Chinese Journal of Contemporary Pediatrics 2014;16(4):397-400
OBJECTIVETo investigate the efficacy of letrozole for delaying bone maturation and increasing predicted adult height in boys with idiopathic central precocious puberty (ICPP) who have a bone age above 13 years and a short stature, and its adverse effects.
METHODSTwenty ICPP boys with a bone age above 13 years and a short stature were randomly divided into letrozole treatment (n=10) and control groups (n=10). The letrozole treatment group received oral letrozole [2.5 mg/(m(2)·d), Qd] for 6 months, while the control group received no treatment and was observed periodically. Bone age, growth rate, height standard deviation (SD) score, predicted adult height SD score, sexual maturity, and levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), dehydroepiandrosterone, testosterone (T), estradiol (E2), progesterone (P), and androstenedione (ASD) were measured. The letrozole-related adverse reactions were evaluated.
RESULTSAfter 6 months of treatment, both groups had a significantly increased bone age, but the letrozole group had a significantly slowed increase in bone age compared with the control group (13.82 ± 0.23 years vs 14.47 ± 0.30 years; P<0.05); compared with the control group, the letrozole group had a significantly increased predicted adult height SD score (-1.69 ± 0.26 vs -1.91 ± 0.35; P<0.05) and a significantly increased T level (4.9 ± 0.9 nmol/L vs 4.4 ± 0.8 nmol/L; P<0.05). There was no significant difference in testicular volume between the two groups. The treatment led to no significant changes in growth rate, Tanner stage, and levels of FSH, LH, P, E2 and ASD in the two groups, and there was no significant difference in these indices between the two groups. No adverse reactions were observed during letrozole treatment.
CONCLUSIONSLetrozole delays bone maturation and increases predicted adult height in ICPP boys with a bone age above 13 years and a short stature, and it causes no obvious adverse reactions.

PURPOSE: Posaconazole is a second-generation triazole with a broad spectrum. However, there is a lack of data to support a significant role for posaconazole in the treatment of invasive fungal infection (IFI), especially in Korea. Until recently, posaconazole was available only through the Korean Orphan Drug Center. This study was designed to review the use of posaconazole at a single-center in Korea. MATERIALS AND METHODS: Data from patients who received posaconazole treatment at Catholic Blood and Marrow Transplantation Center were retrospectively reviewed between January 2007 and September 2012. RESULTS: A total of 11 cases (3 males and 8 females, median age 52 years) received posaconazole. Five patients were given the drug for mucormycosis, two for invasive aspergillosis, and four for unspecified IFI for which galactomannan (GM) assays were negative. The treatment duration ranged from 4-250 days. Three patients received posaconazole for management refractory IFI, two for intolerance of previous antifungal therapy, and six for long-term maintenance treatment. The overall successful response rate to posaconazole was 55% (six of eleven patients). Five of eleven patients died during the study period. However, only one death was attributed to the progression of IFI. None of the patients discontinued posaconazole therapy due to adverse events. CONCLUSION: Posaconazole is an attractive oral antifungal agent for salvage treatment of IFI, particularly upon diagnosis of mucormycosis or in cases in which mucormycosis cannot be ruled out due to a negative GM.

Objective:
This research was performed to evaluate the effect of tebuconazole (TBZ) on reproductive organs of male rats and to assess the protective role of combined essential trace elements in alleviating the detrimental effect of TBZ on male reproductive function.
Methods:
For this purpose, 48 rats were exposed to 100 mg/kg TBZ, TBZ supplemented with zinc (Zn), selenium (Se), copper (Cu), and iron (Fe), TBZ + (Se + Zn); TBZ + Cu; or TBZ + Fe. The experiment was conducted for 30 consecutive days.
Results:
TBZ caused a significant perturbation in mineral levels and reduction in reproductive organs weights, plasma testosterone level, and testicular antioxidant enzyme activities. The TBZ-treated group also showed a significant increase in sperm abnormalities (count, motility, and viability percent), plasma follicle-stimulating hormone and luteinizing hormone concentrations, lipid peroxidation, protein oxidation, and severe DNA degradation in comparison with the controls. Histopathologically, TBZ caused testis impairments. Conversely, treatment with trace elements, in combination or alone, improved the reproductive organ weights, sperm characteristics, TBZ-induced toxicity, and histopathological modifications in testis.
Conclusion
TBZ exerts significant harmful effects on male reproductive system. The concurrent administration of trace elements reduces testis dysfunction, fertility, and toxicity induced by TBZ.

OBJECTIVE:
To evaluate the synergy of the Burkholderia signaling molecule cis-2-dodecenoic acid (BDSF) and fluconazole (FLU) or itraconazole (ITRA) against two azole-resistant C. albicans clinical isolates in vitro and in vivo.
METHODS:
Minimum inhibitory concentrations (MICs) of antibiotics against two azole-resistant C. albicans were measured by the checkerboard technique, E-test, and time-kill assay. In vivo antifungal synergy testing was performed on mice. Analysis of the relative gene expression levels of the strains was conducted by quantitative reverse-transcription polymerase chain reaction (qRT-PCR).
RESULTS:
BDSF showed highly synergistic effects in combination with FLU or ITRA with a fractional inhibitory concentration index of ⪕ 0.08. BDSF was not cytotoxic to normal human foreskin fibroblast cells at concentrations of up to 300 μg/mL. The qRT-PCR results showed that the combination of BDSF and FLU/ITRA significantly inhibits the expression of the efflux pump genes CDR1 and MDR1 via suppression of the transcription factors TAC1 and MRR1, respectively, when compared with FLU or ITRA alone. No dramatic difference in the mRNA expression levels of ERG1, ERG11, and UPC2 was found, which indicates that the drug combinations do not significantly interfere with UPC2-mediated ergosterol levels. In vivo experiments revealed that combination therapy can be an effective therapeutic approach to treat candidiasis.
CONCLUSION
The synergistic effects of BDSF and azoles may be useful as an alternative approach to control azole-resistant Candida infections.

OBJECTIVE:
To explore the effect of compound malt pills (CMP) on polycystic ovarian syndrome (PCOS) rat model induced by letrozole and the underlying mechanisms.
METHODS:
To establish a PCOS rat model, 48 female SD rats aged 6 weeks were randomly divided into 6 groups (n=8): A normal group, a model control group, a positive control group, a low-dose CMP group, a middle-dose CMP group, and a high-dose CMP group. Rats were treated for 21 days after the PCOS model was successfully established. Ovarian morphology changes were observed, and the expressions of ERα and ERβ was examined by immunohistochemistry, Western blot and RT-PCR, respectively.
RESULTS:
Compared with the normal group, the number of follicular cystic dilatation in the model control group was increased and the granulosa cells were decreased. After the treatment, the number of follicular cystic dilatation was reduced compared with the model control group, but the primordial follicles, corpus luteum and granulosa cells were increased. The expressions of ERα and ERβ in the model control group were significantly decreased (P<0.01), which were increased in the intervention groups (P<0.05 or P<0.01).
CONCLUSION
CMP may play a role in the treatment of PCOS by regulating the expressions of ERα and ERβ.

OBJECTIVETo study the effectiveness and safety of deferasirox (DFX) in the treatment of iron overload in children with β-thalassemia major.
METHODSTwenty-four β-thalassemia major children with iron overload who received regular blood transfusion were randomly enrolled. The serum feritin (SF) levels were measured in the patients after different doses of DFX treatment. The DFX treatment-related adverse events were observed. The values of cardiac MRI T2* and liver MRI T2* were compared between the patients receiving DFX treatment for 5 years and the patients treated with deferoxamine and deferiprone.
RESULTSThe patients with iron overload did not respond to DFX at the initial dose of 20-30 mg/kg•d. However, the SF level decreased significantly after the dose of DFX increased to 30-40 mg/kg•d (U=58, P<0.01). Serum liver transaminase elevation was the most common adverse effect, followed by non-progressive elevation in serum creatinine level. The mean SF level was significantly lower (1748±481 ng/mL vs 3462±1744 ng/mL; P<0.05), in contrast, the liver MRI T2* value was significantly higher (8.5±2.9 ms vs 2.7±1.9 ms; P<0.01) in patients receiving DFX treatment for 5 years than in the controls. There were no significant differences in the cardiac MRI T2* value between the two groups.
CONCLUSIONSDFX can reduce SF levels in a dose-dependent manner in children with β-thalassemia major. It can significantly lower liver iron overload but not cardiac overload. Serum liver transaminase elevation and non-progressive elevation in serum creatinine level are major adverse effects in DFX treatment.

During the last five decades, long-term therapy with immunosuppressive agents such as pulse cyclophosphamide in conjunction with high-dose corticosteroids has enhanced both patient survival and renal survival in patients with diffuse proliferative lupus nephritis. Nevertheless, severe side effects such as infectious complications remain the main cause of morbidity and mortality. Central nervous system aspergillosis is uncommon but life-threatening in lupus patients. In this single-patient case study, carotid aneurysm with sphenoidal sinusitis was suspected when severe epistaxis occurred during cyclophosphamide pulse therapy. With anti-fungal therapy, a graft stent was successfully deployed to the aneurysm and specimens of sphenoidal mucosa showed typical hyphae, indicating aspergillosis. Three months after stopping voriconazole treatment, two cerebral aneurysms that were revealed on MR images were successfully removed by aneurysmal clipping. The patient remained alive at one-year follow-up with lupus nephritis in remission. The rarity and high mortality of aspergillus-related fungal aneurysms have led to most cases being recognized postmortem. However, such aneurysms must be diagnosed early to prevent fatal complications by performing appropriate management such as surgical procedure or endovascular intervention.
