The Clinic of Psychiatry and Medical Psychology (CPPM) of the CHU-Campus of Lomé served as a study setting. The CPPM was opened in 1990 by a ministerial order. It consisted of two hospitalization rooms (male and female) with a capacity of 6 beds each, a nurse’s on-call room, a surveillance office, a store, a staff checkroom and four consultation offices. In addition, there is a room for assistance to drug addicts. The nursing staff of the CPPM was composed of:

­ Two psychiatrists, one of whom is a professor and head of the department;

­ A clinical psychologist;

­ A medical assistant;

­ Two Master’s Degrees in Mental Health;

­ Five state-qualified nurses;

­ Five sick guards.

Type and period of study

This was a retrospective study with a descriptive focus on patients hospitalized at the CPPM of CHU-Campus from January 1st, 2013 to December 31, 2018.

Study population

The study population consisted of patients hospitalized at the CPPM of CHU-Campus during the above-mentioned period. Patients with a medical record of schizoaffective disorder were included in this study.

Inclusion criteria

Patients who were hospitalized at the CPPM of the CHU-Campus during the study period and whose medical file included symptoms and diagnosis of schizoaffective disorder at admission or during the course of the illness were included in this study.

Exclusion criteria

The following were excluded from this study:

­ Patients with schizoaffective disorder whose medical records were incomplete and inoperable.

­ Patients with schizoaffective disorder followed on an outpatient basis.

Data collection technique

The data were collected using a pre-established survey form containing the following parameters: socio-demographic data (age, sex, profession, level of education, marital status), clinical data (history, life events, use of psychoactive substances, symptoms) and treatment methods.

Data analysis technique

These data were entered and processed using Epi Info 7.1.0.6 software. Tables were created using EXCEL 2016 software.

Ethical aspects

The confidentiality of the information’s contained in the patients’ files had been respected.

During our study period, 986 patients were admitted to the CPPM of CHU-Campus. Among them, 46 had a diagnosis of schizoaffective disorder; this represents a hospital prevalence of 4.66%. The average age of the patients was 39.5 years with extremes of 14 and 65 years. The age range of 31 to 40 years was the most represented (32.60%). Females predominated at 52.17%, a sex ratio of 0.92. Married people represented 47.83%. The primary education level represented 34.80%. The unemployed were in the majority at 32.92%. Table 1 summarizes the sociodemographic data.

Sixty-five point twenty two percent (65.22%) of the patients in our study had a personal psychiatric history, either psychotic (58.70%) or mood disorder (6.52%). Family psychiatric history was found in 23.91% of cases. Thirteen point zero four percent (13.04%) of patients had experienced an emotional shock in childhood. The emotional shock was represented by the death of one or both parents in 66.67% of cases. The use of psychoactive substances was found in

23.91% of patients. Alcohol represented 36.37% of the psychoactive substances consumed. All patients had presented delusions. Disorganized speeches, dissociative elements and euphoria each accounted for 95.65% of patients. Hallucination and sadness each accounted for 93.48%. Table 2 summarizes the clinical aspects.

Almost all patients (97.82%) had received a thymoregulator combined with a 1st generation antipsychotic (95.65%). Adverse events were dominated by dyskinesias at 17.40%. The average length of hospital stay was 12 days with extremes of 6 and 60 days. Ninety-three point forty-eight percent (93.48%) of patients had continued medical follow-up after hospitalization and had clinical stabilization. The remaining patients (6.52%) were lost to follow-up. They did not come to the medical check-up anymore. The therapeutic aspects are presented in Table 3.

We recorded 46 patients with schizoaffective disorder, representing a hospital prevalence of 4.66%. The average age of the patients was 39.5 years, with a predominance of the 31 to 40 age group. Thus, this was a young adult population. This involvement of young adults in mental health studies has been demonstrated in the African literature [5] [6] [7] [8]. This result is also similar to that of Mancuso et al. [9] in Australia who found a mean age of 38.32 years. Olfson et al. [10] also found in the USA in a study of the treatment of schizoaffective disorder and schizophrenia, a mean age of 42.5 years.

The female sex was predominant in our study with a frequency of 52.18%. This result is similar to that of Olfson et al. in the USA [10] who found a female predominance of 53.30%. This female predominance has already been described in the south of the Sahara’s literature [5] [6] [11].

In our study, cannabis use in patients with schizoaffective disorder accounted for 18.18%. Bassir Nia et al. in Israel [12], found that schizoaffective disorder was associated with cannabis use in 20.60% of patients in their study of psychiatric comorbidities between the use of synthetic cannabinoids and cannabis.

All patients had presented delusions. The other symptoms found in order of frequency were speech disorganization (95.56%), dissociative elements (95.56%), euphoria (95.56%), hallucinations (93.48%), sadness (93.48%) behaviours disorders (91.30%), irritability (84.79%), insomnia (82.60%), aggressiveness (78.26%), logorrhea (60.90%), incoherent speech (56.52%), bradyphaemia (39.10%), mutism (17.39%) and withdrawal (15.21%). We explain the polymorphism of symptoms by the fact that schizoaffective disorder is an intermediate pathology between schizophrenia and mood disorders.

Almost all patients (97.82%) had received a thymoregulator associated with a 1st generation antipsychotic (95.65%). Hattab et al. in Palestine [13] found that 1st generation of antipsychotics were used in 71.6% of cases, 2nd generation antipsychotics in 44.8% of cases, anticonvulsants in 31% of cases and antidepressants in 31.9% of cases. In our environment, the 1st generation of antipsychotics are the most accessible in terms of treatment cost. Lindenmayer [14] in his review of the literature, found that 2nd generation of antipsychotics had proven their effectiveness in the management of the psychotic and affective components of this disorder.

Our study concerned only patients suffering from schizoaffective disorder and hospitalized in a single psychiatric care facility in Togo. It cannot therefore be generalized to the whole country. Nevertheless, the strengths of our study lie in the rather long study period (5 years) which allows us to have an idea of the hospital frequency of this disorder. It is the first study on this disorder in Togo. It allowed us to determine the profile of patients suffering from schizoaffective disorder in Lomé and to identify the treatment proposed by caregivers in this context.
