Diffuse Kaposi sarcoma with oral involvement in a person diagnosed with human immunodeficiency virus/acquired immune deficiency syndrome: A case report.

Kaposi's sarcoma is a well-known multifocal vascular tumor initially described by pathologist Moritz Kaposi. This report presents the case of a 38-year-old bisexual male who consulted the infectious diseases department with non-itchy maculopapular and purpuric lesions on the skin with the involvement of the oral mucosa, suggesting a diagnosis of Kaposi's sarcoma. Biological and radiological investigations were performed. The patient was found to be human immunodeficiency virus positive with a viral load of 251.000/mL and a CD4 count of 182/mm3. In addition, secondary syphilis was diagnosed. Histopathological examinations confirmed HHV-8 KS. The patient was treated with Extencilline® and antiretroviral therapy. After 10 months of chemotherapy, a favorable outcome was noted with complete resolution of skin and oral mucosa lesions.

Salivary biochemical parameters in people living with HIV on ART and dental caries: a cross-sectional study in Monastir, Tunisia.

BACKGROUND: Studies regarding salivary biochemical parameters and dental caries in adult people living with HIV/AIDS (PLWHA) are scanty. AIM: To investigate salivary biochemical parameters and dental caries in adult PLWHA who are on antiretroviral therapy (ART) and compare the findings with people negative for HIV infection. METHODS: The study included 50 HIV positive individuals as a test group (TG) and 50 HIV negative individuals as a control group (CG). Dental examination was performed according to WHO guidelines to assess DMFT. Digital panoramic radiographs were taken to detect additional infectious foci. Non-stimulated saliva was collected between 9 and 12 a. m for 5 min to evaluate 18 biochemical parameters and salivary flow rate (SFR). Parametric and non parametric tests were used according to data distribution. The level of significance was set at p < 0.05%. RESULTS: Patients' mean ages and M/F sex ratios for TG and CG were 38.80 ± 9.69 y/o. vs. 37.98 ± 13.47 y/o. and 3.54 vs. 2.33, respectively. Higher means of decayed teeth were recorded in TG, 4.47 ± 3.00 vs. 3.88 ± 2.81 in CG with no significant difference (p = 0.41). Means of filled teeth were significantly lower in TG 2.38 ± 2.16 vs. 4.16 ± 3.35 in CG (p = 0.01), respectively. No statistical significant difference was noted in DMFT indices between the 2 groups (8.04 ± 6.90 vs. 8.52 ± 6.24, p = 0.71). The following salivary parameters were significantly lower in TG compared to CG, respectively: mean SFR 0.44 ± 0.18 ml/min vs. 0.61 ± 0.26 ml/min; median levels of sodium and chlorides, 4 mmol/L and 13.5 mmol/L vs. 9 mmol/L and 19 mmol/L (p < 0.001) and uric acid, 103.50 mmol/L vs. 163 (p = 0.009). However, higher median levels were recorded with calcium, 1.09 mmol/L vs. 0.54 (p < 0.001) and sIgA 23 mg/dl vs. 5 mg/dl (p < 0.001). In TG, a positive correlation was found between DC, potassium, urea, and chlorides (p < 0.05). Salivary renal and hepatic biomarkers were comparable between the two groups. CONCLUSIONS: PLWHA have shown an alteration in some salivary parameters, more decayed teeth and less filled teeth. Preventive measures should be implemented to lower dental caries and enhance accessibility to oral care services. In addition, saliva can be utilized to monitor oral and general health status among PLWHA on ART.

Quality of Life of People Living with HIV on Antiretroviral Therapy: A Cross-Sectional Study in Monastir, Tunisia.

Introduction: Despite the benefits of an efficient antiretroviral therapy (ART), HIV/AIDS epidemic still represents the most seriousaffection worldwide that negatively impacts people's quality of life (QoL). As no studies exist on QoL in Tunisia, the aim of the present work was i: to assess, based on WHOQOL-HIV BREF tool, the perception of QoL of people living with HIV (PLHIV) receiving ART and ii: to investigate the relationship between socio-demographic features, disease-related variables and QoL domains' mean scores. Methods: This cross-sectional study was conducted at the department of infectious diseases of F. Bourguiba Teaching Hospital in Monastir, Tunisia. One hundred and five participants receiving ART were involved. QoL assessment was based on the WHOQOL-HIV Bref including six domains with 29 items with scores ranged from the lowest (4) to the highest (20). Results were reported as frequencies and means (±SD). The Student's t-test for independent samples and the one-way ANOVA were performed to assess differences in QoL mean scores. Linear regression analysis was used to investigate predictors of QoL. The confidence interval was set at 95%. Results: Clients' mean age was 39.20±10.18 years old with a male to female sex ratio of 3.12. Low mean scores were seen with the environment (12.34±2.90), social relations (12.58±3.94) and psychological domains (12.76±3.31), and moderate mean scores were noted for the physical (14.11±3.52), the spiritual (14.05±3.78) and the level of independence (13.98±3.57) domains. Regression analysis showed that health status and feeling healthy were related to all QoL domains and that profession, marital status and the presence of a confident person were related to environment and spiritual domains. Conclusion: QoL of PLHIV on ART is affected. Concrete measures and strategies should be undertaken by healthcare stakeholders to improve QoL determinants.

Cerebral nocardiosis with osteomyelitis of skull vault complicating a primary neck lesion in an immunocompetent patient: a case report.

Nocardia infection is an uncommon and rare condition in immunocompetent patient. A case of cutaneous nocardiosis complicated with osteomyelitis of the vault scalp in a 64-year-old man, with no remarkable past medical history, is reported. Treatment with trimethoprime-sulfamethoxazole than doxycycline for 12 months led to complete resolution and no evidence of recurrence was noted. Nocardia infection should be considered even in immunocomptent patients and doxycycline is a good alternative for treatment.

The role of quantitative HBsAg in the natural history of e antigen-negative chronic hepatitis B: A Tunisian prospective study.

BACKGROUND/AIMS: During the natural course of Chronic Hepatitis B (CHB) infection, differentiation between inactive carrier (IC) and HBeAg negative CHB is a subject of ongoing debate. We studied the role of hepatitis B surface antigen (HBsAg) level as a means of differentiating between CHB and IC in a group of untreated chronic HBeAg-negative HBV-infected patients. STUDY: A total of 115 HBeAg negative carriers were enrolled and followed up for>12 months; 78 as inactive carriers (IC), and 37 as active carriers (AC). Among ACs, patients were categorized according to the highest rate of viral load: AC1 (n=23), active carriers with persistent HBV-DNA<20,000 IU/mL; AC2 (n=14), active carriers with HBV-DNA>20,000 IU/mL. RESULTS: HBsAg levels were higher in AC compared to IC patients (1607 IU/ml vs. 225 IU/ml respectively, P=0.001). Among the AC group, the 23 AC1 cases had HBsAg levels significantly lower than the 14 AC2 patients (1756 IU/mL vs. 3327 IU/mL respectively; P<10-3). HBsAg showed weak correlation with HBV-DNA in the whole cohort (r=0.44, P<0.01). The suggested cutoff value of HBsAg titer to differentiate between the two groups was 938 IU/mL. Combined single-point quantification of HBsAg (938 IU/mL) and HBV DNA (2000 IU/mL) identified IC with 87.2% specificity and 91.7% positive predictive value. CONCLUSION: This study confirms the predictability of a one-time combined HBsAg and HBV DNA measurement for true inactive carriers requiring neither strict follow-up nor antiviral treatment.

Successful treatment of postoperative multidrug-resistant Acinetobacter baumannii meningitis by tigecycline.

Tigecycline is a broad-spectrum antibiotic with activity against multidrug-resistant (MDR) bacteria. It has limited indications. Studies are necessary to elaborate new guidelines. Here we report a case of postoperative MDR Acinetobacter baumannii meningitis treated by tigecycline combined with colimycin for 21 days. The treatment was well tolerated with a favourable outcome. In conclusion, tigecycline was shown to be effective in a case of MDR A. baumannii meningitis.
