RESUMO
Chronic inflammation and immune activation are a hallmark of HIV-1 infection. In this study, we assessed inflammation biomarkers in a cohort of people living with HIV-1 (PLWH) before and after long-term suppressive combined antiretroviral therapy (cART). A single-center prospective cohort study was conducted to assess inflammatory biomarkers in 86 cART-naive PLWH and after receiving suppressive cART and 50 uninfected controls. Tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and soluble CD14 (sCD14) were measured using enzyme-linked immunosorbent assay (ELISA). No significant difference was found in IL-6 levels between cART-naïve PLWH and controls (p = 0.753). In contrast, TNF-α level showed a significant difference between cART naïve-PLWH and controls (p = 0.019). Interestingly, IL-6 and TNF-α levels were significantly decreased in PLWH after cART (p < 0.0001). The sCD14 showed no significant difference between cART-naïve patients and controls (p = 0.839) and similar levels were observed in pre- and post-treatment (p = 0.719). Our results highlight the critical importance of early treatment to reduce inflammation and its consequences during HIV infection.

INTRODUCTION: The nutritional diagnosis and early nutritional management of COVID-19 patients must be integrated into the overall therapeutic strategy. The aim of our study is to assess the nutritional status of patients with COVID-19 after a stay in intensive care, to describe the prevalence of undernutrition, to determine the factors influencing undernutrition and to describe the nutritional management. TOOLS AND METHODS: This is a descriptive observational study of adult patients admitted to the endocrinology service for additional care after a stay in intensive care during the period from April 17, 2020 to May 26, 2020. The assessment tool used was the Mini Nutritional Assessment (MNA). RESULTS: Our study included 41 patients; the average age of the patients was 55 years, 51.2% had a severe or critical form of COVID-19, 75.6% stayed in intensive care, 12.2% had a loss of autonomy. The average BMI was 25.2 kg/m2 (17-42 kg/m2), 42.5% were overweight, 61% had weight loss, 26.2% had weight loss greater than 10%, 14.6% of our patients were undernourished, 65.9% were at risk of undernutrition, 19.5% had hypoalbuminemia, 17.1% had hypoprotidemia, 19.5% hypocalcemia, 34.1% anemia, 12.2% hypomagnesemia and 51.2% had a deficiency in vitamin D. A positive correlation was found between poor nutritional status and a longer stay in intensive care (>5 days) (p = 0.011) and lymphopenia (p = 0,02). CONCLUSION: Despite a personalized diet, 14.6% of patients presented undernutrition. Particular attention should be paid to patients with a long stay in intensive care.

BACKGROUND: In Morocco, of the estimated 29,000 people living with HIV in 2011, only 20% were aware of their HIV status. More than half of diagnoses were at the AIDS stage. We assumed that people who were unaware of their infection had contacts with the healthcare system for HIV indicators that might prompt the healthcare provider to offer a test. The aim was to assess missed opportunities for HIV testing in patients newly diagnosed with HIV who accessed care in Morocco. METHODS: A cross-sectional study was conducted in 2012-2013 in six Moroccan HIV centers. Participants were aged ≥18, and had sought care within 6 months after their HIV diagnosis. A standardized questionnaire administered during a face-to-face interview collected the patient's characteristics at HIV diagnosis, HIV testing and medical history. Contacts with care and the occurrence of clinical conditions were assessed during the 3 years prior to HIV diagnosis. Over this period, we assessed whether healthcare providers had offered HIV testing to patients with HIV-related clinical or behavioral conditions. RESULTS: We enrolled 650 newly HIV-diagnosed patients (median age: 35, women: 55%, heterosexuals: 81%, diagnosed with AIDS or CD4 < 200 cells/mm3: 63%). During the 3 years prior to the HIV diagnosis, 71% (n = 463) of participants had ≥1 contact with the healthcare system. Of 323 people with HIV-related clinical conditions, 22% did not seek care for them and 9% sought care and were offered an HIV test by a healthcare provider. The remaining 69% were not offered a test and were considered as missed opportunities for HIV testing. Of men who have sex with men, 83% did not address their sexual behavior with their healthcare provider, 11% were not offered HIV testing, while 6% were offered HIV testing after reporting their sexual behavior to their provider. CONCLUSIONS: Among people who actually sought care during the period of probable infection, many opportunities for HIV testing, based on at-risk behaviors or clinical signs, were missed. This highlights the need to improve the recognition of HIV clinical indicators by physicians, further expand community-based HIV testing by lay providers, and implement self-testing to increase accessibility and privacy.

BACKGROUND & AIMS: Chronic Hepatitis C is one of the most important risk factors of liver cirrhosis and hepatocellular carcinoma. Before reaching these ultimate steps, insulin resistance triggered by hepatitis C virus infection is known to participate in the progression of liver disease. The present study aims to investigate the influence of two functional polymorphisms on SOCS3 mRNA expression and on the outcomes of CHC progression in a North African context. PATIENTS & METHODS: In this case-control study, 601 Moroccan subjects composed of 200 healthy controls, 101 resolvers and 300 patients with persistent HCV infection including 95 mild chronic hepatitis, 131 Advanced Liver Diseases and 74 HCC were enrolled. They were genotyped for the 4874 A/G (rs4969170) and Aâ¯+â¯930-â¯>â¯G (rs4969168) SOCS3 variants using TaqMan SNPs assays. SOCS3 mRNA expression was assessed using Real Time PCR technique. RESULTS: Logistic regression analysis showed that variation at rs4969168 was associated with spontaneous clearance of HCV (Pâ¯<â¯0.05). In addition, minor allele frequencies were significantly higher in AdLD patients when compared to the mCHC group both for rs4969168 (Pâ¯=â¯7.0 E-04) and rs4969170 (Pâ¯=â¯4.0 E-05). A significant association between haplotype and liver disease progression was also found. Moreover, SOCS3 mRNA was significantly more expressed in peripheral leukocytes from patients with HCC than in those from mCHC. Finally, rs4969170 was significantly associated with LDL-lipoprotein (Pâ¯=â¯0.04), total cholesterol (Pâ¯=â¯5.0 E-04), and higher fasting glucose levels (Pâ¯=â¯0.005) in patients with persistent HCV infection. CONCLUSIONS: Our results underline the importance of the functional SOCS3 polymorphisms in the modulation of CHC progression and suggest their contribution to HCC development by affecting its mRNA expression and perturbing key metabolic parameters.

BACKGROUND: Human papillomavirus (HPV) is the most common sexually transmitted agent worldwide. HPV is the main causative agent for cervical cancer. The HPV oncoprotein E6 binds to the tumor suppressor gene product p53, promoting its degradation; the Arg allele of TP53 R72P polymorphism binds more ardently with HPV E6 than the Pro variant. Here, we investigated whether TP53 R72P gene variant, rs104252, was associated with susceptibility to HPV infection in women with human immunodeficiency virus (HIV). METHODS: We analyzed 200 HPV-positive and 68 uninfected women with HIV. Genomic DNA was isolated from cervical swab. The TP53 R72P polymorphism was genotyped by PCR-RFLP. Unconditional logistic regression was used to assess the association between polymorphism and the clinical, lifestyle, and behavioral data. RESULTS: The genotype and allele frequencies of rs104252 variant did not differ between women without or with HPV infection (P > 0.05). Moreover, the p53 polymorphism was not associated with cervical cytology. In contrast, when we analyzed according to behavior factors, the P72P genotype was more frequent among HPV-positive smoker women. However, no significant relationship was found between alcohol, contraceptive use, and number of partners with TP53 R72P genotype distributions among HPV-positive cases (P > 0.05). CONCLUSIONS: The R72 variant of p53 R72P is not associated with HPV infection and progression of lesions. There was no association between this variant and behavior factors in HPV-positive cases. The P72P genotype may be more frequent among HPV-positive smoker women.
RESUMO
BACKGROUND: Changes in CD4 cell counts are poorly documented in individuals with low or moderate-level viremia while on antiretroviral treatment (ART) in resource-limited settings. We assessed the impact of on-going HIV-RNA replication on CD4 cell count slopes in patients treated with a first-line combination ART. METHOD: Naïve patients on a first-line ART regimen with at least two measures of HIV-RNA available after ART initiation were included in the study. The relationships between mean CD4 cell count change and HIV-RNA at 6 and 12 months after ART initiation (M6 and M12) were assessed by linear mixed models adjusted for gender, age, clinical stage and year of starting ART. RESULTS: 3,338 patients were included (14 cohorts, 64% female) and the group had the following characteristics: a median follow-up time of 1.6 years, a median age of 34 years, and a median CD4 cell count at ART initiation of 107 cells/µL. All patients with suppressed HIV-RNA at M12 had a continuous increase in CD4 cell count up to 18 months after treatment initiation. By contrast, any degree of HIV-RNA replication both at M6 and M12 was associated with a flat or a decreasing CD4 cell count slope. Multivariable analysis using HIV-RNA thresholds of 10,000 and 5,000 copies confirmed the significant effect of HIV-RNA on CD4 cell counts both at M6 and M12. CONCLUSION: In routinely monitored patients on an NNRTI-based first-line ART, on-going low-level HIV-RNA replication was associated with a poor immune outcome in patients who had detectable levels of the virus after one year of ART.

OBJECTIVE: To describe the causes of death occurring during the antiretroviral therapy in Casablanca. METHODS: Retrospective study of a cohort of HIV positive patients attending the infectious diseases unit of Casablanca receiving antiretroviral therapy. Files of 91 patients who died were analyzed. RESULTS: Since June 1999, 1243 patients were treated and 91 deaths occurred (7, 3%). The mean age at time of death was 36 years. Forty-six patients were male (50, 5%) and 86 were stage C (94, 5%). At the initiation of treatment, mean CD4 count was 96 cells/mL (1-626) and mean plasma HIV- RNA was 5, 65 log10. They have received antiretroviral therapy for a mean of 9 months (1-48 months). At time of death, 37 patients (52, 8%) had a CD4 count greater than 200 cells/mL and 16 patients (23%) had undetectable plasma viral load. In 57 cases (63%), the death occurred within the first year after start of antiretroviral therapy. The main causes of death were: tuberculosis (35%), cryptosporidiosis (19%), cryptococcosis (13%), cerebral toxoplasmosis (9%), Kaposi sarcoma (6%), non Hodgkin's lymphoma (2%), atypical mycobacteriosis (2%), cerebral lymphoma (1%), aspergillosis (1%), HIV wasting syndrome (1%) and cancer of cervix (1%). Non AIDS related deaths were noticed in three cases (3%) and the immune reconstitution inflammatory syndrome in six cases (7%). CONCLUSION: In Casablanca, the main cause of death among HIV-infected patients is tuberculosis. Collaboration between the national tuberculosis and AIDS programs has been established to improve the prevention, detection, diagnosis and management of HIV/tuberculosis co infection.
