Input: Twelve studies conducted in China, including 762 children with nephrotic syndrome were identified. No studies were identified in adults. All studies compared one kind of prophylactic pharmacotherapy (intravenous immunoglobulin (IVIG), thymosin, oral transfer factor, mannan peptide tablet, Bacillus Calmette-Guerin (BCG) vaccine injection, polyvalent bacterial vaccine (Lantigen B) and two kinds of Chinese medicinal herbs: a compound of Chinese medicinal herbs (TIAOJINING) and Huangqi (astragalus) granules) plus baseline treatment with baseline treatment alone. No RCTs were identified comparing antibiotics, non-pharmacological prophylaxis, or pneumococcal vaccination. Four studies showed a significantly beneficial effect of IVIG on preventing nosocomial or unspecified infection in children with nephrotic syndrome (RR 0.47, 95% CI 0.31 to 0.73). Thymosin (RR 0.50, 95% CI 0.26 to 0.97), oral transfer factor (RR 0.51, 95% CI 0.35 to 0.73), BCG vaccine injection (RR 0.68, 95% CI 0.48 to 0.95), Huangqi granules (RR 0.62, 95% CI 0.47 to 0.83) and TIAOJINING (RR 0.59, 95% CI 0.43 to 0.81) were also effective in reducing the risk of infection in children with nephrotic syndrome. However mannan peptide tablet (RR 0.46, 95% CI 0.21 to 1.01) and polyvalent bacterial vaccine (RR 0.24, 95% CI 0.06 to1.00) were not superior to baseline treatment in reducing the risk of infection for nephrotic children. No serious adverse events were reported. IVIG, thymosin, oral transfer factor, BCG vaccine, Huangqi granules and TIAOJINING may have positive effects on the prevention of nosocomial or unspecified infection with no obvious serious adverse events in children with nephrotic syndrome. However the methodological quality of all studies was poor, the sample sizes small, and all studies were from China, and thus there is no strong evidence on the effectiveness of these interventions.
Output:

No studies on antibiotics, pneumococcal vaccination and any other non-drug prophylaxis were identified. This review found that intravenous immunoglobulin (IVIG), thymosin, oral transfer factor, Bacillus Calmette-Guerin (BCG) vaccine injection and two kinds of Chinese medicinal herbs (Huangqi granules and TIAOJINING) may help prevent infections in nephrotic children. These studies were methodologically poor. Currently there is no strong evidence for recommending any interventions for preventing infections in nephrotic syndrome. More research is needed.
