Abstract:
Objective:To understand the epidemiological and clinical characteristics of melioidosis in Haikou City, to rise the people's awareness of melioidosis and to provide basis for prevention and control of the disease.Methods:The clinical data of 254 patients with melioidosis treated in 4 Class A tertiary hospitals in Haikou City from January 2000 to September 2020 were collected, and the epidemiological characteristics, clinical manifestations, infection site, prognosis and drug sensitivity were retrospectively analyzed.Results:Among 254 patients with melioidosis, 226 males (88.98%) and 28 females (11.02%), and the gender ratio was 8.07 ∶ 1.00. Farmers were the main occupation, accounting for 37.80% (96/254). The median age was 53 years old, mainly in 41 - 80 years old, accounting for 83.46% (212/254). Han nationality was the most, accounting for 89.76% (228/254). The onset season was mainly in summer and autumn, and the peak was from August to October (117 cases). Patients were mainly distributed in coastal areas, among which Haikou City (49 cases) was the most, followed by Dongfang City (46 cases), Danzhou City (23 cases) and Wenchang City (21 cases). Totally 196 cases (77.17%) had basic diseases, diabetes was the most common (162 cases). The main symptoms of admission were fever (211 cases), followed by cough (108 cases) and expectoration (88 cases). The infection sites were mainly blood (104 cases, 40.94%), lung (60 cases, 23.62%), liver and spleen (32 cases, 12.60%). Totally 195 patients were treated with sensitive antibiotics, at discharge, 37 cases (18.97%) were cured, 129 cases (66.15%) improved, 18 cases (9.23%) did not heal, 7 cases (3.59%) died and 4 cases (2.05%) were discharged voluntarily. Results of drug sensitivity tests from 2010 to 2020 showed that the sensitivity rates of Burkholderia pseudomallei to imipenem (142 cases), meropenem (16 cases) and ceftazidime (141 cases) were all 100.00%, and the sensitivity rates of doxycycline (25 cases) and compound sulfamethoxazole (142 cases) were 92.00% (23/25) and 99.30% (141/142), respectively. Conclusions:Males, farmers, middle-aged and elderly people and people with diabetes and other basic diseases are the high incidence population of melioidosis in Haikou City. The incidence peak is in summer and autumn. The common clinical manifestations are fever, pulmonary infection, abscess of liver and spleen, etc. In the treatment, Burkholderia pseudomallei is more sensitive to imipenem, meropenem and ceftazidime.
