Pulmonary tuberculosis diagnosis commonly relies on the bacteriological examination of sputum. A cross-sectional hospital-based study was carried out to compare on "on the spot" sputum staining using sodium hypochlorite (bleach method) and routine Ziel-Neelsen (ZN) staining technique. Study candidates included individual patients presenting with cough <3 weeks (Group I) and ≥3 weeks (Group II). Sensitivity and specificity of the bleach method was calculated and compared at 100% using the ZN staining technique as the standard. A total of 171 patients (94 males, 77 females) with mean age 34.9 years (SD ±12.9) were recruited. Fifty-eight patients had coughed for <3 weeks while 113 had coughed for ≥3 weeks. Smear-positive TB in Group I was 13.8% (95% CI = 5-23) while in Group II was 25.7% (95% CI = 21-29). Using the bleach method, the prevalence of smear-positive TB in Group II was 28.3% . This was an increase in smear-positivity rate of 15.6% as compared to the ZN technique. These results suggest that the use of bleach technique "on the spot" improve the sensitivity of tuberculosis diagnosis among patients with a history of coughing of over three weeks. However, further studies in different settings are recommended to validate the technique. _______________________________________________________________________________________
A hospital based open-label clinical trial of 19 apparently healthy adult males with microfilaraemia was conducted to assess safety, tolerability and efficacy of doxycycline on Wuchereria bancrofti. Study individuals were assigned 8 weeks treatment with doxycycline 200 mg daily. The results of different selected tests showed that, the haematological, hepatic, renal and clinical parameters pre-and post-drug administrations were within the normal range for all treated individuals. Clinical adverse events were mild, transient, tolerable and reported in 7/19 (36.8%) of the study cohort. The mf clearance rate was 100% at 12 months post treatment for the 13 individuals who completed the follow up. These findings indicate that, although the drug was administered for a long period, there was no evidence of toxicity to the myocardium, hepatocytes, renal, bone marrow and blood cells, suggesting that an 8-week course of 200 mg/day doxycycline is a safe and tolerable regime for the treatment of Wuchereria bancrofti infections.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
