USTEKINUMAB IN CROHN'S DISEASE MANAGEMENT: A BRAZILIAN OBSERVATIONAL STUDY

BACKGROUND

Real-world data on the use of Ustekinumab (UST) in Brazilian and Latin American patients with Crohn's disease (CD) are scarce.

OBJECTIVE

The primary endpoint was assessment of clinical remission at weeks 8 and 52, and secondary endpoints were: assessment of clinical response at weeks 8 and 52, endoscopic remission, adverse events, and rates of CD-related abdominal surgery during follow-up.

METHODS

observational and retrospective study, including patients with CD treated at two centers, who received UST at any time during their treatment. Remission and clinical response were defined as a Harvey-Bradshaw index ≤4 and ≥3 points reduction, respectively.

RESULTS

Seventy-four patients were included, 85.1% previously exposed to anti-TNFs. Clinical remission was observed in 45.8% and 59.4% of patients at weeks 8 and 52, respectively. The clinical response rates were 54.2% and 67.6% at weeks 8 and 52. Endoscopic remission was observed in 21.8% of patients. Seventeen patients had adverse events, mostly mild infections, with 22.9% of patients undergoing abdominal surgery (ileocolectomy being the most common procedure).

CONCLUSION

UST therapy resulted in significant rates of remission and clinical response, as described in other real-world studies. Few patients had adverse events during treatment, showing its adequate safety profile.

EVALUATION OF PROGRESSION OF HEPATIC FIBROSIS IN A GROUP OF PATIENTS WITH NON-ALCOHOLIC FATTY LIVER DISEASE ACCOMPANIED FOR 10 YEARS

BACKGROUND

Non-alcoholic fatty liver disease has been progressively diagnosed in the general population as a consequence of the increased prevalence of obesity and type 2 diabetes mellitus, its main risk factors. It is characterized by accumulation of fat in the hepatocytes associated with lobular inflammation and balonization, which can lead to cirrhosis and hepatocarcinoma. Thus, a characterization and follow-up of a progression of the fibrosis level of these patients becomes important, being that the transient hepatic elastography is a reliable method for this evaluation with a measure of the kapa index.

OBJECTIVE

To evaluate the progression of hepatic fibrosis through elastography in patients with non-alcoholic fatty liver disease.

METHODS

Patients who had previously performed hepatic biopsy and noninvasive scores for non-alcoholic steatohepatitis (NASH) and fibrosis were included in the study. These same subjects were then submitted to current clinical evaluation, laboratory and liver elastography tests, defining the level of liver fibrosis, about 10 years after the first evaluation.

RESULTS

Data were analyzed for 66 patients previously submitted to liver biopsy. Of these, 16 were not found, four could not participate because they were debilitated due to hepatic cirrhosis, two had died from an automobile accident and five from complications of cirrhosis of the liver. Therefore, of the 50 patients with a known history, 9 (18%) had died of cirrhosis or were unable to attend the examination because of their liver disease. The remaining population was predominantly female (61.5%), mean age of 63 years, being overweight, dyslipidemia (76.9%), disorders of the glycemic profile (76.9%), and metabolic syndrome (82.1%). Of the 39 cases evaluated, 35% had the same degree of fibrosis at the initial evaluation (biopsy) and at the current evaluation (elastography), 33% had an increase in the degree of fibrosis and another 30% had a decrease in the degree of fibrosis. Twenty-eight patients had NASH at baseline. Regarding these patients, it was observed in the current evaluation, that 25% remained stable in the degree of fibrosis, 39% progressed, and 35% regressed.

CONCLUSION

Despite some limitations of our study, such as the small number of patients, and the use of two different methods of evaluation (biopsy and elastography), the data obtained allow us to conclude that of the 39 evaluated cases, 33% (13) presented progression of fibrosis and the total group of 50 patients, 42% had cirrhosis or died due to liver disease. The presence of NASH on hepatic biopsy did not prove to be, in our study, a predictive of the evolution of hepatic fibrosis in the patients.
