A study to compare the efficacy, acceptability and side effect of combined contraceptive vaginal ring with the combined oral contraceptive pills in a tertiary health centre located in central India

Background: A study to compare the efficacy, acceptability and side effect of combined contraceptive vaginal ring with the combined oral contraceptive pills in a tertiary health centre (RKDF Medical College and Research Centre, Bhopal) located in central India.Methods: This prospective randomized comparative trial enrolled hundred women aged between 20 to 40 years seeking for contraception with no contraindication to hormonal contraception. After proper counseling and informed consent, women divided into two groups, study group (50) includes women using contraceptive vaginal ring and control group (50) include women using combined oral contraceptives. The contraceptive efficacy, acceptability, tolerability and adverse events were recorded at each follow-up visit at RKDF Medical College and Research Centre, Bhopal.Results: Vaginal ring and combined oral contraceptives were found to have comparable contraceptive efficacy. In study group no pregnancy reported during study period while one pregnancy reported in control group, which was statistically insignificant. Satisfaction, continuation and recommendation to others were more with vaginal ring which were not significant statistically. Cycle control is superior with vaginal ring. Incidence of adverse effects was same in both groups.Conclusions: Combined contraceptive vaginal ring is an effective and reliable contraception with excellent cycle control, well-tolerated and highly acceptable to most women.

Eritema nodoso asociado al uso de anillo vaginal anticonceptivo / Erythema nodosum associated with the use of contraceptive vaginal ring

El eritema nodoso (EN) es la forma de paniculitis más común. Este trastorno representa una reacción de hipersensibilidad frente a diferentes antígenos, así como múltiples enfermedades sistémicas y fármacos, aunque en la mayoría de casos se desconoce la causa. Nuevos fármacos se añaden a la lista de involucrados en la etiopatogenia del eritema nodoso conforme van pasando los años, siendo uno de ellos los anticonceptivos hormonales orales combinados. El objetivo de este trabajo es proponer una relación entre los estrógenos de cualquier método anticonceptivo como puede ser el anillo vaginal combinado y la aparición del eritema nodoso.

Erythema nodosum (EN) is the most common form of panniculitis. This disorder represents a hypersensitivity reaction in front of different antigens, as well as multiple systemic diseases and drugs, although in most cases the cause is unknown. New drugs are added to the list of those involved in the etiopathogenesis of erythema nodosum as the years go by, one of them being combined oral hormonal contraceptives. The objective of this study is to propose a relationship between estrogens from any contraceptive method such as the combined vaginal ring and the appearance of erythema nodosum.
