ABSTRACT Given the magnitude of COVID-19 and the increase in hospitalization cases for severe acute respiratory syndrome (SARS), especially among patients with diabetes mellitus, it is essential to understand the epidemiological aspects inherent to the disease and the worsening of cases. Thus, this study aimed to analyze the survival of patients with diabetes mellitus hospitalized for SARS due to COVID-19 in different regions of Brazil. This is a longitudinal study, carried out based on data reported in the Influenza Epidemiological Surveillance Information System during the year 2020. The number of patients with diabetes mellitus among the hospitalized cases of SARS due to COVID-19 in the different regions of Brazil and the lethality rate among them were identified. A comparison of patient profiles of those who survived or did not survive and the Cox regression analysis were performed to evaluate the factors associated with shorter survival of patients. It was found that 51.4% of patients hospitalized with SARS due to COVID-19 had diabetes, and the case lethality rate among them was 45.0%. The Northeastern and Northern regions presented a higher proportion of patients with diabetes mellitus (56.5% and 54.3%, respectively) and a higher lethality rate (53.8% and 59.9%, respectively). The mean survival time of cases with diabetes mellitus hospitalized for SARS due to COVID-19 was estimated to be 35.7 days (0.5 days). A lower survival rate was observed among residents of the Northeastern and Northern regions with skin color reported as non-white, who required admission to Intensive Care Units and invasive mechanical ventilation, and presented respiratory symptoms such as dyspnea, respiratory distress and an oxygen saturation lower than 95%. It is concluded that diabetes mellitus was responsible for the high occurrence and lethality, mainly in the Northeastern and Northern regions, among non-white patients and those with greater clinical severity, which reinforces the importance of taking measures aimed at supporting this population.

OBJETIVO: Detectar diferenças nas prevalências das dislipidemias em adultos da demanda laboratorial de três diferentes prestadores de assistência médica, em Salvador, 1995. MÉTODOS: Estudo seccional, clínico epidemiológico, baseado em resultados das dosagens de lípides séricos de uma amostra probabilística de 25% dos 104 laboratórios que usavam o mesmo método de dosagem e o mesmo padrão para controle de qualidade. O critério de dislipidemia foi o do II Consenso Brasileiro de Dislipidemias para adultos. Os resultados foram agrupados conforme procedência: Sistema Único de Saúde (SUS), convênios (C) e seguros privados + particulares (SP). Análise: prevalência com intervalos de confiança (IC) a 95%, e teste do chi². RESULTADOS: Dos 5.464 adultos com menção da procedência, 14,8% foram do SUS, 31,6% dos C e 53,6% dos S+P. As mais elevadas prevalências de hipercolesterolemia - 28,0% (IC 24,0; 32,0) e de LDL-c elevado - 30,4% (IC 27,6; 33,2) foram detectadas no grupo C. No grupo S+P concentraram-se as maiores prevalências de HDL-c anormal - 12,3% (IC 10,0; 13,8) e hipertrigliceridemia - 17,8% (IC 16,3; 19,3). Quase todas as diferenças entre as prevalências foram estatisticamente significantes, favoráveis às taxas mais baixas do SUS. CONCLUSÃO: O melhor perfil lipídico do grupo SUS sugere diferenças sociais nas prevalências das dislipidemias. Para os três prestadores de assistência, a prevalência do HDL-c <35mg/dL foi baixa quando comparada às das demais dislipidemias. Os resultados podem ser inferidos para a prática médica dos respectivos prestadores de assistência e indicam a necessidade de informação e de orientação dos usuários para redução das dislipidemias e melhoria do estilo de vida.

OBJECTIVE: To detect differences in the prevalence of dyslipidemia in adult ambulatory laboratory tests from three different health care providers, in Salvador-Brazil, 1995. METHODS: The study was carried out using a probabilistic sample of 24 out of 104 laboratories (<FONT FACE=Symbol>@</FONT>25%) which performed the same enzymatic method for lipid tests with the same quality control. Laboratory tests results were separated into three groups, according to health care provider: Sistema Único de Saúde (SUS, governamental), Health Maintenance Organizations (HMO), and Private or Patients Health Insurance (PHI). Criteria for dyslipidemias in mg/dL were: total cholesterol > or = 240; LDL-c > or = 160; HDL-c <35 and triglycerides > or = 200. Prevalence rates, 95% confidence intervals (CI) and chi² test were used in the analysis. RESULTS: From the 5464 adult subjects, 14.8% were from SUS, 31.6%. from HMO and 53.6% PHI. The highest prevalence for hypercholesterolemia - 28.0% (CI 24.0; 32.0) and for LDL-c > or = 160mg/dL - 30.4% (CI 27.6; 33.2), were found in the HMO group. PHI had the highest prevalence for HDL-c <35mg/dL - 12.3% (CI 10.0; 13.8), and for hypertrygliceridemia - 17.8% (CI 16.3; 19.3). Most of the differences among health providers were statistically significant. CONCLUSION: The best lypid profile observed in subjects from SUS suggests social differences in the prevalence of dyslipidemias. As compared to other dyslipidemias, HDL-c <35mg/dL prevalence was lower than expected in all three groups. The data may provide insights to medical doctors and other health care professionals regarding the questions of dyslipidemias. It can also provide objective information to the patients and encourage them to change their life styles.

OBJETIVO: Determinar a prevalência das dislipidemias em adultos da demanda laboratorial não-hospitalar da cidade de Salvador (BA). MÉTODOS: Casuística procedente de amostra probabilística de 25% dos laboratórios não-hospitalares da cidade que usavam o método enzimático para dosagem dos lípides séricos e controle de qualidade da Sociedade Brasileira de Patologia Clínica (93% do total); LDL estimado pela fórmula de Friedewald. Sorteados os meses ímpares de 1995 para o estudo. Critérios para dislipidemias, em mg/dl: colesterol <FONT FACE=Symbol>³</FONT>240; LDL <FONT FACE=Symbol>³</FONT>160; HDL <35 e triglicérides <FONT FACE=Symbol>³</FONT>200. Análise: prevalências, seus intervalos de confiança (IC) a 95% e qui-quadrado (chi²). RESULTADOS: Excluídos uma recusa e um laboratório que arquivava laudos só por 3 meses, foram analisados dados de 24 dos 26 laboratórios amostrados. Dos 7392 adultos, 65,5% eram mulheres. Prevalências estimadas e valores dos IC a 95% para homens, foram: hipercolesterolemia =24,0% (20,5; 27,5); LDL elevado =26,1 (22,4; 29,3); HDL baixo =15,9 (14,2; 17,8) e hipertrigliceridemia =27,6 (25,7; 29,5). Para mulheres: hipercolesterolemia =30,0 (27,8; 32,2), LDL elevado =33,1 (30,8; 35,4); HDL baixo =8,0 (7,1; 8,9) e hipertrigliceridemia =30,4 (29,0; 31,4). Todas as prevalências diferiram significantemente inter-gênero (p, 0,05 a p<0,001). Também foram mais freqüentes nas mulheres os níveis indesejáveis do colesterol e LDL. CONCLUSÃO: As dislipidemias são importante fator de risco para aterosclerose na demanda laboratorial de Salvador em ambos os gêneros. Os resultados subsidiam os médicos para incentivar mudanças no estilo de vida que conduzam seus pacientes a níveis lipídicos desejáveis.

PURPOSE: To determine the prevalence of dyslipidemia in non-hospital laboratory tests of adults from Salvador, Brazil. METHODS: The study was carried out in subjects from a probabilistic sample of 25% of a total of 104 local laboratories that used the same enzymatic method for lipid analysis with the quality control as recommended by the Brazilian Society of Clinical Analyses. These represented 93% of all non-hospital laboratories of Salvador in 1995. The odd months of 1995 were selected for sampling in the present study. Criteria for dyslipidemias were: total cholesterol <FONT FACE=Symbol>³</FONT>240; LDL <FONT FACE=Symbol>³</FONT>160; HDL <35 and triglycerides <FONT FACE=Symbol>³</FONT>200mg/dl. Prevalence rates and their 95% confidence intervals (CI) and chi² test were used in the analyses. RESULTS: Tests from two of the 26 laboratories were not used in the analyses due to file problems or refusal. 7,392 adults were screened, 65% female. We observed prevalence (95% CI) of hypercholesterolemia in 30.0 (27.8; 32.2)%, high LDL in 30.1 (30.8; 35.4)% and hypertriglyceridemia in 30.4 (29.0; 31.4)% of the females. As to the male subjects, prevalences were: 24.0 (20.5; 27.5)% for hypercholesterolemia, 26.1 (22.4; 29.3)% for high LDL, 27.6 (25.7; 29.5)% for hypertriglyceridemia. All gender differences were significant. Low HDL occurred in 15.9 (14.2; 17.8)% of males and in 8.0 (7.1; 8.9)% of females. CONCLUSION: Dyslipidemia is an important risk factor observed in non-hospital laboratory tests of men and women in Salvador. Our data may provide physicians and other health care professionals with objective information to encourage life-style changes.
