ABSTRACT
Objective:To explore the efficacy and safety of sofosbuvir-based direct-acting antiviral treatment in children and adolescent patients with chronic hepatitis C (CHC).Methods:A total of 52 children and adolescent patients who admitted to The Third People′s Hospital of Kunming City and The People′s Hospital of Fuyuan County aged from three to 17 years old with CHC from January 2018 to August 2022 were enrolled, and their basic information was collected. Patients were treated with sofosbuvir/velpatasvir (SOF/VEL) or ledipasvir/sofosbuvir (LDV/SOF) with or without ribavirin for 12 weeks. The biochemical and virological indexes were followed up before and after treatment and 12 weeks after withdrawal. The primary endpoint was the sustained virological response (SVR) at week 12 of follow-up after treatment, and the occurrence of adverse events (AE) during treatment. Statistical analysis was used by nonparametric test.Results:A total of 52 patients with CHC including 38 children and 14 adolescents were enrolled. Thirty-one were male and 21 were female. The age was 9(7, 12) years old. Among 52 patients, seven patients were type 1b, 11 were type 2a, three were type 2, five were type 3a, 18 were type 3b, one was type 6a, three were type 6k, four were type 6n and one was type 6v. Twelve (23.1%) patients were vertical transmission, 21(40.4%) patients had horizontal transmission among family members, two (3.8%) patients were blood fluid transmission, and 17(32.7%) were unknown transmission route. Compared with the baseline levels, Total bilirubin, alanine aminotransferase and aspartate aminotransferase were all significantly decreased after 12 weeks of treatment and 12 weeks after withdrawal, and the differences were statistically significant ( F=12.71, 30.23 and 42.52, respectively, all P<0.05). Up to September 30, 2022, 100.0%(52/52) of patients achieved SVR at the end of treatment. For patients who completed follow-up for 12 weeks after treatment, 95.8%(46/48) achieved SVR. Common AEs during treatment were fatigue (11.5%(6/52)), headache (5.8%(3/52)), dizziness (1.9%(1/52)), abdominal pain (3.8%(2/52)), diarrhea (1.9%(1/52)), rash (1.9%(1/52)) and skin pruritus (1.9%(1/52)). No patients discontinued treatment because of AE. Conclusions:Sofosbuvir-based direct-acting antiviral treatment is efficient and well-tolerated in children and adolescent patients with CHC. No patients discontinued treatment due to AE.
ABSTRACT
Objective To study the clinical features of patients with scrub typhus and provide scientific basis for clinical diagnosis and treatment. Methods Clinical data of patients with scrub typhus in the First Affiliated Hospital of Kunming Medical University from January 2016 to December 2016 were collected. Epidemiological data, clinical manifestations, laboratory findings, image examination results, treatment and outcome were retrospectively analyzed. Results The clinical manifestations included 59 cases (100.0％) with fever, 44 cases (74.6％) with headache, 39 cases (66.1％) with chills, 34 cases (57.6％) with muscle and joint pain, 29 cases (49.2％) with prostration, 49 cases (83.1％) with eschar or ulcer, 42 cases (71.2％) with lymphadenectasis, 23 cases (39.0％) with hepatosplenomegaly. Laboratory test results: 51 cases (86.4％) had normal or elevated white blood cell count, 50 cases of eosinophil reduced (84.7％), 27 cases of blood platelet (PLT) reduced (45.8％), 33 cases of albumin reduced (55.9％), 50 cases of alanine aminotransferase (ALT) increased (84.7％), 48 cases of aspartate aminotransferase (AST) increased (81.4％), and 56.1％ (23/41) of the patients with triiodothyronine (T3), thyroxine (T4), free triiodothyronine (FT3) and free thyroxine (FT4) levels significantly lowered, with predominantly free FT3 reduction (82.6％,19/23); C reactive protein (CRP), procalcitonin (PCT), erythrocyte sedimentation rate (ESR) and ferritin were increased in 93.9％(46/49), 35.4％ (17/48), 64.9％ (24/37), and 83.8％ (31/37) of the patients, and 95.6％(43/45) was accompanied with chest radiographic abnormalities. Tetracycline, doxycycline and azithromycin treatment were all effective. Conclusions The clinical manifestations of patients with scrub typhus, involving multisystem, are diverse and thyroid hormones decrease is observed. Early diagnosis and treatment is the key to improve the prognosis of patients with scrub typhus.
