GOALS • Opportunistic infections • Antiretroviral treatment • Mother-to-Child Transmission • Psychosocial issues • Ethics
HIV TRANSMISSION • Exchange of body fluids • Exchange of infected blood transfusion or by needle piercing • Mother-to-child transmission • 80-90% sexual contact
WHO Classification • Major signs - Weight loss >10% of body weight - Fever more than one month int & cont - Chronic diarrhoea more than one month intermittent and continues
WHO Classification • Minor signs - Persistent cough more than one month - Gen.itchydermatitis - Recurrent, multi-dermatomal herpes zoster - oral candidiasis - Chronic progressive and disseminated herpes simplex - Generalized lymphadenopathy
CDC REVISED CLASSIFICATION • CD4 T-cell A B C >500/ul A1 B1 C1 200-499/ul A2 B2 C2 <200/ul A3 B3C3 A- Asymptomatic or PGL B- Symptomatic C – AIDS indicator
CLASSIFICATION (CD4) • CD4 cell count/ul Stage of HIV disease >500 Early 500 – 200 Intermediate 200 – 50 Late or severe <50 Far Advanced
FIVE GOALS IN HIV CARE • Prevention of further transmission • Preservation of immune function • Prophylaxis against OI • Rx of OI through effective early diagnosis • Counseling and other psychosocial supports
COURSE OF HIV INFECTION • Acute seroconversion syndrome in 1/3rd • Phase of clinical latency • CD4 <200/ul, OI begins to set • Progress to AIDS about 8-10 yrs
OPPORTUNISTIC INFECTIONS • Oral candidiasis - Oral discomfort - Burning sensation when eating - Altered sense of taste - KOH • Oesophageal candidiasis - Odynophagia or dysphagia - Anterior chest pain, exacerbated by swallowing
OPPORTUNISTIC INFECTIONS - DIARRHOEA • Parasitic – Criptosporidium, Isosporabelli Microsporidia, Giardia, EH • Bacteria – Solmonella, Campylobacter, C.difficile, M.tuberculosis
DIARRHOEA • Fungal – Candidiasis, Histoplasmosis • Viral - CMV, HSV, adenovirus, enterovirus, HIV • M.C - Cryptosporidium, Isospora belli & Microsporidium
EMPIRIC ANTIBIOTIC RX • TMP/SMX • Ciprofloxacin • Metronidazole • Paramomycin
COUGH & FEVER • Acute – WBC + abundant bacteria • Sub acute – Few WBC – PCP • Chronic – AFB+ - TB • Malaria, Typhoid, Viral fever • Crypto • Toxo
CNS MANIFESTATIONS • Cryptococcal meningitis • Toxoplasmosis • Tuberculous meningitis • Progressive multi focal leukoencephalopathy • Neurosyphilis • Lymphoma
CT scan post contrast multiple granulomas (arrows) surrounded by minimal vasogenic edema. Presence of multiple lesions with a target sign and positive toxoplasma titre suggest toxoplasmosis
PULMONARY MANIFESTATIONS • Pansinusitis • Pulmonary or extra pulmonary tuberculosis • PCP • CMV
CUTANEOUS MANIFESTATIONS • Infectious dermatoses Viral infections Acute HIV, HSV, VZV EBV HPV
BACTERIAL INFECTIONS • Staphylococcal • Mycobacterial • Bacillary angiomatosis • T.Pallidum infection • Others – Pseudo, salmo, nocardia
FUNGAL INFECTIONS • Superficial dermatophytosis • Candidiasis • Superficial mycoses • Deep infections & systemic mycoses Crypto, histo, coccidio, sporotrichosis, penicilliosis, blastomycosis, aspergillous
PARASITIC INFECTIONS • Arthropod infestations Scabies, demodicidosis • Protozoal infestations Ex-pulmonary pneumocystosis, leishmaniasis, cutaneuous toxo, acanthamoebiasis
NON-INFECTIOUS DERMATOSES • Seborrheic dermatitis, psoriasis, Reiter’s, ichthyosiform dermatoses • Papular and follicular eruption of HIV • Pigmentary idsorders • Adverse cutaneous drug reactions • Neoplasms: Kaposi’s, lymphoma, melanoma
NAIL & HAIR CHANGES • Onychomycosis • Yellowish discoloration of nail • Melanotic bands & black pigmentation of nail due to AZT • Pre-mature graying of hair (Canities) • Diffuse hair loss, male pattern alopecia, alopecia areata, hypertrichosis of the eye lashes

STIs • Syphilis, herpes, chancroid, granuloma inguinale, LGV, gonorrhea, trichomoniasis, bacterial vaginosis, vulvovaginal candidiasis, PID, ano-genital warts
MANAGEMENT • WHO(1997) CDC (1998) • Higher dose of antimicrobials • Prolonged duration of therapy

WOMEN & HIV • OI in women as same in men • Recurrent vulvovaginal candidiasis • Genital herpes, HPV • Bacterial vaginosis & PID • Cervical dysplasia and neoplasia
PAEDIATRIC HIV • Diagnosis based on antibody tests >18 M • Immediate diagnosis – antigen test DNA PCR, p24 antigen
ANTI-RETROVIRAL THERAPY • Clinical goal • Virological goal • Immunological goal • Therapeutic goal • Epidemiological goal
INDICATIONS FOR ART • Acute infection • Symptomatic • Asymptomatic - CD4 <200 to 500 - HIV RNA >20,000 copies - RT-PCR >10,000 copies bDNA
ART • NRTI – AZT, ddI, ddC, d4T, 3TC • NNRTI – Nevi, delavir, efavir • PI - Saq, ritonavir, ind, nelf, ampri • Nucleotides – adefovir, dipivoxil • Miscellaneous – Hydroxurea

PREVENTION OF MOTHER-TO-CHILD TRANSMISSION • ART before, during, after delivery • Infant: AZT syrup 2mg/kg/QID for first six weeks, 8 to 12 hours after birth • LSCS • Postpartum care • Breast feeding with ART
PSYCHOSOCIAL MANAGEMENT • Counseling - Relationship building - Assessment - Goal setting - Intervention - Termination & follow up
ETHICS • Obligation of a physician to treat patients - World medical association (the professional responsibility of physicians in treating AIDS patients) should not refuse to treat a patient, a physician who is not able to provide care and service should refer to equipped hospitals.
ETHICS • Confidentiality - If individual feels that their status will be disclosed and in turn lead to discrimination, they may opt to get tested or treated, and that hinders offers to contain the epidemic
