Objectives

Objectives

  • Highlight common and less common infectious complications of HIV/AIDS.

  • Generate discussion on factors that can impact the outcomes of these infections.

  • Generate discussion on when to start HAART in the face of acute OIs.


Case i ii

Case I & II

Case I

  • 42 years old Female presented with cough, purulent sputum, respiratory distress and fever of 2 weeks duration

  • T=1030 F, RR=32 /min, chest- rales and basal dullness

    Case II

  • 28 years old Female with similar history, had completed treatment for TB; sputum was blood tinged

  • T=1010F, RR=28, chest-rales

  • Both were HIV+

Diagnosis: Severe bacterial pneumonia; Empyema

Case I Case II

  • Outcomealive with CD4Expired in 2weeks

    600+ in 2008

    What modifiable factors might have contributed to the difference in outcome?

    • Supportive care- oxygen, chest tube, close monitoring

    • Knowledge and skill gap?

    • Attitude of the HW or client?

    • Availability of services( diagnostic, therapeutic) and skilled manpower

  • Up to 25% of cases may not have identifiable bacteria but respond to antibiotics


Infectious etiology in hiv bacterial fungal

Infectious etiology in HIV(bacterial/fungal)


Bacterial infections in hiv aids

Bacterial Infections in HIV/AIDS

  • Bacterial pneumonia is a major cause of morbidity and mortality in HIV/AIDS

  • Choice of empiric therapy should target potential causative agents

  • Severe pneumonia if recognized early is treatable


Case iii

Case III

HI: 39 years old male diagnosed with HIV a month ago presented with weight loss (10 kg in 2 months) weakness and diarrhea of 3 weeks duration

  • PMH: Cough, hemoptysis and fever 6 weeks ago and improved with Amoxicillin

  • P/E :Sick looking, cachectic, multiple papular skin lesions on the face; dry scaly skin.

  • Lab: CD4= 7/mm3

    : VL= 392,627c/ml

    :Tuberculin skin test-no induration.

Culture result

Culture Result

  • Gram variable Coccobacilli

  • Weakly Acid Fast

    Identification: Rhodoccous equi

    Management

  • Antibiotic: Clarithromycin, Vancomycin

  • HAART: Combivir/Kaletra

  • Prophylaxis: TMP/SMX, Azithtromycin

  • Patient fully recovered; CD4 =400 in 2008


R equi pneumonia in aids

R.equi Pneumonia in AIDS

  • Presentation is sub acute with productive cough & occasional hemoptysis

  • CXR: infiltrates, nodules, cavities, abscess, empyema

  • CD4 < 100;bacteremia is common

  • Treatment: two antibiotics for > 6 wks; generally resistant to Penicillin/Cephalosporin

  • Prognosis in the era of HAART is good.


Case iv

Case IV

  • 37 years old Hispanic male from central America presented with fever, headache and weight loss of two weeks duration.

  • P/E: cachetic, sick looking, T=1010F

  • Umblicated papular lesions on face.

  • VL=750,000 c/ml.

  • CXR=NAD

  • CT of head-No abnormality

    Clinical Decision

  • CSF: India ink-positive

    : WBC =18/mm3 with 83% L; 9% N

    : OP = 250 mmH2o

  • Crypt Ag=1:1024

  • Ampho. B 0.7mg/kg/d + Flucytosine

  • Started on Kaletra, AZT+3TC, Azithromycin

  • Improved and discharged on Fluconazole 600mg PO daily.

Follow Up continued..

  • 7 wks later he presented with fever, dizziness, cough and vomiting after being found unconscious in the bath room.

  • T= 101oF, bil. basal rales, CNS :a & o, non focal.

  • WBC=20,500/mm3 with 80%N;13%Bands

  • CXR=bilateral infiltrates; LML cavity

  • CT head- cerebral edema, no mass, no herniation.

    Clinical Decision


Case iv follow up

Case IV follow up

  • Admitted to ICU, started on Pipercillin-Tazobactam,Vancomycin, Amphotericin B, IV Fluconazole, Dexamethasone

  • LP done: OP= 400 mmH2o, India Ink was positive, Lumbar drain & intra thecal Amphotericin B.

  • Patient deteriorated and died after 3 weeks of hospitalization.

    Clinical Discussion

  • What is the cause of death?

    • Overwhelming Cryptococcal meningitis?,

    • Bacterial super infection? Aspiration pneumonia?

    • IRIS?, (?paradoxical;?unmasking)

  • Acute necrotizing Bronchopneumonia

  • Left lower lung cavity- Cryptococcal abscess

  • Necrotizing granuloma with numerous budding yeast in para tracheal mass

  • Budding yeast in spinal cord

  • Blood culture= Pseudomonas (post mortem)

Prognostic factors in Cryptococcal Meningitis


Early vs delayed haart in the setting of acute ois

Early Vs Delayed HAART in the setting of Acute OIs

  • 282 subjects; PCP 63%; Crypt. 12%, bacterial infection 12 %. Early HAART had fewer AIDS progression/ death, OR=0.51, CI (0.27-0.94). No difference in safety, toxicity, IRIS at week 48.1

  • 54 Crypt. meningitis cases treated with Fluconazole, early HAART ( with in 72 hrs) had greater mortality (82%) Vs delayed HAART (10 weeks), 32 % overall mortality 62 %.2

Cause specific mortality and contribution of iris in urban cohort

Cause specific mortality and contribution of IRIS in Urban cohort

Method: Determination of cause specific mortality and role of IRIS over 36 months at the IDI of Makerere University.

Result:

  • 17% (90) died in 36 months

  • 14 %(80) died with in the 1st year

  • (13%) 73 patients died with in the 1st three months

    Causes of death

  • 69/80 deaths that occurred during the 1st year were AIDS related

  • Only four were attributed to IRIS

Summary

Summary

  • Progressive decline in CD4 count increases the risk to all infections

  • Bacterial infections (non TB) are common in HIV/AIDS

  • Early HAART leads to better outcome

  • Cryptococcus remains a common cause of mortality

  • IRIS complicates early management of HIV but may not be enough to delay ART
