RESUMEN
BACKGROUND: Improving maternal health has been a primary goal of international health agencies for many years, with the aim of reducing maternal and child deaths and improving access to antenatal care (ANC) services, particularly in low-and-middle-income countries (LMICs). Health interventions with these aims have received more attention from a clinical effectiveness perspective than for cost impact and economic efficiency. METHODS: We collected data on resource use and costs as part of a large, multi-country study assessing the use of routine antenatal screening ultrasound (US) with the aim of considering the implications for economic efficiency. We assessed typical antenatal outpatient and hospital-based (facility) care for pregnant women, in general, with selective complication-related data collection in women participating in a large maternal health registry and clinical trial in five LMICs. We estimated average costs from a facility/health system perspective for outpatient and inpatient services. We converted all country-level currency cost estimates to 2015 United States dollars (USD). We compared average costs across countries for ANC visits, deliveries, higher-risk pregnancies, and complications, and conducted sensitivity analyses. RESULTS: Our study included sites in five countries representing different regions. Overall, the relative cost of individual ANC and delivery-related healthcare use was consistent among countries, generally corresponding to country-specific income levels. ANC outpatient visit cost estimates per patient among countries ranged from 15 to 30 USD, based on average counts for visits with and without US. Estimates for antenatal screening US visits were more costly than non-US visits. Costs associated with higher-risk pregnancies were influenced by rates of hospital delivery by cesarean section (mean per person delivery cost estimate range: 25-65 USD). CONCLUSIONS: Despite substantial differences among countries in infrastructures and health system capacity, there were similarities in resource allocation, delivery location, and country-level challenges. Overall, there was no clear suggestion that adding antenatal screening US would result in either major cost savings or major cost increases. However, antenatal screening US would have higher training and maintenance costs. Given the lack of clinical effectiveness evidence and greater resource constraints of LMICs, it is unlikely that introducing antenatal screening US would be economically efficient in these settings--on the demand side (i.e., patients) or supply side (i.e., healthcare providers). TRIAL REGISTRATION: Trial number: NCT01990625 (First posted: November 21, 2013 on https://clinicaltrials.gov ).

OBJECTIVE: Limited data are available from low- and middle-income countries (LMICs) on the relationship of haemoglobin levels to adverse outcomes at different times during pregnancy. We evaluated the association of haemoglobin levels in nulliparous women at two times in pregnancy with pregnancy outcomes. DESIGN: ASPIRIN Trial data were used to study the association between haemoglobin levels measured at 6+0 -13+6 weeks and 26+0 -30+0 weeks of gestation with fetal and neonatal outcomes. SETTING: Obstetric care facilities in Pakistan, India, Kenya, Zambia, The Democratic Republic of the Congo and Guatemala. POPULATION: A total of 11 976 pregnant women. METHODS: Generalised linear models were used to obtain adjusted relative risks and 95% CI for adverse outcomes. MAIN OUTCOME MEASURES: Preterm birth, stillbirth, neonatal death, small for gestational age (SGA) and birthweight <2500 g. RESULTS: The mean haemoglobin levels at 6+0 -13+6 weeks and at 26-30 weeks of gestation were 116 g/l (SD 17) and 107 g/l (SD 15), respectively. In general, pregnancy outcomes were better with increasing haemoglobin. At 6+0 -13+6 weeks of gestation, stillbirth, SGA and birthweight <2500 g, were significantly associated with haemoglobin of 70-89 g/l compared with haemoglobin of 110-129 g/l The relationships of adverse pregnancy outcomes with various haemoglobin levels were more marked at 26-30 weeks of gestation. CONCLUSIONS: Both lower and some higher haemoglobin concentrations are associated with adverse fetal and neonatal outcomes at 6+0 -13+6 weeks and at 26-30 weeks of gestation, although the relationship with low haemoglobin levels appears more consistent and generally stronger. TWEETABLE ABSTRACT: Both lower and some higher haemoglobin concentrations were associated with adverse fetal and neonatal outcomes at 6-13 weeks and 26-30 weeks of gestation.

OBJECTIVE: Ultrasound is widely regarded as an important adjunct to antenatal care (ANC) to guide practice and reduce perinatal mortality. We assessed the impact of ANC ultrasound use at health centres in resource-limited countries. DESIGN: Cluster randomised trial. SETTING: Clusters within five countries (Democratic Republic of Congo, Guatemala, Kenya, Pakistan, and Zambia) METHODS: Clusters were randomised to standard ANC or standard care plus two ultrasounds and referral for complications. The study trained providers in intervention clusters to perform basic obstetric ultrasounds. MAIN OUTCOME MEASURES: The primary outcome was a composite of maternal mortality, maternal near-miss mortality, stillbirth, and neonatal mortality. RESULTS: During the 24-month trial, 28 intervention and 28 control clusters had 24 263 and 23 160 births, respectively; 78% in the intervention clusters received at least one study ultrasound; 60% received two. The prevalence of conditions noted including twins, placenta previa, and abnormal lie was within expected ranges. 9% were referred for an ultrasound-diagnosed condition, and 71% attended the referral. The ANC (RR 1.0 95% CI 1.00, 1.01) and hospital delivery rates for complicated pregnancies (RR 1.03 95% CI 0.89, 1.20) did not differ between intervention and control clusters nor did the composite outcome (RR 1.09 95% CI 0.97, 1.23) or its individual components. CONCLUSIONS: Despite availability of ultrasound at ANC in the intervention clusters, neither ANC nor hospital delivery for complicated pregnancies increased. The composite outcome and the individual components were not reduced. TWEETABLE ABSTRACT: Antenatal care ultrasound did not improve a composite outcome that included maternal, fetal, and neonatal mortality.

OBJECTIVE: We sought to classify causes of stillbirth for six low-middle-income countries using a prospectively defined algorithm. DESIGN: Prospective, observational study. SETTING: Communities in India, Pakistan, Guatemala, Democratic Republic of Congo, Zambia and Kenya. POPULATION: Pregnant women residing in defined study regions. METHODS: Basic data regarding conditions present during pregnancy and delivery were collected. Using these data, a computer-based hierarchal algorithm assigned cause of stillbirth. Causes included birth trauma, congenital anomaly, infection, asphyxia, and preterm birth, based on existing cause of death classifications and included contributing maternal conditions. MAIN OUTCOME MEASURES: Primary cause of stillbirth. RESULTS: Of 109 911 women who were enrolled and delivered (99% of those screened in pregnancy), 2847 had a stillbirth (a rate of 27.2 per 1000 births). Asphyxia was the cause of 46.6% of the stillbirths, followed by infection (20.8%), congenital anomalies (8.4%) and prematurity (6.6%). Among those caused by asphyxia, 38% had prolonged or obstructed labour, 19% antepartum haemorrhage and 18% pre-eclampsia/eclampsia. About two-thirds (67.4%) of the stillbirths did not have signs of maceration. CONCLUSIONS: Our algorithm determined cause of stillbirth from basic data obtained from lay-health providers. The major cause of stillbirth was fetal asphyxia associated with prolonged or obstructed labour, pre-eclampsia and antepartum haemorrhage. In the African sites, infection also was an important contributor to stillbirth. Using this algorithm, we documented cause of stillbirth and its trends to inform public health programs, using consistency, transparency, and comparability across time or regions with minimal burden on the healthcare system. TWEETABLE ABSTRACT: Major causes of stillbirth are asphyxia, pre-eclampsia and haemorrhage. Infections are important in Africa.

OBJECTIVE: To describe the causes of maternal death in a population-based cohort in six low- and middle-income countries using a standardised, hierarchical, algorithmic cause of death (COD) methodology. DESIGN: A population-based, prospective observational study. SETTING: Seven sites in six low- to middle-income countries including the Democratic Republic of the Congo (DRC), Guatemala, India (two sites), Kenya, Pakistan and Zambia. POPULATION: All deaths among pregnant women resident in the study sites from 2014 to December 2016. METHODS: For women who died, we used a standardised questionnaire to collect clinical data regarding maternal conditions present during pregnancy and delivery. These data were analysed using a computer-based algorithm to assign cause of maternal death based on the International Classification of Disease-Maternal Mortality system (trauma, termination of pregnancy-related, eclampsia, haemorrhage, pregnancy-related infection and medical conditions). We also compared the COD results to healthcare-provider-assigned maternal COD. MAIN OUTCOME MEASURES: Assigned causes of maternal mortality. RESULTS: Among 158 205 women, there were 221 maternal deaths. The most common algorithm-assigned maternal COD were obstetric haemorrhage (38.6%), pregnancy-related infection (26.4%) and pre-eclampsia/eclampsia (18.2%). Agreement between algorithm-assigned COD and COD assigned by healthcare providers ranged from 75% for haemorrhage to 25% for medical causes coincident to pregnancy. CONCLUSIONS: The major maternal COD in the Global Network sites were haemorrhage, pregnancy-related infection and pre-eclampsia/eclampsia. This system could allow public health programmes in low- and middle-income countries to generate transparent and comparable data for maternal COD across time or regions. TWEETABLE ABSTRACT: An algorithmic system for determining maternal cause of death in low-resource settings is described.

OBJECTIVE: To document the prevalence of malaria parasitaemia among the HIV infected febrile children in a malaria endemic area. DESIGN: A cross-sectional study. SETTING: An ambulatory paediatric HIV clinic in Western Kenya, between November 2011 and December 2012. SUBJECTS: A total of 245 febrile HIV infected children aged less than 14 years attending the HIV clinic in the Webuye level IV hospital were included in the study. A systematic sampling method was used. MAIN OUTCOMES: A blood sample was taken for malaria parasite testing. Presence or absence of malaria parasites was documented. Clinical and socio-demographic characteristics of the participants were also recorded. RESULTS: A total of 245 participants were recruited mean age being 5.53 years. Malaria prevalence was 81.9%. Most participants (97%) were on cotrimoxazole prophylaxis. Some of the factors found to be positively associated with malaria parasitaemia were; male sex, care taker category (parent), WHO stage 3 and 4 of HIV disease, and a high absolute CD4 count. However, only the caretaker association was statistically significant. CONCLUSION: The frequency of malaria parasitaemia among febrile HIV infected children is still high regardless of the high cotrimoxazole prophylaxis uptake. It is also noted that there is a shift in the age group of fever among children toward the older age group. This implies that policies may need to be relooked at to include the older age group in the aggressive malaria prevention measures to avoid losing on the already made gains.

BACKGROUND: Mortality of mothers and newborns is an important public health problem in low-income countries. In the rural setting, implementation of community based education and mobilization are strategies that have sought to reduce these mortalities. Frequently such approaches rely on volunteers within each community. OBJECTIVE: To assess the perceptions of the community volunteers in rural Kenya as they implemented the EmONC program and to identify the incentives that could result in their sustained engagement in the project. METHOD: A community-based cross sectional survey was administered to all volunteers involved in the study. Data were collected using a self-administered supervision tool from all the 881 volunteers. RESULTS: 881 surveys were completed. 769 respondents requested some form of incentive; 200 (26%) were for monetary allowance, 149 (19.4%) were for a bicycle to be used for transportation, 119 (15.5%) were for uniforms for identification, 88 (11.4%) were for provision of training materials, 81(10.5%) were for training in Home based Life Saving Skills (HBLSS), 57(7.4%) were for provision of first AID kits, and 39(5%) were for provision of training more facilitators, 36(4.7%) were for provision of free medication. CONCLUSION: Monetary allowances, improved transportation and some sort of identification are the main incentives cited by the respondents in this context.

OBJECTIVES: To determine the prevalence of malnutrition among children admitted with acute diarrhoea disease at Moi Teaching and Referral Hospital and to establish the effect of malnutrition on duration of hospital stay. DESIGN: Prospective observational study. SETTING: Paediatric wards of Moi Teaching and Referral Hospital, Eldoret, Kenya. SUBJECTS: A total of 191 children aged 6 and 59 months admitted with acute diarrhoea disease, without chronic co-morbidities or visible severe malnutrition, were systematically enrolled into the study between November 2011 and March 2012. OUTCOME MEASURES: Nutritional status based on WHO WHZ scores taken at admission and duration of hospital stay. RESULTS: The mean age was 13.2 months with a male to female sex ratio of 1.16:1. Of all the children seen with acute diarrhoeal diseases, 43.9% had acute malnutrition (<-2 WHZ score), with 12% being severely malnourished (<-3 Z score). Average duration of hospital stay was 3.36 (SD=1.54) days. Among those with malnutrition the average duration of stay was 3.39 (SD=1.48) days while for those without malnutrition it was 3.21(SD=1.20) days, which was not statistically different. No death was reported. WHO weight for Height Z scores picked 12% of severe form of malnutrition missed out by Welcome Trust classification (weight for age). CONCLUSION: Routine anthrometry including weight for height identifies more children with malnutrition in acute diarrhoeal diseases. Presence of malnutrition did not affect duration of hospital stay.

OBJECTIVES: To determine the current status of immunisation coverage in Western Kenya before intervention, to identify strengths and weaknesses of the existing programme in order to design educational interventions that could improve the services provided and find out the training needs of the mid-level managers of Kenya Expanded Programme of Immunisation. DESIGN: Cross-sectional descriptive study. SETTING: All thirty nine districts in Rift Valley, Western and Nyanza provinces. SUBJECTS: Mid-level managers of Kenya Expanded Programme on Immunisation in the 39 districts and the provinces. These included Provincial Logisticians, Provincial Medical Officers of Health, District Medical Officers of Health, District Public Health Nurses, District Records and Health Information Officers, District Disease Surveillance Officers, and District Public Health Officers. MAIN OUTCOME MEASURES: Number of staff trained on EPI, coverage rates and perceived training needs of the mid-level managers. RESULTS: A total of eighty eight mid-level managers participated in the interviews. Most of these were District Public Health Nurses (40.9%) and District Health Information and Records Officers (23.9%). Only 49 (25%) of the District Health Management Team members had undergone training at the supervisory level. Eighteen districts (43.6%) had no member of the District Health Management Team that had ever been trained at the supervisory level. Using rates of Pentavalent 1 and measles coverage, Nyanza Province had the highest immunisation dropout rate (Pentavalent 1--measles) whereas Rift Valley Province had the lowest. The annual cumulative coverage for all the provinces by antigen was 80% for Pentavalent 1 and 2 and 60% for measles. The most requested need for inclusion in the training curriculum was maintenance of the cold chain equipment. CONCLUSIONS: Most of the members in the study area have not been trained on Expanded Programme on Immunisation and may be ill-equipped to manage the complicated programmes needed to maximise delivery of services. The immunisation coverage in this area is low while the dropout rates are high. We therefore recommend that all the mid-level managers of Expanded Programme on Immunisation in this area be trained comprehensively through the Merck Vaccine Network--Africa programme using the World Health Organisation approved mid-level managers course.

Phase I of the International Study of Asthma and Allergies in Childhood has provided valuable information regarding international prevalence patterns and potential risk factors in the development of asthma, allergic rhinoconjunctivitis and eczema. However, in Phase I, only six African countries were involved (Algeria, Tunisia, Morocco, Kenya, South Africa and Ethiopia). Phase III, conducted 5-6 years later, enrolled 22 centres in 16 countries including the majority of the centres involved in Phase I and new centres in Morocco, Tunisia, Democratic Republic of Congo, Togo, Sudan, Cameroon, Gabon, Reunion Island and South Africa. There were considerable variations between the various centres of Africa in the prevalence of the main symptoms of the three conditions: wheeze (4.0-21.5%), allergic rhinoconjunctivitis (7.2-27.3%) and eczema (4.7-23.0%). There was a large variation both between countries and between centres in the same country. Several centres, including Cape Town (20.3%), Polokwane (18.0%), Reunion Island (21.5%), Brazzaville (19.9%), Nairobi (18.0%), Urban Ivory Coast (19.3%) and Conakry (18.6%) showed relatively high asthma symptom prevalences, similar to those in western Europe. There were also a number of centres showing high symptom prevalences for allergic rhinoconjunctivitis (Cape Town, Reunion Island, Brazzaville, Eldoret, Urban Ivory Coast, Conakry, Casablanca, Wilays of Algiers, Sousse and Eldoret) and eczema (Brazzaville, Eldoret, Addis Ababa, Urban Ivory Coast, Conakry, Marrakech and Casablanca).

OBJECTIVE: To evaluate hepatitis B serological markers in pregnant women from various geographical sites in Kenya. DESIGN: A cross-sectional observational study of women attending antenatal clinics. SETTING: The Kenyatta National Hospital and eight hospitals from five provinces in Kenya. SUBJECTS: All women in their third trimester of pregnancy attending the antenatal clinic over the period June 2001 to June 2002. MAIN OUTCOME MEASURES: For each pregnant woman age and gestation were documented. Hepatitis serological markers were evaluated. RESULTS: A total of 2241 pregnant women were enrolled. Among them 205 women (9.3%) were positive for HbsAg and from these 18 (8.8%) were found to have HbeAg. Protective antibodies (anti-HbsAg) were detected in 669 (30.2%) of the women. There were notable significant regional differences for HbsAg rates. CONCLUSIONS: These results confirm the presence of high disease carrier rate and the corresponding previously reported low level of HbeAg suggesting questionable low rate of perinatal transmission but high rate of horizontal transmission.

BACKGROUND: In sub-Saharan Africa, the practice of breast-feeding infants is common. Records documenting the intake of breast milk amongst infants are limited. This study evaluated the association between maternal body composition and the intake of breast milk in infants from the pastoral communities within Pokot, Kenya. METHODS: The study was conducted in 10 lactating mothers who were participating in a longitudinal study aimed at determining maternal body composition, iron stores and vitamin A status during the third trimester pregnancy and four months after they had given birth. Maternal and infant anthropometric measurements were made, and maternal blood samples were taken to determine serum retinol and ferritin levels. Infant milk intake and maternal fat-free mass (FFM) and percent body fat (% BF) were measured using 'the dose to the mother method'. A measured deuterium oxide ((2)H(2)O) dose was given to the mother. Urine and breast milk from the mother, and saliva samples from the infant, were collected on days 1, 8 and 14 after dosing. RESULTS: The mean (+/- SD) maternal mid upper arm circumference (MUAC) and body mass index (BMI) were 21.8 (0.9) cm and 18.6 (1.0) kg/height (m(2)), respectively. Infant weight and weight/age Z score were 4.956 (0.874) kg and -1.750 (0.77), respectively. Throughout the study, the infants gained 20 (4) g/day in body weight and had a milk intake of 555 (22) ml/day. The energy intake of the infant was 1,602 (148) kJ/day and was lower (p < 0.05) than the 2,404 (423) kJ/day estimated requirement by the FAO/WHO/UNU. The maternal FFM, %BF, Hb, Hct, ferritin and retinol were 32.8 (3.1) kg, 17.24 (7.0), 11.5 (1.3) g/dl, 33.9 (4.9), 16.2 (0.1) microg/l and 0.894 (0.16) micromol/l, respectively. Infant milk intake was significantly and positively correlated to maternal pregnancy triceps (r = 0.679) p < 0.05) and pregnancy MUAC (r = 0.725) p < 0.05). Maternal pregnancy MUAC was an important predictor of infant breast milk intake. CONCLUSION: Data on volume of breast milk consumed by the infants suggests, at least for this group of infants, that adequate growth may not be achieved. There is a possibility that lactating mothers practicing exclusive breast-feeding and living under harsh conditions may experience periods of low breast milk volume. Body composition and biochemical findings among this group of Pokot mothers indicate dietary inadequacies that require nutritional intervention.

The treatment of patients with severe malaria in sub-Saharan Africa has become a challenge to clinicians due to poor compliance to quinine and the increasing multidrug resistance to antimalarials by the P. falciparum parasite. The aim of this study was to compare the efficacy and safety profile of two truncated antimalarial regimens of intravenous quinine followed by oral Malarone (Malarone arm) with intravenous quinine followed by oral quinine (quinine arm) in the treatment of severe P. falciparum malaria. The outcome measures were parasite clearance time, fever clearance time, efficacy, and adverse events profile. Consecutive patients aged 1-60 years, with a diagnosis of severe malaria with positive blood smears for P. falciparum parasites and admitted to the Moi Teaching and Referral Hospital were randomized into the two study arms. Of the 360 patients studied 167 and 193 cases were randomized into the Malarone and quinine arms, respectively. Of the five (1.4 per cent) patients who died, three came from the quinine arm. The frequency of adverse reactions was higher in the oral quinine group (31.6 per cent) than in the Malarone group (25.7 per cent). The mean parasite clearance time was 120 h and 108 h for the quinine and Malarone arms of the study, respectively, and the mean fever clearance times were 84 h and 72 h for the quinine and Malarone arms, respectively (p=0.1). Truncated therapeutic regimen using malarone after intravenous quinine is safer and as effective as conventional intravenous quinine followed by oral quinine in the treatment of severe malaria. The P. falciparum recrudescence rate was lower with the use of Malarone than for quinine.

BACKGROUND: Malnutrition is one of the leading causes of morbidity and mortality in children aged five years and below. Risk factors for severe protein energy malnutrition (PEM) have been identified as ignorance, family size, mothers and fathers education, poverty, residence, chronic infections, and congenital defects or malformations. The role of such social factors as the caretaker, extended family, homestead surroundings, and family cohesiveness have not been studied in Kenya. OBJECTIVE: To determine the social and economic factors that predispose children to severe PEM as seen at the Moi Teaching and Referral Hospital (MTRH), Eldoret. DESIGN: Prospective and case control study. SETTING: The MTRH, Eldoret, Paediatric wards, outpatient and MCH clinics over a 12 month period (June 2001 to June 2002). SUBJECTS: Sixty six children aged 3 to 36 months with severe PEM attending the MTRH outpatient clinics and those admitted in the Paediatric wards were age-matched with 66 controls. METHODS: A standard pretested questionnaire was used to interview caretakers with severely malnourished children and age-matched controls. The children were weighed after interviewing the caretakers. The data was entered on a computer and analysed using the statistical package for social sciences (SPSS) programme. RESULTS: The social risk factors for PEM were single mothers (Odds Ratio) OR 14.93, p= 0.00001), young mothers aged 15-25 years (OR 3.95, p= 0.00020), the child's living conditions such as living in a temporary house (OR 3.627 p= 0.00257), caretaker who was not married to the child's parent (OR 0.10, p= 0.00005) and not staying with both parents in the past six months (OR 0.28606, p=0.00101). The economic risk factors were father's lack of ownership of land (OR 0.401, p= 0.01732), cattle (OR 0.24, p=0.00022), not growing maize (OR 0.15, p=0.00013), not growing beans (OR 0.36, p=0.00484) and ownership of small piece of land by grandfather (OR 6.00, p= 0.02274). Other risk factors were incomplete immunization (OR 3.87, p= 0.00151) and female sex (p=0.03721). CONCLUSION: Poverty, social conditions under which the child was living, sex of the child and incomplete immunizations were risk factors for the severe protein energy malnutrition.

OBJECTIVES: To determine the mortality rate and causes of death of all infants admitted to the Special Care Nursery (SCN) of a tertiary referral hospital in rural Kenya. DESIGN: Prospective and Cross-sectional study SETTING: Special Care Nursery, Moi Teaching and Referral Hospital, Eldoret, Kenya. SUBJECTS: All infants admitted to the Special Care Nursing (SCN). MAIN OUTCOME MEASURES: Survival status at seven postnatal days; major causes of mortality and morbidity. RESULTS: Three hundred and thirty five babies were studied between February and September 1999. Out of these 167 (49.9%) were male. There were 50 (15%) preterm and 124 (37.3%) low birth weight babies. There were 198 (76.2%) appropriate for gestational age (AGA), 46 (17.7%) small for gestational age and 16 (6.2%) large for gestational age babies. The seven day mortality rate of infants admitted to the Special Care Nursery was 66 (19.7%). Birth asphyxia and respiratory distress accounted for most deaths. Infants who were admitted primarily because the mother remained under general anesthesia generally did well. Logistic factors, including inadequate training for neonatal resuscitation in ward cadre of staff, unavailability of trained paediatricians and obstetricians, and inadequate operating theatre supplies were all found to delay treatment and likely to increase mortality. CONCLUSION: Morbidity and mortality of infants born at the MTRH remain high. The most common cause of mortality remains birth asphyxia. Some causative factors, such as lack of resources or personnel, are logistic and could be rectified. Antenatal care had a significant positive impact on both morbidity and mortality.

OBJECTIVE: To understand the natural history of HIV-1 infection in children in terms of evolution of childhood clinical manifestations versus the immune status, we prospectively studied children with and without maternally transmitted HIV-1 infection born to mothers infected with HIV-1 for two years between March 1998 and March 2000. DESIGN: A prospective cohort study. SETTING: An institutional children's home. SUBJECTS: Fifty nine children (26 males and 33 females) with and without maternally transmitted HIV-1 infection born to mothers infected with HIV-1 and adopted in institutional children home. METHODS: HIV-1 status of children under nine months was confirmed by polymerase chain reaction(PCR). ELISA for HIV-1 antibody in serum/plasma was used to confirm HIV-infection status for children aged < or = 18 months. Children were visited every three months between March and June 2000. At every visit blood was collected for total white cell count, haemoglobin and CD4+ and CD8+ T cell counts. The institutional doctor routinely examined children and treated all ailments. Clinical data were recorded. MEASURES: HIV-DNA, anti-HIV antibodies, total white blood count, total T cell counts, CD4 and CD8 T cell subset counts, frequency of childhood manifestations of infection. RESULTS: The children were aged between 4.5 and 13 years. The baseline haematological and immunological profiles (mean, mode) were: HIV-1 sero-converters (WBC 7151,7150; HB 11.6, 12.0; CD4+ 686, 795; CD8+ 2168, 1507) and HIV-1 de-seroconverters (mean, mode) were: (WBC 8386, 7150; HB 11.7, 12.8; CD4+ 735, 795; CD8+ 2168, 1507). The commonest causes of illnesses among the HIV-1 children were URTI (85.3%), TB(56.1 %), pneumonia (56.2%), tonsillitis (34.1%), parotiditis (28%) and acute otitis media (25%). The distribution of clinical manifestations was similar between the two categories of children, except URTI, whose prevalence was significantly increased among HIV-1 infected children (p-value=0.006). Among the HIV-1 infected children, only TB, parotiditis, and acute otitis media (AOM) were significantly associated with decreased CD4+ T cell count (p<0.05) resulting from HIV infection. CONCLUSIONS: HIV infection in children predisposes them to common childhood infections that can be used as markers of immune decline. TB, AOM, URTI may be early indicators of suspicion that would enable selective screening for HIV infection in children.

OBJECTIVE: To establish the relative increase in the prevalence of asthma, allergic rhinitis and eczema in primary school children aged 13-14 years over a six year interval. DESIGN: Cross sectional comparative study. SETTING: Primary schools in three rural divisions at Uasin Gishu district in the Rift Valley Province of Kenya. METHODS: Three thousand two hundred and fifty eight children aged 13-14 years from seventy two primary schools in Uasin Gishu district were studied using the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. All children in the selected schools in this age range whose parents gave consent were included. RESULTS: There were 47.4% males and 52.6% females as compared to 48.7% and 51.3% respectively in 1995. The cumulative prevalence for wheezing, rhinitis, itchy eyes and dermatitis was 23.6%, 43%, 24.1% and 28.5% respectively which were higher than for 1995 which were 21.2%, 32.4%, 11.8% and 13.8% respectively (p = 0.001). The period prevalence rates for wheezing, rhinitis and eczema were 13.8%, 31.4% and 21.3% respectively as compared to 10.2%, 25.3% and 14.4% respectively for 1995 (p = 0.001). The prevalence of asthma, allergic rhinitis and eczema was 12.6%, 38.6% and 28.5% respectively in 2001 compared to 6.6%, 14.9% and 13.9% respectively in 1995 (p = 0.001). CONCLUSION: There was a significant increase in the prevalence of asthma, allergic rhinitis and eczema in children in the study population over the last six years.

A prospective study was carried out in which brain, core and skin temperatures were studied in children with cerebral malaria (n = 23), uncomplicated malaria (n = 12) and normal children (n = 9) using the zero heat flow method. Patients with cerebral or uncomplicated malaria were admitted to the paediatric wards (mean age, 6 years 8 months +/- 2 years 8 months). Normal children, children of the investigators, of the same age group, served as controls. Parasitaemia levels were similar in the cerebral and uncomplicated malaria cases. Higher brain than core temperatures would have been expected in cerebral malaria but not in uncomplicated malaria but this was not the case in this study. There was no statistical difference in brain, core and skin temperature between cerebral and uncomplicated malaria patients. However, there was a highly significant difference between normal children and cerebral and uncomplicated malaria patients. Brain temperature was 0.02-0.2 degrees C below core temperature in all the groups with larger differences during the febrile period. Mean differences of brain minus core, brain minus skin and core minus skin between the two groups of patients were not statistically significant. There was no correlation between temperature and the level of coma or parasitaemia for cerebral and uncomplicated malaria patients. There was a positive correlation between brain and core temperature in both groups of patients during the febrile phase. Brain temperature remained lower than core temperature in cerebral and uncomplicated malaria as in normal children. Normal thermoregulation appears to be maintained in cerebral malaria.

BACKGROUND: Perinatal morbidity (PNM) is highest in the developing countries including Kenya. Studies on the perinatal morbidity in Moi Teaching and Referral Hospital (MTRH) have not been carried out. Furthermore, factors associated with PNM are unknown at the MTRH. OBJECTIVE: To establish the causes and incidence of perinatal morbidity at the MTRH NewBorn Unit (NBU). DESIGN: A retrospective study using case notes. SETTING: The NBU of the MTRH in Eldoret, Kenya. SUBJECTS: Babies who were admitted to the MTRH's Newborn Unit from January to December 1997. RESULTS: The perinatal morbidity was 667 per 1000 babies admitted to the NBU. The most common reason for admission was mother under anaesthesia. The most common cause of morbidity was asphyxia. The mean maternal age was 24 years. The mean level of education was 1.7 years. More than fifty five per cent of the mothers were housewives. The mean birthweight was 2.75 kg (+/- 0.9 SD), 55.9% had normal birthweight, 37% were low birthweight and three per cent were large babies. The mean duration of stay in the NBU was 3.8 days. CONCLUSION: Most of the admissions were Caesarean section babies who did not require admission. Younger mothers were more likely to have babies with neonatal sepsis, convulsions, pneumonia and asphyxia.

BACKGROUND: The street children phenomenon is an increasing problem in most cosmopolitan cities of the world including Eldoret, which is a fast growing town. With the growth of the town so is the increasing number of street children. It is therefore important to have baseline data on their health problems. OBJECTIVE: To determine the health problems of street children in Eldoret. DESIGN: A prospective and descriptive study. SETTING: Eldoret Town, Kenya. SUBJECTS: Eldoret street children aged 5-21 years. Type 1 street children were the "on" the street children who spent most of their time on the streets but went home in the evenings, type 2 were the "of" the street children who spent all their time in the streets and had severed their links with their families and did not have a home to go to, type 3 were abandoned children staying in a shelter and type 4 were normal primary school children. RESULTS: One hundred and ninety one children were studied. There were 38, 47, 56 and 50 types 1, 2, 3 and 4 children, respectively. The most common symptom was cough (28.9%) while frequent diagnosis was upper respiratory tract infection (URTI) (12.1%) followed by skin disease (50.9%) as the leading disease category. The common drug of addiction was cigarette (37.6%) and none of the school children was taking any drug of addiction. The prevalence of disease was 467 per 1000 children. Type 2 street children had the highest prevalence of disease (833 per 1000 children). Shelter children had the least disease prevalence (474 per 1000). Factors determining prevalence of disease were the same as in normal children. The malnutrition rate was high with 31.1% and 41.9% of the children being stunted and underweight, respectively. Type 3 children had the highest rate of malnutrition with 51.8% and 64.3% being stunted and underweight. CONCLUSION: Street children have a high incidence of childhood diseases. Factors determining occurrence of disease among street children are as in normal children. Respiratory and skin diseases were the leading causes of morbidity. Drug abuse was rampant among the street children but none of the school children abused any drug. Sexually transmitted infections were not prevalent. Most of the shelter children were malnourished. RECOMMENDATIONS: The government of Kenya should provide free health care for street children in public hospitals. Further studies should be carried out on the prevalence of sexually transmitted diseases based on laboratory testing and on the causes of the injuries suffered by the street children. The reasons for the poor nutritional status of the shelter children should be analysed and appropriate measures taken.
