Abstract

To evaluate the performance of the colorimetric resazurin microtiter assay (REMA) method for the detection of ofloxacin resistance.A panel of 120 multidrug-resistant Mycobacterium tuberculosis strains was tested blindly by the REMA method and compared with the results obtained using the BACTEC 460 method.A very good correlation was observed between the two methods.The REMA method is simple, rapid and can be an inexpensive alternative procedure for the rapid detection of anti-tuberculosis drug resistance in laboratories with limited resources.

Abstract

A seroepidemiological study was performed on HTLV-III, T. pallidum, C. trachomatis and Hepatitis B virus (HBV), in Butare, Rwanda, among 33 female prostitutes, 25 male customers of prostitutes, and 60 male and female controls. As compared with female controls the prostitutes had a higher prevalence of antibodies to HTLV-III (29/33 versus 4/33, p less than 0.001), T. pallidum (TPHA: 27/33 versus 6/33, p less than 0.001; RPR: 19/33 versus 2/33, p less than 0.001; FTA-Abs: 27/33 versus 5/33, p less than 0.001) and C. trachomatis (IgG IF: 31/33 versus 13/33, p less than 0.001). HBV serological markers were more often detected in the prostitutes than in the female controls (31/33 versus 18/33, p less than 0.001) although HBs antigen carriage rate was similar in both groups. As compared with male controls, the male customers of prostitutes had more frequently detectable antibodies to HTLV-III (7/25 versus 2/27, p = 0.05), and a positive RPR (10/25 versus 1/27, p less than 0.01). Among the 118 individuals studied, odds ratios and trend analysis disclosed a significant association between HTLV-III seropositivity and a positive TPHA, RPR, FTA-Abs, Chlamydia IgG IF test and serological markers to HBV. No association was found between HTLV-III seropositivity and HBs Ag carriage. This study suggests that HTLV-III has to be considered as an infectious agent transmitted among promiscuous Central African heterosexuals by sexual contact and/or parenteral contact with unsterile needles used for STD treatments.

Abstract

This study was undertaken within the framework of a surveillance project on the resistance of Mycobacterium tuberculosis to first-line antituberculosis drugs in four provinces of Rwanda with a high prevalence of tuberculosis (TB). The purpose was to determine the prevalence of primary and acquired resistance of M. tuberculosis to major antituberculosis drugs. A cohort of patients (n=710) with pulmonary TB documented by positive microscopic examinations of exhaustive samples was recruited at 7 treatment centers. Sputum samples were cultured on Löwenstein-Jensen and Coletsos media. Sensitivity to antituberculosis drugs was tested using a BACTEC 460 radiometric system. M. tuberculosis was isolated in 644 of the 710 patients (90.7%). A total of 296 out of 573 tested for HIV infection (51.7%) were positive. Primary resistance to one, two, three or four antituberculosis drugs was observed in 3.5%, 2.9%, 1.4% and 5.7% respectively. The prevalence of acquired resistance to antituberculosis drugs was 11.2%. Primary monoresistance to streptomycin was the most prevalent (2.3%) followed by resistance to ethambutol (1%). The combined rate of multiresistance was 11.6% with 7% involving new cases and 25.5% involving retreatment. This study showed that the rates of primary and acquired resistance to first-line antituberculosis drugs were high and that TB was associated with HIV infection. The National TB Control Program must implement measures to coordinate diagnosis and management of TB and HIV infection.

Abstract

During an 8-year study period, Arcobacter butzleri was the fourth most common Campylobacter-like organism isolated from 67,599 stool specimens. Our observations suggest that A. butzleri displays microbiologic and clinical features similar to those of Campylobacter jejuni; however, A. butzleri is more frequently associated with a persistent, watery diarrhea.

Abstract

There is an increasing demand to maximize energy savings of lighting sources. While High- Intensity-Discharge (HID) lamps are inherently very efficient, many users would like to further increase the energy savings of HID lamps through dimming. This paper presents a two-stage electronic ballast for HID lamps based on an adjustable rectifier followed a full bridge inverter. It is able to offer input utility current shaping with low frequency square wave sources without accompanying acoustic resonance. Dimming control method by varying DC link voltage and Duty-cycle control are utilized in the designed ballast. Theoretical analysis and experimental results of prototype ballast for 400W HID lamp are presented. They show the efficiency of the DC link voltage method compared to the other method for the energy saving while preserving all lighting requirement and gives a stable high-efficient lighting output.

Abstract

Introduction Treatment options for children with HIV-1 are limited. We aimed to compare activity and safety of three dualnucleoside analogue reverse-transcriptase inhibitor (NRTI) regimens with or without a protease inhibitor in previously untreated children with HIV-1. Methods In our multicentre trial, we randomly assigned 36 children to zidovudine and lamivudine, 45 to zidovudine and abacavir, and 47 to lamivudine and abacavir. Children who were symptomfree (n=55) were also randomly assigned to receive nelfinavir or placebo. Children with more advanced disease received open-label nelfinavir (73). Primary endpoints were change in plasma HIV-1 RNA at 24 and 48 weeks for the NRTI comparison and occurrence of serious adverse events for both randomised comparisons. Analyses were by intention to treat. Findings Children had a median CD4 percentage of 22% (IQR 15–29) and a mean HIV-1 RNA concentration of 5·0 log copies/mL (SD 0·8). One child was lost to follow-up and one died of sepsis. At 48 weeks, in the zidovudine/lamivudine, zidovudine/abacavir, and lamivudine/abacavir groups, mean HIV-1 RNA had decreased by 1·71, 2·19, and 2·63 log copies/mL, respectively (estimated in absence of nelfinavir) (p=0·02 after adjustment for baseline factors). One child had a hypersensitivity reaction to abacavir; and three with possible reactions stopped abacavir. There were 24 serious adverse events—six in the symptom-free children (all on nelfinavir), but none were attributed to nelfinavir. Interpretation Regimens containing abacavir were more effective than zidovudine/lamivudine. Such regimens could be combined with protease inhibitors and non-nucleoside reverse transcriptase inhibitors for safe and effective treatment of previously untreated children with HIV-1.
