Abstract

The Columbia working classification of focal segmental glomerulosclerosis (FSGS) identifies five types of glomerular lesions, designated collapsing (COLL), cellular (CELL), glomerular tip lesion (GTL), perihilar (PH), and not otherwise specified (NOS) variant lesions. FSGS COLL and non-collapsing variants of FSGS are described in human immunodeficiency virus (HIV)-associated kidney disease. This study examined the range and relationships of Columbia-type segmental sclerosing lesions in biopsies from patients with HIV infection. We identified 47 renal biopsies from 46 patients with HIV infection obtained over an 8-year period. Twenty-seven biopsies from 26 patients had FSGS. Sixteen biopsies had FSGS COLL (59.3%), 3 had CELL (11.1%), 5 had NOS (18.5%), 2 had PH (7.4%), and 1 had GTL (3.7%) by the Columbia classification. Biopsies had more than one type of Columbia FSGS lesion in 63% and one type in 37%. Single types of FSGS lesions were identified in eight of eight biopsies with ≤10 glomeruli. Combinations of lesions were observed in 17 of 19 (89.5%) with >10 glomeruli, and the coincidence of COLL, CELL, and NOS lesions was not random. NOS, COLL, and CELL morphologic lesions of FSGS frequently coexist in kidney biopsies from HIV+ patients. Combined patterns of FSGS suggest that lesions identified by Columbia criteria may be part of a spectrum of responses to injury in the setting of HIV infection.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 18 March 2012.
All research outputs
#5,480,674
of 7,598,764 outputs
Outputs from Virchows Archiv
#346
of 639 outputs
Outputs of similar age
#54,707
of 91,636 outputs
Outputs of similar age from Virchows Archiv
#3
of 24 outputs
Altmetric has tracked 7,598,764 research outputs across all sources so far. This one is in the 24th percentile – i.e., 24% of other outputs scored the same or lower than it.
So far Altmetric has tracked 639 research outputs from this source. They receive a mean Attention Score of 2.4. This one is in the 36th percentile – i.e., 36% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 91,636 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 36th percentile – i.e., 36% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 24 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 83% of its contemporaries.
