RESUMO

PURPOSE OF THE STUDY: The current study aimed to detect the frequency of normal and mutated APOL1 alleles in sickle cell disease (SCD) patients and test their relation with Microalbuminuria, Creatinine, Urea, Glomerular Filtration Rate (GFR), and Body Mass Index (BMI). PATIENTS AND METHODS: The study included 156 SCD subjects. Serum Creatinine (mg/dl) and Urea (mg/dl) as well as Microalbuminuria (mg/l) level were measured by using Biosystems kit (Biosystems, Barcelona, Spain) and Mindary BA88A semi-automated biochemistry analyzer. Glomerular filtration rate and body mass index were calculated by equations. Blood DNA extraction was achieved by using the modified G-DEX™IIb Genomic DNA Extraction Kit protocol. The PCR was done for the detection of the APOL1 G2 rs60910145 alleles by using allele-specific PCR and primers. RESULTS: The CC allele was more frequent in study cases (66.7%) than TT allele. The frequency of a mutated allele (CC) was insignificantly higher in males (67.8%) than in females (65.2%) and in rural (70.9%) than urban areas. It is also higher in Shankhab compared to other tribes and subjects 26-37 years compared to other, P˃0.05. Interstingly, the subjects who carry the CC allele showed a significantly higher level of Microalbuminuria, Creatinine, BMI, and Urea compared to those carry TT allele. Moreover, GFR is also higher in subjects who carry CC than TT allele but it is not significant. CONCULSION: Altogether, the study findings highlighted the link of normal and mutated APOL1 G2 rs60910145 alleles with SCD and displayed the significant value of mutated APOL1 allele in the prediction of early nephropathy in SCD patients.

RESUMO

Globally, tuberculosis is one of the major causes of morbidity and mortality in many countries. Previous studies suggest that the incidence and severity of tuberculosis are associated with low levels of vitamin D (Vit D). Therefore, this study aimed to determine the occurrence and associated factors of vitamin D3 deficiency in pulmonary tuberculosis patients at White Nile State, Sudan. 101 individuals of diagnosed pulmonary tuberculosis patients (71 males and 30 females) and 100 non-TB controls (58 males and 42 females) were included in this study. Sputum samples were obtained from TB patients and subjected to examination for acid-fast bacilli (AFB) using Ziehl-Neelsen (ZN) stain and Gene Xpert analysis. Blood samples were collected from both groups and Serum 25(OH)-vitamin D3 was determined by an Enzyme-Linked Immunosorbent Assay. HIV infection in Tuberculosis (TB) group was also investigated using the immunochromatographic test. In our study, the majority of TB patients were suffered from TB relapse (36.6%); non-HIV infected individuals (99.1%) or showed a positive result for AFB (61.4%) in Gene Xpert analysis. Moreover, there is a significant difference in microscopy findings and bacillary levels of AFB, and Rifampicin (RIF) susceptibility pattern of M. tuberculosis strain among sputum samples of TB patients, P-values less 0.0001. Furthermore, we found that TB patients were suffered from vitamin D deficiency. In particular, the mean of vitamin D level was significantly much lower in TB patients (26.7 ± 1.6) compared to non-TB controls (117.3 ± 3.2), P-value equal 0.0001. Likewise, it's much lower in females, individuals of 21-40 years old, and patients with high bacillary levels or those infected by Rifampicin resistance strain. Accordingly, our study was highlighted the TB and Vit D deficiency relationship and showed the need for further studies to a better understanding of the impact of TB on Vit D level and investigate whether vitamin D supplementation can have a role in the prevention and treatment of tuberculosis.
