  • Walk-in to Emergency department, seen in Yellow Zone
  • It is possible that smokers have an enhanced primary viraemia, secondary to the effects of smoking on the nasal mucosa, and this predisposes pneumonia. Furthermore, a previous report has shown that smoking renders human alveolar macrophages more susceptible to infection by herpes viruses, which could be relevant pathogenetically, although this requires further study.
  • Varicella-Zoster Virus Infection Associated with Acute Liver Failure,
  • The mechanisms involved in this fulminant visceral dissemination in the patients described remains unclear but are most likely related more to the impaired immune function than to the virulence of the VZV strain.
  • Some case report review suggest steroid pulse therapy in severe conditoin ( IV methyprednisolone 1000mg/day x 3 days)
  • I wish you that this CNY 2013 bring u the warmth of love, and the light of wisdomIn your life , unlimited Happiness of life

  • Factors contribute to the Incident• Underhydration in ward for the past 3 days• Delay in starting anti-viral• Failure to control blood sugar in ward• Inadequate fluid resuscitation in ward prior to transferring patient to ICU copyright to anor hidayah
  • Pathophysiology Classical Pathogen & Immune presentation response ImmuneComplications responses Management copyright to anor hidayah
  • Chicken-pox• Member of Herpesviridae• Sharing structural characteristics as a lipid envelope surrounding a nuscleocapsid with icosahendral symmetry – total diameter 180- 200nm• Centrally located DNA 125000 bp in length• little genetic variation copyright to anor hidayah
  • • Reservoir – human, no animal reservoir• Highly contageous – attack rate ~90% in seronegative individuals• Both sexes and all races – equivalent• Dermo & neutrotropic• Disease in children – well tolerated• More severe in adult, pregnant women and immunocompromised  often have hemorrhagic base copyright to anor hidayah
  • • Transmission – direct contact with the rash – Airborne respiratory droplets – vertical transmission mother to baby during pregnancyLocalize replication Seeding to at undefined site Ultimately develop reticuloendothelial (presumably the viremia system nasopharynx) copyright to anor hidayah
  • Signs and symptoms• In healthy children – the disease is generally mild• The illness usually 14–16 days after exposure – Incubation period 10-21 days• Prodromal symptoms : particularly in older children – Low-grade fever preceding skin manifestations by 1-2 D – 24-48 hr before rash • Mild abdominal pain • Mild cough and runny nose – Mild headache – malaise or irritability copyright to anor hidayah
  • Signs and symptoms• red, itchy rash appear first on the scalp, face, trunk• Diffuse and scattered nature• quickly turn into clear fluid-filled vesicles• 24-48 hr later, vesicular fluid become cloudy – recruitment of PNM leucocytes and presence of degenerated cells and debris.• Ultimately vesicle may rupture and release fluid (infectious virus) or reabsorbed• Umbilication of lesion• oropharyngeal, vagina involvement : common• cornial involvement and serious ocular disease : rare• Itching may range from mild to intense copyright to anor hidayah
  • • Vesicle involve cornium and dermis• Degenerative changes balloning, presence of multinucleated giant cells and eosinophilic intranuclear inclusion• Infection at localize blood vessels of the skin resulting in necrosis an epidermal hemorrhage copyright to anor hidayah
  • Immune response• Natural infection induces lifelong immunity• Newborn babies of immune mothers are protected by passively acquired antibodies during their first months of life copyright to anor hidayah
  • HSV• Mechanism of reactivation VZV resulting in Herpes zoster is unknown• Presumedly virus infect dorsal roots ganglia during chicken pox, remain latent until activated• Histopathologic examination  Hemorrhage, edema and lymphocytic infiltration copyright to anor hidayah
  • High-risk groups• High risks of complications – Newborns and infants whose mothers never had chickenpox or the vaccine – Teenagers & Adults – Pregnant women – People whose immune systems are impaired by another disease or condition – People who are taking steroid medications for another disease or condition, such as asthma – People with the skin inflammation eczema copyright to anor hidayah
  • COMPLICATIONS copyright to anor hidayah
  • • herpes zoster shingles • Endocarditis, myocarditis• secondary bacterial skin and • toxic shock-like syndrome soft tissue infections • hepatitis – severe invasive group A • thrombocytopenia streptococcal infection increases the risk - fold* hemorrhegic varicella• bacteremia • cerebellar ataxia• pneumonitis • encephalitis• osteomyelitis• septic arthritis• Coagulopathy, DIVC copyright to anor hidayah
  • VZV CNS infection• Aseptic meningitis and encephalitis• In many cases of aseptic meningitis – no etiology is identified – VZV has been identified as the 3rd most common cause after herpes virus and enterovirus. copyright to anor hidayah
  • Classic meningeal signs Classical Encephalitis signs• Headache • Altered level of conciousness • Confusion• neck stiffness • Behavioural abnormalities • Hallucination• Photophobia • Agitation• present with or without • Personality changes a preceding rash. • Frank psychotic state• typically have pleocytosis• elevated protein on CSF analysis• Prompt treatment with high-dose intravenous acyclovir on an empiric basis is typically the standard of care. copyright to anor hidayah
  • Varicella pneumonia• The most common and serious complication• Reported incidence in healthy adults that is 25-fold greater than in children• Varicella pneumonia is so uncommon – large-scale studies are difficult to conduct – most published studies represent either collections of small case series or retrospective analyses over many years. copyright to anor hidayah
  • • Varicella pneumonia usually presents 1–6 days after the onset of the rash – Tachypnoea – chest tightness – Cough – Dyspnoea, – Fever – Occasionally with pleuretic chest pain – haemoptysis.• Physical findings are often minimal and chest radiographs typically reveal nodular or interstitial pneumonitis• With the exception of hypoxia, physical signs are a poor guide of severity copyright to anor hidayah
  • • There is a strong correlation between pneumonia and the development of new respiratory symptoms.• increased risk in smoker• Increased number of skin spots (>100 spots), i.e. severity of rash, was a factor that increased the risk of developing pneumonia, may be a reflection of enhanced viraemia. copyright to anor hidayah
  • • The pulmonary lesions – endothelial damage in small blood vessels – with focal haemorrhagic necrosis – mononuclear infiltration of alveolar walls – fibrinous exudates with macrophages in the alveoli which contain eosinophilic intranuclear inclusions.• Seems to occur through the bloodstream rather than local extension through the respiratory tree copyright to anor hidayah
  • • Acyclovir reduces mortality and should be used early in the course of illness in patients with suspected or proven chickenpox pneumonia.• Healing with multiple nodular shadow that may be calcified copyright to anor hidayah
  • VZV ARDS• The early start of antiviral agent has been reported in a significant improvement of oxygenations as well as fever and tachypnea• Very rare• Potentially life threatening copyright to anor hidayah
  • Varicella Hepatitis• VZV hepatitis with acute liver failure – Uncommon – frequently fatal condition – The few patients who survived received early acyclovir and Liver transplant – Most of the patients described were immunocompromised copyright to anor hidayah
  • • presenting symptoms – cutaneous varicella lesions – acute abdominal or back pain – fever• The typical papulovesicular rash may precede , be concomitant with or appear delayed relative to the abdominal complaints. Patients with disseminated Varicella appear to remain moderately ill for some days and then go on to develop full-scale liver failure with coagulation disturbances and shock. copyright to anor hidayah
  • • The mechanisms  remains unclear• Most likely related more to the impaired immune function than to the virulence of the VZV strain.• Infection usually appears to be primary infection• Histopathologic examination of the liver contributes to the diagnosis copyright to anor hidayah
  • VZV Rhabdomyolysis• Elevated CK and myoglobin• Muscle damage was likely to account for some part of the elevations of AST and LDH• Very rare• Carries good prognosis• Aggressive fluid therapy to protect against renal failure copyright to anor hidayah
  • Treatment• Treatment approaches – supportive measures eg Hydration – antiviral therapy – varicella zoster immune globulin (VZIG) ( 5g/day x 5days) – management of secondary bacterial infection. – Recognize underlying co-morbid eg: DKA• Early recognition of secondary bacterial infections. Failure to recognize occult infection may result in serious illness and even death. copyright to anor hidayah
  • Acyclovir therapy• Oral 800mg 4 times /day for 5-7days• Recommended for adolecents and adults < 24 hrs of infection• More effective in HZV infection – accelerated healing of lesions, resolution of Zoster associated pain• In Severe Chickenpox infection, should be treated at the onset  reduce occurrence of visceral complications copyright to anor hidayah
  • • Penetration into CSF  Excellent ~ 50% of serum level• Complications: – Increase urea and increase creatinine ~5% – Thrombocytopenia ~ 6% – Gastrointestinal ~ 7% – Neurotoxicity ~ 1% copyright to anor hidayah
  • Varicella Vaccine• Live attenuated vaccine (Oka)• Recommended in all children > 1 yr age and seronegative adult copyright to anor hidayah
  • Varicella Immunoglobulin• special consideration in Adults – not received the vaccine – not already had chickenpox – higher risk for exposure/transmission Temporary protection of non-immune individuals can be obtained by injection of varicella-zoster immune globulin within 3 days of exposure The immunity acquired in the course of varicella prevents neither the establishment of a latent VZV infection, nor the possibility of subsequent reactivation as zoster copyright to anor hidayah
