1. Abstract
The term “diabetic hand” was
born to describe the complications of the diabetes mellitus on the hand
resulting in a rigid hand with a poor mobility. The traumatic wounds with soft
tissue involvement increase the risk of infection. Staphylococcus aureus
Methicillin-Resistant (MRSA) is the most common bacterium isolated in the hand
infections. The case report of a type 2 diabetic patient, dialysed with chronic
obstructive peripheral artery disease and Monckeberg sclerosis of the vessels
of the hands, ischemic necrosis of the right-hand fingers is reported by the
authors. In the diabetic patient the hands can
be infected in the same way that feet could be infected too. Several amputation
interventions have been performed with the intent of saving part of the hand.
The Diabetic Hand Syndrome (DHS) is an important pathology that requires strong antibiotics and surgery to avoid severe disability as rigidity, contracture and amputation. Apparently, in the last years good results are reported using antibiotic, surgical and hyperbaric treatment. In conclusion it would be wrong to ignore or underestimate this disease and any doctor should practice a scrupulous visit of the hands in the diabetic patient.

1. Introductio
The Diabetic Hand Syndrome (DHS) is definite as a clinical condition based on a
vascular, neuropathic and infective pathogenesis caused by a chronic
hyperglicemy with or without a pre-existing ischemy triggered by traumatic
lesions of the upper limbs. Our impression is that in the last 20 years the interest
about this pathology is going decreasing so that most of the doctors ignore the
existence of this disease [1]. The term
“diabetic hand” was born to describe the complications of the diabetes mellitus
on the hand resulting in a rigid hand with a poor mobility. The immunodeficiency
causes a higher risk of severe hand infections, sometimes life-threatening. The
outcome of the hand infection depends by the early diagnosis and treatment [2]. The morbility of the DHS in terms of loss job, inability and permanent
disability compared to the diabetic foot is sharply higher. However, in the
last years the decreasing interest is proved by the poor scientific
publications on the DHS [3]. The compact anatomy of the hand promotes a
rapid propagation of the infection with severe damages. The etiology of the
disease is multi-factorial. The traumatic wounds with soft tissue involvement
increase the risk of infection. The most common bacterium is the staphylococcus
(Table 1) but also other microorganisms can be
involved both as single bacterium infection and as polimicrobic infection
including Gram- bacteria (Enterobacter, Streptococcus, Pseudomonas aeruginosa, anaerobic bacteria and fungal
infection) [4,5].
Staphylococcus aureus Methicillin-Resistant (MRSA) is the most common bacterium isolated in the hand infections. The fungal infection can result in a trivial onychomycosis but also in a life-threatening disease if the infection is severe with deep layers involvement. The viral infections are rare, anyway sometimes Papillomaviridae, Herpesviridae, Picornaviridae (coxsackievirus and enterovirus) and Poxviridae (orthopoxvirus and parapoxvirus) were isolated in patients with DHS. In the study published by Lamm and Choi (2004) the 49% of the infections were caused by Gram+ bacteria and the 47,6% by Gram- bacteria. Staphylococcus aureus was the most common bacterium isolated in the hand infections (34%). Enterococcus was isolated in the 8% of the cases. The Gram- bacteria Klebsiella pneumoniae, Citrobacter spp, Morganella morganii and Enterobacter spp were isolated respectively in 7%, 7%, 5,6% and 5,6% (Table 1) [4].
The DHS is more common in patients affected by diabetes mellitus type II rather than diabetes mellitus type I. Anyway, the early diagnosis and treatment are more important than the type of diabetes and not all of the symptoms are related to the diabetes. The natural evolution of the DHS is the fulminant sepsis due to the infection and to the progressive hand necrosis (Meleney’s gangrene).
2. Review of the Literature
Usually the hand is in an advanced condition of palmar deep sepsis and/or soft tissue infection. Often a partial amputation must be performed and nevertheless the mortality rate is significant. The stereotypical sepsis characteristics in the diabetic hand of the tropical population were studied by Gill, et al. (2003) [6] and they suggested the term of “tropical diabetic hand syndrome”. We have poor data on this syndrome that suggest poor results. The outcome data on the "tropical diabetic hand syndrome" are limited, but the information available generally suggests poor results. The study of Akintewe, et al. in 1984 [1] indicates that in 4 patients out of 5 a partial amputation was necessary. In the most representative study (31 patients in Tanzania), Abbas, et al. [6] shows that in the 13% of the cases a full arm amputation was performed with a significant mortality rate (13%). These patients would need a prolonged hospitalization with infusional antibiotics and 2/3 would need a surgical treatment (debridment, incision and drain or amputation).
Bacteria are the most involved microorganisms, but
also fungal, viral and protozoal infections are described [3, 7]. In the diabetic hand infections Gram- bacteria
were isolated in the 52% of patients. In the DHS Gram- infections were reported
in 52% [8]. Gram- predominancy (Pseudomonas
10,6%, Proteus
7,8%, Enterobacter
5,7%), Gram+ bacteria (S. aureus 15,6%, Streptococcus beta-haemolyticus 12,1%, S. viridans
7,1%) were found in diabetic patients. Candida albicans was found just in the diabetic hand group
(2,8%) (Table 2).
The rate of Gram- bacteria was between 31-73% in workers
[2]. Different groups of Gram- bacteria were
reported in patients affected by diabetes. These groups include: E. coli 0,72-4,2% [2], Proteus
(Vulgaris Proteus
in 4,2%) [2], Pseudomonas aeruginosa (1,3-7,2%) [2], Klebsiella (3,5-7%) [2],
Enterobacter
(1,9- 5,6%) [2] and Aerobacter aerogens in 0,72% [2]. Klebsiella
was the most common Gram- bacterium isolated jointly with Staphylococcus in polimicrobic
infections (Jalil, et al.) [9] and Klebsiella,
Enterobacter,
Proteus
and E. coli,
were found in 25% of microorganisms by Belcher, et al. [10].
Connor, et al. [11] reported Gram-
bacteria in 31% including Escherichia coli, Pseudomonas aeruginosa, Proteus vulgaris, Klebsiella,
Serratia,
Haemophilus,
Enterobacter,
Eichenella,
Pasteurella
and Neisseria. Dorko, et al. [12] reported
Neisseria
spp., Staphylococcus
Coagulase negative between 5,7% and 12,6% (8); Streptococcus spp in 5,6-16% [2]. Staphylococcus β-haemolyticus were mostly S. pyogenes between 3,6 and 12,5% [2].
Dorko et al. [12] reported Streptococcus β-haemolyticus in 22,4%.
Not-β-haemolyticus S.Viridians were
found in 1,3% [7], 2,16% [7]. Stevenson, et al. [13] reported
S. faecalis in 0,7%-1,7%. Streptococcus agalactiae was isolated in a patient
with diabetic hand [2]. Enterococcus was isolated in four
cases and in three of them it was E. faecalis (9%) [2], while anaerobic bacteria were reported in 9%.
Stevenson, et al. found Bacteroides in 5,9% and others anaerobic bacteria in
5,3% of hand infections. Lastly Eichenella in 2,7%, Prevotella (1,5%), Peptostreptococcus
(1,2%) [2]. Connor, et al. [11] isolated anaerobic bacteria in 9% including Clostridium
perfringens, Bacteroides, Fusobacterium and Veillonella. A fungal infection should
be considered in the differential diagnosis of the hand infection in the
immunocompromised patient or in a not-responder patient to the standard
treatment. In the study published by Jalil et al in the 10,3% Candida
was isolated [9] and it has been reported as associated
with chronic paronychia. Viral infection was caused mostly by herpes simplex
HSV 1 e HSV2.
3. Case Study
Mister F., 58 years old, is a little business owner with a long story of
disease. He got sick with diabetes mellitus type 2 when he was 31 and at 48
started hemodialysis due to renal complications. In 1989 high values of
glycemia (500 mg/dL), triglycerides (1500 mg/dl), cholesterol (700 mg/dL) were
detected. In 1999, with a reported creatinine >9 mg/dL started hemodialysis
3 times/week. Since then arterial insufficiency begins with lower limbs ulcers
and both feet finger amputations. In 2012 right leg trans-tibial amputation was
mandatory and in the 2014 several right hand finger amputations were performed.
In our patient, in addition to functional and angiographics diagnostic
techniques, a simple hand X-ray highlighted that the hand’s vessels were
completely enclosed in a wide calcium
shell coming up to vessels of the small phalanges (Figure 1) (Monckeberg’s
sclerosis, frequent around the arteries of the lower limbs, rare around those
of the upper limbs).
Then we decide to perform a tissue debridement. The surgical treatment
is very gentle as the small vessels disease is really nasty and irreversible,
intractable, which conditions a perfusion however reduced, so it’s primary to
avoid high pressure tissue zone (tight stitches, folded flaps…) that could be
the trigger for the ischemic necrosis. The use of dermal replacement based on
ialuronic acid (HMPA®) (Figure 2). Allows a reconstructive surgery
with functional preservation of the hand (07.01.2015).
At the right hand, furthermore we
perform a partial resection of the IV finger (01.03.2017) (Figure 3,4) shows at MRI the
vascular and bone situation with evidence of vessels calcification
(Monckeberg’s sclerosis).
One month after begins ischemic necrosis of the I finger (Figure 5) so a
metacarpophalangeal joint resection is performed (5.4.2017) (Figure 6) with diaphyseal
resection of the I metacarpus and closing using a sliding flap. Two months
after we perform a surgical revision of the II finger (Figure 7) and a partial
resection of the proximal phalanges (21.6.2017). The current situation is shown
in (Figure 8).
4. Discussion
Not everybody knows that in the diabetic patient the hands can be infected in
the same way that feet could be infected too. (Montes de Oca 2008) [14].
Three are the causes of the ischemia in the dialysis
patient’s hand:
1. Arteriovenous fistula that steals oxygenated blood to
the hand;
2. Big vessels disease that prevents blood from perfusing
the hand;
3. Small vessels disease (metacarpal and digital vessels) acts as another obstacle to the hand’s blood circulation.
The associated factors in the diabetic hand syndrome are similar to the associated factors in the lower limbs syndrome: 1. High levels of glycemia. 2. Neuropathy due to the hyperglycemia, metabolic pathway that leads to an increased intraneural sorbitol level. The not-zymotic proteic glycation determines a depletion of the myoinositol levels and ATP decreased levels and neuronal degeneration, slower conduction velocity and higher glycated haemoglobin, proving medium-high levels of glycemia in the last six-eight weeks. 3. The vascular theory: hyperglycemy causes reologic modifies with a subsequent increased endoneural vascular resistance, blood flow reduction and neural hypoxemia. 4. The diabetes mellitus is a risk factor for the arteriolar compromising and the atheroma making process, progression and complications (stenosis, obliteration) with a decreased blood flow, perfusion pressure and ischemia. 5. Mechanical, chemical, physical, thermal or biological trauma are risk factors.
In our review, gram+ bacteria were isolated in the 50% of the hand infections and the most common bacterium was S. aureus (Tab. II). According to this result we use flucloxacillin and erythromycin in the first line treatment regardless to the fact that in the DHS Gram- bacteria were found too. Diabetes promotes infections and has negative aftermath on the carbohydrate metabolism and glycemia. Firstly, Mann and Peacock [15] noted a Gram- predominancy in DHS in 1977, subsequently Francel, et al. [16] had different results with a mixed colture grow (63%). These infections are related with a more severe tissue damage and secondary deformity. In 1998, in a 12 years study, Gunther [17] enlisted 128 diabetic patients. Mansigh and Sawh [18] used a double antibiotic therapy to destroy both Gram+ and Gram- bacteria. This predominancy inversion was not demonstrated in others high risk group as in the alcohol addiction and abuse, HIV patients, intravenous drugs addicts and steroids addiction. Kour, et al. [19] reported the negative effects of the gram- and mixed infections on the wounds. In the Lamm and Choi study, 3 out of 5 diabetic patients had a Gram- infection and required surgery and 2 or more fingertip amputations. It demonstrates the importance to choose the right antibiotics to treat Gram+ and Gram- infections. Gentamicin and penicillin penicillinase resistant (cloxacillin, ampicillin, penicillin G) combination could be the best first line treatment but the renal function and gentamicin blood levels must be monitorated.
5. Conclusion
The diabetic hand syndrome is common in young-adult people, in diabetes mellitus type II with a poor metabolic control and subsequent high level of the glycated haemoglobin, therefore with a high risk of complications (neuropathy of peripheral arteries). Trauma is the trigger for the infection process, late diagnosis and treatment lead to a high amputation risk and to an increased morbidity and mortality. The surgical treatment should: save life, preserve the function and, lastly, look out for aesthetics. Based on evidences, we can divide the DHS in 4 phases: 1. superficial wound and ulcer, deep wound and ulcer, 3. Abscess and osteomyelitis, 4. Necrosis and gangrene. The DHS is an important pathology that requires strong antibiotics and surgery to avoid severe disability as rigidity, contracture and amputation. The success depends by an early diagnosis and antibiotic tratment in the first 24-48h with immobilization of the limb. If the infection is not under control the surgical option must be considered (incision, drain, debridment or amputation). The right choice of the antibiotics depends by the knowledge of the most common involved microorganisms. Once we know the microorganisms involved we should change the antibiotics based on the antimicrobial susceptibility.
In the last 10 years the relation among risk factors, mostly diabetes mellitus
and Gram- infections, has been studied. The Gram- infections can’t be treated
just with a first line antibiotic treatment but these patients should be
treated in hospital to treat the hand infection and to optimize the metabolic
control of the disease, also using insulin. Though the bacteria involved in
skin and tissue infections are very common (Gram+, Staphylococcus, Streptococcus), sometimes bowel
bacteria are involved (Gram- and an Aerobes). The first line treatment provides
the use of broad-spectrum intravenous antibiotics and possibly the surgical
drain in case of abscess. The late treatment increases the risk of amputation.
In case of amputation or loss of function after surgery rehabilitation should
be considered. Apparently,
in the last years good results are reported using antibiotic, surgical and
hyperbaric treatment. In conclusion it would be wrong to ignore or
underestimate this disease and any doctor should practice a scrupulous visit of
the hands in the diabetic patient.
