Item Effect of collaborative care between traditional and faith healers and primary health-care workers on psychosis outcomes in Nigeria and Ghana (COSIMPO): a cluster randomised controlled trial(Elsevier Ltd, 2020) Gureje, O.; Appiah-Poku, J.; Bello, T.; Kola, L.; Araya, R.; Chisholm, D.; Esan, O.B.; Harris, B.; Makanjuola, V.; Othieno, C.; Price, L.Background: Traditional and faith healers (TFH) provide care to a large number of people with psychosis in many sub Saharan African countries but they practise outside the formal mental health system. We aimed to assess the effectiveness and cost-effectiveness of a collaborative shared care model for psychosis delivered by TFH and primary health-care providers (PHCW). Methods: In this cluster-randomised trial in Kumasi, Ghana and Ibadan, Nigeria, we randomly allocated clusters (a primary care clinic and neighbouring TFH facilities) 1:1, stratified by size and country, to an intervention group or enhanced care as usual. The intervention included a manualised collaborative shared care delivered by trained TFH and PHCW. Eligible participants were adults (aged ≥18 years) newly admitted to TFH facilities with active psychotic symptoms (positive and negative syndrome scale [PANSS] score ≥60). The primary outcome, by masked assessments at 6 months, was the difference in psychotic symptom improvement as measured with the PANSS in patients in follow-up at 3 and 6 months. Patients exposure to harmful treatment practices, such as shackling, were also assessed at 3 and 6 months. Care costs were assessed at baseline, 3-month and 6-month follow-up, and for the entire 6 months of follow-up. This trial was registered with the National Institutes of Health Clinical Trial registry, NCT02895269. Findings: Between Sept 1, 2016, and May 3, 2017, 51 clusters were randomly allocated (26 intervention, 25 control) with 307 patients enrolled (166 [54%] in the intervention group and 141 [46%] in the control group). 190 (62%) of participants were men. Baseline mean PANSS score was 107∙3 (SD 17∙5) for the intervention group and 108∙9 (18∙3) for the control group. 286 (93%) completed the 6-month follow-up at which the mean total PANSS score for intervention group was 53∙4 (19∙9) compared with 67∙6 (23∙3) for the control group (adjusted mean difference –15∙01 (95% CI –21∙17 to –8∙84; 0·0001). Harmful practices decreased from 94 (57%) of 166 patients at baseline to 13 (9%) of 152 at 6 months in the intervention group (–0∙48 [–0∙60 to –0∙37] (p<0.001) and from 59 (42%) of 141 patients to 13 (10%) of 134 in the control group (–0·33 [–0∙45 to –0∙21] (p<0.001) with no significant difference between the two groups. Greater reductions in overall care costs were seen in the intervention group than in the control group. At the 6-month assessment, greater reductions in total health service and time costs were seen in the intervention group; however, cumulative costs over this period were higher (US $627 per patient vs $526 in the control group). Five patients in the intervention group had mild extrapyramidal side effects. Interpretation: A collaborative shared care delivered by TFH and conventional health-care providers for people with psychosis was effective and cost-effective. The model of care offers the prospect of scaling up improved care to this vulnerable population in settings with low resourcesItem Spontaneous and emergent extrapyramidal syndromes in Black Africans with first-episode schizophrenia and first exposure to antipsychotics(Taylor & Francis, 2021) Ojagbemi, A.; Chiliza, B.; Bello, T.; Esan, O. B.; Asmal, L.; Emsley, R.; Gureje, O.Background: Persons of African ancestry are thought to carry a higher risk for extrapyramidal syndromes (EPS) in schizophrenia. Aim: We investigated the phenomenon of spontaneous and treatment-emergent EPS in a sample comprising Xhosa (South Africa) and Yoruba (Nigeria) Africans with first-episode schizophrenia and first exposure to antipsychotics. Methods: The Extrapyramidal Symptom Rating Scale (ESRS) and a variety of validated tools were used for the assessment of participants before, and two-weekly after treatment with low dose flupenthixol decanoate. Participants were followed up for 12 months. Association of EPS with clinical characteristics was investigated using Pearson’s correlation and linear regression analyses. Results: Of 88 participants at baseline, 16 (18.1%) had at least one definite EPS prior to antipsychotic exposure and 34 (38.6%) had treatment-emergent EPS. While spontaneous Parkinsonism was associated with negative symptoms (r¼0.2, p¼0.043; b¼0.6, p¼0.043), treatment-emergent EPS demonstrated non-significant correlations with clinical characteristics. Apart from dyskinesia, the frequency of treatment-emergent EPS decreased over 12 months observation. Conclusion: These findings support the hypothesis suggesting that spontaneously occurring Parkinsonism in schizophrenia may be the motor spectrum of negative symptomatology. Future studies of this relationship may lead to early identification of patients who may be more sensitive to EPS.Item The expression of neurological soft signs in two African populations with first-episode schizophrenia(SAGE Publications, 2018) Ojagbemi, A.; Chiliza, B.; Bello, T.; Asmal, L.; Esan, O.B.; Emsley, R.; Gureje, O.Information about patterns of expression of neurological soft signs (NSS) in schizophrenia among individuals belonging to the same genetic ancestry may provide new insight for the understanding of the disease’s genetic functions. This study aimed to investigate whether patterns of NSS expression in first episode schizophrenia are com parable in populations with dissimilar genetic ancestry. A sample of 207 patients with first episode schizophrenia were examined using the Neurological Evaluation Scale before they were exposed to anti-psychotics. They were allocated to two African ancestry groups: Black (81 Yoruba Nigerians, and 18 Xhosa South Africans), and non-Black (98 Colored, and 10 White South Africans). Assessments were carried out using validated measures of clinical characteristics of schizophrenia. We determined the frequency, severity, factor structure, and association of NSS with clinical characteristics. Factor derived categories were compared using the Pearson’s (r) and Tucker’s congruence methods. The associations between factor derived categories and clinical characteristics of schizophrenia were determined using Pearson’s correlations and multiple regression analyses. Neurological soft signs were more frequent and more severe in the Black African ancestry group. Also, the factor structure and presentation of NSS in the two ancestry groups were significantly different. Neurological soft signs, especially motor sequencing and cognitive-perceptual abnormalities, were independently associated with disorganization psychopathologies in all the participant groups. Differences in the profile of NSS in Black compared with non-Black African ancestry patients with first episode schizophrenia may suggest differing patterns of expression of NSS in schizophrenia according to genetic ancestry.Item Neurological Soft Signs, Spontaneous and Treatment Emergent Extrapyramidal Syndromes in Black Africans With First Episode Schizophrenia(Frontiers Media S.A., 2018) Ojagbemi, A.; Chiliza, B.; Bello, T.; Asmal, L.; Esan, O.B.; Emsley, R.; Gureje, O.Background: Very little is known about the relationship between spontaneous and treatment-induced motor syndromes in Africans with first episode schizophrenia. Objective: We investigated the association between spontaneous NSS and EPS, with treatment-induced EPS in a homogenous sample of Black Africans with first episode schizophrenia. Methods: We examined Xhosa (South Africa) and Yoruba (Nigeria) patients, using the Neurological Evaluation Scale and extrapyramidal symptoms scale before and at 3 months after exposure to low dose flupenthixol decanoate. Pearson’s correlations and Linear regression models, controlling for duration of untreated psychosis (D.U.P) and premorbid adjustments, were used in examining associations. Results: Among 99 participants in the baseline sample, 91 (91.8%) and 20 (20.2%) had at least one definite NSS and EPS, respectively, before exposure to antipsychotics. Treatment-induced EPS were recorded in 34 (38.6%). Spontaneous EPS was associated with treatment-emergent Akathisia in participants with a longer D.U.P (r = 0.75, β = 0.70, p=0.008). This association was specific for Parkinsonism (r =0.75, β=0.85, p=0.008) and dyskinesia (r = 0.75, β = 1.70, p = 0.008). Conclusion: Similar to previous findings for tardive dyskinesia in studies implementing longer-term follow-up, spontaneous EPS may also predict short-term antipsychotic induced EPS such as akathisia. These results may be important for early identification of patients at risk of treatment-induced Akathisia-linked psychomotor agitation in first episode schizophrenia.
