Neurological soft signs in first episode psychosis among psychiatric hospital patients and its relationship with dimensions of psychopathology: A comparative study.

Background: Neurological soft signs (NSS), as subtle, nonlocalising neurological abnormalities, are considered as the potential markers of psychosis. However, comparative studies of antipsychotic-naïve patients with first-episode psychosis (FEP) and first degree relatives (FDRs) are uncommon. We compared the prevalence and pattern of NSS in FEPs, their healthy FDRs and a healthy non-relatives' control group (HC), highlighted the relationship between NSS and psychopathology and proposed cut-off scores for prevalence studies. Materials and Methods: Two hundred and two participants per group were recruited. The FEPs were consecutive attendees; FDRs were accompanying caregivers; while the HC were from hospital staff. The Brief Psychiatric Rating Scale and the Neurological Evaluation Scale were used to assess psychopathology dimensions and NSS, respectively. Results: Using an item score of two ('substantial impairment'), the prevalence of at least one NSS was: 91.5% (95% confidence interval [CI]: 86.7%-94.9%), 16.8% (95% CI: 11.8%-22.7%) and 6.5% (95% CI: 3.5%-10.9%), respectively, for FEP, FDRs and HC. FEPs were impaired in a broad range of signs. The noteworthy relationships were as follows: (i) a significant correlation between the negative symptoms' dimension versus number of NSS (r = 0.4), and NSS total score (r = 0.3), (ii) the anxiety/depression dimension correlated negatively with number of NSS (r = -0.3) and (iii) NSS cut across psychosis categories. We propose a cut-off score of ≥ 4 for the number of signs signifying probable impairment. Conclusion: The findings indicate that, subject to further studies, NSS could be regarded as a broader phenotype of neurologic dysfunction associated with psychosis proness.

Association of family history of schizophrenia and history of obstetric complications at birth: relationship with age at onset and psychopathology dimensions in a Nigerian cohort.

BACKGROUND: The nature of the association between obstetric complications (OCs) at birth and the genetic aetiology of schizophrenia remains unclear, as some authors suggest that it is an independent risk factor while others support either interactionism or an epiphenomenon perspective. OBJECTIVE: To examine the association of family history of schizophrenia (FHS) with history of OCs, with a view to assessing whether this relationship moderates clinical phenotypes such as symptom dimensions and age at onset of illness. METHODS: This study examined OCs among schizophrenia probands using the Obstetric Complications Scale. An inquiry into family history was performed using the Family history method. Psychopathological symptom dimensions were assessed using standard scales. Data were analyzed to examine the interaction of FHS and history of OCs with age at onset and symptom dimensions, using ANCOVA. RESULTS: FHS was significantly associated with the disorganized symptoms dimension (p=0.03). History of OCs was significantly associated with earlier age at onset (p=0.007). However, in ANCOVA, the effect of the interaction between FHS and history of OCs was not significant for age at onset and symptom dimensions (P = 0.059). CONCLUSION: FHS was significantly associated with disorganization syndrome, and OCs was significantly associated with age at onset.

Using data from schizophrenia outcome study to estimate the time to treatment outcome and the early-response cut-off score that predicts outcome at week 16

Abstract Background Being able to make an estimation of the time to clinical outcome, and making predictions early during treatment about the possibility of later response/non-response to treatment, is an important asset that can help to guide treatment strategies and counsel patients and caregivers about treatment expectations. Objectives The study aimed to determine the time course to treatment outcome and the psychopathological cut-off score at week 4 that predicts outcome at week 16. Methods This was a naturalistic follow-up study of 160 incident cases of schizophrenia over 16 weeks. Four intervals of follow-up clinical assessments were done. Standard criteria for response and remission were applied. Results The mean (median) times, in weeks, to response and remission using Brief Psychiatric Rating Scale (BPRS) data were 8.1(8.0); 8.4(8.0); and 10.9 (12.0), respectively. The Areas Under the Curves were high, for response (0.909; 95% C.I., 0.85-0.97) and remission (0.86; 95% C.I., 0.81 -0.94) at week 16. A cut-off score of 20.7% reduction in the total BPRS score at week 4, predicted response status (79.5% sensitivity, 84.2% specificity) and remission status (77.6% sensitivity, 73.3% specificity) at week 16. In addition, a cut-off of 10.21% reduction in the total Scale for Assessment of Negative Symptoms (SANS) score at week 4, predicted response (70.8% sensitivity, 95.5% specificity) at week 16. Discussion The results are in line with the general clinical impression that, by 2 months, most acutely ill inpatients are fit for discharge; and introduced for further investigation 10.21% reduction in SANS Score as a marker of treatment resistance in schizophrenia.

Naturalistic clinical and psychosocial outcome of incident cases of schizophrenia in Enugu Federal Psychiatric Hospital: A preliminary report at 4-month follow-up.

INTRODUCTION: Longitudinal outcome studies based on incident and predominantly neuroleptic-naïve cases of schizophrenia are uncommon in the modern literature. AIMS: To determine the proportion of persons with schizophrenia with different levels of clinical and functional outcome at monthly intervals of naturalistic treatment follow-up for 4 months: response, remission and recovery; and to examine the predictors of outcome. SUBJECTS AND METHODS: Consecutive incident cases that fulfilled stringent criteria for schizophrenia were recruited into the study. After a baseline assessment, 160 incident cases of schizophrenia were followed up 4-weekly for indicators of symptomatic and functional outcome for 16 weeks. Standard rating scales were used to assess clinical and functional outcome. Sociodemographic and clinical variables were evaluated as predictors of outcome using multiple regression analysis. RESULTS: The attrition rate at week 16 was 29.4%; hence, 113 subjects (out of 160) were available for assessment at the end of follow-up. Of the 113, 66.4%, by Brief Psychiatric Rating Scale (BPRS), met criteria for response (i.e., >50% reduction), while 20.3% could be judged to be clinically non-responsive to treatment (i.e., <20% decrease). Also, 60.2%, by BPRS, met the criteria for remission, while 44.5% met the criteria for recovery. The most important predictor, at week 16, of clinical and psychosocial outcome was social support (48.7%-51.8% of variance). CONCLUSION: Although as a preliminary report, the present findings are hypothesis-generating, the implication of the results is that, as a group, over a 4-month period of modern hospital treatment, schizophrenia patients who were incident cases progressively experienced significant reduction in psychopathology. The findings, therefore, support earlier international cross-cultural reports of relatively good clinical outcome from developing countries, thereby encouraging the idea of treatment optimism in schizophrenia in Africa.

Mental and physical comorbidity in an Arab primary health care setting.

BACKGROUND: There are no published studies on the comorbidity of common mental conditions (anxiety, depression, and somatization) and physical illnesses in the Arab world. Our aim was to estimate the prevalence of common mental conditions comorbid with physical illnesses among primary care attenders in Kuwait, and the sociodemographic characteristics associated with this comorbidity. METHODS: The Patient Health Questionnaires for somatization, anxiety and depression (PHQ-SAD) were administered to a representative sample of 1046 attenders (M: F = 429: 617; mean age 37.6, SD 12.7) seen in primary care clinics in Kuwait. Based on well-established cut-off scores, the presence and severity of three mental conditions -depression, anxiety, and somatization-was ascertained; physical diagnoses were ascertained by the attending physicians. RESULTS: Of 1046 respondents, 442 (42.3%) had at least one mental condition and 670 (64.1%) had a physical illness diagnosis, viz.: diabetes mellitus (248/670 = 37.0%), hypertension (229/670 = 34.2%), asthma (82/670 = 12.2%), non-chronic physical illnesses (63/670 = 9.4%), or heart disease (48/670 = 7.2%), with 34.4% (360/1046) having mental-physical comorbidity. Male: female ratio for the 670 subjects was 287: 383. The unadjusted odds ratio (OR) for having a mental condition in those with a physical illness vs. those without a physical illness was 4.16 (95% C.I. = 3.12, 5.55). Comorbidity was associated with older age, being divorced or widowed, a lower level of education, and poorer living conditions. Regardless of the physical illness, the most frequent comorbid mental disorder was somatization. The prevalence and severity of mental conditions were associated with the number of physical illnesses. CONCLUSION: As has been reported in other parts of the world, somatization, anxiety, and depression are highly prevalent among primary care attenders in Kuwait and they are typically comorbid with physical illness. Strategies for their prevention and treatment need to take into consideration their association with physical illness and social disadvantage.

Familial aggregation of mood disorders among relatives of schizophrenia probands admitted in a hospital in South-Eastern Nigeria: A family comparative study.

INTRODUCTION: The debate on the current nosological status of schizophrenia and mood disorders as distinct entities is very active among scholars. There is a paucity of genetic epidemiological data to contribute an African perspective to this debate. AIM: This study aimed to assess the morbid risk of mood disorders in the relatives of schizophrenia probands, in comparison with the families of a sample of healthy controls. SUBJECTS AND METHODS: This study elicited the information on the morbid risk of mood disorders among 5259 relatives of schizophrenia probands (n = 138) and 6734 relatives of healthy controls (n = 138) through direct interview of patients, available relatives of patients and the comparison group. The family history approach using the Family Interview for Genetic Studies was utilised to obtain information on the morbid risk of all relatives that could be recalled. The diagnosis of available relatives was confirmed using the Diagnostic Interview for Genetic Studies. Morbid risk estimates were calculated using the Weinberg shorter method for age correction. RESULTS: Morbid risk for mood disorders in the first-, second- and third-degree relatives of schizophrenia probands were 1.39% (95% confidence interval [CI] = 1.23-1.55), 0.86% (95% CI = 0.80-0.92) and 0.55% (95% CI = 0.53-0.57), respectively, compared with 0.45% (95% CI = 0.39-0.51), 0.11% (95% CI = 0.07-0.51) and 0.08% (95% CI = 0.06-0.09), respectively, for the healthy comparison group. CONCLUSION: This result supports the impression that familial risk for mood disorders is significantly higher among relatives of schizophrenia patients, compared with healthy controls and that there could be familial relationship between the predisposition to schizophrenia and mood disorders.
