Insights
Hidradenitis suppurativa (HS) patients have a higher prevalence of chronic kidney disease (CKD). Early assessment for CKD in HS patients is recommended to prevent disease progression.
Area of Science:
- Dermatology
- Nephrology
- Epidemiology
Background:
- Hidradenitis suppurativa (HS) is linked to comorbidities like diabetes and cardiovascular disease, which are risk factors for chronic kidney disease (CKD).
- The relationship between HS and CKD risk remains understudied.
Purpose of the Study:
- To investigate the prevalence of chronic kidney disease (CKD) in patients diagnosed with hidradenitis suppurativa (HS).
Main Methods:
- A cross-sectional, population-based study utilized data from the US National Inpatient Sample database.
- The study period spanned from January 1, 2002, to December 31, 2012.
- HS patients were compared to age- and gender-matched controls without HS.
Main Results:
- The prevalence of CKD was higher in HS patients (6.3%) compared to controls (4.3%).
- The association between HS and CKD was more pronounced in older patients (≥60 years), males, obese individuals, and those with diabetes, hyperlipidemia, or cardiovascular disease.
- The adjusted odds ratio for CKD in HS patients was 1.1 (95% CI: 1.014-1.176) compared to non-HS patients.
Conclusions:
- A potential association exists between hidradenitis suppurativa (HS) and chronic kidney disease (CKD).
- Prompt evaluation by a nephrologist for any signs of CKD in HS patients is advised for early diagnosis and management.
- Early detection may help mitigate the progression of CKD in individuals with HS.
Background:
Hidradenitis suppurativa (HS) is associated with several comorbidities such as diabetes mellitus and cardiovascular diseases. These comorbidities are also risk factors for chronic kidney disease (CKD), yet little is known about the risk of CKD in HS patients.
Objectives:
The objective was to study the prevalence of CKD in HS patients.
Methods:
Cross-sectional population-based study using the United States National Inpatient Sample database between January 1, 2002 and December 31, 2012 was performed.
Results:
We identified 23,767 hospital admissions for HS patients and 95,068 admissions for age- and gender-matched controls. The prevalence of CKD in HS patients was 6.3% (1,497/23,767) compared to non-HS controls which was 4.3% (4,052/95,068). The association of CKD was strongest in HS patients, who were ≥60 years old, 16.9% (475/2,811), male 7.3% (695/9,556), obese 7.8% (407/5,209), diabetic 12.5% (890/7,105), hyperlipidemic 13.3% (416/3,126), and had cardiovascular diseases 12.5% (631/5,045). The crude odds ratio of CKD in HS patients was 1.5 (95% CI: 1.420-1.605) compared to non-HS patients. The association remained significant after adjusting for important covariates with adjusted odds ratio of CKD in HS patients of 1.1 (95% CI: 1.014-1.176) compared to non-HS patients.
Conclusions:
Our findings show that there is a possible association of HS with CKD. Any signs of CKD should be assessed by a nephrologist as early diagnosis can hopefully prevent further progression.
