“…Maternal characteristics including age, parity, height, weight, body mass index (BMI in kg/m 2 , calculated using weight and height measured at antenatal booking), year of birth categorised into after 1983 (actual year of birth 1984–1998) or in/before (actual year of birth 1972–1983), presence of iron deficiency anaemia as surrogate for nutritional status, presence of any thalassaemia trait, and HBV status, were retrieved for analysis. We examined the impact of both high (≥25 kg/m 2 ) [ 24 ] and low (<18.5 kg/m 2 ) BMI [ 25 ], as well as short stature (< 151 cm) as a surrogate of nutritional status during childhood and adolescence. Thalassaemia traits are common in our locality [ 26 ], but its relationship with immune response to the MMR vaccine has not been examined so that this was examined to elucidate its role in the high incidence of rubella seronegativity.…”

ObjectiveThis study compared the incidence of rubella seronegativity among gravidae of 25 year-old and younger, between those born in Hong Kong after 1983 when the two-dose rubella vaccination was implemented, versus gravidae born before, to examine the impact of the two-dose regimen.MethodsIn this retrospective cohort study, the incidence of antenatal rubella seronegativity in our parturients managed in1997-2015 was analysed by their age from ≤16 to 25 years, and the effect of year of birth was determined adjusting for confounding factors including teenage status, obstetric history, anthropometric factors, and health parameters including anaemia, thalassaemia trait and hepatitis B carrier status.ResultsAmong the 12743 gravidae, the 6103 gravidae born after 1983 had overall higher rubella seronegativity (9.1% versus 4.4%, OR 2.061, 95% CI 1.797–2.364), with significant difference (p = 0.006) and inverse correlation (p<0.001) with age, in contrast to the 6640 gravidae born in/before 1983 whom there was significant difference (p = 0.027) but a positive correlation (p = 0.008) with age. For each year of age, the former had significantly higher incidence of rubella seronegativity except for those of ≤16 years. Regression analysis confirmed that birth after 1983 was independently associated with rubella seronegativity (aOR 2.207, 95% CI 1.902–2.562).ConclusionThere was a significant trend between rubella seronegativity with age in young gravidae, but the pattern was opposite between gravidae born after versus in/before 1983, with the former having a higher incidence of seronegativity at all ages. Young women covered by the two-dose rubella immunisation programme have a paradoxically higher incidence of rubella seronegativity.

Malaria and Hepatitis B Virus (HBV) infections are co-endemic throughout much of the tropical and sub-Saharan Africa and both present major threat to public health. A study on the prevalence of HBV and Malaria co-infection was carried out on 200 patients presenting with fever at the General Outpatient Department (GOPD) of the Murtala Muhammed Specialist Hospital (MMSH), Kano using Gold Standard microscopy and rapid diagnostic test (RDT). The effect of mono and co-infection on hematological parameters was also investigated. Fifty one (25.5%) out of the 200 patients studied were Malaria positive. Females had higher prevalence rate(18%) of Malaria infection than males with 7.5%. Age group 15-24 had the highest Malaria prevalence (11%) followed by age group 25-34 with 6.5%. Higher mean parasite density (1,200/µl) was recorded among subjects with monoinfection of Malaria than mean parasite density (518/µl) obtained among the co-infected. Mean parasite density was higher in female than male subjects. Thirteen (6.5%) subjects were HBV positive. Males had higher rate of infection with 4.5% prevalence than females with 2.0%. Nine individuals representing 4.5% of the total population had co-infection with higher prevalence (3%) among the males. Age groups 25-34 were observed to have high co-infection rate of 1.5% and the least prevalence was observed among the age group 15-24 with 0.5% prevalence for both males and females. Hematological evaluation carried out on all the categories of subjects shows significant difference in mean values of PCV (P=0.041), Hb (P=0.018) between the co-infection group and those with malaria infection and control groups. However, no significant difference (P>0.05) was observed in the values of WBC, PLT and Red cell indices among the co-infected and other test group. It was concluded that co-infection with the two ailments had no profound effect on hematologic parameters.
