Immunoxel (Dzherelo) is an oral, herbal immunomodulator used in Ukraine for adjunct therapy of infectious and autoimmune diseases. Antiretroviral drug-naive, tuberculosis (TB)/HIV coinfected patients with active pulmonary TB were divided into two arms, A (n = 20) and B (n = 20), to receive first-line anti-TB therapy (ATT) or ATT + Dzherelo, respectively. As a result, three (16%) versus 12 (67%; p = 0.003) patients had Mycobacterium tuberculosis culture conversion, with time to negative culture of 6 and 4 months in arms A and B, respectively. In the ATT-alone arm, the healing of pulmonary cavitations was observed in 25% of patients at weeks 24-28, while 60% of individuals in arm B healed at 16-18 weeks (p = 0.025). The TB lesions, on chest x-ray, had cleared in 46 and 84%, with time-to-clearance of 24-28 and 16-18 weeks in arms A and B, respectively. In the ATT-alone arm, the bodyweight at baseline was 64 +/- 6.3 kg, with 13 cachexic patients who had an average weight deficit of -5.2 +/- 1.7 kg. At the end of 6 months of follow-up, they have lost an additional 0.6 kg (-5.8 +/- 2.4). The study entry-level weight in arm B was 52 +/- 5.7 kg, with 12 individuals who had a body mass deficit of -8.5 +/- 2.7 kg. The immunotherapeutic intervention increased bodyweight by an average of 5.8 +/- 2.6 kg above baseline (p < 0.0001). The inclusion of Dzherelo into the ATT regimen decreased the incidence of new opportunistic infections (OI) with three episodes of OI versus 12 in arm A (p = 0.003). These findings indicate that Dzherelo contributes positively to the clinical efficacy of TB drugs.

ABSTRACT: V-5 Immunitor (V5) has been evaluated in patients with chronic hepatitis C with concomitant HIV and Mycobacterium tuberculosis infections. Once-daily tablet of V5 was administered per os to 20 patients for one month. Every patient who entered the study had enlarged liver, elevated hepatic damage markers, which at the end of study have improved in 19 out 20 (95%) patients. The reduction was highly signifi cant, from 1.72±0.34 to 0.18±0.28 μmol/ml•h (P=5.0 E-012) and 22.1±3.4 to 10.9±2.5 μM/L (P=5.7 E-009) for ALT and total bilirubin respectively. Enlarged liver reduced from 3.5±1.4 to 0.95±1.1 cm above normal size (P=2.9 E-009). As patients were hospitalized in TB hospital they were treated with standard anti-TB therapy (ATT) in addition to V5. Surprisingly, V5 appeared to contribute to higher and faster than expected sputum conversion rate; 94.4% of smear-positive patients became negative within one month. TB-associated fever subsided within mean/median 4.1/3 days; indicators of infl ammation such as elevated erythrocyte sedimentation rate and high leukocyte counts returned back to normal from 32.3±11.4 to 9.9±6.4mm/h (P=3.7 E-008) and 14.3±3.9 to 4.7±1.4x109L (P=7.1 E-010) respectively. Average body weight gain was 7.7 kg (P=4.6 E-007) and hemoglobin levels increased from 114±7.1 to 123.4±6.6 g/L (P=1.4 E-007). No adverse events were observed at any time. After one month 17 out of 20 patients were deemed cured from TB and discharged from the dispensary. Further studies are needed to confi rm this preliminary observation suggesting that in addition to the benefi cial effect in managing chronic hepatitis, V5 might also be useful as a safe and effective means for immunotherapy of tuberculosiJournal of Vaccines and Vaccination 10/2010; 01(01).

ABSTRACT: This Phase IIb, placebo-controlled study involved 55 TB patients treated with anti-TB therapy. They were divided into two groups, matched by age, gender, baseline bodyweight and clinical manifestations: one group (n = 27) received a once-daily V-5 Immunitor (V5) immunotherapy pill and the other (n = 28) received placebo. Only one (3.7%) and three (10.7%) subjects in V5 and placebo arms, respectively had first-diagnosed, drug-sensitive TB; the remaining patients had re-treated TB, multidrug-resistant TB or HIV-TB coinfection. After 1 month, 26 out of 27 patients (96.3%) became sputum smear negative in the V5 group (p < 0.0000001), whereas seven out of 28 (25%) in the placebo group had converted (p = 0.005). V5 contributed to the downregulation of TB-associated inflammation, as shown by normalization of high leukocyte counts, erythrocyte sedimentation rate and faster defervescence than controls. Patients in both arms experienced an increase in the levels of hemoglobin corresponding to 128.9 ± 17.6 versus 133.1 ± 14.7 g/l (p = 0.03) and 112.6 ± 14 versus 117 ± 11.7 g/l (p = 0.03) in V5 and placebo arms, respectively. In total, 19 out of 28 placebo patients (67.9%) gained, on average, 1.07 kg (59.1 ± 10 vs 60.1 ± 10.4 kg; p = 0.003). By contrast, all patients in the V5 group gained weight with mean 3.4 kg (59.7 ± 8 vs 63.1 ± 9 kg; p = 5.7E-007). Clinical symptoms improved among all patients in V5 arm, while 28.6% of patients on placebo reported satisfactory results (p = 0.007). No adverse or side effects attributable to V5 were seen at any time. Further studies are needed to gauge the extent of the benefits of V5 as safe and effective adjunct immunotherapy for TB.Immunotherapy 02/2011; 3(2):181-91. DOI:10.2217/imt.10.96 · 2.07 Impact Factor

ABSTRACT: 5-O-methylglovanon (5-O-MG) is a bioactive compound that was first isolated and characterized from Glycosmis plants. In this study, we found that chemically synthesized 5-O-MG has antimicrobial ability against eleven clinical ampicillin resistant Staphylococcus aureus and S. epidermidis isolates. The MICs of 5-O-MG against the S. aureus and S. epidermidis isolates were 12.5-50 μg/mL and 25-50 μg/mL, respectively. In combination with ampicillin, a synergistic interaction between 5-O-MG and ampicillin against the eleven resistant Staphylococcus isolates was observed, with fractional inhibitory concentration indices of 0.03-0125. Moreover, the anti-staphylococcal activity of 5-O-MG in combination with ampicillin was comparable with that of clavulanic acid in combination with ampicillin. The drug combination had no antagonistic effects when tested against any of the strains. Time-killing assays confirmed the synergy between 5-O-MG and ampicillin (p < 0.01). The combination of these two agents yielded greater than a 2 log(10) cfu/mL decrease in comparison with 5-O-MG or ampicillin alone. These findings suggest that 5-O-MG is a promising compound with the potential for future anti-staphylococcal drug development.Archives of Pharmacal Research 10/2011; 34(10):1751-7.
