Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disease in which the complement system plays a role in its pathogenesis. Mannose-binding lectin (MBL) is a serum protein, being a component of innate immune system, it is responsible for lectin pathway of complement activation. The presence of several polymorphisms at the coding regions of the MBL-2 gene, especially single point mutation at codon 54, leads to decreased level and /or functional deficits of MBL, which seems to be a risk factor for occurrence of autoimmune diseases, such as in SLE. So, this study was carried out to determine the role of the serum MBL concentration and the genetic polymorphisms of MBL-2 gene exon 1 codon 54 in Egyptian patients with SLE. Forty-eight SLE patients and 48 matched healthy controls were investigated. MBL serum level was measured by ELISA technique. MBL-2 polymorphism at exon 1 codon 54 was determined by PCR-RFLP. Our results revealed a significant reduction in MBL serum level among SLE patient group in comparison to the control group (P < 0.001). MBL-2 genotyping among SLE patients, revealed the wild type (A/A) in 52.1% and mutant types (A/B, B/B) in 47.9%. While among healthy controls, the wild type was detected in 81.2% and the mutant types in 18.8% with a statistically significant association between this polymorphism and SLE susceptibility (P=0.008). Comparison of MBL serum level among different genotypes within the patient group showed that the mutant allele had a suppressive effect on MBL serum level. In conclusion, carrying MBL-2 exon-1 codon 54 variant allele B was shown to be a risk factor for SLE.

Abstract
The reappearance of HCV infection months or years after sustained virologic response (SVR) may be due to the persistence of HCV in tissue cells in spite of being undetected in serum. This situation is known as occult hepatitis C infection (OCI). We aimed to assess the prevalence of OCI in Egyptian patients with chronic hepatitis C (CHC) who achieved SVR after treatment with direct-acting antiviral agents (DAA). We carried out a cross-sectional study at the Advanced Center for Liver Diseases of Zagazig University Hospitals and Al-Ahrar Viral Hepatitis Treatment Center, Sharkia Governorate, Egypt. One hundred and fifty adult patients with CHC, who achieved SVR 12-24 weeks after end of treatment with sofosbuvir/daclatasvir ± ribavirin (139 patients, 92.67%), sofosbuvir/ledipasvir ± ribavirin (eight patients, 5.33%), sofosbuvir/simeprevir (two patients, 1.33%), and ombitasvir/ paritaprevir/ritonavir + ribavirin (one patient, 0.67%), according to the Egyptian National Committee for Control of Viral Hepatitis, were included in the study. We tested these patients for HCV RNA in peripheral blood mononuclear cells (PBMCs) immediately after confirmation of SVR12-24 weeks. Statistical analysis was performed by means of the Shapiro-Wilk test, Mann-Whitney U test, Chi-square test, and Fisher's exact test. Seventeen patients (11.33%) were positive for PBMNCs HCV RNA. The prevalence of OCI was highest in patients treated with simeprevir/sofosbuvir (2/2 patients). There is a substantially high prevalence of OCI after treatment with DAAs. We recommend dual testing for HCV RNA in both serum and PBMCs at the end of treatment of HCV infection with DAAs and during validation of the SVR following the initial response.

Abstract
OBJECTIVE To provide an accessible source of clinical information related to the diagnosis and treatment of psychiatric morbidity associated with HIV infection. METHOD A selective MEDLINE literature search was used to identify 225 relevant articles, 67 of which were selected for inclusion based upon the presence of psychiatric morbidity. Psychiatric morbidity was defined by the presence of a DSM-IV diagnostic code reflecting psychiatric illness. RESULTS HIV-infected patients have high rates of psychiatric morbidity. CONCLUSION The psychiatric evaluation and treatment of psychiatric morbidity improve the quality of life of HIV and AIDS patients.
