Effects of oral cetirizine combined with budesonide inhalation on immune inflammatory response in children with acute asthma attack

Objective: To study the effects of oral cetirizine combined with budesonide inhalation on immune inflammatory response in children with acute asthma attack. Methods: Children with acute asthma attack who were treated in Beijing Luhe Hospital Affiliated to Capital Medical University between April 2014 and February 2017 were selected and randomly divided into two groups, observation group received oral cetirizine combined with budesonide inhalation therapy, and control group received budesonide inhalation therapy. The contents of CD4+T cell subsets and the expression of immune transcription factors in peripheral blood as well as the contents of CD4+T cytokines and inflammatory mediators in serum were measured after 1 week of treatment. Results: After 1 week of treatment, Th1 and Treg contents as well as BCL11B, STAT4 and SOCS3 mRNA expression in peripheral blood as well as IFN-γand IL-10 contents in serum of observation group were greatly higher than those of control group while Th2, Th17 and Th22 contents as well as STAT1 and STAT3 mRNA expression in peripheral blood as well as IL-4, IL-17, IL-22, HMGB1, Periostin, Eotaxin and ADAM33 contents in serum were greatly lower than those of control group. Conclusion: Oral cetirizine combined with budesonide inhalation is more effective than budesonide inhalation alone to modulate the immune inflammatory response in children with acute asthma attack.

Cetirizine regulates scleroderma skin fibrosis in mice via the TGF-β1/Smad3 signaling pathway

Objective:To investigate the effect of cetirizine on the fibrosis of skin tissue in systemic sclerosis(SSc)mice and its mechanism of action.Methods:Thirty-two BALB/C mice were randomly divided into a blank group,a model group,a cetirizine low-dose group,and a cetirizine high-dose group,with eight in each group.The blank group was injected with normal saline on the back,and the other three groups were injected with bleomycin on the back to prepare SSc mouse models.The mice were injected once a day for 28 consecutive days,while the normal group and the model group were given saline.The dose group was administrated intragastrically at 2 mg/kg and 5 mg/kg,respectively,for 28 consecutive days.Detect the thickness of the dermis by taking the skin tissue in the back injection area of each group.Hematoxylin-eosin staining(HE)and Masson staining.Sample hydrolysis method to detect hydroxyproline(HYP)content in skin tissue.Immunohistochemical detection ofα-smooth muscle actin(α-SMA)expression in skin tissues.Enzyme-linked immunosorbent assay(ELISA)to detect serum interleukin(IL-6,IL-10)and transforming growth factor(TGF-αand TGF-β1).Quantitative real-time PCR(qRT-PCR)was used to detect the expression levels of collagen type I(COL1A1),type III collagen(COL3A1),Smad homolog 3(Smad3),and TGF-β1 mRNA.Western blot was used to detect the expression levels of COL1A1,COL3A1 and p-Smad3.Results:Compared with the blank group,the dermis thickness and HYP content of the model group increased,the skin tissue lesions and fibrosis were more severe,theα-SMA positive expression intensity in the skin tissue was higher,and the serum IL-6,IL-10,TGF-α,TGF-β1 content increased,COL1A1,COL3A1,Smad3,TGF-β1 mRNA expression levels increased in skin tissues,COL1A1,COL3A1,p-Smad3 protein expression increased,the differences were statistically significant(P<0.05).Compared with the model group,the dermal thickness and HYP content of the low and high dose cetirizine groups were reduced,the degree of skin tissue lesions and fibrosis was improved,the expression ofα-SMA in skin tissues was weakened,the levels of IL-6,IL-10,TGF-α,TGF-β1 in serum were reduced,the expression levels of COL1A1,COL3A1,Smad3 and TGF-β1 in skin tissues were reduced,and the expression levels of COL1A1,COL3A1,and p-Smad3 proteins were reduced,the decrease in the high-dose group was more significant,and the differences were statistically significant(P<0.05).Conclusion:Cetirizine can improve the degree of fibrosis of skin tissue in SSc mice and reduce the immune inflammation response.The mechanism of action is related to the TGF-β1/Smad3 signaling pathway.

Resolution of night terrors after discontinuation of cetirizine

We present a 4-year-old girl with allergies and asthma who developed night terrors after initia- tion of montelukast at 2 years of age. Montelu-kast was discontinued and cetirizine was started. Nigh terrors persisted. Sleep diaries were col- lected and diagnosticpolysomnogram (PSG) was ordered. Sleep diaries revealed an average sleep time of 10 hours with night terrors occur- ring three nights a week approximately two hours after sleep onset. The PSG did not show evidence of sleep disordered breathing or peri- odic leg movements. Cetirizine was discontin- ued and the night terrors ceased. Upon re-intro- duction of the medication, the sleep terrors re- curred.

Effect of budesonide and cetirizine hydrochloride on neurotrophic factor, airway function and chemokines CCL17 and CCL22 in patients with allergic rhinitis

Objective: To investigate the effect of budesonide combined with cetirizine hydrochloride on neurotrophic factor, airway function and chemokines CCL17 and CCL12 in patients with allergic rhinitis. Methods: A total of 123 patients with Allergic Rhinitis were randomly divided into three groups, A group treated with budesonide nasal spray, B group treated with cetirizine hydrochloride, C group treated with budesonide combined with cetirizine hydrochloride, then the Neurotrophic factors, airway function indexes and chemokines CCL17 and CCL12 levels in three groups were compared. Results: Before the treatments, the three groups of patients in neurotrophic factor, airway function index and chemokines CCL17, CCL22 have no differences, Compared with before the treatments, after receiving different treatments, the three groups of patients in all indicators were Showed significant differences. In the indexes of neurotrophic factor (NGF, BDNF, NT-3mRNA expression), there was no significant difference between group A and group B, and group C was lower than group A and B. In airway function indexes (FVC, FEV1 and PEF), A group was significantly higher than B group, C group was significantly higher than A group;In the chemokines CCL17 and CCL22 indicators, C group was lower than A group, A group was lower than B group, the difference was significant. Conclusions: Budesonide combined with cetirizine hydrochloride in the treatment of Allergic Rhinitis, can effectively control the patients' neurotrophic factor, pulmonary ventilation and chemokine CC17, CCL22 indicators, the effect is better than Budesonide alone or Cetirizine hydrochloride.

Cetirizine-induced hepatotoxicity:case series and review of the literature

Drug-induced liver damage is a frequently encountered clinical table caused by many drugs.Cetirizine is a widely preferred and prescribed antihistaminic agent for allergic disorders due to its non-sedative properties.In view of the literature,we present four cases of hepatotoxicity due to cetirizine use.We conclude that in patients with high levels of liver enzymes of unknown origin,cetirizine as well as other hepatotoxic drugs should be reconsidered.

Simultaneous Determination of Amlodipine with H₁-Receptor Antagonists by Reversed Phase High Performance Liquid Chromatography and Application to Interaction Studies

A rapid, fast and precise method has been developed and validated for the simultaneous determination of amlodipine with H1-receptor antagonists (cetirizine, fexofenadine, and buclizine) from dosage forms. The chromatography was performed on a Purospher? Star, C18 (5 mm, 250 × 4.6 mm) column using acetonitrile: buffer (0.01 mM) (40:60, v/v, pH adjusted to 3.0), as a mobile phase. The mobile phase was pumped at a flow rate of 1.0 mL·min-1 and UV detection was performed at 240 nm. The method was validated for linearity, accuracy, precision and specificity. The method was applied to study the interaction between amlodipine and H1-receptor antagonists. These interactions were carried out in simulated gastric juice (pH 1), simulated full stomach (pH 4), blood pH (pH 7.4) and simulating GI (pH 9). The interacting drugs were heated at 37℃ with intermit-tent shaking and the samples were withdrawn every thirty minutes for three hours and drug contents were analyzed by RP-HPLC techniques. In most cases the in vitro availability of amlodipine was decreased. It was observed that the change in in vitro availability was pH dependent.

A Novel Vehicle Formulation for Treatment of Inflammatory Skin Diseases

Objective: To test the efficacy of a new topical vehicle formulation containing cetirizine in emu oil in treating inflammatory skin conditions. Methods: A single blind half body comparative study of patients with psoriasis, atopic and stasis dermatitis were all treated with midpotency topical steroid (desoximethasone) in propylene glycol base, desoximethasone and cetirizine in propylene glycol base, desoximethasone in emu oil base and desoximethasone with cetirizine dissolved in emu oil. Results: Based on patients’ ranking of creams’ efficacy, and supported by photographic data and investigators’ clinical assessment, results clearly indicated that desoximethasone and cetirizine in emu base was statistically more efficacious than either desoximethasone alone or with cetirizine in neutral propylene glycol base or desoximethasone in emu oil base (without cetirizine). Conclusions: Cetirizine and emu oil, having inherent anti-inflammatory and other beneficial properties synergistically, and by different biochemical pathways, enhance and magnify each other’s pharmaceutical effects that are useful in treatment of skin inflammatory diseases.
