Abstract Objective To investigate epidemiological factors related to treatment-resistant schizophrenia (TRS) in Northeast Brazil, a region where data about mental health are still scarce. Methods This retrospective cross-sectional study included all patients with schizophrenia currently receiving treatment at the outpatient psychiatric clinic of a tertiary hospital in Northeast Brazil. They were divided into TRS and treatment-responsive groups, and epidemiological characteristics of both groups were compared. A logistic regression model investigated factors related to treatment resistance. Results Two hundred and five patients were included, 155 treatment-resistant and 50 treatment-responsive. The TRS group had higher use of benzodiazepines (36.1 vs. 18%, p = 0.017) and antiepileptics (36.8 vs. 8.0%, p < 0.001), antipsychotic polypharmacy (28.6 vs. 8%, p = 0.003) and suicide attempts (35.6 vs. 20%, p = 0.04). Age at onset was younger (19.7±7.3 vs. 24.6±8.6 years, p = 0.001) and CGI was higher in TRS (3.72±1.00 vs. 3.16±1.00, p = 0.001). In logistic regression, being married was a protector (odds ratio [OR] = 0.248, 95% confidence interval [95%CI] 0.091-0.679, p = 0.007) and younger age at onset was a predictor (OR = 1.076, 95%CI 1.034-1.120, p < 0.001) of treatment resistance. Conclusion Early onset of disease was associated with more treatment resistance, while being married with less resistance. Clinicians should identify early predictors of resistance in order to reduce unfavorable outcomes.

RESUMO INTRODUÇÃO: A mortalidade relacionada ao HIV ainda é alta, especialmente nos países em desenvolvimento. O objetivo deste estudo é investigar os fatores associados ao óbito em pacientes com HIV. MÉTODOS: Trata-se de um estudo transversal com todos os pacientes com HIV admitidos consecutivamente em um hospital terciário de doenças infecciosas em Fortaleza, Nordeste do Brasil, entre janeiro de 2013 e dezembro de 2014. Os pacientes foram divididos em dois grupos: sobreviventes e não sobreviventes. Dados demográficos, clínicos e laboratoriais foram comparados e análise de regressão logística foi feita para investigação dos fatores de risco para óbito. RESULTADOS: Um total de 200 pacientes, com média de idade de 39 anos, foi incluído no estudo, sendo 69,5% do sexo masculino. Óbito ocorreu em 15 pacientes (7,5%). Os não sobreviventes apresentaram maior percentual de homens (93,3 vs. 67,3%, p = 0,037) e um menor tempo de internação (8 ± 6 vs. 18 ± 15 dias, p = 0,005). Na análise multivariada, desorientação (p = 0,035, OR = 5,523), dispneia (p = 0,046, OR = 4,064), LRA (p < 0,001, OR = 18,045), histoplasmose disseminada (p = 0,016, OR = 12,696) e desidrogenase lática (LDH) > 1.000 U/L (p = 0,038, OR = 4,854) foram fatores de risco para óbito. CONCLUSÕES: LRA e histoplasmose disseminada foram os principais fatores de risco para óbito na população estudada. Distúrbios neurológicos e respiratórios, bem como níveis elevados de LDH, também estiveram associados com o aumento da mortalidade em pacientes com HIV.

SUMMARY OBJECTIVE: HIV-related mortality is still high, especially in developed countries. The aim of this study is to investigate factors associated to death in HIV-infected patients. METHODS: This is a cross-sectional study with all HIV adult patients admitted to a tertiary infectious diseases hospital in Fortaleza, Northeast Brazil, from January 2013 to December 2014. Patients were divided into two groups: survivors and non-survivors. Demo-graphical, clinical and laboratory data were compared and a logistic regression was performed in order to investigate risk factors for death. P values ≤0.05 were considered statistically significant. RESULTS: A total of 200 patients with mean age of 39 years were including in the study, 69.5% males. Fifteen patients (7.5%) died. Non-survivors presented a higher percentage of males (93.3 vs. 67.3%, p = 0.037). Non-survivors presented AKI (73.3 vs. 10.3%, p < 0.001), liver dysfunction (33.3 vs. 11.5, p = 0.031), dyspnea (73.3 vs. 33.0%, p = 0.002) and disorientation (33.3 vs. 12.4%, p = 0.025) more frequently. Non-survivors also had higher levels of urea (73.8 ± 52.7vs. 36.1 ± 29.1 mg/dL, p < 0.001), creatinine (1.98 ± 1.65 vs. 1.05 ± 1.07 mg/dL, p < 0.001), aspartate aminotransferase (130.8 vs. 84.8 U/L, p = 0.03), alanine aminotransferase (115.6 vs. 85.4 U/L, p = 0.045) and lactate dehydrogenase (LDH) (1208 vs. 608 U/L, p = 0.012), as well as lower levels of bicarbonate (18.0 ± 4.7 vs. 21.6 ± 4.6 mEq/L, p = 0.016) and PCO2 (27.8 ± 7.7 vs. 33.0 ± 9.3 mmHg, p = 0.05). In multivariate analysis, disorientation (p = 0.035, OR = 5.523, 95%CI = 1.130 – 26.998), dyspnoea (p = 0.046, OR = 4.064, 95%CI = 1.028 – 16.073), AKI (p < 0.001, OR = 18.045, 95%CI = 4.308 – 75.596) and disseminated histoplasmosis (p = 0.016, OR = 12.696, 95%CI = 1.618 – 99.646) and LDH > 1000 U/L (p = 0.038, OR = 4.854, 95%CI = 1.093 – 21.739) were risk factors for death.]CONCLUSION: AKI and disseminated histoplasmosis (DH) were the main risk factors for death in the studied population. Neurologic and respiratory impairment as well as higher levels of LDH also increased mortality in HIV-infected patients.

Resumo Objetivo: Avaliar dados clínicos e laboratoriais, bem como ocorrência de lesão renal aguda (LRA), em crianças HIV positivas com e sem uso de terapia antirretroviral altamente ativa (TARV) antes da admissão. Métodos: Estudo retrospectivo em pacientes pediátricos HIV positivos (< 16 anos). Foram comparadas as crianças que estavam em uso com aquelas sem uso de TARV prévia à internação. Resultados: Foram incluídos 63 pacientes, com média de 5,3 ± 4,27 anos, 55,6% do sexo feminino. LRA foi encontrada em 33 casos (52,3%). Os pacientes que usavam TARV apresentaram menores níveis de potássio (3,9 ± 0,8 vs. 4,5 ± 0,7 mEq/L, p = 0,019) e bicarbonato (19,1 ± 4,9 vs. 23,5 ± 2,2 mEq/L, p = 0,013), bem como maior taxa de filtração glomerular estimada (102,2 ± 36,7 vs. 77,0 ± 32,8 mL/min/1,73m2, p = 0,011), do que o pacientes sem TARV prévia. Na análise multivariada o uso de TARV prévia à internação foi fator protetor contra LRA (p = 0,036; RC = 0,30; IC de 95% = 0,097-0,926). Conclusão: A LRA é uma complicação comum da infecção pediátrica pelo HIV. O uso de TARV antes da internação foi associado a melhor taxa de filtração glomerular e foi fator de proteção contra LRA, porém desencadeou efeitos colaterais como hipocalemia e acidose metabólica.

Abstract Objective: To assess clinical and laboratory data, and acute kidney injury (AKI) in HIV-infected children using and not using highly active antiretroviral therapy (HAART) prior to admission. Methods: A retrospective study was conducted with HIV-infected pediatric patients (<16 years). Children who were using and not using HAART prior to admission were compared. Results: Sixty-three patients were included. Mean age was 5.3 ± 4.27 years; 55.6% were females. AKI was observed in 33 (52.3%) children. Patients on HAART presented lower levels of potassium (3.9 ± 0.8 vs. 4.5 ± 0.7 mEq/L, p = 0.019) and bicarbonate (19.1 ± 4.9 vs. 23.5 ± 2.2 mEq/L, p = 0.013) and had a higher estimated glomerular filtration rate (102.2 ± 36.7 vs. 77.0 ± 32.8 mL/min/1.73 m2, p = 0.011) than those not on HAART. In the multivariate analysis, the use of HAART prior to the admission was a protective factor for AKI (p = 0.036; OR = 0.30; 95% CI = 0.097-0.926). Conclusion: AKI is a common complication of pediatric HIV infection. Use of HAART prior to the admission preserved glomerular filtration and was a protective factor for AKI, but increased medication side effects, such as hypokalemia and renal metabolic acidosis.

SUMMARY Background: The aim of this study is to describe clinical characteristics, outcomes and risk factors for death among patients with HIV-related acute kidney injury (AKI) admitted to an intensive care unit (ICU). Methods: A retrospective study was conducted with HIV-infected AKI patients admitted to the ICU of an infectious diseases hospital in Fortaleza, Brazil. All the patients with confirmed diagnosis of HIV and AKI admitted from January 2004 to December 2011 were included. A comparison between survivors and non-survivors was performed. Risk factors for death were investigated. Results: Among 256 AKI patients admitted to the ICU in the study period, 73 were identified as HIV-infected, with a predominance of male patients (83.6%), and the mean age was 41.2 ± 10.4 years. Non-survivor patients presented higher APACHE II scores (61.4 ± 19 vs. 38.6 ± 18, p = 0.004), used more vasoconstrictors (70.9 vs. 37.5%, p = 0.02) and needed more mechanical ventilation - MV (81.1 vs. 35.3%, p = 0.001). There were 55 deaths (75.3%), most of them (53.4%) due to septic shock. Independent risk factors for mortality were septic shock (OR = 14.2, 95% CI = 2.0-96.9, p = 0.007) and respiratory insufficiency with need of MV (OR = 27.6, 95% CI = 5.0-153.0, p < 0.001). Conclusion: Non-survivor HIV-infected patients with AKI admitted to the ICU presented higher severity APACHE II scores, more respiratory damage and hemodynamic impairment than survivors. Septic shock and respiratory insufficiency were independently associated to death.
