Abstract
HIV-positive patients have an increased risk of hyperglycemia factors associated with infammatory activity and
antirretrovirals treatment, and this can directly impact in survival and life quality. This study proposed to evaluate impact
and risk factors for insulin resistance in HIV patients. Total of 218 patients were included and we detected increase in
glucose levels after HAART initiation (18.5% vs. 36.7%, p=0.0025). High fasting glucose levels were pointed as risk
factor for symptomatic clinic during follow-up (RR=1.35; IC 95% 1,01-1,80; p=0.002), and higher monocyte/lymphocyte
ratio was associated with hospitalization after treatment start (p=0.033).

Introduction
Peripheral Insulin resistance has been associated to abnormal
body fat distribution, changes in lipid and carbohydrate metabolism,
persistence of infammatory system activation, and antiretroviral
therapy [1-3]. Alterations in HIV patient’s glycemic profle, as
diabetes, activate infammatory system, especially with higher viral
load and prolonged symptomatic periods [4-6]. Antiretroviral therapy
is associated with a signifcant increase in blood glucose levels by
diferent pathways: increases peripheral insulin resistance modifying
cellular insulin signaling or lipid metabolism, increases homocysteine
levels, blocking glucose interfering with GLUT-4 transporter (protease
inhibitors), or mitochondrial toxicity (nucleoside reverse transcriptase)
[7-13]. Higher total cholesterol/HDL (Castelli Index 1) causes
mitochondrial oxidative stress [14,15].
A study evidenced increases of 2.2 times in hospitalization rates
in diabetic HIV patients, between 1994 and 2004 [16]. Brazil study
evidenced an annual increase of 4.1% in diabetes prevalence of HIV
infected patients [17]. Recently, Shikuma demonstrated a correlation
between increased monocytes cells and peripheral insulin resistance in
HIV patients [18,19]. It was observed decreases in T-CD
4
cells associated
with increased monocytes [20]. Studies are evidencing a possible role of
monocytes in chronic infammatory pathophysiology [21].
Study is a multicenter retrospective cohort, including patients over
18 years, with previous diagnosis of HIV infection and followed up at
Hospital Geral de Fortaleza (HGF) and Clínica Escola de Saúde (CES)
at Unichristus Center University. Te Epi Info sofware 3.5.1 was used
for statistical analysis.
Results and Discussion
Total of 218 patients were included and 161 (73.9%) male. Mean
age was 37.6 ± 11.4 years. Time of follow-up median was 21 months.
Arterial Hypertension prevalence before HIV diagnosis was 10.6%
(N=23), diabetes mellitus 2.8% (N=6) and dyslipidemia 4.1% (N=9).
Final follow-up evidenced 18 patients (8.3%) symptomatic (diarrhea
44.4% and syphilis 38.9%). During monitoring period, were detected
30 patients (13.8%) requiring hospitalization, and 1.8% admitted more
than once. Causes of hospitalization were neurotoxoplasmosis (11
admissions - 36.6%), bacterial pneumonia, pulmonary tuberculosis
and multifocal leukoencephalopathy, each with 3 admissions (10%).
Tenofovir associated to Efavirenz and Lamivudine was started in 62.9%.
Before ARV therapy, 18.6% patients had blood glucose above 100
mg/dL. Afer ARV, prevalence increased to 36.7% (12 months), 44.3%
(26 months) and 45.9% (33 months), (p=0.0025).
Higher glucose levels above 100 mg/dL before antiretroviral
therapy was considered a risk factor for symptoms related to HIV at
fnal follow-up (RR=1.35, 95% CI: 1.01 to 1.80, p=0.002). Tere was a
positive correlation between lower monocytes/lymphocytes ratio and
no admission related to HIV (p=0.01). ART Terapy is essential for
infected patients survival, but it contributes as risk factors for diabetes
and cardiovascular diseases [22-26]. Monocytes/lymphocyte ratio
could be used as infammatory activation biomarker for monitoring,
and signalizing as risk for hospitalization (Table 1).
Monocytes/lymphocytes ratio was controlled in hyperglycemic
group afer start ARV, evidencing immunology control of infammation
related to blood glucose. Most patients had a suppressed viral load
in fnal follow-up (97.3%), witch could not be implicated in hospital
admission. Elevated monocytes levels in HIV patients are associated
with pro-infammatory mediators production and immune alterations
[27,28]. It described an immune system deregulation evidenced by
reduced CD
4+
T cells associated with increased number of monocytes.
However, this was not observed in present study, since monocytes
increased during follow-up as T-CD
4
cells. We also detected unchanged
T-CD
8
cells account, suggesting others possible uncontrolled
infammatory components involved in our population, which must be
studied in future.
