History and Presentation
  • 28 y.o ? known to be HIV for 6 years
  • Admitted to hospital because of jaundice and a
    fever of 102o F
  • Contracted HIV from an old boyfriend who
    subsequently died. Husband refused to be tested
  • Previously treated with anti-retroviral drugs
    poorly tolerated
  • Developed Progressive Wasting Syndrome and
    anemia. Previous fever treated with antibiotics.
  • Current problems Progressive Liver Failure with
    ? liver enzymes and jaundice occuring during the
    past five days accompanied by fever.
  • Physical Exam
  • Cachectic ?, oriented
  • Temp. 101.8 oF
  • BP 100/40
  • HR 88 bpm and regular
  • Skin and sclerae were icteric. No
    lymphadenopathy. Chest clear.
  • Ascites. Liver and spleen markedly enlarged.
    Lower extremities were edematous

What is Progressive Wasting Syndrome? Is
HIV-related anemia related to CD4 or viral load?
Progressive Wasting Syndrome
HIV Anemia
  • Clinical syndrome in which an individual has lost
    more than 10 of his or her body weight in the
    absence of active infections or any other
    identifiable cause of weight loss.
  • One of the most common symptoms of HIV infection
  • Associated with malnutrition, which may
    contribute to increased immune suppression

    EFC89BA-7146-4966-8F39-701651DD559D.htm
  • Anemia is associated with HIV disease
    progression, independent of CD4 count and viral
    load. Most common in patients with CD4
  • Common causes of HIV-related anemia
  • Infections e.g. B19 parovirus
  • cancers of the bone marrow
  • drugs which suppress the bone marrow as a
    side-effect of therapy
  • AZT, foscarnet, ganciclovir, co-trimoxazole (at
    the high doses used to treat PCP anaemia is
    rare at the doses used for PCP prophylaxis) and
    dapsone
  • Bleeding most common reason in HIV-negative m

    patients

CHEMISTRY

Why was Alk. Phosphatase Increased?
  • Alk. Phosphatase
  • Sources
  • Liver hepatocytes and biliary tract mucosal
    cells
  • Bone
  • Intest. Mucosa
  • Placenta
  • Normal adolesc. 3-5x adult values (bone growth)
  • Greater sensitive to biliary tract obstruction
    whether intra or extrahepatic. Does increase with
    liver cell acute injury
  • Hepatic ALP Elevation
  • Extrahepatic bil. Tract obstruct.
  • Intrahepatic bil. Tract obstruct.
  • Liver cell acute injury
  • Liver passive congestion
  • Drug-induced liver cell dysfunction
  • Space occupying lesions
  • Primary biliary cirrhosis
  • Sepsis
  • Dont forget bone or placental origin

8
Why do you think AST is increased so modestly
(1.3 x Upper Range Normal (URN)
  • AST
  • Sources
  • Liver
  • Heart
  • Sk. Musc.
  • RBCs
  • Diseases with mild moderate abnormality
    (
  • Acute hepatitis resolving phase
  • Chronic hepatitis
  • Active cirrhosis
  • Liver passive congestion
  • Drug induced liver dysfunction
  • Metastic liver tumor
  • Bile duct obstruction
  • CMV, inf. Mono
    • In extrahepatic obstruction there usually is no
      elevation unless secondary parenchymal acute
      injury occurs
    • AST/ALT ratio is elevated (1) in active
      alcoholic cirrhosis, liver congestion and
      metastatic tumor to the liver
    • Etiologies for AST Elevation)
    • Heart MI, Pericarditis
    • Sk. Mus. Inflammation, MD, recent surgery, DTs
    • Kidney Acute injury or damage, Renal infarct
    • Other Intest. Infarct., Cholecystitis, shock,
      acute panreatitis, hypoparathyroidism

    9
    GGTP
    • GGTP has equal to or greater sensitivity than ALP
      in obstructive liver disease and greater
      sensitivity in hepatocellular injury (16x URN)
    • Etiologies for GGT Elevation
    • Liver, space-occupying lesion (M-H)
    • Alcoholic active liver disease M)
    • Common bile duct obstruction (M)
    • Intrahepatic cholestatis (M-H)
    • CMV infection, Mono infection (S/M)
    • Tylenol overdose (S/M)
    • Severe liver congestion (S)
    • Reyes syndrome (S)
    • S small, Mmedium, Hhigh

    10
    Questions
    • Discuss the status of the patients liver
    • Hyperbilirubinemia Impaired hepatic excretion
      of conjugated bilirubin. This is not of hemolytic
      origin ? unconjugated bilirubin
    • Hypoalbuminemia and ? protein impaired hepatic
      synthesis and malnutrition
    • ? Calcium as a consequence of ? albumin
    • 50 of total Ca is ionized, the remainder
      protein bound.
    • A ? in serum albumin will ? ? total serum Ca
    • Only hepatitis marker HBsAb. Consistent with
    • Immunization
    • Long ago exposure and recovery with loss of HBcAb
    • No active infection (No HBeAg). No Carrier state
      (No HBsAg HBcAb)
    • Transaminases (AST, ALT) are only modestly
      elevated
    • Ascites and splenomegaly common in patients
      with portal hypertension
    • What is the significance of the depressed amylase
      level?
    • Amylase is typically elevated in pancreatitis, in
      biliary tract disease (cholecystitis, tumor,
      spasm of sphincter of Oddi). In this instance it
      is low
    • Pancreatitis can occur in association with HIV
      therapy (DDI) or more commonly in alcoholic
      patients
    • Because in requires good renal function to clear,
      serum amylase is sometimes elevated in renal
      failure.
    • Pancreatic enzymes are important in the digestion
      of carbohydrates. In a patient losing weight it
      may be helpful to rule/out a digestive disorder

    11
    What are the 3 stages of HIV infection?
    • Acute
    • 3-6 weeks after initial infection
    • Non-specific symptoms resolves spontaenously
    • Fever
    • Rash
    • Myalgia
    • Middle
    • Clinical latency patient asymptomatic, mild
      constitutional symptoms, lymphadenopathy
    • Crisis
    • Immune system breakdown
    • Fever
    • Loss of Weight
    • Diarrhea
    • Opportunistic infections and secondary neoplasms

    Clinical Course
    • Treatment
    • Treated empirically for CMV and mycobacterium
      intracellulaire
    • Diuretics and salt-poor albumin for ascites
    • Liver function continued to deteriorate
    • Patient developed electrolyte imbalance that
      reqd. correction
    • Cytopenia worsened reqd transfusion of several
      units of packed red blood cells
    • Blood and urine culture negative
    • One week later oral and esophageal lesions
    • Grim prognosis discussed. Patient died at home 2
      days later.
    • Antemortem stool culture positive for acid fast
      organisms

    Impact of HIV on acquisition, activation and
    outcome of TB?
    • Acquisition 113 x higher risk of being infected
      than a person with no risk factors
    • Mechanism HIV infects helper-T-cells leading to
      a decrease in cell-mediated immunity. Absence of
      immunity ?development or activation of the
      disease
    • 37 of HIV-infected individuals develop TB within
      5 months of exposure as compared to 5 of
      patients with normal immune system
    • Assessment PPD in HIV ONLY 30-50 of TB
      infected HIV patients will respond with an
      induration 10mm. THUS induration 5mm is
      considered

    22
    HIV Positive Patient. What do you do?
    • Ordinarily INH daily for 12 months
    • Some recommend INH for life since eventual
      failure of the immune system will allow infection
      to progress to active disease
    • If drug-resistant strain start on two drug
      regimen INH and EMB or INH and cipro for
      preventive therapy
    • If an HIV-infected patient develops
      drug-resistant TB the chances of dying from the
      disease are between 72-89, even with aggressive
      therapy!!
    • AIDS patients progress to MDR-TB immediately
      after infection and die within 4-19 weeks

    23
    Esophagus
    • HE x 31
    • Esophagus covered by adherent grey-white membrane
    • Note numerous fungal organisms as bluish wavy
      band across bottom of iimage
    • Inflammatory cells, necrotic debris and
      collections of bacteria near lumen at top
    • Gomori silver stain x100
    • Fungi, numerous yeast and pseudohyphal forms are
      present consistent with Candida species

    24
    Lymph node HE x12
    • Atrophic lymph node
    • Marked depletion of lymphocytes in both mantal
      and germinal centers
    • Germinal centers are small and show signs of
      hyalinization

    25
    Organization of spleen
    • Marginal zone - assortment of mononuclear cells
    • Principal function of the marginal zone is
      antigen trapping.

    • White pulp containing numerous lymphocytes
    • Clearly delineated from the surrounding red pulp
