Hematobiochemical and Immunological Responses of Rats Treated with Multi-strain Probiotics and Infected with Trypanosoma brucei

The effects of treatment with probiotics on the immunological and hematobiochemical changes in Trypanosoma brucei infection were investigated. Probiotic strains used are Bifidobacterium BB-12, Lactobacillus acidophilus LA-5, Lactobacillus delbrueckii LBY-27, Lactobacillus paracasei LC-01, and Streptococcus thermophilus STY-31. Thirty rats randomly assigned to five groups were used in the experiment. Groups A to C received 1 × 10⁹ CFU, 5 × 10⁹ CFU, and 10 × 10⁹ CFU of the multi-strain probiotics daily and respectively from day 0 post-supplementation (PS) to termination. Group D and E were the infected and uninfected controls respectively. On day seven PS, groups A to D were challenged intraperitoneally with approximately 1 × 10⁶ trypanosomes. Parasitemia, nitric oxide level, hematobiochemical parameters, and antibody titer to heterologous antigen stimulation were monitored post-infection. By days 7 and 16 PS, probiotics-treated groups had significantly lower (p < 0.05) mean creatinine concentration than the controls; however, on day 7 PS, there were no significant variations in the leukocyte counts (LC), total erythrocyte counts (TEC), and the packed cell volume (PCV) in all experimental groups. Following infection, by day 16 PS, the pre-patent period, parasitemia levels, and antibody titer were similar in all infected groups. Furthermore, the probiotics-treated groups and the infected control had significantly lower PCV, TEC, and LC values when compared to the uninfected control, and probiotics treated groups (A and C) had only marginally lower nitric oxide levels than the infected control. Treatment with the probiotic strains gave a creatinine-lowering effect, was innocuous to the hematopoietic system, but was not sufficiently immunostimulatory in trypanosomosis.

Variations in utilization of health facilities for information and services on sexual and reproductive health among adolescents in South-East, Nigeria

Background

Adolescents' sexual and reproductive health has an important influence on a country's long-term national growth. There is a high level of burden due to poor adolescent sexual and reproductive health (ASRH) in Nigeria, especially the Ebonyi State. Evidence shows that in the Sub-Saharan African region, most adolescents experience poor access to information and other services relating to their sexual and reproductive health. Many cultures in Africa see matters around sex and sexuality as social taboos.

Aims

This study aimed to access variations in the utilization of health facilities for sexual and reproductive health information and services among adolescents in the Ebonyi State, Nigeria. This will inform the design of interventions to improve ASRH.

Patients and Methods

A total of 1,057 in-school and out-of-school adolescents aged 13-18 years were selected using cluster sampling of households from the six selected local government areas (LGAs) in this cross-sectional survey. Structured questionnaires were used to collect data. Descriptive statistics were performed alongside stratification analysis. Tabulation, bivariate and multivariate logistic regression analyses were undertaken. A household wealth index was calculated using the total household consumption calculated divided by the number of people in the household (per capita household consumption). The per capita household consumption was used to categorize the households into socioeconomic quintiles. The variable was used to differentiate key variables into socioeconomic quintile equity analysis.

Results

A majority of the respondents had never visited any type of health facility to receive either sexual and reproductive health (SRH) information (90.2%) or services (97.1%). The utilization rate of health facilities for SRH information was 9.8% while for other SRH services was 2.8%. The patent medicine vendor (PMV) was the most visited type of facility for SRH information and other services. Schooling was a strong predictor of health facilities' utilization for SRH information (P < 0.01) and other services (P < 0.01).

Conclusion

Utilization of health facilities for information and services among adolescents in the Ebonyi State is very low and favorable toward informal service providers such as PMVs. The establishment and strengthening of the existing youth-friendly centers, school clinics, and occasional outreach programs designed specifically to target adolescents would perhaps improve adolescents' access to adequate information and health facility utilization for sexual, reproductive, and health services.
