This trial compared the rate and time of viral clearance in subjects receiving a combination of nitazoxanide, ribavirin, and ivermectin plus Zinc versus those receiving supportive treatment. This non-randomized controlled trial included 62 patients on the triple combination treatment versus 51 age-and sex-matched patients on routine supportive treatment. all of them confirmed cases by positive reverse-transcription polymerase chain reaction of a nasopharyngeal swab. Trial results showed that the clearance rates were 0% and 58.1% on the 7th day and 13.7% and 73.1% on the 15th day in the supportive treatment and combined antiviral groups, respectively. The cumulative clearance rates on the 15th day are 13.7% and 88.7% in the supportive treatment and combined antiviral groups, respectively. This trial concluded by stating that the combined use of nitazoxanide, ribavirin, and ivermectin plus zinc supplement effectively cleared the SARS-COV2 from the nasopharynx in a shorter time than symptomatic therapy.

The rate of liver fibrosis progression in chronic hepatitis C (CHC) patients is highly variable and affected by different factors. This study aimed to assess the role of cirrhosis risk score (CRS) based on 7 genetic variants (7 single-nucleotide polymorphisms [SNPs]) and host factors (age and sex) in the prediction of the rate of fibrosis progression in CHC. Duration of infection was determined in 115 patients. The fibrosis progression rate (FPR) per year was calculated as the ratio between fibrosis stage and the duration of infection. SNP genotyping were performed and CRS was determined based on it. FPR was significantly elevated in patients who acquired infection at age >40 years versus those who acquired infection at 30-40 years and those who acquired infection at <30 years. Median FPR was significantly higher in males than females (0.17 vs. 0.15) with P = 0.001. CRS value ≥0.8 is predictive of patients with high risk for cirrhosis, and CRS value <0.5 is predictive of patients with low risk for cirrhosis. There was significant positive correlation between CRS and FPR (P ≤ 0.001). CRS based on 7 SNPs at cutoff value ≥0.8, age at infection >40 years, and male sex are predictors of higher FPR.

BACKGROUNDDiffusion-weighted magnetic resonance imaging has shown promise in the detection and quantification of hepatic fibrosis. In addition, the liver has numerous endogenous micro-RNAs (miRs) that play important roles in the regulation of biological processes such as cell proliferation and hepatic fibrosis.AIMTo assess diffusion-weighted magnetic resonance imaging and miRs in diagnosing and staging hepatic fibrosis in patients with chronic hepatitis C.METHODSThis prospective study included 208 patients and 82 age- and sex-matched controls who underwent diffusion-weighted magnetic resonance imaging of the abdomen, miR profiling, and liver biopsy. Pathological scoring was classified according to the METAVIR scoring system. The apparent diffusion coefficient (ADC) and miR were calculated and correlated with pathological scoring.RESULTSThe ADC value decreased significantly with the progression of fibrosis, from controls (F0) to patients with early fibrosis (F1 and F2) to those with late fibrosis (F3 and F4) (median 1.92, 1.53, and 1.25 × 10-3 mm2/s, respectively) (P = 0.001). The cut-off ADC value used to differentiate patients from controls was 1.83 × 10-3 mm2/s with an area under the curve (AUC) of 0.992. Combining ADC and miR-200b revealed the highest AUC (0.995) for differentiating patients from controls with an accuracy of 96.9%. The cut-off ADC used to differentiate early fibrosis from late fibrosis was 1.54 × 10-3 mm2/s with an AUC of 0.866. The combination of ADC and miR-200b revealed the best AUC (0.925) for differentiating early fibrosis from late fibrosis with an accuracy of 80.2%. The ADC correlated with miR-200b (r = - 0.61, P = 0.001), miR-21 (r = - 0.62, P = 0.001), and miR-29 (r = 0.52, P = 0.001).CONCLUSIONCombining ADC and miRs offers an alternative surrogate non-invasive diagnostic tool for diagnosing and staging hepatic fibrosis in patients with chronic hepatitis C.
