ABSTRACT

BACKGROUND: Aquagenic wrinkling of the palms (AWP) is an excessive and early palmar wrinkling occurring after brief immersion to water (BIW), and has been reported as a frequent finding among Cystic Fibrosis (CF) patients. OBJECTIVES: To investigate any associations of CF patients presenting AWP with other disease characteristics and explore the pathomechanism of AWP phenomenon. METHODS: We evaluated AWP in CF patients and assessed the AWP parameters of palmar wrinkling, oedema, papules, pruritus and pain at 3, 7 and 11 min after a BIW test with other disease characteristics. Statistical analyses explored the associations of AWP with genotype, lung function, pancreatic insufficiency, hyperhidrosis, personal and family history of atopy and sweat chloride levels. RESULTS: One hundred CF patients (mean age 10.4 years) were included in the analysis. The genotypic distribution was ΔF508/ΔF508: 47%, ΔF508/other: 41% and other/other: 12%. Statistically significant associations of Kaplan-Meier curves of the AWP parameters with various disease characteristics and personal/family history were detected. Wrinkling was associated with history of atopy, hyperhidrosis and levels of sweat chloride test. The time to presentation of oedema and the appearance of papules were associated with history of hyperhidrosis and age at diagnosis. Finally, time to appearance of pruritus was related to history of atopy and of hyperhidrosis. Regarding TEWL regression analysis showed significant associations with age at diagnosis (p = 0.024), sweat chloride test levels (p = 0.005), history of hyperhidrosis (p = 0.033), history of atopy (p = 0.002) and hepatic-pancreatic involvement (p = 0.027). CONCLUSIONS: The existence of a statistically significant association between AWP and the history of hyperhidrosis, atopy, sweat chloride levels and hepatic-pancreatic function in CF patients was detected. A strong association between AWP and CF was detected. AWP after BIW could be elicited easily and possibly can be used as an initial screening tool to diagnose an individual with symptoms and signs that raise the likelihood of CF.

ABSTRACT

BACKGROUND: Aquagenic wrinkling of the palms (AWP) is an excessive and early palmar wrinkling occurring after Brief Immersion to Water (BIW), and has been reported as a frequent finding among cystic fibrosis (CF) patients. OBJECTIVES: To evaluate and assess the diagnostic performance of BIW test as an initial screening tool for CF diagnosis. METHODS: We measured AWP in CF patients, CF-heterozygotes (CF-het) and normal controls. The AWP parameters of palmar wrinkling, oedema, papules, pruritus and pain were assessed at 3, 7 and 11 min after a BIW test was performed for all the participants. Statistical analyses explored the progression of AWP in time for the three groups and assessed the diagnostic performance of BIW test as a diagnostic screening tool for CF. RESULTS: A total of 250 individuals (100 CF patients, their 50 CF-het parents, 100 healthy controls) were included in the analysis. The average age in years (mean ± SD) was 10.4 ± 4.0 for CF, 35.9 ± 6.1 for CF-het and 10.5 ± 4.0 for controls. The rate of positives for AWP at 3 min among CF patients, CF-het and controls was 68%, 8% and 0%, respectively (P < 0.01). Kaplan-Meier analysis showed a clear trend towards earlier appearance of all five parameters in the direction controls < hetCF < CF (P values <0.01). The best diagnostic performance in detecting between CF patients and non-CF was achieved by the presence of papules and wrinkling at 7 min (sensitivity/specificity: 94.0%/98.3% and 100.0%/92.0%, respectively). CONCLUSIONS: A strong association between AWP and CF was detected. AWP after BIW could be elicited easily and possibly can be used as an initial screening tool to assess if an individual with symptoms and signs that raise the likelihood of CF is a CF patient.

ABSTRACT

BACKGROUND: Varicella-zoster virus (VZV) infection is usually benign but immunocompromised patients are at great risk for visceral dissemination and fatal outcome. During a nationwide varicella outbreak, several of our patients contracted the disease. We undertook studies of the epidemiology and the efficacy of antiviral treatment and immunoprophylaxis. PROCEDURE: During a 9-month period, 52 patients were exposed to cases of active varicella. Twenty-seven of these children were reexposed to active varicella > 1 month after their initial exposure. The exposure concerned 7 VZV waves of varying intimacy. In all cases, prophylaxis with intravenous immunoglobulin (IVIG), varicella zoster globulin (VZIG), or both was given. The spread of the disease was limited and only 6 patients (all immunosuppressed) developed varicella (7.6%). Three of 6 had been given IVIG and 3 VZIG + IVIG. All patients with varicella received acyclovir 30 mg/kg/day for 14 days. The disease was mild and all patients were ultimately cured. RESULTS: Our results show that prophylaxis was not 100% effective, but appearance to reduce the rate of spread. The differences in incidence among the regimens used were not significant. CONCLUSIONS: For the moment, immunoprophylaxis and acyclovir administration appear to be quite satisfactory in managing immunocompromised children exposed to VZV. This may change with the wider use of the varicella vaccine.
