  Introduction: Focal Segmental Glomerulosclerosis (FSGS) corresponds to a clinicopathological syndrome, manifested by generally abundant proteinuria associated with hyaline deposits on part of certain glomeruli and sparing other glomeruli, with effacement of the pedicels. The general objective was to determine the prevalence of FSGS, and to give its profiles; epidemiological, clinical, biological, pathological, etiological, therapeutic and evolutionary of FSGS. 
  Materials and Methods: This is a retrospective analytical study over a period of six years extending from January 1, 2010 to December 31, 2015 patients aged 16 or over who were hospitalized or received consultations during the study period for primary or secondary segmental and focal hyalinosis. Patients whose records were incomplete or unusable were not included in the study. 
  Results: We have 16.54% with 158 cases of FSGS out of 6945 patients received and/or hospitalized. Of the 955 kidney biopsies distributed, the incidences of HSF were; 10.15%; 14.04%; 15%; 17.64%; 20.11%; 19.58% respectively in 2010; 2011; 2012; 2013; 2014 and 2015, 
  i.e. an annual increase of around 1.25%. Renal-type edemas were found in 93.3%, the first reason for hospitalization. And ninety-six people had impaired kidney function, or 61%. The average of 24-hour proteinuria was 6.4 &#177; 3.69 g/24 hours. The extremes were 0.37 and 18.50 g/24h. Patients had nephrotic proteinuria in 84.86%. Non-specific FSGS or NOS (Not Other Specificities) was found in 62 cases or 39.24%, collapsing FSGS in 48 cases or 30.40%. FSGS with found causes was associated with fibrosis in 5/35 cases. Collapsing FSGSs followed by NOS FSGSs were the most corticosteroid-resistant. The evolution of the FSGS reveals that every 8 months the proteinuria decreases by half. 
  Conclusion: Segmental and focal hyalinosis requires histological confirmation and the epidemiological, clinico-biological, etiological, therapeutic and evolutionary profiles depend on the histological (pathological) type. Other works on the risk factors for occurrence and the contribution of electron microscopy in the primary and secondary diagnosis of segmental and focal hyalinosis are desired.

Introduction</title><p>Focal Segmental Glomerulosclerosis (FSGS) type glomerulonephritis corresponds to a clinicopathologic syndrome, and is characterized by generally abundant proteinuria associated with hyaline deposits on part of certain glomeruli and sparing other glomeruli, with effacement of the pedicels. Hyaline, defined as a smooth glassy material, results from glomerular infiltration of plasma proteins [<xref ref-type="bibr" rid="scirp.126140-ref1">1</xref>] [<xref ref-type="bibr" rid="scirp.126140-ref2">2</xref>] [<xref ref-type="bibr" rid="scirp.126140-ref3">3</xref>] . The Columbia classification describes five variants or classes of FSGS: the FSGS of the urinary pole (tip lesion), the collapsing form, the cellular form, the perihilar or vascular form and the form with hypercellularity. FSGS is usually steroid-dependent or resistant, it is responsible for renal failure in most cases [<xref ref-type="bibr" rid="scirp.126140-ref1">1</xref>] [<xref ref-type="bibr" rid="scirp.126140-ref2">2</xref>] [<xref ref-type="bibr" rid="scirp.126140-ref3">3</xref>] .</p><p>The diagnosis of clinically evoked FSGS requires histological confirmation, and it can be primary or secondary [<xref ref-type="bibr" rid="scirp.126140-ref1">1</xref>] [<xref ref-type="bibr" rid="scirp.126140-ref2">2</xref>] [<xref ref-type="bibr" rid="scirp.126140-ref3">3</xref>] .</p><p>Segmental and focal hyalinosis is the first glomerular lesion in Africans [<xref ref-type="bibr" rid="scirp.126140-ref4">4</xref>] [<xref ref-type="bibr" rid="scirp.126140-ref5">5</xref>] .</p><p>The clinical and biological complications are similar to those of the nephrotic syndrome.</p><p>The prevalence of FSGS was 52% in a series of renal biopsies over a period from 1993 to 2001 in Dakar [<xref ref-type="bibr" rid="scirp.126140-ref5">5</xref>] .

The work of Dial et al. [<xref ref-type="bibr" rid="scirp.126140-ref5">5</xref>] had found 29.7% complete remission for the primary forms.

The repeated administrations of retuximab were not associated with an habituation effect and resulted in a high percentage of complete or partial remission comparable to larger pediatric studies. Renal function remained stable during the treatment period. This approach led to an extension of relapse-free survival compared to previous treatment regimens over a median duration of follow-up of 110 months. And the translational study has identified clopidogrel as a promising therapeutic option for FSGS via network-based bioinformatics analysis. Clopidogrel significantly improved key outcome parameters in the adriamycin FSGS mouse model, including albuminuria, weight loss, and histopathological lesions of the kidney. These data, along with a favorable drug safety profile, endorse clopidogrel as an attractive candidate for drug repositioning and subsequent clinical trial evaluation for patients suffering from FSGS [<xref ref-type="bibr" rid="scirp.126140-ref20">20</xref>] [<xref ref-type="bibr" rid="scirp.126140-ref21">21</xref>] [<xref ref-type="bibr" rid="scirp.126140-ref22">22</xref>] .</p></sec></sec></sec><sec id="s5"><title>5.
