1STAGING OF HIV INFECTION, COMMON AND OPPORTUNISTIC INFECTIONS
2Key QuestionsWhy do we need to do Staging of HIV in infected children?What are the different methods of staging?What are the common opportunistic infections in HIV infected children and how do you treat them?What tool can I use to easily identify , stage and treat OI’s in HIV infected children?
3Why do we do Staging?Provides a guide to the timing of initiation of ARTProvides a guide to prognosis and interventions needed at the different stagesProvides guidance in monitoring response to therapy (treatment failure or improvement).
4How do we stage? Clinical staging: Immunological staging WHO staging-commonly usedImmunological stagingCD4 count
5How many clinical stages are in the WHO clinical staging criteria? ClassificationWHO clinical stageAsymptomatic1Mild2Advanced3Severe4
6Immunological Staging Differences in CD4 counts between adults and childrenAbsolute CD4 count varies with ageAbsolute CD4 count is higher in healthy children than in adults.Cut-off CD4 counts CHANGE with agein children < 5 years; CD4 percentage more constant
7CD4% does NOT change with age. CD4 Pattern in Young ChildrenCD4 counts are high in healthy young children.Decline to adult levels by 6 yrs.CD4% does NOT change with age.
8WHO Immunological Staging Classification of HIV associated immune deficiencyAge-related CD4 values≤11 months (%)12-35 months (%)36-59 months (%)≥5 yrs (cells/mm3)Not Significant>35>30>25>500Mild30-3525-3020 -25Advanced20-2515-20Severe<25<20<15<200 or <15%
10No HIV related symptoms reported and no signs on examination. WHO STAGE 1AsymptomaticClinical diagnosisNo HIV related symptoms reported and no signs on examination.
11Persistent generalized lymphadenopathy (PGL) WHO STAGE 1Persistent generalized lymphadenopathy (PGL)Clinical signs and symptomsSwollen or enlarged lymph nodes >1 cm at two or more non-contiguous sites, without known cause
13WHO clinical stage 3Moderate Unexplained malnutrition not adequately responding to standard therapyUnexplained persistent diarrhea (14 days or more)Unexplained persistent fever (>37.5OC, intermittent or constant >1 mo)Persistent oral candidiasis (after 6 weeks of life)Oral hairy leukoplakiaAcute necrotizing ulcerative gingivitis/periodontisLymph node TBPulmonary tuberculosisSevere recurrent bacterial pneumoniaSymptomatic Lymphoid interstitial pneumonitis (LIP)Chronic HIV-associated lung disease including bronchiectasisUnexplained anemia (<8 gm/dL), neutropenia (<1,000/mm3 ), or chronic thrombocytopenia (<50,000/mm3) for >1 month.
14Unexplained persistent Fever WHO clinical Stage 3Unexplained Persistent Diarrhea: Unexplained persistent (14 days or more) diarrhea(loose or watery stool, three or more times daily) not responding to standard treatmentUnexplained persistent FeverReports of fever or night sweats for longer than one month.Intermittent or constantReported lack of response to antibiotics or antimalarials.No other obvious foci of disease reported or found onexamination.Malaria must be excluded
15In older children, productive cough and haemoptysis as well. WHO clinical Stage 3Severe recurrent bacterial pneumonia Cough with fast breathing, chest in drawing, nasal flaring, wheezing and grunting. Crackles or consolidation on auscultation. Responds to course of antibiotics. Current episode plus one or more in previous six months.Pulmonary TBNon-specific symptoms, e.g. chronic cough, fever, night sweats, anorexia and weight loss.In older children, productive cough and haemoptysis aswell.Abnormal CXR.
16WHO clinical stage 4Unexplained severe wasting, or severe malnutrition not adequately responding to standard therapyPneumocystis pneumonia (PCP).Recurrent severe presumed bacterial infection e.g. empyema, pyomyositis, bone/joint infections, meningitis, but excluding pneumoniaChronic herpes simplex infectionExtrapulmonary tuberculosisKaposi’s SarcomaEsophageal candidiasis (Candida of trachea, bronchi or lungs)CNS toxoplasmosisHIV encephalopathyCMV infection, retinitis or infection affecting other organsExtrapulmonary cryptococcosis, including meningitis
18Recurrent severe bacterial infection WHO clinical Stage 4Recurrent severe bacterial infectionTypes of recurrent severebacterial infectionsEmpyemaPyomyositisBone or Joint infectionMeningitisExcluding PneumoniaSigns and SymptomsFever accompanied by specific symptoms or signs that localizeinfection.Current episode plus one or more in previous six monthsTreatmentAntibiotic treatmentWhen there pus- Do I&D

20Pneumocystis Pneumonia WHO clinical Stage 4Pneumocystis PneumoniaCaused by Pneumocystis Jiroveci (fungus)Major cause of mortality and morbidity in HIV infected childrenClinical presentation:Usually less than 1 yearCoughFast breathingDifficulty in breathingLow grade fever or afebrileHypoxemia (paO2 < 90%)
21Management Supportive IV Cotrimoxazole Oxygen/ventilatory support WHO clinical Stage 4ManagementSupportiveOxygen/ventilatory supportMaintain and monitor hydrationNutritional supportContinue therapy for bacterial pneumoniaIV CotrimoxazoleTrimethoprim (TMP): mg/kg/day6-8 hourlySulphamethoxazole (SMX): mgOral CotrimoxazoleTMP: 20 mg/kg/day 6-8 hourlySMX: 100mgORIV Pentamidine 4mg/kg/day ODDapsone 2mg/kg/ODCourse: 2-3 weeksAdd prednisone 2 mg/kg for 7-14 days in severely ill children2121
22PCP Prophylaxis Who Should Receive Prophylaxis? All HIV exposed and HIV infected infants should receive cotrimoxazole prophylaxis from 6 weeks of ageDose: 10 mg/kg daily or Dapsone 2mg/kg daily2222
23Esophageal Candidiasis WHO clinical Stage 4Esophageal CandidiasisCauses painful swallowingResults in inadequate oral intake with consequences of:Dehydration, malnutrition and deathTreatment:Local treatments (Nystatin, GV)Fluconazole 3-6 mg/kg/OD for 2-3 wks.Ketoconazole 5-10mg/kg/in 1or 2 divided dose2323
