RESUMO

El embarazo es un proceso fisiológico que conlleva modificaciones en órganos y sistemas, a su vez la adaptación a la altura involucra cambios fisiológicos, bioquímicos y genéticos. Esto ha ocasionado modificaciones en los valores hematológicos. Las mujeres gestantes residentes a nivel del mar reflejan una hemoglobina de 10 a 11 g/dl y una diferencia de 1,8 g/dl entre mujeres gestantes y no gestantes. Estos valores en mujeres gestantes residentes a 3.600 msnm precisan determinarse. Objetivo Determinar valores hematológicos de mujeres gestantes residentes a 3.600 msnm. Material y Métodos Muestras de sangre venosa periférica recolectadas en tubos vacutainer con EDTA de 190 mujeres no gestantes y 300 mujeres gestantes del Hospital de la Mujer de La Paz, Bolivia. Los estudios fueron realizados con contador automático Micros 60 (Horiba ABX diagnostics, Francia) y corroborados por técnicas manuales. Se empleó prueba "t-student" para comparar grupos y se consideró valor de p< 0.05 con IC de 95%. Resultados Las mujeres gestantes residentes a 3.600 msnm reflejaron hemoglobina de 13,6 ±2,3 g/dl,porcentaje de hematocrito 40,9±6,4% y reticulocitos 1,9± 0,7%. La diferencia de hemoglobina entre mujeres gestantes y no gestantes fue 2,6 g/dl. Conclusiones Los niveles de hematocrito y hemoglobina en mujeres gestantes habitantes a 3.600 msnm disminuyen y la disminución de concentración de hemoglobina es mayor en contraste con otras alturas. Los valores hematológicos de mujeres gestantes en la altura presentan diferencias significativas comparados con los del nivel del mar, probablemente por la adaptación fisiológica y genética a la altura.


Pregnancy is a physiological process that involves changes in organs and systems, and adaptation to high altitude also involves physiological, biochemical and genetic changes. This has caused changes in the hematological values. Pregnant women at sea level have a hemoglobin of 10 to 11 g/dl and a difference of 1,8g/dl between pregnant and non-pregnant women. These values in pregnant women living at 3600 masl need to be determined. Objective To determine hematological values of pregnant women living at 3600 masl. Material and methods It was collected peripheral venous blood samples in tubes vacutainer containing EDTA from 190 non-pregnant women and 300 pregnant women from Hospital de la Mujer in La Paz, Bolivia. Studies were carried out through Micro 60 automatic counter (Horiba ABX Diagnostic, France) and corroborated by manual techniques. T-student test was used to compare study groups and value of p <0.05 with 95% CI was used. Results Pregnant women residing at 3600 masl showed hemoglobin levels of 13,6 ± 2,3 g/dl, percentage of hematocrit 40,9 ±6,4% and reticulocytes 1,9 ± 0.7%. The difference of hemoglobin between pregnant and non-pregnant women was 2,6 g/dl. Conclusions Hematocrit and hemoglobin levels in pregnant women residing at 3600 masl are decreased. The decreased concentration of hemoglobin is higher compared to other altitudes. Pregnant women hematological values at high altitude are statistically different compared to sea level, probably due to physiological and genetic adaptation to high altitude.

RESUMO

BACKGROUND: Cervical cancer incidence and mortality rates in Bolivia are among the highest in Latin America. This investigation aims to evaluate the possibility of using simple devices, e.g. a cotton swab and a glass slide, for self-sampling in order to detect human papillomavirus (HPV) DNA by PCR in cervico-vaginal cells. METHODS: In the first phase of our study we evaluated the use of a glass slide as a transport medium for cervical cells. A physician took paired-cervical samples from 235 women. One sample was transported in Easyfix® solution and the other sample was smeared over a glass slide. Both were further analyzed and compared for human DNA recovery and HPV detection. A kappa value was determined to evaluate the agreement between the HPV DNA detection rates. In the second phase of the study, 222 women from the urban, peri-urban and rural regions of Cochabamba were requested to perform self-sampling using the following devices: a cotton swab combined with a glass slide, and a vaginal tampon. Women gave their opinion about the self-sampling technique. Finally, the agreement for high risk-HPV detection between self- and physician-collected samples was performed in 201 samples in order to evaluate the self-sampling technique. RESULTS: Firstly, the comparison between Easyfix® solution and the glass slide to transport clinical samples gave a good agreement for HPV DNA detection (κ = 0.71, 95% CI 0.60-0.81). Secondly, self-sampling, especially with cotton swab combined with glass slide, would generally be preferred over clinician sampling for a screening program based on HPV detection. Finally, we showed a good agreement between self- and physician collected samples for high risk-HPV detection (κ = 0.71, 95% CI 0.55-0.88). CONCLUSIONS: Simple devices such as a cotton swab and a glass slide can be used to perform self-sampling and HPV DNA detection. Furthermore, most Bolivian women preferred self-sampling over clinician-sampling for cervical cancer screening.
