Background: Peptic ulcer disease is a non-malignant, mucosal lesion of the stomach or duodenum. The mucosal defect reaches the muscularis mucosa and sometimes, beyond causing life threatening complications, including haemorrhage, perforations, gastrointestinal obstruction and malignancy.Methods: The animals were pre-treated with omeprazole 20 mg/kg and 300 mg/kg of Capparis cartillaginea decne orally for 14 days. On the 15th day, ulcers were induced using indomethacin 30 mg/kg and 4 hours post ulcer induction, they were sacrificed. Ulcer index, pH, total acidity and volume were determined.Results: Extensive lesions were seen in indomethacin ulcerated rats with mean ulcer score of (1.260±0.18). In comparison, there were minimal areas of erosion on animals pre-treated with omeprazole (0.14±0.025) and plant extracts (0.280±0.097). Indomethacin-induced ulcer treated animals showed the highest volume of gastric juice output (3.14±0.21 ml), whereas the animals pre-treated with omeprazole had lower gastric juice output (2.20±0.2 9ml). This was comparable to animals pre-treated with the plant extract (1.80±0.13 ml). The pH was high in animals pre-treated with omeprazole (5.02±0.53). This was also seen in animals pre-treated with the extract (4.82±0.31). This was in comparison to the low pH seen in indomethacin ulcerated animals (2.20±0.16). Indomethacin-induced ulcer treated animals showed high levels of total acidity (88.64±1.71 mEq/L). Whereas the animals pre-treated with omeprazole had lower total acidity (55.26±3.77 mEq/L), which was also mirrored in animals pre-treated with the plant extracts (61.44±2.42 mEq/L).Conclusions: The extracts of Capparis cartillaginea decne showed anti-ulcer effect on indomethacin induced ulcers in Wistar rats.
Résumé
Introduction: Early Infant Diagnosis (EID) is the practice of testing infants for HIV within the first 46 weeks of life or at the earliest opportunity possible so as to promptly link HIV-infected infants to healthcare and treatment. In the absence of timely HIV testing and Antiretroviral Therapy (ART) initiation, one-third of infants living with HIV die before their first birthday and more than half die before 2 years. Worldwide, Mother To Child Transmission (MTCT) rates accounted for 8.9% of all HIV infections by the end of 2015, with Sub-Saharan Africa accounting for 12% of these infections. In Kenya, MTCT infection rates were at 14%, accounting for 7% of all new infant infections globally by the same period. Objection: The objectives of this study was to establish the determinants of HIV positive status at first PCR Test among infants seeking EID services in some selected hospitals in the Nairobi County, Kenya. Materials and Methodology: A longitudinal cohort study employing a mixed-method approach was used. Quantitative data was collected from pairs of 163 mother-infant using interviewer administered, pre-tested, and semi-structured questionnaires. While qualitative data was collected using Focus Group Discussion (FGDs) guides, it was coded, cleaned and analyzed using STATA Version 14. Quantitative data was analyzed using Fisher's exact test (p= 0.1) and Poisson Regression (p= 0.05) at bivariate and multivariable levels respectively. Thematic analysis was undertaken for qualitative data. Results: The findings from the adjusted parsimonious model revealed that, three variables influenced the infant HIV status at first PCR test. The study participants who had been administered with ART during pregnancy had a lower risk (RR= 0.06) of getting HIV positive infants relative to those who hadn't received ARVs during pregnancy (95% CI 0.014, 0.213 p= 0.000). Respondents who had been initiated on ART during the first trimester had lower risk (RR= 0.1) of getting an HIV positive infant than respondents who were administered with ARVs in the third trimester (95% CI 0.014, 0.021, p= 0.001). Respondents on first-line regimen had a lower risk (RR= 0.04) of getting HIV infected infants compared to those who were on the second line regimen (95% CI 0.012, 0.114, p= 0.000) confirming all the three significant variables as protective factors. Conclusion: The study corroborate that, first line ART regimen administered before pregnancy or during the first trimester of pregnancy was effective in lowering the risk of getting an HIV positive infant. Pediatric HIV infection, disease progression is quite rapid and without prompt treatment, most infants might not survive their second birthday

Introduction: Asymptomatic bacteriuria (ASB) is the presence of bacteria in urine without apparent symptoms of urinary tract infections. The importance of asymptomatic bacteriuria lies in the insight it provides into symptomatic infections. To determine prevalence, bacterial isolates and Antibiotic Sensitivity Profile of asymptomatic bacterial urinary tract infection in pregnant women in selected clinics in Nairobi.Methods: This was a cross-sectional study involving women attending antenatal clinic at selected clinics of Nairobi County. The women who met the inclusion criteria were included in the study. The midstream urine samples of these women were subjected to microscopy, culture and sensitivity.Results: A total of 1020 of women on their first antenatal clinic visit participated in the study; 219 of them had ASB, giving a prevalence of 21.5 % at 95% confidence level. Escherichia coli were the common organism isolated at 38.8%. The majority of the organisms were sensitive to imipenem and gentamycin.Conclusion: There is a high prevalence of ASB among pregnant women included in the study from the Nairobi county clinics. Therefore, routine ASB screening of pregnant women is recommended among the women attending antennal clinics in Nairobi county clinics
