Resolution of syphilis-related rapidly progressive glomerulonephritis with penicillin therapy: Case report 
.

We report a rare case of RPGN secondary to latent syphilis, which resolved with penicillin treatment in the absence of immunosuppressive therapy. A 28-year-old Black male with a history of HIV was evaluated for severe acute kidney injury, nephrotic-range proteinuria, and active urine sediment. Serologies for glomerulonephritis were negative. Rapid plasma reagin and treponema pallidum particle agglutination assay were reactive, confirming syphilis diagnosis. Kidney biopsy revealed focal and segmental necrotizing and crescentic lesion. Patient received weekly benzathine penicillin (PCN) for 3 weeks, and renal function improved to baseline. This dramatic improvement happened with PCN alone, a finding which has not been previously reported. We recommend that syphilis be considered in the differential diagnosis of all patients with proteinuria or suspected glomerulonephritis.

Publication date: Available online 24 January 2020Source: Carbohydrate PolymersAuthor(s): Hongbo Suo, Lili Xu, Yu Xue, Xiang Qiu, He Huang, Yi HuAbstractIn this work, ionic liquids-modified magnetic carboxymethyl cellulose nanoparticles (IL-MCMC) were prepared and used as supports for enzyme immobilization. The specific activity of immobilized lipase PPL-IL-MCMC was 1.43 and 2.81 folds higher than that of free PPL and PPL-MCMC, respectively. Water contact angle analysis indicated that the introduction of ionic liquids increased the hydrophobicity of supports, which in tune induced the lid-opening of lipase, allowing its ac...

This study was conducted to find the association of baseline blood pressure (BP) with pathophysiologic findings and later renal progression in chronic GN. Methods: Clinico-pathological findings including serum creatinine (Cr), proteinuria, pathological findings, and urinary Na excretion were analyzed in a total of 233 patients with IgA nephropathy from The Kyung-Hee Cohort of GN. Glomerular surface area (GSA) was measured by imaging analysis and urine angiotensinogen (AGT) concentrations by human ELISA kits. Results: Systolic BP was ≥130mmHg in 124 patients (53%). Systolic BP was negatively correlated with follo...

Conclusion: The SBP at 7:00 AM, in addition to the 24-hour mSBP, is also associated with eGFR deterioration in patients with diabetic CKD, particularly in those with CKD stage 3-5. PMID: 31969922 [PubMed]

Conclusion: In this study, we found that RAS blockade was significantly associated with a reduction in mortality but not in the incidence of ESRD. However, 26.3% of the enrolled patients did not use RAS blockade. Physicians need to consider the usefulness of RAS blockade in hypertensive patients with proteinuria. PMID: 31969921 [PubMed]

This study evaluates whether MIF can regulate integrin-β1/cyclin D1 expression and cell adhesion of podocytes.Main methodsExpression of integrin-β1 mRNA/protein and cyclin D1 mRNA under stimulation of MIF was evaluated by real-time PCR and Western blotting. MIF receptor (CD74) and MAP kinase under MIF treatment were examined to determine which pathway regulated integrin-β1 and cyclin D1 expression. Cell adhesion was evaluated under MIF treatment and/or anti-integrin-β1 antibody by cell adhesion assay.Key findingsProtein levels of integrin-β1 were up-regulated under MIF treatment in a dosage-depende...

We describe a case of aggressive progression of TA in an infant. This child was the youngest to be affected with the disease as reported in the literature. A 3.5-month-old boy presented with cyanosis of both legs, tachycardia and antithrombin III deficiency. Computed tomography angiography (CTA) revealed thrombosis of distal aorta and both iliac arteries. Thrombectomy was performed at the level of both common femoral arteries. In addition, thigh amputation of the left leg had to be performed. TA was diagnosed postmortem with thrombosis of the distal aorta, its branches and upper mesenteric artery which was not occluded on ...

CONCLUSION: In Chinese hypertensive patients, increased BMI and increased WC were individually and jointly associated with a higher risk of new-onset proteinuria, underscoring the value of monitoring both BMI and waist circumference in assessing proteinuria risk.
