Introduction strong PMTCT-ART service linkages ensure continuity of care for healthier mothers and children born HIV free. Program data showed weak PMTCT- ART linkages in military health facilities. We conducted a study to assess the PMTCT-adult ART service linkage in two Nigerian military health facilities in Kaduna State. Methods we conducted a cross-sectional study using mixed methods (interviews and FGDs) in 44 Nigeria Army Reference Hospital (NARH) and 1 Division Hospital, Kaduna. We studied 372 HIV-positive mothers after a delivery of their babies, referred for ART services from January 2009 to December 2013. We conducted FGDs among ANC, PMTCT and ART clinics staff. We analysed data using descriptive and inferential methods. A p-value of < 0.05 was considered significant with 95% confidence intervals (CI) for estimates. Results of the 372 respondents studied, 320 (86%) accessed PMTCT services from the 44 NARH. Most respondents (206,55.4%) respondents aged < 25 years. One in six (16.7%) respondents had no record of referral. Delivering baby in a separate facility from where PMTCT services were accessed, increased the likelihood of not accessing ART services (odd ratio [OR]: 6.7, 95% CI= 3.3 -13.6). The qualitative study identified poor service integration between PMTCT and ANC clinics. Conclusion the key factors hindering PMTCT-ART linkage in military health facilities included poor service integration, clients delivering of a baby in a facility separate from where PMTCT services were accessed. The Ministry of Defence HIV programme should strengthen ANC-PMTCT-ART service integration through a centrally coordinated client information management system.

Background Haematological reference values are necessary for accurate diagnosis of diseases, clinical decision-making, treatment monitoring and clinical research. Due to unavailability of pan-Nigerian reference values, local results interpretation is based on the use of Western values. Objective This study aims to establish national reference values for some haematological parameters in apparently healthy young adult Nigerians. Methods Seven Thousand, Seven Hundred and Ninety-Seven (7,797) volunteers aged 18 to 26 years participated in the study. Participants’ interviewer-administered questionnaires and blood samples were collected, analyzed and those with confounding factors (HIV infection, Hepatitis B sero-positivity, Malaria and Pregnancy) were excluded from statistical analysis. The 95-percentile reference range was determined for each haematological parameter using SPSS Version 16 ® . The result obtained was reviewed with reference to already established reference values in two West African and Western countries. Results Blood specimens from 6153 (78.9%) participants [comprising 5915 (96.1%) males and 238 (3.9%) females] were analyzed after exclusion of 1,644 (21.1%) participants with confounding variables. Reference ranges among males and females varied and these were consistent with findings from two other West African countries. The median platelets count in this study was 218 x 10 9 /l while commonly used Western value is 280 x 10 9 /l. Other haematological parameters in the study were similar to Western values. Conclusion The findings of this study will improve clinical and research decision-making. Considering that this study is limited to young adult participants, there is a need to conduct future pan-Nigerian studies that will include all age groups.

We observed a high virological suppression rate among the study participants. However, a large proportion of virologically unsuppressed clients had identifiable resistance mutations. The study demonstrates that viral load monitoring is feasible at Nigerian military hospitals and supports the current WHO HIV treatment guidelines which emphasize virological monitoring of patients on ART for early detection of treatment failure.

Background Reference intervals are assessment tools for interpretation of clinical test results. These intervals describe the dispersion of test parameter values of apparently healthy persons in defined populations as health status indicators. Using reference intervals obtained and validated in populations outside the geographical region of derivation for medical decision-making may impact negatively on clinical interpretation and patient management. Many countries have established their reference values, current studies on these data for Nigeria are however scarce. Determination of clinical biochemistry reference intervals for young Nigerian adults which is of particular importance in routine clinical management and conduct of clinical trials in response to existing and emerging diseases will add significantly to the existing body of knowledge. Objective The objective was to establish reference intervals for 24biochemistry analytes among Nigerians aged 18 to 26 years. Methods This was a cross-sectional study among 7,797 consenting male and female military applicants aged 18 to 26 years from 37 States of Nigeria. It was a total study among volunteers for military service. Blood samples were collected and subjected to serological testing for HIV-1 and 2, hepatitis-B, malaria, pregnancy and haematuria to restrict our study population to apparently healthy participants. Biochemical assays were performed on 6,169 participant samples that met the inclusion criteria. Generated data was entered into MS Excel® and exported into SPSS® software version 16 for analysis. Statistical tools used were frequencies, median, mid 95th percentile range with 2.5th and 97.5th percentiles as limits. Reference intervals were estimated using nonparametric methods. No intergender statistical comparison was made. Results Complete records were obtained for 6,169 eligible participants. Median values and associated reference intervals were similar in both genders. Conclusion The findings from this study will help in clinical decision-making and play a significant role in supporting the current global rapid expansion of clinical trials in response to the urgent need for preventive and therapeutic solutions to existing and emerging diseases.
