Point-of-care testing and treatment of sexually transmitted and genital infections to improve birth outcomes in high-burden, low-resource settings (WANTAIM): a pragmatic cluster randomised crossover trial in Papua New Guinea. Lancet Glob Health 2024; 12:e641-e651. [PMID: 38485431 DOI: 10.1016/s2214-109x(24)00004-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2023] [Revised: 12/13/2023] [Accepted: 01/02/2024] [Indexed: 03/19/2024]
Abstract
BACKGROUND Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, and bacterial vaginosis have been associated with adverse maternal and perinatal outcomes, but there is conflicting evidence on the benefits of antenatal screening and treatment for these conditions. We aimed to determine the effect of antenatal point-of-care testing and immediate treatment of C trachomatis, N gonorrhoeae, T vaginalis, and bacterial vaginosis on preterm birth, low birthweight, and other adverse maternal and perinatal outcomes compared with current standard of care, which included symptom-based treatment without laboratory confirmation. METHODS In this pragmatic cluster randomised crossover trial, we enrolled women (aged ≥16 years) attending an antenatal clinic at 26 weeks' gestation or earlier (confirmed by obstetric ultrasound), living within approximately 1 h drive of a study clinic, and able to provide reliable contact details at ten primary health facilities and their catchment communities (clusters) in Papua New Guinea. Clusters were randomly allocated 1:1 to receive either the intervention or control (standard care) in the first phase of the trial. Following an interval (washout period) of 2-3 months at the end of the first phase, each cluster crossed over to the other group. Randomisation was stratified by province. Individual participants were informed about trial group allocation only after completing informed consent procedures. The primary outcome was a composite of preterm birth (livebirth before 37 weeks' gestation), low birthweight (<2500 g), or both, analysed according to the intention-to-treat population. This study is registered with ISRCTN Registry, ISRCTN37134032, and is completed. FINDINGS Between July 26, 2017, and Aug 30, 2021, 4526 women were enrolled (2210 [63·3%] of 3492 women in the intervention group and 2316 [62·8%] of 3687 in the control group). Primary outcome data were available for 4297 (94·9%) newborn babies of 4526 women. The proportion of preterm birth, low birthweight, or both, in the intervention group, expressed as the mean of crude proportions across clusters, was 18·8% (SD 4·7%) compared with 17·8% in the control group (risk ratio [RR] 1·06, 95% CI 0·78-1·42; p=0·67). There were 1052 serious adverse events reported (566 in the intervention group and 486 in the control group) among 929 trial participants, and no differences by trial group. INTERPRETATION Point-of-care testing and treatment of C trachomatis, N gonorrhoeae, T vaginalis, and bacterial vaginosis did not reduce preterm birth or low birthweight compared with standard care. Within the subgroup of women with N gonorrhoeae, there was a substantial reduction in the primary outcome.

Abstract
INTRODUCTION Left untreated, sexually transmitted and genital infections (henceforth STIs) in pregnancy can lead to serious adverse outcomes for mother and child. Papua New Guinea (PNG) has among the highest prevalence of curable STIs including syphilis, chlamydia, gonorrhoea, trichomoniasis and bacterial vaginosis, and high neonatal mortality rates. Diagnosis and treatment of these STIs in PNG rely on syndromic management. Advances in STI diagnostics through point-of-care (PoC) testing using GeneXpert technology hold promise for resource-constrained countries such as PNG. This paper describes the planned economic evaluation of a cluster-randomised cross-over trial comparing antenatal PoC testing and immediate treatment of curable STIs with standard antenatal care in two provinces in PNG. METHODS AND ANALYSIS Cost-effectiveness of the PoC intervention compared with standard antenatal care will be assessed prospectively over the trial period (2017-2021) from societal and provider perspectives. Incremental cost-effectiveness ratios will be calculated for the primary health outcome, a composite measure of the proportion of either preterm birth and/or low birth weight; for life years saved; for disability-adjusted life years averted; and for non-health benefits (financial risk protection and improved health equity). Scenario analyses will be conducted to identify scale-up options, and budget impact analysis will be undertaken to understand short-term financial impacts of intervention adoption on the national budget. Deterministic and probabilistic sensitivity analysis will be conducted to account for uncertainty in key model inputs. ETHICS AND DISSEMINATION This study has ethical approval from the Institutional Review Board of the PNG Institute of Medical Research; the Medical Research Advisory Committee of the PNG National Department of Health; the Human Research Ethics Committee of the University of New South Wales; and the Research Ethics Committee of the London School of Hygiene and Tropical Medicine. Findings will be disseminated through national stakeholder meetings, conferences, peer-reviewed publications and policy briefs. TRIAL REGISTRATION NUMBER ISRCTN37134032.

Abstract
Background: Chlamydia trachomatis,
Neisseria gonorrhoeae,
Trichomonas vaginalis and bacterial vaginosis have been associated with preterm birth and low birth weight, and are highly prevalent among pregnant women in many low- and middle-income settings. There is conflicting evidence on the potential benefits of screening and treating these infections in pregnancy. Newly available diagnostic technologies make it possible, for the first time, to conduct definitive field trials to fill this knowledge gap. The primary aim of this study is to evaluate whether antenatal point-of-care testing and immediate treatment of these curable sexually transmitted and genital infections (STIs) leads to reduction in preterm birth and low birth weight. Methods: The Women and Newborn Trial of Antenatal Interventions and Management (WANTAIM) is a cluster-randomised crossover trial in Papua New Guinea to compare point-of-care STI testing and immediate treatment with standard antenatal care (which includes the WHO-endorsed STI ‘syndromic’ management strategy based on clinical features alone without laboratory confirmation). The unit of randomisation is a primary health care facility and its catchment communities. The primary outcome is a composite measure of two events: the proportion of women and their newborns in each trial arm, who experience either preterm birth (delivery <37 completed weeks of gestation as determined by ultrasound) and/or low birth weight (<2500 g measured within 72 hours of birth). The trial will also evaluate neonatal outcomes, as well as the cost-effectiveness, acceptability and health system requirements of this strategy, compared with standard care. Conclusions: WANTAIM is the first randomised trial to evaluate the effectiveness, cost-effectiveness, acceptability and health system requirements of point-of-care STI testing and treatment to improve birth outcomes in high-burden settings. If the intervention is proven to have an impact, the trial will hasten access to these technologies and could improve maternal and neonatal health in high-burden settings worldwide.

Abstract
BACKGROUND Prevention of parent-to-child transmission (PPTCT) of HIV is a highly complex package of interventions, which spans services in both maternal and child health programmes. In Papua New Guinea (PNG), a commitment to ensure that all pregnant women and their partners have access to the full range of PPTCT interventions exists; however, efforts to increase access and utilisation of PPTCT remain far from optimal. The aim of this paper is to examine health care worker (HCW) perception of health system factors impacting on the performance of PPTCT programmes. METHOD Sixteen interviews were undertaken with HCWs involved in the PPTCT programme. Application of the WHO 6 building blocks of a health system was applied, and further thematic analysis was conducted on the data with assistance from the analysis software NVivo. RESULTS Broken equipment, problems with access to medication and supplies, and poorly supported workforce were reported as barriers for implementing a successful PPTCT programme. The absence of central coordination of this complex, multistaged programme was also recognised as a key issue. CONCLUSION The study findings highlight an important need for investment in appropriately trained and supported HCWs and integration of services at each stage of the PPTCT programme. Lessons from the PPTCT experience in PNG may inform policy discussions and considerations in other similar contexts.

Abstract
Background Sexually transmitted and genital infections in pregnancy are associated with an increased risk of adverse maternal and neonatal health outcomes. High prevalences of sexually transmitted infections have been identified among antenatal attenders in Papua New Guinea. Papua New Guinea has amongst the highest neonatal mortality rates worldwide, with preterm birth and low birth weight major contributors to neonatal mortality. The overall aim of our study was to determine if a novel point-of-care testing and treatment strategy for the sexually transmitted and genital infections Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Trichomonas vaginalis (TV) and Bacterial vaginosis (BV) in pregnancy is feasible in the high-burden, low-income setting of Papua New Guinea. Methods Women attending their first antenatal clinic visit were invited to participate. CT/NG and TV were tested using the GeneXpert platform (Cepheid, USA), and BV tested using BVBlue (Gryphus Diagnostics, USA). Participants received same-day test results and antibiotic treatment as indicated. Routine antenatal care including HIV and syphilis screening were provided. Results Point-of-care testing was provided to 125/222 (56 %) of women attending routine antenatal care during the three-month study period. Among the 125 women enrolled, the prevalence of CT was 20.0 %; NG, 11.2 %; TV, 37.6 %; and BV, 17.6 %. Over half (67/125, 53.6 %) of women had one or more of these infections. Most women were asymptomatic (71.6 %; 47/67). Women aged 24 years and under were more likely to have one or more STI compared with older women (odds ratio 2.38; 95 % CI: 1.09, 5.21). Most women with an STI received treatment on the same day (83.6 %; 56/67). HIV prevalence was 1.6 % and active syphilis 4.0 %. Conclusion Point-of-care STI testing and treatment using a combination of novel, newly-available assays was feasible during routine antenatal care in this setting. This strategy has not previously been evaluated in any setting and offers the potential to transform STI management in pregnancy and to prevent their associated adverse health outcomes.

Abstract
Maternal or neonatal tetanus causes deaths primarily in Asia and Africa and is usually the result of poor hygiene during delivery. In 2011, three neonatal tetanus cases were investigated in Papua New Guinea, and all three cases were delivered at home by untrained assistants. The babies were normal at birth but subsequently developed spasms. A neonatal tetanus case must be viewed as a sentinel event indicating a failure of public health services including immunization, antenatal care and delivery care. The confirmation of these cases led to the drafting of the Papua New Guinea National Action Plan for Maternal and Neonatal Tetanus Elimination. This included three rounds of a tetanus toxoid supplementary immunization campaign targeting women of childbearing age (WBCA) and strengthening of other clean delivery practices. The first immunization round was conducted in April and May 2012, targeting 1.6 million WBCA and achieved coverage of 77%. The government of Papua New Guinea should ensure detailed investigation of all neonatal tetanus cases reported in the health information system and perform subprovincial analysis of tetanus toxoid coverage following completion of all three immunization rounds. Efforts also should be made to strengthen clean delivery practices to help eliminate maternal and neonatal tetanus in Papua New Guinea.

Abstract
Between October 1998 and September 2000, 111 consecutive pregnant patients admitted to the Port Moresby General Hospital antenatal ward with a haemoglobin level of 6 g/dl or less were studied. The main causes of the severe anaemia were as follows: iron deficiency on its own or in combination with another factor 66%--iron deficiency on its own 43% and combined folate and iron deficiency 23%--and folate deficiency 18%. Malaria was a contributory factor in 13 patients (12%). A combination of blood film, bone marrow study, serum assays of ferritin, folate and vitamin B12, and mean corpuscular volume (MCV) was used to determine the cause of the anaemia. Ferritin levels on their own poorly correlated with the presence of iron in the bone marrow. A low MCV correlated well with iron deficiency anaemia while a high MCV was associated with folic acid deficiency. It would seem therefore that while a bone marrow study is mandatory to reach a definitive diagnosis of severe anaemia, MCV, in conjunction with the red cell morphology on blood film, would be a good marker for iron and folic acid deficiency anaemia, especially as we do not have serum assays readily available for folate, ferritin and vitamin B12 in Papua New Guinea.

Abstract
From 1 November 1995 to 10 April 1996, 1001 consecutive mothers who had attended the Port Moresby General Hospital (PMGH) antenatal clinic and were delivered in the Maternity Unit of the PMGH were surveyed for their antenatal haemoglobin (Hb) levels. One or more Hb results had been noted in the antenatal records of 997 subjects. The mean of the first Hb level for this sample was 10.6 +/- 1.72 g/dl. The first Hb level was below 10.0 g/dl in 33% of the 997 subjects. The dates were reliable in 777 subjects. The mean first Hb for this group was the same as for the total sample. A subgroup of 449 subjects with reliable dates and first Hb measurement at < or = 26 weeks gestation had a first Hb mean of 10.9 +/- 1.78 g/dl. Among those with reliable dates, 569 had two or more Hb measurements, the last being at > or = 34 weeks. In this subgroup, the mean of the last Hb was 11.1 +/- 1.60 g/dl. The first Hb was measured at < or = 26 weeks in 352 subjects in this subgroup. The means for the first and last Hb levels for this subset were 10.9 +/- 1.78 and 11.1 +/- 1.57 g/dl, respectively; the paired t test did not show any difference between the first and last Hb levels. For subjects in the total sample who had two or more Hb measurements, the mean for the lowest Hb level was 10.0 +/- 1.54; 45% had levels below 10.0 g/dl at some time during the pregnancy.

Abstract
From September 1995 to May 1997, 315 consecutive stillbirths and 315 randomly selected controls were studied at the Port Moresby General Hospital to determine the causes of the deaths, to describe the sociodemographic and reproductive characteristics of the mothers, and to see if there were any avoidable factors in the stillbirths and where the responsibility for them lay. 249 (79%) of the stillbirths were antepartum and 14% were intrapartum; the timing of death could not be determined in the remaining 21 (7%). 36% of the stillbirths were unexplained. The common identified causes were: syphilis (VDRL and TPHA positive) 10%, intrauterine growth restriction/placental insufficiency 9%, antepartum haemorrhage 9%, malaria 6%, major congenital abnormalities 6%, cord accidents 6%, pregnancy-induced hypertension 5% and acute intrapartum asphyxia 4%. Multiple logistic regression analysis showed a significant association between stillbirth and the following variables: husband's occupation unskilled, age over 35 years, poor antenatal attendance, a past history of stillbirth, syphilis and malaria. An avoidable factor was established in 41% of the cases; in 60% the responsibility for the avoidable factor lay with the patient and her relatives.

Abstract
A retrospective study of 274 consecutive primary caesarean sections and 274 unmatched controls was carried out at Port Moresby General Hospital from January to December 1992. The primary caesarean section rate was 3.5%. Stepwise logistic regression analysis showed that primary caesarean section was significantly associated with maternal height of less than 150 cm; nulliparity; symphysis-fundal height of more than 38 cm at admission in labour; cervical dilatation of less than 4 cm at admission in labour; and the level of fetal head at admission in labour of 3/5 or higher.

Abstract
We studied 510 patients in a retrospective, nonrandomized, comparative survey of vaginal births and repeat caesarean section after one primary caesarean section at the Port Moresby General Hospital. 478 (94%) were allowed a trial of scar (TOS). The most common indications for elective caesarean section in the other 32 patients were cephalopelvic disproportion (CPD) 31%, contracted pelvis 19% and preeclampsia 12.5%. In 41% of patients TOS was terminated by emergency caesarean section. Logistic regression analysis showed that the following were significantly associated with repeat caesarean section after TOS: parity of one, no vaginal birth after the primary caesarean section, narrow obstetric conjugate, birthweight of 2500 g or greater, short stature, high level of the head at admission to the labour ward and region of origin.

Abstract
This is a report of ovarian carcinoma occurring in two sisters diagnosed almost at the same time, prompting prophylactic oophorectomy in a third sister. Histology of the overtly normal ovary in the third sister showed a focus of ovarian cancer. Discussion and a review of the literature suggest that any program designed to reduce the incidence of late-stage ovarian carcinoma should include the surveillance of family members of the index case, including the performance of prophylactic oophorectomy in the unaffected members of the family after they have completed their families.

Abstract
Factor V deficiency is a rare hereditary disorder. We report a patient with factor V deficiency who presented with menorrhagia and pelvic haematoma. The Haematology Department at the Royal Brisbane Hospital performed the definitive factor assays leading to the diagnosis. The challenges of her management were obtaining adequate supplies of factor V and her socioeconomic circumstances. The main future challenge will be the supervision of her pregnancies.

Abstract
AIM To identify sociodemographic and obstetric characteristics which could be used as markers for thick meconium staining of the amniotic fluid (MSAF) in labour. METHODS The design was an unmatched case-control study. The setting was the Port Moresby General Hospital labour ward. The eligibility criteria were: patients with a singleton pregnancy, cephalic presentation and baby alive at the time of admission in labour. Cases were parturients who had MSAF during labour. The cases were sequentially enrolled according to the time of delivery recorded in the labour ward register. A control was a patient who did not have MSAF and who was the first to deliver after a case. Data were collected using an interviewer-administered questionnaire and patients' hospital records. RESULTS Logistic regression analysis showed the following variables to have a positive significant association with MSAF: low social status, betelnut chewing, grand multiparity, past history of perinatal death and rupture of membranes to delivery interval. Preterm delivery was negatively associated with MSAF. Compared with the controls, the cases had a higher caesarean section rate; more of their babies were admitted to the Special Care Nursery (SCN); the mean stay of their babies in the SCN was longer; and the perinatal mortality was higher.

PATIENTS A total of 254 consecutive women who attended the family planning clinic at Port Moresby General Hospital, Papua New Guinea were enrolled into this study. METHODS Cervical infections with C trachomatis were diagnosed using the direct immunofluorescent assay (DFA) and the polymerase chain reaction (PCR). Serum IgM and IgG antibodies directed against C trachomatis were detected using the enzyme-linked fluorescent assay (ELFA). RESULTS The prevalence of C trachomatis was 14.6% using the PCR, 9.1% using the DFA and 17.3% when the results of the PCR and the DFA were combined. An elevated IgM titre was observed in 14.2% of the women, whereas 44.1% had an elevated IgG titre. The titres of IgM or IgG were significantly higher in women who were positive using the PCR or the DFA than in those who were negative in both the PCR and the DFA (p = 0.032 and p = 0.0046, respectively). CONCLUSION Cervical infection by C trachomatis can be considered a major health problem in at least the studied population in Papua New Guinea. The prevalence of C trachomatis infection is at least comparable with that in groups with a high prevalence in industrialized countries. Effective screening and treatment programmes are imperative to combat this problem.

Abstract
A clinico-sociodemographic and microbiological survey was carried out at the Port Moresby General Hospital Antenatal Clinic to determine the prevalences of bacterial vaginosis, Trichomonas vaginalis and Candida albicans vaginal infections in pregnancy and to examine if the infections had any association with some suspected sociodemographic risk factors. The study was carried out between December 1990 and January 1991. Of 206 consecutive subjects surveyed, 79 (38%) had symptomatic infection. However, on speculum examination, abnormal discharge was seen in 188 (91%). 118 (57%) had microbiologically confirmed infection. The prevalences of the individual infections were T. vaginalis 19%, C. albicans 23% and bacterial vaginosis 23%. Combined infection, i.e. two infections occurring together in the same subject, was uncommon. None of the infections had an association with any of the sociodemographic characteristics studied. Of the 118 positive subjects, 52 (44%) complained of vaginal discharge and 55 (47%) complained of pruritus.

Abstract
A survey of 673 consecutive Papua New Guinean parturients at the Port Moresby General Hospital, in May and June 1990, showed that 28% had ever used a family planning (FP) method, chiefly a hormonal method (93% of ever-users). Only seventeen of 239 (7.1%) nulliparae had ever used an FP method, compared with 170 of 434 (39.2%) parous subjects. Education of mother and of husband were independently and significantly associated with FP ever-use. Seventeen (4.9%) of 347 women who had a surviving child, had not breast-fed the child. The interval between the birth of the surviving child and the start of the index pregnancy was significantly associated with the duration of breast-feeding; the longer the duration of breast-feeding, the longer the inter birth interval.

Abstract
A survey of 673 consecutive Papua New Guinea parturients carried out at the Port Moresby General Hospital between May and June 1990 showed that socioeconomic and educational factors played a part in predicting perinatal death. Mothers who have previously experienced a perinatal death are more likely to experience a second one.

Abstract
In a survey of 197 consecutive pregnant patients who were attending the Port Moresby General Hospital antenatal clinic for the first time in the index pregnancy, the prevalence of IgG antibodies to Toxoplasma gondii was 18%. Only one patient had IgM antibodies. Of the sociodemographic characteristics examined, only highlands origin of the patient had a significant association with the presence of IgG antibodies.

Abstract
A retrospective survey was carried out of term babies born to Papua New Guinean parents at the Port Moresby General Hospital. Only babies of known gestational age from uncomplicated pregnancies who were delivered after 37 and before 42 completed weeks were included in the study. The purpose of the study was to determine the birthweight distribution at term of uncomplicated pregnancies for Papua New Guineans at the Port Moresby General Hospital. The sources of the data were the patients' case records and the labour ward register. The Epi Info V5 (CDC and WHO) statistical software package was used for the analysis. 404 subjects were studied; 116 of these were nulliparae before the index delivery. For the whole study population some of the findings were as follows: mean birthweight 3251g, standard deviation 403.5, mode 3100g, median 3250g, 10th percentile 2713g, 90th percentile 3750g. Birthweight at 41-42 weeks was significantly greater than at 37-38 completed weeks. The height and parity of the mother and sex of the baby also had significant effects on birthweight but the latest birth interval had no significant influence. Babies of highland mothers were significantly heavier than babies of Papuan mothers.

Abstract
It is well known that antenatal care improves perinatal and maternal outcomes. This is especially true for deprived communities and for the developing world, where women commonly have risk factors. At the Port Moresby General Hospital mothers who did not attend an antenatal clinic in the index pregnancy (unbooked mothers) form about 6% of all mothers delivered. These unbooked mothers have a perinatal death rate which is four times that of those who attended antenatal clinics before their delivery. A case-control survey was conducted of 136 unbooked mothers delivered at the Port Moresby General Hospital and 136 parity-matched control mothers who had been seen antenatally at least three times during their pregnancy. The purpose of the study was to find out if the cases and controls differed in their socioeconomic characteristics and in some selected aspects of their reproductive history. There was no significant difference between the groups in the following: marital status, and distance between present residence and nearest antenatal clinic. The groups were very significantly different in the following characteristics: age less than 20 years, social class, husband's education, and previous antenatal attendance in the penultimate pregnancy. The difference in patient's education was only just significant.

Abstract
The prevalence of endocervical C. trachomatis infection in 181 consecutive antenatal clinic patients at the first attendance and who had not received antibiotic therapy in the previous 4 weeks, was 17.7%. The direct fluorescent antibody test was used for diagnosis. There was no significant clinical or sociodemographic factor which distinguished patients who tested positive from those who tested negative.
