ABSTRACT
OBJECTIVE: This study was undertaken to assess the effectiveness of Eupatorium perfoliatum (EP) 30C on the incidence of dengue fever and acute febrile illness (AFI) during the 2017 dengue outbreak. METHODS: We conducted a prospective, open-label, community-based parallel cohort study involving apparently healthy individuals residing in 06 urban slums (JJ colony) of Delhi. The participants were enrolled in two cohorts - the medicine cohort (MC) and the control cohort (CC). Participants in MC were given weekly one dose of EP 30C for 10 weeks along with Information, Education and Communication (IEC) material regarding dengue. Participants in the CC were provided with the IEC material only. The primary outcome measure was the incidence of dengue fever as per case definitions notified in the national guidelines for clinical management of dengue fever by the Government of India during the 10 weeks follow-up period. The secondary outcome measures were the incidence of AFI and the hospitalization of confirmed dengue cases. RESULTS: The analysis included 40,769 participants residing in 06 slum clusters of Delhi out of which 28,321 participants were in MC and 12,448 participants were in CC. The incidence of laboratory-confirmed dengue in the MC was 2.57 per 10,000 person-weeks (95% confidence interval [CI], 2.02-3.22) in comparison with 7.55 per 10,000 person-weeks (95% CI, 6.12-9.21) in the CC. The incidence of AFI in the MC was 19.66 per 10,000 person-weeks (95% CI, 18.07-21.36) in comparison with 40.96 per 10,000 person-weeks (95% CI, 37.48-44.67) in the CC. The overall protective effect of EP against laboratory-confirmed dengue was 65.77% (95% CI, 53.37-74.87; p = 0.0001) and against AFI was 52.58% (95% CI, 46.37-58.07; p = 0.0001). Hospitalization reported in the MC was nil as against 4.35% in the CC. No dengue-related case fatalities were reported from either cohort. None of the participants from the MC reported any adverse events owing to the prophylactic intervention. CONCLUSION: The study concludes that EP 30C was able to prevent dengue significantly. Randomized controlled trials are needed to confirm or refute our findings.

OBJECTIVE: This work was undertaken to evaluate the protective effect of Arsenicum album 30C against COVID-19. DESIGN: The work was designed as a prospective parallel cluster cohort study. INTERVENTION: Participants were enrolled in a homeopathy intervention (HI) cohort (who received Arsenicum album) or in a non-intervention (NI) cohort (who received no systematic intervention) from COVID-19 containment areas of Delhi. Individuals of age 5 years or above were given four medicated pills of Arsenicum album 30C, while those from 1 to 5 years old were given two medicated pills in each dose. RESULTS: The analysis included 10,180 individuals residing in 11 COVID-19 containment areas in Delhi, out of which 6,590 individuals were in the HI cohort and 3,590 individuals were in the NI cohort. The overall protective effect of Arsenicum album 30C was 83.43% (95% confidence interval [CI], 76.77 to 88.17): 45 cases per 6,590 (8.34 per 10,000 person-weeks) in the Arsenicum album 30C group versus 143 cases per 3,590 (45.01 per 10,000 person-weeks) in the NI cohort. The protective effect of Arsenicum album 30C against laboratory confirmed COVID-19 was 74.40% (95% CI, 55.08 to 85.41): 18 cases per 6,590 (3.32 per 10,000 person-weeks) in the Arsenicum album 30C group versus 38 cases per 3,590 (11.85 per 10,000 person-weeks) in the NI cohort. CONCLUSION: The use of Arsenicum album 30C was associated with some protection against probable and laboratory-confirmed COVID-19 in a containment-zone setting. Randomized controlled trials are needed to confirm or refute these results.
