Association of High Density Lipoprotein Cholesterol with Renal Function in Type 2 Diabetic Subjects in a Bangladeshi Population

Background: Abnormalities in lipid metabolism are associated with renal diseases. Association of serum lipid parameters with renal function is less studied in subjects with type 2 diabetes in Bangladeshi population. Objective: To assess the correlation of high density lipoprotein cholesterol with glomerular filtration rate (GFR) in type 2 diabetic subjects. Materials and Methods: One thousand three hundred thirty confirmed diabetic subjects advised for HbA1c, serum creatinine, serum total cholesterol, serum triglycerides, serum HDL cholesterol and LDL cholesterol were included in the study. Serum total cholesterol, HDL cholesterol, triglyceride, serum creatinine, HbA1c were measured by standard methods and serum LDL cholesterol was calculated by Friedewald’s formula. GFR was calculated by MDRD4 variables prediction equation. Total subjects were grouped according to sex; both males and females were subdivided into three subgroups depending on GFR values. Results of lipid parameters were compared by one-way ANOVA among different groups and correlation of lipid parameters with GFR were expressed by Pearson r. Results: HDL cholesterol was significantly different among different GFR groups (p<0.05) and positively correlated with GFR (r = 0.1386, p<0.001) in males. Total cholesterol and LDL cholesterol showed feeble positive correlation with GFR (r = 0.0789, p<0.05 for total cholesterol and r = 0.0768, p<0.05 for LDL cholesterol), but are not significantly different among GFR groups (p>0.05) in males. Total cholesterol, HDL cholesterol, LDL cholesterol, non-HDL cholesterol and LDLC/HDL-C were significantly different among three different GFR groups (p<0.01) and only HDL cholesterol and LDL-C/HDL-C showed weak correlation with GFR (r = 0.0770, p<0.05 for HDL cholesterol and r = -0.0803, p<0.05 for LDL-C/HDL-C) in females. Conclusion: The study revealed that HDL cholesterol was significantly and positively correlated with glomerular filtration rate in both male and female diabetic subjects and assessment of lipid parameters might be a helpful tool to prevent or delay the progression of renal insufficiency

Draft genome sequences of three strains of campylobacter jejuni isolated from patients with guillain-barré syndrome in bangladesh

Campylobacter jejuni is the pathogen most commonly associated with Guillain-Barré syndrome (GBS). The present work describes the draft genome sequences of 3 C. jejuni strains, BD39, BD67, and BD75, isolated from stool specimens of patients with C. jejuni-triggered GBS using Illumina technologies

Guillain-Barr ' e syndrome associated with SARS-CoV-2 infection: A case report with long term follow up: A case report with long term follow up

A 50-years old male presented with quadriplegia and paresthesia and was diagnosed as Guillain-Barré syndrome (GBS). He was found positive for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) six weeks prior to the onset of weakness. GBS disability score was 4. Electrophysiology showed acute inflammatory demyelinating polyradiculopathy. Anti-SARS-CoV-2 IgG was found positive. Immunological tests for Campylobacter jejuni, Zika virus, Hepatitis E virus, Herpes Simplex virus, Haemophilus influanzae and Mycoplasma pneumoniae were negative. Patient received standard dose of intravenous immunoglobulin and after six months had almost complete recovery of muscle power. This case represents possible association of SARS-CoV-2 infection and GBS with good clinical outcome

Association of mannose-binding lectin 2 gene polymorphisms with Guillain-Barré syndrome

Complement activation plays a critical role in the pathogenesis of Guillain-Barré syndrome (GBS), a debilitating immune-mediated neuropathy. Mannose-binding lectin (MBL) is a complement activation factor of lectin pathway which as genetic host factor may influence the susceptibility or severity of GBS. We investigated the frequency of MBL2 promoter (− 550H/L and − 221X/Y) and functional region (exon 1 A/O) polymorphisms and their association with disease susceptibility, clinical features and serum MBL among GBS patients (n = 300) and healthy controls (n = 300) in Bangladesh. The median patient age was 30 years (IQR: 18–42; males, 68%). MBL2 polymorphisms were not significantly associated with GBS susceptibility compared to healthy controls. HL heterozygosity in GBS patients was significantly associated with mild functional disability at enrolment (P = 0.0145, OR, 95% CI 2.1, 1.17–3.82). The HY, YA, HA and HYA heterozygous haplotypes were more common among mildly affected (P = 0.0067, P = 0.0086, P = 0.0075, P = 0.0032, respectively) than severely affected patients with GBS. Reduced serum MBL was significantly associated with the LL, OO and no HYA variants and GBS disease severity. No significant association was observed between MBL2 polymorphisms and electrophysiological variants, recent Campylobacter jejuni infection or anti-ganglioside (GM1) antibody responses in GBS. In conclusion, MBL2 gene polymorphisms are related to reduced serum MBL and associated with the severity of GBS
