Children hepatitis

The reported risk factors for HIV-associated sensory neuropathy are varied and may have changed since the availability of HAART. In the pre-HAART era, age, nutritional deficiencies, alcohol exposure, higher HIV viral load, and low CD4 counts (Moyle and Sadler 1998 Childs et al. 1999), as well as mood, other neurologic disorders and functional abnormalities (Schifitto et al. 2002) were neuropathy risk factors. In the HAART era, the use of NRTI (Cherry et al. 2006 Pettersen et al. 2006) and exposure to protease inhibitor (PI) medication (Pettersen et al. 2006 Smyth et al. 2007) are considered additional risk factors. Although hepatitis C mono-infection has been associated with peripheral nerve disease, and there is...

Hepatic metabolism of ethanol involves a nonlinear saturable pathway. Young children have a limited ability to metabolize and thereby detoxify ethanol. Ethanol intoxication has been recorded in children with blood levels as low as 25 mg/dL. Alcohol has a volume of distribution of approximately 0.65 L/kg. Ingestion of 20 mL of a 10% alcohol solution will produce a blood level of 25 mg/dL in a 30 pound child. The American Academy of Pediatrics (AAP) Committee on Drugs recommends that pharmaceutical formulations intended for use in children should not produce ethanol blood levels of >25 mg/dL after a single dose. 

Urea cycle defects Failure to convert ammonia to urea via urea cycle (Fig. 40-5). Coma, convulsions, vomiting, respiratoryfailure in neonate. Often mistaken for sepsis of the newborn. Mental retardation, failure to thrive, lethargy, ataxia and coma in the older child. Associated with hyperammonemia and abnormalities of blood aminogram Low protein diet Acylation therapy (sodium benzoate, sodium phenylacetate) Arginine therapy in selected syndromes Hepatic transplantation... 

Population PK screening in Phase II and Phase III is useful in assessing the impact of altered hepatic function (as a covariate) in PKs, if those patients are not excluded from Phase II and III trials, and if there is sufficient PK information collected about the patients to characterize them reasonably well. If a population PK approach is used, patients in Phase II and III studies are assessed for encephalopathy, ascites, serum bilirubin, serum albumin, and prothrombin time (which are components of the Child-Pugh score) or a similar group of measures of hepatic function. The population PK study, then, would include the following features ...

Premenopausal use There is no indication for premenopausal use of raloxifene. Hepatic function impairment Raloxifene was studied, as a single dose, in Child-Pugh class A patients with cirrhosis and serum total bilirubin ranging from 0.6 to 2 mg/dL. Plasma raloxifene concentrations were approximately 2.5 times higher than in controls and correlated with total bilirubin concentrations. Safety and efficacy have not been evaluated further in patients with severe hepatic insufficiency. Carcinogenesis In long term carcinogenicity studies in animals there was an increased incidence of ovarian tumors, testicular interstitial cell tumors, and prostatic adenocarcinomas. 

Hepatic function impairment Because iloprost elimination is reduced in patients with impaired liver function, exercise caution during iloprost therapy in patients with at least Child-Pugh class B hepatic impairment. 

Hepatic function impairment- In mild or moderate hepatic impairment (Child-Pugh class A or B), do not exceed 10 mg once daily. In severe hepatic impairment (Child-Pugh class C), the use of tadalafil is not recommended. 

Hepatic function impairment- A starting dose of 5 mg is recommended in patients with moderate hepatic impairment (Child-Pugh B). The maximum dose should not exceed 10 mg. Vardenafil has not been evaluated in patients with severe hepatic impairment (Child-Pugh C). 

Naratriptan and sumatriptan Cerebrovascular or peripheral vascular syndromes, severe hepatic impairment (Child-Pugh grade C) severe renal impairment (Ccr less than 15 mL/min) (naratriptan only). 

Hepatic function impairment For patients with moderate hepatic function impairment (Child-Pugh Class B), reduce initial and target doses to 50% of the normal dose. For patients with severe hepatic function impairment (Child-Pugh Class C), reduce initial and target doses to 25% of normal. 

Hepatic function impairment Atomoxetine exposure (AUC) is increased, compared with normal subjects, in EM subjects with moderate (Child-Pugh Class B) (2-fold increase) and severe (Child-Pugh Class C) (4-fold increase) hepatic insufficiency. Dosage adjustment is recommended for patients with moderate or severe hepatic insufficiency (see Administration and Dosage). 

Hepatic function impairment Reduce initial, escalation, and maintenance doses by approximately 50% in patients with moderate (Child Pugh grade B) and 75% in patients with severe (Child Pugh grade C) hepatic impairment. 

Hepatic function impairment In patients with severe hepatic impairment (Child-Pugh class C), the initial dose of tigecycline should be 100 mg, followed by a reduced maintenance dose of 25 mg every 12 hours. Patients with severe hepatic impairment should be treated with caution and monitored for treatment response. 

It is recommended that the standard loading dose regimens be used but that the maintenance dose be halved in patients with mild to moderate hepatic cirrhosis (Child-Pugh class A and B). 

Evaluate liver function tests at the start of and during the course of voriconazole therapy. Monitor patients who develop abnormal liver function tests during voriconazole therapy for the development of more severe hepatic injury. Discontinuation of voriconazole must be considered if clinical signs and symptoms consistent with liver disease develop that may be attributable to voriconazole. Hepatic function impairment It is recommended that the standard loading dose regimens be used but that the maintenance dose be halved in patients with mild to moderate hepatic cirrhosis (Child-Pugh class A and B) receiving voriconazole. 

Hepatic function Impairment A dosage reduction is recommended for patients with moderate hepatic insufficiency. There is no clinical experience in patients with severe hepatic insufficiency (Child-Pugh score greater than 9). 

Known hypersensitivity to any of the ingredients of the product moderate to severe (Child-Pugh class B and C, respectively) hepatic insufficiency. 

Capsules - Use with caution in patients with moderate or severe hepatic impairment. Patients with Child-Pugh scores ranging from 5 to 8 should receive a reduced dose of amprenavir capsules of 450 mg twice daily, and patients with a Child-Pugh score ranging from 9 to 12 should receive a reduced dose of amprenavir capsules of 300 mg twice daily. 

Dose adjustment in hepatic Impairment The recommended dose of abacavir in patients with mild hepatic impairment (Child-Pugh score 5 to 6) is 200 mg twice daily. To enable dose reduction, use abacavir oral solution (10 ml twice daily) to treat these patients. The safety, efficacy, and pharmacokinetic properties of abacavir have not been established in patients with moderate to severe hepatic impairment therefore, abacavir is contraindicated in these patients. 

Moderate or severe hepatic impairment (Child-Pugh score greater than 6). 

Hepatic function impairment Reduce fosamprenavir dose to 700 mg twice daily, in patients with mild or moderate hepatic impairment (Child-Pugh score ranging from 5 to 8) receiving fosamprenavir without concurrent ritonavir. Do not use fosamprenavir in patients with severe hepatic impairment (Child-Pugh score ranging from 9 to 12).
