The damage is non-specific, and several different causes have been described. As such, it is essential to distinguish between idiopathic and secondary forms of the disease (Table 1), since their pathogenesis, prognosis, and treatment are very different.<span class="elsevierStyleSup">1</span></p><p class="elsevierStylePara">Fortunately, FSGS is an uncommon disease that is found only in 9% of all kidney biopsies in our country, with stable rates in recent years. However, it is the third-leading cause of nephrotic syndrome, preceded only by membranous nephropathy and minimal change nephropathy.<span class="elsevierStyleSup">2</span> Here, we will only be referring to idiopathic FSGS that presents with nephrotic syndrome, since this is a major challenge for the attending physician given the knowledge gaps regarding its pathogenesis. As with other glomerular diseases, its treatment must be based on the best evidence available through controlled clinical trials. However, few studies have been performed to resolve the current problems with treatment, and many of them are of poor quality, as reported by Quereda and Ballarín in an excellent systematic review published in <span class="elsevierStyleItalic">Nefrología</span> in 2007.<span class="elsevierStyleSup">3</span> Their conclusions have not lost their relevance and coincide with the recommendations soon to be published in the KDIGO guidelines for the treatment of glomerulonephritis. FSGS is no exception to this rule of low number and quality of clinical trials studying glomerular diseases, with even lower representation than lupus nephritis and membranous nephropathy.<span class="elsevierStyleSup">4</span></p><p class="elsevierStylePara"> </p><p class="elsevierStylePara"><span class="elsevierStyleBold">INITIAL TREATMENT</span></p><p class="elsevierStylePara">Patients with idiopathic FSGS that do not develop a nephrotic syndrome, as well as those with secondary FSGS, do not receive immunosuppressive treatment (recommendation 1C, GRADE system). In these cases, the standard treatment consists of: <span class="elsevierStyleItalic">1)</span> maintain blood pressure below 130/80mm Hg; <span class="elsevierStyleItalic">2)</span> administer angiotensin-converting enzyme (ACE) inhibitors, angiotensin II receptor antagonists, or both; <span class="elsevierStyleItalic">3)</span> administer statins; <span class="elsevierStyleItalic">4)</span> administer antiplatelet or anticoagulation therapy; and <span class="elsevierStyleItalic">5)</span> diet for renal protection.<span class="elsevierStyleSup">5</span> The initial treatment is based on a prednisone cycle (1mg/kg/day, maximum of 80mg/day or 2mg/kg/day on alternate days, maximum of 120 mg), which should be maintained for 16 weeks before the condition is declared corticosteroid-resistant.<span class="elsevierStyleSup">6</span> Treatment with prednisone can cause remission of the disease in 60%-70% of patients, according to the studies. These responses depend on the intensity of the initial proteinuria, the tubular/interstitial lesions, and the baseline creatinine level, although it is not possible <span class="elsevierStyleItalic">a priori </span>to separate the patients that will respond to corticosteroid treatment from those that will not. As a rule, this should not be combined with treatment using other immunosuppressive drugs, unless there is a risk of toxicity or intolerance to steroids (obesity, osteoporosis, diabetes, advanced age, or psychiatric imbalances). If they were to be used, calcineurin inhibitors are recommended (suggestion 2D), as will be indicated later when discussing corticosteroid-resistant forms of the disease.<span class="elsevierStyleSup">3 </span>Partial or complete remission of proteinuria has been associated with a good prognosis, and it is the most indicative marker of patient evolution, even more than clinical and histological results.<span class="elsevierStyleSup">7</span> Approximately 30%-40% of patients are corticosteroid-resistant, presenting problems for developing a treatment plan, since resistance to corticosteroids is the strongest predictor for the development of chronic kidney disease: 35% at 5 years and 70% at 10 years. As such, the current conundrum is: how can we treat idiopathic FSGS that has not responded to steroids or is corticosteroid-dependent? Can we modify the patient evolution towards kidney failure? Here, we will go through the different treatments recommended in corticosteroid-resistant FSGS according to the evidence published on the subject (Table 2). Obviously, each case should be analysed individually, and treated according to the personal opinion and experience of the physicians that directly attend to each patient.</p><p class="elsevierStylePara"> </p><p class="elsevierStylePara"><span class="elsevierStyleBold">CALCINEURIN INHIBITORS</span></p><p class="elsevierStylePara">Cyclosporin A (CsA) is the best documented method of treatment in controlled trials and observational studies.<span class="elsevierStyleSup">3,8</span> The recommended dose is 2-5mg/kg/day administered in two doses (with levels of 125-175ng/ml) during a minimum of 6 months. If at the end of this time there is no response, treatment must be suspended and the patient should be considered resistant to CsA. In the case of a partial or complete response, which appears in 60%-70% of cases,<span class="elsevierStyleSup">9,10</span> treatment should be maintained for at least 12 months, and can then be progressively reduced by 25% every 2 months. Approximately half of all patients that initially respond to CsA develop resistance eventually. Fewer studies exist regarding the use of tacrolimus in the treatment of corticosteroid-resistant FSGS, but Segarra et al<span class="elsevierStyleSup">11</span> obtained positive results from using tacrolimus (0.15mg/kg/day; levels of 5-10ng/l) and low-dose steroids (0.15mg/kg/day) in 25 patients with previous resistance to steroids and CsA. Therefore, its use in patients that have not responded to CsA is an attractive treatment option that deserves a try before moving on to other alternatives. Even so, treatment with calcineurin inhibitors creates other problems: nephrotoxicity and recurrence after treatment suspension. The first condition can be avoided by using the minimum possible dose, monitoring patient levels, and by performing a kidney biopsy in order to evaluate vascular and interstitial damage. Recurrence is very common after reducing the dosage or suspending treatment with this drug, reaching even 70% in some studies. A study, sponsored by the GLOSEN (glomerulonephritis study group of the Spanish Society of Nephrology), has been recently performed on 5 patients, who were administered calcineurin inhibitors as an induction therapy, followed by rituximab once remission was established, with no positive results in avoiding recurrence after treatment suspension.<span class="elsevierStyleSup">12</span> Recurrence is still an unresolved problem that requires more in-depth<span class="elsevierStyleBold"> </span>studies. On the other hand, given that approximately 30% of cases do not respond to calcineurin inhibitors, other treatments have also been tested.</p><p class="elsevierStylePara"> </p><p class="elsevierStylePara"><span class="elsevierStyleBold">MYCOPHENOLATE MOFETIL</span></p><p class="elsevierStylePara">Experience with this drug is scarce,<span class="elsevierStyleSup">6</span> with an approximately 44% of cases showing a partial response, but half of these patients suffer a recurrence when medication is suspended.<span class="elsevierStyleSup">7</span> This is an option when other immunosuppressive drugs cannot be administered, or when steroid dosage must be decreased (suggestion 2C).</p><p class="elsevierStylePara"> </p><p class="elsevierStylePara"><span class="elsevierStyleBold">RITUXIMAB</span></p><p class="elsevierStylePara">In a recent study that was also sponsored by GLOSEN,<span class="elsevierStyleSup">13</span> involving 8 patients with FSGS resistant to other drug treatments, rituximab had a positive effect in only 3 cases, making it an unattractive alternative, at least as a monotherapy. Therefore, controlled studies are needed,<span class="elsevierStyleSup">8</span> but it still can provide an alternative when nephrotoxicity develops due to the administration of calcineurin inhibitors.<span class="elsevierStyleSup">14</span></p><p class="elsevierStylePara"> </p><p class="elsevierStylePara"><span class="elsevierStyleBold">ALKYLATING AGENTS</span></p><p class="elsevierStylePara">Some experience has been gained in the administration of cyclophosphamide and chlorambucil, as they were used before the advent of calcineurin inhibitors. However, they only produce a complete response in 20% of cases, and a partial response in 45%. These results, along with the adverse effects (infections, tumours, leukopenia, infertility), have severely reduced the role of these drugs,<span class="elsevierStyleSup">9</span> with insufficient evidence to support their use.<span class="elsevierStyleSup">6,15,16</span></p><p class="elsevierStylePara"> </p><p class="elsevierStylePara"><span class="elsevierStyleBold">COMBINED TREATMENTS</span></p><p class="elsevierStylePara">Given the limitations presented by the previous drug treatments, some authors have incorporated the concept of synergistic effects of immunosuppressive drugs (taken from the experience gained in transplantations) into the treatment of glomerular diseases. In this issue of <span class="elsevierStyleItalic">Nefrología</span>, Segarra et al<span class="elsevierStyleSup">17</span> have published on their experience in treating primary FSGS in 27 adult patients with previously failed treatment plans using steroids and CsA, combining CsA (4mg/kg/day) with mycophenolate mofetil (2000mg/day) for 12 months. This was an observational study with no controls, and it produced disappointing results. None of the patients in this study reached complete remission of the disease, and only one fourth partial remission. Additionally, the glomerular filtration rate was significantly reduced in all patients, and 59% of cases developed uraemia at the end of the 5-year follow-up period, which is a similar result to that achieved by treating patients symptomatically. Lastly, the authors used a multivariate analysis to show that initial glomerular filtration rates and mean proteinuria during the follow-up period were correlated with renal impairment. El-Reshaid et al<span class="elsevierStyleSup">18</span> had already tested a similar combined treatment, with somewhat better results, but in patients without previous failure of CsA treatment. The role that this three-part association may play in the treatment of idiopathic FSGS resistant to steroids and CsA is still unclear. Although the authors did not perform a genetic analysis, it is quite probable that the hereditary forms of the disease were not present in the study, since the necessary genetic mutations (NPHS1, NPHS2, alpha-actinin-4, CD2P, TRPC-6 and others) are very rare in adults.<span class="elsevierStyleSup">19</span> With these results, the triple therapy using steroids, CsA, and mycophenolate mofetil appears not to decrease proteinuria or slow the development of kidney disease.</p><p class="elsevierStylePara">Although the treatment of corticosteroid-resistant idiopathic FSGS is still an unresolved issue, we must not be pessimistic. Several different clinical trials have been initiated<span class="elsevierStyleSup">20,21</span> that may help to improve the current results. As the KDIGO guidelines will state, more controlled clinical trials are needed to compare the efficacy of calcineurin inhibitors, mycophenolate mofetil, rituximab, and alkylating agents in treating corticosteroid-resistant FSGS. Lastly, we must re-evaluate the use of our current arsenal of immunosuppressive drugs, whose mechanisms of action are still unknown and are mostly empirical.<span class="elsevierStyleSup">22</span> According to a recent review by Meyrier,<span class="elsevierStyleSup">23</span> the factor or factors that lead to an increase in capillary permeability must be identified in order to treat these patients accordingly.</p><p class="elsevierStylePara">In conclusion, the treatment of idiopathic FSGS patients with nephrotic syndrome is still unresolved, and clinicians are faced with a challenge in producing some type of response in the patient and slowing or halting the evolution towards kidney failure. In spite of the negative results obtained by the excellent study by Segarra et al,<span class="elsevierStyleSup">17</span> which inspired this “Editorial Comment,” we must continue to research ways to improve the current unsatisfactory results.</p><p class="elsevierStylePara"><span class="elsevierStyleBold"> </span></p><p class="elsevierStylePara"><span class="elsevierStyleBold">KEY CONCEPTS</span></p><p class="elsevierStylePara">1.
