Risk factors and complications of lower limb cellulitis in Africa: a systematic review

OBJECTIVE

To summarise available data on the risk factors, complications and the factors associated with complications of lower limb cellulitis in Africa.

METHODS

We did electronic searches on PubMed, EMBASE, Scopus and African Journals Online from 1 January 1986 to 30 October 2017, extracted and summarised data on the risk factors, complications and the factors associated with the complications of lower limb cellulitis from eligible literature.

RESULTS

A total of seven studies were retained for final review after the search and screening processes. Local risk factors of cellulitis reported were: disruption of the skin barrier, neglected wounds, toe-web intertrigo, leg ulcers, use of depigmentation drugs and leg oedema. Obesity was the only reported general risk factor of cellulitis. Five studies reported on the complications of cellulitis which included: abscess formation, necrotising fasciitis, bullae, haemorrhagic lesions, necrosis, phlebitis and amputations. Nicotine addiction, chronic use of non-steroidal anti-inflammatory drugs, delay in the initiation of antibiotic treatment and elevated erythrocyte sedimentation rate were risk factors of complications of lower limb cellulitis identified from three studies.

CONCLUSION

This review highlights the important role of local risk factors in the pathogenesis of lower limb cellulitis in Africa. The association between voluntary skin depigmentation and lower limb cellulitis should alert public health authorities and the general population to the health risks associated with this practice. The identification and improved management of the risk factors of lower limb cellulitis and its complications could go a long way in decreasing the morbidity and health costs incurred by lower limb cellulitis in Africa.

Erysipelas of the thigh and the gluteal region: retrospective multicenter analysis of a very rare entity in 39 patients

BACKGROUND

Erysipelas of the thigh and the gluteal region are rarely described and not well characterized. Therefore we aim to describe the prevalence, clinical characteristics, and risk factors of these erysipelas types.

METHODS

The files of 1,423 patients with erysipelas were analyzed. Data from patients with erysipelas of the thigh or the gluteal region were compared between the two groups and with a control group with erysipelas of the lower leg.

RESULTS

The thigh was exclusively affected in 2.1%, and the gluteal region in 0.6% of erysipelas patients. Gluteal erysipelas had conspicuous irregular borders and sometimes appeared bilaterally. Major risk factors for erysipelas of both sites were previous surgical interventions. Gluteal erysipelas was common in patients with the metabolic syndrome and required a more intense antibiotic therapy.

CONCLUSION

Erysipelas of the thigh and the gluteal region are rare and significantly associated with prior surgical disruption of lymphatic vessels.
