  1. Breakout session Ryan White Marion Peters August 2020

  2. ARS Question 1: Which statement is true about HCV/HIV 1. Treatment of HIV/ HCV coinfection differs from HCV monoinfection 2. HCV Ab protects against reinfection with HCV 3. Spontaneous clearance is common after acute HCV infection in PLWH 4. HCC occurs after cure of HCV

  3. Case 1 Case 1 63 AA male with HTN, hyperlipidemia and HIV referred for abnormal LFTs Exam and key labs: AST 63 ALT 52 Cr 0.8 PLT 78 ALB 3.4 INR 1.1 Tbili 0.9 Meds: omeprazole 20 mg QD, HCTZ, rosuvastatin 5mg Dolutegravir, TAF and 3TC

  4. Evaluation of Abnormal LFTs in PLWH Evaluation of Abnormal LFTs in PLWH Liver Tests: -Function: Albumin, bilirubin, INR -Cholestasis: Alk Phos, bilirubin Common liver diseases: HBV: HBsAg, anti-HBs, anti-HBc HCV: HCV Ab, HCV RNA NAFLD: Fasting glucose, TG, cholesterol, Hgb A1c Less common Metabolic: Iron, Tsat, ferritin (hemochromatosis), Ceruloplasmin (Wilson Disease) Autoimmune diseases: AMA, IgM (for PBC), ASMA, ANA, IgG (for AIH) A1AT phenotype Hepatotoxicity -Inflammation: AST, ALT -portal HTN: platelets, WBC -alcohol -drug toxicity Fibrosis: APRI: AST/Platelet ratio; FIB-4 (AST, ALT, plt, age); Fibroscan, ARFI (ultrasound) Liver biopsy Imaging only if PHTN Vaccination status for HAV (IgG) and HBV Liver imaging and fibrosis assessment

  5. Fibrosis Assessment Fibrosis Assessment APRI: AST/Platelet ratio; 2.02= cirrhosis FIB-4 (AST, ALT, plt, age); 7.06 = cirrhosis Fibroscan, ARFI (ultrasound) Liver biopsy not needed Imaging only useful to diagnose fibrosis severity if PHTN Ultrasound: nodular liver with splenomegaly HCV RNA 5 million

  6. Case 1 Case 1 63 AA male HTN, hyperlipidemia HIV and HCV GT1a Cirrhosis based on FIB-4 and nodular liver on imaging with splenomegaly HCV RNA 5 million Exam and key labs: Abd: No ascites. No asterixis PLT 78 ALB 3.4 INR 1.1 Tbili 0.9 AST 63 ALT 52 Cr 0.8 (CTP A6) Meds: omeprazole 20 mg QD, HCTZ, rosuvastatin 5mg Dolutegravir, TAF and 3TC

  7. Treatment Treatment- -Naive Genotype 1a with HIV and Naive Genotype 1a with HIV and Compensated Recommended regimens listed by evidence level and alphabetically Compensated Cirrhosis Cirrhosis Daily fixed-dose combination of elbasvir (50 mg)/grazoprevir (100 mg) for patients without baseline NS5A RASsbfor elbasvir 12 weeks I, A Daily fixed-dose combination of ledipasvir (90 mg)/sofosbuvir (400 mg) 12 weeks I, A Daily fixed-dose combination of sofosbuvir (400 mg)/velpatasvir (100 mg) 12 weeks I, A 8 (12) weeks (HIV) Daily fixed-dose combination of glecaprevir (300 mg)/pibrentasvir (120 mg)c I, B bIncludes genotype 1a RASs at amino acid position 28, 30, 31, or 93 known to confer antiviral resistance. If 1 or more RASs are present, another recommended regimen should be used. cDosing is 3 coformulated tablets (glecaprevir [100 mg]/pibrentasvir [40 mg]) taken once daily.

  8. Recommended treatment HCV simplified Recommended treatment HCV simplified without cirrhosis without cirrhosis- - not for HIV HCV coinfected not for HIV HCV coinfected Genotype 1-6: Glecaprevir (300 mg) / pibrentasvir (120 mg) to be taken with food for a duration of 8 weeks Genotype 1, 2, 4, 5, or 6 Sofosbuvir (400 mg) / velpatasvir (100 mg) for a duration of 12 weeks NOTE: Patients with genotype 3 require baseline NS5A resistance- associated substitution (RAS) testing. Those without Y93H can be treated with 12 weeks of sofosbuvir/velpatasvir. If Y93H is present, see HCV guidance for treatment recommendations.

  9. Drug drug interactions Drug drug interactions Omeprazole with SOF/LED (take together on empty stomach) Omeprazole with SOF/VEL (take DAA with food then PPI 4 hours later) Rosuvastatin- do not use with SOF/LED or SOF/VEL/VOX You don t need to remember, you only need to CHECK HCVguidelines.org University of Liverpool: https://www.hep-druginteractions.org/checker

  10. How to follow up How to follow up No liver follow up Follow up for concommitant disease Follow up for cirrhosis

  11. Case 1 HCV Cured but still a liver problem Case 1 HCV Cured but still a liver problem Cirrhotic so needs q6 monthly AFP and imaging Fibroscan 29kPA and CAP 380 So cirrhotic with portal HTN and steatosis Obesity, HTN, HLD, steatosis Hgb A1c 6.5% fasting glucose 125- borderline diabetes Control weight (diet and exercise), diabetes, cholesterol Healthy life style, limit alcohol, THC not daily

  12. ARS Question 2: Which statement is true in NAFLD and PLWH 1. Fatty liver disease is uncommon in PLWH 2. Liver Fibrosis is uncommon in PLWH with NAFLD 3. Fibroscan can measure fat and fibrosis 4. ART does not lead to weight gain

  13. Transient Elastography

  14. Elastography: Fibroscan 2.5 kPa Affected by weight, access of probe (2 cm), steatosis

  15. VCTE: Probe Selection Guidance VCTE: Probe Selection Guidance Skin To Capsule Distance 31 mm XL Probe Selection Tool XL Amplitude TimeMotion

  16. Problems with VCTE (Fibroscan) False positive Acute inflammation (ALT>100) Rejection Cholestasis Hepatic congestion Non fasting state Alcohol Hard to estimate Too fat Too thin Vessels False negative HCV after cure Requires adequate experience to produce reliable results At least 50 scans reviewed by expert Vuppalanchi, Hepatology, 2017

  17. What Does CAP Measure? What Does CAP Measure? Controlled attenuation parameter Ultrasound Attenuation Rate (signal reduction rate) Unit: dB/M (decibels per meter)

  18. ARS Question 3 Which statement is true IN PLWH/HBV 1. HBeAg positivity is lower in PLWH 2. After acute HBV, loss of HBsAg is more common in PLWH than HIV neg 3. Current HBV therapies usually lead to loss of HBsAg 4. ART initiation leads to loss of HBsAg in PLWH

  22. Reactivation of HBV in HIV Reactivation of HBV in HIV High rate of reactivation in immunosuppressed patients Chemotherapy HIV after immune reconstitution Post organ transplant Biologic response modifiers: rituximab (anti-CD20), TNF- inhibitors Lymphoma increased in HIV patients Even in those who have lost HBsAg and are positive for anti-HBc +/- anti-HBs
