Diseases of skin and mucous membranes are common clinical manifestations of acquired immunodeficiency syndrome (AIDS).
More than 90% of patients develop skin lesions at some time during the disease.In some patients, skin is the first organ
affected.
INTRODUTION
![Page 3: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/3.jpg)
Impaired skin immune system
occurring early in HIV disease is
believed to be responsible for the
frequent occurrence of both
infectious and non‑infectious skin
diseases
![Page 4: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/4.jpg)
Skin lesions occurrence in HIV infected patients is often atypical and more severe, explosive, extensive or resistant to therapy
![Page 5: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/5.jpg)
Unusual histology of some of the diseases
in AIDS may contribute to misdiagnosis.
Diagnosis of skin manifestations is very
important as it may serve as the earliest
manifestation to suspect a case of HIV
infection

Total 110 known HIV positive patients of all ages with symptomatic skin lesions attending skin and venereal disease out‑patient department and Anti Retroviral Therapy
![Page 8: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/8.jpg)
Patient’s HIV positivity was confirmed by
three different sets of Ag systems
HIV comb‑AIDS Rapidtest
Rapid spot test‑Pareekshak and
Tridot

complete clinical details, in particular skin
lesions were noted along with CD4 counts
when available.
Irrespective of any other systemic
involvement or presence of other STDs,
only skin lesions were sampled after taking
informed written consent.
![Page 10: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/10.jpg)
The lesions were sampled using the punch
biopsy or cytology and the diagnosis was
made with the help of special stains
total 110 patients, 106 punch biopsies
were taken and cytology was done in 25
cases.
![Page 11: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/11.jpg)
The type of cytology sample
varied depending upon the
nature of the lesions
Nodular lesions – FNAC
Ulcerative lesions – scrape
smears
Vesicullobullous - Tzanck smears

DISCUSSION
![Page 27: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/27.jpg)
very few case studies in Indian
patients are available.
No such type of study has been
carried out in Central India.
![Page 28: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/28.jpg)
In our study of 110 HIV infected patients,
CD4 correlation was done in 70 patients.
Maximum patients, i.e., 42 (59%) had CD4
count below 200,
followed by 21 (31%) patients with CD4
counts between 200 and 500,
whereas 7 (10%) patients had CD4 counts
above 500.
![Page 29: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/29.jpg)
![Page 30: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/30.jpg)
Maximum number of infective
lesions were seen in patients with
CD4 counts below 350
whereas patients with CD4 count
above 350 showed minimum
infective, but most of the
non‑infectious lesions
![Page 31: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/31.jpg)
Previous studies showed that
CD4 counts <200 cells/cumm
were associated with more
number of infectious lesions
![Page 32: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/32.jpg)
Munoz‑Perez (1998) study stated
Genital herpes, tinea,
Kaposi’s sarcoma, xerosis, HSV,
Drug eruptions, candidial
folliculitis, M. contagiosum,
psoriasis,abscess,verruca vulgaris,
PPE, oral hairy
Leukoplakia.
![Page 33: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/33.jpg)
Seborrheic dermatitis could be used as clinical markers of disease progression due to their strong association with CD4 counts
![Page 34: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/34.jpg)
We found that 57 out of 110 (52%)
patients had infectious lesions with
Unusual clinical presentations
In these patients, infectious agents
can produce skin lesions even though
the classic organs of involvement for
that agent do not include the skin,
e.g., cryptococcosis,
Cytomegalovirus and histoplasmosis
![Page 35: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/35.jpg)
![Page 36: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/36.jpg)
• We found 30 (27.28%)
patients with viral
lesions.
• Out of 15 cases of M.
contagiosum,
• 2 cases had giant
Molluscum all over the
body
diagnosed first on
FNAC.
• Maximum patients
showed CD4 counts
<200
![Page 37: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/37.jpg)
HPV :
verruca vulgaris, verruca plana
Bowenoid papulosis, condylomata
accuminata
Munoz‑Perez et al. found no
significant difference between the
incidence of condyloma acuminata or
verruca vulgaris in stage III and
stage IV disease or with CD4 counts.
![Page 38: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/38.jpg)
Present study showed no significant
difference in the occurrence of HPV
related lesions in patients with <200 or
>200/cumm CD4 counts.
Munoz‑Perez et al. in their study
mentioned that HIV infection itself
predisposes to an increased risk of HPV
infection that is not directly related to
the degree of immunosuppression.
We found six cases of herpes zoster
infection
![Page 39: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/39.jpg)
Friedman‑ Kien et al. had
mentioned a strong association
between the occurrence of
herpes zoster and incidence of
AIDS.
Nichols et al. stated that bacteria
infections in AIDS were often
under represented.
![Page 40: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/40.jpg)
In our study we found 14
(12.72%) cases of bacterial
infection including
Mycobacterium infections.
Dermatological lesions of
tuberculosis (TB) infection are
rarely found in Western
countries.
![Page 41: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/41.jpg)
Various mycobacterium lesions in our
study were
leprosy (three cases of borderline
tuberculoid and one case of
tuberculoid leprosy),
Papulonecrotic tuberculid (2),
scrofuloderma and
TB cutis orificialis one each.
![Page 42: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/42.jpg)
Frommel et al. Found no association between leprosy and HIV‑1 infection; he had mentioned that it does not seem to alter its course.
![Page 43: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/43.jpg)
We found six cases of fungal lesions which
included
two cases of dermatophytoses and candidiasis
one case each of histoplasmosis and
cryptococcosis.

We found 7 (6.36%) cases of parasitic
infection, which included six cases of
demodicidosis and one case of scabies.
Kaplan et al. reported four cases of scabies
who presented with pruritic dermatitis
Clinically, the lesions of scabies may
resemble
psoriasis vulgaris or
Darier’s disease
![Page 46: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/46.jpg)
The most common non‑infectious
skin manifestation found in our
study was PPE.
They were intensely pruritic,
papular lesions more on the trunk
and extremities with a
predominance of eosinophils as
described by Francis.
African and Haitian patients.
![Page 47: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/47.jpg)
Hevia et al. (1991) mentioned
histological and clinical criteria for
the diagnosis of these lesions.
Most of the cases of PPE in our study
were seen with CD4 counts more
than 350 cells/cumm.
![Page 48: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/48.jpg)
We found three cases of eosinophilic
folliculitis.
Rosenthal et al. found its association
in patients with CD4 counts between
200 and 500 cells/ cumm.
It could be an important clinical
marker of HIV infection, particularly
in patients at increased risk of
developing opportunistic infection.
![Page 49: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/49.jpg)
The clinical and histological
differential diagnoses of
eosinophilic folliculitis include
demodicidosis and PPE
![Page 50: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/50.jpg)
We found three cases of
psoriasis and
One case of Reiter’s syndrome.
Incidence of psoriasis as high as
70% had been reported by Duvic
et al.
![Page 51: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/51.jpg)
We found 4 cases of seborrheic
dermatitis.
it is mentioned that the incidence of
seborrheic dermatitis is very high
from 40% to 83% in Western
literature
![Page 52: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/52.jpg)
We found one case each of
drug eruption, keratosis pilaris,
porokeratosis, seborrheic keratosis,
lichen planus and papular urticaria
![Page 53: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/53.jpg)
Miscellaneous group included
8 cases of non‑specific dermatitis,
two cases of neutrophilic dermatitis
and
one case each of chronic dermatitis,
Interface dermatitis,
pityriasis rosea,
Panniculitis,
Vasculitis and abscess.
![Page 54: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/54.jpg)
We did not get any case of
neoplastic lesion, i.e.,
Kaposi’s sarcoma, lymphoma or
Any other cutaneous
malignancies.
![Page 55: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/55.jpg)
Wiwanitkit (2004) and D. N.
Lanjewar (2011) also found striking
low prevalence of cutaneous and
other malignancies in these patients.
![Page 56: Dermatology in HIV](https://reader034.fdocuments.in/reader034/viewer/2022050818/558be6edd8b42a6b3a8b46ca/html5/thumbnails/56.jpg)
infectious skin lesions were seen more
commonly with CD4 counts below 350 and
non‑infectious skin lesions were seen more
commonly with CD4 counts more than 350.
The most common infectious lesion was M.
Contagiosum and
most common non‑infectious lesion was PPEStrikingly low occurrence or absence of
cutaneous malignancies

Among the HIV-EF patients, we found an
intense perivascular and diffuse
inflammatory infiltration compared with
those patients with HIV-PPE.
The tissue mast cell count by toluidine
staining was higher in the HIV-EF
patients, who also presented higher
expression levels of CD15 (for
eosinophils), CD4 (T helper), and CD7
(pan-T lymphocytes) than the HIV-PPE
patients.

Based on a review of the literature, 29 reports
Topical therapy is the first-line recommended treatment for mild to moderate disease.
For moderate to severe disease, phototherapy and antiretrovirals are the recommended first-line therapeutic agents.
Oral retinoids may be used as second-line treatment
refractory, severe disease, cautious use of cyclosporine, methotrexate, hydroxyurea, and tumor necrosis factor-a inhibitors may also be considered

In this study 66 (94.3%) patients had at
least one skin problem.
Fungal infections were the most
common
8 MC types of mucocutaneous problems
were gingivitis, pallor, itching,
photosensitivity, seborrheic dermatitis,
candidiasis, folliculitis and tinea
versicolor.
MC manifestation was gingivitis.
