ABSTRACT
BACKGROUND: Antipsychotic-associated extrapyramidal syndromes (EPS) are a common side effect that may result in discontinuation of treatment. Although some clinical features of individuals who develop specific EPSs are well defined, no specific laboratory parameter has been identified to predict the risk of developing EPS. METHODS: Three hundred and ninety hospitalizations of patients under antipsychotic medication were evaluated. Machine learning techniques were applied to laboratory parameters routinely collected at admission. RESULTS: Random forests classifier gave the most promising results to show the importance of parameters in developing EPS. Albumin has the maximum importance in the model with 4.28% followed by folate with 4.09%. The mean albumin levels of EPS and non-EPS group was 4,06 ± 0,40 and 4,24 ± 0,37 (p = 0,027) and folate level was 6,42 ± 3,44 and 7,95 ± 4,16 (p = 0,05) respectively. Both parameters showed lower levels in EPS group. CONCLUSIONS: Our results suggest that relatively low albumin and folate levels may be associated with developing EPS. Further research is needed to determine cut-off levels for these candidate markers to predict EPS.

ABSTRACT Purpose: This study aimed to investigate the effects of tricyclic antidepressants, selective serotonin reuptake inhibitors, and selective serotonin noradrenaline reuptake inhibitors on the ocular surface. Methods: The study included 330 eyes of 165 patients using antidepressants and 202 eyes of 101 controls. Tear fluid breakup time, Schirmer I test, and Ocular Surface Disease Index (OSDI) questionnaire were administered. Beck Depression Inventory and Beck Anxiety Inventory were applied to record drug use, dosages, psychiatric disease duration, and remission time. Results: Mean tear fluid breakup time was 14.29 ± 4.81 (4-26) sec, and Schirmer I test value was 16.05 ± 5.89 (2-28) mm in study group. Tear fluid breakup time was 18.16 ± 2.12 (15-24) sec and Schirmer I test value was 16.64 ± 2.31 (15-24) mm in control group (p<0.001 and p=0.005, respectively). In study group, 38.18% (n=63) of patients had dry eye, and 17% (n=18) of patients in control group had dry eye (p<0.001). The mean OSDI score was 82.56 ± 16.21 (66-100) in the tricyclic antidepressants Group, 60.02 ± 29.18 (10-100) in the serotonin reuptake inhibitors Group, and 22.30 ± 20.87 (0-75) in the serotonin-noradrenaline reuptake inhibitors Group (p<0.001). Mean tear fluid breakup time was 14.36 ± 3.35 (10-20) sec in tricyclic antidepressants Group, 13.94 ± 5.81 (4-26) sec in the serotonin reuptake inhibitors Group, and 14.93 ± 4.20 (6-20) sec in serotonin-noradrenaline reuptake inhibitors Group (p=0.730). The mean Schirmer I test value was 9.90 ± 7.22 (2-30) mm in tricyclic antidepressants Group, 15.55 ± 5.15 (2-25) mm in serotonin reuptake inhibitors Group and 17.71 ± 4.21 (10-30) mm in serotonin-noradrenaline reuptake inhibitors Group (p<0.001). There was no statistically significant difference between OSDI score, tear fluid breakup time, and Schirmer I test values in serotonin reuptake inhibitors and serotonin-noradrenaline reuptake inhibitors subgroups. Conclusions: Dry eye is common in antidepressant users, but considering the ocular surface, serotonin-noradrenaline reuptake inhibitors may be more reliable than other antidepressants. Patients using serotonin-noradrenaline reuptake inhibitors have lower OSDI scores. Serotonin-noradrenaline reuptake inhibitors, which are useful in chronic pain syndromes, may also have a corrective effect on dry eye symptoms.
RESUMO Objetivo: O objetivo deste estudo é investigar os efeitos dos antidepressivos tricíclicos, dos inibidores da recaptação da serotonina e dos inibidores da recaptação da serotonina e noradrenalina na superfície ocular. Métodos: Foram incluídos no estudo 330 olhos de 165 pacientes em uso de antidepressivos e 202 olhos de 101 controles. Foi medido o tempo de ruptura do fluido lacrimal e foram administrados o teste de Schirmer I e o questionário Ocular Surface Disease Index (OSDI). Os Inventários de Depressão e de Ansiedade de Beck foram aplicados ao uso dos medicamentos e foram registrados as dosagens, a duração da doença psiquiátrica e o tempo de remissão. Resultados: No grupo de estudo, o tempo médio de ruptura do fluido lacrimal foi de 14,29 ± 4,81 segundos (intervalo de 4-26 segundos) e o valor médio do teste de Schirmer I foi de 16,05 ± 5,89 mm (intervalo de 2-28 mm). No grupo controle. o tempo médio de rompimento do fluido lacrimal foi de 18,16 ± 2,12 segundos (intervalo de 15-24 segundos) e o valor do teste de Schirmer I foi de 16,64 ± 2,31 mm (intervalo de 15-24 mm), com p<0,001 e p=0,005, respectivamente. No grupo de estudo, 38,18% (n=63) dos pacientes tinham olho seco, enquanto no grupo controle 17% (n=18) tinham olho seco (p<0,001). O escore médio no OSDI foi de 82,56 ± 16,21 (intervalo 66-100) no grupo dos antidepressivos tricíclicos, 60,02 ± 29,18 (10-100) no grupo dos inibidores da recaptação da serotonina e 22,30 ± 20,87 (0-75) no grupo dos inibidores da recaptação da serotonina e noradrenalina (p<0,001). O tempo médio de rompimento do fluido lacrimal foi de 14,36 ± 3,35 segundos (intervalo de 10-20 segundos) no grupo dos antidepressivos tricíclicos, 13,94 ± 5,81 segundos (intervalo de 4-26 segundos) no grupo dos inibidores da recaptação de serotonina e 14,93 ± 4,20 segundos (intervalo de 6-20 segundos) no grupo dos inibidores da recaptação de serotonina e noradrenalina (p=0,730). O valor médio do teste de Schirmer I foi de 9,90 ± 7,22 mm (intervalo de 2-30 mm) no grupo dos antidepressivos tricíclicos, 15,55 ± 5,15 mm (intervalo de 2-25 mm) no grupo dos inibidores da recaptação da serotonina e 17,71 ± 4,21 mm (intervalo de 10-30 mm) no grupo dos inibidores da recaptação da serotonina e noradrenalina (p<0,001). Não houve diferença estatisticamente significativa no escore OSDI, no tempo de ruptura do fluido lacrimal e nos valores do teste de Schirmer I entre os subgrupos de pacientes em uso de inibidores da recaptação de serotonina e de inibidores da recaptação de serotonina e noradrenalina. Conclusões: Olho seco é uma queixa comum em usuários de antidepressivos, mas no que diz respeito à superfície ocular, inibidores da recaptação de serotonina e noradrenalina podem ser mais confiáveis que outros antidepressivos. Pacientes em uso de inibidores da recaptação de serotonina e noradrenalina têm escores menores no questionário OSDI. Os inibidores da recaptação da serotonina e noradrenalina, úteis nas síndromes de dor crônica, também podem ter um efeito corretivo nos sintomas de olho seco.

There was no statistically significant difference between OSDI score, tear fluid breakup time, and Schirmer I test values in serotonin reuptake inhibitors and serotonin-no-radrenaline reuptake inhibitors subgroups. CONCLUSIONS: Dry eye is common in antidepressant users, but considering the ocular surface, serotonin-noradrenaline reuptake inhibitors may be more reliable than other antidepressants. Patients using serotonin-noradrenaline reuptake inhibitors have lower OSDI scores. Serotonin-noradrenaline reuptake inhibitors, which are useful in chronic pain syndromes, may also have a corrective effect on dry eye symptoms.

Objective: Neuroleptic malignant syndrome (NMS) is a rare but severe side effect of antipsychotic medication. Neutrophil-lymphocyte ratio (NLR) is a simple marker used to measure systemic inflammation. Method : In this case report we explore the relationship of inflammation in the etiology of NMS. In our case involving NMS, although there was no leukocytosis, the NLR was increased up to systemic infection levels. Conclusion: We hypothesized that systemic inflammation may take a role in developing NMS. If so, NLR could be a new marker of NMS that may be able to provide more sensitive results than leukocyte levels.
ABSTRACT
Background: Neuroleptic malignant syndrome (NMS) is a life-threatening side effect of antipsychotic medication. In this study, we aimed to investigate the hypothesis of inflammation via neutrophil-lymphocyte ratio (NLR) in the etiology of NMS. Methods: In this retrospective case-control study, data were collected using digital database of Bakirköy Mental Health Research and Training State Hospital by screening NMS diagnosis according to 'International Classification of Diseases (ICD-10) code: G21.0' between the years of 2007 and 2017. We included 32 hospitalizations with the diagnosis of NMS and 31 other acute psychiatric hospitalizations without NMS of same patients. NLR was calculated as proportion of absolute neutrophil count to absolute lymphocyte count. Significance level was accepted as p < .05. Results: The mean NLR value of NMS group was 9.55 ± 5.13 and control group was 2.06 ± 0.71 (p < .001). According to ROC analysis in our study group, we found a mean NLR cutoff value ≥4 and lymphocyte percent cutoff of ≤18.4% have the probability of correctly identifying patients with NMS with the 100% sensitivity and 100% specificity. Conclusions: In this retrospective study, we considered that higher NLR value in NMS episode might be a resemblance of systemic inflammatory state. In addition, our results suggest that both NLR and lymphocyte percentage may be alternative minor criteria which are more sensitive and specific than leukocyte levels and CPK.

Background: Neuroleptic malignant syndrome (NMS) is a rare but life-threatening side effect. NMS patients usually develop dehydration and fluid-electrolyte imbalance. In this study, we aimed to investigate serum osmolarity and blood viscosity in patients with NMS.Methods: This was a retrospective case-control study including 32 admissions of 27 patients with the diagnosis of NMS. As a control group, 31 non-NMS episodes of hospitalizations of the same patients were included.Results: Serum osmolarity of NMS group was 301.83 ± 20.27 mOsm/L and control group was 294.20 ± 5.92 mOsm/L. Serum osmolarity of NMS group was statistically significantly higher than the controls (p = .018). Whole blood viscosity (WBV) at high shear rate (HSR) value of NMS group was 16.17 ± 1.48 and control group was 16.50 ± 1.38 (p = .331). Regarding WBV at low shear rate (LSR) values, also no statistically significant difference was observed between groups. LSR values of NMS and control group were 39.86 ± 30.11 and 47.41 ± 28.43, respectively (p = .387).Conclusions: Our findings indicate that serum osmolarity of NMS group was statistically significantly higher than the controls. In terms of blood viscosity, there was no statistically significant difference between groups. Higher serum osmolarity in NMS patients than controls may be a reflection of a relative hemoconcentration in NMS.KEY POINTSNMS is usually associated with dehydration resulting in fluid-electrolyte imbalance.We compared the NMS episodes with non-NMS hospitalizations (as control group) of the same patients.Serum osmolarity was statistically significantly higher in NMS group than the controls.There was no statistically significant difference between groups in terms of blood viscosity.
