloidosis patients (10 male, 13 female) and compares it with 19 healthy (8 male, 11 female) sex- and age-matched controls (Group III), using frequency- and time-domain HRV analysis. The study group was further divided according to renal function; Group I (14 nonuremic patients with serum creatinine level < 1.4 mg/dl) and Group II (9 uremic patients with serum creatinine level > 1.4 mg/dl). In time domain analysis, standard deviation and mean of the standard deviation of all normal R to R intervals, and standard deviation of the average normal R to R interval were significantly lower in Groups I and II as compared to Group III. In frequency domain analysis, low frequency power (LF), representing sympathetic function, was significantly lower in Groups I and II as compared to Group III, but high frequency power (HF), representing parasympathetic function, and the LF/HF ratio, as an index of sympathovagal balance, were not different among the groups. In conclusion, in patients with secondary amyloidosis, sympathetic components of heart rate variables decreased before the onset of uremia and the change became more prominent with the appearance of uremia despite not reaching statistical significance.","PeriodicalId":14590,"journal":{"name":"Israel journal of medical sciences","volume":"33 12","pages":"781-5"},"PeriodicalIF":0.0,"publicationDate":"1997-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20390593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main pathogens of early-onset sepsis were S. agalactiae (42%) and E. coli (32%). Seven of the 8 S. agalactiae cases were recorded during 1989-1990. The main pathogens of late-onset sepsis were Klebsiella spp. (31%), coagulase-negative staphylococci (18%) and Candida spp (16%). There were 11 cases (10%) of meningitis, 5 due to Klebsiella spp. The overall fatality rate due to sepsis was 14% (0.8/1000 live births) with an early-onset sepsis death rate of 37%.

The main trends recorded during the period of the study were 1) the emergence of S. agalactiae as the main pathogen of early-onset sepsis, followed by a sharp decrease in its incidence during the last part of the study, 2) the emergence of extremely virulent, multi-antibiotic-resistant Klebsiella organisms, and 3) the persistent high incidence of Candida sepsis.","PeriodicalId":14590,"journal":{"name":"Israel journal of medical sciences","volume":"33 11","pages":"734-8"},"PeriodicalIF":0.0,"publicationDate":"1997-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20363084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cancer patients receiving treatment for at least 6 months were asked to take the antidepressant, fluvoxamine, for 28 days. Before and at the end of the study, physical and psychiatric examinations were performed, and the severity of depression was assessed by the Hamilton Scale for Depression (HAM-D). In addition, a sample of blood was withdrawn from the patients to quantify the following parameters: total leukocyte and lymphocyte counts, T4, T8, and Natural Killer (NK) cells, and lymphocyte response to the mitogens phytohemagglutinin (PHA) and pokeweed (PWM). Ten adult patients completed the study. Five of the 10 responded favorably to fluvoxamine treatment. Mean improvement was 50% from the score on day one. There was a significant correlation between the change in the HAM-D score of the \"responders\" and the change in NK cell counts (p = 0.02). The mean increment in NK cell number was 53%. In 4 of the 5 \"non-responders\", NK cell number dropped by 65% (mean). No correlation between the change in HAM-D score and any other immunological parameters was detected. Fluvoxamine increases NK cell counts in cancer patients, probably by its antidepressant effect.","PeriodicalId":14590,"journal":{"name":"Israel journal of medical sciences","volume":"33 11","pages":"720-3"},"PeriodicalIF":0.0,"publicationDate":"1997-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20363081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to demonstrate the false-positivity of syphilis in patients with HCV infection, the false-positivity of anti-HCV in patients with syphilis and the validity of the serological tests in such patients. Fifty patients with positive anti-HCV, 21 patients with positive VDRL and 50 healthy subjects were studied. Syphilis serology was determined by the Venereal Disease Research Laboratory (VDRL) test and microhemagglutination for T. pallidum (MHA-TP) test. Hepatitis C serology was determined by a second generation ELISA (Ortho Diagnostics) test for HCV antibody, and anti-HCV positive patients were tested for HCV RNA by polymerase chain reaction (PCR). All assays were performed on all subjects. Not only the false-positive VDRL reaction in the patients with HCV infection but also false-positive anti-HCV tests in syphilitic patients have been observed. Four patients with syphilis had positive anti-HCV and negative HCV-RNA, whereas 10% (5 of 50) of patients with hepatitis C infection had positive VDRL and these patients were negative for MHA-TP test. The rates of false-positivity of VDRL and anti-HCV were higher than within the control group (p < 0.05). According to these data, positive anti-HCV in syphilitic patients and positive VDRL in chronic hepatitis C may be false-positive results with regard to the reaginic tests. Therefore, therapeutic measures should not be initiated without confirmation with a treponemal test or PCR. VDRL and HCV-ELISA tests may be interacted with IgM or IgG antibodies. This relationship should be investigated in further studies.","PeriodicalId":14590,"journal":{"name":"Israel journal of medical sciences","volume":"33 11","pages":"724-7"},"PeriodicalIF":0.0,"publicationDate":"1997-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20363082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
