Bilateral Radiological Involvement Paper
On x-ray finding (Table 5), bilateral radiological involvement, 16.7% of non-converted cases had unilateral lesions versus to 83.3% had bilateral ones with (P value 0.03) and could be consider a predictor of sputum non-conversion. Bouti et al.10 revealed that bilateral radiological involvement was independent risk factors for delayed smear conversion, due to the high baseline bacillary burden of those patients which delay time for conversion. Also, the study showed that 92.9% of the converted cases had localized lesions versus7.1% of converted were of diffuse lesions with (p value 0. Bilateral Radiological Involvement Paper

Regarding smoking status in relation to treatment response, after 2nd month of treatment, there were about 65.1% of converted cases non-smokers versus 34.9% smokers and at 6th month all non-converted cases were smokers (P value 0.04) (Table 6). Bilateral Radiological Involvement Paper
Regarding sputum positivity grading, 3 patients remained sputum positive at the end of treatment, those patients has a high sputum grading on their initial assessment; 2 patients had +3, and one patient had +4 sputum grading (P value 0.001) (Table 6). Bouti et al.10, Saffari et al.19 agree with current work. Singla et al.21 also found in their studies that the presence of large numbers of bacilli on pretreatment sputum smears was a main cause of delay conversion increasing the risk of persistent positivity because the greater the bacterial load the longer the time taken to eliminate the bacilli and eradicate the infection.
